“When ZIKV [Zika virus] infection is acquired in utero, it may be associated with epilepsy, and we characterized aspects of this complication in a study performed at our referral center,” wrote Hélio van der Linden Jr., MD, of Dr. Henrique Santillo Rehabilitation and Readaptation Center in Goiânia, Brazil, and colleagues in a letter to the editor published in the New England Journal of Medicine.

The researchers reviewed data from 141 infants aged 1-14 months with a median age of 9 months and Zika virus infection confirmed by laboratory analysis; 55% were girls.

The prevalence of epilepsy was 67%, with a mean age at onset of 4.9 months. Based on data provided by parents, 74% of the children experienced seizures at 6 months of age or younger.

Overall, 77% of the infants experienced a single type of seizure. Epileptic spasms, the most common type, occurred in 72% of infants, followed by focal motor seizure (21%) and tonic seizures (4%).

All 95 epileptic infants were treated with antiepileptic medications and 62 (65%) achieved remission. Of those in remission, 24 (39%) received monotherapy and 38 (61%) received polytherapy. The drugs most associated with seizure control were vigabatrin, levetiracetam, valproate, and phenobarbital.

The prevalence of epilepsy in this study was higher than that seen in previous studies, and most patients had early-onset, drug-resistant epilepsy, the researchers noted. However, burst-suppression patterns and hypsarrhythmia on EEG predicted more severe disease and suggest that epilepsy might complicate cases of congenital Zika infection, they said.

The researchers had no financial conflicts to disclose.

Children and adolescents who moved longer distances or more frequently before 16 years of age were significantly more likely to develop psychosis in early adulthood than were those with less residential mobility, according to data from about 1.4 million children and adolescents in Sweden.

Data from previous studies have supported a link between childhood residential mobility and subsequent nonaffective psychoses, but no research has addressed the effects in later adolescence and young adulthood until now, wrote Ceri Price of Cardiff (Wales) University and colleagues.

In a study published in JAMA Psychiatry, the researchers reviewed data from a population-based cohort of individuals who were born in Sweden between Jan. 1, 1982, and Dec. 31, 1995, and lived in Sweden at age 16 years. The participants were followed from their 16th birthdays until a diagnosis of a nonaffective psychotic disorder, death, censorship because of emigration, or Dec. 31, 2011 – whichever came first.

Overall, the most sensitive range for an association between moving and psychosis was ages 16-19 years; the adjusted hazard ratio for a nonaffective psychotic disorder was 1.99 for participants who moved each year between ages 16 and 19 years, compared with those who never moved. In addition, moving greater distances before 16 years of age was independently associated with an increased risk of nonaffective psychosis (HR, 1.11) and the data suggested a nonlinear threshold effect when the distance moved exceeded 30 km.

A total of 4,537 individuals had a nonaffective psychotic disorder at a median 21 years of age, and a dose-response relationship emerged between more frequent moves and increased risk of nonaffective psychosis after controlling for confounding variables.

By contrast, a single move in young adulthood was not associated with increased psychosis risk, but moving at least four times during young adulthood was associated with an increased risk (adjusted HR, 1.82).

The study findings were strengthened by the longitudinal design and large population, but they were limited by several factors, including an absence of data on other adverse childhood experiences, such as family discord; peer relationships, such as friendships and bullying; and information on school changes and the disruption of peer relationships, the researchers wrote.

However, the results support the theory that psychosis risk can be affected by the disruption of social networks, peer support, and identity formation that occurs when children and adolescents move, and these results have potential implications for child health services and social policy, they noted.

“It is important that health, social, and educational practitioners ensure that children and adolescents who are newly resident to their neighborhoods receive adequate support to minimize the risks of adverse outcomes during adulthood, and every effort should be made to ensure the effective transfer of care for highly mobile children who are already in contact with health and social services,” they said.

The researchers had no financial conflicts to disclose. The study was supported in part by the Wellcome Trust and the Royal Society.

Screen women for cervical cancer with basic cytology starting at age 21 years, and consider adding high-risk human papillomavirus (hrHPV) testing alone or with cytology for women aged 30 years and older, the U.S. Preventive Services Task Force recommended in an updated statement on cervical cancer screening .

The statement, accompanying evidence report, and a modeling study were published online in JAMA.

Cervical cancer deaths in the United States have declined from 2.8 deaths per 100,000 women in 2000 to 2.3 deaths per 100,000 women in 2015 because of the adoption of widespread screening, according to Susan J. Curry, PhD., of the University of Iowa, Iowa City, and her colleagues in the USPSTF (JAMA. 2018 Aug 21. doi: 10.1001/jama.2018.10897.

Based on the latest evidence and the modeling study, the USPSTF gives an A recommendation to screening women aged 21-29 years for cervical cancer every 3 years with cervical cytology alone. The task force also gives an A to screening women aged 30-65 years every 5 years with either hrHPV testing alone or in combination with cytology.

The task force recommends against screening (D recommendation) for women younger than 21 years, older than 65 years with a history of screening and low cervical cancer risk, and women who have had hysterectomies with removal of the cervix and no history of cervical cancer risk.

To update the previous recommendations issued in 2012, the task force reviewed the latest evidence and commissioned a modeling study to help determine the best screening strategies in terms of age, screening intervals, and risks vs. benefits.

In the model, researchers assessed 19 strategies for cervical cancer screening based on a hypothetical cohort of women who began screening at 21 years of age.

Overall, the different strategies were similar in effectiveness, but primary hrHPV testing and alternative cotesting were slightly more effective: Cervical cancer deaths ranged from 0.23 to 0.29 deaths per 1,000 women in strategies involving hrHPV testing or cotesting, vs. 0.30 to 0.76 deaths per 1,000 women for strategies based on the current guidelines.

In addition, switching the age of hrHPV testing from 25 years to 30 years and using a 5-year screening interval showed the most effectiveness in terms of risks vs. harms, wrote Jane K. Kim, PhD, of Harvard University, Boston, and her colleagues (JAMA. 2018 Aug 21. doi: 10.1001/jama.2017.19872). “Switching from cytology to 5-year primary hrHPV testing at age 30 years (strategy 14) was associated with a ratio of 640 colposcopies per cancer case averted; earlier switch ages required a greater number of colposcopies per cancer case averted.”

The recommendations also were supported by an evidence report including eight randomized, controlled trials of 410,556 women, five cohort studies of 402,615 women, and a meta-analysis of individual participant data including 176,464 women.

The evidence report sought to address the benefits and harms of cervical cancer screening using hrHPV screening alone as the primary screening method or paired with cytology (cotesting), compared with primary screening using cytology alone.

Overall, both hrHPV and hrHPV plus cytology were associated with higher rates of false-positives and colposcopy compared with cytology alone, “which could lead to more treatments with potential harms,” wrote Joy Melnikow, MD, of the University of California, Davis, and her colleagues (JAMA. 2018 Aug 21. doi: 10.1001/jama.2018.10400.

In addition, hrHPV testing yielded higher rates of positive cervical intraepithelial neoplasia, compared with cytology alone as initial screening.

However, further research is needed to address the impact of any cervical cancer screening strategies in populations with limited access to health care and screening, the researchers noted.

The updated USPSTF recommendations are largely in line with those issued by leading women’s health organizations including the American College of Obstetricians and Gynecologists, ASCCP, and the Society for Gynecologic Oncology, according to a joint statement.

“With a number of screening options now available, the new guidelines emphasize the importance of the patient-provider shared decision-making process to assist women in making an informed choice about which screening method is most suitable for them,” according to the statement, “However, more importantly, there needs to be a continued effort to ensure all women are adequately screened because a significant number of women in the country are not. It’s also essential for women to have access to all of the tests and that they are appropriately covered by insurance companies.

“We hope the USPSTF recommendations foster more discussions between patients and providers about cervical cancer screening, promote opportunities for patient education on the benefits and safety of HPV vaccination for cervical cancer prevention and encourage providers to offer HPV vaccines in their offices,” the statement noted.

The USPSTF research was funded by the Agency for Healthcare Research and Quality. The researchers for the modeling report were supported in part by a National Cancer Institute grant. The researchers had no relevant financial conflicts to disclose.

Nighttime media use was associated with less sleep, as well as self-reported anxiety and depression, in teens with attention-deficit/hyperactivity disorder, based on data from 81 adolescents.

“This is the first study to document an association between nighttime media use and more sleep problems and internalizing symptoms in adolescents diagnosed with ADHD,” wrote Stephen P. Becker, PhD, of the University of Cincinnati and colleagues.

Although previous research has addressed the impact of screen time on sleep, anxiety, and depression in children and teens, the impact on adolescents with conditions such as ADHD has not been well studied, the researchers noted.

In a study published in Sleep Medicine, the researchers conducted a study of 81 adolescents aged 13-17 years who met diagnostic criteria for ADHD. The School Sleep Habits Survey (SSHS) was used to measure sleep patterns based on self-reports, and parents reported on teens’ sleep using the Sleep Disturbance Scale for Children. In addition, several other tools that measured ADHD symptoms, daytime sleepiness, anxiety, and depression were administered to both the teens and their parents.

The researchers assessed the number of technologies in each participant’s bedroom and the total hours of electronic media use at night, defined as after 9:00 p.m.

Overall, approximately 60% of the teens in the sample reported more than 4 hours of nighttime media use; 63% reported less than 8 hours of sleep on school nights, but this figure reached 76% when parent reports of teens’ sleep was used. When the teens’ self-reports were used, media use was not significantly different between those who had less than 8 hours of sleep vs. those who had 8 hours or more (5.85 vs. 4.39 hours of nighttime media use). But their parents’ reports told another story. In the parent reports, media use was significantly higher in the short sleepers vs. long sleepers (6.12 vs. 2.65 hours of nighttime media use).

After controlling for factors including age, sex, pubertal stage, use of stimulant medication, and severity of ADHD symptoms, nighttime media use was significantly associated with shorter sleep duration, the researchers said.

Nighttime media use also was significantly associated with greater adolescent-reported depressive symptoms, total anxiety symptoms overall, and panic symptoms in particular, as well as with parent-reported generalized anxiety symptoms.

The study findings were limited by several factors including the cross-sectional design, the lack of an objective sleep measure, and the lack of non-ADHD controls, the researchers noted. Also, the researchers were unable to measure parental control over teen media use or to examine different types of media use, including media multitasking (such as texting while video gaming).

However, the findings “suggest that it is important for clinicians to consider nighttime media use when assessing and treating adolescent ADHD, specifically regarding sleep issues and co-occurring depression and anxiety,” they said.

The researchers had no financial conflicts to disclose. The study was funded by grants from the National Institutes of Mental Health.

“This is the first study to document an association between nighttime media use and more sleep problems and internalizing symptoms in adolescents diagnosed with ADHD,” wrote Stephen P. Becker, PhD, of the University of Cincinnati and colleagues.

Although previous research has addressed the impact of screen time on sleep, anxiety, and depression in children and teens, the impact on adolescents with conditions such as ADHD has not been well studied, the researchers noted.

In a study published in Sleep Medicine, the researchers conducted a study of 81 adolescents aged 13-17 years who met diagnostic criteria for ADHD. The School Sleep Habits Survey (SSHS) was used to measure sleep patterns based on self-reports, and parents reported on teens’ sleep using the Sleep Disturbance Scale for Children. In addition, several other tools that measured ADHD symptoms, daytime sleepiness, anxiety, and depression were administered to both the teens and their parents.

The researchers assessed the number of technologies in each participant’s bedroom and the total hours of electronic media use at night, defined as after 9:00 p.m.

Overall, approximately 60% of the teens in the sample reported more than 4 hours of nighttime media use; 63% reported less than 8 hours of sleep on school nights, but this figure reached 76% when parent reports of teens’ sleep was used. When the teens’ self-reports were used, media use was not significantly different between those who had less than 8 hours of sleep vs. those who had 8 hours or more (5.85 vs. 4.39 hours of nighttime media use). But their parents’ reports told another story. In the parent reports, media use was significantly higher in the short sleepers vs. long sleepers (6.12 vs. 2.65 hours of nighttime media use).

After controlling for factors including age, sex, pubertal stage, use of stimulant medication, and severity of ADHD symptoms, nighttime media use was significantly associated with shorter sleep duration, the researchers said.

Nighttime media use also was significantly associated with greater adolescent-reported depressive symptoms, total anxiety symptoms overall, and panic symptoms in particular, as well as with parent-reported generalized anxiety symptoms.

The study findings were limited by several factors including the cross-sectional design, the lack of an objective sleep measure, and the lack of non-ADHD controls, the researchers noted. Also, the researchers were unable to measure parental control over teen media use or to examine different types of media use, including media multitasking (such as texting while video gaming).

Elementary school girls with particular emotional and behavioral symptoms, including irritability, were significantly more likely to experience anxiety disorders in adolescence and young adulthood, based on data from a network analysis of 932 girls.

Data from previous studies suggest that targeting emotional problems in early childhood might prevent mental health disorders in young adults, wrote Alexandra Rouquette, MD, PhD, of Paris-Saclay University, Paris, and her colleagues. “However, these interventions are challenging to implement because we lack knowledge on which specific childhood symptoms have predictive associations with adult psychopathologic disorders,” they said.

In the study, published in JAMA Psychiatry, the researchers used data from an ongoing longitudinal prospective analysis of kindergarten children in the Canadian province of Quebec to assess potential “bridge symptoms,” defined as those that might affect the development of anxiety later in life. The study population included 932 girls whose parents completed the Social Behavior Questionnaire (SBQ) at baseline when the girls were 6 years old, and again at ages 8 and 10 years. Of these, 780 participants underwent screening for mental health disorders at age 15 and/or 22 years.

Of the 780 participants assessed at follow-up, 270 (35%) had developed at least one anxiety disorder, and 128 (16%) had developed at least one diagnosis of major depression or another depressive disorder.

The researchers used a network analysis technique to review 33 items in the SBQ and how they related to future anxiety disorders. They identified five bridge symptoms – irritability, blaming others, not being liked by others, frequent crying, and solitary behavior – as having “a distinctive position in the network because most of the direct relationships between the disruptive and internalized communities transited through them.”

In addition, children who were disobedient, irritable, and not liked by others had the strongest and earliest association with anxiety disorders over time, the researchers said. By contrast, the kicks disruptive symptom in early childhood was a negative predictor of anxiety disorders at follow-up.

The study findings were limited by several factors, including the relatively small study population, the number of statistical tests performed, and the challenges of identifying anxiety disorders at follow-up. However, the results support the potential role of childhood bridge symptoms in later life anxiety, the researchers said. “Clinicians may wish to focus on these bridge symptoms when assessing patients,” they noted, because those symptoms could be “early targets in disease-prevention and health-promotion interventions.”

The researchers had no financial conflicts to disclose. The study was funded by a grant to Dr. Rouquette from the OpenHealth Institute.

Early detection of small cell lung cancer by low-dose CT had no significant impact on patient survival, based on data from a randomized trial.

windcatcher/Thinkstock.com

Although early detection of small-cell lung cancer might improve outcomes for patients given the metastatic nature of the disease, previous studies on the value and impact of low-dose CT have been divergent, wrote Anish Thomas, MD, of the National Cancer Institute and his colleagues.

In a study published in Chest, the researchers reviewed characteristics of low-dose CT–detected small cell lung cancer (SCLC) in the randomized National Lung Screening Trial (NLST). The trial compared low-dose CT (LDCT) with chest radiography to assess patients at high risk for developing lung cancer. The study population included adults aged 55-74 years with a history of smoking of at least 30 pack-years, and former smokers who had quit within the past 15 years.

A total of 26,722 participants were randomized to the LDCT treatment arm with a median follow-up of 6.5 years; 143 SCLC cases and 926 non–small cell lung cancer (NSCLC) cases were identified in this group.

Of the 143 SCLC cases, 49 (34.2%) were screen detected, 15 (10.5%) were interval detected and 79 (55.2%) were not screened or were identified post screening.

A cancer was defined as screen detected if it was diagnosed within 1 year of a positive screening or diagnosed after a longer period but with no time gap between diagnostic procedures of more than 1 year; an interval cancer was diagnosed within a year of a negative screen, and non-screened cancers were those found in patients who received no NLST screening or other post screening.

Significantly more of the SCLC cases were at stage III or IV than the NSCLC cases (86% vs. 36%). Unfavorable stage III or IV lung cancers were identified in 80% of screen detected, 86% of interval detected, and 90% of nonscreened or postscreened cases.

In addition, 31 (63%) of the 49 screen-detected SCLC cases had at least one noncalcified nodule in the cancer lobe and 24 (49%) had a single NCN in the cancer lobe.

The 3-year cancer-specific survival rates were not significantly different for screen-detected, interval-detected, and nonscreened or postscreened cases (15.3%, 20.0%, and 13.8%, respectively).

“As expected, the majority of SCLC were late-stage cancers, but surprisingly the unfavorable stage distribution was present regardless of whether the cancer was screen-, interval- or post-screen detected,” the researchers noted.

The findings differed from the results of previous smaller studies showing more favorable stage distribution for SCLC cases detected by LDCT, but this difference may be accounted for by various factors including study populations that were smaller, younger, and lacking well-defined risk factors, the researchers said.

“Our findings underscore and provide further granularity to the premise that SCLC is a very aggressive neoplasm, and contrary to smaller prior studies, indicate that LDCT is an ineffective tool to screen for SCLC,” they said. “If early detection of SCLC were to be realistic, it would need to be detected before [lesions] are visible on LDCT,” they emphasized.

The study was supported in part by the National Cancer Institute. The researchers had no financial conflicts to disclose.

Teens who were exposed to any type of secondhand tobacco smoke were significantly more likely to visit emergency departments and to have more such visits, compared with unexposed controls, based on data from more than 7,000 adolescents.

Approximately 35% of U.S. teens spent more than an hour exposed to secondhand smoke in a given week, wrote Ashley L. Merianos, PhD, of the University of Cincinnati and her colleagues.

In a study published in Pediatrics, the researchers conducted a secondary analysis of nonsmoking adolescents aged 12-17 years who had not been diagnosed with asthma and who were part of the PATH (Population Assessment of Tobacco and Health) study, a longitudinal cohort trial of tobacco use behavior and related health outcomes in adolescents and adults in the United States. The data were collected between Oct. 3, 2014, and Oct. 30, 2015. The researchers reviewed three main measures of tobacco smoke exposure (TSE): living with a smoker, being exposed to secondhand smoke at home, and being exposed to secondhand smoke for an hour or more in the past 7 days.

Overall, teens who lived with a smoker, had secondary exposure at home, or had at least 1 hour of TSE had significantly more emergency department and/or urgent care visits (mean ranged from 1.62 to 1.65), compared with unexposed peers (mean visits ranged from 1.42 to 1.48). Those who both lived with a smoker and had at least 1 hour of TSE exposure were significantly more likely to visit an ED or urgent care center.

In addition, teens who lived with a smoker, had secondary exposure at home, and had at least 1 hour of TSE were significantly more likely than were unexposed peers to report shortness of breath, difficulty exercising, wheezing during and after exercise, and a dry cough at night (P less than .001).

The researchers also assessed other health indicators, and found that teens with TSE exposure were significantly less likely than were unexposed peers to report very good or excellent health and were approximately 1.50 times more likely than unexposed peers to report missing school because of poor health.

The results were limited by several factors including the use of self-reports of TSE and parent reports of emergency or urgent care visits, and by the inclusion only of other public use variables in the PATH database, the researchers noted. But they adjusted for potentially confounding factors such as household income level, parent education, and health insurance status. However, “Because adolescents are high users of EDs and/or [urgent care] for primary care reasons, these venues are high-volume settings that should be used to offer interventions to adolescents with TSE and their families,” they said.

The researchers had no financial conflicts to disclose. The study was funded by the National Institutes of Health via the National Institute on Drug Abuse and the Eunice Kennedy Shriver National Institute of Child Health and Human Development.

When a child presents with hair loss, don’t rule out issues related to genetics and structural abnormalities of the hair itself, according to Maria Hordinsky, MD, of the University of Minnesota, Minneapolis.

The ectodermal dysplasias are a heterogeneous group of disorders in which a main feature is the absent, incomplete, or delayed development of one or more of the appendages derived from ectoderm, such as the hair follicle, Dr. Hordinsky said in a presentation at Skin Disease Education Foundation’s Women’s & Pediatric Dermatology Seminar.

Patients with pure hair and nail ectodermal dysplasia generally present with absent or sparse eyebrows and eyelashes, as well as follicular papules on the scalp and fragile, irregular hair, Dr. Hordinsky said. The condition is caused by a mutation in a gene associated with the production of keratin. In another rare form of hereditary hair loss – hypotrichosis simplex – patients are born with normal hair but lose it gradually from the scalp during the middle of the first decade of life.

The inability to grow long hair characterizes short anagen syndrome, a congenital disorder not to be confused with loose anagen syndrome, Dr. Hordinsky said. Patients with short anagen syndrome experience an idiopathic short anagen phase and as a result, an increased number of hairs in the telogen phase. Children with short anagen syndrome have unusually short hair in early childhood. “Parents typically complain that their children exhibit short hair even though they have never had a haircut,” she explained.

Trichothiodystrophy, a rare autosomal recessive disease, is distinguished by hair that is brittle and sulfur deficient, Dr. Hordinsky said. She cited a review of 112 patients with trichothiodystrophy in which additional distinguishing features included developmental delay/intellectual impairment (86%), short stature (73%), and ichthyosis (65%).

Some cases of hair loss in children have a structural basis, Dr. Hordinsky noted. Structural hair abnormalities include fractures of the hair shaft, extraneous matter on the hair shaft, and hair shaft irregularities such as coiling or twisting, she said.

In trichoptilosis, extensive cuticle loss results in fraying and splitting of the hair shaft, while in patients with trichoclasis, a fractured hair is splinted by a partially intact cuticle.

In trichorrhexis nodosa, the most common type of structural hair abnormality, “intact nodes [of hair] resemble two paintbrushes thrust together,” Dr. Hordinsky explained. Trichorrhexis nodosa may be congenital or acquired, and occurs in children with mental retardation and argininosuccinic aciduria, she said.

A hair shaft abnormality is the culprit behind uncombable hair syndrome, which can be inherited or can occur sporadically, Dr. Hordinsky said. The key feature of the condition is unruly hair caused by a distinctive hair shaft defect, “possibly related to an abnormality in the inner root sheath.” Abnormal hairs usually become apparent at about 3-4 years of age, but eyebrows and eyelashes appear normal. Many patients have a silvery blonde tint to their hair because of how the abnormal hairs reflect light, she said.

When a child presents with hair loss, don’t rule out issues related to genetics and structural abnormalities of the hair itself, according to Maria Hordinsky, MD, of the University of Minnesota, Minneapolis.

Atopic dermatitis is becoming more prevalent in the industrialized world, along with other atopic disorders, including allergic rhinitis and asthma, according to Douglas W. Kress, MD, of the department of dermatology at the University of Pittsburgh.

Recent studies suggest that atopic dermatitis (AD) affects 10%-17% of the U.S. population, and 80%-90% of patients are diagnosed by the age of 5 years, Dr. Kress said in a presentation at Skin Disease Education Foundation’s Women’s & Pediatric Dermatology Seminar.

“There seem to be multiple pathways, which initiate and perpetuate the cutaneous inflammation of AD including exposure to allergens, irritants, and physical trauma, infection, stress, extremes in temperature and humidity,” Dr. Kress said. In addition, foods and airborne allergens may trigger AD.

Many parents may believe that certain factors are associated with AD, but most of these perceptions are not supported by evidence, said Dr. Kress, who is also chief of the division of pediatric dermatology at the Children’s Hospital of Pittsburgh. AD appears to be a disorder of T cell dysregulation dominated by Th2 lesions in acute cases and Th1 inflammation in patients with chronic lesions.

No associations have been proven between the development of AD in the first 18 months of life and any maternal dietary restrictions, according to a recent Cochrane review, nor is there evidence for an association between AD and the introduction of solid foods, exposure to fish oil, or exposure to animals at a young age, he said. In addition, a study published in 2016 showed a lack of evidence to support the use of specific allergen immunotherapy for AD.

However, evidence does support an association between the presence of AD in children and certain other conditions, Dr. Kress said. “Other associations include an increased incidence of alopecia areata, a threefold increase in autism spectrum disorders, and a twofold increase in ADHD in children with atopic dermatitis.”

The only known food allergy linked to AD severity is egg whites; reducing egg white exposure has been shown to improve AD in children with both conditions, he noted.

Although many patients with AD experience annoying but relatively mild symptoms, health care providers should be alert to the potential for infections, particularly with Staphylococcus aureus, and remember that an active egg white allergy has been associated with staphylococcal superantigen sensitization, said Dr. Kress. The increased risk for S. aureus in children with AD may stem from a tendency to underuse antibiotics in AD children, which results in a delayed treatment until the infection becomes overt. In addition, the increased pH in patients with AD might promote the development of pathogenic strains of staph. However, ceramide-based moisturizers could help inhibit these strains by increasing skin acidity.

For patients who have poor AD control with standard therapy, antibiotics may be used as adjunctive therapy. “Consider bleach baths and/or staph decolonization with mupirocin, both of which led to significant improvement in eczema severity compared to placebo,” Dr. Kress said. “Bleach may also have an anti-inflammatory effect.”
