During her dermatology residency at Yale University in the late 1980s, Tina S. Alster, MD, met a 44-year-old woman who changed the trajectory of her professional career.

During her clinic visit, the woman explained that she always wore heavy facial makeup to hide her port-wine stain birthmark – a vascular malformation that she kept secret from her husband and teenage son. “She was very good about covering it,” recalled Dr. Alster, who is the founding director of the Washington Institute of Dermatologic Laser Surgery and clinical professor of dermatology at Georgetown University, Washington. “She removed a small amount of makeup for me so I could take a look at it. I had just finished reading an article about using a laser for birthmarks; it had just been published. I told her, ‘There’s something new; we don’t have it at Yale, but I read about treatment that could hone in on birthmarks.’ I promised her I would find out more details.”

A few days later, Dr. Alster pored through stacks of medical journals at Yale’s library and relocated the article she’d seen by first author Oon Tian Tan, MD, PhD, of the department of dermatology at Boston University Medical Center. It described use of the flashpump-pulsed tunable dye laser to treat port-wine stains in 35 children (N Engl J Med. 1989;320:416-21). After giving the article a more thorough read, Dr. Alster became so intrigued by the technology it described that she moved to Boston the following year for a dermatology fellowship with Dr. Tan and joined the ranks of early clinicians who used lasers for treating port-wine stains and other dermatologic conditions.

“That was at a time when there were only a handful of pulsed dye lasers in the world, and the first time I used it was when I went to Boston,” she said. “It was life-changing. You think, ‘Isn’t this great for children with port-wine stains.’ Your heart breaks for them, but I also felt compassion for adults who had suffered a lifetime of stares, including the woman who propelled me to look into this. She ended up coming to Boston during my fellowship and had her birthmark removed, so I changed her life, but she changed mine as well.”

The real credit for that series of events, Dr. Alster continued, belongs to John A. Parrish, MD, and R. Rox Anderson, MD, who in 1983 published the concept of selective photothermolysis, a seminal work that shifted the paradigm for how lasers and other light sources are designed for skin diseases and conditions (Science. 1983 Apr 29;220(4596):524-7). The first pulsed dye laser was built on this concept, an approach that minimized or eliminated the unwanted tissue damage and significant scarring that impeded therapeutic use of laser energy for port-wine stains and other lesions prior to that time. “Lasers that were built subsequent to that seminal paper focused our attention on building lasers that were specific for treatment of certain skin conditions,” Dr. Alster said. “Selective photothermolysis catapulted not only our understanding of how lasers interact with the skin, but allowed us to identify things in the skin that we could potentially target with this new laser technology, and to build laser systems that were specific to those purposes.”

In the late 1970s, Dr. Parrish, who played a key role in making psoralens plus ultraviolet A safe and effective for patients with severe psoriasis, turned his attention to studying lasers in his lab at Harvard Medical School. He hired R. Rox Anderson, a recent graduate of the Massachusetts Institute of Technology, as a technician. “Rox then got interested in medicine and went to medical school at Harvard, got interested in dermatology, and then worked in my lab a little bit more,” said Dr. Parrish, who founded the Wellman Center for Photomedicine at Massachusetts General Hospital, Boston.

“Rox was interested in port-wine stains because of his rotation through pediatrics and was theorizing about how lasers could improve port-wine stains and hemangiomas. I think he first thought of that through the physics of what would be needed. He was thinking, ‘What are these hemangiomas under the microscope? What does the target look like, and what do you need to do to promote healing without scarring? You would have to be able to heat for this duration and this time and at this wavelength.’ He matched the physics of lasers with the pathophysiology of port-wine stains, and together we figured out how to deliver the right energy at the right wavelength at the right time. In fact, at the time, there was no ideal laser. We had to convince a laser manufacturer to build a tunable dye laser, which is what we ended up using around the specifications that we wanted for this treatment.”

Prior to the theory of selective photothermolysis, lasers were a blunt instrument. “They would target the skin but you wouldn’t just selectively target something; you’d get a result you didn’t want,” said Mathew M. Avram, MD, JD, director of laser, cosmetics, and dermatologic surgery at Massachusetts General Hospital.

Once pulsed dye lasers that incorporated principles of selective photothermolysis hit the marketplace, clinicians could treat and improve port-wine stains without scarring the skin. They could even improve scarring from port-wine stains that had been previously treated with the argon laser, the subject of early published work by Dr. Alster (Lasers Surg Med. 1993;13[3]:368-73). “When we treated port-wine stains with the pulsed dye laser on top of the argon laser scars, we observed that the scars were looking better,” Dr. Alster said. “From that observation, we were able to demonstrate improvement of a wide range of scars: traumatic and burn scars, surgical scars, acne scars, and scars caused by other lasers. But it all started with the pulsed dye laser for treating port-wine stains that had scars in them.”

Another game-changing technology developed by Dr. Anderson came in the early 2000s with the Food and Drug Administration clearance of the Fraxel laser, which is based on the concept of fractional photothermolysis. With this technology, “instead of treating skin to a certain depth, you treat a fraction of it, anywhere from 5% to 40% of the skin,” Dr. Avram explained. “You go in deeper, but you leave surrounding viable tissue that is not affected by the laser. That serves as viable tissue to promote healing. The laser goes in deeper but it’s fractional, so there are skip zones in between the lasers that are going into the skin. You can do this with the CO₂ and erbium YAG lasers.” Since hitting the marketplace, the FDA has cleared the use of Fraxel for a number of indications, from periorbital wrinkles and acne scars to surgical scars and melasma.

Dr. Parrish predicted that the next frontier for the advancement of lasers in dermatology will involve the treatment of photodamaged skin. “I’m not sure which technology is going to win,” he said.

Dr. Avram anticipates that dermatologic lasers of the future are going to be more effective, safer, and result in less downtime for patients. “I think we are going to be able to treat skin of color more safely and more effectively, and I think we’re going to become much more successful,” he said. “At some point, the standard of care of treatment for skin cancer will involve lasers and light sources. With all the advances that have happened in the last 50 years, sometimes you wonder, are we at a time to pause, or is most of the story behind us? I think that the advances in innovation that are occurring are going to accelerate greatly as we pass the 50th anniversary. In due credit, laser therapy has completely revolutionized the field of dermatology and has completely revolutionized the way we practice medicine. That will only accelerate in the future.”

Dr. Alster emphasized a “safety first” approach to her hopes for the future. “My wish is that we educate people to know that, while lasers have become ubiquitous and we’ve made them safe, they’re still only safe in the right hands,” she said. “There’s not a day that goes by when I don’t have somebody referred to me who’s been mishandled. There’s no reason for that. With proper training, the risk of bad side effects or complications is markedly reduced.”

Two important lessons about managing patients with multiple sclerosis (MS) and COVID-19 have emerged from a hospital clinic in Madrid that managed COVID-infected patients with MS through the peak of the pandemic: Combined polymeric chain reaction and serology testing helped avoid disease reactivation in asymptomatic carriers during the pandemic peak, although after the peak PCR alone proved just as effective; and infected MS patients could stay on their MS medications while being treated for COVID-19, as fewer than one in five required hospitalization.

Virginia Meca-Lallana, MD, a neurologist and coordinator of the demyelinating diseases unit at the Hospital of the University of the Princess in Madrid, and colleagues presented their findings in two posters at the Joint European Committee for Treatment and Research in Multiple Sclerosis-Americas Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS-ACTRIMS) 2020, this year known as MSVirtual2020.

“MS treatments don’t seem to make the prognosis of COVID-19 worse, but it is very important to evaluate other risk factors,” Dr. Meca-Lallana said in an interview. “MS treatments prevent the patients’ disability, and it is very important not to stop them if it isn’t necessary.”

The results arose from a multidisciplinary safety protocol involving neurology, microbiology, and preventive medicine that the University of Princess physicians developed to keep MS stable in patients diagnosed with SARS-CoV-2.

The researchers obtained 152 PCR nasopharyngeal swabs and 140 serology tests in 90 patients with MS over 3 months before starting a variety of MS treatments: Natalizumab (96 tests), ocrelizumab (36), rituximab (3), methylprednisolone (7), cladribine (4), and dimethyl fumarate (3). The protocol identified 7 asymptomatic carriers—7.8% of the total population—5 of whom had positive immunoglobulin M and G serology. The study also confirmed 5 patients with positive IgM+IgG serology post-infection, but no COVID-19 reactivations were detected after implementation of the protocol.

“The safety protocol reached its objective of avoiding disease reactivation and clinical activation in asymptomatic carriers,” Dr. Meca-Lallana said.

The second poster she presented reported on the real-world experience with SARS-CoV-2 in the MS unit at her hospital. The observational, prospective study included 41 cases, 38 of which were relapsing-remitting MS and the remainder progressive MS. The patients had MS for an average of 9 years.

“We need more patients to draw more robust conclusions, but in our patients, MS treatments seem safe in this situation,” Dr. Meca-Lallana said. “We did not discontinue treatments, and after our first results, we only delayed treatments in patients with any additional comorbidity or when coming to the hospital was not safe.”

A total of 39 patients were taking disease-modifying therapies (DMTs): 46.3% with oral agents, 39% with monoclonal antibodies, and 10% with injectable agents; 27 patients were previously treated with other DMTs. The median Expanded Disability Status Scale (EDSS) was 2.5, and 11 patients had clinical activity the previous year. Eighteen cases were confirmed by PCR or serology, or both, and 23 were diagnosed clinically.

Among the patients with MS and COVID-19, 17% were admitted to the hospital. Six patients had pneumonia, but none required admission to the intensive care unit, and no deaths occurred. Three patients had other comorbidities. Admitted patients tended to be older and had higher EDSS scores, although the difference was not statistically significant. MS worsened in 7 patients, and 10 patients stopped or paused DMTs because of the infection.

“Multiple sclerosis is a weakening illness,” Dr. Meca-Lallana said. “MS treatments do not seem to make the prognosis of COVID-19 worse, but it is very important to evaluate other risk factors.”

The SARS-CoV-2 infection does not seem to result in a more aggressive form of the disease in MS patients, and selective immunosuppression may improve their outcomes, she noted.

“MS treatments avoid the patient’s disability,” the investigator added, “and it is very important not to stop them if it isn’t necessary.”

Dr. Meca-Lallana had no relevant financial disclosures.

The second poster she presented reported on the real-world experience with SARS-CoV-2 in the MS unit at her hospital. The observational, prospective study included 41 cases, 38 of which were relapsing-remitting MS and the remainder progressive MS. The patients had MS for an average of 9 years.

“We need more patients to draw more robust conclusions, but in our patients, MS treatments seem safe in this situation,” Dr. Meca-Lallana said. “We did not discontinue treatments, and after our first results, we only delayed treatments in patients with any additional comorbidity or when coming to the hospital was not safe.”

A total of 39 patients were taking disease-modifying therapies (DMTs): 46.3% with oral agents, 39% with monoclonal antibodies, and 10% with injectable agents; 27 patients were previously treated with other DMTs. The median Expanded Disability Status Scale (EDSS) was 2.5, and 11 patients had clinical activity the previous year. Eighteen cases were confirmed by PCR or serology, or both, and 23 were diagnosed clinically.

Among the patients with MS and COVID-19, 17% were admitted to the hospital. Six patients had pneumonia, but none required admission to the intensive care unit, and no deaths occurred. Three patients had other comorbidities. Admitted patients tended to be older and had higher EDSS scores, although the difference was not statistically significant. MS worsened in 7 patients, and 10 patients stopped or paused DMTs because of the infection.

“Multiple sclerosis is a weakening illness,” Dr. Meca-Lallana said. “MS treatments do not seem to make the prognosis of COVID-19 worse, but it is very important to evaluate other risk factors.”

The SARS-CoV-2 infection does not seem to result in a more aggressive form of the disease in MS patients, and selective immunosuppression may improve their outcomes, she noted.

“MS treatments avoid the patient’s disability,” the investigator added, “and it is very important not to stop them if it isn’t necessary.”

Dr. Meca-Lallana had no relevant financial disclosures.

The nation’s largest physician association is seeking to establish a path to payment for extra practice expenses required to care for patients during the COVID pandemic and possible future public health emergencies.

The American Medical Association on Sept. 8 announced that a new code, 99072, is intended to cover additional supplies, materials, and clinical staff time over and above those usually included in an office visit when performed during a declared public health emergency, as defined by law, attributable to respiratory-transmitted infectious disease, the AMA said in a release.

Fifty national medical specialty societies and other organizations worked with the AMA’s Specialty Society RVS Update Committee over the summer to collect data on the costs of maintaining safe medical offices during the public health emergency. It has submitted recommendations to the Centers for Medicare & Medicaid Services seeking to persuade the federal agencies to recognize the new 99072 payment code.

The intention is to recognize the extra expenses involved in steps now routinely taken to reduce the risk for COVID transmission from office visits, Current Procedural Terminology Editorial Panel Chair Mark S. Synovec, MD, said in an interview. Some practices have adapted by having staff screen patients before they enter offices and making arrangements to keep patients at a safe distance from others during their visits, he said.

“Everyone’s life has significantly changed because of COVID and the health care system has dramatically changed,” Dr. Synovec said. “It was pretty clear that the status quo was not going to work.”

Physician practices will welcome this change, said Veronica Bradley, CPC, a senior industry adviser to the Medical Group Management Association. An office visit that in the past may have involved only basic infection control measures, such as donning a pair of gloves, now may involve clinicians taking the time to put on more extensive protective gear, she said.

“Now they are taking a heck of a lot more precautions, and there’s more time and more supplies being consumed,” Ms. Bradley said in an interview.
 

Code looks ahead to future use

The AMA explained how this new code differs from CPT code 99070, which is typically reported for supplies and materials that may be used or provided to patients during an office visit.

The new 99072 code applies only during declared public health emergencies and applies only to additional items required to support “a safe in-person provision” of evaluation, treatment, and procedures, the AMA said.

“These items contrast with those typically reported with code 99070, which focuses on additional supplies provided over and above those usually included with a specific service, such as drugs, intravenous catheters, or trays,” the AMA said.

The CPT panel sought to structure the new code for covering COVID practice expenses so that it could not be abused, and also looked ahead to the future, Dr. Synovec said.

“It’s a code that you would put on during a public health emergency as defined by law that would be related to a respiratory-transmitted infectious disease. Obviously we meant it for SARS-CoV-2,” he said. “Hopefully we can go another 100 years before we have another pandemic, but we also wanted to prepare something where if we have another airborne respiratory virus that requires additional practice expenses as seen this time, it would be available for use.”

The AMA also announced a second addition, CPT code 86413, that anticipates greater use of quantitative measurements of SARS-CoV-2 antibodies, as opposed to a qualitative assessment (positive/negative) provided by laboratory tests reported by other CPT codes.

For children with COVID-19, rates of hospitalization, ICU admission, and ventilator use were similar to those of children with influenza, but rates differed in other respects, according to results of a study published online Sept. 11 in JAMA Network Open.

As winter approaches, distinguishing patients with COVID-19 from those with influenza will become a problem. To assist with that, Xiaoyan Song, PhD, director of the office of infection control and epidemiology at Children’s National Hospital in Washington, D.C., and colleagues investigated commonalities and differences between the clinical symptoms of COVID-19 and influenza in children.

“Distinguishing COVID-19 from flu and other respiratory viral infections remains a challenge to clinicians. Although our study showed that patients with COVID-19 were more likely than patients with flu to report fever, gastrointestinal, and other clinical symptoms at the time of diagnosis, the two groups do have many overlapping clinical symptoms,” Dr. Song said. “Until future data show us otherwise, clinicians need to prepare for managing coinfections of COVID-19 with flu and/or other respiratory viral infections in the upcoming flu season.”

The retrospective cohort study included 315 children diagnosed with laboratory-confirmed COVID-19 between March 25 and May 15, 2020, and 1,402 children diagnosed with laboratory-confirmed seasonal influenza A or influenza B between Oct. 1, 2019, and June 6, 2020, at Children’s National Hospital. The investigation excluded asymptomatic patients who tested positive for COVID-19.

Patients with COVID-19 and patients with influenza were similar with respect to rates of hospitalization (17% vs. 21%; odds ratio, 0.8; 95% confidence interval, 0.6-1.1; P = .15), admission to the ICU (6% vs. 7%; OR, 0.8; 95% CI, 0.5-1.3; P = .42), and use of mechanical ventilation (3% vs. 2%; OR, 1.5; 95% CI, 0.9-2.6; P =.17).

The difference in the duration of ventilation for the two groups was not statistically significant. None of the patients who had COVID-19 or influenza B died, but two patients with influenza A did.

No patients had coinfections, which the researchers attribute to the mid-March shutdown of many schools, which they believe limited the spread of seasonal influenza.

Patients who were hospitalized with COVID-19 were older (median age, 9.7 years; range, 0.06-23.2 years) than those hospitalized with either type of influenza (median age, 4.2 years; range, 0.04-23.1). Patients older than 15 years made up 37% of patients with COVID-19 but only 6% of those with influenza.

Among patients hospitalized with COVID-19, 65% had at least one underlying medical condition, compared with 42% of those hospitalized for either type of influenza (OR, 2.6; 95% CI, 1.4-4.7; P = .002).

The most common underlying condition was neurologic problems from global developmental delay or seizures, identified in 11 patients (20%) hospitalized with COVID-19 and in 24 patients (8%) hospitalized with influenza (OR, 2.8; 95% CI, 1.3-6.2; P = .002). There was no significant difference between the two groups with respect to a history of asthma, cardiac disease, hematologic disease, and cancer.

For both groups, fever and cough were the most frequently reported symptoms at the time of diagnosis. However, more patients hospitalized with COVID-19 reported fever (76% vs. 55%; OR, 2.6; 95% CI, 1.4-5.1; P = 01), diarrhea or vomiting (26% vs. 12%; OR, 2.5; 95% CI, 1.2-5.0; P = .01), headache (11% vs. 3%; OR, 3.9; 95% CI, 1.3-11.5; P = .01), myalgia (22% vs. 7%; OR, 3.9; 95% CI, 1.8-8.5; P = .001), or chest pain (11% vs. 3%; OR, 3.9; 95% CI, 1.3-11.5; P = .01).

The researchers found no statistically significant differences between the two groups in rates of cough, congestion, sore throat, or shortness of breath.

Comparison of the symptom spectrum between COVID-19 and flu differed with respect to influenza type. More patients with COVID-19 reported fever, cough, diarrhea and vomiting, and myalgia than patients hospitalized with influenza A. But rates of fever, cough, diarrhea or vomiting, headache, or chest pain didn’t differ significantly in patients with COVID-19 and those with influenza B.

Larry K. Kociolek, MD, medical director of infection prevention and control at Ann and Robert H. Lurie Children’s Hospital of Chicago, noted the lower age of patients with flu. “Differentiating the two infections, which is difficult if not impossible based on symptoms alone, may have prognostic implications, depending on the age of the child. Because this study was performed outside peak influenza season, when coinfections would be less likely to occur, we must be vigilant about the potential clinical implications of influenza and SARS-CoV-2 coinfection this fall and winter.”

Clinicians will still have to use a combination of symptoms, examinations, and testing to distinguish the two diseases, said Aimee Sznewajs, MD, medical director of the pediatric hospital medicine department at Children’s Minnesota, Minneapolis. “We will continue to test for influenza and COVID-19 prior to hospitalizations and make decisions about whether to hospitalize based on other clinical factors, such as dehydration, oxygen requirement, and vital sign changes.”

Dr. Sznewajs stressed the importance of maintaining public health strategies, including “ensuring all children get the flu vaccine, encouraging mask wearing and hand hygiene, adequate testing to determine which virus is present, and other mitigation measures if the prevalence of COVID-19 is increasing in the community.”

Dr. Song reiterated those points, noting that clinicians need to make the most of the options they have. “Clinicians already have many great tools on hand. It is extremely important to get the flu vaccine now, especially for kids with underlying medical conditions. Diagnostic tests are available for both COVID-19 and flu. Antiviral treatment for flu is available. Judicious use of these tools will protect the health of providers, kids, and well-being at large.”

The authors noted several limitations for the study, including its retrospective design, that the data came from a single center, and that different platforms were used to detect the viruses.

Conventional chest x-rays combined with artificial intelligence (AI) can identify lung damage from COVID-19 and differentiate coronavirus patients from other patients, improving triage efforts, new research suggests.

The AI tool – developed by Jason Fleischer, PhD, and graduate student Mohammad Tariqul Islam, both from Princeton (N.J.) University – can distinguish COVID-19 patients from those with pneumonia or normal lung tissue with an accuracy of more than 95%.

“We were able to separate the COVID-19 patients with very high fidelity,” Dr. Fleischer said in an interview. “If you give me an x-ray now, I can say with very high confidence whether a patient has COVID-19.”

The diagnostic tool pinpoints patterns on x-ray images that are too subtle for even trained experts to notice. The precision of CT scanning is similar to that of the AI tool, but CT costs much more and has other disadvantages, said Dr. Fleischer, who presented his findings at the virtual European Respiratory Society International Congress 2020.

“CT is more expensive and uses higher doses of radiation,” he said. “Another big thing is that not everyone has tomography facilities – including a lot of rural places and developing countries – so you need something that’s on the spot.”

With machine learning, Dr. Fleischer analyzed 2,300 x-ray images: 1,018 “normal” images from patients who had neither pneumonia nor COVID-19, 1,011 from patients with pneumonia, and 271 from patients with COVID-19.

The AI tool uses a neural network to refine the number and type of lung features being tracked. A UMAP (Uniform Manifold Approximation and Projection) clustering algorithm then looks for similarities and differences in those images, he explained.

“We, as users, knew which type each x-ray was – normal, pneumonia positive, or COVID-19 positive – but the network did not,” he added.

Clinicians have observed two basic types of lung problems in COVID-19 patients: pneumonia that fills lung air sacs with fluid and dangerously low blood-oxygen levels despite nearly normal breathing patterns. Because treatment can vary according to type, it would be beneficial to quickly distinguish between them, Dr. Fleischer said.

The AI tool showed that there is a distinct difference in chest x-rays from pneumonia-positive patients and healthy people, he said. It also demonstrated two distinct clusters of COVID-19–positive chest x-rays: those that looked like pneumonia and those with a more normal presentation.

The fact that “the AI system recognizes something unique in chest x-rays from COVID-19–positive patients” indicates that the computer is able to identify visual markers for coronavirus, he explained. “We currently do not know what these markers are.”

Dr. Fleischer said his goal is not to replace physician decision-making, but to supplement it.

“I’m uncomfortable with having computers make the final decision,” he said. “They often have a narrow focus, whereas doctors have the big picture in mind.”

This AI tool is “very interesting,” especially in the context of expanding AI applications in various specialties, said Thierry Fumeaux, MD, from Nyon (Switzerland) Hospital. Some physicians currently disagree on whether a chest x-ray or CT scan is the better tool to help diagnose COVID-19.

“It seems better than the human eye and brain” to pinpoint COVID-19 lung damage, “so it’s very attractive as a technology,” Dr. Fumeaux said in an interview.

And AI can be used to supplement the efforts of busy and fatigued clinicians who might be stretched thin by large caseloads. “I cannot read 200 chest x-rays in a day, but a computer can do that in 2 minutes,” he said.

But Dr. Fumeaux offered a caveat: “Pattern recognition is promising, but at the moment I’m not aware of papers showing that, by using AI, you’re changing anything in the outcome of a patient.”

Ideally, Dr. Fleischer said he hopes that AI will soon be able to accurately indicate which treatments are most effective for individual COVID-19 patients. And the technology might eventually be used to help with treatment decisions for patients with asthma or chronic obstructive pulmonary disease, he noted.

But he needs more data before results indicate whether a COVID-19 patient would benefit from ventilator support, for example, and the tool can be used more widely. To contribute data or collaborate with Dr. Fleischer’s efforts, contact him.

“Machine learning is all about data, so you can find these correlations,” he said. “It would be nice to be able to use it to reassure a worried patient that their prognosis is good; to say that most of the people with symptoms like yours will be just fine.”

Dr. Fleischer and Dr. Fumeaux have declared no relevant financial relationships.

Conventional chest x-rays combined with artificial intelligence (AI) can identify lung damage from COVID-19 and differentiate coronavirus patients from other patients, improving triage efforts, new research suggests.

The AI tool – developed by Jason Fleischer, PhD, and graduate student Mohammad Tariqul Islam, both from Princeton (N.J.) University – can distinguish COVID-19 patients from those with pneumonia or normal lung tissue with an accuracy of more than 95%.

“We were able to separate the COVID-19 patients with very high fidelity,” Dr. Fleischer said in an interview. “If you give me an x-ray now, I can say with very high confidence whether a patient has COVID-19.”

The diagnostic tool pinpoints patterns on x-ray images that are too subtle for even trained experts to notice. The precision of CT scanning is similar to that of the AI tool, but CT costs much more and has other disadvantages, said Dr. Fleischer, who presented his findings at the virtual European Respiratory Society International Congress 2020.

“CT is more expensive and uses higher doses of radiation,” he said. “Another big thing is that not everyone has tomography facilities – including a lot of rural places and developing countries – so you need something that’s on the spot.”

With machine learning, Dr. Fleischer analyzed 2,300 x-ray images: 1,018 “normal” images from patients who had neither pneumonia nor COVID-19, 1,011 from patients with pneumonia, and 271 from patients with COVID-19.

Diagnoses of 12 common pediatric infectious diseases in a large pediatric primary care network declined significantly in the weeks after COVID-19 social distancing (SD) was enacted in Massachusetts, compared with the same time period in 2019, an analysis of EHR data has shown.

ArtMarie/E+

While declines in infectious disease transmission with SD are not surprising, “these data demonstrate the extent to which transmission of common pediatric infections can be altered when close contact with other children is eliminated,” Jonathan Hatoun, MD, MPH of the Pediatric Physicians’ Organization at Children’s in Brookline, Mass., and coauthors wrote in Pediatrics . “Notably, three of the studied diseases, namely, influenza, croup, and bronchiolitis, essentially disappeared with [social distancing].”

The researchers analyzed the weekly incidence of each diagnosis for similar calendar periods in 2019 and 2020. A pre-SD period was defined as week 1-9, starting on Jan. 1, and a post-SD period was defined as week 13-18. (The several-week gap represented an implementation period as social distancing was enacted in the state earlier in 2020, from a declared statewide state of emergency through school closures and stay-at-home advisories.)

To isolate the effect of widespread SD, they performed a “difference-in-differences regression analysis, with diagnosis count as a function of calendar year, time period (pre-SD versus post-SD) and the interaction between the two.” The Massachusetts pediatric network provides care for approximately 375,000 children in 100 locations around the state.

In their research brief, Dr. Hatoun and coauthors presented weekly rates expressed as diagnoses per 100,000 patients per day. The rate of bronchiolitis, for instance, was 18 and 8 in the pre- and post-SD–equivalent weeks of 2019, respectively, and 20 and 0.6 in the pre- and post-SD weeks of 2020. Their analysis showed the rate in the 2020 post-SD period to be 10 diagnoses per 100,000 patients per day lower than they would have expected based on the 2019 trend.

Rates of pneumonia, acute otitis media, and streptococcal pharyngitis were similarly 14, 85, and 31 diagnoses per 100,000 patients per day lower, respectively. The prevalence of each of the other conditions analyzed – the common cold, croup, gastroenteritis, nonstreptococcal pharyngitis, sinusitis, skin and soft tissue infections, and urinary tract infection (UTI) – also was significantly lower in the 2020 post-SD period than would be expected based on 2019 data (P < .001 for all diagnoses).
 

Putting things in perspective

“This study puts numbers to the sense that we have all had in pediatrics – that social distancing appears to have had a dramatic impact on the transmission of common childhood infectious diseases, especially other respiratory viral pathogens,” Audrey R. John, MD, PhD, chief of the division of pediatric infectious disease at Children’s Hospital of Philadelphia, said in an interview.

The authors acknowledged the possible role of families not seeking care, but said that a smaller decrease in diagnoses of UTI – generally not a contagious disease – “suggests that changes in care-seeking behavior had a relatively modest effect on the other observed declines.” (The rate of UTI for the pre- and post-SD periods was 3.3 and 3.7 per 100,000 patients per day in 2019, and 3.4 and 2.4 in 2020, for a difference in differences of –1.5).

In an accompanying editorial, David W. Kimberlin, MD and Erica C. Bjornstad, MD, PhD, MPH, of the University of Alabama at Birmingham, called the report “provocative” and wrote that similar observations of infections dropping during periods of isolation – namely, dramatic declines in influenza and other respiratory viruses in Seattle after a record snowstorm in 2019 – combined with findings from other modeling studies “suggest that the decline [reported in Boston] is indeed real” (Pediatrics 2020. doi: 10.1542/peds.2020-019232).

However, “we also now know that immunization rates for American children have plummeted since the onset of the SARS-CoV-2 pandemic [because of a] ... dramatic decrease in the use of health care during the first months of the pandemic,” they wrote. “Viewed through this lens,” the declines reported in Boston may reflect inflections going “undiagnosed and untreated.”

Ultimately, Dr. Kimberlin and Dr. Bjornstad said, “the verdict remains out.”

Dr. John said that she and others are “concerned about children not seeking care in a timely manner, and [concerned] that reductions in reported infections might be due to a lack of recognition rather than a lack of transmission.”

In Philadelphia, however, declines in admissions for asthma exacerbations, “which are often caused by respiratory viral infections, suggests that this may not be the case,” said Dr. John, who was asked to comment on the study.

In addition, she said, the Massachusetts data showing that UTI diagnoses “are nearly as common this year as in 2019” are “reassuring.”
 

Are there lessons for the future?

Coauthor Louis Vernacchio, MD, MSc, chief medical officer of the Pediatric Physicians’ Organization at Children’s network, said in an interview that beyond the pandemic, it’s likely that “more careful attention to proven infection control practices in daycares and schools could reduce the burden of common infectious diseases in children.”

Dr. John similarly sees a long-term value of quantifying the impact of social distancing. “We’ve always known [for instance] that bronchiolitis is the result of viral infection.” Findings like the Massachusetts data “will help us advise families who might be trying to protect their premature infants (at risk for severe bronchiolitis) through social distancing.”

The analysis covered both in-person and telemedicine encounters occurring on weekdays.

The authors of the research brief indicated they have no relevant financial disclosures and there was no external funding. The authors of the commentary also reported they have no relevant financial disclosures, and Dr. John said she had no relevant financial disclosures.

A new review offers fresh guidance to help stem the mental health toll of the COVID-19 pandemic on frontline clinicians.

Investigators gathered practice guidelines and resources from a wide range of health care organizations and professional societies to develop a conceptual framework of mental health support for health care professionals (HCPs) caring for COVID-19 patients.

An opportune moment

Coauthor Rebecca Margolis, DO, director of well-being in the division of medical education and faculty development, Children’s Hospital of Los Angeles, said that this is “an opportune moment to look at how we treat frontline providers in this country.”

Studies of previous pandemics have shown heightened distress in HCPs, even years after the pandemic, and the unique challenges posed by the COVID-19 pandemic surpass those of previous pandemics, Dr. Margolis said in an interview.

Dr. Schwartz, Dr. Margolis, and coauthors Uma Anand, PhD, LP, and Jina Sinskey, MD, met through the Collaborative for Healing and Renewal in Medicine network, a group of medical educators, leaders in academic medicine, experts in burnout research and interventions, and trainees working together to promote well-being among trainees and practicing physicians.

“We were brought together on a conference call in March, when things were particularly bad in New York, and started looking to see what resources we could get to frontline providers who were suffering. It was great to lean on each other and stand on the shoulders of colleagues in New York, who were the ones we learned from on these calls,” said Dr. Margolis.

The authors recommended addressing clinicians’ basic practical needs, including ensuring essentials like meals and transportation, establishing a “well-being area” within hospitals for staff to rest, and providing well-stocked living quarters so clinicians can safely quarantine from family, as well as personal protective equipment and child care.

Clinicians are often asked to “assume new professional roles to meet evolving needs” during a pandemic, which can increase stress. The authors recommended targeted training, assessment of clinician skills before redeployment to a new clinical role, and clear communication practices around redeployment.

Recognition from hospital and government leaders improves morale and supports clinicians’ ability to continue delivering care. Leadership should “leverage communication strategies to provide clinicians with up-to-date information and reassurance,” they wrote.
 

‘Uniquely isolated’

Dr. Margolis noted that clinicians “are uniquely isolated, especially those with children” because many parents do not want their children mingling with children of HCPs.

“My colleagues feel a sense of moral injury, putting their lives on the line at work, performing the most perilous job, and their kids can’t hang out with other kids, which just puts salt on the wound,” she said.

Additional sources of moral injury are deciding which patients should receive life support in the event of inadequate resources and bearing witness to, or enforcing, policies that lead to patients dying alone.

Leaders should encourage clinicians to “seek informal support from colleagues, managers, or chaplains” and to “provide rapid access to professional help,” the authors noted.

Furthermore, they contended that leaders should “proactively and routinely monitor the psychological well-being of their teams,” since guilt and shame often prevent clinicians from disclosing feelings of moral injury.

“Being provided with routine mental health support should be normalized and it should be part of the job – not only during COVID-19 but in general,” Dr. Schwartz said.
 

‘Battle buddies’

Dr. Margolis recommended the “battle buddy” model for mutual peer support.

Dr. Anand, a mental health clinician at Mayo Medical School, Rochester, Minn., elaborated.

A new review offers fresh guidance to help stem the mental health toll of the COVID-19 pandemic on frontline clinicians.

Investigators gathered practice guidelines and resources from a wide range of health care organizations and professional societies to develop a conceptual framework of mental health support for health care professionals (HCPs) caring for COVID-19 patients.

An opportune moment

Coauthor Rebecca Margolis, DO, director of well-being in the division of medical education and faculty development, Children’s Hospital of Los Angeles, said that this is “an opportune moment to look at how we treat frontline providers in this country.”

Studies of previous pandemics have shown heightened distress in HCPs, even years after the pandemic, and the unique challenges posed by the COVID-19 pandemic surpass those of previous pandemics, Dr. Margolis said in an interview.

Dr. Schwartz, Dr. Margolis, and coauthors Uma Anand, PhD, LP, and Jina Sinskey, MD, met through the Collaborative for Healing and Renewal in Medicine network, a group of medical educators, leaders in academic medicine, experts in burnout research and interventions, and trainees working together to promote well-being among trainees and practicing physicians.

“We were brought together on a conference call in March, when things were particularly bad in New York, and started looking to see what resources we could get to frontline providers who were suffering. It was great to lean on each other and stand on the shoulders of colleagues in New York, who were the ones we learned from on these calls,” said Dr. Margolis.

The authors recommended addressing clinicians’ basic practical needs, including ensuring essentials like meals and transportation, establishing a “well-being area” within hospitals for staff to rest, and providing well-stocked living quarters so clinicians can safely quarantine from family, as well as personal protective equipment and child care.

Clinicians are often asked to “assume new professional roles to meet evolving needs” during a pandemic, which can increase stress. The authors recommended targeted training, assessment of clinician skills before redeployment to a new clinical role, and clear communication practices around redeployment.

Recognition from hospital and government leaders improves morale and supports clinicians’ ability to continue delivering care. Leadership should “leverage communication strategies to provide clinicians with up-to-date information and reassurance,” they wrote.
 

‘Uniquely isolated’

Dr. Margolis noted that clinicians “are uniquely isolated, especially those with children” because many parents do not want their children mingling with children of HCPs.

“My colleagues feel a sense of moral injury, putting their lives on the line at work, performing the most perilous job, and their kids can’t hang out with other kids, which just puts salt on the wound,” she said.

Additional sources of moral injury are deciding which patients should receive life support in the event of inadequate resources and bearing witness to, or enforcing, policies that lead to patients dying alone.

Leaders should encourage clinicians to “seek informal support from colleagues, managers, or chaplains” and to “provide rapid access to professional help,” the authors noted.

Furthermore, they contended that leaders should “proactively and routinely monitor the psychological well-being of their teams,” since guilt and shame often prevent clinicians from disclosing feelings of moral injury.

“Being provided with routine mental health support should be normalized and it should be part of the job – not only during COVID-19 but in general,” Dr. Schwartz said.
 

‘Battle buddies’

Dr. Margolis recommended the “battle buddy” model for mutual peer support.

Dr. Anand, a mental health clinician at Mayo Medical School, Rochester, Minn., elaborated.

Niket Sonpal, MD, thought he’d heard most of the myths about wearing masks during the pandemic, but the recent claim from a patient was a new one for the New York City gastroenterologist.

The patient refused to wear a mask because she heard inhaling bad breath through a mask could be toxic. The woman said the rumor was circulating on Facebook. Sonpal calmly explained that breathing your own breath is not going to cause health problems, he said.

“There’s a lot of controversy on masks,” he said. “Unfortunately, it’s really just a lack of education and buy-in. Social media is the primary source of all this misinformation. These kinds of over-the-top hyperbole has basically led to a disbelief that masks are effective. The disbelief is hard to break up.”

As mask requirements have tightened amid the ongoing pandemic, debates about face coverings have emerged front and center, with a growing number of people opposing mask usage. So-called antimaskers dispute the benefits of wearing masks and many contend that face coverings decrease oxygen flow and can lead to illness. Sentiment against masks have led to protests nationwide, ignited public conflicts in some areas, and even generated lawsuits over mask mandates.

The issue presents an ongoing challenge for physicians as they strive to educate patients about the significance of masking against the flood of antimask messages on social media and beyond. Opposition to masks is particularly frustrating for health professionals who have witnessed patients, family, or friends become ill or die from the virus. Refusing to mask and failing to social distance have been linked to the rapid spread of the coronavirus and subsequent deaths.

“I have had colleagues pass away, and it’s extremely disheartening and frustrating to see science so easily disregarded,” Sonpal said. “Masks save lives and protect people and not wearing them is simply a lack of respect, not just for your fellow colleagues, but for a member of your species.”

Michael Rebresh, who helped create the antimask group Million Unmasked Patriots, says his group’s objections to masks are rational and reasonable. The group, which has more than 8,000 members, formed in response to guidance by Illinois state officials that children would only be allowed to return to school wearing a mask.

“Our objections are to the fact that masks on children in school have a greater propensity to make children sick from breathing in bacteria that forms on the inner layer of a mask worn for hours on end,” Rebresh said. “We have an objection to the increase of CO₂ intake and a decrease in oxygen flow for kids who need all the oxygen they can get during a learning environment. We recognized the masking of ourselves and kids for what it is: A political move to separate the two parties in our November election and define and create division between the two.”

Million Unmasked Patriots is one of dozens of antimask groups on social media platforms such as Facebook, Instagram, and TikTok. In July, Facebook suspended one such group, Unmasking America, which boasts 9,600 members, for posting repeated claims that face masks obstruct oxygen flow and have negative mental health effects.

Experts say the antiscience rhetoric is far from new. The antimask movement in many ways, shares similarities with that of the anti-vaccine movement, says Todd Wolynn, MD, a Pittsburgh pediatrician and cofounder of Shots Heard Round the World, an organization that defends vaccine advocates against coordinated online attacks by antivaxxers. Those espousing antimask views often relay similar or the same disinformation pushed by those with antivaccine views, Wolynn said.

“A lot of it is conspiracy-laden,” said Wolynn of the disinformation. “That Dr. [Anthony] Fauci somehow helped construct the pandemic and that it’s not real. That Bill Gates is funding the vaccine so he can inject people with microchips. All sorts of really out-there, ungrounded conspiracy theories. If you had Venn diagram of antimask and antivaxx, I would say there’s clearly overlap.”
 

Parallels between antimaskers, antivaxxers

Opponents to masks fall on a spectrum, explains Vineet Arora, MD, a hospitalist and associate chief medical officer–clinical learning environment at University of Chicago Medicine. People who believe conspiracy theories and push misinformation are on one end, she said. There are also those who generally don’t believe the seriousness of the pandemic, feel their risk is minimal, or doubt the benefits of masks.

The two trains of thought resemble the distinction among parents who are antivaccine and those who are simply “vaccine hesitant,” says Arora, who co-authored a recent article about masking and misinformation that addresses antivaccine attitudes.

“While the antimask sentiment gets a lot of attention, I think it’s important to highlight there’s a lot of vocal anti-mask sentiment since most people are supportive of masks,” she said. “There might be people sitting on the fence who are just unsure about wearing a mask. That’s understandable because the science and the communication has evolved. There was a lot of early mixed messages about masking. Anytime you have confusion about the science or the science is evolving, it’s easy to have misinformation and then have that take off as myth.”

Just as antivaxxers work to swing the opinion of the vaccine hesitant, antimaskers are vying with public health advocates for the support of the mask hesitant, she said. Creating doubt in public health authorities is one way they are gaining followers. Anti-maskers often question and scrutinize past messaging about masks by public health officials, claiming that because guidance on masks has changed over time, the science behind masks and current guidance can’t be trusted, Wolynn said. Similarly, antivaxxers frequently question past actions by public health officials, such as the Tuskegee Experiment (which began in 1932), to try to poke holes in the credibility of public health officials and their advice.

Both the antimask and antivaccine movements also tend to base their resistance on a personal liberties argument, adds Jacqueline Winfield Fincher, MD, president for the American College of Physicians and an internist based in Thomson, Georgia. Antimaskers contend they should be free to decide whether to wear face coverings and that rules requiring masks infringe upon their civil liberties. Similarly, antivaxxers argue they should be free to decide whether to vaccinate their children and contend vaccine mandates violate their personal liberties.

Taking a deeper look, fear and control are two likely drivers of antimasking and antivaccine attitudes, Fincher said. Those refusing to wear masks may feel they have no control over the pandemic or its impacts, but they can control how they respond to mask-wearing requirements, she said.

Antivaccine parents often want more control over their children’s healthcare and falsely believe that vaccines are injecting something harmful into their children or may lead to harmful reactions.

“It’s a control issue and a defense mechanism,” she said. “Some people may feel helpless to deal with the pandemic or believe since it is not affecting them or their family, that it is not real. ‘If I just deny it and I don’t acknowledge facts, I don’t have to worry about it or do anything about it, and therefore I will have more control over my day-to-day life.’”
 

Groups fueling each other

In some cases, antimask and antivaxx groups are joining forces or adopting dual causes.

In California for instance, longtime opponents to vaccines are now objecting to mask policies as similar infringement to their bodily autonomy. Demonstrations in Texas, Idaho, and Michigan against mask mandates and other COVID-19 requirements have drawn support from anti-vaccine activists and incorporated antivaccine propaganda.

In Illinois, Million Unmasked Patriots, formally the Million Unmasked March, has received widespread attention for protesting both masks for returning schoolchildren and a future COVID-19 vaccine requirement.

A July protest planned by the antimask group triggered a letter by Arora and 500 other healthcare professionals to Illinois lawmakers decrying the group’s views and urging the state to move forward with universal masking in schools.

“What’s happening is those who are distrustful of government and public health and science are joining together,” said Arora, who coauthored a piece about the problem on KevinMD.com. “It’s important to address both movements together because they can quickly feed off each other and build in momentum. At the heart of both is really this deep skepticism of science.”

Rebresh of Million Unmasked Patriots said most of his members are not opposed to all vaccines, but rather they are opposed to “untested vaccines.” The primary concern is the inability to research long-term effects of a COVID-19 vaccine before its approval, he said.

Rebresh disagrees with the antimask movement being compared with the antivaccine movement. The two groups are “motivated by different things and a different set of circumstances drive their opinions,” he said. However, Rebresh believes that potential harm resulting from “mass vaccinations” is a valid concern. For this reason, he and his wife chose for their children to receive their vaccinations individually over a series of weeks, rather than the “kiddie cocktail of vaccines,” at a single visit, he said.

Vaccine scientist Peter Hotez, MD, PhD, said the antivaccine movement appears to have grown stronger from the pandemic fueled by fresh conspiracies and new alliances. Antivaccine sentiment has been gaining steam over the last several years and collecting more allies from the far-right, said Hotez, dean for the National School of Tropical Medicine and codirector for the Texas Children’s Hospital Center for Vaccine Development.

“Now what you’re seeing is yet another expansion this year, with antivaccine groups, under the banner of ‘health freedom,’ campaigning against social distancing and wearing masks and contact tracing,” he said. “What was an antivaccine movement has now become a full-blown antiscience movement and an anti-public health movement. It’s causing a lot of damage and I believe costing a lot of American lives.”

Neil F. Johnson, PhD, who has studied the antivaccine movement and its social media proliferation during the pandemic, said online comments by antivaxxers frequently condemn mask usage and showcase memes making fun of masks.

“In those same narratives about opposing vaccines for COVID, we see a lot of discussion against masks,” said Johnson, a physics professor at George Washington University in Washington, D.C. “If you don’t believe in the official picture of COVID, you don’t believe the policies or the advice that’s given about COVID.”

An analysis by Johnson that examined 1,300 Facebook pages found that, while antivaxxers have fewer followers than provaccine pages, antivaccine pages are more numerous, faster growing, and are more often connected to unrelated, undecided pages. Conversely, pages that advocate the benefits of vaccinations and explain the science behind immunizations are largely disconnected from such undecided communities, according to the study, published May 13 in Nature.

The study suggests the antivaccine movement is making influential strides during the pandemic and connecting with people who are undecided, while public health advocates are not building the same bridges, Johnson said.

“I think it’s hugely dangerous, because I don’t know any other moment in science or in public health when there was so much uncertainty in something affecting everybody,” he said. “Every policy that will be coming, everything depends on people buying into the official message. Once you have the seeds of doubt, that’s a very difficult thing to overcome. It’s an unprecedented challenge.”
 

How physicians and clinicians can help

A more aggressive approach is necessary when it comes to taking down antiscience content on social media, says Hotez. Too often, misinformation and antiscience rhetoric is allowed to linger on popular sites such as Facebook and Amazon.

Wolynn agrees. On personal or business platforms, it’s crucial to ban, hide, and delete such comments as quickly as possible, he said. On public sites, purposeful disinformation should be immediately reported to the platform.

At the same time, Wolynn said it’s essential to support those who make sound, science-based comments in social media forums.

“If you see someone who is pushing accurate, evidence-based information, and they come under attack, they should be supported and defended and empowered,” Wolynn said. “Shots Heard Round the World is doing all of those things, including galvanizing and recruiting more people to help get their voices out there.”

Expanded visibility by physicians and scientists would greatly help counter the spread of antiscience sentiment, adds Hotez.

“Too often, antiscience movements are able to flourish because scientists and physicians are invisible,” he said. “They’re too focused on either clinical practices or in the case of physician scientists, on grants and papers and not enough attention to public engagement. We’re going to have to change that around. We need to hear more from scientists directly.”

To that end, Wolynn said health care professionals, including medical students and residents, need to have formal training in communications, media, and social media as part of their education – and more support from employers to engage through social media.

“That’s where the fight is,” Wolynn said. “You can be the best diagnostician, the best clinician. You can make the right diagnosis and prescribe the right medication, but if families don’t hear what you’re saying, you’re not going to be effective. If you can’t be on the platform where they’re being influenced, we’re losing the battle.”
 

Speaking to your mask-hesitant patients

Concentrating on those who are uncertain about masks is particularly key for physicians and public health advocates as the pandemic continues, says Arora.

“It’s important for us to focus on the mask-hesitant who often don’t get the attention they need,” she said.

She suggests bringing up the subject of masks with patients during visits, asking about mask usage, discussing rumors they’ve heard, and emphasizing why masks are important. Be a role model by wearing a mask in your community and on social media, she added.

Some patients have real concerns about not being able to breathe through masks or anxiety disorders that can be aggravated even by the thought of wearing a mask, noted Susan R. Bailey, MD, president for the American Medical Association. Bailey, an immunologist, recently counseled a patient with a deviated nasal septum in addition to a panic disorder who was worried about wearing a mask, she said. Bailey listened to the patient’s concerns, discussed his health conditions, and proposed an alternative face covering that might make him more comfortable.

“Every patient is different,” Bailey said. “It’s important for us to remember that each person who is reluctant to wear a mask has their own reasons. It’s important for us to express some empathy – to agree with them, yes, masks are hot and inconvenient – and help understand their questions, which you may be able to answer to their satisfaction. There are patients that have legitimate questions and a physician caring about how they feel, can make all the difference.”

Physicians can also get involved with the AMA’s #MaskUp campaign, an effort to normalize mask wearing and debunk myths associated with masks. The campaign includes social media materials, slogans doctors can tweet, and profile pictures they can use on social media. The campaign’s toolkit includes images, videos, and information that physicians can share with patients and the public.

Enforcing strong mask policies at your practice and ensuring all staff are modeling appropriate mask behavior is also important, adds Fincher of the ACP. The college recently issued a policy supporting mask usage in community settings.

If a patient conveys an antimask belief, Fincher suggests not directly challenging the person’s views, but listening to them and offering objective data, discussing the science behind masks, and directing them to credible sources.

“Doctors are used to this. We recommend a lot of things to patients that they don’t want to do,” Fincher said. “If a patient feels attacked, they act defensively. But if you base your explanation in more objective terms with data, numbers, and personalize the risks and benefits of a vaccine, a healthy change in behavior, or a medication, then patients are more likely to hear your concerns and do the right thing. Having a long-term relationship with a trusted physician makes all of these issues much easier to discuss and to implement the best plan for the individual patient.”

“In those same narratives about opposing vaccines for COVID, we see a lot of discussion against masks,” said Johnson, a physics professor at George Washington University in Washington, D.C. “If you don’t believe in the official picture of COVID, you don’t believe the policies or the advice that’s given about COVID.”

An analysis by Johnson that examined 1,300 Facebook pages found that, while antivaxxers have fewer followers than provaccine pages, antivaccine pages are more numerous, faster growing, and are more often connected to unrelated, undecided pages. Conversely, pages that advocate the benefits of vaccinations and explain the science behind immunizations are largely disconnected from such undecided communities, according to the study, published May 13 in Nature.

The study suggests the antivaccine movement is making influential strides during the pandemic and connecting with people who are undecided, while public health advocates are not building the same bridges, Johnson said.

“I think it’s hugely dangerous, because I don’t know any other moment in science or in public health when there was so much uncertainty in something affecting everybody,” he said. “Every policy that will be coming, everything depends on people buying into the official message. Once you have the seeds of doubt, that’s a very difficult thing to overcome. It’s an unprecedented challenge.”
 

How physicians and clinicians can help

A more aggressive approach is necessary when it comes to taking down antiscience content on social media, says Hotez. Too often, misinformation and antiscience rhetoric is allowed to linger on popular sites such as Facebook and Amazon.

Wolynn agrees. On personal or business platforms, it’s crucial to ban, hide, and delete such comments as quickly as possible, he said. On public sites, purposeful disinformation should be immediately reported to the platform.

At the same time, Wolynn said it’s essential to support those who make sound, science-based comments in social media forums.

“If you see someone who is pushing accurate, evidence-based information, and they come under attack, they should be supported and defended and empowered,” Wolynn said. “Shots Heard Round the World is doing all of those things, including galvanizing and recruiting more people to help get their voices out there.”

Expanded visibility by physicians and scientists would greatly help counter the spread of antiscience sentiment, adds Hotez.

“Too often, antiscience movements are able to flourish because scientists and physicians are invisible,” he said. “They’re too focused on either clinical practices or in the case of physician scientists, on grants and papers and not enough attention to public engagement. We’re going to have to change that around. We need to hear more from scientists directly.”

To that end, Wolynn said health care professionals, including medical students and residents, need to have formal training in communications, media, and social media as part of their education – and more support from employers to engage through social media.

“That’s where the fight is,” Wolynn said. “You can be the best diagnostician, the best clinician. You can make the right diagnosis and prescribe the right medication, but if families don’t hear what you’re saying, you’re not going to be effective. If you can’t be on the platform where they’re being influenced, we’re losing the battle.”
 

Speaking to your mask-hesitant patients

Concentrating on those who are uncertain about masks is particularly key for physicians and public health advocates as the pandemic continues, says Arora.

“It’s important for us to focus on the mask-hesitant who often don’t get the attention they need,” she said.

She suggests bringing up the subject of masks with patients during visits, asking about mask usage, discussing rumors they’ve heard, and emphasizing why masks are important. Be a role model by wearing a mask in your community and on social media, she added.

Some patients have real concerns about not being able to breathe through masks or anxiety disorders that can be aggravated even by the thought of wearing a mask, noted Susan R. Bailey, MD, president for the American Medical Association. Bailey, an immunologist, recently counseled a patient with a deviated nasal septum in addition to a panic disorder who was worried about wearing a mask, she said. Bailey listened to the patient’s concerns, discussed his health conditions, and proposed an alternative face covering that might make him more comfortable.

“Every patient is different,” Bailey said. “It’s important for us to remember that each person who is reluctant to wear a mask has their own reasons. It’s important for us to express some empathy – to agree with them, yes, masks are hot and inconvenient – and help understand their questions, which you may be able to answer to their satisfaction. There are patients that have legitimate questions and a physician caring about how they feel, can make all the difference.”

Physicians can also get involved with the AMA’s #MaskUp campaign, an effort to normalize mask wearing and debunk myths associated with masks. The campaign includes social media materials, slogans doctors can tweet, and profile pictures they can use on social media. The campaign’s toolkit includes images, videos, and information that physicians can share with patients and the public.

Enforcing strong mask policies at your practice and ensuring all staff are modeling appropriate mask behavior is also important, adds Fincher of the ACP. The college recently issued a policy supporting mask usage in community settings.

If a patient conveys an antimask belief, Fincher suggests not directly challenging the person’s views, but listening to them and offering objective data, discussing the science behind masks, and directing them to credible sources.

“Doctors are used to this. We recommend a lot of things to patients that they don’t want to do,” Fincher said. “If a patient feels attacked, they act defensively. But if you base your explanation in more objective terms with data, numbers, and personalize the risks and benefits of a vaccine, a healthy change in behavior, or a medication, then patients are more likely to hear your concerns and do the right thing. Having a long-term relationship with a trusted physician makes all of these issues much easier to discuss and to implement the best plan for the individual patient.”

Niket Sonpal, MD, thought he’d heard most of the myths about wearing masks during the pandemic, but the recent claim from a patient was a new one for the New York City gastroenterologist.

The patient refused to wear a mask because she heard inhaling bad breath through a mask could be toxic. The woman said the rumor was circulating on Facebook. Sonpal calmly explained that breathing your own breath is not going to cause health problems, he said.

“There’s a lot of controversy on masks,” he said. “Unfortunately, it’s really just a lack of education and buy-in. Social media is the primary source of all this misinformation. These kinds of over-the-top hyperbole has basically led to a disbelief that masks are effective. The disbelief is hard to break up.”

As mask requirements have tightened amid the ongoing pandemic, debates about face coverings have emerged front and center, with a growing number of people opposing mask usage. So-called antimaskers dispute the benefits of wearing masks and many contend that face coverings decrease oxygen flow and can lead to illness. Sentiment against masks have led to protests nationwide, ignited public conflicts in some areas, and even generated lawsuits over mask mandates.

The issue presents an ongoing challenge for physicians as they strive to educate patients about the significance of masking against the flood of antimask messages on social media and beyond. Opposition to masks is particularly frustrating for health professionals who have witnessed patients, family, or friends become ill or die from the virus. Refusing to mask and failing to social distance have been linked to the rapid spread of the coronavirus and subsequent deaths.

“I have had colleagues pass away, and it’s extremely disheartening and frustrating to see science so easily disregarded,” Sonpal said. “Masks save lives and protect people and not wearing them is simply a lack of respect, not just for your fellow colleagues, but for a member of your species.”

Michael Rebresh, who helped create the antimask group Million Unmasked Patriots, says his group’s objections to masks are rational and reasonable. The group, which has more than 8,000 members, formed in response to guidance by Illinois state officials that children would only be allowed to return to school wearing a mask.

“Our objections are to the fact that masks on children in school have a greater propensity to make children sick from breathing in bacteria that forms on the inner layer of a mask worn for hours on end,” Rebresh said. “We have an objection to the increase of CO₂ intake and a decrease in oxygen flow for kids who need all the oxygen they can get during a learning environment. We recognized the masking of ourselves and kids for what it is: A political move to separate the two parties in our November election and define and create division between the two.”

Million Unmasked Patriots is one of dozens of antimask groups on social media platforms such as Facebook, Instagram, and TikTok. In July, Facebook suspended one such group, Unmasking America, which boasts 9,600 members, for posting repeated claims that face masks obstruct oxygen flow and have negative mental health effects.

Experts say the antiscience rhetoric is far from new. The antimask movement in many ways, shares similarities with that of the anti-vaccine movement, says Todd Wolynn, MD, a Pittsburgh pediatrician and cofounder of Shots Heard Round the World, an organization that defends vaccine advocates against coordinated online attacks by antivaxxers. Those espousing antimask views often relay similar or the same disinformation pushed by those with antivaccine views, Wolynn said.

“A lot of it is conspiracy-laden,” said Wolynn of the disinformation. “That Dr. [Anthony] Fauci somehow helped construct the pandemic and that it’s not real. That Bill Gates is funding the vaccine so he can inject people with microchips. All sorts of really out-there, ungrounded conspiracy theories. If you had Venn diagram of antimask and antivaxx, I would say there’s clearly overlap.”
 

Parallels between antimaskers, antivaxxers

Opponents to masks fall on a spectrum, explains Vineet Arora, MD, a hospitalist and associate chief medical officer–clinical learning environment at University of Chicago Medicine. People who believe conspiracy theories and push misinformation are on one end, she said. There are also those who generally don’t believe the seriousness of the pandemic, feel their risk is minimal, or doubt the benefits of masks.

The two trains of thought resemble the distinction among parents who are antivaccine and those who are simply “vaccine hesitant,” says Arora, who co-authored a recent article about masking and misinformation that addresses antivaccine attitudes.

“While the antimask sentiment gets a lot of attention, I think it’s important to highlight there’s a lot of vocal anti-mask sentiment since most people are supportive of masks,” she said. “There might be people sitting on the fence who are just unsure about wearing a mask. That’s understandable because the science and the communication has evolved. There was a lot of early mixed messages about masking. Anytime you have confusion about the science or the science is evolving, it’s easy to have misinformation and then have that take off as myth.”

Just as antivaxxers work to swing the opinion of the vaccine hesitant, antimaskers are vying with public health advocates for the support of the mask hesitant, she said. Creating doubt in public health authorities is one way they are gaining followers. Anti-maskers often question and scrutinize past messaging about masks by public health officials, claiming that because guidance on masks has changed over time, the science behind masks and current guidance can’t be trusted, Wolynn said. Similarly, antivaxxers frequently question past actions by public health officials, such as the Tuskegee Experiment (which began in 1932), to try to poke holes in the credibility of public health officials and their advice.

Both the antimask and antivaccine movements also tend to base their resistance on a personal liberties argument, adds Jacqueline Winfield Fincher, MD, president for the American College of Physicians and an internist based in Thomson, Georgia. Antimaskers contend they should be free to decide whether to wear face coverings and that rules requiring masks infringe upon their civil liberties. Similarly, antivaxxers argue they should be free to decide whether to vaccinate their children and contend vaccine mandates violate their personal liberties.

Taking a deeper look, fear and control are two likely drivers of antimasking and antivaccine attitudes, Fincher said. Those refusing to wear masks may feel they have no control over the pandemic or its impacts, but they can control how they respond to mask-wearing requirements, she said.

Antivaccine parents often want more control over their children’s healthcare and falsely believe that vaccines are injecting something harmful into their children or may lead to harmful reactions.

“It’s a control issue and a defense mechanism,” she said. “Some people may feel helpless to deal with the pandemic or believe since it is not affecting them or their family, that it is not real. ‘If I just deny it and I don’t acknowledge facts, I don’t have to worry about it or do anything about it, and therefore I will have more control over my day-to-day life.’”
 

Groups fueling each other

In some cases, antimask and antivaxx groups are joining forces or adopting dual causes.

In California for instance, longtime opponents to vaccines are now objecting to mask policies as similar infringement to their bodily autonomy. Demonstrations in Texas, Idaho, and Michigan against mask mandates and other COVID-19 requirements have drawn support from anti-vaccine activists and incorporated antivaccine propaganda.

In Illinois, Million Unmasked Patriots, formally the Million Unmasked March, has received widespread attention for protesting both masks for returning schoolchildren and a future COVID-19 vaccine requirement.

A July protest planned by the antimask group triggered a letter by Arora and 500 other healthcare professionals to Illinois lawmakers decrying the group’s views and urging the state to move forward with universal masking in schools.

“What’s happening is those who are distrustful of government and public health and science are joining together,” said Arora, who coauthored a piece about the problem on KevinMD.com. “It’s important to address both movements together because they can quickly feed off each other and build in momentum. At the heart of both is really this deep skepticism of science.”

Rebresh of Million Unmasked Patriots said most of his members are not opposed to all vaccines, but rather they are opposed to “untested vaccines.” The primary concern is the inability to research long-term effects of a COVID-19 vaccine before its approval, he said.

Rebresh disagrees with the antimask movement being compared with the antivaccine movement. The two groups are “motivated by different things and a different set of circumstances drive their opinions,” he said. However, Rebresh believes that potential harm resulting from “mass vaccinations” is a valid concern. For this reason, he and his wife chose for their children to receive their vaccinations individually over a series of weeks, rather than the “kiddie cocktail of vaccines,” at a single visit, he said.

Vaccine scientist Peter Hotez, MD, PhD, said the antivaccine movement appears to have grown stronger from the pandemic fueled by fresh conspiracies and new alliances. Antivaccine sentiment has been gaining steam over the last several years and collecting more allies from the far-right, said Hotez, dean for the National School of Tropical Medicine and codirector for the Texas Children’s Hospital Center for Vaccine Development.

“Now what you’re seeing is yet another expansion this year, with antivaccine groups, under the banner of ‘health freedom,’ campaigning against social distancing and wearing masks and contact tracing,” he said. “What was an antivaccine movement has now become a full-blown antiscience movement and an anti-public health movement. It’s causing a lot of damage and I believe costing a lot of American lives.”

Neil F. Johnson, PhD, who has studied the antivaccine movement and its social media proliferation during the pandemic, said online comments by antivaxxers frequently condemn mask usage and showcase memes making fun of masks.

“In those same narratives about opposing vaccines for COVID, we see a lot of discussion against masks,” said Johnson, a physics professor at George Washington University in Washington, D.C. “If you don’t believe in the official picture of COVID, you don’t believe the policies or the advice that’s given about COVID.”

When establishing a treatment plan for patients with melasma, counseling them about realistic expectations is key.

“It’s important that they understand that this is a chronic condition, so it does require long-term maintenance therapy,” Arisa E. Ortiz, MD, said at the virtual annual Masters of Aesthetics Symposium. “We can improve melasma, but it’s difficult to cure melasma.”

While hydroquinone and other bleaching agents are typical treatment mainstays, chemical peels with glycolic acid, trichloroacetic acid, and salicylic acid can benefit some individuals. “For chemical peels, I really like glycolic acid peels because there is no downtime; it peels at the microscopic level,” said Dr. Ortiz, who is director of laser and cosmetic dermatology at the University of California, San Diego. “This is something they may need to repeat monthly, and having a week of peeling may be difficult to go through every month.”

Other common melasma treatments include lasers, intense pulsed light (IPL), and oral medications. “I personally am not impressed with microdermabrasion for melasma, so I don’t use that very much,” she said. “With laser treatment, you want to make sure you’re using low-energy lasers so that it doesn’t exacerbate or make them relapse or rebound.”

While hydroquinone is a mainstay of therapy, “you can’t use it chronically because of the risk of ochronosis (permanent darkening), so you do need to take drug holidays,” Dr. Ortiz said. “During those drug holidays, you want to make sure patients have a nonhydroquinone bleaching agent so that they don’t flare.” Options include lignin peroxidase, oligopeptide, Lytera, Melaplex, 4-n-butylresorcinol, Cysteamine cream, tranexamic acid, and oral antioxidants.

In a study sponsored by SkinMedica, investigators conducted a randomized, double-blind, half-face study in females with moderate to severe facial hyperpigmentation to assess the efficacy and tolerability of three new skin brightener formulations containing SMA-432, a prostaglandin E₂ inhibitor, compared with topical 4% hydroquinone (J Drugs Dermatol 2012 Dec;11[12]:1478-82). They found that the nonhydroquinone skin formulations were better tolerated and were just as effective as 4% hydroquinone.

In a separate unpublished study of 22 females, investigators assessed the efficacy of the U.SK Advanced Defense Booster, which contains ferulic acid, maslinic acid, peptides, and olive leaf extract. They observed that 98% of patients saw improvement after 28 days of treatment.

When it comes to using lasers for melasma treatment, low-energy devices provide the best outcomes. “I prefer using something like the 1927-nm fractional diode lasers at 3.75% density, really low densities because there’s less risk for rebound,” Dr. Ortiz said. “They also enhance skin permeability for the use of topicals.”

In an observational study of 27 female patients with refractory melasma, Arielle Kauvar, MD, director of New York Laser & Skin Care, combined microdermabrasion with the Q-switched Nd:YAG (Lasers in Surgery and Medicine 2012; 44:117-24). “The settings she used were very low fluence, so there was no clinical endpoint or no whitening,” Dr. Ortiz said. Specifically, she used a laser at 1.6-2 J/cm² with a 5- or 6-mm spot size immediately following microdermabrasion for 4 weeks. “She got a good improvement using a skin care regimen of sunscreen, hydroquinone, and tretinoin or vitamin C,” she said. “Remission lasted at least 6 months.”

In a study presented at the 2019 annual meeting of the America Society for Laser Medicine and Surgery, Dr. Ortiz and Tanya Greywal, MD, of the University of California, San Diego, used three passes of the 10764-nm Nd:YAG laser to treat 10 subjects with melasma skin types 2-5. The device has a 650-microsecond pulse duration, a 6-mm spot size, and an energy mode of 11-14 J/cm³. “There was no downtime with these patients, and they saw a mean improvement of 26%-50% as early as 3 weeks,” she said. “Patients did require multiple treatments to see adequate resolution, but no anesthesia or numbing cream was required. This is a good option for patients who need chronic maintenance treatment.”

Topicals also play a key role following the laser treatment of melasma. Dr. Ortiz characterized clobetasol as “kind of like the magic ointment.” She uses one application immediately post procedure “whenever I’m worried about a patient having postinflammatory hyperpigmentation or if I don’t want melasma patients to rebound. It can help reduce swelling and inflammation to decrease the risk of postinflammatory hyperpigmentation.”

Researchers have discovered that there is a vascular component to melasma. Paul M. Friedman, MD, of the Dermatology and Laser Surgery Center, Houston, and his colleagues used spectrocolorimetry to detect an underlying prominent vascular component in 11 patients with melasma (Lasers Surg Med 2017 Jan;49[1]:20-6). They determined that melasma lesions exhibiting subtle or subclinical telangiectatic erythema may be improved by combined vascular-targeted laser therapy together with fractional low-powered diode laser therapy. “A parallel improvement in telangiectatic erythema suggests a relationship between the underlying vasculature and hyperpigmentation,” said Dr. Ortiz, who was not affiliated with the study. “So, patients who have a vascular component to their melasma actually can get improved efficacy.”

Another strategy for melasma patients involves oral treatment with Polypodium leucotomos extract (PLE), a fern from the Polypodiaceae family with antioxidant properties that has been shown to be photoprotective against UVA and UVB radiation. “I like to think of it as an internal sunscreen,” Dr. Ortiz said. “It does not replace your external sunscreen, but it adds extra protection. It has been shown to significantly reduce the severity of sunburn and decrease the risk of UV radiation–induced skin cancer, as well as prevent skin aging.” The purported mechanism of action includes decreasing UV-mediated oxidative damage to DNA, enhancing the activity of endogenous antioxidant systems, increasing the minimal erythema dose, blocking UV radiation–induced cyclooxygenase-2 expression, reducing UV-induced immune suppression, and promoting p53 suppressor gene expression.

In a pilot placebo-controlled study of melasma patients on their normal regimen of hydroquinone and sunscreen, 40 Asian patients with melasma were randomized to receive either oral PLE supplementation or placebo for 12 weeks (J Clin Aesthet Dermatol 2018 Mar;11[3]:14-9). They found that PLE significantly improved and accelerated the outcome reached with hydroquinone and sunscreen from the first month of treatment, compared with placebo.

Dr. Ortiz next discussed the role of oral tranexamic acid, an antifibrinolytic, procoagulant agent that is approved by the Food and Drug Administration for the treatment of menorrhagia and for prevention of hemorrhage in patients with hemophilia undergoing tooth extractions. “It is a synthetic lysine derivative that inhibits plasminogen activation by blocking lysine-binding sites on the plasminogen molecule, and it’s a game changer for melasma treatment,” she said. “One of the side effects is that it inhibits melanogenesis and neovascularization. It’s been effective for melasma, but its use is limited by the risk for thromboembolism. It’s a slight increased risk, something patients should be aware of, but not something that should scare us away from prescribing it.”

In a study of 561 patients with melasma, 90% improved after a median treatment duration of 4 months, and only 7% had side effects (J Am Acad Dermatol 2016;75:385-92). The most common side effects were abdominal bloating and pain. One patient developed a DVT during treatment, but that person was found to have a protein S deficiency.

The daily dosing of tranexamic acid for menorrhagia is 3,900 mg daily, while the dose for melasma has ranged from 500 mg-1,500 mg per day, Dr. Ortiz said. It’s available as a 650-mg pill in the United States. “I prescribe 325 mg twice a day, but studies have shown that 650 mg once a day is just as effective,” she said.

Prior to prescribing tranexamic acid, Dr. Ortiz does not order labs, but she performs an extensive history of present illness. She does not prescribe it in patients with an increased risk of clotting, including people who smoke and those who take oral contraceptives or are on hormone supplementation. Use is also contraindicated in people with a current malignancy, those with a history of stroke or DVT, and those who have any clotting disorder.

She concluded her presentation by noting that she favors a combination approach to treating melasma patients that starts with a broad spectrum sunscreen and PLE. “For bleaching, I like to use 12% hydroquinone with 6% kojic acid in VersaBase,” she said. “Once I get them in better control, then I switch them to 4% hydroquinone for maintenance. I use glycolic peels, low-energy lasers, and tranexamic acid if the melasma is severe, and they have no contraindications. A combination approach really achieves the best results, and counseling is key.”

Dr. Ortiz disclosed having financial relationships with numerous pharmaceutical and device companies. She is also cochair of MOA.

The device has a 650-microsecond pulse duration, a 6-mm spot size, and an energy mode of 11-14 J/cm³. “There was no downtime with these patients, and they saw a mean improvement of 26%-50% as early as 3 weeks,” she said. “Patients did require multiple treatments to see adequate resolution, but no anesthesia or numbing cream was required. This is a good option for patients who need chronic maintenance treatment.”

Topicals also play a key role following the laser treatment of melasma. Dr. Ortiz characterized clobetasol as “kind of like the magic ointment.” She uses one application immediately post procedure “whenever I’m worried about a patient having postinflammatory hyperpigmentation or if I don’t want melasma patients to rebound. It can help reduce swelling and inflammation to decrease the risk of postinflammatory hyperpigmentation.”

Researchers have discovered that there is a vascular component to melasma. Paul M. Friedman, MD, of the Dermatology and Laser Surgery Center, Houston, and his colleagues used spectrocolorimetry to detect an underlying prominent vascular component in 11 patients with melasma (Lasers Surg Med 2017 Jan;49[1]:20-6). They determined that melasma lesions exhibiting subtle or subclinical telangiectatic erythema may be improved by combined vascular-targeted laser therapy together with fractional low-powered diode laser therapy. “A parallel improvement in telangiectatic erythema suggests a relationship between the underlying vasculature and hyperpigmentation,” said Dr. Ortiz, who was not affiliated with the study. “So, patients who have a vascular component to their melasma actually can get improved efficacy.”

Another strategy for melasma patients involves oral treatment with Polypodium leucotomos extract (PLE), a fern from the Polypodiaceae family with antioxidant properties that has been shown to be photoprotective against UVA and UVB radiation. “I like to think of it as an internal sunscreen,” Dr. Ortiz said. “It does not replace your external sunscreen, but it adds extra protection. It has been shown to significantly reduce the severity of sunburn and decrease the risk of UV radiation–induced skin cancer, as well as prevent skin aging.” The purported mechanism of action includes decreasing UV-mediated oxidative damage to DNA, enhancing the activity of endogenous antioxidant systems, increasing the minimal erythema dose, blocking UV radiation–induced cyclooxygenase-2 expression, reducing UV-induced immune suppression, and promoting p53 suppressor gene expression.

In a pilot placebo-controlled study of melasma patients on their normal regimen of hydroquinone and sunscreen, 40 Asian patients with melasma were randomized to receive either oral PLE supplementation or placebo for 12 weeks (J Clin Aesthet Dermatol 2018 Mar;11[3]:14-9). They found that PLE significantly improved and accelerated the outcome reached with hydroquinone and sunscreen from the first month of treatment, compared with placebo.

Dr. Ortiz next discussed the role of oral tranexamic acid, an antifibrinolytic, procoagulant agent that is approved by the Food and Drug Administration for the treatment of menorrhagia and for prevention of hemorrhage in patients with hemophilia undergoing tooth extractions. “It is a synthetic lysine derivative that inhibits plasminogen activation by blocking lysine-binding sites on the plasminogen molecule, and it’s a game changer for melasma treatment,” she said. “One of the side effects is that it inhibits melanogenesis and neovascularization. It’s been effective for melasma, but its use is limited by the risk for thromboembolism. It’s a slight increased risk, something patients should be aware of, but not something that should scare us away from prescribing it.”

In a study of 561 patients with melasma, 90% improved after a median treatment duration of 4 months, and only 7% had side effects (J Am Acad Dermatol 2016;75:385-92). The most common side effects were abdominal bloating and pain. One patient developed a DVT during treatment, but that person was found to have a protein S deficiency.

The daily dosing of tranexamic acid for menorrhagia is 3,900 mg daily, while the dose for melasma has ranged from 500 mg-1,500 mg per day, Dr. Ortiz said. It’s available as a 650-mg pill in the United States. “I prescribe 325 mg twice a day, but studies have shown that 650 mg once a day is just as effective,” she said.

Prior to prescribing tranexamic acid, Dr. Ortiz does not order labs, but she performs an extensive history of present illness. She does not prescribe it in patients with an increased risk of clotting, including people who smoke and those who take oral contraceptives or are on hormone supplementation. Use is also contraindicated in people with a current malignancy, those with a history of stroke or DVT, and those who have any clotting disorder.

She concluded her presentation by noting that she favors a combination approach to treating melasma patients that starts with a broad spectrum sunscreen and PLE. “For bleaching, I like to use 12% hydroquinone with 6% kojic acid in VersaBase,” she said. “Once I get them in better control, then I switch them to 4% hydroquinone for maintenance. I use glycolic peels, low-energy lasers, and tranexamic acid if the melasma is severe, and they have no contraindications. A combination approach really achieves the best results, and counseling is key.”

When establishing a treatment plan for patients with melasma, counseling them about realistic expectations is key.

“It’s important that they understand that this is a chronic condition, so it does require long-term maintenance therapy,” Arisa E. Ortiz, MD, said at the virtual annual Masters of Aesthetics Symposium. “We can improve melasma, but it’s difficult to cure melasma.”

While hydroquinone and other bleaching agents are typical treatment mainstays, chemical peels with glycolic acid, trichloroacetic acid, and salicylic acid can benefit some individuals. “For chemical peels, I really like glycolic acid peels because there is no downtime; it peels at the microscopic level,” said Dr. Ortiz, who is director of laser and cosmetic dermatology at the University of California, San Diego. “This is something they may need to repeat monthly, and having a week of peeling may be difficult to go through every month.”

Other common melasma treatments include lasers, intense pulsed light (IPL), and oral medications. “I personally am not impressed with microdermabrasion for melasma, so I don’t use that very much,” she said. “With laser treatment, you want to make sure you’re using low-energy lasers so that it doesn’t exacerbate or make them relapse or rebound.”

While hydroquinone is a mainstay of therapy, “you can’t use it chronically because of the risk of ochronosis (permanent darkening), so you do need to take drug holidays,” Dr. Ortiz said. “During those drug holidays, you want to make sure patients have a nonhydroquinone bleaching agent so that they don’t flare.” Options include lignin peroxidase, oligopeptide, Lytera, Melaplex, 4-n-butylresorcinol, Cysteamine cream, tranexamic acid, and oral antioxidants.

In a study sponsored by SkinMedica, investigators conducted a randomized, double-blind, half-face study in females with moderate to severe facial hyperpigmentation to assess the efficacy and tolerability of three new skin brightener formulations containing SMA-432, a prostaglandin E₂ inhibitor, compared with topical 4% hydroquinone (J Drugs Dermatol 2012 Dec;11[12]:1478-82). They found that the nonhydroquinone skin formulations were better tolerated and were just as effective as 4% hydroquinone.

In a separate unpublished study of 22 females, investigators assessed the efficacy of the U.SK Advanced Defense Booster, which contains ferulic acid, maslinic acid, peptides, and olive leaf extract. They observed that 98% of patients saw improvement after 28 days of treatment.

When it comes to using lasers for melasma treatment, low-energy devices provide the best outcomes. “I prefer using something like the 1927-nm fractional diode lasers at 3.75% density, really low densities because there’s less risk for rebound,” Dr. Ortiz said. “They also enhance skin permeability for the use of topicals.”

In an observational study of 27 female patients with refractory melasma, Arielle Kauvar, MD, director of New York Laser & Skin Care, combined microdermabrasion with the Q-switched Nd:YAG (Lasers in Surgery and Medicine 2012; 44:117-24). “The settings she used were very low fluence, so there was no clinical endpoint or no whitening,” Dr. Ortiz said. Specifically, she used a laser at 1.6-2 J/cm² with a 5- or 6-mm spot size immediately following microdermabrasion for 4 weeks. “She got a good improvement using a skin care regimen of sunscreen, hydroquinone, and tretinoin or vitamin C,” she said. “Remission lasted at least 6 months.”

Aquagenic wrinkling of the palms (AWP) is a condition characterized by excessive wrinkling and sudden appearance or aggravation of white papules and plaques localized to the palms upon exposure to water. This eruption can be accompanied by a mild burning or tingling sensation, which will subside with the rest of the symptoms in minutes to hours after drying.¹

AWP is most frequently associated with cystic fibrosis (CF).² It can be observed in up to 80% of CF patients and is considered a clinical sign of the disease. AWP can be present in CF carriers to a lesser extent,^2,4 and has also been associated with focal hyperhidrosis, atopic dermatitis, Raynaud phenomenon, and COX-2 inhibitor use.⁵

While a definitive cause is unknown, it is thought that AWP is caused by dysregulation of sweat glands in the palms through increased expression of aquaporin, a protein crucial in the transport of water between cells.³

AWP is quite rare and benign in nature. However, because of its strong association with CF, genetic screening should be considered in asymptomatic patients. Our patient had been screened in the past and is not a CF carrier. Often, the itching or burning associated with CF is mild and easily controlled. The patient was placed on low dose isotretinoin for treatment of her acne. Interestingly, the patient claimed her eruption no longer appeared after starting isotretinoin therapy. To our knowledge, this is the first reported case of AWP resolving with isotretinoin use.
