Failure of omega-3 polyunsaturated fatty acids in prevention of migraine: a double-blind study versus placebo.

Omega-3 polyunsaturated fatty acids (OPFA) have beneficial effects on inflammatory reactions and production of cytokines. They decrease the release of 5HT by platelets and possess vasorelaxant activity. This led them to be tried in the prophylactic treatment of migraine. After 4 weeks of a single-blind placebo run-in period, patients were randomized and treated in double-blind condition by placebo or OPFA 6 g a day for 16 weeks, followed by a 4-week placebo run-out period. The intention to treat population included 196 patients. Those who received all four treatment periods included 96 patients taking OPFA and 87 taking placebo. The primary efficacy analysis was the number of migraine attacks during the last 4 weeks of treatment. During this period, the mean number of attacks was 1.20 +/- 1.40 in the OPFA group and 1.26 +/- 1.11 in the placebo group (NS). The total number of attacks during the 4-month period of the study was significantly different between groups: 7.05 in the placebo group, 5.95 in the OPFA group (P = 0.036). Mean intensity, mean duration of the attacks and rescue medication use, were not significantly different between the two groups. Except for a significant difference against OPFA for eructations, the tolerance was satisfying. Despite a run-in placebo period of 1 month, a very strong placebo effect was observed in this trial: 45% reduction of the attacks between run-in and 4-month treatment period (55% in the OPFA group, P = 0.058). Finally, this large study did not confirm two previous studies based on a small number of patients.

[Treatment of migraine attacks].

The authors have presented a review of the main controlled studies on drug treatment for the management of migraine attacks: non-steroidal anti-inflammatory drugs (NSAIDs), rye ergot derivatives, and the recently commercialized triptan group of drugs. An overview is provided of their specific properties, indications and contraindications, and their respective use in the treatment of migraine headaches.

[Longitudinal study of radiologic anomalies in subjects working in asbestos-insulated buildings].

The respiratory effects of environmental pollution by asbestos was examined in a cohort of subjects working inside university buildings partly insulated with asbestos containing materials (University of Jussieu in Paris). The present study concerned 727 subjects having undergone two standard radiographic examinations (postero-anterior and oblique chest x-ray) in the period 1981-1992. The first examination was realized between 01/01/81 and 31/12/85 and the second examination took place between 01/01/86 and 31/12/92. The subjects were classified into three groups according to their exposure status: the group G1 consisted of 161 workers occupationally exposed to asbestos; the group G2 comprised 416 subjects working for at least 15 yr in asbestos-insulated buildings without known occupational exposure to asbestos; the group G3 consisted of 150 workers working for at least 15 yr in the university with no known exposure to asbestos. Whatever the radiological abnormalities considered, no significant difference was observed between G2 and G3 in cross-sectional analyses of the two phases. The group G1 exhibited a significantly higher prevalence of pleural thickening compared to the other exposure groups after adjustment for confounding variables. Detailed examination of oblique x-ray allowed to confirm that pleural thickening were largely due to extrapleural fat. Concerning the changes in pleural abnormalities between the two phases of the study, no difference was observed between G2 and G3. This study was unable to show any excess of radiographic chest abnormalities among subjects working in asbestos-insulated buildings compared to non-exposed subjects. However, the participation in the second phase of examination was 51.2%. The study is still on-going. Therefore, it would be necessary to continue to follow-up the subjects because respiratory disorders could occur after a long latent period.

[Is human Dirofilaria (Nochtiella) repens parasitosis mor frequent than it appears on the Mediterranean coast?].

Some observations of human parasitism by Dirofilaria (Nochtiella) repens are frequently enough reported but they are also individually reported by different authors. Nïmes's geographical situation makes of it a privileged observatory for this helminthiasis. The worm's maturity varies depending on the subjects: the sensitivity of those and the clinical reactions are of a large variety. The ones that seem to be constant are the parasit's migrations in the different territories during a lot of months. It is the case in the observation reported here; in another article, we have shown the possibility of an intraperitoneal migration which discovery can be only of an extreme fate. Next to some noisy manifestations, other cases stayed quiet advise the adaptation of some autochtones submissed to iteratif infestations.

[A case of disseminated Encephalitozoon intestinalis microsporidiosis in an AIDS patient in Nîmes].

The pathogene's role importance of the microsporidia in nature is considerable. The human being, easily in contact, presents clinical manifestations only with some of them and in a very occasional manner. The increased frequency of the immunodepression has permitted to describe recently a new protozoon, Encephalitozoon intestinalis (alias Septata intestinalis) of the family of the Glugeidae and the human illness of which it is the agent. This parasitose is interesting to be presented because of its rarity and its circulation to organs far from one another. The diagnostic has been done thanks to the only optic microscope and confirmed from its visible efficacity of one cure of albendazole. The pyrimethamine could present a relative efficiency on a relapse of the sinusitis.

Pneumocystis carinii infection of bone marrow in patients with malignant lymphoma and acquired immunodeficiency syndrome. Original report of three cases.

Pneumocystis carinii (PC) pneumonia was reported with increased frequency in patients presenting with acquired immunodeficiency syndrome (AIDS) or in patients receiving immunosuppressive chemotherapy for hemopathies. Extrapulmonary dissemination of PC is rare. In this study, three patients had PC infection of the bone marrow. Two of them presented with malignant lymphoma that had apparent immunosuppression, and the third patient presented with AIDS. In all three cases, such an infection was observed before or concomittantly with PC pneumonia. A bone marrow biopsy, bone marrow aspirate, or both can be useful, readily available tools for the diagnosis of a PC infection and especially its dissemination in patients with malignant lymphoma after intensive treatment or in patients with AIDS. The appreciation of such a dissemination may have some implications in the treatment of PC infection.

[Pneumocystis carinii in the bone marrow].

Pneumocystis carinii is observed in the bone marrow of two adults immuno-compromised; the initial diseases are on the one hand a Hodgkin's disease, on the other hand a malignant lymphoma for immunocytoma type, which necessitate heavy and invalidating treatments. A Pneumocystis carinii pneumonia with respiratory distress seems to have carrying away two patients death. Eventually pathogenic part of the parasite in the bone marrow localization.

Intraperitoneal insulin in uraemic diabetics undergoing continuous ambulatory peritoneal dialysis.

The kinetics of absorption of intraperitoneally administered insulin were studied in nine uraemic insulin-dependent diabetics undergoing continuous ambulatory peritoneal dialysis (CAPD). In each of three studies 20 U of regular insulin was directly injected as a bolus into the peritoneal cavity through an indwelling Tenckhoff catheter. In two procedures the insulin injection was followed by the instillation of either 2 litres of 1.5% dextrose dialysates or 2 litres of 4.5% dextrose dialysate. In the third 20 ml of saline was used to flush the tubing. Plasma free insulin values rose more rapidly and reached significantly higher concentrations (55.6 +/- 18.8 mU/l) when the insulin had been injected into an empty peritoneal cavity than when it was followed by dialysate. These differences were observed despite the fact that most of the insulin injected was retained by the patients. Since the plasma insulin values did not differ after instillations of dialysate containing 1.5% and 4.5% dextrose, the osmolality of the dialysate seemed not to affect insulin absorption, and the dilution of the insulin probably delayed its transfer through the peritoneum. These findings suggest that insulin given intraperitoneally to patients undergoing CAPD will be most effective if it is given into an empty peritoneal cavity at least 30 minutes before the dialysate is instilled.

Correlation between the nature and amount of carbohydrate in meal intake and insulin delivery by the artificial pancreas in 24 insulin-dependent diabetics.

We have studied the effects of mixed meals and dextrose intake on blood glucose and insulin delivery by the artificial pancreas in 24 insulin-dependent diabetics. A group of 12 patients had 3 mixed meals containing at random 20, 40, and 60 g of complex carbohydrate along with protein and fat; another group of 12 diabetics, comparable in weight, age, and duration of diabetes, received at random 20, 40, and 60 g of dextrose. Dextrose ingestion led to a higher initial blood glucose increase than did the mixed meal, but the duration of blood glucose increase lasted significantly longer after the mixed meal than after the dextrose load. The areas under the curves of hyperglycemia were not significantly different. There was a high (but not linear) correlation between the total amount of insulin delivered in order to restore initial blood glucose values and the amount of CHO consumed. There was no correlation with age, body weight, duration of diabetes, nor with the nature and order of administration of the CHO load; 5.1 +/- 1.6 to 13.7 +/- 2.1 units of insulin were needed for a period of 94 +/- 11 to 132 +/- 11 min. It is suggested that some of the data obtained in this study might be useful in the programming of an open-loop insulin infusion system.
