Simulate how the effect of exposure on disease occurrence and fatality influences the presence and magnitude of bias in survivor cohorts, motivated by an actual survivor cohort under study. We simulated a cohort of 50,000 subjects exposed to a disease-causing exposure over time and followed forty years, where disease incidence was the outcome of interest. We simulated this 'inception' cohort under different assumptions about the effect of exposure on disease occurrence and fatality after disease occurrence. We then created a corresponding 'survivor' (or 'cross-sectional') cohort, where cohort enrollment took place at a specific date after exposure began in the inception cohort; subjects dying prior to that enrollment date were excluded. The disease of interest caused all deaths in our simulations, but was not always fatal. In the survivor cohort, person-time at risk began before enrollment for all subjects who did not die prior to enrollment. We compared exposure-disease associations in each inception cohort to those in corresponding survivor cohorts to determine how different assumptions impacted bias in the survivor cohorts. All subjects in both inception and survivor cohorts were considered equally susceptible to the effect of exposure in causing disease. We used Cox proportional hazards regression to calculate effect measures. There was no bias in survivor cohort estimates when case fatality among diseased subjects was independent of exposure. This was true even when the disease was highly fatal and more highly exposed subjects were more likely to develop disease and die. Assuming a positive exposure-response in the inception cohort, survivor cohort rate ratios were biased downwards when case fatality was greater with higher exposure. Survivor cohort effect estimates for fatal outcomes are not always biased, although precision can decrease. Copyright © 2015 Elsevier Inc. All rights reserved.

During the period April 1983 to March 1986, lymphoreticular lesions in cattle were surveyed at an Ontario abattoir. Postmortem examination of 171,157 cattle revealed macroscopic lesions in 696 animals (0.4%). The most frequent finding was abscessation of a single lymph node, a finding that was observed in 353 cases (50.7% of animals with lesions/0.2% of total slaughter). Actinobacillary granulomas were present in 252 lymph nodes (36.2%/0.1%). Other specific lesions included mycobacteriosis and mycotic or parasitic lymphadenitis. Cases of nonspecific chronic lymphadenitis or granulomas in lymph nodes, pigmentations, malformations, hyperplasia, and neoplasia were also seen. Abscesses were the most common splenic lesions. One animal had localized lymphangiectasia of the epicardium. ImagesFigure 1., Figure 2., Figure 3., Figure 4., Figure 5., Figure 6. PMID:17423120

Prion strains are defined by their biological properties after transmission to wild-type mice, specifically by their incubation periods and patterns of vacuolar pathology ('lesion profiles'). Preliminary results from transmissions of variant Creutzfeldt-Jakob disease (vCJD) to wild-type mice provided the first compelling evidence for the close similarity of the vCJD agent to the agent causing bovine spongiform encephalopathy (BSE). Complete results from this investigation, including the transmission characteristics of vCJD from brain and peripheral tissues of 10 cases (after primary transmission and subsequent mouse-to-mouse passage), have now been analysed. All 10 vCJD sources resulted in consistent incubation periods and lesion profiles, suggesting that all 10 patients were infected with the same strain of agent. Incubation periods suggested that infectious titres may be subject to regional variation within the brain. Comparison of incubation periods and lesion profiles from transmission of brain and peripheral tissues showed no evidence of tissue-specific modification in the biological properties of the agent. Analysis of the protease-resistant prion protein (PrP(res)) by Western blotting from primary and subsequent passages in mice showed a glycosylation pattern closely resembling that of vCJD in humans, the so-called BSE 'glycoform signature'. Minor variations in PrP(res) fragment size were evident between mouse strains carrying different alleles of the gene encoding PrP both in primary transmissions and on further passages of vCJD brain. Overall, the results closely resembled those of previously reported transmissions of BSE in the same mouse strains, consistent with BSE being the origin of all of these vCJD cases.

A novel avian alphaherpesvirus, preliminarily designated sphenicid alphaherpesvirus 1 (SpAHV-1), has been independently isolated from juvenile Humboldt and African penguins (Spheniscus humboldti and Spheniscus demersus) kept in German zoos suffering from diphtheroid oropharyngitis/laryngotracheitis and necrotizing enteritis (collectively designated as penguin-diphtheria-like disease). High-throughput sequencing was used to determine the complete genome sequences of the first two SpAHV-1 isolates. SpAHV-1 comprises a class D genome with a length of about 164 kbp, a G+C content of 45.6 mol% and encodes 86 predicted ORFs. Taxonomic association of SpAHV-1 to the genus Mardivirus was supported by gene content clustering and phylogenetic analysis of herpesvirus core genes. The presented results imply that SpAHV-1 could be the primary causative agent of penguin-diphtheria-like fatal diseases in banded penguins. These results may serve as a basis for the development of diagnostic tools in order to investigate similar cases of penguin diphtheria in wild and captive penguins.

Full Text Available The authors describe the case of a young Brazilian woman who was treated of ileocolonic Crohn's disease sparing rectum, as confirmed by colonoscopy and histopathological examination. After a 4-year course of sulfasalazine treatment, she presented with skin facial lesions in vespertilio, fever, arthralgias and high titers of anti-ANA and LE cells. A sulfasalazine-induced lupus syndrome was diagnosed, because after sulfasalazine withdrawal and a short course of prednisone, the clinical symptoms disappeared and the laboratory tests returned to normal. Mesalazine 3 g/day was started and the patient remained well for the next 3 years, when she was again admitted with fever, weakness, arthralgias, diplopy, strabismus and hypoaesthesia in both hands and feet, microhematuria, haematic casts, hypocomplementemia and high titers of autoimmune antibodies. A diagnosis of associated systemic lupus erythematosus was made. Although a pulsotherapy with methylprednisolone was started, no improvement was noticed. A cyclophosphamide trial was tried and again no positive results occurred. The patient evolved to severe clinical manifestations of general vasculitis affecting the central and peripheral nervous system and lungs, having a fatal evolution after 2 weeks. Although uncommon, the association of both disease may occur, and the authors call attention to this possibility, making a brief review of literature.
Disorders of fatty acid oxidation are rare but can be fatal. Hypoglycaemia with acidosis is a cardinal feature. Cases may present during early childhood or can be delayed into adolescence or beyond. We present a case of multiple acyl-coenzyme A dehydrogenase deficiency (MADD), an extremely rare disorder of fatty acid oxidation. Our 20-year-old patient presented with cardiovascular collapse, raised anion gap metabolic acidosis and non-ketotic hypoglycaemia. She subsequently developed multi-organ failure and sadly died. She had a previous diagnosis of cyclic vomiting syndrome (CVS) for more than 10 years, warranting frequent hospital admissions. The association between CVS and MADD has been made before though the exact relationship is unclear. All patients with persistent severe CVS should have metabolic investigations to exclude disorders of fatty acid oxidation. In case of non-ketotic hypoglycaemia with acidosis, the patient should be urgently referred to a specialist in metabolic diseases. All practitioners should be aware of these rare disorders as a cause of unexplained acidosis.

The effect of body mass index (BMI) on coronary heart disease (CHD) risk is attenuated when mediators of this risk (such as diabetes, hypertension and hyperlipidaemia) are accounted for. However, there is now evidence of a differential effect of risk factors on fatal and non-fatal CHD events, with markers of inflammation more strongly associated with fatal than non-fatal events. To describe the association with BMI separately for both fatal and non-fatal CHD risk after accounting for classical risk factors and to assess any independent effects of obesity on CHD risk. In the West of Scotland Coronary Prevention Study BMI in 6082 men (mean age 55 years) with hypercholesterolaemia, but no history of diabetes or CVD, was related to the risk of fatal and non-fatal CHD events. After excluding participants with any event in the first 2 years, 1027 non-fatal and 214 fatal CHD events occurred during 14.7 years of follow-up. A minimally adjusted model (age, sex, statin treatment) and a maximally adjusted model (including known CVD risk factors and deprivation) were compared, with BMI 25-27.4 kg/m² as referent. The risk of non-fatal events was similar across all BMI categories in both models. The risk of fatal CHD events was increased in men with BMI 30.0-39.9 kg/m² in both the minimally adjusted model (HR = 1.75 (95% CI 1.12 to 2.74)) and the maximally adjusted model (HR = 1.60 (95% CI 1.02 to 2.53)). These hypothesis generating data suggest that obesity is associated with fatal, but not non-fatal, CHD after accounting for known cardiovascular risk factors and deprivation. Clinical trial registration WOSCOPS was carried out and completed before the requirement for clinical trial registration.
Full Text Available Reporting on adverse events is essential to create a culture of safety, which focuses on protecting doctors and patients from medical errors. We present a fatal case of Streptococcus C pharyngitis in a 56-year-old man. The clinical course and the results of additional diagnostics and autopsy showed that sepsis followed by multiple organ failure was the ultimate cause of death. The clinical course appeared fatal due to a chain of adverse events, including errors made by the physicians caring for the patient for 10 days.
Necrotizing fasciitis was recognized centuries ago by physicians.

Venezuelan equine encephalitis (VEE) is a reemerging, mosquito-borne viral disease of the neotropics that is severely debilitating and sometimes fatal to humans. Periodic epidemics mediated by equine amplification have been recognized since the 1920s, but interepidemic disease is rarely recognized. We report here clinical findings and genetic characterization of 42 cases of endemic VEE detected in Panama from 1961-2004. Recent clusters of cases occurred in Darien (eastern Panama) and Panama provinces (central Panama) near rainforest and swamp habitats. Patients ranged from 10 months to 48 years of age, and the more severe cases with neurological complications, including one fatal infection, were observed in children. The VEE virus strains isolated from these cases all belonged to an enzootic, subtype ID lineage known to circulate among sylvatic vectors and rodent reservoir hosts in Panama and Peru. These findings underscore endemic VEE as an important but usually neglected arboviral disease of Latin America.

Oil palm (Elaeis guineensis Jacq.) is an excellent source of vegetable oil for biodiesel production; however, there are still some limitations for its cultivation in Brazil such as Fatal Yellowing (FY) disease. FY has been studied for many years, but its causal agent has never been determined. In Colombia and nearby countries, it was reported that the causal agent of Fatal Yellowing (Pudrición del Cogollo) is the oomycete Phytophthora palmivora, however, several authors claim that Fatal Yellowing and Pudrición del Cogollo (PC) are different diseases. The major aims of this work were to test, using molecular biology tools, Brazilian oil palm trees for the co-occurrence of the oomycete Phytophthora and FY symptoms, and to characterize the fungal diversity in FY diseased and healthy leaves by next generation sequencing. Investigation with specific primers for the genus Phytophthora showed amplification in only one of the samples. Analysis of the fungal ITS region demonstrated that, at the genus level, different groups predominated in all symptomatic samples, while Pyrenochaetopsis and unclassified fungi predominated in all asymptomatic samples. Our results show that fungal communities were not the same between samples at the same stage of the disease or among all the symptomatic samples. This is the first study that describes the evolution of the microbial community in the course of plant disease and also the first work to use high throughput next generation sequencing to evaluate the fungal community associated with leaves of oil palm trees with and without symptoms of FY.

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. Copyright © 2015 Elsevier Inc. All rights reserved.

To determine whether suboptimal management in hospital could contribute to poor outcome in children admitted with meningococcal disease. Case-control study of childhood deaths from meningococcal disease, comparing hospital care in fatal and non-fatal cases. National statistics and hospital records. 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. 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. 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. 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.

Erlotinib is a Human Epidermal Growth Factor Receptor Type 1/tyrosine kinase (EGFR) inhibitor which is used for non-small-cell lung cancer treatment. Despite that erlotinib is considered to have a favorable safety profile, adverse events such as interstitial lung disease (ILD) were reported in pivotal studies. The authors report the first histologically confirmed case of fatal ILD associated with erlotinib therapy. The medical record of a patient who developed fatal ILD after receiving erlotinib treatment was reviewed to identify the cause of death and other factors potentially contributive to this adverse outcome. A 55-year-old smoker with no evidence of pre-existing interstitial disease developed bilateral ILD and respiratory failure which could be explained only as a toxicity of erlotinib. He had a history of stage IV left upper lobe squamous-cell carcinoma for which he had received three successive regimens of chemotherapy (ifosfamide plus gemcitabine, docetaxel, mitomycin plus navelbine), followed five months later by erlotinib. At initiation of erlotinib treatment there were no radiological signs suggestive of ILD disease or apparent clinical signs of respiratory distress. While the patient completed two months with erlotinib therapy he developed bilateral interstitial infiltrates; despite discontinuation of erlotinib he was admitted with respiratory failure two weeks later. Diagnostic work up for other causes of pneumonitis including infectious diseases, congestive cardiac failure and pulmonary infraction was negative. Empiric treatment with oxygene, corticosteroids and later with cyclophosphamide was ineffective and the patient progressively deteriorated and died. The clinical and post-mortem examination findings are presented and the possible association relationship between erlotinib induced ILD and previous chemotherapy is discussed. Physicians should be alert to the fact that erlotinib related ILD, although infrequent, is potential fatal. The

Hand, foot, and mouth disease associated with enterovirus (EV) infections is a common pediatric pathology that is usually considered as benign. However, neurological complications of varying severity, sometimes fatal, are possible, particularly when EV-A71 is involved. Several Asian countries are regularly affected by large-scale epidemics of EV infections with substantial morbidity and mortality, where early screening and appropriate therapeutic management are a public health challenge. In 2016, Europe experienced an epidemic of unusual magnitude, associated with increasing cases of severe neurological complications in Spain and France, mainly affecting children. Virological diagnosis is based on EV genome detection in peripheral clinical specimens (vesicles or oral ulcerations, throat, nasopharyngeal aspirate, stool) in addition to cerebrospinal fluid and blood. EV-A71 is rarely detected in cerebrospinal fluid, which renders the diagnosis of EV-A71-associated encephalitis challenging. We report the case of a 27-month-old child with hand, foot, and mouth disease turning into rapidly progressive and fatal cardiopulmonary failure associated with EV-A71 infection, in France in 2016. EV infections associated with hand, foot, and mouth disease warrant specific epidemiological surveillance outside the Asian region. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

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...

We report two separate naturally occurring cases of fatal herpesviral disease in Cooper's Hawks (Accipiter cooperii). Gross lesions included splenomegaly and hepatomegaly, with diffuse pale mottling or scattered small white foci. Histologic lesions included splenic and hepatic necrosis associated with eosinophilic intranuclear inclusion bodies characteristic of herpesvirus. In one case, necrosis and inclusions were also noted in bone marrow, thymus, bursa of Fabricius, thyroid gland, parathyroid gland, ceca, and the enteric system. Transmission electron microscopy demonstrated viral particles typical of herpesvirus within hepatocyte nuclei and budding from the nuclear membrane. Herpesviral DNA was amplified via polymerase chain reaction (PCR) of paraffin-embedded liver and spleen, and sequence data were consistent with columbid herpesvirus-1, an alphaherpesvirus of Rock Pigeons (Columba livia). PCR results provide evidence that this disease is transmitted to raptors via Rock Pigeons, most likely through ingestion of Rock Pigeons as prey.

Previously, we identified QIL1 as a subunit of mitochondrial contact site (MICOS) complex and demonstrated a role for QIL1 in MICOS assembly, mitochondrial respiration, and cristae formation critical for mitochondrial architecture (Guarani et al., 2015). Here, we identify QIL1 null alleles in two siblings displaying multiple clinical symptoms of early-onset fatal mitochondrial encephalopathy with liver disease, including defects in respiratory chain function in patient muscle. QIL1 absence in patients' fibroblasts was associated with MICOS disassembly, abnormal cristae, mild cytochrome c oxidase defect, and sensitivity to glucose withdrawal. QIL1 expression rescued cristae defects, and promoted re-accumulation of MICOS subunits to facilitate MICOS assembly. MICOS assembly and cristae morphology were not efficiently rescued by over-expression of other MICOS subunits in patient fibroblasts. Taken together, these data provide the first evidence of altered MICOS assembly linked with a human mitochondrial disease and confirm a central role for QIL1 in stable MICOS complex formation.

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.

Although occupational accidents and work-related diseases have been of interest for a long time, due to lack of proper recording and notification systems the official numbers of occupational accidents and work-related diseases are missing for many countries. Presently, the demand for effectiveness and an interest in the economic aspects of accidents have increased prevention activities at company and country levels. Occupational accident data of selected countries and of World Health Organization regional divisions together with the global burden of disease were used in estimating global occupational accidents and fatal work-related diseases. The trend of global occupational accidents and work-related diseases is presented at region and country levels. The years 1998, 2001, and 2003 are compared in the case of occupational accidents and the years 2000 and 2002 in the case of work-related diseases. The total number of occupational accidents and fatal work-related diseases has increased, but the fatality rates per 100,000 workers have decreased. There were almost 360,000 fatal occupational accidents in 2003 and almost 2 million fatal work-related diseases in 2002. Every day more than 960,000 workers get hurt because of accidents. Each day 5,330 people die because of work-related diseases. Information on occupational accidents and work-related diseases is needed so that countries may understand better the importance of occupational health and safety at country and company level. Especially companies in developing countries are not familiar with occupational safety and health. Statistical data is essential for accident prevention; it is a starting point for the safety work.

The nasopharyngeal-associated lymphoreticular tissues (NALT) found in humans, rodents, and other mammals, contribute to immunity in the nasal sinuses(1-3). The NALT are two parallel bell-shaped structures located in the nasal passages above the hard palate, and are usually considered to be secondary components of the mucosal-associated lymphoid system(4-6). Located within the NALT are discrete compartments of B and T lymphocytes interspersed with antigen-presenting dendritic cells(4,7,8). These cells are surrounded by an epithelial cell layer intercalated with M-cells that are responsible for antigen retrieval from the mucosal surfaces of the air passages(9,10). Naive lymphocytes circulating through the NALT are poised to respond to first encounters with respiratory pathogens(7). While NALT disappear in humans by the age of two years, the Waldeyer's Ring and similarly structured lymphatic organs continue to persist throughout life(6). In contrast to humans, mice retain NALT throughout life, thus providing a convenient animal model for the study of immune responses originating within the nasal sinuses(11). Cultures of single-cell suspensions of NALT are not practical due to low yields of mononuclear cells. However, NALT biology can be examined by ex vivo culturing of the intact organ, and this method has the additional advantage of maintaining the natural tissue structure. For in vivo studies, genetic knockout models presenting defects limited to NALT are not currently available due to a poor understanding of the developmental pathway. For example, while lymphotoxin-α knockout mice have atrophied NALT, the Peyer's patches, peripheral lymph nodes, follicular dendritic cells and other lymphoid tissues are also altered in these genetically manipulated mice(12,13). As an alternative to gene knockout mice, surgical ablation permanently eliminates NALT from the nasal passage without affecting other tissues. The resulting mouse model has been used to establish

Primary Care is the fundamental axis of our health system and obliges us to be consistent with our prescriptions. The non-steroidal anti-inflammatory drugs (NSAIDs) have been associated with increased cardiovascular risk and increased risk of all causes of death, as well as acute myocardial infarction (AMI) in patients with a previous myocardial infarction. Pain and cardiac patient management are 2 basic pillars in our daily activity, and we must know the limitations of NSAIDs in patients with established cardiovascular risk. We present a review of the scientific literature with primary interest in the role of NSAIDs and cardiovascular risk. The objective is to determine the relationship between the consumption of different NSAIDs and the fatal and non-fatal events among patients with known coronary disease. This is a review of the scientific literature with primary interest in the role of NSAIDs and cardiovascular risk. The literature review was conducted in PubMed search engines like Tripdatabase and with certain keywords. Of the 15 original papers found, 9 did not correspond completely to the central focus, so the approach was decided from 6 original articles from the past 5 years, which address the central focus of increased cardiovascular risk found (fatal and non-fatal events) in patients with prior cardiovascular disease or AMI being prescribed NSAIDs for any reason. The risk of fatal/non-fatal events in each of the studies is expressed by the odds ratio (OR)/hazard ratio (HR), defined as the probability of an event occurring. A moderate risk was observed for ibuprofen. It increases the risk of acute coronary syndrome after 5 years of cardiovascular event, especially in the 2nd year (OR 1.63; 95% CI 1.42-1.87). It also increases the risk of stroke (HR 1.23; 95% IC 1.10-1.38). Cyclo-oxygenase-2 inhibitors were the third risk group, after nabumetone and diclofenac. Celecoxib increases risk from the 14th day of treatment (HR 2.3; 95% CI 1.79-3.02), having an OR

Jr(a) is a high-prevalence red cell (RBC) antigen. The clinical significance of anti-Jr(a) is controversial. When hemolytic disease of the fetus and newborn (HDFN) occurred, most reported cases were clinically mild. We report the first case of fatal HDFN due to anti-Jr(a). A 28-year-old Caucasian woman with transfusion history was monitored at the 29th week of pregnancy (G4P1). An ultrasound scan showed fetal cardiomegaly and hepatomegaly. An antibody directed against a high-prevalence antigen was detected, but without conclusive identification. An emergency cesarean section was performed at the 36th week. The newborn was hydropic and showed severe anemia. Death occurred 30 hours after birth. Serologic methods were performed to investigate the mother's RBCs and serum. An in vitro functional cellular assay and semiquantitative measurement of anti-Jr(a) were used to determine the clinical significance of the antibody. Anti-Jr(a) was identified in the serum and Jr(a-) phenotype was confirmed. The anti-Jr(a) titer was 1024, with predominant immunoglobulin (Ig)G1 and minor IgG4 subclasses. The functional cellular assay was consistent with an antibody unlikely to cause HDFN. Semiquantitative measurement of anti-Jr(a) showed a reactivity equivalent to a 25 IU per mL (5 microg/mL) concentration of anti-D, a value associated with a significant risk of HDFN. This is the first documented case of fatal HDFN due to anti-Jr(a). Therefore, we recommend close monitoring of pregnant women with a high-titer anti-Jr(a), especially those with an incompatible transfusion history and/or multiple pregnancies. This case report provides new arguments about the clinical significance of anti-Jr(a) in the transfusion setting.

The aim of this study was to describe the microbiologic agents and pathologic processes in fatal bovine respiratory disease (BRD) of feedlot cattle and to investigate associations between agents and pathologic processes. Ninety feedlot calves diagnosed at necropsy with BRD and 9 control calves without BRD were examined, using immunohistochemical (IHC) staining and histopathologic studies. Mannheimia haemolytica (MH) (peracute, acute, and subacute cases) and Mycoplasma bovis (MB) (subacute, bronchiolar, and chronic cases) were the most common agents identified in fatal BRD cases. Significant associations (P BRD of feedlot cattle.

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-Jkb 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-Jkb with severe clinical symptoms and a fatal outcome. A female patient having the AB, Rh(D)-positive boodtype 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-Jkb 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-Jkb, and they should be ready to treat this disease with active therapeutic interventions.

AIMS: To determine the combined influence of leisure-time physical activity and weekly alcohol intake on the risk of subsequent fatal ischaemic heart disease (IHD) and all-cause mortality. METHODS AND RESULTS: Prospective cohort study of 11 914 Danes aged 20 years or older and without pre......-existing IHD. During approximately 20 years of follow-up, 1242 cases of fatal IHD occurred and 5901 died from all causes. Within both genders, being physically active was associated with lower hazard ratios (HR) of both fatal IHD and all-cause mortality than being physically inactive. Further, weekly alcohol...... had the highest HR of both fatal IHD and all-cause mortality within each category of weekly alcohol intake. Thus, the HR of both fatal IHD and all-cause mortality were low among the physically active who had a moderate alcohol intake. Conclusion Leisure-time physical activity and a moderate weekly...

Estimation of absolute risk of cardiovascular disease (CVD), preferably with population-specific risk charts, has become a cornerstone of CVD primary prevention. Regular recalibration of risk charts may be necessary due to decreasing CVD rates and CVD risk factor levels. The SCORE risk charts for fatal CVD risk assessment were first calibrated for Germany with 1998 risk factor level data and 1999 mortality statistics. We present an update of these risk charts based on the SCORE methodology including estimates of relative risks from SCORE, risk factor levels from the German Health Interview and Examination Survey for Adults 2008-11 (DEGS1) and official mortality statistics from 2012. Competing risks methods were applied and estimates were independently validated. Updated risk charts were calculated based on cholesterol, smoking, systolic blood pressure risk factor levels, sex and 5-year age-groups. The absolute 10-year risk estimates of fatal CVD were lower according to the updated risk charts compared to the first calibration for Germany. In a nationwide sample of 3062 adults aged 40-65 years free of major CVD from DEGS1, the mean 10-year risk of fatal CVD estimated by the updated charts was lower by 29% and the estimated proportion of high risk people (10-year risk > = 5%) by 50% compared to the older risk charts. This recalibration shows a need for regular updates of risk charts according to changes in mortality and risk factor levels in order to sustain the identification of people with a high CVD risk.

A replication-defective variant of feline leukemia virus was molecularly cloned directly from infected tissue and found to induce a rapid and fatal immunodeficiency syndrome in cats. Studies with cloned viruses also showed that subtle mutational changes would convert a minimally pathogenic virus into one that would induce an acute form of immunodeficiency. The data suggest that acutely pathogenic viruses may be selected against by current methods for isolation of the human and simian immunodeficiency viruses.
Full Text Available La enfermedad crónica fatal impacta la vida con transformaciones en términos conductuales y afectivos. Los objetivos de este trabajo fueron: identificar el significado de la vivencia de la enfermedad crónica fatal y percibir el significado del concepto de salud y enfermedad, en una muestra brasileña de portadores de enfermedad crónica fatal. Para esto, se adoptó una posición teórica psicosocial de análisis subjetivo, según el abordaje de las representaciones sociales. En cuanto al método, la investigación fue cualitativa y utilizó estudios de caso en pacientes internados portadores de enfermedades crónicas fatales. Se concluyó que es la enfermedad en sí misma lo que parece ocupar un lugar central y dar sentido a los comportamientos y movilizaciones, y que el concepto de salud queda supeditado al estado de enfermedad.

Advanced age and associated comorbidities are-recognized predictors of life-threatening adverse outcomes, such as opportunistic infection following immunosuppressive therapy. We describe the case of an elderly patient with stricturing colonic Crohn's disease and significant clinical comorbidities, initially controlled with corticosteroid induction followed by infliximab, whose course was complicated by fatal disseminated cryptococcal infection and posterior reversible encephalopathy syndrome. Our patient's case highlights rare, but serious, complications of immunosuppression. In applying modern treatment paradigms to the elderly, the clinician must consider the potential for more pronounced adverse effects in this potentially vulnerable group, maximizing benefit and minimizing harm.

Orthopaedic injury is common in the racing Thoroughbred and is a cause of both economic loss to the industry, as well as being an obvious welfare issue. Fatal injuries sustained during racing are an obvious major concern and it is important that all is done to reduce their frequency. As a consequence of the importance of these causes of horse morbidity and mortality, the Horserace Betting Levy Board in the UK has invested considerable resources into research in recent years in this area in an attempt to decrease the frequency of such injuries. This review summarises current knowledge relating to epidemiological investigations relating to fractures, falling and fatalities in the racing Thoroughbred. Studies identify the importance of track surface conditions, the importance of pre-existing orthopaedic pathology, as well as issues relating to the horse's past training and racing experience as important determinants of both injury and death. Such findings can now be used to develop interventions to reduce racehorse injury and death for the benefit of both the industry and the horse. © 2011 EVJ Ltd.

This study charted 237 fatal cases of bovine respiratory disease (BRD) observed from May 2002 to May 2003 in a single Oklahoma feed yard. Postmortem lung samples were used for agent identification and histopathology. Late in the study, 94 skin samples (ear notches) were tested for Bovine viral diarrhea virus (BVDV) by immunohistochemistry (IHC). Bovine respiratory disease morbidity was 14.7%, and the mortality rate of all causes was 1.3%, with more than half (53.8%) attributed to BRD (0.7% total of all causes). The agents isolated were the following: Mannheimia haemolytica (25.0%), Pasteurella multocida (24.5%), Histophilus somni (10.0%), Arcanobacterium pyogenes (35.0%), Salmonella spp. (0.5%), and Mycoplasma spp. (71.4%). Viruses recovered by cell culture were BVDV-1a noncytopathic (NCP; 2.7%), BVDV-1a cytopathic (CP) vaccine strain (1.8%), BVDV-1b NCP (2.7%), BVDV-2a NCP (3.2%), BVDV-2b CP (0.5%), and Bovine herpesvirus 1 (2.3%). Gel-based polymerase chain reaction (PCR) assays were 4.6% positive for Bovine respiratory syncytial virus and 10.8% positive for Bovine coronavirus. Bovine viral diarrhea virus IHC testing was positive in 5.3% of the animals. The mean values were determined for the treatment data: fatal disease onset (32.65 days), treatment interval (29.15 days), number of antibiotic treatments (2.65), number of different antibiotics (1.89), and day of death (61.81 days). Lesions included the following: 1) duration: acute (21%), subacute (15%), chronic (40.2%), healing (2.8%), normal (18.1%), and autolyzed (2.8%); 2) type of pneumonia: lobar bronchopneumonia (LBP; 27.1%), LBP with pleuritis (49.1%), interstitial pneumonia (5.1%), bronchointerstitial pneumonia (1.4%), septic (0.9%), embolic foci (0.5%), other (2.8%), normal (10.3%), and autolyzed (2.8%); and 3) bronchiolar lesions: bronchiolitis obliterans (39.7%), bronchiolar necrosis (26.6%), bronchiolitis obliterans/bronchiolar necrosis (1.4%), other bronchiolar lesions (6.5%), and bronchiolar lesion

To review the concept of fatalism among African Americans by discussing how religiosity/spirituality may guide them in seeking cancer care in a positive rather than a fatalistic way. Nursing, social science, and medical journals. Using culturally targeted faith-based interventions to educate African Americans about cancer can serve as a strategy to increase cancer knowledge, decrease cancer fatalism, and ultimately increase cancer screening and treatment resulting in cancer activism. Nurses should advocate for faith-based initiatives to help address fatalism in the African American community, and to assist them in developing a more proactive role in cancer screening, treatment, and survivorship.

Anonymous screening of lymphoreticular tissues removed during routine surgery has been applied to estimate the UK population prevalence of asymptomatic vCJD prion infection. The retrospective study of Hilton et al (J Pathol 2004; 203: 733-739) found accumulation of abnormal prion protein in three formalin-fixed appendix specimens. This led to an estimated UK prevalence of vCJD infection of ∼1 in 4000, which remains the key evidence supporting current risk reduction measures to reduce iatrogenic transmission of vCJD prions in the UK. Confirmatory testing of these positives has been hampered by the inability to perform immunoblotting of formalin-fixed tissue. Animal transmission studies offer the potential for 'gold standard' confirmatory testing but are limited by both transmission barrier effects and known effects of fixation on scrapie prion titre in experimental models. Here we report the effects of fixation on brain and lymphoreticular human vCJD prions and comparative bioassay of two of the three prevalence study formalin-fixed, paraffin-embedded (FFPE) appendix specimens using transgenic mice expressing human prion protein (PrP). While transgenic mice expressing human PrP 129M readily reported vCJD prion infection after inoculation with frozen vCJD brain or appendix, and also FFPE vCJD brain, no infectivity was detected in FFPE vCJD spleen. No prion transmission was observed from either of the FFPE appendix specimens. The absence of detectable infectivity in fixed, known positive vCJD lymphoreticular tissue precludes interpreting negative transmissions from vCJD prevalence study appendix specimens. In this context, the Hilton et al study should continue to inform risk assessment pending the outcome of larger-scale studies on discarded surgical tissues and autopsy samples.

The fatal infantile neuromuscular type is the most severe form of glycogen storage disease type IV. We report a case of a 22-day-old female neonate born at 34 weeks gestation with polyhyramnios, fetal hydrops, and severe hypotonia. Placental examination revealed numerous periodic acid schiff (PAS)-positive diastase-resistant polyglucosan bodies in the cytoplasm of extravillous trophoblast predominantly in the placental basal plate. Muscle biopsy and autopsy findings supported a diagnosis of neuromuscular-type glycogen storage disease IV with extensive involvement of skeletal muscle, heart, and liver. The diagnosis was confirmed by molecular genetic testing. We could only find one prior report in the English literature that describes placental pathological changes. Our findings suggest that placental examination can be a useful adjunct for early diagnosis, as placentas are often received for pathological examination shortly after birth and usually before a diagnostic muscle biopsy can be performed. Pathologists need to be aware of characteristic placental features.

Human beings are selectively fatalistic. Some risks appear as "background noise," whereas other, quantitatively identical risks cause enormous concern. This essay explores the reasons for selective fatalism and possible legal responses. Sometimes selective fatalism is a product of distributional issues, as people focus especially on risks that face particular groups; sometimes people adapt their preferences and beliefs so as to reduce concern with risks that they perceive themselves unable to...

Full Text Available Abstract Background Though non-communicable diseases contribute to an increasing share of the disease burden in South Asia, health systems in most rural communities are ill-equipped to deal with chronic illness. This analysis seeks to describe care-seeking behavior among women of reproductive age who died from fatal non-communicable diseases as recorded in northwest rural Bangladesh between 2001 and 2007. Methods This analysis utilized data from a large population-based cohort trial in northwest rural Bangladesh. To conduct verbal autopsies of women who died while under study surveillance, physicians interviewed family members to elicit the biomedical symptoms that the women experienced as well as a narrative of the events leading to deaths. We performed qualitative textual analysis of verbal autopsy narratives for 250 women of reproductive age who died from non-communicable diseases between 2001 and 2007. Results The majority of women (94% sought at least one provider for their illnesses. Approximately 71% of women first visited non-certified providers such as village doctors and traditional healers, while 23% first sought care from medically certified providers. After the first point of care, women appeared to switch to medically certified practitioners when treatment from non-certified providers failed to resolve their illness. Conclusions This study suggests that treatment seeking patterns for non-communicable diseases are affected by many of the sociocultural factors that influence care seeking for pregnancy-related illnesses. Families in northwest rural Bangladesh typically delayed seeking treatment from medically certified providers for NCDs due to the cost of services, distance to facilities, established relationships with non-certified providers, and lack of recognition of the severity of illnesses. Most women did not realize initially that they were suffering from a chronic illness. Since women typically reached medically certified
Full Text Available Abstract Introduction Nocardia cyriacigeorgica bacteraemia has been described in the setting of profound immunodeficiency in only two previous case reports. In both instances, diagnosis was rapidly facilitated by 16S rRNA gene sequencing of blood culture isolates. To the best of our knowledge, we believe that our case is the first presentation of N. cyriacigeorgica bacteraemia associated with acute cytomegalovirus disease in a kidney transplant recipient, which was then followed by severe and fatal pneumonia only seven days later. Case presentation We present the case of a 73-year-old Caucasian woman, a renal transplant recipient, with peripheral vascular disease, hypertension, osteoporosis and vascular dementia who was diagnosed with septicemia and pneumonia. In spite of appropriate anti-microbial therapy for nocardial sepsis, she developed severe pneumonia and acute renal failure. Conclusion This case illustrates a potential for disseminated nocardial infection to produce clinical syndromes that may be indistinguishable from acute cytomegalovirus disease. An atypical presentation (pneumonia and renal failure of a rare disease (nocardial septicemia in the setting of renal transplantation is discussed. This case illustrates that the possibility of severe cytomegalovirus disease should be considered in renal transplanted patients diagnosed with nocardial septicemia who subsequently develop severe sepsis, pneumonia, and renal failure. Molecular diagnosis should readily be available to assist with the prompt diagnosis and treatment of these infections in renal transplant patients.
Full Text Available Fatal familial insomnia (FFI and a genetic form of Creutzfeldt-Jakob disease (CJD178 are clinically different prion disorders linked to the D178N prion protein (PrP mutation. The disease phenotype is determined by the 129 M/V polymorphism on the mutant allele, which is thought to influence D178N PrP misfolding, leading to the formation of distinctive prion strains with specific neurotoxic properties. However, the mechanism by which misfolded variants of mutant PrP cause different diseases is not known. We generated transgenic (Tg mice expressing the mouse PrP homolog of the FFI mutation. These mice synthesize a misfolded form of mutant PrP in their brains and develop a neurological illness with severe sleep disruption, highly reminiscent of FFI and different from that of analogously generated Tg(CJD mice modeling CJD178. No prion infectivity was detectable in Tg(FFI and Tg(CJD brains by bioassay or protein misfolding cyclic amplification, indicating that mutant PrP has disease-encoding properties that do not depend on its ability to propagate its misfolded conformation. Tg(FFI and Tg(CJD neurons have different patterns of intracellular PrP accumulation associated with distinct morphological abnormalities of the endoplasmic reticulum and Golgi, suggesting that mutation-specific alterations of secretory transport may contribute to the disease phenotype.

Kawasaki disease is a systemic vasculitis predominately affecting coronary arteries. Hemophagocytic lymphohistiocytosis can complicate the course of Kawasaki disease. Rare cases of secondary hemophagocytic lymphohistiocytosis occurring during the acute phase of Kawasaki disease have been reported. We report here a 4 month-old girl with diffuse coronary ectasia and secondary hemophagocytic lymphohistiocytosis occurring during the acute phase of incomplete Kawasaki disease. Due to the large overlap in clinical symptoms, the presence of atypical findings for Kawasaki disease should suggest the possible diagnosis of hemophagocytic lymphohistiocytosis in these patients.

The 2013-2016 outbreak of Ebola virus disease (EVD) in West Africa infected >28,000 people, including >11,000 who died, and disrupted social life in the region. We retrospectively studied clinical signs and symptoms and risk factors for fatal outcome among 31 Ebola virus-positive patients admitted to the Ebola Treatment Center in Moyamba District, Sierra Leone. We found a higher rate of bleeding manifestations than reported elsewhere during the outbreak. Significant predictors for death were shorter time from symptom onset to admission, male sex, high viral load on initial laboratory testing, severe pain, diarrhea, bloody feces, and development of other bleeding manifestations during hospitalization. These risk factors for death could be used to identify patients in need of more intensive medical support. The lack of fever in as many as one third of EVD cases may have implications for temperature-screening practices and case definitions.

In rural communities that experience high rates of cardiovascular disease (CVD) morbidity and mortality, family history education may enhance risk awareness and support engagement in healthy behaviors but could also engender fatalism. This study was conducted to assess if the relationship between family history and adherence to healthy lifestyle behaviors is moderated by fatalism. Baseline data were obtained from 1,027 adult participants in the HeartHealth in Rural Kentucky study. Multiple linear regression was used to determine whether fatalism moderated the relationship between high-risk family history of CVD and adherence to healthy lifestyle behaviors, controlling for sociodemographic variables and CVD risk factors. The relationship between family history and healthy behaviors was assessed for subgroups of participants divided according to the upper and lower quartiles of fatalism score. The relationship between high-risk family history of CVD and adherence to healthy behaviors was moderated by fatalism. Among those with the highest quartile of fatalism scores, high-risk family history predicted greater adherence to healthy behaviors, while among those in the lowest quartile, and among those with the middle 50% of fatalism scores, there was no association between family history and healthy behavior scores. Family history education can provide people at increased risk for CVD important information to guide health practices. This may be particularly relevant for those with a high degree of fatalistic thinking. In rural communities with limited health resources, family history education, combined with assessment of fatalism, may support better targeted interventions to enhance engagement in healthy behaviors. © 2014 National Rural Health Association.

Full Text Available Our history is full of myths and topics. Therefore the image of femme fatale is frequent in the works of all periods and places. The author of this article first analyzes how the history and literature consistently showed and defined these women, and then presents examples that come from ancient Greece. The art is powered by their power of seduction and the article explains how this femme fatale appeared in literature and film. The article concludes with a brief overview of various arguments concerning women and feminism, present in the literary criticism.

White-nose syndrome (WNS) is a fatal disease of bats that hibernate. The etiologic agent of WNS is the fungus Geomyces destructans, which infects the skin and wing membranes. Over 1 million bats in six species in eastern North America have died from WNS since 2006, and as a result several species of bats may become endangered or extinct. Information is lacking on the pathogenesis of G. destructans and WNS, WNS transmission and maintenance, individual and site factors that contribute to the probability of an outbreak of WNS, and spatial dynamics of WNS spread in North America. We considered how descriptive and analytical epidemiology could be used to fill these information gaps, including a four-step (modified) outbreak investigation, application of a set of criteria (Hill's) for assessing causation, compartment models of disease dynamics, and spatial modeling. We cataloged and critiqued adaptive-management options that have been either previously proposed for WNS or were helpful in addressing other emerging diseases of wild animals. These include an ongoing program of prospective surveillance of bats and hibernacula for WNS, treatment of individual bats, increasing population resistance to WNS (through vaccines, immunomodulators, or other methods), improving probability of survival from starvation and dehydration associated with WNS, modifying hibernacula environments to eliminate G. destructans, culling individuals or populations, controlling anthropogenic spread of WNS, conserving genetic diversity of bats, and educating the public about bats and bat conservation issues associated with WNS.

Full Text Available The author sketches the historical background, then the teaching of the Koran, and finally, the development of the typical Islamic fatalism. The fatalism of Islam has to be viewed against the background of the ideas of pre-Islamic Arabia. Unfortunately, there is no other evidence from this epoch that a few poems on a very restricted range of topics which have been able to survive Islamic censure. The conventional and stereotyped character of these poems makes it difficult to decide to what extent they reflect commonly accepted views or the ideas of a certain group. In any case, they present a picture of the pagan Arab which is extremely idealized and formed after a rigid pattern. Historically speaking, Islamic 'fatalism' is the result of a combination of pre-Islamic fatalism and Muhammad's belief in God's omnipotence. From another point of view it is an interpretation of destiny that expresses man's feeling of total dependence, not on an impersonal power or universal order, but on an omnipotent God.
Full Text Available Although most cytomegalovirus (CMV infections are asymptomatic or cause only mild disease, the virus can cause serious disease and even mortality in immunocompromised children. In patients with WiskottAldrich syndrome (WAS, recurrent CMV infection is infrequently seen. A 3-month-old male infant was referred to Chang Gung Children's Hospital due to persistent thrombocytopenia and intermittent tachypnea. WAS complicated with CMV pneumonitis was diagnosed subsequently. He was discharged at the age of 7 months after a complete course of antiviral treatment. Unfortunately, refractory hemorrhagic gastritis developed later and recurred in spite of antiviral treatment and intravenous immunoglobulin. The patient died of recurrent gastrointestinal bleeding at the age of 23 months. This observation indicates that a case of WAS complicated with CMV gastrointestinal disease may need more vigorous treatment.

The Ebola Virus Disease is a contagious and highly fatal illness that up until recently had been geographically limited to remote areas of Africa. In 2014, Ebola patients have been transported to the United States for care or have been newly diagnosed in the United States. With the intensive medical care and isolation policies usually needed by these patients, we inquired whether pastoral care would be possible. Using clinical and canonical considerations, we analyzed the permissibility and logistical challenges pastoral care presents to the priests and lay ministers, as well as the healthcare system. We conclude that with the approval of local, state, and federal health officials, pastoral care, including provision of the sacraments, is possible. It would require proper training, proper equipment and policies, and a significant commitment of time. While the risk to the pastoral team is difficult to define, it seems low in an Ebola-capable medical system. These risks to priests and ministers seem reasonable given the inestimable benefits of receiving the sacraments during critical illness. Lay summary: Traditional pastoral visits to hospitalized patients might prove difficult or impossible for diseases that are contagious and highly fatal. This inquiry examines the feasibility, challenges, and logistical solutions to these visits. With input from bishops, priests, a canon lawyer, an epidemiologist, a physician, the CDC, and others, we conclude that pastoral visits are possible. Visits will require permission of health authorities, commitments of time, training, and a small but significant risk to the health of priests and others who volunteer for this ministry.

We report a case of an elderly demented woman who died of a mitral rheumatic valvular disease in the context of multiple injuries and from elder abuse. History from police investigation indicated that the deceased was found collapsed on the floor in her bedroom for several days prior to death by her son who did not initiate medical care. Autopsy revealed a frail elderly woman with Alzheimer's disease and evidence of multiple healing sublethal blunt impact injuries of the face, mouth, neck, upper chest, and extremities. In addition, there was unwashed dirt encrusted skin, urine/fecal staining of skin and clothing, dirty overgrown toenails, and matting of the hair. This constellation of findings supports the medical diagnosis of elder abuse with neglect. However, the immediate cause of death was the left-sided congestive heart failure from mitral rheumatic valvular disease. Although the underlying cause of death was related to the chronic cardiac condition, the physical abuse and neglect was considered significant contributing factors to death, since physiologically the injuries and lack of medical treatment was thought to have hastened death by exacerbating the underlying heart disease. This case underscores the need for the forensic pathologist to consider contextual variables and sublethal injuries in cases were the causal interpretations benefit from a more holistic approach. Otherwise, cases like such as the one reported can go unnoticed and certified as a simple natural death.

Exacerbation of chronic obstructive pulmonary disease (COPD) is a disease pattern frequently seen in emergency medical services and intensive care units. Usually, exacerbations of COPD are of infectious origin, and an acute vital threat may take several days to develop. Tension pneumothorax in patients with COPD is a rare and often unexpected cause of acute vital threat. To the best of our knowledge, this is a unique case of CO2 narcosis after spontaneous tension pneumothorax in a patient with COPD. We describe the rapid development of respiratory insufficiency and near fatal pulmonary failure in a 65-year-old female patient with COPD due to spontaneous tension pneumothorax. The patient was in respiratory failure and comatose upon arrival of the emergency service. Before mechanical ventilation, coma could be confirmed to be due to CO2 narcosis caused by exorbitant arterial hypercapnia (PCO2, 193 mm Hg). Pneumothorax was diagnosed in the hospital by chest x-ray and resolved after pleural drainage. The patient could be extubated early and discharged without sequelae. In conclusion, we want to report the occurrence of a tension pneumothorax as an important and potentially overseen condition in patients with COPD with acute respiratory failure.

The current outbreak of Ebola virus disease (EVD) in West Africa has infected more than 28,000 people, killed more than 11,000 and disrupted social life. We studied retrospectively the clinical presentation and risk factors for fatal outcome among the 31 Ebola virus (EBV) positive patients admitted to the Ebola Treatment Center (ETC) in Moyamba District, Sierra Leone. We found a higher rate of bleeding manifestations than reported elsewhere during the current outbreak. Significant predictors for fatal outcome were shorter time from onset to admission, male sex, high viral load on initial lab test, severe pain, diarrhea, bloody stools, and development of other bleeding manifestations during hospital admission. Awareness of risk factors for fatal outcome could be used to identify patients in need of more intensive medical support. The lack of fever in as much as a third of EVD cases may have implications for temperature screening practices and case definitions.

Klebsiella is a Gram-negative bacterium that causes different types of health care-associated infections including pneumonia, bloodstream infections, surgical site infections and meningitis. We report here a case of Klebsiella pneumoniae meningitis in a patient with diabetes mellitus and Hansen's disease. A middle-aged man with a known case of diabetes mellitus and Hansen's disease presented with the complaints of blurred vision in the left eye and the patient was found to have cataract. Patient was operated for cataract and Intraocular lens implanted. Patient developed headache and vomiting on the 4th post-operative day. Lumbar puncture was carried out and gram stain of cerebrospinal fluid showed Gram-negative bacilli in the direct smear and culture yielded a heavy growth of K. pneumoniae. The patient was treated with antimicrobials according to the susceptibility pattern. He initially showed improvement but later on developed altered sensorium and hypotension. Patient succumbed to infection in spite of all medical attention.

Human prion diseases are rare fatal neurodegenerative conditions that occur as acquired, familial, or idiopathic disorders. A key event in their pathogenesis is the accumulation of an altered form of the prion protein, termed PrPSc, in the central nervous system. A novel acquired human prion disease, variant Creutzfeldt-Jakob disease, is thought to result from oral exposure to the bovine spongiform encephalopathy agent. This disease differs from other human prion diseases in its neurological, neuropathological, and biochemical phenotype. We have used immunohistochemistry and Western blot techniques to analyze the tissue distribution and biochemical properties of PrPSc in peripheral tissues in a unique series of nine cases of variant Creutzfeldt-Jakob disease. We have compared this with the distribution and biochemical forms found in all of the major subtypes of sporadic Creutzfeldt-Jakob disease and in a case of iatrogenic Creutzfeldt-Jakob disease associated with growth hormone therapy. The results show that involvement of the lymphoreticular system is a defining feature of variant Creutzfeldt-Jakob disease, but that the biochemical isoform of PrPSc found is influenced by the cell type in which it accumulates.

Prions are normal proteins present in all mammals, especially in the central nervous system (CNS) and lymphoreticular tissue. Their transformation into a highly infectious molecule gives rise to a group of diseases known as transmissible spongiform encephalopathies (TSEs), which cause vacuolar degeneration of gray matter and produce a fatal neurodegenerative disorder. Prion diseases have attracted considerable attention in recent years, and this review of the literature was designed to determine their implications for dentistry, studying the possibility of cross-transmission in the dental office and describing their oral manifestations. The main oral manifestations are dysphagia, dysarthria, paresthesias, dysesthesias, and dysgeusia. The most frequently involved oral tissues are the trigeminal ganglion, posterior third of the tongue, tonsils, and, much less commonly, alveolar nerves, gingiva, and salivary glands. Although no contagion has been reported in the dental setting to date, prions resist the usual dental sterilization systems and transmission of this type of disease remains a potential risk. It is therefore important for dentists to be aware of these diseases, to identify high-risk patients by obtaining an adequate clinical history, and to know the appropriate procedures to be followed.

In the past 17 years, neurological disease associated with enterovirus A71 (EV-A71) has increased dramatically in the Asia-Pacific region with a high fatality rate in young infants, often due to pulmonary oedema, however the mechanism of this oedema remains obscure. We analysed the brainstem, heart and lungs of 15 fatal cases of confirmed EV-A71 infection in order to understand the pathophysiological mechanism of death and pulmonary oedema. In keeping with other case studies, the main cause of death was neurogenic pulmonary oedema. In the brainstem, 11 cases showed inflammation and all cases showed parenchymal inflammation with seven cases showing moderate or severe clasmatodendrosis. No viral antigen was detected in sections of the brainstem in any of the cases. All fatal cases showed evidence of pulmonary oedema; however, there was absence of direct pulmonary viral damage or myocarditis-induced damage and EV-A71 viral antigen staining was negative. Though there was no increase in staining for Na/K-ATPase, 11 of the 15 cases showed a marked reduction in aquaporin-4 staining in the lung, and this reduction may contribute to the development of fatal pulmonary oedema.

Full Text Available 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.

To describe the relationship between two measures of body fat and selected non-fatal health conditions in the New Zealand adult population in 2003. Data were obtained from the 2002/03 New Zealand Health Survey. A total of 10,026 adults aged 25 years and over were classified according to measured body mass index (BMI) and waist circumference (WC). BMI classes were 18.5-24.9, 25.0-29.9, 30.0-34.9, > or = 35.0 kg/m2. WC classes were 102 centimetres (cm) for males and 88 cm for females. Prevalence rate ratio estimates for selected self-reported health conditions were calculated for males and females separately, adjusting for age, ethnicity, deprivation and smoking using logistic regression. Increasing BMI or WC class was associated with increasing prevalence of cardiovascular disease, diabetes, high blood pressure, high blood cholesterol, osteoarthritis, asthma and sleep disorders in both males and females. The association with depression was not statistically significant in either gender. Associations were strongest for diabetes and blood pressure, with adults in the highest BMI or WC class at least 3.5 times more likely to have diabetes and 2-3 times more likely to have high blood pressure compared with those in the lowest classes. Increasing body fatness, defined by either BMI or WC, was associated with increased prevalence of many important health conditions. If the obesity epidemic is not halted or reversed, the impact on both the New Zealand population and health system will be considerable.

Healthcare legislation in European countries is similar in many respects. Most importantly, the framework of informed consent determines that physicians have the duty to provide detailed information about available therapeutic options and that patients have the right to refuse measures that contradict their personal values. However, when it comes to end-of-life decision-making a number of differences exist in the more specific regulations of individual countries. These differences and how they might nevertheless impact patient's choices will be addressed in the current debate. In this article we show how the legal and medical frameworks of Germany, Poland and Sweden differ with regard to end-of-life decisions for patients with a fatal progressive disease. Taking Amyotrophic Lateral Sclerosis (ALS) as an example, we systematically compare clinical guidelines and healthcare law, pointing out the country-specific differences most relevant for existential decision-making. A fictional case report discusses the implications of these differences for a patient with ALS living in either of the three countries. Patients with ALS in Germany, Poland and Sweden are confronted with a similar spectrum of treatment options. However, the analysis of the normative frameworks shows that the conditions for making existential decisions differ considerably in Germany, Poland and Sweden. Specifically, these differences concern (1) the legal status of advance directives, (2) the conditions under which life-sustaining therapies are started or withheld, and (3) the legal regulations on assisted dying. According to the presented data, regulations of terminating life-sustaining treatments and the framework of "informed consent" are quite differently understood and implemented in the legal setting of the three countries. It is possible, and even likely, that these differences in the legal and medical frameworks have a considerable influence on existential decisions of patients with ALS.
Jane Austen is typically described as having excellent health until the age of 40 and the onset of a mysterious and fatal illness, initially identified by Sir Zachary Cope in 1964 as Addison's disease. Her biographers, deceived both by Cassandra Austen's destruction of letters containing medical detail, and the cheerful high spirits of the existing letters, have seriously underestimated the extent to which illness affected Austen's life. A medical history reveals that she was particularly susceptible to infection, and suffered unusually severe infective illnesses, as well as a chronic conjunctivitis that impeded her ability to write. There is evidence that Austen was already suffering from an immune deficiency and fatal lymphoma in January 1813, when her second and most popular novel, Pride and Prejudice, was published. Four more novels would follow, written or revised in the shadow of her increasing illness and debility. Whilst it is impossible now to conclusively establish the cause of her death, the existing medical evidence tends to exclude Addison's disease, and suggests there is a high possibility that Jane Austen's fatal illness was Hodgkin's disease, a form of lymphoma.

The effect of the tritiated thymidine ( 3 H-TdR) suicide technique on the ability of donor cells to induce fatal graft-versus-host disease (GVHD) was studied. C57BL/6 (H-2/sup b/) spleen cells were stimulated in vitro with irradiated BALB/c (H-2/sup d/) Moloney lymphoma cells in mixed culture and 3 H-TdR of high-specific activity added to eliminate proliferating cells. The ability of such cells to induce fatal GVHD was assayed by injecting them i.v. into adult BALB/c mice immunosuppressed with cyclophosphamide (180 mg/kg). These cells induced fatal GVHD in fewer mice (52 percent) than did C57BL/6 cells cultured with BALB/c lymphoma cells but without 3 H-TdR (87 percent) and C57BL/6 cells cultured with irradiated C57BL/6 cells with (95 percent) or without 3 H-TdR (86 percent). Thus, the 3 H-TdR suicide technique greatly diminished the ability of cells to induce lethal GVHD

Fatalism has been a central framework for understanding the psychological processes in cultures with pronounced collectivism that are economically poorly developed. In this context, fatalism emerges as cognitive schema defined by passive and submissive acceptance of an irremediable destiny, governed by some natural force or the will of some God. This image has now lost such a clear profile. But currently, fatalism also accompanies the life of people from individualist cultures, who live in a highly developed, or even opulent, economic context. In this case, fatalism is like some mood of uncertainty, insecurity, and helplessness following the events that characterize the society of global risk. In this paper, we propose a theory to develop the two faces of fatalism.
The Rajiv Gandhi Foundation (RGF), together with the AIMS-affiliated NGO AIDS Cell, Delhi, held a workshop as part of an effort to raise a 90-doctor RGF AIDS workforce which will work together with nongovernmental organizations on AIDS prevention, control, and management. 25 general practitioners registered with the Indian Medical Council, who have practiced medicine in Delhi for the past 10-20 years, responded to a pre-program questionnaire on HIV-related knowledge and attitudes. 6 out of the 25 physicians did not know what the acronym AIDS stands for, extremely low awareness of the clinical aspects of the disease was revealed, 9 believed in the conspiracy theory of HIV development and accidental release by the US Central Intelligence Agency, 8 believed that AIDS is a problem of only the promiscuous, 18 did not know that the mode of HIV transmission is similar to that of the hepatitis B virus, 12 were unaware that HIV-infected people will test HIV-seronegative during the first three months after initial infection and that they will develop symptoms of full-blown AIDS only after 10 years, 10 did not know the name of even one drug used to treat the disease, 3 believed aspirin to be an effective drug against AIDS, many believed fantastic theories about the modes of HIV transmission, and many were acutely homophobic. Efforts were made to clear misconceptions about HIV during the workshop. It is hoped that participating doctors' attitudes about AIDS and the high-risk groups affected by it were also improved.

Full Text Available The gastrointestinal (GI tract plays a central role in the pathogenesis of transmissible spongiform encephalopathies. These are human and animal diseases that include bovine spongiform encephalopathy, scrapie and Creutzfeldt-Jakob disease. They are uniformly fatal neurological diseases, which are characterized by ataxia and vacuolation in the central nervous system. Alhough they are known to be caused by the conversion of normal cellular prion protein to its infectious conformational isoform (PrPsc the process by which this isoform is propagated and transported to the brain remains poorly understood. M cells, dendritic cells and possibly enteroendocrine cells are important in the movement of infectious prions across the GI epithelium. From there, PrPsc propagation requires B lymphocytes, dendritic cells and follicular dendritic cells of Peyer’s patches. The early accumulation of the disease-causing agent in the plexuses of the enteric nervous system supports the contention that the autonomic nervous system is important in disease transmission. This is further supported by the presence of PrPsc in the ganglia of the parasympathetic and sympathetic nerves that innervate the GI tract. Additionally, the lymphoreticular system has been implicated as the route of transmission from the gut to the brain. Although normal cellular prion protein is found in the enteric nervous system, its role has not been characterized. Further research is required to understand how the cellular components of the gut wall interact to propagate and transmit infectious prions to develop potential therapies that may prevent the progression of transmissible spongiform encephalopathies.

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.

The 2013–2016 outbreak of Ebola virus disease (EVD) in West Africa infected >28,000 people, including >11,000 who died, and disrupted social life in the region. We retrospectively studied clinical signs and symptoms and risk factors for fatal outcome among 31 Ebola virus–positive patients admitted to the Ebola Treatment Center in Moyamba District, Sierra Leone. We found a higher rate of bleeding manifestations than reported elsewhere during the outbreak. Significant predictors for death were shorter time from symptom onset to admission, male sex, high viral load on initial laboratory testing, severe pain, diarrhea, bloody feces, and development of other bleeding manifestations during hospitalization. These risk factors for death could be used to identify patients in need of more intensive medical support. The lack of fever in as many as one third of EVD cases may have implications for temperature-screening practices and case definitions. PMID:27268303

Vogt-Koyanagi-Harada (VKH) disease is a primary autoimmune stromal choroiditis. Aim of the study was to gather a body of evidence from the literature and from experts that systemic corticosteroid combined with non-steroidal immunosuppressive therapy should become the standard of care in initial-onset VKH disease. Literature was reviewed and leading experts in VKH were consulted in different parts of the world in order to put forward a consensus attitude in the management of initial-onset VKH disease. There was a substantial body of evidence in the literature that early aggressive and sustained corticosteroid and non-steroidal immunosuppressive therapy in initial-onset VKH disease allows to achieve full control of choroidal inflammation, eliminating any subclinical choroidal inflammation, and substantially reduces recurrences with improvement of anatomical and functional outcomes. This was in agreement with experts' opinion and practice. ICGA was the method of choice to monitor disease evolution. Since the choroidal space is easily accessible to systemic therapy and because inflammation in VKH disease is exclusively originating from the choroidal stroma, early and sustained treatment right at the onset of the disease process with dual corticosteroid and non-steroidal immunosuppressive therapy can result in full "healing" in many cases preventing sunset glow fundus which results from depigmentation from chronic uncontrolled inflammation.

We examine the impact of fatalism, the belief that one has little or no control over future events, on the decision of whether or not to save. We develop a model that predicts that fatalism decreases savings for moderately risk averse individuals, increases savings for highly risk averse individuals, and otherwise has no impact. Furthermore, fatalism decreases effort in learning about savings and investment options. We use data from National Longitudinal Survey of Youth (NLSY) and find genera...

Sickle cell disease (SCD) manifests itself with vaso-occlusive episodes leading to infarction. Placement of intravascular catheters provides a useful route for management of pain crises as well as other complications. However, catheter misuse is a commonly unrecognized problem, which can have lethal consequences. We present a case of fatal splenic sequestration/hyperhemolysis secondary to foreign body pulmonary and systemic embolization due to intravenous administration of hydromorphone pills in a young woman with SCD. Morphological identification of the embolized particles (crospovidone, microcrystalline cellulose, and hydrophilic polymer) was key in understanding the mechanism of death. Foreign particle deposition induced a granulomatous inflammatory response that resulted in obliteration and distortion of the microvasculature, thus triggering sickling with subsequent organ damage. Despite clinical evidence of asplenia and microscopic white pulp fibrosis with Gamna-Gandy body formation, unexpectedly for the patient's age, the spleen was enlarged by entrapped sickle cells. The findings support the possibility that loss of function can coexist with increased splenic activity under certain circumstances, an overlooked clinical phenotype of SCD. This case illustrates the teaching value of classic autopsy in addition to its crucial role in understanding the natural history of complex heterogeneous diseases.

Prenatal development is recognized as a critical period in the etiology of obesity and cardiometabolic disease. Potential strategies to reduce maternal obesity-induced risk later in life have been largely overlooked. In this paper, we first propose a conceptual framework for the role of public health and preventive medicine in mitigating the effects of fetal programming. Second, we review a small but growing body of research (through August 2015) that examines interactive effects of maternal ...
Full Text Available Abstract Background Primary angiitis of the central nervous system is an idiopathic disorder characterized by vasculitis within the dural confines. The clinical presentation shows a wide variation and the course and the duration of disease are heterogeneous. This rare but treatable disease provides a diagnostic challenge owing to the lack of pathognomonic tests and the necessity of a histological confirmation. Case presentation A 28-year-old patient presenting with headache and fluctuating signs of encephalopathy was treated on the assumption of viral meningoencephalitis. The course of the disease led to his death 10 days after hospital admission. Postmortem examination revealed primary angiitis of the central nervous system. Conclusion Primary angiitis of the central nervous system should always be taken into consideration when suspected infectious inflammation of the central nervous system does not respond to treatment adequately. In order to confirm the diagnosis with the consequence of a modified therapy angiography and combined leptomeningeal and brain biopsy should be considered immediately.

Prenatal development is recognized as a critical period in the etiology of obesity and cardiometabolic disease. Potential strategies to reduce maternal obesity-induced risk later in life have been largely overlooked. In this paper, we first propose a conceptual framework for the role of public health and preventive medicine in mitigating the effects of fetal programming. Second, we review a small but growing body of research (through August 2015) that examines interactive effects of maternal obesity and two public health foci - diet and physical activity - in the offspring. Results of the review support the hypothesis that diet and physical activity after early life can attenuate disease susceptibility induced by maternal obesity, but human evidence is scant. Based on the review, we identify major gaps relevant for prevention research, such as characterizing the type and dose response of dietary and physical activity exposures that modify the adverse effects of maternal obesity in the offspring. Third, we discuss potential implications of interactions between maternal obesity and postnatal dietary and physical activity exposures for interventions to mitigate maternal obesity-induced risk among children. Our conceptual framework, evidence review, and future research directions offer a platform to develop, test, and implement fetal programming mitigation strategies for the current and future generations of children.

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.
Full Text Available Adult-onset Still′s disease (AOSD is a rare inflammatory disorder of unknown etiology characterized by fever, evanescent pink salmon rash, arthritis, and multiorgan involvement. Here, we report an unusual manifestation of AOSD in a 40-year-old male who presented to our hospital with pyrexia of unknown origin and rash of 3 weeks duration. All his serological investigations and imaging studies were unremarkable. He was fulfilling clinical and laboratory criteria as per Yamaguchi for AOSD and was managed for the same. Our patient did not respond well to the treatment, had a downhill course, and succumbed to his illness. Autopsy confirmed myocarditis and florid bone marrow reactive hemophagocytosis as the cause of his death.

An 85-year-old man with dementia first visited our hospital 5 years ago, complaining of hemoptysis. He was hospitalized 2 years later owing to fever, cough, and dyspnea. A chest computed tomography scan showed infiltration with a cavity in the left upper lobe. He was diagnosed with nontuberculous mycobacterial lung infection on the basis of the presence of acid-fast bacilli in the sputum and repeated bronchoalveolar lavage specimens; however, we were unable to identify the isolate by DNA-DNA hybridization. Although his general condition had slightly improved after treatment initiation, intermittent chemotherapy owing to the adverse effects of the drugs and dementia led to rapid disease progression and death. After his death, the isolated mycobacterium was identified as Mycobacterium kyorinense by sequence analysis of the hsp 65 and rpoB genes.

Respiratory infections are important causes of morbidity and mortality in reptiles; however, the causative agents are only infrequently identified. Pneumonia, tracheitis and esophagitis were reported in a collection of ball pythons (Python regius). Eight of 12 snakes had evidence of bacterial pneumonia. High-throughput sequencing of total extracted nucleic acids from lung, esophagus and spleen revealed a novel nidovirus. PCR indicated the presence of viral RNA in lung, trachea, esophagus, liver, and spleen. In situ hybridization confirmed the presence of intracellular, intracytoplasmic viral nucleic acids in the lungs of infected snakes. Phylogenetic analysis based on a 1,136 amino acid segment of the polyprotein suggests that this virus may represent a new species in the subfamily Torovirinae. This report of a novel nidovirus in ball pythons may provide insight into the pathogenesis of respiratory disease in this species and enhances our knowledge of the diversity of nidoviruses.

Calciphylaxis is a potentially fatal complication of persistent secondary hyperparathyroidism; its cause is still not clear. Unfortunately there is no close relation in severity of clinical picture, serological and pathological alteration. For this reason the prognosis is difficult to establish. Administration of sodium thiosulphate may reduce the precipitation of calcium crystals and improve the general clinical conditions before surgical parathyroidectomy, which seems the only therapeutic approach able to reduce the mortality risk in these patients. A 60 year old female patient suffering from End Renal Stage Disease, on haemodialysis from 2001 due to the onset of haemolytic uremic syndrome, underwent a kidney transplant in April 2008. After transplantation there was a recurrence of the haemolytic uremic syndrome, with temporary worsening of the graft. Six months later there was a definite loss of graft and return to dialysis treatment. On April 2010 a severe systemic calciphylaxis related to secondary hyperparathyroidism was diagnosed. The patient underwent parathyroidectomy but, because of the unimproved clinical picture, treatment with sodium thiosulphate was initiated. There was only improvement in cutaneous lesions. The worsening general clinical condition of the patient caused death due to general septic complications. The coexistence of haemolytic uremic syndrome and secondary hyperpathyroidism makes the prognosis poor and, in this case, therapy, which counteracts calcium crystals precipitation, has no effect. Preventive parathyroidectomy can be considered as the only possible treatment.

Post-polio syndrome (PPS) characterized by new neuromuscular problems can appear many years after acute poliomyelitis in polio survivors. We report a 77-year-old man with antecedent poliomyelitis who newly developed neuromuscular disease with a clinical course of 27 years, the final 10 years of which were characterized by apparent progression, thus raising doubt as to the clinical diagnosis of amyotrophic lateral sclerosis (ALS) following PPS. Pathologically, plaque-like, old poliomyelitis lesions were found almost exclusively in the lumbosacral cord, showing complete neuronal loss and glial scars in the anterior horns. Although less severe, neuronal loss and gliosis were also evident outside the old lesions, including the intermediate zone. Moreover, symmetrical degeneration of the corticospinal tracts, as evidenced by CD68 immunostaining, was a feature of the white matter of the lower spinal cord. In the motor cortex, loss of Betz cells was also confirmed. Synaptophysin immunostaining of the lumbosacral cord also revealed decreased expression outside the old lesions, excluding the posterior horn. Interestingly, decreased expression of synaptophysin was also evident in the cervical anterior horns, where no old lesions were observed. No Bunina bodies, TDP-43 inclusions, or Golgi fragmentation were found. Neurogenic atrophy was evident in the iliopsoas and scalenus muscles, and inclusion body myositis-like changes were also observed in these muscles and the tongue. Was it possible to have diagnosed this patient as having ALS? We consider that the features in this case may have represented the pathology of long-standing and/or fatal PPS itself, and not ALS. © 2012 Japanese Society of Neuropathology.

Trypanosoma cruzi infection via oral route results in outbreaks or cases of acute Chagas disease (ACD) in different Brazilian regions and poses a novel epidemiological scenario. In the Espírito Santo state (southeastern Brazil), a fatal case of a patient with ACD led us to investigate the enzootic scenario to avoid the development of new cases. At the studied locality, Triatoma vitticeps exhibited high T. cruzi infection rates and frequently invaded residences. Sylvatic and domestic mammals in the Rio da Prata locality, where the ACD case occurred, and in four surrounding areas (Baia Nova, Buenos Aires, Santa Rita and Todos os Santos) were examined and underwent parasitological and serological tests. Triatomines were collected for a fecal material exam, culturing and mini-exon gene molecular characterization, followed by RFLP-PCR of H3/Alul. Paraffin-embedded cardiac tissue of a patient was washed with xylene to remove paraffin and DNA was extracted using the phenol-chloroform method. For genotype characterization, PCR was performed to amplify the 1f8, GPI and 18S rRNA genes. In the case of V7V8 SSU rRNA, the PCR products were molecularly cloned. PCR products were sequenced and compared to sequences in GenBank. Phylogenetic analysis using maximum likelihood method with 1000 bootstrap replicates was performed. None of the animals showed positive hemocultures. Three rodents and two dogs showed signs of infection, as inferred from borderline serological titers. T. vitticeps was the only triatomine species identified and showed T. cruzi infection by DTUs TcI and TcIV. The analysis of cardiac tissue DNA showed mixed infection by T. cruzi (DTUs I, II, III and IV) and Trypanosoma dionisii. Each case or outbreak of ACD should be analyzed as a particular epidemiological occurrence. The results indicated that mixed infections in humans may play a role in pathogenicity and may be more common than is currently recognized. Direct molecular characterization from biological
Full Text Available The case fatality ratio (CFR of Ebola virus disease (EVD can vary over time and space for reasons that are not fully understood. This makes it difficult to define the baseline CFRs needed to evaluate treatments in the absence of randomized controls. Here, we investigate whether viremia in EVD patients may be used to evaluate baseline EVD CFRs.We analyzed the laboratory and epidemiological records of patients with EVD confirmed by reverse transcription PCR hospitalized in the Conakry area, Guinea, between 1 March 2014 and 28 February 2015. We used viremia and other variables to model the CFR. Data for 699 EVD patients were analyzed. In the week following symptom onset, mean viremia remained stable, and the CFR increased with viremia, V, from 21% (95% CI 16%-27% for low viremia (V < 104.4 copies/ml to 53% (95% CI 44%-61% for intermediate viremia (104.4 ≤ V < 105.2 copies/ml and 81% (95% CI 75%-87% for high viremia (V ≥ 105.2 copies/ml. Compared to adults (15-44 y old [y.o.], the CFR was larger in young children (0-4 y.o. (odds ratio [OR]: 2.44; 95% CI 1.02-5.86 and older adults (≥ 45 y.o. (OR: 2.84; 95% CI 1.81-4.46 but lower in children (5-14 y.o. (OR: 0.46; 95% CI 0.24-0.86. An order of magnitude increase in mean viremia in cases after July 2014 compared to those before coincided with a 14% increase in the CFR. Our findings come from a large hospital-based study in Conakry and may not be generalizable to settings with different case profiles, such as with individuals who never sought care.Viremia in EVD patients was a strong predictor of death that partly explained variations in CFR in the study population. This study provides baseline CFRs by viremia group, which allow appropriate adjustment when estimating efficacy in treatment studies. In randomized controlled trials, stratifying analysis on viremia groups could reduce sample size requirements by 25%. We hypothesize that monitoring the viremia of hospitalized patients may inform the

Full Text Available Spring viraemia of carp (SVC is a fatal viral disease for cyprinid fish, which is caused by spring viraemia of carp virus (SVCV. To date, no SVC outbreak has been reported in China. Between 1998 and 2002, outbreaks of SVC were reported in ornamental and wild fish in Europe and America, imported from multiple sources including China. Based on phylogenetic analysis, the viral strain isolated from America was shown to be originated from Asia. These outbreaks not only resulted in huge economic losses, but also raise an interesting question as to whether SVCV really exists in China and if so, is it responsible for SVC outbreaks? From 2002 to 2006, we screened 6700 samples from ornamental fish farms using the cell culture method of the Office International des Epizooties (OIE, and further verified the presence of SVCV by ELISA and real-time quantitative RT-PCR. Two infected samples were found and the complete genome of SVCV was sequenced from one of the isolates, termed SVCV-C1. Several unique hallmarks of SVCV-C1 were identified, including six amino acid (KSLANA insertion in the viral RNA-dependent RNA polymerase (L protein and ten nucleotide insertion in the region between glycoprotein (G and L genes in European SVCV strains. Phylogenetic tree analysis of the full-length G protein of selected SVCV isolates from the United Kingdom and United States revealed that G proteins could be classified into Ia and Id sub genogroups. The Ia sub genogroup can be further divided into newly defined sub genogroups Ia-A and Ia-B. The isolates derived from the United States and China including the SVCV-C1 belongs to in the Ia-A sub genogroup. The SVCV-C1 G protein shares more than 99% homology with the G proteins of the SVCV strains from England and the United States, making it difficult to compare their pathogenicity. Comparison of the predicted three-dimensional structure based on the published G protein sequences from five SVCV strains revealed that the main

Full Text Available Colchicine is an alkaloid extracted from autumnal Colchicum plant which is used primarily for its anti-inflammatory therapy effect. Acute intoxication with colchicine is uncommon but often severe and results in multiple visceral organ dysfunctions. The intoxication severity and mortality are directly depending on the ingested dose. The treatment is manly symptomatic. However, the development of specific anti-colchicine immunotherapy would offer a new therapeutic perspective. Authors report a case of a young patient that ingested 40 tablets colchicine, which caused a multiple organ failure and with fatal outcome.

Respiratory diseases cause substantial morbidity and mortality worldwide, with sub-Saharan Africa bearing the greatest burden. Identifying etiologies of respiratory disease is important to inform cost effective treatment, prevention and control strategies. Testing for all of the different pathogens that are potentially associated with respiratory illnesses is challenging. We piloted the use of a multi-pathogen respiratory Taqman Array Cards (TAC) to identify pathogens in respiratory samples collected from non-fatal and fatal cases and their matched asymptomatic controls. This is a case control study comparing viral and bacterial pathogens detected among non-fatal and fatal cases to those detected among age and time matched asymptomatic controls. We used McNemar's test to compare proportions of pathogens detected among cases (non-fatal and fatal) to their matched asymptomatic controls. We used Mann-Whitney test to compare the distribution of median Cycle threshold (Ct) values among non-fatal and fatal cases to their corresponding asymptomatic controls. There were 72 fatal and 72 non-fatal cases matched to 72 controls. We identified at least one pathogen in 109/144 (76%) cases and 59/72 (82%) controls. For most pathogens, the median Ct values were lower among cases (fatal and non-fatal) compared to asymptomatic controls. Similar rates of pathogen detection among cases and controls make interpretation of results challenging. Ct-values might be helpful in interpreting clinical relevance of detected pathogens using multi-pathogen diagnostic tools.

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.

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.

Full Text Available Paraquat (1, 1′-dimethyl-4, 4′-dipyridylium is a bipyridilium herbicide used widely in our country and is a highly toxic compound. This compound is very notorious to cause rapid development of renal, liver, and respiratory failure with very high mortality due to lack of specific antidote and dearth of high-quality evidence-based treatment. Respiratory system involvement is the most common cause of death in these people. We hereby report a fatal case of a 30-year-old male with a history of paraquat consumption. The patient developed oliguric renal failure, deterioration of liver function, and acute respiratory distress syndrome over next few days. Different treatment modalities were tried to manage patient′s condition. In this case, none of the strategies worked well, and death ensued due to multi-organ dysfunction syndrome.
Full Text Available ABSTRACT Even though fatalism has been an intermittent topic of philosophy since Greek antiquity, this paper argues that fate ought to be of little concern to metaphysicians. Fatalism is neither an interesting metaphysical thesis in its own right, nor can it be identified with theses that are, such as realism about the future or determinism.
Full Text Available To characterize the clinical features of fatal asthma, we retrospectively analyzed the clinical characteristics of patients who died of an acute asthma attack in our hospital during a 15-year period from 1989 to 2003. Twelve patients had fatal asthma during this period, including eight who were dead on arrival in the emergency room (ER and three who died within 1 hour of admission to the ER. Patients were categorized into three groups according to the clinical presentations during the fatal attack: (1 rapid (< 3 hours decompensation in four patients; (2 gradual development of respiratory failure over several days in two patients; and (3 acute deterioration after unstable asthma lasting several days in six patients. All patients in groups 1 and 2 had reported previous near-fatal attacks. The proportion of young patients was highest in group 3, with half of them (3/6 younger than 35 years of age. Only one patient in group 3 had had a previous near-fatal attack. Five of the seven patients, with previous near-fatal attacks, had a pattern of decompensation during their fatal attack that was similar to their previous attacks. In conclusion, nearly all patients with fatal asthma in this study died outside of the hospital or within 1 hour after admission to the ER. Patients had patterns of decompensation during the fatal attack that were similar to those of their previous attacks. Early detection of warning signs, early admission to the ER, adequate treatment, and extremely close observation of patients, especially within 1 hour after ER arrival, may prevent or decrease the incidence of fatal asthmatic attack.

Full Text Available 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.
Full Text Available Background. Since the introduction of diquat in agriculture practice in 1960's, about 40 cases of poisoning have been described in detail in medical literature. Case report. We presented two cases. A case one, a 35-year-old, previously healthy, woman ingested 14% diquat solution. The poisoning had fulminant course, consisted of severe stomachache, vomiting, cardiocirculatory shock, respiratory failure and cardiac arrest 20 hours post-ingestion. Autopsy revealed myocardial infarction, bronchopneumonia and incipient renal damage. A case two, a 64-year-old man developed severe gastroenteritis, corrosive lesions of mucosal surfaces, acute renal injury, arrhythmias, brain stem infarction and bronchopneumonia. The diagnosis of diquat poisoning was made retrospectively upon the clinical picture and identification of pesticides he had been exposed to. The patient died 18 days post-exposure. The most prominent findings on autopsy were pontine hemorrhage and infarction, bronchopneumonia, left ventricle papillary muscle infarction and renal tubular damage. Conclusion. Cardiocirculatory disturbances led to fatal complications, the heart and brain infarction. We pointed out the heart as one of the most severely affected organs in diquat poisoning.

Drowning is a newly comprehended public health concern in Fiji. Defined as "the process of experiencing respiratory impairment from submersions or immersion in liquid," drowning has been identified as one of Fiji's 5 leading causes of death for those aged 1 to 29 years. The aim of this article was to develop the most parsimonious model that can be used to explain the number of monthly fatal drowning cases in Fiji. Based on a cross-section of 187 drowning incidents from January 2012 to April 2015, this observational study found the number of monthly drownings in Fiji was significantly affected by monthly rainfall ( P = .008, 95% confidence interval = 0.10-0.62) and the number of days comprising public holidays/weekends ( P = .018, 95% confidence interval = 0.06-0.60). Furthermore, the multiple coefficient of determination ( r 2 = .4976) indicated that almost half the variation in drownings was explained by rainfall and public holidays/weekend periods. Inadequate supervision, an inability to identify or carry out safe rescue techniques, and limited water-safety knowledge were identified as common risk factors. To overcome this preventable cause of death, technically guided interventions need to be actively embedded into a range of government policies and community health promotions, disaster management, and education programs.

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.

In daily medical practice, streptococcal toxic shock syndrome is an infrequent clinical entity which carry a very high risk of fatality. Early recognition of this toxin mediated immunopathological disease is very important to apply necessary invasive procedures such as an prompt amputation of the effected areas to save the patient. Here, we report a 47 year-old male farmer with a fatal streptococcal toxic shock syndrome to highlight the importance of emergency care and aggresive surgical intervention in similar situations.
Full Text Available In this paper, the author explores ideas of how to approach the subject of fate and fatalism. Fate, when equated with a man's life, can be raised to an infinite number of powers—as illustrated in the well-known story of the philosopher who began to wonder whether he were awake or dreaming himself awake. It would be fertile for the study of Fatalism to devote itself to analyses of situations with a view to ascertaining in which situations Fatalism is used. It would be very interesting then to examine whether the typical situations of Fatalism are not such as exclude the application of religious, magical, or rational behaviour.

Child maltreatment remains a problem in the United States, and individual poverty is a recognized risk factor for abuse. Children in impoverished communities are at risk for negative health outcomes, but the relationship of community poverty to child abuse fatalities is not known. Our objective was to evaluate the association between county poverty concentration and rates of fatal child abuse. This was a retrospective, cross-sectional analysis of child abuse fatalities in US children 0 to 4 years of age from 1999 to 2014 by using the Centers for Disease Control and Prevention Compressed Mortality Files. Population and poverty statistics were obtained from US Census data. National child abuse fatality rates were calculated for each category of community poverty concentration. Multivariate negative binomial regression modeling assessed the relationship between county poverty concentration and child abuse fatalities. From 1999 to 2014, 11 149 children 0 to 4 years old died of child abuse; 45% (5053) were poverty concentration had >3 times the rate of child abuse fatalities compared with counties with the lowest poverty concentration (adjusted incidence rate ratio, 3.03; 95% confidence interval, 2.4-3.79). Higher county poverty concentration is associated with increased rates of child abuse fatalities. This finding should inform public health officials in targeting high-risk areas for interventions and resources. Copyright © 2017 by the American Academy of Pediatrics.

The investigation, epidemiology, and effectiveness of control procedures during an outbreak of Legionnaires' disease involving three immunosuppressed patients are described. The source of infection appeared to be a network of fire hydrant spurs connected directly to the incoming hospital mains water supply. Removal of these hydrants considerably reduced, but failed to eliminate, contamination of water storage facilities. As an emergency control procedure the incoming mains water was chlorinated continuously. Additional modifications to improve temperature regulation and reduce stagnation also failed to eliminate the legionellae. A perspex test-rig was constructed to model the pre-existing hospital water supply and storage system. This showed that through the hydraulic mechanism known as 'temperature buoyancy', contaminated water could be efficiently and quickly exchanged between a stagnant spur pipe and its mains supply. Contamination of hospital storage tanks from such sources has not previously been considered a risk factor for Legionnaires' disease. We recommend that hospital water storage tanks are supplied by a dedicated mains pipe without spurs. PMID:8005217

Raptors may contract highly pathogenic avian influenza virus H5N1 by hunting or scavenging infected prey. However, natural H5N1 infection in raptors is rarely reported. Therefore, we tested raptors found dead during an H5N1 outbreak in wild waterbirds in Mecklenburg-Western Pomerania, Germany, in 2006 for H5N1-associated disease. We tested 624 raptors of nine species-common buzzard (385), Eurasian sparrowhawk (111), common kestrel (38), undetermined species of buzzard (36), white-tailed sea eagle (19), undetermined species of raptor (12), northern goshawk (10), peregrine falcon (6), red kite (3), rough-legged buzzard (3), and western marsh-harrier (1)-for H5N1 infection in tracheal or combined tracheal/cloacal swabs of all birds, and on major tissues of all white-tailed sea eagles. H5N1 infection was detected in two species: common buzzard (12 positive, 3.1%) and peregrine falcon (2 positive, 33.3%). In all necropsied birds (both peregrine falcons and the six freshest common buzzards), H5N1 was found most consistently and at the highest concentration in the brain, and the main H5N1-associated lesion was marked non-suppurative encephalitis. Other H5N1-associated lesions occurred in air sac, lung, oviduct, heart, pancreas, coelomic ganglion, and adrenal gland. Our results show that the main cause of death in H5N1-positive raptors was encephalitis. Our results imply that H5N1 outbreaks in wild waterbirds are more likely to lead to exposure to and mortality from H5N1 in raptors that hunt or scavenge medium-sized birds, such as common buzzards and peregrine falcons, than in raptors that hunt small birds and do not scavenge, such as Eurasian sparrowhawks and common kestrels.

Circulating inflammatory markers may more strongly relate to risk of fatal versus nonfatal cardiovascular disease (CVD) events, but robust prospective evidence is lacking. We tested whether interleukin (IL)-6, C-reactive protein (CRP), and fibrinogen more strongly associate with fatal compared to nonfatal myocardial infarction (MI) and stroke.

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.

A chronic pulmonary disease was encountered in nude mice of a barrier sustained colony, and Pneumocystis carinii was identified as the causative agent histopathologically as well as on impression smear preparations in the affected lungs. Fatal infection was seen only in old nude mice aged more than 6 months, while focal pulmonary lesions were developed without clinical signs in young adult nudes 2 to 3 months of age. The lesions produced in aged nude mice were characterized by propagation of mononuclear cells with the presence of foamy masses of P. carinii. Heterozygous littermates were much less susceptible to the infection but pneumocystic lesions could be produced readily by multiple treatment with immunosuppressants. The infection could be transmitted without immunosuppressant to non-infected nudes but not to heterozygous littermates after intranasal inoculation of affected tissue emulsion or by cage mating with severely affected nudes.

An increase in the awareness of the problem of gunshot fatalities in children has occurred nationwide over the last year. Unintentional firearm deaths are more common among children and young adults. These deaths may be addressed by preventive measures beyond those available for pediatric firearm suicide and homicide. This study focuses on the incidence of fatal gunshot injuries in children under 16 years of age during the years 1979 through 1987 in our state. Over the past 9 years 132 children (0 to 16 years) were shot and killed as a result of firearm injuries (M:F ratio, 3:1). No difference in absolute number in racial distribution existed. Deaths were classified as homicide, 61 (46%); accidental, 33 (25%); suicide, 29 (22%); undetermined, 7 (5%); and other, 2 (1.5%). Over 70% of these fatal injuries occurred in the home environment. Types of weapons involved included handguns (48%), shotguns (22%), rifles (17%), unspecified weapon (12%), and air rifle (1%). In a large number of cases, guns were found in the home unsecured. The perpetrator was known by the victim in 64 instances, while unknown in 27. Thirty-nine self-inflicted wounds and two shotgun blasts in the line of fire accounted for the remaining deaths. The most common anatomical injury and ultimate cause of death was cranial central nervous system (CNS) (62%), followed by chest/mediastinum (20%), abdomen (10%), and other (8%). A child who has sustained a firearm injury is more likely to know the perpetrator, be killed in the home by a readily available unsecured firearm, and die from severe head injury.

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.

A series of 51 fatal cases of accidental hypothermia in northern Sweden has been reviewed. The cases conform well to previous investigations with respect to the mean age of the victims (48 years) and a predominance of males. The cases occurred mainly during the winter months and on Saturdays. Most cases succumbed at temperatures below -10 degrees C. The most frequent necropsy findings were areas of frostbite with purple discoloration of the skin, reddish lividity and superficial erosions of the gastric mucosa. Paradoxical undressing was present in more than half of the cases. About two thirds of the cases were under the influence of alcohol with a mean blood alcohol concentration of 1.6 g/l. Furthermore, at least half of the cases could be considered habitual drunkards. In conclusion, the present series shows two main groups of fatal hypothermia victims: one group of elderly persons, mostly chronic abusers and under the influence of alcohol (approximately two-thirds of the series), and another of younger and sober persons, performing recognised sporting activities (approximately one-fourth of the series).

Biochemical diagnostics of fatal opium intoxication remains a topical problem in forensic medical science and practice. We investigated materials obtained in the course of forensic medical expertise of the cases of fatal opium intoxication. The study revealed significant differences between myoglobin levels in blood, urine, myocardium, and skeletal muscles. The proposed approach to biochemical diagnostics of fatal opium intoxication enhances the accuracy and the level of evidence of expert conclusions.

Cancer fatalism--the belief that death is inevitable when cancer is present--has been identified as a barrier to participation in cancer screening, detection, and treatment. Yet this literature has not been reviewed in a comprehensive and systematic manner. Therefore, this literature review addressed (1) philosophical and theoretical underpinnings of cancer fatalism; (2) relationships among demographic factors, cancer fatalism, and cancer screening; (3) the role of cancer fatalism for patients diagnosed with cancer; and (4) intervention strategies. Most of the reviewed studies were descriptive or correlational, did not have an explicit theoretical framework, had varied definitions of fatalism, and reported screening as "intent to screen" or as "past screening behaviors." Review of the studies suggests that cancer fatalism develops over time and is most frequently reported among medically underserved persons and those with limited knowledge of cancer. Cancer fatalism may be modified through culturally relevant interventions that incorporate spirituality. Emphasis must be placed on recognizing the role of cancer fatalism when planning health promotion activities. Future studies should focus on the consistent measurement of cancer fatalism and testing intervention strategies.

African American men present at later stages of testicular cancer and have higher mortality rates than Caucasian men. Lack of awareness, beliefs, and access to care may influence this disparity. Guided by the Powe fatalism model, this comparative study assessed knowledge of testicular cancer, perceived risk, and cancer fatalism among African American and Caucasian men who attended selected colleges and universities. Data were collected using the Powe Fatalism Inventory, the Testicular Cancer Knowledge Survey, and the Perceived Cancer Risk Survey. The majority (n = 190) of men were African American (70%), and the remainder were Caucasian. African American men were significantly younger than Caucasian men. African American men also had lower testicular cancer knowledge scores, higher perceptions of cancer fatalism, and lower perceived risk for the disease. Rates of testicular cancer screening were low for all the men. Research should focus on further understanding the relationship between cancer fatalism and health-promoting behaviors among African American men.

Full Text Available Death certificate data from the Multiple Cause of Death (MCOD files were analyzed to better understand the drug categories most responsible for the increase in fatal overdoses occurring between 1999 and 2014. Statistical adjustment methods were used to account for the understatement in reported drug involvement occurring because death certificates frequently do not specify which drugs were involved in the deaths. The frequency of combination drug use introduced additional uncertainty and so a distinction was made between any versus exclusive drug involvement. Many results were sensitive to the starting and ending years chosen for examination. Opioid analgesics played a major role in the increased drug deaths for analysis windows starting in 1999 but other drugs, particularly heroin, became more significant for recent time periods. Combination drug use was important for all time periods and needs to be accounted for when designing policies to slow or reverse the increase in overdose deaths.

Intoxication with carbon dioxide (CO2), a nonexplosive, colorless, and odorless gas does not cause any clinical symptoms or signs, with the occasional exception of sudation. Carbon dioxide is principally used in the food industry (70% of CO2 production), in particular to preserve foods and to carbonate beverages. Most fatalities resulting from CO2 intoxication are accidental and occur either in closed spaces or when dry ice is used in the food industry. In this case report, a 42-year-old male winemaker engineer was found dead, his head inside a wine vat that had been filled with grapes on the previous day and supplemented with dry ice to improve the taste of wine.

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.

Respiratory diseases have a major impact on racehorses in training and are often cited as the second most common reason of horses failing to perform. Cases were submitted by the California Horse Racing Board to the California Animal Health and Food Safety laboratory for postmortem examination between January 1, 2005 and December 31, 2014. We determined the demographics of racehorses with fatal pneumonia, characterized the pathologic findings in animals with a postmortem diagnosis of respiratory infection, and determined the most significant pathogens associated with lower respiratory tract disease. We analyzed autopsy reports from 83 horses with a diagnosis of pneumonia, bronchopneumonia, and/or pleuropneumonia. The most common presentation was pleuropneumonia (71% of cases), with extensive areas of lytic necrosis and abscesses of the pulmonary parenchyma. Streptococcus equi ssp. zooepidemicus, a normal mucosal commensal of the upper respiratory tract of healthy horses, was the most commonly isolated organism (72% of cases), either in pure culture or accompanied by other aerobic or anaerobic bacteria. Its presence in the pulmonary parenchyma is associated with severe and extensive damage to the lung. Furthermore, this agent has zoonotic potential, which stresses the importance of early detection and proper management of cases of pneumonia in racehorses.

Weather has a direct impact on traffic safety. This study focuses on fatal crashes in the presence of rain. We reviewed information related to the events that lead to rain- related crashes in the Texas since 1982. Analysis of the data reveals that 12.4% of crashes in Texas were rain-related. Most rain-related crashes are located in Texas "Flash Flood Alley" which includes major urban centers. Fatal crash data and GIS are used to explore and identify the spatio-temporal distribution of the crashes. Spatial statistical techniques are used to identify significant patterns of rain-related fatal crashes. Logistic and nonlinear regression is used to identify and rank all environmental and non-environmental factors that contribute to fatal crashes. Focus will be on factors that amplify the rain effect. Identifying the variables contributing to these fatal crash types is necessary for the implementation of effective countermeasures for road weather safety purposes.

Minoxidil is a direct-acting peripheral vasodilator for the treatment of symptomatic hypertension, or refractory hypertension associated with target organ damage, that is not manageable with a diuretic and two other antihypertensive drugs. The most frequent adverse events associated with minoxidil include hypertrichosis and cardiovascular events related to its powerful antihypertensive effect, and less frequently, rashes, bullous eruptions, and Stevens-Johnson syndrome (SJS). Evidence suggests that SJS and toxic epidermal necrolysis (TEN) are variants of a single disease with common causes and mechanisms, but differing severities. Epidermal detachment is mild in SJS, moderate in overlap SJS-TEN, and severe (> 30% of body surface area) in TEN. We describe a case of minoxidil-associated SJS that evolved into fatal TEN. A 69-year-old African-American woman with a history of chronic kidney disease was admitted to the hospital for a cerebrovascular accident and uncontrolled hypertension. On hospital day 12, oral minoxidil was added to her drug regimen. On day 23, she developed a maculopapular rash on her face that gradually diffused to her chest and back. Vesicles and papular lesions extended to her extremities and mucosal membranes; results of a skin biopsy revealed SJS. A positive Nikolsky's sign (blisters spread on application of pressure) was detected. On days 27-31, diffuse bullae developed with rash exacerbation. Skin detachment exceeded 30% and was consistent with TEN. The patient died on day 39. An evaluation of the causality and time course suggested that minoxidil was the most likely culpable drug, with a Naranjo adverse drug reaction probability scale score indicating that the likelihood of the association was possible (score of 3). The mechanism of this reaction has not been well elucidated. It may be related to an impaired clearance of the minoxidil metabolite, or an immune stimulation resulting in apoptosis and epidermis destruction. To our knowledge, this
Full Text Available Introduction. Necrotizing fasciitis is an uncommon condition in general practice but one that provokes serious morbidity. It is characterized by widespread fascial necrosis with relative sparing of skin and underlying muscle. Herein, we report a fatal case of necrotizing fasciitis in a young healthy woman after episiotomy. Case Report. A 17-year-old primigravida underwent a vaginal delivery with mediolateral episiotomy. Necrotizing fasciitis was diagnosed on the 5th postpartum day, when the patient was referred to our tertiary care medical center. Surgical debridement was initiated together with antibiotics and followed by hyperbaric oxygen therapy. The patient died due to septic shock after 16 hours from the referral. Conclusion. Delay of diagnosis and consequently the surgical debridement were most likely the reasons for maternal death. In puerperal period, a physician must consider necrotizing fasciitis as a possible diagnosis in any local sings of infection especially when accompanied by fever and/or tenderness. Early diagnosis is the key for low mortality and morbidity.

This study examines recent trends and patterns in fall fatalities in the U.S. construction industry to determine whether fatal falls among older workers are different from younger workers in this industry. Falls are the leading cause of fatalities in the U.S. construction industry. Given the increasingly aging workforce in construction, it is important to assess the risk of falls among older construction workers. Fatality data were obtained from the Census of Fatal Occupational Injuries for the years 1992 through 2008. Denominators for death rates were estimated from the Current Population Survey. Stratified and multivariate analyses were performed to examine whether there are differences in fatal falls between older workers (> or = 55 years) and younger workers (16-54 years). Fatal falls in nonconstruction industries were excluded from this study. Older workers had higher rates of fatal falls than younger workers; results were significant in 11 of 14 construction occupations. Regression analysis indicated that older decedents had a higher likelihood that work-related death was caused by a fall, after controlling for major demographic and employment factors (odds ratio = 1.50, confidence interval [1.30, 1.72]). Falls from roofs accounted for one third of construction fatal falls, but falls from ladders caused a larger proportion of deadly falls in older decedents than in younger decedents. Older workers have a higher likelihood of dying from a fall. Roofs and ladders are particularly risky for older construction workers. As the construction workforce ages, there is an urgent need to enhance fall prevention efforts, provide work accommodations, and match work capabilities to job duties.

Sporadic fatal insomnia (sFI) is a rapid progressive neurodegenerative disease characterised by gradual to perpetual insomnia, followed by dysautonomia, coma and death. 1 The cause of sFI was recently mapped to a mutation in a protein, the prion, found in the human brain. It is the unfolding of the prion that leads to the generation of toxic oligomers that destroy brain tissue and function. Recent studies have confirmed that a methionine mutation at codon 129 of the human Prion is characteristic of sFI. Current treatment slows down the progression of the disease, but no cure has been found, yet. We used Molecular Docking and Molecular Dynamics simulation methods, to study the toxic Fatal-Insomnia-prion conformations at local unfolding. The idea was to determine these sites and to stabilise these regions against unfolding and miss-folding, using a small ligand, based on a phenothiazine "moiety". As a result we here discuss current fatal insomnia therapy and present seven novel possible compounds for in vitro and in vivo screening.

Fatalism may play a role in Appalachians' views about cancer screening and contribute to high rates of cancer incidence and mortality, but few studies have explored this issue. A probability telephone survey was conducted of 696 adults living in 51 Appalachian Kentucky counties inquiring about intentions to obtain cancer screening. The Life Orientation Test-Revised as a surrogate measure for fatalism and logistic regression was used to predict screening activity. Insurance coverage was the best overall predictor variable. Fatalism was significant in one model possibly reflecting an appreciation of the costs and barriers associated with obtaining screening in rural counties.
Child death reviews are conducted with the aim of preventing child deaths however, definitions, inclusion criteria for the review of child deaths and reporting practices vary across Child Death Review Teams (CDRTs). This article aims to identify a common context and understanding of fatal neglect reporting by reviewing definitional issues of fatal neglect and comparing reporting practice across a number of CDRTs. Providing a consistent context for identifying and reporting neglect-related deaths may improve the understanding of the impact of fatal neglect and the risk factors associated with it and therefore, improve the potential of CDRT review to inform prevention programs, policies, and procedures.

State-level injury rates or fatality rates are sometimes used in studies of the impact of various safety programs or other state policies. How much does the metric used affect the view of relative occupational risks among U.S. states? This paper uses a measure of severe injuries (fatalities) and of less severe injuries (non-fatal injuries with days away from work, restricted work, or job transfer-DART) to examine that issue. We looked at the correlation between the average DART injury rate (from the BLS Survey of Occupational Injuries and Illnesses) and an adjusted average fatality rate (from the BLS Census of Fatal Occupational Injuries) in the construction sector for states for 2003-2005 and for 2006-2008. The RAND Human Subjects Protection Committee determined that this study was exempt from review. The correlations between the fatal and non-fatal injury rates were between -0.30 and -0.70 for all construction and for the subsector of special trade contractors. The negative correlation was much smaller between the rate of fatal falls from heights and the rate of non-fatal falls from heights. Adjusting for differences in the industry composition of the construction sector across states had minor effects on these results. Although some have suggested that fatal and non-fatal injury rates should not necessarily be positively correlated, no one has suggested that the correlation is negative, which is what we find. We know that reported non-fatal rates are influenced by workers' compensation benefits and other factors. Fatality rates appear to be a more valid measure of risk. Efforts to explain the variations that we find should be undertaken. Copyright © 2012 Wiley Periodicals, Inc.

The long-term prognostic value of a standard 12-lead electrocardiogram (ECG) for predicting cardiac events in apparently healthy middle-aged subjects is not well defined. A total of 9511 middle-aged subjects (mean age 43 ± 8.2 years, 52% males) without a known cardiac disease and with a follow-up 40 years were included in the study. Fatal and non-fatal cardiac events were collected from the national registries. The predictive value of ECG was separately analyzed for 10 and 30 years. Major ECG abnormalities were classified according to the Minnesota code. Subjects with major ECG abnormalities (N = 1131) had an increased risk of cardiac death after 10-years (adjusted hazard ratio [HR] 1.7; 95% confidence interval [95% CI], 1.1-2.5, p = 0.009) and 30-years of follow-up (HR 1.3, 95% CI, 1.1-1.5, p electrocardiogram are shown to have prognostic significance for cardiac events in elderly subjects without known cardiac disease. Our results suggest that ECG abnormalities increase the risk of fatal cardiac events also in middle-aged healthy subjects.

for death from accidents among persons with MS was 37% higher than that of the general population (SMR = 1.37). We found no significant excess risk for fatal road accidents (SMR = 0.80). The risk for falls was elevated (SMR = 1.29) but not statistically significantly so. The risks were particularly high......-1996. The end of follow-up was 1 January 1999. We calculated standardized mortality ratios (SMRs) for various types of fatal accidents. A total of 76 persons (48 men and 28 women) died from accidents, whereas the expected number of fatalities from such causes was 55.7 (31.4 men and 24.3 women). Thus, the risk...... for deaths from burns (SMR = 8.90) and suffocation (SMR = 5.57). We conclude that persons with MS are more prone to fatal accidents than the general population. The excess risk is due not to traffic accidents but to burns and suffocation....

This research examined fatalism, the belief in external control over life chances, as a risk factor for adolescent depression. Data were analyzed from a large (N = 5,423) sample of adolescents attending middle school in an ethnically diverse community in the southwest. It was hypothesized that adolescents who demonstrated greater fatalism would have a higher risk for depression. Bivariate associations between fatalism and depression were substantial, with an odds ratio (OR) of nearly 25 for depression with impairment and nearly 13 for depression without impairment. Adjustment for the effects of 10 covariates drawn from three domains (status attributes, stressors, and personal/social resources) essentially eliminated the association between fatalism and depression with impairment. However, the OR was still 2.6. The significant association between fatalism and depression without impairment (OR = 2.7) remained after adjustment for covariates. The results provide further support for models of depression which emphasize the role of psychosocial deficits. In this case, we found depression was associated not only with greater fatalism but also greater pessimism, lower self-esteem, more passive coping, and less social support.

Clinical presentation and physical signs may be unreliable in the diagnosis of stercoral colitis (SC). This study evaluates the value of computed tomography (CT) in distinguishing fatal from non-fatal SC. Ten patients diagnosed as SC were obtained from inter-specialist conferences. Additional 13 patients with suspected SC were identified via the Radiology Information System (RIS). These patients were divided into two groups; fatal and non-fatal SCs. Their CT images are reviewed by two board-certified radiologists blinded to the clinical data and radiographic reports. SC occurred in older patients and displayed no gender predisposition. There was significant correlation between fatal SC and CT findings of dense mucosa (p 0.017), perfusion defects (p = 0.026), ascites (p = 0.023), or abnormal gas (p = 0.033). The sensitivity, specificity, and accuracy of dense mucosa were 71%, 86%, and 81%, respectively. These figures were 75%, 79%, and 77% for perfusion defects; 75%, 80%, and 78% for ascites; and 50%, 93%, and 78% for abnormal gas, respectively. Each CT sign of mucosal sloughing and pericolonic abscess displayed high specificity of 100% and 93% for diagnosing fatal SC, respectively. However, this did not reach statistical significance in diagnosing fatal SC. CT appears to be valuable in discriminating fatal from non-fatal SC.

Information regarding physiopathology and complications in fatal cases of chikungunya virus (CHIKV) is scarce. The aim of this study was to describe the frequency and severity of renal complications in fatal cases associated with CHIKV infection based on the clinical and histopathological features from post-mortem tissue biopsies. This retrospective study included fatal cases associated with CHIKV infection occurring from September 2014 through October 2015, reported to National System for Public Health Surveillance (SIVIGILA) and laboratory-confirmed by the National Institute of Health of Colombia. Medical records from 13 patients were available. Information was collected on history, physical examination, and haematological, biochemical, radiological, and virologic investigation reports. Diagnosis of CHIKV infection was performed by positive CHIKV-PCR on post-mortem tissue in 10 cases, positive CHIKV-PCR in serum in 6 cases and anti-CHIKV virus IgM in 2 cases. Only 3 cases were children (≤5 years old). Four cases had underlying diseases, mainly systemic arterial hypertension. The median value of creatinine at admission was 2.8 mg/dL (interquartile range 1.52-4.51). During hospitalization, 9 cases required ICU admission, 8 vasopressor support and 6 mechanical ventilation. Kidney histopathological findings were mainly acute interstitial nephritis (11 cases), congestion/oedema glomerular (10 cases) and acute tubular necrosis (5 cases). Renal impairment in fatal cases of CHIKV infection is frequent and related mainly to acute interstitial nephritis. These data demonstrate evidence of acquired kidney injuries during CHIKV infection.

Dam failures can lead to catastrophes on human society. However, there is a lack of research about dam break fatalities, especially on the key factors that affect fatalities. Based on the analysis of historical dam break cases, most studies have used the regression analysis to explore the correlation between those factors and fatalities, but without implementing optimization to find the dominating factors. In order to understand and reduce the risk of fatalities, this study has proposed a new method to select the impact factors on the fatality. It employs an improved ANN (Artificial Neural Network) combined with LOOCV (Leave-one-out cross-validation) and SFS (Stepwise Forward Selection) approach to explore the nonlinear relationship between impact factors and life losses. It not only considers the factors that have been widely used in the literature but also introduces new factors closely involved with fatalities. Dam break cases occurred in China from 1954 to 2013 are summarized, within which twenty-five cases are selected with a comprehensive coverage of geographic position and temporal variation. Twelve impact factors are taken into account as the inputs, i.e., severity of dam break flood (SF), population at risk (PR), public understanding of dam break (UB), warning time (TW), evacuation condition (EC), weather condition during dam break (WB), dam break mode (MB), water storage (SW), building vulnerability (VB), dam break time (TB), average distance from the affected area to the dam (DD) and preventive measures by government (PG).From those, three key factors of SF, MB and TB are chosen. The proposed method is able to extract the key factors, and the derived fatality model performs well in various types of dam break conditions.

The income-health gradient is a well-established finding in public health. This paper explores the gradient between income and different types of mortality: mortality that can be ameliorated via specific public policy measures, namely traffic fatalities, and mortality that is due to more “natural” causes, such as infectious disease. Using U.S. state-level data, growth in traffic mortality for 15-19 year-olds is shown to be more sensitive to initial levels of median income than growth in non-i...

Primary amebic meningoencephalitis (PAM) is a fatal disease of the central nervous system caused primarily by the free-living ameba, Naegleria fowleri. PAM is primarily associated with swimming in various types of fresh water. World literature was reviewed in order to derive a risk analysis model that would be helpful in the management of PAM. The management of PAM risk is difficult, and the prevention of PAM is almost impossible. However, it is reassuring that the cases and risks estimated by the risk model are usually small, with individual annual risk on the order of 10-6.

HIV/AIDS fatalism may impact on individuals' health-seeking behaviour and HIV-prevention efforts. This descriptive study measured levels of HIV/AIDS fatalism and documented HIV/AIDS beliefs and practices among a sample of Gabonese and Malians living in Gabon, West Africa. The Powe Fatalism Inventory-HIV/AIDS version was used to measure levels of fatalism, while a short-answer survey was used to document personal beliefs and behaviours related to HIV and AIDS among 160 people in Gabon. The mean score of HIV/AIDS fatalism for the total sample was 6.8 on a 15-point scale. Malians had a more fatalistic outlook than Gabonese (mean scores 9.4 versus 5.3), Muslims were more fatalistic than persons of other religions (mean scores 9.2 versus 5.3), while healthcare providers were less fatalistic than non-providers (mean scores 3.8 versus 7.4). People that did not believe that HIV/AIDS is a punishment from God had a lower mean score of fatalism than those who did. Most of the sample believed that AIDS is a real disease, and most did not think that only immoral people discuss HIV and AIDS. The HIV-prevention indicators that related to lower scores of fatalism included knowing HIV-positive people, having had more years of formal education, a willingness to disclose one's HIV status (if known), and experience of HIV/AIDS education. Respondents who had tested for HIV were no less fatalistic than those who had never tested. The findings provide data from a part of the world where HIV/AIDS beliefs have rarely been documented. The results indicate a need for additional studies on correlations between HIV/ AIDS fatalism, HIV-prevention behaviours, and religious belief systems.

Past research indicates that anticipating adverse outcomes, such as early death (fatalism), is associated positively with adolescents' likelihood of engaging in risky behaviors. Health researchers and criminologists have argued that fatalism influences present risk taking in part by informing individuals' motivation for delaying gratification for the promise of future benefits. While past findings highlight the association between the anticipation of early death and a number of developmental outcomes, no known research has assessed the impact of location in a context characterized by high perceptions of fatality. Using data from Add Health and a sample of 9,584 adolescents (51 % female and 71 % white) nested in 113 schools, our study builds upon prior research by examining the association between friends', school mates', and individual perceptions of early fatality and adolescent risk behaviors. We test whether friends' anticipation of being killed prior to age 21 or location in a school where a high proportion of the student body subscribes to attitudes of high fatality, is associated with risky behaviors. Results indicate that friends' fatalism is positively associated with engaging in violent delinquency, non-violent delinquency, and drug use after controlling for individual covariates and prior individual risk-taking. Although friends' delinquency accounts for much of the effect of friends' fatalism on violence, none of the potential intervening variables fully explain the effect of friends' fatalism on youth involvement in nonviolent delinquency and drug use. Our results underscore the importance of friendship contextual effects in shaping adolescent risk-taking behavior and the very serious consequences perceptions of fatality have for adolescents' involvement in delinquency and drug use.

Full Text Available BACKGROUND: A better description of the clinical and laboratory manifestations of fatal patients with dengue hemorrhagic fever (DHF is important in alerting clinicians of severe dengue and improving management. METHODS AND FINDINGS: Of 309 adults with DHF, 10 fatal patients and 299 survivors (controls were retrospectively analyzed. Regarding causes of fatality, massive gastrointestinal (GI bleeding was found in 4 patients, dengue shock syndrome (DSS alone in 2; DSS/subarachnoid hemorrhage, Klebsiella pneumoniae meningitis/bacteremia, ventilator associated pneumonia, and massive GI bleeding/Enterococcus faecalis bacteremia each in one. Fatal patients were found to have significantly higher frequencies of early altered consciousness (≤24 h after hospitalization, hypothermia, GI bleeding/massive GI bleeding, DSS, concurrent bacteremia with/without shock, pulmonary edema, renal/hepatic failure, and subarachnoid hemorrhage. Among those experienced early altered consciousness, massive GI bleeding alone/with uremia/with E. faecalis bacteremia, and K. pneumoniae meningitis/bacteremia were each found in one patient. Significantly higher proportion of bandemia from initial (arrival laboratory data in fatal patients as compared to controls, and higher proportion of pre-fatal leukocytosis and lower pre-fatal platelet count as compared to initial laboratory data of fatal patients were found. Massive GI bleeding (33.3% and bacteremia (25% were the major causes of pre-fatal leukocytosis in the deceased patients; 33.3% of the patients with pre-fatal profound thrombocytopenia (<20,000/µL, and 50% of the patients with pre-fatal prothrombin time (PT prolongation experienced massive GI bleeding. CONCLUSIONS: Our report highlights causes of fatality other than DSS in patients with severe dengue, and suggested hypothermia, leukocytosis and bandemia may be warning signs of severe dengue. Clinicians should be alert to the potential development of massive GI bleeding

Road traffic crashes are a global major problem, and should be treated as a shared responsibility. In Malaysia, road accident tragedies kill 6,917 people and injure or disable 17,522 people in year 2012, and government spent about RM9.3 billion in 2009 which cost the nation approximately 1 to 2 percent loss of gross domestic product (GDP) reported annually. The current cost ratio for fatal and non-fatal accident used by Ministry of Works Malaysia simply based on arbitrary value of 6:4 or equivalent 1.5:1 depends on the fact that there are six factors involved in the calculation accident cost for fatal accident while four factors for non-fatal accident. The simple indication used by the authority to calculate the cost ratio is doubted since there is lack of mathematical and conceptual evidence to explain how this ratio is determined. The main aim of this study is to determine the new accident cost ratio for fatal and non-fatal accident in Malaysia based on quantitative statistical approach. The cost ratio distributions will be estimated based on Weibull distribution. Due to the unavailability of official accident cost data, insurance claim data both for fatal and non-fatal accident have been used as proxy information for the actual accident cost. There are two types of parameter estimates used in this study, which are maximum likelihood (MLE) and robust estimation. The findings of this study reveal that accident cost ratio for fatal and non-fatal claim when using MLE is 1.33, while, for robust estimates, the cost ratio is slightly higher which is 1.51. This study will help the authority to determine a more accurate cost ratio between fatal and non-fatal accident as compared to the official ratio set by the government, since cost ratio is an important element to be used as a weightage in modeling road accident related data. Therefore, this study provides some guidance tips to revise the insurance claim set by the Malaysia road authority, hence the appropriate method

Full Text Available 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”.

Background Psychological stress is an independent risk factor for cardiovascular disease (CVD), but the mechanism by which stress is associated with CVD is not entirely understood. Although genetic factors are implied in both stress responsivity and cardiovascular reactivity, no studies to date have investigated their interactions with stress for cardiovascular end points. The objective was to elucidate the association and interactions between a genetic risk score (GRS), individual genetic variants and stress for three cardiovascular end points: coronary artery disease (CAD), fatal myocardial infarction (MI), non-fatal MI, and cardiovascular death. Methods and findings 18,559 participants from the Malmö Diet Cancer Study, a population-based prospective study, were included in the analyses. Cox proportional hazards regression models were used and adjusted for a large number of known predictors of cardiovascular end points. Mean follow-up time in years was 14.6 (CAD; n = 1938), 14.8 (fatal MI; n = 436), 14.8 (non-fatal MI; n = 1108), and 15.1 (cardiovascular death; n = 1071) respectively. GRS was significantly associated with increased risks of CAD (top quartile hazard ratio [HR], 1.72; 95% confidence interval [CI], 1.51–1.96), fatal MI (top quartile HR, 1.62; 95%CI, 1.23–2.15), non-fatal MI (top quartile HR, 1.55; 95%CI, 1.31–1.84), and cardiovascular death (top quartile HR, 1.29; 95%CI, 1.08–1.53). Stress was not independently associated with any end point and did not interact with GRS. Four individual genetic variants interacted unfavorably with stress for end points with mortality outcomes. Conclusion A GRS composed of 50 SNPs and predictive of CAD was found for the first time to also strongly predict fatal MI, non-fatal MI and cardiovascular death. A stress-sensitive component of the GRS was isolated on the basis of individual genetic variants that interacted unfavorably with stress. PMID:28426714

Nephrotic syndrome due to membranous glomerulonephritis is observed in 1 to 3% of patients with lung cancer. The nephrotic syndrome usually precedes the discovery of the causal tumor, but diagnosis can be concomitant or during the disease course. We describe a case of small-cell carcinoma of the lung without metastases revealed by a paraneoplastic nephrotic syndrome. Complete remission of the tumor was achieved with chemotherapy and radiotherapy with resolution of the nephrotic syndrome, but tumor progression occurred together with rapidly fatal renal failure. In this case, and the review of the literature, illustrate the association between paraneoplastic nephrotic syndrome and lung cancer, as well as the disease course and prognosis of the lung cancer and the accompanying glomerulopathy.

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.

In Denmark, fatal poisoning among drug addicts is often related to methadone. The primary mechanism contributing to fatal methadone overdose is respiratory depression. Concurrent use of other central nervous system (CNS) depressants is suggested to heighten the potential for fatal methadone toxicity. Reduced tolerance due to a short-time abstinence period is also proposed to determine a risk for fatal overdose. The primary aims of this study were to investigate if concurrent use of CNS depressants or reduced tolerance were significant risk factors in methadone-related fatalities using segmental hair analysis. The study included 99 methadone-related fatalities collected in Denmark from 2008 to 2011, where both blood and hair were available. The cases were divided into three subgroups based on the cause of death; methadone poisoning (N=64), poly-drug poisoning (N=28) or methadone poisoning combined with fatal diseases (N=7). No significant differences between methadone concentrations in the subgroups were obtained in both blood and hair. The methadone blood concentrations were highly variable (0.015-5.3, median: 0.52mg/kg) and mainly within the concentration range detected in living methadone users. In hair, methadone was detected in 97 fatalities with concentrations ranging from 0.061 to 211ng/mg (median: 11ng/mg). In the remaining two cases, methadone was detected in blood but absent in hair specimens, suggesting that these two subjects were methadone-naive users. Extensive poly-drug use was observed in all three subgroups, both recently and within the last months prior to death. Especially, concurrent use of multiple benzodiazepines was prevalent among the deceased followed by the abuse of morphine, codeine, amphetamine, cannabis, cocaine and ethanol. By including quantitative segmental hair analysis, additional information on poly-drug use was obtained. Especially, 6-acetylmorphine was detected more frequently in hair specimens, indicating that regular abuse of

Annual US pedestrian and bicyclist fatalities involving motor vehicles have each increased by 30% in just six years, reaching their highest levels in two decades. To provide information to reverse this trend, we quantified pedestrian and bicyclist fatality rates in 46 of the largest US metropolitan statistical areas (MSAs) during two five-year time periods: 1999-2003 and 2007-2011. We divided the annual average number of pedestrian and bicyclist fatalities during 1999-2003 from the Fatality Analysis Reporting System by the annual estimates of pedestrian and bicycle trips, kilometers traveled, and minutes traveled from the 2001 National Household Travel Survey (NHTS) and the annual average number of fatalities from 2007 to 2011 by similar estimates from the 2009 NHTS. The five most dangerous regions for walking during 2007-2011 averaged 262 pedestrian fatalities per billion trips while the five safest averaged 49 pedestrian fatalities per billion trips. The five most dangerous regions for bicycling averaged 458 bicyclist fatalities per billion trips while the five safest averaged 75 bicyclist fatalities per billion trips. Random-effects meta-analysis identified eight metropolitan regions as outliers with low pedestrian fatality rates, six with high pedestrian fatality rates, one with a low bicyclist fatality rate, and five with high bicyclist fatality rates. MSAs with low pedestrian and bicycle fatality rates tended to have central cities recognized as Walk Friendly Communities and Bicycle Friendly Communities for investing in pedestrian and bicycle projects and programs. Random-effects meta-regression showed that certain socioeconomic characteristics and high pedestrian and bicyclist mode shares were associated with lower MSA fatality rates. Results suggest that pedestrian and bicycle infrastructure and safety programs should be complemented with strategies to increase walking and bicycling. In particular, safety initiatives should be honed to reduce pedestrian and

Dengue virus is the most significant virus transmitted by arthropods worldwide and may cause a potentially fatal systemic disease named dengue hemorrhagic fever. In this work, dengue virus serotype 4 was detected in the tissues of one fatal dengue hemorrhagic fever case using electron immunomicroscopy and molecular methods. This is the first report of dengue virus polypeptides findings by electron immunomicroscopy in human samples. In addition, not-previously-documented virus-like particles visualized in spleen, hepatic, brain, and pulmonary tissues from a dengue case are discussed.

This research aims to estimate the relative risks of responsibility for a fatal accident linked to driving under the influence of cannabis or alcohol, the prevalence of these influences among drivers and the corresponding attributable risk ratios. A secondary goal is to estimate the same items for three other groups of illicit drugs (amphetamines, cocaine and opiates), and to compare the results to a similar study carried out in France between 2001 and 2003. Police procedures for fatal accidents in Metropolitan France during 2011 were analyzed and 300 characteristics encoded to provide a database of 4,059 drivers. Information on alcohol and four groups of illicit drugs derived from tests for positivity and potential confirmation through blood analysis. The study compares drivers responsible for causing the accident, that is to say having directly contributed to its occurrence, to drivers involved in an accident for which they were not responsible, and who can be assimilated to drivers in general. The proportion of persons driving under the influence of alcohol is estimated at 2.1% (95% CI: 1.4-2.8) and under the influence of cannabis at 3.4% (2.9%-3.9%). Drivers under the influence of alcohol are 17.8 times (12.1-26.1) more likely to be responsible for a fatal accident, and the proportion of fatal accidents which would be prevented if no drivers ever exceeded the legal limit for alcohol is estimated at 27.7% (26.0%-29.4%). Drivers under the influence of cannabis multiply their risk of being responsible for causing a fatal accident by 1.65 (1.16-2.34), and the proportion of fatal accidents which would be prevented if no drivers ever drove under the influence of cannabis is estimated at 4.2% (3.7%-4.8%). An increased risk linked to opiate use has also been found to be significant, but with low prevalence, requiring caution in interpreting this finding. Other groups of narcotics have even lower prevalence, and the associated extra risks cannot be assessed. Almost a

Ilizarov process is used for the management of multiple fractures, polytrauma conditions, cosmetic limb lengthening, and fracture malunion. Complications associated with the process are nerve palsy, joint contracture, premature or delayed osseous consolidation, a nonunion and permanent stiffness of the joint, pin tract infection, edema, and transient paresthesia, etc. In our case, there was a fatal complication. A 25-year-old African lady underwent the Ilizarov procedure for femur lengthening in a hospital in New Delhi, India. During her first distraction process, she suddenly collapsed at the hospital and could not be revived. At postmortem, a small hematoma was seen around the surgically fractured area. On histopathology of internal organs, fat globules were present in the vasculature of brain and lungs. Cause of death was opined as due to fat embolism. This is the first case reported of a fatal fat embolism following Ilizarov procedure for limb lengthening in a healthy adult. © 2018 American Academy of Forensic Sciences.
Full Text Available This research aims to estimate the relative risks of responsibility for a fatal accident linked to driving under the influence of cannabis or alcohol, the prevalence of these influences among drivers and the corresponding attributable risk ratios. A secondary goal is to estimate the same items for three other groups of illicit drugs (amphetamines, cocaine and opiates, and to compare the results to a similar study carried out in France between 2001 and 2003.Police procedures for fatal accidents in Metropolitan France during 2011 were analyzed and 300 characteristics encoded to provide a database of 4,059 drivers. Information on alcohol and four groups of illicit drugs derived from tests for positivity and potential confirmation through blood analysis. The study compares drivers responsible for causing the accident, that is to say having directly contributed to its occurrence, to drivers involved in an accident for which they were not responsible, and who can be assimilated to drivers in general.The proportion of persons driving under the influence of alcohol is estimated at 2.1% (95% CI: 1.4-2.8 and under the influence of cannabis at 3.4% (2.9%-3.9%.

Full Text Available This article discusses the theme of desire presented in American hard-boiled detective fiction and its subsequent transformation on the screen in form of films noir of the 1940’s. The works in focus are novels The Maltese Falcon by Dashiell Hammett, Farewell, My Lovely by Raymond Chandler and Build My Gallows High by Daniel Mainwaring and their film noir adaptations – The Maltese Falcon (1941, Murder, My Sweet (1944 and Out of the Past (1947. The proposed paper seeks to offer a contrastive analysis of the novels and the films and situate them in their respective social and cultural contexts. The central conflict of this article is presented by the clash between the femme fatale’s and detective’s desires. Hard-boiled novels present femme fatale as a dame with a past, a spider woman, and the detective as a hero with no future, caught in her web of intrigues. The only way out for the detective is to suppress the sexual desire for the woman and hold strong to his professional code. The femme fatale’s desire for more and for better is deadly and dangerous for those who succumb to her lure, but the detective’s desire for truth can be fatal for the dark lady too. This clash presented in the novels is confronted with the 1940’s Hollywood production. When the detective frees himself from the sexual lure of the fatal woman he has a chance to live and even bring her to justice, but she can still escape or decide herself what to do with her destiny. Both, the dame and the hero are victims of their desires. The 1940’s films noir’s femme fatales have to pay for their crimes, no matter how crafty, seductive or manipulative they are. Thus these films present the masculine dominance as strong and undefeated.

We report the case of fatal anthrax meningoencephalitis in the province of Muş located in eastern Anatolia, Turkey. The organism isolated from cerebrospinal fluid was identified as Bacillus anthracis. The patient was treated with crystallized penicillin G (24 MU/day IV) and ciprofloxacin (2 × 400/day IV), but died 5 days after hospitalization. Although it is a rare case, we consider that the patients who have skin, respiratory and neurological systems might also have hemorrhagic meningitis.

Purpose/Objectives: To assess levels of fatalistic beliefs and their association with mammography use in four population groups in Israel.Design: Telephone survey.Setting: Maccabi Healthcare Services in Israel.Sample: A random sample of 1,550 Arabic and Jewish women.Methods: A random telephone survey was performed during May and June 2007. Women's fatalistic beliefs were measured. Information from claims records regarding mammography use was obtained for each woman.Main Research Variables: Levels of fatalistic beliefs and mammography use.Findings: Fatalistic beliefs included general beliefs that God or fate (external force) was the cause of cancer and related to cancer survivorship. The higher-educated women reported less fatalistic beliefs. Arab women reported more fatalistic beliefs compared to the other women. Mammography use was associated with fatalistic beliefs that external forces were the cause of cancer among Arab and immigrant women but not among veteran Jewish and ultraorthodox women. Fatalistic beliefs about cancer survivorship were not associated with mammography in any of the population groups. Levels of fatalism and education may explain the difference in rates of mammography among Arab and Jewish women.Conclusions: High levels of fatalism may inhibit women from having a mammogram, particularly Arab and immigrant women in Israel. However, this is not a generalizable result for all population groups and all types of fatalism.Implications for Nursing: Interventions to decrease fatalism in Arabs and immigrants may increase compliance with mammography. Nurses may achieve this by developing tailored messages for women who believe that external forces are the cause of cancer.

The most important contribution of this research lies in considering the impact of wine, beer and liquors on the ratio of traffic fatalities because each kind of alcoholic beverage is characterized by different ethanol content. The data, drawn for case of Spain, validate our theoretical hypothesis. Our findings support the strategy of incrementing alcohol taxes in order to reduce the negative externalities of alcohol abuse. However, it is necessary to implement non-economic policies because o...

To evaluate animal-caused fatalities in New Mexico using data collected during medicolegal death investigations, including toxicology, survival interval, and circumstances. A retrospective review of the computerized database and hard copies of files from a centralized, statewide medical examiner's office, excluding deaths due to zoonotic diseases and motor vehicle collisions involving animals. Between 1993 and 2004, 63 deaths caused by animals were reported in New Mexico. The majority of decedents were male (46/63, 73%) and non-Hispanic white (33/63, 52%). Horses were the most commonly implicated animals, with 43 (68%) deaths due to a person being thrown from, crushed, dragged, or kicked by a horse. Cattle caused 9 deaths (14%), dogs caused 3 (5%), and venomous animals caused 3, whereas a bear was responsible for 1 death. Ten decedents (16%) had alcohol present at the time of death, and 8 would have been over the legal blood alcohol concentration for driving (0.08%). Ten deaths (16%) were work-related and included deaths of jockeys and ranch workers. The majority of deaths (42/63, 67%) occurred in remote locations, potentially delaying access to treatment. Survival intervals ranged from 1 day to 33 years. Whereas both human and animal behavior can be difficult to predict, a review of animal-caused fatalities investigated by a medical examiner revealed that in many cases, deaths could have been prevented by either the use of protective gear or alterations in human behavior.

The new methods of cannabis consumption (home made water pipe or "bang") may be responsible for fatal respiratory complications. We present a case, with fatal outcome, of a man of 19 years with no previous history other than an addiction to cannabis using "bang". He was admitted to intensive care with acute dyspnoea. A CT scan showed bilateral, diffuse alveolar shadowing. He was anaemic with an Hb of 9.3g/l. Bronchoalveolar lavage revealed massive alveolar haemorrhage. Investigations for infection and immunological disorder were negative and toxicology was negative except for cannabis. Antibiotic treatment was given and favourable progress allowed early discharge. Death occurred 15 days later due to alveolar haemorrhage following a further "bang" of cannabis. Autopsy showed toxic alveolar haemorrhage. The probable mechanism is pulmonary damage due to acid anhydrides released by the incomplete combustion of cannabis in contact with plastic. These acids have a double effect on the lungs: a direct toxicity with severe inflammation of the mucosa leading to alveolar haemorrhage and subsequently the acid anhydrides may lead to the syndrome of intra-alveolar haemorrhage and anaemia described in occupational lung diseases by Herbert in Oxford in 1979. It manifests itself by haemoptysis and intravascular haemolysis. We draw attention to the extremely serious potential consequences of new methods of using cannabis, particularly the use of "bang" in homemade plastic materials. Copyright © 2011 SPLF.

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.

Health researchers struggle to understand barriers to improving health in the African-American community. The African-American church is one of the most promising venues for health promotion, disease prevention, and disparities reduction. Religious fatalism, the belief that health outcomes are inevitable and/or determined by God, may inhibit healthy behaviors for a subset of religious persons. This study reports the development and validation of the Religious Health Fatalism Questionnaire, a measurement tool for studying faith-related health beliefs in African-Americans. Participants included 276 members of seven predominantly African-American churches. Factor analysis indicated three dimensions: (1) Divine Provision; (2) Destined Plan; and (3) Helpless Inevitability. Evidence is presented for the reliability, convergent and predictive validity of the Religious Health Fatalism Questionnaire.

Mexican-American women are disproportionately vulnerable to cardio-metabolic dysfunction and related health conditions such as cardiovascular disease and diabetes. Research shows that low socioeconomic status contributes to this populations excess vulnerability to cardio-metabolic dysfunction, but little is known about the contribution of cultural factors to these associations. The current study explored the association between fatalism and cardio-metabolic dysfunction in a randomly selected community cohort of middle-aged Mexican-American women and examined whether fatalism could be conceptualized as a pathway linking socioeconomic status to cardio-metabolic dysfunction in this population. Participants included 300 women (ages 40-65), recruited from San Diego communities located near the Mexican border, who completed a self-administered survey battery and underwent a fasting clinical exam between the years 2006 and 2009. Linear regression analyses and mediation analyses utilizing bootstrapping procedures were performed to test study hypotheses. After controlling for age, menopausal status, and acculturation level, fatalism was associated with cardio-metabolic dysfunction. Although slightly attenuated, this relationship persisted after accounting for socioeconomic status. In addition, individuals of low socioeconomic status displayed more fatalistic beliefs and higher cardio-metabolic dysfunction after accounting for relevant covariates. Finally, the indirect effect of socioeconomic status on cardio-metabolic dysfunction via fatalism reached statistical significance. Fatalism may be an important independent risk factor for cardio-metabolic dysfunction in Mexican-American women as well as a mechanism linking socioeconomic status to cardio-metabolic health.

Cancer fatalism may impact outcomes, particularly for African American (AA) women with breast cancer (BrCa). We examined the psychometrics of the modified Powe Fatalism Inventory in sample of AA women with BrCa from two studies. Only the predetermination and God's will items satisfy the conditions to be classified as a strong subscale. Our analysis identified that five items had strong psychometric properties for measuring fatalism for AA women with BrCa. However, these items do not include all the defining attributes of fatalism. A strong measure of fatalism strengthens our understanding of how this concept influences AA patient outcomes.

To examine the association between religious fatalism and health care utilization, health behaviors, and chronic illness. As part of Nashville's REACH 2010 project, residents (n=1273) participated in a random telephone survey that included health variables and the helpless inevitability subscale of the Religious Health Fatalism Questionnaire. Religious health fatalism was higher among African Americans and older participants. Some hypotheses about the association between fatalism and health outcomes were confirmed. Religious fatalism is only partially predictive of health behaviors and outcomes and may be a response to chronic illness rather than a contributor to unhealthy behaviors.
Effects of Dietary Approaches to Stop Hypertension (DASH)-style diet on fatal or nonfatal cardiovascular diseases--incidence: a systematic review and meta-analysis on observational prospective studies.

Cardiovascular diseases (CVDs) are a group of disorders affecting heart and blood vessels. However, protective roles are proposed for Dietary Approaches to Stop Hypertension (DASH)-style diets. The aim of this review was to summarize and if possible quantify the longitudinal effects of a DASH-style diet on the incidence of CVDs. Pubmed, ISI web of science, and EMBASE were searched and cohort studies that examined the DASH-style diet in relation to CVDs, coronary heart disease (CHD), stroke, and heart failure (HF) were selected. Cohort studies which included participants with specific CVD risk factors like diabetes mellitus, metabolic syndrome, obesity or hypertension were excluded from review. Relative risks (RRs) that were reported for fully adjusted models and their confidence intervals were extracted for meta-analysis. Regarding the adherence to the DASH diet and the incidence of CVDs, stroke, CHD, and HF, only 6 studies met our criteria to be included in this systematic review. Meta-analysis showed that imitating a DASH-like diet can significantly reduce CVDs (RR = 0.80; 95% confidence interval [CI], 0.74-0.86; P DASH-style diet concordance and all CVDs, as well. In conclusion, our results showed that a DASH-like diet can significantly protect against CVDs, CHD, stroke, and HF risk by 20%, 21%, 19% and 29%, respectively. Furthermore, there is a significant reverse linear association between DASH diet consumption and CVDs, CHD, stroke, and HF risk. Copyright © 2013 Elsevier Inc. All rights reserved.
Full Text Available Abstract Background Ehrlichia chaffeensis is a bacterial pathogen that causes fatal human monocytic ehrlichiosis (HME that mimic toxic shock-like syndrome. Murine studies indicate that over activation of cellular immunity followed by immune suppression plays a central role in mediating tissue injury and organ failure during fatal HME. However, there are no human studies that examine the correlates of resistance or susceptibility to severe and fatal HME. Results In this study, we compared the immune responses in two patients with mild/non fatal and severe/fatal HME who had marked lymphopenia, thrombocytopenia and elevated liver enzymes. The levels of different immunological factors in the blood of those patients were examined and compared to healthy controls. Our data showed that fatal HME is associated with defective production of Th1 cytokines such as ( IFNγ and IL-2, increased anti-inflammatory (IL-10 and IL-13 and pro-inflammatory (TNF-α, IL-1α, IL-1β, and IL-6 cytokines, increased levels of macrophages, T cells, and NK cells chemokines such as MCP-1, MIP-1α, MIP-1β, but not RANTES and IP-10, increased levels of neutrophils chemokine and growth factor (IL-8 and G-CSF, and elevated expression of tumor necrosis factor receptor (TNFR, and toll like receptors 2 and 4 compared to patients with non fatal HME and healthy controls. Conclusions Fatal Ehrlichia-induced toxic shock is associated with defective Th1 responses, possible immune suppression mediated by IL-10. In addition, marked leukopenia observed in patients with fatal disease could be attributed to enhanced apoptosis of leukocytes and/or elevated chemokine production that could promote migration of immune cells to sites of infection causing tissue injury.

Systemic cladosporiosis is described in 25 merino sheep from a flock consisting 250 animals. The fungal pneumonia appeared after an intensive antibiotic treatment, because of a respiratory system disorder. The pen of the flock was humid and crowded, and animals had signs of respiratory distress, coughing, fever and anorexia. All of the ill animals died, and necropsy was performed on 10 sheep. The lesions were characterized by a multifocal pyogranulomatous pneumonia and an abomasitis. Severe hemorrhages were observed in the lungs. At the histopathological examination, severe vasculitis with thrombosis was observed in various organs, especially in the lungs and abomasums, suggestive for a hematogenous dissemination of the infection in these organs. Numerous PAS-positive fungal elements were seen in the pyogranulomatous foci. Dark green fungal colonies were seen in the blood agar and Sabouraud dextrose agar that were identified as Cladosporium cladosporioides. This report highlights that phaeohyphomycosis can cause a severe systemic and fatal disease in merino sheep under insufficient management conditions.

Type 1 herpes simplex virus (HSV-1) is very prevalent yet in rare circumstances can lead to fatal neonatal disease. Genital acquisition of type 2 HSV is the usual mode for neonatal herpes, but HSV-1 transmission by genital or extragenital means may result in greater mortality rates. A very rare scenario is presented in which the mode of transmission was likely through breast lesions. The lesions were seen by nurses as well as the lactation consultant and obstetrician in the hospital after delivery of the affected baby but not recognized as possibly being caused by herpes. The baby died 9 days after birth with hepatic failure and disseminated intravascular coagulation. Peripartum health care workers need to be aware of potential nongenital (including from the breast[s]) neonatal herpes acquisition, which can be lethal. © The Author(s) 2015.

From 1973 through 1978, the Center for Disease Control identified ten deaths caused by ruptured ectopic pregnancy after attempted legal abortions for those pregnancies. The women ranged in age from 18 to 31 years, seven were black, three were white, and five were nulliparous. The estimated gestational age was 16 menstrual weeks or earlier. In seven cases tissue obtained at abortion was sent for outside microscopic pathological examination; attempts to contact four of the patients when no products of conception were found were unsuccessful. An important factor in preventing fatal ectopic pregnancy for women who have legal abortions is the identification of products of conception at the time of the abortion procedure while the patient is still available for reexamination and recurretage.

Background The apparent high number of deaths in Argentina during the 2009 pandemic led to concern that the influenza A H1N1pdm disease was different there. We report the characteristics and risk factors for influenza A H1N1pdm fatalities. Methods We identified laboratory-confirmed influenza A H1N1pdm fatalities occurring during June-July 2009. Physicians abstracted data on age, sex, time of onset of illness, medical history, clinical presentation at admission, laboratory, treatment, and outcomes using standardize questionnaires. We explored the characteristics of fatalities according to their age and risk group. Results Of 332 influenza A H1N1pdm fatalities, 226 (68%) were among persons aged Argentina, though timeliness of antiviral treatment improved during the pandemic. PMID:22506006

Introduction Elephant endotheliotropic herpesvirus-1 (EEHV-1) is one of the major causes of fatality in juvenile Asian elephants (Elephas maximus). On occasions, other EEHV genotypes, i.e. EEHV-3, -4 and -5, have also been reported as the cause of Asian elephant deaths. In this case report we...... describe the investigation into a juvenile Asian elephant fatality in a European zoo. Case Presentation: A fatal case of haemorrhagic disease in a juvenile Asian elephant from a European zoo was diagnosed with co-infection of EEHV-1 and -4. EEHV-4 had a wider organ distribution and a higher viral load......; both viruses presented the highest load in the mesenteric lymph nodes. Conclusion: Detection of EEHV-4 in this fatal case in Europe underlines the importance of inclusion of all known Asian EEHVs in routine blood monitoring to facilitate early therapeutic intervention....
Full Text Available Abstract Introduction Cold agglutinin disease usually develops as a result of the production of a specific immunoglobulin M auto-antibody directed against the I/i and H antigens, precursors of the ABH and Lewis blood group substances, on red blood cells. Autoimmune and lymphoproliferative disorders, Mycoplasma pneumoniae and other infections can be associated with the production of cold agglutinins. In its classic presentation with haemolytic anaemia and Raynaud's syndrome, cold agglutinin disease is usually idiopathic. Several factors play a role in determining the ability of a cold agglutinin to induce a haemolytic anaemia such as antibody concentration and temperature range, in particular the highest temperature at which antibodies interact with red blood cells. Case presentation A 48-year-old Caucasian man presented to our hospital with symptoms of extreme asthenia caused by severe anaemia. The transfusion of red blood cells (O Rh-positive, started as prescribed by the emergency guidelines in force without pre-transfusion tests, induced fatal haemolysis because of the presence of high levels of anti-H antibodies in his blood, that reacted with the large amount of H antigen in universal (0 red blood cells. Conclusion Emergency transfusion of universal red blood cells (0 Rh-positive or negative is usually accepted by the international guidelines in force in emergency departments. In this report we describe a rare complication caused by the very high concentration in the recipient of cold agglutinins and the activation of the complement system, responsible for red blood cell lysis and consequent fatal cardiovascular shock. We conclude that emergency transfusion of universal red blood cells (0 Rh-positive or negative may be dangerous and its risk should be assessed against the risk of delaying transfusion until the pre-transfusion tests are completed.

Anaphylactic reactions to neuromuscular blocking agents (NMBAs) can be severe and even fatal. Our aim was to evaluate mortality rate in France from anaphylactic reactions to NMBAs, to identify risk factors for a fatal outcome, and to describe management of the cases that proved fatal. The French National Pharmacovigilance Database was queried for reports of NMBA anaphylaxis that occurred between January 2000 and December 2011. A questionnaire was sent to regional pharmacovigilance centers to obtain further information on the management of cases with a fatal outcome. Two thousand and twenty-two cases of NMBA hypersensitivity were retrieved, of which 84 were fatal (4.1%). Among the 1247 cases of severe NMBA anaphylaxis (grades 3 and 4), independent risk factors associated with a fatal outcome in a multivariate analysis were male gender (female gender: OR = 0.4; 95% CI 0.2-0.7; P = 0.0004), an emergency setting (OR = 2.6; 95% CI 1.5-4.6; P = 0.0007), a history of hypertension (OR = 2.5; 95% CI 1.5-4.4; P = 0.0010) or of other cardiovascular disease (OR = 4.4; 95% CI 2.4-8.1; P < 0.0001), obesity (OR = 2.4; 95% CI 1.1-5.3; P = 0.0376), and ongoing beta-blocker treatment (OR = 4.2; 95% CI 1.8-9.8; P = 0.0011). All 31 patients with a fatal outcome received epinephrine in a titrated manner according to international guidelines. Obese males with a history of cardiovascular disease receiving ongoing beta-blocker treatment and undergoing surgery in an emergency setting were at high risk of a fatal outcome after NMBA-induced anaphylaxis. Some epinephrine-resistant cases may play a role in our high mortality rate. New therapeutic approaches need to be developed to treat these cases. © 2014 John Wiley & Sons A/S.

The EORTC-NCIC regimen for glioblastoma requires different dosing of temozolomide (TMZ) during radiation and maintenance therapy. This complexity is exacerbated by the availability of multiple TMZ capsule strengths. TMZ is an alkylating agent and the major toxicity of this class is dose-related myelosuppression. Inadvertent overdose can be fatal. The websites of the Institute for Safe Medication Practices (ISMP), and the Food and Drug Administration (FDA) MedWatch database were reviewed. We searched the MedWatch database for adverse events associated with TMZ and obtained all reports including hematologic toxicity submitted from 1st November 1997 to 30th May 2012. The ISMP describes errors with TMZ resulting from the positioning of information on the label of the commercial product. The strength and quantity of capsules on the label were in close proximity to each other, and this has been changed by the manufacturer. MedWatch identified 45 medication errors. Patient errors were the most common, accounting for 21 or 47% of errors, followed by dispensing errors, which accounted for 13 or 29%. Seven reports or 16% were errors in the prescribing of TMZ. Reported outcomes ranged from reversible hematological adverse events (13%), to hospitalization for other adverse events (13%) or death (18%). Four error reports lacked detail and could not be categorized. Although the FDA issued a warning in 2003 regarding fatal medication errors and the product label warns of overdosing, errors in TMZ dosing occur for various reasons and involve both healthcare professionals and patients. Overdosing errors can be fatal.

Full Text Available Taking advantage of an interesting clinical scenario, we want to introduce a discussion about fatality in our daily practice and the need to accept that. An 80 year-old man with non-traumatic spontaneous bleeding tendency came to the clinics. Although being on warfarin as a consequence of primary thrombotic prophylaxis due to an atrial fibrillation, full assessment was performed. Not only the rare entity found on him, but also the severe complication that happened afterwards challenged clinicians and led them to risky treatment options.

Serotonin syndrome (SS) is a complication after overdosage with antidepressants. SS increases the level of circulating serotonin. Fatal outcome of SS is most often seen in cases where there has been an overdosage with selective serotonin reuptake inhibitors (SSRI)/selective noradrenaline reuptake inhibitors (SNRI) in combination with other serotonin increasing drugs. This case report describes the rapid development of symptoms in a 54-year-old man who ingested a total amount of 6.5 g of SSRI and SNRI drugs as the only drug types. It proves the importance of being aware of the symptoms of SS when the patient is first seen in the emergency department.
Full Text Available BACKGROUND: Circulating inflammatory markers may more strongly relate to risk of fatal versus nonfatal cardiovascular disease (CVD events, but robust prospective evidence is lacking. We tested whether interleukin (IL-6, C-reactive protein (CRP, and fibrinogen more strongly associate with fatal compared to nonfatal myocardial infarction (MI and stroke. METHODS AND FINDINGS: In the Prospective Study of Pravastatin in the Elderly at Risk (PROSPER, baseline inflammatory markers in up to 5,680 men and women aged 70-82 y were related to risk for endpoints; nonfatal CVD (i.e., nonfatal MI and nonfatal stroke [n = 672], fatal CVD (n = 190, death from other CV causes (n = 38, and non-CVD mortality (n = 300, over 3.2-y follow-up. Elevations in baseline IL-6 levels were significantly (p = 0.0009; competing risks model analysis more strongly associated with fatal CVD (hazard ratio [HR] for 1 log unit increase in IL-6 1.75, 95% confidence interval [CI] 1.44-2.12 than with risk of nonfatal CVD (1.17, 95% CI 1.04-1.31, in analyses adjusted for treatment allocation. The findings were consistent in a fully adjusted model. These broad trends were similar for CRP and, to a lesser extent, for fibrinogen. The results were also similar in placebo and statin recipients (i.e., no interaction. The C-statistic for fatal CVD using traditional risk factors was significantly (+0.017; p<0.0001 improved by inclusion of IL-6 but not so for nonfatal CVD events (p = 0.20. CONCLUSIONS: In PROSPER, inflammatory markers, in particular IL-6 and CRP, are more strongly associated with risk of fatal vascular events than nonfatal vascular events. These novel observations may have important implications for better understanding aetiology of CVD mortality, and have potential clinical relevance.

Poisoning is a worldwide problem that involves individuals of all ages and a range of chemicals. In this study, fatal poisoning cases that occurred in the Federal District of Brazil (DF) from 2009 to 2013 were described using information from four systems, and the reasons for underreporting of each system were discussed. Data were obtained from the mortality information system (SIM), the notifiable disease information system (SINAN), the poison information center (CIT), and the forensic medicine institute (IML) of the DF. In total, 288 cases were reported to SIM, 18 to SINAN, 29 to CIT and 101 cases identified in the IML. SIM data indicated a prevalence of 2.24 cases/year/100,000 individuals in the DF, higher than the national estimation (1.36). After eliminating the 98 duplicate cases among the systems, 338 fatal unique cases were identified, from which 74.0% were reported in only one system (mainly the SIM), 23.4% in two systems, 8 cases in three systems and only 1 case was reported in the four systems. Over two thirds of the 338 fatalities involved men (67.4%), and 46.9% involved individuals aged 20-39 years. Medications were the main agent involved (49.4%), followed by pesticides (29.9%). The fatalities occurred mainly after unintentional exposure (50.8%) and suicide (47.7%, of which 53.5% involved pesticides). These results confirmed the previous hypothesis that none of the information systems could capture the whole picture of fatal poisonings in the DF. Underreporting was found in all systems, indicating the need to improve the information quality and the coordination of data reporting, so that health authorities can better understand and reduce these fatalities.

Reverse hanging (also known as Palestinian hanging) is a form of positional torture where the victim is suspended for a prolonged period of time by the wrists, after the wrists are bound at the back. We report the first autopsy case of reverse hanging. We have discovered that fatal myoglobinuric renal failure due to rhabdomyolysis can be a complication of Palestinian hanging. An adult detainee, who underwent interrogation by authorities, was admitted to hospital from a prison and died in hospital after a few days. Death was due to myoglobinuric renal failure. An autopsy was performed. At autopsy, the body showed anasarca due to renal failure. There were healing ligature marks on the wrist and forearm, but no blunt impact injury to the shoulders or arms. There was extensive necrosis of the pectoralis major, biceps, and deltoid muscles, organizing hemoarthrosis of the right glenohumeral joint and hemorrhage into the joint capsule of the both glenohumeral joints. The kidneys showed evidence of myoglobin deposition grossly. The overstretching of the major muscles of the shoulder, in response to the prolonged Palestinian hanging, gave rise to the muscle necrosis. This case underscores the importance of conducting autopsies on people who die in custody, particularly if detained at times of political instability when torture may be practiced by state actors and others. This case also reveals that fatal rhabdomyolysis can occur by positional torture in a stress position, despite the absence of direct trauma due to blunt impacts.

To compare the risk of fatal injury across helmet types among collision-involved motorcyclists. We used data from a cohort of motorcyclists involved in police-reported traffic collisions. Eighty-four law enforcement agencies in California collected detailed information on helmet and rider characteristics during collision investigations in June 2012 through July 2013. Multiply-adjusted risk ratios were estimated with log-binomial regression. The adjusted fatal injury risk ratio for novelty helmets was 1.95 (95% CI 1.11-3.40, p 0.019), comparing novelty helmets with full-face helmets. The risk ratios for modular, open-face, and half-helmets, compared with full-face helmets, were not significant. A more complete understanding of the inadequacy of novelty helmets can be used in educational and law enforcement countermeasures to improve helmet use among motorcycling populations in California and other US states. Law enforcement approaches to mitigating novelty helmet use would seem attractive given that novelty helmets can be visually identified by law enforcement officers with sufficient training.

Fatal hydrogen sulphide poisoning usually occurs in confined spaces. We report two fatal accidents in unconfined spaces. The first accident caused the death of three workers who entered an unconfined room in a silo of sludge at the same time that a truck dumped several tons of sludge from water purification stations. The hydrogen sulphide that had accumulated inside the silo spilled out into the interior of the room due to a 'splashing effect' caused by the impact of the dumped sludge. The second accident occurred when the foreman of a wastewater treatment plant entered one of the substations to perform routine checks and suddenly lost consciousness. Although he was rapidly transferred to an intensive care unit, death occurred a few hours later. Hydrogen sulphide production was, in this case, due to an 'embolism effect' produced by the displacement of wastewater when the substation pumps were activated. We suggest ways in which accidents such as these caused by sudden release of hydrogen sulphide can be prevented.

Pontine vascular malformations have usually been found at autopsy as an incidental finding or as a cause of a fatal hemorrhage. In recent years, however, computerized tomography (CT) has made it possible to visualize these lesions while the patinents are still alive. In this paper, we report 2 cases with non-fatal hemorrhages from pontine vascular malformation. The first case was a 31-year-old housewife with cheif complaints of a sensory disturbance of the left half of the body, double vision, nausea, and vomiting of 2 weeks' duration. CT revealed a small high-density mass, which was partially slightly contrast-enhanced, in the right lower pontine tegmentum, affecting the medial and lateral lemnisci, abducens, facial and acoustic nerves, brachium pontis, medial longitudinal fasciculus, corticospinal and corticobulbar fibers, and parepontine reticular formation. The second case was a 52-year-old female clerk with chief complaints of a sensory disturbance of the right half of the body and gait disturbance of 7 months' duration. CT revealed a small high-density mass, which was partially contrast-enhanced, in the left midpontine tegmentum, affecting the medial and lateral lemnisci, lateral spinothalamic tract, ventral ascending tract of V, and brachium pontis. Although there was no evidence of subarachnoid hemorrhage, both cases were deterirating progressively, probably due to tepeated small intraparenchymal hemorrhages. They were treated by radiation therapy in order to prevent further rebleeding. Fortunately, their symptoms gradually subsided, and both of them were doing well 2 years and one and a half years respectively after radiation therapy. The value of radiation therapy for this disease entity has not yet been established, but it may be worthwhile when the symptoms are worsening and there is no other suitable treatment. (J.P.N.)

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.

Background The prognosis, specifically the case fatality and duration, of untreated tuberculosis is important as many patients are not correctly diagnosed and therefore receive inadequate or no treatment. Furthermore, duration and case fatality of tuberculosis are key parameters in interpreting epidemiological data. Methodology and Principal Findings To estimate the duration and case fatality of untreated pulmonary tuberculosis in HIV negative patients we reviewed studies from the pre-chemotherapy era. Untreated smear-positive tuberculosis among HIV negative individuals has a 10-year case fatality variously reported between 53% and 86%, with a weighted mean of 70%. Ten-year case fatality of culture-positive smear-negative tuberculosis was nowhere reported directly but can be indirectly estimated to be approximately 20%. The duration of tuberculosis from onset to cure or death is approximately 3 years and appears to be similar for smear-positive and smear-negative tuberculosis. Conclusions Current models of untreated tuberculosis that assume a total duration of 2 years until self-cure or death underestimate the duration of disease by about one year, but their case fatality estimates of 70% for smear-positive and 20% for culture-positive smear-negative tuberculosis appear to be satisfactory.

A fatal case of nicotine poisoning is reported in which a 44-year-old female committed suicide in a short time by taking orally the eluate from tobacco. External examination showed no abnormal findings except for markedly dark red-purple postmortem lividity, and internal examination demonstrated no pathological changes but the signs of sudden death. Through the toxicological investigation by GC and GC-MS, however, nicotine was detected in the solution which she had taken orally and in the blood, urine and the contents of the stomach and small intestine. The nicotine concentrations of the blood, urine and contents of stomach and small intestine were 6.3 micrograms/ml, 1.5 micrograms/ml, 30 micrograms/ml and 71 micrograms/g respectively, and enough to be lethal.

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.

Shopping carts may be associated with a variety of injuries, particularly in toddlers and young children. These usually relate to falls from carts or to tip-overs. Injuries that are sustained include hematomas/contusions, abrasions, lacerations, fractures, and fingertip amputations. Fatal episodes are uncommon and are usually due to blunt craniocerebral trauma from falls. A case involving a 19-month-old girl is reported who became entrapped when she inserted her head through the side frame of a cart that had been removed from a supermarket and left at her home address. Death was caused by neck compression. Although rare, the potential for lethal entrapment during unsupervised play means that the presence of stray shopping carts at private residences and in public places, including playgrounds and parks, is of concern. Strategies, such as coin deposits, should be encouraged to assist in the return of such carts to supermarkets.

Metabolic and toxicological data were obtained during the first 24 hours following severe and eventually fatal cyanide poisoning. Initial blood cyanide concentrations were 804 mumol/l but fell rapidly over 24 hours following cobalt edetate therapy to 15 mumol/l. However, plasma thiocyanate concentrations rose over 24 hours (147-267 mumol/l) suggesting continued tissue detoxification. The major metabolic abnormality was lactic acidosis (initial pH 7.21, blood lactate 17.5 mmol/l) which corrected over 12 hours. Despite high circulating insulin concentrations the responses of blood glucose, plasma non-esterified fatty acid, blood glycerol and 3-hydroxybutyrate suggested marked insulin resistance.

Two captive tiger attacks are presented that took place in Cologne and Münster zoos. Both attacks occurred when the handlers, intent on cleaning the enclosures, entered whilst the tigers accidently retained access to the location, and thus defended their territory against the perceived intruders. Both victims suffered fatal neck injuries from the bites. At Münster, colleagues managed to lure the tiger away from its victim to enable treatment, whilst the Cologne zoo tiger had to be shot in order to allow access to be gained. Whilst it was judged that human error led to the deaths of the experienced zookeepers, the investigation in Münster was closed as no third party was found to be at fault, whereas the Cologne zoo director was initially charged with being negligent. These charges were subsequently dismissed as safety regulations were found to be up to date.

Little is known about the correlates of cancer information avoidance and whether people with negative feelings and beliefs about cancer are more likely to avoid cancer information, allowing such thoughts and feelings to persist unchallenged. Using the Extended Parallel Processing Model as a theoretical guide, we tested the hypothesis that cancer fear and fatalism would predict cancer information avoidance but that part of this effect would be mediated via cancer-specific threat and efficacy beliefs. A community sample of older adults, ages 50 to 70 years (n = 1,442), completed a postal questionnaire that included the Powe Fatalism Inventory and the Champion Cancer Fear scale along with other measures of cancer-specific beliefs and demographic variables. Higher levels of cancer fear were positively associated with higher levels of cancer information avoidance, and part of this relationship was mediated via perceived cancer severity. The relationship between cancer fatalism and cancer information avoidance was partly mediated by severity and response-efficacy beliefs. This research shows that people with negative views about cancer are more likely to avoid cancer information. This means people with higher levels of cancer fear and fatalism are less likely to learn about positive developments made in the field of cancer control, allowing such negative feelings and views to continue. Research needs to focus on how to get positive messages about improvements in cancer prevention and control through to people who are fearful of and fatalistic about the disease.

To accurately describe patient characteristics and the clinical presentation of fatal colloid cysts. A systematic literature search of 3 popular databases was performed. Inclusion criteria were individuals with sudden-onset death and colloid cysts identified on imaging and/or autopsy. The cause of death must have been ascribed to the colloid cyst to be eligible for data extraction. Deaths precipitated by lumbar puncture were excluded. Clinical data were extracted and descriptive statistics were ascertained. Subgroup analyses were performed to compare adults with pediatric patients. A total of 107 patients were included in the quantitative synthesis. The mean age was 28.5 years (standard deviation 13.3, range 6-79 years). Male and female patients were affected equally. Headache was the most frequent symptom (n = 86, 80%). There were 6 patients (5 adults and 1 child) who reported positional headaches. The mean duration of signs and symptoms was shorter in adults versus pediatric patients (2.1 days vs. 6.5 days, P = 0.02), and more adults presented with signs and symptoms for less than 24 hours than did pediatric patients (38% vs. 6%, P = 0.01). Colloid cyst mean diameter was 2.0 cm (standard deviation 1.1, range 0.5-7.9 cm) and 96% measured 1 cm or larger. Our data suggests that the prodrome preceding sudden death in the setting of a colloid cyst may be shorter in adults. Also, most fatal colloid cysts measured 1 cm or larger. Copyright © 2017.

Although a goal of disaster preparedness is to protect vulnerable populations from hazards, little research has explored the types of risks that workers face in their encounters with natural disasters. This study examines how workers are fatally injured in severe natural events. A classification structure was created that identified the physical component of the disaster that led to the death and the pursuit of the worker as it relates to the disaster. Data on natural disasters from the Census of Fatal Occupational Injuries for the years 1992 through 2006 were analyzed. A total of 307 natural disaster deaths to workers were identified in 1992-2006. Most fatal occupational injuries were related to wildfires (80 fatalities), hurricanes (72 fatalities), and floods (62 fatalities). Compared with fatal occupational injuries in general, natural disaster fatalities involved more workers who were white and more workers who were working for the government. Most wildfire fatalities stemmed directly from exposure to fire and gases and occurred to those engaged in firefighting, whereas hurricane fatalities tended to occur more independently of disaster-produced hazards and to workers engaged in cleanup and reconstruction. Those deaths related to the 2005 hurricanes occurred a median of 36.5 days after landfall of the associated storm. Nearly half of the flood deaths occurred to passengers in motor vehicles. Other disasters included tornadoes (33 fatalities), landslides (17), avalanches (16), ice storms (14), and blizzards (9). Despite an increasing social emphasis on disaster preparation and response, there has been little increase in expert knowledge about how people actually perish in these large-scale events. Using a 2-way classification structure, this study identifies areas of emphasis in preventing occupational deaths from various natural disasters.

Full Text Available Abstract Cryptococcus neoformans is the most common cause of life threatening meningoencephalitis in HIV-infected patients. Diagnosis is based on tests for cryptoccocal antigen in serum and cerebrospinal fluid, and on culture of the organism. We present a case of AIDS-related cryptococcal meningoencephalitis unresponsive to antifungal combination therapy, despite of evidence of fungal susceptibility in vitro. Significant decreases in cryptococcal antigen titers in serum and cerebrospinal fluid did not correlate with progress in disease and fatal outcome.
Full Text Available Two confirmed cases of fatal disseminated toxoplasmosis occurred in an urban zoological collection of meerkats (Suricata suricatta. Both cases are suspected to be the result of feral cats gaining access to the enclosure. Toxoplasmosis has rarely been documented in meerkats. Subsequent to prophylactic treatment of all the animals and structural changes being implemented within the enclosure, no new cases have been recorded to date. Very little information is available on the disease in viverrids.

Fatal familial insomnia (FFI) is a rare hereditary human prion disease with unique clinical features including progressive sleep impairment and autonomic dysfunction. The serotonergic system is considered to be involved in the regulation of the sleep-wake cycle. In this study we demonstrate a reduced availability of serotonin transporters of 57 % and 73 % respectively in a thalamus-hypothalamus region of two FFI patients examined with β-CIT SPECT as compared to age-expected control values.

This study describes the nature and extent of fatal heavy vehicle driver crashes in Victoria between 1999 and 2007 and the factors associated with the crash. A descriptive study was conducted comprising the population of heavy vehicle drivers killed in a road transport crash while operating a vehicle of > or =4.5 tonne Gross Vehicle Mass (GVM) for the purposes of work. Information about the nature of crash, environmental, driver, vehicle and occupational factors were collected from the coroner's death investigation file. Of the 91 deaths identified 61 were eligible for review. All 61 cases were male, solo drivers with a mean age of 44.7 years. Most vehicles were articulated in configuration. One-third of crash scenarios involved a single vehicle leaving the roadway on a straight road. One in every six fatally injured drivers was detected with the presence of stimulants or cannabis. Twenty-two drivers were travelling at excessive or inappropriate speeds for the circumstances. Seatbelt wearing status was documented for only 25 of 61 drivers. This study is the first to comprehensively examine a population of fatally injured heavy vehicle drivers using coroner's investigation files and these findings are consistent with previous, less detailed, Australian research. Information about potential associations between occupational factors and crash risk was limited. Improving driver safety requires incorporation of occupational factors into a standardised approach to heavy vehicle crash investigations.

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.

Mosquito-borne alphaviruses are important causes of epidemic encephalomyelitis. Neuronal cell death during fatal alphavirus encephalomyelitis is immune-mediated; however, the types of cells involved and their regulation have not been determined. We show that the virus-induced inflammatory response was accompanied by production of the regulatory cytokine IL-10, and in the absence of IL-10, paralytic disease occurred earlier and mice died faster. To determine the reason for accelerated disease in the absence of IL-10, immune responses in the CNS of IL-10(-/-) and wild-type (WT) mice were compared. There were no differences in the amounts of brain inflammation or peak virus replication; however, IL-10(-/-) animals had accelerated and increased infiltration of CD4(+)IL-17A(+) and CD4(+)IL-17A(+)IFNγ(+) cells compared with WT animals. Th17 cells infiltrating the brain demonstrated a pathogenic phenotype with the expression of the transcription factor, Tbet, and the production of granzyme B, IL-22, and GM-CSF, with greater production of GM-CSF in IL-10(-/-) mice. Therefore, in fatal alphavirus encephalomyelitis, pathogenic Th17 cells enter the CNS at the onset of neurologic disease and, in the absence of IL-10, appear earlier, develop into Th1/Th17 cells more often, and have greater production of GM-CSF. This study demonstrates a role for pathogenic Th17 cells in fatal viral encephalitis.
Full Text Available Abstract Background Acute poisonings are common and are treated at different levels of the health care system. Since most fatal poisonings occur outside hospital, these must be included when studying characteristics of such deaths. The pattern of toxic agents differs between fatal and non-fatal poisonings. By including all poisoning episodes, cause-fatality rates can be calculated. Methods Fatal and non-fatal acute poisonings in subjects aged ≥16 years in Oslo (428 198 inhabitants were included consecutively in an observational multi-centre study including the ambulance services, the Oslo Emergency Ward (outpatient clinic, and hospitals, as well as medico-legal autopsies from 1st April 2003 to 31st March 2004. Characteristics of fatal poisonings were examined, and a comparison of toxic agents was made between fatal and non-fatal acute poisoning. Results In Oslo, during the one-year period studied, 103 subjects aged ≥16 years died of acute poisoning. The annual mortality rate was 24 per 100 000. The male-female ratio was 2:1, and the mean age was 44 years (range 19-86 years. In 92 cases (89%, death occurred outside hospital. The main toxic agents were opiates or opioids (65% of cases, followed by ethanol (9%, tricyclic anti-depressants (TCAs (4%, benzodiazepines (4%, and zopiclone (4%. Seventy-one (69% were evaluated as accidental deaths and 32 (31% as suicides. In 70% of all cases, and in 34% of suicides, the deceased was classified as drug or alcohol dependent. When compared with the 2981 non-fatal acute poisonings registered during the study period, the case fatality rate was 3% (95% C.I., 0.03-0.04.

Acute poisonings are common and are treated at different levels of the health care system. Since most fatal poisonings occur outside hospital, these must be included when studying characteristics of such deaths. The pattern of toxic agents differs between fatal and non-fatal poisonings. By including all poisoning episodes, cause-fatality rates can be calculated. Fatal and non-fatal acute poisonings in subjects aged > or =16 years in Oslo (428 198 inhabitants) were included consecutively in an observational multi-centre study including the ambulance services, the Oslo Emergency Ward (outpatient clinic), and hospitals, as well as medico-legal autopsies from 1st April 2003 to 31st March 2004. Characteristics of fatal poisonings were examined, and a comparison of toxic agents was made between fatal and non-fatal acute poisoning. In Oslo, during the one-year period studied, 103 subjects aged > or =16 years died of acute poisoning. The annual mortality rate was 24 per 100 000. The male-female ratio was 2:1, and the mean age was 44 years (range 19-86 years). In 92 cases (89%), death occurred outside hospital. The main toxic agents were opiates or opioids (65% of cases), followed by ethanol (9%), tricyclic anti-depressants (TCAs) (4%), benzodiazepines (4%), and zopiclone (4%). Seventy-one (69%) were evaluated as accidental deaths and 32 (31%) as suicides. In 70% of all cases, and in 34% of suicides, the deceased was classified as drug or alcohol dependent. When compared with the 2981 non-fatal acute poisonings registered during the study period, the case fatality rate was 3% (95% C.I., 0.03-0.04). Methanol, TCAs, and antihistamines had the highest case fatality rates; 33% (95% C.I., 0.008-0.91), 14% (95% C.I., 0.04-0.33), and 10% (95% C.I., 0.02-0.27), respectively. Three per cent of all acute poisonings were fatal, and nine out of ten deaths by acute poisonings occurred outside hospital. Two-thirds were evaluated as accidental deaths.

The purpose of the study was to study the circumstances and incidence rates of fatal accidents in inspection obligated and non-inspection obligated Danish fishing vessels to identify areas for prevention. Information about the fatalities came from maritime authority reports, including vessel...... disaster reports, post mortem reports, maritime inquiries and police reports. The person- and vessel years at risk came from the Danish Directorate of Fisheries. During the period 1989-2005, 114 fatalities occurred. Sixty-one of the fatalities occurred in 36 vessel disasters mainly caused by foundering...... in foreign ports and alcohol intoxication. In the period 1995-2005, the overall incidence rate was 10 per 10,000 fishermen per year with no down-going trend during that period. The fatal accident rates are still too high, despite the efforts to reduce the risk. Increased focus on regular and repeated safety...

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. Copyright © 2010 Elsevier Ltd. All rights reserved.

Background Mexican-American women are disproportionately vulnerable to cardio-metabolic dysfunction and related health conditions such as cardiovascular disease and diabetes. Research shows that low socioeconomic status contributes to this populations excess vulnerability to cardio-metabolic dysfunction, but little is known about the contribution of cultural factors to these associations. Purpose The current study explored the association between fatalism and cardio-metabolic dysfunction in a randomly selected community cohort of middle-aged Mexican–American women and examined whether fatalism could be conceptualized as a pathway linking socioeconomic status to cardio-metabolic dysfunction in this population. Method Participants included 300 women (ages 40–65), recruited from San Diego communities located near the Mexican border, who completed a self-administered survey battery and underwent a fasting clinical exam between the years 2006 and 2009. Results Linear regression analyses and mediation analyses utilizing bootstrapping procedures were performed to test study hypotheses. After controlling for age, menopausal status, and acculturation level, fatalism was associated with cardio-metabolic dysfunction. Although slightly attenuated, this relationship persisted after accounting for socioeconomic status. In addition, individuals of low socioeconomic status displayed more fatalistic beliefs and higher cardio-metabolic dysfunction after accounting for relevant covariates. Finally, the indirect effect of socioeconomic status on cardio-metabolic dysfunction via fatalism reached statistical significance. Conclusions Fatalism may be an important independent risk factor for cardio-metabolic dysfunction in Mexican–American women as well as a mechanism linking socioeconomic status to cardio-metabolic health.

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. PMID:27339481

Fatalities in football are rare but tragic events. The purpose was to describe the causes of fatalities in high school and college football players and potentially provide preventive strategies. Descriptive epidemiology study. We reviewed the 243 football fatalities reported to the National Center for Catastrophic Sports Injury Research from July 1990 through June 2010. Football fatalities averaged 12.2 per year, or 1 per 100,000 participants. There were 164 indirect (systemic) fatalities (average, 8.2 annually [or 0.7 per 100,000 participants]) and 79 direct (traumatic) fatalities (average, 4.0 annually [or 0.3 per 100,000 participants]). Indirect fatalities were 2.1 times more common than direct fatalities. The risk of a fatality in college compared with high school football players was 2.8 (95% CI, 0.7-8.2) times higher for all fatalities, 3.6 (95% CI, 2.5-5.3) times higher for indirect events, 1.4 (95% CI, 0.6-3.0) times higher for direct injuries, 3.8 (95% CI, 1.8-8.3) times higher for heat illness, and 66 (95% CI, 14.4-308) times higher for sickle cell trait (SCT) fatalities. Most indirect events occurred in practice sessions; preseason practices and intense conditioning sessions were vulnerable periods for athletes to develop heat illness or SCT fatalities, respectively. In contrast, most brain fatalities occurred during games. The odds of a fatality during the second decade, compared with the first decade of the study, were 9.7 (95% CI, 1.2-75.9) for SCT, 1.5 (95% CI, 0.8-2.9) for heat illness, 1.1 (95% CI, 0.8-1.7) for cardiac fatalities, and 0.7 (95% CI, 0.4-1.2) for brain fatalities. The most common causes of fatalities were cardiac failure (n = 100, 41.2%), brain injury (n = 62, 25.5%), heat illness (n = 38, 15.6%), SCT (n = 11, 4.5%), asthma and commotio cordis (n = 7 each, 2.9% each), embolism/blood clot (n = 5, 2.1%), cervical fracture (n = 4, 1.7%), and intra-abdominal injury, infection, and lightning (n = 3, 1.2% each).

Three suicides and one homicide from black powder muzzle loading handguns are reported and the muzzle velocities of two weapons are recorded. The fatal head shots caused wide wound tracts traversing the brains and intracerebral haemorrhages remote from the tract were present in every case. The skulls showed considerable fractures which were pronounced in the cases of contact shots but were also present when the range of fire was 5 m. These extensive injuries from soft lead spheres with muzzle velocities of only approximately 200 m/s are attributed to the expansion of the spheres. The regularly occurring deformation resulted in 13-16 mm calibre missiles in the cases of .44 spheres. The special features of black powder such as incomplete and slow combustion resulted in intense soot deposits in the vicinity of the entrance wound and in long ranges the gunshot residues travelled. In contact shots, large pocket-like underminings even in deeper tissue layers, abundant soot along the trajectory and skin burns were observed.

The sand cat (Felis margarita) is a small-sized felid occurring in the United Arab Emirates (UAE). The sand cat captive-breeding program at the Breeding Centre for Endangered Arabian Wildlife in Sharjah, UAE, has until recently been severely compromised by very high newborn mortality rates. Two different pairs of sand cats gave birth, respectively, to one and two litters (with a total of eight kittens) between 1999 and 2006. Seven out of eight kittens died between the third and 21st wk of life. Toxoplasmosis was confirmed as the cause of death in these two litters. Adult cats had high antibody titers to Toxoplasma gondii before pregnancy, suggesting that maternal immunity did not protect the kittens against infection with T. gondii and that maternal immunity might not have prevented transplacental transmission of the parasite. This observation contrasts with what is seen in domestic cats. To date, this is the first report on confirmed fatal toxoplasmosis and prevalence of T. gondii in sand cats.

Full Text Available The author makes here an analysis of Friedrick A. Hayek's The Fatal Conceit. This thinker considers that the best political-economical system for human civilization is capitalism, which has arised in an spontaneous, evolutive and adaptative way without any intention or plan thanks to a deus ex machina. Hayek shows himself as an advocate of capitalism and as an enemy of socialism; he despises solidarity and supports egoism as the motor of economy, for, according to him, without it society would not be where it is now. Hayek imports Darwin's evolutionary theory in order to justify economy's blind and fortuitous development, which in turn explains that capitalism is reached through a series of unforeseen and spontaneous events which are overcomed thanks to adaptation. Hayek draws historicist arguments at some poins, in an invalid way, rejecting everything that looks like socialism, and he makes mistakes where philosophical concepts are dealed with. Hayek's continuous reject towards Aristotle and his political-economical thesis obeys to the fact that the author rejects the Catholic Church, which, according to him, gathered the Aristotelian thesis through saint Thomas Aquinas. Hayek proposes a selfish and capitalist moral which one ought to accept if one does not wish for hunger and poverty.

We report a case of recurrent post-partum pyoderma gangrenosum (PG) complicated by post-partum cardiomyopathy (PPCM). A 23-year-old woman presented with a previous medical history of aseptic abscess of the left breast in her fourth pregnancy, which developed after surgical drainage of an inflammatory ulceration treated by atraumatic topical care. During her fifth pregnancy, the patient presented a large and painful ulceration in relation to the scar of the Caesarean section, despite the introduction of broad-spectrum antibiotic therapy. Bacteriological samples were negative. Histological examination militated in favor of PG. One week after initiation of corticosteroid therapy, the patient suddenly showed signs of heart failure. Based on trans-thoracic echocardiography PPCM was diagnosed, and the outcome was fatal. This observation raises the question of the relationship between PG and pregnancy and describes the association of PG and PPCM. PG occurs rarely during pregnancy and it may be induced by the rise in G-CSF levels found in pregnant women. The association with PPCM seen in our patient could have been due to the development of an anti-angiogenic climate at the end of pregnancy, together with inflammatory myocardial aggression linked to the PG.

Full Text Available Introduction. ‘Body packer’ syndrome with severe intoxication or sudden death may happen in persons who smuggle drugs in their body cavities. In case of lethal outcome when carrying cocaine, it is important, but sometimes difficult to determine whether death was due to intoxication or due to other causes. Therefore, it is necessary not only to quantify cocaine and its metabolites in biological material, but also based on their distribution in body fluids and tissues to conclude whether it is acute intoxication. We described a well-documented case of fatal poisoning in a body packer and post mortem distribution of the drug in biological samples. Case report. A 26-year-old man was brought to hospital with no vital signs. Resuscitation measures started at once, but with no success. Autopsy revealed 66 packets of cocaine in his digestive tract, one of which was ruptured. Hyperemia of the most of all internal organs and pulmonary and brain edema were found. High concentrations of cocaine, its metabolites benzoylecgonine and ecgonine methyl ester, as well as cocaine adulteration levamisole were proven in the post mortem blood and tissues by liquid chromatography-mass spectrometry (LC-MC method with selective-ion monitoring. Conclusion. The ratio of cocaine and its metabolites concentrations in the brain and blood obtained by LC-MS method can be used for forensic confirmation of acute intoxication with cocaine.

To determine the economic costs associated with all quad bike-related fatalities in Australia, 2001 to 2010. A human capital approach to establish the economic costs of quad bike related fatalities to the Australian economy. The model included estimates on loss of earnings due to premature death and direct costs based on coronial records for ambulance, police, hospital, premature funeral, coronial and work safety authority investigation, and death compensation costs. All costs were calculated to 2010 dollars. The estimated total economic cost associated with quad bike fatalities over this period was $288.1 million, with an average cost for each fatality of $2.3 million. When assessing the average cost of incidents between age cohorts, those aged 25-34 years had the lowest number of fatalities but had the highest average cost ($4.2 million). Quad bike fatalities have a significant economic impact on Australian society that is increasing. Implications : Given the high cost to society, interventions to address quad bike fatalities have the potential to be highly cost-effective. Such interventions should focus on design approaches to improve the safety of quad bikes in terms of stability and protection in the event of a rollover. Additionally, relevant policy (e.g. no children under 16 years riding quads, no passengers) and intervention approaches (e.g. training and use of helmets) must also support the design modifications. © 2013 The Authors.

Fatalistic beliefs about cancer have been implicated in low uptake of screening and delay in presentation particularly in low socioeconomic status (SES) groups, but no studies have systematically evaluated interrelationships between SES, fatalism, and early detection behaviors. We explored whether (i) fatalism is associated with negative attitudes toward early detection, (ii) lower SES groups are more fatalistic, and (iii) SES differences in fatalism partly explain SES differences in attitudes toward early detection. In a population-representative sample of adults in Britain using computer-based interviews in the home setting, respondents (N = 2,018) answered two questions to index fatalism (expectations of cancer survival and cure) and two items on early detection attitudes (the perceived value of early detection and fear of symptom reporting). SES was indexed with a social grade classification. Fatalism was associated with being less positive about early detection (β = -0.40, P fatalism might explain SES differences in attitudes about early detection. In this population sample, SES differences in fatalism partly explained SES differences in the perceived value of early detection and fear of symptom presentation. Fatalistic beliefs about cancer should be targeted to promote early presentation of cancer and this may be particularly important for lower SES groups. ©2011 AACR

The risk of case-fatality following hospitalisation for asthma has not been well characterised. We describe trends in 30 day case-fatality following hospitalisation for asthma in adults in Scotland from 1981 to 2009. Using the Scottish Morbidity Record Scheme (SMR01) with all asthma hospitalisations for adults (≥18 years) with ICD9 493 and ICD10 J45-J46 in the principal diagnostic position at discharge (1981-2009). These data were linked to mortality data from the General Register Office for Scotland (GROS), with asthma case-fatality defined as death within 30 days of asthma admission (in or out of hospital). Logistic regression was used to explore the impact of age, sex, previous asthma admission (in the 12 months prior to hospitalisation), socioeconomic deprivation, year of admission and co-morbidity on 30-day case-fatality. There were a total of 116,457 asthma hospitalisations; a total of 1000 (0.9%) hospitalisations resulted in a post-admission death (within 30 days of admission). Odds ratios for unadjusted and adjusted case-fatality showed a decreased risk of case-fatality from the mid-1990s onwards when compared to case-fatality in 1981. Advancing age and co-morbid diagnoses of respiratory failure, cancer, renal failure, cor pulmonale, coronary heart disease and respiratory infection were associated with increased likelihood of death. 30 day case-fatality has declined over the last three decades, comparable to case-fatality reported in other parts of the U.K. This decline may be in part due to improved guidelines, protocols and disease management for asthma over the last 30 years. The likelihood of death 30 days following an asthma admission increased with age group and was associated with respiratory failure, renal failure and cancer. Copyright © 2013 Elsevier Ltd.

Nordic ski-jumping fatalities are rare events. Six jumping fatalities have occurred in the United States during the past 50 years. The fatality rate for nordic ski jumping, estimated to be roughly 12 fatalities/100,000 participants annually, appears to be within the range of fatality rates for other "risky" outdoor sports. Cervical fractures appear to be the most frequent fatal ski-jumping injury.

Personal beliefs about health and illness influence many people's decisions about seeking care. This research represents a study of beliefs about breast cancer held by African women in Ghana. In-person interviews based on the revised Powe fatalism inventory (rPFI) were held with 109 women. Correlational analysis and factor analysis were performed. There were negative, nonsignificant associations between fatalism and age (r = -.095, p = 0.33), and educational level (r = -.078, p = .422). Fatalism scores were relatively low, 3.78 on an 11 -point scale. Comparisons are made to responses by African American women in other studies.

Cancer fatalism, which can be understood as the belief that cancer is a death sentence, has been found to be a deterrent to preventive cancer screening participation. This study examines factors associated with breast cancer fatalism among women. We analyzed data from a 2003 survey of women 40 years of age. The survey collected information about respondents' knowledge and attitudes regarding breast health. Analyses compared the characteristics of women who reported and those who did not report a fatalistic attitude. Women with a fatalistic attitude were more likely to be African American, to have a family history of breast cancer, to rate their quality of care as fair or poor, to believe that not much could be done to prevent breast cancer, to believe that breast cancer could not be cured if found early, and to believe that treatment could be worse than the disease.

Inhalation abuse of volatile solvents, previously known generically as "glue sniffing," is typically pursued by adolescents. A wide range of legal, easily obtained products containing volatile substances are available for abuse. We report two illustrative cases of fatal volatile substance abuse: gasoline sniffing in a 20-year-old man and aerosol propellant gas inhalation (aerosol air freshener) in a 16-year-old girl with underlying reactive airway disease. Although the ratio of deaths to nonfatal inhalation escapades is extremely low, volatile solvent abuse carries the risk of sudden death due to cardiac arrest after a dysrhythmia or vasovagal event, central nervous system respiratory depression, hypoxia and hypercapnia due to the techniques of inhalation, and other mechanisms. Investigation of the patient's substance abuse history, examination of the scene of death, and special toxicologic analyses are critical to identifying volatile substance inhalation abuse as the cause of death because anatomic autopsy findings will typically be nonspecific. Above all, physicians must suspect the diagnosis of volatile substance inhalation abuse, especially in any case of sudden death involving an otherwise healthy young person.

Yellow fever virus is a mosquito-borne flavivirus that causes yellow fever, an acute infectious disease that occurs in South America and sub-Saharan Africa. Most patients with yellow fever are asymptomatic, but among the 15% who develop severe illness, the case fatality rate is 20%-60%. Effective live-attenuated virus vaccines are available that protect against yellow fever (1). An outbreak of yellow fever began in Brazil in December 2016; since July 2017, cases in both humans and nonhuman primates have been reported from the states of São Paulo, Minas Gerais, and Rio de Janeiro, including cases occurring near large urban centers in these states (2). On January 16, 2018, the World Health Organization updated yellow fever vaccination recommendations for Brazil to include all persons traveling to or living in Espírito Santo, São Paulo, and Rio de Janeiro states, and certain cities in Bahia state, in addition to areas where vaccination had been recommended before the recent outbreak (3). Since January 2018, 10 travel-related cases of yellow fever, including four deaths, have been reported in international travelers returning from Brazil. None of the 10 travelers had received yellow fever vaccination.

Measles virus (MV) infection causes an acute childhood disease that can include infection of the central nervous system and can rarely progress to severe neurological disease for which there is no specific treatment. We generated potent antiviral peptide inhibitors of MV entry and spreading and MV-induced cell fusion. Dimers of MV-specific peptides derived from the C-terminal heptad repeat region of the MV fusion protein, conjugated to cholesterol, efficiently protect SLAM transgenic mice from fatal MV infection. Fusion inhibitors hold promise for the prophylaxis of MV infection in unvaccinated and immunocompromised people, as well as potential for the treatment of grave neurological complications of measles.
Full Text Available Staphylococcal toxic shock syndrome (STSS is an acute, toxin-mediated febrile illness that rapidly leads to multiple organ dysfunction syndromes, and systemic lupus erythematosus (SLE is a multisystem autoimmune and inflammatory disease. Differential diagnosis in STSS involved a number of common diseases associated with a wide range of nonmenstrual-related conditions, including SLE. Therefore, it is difficult to distinguish from each other initially. We report a case of concurrent fatal STSS and SLE who was treated as sepsis initially, which leads to grave prognosis.

Full Text Available Abstract Introduction Reversible posterior leukoencephalopathy syndrome – a reversible subacute global encephalopathy clinically presenting with headache, altered mental status, visual symptoms such as hemianopsia or cortical blindness, motor symptoms, and focal or generalized seizures – is characterized by a subcortical vasogenic edema symmetrically affecting posterior brain regions. Complete reversibility of both clinical signs and magnetic resonance imaging lesions is regarded as a defining feature of reversible posterior leukoencephalopathy syndrome. Reversible posterior leukoencephalopathy syndrome is almost exclusively seen in the setting of a predisposing clinical condition, such as pre-eclampsia, systemic infections, sepsis and shock, certain autoimmune diseases, various malignancies and cytotoxic chemotherapy, transplantation and concomitant immunosuppression (especially with calcineurin inhibitors as well as episodes of abrupt hypertension. We describe for the first time clinical, radiological and histological findings in a case of reversible posterior leukoencephalopathy syndrome with an irreversible and fatal outcome occurring in the absence of any of the known predisposing clinical conditions except for a hypertensive episode. Case presentation A 58-year-old Caucasian woman presented with a two-week history of subacute and progressive occipital headache, blurred vision and imbalance of gait and with no evidence for raised arterial blood pressure during the two weeks previous to admission. Her past medical history was unremarkable except for controlled arterial hypertension. Cerebral magnetic resonance imaging demonstrated cortical and subcortical lesions with combined vasogenic and cytotoxic edema atypical for both venous congestion and arterial infarction. Routine laboratory and cerebrospinal fluid parameters were normal. The diagnosis of reversible posterior leukoencephalopathy syndrome was established. Within hours after

The current national opioid epidemic is a public health emergency. We have identified an outbreak of exaggerated opioid toxicity caused by fentanyl adulterated tablets purchased on the street as hydrocodone/acetaminophen. Over an 8-day period in late March 2016, a total of 18 patients presented to our institution with exaggerated opioid toxicity. The patients provided a similar history: ingesting their "normal dose" of hydrocodone/acetaminophen tablets but with more pronounced symptoms. Toxicology testing and analysis was performed on serum, urine, and surrendered pills. One of the 18 patients died in hospital. Five patients underwent cardiopulmonary resuscitation, one required extracorporeal life support, three required intubation, and two received bag-valve-mask ventilation. One patient had recurrence of toxicity after 8 hours after naloxone discontinuation. Seventeen of 18 patients required boluses of naloxone, and four required prolonged naloxone infusions (26-39 hours). All 18 patients tested positive for fentanyl in the serum. Quantitative assays conducted in 13 of the sera revealed fentanyl concentrations of 7.9 to 162 ng/mL (mean = 52.9 ng/mL). Pill analysis revealed fentanyl amounts of 600-6,900 μg/pill. The pills are virtually indistinguishable from authentic hydrocodone/acetaminophen tablets and are similar in weight. To date, our county has reported 56 cases of fentanyl opioid toxicity, with 15 fatalities. In our institution, the outbreak has stressed the capabilities and resources of the emergency department and intensive care units. A serious outbreak of exaggerated opioid toxicity caused by fentanyl-adulterated tablets purchased on the street as hydrocodone/acetaminophen is under way in California. These patients required higher dosing and prolonged infusions of naloxone. Additionally, observation periods off naloxone were extended due to delayed, recurrent toxicity. The outbreak has serious ramifications for public health and safety, law

To examine the pattern of injuries in cases of fatal shark attack in South Australian waters, the authors examined the files of their institution for all cases of shark attack in which full autopsies had been performed over the past 25 years, from 1974 to 1998. Of the seven deaths attributed to shark attack during this period, full autopsies were performed in only two cases. In the remaining five cases, bodies either had not been found or were incomplete. Case 1 was a 27-year-old male surfer who had been attacked by a shark. At autopsy, the main areas of injury involved the right thigh, which displayed characteristic teeth marks, extensive soft tissue damage, and incision of the femoral artery. There were also incised wounds of the right wrist. Bony injury was minimal, and no shark teeth were recovered. Case 2 was a 26-year-old male diver who had been attacked by a shark. At autopsy, the main areas of injury involved the left thigh and lower leg, which displayed characteristic teeth marks, extensive soft tissue damage, and incised wounds of the femoral artery and vein. There was also soft tissue trauma to the left wrist, with transection of the radial artery and vein. Bony injury was minimal, and no shark teeth were recovered. In both cases, death resulted from exsanguination following a similar pattern of soft tissue and vascular damage to a leg and arm. This type of injury is in keeping with predator attack from underneath or behind, with the most severe injuries involving one leg. Less severe injuries to the arms may have occurred during the ensuing struggle. Reconstruction of the damaged limb in case 2 by sewing together skin, soft tissue, and muscle bundles not only revealed that no soft tissue was missing but also gave a clearer picture of the pattern of teeth marks, direction of the attack, and species of predator.

This paper provides a database representing injury mortality in Dammam, Saudi Arabia, with the aim of establishing a system which will record information about the incidence of such deaths, identify new trends and give priority to violence prevention. The retrospective study was carried out on 64 fatalities from gunfire injuries at the Forensic Medicine Centre in Dammam, Saudi Arabia during the period from January 2002 - December 2006. The deaths included 55 cases of homicide, seven cases of suicide and two accidental shootings. Twenty-six victims were aged between 16-30 years and 24 victims were between 31-45 years. Fifty-nine of the cases were male. A handgun was the weapon used in 49 cases. The most common sites for the firearm entrance wounds were the head (45 cases) and the chest (35 cases). In the majority of cases (56.3%) a single shot was fired while in 15.6% of cases there were two shots. In 51.5% of cases no bullet was recovered from the body while a single bullet was recovered in 31.5% and two bullets in 6.2% of the cases. Distant range fire was observed in 65.6% of cases. Exit wounds were found on the head in 36.7% and on the chest in 28.7% of cases. The majority of victims were young males living in urban areas. This result should help in forming a strategy to improve the livelihoods of this group. The low incidence of alcohol abuse (one case, 1.56%) and only three cases (4.68%) of amphetamine abuse is significant.

Emergency department visits and hospital admissions resulting from adult bicycle trauma have increased dramatically. Annual medical costs and work losses of these incidents last were estimated for 2005 and quality-of-life losses for 2000. We estimated costs associated with adult bicycle injuries in the USA using 1997-2013 non-fatal incidence data from the National Electronic Injury Surveillance System with cost estimates from the Consumer Product Safety Commission's Injury Cost Model, and 1999-2013 fatal incidence data from the National Vital Statistics System costed by similar methods. Approximately 3.8 million non-fatal adult bicycle injuries were reported during the study period and 9839 deaths. In 2010 dollars, estimated adult bicycle injury costs totalled $24.4 billion in 2013. Estimated injury costs per mile bicycled fell from $2.85 in 2001 to $2.35 in 2009. From 1999 to 2013, total estimated costs were $209 billion due to non-fatal bicycle injuries and $28 billion due to fatal injuries. Inflation-free annual costs in the study period increased by 137% for non-fatal injuries and 23% for fatal injuries. The share of non-fatal costs associated with injuries to riders age 45 and older increased by 1.6% (95% CI 1.4% to 1.9%) annually. The proportion of costs due to incidents that occurred on a street or highway steadily increased by 0.8% (95% CI 0.4% to 1.3%) annually. Inflation-free costs per case associated with non-fatal bicycle injuries are increasing. The growth in costs is especially associated with rising ridership, riders 45 and older, and street/highway crashes. Published by the BMJ Publishing Group Limited.

90% of the global burden of injuries is borne by low-income and middle-income countries (LMICs). However, details of the injury burden in LMICs are less clear because of the scarcity of data and population-based studies. The Saving of Lives from Drowning project, implemented in rural Bangladesh, did a census on 1·2 million people to fill this gap. This Article describes the epidemiology of fatal and non-fatal injuries from the study. In this study, we used data from the baseline census conducted as part of the Saving of Lives from Drowning (SoLiD) project. The census was implemented in 51 unions from seven purposively sampled rural subdistricts of Bangladesh between June and November, 2013. Sociodemographic, injury mortality, and morbidity information were collected for the whole population in the study area. We analysed the data for descriptive measures of fatal and non-fatal injury outcomes. Age and gender distribution, socioeconomic characteristics, and injury characteristics such as external cause, intent, location, and body part affected were reported for all injury outcomes. The census covered a population of 1 169 593 from 270 387 households and 451 villages. The overall injury mortality rate was 38 deaths per 100 000 population per year, and 104 703 people sustained major non-fatal injuries over a 6-month recall period. Drowning was the leading external cause of injury death for all ages, and falls caused the most number of non-fatal injuries. Fatal injury rates were highest in children aged 1-4 years. Non-fatal injury rates were also highest in children aged 1-4 years and those aged 65 years and older. Males had more fatal and non-fatal injuries than females across all external causes except for burns. Suicide was the leading cause of injury deaths in individuals aged 15-24 years, and more than 50% of the suicides occurred in females. The home environment was the most common location for most injuries. The burden of fatal and non-fatal injuries

. For all countries the distribution of deaths according to geographical regions showed a decreasing number of drug deaths in the metropolitan area and an increasing number in other cities. Heroin/ morphine dominated as the cause of death and was responsible for about 90% of the cases in Norway. In Sweden...... and Denmark, however, heroin/morphine caused only about 70% of the fatal poisonings. About 30% of the fatal poisonings in Denmark and Sweden were caused by other group I drugs, in Denmark mainly methadone and in Sweden mainly propoxyphene.

In this paper we describe revisions to the NASA Space Cancer Risk (NSCR) model focusing on updates to probability distribution functions (PDF) representing the uncertainties in the radiation quality factor (QF) model parameters and the dose and dose-rate reduction effectiveness factor (DDREF). We integrate recent heavy ion data on liver, colorectal, intestinal, lung, and Harderian gland tumors with other data from fission neutron experiments into the model analysis. In an earlier work we introduced distinct QFs for leukemia and solid cancer risk predictions, and here we consider liver cancer risks separately because of the higher RBE's reported in mouse experiments compared to other tumors types, and distinct risk factors for liver cancer for astronauts compared to the U.S. The revised model is used to make predictions of fatal cancer and circulatory disease risks for 1-year deep space and International Space Station (ISS) missions, and a 940 day Mars mission. We analyzed the contribution of the various model parameter uncertainties to the overall uncertainty, which shows that the uncertainties in relative biological effectiveness (RBE) factors at high LET due to statistical uncertainties and differences across tissue types and mouse strains are the dominant uncertainty. NASA's exposure limits are approached or exceeded for each mission scenario considered. Two main conclusions are made: 1) Reducing the current estimate of about a 3-fold uncertainty to a 2-fold or lower uncertainty will require much more expansive animal carcinogenesis studies in order to reduce statistical uncertainties and understand tissue, sex and genetic variations. 2) Alternative model assumptions such as non-targeted effects, increased tumor lethality and decreased latency at high LET, and non-cancer mortality risks from circulatory diseases could significantly increase risk estimates to several times higher than the NASA limits.

The finding that the relative safety disadvantage of small compared with large cars is less for post-1980 cars than for pre-1980 cars has stimulated speculation that increasing fuel economy standards would increase fatalities less than previously expected. Fatal crashes between two cars of similar model year were examined to see whether this would be the case. Driver fatality risk in relation to car mass was examined with Fatal Accident Reporting System data for crashes between two cars of a specific model year. The relative risk for driver fatality in the lighter car compared with the other driver's risk in a car 50% heavier was as follows: for 1966 through 1979 cars, the risk was between 3.7 and 5.1; for 1984 cars, 2.6; and for 1990 cars, 4.1. The results suggest that the lesser mass effect observed for mid-1980s cars occurred because improved crashworthiness features appeared in small cars earlier than in large cars. As all cars are redesigned, the relationship between risk and mass can be expected to approach that observed earlier in pre-1980 cars. If so, future fatality increases from fuel economy increases will be greater than estimated on the basis of mid-1980 data.

Social inequalities in coronary heart disease mortality have roots in childhood conditions, but it is unknown whether they are associated both with the incidence of the disease and the following survival. We studied how several different early-life socioeconomic factors, together with later socioeconomic attainment, were associated with myocardial infarction (MI) incidence and fatality in Finland. The data was based on a register-based sample of households from a census in 1950 that also provided information on childhood circumstances. MI hospitalizations and mortality in 1988-2010 were studied in those who were up to 14 years of age at the time of the census and resident in Finland in 1987 (n = 94,501). Parental education, occupation, household crowding, home ownership, and family type were examined together with adulthood education and income. Hazard and odds ratios with 95% confidence intervals (CI) were calculated using Cox regression (incidence and long-term fatality) and logistic regression (short-term fatality) models. Lower parental education, occupational background and greater household crowding were associated with MI incidence. In models adjusted for adulthood variables, crowding increased the risk by 16% (95% CI 5-29%) in men and 25% (95% CI 3-50%) in women. Short-term survival was more favourable in sons of white-collar parents and daughters of owner-occupied households, but most aspects of childhood circumstances did not strongly influence long-term fatality risk. Socioeconomic attainment in adulthood accounted for a substantial part of the effects of childhood conditions, but the measured childhood factors explained little of the disparities by adulthood education and income. Moreover, income and education remained associated with MI incidence when adjusted for unobserved shared family factors in siblings. Though social and economic development in society seems to have mitigated the disease burden associated with poor childhood living conditions

Over 30,000 people die annually in the United States from injuries caused by firearms. Although most firearm laws are enacted by states, whether the laws are associated with rates of firearm deaths is uncertain. To evaluate whether more firearm laws in a state are associated with fewer firearm fatalities. Using an ecological and cross-sectional method, we retrospectively analyzed all firearm-related deaths reported to the Centers for Disease Control and Prevention Web-based Injury Statistics Query and Reporting System from 2007 through 2010. We used state-level firearm legislation across 5 categories of laws to create a "legislative strength score," and measured the association of the score with state mortality rates using a clustered Poisson regression. States were divided into quartiles based on their score. Fifty US states. Populations of all US states. The outcome measures were state-level firearm-related fatalities per 100,000 individuals per year overall, for suicide, and for homicide. In various models, we controlled for age, sex, race/ethnicity, poverty, unemployment, college education, population density, nonfirearm violence-related deaths, and household firearm ownership. Over the 4-year study period, there were 121,084 firearm fatalities. The average state-based firearm fatality rates varied from a high of 17.9 (Louisiana) to a low of 2.9 (Hawaii) per 100,000 individuals per year. Annual firearm legislative strength scores ranged from 0 (Utah) to 24 (Massachusetts) of 28 possible points. States in the highest quartile of legislative strength (scores of ≥9) had a lower overall firearm fatality rate than those in the lowest quartile (scores of ≤2) (absolute rate difference, 6.64 deaths/100,000/y; age-adjusted incident rate ratio [IRR], 0.58; 95% CI, 0.37-0.92). Compared with the quartile of states with the fewest laws, the quartile with the most laws had a lower firearm suicide rate (absolute rate difference, 6.25 deaths/100,000/y; IRR, 0.63; 95% CI, 0

Full Text Available Cerebral malaria (CM is a severe complication of Plasmodium falciparum infection that results in thousands of deaths each year, mostly in African children. The in vivo mechanisms underlying this fatal condition are not entirely understood. Using the animal model of experimental cerebral malaria (ECM, we sought mechanistic insights into the pathogenesis of CM. Fatal disease was associated with alterations in tight junction proteins, vascular breakdown in the meninges / parenchyma, edema, and ultimately neuronal cell death in the brainstem, which is consistent with cerebral herniation as a cause of death. At the peak of ECM, we revealed using intravital two-photon microscopy that myelomonocytic cells and parasite-specific CD8+ T cells associated primarily with the luminal surface of CNS blood vessels. Myelomonocytic cells participated in the removal of parasitized red blood cells (pRBCs from cerebral blood vessels, but were not required for the disease. Interestingly, the majority of disease-inducing parasite-specific CD8+ T cells interacted with the lumen of brain vascular endothelial cells (ECs, where they were observed surveying, dividing, and arresting in a cognate peptide-MHC I dependent manner. These activities were critically dependent on IFN-γ, which was responsible for activating cerebrovascular ECs to upregulate adhesion and antigen-presenting molecules. Importantly, parasite-specific CD8+ T cell interactions with cerebral vessels were impaired in chimeric mice rendered unable to present EC antigens on MHC I, and these mice were in turn resistant to fatal brainstem pathology. Moreover, anti-adhesion molecule (LFA-1 / VLA-4 therapy prevented fatal disease by rapidly displacing luminal CD8+ T cells from cerebrovascular ECs without affecting extravascular T cells. These in vivo data demonstrate that parasite-specific CD8+ T cell-induced fatal vascular breakdown and subsequent neuronal death during ECM is associated with luminal, antigen

Precise estimation of the relative risk of motorcyclists being involved in a fatal accident compared to car drivers is difficult. Simple estimates based on the proportions of licenced drivers or riders that are killed in a fatal accident are biased as they do not take into account the exposure to risk. However, exposure is difficult to quantify. Here we adapt the ideas behind the well known induced exposure methods and use available summary data on speeding detections and fatalities for motorcycle riders and car drivers to estimate the relative risk of a fatality for motorcyclists compared to car drivers under mild assumptions. The method is applied to data on motorcycle riders and car drivers in Victoria, Australia in 2010 and a small simulation study is conducted. Copyright © 2013 Elsevier Ltd. All rights reserved.
Evolução fatal da co-infecção doença de Chagas/Aids: dificuldades diagnósticas entre a reagudização da miocardite e a miocardiopatia chagásica crônica Fatal evolution of Chagas'disease/Aids co-infection: diagnostic difficulties between myocarditis reactivation and chronic chagasic myocardiopathy

Full Text Available A doença de Chagas é uma parasitose causada pelo protozoário Trypanosoma cruzi, transmitido por insetos triatomíneos. A doença ocorre desde o sul dos Estados Unidos da América do Norte até a Argentina, sendo que, aproximadamente, 14 milhões de pessoas devam estar infectados na América Latina, predominantemente na forma crônica da doença. A reagudização da doença de Chagas pode ocorrer em imunossuprimidos, como tem sido observado em pacientes com aids. Verificou-se descompensação cardíaca em um destes casos, com grave disfunção ventricular e arritmias sendo considerada a possibilidade de reagudização da doença de Chagas no miocárdio, uma vez que o xenodiagnóstico foi positivo. Face a gravidade foi tratado especificamente para o Trypanosoma cruzi com benznidazol, porém sem completar o tempo estipulado para este fim, vindo a falecer em conseqüência de complicações da cardiopatia. A necropsia apresentou os estigmas habituais da cardiopatia chagásica crônica como miocardite fibrosante e redução do número de neurônios no tubo digestório, não sendo encontradas formas amastigotas do Trypanosoma cruzi em nenhum dos tecidos examinados. Assim, não ficou demonstrada a reagudização da doença de Chagas, mas sim evolução natural da cardiopatia chagásica crônica.Chagas disease is a type of parasitosis caused by the protozoan Trypanosoma cruzi, and it is transmitted by triatomine insects. This disease is found between the southern United States to Argentina and approximately 14 million people in Latin America are believed to be infected, predominantly with the chronic form of the disease. Reactivation of Chagas disease can occur among immunosuppressed patients, as has been observed among AIDS patients. In one such case, we observed cardiac decompensation with severe ventricular dysfunction and arrhythmias. This case was thought to be reactivation of Chagas disease in the myocardium, since the xenodiagnosis was
Full Text Available The aim of this study was to identify risk factors associated with confirmed fatal hyperglycaemia, which could predispose potentially preventable deaths in individuals on glucose lowering drugs.A retrospective register-based case-control study conducted on a nationwide cohort with individuals who died due to hyperglycaemia as determined by forensic postmortem examination, in Sweden August 2006 to December 2012. Vitreous glucose was used to diagnose hyperglycaemia postmortem. The forensic findings stored in the National Forensic Medicine Database were linked to nationwide registers. Cases that died due to confirmed hyperglycemia with dispensed glucose lowering drugs were identified and living controls with dispensed glucose lowering drugs were randomly selected in the Swedish prescribed drug register and matched on age and sex. Information on comorbidities, dispensed pharmaceuticals, clinical data and socioeconomic factors were obtained for cases and controls. Adjusted multiple logistic regression models were used to identify risk factors associated with fatal hyperglycaemia.During the study period 322 individuals, mostly males (79% with the mean age of 53.9 years (SD.± 14 died due to confirmed hyperglycaemia. Risk factors for fatal hyperglycaemia included; insulin treatment (OR = 4.40; 95%CI,1.96, 9.85, poor glycaemic control (OR = 2.00 95%CI,1.23, 3.27, inadequate refill-adherence before death (OR = 3.87; 95%CI,1.99, 7.53, microvascular disease (OR = 3.26; 95% CI, 1.84, 5.79, psychiatric illness (OR = 2.30; 95% CI,1.32, 4.01, substance abuse (OR = 8.85; 95%CI,2.34, 35.0 and/or living alone (OR = 2.25; 95%CI,1.21, 4.18.Our results demonstrate the importance of clinical attention to poor glycaemic control in subjects with psychosocial problems since it may indicate serious non-adherence, which consequently could lead to fatal hyperglycaemia.

Extremity hemorrhage is a contributor to preventable battlefield mortality. The Army has liberalized tourniquet use guidelines in an attempt to prevent these deaths. To evaluate wound hemostatic agents that might allow for early tourniquet removal while maintaining hemorrhage control, a model of lethal extremity hemorrhage in the goat (Capra hircus) was developed and a polymeric dressing agent (BioFoam) tested. After administration of a spinal block, animals were placed in lateral recumbancy with a head-up tilt of 6 degrees, 500 mL crystalloid was injected and 600 u/Kg of heparin was administered. After tourniquet application to the thigh, a soft tissue and vascular injury was created by transecting muscles and the femoral artery. The polymeric wound dressing was applied and the tourniquet was released. In testing, the primary endpoint was mortality within the first hour after tourniquet release. None of the control animals survived the full hour. Two out of five (40%) of the treated animals survived. With survivors' survival time calculated as 60 minutes, survival time was found not to differ between treated (34 +/- 19 minutes) and untreated (29 +/- 18 minutes) animals (p = 0.77). The physical characteristics of tissue injury, need for anticoagulation, and manipulation of blood pressure are vital factors contributing to the lethality of a large animal fatal extremity hemorrhage model. BioFoam was successful in preventing fatal arterial extremity hemorrhage after the release of an effective tourniquet in some cases. An agent that can reliably allow for safe tourniquet removal and restoration of collateral circulation is a potential solution to tourniquet-associated morbidity in traumatic extremity injury. The model developed will serve as a rigorous test for such agents.

Full Text Available Abstract 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.

The incidence and severity of civilian public mass shootings (CPMS) continue to rise. Initiatives predicated on lessons learned from military woundings have placed strong emphasis on hemorrhage control, especially via use of tourniquets, as means to improve survival. We hypothesize that both the overall wounding pattern and the specific fatal wounds in CPMS events are different from those in military combat fatalities and thus may require a new management strategy. A retrospective study of autopsy reports for all victims involved in 12 CPMS events was performed. Civilian public mass shootings was defined using the FBI and the Congressional Research Service definition. The site of injury, probable site of fatal injury, and presence of potentially survivable injury (defined as survival if prehospital care is provided within 10 minutes and trauma center care within 60 minutes of injury) was determined independently by each author. A total 139 fatalities consisting of 371 wounds from 12 CPMS events were reviewed. All wounds were due to gunshots. Victims had an average of 2.7 gunshots. Relative to military reports, the case fatality rate was significantly higher, and incidence of potentially survivable injuries was significantly lower. Overall, 58% of victims had gunshots to the head and chest, and only 20% had extremity wounds. The probable site of fatal wounding was the head or chest in 77% of cases. Only 7% of victims had potentially survivable wounds. The most common site of potentially survivable injury was the chest (89%). No head injury was potentially survivable. There were no deaths due to exsanguination from an extremity. The overall and fatal wounding patterns following CPMS are different from those resulting from combat operations. Given that no deaths were due to extremity hemorrhage, a treatment strategy that goes beyond use of tourniquets is needed to rescue the few victims with potentially survivable injuries.

Full Text Available The apparent high number of deaths in Argentina during the 2009 pandemic led to concern that the influenza A H1N1pdm disease was different there. We report the characteristics and risk factors for influenza A H1N1pdm fatalities.We identified laboratory-confirmed influenza A H1N1pdm fatalities occurring during June-July 2009. Physicians abstracted data on age, sex, time of onset of illness, medical history, clinical presentation at admission, laboratory, treatment, and outcomes using standardize questionnaires. We explored the characteristics of fatalities according to their age and risk group.Of 332 influenza A H1N1pdm fatalities, 226 (68% were among persons aged <50 years. Acute respiratory failure was the leading cause of death. Of all cases, 249 (75% had at least one comorbidity as defined by Advisory Committee on Immunization Practices. Obesity was reported in 32% with data and chronic pulmonary disease in 28%. Among the 40 deaths in children aged <5 years, chronic pulmonary disease (42% and neonatal pathologies (35% were the most common co-morbidities. Twenty (6% fatalities were among pregnant or postpartum women of which only 47% had diagnosed co-morbidities. Only 13% of patients received antiviral treatment within 48 hours of symptom onset. None of children aged <5 years or the pregnant women received antivirals within 48 h of symptom onset. As the pandemic progressed, the time from symptom-onset to medical care and to antiviral treatment decreased significantly among case-patients who subsequently died (p<0.001.Persons with co-morbidities, pregnant and who received antivirals late were over-represented among influenza A H1N1pdm deaths in Argentina, though timeliness of antiviral treatment improved during the pandemic.

Nosocomial pneumonia (NP) and ventilator associated pneumonia (VAP) have been associated with financially significant economic burden and increased case fatality rate in adult intensive care units (ICUs). This study was designed to evaluate case fatality rate among patients with NP and VAP in a respiratory ICU. In 2008-2013, VAP and NP in the ICUs were included in this retrospective single-centre cohort study. Data on demographics, co-morbidities, severity of illness, mechanical ventilation, empirical treatment, length of hospital stay and laboratory findings were recorded in each group, as were case fatality rate during ICU admission and after discharge including short-term (28-day) and long-term (a year) case fatality rate. A total of 108 patients with VAP (n = 64, median (IQR) age: 70 (61-75) years, 67.2% were men) or NP (n = 44, median (IQR) age: 68 (62-74) years, 68.2% were men) were found. Appropriate empirical antibiotic therapy was identified only in 45.2 and 42.9% of patients with VAP and NP, respectively. Overall case fatality rate in VAP and NP (81.3 vs 84.1), ICU case fatality rate (42.2 vs 45.5%), short-term case fatality rate (15.6 vs 27.3%) and long-term case fatality rate (23.4 vs 11.4%) were similar between VAP and NP groups along with occurrence 50% of case fatality rate cases in the first 2 months and 90% within the first year of discharge. Multivariate analysis showed that chronic obstructive pulmonary disease (COPD) (HR: 3.15, 95% CI: 1.06-9.38; p = 0.039) and presence of septic shock (HR: 3.83, 95% CI: 1.26-11.60; p = 0.018) were independently associated with lower survival. In conclusion, our findings in a retrospective cohort of respiratory ICU patients with VAP or NP revealed high ICU, short- and long-term case fatality rates within 1 year of diagnosis, regardless of the diagnosis of NP after 48 h of initial admission or after induction of ventilator support. COPD and presence of septic shock are associated with high

Fatalism is a grounded cultural belief that is common among Arabs and is known to hinder self-care in chronic diseases including diabetes (Nabolsi and Carson in Scand J Caring Sci 25(4):716-724, 2011). The purpose of this study is to identify predictors of diabetes fatalism in this population. Data on 280 Lebanese patients with type 2 diabetes (mean age 58.24 ± 13.48 years; mean HbA1c 7.90 ± 1.90%; 53.76% females) recruited from one hospital in greater Beirut, Lebanon, and from the community using snowballing technique were examined. Multiple linear regression was used to assess the independent association between diabetes fatalism and demographic and patient characteristics. Age (β = -.14, 95% CI -.27, -.002), BMI (β = .35, 95% CI .15; .54), level of education (β = -3.98, 95% CI -7.64; -.32) and number of diabetes problems (β = -5.03, 95% CI -9.89; -.18) were significantly associated with diabetes fatalism in the regression model. The combination of demographic and patient characteristics accounted for 14.5% of the variance in diabetes fatalism scores' change. Patients with type 2 diabetes who exhibited more fatalistic attitudes were younger, of lower education levels, had higher BMI and had fewer diabetes comorbidities. Such findings are crucial for healthcare practitioners to identify fatalistic patients and to tailor culturally appropriate strategies in diabetes management. Further studies are warranted to explore other potential determinants of diabetes fatalism with larger sample and non-Lebanese Arabic population.

Full Text Available BACKGROUND: Dengue is a mosquito-borne viral disease endemic in many countries in the tropics and sub-tropics. The disease affects mainly children, but in recent years it is becoming more of an adult disease. Malaysia experienced a large dengue outbreak in 2006 to 2007, involving mostly adults, with a high number of deaths. METHODOLOGY/PRINCIPAL FINDINGS: We undertook a retrospective study to examine dengue death cases in our hospital from June 2006 to October 2007 with a view to determine if there have been changes in the presentation of severe to fatal dengue. Nine of ten fatal cases involved adult females with a median age of 32 years. All had secondary dengue infection. The mean duration of illness prior to hospitalization was 4.7 days and deaths occurred at an average of 2.4 days post-admission. Gastrointestinal pain, vomiting, diarrhea, intravascular leakages and bleeding occurred in the majority of cases. DSS complicated with severe bleeding, multi-organ failure and coagulopathy were the primary causes of deaths. Seven patients presented with thrombocytopenia and hypoalbuminemia, five of which had hemoconcentration and increased ALT and AST indicative of liver damage. Co-morbidities particularly diabetes mellitus was common in our cohort. Prominent unusual presentations included acute renal failure, acute respiratory distress syndrome, myocarditis with pericarditis, and hemorrhages over the brain and heart. CONCLUSIONS: In our cohort, dengue fatalities are seen primarily in adult females with secondary dengue infection. The majority of the patients presented with common clinical and laboratory warning signs of severe dengue. Underlying co-morbidities may contribute to the rapid clinical deterioration in severe dengue. The uncommon presentations of dengue are likely a reflection of the changing demographics where adults are now more likely to contract dengue in dengue endemic regions.

School-based violence, and fatal school shootings in particular, have gained increased attention in the media and psychological literature. Most reports have focused on the characteristics of perpetrators, but there is a growing awareness that school-related factors may also influence the occurrence of fatal school shootings. The current study examined several key characteristics of all schools where random (38) and targeted (96) fatal shootings occurred in the United States between 1966 and 2009. These were compared with a group (138) of schools randomly selected to represent the population of all schools in the United States. The size of a school's enrollment, urban or suburban locale, public funding, and predominantly non-white enrollment were positively associated with fatal shootings. Universities and colleges were disproportionately associated with random shootings and high schools with targeted ones. It was proposed that characteristics of schools that allow feelings of anonymity or alienation among students may help create environmental conditions associated with fatal school shootings. Implications for future research and interventions are considered.

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, poil and gas establishments (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.

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.

The aim of this study was to evaluate the trend of occupational injuries in Turkey using epidemiologic criteria such as incidence mortality and fatality/all injuries recorded - rates. Safety and health data were obtained from the Annual Statistic Books of the Social Insurance Institution (1988-2006) and Social Security Institution (2007-2011) of Turkey. The results from the official data showed that although total employment is increasing the number of occupational injuries and incidence and mortality rates are decreasing. The results also demonstrate that occupational fatality/all injuries recorded - rate is increasing. The fatality/all injuries recorded - rate per 1000 injuries increased to 25.5 in 2011 from 8.6 in 1988. Each work day an average of five people died because of occupational injuries. The fatality/all injuries recorded - rate (the number of fatal cases per 1000 occupational injuries) is an important indicator of the injury rate for a country. Systems of occupational injury and illness surveillance constitute a critical resource for the management and reduction of occupational injuries and illness.

After a cluster of fatal toxoplasmosis among stem cell transplant recipients at 2 hospitals, surveillance with polymerase chain reaction (PCR) (blood) was instituted. Rate of reactivation among seropositive recipients was 2.2 and 16%. Parasitemia was successfully managed with preemptive treatment. For seropositive recipients unable to take prophylaxis, toxoplasma PCR surveillance should be routinely performed. © The Author 2016.

Mucormycosis is an invasive mycotic disease caused by fungi in the zygomycetes class. Although ubiquitous in the environment, zygomycetes are rarely known to cause invasive disease in immunocompromised hosts with a high mortality even under aggressive antifungal and surgical therapy. Clinically, mucormycosis frequently affects the sinus occasionally showing pulmonary or cerebral involvement. However skeletal manifestation with Rhizopus microsporus (RM) osteomyelitis leading to emergency surgical proximal femoral resection with fatal outcome has not been described yet. We report the case of a 73-year-old male suffering from myelodysplastic syndrome with precedent bone marrow transplantation. Six months after transplantation he consulted our internal medicine department in a septic condition with a four week history of painful swelling of the right hip. Radiography, computed tomography and magnetic resonance imaging revealed multiple bone infarcts in both femurs. In the right femoral head, neck and trochanteric region a recent infarct showed massive secondary osteomyelitis, breaking through the medial cortex. Emergency surgical proximal femoral resection was performed due to extensive bone and soft tissue destruction. Microbiological and basic local alignment search tool (BLAST) analysis revealed RM. Amphotericin B and posaconazole treatment with septic revision surgery was performed. However the disease ran a rapid course and was fatal two months after hospital admission. This alarming result with extensive RM osteomyelitis in the proximal femur of an immunocompromised patient may hopefully warn medical staff to perform early imaging and aggressive surgical supported multimodal treatment in similar cases.

The diagnosis of death caused by hypothermia can often only be made by exclusion. In this article, we discuss the significance of rectal temperature determination at the death scene for establishing the diagnosis of fatal hypothermia. Six cases of fatal hypothermia subjected to medico-legal autopsy at the Institute of Legal Medicine, Hamburg, Germany, were reviewed. Findings at external examination, autopsy findings with special regard to characteristics hypothermia-related changes, histological findings, and toxicology results were analyzed. In all cases investigated, a discrepancy between a low rectal temperature and other parameters for estimation of the time since death such as still displaceable postmortem lividity and electrical excitability of skeletal muscles was present, leading to the prompt suspicion of fatal hypothermia at the medico-legal death scene investigation. An early death scene investigation by a forensic specialist is of striking importance for establishing the correct diagnosis, because this discrepancy can only be observed in the early postmortem interval.

We examined whether sales of new motorcycles was a mechanism to explain the relationship between motorcycle fatalities and gasoline prices. The data came from the Motorcycle Industry Council, Energy Information Administration and Fatality Analysis Reporting System for 1984-2009. Autoregressive integrated moving average (ARIMA) regressions estimated the effect of inflation-adjusted gasoline price on motorcycle sales and logistic regressions estimated odds ratios (ORs) between new and old motorcycle fatalities when gasoline prices increase. New motorcycle sales were positively correlated with gasoline prices (r = 0.78) and new motorcycle fatalities (r = 0.92). ARIMA analysis estimated that a US$1 increase in gasoline prices would result in 295,000 new motorcycle sales and, consequently, 233 new motorcycle fatalities. Compared to crashes on older motorcycle models, those on new motorcycles were more likely to be young riders, occur in the afternoon, in clear weather, with a large engine displacement, and without alcohol involvement. Riders on new motorcycles were more likely to be in fatal crashes relative to older motorcycles (OR 1.14, 95 % confidence interval (CI) 1.02-1.28) when gasoline prices increase. Our findings suggest that, in response to increasing gasoline prices, people tend to purchase new motorcycles, and this is accompanied with significantly increased crash risk. There are several policy mechanisms that can be used to lower the risk of motorcycle crash injuries through the mechanism of gas prices and motorcycle sales such as raising awareness of motorcycling risks, enhancing licensing and testing requirements, limiting motorcycle power-to-weight ratios for inexperienced riders, and developing mandatory training programs for new riders.

While generally reducing morbidity and mortality, electrical weapons have risks associated with their usage, including eye injuries and falls. With sufficient probe spread, an uncontrolled fall to the ground typically occurs along with the possibility of a fatal brain injury. We analyzed possible risk factors including running and elevated surfaces with established head-injury criteria to estimate the risk of brain injury. We searched for cases of arrest-related or in-custody death, with TASER(®) electrical weapon usage where fall-induced injuries might have contributed to the death. We found 24 cases meeting our initial inclusion criteria of a fatal fall involving electronic control. We then excluded 5 cases as intentional jumps, leaving 19 cases of forced falls. Autopsy reports and other records were analyzed to determine which of these deaths were from brain injury caused by the fall. We found 16 probable cases of fatal brain injuries induced by electronic control from electrical weapons. Out of 3 million field uses, this gives a risk of 5.3 ± 2.6 PPM which is higher than the theoretical risk of electrocution. The mean age was 46 ± 14 years which is significantly greater that the age of the typical ARD (36 ± 10). Probe shots to the subject's back may present a higher risk of a fatal fall. The use of electronic control presents a small but real risk of death from fatal traumatic brain injury. Increased age represents an independent risk factor for such fatalities.

Objective: The aim of this study was to explore the relationship of drunk and drugged driving to the occurrence of fatal crashes associated with speeding, failure to obey/yield, inattention, and seat belt nonuse. Method: We examined data for fatally injured drivers involved in single-vehicle crashes killed in states in which more than 79% of the drivers were tested for drugs other than alcohol and had a known result. Results: About 25% of the drivers tested positive for drugs, a figure almost double that estimated by the 2007 National Roadside Survey. Cannabinoids and stimulants each contributed to about 23% of the drug-positive results (6% among all fatally injured single-vehicle drivers). Stimulants more than cannabinoids were found to be associated with the four types of crashes under study. Some drugs showed a protective effect over the four crash types under study. Significant interactions between drugs and alcohol were observed. Stimulants contributed to the different types of fatal crashes irrespective of the levels of alcohol consumed by the drivers. Conclusions: This study provides further evidence of a link between drug consumption and fatal crashes. It also opens the door to some interesting and sometimes unexpected questions regarding the way drugs contribute to crashes, which we found varies depending on the type of crash considered, the class of drug, and the presence of alcohol. Research is also needed on drugs that could have a protective effect on the occurrence of fatal crashes. These findings could be highly relevant to the design of drug-related traffic laws and programs targeted at curbing drugged driving. PMID:21683038
As part of this research effort, we developed a new methodology for projecting elderly traffic crash fatalities. This methodology separates exposure to crashes from crash risk per se, and further divides exposure into two components, the number of miles driven and the likelihood of being a driver. This component structure permits conceptually different determinants of traffic fatalities to be projected separately and has thorough motivation in behavioral theory. It also permits finer targeting of particular aspects of projections that need improvement and closer linking of projections to possible policy instruments for influencing them.

To explore fatalistic attributions of colon cancer development among Asian and Hispanic Americans in comparison with non-Hispanic whites; also to examine the impacts of fatalism on adherence to the colon cancer screening guideline. For the analysis, the 2005 Health Information National Trends Survey data were employed. Both Asian and Hispanic Americans were more likely to make fatalistic attribution and were less likely to follow the guideline than whites. Particularly for Asians, fatalism was a significant predictor for not adhering to the guideline. These findings emphasize the need for cultural interventions to disrupt fatalistic attitudes towards colon cancer preventions.

To evaluate the effectiveness of a video intervention in decreasing cancer fatalism, increasing knowledge of colorectal cancer, and increasing participation in fecal-occult blood testing (FOBT). Repeated measures, pretest/post-test. Senior citizen centers in a rural southern state. Individuals were selected and assigned to the study group based on the center they attended. Centers were selected and assigned randomly to an intervention (n = 42) or control (n = 28) group. The age of the participants ranged from 52-92 years (X = 75). Pretest measures included the Powe Fatalism inventory, the Colorectal Cancer Knowledge Questionnaire, and the Demographic Data Questionnaire. The intervention group viewed the Medical University of South Carolina's video Telling the Story ... To Live is God's Will, and the control group viewed the American Cancer Society (ACS) video Colorectal Cancer: The Cancer No One Talks About. Hemoccult II kits were distributed to both groups at no cost. Post-test data were collected using the Powe Fatalism Inventory and the Colorectal Cancer Knowledge Questionnaire. Cancer fatalism, knowledge of colorectal cancer, and participation in FOBT. People who viewed the intervention video had a greater decrease in cancer fatalism scores and a greater increase in knowledge of colorectal cancer scores than the control group. Both groups had greater than 60% participation in FOBT. Telling the Story ... To Live is God's Will is an effective, self-contained, cost-effective intervention to decrease cancer fatalism and increase knowledge of colorectal cancer. The video was as effective as the ACS video on colorectal cancer in increasing participation in FOBT among rural elders. But, because Telling the Story ... To Live is God's Will also decreases cancer fatalism and increases knowledge, the potential exists for the increased screening behaviors to be maintained over time. Showing the video in waiting areas of community health centers to facilitate the discussion
Full Text Available Spinal injury following direct loading of the head and neck is a rare sequel of bicycle crashes. Fatal head injuries following bicycle crashes have been described in great detail and safety measures such as bicycle helmets have been developed accordingly. Less frequently, however, potentially severe cervical spine injuries have been described. We present the case of a middle-aged female who sustained an ultimately fatal cervical spine injury following a collision with a car whilst biking wearing a helmet. We discuss the literature regarding the protective effects of bicycle helmets, the relevance to cervical spine injury and legislation on mandatory use of helmets for injury prevention.
Two modeling studies were conducted to simulate the effect of fallout shelters on the outcome of a massive countervalue nuclear exchange between the Soviet Union and the United States. One was to determine the number of nuclear weapons required to mount an effective fallout attack against a country with dispersed population; the other was to determine the number of expected US fatalities resulting from a countervalue attack against US urban population centers. The results of these studies indicate that the number of weapons required to mount such an attack depends on the adequacy of the shelter system and that the evacuation of urban populations can substantially reduce expected fatality levels

We report a case of infant death due to scurvy, which is very rare in Japan. We initially had little knowledge of the disease and suspected that the bleeding in the body was caused by domestic violence. The case did not fall under the category of the battered child syndrome but the death was caused by ignorance with respect to child care. In addition the parents usually locked the child alone in a room during the day and this is probably a case of neglect.

We evaluated reports in the literature concerning acute exacerbation (acute lung injury of unknown cause in UIP and other forms of fibrotic interstitial pneumonias. We also evaluated autopsy tissue in this case in order to determine the cause of death in this 64-year-old man, who was initially thought to have an asbestos-related disease. Based on the autopsy findings, this man died as a result of anticoagulation therapy; specifically, the use of Xarelto® (rivaroxaban.

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. © 2015 American Academy of Forensic Sciences.

Fatal Familial Insomnia (FFI) is a genetic prion disease caused by a point mutation in the prion protein gene (PRNP) characterized by prominent thalamic atrophy, diffuse astrogliosis and moderate deposition of PrP Sc in the brain. Here, for the first time, we demonstrate that the olfactory mucosa (OM) of patients with FFI contains trace amount of PrP Sc detectable by PMCA and RT-QuIC. Quantitative PMCA analysis estimated a PrP Sc concentration of about 1 × 10 -14 g/ml. In contrast, PrP Sc was not detected in OM samples from healthy controls and patients affected by other neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease and frontotemporal dementia. These results indicate that the detection limit of these assays is in the order of a single PrP Sc oligomer/molecule with a specificity of 100%.
Full Text Available There is debate on whether vitamin D deficiency is a risk factor for major chronic diseases and premature death or whether observed associations were just confounded by general health status. Here, we review recent results from the Epidemiologische Studie zu Chancen der Verhütung, Früherkennung und optimierten Therapie chronischer Erkrankungen in der älteren Bevölkerung (ESTHER cohort study and the Consortium on Heatlh and Ageing: Network of Cohorts from Europe and the United States (CHANCES that suggest that vitamin D deficiency may not be a risk factor for the development of cardiovascular diseases and cancer but may be a risk factor for fatal instances of these diseases. Furthermore, analyses comprehensively adjusted for the health status showed that the association of vitamin D and mortality was very likely not confounded by general health status. These results suggest that vitamin D could be a marker of resilience to fatality of potentially fatal diseases. Sufficient vitamin D serum concentrations may be needed to regulate the response of the immune system when it is challenged by severe diseases to prevent a fatal course of the disease. If this hypothesis can be verified through basic research studies and adequately designed randomized controlled trials, it could have important public health implications because vitamin D deficiency is very common worldwide, and interventions could be implemented easily.

The purpose of the present study was the analysis of the trends in case fatality rate of acute myocardial infarction (AMI) in Isfahan, Iran. This analysis was performed based on gender, age groups, and type of AMI according to the International Classification of Diseases, version 10, during 2000-2009. Disregarding the Multinational Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA), this cohort study considered all AMI events registered between 2000 and 2009 in 13 hospitals in Isfahan. All patients were followed for 28 days. In order to assess the case fatality rate, the Kaplan-Meier analysis, and to compare survival rate, log-rank test were used. Using the Cox regression model, 28 days case fatality hazard ratio (HR) was calculated. In total, 12,900 patients with first AMI were entered into the study. Among them, 9307 (72.10%) were men and 3593 (27.90%) women. The mean age in all patients increased from 61.36 ± 12.19 in 2000-2001 to 62.15 ± 12.74 in 2008-2009, (P = 0.0070); in women, from 65.38 ± 10.95 to 67.15 ± 11.72 (P = 0.0200), and in men, from 59.75 ± 12.29 to 59.84 ± 12.54 (P = 0.0170),. In addition, the 28 days case fatality rate in 2000-2009 had a steady descending trend. Thus, it decreased from 11.20% in 2000-2001 to 07.90% in 2008-2009; in men, from 09.20% to 06.70%, and in women, from 16.10% to 10.90%. During the study, HR of case fatality rate in 2000-2001 declined; therefore, in 2002-2003, it was 0.93 [95% confidence interval (CI) = 0.77-1.11], in 2004-2005, 0.88 (95% CI = 0.73-1.04), in 2006-2007, 0.67 (95% CI = 0.56-0.82), and in 2008-2009, 0.69 (95% CI = 0.56-0.82). In Isfahan, a reduction was observable in the trend of case fatality rate in both genders and all age groups. Thus, there was a 29.46% reduction in case fatality rate (27.17% in men, 32.29% in women) during the study period.

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.
Full Text Available BACKGROUND: The association between obesity in adults and excess morbidity and mortality is well established, but the health impact throughout adult life of being obese in early adulthood needs elucidation. We investigated somatic morbidity, including fatal morbidity, throughout adulthood in men starting adult life as obese. METHODS: Among 362,200 Danish young men, examined for military service between 1943 and 1977, all obese (defined as BMI≥31.0 kg/m(2, and, as controls, a random 1% sample of the others was identified. In the age range of 18-25 years, there were 1,862 obese, which encompass the men above the 99.5 percentile, and 3,476 controls. Information on morbidity was obtained via national registers. Cox regression models were used to estimate the relative morbidity assessed as first incidence of disease, occurrence of disease in the year preceding death and prevalent disease at time of death. RESULTS: From age 18 through 80 years the obese had an increased risk of becoming diseased by or die from a broad range of diseases. Generally, the incidence of first event, occurrence in the year prior to death, and prevalence at time of death showed the same pattern. As an example, the relative hazard of type 2 diabetes was constant throughout life at 4.9 (95% confidence intervals [CI]: 4.1-5.9, 5.2 (95% CI: 3.6-7.5, and 6.8 (95% CI: 4.6-10.1, respectively. CONCLUSIONS: Our findings strongly support the continued need to avoid beginning adult life as obese, as obese young men experience an increased morbidity, including fatal morbidity, from many diseases throughout life.

Tattoo removal is increasingly required as the number of, particularly young, people acquiring tattoos is increasing. A 21-year-old man is reported who underwent attempted removal of large dragon tattoo utilizing a tattoo machine that injected a phenol-containing solution. At the end of the 3-h procedure, he collapsed and died. At autopsy, large areas of white skin discoloration with focal necrosis and sloughing were present overlying areas of previous tattooing. Histological examination showed collections of eosinophilic fluid with a minimal chronic inflammatory infiltrate in better preserved areas, with focal areas of dermal necrosis. Toxicology was positive for phenol in cardiac blood and liver tissue. There were no underlying organic disease or injuries present which could have caused or contributed to death. This idiosyncratic method of tattoo removal involving subcutaneous injection of phenol had resulted in death most likely from cardiotoxicity. © 2016 American Academy of Forensic Sciences.

Folic acid is B-9 vitamin. Folic acid is prescribed commonly for pregnant women to prevent neural tube defects in the fetus, patients under chemotherapy, pernicious anemia and to reduce the risk of stroke and cardiovascular disease. Acute or chronic ingestion of a large dose of folic acid generally manifests as neurological complications, which are reversible. In this present case, a 23-year-old pregnant woman committed suicide by consuming folic acid tablets and succumbed to death within 36 h. Postmortem toxicological analysis detected folic acid in viscera. Death following acute consumption of folic acid is rare and has been not reported in the literature, to the best of our knowledge. © 2017 American Academy of Forensic Sciences.

Despite significant advances in science, medicine, and technology African American women are more likely to die from breast cancer than Caucasian women. There is a growing body of literature that describes strategies to improve breast cancer screening among African American women. However, data suggest that African American women, compared to Caucasian women, are less likely to participate in regular breast cancer screening. The belief that a diagnosis of cancer will result in death has been identified as a potential barrier to cancer screening in African American population groups. However, research examining the degree to which perceptions of fatalism influence breast cancer screening in culturally and ethnically diverse population groups is scant. This repot describes the outcomes of a study undertaken to examine relationships between perceptions of cancer fatalism and breast cancer screening in African American women. Findings support the postulation that fatalism negatively influences health promoting practices such as breast cancer screening. However, contrary to prior research findings age was observed to be inversely associated with cancer fatalism.

Ethylene glycol (EG) is used in antifreeze and other industrial products. It metabolizes to glycolic acid (GA) and oxalic acid (OX) that cause metabolic acidosis and are mainly responsible for the toxicity of EG. During 2010-2014, EG or GA was found in 25 postmortem cases in Finland. Of these cases, 21 were classified as fatal EG poisonings and 3 were classified as methanol (MeOH) poisonings. In this study, we report the concentrations of EG and GA in postmortem blood and urine samples of fatal EG or mixed MeOH/EG poisonings. In the fatal EG poisonings, the median EG and GA concentrations were 0.87 and 1.6 g/L in blood and 4.3 and 5.3 g/L in urine. The median urine-blood ratios were 3.8 and 3.1 for EG and GA. These results warrant the use of urine as a primary matrix for screening. In EG positive cases, the quantification of both EG and GA in blood is crucial as GA concentration appears to best indicate a fatal poisoning with an approximate threshold of 1.5 g/L. The measurement of urinary OX does not offer much additional value to toxic alcohol screening as it may originate from varying dietary conditions. © The Author 2015.

Compressed air is being used extensively as a source of energy at industries and in daily life. A variety of fatal injuries are caused by improper and ignorant use of compressed air equipments. Many types of injuries due to compressed air are reported in the literature such as colorectal injury, orbital injury, surgical emphysema, and so on. Most of these injuries are accidental in nature. It is documented that 40 pounds per square inch pressure causes fatal injuries to the ear, eyes, lungs, stomach, and intestine. Openings of body are vulnerable to injuries by compressed air. Death due to compressed air injuries is rarely reported. Many cases are treated successfully by conservative or surgical management. Extensive survey of literature revealed no reports of fatal injury to the upper respiratory tract and lungs caused by compressed air. Here, we are reporting a fatal event of accidental death after insertion of compressed air pipe into the mouth. The postmortem findings are corroborated with the history and discussed in detail.

Full Text Available Background: Although the problem of substance use among drivers is not limited to a special part of the world, most published epidemiological reports on this topic is from industrial world.Aim: To determine drug use among Iranian adults who were imprisoned for vehicle accidents with fatality. Methods: This study enrolled 51 Iranian adults who were imprisoned for vehicle accidents with fatality. This sample came from a national survey of prisoners. Data was collected at entry to prisons during the last 4 months of 2008 in 7 prisons in different parts of the country. Self reported drug use was registered. Commercial substance use screening tests were also done. Results: Drug test was positive for opioids, cannabis and both in 37.3%, 2.0% and 13.7%, respectively. 29.4% tested positive for benzodiazepines. Using test introduced 23.5% of our sample as drug users, who had declined to report any drug use. Conclusion: Opioids are the most used illicit drug in the case of vehicle accidents with fatality, however, 20% of users do not declare their use. This high rate of drug use in vehicle accidents with fatality reflects the importance of drug use control as a part of injury prevention in Iran. There might be a need for drug screening after severe car accidents.

Full Text Available Abstract Introduction Dermatomyositis has been described in the setting of lyme infection in only nine previous case reports. Although lyme disease is known to induce typical clinical findings that are observed in various collagen vascular diseases, to our knowledge, we believe that our case is the first presentation of acute lyme disease associated with amyopathic dermatomyositis, which was then followed by severe and fatal interstitial pulmonary fibrosis only two months later. Case presentation We present a case of a 64-year-old African-American man with multiple medical problems who was diagnosed with acute lyme infection after presenting with the pathognomonic rash and confirmatory serology. In spite of appropriate antimicrobial therapy for lyme infection, he developed unexpected amyopathic dermatomyositis and then interstitial lung disease. Conclusions This case illustrates a potential for lyme disease to produce clinical syndromes that may be indistinguishable from primary connective tissue diseases. An atypical and sequential presentation (dermatomyositis and interstitial lung disease of a common disease (lyme infection is discussed. This case illustrates that in patients who are diagnosed with lyme infection who subsequently develop atypical muscular, respiratory or other systemic complaints, the possibility of severe rheumatological and pulmonary complications should be considered.

Trichosporon (T.) asahii can cause superficial skin infections and can be an opportunistic pathogen that produces potentially fatal systemic infections in immunocompromised hosts. We report a case of lower limb infection due to T. asahii in an immunocompetent patient who displayed no evidence of underlying disease. There is a strong possibility that our patient had been colonized at the infection site as part of the normal skin flora. After one-month bed rest due to an accidental fall and fracture of the right shoulder blade, a 61-year-old woman experienced severe edema and redness in the right lower limb and received topical treatment with iodine solution and antibiotics without improvement. She presented at our Outpatient Clinic with cellulitis and lymphedema. Samples collected from the affected areas revealed T. asahii and the patient was referred to a hospital for infectious diseases for appropriate therapy. The patient was treated with wound dressings until she was admitted to our intensive care unit when her general condition abruptly deteriorated. Despite in vitro susceptibility results, therapy with liposomal amphotericin and voriconazole could not change the fatal outcome. Nowadays, physicians must suspect this emerging difficult-to-treat fungal pathogen and treatment must start promptly in these infections.
Full Text Available Abstract Measles, a highly infectious vaccine-preventable viral disease, is potentially fatal. Historically, measles case-fatality ratios (CFRs have been reported to vary from 0.1% in the developed world to as high as 30% in emergency settings. Estimates of the global burden of mortality from measles, critical to prioritizing measles vaccination among other health interventions, are highly sensitive to the CFR estimates used in modeling; however, due to the lack of reliable, up-to-date data, considerable debate exists as to what CFR estimates are appropriate to use. To determine current measles CFRs in high-burden settings without vital registration we have conducted six retrospective measles mortality studies in such settings. This paper examines the methodological challenges of this work and our solutions to these challenges, including the integration of lessons from retrospective all-cause mortality studies into CFR studies, approaches to laboratory confirmation of outbreaks, and means of obtaining a representative sample of case-patients. Our experiences are relevant to those conducting retrospective CFR studies for measles or other diseases, and to those interested in all-cause mortality studies.

Much research on fatalism assumes that fatalistic statements represent a global outlook that conflicts with belief in the efficacy of health behaviours. Other scholars have suggested a more contextual approach, suggesting that fatalism fulfils personal and social functions. This study analyses 96 in-depth lay interviews in the US, most with low-income members of the general public, about four diseases: heart disease, lung cancer, diabetes and depression. Within these interviews, fatalistic statements always occurred alongside statements endorsing the utility of behaviours for protecting health. This usage pattern suggests that these statements may have useful functions, rather than being simply a repudiation of the utility of health choices. We examine four functions that are suggested by previous researchers or by the participants' comments: stress relief, uncertainty management, sense making and (less strongly) face saving. As these themes indicate, individuals often make fatalistic statements to express an understanding of locally or broadly limiting factors for health efficacy, including genes, spiritual agents, prior behaviours, personality, and other factors.

The lethal toxin of Clostridium sordellii (TcsL) evokes severe, mostly fatal disease patterns like toxic shock syndrome in humans and animals. Since this large clostridial toxin-induced severe muscle damaging when injected intramuscularly into mice, we hypothesized that TcsL is also associated with equine atypical myopathy (EAM), a fatal myodystrophy of hitherto unknown etiology. Transmission electron microscopy revealed skeletal and heart muscles of EAM-affected horses to undergo degeneration ultrastructurally similar to the damage found in TcsL-treated mice. Performing immunohistochemistry, myofibers of EAM-affected horses specifically reacted with sera derived from horses with EAM as well as an antibody specific for the N-terminal part of TcsL, while both antibodies failed to bind to the myofibers of either healthy horses or those with other myopathies. The presence of TcsL in myofibers of horses with EAM suggests that it plays a role as trigger or even as lethal factor in this disease. Copyright 2010 Elsevier B.V. All rights reserved.

Full Text Available Introduction: Accidents and assaults (homicides are the leading causes of death among the youth of the United States, accounting for 53.3% of deaths among children aged 1 to19 years. Victim recidivism,defined as repeated visits to the emergency department (ED as a victim of violent trauma, is a significantly growing public health problem. As 5-year mortality rates for recidivism are as high as 20%,it is important to determine whether victims with a history of violent trauma are at increased risk for fatal outcome with their next trauma. We hypothesized that victims of violent trauma who have had 1 prior ED visit for violent trauma will have increased odds of fatal outcome.Methods: A retrospective chart review was conducted for patients presenting with penetrating trauma to the ED from January 1, 1999 to December 31, 2009. All patients between the ages of 15 to 25 years who presented to the ED for any penetrating trauma were included. Patients with prior presentations for penetrating trauma were compared to those patients who were first-time presenters to determine the odds ratio of fatal outcome.Results: Overall, 15,395 patients were treated for traumatic presentations. Of these, 1,044 met inclusion criteria. Demographically, 79.4% were Hispanic, 19.4% were African American, and 0.96% were Caucasian. The average age was 21 years, and 98% of the population was male. One hundred and forty-seven (14% had prior presentations, and 897 (86% did not. Forty of the 147 patients (27%with prior presentations had a fatal outcome as compared to 29 patients of the 868 (3% without prior presentations, with odds ratio of 10.8 (95% confidence interval, 6.4–18.1; Pearson v2, P , 0.001. The 5-year mortality rate for those patients with fatal outcomes was calculated at 16.5%.Conclusion: Patients who had prior ED visits for penetrating trauma were at greater risk for fatal outcomes compared to those with no prior visits. Therefore, trauma-related ED visits might

We report a case of human prion disease of 29 months duration in a 74-year-old Japanese man. The disease started with progressive sleeplessness and dementia. MRI showed gradually progressive cerebral atrophy. Neuronal loss, spongiform change and gliosis were evident in the thalamus and cerebral cortex, as well as in the striatum and amygdaloid nucleus. In the cerebellar cortex, mild-to-moderate depletion of Pukinje cells and spongiform change were observed. Mild neuronal loss in the inferior olivary nucleus was also seen. Immunohistochemistry revealed widespread perivacuolar deposits of abnormal prion protein (PrPsc) in the cerebral cortex, thalamus, basal ganglia, and brainstem, and minimal plaque-like deposits of PrPSc in the cerebellar cortex. In the cerebellar plaque-like deposits, the presence of amyloid fibrils was confirmed ultrastructurally. The entire pathology appeared to lie halfway between those of CJD and fatal insomnia, and further demonstrated the relationship between spongiform degeneration and PrPSc deposits, especially in the diseased thalamus. By immunoblotting, the thalamus was shown to contain the lowest amount of PrPSc among the brain regions examined. The PrPSc of type 2, in which the ratio of the three glycoforms was compatible with that of sporadic fatal insomnia (MM2-thalamic variant) reported previously, was also demonstrated. Analysis of the prion protein gene (PRNP) showed no mutation, and homozygosity for methionine at codon 129. In conclusion, we considered that this patient had been suffering from sporadic, pathologically atypical fatal insomnia.
Full Text Available 【Abstract】Objective: To analyze the injuries of motorcyclists involved in fatal motorcycle frontal crashes. Methods: A survey group involving multi-discipline experts was built to randomly collect data on fatal motor-cycle frontal collision accidents that occurred in Chongqing during 2006-2010. The sampled information included medi-cal or autopsy reports, blood alcohol concentration (BAC level, helmet use, accident witness, field sketch as well as field photos. The motorcyclist injuries were scored accord-ing to the Abbreviated Injury Scale (AIS 2005. The involved riders with a BAC level≥20 mg/ml were attributed to alco-hol use. Data were processed statistically with nonparamet-ric test via software SPSS 11.0. Results: A total of 86 fatal motorcycle frontal crashes were sampled and further analyzed. The age of motorcy-clists enrolled in this investigation showed nominal distri-bution and the middle-aged (30-39 years occupied the high-est percentage of fatalities. There were only 14 motorcyclists (16.3% wearing helmets at the moment of collision. And 12.8% of these motorcyclist crashes were attributable to alcohol use. Impact injury was the main fatal cause, accounting for 72% of motorcyclist deaths, followed by tumbling injury (26% and run-over (2%. Respectively 84%, 22% and 19% of motorcyclists who sustained head, chest and abdominal trauma died. Extremity injury was the most frequently ob-served injury type. Conclusions: This investigation is helpful to build accident prevention programs and develop protection de-vices which may effectively mitigate injuries and prevent deaths following motorcycle frontal collision accidents. Further investigations on motorcycle collision accidents are still needed. Key words: Motorcycles; Mortality; Accidents, traffic; Wounds and injuries

Childhood injuries are a major public health problem worldwide, injuries being the leading cause of death and disability from early childhood through adolescence. To examine the 40-year nationwide trends in the number and incidence of fatal injuries among children aged 0-14 years in Finland, a country with a white European population of 5.3 million. Data were obtained from the Official Cause-of-Death Statistics of Finland during 1971-2010. The main categories for unintentional injury deaths were road traffic injury, water traffic injury, falls, drowning and poisoning. For intentional injury deaths, the main categories were suicide and homicide. In 1971, there were 109 fatal injuries involving girls and 207 involving boys, and in 2010, these numbers were 10 and 16. The corresponding incidence rates (per 100 000 children per year) were 20.1 and 2.3 (girls), and 36.7 and 3.5 (boys). The reduction in fatal injuries was mostly due to fewer unintentional injuries. The greatest decline occurred in the number of fatal motor vehicle injuries: from 57 (girls) and 92 (boys) in 1971 to 5 (girls) and 2 (boys) in 2010. Drownings followed a similar pattern. Violence-related deaths also showed a decreasing trend. In 1971, there were 14 intentional deaths in girls and 15 in boys, while in 2010 these numbers were 0 and 3, respectively. This nationwide study confirms a decline in childhood injury deaths over the last four decades, with the greatest declines occurring in the number of fatal motor vehicle injuries, drownings and intentional injuries.

In the US motor vehicle fuel economy standards were imposed in the late 1970s, in response to the oil crises of that decade. Since then, efforts to increase the standards have not occurred, one reason being the argument that smaller vehicles (which are generally more efficient) are considered less safe. Recent analyses (Energy J.( 2004)) suggests that variance in vehicle weights may be more important than the absolute weights of vehicles in making the highway network less safe. In Europe and other countries, which generally have smaller more efficient vehicle fleets, due to relatively high gasoline taxes, this debate has not occurred. In particular, countries such as Great Britain and Sweden have far safer road transport systems than the US but also have much more efficient vehicle fleets. This suggests that either vehicle weight and size are unimportant or if they have an effect it is small compared to other factors. This paper uses international data to build econometric models that examine whether average vehicle fuel economy has any association with road traffic fatalities, while controlling for other factors that are associated with fatalities. The effect on pedestrian fatalities is also analyzed. Cross-sectional time-series data on traffic fatalities from OECD countries is used and negative binomial regression models are developed using panel data to determine whether any associations are present. Results find that changes in vehicle efficiency are not associated with changes in traffic fatalities, suggesting either that size and weight changes over time have not had a strong effect or are not associated with fuel economy improvements

traumatic brain injury (TBI) is a significant public health problem. Developed countries report a significant increase of TBI in older adults in the past decades. The objective of this study was to investigate the changes in TBI-related mortality in older Austrians (65 years or older) between 1980 and 2012 (33 years) and to identify possible causes for these changes. data from Statistics Austria on mortality in Austria between 1980 and 2012 were screened and data on TBI-related mortality in adults aged 65 and older were extracted and analysed, based on the diagnostic codes of the International Classification of Diseases, 10th and 9th revision. Mortality rates were calculated for 5-year age groups; standardized mortality rates were calculated for the total. Mechanism of injury was analysed for all events, both sexes and individual age groups. between 1980 and 2012, 16,204 people aged 65 or older died from TBI in Austria; 61% of these were male. Fatal TBI cases and mortality rates increased in the oldest age groups (80 years or older). Half of the fatal TBI cases were caused by falls, 22% by traffic accidents and 17% by suicides. Rate of fall-related fatal TBI increased and rate of traffic accident-related fatal TBI decreased with age. preventive measures introduced in the past decades in the developed countries have contributed to a decrease in traffic injuries. However, falls in the older population are on the rise, mainly due to ageing of the population, throughout the reported period. It is important to take preventive measures to stop the epidemics of fall-related TBIs and fatalities in older adults. © The Author 2014.

Surgery followed by radioiodine is a mainstay of treatment for thyroid cancers of follicular origins. However, about 5% of the thyroid cancers are non-operable and/or radioiodine-refractory diseases, which are either locally advanced or metastatic and result in a survival of less than 5 years. How to treat this population of thyroid cancer patients becomes a critical issue requiring further understanding of the tumor's genetic information. We used formalin-fixed paraffin-embedded specimens of 22 fatal thyroid cancers and their corresponding non-tumor parts, if available, to yield genomic DNA, and applied the Ion Torrent™ Personal Genome Machine (IT-PGM) System (Life Technologies), a next generation sequencing technology, to interrogate 740 mutational hotspots in 46 oncogenes. We further validated the results by conventional direct sequencing. We confirmed 21 mutations of 11 oncogenes in the 22 fatal thyroid cancer samples. Among them, the MET p.N375S and MLH1 p.V384D mutations, each was detected in two cases, and has rarely been found to be involved in thyroid cancer pathogenesis before. We also identified homozygous PDGFRA p.V824V mutation in eight out of the 22 cases, while the non-tumor counterparts carried heterozygous PDGFRA p.V824V mutation. We noted that the Ion Torrent technique unfortunately showed high false positive rates for detecting EGFR mutations in thyroid cancers. The extensive genetic studies provide new insights to future targeted therapy in these patients. IT-PGM proved to be valuable for comprehensively searching genetic mutations in potentially fatal thyroid cancers. Copyright © 2017. Published by Elsevier B.V.

Please see the Dedication for more information on Dr Hodder.Abstract: Emergency department clinicians are frequently called upon to assess, diagnose, and stabilize patients who present with acute respiratory failure. This review describes a rapid initial approach to acute respiratory failure in adults, illustrated by two common examples: (1 an airway disease – acute potentially fatal asthma, and (2 a pulmonary parenchymal disease – acute lung injury/acute respiratory distress syndrome. As such patients are usually admitted to hospital, discussion will be focused on those initial management aspects most relevant to the emergency department clinician.Keywords: acute asthma, acute lung injury, ARDS, acute respiratory failure

Zika virus (ZIKV) has recently caused a pandemic disease, and many cases of ZIKV infection in pregnant women resulted in abortion, stillbirth, deaths and congenital defects including microcephaly, which now has been proposed as ZIKV congenital syndrome. This study aimed to investigate the in situ immune response profile and mechanisms of neuronal cell damage in fatal Zika microcephaly cases. Brain tissue samples were collected from 15 cases, including 10 microcephalic ZIKV-positive neonates with fatal outcome and five neonatal control flavivirus-negative neonates that died due to other causes, but with preserved central nervous system (CNS) architecture. In microcephaly cases, the histopathological features of the tissue samples were characterized in three CNS areas (meninges, perivascular space, and parenchyma). The changes found were mainly calcification, necrosis, neuronophagy, gliosis, microglial nodules, and inflammatory infiltration of mononuclear cells. The in situ immune response against ZIKV in the CNS of newborns is complex. Despite the predominant expression of Th2 cytokines, other cytokines such as Th1, Th17, Treg, Th9, and Th22 are involved to a lesser extent, but are still likely to participate in the immunopathogenic mechanisms of neural disease in fatal cases of microcephaly caused by ZIKV.
People tend to fear dread risks, that is, low-probability, high-consequence events, such as the terrorist attack on September 11, 2001. If Americans avoided the dread risk of flying after the attack and instead drove some of the unflown miles, one would expect an increase in traffic fatalities. This hypothesis was tested by analyzing data from the U.S. Department of Transportation for the 3 months following September 11. The analysis suggests that the number of Americans who lost their lives on the road by avoiding the risk of flying was higher than the total number of passengers killed on the four fatal flights. I conclude that informing the public about psychological research concerning dread risks could possibly save lives.

On August 15, 1999, Louisiana's mandatory motorcycle helmet law was repealed. Our primary objective was to determine if the repeal resulted in an increase in motorcyclist morbidity and mortality. We retrospectively evaluated the frequency of helmet use and morbidity and mortality before and after the repeal of the law. Fatality statistics for Louisiana were obtained through the National Highway Safety Traffic Association between 1994 and 2002. Injury statistics were totaled for motorcyclists admitted to Medical Center of Louisiana New Orleans during the same period of time. Statewide, helmet use decreased 21.2% (p helmet law, while locally, helmet use decreased 34.7% (p Motorcycle helmet use decreased significantly and motorcyclist fatality rates increased significantly after repeal of the Louisiana mandatory helmet law.

Numerous studies have documented an overrepresentation of posttraumatic stress disorder in the Latino population. However, the contributing factors to trauma symptomatology among Latinos are not fully understood. The present study examined 112 low-income, Latino outpatients in a mental health clinic to identify culturally relevant variables that predict trauma symptomatology. Fatalism, peritraumatic dissociation, acculturation, and demographic variables were analyzed. Peritraumatic dissociation was found to account for a significant percentage of the variance in trauma symptoms (21%) as measured by the Peritraumatic Dissociative Experiences Questionnaire-Modified and the Trauma Symptom Inventory. Fatalism measured by the Multiphasic Assessment of Cultural Constructs was not found to be significantly associated with symptom severity. Also, acculturation variables did not predict peritraumatic dissociation. Implications of the findings for trauma research and practice are discussed.

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.

Following an explosion, the formation of a large number of high velocity flying fragments, especially from glass panes, is very possible. The velocity, the mass and the shape of these projectiles define their hazardousness.

To study the epidemiology and causes of death in fatal car crashes on Swedish roads in which the victim's vehicle caught fire. The data set is from the Swedish Transport Administrations in-depth studies of fatal crashes 1998-2008. Autopsies from all cases provided data on injuries, toxicological analyses, and cause of death. In total, 181 people died in 133 burning cars, accounting for 5 percent of all deaths in passenger cars, sport utility vehicles, vans, and minibuses during 1998 to 2008. The cause of death for a third of the victims was fire related, as burns and/or smoke inhalation injuries, with no fatal trauma injuries. Twenty-five of these 55 deaths were persons 19 years or younger and included 15 of 18 rear seat deaths. Over half of the 181 deaths were in vehicles that had collided with another vehicle and, of these cases, half were killed in collisions with heavy vehicles. The percentage of drivers with illegal blood alcohol concentrations (27%) and suicides (5.5%) were not higher than in other fatal crashes on Swedish roads. The ignition point of the fire was indicated in only half of the cases and, of those, half started in the engine compartment and one fourth started around the fuel tank or lines. Car fires are a deadly postcrash problem. Reducing this risk would be primarily a responsibility for the automotive industry. A multifactor approach could be considered as follows: risk-reducing design, insulation, reduced flammability in motor compartment fluids and plastics, and automatic fire extinguishing equipment. Inspiration could be found in how, for example, the auto racing and aviation industries handle this problem.

A 64-year-old slaughterhouse worker with advanced non-Hodgkin's lymphoma developed septicemia and pneumonia. Mycoplasma arginini, a wall-free prokaryote found in a variety of domestic animal hosts, was repeatedly isolated from blood and bronchial washings from the patient. Immunosuppression, in part caused by hypogammaglobulinemia, probably played a key role in predisposing the patient to a fatal infection. This case suggests that animal mycoplasmas should be considered in the list of infectious agents acquired by immunosuppressed hosts.

A scuba diving fatality usually involves a series of related events culminating in death. Several studies have utilised a chain of events-type analysis (CEA) to isolate and better understand the accident sequence in order to facilitate the creation of relevant countermeasures. The aim of this research was to further develop and better define a process for performing a CEA to reduce potential subjectivity and increase consistency between analysts. To develop more comprehensive and better-defined criteria, existing criteria were modified and a template was created and tested using a CEA. Modifications comprised addition of a category for pre-disposing factors, expansion of criteria for the triggers and disabling agents present during the incident, and more specific inclusion criteria to better encompass a dataset of 56 fatalities. Four investigators (raters) used both the previous criteria and this template, in randomly assigned order, to examine a sample of 13 scuba diver deaths. Individual results were scored against the group consensus for the CEA. Raters' agreement consistency was compared using the Index of Concordance and intra-class correlation coefficients (ICC). The template is presented. The index of concordance between the raters increased from 62% (194⁄312) using the previous criteria to 82% (257⁄312) with use of this template indicating a substantially higher inter-rater agreement when allocating criteria. The agreement in scoring with and without template use was also quantified by ICC which were generally graded as low, illustrating a substantial change in consistency of scoring before and after template use. The template for a CEA for a scuba diving fatality improves consistency of interpretation between users and may improve comparability of diving fatality reports.

There are few data available on which to estimate the risk of death for Australian divers. This report estimates the risk of a scuba diving fatality for Australian residents, international tourists diving in Queensland, and clients of a large Victorian dive operator. Numerators for the estimates were obtained from the Divers Alert Network Asia-Pacific dive fatality database. Denominators were derived from three sources: Participation in Exercise, Recreation and Sport Surveys, 2001-2010 (Australian resident diving activity data); Tourism Research Australia surveys of international visitors to Queensland 2006-2014 and a dive operator in Victoria 2007-2014. Annual fatality rates (AFR) and 95% confidence intervals (95% CI) were calculated using an exact binomial test. Estimated AFRs were: 0.48 (0.37-0.59) deaths per 100,000 dives, or 8.73 (6.85-10.96) deaths per 100,000 divers for Australian residents; 0.12 (0.05-0.25) deaths per 100,000 dives, or 0.46 (0.20-0.91) deaths per 100,000 divers for international visitors to Queensland; and 1.64 (0.20-5.93) deaths per 100,000 dives for the dive operator in Victoria. On a per diver basis, Australian residents are estimated to be almost twenty times more likely to die whilst scuba diving than are international visitors to Queensland, or to lower than fourfold on a per dive basis. On a per dive basis, divers in Victoria are fourteen times more likely to die than are Queensland international tourists. Although some of the estimates are based on potentially unreliable denominator data extrapolated from surveys, the diving fatality rates in Australia appear to vary by State, being considerably lower in Queensland than in Victoria. These estimates are similar to or lower than comparable overseas estimates, although reliability of all such measurements varies with study size and accuracy of the data available.

An apparently healthy adult female Chihuahua was presented for elective ovariohysterectomy. After induction of general anesthesia, but prior to the start of the surgery, air was inadvertently administered to the patient via the i.v. fluid line. The patient convulsed, became apneic, arrested, and died despite attempted cardiopulmonary resuscitation. At necropsy, the pericardial sac was incised and filled with water to entirely submerge the intact heart. The right ventricular free wall was punctured, releasing several air bubbles from the right ventricle. Death was attributed to venous air embolism based on the clinical history, gross findings, and paucity of underlying gross and microscopic pathology that might have predisposed the dog to an anesthetic-related death. The discussion of this case includes a review of previously reported veterinary cases of fatal venous air embolism, including the varied mechanisms of embolus formation, the potential impact of pre-existing cardiopulmonary disease, and the methods used to detect emboli. This report outlines the events of fatal iatrogenic venous air embolization and emphasizes the importance of considering this entity in the case of sudden death of a patient with an indwelling catheter in order to pursue either appropriate diagnostic tests or necropsy techniques to aid in the diagnosis.

Ingestion of acid-containing household products either accidentally or for suicide attempt is a common form of intoxication. Hydrochloric acid is widely used as an antirust compound or cleaner in homes and is highly corrosive and generally causes coagulation necrosis which could lead to perforation in the gastrointestinal system. Although hydrochloric acid ingestion is mainly harmful to the gastrointestinal system, it may also cause metabolic acidosis, hemolysis, renal failure, and fatality as well. Cardiovascular manifestations of hydrochloric acid ingestion are extremely rare, and we report a 48-year-old man who died of acute inferolateral myocardial infarction after hydrochloric acid ingestion in a suicide attempt who had no history of coronary artery disease. In conclusion, although cardiovascular manifestations of hydrochloric acid ingestion are extremely rare, the ingestion may still cause myocardial infarction which could be fatal. Physicians dealing with hydrochloric acid ingestion in the ED should be aware of this possibility and always obtain serial electrocardiograms even if the patient has no cardiac complaint.

Studies seeking to identify factors predictive of asthma mortality have relied on information obtained from relatives, other close acquaintances, and doctors who cared for the deceased. We wanted to determine whether asthmatics who have suffered a near-fatal asthma attack (NFA) are similar to asthmatics who have died of asthma with respect to important features, because studies of NFA asthmatics may provide a better insight into causes of asthma death. Such studies would avoid the difficulties associated with seeking information secondhand from proxy informants. Two groups were studied: asthmatics who had suffered a near-fatal asthma attack resulting in a visit to the accident and emergency departments of teaching hospitals (n = 154), and asthmatics certified as dying of asthma who, following panel review, were confirmed to have died from this disease (n = 80). For each case in the two groups, an interview questionnaire was administered to a close acquaintance (household or family member) and to the general practitioner. Both groups shared many important characteristics. Similarities related to: frequency of symptoms; frequency of hospital and intensive care unit admissions for asthma; use of asthma crisis plans; compliance with prescribed medications; quality of personal asthma management; and asthma severity. The two groups also showed similar psychiatric profiles, and similar use of asthma medications on a regular basis and with increased symptoms. However, NFA cases tended to be younger, were more likely to be male, and less likely to have concurrent medical conditions.(ABSTRACT TRUNCATED AT 250 WORDS)

Knowledge of the amount of violence tolerated by the human body is essential when developing and implementing pedestrian safety strategies. When estimating the potential benefits of new countermeasures, the pedestrian fatality risk as a function of impact speed is of particular importance. Although this function has been analysed previously, we state that a proper understanding does not exist. Based on the largest in-depth, pedestrian accident study undertaken to date, we derive an improved risk function for adult pedestrians hit by the front of passenger cars. Our results show far lower fatality risks than generally reported in the traffic safety literature. This discrepancy is primarily explained by sample bias towards severe injury accidents in earlier studies. Nevertheless, a strong dependence on impact speed is found, with the fatality risk at 50 km/h being more than twice as high as the risk at 40 km/h and more than five times higher than the risk at 30 km/h. Our findings should have important implications for the development of pedestrian accident countermeasures worldwide. In particular, the scope of future pedestrian safety policies and research should be broadened to include accidents with impact speeds exceeding 50 km/h.

We report the sudden death of a woman with neurofibromatosis type 1 (NF1). The decedent developed acute respiratory distress and died rapidly despite an emergent cricothyroidotomy. An autopsy with postmortem CT scan was performed to determine the cause of the fatal respiratory collapse and to determine if death was related to neurofibromatosis. Postmortem examination revealed the classical external hallmarks of neurofibromatosis, including innumerable cutaneous neurofibromas. In addition, there was a massive retropharyngeal hematoma with fatal extrinsic compression of the airway. On macroscopic examination A localized 3 cm diameter tumor nodule was found in the soft tissues of the neck. Histologic examination of the nodule revealed a neurofibroma. In addition, histologic sections of the hematoma and surrounding soft tissues revealed plexiform neurofibroma with infiltration of the walls of small blood vessels and of the right vertebral artery. The fatal retropharyngeal hemorrhage was caused by diffuse infiltration of the blood vessels of the neck by plexiform neurofibroma. We concluded that the underlying cause of death was NF1. This case underscores the protean nature of neurofibroma, particularly when diffuse interstitial hemorrhage is present. Infiltration of soft tissues by neurofibroma may only be detectable on histologic examination.

This study aimed to determine whether fatalistic beliefs were associated with elevated levels of glycated hemoglobin (HbA1c) and to establish the role of religiosity in this relationship. A cross-sectional survey was conducted on a sample of 183 Jewish adults with diabetes visiting a large medical center in northern Israel. Self-administered questionnaires assessed level of religiosity, fatalistic beliefs, diabetes management behaviors, and demographic/personal characteristics; laboratory tests were used to measure HbA1c. Multivariate regression indicated that fatalism was significantly associated with HbA1c (β = 0.51, p = 0.01). The association was no longer statistically significant after including self-reported religiosity in the model (β = 0.31, p = 0.13). This phenomenon is likely due to a confounding relationship between the religious/spiritual coping component of the fatalism index and self-reported religiosity (r = 0.69). The results indicate that addressing fatalistic attitudes may be a viable strategy for improving diabetes management, but call for a better understanding of the interplay between religiosity and fatalism in this context.

The purpose of this study was to estimate non-radiological risks of occupational fatalities in Ontario industries. The distribution of high-risk occupations was found to vary widely between the different industries for a number of reasons including the fact that insufficient data in some instances resulted in less than desirable reliability. However, in spite of various data limitations, a number of occupations had above average fatal risk rates in several industries, including Material Handlers and Related, N.E.C. (SOC-9319), Welders and Flame Cutters (SOC-8335), Truck Drivers (SOC-9175) and Mechanics and Repairmen, except Electrical (SOC-8589). The majority of occupations had rates below or close to the industry average; however, between 15% and 30% of the occupations in any given industry had fatal risk rates above the industry average. When the number of workers involved in different occupations was considered, between 18% and 40% of workers were in occupations with above average risk. Recommendations for future work are also provided

Under the Irish Constitution abortion is allowed only where the life of the pregnant woman is at risk. The provision in question, Article 40.3.3 (or the 8th Amendment) has long been criticised for failing to respect women's autonomy, and in Mellet v Ireland, the UN Human Rights Committee found that Amanda Jane Mellet, who travelled to Liverpool to access abortion following a finding that her foetus suffered a fatal abnormality, had suffered a violation of her rights under the International Covenant on Civil and Political Rights (ICCPR). In this commentary I demonstrate the value of Mellet when compared to the possible legal findings in such circumstances under both the Constitution and the European Convention on Human Rights, and argue that the findings are not restricted to cases of fatal foetal abnormality. Rather, the Committee's decision illustrates the suffering that all women in Ireland who travel to access abortion experience, arguably constituting a violation of their right to be free from cruel, inhuman, and degrading treatment. On that reading, Mellet signifies the need to implement a comprehensive rethink of Irish abortion law including, but going beyond, access to abortion in cases of fatal foetal abnormality. © The Author 2016.

Since 1992 the Consultative Committee on Road Traffic Fatalities in Victoria has identified deficiencies and errors in the management of 559 road traffic fatalities in which the patients were alive on arrival of ambulance services. The Committee also assessed the preventability of deaths. Reproducibility of results using its methodology has been shown to be statistically significant. The Committee's findings and recommendations, the latter made in association with the learned Colleges and specialist Societies, led to the establishment of a Ministerial Taskforce on Trauma and Emergency Services. As a consequence, in 2000, a new trauma care system will be implemented in Victoria. This paper presents a case example demonstrating the Committee's methodology. The Committee has two 12 member multidisciplinary evaluative panels. A retrospective evaluation was made of the complete ambulance, hospital and autopsy records of eligible fatalities. The clinical and pathological findings were analysed using a comprehensive data proforma, a narrative summary and the complete records. Resulting multidisciplinary discussion problems were identified and the potential preventability of death was assessed. In the present case example the Committee identified 16 management deficiencies of which 11 were assessed as having contributed to the patient's death; the death, however, was judged to be non-preventable. The presentation of this example demonstrating the Committee's methodology may be of assistance to hospital medical staff undertaking their own major trauma audit.

Socio-cultural factors such as cancer fatalism have been understudied in cancer patients. Women from two cancer centers completed a structured phone survey and an open-ended cognitive interview. Socio-cultural variables of fatalism, hope, and spiritual coping were measured using standardized scales. Older women had significantly higher fatalism scores compared to younger women (p Fatalism rates were low. Ratings of hope and collaborative religious coping were high (m = 20, m = 35, respectively). Qualitative comments confirmed the overall low acceptability of the fatalism measures. Further research is needed to identify measures that are acceptable to newly diagnosed patients.

Cancer fatalism (the belief that death is inevitable when cancer is present) may influence cancer screening practices among older African American women. Little is known about cancer fatalism among younger women. Guided by the Patient/Provider/System Model, this descriptive study compares cancer fatalism and cancer knowledge among African American college students (n = 353) and women from primary care centers (n = 361). Their average age was 29 years. Data were collected using the Powe Fatalism Inventory and breast and cervical cancer knowledge scales. Women at health centers had higher cancer fatalism and lower cancer knowledge. Differences in life experiences may help explain these findings.

Motorcycles vary in design and performance capability, and motorcyclists may select certain motorcycle types based on driving preferences. Conversely, motorcycle performance capability may influence the likelihood of risky driving behaviors such as speeding. Both mechanisms may affect fatal crash risk when examined by motorcycle type. Although it was not possible to estimate the effect of each mechanism, the current study analyzed fatal crash data for evidence of motorcycle type differences in risky driving behaviors and risk of driver death. Street legal motorcycles were classified into 10 types based on design characteristics and then further grouped as cruiser/standard, touring, sport touring, sport/unclad sport, supersport, and all others. For each motorcycle type, driver death rates per 10,000 registered vehicle years and the prevalence of fatal crash characteristics such as speeding were analyzed. Differences among motorcycle types concerning the effect of engine displacement were examined using Poisson regression. Overall, driver death rates for supersport motorcycles were four times as high as those for cruiser/standard motorcycles. Fatally injured supersport drivers were most likely to have been speeding and most likely to have worn helmets, but least likely to have been impaired by alcohol compared with drivers of other motorcycle types. The patterns in driver factors held after accounting for the effects of age and gender. Increased engine displacement was associated with higher driver death rates for each motorcycle type. Strong effects of motorcycle type were observed on driver death rates and on the likelihood of risky driving behaviors such as speeding and alcohol impairment. Although the current study could not completely disentangle the effects of motorcycle type and rider characteristics such as age on driver death rates, the effects of both motorcycle type and rider age on the likelihood of risky driving behaviors were observed among fatally
Full Text Available Introduction. Diagnosis of viral myocarditis, based on the evidence base, is still one of the key problems of the heart disease. The presence of morphological features of the inflammatory process makes it possible to confirm the diagnosis of myocarditis, but, at the same time, the absence of these features is not sufficient to remove this diagnosis. In routine postmortem study of deaths in multidisciplinary (non-infectious hospital myocarditis is stated as a cause of death in 0.2-0.4% of all the autopsies. Mortality in myocarditis depends on the severity of the underlying disease, premorbid background, age and sex composition of the patients. According to different authors, it is very different and ranges from 0.03 to 26%. The aim of the work was to carry out histological and molecular biological studies postmortem material for confirming the etiologic role of herpesviruses with fatal consequences of infectious myocarditis during the observation period 2015-2016 years. Material & methods. The material of pathological heart, vascular endothelium, nerve ganglia, kidneys, liver and pancreas were investigated. Viral antigen detection was performed by fluorescent antibody technique with specific sera labeled with FITC (Dako Corporation, Carpinteria, CA and detection of the viral genome by PCR (in SYNEVO Laboratory. Morphological studies have been conducted in the post-mortem offices of the Kharkov clinical hospitals. Detection of viral genome was performed by PCR using certified commercial kits for detection of nucleotide sequences of herpesviruses «HSV I, II-EPh», «VZV-FL», «EBV-EPh», «CMV-EPh», «HHV VI-Eph», («AmpliSens».

Text mining is a flexible technology that can be applied to numerous different tasks in biology and medicine. We present a system for extracting disease-gene associations from biomedical abstracts. The system consists of a highly efficient dictionary-based tagger for named entity recognition...... of human genes and diseases, which we combine with a scoring scheme that takes into account co-occurrences both within and between sentences. We show that this approach is able to extract half of all manually curated associations with a false positive rate of only 0.16%. Nonetheless, text mining should...... not stand alone, but be combined with other types of evidence. For this reason, we have developed the DISEASES resource, which integrates the results from text mining with manually curated disease-gene associations, cancer mutation data, and genome-wide association studies from existing databases...

Once rare, septic shock (SS) due to disseminated fungal infections has been increasingly reported due to a growing number of immunocompromised patients, but remains rare in non-immune-compromised individuals. In paracoccidioidomycosis, it has been described in only three patients with the severe, acute form of the disease. We describe the development of a refractory, fatal septic shock due to a severe disseminated chronic form of paracoccidioidomycosis in an older woman without any other microbial insults. A striking event in the evolution of her case was the severe depletion of lymphocytes from the peripheral blood and lymphoid organs. Lymphocyte depletion due to apoptosis is described in the late phase of sepsis and can contribute both to immunosuppression and the progression of SS. The possible mechanisms involved in the induction of SS in the chronic form of paracoccidioidomycosis are discussed.
Full Text Available An increased release of serotonin secreted by ileal NETs is thought to be the major factor causing the carcinoid syndrome. However, in acutely arising carcinoid crisis also other vasoactive factors may lead to hazardous fluctuations in blood pressure and bronchial constriction. In rare cases, systemic vasoconstriction can be observed, probably caused by catecholamines or similar acting substances. Here, we report a fatal case of fulminant systemic vasoconstriction possibly caused by catecholamines in a patient with metastasized ileal NET. The vasospasm was detected by CT-angiography, and hemodynamic monitoring revealed a high systemic vascular resistance. Epinephrine, norepinephrine, and chromogranin A levels in plasma were elevated as was the urinary 5-hydroxyindoleacetic acid (5-HIAA. The cause of death was heart failure due to severe circulatory insufficiency. The progression of the tumor disease was confirmed by autopsy.

Lethal outcomes can be expressed as a case fatality ratio (CFR) or as a mortality rate per 100 000 population per year (MR). Population surveillance for community-onset methicillin-sensitive (MSSA) and methicillin-resistant (MRSA) Staphylococcus aureus bacteraemia was conducted in Canada, Australia......, Sweden and Denmark to evaluate 30-day CFR and MR trends between 2000 and 2008. The CFR was 20.3% (MSSA 20.2%, MRSA 22.3%) and MR was 3.4 (MSSA 3.1, MRSA 0.3) per 100 000 per year. Although MSSA CFR was stable the MSSA MR increased; MRSA CFR decreased while its MR remained low during the study. Community......-onset S. aureus bacteraemia, particularly MSSA, is associated with major disease burden. This study highlights complementary information provided by evaluating both CFR and MR....

Intracerebral (i.c.) infection with lymphocytic choriomeningitis virus (LCMV) is one of the most studied models for virus-induced immunopathology, and based on results from perforin-deficient mice, it is currently assumed that fatal disease directly reflects perforin-mediated cell lysis. However...... the outcome of i.c. infection with LCMV. We confirmed that the expansion of virus-specific CD8(+) T cells is unimpaired in perforin-deficient mice. However, despite the fact that the virus-specific CD8(+) effector T cells in perforin-deficient mice are broadly impaired in their effector function, these mice...... invariably succumb to i.c. infection with LCMV strain Armstrong, although a few days later than matched wild-type mice. Upon further investigation, we found that this delay correlates with the delayed recruitment of inflammatory cells to the central nervous system (CNS). However, CD8(+) effector T cells were...

Information seeking is an important behavior for cancer prevention and control, but inequalities in the communication of information about the disease persist. Conceptual models have suggested that low health literacy is a barrier to information seeking, and that fatalistic beliefs about cancer may be a mediator of this relationship. Cancer fatalism can be described as deterministic thoughts about the external causes of the disease, the inability to prevent it, and the inevitability of death at diagnosis. This study aimed to examine the associations between these constructs and sociodemographic factors, and test a mediation model using the American population-representative Health Information and National Trends Survey (HINTS 4), Cycle 3 (n = 2,657). Approximately one third (34%) of the population failed to answer 2/4 health literacy items correctly (limited health literacy). Many participants agreed with the fatalistic beliefs that it seems like everything causes cancer (66%), that one cannot do much to lower his or her chances of getting cancer (29%), and that thinking about cancer makes one automatically think about death (58%). More than half of the population had "ever" sought information about cancer (53%). In analyses adjusted for sociodemographic characteristics and family cancer history, people with limited health literacy were less likely to have ever sought cancer information (odds ratio [OR] = 0.63; 0.42-0.95) and more frequently endorsed the belief that "there's not much you can do . . ." (OR = 1.61; 1.05-2.47). This fatalistic belief partially explained the relationship between health literacy and information seeking in the mediation model (14% mediation). Interventions are needed to address low health literacy and cancer fatalism to increase public interest in cancer-related information. © 2015 Society for Public Health Education.

In South Africa, injuries are the third leading cause of death and disability. Children are especially susceptible to unintentional injuries, especially pedestrian injuries, burns and drowning. Injury risk is informed by children's exposure to adverse environmental circumstances, and individual capacities dependent on developmental maturity. Boys are at greater risk than girls. This study investigates the incidence of fatal childhood injuries as well as sex differences across psychosocial development stages. Data on fatal injuries in Gauteng, South Africa's most populous province, were obtained from the National Injury Mortality Surveillance System. The analysis drew on Erikson's psychosocial theory of development which was used to create meaningful age groups. Age-specific population data from the 2011 Census were used to calculate rates, and significant differences were determined through the generation of risk ratios and confidence intervals. There were 5404 fatal injuries among children in Gauteng from 2008 to 2011. The average age of victims was 8.9 years, and the majority male (65.6%). In infancy, the mortality rates for all injuries and non-traffic unintentional injuries were significantly higher than for the other age groups. Burns were the most common cause of death in infancy and early childhood. Pedestrian injuries accounted for a third of mortality in preschool and school age, and homicide rates were significantly higher in adolescence than in the other developmental stages. For injuries in general, boys had significantly higher mortality rates than girls in all age groups except preschool. The only instance where the mortality rate for girls was significantly higher than for boys was for adolescent ingestion poisoning suicides. The exposure to environmental and social risks is differentially moderated with maturing age and levels of autonomy. The sex of the child also informs risk. The nature of these risks is important when considering child injury

Mutations in the gene for the signal transducer and activator of transcription 1, STAT1, have been shown to be associated with death at an early age due to overwhelming viral infection (complete STAT1 deficiency) or, more commonly, selective deficiencies to mycobacterial or fungal infection (typically heterozygous STAT1 mutations). To define the molecular basis of progressive combined immunodeficiency in a group of patients with fatal infections. We studied a group of unrelated patients who displayed an unusual progressive form of combined immunodeficiency. Whole exome sequencing assisted in confirming a common genetic defect in this group, which consisted of a heterozygous mutation of the STAT1 gene. STAT1 protein level as well as function was assessed, and a detailed evaluation of the immune system, including analysis of thymus tissue, was performed. Patients were found to carry de novo heterozygous mutations in STAT1 encoding T385A, I294T, or C284R amino acid substitutions. STAT1 expression appeared significantly decreased as a result of these changes but not completely absent, with diminished signaling responses. This group display progressive loss in lymphocyte number and function accompanied by increasing autoimmune features as well as severe, fatal infections. These findings show that some heterozygous aberrations of STAT1 can be associated with progressive combined immunodeficiency, quite distinct from the limited susceptibilities to infection previously reported for heterozygous STAT1 mutations. These mutations were not inherited, rather, arose de novo in each case. Accompanied by significant patient mortality, this finding suggests that this class of STAT1 mutation is ultimately fatal due to overwhelming infection.

Full Text Available Objective. To describe the characteristics of non-fatal suicide behaviour (NFSB in a group of patients and to determine factors, if any, that may be associated with repetition of this behaviour. Method. The study included all patients treated for NFSB at Johannesburg Hospital during the period August 2002 - October 2002. The information was gathered by means of a structured questionnaire designed to evaluate characteristics of the behaviour. Results. The study sample comprised 43 patients with NFSB (mean age 29.7 years, range of 16 - 75 years, of whom 26 (60% were female. Sixty-three per cent of the patients overdosed with medication and 33% ingested household poisons. Events that precipitated the event included relationship problems (70%, illness (12%, financial difficulties (9%, and depressed mood (9%. In 65% of patients the behaviour was impulsive. Factors associated with non-fatal repetition included being in the 18 - 30-year age group (76% (χ2 = 6.74, p < 0.05; being female (90% (χ2 = 4.75, p < 0.05; having children (90% (χ2 = 4.72, p < 0.05; a past psychiatric history (50% (χ2 = 4.08, p < 0.05; and the current attempt deemed medically serious (50% (χ2 = 6.67, p < 0.05. Conclusions. NFSB is a major problem in South Africa and the incidence is still increasing. Hospital-based interventions following admission are recommended to reduce repeat attempts in such patients. Significant factors associated with non-fatal repetition include among others, a history of a previous medically serious attempt and/or a known psychiatric illness.

The associations between psychiatric caseness, denial, and self reported measures of handicap and morbidity due to asthma in patients suffering a near fatal attack of asthma have not been fully explored. Seventy seven consecutive subjects who presented to Adelaide teaching hospitals with a near fatal attack of asthma were assessed with a validated semi-structured interview following discharge from hospital. 43% of the patients scored > or = 5 on the GHQ-28 questionnaire. There was a positive correlation between GHQ-28 score and limitation to daily activities due to asthma, and between GHQ-28 score and days lost from work, school or usual daily activities, both of which were retained after adjusting for age and sex. Asthma severity did not show a clear association with GHQ-28 score. The asthmatic patients reported high levels of denial, 57% scoring more than 3 out of 5 on the denial scale of the Illness Behaviour Questionnaire. Presentation with a history of progressive respiratory distress was negatively associated with denial score. This persisted after adjustment for age and sex--that is, those with high denial scores were more likely to report presentation as sudden collapse than progressive respiratory distress. Psychiatric caseness (GHQ score > or = 5) is associated with high levels of morbidity in asthmatic patients who survive a near fatal attack of asthma. High levels of denial in asthmatic subjects may be life threatening. The link between morbidity associated with asthma and psychiatric features, along with other psychosocial issues, warrants further investigation. A broader paradigm than the traditional medical model should be considered when assessing patients with asthma.

Thousands of industrial-scale wind turbines are being built across the world each year to meet the growing demand for sustainable energy. Bats of certain species are dying at wind turbines in unprecedented numbers. Species of bats consistently affected by turbines tend to be those that rely on trees as roosts and most migrate long distances. Although considerable progress has been made in recent years toward better understanding the problem, the causes of bat fatalities at turbines remain unclear. In this synthesis, we review hypothesized causes of bat fatalities at turbines. Hypotheses of cause fall into 2 general categoriesproximate and ultimate. Proximate causes explain the direct means by which bats die at turbines and include collision with towers and rotating blades, and barotrauma. Ultimate causes explain why bats come close to turbines and include 3 general types: random collisions, coincidental collisions, and collisions that result from attraction of bats to turbines. The random collision hypothesis posits that interactions between bats and turbines are random events and that fatalities are representative of the bats present at a site. Coincidental hypotheses posit that certain aspects of bat distribution or behavior put them at risk of collision and include aggregation during migration and seasonal increases in flight activity associated with feeding or mating. A surprising number of attraction hypotheses suggest that bats might be attracted to turbines out of curiosity, misperception, or as potential feeding, roosting, flocking, and mating opportunities. Identifying, prioritizing, and testing hypothesized causes of bat collisions with wind turbines are vital steps toward developing practical solutions to the problem. ?? 2009 American Society of Mammalogists.

Infectious bursal disease (IBD) (Gumboro disease) has been described throughout the world, and the socio-economic significance of the disease is considerable world-wide. Various forms of the disease have been described, but typing remains unclear, since antigenic and pathotypic criteria are used indiscriminately, and the true incidence of different types is difficult to determine. Moreover, the infection, when not fatal, leads to a degree of immunosuppression which is often difficult to measure. Finally, the control measures used are subject to variations, and seldom follow a specific or standardised plan. In the context of expanding international trade, the authors provide an overview of existing knowledge on the subject to enhance available information on the epidemiology of IBD, the identification of reliable viral markers for diagnosis, and the implementation of specific control measures to ensure a global and co-ordinated approach to the disease.

Full Text Available We describe a rare case of fatal disseminated tuberculous peritonitis in a young woman with rapid progressive clinical course following spontaneous abortion of 20-week gestation. Clinical and laboratory findings were initially unremarkable. She underwent diagnostic laparoscopy which revealed numerous tiny implants on the peritoneum and viscera. Histopathology showed chronic caseating granulomas, and the tissue culture grew Mycobacterium tuberculosis. At fifth day of the antituberculous treatment multiorgan failure occurred in terms of pulmonary, hepatic, and renal insufficiency. She developed refractory metabolic acidosis with coagulopathy and pancytopenia, and she died of acute respiratory distress syndrome and septic shock on her twelfth day of hospitalization.

A 19-y old male who intentionally ingested an unknown quantity of Datura stramonium seeds to experience its hallucinogenic effects was found dead. Hyoscyamine and scopolamine were detected in postmortem blood and urine. Blood concentrations of hyoscyamine and scopolamine were 1.1 and 0.2 microg/mL, respectively; in urine only hyoscyamine at 14.2 microg/mL was found. This fatality presents the highest blood concentrations ever reported and confirms that death was due to Datura Stramonium seed ingestion.

The influx of millions of Syrian refugees into Turkey has rapidly changed the population distribution along the Dead Sea Rift and East Anatolian fault zones. In contrast to other countries in the Middle East where refugees are accommodated in camp environments, the majority of displaced individuals in Turkey are integrated into local cities, towns, and villages - placing stress on urban settings and increasing potential exposure to strong earthquake shaking. Yet displaced populations are often unaccounted for in the census-based population models used in earthquake fatality estimations. This study creates a minimally modeled refugee gridded population model and analyzes its impact on semi-empirical fatality estimations across southeast Turkey. Daytime and nighttime fatality estimates were produced for five fault segments at earthquake magnitudes 5.8, 6.4, and 7.0. Baseline fatality estimates calculated from census-based population estimates for the study area varied in scale from tens to thousands of fatalities, with higher death totals in nighttime scenarios. Refugee fatality estimations were analyzed across 500 semi-random building occupancy distributions. Median fatality estimates for refugee populations added non-negligible contributions to earthquake fatalities at four of five fault locations, increasing total fatality estimates by 7-27 %. These findings communicate the necessity of incorporating refugee statistics into earthquake fatality estimations in southeast Turkey and the ongoing importance of placing environmental hazards in their appropriate regional and temporal context.

Full Text Available Prion diseases are neurodegenerative illnesses due to the accumulation of small infectious pathogens containing protein but apparently lacking nucleic acid, which have long incubation periods and progress inexorably once clinical symptoms appear. Prions are uniquely resistant to a number of normal decontaminating procedures. The prionopathies [Kuru, Creutzfeldt-Jakob disease (CJD and its variants, Gerstmann-Sträussler-Scheinker (GSS syndrome and fatal familial insomnia (FFI] result from accumulation of abnormal isoforms of the prion protein in the brains of normal animals on both neuronal and non-neuronal cells. The accumulation of this protein or fragments of it in neurons leads to apoptosis and cell death. There is a strong link between mutations in the gene encoding the normal prion protein in humans (PRNP - located on the short arm of chromosome 20 – and forms of prion disease with a familial predisposition (familial CJD, GSS, FFI. Clinically a prionopathy should be suspected in any case of a fast progressing dementia with ataxia, myoclonus, or in individuals with pathological insomnia associated with dysautonomia. Magnetic resonance imaging, identification of the 14-3-3 protein in the cerebrospinal fluid, tonsil biopsy and genetic studies have been used for in vivo diagnosis circumventing the need of brain biopsy. Histopathology, however, remains the only conclusive method to reach a confident diagnosis. Unfortunately, despite numerous treatment efforts, prionopathies remain short-lasting and fatal diseases.

BACKGROUND: It has been established internationally that road traffic accidents (RTAs) involving older drivers follow clearly different patterns of timing, location and outcomes from those of younger age groups. Older pedestrians are also a vulnerable group and fewer analyses have been undertaken of the phenomenology of their injuries and fatalities. We studied the pattern of pedestrian RTAs in Ireland over a five-year period with the aim of identifying differences between older pedestrians (aged 65 or older) and younger adults. METHODS: We examined the datasets of the Irish National Road Authority (now the Road Safety Authority) from 1998-2002. We analysed patterns of crashes involving older pedestrians (aged 65) and compared them with younger adults (aged 18-64). RESULTS: Older people represented 36% (n = 134) of pedestrian fatalities and 23% of serious injuries while they only account for 19% of total RTAs. Mortality in RTA is more than doubled for older pedestrians compared to younger adults (RR 2.30). Most accidents involving older pedestrians happen in daylight with good visibility (56%) and in good weather conditions (77%). CONCLUSIONS: Older pedestrians are particularly vulnerable in RTAs. These occur more frequently during daylight hours and in good weather conditions. This may point to a need for prevention strategies that are targeted at the traffic environment and other road users rather than at older people.

Problems with lactation can result in hypernatraemic dehydration in the neonate, with potentially severe adverse consequences. This is illustrated in this fatal case of a 10 day old neonate who presented with excessive hypernatraemic dehydration due to insufficient breast milk intake, resulting in cerebral sinus vein thrombosis with cerebral haemorrhage and infarction. Differential diagnosis included excessive sodium intake (through inappropriately mixed formula or house remedies or through hyperaldosteronism) and high water deficit (renal or gastrointestinal losses, nephrogenic or central diabetes insipidus), all of which were ruled out by specific investigations or history. No evidence was found for inborn error of metabolism. The dehydration in this baby, however, was accentuated by trans-epidermal water loss due to an ichthyosiform skin condition. This first ever reported Australian fatality from neonatal hypernatraemic dehydration supports the concern of health care professionals over rising incidences of this entity in exclusively breastfed infants, and should encourage endorsement of improved monitoring of weight loss in newborns and breastfeeding support for their mothers. © 2012 The Authors.

Buprenorphine is an opioid agonist medication that is both safe and effective in the treatment of opioid use disorders and the prevention of opioid overdoses. Despite this, media coverage has highlighted public concerns about the potential safety consequences of buprenorphine misuse and diversion. To address the possible contribution of buprenorphine to overdose mortality, we systematically tested post mortem blood specimens from decedents who had died of an unintentional drug overdoses in 2013. We retrospectively tested consecutive drug overdose cases that occurred from June through October 2013. Cases with available blood specimens were tested for buprenorphine and norbuprenorphine using liquid chromatography-tandem mass spectrometry. Toxicology results were linked to death certificates and case files from New York City Vital Statistics and New York City Office of the Chief Medical Examiner. Of the 98 unintentional drug overdose fatalities tested, only 2 (2.0%) tested positive for buprenorphine metabolites. All 98 unintentional fatalities involved multiple substances. Buprenorphine was infrequently found in drug overdose deaths in New York City. Since the safety and efficacy of buprenorphine are well documented, and overdoses resulting from buprenorphine treatment or diversion are very rare, facilitating access to buprenorphine treatment is strongly recommended.

Mass fatality incidents are always unexpected and put a sudden stress on local response agencies to cooperate and share resources to accomplish tasks that are outside their normal activities. Lines of legal authority are often conflicting when two or more agencies are statutorily in charge. Within the USA, the local coroner system is almost universally delegated as responsible for all involved tasks including body recovery, yet the coroner is almost always the smallest responding agency, with the smallest labour pool from which to draw and the least experience of formal Incident Command System (ICS) procedures at large incidents. This paper explores the many tasks required following a mass fatality incident and the necessity for pre-event written agreements to be negotiated between local, state and federal agencies to ensure that material and personnel can be readily shared and reimbursed without bureaucratic misunderstanding in order to accomplish known objectives. Also explored are potential National Incident Management System conflicts in applying unified command to situations where legal authority and level of commitment are not synonymous.

Due to continuing modernisation, the number of automatic doors in routine use, including powered revolving doors, has increased in recent years. Automatic revolving doors are found mostly in department stores, airports, railway stations and hospitals. Although safety arrangements and guidelines concerning the installation of automatic doors are in existence, their disregard in conjunction with obsolete or incorrect installation can lead to fatal accidents. In this report, a 19-month-old boy is described whose right arm was caught between the elements of an automatic revolving door. As a direct result of rescue attempts, the child's body was drawn further into the narrow gap between elements of the door. To get the boy's body out of the 4-cm-wide gap between the fixed outer wall of the revolving door and the revolving inner, back-up batteries had to be disconnected so as to stop the electrical motor powering the door. Cardiopulmonary resuscitation was begun immediately after the rescue but was unsuccessful; the child was declared dead at the hospital he was taken to. The cause of death was a combination of compression-related skull and brain injury together with thoracic compression. This case shows an outstanding example of the preventive aspect as a special task of forensic medicine. Additionally, it serves as a warning for the correct installation and use of automatic revolving doors. Even so, small children should not use these doors on their own, but only with an alert companion, so as to prevent further fatal accidents of this sort.
Full Text Available Background: Hyperammonemia is known to cause neuronal injury, and can result from valproic acid exposure. Prompt reduction of elevated ammonia levels may prevent permanent neurological injury. We report a case of fatal hyperammonemic brain injury in a woman exposed to valproic acid. Case: A 38-year-old woman with schizoaffective disorder and recent increase in valproic acid dosage presented with somnolence and confusion and rapidly progressed to obtundation. Brain MRI showed diffuse bilateral restricted diffusion in nearly the entire cerebral cortex. She had normal liver function tests but serum ammonia level was severely elevated at 288 µmol/l. Genetic testing showed no mutation in urea cycle enzymes. Despite successful elimination of ammonia with hemodialysis she developed fatal cerebral edema. Conclusion: Cerebral edema secondary to hyperammonemia is potentially reversible if recognized early. Ammonia excretion can be facilitated by initiation of hemodialysis and administration of scavenging agents (sodium phenylacetate and sodium benzoate. Severe hyperammonemia can result from valproic acid exposure even in the absence of hepatotoxicity or inborn errors of metabolism. It is important to check serum ammonia in any patient with encephalopathy who has had recent valproic acid exposure.

Background Updated estimates of measles case fatality rates (CFR) are critical for monitoring progress towards measles elimination goals. India accounted for 36% of total measles deaths occurred globally in 2011. We conducted a retrospective cohort study to estimate measles CFR and identify the risk factors for measles death in Bihar–one of the north Indian states historically known for its low vaccination coverage. Methods We systematically selected 16 of the 31 laboratory-confirmed measles outbreaks occurring in Bihar during 1 October 2011 to 30 April 2012. All households of the villages/urban localities affected by these outbreaks were visited to identify measles cases and deaths. We calculated CFR and used multivariate analysis to identify risk factors for measles death. Results The survey found 3670 measles cases and 28 deaths (CFR: 0.78, 95% confidence interval: 0.47–1.30). CFR was higher among under-five children (1.22%) and children belonging to scheduled castes/tribes (SC/ST, 1.72%). On multivariate analysis, independent risk factors associated with measles death were age Measles CFR in Bihar was low. To further reduce case fatality, health authorities need to ensure that SC/ST are targeted by the immunization programme and that outbreak investigations target for vitamin A treatment of cases in high risk groups such as SC/ST and young children and ensure regular visits by health-workers in affected villages to administer vitamin A to new cases.

Train-person collisions have a significant impact in our society, due to their negative economic and psychological effects. This work aims to study fatalities resulting from train-person collisions in Portugal. A retrospective study was conducted based on the analysis of autopsy reports related to train-person fatalities performed in the North Branch of the National Institute of Legal Medicine and Forensic Sciences. Suicide was responsible for most of the cases, and males were more often involved in train-person collisions than females. Victims, between 40 and 59 years old, were found to be involved in a high percentage (39%) of the cases, and people older than 65 accounted for a significant percentage (40%) of the accidents. No seasonality was observed in suicide cases, but a decrease in accident numbers was registered in summer. Regarding weekday and time of day, afternoon and non-rush hour were the times when most suicides were observed, whereas accidents did not showed a specific weekday or time of day, except for rush hour, during which they were more frequent. Alcohol-positive blood analysis accounting for 25% of the cases. Differences from other European studies were found, which may be related to the different cultures of the countries/regions, as well as to the differences in the railway systems. More extensive studies must be performed in order to develop strategies to prevent train-person collisions.

This paper explores Russia's sensitive nuclear assistance to Iran in an effort to determine why a supplier state might proliferate against its own apparent security interests. The goal is to help readers understand the supply-side dynamics of nuclear proliferation. Through careful reconstruction of the historical narrative, using open source data, this study tests the plausibility of a "fatalistic calculus" explanation, identified by Stephen Sestanovich as a possible driver for Russia's behavior. According to the hypothesis, Russia has cooperated with Iran as a way both to stay in the good graces of a neighbor that is suspected of developing nuclear weapons and to win short-term influence and profits. The paper also examines the role of other factors advanced in the existing supply-side literature, such as economic motives identified by physicist and nonproliferation scholar David Albright. The findings show that bureaucratic, economic and fatalistic factors have each played a role in motivating Russia's cooperation with Iran, with their relative importance shifting over time. Fatalism begets a strategy of Russian "minimaxing," in the lexicon of Russia scholar Robert Freedman, wherein Russia attempts to minimize damage to its relationship with the U.S. while maximizing influence in Iran via nuclear cooperation. Fatalism, as actualized by minimaxing, best explains Russia's behavior after former Russian president Vladmir Putin came to power, when the bureaucratic and economic arguments become less cogent.

The number of latent cancer fatalities estimated in the German Risk Study (Phase A) is analyzed with respect to the essential models. Special attention is given to the following topics: (1) Allocation of the number of fatalities to the population living during the nuclear accident and to persons born afterwards. (2) Contributions of the relevant exposure pathways and types of cancer to the late fatalities. (3) Estimation of the number of fatalities expected within and beyond a distance of 540 km from the site (alteration of model assumptions). (4) Estimation of the relative portion of late fatalities caused by radiation doses below the dose limits of the German radiation protection regulations. Additionaly, the influence of a non-linear dose response function similar to WASH 1400 on the latent cancer fatalities is estimated. The above-mentioned results provide conclusions concerning necessary improvements of models in Phase B of the Risk Study. (orig.) [de

Full Text Available The goal of this paper is to figure out whether Aristotle’s response to the argument for fatalism in De Interpretatione 9 is a success. By “response” it is meant not simply the reasons Aristotle offers to highlight why fatalism does not accord with how we conduct our lives, but also the solution he devises to block the argument for fatalism. This paper finds that a Aristotle’s argument for fatalism is essentially bivalence plus that the truth of a proposition implies necessity, b that Aristotle’s solution is to restrict bivalence, c that this solution is coherent, and d that while this solution does not rule out the possibility of fatalism, it does succeed in blocking the argument for fatalism offered within chapter 9.

We examined the relationship between provider fatalism, a belief that behavior change among HIV-infected patients is unlikely, and HIV-prevention counseling in 16 publicly funded clinics. HIV-seropositive patients (N = 618) completed surveys assessing prevention counseling in the past 6 months. Additionally, 144 interviews were conducted with providers, administrators, and patients to examine beliefs about prevention counseling. We summed the number of fatalistic comments made by providers and administrators in each clinic, and assigned these counts as clinic-level fatalism scores to survey participants. Patients in high fatalism clinics were less likely to report prevention counseling than patients in low fatalism clinics. This difference remained significant even after controlling for clinic characteristics or patients' sexual risk and health status. However, clients in high fatalism clinics were more likely to be White, gay, educated, and older. Provider fatalism is a barrier that must be addressed when implementing HIV-prevention counseling in primary care settings.

Research was undertaken to determine vehicle size parameters influencing driver fatality odds, independent of mass, in two-vehicle collisions. Forty vehicle parameters were evaluated for 1,500 vehicle groupings. Logistic regression analyses show driver factors (belt use, age, drinking) collectively contribute more to fatality odds than vehicle factors, and that mass is the most important vehicular parameter influencing fatality odds for all crash configurations. In car crashes, other vehicle ...

Abstract Rationale: Fatal familial insomnia (FFI) linked to a D178N/129M haplotype mutation in the PRNP gene is the most common genetic prion disease in the Han Chinese population. Here, we describe a Han Chinese patient with FFI who exhibited agrypnia excitata and obstructive apnea. Patient concerns: A 46-year-old man displayed involuntary movements during sleep time, snoring, autonomic nervous system dysfunction, cognitive deficit, brainstem symptoms, myoclonus and ataxia in order within 8 months. The electroencephalogram (EEG) and Magnetic Resonance Imaging (MRI) revealed abnormal changes but without the typical prion disease signs. Diagnoses: After the conduction of Polysomnogram (PSG) and gene detection of PRNP, the patient was diagnosed as FFI. Three others exhibiting the same clinical manifestations were observed in the large family. Interventions: The patient responded temporally well to drugs that strengthening the function of mitochondria. Outcomes: Sudden death occurred after 3 month ever since the diagnoses. The total disease course was 11 months. Lessons: The insomnia in FFI is complex, agrypnia excitata and obstructive apnea can also be indicators for FFI. Polysomnogram is necessary for recognizing the sleep loss when the symptom of insomia is not typical. Improving energy metabolism may be a potential treatment for it. PMID:29245265

Screening and diagnosis of prostate cancer (PCa) is hampered by an inability to predict who has the potential to develop fatal disease and who has indolent cancer. Studies have identified multiple genetic risk loci for PCa incidence, but it is unknown whether they could be used as biomarkers for PCa-specific mortality (PCSM). To examine the association of 47 established PCa risk single-nucleotide polymorphisms (SNPs) with PCSM. We included 10 487 men who had PCa and 11 024 controls, with a median follow-up of 8.3 yr, during which 1053 PCa deaths occurred. The main outcome was PCSM. The risk allele was defined as the allele associated with an increased risk for PCa in the literature. We used Cox proportional hazards regression to calculate the hazard ratios of each SNP with time to progression to PCSM after diagnosis. We also used logistic regression to calculate odds ratios for each risk SNP, comparing fatal PCa cases to controls. Among the cases, we found that 8 of the 47 SNPs were significantly associated (pPCa, but most did not differentiate between fatal and nonfatal PCa. Rs11672691 and rs10993994 were associated with both fatal and nonfatal PCa, while rs6465657, rs7127900, rs2735839, and rs13385191 were associated with nonfatal PCa only. Eight established risk loci were associated with progression to PCSM after diagnosis. Twenty-two SNPs were associated with fatal PCa incidence, but most did not differentiate between fatal and nonfatal PCa. The relatively small magnitudes of the associations do not translate well into risk prediction, but these findings merit further follow-up, because they may yield important clues about the complex biology of fatal PCa. In this report, we assessed whether established PCa risk variants could predict PCSM. We found eight risk variants associated with PCSM: One predicted an increased risk of PCSM, while seven were associated with decreased risk. Larger studies that focus on fatal PCa are needed to identify more markers that

Although landscape and horticultural services workers have high injury and illness rates, little is known about fatalities in this industry. Census of Fatal Occupational Injuries and Current Population Survey data were analyzed to determine fatality rates and causes of landscaping deaths from 1992 to 2001. There were 1,101 fatalities during the 10-year period and the average fatality rate was 13.50 deaths per 100,000 full-time employees. In 2001, the landscaping fatality rate was 3.33 (95% CI 2.84-3.91) times the all industry rate. The leading causes of death were transportation incidents (27%), contact with objects or equipment (27%), falls (24%), exposure to harmful substances and environments (18%), and assaults and violent acts (4%). The fatality rate for African American landscapers was 1.51 (95% CI 1.25-1.83) times the rate for white workers. Fatalities were also common among self-employed, small business, and young landscapers. Landscaping workers are at increased risk of fatal injury. Further research is needed to characterize industry hazards. Published 2008 Wiley-Liss, Inc.
The farming and agricultural sector remains one of Ireland’s primary industries. Fatality rates remain higher than the European average. The aim of this study was to analyze the national trend in hospital in-patient admissions for farmyard related fractures and related fatalities in Ireland from 2005 to 2014. Relevant socioeconomic trends were used for comparison. There were 2,064 farm-related fractures and 187 fatalities recorded over the same period. Despite a decrease in incidence of farmyard fractures over 2005-2014, fatality rates have increased indicating the alarming continued occupational hazards and severity of sustained injuries.

Motor vehicle accidents are the leading cause of death among young adults. Although automobile fatalities have declined in recent years, motorcycle fatalities are rapidly increasing. The purpose of our research was to quantify the relationship between changing fuel prices and motorcycle fatalities. Our findings suggest that people increasingly rely on motorcycles to reduce their fuel costs in response to rising gasoline prices. We estimate that use of motorcycles and scooters instead of 4-wheeled vehicles results in over 1500 additional motorcycle fatalities annually for each dollar increase in gas prices. Motorcycle safety should receive more attention as a leading public health issue. PMID:19696374

Fatalism has been associated with non-adherence to health behavior in the past. This study compared fatalism of Chinese and Korean immigrants with native-born Caucasians (N = 309) and examined whether the relationship between fatalism and exercise, nutrition and medical screening would be moderated by ethnicity. Chinese reported higher fatalism than Caucasians and Koreans. Higher fatalism was associated with greater exercise among Chinese and Koreans, but less reported exercise among Caucasians. Caucasian participants had higher scores for nutrition and medical screening compared with Chinese and Korean immigrants. These findings indicate that fatalism is more prevalent among Chinese immigrants; however, there is no evidence of a detrimental effect of fatalism on exercise, nutrition or medical screening among the Asian immigrants. Caucasians with higher fatalism may be at greater risk of future illnesses, given the association between fatalism and sedentary behavior in this group. Differences between cultural groups in the adoption of health behavior justify the development and assessment of targeted interventions to optimize health promoting behaviors.

To examine beliefs about HIV/AIDS of rural Malians and to measure their level of fatalism in context of HIV/AIDS and prevention behaviors. Descriptive, correlational. An AIDS Knowledge and Beliefs survey and the Powe Fatalism Inventory (PFI)-HIV/AIDS version were administered to a convenience sample of 84 people at three health center maternity clinics in southeastern Mali, West Africa. The sample's HIV/AIDS fatalism mean was 9.2 on a 15-point scale, with an internal consistency of .89. Health workers and more educated participants had significantly lower fatalism scores. Fatalism also varied by the combination of gender and ethnicity. People who believed that AIDS was not real, was a punishment from God, was fabricated by the West, was a curse, and that it was taboo to talk about AIDS had higher fatalism means. None of the prevention indicators were significantly related to fatalism scores. These rural Malians had a high overall fatalism mean and their beliefs about AIDS based on traditional culture may affect prevention behaviors. More research is needed to understand the influence of fatalism on prevention behaviors.

To assess the association between insomnia symptoms and risk of fatal unintentional injuries. Population-based prospective cohort study with a mean follow-up of 14 y, linking health survey data with information on insomnia symptoms to the National Cause of Death Registry. Nord-Trøndelag County, Norway. A total of 54,399 men and women 20-89 y of age who participated in the Nord-Trøndelag Health Study between 1995 and 1997. N/A. There were 277 unintentional fatal injuries, including 57 fatal motor vehicle injuries during follow-up. There was a dose-dependent association between the number of insomnia symptoms and risk of unintentional fatal injuries (P for trend 0.001) and fatal motor vehicle injuries (P for trend 0.023), respectively. The proportion of unintentional fatal injuries cases that could have been prevented in the absence of difficulties initiating sleep, difficulties maintaining sleep, and having a feeling of nonrestorative sleep were 8%, 9%, and 8%, respectively. The corresponding estimates for motor vehicle injuries were 34%, 11%, and 10%. Insomnia is a major contributor to both unintentional fatal injuries in general as well as fatal motor vehicle injuries. Increasing public health awareness about insomnia and identifying persons with insomnia may be important in preventing unintentional fatal injuries.

To evaluate motor vehicle crash fatality rates in the first 2 states with recreational marijuana legalization and compare them with motor vehicle crash fatality rates in similar states without recreational marijuana legalization. We used the US Fatality Analysis Reporting System to determine the annual numbers of motor vehicle crash fatalities between 2009 and 2015 in Washington, Colorado, and 8 control states. We compared year-over-year changes in motor vehicle crash fatality rates (per billion vehicle miles traveled) before and after recreational marijuana legalization with a difference-in-differences approach that controlled for underlying time trends and state-specific population, economic, and traffic characteristics. Pre-recreational marijuana legalization annual changes in motor vehicle crash fatality rates for Washington and Colorado were similar to those for the control states. Post-recreational marijuana legalization changes in motor vehicle crash fatality rates for Washington and Colorado also did not significantly differ from those for the control states (adjusted difference-in-differences coefficient = +0.2 fatalities/billion vehicle miles traveled; 95% confidence interval = -0.4, +0.9). Three years after recreational marijuana legalization, changes in motor vehicle crash fatality rates for Washington and Colorado were not statistically different from those in similar states without recreational marijuana legalization. Future studies over a longer time remain warranted.

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

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. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Bordetella bronchiseptica frequently causes nonfatal tracheobronchitis, but its role in fatal pneumonia is less recognized. Our study evaluated histologic identification of cilia-associated bacteria as a method for diagnosis of B. bronchiseptica pneumonia. Cases of fatal bronchopneumonia were studied retrospectively, excluding neonates and cases of aspiration pneumonia, minor lung lesions, or autolysis. The study population comprised 36 canine and 31 feline cases of bronchopneumonia. B. bronchiseptica was identified in 8 of 36 canine and 14 of 31 feline cases based on immunohistochemistry (IHC) using serum from a rabbit hyperimmunized with pertactin, PCR testing (Fla2/Fla12), and/or bacterial culture data when available. Of these, IHC was positive in 4 canine and 7 feline cases, PCR was positive in 8 canine and 14 feline cases, and B. bronchiseptica was isolated in 2 of 5 canine and 3 of 9 feline cases tested. Examination of histologic sections stained with hematoxylin and eosin revealed bronchial cilia-associated bacteria in 4 of 36 canine and 5 of 31 feline cases; these were all positive by IHC and PCR. The presence of cilia-associated bacteria had been noted in the pathology report for only 2 of these 9 cases. Thus, the presence of cilia-associated bacteria seems frequently overlooked by pathologists, but is a diagnostically significant feature of B. bronchiseptica pneumonia. A specific diagnosis of B. bronchiseptica pneumonia is important because it suggests primary or opportunistic bacterial pneumonia rather than aspiration pneumonia, and because of the risk of animal-to-animal transmission of B. bronchiseptica, the availability of vaccines for disease prevention, and the potential zoonotic risk to immunocompromised pet owners. © 2016 The Author(s).

Once malaria occurs, deaths can be prevented by prompt treatment with relatively affordable and efficacious drugs. Yet this goal is elusive in Africa. The paradox of a continuing but easily preventable cause of high mortality raises important questions for policy makers concerning care-seeking and access to health systems. Although patterns of care-seeking during uncomplicated malaria episodes are well known, studies in cases of fatal malaria are rare. Care-seeking behaviours may differ between these groups. This study documents care-seeking events in 320 children less than five years of age with fatal malaria seen between 1999 and 2001 during over 240,000 person-years of follow-up in a stable perennial malaria transmission setting in southern Tanzania. Accounts of care-seeking recorded in verbal autopsy histories were analysed to determine providers attended and the sequence of choices made as the patients' condition deteriorated. As first resort to care, 78.7% of malaria-attributable deaths used modern biomedical care in the form of antimalarial pharmaceuticals from shops or government or non-governmental heath facilities, 9.4% used initial traditional care at home or from traditional practitioners and 11.9% sought no care of any kind. There were no differences in patterns of choice by sex of the child, sex of the head of the household, socioeconomic status of the household or presence or absence of convulsions. In malaria deaths of all ages who sought care more than once, modern care was included in the first or second resort to care in 90.0% and 99.4% with and without convulsions respectively. In this study of fatal malaria in southern Tanzania, biomedical care is the preferred choice of an overwhelming majority of suspected malaria cases, even those complicated by convulsions. Traditional care is no longer a significant delaying factor. To reduce mortality further will require greater emphasis on recognizing danger signs at home, prompter care

We present the case of a windblown beach umbrella inflicting fatal penetrating blunt force to the chest of a 55-year-old female beachgoer. A postmortem examination and detailed case history review were performed which revealed left ventricular trauma, determined to be the cause of death. Using recorded wind speeds from the date of the incident and the weight of the umbrella, we were able to calculate the pressure with which the umbrella struck the victim to be 16,000 PSI. Witness reports, medical records, scene details, and examination of a rental beach umbrella allowed the forensic pathologist to conclude that the object causing this woman's death was a windblown beach umbrella. © 2018 American Academy of Forensic Sciences.
Full Text Available This was a case of a 35-year-old man with mediastinal mass requiring computed tomography (CT-guided biopsy for tissue diagnosis. A posterior approach with an 18-gauge biopsy needle was used to obtain tissue sample. Post biopsy, patient condition deteriorated and multiphase CT study detected active bleeding in arterial phase at the biopsy site with massive hemothorax. Subsequent angiography showed arterial bleeder arising from the apical branch of the right pulmonary artery. Selective endovascular embolization with NBCA (n-Butyl cyanoacrylate was successful. Patient survived the complication. The case highlighted a rare complication in a common radiology procedure and the value of the interventional radiology unit in avoiding a fatal outcome.

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.
Full Text Available Toxoplasma gondii can infect nearly all warm-blooded animals. We report an acute fatal T. gondii infection in the endangered giant panda (Ailuropoda melanoleuca in a zoo in China, characterized by acute gastroenteritis and respiratory symptoms. T. gondii infection was confirmed by immunological and molecular methods. Multilocus nested PCR-RFLP revealed clonal type I at the SAG1 and c29-2 loci, clonal type II at the SAG2, BTUB, GRA6, c22-8, and L358 loci, and clonal type III at the alternative SAG2 and SAG3 loci, thus, a potential new genotype of T. gondii in the giant panda. Other possible pathogens were not detected. To our knowledge, this is the first report of clinical toxoplasmosis in a giant panda.

Full Text Available Family violence represents an especially dangerous social form of violence by means of which the rights of an individual – a member of a family – to live, to have psychic, physical and sexual integrity, freedom, security and human dignity, have been violated. The term marriage violence entails every form of physical, sexual, psychic and economic abuse of women by husbands or illegitimate partner. The family violence represents a widespread form of crime, and since it has become dramatic and dynamic during the recent years, the need for a direct forensic processing of the violence consequences within this specific and sensitive social group has arisen. In accordance with what has been outlined above, three cases of extreme, systematic and continuous marriage violence with fatal consequences of the abused women, whose bodies have been abducted at the Forensics Institute in Nis, have been presented in this paper.

Among the operators killed one fifth were illegally operating the motorcycle. A remarkable...... statistical difference in distribution of accidents involved motorcycles and the total distribution of motorcycles in the county was reported, thus finding an over-representation of heavy motorcycles in the present study. No important differences were found in the distribution of type of accidents compared...... to other studies. In the present study all but one victim were tested for blood-alcohol concentration (BAC). The results differ from previous studies in as much as 50% of the killed operators of an accident involving motorcycles had a BAC above 0.08%. The reported distribution by age, licensing experience...

In this article, we conceptualised fatalism as a set of health beliefs that encompass the dimensions of predetermination, luck and pessimism. A 20-item scale was developed as a measurement instrument. Confirmatory factor analyses were performed to test the dimensionality of the scale. Three external variables (i.e. genetic determinism, perceived benefits of lifestyle change and intention to engage in healthy behaviour) were used as reference variables to test the construct validity of the scale. Data from a web-based national survey (N = 1218) showed that the scale was unidimensional on the second order, and with good reliability (alpha = 0.88). The relationships between the external variables and the first- and second-order factors provided evidence of the scale's external consistency and construct validity.

Cosmetic procedures are common and utilize many techniques to obtain aesthetically good outcomes for patient satisfaction with acceptable safety standards. Cosmetic procedures that involve the gluteal region are becoming increasingly popular as various procedures can target the gluteal region such as liposuction, tumescent liposuction, cosmetic filler injections, autologous fat transfer, depot drug delivery, and implants. Complications of cosmetic gluteal procedures can be localized or systemic with systemic complications being responsible for most deaths. These reported systemic complications include sepsis, thromboembolism, fat embolism with or without fat embolism syndrome, macroscopic fat embolism, anesthesia-related and blood volume abnormalities. We herein report 10 deaths due to elective gluteal cosmetic procedures. Autologous fat transfer (fat grafting, lipoinjection) following liposuction resulted in 8 of 10 fatal outcomes of the gluteal aesthetic procedures. A comprehensive discussion of gluteal anatomy, gluteal contouring procedures, and the approach to such cases is presented along with the autopsy findings of the reported cases. © 2018 American Academy of Forensic Sciences.

The number of light aircraft (less than 5,700) in the developing world is small compared to those in the West, and little information on aviation accidents is readily available from developing countries. Papua New Guinea, enjoys a priviledged position, since aviation was introduced early and much of the country was opened through flying. During the period of Australian trusteeship until independence in 1975, the Australian Department of Transport applied its own rigorous standards to aviation in Papua New Guinea, a policy continued by the present Civil Aviation Agency. As a result of tight supervisory controls, accurate statistics on accidents are available, from which comparisons with other countries can be made. A study has been made of fatal light aircraft accidents in Papua New Guinea. Some of the Medical problems involved in accident prevention in a developing country are discussed.

Pheniramine maleate is an easily accessible, over-the-counterantihistaminic, which is frequently involved in overdoses. Pheniramine has antimuscarinic effect causing tachycardia, dilated pupils, urinary retention, and dry flushed skin, and decreased bowel sounds, confusion, mild increase in body temperature, cardiac arrhythmias, and seizures at lethal doses. It has not been implicated as an important cause of rhabdomyolysis and acute kidney injury (AKI). Rhabdomyolysis causing AKI is rarely reported in the literature. This case report emphasizes the occurrence of nontraumatic rhabdomyolysis in pheniramine maleate overdose which required hemodialysis. Since there is a lack of a specific antidote, treatment is mainly symptomatic and supportive. We report a fatal case of a young male with a very high dose of consumption of pheniramine maleate (4.077 g), which was complicated by seizures, respiratory depression, nontraumatic rhabdomyolysis, and AKI. Despite hemodialysis, ventilator support, and other intensive supportive care, patient could not survive and death ensued due to multiorgan dysfunction syndrome.
