Sudden unexpected nocturnal death syndrome (SUNDS) is a distinct clinical entity in previously healthy, young, Southeast Asian males. It is well known in the Philippines and more recently recognized in the U.S. by nonspecific autopsy findings, with no evidence of underlying disease and absence of toxic drug or alcohol levels. In 1973-89, 14 cases of apparent SUNDS came to coroner's autopsy in the Commonwealth of the Northern Marianas (CNMI) and Guam. All 14 cases, with the exception of one Yapese, were previously healthy, male Filipinos, aged 23 to 55, who were either found dead in bed, or described by their colleagues as having nocturnal seizure activity consisting of gurgling, frothing, and tongue biting immediately prior to death. Autopsy findings showed no anatomic findings to account for death. Comprehensive serum and urine drug analyses were negative. All decedents showed absence of significant atherosclerosis or grossly detectable structural cardiac anomaly, while four showed cardiomegaly. Migrants from Southeast Asia carry with them a pre-disposition to this syndrome, which appears to decline with longer residence in the new country. The mechanism of death in SUNDS is believed to be ventricular fibrillation, possibly precipitated by sudden sympathetic discharge. Studies suggest at least some deaths may be associated with an abnormal cardiac conduction system. Acute pancreatitis has been a finding in some series, but not our cases. Why the condition is virtually limited to males and seemingly sleep-triggered, has not been adequately explained. Stress and depression are believed to be predisposing factors. 相似文献

Microbiologic analysis of different soil samples was undertaken to assess the value of this method for forensic purposes. Three groups of micro-organisms were isolated on selective media: bacteria, fungi, and actinomycetes. Comparison of the morphology of the colonies led to the conclusion of non identity of the soil samples under examination. The method was applied to soil traces on articles of clothing, trousers, shoes, and stockings. It was found that the soil did not originate from the suspected scene of a crime. Examination of the microbiologic soil composition does not provide an absolute certainty of identity, but it is highly reliable. 相似文献

State and federal funds are important sources of revenue for medical schools, and a strong case can be made for public support for these institutions. Although the federal role is more widely known, the states in fact provide the bulk of direct support for medical training. The nature of aid from the two sources differs in significant ways. Most federal aid supports research or patient care, but much of state aid goes to support unconditional tuition subsidies. The primary beneficiaries of these subsidies are relatively affluent nonminority students who are beginning lucrative careers in the medical field--careers that would be lucrative even if no subsidies were provided. Nor does it appear that general subsidies are needed to attract poor and minority applicants. While targeted loans and scholarships to individuals may be justified, general tuition subsidies are not. 相似文献

Sudden and unexpected death and violent death of persons with a high risk of acquiring HIV-infections, especially homosexual males and intravenous drug abusers, have to be investigated by forensic autopsies. Therefore every forensic pathologist has to be aware of this infection and should try to make the proper diagnosis. Three typical cases are described: (1) suicide by hanging, (2) homicide by cutting the throat and (3) intravenous heroin overdose. Merely retrospectively it could be cleared up that the deceased were homosexual but did not manifestly suffer from AIDS. The morphological findings in the lymph nodes and the postmortem serological findings are described in detail. 相似文献
