RESUMO
Childhood and adolescent suicides have been increasing worldwide in recent years, and the investigation of such deaths is often complex. Forensic pathologists frequently find themselves having to opine as to the manner of death in these difficult cases. The present study was undertaken to identify distinguishing features in childhood and adolescent suicides to assist in the investigation and prevention of these deaths. A 25-year review of pediatric suicides in a metropolitan area was performed, which showed a steady increase in pediatric suicides over time. Male pediatric suicides were more common than female, with both having an average age of 15 years. Gunshots wounds and hanging were the most common methodologies seen, with drug toxicity being more common in females and gunshot wounds more common in males. Approximately 20% of decedents had a psychiatric history, 25% had a previous history of a suicide attempt or ideation, and 24% had a history of drug use. Only a minority of decedents made their intentions known prior to the suicidal act (16%) or left a note of intent (16%). In 62% of cases, a temporal, precipitating event could be identified, of which conflict with a significant other (boyfriend or girlfriend) was the most common. No specific trends over time were identified. While these features may assist forensic pathologists in assessing a possible suicidal death in the pediatric age group, medicolegal death investigators must approach these deaths as they would any violent death in an attempt to accurately determine the manner of death regardless of the societal and familial implications of such a determination.

It is essential that clinical physicians, medical personnel, medical examiners, and law enforcement agencies understand the types of injuries seen and demographics of children affected by intentional blunt force as this understanding can be crucial to the death and/or criminal investigations. An understanding of the injuries can also assist in drawing conclusions regarding how those injuries could have been sustained. This study discusses the types and patterns of injuries seen in blunt force homicides in children younger than 6 years. The study found that male infants are more often intentionally injured than are female infants and that fatal head injuries most frequently occur in the first year of life, whereas most fatal thoracoabdominal injuries occur in the first 3 years of life. In children with head injuries, subdural hemorrhage was the most common finding, followed by subarachnoid hemorrhage. In 2.5% of deaths due to head injury, concurrent neck injury was seen, a percentage far lower than previous literature would suggest if shaking was the primary mechanism of injury. Twelve legal confessions were also reviewed, none of which disclosed a pure mechanism of shaking the infant.

A 19-year-old G1P0 Caucasian woman died 8 days postpartum because of the subinvolution of the uteroplacental arteries. Microscopic examination of the placental implantation site revealed large, dilated spiral arteries containing partially occluding thrombi in the superficial myometrium. The presence of cytotrophoblasts within and surrounding the spiral arteries was confirmed by low molecular weight cytokeratin immunohistochemistry. Infection of the Cesarean section incision site was demonstrated by the growth of Staphylococcus aureus and Streptococcus agalactiae Group B in the wound as well as the intrauterine blood clot. Although subinvolution of the placental site may be a cause of delayed postpartum hemorrhage and significant morbidity, the underlying pathophysiologic mechanism is unknown.
