Nappy rash or diaper dermatitis is common among neonates. It is seen as erythema, scaling and chafing on the convex surfaces of the buttocks and other areas in contact with nappies, with sparing of the deeper folds. It has a multifactorial aetiology. Factors which may contribute to nappy rash are water and ammonia in stool and urine, excessive wetness, friction between nappy and skin, soap and detergents, powders and creams and Candida albicans in faeces. Management includes use of good quality napkins, application of emollients, treatment of Candida and bacterial infection and avoidance of powders.
