What's New Pediatric Infections

Rounding out the first day, Elizabeth Swanson, MD, presented an engaging review of emerging trends and treatments in pediatric infections, offering updates across various dermatologic conditions. She began with herpes zoster, noting an increase in cases among children due to waning immunity from chickenpox vaccination and emphasized the importance of antiviral treatments like acyclovir and valacyclovir, along with precautions for unvaccinated individuals and pregnant women. Dr Swanson also highlighted the efficacy of intralesional HPV vaccines for recalcitrant warts, outperforming intramuscular approaches. For molluscum contagiosum, she discussed the recently FDA-approved cantharidin and other treatment options like topical retinoids and Candida antigen injections, introducing pseudofurunculoid molluscum as a marker of resolution and cautioning against drainage. She also reviewed Gianotti-Crosti syndrome, emphasizing its viral triggers, self-limiting nature, and the use of topical steroids for symptomatic relief.

Dr Swanson continued with practical insights on distinguishing impetigo from HSV through bacterial cultures and PCR testing, addressing recurrent cases by identifying nasal carriers. She explored severe cases of hand, foot, and mouth disease, particularly eczema coxsackium caused by coxsackie A6, which requires targeted eczema management and supportive care. Updates on fungal infections included strategies for managing resistant strains like Trichophyton indotineae and pediatric-friendly treatments for onychomycosis. Concluding her session, Dr Swanson provided practical clinical pearls, offering actionable insights and highlighting the importance of evolving, patient-specific therapies in managing pediatric infections.
