Caustic diaper dermatitis and encephalitis secondary to the application of talcum contaminated with hexachlorophene

: Five observations of infants with transcutaneous intoxication by 6,3 p. 100 hexachlorophene contaminated talcum powder are reported. The diaper dermatitis is particular because of its topography (red pants shape), of its sudden occurring, of its papyraceous aspect evoking caustic origin, and of its association with severe encephalopathy. The neurological signs start with epileptic fits leading rapidly to coma. Prognosis is serious leading either to death or to paraplegia. Enquiry on that epidemic shows that mortality raised up to 18 p. 100. The neurological signs with oedematous degeneration of myelin are characteristic of hexachlorophene toxicity. Plasma levels of toxics range up to 15,94 mg/ml i.e. 30 times more than the rates observed by Curley in a premature washed with a commercial solution containing 3 p. 100 hexachlorophene. During a toxic neurological syndrome, the existence of diaper dermatitis with red plants shape must lead to an aetiological diagnosis of the possibility of transcutaneous intoxication even if the product seems as harmless as talcum powder.
