Accidental Deaths Involving Trees: Professional and Nonprofessional Woodcutting and Tree Failures With Autopsy Findings.

ABSTRACT: We examined all deaths in Connecticut involving tree mishaps (struck by a tree/tree limb, injuries associated with tree removal operations). Records of the Connecticut Office of the Chief Medical Examiner including autopsy, toxicology, and investigators' reports of deaths from 2004 to 2019 were reviewed. All underwent autopsy examination.There were 64 fatalities, with ages ranging from 4 to 90 years (mean, 50 years). The causes of death involved the following: 56 blunt injury (primary site: 25 head, 13 multiple locations, 11 torso, and 7 neck), 5 traumatic asphyxia, 2 electrocution, and 1 chainsaw injury. Deaths were classified into 3 groups: 21 nonprofessional woodcutters, 19 professional woodcutters, and 24 tree failures. Among all woodcutters (100% men), impact by a falling tree/limb (78%) was the most common fatal event, and the most common lethal injury site was the head (45%). For tree failures, 58% involved storm/high-wind events, whereas 42% were spontaneous. Of the tree failure events, 58% involved motor vehicles, with most (86%) occurring while driving. Ethanol was detected in 6 decedents with blood concentrations ranging from 0.02 to 0.19 gm%, of which 4 were nonprofessional and 2 were professional woodcutters. There were some seasonal differences among the 3 groups.Overall, fatalities of nonprofessional woodcutters, compared with professionals, were more likely to involve an older man (58 vs 40 years), working alone (67% vs 11%), and under the influence of ethanol (19% vs 11%) in late summer-autumn who dies of blunt head trauma from a falling tree or tree limb. Aggressive tree control management along highways has been used to attempt to decrease storm-related fatalities.

Right Ventricle Rupture After Open Heart Surgery.

The potential complications of cardiac surgery with sternotomy include mediastinitis and major bleeding, events that are infrequent but carry high mortality.We report a unique complication of median sternotomy. A 71-year-old man underwent coronary artery bypass grafting complicated by sternal dehiscence on postoperative day 7. One week after discharge, he presented with purulent drainage from the sternal wound bed and was diagnosed as having mediastinitis. Irrigation, debridement, and sternal reconstruction were performed. Two days later, bleeding was observed in the wound, and during surgical exploration, a tear in the right ventricle was discovered, and the patient exsanguinated and died. Autopsy findings included focal adhesions connecting the posterior sternum to the right ventricle wall, as well as microscopic evidence of focally extensive fatty infiltration along the rupture margin of the myocardium.Pertinent aspects of the case are reviewed, with particular attention to the possible microbial etiology of mediastinal infection and most likely mechanisms of injury contributing to the fatal right ventricular rupture.

Comorbid Mental Disorders in Fetal Alcohol Spectrum Disorders: A Systematic Review.

OBJECTIVE: A systematic review of published literature to estimate prevalence of comorbid mental disorders in fetal alcohol spectrum disorders (FASDs) and compare with general population prevalence estimates. METHODS: A PubMed search was used to locate articles reporting on FASD and mental disorders published through June 2015. Next, lists of published studies from all issues of the National Organisation for Foetal Alcohol Syndrome-UK publication Fetal Alcohol Forum-were searched. Weighted average prevalence was estimated for the comorbid mental disorders with sufficient data for analysis. We then compared prevalence of mental disorders in the FASD population with rates in the mental health literature. RESULTS: We identified 26 articles reporting 5984 cases of FASD. Of the 15 comorbid mental disorders, 11 had sufficient data for inclusion in the analysis. Attention-deficit/hyperactivity disorder occurred in 50% of persons with FASD (10 times the expected rate). Intellectual disability occurred at 23 times the expected rate. In 5 of the 12 disorders, rates in the FASD population significantly exceeded expected rates by 10% to 45%. CONCLUSION: Increased rates of mental disorders in people with FASD are commonly reported. Mental health providers should routinely consider FASD in the diagnosis and management of mental illness and developmental disorders. The quality of the research and precision of comorbidity estimates would be improved by additional studies including people with FASD and non-FASD comparison subjects. Until these studies are available, this review provides the best available estimates of comorbid mental disorders in people with FASD.
