Nerium oleander is an ornamental evergreen shrub belonging to the family Apocynaceae. The Apocynaceae family includes the attractive evergreen shrub known as oleander. The cardiotoxic glycoside, oleandrin, is present in all portions of the common oleander plant. Oleander consumption can result in deadly situations accidentally or as a suicide attempt. After consuming kettle-boiled oleander leaf extract as part of a suicide attempt, an 80-year-old man was discovered comatose in his home and taken to our emergency room. The patient's heart rate was 30 beats per minute, and he had hypotension. Arterial blood gas analysis revealed remarkable metabolic acidosis and hyperkalemia (K: 7.7 mEq/L). An electrocardiogram showed a wide QRS wave, similar to a sine curve. The patient collapsed following cardiac arrest soon after hospital arrival. Veno-arterial extracorporeal membrane oxygenation was initiated; however, the patient eventually died. The serum level of oleandrin at hospital arrival, subsequently measured by LC–MS/MS, was found to be 33.4 ng/mL, far above the levels reported in previous fatal cases. 相似文献

Given a current total incidence of erroneously administered blood transfusions of 1:12,000-1:36,000 (AB0 incompatible 1:38,000), the percentage of lethal outcomes ranges between 2 and 5%; i.e. the sole fact of an erroneous transfusion does not mandatorily result in a causal connection with lethal outcome, which can give rise to problems in the medicolegal assessment. We report on the conception and results of a novel interdisciplinary approach to assess the lethal significance of blood transfusion errors. Besides autopsy, histological investigation and immunohistochemical detection of AB0 incompatible foreign red blood cells in autopsy specimens, transfusion medicine investigations offer the opportunity to assess several immunohaematologic features. We assessed the immunohaematologic gel card ("microcolumn") technique for suitability in the forensic assessment of an AB0 incompatible transfusion incident in a septic patient, who had had no history of previous blood transfusions, with lethal outcome. After such an erroneous transfusion had been simulated in vitro, pre-transfusion and cadaver patient blood samples (p.m. interval: 3 days) were analysed. Amongst other things, IgG-loaded erythrocytes were detected in pre- and post-transfusion samples; the presence of irregular antibodies directed against blood group antigens and anti-A or anti-B isoagglutinins, respectively, especially in the pre-transfusion sample was ruled out. Besides the demonstration of AB0 incompatible red blood cells in the cadaver blood sample, blood group incompatibilities other than AB0 were excluded. With regard to the cause of death, in synopsis with autopsy findings and clinical symptoms, the results did not allow for a final discrimination between the impact of the pre-existing septic inflammatory response syndrome and sepsis, respectively, and potential lethal effects of a (haemolytic) transfusion reaction. Besides pre- and post-transfusion compatibility testing in clinical transfusion medicine as required by German National Guidelines, the reported immunohaematologic investigations offer an important supportive tool for the forensic assessment of lethal erroneous transfusions and investigation of blood samples of survivors of transfusion incidents as well. Besides established morphological techniques, they allow for a certain evaluation of the pathophysiological impact of transfusion incidents as well as a diversified assessment of immunohaematologic features beyond the AB0 system. 相似文献

Sudden infant death syndrome (SIDS)--standardised investigations and classification: recommendations 总被引:2,自引:0,他引:2
Bajanowski T Vege A Byard RW Krous HF Arnestad M Bachs L Banner J Blair PS Borthne A Dettmeyer R Fleming P Gaustad P Gregersen M Grøgaard J Holter E Isaksen CV Jorgensen JV de Lange C Madea B Moore I Morland J Opdal SH Råsten-Almqvist P Schlaud M Sidebotham P Skullerud K Stoltenburg-Didinger G Stray-Pedersen A Sveum L Rognum TO 《Forensic science international》2007,165(2-3):129-143
Sudden infant death syndrome (SIDS) still accounts for considerable numbers of unexpected infant deaths in many countries. While numerous theories have been advanced to explain these events, it is increasingly clear that this group of infant deaths results from the complex interaction of a variety of heritable and idiosyncratic endogenous factors interacting with exogenous factors. This has been elegantly summarised in the "three hit" or "triple risk" model. Contradictions and lack of consistencies in the literature have arisen from diverse autopsy approaches, variable applications of diagnostic criteria and inconsistent use of definitions. An approach to sudden infant death is outlined with discussion of appropriate tissue sampling, ancillary investigations and the use of controls in research projects. Standardisation of infant death investigations with the application of uniform definitions and protocols will ensure optimal investigation of individual cases and enable international comparisons of trends. 相似文献

Population studies were carried out on the Y-specific short tandem repeat (STR) systems DYS19, DYS389I + II, DYS390 and DYS393 in a Western German population sample. Determination of the allele frequencies revealed for all these systems, unimodal distribution. The number of observed alleles varied: five for DYS19, six for DYS390, three for DYS389I, seven for DYS389II and six for DYS393. In 102 unrelated male individuals, 56 different haplotypes were found. The haplotype diversity values were similar to those of other European populations. 相似文献

A multicentre retrospective analysis of 4450 autopsies carried out due to suspicion of medical malpractice in 17 German institutes of forensic medicine from 1990 to 2000 was performed for the German Federal Ministry of Health. During the time period analysed an increase of cases could be mentioned. The main results of the study are: in the cooperating institutes the total number of autopsies due to suspected medical malpractice ranged from 1.4 to 20%. In more than 40% of the cases preliminary proceedings were started because the manner of death was certified as non-natural or not clarified. Hospital doctors were more affected by medical malpractice claims than doctors in private practice. However, the number of confirmed cases of medical malpractice was higher for doctors in private practice than for hospital doctors. Although surgery is still at the top of the disciplines involved in medical malpractice claims the number of confirmed surgical cases was below the average. Mistakes in care were confirmed to be above the average. Medico-legal autopsies are still a very sufficient method to evaluate cases of medical malpractice: 2863 cases could already be clarified by autopsy. Up to now there is no systematic registration of medical malpractice charges in Germany. A systematic registration should be initiated to build up and/or improve error reporting systems and, thus, to improve patient safety. Compared to other sources of medical malpractice claims (arbitration committees of the medical chambers, reference material of health and insurance companies, files of civil courts) the data of the present multicentre study are in so far unique as only lethal cases were evaluated and a complete autopsy report was available as basis of an expert opinion in alleged medical malpractice cases. 相似文献

For several decades vitreous humor has been used for post-mortem biochemical investigations with the objective of a post-mortem diagnosis of pre-existing diseases and the clarification of forensic issues, in particular the determination of the post-mortem interval. For the determination of measured concentrations in vitreous humor pre-analytic factors as well as analytical and instrumental variations have to be taken into consideration. The aim of this study was a methodical investigation of two methods of sample pre-treatment as influencing variables. The compared methods were centrifugation and treatment in the ultrasonic bath. The determined parameters were sodium, potassium, chloride, calcium, lactate, urea, glucose and creatinine. Analyses were performed photometrically or by an ion-selective electrode. For some of the analytes a dilution was necessary before analysing. Regarding to the two pre-treatment methods, significant differences in the measured concentrations were not found. The precision proved to be mostly unsatisfying and was clearly better in diluted samples than in undiluted aliquots. A comparison of the vitreous humor of the two ocular bulbs did not lead to significant differences. 相似文献

A 56 year old man was found suspended in a sack in a head down position. Circumstances and autopsy findings are discussed. The leading pathophysiological mechanisms causing death are thought to be asphyxia due to compression of the chest and insufficient blood supply to the heart due to the head down position. The pathophysiological dysregulation of circulation in a head down position is discussed. 相似文献

The different statements concerning the slope and intercept of the regression line and the 95% limits of confidence are the reason that potassium in vitreous humor is not used (at least in Germany) as an aid in estimating the time of death. The relationship between the concentration of potassium and the time of death is mainly influenced by antemortem electrolyte imbalances caused by disease and/or duration of terminal episode. The influence of terminal episode is best identified by its duration (Adelson et al., J. Forensic Sci., 8 (1963) 503-514). In order to have a method suitable for every case and to be as precise as possible we looked therefore for parameters in vitreous humor which were stable postmortem and indicating antemortem electrolyte imbalance. Urea is such a parameter, being stable postmortem (Coe, Am. J. Clin. Pathol, 51 (1969) 741-750) and useful as a marker of antemortem electrolyte imbalance. Our investigations on potassium in vitreous humor, including sudden and hospital deaths after chronic lingering disease, revealed 95% limits of confidence of +/- 34 h up to 120 h postmortem. Reviewing only cases with urea less than 100 mg/dl the 95% limits of confidence could be reduced to +/- 22 h. Considering the duration of terminal episode (less than 6 h) the precision was +/- 20 h. In this way our modified procedure is suitable for every case with the resulting precision of estimation being determined only by the duration of the terminal episode and urea concentration. 相似文献

Pheochromocytomas are known to be rare causes of sudden death. A 49-year-old man with a medical history of arterial hypertension and diabetes mellitus complained about nausea and malaise in the morning. During the day his condition deteriorated. He went to the emergency department, where he was given intravenous drugs against nausea and was sent home. On the way back, his condition deteriorated dramatically so that his wife drove back to the emergency room, where he collapsed and sustained cardiac arrest; resuscitation efforts were unsuccessful. Autopsy revealed a large tumour of the left adrenal gland. The strong suspicion of pheochromocytoma was confirmed by histology, immunohistochemistry and biochemical investigations. An acute hypertensive crisis, caused by the hitherto unknown pheochromocytoma was ascertained as the cause of death. The morphological findings are presented, the difficulty to diagnose pheochromocytoma and the medico-legal implications are discussed. 相似文献
