[Justification of routine puncture of ascites in cirrhotic patients admitted to emergency hospital units].

OBJECTIVES: Spontaneous bacterial peritonitis (SBP) is a frequent, serious, recurrent complication, occurring in 10 to 30% of cirrhotic patients hospitalized with ascites. The key to diagnosis of SBP is ascites paracentesis and polymorphonuclear count in ascitic fluid. The purpose of our study was to evaluate sensitivity and specificity of clinical and biological criteria in diagnosis of 5 BP. METHODS: We prospectively reviewed 30 adult cirrhotic patients admitted in our emergency department with ascites. Ascites paracentesis was performed in each patient, and SBP diagnosis was based on either positive bacteriological culture or polymorphonuclear count above 250/mm3 in ascitic fluid. Classical criteria for SBP were recorded: blood pressure under 90 mm of Hg, abdominal pain, temperature above 38.5 or under 36.5, jaundice, encephalopathy, increased serum bilirubin or creatinine, leukocyte blood count about 12 G/l. We evaluated sensitivity and specificity of those criteria in SBP, and compared their frequency in patients with SBP or sterile ascitic fluid. RESULTS: Thirty patients were included in our series, and in 14 of them a SBP was diagnosed. A significant difference was observed between spontaneous bacterial peritonitis and sterile ascitic fluid for abdominal pain and temperature abnormalities, but specificity and sensitivity of these criteria were very low. Moreover, SBP was asymptomatic in 7%. CONCLUSION: Due to the high rate of mortality in patients with SBP we recommend diagnostic procedures for this frequent complication as soon as patient is admitted in emergency department. This diagnosis must be based on ascitic fluid paracentesis, which has to be performed, in the emergency department, in every cirrhotic patient admitted with ascites. Indeed, SBP is often asymptomatic, and no clinical or bacteriological criteria can be considered as completely reliable for the diagnosis of spontaneous bacterial peritonitis.

Adult first generalized seizure: etiology, biological tests, EEG, CT scan, in an ED.

The purpose of this study was to evaluate adult first seizures in an emergency department by analyzing etiologic and epidemiological data and studying the usefulness of biological screening, electroencephalogram (EEG), and cerebral computed tomography (CT) scan. This was a retrospective study of a 3-year period during which 247 patients were admitted to an emergency department for a first generalized seizure. A CT scan had been performed in 247 patients and an EEG in 209. Etiologies were found to be (1) unknown, (2) alcohol abuse, (3) stroke, and (4) tumor. Early recurrence rate was 18.5%. EEG was of low interest in emergency. The rate of cerebral focal lesions on CT scan was significantly lower when both examination results and EEG were normal. The rate of metabolic abnormalities was 4.9%. It was concluded that (1) a short hospitalization is advisable because of recurrences, (2) recurrence rate does not increase significantly in patients with focal cerebral lesion, (3) metabolic screening is necessary, and (4) CT scan will be an outpatient procedure for most patients.

[Entomophthoromycoses in Madagascar (three cases)].

The authors present three new cases of Entomophthoromycosis observed in Madagascar: Two cases of subcutaneous entomophthoromycosis without isolation of germ. An immunofluorescence technique showed the Basidiobolus ranarum to be the real cause. One case of rhinoentomophthoromycosis with isolation of Conidiobolus coronatus (first isolation in Madagascar).

[Paradoxical embolism of the aortic arch diagnosed by transesophageal echocardiography. Surgical treatment].

The authors report the case of a woman who presented with a pulmonary embolism followed by systemic embolism. Transoesophageal echocardiography showed a persistent foramen ovale compatible with a possible paradoxical embolism. In addition, a mobile embolism in the aortic arch was demonstrated. This embolism was extracted under cardiopulmonary bypass to avoid a recurrence of embolism. Transoesophageal echocardiography is the only reliable, non-invasive method allowing simultaneous diagnosis of a right to left shunt and visualisation of the thoracic aorta.

[Bepridil and torsades de pointes: are the precautions of use respected?].

The torsades de pointes with bepridil are serious side-effects, known right from 1982, and for which definite therapeutic recommendations were decreed in 1984 then in 1991. The observations of 7 new cases drove us to discuss about the respect for these recommendations. From the study of these 7 middle-aged patients (+/- esm) 76.9 +/- 2.4, we have noticed that they all combined 3 risk-factors at least with an average (+/- esm) 3.71 +/- 0.29 (range 3-5). The non-respect for the methods of prescription of bepridil leads to serious trouble in the rate of heartbeat and can threaten vital prognosis. So, it is advisable for the practicians to be warmly and precisely informed and prescribe another anti-angina-pectoris treatment in high risk-patients.
