[Pharmacological treatment of post-traumatic behavioural disorders].

OBJECTIVE: Literature review of the data concerning pharmacologic treatment of post-traumatic behavioural disorders. This review is limited to the treatment of agitation, excitation, mood lability, hostility and agressivity as defined by the NRS and excludes pharmacologic treatment of mental slowness, cognitive disorders and depression. METHODS: Medline interrogation using keywords Traumatic Brain Injury, Agitation, Agressivity, Behaviour, Pharmacology, Neuroleptics, Benzodiazepines, Carbamazepine, Valproate, Buspirone, SSRI, Propanolol, Methylphenidate and review of recent contents. The data finally includes 29 original studies. RESULTS: The overall level of evidence is quite low as the data mainly consist in open studies and case reports. These data and data from reviews or didactic articles suggest the efficiency of a variety of treatments. Mood-stabilizing antiepileptics, and specially carbamazepine constitute together with SSRI antidepressants the first choices. Some data suggest efficiency of buspirone, methylphenidate and atypic neuroleptics. Lithium requires close monitoring but is probably efficient. It is difficult to conclude concerning propanolol. CONCLUSION: The available data is in favour of the use of CBZ and SSRI antidepressants. Further studies are required. It is necessary to establish clear evidence of the efficiency of CBZ and assess the effects of methylphenidate, which is almost not prescribed in France.

[Heparin induced thrombocytopenia: case report with acute thrombotic complications and literature review].

PURPOSE: Review of the frequency, clinical and biological features and treatment of type II heparin-induced thrombocyopenia. METHODS: Case report and literature review. RESULTS: A 65 years old woman received as antithrombotic prophylaxis low molecular weight heparin (LMWH) after prosthetic knee replacement. Day 8, asymptomatic deep vein thrombosis was discovered after systematic echodoppler examination. Curative anticoagulation was started with LMWH. A fall in the platelet count (17 G/L) was noted day 12. Danaparoid was immediately introduced and heparin discontinued. However, day 16 a massive pulmonary embolism occurred which required transfer to an intensive care unit. Danaparoid was changed for lepirudin the same day. It took longer than three weeks for platelet count to return to normal value after heparin discontinuation. The suspicion of heparin-induced thrombocyopenia was confirmed by specific tests. DISCUSSION: HIT type II are rare but life-threatening and thrombosis events are the most frequent complications. The diagnosis is a high probability proved by both clinical and biological patterns. The treatment consists in alternative thrombin inhibitors such as danaparoid and lepirudin. The platelet count usually requires less than ten days to recover normal values after heparin withdrawal. Cases in which the delay to a normal platelet count exceeds 3 weeks have been reported specially after LMWH therapy. CONCLUSION: Type II HIT are rare but life-threatening events can occur. The platelet count check-up during heparin therapy must be systematic.

Clinical evaluation of prior suicide attempts and suicide risk in psychiatric inpatients.

BACKGROUND: In practice psychiatrists rely on their own experience and intuition to evaluate the suicide potential of individual patients, but the algorithms for the decision-making process remain unclear. OBJECTIVES: (1) to establish models for the decision making process for evaluating suicide risk; (2) to simulate the impact of information concerning the number of previous suicide attempts on the clinician's ability to detect patients who performed medically serious suicide attempts (MSSAs). METHODS: Four decision models (linear, dichotomized, hyperbolic, and undifferentiated) depicting the influence of the number of previous suicide attempts on the clinician's recognition of MSSAs in 250 psychiatric inpatients were elicited and tested by a series of discriminant analyses. RESULTS: The dichotomized model ("all or none") was found to be the most efficient in detecting medically serious suicide attempts. CONCLUSION: The "all or none" paradigm seems to be the most appropriate way to evaluate the weight of previous suicide attempts in the decision-making process identifying medically serious suicide attempt patients.
