Foreign Invaders: Pearls and Pitfalls
Description
The presentation addresses pediatric infections and infestations, focusing on recognizing and managing cases, highlighting important nuances through illustrative examples. The first case is about a two-year-old with eczema and atypical hand, foot, and mouth disease caused by coxsackievirus A6. It discusses the importance of distinguishing between this and eczema herpeticum, noting that both can present similarly but have different characteristics and treatment protocols. The second case involves a 15-year-old girl discovering head lice, emphasizing the importance of accurate diagnosis, the timing of itching, and the distinction between nits and other scalp conditions. It covers treatment options while acknowledging the rising challenge of resistance to common treatments like Permethrin. The presentation also delves into neonatal dermatophyte infections like tinea capitis, discussing the necessity to differentiate from conditions like neonatal lupus. Additionally, it highlights the common occurrence of perianal streptococcal cellulitis in children, stressing systemic antibiotic treatment over topical options for effective management. Lastly, it introduces molluscum contagiosum and its associated inflammatory reactions, specifically GCLR, providing clinical insights into lesion management. The speaker encapsulates key takeaways and offers additional resources for reference.

- Atypical hand, foot, and mouth disease (HFMD) can manifest with unusual morphology and distribution compared to classic cases.
- Recognition of enterovirus infections is crucial, as atypical HFMD may involve areas such as the arms, legs, face, and buttocks.
- Diagnosis of head lice should consider the potential absence of itching in first cases and involve careful examination for viable nits.
- Treatment for head lice may involve multiple over-the-counter and prescription options, with awareness of local resistance patterns being essential.
- Systemic treatment is sometimes unnecessary for neonatal cases of tinea capitis, and topical treatments can be effective.
- It is important to differentiate between perianal streptococcal dermatitis and other skin conditions such as guttate psoriasis, especially in children.
- Topical antibiotics alone are often insufficient for perianal streptococcal infections, requiring systemic antibiotic therapy instead.
- In cases of molluscum contagiosum, associated inflammatory reactions like Gianotti-Crosti syndrome can occur and typically resolve within weeks.
- Clinicians must be diligent in monitoring for recurrences and complications associated with pediatric infections and infestations.
