Organ Weight Reference Ranges for Ages 0 to 12 Years.

Abnormal organ weights often serve as an indicator of underlying disease or other pathological process making assessment of organ weight a critical part of the autopsy examination and interpretation. Unfortunately, normal organ weights for children are often based on studies done in the 1930s and 1960s. Thus, the present study was designed to accurately assess organ weights in children to establish reference ranges for use in autopsy examinations. A total of 1759 traumatic deaths in children aged 0 to 12 years were reviewed. Analysis revealed that body length was the best predictor for organ weight. Reference ranges were established and stratified by both age and body length.

Primary breast lymphoma with sudden death.

Primary breast lymphoma is a rare form of extranodal lymphoma. B cells constitute the most common type involving the breast. T cells represents only 3%. Even though lymphomas have a high predilection to metastasize to the heart, there are no specific clinical or radiological findings, and most of the cases are diagnosed at autopsy. We discuss the case of a 49-year-old woman with primary breast lymphoma who presented with sudden death. Autopsy revealed a primary T-cell lymphoma of the breast with tumoral infiltration of the atrioventricular node and transmural myocardial permeation with focal necrosis.

Evaluation of Concordance Between Original Death Certifications and an Expert Panel Process in the Determination of Sudden Unexplained Death in Childhood.

Importance: The true incidence of sudden unexplained death in childhood (SUDC), already the fifth leading category of death among toddlers by current US Centers for Disease Control and Prevention estimates, is potentially veiled by the varied certification processes by medicolegal investigative offices across the United States. Objective: To evaluate the frequency of SUDC incidence, understand its epidemiology, and assess the consistency of death certification among medical examiner and coroner offices in the US death investigation system. Design, Setting, and Participants: In this case series, 2 of 13 forensic pathologists (FPs) conducted masked reviews of 100 cases enrolled in the SUDC Registry and Research Collaborative (SUDCRRC). Children who died aged 11 months to 18 years from 36 US states, Canada, and the United Kingdom had been posthumously enrolled in the SUDCRRC by family members from 2014 to 2017. Comprehensive data from medicolegal investigative offices, clinical offices, and family members were reviewed. Data analysis was conducted from December 2014 to June 2020. Main Outcomes and Measures: Certified cause of death (COD) characterized as explained (accidental or natural) or unexplained, as determined by SUDCRRC masked review process. Results: In this study of 100 cases of SUDC (mean [SD] age, 32.1 [31.8] months; 58 [58.0%] boys; 82 [82.0%] White children; 92 [92.0%] from the United States), the original pathologist certified 43 cases (43.0%) as explained COD and 57 (57.0%) as unexplained COD. The SUDCRRC review process led to the following certifications: 16 (16.0%) were explained, 7 (7.0%) were undetermined because of insufficient data, and 77 (77.0%) were unexplained. Experts disagreed with the original COD in 40 cases (40.0%). These data suggest that SUDC incidence is higher than the current Centers for Disease Control and Prevention estimate (ie, 392 deaths in 2018). Conclusions and Relevance: To our knowledge, this is the first comprehensive masked forensic pathology review process of sudden unexpected pediatric deaths, and it suggests that SUDC may often go unrecognized in US death investigations. Some unexpected pediatric deaths may be erroneously attributed to a natural or accidental COD, negatively affecting surveillance, research, public health funding, and medical care of surviving family members. To further address the challenges of accurate and consistent death certification in SUDC, future studies are warranted.
