Homicide by organophosphorus compound poisoning: a case report.

Pesticides are responsible for less than 1% of deaths from poisoning in the UK while various studies in India indicate that the figures range from 20% to a staggering 70% (Sharma, 1998). Organophosphorus compounds are reported to be the most commonly used substances for suicidal purposes (Dixit, 2007). Homicidal poisoning involving pesticides has always been rare owing to the disagreeable odour and taste rendered to them by their hydrocarbon solvents (Pillay, 2008). An unusual case of homicide using an organophosphorus compound is presented here. The body of a 28-year-old woman was brought for post-mortem examination at the mortuary of the Government Medical College and New Civil Hospital, Surat, Gujarat, India. It had been exhumed after forty-five days of burial under the supervision of a medical officer from the nearby primary health centre, the police and a magistrate. There was a history of marital discord between the deceased and her husband. Their ten-year-old daughter, who was the only witness to the incident, revealed later that her mother was struck by a wooden block and forcibly made to ingest some medicine. The 'medicine' was identified on chemical analysis as an organophosphorus compound (dichlorvos).

Fatal venous air embolism following intravenous infusion.

Venous air embolism has been reported as a complication of invasive diagnostic and therapeutic procedures or accidental trauma. Little is known about the incidence of air embolism after minimal intravenous manipulations such as the insertion of a peripheral intravenous cannula. Only when large amounts of air sufficient enough to block the cardiovascular system enter, the patient develops symptoms and signs of severe neurological injury, cardiovascular collapse, or death. The dead body of a 14-year-old boy was brought for postmortem examination with allegations of death from negligence during treatment. He was treated for pain in the abdomen in a hospital by attendants in telephonic consultation with a medical practitioner. Following intravenous infusions, the boy died suddenly in respiratory distress. Gross findings indicated the death to be from venous air embolism. Chemical analysis, histopathology, and microbiology ruled out other causes of death. Dilemmas of the case with difficulties in diagnosis are being presented herewith.
