[Sickle cell disease: from molecular aspects to clinical practice. A case report and a literature analysis]. / Drépanocytose : des aspects moléculaires à la pratique clinique. À propos d'un cas et revue de la littérature.

Sickle cell disease is the genetic disease most frequently detected at birth in France. The comprehension and knowledge of its pathophysiology allow to establish the principles of management for the drepanocytic patient, especially in the perioperative phase. In the light of recent recommendations published for anesthesia of a drepanocytic adult, this clinical case revealed allows to reexamine that subject, with a focus on biological aspects, which are transfusional strategy and antibioprophylaxy. The presented observation is a concrete feature of daily collaboration between clinician and biologist, which is an essential point of the ISO standard EN 15189 concerning laboratories' accreditation.

[Septic shock Fusobacterium necrophorum from origin gynecological at complicated an acute respiratory distress syndrome: a variant of Lemierre's syndrome]. / Choc septique d'origine gynécologique à Fusobacterium necrophorum compliqué d'un syndrome de détresse respiratoire aigu : une variante du syndrome de Lemierre.

We report a case of a female patient of 47 years old who presents in a state of septic shock with acute insufficient respiratory complicated with syndrome of acute respiratory distress, together with a list of abdominal pain and polyarthralgia too. In her case of medical history, it is retained that she has had a intra-uterine device since 6 years without medical follow up. The initial thoraco-abdomino-pelvic scan shows a left ovarian vein thrombosis, as well as the opaqueness alveolus diffused interstitiel bilaterally and an aspect of ileitis. The IUD is taken off because of sudden occuring of purulent leucorrhoea. This results in a clinical and paraclinical improvement, whereas aminopenicillin was administered to the patient since 1 week. The microbiological blood test allows to put in evidence Fusobacterium necrophorum found in a blood culture and is sensitive to the amoxicilline-acide clavulanique and metronidazole. Isolation of this bacteria, classically found in Lemierre's syndrome, allowed to explain the multilfocalization of the symtoms and the list of pain. The whole concerns about a variant of Lemierre's syndrom: a state of septic shock secondary then caused by the anaerobic Gram negative bacilli, which is a commensal bacteria of the female genital tractus, complicated of septic emboli typical.

[Prolonged curarisation following succinylcholine injection on butyrylcholinesterase deficiency and potentiated by a lithium treatment: a case report]. / Curarisation prolongée après injection de succinylcholine sur déficit congénital en butyrylcholinestérase et potentialisée par un traitement au lithium: à propos d'un cas.

Succinylcholine is a short-term curare which degradation depends on its quick hydrolysis by butyrylcholinesterase (or pseudocholinesterase). Thus, a butyrycholinesterase deficiency, congenital or acquired, is a cause of a prolonged neuromuscular block. From an autosomal recessive inheritance, genetic deficiency remains the first etiology. The most frequently discussed variant is the atypical variant which caused a 2 hours prolonged curarisation after administration of succinylcholine. We report a patient who had a prolonged curarisation after succinylcholine's injection, due to a congenital butyrylcholinestérase deficiency and contributed by a lithium treatment. Extubation was only possible 7 hours after administration of curare.

[Thrombotic microangiopathy mimicking a heparin-induced thrombocytopenia]. / Une microangiopathie thrombotique mimant une thrombopénie induite par l'héparine.

We report a case of a 47 years old woman. In her case of medical history, there were vein thrombosis and an allergic to tinzaparin. The patient entered in critical care unit under medical supervision for a multivisceral infarction due to an arterial mesenteric, renal and splenic thrombosis. An heparinotherapy was introduced. A laparotomy was realized because of an occlusion. Small intestine necrozed was removed. 8 days after the introduction of the heparin, there was a thrombocytopenia. Considering the background and the initiale situation, an heparin-induced thrombocytopenia of type II (HTI) was suspected. Whereas the heparinotherapy was stopped, the thrombocytopenia maked worse. Biological tests infirmed HIT's diagnosis. A recurrent anemia in spite transfusions associated to a renal failure suggest a thrombotic microangiopathy which was secondary confirmed. The intensivist is sensibilized to evoke an heparin induced thrombocytopenia when there is a thrombocytopenia under heparin. However, he must not forget diagnosis of thrombocytopenia which required specific investigations and emergency treatment such as thrombotic microangiopathy.
