Familial dysautonomia, also known as Riley-Day syndrome, is a disorder of autonomic nervous system with an autosomal recessive mode of inheritance. Reduction and/or loss of unmyelinated and small myelinated fibers is found, as reduction of dopamine beta-hydroxylase in blood. The diagnosis is based on clinical features: diminished lacrimation, insensitivity to pain, poor temperature control, abolished deep tendon reflexes, postural hypotension, vomiting attacks, poor motor coordination, and mental retardation. The treatment is symptomatic and many children die during the first years of life, usually as a result of repeated aspiration pneumonia. We report the case of a 1 year-old child with familial dysautonomia.

Disulfiram is used in alcohol rehabilitation because it inhibits aldehyde dehydrogenase and consequently causes the disulfiram-ethanol reaction (vomiting, vertigo, anxiety, cardiovascular effects) after ingestion of alcoholic beverages. However, adverse effects on the central nervous system (for the most part psychotic reactions, acute organic brain syndrome, catatonia) may appear as a direct result of the drug itself. Disulfiram and its metabolite carbon disulfide inhibit dopamine beta-hydroxylase, increasing the levels of dopamine and reducing those of norepinephrine in the central nervous system. We observed direct disulfiram-induced toxicity on the central nervous system in 8 abstinent patients in whom a disulfiram-ethanol reaction had been excluded. Risk is increased when 1) excessive amounts of the drug are ingested; 2) the patient is already suffering from a major psychiatric illness; 3) the patient has anatomical brain lesions. In all cases observed, the toxic effects appeared in the first weeks and were reversed after suspension of the drug (except in one patient who died from severe bronchopulmonary infection). We thus suggest the following protocol: 1) physical examination and interview 3-4 weeks after initiation of treatment; 2) as a general rule, in abstinent patients, the lowest possible maintenance dosage should be administered. This strategy, despite the risk of underdosage, meets the goals inherent in an integrated medical and psychosocial approach to the treatment of alcoholism with which these patients seem better able to comply.
