[The clinico-dermatological and morphological characteristics of the hair involvement in children with chemical poisoning].

A syndromal condition, transitory neuropsychic symptoms and signs of catarrhal inflammation of upper respiratory tract mucosae and alopecia, develop in children with symptoms of chemical poisoning due to exposure to heavy metal salts. Electron microscopy shows changes that evidence a high incidence of dying and dead hair. Alopecia was more frequently subtotal and there was a tendency to hair growth restoration after the cause of the condition was removed and prophylactic measures carried out.
