An Approach to the Classification of Apparent Asphyxial Infant Deaths.

Recent evidence indicates that with thorough, high quality death investigations and autopsies, forensic pathologists have recognized that many unexpected infant deaths are, in fact, asphyxial in nature. With this recognition has come a commensurate decrease in, and in some cases, abolition of, the label "sudden infant death syndrome" (SIDS). Current controversies often pertain to how and why some infant deaths are determined to be asphyxial in nature and whether or not apparent asphyxial circumstances are risk factors for SIDS, or rather, harbingers of asphyxial deaths.

Recommendations for the Autopsy of an Infant who has Died Suddenly and Unexpectedly.

As the result of improved death scene investigations and the performance of more thorough and thoughtful pediatric forensic autopsies, there has been a widespread increase in the recognition of asphyxial mechanisms of death as well as lethal natural diseases that might have otherwise been erroneously labeled as sudden infant death syndrome (SIDS) or sudden unexpected infant death (SUID). Although it is fair to state that "more thorough autopsies provide more thorough medical evidence" from which to draw upon when determining cause and manner of death, there is no standard, accepted baseline from which forensic pathologists operate. Although anatomic pathologists are quite accustomed to practicing within well-defined boundaries for specimen (and thus diagnostic) adequacy, forensic pathologists are frequently hesitant to embrace or adopt such concepts.

Pathologic evaluation of the cervical spine following surgical and chiropractic interventions.

When patients die after chiropractic or surgical interventions of the cervical spine, pathologists tasked with the autopsy are frequently overwhelmed by the complicated anatomy, laborious dissections, complex operative procedures and surgical hardware, and the necessity to differentiate artifacts from trauma and disease. However, abundant data can be obtained from careful evaluation of the cervical spine in situ; extensive postmortem diagnostic imaging procedures; detailed dissections of the removed, formalin-fixed and decalcified spine; and histology. This study presents a regimented, stepwise approach to the evaluation of the cervical spine in these difficult cases, promotes uniform assessment, facilitates diagnoses, and supports the accumulation of otherwise hard-to-come-by reference material that can be of value in future cases.

"Grown-up" congenital heart disease and sudden death in a medical examiner's population.

Despite advances in the management of congenital heart disease (CHD), children with CHD who survive into adulthood are at increased risk of sudden death. Sudden death may also be the initial presentation of undiagnosed CHD in some adults. This retrospective descriptive study outlines the spectrum of CHD presenting as sudden death in adults in a medical examiner's population.

Two-handed cardiopulmonary resuscitation can cause rib fractures in infants.

The discovery of acute rib fractures in deceased infants and young children can be unsettling. Although significant injuries may occur subsequent to resuscitative efforts in adults, it is well documented that such injuries are rare in much younger individuals. In particular, it is considered exceptional for rib fractures to follow cardiopulmonary resuscitation (CPR) on an infant; thus, some pathologists will consider such a discovery to be evidence of abuse.

Homicide by unspecified means.

The fundamental function of all North American systems of death investigation is to determine cause and manner of death. Modern teaching emphasizes the need to consider all investigative aspects including careful evaluation of the scene and circumstances, history, physical examination of the body, and ancillary laboratory studies, prior to death certification. This integrative approach to forensic pathology differs from an autopsy-focused practice whose function is to produce "anatomic" cause of death statements.

Do resuscitation-related injuries kill infants and children?

Occasionally, individuals accused of inflicting fatal injuries on infants and young children will claim some variant of the "CPR defense," that is, they attribute the cause of injuries found at autopsy to their "untrained" resuscitative efforts. A 10-year (1994-2003) historical fixed cohort study of all pediatric forensic autopsies at the Miami-Dade County Medical Examiner Department was undertaken. To be eligible for inclusion in the study, children had to have died of atraumatic causes, with or without resuscitative efforts (N(atraumatic) = 546).

Sulfuric acid injury.

Injuries and deaths from exposure to caustic substances are infrequently reported in the forensic pathology literature. Strong acids like sulfuric acid produce a predictable set of injuries with cutaneous exposure and ingestion. Multiple factors influence the resultant pathology, but from the perspective of the autopsy pathologist, the most important is the length of postingestion survival.
