[Postpartum cerebral thrombophlebitis. A case secondary to acquired antithrombin III deficiency].

The cerebral thrombophlebitis is a rare complication of the pregnancy and the postpartum. We report a case of a 21 year-woman presenting a post-partum cerebral thrombophlebitis, secondary to an acquired deficiency of antithrombin III. The clinical symptoms of cerebral thrombophlebitis can be misleading. The angiography and the magnetic resonance imaging permit the diagnosis. The treatment is relied on anticoagulating heparin therapy. This treatment will be adapted in case of coagulation's factors deficiency that must be searched in any thromboembolic accident having an unusual localization.

[Combination of Emla cream and nitrous oxide for venous cannulation in children].

OBJECTIVE: To assess the efficacy of an combination of Emla cream and N2O for venous cannulation in children. STUDY DESIGN: Prospective, randomized, double blind trial. PATIENTS: The study included 75 unpremedicated children, aged 3 months to 5 years, ASA physical class I and II, undergoing an elective surgical procedure, randomized into three groups. METHODS: In group I and III, children received Emla cream one hour before entering the theatre. In group II, children received a placebo. Children of group I and III also inhaled 50 vol% nitrous oxide in oxygen and those of groupe II 100 vol% oxygen, 3 min prior and during venous cannulation. A blinded observer recorded the following items: pain assessment with CHEOPS scoring, conditions of venous puncture and behaviour of children. Heart rate, blood pressure and oxygen saturation were assessed at three timepoints: before, 3 min after facial mask application and following venous cannulation. RESULTS: There were non significant differences between the three groups for the conditions of venous cannulation. The CHEOPS score was better in group I (7[4-11]), compared to group II (10[6-13]; P < 0.01) and to group III (9[6-12]; P < 0.01). CONCLUSION: Emla cream combined with nitrous oxide is effective for venous cannulation in providing satisfactory analgesia and in controlling anxiety elicited by the vision of needle.

[Fatal hepatitis in a young child: probable role of halothane].

A 3-year-old boy, who underwent multiple anaesthetics including halothane in a short period of time, developed 3 days after the last operation abdominal pain, jaundice and fever. Laboratory tests showed hepatic failure, with cytolysis, cholestasis and eosinophilia. Tests for hepatitis A, B, C, CMV and EBV were negative. No other causes of postoperative jaundice were identified. Despite symptomatic treatment, the child died 5 days after the last anaesthetic. Post mortem liver biopsy showed massive hepatic necrosis. The authors discuss factors increasing the risk for halothane-hepatitis, especially multiple exposures.

[Tetraplegia following cervical stab wound].

We report two cases of tetraplegia caused by cervical stab wounds. In the first one, in a 34-year-old patient, the injury caused an immediate tetraplegia from cervical spine section and had a rapid lethal outcome. The second case occurred in a 30-year-old woman, who experienced a progressive tetraplegia associated with a Brown-Séquard syndrome from an oedema of the bulbo-spinal junction. Three months later, the motor recovery was satisfactory, however a thermo-algesic hemi-anaesthesia still persisted after the 6th month.

[Anaphylactic shock caused by application of fluorescein on the ocular conjunctiva].

OBJECTIVE: Fluorescein is widely used in ophthalmology. Side effects related to fluorescein occur frequently but are usually benign (nausea, vomiting, lipothymia). Severe side effects are rare. We report a case of anaphylactic shock due to local application of fluorescein. CASE REPORT: A 70-year-old woman was treated for ocular conjunctivitis with local application of fluorescein. Cardiac arrest occurred due to anaphylactic shock. Resuscitation was successful. DISCUSSION: The gravity of certain complications related to the use of fluorescein underline the importance of adequate resuscitation material and adapted treatment.

[Paraplegia after cardiac arrest].

We report a case of a permanent flaccid paraplegia, with a sensory loss at T12 level, not associated with cerebral damage, subsequent to a cardiac arrest of 15 minutes duration, in a 67-year-old patient, undergoing haemorragic surgery for gangrenous purulent cholecystitis. Besides cardiovascular collapse and subsequent circulatory arrest, possible favouring factors include anatomical anomalies in the territory of anterior spinal artery, surgical posture with hyperlordosis generating venous stasis, emergency haemostatic maneuvers with compression of the arterial territory providing spinal blood supply. Spinal cord lesions are probably more frequent than expected, as the often associated cerebral anoxic encephalopathy impedes their recognition. Only a systematic anatomopathological examination of the spinal cord, in patients who died after a cardiac arrest, would provide the accurate incidence of spinal complications.

[Does oral ondansetron reduce the incidence of nausea and vomiting after surgery for strabismus in children?].

OBJECTIVE: To compare the efficacy of oral ondansetron with oral metoclopramide for the prevention of postoperative vomiting and nausea in children undergoing strabismus surgery. STUDY DESIGN: Prospective, randomized, double-blind trial. PATIENTS: Thirty children of physical class 1, age 9 +/- 4 years, scheduled for strabismus surgery, were randomized into two groups (ondansetron and metoclopramide). METHODS: In the ondansetron group, the children received the first oral dose of ondansetron (4 mg) 1 hour before induction of anaesthesia and the other doses 8 and 16 hours later. In the metoclopramide group, children received metoclopramide (5 mg) in the same conditions. Anaesthesia was induced with thiopentone, vecuronium and fentanyl and maintained with halothane and N2O/O2. Patients were evaluated by an independent observer for nausea and emesis in recovery room (0-2 h) and on the ward. The adverse effects of oral ondansetron and metoclopramide were assessed. RESULTS: There were non-significant differences between the two groups for incidence of nausea and vomiting (40% and 53% in ondansetron group versus 33 and 60% in metoclopramide group, respectively. CONCLUSION: Unlike intravenous ondansetron, oral ondansetron is not superior to metoclopramide for the prevention of nausea and vomiting caused by strabismus surgery in children.

[Prevention of postoperative nausea and vomiting by lorazepam].

This study was carried out to assess the efficacy of oral lorazepam on postoperative nausea and vomiting in patients undergoing thyroid surgery. Twenty-six patients were randomly assigned to two groups, and receiving orally, one hour before induction of anaesthesia, either 2.5 mg of lorazepam (n = 13) or a placebo (n = 13). Lorazepam reduced the incidence and especially the intensity of nausea. The incidence of vomiting in the lorazepam group was significantly lower than in the placebo group (14.5% vs 45%). The use of lorazepam for premedication thus reduces the incidence of postoperative nausea and vomiting. The advantages of this benzodiazepine are its ease of use, low cost and very low incidence of side effects.

[Subcapsular hematoma of the liver. Six cases and review of the literature].

Defined as a blood collection under the Glisson capsule, the subcapsular haematoma of liver is a rare complication of pre-eclampsia. We observed 6 cases of subcapsular haematoma of the liver in the Gynaecology-Obstetrics ward of the Ibnou Rochd University Hospital in Casablanca, Morocco. Age range was 18 to 39 years. Five of the patients were multiparous. All except one had at least one sign of pre-eclampsia. The diagnosis was made post-partum in 5 cases and was only confirmed intra-operatively in 6 cases. The treatment was tamponing-drainage of the peritoneal cavity in 3 cases, ligature of the hepatic artery in 2, and in one case with rupture of the liver, no therapy could be performed. There were 3 maternal deaths and 2 foetal deaths. These results were compared with those in the literature to determine the epidemiologic, diagnostic, therapeutic and prognostic characteristics of the subcapsular haematoma of the liver. The prognosis is poor and requires early diagnosis and treatment. Effective prevention of this severe complication should be based on correct screening and care for pregnant patients with hypertension.

[Fatal hepatic necrosis during treatment with sodium valproate].

The authors report a case of fatal hepatic failure in a 19-year old young man suffering from absence seizures and treated for two months with valproic acid (VPA). The duration of VPA therapy before onset of clinical manifestations was four weeks. The prodromal symptoms were weakness, anorexia, and vomiting, then in a few weeks occurred a jaundice and an hepatic encephalopathy leading to death. Among laboratory findings disturbance of liver tests and particularly depressed levels of clotting factors were observed. The histologic study of the liver showed an extended centrolobular necrosis associated with fatty change and fibrosis. The mechanism of this hepatic failure remains unknown. The seriousness of this complication necessitates to respect any contraindications.

[Neurologic manifestations of fat embolism].

Neurologic manifestations are usual and variable during post-traumatic fat embolism. The pathogenesis of these lesions continues to be a source of considerable controversy. Thirteen cases of post-traumatic fat embolism with neurologic signs were treated in a surgical intensive care unit. All patients had impaired consciousness. Focal neurologic disorders were reported in 5 cases [hemiplegia (2), tetraplegia (2), aphasia (1)]. The aspects on brain CT scan seemed to be related to ischemic lesions (1 case), appeared normal in ten cases, or revealed post-traumatic hemorrhagic lesions (2 cases). The outcome at 2-4 weeks was spontaneously good, with complete resolution, without neurologic sequellae, in 11/13 patients. Two deaths were related to brain trauma severity (one case) and nosocomial pneumonia (one case).

[Thrombosis of the right atrium disclosed by severe pulmonary embolism].

The case of a thrombosis of the right auricle, revealed by severe pulmonary embolism in a 56-year-old patient without significant medical history is reported. He was admitted to the ICU with a haemorrhagic cerebrovascular accident. The course was characterized by the occurrence of a venous thrombosis of the right lower limb confirmed by phlebography. The treatment with a platelet antiaggregating agent was effective and the patient left hospital two weeks later. He was re-admitted after 2 months with a clinical picture of massive embolism including polypnea, tachycardia and haemoptysis. The diagnosis was confirmed by pulmonary angiography (Miller index > 65%) and echocardiography showed a floating thrombus in the right auricle with dilated right cavities. The phlebocavography displayed an extensive thrombosis in the left lower limb up to femoral, iliac and cava inferior veins. The patient was treated with heparin (500 IU.kg-1.d-1) and later with antivitamine K. The course was favourable. This is a rare case of extensive thrombosis, completely regressive with a treatment including only heparin.

[Tetraplegia in fat embolism].

This is a report of two cases of tetraplegia complicating fat embolism after fracture of long bones. In the first case, a 26 year-old male sustained fractures of femur and tibia. One day after admission, the patient became comatose (Glasgow coma score = 6) with dyspnaea and petechiae present on the anterior chest wall. In second case, a 22 year-old man with a fracture of tibia and humerus, suffered two days after admission from similar signs of fat embolism (dyspnaea, Glasgow score coma = 6, petechiae). A tetraplegia occurred after 7 days in the first patient and 6 days in the second. No lesions were visible on brain CT scan. Magnetic resonance imaging showed relative high-intensity areas on T2 weighted views. The outcome at three weeks was favourable, without neurologic sequelae.
