The purpose of this study was to determine if it is possible to associate machetes, axes, and cleavers with the microscopic parallel striations they leave on the cut surfaces of the bone. Hacking trauma was experimentally inflicted on pig bones using machetes, axes, and cleavers. Negative impressions of both the cut surfaces of the bone and the weapon(More)
The presence and location of ocular hemorrhages were prospectively studied in 169 randomly selected child deaths referred to a medical examiner. Causes of death in the study group included natural diseases and various injuries involving the head, trunk, and asphyxia. Retinal hemorrhages were identified in 70 cases: 62 head injuries, four central nervous(More)
Blood alcohol (ethanol) concentrations in decomposed bodies can mean drinking during life and/or endogenous production after death. The correct interpretation is important in medicolegal cases. This retrospective study of 286 autopsied medical examiner cases was undertaken to evaluate alcohol concentrations and distribution in various fluids and tissues in(More)
The pathophysiology of perimacular folds in eyes of deliberately traumatized children is disputed. The authors reviewed the clinical and forensic records and systemic and ocular findings at autopsy of three children with perimacular retinal folds who died after being violently shaken. Two of the children suffered direct head trauma in addition to being(More)
Death certificates are important because morbidity and mortality statistics often come from death-certification data. These statistics are vital in developing approaches to disease treatment and strategies for increasing longevity. It is often the primary care physician who is responsible for completing the death certificate, for explaining the cause of(More)
These studies were conducted to evaluate effects of high dose norepinephrine infusion on left ventricular function in anesthetized and conscious dogs. Separate groups of pentobarbital anesthetized closed-chest dogs received norepinephrine infusion for 90 min followed by 1 h of recovery. Arterial pressure, electrocardiogram, two-dimensional echocardiogram(More)
Forensic pathologists are frequently asked to describe the interval between injury and the onset of symptoms in child abuse head injury deaths. A prospective, postmortem study examined the interval between injury and onset of symptoms in 76 head injury deaths in which this information was available. The head injury deaths were divided by mechanism of(More)
An adolescent is reported with type 1 diabetes mellitus and diabetic ketoacidemia (DKA) who died from brain herniation prior to treatment with intravenous fluids and intravenous insulin. The pathophysiology of raised intracranial pressure (ICP) and water intoxication is discussed. As DKA evolves, water and electrolyte losses are replaced by very hypotonic(More)
Postmortem examination is a cornerstone in identifying the cause of unexplained sudden death in children. Even in cases of suspected or known abuse, an autopsy may help characterize the nature of the abuse, which is particularly important in the forensic autopsy of children in the first 3 to 4 years of life when inflicted neurotrauma is most common.(More)
