Long-term safety and efficacy of dupilumab in adolescents with moderate-to-severe atopic dermatitis
Key clinical point: Dupilumab showed an acceptable safety profile and sustained efficacy through 52 weeks in adolescents with inadequately controlled moderate-to-severe atopic dermatitis (AD).
Major finding: Rate of treatment emergent adverse events was 370.2 events/100 patient-years, with most being mild/moderate. At least 75% improvement in Eczema Area and Severity Index scores was achieved by 81.2% of patients receiving dupilumab at week 52 and 51.9% of patients who were uptitrated from every-4-week (q4w) to every-2-week (q2w) dosing regimen at week 48 after the first uptitration visit.
Study details: Findings are from an ongoing open-label extension study, LIBERTY AD PED-OLE, including 294 adolescents with moderate-to-severe AD who participated in previous dupilumab trials, received dupilumab q4w, and were uptitrated to the weight-tiered q2w dose regimen upon inadequate clinical response.
Disclosures: This study was funded by Sanofi and Regeneron Pharmaceuticals, Inc. Eight authors declared being employees or shareholders of Regeneron Pharmaceuticals or Sanofi, and the other authors reported ties with various sources, including Sanofi and Regeneron.

Postherpetic Pink, Smooth, Annular Convalescing Plaques
The Diagnosis: Granuloma Annulare
A biopsy of a lesion on the right flank demonstrated granulomatous inflammation and interstitial mucin (Figure), characteristic of granuloma annulare (GA).1,2 Granuloma annulare is a relatively common skin disorder with an unknown etiology. It typically presents as smooth, annular, erythematous plaques.1 The most common variants of GA are localized, generalized, and subcutaneous. Our case demonstrated Wolf isotopic response, an unrelated skin disease that forms at the same location as a previously healed skin lesion.2 It is important to be aware of this phenomenon so that it is not confused with a recurrence of herpes zoster virus (HZV).
Although relatively infrequent, GA is the most common isotopic response following HZV infections.3-5 Other postherpetic isotopic eruptions include cutaneous malignancies, lichen planus, sarcoidosis, morphea, reactive perforating collagenosis, psoriasis, and infections, among others.3,5,6 The time between HZV infection and GA can be variable, ranging from a few weeks to many years apart.3
Oftentimes GA will spontaneously resolve within 2 years; however, recurrence is common.7-9 There currently are no standard treatment guidelines. The most promising treatment options include intralesional or topical glucocorticoids for localized GA as well as phototherapy or hydroxychloroquine for widespread disease.8,10
Annular elastolytic giant cell granuloma (also called actinic granuloma) is a rare idiopathic inflammatory skin disease. It is characterized by erythematous annular papules or plaques mainly found on sun-exposed skin, such as the backs of the hands, forearms, or face.11,12 Therefore, based on the distribution of our patient’s lesions, annular elastolytic giant cell granuloma was an unlikely diagnosis. Furthermore, it is not a known postherpetic isotopic reaction. Annular elastolytic giant cell granuloma can appear histologically similar to GA. Differentiating histologic features include a nonpalisading granuloma as well as the absence of mucin and necrobiosis.12
Annular lichen planus is a long-recognized but uncommon clinical variant of lichen planus that typically presents as pruritic, purple, annular plaques on the penis, scrotum, or intertriginous areas.13 The violaceous coloring is more characteristic of lichen planus. Histology is helpful in differentiating from GA.
Nummular eczema presents as scattered, welldefined, pruritic, erythematous, coin-shaped, coin-sized plaques in patients with diffusely dry skin.14 The scaling and serous crusting as well as more prominent pruritus help distinguish it from GA. The appearance of nummular eczema is quite characteristic; therefore, a biopsy typically is unnecessary for diagnosis. However, a potassium hydroxide wet mount examination of a skin scraping should be performed if tinea corporis also is suspected.
Superficial erythema annulare centrifugum classically presents as an annular or arciform pruritic lesion with an advancing outer erythematous edge with an inner rim of scale that most commonly occurs on the lower extremities. 15 The presence of pruritus and trailing scale helps distinguish this lesion from GA. Histologically, there are epidermal changes of hyperplasia, spongiosis, and parakeratosis, as well as lymphohistiocytic infiltrate surrounding the superficial dermal vessels.16
We report this case to highlight GA as the most common postherpetic isotopic response. It should be on the differential diagnosis when a patient presents with erythematous, smooth, annular plaques occurring in the distribution of a resolved case of HZV.

An 82-year-old man presented with painful, pink, smooth, annular convalescing plaques on the right back, flank, and abdomen in a zosteriform distribution involving the T10/11 dermatome. He had a history of hypertension and type 2 diabetes mellitus, and 12 months prior to presentation he had an outbreak of herpes zoster virus in the same distribution that was treated with valacyclovir 1000 mg 3 times daily for 7 days. Over the following month he noticed a resolution of blisters and crusting as they morphed into the current lesions.
New saliva-based COVID-19 test provides rapid results
A rapid, saliva-based test for COVID-19 could enable testing, diagnosis, and prescribing to take place in a single office visit by immediately confirming whether a patient has the infection and needs to be treated, researchers say. The test has sparked commercial interest and earned additional funding from the Canadian government.
The test uses a DNA aptamer – a short, synthetic oligonucleotide that binds to a specific molecular target – that shows high affinity for the SARS-CoV-2 spike protein and its variants. The approach “can be rapidly adapted to different threats,” as well, Leyla Soleymani, PhD, an associate professor of engineering physics at McMaster University, Hamilton, Ontario, Canada, told this news organization. Her team invented the approach.
Adaptable to other pathogens
Current gold-standard COVID-19 tests are based on reverse transcription-polymerase chain reaction (RT-PCR), which are sensitive but costly, complicated, and require waiting at least a couple of days for results, according to Dr. Soleymani and colleagues. Rapid nucleic acid and antigen tests have only “moderate” sensitivity and specificity, particularly when viral loads are low. None have been shown to work well with saliva samples.
By contrast, the new test “uses a reader and test cartridges, similar to the glucose reader,” said Dr. Soleymani, who is also Canada Research chair in Miniaturized Biomedical Devices. A small sample of saliva is added to a chemical reagent and inserted into the reader, which is attached to a smartphone. Once commercialized, the point-of-care test is expected to be performed quickly in a physician’s office or in a clinic.
“The same reader can be applied to a variety of infectious diseases or infection panels by developing new cartridges,” Dr. Soleymani explained. “Noroviruses and bacteria such as C. difficile are on our list” to examine next.What’s more, she added, “this test is ideally positioned for settings where access to centralized labs is not possible, such as less developed countries.”
The team’s recent studies seem to support the promise. A study published last year in the international edition of Angewandte Chemie documents the development of the test, which at that point could detect wild-type SARS-CoV-2 and its Alpha and Delta variants in unprocessed saliva samples in 10 minutes with 80.5% sensitivity and 100% specificity.
This study was followed in January 2022 by a paper in Chemistry showing that the device also detected Alpha, Gamma, Epsilon, Kappa, and Omicron variants, demonstrating its potential for recognizing rapidly evolving targets such as those found in SARS-CoV-2.
In another demonstration of its versatility, the technology was recently adapted and successfully detected animal viruses from saliva samples.
Commercial and government funding
The findings prompted Zentek, an intellectual property development and commercialization company in Guelph, Ont., to license the technology, with plans to invest more than $1 million in the next 5 years to scale up production of the test components and adapt the technology for other forms of infection.
Furthermore, the collaborative efforts required to develop the test and move it forward gained funding from Canada’s Natural Sciences and Engineering Research Council, which is investing nearly $1.5 million in the form of two grants: $1 million to further streamline the technology development in preparation for the next pandemic and $488,440 (including $140,000 from Zentek) to get the current test to market as quickly as possible.
Meanwhile, Dr. Soleymani is urging clinicians “to be open to nontraditional diagnostic approaches even if the traditional tests do the job. Such tests are more rapid and can be used to enable personalized medicine. Our success relies on collaboration and support from clinicians.”
Further validation needed
Daniel Kuritzkes, MD, chief of infectious diseases at Brigham and Women’s Hospital and the Harriet Ryan Albee Professor of Medicine at Harvard Medical School, Boston, commented on the study in response to a request from this news organization.
While “it’s always good to have more testing options available,” he said, “we don’t yet have very much information about performance characteristics of the test – that is, its sensitivity and specificity. I’d like to see the performance characteristics of this test compared to PCR tests and to the current rapid antigen tests using a large number of patient samples with currently circulating variants, and tests over time to see how soon tests become positive after symptom onset and for how long they remain positive.”
“Further validation studies and emergency use authorization or approval by regulatory authorities are needed before we will see this test implemented in the field,” Dr. Kuritzkes concluded.

Daniel Kuritzkes, MD, chief of infectious diseases at Brigham and Women’s Hospital and the Harriet Ryan Albee Professor of Medicine at Harvard Medical School, Boston, commented on the study in response to a request from this news organization.
While “it’s always good to have more testing options available,” he said, “we don’t yet have very much information about performance characteristics of the test – that is, its sensitivity and specificity. I’d like to see the performance characteristics of this test compared to PCR tests and to the current rapid antigen tests using a large number of patient samples with currently circulating variants, and tests over time to see how soon tests become positive after symptom onset and for how long they remain positive.”
“Further validation studies and emergency use authorization or approval by regulatory authorities are needed before we will see this test implemented in the field,” Dr. Kuritzkes concluded.

A rapid, saliva-based test for COVID-19 could enable testing, diagnosis, and prescribing to take place in a single office visit by immediately confirming whether a patient has the infection and needs to be treated, researchers say. The test has sparked commercial interest and earned additional funding from the Canadian government.
The test uses a DNA aptamer – a short, synthetic oligonucleotide that binds to a specific molecular target – that shows high affinity for the SARS-CoV-2 spike protein and its variants. The approach “can be rapidly adapted to different threats,” as well, Leyla Soleymani, PhD, an associate professor of engineering physics at McMaster University, Hamilton, Ontario, Canada, told this news organization. Her team invented the approach.
Adaptable to other pathogens
Current gold-standard COVID-19 tests are based on reverse transcription-polymerase chain reaction (RT-PCR), which are sensitive but costly, complicated, and require waiting at least a couple of days for results, according to Dr. Soleymani and colleagues. Rapid nucleic acid and antigen tests have only “moderate” sensitivity and specificity, particularly when viral loads are low. None have been shown to work well with saliva samples.
By contrast, the new test “uses a reader and test cartridges, similar to the glucose reader,” said Dr. Soleymani, who is also Canada Research chair in Miniaturized Biomedical Devices. A small sample of saliva is added to a chemical reagent and inserted into the reader, which is attached to a smartphone. Once commercialized, the point-of-care test is expected to be performed quickly in a physician’s office or in a clinic.
“The same reader can be applied to a variety of infectious diseases or infection panels by developing new cartridges,” Dr. Soleymani explained. “Noroviruses and bacteria such as C. difficile are on our list” to examine next.What’s more, she added, “this test is ideally positioned for settings where access to centralized labs is not possible, such as less developed countries.”
The team’s recent studies seem to support the promise. A study published last year in the international edition of Angewandte Chemie documents the development of the test, which at that point could detect wild-type SARS-CoV-2 and its Alpha and Delta variants in unprocessed saliva samples in 10 minutes with 80.5% sensitivity and 100% specificity.
This study was followed in January 2022 by a paper in Chemistry showing that the device also detected Alpha, Gamma, Epsilon, Kappa, and Omicron variants, demonstrating its potential for recognizing rapidly evolving targets such as those found in SARS-CoV-2.
In another demonstration of its versatility, the technology was recently adapted and successfully detected animal viruses from saliva samples.
Commercial and government funding
The findings prompted Zentek, an intellectual property development and commercialization company in Guelph, Ont., to license the technology, with plans to invest more than $1 million in the next 5 years to scale up production of the test components and adapt the technology for other forms of infection.
Furthermore, the collaborative efforts required to develop the test and move it forward gained funding from Canada’s Natural Sciences and Engineering Research Council, which is investing nearly $1.5 million in the form of two grants: $1 million to further streamline the technology development in preparation for the next pandemic and $488,440 (including $140,000 from Zentek) to get the current test to market as quickly as possible.
Meanwhile, Dr. Soleymani is urging clinicians “to be open to nontraditional diagnostic approaches even if the traditional tests do the job. Such tests are more rapid and can be used to enable personalized medicine. Our success relies on collaboration and support from clinicians.”

HPV vaccination with Cervarix ‘unmasks’ cervical lesions from non-vax strains
Vaccines against human papillomavirus have been hailed as a success: they have been shown to decrease the incidence of cervical lesions associated with the HPV types that are in the vaccine.
However,
An expert not involved in the research said the new data “tell us to be a little bit careful.” Although the HPV types not included in the vaccine are rarer and less aggressive, they can still cause cancer.
The data come from the Costa Rica HPV Vaccine Trial, which involved more than 10,000 women aged 18-25 years. The HPV vaccine used in the trial was Cervarix, from GlaxoSmithKline. It covers the two leading causes of cervical cancer, HPV-16 and -18, and provides partial protection against three other genotypes.
After a follow-up of 11 years, among vaccinated women, there was an excess of precancerous cervical lesions caused by genotypes not included in the vaccine, resulting in negative vaccine efficacy for those HPV variants.
The increase wasn’t enough to offset the overall benefit of vaccination when all genotypes were considered, said the researchers, led by Jaimie Shing, PhD, a postdoctoral research fellow at the National Cancer Institute in Bethesda, Md.
Vaccinated women “still had long-term absolute reductions in high-grade lesions,” they pointed out.
The net protection “remained considerable, emphasizing the importance of HPV vaccination for cervical cancer prevention,” the team concluded.
The findings were published online in The Lancet Oncology.
The results are likely the first evidence to date of “clinical unmasking” with HPV vaccination, meaning that protection against the strains covered by the vaccine leaves women more prone to attack from other carcinogenic HPV variants.
This phenomenon “could attenuate long-term reductions in high-grade disease following successful implementation of HPV vaccination programs,” the investigators commented.
Highlighting a need for caution
The take-home message from the trial is that “we have to be careful,” said Marc Steben, MD, co-President of HPV Global Action and a professor at the University of Montreal.
He noted that the Cervarix HPV vaccine used in the trial is not the vaccine that is used now in developed nations.
The current standard HPV vaccine is Gardasil 9 (Merck), which offers broader coverage against nine HPV types (types 6, 11, 16, 18, 31, 33, 45, 52, and 58).
There are 12 main carcinogenic HPV genotypes, so unmasking of other strains is still possible with Gardasil 9, he said.
There is another issue, Dr. Steben added. The success of HPV vaccinations - a nearly 90% reduction in invasive cervical cancer in women who are vaccinated at a young age – has led to questions about the future role of routine cervical cancer screening.
“Some people are saying that if we achieve 90% coverage, we might” eliminate community transmission and no longer need to screen, he said.
These trial results “tell us to be a little bit careful,” Dr. Steben continued. Those HPV types that are less aggressive and rarer than HPV-16 and -18 “can still cause cancer and might be there and surprise us. It could take more time than we thought” to get to the point where screening can be eliminated.
“There might be a little problem if we stop too early,” he said.
Study details
During the period 2004-2005, the investigators randomly assigned 3,727 women aged 18-25 years to receive Cervarix and 3,739 to a control group that received the hepatitis A vaccine; after 4 years, the control group also received Cervarix and exited the study. They were replaced by an unvaccinated control group of 2,836 women. The new control group and the original HPV vaccine group were followed for an additional 7 years.
In years 7-11 of the trial, the investigators found 9.2 additional cervical intraepithelial neoplasias of grade 2 or worse (CIN2+) from HPV types not covered by Cervarix per 1,000 vaccinated women in comparison with unvaccinated participants. This corresponds to –71.2% negative vaccine efficacy against CIN2+ lesions of HPV types not covered by the vaccine.
There were 8.3 additional CIN3+ lesions from nontargeted HPV strains per 1,000 vaccinated women in comparison with unvaccinated participants, which corresponds to –135% negative vaccine efficacy.
Overall, however, there was a net benefit of vaccination, with 27 fewer CIN2+ lesions when all HPV genotypes – vaccine covered or not – were considered per 1,000 vaccinated women over the entire 11 years of follow-up.
There were also 8.7 fewer CIN3+ lesions across all genotypes per 1,000 vaccinated women, but the benefit was not statistically significant.
Among the study limits, the team was unable to evaluate the effect of clinical unmasking on cervical cancer, because women were treated for high-grade cervical lesions before cases could progress to cervical cancer.
The trial was funded by the National Cancer Institute and the National Institutes of Health Office of Research on Women’s Health. GlaxoSmithKline provided the Cervarix vaccine and supported aspects of the trial. Two authors are named inventors on U.S. government–owned HPV vaccine patents with expired licenses to GlaxoSmithKline and Merck. Dr. Steben is an adviser/speaker for many companies, including GlaxoSmithKline and Merck.

Pandemic public health measures may have mitigated Kawasaki disease
The social behavior associated with the COVID-19 pandemic may have reduced the incidence of Kawasaki disease, according to results of a cohort study of nearly 4,000 children.
The incidence of Kawasaki disease in the United States declined by 28.2% between 2018 and 2020, possibly as a result of factors including school closures, mask mandates, and reduced ambient pollution that might reduce exposure to Kawasaki disease (KD) in the environment, but a potential association has not been explored, wrote Jennifer A. Burney, PhD, of the University of California, San Diego, and colleagues.
KD received greater attention in the public and medical communities because of the emergence of multisystem inflammatory syndrome in children (MIS-C), which is similar to, but distinct from, KD, and because of the noticeable drop in KD cases during the pandemic, the researchers said.
In a multicenter cohort study published in JAMA Network Open , the researchers reviewed data from 2,461 consecutive patients with KD who were diagnosed between Jan. 1, 2018, and Dec. 31, 2020. They conducted a detailed analysis of analysis of 1,461 children with KD who were diagnosed between Jan. 1, 2002, and Nov. 15, 2021, at Rady Children’s Hospital San Diego (RCHSD), using data from before, during, and after the height of the pandemic. The median age of the children in the RCHSD analysis was 2.8 years, 62% were male, and 35% were Hispanic.
Overall, the prevalence of KD declined from 894 in 2018 to 646 in 2020, across the United States, but the decline was uneven, the researchers noted.
In the RCHSD cohort in San Diego, KD cases in children aged 1-5 years decreased significantly from 2020 to 2021 compared to the mean number of cases in previous years (22 vs. 44.9, P = .02). KD cases also decreased significantly among males and Asian children.
Notably, the occurrence of the KD clinical features of strawberry tongue, enlarged cervical lymph node, and subacute periungual desquamation decreased during 2020 compared with the baseline period, although only strawberry tongue reached statistical significance (39% vs. 63%, P = .04). The prevalence of patients with an enlarged lymph node was 21% in 2020 vs. 32% prior to the pandemic (P = .09); the prevalence of periungual desquamation during these periods was 47% vs. 58%, P = .16).
The researchers also used data from Census Block Groups (CBGs) to assess the impact of mobility metrics and environmental exposures on KD during the pandemic for the San Diego patient cohort. They found that KD cases during the pandemic were more likely to occur in neighborhoods of higher socioeconomic status, and that neighborhoods with lower levels of nitrous oxides had fewer KD cases.
Overall, “The reduction in KD case numbers coincided with masking, school closures, reduced circulation of respiratory viruses, and reduced air pollution,” the researchers wrote in their discussion of the findings. “A rebound in KD case numbers to prepandemic levels coincided with the lifting of mask mandates and, subsequently, the return to in-person schooling,” they wrote.
The study findings were limited by several factors including the small sample sizes, which also limit the interpretation of mobility and pollution data, the researchers noted. Other limitations include the high interannual variability of KD and the inclusion of 2021 rebound data from the San Diego region only.
“Although our original hypothesis was that shelter-in-place measures would track with reduced KD cases, this was not borne out by the San Diego region data. Instead, the San Diego case occurrence data suggest that exposures that triggered KD were more likely to occur in the home, with a shift toward households with higher SES during the pandemic,” the researchers noted. However, “The results presented here are consistent with a respiratory portal of entry for the trigger(s) of KD,” they said.
Study fails to validate its conclusions
“This study attempts to test the hypothesis that various social restrictions were associated with a decrease in rate of diagnosed Kawasaki disease cases during portions of the SARS-CoV-2 pandemic,” Mark Gorelik, MD, assistant professor of pediatrics at Columbia University, New York, said in an interview.
“However, it appears that it fails to achieve this conclusion and I disagree with the findings,” said Dr. Gorelik, who was not involved in the study but served as first author on an updated Kawasaki disease treatment guideline published earlier this spring in Arthritis & Rheumatology.
“The study does not find statistically significant associations either with shelter in place orders or with cell phone mobility data, as stated in the conclusion, directly contradicting its own claim,” Dr. Gorelik said. “Secondly, the study makes an assumption that various methods, especially the wearing of masks by children and school closures, had a significant effect on the spread of respiratory viruses. There are no prospective, population based, controlled real world studies that validate this claim, and two prospective controlled real-world studies that dispute this,” he emphasized. “Cloth masks and surgical masks, which were the types of masks worn by school students, are also known to have a nonsignificant and paltry – in the latter, certainly less than 50%, and perhaps as little as 10% – effect on the reduction of respiratory viral spread,” he added.
“Mechanistic studies on mask wearing may suggest some mask efficacy, but these studies are as valid as mechanistic studies showing the effect of various antifungal pharmaceuticals on the replication of SARS-CoV-2 virus in culture, meaning only valid as hypothesis generating, and ultimately the latter hypothesis failed to bear out,” Dr. Gorelik explained. “We do not know the reason why other respiratory viruses and non-SARS-CoV-2 coronaviruses declined during the pandemic, but we do know that despite this, the SARS-CoV-2 coronavirus itself did not appear to suffer the same fate. Thus, it is very possible that another factor was at work, and we know that during other viral pandemics, typically circulating viruses decline, potentially due to induction of interferon responses in hosts, in a general effect known as ‘viral interference,’ ” he said.
“Overall, we must have robust evidence to support benefits of hypotheses that have demonstrated clear damage to children during this pandemic (such as school closures), and this study fails to live up to that requirement,” Dr. Gorelik said.
The study was supported by the Gordon and Marilyn Macklin Foundation and the Patient-Centered Outcomes Research Institute. Dr. Burney and Dr. Gorelik had no financial conflicts to disclose.

KD received greater attention in the public and medical communities because of the emergence of multisystem inflammatory syndrome in children (MIS-C), which is similar to, but distinct from, KD, and because of the noticeable drop in KD cases during the pandemic, the researchers said.
In a multicenter cohort study published in JAMA Network Open , the researchers reviewed data from 2,461 consecutive patients with KD who were diagnosed between Jan. 1, 2018, and Dec. 31, 2020. They conducted a detailed analysis of analysis of 1,461 children with KD who were diagnosed between Jan. 1, 2002, and Nov. 15, 2021, at Rady Children’s Hospital San Diego (RCHSD), using data from before, during, and after the height of the pandemic. The median age of the children in the RCHSD analysis was 2.8 years, 62% were male, and 35% were Hispanic.
Overall, the prevalence of KD declined from 894 in 2018 to 646 in 2020, across the United States, but the decline was uneven, the researchers noted.
In the RCHSD cohort in San Diego, KD cases in children aged 1-5 years decreased significantly from 2020 to 2021 compared to the mean number of cases in previous years (22 vs. 44.9, P = .02). KD cases also decreased significantly among males and Asian children.
Notably, the occurrence of the KD clinical features of strawberry tongue, enlarged cervical lymph node, and subacute periungual desquamation decreased during 2020 compared with the baseline period, although only strawberry tongue reached statistical significance (39% vs. 63%, P = .04). The prevalence of patients with an enlarged lymph node was 21% in 2020 vs. 32% prior to the pandemic (P = .09); the prevalence of periungual desquamation during these periods was 47% vs. 58%, P = .16).
The researchers also used data from Census Block Groups (CBGs) to assess the impact of mobility metrics and environmental exposures on KD during the pandemic for the San Diego patient cohort. They found that KD cases during the pandemic were more likely to occur in neighborhoods of higher socioeconomic status, and that neighborhoods with lower levels of nitrous oxides had fewer KD cases.
Overall, “The reduction in KD case numbers coincided with masking, school closures, reduced circulation of respiratory viruses, and reduced air pollution,” the researchers wrote in their discussion of the findings. “A rebound in KD case numbers to prepandemic levels coincided with the lifting of mask mandates and, subsequently, the return to in-person schooling,” they wrote.
The study findings were limited by several factors including the small sample sizes, which also limit the interpretation of mobility and pollution data, the researchers noted. Other limitations include the high interannual variability of KD and the inclusion of 2021 rebound data from the San Diego region only.
“Although our original hypothesis was that shelter-in-place measures would track with reduced KD cases, this was not borne out by the San Diego region data. Instead, the San Diego case occurrence data suggest that exposures that triggered KD were more likely to occur in the home, with a shift toward households with higher SES during the pandemic,” the researchers noted. However, “The results presented here are consistent with a respiratory portal of entry for the trigger(s) of KD,” they said.
Study fails to validate its conclusions
“This study attempts to test the hypothesis that various social restrictions were associated with a decrease in rate of diagnosed Kawasaki disease cases during portions of the SARS-CoV-2 pandemic,” Mark Gorelik, MD, assistant professor of pediatrics at Columbia University, New York, said in an interview.
“However, it appears that it fails to achieve this conclusion and I disagree with the findings,” said Dr. Gorelik, who was not involved in the study but served as first author on an updated Kawasaki disease treatment guideline published earlier this spring in Arthritis & Rheumatology.
“The study does not find statistically significant associations either with shelter in place orders or with cell phone mobility data, as stated in the conclusion, directly contradicting its own claim,” Dr. Gorelik said. “Secondly, the study makes an assumption that various methods, especially the wearing of masks by children and school closures, had a significant effect on the spread of respiratory viruses. There are no prospective, population based, controlled real world studies that validate this claim, and two prospective controlled real-world studies that dispute this,” he emphasized. “Cloth masks and surgical masks, which were the types of masks worn by school students, are also known to have a nonsignificant and paltry – in the latter, certainly less than 50%, and perhaps as little as 10% – effect on the reduction of respiratory viral spread,” he added.
“Mechanistic studies on mask wearing may suggest some mask efficacy, but these studies are as valid as mechanistic studies showing the effect of various antifungal pharmaceuticals on the replication of SARS-CoV-2 virus in culture, meaning only valid as hypothesis generating, and ultimately the latter hypothesis failed to bear out,” Dr. Gorelik explained. “We do not know the reason why other respiratory viruses and non-SARS-CoV-2 coronaviruses declined during the pandemic, but we do know that despite this, the SARS-CoV-2 coronavirus itself did not appear to suffer the same fate. Thus, it is very possible that another factor was at work, and we know that during other viral pandemics, typically circulating viruses decline, potentially due to induction of interferon responses in hosts, in a general effect known as ‘viral interference,’ ” he said.
“Overall, we must have robust evidence to support benefits of hypotheses that have demonstrated clear damage to children during this pandemic (such as school closures), and this study fails to live up to that requirement,” Dr. Gorelik said.
The study was supported by the Gordon and Marilyn Macklin Foundation and the Patient-Centered Outcomes Research Institute. Dr. Burney and Dr. Gorelik had no financial conflicts to disclose.

Understanding filler reversal with hyaluronidase
Hyaluronic acid is the most common filler used in the United States for cosmetic procedures.
. However, there has been little research and there are no formal clinical guidelines on its use. Hyaluronidase is approved by the Food and Drug Administration for several indications, but its use in cosmetic procedures is off-label.Hyaluronic acid filler complications can be local and transient or delayed and/or dangerous. Local reactions generally improve over time or respond to symptomatic care. But granulomatous reactions, misplaced injection, adverse aesthetic outcomes, and vascular occlusion are some of the detrimental outcomes that require immediate treatment, often using hyaluronidase, a naturally occurring enzyme that degrades hyaluronic acid.
Hyaluronic acid products vary in concentration, cross-linking, type of cross-linker used, and particle size, and therefore display different degradation patterns with hyaluronidase. The three hyaluronidase products available also vary in concentration, source, and enzyme activity. Hyaluronidase has a half-life of 2 minutes but has a duration of action of 24-48 hours depending on the product used.
In an interesting study by Casabona G et al., the dose and activity of five hyaluronidase products available worldwide were used to degrade five different fillers (Juvederm Volbella, Voluma, and Ultraplus; Belotero, and Belotero Balance) with various concentrations and cross-linking in human skin. The results showed that the Vycross products (Juvederm Voluma) are the least sensitive to hyaluronidase and require the greatest concentration of hyaluronidase and a longer time for dissolution requiring up to three times more hyaluronidase to degrade the same volume of other hyaluronic acid products.
In addition, the ovine hyaluronidase product marketed in the United States as Vitrase had the greatest activity against the range of hyaluronic acids used in the trial. Higher concentrations of hyaluronidase also could produce type-I hypersensitivity reactions and angioedema in susceptible patients as evidenced by eosinophilic tissue reactions at concentrations greater than 300 IU.
Hyaluronidase is stored at cool temperatures (35-46° F). It can be reconstituted with saline, water, or bacteriostatic saline for reducing injection site pain; however, it should not be mixed with local anesthetic. The volume of diluent used depends on the surface area treated and ranges from 1 mL to 10 mL. Smaller volumes are used for more concentrated local injection and larger volumes for more precise dosing.
For impending necrosis, hyaluronidase should be used within minutes to hours of blanching of the skin and the area should be flooded every 30 minutes until the tissue has reperfused. Depending on the type of filler used, the volume of injection varies and the area should continually be injected and tissue response observed. A high-dosed large-volume protocol allows the tissue perfusion to gradually infiltrate the vessel walls. Recommendations are 2 mL of bacteriostatic saline diluted with a vial of hyaluronidase. Retrobulbar injection of hyaluronidase within minutes of retinal artery occlusion in doses of 150-200 units in 2-4 mL of diluent into the inferolateral orbit by an experienced ophthalmologist or oculoplastic surgeon is recommended.
Although there is no consensus, there are various clinical studies using hyaluronidase dilutions varying between 5 and 30 units to break down 0.1mg/mL of hyaluronic acid for the reversal of facial hyaluronic acid fillers. In my clinical experience, the recommendation is that, apart from necrosis, the concentration used is titrated to clinical efficacy, which can also be done over multiple appointments every 48 hours until the desired outcome is achieved.
Complications from hyaluronidase injection include local tissue erythema, edema, pain, allergic reactions, and anaphylaxis. An intradermal patch test of 10-20 units of hyaluronidase in the forearm can be done in patients with a history of allergy to hyaluronidase, which, in people with sensitivity, results in a wheal within 30 minutes of injection. If a patient has a positive patch test, hyaluronidase cannot be used. In addition, a history of allergic reactions to bees may pose a heightened reaction to hyaluronidase and is a contraindication to use.
It is recommended that any practitioner using hyaluronic acid fillers keep 2-3 vials of hyaluronidase available at all times in the event of a vascular emergency. Stability, storage, and expiration dates should also be monitored closely.

“How long, how long to sing this song?”
“My soul is in deep anguish. How long, Lord, how long?” – Psalm 6
. A once-common word in the 1800s, it fell steeply in popularity in the 20th century. Lately, I see it everywhere. It’s a beautiful word, capturing not only sorrow, but also weariness. It is also audacious, facing injustice and acknowledging that it ought not be this way, and communal, bearing witness to the shared hardship of being human. The Hebrew scriptures captured the experience of lament in the form of psalms, from the Greek, psalmoi or “words to accompany the music.” A few thousand years later, the words still resonate, especially in times of grief. “I am weary with my groaning; all the night make I my bed to swim; I water my couch with my tears.”
“Hair loss” is not the chief complaint you want to see when running behind in clinic – it’s never a 15-minute visit. A woman in her late 30s with wavy, light-brown hair that grew to her waistline was seated on the exam chair. When I sat across from her, I couldn’t see her scalp. No erythema or scale. No frontal band of hair loss. Just a bit thin everywhere. Perhaps another post-COVID telogen? This might be easy. I blew right by her mother, who was sitting in the corner of the room. Her black and white horizontal striped shirt seemed to match her gray and white hair. She looked worried.
Having perused my patient’s labs and done an exam, I announced that the diagnosis was telogen effluvium. “There are many possible causes, stress is a common one. Have you been under a lot of stress lately?” (The answer is always yes, thus providing a good foothold to climb out of a hair-loss visit). “Yes. My 1-year-old daughter died last year. She had choked on a cashew from a granola bar given by her sister.” I gasped and turned from her green eyes to her mom’s. Without saying a word, mom pleaded with me to help. “I don’t know what to say,” I said, “I’m so sorry.” Neither replied.
On the commute home that day I listened to a live recording of the U2 song, “40.” I had recently read about it in a touching essay about lament by Enuma Okoro of the Financial Times. I thought about my patient’s suffering and the brutal injustice of fate. It feels like it’s everywhere lately. Reporting from the events in Ukraine, Buffalo, Uvalde, Tulsa has put agonized faces like hers in the public square for us all to gape at and quietly mourn.
Even from a secular lens, it can be seen that a beauty of psalms is how they move from despair to hope. Prayers will be answered. Things will get better. Turn up the volume and feel the urgency and pathos Bono injects into your soul as he sings the refrain; “How long, how long? How long to sing this song?” In the live version we the audience take over for him. The words accompanying the music swell over the crowd. How much longer? How much more suffering? My patient’s hair will grow back. It will take years. All we can do is lament with her.

Employment and buyout agreements
. The most common question was, “Do I really need to go to the trouble and expense of negotiating them?” If you have more than one physician in your group, you absolutely do need written contracts for a variety of reasons, but mostly to avoid conflicts later on. The proverbial “handshake agreement” is worthless in a major business dispute; everyone loses in such situations except the lawyers and accountants.
Mergers and buy-ins were covered at some length in my two previous columns. If the arrangement is to be one of employer and employees rather than a merger of equal partners, you will need an employment agreement to cover duties, requirements, expectations, and benefits. They define how each practitioner/employee will be paid, along with paid time off, health insurance, expense allowances, and malpractice coverage, among other basics. The more that is spelled out in the employment agreement, the fewer disagreements you are likely to have down the road.
Many employment contracts include a “termination without cause” clause, which benefits both the practice and the practitioners. It allows a practice to terminate a new associate if it feels a mistake has been made, even if he or she has done nothing wrong. On the other hand, the newcomer has the option to terminate if a better offer arises, their spouse hates the area, or for any other reason.
Buyouts should be addressed in advance as well. Several recent correspondents told me they didn’t see the necessity of writing a buyout agreement, because they plan to eventually sell their practice, rendering any buyout conditions moot. But what happens if an associate dies, becomes permanently disabled, or abruptly decides to leave the practice? If you haven’t prepared for such eventualities, you could find yourself receiving a demand from your ex-partner (or surviving spouse) for immediate payment of that partner’s portion of the practice’s value. And your valuation of the practice is likely to be severely at odds with the other party’s. Meanwhile, remaining partners must cover all the practice’s expenses and deal with an increased patient load.
A buyout agreement avoids these problems by planning for such eventualities in advance. You must agree on how a buyout amount will be valued. As I’ve said in previous columns, I strongly advise using a formula, not a fixed amount. If a buyout is based on 15- or 20-year-old reimbursements, the buyout will have no relationship to what the partners are currently being paid. Likewise, any buyout calculated at “appraised value” is a problem, because the buyout amount remains a mystery until an appraisal is performed. If the appraised value ends up being too high, the remaining owners may refuse to pay it. Have an actuary create a formula, so that a buyout figure can be calculated at any time. This area, especially, is where you need experienced, competent legal advice.
To avoid surprises, any buyout should require ample notice (6-12 months is common) to allow time to rearrange finances and recruit a new provider. Vesting schedules, similar to those used in retirement plans, are also popular. If a partner leaves before a prescribed time period has elapsed – say, 20 years – the buyout is proportionally reduced.
Buyouts can also be useful when dealing with noncompete agreements, which are notoriously difficult (and expensive) to enforce. One solution is a buyout penalty; a departing partner can compete with his or her former practice, but at the cost of a substantially reduced buyout. This permits competition, but discourages it, and compensates the targeted practice.
Buyouts are also a potential solution to some buy-in issues. A new associate entering an established practice may not be able to contribute assets equal to existing partners’ stakes and may lack the cash necessary to make up the difference. One alternative is to agree that any inequalities will be compensated at the other end in buyout value. Those partners contributing more assets will receive larger buyouts than those contributing less.
As I’ve said many times, these are not negotiations to undertake on your own. Enlist the aid of a consultant or attorney (or both) with ample medical practice experience.

. The most common question was, “Do I really need to go to the trouble and expense of negotiating them?” If you have more than one physician in your group, you absolutely do need written contracts for a variety of reasons, but mostly to avoid conflicts later on. The proverbial “handshake agreement” is worthless in a major business dispute; everyone loses in such situations except the lawyers and accountants.
Mergers and buy-ins were covered at some length in my two previous columns. If the arrangement is to be one of employer and employees rather than a merger of equal partners, you will need an employment agreement to cover duties, requirements, expectations, and benefits. They define how each practitioner/employee will be paid, along with paid time off, health insurance, expense allowances, and malpractice coverage, among other basics. The more that is spelled out in the employment agreement, the fewer disagreements you are likely to have down the road.
Many employment contracts include a “termination without cause” clause, which benefits both the practice and the practitioners. It allows a practice to terminate a new associate if it feels a mistake has been made, even if he or she has done nothing wrong. On the other hand, the newcomer has the option to terminate if a better offer arises, their spouse hates the area, or for any other reason.
Buyouts should be addressed in advance as well. Several recent correspondents told me they didn’t see the necessity of writing a buyout agreement, because they plan to eventually sell their practice, rendering any buyout conditions moot. But what happens if an associate dies, becomes permanently disabled, or abruptly decides to leave the practice? If you haven’t prepared for such eventualities, you could find yourself receiving a demand from your ex-partner (or surviving spouse) for immediate payment of that partner’s portion of the practice’s value. And your valuation of the practice is likely to be severely at odds with the other party’s. Meanwhile, remaining partners must cover all the practice’s expenses and deal with an increased patient load.
A buyout agreement avoids these problems by planning for such eventualities in advance. You must agree on how a buyout amount will be valued. As I’ve said in previous columns, I strongly advise using a formula, not a fixed amount. If a buyout is based on 15- or 20-year-old reimbursements, the buyout will have no relationship to what the partners are currently being paid. Likewise, any buyout calculated at “appraised value” is a problem, because the buyout amount remains a mystery until an appraisal is performed. If the appraised value ends up being too high, the remaining owners may refuse to pay it. Have an actuary create a formula, so that a buyout figure can be calculated at any time. This area, especially, is where you need experienced, competent legal advice.

Ready to make a difference, dermatologist takes the helm as AMA president
Jack S. Resneck Jr., MD, is not usually the loudest voice in the room, but when he speaks, his words carry a heft and an appeal that is straightforward and undeniable.
That was on full display as
He did not mince words when it came to describing the current landscape. “I doubt you imagined a divided country such as this, where physicians and public health officials often face antiscience aggression and threats of violence simply for doing our jobs,” he said. “You probably didn’t plan on insurers questioning every prescription and every procedure you asked for. Or government criminalizing routine and vital health care, enshrining discrimination against our LGBTQ patients or attacking a woman’s right to control health care decisions that should only be between her and her doctor,” said Dr. Resneck.
But, he added, all was not lost. “While it would be easy to get overwhelmed by despair as I begin this new role, I’ve never been prouder of my physician colleagues,” he said.
Dr. Resneck is the first dermatologist to lead the 175-year-old organization since 1925. Colleagues in the field speak of pride in having one of their own at the top, and they are even more complimentary about his depth of health policy knowledge, his communications skills, and his ability to find common ground.
“He loves looking at both sides,” said Marta J. Van Beek, MD, clinical professor of dermatology at the University of Iowa, Iowa City. “That’s how he builds consensus,” said Dr. Van Beek, who has known Dr. Resneck for more than 20 years, since they were chief dermatology residents – she at Iowa and he at UCSF.
Dr. Van Beek and Dr. Resneck have a deep interest in health policy and have long worked side by side on committees at both the American Academy of Dermatology (AAD) and the AMA. She looks back to the lead-up period before the 2010 passage of the Affordable Care Act as one of Dr. Resneck’s shining moments. “Those were contentious times in medicine,” Dr. Van Beek told this news organization. Dr. Resneck, as chair of the AAD’s Council on Government Affairs and Health Policy from 2008 to 2012, rallied the board to agree on a set of health care reform principles, she noted.
Dr. Resneck is “really very unifying,” agreed Bruce A. Brod, MD, clinical professor of dermatology at the University of Pennsylvania, Philadelphia. Dr. Brod has worked with Dr. Resneck for 2 decades on various committees at the AAD. They’ve also known each other through the AMA House of Delegates.
Now Dr. Brod is following in Dr. Resneck’s footsteps as chair of the AAD’s Council on Government Affairs and Health Policy. “Big shoes to fill there,” said Dr. Brod. He said he’s been inspired by Dr. Resneck’s always-positive approach, punctuated by his ever-constant belief that “there’s a lot more common ground than meets the eye here.”
“I really think he’s the perfect leader at this time,” he said.
Outgoing AMA President Gerald E. Harmon, MD, said that Dr. Resneck’s long experience as a teacher and a mentor, and what he describes as a “good, active listening talent,” have been integral to his success as a leader. He expects those qualities to make Dr. Resneck an effective advocate for all of medicine. “He identifies the problem, he identifies the gap, and then he establishes a workable, executable plan to close that gap,” Dr. Harmon told this news organization, adding that he’s seen this at work in AMA board meetings.
“He was a good teacher for me,” said Dr. Harmon, who had known Dr. Resneck through the House of Delegates and various AMA councils for at least a decade before they both joined the AMA board. “He can be such a mentor to all age groups, including senior physicians like myself,” said Dr. Harmon.
Dr. Resneck is excited, but also measured. “This has been a tumultuous couple of years in the country with the pandemic and with the fractured politics,” he said in an interview. Thinking about taking on the AMA presidency, he said, “I’ve had some moments of trepidation. I wanted to be sure that I was going to be able to make a difference.”
Long interest in health policy
Growing up in Shreveport, La., as the son of a dermatologist, Dr. Resneck said, “at first, I swore I was going to do something other than medicine.” It was not out of rebellion. He got along fine with his father. He wanted to pursue his own journey.
Dr. Resneck began his long love affair with health policy at Brown University, graduating magna cum laude with honors in public policy. A 1991 U.S. Department of Health & Human Services internship between his junior and senior years helped inform his honors thesis on health care financing policy.
Ultimately, Dr. Resneck did not stray far from his father’s career path. While still at Brown, he decided to go to medical school, entering UCSF in the fall of 1993. “At the end of the day, there was this undeniable influence that he loved his job,” Dr. Resneck said in the interview. His father was energized by the work and helping patients. “If burnout was in his vocabulary, I never heard it,” said Dr. Resneck.
Initially, he did a 1-year internal medicine residency at UCSF, but then switched to dermatology and became chief resident in 2000.
He was quickly pegged as a leader and an inspirational speaker. The AAD gave him its Young Physician Leadership Development Award in 2001, and the AMA gave Dr. Resneck its Excellence in Medicine National Award for Young Physician Leadership in 2004. He began giving talks at national meetings in 2002 and has been busy ever since, addressing the AMA, the AAD, state medical and dermatology societies, subspecialty groups such as the American College of Mohs Surgery and the Association of Professors of Dermatology, and other organizations such as the American Telemedicine Association.
He’s a sought-after speaker in part because of his ability to simply communicate health policy, said Dr. Brod. “He can connect the real-world issues really well to the policy needs and communicate it very well, and come in at just the right level,” he said.
Dr. Resneck has been immersed in policy and practice issues since the start of his career, serving on AAD and AMA committees addressing quality measures, data collection, access to care, workforce issues, and telemedicine. He started writing about dermatology workforce challenges in 2001 and has revisited that topic with regularity.
He has published often on the difficulties of patient access, looking at wait times for appointments, among other issues. In 2018, he expressed concern in a commentary in JAMA Dermatology that private equity purchases of dermatology practices might lead to an improper focus on profits over patients and that it could reduce the diversity of practice models.
At heart, Dr. Resneck is an institutionalist, someone who believes that the “collaborative, collective voice can make change,” said Dr. Brod. Dr. Resneck said as much in his inaugural speech. “I believe those who show up can use levers of power to confront our system’s flaws,” he said. “This is the nerdy policy part of my life, which my friends will force me to admit is most of my life,” said Dr. Resneck.
Prior authorization, telemedicine, equity
Beneath the reserved exterior lies an intense yearning to act on his passions, both at work and at play.
Dr. Resneck notes almost in passing that he likes to ski when he’s not practicing medicine or serving on a committee. Dr. Van Beek – whose family has vacationed with Dr. Resneck, his wife, Ellen Hufbauer, MD, a family medicine physician in Concord, Calif., and their two teenaged children Zachary and Amelia – said he’s “a very good skier.”
She noted that he and his children share the same enthusiasm for researching every aspect of wherever they travel, including the best places to eat. “He embraces work and life with an incredible amount of intellectual curiosity,” Dr. Van Beek said.
That curiosity – and the passion to make a difference – has driven his deep dives into what he sees as the corrosive practice of prior authorization and the promise of telemedicine, which he has explained and supported in testimony on Capitol Hill.
Dr. Brod said that Dr. Resneck was among those who helped convince the federal government to expand coverage for telemedicine during the COVID-19 pandemic. “He brought together his patient experience in dermatology and his policy experience,” and was able to deftly explain how it could increase access during the shutdown, said Dr. Brod.
Prior authorization gets him fired up. “We’ve reached a point where there’s almost not anything I will write a prescription for that doesn’t oftentimes require all of these hoops that we have to jump through,” he told this news organization. Prescriptions for generic topical cortisones that have been around for 50 years “now all of the sudden require a week of arguing,” said Dr. Resneck. In the meantime, patients aren’t getting treatment, he said.
Dr. Resneck’s passion for health equity is borne in part out of the racism witnessed by him and his family, including an uncle who started an antisegregationist newspaper and was kicked out of medical school for his views in the 1950s. Dr. Resneck said he had a rudimentary understanding of racism as a youngster. But he told the AMA delegates, “I knew enough at age 16 to write an op-ed in our city’s newspaper about the need to remove Confederate monuments from our courthouse lawn.” Added Dr. Resneck, “You can imagine how that went over in 1987.”
The pandemic shined a bright light on inequities and heightened awareness of “the institutionalized systems that have perpetuated racism and gender discrimination in medicine for as far back as we want to look,” Dr. Resneck said during his inaugural speech. Pointedly, he told his colleagues that “the AMA has not always been on the right side of history,” adding, “Each of us must do our part to eliminate health inequities by engaging in antiracist and antisexist work.”
That kind of talk is signature Resneck, said Dr. Brod. “He’s not afraid to exhibit very brave leadership,” especially “when there are issues that jeopardize the needs of patient access or patient safety,” he said.
“He’ll be a tremendous AMA president,” said Dr. Van Beek. “He’s present, he’s devoted, and he’s typically the expert in the room.”
Dr. Harmon said that Dr. Resneck is “cut from the same cloth that I am. He believes that if you get an opportunity to make things better, you take it.”
His advice to Dr. Resneck: “Rarely turn an opportunity down.” Dr. Harmon has little doubt that Dr. Resneck is up to the job but said, “I’m going to encourage him to keep that energy and enthusiasm up.”
Dr. Resneck told physician colleagues not to worry: “I will keep relentlessly showing up.”

Thinking about taking on the AMA presidency, he said, “I’ve had some moments of trepidation. I wanted to be sure that I was going to be able to make a difference.”
Long interest in health policy
Growing up in Shreveport, La., as the son of a dermatologist, Dr. Resneck said, “at first, I swore I was going to do something other than medicine.” It was not out of rebellion. He got along fine with his father. He wanted to pursue his own journey.
Dr. Resneck began his long love affair with health policy at Brown University, graduating magna cum laude with honors in public policy. A 1991 U.S. Department of Health & Human Services internship between his junior and senior years helped inform his honors thesis on health care financing policy.
Ultimately, Dr. Resneck did not stray far from his father’s career path. While still at Brown, he decided to go to medical school, entering UCSF in the fall of 1993. “At the end of the day, there was this undeniable influence that he loved his job,” Dr. Resneck said in the interview. His father was energized by the work and helping patients. “If burnout was in his vocabulary, I never heard it,” said Dr. Resneck.
Initially, he did a 1-year internal medicine residency at UCSF, but then switched to dermatology and became chief resident in 2000.
He was quickly pegged as a leader and an inspirational speaker. The AAD gave him its Young Physician Leadership Development Award in 2001, and the AMA gave Dr. Resneck its Excellence in Medicine National Award for Young Physician Leadership in 2004. He began giving talks at national meetings in 2002 and has been busy ever since, addressing the AMA, the AAD, state medical and dermatology societies, subspecialty groups such as the American College of Mohs Surgery and the Association of Professors of Dermatology, and other organizations such as the American Telemedicine Association.
He’s a sought-after speaker in part because of his ability to simply communicate health policy, said Dr. Brod. “He can connect the real-world issues really well to the policy needs and communicate it very well, and come in at just the right level,” he said.
Dr. Resneck has been immersed in policy and practice issues since the start of his career, serving on AAD and AMA committees addressing quality measures, data collection, access to care, workforce issues, and telemedicine. He started writing about dermatology workforce challenges in 2001 and has revisited that topic with regularity.
He has published often on the difficulties of patient access, looking at wait times for appointments, among other issues. In 2018, he expressed concern in a commentary in JAMA Dermatology that private equity purchases of dermatology practices might lead to an improper focus on profits over patients and that it could reduce the diversity of practice models.
At heart, Dr. Resneck is an institutionalist, someone who believes that the “collaborative, collective voice can make change,” said Dr. Brod. Dr. Resneck said as much in his inaugural speech. “I believe those who show up can use levers of power to confront our system’s flaws,” he said. “This is the nerdy policy part of my life, which my friends will force me to admit is most of my life,” said Dr. Resneck.
Prior authorization, telemedicine, equity
Beneath the reserved exterior lies an intense yearning to act on his passions, both at work and at play.
Dr. Resneck notes almost in passing that he likes to ski when he’s not practicing medicine or serving on a committee. Dr. Van Beek – whose family has vacationed with Dr. Resneck, his wife, Ellen Hufbauer, MD, a family medicine physician in Concord, Calif., and their two teenaged children Zachary and Amelia – said he’s “a very good skier.”
She noted that he and his children share the same enthusiasm for researching every aspect of wherever they travel, including the best places to eat. “He embraces work and life with an incredible amount of intellectual curiosity,” Dr. Van Beek said.
That curiosity – and the passion to make a difference – has driven his deep dives into what he sees as the corrosive practice of prior authorization and the promise of telemedicine, which he has explained and supported in testimony on Capitol Hill.
Dr. Brod said that Dr. Resneck was among those who helped convince the federal government to expand coverage for telemedicine during the COVID-19 pandemic. “He brought together his patient experience in dermatology and his policy experience,” and was able to deftly explain how it could increase access during the shutdown, said Dr. Brod.
Prior authorization gets him fired up. “We’ve reached a point where there’s almost not anything I will write a prescription for that doesn’t oftentimes require all of these hoops that we have to jump through,” he told this news organization. Prescriptions for generic topical cortisones that have been around for 50 years “now all of the sudden require a week of arguing,” said Dr. Resneck. In the meantime, patients aren’t getting treatment, he said.
Dr. Resneck’s passion for health equity is borne in part out of the racism witnessed by him and his family, including an uncle who started an antisegregationist newspaper and was kicked out of medical school for his views in the 1950s. Dr. Resneck said he had a rudimentary understanding of racism as a youngster. But he told the AMA delegates, “I knew enough at age 16 to write an op-ed in our city’s newspaper about the need to remove Confederate monuments from our courthouse lawn.” Added Dr. Resneck, “You can imagine how that went over in 1987.”
The pandemic shined a bright light on inequities and heightened awareness of “the institutionalized systems that have perpetuated racism and gender discrimination in medicine for as far back as we want to look,” Dr. Resneck said during his inaugural speech. Pointedly, he told his colleagues that “the AMA has not always been on the right side of history,” adding, “Each of us must do our part to eliminate health inequities by engaging in antiracist and antisexist work.”
That kind of talk is signature Resneck, said Dr. Brod. “He’s not afraid to exhibit very brave leadership,” especially “when there are issues that jeopardize the needs of patient access or patient safety,” he said.
“He’ll be a tremendous AMA president,” said Dr. Van Beek. “He’s present, he’s devoted, and he’s typically the expert in the room.”
Dr. Harmon said that Dr. Resneck is “cut from the same cloth that I am. He believes that if you get an opportunity to make things better, you take it.”
His advice to Dr. Resneck: “Rarely turn an opportunity down.” Dr. Harmon has little doubt that Dr. Resneck is up to the job but said, “I’m going to encourage him to keep that energy and enthusiasm up.”
Dr. Resneck told physician colleagues not to worry: “I will keep relentlessly showing up.”

, more often on exposed skin. In the United States, Trichophyton rubrum, T. mentagrophytes, and Microsporum canis are the most common causal organisms. People can become infected from contact with other people, animals, or soil. Variants of tinea corporis include tinea imbricata (caused by T. concentricum), bullous tinea corporis, tinea gladiatorum (seen in wrestlers), tinea incognito (atypical tinea resulting from topical steroid use), and Majocchi’s granuloma. Widespread tinea may be secondary to underlying immunodeficiency such as HIV/AIDS or treatment with topical or oral steroids.
The typical presentation of tinea corporis is scaly erythematous or hypopigmented annular patches with a raised border and central clearing. In tinea imbricata, which is more commonly seen in southeast Asia, India, and Central America, concentric circles and serpiginous plaques are present. Majocchi’s granuloma has a deeper involvement of fungus in the hair follicles, presenting with papules and pustules at the periphery of the patches. Lesions of tinea incognito may lack a scaly border and can be more widespread.
Diagnosis can be confirmed with a skin scraping and potassium hydroxide (KOH) staining, which will reveal septate and branching hyphae. Biopsy is often helpful, especially in tinea incognito. Classically, a “sandwich sign” is seen: hyphae between orthokeratosis and compact hyperkeratosis or parakeratosis. In this patient, a biopsy from the left hip revealed dermatophytosis, with PAS positive for organisms.
Localized lesions respond to topical antifungal creams such as azoles or topical terbinafine. More extensive tinea will often require a systemic antifungal with griseofulvin, terbinafine, itraconazole, or fluconazole. This patient responded to topical ketoconazole cream and oral terbinafine. A workup for underlying immunodeficiency was negative.
