    The aim of this study was to uncover patterns of pedestrian crashes. In the first stage, 34,178 pedestrian-involved crashes occurred in Iran during a four-year period were grouped into homogeneous clusters using a clustering analysis. Next, some in-cluster and inter-cluster crash patterns were analysed. The clustering analysis yielded six pedestrian crash groups. Car/van/pickup crashes on rural roads as well as heavy vehicle crashes were found to be less frequent but more likely to be fatal compared to other crash clusters. In addition, after controlling for crash frequency in each cluster, it was found that the fatality rate of each pedestrian age group as well as the fatal crash involvement rate of each driver age group varies across the six clusters. Results of present study has some policy implications including, promoting pedestrian safety training sessions for heavy vehicle drivers, imposing limitations over elderly heavy vehicle drivers, reinforcing penalties toward under 19 drivers and motorcyclists. In addition, road safety campaigns in rural areas may be promoted to inform people about the higher fatality rate of pedestrians on rural roads. The crash patterns uncovered in this study might also be useful for prioritizing future pedestrian safety research areas.

    Data from the Auckland Coronary or Stroke (ARCOS) study for the years 1983 to 1992 were analysed to describe 28-day case fatality rates from coronary heart disease among Europeans, Maori and Pacific Islands people in Auckland, New Zealand. The case fatality rate was consistently higher in each age group and for both sexes among Maori and Pacific Islands people than in Europeans. Age-standardised case fatalities for Maori and Pacific Islands people were similar at around 65 per cent, compared with around 45 per cent among Europeans, and these differences were not explained by ethnic differences in possible underreporting of nonfatal myocardial infarction, in socioeconomic status, smoking, symptoms or past myocardial infarction. There was evidence of a more rapid progression of acute coronary events to a fatal outcome among Maori and Pacific Islands people, partly explained by delays in access to life support and coronary care: greater proportions of Pacific Islands people than Maori or Europeans who died did so within an hour of onset of symptoms (56 per cent of Pacific Islands people, 47 per cent of Maori, 45 per cent of Europeans). Pacific Islands and Maori people with acute coronary events took longer to reach a coronary care unit (mean times: Pacific Islands people 8.6 hours, Maori 7.4 hours, Europeans 6.7 hours, P < 0.05), although the median times were not significantly different; life-support units were used by a majority of Pacific Islands people and Europeans (57 per cent and 55 per cent, respectively), compared with only 46 per cent of Maori, but hospital care was similar for the three groups. Further qualitative and quantitative research is needed to investigate the reasons for these ethnic disparities in case fatality rates.

    Case-fatality rates in Ebola treatment centers (ETCs) varied widely during the Ebola virus disease (EVD) outbreak in West Africa. We assessed the influence of referral pathway on ETC case-fatality rates with a retrospective cohort of 126 patients treated at the Mathaska ETC in Port Loko, Sierra Leone. The patients consisted of persons who had confirmed EVD when transferred to the ETC or who had been diagnosed onsite. The case-fatality rate for transferred patients was 46% versus 67% for patients diagnosed onsite (p = 0.02). The difference was mediated by Ebola viral load at diagnosis, suggesting a survival selection bias. Comparisons of case-fatality rates across ETCs and clinical management strategies should account for potential survival selection bias. PMID:28322693

    Data on maternal morbidity make it possible to assess how many women are likely to need essential obstetric care, and permit the organization, monitoring and evaluation of safe motherhood programmes. In the present paper we propose operational definitions of severe maternal morbidity and report the frequency of such morbidity as revealed in a population-based survey of a cohort of 20,326 pregnant women in six West African countries. The methodology and questionnaires were the same in all areas. Each pregnant woman had four contacts with the obstetric survey team: at inclusion, between 32 and 36 weeks of amenorrhoea, during delivery and 60 days postpartum. Direct obstetric causes of severe morbidity were observed in 1215 women (6.17 cases per 100 live births). This ratio varied significantly between areas, from 3.01% in Bamako to 9.05% in Saint-Louis. The main direct causes of severe maternal morbidity were: haemorrhage (3.05 per 100 live births); obstructed labour (2.05 per 100), 23 cases of which involved uterine rupture (0.12 per 100); hypertensive disorders of pregnancy (0.64 per 100), 38 cases of which involved eclampsia (0.19 per 100); and sepsis (0.09 per 100). Other direct obstetric causes accounted for 12.2% of cases. Case fatality rates were very high for sepsis (33.3%), uterine rupture (30.4%) and eclampsia (18.4%); those for haemorrhage varied from 1.9% for antepartum or peripartum haemorrhage to 3.7% for abruptio placentae. Thus at least 3-9% of pregnant women required essential obstetric care. The high case fatality rates of several complications reflected a poor quality of obstetric care. PMID:10859853

    Objectives. We assessed the 5-year, nationwide impact on road deaths of the raise in the speed limit (November 1, 1993) on 3 major interurban highways in Israel from 90 to 100 kph. Methods. We compared before–after trends in deaths as well as case fatality—an outcome independent of exposure (defined as vehicle-kilometers traveled). Results. After the raise, speeds rose by 4.5%–9.1%. Over 5 years, there was a sustained increase in deaths (15%) and case fatality rates (38%) on all interurban roads. Corresponding increases in deaths (13%) and case fatality (24%) on urban roads indicated “speed spillover.” Conclusions. Immediate increases in case fatality predicted and tracked the sustained increase in deaths from increased speeds of impact. Newtonian fourth power models predicted the effects of “small” increases in speed on large rises in case fatality rates. Countermeasures and congestion reduced the impact on deaths and case-fatality rates by more than half. PMID:15054007

    The 2008 cholera outbreak in Benin was characterized by a low case fatality rate (0.39 p.100) in the Littoral department, where 502 cases were recorded between July and December. The aim of this study was to identify the key factors associated with the low case fatality rate within the department. The cross-sectional, descriptive and analytical study conducted as part of this research used 404 patient records, focus group discussions with ten former patients, in-depth interviews with 8 health authorities involved in the response and structured face-to-face interviews with 12 health personnel involved in the treatment of patients. The data were analyzed using qualitative and quantitative content analysis based on EPIINFO 3.3.2 and EXCEL 2007 software. The results from several sources were cross-checked through triangulation. The mean age of patients was 23.72 ± 14.8 years. 39.35% patients were admitted with severe dehydration. Oral rehydration, intravenous rehydration and antibiotic therapy were given to 99.5%, 85% and 97.77% of patients, respectively. Only one hospital death was noted. The low case fatality rate was mainly due to the following factors: the high quality of care provided in a center with qualified personnel and available and free of charge treatment kits, protocols based on massive rehydration and appropriate hygiene measures, and patient compliance with the treatment plan. The response was also characterized by good coordination, wide mass and local health promotion, and selective antibiotic prophylaxis, which contributed significantly to reducing the spread of the infection.

    Objective Chromosome 22q11.2 deletion is the most commonly occurring known microdeletion syndrome. Deaths related to the syndrome have been reported, but the magnitude of death has not been quantified. This study evaluated the deletion's impact on survival and its clinical manifestations in a large cohort of Chilean patients. Design Demographic and clinical data of individuals with 22q11 deletions diagnosed between 1998 and 2013 were collected from medical records and death certificates. Case fatality rate was calculated and compared with national vital statistics. OR with 95% CI analysis was used to assess the association between clinical manifestations and death. Setting Genetic services in tertiary care centres in Chile, following patients with 22q11.2 deletion. Outcomes Fatality rate and associated factors. Results 59 of 419 patients (14.1%) died during the study period at a median of 3.4 months (range 0 to 32 years of age). Factors associated with death included congenital heart disease (OR 5.27; 95% CI 2.06 to 13.99; p<0.0001), hypocalcaemia (OR 4.27; 95% CI 1.67 to 11.15; p<0.002) and airway malacia (OR 13.37; 95% CI 1.19 to 110.51; p<0.002). Patients with deletions and defects such as tetralogy of Fallot with or without pulmonary atraesia, truncus arteriosus or ventricular septal defect, had a 2.6-fold to 4.6-fold higher death rate compared with nationwide reports for the same types of defects. Conclusions In this cohort, we observed a death rate of 14.1%, implying that one in seven patients with 22q11 deletion died during the study period. Significant associations with cardiac defects, hypocalcaemia and airway malacia were observed. Furthermore, the death risk in patients with 22q11 deletion and cardiac defects exceeded the global figures observed in Chile for infants with structurally similar but apparently isolated anomalies. These observations indicate a need to identify patients who may require specific perioperative management to improve survival

    Peripartum cardiomyopathy is a life-threatening cardiac condition affecting pregnant women either late in pregnancy or early in the post-partum period. The latest studies show a dramatic improvement in the mortality rates of women affected with this disorder, which has been correlated with advances in medical therapy for heart failure. However, patients continue to die of this condition. The following case report describes a typical patient with peripartum cardiomyopathy diagnosed on clinical grounds, along with echocardiogram findings of severe systolic dysfunction and global hypokinesis consistent with dilated cardiomyopathy. Emergency cesarean delivery had to be performed for fetal distress. There was significant improvement of the patient's condition with standard pharmacological management for heart failure at the time of discharge. However, five weeks after discharge, fatal cardiac arrest occurred. It is hoped that this article will raise awareness about this rare but potentially fatal condition and promote understanding of its main clinical features, diagnostic criteria, and conventional pharmacological management.

    In 2006, increased mortality due to leptospirosis in Reunion Island had alerted the authorities and justified the conduct of this study in order to update knowledge on the epidemiology of leptospirosis, whereas the latest epidemiological data published on the disease dated back to 2003. This study followed the scheme of a descriptive retrospective survey based on data from reporting and investigation of hospitalized cases of leptospirosis that occurred in Reunion between the 1st January 2004 and 31st December 2008. Data from the National Reference Center (NRC) have also been used. The annual number of reported cases (40 to 50) was stable over the period, which contrasted with the historical decreasing trend of incidence reported by the NRC. The circumstances of exposure were those usually associated with the disease on the island: about 80% of cases were infected between January and June, during the wet season; the main exposure factor identified was the practice of agriculture, declared or not; Leptospira icterohaemorrhagiae remained the most frequently isolated serovar, although regressing. Finally, our study has shown that excess mortality observed in 2006 did not result from an increased incidence but from a rise in the case fatality rate. This could be linked to the outbreak of chikungunya, which peaked in February 2006. In endemic areas of leptospirosis, health professionals should remain aware of the risk of occurrence of fatal cases during arbovirosis outbreaks.

  10. Estimation of MERS-Coronavirus Reproductive Number and Case Fatality Rate for the Spring 2014 Saudi Arabia Outbreak: Insights from Publicly Available Data

    2014-01-01

    Background: The Middle East Respiratory Syndrome Coronavirus (MERS-CoV) was initially recognized as a source of severe respiratory illness and renal failure in 2012. Prior to 2014, MERS-CoV was mostly associated with sporadic cases of human illness, of presumed zoonotic origin, though chains of person-to-person transmission in the healthcare setting were reported. In spring 2014, large healthcare-associated outbreaks of MERS-CoV infection occurred in Jeddah and Riyadh, Kingdom of Saudi Arabia. To date the epidemiological information published by public health investigators in affected jurisdictions has been relatively limited. However, it is important that the global public health community have access to information on the basic epidemiological features of the outbreak to date, including the basic reproduction number (R0) and best estimates of case-fatality rates (CFR). We sought to address these gaps using a publicly available line listing of MERS-CoV cases. Methods: R0 was estimated using the incidence decay with exponential adjustment (“IDEA”) method, while period-specific case fatality rates that incorporated non-attributed death data were estimated using Monte Carlo simulation. Results: 707 cases were available for evaluation. 52% of cases were identified as primary, with the rest being secondary. IDEA model fits suggested a higher R0 in Jeddah (3.5-6.7) than in Riyadh (2.0-2.8); control parameters suggested more rapid reduction in transmission in the former city than the latter. The model accurately projected final size and end date of the Riyadh outbreak based on information available prior to the outbreak peak; for Jeddah, these projections were possible once the outbreak peaked. Overall case-fatality was 40%; depending on the timing of 171 deaths unlinked to case data, outbreak CFR could be higher, lower, or equivalent to pre-outbreak CFR. Conclusions: Notwithstanding imperfect data, inferences about MERS-CoV epidemiology important for public health

    Objective: To identify sociodemographic differences in the incidence of the subtypes of first ever stroke in a multiethnic population. Methods: A prospective community stroke register (1995–8) was developed using multiple notification sources and pathological and clinical classifications of stroke. Standardisation of rates was to European and World populations and adjusted for age, sex and socioeconomic status in multivariate analyses. A multiethnic population of 234 533 in south London, of whom 21% are black was studied. Results: A total of 1254 cases were registered. The average age of stroke was 71.7 years with black patients being 11.3 years younger than white patients (p<0.0001). The incidence rate/1000 population was 1.33 (crude) (95% CI 1.26 to 1.41), 1.28 (European adjusted) (95% CI 1.2 to 1.35) with a 2.18 (95% CI 1.86 to 2.56) (p<0.0001) age and sex adjusted incidence rate ratio in the black population. Radiological diagnosis was confirmatory in 1107 (88.3%) with 862 (68.7%) infarction, 168 (13.4%) primary intracerebral haemorrhage, and 77 (6.2%) subarachnoid haemorrhage. Of the cerebral infarction cases 189 (21.9%) were total anterior circulatory, 250 (29%) partial anterior, 141 (16.4%) posterior (POCI) and 282 (32.7%) lacunar infarcts. The black group had a significantly higher incidence of all subtypes of stroke except for POCI and unclassified strokes. The incidence rate ratio (IRR) for men compared with women was 1.34 (95% confidence interval (95% CI) 1.19 to 1.50; p<0.001). The IRR for manual versus non-manual occupations in those aged 35–64 years was 1.64 (95%CI 1.22 to 2.23; p<0.0001). There was a borderline significant increase in adjusted survival at 6 months in the black group 95% (CI 0.61 to 1.03, p=0.078) with a hazard ratio of 0.79 after adjustment and stratification. Conclusions: Although the black population is at increased risk of stroke and most subtypes of stroke, this is not translated into significant differences in survival

    Snakebite envenomation affects thousands of people annually in Nepal. Published hospital-based studies of snakebite treatment in Nepal are scarce. Here we present the results of the first prospective, cross-sectional study of hospitalized envenomed snakebite cases in southcentral Nepal, a region characterized by poor pre-hospital care of snakebites, limited supply and excessive use of antivenom, and a high case/fatality ratio. We seek to identify clinical management problems and suggest potential interventions to improve treatment of snakebites. Out of the 342 patients presented with snakebites to an urban emergency department in the Terai region of Nepal between April and September of 2007, 39 patients were enrolled based on development of ptosis or swelling of bitten body parts. We collected patient demographic information and documented circumstances of snakebite, prehospital care, hospital care, and development of complications. Among 39 envenomated patients admitted to Bharatpur Hospital enrolled in the study 34 (92%) exhibited features of clinically significant neurotoxicity and were treated with antivenom. Antivenom use ranged from 4 to 98 vials of Polyspecific Indian Antivenom per patient. Each of victims (n=34) received antivenom an average of 4.3 (median) ±0.73 (standard error of mean) hours after receiving the snakebite. The overall case fatality rate was 21%. Neurotoxicity developed up to 25.8hr after suspected elapid snakebites. This was not observed for viperid snake bites. No enrolled patients received any of the currently recommended first aid for snake bite. The prevalence of nocturnal elapid snake bites, the practice of inappropriate first aid measures and highly variable administration of antivenom were identified as major challenges to appropriate care in this study. To address these issues we suggest development of a comprehensive checklist for identification of snake species, management of envenomation, and an educational program which

    This study systematically reviews the literature on the occurrence, incidence and case fatality rate (CFR) of invasive nontyphoidal Salmonella (iNTS) disease in Africa from 1966 to 2014. Data on the burden of iNTS disease in Africa are sparse and generally have not been aggregated, making it difficult to describe the epidemiology that is needed to inform the development and implementation of effective prevention and control policies. This study involved a comprehensive search of PubMed and Embase databases. It documents the geographical spread of iNTS disease over time in Africa, and describes its reported incidence, risk factors and CFR. We found that Nontyphoidal Salmonella (NTS) have been reported as a cause of bacteraemia in 33 out of 54 African countries, spanning the five geographical regions of Africa, and especially in sub-Saharan Africa since 1966. Our review indicates that NTS have been responsible for up to 39% of community acquired blood stream infections in sub-Saharan Africa with an average CFR of 19%. Salmonella Typhimurium and Enteritidis are the major serovars implicated and together have been responsible for 91%% of the cases of iNTS disease, (where serotype was determined), reported in Africa. The study confirms that iNTS disease is more prevalent amongst Human Immunodeficiency Virus (HIV)-infected individuals, infants, and young children with malaria, anaemia and malnutrition. In conclusion, iNTS disease is a substantial cause of community-acquired bacteraemia in Africa. Given the high morbidity and mortality of iNTS disease in Africa, it is important to develop effective prevention and control strategies including vaccination. PMID:28056035

    Four cases of fatal intoxications with caffeine are described. Caffeine is widely available in beverages and in different OTC-products, in many of them in combinations with other drugs like ephedrine. Caffeine is not as harmless as one might believe. An overdose of caffeine alone, intentional or not, might be deadly. It seems to be warranted to include caffeine in the drug-screening of forensic autopsy cases. It is not motivated from a medical point of view to sell pure caffeine over the counter.

    Mucormycosis due to Lichtheimia ramosa is an infrequent opportunistic infection that can potentially be angioinvasive when affecting inmunocompromised hosts. We present a fatal case of mucormycosis, affecting a 56-year-old male with diabetes mellitus and siderosis, initially admitted to our hospital due to an H1N1 infection. The subject's clinical condition worsened and he finally died because of a necrotizing bilateral pneumonia with disseminated mycotic thromboses due to Lichtheimia ramosa, which is an emerging Mucoralean fungus. This is an infrequent case because of the extent to which it affected a subject without overt immunocompromise. This case underlines the importance of an early premortem diagnosis and treatment in order to prevent rapid progression of this disease, as well as the need of considering mucormycosis when facing subjects with multiple emboli and fever unresponsive to usual antimicrobials.

    We report an unusual case of fatal airbag injury. A woman in her forties was driving a light car when it was involved in an accident. When the car was found, the left front wheel had dropped into the gutter, the front bumper was dented and the airbag had deployed. Forensic autopsy revealed that the right subclavian artery and the left vertebral artery were ruptured and 1,570 ml and 360 ml of blood with clots were observed in the left and the right thoracic cavity, respectively. It was considered that the unusual collision produced by deployment of the airbag had caused these ruptures and massive hemorrhaging. Although an airbag is an effective tool for ensuring the safety of a driver and the passengers, it may injure and occasionally kill the occupants if they do not remain in the appropriate and restrained seating position.

    The use of scopolamine as an incapacitating drug, in sexual crimes and robberies, has been known for many decades. However, blood concentrations and doses of scopolamine in those cases are largely unknown. Here we present the toxicological results of one fatal and two non-fatal cases in a series of scopolamine-facilitated robberies. In the fatal case, the concentration of scopolamine in heart blood was 0.30mg/L, about 3000 times higher than the average therapeutic level of 0.0001mg/L (for one dermal patch). In femoral blood, the concentration of scopolamine was much lower (0.0048mg/L), but still 50 times higher than therapeutic levels. The scopolamine concentration in the stomach was very high (20mg/kg) as compared to the heart blood and femoral blood, which explains the very high concentration in heart blood by postmortem leakage from the stomach. In the non-fatal case, the scopolamine concentration in serum, obtained 23h after the incident, was 0.00035mg/L. The estimated concentration of scopolamine at the time of the incident is 0.0035mg/L. In the other non-fatal case, scopolamine was detected in urine and in hair.

    Imidacloprid [1-(6-chloro-3pyridylmethyl)-N-nitroimidazolidin-2-ylideneamine] is a new and potent nitromethylene insecticide with high insecticidal activity at very low application rates. It is the first highly effective insecticide that, like nicotine, acts on the nervous system, causing blockage of postsynaptic nicotinergic acetylcholine receptors. Two fatal cases with this insecticide in two male individuals, of 33 and 66 years old, are presented. An LC/MS with electrospray method for measuring imidacloprid and its metabolites in post-mortem samples is described. In the chromatographic separation, a reverse-phase column XTerra MS C18 (2.1mm i.d.x 150 mm, 5 microm) was used and the mobile phase composed with acetonitrile and 0.1% formic acid (15:85), at a 0.25 mL/min flow rate. Samples were prepared with a liquid-liquid extraction procedure with dichloromethane. Calibration curves for imidacloprid in blood and urine samples were linear from 0.2 to 15 microg/mL. The mean recovery was 86% with a coefficient of variation of +/-5.9%. The detection limit was 0.002 microg/mL. Quantitative results were obtained for all post-mortem matrices available of the two fatal cases: blood, urine, stomach contents, lung, liver and kidney. The imidacloprid blood concentrations found in two-cases were 12.5 and 2.05 microg/mL. The authors validated a method to detect and quantify imidacloprid in post-mortem samples, and to our knowledge for the first time a post-mortem tissue distribution was performed on various samples for this insecticide.

    Smallpox (infection with Orthopoxvirus variola) remains a feared illness more than 25 years after its eradication. Historically, case-fatality rates (CFRs) varied between outbreaks (<1 to approximately 40 %), the reasons for which are incompletely understood. The extracellular enveloped virus (EEV) form of orthopoxvirus progeny is hypothesized to disseminate infection. Investigations with the closely related Orthopoxvirus vaccinia have associated increased comet formation (EEV production) with increased mouse mortality (pathogenicity). Other vaccinia virus genetic manipulations which affect EEV production inconsistently support this association. However, antisera against vaccinia virus envelope protect mice from lethal challenge, further supporting a critical role for EEV in pathogenicity. Here, we show that the increased comet formation phenotypes of a diverse collection of variola viruses associate with strain phylogeny and geographical origin, but not with increased outbreak-related CFRs; within clades, there may be an association of plaque size with CFR. The mechanisms for variola virus pathogenicity probably involves multiple host and pathogen factors.

    The age and sex specific incidence rates for cerebral infarction, primary intracerebral haemorrhage and subarachnoid haemorrhage in a population of approximately 105,000 are presented. Over four years 675 patients with a first-ever stroke were registered with the Oxfordshire Community Stroke Project. The pathological diagnosis was confirmed by computerised tomography (CT) scan, necropsy or lumbar puncture (cases of subarachnoid haemorrhage only) in 78% of cases and a further 17% were diagnosed according to the Guy's Hospital Stroke Diagnostic Score. The proportion of all first-ever strokes by pathological type was: cerebral infarction 81% (95% confidence interval 78-84), primary intracerebral haemorrhage 10% (8-12), subarachnoid haemorrhage 5% (3-7) and uncertain type 5% (3-7). These proportions are similar to other community-based studies. The overall 30 day case fatality rate was 19% (16-22), that for cerebral infarction being 10% (7-13), primary intracerebral haemorrhage 50% (38-62) and subarachnoid haemorrhage 46% (29-63). One year post stroke 23% (19-27) with cerebral infarction were dead and 65% (60-70) of survivors were functionally independent. The figures for primary intracerebral haemorrhage were 62% (43-81) dead and 68% (50-86) of survivors functionally independent and for subarachnoid haemorrhage were 48% (24-72) dead and 76% (56-96) of survivors functionally independent. There are important differences between these rates and those from other sources possibly due to more complete case ascertainment in our study. Nevertheless, the generally more optimistic early prognosis in our study, particularly for cases of cerebral infarction, has important implications for the planning of clinical trials and for the expected impact that any treatment might have on the general population.

    2005-01-01

    Objective: To describe the relation between motor vehicle type and the risk of fatally injuring a pedestrian. Design: The risk of killing a pedestrian was measured as the number of pedestrian fatalities per billion miles of vehicle travel by each vehicle type in the US in 2002 as reported by the National Highway Traffic Safety Administration's Fatality Analysis Reporting System. Interventions: None. Main outcome measures: Rates for each vehicle type by sex, age, and rural/urban roadway type and rate comparisons using relative risks (RR) and 95% confidence intervals (CIs). Results: Passenger cars and light trucks (vans, pickups, and sport utility vehicles) accounted for 46.1% and 39.1%, respectively, of the 4875 deaths, with the remainder split among motorcycles, buses, and heavy trucks. Compared with cars, the RR of killing a pedestrian per vehicle mile was 7.97 (95% CI 6.33 to 10.04) for buses; 1.93 (95% CI 1.30 to 2.86) for motorcycles; 1.45 (95% CI 1.37 to 1.55) for light trucks, and 0.96 (95% CI 0.79 to 1.18) for heavy trucks. Compared with cars, buses were 11.85 times (95% CI 6.07 to 23.12) and motorcycles were 3.77 times (95% CI 1.40 to 10.20) more likely per mile to kill children 0–14 years old. Buses were 16.70 times (95% CI 7.30 to 38.19) more likely to kill adults age 85 or older than were cars. The risk of killing a pedestrian per vehicle mile traveled in an urban area was 1.57 times (95% CI 1.47 to 1.67) the risk in a rural area. Conclusions: Outcomes reflect the ways in which a vehicle's characteristics (mass, front end design, and visibility) and its degree of interaction with pedestrians affect its risk per mile. Modifications in vehicle design might reduce pedestrian injury. The greatest impact on overall US pedestrian mortality will result from reducing the risk from the light truck category. PMID:16081753

    Halicephalobus gingivalis (previously Micronema deletrix) is a free-living nematode known to cause opportunistic infections, mainly in horses. Human infections are very rare, but all cases described to date involved fatal meningoencephalitis. Here we report the first case of H. gingivalis infection in an Australian human patient, confirmed by nematode morphology and sequencing of ribosomal DNA. The implications of this case are discussed, particularly, the need to evaluate real-time PCR as a diagnostic tool. PMID:25694532

    Chronic lymphedema and lymphangitis are common adverse effects following treatment for gynecological cancer. Because the early symptoms of necrotizing fasciitis are similar to those of lymphangitis, fatal outcome can occur if patients or physicians underestimate this condition. Here, we present a case of necrotizing fasciitis in a patient with chronic lymphedema.

    2013-01-01

    Glycogenosis type II (Pompe disease) is a rare autosomal recessive genetic disorder caused by mutations in the gene encoding the lysosomal enzyme acid α-glucosidase. The classic form is characterized by severe cardiac involvement, generalized hypotonia and exitus early in life. Presenting symptoms and signs of the disease may be neglected or underestimated, thus delaying the diagnosis. Respiratory manifestations mainly occur because of respiratory muscle weakness. However, additional mechanisms can favor the development of pulmonary complications that result in fatal respiratory failure. We herein describe a case of an infant with glycogenosis type II presenting with hepatomegaly and hypertransaminasemia, who rapidly developed fatal lung disease. PMID:23391190

    Fatal blast injuries are generally reported in literature as a consequence of the detonation of explosives in war settings. The pattern of lesion depends on the position of the victim in relation to the explosion, on whether the blast tracks through air or water, and whether it happens in the open air or within an enclosed space and the distance from the explosion. Tire explosion-related injuries are rarely reported in literature. This study presents a fatal case of blast overpressure due to the accidental explosion of a truck tire occurring in a tire repair shop. A multidisciplinary approach to the fatality involving forensic pathologists and engineers revealed that the accidental explosion, which caused a series of primary and tertiary blast wave injuries, was due to tire deterioration.

    Introduction Ranitidine hydrochloride (Zantac®), a histamine-2-receptor antagonist, is a widely used medication with an excellent safety record. Anaphylactic reaction to ranitidine is an extremely rare event and a related death has never been described in the literature. Case presentation We present the clinical history, histological and toxicological data of a 51-year-old man with negative anamnesis for allergic events, who died suddenly after the intravenous administration of one phial of Zantac® 50 mg prescribed as a routine post-surgical prophylaxis for stress ulcer. Conclusion Although the incidence of anaphylactic reactions related to ranitidine is low, caution needs to be exercised on administration of this drug. In addition, further study is needed to define strategies for the prevention of adverse drug reactions in hospitalized patients. PMID:18637187

    1993-03-01

    As asphyxial episodes during autoerotic activity are rarely reported in women, a review of eight fatal cases and one near-fatal case was conducted to delineate more clearly the characteristics of this syndrome in women. Six cases involved characteristic fatal autoerotic asphyxial activity. The remaining two fatal cases were atypical in that the apparatus that was used for sexual purposes was not intended to cause asphyxia in one case and did not directly cause asphyxial death in the second case. The final case was not fatal. Significantly, the majority of women did not use unusual clothing, props, or devices to augment their activity, for example, five were completely naked and only one was found with elaborate clothing and extra ligatures. Six of the fatal cases had objective evidence of sexual activity, three had used neck padding to prevent chafing, and eight had failed self-rescue mechanisms. Of note, the initial impression in four cases (44%) was homicide (two), attempted suicide (one), and accidental death during sexual activity with a partner (one). These results support the assertion that the manifestations of female autoerotic asphyxial activity reported to date may be initially misleading to investigators. Our purpose in presenting these findings, therefore, is to increase awareness of the more subtle features of this syndrome in women in an attempt to reduce the potential for underdiagnosis or confusion with nonaccidental death in future cases.

    The growth in popularity of flying ultralight aircraft and paragliding has been associated with an increased involvement of Emergency Medical Services because of various types of trauma suffered from both inexperienced and skilled individuals. This case presentation reports on a paraglider pilot, who was seen spinning "unusually" rapidly toward the ground, without visible attempts to regain control of the aircraft. Besides the bilateral mydriasis and the absence of any ECG activity, there was a significant swelling of face, lips, neck, and tongue. Upon opening the mouth, a dead bee was found over the tongue, underneath the palate. A fatal anaphylactic shock was the likely cause of death of the pilot while still "in mid-air." This case is certainly different from the commonly reported accidents during paragliding. An updated review of the medical literature shows no reported cases of fatal anaphylactic shock during the practice of paragliding.

    This paper describes two fatalities, three non-fatal intentional and three accidental oral ingestions of yew (Taxus baccata) leaves. In all cases the post-mortem external examinations showed no signs of violence. Internal examinations revealed small green, needle-like particles on the tongue, in the esophagus and in the stomach. Yew leaves were also identified in the stomach contents, whereas Taxus leaves were cut into small pieces and then ingested in one case. The analytical method used was based on a liquid-liquid-extraction under alkaline conditions followed by LC-MS/MS analysis (QTRAP 5500). Chromatographic separation was achieved by HPLC on a Kinetex C18 2.6u (100×3) mm. The analytical method allows the simultaneous identification and quantification of the commercially available yew alkaloids taxoids (m/z): paclitaxel (854.2→105.0/286.1), 10-deacetyltaxol (10-DAT: 812.2→105.0/286.1), baccatin III (BAC III: 604.0→105.0/327.0), 10-deacetylbaccatin III (10-DAB III: 562.1→105.0/327.0), cephalomannine [taxol B] (562.1→105.0/327.0) and of 3,5-dimethoxyphenol (3,5-DMP: 155.0→111.9/122.9) also encompassing the qualitative analysis of the alkaloidal diterpenoids (Q1→194.0/107.0); reference mass spectra obtained from a yew leaves extract: monoacetyltaxine (MAT: 568.4), taxine B (584.2), monohydroxydiacetyltaxine (MHDAT: 626.4), triacetyltaxine (TAT: 652.4), monohydroxytriacetyltaxine (MHTAT: 668.4). In both fatalities, paclitaxel, 10-DAT and cephalomannine were not identified in urine, cardiac and femoral blood but all taxoids and 3,5-DMP were present in stomach content and excreted into the bile. In urine, highest 3,5-DMP concentration was 7500 μg/L and 23,000 μg/L after enzymatic hydrolysis, respectively. In intentional and accidental poisonings, when electrocardiogram (ECG) examinations revealed ventricular tachycardia and/or prolonged QRS intervals, taxines were identified in plasma/serum, even after the ingestion of a few number of yew leaves

    Human adenoviruses (HAdVs) are highly contagious pathogens causing acute respiratory disease (ARD), such as community-acquired pneumonia. HAdV-7d, a re-emergent genomic variant, has been recently reported in Asia and the United States after a several-decade absence. However, whether HAdV-7d is associated with higher severity than other types is currently unclear. In this study, the clinical and epidemiological investigation showed that fever, cough, and sore throat were the three most common respiratory symptoms of HAdV infections. HAdV-7 caused longer duration of fever, higher morbidity of tachypnea/dyspnea, pleural effusion, diarrhea, hepatosplenomegaly, consciousness alteration, as well as higher rates of pneumonia, mechanical ventilation and higher fatality rate (28.6%) than other types, particularly HAdV-3 and HAdV-2. The genomes of seven HAdV-7d isolates from mild, severe, and fatal cases were sequenced and highly similar with each other. Surprisingly, two isolates (2011, 2012) had 100% identical genomes with an earlier strain from a fatal ARD outbreak in China (2009), which elucidates the virus origin and confirms the unexpected HAdV genomic conservation and stability. Phylogenetic analysis indicated that L1 52/55-kDa DNA packaging protein may be associated with the higher severity of illness and fatality rate of HAdV-7. Clinicians need to be aware of HAdVs in children with ARD. PMID:27848998

In this report, we describe a case of a rare extensively mixed cutaneous infection caused by Lichtheimia ramosa, Aspergillus fumigatus and Aspergillus terreus in a neutropenic patient suffering from an acute leukemia. The fatal outcome of this patient can be attributed to its hematologic malignancy, the extensive nature of the lesions and the resistance of the strains to antifungals.

    Fusarium species are ubiquitously present in environment and are well known as human pathogens with high mortality rate in immunocompromised patients. We report here two cases where immunocompromised patients developed fatal bloodstream infections by this organism. Isolates were further identified by ITS1 region sequencing which confirmed them as Fusarium solani. Antifungal susceptibility testing was done following CLSI M38-A2 guidelines to amphotericin B, fluconazole, itraconazole, voriconazole, posaconazole, caspofungin, and micafungin. Both patients had a fatal outcome and expired of septic shock. Therefore, identification up to species level is of utmost importance as that helps in directing the management of the patient thereby leading to a favourable outcome.

    Introduction Dyskeratosis congenita is a rare genodermatosis, characterized by a triad of reticular skin pigmentation, nail dystrophy and leukoplakia of mucous membranes. It is also associated with a variety of non-cutaneous abnormalities such as bone marrow failure, malignancy and pulmonary complications. Among its wide range of clinical manifestations, fatal pneumothorax has rarely been reported. Case presentation We report the case of a 31-year-old Lebanese woman with dyskeratosis congenita who succumbed to devastating bilateral pneumothoraces. Conclusion Careful surveillance of patients with dyskeratosis congenita is required as incipient respiratory failure due to pneumothorax may be successfully treated if detected at an early stage.

    Tapentadol (Nucynta) is a centrally acting opioid analgesic prescribed for the treatment of moderate to severe acute pain. Its efficacy is believed to be due to μ-opioid receptor agonist activity and inhibition of norepinephrine reuptake resulting in increased norepinephrine concentrations. There is only one other case in the literature relating to the toxicity of this agent or report of a fatality. This case report documents a case in which tapentadol was identified as the cause of death. The tapentadol concentration found in the heart blood submitted in this case was more than 20 times the upper limit of the therapeutic range. Possible mechanisms of death include respiratory depression, central nervous system depression, and serotonin syndrome. Based on the scene investigation and autopsy findings in this case, the medical examiner determined that the cause of death was narcotic (Nucynta) intoxication and the manner of death was undetermined.

    The aim of our study was to estimate the case fatality of a severe exacerbation from long-term survival data presented in the literature. A literature search identified studies reporting ≥1.5 yr survival after a severe chronic obstructive pulmonary disease (COPD) exacerbation resulting in hospitalisation. The survival curve of each study was divided into a critical and a stable period. Mortality during the stable period was then estimated by extrapolating the survival curve during the stable period back to the time of exacerbation onset. Case fatality was defined as the excess mortality that results from an exacerbation and was calculated as 1 minus the (backwardly) extrapolated survival during the stable period at the time of exacerbation onset. The 95% confidence intervals (CI) of the estimated case fatalities were obtained by bootstrapping. A random effect model was used to combine all estimates into a weighted average with 95% CI. The meta-analysis based on six studies that fulfilled the inclusion criteria resulted in a weighted average case-fatality rate of 15.6% (95% CI 10.9-20.3), ranging from 11.4% to 19.0% for the individual studies. A severe COPD exacerbation requiring hospitalisation not only results in higher mortality risks during hospitalisation, but also in the time-period after discharge and contributes substantially to total COPD mortality.

    Accidental aconitine poisoning is extremely rare in North America. This report describes the confirmation of a case of accidental aconitine poisoning using a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. The case involved a 25-year-old man who died suddenly following a recreational outing with friends where he consumed a number of wild berries and plants including one that was later identified as Monkshood (Aconitum napellus). Postmortem blood and urine samples were available for analysis. All routine urine and blood toxicology screens were negative. The LC-MS/MS method allowed sensitive quantification of aconitine, the main toxin in A. napellus, and showed 3.6 and 149 microg/L in blood and urine, respectively. These concentrations were similar to that reported in other aconitine-related deaths. This case illustrates the dangers of consuming unidentified plants, and documents concentrations of aconitine in blood and urine in a fatal case of A. napallus-related poisoning.

    OBJECTIVES: An updated version of a national surveillance system of traumatic occupational fatalities was used to explore adjusted and unadjusted trends in rates of fatal injury. METHODS: Data from the national traumatic occupational fatalities surveillance system were combined with data on employment from the United States Bureau of Labor Statistics. Poisson regression was then used to examine trends in rates of occupational fatality injuries while controlling for demographic and workplace characteristics. RESULTS: Adjusted annual changes in rates of fatal injuries ranged from a decline of 6.2% for workers in technical and administrative support occupations--for example, health, science, and engineering technicians, pilots, computer programmers--to an increase of 1.6% in machine operators, assemblers, and inspectors. For industries, annual changes ranged from a decline of 5.3% for workers in public administration--for example, justice, public order, and safety workers--to an increase of 2.6% for workers in the wholesale trade. By comparison, the annual decline over all industries and occupations was 3.1%. In many industries and occupations, an effect modification of annual trends by the age of the worker was also found with the oldest workers experiencing either no decline or a significant increase in rates of fatal injuries. CONCLUSIONS: This general pattern of decline, adjusted for the effects of demographic characteristics of the worker population, is encouraging; however, increases in rates of fatal injuries found in particular industries and occupations, suggest appropriate targets for increased injury prevention efforts.   PMID:9816383

    Rift valley fever (RVF) is a viral zoonosis that can also infect humans. Haemorrhagic RVF is a severe potentially fatal form of the disease. Although haemorrhagic RVF accounts for only 1% of all infections, death occurs in up to 5% of cases. The purpose of this report is describe a severe case of haemorrhagic RVF observed in a 22-year-old cattle breeder admitted to the intensive care units of the Joseph Raseta Befelatanana University Hospitals in Antananarivo. The disease presented as an infectious syndrome but hemorrhagic manifestations developed early (day 2). They consisted of diffuse haemorrhage events (haemorrhagic vomit, gingival haemorrhage, skin haemorrhage, urinary haemorrhage, and haemorrhage on the venous puncture site). In spite of intensive care, haemorrhagic complications lead to death on day 4 of clinical evolution. Laboratory findings demonstrated alteration in liver function and coagulation disturbances. Multiple organ failure was also observed.

    Necrotizing fasciitis is known to be a highly lethal infection of deep-seated subcutaneous tissue and superficial fascia. Reports of necrotizing fasciitis due to Streptococcus pneumoniae are exceedingly rare. We report a case of necrotizing fasciitis in a 62-yr-old man with liver cirrhosis and diabetes mellitus. He presented with painful swelling of left leg and right hand. On the day of admission, compartment syndrome was aggravated and the patient underwent surgical exploration. Intra-operative findings revealed necrotizing fasciitis and cultures of two blood samples and wound aspirates showed S. pneumoniae. The patient died despite debridement and proper antimicrobial treatment. To the best of our knowledge, this is the first case of fatal necrotizing fasciitis with meningitis reported in Korea. We also review and discuss the literature on pneumococcal necrotizing fasciitis.

    The pathology of posterior reversible encephalopathy syndrome (PRES) is undefined, since it is rarely fatal and is biopsied in only exceptional circumstances. We describe rapidly progressive PRES following stem cell transplant for acute lymphoblastic leukemia. After development of altered mental status, this 8-year-old girl had T2 prolongation of the white matter in a posterior-dominant distribution, eventually developing cerebellar edema, hemorrhage, hydrocephalus, and herniation. Despite surgical and medical management, she died 36 hours later. At autopsy, the occipital and cerebellar white matter and focal occipital cortical gray matter showed a spectrum of microvascular changes, including dilated perivascular spaces containing proteinaceous exudates and macrophages, as well as fibrinoid necrosis and acute hemorrhage, in a distribution corresponding to the neuroimaging abnormalities and reminiscent of those seen in patients with acute hypertensive encephalopathy. Of note, similar microvascular changes were not seen in the kidney or other systemic sites. Thus, the findings indicate a brain-specific microvascular compromise as the substrate of PRES, at least in the rare instance of cases progressing to fatal outcome.

Bone marrow histopathology report showed an increased in megakaryocytes count. Routine investigations reports were normal. Echocardiography and computerized tomography (CT) revealed a single mobile large intra cardiac mass originating from the right atrium and causing dynamic obstruction of the right ventricular inflow and outflow tract. Associated fatal thrombocytopenia did not respond to intravenous steroids or platelet transfusion. Patient could not be operated because of very low platelet count, and died during hospital stay before excision biopsy could be done. Pathological autopsy was not done. This is a rare case, as the fatal thrombocytopenia observed here was the result of mechanical effects like frictional and shear force, which can be attributed to the physical presence of a large intra cardiac mass resulting in obstruction to flow.

    Objectives. We examined whether neighborhood social characteristics (income distribution and family fragmentation) and physical characteristics (clean sidewalks and dilapidated housing) were associated with the risk of fatalities caused by analgesic overdose. Methods. In a case-control study, we compared 447 unintentional analgesic opioid overdose fatalities (cases) with 3436 unintentional nonoverdose fatalities and 2530 heroin overdose fatalities (controls) occurring in 59 New York City neighborhoods between 2000 and 2006. Results. Analgesic overdose fatalities were less likely than nonoverdose unintentional fatalities to have occurred in higher-income neighborhoods (odds ratio [OR] = 0.82; 95% confidence interval [CI] = 0.70, 0.96) and more likely to have occurred in fragmented neighborhoods (OR = 1.35; 95% CI = 1.05, 1.72). They were more likely than heroin overdose fatalities to have occurred in higher-income (OR = 1.31; 95% CI = 1.12, 1.54) and less fragmented (OR = 0.71; 95% CI = 0.55, 0.92) neighborhoods. Conclusions. Analgesic overdose fatalities exhibit spatial patterns that are distinct from those of heroin and nonoverdose unintentional fatalities. Whereas analgesic fatalities typically occur in lower-income, more fragmented neighborhoods than nonoverdose fatalities, they tend to occur in higher-income, less unequal, and less fragmented neighborhoods than heroin fatalities.

    Purpose Pembrolizumab, a monoclonal antibody which inhibits the programmed cell death 1 receptor, has been shown to efficaciously enhance pre-existing immune responses to malignancies. However, safety concerns must also be considered as pembrolizumab use has been associated with several life-threatening immune-related adverse events (irAEs). We report a fatal case of pembrolizumab-induced myasthenia gravis in a patient with no prior myasthenia gravis history. Case report A 63-year-old male presented with right eyelid drooping, puffiness, blurred vision, and shortness of breath two weeks after an initial infusion of pembrolizumab. He was subsequently diagnosed with new onset acetylcholine-receptor positive myasthenia gravis. Despite aggressive treatment with corticosteroids, pyridostigmine, intravenous immunoglobulin, and plasmapheresis, the patient clinically deteriorated and ultimately expired from acute respiratory failure after a 12-day hospitalization. Discussion Current package labeling for pembrolizumab warns against various irAEs associated with its use including pneumonitis, colitis, and endocrinopathies. To date, only one case of new onset myasthenia gravis and two case reports of myasthenia gravis exacerbation have been identified. This case further highlights the mortality risk associated with development of irAEs. Conclusion While rare, evidence for the development of MG associated with pembrolizumab is growing. Prompt recognition of symptoms and discontinuation of pembrolizumab is necessary to help improve prognosis.

    Enterobius vermicularis is one of the most common intestinal parasites found in humans. They commonly infest the terminal ileum and large intestine, and are usually considered an innocuous parasite that can be easily eradicated with proper treatment. However, extraintestinal migration of worms, although very rare, may lead to severe health disorders or even death. This article, reports the first fatal case of ectopic enterobiasis known to the authors, which developed in an adult patient with E. vermicularis infection, causing perforation of the large intestine and generalized bacterial peritonitis. Despite emergency laparotomy, the patient died from septic shock on the day after surgery. During pathological examination, worms were found not only in the large intestine, but also in the renal parenchyma; worm eggs were found deposited in the lungs as well.

    A man in his twenties was diagnosed with schizophrenia in his late teens. The night before his death, his family reported he drank a large amount of water, vomited, collapsed, and snored loudly while sleeping, but they did not view the event seriously as he did it routinely. The following morning, he was found dead. Autopsy revealed hyponatremia by water intoxication as the cause of death. Water intoxication has various causes. In this case, 610 ng/mL olanzapine was detected in serum samples. Although this concentration is not as high as the fatal concentrations reported in past studies, it might have caused some adverse effects. Furthermore, the observation that excessive drinking behavior started after the dose of olanzapine was increased suggests a possibility that olanzapine aggravated water intoxication.

    Toxicology testing of fatally injured workers is not routinely conducted. We completed a case-series study of 2005-2009 occupational fatalities captured by Iowa's Fatality Assessment and Control Evaluation (FACE) Program. The goals of our research were to: (1) measure the proportion of FACE cases that undergo toxicology testing, and describe the factors associated with being tested, and (2) measure the rate of positive toxicology tests, the substances identified and the demographics and occupations of victims who tested positive. Case documents and toxicology laboratory reports were reviewed. There were 427 occupational deaths from 2005 to 2009. Only 69% underwent toxicology testing. Younger workers had greater odds of being tested. Among occupational groups, workers in farming, fishing and forestry had half the odds of being tested compared to other occupational groups. Of the 280 cases with toxicology tests completed, 22% (n = 61) were found to have positive toxicology testing. Commonly identified drug classes included cannabinoids and alcohols. Based on the small number of positive tests, older victims (65+ years) tested positive more frequently than younger workers. Management, business, science, arts, service and sales/office workers had proportionately more positive toxicology tests (almost 30%) compared with other workers (18-22%). These results identify an area in need of further research efforts and a potential target for injury prevention strategies.

    Birth under water has become a widely disseminated technique that is promoted to improve the quality of labor. The case of a 42-week gestation male infant is reported who died of respiratory and multiorgan failure secondary to florid pneumonia and sepsis due Pseudomonas aeruginosa following a water birth. Other infants who have been delivered underwater have drowned or have had near-drowning episodes with significant hyponatremia and water intoxication. Local and disseminated sepsis has been reported, with respiratory distress, fevers, hypoxic brain damage, and seizures. There have also been episodes of cord rupture with hemorrhage. The postmortem investigation of such cases requires a complete autopsy of the infant, with examination of the placenta. Full details of the pregnancy and delivery and inspection of the birthing unit are also needed. A septic workup of the infant and placenta should be undertaken along with sampling of water from the birthing unit and microbiological swabbing of the equipment. Vitreous sodium levels may reveal electrolyte disturbances. While fatal cases appear rare, this may change if water births gain in popularity.

    Suicidal insulin overdoses are an under-recognized and uncommon cause of death, often relying on scene and nonspecific autopsy findings. Here, we present a case report of a fatal exogenous insulin overdose in a patient with type 1 diabetes. In our case, there were no contributory autopsy findings; however, serum analog aspart insulin levels were c. 10× the predicted therapeutic upper limit (4000, reference 6.6-55 uU/mL), which correlated with scene findings. This was specifically determined by a newly developed immunocapture liquid chromatography-tandem mass spectrometry assay, able to discriminate between various synthetic insulin analogs. Total insulin levels by immunoassay were highly elevated on the Siemens Advia Centaur, but not the Roche platforms (4741 vs. 5.2 uU/mL, respectively), showing variable sensitivity of detection within the same analog depending on assay. We discuss the prevalence and features to look for at autopsy in these types of cases. Additionally, analytical options for testing insulin levels, including new methodologies, guidance on collection of samples, as well as an outline of available historical reference range data are discussed.

    Objective To assess the association between bicycle helmet legislation and bicycle-related deaths sustained by children involved in bicycle-motor vehicle collisions. Study design We conducted a cross sectional study of all bicyclists aged 0-16 years included in the Fatality Analysis Reporting System (FARS) who died between January 1999 and December 2010. We compared fatality rates per age-specific state populations between states with helmet laws and those without helmet laws. We used a clustered Poisson multivariate regression model to adjust for factors previously associated with rates of motor vehicle fatalities: elderly driver licensure laws, legal blood alcohol limit (< 0.08% vs. ≥ 0.08%), and household income. Results A total of 1,612 bicycle-related fatalities were sustained by children <16 years old. There were no statistical differences in median household income, the proportion of states with elderly licensure laws, or the proportion of states with a blood alcohol limit of > 0.08 between states with helmet laws and those without helmet laws. The mean unadjusted rates of fatalities were lower in states with helmet laws (2.0/1,000,000 vs. 2.5/1,000,000; p= 0.03). After adjusting for potential confounding factors, states with mandatory helmet laws continued to be associated with a lower rate of fatalities (adjusted Incidence Rate Ratio 0.84; 95% CI 0.70, 0.98). Conclusions Bicycle helmet safety laws are associated with a lower incidence of fatalities among child bicyclists involved in motor vehicle collisions. PMID:23706604

    The case of a female in the latter half of her teens found dead in her father's apartment is reported. A glass containing liquid and plant remnants was found at the death scene. There were no indications of any intervention or the application of force by a third party. Autopsy showed unremarkable findings. Toxicological investigations revealed lethal doses of aconitine, a highly poisonous alkaloid and the major active compound of Aconitum napellus, in all specimens. Plant remnants were identified as A. napellus leaves by a botanist and toxicological examination of the liquid in the glass on site showed extremely high concentrations of aconitine. Additionally, laboratory results revealed that the young female was suffering from thyrotoxicosis factitia, an uncommon form of hyperthyroidism caused by misuse or overdosing of thyroid hormones in order to loose weight. A rare but serious and often fatal complication of hyperthyroidism is thyroid storm. Eventually the condition of thyroid storm due to thyrotoxicosis factitia could have contributed to the woman's death from aconitine poisoning.

    We report a fatal case of combined α-pyrrolidinovalerophenone (α-PVP) and 2-(methylamino)-1-phenylpentan-1-one (pentedrone) poisoning. A 28-year-old man was taken to hospital in asystole. Despite resuscitation efforts over 30 min, he died. The forensic autopsy showed pulmonary edema and moderately advanced atherosclerotic lesions of the arteries. Microscopic observation revealed chronic changes in the heart. Confirmation of the presence of pentedrone, α-PVP, and its metabolite 1-phenyl-2-(pyrrolidin-1-yl)pentan-1-ol (OH-α-PVP) in tissues and fluids were achieved using gas chromatography-mass spectrometry analysis after liquid-liquid extraction. A quantitative validated liquid chromatography-mass spectrometry method was used to determine the concentrations of the above designer drugs in postmortem samples. Pentedrone, α-PVP, and OH-α-PVP concentrations were 8,794, 901 and 185 ng/mL in whole blood, respectively; 100,044, 2,610 and 2,264 ng/g in the liver, respectively; 22,102, 462 and 294 ng/g in the kidney, respectively; 13,248, 120 and 91 ng/g in the brain, respectively and 500,534, 4,190 and 47 ng/g in the stomach contents, respectively. This is the first known reported death attributed to the combined use of α-PVP and pentedrone. Additionally, this article is the first to report the distribution of pentedrone in postmortem human samples.

    This paper describes a unique case of a fatal tiger attack in the wild. In the present case, a tiger fatally mauled a 34-year-old female with its claws, instead of the usual mechanism of killing by the bite injury to the neck. The autopsy revealed multiple fatal and non-fatal injuries caused by the tiger claws. The characteristic injuries due to the tooth impacts were absent as the teeth of the offending tiger were either fallen or non-functional. To the best of our knowledge, probably this rare case would be the first reported human fatality due to the tiger claw injuries in the world. The purpose of the present article is to highlight the fatal injuries due to the tiger claws, as the claw-induced fatal injuries in a tiger attack are not reported in the medico-legal literature. Moreover, this report would be an illustrative one for differentiation between the fatal injuries due to the claws and tooth impacts in a tiger attack. Furthermore, the present report establishes the importance of the tiger claws as a source of fatal injuries in a tiger attack.

    2014-01-01

    Background A recent systematic review of epidemiological studies reported intracerebral hemorrhage (ICH) incidence and mortality as unchanged over time; however, comparisons between studies conducted in different health services obscure assessment of trends. We explored trends in ICH rates in a large, representative population in New South Wales, Australia's most populous state (≈7.3 million). Methods and Results Adult hospitalizations with a principal ICH diagnosis from 2001 to 2009 were linked to death registrations through to June 30, 2010. Trends for overall, fatal, and nonfatal ICH rates within 30 days and fatal rates for 30‐day survivors at 365 days were calculated. There were 11 332 ICH patient admissions meeting eligibility criteria, yielding a crude hospitalization rate of 25.2 per 100 000 (age‐standardized rate: 17.2). Age‐ and sex‐adjusted overall rates significantly declined by an average of 1.6% per year (P=0.03). Fatal ICH declined by an average of 2.6% per year (P=0.004). For 30‐day survivors, a nonsignificant decline of 2.3% per year in fatal ICH at 365 days was estimated (P=0.17). Male sex and birth in the Oceania region and Asia were associated with an increased ICH risk, although this depended on age. Approximately 12% of ICH admissions would be prevented if the socioeconomic circumstances of the population equated with those of the least disadvantaged. Conclusions Overall and fatal ICH rates have fallen in this large Australian population. Improvements in cardiovascular prevention and acute care may explain declining rates. There was no evidence of an increase in devastated survivors because the longer term mortality of 30‐day survivors has not increased over time. PMID:25488294

    Mixed antihypertensive drug intoxication poses a significant risk for patient mortality. In tandem to antihypertensives, hypolipidemic medicines (especially statins) are often prescribed. Among their well-known adverse effects belongs rhabdomyolysis. We report a case of fatal multi-drug overdose in a 65-year-old female alcoholic. The patient was unconscious at admission. Empty blister packs indicated the abuse of 250 tablets of urapidil, 42 tablets of verapamil/trandolapril, 50 tablets of moxonidin, 80 tablets of atorvastatin and 80 tablets of diacerein. Standard measures (gastric lavage, activated charcoal, mechanical ventilation, massive doses of vasopressors, volume expansion, diuretics and alkalinization) failed to provide sufficient drug elimination and hemodynamic support and the sufferer deceased on the fourth day. Dramatic elevations of serum myoglobin (34,020 μg/L) and creatine kinase (219 μkat/L) were accompanied by rise in cardiac troponin I and creatinine. Gas chromatography revealed ethanol 1.17 g/kg (blood) and 2.81 g/kg (urine). Thin layer chromatography and gas chromatography of gastric content and urine verified verapamil, moxonidin and urapidil fragment (diacerein method was unavailable). Atorvastatin and trandolapril concentrations (LC-MS(n)) equaled 277.7 μg/L and 57.5 μg/L, resp. (serum) and 8.15 μg/L and 602.3 μg/L, resp. (urine). Histology confirmed precipitates of myoglobin with acute necrosis of proximal renal tubules in association with striated muscle rhabdomyolysis and myocardial dystrophy. Cardiogenic-distributive shock in conjunction with acute renal failure due to the combined self-poisoning with vasoactive agents and atorvastatin were determined to be this decedent's immediate cause of death. The manner of death was assigned to be suicidal.

    Rocky Mountain spotted fever is a disease caused by Rickettsia rickettsii, a bacteria transmitted by infected ticks. It is characterized by fever, exanthema, arthralgias and myalgias; but sometimes its clinical presentation is non specific. Due to its similarities with other exanthematic diseases like dengue or chikungunya, Rocky Mountain spotted fever is not a first line diagnosis, even though countries like Mexico show the ecologic and socioeconomic characteristics that favor its transmission, with a 30% mortality rate among pediatric patients. This mortality rate has been associated to a delayed diagnosis and therapy, due to a poor knowledge among physicians regarding this disease; this favors the occurrence of atypical and fulminant cases. The objective of this work is to describe a fulminant case of Rocky Mountain spotted fever, expecting that this disease could be later considered among the differential diagnosis which could directly impact its mortality rate.

    Acute respiratory infections (ARI) are a leading cause of childhood morbidity and mortality in Pakistan. The National ARI Control Programme was launched in 1989 in order to reduce the mortality attributed to pneumonia, and rationalize the use of drugs in the management of patients with ARI. WHO's standard ARI case management guidelines were adopted to achieve these objectives. The medical staff at the Children's Hospital, Islamabad, were trained in such management in early 1990; further training sessions were conducted when new staff arrived. Data on outpatients were obtained from special ARI abstract registers, which have been maintained in the outpatient department since January 1990. Details on inpatients who were admitted with ARI were obtained from hospital registers. During the period 1989-92, the use of antibiotics in the outpatient department decreased from 54.6% to 22.9% (P < 0.0001). The case fatality rate (CFR) in children admitted with ARI fell from 9.9% to 4.9% (P < 0.0001), while the overall case fatality rate fell from 8.7% to 6.2%. Our results from a tertiary health care facility show that standard ARI case management reduced both antibiotic use and expenditure on drugs. Although the ARI case management criteria, which are more sensitive than the conventional diagnostic criteria of auscultation and radiography, led to more admissions, we believe that this strategy contributed to a significant reduction in the ARI case fatality rate.

    In this study, analysis is undertaken showing disaster fatalities trends from around the world using the CATDAT Natural Disaster and Socioeconomic Indicator databases from 1900-2015. Earthquakes have caused over 2.3 million fatalities since 1900; however absolute numbers of deaths caused by them have remained rather constant over time. However, floods have caused somewhere between 1.7 and 5.4 million fatalities, mostly in the earlier half of the 20th century (depending on the 1931 China floods). Storm and storm surges (ca. 1.3 million fatalities), on the other hand, have shown an opposite trend with increasing fatalities over the century (or a lack of records in the early 1900s). Earthquakes due to their sporadic nature, do not inspire investment pre-disaster. When looking at the investment in flood control vs. earthquakes, there is a marked difference in the total investment, which has resulted in a much larger reduction in fatalities. However, a key consideration for decision-makers in different countries around the world when choosing to implement disaster sensitive design is the risk of a natural disaster death, compared to other types of deaths in their country. The creation of empirical annualised ratios of earthquake, flood and storm fatalities from the year 1900 onwards vs. other methods of fatalities (cancer, diseases, accidents etc.) for each country using the CATDAT damaging natural disasters database is undertaken. On an annualised level, very few countries show earthquakes and other disaster types to be one of the highest probability methods for death. However, in particular years with large events, annual rates can easily exceed the total death count for a particular country. An example of this is Haiti, with the equivalent earthquake death rate in 2010 exceeding the total all-cause death rate in the country. Globally, fatality rates due to disasters are generally at least 1 order of magnitude lower than other causes such as heart disease. However, in

    Liver cysts are commonly found incidentally from imaging scans or at autopsy. These benign neoplasms vary in size and represent a heterogeneous group of disorders, for which the demographics, risk factors, apparent inciting event, clinical presentation, and outcome are varied. Complications that can develop from a liver cyst include development of spontaneous hemorrhage, infection, and/or obstruction. Although the etiology of liver cysts varies, fatal rupture of a hemorrhagic liver cyst due to anabolic steroid use is a rare occurrence. In fact, there are few reported cases in journal literature. We report a case of a fatal liver cyst rupture with resultant hemoperitoneum in the presence of anabolic steroid (stanozolol) use.

    The epidemiology of measles has been investigated in Niakhar, a rural area of Senegal, during two periods, 1983-1986 and 1987-1990. Following a major increase in immunization coverage beginning in 1987, the case fatality ratio for all ages declined fourfold from the first to the second period (relative risk (RR) = 0.24, 95% confidence interval (CI) 0.13-0.46). The measles incidence for children under 10 years of age declined by 69% (95% CI 65-72) and the risk of dying of measles by 91% (95% CI 82-95). Vaccinated children who contracted measles had significantly lower case fatality ratio than unvaccinated children with measles (p = 0.038). Children infected by an immunized case tended to have lower case fatality ratio than those infected by an unimmunized index case (p = 0.104) and immunized index cases generated fewer secondary cases than unimmunized index cases (p < 0.001). Respiratory complications were more common in secondary cases infected by an index case with respiratory complications than by an index case without such complications (RR = 1.60, 95% CI 1.08-2.37), which suggests that severe cases give rise to further severe cases. As expected, there was a significant increase in the proportion of vaccinated cases in the second period (RR = 1.41, 95% CI 1.00-1.98). Mean age at infection increased from 4 to 7 years between the two periods and the change in age structure accounted for 20% of the decline in case fatality ratio. Measles immunization may contribute to lower mortality directly through reduced incidence and indirectly through increases in age at infection, less severe infection for immunized cases and changes in transmission patterns leading to reduced severity of measles.

    Mining injury surveillance data are used as the basis for assessing the severity of injuries among operator and contractor employees in the underground and surface mining of various minerals. Injury rates during 1983-2002 derived from Mine Safety and Health Administration (MSHA) database are analyzed using the negative binomial regression model. The logarithmic mean injury rate is expressed as a linear function of seven indicator variables representing Non-Coal Contractor, Metal Operator, Non Metal Operator, Stone Operator, Sand and Gravel Operator, Coal Contractor, and Work Location, and a continuous variable, RelYear, representing the relative year starting, with 1983 as the base year. Based on the model, the mean injury rate declined at a 1.69% annual rate, and the mean injury rate for work on the Surface is 52.53% lower compared to the title for work in the underground. With reference to the Coal Operator mean injury rate: the Non-Coal Contractor rate is 30.34% lower, the Metal Operator rate is 27.18% lower, the Non-Metal Operator rate is 37.51% lower, the Stone Operator rate is 23.44% lower, the Sand and Gravel Operator rate is 16.45% lower, and the Coal Contractor rate is 1.41% lower. Fatality rates during the same 20 year period are analyzed similarly using Poisson regression model. Based on this model, the mean fatality rate declined at a 3.17% annual rate, and the rate for work on the surface is 64.3% lower compared to the rate for work in the underground. With reference to the Coal Operator mean fatality rate: the Non-Coal Coil tractor rate is 234.81% higher, the Metal Operator rate is 5.79% lower, the Non-Metal Operator rate is 47.36% lower, the Stone Operator rate is 8.29% higher, the Sand and Gravel Operator rate is 60.32% higher, and the Coal Contractor rate is 129.54% higher.

    Between January 1993 and July 1996, a total of 2827 intentional cases of poisoning were registered in the University Hospitals of Leuven, Belgium. Ten of these cases were fatal. This study was set up to evaluate the substances involved, the circumstances, the features and the characteristics of the patients who died due to intentional poisoning. The male to female ratio of these fatal cases was 9 : 1. The median age was 43 years. Two groups of substances were revealed to be associated with fatal outcome. The first group consisted of chemicals (seven lethal cases): cholinesterase inhibitors ( =3), methanol ( =2) and paraquat ( =2). The second group consisted of benzodiazepines (three lethal cases). In the cases of poisoning with chemicals, death was directly related to product toxicity and the severity of the poisoning, whilst with benzodiazepines, which are considered to be relatively safe drugs even when taken in overdose, there was a clear relationship between a fatal outcome and a delay between ingestion and medical support. Product toxicity, complications and a delay in medical support may be considered as predictors for the effectiveness and efficacy of treatment and may influence which medical treatments need to be administered.

    Objective To determine whether suboptimal management in hospital could contribute to poor outcome in children admitted with meningococcal disease. Design Case-control study of childhood deaths from meningococcal disease, comparing hospital care in fatal and non-fatal cases. Setting National statistics and hospital records. Subjects All children under 17 years who died from meningococcal disease (cases) matched by age with three survivors (controls) from the same region of the country. Main outcome measures Predefined criteria defined optimal management. A panel of paediatricians blinded to the outcome assessed case records using a standardised form and scored patients for suboptimal management. Results We identified 143 cases and 355 controls. Departures from optimal (per protocol) management occurred more frequently in the fatal cases than in the survivors. Multivariate analysis identified three factors independently associated with an increased risk of death: failure to be looked after by a paediatrician, failure of sufficient supervision of junior staff, and failure of staff to administer adequate inotropes. Failure to recognise complications of the disease was a significant risk factor for death, although not independently of absence of paediatric care (P = 0.002). The odds ratio for death was 8.7 (95% confidence interval 2.3 to 33) with two failures, increasing with multiple failures. Conclusions Suboptimal healthcare delivery significantly reduces the likelihood of survival in children with meningococcal disease. Improved training of medical and nursing staff, adherence to published protocols, and increased supervision by consultants may improve the outcome for these children and also those with other life threatening illnesses.

    In the present study, a retrospective evaluation of suicide cases in the city of Port Said from 1998 to 2004 is done. The demographic data of the cases were evaluated. There were 80 cases of suicide 54 of them (67.5%) involved males. Age distribution showed a predominance in the age range 20-30 years. Methods of suicide included rodenticides intake in 25% of cases, drowning in 18.75%, burns in 16.25%, firearm injuries in 13.75%, jumping from height in 10%, drug intake in 8.75% and hanging in 7.5%. A medico-legal autopsy had been carried out for all cases. In conclusion, we emphasize the importance of rodenticides control as well as necessity of performing a psychological autopsy.

    Introduction Bartonella spp. infection is not rare and must be considered with great care in patients with suspected infective endocarditis, particularly if regular blood cultures remain sterile. Management of these infections requires knowledge of the identification and treatment of these bacteria. Case presentation A 50-year-old Senegalese man was admitted to our Department of Cardiac Surgery with a culture-negative endocarditis. Despite valvular surgery and adequate antibiotic treatment, recurrence of the endocarditis was observed on the prosthetic mitral valve. Heart failure required circulatory support. Weaning off the circulatory support could not be attempted owing to the absence of heart recovery. Bacteriological diagnosis of Bartonella quintana endocarditis was performed by molecular methods retrospectively after the death of the patient. Conclusions This case report underlines the severity and difficulty of the diagnosis of Bartonella quintana endocarditis. The clinical picture suggested possible Bartonella quintana associated myocarditis, a feature that should be considered in new cases. PMID:19830188

    Forensic medical examiners know numerous cases of non-occupational intoxication (e.g. suicide, drug intoxication, household poisoning) but rarely encounter cases of occupational poisoning with household gases. Collection of forensic chemical facts testifying to the presence of saturated hydrocarbons in blood and other tissues is a challenging task. It hampers evaluation of their toxic effect on human brain for the purpose of forensic medical examination. A method is proposed for the analysis of biological materials allowing for the detection of natural alkanes, such as butane, along with recommendations on taking samples for chemical analysis in suspected cases of poisoning with household gases. The method is designed to be employed in combination with up-to-date analytical techniques, such as capillary gas chromatography and mass spectrometry.

    ABSTRACT Between 18 May 2009 and 3 May 2010, a total of 149 fatal cases associated with pandemic influenza A (H1N1) were reported in Greece. Detailed case-based epidemiological information was available for the large majority of fatal cases. The time distribution follows an epidemic curve with a peak in the beginning of December 2009 and a second peak one month later. This is similar to that of laboratory confirmed cases and influenza-like illness cases from our sentinel surveillance system, with two weeks delay. The most commonly reported underlying conditions were chronic cardiovascular disease and immunosuppression, while the most frequently identified risk factor was obesity. These findings should be taken into consideration, when vaccination strategies are employed. PMID:21085493

    This manuscript reports Bacillus cereus sepsis in two cases with acute myelogenous leukemia (AML) who suffered complications of fatal intracranial hemorrhage during remission induction therapy. The first case was 43-year-old male with AML (M0) receiving first consolidation chemotherapy who developed sudden diarrhea, abdominal pain and spiking fever. Two days later, he died of intracranial hemorrhage. The second case was 15-year-old male with AML (M5b) who was receiving first induction chemotherapy. He developed headache and vomiting following spiking fever and diarrhea. He died of subarachnoid hemorrhage the next day. In both cases, Bacillus cereus was isolated from blood culture. Fatal intracranial hemorrhage due to severe bleeding tendency caused rapid to death in both cases. These bleeding tendencies might have been induced by B. cereus sepsis. In addition, we should not overlook B. cereus as contamination, but rather consider it as a potential pathogen, when isolated from blood culture.

  7. Prostatic paracoccidioidomycosis with a fatal outcome: a case report

    2013-01-01

    Introduction Paracoccidioidomycosis is a systemic mycosis in Latin America that can affect various organs. Few case reports of paracoccidioidomycosis affecting the prostate are found in the literature. Case presentation We present the case of a 79-year-old Caucasian man with a six-month history of irritative symptoms of the prostate (urgency, frequency and nocturia) and difficulty initiating urination that progressed to urinary retention and the use of a urinary catheter. The anatomopathological analysis of the transurethral resection of the prostate revealed chronic granulomatous prostatitis of fungal etiology (paracoccidioidomycosis) with extensive necrosis. The patient began treatment with itraconazole at a dose of 100mg/day for six months. Radiography of the thorax revealed bilaterally diffuse nodular reticular interstitial lesions. The patient progressed to respiratory failure and was sent to the intensive care unit, but suffered a cardiopulmonary arrest and was pronounced dead. Conclusions Due to the high incidence of paracoccidioidomycosis in countries like Brazil, urologists should suspect blastomycosis in all patients with symptoms of lower urinary obstruction with chronic abacterial prostatitis. Considering that paracoccidioidomycosis has the potential to affect various organs, following diagnosis, the treatment must be initiated as soon as possible. PMID:23668825

  8. Trends of hospitalizations, fatality rate and costs for acute myocardial infarction among Spanish diabetic adults, 2001-2006

    2010-01-01

    Background Acute myocardial infarction (AMI) is one of the more frequent reasons diabetic patients are admitted to hospital, and there are reports that the long-term prognosis after an AMI is much worse in these patients than in non-diabetic patients. This study aims to compare hospital admissions and costs in Spanish diabetic and non-diabetic subjects due to AMI during the period 2001-2006. Methods We conducted a retrospective study of 6 years of national hospitalization data associated with diabetes using the Minimum Basic Data Set. National hospitalization rates were calculated for AMI among diabetic and non-diabetic adults. Fatality rates, mean hospital stay and direct medical costs related to hospitalization were analyzed. Costs were calculated using Diagnosis-Related Groups for AMI in diabetics and non-diabetics patients. Results During the study period, a total of 307,099 patients with AMI were admitted to Spanish hospitals. Diabetic patients made up 29.6% of the total. The estimated incidence due to AMI in diabetics increased from 54.7 cases per 100,000 in 2001 to 64.1 in 2006. Diabetic patients had significantly higher mortality than nondiabetic patients after adjusting for age, gender, and year (OR 1.11 [95% CI, 1.08-1.14]). The cost among diabetic patients increased by 21.3% from 2001 to 2006. Conclusions Diabetic patients have higher rates of hospital admission and fatality rates during the hospitalization after an AMI than nondiabetic patients. Diabetic adults who have suffered an AMI have a greater than expected increase in direct hospital costs over the period 2001-2006. PMID:20205960

    Indoleamine 2,3-dioxygenase (IDO), which is the rate-limiting enzyme for tryptophan (trp) catabolism, may play a critical role in various inflammatory disorders. Recent studies on trauma patients have suggested that the degradation of trp is associated with the development of sepsis. The role of IDO activity in bacteremic patients is unclear. We studied IDO activity in 132 patients with bacteremia caused by Staphylococcus aureus, Streptococcus pneumoniae, beta-hemolytic streptococcae, or Eschericia coli. The serum concentrations of trp and its metabolite kynurenine (kyn) were measured by reverse-phase high-performance liquid chromatography 1 to 4 days after the positive blood culture and on recovery. The kyn-to-trp ratio (kyn/trp), reflecting the activity of the IDO enzyme, was calculated. The maximum value in the ratio for every patient during 1 to 4 days after positive blood culture was used in analysis. The maximum kyn/trp ratio was significantly higher in nonsurvivors versus those who survived (193.7 vs. 82.4 micromol/mmol; P = 0.001). The AUC(ROC) of maximal kyn/trp in the prediction of case fatality was 0.75 (95% confidence interval, 0.64-0.87), and the kyn/trp ratio at a cutoff level of 120 micromol/mmol showed 83% sensitivity and 69% specificity for fatal disease. A kyn/trp ratio greater than 120 micromol/mmol was associated with increased risk of death versus low (case fatality in a multivariate model adjusted for potential confounders. The data in this report demonstrate that IDO activity is markedly increased in bacteremia patients, constituting an independent predictor of severe disease and case fatality.

    After bathing at a hot spring resort, a 75-year-old man presented to the emergency department because of seizure-like attack with loss of conscious. This is the first case of primary amebic meningoencephalitis (PAM) caused by Naegleria fowleri in Taiwan. PAM was diagnosed based on detection of actively motile trophozoites in cerebrospinal fluid using a wet-mount smear and the Liu's stain. The amoebae were further confirmed by PCR and gene sequencing. In spite of administering amphotericin B treatment, the patient died 25 days later.

    We used a chronobiological inferential statistical method to investigate circadian rhythms of hypophyseal hormones, cortisol, melatonin and catecholamines in two females of the same family affected by fatal familial insomnia. Case 1 (confirmed at autopsy) presented an absent or progressive loss of circadian rhythms of all hormones. In case 2 there was a loss of GH circadian rhythm and a less significant rhythm for melatonin, catecholamines and gonadotropins. These results confirm the role of the thalamus in regulating hormonal circadian rhythm.

    Background Transfusion related acute lung injury (TRALI) is a potentially fatal Acute Lung Injury following transfusion of blood components. Hypotheses implicate donor-derived anti-human leukocyte antigen or granulocyte antibodies reacting with recipients' leukocytes, releasing inflammatory mediators. Lack of agreement on underlying cellular and molecular mechanisms renders improving transfusion safety difficult and expensive. Case Presentation Literature search has not revealed any case of TRALI from Pakistan. We report the case of fatal TRALI in a 68 year old male who received blood products after coronary artery by-pass surgery. Conclusion This article aims to create awareness about this complication and suggests that post transfusion cardiopulmonary instability should alert to the possibility of TRALI. PMID:19055759

    2001-11-01

    Due to variations in the thickness of U.S. coal seams, there is great variability in the height of the roof where underground miners work. Restrictions imposed by low seam heights have important safety consequences. As the height of their workplace decreases, miners must stoop, duck walk, or crawl, and their vision, posture, and mobility become increasingly restricted. Low seam height also places important restrictions on the design of mobile equipment and other mining machinery. Using the employment and injury data reported to the Mine Safety and Health Administration (MSHA) from 1990 to 1996, small underground bituminous coal mines with less than 50 employees were stratified by average coal seam height according to the following categories: low (< or =42"), medium (43"-60"), and high (> or =61"). Injury rates for both nonfatal days lost and fatality cases were examined by seam height and leading type of injury incidents. The leading types of incidents associated with fatalities were roof falls and powered haulage equipment. In comparison to high-seam mines, miners working in low or medium seams are at higher risk of being killed by powered haulage equipment, roof bolting machines, and falls of unsupported roof. The leading types of incidents associated with nonfatal injuries were handling materials and powered haulage. As mining height decreases, miners are at increasingly higher risk of having a nonfatal injury from incidents involving roof bolting machines, load-haul-dump equipment, personnel carriers, and powered haulage conveyors. As mining height increases, miners are at increasingly higher risk of having a nonfatal injury from slips and falls and incidents involving shuttle cars and roof and rib falls. Knee injuries are a particularly severe problem in low-seam mines. The rate of injuries to miners while crawling or kneeling is 10 times higher in low seams than in high seams.

    The infectious origin of fatal cases of calf pneumonia was studied in 48 calves from 27 different herds on postmortem examination. Lung tissue samples were examined by pathological, histological, bacterial culture, virus isolation and immunohistochemical methods for the detection of viral and bacterial infections. Pneumonia was diagnosed in 47/48 cases and infectious agents were found in 40/47 (85%) of those cases. The presence of multiple respiratory pathogens in 23/40 (57.5%) cases indicated the complex origin of fatal calf pneumonia. The most important respiratory pathogens were Mannheimia-Pasteurella in 36/40 (90%) cases, followed by Arcanobacterium pyogenes in 16/40 (40%) cases, Mycoplasma bovis in 12/40 (30%) cases, and bovine respiratory syncytial virus in 4/40 (10%) cases. Histophilus somni was detected in 2/40 (5%) cases, while bovine herpesvirus-1, bovine viral diarrhoea virus and parainfluenza virus-3 were each found in 1/40 (2.5%) case. Mastadenovirus, bovine coronavirus, influenza A virus or Chlamydiaceae were not detected.

    A case of fatal radiation hepatitis occurring after treatment with 2200 rad given by the moving strip technique is presented. This fatality occurred in a 28-year-old woman with persistent ovarian carcinoma despite prolonged chemotherapy. Scans of the liver using computerized tomography, /sup 99m/Tc sulfur colloid, and /sup 99m/Tc diisopropyl iminodiacetic acid showed abnormalities only in sulfur colloid uptake and these resolved late in the course. Death was caused by progressive hepatic and renal failure. Postmortem examination showed changes typical of radiation hepatitis. Only 32 cases of radiation hepatitis have been previously reported and they are reviewed. The possible role of prolonged prior chemotherapy in enhancing sensitivity to radiotherapy is considered.

    Lyme disease is a systemic infection commonly found in the northeastern, mid-Atlantic, and north-central regions of the United States. Of the many systemic manifestations of Lyme disease, cardiac involvement is uncommon and rarely causes mortality. We describe a case of a 17-year-old adolescent who died unexpectedly after a 3-week viral-like syndrome. Postmortem examination was remarkable for diffuse pancarditis characterized by extensive infiltrates of lymphocytes and focal interstitial fibrosis. In the cardiac tissue, Borrelia burgdorferi was identified via special stains, immunohistochemistry, and polymerase chain reaction. The findings support B. burgdorferi as the causative agent for his fulminant carditis and that the patient suffered fatal Lyme carditis. Usually, Lyme carditis is associated with conduction disturbances and is a treatable condition. Nevertheless, few cases of mortality have been reported in the literature. Here, we report a rare example of fatal Lyme carditis in an unsuspected patient.

    Age-adjusted 28-day case-fatality rates were higher among Mexican Americans than among non-Hispanic whites and higher among women than among men hospitalized for definite or possible myocardial infarction in Corpus Christi, Nueces County, Texas, from May 1, 1988, through April 30, 1990. The authors therefore examined whether these higher case-fatality rates were associated with greater prevalence of previously diagnosed coronary heart disease or diabetes; with greater age, frequency of definite myocardial infarction, or congestive heart failure; with higher values of indicators of severity of infarction, including peak creatine phosphokinase levels and scales prognostic of early mortality after myocardial infarction; and with differences in receipt of in-hospital therapy. The overall 28-day case-fatality rate among 1,228 patients hospitalized for myocardial infarction during a 24-month period was 7.3%. After adjustment for age; diabetes; myocardial infarction class (definite vs. possible); congestive heart failure; the Norris and Peel severity indices; peak total creatine phosphokinase; and receipt of thrombolytic therapy, aspirin, calcium channel blockers, beta-blockers, anticoagulants, angioplasty, and bypass surgery, the risk of 28-day case-fatality for Mexican Americans in relation to non-Hispanic whites was 1.49 (95% confidence interval 0.92-2.40). The corresponding risk for women in relation to men was 1.80 (95% confidence interval 1.12-2.89). These findings should alert clinicians to the high-risk status of these groups of patients.

    Pulmonary edema is a common finding in fatal methamphetamine intoxication. However, the underlying mechanism remains poorly understood. This study investigated the molecular pathology of alveolar damage involving pulmonary edema in forensic autopsy cases. Seven candidate reference genes (RPL13A, YWHAZ, GUSB, SDHA, GAPDH, B2M, and ACTB) were evaluated in the lung by the geNorm module in qBase(plus) software. RPL13A, YWHAZ, and GUSB were identified as the most stable reference genes. Using these validated reference genes, intrapulmonary mRNA expressions of matrix metalloproteinases (MMPs), intercellular adhesion molecule-1 (ICAM-1), claudin-5 (CLDN-5), and aquaporins (AQPs) were examined. Relative mRNA quantification using TaqMan real-time PCR assay demonstrated higher expressions of all markers except for AQP-5 in fatal METH intoxication cases. These findings suggested alveolar damage and compensatory response in fatal METH intoxication cases. Systematic analysis of gene expressions using real-time qPCR is a useful tool in forensic death investigation.

    Statistically 10% of head and neek trauma is caused by animal bite, more often inflicted by dogs. More than 50% of victims are infants and small children. Generally, the result of dogbite is superficial trauma but there are cases of deep soft tissue defects with amputation and multiple bone fractures. In case described in this article, an elderly woman suffered a dog attack, wich resulted in extensive face and head injuries. In spite of receiving proper treatment, the patient passed away. It is highly probable that underlying Syncumar therapy caused complications which contributed to the fatal outcome. Because of it's unusual nature we found this case to be of interest for publication.

    Although Chikungunya infection is emerging as an important public health problem in many countries, it is not regarded as a life-threatening disease. Information dealing with fatal cases is scarce. We herein describe three patients with Chickungunya infection who presented with multiple organ failure and died within 24h of admission. Two cases had positive anti-dengue IgM, but dengue coinfection was rejected based on the clinical features and results of real-time reverse transcription polymerase chain reaction. These cases illustrate the challenges of the diagnosis and management of severe Chikungunya infection.

    In the order Hymenoptera, bees, hornets, and wasps are well-known stinging insects whose envenoming can be fatal. Their stinging attacks are common in rural and forested areas of Sri Lanka. However, fatal stinging by the large-bodied carpenter bees is unreported. We report the first known case of a fatal sting by the large carpenter bee, Xylocopa tranquebarica, in a forested area in Puttalam (North Western Province) in the dry zone of Sri Lanka. A 59-year-old healthy male manual laborer accompanied by a fellow worker had been fixing a fence on a coconut estate bordering a forested area when a flying insect emerged from a dead tree trunk and stung him on his face. His coworker, who was watching the incident, killed the insect. The victim complained of immediate intense pain in the face and collapsed on the ground just after resuming work after 10 minutes of resting. He was found dead on admission to the hospital 90 minutes later. Autopsy showed normal coronary arteries and heart, but the lungs were slightly congested and contained secretions in the bronchi. Acute anaphylaxis was the most likely cause of death. This case presents the habitat, morphology, attack pattern, and the medical importance of large carpenter bees.

    A human dog bite-related fatality generally refers to death proximately caused by trauma from a dog's teeth and jaws. According to The Humane Society of the United States, more than 300 individuals died of dog attacks in the United States between 1979 and 1996. Children <12 and elders >70 years represent the typical victims. Pit bull-type dogs, Rottweilers, and German Shepherds constitute the majority of canines implicated in these fatalities.This is a 15-year (1991-2005) retrospective review of dog bite-related fatalities undergoing medicolegal investigation in Kentucky. Of the 11 deaths, 10 consisted of multiple bite marks and blunt force injuries of the head and neck, trunk, and extremities. In 1 case, an asplenic victim's immediate cause of death was bacterial sepsis secondary to a dog bite. Individuals ranged between 14 months and 87 years; 7 (63.6%) were < or =6 years; 10 (90.9%) individuals were white, and 8 (72.7%) were male. Forensic odontological examinations were performed on the dogs in 4 cases. The requisite multidisciplinary investigation includes a detailed assessment of the scene, the victim, and dog or dogs suspected in the attack.

    We report a fatal case of gastrointestinal perforation and hemorrhage secondary to the ingestion of a foreign body. While engaged in an amateur futsal competition, an apparently healthy young man suddenly collapsed and his respiration ceased. Autopsy revealed a 3-mm circular perforation on the gastric wall fundus with a significant amount of clotted blood within the gastric lumen. On inspection, a foreign body consisting of a bristle-like hair, later identified via electron microscopy to be a cat vibrissa, i.e. a whisker, was found along the perforation margin. Thus, the inadvertent ingestion of fine, sharp objects (even a cat whisker) can lead to gastric perforation and bleeding, which might prove fatal under given circumstances.

    On August 1, 2001, Korey Stringer, a Pro Bowl offensive tackle for the Minnesota Vikings, became the first and to date the only professional American football player to die from exertional heat stroke (EHS). The death helped raise awareness of the dangers of exertional heat illnesses in athletes and prompted the development of heat safety policies at the professional, collegiate, and interscholastic levels. Despite the public awareness of this death, no published study has examined in detail the circumstances surrounding Stringer's fatal EHS. Using the well-documented details of the case, our study shows that Stringer's fatal EHS was the result of a combination of physiological limitations, organizational and treatment failings, and extreme environmental conditions. The COMfort FormulA (COMFA) energy budget model was used to assess the relative importance of several extrinsic factors on Stringer's EHS, including weather conditions, clothing insulation, and activity levels. We found that Stringer's high-intensity training in relation to the oppressive environmental conditions was the most prominent factor in producing dangerous, uncompensable heat stress conditions and that the full football uniform played a smaller role in influencing Stringer's energy budget. The extreme energy budget levels that led to the fatal EHS would have been avoided according to our modeling through a combination of reduced intensity and lower clothing insulation. Finally, a long delay in providing medical treatment made the EHS fatal. These results highlight the importance of modern heat safety guidelines that provide controls on extrinsic factors, such as the adjustment of duration and intensity of training along with protective equipment modifications based on environmental conditions and the presence of an emergency action plan focused on rapid recognition and immediate on-site aggressive cooling of EHS cases.

    Pedestrian protection evaluations have been developed to encourage vehicle front-end designs that mitigate the consequences of vehicle-to-pedestrian crashes. The European New Car Assessment Program (Euro NCAP) evaluates pedestrian head protection with impacts against vehicle hood, windshield, and A-pillars. The Global Technical Regulation No. 9 (GTR 9), being evaluated for U.S. regulation, limits head protection evaluations to impacts against vehicle hoods. The objective of this study was to compare results from pedestrian head impact testing to the real-world rates of fatal and incapacitating injuries in U.S. pedestrian crashes. Data from police reported pedestrian crashes in 14 states were used to calculate real-world fatal and in- capacitating injury rates for seven 2002-07 small cars. Rates were 2.17-4.04 per 100 pedestrians struck for fatal injuries and 10.45-15.35 for incapacitating injuries. Euro NCAP style pedestrian headform tests were conducted against windshield, A-pillar, and hoods of the study vehicles. When compared with pedestrian injury rates, the vehicles' Euro NCAP scores, ranging 5-10 points, showed strong negative correlations (-0.6) to injury rates, though none were statistically significant. Data from the headform impacts for each of the study vehicles were used to calculate that vehicle's predicted serious injury risk. The predicted risks from both the Euro NCAP and GTR 9 test zones showed high positive correlations with the pedestrian fatal and incapacitating injury rates, though few were statistically significant. Whether vehicle stiffness is evaluated on all components of vehicle front ends (Euro NCAP) or is limited to hoods (GTR 9), softer vehicle components correspond to a lower risk of fatality.

    To investigate the influence of inhaling carbon monoxide (CO)-containing gases in fires, forensic autopsy cases of fire victims (n=193) were examined in comparison with control cases involving other causes of fatal CO intoxication (n=6 :COHb, 69.5-83.0%). Fire victims with blood carboxyhemoglobin (COHb) levels over 60% (n=76) showed a larger arterio-venous difference in blood COHb level compared with other fire victims and other fatal CO intoxication. However, biochemical findings for myocardial, cerebral damage or respiratory distress were milder in most cases, independent of blood cyanide levels, being similar to those in fatality due to inhalation of blast furnace gas with an extremely high concentration of CO (ca. 40%). These observations suggest that an acutely fatal factor in fires involves inhalation of gases containing high amounts of CO, which may induce peracute circulatory collapse before causing marked myocardial and cerebral damage or respiratory distress.

    The influenza epidemic in 2015-2016 in Russia is characterized by a sharp increase of influenza cases (beginning from the second week of 2016) with increased fatalities. Influenza was confirmed in 20 fatal cases registered among children (0-10 years), in 5 cases among pregnant women, and in 173 cases among elderly people (60 years and older). Two hundred and ninety nine people died from influenza were patients with some chronic problems. The overwhelming majority among the deceased (more than 98%) were not vaccinated against influenza. We isolated 109 influenza A(H1N1)pdm09 and one A(H3N2) virus strains from 501 autopsy material samples. The antigenic features of the strains were similar to the vaccine strains. A phylogenic analysis of hemagglutinin revealed that influenza A(H1N1)pdm09 virus strains belonged to 6B genetic group that had two main dominant subgroups during the 2015-2016 season. In Russia strains of the first group predominated. We registered an increased proportion of strains with D222G mutation in receptor-binding site. A herd immunity analysis carried out immediately prior to the epidemic showed that 34.4% blood sera samples collected in different regions of Russia were positive to A/California/07/09(H1N1)pdm09. We came to a conclusion that public awareness enhancement is necessary to reduce unreasonable refusals of vaccination.

    Even though there have been previously published reports on firearm injuries in various countries, the incidence and pattern of death from firearm injuries in Thailand have not been studied before. In present study, 149 fatal firearm injuries from 2002 to 2011 were reviewed. At total of 7126 autopsies, fatal firearm injuries comprised of 2.09% (n = 149) of total autopsies cases. Among those victims, 136 were male (91.3%), 13 (8.7%) were female. The youngest age of victim was 10 years and the oldest was 79 years. Mean age of the victims was 33.79 years and median age was 30 years. Outdoor incident was the most common scene of crime. Night time incident (18:00 PM-05:59 AM) was higher than day time one. Most of the cases occurred in week ends (n = 52). Homicide (77.2%) was the most frequent manner of death. Head/face and chest were the most common sites of entrance. The autopsy report also study on entrance wound, range and types of projectiles. Blood alcohol concentration was examined in 122 cases and 38 victims showed positive results, 11 cases revealed using of illegal substances in blood and urine analysis. This study also included the association between manner of death and other factors. Age group, time of incidence, place of incidence, number of entrance wound and range showed statistically significant association with manner of death.

    During the Northern Hemisphere winter of 2003–2004 the emergence of a novel influenza antigenic variant, A/Fujian/411/2002-like(H3N2), was associated with an unusually high number of fatalities in children. Seventeen fatal cases in the UK were laboratory confirmed for Fujian/411-like viruses. To look for phylogenetic patterns and genetic markers that might be associated with increased virulence, sequencing and phylogenetic analysis of the whole genomes of 63 viruses isolated from fatal cases and non fatal “control” cases was undertaken. The analysis revealed the circulation of two main genetic groups, I and II, both of which contained viruses from fatal cases. No associated amino acid substitutions could be linked with an exclusive or higher occurrence in fatal cases. The Fujian/411-like viruses in genetic groups I and II completely displaced other A(H3N2) viruses, but they disappeared after 2004. This study shows that two A(H3N2) virus genotypes circulated exclusively during the winter of 2003–2004 in the UK and caused an unusually high number of deaths in children. Host factors related to immune state and differences in genetic background between patients may also play important roles in determining the outcome of an influenza infection. PMID:22412998

    All cases of fatal oxycodone toxicity presenting to the New South Wales Department of Forensic Medicine over the period January 1, 1999, to December 31, 2008, were retrieved. A total of 70 cases were identified. The mean age was 48.9 years, 58.6% were men, 21.4% were suicides, and in 30% oxycodone had not been prescribed to the decedent. Injecting drug users constituted 27.1% of cases, and oxycodone tablets were injected immediately prior to death by 21.4%. The mean blood oxycodone concentration was 0.40 mg/L (range 0.06-53.00 mg/L). In all cases, psychoactive substances other than oxycodone were also detected, most frequently hypnosedatives (68.6%), other opioids (54.3%), antidepressants (41.4%), and alcohol (32.9%). Preexisting systemic disease was common: cardiovascular (64.2%), pulmonary (49.3%), hepatic (66.7%), and renal (43.9%).

    This case report describes a woman who developed fatal gastric dilatation after binge eating. She called an ambulance because of stomach pain. When she arrived at the hospital, she did not look seriously ill. However, she rapidly became unconscious and collapsed immediately after she was laid on the examination table in a supine position. Postmortem chest x-ray and computed tomography showed right shift of the mediastinum and raised left diaphragm caused by massive gastric distension. Computed tomography showed no visible inferior vena cava. We think that her sudden deterioration was caused by movement of her stomach contents. Radiographic images provided some clues to the cause of her rapid collapse and death.

    A fatal case due to severe methemoglobinemia is presented. A male in his forties was found unconscious in his house and, despite intensive care, death was confirmed approximately 11 hours later. Toxicological analysis using ion chromatography revealed the presence of chlorate in the stomach contents. However, chlorate was not detected in the blood, and no other drugs or ethanol were detected in the blood either. We concluded that the cause of death was presumably due to chlorate poisoning, based on the results of the autopsy and the toxicological examination.

    OBJECTIVES: To estimate the relative risk of death from work related injury in a steelworks, associated with exposure to various occupational hazards, sociodemographic factors, and medical history. MATERIAL AND METHODS: The study was a nested case-control design. It was based on a cohort of men employed in the steel plant of USIMINAS, Brazil between January 1977 and August 1990, who were followed up to November 1992. The cases were defined as all workers in the cohort who died from injury in the study period and whose death had been notified to the Brazilian Ministry of Labour as being related to work. Four controls per case, matched to cases on year of birth, were randomly selected from among workers employed in the plant at the time of death of the matching case. Data on potential risk factors for occupational injury were extracted from company records; for the controls these data were abstracted for the period preceding the death of the matching case. RESULTS: There were 37 deaths related to work injuries during the study period. Four surviving workers were selected as controls for each case, but for eight the personnel records were incomplete, leaving 140 controls in all. Significantly increased risk of fatal injury related to work was associated with exposure to noise, heat, dust and fumes, gases and vapours, rotating shift work, being a manual worker, and working in the steel mill, coke ovens, blast furnaces, and energy and water supply areas. Risk of fatal injury related to work increased with intensity of exposure to noise (P (trend) = 0.004) and heat (P < 0.001), and increased greatly with a hazard score that combined information on noise, heat, dust, and gas exposure (P < 0.001). Number of years of schooling (P = 0.03) and salary level (P = 0.03) were both negatively associated with risk. In a multivariate analysis including all these significant factors, only hazard score and area of work remained associated with death from injury related to work. The

    Cat-scratch disease resulting from Bartonella henselae infection is usually a benign, self-limited process in immunocompetent children. Even the rare cases associated with neurologic manifestations are not generally fatal. We report a case of a previously healthy 6-year-old boy with cat-scratch disease, systemic dissemination, and encephalitis that led to his death. Autopsy revealed perivascular lymphocytic infiltrates and microglial nodules in the brain. To our knowledge, this finding has not been previously reported in B. henselae infection, possibly because of the paucity of material available for complete neuropathologic evaluation. This case illustrates the extreme severity of the spectrum with which cat-scratch disease can present and provides evidence of brain histopathology that may be representative of the disease.

    Acute solvent exposures may contribute to automobile accidents because they increase reaction time and decrease attention, in addition to impairing other behaviors. These effects resemble those of ethanol consumption, both with respect to behavioral effects and neurological mechanisms. These observations, along with the extensive data on the relationship between ethanol consumption and fatal automobile accidents, suggested a way to estimate the probability of fatal automobile accidents from solvent inhalation. The problem can be approached using the logic of the algebraic transitive postulate of equality: if A=B and B=C, then A=C. We first calculated a function describing the internal doses of solvent vapors that cause the same magnitude of behavioral impairment as ingestion of ethanol (A=B). Next, we fit a function to data from the literature describing the probability of fatal car crashes for a given internal dose of ethanol (B=C). Finally, we used these two functions to generate a third function to estimate the probability of a fatal car crash for any internal dose of organic solvent vapor (A=C). This latter function showed quantitatively (1) that the likelihood of a fatal car crash is increased by acute exposure to organic solvent vapors at concentrations less than 1.0 ppm, and (2) that this likelihood is similar in magnitude to the probability of developing leukemia from exposure to benzene. This approach could also be applied to other potentially adverse consequences of acute exposure to solvents (e.g., nonfatal car crashes, property damage, and workplace accidents), if appropriate data were available.

    We report a case of fatal water intoxication due to polydipsia. A 69-year-old schizophrenic male was found dead at his room of the hospital in which he had been admitted. Medico-legal autopsy was carried out to determine the cause of his death. The autopsy revealed no severe trauma leading him to the death. Internally, it was noticed that the stomach was vigorously expanded, including fluid contents. Intracardiac blood, being dark-red in color, seemed to be diluted. The both lungs ballooned aqueously, showing apparently edema. However, there was neither macroscopic nor histopathological lesion, being responsible for his death. Postmortem biochemical analyses revealed severe hyponatremia of 92 mEq/ml. In cases with short postmortem interval, serum sodium level almost similarly reflected antemortem level. According to his psychiatric doctor, he had been diagnosed as water intoxication due to polydipsia. Moreover, at 2 h before the discovery of his body, he had been found to drink much running water. It was concluded the cause of his death as fatal water intoxication.

    The spider bites are quite frequent and often resolve quickly without leaving outcomes; only some species are capable of causing necrotic and systematic lesions in humans. Among them, we should mention the genus Loxosceles. The venom released from the spider bite of Loxosceles species is composed of proteins, enzymes, and nonenzymatic polypeptides. The phospholipase D family was identified as the active component of the venom. This family of enzymes is responsible for the local and systemic effects observed in loxoscelism. Phospholipases D interact with cell membranes triggering alterations which involve the complement system and activation of neutrophils and they cause the dermonecrotic skin lesions and systemic effects. We describe a fatal case of acute intoxication caused by a spider bite probably belonging to the species Loxosceles. The initial lesion was localized to a finger of a hand. Clinical course was worsening with deep necrotic lesions on limb, shock, hemolysis, acute kidney failure, and disseminated intravascular coagulation. All therapies were ineffective. This is the first fatal case described in Europe. PMID:27651958

    In early 1988, an increased incidence of acute hepatitis was observed in villages along the Shebeli River in the Lower Shebeli region of Somalia. This was followed by a large epidemic that lasted until late 1989. In a survey of 142 villages with a population of 245,312 individuals, 11,413 icteric cases were recorded, of which 346 died, corresponding to an attack rate and a case fatality rate of 4.6% and 3.0%, respectively. The etiologic role of hepatitis E virus (HEV) in this epidemic was proven by demonstrating anti-HEV in 128 of 145 sampled cases as a sign of recent infection with HEV. In three villages, where a special study protocol was implemented, the attack rate was found to increase significantly with age from 5% in the group 1-4 years of age to 13% in the group 5-15 years of age and to 20% for persons older than 15 years of age. Among cases 20-39 years of age, the female-to-male ratio was 1.5:1, which was a significant predominance of females. As in other hepatitis E outbreaks, there was a high fatality rate in pregnant females, estimated to be 13.8%. The epidemic peaked with the rise in the level of the river during rainfall, suggesting that the disease was waterborne. The attack rate was higher (6.0%) in villages supplied with river water, while fewer cases were recorded in those relying on wells or ponds for their water supply, 1.7% and 1.2%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

  4. Viekira Pak Induced Fatal Lactic Acidosis: A Case Report of an Unusual Side Effect

    PubMed Central

    2016-01-01

    Viekira Pak is a new direct-acting antiviral agent that has an excellent efficacy in treating patients with chronic HCV. FDA released a safety warning that Viekira Pak can cause serious liver injury mostly in patients with underlying advanced liver disease. We report the first case of fatal lactic acidosis presenting 3 days after initiating therapy with Viekira Pak. Although it is very hard to precisely determine the cause of lactic acidosis, our case highlights an unusual side effect that ensued after starting the medication. Given the complexity of drug-drug interactions that can happen with the new direct-acting antiviral agents and the paucity of data regarding coadministration and methods of monitoring, a thorough review should be pursued prior to initiating these medications.

    Background: Opioids have narrow therapeutic windows, and errors in ordering or administration can be fatal. The purpose of this study was to describe deaths involving hydromorphone and morphine, which have similar-sounding names, but different potencies. Methods: In this case series, we describe deaths of patients admitted to hospital or residents of long-term care facilities that involved hydromorphone and morphine. We searched for deaths referred to the Patient Safety Review Committee of the Office of the Chief Coroner for Ontario between 2007 and 2012, and subsequently reviewed by 2014. We reviewed each case to identify intervention points where errors could have been prevented. Results: We identified 8 cases involving decedents aged 19 to 91 years. The cases involved errors in prescribing, order processing and transcription, dispensing, administration and monitoring. For 7 of the 8 cases, there were multiple (2 or more) possible intervention points. Six cases may have been prevented by additional patient monitoring, and 5 cases involved dispensing errors. Interpretation: Opioid toxicity deaths in patients living in institutions can be prevented at multiple points in the prescribing and dispensing processes. Interventions aimed at preventing errors in hydromorphone and morphine prescribing, administration and patient monitoring should be implemented and rigorously evaluated.

    A case of fatal viscerotropic Rocky Mountain spotted fever with virtual absence of cutaneous lesions was diagnosed at autopsy by specific immunofluorescent demonstration of Rickettsia rickettsii in spleen, kidney, epididymis and skin. The clinical presentation was that of insidious onset of fever, renal failure, hypotension, hyponatremia and obtundation over a 10 day period. The patient had respiratory insufficiency, hypocalcemia, increases in creatinine phosphokinase (CPK), serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), lactic dehydrogenase (LDH), alkaline phosphatase, billirubin and serum phosphate, grand mal seizure, myalgia and unremitting shock with death occurring on day 12 of illness. Postmortem examination revealed severe vasculitis with interstitial nephritis and multifocal tubular necrosis, pericholangitis with bile stasis, glial nodules in the brain, multifocal rhabdomyonecrosis, interstitial pneumonitis and mild interstitial myocarditis. Risk factors which this patient shared with other patients with fatal Rocky Mountain spotted fever were failure to recognize a rash, failure to obtain a tick bite history, male sex, black race and age greater than 30 years.

    We present the first reported fatality from argon gas emboli during prostate cryosurgery. The decedent underwent cryotherapy for prostate carcinoma using cryoablation probes which were cooled with argon and nitrous oxide and warmed with helium. Minutes into the procedure he experienced sudden cardiovascular collapse and could not be resuscitated. Postmortem examination was performed at the request of family and healthcare providers. Collection of tissues and blood samples had to be conducted carefully to capture suspected noble gases,argon, and helium. Specimens were submitted to Saint Louis University Forensic Toxicology Laboratory for toxicological examination and for evaluation of the composition of the gas retrieved from the vascular system.Gas chromatography mass spectrometric analyses confirmed argon in blood, brain, liver, and gas retrieved from the aorta. These samples had significant argon compared with room air also sent for comparison. The manner of death was accident. To date, there have been no intraoperative surgical fatalities reported from prostatic cryotherapy. We report such an unfortunate death to raise awareness in the medical community. We also describe how to collect and handle blood and tissue samples to submit for toxicological analysis in cases of volatile gas emboli.

    As an antihistamine, diphenhydramine (DPH) is well known for its use in allergy treatment. Since its introduction in 1946, it has been marketed under various trade names, the most popular being Benadryl. Three years after its introduction, the first fatality due to DPH toxicity was reported in 1949. To better understand the incidence of fatalities due to DPH monointoxication, we reviewed deaths that were reported from 2 data sources: (1) the English-language literature using PubMed, from 1946 through 2003; and (2) the Annual Report of the American Association of Poison Control Centers Toxic Exposure Surveillance System (ARAAPCCTESS), from 1983 through 2002. The results were then tabulated using age, gender, clinicopathologic findings, and toxicology results. Combined results from both data sets show the following mean (and range) for age and DPH levels: Adult, 35.6 years (18-84) and 19.53 mg/L (0.087-48.5); pediatric, 8.6 years (1.25-17) and 7.4 mg/L (1.3-13.7); infant, 31 weeks (6 weeks-11 months) and 1.53 mg/L (1.1-2.2), respectively. Most deaths were certified as accident or suicide; however, 6 infant homicides were reported. The most common symptoms for all cases were cardiac dysrhythmias, seizure activity, and/or sympathetic pupil responses. The most common autopsy finding was pulmonary congestion.

    Death certificates and medical examiner records have been useful yet imperfect data sources for work-related fatality research and surveillance among adult workers. It is unclear whether this holds for work-related fatalities among adolescent workers who suffer unique detection challenges in part because they are not often thought of as workers. This study investigated the utility of using these data sources for surveillance and research pertaining to adolescent work-related fatalities. Using the state of North Carolina as a case study, we analyzed data from the death certificates and medical examiner records of all work-related fatalities data among 11- to 17-year-olds between 1990-2008 (N = 31). We compared data sources on case identification, of completeness, and consistency information. Variables examined included those on the injury (e.g., means), occurrence (e.g., place), demographics, and employment (e.g., occupation). Medical examiner records (90%) were more likely than death certificates (71%) to identify adolescent work-related fatalities. Data completeness was generally high yet varied between sources. The most marked difference being that in medical examiner records, type of business/industry and occupation were complete in 72 and 67% of cases, respectively, while on the death certificates these fields were complete in 90 and 97% of cases, respectively. Taking the two sources together, each field was complete in upward of 94% of cases. Although completeness was high, data were not always of good quality and sometimes conflicted across sources. In many cases, the decedent's occupation was misclassified as "student" and their employer as "school" on the death certificate. Even though each source has its weaknesses, medical examiner records and death certificates, especially when used together, can be useful for conducting surveillance and research on adolescent work-related fatalities. However, extra care is needed by data recorders to ensure that

    Fatalities due to an extreme ambient temperature might present with poor or nonspecific pathologies; thus, the diagnosis of the cause of death in such cases is one of the most difficult tasks in forensic pathology. The present study investigated the molecular pathology of alveolar damage involving pulmonary edema with special regard to hyperthermia (heatstroke) and hypothermia (cold exposure) in forensic autopsy cases (total, n=122; within 48 h postmortem). Intrapulmonary mRNA and immunohistochemical expressions of matrix metalloproteinases (MMPs), intercellular adhesion molecule-1 (ICAM-1), claudin-5 (CLDN-5) and aquaporins (AQPs) were examined. Relative mRNA quantification using Taqman real-time PCR assay demonstrated higher expressions of all markers except for AQP-5 in fatal hyperthermia, and higher expression of MMP-9 in fatal hypothermia. Acute cardiac death, mechanical asphyxiation, fire fatality and intoxication did not present any characteristic findings. In immunostaining, only MMPs showed evident differences among the causes of death: MMP-9 was intensely positive in most cases of hyperthermia and hypothermia, but MMP-2 expression was evident only in hyperthermia. These findings suggest alveolar damage involving pulmonary edema, characteristic of fatal hyperthermia and hypothermia. Systematic analysis of gene expressions using real-time PCR might be a useful procedure in forensic death investigation.

    A fatal case of carnitine deficiency is described. The patient had intermittent metabolic acidosis, fluctuating hepatomegaly, and progressive muscle weakness since 22 months of age. One of two liver biopsies revealed lipid accumulation in the hepatocytes, and a muscle biopsy at age 5 years showed a lipid storage myopathy. Type 1 fibres were the most severely affected. Satellite and vascular endothelial cells also contained abnormal lipid deposits. Quantitative electron microscopy demonstrated an approximately 50-fold increase in lipid material, and a twofold increase in mitochondria in myofibres. The muscle carnitine level was less than one-seventh of the lowest value encountered in 74 biopsies from non-weak or neuromuscular disease controls. The basic abnormality in this patient is assumed to be a defect in carnitine biosynthesis. Images PMID:874508

    The first fatal case of Yam bean and Rotenone toxicity in Thailand was studied at Forensic Medicine, Chiang Mai, Thailand. A Chinese Taiwan man, 59 years old, was found dead after Yam bean ingestion. Yam bean toxicity and death have been found very rarely in the world and has not been reported in Thailand The Yam bean plant is grown widely in Northern Thailand. But many people know that mature pods, seeds and filage of the Yam bean, except the tuberous root, are very toxic. The victim ate a lot of Yam bean seeds and died within 2 hours with respiratory failure. The authors detected Rotenone substance in Yam bean seeds, gastric content and 72 ng/ml blood by HPLC. Also generalized microscopic hemorrhage in the brain, lungs, liver and adrenal glands which were of characteristic pathology were detected. The authors concluded that the cause of death was asphyxia from Yam bean or Rotenone toxicity.

    Streptococcus suis is a recognized pathogen that may cause important diseases in pigs and humans. This microorganism has been repeatedly isolated from wild boar (Sus scrofa). However, its health implications for this wild species are still unknown. This article reports a detailed description of a fatal case of septicemia by S. suis affecting a young wild boar. The affected animal, about 15 days old, was found near death and exhibiting neurologic signs at a wild boar estate in southwestern Spain. Postmortem examination showed generalized congestion, brain hemorrhages and lobular pneumonia. Histopathological evaluation demonstrated the presence of meningitis and encephalitis with marked congestion and suppurative bronchopneumonia. Streptococcus suis serotype 2 isolates exhibiting important virulence factors (extracellular factor, muramidase-released protein, and suylisin) were isolated from the affected animal. This study confirms the presence of potentially virulent and zoonotic strains of S. suis in wild boar from Spain.

    Four cases of fatal disseminated Scedosporium prolificans (inflatum) infection occurring in neutropenic patients are reported. Because of hospital renovation, the patients were cared for in a temporary hematologic facility. S. prolificans (inflatum) was isolated from blood cultures of these four patients, two of whom underwent full necropsy, and revealed abundant vegetative hyphae and ovoid conida with truncate bases in many organs. In vitro susceptibility testing of fungal strains showed all isolates to be resistant to amphotericin B, flucytosine, miconazole, ketoconazole, fluconazole, and itraconazole, with MICs greater than 16 micrograms/ml. The reported infections, two in each of two rooms, occurred over a period of 1 month, with very similar clinical outcomes. Circumstancial evidence suggested a nosocomial outbreak, but the environmental samples collected from the rooms, corridors, and adjacent areas did not yield S. prolificans (inflatum). Nevertheless, circumstantial evidence suggested a nosocomial outbreak of S. prolificans (inflatum) infection. PMID:8586719

    The most effective resuscitative procedure in choking by foreign bodies is the Heimlich maneuver, described for the first time by Henry Heimlich (1974) and recognized by the US Surgeon General (1985) as the "only method that should be used for the treatment of choking from foreign body airway obstruction." If performed correctly, this lifesaving maneuver is associated with rare complications, of which the most frequent are rib fractures and gastric or esophagus perforations. Other rare traumatic injuries such as pneumomediastinum, aortic valve cusp rupture, diaphragmatic herniation, jejunum perforation, hepatic rupture, or mesenteric laceration have been described.However, we are unaware of previous reports of splenic rupture after Heimlich maneuver. We present an interesting case of fatal hemoperitoneum due to a hilar laceration of the spleen following a correctly performed Heimlich maneuver.

    We report a fatal case of hypermagnesemia caused by oral ingestion of milk containing magnesium chloride as a folk remedy. The autopsy of the 75-year-old woman showed no injury or illness as the cause of death. Neither alcohol nor controlled drugs were found by the toxicological analysis. Her posthumous serum magnesium concentration was 10.2 mg/dL. The concentration of magnesium in serum was higher than that of the previous reports. Therefore, the cause of death was considered to be hypermagnesemia. Recently, the prescription drugs, over-the-counter drugs, and health foods containing magnesium are consumed as supplements in the world, and their potential toxicity should be recognized.

    Gallbladder injuries are extremely rare in blunt trauma, with a reported incidence of <2%. We report an autopsy case of fatal hemorrhagic shock due to intra-abdominal bleeding resulting from complete avulsion of the gallbladder associated with liver cirrhosis. Multiplanar images derived from multislice computed tomography (MSCT) performed as part of pre-autopsy screening showed complete avulsion of the gallbladder without any other associated intra-abdominal injuries, facilitating forensic autopsy planning. In this report, we discuss the role of MSCT in cases of fatal intra-abdominal bleeding caused by avulsion of the gallbladder and discuss the mechanism of this injury. PMID:23986858

    The authors of this paper wish to present a case of fatal cor pulmonale with right ventricular hypertrophy complicated by a congenital myopathy. It is our intention to demonstrate the importance of vigilant clinical assessment of children with a congenital myopathy, regardless of the exact etiology of their disease, or family history of disease severity. This case highlights the risk for fatal complications if hypoventilation and respiratory insufficiency go unrecognized in myopathic children. Consequently, we recommend respiratory and cardiac monitoring surveillance as well as appropriate referral to specialists in the management of such children.

    We report the case of a 44-year-old man who experienced a fatal and untreatable delayed vasospasm after resection of a recurrent temporal IV grade primitive neuroectodermal tumor (PNET). The histological analysis demonstrated a rare rhabdoid variant of the tumor with a diffuse myxoid degeneration; molecular investigations demonstrated an upregulation of IL-1β and IL-6 expression in the recurrence. We reviewed the pathophysiology of the vasospasm that occurs after tumors resection, and due to the rarity of case, we speculated on the possibility that specific histological and molecular features of the tumor could have contributed to the delayed and fatal complication.

    Background In November 1993, the Israeli government increased the speed limit for all vehicles from 90 to 100 km per hour on a total of 115 km of its three major interurban highways. Design/Setting We use ARIMA time series intervention models to evaluate the effect of the raise in speed limit on fatalities, serious injuries, and case‐fatality for years 1988–1999. Motor vehicle crash data came from the Central Bureau of Statistics of Israel. Results Between January 1988 and December 1999, a total of 6029 persons were killed and 45 616 were seriously injured on roads in Israel. For all roads combined, the time series ARIMA model indicated that there were 4.69 more deaths per month (p<0.001), or 347 more than expected in the post‐intervention period. Case‐fatality rate (CFR) on all roads combined rose significantly (p<0.001). Modified case‐fatality rate (CFRS) showed an increase of 2.5 deaths per 100 serious casualties (p<0.001). Conclusions The impact of raised speed limits was immediate and sustained. The largest increase in deaths occurred on interurban roads but a spillover effect was observed on urban roads as well. The increases in deaths and case‐fatality rates persisted six years after the speed limit change despite major countermeasures and increasing congestion throughout the period of follow‐up.

    We report clinical features and histopathological findings in fatal cases with dengue (DENV) and chikungunya (CHIKV) co-infection identified at the Colombian National Institute of Health between September 2014 and October 2015. Seven such cases were documented. Dengue serotype 2 virus was identified in six cases. All patients were adults and comorbidities were present in four. Fever, arthralgia or myalgia was present in all cases. The frequency of rash, haemorrhage, oedema, and gastrointestinal symptoms was variable. Laboratory findings such as thrombocytopenia, renal failure, and leukocyte count were also inconsistent between cases. Post-mortem tissue examination documented focal hepatocellular coagulative necrosis in three cases, incipient acute pericarditis in one and tubulointerstitial nephritis in one. This study provides evidence of mortality in patients with DENV and CHIKV co-infection. Fatal cases were characterised by variable clinical and laboratory features. Evaluation of histopathology of autopsy tissues provided evidence of the pathological consequences of the disease.

    SUMMARY An outbreak of Legionnaire's disease was detected in Pamplona, Spain, on 1 June 2006. Patients with pneumonia were tested to detect Legionella pneumophila antigen in urine (Binax Now; Binax Inc., Scarborough, ME, USA), and all 146 confirmed cases were interviewed. The outbreak was related to district 2 (22 012 inhabitants), where 45% of the cases lived and 50% had visited; 5% lived in neighbouring districts. The highest incidence was found in the resident population of district 2 (3/1000 inhabitants), section 2 (14/1000). All 31 cooling towers of district 2 were analysed. L. pneumophila antigen (Binax Now) was detected in four towers, which were closed on 2 June. Only the strain isolated in a tower situated in section 2 of district 2 matched all five clinical isolates, as assessed by mAb and two genotyping methods, AFLP and PFGE. Eight days after closing the towers, new cases ceased appearing. Early detection and rapid coordinated medical and environmental actions permitted immediate control of the outbreak and probably contributed to the null case fatality. PMID:17662166

    Monitoring fatalities at wind energy facilities after they have been constructed can provide valuable information regarding impacts of wind power development on wildlife. The objective of this monitoring is to estimate abundance of a super-population of carcasses that entered the area within a designated period of time. By definition, the population is not closed and carcasses can enter as they are killed through collision with turbines, and leave as they are removed by scavengers or decompose to a point where they are not recognizable. In addition, the population is not inherently mobile, but can only change location through some external force. A focus on number of animal carcasses comprising the super-population, combined with peculiar traits that resist classic assumptions, distinguish fatality estimation at wind-power facilities from more classic abundance estimates that can be addressed through mark-recapture techniques or other well-known abundance estimators. We review the available methods to estimate the super-population of carcasses at wind power facilities. We discuss the role of these estimates in determining appropriate levels of minimization and mitigation of impacts to individual species of concern. We discuss the potential to extrapolate these measurements to reflect the cumulative effect of the industry on individual species. Finally, we suggest avenues of research needed to strengthen our understanding of the effect wind power development has, and might have in the future, on wildlife on this continent and worldwide.

    Patient: Female, 63 Final Diagnosis: Cerebral amyloid angiopathy Symptoms: Altered mental state • aphasia • hemiplegia Medication: — Clinical Procedure: — Specialty: Neurology Objective: Unusual clinical course Background: Cerebral amyloid angiopathy (CAA) is an increasingly recognized cause of lobar intracerebral hemorrhage (ICH) and cognitive impairment in the aging population. Magnetic resonance imaging (MRI) of cerebral microbleeds is the most reliable option for clinical diagnosis of suspected CAA. The pathophysiology of microbleeds and ICH in CAA is not well understood, but it is thought to be the result of vessel weakening and rupture secondary to amyloid deposition. Little evidence has been established pertaining to the time course of recurrent CAA-related microbleeds or larger hemorrhages. Although several risk factors have been associated with an increased risk of ICH in CAA, there are no current treatment guidelines for recurrent hemorrhaging in CAA. Case Report: We present a rare case of rapidly sequential and fatal lobar hemorrhaging in the setting of suspected CAA, diagnosed by numerous microbleeds on MRI, compounded by the use of subcutaneous heparin in a 63-year-old female patient. Conclusions: This case broadens our understanding of a rarely identified progression of CAA and illustrates the need for further investigation of the use of subcutaneous heparin in the setting of probable CAA.

    The study investigated trends in traffic crashes with fatal and non-fatal injuries in Arkhangelsk, Russia in 2005-2010. Data were obtained from the road police. Negative binomial regression with time regressor was used to investigate trends in monthly incidence rates (IRs) of crashes, fatalities, and non-fatal injuries. During the six-year period, the police registered 4955 crashes with fatal and non-fatal injuries, which resulted in 217 fatalities and 5964 non-fatal injury cases. The IR of crashes with fatal and non-fatal injuries per total population showed no evident change, while the IR per increasing total number of motor vehicles decreased on average by 0.6% per month. Pedestrian crashes constituted 51.8% of studied crashes, and pedestrians constituted 54.6% of fatalities and 44.5% of non-fatal injuries. The IRs of pedestrian crashes and non-fatal pedestrian injuries per total population decreased on average by 0.3% per month, and these were the major trends in the data.

    Study objective: To investigate the effect of recall on estimation of non-fatal injury rates in Tanzania. Design: Retrospective population based survey. Setting: Eight branches in an urban area and six villages in a relatively prosperous rural area in Tanzania. Subjects: Individuals of all ages living in households selected by cluster sampling. Main outcome measures: Estimated non-fatal injury rates calculated at each of the 12 recall periods (one to 12 months before the interview). Results: Out of a population of 15 223 persons, 509 individuals reported 516 injuries during the preceding year. Of these 313 (61.5%) were males and 196 (38.5%) females. The data showed notable declining incidence rates from 72 per 1000 person-years when based on a one month recall period to 32.7 per 1000 person-years for a 12 month recall period (55% decline). The decline was found for injuries resulting in fewer than 30 days of disability whereas rates for severe injuries (disability of 30 days or more) did not show a consistent variation with recall period. Decline in injury rates by recall period was higher in rural than in urban areas. Age, sex, and education did not notably affect recall. Conclusions: Longer recall periods underestimate injury rates compared with shorter recall periods. For severe injuries, a recall period of up to 12 months does not affect the rate estimates. It is essential that a recall period of less than three months be used to calculate injury rates for less severe injuries. PMID:15691990

    2012-01-01

    Background Viral infections during pregnancy can pose serious threats to mother and fetus from the time of conception to the time of delivery. These lead to congenital defects, spontaneous abortion and even death. The definitive diagnosis and management of pregnancy-related viral infections may be challenging especially in less resourced countries. Case presentation We present clinical and laboratory responses to the diagnosis and management of three cases of fulminant hepatitis secondary to Hepatitis E viral infection in pregnancy. Case 1 was a 31-year-old Ghanaian woman who presented with a week’s history of passing dark urine as well as yellowish discoloration of the eyes. She subsequently developed fulminant hepatitis secondary to Hepatitis E viral infection, spontaneously aborted at 24 weeks of gestation and later died. Case 2 was also a 31-year-old Ghanaian woman who was admitted with a four-day history of jaundice. She had low grade fever, but no history of abdominal pain, haematuria, pale stool or pruritus. She next developed fulminant hepatitis secondary to Hepatitis E viral infection. However, she did not miscarry but died at 28 weeks of gestation. Case 3 was a 17-year-old Ghanaian woman who was referred to the tertiary health facility on account of jaundice and anaemia. She had delivered a live male infant at maturity of 32 weeks but noticed she was jaundiced and had a presentation of active disease 3 days prior to delivery. The baby was icteric at birth and on evaluation, had elevated bilirubin (mixed type) with normal liver enzymes. Hepatitis E virus infection was confirmed in both mother and baby. However, the jaundice and the hepatomegaly resolved in mother and baby after 5 and 12 days respectively. Conclusion To the best of our knowledge, these are the first documented cases of fatal fulminant hepatic failures resulting from HEV infection in Ghana. PMID:22937872

    Accidents and fatalities at USA amusement parks are rare, yet when they do occur, they can injure, maim, and even kill. This dissertation sheds light on how three family-owned amusement parks learned and improved as organizations from their own and others' failure experience. Using a multiple case study design, 18 participants were interviewed.…

  10. Severe malaria - a case of fatal Plasmodium knowlesi infection with post-mortem findings: a case report

    PubMed Central

    2010-01-01

    Background Zoonotic malaria caused by Plasmodium knowlesi is an important, but newly recognized, human pathogen. For the first time, post-mortem findings from a fatal case of knowlesi malaria are reported here. Case presentation A formerly healthy 40 year-old male became symptomatic 10 days after spending time in the jungle of North Borneo. Four days later, he presented to hospital in a state of collapse and died within two hours. He was hyponatraemic and had elevated blood urea, potassium, lactate dehydrogenase and amino transferase values; he was also thrombocytopenic and eosinophilic. Dengue haemorrhagic shock was suspected and a post-mortem examination performed. Investigations for dengue virus were negative. Blood for malaria parasites indicated hyperparasitaemia and single species P. knowlesi infection was confirmed by nested-PCR. Macroscopic pathology of the brain and endocardium showed multiple petechial haemorrhages, the liver and spleen were enlarged and lungs had features consistent with ARDS. Microscopic pathology showed sequestration of pigmented parasitized red blood cells in the vessels of the cerebrum, cerebellum, heart and kidney without evidence of chronic inflammatory reaction in the brain or any other organ examined. Brain sections were negative for intracellular adhesion molecule-1. The spleen and liver had abundant pigment containing macrophages and parasitized red blood cells. The kidney had evidence of acute tubular necrosis and endothelial cells in heart sections were prominent. Conclusions The overall picture in this case was one of systemic malaria infection that fit the WHO classification for severe malaria. Post-mortem findings in this case were unexpectedly similar to those that define fatal falciparum malaria, including cerebral pathology. There were important differences including the absence of coma despite petechial haemorrhages and parasite sequestration in the brain. These results suggest that further study of knowlesi malaria

    A 62-year-old male died of colchicine poisoning after accidental ingestion of Colchicum autumnale (meadow saffron). He ate a salad of plant with green leaves regarded as wild garlic (Allium ursinum). A few hours later he developed symptoms of gastroenteritis and was admitted to hospital. In spite of gastric lavage, activated charcoal and supportive measures, multi-organ system failure developed over the next two days. Laboratory analysis showed highly elevated blood concentrations of hepatic enzymes, creatine kinase, lactate dehydrogenase and blood urea nitrogen, as well as leukocytopenia and thrombocytopenia. Mechanical ventilation, dopamine, noradrenaline, crystalloid solutions and fresh frozen plasma were applied but despite treatment the patient died five days after the ingestion. Post-mortem examination revealed hepatic centrilobular necrosis, nephrotoxic acute tubular necrosis, petechial bleeding in fatty tissue, blunt and shortened intestinal villi and cerebral toxic edema. Botanical identification of incriminated plant gave Colchicum autumnale which confirmed colchicine poisoning. Although the accidental ingestion of Colchicum autumnale is rare and to our knowledge only five such cases have been described in detail, this is the second fatal case in Croatia described in the last 3 years.

    Datura poisonings have been previously described but remain rare in forensic practice. Here, we present a homicide case involving Datura poisoning, which occurred during a robbery. Toxicological results were obtained by second autopsy performed after one previous autopsy and full body embalmment. A 35-year-old man presented with severe stomach and digestive pain, became unconscious and ultimately died during a trip in Asia. A first autopsy conducted in Asia revealed no trauma, intoxication or pathology. The corpse was embalmed with methanol/formalin. A second autopsy was performed in France, and toxicology samples were collected. Scopolamine, atropine, and hyoscyamine were found in the vitreous humor, in addition to methanol. Police investigators questioned the local travel guide, who admitted to having added Datura to a drink to stun and rob his victim. The victim's death was attributed to disordered heart rhythm due to severe anticholinergic syndrome following fatal Datura intoxication. This is a recent case of a rare homicide involving Datura that highlights general information on Datura and discusses forensic interpretation after a previous autopsy and body embalmment.

    Four cases of fatal toxoplasmosis in three endemic New Zealand avian species are reported. Between 2009 and 2012, two kereru (Hemiphaga novaeseelandiae), one North Island brown kiwi (Apteryx mantelli), and one North Island kaka (Nestor meridionalis) were submitted for necropsy examination. On gross postmortem, the kiwi had marked hepatosplenomegaly while the kaka and two kereru had swollen, slightly firm, deep-red lungs. Histologically there was extensive hepatocellular necrosis in the liver of the kiwi while the kaka and kereru showed severe fibrinous bronchointerstitial pneumonia. In the kiwi, protozoal organisms were present within both hepatocytes and Kupffer cells of the liver and within the epithelial cells and macrophages of the interstitium of the lungs in the kaka and two kereru. The diagnosis of toxoplasmosis was confirmed with immunohistochemistry and PCR of paraffin-embedded formalin-fixed tissue of the liver, lungs, or both. Genotyping of up to seven markers revealed that an atypical Type II isolate of Toxoplasma gondii was present in at least three of the cases. This study provides evidence that T. gondii can cause mortality in these endemic species and suggests further research is needed to determine the full extent of morbidity and mortality caused by this parasite in New Zealand's unique avifauna.

    Objectives Firefighters regularly respond to hazardous situations that put them at risk for fatal occupational injuries. Traumatic occupational fatality surveillance is a foundation for understanding the problem and developing prevention strategies. We assessed four surveillance systems for their utility in characterizing firefighter fatalities and informing prevention measures. Methods We examined three population-based systems (the Bureau of Labor Statistics' Census of Fatal Occupational Injuries and systems maintained by the United States Fire Administration and the National Fire Protection Association) and one case-based system (data collected through the National Institute for Occupational Safety and Health Fire Fighter Fatality Investigation and Prevention Program). From each system, we selected traumatic fatalities among firefighters for 2003–2006. Then we compared case definitions, methods for case ascertainment, variables collected, and rate calculation methods. Results Overall magnitude of fatalities differed among systems. The population-based systems were effective in characterizing the circumstances of traumatic firefighter fatalities. The case-based surveillance system was effective in formulating detailed prevention recommendations, which could not be made based on the population-based data alone. Methods for estimating risk were disparate and limited fatality rate comparisons between firefighters and other workers. Conclusions The systems included in this study contribute toward a greater understanding of firefighter fatalities. Areas of improvement for these systems should continue to be identified as they are used to direct research and prevention efforts. PMID:21800748

    This study has been designed in order to identify factors increasing the risk of a fatal outcome when occupational accidents occur. The aim is to provide further evidence for the design and implementation of preventive measures in occupational settings. The Spanish Ministry of Labour registry of occupational injuries causing absence from work includes information on individual and occupational characteristics of injured workers and events. Registered fatal occupational injuries in 2001 (n=539) were compared to a sample of non-fatal injuries in the same year (n=3493). Risks for a fatal result of occupational injuries, adjusted by individual and occupational factors significantly associated, were obtained through logistic regression models. Compared to non-fatal injuries, fatal occupational injuries were mostly produced by trapping or by natural causes, mostly related to elevation and transport devices and power generators, and injured parts of body more frequently affected were head, multiple parts or internal organs. Adjusted analyses showed increased risk of fatality after an occupational injury for males (adjusted odds ratio aOR=10.92; 95%CI 4.80-24.84) and temporary workers (aOR=5.18; 95%CI 2.63-10.18), and the risk increased with age and with advancing hour of the work shift (p for trends <0.01). Injuries taking place out of the usual occupational setting (aOR=2.85, 95%CI 2.27-3.59), or carrying out atypical tasks (aOR=2.08; 95%CI 1.27-3.39) showed increased risks of a fatal result too, as occupational accidents in agricultural or construction companies. These data can help to select and define priorities for programmes aimed to prevent fatal consequences of occupational injuries.

    The objective of this study was to identify individual, family and caregiver risk factors for serious child maltreatment, resulting in hospitalization or death, among children and families investigated by Child Protective Services (CPS). We conducted a matched case-control study of 234 children who sustained fatal or serious nonfatal maltreatment due to physical abuse or neglect and whose mother was named in a CPS investigation between 1999 and 2013. A total of 702 children and their caregivers were included in the study with 234 cases matched 2:1,resulting in 468 controls. Data on potential risk factors were abstracted from three county administrative databases. Differences between cases and controls were calculated and multivariable conditional logistic regression was used to estimate risk models. Variables associated with increased risk for serious maltreatment included male child gender,younger caregivers, three or more children under the age of 5 living in the home, families in which a biologic child was not living with either parent, and scoring moderate or high on the Structured Decision Making Risk Tool(®). Caregiver involvement in intimate partner violence (IPV) and child enrollment in public health insurance appears to mitigate the risk of serious maltreatment.

    Estimating the case-fatality risk (CFR)—the probability that a person dies from an infection given that they are a case—is a high priority in epidemiologic investigation of newly emerging infectious diseases and sometimes in new outbreaks of known infectious diseases. The data available to estimate the overall CFR are often gathered for other purposes (e.g., surveillance) in challenging circumstances. We describe two forms of bias that may affect the estimation of the overall CFR—preferential ascertainment of severe cases and bias from reporting delays—and review solutions that have been proposed and implemented in past epidemics. Also of interest is the estimation of the causal impact of specific interventions (e.g., hospitalization, or hospitalization at a particular hospital) on survival, which can be estimated as a relative CFR for two or more groups. When observational data are used for this purpose, three more sources of bias may arise: confounding, survivorship bias, and selection due to preferential inclusion in surveillance datasets of those who are hospitalized and/or die. We illustrate these biases and caution against causal interpretation of differential CFR among those receiving different interventions in observational datasets. Again, we discuss ways to reduce these biases, particularly by estimating outcomes in smaller but more systematically defined cohorts ascertained before the onset of symptoms, such as those identified by forward contact tracing. Finally, we discuss the circumstances in which these biases may affect non-causal interpretation of risk factors for death among cases. PMID:26181387

    Crimean-Congo hemorrhagic fever (CCHF) is a tick borne viral disease which can also be transmitted by direct contact with blood or tissue specimens of infected animals or humans. We present a fatal case of CCHF, who was diagnosed after death, and describe the post-exposure management plan for the health care workers (HCWs) involved in her care. In total of 52 HCWs were involved in the patient's care and they were stratified into risk groups. Overall, 20 HCWs were grouped in high and intermediate risk groups, including the HCW with needle stick injury. High and intermediate risk groups were offered post exposure prophlaxis (PEP) with ribavirin. Fourteen of 20 HCWs started PEP, however 10 ceased after negative CCHF-PCR results. Negative CCHF-PCR results were reported for all HCWs at the 5th day of exposure. Side effects with PEP developed in 5 of HCWs and were mainly gastrointestinal complaints which reversed after drug discontinuation. All HCWs were followed for 14 days both clinically and with laboratory tests. None of the HCWs developed CCHF. PEP with ribavirin can be considered as a safe option in protection.

    We report a case of sudden death due to n-butane poisoning after the inhalation of anti-perspiration aerosol deodorant. The deceased was a 15-year-old boy who was found unresponsive on the road, and was pronounced dead after 1.25h. A spray can of anti-perspiration deodorant and vinyl bags were found in a thicket near the scene. An autopsy revealed pulmonary edema, cerebral edema and congestion of the organs. Using qualitative gas chromatography/mass spectrometry, the existence of n-butane was ascertained. The concentration of n-butane (in microl/ml or microl/g) was estimated to be 15.3 in the blood, 13.3 in the brain, 26.6 in the liver, 7.5 in the lung, and 13.6 in the kidney. These n-butane levels in the blood and in the tissues were higher than those of previous reports of death associated with n-butane inhalation. We concluded that the cause of death was n-butane poisoning and presumed that n-butane in the can of anti-perspiration aerosol deodorant induced fatal cardiac arrhythmia.

    2002-01-01

    In recent years recorded cases of plant poisoning have become rare, this may in part be due to the possibility of plant ingestion not being indicated at the beginning of an investigation. Aconitum napellus (aconite, Wolfsbane, Monkshood) is one of the most poisonous plants in the UK. It contains various potent alkaloids such as aconitine, isoaconitine, lycaconitine and napelline. Ingestion of Aconitum plant extracts can result in severe, potentially fatal toxic effects. This paper describes the analytical findings in a recent death in the UK. resulting from deliberate ingestion of Aconitum napellus extract. The concentrations of aconitine measured by HPLC-DAD in the post mortem femoral blood and urine were 10.8 micrograms/L and 264 micrograms/L, respectively. The aconitine concentration in the ante mortem urine was 334 micrograms/L and was estimated to be 6 micrograms/L in the ante mortem serum. Hence, accidental, suicidal or homicidal poisoning due to the ingestion of plant material remains a possibility and should be borne in mind when investigating sudden or unexplained death.

    Involvement of gastrointestinal tract by cytomegalovirus (CMV) is common. CMV infections mainly run their course without any clinical signs in immunocompetent hosts. In contrast, CMV can cause severe infections with serious consequences in a immunocompromised state typically associated with organ transplants, highly immunosuppressive cancer chemotherapy, advanced HIV infection or treatment with corticosteroids. The incidence and severity of these manifestations of CMV is directly proportional with the degree of cellular immune dysfunction, i.e., CD8+ Cytotoxic T-cell response. Clinical manifestations of CMV can become apparent in different situations including reactivation of CMV from latency, primary infection in a seronegative host, or exposure of a seropositive host to a new strain of CMV. As the clinical signs of CMV in immunodeficient patients are usually sparse, physicians should be highly vigilant about CMV infection, a treatable condition that otherwise is associated with significant mortality. Here we report a rare case of severe gastrointestinal CMV infection with sustained immunodeficiency secondary to treatment with steroids manifesting as fatal duodenal diverticular bleeding.

    This paper describes a case of an acute and fatal isoniazid-induced hepatotoxicity and provides a review of the literature. A 65-year-old female diagnosed with latent Mycobacterium tuberculosis infection was receiving oral isoniazid 300 mg daily. She was admitted to the hospital for epigastric and right sided flank pain of one-week duration. Laboratory results and imaging confirmed hepatitis. After ruling out all other possible causes, she was diagnosed with isoniazid-induced acute hepatitis (probable association by the Naranjo scale). After discharge, the patient was readmitted and suffered from severe coagulopathy, metabolic acidosis, acute kidney injury, hepatic encephalopathy, and cardiorespiratory arrest necessitating two rounds of cardiopulmonary resuscitation. Despite maximal hemodynamic support, the patient did not survive. A review of the literature, from several European countries and the United States of America, revealed a low incidence of mortality due to isoniazid-induced hepatotoxicity when used as a single agent for latent Mycobacterium tuberculosis infection. As for the management, the first step consists of withdrawing isoniazid and rechallenge is usually discouraged. Few treatment modalities have been proposed; however there is no robust evidence to support any of them. Routine monitoring for hepatotoxicity in patients receiving isoniazid is warranted to prevent morbidity and mortality. PMID:27648319

    Angioedema is an episodic swelling of the deep dermis, subcutis, and/or submucosal tissue due to an increase in local vascular permeability. Swelling may involve skin, respiratory, and gastrointestinal tracts. The most commonly involved areas are the periorbital region and the lips. Here we report a case of a fatal laryngeal obstruction due to angioedema likely caused by an angiotensin-converting-enzyme inhibitor. The decedent, a 58-year-old man, was witnessed developing sudden facial swelling and acute respiratory difficulties quickly followed by unresponsiveness. His past medical history suggested that this was his second episode of angioedema without urticaria. Postmortem examination revealed a complete laryngeal obstruction in the absence of infection, neoplasm, or autoimmune disease. Postmortem computed tomography of the head and neck showed a complete obstruction of the upper airway. Based on the current understanding of the pathophysiology of different types of angioedema, we will suggest a workup of angioedema without urticaria in the forensic setting and offer readers resources they can use in their practice.

    Although cobra envenomation continues to pose a threat to life and therefore constitutes a major cause of death in Africa, India, and Sri Lanka, the forensic pathology reports are not always histologically well documented or illustrated. The reports in the literature, although providing graphic evidence of the macroscopic appearances of the bite and its ensuing tissue necrosis, should the victim survive, often do not illustrate the histopathological findings to a sufficient degree. We present an unusual case of fatal envenomation by a rinkhals (Hemachatus haemachatus) in which the victim had been bitten a second time after a previous rinkhals' bite. Two issues therefore arose: (a) whether the histopathological findings in the spleen were an acute reaction to the snake bite or were due to immunostimulation as a consequence of the previously inflicted bite, and (b) the previously undocumented finding of extravasation of erythrocytes into the surrounding Virchow-Robin spaces in the brain, a finding usually associated with blunt head trauma and therefore interpreted as a cortical contusion hemorrhage by forensic pathologists.

    The Kidd blood group is clinically significant since the Jk antibodies can cause acute and delayed transfusion reactions as well as hemolytic disease of newborn (HDN). In general, HDN due to anti-Jk(b) incompatibility is rare and it usually displays mild clinical symptoms with a favorable prognosis. Yet, we apparently experienced the second case of HDN due to anti-Jk(b) with severe clinical symptoms and a fatal outcome. A female patient having the AB, Rh(D)-positive blood type was admitted for jaundice on the fourth day after birth. At the time of admission, the patient was lethargic and exhibited high pitched crying. The laboratory data indicated a hemoglobin value of 11.4 mg/dL, a reticulocyte count of 14.9% and a total bilirubin of 46.1 mg/dL, a direct bilirubin of 1.1 mg/dL and a strong positive result (+++) on the direct Coomb's test. As a result of the identification of irregular antibody from the maternal serum, anti-Jk(b) was detected, which was also found in the eluate made from infant's blood. Despite the aggressive treatment with exchange transfusion and intensive phototherapy, the patient died of intractable seizure and acute renal failure on the fourth day of admission. Therefore, pediatricians should be aware of the clinical courses of hemolytic jaundice due to anti-Jk(b), and they should be ready to treat this disease with active therapeutic interventions.

    In this case report, we present an evaluation of the distribution of postmortem concentrations of butyr-fentanyl in a fatality attributed principally to the drug. A man who had a history of intravenous drug abuse was found unresponsive on the bathroom floor of his home. Drug paraphernalia was located on the bathroom counter. Toxicology testing, which initially screened positive for fentanyl by enzyme-linked immunosorbent assay, subsequently confirmed butyr-fentanyl, which was then quantitated by gas chromatography-mass spectrometry-specific ion monitoring (GC-MS SIM) analysis following liquid-liquid extraction. The butyr-fentanyl peripheral blood concentration was quantitated at 58 ng/mL compared with the central blood concentration of 97 ng/mL. The liver concentration was 320 ng/g, the vitreous was 40 ng/mL, the urine was 670 ng/mL and the gastric contained 170 mg. Acetyl-fentanyl was also detected in all biological specimens tested. Peripheral blood concentration was quantitated at 38 ng/mL compared with the central blood concentration of 32 ng/mL. The liver concentration was 110 ng/g, the vitreous was 38 ng/mL, the urine was 540 ng/mL and the gastric contained <70 mg. The only other drug detected was a relatively low concentration of benzoylecgonine. The cause of death was certified as acute butyr-fentanyl, acetyl-fentanyl and cocaine intoxication, and the manner of death was certified as accident.

    A longitudinal study was carried out in the coastal lowlands coconut-cassava agro-ecological zone of Kaloleni Division, Coast Province, Kenya between June 1990 and December 1991 to estimate disease incidence and cause-specific case-fatality risk in an average of 120 cattle in 26 small-holder dairy herds kept in two grazing-management systems. East Coast fever (ECF) was the predominant disease diagnosed; the mean monthly incidence rate was 2.5 and 6.9% in animals < or = 18 months of age under stall-fed and herded-grazing systems, respectively. In cattle > 18 months of age, the monthly incidence rate was < 1%. The 6-month ECF incidence rate was 20+/-8% (S.E.) in the stall-feeding system compared with 39+/-7% in the herded-grazing systems. There was a gradual increase in antibody prevalence with age to over 90% in cattle over 18 months of age in herded-grazing systems, whilst less than a third of cattle in the stall-feeding systems were sero-positive at any age. Overall accumulated mortality to 18 months of age was estimated to be 56%. Annual mortality in cattle > 18 months averaged 9%. Cattle managed in the herded-grazing system had a 60% higher mortality, although not significantly so, than those fed in stalls. Deaths due to ECF accounted for over two-thirds of the deaths. ECF was then the major disease constraint to small-holder dairy production in the coconut zone of coastal Kenya. Clinical cases occur the whole year round (especially in young stock)--despite apparent tick control, and in both herded-grazing and stall-feeding system.

    Tuberculosis is emerging/re-emerging in captive elephant populations, where it causes morbidity and deaths, although no case of TB in wild African elephants has been reported. In this paper we report the first case of fatal TB in an African elephant in the wild. The infection with Mycobacterium tuberculosis was confirmed by post-mortem and histological examinations of a female sub-adult elephant aged >12 years that died in Tsavo East National Park, Kenya, while under treatment. This case is unique in that during its lifetime the elephant had contact with both humans and wild elephants. The source of the infection was unclear because the elephant could have acquired the infection in the orphanage or in the wild. However, our results show that wild elephants can maintain human TB in the wild and that the infection can be fatal.

    Agricultural fertilizers such as ammonium sulfate are widely used in house gardens as well as in agriculture, but few case reports or toxicological studies of ingested fertilizers have been reported. This paper investigates a fatal case of ammonium sulfate poisoning and demonstrates its clinical and biochemical findings in rabbits. An 85-year-old woman was found dead lying on the ground outside her house in the middle of March, but the autopsy could not determine the cause of her death. Examination at the police laboratory of the solution in the beer can found next to her showed that it was very likely ammonium sulfate. Our measurement showed a significant increase of ammonium and sulfate ions in serum and gastric contents. The cause of her death was determined as poisoning by ammonium sulfate. The total dose of 1500 mg/kg of ammonium sulfate was administered to three rabbits, all of which showed similar symptoms such as mydriasis, irregular respiratory rhythms, local and general convulsions, until they fell into respiratory failure with cardiac arrest. EEG showed slow, suppressive waves and high-amplitude slowing wave pattern, which is generally observed clinically in hyperammonemia in man and animal. There was a remarkable increase in the concentration of ammonium ion and inorganic sulfate ion in serum, and blood gas analysis showed severe metabolic acidosis. These results, mainly findings by EEG, have shown that a rapid increase in ammonium ions in blood can cause damaging the central nervous system without microscopic change. When the cause of death can not be determined, measurement of ammonium ion, inorganic ion and electrolytes in blood as well as in stomach contents at forensic autopsy is necessary.

    Despite the development in the identification of Nocardia spp., common challenges exist in the laboratory diagnosis and management of nocardiosis. We report two cases of disseminated nocardiosis in a patient with hematologic disorder and in a patient with systemic lupus erythematosus, where the cooperation between various specialists was essential to set up the adequate diagnosis of disseminated nocardiosis.

    TS-1 is an oral anti-cancer agent for gastric cancer with a high response rate and low toxicity. We report a case of long-term drug retention of TS-1 causing interstitial lung disease (ILD) as a fatal adverse reaction. A 65-year-old woman underwent a total gastrectomy with pathologic confirmation of gastric adenocarcinoma. She received 6 cycles of TS-1 and low-dose cisplatin for post-operative adjuvant chemotherapy followed by single-agent maintenance therapy with TS-1. After 8 months, the patient complained of a productive cough with sputum and mild dyspnea. A pulmonary evaluation revealed diffuse ILD in the lung fields, bilaterally. In spite of discontinuing chemotherapy and the administration of corticosteroids, the pulmonary symptoms did not improve, and the patient died of pulmonary failure. TS-1-induced ILD can be caused by long-term drug retention that alters the lung parenchyma irreversibly, the outcome of which can be life-threatening. Pulmonary evaluation for early detection of disease is recommended.

    Pandemic 2009 H1N1 (pH1N1) influenza viruses caused mild symptoms in most infected patients. However, a greater rate of severe disease was observed in healthy young adults and children without co-morbid conditions. Here we tested whether influenza strains displaying differential virulence could be present among circulating pH1N1 viruses. The biological properties and the genotype of viruses isolated from a patient showing mild disease (M) or from a fatal case (F), both without known co-morbid conditions were compared in vitro and in vivo. The F virus presented faster growth kinetics and stronger induction of cytokines than M virus in human alveolar lung epithelial cells. In the murine model in vivo, the F virus showed a stronger morbidity and mortality than M virus. Remarkably, a higher proportion of mice presenting infectious virus in the hearts, was found in F virus-infected animals. Altogether, the data indicate that strains of pH1N1 virus with enhanced pathogenicity circulated during the 2009 pandemic. In addition, examination of chemokine receptor 5 (CCR5) genotype, recently reported as involved in severe influenza virus disease, revealed that the F virus-infected patient was homozygous for the deleted form of CCR5 receptor (CCR5Δ32).

    The presence in rural areas of western Ecuador of scorpions in the genus Tityus capable of producing pediatric mortality is hereby evidenced. The medical significance of scorpions in Ecuador has been underestimated partly because of the clinically unimportant stings delivered by Centruroides margaritatus and Teuthraustes atramentarius, which have venom with low toxicity to vertebrates. Five intra-domiciliary cases of scorpion envenoming in victims aged between 1.9 and 16 years old, including one fatality, are reported from rural settings in forest areas of Chone (n = 2) and Flavio Alfaro (n = 3) counties, northern Manabí province, western Ecuador. Three cases were graded as Class II (moderate) and two in Class III (severe) envenoming. Manifestations showed characteristic autonomic nervous system hyper-stimulation and the fatality (a 1.9-year-old boy from Flavio Alfaro) was due to cardio-respiratory failure. Marked leukocytosis in four of the cases (21,800-31,800 cells/mm(3)), with notable neutrophilia (58-82%), suggests induction of a venom-mediated systemic inflammatory response-like syndrome. Specimens responsible for cases in Flavio Alfaro County, including the fatality, were classified as Tityus asthenes Pocock, accountable for severe scorpionism in Colombia. These findings demand implementation of control and therapeutic measures in affected areas in Ecuador, including evaluation of available scorpion antivenoms.

    A 59-year-old man was struck in the abdomen and later presented to the emergency room. His blood pressure dropped and eventually died 16h post trauma and just before emergency exploratory laparotomy. Autopsy revealed two polycystic kidneys and a giant polycystic liver with two ruptures. Blood (2225g) was observed in the peritoneum and the body-surface injury was minor. Genetic testing was performed to confirm that the man had an autosomal dominant polycystic kidney disease (ADPKD) complicated by polycystic liver disease (PLD). Autopsy, histopathology and medical history showed that the cause of death was the ruptures of liver cysts due to trauma. In this communication, we describe a fatal case and hope to increase awareness and recognition of PLD and ADPKD. We also wish to indicate that due to the fragile condition of liver cysts, trauma should be considered even if the body-surface injury is minor in fatal cases of PLD patient with a traumatic history.

    A parent who continuously physically abuses her/his child doesn’t aim to kill the child but commits an accidental filicide in a more violent outburst of anger. Fatal abuse deaths are prevented by recognition of signs of battering in time. Out of 200 examined intra-familial filicides, 23 (12%) were caused by child battering and 13 (7%) by continuous battering. The medical and court records of the victim and the perpetrator were examined. The perpetrator was the biological mother and the victim was male in 69 per cent of the cases. The abused children were either younger than one year or from two-and-a-half to four years old. Risk factors of the victim (being unwanted, premature birth, separation from the parent caused by hospitalization or custodial care, being ill and crying a lot) and the perpetrator (personality disorder, low socioeconomic status, chaotic family conditions, domestic violence, isolation, alcohol abuse) were common. The injuries caused by previous battering were mostly soft tissue injuries in head and limbs and head traumas and the battering lasted for days or even an year. The final assault was more violent and occurred when the parent was more anxious, frustrated or left alone with the child. The perpetrating parent was diagnosed as having a personality disorder (borderline, narcissistic or dependent) and often substance dependence (31%). None of them were psychotic. Authorities and community members should pay attention to the change in child’s behavior and inexplicable injuries or absence from daycare. Furthermore if the parent is immature, alcohol dependent, have a personality disorder and is unable to cope with the demands the small child entails in the parent’s life, the child may be in danger.

    This study estimated injury and illness rates, risk factors, and costs associated with construction work in Oregon from 1990-1997 using all accepted workers' compensation claims by Oregon construction employees (N = 20,680). Claim rates and risk estimates were estimated using a baseline calculated from Current Population Survey data of the Oregon workforce. The average annual rate of lost-time claims was 3.5 per 100 workers. More than 50% of claims were by workers under 35 years and with less than 1 year of tenure. The majority of claimants (96.1%) were male. There were 52 total fatalities reported over the period examined, representing an average annual death rate of 8.5 per 100,000 construction workers. Average claim cost was $10,084 and mean indemnity time was 57.3 days. Structural metal workers had the highest average days of indemnity of all workers (72. 1), highest average costs per claim ($16,472), and highest odds ratio of injury of all occupations examined. Sprains were the most frequently reported injury type, constituting 46.4% of all claims. The greatest accident risk occurred during the third hour of work. Training interventions should be extensively utilized for inexperienced workers, and prework exercises could potentially reduce injury frequency and severity.

    We describe a case of an acute lethal poisoning with hydrocarbons resulting from massive accidental inhalation of gasoline vapors. The victim, a 50-year-old man was found unconscious inside a control room for the transport of unleaded fuel. Complete autopsy was performed and showed evidence of congestion and edema of the lungs. Toxicological investigation was therefore fundamental to confirm exposure to fumes of gasoline. Both venous and arterial blood showed high values of volatiles in particular for benzene (39.0 and 30.4 μg/mL, respectively), toluene (23.7 and 20.4 μg/mL), and xylene isomers (29.8 and 19.3 μg/mL). The relatively low values found in the lungs are consistent with the fact that the subject, during the rescue, underwent orotracheal intubation followed by resuscitation techniques, while the low concentrations for all substances found in urine and kidneys could point to a death that occurred in a very short time after first contact with the fumes of gasoline.

    Using compensation records of Taiwan, we conducted a case-control study nested within a cohort of 77,846 active workers who experienced at least one incidence of non-fatal work-related injury between 1994 and 1996 in order to explore factors associated with risk of sustaining multiple non-fatal injuries in the workplace. Cases (n = 2,616) were workers with more than three incidences of non-fatal injury during the study period and controls (n = 3,974) were randomly sampled from workers who experienced only one incidence of non-fatal injury during the same period. Compared with construction workers, workers employed in mining and quarrying (OR = 2.7), manufacturing (OR = 1.2), commerce (OR = 1.6), transport, storage and communication (OR = 1.3) and social, personal and community service (OR = 1.4) were all at significantly elevated risk of multiple non-fatal injuries. Both age and wage showed a significant dose-response effect on the risk of developing multiple non-fatal injuries. The preliminary analysis suggests that workers in certain industries are at significantly elevated risks of multiple work-related non-fatal injuries, in particular those in the mining and quarry industries. Additionally, further preventive measures should be aimed at protecting older workers from such injuries and further studies would help provide more specific interpretations on the positive association between higher wage earning and risk of multiple non-fatal injuries.

    Most cases of gas gangrene caused by Clostridium species begin with trauma-related injuries but in rare cases, spontaneous gas gangrene (SGG) can occur when patients have conditions such as advanced malignancy, diabetes, or immunosuppression. Clostridium perfringens, a rare cause of SGG, exists as normal flora of skin and intestines of human. Adequate antibiotics with surgical debridement of infected tissue is the only curative therapeutic management. Mortality rate among adults is reported range of 67-100% and majority of deaths are occurred within 24 hours of onset. We experienced a case of SGG on the trunk, buttock and thigh in a neutropenic patient with acute lymphoblastic leukemia. His clinical course was rapid and fatal during pre-engraftment neutropenic period of allogeneic stem cell transplantation.

    The 11 March 2011 Tohoku-Oki earthquake (Mw9.0) caused approximately 19,000 casualties including missing persons along the entire coast of the Tohoku region. Three historical tsunamis occurred in the past 115 years preceding this tsunami. Since these tsunamis, numerous countermeasures against future tsunamis such as breakwaters, early tsunami warning systems and tsunami evacuation drills were implemented. Despite the preparedness, a number of deaths and missing persons occurred. Although this death rate is approximately 4 % of the population in severely inundated areas; 96 % safely evacuated or managed to survive the tsunami. To understand why some people evacuated immediately while others delayed; survivors were interviewed in the northern part of the Tohoku region. Our interviews revealed that many residents obtained no appropriate warnings and many chose to remain in dangerous locations partly because they obtained the wrong idea of the risks. In addition, our interviews also indicated that the resultant high casualties were due to current technology malfunction, underestimated earthquake size and tsunami heights, and failure of warning systems. Furthermore, the existing breakwaters provided the local community a false sense of security. The advanced technology did not work properly, especially at the time of the severe disaster. If residents had taken an immediate action after the major shaking stopped, most local residents might have survived considering that safer highlands are within 5 to 20 minute walking distance from the interviewed areas. However, the elderly and physically disabled people would still be in a much more difficult situation to walk such distance into safety. Nevertheless, even if these problems occur in future earthquakes, better knowledge regarding earthquakes and tsunami hazards could save more lives. People must take immediate action without waiting for official warning or help. To avoid similar high tsunami death ratios in the future

    Exact risk patterns in skydiving fatalities are not well known, but incomplete world injury data indicate that many are preventable. A comprehensive national material for Sweden of 37 skydiving fatalities 1964-2003 were reviewed to identify risk factors. In relation to jump volume, the period 1994-2003 had a fatality rate 11 times lower than 1964-1973. Student skydivers had the highest risk of fatal outcome, often caused by instability in freefall leading to unstable parachute activation with subsequent line entanglement, or parachute activation failure. Unintentional water landings also contributed to student fatality, with life jacket malfunctions, neglect to use life jackets, and automatic reserve parachute activation devices activated by water as aggravating factors. One-third of all fatalities had an inflated and operational parachute at some point prior to injury. A drastic worldwide increase in fatal landing incidents with fast wing parachutes during the 1990s did not occur in Sweden. Every fourth fatality caused by rapid deceleration against ground or water survived impact and died during transports or in hospitals. Rescue units and health care providers can improve management of skydiving incidents from knowledge about the incident and injury mechanisms we have described, and the skydiving community can target risk factors in preventive safety work.

    Fatalities attributed to powered circular saws appear to be vanishingly rare events with highly wounding and rapidly incapacitating effects. When they do occur, they are mainly self-inflicted in nature. We report the suicide committed by a 79-year-old man using a self-made circular table saw. Autopsy confirmed that the man received multiple heterogeneously distributed saw-type impacts to the head and neck resulting in complete amputation of the upper skull and partial beheading. Homemade or modified commercial sawing instruments and the resultant injuries pose a number of forensic challenges starting from the death scene investigation, continuing with technical examinations, and concluding with determining the manner of death. As with all deaths due to sharp force injuries, fatalities involving power tools such as chainsaws, circular, and band saws warrant a high degree of suspicion of criminal activity and require diligence during all phases of the death investigation.

    Progressive nodular histiocytosis (PNH) represents a very rare type of non-Langerhans cell histiocytosis. It is characterized by progressive appearance of papules and nodules without spontaneous resolution. We report a 60-year-old patient with novel clinical features in the form of extensive noduloulcerative lesions, ichthyotic patches, and laryngeal involvement culminating in fatal outcome prior to therapeutic intervention. Although the presenting features were baffling, histopathology and immunohistochemistry clinched the diagnosis of PNH. PMID:27990389

    2010-01-01

    Background Drowning is a major cause of morbidity and mortality for children, yet non-fatal drowning remains poorly understood. The aim of this study was to explore potential modifiable risk factors of non-fatal drowning among children in rural areas of China. Methods A cross-sectional survey was first conducted to obtain non-fatal drowning cases, and 7432 students in grades three to eight from 17 schools participated in the cross sectional survey. Of these, 805 students reported that they experienced non-fatal drowning in the previous year. Then 368 cases were selected randomly to participate in a 1:1 matched case-control study. Each drowning case was matched by one control with the same sex and similar age (the gap less than 2 years) who was selected randomly from the same class. Results Boys were more likely to be involved in non-fatal drowning. Non-fatal drowning most often happened in the afternoon (65.1%) and natural bodies of water were the most common sites of drowning (71.1%). Swimming, diving and playing in natural waters were the leading activities that preceded non-fatal drowning. The significant risk factors for non-fatal drowning were swimming in natural waters without adult supervision (OR = 3.40, 95% CI: 1.92-6.03), playing in or beside natural waters (OR = 2.08, 95% CI: 1.17-3.70) and poor swimming skills (OR = 2.74, 95% CI: 1.14-6.62). However, the following variables were protective factors: supervisor aged 30 years or over (OR = 0.20, 95% CI: 0.09-0.49) and no water activities (OR = 0.36, 95% CI: 0.18-0.70). Conclusions The reduction in dangerous water activities, swimming training and enhancement in supervision among children might decrease the risk of non-fatal drowning. PMID:20334694

    Acanthamoeba is the most common cause of granulomatous amebic encephalitis, a typically fatal condition that is classically described as indolent and slowly progressive. We report a case of Acanthamoeba encephalitis in a kidney transplant recipient that progressed to death within 3 days of symptom onset and was diagnosed at autopsy. We also review clinical characteristics, treatments, and outcomes of all published cases of Acanthamoeba encephalitis in solid organ transplant (SOT) recipients. Ten cases were identified, and the infection was fatal in 9 of these cases. In 6 patients, Acanthamoeba presented in a fulminant manner and death occurred within 2 weeks after the onset of neurologic symptoms. These acute presentations are likely related to immunodeficiencies associated with solid organ transplantation that result in an inability to control Acanthamoeba proliferation. Skin lesions may predate neurologic involvement and provide an opportunity for early diagnosis and treatment. Acanthamoeba is an under-recognized cause of encephalitis in SOT recipients and often presents in a fulminant manner in this population. Increased awareness of this disease and its clinical manifestations is essential to attain an early diagnosis and provide the best chance of cure.

    Linezolid is a synthetic antimicrobial agent of the oxazolidinone class with weak, nonspecific inhibitor of monoamine oxidase enzymes. Concomitant therapy with an adrenergic or serotonergic agent or consuming tyramine (>100 mg/day) may induce serotonin syndrome (SS). We present a case report of near-fatal adverse interaction between linezolid and escitalopram inducing SS in a 65-year-old woman with sepsis, under empirical antibiotic treatment. This report also summarizes the current relevant literature as identified via PubMed, EMBASE, and PsycINFO, supplemented with a manual search of cross references. PMID:24379509

    Two fatal cases of infantile rotavirus enteritis occurred in northern Italy in 2005. Both children were severely dehydrated, and death was related to severe cerebral edema. Histological examination demonstrated extensive damage of the intestinal epithelium, villous atrophy or blunting, and macrophage infiltration. The two rotavirus strains were of the G1P[8] type and the long electropherotype. The 2005 G1P[8] rotaviruses differed in the NSP4, VP3, VP4, and VP7 genes from G1P[8] rotaviruses circulating in 2004, suggesting the onset of a new G1P[8] strain in the local population.

    Injuries contribute significantly to the rising morbidity and mortality attributable to non-communicable diseases in the developing world. Unfortunately, active injury surveillance is lacking in many developing countries, including Kenya. This study aims to describe and identify causes of and risk factors for fatal injuries in two slums in Nairobi city using a demographic surveillance system framework. The causes of death are determined using verbal autopsies. We used a nested case-control study design with all deaths from injuries between 2003 and 2005 as cases. Two controls were randomly selected from the non-injury deaths over the same period and individually matched to each case on age and sex. We used conditional logistic regression modeling to identity individual- and community-level factors associated with fatal injuries. Intentional injuries accounted for about 51% and unintentional injuries accounted for 49% of all injuries. Homicides accounted for 91% of intentional injuries and 47% of all injury-related deaths. Firearms (23%) and road traffic crashes (22%) were the leading single causes of deaths due to injuries. About 15% of injuries were due to substance intoxication, particularly alcohol, which in this community comes from illicit brews and is at times contaminated with methanol. Results suggest that in the pervasively unsafe and insecure environment that characterizes the urban slums, ethnicity, residence, and area level factors contribute significantly to the risk of injury-related mortality.

    Fatalities due to attacks by tigers on humans are uncommon and are rarely described in the medico-legal literature. We herein present a forensic investigation in a unique case of a fatal tiger attack in the wild on a 35 year old female in India by an Indian Bengal tiger (Panthera tigris tigris). The attack resulted in two pairs of puncture wounds over the nape area with occult cervical spine injuries resulting from transfixing of spine due to the tiger canines; multiple puncture wounds, numerous scratches and abrasions consistent with the tiger claw injuries and injury to the right jugulocarotid vessels. This case outlines the characteristic injury pattern from such an attack along with the multiple sources of the tiger injuries. The analysis of these injuries might reveal the motivation behind the attack and the big cat species involved in the attack. A tiger injury is sometimes compared with a stab injury, as the patterned injuries due to a tiger bite are characterized by multiple penetrating, stab-like wounds. So, a special attention is paid toward establishment of the cause of death from bites by the animal teeth under unknown circumstances of trauma and to exclude the possibility of a homicide beyond reasonable doubt in such cases.

    The instances in which nosebleed is potentially fatal are those in which there is a history of recent head injury, severe arteriosclerotic cardiovascular disease or an underlying vascular tumor in the nasal chambers. Fatal nasal bleeding has not been reported in children. An awareness on the part of the physician of the potentially fatal significance of his patient's nosebleed is the very best insurance against such an event. Intelligent history-taking, careful physical and x-ray examination, generous sedation, precise local cauterization and packing, estimation of hemoglobin mass and a search for bleeding and clotting disorders are the best weapons of the physician called to treat epistaxis. These procedures, coupled with adequate blood replacement and an informed attitude toward surgical interruption of the blood supply to the bleeding region should forestall death from fatal nosebleed.

    Dengue is a public health problem, with several gaps in understanding its pathogenesis. Studies based on human fatal cases are extremely important and may clarify some of these gaps. In this work, we analyzed lesions in different organs of four dengue fatal cases, occurred in Brazil. Tissues were prepared for visualization in optical and electron microscopy, with damages quantification. As expected, we observed in all studied organ lesions characteristic of severe dengue, such as hemorrhage and edema, although other injuries were also detected. Cases presented necrotic areas in the liver and diffuse macro and microsteatosis, which were more accentuated in case 1, who also had obesity. The lung was the most affected organ, with hyaline membrane formation associated with mononuclear infiltrates in patients with pre-existing diseases such as diabetes and obesity (cases 1 and 2, respectively). These cases had also extensive acute tubular necrosis in the kidney. Infection induced destruction of cardiac fibers in most cases, with absence of nucleus and loss of striations, suggesting myocarditis. Spleens revealed significant destruction of the germinal centers and atrophy of lymphoid follicles, which may be associated to decrease of T cell number. Circulatory disturbs were reinforced by the presence of megakaryocytes in alveolar spaces, thrombus formation in glomerular capillaries and loss of endothelium in several tissues. Besides histopathological and ultrastructural observations, virus replication were investigated by detection of dengue antigens, especially the non-structural 3 protein (NS3), and confirmed by the presence of virus RNA negative strand (in situ hybridization), with second staining for identification of some cells. Results showed that dengue had broader tropism comparing to what was described before in literature, replicating in hepatocytes, type II pneumocytes and cardiac fibers, as well as in resident and circulating monocytes/macrophages and

Circulatory disturbs were reinforced by the presence of megakaryocytes in alveolar spaces, thrombus formation in glomerular capillaries and loss of endothelium in several tissues. Besides histopathological and ultrastructural observations, virus replication were investigated by detection of dengue antigens, especially the non-structural 3 protein (NS3), and confirmed by the presence of virus RNA negative strand (in situ hybridization), with second staining for identification of some cells. Results showed that dengue had broader tropism comparing to what was described before in literature, replicating in hepatocytes, type II pneumocytes and cardiac fibers, as well as in resident and circulating monocytes/macrophages and

    To better understand risk factors and populations at risk of childhood fatalities, a review of all records of childhood deaths (≤19 years) between 2000 and 2010 from New Mexico's statewide medical examiner was conducted. Annually, 313-383 childhood deaths were investigated (3820 total). Males and American Indians were overrepresented (62% and 20.4% of deaths, respectively). The most common manner of death was natural (44.8%), followed by accidental (31.4%), homicide (8.8%), suicide (8.8%), and undetermined (4.1%). Infants under 1 year of age accounted for 41.4% of deaths. Motor vehicle crashes were responsible for the majority of accidental deaths (69%), followed by unintentional overdoses (6.9%), and drowning (5.3%). Gunshot wounds, either intentional or unintentional, caused 10.7% of childhood deaths. Complete medico-legal investigation of childhood fatalities is needed to provide public health agencies with adequate data to evaluate and prevent childhood deaths.

    The emergence and reemergence of a serious infectious disease are often associated with a high case-fatality rate because of misdiagnosis and inappropriate or delayed treatment. The current reemergence of spotted fever rickettsiosis caused by Rickettsia rickettsii in Brazil has resulted in a high proportion of fatal cases. We describe two familial clusters of Brazilian spotted fever in the state of Minas Gerais, involving six children 9 months to 15 years of age; five died. Immunohistochemical investigation of tissues obtained at necropsy of a child in each location, Novo Cruzeiro and Coronel Fabriciano municipalities, established the diagnosis by demonstration of disseminated endothelial infection with spotted fever group rickettsiae. The diagnosis in the two fatal cases from Coronel Fabriciano and the surviving patient from Novo Cruzeiro was further supported by immunofluorescence serologic tests. PMID:14718082

    This report describes a case of fatal systemic toxoplasmosis in a 2.5-year-old mixed breed pregnant cat and its kittens. The pregnant cat was presented to the gynecology clinic with symptoms of dystocia. The ultrasound examination revealed the presence of five fetuses in the uterus, three of which were not alive, and consequently a cesarean section was performed. However, the mother cat and the remaining two live kittens died two and ten days after cesarean section, respectively. Pathologically, severe alveolar edema, tachyzoite-like structures in the alveolar macrophages and multifocal necroses in the lungs of mother cat were observed. An intense Toxoplasma gondii immunopositive reaction was observed in the cytoplasms of alveolar macrophages, bronchial and bronchiolar epithelia, necrotic foci in the lungs, and Kupffer cells of the liver. PCR analyses amplified T. gondii DNA in tissue samples of the mother cat and kittens. The present study provides strong evidence for a transplacental transmission of T. gondii infection with deadly outcome for the mother cat, fetuses and kittens. As to the authors' knowledge, this report is the first case of fatal congenital toxoplasmosis in domestic cats in Turkey.

    Invasive candidiasis has increased as nosocomial infection recently in cancer patients who receive systemic chemotherapy, and the timely risk assessment for developing such specific infection is crucial. Especially in those concomitantly with hypopituitarism, febrile neutropenia with candidiasis can cause severe stress and lead potentially to sudden fatal outcome when the temporal steroid coverage for the adrenal insufficiency is not fully administered. We report a 72-year-old male case diagnosed as non-small-cell lung cancer, Stage IIIA. He had received a steroid replacement therapy for the prior history of hypophysectomy due to pituitary adenoma with hydrocortisone of 3.3 mg/day, equivalent to prednisolone of 0.8 mg/day. This very small dosage of steroid was hardly supposed to weaken his immune system, but rather potentially led to an inappropriate supplementation of his adrenal function, assuming that the serum sodium and chlorine levels decreased. On Day 6 of second cycle of chemotherapy with carboplatin and paclitaxel, he developed sudden febrile neutropenia, septic shock and ileus, leading to death. After his death, the venous blood culture on Day 7 detected Candida albicans. Autopsy findings showed a massive necrotizing enterocolitis with extensive Candida invasion into submucous tissue. In conclusion, this case may suggest that (i) immediate initiation of antifungal therapy soon after the careful risk assessment of Candida infection and (ii) adequate administration of both basal steroid replacement therapy and temporal steroid coverage for febrile neutropenia might have improved his fatal outcome.

    This article describes the biochemical and chemical-toxicological investigations into the properties of the pericardial fluid designed to improve the effectiveness of forensic medical examination of the cases of fatal drug poisoning. The objectives of the study were the detection and determination of the type of narcotic substances in the pericardial fluid, evaluation of the quantitative changes in enzyme activities (AST, ALT and CPK) in the pericardial fluid, and the development of the criteria for the forensic medical diagnostics of fatal drug poisoning. The materials used in the study were the pericardial fluid and blood taken during forensic medical examination of 247 corpses of men (87.04%) and women (12.96%) at the age from 13 to 35 years who died from different causes. They were divided into two groups. The study group was comprised of 142 subjects who died from drug poisoning, the control group consisted of 105 subjects who died from other causes. The methods used to study the pericardial fluid included gas-liquid chromatography to detect the presence and the type of the poisonous drugs, as well as biochemical and colorimetric methods to determine the amount of enzymes AST, ALT, and CPK. The study revealed no traces of drugs or their metabolites in the pericardial fluid from the 105 control corpses. Positive results of the forensic drug tests were obtained in all the 142 cases of the study group. The changes in the parameters and the biochemical composition of pericardial fluid and blood in fatal drug poisoning were reliably established including the alteration of the enzyme levels, such as AST, ALT, and CPK. In the control group, the quantitative parameters of the enzyme activities did not exceed the normal values whereas in the study group a significant increase of AST, ALT, and CPK levels in the pericardial fluid and blood in comparison with the normal values was documented. Conclusion: the results obtained in the studies of both groups provide a basis

    Forty-four fatal cases of Rocky Mountain spotted fever (RMSF) occurring in 1974 were compared with 50 nonfatal cases of similar age, sex, date of onset, and place of occurrence. Diagnosis and initiation of treatment in fatal cases were substantially delayed compared with nonfatal cases. Several reasons for this delay were identified: (1) the rash appeared later in the course of illness in the fatal cases, often not until the patient was terminal, (2) a history of tick bite was less often obtained during life or obtained late in the clinical course in fatal cases, and (3) initial nonspecific symptoms or unexpected symptoms led to an initial diagnosis of more common diseases. Only two fatal cases were treated with either tetracycline or chloramphenicol before the sixth day of illness. Presumptive diagnosis of RMSF and initiation of tetracycline therapy before onset of rash may be necessary to reduce mortality.

    A 37-year-old man died as a result of exposure to carbon monoxide within an apartment. An investigation of the apartment showed no gas appliances or gas supply to the apartment and no evidence of any combustion event to any part of the apartment or roof space. Inhalation of dichloromethane was excluded. Heating to the apartment was found to be via an electrical storage heater, the examination of which revealed that the cast-iron core and insulating material showed evidence of heat damage with significant areas devoid of carbon. This electric storage heater is hypothesized to be the source of carbon for the fatal production of carbon monoxide within the apartment.

    Although diarrhea is the most commonly reported pediatric illness in the United States, mortality is usually a rare and unexpected event. We report the case of a healthy 13-month-old male that succumbed to a diarrheal illness of unclear etiology. Presenting signs included frequent nonbloody stools that progressed to frankly bloody stools over 72 hours. Associated symptoms included fever, tenesmus, relief with stool passage, and significant fatigue. On examination, the patient appeared tired and lay with legs curled toward his chest. The abdominal exam was remarkable for hypoactive bowel sounds, diffuse tenderness to palpation without guarding or rebound pain, and intermittent prolapse of rectal tissue. Abdominal plain films demonstrated a paucity of bowel gas, especially in the rectum; and ultrasound revealed thickening of bowel loops in the left lower quadrant. Abdominal computed tomography scan showed decreased enhancement of the mucosa of the rectosigmoid colon. The patient deteriorated rapidly with cardiorespiratory arrest occurring 48 hours after admission. Despite a protracted effort at cardiopulmonary resuscitation, perfusing heart rate or rhythm could not be reestablished. Autopsy revealed infarction and necrosis of the rectosigmoid colon with invasive gram-negative bacilli. Here we present his perplexing case, diagnostic evaluations, and suggest a unifying diagnosis.

    We investigated the associations between types of diabetes and ICH incidence and case-fatality after ICH, in a retrospective cohort study of people aged 40-89 years in Scotland 2004-2013 using linkage of population-based records of diagnosed diabetes, hospital discharges and deaths. We calculated ICH incidence and 30-day case-fatality after hospital admission for ICH and their relative risks (RR) and 95% confidence intervals (95%CI) for people with type 1 or type 2 diabetes compared to people without diabetes adjusting for age, sex and socio-economic status (SES). There were 77, 1275 and 9778 incident ICH and case-fatality (95% CI) was 44 (33, 57)%, 38 (35, 41)% and 36% (35, 37)% in people with type 1, type 2 and without diabetes, respectively. In comparison to the non-diabetic population, type 1 diabetes was associated with a higher incidence of ICH (1.74, 95%CI 1.38-2.21) and case fatality after ICH (1.35, 95%CI 1.01-1.70), after adjustment for age, sex and SES. Small increases in ICH incidence 1.06, 95%CI 0.99-1.12) and case-fatality 1.04, 95%CI 0.96-1.13) in people with type 2 diabetes compared to non-diabetic people were not statistically significant.

    Introduction: Measles is affecting millions of people in the developing countries particularly in India with significant morbidity and responsible for thousands of death in spite of having a safe, effective, and cheap vaccine. Pulmonary complications account for 90% measles-related death. The objectives of this study were to describe age distribution, clinical features, complications, and clinical outcomes of measles cases in a referral infectious disease hospital of West Bengal. Methods: We conducted a retrospective descriptive study including 584 patients and collected information from record section on demographics, clinical features, complications, and clinical outcomes using data abstraction form. Results: The mean age of 584 measles cases was 3.7 years (±1.2 years). The most common complication was pneumonia (149 cases) followed by diarrhea and encephalopathy. Very severe pneumonia occurred in 34 cases requiring intensive care out of which 13 patients died. The average duration of stay in the hospital was 5.7 days (±3.2 days). Surprisingly, 45 cases admitted to this hospital were <9 months of age with subsequent death in 5 cases. Conclusion: Substantial number of measles cases was seen in zero to <9 months of age group and fatality due to complication was more among them.

    Since 1996, states have been implementing and enhancing their graduated driver licensing (GDL) programs. Increased licensing restrictions could steer new drivers to bypass training and licensing altogether. Unlicensed driving is associated with increased fatal crashes and high-risk behaviors that have been shown to adversely affect passenger safety behaviors like restraint use. The objective of this study was to assess the impact of varying state level GDL programs on rates of unlicensed driving and on passenger restraint use. De-identified data from the National Highway Traffic Safety Administration’s Fatality Analysis Reporting System from years 1996–2010 was analyzed. Fatal crashes involving drivers (15–24 yrs) and their passengers (15–24 yrs) were included. Using a validated system, each state’s GDL laws at a given month were rated as poor, marginal, fair, or good. The association between GDL strength and unlicensed driving was analyzed graphically and by chi-square test. Multivariate logistic regression with generalized estimating equations were undertaken to assess the relationship between GDL strength and passenger restraint use. From January 1996 to December 2010, 26,504 (23.4%) passengers were involved in fatal crashes taking place in states with GDL programs rated poor, 21,366(18.9%) marginal, 33,603 (29.6%) fair, and 31,903 (28.1%) good. Rates of unlicensed driving ranged from 16.4% in state-months rated marginal versus 21.5% in state-months rated good (p<0.001). In the multivariate model, compared to states with poor GDL ratings, each additional rating boost was associated with an increased odds of passenger safety restraint use (OR 1.15, 95% CI 1.13–1.18). Our findings suggest that stronger GDL law can mitigate passenger risk in fatal crashes by encouraging passenger restraint use. Our study provides evidence that stronger legislation in these states may reduce overall risk to young drivers and their passengers. PMID:24406949

    Abstract We report on four patients with fatal influenza A(H1N1)pdm09 and dengue virus coinfections. Clinical, necropsy and histopathologic findings presented in all cases were characteristic of influenza-dengue coinfections, and all were laboratory-confirmed for both infections. The possibility of influenza and dengue coinfection should be considered in locations where these two viruses’ epidemic periods coincide to avoid fatal outcomes. Dengue is a mosquito-borne viral infection caused by one of the four dengue viruses (DENV-1 to 4). Each of these viruses is capable of causing nonspecific febrile illnesses, classic dengue fever and dengue haemorrhagic fever (Gubler 1998). As a result, dengue is often difficult to diagnose clinically, especially because peak dengue season often coincides with that of other common febrile illnesses in tropical regions (Chacon et al. 2015). In April 2009, a new virus, influenza A/H1N1/pandemic (FluA/H1N1/09pdm), caused a severe outbreak in Mexico. The virus quickly spread throughout the world, and in June 2009, the World Health Organization declared a pandemic (WHO 2010). In Brazil, the first laboratory confirmed case of FluA/H1N1/09pdm was in July 2009 (Pires Neto et al. 2013). The state of Ceará, in Northeast Brazil, is a dengue endemic area. In this state, the virus influenza A(H1N1)pdm09 has circulated since 2009, and through the first half of 2012, 11 deaths caused by the virus were confirmed (Pires Neto et al. 2013). The influenza and dengue seasons in Ceará overlap, which led to diagnostic difficulties. We report four cases of laboratory-confirmed coinfection of deadly influenza A(H1N1)pdm09 with DENV, which occurred during the dengue and influenza season in 2012 and 2013 in Ceará. PMID:27598244

    Strongyloides stercoralis hyperinfection syndrome is a rare but fatal disease, which occurs commonly in immunocompromised patients. Strongyloidiasis among patients with chronic kidney disease is rarely reported.A 55-year-old Chinese male presented to hospital with diarrhea and abdominal pain. He developed acute respiratory failure and progressed to diffuse alveolar hemorrhage owing to disseminated strongyloidiasis immediately. The bronchoalveolar lavage revealed filariform larvae of Strongyloides stercoralis.This patient was diagnosed with Strongyloides hyperinfection syndrome. Although albendazole, mechanical ventilator support, fluid resuscitation, vasopressor support, extracorporeal membrane oxygenation, hydrocortisone, and broadspectrum antimicrobials were actively used, the patient eventually died.Similar cases in patients with chronic kidney disease in the literature are also reviewed. Through literature review, we recommend that strongyloidiasis should be routinely investigated in patients with chronic kidney disease who will undergo immunosuppressive therapy.

    Clostridium chauvoei is a gram positive, spore building bacterium that causes blackleg, a mostly fatal disease in cattle and other ruminants. Although the disease is common, little is known on the epidemiology of blackleg. As infection occurs through the environment, the risk of blackleg might be increased in areas with a specific climate or soil type. Therefore, the objective of the present study was to identify spatial and temporal clusters in the incidence of blackleg in the province of Styria, Austria. Data were collected within the governmentally delivered blackleg control program which includes vaccination of cattle with access to known blackleg pastures and compensation for fallen stock. Between 1986 and 2013, 1448 suspect blackleg cases were reported to official veterinarians; with blackleg confirmed through bacteriology in 266 cases (18%). The number of confirmed blackleg cases was highest in 2011 (25 cases) and lowest in 2004 (2 cases). Mean annual blackleg incidences varied considerably between different municipalities from 0 cases in most of the Southern parts of the province to 584 cases/1,000,000 cattle in some Northwestern municipalities. The spatio-temporal analysis identified one high risk cluster in the Northwest where cattle had 9.56 times the risk to develop blackleg compared to those in Northern and Northeastern parts of the province. Furthermore, a low-risk cluster was identified in the southeastern part of the province, where cattle had a relative risk of 0.015 to die of blackleg. No temporal or spatio-temporal clusters were identified. Results of the present study suggest that blackleg cases are clustered within certain geographic areas which might be due to soil type and water permeability. Results of this study should be used to motivate farmers to vaccinate cattle against Clostridium chauvoei in known areas with high risk.

    BACKGROUND: Edwardsiella tarda bacteremia (ETB) can be a fatal disease in humans. OBJECTIVES: To determine the significant risk factors associated with death caused by ETB, and to examine the geographical, seasonal, environmental and dietary factors of the disease. METHODS: A retrospective, observational, case control study was performed. The PubMed MEDLINE and Japanese Medical Abstract Society (www.jamas.or.jp) databases were searched for ETB case reports and meeting abstracts. In additon, retrospective chart reviews of patients with ETB at the Tokyo Women’s Medical University Hospital (Tokyo, Japan) were conducted to evaluate the risk factors associated with death using multivariate analyses. RESULTS: The literature search yielded 46 publications, comprising 72 cases from the English (n=30), French (n=1), Spanish (n=1) and Japanese (n=14) literature. Five cases at the Tokyo Women’s Medical University Hospital were also included. Of the included 77 cases, the mean age was 61 years and 39% of patients were female; 77.2% of the cases occurred between June and November, and 45.5% were reported in Japan. Dietary factors (raw fish/meat exposure) were reported for 10.4% of patients and 12.9% reported environmental (ie, brackish water) exposure. The overall mortality rate was 44.6%; however, this rate increased to 61.1% for ETB patients with soft tissue infections. Liver cirrhosis was determined to be an independent risk factor associated with death (OR 12.0 [95% CI 2.46 to 58.6]; P=0.00213) using multivariate analyses. DISCUSSION: To our knowledge, the present analysis was the first and largest multi-language review of ETB. Clinical characteristics of ETB resemble those of Aeromonas, typhoid fever and Vibrio vulnificus infections, in addition to sharing similar risk factors. CONCLUSION: ETB should be categorized as a severe food- and waterborne infection, which results in high mortality for patients with liver cirrhosis. PMID:26744588

    In order to determine the comparative toxicology and systemic disease of cases of death due to methadone and heroin toxicity, 1193 coronial cases of opioid overdose that occurred in New South Wales, Australia between 1 January 1998 and 31 December 2007 were inspected. These comprised 193 cases in which cause of death involved methadone toxicity (METH) and 1000 cases in which cause of death involved heroin toxicity in the absence of methadone (HER). METH cases were significantly more likely to have benzodiazepines (63.7% vs. 32.2%), and less likely to have alcohol (23.6% vs. 42.7%) detected. METH cases were significantly more likely to be diagnosed with pre-existing systemic pathology (94.3% vs. 79.9%), and multiple organ system pathology (68.8% vs. 41.4%). Specifically, METH cases were more likely to have cardiac (58.9% vs. 34.5%), pulmonary (53.6% vs. 30.9%), hepatic (80.7% vs. 62.8%) and renal (25.0% vs. 9.5%) disease. Given the notable differences in toxicology and disease patterns, great caution appears warranted in prescribing benzodiazepines to methadone users, and regular physical examinations of methadone treatment patients would appear clinically warranted.

This report illustrates an unusual course of a fast progression of the bronchiectasis due to BMT. Case description. A 33-year-old female was diagnosed with acute myeloid leukaemia. An allogeneic BMT was performed. One month after the transplantation, acute GVHD with skin involvement occurred. Treatment with prednisolone and mycophenolate mofetil (MMF) has been started. Nine months later, the patient was examined by a pulmonologist due to progressive dyspnoea. A pulmonary computed tomography (CT) scan showed normal parenchyma of the lungs and no changes to the bronchi. A CT scan performed 7 months later revealed bronchiectasis for the first time. No clinical response was associated with the treatment and the patient’s respiratory status progressively deteriorated. During the final hospitalization, a CT scan performed 1 year later revealed huge cystic bronchiectasis in both lungs. Despite the prophylaxis and treatment of GVHD and aggressive antimicrobial therapy, the patient died one year after the diagnosis of bronchiectasis. Conclusions. This case demonstrates that a fast and fatal course of bronchiectasis, that occurs after BMT, should always be considered as a possible manifestation of chronic graft versus host disease (cGVHD) following allogeneic BMT.

    In the Western world, cases of fatal child neglect due to starvation are extremely rare. When they do occur, particularly at the hands of a parent, such crimes are considered to be caused by mental disorders or personality disorders with severe affective impairment. The present report describes the peculiar case of a couple with a total of four children to care for, who starved a 16-month-old female to death, while all the other children were found to be healthy. After a forensic psychiatric assessment of their criminal responsibility, the couples were both judged guilty and sentenced to 30 years in prison. After a brief overview of the scientific knowledge about filicide, the authors propose a framework that may help to understand and explain the motivations underlying this dreadful crime that shocked the nation, and emphasize the role of the forensic psychiatric investigation into cases of filicide, which may contribute to gain a greater insight into the different motivational factors underlying this phenomenon.

    Tolperisone (Mydocalm) is a centrally acting muscle relaxant with few sedative side effects that is used for the treatment of chronic pain conditions. We describe three cases of suicidal tolperisone poisoning in three healthy young subjects in the years 2006, 2008 and 2009. In all cases, macroscopic and microscopic autopsy findings did not reveal the cause of death. Systematic toxicological analysis (STA) including immunological tests, screening for volatile substances and blood, urine and gastric content screening by GC-MS and HPLC-DAD demonstrated the presence of tolperisone in all cases. In addition to tolperisone, only the analgesics paracetamol (acetaminophen), ibuprofen and naproxen could be detected. The blood ethanol concentrations were all lower than 0.10 g/kg. Tolperisone was extracted by liquid-liquid extraction using n-chlorobutane as the extraction solvent. The quantification was performed by GC-NPD analysis of blood, urine and gastric content. Tolperisone concentrations of 7.0 mg/l, 14 mg/l and 19 mg/l were found in the blood of the deceased. In the absence of other autopsy findings, the deaths in these three cases were finally explained as a result of lethal tolperisone ingestion. To the best of our knowledge, these three cases are the first reported cases of suicidal tolperisone poisonings.

    We present a case of a 22-year-old male, who was found inside the cage of Himalayan black bears in the Belgrade Zoo. The victim attended the Belgrade Beer festival the previous night, drinking a lot of beer and acting aggressively. A medico-legal autopsy was performed at the Institute of Forensic Medicine in Belgrade. Autopsy findings showed numerous excoriations all over the body surrounded by bruises, as well as spindle-shaped, oval, and partly irregular wounds of variable size, large defects of skin and subcutaneous soft tissue, fractures of the thyroid and cricoid cartilage, and fracture of ribs. Postmortem toxicological analysis revealed the presence of ethanol in vitreous humor and urine and 11-nor Δ9 tetrahydrocannabinolic acid found in the urine. We discussed similar cases from the available literature in different regions of the world. In conclusion, we pointed out that the presented case does not follow the general pattern of Himalayan bear attacks.

    Two suspected hantavirus pulmonary syndrome (HPS) cases from Bolivia occurred in May and July 2000 and were confirmed by enzyme-linked immunosorbent assay (ELISA)-ANDES using N-Andes recombinant antigen serology. Clot RNAs from the two patients were subjected to reverse transcription-polymerase chain reaction (PCR) amplification and sequencing. We describe two characterized cases of HPS. One was caused by infection with Bermejo virus and the other with Andes Nort viral lineage, both previously obtained from Oligoryzomys species. This is the first report of molecular identification of a human hantavirus associated with Bermejo virus.

    We report a girl who developed severe and fatal hyperkalemia following rapid and massive blood transfusion during surgery. She was 7-year-old, 20-kg in weight, and received wide resection of the femoral bone with custom prosthesis implant because of malignant femoral osteosarcoma. During the procedure, bleeding was active and profuse and amounted to about 3,000 mL in 4 h, eventuating in shock. Despite rapid transfusion with 15 units of packed red blood cells (RBC) still she remained hypotensive and hypovolemic. When we switched to give her whole blood, actually 100 mL having been given, widening of QRS complex followed immediately by cardiac arrest developed. Cardiopulmonary resuscitation although started at once was unsuccessful. At this juncture, arterial blood gas analysis showed acidosis and severe hyperkalemia (10.3 mmol/L), possibly resulting from transfusion of blood of older storage. The case reminded us once again the importance and necessity of the use of potassium-low blood component (fresh, saline-washed RBCs) in case of massive and rapid blood transfusion especially in pediatric patients with hypovolemia and low cardiac output.

    11-nor-9-carboxy-Delta9-tetrahydrocannabinol (THC-COOH) distributions in postmortem specimens are rarely reported. Fifty New Jersey State Medical Examiner's cases in which automobile accident deaths suspected of involving marijuana intake were studied for the distributions of THC-COOH in postmortem urine, blood, vitreous humor, and bile specimens. Cases were selected based on immunoassay (TDx) urine test results. If the preliminary urine test indicated the presence of THC-COOH (apparent THC-COOH concentration > or = 20 ng/mL), urine, heart blood, vitreous humor, and bile specimens from the case were analyzed for THC-COOH concentrations by gas chromatography-mass spectrometry. The mean, standard deviation, and range of THC-COOH in heart blood, urine, and bile found in these 50 cases were 0.081, 0.082, and 0.016-0.33 microg/mL; 0.314, 0.415, and 0.044-2.33 microg/mL; and 12.9, 11.4, and 1.03-43.7 microg/mL, respectively. THC-COOH was absent (detection limit, 1 ng/mL) or at low concentration (< 10 ng/mL) in vitreous humor specimens. The mean, standard deviation, and range of the bile-to-blood and urine-to-blood ratios were 242, 196, and 17.2-888 and 4.70, 4.05, and 1.14-19.2, respectively. The highest concentrations of THC-COOH were found in bile and the lowest in vitreous humor. These findings are consistent with the high hydrophobicity nature of THC-COOH and further suggest that bile is the specimen of choice for detecting low level of THC-COOH in postmortem cases.

    Aluminum phosphide is one of the commonest poisons encountered in agricultural areas, and manner of death in the victims is often suicidal and rarely homicidal or accidental. This paper presents an unusual case, where two humans (owner and housemaid) and eight dogs were found dead in the morning hours inside a room of a house, used as shelter for stray dogs. There was allegation by the son of the owner that his father had been killed. Crime scene visit by forensic pathologists helped to collect vital evidence. Autopsies of both the human victims and the dogs were conducted. Toxicological analysis of viscera, vomitus, leftover food, and chemical container at the crime scene tested positive for aluminum phosphide. The cause of death in both humans and dogs was aluminum phosphide poisoning. Investigation by police and the forensic approach to the case helped in ascertaining the manner of death, which was accidental.

    Introduction Endoscopic retrograde cholangiopancreaticography has been the treatment of choice for stones in the common bile duct. Although the procedure is usually safe, procedure-related complications do occur. Case presentation A case of pancreatitis following endoscopic retrograde cholangiopancreaticography is described in a 55-year-old woman. After an uneventful recovery the patient's condition deteriorated rapidly 16 days after the endoscopic retrograde cholangiopancreaticography, and the patient died within 1 hour. Post-mortem examination revealed massive intrapulmonary fat embolism. The complications of endoscopic retrograde cholangiopancreaticography and pancreatitis are described. Conclusion Fat embolism can occur after the remission of pancreatitis and pancreatic necrosis may be overlooked on contrast-enhanced computed tomography scanning. PMID:18577211

    Caffeine, 1,3,7-trimethylxanthine, is the most widely consumed legal stimulant. The most potent form is over the counter oral tablets. The estimated average daily adult caffeine consumption is 300 mg. Rarely, serious toxicities such as seizure and cardiac arrhythmias have caused death. Caffeine concentrations of 80 mg/L are considered lethal. Cases investigated over 10 years by the Office of the Chief Medical Examiner for the State of Maryland (OCME) whose cause of death was solely or in combination due to caffeine intoxication were reviewed. A total of eight adult cases were identified consisting of two suicides and six undetermined manners. The average postmortem caffeine concentration was 140.4 mg/L. This is the largest case series reported to date of lethal caffeine intoxication. Large doses of prescription medications and/or over the counter medications were abused. No overdoses were from consumption of caffeine-containing foods. Comprehensive postmortem toxicological testing should test for caffeine to capture these rare deaths.

    We report 2 cases of accidental intrathecal vincristine administration. These injections were scheduled as intravenous injections of vincristine at the same time as other intrathecal drugs were scheduled. The mistakes were recognized immediately after administration, and a lumbar puncture was performed to lavage the cerebrospinal fluid (CSF) immediately after the incident. However, both cases developed progressive sensorimotor and radiculo-myelo-encephalopathy and the patients died 3 and 6 days after the incidents due to decerebration. A number of cases of accidental intrathecal vincristine administration have occurred in recent years in other settings, and we add our events to emphasize the need for a preventative and strictly followed protocol in oncology treatment units to prevent further unnecessary deaths. The best 'cure' for mistakenly administered vincristine via lumbar puncture is prevention, which can be improved by strict adherence to a comprehensive guideline. Oncologic treatment centers should be aware of this guideline and evaluate their protocol for vincristine administration to prevent future incidents. Based on our past experiences, we strongly recommend 'time-independent' procedures to prevent this type of incident.

  15. Rapidly progressing, fatal and acute promyelocytic leukaemia that initially manifested as a painful third molar: a case report

    PubMed Central

    2009-01-01

    Introduction Acute promyelocytic leukaemia, an uncommon and devastating subtype of leukaemia, is highly prevalent in Latin American populations. The disease may be detected by a dentist since oral signs are often the initial manifestation. However, despite several cases describing oral manifestations of acute promyelocytic leukaemia and genetic analysis, reports of acute promyelocytic leukaemia in Hispanic populations are scarce. The identification of third molar pain as an initial clinical manifestation is also uncommon. This is the first known case involving these particular features. Case presentation A 24-year-old Latin American man without relevant antecedents consulted a dentist for pain in his third molar. After two dental extractions, the patient experienced increased pain, poor healing, jaw enlargement and bleeding. A physical examination later revealed that the patient had pallor, jaw enlargement, ecchymoses and gingival haemorrhage. Laboratory findings showed pancytopaenia, delayed coagulation times, hypoalbuminaemia and elevated lactate dehydrogenase. Splenomegaly was detected on ultrasonography. Peripheral blood and bone marrow analyses revealed a hypercellular infiltrate of atypical promyelocytic cells. Cytogenetic analysis showing genetic translocation t(15;17) further confirmed acute promyelocytic leukaemia. Despite early chemotherapy, the patient died within one week due to intracranial bleeding secondary to disseminated intravascular coagulation. Conclusion The description of this unusual presentation of acute promyelocytic leukaemia, the diagnostic difficulties and the fatal outcome are particularly directed toward dental surgery practitioners to emphasise the importance of clinical assessment and preoperative evaluation as a minimal clinically-oriented routine. This case may also be of particular interest to haematologists, since the patient's cytogenetic analysis, clinical course and therapeutic response are well documented. PMID:19946580

    Anthrax is a recessive infectious disease caused by the bacterium Bacillus anthracis, and is primarily a zoonotic disease. Until recently, Bacillus anthracis infections were relatively infrequent and confined to agrarian communities in underdeveloped countries. No anthrax cases were reported in Changchun City in the past few decades until a male patient from the Inner Mongolia Autonomous Region presented the anthrax disease manifestation. This paper describes an anthrax patient's diagnosis, isolation and treatment which involved institutions in two different Chinese provinces; the foci epidemiological investigation alongside with the outbreak management process, which is of great significance to control the spread of the recessive infection is also described.

    Giant cell arteritis ( GCA) is an inflammatory vasculopathy affecting large and middle-sized vessels , specifically cranial arteries derived from carotid artery. Isolated extracranial vessel involvement can occur. Interest in extravascular manifestations is recently increasing because of diffusion of sensitive and specific imaging tools such as 18FDG PET TC . Patients have an increased relative risk of severe infection. Listeria monocytogenes infection risk is increased, and vascular system involvement and graft infection have been, even though rarely, reported. We report the case of a 72 year old woman with a history of suspected giant cell aortitis , previous surgical treatment of ascendant and descendant thoracic aortic aneurysm, presenting 7 year after TEVAR with thoracic pain , fever, inflammatory indexes increase, leukocytosis, listeria sepsis and rapidly increasing type I proximal endoleak on CT. 18 FDG PET positivity was associated. Endograft listeria infection on aortitis reactivation was suspected but death for multi-organ failure and absence of autopsy data couldn't confirm diagnosis . Listeria vascular graft infection has been reported previously. Giant cell arteritis is a predisposing condition. We report the first case of endograft infection by listeria monocytogenes in a patient with positive history of suspected giant cell aortic aneurysm.

    We report a 74-year-old man with diabetes mellitus type 2 and hypertension, who recently underwent coronary bypass surgery due to severe triple vessel disease receiving cardiological and combined antidiabetic therapy, including metformin 4 g/day. He was admitted with abdominal pain, nausea, vomiting, diarrhea and loss of consciousness. At admission, he was disoriented and agitated with signs of poor perfusion. His blood pressure was 80/70 mmHg, pulse rate 40 beats/min, respiratory rate 20-breaths/min, and axillary temperature 35 °C. Biochemical profile revealed an extreme hyperkalemia of 15.4 mEq/L (double checked), elevated creatinine, uremia and brain natriuretic peptide; hypoglycemia (blood glucose 68 mg/dl) and normal C Reactive Protein. Arterial blood gases revealed severe lactic acidemia. The electrocardiogram showed sinus bradycardia, simple AV block, widened QRS with prominent T wave and prolonged QT. He was admitted to the Intensive Care Unit (ICU) with the suspicion of lactic acidosis associated with metformin, receiving fluid management, intravenous hypertonic glucose plus insulin and sodium bicarbonate, mechanical ventilation, vasopressor therapy, a temporary pacemaker lead, in addition to continuous venovenous hemodiafiltration. Two days later, the patient experienced a significant clinical improvement with normalization of the acid-base status, plasma lactate and potassium levels. On day 9, diuresis was recovered, creatinine and uremia returned to normal levels and the patient was discharged from the ICU.

    2016-02-01

    The authors illustrate a rare case of aortic arch rupture in a 60-year-old woman, occurred during a tracheostomy performed using the Griggs method. The autopsy examination showed an aortic arch rupture in an intermediate position situated in the area between the brachiocephalic artery ostium and the left common carotid artery ostium, associated to a hemorrhage filling of the adjacent connective and muscular tissue. The death was therefore determined by cardiac arrest secondary to massive hemorrhagic hypovolemic shock caused by the aortic arch rupture. The lethal iatrogenic lesion was determined by the aortic arch traction caused by the dilatation. The surgeon's incautious use of the Howard-Kelly forceps introduced in the mediastinum was therefore hypothesized.

    Designer drugs appear to be increasing in popularity because of the ease of obtaining these constituents, the lack of ability to identify the substance(s) in routine drug screening, the appeal of the drug(s) being 'safe' due to them being marketed as a 'legal high' and possibly due to stronger restrictions that are being placed on prescription drugs. As components of designer drugs are identified and regulated by the DEA, new constituents, or analogs, of these designer drugs are being manufactured to circumvent legislation. 2,5-Dimethoxy-4-chloroamphetamine (DOC) is a substituted alpha-methylated phenethylamine and acts as a selective serotonin receptor partial agonist. There is limited literature on this particular compound and no literature that attributes death to use of this drug alone. We present a case of a 37-year-old male found at home lying face down next to a book titled 'Psychedelic Chemistry' by Michael Valentine Smith and in the early stages of decomposition. The decedent was a known methamphetamine abuser. A peripheral blood sample collected at autopsy was sent to toxicology for routine analysis. Results yielded negative for the drugs of abuse classes on the enzyme-linked immunosorbent assay screen but was positive for DOC during routine GC-MS analysis. A urine sample collected at autopsy was subjected to a routine urine liquid/liquid analysis via GC-MS, and the specimen was positive for DOC. Quantification analyses showed DOC concentration levels to be 377 ng/mL in iliac blood; 3,193 ng/mL in urine; 3,143 ng/g in liver and 683 ng/g in brain. DOC was not detected in the gastric contents. Caffeine was the only other compound detected in blood and urine. Due to the lack of literature, we believe that this is the first case where death can be attributed to DOC alone.

    To explore clinical, histopathological and genetic features of a case with fatal familial insomnia (FFI) and review the related literatures. A middle-aged woman who complained of “insomnia for 9 months and psychosis for 3 months” was suspicious of FFI. The clinical features of the patient were analyzed, and the dead patient was examined by autopsy and the brain tissues were obtained for histopathological studies, and the blood samples from the patient and some of her familial members were collected for the sequencing of prion protein gene (PRNP). The main clinical features included intractable insomnia, psychiatric symptoms and abnormal night sleep behavior, unsteady gait, difficulty swallowing, sudden death, and positive family history. The pathological studies showed neuronal loss and gliosis of multiple brain tissues in the proband, predominated with thalamus; and analysis of PRNP revealed gene D178N mutation, and linkage with 129 methionine (Met) allele in the proband and a relative. FFI patients may manifest as sudden death, and may have prominent psychiatric symptoms; the corresponding gene mutation could occur in the asymptomatic carriers; the data of autopsy and brain tissue pathology is helpful for further understanding of this disease.

    A fatal pneumonia due to Legionella pneumophila was diagnosed in a young calf reared in a dairy herd located in northern Italy. Clinical symptoms consisted of watery diarrhea, hyperthermia, anorexia, and severe dyspnea. The pathological and histological findings were very similar to those observed in human legionellosis. Legionella pneumophila serogroup 1 (SG1) and SG10 were isolated from the calf’s lung, and L. pneumophila SG1 was isolated from the calf’s liver. L. pneumophila SG1 was also demonstrated in the lung tissue by immunofluorescence and immunohistochemical examinations. Nine of 10 L. pneumophila SG1 isolates belonged to the Olda subtype, and 1 belonged to the Camperdown subtype. A very low prevalence of antibodies to Legionella was detected in cows and calves reared in the same herd. Cultures of aqueous sediment of an old electric water heater which supplied hot water for the feeding of the calves yielded L. pneumophila SG1. Four of the colonies tested belonged to the Olda subtype. Ten clinical and four environmental isolates were examined for the presence of plasmids. Nine of them were also examined by pulsed-field gel electrophoresis assay, and the same patterns were found for L. pneumophila SG1 Olda strains isolated from the calf and from the electric heater. This is the first report of a documented case of a naturally occurring Legionella pneumonia in an animal. Cattle probably act as accidental hosts for legionellae, much the same as humans.

    The need to obtain dependable access to the vascular system constitutes a significant component in the treatment and management of critically ill patients. Intravenous chemotherapy administered to cancer patients over an extended period of time often results in loss of peripheral vascular access due to vein sclerosis, "exhaustion" or tissue necrosis. Medical investigators have designed and steadily upgraded a variety of devices constructed to improve venous access for long-term utilization. As with the introduction of any foreign object into the body, each of these devices has complications which may be life threatening and occasionally fatal. We present an unusual case of iatrogenic acute hydropericardium and cardiac tamponade caused by the percutaneous infusion of chemotherapeutic fluid via a right subclavian central venous implant system (Port-a-Cath). Failure to implant and monitor the device with a radiograph following placement according to manufacturer's guidelines and accepted standards of medical practice were causally related to an unusual complication, namely, perforation of the right cardiac ventricle by the catheter tip, resulting in sudden and unexpected cardiac death.

    Hair analysis for drugs has been developing and is considered a significant tool for distinguishing between recent and long-term drug abuse in forensic and clinical toxicology. Chronic consumption of drugs can gradually induce certain harmful effects on the human organism and can exacerbate some pre-existing diseases. Analysis for drugs in blood or urine in isolation does not provide sufficient information about the history of drug-use by a person and their results cannot be correlated directly with the toxic effects displayed. The chronic abuse of methamphetamine is known to be associated with cardiovascular diseases. During or after autopsy certain types of morphologic alterations are found in the hearts of stimulant addicts. The rapid increase in blood pressure after an intravenous methamphetamine dose can be risky for addicts with arteriosclerosis. However, the anamnestic data about a deceased person may not always be available to explain the pathological findings and to classify the cause of death correctly. The aim of this study was to demonstrate the value of hair analysis for drugs in the context of explaining pathological cardiovascular alterations observed during the autopsy in a case where methamphetamine consumption was involved. In this case, only methamphetamine and metabolites were detected with traces of ephedrine. Ephedrine is the precursor chemical in the illicit synthesis of methamphetamine (known in the Czech Republic as "Pervitin"). The femoral blood level of methamphetamine was 1500 ng/ml. It was documented by a witness that the 31-year-old man died within 1h after an intravenous injection of the drug. The cause of death was established as cerebral edema due to cerebellar bleeding shortly after an intravenous dose of methamphetamine. Findings of methamphetamine in the first three 2-cm hair segments (numbered from the roots) were nearly equal (132+/-9 ng/mg). In the fourth 2-cm segment, it was approximately one-half of previous values. In the

    A young female was brought into the emergency department with pulseless electrical activity (PEA) after local resection of neurofibromateous lesions. Chest ultrasonography was normal. Abdominal ultrasonography was not performed. After successful resuscitation a total body CT-scan was performed to rule out potential bleeding sources. However, haemodynamic instability reoccurred and the scan had to be aborted at the thoracoabdominal level. No thoracic abnormalities were found. Resuscitation was reinitiated and abdominal ultrasonography was performed, showing a large amount of abdominal fluid. A progressive fall in haemoglobin was noted. Emergency laparotomy was performed, revealing a large retroperitoneal haematoma. Despite ligation and packing, bleeding continued. Postoperative angiography showed active bleeding from a branch of the left internal iliac artery, which could be successfully coiled. Unfortunately, the patient died five days later due to irreversible brain damage. Revision of an MRI scan made one year earlier showed a 10 cm large retroperitoneal neurofibromatous lesion exactly at the location of the current bleeding. This case shows that patients with neurofibromatosis might develop spontaneous life-threatening bleeding from retroperitoneal located lesions. Furthermore, it points out the necessity of focused assessment with ultrasonography of the abdomen in all patients with PEA of unknown origin. PMID:25688270

    Caffeine has long been recognized as an addictive substance that causes autonomic nerve effect, and is known to increase catecholamine secretion from the adrenal glands. In recent years, the risk of ingesting toxic levels of caffeine has increased because of the easy availability of analgesics, CNS (Central Nervous System) stimulant medicine and dietary supplements at shops, health stores and through online purchases. We report the death of a young female resulting from the ingestion for suicide of an online purchased sleepiness-preventing medicine containing caffeine. The autopsy findings included pulmonary edema and congestion plus cutaneous emphysema. The stomach contents included a dark-brown viscous fluid without tablet or food residue. Toxicological examination revealed the presence of caffeine in the right heart blood (154.2 μg/mL) and stomach contents (197.5 μg/mL) (lethal blood level, >80 μg/mL). The highest caffeine content was in the bile (852.3 μg/mL). Biochemical findings showed that catecholamine concentration in the peripheral blood in the iliac vein was elevated. Immunostaining of catecholamine was weak in the adrenal medulla. We recommend highlighting the toxicity risk of ingesting substances with a high caffeine concentration, and we propose that caffeine concentrations should be included in the comprehensive routine forensic toxicological tests for all cases.

    Glyphosate herbicide is promoted by the manufacturer as having no risks to human health, with acute toxicity being very low in normal use. In Thailand, however, poisoning from glyphosate agricultural herbicides has been increasing. A case of rapid lethal intoxication from glyphosate-surfactant herbicide involved a 37-year-old woman, who deliberately ingested approximately 500 mL of concentrated Roundup formulation (41% glyphosate as the isopropylamine salt and 15% polyoxyethylene amine; Mosanto Company). The postmortem examination revealed that the stomach contained 550 mL of yellow fluid. The gastric mucosa of anterior fundus revealed hemorrhage and the small intestines had marked dilatation and thin walls. We used the high-performance liquid chromatography method for determination of serum and gastric content levels of glyphosate. The glyphosate levels of serum and gastric content were 3.05 and 59.72 mg/mL, respectively. Toxic effects of polyoxyethylene amine and Roundup were caused by their ability to erode tissues including mucous membranes and linings of the gastrointestinal and respiratory tracts. A mild degree of pulmonary congestion and edema was observed in both lungs. We proposed that the characteristic picture of microvesicular steatosis of the hepatocytes, seen predominantly in centrilobular zones of the liver, resembled drug-induced hepatic toxicity or secondary hypoxic stress.

    The authors present a case of a 45-year-old man who was found dead on the grounds of an abandoned military base. His body was discovered lying face down in a large pool of partially desiccated blood with signs of having been dragged. On-site examination revealed severe injuries to the face, neck and head, the result of having been attacked by a pack of dogs. A multi-disciplinary approach, including autopsy findings, histological examination, and bite mark analysis was performed. Photos of the injuries were taken using the specific photographic recommendations of the American Board of Forensic Odontology (ABFO). Comparisons between dental casts obtained from the dogs, and the inflicted wounds were made, resulting in positive correlations of injuries and the dental casts of three of the five dogs involved, suggesting that these dogs were probably the more active participants in the attack. This paper also highlights the ever-growing problems posed by stray dogs which tend to live under certain conditions: hunger; thirst; compromised health status; possible feelings of being threatened. At times they are also feral. This situation poses a threat to humans who come into contact with them.

    An unusual death caused by carbon monoxide poisoning after the detonation of explosives in an underground mine was investigated by the Office of the Medical Investigator of the State of New Mexico. The 50-year-old miner had 18 years of mining experience but no documented safety training. He collapsed approximately 20 minutes after entering the mine and working at the bottom of the single vertical shaft. The tight confines of the mine shaft hindered rescue personnel from reaching him, and the body was not recovered until 2 days later. The autopsy showed severe coronary artery atherosclerosis with remote and resolving myocardial microinfarcts, as well as the characteristic pink lividity of carbon monoxide poisoning, which was confirmed by laboratory analysis. Detailed investigation of the scene revealed no sources of carbon monoxide other than the explosives. The case represents an uncommon cause of death in mining that may have been avoided through the use of proper safety procedures, and illustrates the importance of recognizing the many sources of carbon monoxide.

    Background Analysis of severe maternal morbidity (maternal near misses) provides information on the quality of care. We assessed the prevalence/incidence of maternal near miss, maternal mortality and case fatality ratio through systematic review of studies on severe maternal morbidity in sub-Saharan Africa. Methods We examined studies that reported prevalence/incidence of severe maternal morbidity (maternal near misses) during pregnancy, childbirth and postpartum period between 1996 and 2010. We evaluated the quality of studies (objectives, study design, population studied, setting and context, definition of severe acute obstetric morbidity and data collection instruments). We extracted data, using a pre-defined protocol and criteria, and estimated the prevalence or incidence of maternal near miss. The case-fatality ratios for reported maternal complications were estimated. Results We identified 12 studies: six were cross-sectional, five were prospective and one was a retrospective review of medical records. There was variation in the setting: while some studies were health facility-based (at the national referral hospital, regional hospital or various district hospitals), others were community-based studies. The sample size varied from 557 women to 23,026. Different definitions and terminologies for maternal near miss included acute obstetric complications, severe life threatening obstetric complications and severe obstetric complications. The incidence/prevalence ratio and case-fatality ratio for maternal near misses ranged from 1.1%-10.1% and 3.1%-37.4% respectively. Ruptured uterus, sepsis, obstructed labor and hemorrhage were the commonest morbidities that were analyzed. The incidence/prevalence ratio of hemorrhage ranged from 0.06% to 3.05%, while the case fatality ratio for hemorrhage ranged from 2.8% to 27.3%. The prevalence/incidence ratio for sepsis ranged from 0.03% to 0.7%, while the case fatality ratio ranged from 0.0% to 72.7%. Conclusion The

    2009-01-01

    Introduction There seem to be no published data concerning the clinical impact of populations of hepatitis B virus (HBV) in the hepatic and extrahepatic compartments of HIV-infected people with severe acute hepatitis. Case presentation A 26-year-old Caucasian man presenting to our hospital with clinical symptoms suggesting acute hepatitis was found to have an acute hepatitis B profile upon admission. He developed fatal fulminant hepatitis and was found to be heavily immunocompromised due to HIV-1 infection. He had a high plasma HBV and HIV load, and analysis of the partial pre-S1/pre-S2 domain showed the presence of mixed infection with D and F genotypes. Analysis of the point mutations within this region revealed the presence of HBV strains with amino acid substitutions at the immunodominant epitopes involved in B or T cell recognition. A homogeneous population of a pre-core mutant strain harbouring the A1896G and A1899G affecting HBeAg expression was invariably found in the liver tissue, plasma and peripheral blood mononuclear cells despite active HBeAg secretion; it was the dominant strain in the liver only, and was characterised by the presence of two point mutations in the direct repeat 1 domain involved in HBV replication activity. Taken together, these mutations are indicative of a highly replicative virus capable of evading immune responses. Conclusion This case report provides clinical evidence of a possible association between the rapid spread of highly replicative escape mutants and the development of fulminant hepatitis in a heavily immunocompromised patient. Virological surveillance of severe acute hepatitis B may be important in establishing an early treatment strategy involving antiviral drugs capable of preventing liver failure, especially in individuals for whom liver transplantation is not accepted as a standard indication.

    Background Ebola virus disease (EVD) is a public health emergency of international concern. There is limited laboratory and clinical data available on patients with EVD. This is a meta-analysis to assess the utility of clinical signs, symptoms, and laboratory data in predicting mortality in EVD. Aim To assess the utility of clinical signs, symptoms, and laboratory data in predicting mortality in EVD. Method Study selection criterion: EVD articles with more than 35 EVD cases that described the clinical features were included. Data collection and extraction: Articles were searched in Medline, PubMed, Ovid journals, and CDC and WHO official websites. Statistical methods: Pooled proportions were calculated using DerSimonian Laird method (random effects model). Results Initial search identified 634 reference articles, of which 67 were selected and reviewed. Data were extracted from 10 articles (N=5,792) of EVD which met the inclusion criteria. Bleeding events (64.5% vs. 25.1%), abdominal pain (58.3% vs. 37.5%), vomiting (60.8% vs. 31.7%), diarrhea (69.9% vs. 37.8%), cough (31.6% vs. 22.3%), sore throat (47.7% vs. 19.8%), and conjunctivitis (39.3% vs. 20.3%) were more often present in pooled proportion of fatal cases as compared to EVD survivors. Conclusions Clinical features of EVD that may be associated with higher mortality include bleeding events, vomiting, diarrhea, abdominal pain, cough, sore throat, and conjunctivitis. These patients should be identified promptly, and appropriate management should be instituted immediately. PMID:26333864

    Modern global earthquake fatalities can be separated into two components: (1) fatalities from an approximately constant annual background rate that is independent of world population growth and (2) fatalities caused by earthquakes with large human death tolls, the frequency of which is dependent on world population. Earthquakes with death tolls greater than 100,000 (and 50,000) have increased with world population and obey a nonstationary Poisson distribution with rate proportional to population. We predict that the number of earthquakes with death tolls greater than 100,000 (50,000) will increase in the 21st century to 8.7±3.3 (20.5±4.3) from 4 (7) observed in the 20th century if world population reaches 10.1 billion in 2100. Combining fatalities caused by the background rate with fatalities caused by catastrophic earthquakes (>100,000 fatalities) indicates global fatalities in the 21st century will be 2.57±0.64 million if the average post-1900 death toll for catastrophic earthquakes (193,000) is assumed.

    This paper presents analyses of data from the Highway Safety Information System (HSIS) for the State of Illinois. Our analyses focuses on whether various changes in road network infrastructure and geometric design can be associated with changes in road fatalities and reported accidents. We also evaluate models that control for demographic changes. County-level time-series data is used and fixed effect negative binomial models are estimated. Results cannot confirm the hypothesis that changes in road infrastructure and geometric design have been beneficial for safety. Increases in the number of lanes appears to be associated with both increased traffic-related accidents and fatalities. Increased lane widths appears to be associated with increased fatalities. Increases in outside shoulder width appear to be associated with a decrease in accidents. Inclusion of demographic results does not significantly change these results but does capture much of the residual time trend in the models. Potentially mis-leading results are found when the time trend is not included. In this case a negative association between vertical curvature and both accidents and fatalities. No statistical association with changes in safety is found for median widths, inside shoulder widths, and horizontal and vertical curvature.

    Animal bite is a bite wound from a pet, farm or wild animal. Dog bites make up 80-85% of all reported incidents. Cats amount for about 10% of reported bites and other animals such as rodents, rabbits, horses, raccoons, bats and monkeys amount to 5-10%. Bites by mongoose are uncommon. Here, we present a case of fatal mongoose bite to an elderly woman who died as a complication of streptococcal infection at the bite site.

    For diseases with some level of associated mortality, the case fatality ratio measures the proportion of diseased individuals who die from the disease. In principle, it is straightforward to estimate this quantity from individual follow-up data that provides times from onset to death or recovery. In particular, in a competing risks context, the case fatality ratio is defined by the limiting value of the sub-distribution function, F(1)(t) = Pr(T infinity, where T denotes the time from onset to death (J = 1) or recovery (J = 2). When censoring is present, however, estimation of F(1)(infinity) is complicated by the possibility of little information regarding the right tail of F(1), requiring use of estimators of F(1)(t(*)) or F(1)(t(*))/(F(1)(t(*))+F(2)(t(*))) where t(*) is large, with F(2)(t) = Pr(T case fatality data for individuals infected with Severe Acute Respiratory Syndrome (SARS) in Hong Kong in 2003.

    Fatal and near-fatal maulings of humans by pit bulls have recently become a topic of major public concern, resulting in the passage of laws in some jurisdictions that make the owner of a pit bull criminally liable for manslaughter if his or her pet causes a human death. The authors recently investigated two cases in which children were fatally injured by pet dogs. In the first case, a 17-day-old girl suffered fatal abdominal injuries when attacked by a pregnant Siberian husky. A 2-year-old girl expired from neck wounds inflicted by a pit bull or a rottweiler or both. Because no expert would testify as to which dog caused the fatal injury, the owner of the animals was not charged under a statute which specified criminality only if a pit bull caused the fatal injury. We also examined a 12-year-old boy who attempted to pet a circus tiger; the animal grabbed his arm with its claws and bit off the arm at the shoulder. The arm could not be reattached, but the child survived. These cases and the differentiation of animal bites from other injuries will be presented.

    2013-01-01

    Background Reports of acquired immunodeficiency due to autoantibodies against interferon gamma in the adult population are increasing. The interleukin-12-dependent interferon-gamma axis is a major regulatory pathway of cell-mediated immunity and is critical for protection against a few intracellular organisms, including non-tuberculous mycobacteria and Salmonella spp. We report the first case of a fatal disseminated Mycobacterium colombiense/cytomegalovirus coinfection in an adult woman associated with the acquisition of autoantibodies against interferon-gamma. Case presentation A 49-year-old woman, born to nonconsanguineous parents in Laos, but who had lived in Canada for the past 30 years, presented with a 1-month history of weight loss, fatigue, cough, and intermittent low-grade fever. A thoracic computed tomography scan revealed an 8 × 7 cm irregular mass impacting the right superior lobar bronchus along with multiple mediastinal and hilar adenopathies. On the fourth day of admission, the patient developed fever with purulent expectorations. Treatment for a post-obstructive bacterial pneumonia was initiated while other investigations were being pursued. Almost every culture performed during the patient’s hospitalization was positive for M. colombiense. Given the late presentation of symptoms - at the age of 49 years - and the absence of significant family or personal medical history, we suspected an acquired immunodeficiency due to the presence of anti-interferon-gamma autoantibodies. This was confirmed by their detection at high levels in the plasma and a STAT1 phosphorylation assay on human monocytes. The final diagnosis was immunodeficiency secondary to the production of autoantibodies against interferon-gamma, which resulted in a post-obstructive pneumonia and disseminated infection of M. colombiense. The clinical course was complicated by the presence of a multiresistant Pseudomonas aeruginosa post-endobronchial ultrasound mediastinitis, cytomegalovirus

    Methotrexate is being used for many years in the treatment of chronic medical disorders e.g. rheumatoid arthritis since 1951. It has been associated with various systemic toxicities and complications including bone marrow suppression and lymphomas. The development of leukaemia in a patient of chronic rheumatoid arthritis is either related with the primary disease or due to the drugs which are used in the treatment like cyclophosphamide. In our present case, a 70-year-old female who was a known case of Rheumatoid Arthritis (RA) and was on methotrexate once a week orally for the past 20 years presented with complaints of loss of appetite, loss of weight and anaemia since 2 months. After thorough examination and investigation, she was diagnosed with acute myeloid leukaemia (AML-M4) with bilateral chest consolidation.

    The ingestion of extraneous substances is quite common in clinical practice; it usually befalls in the pediatric age, mostly between 6 months and 6 years. In most cases, complications do not emerge, and the prognosis is considered favorable. However, when a case of battery ingestion occurs, serious adverse events may develop. The ingestion of these components is a potential life-threatening event for children.In this article, we report the case of an 18-month-old child who died from hemorrhagic shock due to an aortoesophageal fistula caused by a 20 mm lithium button battery lodged in the esophagus.The child presented vomiting blood, and laboratory results revealed a severe anemization, which later led to death.The autopsy showed a coin battery located in the middle third of the esophagus as well as a transmural erosion of the esophageal wall with fistulization into the aortic wall. The histological examination revealed a severe necrosis of the esophageal and aortic walls in line with the junction between the aortic arch and the descending part.

    All maritime fatalities investigated by Coroners that occurred in Australia from 1992 to 1998 inclusive have been collated, coded and recorded in the Australian Boating Injury Database: Fatal Injury (ABID:FI). This article focuses on the work-related maritime fatalities recorded in the database. Over the period 1992-1998 there were 74 fatalities involving people who were working for income at the time of the incident: 46 commercial fishermen, 12 seamen involved in the transport of cargo and 16 miscellaneous workers. The fatality rate of commercial fishermen has declined substantially in Australia over recent years. The main contributing factors were: hazardous conditions; an error of judgement; unsafe work practices; and failure to wear a personal flotation device (PFD) in circumstances where, in the opinion of the Coroners, it would have saved life. Hazardous conditions were much more of a factor in fishermen deaths than in other maritime deaths. Most vessels involved had an insufficient number of PFDs for the number of crew on board. The Australian fatal injury database should be updated with the details of recent fatalities in order to further monitor safety performance, causal factors and prevention measures in the maritime industry in Australia. Attention should be focused on reducing alcohol use and increasing PFD availability and usage. In order to continue to improve safety, it is essential that a constructive dialogue is maintained with industry sources, informed by independent research and up-to-date information.

    AIMS: To describe characteristics of a series of people accidentally and deliberately killed by air powered weapons. METHODS: Five cases of fatal airgun injury were identified by forensic pathologists and histopathologists. The circumstances surrounding the case, radiological examination, and pathological findings are described. The weapon characteristics are also reported. RESULTS: Three of the victims were adult men, one was a 16 year old boy, and one an eight year old child. Four of the airguns were .22 air rifles, the other a .177 air rifle. Two committed suicide, one person shooting himself in the head, the other in the chest. In both cases the guns were fired at contact range. Three of the cases were classified as accidents: in two the pellet penetrated into the head and in one the chest. CONCLUSIONS: One person each year dies from an air powered weapon injury in the United Kingdom. In addition there is considerable morbidity from airgun injuries. Fatalities and injuries are most commonly accidents, but deliberately inflicted injuries occur. Airguns are dangerous weapons when inappropriately handled and should not be considered as toys. Children should not play with airguns unsupervised. Images PMID:9797730

    Enterovirus 71 (EV71) is a neurotropic pathogen that causes hand, foot, and mouth disease. While infection is usually self-limiting, a minority of patients infected with EV71 develop severe neurological complications. In humans, EV71 has been reported to utilize the scavenger receptor class B, member 2 (SCARB2) as a receptor for infectious cellular entry. In this study, we define the pathological features of EV71-associated disease as well as the distribution of EV71 antigen and SCARB2 in human fatal cases and a mouse model. Histopathologically, human fatal cases showed severe central nervous system (CNS) changes, mainly in the brainstems, spinal cords, and thalamus. These patient further exhibited pulmonary edema and necrotic enteritis. Immunohistochemical analysis of human fatal cases demonstrated that EV71 antigen and SCARB2 were observed mainly in neurons, microglia cells and inflammatory cells in the CNS, and epithelial cells in the intestines. However, skeletal muscle tissue was negative for EV71 antigen. In a mouse model of EV71 infection, we observed massive necrotic myositis, different degrees of viral diseases in CNS, and extensive interstitial pneumonia. In mice, EV71 exhibits strong myotropism compared to the neurotropism seen in humans. EV71 antigen was detected in the spinal cord and brainstem of mice. However, there was no clear correlation between mouse SCARB2 and EV71 antigen distribution in the mouse model, consistent with previous results that SCARB2 functions as a receptor for EV71 in humans but not mice. The EV71-induced lesions seen in the mouse model resembled the pathological changes seen in human samples. These results increase our understanding of EV71 pathogenesis and will inform further work developing a mouse model for EV71 infection.

    Single nucleotide polymorphisms (SNPs) in loci 1p13 and 9p21 have previously been found to be associated with incident coronary heart disease (CHD). This study aimed to investigate whether these SNPs show associations with fatal CHD in a population-based cohort study after adjustment for socioeconomic- and lifestyle-related CHD risk factors not commonly included in genetic association studies. Using the population-based Cohort of Norway (CONOR), a nested case-cohort study was set up and DNA from 2,953 subjects (829 cases and 2,124 non-cases) were genotyped. The association with fatal CHD was estimated for four SNPs, three from locus 1p13 and one from locus 9p21. Multivariable Cox regression was used to estimate unstratified and gender-stratified hazard ratios while adjusting for major CHD risk factors. The associations between three SNPs from locus 1p13 and non-HDL cholesterol levels were also estimated. Men homozygous for the risk alleles on rs1333049 (9p21) and rs14000 (1p13) were found to have significantly increased hazard ratios in crude and adjusted models, and the hazard ratios remained statistically significant when both genders were analyzed together. Adjustment for additional socioeconomic- and lifestyle-related CHD risk factors influenced the association estimates only slightly. No significant associations were observed between the other two SNPs in loci 1p13 (rs599839 and rs646776) and CHD mortality in either gender. Both rs599839 and rs646776 showed significant, gradual increases in non-HDL cholesterol levels with increasing number of risk alleles. This study confirms the association between 9p21 (rs1333049) and fatal CHD in a Norwegian population-based cohort. The effect was not influenced by several socioeconomic- and lifestyle-related risk factors. Our results show that 1p13 (rs14000) may also be associated with fatal CHD. SNPs at 1p13 (rs599839 and rs646776) were associated with non-HDL cholesterol levels.

    Attacks on human beings by various animals leading to varied types of injuries and even death in some cases are not uncommon. Crocodile attacks on humans have been reported from a number of countries across the globe. Deaths in such attacks are mostly due to mechanical injuries or drowning. Bites by the crocodiles often cause the limbs to be separated from the body. The present case refers to an incident of a fatal attack by a crocodile on a 35 years old female where only the mutilated head of the female was recovered. Multiple lacerated wounds over the face and scalp along with fracture of the cranial bones was detected on autopsy. Two distinct bite marks in the form of punched in holes were noted over the parietal and frontal bones. Injuries on the head with its traumatic amputation from the body were sufficient to cause death. However, the presence of other fatal injuries on the unrecovered body parts could not be ruled out.

    Takotsubo cardiomyopathy, also known as "broken heart syndrome," is a cardiac entity characterized by transient left ventricular dysfunction without obstructive atherosclerotic coronary artery disease. An episode of emotional stress is believed to act as a trigger in the development of this syndrome, which typically occurs in female patients. We report a fatal case of a previously healthy 70-year-old woman who suffered an out-of-hospital cardiac arrest and cardiac rupture during emotional distress, due to Takotsubo cardiomyopathy. Ventricular rupture with Takotsubo cardiomyopathy is rare, but our case emphasizes the importance of dealing with this serious and potentially life-threatening disease. Takotsubo cardiomyopathy should be considered as a differential diagnosis in cases of early-developing heart failure, and clinicians should subsequently use adequate diagnostic and therapeutic options.

    A liquid chromatography/tandem mass spectrometry method with solid phase extraction for the detection and the quantitation of flufenoxuron in an aliquot of blood was developed and validated. Flufenoxuron belongs to a benzoylurea insecticide and is the active ingredient of Cascade™. The analyte in postmortem specimens was extracted by solid-phase extraction with Bond Elut Certify cartridge. After the elution layer was evaporated, the residue was reconstituted with 70% methanol for LC/MS/MS analysis. Separations were carried out on a Synergi(®) 2.5u Fusion-RP 100 A column with column temperature kept at 40 °C at a flow rate of 0.4 mL/min. The mobile phase was composed of 5mM ammonium formate in 10% methanol and 5 mM ammonium formate in 90% methanol using gradient elution. A triple quadruple mass spectrometer equipped with an electrospray ionization source operated in a positive ion mode with selective reaction monitoring mode. Atrazine-d5 was used as internal standard. The assay was linear over 0.02-1.0 mg/L (r(2)=0.999). Limit of detection (LOD) and limit of quantitation (LOQ) in blood were 0.009 mg/L (S/N=3) and 0.02 mg/L (S/N=10), respectively. The accuracy and the precision were <14.9% of bias% and <8.1% of CV%, which are acceptable criteria according to toxicology laboratory guidelines. Relative recoveries with 0.02, 0.1 and 1.0mg/L (in blood) were 112.3%, 101.2% and 111.0% (n=5), respectively. The developed method was applied in forensic toxicology to determine flufenoxuron in postmortem specimens in a fatal case of flufenoxuron intoxication in a 48-year-old-man who was found dead on bed in a small room after vomiting on the floor. The postmortem heart blood, peripheral blood and gastric contents were analyzed for flufenoxuron with the result of 6.3 mg/L in heart blood, 3.2 mg/L in peripheral blood and 30.6 mg/kg in gastric contents, respectively. The concentration ratio of the heart/peripheral blood of flufenoxuron was 2.0, and the ratio of gastric

    Erlotinib is one of the most widely used tyrosine kinase inhibitor targeting human epidermal growth factor receptor. Since its introduction, it has revolutionized the treatment of advanced non-small cell lung cancer. Skin rashes and diarrhea are the most often reported side effects of erlotinib however it is also associated with interstitial pneumonitis or interstitial lung disease, which often turns out to be fatal complication of using this medicine. Though reported scarcely in the western world, the association of interstitial lung disease with epidermal growth factor receptor has attracted a lot of attention in the recent times. Various researches working with murine models of bleomycin-induced pulmonary fibrosis have found a pro and con role of the receptor in development of the interstitial lung disease. We present the case of a patient diagnosed with stage IV adenocarcinoma of the lung with metastasis to brain. He was found to be positive for the human epidermal growth factor mutation and was hence started on erlotinib. Within a few weeks of starting the medicine the patient was admitted with diarrhea. During the course of this admission he developed acute shortness of breath diagnosed as interstitial pneumonitis. The purpose of this case report is to review the literature associated with erlotinib induced interstitial pneumonitis and make the practicing oncologists aware of this rare yet fatal complication of erlotinib. Here we will also review literature, pertaining to the role of epidermal growth factor receptor in development of interstitial lung disease.

    Acute systemic toxoplasmosis was diagnosed in a 4-5-year-old, male, Domestic Short Hair cat, which had been on cyclosporine A immunomodulatory therapy for feline atopy, over an 8-month period. Cyclosporin A (CsA) has shown promising results as a immunosuppressive agent in the cat for the treatment of eosinophilic plaque and granulomas, allergic cervico-facial pruritus, feline atopy and other immune-mediated dermatoses. However, inhibition of T-lymphocyte function by CsA is believed to have predisposed this cat to the development of a newly acquired, acute Toxoplasma gondii infection, as characterized by severe hepatic and pancreatic pathology in conjunction with the heavy parasite load demonstrated on immunohistochemical (IHC) stains for T. gondii. Cats on CsA therapy appear to be at risk of developing fatal systemic toxoplasmosis.

    A review of Texas death certificates for 1975-84 identified 348 cases of fatal occupational injuries of civilian females. Homicides accounted for 53 per cent and motor vehicle-related injuries accounted for 26 per cent of the deaths. Injuries from firearms caused 70 per cent of the homicides. One hundred thirty-three deaths occurred to women employed in the retail trade industry; of these, 77 per cent resulted from homicide. Women workers in gasoline service stations, food-bakery-and-dairy stores, and eating-and-drinking places had especially high risks of homicide. Texas female heavy-truck drivers had the highest fatal-injury rate, with motor-vehicle-related injuries causing 89 per cent of their deaths. These results indicate that effective strategies to prevent fatal occupational injuries of Texas women will need to address the problems of workplace violence and the hazards posed by motor vehicles.

    Introduction: Dengue and meningococcal disease are caused by two different agents: a flavivirus and a Gram-negative bacterium, respectively. The first symptoms of both diseases can be indistinct and a rapid and accurate diagnosis is crucial, considering that both diseases are associated with high morbidity and mortality, representing a major public-health problem in Brazil. Case presentation: We report a fatal case of co-infection of dengue virus (DENV) and Neisseria meningitidis in a 54-year-old patient. The serum tested positive for DENV NS1 antigen, and N. meningitidis serogroup C was detected by nspA-PCR. Following the initial positive result for DENV infection, rRT-PCRwas performed and DENV-4 was confirmed. Conclusion: Our report highlights the importance of accurate differential diagnosis during periods of high circulation of DENV, in order to provide adequate management and an improved outcome.

    Two cases of fatalities are reported of which the recreational use of Mitragyna speciosa ("kratom") could be confirmed. One of these cases presents with one of the highest postmortem mitragynine concentrations published to date. Our results show that even extremely high mitragynine blood concentrations following the consumption of kratom do not necessarily have to be the direct cause of death in such fatalities as a result of an acute overdose. The two cases are compared with regard to the differences in mitragynine concentrations detected and the role of mitragynine in the death of the subjects. Irrespective of the big differences in mitragynine concentrations in the postmortem blood samples, mitragynine was not the primary cause of death in either of the two cases reported here. Additionally, by rough estimation, a significant difference in ratio of mitragynine to its diastereomers in the blood and urine samples between the two cases could be seen.

    Campylobacter jejuni (C. jejuni) bacteremia is difficult to diagnose in individuals with hematological disorders undergoing chemotherapy. The cause can be attributed to the rarity of this infection, to the variable clinical presentation, and to the partial overlapping symptoms underlying the disease. Here, we report a case of a fatal sepsis caused by C. jejuni in a 76-year-old Caucasian man with non-Hodgkin's lymphoma. After chemotherapeutic treatment, the patient experienced fever associated with severe neutropenia and thrombocytopenia without hemodynamic instability, abdominal pain, and diarrhea. The slow growth of C. jejuni in the blood culture systems and the difficulty in identifying it with conventional biochemical phenotyping methods contributed to the delay of administering a targeted antimicrobial treatment, leading to a fatal outcome. Early recognition and timely intervention are critical for the successful management of C. jejuni infection. Symptoms may be difficult to recognize in immunocompromised patients undergoing chemotherapy. Thus, it is important to increase physician awareness regarding the clinical manifestations of C. jejuni to improve therapeutic efficacy. Moreover, the use of more aggressive empirical antimicrobial treatments with aminoglycosides and/or carbapenems should be considered in immunosuppressed patients, in comparison to those currently indicated in the guidelines for cancer-related infections supporting the use of cephalosporins as monotherapy.

    This case study reports on changes in emotions before and during an unexpected heart rate in a young, apparently healthy male with a life-long history of exercise in the absence of family history of heart problems. He completed the Brunel Mood Scale (Terry et al. , 2003) to assess emotions before, during, and after the heart attack, and also describing his thoughts during these periods. Results indicate he experienced unpleasant emotions in the build up to the heart attack, feelings he attributed at the time to frustration to achieve fitness goals. He maintained an exercise regime prior to having a heart attack, a finding consistent with previous research suggesting that early diagnosis, although vital for survival, is not likely to be identified among seemingly healthy individuals. During the heart attack, he experienced a rapid emotional change characterised by a rapid increase in anger coupled with thoughts of needing to survive. The intensity of emotions and regulation strategies employed before and during the heart attack provide insight this experience, and we suggest future research should investigate emotional change during adverse conditions. Key pointsThe present case study details emotions experienced and attempts to regulate these emotions before, during and post a heart attack. Unpleasant emotions experienced before the heart were attributed to lack of progress toward fitness goals, a perception that is plausible as he was a regular exerciser.Early identification of heart attack is critical as "Time is Muscle" (Whyte et al., 2009) and therefore even people perceived to be at low risk should consider the possibility of such an eventuality, and seek medical treatment early in the process.

    Motor vehicle crashes are the leading cause of work-related fatality in the U.S. as well as in the oil and gas extraction industry. This study describes the characteristics of motor vehicle-related fatalities in the oil and gas extraction industry using data from the U.S. Bureau of Labor Statistics' Census of Fatal Occupational Injuries. It compares the risk of dying in a motor vehicle crash in this industry to other major industries and among different types and sizes of oil and gas extraction companies. There were 202 oil and gas extraction workers who died in a work-related motor vehicle crash from 2003 to 2009. The motor vehicle fatality rate for workers in this industry was 8.5 times that of all private wage and salary workers (7.6 vs. 0.9, p<.0001). Workers from small oil and gas establishments (<20 workers) and workers from well-servicing companies were at greatest risk of dying in a motor vehicle crash. Pick-up trucks were the most frequent type of vehicle occupied by the fatally injured worker (n=104, 51.5%). Safety belt non-use was identified in 38.1% (n=77) of the cases. Increased focus on motor vehicle safety in this industry is needed, in particular among small establishments. Extraction workers who drive light duty vehicles need to be a specific focus.

    Dengue disease is an acute viral illness caused by dengue virus (DENV) that can progress to hemorrhagic stages leading to about 20000 deaths every year worldwide. Despite many clinical investigations regarding dengue, the immunopathogenic process by which infected patients evolve to the severe forms is not fully understood. Apart from differences in virulence and the antibody cross reactivity that can potentially augment virus replication, imbalanced cellular immunity is also seen as a major concern in the establishment of severe dengue. In this context, the investigation of cellular immunity and its products in dengue fatal cases may provide valuable data to help revealing dengue immunopathogenesis. Here, based in four dengue fatal cases infected by the serotype 3 in Brazil, different peripheral organs (livers, lungs and kidneys) were studied to evaluate the presence of cell infiltrates and the patterns of local cytokine response. The overall scenario of the studied cases revealed a considerable systemic involvement of infection with mononuclear cells targeted to all of the evaluated organs, as measured by immunohistochemistry (IHC). Quantification of cytokine-expressing cells in peripheral tissues was also performed to characterize the ongoing inflammatory process by the severe stage of the disease. Increased levels of IFN-γ- and TNF-α-expressing cells in liver, lung and kidney samples of post-mortem subjects evidenced a strong pro-inflammatory induction in these tissues. The presence of increased RANTES-producing cell numbers in all analyzed organs suggested a possible link between the clinical status and altered vascular permeability. Co-staining of DENV RNA and IFN-γ or TNF-α using in situ hibridization and IHC confirmed the virus-specific trigger of the pro-inflammatory response. Taken together, this work provided additional evidences that corroborated with the traditional theories regarding the “cytokine storm” and the occurrence of uneven cellular

    In 2009, a new influenza A (H1N1) virus affected many persons around the world. There is an urgent need for finding biomarkers to distinguish between influenza A (H1N1)pdm09 and seasonal influenza virus. We investigated these possible biomarkers in the lung of fatal cases of confirmed influenza A (H1N1)pdm09. Cytokines (inflammatory and anti-inflammatory) and cellular markers (macrophages and lymphocytes subpopulation markers) were analyzed in lung tissue from both influenza A (H1N1)pdm09 and seasonal influenza virus. High levels of IL-17, IFN-γ, and TNF-α positive cells were identical in lung tissue from the influenza A (H1N1)pdm09 and seasonal cases when compared with healthy lung tissue (P < 0.05). Increased IL-4+ cells, and CD4+ and CD14+ cells were also found in high levels in both influenza A (H1N1)pdm09 and seasonal influenza virus (P < 0.05). Low levels of CD206+ cells (marker of alternatively activated macrophages marker in lung) were found in influenza A (H1N1)pdm09 when compared with seasonal influenza virus (P < 0.05), and the ratio of CD206/CD14+ cells was 2.5-fold higher in seasonal and noninfluenza group compared with influenza A (H1N1)pdm09 (P < 0.05). In conclusion, CD206+ cells differentiate between influenza A (H1N1)pdm09 and seasonal influenza virus in lung tissue of fatal cases. PMID:25614715

    A rare case of a big cat fatal attack is presented. A male leopard that had escaped from its unlocked cage attacked a 26-year-old male zoo worker. The man sustained penetrating injuries to the neck with consequent external bleeding. The man died while being transported to the hospital as a result of the injuries sustained. The wounds discovered on the victim's body corresponded with the known methods of leopard attacks and with findings on the carcasses of animals killed by leopards in the wild. The conclusion of the medicolegal investigation was that the underlying cause of death was a bite wound to the neck which lacerated the left internal jugular vein, the two main branches of the left external carotid artery, and the cervical spine. The cause of death was massive external bleeding. Special attention is paid to the general pattern of injuries sustained from big cat attacks.

    Fatal occupational injuries were studied using data from medical examiners' reports in North Carolina for the years 1977-1991. Cases were defined as deaths due to accidents or homicide at the workplace, and populations at risk were estimated from the 1980 and 1990 US Censuses. Mortality rate ratios and proportionate mortality ratios were used as measures of association, and the population attributable risk percentage was used as an indicator of the burden of injury. Standard weights for direct age-adjustment of rates were obtained from the total state workforce. There were 2,524 eligible deaths-83 percent from unintentional traumatic injuries, 14 percent from homicide, and the remainder from other causes. This report focuses on unintentional trauma deaths, which were strongly associated with the wood production, fishing, and transportation industries. Elderly, African-American, and self-employed workers had higher fatality rates than members of other groups. Among male workers, motor vehicle crashes were the principal cause of death on the job, followed by falling objects, machinery, and falls. The industries contributing the largest proportions of these deaths were construction, trucking, agriculture, and logging (population attributable risk percentages were 16.8%, 8.8%, 7.9%, and 6.9%, respectively). The fatality patterns of female workers were different: Numbers of deaths from homicide and unintentional trauma were equal, and 27% of the latter deaths occurred in one catastrophic fire. Decentralized and rural industries were the most hazardous, but many deaths were outside the current jurisdiction of occupational safety and health agencies. These patterns suggest that greater scrutiny of such industries, through both research and intervention, is warranted.

    Flaviviruses are significant causes of disease worldwide and can be classified serologically into several antigenic complexes. The purpose of the present study was to evaluate the effectiveness of a generic RT-nested-PCR for detection of flavivirus during a dengue outbreak in Brazil in 2008. A total of 105 serum samples were collected from patients with fatal outcome and examined by generic RT-PCR, conventional RT-PCR, and IgM serology. The generic RT-PCR confirmed 19 of 105 (18%) cases. Conventional RT-PCR performed on 105 serum samples detected 45 (42.8%) dengue virus infections. The IgM serology confirmed 44 of 102 (43.1%) cases. The infecting serotype was identified by generic RT-PCR in 19 cases (18 DENV-2 and 1 DENV-3) and by conventional RT-PCR in 45 cases (40 DENV-2 and 5 DENV-3). In addition, we analyzed the performance of the generic and conventional RT-PCRs and IgM serology on serum samples stratified by the day of onset of symptoms. Our results indicate that different methods should be included in flavivirus surveillance programs, including virological and serological approaches.

    Vascular Ehlers-Danlos Syndrome (previously Ehlers-Danlos IV) is a rare autosomal dominant collagen vascular disorder caused by a 2q31 COL3A1 gene mutation encoding pro-alpha1 chain of type III collagen (in contrast to classic Ehlers-Danlos, caused by a COL5A1 mutation). The vascular type accounts for less than 4% of all Ehlers-Danlos cases and usually has a poor prognosis due to life threatening vascular ruptures and difficult, frequently unsuccessful surgical and vascular interventions. In 70% of cases, vascular rupture or dissection, gastrointestinal perforation, or organ rupture is a presenting sign. We present a case of genetically proven vascular Ehlers-Danlos with fatal recurrent retroperitoneal hemorrhages secondary to a ruptured right common iliac artery dissection in a 30-year-old male. This case highlights the need to suspect collagen vascular disorders when a young adult presents with unexplained retroperitoneal hemorrhage, even without family history of such diseases.

    In 2003, the occurrence and location of horses with clinical signs of West Nile virus infection were identified in the southern portion of Saskatchewan with the help of veterinarians, owners, and the regional laboratory. A total of 133 clinical cases were reported between July 30 and September 19, 2003; however, postseason surveillance suggests that the number of cases was underestimated. The case fatality rate was 43.8% (95% CI 35.2, 52.4). Factors associated with fatality in clinical cases included sex, week of onset of clinical signs, and coat color. Reported clinical cases clustered within regional health authority districts, suggesting regional differences in geographic factors, potentially including climate and mosquito control, that could contribute to the risk of disease. However, most of the variation in the risk of fatality in clinical cases is explained at the individual level rather than the Regional Health Authority level, which suggests the outcome of clinical disease is primarily determined by characteristics of, or management factors affecting, the individual horse.

    Methoxetamine (MXE) is a new synthetic drug of abuse structurally related to ketamine and phencyclidine. A case of a 29-year-old male with acute toxicity related to the analytically confirmed use of MXE is reported. The man was found dead at his residence. Biological material was analyzed using liquid chromatography-tandem mass spectrometry. The concentration of MXE in urine of the deceased was 85 μg/mL. Despite the vial containing the blood sample being destroyed during transportation and the blood leaking out into the cardboard packaging, the blood level of MXE was estimated. After determination of the cardboard grammage (approx. 400 g/m(3) ) and the mean mass of the blood obtained after drying (0.1785 ± 0.0173 g per 1 mL), the estimated blood concentration of MXE was found to be 5.8 μg/mL. The high concentration of MXE in blood and urine and the circumstances of the case indicate an unintentional, fatal intoxication with this substance.

    Abstract: Background: The global incidence of fatal head injuries as the result of assault is greater than the number of non-fatal cases. The important factors that determine the outcome in terms of survival of such head injury cases include the type of weapon used, type and site of skull fracture, intra cranial haemorrhage and the brain injury. The present study aims to highlight the role of skull fractures as an indirect indicator of force of impact and the intra cranial haemorrhage by a comparative study of assault victims with fatal and nonfatal head injuries. Methods: 91 head injury cases resulting from assault were studied in the Department of Forensic Medicine, IMS, BHU Varanasi over a period of 2 years from which 18 patients survived and 73 cases had a lethal outcome. Details of the fatal cases were obtained from the police inquest and an autopsy while examination of the surviving patients was done after obtaining an informed consent. The data so obtained were analyzed and presented in the study. Results: Assault with firearms often led to fatality whereas with assault involving blunt weapons the survival rate was higher. Multiple cranial bones were involved in 69.3% cases while comminuted fracture of the skull was common among the fatal cases. Fracture of the base of the skull was noted only in the fatal cases and a combination of subdural and subarachnoid haemorrhage was found in the majority of the fatal cases. Conclusions: The present study shows skull fractures to be an important indicator of severity of trauma in attacks to the head. Multiple bone fracture, comminuted fracture and base fractures may be considered as high risk factors in attempted homicide cases. PMID:21483205

    We report a fatal case of streptococcal and meningococcal meningitis in a previously healthy 2-year-old child, a simultaneous co-infection of both pathogens that is poorly reported in the reviewed literature. The lack of a clinical diagnosis in addition to the medico-legal aspects arising from possible professional liability for the emergency service doctor who had failed to recognize the child's symptoms led to a forensic autopsy within 48 h after the death. After external and internal examination, Waterhouse-Friderichsen Syndrome (WFS) was suspected. Consequently, cerebrospinal fluid, whole blood, nasal and pharyngeal swab and pleural liquid samples were selected and collected for microbiological studies. All tested samples resulted Neisseria meningitidis DNA and Streptococcus pneumoniae DNA positive. The NM genotyping Real-Time PCR resulted positive for NM serotype C. Microscopic histological study confirmed these findings. We underline that when a patient presents fever and petechiae (50-60% of patients), WFS must be considered, even when the patient has a non-toxic appearance. Due to its rapid progression and often devastating consequences, therapy should be started as soon as WFS is suspected. Emphasis should also be placed on the importance of public education programs and on broadening protection against meningitis through new vaccines. In such cases, from a forensic point of view, there is a strong need for a robust, multidisciplinary approach in order to reach the correct post-mortem diagnosis.

    Background. West Nile virus (WNV) infection in humans can result in severe, acute encephalitis typically involving subcortical gray matter brain regions. West Nile virus replication within specific human brain regions from a human case of acute encephalitis has not been studied. Methods. We describe a fatal case of WNV encephalitis in which we obtained tissue from specific brain regions at autopsy to evaluate viral-host interactions using next-generation sequencing and immunohistochemistry analysis. Results. We found that WNV populations in the injured subcortical brain regions exhibited increased amino acid variation and increased expression of specific interferon genes compared with cortical tissues despite similar viral burden. Conclusions. These observational, patient-based data suggest that neuronal injury and the strength of viral selection pressure may be associated with the level of the innate immune responses. Further studies in human and animal models evaluating the role of innate immune responses on injury patterns and viral selection pressure are needed. PMID:26730392

    Non-HIV immunocompromised patients may develop immune reconstitution inflammatory syndrome (IRIS) as an abnormal response to invading microorganisms, such as Mycobacterium tuberculosis (MTB). IRIS consists in a sudden change in the dominant T-helper responses to inflammation, which is not balanced by anti-inflammatory response, playing a critical role in microbial pathogenesis. A patient with restoration of host immunity during anti-tuberculosis treatment can become gravely ill with a paradoxical severe form of tuberculosis (TB) disease named TB immune reconstitution disease (IRD).The diagnosis of acute cryptic miliary TB is difficult and requires an accurate histopathology. We report a fatal association between a generalized lymphadenitis tuberculosis and IRD in a 34-year-old male patient, non-smoker, non-HIV immunocompromised, but with a previously co-morbid diabetes mellitus (DM) type I. The purpose of this report is to describe an unusual and rare case of a progressive extrapulmonary TB disease to a liver involvement, mimicking a hepatotoxicity secondary to anti-tuberculosis therapy. The diagnosis of disseminated miliary TB with cryptic pulmonary was confirmed later after performing necropsy. Formalin-fixed paraffin-embedded pulmonary and extrapulmonary miliary foci were processed for histology and stained with Hematoxylin and Eosin. This rare entity of cryptic miliary involvement of the lungs is described more in elderly than in young individuals. In the reported case, IRD induced a paradoxical progressive dissemination of TB lesions leading to death in a patient with an apparent uncomplicated form of lymphadenitis TB.

    This study evaluated occupational deaths resulting from fall injuries among Hispanic construction workers using data from the Census of Fatal Occupational Injuries and the Current Population Survey. The demographics and characteristics of fatal falls among Hispanic workers were examined and compared with that of their white, non-Hispanic counterparts. The results show that fatal injuries among Hispanic construction workers were more likely to be caused by a fall than their white, non-Hispanic counterparts (OR=1.48, 95% CI: 1.05-2.10) after controlling for possible confounders. The rate of fatal falls for foreign-born Hispanic construction workers was 5.5 per 100,000 FTE, which is significantly higher than 4.1 per 100,000 FTE for Hispanic workers who were born in the U.S. (OR=1.36, 95% CI: 1.08-1.67). The disparities in fatal injuries from falls were found in age groups, job tenure, occupations, and types of construction projects. This study also found that about every two of three fatal falls in construction occurred in establishments with 10 or fewer employees. More prevention, intervention, and training measures must be applied to Hispanic workers, especially those who are new immigrants. OSHA enforcements should target small construction establishments in order to lower overall fatality rates, costs, and unnecessary losses of life.

    We report the first case of aspergillus mycotic aneurysm as a sequel to concomitant prostatic and renal aspergillosis. The patient had undergone left nephrectomy and transurethral resection of prostate for aspergillus infection one year ago. He again presented with LUTS and backache and clinical examination showed visible pulsations in the epigastrium. CT-scan abdomen showed a pseudoaneurysm of the abdominal aorta. The aneurysm was repaired in situ with homografting and omental wrap. However, the patient succumbed to septicemia on the tenth postoperative day. Adjunctive surgery is usually essential as medical management alone has been unsatisfactory. It is imperative that these cases should be followed closely to detect the disease recurrence and complications at the earliest.

    Nosocomial catheter-related and Arteriovenous fistula (AV)-related infections are significant concern in patients undergoing haemodialysis. These infections are associated with multiple complications as well as mortality and demands immediate and appropriate management. While coagulase-negative staphylococci, S.aureus, and Escherichia coli are the most common causes of catheter-related infections in haemodialysis patients, such infections caused by Pseudomonas aeruginosa are relatively rare. Here, we present an unusual case of 36-year-old male patient with chronic renal failure, who developed endocarditis and sepsis from Pseudomonas aeruginosa infection of the left hand arteriovenous fistula. The bacteraemia in the present case caused multiple complications including dry gangrene of bilateral lower limbs, stroke, endophthalmitis, left brachial artery thrombosis and vegetations on the interventricular septum and aortic wall. Despite antibiotic treatment, the patient suffered a cardiac arrest and could not be revived. PMID:27630891

    Introduction. Osteoarthritis, a degenerative joint disease, is a key cause of disability around the world and an ever-growing public health concern. Intra-articular hyaluronic acid viscosupplementation is used as a conservative option for osteoarthritis knee pain relief (McArthur et al., 2012; Hootman and Helmick, 2006; Huang el al., 2011). In general, the literature has shown an excellent safety profile for this treatment modality (McArthur et al., 2012; Clegg et al., 2013; Hammesfahr et al., 2003; Neustadt et al., 2005; Cohen et al., 2008; Neustadt, 2003; Jüni et al., 2007; Peterson and Hodler, 2011). Case Presentation. In this report, we describe a case of a woman who had received multiple sodium hyaluronate injections and developed severe necrotizing fasciitis near the injection site. Conclusion. We recommend that clear guidelines for clean technique be put in place for use with sodium hyaluronate injections and consideration of full sterile technique in immunosuppressed patients.

    In patients with sickle cell disease, hyperhemolysis is a rare but life-threatening complication of transfusion. In this case report, we describe a 61 year-old woman with hemoglobin sickle cell (SC) disease and history of alloimmunization who developed hyperhemolysis associated with a transfusion. She was found to have a warm and a clinically-significant cold autoantibody. Severe anemia (Hb 2.7 g/dL) with reticulocytopenia and thrombocytopenia prompted a bone marrow biopsy, which demonstrated extensive bone marrow necrosis. Despite treatment, the bone marrow failure did not improve and the patient died on hospital day 38. This case illustrates the potential risks of transfusion in a patient with sickle cell disease, especially one with previous hemolytic reactions. While uncommon, hyperhemolysis can cause death, in this case by extensive bone marrow necrosis. In patients with sickle cell disease, judicious use of red cell transfusions with phenotypically-matched units can diminish, but never completely abrogate, the risks associated with transfusion.

    Cases of mushroom poisoning in Thailand have increased annually. During 2008 to 2014, the cases reported to the National Institute of Health included 57 deaths; at least 15 died after ingestion of amanitas, the most common lethal wild mushrooms inhabited. Hence, the aims of this study were to identify mushroom samples from nine clinically reported cases during the 7-year study period based on nuclear ITS sequence data and diagnose lethal peptide toxins using a reversed phase LC-MS method. Nucleotide similarity was identified using BLAST search of the NCBI database and the Barcode of Life Database (BOLD). Clade characterization was performed by maximum likelihood and Bayesian phylogenetic approaches. Based on BLAST and BOLD reference databases our results yielded high nucleotide similarities of poisonous mushroom samples to A. exitialis and A. fuliginea. Detailed phylogenetic analyses showed that all mushroom samples fall into their current classification. Detection of the peptide toxins revealed the presence of amatoxins and phallotoxins in A. exitialis and A. fuliginea. In addition, toxic α-amanitin was identified in a new provisional species, Amanita sp.1, with the highest toxin quantity. Molecular identification confirmed that the mushrooms ingested by the patients were members of the lethal amanitas in the sections Amanita and Phalloideae. In Thailand, the presence of A. exitialis was reported here for the first time and all three poisonous mushroom species provided new and informative data for clinical studies.

    2008-01-01

    The clarification of deaths from electric current can be difficult when electric skin marks are missing or overlooked. In the following, the fatal electric accident of a 21-year-old man in prison is reported with a scene which primarily seemed to be inconspicuous. The autopsy disclosed typical electric marks in the skin of the left thumb and the corresponding part of the left index finger. A second inspection of the jail room, which was large enough for three men, but occupied by the deceased alone, led to the finding of widely spread utensils (two forks with signs of corrosion and deformation of the prongs, radio cable with socket, water container) for the self-construction of a kind of "immersion heater" for the heating of water. The man must have suffered electrocution when touching the prongs of the forks. Death supposedly occurred due to disturbances of the cardiac rhythm after a longer interval of maintained ability to act. The case again proves the difficulties in the detection and examination of possible electric deaths in which unusual sources of electricity must be considered.

  7. [Fatal rat bites].

    1999-04-15

    We present a rare case of infant death due to blood loss resulting from multiple rat bites. Domestic dogs and cats cause most animal bites. Bites of a house rat usually cause bacterial infection, successfully treated with antibiotics. There is little information about death due to house rat bites. Since the wounds they cause tend to occur post-mortem, they are usually wedged, clean and without subcutaneous bleeding. An 11-week-old, malnourished infant girl was bitten to death while sleeping in her mother's bed in a rat-infested home. The infant's clothing was covered with blood, parts of her face were missing and marks of gnawing were present on her neck and extremities. There was subcutaneous bleeding around the wounds indicating that they were inflicted while the child was alive. Autopsy findings revealed profound blood loss. We conclude that a combination of low socio-economic status, severe failure to thrive, and poor hygiene in a rat-infested environment contributed to the fatal outcome in this attack.

    2015-02-01

    A novel application of age-period-cohort methods are used to explain changes in vehicle based crash rates in New South Wales, Australia over the period 2003-2010. Models are developed using vehicle age, crash period and vehicle cohort to explain changes in the rate of single vehicle driver fatalities and injuries in vehicles less than 13 years of age. Large declines in risk are associated with vehicle cohorts built after about 1996. The decline in risk appears to have accelerated to 12 percent per vehicle cohort year for cohorts since 2004. Within each cohort, the risk of crashing appears to be a minimum at two years of age and increases as the vehicle ages beyond this. Period effects (i.e., other road safety measures) between 2003 and 2010 appear to have contributed to declines of up to about two percent per annum to the driver-fatality single vehicle crash rate, and possibly only negligible improvements to the driver-injury single vehicle crash rate. Vehicle improvements appear to have been responsible for a decline in per-vehicle crash risk of at least three percent per calendar year for both severity levels over the same period. Given the decline in risk associated with more recent vehicle cohorts and the dynamics of fleet turnover, continued declines in per-vehicle crash risk over coming years are almost certain.

    Blood samples of two cases were analyzed preliminarily by a classical spectrophotometric method (VIS) and by an automated headspace gas chromatographic method with nitrogen-phosphorus detector (HS-GC/NPD). In the former, hydrogen cyanide (HCN) was quantitatively determined by measuring the absorbance of chromophores forming as a result of interaction with chloramine T. In the automated HS-GC/NPD method, blood was placed in a headspace vial, internal standard (acetonitrile) and acetic acid were then added. This resulted in cyanide being liberated as HCN. The spectrophotometric (VIS) and HS-GC/NPD methods were validated on postmortem blood samples fortified with potassium cyanide in the ranges 0.5-10 and 0.05-5 mug/mL, respectively. Detection limits were 0.2 mug/mL for VIS and 0.05 mug/mL for HS-GC/NPD. This work shows that results obtained by means of the two procedures were insignificantly different and that they compared favorably. They are suitable for rapid diagnosis of cyanide in postmortem cases.

    Inhalatomania with volatile organic compounds is a still present phenomenon among Polish young adolescents. Conscious, voluntary exposition on such substances may result in serious health consequences, including sudden death in the course of acute intoxication. In this paper, atypical case of death of 16-year-old teenager as a result of complications of physically forced inhalation of gas for lighters is presented. According to testimonies of witnesses, the container was placed in the mouth of victim and the gas was introduced directly to his throat. Autopsy revealed small damage of tooth with corresponding bruising of lower lip; brain and lung oedma; single bruisings in the upper respiratory tract and subpleural. Chemical-toxicological analysis of blood, brain and lung samples taken during autopsy revealed in all of them the presence of n-butan--a component of gas for lighters (the greatest in brain and lung tissues). Additionally, in blood the presence of carboxyhemoglobin (COHb) in concentration 7% was confirmed. Based on the results of analyses, acute intoxication with n-butan was estimated as a cause of death; however the key role played the information obtained during the investigation. This case shows, that deaths resulting from gas for lighters inhalation may be a consequence of forced exposition--against victim's will. So medical staff should always check, if on the body of patient there are any signs of physical constraint (the presence of bruisings in the area of viscerocranium and oral cavity, teeth damages, etc.).

    PubMed Central

    2013-01-01

    In spite of yearly vaccination, outbreaks of canine infectious respiratory disease are periodically seen amongst domestic dogs. These infections compromise host defense mechanisms, and, when combined with other stressful events, allow opportunistic pathogens like Streptococcus equi subsp. zooepidemicus to create serious disease. Early recognition and treatment are tremendously important for a successful outcome in these cases. A polyvalent vaccine was given to 22 racing dogs three days after a competition, followed by two days of rest, and then the dogs were returned to regular training. Coughing was noticed among the dogs four days after immunisation. Three days after this outbreak one of the dogs was unusually silent and was found dead the next morning. Simultaneously two other dogs developed haemorrhagic expectorate, depression and dyspnea and were brought in to the veterinary hospital. Streptococcus equi subsp. zooepidemicus was isolated in pure culture from all three cases. They were treated and rehabilitated successfully, and won a sledge race three months later. This paper discusses the necropsy results, treatment regime, rehabilitation and the chronology of vaccination, stressful events and disease. PMID:24020788

    Objectives To identify potentially fatal injury patterns in explosive blast fatalities in order to focus research and mitigation strategies, to further improve survival rates from blast trauma. Design Retrospective cohort study. Participants UK military personnel killed by improvised explosive device (IED) blasts in Afghanistan, November 2007–August 2010. Setting UK military deployment, through NATO, in support of the International Security Assistance Force (ISAF) mission in Afghanistan. Data sources UK military postmortem CT records, UK Joint Theatre Trauma Registry and associated incident data. Main outcome measures Potentially fatal injuries attributable to IEDs. Results We identified 121 cases, 42 mounted (in-vehicle) and 79 dismounted (on foot), at a point of wounding. There were 354 potentially fatal injuries in total. Leading causes of death were traumatic brain injury (50%, 62/124 fatal injuries), followed by intracavity haemorrhage (20.2%, 25/124) in the mounted group, and extremity haemorrhage (42.6%, 98/230 fatal injuries), junctional haemorrhage (22.2%, 51/230 fatal injuries) and traumatic brain injury (18.7%, 43/230 fatal injuries) in the dismounted group. Conclusions Head trauma severity in both mounted and dismounted IED fatalities indicated prevention and mitigation as the most effective strategies to decrease resultant mortality. Two-thirds of dismounted fatalities had haemorrhage implicated as a cause of death that may have been anatomically amenable to prehospital intervention. One-fifth of the mounted fatalities had haemorrhagic trauma which currently could only be addressed surgically. Maintaining the drive to improve all haemostatic techniques for blast casualties, from point of wounding to definitive surgical proximal vascular control, alongside the development and application of novel haemostatic interventions could yield a significant survival benefit. Prospective studies in this field are indicated. PMID:23906957

    The intense economic growth experienced by Brazil in recent decades and its consequent explosive motorization process have evidenced an undesirable impact: the increasing and unbroken trend in traffic fatality numbers. In order to contribute to road safety diagnosis on a national level, this study presents a research into two main indicators available in Brazil: mortality rate (represented by fatalities per capita) and fatality rate (represented by two sub-indicators, i.e., fatalities per vehicle and fatalities per vehicle kilometer traveled). These indicators were aggregated into a composite indicator or index through a multiple layer data envelopment analysis (DEA) composite indicator model, which looks for the optimum combination of indicators' weights for each decision-making unit, in this case 27 Brazilian states. The index score represents the road safety performance, based on which a ranking of states can be made. Since such a model has never been applied for road safety evaluation in Brazil, its parameters were calibrated based on the experience of more consolidated European Union research in ranking its member countries using DEA techniques. Secondly, cluster analysis was conducted aiming to provide more realistic performance comparisons and, finally, the sensitivity of the results was measured through a bootstrapping method application. It can be concluded that by combining fatality indicators, defining clusters and applying bootstrapping procedures a trustworthy ranking can be created, which is valuable for nationwide road safety planning.

    A 38-year-old male farm worker with relapsing acute lymphoblastic leukemia spontaneously developed an ulcerating ulcer on his anterior thigh which was surrounded by a non-tender area of erythema. Bacillus cereus was isolated from the ulcer and blood, and the patient received intravenous penicillin and vancomycin for one week. When sensitivity studies were returned he was treated with gatifloxacin orally. After two weeks of combined antimicrobial therapy and negative blood cultures, the patient received combination chemotherapy with vincristine, prednisone, doxorubicin and cyclophosphamide. He was hospitalized a day after completing chemotherapy with neutropenic sepsis due to B. cereus. He received similar antimicrobial therapy as previously, but died three days later. At autopsy, the patient was found to have acute mitral valve endocarditis and bilateral brain abscesses. This was the first case of B. cereus endocarditis reported in a patient with acute lymphoblastic leukemia.

    A previously healthy 23-year-old woman was admitted to hospital with abdominal pain at 39 weeks 0 days of pregnancy. The patient suffered sudden cardiopulmonary arrest during the observation and unfortunately died. An autopsy was performed to determine the cause of death. Opening of the peritoneal cavity revealed 2220 mL of blood and a subcapsular hematoma weighing 1060 g on the anterior surface of the right hepatic lobe. A lesion of c. 1 cm in diameter was noted at the center of the front surface of the right hepatic lobe, which was shown on histological examination to be a focal nodular hyperplasia-like lesion. The cause of death was found to be hypovolemic shock caused by bleeding of the rupture of the hepatocellular hyperplastic nodule. Although some previous case reports describe hemorrhage from such lesions, forensic pathologists should be aware that they can lead to severe bleeding and sometimes death.

    A lethal case of Brazilian spotted fever (BSF) is presented. Clinical features were initially of gastrointestinal involvement and evolved with progression to septic shock, meningoencephalitis and death on the 6th day of illness. Indirect immunofluorescence assay (IFA) for spotted fever group rickettsia (SFGR) was non-reactive. Diagnosis was confirmed by the polymerase chain reaction (PCR) and the nucleotide sequencing of a fragment of the ompA gene showed 100% homology to Rickettsia rickettsii. BSF has not been reported in the city of Rio de Janeiro in the last three decades, and the present description should alert the clinicians to its presence in urban Rio de Janeiro, and to the differential diagnosis with dengue fever, gastroenteritis, leptospirosis and bacterial septic shock, among others.

    Objective To assess the effectiveness of acute geriatric units compared with conventional care units in adults aged 65 or more admitted to hospital for acute medical disorders. Design Systematic review and meta-analysis. Data sources Medline, Embase, and the Cochrane Library up to 31 August 2008, and references from published literature. Review methods Randomised trials, non-randomised trials, and case-control studies were included. Exclusions were studies based on administrative databases, those that assessed care for a single disorder, those that evaluated acute and subacute care units, and those in which patients were admitted to the acute geriatric unit after three or more days of being admitted to hospital. Two investigators independently selected the studies and extracted the data. Results 11 studies were included of which five were randomised trials, four non-randomised trials, and two case-control studies. The randomised trials showed that compared with older people admitted to conventional care units those admitted to acute geriatric units had a lower risk of functional decline at discharge (combined odds ratio 0.82, 95% confidence interval 0.68 to 0.99) and were more likely to live at home after discharge (1.30, 1.11 to 1.52), with no differences in case fatality (0.83, 0.60 to 1.14). The global analysis of all studies, including non-randomised trials, showed similar results. Conclusions Care of people aged 65 or more with acute medical disorders in acute geriatric units produces a functional benefit compared with conventional hospital care, and increases the likelihood of living at home after discharge.

    Atractyloside (ATR) and carboxyatractyloside (CATR) are diterpene glycosides that are responsible for the toxicity of several Asteraceae plants around the world. Mediterranean gum thistle (Atractylis gummifera L.) and Zulu impila (Callilepis laureola DC.), in particular, are notoriously poisonous and the cause of many accidental deaths, some suicides and even some murders. There is no current method for measuring the two toxins in biological samples that meet the criteria of specificity required in forensic medicine. We have endeavored to fill this analytical gap. Analysis was carried out using a solid-phase extraction and a high-performance liquid chromatography coupled with high-resolution tandem mass spectrometry detection. The method was validated in the whole blood with quantification limits of 0.17 and 0.15 µg/L for ATR and CATR, respectively. The method was applied to a non-fatal case of intoxication with A. gummifera. To the best of the authors' knowledge, this is the first time that a concentration of ATR and CATR in blood (883.1 and 119.0 µg/L, respectively) and urine (230.4 and 140.3 µg/L, respectively) is reported. ATR and CATR were quantified in A. gummifera roots by the standard method addition (3.7 and 5.4 mg/g, respectively).

    Fusarium species are environmental saprophytic fungi. Among the many Fusarium species, members of the Fusarium solani species complex (FSSC) are the most prevalent and virulent in causing human and animal infections. In this study, we describe the first case of fatal FSSC infection in a black spotted stingray and three concomitant infections in scalloped hammerhead sharks. In the stingray, cutaneous lesions were characterised by ulcers and haemorrhage of the ventral pectoral fin, or 'ray', especially around the head; while cutaneous lesions in the sharks were characterised by ulcers, haemorrhage, as well as white and purulent exudates at the cephalic canals of the cephalofoil and lateral line. Histological sections of the cutaneous lesions revealed slender (1-4 μm in diameter), branching, septate fungal hyphae. Internal transcribed spacer region and 28S nrDNA sequencing of the fungal isolates from the fish showed two isolates were F. keratoplasticum (FSSC 2) and the other two were FSSC 12. Environmental investigation revealed the FSSC strains isolated from water and biofilms in tanks that housed the elasmobranchs were also F. keratoplasticum and FSSC 12. Fusarium is associated with major infections in elasmobranchs and FSSC 12 is an emerging cause of infections in marine animals. DNA sequencing is so far the most reliable method for accurate identification of Fusarium species.

    A database of lightning-related fatalities and injuries in Turkey was constructed by collecting data from the Turkish State Meteorological Service, newspaper archives, European Severe Weather Database, and the internet. The database covers January 1930 to June 2014. In total, 742 lightning incidents causing human fatalities and injuries were found. Within these 742 incidents, there were 895 fatalities, 149 serious injuries, and 535 other injuries. Most of the incidents (89 %) occurred during April through September, with a peak in May and June (26 and 28 %) followed by July (14 %). Lightning-related fatalities and injuries were most frequent in the afternoon. Most of the incidents (86 %) occurred in rural areas, with only 14 % in the urban areas. Approximately, two thirds of the victims with known gender were male. Because of the unrepresentativeness of the historical data, determining an average mortality rate over a long period is not possible. Nevertheless, there were 31 fatalities (0.42 per million) in 2012, 26 fatalities (0.35 per million) in 2013, and 25 fatalities (0.34 per million) in 2014 (as of June). There were 36 injuries (0.49 per million) in each of 2012 and 2013, and 62 injuries (0.84 per million) in 2014 (as of June).

  4. Probable fatal drug interaction between intravenous fenretinide, ceftriaxone, and acetaminophen: a case report from a New Approaches to Neuroblastoma (NANT) Phase I study

    PubMed Central

    2014-01-01

    Background Patients with relapsed/refractory stage 4 high-risk neuroblastoma were enrolled on a phase I study (NANT2004-03) of intravenous fenretinide emulsion. Pharmacokinetic samples were collected during and after the infusion, and the levels were measured using an HPLC system. A likely case of a fatal drug interaction between fenretinide, ceftriaxone, and acetaminophen is described, including the pharmacokinetics of fenretinide, laboratory data, and post-mortem autopsy in a pediatric neuroblastoma patient treated on this study. Case presentation On Day 4 of a scheduled 5-day-infusion of intravenous fenretinide, the patient developed a fever, acetaminophen was started, ceftriaxone initiated for possible bacteremia, and fenretinide level doubled from 56 to 110 μM. Over the next three days, although blood cultures remained negative, the patient’s condition deteriorated rapidly. Acute liver failure was diagnosed on Day 7, and the patient expired on Day 20 of fulminant hepatic failure with associated renal, cardiac, and hemorrhagic/coagulation toxicities. Autopsy showed extensive hemorrhagic necrosis of the liver, marked bile duct proliferation, and abundant hemosiderin, consistent with cholestasis and drug toxicity. Conclusions After extensive review of patient data, the clinical course, and the literature, we conclude that observed hepatic toxicity was likely due to a drug interaction between fenretinide and concomitant ceftriaxone and acetaminophen. None of the other 16 patients treated on this study experienced significant hepatic toxicity. Although the prevalence of cholestasis with ceftriaxone usage is relatively high, the potential drug interaction with these concomitant medications has not been previously reported. Concomitant use of fenretinide, ceftriaxone, and acetaminophen should be avoided. PMID:24755475

    Despite an improved understanding of traumatic head and neck injury mechanisms, the impact tests required by major motorcycle helmet standards have remained unchanged for decades. Development of new test methods must reflect the specific impact loads causing injury in real crashes as well as test criteria appropriate for the observed injury profiles. This study analysed a collection of in-depth crash investigations of fatally injured helmeted riders in the Adelaide metropolitan region between 1983 and 1994 inclusive to review the head and neck injury patterns that resulted from specific types of impact. Inertial brain injury was sustained in 49% of examined cases, most often resulting from facial impacts but also in a large proportion of tangential, run over, and occipital impact cases. Focal brain and brainstem injury was also common (53%) and regularly associated with skull vault (11/12) and skull base fractures (22/31). Prevention of these fractures in impacts outside the area of required protection and in impacts with a straight edge would provide a significant increase in helmeted rider protection. Cervical spinal cord injury was sustained in facial, straight edge, and tangential impacts on the head. Motorcycle helmets are effective for preventing local skull fractures in impacts for which they are designed, whereas other serious injuries such as basilar skull fracture (BSF) and inertial brain injury persist despite helmet protection. Further impact test procedures should be developed for injurious impact types not currently assessed by major helmet standards, in particular facial impacts, and using test criteria based on commonly observed injuries. This study provides the necessary link, from impact load to injury, for guiding impact test development.

    Maltreatment of the elderly is a common problem that affects more than 3% of the elderly. We report on two cases of fatal neglect. Risk factors of victims and caregivers were analysed in the context of the social history. In both cases, the victims had a dominant personality and the abusers (the sons) had been strictly controlled and formed by the parent. The victims showed typical risk factors such as living together with the abuser, isolation, dependence on care, income and money administration. Initially, the victims declined help from outside and self-neglect occurred. The unemployed perpetrators lived in social isolation and depended financially and mentally on the victims. In both cases no mental illness was present but there was a decrease of social competence. Legal medicine is predominantly involved in fatal cases in connection with external post-mortem examinations and autopsies. Also in the living, the medico-legal expert can assist in the identification of findings in elderly persons in cases of suspected abuse.

    Chromobacterium violaceum is a rare human pathogen that causes potentially fatal infections especially in the tropical regions. Limited awareness about this pathogen and inappropriate antibiotic therapy are some of the factors contributing to the high mortality rate. To date there have been only eight cases reported from India of which only one is an adult. To the best of our knowledge, we report here the first case of a 40-year-old man from South India with septicemic C. Violaceum infection and septic arthritis.

    Case polarity design choices are discussed. Two examples of case-negative designs are presented. One battery is thionyl chloride limited and the other is lithium limited. The case-positive design is thionyl chloride limited. It is found that the case-positive/case-negative design consideration does not seem to have much bearing on storage. However, during low rate discharge, the case-negative cells show a steadily decreasing capacity as you go to lower and lower rates.

    Fatal exposure to poisonous plants in northern Europe is a rare condition. In this case report we describe an intended poisoning with Aconitum napellus (monkshood), which contains the toxin aconitine. The lethal dose in adults is 3-6 mg. The toxin affects excitable cells such as neurons and myocytes causing degrees of unconsciousness, hypotension and cardiac arrhythmias. There is no antidote and treatment is symptomatic. We describe a patient who had eaten monkshood. She was treated with infusion of lidocaine and survived. After 24 hours of treatment and monitoring she was discharged from the intensive care unit.

    Indigo, also known in Morocco as Nila, is a dye widely used in the coloring of Moroccan handicrafts. It is obtained from fermentation reactions on the leaves and branches of true indigo, Indigofera tinctoria, which is a widespread plant in tropical Africa and Asia. We report a case of fatal poisoning in a 3-year-old child after administration of indigo for therapeutic purposes. Death resulted from multiple organ failure. The toxicity of this compound is little known in the literature and deserves to be explored through toxicokinetic and toxicodynamic studies, in order to better determine the toxic constituents of the dye.

    Background In Spain, more than 85% of coronary heart disease deaths occur in adults older than 65 years. However, coronary heart disease incidence and mortality in the Spanish elderly have been poorly described. The aim of this study is to estimate the ten-year incidence and mortality rates of myocardial infarction in a population-based large cohort of Spanish elders. Methods A population-based cohort of 3729 people older than 64 years old, free of previous myocardial infarction, was established in 1995 in three geographical areas of Spain. Any case of fatal and non-fatal myocardial infarction was investigated until December 2004 using the "cold pursuit method", previously used and validated by the the WHO-MONICA project. Results Men showed a significantly (p < 0.001) higher cumulative incidence of myocardial infarction (7.2%; 95%CI: 5.94-8.54) than women (3.8%; 95%CI: 3.06-4.74). Although cumulative incidence increased with age (p < 0.05), gender-differences tended to narrow. Adjusted incidence rates were higher in men (957 per 100 000 person-years) than in women (546 per 100 000 person-years) (p < 0.001) and increased with age (p < 0.001). The increase was progressive in women but not in men. Adjusted mortality rates were also higher in men than in women (p < 0.001), being three times higher in the age group of ≥ 85 years old than in the age group of 65-74 years old (p < 0.001). Conclusion Incidence of fatal and non-fatal myocardial infarction is high in the Spanish elderly population. Men show higher rates than women, but gender differences diminish with age. PMID:19778417

    A retrospective study of scuba decompression illness (DCI) and fatalities in the U.S. military community on Okinawa Island, Japan, was performed for 1989-95. Some 94 cases of diving DCI, including 10 cases of cerebral air-gas embolism (CAGE), and 9 diving fatalities were reported, for an annual incidence of 13.4 DCI events and 1.3 fatalities per 100,000 dives. The overall estimated incidence of scuba DCI was estimated to be 1/7400 dives, with an annual incidence of undeserved DCI of 1/37,300, and a fatality rate of 1/76,900. A review of treatment dives revealed a 10% overdiagnosis rate in cases treated for presumed DCI. A bimodal distribution of DCI accidents was observed for depths deeper or shallower than 24.6m/80FSW (feet of sea water). Increased risk of DCI in diving deeper than 24.6m/80FSW was associated with violations of no-decompression limits (NDL), while other risk factors were associated with diving to less than 24.6m/80FSW. NDL violations accounted for only 24/94 (26%) of all DCI accidents. Treatment of divers with hyperbaric oxygen (HBOT) led to complete recovery in 91% of cases, but of those divers requiring retreatment with HBOT, 67% had chronic residua of DCI. Selected illustrative and interesting cases are discussed.

    Farm tractors are the major cause of occupational fatalities in agricultural regions. Fatalities typically result from being run over or crushed by the tractor, becoming entangled in the moving parts of the tractor, accidents on roadways, and tractor rollovers, which involve the tractor tipping sideways or backwards and crushing the operator. In this study, tractor-related fatalities in the Konya province of Turkey are retrospectively evaluated. Out of the 3940 cases on which a death examination and/or autopsy was performed between the years 2000 and 2007 at The Konya Branch of Forensic Medicine Council, 86 (2.2%) of the death cases were caused by tractor accidents and are included in this study. The ages of the victims varied between 3 and 80 years old with a mean age of 31.7 + or - 22.3. Sixty-eight (79.1%) of the cases involved males, while 18 (20.9%) of the cases involved females. In 32 (37.2%) of the cases, the deaths due to tractor accidents occurred when the tractor overturned. In 37 (43.0%) of the cases, the tractor-related fatalities involved the passengers and the drivers were involved in 34 (39.5%) of the cases. In conclusion, tractor accidents are preventable and deaths from tractor accidents can be significantly reduced if drivers are required to wear safety belts and helmets and frequent checks are implemented to enforce the ban on carrying passengers.

    Background This study provides a national profile of occupational fatalities among truck drivers and driver-sales workers. Methods Data from the 2003–2008 Census of Fatal Occupational Injuries were used. Cases were extracted specifically for occupational subcategories included in the Driver/Sales Workers and Truck Drivers occupational category: Driver/Sales Workers, Heavy and Tractor-Trailer Truck Drivers, and Light Truck or Delivery Services Drivers. Results In 2003–2008, the group Driver/Sales Workers and Truck Drivers had 5,568 occupational fatalities, representing 17% of all occupational fatalities in the United States. The majority of these fatalities were in the subgroup Heavy and Tractor-Trailer Truck Drivers (85%) and due to transportation incidents (80%). Older and male drivers had higher fatality rates than their counterparts. Conclusions Findings suggest a need for targeted interventions to reduce highway fatalities among heavy truck drivers. Better employment data are needed to separate the three occupational subcategories by worker characteristic and employment history for use in research and prevention efforts. PMID:24811905

    Background The adherence to long tuberculosis (TB) treatment is a key factor in TB control programs. Always some patients abandon the treatment or die. The objective of this study is to identify factors associated with defaulting from or dying during antituberculosis treatment. Methods Prospective study of a large cohort of TB cases diagnosed during 2006-2007 by 61 members of the Spanish Society of Pneumology and Thoracic Surgery (SEPAR). Predictive factors of completion outcome (cured plus completed treatment vs. defaulters plus lost to follow-up) and fatality (died vs. the rest of patients) were based on logistic regression, calculating odds ratios (OR) and 95% confidence intervals (CI). Results Of the 1490 patients included, 29.7% were foreign-born. The treatment outcomes were: cured 792 (53.2%), completed treatment 540 (36.2%), failure 2 (0.1%), transfer-out 33 (2.2%), default 27 (1.8%), death 27 (1.8%), lost to follow-up 65 (4.4%), other 4 (0.3%). Completion outcome reached 93.5% and poor adherence was associated with: being an immigrant (OR = 2.03; CI:1.06-3.88), living alone (OR = 2.35; CI:1.05-5.26), residents of confined institutions (OR = 4.79; CI:1.74-13.14), previous treatment (OR = 2.93; CI:1.44-5.98), being an injecting drug user (IDU) (OR = 9.51; CI:2.70-33.47) and treatment comprehension difficulties (OR = 2.93; CI:1.44-5.98). Case fatality was 1.8% and it was associated with the following variables: age 50 or over (OR = 10.88; CI:1.12-105.01), retired (OR = 12.26;CI:1.74-86.04), HIV-infected (OR = 9.93; CI:1.48-66.34), comprehension difficulties (OR = 4.07; CI:1.24-13.29), IDU (OR = 23.59; CI:2.46-225.99) and Directly Observed Therapy (DOT) (OR = 3.54; CI:1.07-11.77). Conclusion Immigrants, those living alone, residents of confined institutions, patients treated previously, those with treatment comprehension difficulties, and IDU patients have poor adherence and should be targeted for DOT. To reduce fatality rates, stricter monitoring is required

    A careful investigation of fatal accidents is required due to the relevant financial consequences for the insured as well as for the insurance company. An evaluation of post-mortem cases handled by our institute from 1988 to 1998 showed that 16% of all fatal accidents were not initially classified as such; it was only possible to determine the cause by post-mortem and criminal investigation. The frequency of a relevant alcoholization varied with different types of accidents. Furthermore, of all fatal accidents, 3% were revealed to be deceptive. Those 42 cases in total, presenting themselves as fatal accidents at first glance, were later determined either to be natural deaths (n = 27), homicide (n = 11) or suicide (n = 4). In addition to this, autopsies showed 83 cases of death to be sequelae to accidents. Particularly in cases of a victim plunging out of the window or into water, it can be difficult to make the distinction between natural death--e.g. as a reason for falling--and suicide or homicide. Further difficulties can result from interpretations of the findings in cases of putrefaction, mauling by animals, defects caused by burning or severely deformed corpses. In these cases, the importance of patho-morphological findings from the autopsy must be emphasized. Indirect sequelae of accidents may be pulmonary embolism or pneumonia. The cause of death has to be classified as accidental if the chain of events is of traumatic origin. Mistakes can be avoided if the medical history is taken conscientiously. If no facts are available, the cause of death should be certificated as undetermined. Our evaluation only included autopsy cases from our institute. The concealed fatal accidents which were incorrectly certified as natural deaths or the cases dismissed by the police and the public prosecutor without performing an autopsy were not evaluated.

    Estimates of the incidence of child maltreatment fatalities vary widely; most experts believe they are underreported. To investigate the suspicion that fatal maltreatment was underreported in Missouri preschool children, a statewide, population-based study was conducted using nine data sources. The study cases included the 384 children younger than age 5 who died from 1983 through 1986 and whose death certificates were coded with an external cause (injury) or whose deaths were substantiated as abuse or neglect fatalities by the Missouri Division of Family Services. Each fatality was categorized as one of the following: definite maltreatment, probable maltreatment, possible maltreatment, non-maltreatment, or inadequate information. Of the 121 cases classified as definite maltreatment, only 47.9% had codes consistent with maltreatment on their death certificates. The Division of Family Services had substantiated 79.3% of definite maltreatment cases as abuse or neglect fatalities. The Federal Bureau of Investigation Uniform Crime Reports database reported only 38.8% of these cases as homicides. In 37.2% of the cases, there was at least one criminal conviction. Child maltreatment fatalities are drastically underreported as such in Missouri because of inadequate investigations, lack of information-sharing between investigators and agencies, and reporting systems that fail to capture the contribution of maltreatment as a cause of death. Missouri has created a statewide system of child fatality review panels and a child fatality surveillance system to address the problems documented in this study.

    Lightning strike is a natural phenomenon with potentially devastating effects and represents one of the important causes of deaths from environmental phenomena. Almost every organ system may be affected as lightning current passes through the human body taking the shortest pathways between the contact points. A 10 years retrospective study (1996-2005) was conducted at University Hospital Kuala Lumpur (20 cases) also including cases during last 3 years from Hospital Tengku Ampuan Rahimah, Klang (7 cases) from the autopsy reports at Forensic Pathology Units of these 2 hospitals. Both these hospitals are attached to University of Malaya. There were 27 fatal cases of lightning strike with male preponderance(92.59%) and male to female ratio of 12.5:1. Majority of victims of lightning strike were from the age group between 30 and 39 years old. Most of the victims were foreign workers. Indonesians workers contributed to 59.26% of overall cases. Majority of them were construction workers who attributed i.e.11 of 27 cases (40.74%). Most of the victims were brought in dead (37.04%). In majority of the cases the lightning incidence occurred in the evenings, with the frequency of 15 of 27 cases (62.5%). The month of December represented with the highest number of cases (5 cases of 23 cases); 2004 had the highest incidence of lightning strike which was 5 (19.23%). Lightning strike incidence occurred when victims had taken shelter (25.9%) under trees or shades. Lightning strike in open areas occurred in 10 of 27 cases (37.0%). Head and neck were the most commonly affected sites with the incidence of 77.78% and 74% respectively in all the victims. Only 29.63% of the cases presented with ear bleeding.

    BACKGROUND: The complete and accurate identification of fatal occupational injuries among the US work force is an important first step in developing work injury prevention efforts. Numerous sources of information, such as death certificates, Workers' Compensation files, Occupational Safety and Health Administration (OSHA) files, medical examiner records, state health and labor department reports, and various combinations of these, have been used to identify cases of work-related fatal injuries. Recent studies have questioned the effectiveness of these sources for identifying such cases. METHODS: At least 10 studies have used multiple sources to define the universe of fatal work injuries within a state and to determine the capture rates, or proportion of the universe identified, by each source. Results of these studies, which are not all available in published literature, are summarized here in a format that allows researchers to readily compare the ascertainment capabilities of the sources. RESULTS: The overall average capture rates of sources were as follows: death certificates, 81%; medical examiner records, 61%; Workers' Compensation reports, 57%; and OSHA reports 32%. Variations by state and value added through the use of multiple sources are presented and discussed. CONCLUSIONS: This meta-analysis of 10 state-based studies summarizes the effectiveness of various source documents for capturing cases of fatal occupational injuries to help researchers make informed decisions when designing occupational injury surveillance systems.

    Abstract Background Kazakhstan, a developing middle-income country, has the highest road traffic collision (RTC) mortality in the European Region. The aims of this study were to determine main characteristics of road traffic fatalities in Semey region, Kazakhstan and to compare findings with National data and middle-income European countries. Methods This descriptive surveillance study assesses RTC mortality rates and epidemiology in the Semey Region of East Kazakhstan Oblast. Data of all 318 road traffic fatalities form the Semey Regional Center for Forensic Medicine were analyzed for the 5-year period of January 1, 2006 through December 31, 2010. Results Over the study period, the average road traffic mortality in the Semey Region was 12.1 per 100,000 population with downward trend by 35.1% (p=0.002). The victims mean age was 37.1 (SD=17) years. Males predominated at 74.5%. Vehicle fatality was the most common mode of fatality at 61.3%. The majority of collisions, 53.1%, occurred on highways. Most victims, 67.3%, have died at the scene of collision; in 67.3% of fatalities, autopsies identified multiple injuries as cause of death. The high number of fatal collisions took place in “no snow” season (P<0.001), with an overall 5-years downward dynamic. Conclusion High proportion of males, pedestrians and car occupants among road traffic fatalities; high proportion of death on scene in case of highway collisions are specifics for Semey region, Kazakhstan. These findings can be used to formulate preventive strategies to reduce fatalities and to improve the medical care system for road traffic fatalities. PMID:26110146

    This presentation reviews flood-related fatalities in the United States between 1959 and 2013. Information on flood fatality victims and the flood-causing events was obtained from the National Climatic Data Center. The data collected included the date, time, location, and weather conditions and the gender and age of the flood victims. Long term trends in the numbers of fatalities and fatality rates were analyzed. For most of the states fatalities were largely caused by single catastrophic events. The analysis indicates that the standardized annual flood fatality rates are decreasing significantly for all states. Vehicle related fatalities represent more than 50% of flood fatalities for most of the states and can be as high as 77%. A combination of improved hydrometeorological forecasting, educational programs aimed at enhancing public awareness of flood risk and the seriousness of flood warnings, and timely and appropriate action by local emergency and safety authorities will help further reduce flood fatalities in Texas.

    Botulism commonly occurs when the anaerobic, gram-positive bacterium Clostridium botulinum, under suitable conditions, produces botulinum neurotoxins. Named A-F, these toxins are the immediate causative agent of the clinical symptoms of symmetrical, descending neurological deficits, including respiratory muscle paralysis. We present five cases of foodborne botulism occurring in Greenland, two with fatal outcome, caused by ingestion of tradionally preserved eider fowl. In the cases of the survivors, antitoxin and supportive care, including mechanical ventilation, were administered. In these cases recovery was complete. Microbiological assays, including toxin neutralization bioassay, demonstrated the presence of neurotoxin E in two survivors. The third survivor was shown by PCR to have the BoNT type E gene in faeces. This is the first report of cases of fatal botulism in Greenland. It underscores the importance of prompt coordinated case management effort in a geographically isolated area such as Greenland.

    In patients with venous thromboembolism (VTE), assessment of the risk of fatal recurrent VTE and fatal bleeding during anticoagulation may help to guide intensity and duration of therapy. We aimed to provide estimates of the case-fatality rate (CFR) of recurrent VTE and major bleeding during anticoagulation in a 'real life' population, and to assess these outcomes according to the initial presentation of VTE and its etiology. The study included 41,826 patients with confirmed VTE from the RIETE registry who received different durations of anticoagulation (mean 7.8 ± 0.6 months). During 27,110 patient-years, the CFR was 12.1% (95% CI, 10.2-14.2) for recurrent VTE, and 19.7% (95% CI, 17.4-22.1) for major bleeding. During the first three months of anticoagulant therapy, the CFR of recurrent VTE was 16.1% (95% CI, 13.6-18.9), compared to 2.0% (95% CI, 0-4.2) beyond this period. The CFR of bleeding was 20.2% (95% CI, 17.5-23.1) during the first three months, compared to 18.2% (95% CI, 14.0-23.2) beyond this period. The CFR of recurrent VTE was higher in patients initially presenting with PE (18.5%; 95% CI, 15.3-22.1) than in those with DVT (6.3%; 95% CI, 4.5-8.6), and in patients with provoked VTE (16.3%; 95% CI, 13.6-19.4) than in those with unprovoked VTE (5.5%; 95% CI, 3.5-8.0). In conclusion, the CFR of recurrent VTE decreased over time during anticoagulation, while the CFR of major bleeding remained stable. The CFR of recurrent VTE was higher in patients initially presenting with PE and in those with provoked VTE.

    Background Previous studies have indicated that patients with acute myocardial infarction (AMI) who have a history of peripheral arterial disease (PAD) have different characteristics and poorer outcomes than patients without PAD. However, data on short-term mortality are conflicting and it is unclear whether patients with PAD have a different scope of AMI symptoms or differences in pre-hospital delay time (PHDT) compared with patients without PAD. The objective of this study was to determine the associations between a history of PAD and presenting AMI symptoms, PHDT and 28-day case fatality in a population-based sample of patients with AMI. Design This was an observational study. Methods Information on history of PAD was obtained from the patients' medical records and their AMI symptoms were assessed by interviews with patients. Multivariable logistic regression models were used to determine the association of PAD with AMI symptoms and 28-day case fatality. A multivariable linear regression model was developed to examine the relations between PAD and PHDT. Results From the 5848 patients with AMI included in this study, 9.8% had a history of PAD. Patients with PAD were significantly less likely to report chest symptoms (odds ratio (OR) 0.52, 95% confidence interval (CI) 0.41-0.66) or pain in the upper left extremity (OR 0.67, 95% CI 0.54-0.84) than patients without PAD. PAD was significantly related with longer PHDT in patients <69 years of age ( p = 0.0117) and men ( p = 0.0104). A significantly higher 28-day case fatality (OR 2.09, 95% CI 1.47-2.96) was found in patients with PAD compared with patients without PAD. Conclusions Patients with PAD should receive comprehensive education on the possibility of atypical AMI symptoms and the need to call emergency medical services immediately.

    Training cases define clinical immersion for candidates and are essential to their education, progression, and graduation. While dropouts from treatment are expected, repeated dropouts can be detrimental to a candidate's education and progression. In a study of the rate and timing of dropout in 145 cases at the Columbia University Center for Psychoanalytic Training and Research, 40 percent of patients were found to have dropped out within the first twelve months of treatment, though converted cases were less likely to drop out than were new patients evaluated at intake. This high dropout rate raises many questions about the reasons for it and suggests that there are critical educational issues regarding supervision and/or regarding candidates' technique during the induction phase.

    Singapore, an island republic of over 5 million inhabitants, has 3.1 million workers. Most are employed in the service, finance and tourist/transport industry. Significant numbers work in manufacturing, construction and heavy industry. Following a series of construction and shipyard accidents with multiple deaths in 2004, the government announced its intention to reduce workplace fatalities from 4.9 to 2.5 per 100,000 by 2015. There was strong political will to achieve this target. The strategic approaches were to build workplace safety and health (WSH) capabilities; implement legislative changes with enforcement; promote benefits of WSH and recognize best practices, and enhance partnership with stakeholders. The anticipated outcomes were to reduce workplace fatality and injury rates; have WSH as an integral part of business; and establish a progressive and pervasive WSH culture. With these measures, the workplace fatality rate declined from 4.9/100,000 in 2004, to 2.2/100,000 in 2010. However, other confounding factors could also account for this decline, and have to be considered. The next target, announced by Singapore's Prime Minister in 2008, is to further reduce the workplace fatality rate to 1.8/100,000 by 2018, and to have "one of the best workplace safety records in the world".

    Methanol poisoning has become a considerable problem in Iran. Liver can show some features of poisoning after methanol ingestion. Therefore, our concern was to examine liver tissue histopathology in fatal methanol poisoning cases in Iranian population. In this study, 44 cases of fatal methanol poisoning were identified in a year. The histological changes of the liver were reviewed. The most striking features of liver damage by light microscopy were micro-vesicular steatosis, macro-vesicular steatosis, focal hepatocyte necrosis, mild intra-hepatocyte bile stasis, feathery degeneration and hydropic degeneration. Blood and vitreous humor methanol concentrations were examined to confirm the proposed history of methanol poisoning. The majority of cases were men (86.36%). In conclusion, methanol poisoning can cause histological changes in liver tissues. Most importantly in cases with mean blood and vitreous humor methanol levels greater than 127 ± 38.9 mg/dL more than one pathologic features were detected.

    Autoerotic fatalities in the Greater Dusseldorf area correspond to the relevant medicolegal literature. Our results included exclusively young to middle-aged, usually single men who were found dead in their city apartments. Clothing and devices used showed a great variety. Women's or fetish clothing and complex shackling or hanging devices were disproportionately frequent. In most cases, death occurred due to hanging or ligature strangulation. There was no increased incidence of underlying psychiatric disorders. In most of the deceased no or at least no remarkable alcohol intoxication was found. Occasionally, it may be difficult to reliably differentiate autoerotic accidents, accidents occurring in connection with practices of bondage & discipline, dominance & submission (BDSM) from natural death, suicide or homicide.

  18. Fatal train accidents on Europe's railways: 1980-2009.

    2011-01-01

    This paper presents an analysis of fatal train accident rates and trends on Europe's main line railways from 1980 to 2009. The paper uses a new set of data for the European Union together with Norway and Switzerland, assembled partly under the auspices of the European Railway Agency and partly on the author's own account. The estimated overall trend in the number of fatal train collisions and derailments per train-kilometre is -6.3% per year from 1990 to 2009, with a 95% confidence interval of -8.7% to -3.9%. The estimated accident rate in 2009 is 1.35 fatal collisions or derailments per billion train-kilometres, giving an estimated mean number of fatal accidents in 2009 of 6.0. The overall number of fatalities per fatal accident in 1990-2009 is 4.10, with no apparent long term change over time, giving an estimated mean of 24.6 fatalities per year in train collisions and derailments in 2009. There are statistically significant differences in the fatal train accident rates and trends between the different European countries, although the estimates of the rates and trends for many individual countries have wide confidence limits. The distribution of broad causes of accidents appears to have remained unchanged over the long term, so that safety improvements appear to have been across the board, and not focused on any specific cause. The most frequent cause of fatal train collisions and derailments is signals passed at danger. In contrast to fatal train collisions and derailments, the rate per train-kilometre of serious accidents at level crossings remained unchanged in 1990-2009. The immediate causes of most of the serious level crossing accidents are errors or violations by road users.

    The objective of this study was to investigate road traffic crash injuries and fatalities. Cases of 3902 road traffic injuries (1709 drivers, 891 passengers, 376 pedestrians and 926 motorcyclists) and 1564 road traffic fatalities (RTFs; 1222 males and 342 females) were collected from 2005 to 2008 using the database of the police forces and Department of Forensic Medicine in Kerman, respectively. Results showed that 66% of the injuries were related to car occupants (drivers and passengers) and men/women ratio was 5:1. The highest men/women ratio was (12.2:1) for drivers, while the lowest ratio (1.8:1) was for pedestrians. Most of the injuries had taken place at 16:01-20:00 h followed by 08:01-12:00 h. Highest numbers of injuries were found in male with the age groups of 18-24 years. The highest fatality rate of 79 per 100,000 population occurred in 2007-2008. Fatality ratio indicated higher male ratio, four times higher than females. The victims were 39% male between 30 and 55 years of age. Head injuries were present in 69% of the cases. In our series of forensic autopsy cases, head injuries were more frequent in motor vehicle occupants, pedestrians and motorcyclists. On average, two people died per day in RTFs in Kerman.

    The present experimental investigations were inspired by the necessity of standardizing the procedures and analytical methods employed in hair analysis aiming at a retrospective evaluation of ingestion of various xenobiotics. Thus, in keeping with the principal premises, the main objective of the study was development of unique, novel chemico-toxicological procedures for analyzing hair content of psychoactive substances in two basic groups of substances of abuse: opioids (morphine, 6-monoacetylmorphine, codeine) and amphetamines (amphetamine, methamphetamine, MDA, MDMA, MDEA) by HPLC-APCI-MS-MS, followed by verification of the thus worked out procedures in medico-legal practice through opinionating in selected group of patients deceased due to fatal psychoactive substance poisoning (cause of death determination). Determinations of opioids and amphetamines in the hair biological matrix were performed using high performance liquid chromatography - atmospheric pressure chemical ionization - tandem mass spectrometry (HPLC-APCI-MS-MS). In the group of fatal poisonings by ,,Polish heroine", hair segmental analysis confirmed the abuse profile of the opiate or mixed (opiate-amphetamine) type, which to some measure is characteristic of Polish drug addiction, indicating the presence of these xenobiotics in the investigating hair samples in the premortem period.

    Methyl and ethyl alcohol poisoning are still responsible for high morbidity and mortality rates. The purpose of this retrospective study was to examine ethyl and methyl alcohol poisoning related deaths in Ankara and surrounding cities between 2001 and 2011 and compare them with previous studied conducted in Turkey and other countries. For this purpose, 10,720 medico-legal autopsy cases performed in Ankara Branch of the Council of Forensic Medicine were reviewed in terms of alcohol poisonings. The deaths due to methanol and ethanol poisoning were 74 (0.69% of all medico-legal autopsies performed) and the distribution among them was 35 (47.3%) for methanol poisoning and 39 (52.7%) for ethanol poisoning. Overwhelming majority of the cases were male (n = 67, 90.5%). The mean age of the victims was 44.9 ± 10.9 years and ranging from 21 to 92 years. The age group of 35-49 years was the mostly affected. Most of the cases were seen in 2004 (n = 12, 16.2%). The levels of postmortem blood alcohol levels were available for all cases and the mean alcohol levels were 322.8 ± 155.5 mg/dL ranging from 74 to 602 mg/dL for methanol and 396.8 ± 87.1 mg/dL and ranging from 136 to 608 mg/dL for ethanol. Early diagnosis is essential for successful treatment in methanol and ethanol poisoning. Besides increased awareness, more sensitive/specific diagnostic tools, and the prompt approach to the poisoned individual should be implemented in the hospitals.

    Over the past several decades, work-related fatal incident reporting in China has become faster, more publicly accessible and, hence, a potentially more valuable process in support of the decision-making and enforcement actions of the government and safety professionals. A study was conducted to examine the characteristics of work-related fatalities in the People's Republic of China (PRC) available from the State Work Accident Briefing (SWAB) system. Injury incident records related to industries other than coal mining were downloaded from the SWAB system (April 2001 to March 2003). The findings were compared with a previously published regional work fatality study in China, data from the U.S. Census of Fatal Occupational Injuries, and estimates from the International Labor Organization (ILO). During the 2-year period, 1538 work-related events (7046 worker fatalities) were recorded. Collisions (25.6%), drownings (14.6%), and structural collapses (12.5%) were the most frequently reported fatal events. Collisions (24.5%) and falls (14.5%) were the most frequent causes of cited fatal events. Transportation (105.87 per 100 000); mining industries other than coal mining and quarrying (73.28); and electricity, gas, and water supply (14.88) were the industries with the highest estimated fatality rates. Generally, regions with lower economic activity reported more fatalities. The fatal injury rate estimated from the SWAB system was 4.80 per 100,000 (U.S. rate 4.00). ILO estimates for 1994 and 2002 were substantially higher than the estimates derived from the SWAB system. SWAB system differences with other data sources analyzed herein indicate that there remains room for system refinement.

  6. Measurement and dimension of road fatality in Brunei.

    In this article, we have investigated the pattern of road fatality in Brunei. It is seen from this analysis that road fatality in Brunei was one of the highest in the world in the early 1990s, but has been significantly reduced over the years, and is now one of the lowest in the world. Preliminary investigation shows that young male drivers are responsible for most road fatalities in Brunei. We have also fitted a linear regression model and found that road fatality is significantly positively related to people aged 18-24 years and new registered vehicles, both of which are expected to grow with the growth of population and economic development. Hence, road fatality in Brunei is also expected to grow unless additional effective road safety countermeasures are introduced and implemented to reduce road toll. Negative coefficient is observed for trend variable, indicating the reduction of road fatality due to the combined effects of improvements of vehicle safety, road design, medical facilities and road safety awareness among road user groups. However, short-term road fatality analysis based on monthly data indicates that the coefficient of the trend variable is positive, implying that in recent months road fatalities are increasing in Brunei, which is supported by media reports. We have compared Brunei's road fatality data with Australia, Singapore and Malaysia and found that Brunei's road fatality rate is lower than Singapore and Malaysia, but higher than Australia. This indicates that there are still opportunities to reduce road fatalities in Brunei if additional effective road safety strategies are implemented like in Australia without interfering in the economic and social development of Brunei.

    Severe infections are a common cause of death in patients suffering from systemic lupus erythematosus (SLE). We here report on a fatal multidrug-resistant Acinetobacter baumannii sepsis in a patient with newly diagnosed SLE, who had to be treated with immunosuppressants due to lupus nephritis. Detailed analysis of the patient's history revealed that colonisation probably had occurred during a recent hospitalisation of the patient in the Mediterranean region. E-test analysis indicated that resistance to carbapenems was mediated by a plasmid-encoded metallo-beta-lactamase. We conclude that travel history including previously visited health care facilities always should be carefully considered for decisions on anti-infective therapy, as travel activities increasingly facilitate spread of antimicrobial resistances.

    Balamuthia mandrillaris , a free-living ameba, causes rare but frequently fatal granulomatous amebic encephalitis (GAE). Few patients have survived after receiving experimental drug combinations, with or without brain lesion excisions. Some GAE survivors have been treated with a multi-drug regimen including miltefosine, an investigational anti-leishmanial agent with in vitro amebacidal activity. Miltefosine dosing for GAE has been based on leishmaniasis dosing because no data exist in humans concerning its pharmacologic distribution in the central nervous system. We describe results of limited cerebrospinal fluid (CSF) and serum drug level testing performed during clinical management of a child with fatal GAE who was treated with a multiple drug regimen including miltefosine. Brain biopsy specimens, CSF, and sera were tested for B. mandrillaris using multiple techniques, including culture, real-time polymerase chain reaction, immunohistochemical techniques, and serology. CSF and serum miltefosine levels were determined using a liquid chromatography method coupled to tandem mass spectrometry. The CSF miltefosine concentration on hospital admission Day 12 was 0.4 μg/mL. The serum miltefosine concentration on Day 37, about 80 hours post-miltefosine treatment, was 15.3 μg/mL. These are the first results confirming some blood-brain barrier penetration by miltefosine in a human, although with low-level CSF accumulation. Further evaluation of brain parenchyma penetration is required to determine optimal miltefosine dosing for Balamuthia GAE, balanced with the drug’s toxicity profile. Additionally, the Balamuthia isolate was evaluated by real-time PCR, demonstrating genetic variability in18S rRNA sequences and possibly signaling the first identification of multiple Balamuthia strains with varying pathogenicities.

  9. Has the great recession and its aftermath reduced traffic fatalities?

    An analysis of state-level data from 1984 to 2014 provides evidence on the relationship between economic recessions and US traffic fatalities. While there are large reductions associated with decreases in household median income, other policy variables tend to have additional and in some cases, larger effects. An increase in the inequality of the income distribution, measured by the Gini index, has reduced traffic fatalities. Graduated licensing policies, cell phone laws, and motorcycle helmet requirements are all associated with reductions in fatalities. Other factors include a proxy for medical technology, and access to emergency medical services (based on the percent of vehicle miles traveled in rural areas); reductions in the latter accounted for a substantial reduction in fatalities and is likely another indicator of reduced economic activity. Changes in the road network, mainly increases in the percent of collector roads has increased fatalities. Population growth is associated with increased traffic fatalities and changes in age cohorts has a small negative effect. Overall, results suggest that there has been a beneficial impact on traffic fatalities from reduced economic activity, but various policies adopted by the states have also reduced traffic fatalities.

  10. Non-Fatal Suicidal Behaviors in Adolescents

    2004-01-01

    In the USA, suicide ranked as the third leading cause of death for adolescents in 1999. Non-fatal suicidal behaviours are suicidal thought, specific suicidal plan and suicide attempt. Prospective studies have emphasized the high subsequent suicide rates in clinically presenting suicide attempters. This study was planned to critically review the existing international literature on this area, and compare, if possible, with the Indian data. Both electronic and manual search for published and unpublished works was done for the review of this area. Both international and Indian studies on prevalence, risk factors, management, and prevention of non-fatal suicidal behaviours in adolescents were collected, analysed and reviewed. The study concludes that professionals, like general practitioners, paediatricians, school teachers, school counselors, need to be trained in identifying non-fatal suicidal behaviours in adolescents, and know when to refer them to a mental health professional or mental health service for thorough assessment and effective management. Timely and efficient management of non-fatal suicidal behaviors can prevent future suicidal attempts and completed suicide in most of this highly vulnerable population. Indian studies are very few and without robust study design. Systematic studies in India on this important topic are required. PMID:21206789

    Leptospirosis causes significant morbidity and mortality worldwide; however, the role of the host immune response in disease progression and high case fatality (>10–50%) is poorly understood. We conducted a multi-parameter investigation of patients with acute leptospirosis to identify mechanisms associated with case fatality. Whole blood transcriptional profiling of 16 hospitalized Brazilian patients with acute leptospirosis (13 survivors, 3 deceased) revealed fatal cases had lower expression of the antimicrobial peptide, cathelicidin, and chemokines, but more abundant pro-inflammatory cytokine receptors. In contrast, survivors generated strong adaptive immune signatures, including transcripts relevant to antigen presentation and immunoglobulin production. In an independent cohort (23 survivors, 22 deceased), fatal cases had higher bacterial loads (P = 0.0004) and lower anti-Leptospira antibody titers (P = 0.02) at the time of hospitalization, independent of the duration of illness. Low serum cathelicidin and RANTES levels during acute illness were independent risk factors for higher bacterial loads (P = 0.005) and death (P = 0.04), respectively. To investigate the mechanism of cathelicidin in patients surviving acute disease, we administered LL-37, the active peptide of cathelicidin, in a hamster model of lethal leptospirosis and found it significantly decreased bacterial loads and increased survival. Our findings indicate that the host immune response plays a central role in severe leptospirosis disease progression. While drawn from a limited study size, significant conclusions include that poor clinical outcomes are associated with high systemic bacterial loads, and a decreased antibody response. Furthermore, our data identified a key role for the antimicrobial peptide, cathelicidin, in mounting an effective bactericidal response against the pathogen, which represents a valuable new therapeutic approach for leptospirosis.

    Intimate partner violence (IPV) is an important cause of women's health and socio-familial severe problems, the most extreme being the victims' homicide. This is the first nationwide Portuguese autopsy-based and judicial-proven study about female intimate partner homicide. At least 62 women over 15 years old were killed by current or former men-intimate partners, corresponding to an IPV-related female mortality rate of 0.44/100.000 women; intimate partner violence was the reason of homicide in 60.8% of all autopsied women. The typical Portuguese victim showed to be a young adult woman, employed, killed by a current husband in a long-term relationship, usually with children in common and with a history of previous IPV. The typical Portuguese perpetrator showed to be older than the victim, employed, owning a firearm and without criminal records. At the time of the fatal event 59.7% of the relationships were current. In 57.9% of the former relationships women were killed during the 1st year after its terminus. Near half of the perpetrators attempted or committed suicide afterward. Most women were killed by gunshot wounds (45.2%), especially in the thorax (48.4%), with multiple fatal injuries; 56.5% also presented non-fatal injuries. The detection of prior IPV and the risk evaluation seems to be fundamental to decrease these fatal outcomes, but also, the prevention of perpetrators' alcohol abuse and carrying weapons. This work emphasizes the need to deepen the research on this issue, aiming to contribute to prevent both fatal and non-fatal IPV-related cases.

  14. Fiscal decentralisation and infant mortality rate: the Colombian case.

    There is a paucity of research analysing the influence of fiscal decentralisation on health outcomes. Colombia is an interesting case study, as health expenditure there has been decentralising since 1993, leading to an improvement in health care insurance. However, it is unclear whether fiscal decentralisation has improved population health. We assess the effect of fiscal decentralisation of health expenditure on infant mortality rates in Colombia. Infant mortality rates for 1080 municipalities over a 10-year period (1998-2007) were related to fiscal decentralisation by using an unbalanced fixed-effect regression model with robust errors. Fiscal decentralisation was measured as the locally controlled health expenditure as a proportion of total health expenditure. We also evaluated the effect of transfers from central government and municipal institutional capacity. In addition, we compared the effect of fiscal decentralisation at different levels of municipal poverty. Fiscal decentralisation decreased infant mortality rates (the elasticity was equal to -0.06). However, this effect was stronger in non-poor municipalities (-0.12) than poor ones (-0.081). We conclude that decentralising the fiscal allocation of responsibilities to municipalities decreased infant mortality rates. However, this improved health outcome effect depended greatly on the socio-economic conditions of the localities. The policy instrument used by the Health Minister to evaluate municipal institutional capacity in the health sector needs to be revised.

  15. More fatal all-terrain vehicle crashes occur on the roadway than off: increased risk-taking characterises roadway fatalities

    2013-01-01

    Background All-terrain vehicles (ATVs) have steadily increased in popularity, size and speed, characteristics that likely contribute to the alarming rise in ATV-related fatalities. One potentially high-risk activity is riding on the road. Objectives To compare fatal ATV crashes that occur on the roadway and off, to more fully understand factors that contribute to fatalities at each location. Methods Fatality data from the US Consumer Product Safety Commission (CPSC) were used for descriptive and comparative analyses. Multivariate logistic regression analysis was performed to determine relative risk. Results Over 60% of all fatalities (1985–2009) resulted from roadway crashes. After 1998, roadway fatalities increased at over twice the rate of off-road fatalities. Roadway crashes were more likely than off-road crashes to involve multiple fatalities, carrying passengers, alcohol use, collisions and head injuries. Roadway victims were less likely to be helmeted than off-road victims. Passengers and operators with passengers were also less likely to be helmeted than operators riding alone. Helmeted victims were half as likely to suffer a head injury. Conclusions Fatal roadway crashes were more likely than off-road crashes to involve risk-taking behaviours (eg, carrying passengers) that could exacerbate the inherent difficulty of operating ATVs on roadway surfaces. Higher crash forces from greater speed, and lower use of protective equipment, may also have contributed to higher roadway mortality rates. Eliminating non-essential ATV road use may be an effective way to reduce ATV-related fatalities. This will likely require a substantial investment in rider education and better enforcement of ATV road use restriction laws. PMID:23257569

    Objectives. We sought to determine the association between urban sprawl and traffic fatalities. Methods. We created a sprawl index by applying principal components analysis to data for 448 US counties in the largest 101 metropolitan areas. Regression analysis was used to determine associations between the index and traffic fatalities. Results. For every 1% increase in the index (i.e., more compact, less sprawl), all-mode traffic fatality rates fell by 1.49% (P < .001) and pedestrian fatality rates fell by 1.47% to 3.56%, after adjustment for pedestrian exposure (P < .001). Conclusions. Urban sprawl was directly related to traffic fatalities and pedestrian fatalities. Subsequent studies should investigate relationships at a finer geographic scale and should strive to improve on the measure of exposure used to adjust pedestrian fatality rates. PMID:12948977

  17. Estimating transport fatality risk from past accident data.

    PubMed

    Evans, Andrew W

    2003-07-01

    This paper examines the statistical properties of estimates of fatal accident rates, mean fatalities per accident, and fatality rates when these estimates are based on past accident data. The statistical properties are illustrated by two long-term transport fatal accident datasets from Great Britain, the principal one for railways and the other for roads, chosen to provide a statistical contrast. In both modes, the accident rates have fallen substantially over the long term. Two statistical estimates of current accident and fatality rates are presented for each dataset, one based only on recent data and the other based on estimates of long-term trends. The trend-based estimate is preferred for train accidents because this makes maximum use of the limited and variable data; the recent data are preferred for road accidents because this avoids unnecessary dependence on modelling the trends. For train accidents, the estimated fatality rate based on past accidents is compared with an estimate produced by the railway industry using a risk model. The statistical estimate is less than half the industry's estimate, and the paper concludes that the statistical estimate is to be preferred.

    Motor vehicle traffic crashes (MVTCs) remain the leading cause of work-related fatal injuries in the United States, with crashes on public roadways accounting for 25% of all work-related deaths in 2012. In the United States, the Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries (CFOI) provides accurate counts of fatal work injuries based on confirmation of work relationship from multiple sources, while the National Highway Traffic Safety Administration (NHTSA) Fatality Analysis Reporting System (FARS) provides detailed data on fatal MVTCs based on police reports. Characterization of fatal work-related MVTCs is currently limited by data sources that lack either data on potential risk factors (CFOI) or work-relatedness confirmation and employment characteristics (FARS). BLS and the National Institute for Occupational Safety and Health (NIOSH) collaborated to analyze a merged data file created by BLS using CFOI and FARS data. A matching algorithm was created to link 2010 data from CFOI and FARS using date of incident and other case characteristics, allowing for flexibility in variables to address coding discrepancies. Using the matching algorithm, 953 of the 1044 CFOI "Highway" cases (91%) for 2010 were successfully linked to FARS. Further analysis revealed systematic differences between cases identified as work-related by both systems and by CFOI alone. Among cases identified as work-related by CFOI alone, the fatally-injured worker was considerably more likely to have been employed outside the transportation and warehousing industry or transportation-related occupations, and to have been the occupant of a vehicle other than a heavy truck. This study is the first step of a collaboration between BLS, NHTSA, and NIOSH to improve the completeness and quality of data on fatal work-related MVTCs. It has demonstrated the feasibility and value of matching data on fatal work-related traffic crashes from CFOI and FARS. The results will lead to

    In July 2013, a passenger died of infectious extensively drug-resistant tuberculosis (XDR-TB) on board of an aircraft after a 3-hour flight from Turkey to Germany. Initial information indicated the patient had moved about the aircraft coughing blood. We thus aimed to contact and inform all persons exposed within the aircraft and to test them for newly acquired TB infection. Two-stage testing within 8 weeks from exposure and at least 8 weeks after exposure was suggested, using either interferon gamma release assays (IGRAs) or tuberculin skin test (TST). The TST cut-off was defined at a diameter > 10 mm; for differentiation between conversion and boosting, conversion was defined as increase of skin induration > 5 mm. Overall, 155 passengers and seven crew members were included in the investigation: the questionnaire response rate was 83%; 112 (69%) persons were tested at least once for TB infection. In one passenger, who sat next to the area where the patient died, a test conversion was registered. As of March 2017, no secondary active TB cases have been reported. We describe an unusual situation in which we applied contact tracing beyond existing European guidelines; we found one latent tuberculosis infection in a passenger, which we consider probably newly acquired.

    Tree shape analyses are frequently used to infer the location of shifts in diversification rate within the Tree of Life. Many studies have supported a causal relationship between shifts and temporally coincident events such as the evolution of “key innovations”. However, the evidence for such relationships is circumstantial. We investigated patterns of diversification during the early evolution of Amniota from the Carboniferous to the Triassic, subjecting a new supertree to analyses of tree balance in order to infer the timing and location of diversification shifts. We investigated how uneven origination and extinction rates drive diversification shifts, and use two case studies (herbivory and an aquatic lifestyle) to examine whether shifts tend to be contemporaneous with evolutionary novelties. Shifts within amniotes tend to occur during periods of elevated extinction, with mass extinctions coinciding with numerous and larger shifts. Diversification shifts occurring in clades that possess evolutionary innovations do not coincide temporally with the appearance of those innovations, but are instead deferred to periods of high extinction rate. We suggest such innovations did not cause increases in the rate of cladogenesis, but allowed clades to survive extinction events. We highlight the importance of examining general patterns of diversification before interpreting specific shifts. PMID:26592209

    Here, we describe a fatal serious adverse event observed in a patient infused with autologous T-cell receptor (TCR) transduced T cells. This TCR, originally obtained from a melanoma patient, recognizes the well-described HLA-A*0201 restricted 26-35 epitope of MART-1, and was not affinity enhanced. Patient 1 with metastatic melanoma experienced a cerebral hemorrhage, epileptic seizures, and a witnessed cardiac arrest 6 days after cell infusion. Three days later, the patient died from multiple organ failure and irreversible neurologic damage. After T-cell infusion, levels of IL-6, IFN-γ, C-reactive protein (CRP), and procalcitonin increased to extreme levels, indicative of a cytokine release syndrome or T-cell-mediated inflammatory response. Infused T cells could be recovered from blood, broncho-alveolar lavage, ascites, and after autopsy from tumor sites and heart tissue. High levels of NT-proBNP indicate semi-acute heart failure. No cross reactivity of the modified T cells toward a beating cardiomyocyte culture was observed. Together, these observations suggest that high levels of inflammatory cytokines alone or in combination with semi-acute heart failure and epileptic seizure may have contributed substantially to the occurrence of the acute and lethal event. Protocol modifications to limit the risk of T-cell activation-induced toxicity are discussed.

    Acinetobacter baumannii is the emerging cause of severe and often fatal gram-negative, community-acquired pneumonia (CAP-AB) in Thailand. Due to its rarity, its specific clinical features are ill defined. In this retrospective study, we compared the demographic data, risk factors, clinical characteristics, radiographic pattern, and microbiological data between CAP-AB and Burkholderia pseudomallei CAP (CAP-BP) to identify the clinical features and risk factors of CAP-AB. CAP-AB was associated with a more productive cough and a shorter duration of symptoms, while CAP-BP was associated with more musculoskeletal symptoms. The white blood cell and neutrophil counts were significantly lower in the CAP-AB group. Gram staining of the sputum revealed a significantly higher amount of bacteria in the CAP-AB group. Lobar infiltration and unilateral right lung involvement were the most common radiographic patterns in the CAP-AB group. CAP-AB is associated with severe pneumonia and has unique clinical features that distinguish it from CAP-BP.

    In order to enhance the emergency preparedness for large-scale floods of the Ara River, we categorized the inundation patterns and calculated fatality estimates. We devised an effective continuous embankment elevation estimation method employing light detection and ranging data analysis. Drainage pump capabilities, in terms of operatable inundation depth and operatable duration limited by fuel supply logistics, were modeled from pump station data of eac h site along the rivers. Fatality reduction effects due to the enhancement of the drainage capabilities were calculated. We found proper operations of the drainage facilities can decrease the number of estimat ed fatalities considerably in some cases. We also estimated the difference of risk between floods with 200 years return period and those with 1000 years return period. In some of the 1000 years return period cases, we found the estimated fatalities jumped up whereas the populations in inundated areas changed only a little.

    Aluminum phosphide (AlP) pesticide is a highly toxic, low cost, and easily accessible rodenticidal agent. Its toxicity results from the liberation of phosphine gas upon exposure to moisture, which leads to multisystem involvement, resulting in serious consequences. The highly toxic parathion insecticide was a common cause of mortality in pesticide fatalities, prior to its banning. Its toxicity was familiar to the public as well as to physicians. Recently, ten fatalities due to AlP were encountered within a three-month period during spring, when it was used as a rodenticide in the vicinity of grain stores. The victims' ages ranged from 1-34 years. The circumstances of death were accidental in six cases, suicidal in two and possibly homicidal in two cases. Retrospectively, the clinical manifestations, scene investigation, autopsy, histological and toxicological findings supported the diagnosis of AlP intoxication. Immediate recognition was difficult due to unfamiliarity of the agent to the physicians. The occurrence of these fatalities might suggest changes of pattern in pesticide poisoning. This should raise the attention of the physician to the problem of AlP poisoning and also necessitates the awareness of the public to the hazards of this poison. Education, proper handling, strict observation and abiding by the regulations controlling this material are good protective measures against AlP poisoning.

  6. An empirical model for global earthquake fatality estimation

    2010-01-01

    We analyzed mortality rates of earthquakes worldwide and developed a country/region-specific empirical model for earthquake fatality estimation within the U. S. Geological Survey's Prompt Assessment of Global Earthquakes for Response (PAGER) system. The earthquake fatality rate is defined as total killed divided by total population exposed at specific shaking intensity level. The total fatalities for a given earthquake are estimated by multiplying the number of people exposed at each shaking intensity level by the fatality rates for that level and then summing them at all relevant shaking intensities. The fatality rate is expressed in terms of a two-parameter lognormal cumulative distribution function of shaking intensity. The parameters are obtained for each country or a region by minimizing the residual error in hindcasting the total shaking-related deaths from earthquakes recorded between 1973 and 2007. A new global regionalization scheme is used to combine the fatality data across different countries with similar vulnerability traits. [DOI: 10.1193/1.3480331

    Tianeptine (Stablon), although structurally similar to tricyclic antidepressants, acts by enhancing the reuptake of serotonin. A fatal case is presented involving a 26-year-old man, found lying in bed with a "mushroom of foam" around his mouth. Empty blister packs of Stablon and a suicide note were found next to the body. A liquid-liquid extraction procedure with n-hexane: ethyl acetate and n-hexane: 2-propanol, followed by LC-DAD-MS analysis, using positive mode electrospray ionization was performed. The detection limit was 0.001 microg/mL. The toxicological results revealed the following tianeptine concentrations in the post-mortem samples: blood 5.1 microg/mL; urine 2.0 microg/mL; liver 23 microg/g; stomach contents 22 mg. Femoral blood analyses also revealed an ethanol concentration of 0.53 g/L. The present method was also developed and validated for the other post-mortem specimens, since no previous published data had confirmed the post-mortem distribution of tianeptine. The absence of other suitable direct causes of death (macroscopic or histological) and the positive results achieved with the toxicological analysis led the pathologist to rule that death was due to an intoxication caused by the suicidal ingestion of tianeptine in combination with alcohol.

    We describe three Israeli children with fatal spotted fever. Clinical disease was characterized by irreversible shock, encephalopathy, renal failure, bleeding tendency, and death within 24 hours of admission. None of the patients had a history of tick bite, and no tache noire was noted. One child presented without rash, and the other two did not have antibodies to spotted-fever-group rickettsiae. The disease was confirmed by isolation of Rickettsia conorii from the patients' blood and tissues in cell cultures or from susceptible laboratory animals inoculated with human specimens. The present cases demonstrate the existence of a severe form of Israeli spotted fever in this population that resembles Rocky Mountain spotted fever. Because Israeli spotted fever may follow a quick, unpredictable, rapidly fatal clinical course, specific antimicrobial therapy should be promptly administered whenever the diagnosis is suspected.

  10. The Effect of State Regulations on Truck-Crash Fatalities

    To improve traffic safety, states limit truck length and weight, and some set lower speed limits for trucks than for other vehicles. We examined the impact of truck-specific restrictions and general traffic-safety policies on fatality rates from crashes involving large trucks. We used state-level data from 1991 to 2005 with a cross-sectional time-series model that controlled for several policy measures. We found that higher speed limits for cars and trucks contributed to higher fatality rates, but differential speed limits by vehicle type had no significant impact. Truck-length limitations reduced fatalities in crashes involving large trucks. Our model estimates suggested that if all states had adopted a speed limit of 55 miles per hour for all vehicles in 2005, an additional 561 fatalities would have been averted. PMID:19150907

    Surveillance data suggest high rates of electrocutions and fatal falls among workers in electric utility companies, who may be exposed to electric current, heights, flammable agents, and frequent motor vehicle travel. To characterize the occurrence of fatal injuries among electric utility workers, we studied workers in five electric power companies in the United States. A cohort of 127,129 men hired between 1950 and 1986 was followed through 1988. Injuries at work were identified through manual review of death certificates. The occurrence of occupational injuries was analyzed with directly adjusted rates and Poisson regression. The overall rate of fatal occupational injuries was 13.20 per 100,000 person-years (n = 192), with 76% due to electric current, homicide, and falls from heights. Deaths were concentrated in a few groups with elevated injury rates, notably linemen (rate ratio (RR) 3.33), electricians (RR 2.79), and painters (RR 3.27). Occupations requiring daily work on elevations or frequent, direct contact with energized electrical equipment experienced markedly higher rates of fatal injury from falls and electrocutions with rate ratios of 21.8 (95% confidence interval (CI) 11.4-41.5) and 16.7 (95% CI 6.6-42.6), respectively, independent of worker age and seniority. Although fatal injury rates in this industry have declined in recent decades, significant numbers of deaths still occur. Based on the premise that all injuries are preventable, a need for continued vigilance and efforts at prevention is indicated.

    Human enterovirus 71 (EV-A71) causes hand, foot and mouth disease (HFMD). EV-A71 circulates in many countries and has caused large epidemics, especially in the Asia-Pacific region, since 1997. In April 2012, an undiagnosed fatal disease with neurological involvement and respiratory distress occurred in young children admitted to the Kantha Bopha Children's Hospital in Phnom Penh, Cambodia. Most died within a day of hospital admission, causing public panic and international concern. In this study, we describe the enterovirus (EV) genotypes that were isolated during the outbreak in 2012 and the following year. From June 2012 to November 2013, 312 specimens were collected from hospitalized and ambulatory patients and tested by generic EV and specific EV-A71 reverse transcription PCR. EV-A71 was detected in 208 clinical specimens while other EVs were found in 32 patients. The VP1 gene and/or the complete genome were generated. Our phylogenetic sequencing analysis demonstrated that 80 EV-A71 strains belonged to the C4a subgenotype and 3 EV-A71 strains belonged to the B5 genotype. Furthermore, some lineages of EV-A71 were found to have appeared in Cambodia following separate introductions from neighboring countries. Nineteen EV A (CV-A6 and CV-A16), 9 EV B (EV-B83, CV-B3, CV-B2, CV-A9, E-31, E-2 and EV-B80) and 4 EV C (EV-C116, EV-C96, CV-A20 and Vaccine-related PV-3) strains were also detected. We found no molecular markers of disease severity. We report here that EV-A71 genotype C4 was the main etiological agent of a large outbreak of HFMD and particularly of severe forms associated with central nervous system infections. The role played by other EVs in the epidemic could not be clearly established. PMID:27651091

    Tourism and fatal single motor vehicle accidents, an index of alcohol-related motor accidents, are examined in a cross-sectional analysis of the 50 states of the Union and the District of Columbia. A multiple regression model is employed in which average mileage driven, percent of metropolitan residents, and number of licensed drivers are statistically controlled. Tourism is found to be positively associated with the single motor vehicle fatality rate. Further research and policy implications are discussed.

    The occurrence of sporadic prion disease among adolescents is extremely rare. A prion disease was confirmed in an adolescent with disease onset at 13 years of age. Genetic, neuropathologic, and biochemical analyses of the patient’s autopsy brain tissue were consistent with sporadic fatal insomnia, a type of sporadic prion disease. There was no evidence of an environmental source of infection, and this patient represents the youngest documented case of sporadic prion disease. Although rare, a prion disease diagnosis should not be discounted in adolescents exhibiting neurologic signs. Brain tissue testing is necessary for disease confirmation and is particularly beneficial in cases with an unusual clinical presentation. PMID:24488737

    2006-03-01

    We present three cases of fatal dog maulings of infants placed in mobile infant swings, a phenomenon not previously described in the literature. In each case, the victim was left in a mobile swing, unsupervised by an adult, and the attacking dog was a family pet. Case 1 involved an 18-day-old male infant attacked by a pit bull; Case 2 involved a 3-month-old male infant attacked by a Chow Chow and/or a Dachshund, and Case 3 involved an 18-day-old female infant attacked by a Labrador-pit bull mix. These cases not only underscore the importance of not leaving young children unattended in the presence of pet dogs, but also raise the possibility that mobile swings may trigger a predatory response in dogs and thus may represent an additional risk factor for dog attack.

    Atypical clinical presentations associated with group W meningococcal disease (MenW) are well-described and include pneumonia, septic arthritis, endocarditis and epiglottitis/supraglottitis. Following anecdotal reports of teenagers presenting with predominantly gastrointestinal symptoms, we undertook a case review of MenW cases in 15 to 19 year-olds diagnosed in England between July 2015 and January 2016. Of the 15 cases, seven presented with a short history of nausea, vomiting and diarrhoea; five of these seven cases died within 24 hours of presentation to hospital.

    Apparently, fatal poisoning as cause of death are still rarely found in unnatural deaths investigated in the institutes of forensic medicine. In the Institute of Forensic Medicine at the University of Greifswald, 10-15% of the post-mortem autopsies displayed an intoxication during the last several decades with a possible decreasing tendency. Thirteen thousand eight hundred and nineteen autopsies were carried out in our institute-situated in a low populated rural area-during the last 50 years with the confirmed death cause intoxication in 1,589 times. In this study, especially the intoxication causes and the substance classes of the poisonous agents have been investigated. In addition, we analyzed the frequency of intoxications as well as sex and age of the deceased. Surprisingly, CO-intoxications were found most frequently with an incidence of 49% followed by alcohol intoxications with 21%. The latter was not unexpected taking into account the habits of the local population. Medical drugs and narcotics take only the third place, although the abuse of modern narcotics drugs is already visible even in the far east of Germany. The spectrum of substances which are abused, taken accidentally or deliberately is continuously changing, reflecting scientific progress in the pharmaceutical industry as well as fashion tendencies. Therapeutic use is almost always followed by abuse. Our results confirm prior experience concentrating mostly on other poisons like heavy metals or herbicides, etc. In addition, we could demonstrate the influence of political conditions on use and distribution of illegal drugs in Germany. Our study clearly demonstrates that insufficient equipment or analytical methods are no longer the reason for any problems uncovering lethal intoxications. They are rather due to insufficient investigations of the corpses (without considering the possibility of an intoxication as differential diagnosis) and to frequent mistakes of the prosecutor's office in death

  20. Clinical diagnosis versus autopsy findings in polytrauma fatalities

    PubMed Central

    2010-01-01

    Objectives The aim of the study was to determine if differences in clinical diagnosis versus autopsy findings concerning the cause of death in polytrauma fatalities would be detected in 19 cases of fatal polytrauma from a Level 1 trauma centre. Methods Clinical diagnoses determining the cause of death in 19 cases of fatal polytrauma (2007 - 2008) from a Level 1 trauma centre were correlated with autopsy findings. Results In 13 cases (68%), the clinical cause of death and the cause of death as determined by autopsy were congruent. Marginal differences occurred in three (16%) patients while obvious differences in interpreting the cause of death were found in another three (16%) cases. Five fatalities (three with obvious differences and two with marginal differences) were remarked as early death (1-4 h after trauma) and one fatality with marginal differences as late death (>1 week after trauma). Obvious and marginal discrepancies mostly occurred in the early phase of treatment, especially when severely injured patients were admitted to the emergency room undergoing continued cardiopulmonary resuscitation, i. e. limiting diagnostic procedures, and thus the clinical cause of death was essentially determined by basic emergency diagnostics. Conclusions Autopsy as golden standard to define the cause of death in fatal polytrauma varies from the clinical point of view, depending on the patient's pre-existing condition, mechanism of polytrauma, necessity of traumatic cardiopulmonary resuscitation, survival time, and thus the possibility to perform emergency diagnostics. An autopsy should be performed at least in cases of early fatal polytrauma to help establishing the definite cause of death. Moreover, autopsy data should be included in trauma registries as a quality assessment tool. PMID:20977732

    The study examines trends in bicycling fatalities reported to the Australian police between 1991 and 2013. Trends were estimated using Poisson regression modelling. Overall, cycling fatalities decreased by 1.9% annually between 1991 and 2013. However, while deaths following multivehicle crashes decreased at a rate of 2.9% per annum (95% CI -4.0% to -1.8%), deaths from single vehicle crashes increased by 5.8% per annum (95% CI 4.1% to 7.5%). Over the study period, the average age of cyclists who died in single vehicle crashes (45.3 years, 95% CI 41.5 to 49.1) was significantly higher than cyclists who died in multivehicle crashes (36.2 years, 95% CI 34.7 to 37.7). The average age of deceased cyclists increased significantly for both types of crashes. The observed increase in single vehicle crashes need to be closely monitored in Australia and internationally. In-depth studies are needed to investigate the circumstances of fatal single bicycle crashes in order to develop appropriate countermeasures.

    Autopsy is the traditional gold standard for determining the cause and manner of death in a forensic death investigation. However, postmortem imaging plays an ever-growing role in preliminary examination, even replacing conventional autopsy in some cases. This case report presents a case of massive intra-axial brain hemorrhage due to an arterio-venous malformation. The cause and manner of death were exclusively determined by postmortem radiology. Based on radiological findings, the autopsy was considered redundant and cancelled by the public prosecutor.

    Objective: To compare rates of motor vehicle crash (MVC) fatalities among different race/ethnic groups in urban and rural Arizona. Method: Using the Fatality Analysis Reporting System and the National Center for Health Statistics Multiple Cause of Death file, MVC fatalities in Arizona from 1990–96 inclusive were classified by gender, race/ethnicity, and urban or rural residence. Age adjusted rates of total, occupant, pedestrian, and alcohol related fatalities were calculated. The total MVC fatality rate for each race/ethnic group was then adjusted for proportion of rural residence. Results: Compared with non-Hispanic whites (NHWs), American Indians had raised relative risks for MVC fatality in all gender and residence subgroups. Hispanic females and rural Hispanic males had lower relative risks, as did rural African-American men. Raised relative risks for American Indian men and women included all subgroups: total, occupant, pedestrian, and alcohol related. Hispanic and African-American men both had raised relative risks of pedestrian related fatalities, and Hispanic men had a slightly higher relative risk while Hispanic women had a lower relative risks, for alcohol related fatality. Hispanic men and women and African-American men had lower occupant fatality rates. Close to half (45%) of the excess MVC fatality among American Indians can be attributed to residence in rural areas, where MVC fatality rates are higher. There were 1.85 occupants in crashes involving NHW deaths compared with 2.51 for Hispanics and 2.71 for American Indians (p<0.001). The proportion of occupants not using a seatbelt was higher in Hispanics and American Indians in both urban and rural areas. Conclusion: The major disparity in MVC fatality in Arizona is among American Indians. The higher MVC fatality rates among American Indians occur in all age groups, in both urban and rural areas, and among occupants and pedestrians. Rural residence, lower rates of seatbelt use, higher rates of

    Fatalities among Peace Corps volunteers were analyzed for 1962 through 1983, with individual case histories reviewed for all deaths from 1977 through 1983. Unintentional injuries accounted for 70% of the 185 deaths of Peace Corps volunteers, with motor vehicle crashes the number 1 cause of death. The death rate from unintentional injuries for women was significantly higher than the comparable US rate. Motorcycles caused 12% of all Peace Corps deaths and 33% of all motor vehicle deaths. Suicide has emerged as a leading cause of death among volunteers, accounting for 13% of all deaths from 1981 through 1983. Greater emphasis on injury control measures is needed to reduce this toll.

  6. The Role of Spatial Disorientation in Fatal General Aviation Accidents

    Scheuring, RIchard

    2005-01-01

    In-flight Spatial Disorientation (SD) in pilots is a serious threat to aviation safety. Indeed, SD may play a much larger role in aviation accidents than the approximate 6-8% reported by the National Transportation Safety Board (NTSB) each year, because some accidents coded by the NTSB as aircraft control-not maintained (ACNM) may actually result from SD. The purpose of this study is to determine whether SD is underestimated as a cause of fatal general aviation (GA) accidents in the NTSB database. Fatal GA airplane accidents occurring between January 1995 and December 1999 were reviewed from the NTSB aviation accident database. Cases coded as ACNM or SD as the probable cause were selected for review by a panel of aerospace medicine specialists. Using a rating scale, each rater was instructed to determine if SD was the probable cause of the accident. Agreement between the raters and agreement between the raters and the NTSB were evaluated by Kappa statistics. The raters agreed that 11 out of 20 (55%) accidents coded by the NTSB as ACNM were probably caused by SD (p less than 0.05). Agreement between the raters and the NTSB did not reach significance (p greater than 0.05). The 95% C.I. for the sampling population estimated that between 33-77% of cases that the NTSB identified as ACNM could be identified by aerospace medicine experts as SD. Aerospace medicine specialists agreed that some cases coded by the NTSB as ACNM were probably caused by SD. Consequently, a larger number of accidents may be caused by the pilot succumbing to SD than indicated in the NTSB database. This new information should encourage regulating agencies to insure that pilots receive SD recognition training, enabling them to take appropriate corrective actions during flight. This could lead to new training standards, ultimately saving lives among GA airplane pilots.

    The recent outbreaks of Chikungunya (CHIK-V) virus in endemic areas of dengue (DEN-V) could increase the risk of co-infection. CHIK infection has been considered not severe and with very unusual mortality, however DEN is associated with severe manifestations and increased mortality. Little is known about coinfection. It is possible that co-infection could generate severe cases. We present a case report of co-infection DEN-V -3 and CHIK-V in an elderly patient who developed acute renal failure, dengue shock syndrome (DSS), progresses to multiple organ failure and died. With the recent emergence of CHIK-V in Colombia, the possibility of co-infection with DEN-V should be suspected, especially in severe cases.

    Aluminium phosphide (AlP) is a cheap solid fumigant and a highly toxic pesticide which is commonly used for grain preservation. AlP has currently aroused interest with a rising number of cases in the past four decades due to increased use for agricultural and non-agricultural purposes. Its easy availability in the markets has increased also its misuse for committing suicide. Phosphine inhibits cellular oxygen utilization and can induce lipid peroxidation. Poisoning with AlP has often occurred in attempts to commit suicide, and that more often in adults than in teenagers. This is a case of suicidal consumption of aluminium phosphide by a 32-year-old young medical anesthetist. Toxicological analyses detected aluminium phosphide. We believe that free access of celphos tablets in grain markets should be prohibited by law. PMID:27486362

    Modifications to the investigation procedures in diving fatalities have been incorporated into the data acquisition by diving accident investigators. The most germane proposal for investigators assessing diving fatalities is to delay the drawing of conclusions until all relevant diving information is known. This includes: the accumulation and integration of the pathological data; the access to dive computer information; re-enactments of diving incidents; post-mortem CT scans and the interpretation of intravascular and tissue gas detected. These are all discussed, with reference to the established literature and recent publications.

    Death due to heroin overdose and/or rapid injection of heroin is a frequent occurrence among opioid addicts. We present an unusual case of heroin fatality due to the injection of the drug in the penis. Blood, urine, bile, and vitreous humor concentrations of morphine were 0.68, 0.49, 0.32 and 0.062 microg/ml, respectively. Ethanol was detected at concentrations of 104, 124, 106, and 94 mg/dl in the blood, urine, bile, and vitreous humor, respectively. The cause of death was determined to be due to heroin and ethanol intoxication.

    The study represents an attempt at employing segmental hair analysis in complex poisonings with xenobiotic mixtures of heroine - cocaine - amphetamines in the context of the cause of death as a consequence of complex interaction mechanisms which occurred prior to death. Two cases of complex poisonings: heroine - cocaine and heroine - cocaine - amphetamines were analyzed and documented with macro- and microscopic examinations and complex toxicological examinations, including the analysis of classic biological material, i.e. samples of selective blood, and alternative material, i.e. hair samples. Determinations of opioids, cocaine and its metabolite and amphetamines in the hair biological matrix were performed using high performance liquid chromatography--atmospheric pressure chemical ionization--tandem mass spectrometry (HPLC-APCI-MS-MS). Segmental hair analysis of the investigated cases indicated a prolonged intake of similar psychoactive substances and a developed adaptation of the addicted to interaction mechanisms, which, however, led gradually to multiorgan anatomopathological changes, and in consequence to death.

    2015-04-01

    Iatrogenic intestinal perforations in orthopaedic surgery are very rare. Reports of iatrogenic lesions caused by a guide wire during femur fracture osteosynthesis are even scarcer. There are no similar reports in recent literature. As opposed to what is normally described the lesion documented in this case report was not identified on time resulting in death by peritonitis. The forensic autopsy allowed the identification of an intestinal perforation with faecal leakage to peritoneal space in association with a vesical perforation enabling the reproduction of the guide wire path. In view of the increasing number of osteosynthesis it is essential for the surgeon to be aware of possible complications due to guide wire perforations. Cases like this go unnoticed if the forensic pathologist is not familiarized with the surgical technique which may explain the rarity of such descriptions in literature.

  15. Fatal intoxication with hydrocarbons in deltamethrin preparation.

    Pyrethroid insecticides are very widely used in agriculture and household due to high effectiveness and low toxicity to humans. We have described a case of a fatal oral intoxication with decis, the insecticide containing pyrethroid (deltamethrin) in a hydrocarbon base. Pyrethroids, including deltamethrin, undergo rapid biotransformation by liver enzymes, which limit their systemic toxicity. Thus, we assume that in the presented case, fatal outcome of poisoning with decis was rather connected with toxic effects of hydrocarbon base (solvent naphtha) than with deltamethrin action. In the described case, detection of aromatic hydrocarbons in blood and lung tissue and their metabolites in urine confirms that these substances were absorbed from gastrointestinal tract to the systemic circulation. Predominant among the clinical outcomes in our patient was profound depression of CNS with apnea, which could be connected with narcotic action of organic solvents. The cardiac arrest was in mechanism of asystolia with prior non-responsive to catecholamines bradycardia and vascular collapse. We connect it with hydrocarbon-induced cardiotoxicity. It is worth remembering that many pyrethroid-containing insecticides are formulated in a hydrocarbon base. Intoxication with such preparations should always be considered not only as poisoning with pyrethroid alone but also as intoxication with hydrocarbons.

    Cryptococcal meningoencephalitis is considered rare in HIV-negative individuals. In Madagascar, the epidemiology of cryptococcosis has not yet been well described, neither in immunocompetent nor in immunocompromised patients. We report here the first Malagasy detailed case of cryptococcal meningoencephalitis in a non-HIV immunocompromised adult patient carrying a low fluconazole susceptibility isolate. We emphasize the importance of early and accurate diagnosis to meet the challenges of managing cryptococcosis in developing countries. PMID:28078149

    Despite efforts to reduce their number, fatal diving accidents still occur. The circumstances and post-mortem findings in 40 fatal diving accidents in western Norway from 1983 through 2007 were investigated. Diving experience, medical history and toxicology reports were retrieved. The material consisted of recreational divers, professional saturation divers and professional divers without experience with saturation. In 33 cases the diving equipment was examined as part of the forensic investigation. In 27 cases defects in the diving equipment were found. For six divers such defects were responsible for the fatal accidents. Eighteen divers died on the surface or less than 10 m below surface. Five divers reached below 100 msw, and two of them died at this depth. The fatalities were not season-dependent. However, wave-height and strength of currents were influential factors in some cases. Twelve divers were diving alone. Twenty divers had one buddy, 9 of these divers were alone at the time of death. The cause of death was drowning in 31 out of 40 divers; one of them had a high blood-ethanol concentration, in two other divers ethanol was found in the urine, indicating previous ethanol consumption. Nine divers died from sudden decompression, pulmonary barotraumas, underwater trauma and natural causes. The study shows that most of the fatal diving accidents could be avoided if adequate diving safety procedures had been followed.

    Abstract: Background: Patterns of domestic violence fatalities and agency responses in Hawaii have not been explicated. Methods: Retrospective reviews of events leading up to domestic violence related fatalities in Hawaii were assessed from 45 adjudicated cases that resulted in 62 fatalities for the ten year period from 2000-2009. Results: Almost one-half of the fatalities were homicide/suicide combinations. Females were disproportionately more likely to be fatal victims of domestic violence relative to their proportion in the population. Those aged 21-40 years and those over 80 years were more likely to be fatal victims of domestic violence, relative to their proportion in the population. Filipinas and ‘Other” ethnic groups are disproportionately more likely to be fatal victims of domestic violence while Native Hawaiians and Japanese are less likely to be fatal victims, relative to their proportions in the population. In more than two-thirds of the cases, the victim had made some attempt to leave the relationship prior to the fatality. Conclusions: In the majority of cases there was agency involvement in some form: either the victim alone or the perpetrator alone, or both. However, less than one-third (31.1%) of the cases over the past ten years had documentation of prior violence from medical reports, so this may be an area to further document and address domestic violence.

    There is a rising trend of fatal poisonings due to medicinal opioids in several countries. The present study evaluates the drug and alcohol findings as well as the cause and manner of death in opioid-related post-mortem cases in Finland from 2000 to 2008. During this period, fatal poisonings by prescription opioids (buprenorphine, codeine, dextropropoxyphene, fentanyl, methadone, oxycodone, tramadol) increased as a share of all drug poisonings from 9.5% to 32.4%, being 22.3% over the whole period. A detailed study including the most prevalent opioids was carried out for the age group of 14-44 years, which is the most susceptible age for drug abuse in Finland. Poisonings by the weak opioids, codeine and tramadol, were found to be associated with large, often suicidal overdoses resulting in high drug concentrations in blood. Methadone poisonings were associated with accidental overdoses with the drug concentration in blood remaining within a therapeutic range. The manner of death was accidental in 43%, 55% and 94% of cases in codeine, tramadol and methadone poisonings, respectively. The median concentration of codeine and the median codeine/morphine concentration ratio were higher in codeine poisonings (1.4 and 22.5 mg/l, respectively) than in other causes of death (0.09 and 5.9 mg/l, respectively). The median concentrations of tramadol and O-desmethyltramadol were higher in tramadol poisonings (5.3 and 0.8 mg/l, respectively) than in other causes of death (0.6 and 0.2 mg/l, respectively). In methadone poisonings, the median concentration of methadone (0.35 mg/l) was not different from that in other causes of death (0.30 mg/l). Sedative drugs and/or alcohol were very frequently found in fatal poisonings involving these prescription opioids.

    Nontyphoid Salmonella (NTS) can cause invasive diseases in the elderly. Notably, the most feared complication of NTS bacteremia is endovascular infection. The risk factors for infected aortic aneurysm include old age and atherosclerosis. Extended use of antimicrobial therapy (> 2 weeks) for NTS bacteremia should be considered for those who demonstrate the risk factors for endovascular infection, even when a metastatic focus is clinically elusive. Herein, we report the case of a 75-year-old patient with diabetes mellitus, hypertension, chronic kidney disease, and myocardial infarction who died of an infected aortic aneurysm despite 3 weeks of antibiotic therapy that was administered to treat the initial NTS bacteremia.

    that mainly occurred in association with landslides and avalanches. The average age of victims of natural hazards was 35.9 years and, accordingly, the age groups with the largest number of victims were the 20-29 and 30-39 year-old groups, which in combination represented 34 % of all fatalities. It appears that the overall natural hazard mortality rate in Switzerland over the past 70 years has been relatively low in comparison to rates in other countries or rates of other types of fatal accidents in Switzerland. However, a large variability in mortality rates was observed within the country with considerably higher rates in Alpine environments.

    Hepatitis B virus (HBV) reactivation is a well-recognized complication that occurs in lymphoma patients who undergo chemotherapy. Only very few cases of HBV reactivation in patients with isolated antibody against hepatitis B surface antigen (anti-HBs) have been reported. We present a case of a 78-year-old woman diagnosed with diffuse large B cell non-Hodgkin's lymphoma who only displayed a positive anti-HBs, as the single possible marker of occult HBV infection, before starting therapy. She was treated with several chemotherapeutic regimens (including rituximab) for disease relapses during 3 years. Forty days after the last cycle of chemotherapy, she presented with jaundice, markedly elevated serum aminotransferase levels, and coagulopathy. HBV serology showed positivity for HBsAg, anti-HBc and anti-HBs. HBV DNA was positive. Antiviral treatment with entecavir was promptly initiated, but the patient died from liver failure. A review of the literature of HBV reactivation in patients with detectable anti-HBs levels is discussed.

  4. The turning point in the number of traffic fatalities: two hypotheses about changes in underlying trends.

    PubMed

    Brüde, Ulf; Elvik, Rune

    2015-01-01

    The number of traffic fatalities reached a peak in many highly motorised countries around 1970. Some previous studies have suggested that the turning point in the number of traffic fatalities was inevitable and did not reflect a change in the underlying trends influencing the number of traffic fatalities. Other studies suggest that trends in traffic growth and fatality rate changed from before to after the turning point. This paper proposes two hypotheses about the turning point in the number of traffic fatalities. One hypothesis is that the long-term trends in traffic growth and fatality rate were the same before and after the turning point. The other hypothesis is that the long-term trends in traffic growth and fatality rate were different before and after the turning point was reached, in particular that the annual percentage decline in fatality rate became greater after the turning point than before. Such a change would suggest that road safety policy became more effective. Analysis of data for six countries (Denmark, Great Britain, Netherlands, Norway, Sweden, United States) lends stronger support to the latter hypothesis than to the former. The lesson for policy makers, in particular in countries where the number of traffic fatalities is still growing, is that they should not expect a turning point to be reached without policy interventions.

    According to Portuguese law, if a case of intimate partner violence is noticed or suspected by a professional working in public services, reporting it to the police, medico-legal services or directly to the public prosecutor is mandatory. However, in most cases, reporting does not take place, despite its vital importance in triggering the multidisciplinary intervention that will ensure the correct and timely diagnosis and protection of the victim. In the present case, the victim, a 37 year-old woman, was sexually and physically abused by her husband in their home, and was physically abused again at the victim's mother's house. The victim mentioned that her husband struck her in the head with a hammer and shot a handgun while in her mother's house. However, she denied having a gunshot wound. The couple's daughter was also slapped in the face by her father. The police took the victim to the emergency room of a central hospital to receive medical attention, while the medical examiner on duty was called to the same emergency room to perform a medico-legal evaluation in the context of the intimate partner violence reported to the police. Medico-legal assessment revealed scalp injuries that had not been detected during the first inspection by the emergency room attending physicians who had performed a neurological examination, which revealed no neurological dysfunction. A cranial computed tomography with three-dimensional reconstitution and virtual dissection, requested by the medical examiner, revealed two projectiles trapped in between the inner and the outer table of the cranium, with linear fractures only in the inner table and no brain injuries. Gynecological examination with the collection of biological evidence, also performed by the medical examiner, made it possible to identify a male DNA profile matching her husband's. The victim was subjected to neurosurgery and a follow-up, and was released one month after the traumatic event. A forensic psychological

    A rapid colorimetric method for detection of p-phenylenediamine (PPD) in various biological samples is developed. The o-cresol test for acetaminophen detection has been modified to detect PPD in blood, urine, gastric contents, and liver. After precipitating protein with trichloroacetic acid solution (2 mL, 10% w/v), biological specimens were required to convert PPD metabolites to PPD by acid hydrolysis. Finally, o-cresol solution (1 mL, 1% w/v), hydrogen peroxide (200 μL, 3%v/v), and concentrated ammonium hydroxide (0.5 mL) were added in the biological samples. The presence of PPD was indicated by formation of violet color which was turned to bluish green color within 10-15 min. The limit of detection was found to be 2 mg/L in blood, urine, and gastric contents and 2 mg/Kg in liver. This method is also free from any potential interference by p-aminophenol, acetaminophen, and other amine drugs under test conditions. This method was successfully employed to thirteen fatal cases of PPD poisoning.

    The autopsy findings in fatal cases of railway collisions of the Bonn Institute of Legal Medicine in 1992-1999 were investigated and compared to the statements in the investigation files of the public prosecutor with regard to classification as accident or suicide as well as with regard to type and speed of collision. Of the 38 deaths, 10 were hit in an upright position, 11 fatal collisions affected persons lying outside the track and 13 were hit and overrun lying inside the track. According to the investigation classification 21 persons committed suicide (56%), while 10 died in an accident (26%). Our survey confirmed the leading role of being over-rolled in a lying position as an indication for suicides, while in accidents the upright hit was most important. With exception of the persons primarily affected between the rails in upright position and over-rolled consecutively an unequivocal assignment of injury patterns to the hit categories was possible. In cases of persons being primarily over-rolled in a lying position especially the criteria (i) opening of body cavities, (ii) organ injuries and (iii) loss of parts of the body allowed for careful conclusion on hit, respectively, overrunning speed.

    Histopathologic features of New Mexico 2009 H1N1 fatalities have not been representative of those reported nationwide. We retrospectively reviewed medical records of all New Mexico 2009 pandemic influenza A (pH1N1) fatalities (n = 50). In cases in which autopsy was performed (n = 12), histologic sections and culture results were examined. In contrast to previously published studies, the majority of our fatalities did not have diffuse alveolar damage (DAD) (2/12; 16.7%). Common findings included pulmonary interstitial inflammation and edema, tracheobronchitis, and pneumonia. Two cases had significant extra-pulmonary manifestations: myocarditis and cerebral edema with herniation. The majority had a rapid disease course: range from 1 to 12 days (median, 2 days), and Native Americans were disproportionately represented among fatalities. These findings suggest that New Mexico H1N1 fatalities generally did not survive long enough to develop the classic picture of DAD. Pathologists should be aware that H1N1 may cause extra-pulmonary pathology and perform postmortem cultures and histologic sampling accordingly.

    In this work, a case of deliberate self-poisoning is presented. A 14-year-old girl suddenly died during one of the several hospitalizations. Abdominal computer tomography showed a large number of metallic particles in the large intestine. Analysis of blood and internal organs for mercury and other toxic metals carried out by inductively coupled plasma optical emission spectrometry (ICP OES) revealed high concentrations of mercury in kidneys and liver (64,200 and 2470ng/g, respectively), less in stomach (90ng/g), and none in blood. Using cold vapor-atomic absorption spectrometry (CV AAS), high levels of mercury were confirmed in all examined materials, including blood (87ng/g), and additionally in hair. The results of analysis obtained by two techniques revealed that the exposure to mercury was considerable (some time later, it was stated that the mercury originated from thermometers that had been broken over the course of about 1 year, because of Münchausen syndrome). CV AAS is a more sensitive technique, particularly for blood samples (negative results using ICP OES), and tissue samples - with LOQ: 0.63ng/g of Hg (CV AAS) vis-à-vis 70ng/g of Hg (ICP OES). However, ICP OES may be used as a screening technique for autopsy material in acute poisoning by a heavy metal, even one as volatile as mercury.

    A woman in her thirties was found dead on a bed. Considerable amounts of "aroma liquid" and "bath salt" products and hypnotic drug tablets were scattered beside the bed. Autopsy showed pulmonary congestion and edema. Gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) analyses of "aroma liquid" and "bath salt" products showed the presence of new cathinone designer drugs, 4-methoxy PV8 (4-methoxy PHPP), PV9 (α-POP), and 4-methoxy PV9 (4-methoxy α-POP), and a dissociative agent, diphenidine. Drug screening in stomach contents, blood and hydrolyzed urine of the woman by GC-MS and liquid chromatography-tandem mass spectrometry (LC-MS/MS) revealed the presence of the above 4 types of drugs and 3 types of benzodiazepines, triazolam, flunitrazepam, and nitrazepam, and their metabolites. The above 7 drugs and 3 benzodiazepine metabolites were simultaneously determined by LC-MS/MS after modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) extraction using diazepam-d5 as the internal standard. The concentrations of 4-methoxy PV8, PV9, 4-methoxy PV9, and diphenidine in the femoral blood were 2.69, 0.743, 0.261, and 1.38μg/ml, respectively, which were significantly higher than concentrations reported in previous cases. Alcohol concentration in the femoral blood was 1.52mg/ml. Based on the pathological and toxicological findings, the cause of death was determined to be 3 types of cathinone drugs, 4-methoxy PV8, PV9, and 4-methoxy PV9, and diphenidine poisoning under the influence of 3 benzodiazepines and alcohol.

    We present the case histories, autopsy findings and toxicology findings of two fatal intoxications involving the designer drug, butyryl fentanyl. The quantitative analysis of butyryl fentanyl in postmortem fluids and tissues was performed by an ultrahigh-performance liquid chromatography tandem mass spectrometry method. In the first case, butyryl fentanyl was the only drug detected with concentrations of 99 ng/mL in peripheral blood, 220 ng/mL in heart blood, 32 ng/mL in vitreous humor, 590 ng/mL in gastric contents, 93 ng/g in brain, 41 ng/g in liver, 260 ng/mL in bile and 64 ng/mL in urine. The cause of death was ruled fatal intoxication by butyryl fentanyl. In the second case, butyryl fentanyl was detected along with acetyl fentanyl, alprazolam and ethanol. The butyryl fentanyl concentrations were 3.7 ng/mL in peripheral blood, 9.2 ng/mL in heart blood, 9.8 ng/mL in vitreous humor, 4,000 ng/mL in gastric contents, 63 ng/g in brain, 39 ng/g in liver, 49 ng/mL in bile and 2 ng/mL in urine. The acetyl fentanyl concentrations were 21 ng/mL in peripheral blood, 95 ng/mL in heart blood, 68 ng/mL in vitreous humor, 28,000 ng/mL in gastric contents, 200 ng/g in brain, 160 ng/g in liver, 330 ng/mL in bile and 8 ng/mL in urine. In addition, the alprazolam concentration was 40 ng/mL and the ethanol concentration was 0.11 g/dL, both measured in peripheral blood. The cause of death in the second case was ruled a mixed drug intoxication. In both cases, the manner of death was accident.

    Background Avalanches are a significant cause of winter recreational fatalities in mountain regions. The purpose of this study was to determine the relative contributions of trauma and asphyxia to avalanche deaths. Methods We reviewed all avalanche fatalities between 1984 and 2005 that had been investigated by the offices of the British Columbia Coroners Service and the Chief Medical Examiner of Alberta. In addition, we searched the database of the Canadian Avalanche Centre for fatal avalanche details. We calculated injury severity scores for all victims who underwent autopsy. Results There were 204 avalanche fatalities with mortality information over the 21-year study period. Of these, 117 victims underwent autopsy, and 87 underwent forensic external examination. Asphyxia caused 154 (75%) deaths. Trauma caused 48 (24%) deaths, with the rate of death from trauma ranging from 9% (4/44) for snowmobilers to 42% (5/12) for ice climbers. In addition, 13% (12/92) of the asphyxia victims who underwent autopsy had major trauma, defined as an injury severity score of greater than 15. Only 48% (23/48) of victims for whom trauma was the primary cause of death had been completely buried. Interpretation Asphyxia and severe trauma caused most avalanche fatalities in western Canada. The relative rates differed between snowmobilers and those engaged in other mountain activities. Our findings should guide recommendations for safety devices, safety measures and resuscitation.

    The diester-diterpene alkaloid aconitine was quantified by liquid chromatography-tandem mass spectrometry in post-mortem specimens of three cases where suicidal ingestion of Aconitum napellus L. ('monkshood') was supposed. In an attempt at rationalization, sample preparation and chromatographic conditions of plasma/serum drug analysis routine were utilized. Linearity was established from 0.5 to 20 µg L⁻¹ using newborn calf serum (NCS) as a surrogate calibration matrix for all sample types and mesaconitine as an internal standard. Validation (selectivity, sensitivity, precision, accuracy, recovery of the extraction procedure, matrix effect, processed sample stability) confirmed the applicability of the analytical method to various post-mortem matrices. Internal standard selection was based on multi-matrix process efficiency data. In human post-mortem peripheral blood a lower limit of quantification of 0.51 µg L⁻¹ and a limit of detection of 0.13 µg L⁻¹ were accomplished (0.1 ml sample aliquots). Aconitine was degraded to a large extent in different sample types when being stored at +20 °C for 30 days, while at -20 °C and for some matrices also at +4 °C no appreciable degradation occurred. Aconitine concentrations in real samples were 10.3-17.9 µg L⁻¹ (peripheral blood, n = 3), 14.9-87.9 µg L⁻¹ (heart blood, n = 3), 317-481 µg L⁻¹ (urine, n = 2), 609-4040 µg L⁻¹ (stomach content, n = 3), 139-240 µg L⁻¹ (bile, n = 2), 8.4 µg L⁻¹ (vitreous humor, n = 1), 54.7 µg L⁻¹ (pericardial fluid, n = 1), 492 µg kg⁻¹ (liver, n = 1), 15.2-19.7 mg L⁻¹ (unknown liquids secured onsite, n = 3). Together with concomitant circumstances the analytical data provided compelling evidence for acute Aconitum poisoning as being the cause of death.

    The Federal Columbia River Power System (FCRPS), operated on behalf of the ratepayers of the PNW by BPA and other Federal agencies, faces many uncertainties during the FY 2007-2009 rate period. Among these uncertainties, the largest revolve around hydro conditions, market prices and river operations for fish recovery. In order to provide a high probability of making its U.S. Treasury payments, BPA performs a Risk Analysis as part of its rate-making process. In this Risk Analysis, BPA identifies key risks, models their relationships, and then analyzes their impacts on net revenues (total revenues less expenses). BPA subsequently evaluates in the ToolKit Model the Treasury Payment Probability (TPP) resulting from the rates, risks, and risk mitigation measures described here and in the Wholesale Power Rate Development Study (WPRDS). If the TPP falls short of BPA's standard, additional risk mitigation revenues, such as PNRR and CRAC revenues are incorporated in the modeling in ToolKit until the TPP standard is met. Increased wholesale market price volatility and six years of drought have significantly changed the profile of risk and uncertainty facing BPA and its stakeholders. These present new challenges for BPA in its effort to keep its power rates as low as possible while fully meeting its obligations to the U.S. Treasury. As a result, the risk BPA faces in not receiving the level of secondary revenues that have been credited to power rates before receiving those funds is greater. In addition to market price volatility, BPA also faces uncertainty around the financial impacts of operations for fish programs in FY 2006 and in the FY 2007-2009 rate period. A new Biological Opinion or possible court-ordered change to river operations in FY 2006 through FY 2009 may reduce BPA's net revenues included Initial Proposal. Finally, the FY 2007-2009 risk analysis includes new operational risks as well as a more comprehensive analysis of non-operating risks. Both the operational

    Fatal dwelling-house fires account for 10% of all accidental deaths in the United Kingdom with one-quarter of the deaths being of elderly people. No study had described the characteristics of elderly individuals who die in fires. We report results from a retrospective review of all fatal dwelling-house fires in Scotland from 1980 to 1990. Of 1096 people dying in fires, 243 (23%) were aged over 75. When compared with patients under the age of 75, older patients were significantly less likely to be smokers. Significantly more fires killing elderly people were caused by faulty or misused electrical items in the house, particularly electric blankets. These differences between elderly and younger individuals dying in dwelling-house fires may suggest that preventive strategies for the elderly population require a different emphasis from those for younger people.

    2005-10-01

    We report a case of fatal outcome poisoning by massive exposure to hydrogen sulfide of a sewer worker. This rare event was associated with a moderate intoxication of two members of the rescue team. The death was due to asystole and massive lung oedema. Autopsy analysis showed diffuse necrotic lesions in lungs. Hydrogen sulfide is a direct and systemic poison, produced by organic matter decomposition. The direct toxicity mechanism is still unclear. The systemic toxicity is due to an acute toxicity by oxygen depletion at cellular level. It is highly diffusable and potentially very dangerous. At low concentration, rotten egg smell must trigger hydrogen sulfide suspicion since at higher concentration it is undetectable, making intoxication possible. In case of acute intoxication, there is an almost instantaneous cardiovascular failure and a rapid death. Hydrogen sulfide exposure requires prevention measures and more specifically the use of respiratory equipment for members of the rescue team.

    This paper investigates the role of race/ethnicity, language skills (a proxy for acculturation among Hispanics in Arizona, California, New Mexico, and Texas), income, and education level on alcohol-related fatal motor vehicle crashes. Using the Fatality Analysis Reporting System (FARS), we confirmed previous state-based studies showing that high income and education levels have a protective influence on alcohol-related fatal motor vehicle crashes. We also confirmed that language proficiency/acculturation tends to increase the vulnerability of Hispanic women to alcohol-related fatalities. Differences in alcohol-related fatality rates across Hispanic subgroups are observed. Future reductions in alcohol-related traffic fatalities may require prevention policies that take into account existent variations in acculturation, income, and education among racial/ethnic groups and subgroups.

  5. Fatal accidents at railway level crossings in Great Britain 1946-2009.

    Evans, Andrew W

    2011-09-01

    This paper investigates fatal accidents and fatalities at level crossings in Great Britain over the 64-year period 1946-2009. The numbers of fatal accidents and fatalities per year fell by about 65% in the first half of that period, but since then have remained more or less constant at about 11 fatal accidents and 12 fatalities per year. At the same time other types of railway fatalities have fallen, so level crossings represent a growing proportion of the total. Nevertheless, Britain's level crossing safety performance remains good by international standards. The paper classifies level crossings into three types: railway-controlled, automatic, and passive. The safety performance of the three types of crossings has been very different. Railway-controlled crossings are the best-performing crossing type, with falling fatal accident rates. Automatic crossings have higher accident rates per crossing than railway controlled or passive crossings, and the accident rates have not decreased. Passive crossings are by far the most numerous, but many have low usage by road users. Their fatal accident rate has remained remarkably constant over the whole period at about 0.9 fatal accidents per 1000 crossings per year. A principal reason why fatal accidents and fatalities have not fallen in the second half of the period as they did in the first half is the increase in the number of automatic crossings, replacing the safer railway controlled crossings on some public roads. However, it does not follow that this replacement was a mistake, because automatic crossings have advantages over controlled crossings in reducing delays to road users and in not needing staff. Based on the trends for each type of crossing and for pedestrian and non-pedestrian accidents separately, in 2009 a mean of about 5% of fatal accidents were at railway controlled crossings, 52% were at automatic crossings, and 43% were at passive crossings. Fatalities had similar proportions. About 60% of fatalities were

    Background Road traffic injuries (RTI) are a major public health epidemic killing thousands of people daily. Low and middle-income countries, such as Brazil, have the highest annual rates of road traffic fatalities. In order to improve road safety, this study mapped road traffic fatalities on a Brazilian highway to determine the main environmental factors affecting road traffic fatalities. Methods and Findings Four techniques were utilized to identify and analyze RTI hotspots. We used spatial analysis by points by applying kernel density estimator, and wavelet analysis to identify the main hot regions. Additionally, built environment analysis, and principal component analysis were conducted to verify patterns contributing to crash occurrence in the hotspots. Between 2007 and 2009, 379 crashes were notified, with 466 fatalities on BR277. Higher incidence of crashes occurred on sections of highway with double lanes (ratio 2∶1). The hotspot analysis demonstrated that both the eastern and western regions had higher incidences of crashes when compared to the central region. Through the built environment analysis, we have identified five different patterns, demonstrating that specific environmental characteristics are associated with different types of fatal crashes. Patterns 2 and 4 are constituted mainly by predominantly urban characteristics and have frequent fatal pedestrian crashes. Patterns 1, 3 and 5 display mainly rural characteristics and have higher prevalence of vehicular collisions. In the built environment analysis, the variables length of road in urban area, limited lighting, double lanes roadways, and less auxiliary lanes were associated with a higher incidence of fatal crashes. Conclusions By combining different techniques of analyses, we have identified numerous hotspots and environmental characteristics, which governmental or regulatory agencies could make use to plan strategies to reduce RTI and support life-saving policies.

    Fatal bear attacks on humans are uncommon with only one reported case in Sweden since 1902. The bear population is, however, growing and the frequency of confrontations is likely to increase. Case I-A 40-year-old hunter and his dog were found dead near a bear's den. Autopsy showed that a large portion of the face, facial skeleton, and anterior portion of the brain was missing. Autopsy of the bear showed two nonfatal gunshot wounds. Case II-A 61-year-old man and his dog were found dead outside a hunting lodge. Autopsy revealed numerous wounds, including partial evisceration of the intestines. The victim's blood ethanol concentration was 0.27%. These cases confirm the presence of risk factors identified by the Scandinavian Brown Bear Research Project, that is, provocation by a dog, encountering an injured bear, and appearing close to its den. An additional possible factor in case II was ethanol intoxication.

    Placement of catheters, drains, shunts, and tubes in children can lead to serious or even fatal complications at the moment of placement, such as hemorrhage at insertion, or in the longterm, such as infections and migration into adjacent organs. The clinician should always be aware of these potential complications, especially if the child is unwell. For postmortem diagnostic evaluation, either with a computed tomography scan or an invasive autopsy, all tubes, drains, shunts, and/or catheters should be left in situ. We present three cases with fatal complications after the placement of a chest drain, ventriculoperitoneal shunt, and gastrostomy tube. PMID:28344917

    Cyproheptadine (Periactin) is a first-generation antihistamine available in over-the-counter cold medications and is used to treat allergic-type symptoms. Although antihistamines in general have long been known to cause serious side effects, especially when taken in overdose, few reports that specifically address cyproheptadine-related fatalities exist. A 42-year-old healthy female was found dead at her home with no anatomic cause of death and a recent history of suicidal ideations. Toxicology revealed cyproheptadine and citalopram in the femoral postmortem blood at concentrations of 0.49 and 2.3 mg/L, respectively. Vitreous, urine, and bile analysis were also performed, yielding concentrations of < 0.04 and 0.80 mg/L in the vitreous for cyproheptadine and citalopram, respectively; 0.23 and 8.2 mg/L in the urine; and 30.7 and 9.0 mg/L in the bile. The cause of death was determined to be cyproheptadine and citalopram intoxication, and the manner was ruled a suicide. Although cyproheptadine is widely available in the United States and Europe, there are only two published fatalities due to this antihistamine and only one that specifically cites blood and tissue concentrations. Therefore, this case study will be beneficial to the forensic toxicology community by providing additional information regarding postmortem interpretation.

    The objective of the present study was to identify risk factors among epidemiological factors and meteorological conditions in connection with fatal pulmonary embolism. Information was collected from forensic autopsy records in sudden unexpected death cases where pulmonary embolism was the exact cause of death between 2001 and 2010 in Budapest. Meteorological parameters were detected during the investigated period. Gender, age, manner of death, cause of death, place of death, post-mortem pathomorphological changes and daily meteorological conditions (i.e. daily mean temperature and atmospheric pressure) were examined. We detected that the number of registered pulmonary embolism (No 467, 211 male) follows power law in time regardless of the manner of death. We first described that the number of registered fatal pulmonary embolism up to the nth day can be expressed as Y( n) = α ṡ n β where Y denotes the number of fatal pulmonary embolisms up to the nth day and α > 0 and β > 1 are model parameters. We found that there is a definite link between the cold temperature and the increasing incidence of fatal pulmonary embolism. Cold temperature and the change of air pressure appear to be predisposing factors for fatal pulmonary embolism. Meteorological parameters should have provided additional information about the predisposing factors of thromboembolism.

    Road traffic accidents are responsible for over 3000 deaths per year in the UK, according to Department for Transport (2004a) figures. Although progress is being made in a number of areas, vehicle occupant fatalities have not been falling in line with casualty reduction targets for the year 2010. A sample of 1185 fatal vehicle occupant cases was considered, from ten UK police forces, from the years 1994-2005 inclusive. The main findings were: (1) over 65% of the accidents examined involved driving at excessive speed, a driver in excess of the legal alcohol limit, or the failure to wear a seat belt by a fatality, or some combination of these. (2) Young drivers have the great majority of their accidents by losing control on bends or curves, typically at night in rural areas and/or while driving for 'leisure' purposes. These accidents show high levels of speeding, alcohol involvement and recklessness. (3) Older drivers had fewer accidents, but those fatalities they were involved in tended to involve misjudgement and perceptual errors in 'right of way' collisions, typically in the daytime on rural rather than urban roads. Blameworthy right of way errors were notably high for drivers aged over 65 years, as a proportion of total fatal accidents in that age group.

    In this study a record for comparative international epidemiological studies on autopsy cases of child abuse is introduced. The form was proved in a retrospective comparative survey of cases of fatal child abuse at the Department of Legal Medicine in Kanazawa (Japan) and Institute of Legal Medicine of Lübeck (Germany). A total of 33 cases were included. The following data were evaluated: age and gender of victims and assailants, relationship between victims and assailants, causes and methods of abuse, chief autopsy findings, and causes of death. The results were leading into two directions between Kanazawa and Lübeck: (1) In the years of 1981-1996 in Kanazawa 23 cases of fatal child abuse were autopsied while during the same period in Lübeck only 10 cases were registered. (2) While sexual abuse was not registered in Kanazawa, it was recorded twice in Lübeck.

    Mobile multi-detector computed tomography (MDCT) scanners are potentially available to temporary mortuaries and can be operational within 20 min of arrival. We describe, to our knowledge, the first use of mobile MDCT for a mass fatality incident. A mobile MDCT scanner attended the disaster mortuary after a five vehicle road traffic incident. Five out of six bodies were successfully imaged by MDCT in c. 15 min per body. Subsequent full radiological analysis took c. 1 h per case. The results were compared to the autopsy examinations. We discuss the advantages and disadvantages of imaging with mobile MDCT in relation to mass fatality work, illustrating the body pathway process, and its role in the identification of the pathology, personal effects, and health and safety hazards. We propose that the adoption of a single modality of mobile MDCT could replace the current use of multiple radiological sources within a mass fatality mortuary.

    This commentary addresses the New Zealand study (case report) of a fatal pulmonary embolism (PE) associated with oral contraceptive (OC) use by L. Parkin and colleagues. The study significantly adds to the knowledge on the relationship between fatal PE and OC use, because most of the evidence up to now has related to nonfatal venous thromboembolic events (VTE). Several areas of the study, however, are criticized. These include the method used, definition, and the adjustment of data. However, these criticisms have been offered explanations in this commentary. It is noted that data from the study indicated that OCs containing desogestrel or gestodene are associated with higher risks of fatal PE than are those containing levonorgestrel. This is consistent with most previous studies comparing the effects of second-generation progestogens on VTE. Overall, data support previous pragmatic recommendations that second-generation pills, which contain levonorgestrel, are the combined OCs of choice.

    Many wind-power facilities in the United States have established effective monitoring programs to determine turbine-caused fatality rates of birds and bats, but estimating the number of fatalities of rare species poses special difficulties. The loss of even small numbers of individuals may adversely affect fragile populations, but typically, few (if any) carcasses are observed during monitoring. If monitoring design results in only a small proportion of carcasses detected, then finding zero carcasses may give little assurance that the number of actual fatalities is small. Fatality monitoring at wind-power facilities commonly involves conducting experiments to estimate the probability (g) an individual will be observed, accounting for the possibilities that it falls in an unsearched area, is scavenged prior to detection, or remains undetected even when present. When g < 1, the total carcass count (X) underestimates the total number of fatalities (M). Total counts can be 0 when M is small or when M is large and g < 1. Distinguishing these two cases is critical when estimating fatality of a rare species. Observing no individuals during searches may erroneously be interpreted as evidence of absence. We present an approach that uses Bayes' theorem to construct a posterior distribution for M, i.e., P(M \\ X, ĝ), reflecting the observed carcass count and previously estimated g. From this distribution, we calculate two values important to conservation: the probability that M is below a predetermined limit and the upper bound (M*) of the 100(1 - α)% credible interval for M. We investigate the dependence of M* on α, g, and the prior distribution of M, asking what value of g is required to attain a desired M for a given α. We found that when g < -0.15, M* was clearly influenced by the mean and variance of ĝ and the choice of prior distribution for M, but the influence of these factors is minimal when g > -0.45. Further, we develop extensions for temporal replication that

    Information on foreign-born worker (FBW) and native-born worker (NBW) fatal injuries is scarce. The Kentucky Fatality Assessment and Control Evaluation program analyzed 2001-2014 worker fatality data. The Kentucky FBW fatality rate was double the US FBW and NBW rates, and 50% higher than the Kentucky NBW fatality rate. FBW average age at death was 38 years; NBW age was 47 years. FBW deaths occurred in construction (26%) and services (22%) industries, and transportation [28% (54% due to semi truck crashes)] and construction [26%(48% due to roofing, scaffolding, and ladder-related falls)] occupations; in contrast, NBW deaths occurred in services (22%), and transportation (18%) industries, and transportation (25%) and management (20%) occupations, and were due to exposures to inanimate mechanical forces (38%), and transport accidents (30%). Enhanced FBW cultural competent interventions and policies are needed to prevent FBW occupational injuries, and improve FBW workplace safety and health.

    OSHA revised the 1971 respiratory protection standard in 1998 to add guidance for selecting and maintaining respirators. Fatality reports from 1990 to 2012 were used to characterize historical trends in fatalities associated with respirators. Industry- and time-specific trends were evaluated to determine the effect of the revision to the standard on respirator-related fatalities; 174 respirator-related deaths were reported. The majority of fatalities were associated with using an airline respirator (n = 34) or the absence of using a respirator in required spaces (n = 38). Overall, 79% of fatalities were associated with asphyxia. Fatalities were associated with improper employee use or lack of employer compliance. Reductions in fatality rates over time appeared to be associated with the revisions to the respirator standard, although other variables may influence rates (eg, controls). Recommendations for employers and employees regarding maintaining safe use of respirators are provided.

    Objective: Unpaid work in and around the home is a common and potentially high risk activity, yet there is limited information about the circumstances surrounding resulting injuries. This study aimed to describe circumstances surrounding fatal injuries resulting from home duties activities, in order to identify and prioritise areas for prevention. Design and setting: Coroners' reports on all unintentional deaths in Australia from 1989–92 inclusive were inspected to identify deaths of interest. Rates were calculated using population data and incorporating measures of time engaged in particular home duties activities. Results: There were 296 home duties deaths over the four year period. Most (83%) deaths were of males, and males had 10 times the risk of fatal injury compared with females. The most common activities resulting in fatal injuries were home repairs, gardening, and car care. The highest risk activities (deaths per million persons per year per hour of activity) were home repairs (49), car care (20), home improvements (18), and gardening (16). Being hit by inadequately braced vehicles during car maintenance, falls from inadequately braced ladders, contact with fire and flames while cooking, and contact with electricity during maintenance were the most common injury scenarios. Conclusions: Fatal injury of persons engaged in unpaid domestic work activities is a significant cause of death. Use of activity specific denominator data allows appropriate assessment of the degree of risk associated with each activity. The recurrence of similar circumstances surrounding many independent fatal incidents indicates areas where preventative interventions might be usefully targeted. PMID:12642552

    Background In Malaysia, surveillance of fatal occupational injuries is fragmented. We therefore analyzed an alternative data source from Malaysia’s Social Security organization, the PERKESO. Methods We conducted a secondary data analysis of the PERKESO database comprised of 7 million employees from 2002 to 2006. Results Overall, the average annual incidence was 9.2 fatal occupational injuries per 100,000 workers. During the five-year period, there was a decrease in the absolute number of fatal injuries by 16% and the incidence by 34%. The transportation sector reported the highest incidence of fatal injuries (35.1/100,000), followed by agriculture (30.5/100,000) and construction (19.3/100,000) sectors. Persons of Indian ethnicity were more likely to sustain fatal injuries compared to other ethnic groups. Conclusions Government and industry should develop rigorous strategies to detect hazards in the workplace, especially in sectors that continuously record high injury rates. Targeted interventions emphasizing worker empowerment coupled with systematic monitoring and evaluation is critical to ensure success in prevention and control measures. PMID:22544443

    Compensating wage differentials are used to estimate marginal rates of substitution between income and both fatal and non-fatal occupational-injury risks in the Mexico City metropolitan area. Data are obtained by in-person survey of almost 600 workers and include workers' perceived risks of fatal and non-fatal occupational injury supplemented by actuarial-risk estimates from government statistics. Results using both actuarial- and perceived-risk estimates are reasonably consistent. Estimates of the value per statistical life are between 235,000 US dollars and 325,000 US dollars and estimates of the value per statistical non-fatal injury are between 3500 US dollars and 11,000 US dollars (2002 US dollars). These values are much smaller than corresponding estimates for higher-income countries but are compatible with the small number of prior estimates for lower-income countries.

    Research in child fatalities because of abuse and neglect has continued to increase, yet the mechanisms of the death incident and risk factors for these deaths remain unclear. The purpose of this study was to systematically examine the types of neglect that resulted in children's deaths as determined by child welfare and a child death review board. This case review study reviewed 22 years of data (n=372) of child fatalities attributed solely to neglect taken from a larger sample (N=754) of abuse and neglect death cases spanning the years 1987-2008. The file information reviewed was provided by the Oklahoma Child Death Review Board (CDRB) and the Oklahoma Department of Human Services (DHS) Division of Children and Family Services. Variables of interest were child age, ethnicity, and birth order; parental age and ethnicity; cause of death as determined by child protective services (CPS); and involvement with DHS at the time of the fatal event. Three categories of fatal neglect--supervisory neglect, deprivation of needs, and medical neglect--were identified and analyzed. Results found an overwhelming presence of supervisory neglect in child neglect fatalities and indicated no significant differences between children living in rural and urban settings. Young children and male children comprised the majority of fatalities, and African American and Native American children were over-represented in the sample when compared to the state population. This study underscores the critical need for prevention and educational programming related to appropriate adult supervision and adequate safety measures to prevent a child's death because of neglect.

    A common task in forensic anthropology involves the estimation of the ancestry of a decedent by comparing their skeletal morphology and measurements to skeletons of individuals from known geographic groups. However, the accuracy rates of ancestry estimation methods in actual forensic casework have rarely been studied. This article uses 99 forensic cases with identified skeletal remains to develop accuracy rates for ancestry estimations conducted by forensic anthropologists. The overall rate of correct ancestry estimation from these cases is 90.9%, which is comparable to most research-derived rates and those reported by individual practitioners. Statistical tests showed no significant difference in accuracy rates depending on examiner education level or on the estimated or identified ancestry. More recent cases showed a significantly higher accuracy rate. The incorporation of metric analyses into the ancestry estimate in these cases led to a higher accuracy rate.

    Cyproterone acetate is a steroidal anti-androgen that has been used in human medicine for contraceptive purposes as well as treatment of medical conditions responsive to suppression of testosterone production. While serious side effects are considered to be rare, sporadic cases of severe hepatitis have been reported, including several fatal cases. This report describes a case of fatal fulminant hepatitis in one of four male chimpanzees (Pan troglodytes) that were undergoing trial treatment with cyproterone acetate to decrease inter-male aggression.

    The necropsy records of dairy cows with mastitis were reviewed from the provincial veterinary laboratory in Guelph (44 cases of mastitis in nine years) and from the Ontario Veterinary College (168 cases in 14 years). Mastitis was considered to be the primary cause of death in 167 of 212 cows (79%). Of these 167 cases of mastitis, Escherichia coli was involved in 107 (64%), Klebsiella sp. in 12 (7%) and Staphylococcus aureus in 11 (7%). Bacteriology was not reported in 22 cases. Coliform mastitis, the most commonly identified type of fatal mastitis, was characterized histologically by the presence of infarcted areas in affected glands and by the lack of demonstrable bacteria, and was thus easily identified from fatal mastitis caused by S. aureus.

    Drug abuse with alcohol consumption have been on the rise in Split-Dalmatian County for a while now. This article reports two separate cases with three deaths due to fatal combinations of heroin and alcohol. The first case of poisoning is related to a young couple, a 30-year-old man and a 28-year-old woman, who were found dead in a car, surrounded by cans of a variety alcoholic drinks. Two needles were found beside the bodies as well. The victims were registered drug abusers who had been in withdrawal programs. The second case was a 29-year-old man who was found dead in a house. Three fresh injection marks were visible on his right arm, and two needles were near his body. He was not known as a drug addict, but he had tried to commit suicide recently. Carboxyhaemoglobin was found in blood samples of both victims from the first case. The concentration was 25% and that could contribute to their death. In both described cases blood alcohol concentration was higher then 1.60 g kg(-1). Toxicology tests were positive for heroin, meconin, acetaminophen, 6-acetylmorphine, codeine, noscapine and papaverine. Ethanol, being a respiratory depressant, combined with morphine drastically increases the risk of rapid death due to respiration failure.

    Objective. Clozapine provides a 50%–60% response rate in refractory schizophrenia but has a narrow therapeutic index and is susceptible to pharmacokinetic interactions, particularly with strong inhibitors or inducers of cytochrome P450 (CYP) 1A2. Case Report. We report the case of a 28-year-old nonsmoking female with intellectual disability who was maintained for 3 years on clozapine 100 mg orally twice daily. The patient was treated for presumptive urinary tract infection with ciprofloxacin 500 mg orally twice daily and two days later collapsed and died despite resuscitation efforts. The postmortem femoral clozapine plasma level was dramatically elevated at 2900 ng/mL, and the cause of death was listed as acute clozapine toxicity. Conclusion. Given the potentially fatal pharmacokinetic interaction between clozapine and ciprofloxacin, clinicians are advised to monitor baseline clozapine levels prior to adding strong CYP450 1A2 inhibitors, reduce the clozapine dose by at least two-thirds if adding a 1A2 inhibitor such as ciprofloxacin, check subsequent steady state clozapine levels, and adjust the clozapine dose to maintain levels close to those obtained at baseline.

    Because group-hunting arboreal ants spread-eagle insect prey for a long time before retrieving them, these prey can be coveted by predatory flying insects. Yet, attempting to rob these prey is risky if the ant species is also an effective predator. Here, we show that trying to rob prey from Azteca andreae workers is a fatal error as 268 out of 276 potential cleptobionts (97.1 %) were captured in turn. The ant workers hunt in a group and use the "Velcro®" principle to cling firmly to the leaves of their host tree, permitting them to capture very large prey. Exceptions were one social wasp, plus some Trigona spp. workers and flies that landed directly on the prey and were able to take off immediately when attacked. We conclude that in this situation, previously captured prey attract potential cleptobionts that are captured in turn in most of the cases.

    Naegleria fowleri is a free living parasite which habitats in fresh water reservoirs. It causes a fatal nervous system infection known as primary amoebic meningoencephalitis by invading through cribriform plate of nose and gaining entry into brain. We report a case of primary amoebic meningoencephalitis caused by Naegleria fowleri in Karachi, Pakistan, in a 42 years old male poultry farm worker having no history of swimming. Clinical course was fulminant and death occurred within one week of hospital admission. Naegleria fowleri was detected by wet mount technique in the sample of cerebrospinal fluid collected by lumbar puncture of patient. This is a serious problem and requires immediate steps to prevent general population to get affected by this lethal neurological infection.

    Military parachuting is relatively safe. Most injuries involve vertebral bodies or the lower extremity, and fatalities are rare. We studied 49 military parachute accident facilities occurring during 1964-1989. Causes of the accidents included accidental deployment of reserve parachute in aircraft, static line failures and entanglements, equipment (canopy) failures, in-air collisions, landing injuries, drowning, and dragging. Rarely, preexisting illness such as coronary artery disease caused or contributed to an accident. Pathologic findings revealed a high proportion of deceleration and blunt force injuries: cardiac, aortic and liver laceration, and skull, pelvic and extremity fractures. Isolated head injury, strangulation, and post traumatic pulmonary embolus were occasionally noted. Toxicological examination demonstrated contributing factors such as alcohol intoxication or antihistamine use in a small number of cases. Background investigations, scene inspections, autopsy and toxicology studies all yielded important data or pertinent negatives during investigations. We propose an investigation protocol.

  16. A record number of fatalities in many categories of patients treated with deferasirox: loopholes in regulatory and marketing procedures undermine patient safety and misguide public funds?

    A record 4113 fatalities were reported in 2012 in a postmarketing surveillance of patients treated with deferasirox, despite warnings of life-threatening toxic side effects, and the need for regular monitoring and prophylactic measures. In an EMA report, the mortality rate was estimated at 11.7% and a warning was issued for increasing the dose from 30 to 40 mg/kg/day. In an earlier FDA report of 2474 individual fatality cases, it was revealed that deferasirox was used in many categories of patients. Among the fatal cases reported were many young individuals and about 500 patients with normal iron stores such as cancer, leukaemia, cardiovascular and neurological diseases. The iron-loaded patient categories included myelodysplasia, sickle cell disease, haemochromatosis and thalassaemia. The rate of fatalities and the number of patient categories involved suggest that there has been an indiscriminate and uncontrollable use of deferasirox. These findings raise major concerns on patient safety and question the role, practices and procedures adopted by pharmaceutical companies, regulatory authorities, physicians, etc. in the development of new drugs and their safety. The generic drugs deferiprone, deferoxamine and their combination offer a safer, less expensive and complete treatment of iron overload in thalassaemia and other iron loading conditions.

    Epidemic diphtheria reemerged in the republic of Georgia in November 1993. To identify risk factors for fatal outcomes, clinical and epidemiologic data on all hospitalized diphtheria patients were examined. Medical charts of patients from 1993-1995 were reviewed. A total of 659 cases and 68 deaths were identified (case fatality rate [CFR] = 10.3%). Fifty-two percent of all cases and 68% of deaths were in children 3 days) between onset of symptoms to antitoxin treatment were significantly associated with fatal outcomes. Immunization of children and 40- to 49-year-old adults was required to rapidly control the epidemic.

    In this case report we describe a 67-year-old male, admitted to the ICU with pneumonia who unexpectedly developed a fatal coma due to hyperammonaemia. At postmortem the diagnosis late-onset ornithine transcarbamylase deficiency was made. The non-specific clinical presentation, the rapid deterioration and incidentally the fatal outcome all underline the importance of recognition and knowledge of this genetic disorder. Several measures to treat and prevent potentially fatal episodes of hyperammonaemia are available, if only the disorder is recognised in time. In retrospect, several clues to the diagnosis were available in this fatal case, such as voluntary protein avoidance, as well as several male family members who died at a young age of an unknown cause. After his death, two daughters were discovered to be carriers of an OTC gene mutation, as well as his infant grandson. We emphasise the importance of obtaining ammonia levels in all patients with unexplained coma, seizures or cerebral oedema, irrespective of their age, especially in patients in the ICU or in an otherwise catabolic state.

    This study examines the risk characteristics of fatal motorcycle crashes in Cambodia over a 5-year period (2007-2011). Secondary data analyses were conducted using the Cambodia Road Crash and Victim Information System, the only comprehensive and integrated road crash surveillance system in the country. Researchers from the Centers for Disease Control and Prevention and Handicap International found that (1) males are dying in motorcycle crashes roughly seven times more frequently than females; (2) motorcyclist fatalities increased by about 30% from 2007 to 2011; (3) the motorcyclist death rates per 100,000 population increased from 7.4 to 8.7 deaths from 2007 to 2011; and (4) speed-related crashes and not wearing motorcycle helmet were commonly reported for motorcyclist fatalities at approximately 50% and over 80% through the study years, respectively. Additionally, this study highlights that Cambodia has the highest motorcycle death rate in South-East Asia, far surpassing Thailand, Malaysia, and Myanmar. By recognising the patterns of fatal motorcycle crashes in Cambodia, local road-safety champions and stakeholders can design targeted interventions and preventative measures to improve road safety among motorcyclists.

  20. Driving through the Great Recession: Why does motor vehicle fatality decrease when the economy slows down?

    2016-01-01

    The relationship between short-term macroeconomic growth and temporary mortality increases remains strongest for motor vehicle (MV) crashes. In this paper, I investigate the mechanisms that explain falling MV fatality rates during the recent Great Recession. Using U.S. state-level panel data from 2003–2013, I first estimate the relationship between unemployment and MV fatality rate and then decompose it into risk and exposure factors for different types of MV crashes. Results reveal a significant 2.9 percent decrease in MV fatality rate for each percentage point increase in unemployment rate. This relationship is almost entirely explained by changes in the risk of driving rather than exposure to the amount of driving and is particularly robust for crashes involving large commercial trucks, multiple vehicles, and speeding cars. These findings provide evidence suggesting traffic patterns directly related to economic activity lead to higher risk of MV fatality rates when the economy improves. PMID:26967529

    The most common cause of heat fatalities is environmental exposure during heat waves. Deserts of the southwestern USA are known for temperatures that exceed 32 degrees C for 30 days or more; yet, heat-related fatalities are rare among residents of the region. We compiled data from the National Weather Service and the Office of the Medical Examiner in order to determine the relationship between temperature and occurrence of heat fatalities in Pima County, AZ. Logistic regression indicated that for each degree of increase in temperature (degrees C), there was a 35% increase in the odds of a heat fatality occurring (p<0.001).

    Only carcasses judged to have been killed after the previous search should be included in the fatality data set submitted to this estimator software. This estimator already corrects for carcasses missed in previous searches, so carcasses judged to have been missed at least once should be considered “incidental” and not included in the fatality data set used to estimate fatality. Note: When observed carcass count is <5 (including 0 for species known to be at risk, but not observed), USGS Data Series 881 (http://pubs.usgs.gov/ds/0881/) is recommended for fatality estimation.

    Afatinib is an oral tyrosine kinase inhibitor (TKI) that inhibit Endothelial Growth Factor Receptor (EGFR), Human Epidermal Growth Factor Receptor 2 (HER2), and HER4. The common side effects of EGFR TKI are rash, acne, diarrhea, stomatitis, pruritus, nausea, and loss of appetite. Drug induced pneumonitis is the less common adverse effects of EGFR TKI. Afatinib, 2nd generation EGFR TKI is anticipated to overcome drug resistance from 1st generation EGFR TKI according to preclinical study, and several studies are being conducted to compare clinical efficacy between 1st and 2nd EGFR TKI. Several cases of rug induced acute fatal pneumonitis were reported after use of erlotinib or gefitinib. However, a case of acute fatal pneumonitis associated with afatinib was note reported except drug induced pneumonitis in other clinical study. Here, we present a cases of acute severe pneumonitis related with afatinib in metastatic lung adenocarcinoma with literature review. PMID:27900074

    1985-03-01

    Major mishaps among mobile offshore drilling units worldwide from 1955-1981 were identified from industry and government sources. Based on annual numbers of rigs in service and typical staffing patterns, annual mishap rates and fatality rates for rig types and mishap categories were computed. While the frequency of major mishaps has increased in recent years, the mishap rate per 100 rig-years of service has remained stable. The overall stability obscures the fact that jack-up rigs have had an increasing mishap rate while the rate for other rig types combined has gradually declined. Although the fatal mishap rate has also remained constant, the annual fatality rate per 100 000 full time equivalent (FTE) workers has risen sharply. This can be attributed to increasing numbers of lives lost in environmental mishaps while deaths from operational mishaps have declined. There were 344 fatalities during the 27-year period. Although an average of some 13 deaths per year worldwide appears minimal, the relatively small size of the workforce gives this number significance particularly when it is noted that 'occupational' fatalities, those occurring in the course of routine operations, are not included. The overall fatality rate secondary to major mishaps was 84.3 per 100 000 FTE worker-years.

    To understand the impact of drinking and driving laws on drinking and driving fatality rates, this study explored the different effects these laws have on areas with varying severity rates for drinking and driving. Unlike previous studies, this study employed quantile regression analysis. Empirical results showed that policies based on local conditions must be used to effectively reduce drinking and driving fatality rates; that is, different measures should be adopted to target the specific conditions in various regions. For areas with low fatality rates (low quantiles), people’s habits and attitudes toward alcohol should be emphasized instead of transportation safety laws because “preemptive regulations” are more effective. For areas with high fatality rates (or high quantiles), “ex-post regulations” are more effective, and impact these areas approximately 0.01% to 0.05% more than they do areas with low fatality rates.

    To identify lung findings specific to fatal hypothermia on postmortem computed tomography (CT) imaging. Whole body CT scans were performed followed by full autopsy to investigate causes of death. There were 13 fatal hypothermia cases (group A) and 118 with other causes of death (group B). The chest cavity (CC), dead space including fluid/pneumothorax (DS), aerated lung volume (ALV), percentage aerated lung (%ALV), and tracheal aerated volume (ATV) were measured. Autopsy findings of groups A and B were compared. Receiver operating characteristics (ROC) curves were used to identify factors specific to fatal hypothermia. There were no differences in age, sex, number with emphysema, or time from death to CT examination between the 2 groups. CC, DS, ALV, %ALV, and ATV were 2601.0±247.4 (mL), 281.1±136.5 (mL), 1564.5±281.1 (mL), 62.1±6.2(%), and 21.8±2.7 (mL) in group A and 2339.2±67.7 (mL), 241.1±38.0 (mL), 739.9±67.0 (mL), 31.4±2.3(%), and 15.9±0.8 (mL) in group B, respectively. There were statistically significant differences between groups A and B in ALV, %ALV and ATV. The multiple comparison procedure revealed that ALV and %ALV differed significantly between fatal hypothermia and other causes of death (p<0.05). Using ROC evaluation, %ALV had the largest area under the curve (0.819). This study demonstrates that the %ALV is greater in fatal hypothermia cases than in those with other causes of death on postmortem CT chest imaging. Based on CT, hypothermia is very likely to be the cause of death if the %ALV is >70%.

    Background The purpose of this study was to estimate the incidence of fatal and non-fatal Low Speed Vehicle Run Over (LSVRO) events among children aged 0–15 years in Queensland, Australia, at a population level. Methods Fatal and non-fatal LSVRO events that occurred in children resident in Queensland over eleven calendar years (1999-2009) were identified using ICD codes, text description, word searches and medical notes clarification, obtained from five health related data bases across the continuum of care (pre-hospital to fatality). Data were manually linked. Population data provided by the Australian Bureau of Statistics were used to calculate crude incidence rates for fatal and non-fatal LSVRO events. Results There were 1611 LSVROs between 1999–2009 (IR = 16.87/100,000/annum). Incidence of non-fatal events (IR = 16.60/100,000/annum) was 61.5 times higher than fatal events (IR = 0.27/100,000/annum). LSVRO events were more common in boys (IR = 20.97/100,000/annum) than girls (IR = 12.55/100,000/annum), and among younger children aged 0–4 years (IR = 21.45/100000/annum; 39% or all events) than older children (5–9 years: IR = 16.47/100,000/annum; 10–15 years IR = 13.59/100,000/annum). A total of 896 (56.8%) children were admitted to hospital for 24 hours of more following an LSVRO event (IR = 9.38/100,000/annum). Total LSVROs increased from 1999 (IR = 14.79/100,000) to 2009 (IR = 18.56/100,000), but not significantly. Over the 11 year period, there was a slight (non –significant) increase in fatalities (IR = 0.37-0.42/100,000/annum); a significant decrease in admissions (IR = 12.39–5.36/100,000/annum), and significant increase in non-admissions (IR = 2.02-12.77/100,000/annum). Trends over time differed by age, gender and severity. Conclusion This is the most comprehensive, population-based epidemiological study on fatal and non-fatal LSVRO events to date.

Yet hemorrhage was the third most frequent cause of death from legal abortion in the United States between 1972 and 1979. This study was undertaken to document the scope of the problem, to identify risk factors for fatal hemorrhage and to recommend ways of preventing these deaths. Deaths were identified through the CDC's nationwide surveillance of deaths from abortions; information on numbers and characteristics of women having legal abortions was obtained from CDC and the Alan Guttmacher Institute. Twenty-four women died from hemorrhage after legal abortion in the United States from 1972 to 1979, for a death-to-case rate of 0.3 deaths per 100,000 abortions (95 per cent confidence interval 0.2 to 0.5). Women who died from hemorrhage were significantly older than those who died from other causes (27.6 versus 24.4 years; p less than 0.05). Documented uterine perforation or rupture was far more frequent among women who died from hemorrhage than those who died from other causes (71 versus 8 per cent; p less than 0.001). Women who sustained uterine perforation or rupture were over 1,000 times more likely to die from hemorrhage than those who did not. Deaths from hemorrhage can be eliminated by preventing uterine trauma during abortion and by rapidly diagnosing and treating hemorrhage if it occurs.

    Fatal motor vehicle crashes per capita remained relatively stable over the 1990s, in spite of new traffic safety laws and vehicle innovations. One explanation for this stability is that the price of gasoline declined, which resulted in more vehicle miles traveled and potentially more fatalities. By using 1983-2000 monthly gasoline price and…

    Death from Rocky Mountain spotted fever (RMSF) is preventable with prompt, appropriate treatment. Data from two independent sources were analyzed to estimate the burden of fatal RMSF and identify risk factors for fatal RMSF in the United States during 1999-2007. Despite increased reporting of RMSF cases to the Centers for Disease Control and Prevention, no significant changes in the estimated number of annual fatal RMSF cases were found. American Indians were at higher risk of fatal RMSF relative to whites (relative risk [RR] = 3.9), and children less than 10 years of age (RR=5.1) [corrected] and adults ≥ 70 years of age (RR = 3.0) were also at increased risk relative to other ages. Persons with cases of RMSF with an immunosuppressive condition were at increased risk of death (RR = 4.4). Delaying treatment of RMSF was also associated with increased deaths. These results may indicate a gap between recommendations and practice.

    We report a case of fatal fungal peripheral suppurative thrombophlebitis, caused by Candida albicans, which was disseminated to the blood, lungs, eyes, and spine. Clinical suspicion and aggressive management are important in managing fungal peripheral suppurative thrombophlebitis. Early clinical suspicion is important in managing fungal peripheral suppurative thrombophlebitis, and radical excision of the affected veins, recognition of metastatic foci, and use of systemic antifungal agents are essential to avoid septic shock and death.

    A unique case of a fatal leopard seal attack against an adult human female is presented. The death occurred in Rothera, Antarctica when the female was snorkeling while undertaking scientific research. The principle injuries occurred, during life, to the facial areas prior to the act of drowning. The method of attack of leopard seals against their natural prey is discussed and related to the findings on the deceased.

    Though it has long been known on the basis of clinical associations and serendipitous observation that speech rate is related to mood and psychomotor baseline, it is less known that speech rate is also related to libido and to immune function. We make the case for a bipolar phenomenon of ''psychic tonus,'' encompassing all these dimensions. The…

    Though the statistics on the extent of HIV infection and the number of AIDS cases in Kenya are inaccurate, the World Bank estimates that about 7% of the country's population is infected with HIV. Kisumu, the capital of Western Province, is a small city with one of the highest rates of HIV infection in Kenya. Researchers believe that at least 10% of the city's general population and about 25% of the sexually active are infected with HIV. More than 20% of patients at New Nyanza General Hospital are HIV positive. HIV/AIDS have spread throughout Kenya because most people do not practice safer sex, the majority of infected people do not know that they are infected, a fear of people to obtain condoms, the practice of wife inheritance, and a combination of conservatism, ignorance, and denial about prevailing sexual behavior and the true threat of the epidemic. Although Kenyans have a range of beliefs about the cause of and local treatments for AIDS, they have recently begun to accept HIV for the deadly virus that it is. AIDS is a common cause of death in Kisumu and the villages of the province, but people don't discuss AIDS, and the person with AIDS typically dies at home among family members who do not know what the sickness was. Since no cure has been discovered for AIDS, people need to take the necessary measures to prevent initial infection with HIV.

    Background Dengue is a leading cause of morbidity throughout the tropics; however, accurate population-based estimates of mortality rates are not available. Methods/Principal Findings We established the Enhanced Fatal Acute Febrile Illness Surveillance System (EFASS) to estimate dengue mortality rates in Puerto Rico. Healthcare professionals submitted serum and tissue specimens from patients who died from a dengue-like acute febrile illness, and death certificates were reviewed to identify additional cases. Specimens were tested for markers of dengue virus (DENV) infection by molecular, immunologic, and immunohistochemical methods, and were also tested for West Nile virus, Leptospira spp., and other pathogens based on histopathologic findings. Medical records were reviewed and clinical data abstracted. A total of 311 deaths were identified, of which 58 (19%) were DENV laboratory-positive. Dengue mortality rates were 1.05 per 100,000 population in 2010, 0.16 in 2011 and 0.36 in 2012. Dengue mortality was highest among adults 19–64 years and seniors ≥65 years (1.17 and 1.66 deaths per 100,000, respectively). Other pathogens identified included 34 Leptospira spp. cases and one case of Burkholderia pseudomallei and Neisseria meningitidis. Conclusions/Significance EFASS showed that dengue mortality rates among adults were higher than reported for influenza, and identified a leptospirosis outbreak and index cases of melioidosis and meningitis.

    We analyzed data on non-fatal occupational injuries reported to Malaysia's social security organization from 2002 to 2006. There was a decrease in both the absolute number and the incidence rates of these injuries over time. About 40% of cases occurred in the manufacturing sector followed by the service (17%) and trading (17%) sectors. The agriculture sector reported the highest incidence rate (24.1/1,000), followed by the manufacturing sector subcategories of wood-product manufacturing (22.1/1,000) and non-metallic industries (20.8/1,000). Men age 40 to 59 and persons of Indian ethnicity had a greater tendency to sustain injuries. Government and non-governmental organizations should strive to develop strategies to reduce the occupational injuries targeting vulnerable groups. Enforcement of safety measures will further play an important role to ensure that both employees and employers take special precautions to address workplace hazards.
