Background: Onychomycosis is a common nail disease that is often difficult to treat with a high risk of recurrence.

Objective: To update our current understanding of the etiologic profile in pediatric patients with onychomycosis utilizing molecular diagnosis by polymerase chain reaction (PCR) combined with histopathologic examination.

Methods: Records of 19,770 unique pediatric patients were retrieved from a single diagnostic laboratory in the United States spanning over a 9-year period (March 2015 to April 2024). This cohort represents patients clinically suspected of onychomycosis seen by dermatologists and podiatrists. Dermatophytes, nondermatophyte molds (NDMs), and yeasts were identified by multiplex real-time PCR corroborated by the demonstration of fungal invasion on histopathology.

Results: An average of 37.0% of all patients sampled were mycology-confirmed to have onychomycosis. Most patients were between ages 11 and 16 years, and the rate of mycologically confirmed onychomycosis was significantly higher among the 6- to 8-year (47.2%) and 9- to 11-year (42.7%) age groups compared to the 0- to 5-year (33.1%), 12- to 14-year (33.2%), and 15- to 17-year (36.7%) age groups. The majority of infections were caused dermatophytes (74.7%) followed by NDMs (17.4%). The Trichophyton rubrum complex represents the dominant pathogen with higher detection rates in the 6- to 11-year-olds. Fusarium was the most commonly isolated NDM with an increasing prevalence with age.

Conclusions: Elementary school-aged children have a higher risk of contracting onychomycosis which may be attributed to the onset of hyperhidrosis at puberty, use of occlusive footwear, nail unit trauma, and walking barefoot. Fusarium onychomycosis may be more prevalent than expected, and this may merit consideration of management strategies.

Although many clinical variants of Staphylococcus aureus infection are well-recognized, atypical presentations may mimic other conditions. We describe two cases of atypical S. aureus infections in pediatric patients: a S. aureus infection presenting with a vesicopustular rash mimicking varicella zoster virus and a case of multifocal panniculitis. Both of these cases were specifically caused by methicillin-resistant S. aureus (MRSA). Additional cases of atypical S. aureus infections and presenting features from the current literature are also discussed.

Conradi-Hünermann-Happle syndrome is a rare genodermatosis affecting cholesterol metabolism caused by pathogenic variants in the emopamil binding protein (EBP) gene. It presents with skin, skeletal, and ophthalmological alterations. Cutaneous findings include hyperkeratotic lesions following Blaschko lines that subsequently improve leaving scarring alopecia and patches of atrophy. The purpose of this case report is to present a case of a patient treated with simvastatin-cholesterol ointment.

Telomere biology disorders (TBD) are a complex set of inherited illnesses characterized by short telomeres. Dyskeratosis congenita (DC), which is now considered a severe TBD phenotype, is characterized by reticulated pigmentary changes, nail dystrophy, premalignant oral leukoplakia, and systemic involvement. This case describes a 2-year-old female with reticulated pigmentary changes and Terry's nails who was found to have a TERT variant and short telomeres; she lacked other mucocutaneous and systemic features of TBD. This report describes a unique clinical presentation of TBD and highlights the importance of upholding suspicion for TBD in individuals with limited or subtle features of classic DC.

Background: Pre-procedural antisepsis is a critical component of hospital-acquired infection prevention in the neonatal intensive care unit (NICU). However, broadly utilized topical antiseptic agents pose an elevated risk of disruption to neonatal skin integrity, and evidence-based guidelines are lacking. This systematic review of the literature sought to assess and characterize the predisposing risk factors for and types of neonatal skin injury from topical antiseptic agents.

Methods: A systematic search of Medline Ovid, Embase, Web of Science, CINAHL, and Cochrane Library was conducted, including academic literature providing data on neonatal skin injuries related to topical antisepsis in the NICU.

Results: A total of 19 articles (99 patients) met the inclusion criteria. Of the available data, most reported skin injuries were described in extremely preterm (98.1%) and very low birth weight (98.4%) infants. The majority of reported adverse cutaneous events were attributed to chlorhexidine preparations (74.8%), followed by octenidine (18.2%), povidone-iodine (6.1%), and isopropyl alcohol (2.0%). Erythema (40.1%), skin breakdown (23.4%), and chemical burns (17.5%) were the skin reactions reported most frequently, followed by skin irritation (8.3%), and skin necrosis (2.8%).

Conclusions: Our findings indicate that both extremely preterm and very low birth weight infants are particularly susceptible to skin toxicities from pre-procedural antiseptic preparations. These data underscore the need for future research to support the development of guidelines which minimize iatrogenic cutaneous injuries in the neonatal population, specifically for the care of infants under 2 months of age, for whom current recommendations are lacking due to a paucity of data.

Background/objective: The demand for pediatric dermatology services in the U.S. is high, especially at large academic healthcare centers. eConsultation programs provide a solution to poor in-person access by offering diagnostic and management support to primary care providers (PCPs). To determine the real-world utility of eConsultation in pediatric dermatology within a closed system at a major academic center, we assessed the outcomes, diagnostic and management concordance, and predictors of eConsult completion of an asynchronous provider-to-provider pediatric dermatology eConsult program.

Methods: Retrospective cohort study of 900 consecutive outpatient pediatric dermatology eConsult referrals from PCPs at a tertiary academic center from 2017 to 2021.

Results: Of 900 eConsult referrals, 621 (69%) were completed without the need for in-person dermatology follow-up. 46 (5%) were completed but required follow-up. 233 eConsult referrals (26%) were declined, primarily due to medical complexity. Thirty referrals (3%) were declined because of inadequate clinical photos. The PCP communicated eConsult recommendations to the patient/family on an average of 1.6 days (SD 3) after receiving the completed eConsult. eConsults for adolescents were less likely to be completed compared to infants (p = 0.03). Diagnostic and management concordance between PCP and dermatologist was 78% and 67%, respectively.

Conclusions: Provider-to-provider eConsultation provides rapid speciality guidance to PCPs managing low-complexity skin conditions in pediatric outpatients. The lower rate of management plan concordance compared to diagnostic concordance suggests that eConsultation improves outpatient skin management by PCPs.
