[Antipsychotic prescription assessment in general practice: metabolic effects]. / Évaluation de la prescription d'antipsychotiques en médecine générale: conséquences métaboliques.

INTRODUCTION: Second-generation antipsychotics have improved living conditions of patients affected by severe mental illness. Some of them can induce weight gain with metabolic complications. Furthermore, they are prescribed to vulnerable patients, with comorbidity and high cardiovascular mortality rate. Prevention of a metabolic syndrome by simple measures improves patient's physical health. General practitioners are privileged partners for psychiatrists. OBJECTIVES: This study was conducted to assess the prevention and management of a metabolic syndrome in patients treated with antipsychotics in general practice. With this in mind, at first we needed to explore how general practitioners prescribe antipsychotics. METHODS: To assess the general practice, we interviewed 204 general practitioners in the Hauts-de-Seine. Our database was the yellow pages of this area (September 2007). We then conducted a random draw using random digits. We called 507 general practitioners, 410 of whom were sent a questionnaire. We received the return of 204 questionnaires. Each questionnaire consisted of four parts: the general practitioner's profile, psychiatry in his/her practice, the prescription of antipsychotics and the management of metabolic syndromes in patients treated with antipsychotics. RESULTS: The general practitioner's response rate was 49.7%. The results show that although they prescribe antipsychotics, general practitioners need more information on these molecules and on their side effects. Indeed 57% of them feel they are not given enough information on antipsychotics, but 69% have already initiated antipsychotic treatment and 17% do so regularly. Furthermore, a metabolic syndrome is insufficiently detected by general practitioners, although they know of its prevalence after the introduction of antipsychotic treatment. Thus, 81% reported having been confronted with this problem, but only 54% of them calculated the body mass index of patients taking antipsychotics, and 26% measured waist circumference. These results are consistent with studies tracking metabolic syndrome performed in all patients, so, general practitioners do not conduct specific monitoring of patients on antipsychotics. However, they are faced with difficulties related to adherence to treatment because of weight gain. In such cases, 16% of respondents start a new treatment, without a psychiatrist's opinion. These results confirm the results of previous studies on the risks of such prescriptions in general practice, when not supervised. CONCLUSION: In conclusion, we suggest that information of general practitioners about their role in prevention of metabolic syndromes should be improved, and psychiatrists and general practitioners should be informed on the necessity of joint care of patients affected by severe mental illness.

[Alcohol and epilepsy: a case report between alcohol withdrawal seizures and neuroborreliosis]. / Alcool et épilepsie : une illustration clinique entre convulsions de sevrage et neuroborréliose.

OBJECTIVES: This work consists in a study of the links between alcohol, a psychoactive substance and different related epileptic manifestations in order to clarify predominant factors both on conceptual, clinical and therapeutic levels. BACKGROUND: If alcohol is a frequent risk factor for seizures, its scientific evidence is less clear and ad hoc literature is rich in controversies and not firmly supported by systematic surveys. Alcohol has variable roles in the physiopathological determinism of seizures, the nosographical status of which needs to be clarified: alcohol withdrawal seizures, alcoholic epilepsy, and sometimes symptomatic epilepsy caused by coincidental disorders. METHODS: A synthesis of relevant literature describing the links between alcohol and epilepsy is illustrated by a clinical case: a patient admitted in our psychiatric ward for chronic alcoholism had had two seizures questioning their nosographical status. An infectious process with protean neurological manifestations, neuroborreliosis, was diagnosed. DISCUSSION: Three distinct clinical pictures illustrate the links between alcohol and epilepsy: the first, convulsive inebriation corresponds to a seizure during severe acute alcohol intoxication. The second deals with alcohol withdrawal seizures following a partial or complete sudden withdrawal of alcohol; these are the clinical features the most documented in the literature representing, with delirium tremens, the main complication of alcohol withdrawal. The third clinical picture, alcoholic epilepsy, is characterized by repetitive seizures in patients presenting alcohol abuse without former history of epilepsy or other potentially epileptic disorder, and without relationship to alcohol withdrawal or acute alcohol intoxication. Acute and chronic effects of alcohol on central nervous system have been depicted, while a unified classification of alcohol related seizures has been recently established by Bartolomei. This classification based on the Ballenger hypothesis of kindling (1978) could explain withdrawal and hazardous seizures as clinical expressions of the same epileptogenic process over different stages. Although theoretically criticized, such a model offers a conceptual interest while able to unify the varied understanding of convulsive crises related to alcohol, and a practical one, whilst being a basis for a therapeutic approach. Our clinical case illustrates the delay in the diagnosis established after two iterative generalized seizures, 72 hours after the beginning of a programmed weaning of a patient presenting alcohol dependency. If the withdrawal seizure hypothesis was underlined, some data led to symptomatic epilepsy. Firstly atypia, the well-supervised preventive treatment of convulsion did not avoid seizures. Secondly, the EEG showed focal anomalies strongly linked in the literature with a cerebral disorder, which was confirmed by MRI; thirdly, cognitive alterations, which are not usual in alcohol dependency, were observed clinically and confirmed by neuropsychological tests. Finally a neuroborreliosis was diagnosed, while the main neuropsychiatric complications of Lyme disease were described. In accordance with the recommendations made by some authors, it appeared legitimate to consider neuroborreliosis as a potential differential diagnosis of every atypical psychiatric disorder, the interest of such an identification laying in the existence of a specific treatment.
