[Hematemesis disclosing hemorrhagic fever with renal syndrome].

We report a case of hematemesis as the presenting sign of hemorrhagic fever with renal syndrome. Gastroscopy revealed hemorrhagic gastropathy. Such lesions are a common finding in epidemic nephropathy, the European form of the disease. The occurrence of such lesions could be induced in a direct, cytopathic effect of the virus but seems also to be related to the severity of thrombocytopenia.

Intubating conditions and neuromuscular effects of mivacurium during propofol-alfentanil anaesthesia.

In three groups of 20 patients, anaesthetized with propofol and alfentanil, tracheal intubation conditions and the onset of neuromuscular blockade after administration of three different doses of mivacurium chloride (0.11, 0.15, and 0.19 mg/kg = 1.5 x ED95, 2 x ED95, and 2.5 x ED95) were assessed. Intubation conditions were found to be clinically acceptable (good or excellent) in 83% of patients. Eighty-two per cent of patients were successfully intubated on the first attempt after 60-90 s. No difference in intubation scores or number of intubation attempts among the three dosage groups were found. We conclude that mivacurium chloride allows smooth intubation in most patients within 60-90 s, even with the lowest dose (0.11 mg/kg), after a propofol-alfentanil induction of anaesthesia. However, because there were a few patients in whom intubating conditions were inadequate at 60-90 s, we are reluctant to advocate the preference of mivacurium chloride over suxamethonium for rapid sequence induction in emergency situations.

[Association of pseudochylothorax and pleural tuberculosis. Apropos of a case].

The authors report a case of pseudochylothorax revealed by pleural tuberculosis. Classically, pseudochylothorax is a late complication of chronical and calcified pleurisy especially sequellae of tuberculosis treated by induced pneumothorax. Treatment consist on thoracentesis or aspiration with frequent remove. Surgical decortication can be useful. Specific chemotherapy is only necessary in the patients in whom tuberculosis is present or never treated with antibiotics.

[Duplex Doppler ultrasonography of intra-renal arteries. Normal and pathological aspects].

Duplex Doppler ultrasonography may explore renal perfusion in frequent diseases such as renal obstruction, reno-vascular hypertension, acute or chronic renal failure or diabetic renal complications by measuring Pourcelot's resistive index (RI) of renal parenchyma arteries for each kidney. A statistical and prospective study was performed on 574 patients. In healthy patients, the RI values, equal for each kidney were included in 0.45 and 0.7 (mean RI = 0.59). For other values, there was a renal pathology. Patients with idiopathic hypertension (mean RI = 0.59) or non obstructive dilatation (mean RI = 0.61) did not have an RI significantly different from healthy patients. In cases of renal obstruction, there was a significant increase in the RI for the pathological kidney (mean RI of 0.73). The sensitivity and the specificity was 100% for acute obstructions examined during the first 48 hours. In contrast, in case of renal artery stenosis greater than 70% there was a significant decrease in the RI for pathological kidney. So the RI increased significantly in both kidneys: when there was renal failure with active disease within the tubulo-interstitial compartment (mean RI of 0.77); in all cases of diabetic nephropathy (mean RI of 0.74) where the RI increased early before laboratory signs. Duplex Doppler ultrasonography may be an original method for renal explorations by providing not only morphological data but also physiological data with the perfusion study.
