Over the last 10 years, Europe has witnessed the development of the ecstasy phenomenon; this term is used to describe several products sharing more or less the same effects. The most widely used and hence the most well known is 3,4 MDMA, but MDA, MDEA, MBDB and even 2CB or nexus are available. The psychopathological consequences of MDMA use in man are relatively poorly understood. The case reported here involves an acute psychotic episode with residual symptoms after six months, with a sudden onset at least 12 hours after taking alcohol and ecstasy without realising it, in an individual with no previous psychopathology other than a moderate anxiety disorder. Twelve cases of acute psychotic episodes after taking ecstasy have been reported in the literature; two after taking the drug on two occasions and one after a single use. No authors have examined the previous mental state or possible previous psychopathology with any precision. The present subject had not displayed any previous psychotic behavior when tested with a proven standardized interview technique; this was confirmed by his peers and his family. He did, however, show signs of social phobia. Although the personality of an individual is a factor in taking a drug, and probably in the quality of the psychotropic effects experienced, a host of arguments favor the appearance of psychotic symptoms de novo, which were probably related to direct toxicity by MDMA and/or its metabolites on the serotoninergic neurons. 相似文献

We studied a murine monoclonal antibody (211 A6) to von Willebrand factor (vWF) with a view to investigating structure-relationship of plasma vWF. The specificity of this antibody has been substantiated by ELISA tests and indirect immunofluorescence. It reacts with purified vWF, normal plasma but not with plasma or platelets from a severe von Willebrand's disease patient. Monoclonal antibody 211 A6 is a potent inhibitor of ristocetin-induced platelet aggregation. The 125I-FVIII/vWF binding to platelets in presence of ristocetin is totally inhibited by low 211 A6 concentrations. Thrombin-induced binding of vWF to platelets is not affected by 211 A6. The ability of this antibody to inhibit platelet adhesion to subendothelium and to collagen was investigated with a perfusion model. The complete inhibition of platelet adhesion by 211 A6 questions the similarity or the interrelationship in vWF domains involved in ristocetin-induced platelet functions and platelet adhesion. 相似文献

Induction of immune tolerance with recombinant factor VIII in haemophilia A patients with inhibitors 总被引:3,自引:0,他引:3
Batlle López Brackmann Gaillard Goudemand Humbert De Moerloose Maass Mauz-Körholz Sultan & Stieltjes 《Haemophilia》1999,5(6):431-435
We report on 11 patients (nine unrelated and a brother pair) with severe haemophilia A and factor VIII (FVIII) inhibitor, in whom immune tolerance (IIT) was induced with recombinant FVIII (r-FVIII). Their age ranged from 11 months to 47 years. The number of exposure days (ED) at inhibitor detection varied from 11 to 130. Nine of the 11 patients were high responders [>10 Bethesda units (BU)] with peak inhibitor levels ranging from 10 to 566 BU. The other two were low responders with peak levels between 0.7 and 2 BU. Before inhibitor detection, the patients had been receiving products of various purities. The IIT regimens were very heterogeneous, and the treatment schedule varied from a short period with 50 IU kg–1 every 2 days, followed by 100 IU kg–1 every 2 days and then 220 IU kg–1 daily. The outcome was considered successful when the inhibitor level fell to 0.6 BU or lower after IIT treatment. The outcome overall was successful in nine out of 11 patients (81.8%), with the nine successful cases comprising seven of the nine high responders (77.8%) and the two low responders. Definite failure of IIT was observed in one high responder after two different IIT regimens. A second high responder is still on IIT treatment. All patients in whom IIT was successful are currently receiving r-FVIII on demand or prophylactically at various dosages. Despite the variability of the patient characteristics and the IIT schedules, this study demonstrates that r-FVIII represents an effective alternative for the eradication of inhibitors through IIT. 相似文献

We report 2 cases of occlusion of the internal carotid artery in young, non-atherosclerotic patients with essential thrombocythemia (ET). This complication of ET seems to be rare, but is probably underdiagnosed since transient ischemia, which is frequent in ET patients, is seldom explored by angiography. The excess of thrombocytes and the thrombopathy may account for the microvascular complications, but in the absence of any other contributory factor, occlusions of large arteries, such as the ICA, is more difficult to explain. 相似文献

Meningococcemia and purpura fulminans in adults: acute deficiencies of proteins C and S and early treatment with antithrombin III concentrates 总被引:5,自引:0,他引:5
F. Fourrier M.D. P. Lestavel C. Chopin A. Marey J. Goudemand A. Rime J. Mangalaboyi 《Intensive care medicine》1990,16(2):121-124
It has been recently suggested that an acquired deficiency of proteins C and S could contribute to the pathogenesis of meningococcemic
purpura fulminans (PF) in children. Our study was designed to measure the levels of antithrombin III (AT III), protein C,
and protein S during adult PF and to determine the effects of an early infusion of high doses of AT III concentrates on clinical
and biological alterations of PF. We studied five consecutive adult patients with meningococcemia (type B) and PF. The levels
of AT III, protein C (antigen and activity), and protein S (total and free) were measured at admission and 24 h and 1 month
later. The treatment included in each case: amoxycillin, dobutamine and high doses of AT III concentrates. All patients survived
and were discharged without any sequelae. At admission, biological data were consistent with severely depressed protein C
and protein S levels and moderately decreased AT III levels, without any discrepancy between protein C antigen and activity.
After 24 h, AT III and protein S levels were within normal ranges, whereas protein C levels were still depressed. These data
are consistent with the theory of a particular imbalance in the anticoagulant systems during meningococcemic PF, contrasting
with the usual findings observed during septic disseminated intravascular coagulation. The possibility must be considered
that high doses of one anticoagulant (AT III concentrates) could compensate for the acute decrease in the other (protein C
system). 相似文献

Catatonia and consultation-liaison psychiatry study of 12 cases 总被引:1,自引:0,他引:1
Cottencin O Warembourg F de Chouly de Lenclave MB Lucas B Vaiva G Goudemand M Thomas P 《Progress in neuro-psychopharmacology & biological psychiatry》2007,31(6):1170-1176
Nowadays, catatonia is no more considered as a subtype of schizophrenia. Catatonia seems more frequently associated to mood disorders as well as general medical conditions. It is sometimes difficult to associate formally a medical etiology to this syndrome. But we found, in the literature, three groups of associated general medical conditions: neurological disorders, drug induced and toxic induced conditions, metabolic conditions. We present a prospective study of 12 clinical cases of catatonia due to general medical conditions we realized in the Consultation-Liaison Psychiatry Department of the University Hospital of LILLE (France) during a period of 5 months. We find coherent data with the literature. However, our results suggest that if medical conditions precipitate the catatonia syndrome, they are rarely its only etiology. We think that if somatic factors are co-morbid with psychiatric conditions they do not necessarily predominate as the target of treatment. The treatment of the catatonia must be a priority and remain symptomatic, to allow in parallel the specific treatment for the somatic disorder or the psychiatric disorder. 相似文献

The relationships between the Platelet Function Analyzer (PFA)‐100 and von Willebrand factor (VWF) levels and bleeding score (BS) were evaluated within a multicentre project on Molecular and Clinical Markers for the Diagnosis and Management of type 1 von Willebrand disease (MCMDM‐1VWD). PFA‐100 closure time, either with epinephrine (EPI) or adenosine diphosphate (ADP)‐cartridges, was measured in 107 index cases, 105 affected and 71 unaffected family members, and 79 healthy controls. By regression analysis VWF levels were strongly related to both closure times, with a non‐linear progression. In a multiple stepwise regression model, age‐ and sex‐adjusted PFA‐100 ADP and VWF ristocetin cofactor activity (VWF:RCo) were independently associated with BS. Most of the variation of BS was predicted by PFA‐100 ADP and VWF:RCo alone. In the subgroup of patients with subtle abnormalities of the multimeric pattern, VWF was invariably reduced and closure time prolonged in almost all of them. Neither PFA‐100 ADP nor EPI closure times appeared to significantly improve the diagnostic capability of VWF antigen (VWF:Ag) measurement. Thus, in an unselected population a normal PFA‐100 would be useful to exclude VWD, but whether it could replace the more specific VWF assay in patients with significant mucocutaneous bleeding symptoms remains to be investigated prospectively. 相似文献
