Over the past several years, Medical Examiners in Kentucky and around the nation have observed a dramatic rise in drug intoxication deaths involving the prescription medication methadone. This documented rise in methadone-related deaths requires a better understanding of methadone's pathophysiology and the ways it contributes to significantly increase morbidity and mortality. This study reviews 176 fatalities ascribed to methadone toxicity by the Office of the Chief Medical Examiner in Kentucky between 2000 and 2004. Postmortem toxicological analysis recorded a more than 10-fold increase in methadone toxicity fatalities, rising from 6 cases in 2000 to 68 cases in 2003. Of the 176 methadone-related fatalities, methadone was the only drug detected in postmortem blood and urine toxicological analyses in 11 (6.25%) cases. The mean methadone blood concentration of all 176 cases was 0.535 mg / L (0.02-4.0). The following psychoactive medications were detected: antidepressants (39.8%), benzodiazepines (32.4%), and other opioids in addition to methadone (27.8%). Cannabinoids were detected in 44 (28.4%) cases and cocaine or metabolite in 34 (21.9%) cases. Of the 95 cases with a known history of methadone use, 46 (48.4%) involved prescription by private physician. The interpretation of blood methadone concentrations alone or combined with other psychoactive drugs requires consideration of the subject's potential chronic use of and tolerance to the drug. A thorough investigation into the practices of procurement and use/abuse of methadone is essential to arrive at the proper designation of the cause of death.

The risk of suicide is significantly increased in schizophrenics; it is estimated that 10-13% of individuals suffering from schizophrenia commit suicide. Schizophrenia is marked by psychotic exacerbations and remissions, with persistent deterioration in baseline functioning with each relapse. We present a 10-year (1993-2002) retrospective review of Medical Examiners' cases of suicide of schizophrenic victims. Twenty-nine cases were between the ages of 20 and 75 (mean age of 41.6 years). The majority of victims were male (62.1%) and Caucasian (86.2%). The leading method of suicide for both males and females was firearm injury (48.3%) mostly of the head, followed by overdose (20.7%), and hanging (13.8%). A comprehensive investigation of the biopsychosocial factors is warranted in cases of schizophrenics who commit suicide. This study offers an insightful analysis pertaining to the determination of intent in formulating the manner of death in this unique population.

Ehlers-Danlos syndrome (EDS) type IV is a connective tissue disorder characterized by the inability to produce sufficient amounts of collagen or a defect in the structure of collagen. The most serious complications include a rupture of a viscus or vascular rupture with or without mural dissection. Death may result from internal hemorrhage. This report describes three cases of sudden and unexpected death caused by EDS type IV. Two cases involved hemothorax as a result of dissection of the subclavian artery and aorta, respectively. The third case represented spontaneous pulmonary rupture and hemorrhage. A detailed family history should be sought, and additional specimens collected to confirm the diagnosis, including skin fibroblasts for collagen testing and blood for DNA testing. The forensic pathologist should consider the possibility of EDS type IV upon discovery of spontaneous visceral or arterial rupture and should alert the family members of this hereditary and potentially fatal condition.

The compilation of all suicidal causes of death attained the third highest ranking of mortality between the ages of 15 and 24 following unintentional deaths and homicide in the United States, accounting for approximately 4000 deaths in 2002. A variety of biopsychosocial factors may contribute to adolescent suicidal behavior, including psychiatric disorders, risk-taking behaviors, and lack of a cohesive family unit. The authors conducted a 10-year (1993-2002) retrospective review of 108 Medical Examiner cases of suicide ages 11-17 and 358 cases ages 18-24 in Kentucky, which represents two thirds of the Coroner cases in the state. The majority of victims were male and Caucasian. The major causes of death were the same for the two age groups, specifically, firearm injury (72.2% and 70.7%), hanging (22.2% and 18.7%), and drug intoxication (2.8% and 5.3%). An integrated Coroner-Medical Examiner system profits in the public health arena by providing collaborative research data for policy decisions. The prevalence of youth suicide by firearm should prompt further discussion regarding ways to better identify high-risk adolescents and young adults and restrict pediatric access to unsecured household firearms.

Excited delirium denotes a life-threatening medical condition characterized by the acute onset of agitated and violent behavior that often results in a sudden and unexplained death. Cocaine-induced excited delirium refers to fatal cocaine intoxication with the following symptoms occurring sequentially: hyperthermia, delirium with agitation, respiratory arrest, and death. We present a case of cocaine-induced excited delirium in a cocaine "body packer" or a "mule", specifically an individual who attempts to smuggle cocaine within the body. Investigators at the scene initially suspected homicide due to the victim's sharp and blunt force injuries. Three rubber packets containing cocaine were removed from the victim's rectum. Blood toxicological analysis revealed an alcohol concentration of 0.016 g/100 and cocaine >1 mg/L. The forensic pathologist should consider cocaine-induced excited delirium when an individual exhibits aggressive behavior, unexpected strength, and resistance to pain who dies suddenly. Further analysis should be performed during the scene investigation and autopsy for evidence of body packing.
