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. ⋯ 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.

In the present study, the effects of amphetamine-class drugs were examined in cases reported to the Victorian coroner from 2001 to 2005 to determine if death can occur from the use of amphetamine-class drugs alone. A total of 169 cases were reviewed where a forensic autopsy detected amphetamine(s) in the blood. Pathology, toxicology, and police reports were analyzed in all cases to ascertain the involvement of amphetamine-class drugs in these deaths. ⋯ There were three cases where amphetamine-class drugs alone were regarded as the cause of death, of which two cases exhibited high levels of MDMA and lesser amounts of MA and/or amphetamine. There were no cases in which significant natural disease was absent and death was regarded as caused by the use of MA. There was no correlation between blood concentration of drug and outcome.

An autopsy examination is important in identifying the cause of death and as a means of auditing clinical and forensic practice; however, especially in perinatal and infantile age groups determining the cause of death leads to some difficulties in autopsy practice. In this study, 15,640 autopsies recorded during the years 2000-2004 in the Mortuary Department of the Council of Forensic Medicine were reviewed. Autopsy findings of 510 cases between 20 completed weeks of gestation and 1 year of age were analyzed retrospectively. ⋯ According to their ages, the cases were subdivided into three groups. Intrauterine deaths were 31% (158 cases), neonatal deaths were 24% (123 cases), and infantile deaths were 45% (229 cases) of all cases. Scores for the quality of the necropsy report were above the minimum acceptable score with 44% in intrauterine, 88% in neonatal and infantile deaths.

Perforations of both esophagus and aorta after swallowing foreign bodies have been described, with aorto-esophageal fistulas at the level of the descending aorta or aortic arch. We present the case of a 48-year-old man with esophageal perforation by fish bone, mediastinitis, and evidence of perforation of the ascending aorta during surgical drainage of the mediastinum. At autopsy, a fish bone was found under the aortic arch. ⋯ Direct demonstration of the perforation of the posterior wall of ascending aorta was provided. Histological examination ascribed aortic perforation to migration of the fish bone and direct injury. This is the first anatomical and pathological study of an autopsy case of perforation of the ascending aorta by fish bone.

Traumatic brain injury is the leading cause of morbidity and mortality among children suspected of child abuse. Penetrating cranio-facial injuries are generally rare in the pediatric age group and are caused by both accidental and inflicted mechanisms. We report an unusual case of a 2-year-old female who was admitted to a pediatric emergency room with an industrial stainless steel coat hanger impaled in her skull. Pertinent clinical forensic medicine examination, coupled with home inspection and interviews by the local law enforcement, revealed a horrible episode of domestic violence.
