Spontaneous periodic episodes of hypothermia still defy medical knowledge. In 1969, Shapiro et al. described the first two cases of spontaneous periodic hypothermia associated with agenesis of the corpus callosum. Recently, Dundar et al. reported a case of spontaneous periodic hypothermia and hyperhidrosis without corpus callosum agenesis, suggesting that the periodic episodes of hypothermia might be of epileptiform origin. Here we describe two paediatric patients with spontaneous periodic hypothermia without corpus callosum agenesis and demonstrate, to our knowledge for the first time, altered levels of neurotransmitter metabolites within the cerebrospinal fluid.

D006945 Hyperhidrosis Excessive sweating. In the localized type, the most frequent sites are the palms, soles, axillae, inguinal folds, and the perineal area. Its chief cause is thought to be emotional. Generalized hyperhidrosis may be induced by a hot, humid environment, by fever, or by vigorous exercise. Hyperidrosis
