Deaths related to chemical burns.

The authors present a series of 6 deaths due to the uncommon cause of chemical burns. Of the 6 deaths due to chemical burns, 4 deaths were due to ingestion of a chemical, 1 death was caused by chemical burns of the skin, and 1 death resulted from rectal insufflation of a chemical. Seven additional cases where chemical burns may have been a contributing factor to the death or an incidental finding are also presented.

Death of a 6-month-old due to a tracheal bronchus.

The death of an infant younger than 1 year requires a thorough scene investigation and autopsy. Most infant deaths investigated by forensic pathologists can be placed into 2 general categories: sudden infant death syndrome and accidental asphyxial deaths. Despite the fact that most infant deaths occur within these 2 categories, it is important to remember that other entities may be responsible for death.

Autopsy diagnosis of fat embolism syndrome.

The fat embolism syndrome (FES) is considered a clinical diagnosis. It typically occurs within several days following major traumatic injury, usually involving fractures of the pelvis and/or lower extremities. Fat embolism syndrome is characterized by the onset of respiratory, neurological, cutaneous, and hematologic manifestations and is thought to be related to intravascular embolization of fat, presumably arising from within the fractured bone marrow space.

Case study: Asphyxia caused by inspissated oral and nasopharyngeal secretions.

An institutionalized man with severe mental disability and cerebral palsy, admitted from the ED with suspected aspiration pneumonia, died after a long struggle with respiratory difficulties. The cause of death was determined to be asphyxia resulting from a complete obstruction of the posterior pharynx and upper larynx by thickened oral and nasopharyngeal secretions. Although airway obstruction is common in people with motor or neurologic disorders and in those who are chronically debilitated or institutionalized, food and foreign matter are not the only culprits.

Hate crimes and the forensic pathologist.

Hate crimes represent crimes committed against an individual or group on the basis of their race, ethnicity, national origin, religion, sexual orientation, gender, gender identity, or disability. For the forensic pathologist, a death related to a hate crime should be considered a high-profile case, one in which the pathologist should expect abundant public interest and scrutiny. In this article, an overview of hate crimes is presented, stressing the different types of hate crimes and the motives of those who commit such crimes.
