Scabies, lice, and fungal infections

Scabies and pediculosis capitis are frequent and often unrecognized causes of multiple streptococcal and staphylococcal pyodermas. Permethrin 1 per cent creme rinse (NIX) for head lice, and permethrin 5 per cent topical cream for scabies are new, highly effective, safe, and cosmetically elegant treatments which have shown superiority over older remedies. In populations in which pediculosis and scabies have resisted traditional lindane therapy, patients promptly responded to these permethrin products. Scabies in nursing homes is a persistent and expanding problem which demands a high level of diagnostic suspicion and an integrated approach to management. For fungal infections, several new broad-spectrum oral and topical agents have been introduced. Their successful use is enhanced by appropriate diagnostic tests which can be performed in the office setting. Recommendations and references are given to assist the physician in diagnosis and choice of therapy.
