TOPLINE:

Combined pediatric dermatology-rheumatology clinics can improve patient care and patient satisfaction, a survey of dermatologists suggested.

METHODOLOGY:

• Combined pediatric dermatology-rheumatology clinics can improve patient outcomes and experiences, particularly for pediatric autoimmune conditions presenting with both cutaneous and systemic manifestations.
• The researchers surveyed 208 pediatric dermatologists working in combined pediatric dermatology-rheumatology clinics.
• A total of 13 member responses were recorded from three countries: 10 from the United States, two from Mexico, and one from Canada.

TAKEAWAY:

• Perceived benefits of combined clinics were improved patient care through coordinated treatment decisions and timely communication between providers.
• Patient satisfaction was favorable, and patients and families endorsed the combined clinic approach.
• Barriers to clinic establishment included differences in the pace between dermatology and rheumatology clinic flow, the need to generate more relative value units, resistance from colleagues, and limited time.
• Areas that needed improvement included more time for patient visits, dedicated research assistants, new patient referrals, additional patient rooms, resources for research, and patient care infrastructure.

IN PRACTICE:

The insights from this survey “will hopefully inspire further development of these combined clinics,” the authors wrote.

SOURCE:

The investigation, led by Olga S. Cherepakhin, BS, University of Washington, Seattle, Washington, was published in Pediatric Dermatology.

LIMITATIONS:

Limitations included the subjective nature, lack of some information, selection bias, and small number of respondents, and the survey reflected the perspective of the pediatric dermatologists only.

DISCLOSURES:

The study was supported by the National Center for Advancing Translational Sciences of the National Institutes of Health. One author reported full-time employment at Janssen R&D, and the other authors had no disclosures.

TOPLINE:

The Injury Prevention Program (TIPP), supported by pediatric residents and equipped with parent-focused tools, effectively reduced reported childhood injuries over the first 2 years of life.

METHODOLOGY:

• The American Academy of Pediatrics designed TIPP in 1983 to aid pediatricians in preventing unintentional injuries among children. TIPP’s effectiveness in reducing childhood injuries had not been formally evaluated in a randomized trial prior to this study.
• TIPP implementation included developmentally based safety counseling and distribution of age-appropriate safety materials to parents.
• A total of 781 parent-infant dyads participated, with the study population primarily consisting of low-income, Hispanic, and non-Hispanic Black families.
• Parent-reported injuries were tracked at each well-child check from 2 to 24 months, with the study adjusting for baseline child, parent, and household factors.

TAKEAWAY:

• TIPP led to a significant reduction in reported childhood injuries over 2 years with adjusted odds ratios of 0.77 (0.66-0.91), 0.60 (0.44-0.82), 0.32 (0.16-0.62), 0.26 (0.12-0.53), and 0.27 (0.14-0.52) at 4, 6, 12, 18, and 24 months, respectively.
• The study highlights the need for further research to explore TIPP’s impact on serious injuries and to identify optimal implementation strategies in busy clinical settings.
• IN PRACTICE:

“This program includes a developmentally based safety counseling schedule that guides what materials (safety sheets and an age-appropriate Framingham safety survey) to ask about risk behaviors. For the age group relevant here, there are pediatric patient handouts for parents of children who are aged 0 to 6 months, 6 to 12 months, and 1 to 2 years, and they review safety for falls, motor vehicles, firearms, drowning, poisoning, choking, and burns”, wrote the authors of the study.

SOURCE:

The study was led by Eliana M. Perrin, MD, MPH, Department of Pediatrics, Johns Hopkins University Schools of Medicine and Nursing, Baltimore, Maryland. It was published online in Pediatrics.

LIMITATIONS:

Further research is necessary to assess TIPP’s effect on serious injuries and to determine effective implementation strategies in various clinical settings.

DISCLOSURES:

The study was supported by grants from the Eunice Kennedy Shriver Institute of Child Health and Development, with supplemental funding from the Centers for Disease Control and Prevention, and the Office of Behavioral and Social Sciences Research.

TOPLINE:

In patients with polycystic ovary syndrome (PCOS), laser and light therapies, alone or in combination with pharmacological agents, improve hirsutism and psychological well-being in women, according to the results of a systematic review.

METHODOLOGY:

• Hirsutism, which affects 70%-80% of women with PCOS, is frequently marginalized as a cosmetic issue by healthcare providers, despite its significant psychological repercussions, including diminished self-esteem, reduced quality of life, and heightened depression.
• The 2023 international evidence-based PCOS guideline considers managing hirsutism a priority in women with PCOS.
• Researchers reviewed six studies (four randomized controlled trials and two cohort studies), which included 423 patients with PCOS who underwent laser or light-based hair reduction therapies, published through 2022.
• The studies evaluated the alexandrite laser, diode laser, and intense pulsed light (IPL) therapy, with and without pharmacological treatments. The main outcomes were hirsutism severity, psychological outcome, and adverse events.

TAKEAWAY:

• Alexandrite laser (wavelength, 755 nm) showed effective hair reduction and improved patient satisfaction (one study); high-fluence treatment yielded better outcomes than low-fluence treatment (one study). Alexandrite laser 755 nm also showed longer hair-free intervals and greater hair reduction than IPL therapy at 650-1000 nm (one study).
• Combined IPL (600 nm) and metformin therapy improved hirsutism and hair count reduction compared with IPL alone, but with more side effects (one study).
• Diode laser treatments (810 nm) with combined oral contraceptives improved hirsutism and related quality of life measures compared with diode laser alone or with metformin (one study).
• Comparing two diode lasers (wavelengths, 810 nm), low-fluence, high repetition laser showed superior hair width reduction and lower pain scores than high fluence, low-repetition laser (one study).

IN PRACTICE:

Laser and light treatments alone or combined with other treatments have demonstrated “encouraging results in reducing hirsutism severity, enhancing psychological well-being, and improving overall quality of life for affected individuals,” the authors wrote, noting that additional high-quality trials evaluating these treatments, which include more patients with different skin tones, are needed.

SOURCE:

The first author of the review is Katrina Tan, MD, Monash Health, Department of Dermatology, Melbourne, Victoria, Australia, and it was published online in JAMA Dermatology.

LIMITATIONS:

Limitations include low certainty of evidence because of the observational nature of some of the studies, the small number of studies, and underrepresentation of darker skin types, limiting generalizability.

DISCLOSURES:

The review is part of an update to the PCOS guideline, which was funded by the Australian National Health and Medical Research Council through various organizations. Several authors reported receiving grants and personal fees outside this work. Dr. Tan was a member of the 2023 PCOS guideline evidence team. Other authors declared no conflicts of interest.

DENVER — Lidocaine injections into the greater occipital nerve relieve severe, refractory migraine attacks in children, results of a randomized controlled trial show. 

Investigators found children receiving bilateral occipital nerve blocks with 2% lidocaine had significantly greater pain relief than that of peers receiving saline injections. 

Cases series have shown a benefit of peripheral nerve blocks (PNBs) — injections of local anesthetics over branches of the occipital or trigeminal nerve — for severe, refractory headache in children.  

Although 80% of pediatric headache specialists use PNBs, there is “inconsistent insurance coverage” for this treatment, which had not been tested in a randomized controlled trial in children before now, lead investigator Christina Szperka, MD, with the Pediatric Headache Program, Department of Neurology, University of Pennsylvania Perelman School of Medicine, Philadelphia, told delegates attending the 2024 annual meeting of the American Academy of Neurology. 
 

Significant Results

Investigators enrolled 58 children and adolescents with acute status migrainosus. The mean age was 16 years, and reported gender was female for 44 participants, male for 11 participants, and nonbinary or transgender in 3 participants. Participants had a migraine flare duration of 22 days and had not responded to other treatments. 

All participants had topical lidocaine cream applied for 30 minutes as a run-in step and could decline injections if they experienced sufficient benefit from cream alone. 

“We used a lidocaine cream lead-in for two reasons. One was to try to see if we could address the issue of high placebo response in pediatric trials in particular, and also to see if we could help with blinding to injection,” said Dr. Szperka. 

Topical lidocaine cream led to a small decrease in pain score overall (0.2 point on a 0-10 scale), and all participants proceeded to randomized blinded bilateral greater occipital nerve injection with 2% lidocaine or saline, she reported. 

On the primary endpoint — change in pain score at 30 minutes — lidocaine was significantly more effective than saline, achieving a 2.3-point decrease on average (on a 0-10 scale) vs a 1.1-point decrease with saline (P = .01).

A 2-point pain reduction was achieved in 69% of patients in the lidocaine group versus 34% in the saline group.

Three quarters (76%) of patients getting lidocaine reported at least partial relief in severity or location of pain compared with 48% of those getting saline (P = .03). Rates of pain freedom at 30 minutes were 17% and 7%, respectively, and at 24 hours were 14% and 0%, respectively.

The majority of adverse events were mild and fairly equal across groups and included anxiety, worsening headache, injection site pain, dizziness, and numbness (more so with lidocaine). There was one case of anaphylaxis after lidocaine injection.

Quite unexpectedly, said Dr. Szperka, patients rated the saline injection as more painful than the lidocaine injection. “This was not what I expected going in, and I think is relevant for future trials,” she said.
 

Encouraging Results 

Reached for comment, Shaheen Lakhan, MD, a neurologist and researcher based in Miami, said that as a neurologist and pain physician, he sees firsthand the “devastating impact of status migrainosus on children.”

“These debilitating headaches can rob them of precious school days, hindering learning and social interaction,” said Dr. Lakhan. “The constant pain and fear of the next attack can also take a toll on their emotional well-being.”

The impact on families is significant as well, highlighting the need to find more effective treatments, Dr. Lakhan said. 

“Traditionally, we’ve relied on case studies to see the benefits of nerve blocks for migraine in younger patients. This is the first randomized controlled trial that shows lidocaine injections can be significantly more effective than a placebo for these unrelenting migraines,” he said.

“It’s important to note that this is a relatively small study, and not without safety concerns, including rare but potentially life-threatening anaphylaxis to lidocaine,” Dr. Lakhan added. “More research is needed, but these findings are encouraging. Lidocaine injections could become a valuable tool for managing treatment-resistant migraines in adolescents and young adults.”

The study was supported by a grant from the National Institute of Neurological Disorders and Stroke. Dr. Szperka is a consultant for AbbVie and Teva; serves on a Data Safety Monitoring Board for Eli Lilly and Upsher-Smith; and is a site principal investigator for AbbVie, Amgen, Biohaven/Pfizer, Teva, and Theranica. Dr. Lakhan had no disclosures.

Reached for comment, Shaheen Lakhan, MD, a neurologist and researcher based in Miami, said that as a neurologist and pain physician, he sees firsthand the “devastating impact of status migrainosus on children.”

“These debilitating headaches can rob them of precious school days, hindering learning and social interaction,” said Dr. Lakhan. “The constant pain and fear of the next attack can also take a toll on their emotional well-being.”

The impact on families is significant as well, highlighting the need to find more effective treatments, Dr. Lakhan said. 

“Traditionally, we’ve relied on case studies to see the benefits of nerve blocks for migraine in younger patients. This is the first randomized controlled trial that shows lidocaine injections can be significantly more effective than a placebo for these unrelenting migraines,” he said.

“It’s important to note that this is a relatively small study, and not without safety concerns, including rare but potentially life-threatening anaphylaxis to lidocaine,” Dr. Lakhan added. “More research is needed, but these findings are encouraging. Lidocaine injections could become a valuable tool for managing treatment-resistant migraines in adolescents and young adults.”

The study was supported by a grant from the National Institute of Neurological Disorders and Stroke. Dr. Szperka is a consultant for AbbVie and Teva; serves on a Data Safety Monitoring Board for Eli Lilly and Upsher-Smith; and is a site principal investigator for AbbVie, Amgen, Biohaven/Pfizer, Teva, and Theranica. Dr. Lakhan had no disclosures.

SAN DIEGO — Whether you completed your dermatology residency training 20 years ago or 2 years ago, recent advances in treatments for atopic dermatitis (AD) have likely influenced your “go to” interventions when treating children with AD, according to Lawrence F. Eichenfield, MD.

“There have been many changes in the understanding of AD and recognition of the variable courses of the disease, and the associated allergic and nonallergic comorbidities,” Dr. Eichenfield, chief of pediatric and adolescent dermatology at Rady Children’s Hospital-San Diego in California, said at the Society for Pediatric Dermatology meeting, held the day before the annual meeting of the American Academy of Dermatology. “With our revolutionary systemic and evolving topical therapies, we are in a new day of pediatric management.”

Drawing from 2023 American Academy of Dermatology guidelines of care on topical treatments of AD and his own clinical experience, he shared his perspective on “what’s tried and true” in care for patients with persistent eczema:

Both bathing and moisturizing leave skin moist. It’s well established that the use of moisturizers/emollients minimizes xerosis and the amount of prescription anti-inflammatory medications, but limited evidence exists to recommend a particular ingredient and formulation, said Dr. Eichenfield, also professor of dermatology and pediatrics at the University of California, San Diego. “Future studies may tell us whether specific moisturizers work better than others, and/or if early interventions may prevent AD, but that remains a big question mark,” he noted. In addition, applications may sometimes “mobilize” topical prescriptive residual absorption and activity.

As for baths, he said, “avoidance of bathing to avoid drying out skin is a practice without evidence basis. Bathing also may have many benefits in active eczema.”

Bleach baths may enhance skin barrier function, reduce itch, and improve eczema, but the practice remains controversial, he continued. Authors of a systematic review and meta-analysis concluded that while bleach baths are effective in reducing the severity of AD, they do not appear to be more effective than water bath alone. Authors of a more recent study found that bleach baths did not normalize dysbiosis, “but that study did not compare outcomes to bathing without bleach,” Dr. Eichenfield noted.“My sense is there is some benefit to regular bathing, especially in children with moderate to severe AD, especially those with colonized or infected eczema.”

He advises clinicians to be aware of other “standard AD interventions” from around the world, including black tea wet dressings and green tea bath therapy.

Topical corticosteroids. These are “tried and true” for their anti-inflammatory properties and rapid response, relatively low cost, and large range of potency, he said. Potential problems include the burden of topical application and the potential for stinging/burning, atrophy, telangiectasias, adrenal axis suppression, and concerns about withdrawal phenomena. “Being a proponent of topical corticosteroids, but explaining reasonable and appropriate use can be challenging,” Dr. Eichenfield said. “Social media has influenced concerns about topical corticosteroids, with steroid addiction and withdrawal being concerns influencing discomfort with therapies.”

Make sure to measure outcomes. The suggested core outcome measure for recording clinical signs in AD clinical trials is the Eczema Area and Severity Index (EASI) score, he said. In clinical practice, Dr. Eichenfield favors body surface area (BSA) and the Validated Global Assessment scale (v-IGA) to measure signs of moderate to severe AD. “Documenting extent of disease makes a big difference in families understanding how severe their child’s disease is and how it is doing over time.” Alternatively, he recommends the Atopic Dermatitis Control Tool (ADCT) or the Recap of Atopic Eczema (RECAP) as tools assessing long-term disease control.

Familiarize yourself with nonsteroidal anti-inflammatory medications for care regimens. Options include topical calcineurin inhibitors (TCIs) such as tacrolimus and pimecrolimus; phosphodiesterase 4 (PDE-4) inhibitors such as crisaborole and roflumilast; the aryl-hydrocarbon receptor agonist tapinarof; and topical Janus kinase (JAK) inhibitors such as delgocitinib and ruxolitinib as well as others in development. “There is variable status around the world in terms of whether these nonsteroidal options are approved or not,” Dr. Eichenfield said. “Issues of use include cost, availability, side effects, and concerns about potential absorption. I think there’s an evolution in how much we rely on these instead of topical corticosteroids. They’re more commonly used in maintenance regimens rather than for remission induction.”

Dr. Eichenfield encouraged dermatologists to share information about and experiences with evolving treatment options for AD, “because when the studies are done, they are done as monotherapy. We must translate that into clinical practice and figure out how they fit in. Our exchange of information is critical.”

Dr. Eichenfield disclosed conflicts of interest from many pharmaceutical companies, including those with AD treatments.

TOPLINE:

Infants with port-wine birthmarks (PWB) achieved near-total or total clearance with weekly pulsed dye laser (PDL) treatments in a case-series of 10 infants.

METHODOLOGY:

• Early intervention of PWB in infants can significantly improve outcomes, and some studies suggest shorter intervals between laser treatments may be more effective. While laser treatment with PDL is the gold standard, the optimal treatment interval has not been determined.
• Researchers evaluated the records of 10 infants with PWB who received weekly PDL treatments from 2022 to 2023 at a single center. Treatment was initiated when the infants were 6 months old or younger, with the median age at the first treatment being 4 weeks. Of the 10 infants, eight had Fitzpatrick skin types I-III and two had skin type IV.
• Two dermatologists assessed photographs taken before and after laser treatment, and the primary outcome was the percentage improvement of PWB.

TAKEAWAY:

• Of the 10 patients, six achieved near-total (76%-95%) clearance, and one achieved total (96%-100%) clearance of PWB at a mean of 2 months after the first treatment.
• Marked improvement (51%-75%) in PWB was observed in the remaining three patients, who achieved near-total clearance with additional treatments.
• The median duration of treatment was 2 months (range, 0.2-5.1), and a median of eight treatments (range, 2-20) were needed to achieve near total or total clearance.
• No adverse events were reported, including pigmentary changes, scarring, burns, erosions, or infections.

IN PRACTICE:

The outcomes in the case series, the authors concluded, “are compelling and warrant attention and further investigation into the possibility that this novel and decreased treatment interval of 1 week ... is associated with potential improvement in outcomes and shorter overall treatment duration.”

SOURCE:

This study was led by Shirin Bajaj, MD, of the Laser & Skin Surgery Center of New York, where the infants were treated, and was published online on April 17, 2024, in JAMA Dermatology.

LIMITATIONS:

A small sample size and the lack of a comparison arm limited the ability to draw any conclusions or make treatment recommendations based on the results.

DISCLOSURES:

The authors disclosed no conflicts of interest.

The current tetravalent dengue vaccine TAK-003, from the Japanese laboratory Takeda, is not likely to control the ongoing epidemic, according to the Pan American Health Organization (PAHO). The organization emphasized the need to better understand the vaccine’s effectiveness against different serotypes and its safety under real-world clinical conditions.

The Americas are experiencing a record increase in dengue cases. Three times as many cases have been identified during 2024 (3.5 million) than were reported for the same period in 2023. 

“The vaccine we have available will not curb the dengue epidemic; it should be used complementarily with other actions. The most important actions are field operations, vector control, prevention, and education,” said Daniel Salas, MD, executive manager of the PAHO Comprehensive Immunization Program, during a press conference on March 28.

“The vaccines we currently have are not the best response to reduce transmission and prevent deaths,” added Jarbas Barbosa, MD, PhD, PAHO’s director. The fatality rate remains below 0.05%, but this figure could be hard to maintain if the situation becomes more uncontrolled.

The TAK-003 regimen consists of two doses with a 3-month interval between applications, so “it is not a tool to control transmission at this moment. Studies have shown that only 8 years of [population-level] vaccination would have a significant impact on dengue transmission,” said Dr. Barbosa.

A new vaccine developed in Brazil in partnership with the company MSD, Butantan-DV, is in phase 3 trials and has the advantage of being a single-dose application, which could facilitate its use in situations with accelerated transmission. “But this vaccine will likely only be available in 2025,” said Dr. Barbosa.

PAHO officials also highlighted the need to better characterize the vaccine’s effectiveness and safety in the real world. They observed, for example, that when TAK-003 was investigated, the circulation of dengue serotype 3 was almost nonexistent, so the efficacy data against that serotype “are very limited.”

“The producer, Takeda, has very limited production capacity. Brazil is the country that uses this vaccine the most, followed by Argentina. Given that these countries have a good epidemiological surveillance system and adverse effect registration, they can conduct studies on how the vaccine performs in real life, which will greatly increase our knowledge about it. For example, we will see its effectiveness against serotype 3,” said Dr. Barbosa.

The PAHO Technical Advisory Group (TAG) on vaccine-preventable diseases recommended that any country using these vaccines have surveillance systems in place because it is important to promptly report and investigate any adverse events, said Dr. Salas. The organization also suggested that vaccination should ideally be administered in a “more controlled environment,” a phase 4 study, “to complete the safety and efficacy profile, especially in those who have not had dengue before and for dengue 3 and 4,” said Dr. Salas in response to a question from this news organization.

“People cannot expect that just because they were vaccinated, they will not get dengue. The vaccine has limited reach,” he emphasized.

Other research strategies for vector control, such as the use of the Wolbachia bacteria and mosquito sterilization, are future strategies and “not tools to control this outbreak,” noted Sylvain Aldighieri, MD, director of the Department of Prevention, Control, and Elimination of Transmissible Diseases at PAHO.

In his opening remarks, Dr. Barbosa urged the intensification of efforts with tools that are already available. These approaches include eliminating mosquito breeding sites (“80% are in or near homes”) and protecting against mosquito bites, preparing health services for early diagnosis and timely clinical management, and educating the population about dengue symptoms so they seek medical attention immediately.

Although dengue is increasing throughout Latin America and the Caribbean, the most affected countries are Brazil (83%), Paraguay (5.3%), and Argentina (3.7%), which account for 92% of the cases and 87% of the deaths, PAHO reported.

DENVER — Intravenous (IV) ketamine is an effective and safe treatment option for children with severe refractory headache, new research suggests. In a retrospective chart review, IV ketamine led to in a 50% reduction in pain at discharge, with “nearly two-thirds” of patients having no recurrence within 30 days, noted lead investigator Scott Rosenthal, MD, from the University of Colorado Anschutz Medical Campus, Aurora.

Dr. Rosenthal reported the findings at the 2024 annual meeting of the American Academy of Neurology.
 

Statistically Significant Pain Relief

“IV ketamine has shown benefit in nonheadache chronic pain syndromes and refractory mood disorders. Patients with refractory status migraines are often left with ongoing pain and dysfunction after failing typical interventions,” Dr. Rosenthal said. 

“Ketamine has emerged as a potential treatment option in this population. However, there’s very little research on the efficacy and tolerability of it in general as well as the pediatric population,” he noted. 

Dr. Rosenthal and colleagues took a look back at patients admitted to Children’s Hospital Colorado between 2019 and 2022 for treatment of severe refractory headache who were treated with continuous IV ketamine. 

They analyzed 68 encounters of 41 unique patients aged 5-21 years (median age 16 years; 85% girls). Chronic migraine without aura made up 79% of cases. 

On presentation, most patients had an exacerbation or ongoing worsening of pain for about 10 days, and all but two were taking a preventive medication. Nearly 70% had a comorbid psychiatric diagnosis such as anxiety or depression, and 60% had a comorbid chronic pain diagnosis separate from their headache diagnosis. 

The primary outcome was percent pain reduction at discharge and headache recurrence within 72 hours, with headache recurrence defined as receipt of neurology care via phone, clinic, or hospital encounter. 

Patients received IV ketamine at a median dose of 0.25 mg/kg/hr for a median of 3 days.

Overall, the treatment was “safe and well tolerated,” Dr. Rosenthal said. 

There were no serious adverse events and no cardiac side effects; 7% (five out of 68) stopped treatment due to side effects. The most common side effects were dizziness (23%), nausea (16%), blurred vision (12%), hallucinations (19%), cognitive fog (7%), vomiting (6%) and dysphoria (4%), worsening headache (4%), and paresthesia and cramping (1.5%).
 

‘Exciting Starting Point’

At baseline, pain scores were 8 (on a scale of 0-10) and progressively fell (improved) during treatment. Pain scores were 6 on day 1 and were 5 on day 2, with a slight rebound to 5 at discharge, although the pain reduction at discharge (vs baseline) remained statistically significant (P < .001). 

“The median percent pain reduction after 3 days of ketamine was about 40%,” Dr. Rosenthal said. 

He noted that on the first day of treatment, 16% of patients responded to treatment (with a > 50% reduction in their initial pain); this doubled to 33% on day 2 and increased to 44% at discharge. 

In terms of recurrence, 38% had a recurrence within 1 month, “meaning two thirds did not,” Dr. Rosenthal noted. Median time to recurrence was 7 days. There were no recurrences within 72 hours. 

The researchers also tried to tease out which patients might respond best to ketamine.

“Surprisingly,” there wasn’t a strong effect of most demographic variables such as age, sex, gender identity, chronic pain, psychiatric comorbidities, duration of headache, or prior interventions, Dr. Rosenthal noted. 

“Interestingly,” he said, patients who were on two or more preventive medications had a 50% reduction in their pain at discharge compared with a 33% reduction in patients taking one or no preventive medication. It’s possible that more preventative medications may “prime” a patient’s response to ketamine, Dr. Rosenthal said. 

She added that future randomized studies are needed to further assess IV ketamine for refractory headache in children, but these results are “an exciting starting point.” 
 

‘Still an Unknown’

Seniha Nur Ozudogru, MD, assistant professor of clinical neurology at Penn Medicine in Philadelphia, echoed the need for further study.

The role of IV ketamine in refractory pediatric headache is “still an unknown,” said Dr. Ozudogru, who was not involved in the study. 

She noted that currently, there is “no standard protocol for ketamine infusion, even for adults. Every institution has their own protocols, which makes it difficult.” 

Dr. Ozudogru also wonders how “doable” in-hospital IV infusions over 3 days may be for children. 

“Especially for chronic migraine patients, it can be really tricky to manage expectations in that even if they don’t respond and the headache doesn’t go away, they still may have to be discharged. That requires a specific approach and discussion with the patients,” Dr. Ozudogru said. 

Intranasal ketamine is another potential option, she said, with a recent study suggesting that intranasal ketamine is an effective treatment for children hospitalized with refractory migraine. 

“However, there is some concern about the potential of addiction and the side effects of hallucinations and what the main protocol will be, so this not a standard treatment and has to be studied further,” she said. 

The study had no specific funding. Dr. Rosenthal and Dr. Ozudogru have no relevant disclosures.

TOPLINE:

Less than 7 hours of sleep per night is common in individuals with type 1 diabetes (T1D) but is tied to poor cardiometabolic health, particularly in adolescents.

METHODOLOGY:

• Sleep is recognized as an important factor in diabetes assessment and treatment by the 2023 American Diabetes Association’s Standards of Medical Care in Diabetes, but it is unclear whether sleep may improve health outcomes across the lifespan in patients with T1D.
• This secondary analysis of the BCQR-T1D crossover trial investigated the link between sleep and cardiometabolic health in 42 adults (age, 19-60 years) and 42 adolescents (age, 12-18 years) with T1D.
• Participants had T1D duration greater than 9 months and received bromocriptine quick-release (BCQR) therapy or placebo for 4 weeks and then switched between the treatments in a separate 4-week period.
• They underwent laboratory testing and anthropometric measurements. Also, continuous glucose monitoring data were collected for a week during each treatment phase along with an accompanying insulin dosing diary.
• Participants were required to wear an actigraphy monitor on the wrist of their nondominant hand for 7 days during each treatment phase to estimate sleep duration.

TAKEAWAY:

• Most adolescents (62%) and adults (74%) with T1D reported less than 7 hours of sleep at baseline.
• Participants with insufficient sleep versus those without insufficient sleep (< 7 vs > 7 hours) had a larger waist circumference and higher mean body mass index, systolic blood pressure, and pulse pressure, as well as lower estimated insulin sensitivity and brachial artery distensibility (P < .05 for all).
• When stratified by age, only adolescents with T1D with insufficient sleep had significant differences in most health outcomes by sleep duration status, except that adults with less than 7 hours of sleep had higher pulse pressure than those with more than 7 hours of sleep.
• Compared with placebo, BCQR slightly improved sleeping parameters in adolescents by delaying their time of waking up and prolonging their time in bed.

IN PRACTICE:

“Sleep may be an important and novel target for improving health in individuals with T1D, particularly when initiated in adolescence or early in diabetes,” the authors wrote.

SOURCE:

Stacey L. Simon, PhD, and Janet K. Snell-Bergeon, PhD, University of Colorado Anschutz Medical Campus, Aurora, led this study, which was published online in Diabetes, Obesity and Metabolism.

LIMITATIONS:

The study lacked polysomnography or melatonin assessment to quantify circadian rhythms and subjective sleep quality ratings. It also had no objective measurement of the timing of the daily pills of BCQR, which, when taken in the morning, are hypothesized to reset the circadian rhythm for hypothalamic dopamine and serotonin. The recommended sleep duration of 8 hours for adolescents was not used as the cutoff value due to too few participants who qualified. Also, this study›s findings may be affected by the fact that participants were recruited throughout the year, while adolescents show different sleeping patterns during the academic year compared with school breaks.

DISCLOSURES:

This work was supported by a JDRF grant. Two authors declared receiving equipment, honoraria for lectures, and support for conference travel, which were all unrelated to this study.

Because of climate change, heat waves, storms, heavy rainfalls, and floods are now occurring in areas that seldom experienced these phenomena before. “Extreme weather events are rare, but in terms of their extent, duration, and scale, they are unusual. And they are increasing due to climate change,” said Andrea Elmer, MD, an internal medicine and pulmonology specialist at the DKD Helios Clinic in Wiesbaden, Germany. She spoke at the Congress of the German Society for Pneumology and Respiratory Medicine.

Dr. Elmer referred to the 2023 status report by the Robert Koch Institute and the 2023 Synthesis Report by the Intergovernmental Panel on Climate Change, in which the likelihood of extreme weather events was acknowledged to be significantly higher than previously recognized. “Knowing about such extreme weather events is important to assess the consequences for our patients and to identify possible medical care needs,” said Dr. Elmer. She focused on the effects of platanus (plane tree) cough and thunderstorm asthma.
 

Platanus Cough

The severe symptoms of 40 students at a comprehensive school in Wiesbaden, including shortness of breath, coughing, and irritated eyes, led to a major operation involving the fire brigade and police on May 11, 2022. The symptoms worsened when the children left the building and waited in the schoolyard. Initially, a chemical attack with irritant gas was suspected because the school is located near an industrial area. There were no indications of a pollen cloud.

Eventually, doctors and firefighters found that the symptoms were caused by platanus cough, which is induced by the fine star-shaped hair found on young platanus leaves, bark, young branches, and buds. If strong winds move the leaves after prolonged dryness, these trichomes can break off when touched, creating platanus dust.

At that time, there were unusual climatic conditions. The temperature was 29 °C, it was dry, and wind gusts reached 50 km/h. The schoolyard was enclosed and densely planted with tall, old plane trees. Initial symptoms occurred in classrooms with open windows.

Twenty-five children had to be admitted to the hospital. Treatment included lorazepam and salbutamol. All students had normal oxygen levels, and the symptoms were reversed.
 

Cough or Allergy?

The clinical differential diagnosis for an allergy is quite simple, said Dr. Elmer. Platanus cough mainly shows symptoms of irritation, a feeling of a foreign body, and scratching in the eyes, throat, and nose. Coughing can also occur. In an allergy, there is often a runny nose and itching in the eyes and nose. Such allergic symptoms do not occur with platanus cough.

It should also be noted that the sensitization rates for a platanus allergy in Germany range between 5% and 11%. “Having so many platanus allergy sufferers in one place was relatively unlikely,” said Dr. Elmer.

She expects an increase in cases of platanus cough, especially in cities with dense construction, such as in narrow schoolyards. High concentrations of platanus dust can occur, especially when it is warm, dry, and windy. “Platanus cough does not occur every time we walk under plane trees. It strongly depends on warmth, dryness, and wind,” said Dr. Elmer.

Patients can protect themselves by avoiding skin and mucous membrane contact under appropriate climatic conditions and by wearing protective glasses and masks. Leaves and branches should not be swept but vacuumed. “Under no circumstances should plane trees be cut down. We need trees, especially in cities,” said Dr. Elmer. Moreover, the trichomes act as biofilters for air pollutants. In critical environments such as schoolyards, seasonal spraying of plane trees with a mixture of apple pectin and water can prevent the star hair from breaking off.
 

Thunderstorm Asthma

For patients with asthma, wildfires, storms, heavy rainfall, and thunderstorms can lead to exacerbations. Emergency room visits and hospital admissions generally increase after extreme weather events.

A study examining the consequences of the fires in California from 2004 to 2009, for example, reported that hospital visits related to asthma increased by 10.3%. Those related to respiratory problems increased by 3.3%. Infants and children up to age 5 years were most affected.

Thunderstorms are increasing because of global warming. Thunderstorm asthma arises under specific meteorological conditions. It typically occurs in patients with aeroallergies (eg, to pollen and fungal spores) in combination with thunderstorms and lightning. Large pollen grains, which normally remain in the upper airways, ascend into higher atmospheric layers and break apart due to updrafts. These very small particles are pushed back to ground level by downdrafts, enter the lower airways, and cause acute asthma.

Worldwide, cases of thunderstorm asthma are rare. About 30 events have been documented. Thunderstorm asthma was first observed in 1983 in Birmingham, England. Fungal spores were the trigger.

The most significant incident so far was a severe thunderstorm on November 21, 2016, in Melbourne, Australia. Worldwide attention was drawn to the storm because of an unusually high number of asthma cases. Within 30 hours, 3365 patients were admitted to emergency rooms. “This is also a high burden for a city with 4.6 million inhabitants,” said Dr. Elmer. Of the patients in Melbourne, 35 were admitted to the intensive care unit and 5 patients died.

Dr. Elmer calculated the corresponding number of patients for Wiesbaden and Mainz. “Assuming a population of 500,000 in this region, that would be 400 patients in emergency rooms within 30 hours, which would be a significant number.”

Such events are mainly observed in Australia, where two events per decade are expected. However, due to climate change, the risk could also increase in Europe, leading to more cases of thunderstorm asthma.
 

Risk Factors

The following environmental factors increase the risk:

• High pollen concentrations in the days before a thunderstorm
• Precipitation and high humidity, thunderstorms, and lightning
• Sudden temperature changes
• Increases in aeroallergen biomass and extreme weather events because of climate change

In Australia, grass pollen was often the trigger for thunderstorm asthma. In the United Kingdom, it was fungal spores. In Italy, olive pollen has a similar potential.

Patients with preexisting asthma, uncontrolled asthma, and high serum-specific immunoglobulin E levels are at risk. The risk is also increased for patients with poor compliance with inhaled steroid (ICS) therapy and for patients who have previously been hospitalized because of their asthma.

Patients with hay fever (ie, seasonal allergic rhinitis) have a significantly higher risk. As Dr. Elmer observed, 88% of patients in the emergency room in Melbourne had seasonal allergic rhinitis. “Fifty-seven percent of the patients in the emergency room did not have previously known asthma, but more than half showed symptoms indicating latent asthma. These patients had latent asthma but had not yet been diagnosed.”

Dr. Elmer emphasized how important it is not to underestimate mild asthma, which should be treated. For patients with hay fever, hyposensitization should be considered.
 

Reducing Risk

Many factors must come together for thunderstorm asthma to develop, according to Dr. Elmer. Because this convergence is difficult to predict, however, preparation and risk reduction are important. They consist of individual precautions and public health strategies.

The following steps can be taken at the individual level:

• Identify risk groups, including patients with allergic rhinitis and high serum-specific immunoglobulin E levels. Patients with hay fever benefit from hyposensitization.
• Avoid outdoor activities on risky days.
• Diagnose asthma, and do not underestimate mild asthma. Improve therapy compliance with ICS therapy and use maintenance and reliever therapy. This way, the patient automatically increases the steroid dose with increased symptoms and is better protected against exacerbations.
• Improve health literacy and understanding of asthma.

Thunderstorm asthma also affects healthcare professionals, Dr. Elmer warned. In Melbourne, 25% of responders themselves showed symptoms. Therefore, expect that some of these clinicians will also be unavailable.

Other steps are appropriate at the public health level. In addition to monitoring local pollen concentrations, one must identify risk groups, especially people working outdoors. “It is very difficult to predict an epidemic of thunderstorm asthma,” said Dr. Elmer. Therefore, it is important to increase awareness of the phenomenon and to develop an early warning system with emergency plans for patients and the healthcare system.

“Allergen immunotherapy is protective,” she added. “This has been well studied, and for Melbourne, it has been demonstrated. Patients with allergic rhinitis who had received immunotherapy were protected. These patients did not have to visit the emergency room. This shows that we can do something, and we should hyposensitize,” Dr. Elmer concluded.

Because of climate change, heat waves, storms, heavy rainfalls, and floods are now occurring in areas that seldom experienced these phenomena before. “Extreme weather events are rare, but in terms of their extent, duration, and scale, they are unusual. And they are increasing due to climate change,” said Andrea Elmer, MD, an internal medicine and pulmonology specialist at the DKD Helios Clinic in Wiesbaden, Germany. She spoke at the Congress of the German Society for Pneumology and Respiratory Medicine.

Dr. Elmer referred to the 2023 status report by the Robert Koch Institute and the 2023 Synthesis Report by the Intergovernmental Panel on Climate Change, in which the likelihood of extreme weather events was acknowledged to be significantly higher than previously recognized. “Knowing about such extreme weather events is important to assess the consequences for our patients and to identify possible medical care needs,” said Dr. Elmer. She focused on the effects of platanus (plane tree) cough and thunderstorm asthma.
 

Platanus Cough

The severe symptoms of 40 students at a comprehensive school in Wiesbaden, including shortness of breath, coughing, and irritated eyes, led to a major operation involving the fire brigade and police on May 11, 2022. The symptoms worsened when the children left the building and waited in the schoolyard. Initially, a chemical attack with irritant gas was suspected because the school is located near an industrial area. There were no indications of a pollen cloud.

Eventually, doctors and firefighters found that the symptoms were caused by platanus cough, which is induced by the fine star-shaped hair found on young platanus leaves, bark, young branches, and buds. If strong winds move the leaves after prolonged dryness, these trichomes can break off when touched, creating platanus dust.

At that time, there were unusual climatic conditions. The temperature was 29 °C, it was dry, and wind gusts reached 50 km/h. The schoolyard was enclosed and densely planted with tall, old plane trees. Initial symptoms occurred in classrooms with open windows.

Twenty-five children had to be admitted to the hospital. Treatment included lorazepam and salbutamol. All students had normal oxygen levels, and the symptoms were reversed.
 

Cough or Allergy?

The clinical differential diagnosis for an allergy is quite simple, said Dr. Elmer. Platanus cough mainly shows symptoms of irritation, a feeling of a foreign body, and scratching in the eyes, throat, and nose. Coughing can also occur. In an allergy, there is often a runny nose and itching in the eyes and nose. Such allergic symptoms do not occur with platanus cough.

It should also be noted that the sensitization rates for a platanus allergy in Germany range between 5% and 11%. “Having so many platanus allergy sufferers in one place was relatively unlikely,” said Dr. Elmer.

She expects an increase in cases of platanus cough, especially in cities with dense construction, such as in narrow schoolyards. High concentrations of platanus dust can occur, especially when it is warm, dry, and windy. “Platanus cough does not occur every time we walk under plane trees. It strongly depends on warmth, dryness, and wind,” said Dr. Elmer.

Patients can protect themselves by avoiding skin and mucous membrane contact under appropriate climatic conditions and by wearing protective glasses and masks. Leaves and branches should not be swept but vacuumed. “Under no circumstances should plane trees be cut down. We need trees, especially in cities,” said Dr. Elmer. Moreover, the trichomes act as biofilters for air pollutants. In critical environments such as schoolyards, seasonal spraying of plane trees with a mixture of apple pectin and water can prevent the star hair from breaking off.
 

Thunderstorm Asthma

For patients with asthma, wildfires, storms, heavy rainfall, and thunderstorms can lead to exacerbations. Emergency room visits and hospital admissions generally increase after extreme weather events.

A study examining the consequences of the fires in California from 2004 to 2009, for example, reported that hospital visits related to asthma increased by 10.3%. Those related to respiratory problems increased by 3.3%. Infants and children up to age 5 years were most affected.

Thunderstorms are increasing because of global warming. Thunderstorm asthma arises under specific meteorological conditions. It typically occurs in patients with aeroallergies (eg, to pollen and fungal spores) in combination with thunderstorms and lightning. Large pollen grains, which normally remain in the upper airways, ascend into higher atmospheric layers and break apart due to updrafts. These very small particles are pushed back to ground level by downdrafts, enter the lower airways, and cause acute asthma.

Worldwide, cases of thunderstorm asthma are rare. About 30 events have been documented. Thunderstorm asthma was first observed in 1983 in Birmingham, England. Fungal spores were the trigger.

The most significant incident so far was a severe thunderstorm on November 21, 2016, in Melbourne, Australia. Worldwide attention was drawn to the storm because of an unusually high number of asthma cases. Within 30 hours, 3365 patients were admitted to emergency rooms. “This is also a high burden for a city with 4.6 million inhabitants,” said Dr. Elmer. Of the patients in Melbourne, 35 were admitted to the intensive care unit and 5 patients died.

Dr. Elmer calculated the corresponding number of patients for Wiesbaden and Mainz. “Assuming a population of 500,000 in this region, that would be 400 patients in emergency rooms within 30 hours, which would be a significant number.”

Such events are mainly observed in Australia, where two events per decade are expected. However, due to climate change, the risk could also increase in Europe, leading to more cases of thunderstorm asthma.
 

Risk Factors

The following environmental factors increase the risk:

• High pollen concentrations in the days before a thunderstorm
• Precipitation and high humidity, thunderstorms, and lightning
• Sudden temperature changes
• Increases in aeroallergen biomass and extreme weather events because of climate change

In Australia, grass pollen was often the trigger for thunderstorm asthma. In the United Kingdom, it was fungal spores. In Italy, olive pollen has a similar potential.

Patients with preexisting asthma, uncontrolled asthma, and high serum-specific immunoglobulin E levels are at risk. The risk is also increased for patients with poor compliance with inhaled steroid (ICS) therapy and for patients who have previously been hospitalized because of their asthma.

Patients with hay fever (ie, seasonal allergic rhinitis) have a significantly higher risk. As Dr. Elmer observed, 88% of patients in the emergency room in Melbourne had seasonal allergic rhinitis. “Fifty-seven percent of the patients in the emergency room did not have previously known asthma, but more than half showed symptoms indicating latent asthma. These patients had latent asthma but had not yet been diagnosed.”

Dr. Elmer emphasized how important it is not to underestimate mild asthma, which should be treated. For patients with hay fever, hyposensitization should be considered.
 

Reducing Risk

Many factors must come together for thunderstorm asthma to develop, according to Dr. Elmer. Because this convergence is difficult to predict, however, preparation and risk reduction are important. They consist of individual precautions and public health strategies.

The following steps can be taken at the individual level:

• Identify risk groups, including patients with allergic rhinitis and high serum-specific immunoglobulin E levels. Patients with hay fever benefit from hyposensitization.
• Avoid outdoor activities on risky days.
• Diagnose asthma, and do not underestimate mild asthma. Improve therapy compliance with ICS therapy and use maintenance and reliever therapy. This way, the patient automatically increases the steroid dose with increased symptoms and is better protected against exacerbations.
• Improve health literacy and understanding of asthma.

Thunderstorm asthma also affects healthcare professionals, Dr. Elmer warned. In Melbourne, 25% of responders themselves showed symptoms. Therefore, expect that some of these clinicians will also be unavailable.

Other steps are appropriate at the public health level. In addition to monitoring local pollen concentrations, one must identify risk groups, especially people working outdoors. “It is very difficult to predict an epidemic of thunderstorm asthma,” said Dr. Elmer. Therefore, it is important to increase awareness of the phenomenon and to develop an early warning system with emergency plans for patients and the healthcare system.
