Brain weight in completed suicide and other cases of death-comparison of recent and previous studies.

BACKGROUND: The weight of human brains is subject of numerous scientific research studies particularly in anatomy, pathology, and forensic medicine. Just a few investigations deal with a possible correlation between psychiatric disorders, especially suicidality, and brain weight. The results are contradictory. AIMS: This study aims to find out if postmortem brain weight is higher in suicide victims considering the discrepancies of previous studies. METHOD: In a retrospective study, the weight of brains obtained by autopsies performed in the Institute of Legal Medicine in Frankfurt, Germany, was evaluated. Data of 99 suicide cases (64 males, 35 females) were compared with those obtained from similar number cases of sudden death in a matched pair analysis. In each case, body weight, height, and body mass index were also taken into account. RESULTS: No significant differences in brain weight were found in suicide victims compared to those of the control group. CONCLUSIONS: The brain weight depends on various parameters such as gender, age, body height, and weight. The selection criteria for suicide cases as well as for the corresponding control population are essential in evaluating the brain weight in suicide.

Accidental mechanical asphyxia of children in Germany between 2000 and 2008.

Accidents constitute one of the greatest risks to children, yet there are few medical reports that discuss the subject of accidental asphyxia. However, a systematic analysis of all documented cases in Germany over the years 2000-2008 has now been conducted, aiming at identifying patterns of accidental asphyxia, deducing findings, defining avoidance measures and recommending ways of increasing product safety and taking possible precautions. The analysis is based on a detailed retrospective analysis of all 91 relevant autopsy reports from 24 different German forensic institutes. A variety of demographic and morphological data was systematically collected and analysed. In 84 of the 91 cases, the sex of the victim was reported, resulting in a total of 57 boys (68 %) and 27 girls (32 %). The age spread ranged between 1 day and 14 years, with an average of 5.9 years. Most accidents occurred in the first year of life (20 %) or between the ages of 1 and 2 years (13 %). In 46 % of cases, the cause of death was strangulation, with the majority occurring in the home environment. In 31 % of all cases, the cause of death was positional asphyxia, the majority resulting from chest compression. In 23 % of cases, the cause of death was aspiration, mainly of foreign bodies. Today, accidental asphyxiation is a rare cause of death in children in Germany. Nevertheless, the majority of cases could have been avoided. Future incidence can be reduced by implementing two major precautions: increasing product safety and educating parents of potentially fatal risks. Specific recommendations relate to children's beds, toys and food.

[Relation of external biometric parameters to health risk and mortality--analysis and evaluation of different measurement methods and study results]. / Das Verhältnis ausserer Körpermasse zum Erkrankungsrisiko und zur Todesursache--Analyse und Bewertung unterschiedlicher Messmethoden und Studienergebnisse (I).

In clinical practice diagnoses can be found which are partially based on body measurements. By measuring body height and body weight the patient is categorised, for example by Body-Mass Index (BMI), in different adipose grades. Different diseases are associated with specific biometric parameters. Abdominal adiposity measured by waist circumference correlates with the risk of colon carcinoma and is one diagnostic criteria of the metabolic syndrome. An unhealthy waist-hip ratio (WHR) can cause a higher risk of a cardiovascular disease and dementia. By combining body measurement with cause of death found during the medicolegal autopsy, clinical relevant correlations can be uncovered. Research in medical databases (e.g. PubMed) was carried out to find studies showing possible associations between body measurements, their indices and morbidity or causes of death. This article is a selective survey of these published studies, current guidelines and the German Institute for Standardisation - Norm (DIN-Norm). We give a wide thematic overview and select relevant parameters, which should be taken during medico-legal autopsies in future. The ascertainment of those parameters and their adjustment with the findings of the medico-legal autopsies can be a key to finding predictors of history of disease and relevant morbidity risks in the institutes of forensic medicine. Such findings are very important in the assessment of risk for living patients and necessary preventive actions. Beside the measurement of waist and hip circumference mentioned in specific clinical guidelines in Germany, we suggest, after analysing the parameters, to measure the thickness of the subcutaneous fat on the anterior chest and the thigh circumference as well.

Biomarkers of exposure and potential harm in adult smokers of 3-7 mg tar yield (Federal Trade Commission) cigarettes and in adult non-smokers.

The paper reports levels of 24-h urine nicotine and five of its major metabolites (expressed as nicotine-equivalents) and blood carboxyhaemoglobin as biomarkers of exposure to particulate- and gas-phase cigarette smoke, respectively, from an exploratory pilot study of adult smokers of 3.0-6.9 mg tar delivery (Federal Trade Commission (FTC) method) cigarettes. On multiple occasions over 6 weeks, blood high-sensitivity C-reactive protein (hs-CRP), fibrinogen, HDL- and LDL-cholesterol, and 24-h urine 8-epi-prostaglandin F2alpha (8-epi-PGF2alpha) and 11-dehydro-thromboxane B2 (11-dehydro-TxB2) were also evaluated as biomarkers of potential harm. All the biomarkers examined, except for LDL-cholesterol, discriminated with high sensitivity and specificity between adult smokers and non-smokers overall. Except for HDL-cholesterol, all biomarker medians were greater in adult smokers than in non-smokers: urine nicotine-equivalents 64.514 versus < 0.034 nmol mg-1 creatinine (p<0.001), carboxyhaemoglobin 4.0 versus 0.4% saturation (p<0.001), hs-CRP 0.27 versus 0.12 mg dl-1 (p=0.05), fibrinogen 292 versus 248 mg dl-1 (p<0.001), HDL-cholesterol 46 versus 53 mg dl-1 (p=0.003), LDL-cholesterol 119 versus 109 mg dl-1 (p=0.18), urine 8-epi-PGF2alpha 1935 versus 1034 pg mg-1 creatinine (p<0.001) and urine 11-dehydro-TxB2 973 versus 710 pg mg-1 creatinine (p<0.001). All the biomarkers of exposure and most of the biomarkers of potential harm showed no time of sampling (by visit week) effect.

On-site testing of illicit drugs: the use of the drug-testing device "Toxiquick".

Since 1998, driving under the influence of drugs such as amphetamine, MDMA, MDE, cannabis, cocaine, heroine and morphine is sanctioned due to Section 24a of the Road Traffic Regulations of Germany. Therefore, from December 2000 to June 2002 altogether 751 roadside tests with the immunochemical test device Toxiquick were conducted on 302 drivers (273 male and 29 female) on oral fluid samples obtained during control actions in Franconia. The results of the tests are compared to the results obtained through quantification of corresponding blood samples by GC/MS. In general, in 75% the roadside test produced correct results and therefore gave helpful assistance to the police officers into the right direction regarding drug abuse. Except for cannabinoids, the number of false negative results was relatively small, whereas false positive results ranged between 32.2% for opiates and 10.7% for benzoylecgonine.
