[Acute poisoning caused by hydrogen sulphide: clinical features of 3 cases].

We describe three cases of acute intoxication by hydrogen sulphide which were produced after remaining between 50 and 60 minutes inside a cellulose tank. The three patients had loss of conscience. One of the patients developed a persistent vegetative state; another patient recovered although with neurological post-anoxic sequelas and the third case completely recovered one week after his hospitalization. The patients underwent symptomatic treatment and the environmental concentrations of hydrogen sulphide were measured at the site of the accident. Finally, the application of preventive measures is stressed.

Value of differential quantitative blood cultures in the diagnosis of catheter-related sepsis.

A prospective study was performed to assess the value of differential quantitative blood cultures in the diagnosis of catheter-related sepsis when this condition is suspected on clinical grounds and to establish a reliable discriminative value for application without removal of the inserted catheter. A total of 107 central venous catheters from 64 patients were used for the study. Blood was obtained simultaneously through the suspected infected device and from a peripheral venipuncture. The catheter was removed and its tip cultured semiquantitatively. Catheter-related sepsis occurred in 17 patients. Using as cut-off value a colony count fourfold higher in blood drawn through the catheter than in simultaneously drawn peripheral blood, a sensitivity of 94%, specificity of 100% and positive predictive value of 100% were obtained. A single bacterial count greater than 100 cfu/ml in the quantitative culture of the catheter blood specimen in the presence of a positive qualitative peripheral blood culture of the same organism was also highly suggestive of catheter-related sepsis. Differential quantitative blood culture is a reliable method for the diagnosis of catheter-associated sepsis without catheter removal.

[Snake bites in our environment. A biannual review of 7 cases].

The clinical picture, treatment and evolution of seven patients presenting snake bites are analyzed. Local symptoms were constant, with a spontaneous favorable evolution in 7 to 10 days. The most relevant systemic manifestations were coagulation anomalies which appeared in two patients. Treatment always included local wound care, antitetanicum antibiotic and anticoagulant prophylaxis with specific antiophidic serum in five patients.

[Paraquat poisoning: clinical and anatomopathologic aspects in 3 cases].

3 cases of suicide due to ingestion of 150, 200 and 4 gr. of paraquat, respectively, are presented. Two of them were brothers and agricultural industrialists, the other one was a farmer. The first two cases died 16 and 10 hours after intake. The farmer died 21 days after ingestion. All of them had progressive hypoxemia and renal failure the two brothers had heart conduction system glycemia (23 mg/dl) a few hours after ingestion. The postmortem study showed edema, hemorrhage and congestion of the lungs, alveolitis, fibrosis and lobar atelectasia; renal tubular necrosis adrenal necrosis; colestasia; hepatic steatosis focal miocarditis. The clinical evolution, particularly short in the first two patients, is commented on, as well as the post-mortem findings, comparing them with those described in the literature. Finally, due to the high toxicity of this herbicide, we insist in prompt transport to herbicide, we insist in prompt transport to the hospital in order to apply early treatment.
