Case ReportsCocaine intoxication: hyperpyrexia, rhabdomyolysis and acute renal failure.
Cocaine has become the recreational drug of abuse of the eighties. The prevalence of cocaine has been manifesting increases in intoxications and poisonings. ⋯ Treatment consisted of cooling via iced intravenous fluids, nasogastric lavage with ice water, and benzodiazepine sedation. To our knowledge, there is no case report which supports the allusions that cocaine intoxication may cause rhabdomyolysis and acute renal failure.

Case ReportsRepeated hemoperfusion and continuous arteriovenous hemofiltration in a paraquat poisoned patient.
Prompt hemodialysis or hemoperfusion can be of value during the first 24 hours after paraquat ingestion particularly when the patient has developed acute renal failure. However, many cases of paraquat poisoning occur in areas where hemoperfusion facilities are unavailable. In contrast, continuous arteriovenous hemofiltration (CAVH) could be instituted easily. ⋯ The mean hemoperfusion clearance of paraquat was 50 ml/min and the total amount of paraquat removed by the 34 hours of hemoperfusion was 9 mg. Because of the relative ease with which CAVH can be performed, its low cost, compared to that of hemoperfusion or hemodialysis, and the continuous nature of the procedure, CAVH may be worth considering in paraquat poisoning. It could be used particularly in those patients who have developed renal failure or while patients are being prepared for hemoperfusion.

In three patients with severe acute cyanide poisoning, a cyanosis was observed instead of the bright pink skin coloration often mentioned as a sign in textbooks. Treatment of cardiopulmonary insufficiency is as essential as antidotal therapy and the use of sodium nitrite and 4-DMAP is not without risk as, in practice, the methemoglobin-level induced is difficult to control.

Case ReportsNitrite/thiosulfate treated acute cyanide poisoning: estimated kinetics after antidote.
A 34 year old, 73 kg man ingested a 1 gram potassium cyanide pellet in a suicide attempt. Within one hour, coma, apnea, metabolic acidosis, and seizures developed. Sodium nitrite and sodium thiosulfate were administered. ⋯ Serial whole blood cyanide levels were obtained, documenting a highest measured level of 15.68 mcg/mL. Estimations of toxicokinetic parameters including terminal half-life (t 1/2) (19 hours), clearance (163 mL/minute), and volume of distribution (Vd) (0.41 L/kg) were calculated. The nitrite/thiosulfate combination was clinically efficacious in this case and resulted in complete recovery.
