ABSTRACT
We report a case of fatal sodium poisoning due to the unintentional use of 20% hypertonic saline serum during peritoneal lavage after intestinal resection. The patient presented with unconsciousness, metabolic acidosis, and plasma sodium concentration of 193 mE/l. After 3 hours, he developed paroxysmal supraventricular tachycardia, hyperthermia, generalized tonic-clonic convulsions, disseminated intravascular coagulation, and adult respiratory distress syndrome. The patient died 15 hours after the operation. Pathological examination revealed cerebral and lung oedema, pericentral hepatic necrosis, and fibrin thrombi in the lungs, stomach, and kidneys. We review, in addition, other reported cases of sodium poisoning.

We report a case of fatal weeverfish sting. An 18-year-old man was stung on the left leg by a weeverfish, which he was attempting to capture while snorkelling off the coast of Majorca (Spain). The man felt intense pain, but managed to swim to his boat where he lost consciousness after boarding rapidly. An hour later, when examined by a doctor, the subject was found to be in cardiorespiratory arrest. Reanimation manoeuvres were unsuccessful. The most import post-mortem findings were in the skin and lungs. A puncture wound, which traversed the greater saphenous vein and was covered by an intense haemorrhagic infiltrate, was observed in the skin. The lungs showed haemorrhagic alveolar oedema.

Intestinal ischemia induced by cocaine abuse is a rare condition. To this date, only three cases have been described. The diagnosis of bowel ischemia should be suspected whenever a cocaine addict has severe abdominal pain. A pathological examination of the resected bowel segment was performed in one case, and the diagnosis was confirmed microscopically. However, the existence of pathologic alterations of the intestinal vessels was not confirmed. Why the intestinal injury is segmental and whether it is related to the dose ingested, the administration route, or the combination of cocaine with alcohol, caffeine, or marijuana remain unclear. The authors report one fatal case associated with cocaine-alcohol overdose. The postmortem examination demonstrated the existence of segmental intestinal ischemia. Microscopic study failed to demonstrate thrombosis in the mesenteric vessels; however, we found an unusual lesion affecting the arterioles located in the intestinal submucosa of the hemorrhagic areas.

We report a case of suicide following ingestion of a large dose of 3,4-methylenedioxyethamphetamine (MDEA, "Eve") in a 27-year-old woman with a history of depression. Several days before her death, she had attempted suicide with benzodiazepines resulting in a 24-hour hospital admission; at that time, no physiologic abnormalities were detected. Findings on autopsy were nonspecific. Toxicologic analysis showed a high concentration of MDEA and the appearance of benzodiazepines in body fluids. Ethanol and other drugs of abuse were not found. We discuss the clinical manifestations, toxicologic syndromes, and mechanisms of death with amphetamine intoxication. MDEA intoxication in young people may result in sudden death.

A 66-year-old-male patient with a history of depression voluntarily ingested around 400 ml of an insecticide composed of 5% methylparathion, 75% isoparaffin, 8% etoxylated oleic acid, 4% 1,2,4-trimethylbenzene, 6% naphtha, 1% 1,3,5- trimethylbenzene, 0.4% propylbenzene and 0.3% xylene. The patient was conscious and alert at admission. Gastric lavage was performed and activated charcoal administered. There were no clinical symptoms of organophospate ingestion despite reduced concentrations of erythrocyte and plasma cholinesterase. Chest X-ray showed pulmonary infiltrate compatible with bronco-aspiration. The patient evolved to respiratory failure refractory to treatment and died from multiorganic failure 23 days after ingesting the insecticide. The pathological findings included a pulmonary fibrosis in the alveolar spaces which caused enlargement of the intra-alveolar septa. Abundant lipin-laden macrophages were observed within the alveolar spaces. We review the most relevant aspects of cases of fatal lipoid pneumonia and point out that on occasion severe or fatal intoxication is due to the substances accompanying the active ingredients.
