We observed two cases of spontaneous rupture of an apparently healthy spleen in two patients who were taking ticlopidine as anti-platelet aggregation treatment. The notion that the spleen was apparently healthy was based on well-defined criteria, essential for the imputability of the spontaneous lesions. In general drug-induced spontaneous ruptures of the spleen have been reported for anticoagulants but no case due to antiplatelet aggregation has been reported to our knowledge. The analysis of these two cases and a review of the recent literature suggests that ticlopidine was the causal agent in these two cases of splenic rupture.
The authors report on the observation of an epileptic woman who showed the clinical and electro-encephalographic symptoms of an overdose of barbiturates when undergoing treatment associating Depakine and Gardenal. Resumption of the treatment results in identical symptoms. The potentialisation of this association and the mechanism by which it acts are as yet unknown.
Products used in a toxicomaniac way are in rapid change, and different from different area. Users too have to be better known. Authors present a simple survey method of these products, based on sample use. First results seem to be correct. These method may be used, associated with others, in a network as those existent for many years in the United States.
A study of benzodiazepine impregnation of 234 drivers involved in road accidents showed a higher level of impregnation than that usually observed in the general population and a different frequency of this impregnation in the two populations. Although a significant correlation was found between responsibility of the driver and positivity of benzodiazepine assays, this result must be interpreted with caution and does not permit to attribute the responsibility for the accident to the presence of benzodiazepine in blood.

By 1990, the Clin Midy (SANOFI) laboratory had modified the dose of Cantor tablets: the content of active drug (minaprine) increased (50 to 100 mg). Therefore, acute intoxication by minaprine can be serious, with generalized seizures, resisting the classic treatment. We tried to evaluate the possible consequences of this change of dose for the gravity of suicide attempts. 1091 voluntary acute intoxications have been collected by the national French Poisons Centres data bank, 226 of them by the Poisons center of Marseilles. We have compared, by the chi 2 method, the frequencies of seizure and death, before and after 1990. Results are significant, confirming an increased gravity of these intoxications since the modification of dosage. Then, the laboratory reduced the number of tablets per box. We don't know if this measure will be efficient.
The aim of O.P.P.I.D.U.M. is the survey of products used by drug addicts. A five year survey, based on regular pools, has provided interesting results. 1,283 patients (80 per cent men, about 27 years old, 1/4 employed) used 2,241 drugs. The most frequent was heroin, followed by benzodiazepines, cannabis and cocaine. Flunitrazepam was the most commonly misused product, taken by users who started consumption earlier, with a higher rate of unemployment and imprisonment. Cocaine was as often taken intravenously as by sniffing, and most often used before imprisonment. Ecstasy (M.D.M.A.) has appeared recently. Codeine taken alone was used by subjects older than the heroin users, more frequently employed and virtually never prison inmates: this suggests the existence of an unofficial detoxication and substitution process. Confidence of clinicians needs anonymity of the records and return of information. Such a campaign is about to be launched.
Using the data bank developed by the Computer Service of the Lyon Hospitals, the Anti-Poisons Centre of Marseille presents an initial study of intoxications by appetite suppressants. The work was complemented by a simultaneous study using conventional manual techniques. An epidemiologic review of 1973 and an approximate assessment of toxic doses in the adult and child were possible. They should be of particular use in answering telephone enquiries at anti-poison centres.
