1 A woman developed severe mercury intoxication from ingestion of about 2.5 g of mercuric chloride. 2 Antidotal treatment with a dithiol (BAL i.m.) and a monothiol (tiopronin i.v.) was started promptly. 3 Dialysis treatment thereafter markedly increased the elimination of mercury, thus hastening recovery. 4 It is suggested that chelating agents associated with dialysis are an effective treatment for mercury poisoning.
The authors describe moyamoya syndrome in only one of two identical twins. The clinical and angiographic data suggest that it may be an acquired form, but the cause of the pathology remains obscure.

An epidemiological study has been made of acute poisoning cases hospitalised in the Veneto region in 1978 and 1979 and the present paper reports an initial sizeable group of 1721 cases. Young people are most affected (60% of cases below the age of 30), particularly in the first decade of life. The male sex is mainly involved in poisoning due to voluntary substances (alcohol, heroin) while females are most affected by psychoactive drugs. The commonest toxic substances are: psychoactive drugs (26%), alcohol (20%), domestic products (19%), heroin (10%), non-narcotic analgesics (4%), agricultural products (3%) and cardiovascular drugs (2%). In 3% of cases it proved impossible to identify the compound in question and in 13% of poisonings different drugs and substances were involved. The average duration of admission was 41/2 days and support treatment was carried out regularly. Mortality was 0.4% (7 cases), 4 of them due to poisoning by domestic products.
A form is presented for recording acute toxicological case histories for statistical purposes. It includes personal data, case history, social and environmental data, characteristics of the poison(s), history of the intoxication, general and prevailing signs and symptoms, criteria of diagnosis, emergency measures, specific and antagonistic treatment before and during hospitalization, clinical laboratory findings, toxicological analysis, and progression of symptoms until full or partial recovery or death. This form was developed in the course of retrospective research, and can be used either for telephone emergency calls or as a part of the clinical file. Through the elaboration of the compiled forms a strict cooperation between the assisting services and the Specialized Toxicology Centre may allow for better preventive and therapeutic measures.
A form for recording acute toxicological cases has been preliminarily applied to a sample of 436 subjects admitted during 1978 into the hospitals of two districts of the Venetian Region. One was predominately manufacture and industry, and the other a mountain-agricultural area. The latter had medical facilities less uniformly distributed. Through epidemiological analysis, the acute poisoning cases from psychoactive drugs (benzodiazepines, barbiturates, antipsychotic agents, and tricyclic antidepressants) prevailed (37.9%). They were followed by acute cases from street heroin or other opiates in addicts (25.7%) that only occurred in the main town of the more industrialized district. The incidence of the other poisoning cases were in the following decreasing order: household poisons (9.8%), nonnarcotic analgesics (5.1%), agricultural poisons (4.1%), cardiovascular drugs (3.7%), miscellaneous drugs (1.4%), food and plants (1.4%), oral contraceptives (1.0%), viper envenomization (0.7%), and insect bites (0.7%). A rate of 8.5% was due to unidentified compounds. Mortality was 0.9% and death occurred after exposure to corrosives, carbon monoxide, or undetermined substances. Between the two districts there were no marked differences in emergency and general measures that mainly consisted in supportive treatment with forced diuresis (13.9%) and gastric lavage (only 21.4%).
