Ancient plague, cyclical pandemics … history lesson?
Even the plague wanted to visit Stonehenge
We’re about to blow your mind: The history you learned in school was often inaccurate. Shocking, we know, so we’ll give you a minute to process this incredible news.
Better? Good. Now, let’s look back at high school European history. The Black Death, specifically. The common narrative is that the Mongols, while besieging a Crimean city belonging to the Genoese, catapulted dead bodies infected with some mystery disease that turned out to be the plague. The Genoese then brought the plague back to Italy, and from there, we all know the rest of the story.
The Black Death was certainly extremely important to the development of modern Europe as we know it, but the history books gloss over the much longer history of the plague. Yersinia pestis did not suddenly appear unbidden in a Mongol war camp in 1347. The Black Death wasn’t even the first horrific, continent-wide pandemic caused by the plague; the Plague of Justinian 800 years earlier crippled the Byzantine Empire during an expansionist phase and killed anywhere between 15 million and 100 million.
Today, though, LOTME looks even deeper into history, nearly beyond even history itself, back into the depths of early Bronze Age northern Europe. Specifically, to two ancient burial sites in England, where researchers have identified three 4,000-year-old cases of Y. pestis, the first recorded incidence of the disease in Britain.
Two of the individuals, identified through analysis of dental pulp, were young children buried at a mass grave in Somerset, while the third, a middle-aged woman, was found in a ring cairn in Cumbria. These sites are hundreds of miles apart, yet carbon dating suggests all three people lived and died at roughly the same time. The strain found is very similar to other samples of plague found across central and western Europe starting around 3,000 BCE, suggesting a single, easily spread disease affecting a large area in a relatively small period of time. In other words, a pandemic. Even in these ancient times, the world was connected. Not even the island of Britain could escape.
Beyond that though, the research helps confirm the cyclical nature of the plague; over time, it loses its effectiveness and goes into hiding, only to mutate and come roaring back. This is a story with absolutely no relevance at all to the modern world. Nope, no plagues or pandemics going around right now, no viruses fading into the background in any way. What a ridiculous inference to make.
Uncovering the invisible with artificial intelligence
This week in “What Else Can AI Do?” new research shows that a computer program can reveal brain injury that couldn’t be seen before with typical MRI.
The hot new AI, birthed by researchers at New York University, could potentially be a game changer by linking repeated head impacts with tiny, structural changes in the brains of athletes who have not been diagnosed with a concussion. By using machine learning to train the AI, the researchers were, for the first time, able to distinguish the brain of athletes who played contact sports (football, soccer, lacrosse) from those participating in noncontact sports such as baseball, basketball, and cross-country.
How did they do it? The investigators “designed statistical techniques that gave their computer program the ability to ‘learn’ how to predict exposure to repeated head impacts using mathematical models,” they explained in a written statement. Adding in data from the MRI scans of 81 male athletes with no known concussion diagnosis and the ability to identify unusual brain features between athletes with and without head trauma allowed the AI to predict results with accuracy even Miss Cleo would envy.
“This method may provide an important diagnostic tool not only for concussion, but also for detecting the damage that stems from subtler and more frequent head impacts,” said lead author Junbo Chen, an engineering doctoral candidate at NYU. That could make this new AI a valuable asset to science and medicine.
There are many things the human brain can do that AI can’t, and delegation could be one of them. Examining the data that represent the human brain in minute detail? Maybe we leave that to the machine.

If you’re a surgeon doing an amputation, the list of possible assistants pretty much starts and ends in only one place: Not the closest available janitor.
That may seem like an oddly obvious thing for us to say, but there’s at least one former Mainz (Germany) University Hospital physician who really needed to get this bit of advice before he attempted an unassisted toe amputation back in October of 2020. Yes, that does seem like kind of a long time ago for us to be reporting it now, but the details of the incident only just came to light a few days ago, thanks to German public broadcaster SWR.
Since it was just a toe, the surgeon thought he could perform the operation without any help. The toe, unfortunately, had other plans. The partially anesthetized patient got restless in the operating room, but with no actual trained nurse in the vicinity, the surgeon asked the closest available person – that would be the janitor – to lend a hand.
The surgical manager heard about these goings-on and got to the operating room too late to stop the procedure but soon enough to see the cleaning staffer “at the operating table with a bloody suction cup and a bloody compress in their hands,” SWR recently reported.
The incident was reported to the hospital’s medical director and the surgeon was fired, but since the patient experienced no complications not much fuss was made about it at the time.
Well, guess what? It’s toe-tally our job to make a fuss about these kinds of things. Or could it be that our job, much like the surgeon’s employment and the patient’s digit, is here toe-day and gone toe-morrow?

Adult tonsillectomies work and they’re cost effective
A new randomized trial offers rare insight into outcomes in adult tonsillectomy, a surgical procedure that’s commonly performed in the United States yet falling out of favor. Tonsillectomies are both clinically effective and cost-effective in adult patients with recurrent acute tonsillitis, a British team reports.
The researchers declined to weigh in on whether the procedure is actually better than nonsurgical management. Still, “here at last, we have a substantial piece of scientific evidence which shows that, compared with nonsurgical management, removal of tonsils has a significant impact on the number of sore throat days and on the cost of managing sore throat disease in adults,” said study lead author Janet A. Wilson, MBChB, MD, an emerita professor of otolaryngology at Newcastle University (England), in an interview.
The study was published in The Lancet.
Tonsillectomies have become much less common over the past several decades as questions have arisen about their value. In the United States, the number of procedures performed each year plunged from a high of 1.4 million in 1959 to an estimated 286,000 tonsillectomies performed in children under 15 and 120,000 in people aged 15 in 2010.
It’s harder for adults to tolerate tonsillectomies than children, Dr. Wilson said. In children, surgeons can easily remove tonsils by scraping them off the throat’s side walls. But, she said, “an adult tonsillectomy is more akin to taking off the skin of an unripe orange, so it’s harder work for the surgeon and more traumatizing for the wall of the adult patient’s pharynx. We can only assume that this greater amount of fibrous tissue reflects the cumulative effect of infections over a period of years.”
While tonsillectomies are still performed hundreds of times a day in adults in the United States, a 2014 Cochrane Library review found there’s “insufficient information “to support them versus nonsurgical care as treatments to reduce sore throats.”
For the new multicenter, open-label, randomized study, researchers randomly assigned patients aged 16 and older with recurrent acute tonsillitis to immediate tonsillectomy or nonsurgical management, which Dr. Wilson said can include cold fluids, honey, analgesics/anti-inflammatories. and anesthetic throat lozenges. The study was conducted between 2015 and 2018.
Ultimately, there were 224 and 204 patients, respectively, in the two groups (average age = 23, [19-30], 78% female, 90% White).
Patients who underwent tonsillectomies versus nonsurgical treatment had fewer sore throats over 2 years (median 23 days [IQR 11-46 days] vs. 30 days [14-65 days]) with an incident rate ratio of 0.53 (95% confidence interval, 0.43-0.65, P < 0.0001) after adjustment for clinic site and baseline severity.
The study also shows that “adults who have severe recurrent throat infections with a frequency of seven episodes within 1 year, five or more for 2 consecutive years, or three or more in 3 consecutive years will suffer fewer days of sore throat in the 2 years following tonsillectomy than if they had kept their tonsils,” Dr. Wilson said.
The study doesn’t examine longer-term consequences. A 2018 study of children linked tonsillectomies to “significantly increased relative risk of later respiratory, allergic, and infectious diseases.”
In the new study, nearly 4 in 10 (39%) of the tonsillectomy patients had adverse events linked to the surgeries, and bleeding (19%) was the most common adverse effect. The researchers also estimated that “tonsillectomy has a high probability of being considered cost-effective.”
“Whichever way the results were analyzed and confounding variables allowed for, the result always seems to be the same: Tonsillectomy applied using current qualifying criteria was a worthwhile procedure,” Dr. Wilson said.
Dr. Wilson noted that tonsillectomy patients will suffer a persistent sore throat after surgery, “about the same as a bad episode of tonsillitis.” And she said patients will need to adjust their diet for a few days and take 1-2 weeks off work.
In an interview, internal medicine physician Noel Deep, MD, of Antigo, Wisc., said antibiotics are a common treatment for tonsillitis in primary care clinics. According to him, the United States doesn’t have guidelines for tonsillectomies in adults. He believes they can be considered if tonsillitis keeps recurring three to five times a year and disrupts quality of life.
Dr. Deep said the new study “reinforces the benefit of tonsillectomies. Several studies from Germany, Sweden, Finland, and the United Kingdom have demonstrated benefits of tonsillectomies, but they were only for short periods of less than a year and lacked long-term data.”
He noted that “there is no clear evidence as to when to recommend tonsillectomies.” Clinicians should talk to patients about the potential that tonsillectomies will reduce sore throat episodes and cost the patient less in the long run, he said. It’s also important, he said, to make sure tonsillitis is bacterial before prescribing antibiotics.
The United Kingdom’s National Institute for Health Research funded the study. Dr. Wilson disclosed support for meetings/travel from ENT Scotland, and the other authors report various disclosures, including grants and contracts. Dr. Deep serves on the editorial advisory board of Internal Medicine News and is chair of the American Medical Association Council on Science and Public Health.

FROM THE LANCET
Papular Acneform Eruption With Mucositis
The Diagnosis: Syphilis
Histopathology revealed psoriasiform hyperplasia, endothelial cell swelling, and a brisk lichenoid inflammation with plasma cells (Figure, A). There also was pustular folliculitis in association with well-formed granulomatous inflammation and a prominent number of plasma cells (Figure, B). Treponema pallidum immunostaining showed numerous organisms in the epidermal and follicular epithelium. Rapid plasma reagin was found to be positive with a titer of 1:128. Evaluation for neurosyphilis through lumbar puncture was negative; the patient also was HIV negative. All of our patient’s skin lesions cleared after a 3-week course of weekly intramuscular benzathine G injections. Due to his substantial clinical improvement, the patient was subsequently lost to follow-up.
Syphilis, an infectious disease caused by the spirochete bacterium T pallidum, has a well-known natural history defined by various stages classically categorized as primary, secondary, latent, or late (tertiary).1 The classic lesion in primary syphilis is the chancre, a painless ulcer with raised borders that develops within approximately 3 weeks following the initial inoculation.2 Secondary syphilis manifests with mucocutaneous findings in up to 97% of patients, and untreated patients develop secondary syphilis at a rate of approximately 25%.3 Although mucocutaneous findings in secondary syphilis can vary widely, patients most commonly develop a diffuse maculopapular exanthem, and 40% develop mucosal findings including genital ulcers, mucous patches, and condylomata lata.1 In latent syphilis, there is seroreactivity, but otherwise there are no clinical symptoms. A clear symptomatic history of prior primary or secondary syphilis may be known or unknown. Latent syphilis is divided into early and late phases, and the World Health Organization designates 2 years after the first suspected exposure as the cutoff point for early and late latency.4 During the first 4 years of latent syphilis, patients may exhibit mucocutaneous relapses. Our patient denied any sexual activity for more than 3 years prior to presentation. Because of the start of iatrogenic immunosuppression during this period, this case was classified as late latent syphilis with mucocutaneous reactivation.
Behçet disease was included within the differential diagnosis but is characterized by multiorgan systemic vasculitis that causes various mucocutaneous findings including aphthous ulcers, papulopustular lesions, and genital ulcers.5 Histopathologic features are nonspecific, and the clinical finding of recurrent genital and oral ulceration should be present for diagnosis. This disease predominantly occurs in East Asian or Mediterranean populations and is otherwise rare in White individuals.
SAPHO (synovitis, acne, pustulosis, hyperostosis, osteitis) syndrome is a rare disorder consisting of skin, joint, and bone manifestations.6 Severe acne generally is accompanied by palmoplantar pustulosis along with pain and joint tenderness involving the anterior chest and axial skeleton, both of which were absent in our patient.
Pustular psoriasis can be localized or generalized. Localized presentations frequently are acral and may be associated with a variable degree of nail dystrophy and arthritis. Generalized presentations are characterized by hyperemic, well-defined patches with variable numbers of pustules.7 The pustules are the consequence of exuberate neutrophilic exocytosis into the epidermis and are nonfollicular.
Steroid-induced acne may be considered in the proper clinical setting of an acneform eruption with a prior history of systemic steroid treatment. However, additional findings of mucositis would not be expected, and although our patient was prescribed prednisone from his primary care physician prior to presentation to our clinic, this medication was given after the onset of the cutaneous eruption.
Syphilis commonly is referred to as the great mimicker due to its potential diverse morphologic presentations, which can involve acneform eruptions, though rare.8 In the setting of mucositis, generalized acneform eruptions should raise suspicion for the possibility of syphilis, even in the absence of other more classic cutaneous features.

The Diagnosis: Syphilis
Histopathology revealed psoriasiform hyperplasia, endothelial cell swelling, and a brisk lichenoid inflammation with plasma cells (Figure, A). There also was pustular folliculitis in association with well-formed granulomatous inflammation and a prominent number of plasma cells (Figure, B). Treponema pallidum immunostaining showed numerous organisms in the epidermal and follicular epithelium. Rapid plasma reagin was found to be positive with a titer of 1:128. Evaluation for neurosyphilis through lumbar puncture was negative; the patient also was HIV negative. All of our patient’s skin lesions cleared after a 3-week course of weekly intramuscular benzathine G injections. Due to his substantial clinical improvement, the patient was subsequently lost to follow-up.
Syphilis, an infectious disease caused by the spirochete bacterium T pallidum, has a well-known natural history defined by various stages classically categorized as primary, secondary, latent, or late (tertiary).1 The classic lesion in primary syphilis is the chancre, a painless ulcer with raised borders that develops within approximately 3 weeks following the initial inoculation.2 Secondary syphilis manifests with mucocutaneous findings in up to 97% of patients, and untreated patients develop secondary syphilis at a rate of approximately 25%.3 Although mucocutaneous findings in secondary syphilis can vary widely, patients most commonly develop a diffuse maculopapular exanthem, and 40% develop mucosal findings including genital ulcers, mucous patches, and condylomata lata.1 In latent syphilis, there is seroreactivity, but otherwise there are no clinical symptoms. A clear symptomatic history of prior primary or secondary syphilis may be known or unknown. Latent syphilis is divided into early and late phases, and the World Health Organization designates 2 years after the first suspected exposure as the cutoff point for early and late latency.4 During the first 4 years of latent syphilis, patients may exhibit mucocutaneous relapses.

A 48-year-old man with a history of ulcerative colitis that was well-controlled with adalimumab presented with a generalized acneform eruption involving the face, chest (top) and back, as well as a well-defined ovoid ulcer on the anterior aspect of the tongue (bottom) of 2 months’ duration. Prior treatment with prednisone 60 mg daily for 14 days resulted in no improvement. He denied unintentional weight loss, cyclic fever, or arthritis. A complete blood cell count with differential showed mild anemia (hemoglobin, 11.6 g/dL [reference range, 13.2–16.6 g/dL]) with a differential cell count that was within reference range for each cell type. The erythrocyte sedimentation rate was elevated at 44 mm/h (reference range, 0–22 mm/h). A 4-mm punch biopsy specimen of an indurated cystic papule on the torso was obtained.
CDC warns of Mpox resurgence in summer of 2023
A resurgence of mpox this summer could be larger than last year’s caseload, the Centers for Disease Control and Prevention said in a warning to public health officials this week.
“The outbreak is not over,” the CDC alert stated, noting that springtime and summertime gatherings and festivals could lead to renewed virus spread. A new cluster of 13 cases is being investigated in Chicago, all among men, and four among people who recently traveled to New York City, New Orleans, or Mexico.
Mpox, formerly called monkeypox, is a virus that causes a rash and sometimes flulike symptoms. It is most often transmitted through sexual contact, but it can also be spread in nonsexual ways that involve contact with skin lesions or with saliva or upper respiratory secretions like snot or mucus, the CDC says. Most cases in the United States have been among gay or bisexual men, men who have sex with men, and transgender people.
Last year, the U.S. government declared mpox a public health emergency as cases peaked at 460 per day in August, infecting more than 30,000 people and killing 42 people. Public health officials worked to quickly distribute vaccinations to people at high risk for contracting the virus. The CDC says 23% of people most at risk of getting mpox have been vaccinated.
Vaccination does not necessarily prevent infection but can lessen the severity of symptoms. Nine of the men who were recently infected in Chicago were fully vaccinated.
“It’s important to remember that vaccines, while incredibly helpful, are not our only way to reduce the risk of contracting mpox,” Richard Silvera, MD, MPH, of the department of infectious diseases at Icahn School of Medicine at Mount Sinai, New York, told ABC News.
Other ways to reduce risk are “things like avoiding social and sexual contact if you have new skin lesions and asking your intimate contacts if they are experiencing symptoms or new skin changes,” Dr. Silvera said.

The antimicrobial peptide that even Pharma can love
Fastest peptide north, south, east, aaaaand west of the Pecos
Bacterial infections are supposed to be simple. You get infected, you get an antibiotic to treat it. Easy. Some bacteria, though, don’t play by the rules. Those antibiotics may kill 99.9% of germs, but what about the 0.1% that gets left behind? With their fallen comrades out of the way, the accidentally drug resistant species are free to inherit the Earth.
Antibiotic resistance is thus a major concern for the medical community. Naturally, anything that prevents doctors from successfully curing sick people is a priority. Unless you’re a major pharmaceutical company that has been loath to develop new drugs that can beat antibiotic-resistant bacteria. Blah blah, time and money, blah blah, long time between development and market application, blah blah, no profit. We all know the story with pharmaceutical companies.
Research from other sources has continued, however, and Brazilian scientists recently published research involving a peptide known as plantaricin 149. This peptide, derived from the bacterium Lactobacillus plantarum, has been known for nearly 30 years to have antibacterial properties. Pln149 in its natural state, though, is not particularly efficient at bacteria-killing. Fortunately, we have science and technology on our side.
The researchers synthesized 20 analogs of Pln149, of which Pln149-PEP20 had the best results. The elegantly named compound is less than half the size of the original peptide, less toxic, and far better at killing any and all drug-resistant bacteria the researchers threw at it. How much better? Pln149-PEP20 started killing bacteria less than an hour after being introduced in lab trials.
The research is just in its early days – just because something is less toxic doesn’t necessarily mean you want to go and help yourself to it – but we can only hope that those lovely pharmaceutical companies deign to look down upon us and actually develop a drug utilizing Pln149-PEP20 to, you know, actually help sick people, instead of trying to build monopolies or avoiding paying billions in taxes. Yeah, we couldn’t keep a straight face through that last sentence either.
Speed healing: The wavy wound gets the swirl
Did you know that wavy wounds heal faster than straight wounds? Well, we didn’t, but apparently quite a few people did, because somebody has been trying to figure out why wavy wounds heal faster than straight ones. Do the surgeons know about this? How about you dermatologists? Wavy over straight? We’re the media. We’re supposed to report this kind of stuff. Maybe hit us with a tweet next time you do something important, or push a TikTok our way, okay?
You could be more like the investigators at Nanyang Technological University in Singapore, who figured out the why and then released a statement about it.
They created synthetic wounds – some straight, some wavy – in micropatterned hydrogel substrates that mimicked human skin. Then they used an advanced optical technique known as particle image velocimetry to measure fluid flow and learn how cells moved to close the wound gaps.
The wavy wounds “induced more complex collective cell movements, such as a swirly, vortex-like motion,” according to the written statement from NTU Singapore. In the straight wounds, cell movements paralleled the wound front, “moving in straight lines like a marching band,” they pointed out, unlike some researchers who never call us unless they need money.
Complex epithelial cell movements are better, it turns out. Over an observation period of 64 hours the NTU team found that the healing efficiency of wavy gaps – measured by the area covered by the cells over time – is nearly five times faster than straight gaps.
The complex motion “enabled cells to quickly connect with similar cells on the opposite site of the wound edge, forming a bridge and closing the wavy wound gaps faster than straight gaps,” explained lead author Xu Hongmei, a doctoral student at NTU’s School of Mechanical and Aerospace Engineering, who seems to have time to toss out a tumblr or two to keep the press informed.
As for the rest of you, would it kill you to pick up a phone once in a while? Maybe let a journalist know that you’re still alive? We have feelings too, you know, and we worry.
A little Jekyll, a little Hyde, and a little shop of horrors
More “Little Shop of Horrors” references are coming, so be prepared.
We begin with Triphyophyllum peltatum. This woody vine is of great interest to medical and pharmaceutical researchers because its constituents have shown promise against pancreatic cancer and leukemia cells, among others, along with the pathogens that cause malaria and other diseases. There is another side, however. T. peltatum also has a tendency to turn into a realistic Audrey II when deprived.
No, of course they’re not craving human flesh, but it does become … carnivorous in its appetite.
T. peltatum, native to the West African tropics and not found in a New York florist shop, has the unique ability to change its diet and development based on the environmental circumstances. For some unknown reason, the leaves would develop adhesive traps in the form of sticky drops that capture insect prey. The plant is notoriously hard to grow, however, so no one could study the transformation under lab conditions. Until now.
A group of German scientists “exposed the plant to different stress factors, including deficiencies of various nutrients, and studied how it responded to each,” said Dr. Traud Winkelmann of Leibniz University Hannover. “Only in one case were we able to observe the formation of traps: in the case of a lack of phosphorus.”
Well, there you have it: phosphorus. We need it for healthy bones and teeth, which this plant doesn’t have to worry about, unlike its Tony Award–nominated counterpart. The investigators hope that their findings could lead to “future molecular analyses that will help understand the origins of carnivory,” but we’re guessing that a certain singing alien species will be left out of that research.

Well, we didn’t, but apparently quite a few people did, because somebody has been trying to figure out why wavy wounds heal faster than straight ones. Do the surgeons know about this? How about you dermatologists? Wavy over straight? We’re the media. We’re supposed to report this kind of stuff. Maybe hit us with a tweet next time you do something important, or push a TikTok our way, okay?
You could be more like the investigators at Nanyang Technological University in Singapore, who figured out the why and then released a statement about it.
They created synthetic wounds – some straight, some wavy – in micropatterned hydrogel substrates that mimicked human skin. Then they used an advanced optical technique known as particle image velocimetry to measure fluid flow and learn how cells moved to close the wound gaps.
The wavy wounds “induced more complex collective cell movements, such as a swirly, vortex-like motion,” according to the written statement from NTU Singapore. In the straight wounds, cell movements paralleled the wound front, “moving in straight lines like a marching band,” they pointed out, unlike some researchers who never call us unless they need money.
Complex epithelial cell movements are better, it turns out. Over an observation period of 64 hours the NTU team found that the healing efficiency of wavy gaps – measured by the area covered by the cells over time – is nearly five times faster than straight gaps.
The complex motion “enabled cells to quickly connect with similar cells on the opposite site of the wound edge, forming a bridge and closing the wavy wound gaps faster than straight gaps,” explained lead author Xu Hongmei, a doctoral student at NTU’s School of Mechanical and Aerospace Engineering, who seems to have time to toss out a tumblr or two to keep the press informed.
As for the rest of you, would it kill you to pick up a phone once in a while? Maybe let a journalist know that you’re still alive? We have feelings too, you know, and we worry.
A little Jekyll, a little Hyde, and a little shop of horrors
More “Little Shop of Horrors” references are coming, so be prepared.
We begin with Triphyophyllum peltatum. This woody vine is of great interest to medical and pharmaceutical researchers because its constituents have shown promise against pancreatic cancer and leukemia cells, among others, along with the pathogens that cause malaria and other diseases. There is another side, however. T. peltatum also has a tendency to turn into a realistic Audrey II when deprived.
No, of course they’re not craving human flesh, but it does become … carnivorous in its appetite.
T. peltatum, native to the West African tropics and not found in a New York florist shop, has the unique ability to change its diet and development based on the environmental circumstances. For some unknown reason, the leaves would develop adhesive traps in the form of sticky drops that capture insect prey. The plant is notoriously hard to grow, however, so no one could study the transformation under lab conditions. Until now.
A group of German scientists “exposed the plant to different stress factors, including deficiencies of various nutrients, and studied how it responded to each,” said Dr. Traud Winkelmann of Leibniz University Hannover. “Only in one case were we able to observe the formation of traps: in the case of a lack of phosphorus.”
Well, there you have it: phosphorus. We need it for healthy bones and teeth, which this plant doesn’t have to worry about, unlike its Tony Award–nominated counterpart. The investigators hope that their findings could lead to “future molecular analyses that will help understand the origins of carnivory,” but we’re guessing that a certain singing alien species will be left out of that research.
CDC: Drug-resistant ringworm reported in New York
BY ALICIA AULT
The in New York.
Tinea, or ringworm, one of the most common fungal infections, is responsible for almost 5 million outpatient visits and 690 hospitalizations annually, according to the CDC.
Over the past 10 years, severe, antifungal-resistant tinea has spread in South Asia, in part because of the rise of a new dermatophyte species known as Trichophyton indotineae, wrote the authors of a report on the two patients with the drug-resistant strain. This epidemic “has likely been driven by misuse and overuse of topical antifungals and corticosteroids,” added the authors, in Morbidity and Mortality Weekly Report.
The cases were detected by a New York City dermatologist. In the first case, a 28-year-old woman developed a widespread pruritic eruption in the summer of 2021. She did not consult a dermatologist until December, when she was in the third trimester of pregnancy. She had large, annular, scaly, pruritic plaques on her neck, abdomen, pubic region, and buttocks, but had no underlying medical conditions, no known exposures to someone with a similar rash, and no recent international travel history.
After she gave birth in January, she started oral terbinafine therapy but had no improvement after 2 weeks. Clinicians administered a 4-week course of itraconazole, which resolved the infection.
The second patient, a 47-year-old woman with no medical conditions, developed a rash while in Bangladesh in the summer of 2022. Other family members had a similar rash. She was treated with topical antifungal and steroid combination creams but had no resolution. Back in the United States, she was prescribed hydrocortisone 2.5% ointment and diphenhydramine, clotrimazole cream, and terbinafine cream in three successive emergency department visits. In December 2022, dermatologists, observing widespread, discrete, scaly, annular, pruritic plaques on the thighs and buttocks, prescribed a 4-week course of oral terbinafine. When the rash did not resolve, she was given 4 weeks of griseofulvin. The rash persisted, although there was 80% improvement. Clinicians are now considering itraconazole. The woman’s son and husband are also being evaluated, as they have similar rashes.
In both cases, skin culture isolates were initially identified as Trichophyton mentagrophytes. Further analysis at the New York State Department of Health’s lab, using Sanger sequencing of the internal transcribed spacer region of the ribosomal gene, followed by phylogenetic analysis, identified the isolates as T. indotineae.
The authors note that culture-based techniques used by most clinical laboratories typically misidentify T. indotineae as T. mentagrophytes or T. interdigitale. Genomic sequencing must be used to properly identify T. indotineae, they wrote.
Clinicians should consider T. indotineae in patients with widespread ringworm, especially if they do not improve with topical antifungals or oral terbinafine, said the authors. If T. indotineae is suspected, state or local public health departments can direct clinicians to testing.
The authors report no relevant financial relationships.

A healthy 36-year-old female presented with 4 days of itchy lesions on the right upper extremity
Additionally, Orthopox DNA by PCR and Monkeypox (mpox) virus DNA by PCR were detected. Herpes simplex virus and bacterial viral cultures were negative. Valacyclovir was started at the time of presentation and the patient’s lesions resolved without sequelae.
Mpox is a zoonotic double-stranded DNA virus that is part of the Orthopoxvirus family, including the West African and Central African variants. This disease presents similarly to smallpox, so most mpox research was conducted around the time smallpox was eradicated. It was not until 1970, when the disease was isolated from a patient with suspected smallpox in the Democratic Republic of the Congo (DRC), that human mpox was considered a distinct disease. An epidemic outbreak in the United States occurred in 2003 related to infected prairie dogs, and travel-related outbreaks have been more recently reported up until May 2022, in which mpox was reported in nonendemic areas including North America, Europe, and Australia. Most cases in this outbreak occurred in men who have sex with men (MSM), but this is not always the case, and mpox is not necessarily considered a sexually transmitted infection. Mpox presents similarly to smallpox and VZV, so using laboratory tests is important in diagnosing and tracking this disease.
Although it is not easily transmitted, the disease can spread through bodily secretions both directly and indirectly. Mpox typically begins with a prodrome that includes fever, headache, myalgia, and fatigue. This is followed by lymphadenopathy that precedes and coincides with rash development. The lymph nodes are firm, tender, may be painful, and are a defining factor in presentation that differs from smallpox and varicella. The rash typically starts on the face, then presents on the body in a centrifugal distribution. However, cases related to sexual transmission present with anogenital lesions. The lesions are characterized by a progression from maculopapular to vesiculopustular, and can vary widely in quantity.
Notably, individuals are contagious from the onset of the prodrome until the lesions have scabbed over and fallen off. The eruptive nature of the later lesions poses a threat of secondary infection, and is often accompanied by a second febrile period that signifies deterioration of the patient’s condition. Other signs of secondary infection are variable and include pulmonary symptoms, vomiting, diarrhea, ocular infections, and in rare cases, encephalitis. These sequelae are more common in unvaccinated and immunocompromised individuals. Long-term complications of mpox include pitted scarring from cutaneous lesions with children being more susceptible to severe disease. The mortality rate for the disease is very low. (As of May 10, 2023, there have been 30,395 mpox cases reported in the United States, and 42 deaths, according to the Centers for Disease Control and Prevention.)
There are a variety of diagnostic tests that can aid in mpox identification, but they are most strongly supported when combined with clinical and epidemiological data. The best, least invasive method includes collection of lesion exudate or crust on a swab, and viral DNA is best preserved by keeping the specimen in a cool, dry, and dark environment. PCR is considered the standard, and electron microscopy and immunohistochemistry are valid tests, but all modalities require sophisticated technicians with the proper laboratory equipment. This is limiting because many cases present in underserved areas that lack the facilities for proper, real-time analysis. Antigen and antibody-based tests can be used, but cross-reactivity of other orthopoxviridae limits confirmation of mpox infection. Vaccination status, history and location must be considered.
Vaccination is the chief form of prevention for mpox, although it is not considered entirely protective. Smallpox vaccination provides protection, but widespread administration of the vaccine is no longer practiced, and an estimated 70% of the global population is no longer vaccinated. Vaccination is recommended for anyone at risk of exposure, but as this is a live, attenuated vaccine, the immune status of the patient is important to keep in mind. Tecovirimat and other antiviral medications including cidofovir and brincidofovir may be considered in severe cases.
This case is unique as our patient, who had no known risk factors for mpox, presented with mpox and VZV, simultaneously. Although clinical presentation and epidemiological patterns between these diseases differ, there have been a limited number of cases of coinfection reported in the literature, mainly in the DRC where mpox is endemic. Diagnosis must be made by separate laboratory tests and there are differences in presentation between independent and coinfection for these viruses. Notably, patients with mpox/VZV coinfection may be less likely to present with lesions on the face, thorax, arms, palms, and soles than those with only mpox but experience a higher lesion burden than those afflicted by only VZV. Coinfection may be related to reactivation of dormant VZV, or increased susceptibility to secondary infection when infected with one virus.

Boys may carry the weight, or overweight, of adults’ infertility
Overweight boy, infertile man?
When it comes to causes of infertility, history and science have generally focused on women. A lot of the research overlooks men, but some previous studies have suggested that male infertility contributes to about half of the cases of couple infertility. The reason for much of that male infertility, however, has been a mystery. Until now.
A group of Italian investigators looked at the declining trend in sperm counts over the past 40 years and the increase of childhood obesity. Is there a correlation? The researchers think so. Childhood obesity can be linked to multiple causes, but the researchers zeroed in on the effect that obesity has on metabolic rates and, therefore, testicular growth.
Collecting data on testicular volume, body mass index (BMI), and insulin resistance from 268 boys aged 2-18 years, the researchers discovered that those with normal weight and normal insulin levels had testicular volumes 1.5 times higher than their overweight counterparts and 1.5-2 times higher than those with hyperinsulinemia, building a case for obesity being a factor for infertility later in life.
Since low testicular volume is associated with lower sperm count and production as an adult, putting two and two together makes a compelling argument for childhood obesity being a major male infertility culprit. It also creates even more urgency for the health care industry and community decision makers to focus on childhood obesity.
It sure would be nice to be able to take one of the many risk factors for future human survival off the table. Maybe by taking something, like cake, off the table.
Fecal transplantation moves to the kitchen
Fecal microbiota transplantation is an effective way to treat Clostridioides difficile infection, but, in the end, it’s still a transplantation procedure involving a nasogastric or colorectal tube or rather large oral capsules with a demanding (30-40 capsules over 2 days) dosage. Please, Science, tell us there’s a better way.
Science, in the form of investigators at the University of Geneva and Lausanne University Hospital in Switzerland, has spoken, and there may be a better way. Presenting fecal beads: All the bacterial goodness of donor stool without the tubal insertions or massive quantities of giant capsules.
We know you’re scoffing out there, but it’s true. All you need is a little alginate, which is a “biocompatible polysaccharide isolated from brown algae” of the Phaeophyceae family. The donor feces is microencapsulated by mixing it with the alginate, dropping that mixture into water containing calcium chloride, turning it into a gel, and then freeze-drying the gel into small (just 2 mm), solid beads.
Sounds plausible enough, but what do you do with them? “These brownish beads can be easily dispersed in a liquid or food that is pleasant to eat. They also have no taste,” senior author Eric Allémann, PhD, said in a statement released by the University of Geneva.
Pleasant to eat? No taste? So which is it? If you really want to know, watch fecal beads week on the new season of “The Great British Baking Show,” when Paul and Prue judge poop baked into crumpets, crepes, and crostatas. Yum.
We’re on the low-oxygen diet
Nine out of ten doctors agree: Oxygen is more important to your continued well-being than food. After all, a human can go weeks without food, but just minutes without oxygen. However, ten out of ten doctors agree that the United States has an obesity problem. They all also agree that previous research has shown soldiers who train at high altitudes lose more weight than those training at lower altitudes.
So, on the one hand, we have a country full of overweight people, and on the other, we have low oxygen levels causing weight loss. The solution, then, is obvious: Stop breathing.
More specifically (and somewhat less facetiously), researchers from Louisiana have launched the Low Oxygen and Weight Status trial and are currently recruiting individuals with BMIs of 30-40 to, uh, suffocate themselves. No, no, it’s okay, it’s just when they’re sleeping.
Fine, straight face. Participants in the LOWS trial will undergo an 8-week period when they will consume a controlled weight-loss diet and spend their nights in a hypoxic sealed tent, where they will sleep in an environment with an oxygen level equivalent to 8,500 feet above sea level (roughly equivalent to Aspen, Colo.). They will be compared with people on the same diet who sleep in a normal, sea-level oxygen environment.
The study’s goal is to determine whether or not spending time in a low-oxygen environment will suppress appetite, increase energy expenditure, and improve weight loss and insulin sensitivity. Excessive weight loss in high-altitude environments isn’t a good thing for soldiers – they kind of need their muscles and body weight to do the whole soldiering thing – but it could be great for people struggling to lose those last few pounds. And it also may prove LOTME’s previous thesis: Air is not good.

Collecting data on testicular volume, body mass index (BMI), and insulin resistance from 268 boys aged 2-18 years, the researchers discovered that those with normal weight and normal insulin levels had testicular volumes 1.5 times higher than their overweight counterparts and 1.5-2 times higher than those with hyperinsulinemia, building a case for obesity being a factor for infertility later in life.
Since low testicular volume is associated with lower sperm count and production as an adult, putting two and two together makes a compelling argument for childhood obesity being a major male infertility culprit. It also creates even more urgency for the health care industry and community decision makers to focus on childhood obesity.
It sure would be nice to be able to take one of the many risk factors for future human survival off the table. Maybe by taking something, like cake, off the table.
Fecal transplantation moves to the kitchen
Fecal microbiota transplantation is an effective way to treat Clostridioides difficile infection, but, in the end, it’s still a transplantation procedure involving a nasogastric or colorectal tube or rather large oral capsules with a demanding (30-40 capsules over 2 days) dosage. Please, Science, tell us there’s a better way.
Science, in the form of investigators at the University of Geneva and Lausanne University Hospital in Switzerland, has spoken, and there may be a better way. Presenting fecal beads: All the bacterial goodness of donor stool without the tubal insertions or massive quantities of giant capsules.
We know you’re scoffing out there, but it’s true. All you need is a little alginate, which is a “biocompatible polysaccharide isolated from brown algae” of the Phaeophyceae family. The donor feces is microencapsulated by mixing it with the alginate, dropping that mixture into water containing calcium chloride, turning it into a gel, and then freeze-drying the gel into small (just 2 mm), solid beads.
Sounds plausible enough, but what do you do with them? “These brownish beads can be easily dispersed in a liquid or food that is pleasant to eat. They also have no taste,” senior author Eric Allémann, PhD, said in a statement released by the University of Geneva.
Pleasant to eat? No taste? So which is it? If you really want to know, watch fecal beads week on the new season of “The Great British Baking Show,” when Paul and Prue judge poop baked into crumpets, crepes, and crostatas. Yum.
We’re on the low-oxygen diet
Nine out of ten doctors agree: Oxygen is more important to your continued well-being than food. After all, a human can go weeks without food, but just minutes without oxygen. However, ten out of ten doctors agree that the United States has an obesity problem. They all also agree that previous research has shown soldiers who train at high altitudes lose more weight than those training at lower altitudes.
So, on the one hand, we have a country full of overweight people, and on the other, we have low oxygen levels causing weight loss. The solution, then, is obvious: Stop breathing.
More specifically (and somewhat less facetiously), researchers from Louisiana have launched the Low Oxygen and Weight Status trial and are currently recruiting individuals with BMIs of 30-40 to, uh, suffocate themselves. No, no, it’s okay, it’s just when they’re sleeping.
Fine, straight face. Participants in the LOWS trial will undergo an 8-week period when they will consume a controlled weight-loss diet and spend their nights in a hypoxic sealed tent, where they will sleep in an environment with an oxygen level equivalent to 8,500 feet above sea level (roughly equivalent to Aspen, Colo.). They will be compared with people on the same diet who sleep in a normal, sea-level oxygen environment.
The study’s goal is to determine whether or not spending time in a low-oxygen environment will suppress appetite, increase energy expenditure, and improve weight loss and insulin sensitivity. Excessive weight loss in high-altitude environments isn’t a good thing for soldiers – they kind of need their muscles and body weight to do the whole soldiering thing – but it could be great for people struggling to lose those last few pounds. And it also may prove LOTME’s previous thesis: Air is not good.
Overweight boy, infertile man?
When it comes to causes of infertility, history and science have generally focused on women. A lot of the research overlooks men, but some previous studies have suggested that male infertility contributes to about half of the cases of couple infertility. The reason for much of that male infertility, however, has been a mystery. Until now.

Prevalence of Antibiotic Allergy at a Spinal Cord Injury Center
Infectious diseases are the most common reason for rehospitalization among patients with spinal cord injuries (SCI), regardless of the number of years postinjury.1 The appropriate use and selection of antibiotics for properly diagnosed infectious diseases is especially important for this population. This principle helps to avoid the development of drug-resistant organisms and reduces the risk of recurrent infections, aligning with antibiotic stewardship.
Antibiotics are the most common class of drug allergies in the general population, and penicillin is the most frequently reported allergen (up to 10%).2 Prescription drug–induced anaphylaxis is severe and life threatening with a reported frequency of 1.1%. Penicillin and sulfonamide (46 and 15 per 10,000 patients, respectively) are the most common allergens.3 Although there is a significant difference between an adverse drug reaction (ADR) and true hypersensitivity, once documented in the electronic health record (EHR) as an allergy, this information deters use of the listed drugs.
Genitourinary, skin, and respiratory diseases are the leading causes for rehospitalization in patients with SCI.1 A large proportion of these are infectious in etiology and require antibiotic treatment. In fact, persons with SCI are at high risk for antibiotic overuse and hospital-acquired infection due to chronic bacteriuria, frequent health care exposure, implanted medical devices, and other factors.4 Concurrently, there is a crisis of antibiotic-resistant bacteria proliferation, described asa threat to patient safety and public health.5,6 Its severity is illustrated by the report that 38% of the cultures from patients with spinal cord injury are multidrug resistant gram-negative organisms.7
The SCI center at James A. Haley Veterans’ Hospital (JAHVH) in Tampa, Florida, serves a high concentration of active-duty military members and veterans with SCI. A study that reviews the exact frequency of antibiotic drug allergies listed on the EHR would be a key first step to identify the magnitude of this issue. The results could guide investigation into differentiating true allergies from ADRs, thereby widening the options for potentially life-saving antibiotic treatment.
Methods
We performed a retrospective chart review of patients included in the local SCI registry between October 1, 2015, and September 30, 2017. We collected data on patient demographics (age, sex, race and ethnicity) and a description of patients’ injuries (International Standards for Neurological Classification of Spinal Cord Injury [ISNCSCI] and etiology of injury [traumatic vs atraumatic]). The outcomes included antibiotic allergy and ADRs.
In the EHR, allergies can be listed toward an antibiotic class or a specific antibiotic. An allergy to each specific antibiotic would be recorded separately; however, overlap among antibiotic classes was not duplicated. For example, if a subject has a listed antibiotic allergy to ceftriaxone and cefepime with listed reactions, we would record allergies to each of these antibiotics but would only report a single allergy to the cephalosporin subclass.
Since we did not differentiate hypersensitivity reactions (HSRs) from other ADRs, the reported reactions were grouped by signs and symptoms. There is a variety of terms used to report similar reactions, and best efforts were made to record the data as accurately as possible. Patient-reported history for risk stratification is a tool we used to group these historical reactions into high- vs low-risk for severe reactions. High-risk signs are those listed as anaphylaxis; anaphylactic reactions; angioedema presenting as swelling of mouth, eyes, lips, or tongue; blisters or ulcers involving the lips, mouth, eyes, urethra, vagina, or peeling skin; respiratory changes; shortness of breath; dyspnea; hypotension; or organ involvement (kidneys, lungs, liver).6
Inclusion criteria were all veterans who were diagnosed with tetraplegia or paraplegia and received annual evaluation between October 1, 2015, and September 30, 2017. We chose this period because it was the beginning of a financial year at the JAHVH SCI department using the SCI registry. The SCI annual evaluation is a routine practitioner encounter with the veteran, along with appropriate laboratory testing and imaging to follow up potential chronic health issues specific to patients with SCI. Annual evaluations provide an opportunity to maintain routine health screening and preventive care. Patients who had significant portions of data missing or missing elements of primary outcomes were excluded from analysis. The study was reviewed and approved by the University of South Florida Institutional Review Board (VA IRBNet #1573370-4 on September 9, 2019).
Results
Of 1866 patients reviewed, 207 (11.1%) were excluded due to missing data, resulting in 1659 records that were analyzed. Mean age was 64 years, and male to female ratio was about 10 to 1. Most of the SCI or diseases were classified as incomplete (n = 1249) per ISNCSCI (absence of sensory and motor function in the lowest sacral segments) compared with 373 classified as complete. 
Of the 1659 patients, 494 (29.8%) had a recorded allergy to antibiotics. The most frequently recorded were 217 penicillin (13.1%), 159 sulfa drugs (9.6%), 75 fluoroquinolone (4.5%), 66 cephalosporin (4.0%), and 44 vancomycin (2.7%) allergies. 
Discussion
In this study, we evaluated the frequency and characteristics of antibiotic allergies at a single SCI center to better identify potential areas for quality improvement when recording drug allergies. A study in the general population used self-reported methods to collect such information found about a 15% prevalence of antibiotic allergy, which was lower than the 29.8% prevalence noted in our study.8
Regarding the most common antibiotic allergies, one study reported allergy to penicillin in the EHR in 12.8% of patients at a major US regional health care system, while 13.1% of patients with SCI had documented allergy to penicillin in our study.9 Regarding the other antibiotic classes, the percentage of allergies were higher than those reported in the general population: sulfonamide (9.6% vs 7.4%), fluoroquinolones (4.5% vs 1.3%), and cephalosporins (4.0% vs 1.7%).10 The EHR appears to capture a much higher rate of antibiotic allergies than that in self-reported studies, such as a study of self-reported allergy in the general adult population in Portugal, where only 4.5% of patients reported allergy to any β-lactam medications.10
The prevalence of an antibiotic allergy could be affected by the health care setting and sex distribution. For example, the Zhou and colleagues’ study conducted in the Greater Boston area showed higher reported antibiotic rates than those in a study from a Southern California medical group. The higher proportion of tertiary referral patients in that specific network was suggested to be the cause of the difference.8,9 Our results in the SCI population are more comparable to that in a tertiary setting. This is consistent with the fact that persons with SCI generally have more exposure to antibiotics and consequently a higher reported rate of allergic reactions to antibiotics.
Similarly, the same study in Southern California noted that female patients use more antibiotics than do male patients, thus potentially contributing to higher rates of reported allergy toward all classes of antibiotics.8 Our study did not investigate antibiotic allergy by sex; however, the significantly higher proportion of male sex among the veteran population would have impacted these results.
Limitations
Our study was limited as a single-center retrospective study. However, our center is one of the major SCI specialty hubs, and the results should be somewhat reflective of those in the veterans with SCI population. Veterans under the US Department of Veterans Affairs (VA) medical care have the option to seek care or procedures in non-VA facilities. If allergies to antibiotics occurred outside of the VA system, there is no mechanism to automatically merge with the VA EHR allergy list, unless they are later recorded and added to the VA EHR. Thus, there is potential for underreporting.
Drug anaphylaxis incidence was noted to change over time.4,8,9 For example, a downtrend of reported antibiotic allergy was reported between 1990 and 2013.10 Our study only reflects an overall prevalence of a single cohort, without demonstration of relationship to time.
Lastly, this study did not aim to differentiate HSRs from other ADRs. This is exactly the point of the study, which investigated the frequency of EHR-recorded antibiotic allergies in our SCI population and reflects the issue with indiscriminate recording of ADRs and HSRs under the umbrella of allergy in the EHR. Further diagnosing true allergies should be considered in the SCI population after weighing the risks and benefits of assessment, aligning with the wishes of the veteran, obtaining informed consent, and addressing the cost-effectiveness of specific tests. We suggest that primary care practitioners work closely with allergy specialists to formulate a mechanism to diagnose various antibiotic allergic reactions, including serum tryptase, epicutaneous skin testing, intradermal skin testing, patch testing, delayed intradermal testing, and drug challenge as appropriate. It is also possible that in cases where very mild reactions/adverse effects of antibiotics were recorded in the EHR, the clinicians and veterans may discuss reintroducing the same antibiotics or proceeding with further testing if necessary. In contrast, the 12% of those with a high risk of severe allergic reactions to penicillin in our study would benefit from allergist evaluation and access to epinephrine auto-injectors at all times. Differentiating true allergy is the only clear way to deter unnecessary avoidance of first-line therapies for antibiotic treatment and avoid promotion of antibiotic resistance.
Future studies can analyze antibiotic allergy based on demographics, including sex and age difference, as well as exploring outpatient vs inpatient settings. Aside from prevalence, we hope to demonstrate antibiotic allergy over time, especially after integration of diagnostic allergy testing, to evaluate the impact to EHR-recorded allergies.
Conclusions
Almost 30% of patients with SCI had a recorded allergy to at least 1 antibiotic. The most common allergy was to penicillin, which is similar to what has previously been reported for the general adult US population. However, only 12% of those with a penicillin allergy were considered high risk of true allergic reactions. Consequently, there are opportunities to examine whether approaches to confirm true reactions (such as skin testing) would help to mitigate unnecessary avoidance of certain antibiotic classes due to mild ADRs, rather than a true allergy, in persons with SCI. This would be an important effort to combat both individual safety concerns and the public health crisis of antibiotic resistance. Given the available evidence, it is reasonable for SCI health care practitioners to discuss the potential risks and benefits of allergy testing with patients with SCI; this maintains a patient-centered approach that can ensure judicious use of antibiotics when necessary.

In fact, persons with SCI are at high risk for antibiotic overuse and hospital-acquired infection due to chronic bacteriuria, frequent health care exposure, implanted medical devices, and other factors.4 Concurrently, there is a crisis of antibiotic-resistant bacteria proliferation, described asa threat to patient safety and public health.5,6 Its severity is illustrated by the report that 38% of the cultures from patients with spinal cord injury are multidrug resistant gram-negative organisms.7
The SCI center at James A. Haley Veterans’ Hospital (JAHVH) in Tampa, Florida, serves a high concentration of active-duty military members and veterans with SCI. A study that reviews the exact frequency of antibiotic drug allergies listed on the EHR would be a key first step to identify the magnitude of this issue. The results could guide investigation into differentiating true allergies from ADRs, thereby widening the options for potentially life-saving antibiotic treatment.
Methods
We performed a retrospective chart review of patients included in the local SCI registry between October 1, 2015, and September 30, 2017. We collected data on patient demographics (age, sex, race and ethnicity) and a description of patients’ injuries (International Standards for Neurological Classification of Spinal Cord Injury [ISNCSCI] and etiology of injury [traumatic vs atraumatic]). The outcomes included antibiotic allergy and ADRs.
In the EHR, allergies can be listed toward an antibiotic class or a specific antibiotic. An allergy to each specific antibiotic would be recorded separately; however, overlap among antibiotic classes was not duplicated. For example, if a subject has a listed antibiotic allergy to ceftriaxone and cefepime with listed reactions, we would record allergies to each of these antibiotics but would only report a single allergy to the cephalosporin subclass.
Since we did not differentiate hypersensitivity reactions (HSRs) from other ADRs, the reported reactions were grouped by signs and symptoms. There is a variety of terms used to report similar reactions, and best efforts were made to record the data as accurately as possible. Patient-reported history for risk stratification is a tool we used to group these historical reactions into high- vs low-risk for severe reactions. High-risk signs are those listed as anaphylaxis; anaphylactic reactions; angioedema presenting as swelling of mouth, eyes, lips, or tongue; blisters or ulcers involving the lips, mouth, eyes, urethra, vagina, or peeling skin; respiratory changes; shortness of breath; dyspnea; hypotension; or organ involvement (kidneys, lungs, liver).6
Inclusion criteria were all veterans who were diagnosed with tetraplegia or paraplegia and received annual evaluation between October 1, 2015, and September 30, 2017. We chose this period because it was the beginning of a financial year at the JAHVH SCI department using the SCI registry. The SCI annual evaluation is a routine practitioner encounter with the veteran, along with appropriate laboratory testing and imaging to follow up potential chronic health issues specific to patients with SCI. Annual evaluations provide an opportunity to maintain routine health screening and preventive care. Patients who had significant portions of data missing or missing elements of primary outcomes were excluded from analysis. The study was reviewed and approved by the University of South Florida Institutional Review Board (VA IRBNet #1573370-4 on September 9, 2019).
Results
Of 1866 patients reviewed, 207 (11.1%) were excluded due to missing data, resulting in 1659 records that were analyzed. Mean age was 64 years, and male to female ratio was about 10 to 1. Most of the SCI or diseases were classified as incomplete (n = 1249) per ISNCSCI (absence of sensory and motor function in the lowest sacral segments) compared with 373 classified as complete.
Of the 1659 patients, 494 (29.8%) had a recorded allergy to antibiotics. The most frequently recorded were 217 penicillin (13.1%), 159 sulfa drugs (9.6%), 75 fluoroquinolone (4.5%), 66 cephalosporin (4.0%), and 44 vancomycin (2.7%) allergies.
Discussion
In this study, we evaluated the frequency and characteristics of antibiotic allergies at a single SCI center to better identify potential areas for quality improvement when recording drug allergies. A study in the general population used self-reported methods to collect such information found about a 15% prevalence of antibiotic allergy, which was lower than the 29.8% prevalence noted in our study.8
Regarding the most common antibiotic allergies, one study reported allergy to penicillin in the EHR in 12.8% of patients at a major US regional health care system, while 13.1% of patients with SCI had documented allergy to penicillin in our study.9 Regarding the other antibiotic classes, the percentage of allergies were higher than those reported in the general population: sulfonamide (9.6% vs 7.4%), fluoroquinolones (4.5% vs 1.3%), and cephalosporins (4.0% vs 1.7%).10 The EHR appears to capture a much higher rate of antibiotic allergies than that in self-reported studies, such as a study of self-reported allergy in the general adult population in Portugal, where only 4.5% of patients reported allergy to any β-lactam medications.10
The prevalence of an antibiotic allergy could be affected by the health care setting and sex distribution. For example, the Zhou and colleagues’ study conducted in the Greater Boston area showed higher reported antibiotic rates than those in a study from a Southern California medical group. The higher proportion of tertiary referral patients in that specific network was suggested to be the cause of the difference.8,9 Our results in the SCI population are more comparable to that in a tertiary setting. This is consistent with the fact that persons with SCI generally have more exposure to antibiotics and consequently a higher reported rate of allergic reactions to antibiotics.
Similarly, the same study in Southern California noted that female patients use more antibiotics than do male patients, thus potentially contributing to higher rates of reported allergy toward all classes of antibiotics.8 Our study did not investigate antibiotic allergy by sex; however, the significantly higher proportion of male sex among the veteran population would have impacted these results.
Limitations
Our study was limited as a single-center retrospective study. However, our center is one of the major SCI specialty hubs, and the results should be somewhat reflective of those in the veterans with SCI population. Veterans under the US Department of Veterans Affairs (VA) medical care have the option to seek care or procedures in non-VA facilities. If allergies to antibiotics occurred outside of the VA system, there is no mechanism to automatically merge with the VA EHR allergy list, unless they are later recorded and added to the VA EHR. Thus, there is potential for underreporting.
Drug anaphylaxis incidence was noted to change over time.4,8,9 For example, a downtrend of reported antibiotic allergy was reported between 1990 and 2013.10 Our study only reflects an overall prevalence of a single cohort, without demonstration of relationship to time.
Lastly, this study did not aim to differentiate HSRs from other ADRs. This is exactly the point of the study, which investigated the frequency of EHR-recorded antibiotic allergies in our SCI population and reflects the issue with indiscriminate recording of ADRs and HSRs under the umbrella of allergy in the EHR. Further diagnosing true allergies should be considered in the SCI population after weighing the risks and benefits of assessment, aligning with the wishes of the veteran, obtaining informed consent, and addressing the cost-effectiveness of specific tests. We suggest that primary care practitioners work closely with allergy specialists to formulate a mechanism to diagnose various antibiotic allergic reactions, including serum tryptase, epicutaneous skin testing, intradermal skin testing, patch testing, delayed intradermal testing, and drug challenge as appropriate. It is also possible that in cases where very mild reactions/adverse effects of antibiotics were recorded in the EHR, the clinicians and veterans may discuss reintroducing the same antibiotics or proceeding with further testing if necessary. In contrast, the 12% of those with a high risk of severe allergic reactions to penicillin in our study would benefit from allergist evaluation and access to epinephrine auto-injectors at all times. Differentiating true allergy is the only clear way to deter unnecessary avoidance of first-line therapies for antibiotic treatment and avoid promotion of antibiotic resistance.
Future studies can analyze antibiotic allergy based on demographics, including sex and age difference, as well as exploring outpatient vs inpatient settings. Aside from prevalence, we hope to demonstrate antibiotic allergy over time, especially after integration of diagnostic allergy testing, to evaluate the impact to EHR-recorded allergies.
Conclusions
Almost 30% of patients with SCI had a recorded allergy to at least 1 antibiotic. The most common allergy was to penicillin, which is similar to what has previously been reported for the general adult US population. However, only 12% of those with a penicillin allergy were considered high risk of true allergic reactions. Consequently, there are opportunities to examine whether approaches to confirm true reactions (such as skin testing) would help to mitigate unnecessary avoidance of certain antibiotic classes due to mild ADRs, rather than a true allergy, in persons with SCI. This would be an important effort to combat both individual safety concerns and the public health crisis of antibiotic resistance. Given the available evidence, it is reasonable for SCI health care practitioners to discuss the potential risks and benefits of allergy testing with patients with SCI; this maintains a patient-centered approach that can ensure judicious use of antibiotics when necessary.

Clinic responsible for misdiagnosing newborn’s meningitis, must pay millions
according to a report in the Star Tribune, among other news outlets.
The story of the jury verdict begins in 2013, when the boy, Johnny Galligan, was just 8 days old.
Alarmed by the newborn’s crying, lack of appetite, and fever, his parents, Alina and Steve Galligan, brought him to Essentia-Health-Ashland Clinic, located in Memorial Medical Center, Ashland, Wisc. There, the baby was seen by Andrew D. Snider, MD, a family physician. Dr. Snider noted the baby’s extreme fussiness and irritability and was concerned that he was being overfed. Without ordering additional tests, the family physician sent the baby home but arranged for the Galligans to be visited by a county nurse the following day.
Her visit raised concerns, as court documents make clear. She contacted Dr. Snider’s office and explained that the baby needed to be seen immediately. After writing a script for reflux and constipation, Dr. Snider arranged for the baby to be taken to his office later that day.
Events proceeded rapidly from this point.
Following an x-ray, Johnny appeared lethargic and in respiratory distress. He was then taken down the hall to Memorial’s emergency department, where doctors suspected a critical bowel obstruction. Arrangements were made for him to be transported by helicopter to Essentia Health, Duluth, Minn. There, doctors saw that Johnny was acidotic and in respiratory failure. Once again, he was rerouted, this time to Children’s Hospital, Minneapolis, where physicians finally arrived at a definitive diagnosis: meningitis.
In 2020, the Galligans filed a medical malpractice claim against several parties, including Dr. Snider, Duluth Clinic (doing business as Essentia Health and Essentia Health–Ashland Clinic), and Memorial Hospital. In their suit, Johnny’s parents alleged that the collective failure to diagnose their son’s severe infection led directly to his permanent brain damage.
But a Bayfield County, Wisconsin, jury didn’t quite see things that way. After deliberating, it dismissed the claim against Dr. Snider and the other named defendants and found the staff of Duluth Clinic to be solely responsible for injuries to Johnny Galligan.
Duluth must pay $19 million to the Galligan family, of which the largest amount ($7,500,00) is to be directed to Johnny’s “future medical expenses and care needs.”
These expenses and costs are likely to be significant. Currently, at 10 years of age, Johnny can’t walk and is confined to a wheelchair. He has serious neurologic problems and is almost completely deaf and blind.
“He’s doing fairly well, which I attribute to his family providing care for him,” says the attorney who represented the Galligans. “They care for him 24/7. They take him swimming and on four-wheeler rides. He’s not bedridden. He has the best possible quality of life he could have, in my opinion.”
In a statement following the verdict, Essentia Health said that, while it felt “compassion for the family,” it stood by the care it had provided in 2013: “We are exploring our options regarding next steps and remain committed to delivering high-quality care to the patients and communities we are privileged to serve.”
ED physician found not liable for embolism, jury finds
A Missouri doctor accused of incorrectly treating a woman’s embolism has been found not liable for her death, reports a story in Missouri Lawyers Media.
The woman went to her local hospital’s ED complaining of pain and swelling in her leg. At the ED, an emergency physician examined her and discovered an extensive, visible thrombosis. No other symptoms were noted.
In the past, such a finding would have prompted immediate hospital admission. But the standard of care has evolved. Now, many doctors first prescribe enoxaparin sodium (Lovenox), an anticoagulant used to treat deep-vein thrombosis. This was the option chosen by the Missouri emergency physician to treat his patient. After administering a first dose of the drug, he wrote a script for additional doses; consulted with his patient’s primary care physician; and arranged for the patient to be seen by him, the ED physician, the following day.
At the drugstore, though, the woman became ill, and an emergency medical services crew was alerted. Despite its quick response, the woman died en route to the hospital. No autopsy was later performed, and it was generally presumed that she had died of a pulmonary embolism.
Following the woman’s death, her family sued the emergency physician, alleging that his failure to admit the woman to the hospital most likely delayed treatment that could have saved her life.
The defense pushed back, arguing that the ED physician had followed the standard of care. “Even if she [had] come into the ER with full-blown [pulmonary embolism],” says the attorney representing the emergency physician, “the first thing you do is give Lovenox. It is just one of those rare circumstances where you can do everything right, but the patient can still die.”
The trial jury agreed. After deliberating for more than an hour, it found that the emergency physician was not responsible for the patient’s death.
At press time, there was no word on whether the plaintiffs planned to appeal.
