Topical Management of Pediatric Psoriasis: A Review of New Developments and Existing Therapies.

Psoriasis is a chronic immune-mediated disorder that commonly affects adults and children. In recent years, pediatric psoriasis has increased in prevalence and the disease is often associated with various comorbidities and psychological distress. The conventional topical treatments for psoriasis, such as corticosteroids, calcineurin inhibitors, vitamin D analogs, anthralin, and coal tar, are often limited by their side effects, tolerability, and/or efficacy, particularly for use in children and on sensitive and intertriginous areas. Recently, the US Food and Drug Administration approved two new topical non-steroidal agents for treating psoriasis that target different pathogenic pathways than the conventional treatments. Roflumilast is a phosphodiesterase type 4 inhibitor approved for the treatment of plaque psoriasis in patients aged 12 years and older. Tapinarof is a novel aryl hydrocarbon receptor modulator approved for adult psoriasis and currently undergoing studies for pediatric psoriasis. Ongoing efforts are also being made to optimize conventional treatments, for instance, a new foam formulation of halobetasol propionate was recently approved for pediatric psoriasis. Clinical trials of various new drugs targeting one or multiple pathogenic pathways of psoriasis, such as Janus kinase inhibitors, different formulations of phosphodiesterase type 4 inhibitors, and aryl hydrocarbon receptor modulators have also been explored. The recent emergence of novel topical agents provides promising new options for managing pediatric psoriasis with the potential to improve clinical outcomes and quality of life. In this article, we review the mechanism of action, efficacy, and safety profile of novel topical agents and discuss their potential roles in the management of pediatric psoriasis.

Congenital syphilis presenting with granulomatous scalp nodules.

We describe a case of congenital syphilis in an adopted infant with a unique dermatologic presentation of scalp granulomas, along with lymphadenopathy, anemia, and elevated liver transaminases. To our knowledge, this cutaneous morphology has not been previously reported in the literature. This case highlights the varied clinical presentation of congenital syphilis and the diagnostic challenge it poses for clinicians, especially in the context of unknown prenatal history/unknown risk factors, or if syphilis is acquired during pregnancy after routine screening is performed. As the incidence of congenital syphilis has more than tripled in recent years, this diagnosis should be considered when a neonate or infant presents with unexplained skin nodules.

Lower socioeconomic status is associated with delayed access to care for infantile hemangioma: A cohort study.

BACKGROUND: Early specialist evaluation during rapid proliferative growth of complicated infantile hemangiomas (IHs) is crucial. Health disparities and barriers of access to care for children with IHs have not been examined. OBJECTIVE: To investigate whether socioeconomic status (SES) is associated with age at presentation to a subspecialist for IH evaluation. METHOD: A retrospective cohort study of 804 children presenting to a large academic hospital. The primary outcome was age at initial presentation. Covariates included demographic, socioeconomic, geographic, and clinical characteristics. Medicaid and the Children's Health Insurance Program were proxies for lower SES. Analysis of covariance, chi-square tests, and generalized ordered logistic regressions were performed. RESULTS: Children with lower SES had higher odds of presenting after 3 months of age (odds ratio, 2.11; 95% confidence interval, 1.31-3.38). In the subset that qualified for the institutional care management program (ICMP), no risk factors were associated with delayed presentation. LIMITATIONS: Use of insurance and economic distress as proxies for SES; exclusion of uninsured children, which may have resulted in underestimation of racioethnic effects; and examination of a single academic center, which may limit generalizability. CONCLUSIONS: Children with IHs and lower SES were more likely to present later to specialists, but those enrolled in an ICMP were not, suggesting that integrated ICMPs may mitigate disparities and delayed access to care for IHs among lower-SES populations.

Topical timolol as adjunct therapy to shorten oral propranolol therapy for infantile hemangiomas.

BACKGROUND/OBJECTIVES: First-line therapy for infantile hemangiomas (IH) is oral propranolol, a systemic beta-blocker with the risk of rare but serious adverse effects. Topical timolol presents an attractive off-label alternative with good tolerability, but sequential therapy with propranolol followed by timolol is not well studied. Here, we report effects of topical timolol preceding or following oral propranolol as adjunct therapy for IH. METHODS: A retrospective chart review of 559 patients with IH seen at the pediatric dermatology clinic of a tertiary care center between December 2008 and January 2018. Children were grouped by treatment received: propranolol only, timolol only, propranolol to timolol, timolol to propranolol to timolol, and timolol to propranolol. Patient demographics, clinical/treatment characteristics, and pairwise differences were explored between groups. RESULTS: Among all patients treated with propranolol, those who received propranolol followed by timolol received the shortest duration of oral propranolol and were the youngest at the time of propranolol completion. These patients received propranolol for a median of 2.2 months duration (P = 0.006) and were a median of 1.7 months younger (P = 0.007) compared with patients who received oral propranolol only. None had treatment failure defined as requiring propranolol reinitiation, compared with 13% of patients in the propranolol only group (P = 0.036). CONCLUSIONS: Sequential therapy with oral propranolol followed by topical timolol for IH may help minimize potential adverse effects of systemic beta-blockers by reducing the duration of propranolol therapy and facilitating successful taper at a younger age without an increase in treatment failures.

Adult autoimmune enteropathy presenting initially with acquired Acrodermatitis Enteropathica: a case report.

BACKGROUND: Acrodermatitis enteropathica (AE) is a rare dermatitis secondary to zinc deficiency most commonly seen as an inherited disease in infants. In the last decade, increased number of reports have been published on the acquired form that presents in adulthood. Unlike its inherited counterpart, acquired AE (AAE) is often secondary to underlying pathologic or iatrogenic etiologies that interfere with nutritional absorption, such as inflammatory bowel disease or alcoholism. Various gastrointestinal pathologies have been associated with AAE, but there is currently no report on its association with adult autoimmune enteropathy (AIE), a rare gastrointestinal disorder commonly seen in infants, with limited cases reported in adults. Here we present a case in which AAE was the initial clinical manifestation in an adult patient subsequently diagnosed with AIE. CASE PRESENTATION: A 41-year-old African American female presented to our emergency department at the Johns Hopkins Hospital with several months of progressively worsening dermatitis in the legs and acral regions, along with worsening symptoms of diarrhea, alopecia, poor oral intake, lethargy, hematochezia, peripheral edema, and weight loss. Our dermatology team was consulted given a presentation of exquisitely tender, erythematous, and diffusely desquamating skin lesions in the setting of two prior outside hospitalizations in the last 3 months with the same dermatitis that was refractory to topical and oral corticosteroids. Low serum zinc level and positive response to zinc supplementation confirmed the diagnosis of AAE. However, persistent hypovitaminosis and mineral deficiency despite aggressive nutritional supplementation prompted further investigation for an underlying malabsorption etiology. Jejunal biopsy and associated autoantibodies confirmed a diagnosis of adult AIE. CONCLUSION: This case highlights the fact that adult AIE can present initially with clinical findings of AE. While proper zinc supplementation can resolve the latter, recognizing this association can trigger earlier diagnosis, minimize unnecessary tests, and establish earlier intervention to improve quality of life and prevent recurrence of AAE. The case also highlights the importance of collaboration between general and subspecialist physicians in identifying a primary etiology to a secondary clinical presentation. This report can be beneficial to general internists and emergency physicians, as much as it can be to dermatologists, rheumatologists, and gastroenterologists.

Development of global health education at Johns Hopkins University School of Medicine: a student-driven initiative.

Global health is increasingly present in the formal educational curricula of medical schools across North America. In 2008, students at Johns Hopkins University School of Medicine (JHUSOM) perceived a lack of structured global health education in the existing curriculum and began working with the administration to enhance global health learning opportunities, particularly in resource-poor settings. Key events in the development of global health education have included the introduction of a global health intersession mandatory for all first-year students; required pre-departure ethics training for students before all international electives; and the development of a clinical global health elective (Global Health Leadership Program, GHLP). The main challenges to improving global health education for medical students have included securing funding, obtaining institutional support, and developing an interprofessional program that benefits from the resources of the Schools of Medicine, Public Health, and Nursing. Strategies used included objectively demonstrating the need for and barriers to more structured global health experiences; obtaining guidance and modifying existing resources from other institutions and relevant educational websites; and harnessing institution-specific strengths including the large Johns Hopkins global research footprint and existing interprofessional collaborations across the three schools. The Johns Hopkins experience demonstrates that with a supportive administration, students can play an important and effective role in improving global health educational opportunities. The strategies we used may be informative for other students and educators looking to implement global health programs at their own institutions.

Resource utilization of pediatric patients exposed to venom.

BACKGROUND AND OBJECTIVE: Treating envenomation with antivenom is costly. Many patients being treated with antivenom are in observation status, a billing designation for patients considered to need care that is less resource-intensive, and less expensive, than inpatient care. Observation status is also associated with lower hospital reimbursements and higher patient cost-sharing. The goal of this study was to examine resource utilization for treatment of envenomation under observation and inpatient status, and to compare patients in observation status receiving antivenom with all other patients in observation status. METHODS: This was a retrospective study of patients with a primary diagnosis of toxic effect of venom seen during 2009 at 33 freestanding children's hospitals in the Pediatric Health Information System. Data on age, length of stay, adjusted costs (ratio cost to charges), ICU flags, and antivenom utilization were collected. Comparisons were conducted according to admission status (emergency department only, observation status, and inpatient status), and between patients in observation status receiving antivenom and patients in observation status with other diagnoses. RESULTS: A total of 2755 patients had a primary diagnosis of toxic effect of venom. Of the 335 hospitalized, either under observation (n = 124) or inpatient (n = 211) status, 107 (31.9%) received antivenom. Of those hospitalized patients receiving antivenom, 24 (22.4%) were designated as observation status. Costs were substantially higher for patients who received antivenom and were driven by pharmacy costs (mean cost: $17 665 for observation status, $20 503 for inpatient status). Mean costs for the 47 162 patients in observation status with other diagnoses were $3001 compared with $17 665 for observation-status patients who received antivenom. CONCLUSIONS: Treatment of envenomation with antivenom represents a high-cost outlier within observation-status hospitalizations. Observation status can have financial consequences for hospitals and patients.
