Glamorizing sick bodies: how commercial advertising has changed the representation of HIV/AIDS

As a consequence of pharmaceutical advancements, HIV is no longer described in terms of the absence of health or presence of illness, and advertisements promoting anti-AIDS medications commercialize idealized and desirable bodies. The present study discusses representations of HIV/AIDS in commercial advertising and their change over time. The article traces the shift in AIDS/HIV representations in commercial advertising from the early 1990s, when images of decay and disease represented AIDS, to nowadays, when the wider availability of antiretroviral medications and their ability to prolong life produced new representations of HIV-afflicted bodies. Claiming that HIV individuals can lead a normal life where everything is possible, advertising has re-established the definition of a sick body. On the other hand, this marketing approach has important social implications because such representations minimize the seriousness of HIV infection and fail to take into account the real dangers of contracting HIV and to accurately represent the life with HIV and AIDS.     

Sudden Unexpected Death Due to Graves' Disease During Physical Altercation

We report a case of a 30‐year‐old woman who suddenly collapsed after having a physical altercation with her husband. Despite immediate resuscitation, she died on arrival at the hospital. The victim's parents requested an autopsy because they believed that their daughter was killed by her husband. Postmortem examination revealed that the victim had a diffusely enlarged thyroid gland and cardiomegaly with left ventricular hypertrophy. There was no evidence of significant trauma on the body. Further postmortem thyroid function tests and review of her medical history indicated that her death was due to Graves' disease. To the best of our knowledge, this is the first case reported of sudden death due to cardiac arrhythmia from Graves' disease induced by physical and emotional stress associated with the criminal activity of another person. The autopsy findings are described. In addition, the literature is reviewed and the significance of postmortem evaluation of thyroid hormones in the cases of sudden death is discussed.     

Carbon Monoxide Poisoning and Death in a Large Enclosed Ventilated Area

A 55‐year‐old man with a medical history of tobacco use suddenly collapsed while power washing an empty indoor pool in a hotel. The decedent was transported to the local hospital where he was pronounced. A postmortem examination revealed atherosclerotic heart disease and bilateral pulmonary edema and congestion. A postmortem blood carbon monoxide (CO) level was 27% saturation, and a CO performed on hospital admission blood was 49% saturation. CO poisoning is a common cause of toxicological morbidity and mortality in the United States. The circumstances most often occur in an enclosed environment and may be intentional or unintentional. CO poisoning has been reported in open, well‐ventilated spaces, but rarely results in death. A warning label was present on the engine clearly stating the dangers of CO emission. However, there was a false sense of security due to the large size of the pool room and the presence of industrial blowers that were being used for ventilation.     

GFP标记的重组新城疫病毒HN基因乳酸菌表达载体的构建及原核表达

为构建具有示踪特性的新城疫病毒(NDV)HN基因乳酸菌穿梭表达载体,采用PCR方法扩增NDV HN基因与绿色荧光蛋白(GFP)基因,将两基因克隆至乳酸菌表达载体pW425et中,转化入表达宿主菌BL21(DE3)后利用IPTG诱导表达。用荧光显微镜检查重组菌的绿色荧光效应,采用SDS-PAGE和Western-blotting检测其在大肠杆菌中的表达情况。结果显示,NDV HN和GFP基因与表达载体pW425et正确重组。荧光显微镜下可见阳性重组菌落的绿色荧光,且该重组菌传代30代次以上,荧光效应依然稳定。SDS-PAGE显示表达出约63ku的条带,与已知表达的HN蛋白大小相符。Western-blotting进一步证实该蛋白能被NDV阳性血清所识别,具有反应原性。构建了GFP标记的重组NDV HN基因乳酸菌穿梭表达载体且能在大肠杆菌中表达。     

职业病鉴定制度的“诉讼化”改革

现行职业病鉴定制度具有＂仿诉讼化＂的特点,但仍然在公正性、便民性、权利性和救济性等方面存在一定的制度弊端,今后需要沿着＂诉讼化＂方向深化改革,切实保障劳动者公正获取职业病诊断和鉴定的权利。     

An Analysis of The Morbidity and Mortality of Diabetes Mellitus in a Forensic Context

To investigate the spectrum of diseases seen in diabetes mellitus in a forensic context, all autopsy reports of diabetic individuals who presented to Forensic Science, South Australia (FSSA), over a 5‐year period from 2005 to 2009 were studied. The leading cause of death was cardiovascular disease (55.0%), followed by unnatural deaths (15.4%) and infections (9.4%). In type 1 diabetics, principal causes of death included cardiovascular disease (44.7%), acute metabolic complications (18.7%), unnatural deaths (17.9%), and infections (8.9%). However, frequencies of these diseases differed in type 2 diabetics, with cardiovascular events responsible for 56.6% of cases, followed by unnatural deaths (15.0%) and infections (10.9%). A larger number of male deaths were seen in all disease categories, except respiratory and gastrointestinal where the frequencies were similar to females. Cardiovascular disease was the leading overall cause of death across all ages except in those under the age of 30 where metabolic complications were more common.     

Ebstein Anomaly and Sudden Childhood Death

A 13‐year‐old girl is reported who died suddenly and unexpectedly in her sleep from previously undiagnosed Ebstein anomaly. At autopsy, there was dilatation of the right atrium with marked dilatation of the right auricle and apical displacement of the tricuspid valve into the right ventricular cavity with atrialization of the upper portion of the right ventricle. There were also prominent dysplastic changes in both the septal and posterior leaflets of the tricuspid valve with thickening of the valve and fusion of leaflets to the wall of the ventricle. Histology of the myocardium showed focal, minor microscopic areas of interstitial fibrosis with marked fibrous dysplasia and thickening of the tricuspid valve. Lethal arrhythmias occur in this condition because of the geographical relationship of the conduction system to the abnormal anatomical structures. As adolescents who died suddenly are often minimally symptomatic, cases will rarely present de novo to forensic autopsy.

Involvement of Amphetamines in Sudden and Unexpected Death

Abstract:  In the present study, the effects of amphetamine-class drugs were examined in cases reported to the Victorian coroner from 2001 to 2005 to determine if death can occur from the use of amphetamine-class drugs alone. A total of 169 cases were reviewed where a forensic autopsy detected amphetamine(s) in the blood. Pathology, toxicology, and police reports were analyzed in all cases to ascertain the involvement of amphetamine-class drugs in these deaths. In Victoria, methamphetamine (MA) is the principal abused amphetamine-class followed by methylenedioxymethamphetamine (MDMA). There were six cases in which a cerebral hemorrhage caused death and three cases in which serotonin syndrome was established as being caused by the interaction of MDMA and moclobemide. There were 19 cases in which long-term use of amphetamines was associated with heart disease. There were three cases where amphetamine-class drugs alone were regarded as the cause of death, of which two cases exhibited high levels of MDMA and lesser amounts of MA and/or amphetamine. There were no cases in which significant natural disease was absent and death was regarded as caused by the use of MA. There was no correlation between blood concentration of drug and outcome.     

连接蛋白43与心性猝死的相关性研究进展

部分心性猝死者死后尸检时心脏没有发现明显病理学异常征象,过去均将其归属原因不明的猝死范畴。近年来研究显示,心肌连接蛋白43（connexin43,Cx43）表达对于心性猝死的诊断具有十分重要的意义。本文就Cx43结构、功能以及在心血管疾病发生发展中的作用与法医学意义作一综述。
