Autologous Bone Flap Resorption Years After Subtemporal Craniotomy
In Spring of 2012, the partially undressed and skeletonized remains of a homeless adult Hispanic male was found in a fairly open wooded area in Nebraska. The remains showed evidence of extensive pathologies, which included healed traumas and surgeries. Examination of the decedent\u27s medical records revealed that he had a history of kidney and liver problems, alcohol abuse, several traumas including a major head injury that necessitated a craniotomy, and radiological features of neurocysticercosis. The autologous bone flap, which was replaced after the craniotomy, had resorbed significantly away from the edges of the injury. Death was variously attributed to craniocerebral injury with hypothermia sequel to blunt force trauma most probably due to a fall. The manner of death was ruled as an accident. This study makes use of the forensic evidence and medical records to examine the possibility that the unique combination of failed cranioplasty, hypothermia, and neurocysticercosis may have contributed to the victim\u27s death. Other potential causes of death are considered

Four postmortem case reports with quantitative detection of the synthetic cannabinoid, 5F-PB-22.
In January 2014, the US government temporarily designated 5F-PB-22, along with three other synthetic cannabinoids (AB-FUBINACA, ADB-PINACA and PB-22), into Schedule I. Over the course of a 4-month time period (July-October 2013), our laboratory quantitatively identified 5F-PB-22 in specimens obtained from four postmortem cases. We describe the four cases, to include pertinent autopsy findings and decedent histories, together with quantitative results for 5F-PB-22 determined in postmortem blood and antemortem serum. Samples were prepared via a liquid-liquid extraction at pH 10.2 into hexane : ethyl acetate. Instrumental analysis was achieved with liquid chromatography coupled with electrospray ionization tandem mass spectrometry operating in multiple reaction monitoring mode. Two ion transitions were monitored for the analyte of interest, and one ion transition was monitored for the internal standard. The observed concentration range of 5F-PB-22 is 1.1-1.5 ng/mL for three postmortem blood specimens and one antemortem serum specimen. Three of the decedents experienced abrupt, sudden death; however, one decedent expired after a rapidly deteriorating hospital course
