Rotavirus vaccination is not a risk factor for type 1 diabetes
published in
Previous findings from a number of studies have indicated a possible association between rotavirus and type 1 diabetes, according to Jason M. Glanz, PhD, and colleagues. “Epidemiologic data suggest an association between gastrointestinal infection and incidence of type 1 diabetes in children followed from birth to age 10 years. Given these findings, it is biologically plausible that live, attenuated rotavirus vaccine could either increase or decrease the risk for type 1 diabetes in early childhood,” they wrote.
To examine the association between rotavirus vaccination and the incidence of type 1 diabetes in a cohort of U.S. children, Dr. Glanz, a senior investigator at the Kaiser Permanente Colorado Institute for Health Research in Aurora, and colleagues retrospectively analyzed data from seven health care organizations that participate in the Vaccine Safety Datalink.
The researchers identified children born between 2006 and 2014 who had continuous enrollment from age 6 weeks to 2 years. They excluded children with a medical contraindication to vaccination or fewer than two well-child visits by age 12 months. They followed children until a type 1 diabetes diagnosis, disenrollment, or Dec. 31, 2017. The researchers adjusted for sex, birth year, mother’s age, birth weight, gestational age, and race or ethnicity.
The cohort included 386,937 children who were followed up a median of 5.4 years for a total person-time follow-up of 2,253,879 years. In all, 386,937 children (93.1%) were fully exposed to rotavirus vaccination; 15,765 (4.1%) were partially exposed to rotavirus vaccination, meaning that they received some, but not all, vaccine doses; and 11,003 (2.8%) were unexposed to rotavirus vaccination but had received all other recommended vaccines.
There were 464 cases of type 1 diabetes in the cohort, with an incidence rate of 20 cases per 100,000 person-years in the fully exposed group, 31.2 cases per 100,000 person-years in the partially exposed group, and 22.4 cases per 100,000 person-years in the unexposed group.
The incidence of type 1 diabetes was not significantly different across the rotavirus vaccine–exposure groups. The researchers reported that, compared with children unexposed to rotavirus vaccination, the adjusted hazard ratio for children fully exposed to rotavirus vaccination was 1.03 (95% confidence interval, 0.62-1.72), and for those partially exposed to the vaccination, it was 1.50 (95% CI, 0.81-2.77).
“Since licensure, rotavirus vaccination has been associated with a reduction in morbidity and mortality due to rotavirus infection in the United States and worldwide. ... Although rotavirus vaccination may not prevent type 1 diabetes, these results should provide additional reassurance to the public that rotavirus vaccination can be safely administered to infants,” they wrote.
The limited follow-up duration and relatively small proportion of patients unexposed to rotavirus vaccination are limitations of the study, the authors noted.
The Centers for Disease Control and Prevention funded the study. Several authors reported having received grants from the CDC. One author received grants from the National Institute of Diabetes and Digestive and Kidney Diseases, and another from pharmaceutical companies not involved in the study.

More inclusive assessment better predicts cognitive impairment in very preterm children
rather than just severe impairment, in ongoing monitoring, according to a study published in
Carmina Erdei, MD, of Brigham and Women’s Hospital and the department of pediatrics at Harvard Medical school, both in Boston, and colleagues prospectively studied 103 children born VPT (32 weeks’ or less gestation) and 109 children born term. Exclusion criteria included congenital abnormalities and having non–English-speaking parents.
The investigators assessed the children’s cognitive abilities and neurodevelopment with age-appropriate measures at various ages: Bayley Scales of Infant Development (2nd ed.) at age 2 years, Wechsler Preschool and Primary Scale of Intelligence at age 4 and 6 years, and Wechsler Intelligence Scale for Children (4th ed.) at age 9 and 12 years.
When only severe cognitive impairment at ages 2, 4, and 6 years was used as the criterion for ongoing monitoring, between 18% and 44% of severely impaired children at 12 years were missed – and would not have received continued monitoring and support. However, when any cognitive impairment at the younger ages was the criterion for continued monitoring, 100% of cases of severe impairment at age 12 years were correctly predicted.
The authors suggest that adoption of this more inclusive approach may be warranted, given the long-term ramifications of even mild cognitive impairment.
Positive predictive value (66%), negative predictive value (89%), and specificity (73%) intersected in assessments performed at age 6 years, such that they had the best predictive ability for any cognitive impairment at age 12 years.
“Our findings highlight the potential benefit of monitoring children at high risk with early delay until elementary school,” the authors wrote. “We acknowledge that this would result in a higher number of referrals and potentially increased short-term costs. Developmental follow-up is costly, yet early developmental services are valuable and positively impact preterm children’s cognitive and preacademic skills.”
The investigators also assessed family-social risks, such as socioeconomic status and maternal education, and found that children born VPT were more than twice as likely to be raised in families with more risks than were those born term (33% vs. 13%, respectively).
Limitations of the study include the high false-positive rate (34%) seen with the assessments at age 6 years, but the authors suggested that could be mitigated with risk stratification.
The study was funded by the Neurological Foundation, Lottery Grants Board, Canterbury Medical Research Foundation, and Health Research Council of New Zealand. The authors reported having no relevant financial relationships or conflicts of interest.

Breaking bacterial communication may heal EB wounds
LONDON – Disrupting how microorganisms communicate with each other could be a way to overcome antibiotic resistance and to help heal chronic wounds in patients with epidermolysis bullosa (EB), according to presenters at the EB World Congress, organized by the Dystrophic Epidermolysis Bullosa Association (DEBRA).
The majority of chronic wounds in patients with EB are colonized with microorganisms, with a predominance of Staphylococcus species, said Erik Gerner, an industrial PhD student at Mölnlycke Health Care in Gothenburg, Sweden, and Gothenburg University.
Because of the growing problem of antibiotic resistance, alternative treatments are needed, and one possible alternative for treating infected wounds could be interfering with quorum sensing, the cell-to-cell communication used by bacteria, he said. He is hoping to explore this possibility as a novel treatment strategy for infected wounds.
“Quorum sensing is defined as the ability to detect and respond to population density,” Mr. Gerner said, noting that, when there is a sufficient density of bacteria, “they start to communicate with each other.” This enables them to act as a community and perform actions that they could not do as individual cells. Such actions include forming biofilms, which helps protect bacteria from their environment, such as the immune system. Other actions include collectively switching on the production of virulence factors and becoming resistant to treatments.
“Bacteria use quorum sensing to act collectively,” Mr. Gerner said. “If we could shut down this quorum sensing system, it would be very beneficial … and increase the chances to heal the wound.”
The quorum sensing system is based on the production of signaling molecules called AHL (N-acyl homoserine lactones), which are constantly produced at a low rate. This isn’t a problem until the level of bacteria increases and the level of quorum sensing breaches a threshold, he explained.
There are several benefits of inhibiting bacterial communication through disrupting quorum sensing, namely, “a low risk of resistance,” Mr. Gerner said. There is also potentially less toxin production by bacteria, and this could help the immune system in killing the invading bacteria.
One approach to disrupting quorum testing that Mr. Gerner has been investigating is the use of sodium salicylate (NaSa). So far, preclinical work shows that NaSa can reduce toxin production but not the growth rate of bacteria. The advantage of using NaSa is that it is nontoxic to human dermal fibroblasts, with similar results seen in human keratinocytes and immune cells. His work to date has shown that NaSa reduced activity of NF-kB (a proinflammatory signaling pathway) in differentiated and lipopolysaccharide-stimulated monocytes; NF-kB activated production of proinflammatory cytokines (such as interleukin-1 beta and IL-6) are elevated in EB wounds. “My studies support the bodies of evidence that bacteria use quorum sensing to coordinate … and to produce a large number of toxic factors,” Mr. Gerner concluded. Future studies will look at the potential of NaSa to disrupt this activity.
Skin microbiome of EB wounds
Liat Samuelov, MD, of the department of molecular dermatology at Tel Aviv (Israel) Sourasky Medical Center, presented data on skin microbiome characteristics in eight patients with recessive dystrophic EB (RDEB). This showed that there was reduced bacterial diversity in wounds, and a “progressive development of dysbiosis across different stages of DEB wound formation.”
The skin microbiome has been implicated in several skin diseases, Dr. Samuelov and associates observed in a poster presentation. That includes the autoimmune blistering disease bullous pemphigoid (Exp Dermatol. 2017 Dec;26[12]:1221-7). “Colonization of DEB chronic wounds may lead to systemic infections, result in delayed healing, and possibly be involved in the development of squamous cell carcinoma,” they noted in the poster, “thus accurate delineation of the dysbiotic profile … may point to corrective measures of great therapeutic potential.”
The aim was to see what microorganisms were present in the chronic wounds of the patients. To be included in the study, patients must not have had any antibiotic treatment – oral or topical – in the past 6 months. Samples were taken from an untreated wound, around the wound, and from uninvolved skin, which were compared with samples taken from similar areas in age-matched controls.
Reduced bacterial diversity was observed in RDEB wounds, compared with uninvolved or perilesional areas and the skin of control subjects, Dr. Samuelov said in an oral presentation of the study results. There was increased abundance of Staphylococcus epidermidis and decreased Cutibacterium acnes, which she noted was in contrast to other studies where S. aureus was the most common colonizer in RDEB wounds.
Bacterial composition in each group was calculated using the beta-diversity score, while control samples showed similar microbial composition, the DEB samples had no microbial similarities among different samples. These data “suggest the need to ascertain the potential therapeutic benefit of interventions aimed at restoring normal microbiome composition in DEB,” Dr. Samuelov concluded.
Wound colonization and squamous cell carcinoma
Other research on wound microbiology was presented by Laura E. Levin, MD, a dermatologist at New York–Presbyterian, and associates. “Given the potential role of bacteria-induced inflammation in the development of wound-associated SCC [squamous cell carcinoma] in a subset of patients, we sought to improve our understanding of what microbes colonize and infect the wounds of patients with epidermolysis bullosa,” they explained in their poster.
The researchers, from New York–Presbyterian Morgan Stanley Children’s Hospital and Columbia University Irvine Medical Center, New York, presented data from a retrospective analysis of 739 wound cultures taken between 2001 and 2017 from 158 patients enrolled in the Epidermolysis Bullosa Clinical Characterization and Outcomes Database. In the analysis, just under 70% of patients had DEB, of which 90% were of the RDEB subtype; 13% had EB simplex, 14% had junctional EB, and 3% had an unknown EB subtype.
At least one organism grew in 87% of cultures, with the most common microorganism isolated being Staphylococcus aureus (84% of cultures). Other commonly isolated microbes were Pseudomonas aeruginosa in 35% of cultures, Streptococcus group A in 34% of cultures (of which 22% were Streptococcus pyogenes), Corynebacterium species in 31% of cultures, and Proteus species in 18% of cultures.
“Improved understanding of what microbes are colonizing the wounds of our patients may help improve antibiotic stewardship,” the researchers stated.
Looking at the antibiotic susceptibilities, Dr. Levin and associates found that 68% of 115 cultures were sensitive to methicillin and 60% of 15 cultures were sensitive to mupirocin. “Resistance to many systemic and topical antibiotic agents in EB patients supports surveillance cultures with routine testing for mupirocin susceptibility,” they suggested.
A total of 23 patients developed SCC of whom 10 had cultures that grew S. aureus (90%) and P. aeruginosa (50%), and Proteus species (20%). Among the patients who did not develop SCC, the respective cultures positive for each of those microorganisms were 83%, 34%, and 11%. Perhaps “gram-negative and flagellated organisms may be more common in wounds of patients at risk for SCC,” they observed, adding that further studies were needed to determine if “wound microbiome interventions inhibit the risk of development of SCC and improve outcomes.”
Mr. Gerner’s research is supported by Mölnlycke Health Care. Dr. Samuelov had no disclosures. The work by Dr. Levin and associates is supported by the Pediatric Dermatology Research Alliance, EB Research Partnership, and the Epidermolysis Bullosa Medical Research Foundation.

“Quorum sensing is defined as the ability to detect and respond to population density,” Mr. Gerner said, noting that, when there is a sufficient density of bacteria, “they start to communicate with each other.” This enables them to act as a community and perform actions that they could not do as individual cells. Such actions include forming biofilms, which helps protect bacteria from their environment, such as the immune system. Other actions include collectively switching on the production of virulence factors and becoming resistant to treatments.
“Bacteria use quorum sensing to act collectively,” Mr. Gerner said. “If we could shut down this quorum sensing system, it would be very beneficial … and increase the chances to heal the wound.”
The quorum sensing system is based on the production of signaling molecules called AHL (N-acyl homoserine lactones), which are constantly produced at a low rate. This isn’t a problem until the level of bacteria increases and the level of quorum sensing breaches a threshold, he explained.
There are several benefits of inhibiting bacterial communication through disrupting quorum sensing, namely, “a low risk of resistance,” Mr. Gerner said. There is also potentially less toxin production by bacteria, and this could help the immune system in killing the invading bacteria.
One approach to disrupting quorum testing that Mr. Gerner has been investigating is the use of sodium salicylate (NaSa). So far, preclinical work shows that NaSa can reduce toxin production but not the growth rate of bacteria. The advantage of using NaSa is that it is nontoxic to human dermal fibroblasts, with similar results seen in human keratinocytes and immune cells. His work to date has shown that NaSa reduced activity of NF-kB (a proinflammatory signaling pathway) in differentiated and lipopolysaccharide-stimulated monocytes; NF-kB activated production of proinflammatory cytokines (such as interleukin-1 beta and IL-6) are elevated in EB wounds. “My studies support the bodies of evidence that bacteria use quorum sensing to coordinate … and to produce a large number of toxic factors,” Mr. Gerner concluded. Future studies will look at the potential of NaSa to disrupt this activity.
Skin microbiome of EB wounds
Liat Samuelov, MD, of the department of molecular dermatology at Tel Aviv (Israel) Sourasky Medical Center, presented data on skin microbiome characteristics in eight patients with recessive dystrophic EB (RDEB). This showed that there was reduced bacterial diversity in wounds, and a “progressive development of dysbiosis across different stages of DEB wound formation.”
The skin microbiome has been implicated in several skin diseases, Dr. Samuelov and associates observed in a poster presentation. That includes the autoimmune blistering disease bullous pemphigoid (Exp Dermatol. 2017 Dec;26[12]:1221-7). “Colonization of DEB chronic wounds may lead to systemic infections, result in delayed healing, and possibly be involved in the development of squamous cell carcinoma,” they noted in the poster, “thus accurate delineation of the dysbiotic profile … may point to corrective measures of great therapeutic potential.”
The aim was to see what microorganisms were present in the chronic wounds of the patients. To be included in the study, patients must not have had any antibiotic treatment – oral or topical – in the past 6 months. Samples were taken from an untreated wound, around the wound, and from uninvolved skin, which were compared with samples taken from similar areas in age-matched controls.
Reduced bacterial diversity was observed in RDEB wounds, compared with uninvolved or perilesional areas and the skin of control subjects, Dr. Samuelov said in an oral presentation of the study results. There was increased abundance of Staphylococcus epidermidis and decreased Cutibacterium acnes, which she noted was in contrast to other studies where S. aureus was the most common colonizer in RDEB wounds.
Bacterial composition in each group was calculated using the beta-diversity score, while control samples showed similar microbial composition, the DEB samples had no microbial similarities among different samples. These data “suggest the need to ascertain the potential therapeutic benefit of interventions aimed at restoring normal microbiome composition in DEB,” Dr. Samuelov concluded.
Wound colonization and squamous cell carcinoma
Other research on wound microbiology was presented by Laura E. Levin, MD, a dermatologist at New York–Presbyterian, and associates. “Given the potential role of bacteria-induced inflammation in the development of wound-associated SCC [squamous cell carcinoma] in a subset of patients, we sought to improve our understanding of what microbes colonize and infect the wounds of patients with epidermolysis bullosa,” they explained in their poster.
The researchers, from New York–Presbyterian Morgan Stanley Children’s Hospital and Columbia University Irvine Medical Center, New York, presented data from a retrospective analysis of 739 wound cultures taken between 2001 and 2017 from 158 patients enrolled in the Epidermolysis Bullosa Clinical Characterization and Outcomes Database. In the analysis, just under 70% of patients had DEB, of which 90% were of the RDEB subtype; 13% had EB simplex, 14% had junctional EB, and 3% had an unknown EB subtype.
At least one organism grew in 87% of cultures, with the most common microorganism isolated being Staphylococcus aureus (84% of cultures). Other commonly isolated microbes were Pseudomonas aeruginosa in 35% of cultures, Streptococcus group A in 34% of cultures (of which 22% were Streptococcus pyogenes), Corynebacterium species in 31% of cultures, and Proteus species in 18% of cultures.
“Improved understanding of what microbes are colonizing the wounds of our patients may help improve antibiotic stewardship,” the researchers stated.
Looking at the antibiotic susceptibilities, Dr. Levin and associates found that 68% of 115 cultures were sensitive to methicillin and 60% of 15 cultures were sensitive to mupirocin. “Resistance to many systemic and topical antibiotic agents in EB patients supports surveillance cultures with routine testing for mupirocin susceptibility,” they suggested.
A total of 23 patients developed SCC of whom 10 had cultures that grew S. aureus (90%) and P. aeruginosa (50%), and Proteus species (20%). Among the patients who did not develop SCC, the respective cultures positive for each of those microorganisms were 83%, 34%, and 11%. Perhaps “gram-negative and flagellated organisms may be more common in wounds of patients at risk for SCC,” they observed, adding that further studies were needed to determine if “wound microbiome interventions inhibit the risk of development of SCC and improve outcomes.”
Mr. Gerner’s research is supported by Mölnlycke Health Care. Dr. Samuelov had no disclosures. The work by Dr. Levin and associates is supported by the Pediatric Dermatology Research Alliance, EB Research Partnership, and the Epidermolysis Bullosa Medical Research Foundation.
REPORTING FROM EB 2020
Flu activity declines again but remains high
Outpatient visits to health care providers for influenza-like illness dropped from 5.5% the previous week to 5.3% of all visits for the week ending Feb. 29, the Centers for Disease Control and Prevention said on March 6.
The national baseline rate of 2.4% was first reached during the week of Nov. 9, 2019 – marking the start of flu season – and has remained at or above that level for 17 consecutive weeks. Last year’s season, which also was the longest in a decade, lasted 21 consecutive weeks but started 2 weeks later than the current season and had a lower outpatient-visit rate (4.5%) for the last week of February, CDC data show.
This season’s earlier start could mean that even a somewhat steep decline in visits to below the baseline rate – marking the end of the season – might take 5 or 6 weeks and would make 2019-2020 even longer than 2018-2019.
The activity situation on the state level reflects the small national decline. For the week ending Feb. 29, there were 33 states at level 10 on the CDC’s 1-10 activity scale, compared with 37 the week before, and a total of 40 in the “high” range of 8-10, compared with 43 the week before, the CDC’s influenza division reported.
The other main measure of influenza activity, percentage of respiratory specimens testing positive, also declined for the third week in a row and is now at 24.3% after reaching a high of 30.3% during the week of Feb. 2-8, the influenza division said.
The overall cumulative hospitalization rate continues to remain at a fairly typical 57.9 per 100,000 population, but rates for school-aged children (84.9 per 100,000) and young adults (31.2 per 100,000) are among the highest ever recorded at this point in the season. Mortality among children – now at 136 for 2019-2020 – is higher than for any season since reporting began in 2004, with the exception of the 2009 pandemic, the CDC said.

Arsenic levels in infant rice cereal are down
according to test results released by the Food and Drug Administration.
In April 2016, the FDA issued draft guidance calling for manufacturers of the product to reduce the level of arsenic in their cereals by establishing an action level of arsenic of 100 mcg/kg or 100 parts per billion.
Seventy-six percent of samples of infant rice cereal tested in 2018 had levels of arsenic at or below 100 parts per billion versus 47% of samples tested in 2014, according to a statement from the FDA. In 2011-2013, an even lower percentage of samples tested contained amounts of inorganic arsenic at or below the FDA’s current action level for this element, whose consumption has been associated with cancer, skin lesions, cardiovascular diseases, and diabetes.
The 2018 data is based on the testing of 149 samples of infant white and brown rice cereal samples.
“Results from our tests show that manufacturers have made significant progress in ensuring lower levels of inorganic arsenic in infant rice cereal,” Susan Mayne, PhD, director of the Center for Food Safety and Applied Nutrition, said in the FDA statement.
“Both white rice and brown rice cereals showed improvement in meeting the FDA’s 100 ppb proposed action level, but the improvement was greatest for white rice cereals, which tend to have lower levels of inorganic arsenic overall,” according to the statement.

There’s hope: Curbing food wastage at the school cafeteria
It’s hard to find good news these days, but I thought I had stumbled on a nice feel-good story in the Portland Press Herald. It turns out a group of students at the King Middle School in Portland, Maine, has formed a team of “compost guardians,” who by coaxing their fellow students into sorting their uneaten lunch food into five reusable or recyclable categories have reduced the cafeteria’s daily waste production from 12 40-gallon trash bags to 2. (“Each year, Maine’s K-12 schools waste about 7 million pounds of food,” by Rachel Ohm, Portland Press Herald, Feb. 2, 2020). That seems like a heroic accomplishment and good news by any standard.
However, as I read on in the newspaper article it became clear that these students’ efforts represent a tiny speck of light in the middle of a very dark tunnel. In developing their system, the students learned that 34% of the food was not being consumed, which is part of the 30%-40% of food wasted across the country. In Maine, this represents about 7 million pounds of food wasted annually. Not surprisingly, the students found that 60% of the fruit and 28% of the vegetables go uneaten.
But current federal guidelines dictate that students must take a vegetable and a fruit on their trays. While well-intentioned, this is a mandate destined to generate waste.
King Middle School and many other schools around the country offer a program that is not in the federal guidelines: a “share table” where students can place unwanted (but safe to eat) food, and from which other students may serve themselves freely. On the surface, this may seem like a good idea because it legitimizes what children have been doing for years on their own. This shared food should consist of “healthy choices” because it is cafeteria fare dictated by the United States Department of Agriculture. But you know as well as I do that a child can become obese overeating a diet that in moderate amounts would be considered healthy. I suspect that many, if not most, students taking food from the share table don’t need any extra calories.
The USDA recently announced that it will be rolling out reforms for school and summer meal programs (USDA Release # USDA 0129.20). One of the goals of these reforms is to reduce food wastage by giving schools more flexibility in creating menus and offering more à la carte options. In the wake this rollout, there has been some concern voiced that schools will begin to offer less nutritional options. Unfortunately, this concern may be true in some districts, but it is pretty clear that the current guidelines are a significant contributor to food wastage without offering much of an upside. It may be time to lessen the record-keeping burden on local food services, and allow them some leeway in creating more appealing options while taking advantage of local food sources.
With or without the new guidelines, we are asking public schools to cater to multiple cohorts of students whose parents have put them on the bus in the morning as mismanaged picky eaters.
What would have worked at home could work at school. That strategy is to offer a child a balanced diet presented in an appealing manner in a pleasant setting. Also it is not allowing any sweetened beverages or milk in excess. Children may grumble temporarily but if the strategy is applied consistently, they will take it from there. That doesn’t mean that the children have to put the food on their trays if they don’t want it. But they shouldn’t be offered a second run through the cafeteria line or a chance to pick from the share table. Sadly, the success of this strategy relies on two shaky premises: That parents will begin to apply it at home and that school lunch programs will offer only healthy choices.
The bottom line is that schools can’t be expected to cure picky eaters who were enabled at home. On the other hand, it is not unreasonable to ask schools to play a role in curbing the national scourge of food wastage.

Gender pronouns in EMR preferred by many gender nonconforming teens
Most transgender and gender nonconforming youth would like their preferred name and pronouns be recorded throughout their EMRs, but very few are ever asked for that identity information outside of gender specialty clinic settings, according to a recent research letter in JAMA Pediatrics.
The findings are not surprising, said Cora Breuner, MD, a professor of pediatrics in adolescent medicine at Seattle Children’s Hospital in Washington, because “we know that use of gender-affirming language when accessing health care is extremely important to transgender youth.”
“Use of gender-affirming language in the health care system is associated with improved mental health outcomes in this population,” Dr Breuner said in an interview.
But the authors of the study noted that EMRs often lack the functions needed to provide gender-affirming care.
“To better support this vulnerable group of youths, health systems and EMRs should allow for EMR-wide name and pronoun documentation, even when a patient has not legally changed their name,” Gina M. Sequeira, MD, of UPMC Children’s Hospital of Pittsburgh and associates wrote.
Although many providers have begun routinely asking patients for both their gender identity and their sex assigned at birth, these questions leave out a patient’s preferred name and pronouns – crucial components of respectful and affirming care, the authors explained.
At a specialty gender clinic, the authors surveyed 204 transgender youths, aged 12-26 years, regarding how their name and pronouns are recorded in their EMR files. Just over half the respondents were under age 18 years (56%), and most were white (86%). Most were transmasculine (59%), with 21% transfeminine and 20% nonbinary.
Most respondents (69%) went by a name other than their legal one, yet only 9% said they were frequently or always asked in clinical settings outside specialty gender centers whether they wanted their preferred name and pronouns noted in the EMR.
A majority (79%), however, said they wanted their name and pronouns noted throughout their EMR. The youths’ preferences varied according to their gender identity and how many people were aware of their gender identity, but not by age, race/ethnicity, or perceived amount of parental support.
Only two-thirds (67%) of 42 transfeminine patients wished their EMR to include their preferred name, compared with most (85%) of 121 transmasculine patients and nearly all (92%) of 37 nonbinary respondents (P = .007). Pronouns preferences were similar: All but one nonbinary respondent wanted their pronouns in the EMR, compared with 84% of transmasculine and 64% of transfeminine respondents (P=.0003).
“It may be that transfeminine patients have more pressure to ‘stay’ their assigned gender,” Dr Breuner said regarding these findings. “ ‘Outness’ may be challenging, and thus they remain in their traditional gender norms, but further research on this theory is warranted.”
Among those who were “out to everyone,” most (88%) wanted their preferred name and pronouns recorded in the EMR, and the proportion was similar for those “out to most.” But only 65% of those “out to few or no one” preferred their name and pronouns be noted in the EMR, a similar proportion for those “out to some.”
Of 7 youths who did not wish to include their name and pronouns throughout their EMR, all but one said they didn’t think it was necessary because they believed they already “passed” well enough as their gender. Just one person said they did not want name and pronouns recorded for confidentiality reasons.
However, confidentiality is still an important consideration particularly for minors, the authors and Dr. Breuner pointed out.
“It is essential to discuss confidentiality with the youth as parents may have access to the medical records younger than 18 years of age,” Dr. Breuner said.
The authors noted the study’s limitation in using a convenience sample but they and Dr. Breuner said that the findings still demonstrate transgender youths’ desire for EMRs to include their name and pronouns.
The research was funded by grants from the National Institutes of Health. The authors had no industry disclosures.

Although many providers have begun routinely asking patients for both their gender identity and their sex assigned at birth, these questions leave out a patient’s preferred name and pronouns – crucial components of respectful and affirming care, the authors explained.
At a specialty gender clinic, the authors surveyed 204 transgender youths, aged 12-26 years, regarding how their name and pronouns are recorded in their EMR files. Just over half the respondents were under age 18 years (56%), and most were white (86%). Most were transmasculine (59%), with 21% transfeminine and 20% nonbinary.
Most respondents (69%) went by a name other than their legal one, yet only 9% said they were frequently or always asked in clinical settings outside specialty gender centers whether they wanted their preferred name and pronouns noted in the EMR.
A majority (79%), however, said they wanted their name and pronouns noted throughout their EMR. The youths’ preferences varied according to their gender identity and how many people were aware of their gender identity, but not by age, race/ethnicity, or perceived amount of parental support.
Only two-thirds (67%) of 42 transfeminine patients wished their EMR to include their preferred name, compared with most (85%) of 121 transmasculine patients and nearly all (92%) of 37 nonbinary respondents (P = .007). Pronouns preferences were similar: All but one nonbinary respondent wanted their pronouns in the EMR, compared with 84% of transmasculine and 64% of transfeminine respondents (P=.0003).
“It may be that transfeminine patients have more pressure to ‘stay’ their assigned gender,” Dr Breuner said regarding these findings. “ ‘Outness’ may be challenging, and thus they remain in their traditional gender norms, but further research on this theory is warranted.”
Among those who were “out to everyone,” most (88%) wanted their preferred name and pronouns recorded in the EMR, and the proportion was similar for those “out to most.” But only 65% of those “out to few or no one” preferred their name and pronouns be noted in the EMR, a similar proportion for those “out to some.”
Of 7 youths who did not wish to include their name and pronouns throughout their EMR, all but one said they didn’t think it was necessary because they believed they already “passed” well enough as their gender. Just one person said they did not want name and pronouns recorded for confidentiality reasons.
However, confidentiality is still an important consideration particularly for minors, the authors and Dr. Breuner pointed out.
“It is essential to discuss confidentiality with the youth as parents may have access to the medical records younger than 18 years of age,” Dr. Breuner said.
The authors noted the study’s limitation in using a convenience sample but they and Dr. Breuner said that the findings still demonstrate transgender youths’ desire for EMRs to include their name and pronouns.
The research was funded by grants from the National Institutes of Health. The authors had no industry disclosures.

Most transgender and gender nonconforming youth would like their preferred name and pronouns be recorded throughout their EMRs, but very few are ever asked for that identity information outside of gender specialty clinic settings, according to a recent research letter in JAMA Pediatrics.
The findings are not surprising, said Cora Breuner, MD, a professor of pediatrics in adolescent medicine at Seattle Children’s Hospital in Washington, because “we know that use of gender-affirming language when accessing health care is extremely important to transgender youth.”
“Use of gender-affirming language in the health care system is associated with improved mental health outcomes in this population,” Dr Breuner said in an interview.
But the authors of the study noted that EMRs often lack the functions needed to provide gender-affirming care.

Pediatric Dermatology Emergencies
Many pediatric skin conditions can be safely monitored with minimal intervention, but certain skin conditions are emergent and require immediate attention and proper assessment of the neonate, infant, or child. The skin may provide the first presentation of a potentially fatal disease with serious sequelae. Cutaneous findings may indicate the need for further evaluation. Therefore, it is important to differentiate skin conditions with benign etiologies from those that require immediate diagnosis and treatment, as early intervention of some of these conditions can be lifesaving. Herein, we discuss pertinent pediatric dermatology emergencies that dermatologists should keep in mind so that these diagnoses are never missed.
Staphylococcal Scalded Skin Syndrome
Presentation
Staphylococcal scalded skin syndrome (SSSS), or Ritter disease, is a potentially fatal pediatric emergency, especially in newborns.1 The mortality rate for SSSS in the United States is 3.6% to 11% in children.2 It typically presents with a prodrome of tenderness, fever, and confluent erythematous patches on the folds of the skin such as the groin, axillae, nose, and ears, with eventual spread to the legs and trunk.1,2 Within 24 to 48 hours of symptom onset, blistering and fluid accumulation will appear diffusely. Bullae are flaccid, and tangential and gentle pressure on involved unblistered skin may lead to shearing of the epithelium, which is a positive Nikolsky sign.1,2
Causes
Staphylococcal scalded skin syndrome is caused by exfoliative toxins A and B, toxigenic strains of Staphylococcus aureus. Exfoliative toxins A and B are serine proteases that target and cleave desmoglein 1, which binds keratinocytes in the stratum granulosum.1,3 Exfoliative toxins disrupt the adhesion of keratinocytes, resulting in bullae formation and subsequently diffuse sheetlike desquamation.1,4,5 Although up to 30% of the human population are asymptomatically and permanently colonized with nasal S aureus,6 the exfoliative toxins are produced by only 5% of species.1
In neonates, the immune and renal systems are underdeveloped; therefore, patients are susceptible to SSSS due to lack of neutralizing antibodies and decreased renal toxin excretion.4 Potential complications of SSSS are deeper soft-tissue infection, septicemia (blood-borne infection), and fluid and electrolyte imbalance.1,4
Diagnosis and Treatment
The condition is diagnosed clinically based on the findings of tender erythroderma, bullae, and desquamation with a scalded appearance, especially in friction zones; periorificial crusting; positive Nikolsky sign; and lack of mucosal involvement (Figure 1).1 Histopathology can aid in complicated clinical scenarios as well as culture from affected areas, including the upper respiratory tract, diaper region, and umbilicus.1,4 Hospitalization is required for SSSS for intravenous antibiotics, fluids, and electrolyte repletion.
Differential Diagnosis
There are multiple diagnoses to consider in the setting of flaccid bullae in the pediatric population. Stevens-Johnson syndrome or toxic epidermal necrolysis also can present with fever and superficial desquamation or bullae; however, exposure to medications and mucosal involvement often are absent in SSSS (Figure 2).2 Pemphigus, particularly paraneoplastic pemphigus, also often includes mucosal involvement and scalding thermal burns that are often geometric or focal. Epidermolysis bullosa and toxic shock syndrome also should be considered.1
Impetigo
Presentation
Impetigo is the most common bacterial skin infection in children caused by S aureus or Streptococcus pyogenes.7-9 It begins as erythematous papules transitioning to thin-walled vesicles that rapidly rupture and result in honey-crusted papules.7,9,10 Individuals of any age can be affected by nonbullous impetigo, but it is the most common skin infection in children aged 2 to 5 years.7
Bullous impetigo primarily is seen in children, especially infants, and rarely can occur in teenagers or adults.7 It most commonly is caused by the exfoliative toxins of S aureus. Bullous impetigo presents as small vesicles that may converge into larger flaccid bullae or pustules.7-10 Once the bullae rupture, an erythematous base with a collarette of scale remains without the formation of a honey-colored crust.8 Bullous impetigo usually affects moist intertriginous areas such as the axillae, neck, and diaper area8,10 (Figure 3). Complications may result in cellulitis, septicemia, osteomyelitis, poststreptococcal glomerulonephritis associated with S pyogenes, and S aureus–induced SSSS.7-9
Diagnosis
Nonbullous and bullous impetigo are largely clinical diagnoses that can be confirmed by culture of a vesicle or pustular fluid.10 Treatment of impetigo includes topical or systemic antibiotics.7,10 Patients should be advised to keep lesions covered and avoid contact with others until all lesions resolve, as lesions are contagious.9
Eczema Herpeticum
Presentation
Eczema herpeticum (EH), also known as Kaposi varicelliform eruption, is a disseminated herpes simplex virus infection of impaired skin, most commonly in patients with atopic dermatitis (AD).11 Eczema herpeticum presents as a widespread eruption of erythematous monomorphic vesicles that progress to punched-out erosions with hemorrhagic crusting (Figure 4). Patients may have associated fever or lymphadenopathy.12,13
Causes
The number of children hospitalized annually for EH in the United States is approximately 4 to 7 cases per million children. Less than 3% of pediatric AD patients are affected, with a particularly increased risk in patients with severe and earlier-onset AD.12-15 Patients with AD have skin barrier defects, and decreased IFN-γ expression and cathelicidins predispose patients with AD to developing EH.12,16,17
Diagnosis
Viral polymerase chain reaction for herpes simplex virus types 1 and 2 is the standard for confirmatory diagnosis. Herpes simplex virus cultures from cutaneous scrapings, direct fluorescent antibody testing, or Tzanck test revealing multinucleated giant cells also may help establish the diagnosis.11,12,17
Management
Individuals with severe AD and other dermatologic conditions with cutaneous barrier compromise are at risk for developing EH, which is a medical emergency requiring hospitalization and prompt treatment with antiviral therapy such as acyclovir, often intravenously, as death can result if left untreated.11,17 Topical or systemic antibiotic therapy should be initiated if there is suspicion for secondary bacterial superinfection. Patients should be evaluated for multiorgan involvement such as keratoconjunctivitis, meningitis, encephalitis, and systemic viremia due to increased mortality, especially in infants.12,15,16
Langerhans Cell Histiocytosis
Presentation
Langerhans cell histiocytosis (LCH) has a variable clinical presentation and can involve a single or multiple organ systems, including the bones and skin. Cutaneous LCH can present as violaceous papules, nodules, or ulcerations and crusted erosions (Figure 5). The lymph nodes, liver, spleen, oral mucosa, and respiratory and central nervous systems also may be involved.
Langerhans cell histiocytosis affects individuals of any age group but more often is seen in pediatric patients. The incidence of LCH is approximately 4.6 cases per million children.18 The pathogenesis is secondary to pathologic Langerhans cells, characterized as a clonal myeloid malignancy and dysregulation of the immune system.18,19
Diagnosis
A thorough physical examination is essential in patients with suspected LCH. Additionally, diagnosis of LCH is heavily based on histopathology of tissue from the involved organ system(s) with features of positive S-100 protein, CD1a, and CD207, and identification of Birbeck granules.20 Imaging and laboratory studies also are indicated and can include a skeletal survey (to assess osteolytic and organ involvement), a complete hematologic panel, coagulation studies, and liver function tests.18,21
Management
Management of LCH varies based on the organ system(s) involved along with the extent of the disease. Dermatology referral may be indicated in patients presenting with nonresolving cutaneous lesions as well as in severe cases. Single-organ and multisystem disease may require one treatment modality or a combination of chemotherapy, surgery, radiation, and/or immunotherapy.21
Infantile Hemangioma
Presentation
Infantile hemangioma (IH) is the most common benign tumor of infancy and usually is apparent a few weeks after birth. Lesions appear as bright red papules, nodules, or plaques. Deep or subcutaneous lesions present as raised, flesh-colored nodules with a blue hue and bruiselike appearance with or without a central patch of telangiectasia22-24 (Figure 6). Although all IHs eventually resolve, residual skin changes such as scarring, atrophy, and fibrosis can persist.24
The incidence of IH has been reported to occur in up to 4% to 5% of infants in the United States.23,25 Infantile hemangiomas also have been found to be more common among white, preterm, and multiple-gestation infants.25 The proposed pathogenesis of IHs includes angiogenic and vasogenic factors that cause rapid proliferation of blood vessels, likely driven by tissue hypoxia.23,26,27
Diagnosis
Infantile hemangioma is diagnosed clinically; however, immunohistochemical staining showing positivity for glucose transporter 1 also is helpful.26,27 Imaging modalities such as ultrasonography and magnetic resonance imaging also can be utilized to visualize the extent of lesions if necessary.25
Management
Around 15% to 25% of IHs are considered complicated and require intervention.25,27 Infantile hemangiomas can interfere with function depending on location or have potentially fatal complications. Based on the location and extent of involvement, these findings can include ulceration; hemorrhage; impairment of feeding, hearing, and/or vision; facial deformities; airway obstruction; hypothyroidism; and congestive heart failure.25,28 Early treatment with topical or oral beta-blockers is imperative for potentially life-threatening IHs, which can be seen due to large size or dangerous location.28,29 Because the rapid proliferative phase of IHs is thought to begin around 6 weeks of life, treatment should be initiated as early as possible. Initiation of beta-blocker therapy in the first few months of life can prevent functional impairment, ulceration, and permanent cosmetic changes. Additionally, surgery or pulsed dye laser treatment have been found to be effective for skin changes found after involution of IH.25,29
Differential Diagnosis
The differential diagnosis for IH includes vascular malformations, which are present at birth and do not undergo rapid proliferation; sarcoma; and kaposiform hemangioendothelioma, which causes the Kasabach-Merritt phenomenon secondary to platelet trapping. Careful attention to the history of the skin lesion provides good support for diagnosis of IH in most cases.
IgA Vasculitis
Presentation
IgA vasculitis, or Henoch-Schönlein purpura, classically presents as a tetrad of palpable purpura, acute-onset arthritis or arthralgia, abdominal pain, and renal disease with proteinuria or hematuria.30 Skin involvement is seen in almost all cases and is essential for diagnosis of IgA vasculitis. The initial dermatosis may be pruritic and present as an erythematous macular or urticarial wheal that evolves into petechiae, along with palpable purpura that is most frequently located on the legs or buttocks (Figure 7).30-34
IgA vasculitis is an immune-mediated small vessel vasculitis with deposition of IgA in the small vessels. The underlying cause remains unknown, though infection, dietary allergens, drugs, vaccinations, and chemical triggers have been recognized in literature.32,35,36 IgA vasculitis is largely a pediatric diagnosis, with 90% of affected individuals younger than 10 years worldwide.37 In the pediatric population, the incidence has been reported to be 3 to 26.7 cases per 100,000 children.32
Diagnosis
Diagnosis is based on the clinical presentation and histopathology.30 On direct immunofluorescence, IgA deposition is seen in the vessel walls.35 Laboratory testing is not diagnostic, but urinalysis is mandatory to identify involvement of renal vasculature. Imaging studies may be used in patients with abdominal symptoms, as an ultrasound can be used to visualize bowel structure and abnormalities such as intussusception.33
Management
The majority of cases of IgA vasculitis recover spontaneously, with patients requiring hospital admission based on severity of symptoms.30 The primary approach to management involves providing supportive care including hydration, adequate rest, and symptomatic pain relief of the joints and abdomen with oral analgesics. Systemic corticosteroids or steroid-sparing agents such as dapsone or colchicine can be used to treat cutaneous manifestations in addition to severe pain symptoms.30,31 Patients with IgA vasculitis must be monitored for proteinuria or hematuria to assess the extent of renal involvement. Although much more common in adults, long-term renal impairment can result from childhood cases of IgA vasculitis.34
Final Thoughts
Pediatric dermatology emergencies can be difficult to detect and accurately diagnose. Many of these diseases are potential emergencies that that may result in delayed treatment and considerable morbidity and mortality if missed. Clinicians should be aware that timely recognition and diagnosis, along with possible referral to pediatric dermatology, are essential to avoid complications.

Herpes simplex virus cultures from cutaneous scrapings, direct fluorescent antibody testing, or Tzanck test revealing multinucleated giant cells also may help establish the diagnosis.11,12,17
Management
Individuals with severe AD and other dermatologic conditions with cutaneous barrier compromise are at risk for developing EH, which is a medical emergency requiring hospitalization and prompt treatment with antiviral therapy such as acyclovir, often intravenously, as death can result if left untreated.11,17 Topical or systemic antibiotic therapy should be initiated if there is suspicion for secondary bacterial superinfection. Patients should be evaluated for multiorgan involvement such as keratoconjunctivitis, meningitis, encephalitis, and systemic viremia due to increased mortality, especially in infants.12,15,16
Langerhans Cell Histiocytosis
Presentation
Langerhans cell histiocytosis (LCH) has a variable clinical presentation and can involve a single or multiple organ systems, including the bones and skin. Cutaneous LCH can present as violaceous papules, nodules, or ulcerations and crusted erosions (Figure 5). The lymph nodes, liver, spleen, oral mucosa, and respiratory and central nervous systems also may be involved.
Langerhans cell histiocytosis affects individuals of any age group but more often is seen in pediatric patients. The incidence of LCH is approximately 4.6 cases per million children.18 The pathogenesis is secondary to pathologic Langerhans cells, characterized as a clonal myeloid malignancy and dysregulation of the immune system.18,19
Diagnosis
A thorough physical examination is essential in patients with suspected LCH. Additionally, diagnosis of LCH is heavily based on histopathology of tissue from the involved organ system(s) with features of positive S-100 protein, CD1a, and CD207, and identification of Birbeck granules.20 Imaging and laboratory studies also are indicated and can include a skeletal survey (to assess osteolytic and organ involvement), a complete hematologic panel, coagulation studies, and liver function tests.18,21
Management
Management of LCH varies based on the organ system(s) involved along with the extent of the disease. Dermatology referral may be indicated in patients presenting with nonresolving cutaneous lesions as well as in severe cases. Single-organ and multisystem disease may require one treatment modality or a combination of chemotherapy, surgery, radiation, and/or immunotherapy.21
Infantile Hemangioma
Presentation
Infantile hemangioma (IH) is the most common benign tumor of infancy and usually is apparent a few weeks after birth. Lesions appear as bright red papules, nodules, or plaques. Deep or subcutaneous lesions present as raised, flesh-colored nodules with a blue hue and bruiselike appearance with or without a central patch of telangiectasia22-24 (Figure 6). Although all IHs eventually resolve, residual skin changes such as scarring, atrophy, and fibrosis can persist.24
The incidence of IH has been reported to occur in up to 4% to 5% of infants in the United States.23,25 Infantile hemangiomas also have been found to be more common among white, preterm, and multiple-gestation infants.25 The proposed pathogenesis of IHs includes angiogenic and vasogenic factors that cause rapid proliferation of blood vessels, likely driven by tissue hypoxia.23,26,27
Diagnosis
Infantile hemangioma is diagnosed clinically; however, immunohistochemical staining showing positivity for glucose transporter 1 also is helpful.26,27 Imaging modalities such as ultrasonography and magnetic resonance imaging also can be utilized to visualize the extent of lesions if necessary.25
Management
Around 15% to 25% of IHs are considered complicated and require intervention.25,27 Infantile hemangiomas can interfere with function depending on location or have potentially fatal complications. Based on the location and extent of involvement, these findings can include ulceration; hemorrhage; impairment of feeding, hearing, and/or vision; facial deformities; airway obstruction; hypothyroidism; and congestive heart failure.25,28 Early treatment with topical or oral beta-blockers is imperative for potentially life-threatening IHs, which can be seen due to large size or dangerous location.28,29 Because the rapid proliferative phase of IHs is thought to begin around 6 weeks of life, treatment should be initiated as early as possible. Initiation of beta-blocker therapy in the first few months of life can prevent functional impairment, ulceration, and permanent cosmetic changes. Additionally, surgery or pulsed dye laser treatment have been found to be effective for skin changes found after involution of IH.25,29
Differential Diagnosis
The differential diagnosis for IH includes vascular malformations, which are present at birth and do not undergo rapid proliferation; sarcoma; and kaposiform hemangioendothelioma, which causes the Kasabach-Merritt phenomenon secondary to platelet trapping. Careful attention to the history of the skin lesion provides good support for diagnosis of IH in most cases.
IgA Vasculitis
Presentation
IgA vasculitis, or Henoch-Schönlein purpura, classically presents as a tetrad of palpable purpura, acute-onset arthritis or arthralgia, abdominal pain, and renal disease with proteinuria or hematuria.30 Skin involvement is seen in almost all cases and is essential for diagnosis of IgA vasculitis. The initial dermatosis may be pruritic and present as an erythematous macular or urticarial wheal that evolves into petechiae, along with palpable purpura that is most frequently located on the legs or buttocks (Figure 7).30-34
IgA vasculitis is an immune-mediated small vessel vasculitis with deposition of IgA in the small vessels. The underlying cause remains unknown, though infection, dietary allergens, drugs, vaccinations, and chemical triggers have been recognized in literature.32,35,36 IgA vasculitis is largely a pediatric diagnosis, with 90% of affected individuals younger than 10 years worldwide.37 In the pediatric population, the incidence has been reported to be 3 to 26.7 cases per 100,000 children.32
Diagnosis
Diagnosis is based on the clinical presentation and histopathology.30 On direct immunofluorescence, IgA deposition is seen in the vessel walls.35 Laboratory testing is not diagnostic, but urinalysis is mandatory to identify involvement of renal vasculature. Imaging studies may be used in patients with abdominal symptoms, as an ultrasound can be used to visualize bowel structure and abnormalities such as intussusception.33
Management
The majority of cases of IgA vasculitis recover spontaneously, with patients requiring hospital admission based on severity of symptoms.30 The primary approach to management involves providing supportive care including hydration, adequate rest, and symptomatic pain relief of the joints and abdomen with oral analgesics. Systemic corticosteroids or steroid-sparing agents such as dapsone or colchicine can be used to treat cutaneous manifestations in addition to severe pain symptoms.30,31 Patients with IgA vasculitis must be monitored for proteinuria or hematuria to assess the extent of renal involvement. Although much more common in adults, long-term renal impairment can result from childhood cases of IgA vasculitis.34
Final Thoughts
Pediatric dermatology emergencies can be difficult to detect and accurately diagnose. Many of these diseases are potential emergencies that that may result in delayed treatment and considerable morbidity and mortality if missed. Clinicians should be aware that timely recognition and diagnosis, along with possible referral to pediatric dermatology, are essential to avoid complications.
Many pediatric skin conditions can be safely monitored with minimal intervention, but certain skin conditions are emergent and require immediate attention and proper assessment of the neonate, infant, or child. The skin may provide the first presentation of a potentially fatal disease with serious sequelae. Cutaneous findings may indicate the need for further evaluation. Therefore, it is important to differentiate skin conditions with benign etiologies from those that require immediate diagnosis and treatment, as early intervention of some of these conditions can be lifesaving. Herein, we discuss pertinent pediatric dermatology emergencies that dermatologists should keep in mind so that these diagnoses are never missed.
Staphylococcal Scalded Skin Syndrome
Presentation
Staphylococcal scalded skin syndrome (SSSS), or Ritter disease, is a potentially fatal pediatric emergency, especially in newborns.1 The mortality rate for SSSS in the United States is 3.6% to 11% in children.2 It typically presents with a prodrome of tenderness, fever, and confluent erythematous patches on the folds of the skin such as the groin, axillae, nose, and ears, with eventual spread to the legs and trunk.1,2 Within 24 to 48 hours of symptom onset, blistering and fluid accumulation will appear diffusely. Bullae are flaccid, and tangential and gentle pressure on involved unblistered skin may lead to shearing of the epithelium, which is a positive Nikolsky sign.1,2
Causes
Staphylococcal scalded skin syndrome is caused by exfoliative toxins A and B, toxigenic strains of Staphylococcus aureus. Exfoliative toxins A and B are serine proteases that target and cleave desmoglein 1, which binds keratinocytes in the stratum granulosum.1,3 Exfoliative toxins disrupt the adhesion of keratinocytes, resulting in bullae formation and subsequently diffuse sheetlike desquamation.1,4,5 Although up to 30% of the human population are asymptomatically and permanently colonized with nasal S aureus,6 the exfoliative toxins are produced by only 5% of species.1
In neonates, the immune and renal systems are underdeveloped; therefore, patients are susceptible to SSSS due to lack of neutralizing antibodies and decreased renal toxin excretion.4 Potential complications of SSSS are deeper soft-tissue infection, septicemia (blood-borne infection), and fluid and electrolyte imbalance.1,4
Diagnosis and Treatment
The condition is diagnosed clinically based on the findings of tender erythroderma, bullae, and desquamation with a scalded appearance, especially in friction zones; periorificial crusting; positive Nikolsky sign; and lack of mucosal involvement (Figure 1).1 Histopathology can aid in complicated clinical scenarios as well as culture from affected areas, including the upper respiratory tract, diaper region, and umbilicus.1,4 Hospitalization is required for SSSS for intravenous antibiotics, fluids, and electrolyte repletion.
Differential Diagnosis
There are multiple diagnoses to consider in the setting of flaccid bullae in the pediatric population. Stevens-Johnson syndrome or toxic epidermal necrolysis also can present with fever and superficial desquamation or bullae; however, exposure to medications and mucosal involvement often are absent in SSSS (Figure 2).2 Pemphigus, particularly paraneoplastic pemphigus, also often includes mucosal involvement and scalding thermal burns that are often geometric or focal. Epidermolysis bullosa and toxic shock syndrome also should be considered.1
Impetigo
Presentation
Impetigo is the most common bacterial skin infection in children caused by S aureus or Streptococcus pyogenes.7-9 It begins as erythematous papules transitioning to thin-walled vesicles that rapidly rupture and result in honey-crusted papules.7,9,10 Individuals of any age can be affected by nonbullous impetigo, but it is the most common skin infection in children aged 2 to 5 years.7
Bullous impetigo primarily is seen in children, especially infants, and rarely can occur in teenagers or adults.7 It most commonly is caused by the exfoliative toxins of S aureus. Bullous impetigo presents as small vesicles that may converge into larger flaccid bullae or pustules.7-10 Once the bullae rupture, an erythematous base with a collarette of scale remains without the formation of a honey-colored crust.8 Bullous impetigo usually affects moist intertriginous areas such as the axillae, neck, and diaper area8,10 (Figure 3). Complications may result in cellulitis, septicemia, osteomyelitis, poststreptococcal glomerulonephritis associated with S pyogenes, and S aureus–induced SSSS.7-9
Diagnosis
Nonbullous and bullous impetigo are largely clinical diagnoses that can be confirmed by culture of a vesicle or pustular fluid.10 Treatment of impetigo includes topical or systemic antibiotics.7,10 Patients should be advised to keep lesions covered and avoid contact with others until all lesions resolve, as lesions are contagious.9
Eczema Herpeticum
Presentation
Eczema herpeticum (EH), also known as Kaposi varicelliform eruption, is a disseminated herpes simplex virus infection of impaired skin, most commonly in patients with atopic dermatitis (AD).11 Eczema herpeticum presents as a widespread eruption of erythematous monomorphic vesicles that progress to punched-out erosions with hemorrhagic crusting (Figure 4). Patients may have associated fever or lymphadenopathy.12,13
Causes
The number of children hospitalized annually for EH in the United States is approximately 4 to 7 cases per million children. Less than 3% of pediatric AD patients are affected, with a particularly increased risk in patients with severe and earlier-onset AD.12-15 Patients with AD have skin barrier defects, and decreased IFN-γ expression and cathelicidins predispose patients with AD to developing EH.12,16,17
Diagnosis
Viral polymerase chain reaction for herpes simplex virus types 1 and 2 is the standard for confirmatory diagnosis. Herpes simplex virus cultures from cutaneous scrapings, direct fluorescent antibody testing, or Tzanck test revealing multinucleated giant cells also may help establish the diagnosis.11,12,17
Management
Individuals with severe AD and other dermatologic conditions with cutaneous barrier compromise are at risk for developing EH, which is a medical emergency requiring hospitalization and prompt treatment with antiviral therapy such as acyclovir, often intravenously, as death can result if left untreated.11,17 Topical or systemic antibiotic therapy should be initiated if there is suspicion for secondary bacterial superinfection. Patients should be evaluated for multiorgan involvement such as keratoconjunctivitis, meningitis, encephalitis, and systemic viremia due to increased mortality, especially in infants.12,15,16

Practice Points
- Staphylococcal scalded skin syndrome, impetigo, eczema herpeticum, Langerhans cell histiocytosis, infantile hemangiomas, and IgA vasculitis all present potential emergencies in pediatric patients in dermatologic settings.
- Early and accurate identification and management of these entities is critical to avoid short-term and long-term negative sequalae.
Emollients didn’t prevent atopic dermatitis in high-risk infants
The use of
including those at high risk, in two new clinical trials.The BEEP (Barrier Enhancement for Eczema Prevention) study compared the rates of AD among infants identified as at risk of AD because of family history who had daily applications of emollients (Diprobase cream or Doublebase gel) for the first year of life, compared with a standard skin care group. PreventADALL (Preventing Atopic Dermatitis and Allergies in Children) is a randomized, primary-prevention study conducted in Norway and Sweden that randomized infants into one of four groups: controls whose parents followed regular skin care advice and nutrition guidelines; those who received skin emollients (the addition of emulsified oil to their bath and application of facial cream on at least 4 days a week from age 2 weeks to 8 months); those who received early complementary feeding of peanut, cow’s milk, wheat, and egg introduced between aged 12 and 16 weeks; and a group that combined both the emollient and diet interventions.
Neither of the studies, published in the Lancet, found statistically significant differences in AD rates between the intervention and control groups.
The results put a damper on hopes raised by previous studies that included two small pilot studies, which found that daily use of leave-on emollients in infants considered at high risk of AD prevented the development of AD (J Allergy Clin Immunol 2014 Oct;134:824-30.e6; J Allergy Clin Immunol Oct 2014;134:818-23).
“It was maybe a little bit overly hopeful to think that we could just moisturize and prevent such a complex disorder,” Robert Sidbury, MD, chief of dermatology at Seattle Children’s Hospital, said in an interview. He emphasized that the studies only addressed emollients as a preventative, and that “there’s no question that emollients are still critical for the therapy of eczema.”
Bruce Brod, MD, clinical professor of dermatology at the University of Pennsylvania, Philadelphia, suggested that homogeneous patient populations or insufficient numbers might explain the negative findings. PreventADALL drew patients from Norway and Sweden, while BEEP recruited from the United Kingdom. “They’re important studies, but I think they still lend themselves to further studies with different patient populations and larger groups of patients,” Dr. Brod said in an interview.
BEEP was headed by Joanne Chalmers, PhD, and Hywel Williams, DSc, of the Centre of Evidence-Based Dermatology at the University of Nottingham (England). Håvard Ove Skjerven, PhD, and Karin C Lødrup Carlsen, PhD, of Oslo University Hospital led the PreventADALL study.
The BEEP study randomized 1,394 newborns at 16 sites in the United Kingdom to daily emollient treatment with standard skin care, or standard skin care alone. At one year, compliance was 74% in the intervention group. At age 2, 23% of the intervention group had AD, compared with 25% of controls (hazard ratio, 0.95; P =.61). Skin infections were also higher in the treatment arm (mean, 0.23 per year vs. 0.15 per year; adjusted incidence ratio, 1.55; 95% confidence interval, 1.15-2.09).
“Our study does not support the use of emollients for preventing eczema in high-risk infants, a finding supported by PreventADALL, another large trial using a skin barrier enhancing intervention,” they concluded. Their data “relate only to prevention of eczema and do not directly challenge the practice of using emollients as first-line treatment for eczema.”
In the PreventADALL study, 2,397 newborn infants born between 2015 and 2017 were randomized to one of the four groups. Use of facial cream and emollients during bathing began at 2 weeks, and early complementary feeding of peanut, cow’s milk, wheat, and egg at 3-4 months. The frequency of AD at aged 12 months in the control group was 8%, compared with 11% in the skin-intervention group, 9% in the food-intervention group, and 5% in the combined-intervention group.
These differences were not statistically significant, and “the primary hypothesis that either skin intervention or food intervention reduced atopic dermatitis were not confirmed,” the authors wrote. Parental atopy did not influence the effects of the interventions. Their results were in line with the BEEP results, and the authors “cannot recommend these interventions as primary prevention strategies.”
The researchers will continue to follow children until age 3 years to evaluate the food allergy rates, if the combined-treatment group experiences a long-term benefit. Adherence to the protocol was poor, with 44% compliance with the facial cream application and 27% compliance with bathing emollients; 32% fully adhered to the diet protocols.
The studies were funded by the National Institute for Health Research Health Technology Assessment (BEEP); and a range of public and private funders (PreventADALL). One author of the PreventADALL study disclosed receiving honoraria for presentations from several pharmaceutical companies, and one author received honoraria for presentations from Thermo Fisher Scientific; the rest had no disclosures. Dr. Sidbury has been an investigator for Regeneron. Dr. Brod had no relevant financial disclosures.

The “null findings” of these two studies were “unexpected,” Kirsten P. Perrett, MBBS, Phd, and Rachel L. Peters, PhD, of the department of population allergy at Murdoch Children’s Research Institute, Parkville, Australia, wrote in an accompanying editorial. They noted that emollients are used regularly in the management of atopic dermatitis, where they help maintain the skin barrier and reduce the need for anti-inflammatory therapies.
These two large prevention studies were “prompted” by the results of small, proof-of-concept pilot studies, which “provided strong efficacy signals for the hypothesis that daily emollient use could prevent atopic dermatitis,” they wrote. But the two studies “found no evidence that daily emollient use in either a population-based or high-risk cohort of infants during the first year of life could delay, suppress, or prevent atopic dermatitis.” The lower incidence of atopic dermatitis among those in the dietary and emollient combination, compared with controls (5% vs. 8%) in PreventADALL, could be a chance finding.
The large, randomized Prevention of Eczema by a Barrier Lipid Equilibrium Strategy (PEBBLES) trial is ongoing to confirm results from a small study suggesting the efficacy of a ceramide-dominant emollient. But the PreventADALL study showed low compliance, suggesting that this intervention, if effective, a twice-daily emollient regimen may be tough to implement. “At this stage, emollients should not be recommended for the primary prevention of atopic dermatitis in infants,” they concluded.
Dr. Perrett and Dr. Peters declared no competing interests. Their comments appeared in the Lancet (2020 Feb 19. doi: 10.1016/S0140-6736[19]33174-5).

Intervention improves antibiotics use in UTIs
A multifaceted intervention significantly changed clinicians’ use of antibiotics to treat urinary tract infections (UTIs) in children, according to data from more than 2,000 cases observed between January 2014 and September 2018.
“Changing clinicians’ antibiotic prescribing practices can be challenging; barriers to change include lack of awareness of new evidence, competing clinical demands, and concern about treatment failure,” wrote Matthew F. Daley, MD, of Kaiser Permanente Colorado, Aurora, and colleagues in Pediatrics.
To promote judicious antibiotic use, the researchers designed an intervention including the development of new local UTI guidelines; a live, case-based educational session; emailed knowledge assessments before and after the session; and a specific UTI order set in the EHR.
The researchers divided the study period into a preintervention period (January 1, 2014, to April 25, 2017) and a postintervention period (April 26, 2017, to September 30, 2018). They collected data on 2,142 incident outpatient UTIs; 1,636 from the preintervention period and 506 from the postintervention period. The patients were younger than 18 years and older than 60 days, and children with complicated urologic or neurologic conditions were excluded.
(P less than .0001). In particular, the use of first-line, narrow spectrum cephalexin increased significantly from 29% during the preintervention period to 53% during the postintervention period (P less than .0001). In addition, use of broad spectrum cefixime decreased from 17% during the preintervention period to 3% during the postintervention period (P less than .0001). These changes in prescribing patterns continued through the end of the study period, the researchers said.
The study was limited by several factors, notably that “the interrupted time-series design prevents us from inferring that the intervention caused the observed change in practice,” the researchers wrote. However, other factors including the immediate change in prescribing patterns after the intervention, multiple time points, large sample size, and consistent UTI case mix support the impact of the intervention, they suggested. Although the results might not translate completely to other settings, “developing a UTI-specific EHR order set is relatively straightforward” and might be applied elsewhere, they noted.
“Despite the limitations inherent in a nonexperimental study design, the methods and interventions developed in the current study may be informative to other learning health systems and other content areas when conducting organization-wide quality improvement initiatives,” they concluded.
The study was supported by unrestricted internal resources from the Colorado Permanente Medical Group. The researchers had no financial conflicts to disclose.
