Sudden unexplained death in the young poses a diagnostically challenging situation for practicing autopsy pathologists, especially in the absence of anatomic and toxicological findings. Postmortem genetic testing may identify pathogenic variants in the deceased of such cases, including those associated with arrhythmogenic channelopathies and cardiomyopathies. The Wisconsin State Laboratory of Hygiene (WSLH) is a state-run public health laboratory which performs postmortem genetic testing at no cost to Wisconsin medical examiners and coroners. The current study examines sequencing data from 18 deceased patients (ages 2 months to 49 years, 5 females) submitted to WSLH, from 2016 to 2021. Panel-based analysis was performed on 10 cases, and whole exome sequencing was performed on the most recent 8 cases. Genetic variants were identified in 14 of 18 decedents (77.8%), including 7 with pathogenic or likely pathogenic variants (38.9%). Whole exome sequencing was more likely to yield a positive result, more variants per decedent, and a larger number of variants of uncertain significance. While panel-based testing may offer definitive pathogenic variants in some cases, less frequent variants may be excluded. Whole exome testing may identify rare variants missed by panels, but increased yield of variants of uncertain significance may be difficult to interpret. Postmortem genetic testing in young decedents of sudden unexplained death can provide invaluable information to autopsy pathologists to establish accurate cause and manner of death and to decedent's relatives to allow appropriate management. A public health laboratory model may be a financially advisable alternative to commercial laboratories for medical examiner's/coroner's offices. 相似文献

The correlation of childhood physical abuse history and later abuse in a group of Turkish population
Caykoylu A Ibiloglu AO Taner Y Potas N Taner E 《Journal of interpersonal violence》2011,26(17):3455-3475
Domestic violence is passed from one generation to the next, and it affects not only the victim but also the psychological states of the witnesses, and especially the psychosocial development of children. Studies have reported that those who have been the victim of or witnessing violence during their childhood will use violence to a greater extent as adults in their own families. This research examines the relationships between a history of childhood physical abuse, likelihood of psychiatric diagnoses, and potential for being a perpetrator of childhood physical abuse in adulthood among women who received psychiatric treatment and in the healthy population from Turkey. Estimates of the prevalence of childhood physical abuse vary depending on definition and setting. The frequency of witnessing and undergoing physical abuse within the family during childhood is much higher in the psychiatrically disordered group than the healthy controls. Childhood physical abuse history is one of the major risk factors for being an abuser in adulthood. The best indicator of physically abusing one's own children was found to be as physical abuse during the childhood period rather than psychiatric diagnosis. There is a large body of research indicating that adults who have been abused as children are more likely to abuse their own children than adults without this history. This is an important study from the point of view that consequences of violence can span generations. Further studies with different risk factor and populations will help to identify different dimensions of the problem. 相似文献

The medicolegal death investigation system in the Kingdom of Saudi Arabia (KSA) is unique in the world. It is exclusively derived from Islamic judiciary based on Shari'ah law, which is the definitive Islamic law or doctrine. This law is applied on Saudi citizens as well as foreigners. This is different from other Islamic countries, which have a combination of Islamic and other judiciary systems.The forensic medicine centers in KSA are related administratively to the Ministry of Health (MOH) and its subdivisions in the different governorates. They are concerned with forensic medical examination and autopsy, as well as the clinical forensic medical examination of sexual assault cases, and those injured in civil and criminal cases. The assisting laboratories (forensic histopathology, microbiology, serology, forensic chemistry) are working independently under the funding of MOH, whereas the DNA laboratory and other departments of forensic sciences, for example, counterfeiting and forgery unit are related administratively to the Ministry of Interior represented by the Administration of Criminal Evidences. Efforts concerning crime scene investigations are shared with Administration of Criminal Evidences' crime scene investigators.Forensic medicine education in KSA developed in the past few years after the foundation of Saudi specialty certificate in forensic medicine. The certificate is a postgraduation qualification equivalent to a doctorate degree in forensic medicine and requires completion of a 4-year training program in both MOH- and Ministry of Interior-related departments, as well as passing annual evaluation and examination.This review is aimed at providing in the next decade the medicolegal centers with national forensic specialists throughout the kingdom and granting skillful headships for the next generations. Moreover, this review suggests more scientific associations with the academic universities in the various fields of forensic sciences through academic cooperation. 相似文献

Hypernatremia has been causally linked with subdural hematoma (SDH), but more recently this has been called into question. Conversely, there is a well-established link between SDH and injury. We wish to examine the evidence base that hypernatremia in infants and young children causes SDH.We present 2 cases of children with severe hypernatremia whose intracranial contents were assessed by imaging in the first case and postmortem examination in the second. Neither demonstrated SDH. The first case was important as the hypernatremia was iatrogenic occurring in a controlled hospital environment.We also searched the literature from 1950 to 2007, collecting data on all reported cases of hypernatremia in children younger than 7 years whose intracranial contents were examined by imaging, surgery, and/or postmortem examination. Of 124 cases reported in 31 articles, 112 cases developed hypernatremia in the community, and 12 in the hospital. Subdural hematoma was demonstrated in 7 cases, all of which had developed hypernatremia in the community under circumstances that would make it difficult to exclude nonaccidental injury. None of the 12 cases that developed hypernatremia in a controlled hospital environment had SDH.The evidence base supporting the hypothesis that hypernatremia causes SDH is poor, depending on isolated reports with uncertain histories. 相似文献

In this study fifty samples of crystalline methamphetamine obtained from antinarcotics police of Iran seized during the year 2010 were analyzed. In order to determine the chemical characteristics of these samples, anion test, Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS) were carried out on the samples. All of the samples containing methamphetamine tested positive for chloride anion. The range of methamphetamine hydrochloride content in these samples was 33-95%. One sample out of 50 contained no methamphetamine. The fact that 1,2-dimethyl-3-phenylaziridine was the most frequently found impurity in the analyzed samples, indicates that most of the methamphetamine samples seized in Iran have been synthesized from pseudoephedrine as starting material. 相似文献

Terrorism in Pakistan springs from many factors such as, poverty, corruption, inequality, sham democracy, and low-level literacy; however, the effect of terrorism in India over terrorism in Pakistan remains unnoticed. This study explores the role of terrorism in India as a determinant of terrorism in Pakistan. This fangled determinant of terrorism in Pakistan forms the premise of our work. The Johansen cointegration analysis technique confirms the long-run relationship among terrorism in India and Pakistan and unemployment in Pakistan. Error correction model (ECM) resulted 55% of convergence annually. Besides, ECM verifies both short and long-run causalities. The VECM Granger and Modified Wald (MWALD) causality tests reveal that terrorism in India and unemployment in Pakistan Granger causes terrorism in Pakistan, but no reverse causality exists. The study concludes that both terrorism in India and unemployment in Pakistan results in terrorism in Pakistan. Coping with terrorism, Pakistan and India must revisit their respective roles; and simultaneously, Pakistan should address the unemployment problem—which facilitates recruitment for the terrorist organizations. 相似文献
