    Dengue haemorrhagic fever (DHF) is recognized as a leading cause of hospitalization and death among children in many Southeast Asian countries. This study reviews the case fatality rates of DHF cases admitted to a referral hospital in Cebu (Philippines) over the past 5 years. Information on patients 14 years old or younger admitted from 1 January 1997 to 31 December 2001 with the final clinical diagnosis of DHF was collated and analysed. Case fatality rates were compared before and after a standardized management protocol was implemented by the healthcare staff and after introduction of revisions to that protocol. The case fatality rate during the 2-year periods prior and after introduction of the management protocol decreased significantly from 197/2644 (7.45%) to 39/1182 (3.30%) (P < 0.01). Following the introduction of revisions to the protocol, the case fatality was reduced even further to 52/1697 (3.06%) (P = 0.7). In this government hospital the introduction of a standardized management protocol for DHF was associated with a significant improvement in the case fatality rate of hospitalized children with clinically diagnosed DHF. However, compared with reports from hospitals in other dengue-endemic countries, the improvement has been slow. Possible ways to decrease fatality rates further have been identified.

    Background: There are few diverse studies that have reported the case fatality rates of different methods of suicide, none of them are originated from developing countries. The aim of the present article is to report the case fatality rates of different methods of suicide in Ilam province of Iran. Materials and Methods: Data on 611 cases of suicide and 1807 cases of deliberate self harm (DSH) that were recorded in a comprehensive registry during 1995 through 2002 were analyzed for both genders together and for males and females, separately. Findings: For both genders together, the two most fatal methods were hanging (75.4%) and self-immolation (68.3%); for males, hanging (76.3%) and self-immolation (64.7%); and for females, firearms (75%) and hanging (73.7%), respectively. The least fatal methods for both genders together and for females and males separately were drug ingestion and cutting. Conclusion: The results of present study, which for the first time has reported the case fatality rates of suicide methods in a developing world, would not only help to better plan the local suicide prevention strategies and clinical assessment of suicidal cases but to shed light on overall understanding of this mysterious human phenomenon.

    Objective: To compare injury case fatality rates in the United States (US) with New Zealand (NZ) to guide future information collection, research, and evaluation. Design: Using NZ (1992–96) and US (1996–98) mortality censuses, NZ national 1992–96 hospital discharge censuses, and US 1996–98 National Hospital Discharge Survey data, the authors compared case fatality rates by mechanism and intent of injury and age group. The analysis was restricted to severe injuries (AIS⩾3). Subjects: NZ (1992–96) and US (1996–98) populations. Main outcome measures: Ratio of case fatality rates in NZ versus the US (RCFR(NZ:US)). Results: Overall, among cases meeting the study criteria, unintentional injuries were 1.57 times more likely fatal in NZ and intentional assault injuries were 1.14 times more likely to be fatal in the US. Firearms were involved in 50% of US assaults versus 8% of NZ assaults. By mechanism, cutting/piercing injuries were 1.86, firearm injuries were 1.41, and motor vehicle injuries were 1.44 times more to be likely fatal in NZ. Natural/environmental injuries (RCFRNZ:US = 0.57), unintentional poisonings (RCFRNZ:US = 0.26), and unintentional suffocations (RCFRNZ:US = 0.67) were significantly more likely to be fatal in the US. Conclusions: Possible reasons for the observed results include: differences in geography and proportion of population in rural areas, trauma system differences, road design and vehicle types, seat belt use, larger role of firearms in US assaults, coding practices, policies, and environmental factors. Disparities evoke hypotheses to test in future research that will guide priority setting and intervention. PMID:15805434

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

  7. Do escape mutants explain rapid increases in dengue case-fatality rates within epidemics?

    During the Cuban dengue epidemics of 1981 and 1997, significant monthly increases were observed in the proportion of total cases that presented as dengue haemorrhagic fever or dengue shock syndrome (DHF/DSS), and in case-fatality rates for both dengue fever and DHF/DSS. We believe that theses increases can be explained by the hypothesis that some of the population of antibodies against dengue 1 virus raised after natural primary infections react with "neutralisation" determinants found on dengue 2 viruses. These heterotypic antibodies do not prevent secondary dengue 2 infections, but serve to down-regulate the disease to mild illness or symptomless infections. A population of dengue 2 viruses that replicates in dengue-1-immune hosts escape heterotypic neutralisation. When inoculated into a new dengue-1-immune host, these viruses are free to interact with the more abundant infection-enhancing antibodies to produce severe disease.

    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.

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

    BACKGROUND 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. METHODS 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. RESULTS 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). CONCLUSION 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. PMID:26478731

    Information is lacking on the integrated evaluation of mortality rates in healthcare-associated infections (HAIs). Our aim was to differentiate the risk factors responsible for the incidence from those for the case-fatality rates in association with HAIs. We therefore examined the time trends of both incidence and case-fatality rates over a 20-year period at a tertiary-care teaching medical centre in Taiwan and the mortality rate was expressed as the product of the incidence rate and the case-fatality rate. During the study period the overall mortality rate fell from 0·46 to 0·32 deaths/1000 patient-days and the incidence rate fell from 3·41 to 2·31/1000 patient-days, but the case-fatality rate increased marginally from 13·5% to 14·0%. The independent risk factors associated with incidence of HAIs were age, gender, infection site, admission type, and department of hospitalization. Significant prognostic factors for HAI case-fatality were age, infection site, intensive care, and clinical department. We conclude that the decreasing trend for the HAI mortality rate was accompanied by a significant decline in the incidence rate and this was offset by a slightly increasing trend in the case-fatality rate. This deconstruction approach could provide further insights into the underlying complex causes of mortality for HAIs.

    Road traffic collisions (RTCs) are one of the most common preventable causes of death and disability worldwide. We investigated changes in numbers of motor vehicles, case fatality rate, and crash injury rate for the most present recorded year (2002) 5 and 10 years before that in the United Kingdom (U.K.) and Sri Lanka (SL). We also investigated environmental and individual factors impacting patients at South Birmingham Trauma Unit, U.K. and Colombo General Hospital, SL. We conducted a descriptive cross-sectional study (both quantitative and qualitative). Over the 10-year period, numbers of motor vehicles have risen in both countries; the crash injury remained stable in both countries. Case fatality rate (far higher) in SL has decreased, as in the U.K.. Three hundred and twenty-five patients took part in the survey in SL, with 83 in the U.K. In the categories investigated, including patient demographics, RTC environment, visual impairment, pedestrian and driver factors, the majority of results were significantly different between the two countries. Target factors such as inadequate street lighting, visual impairment, speeding, and not wearing seatbelts at time of accident were identified, and recommendations developed as a result.

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

    Background In the northern hemisphere winter of 2003–04 antigenic variant strains (A/Fujian/411/02 –like) of influenza A H3N2 emerged. Circulation of these strains in the UK was accompanied by an unusually high number of laboratory confirmed influenza associated fatalities in children. This study was carried out to better understand risk factors associated with fatal cases of influenza in children. Methodology/Principal Findings Case histories, autopsy reports and death registration certificates for seventeen fatal cases of laboratory confirmed influenza in children were analyzed. None had a recognized pre-existing risk factor for severe influenza and none had been vaccinated. Three cases had evidence of significant bacterial co-infection. Influenza strains recovered from fatal cases were antigenically similar to those circulating in the community. A comparison of protective antibody titres in age stratified cohort sera taken before and after winter 2003–04 showed that young children had the highest attack rate during this season (21% difference, 95% confidence interval from 0.09 to 0.33, p = 0.0009). Clinical incidences of influenza-like illness (ILI) in young age groups were shown to be highest only in the years when novel antigenic drift variants emerged. Conclusions/Significance This work presents a rare insight into fatal influenza H3N2 in healthy children. It confirms that circulating seasonal influenza A H3N2 strains can cause severe disease and death in children in the apparent absence of associated bacterial infection or predisposing risk factors. This adds to the body of evidence demonstrating the burden of severe illness due to seasonal influenza A in childhood. PMID:19876396

    2014-01-01

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

    The age and sex specific incidence rates, the case fatality rates, and the functional outcome of patients with primary intracerebral haemorrhage occurring in a population of 116,000 during a period of four years four months are presented. A total of 158 patients were identified, the diagnosis was confirmed in 78% by CT, and in 22% by necropsy. The crude annual incidence rate was 31/100,000 population, the age specific rates increased from two to 222/100,000 from the age of 30-39 to over 80 years. Men had higher incidence rates between the ages of 40 and 79 years. The short term case fatality rate was high, 27% of patients dying during the first day after onset of symptoms, and 50% were dead at 30 days. After the first month the probability of survival did not differ from an age- and sex-matched average population. Large haematoma volume had an adverse effect on the short term, old age (greater than 70 years) on the long term survival. Ventricular extension, especially when combined with hydrocephalus was a bad omen for short term survival. Infratentorial and large basal ganglionic haematomas, and primary intraventricular haemorrhage carried a worse prognosis than haematomas of other locations. At the end of a median 32 month follow up 55 (35%) of the patients were alive, 51% of these were independent in activities of daily living, 45% were dependent on outside help, and 4% needed constant nursing care. Old age (greater than 70 years), but not the haematoma volume or location, was associated with a poor functional recovery. PMID:1640229

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

    A few sexual fatalities show ambiguous or conflicting evidence of manner of death or, in cases involving partners, of the partner's intent. In such equivocal cases, postmortem behavioral analysis and reconstruction aid in understanding what happened and provide an explainable basis for expert judgment and opinion, even though some cases can never be resolved with certainty. Behavioral analysis and reconstruction are enhanced by experience with related cases that have been solved, detailed investigation of the death scene and other relevant settings, and interviews with survivors.

    There are few reports concerning Mycobacterium tilburgii infection in humans because this bacterium is non-cultivatable. Herein, using new molecular techniques, we report the case of an immunocompromised patient with fatal disseminated lymphadenitis that was caused by M. tilburgii.26 years old Caucasian HIV negative female patient presented with abdominal pain. Her clinical assessment revealed disseminated lymphadenitis, that was acid fast bacilli positive. Further molecular evaluation showed the causative agent as M. tilburgii. Despite anti mycobacterial therapy and careful management of intervening complications patient died because of an intraabdominal sepsis. This is the first fatal M. tilburgii infection in the literature. This case points the importance of careful management of patient's immune status and intervening infections besides implementation of effective drug treatment.

    Menthol is a monocyclic terpene alcohol, which is present naturally in peppermint and can be synthesized artificially as well. Generally, it is considered as very safe and has wide usage in medicine and food. There are case reports of toxicity due to excessive consumption of menthol, but a fatal intoxication has never been reported in the medical literature. We present a case of fatal menthol intoxication in a worker, who accidently got exposed when he was working in a peppermint factory. Emergency physicians must keep in mind this extremely rare manifestation of menthol poisoning. All necessary precaution should be taken to reduce its intake or exposure, as it has no specific antidote. Early recognition and supportive treatment of this poisoning is the key for a successful outcome. PMID:27127746

    Penile strangulation or entrapment is an unusual entity that requires urgent treatment due to its potential complications. Several cases have been reported in the medical literature, some of them describing serious injuries such as necrosis, gangrene, and amputation of the penis. However, as far as we know, no fatal cases have been described before. We present the death of an adult male secondary to the complications due to penile strangulation with a plastic bottle neck. The time of incarceration was unknown, but according to a witness it could be about 10 to 14 days. The findings of autopsy were penile strangulation, necrosis of the penis, acute pyelonephritis, and bronchopneumonia. The subject's refusal to ask for medical help was the cause of this atypical evolution. PMID:22101437

    Though rare occurrences, fatal falls from bicycles are generally linked to the absence of a protective helmet and/or a collision with another vehicle. The case presented here is exceptional due to its circumstances and the consequences of the accident: a fall with no obstacle at a low speed that brought about multiple traumas and the death of a cyclist wearing a protective helmet. Comparing this against a review of cyclist accidentology literature, this case is unique. The increased use of autopsy in terms of forensic accidentology is to be encouraged so as not to misunderstand the possibility of such lesion-based consequences following a simple fall from a bicycle.

    Neonicotinoid insecticides are considered to be less toxic to humans compared to older insecticides such as organophosphates, carbamates, pyrethroids, and organochlorine compounds. However,reports of severe human toxicity with neonicotinoids are emerging. Acute human thiacloprid poisoning and death as a result have not been reported in the literature so far. Here we report a case of thiacloprid poisoning resulting from deliberate ingestion in a 23-year-old man, manifesting with status epilepticus, respiratory paralysis,rhabdomyolysis, metabolic acidosis, and acute kidney injury (AKI), and ultimately giving rise to refractory shock and death. Thiacloprid can cause fatal human toxicity when ingested heavily, and absence of an effective antidote raises concern in this regard.

  11. Denominator effects on traumatic occupational fatality incidence rates.

    Each year over 6,000 workers are killed while earning a living in the United States. From these deaths, how can researchers determine if employees in the manufacturing industry are at greater risk of a traumatic occupational fatality than those employed in agriculture or any other industry? Similarly, does the risk of traumatic occupational fatality differ among states? To answer such questions, two measurements are normally used: frequency of occurrence and incidence rate. These measures are used to identify worker groups at greatest risk of fatal injury, target research and prevention activities, and evaluate the impact of these activities. Developing the best methods to accurately identify worker groups at greatest risk of losing their life while at work is always important, but even more so in times of limited government resources. The accuracy of a traumatic occupational fatality incidence rate depends on how closely the denominator and numerator represent the same population. Selecting data from different employment programs for the denominator when calculating incidence rates using the National Traumatic Occupational Fatalities surveillance system for the numerator has shown dramatically different results. This analysis points out that researchers must carefully: choose the data they employ; evaluate the meaning of calculated incidence rates; and document the data sources to ensure proper interpretation by others. Additional research and evaluation are necessary to improve data sources, analytical methods and tools to ensure effective resource allocations for the occupational safety and health field.

    Fatal insomnia is a rare human prion disease characterised by sleep-wake disturbances, thalamic degeneration and deposition of type 2 disease-specific prion protein (PrP(Sc)). This report details a patient with sporadic fatal insomnia who exhibited cerebral deposition of type 1 PrP(Sc) and neuropathological changes largely in the basal ganglia. Previous damage of this brain region by a surgically removed colloid cyst and the insertion of two intracerebral shunts may have influenced the distribution of PrP(Sc) through a chronic inflammatory process. These findings add to our knowledge of the phenotypic variability of human prion diseases with prominent sleep disturbances.

    Most propeller injuries occur at water recreational facilities such as those with provision for water skiing, boat racing, skin and scuba diving. Propeller injuries resulting from nautical accidents can be fatal. The sharp blades of propellers rotating at high speeds cause multiple and serious injuries such as deep laceration, chop wounds, bone fractures and mutilation of extremities. We present the autopsy reports of three people who died after colliding with boat propellers.

    Pancytopenia is defined as decrease in red blood cells, white blood cells and platelets. Many disease processes involve the bone marrow primarily or secondarily resulting in pancytopenia. A 55-year-old male presented with generalized body weakness and few episodes of malena for last one year. Physical and systemic examination was unremarkable. CBC report revealed pancytopenia. Other haematological parameters were within normal limit. Stool for occult blood was positive. USG and CECT abdomen showed no abnormality. The patient was evaluated for any evidence of malignancy but no clue was found. Bone marrow examination was done as patient was having pancytopenia. Bone marrow smears, clot sections and bone marrow biopsy was normal. Immunohistochemistry and cytogenetics study was unremarkable. Patient was admitted in hospital for 1 month and his condition rapidly deteriorated. The cause of pancytopenia remained unexplained and therefore it was named as Idiopathic fatal pancytopenia. "Idiopathic Fatal Pancytopenia (IFP)" is an emerging new entity with a grave prognosis. We wish to sensitize the medical community and the scientists to this rapidly fatal condition. PMID:27504300

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

    A death caused by a new designer drug, 4-methylmethcathinone (mephedrone), is reported. Eight small plastic bags containing white powder were found in the jacket of a young dead male. Spot tests conducted by the police officer indicated the presence of 4-bromo-2,5-dimethoxyphenethylamine (2C-B) in the powders. Laboratory routine screening analyses of blood and vitreous humor did not reveal any positive results; therefore, 2C-B was excluded. Analysis of powders was conducted using gas chromatography-mass spectrometry and high-pressure liquid chromatography with diode array detection. The purity of mephedrone found in all powder samples was in the range of 80.4-87.3%. In connection with these findings, blood and vitreous humor samples were analyzed for mephedrone. Analyses were conducted using liquid chromatography-tandem mass spectrometry. Mephedrone was found in blood and vitreous humor at the concentrations of 5.5 and 7.1 µg/mL, respectively, revealing that this was a fatal mephedrone intoxication.

    The frequency of fatalities due to acute bacterial meningitis has decreased significantly due to vaccinations, early diagnoses, and treatments. We studied brain tissues of patients with fatal neutrophilic meningitis referred to the Centers for Disease Control for etiologic diagnosis from 2000-2009 to highlight aspects of the disease that may be preventable or treatable. Demographic, clinical, and laboratory data were extracted from records. Of 117 cases in the database with a diagnosis of meningitis or meningoencephalitis, 39 had neutrophilic inflammation in the meninges. Inflammatory cells infiltrated the superficial cortex in 16 of 39 (41%) cases. Bacteria were found using Gram and bacterial silver stains in 72% of cases, immunohistochemistry in 69% (including two cases where the meningococcus was found outside the meninges), and PCR in 74%. Streptococcus pneumoniae was the cause of the meningitis in 14 patients and Neisseria meningitidis in 9. In addition, Streptococcus spp. were found to be the cause in six cases, while Staphylococcus aureus, Staphylococcus spp., Enterococcus spp., and Fusobacterium were the cause of one case each. There were six cases in which no specific etiological agent could be determined. The mean age of the patients with S. pneumoniae was 39 years (range 0-65), with N. meningitidis was 19 years (range 7-51), whereas that for all others was 31 years (range 0-68). In summary, our study shows that S. pneumoniae continues to be the most frequent cause of fatal neutrophilic bacterial meningitis followed by N. meningitidis, both vaccine preventable diseases.

    The clinical and pathological features of the first two reported cases of herpes simplex encephalitis occurring in Saskatchewan are presented. The clinical history of an acute onset, an early organic mental syndrome followed by coma, neurologic disturbances, rapid progression and death suggests the diagnosis. The acute, diffuse, inflammatory process with predominant involvement of the temporal lobes of the cerebral hemispheres and the presence of intranuclear inclusions in nerve and glial cells are illustrated. The viral particles were found in electron micrographs from the brain tissue of both patients. The definitive diagnosis was established by the isolation, from postmortem brain tissue, of the herpes simplex virus, which was grown in tissue culture and shown to be pathogenic in suckling mice.

    Objectives: Motor vehicle crash fatality rates have been consistently higher in rural areas than in urban areas. However, the explanations for these differences are less clear. In this study the decomposition method was used to explore the factors associated with increased fatal crash involvement rates in rural communities. Design: Using national databases, the fatal crash incidence density was decomposed into the product of three factors: the injury fatality rate, the crash injury rate, and the crash incidence density. Results: As expected, the fatal crash incidence density was more than two times higher in rural than in urban areas. This was driven primarily by the injury fatality rate, which was almost three times higher in rural areas. Conclusions: Further research should examine the relative roles of crash severity and the timely receipt of definitive medical care after a crash. PMID:15691985

    This study used police-reported motor vehicle crash data from eleven states to determine ejection, fatality, and fatal/serious injury risks for belted drivers in vehicles with conventional seatbelts compared to belted drivers in vehicles with seat integrated restraint systems (SIRS). Risks were compared for 11,159 belted drivers involved in single- or multiple-vehicle rollover crashes. Simple driver ejection (partial and complete), fatality, and injury rates were derived, and logistic regression analyses were used to determine relative contribution of factors (including event calendar year, vehicle age, driver age/gender/alcohol use) that significantly influence the likelihood of fatality and fatal/serious injury to belted drivers in rollovers. Results show no statistically significant difference in driver ejection, fatality, or fatal/serious injury rates between vehicles with conventional belts and vehicles with SIRS. PMID:19026243

    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.

    Issues regarding healthcare disparity continue to increase in connection with access to quality care for acute myocardial infarction (AMI), even though the case-fatality rate (CFR) continues to decrease. We explored regional variation in AMI CFRs and examined whether the variation was due to disparities in access to quality medical services for AMI patients. A dataset was constructed from the Korea National Health Insurance Claims Database to conduct a retrospective cohort study of 95,616 patients who were admitted to a hospital in Korea from 2003 to 2007 with AMI. Each patient was followed in the claims database for information about treatment after admission or death. The procedure rate decreased as the region went "down" from Seoul to the county level, whereas the AMI CFR increased as the county level as a function of proximity to the county level (30-day AMI CFRs: Seoul, 16.4%; metropolitan areas, 16.2%, cities; 18.8%, counties, 39.4%). Even after adjusting for covariates, an identical regional variation in the odds of patients receiving treatment services and dying was identified. After adjusting for invasive and medical management variables in addition to earlier covariates, the death risk in the counties remained statistically significantly higher than in Seoul; however, the degree of the difference decreased greatly and the significant differences in metropolitan areas and cities disappeared. Policy interventions are needed to increase access to quality AMI care in county-level local areas because regional differences in the AMI CFR are likely caused by differences in the performance of medical and invasive management among the regions of Korea. Additionally, a public education program to increase the awareness of early symptoms and the necessity of visiting the hospital early should be established as the first priority to improve the outcome of AMI patents, especially in county-level local areas.

    Fatal starvation is a rare cause of death in industrialised countries. In such cases, investigation of death is never an easy task for forensic pathologists who need to couple autopsy findings with full investigation of the crime scene and family record to establish if death results from deliberate neglect, maltreatment and withholding of food. The present article describes two cases of death caused by child neglect. The first case involved a 16-month-old female who died from starvation with dehydration as a contributing factor. In the second case a 7-year-old girl died from ultimate aspiration of stomach contents that had been vomited during the child's last meal because of the fecal concretions blocking the intestinal passage. In both cases macroscopic and histological findings revealed severe chronic malnutrition; crime scene investigations confirmed stories of child maltreatment and neglect. PMID:22391005

    Two people out of three who accidentally ate boiled aconite leaves died in 2012. This was a typical case of aconite poisoning in Japan: Aconite (Aconitum spp.) was mistakenly collected instead of Anemone flaccida, an edible wild plant. The leaves of these plants are quite similar to each other. Chemical analyses of the aconite plant left at the scene suggested intake of a fatal amount of aconitine alkaloids by each person. The collector, who died, had missed the botanical differences between the two plants, even though he owned a wild plant guidebook. A. flaccida should be collected with its flowers in order to aid positive indentification and avoid aconite poisoning.

    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.

    Barium is an alkaline earth metal which has a variety of uses including in the manufacturing industry and in medicine. However, adverse health effects and fatalities occur due to absorption of soluble barium compounds, notably the chloride, nitrate, and hydroxide, which are toxic to humans. Although rare, accidental and suicidal modes of poisoning are sporadically reported in the literature.We describe 4 cases of poisoning due to barium chloride in China. In witnessed cases, severe gastrointestinal symptoms, hypokalemia leading to muscle weakness, cardiac arrhythmias, and respiratory failure were noted. Autopsy showed some nonspecific but common findings, such as subendocardial hemorrhage in the ventricles, visceral petechiae, and fatty changes in the liver. Interestingly, microscopic examination showed degenerative changes and amorphous, flocculent foamy materials in the renal tubules. Toxicology was relevant for barium in blood and tissues. Three of the cases were accidental and 1 homicidal in nature. A round-up of relevant literature on fatal barium compounds poisoning is also provided. Forensic pathologists should be aware of the clinical presentations of barium compound poisoning and especially look for any evidence of hypokalemia. Still, postmortem toxicological and histological studies are essential for an accurate identification of the cause of death.

  14. Fatal case of inhalational anthrax mimicking intra-abdominal sepsis.

    In this report, we discuss the second fatal case of inhalational anthrax related to the use of Bacillus anthracis spores as a biological weapon in the United States. This case highlights two of the major characteristics of inhalational anthrax: the fulminating nature of the infection and the difficulty of promptly establishing a diagnosis. In the patient discussed here, gastrointestinal symptoms and findings were so impressive that the patient was thought to have a primary intra-abdominal condition. In the current situation, in which bioterrorism is a real threat, any patient presenting with a flulike or gastrointestinal illness should be queried about their occupation. Anyone with evidence of systemic disease who resides or works in a geographical region where anthrax cases are occurring should be treated until the diagnosis of anthrax is excluded. In the United States, the group that is at high risk for anthrax has shifted from rural farm workers to city dwellers, especially postal workers and public figures. PMID:12071107

  15. Cardiac beriberi: morphological findings in two fatal cases

    PubMed Central

    2011-01-01

    Cardiovascular beriberi is categorized into two main groups, according to its cause: alcoholic and non-alcoholic (dietary). Cardiovascular beriberi can also be divided into a fulminant form (Shoshin beriberi) and a chronic form. Shoshin beriberi is characterized by hypotension, tachycardia, and lactic acidosis and is mainly encountered in non-alcoholic patients in Asian countries, although it has also been seen in alcoholics in Western countries. Due to the complex clinical presentation and to the lack of diagnostic tests, thiamine deficiency is still being missed, especially among non-alcoholics patients. We present two fatal cases of non - alcohol associated cardiac beriberi. An acute myocardial infarction was observed in one case; extensive colliquative myocytolisis (grade 2) was described in the second case respectively. Morphologically, myocardial necrosis and colliquative myocytolysis are the histologic hallmarks of this acute, rare clinical entity. An increase in apoptotic myocytes was demonstrated probably sustaining the cardiogenic shock. PMID:21244717

    Blank firing pistols are generally considered to be harmless and these guns are not accepted as being firearms in most countries. Due to lack of legal regulations these guns are easily purchased by anyone aged over 18 years. Reports of serious injuries and even fatalities due to these guns are increasing in the literature. These guns when modified or even unmodified can cause serious and potentially fatal injuries. Without doing any changes to the barrel, using blank or tear gas cartridges, firing at contact range can cause penetration of gas into the body including bone originated from gun powder. We report two suicide cases shooting themselves at temporal region with a blank cartridge gun at contact range. There was no foreign body on radiological examination and there was no trajectory of a bullet inside the brain. In both cases the wound was at the right temporal region and there was defect at temporal bone. There was circular soot around this bone defect. The injury of the brain tissue was localized at the level of the defect but there was widespread subarachnoidal bleeding. We discussed the potential danger of these guns and stressed the need of legal regulations concerning these guns.

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

    A number of states in the United States have laws restricting drivers from using cellphones. Using state-level panel data, we examined the effect of cellphone laws on fatal crashes in the United States between 2000 and 2010. Our results show that there is insufficient power to detect a reduction in overall fatal crash rates scaled by vehicle miles and population estimates. Cellphone bans, however, have significantly reduced the fatal crash rates of drivers in certain age cohorts. The effect was most pronounced among drivers between 18 and 34 years of age. We did not find any significant effect among drivers in the 55 and older age cohorts.

    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.

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

    Erysipelas is a generally benign superficial bacterial skin infection, and its bullous form constitutes a rare and more severe variant. We describe the first and fatal case of "bullous erysipelas-like" septic vasculitis due to Pseudomonas bacteremi. A 69-year-old Chinese man presenting with diarrhea and septic shock initially began to rapidly develop sharply defined erythematous plaques with non-hemorrhagic bullae over his lower limbs. Culture of the aspirate from the bullae was positive for Pseudomonas aeruginosa. This was also consistent with his blood cultures showing Pseudomonas bacteremia. Histology of the skin lesion showed microthrombi and neutrophilic infiltrates in blood vessels with Gram-negative bacilli extruding from the vessel walls, characteristic of septic vasculitis. The bullous erysipelas-like lesions seen in this patient represents a rare manifestation of both septic vasculitis and Pseudomonas infection. PMID:26955132

    Pancreatic panniculitis is a rare disease in which necrosis of fat in the panniculus and other distant foci occurs in the setting of pancreatic diseases; these diseases include acute and chronic pancreatitis, pancreatic carcinoma, pseudocyst, and other pancreatic diseases. This malady is manifested as tender erythematous nodules on the legs, buttock, or trunk. Histopathologically, it shows the pathognomonic findings of focal subcutaneous fat necrosis and ghost-like anucleated cells with a thick shadowy wall. We herein report a case of fatal pancreatic panniculitis that was associated with acute pancreatitis in a 50-yr-old man. He presented with a 3-week history of multiple tender skin nodules, abdominal pain and distension. Laboratory and radiologic findings revealed acute pancreatitis, and skin biopsy showed pancreatic panniculitis. Despite intensive medical care, he died of multi-organ failure 3 weeks after presentation. PMID:17982246

    Objectives. We investigated the extent to which the political economy of US states, including the relative power of organized labor, predicts rates of fatal occupational injury. Methods. We described states’ political economies with 6 contextual variables measuring social and political conditions: “right-to-work” laws, union membership density, labor grievance rates, state government debt, unemployment rates, and social wage payments. We obtained data on fatal occupational injuries from the National Traumatic Occupational Fatality surveillance system and population data from the US national census. We used Poisson regression methods to analyze relationships for the years 1980 and 1995. Results. States differed notably with respect to political–economic characteristics and occupational fatality rates, although these characteristics were more homogeneous within rather than between regions. Industry and workforce composition contributed significantly to differences in state injury rates, but political–economic characteristics of states were also significantly associated with injury rates, after adjustment accounting for those factors. Conclusions. Higher rates of fatal occupational injury were associated with a state policy climate favoring business over labor, with distinct regional clustering of such state policies in the South and Northeast.

    Epidemiological and medicolegal, including forensic pathological, aspects of 180 cases of fatal burns were studied in Kanpur (India) during the period of one year (October 1985 to September 1986). These constituted 10.79% of the total medicolegal deaths autopsied. Majority of the victims were young Hindu housewives burnt within 5 years of their marriage. The most common source of fire was cooking apparatus like chulha, coalfire, stove or cooking gas. In a substantial number of cases, kerosene oil was poured over the victims and fired with a match stick. About half of the burn cases were accidental, in which cooking on open unguarded flames and loose highly inflammable synthetic sarees of the victims can be blamed. Among the others who died in suspicious circumstances, i.e., burnt alive or forced to commit suicide by fire, dowry and family quarrels and marital disharmony were the two important predisposing factors. Illiteracy, arranged and child marriages, joint family structure, oedipal dominance of mother-in-laws, unemployment and economic dependence of the husband on the parents, near complete dependence of women on their husbands and inlaws, and lack of social security amongst Hindu females were other contributory factors affecting the incidence in some way. Male burn deaths were few and usually accidental.

    The study aimed to describe severe and fatal cases of box jellyfish stings in Thailand. Medical records were reviewed and patients, relatives, health staffs, and witnesses were interviewed. The pictures of suspected box jellyfish were sent via e-mail to experts in the toxic jellyfish network for further identification. There were at least 8 cases of box jellyfish envenomation, with 4 fatal and 4 near-fatal cases. There were an equal number of male and female patients from 4 to 26 years of age. In each case, there was immediate severe pain followed by systemic reactions. Immediately after exposure to the sting, 7 victims collapsed experiencing severe pain at the tentacle marks, respiratory failure, and cardiac arrest. All patients had tentacle marks on their bodies. In none of the fatal cases was vinegar applied to the tentacle marks as first aid, but 3 out of the 4 near-fatal cases were treated with a vinegar application. PMID:22743852

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

    Myroides spp., previously known as Flavobacterium odoratum, are rare clinical isolates and are often considered non-pathogenic. Natural habitat includes soil, fresh and marine waters, in foods and in sewage treatment plants. We present an unusual case of fatal pericardial effusion due to Myroides odoratus in a patient suffering from chronic kidney disease and undergoing maintenance haemodialysis. This case is presented to show the increasing incidence of rare isolates causing localized and systemic infections and due to their high intrinsic resistance to many antibiotics they can be fatal. Thus isolation of these pathogens is of great clinical importance. PMID:26672889

His classmates reported that they had been playing, and throwing building bricks, when suddenly the boy collapsed. The emergency physician did not find significant injuries. Upon admission to a hospital, CT imaging revealed a "blood path" through the brain. After clinical forensic examination, an impalement injury was diagnosed, with the entry wound just below the left eyebrow. Eventually, the police presented a variety of pointers that were suspected to have caused the injury. Forensic trace analysis revealed human blood on one of the pointers, and subsequent STR analysis linked the blood to the injured boy. Confronted with the results of the forensic examination, the classmates admitted that they had been playing "sword fights" using the pointers, and that the boy had been hit during the game. The case illustrates the difficulties of diagnosing impalement injuries, and identifying the exact cause of the injury. PMID:27555425

    The use of quetiapine in Australia has increased rapidly in recent years. Anecdotal and post-marketing surveillance reports indicate an increase in quetiapine misuse in prisons as well as an increase in its availability on the black-market. This study examined a cohort of quetiapine-associated deaths occurring in Victoria, Australia, between 2001 and 2009, to determine the prevalence of deaths associated with this drug and to determine whether misuse represents a legitimate concern. Case details were extracted from the National Coronial Information System. There were 224 cases with an average age of 43 years of age (range 15-87 years). The cause of death was mostly drug toxicity (n = 114, 51 %), followed by natural disease (n = 60, 27 %), external injury (n = 31, 14 %) and unascertained causes (n = 19, 8 %). Depression and/or anxiety were common, observed in over a third of the cohort (80 cases, 36 %). About 20 % of cases did not mention a psychiatric diagnosis at all which raises the question of whether quetiapine had been prescribed correctly in these cases. Cardiovascular disease was the most commonly reported illness after mental disease. Quetiapine ranged in concentration from the limit of reporting (0.01 mg/L) to 110 mg/L. The median concentration of quetiapine was much lower in the natural disease deaths (0.25 mg/L) compared with drug caused deaths (0.7 mg/L). The most commonly co-administered drug was diazepam in 81 (36 %) cases. There were a small number of cases where quetiapine contributed to a death where it had not apparently been prescribed, including the death of a 15 year old boy and one of a 34 year old female. Overall, misuse of quetiapine did not appear to be a significant issue in this cohort; use of the drug only occasionally led to fatalities when used in excess or concomitantly with interacting drugs. However, considering that it is a recent social concern, it is possible that analysis of cases post 2009 would reveal

    It is reasonable to expect the presence of multiple drugs to present a complicated picture of toxicity. We report a fatal case involving a young man who purchased illicit drugs and knowingly consumed them. After consuming these drugs and going to sleep in his friend's car, he was found unresponsive the next morning with no signs of physical violence. Drugs found in the peripheral blood at autopsy were oxymorphone, methylone and ethanol at concentrations of 0.106, 0.50 and 130 mg/dL, respectively. The levels of oxymorphone and methylone in peripheral blood were comparable to those observed in other reported fatalities. Cocaine and benzoylecgonine were detected in the urine but not in the blood. Measureable concentrations were also observed for oxymorphone and methylone in urine, liver, kidney and bile. The physical findings at autopsy included pulmonary edema. This is the only reported fatal case involving this combination of drugs encountered in our laboratory. PMID:27405363

    Healthy human heart rate is known to fluctuate in a highly complex manner, displaying complexity characteristics such as those shared by physical systems at a critical state. It is, however, widely believed that chronic heart failure reduces this complexity and that heart rate data from chronic-heart-failure patients can be used for the validation of complexity measures and paradigms applicable both to heart rate and more generally to assess any system's complexity. Here, we counter the above belief, showing an increase in fluctuations and in complexity of heart rate in chronic-heart-failure patients, in particular those at risk of death. This is supported by evidence of increased non-Gaussianity and heteroscedasticity resulting from the emergence of a characteristic correlation scale in the magnitude correlation landscape.

    Tapentadol (TAP) is an analgesic agent indicated for the management of different types of pain. It has a novel mechanism of action in that it induces analgesia via both μ-opioid receptor agonism and norepinephrine reuptake inhibition. Although deaths associated with TAP use have been reported, there is a paucity of published literature regarding TAP concentrations in biological samples obtained from TAP-associated fatalities. We report a case of TAP toxicity resulting in death with postmortem peripheral and central blood concentrations, liver, vitreous, urine, and gastric contents. A 41-year-old female was found slumped over a sink at home following a welfare check by police. She was transported to a local hospital where she was pronounced dead despite all resuscitative measures. The autopsy was remarkable only for pulmonary edema and signs of aspiration pneumonia. Postmortem concentrations of TAP were confirmed in peripheral blood at 1.1mg/L, central blood 1.3mg/L, liver 9.9mg/kg, vitreous humor 0.94mg/L, urine 88mg/L, and the gastric contained 2mg. Also of note, oxycodone was found in the decedent's blood at a concentration of 0.58mg/L. We report a death related to an intentional ingestion of TAP and oxycodone-the cause and manner of death were determined to be mixed drug intoxication; suicide. We hope that the variety of TAP concentrations identified in this case provide valuable points of reference for future cases of TAP intoxication. PMID:27568082

    We describe a first fatal case of repellent air freshener ingestion. A 79-year-old Japanese man with Alzheimer-type senile dementia orally ingested repellent air freshener containing three surfactants: polyoxyethylene 9-lauryl ether, polyoxyethylene (40) hydrogenated castor oil, and lauric acid amidopropyl amine oxide (weight ratio of 1.3%). About 1h after the collapse, he was in cardiopulmonary arrest and subsequently died 10h after his arrival. The forensic autopsy performed 5.5h after death revealed the 380ml of stomach contents with a strong mint perfume identical to that of the repellent air freshener and the findings of acute death. Toxicologically, 9.1μg/ml and 558.2μg/ml of polyoxyethylene 9-lauryl ether were detected from the serum and stomach contents taken at autopsy. Generally, ingestion of anionic or non-ionic surfactants have been considered as safe. However, because the patient suffered from cardiac insufficiency with a low dose of repellent air freshener ingestion, medical staff members must evaluate the elderly patient for cardiac and circulatory problems regardless of the ingested dose. Not only medical and nursing staff members, but also families who are obliged to care for elderly persons must be vigilant to prevent accidental ingestion of toxic substances generally used in the household.

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

    We describe a first fatal case of repellent air freshener ingestion. A 79-year-old Japanese man with Alzheimer-type senile dementia orally ingested repellent air freshener containing three surfactants: polyoxyethylene 9-lauryl ether, polyoxyethylene (40) hydrogenated castor oil, and lauric acid amidopropyl amine oxide (weight ratio of 1.3%). About 1h after the collapse, he was in cardiopulmonary arrest and subsequently died 10h after his arrival. The forensic autopsy performed 5.5h after death revealed the 380ml of stomach contents with a strong mint perfume identical to that of the repellent air freshener and the findings of acute death. Toxicologically, 9.1μg/ml and 558.2μg/ml of polyoxyethylene 9-lauryl ether were detected from the serum and stomach contents taken at autopsy. Generally, ingestion of anionic or non-ionic surfactants have been considered as safe. However, because the patient suffered from cardiac insufficiency with a low dose of repellent air freshener ingestion, medical staff members must evaluate the elderly patient for cardiac and circulatory problems regardless of the ingested dose. Not only medical and nursing staff members, but also families who are obliged to care for elderly persons must be vigilant to prevent accidental ingestion of toxic substances generally used in the household.

    Two case studies are presented involving fatal falls of adult females from a height. One involved a launch at low speed from a balcony, and one involved a launch at high speed from the top of a cliff. Crime scene evidence obtained on the balcony itself provided a strong indication of homicide, but subsequent investigation showed that the fall was accidental. No crime scene evidence was obtained for the cliff fall since the fall initially appeared to be just another suicide from a popular suicide spot. Subsequent investigations indicated homicide based on measurements of cliff height, horizontal distance to the impact, and available runup distance, plus measurements of possible run, jump, and throw speeds. It was found that a female weighing 61 kg (134 lb) can be thrown at speeds up to 4.85 m/s by a strong male, more than enough to account for the estimated launch speed (4.5 m/s). Given the available 4.0 m runup distance, it was found that women of better than average rather than elite athletic ability can dive at speeds of about 3.5 m/s or jump feet first at speeds of about 4.0 m/s, both being less than the estimated launch speed. The decedent had no athletic ability and landed head first after falling through a height of 29 m. PMID:16423230

    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.

    Between 1994 and 2009, the Dr Gustavo Aldereguía University Hospital of Cienfuegos, Cuba implemented a series of interventions that reduced acute myocardial infarction case fatality rate from 47% to 15%. These interventions were part of an institutional plan for myocardial infarction included in the hospital's overall quality assurance strategy. Outcomes resulted primarily from organizational changes (from upgrading of the hospital emergency department and provincial emergency system to creation of a comprehensive coronary care unit and a chest pain center); optimizing use of effective drugs (streptokinase, aspirin, ACE inhibitors and beta blockers); adherence to clinical practice guidelines; and continual and participatory evaluation and adjustment.

    2014-01-01

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

    Background The aim of this study was to explore temporal trends in incidence and case fatality rates of intracerebral hemorrhage (ICH) over the last two decades in a Norwegian municipality. Methods Incident cases of primary ICH were registered in the period from 1995 through 2012 in 32,530 participants of the longitudinal population-based Tromsø Study. Poisson regression models were used to obtain incidence rates over time in age- and sex-adjusted and age- and sex-specific models. Case fatality rates were calculated and age- and sex-adjusted trends over time were estimated using logistic regression. Results A total of 226 ICHs were registered. The age- and sex-adjusted incidence rate [95% confidence interval (CI)] in the overall population was 0.42 (0.37-0.48) per 1,000 person-years. Age-adjusted incidence rates were 0.53 (0.43-0.62) in men and 0.33 (0.26-0.39) in women. In individuals aged <75 years, the age- and sex-adjusted incidence rate was 0.27 (0.22-0.32) and in individuals aged ≥75 years, it was 2.42 (1.95-2.89) per 1,000 person-years. There was no significant change in incidence rates over time. The incidence rate ratio (95% CI) in the overall population was 0.73 (0.47-1.12) in 2012 compared with 1995. The overall 30-day case fatality (95% CI) was 23.9% (18.3-29.5) and did not change substantially over time [odds ratio in 2012 vs. 1995 = 0.83 (95% CI 0.27-2.52)]. Conclusion No significant changes in incidence and case fatality rates of ICH were observed during the last two decades. PMID:27522404

    Case fatality rate is considered a main determinant of stroke mortality trends. We applied the World Health Organization's Stroke STEPS to identify case fatality rates in a community hospital in Brazil. We evaluated all patients with first-ever stroke seeking acute care at the hospital's emergency ward between April 2006 and December 2008 to verify early and late case fatality according to stroke subtype. We used years of formal education as a surrogate for socioeconomic status. Of 430 first-ever stroke events, 365 (84.9%) were ischemic and 65 (15.1%) were intracerebral hemorrhage. After 1 year, we adjudicated 108 deaths (86 ischemic; 22 hemorrhagic). Age-adjusted case fatality rates for ischemic stroke and intracerebral hemorrhage were 6.0% v 19.8% at 10 days, 10.6% v 22.1% at 28 days, 17.6% v 29.1% at 6 months, and 21.0% v 31.5% at 1 year. Illiteracy or no formal education was a predictor of death at 6 months (odds ratio [OR], 4.31; 95% confidence interval [CI] 1.34-13.91) and 1 year (OR, 4.21; 95% CI, 1.45-12.28) in patients with ischemic stroke, as well as at 6 months (OR, 3.19; 95% CI, 1.17-8.70) and 1 year (OR, 3.30; 95% CI, 1.30-8.45) for all stroke patients. Other variables, including previous cardiovascular risk factors and acute medical care, did not change this association to a statistically significant degree. In conclusion, case fatality, particularly up to 6 months, was higher in hemorrhagic stroke, and lack of formal education was associated with increased stroke mortality.

    The aim of this study was to assess the relationship between the ratification status of occupational safety and health (OSH)-related ILO conventions and reported occupational fatality rates of ILO member countries, while controlling for possible confounding factors. ILO member states were divided into 4 levels of income status, based on the gross national income per capita. Seventeen conventions designated as OSH-related were examined. Reported country occupational fatality rates were compared according to the ratification status of these 17 conventions and multiple regression analyses were conducted to assess the relationship between the fatality rates, ratification status, income level and length of ILO membership. Fatality rates were inversely and significantly related to income levels. In general, non-ratifying countries had higher work-related fatality rates than ratifying countries. A statistical model for identifying predictors of fatal injury rates showed that a larger number of conventions ratified was significantly associated with lower fatality rates. The fact that non-ratifying countries generally have higher fatality rates than ratifying ones supports the notion that all countries should promote ratification of ILO conventions aimed at improving OSH conditions.

    Dengue virus can infect many cell types from the vascular, muscular and hematological systems causing diverse clinical and pathological signs. The purpose of the present study was to investigate by different diagnostic methods dengue virus in human tissue specimens obtained from fatal cases (n=29) during a large-scale dengue fever epidemic in 2002 in the State of Rio de Janeiro, Brazil. The combination of four procedures provided diagnostic confirmation of DENV-3 infection in 26 (89.6%) out of the 29 suspected fatal cases. Dengue virus (DENV) was isolated from 2/74 (2.7%) tissue samples, inoculated into C6/36 cells and identified as DENV-3, nested RT-PCR accusing 22/72 (30.5%) samples as DENV-3. Real-time RT-PCR yielded the highest positivity rate, detecting viral RNA in 45/77 (58.4%) clinical specimens, including the liver (n=18), lung (n=8), spleen (n=8), brain (n=6), kidney (n=3), bone marrow (n=1) and heart (n=1). Immunohistochemical tests recognized the DENV antigen in 26/59 (44%) specimens. Given the accuracy and effectiveness of real-time RT-PCR in this investigation, this approach may play an important role for rapid diagnosis of dengue infections.

    Diethylene glycol is a common industrial solvent which is responsible for accidental and epidemic poisoning as early as the 1930s. Due to the unavailability and unaffordability of ethanol, people in Qatar among the low income group are consuming household chemicals, some of which contain diethylene glycol, for recreational purposes.The history of ingestion is usually not volunteered and the initial clinical presentation is usually nonspecific, making it difficult to diagnose from the clinical presentation. Moreover, the biochemical profile varies with time, making the diagnosis more difficult. The neurological course and toxicity is less well characterized than its renal counterpart. Moreover, reports in the literature of such recreational poisoning is lacking particularly in the region.Three cases of recreational diethylene glycol poisoning seen in Hamad General Hospital, Doha, Qatar from 2009 to 2012 are detailed here.These illustrate the clinical course with emphasis on the neurological sequelae that include encephalopathy and multiple cranial and peripheral neuropathies with fatal and near-fatal outcomes. Neuroimaging in 2 were initially normal, but follow-up imaging showed brain atrophy. The third patient's neuroimaging showed diffuse brain edema with evidence of transtentorial herniation. Nerve conduction studies were performed in 2 of the 3 cases and showed evidence of mixed sensorimotor neuropathy. The outcomes were death in 1 and severe neurological morbidity and disability in 2 cases.Diethylene glycol is a dangerous substance when ingested and can result in mortality and severe morbidity, particularly from the renal and neurological manifestations. Whereas the mechanism of damage is less well known, the damage is likely dose related. The typical clinical pattern of evolution of the poisoning in the absence of cost-effective ways to detect it in the serum can help clinicians in making the diagnosis.Neurological manifestations may include encephalopathy and

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

    A 13-year-old boy, born prematurely and hypotonic, from non-consanguineous healthy parents, was referred to our department because of easy bruising. A slightly extensible, thin and translucent skin, associated with dysmorphic facies, acrogeria, multiple ecchymoses, hypermobility of the small joints, dorsal kyphosis, genu valgum, flat feet, elongated upper limbs, and low muscle tone were all evident. A history of learning disability and bilateral inguinal hernia was present. Blood and imaging studies were unremarkable. A skin biopsy disclosed an unremarkable dermis; electron microscopy showed abnormalities in the diameter, contour, and shape of collagen fibrils/fibers. Genetic analysis revealed heterozygosity for a novel mutation in COL3A1 gene (c.3527G>A), confirming the diagnosis of vascular Ehlers-Danlos syndrome (VEDS). The patient died at 15 years of age because of aortic dissection. Vascular Ehlers-Danlos syndrome is a rare, life-threatening, autosomal dominant variant of EDS, resulting from mutations in COL3A1 gene. Affected individuals are prone to serious and potentially fatal complications, especially vascular, intestinal, and uterine ruptures. Delay in diagnosis is common, even when the clinical presentation is typical. Therefore, dermatologists should be familiar with VEDS features because the skin findings may be the first signs. Early diagnosis will improve management of visceral complications and allow early genetic counseling. PMID:21549076

    Gabapentin (GBP) (Neurontin®, Horizant®, Gralise®) is a widely prescribed medication used primarily for the treatment of epilepsy and neuropathic pain. GBP has a favorable adverse effect profile in therapeutic dosing with the most common reported effects being dizziness, fatigue, drowsiness, weight gain, and peripheral edema. Even with intentional GBP self-poisonings, serious effects are rare. A 47-year-old female was found dead at work with her daughter's bottle of GBP 600 mg. There were 26 tablets missing and the decedent's only known medication was hydrocodone/acetaminophen. Following initial detection by an alkaline drug screen (GC-MS), analysis utilizing specific liquid chromatography-mass spectrometry revealed an elevated postmortem GBP peripheral blood concentration of 37 mg/L, central blood 32 mg/L, liver 26 mg/kg, vitreous 32 mg/L, and gastric contents 6 mg. Screening for volatiles, drugs of abuse, alkaline compounds, and acid/neutral compounds was negative with the exception of ibuprofen (<2 mg/L) detected in peripheral blood. This report presents a fatality that appears to be associated with an isolated and acute GBP ingestion. PMID:25904080

We report the case of a 5 year-old boy with epilepsy treated with VPA 40 mg/kg/day associated with CBZ 20 mg/kg/day and PB 3 mg/kg/day, admitted for vomiting, abdominal pain, low grade fever, abdominal tension and amylasis of 288 UI. On evolution presented upper digestive hemorrhage, shock and amylasis of 564 UI. The patient was submitted to exploratory laparotomy with findings of hemorrhagic ascitis, retroperitoneal hematoma, increased volume of pancreas with edema and hemorrhage leading to diagnosis of necro-hemorrhagic pancreatitis and a fatal course. Pancreatic complications are well known complications related to VPA treatment and may vary between asymptomatic hyperamilasemy to fatal acute pancreatitis. The characteristics of our patient correlates with the data on literature: we found 7 similar cases reported, 4 of which died.

    Complications due to infection by aspergillus and favorized by therapeutic immunodepression are a significant cause of mortality after cardiac transplantation, but are only rarely diagnosed before autopsy. A detailed description of the anatomical lesions and their localisation might help the interpretation of symptoms observed in vivo. In a series of 147 autopsies subsequent to cardiac transplantation, aspergillosis appeared as the cause of death in 26 cases. Three anatomoclinical presentations could be identified: early post-operative septic pyohaemia (14 cases), delayed septic pyohemia (7 cases) and forms with predominantly pulmonary involvement (5 cases). In the first category, cardiac lesions are the most evident with myocardial micro-abscesses and intracardiac masses of aspergillus presenting a variable risk of embolism. Pulmonary < target lésions > (infarctus associated with a variable degree of aspergillus arterial thrombosis) were present in all cases. Visceral involvement completes the picture; the more frequent lesions being acute pancreatitis (9 cases), infarctogenic aspergillus emboli of the kidneys (11 cases), the spleen (9 cases) or the brain (6 cases). In 8 subjects, microscopical examination revealed other germs associated with aspergillus. The serious consequences of aspergillus infection after cardiac transplantation imply that every preventive precaution should be taken, especially in avoiding possible contamination of the air of the operating room by the installation of filters and the regular control of airways and air conditioning systems.

    Spectacular cases of healing of usually fatal diseases gain much attention and put pressure on physicians to apply treatments which have not been sufficiently approved in clinical studies. But often these cases are poorly documented. Also, the number of spontaneous remissions in cancer is greatly overestimated. Promising individual observations must be confirmed by case series in order to collect information which can help future patients. Efforts are necessary to organize well planned studies, especially on rare diseases.

The patient was a 55-year-old female undergoing surgery for severe rheumatic mitral valve disease. Factors responsible for this catastrophic incident are the anticoagulation of the patient, the edematous state of the soft tissues, and the multiple punctures of the wall of the jugular vein.

    Hepatic portal venous gas is a rare cause of acute abdomen caused by leakage of air from the gastrointestinal tract to the portal venous system. The mortality is high, particularly when associated with intestinal ischemia or necrosis. We describe a fatal case of hepatic portal venous gas and pneumatosis intestinalis due to hemodialysis-related hypotension and severe atherosclerotic disease. PMID:27800516

    We report a fatal case of acute chest syndrome in an African-American male. The patient was hospitalized for respiratory distress, fevers, and pulmonary infiltrates after working in an attic space on a summer day. An extensive work-up failed to reveal an etiology for his respiratory failure. He died of respiratory failure two weeks after admission. Autopsy findings suggested the patient had clinically unrecognized sickle cell trait exacerbated by working in the heat, causing acute chest syndrome with a fatal outcome. Clinicians should consider acute chest syndrome and sickle cell trait in the differential diagnosis of patients with unexplained respiratory failure and pulmonary infiltrates. PMID:22679680

    We present a surprising case of suicide by self-immolation. A surveillance camera filmed the victim's agony. We were able to ascertain that he survived 13 min after ignition. This case was the starting point for a review of the literature of the forensic elements required to correctly analyze cases of suicide by self-immolation and to establish the causal link between the burn lesions and death. The authors will focus on the forensic and medical aspects in favor of suicide by self-immolation and on the forensic aspects required to understand the ignition process, the circumstances surrounding the fire with a particular emphasis on determining whether an accelerant was doused on the victim before ignition.

    Serotonin syndrome is a potentially life-threatening reaction that occurs in patients using drugs that elevate the serotonin level in the body. Excess serotonergic activity in the CNS and peripheral serotonin receptors results in neuromuscular hyperactivity, mental changes and autonomic symptoms. Hyperthermia is a characteristic feature of the syndrome. We describe neuropathological findings from two cases of lethal serotonin syndrome, both patients presenting with hyperthermia and neuromuscular symptoms. One of the patients had been taking amitriptylin and mirtazapin and the other had used amitriptylin and citalopram. They died, respectively, 10 days and 2½ months after the onset of serotonin syndrome symptoms. Post-mortem examination of the brains showed subtotal loss of cerebellar Purkinje cells in both cases. In the case with shorter survival time, areas with partial loss of cerebellar granule cells were observed, whereas in the case with longer survival time general and extensive loss of granule cells was found. Cells in other areas of the brain known to be sensitive to hypoxic injury were not affected. Selective loss of Purkinje cells has previously been described in neuroleptic malignant syndrome and heatstroke, conditions that are characterized by hyperthermia. This suggests that hyperthermia may be a causative factor of brain damage in serotonin syndrome. This is the first report describing neuropathological findings in serotonin syndrome.

    Community-associated infections and especially pleural empyema due to Staphylococcus aureus are increasing worldwide. The virulence of staphylococcal strains is notably determined by different toxin expressing-genes, such as the Panton-Valentine leukocidin (PVL) gene found in S. aureus isolates obtained from pediatric necrotizing pneumonia samples. We describe 2 similar cases of infants with severe respiratory distress and death after an upper respiratory tract infection, having occurred in the same urban area during the same winter time. Necropsies performed between November 2006 and March 2007 revealed bronchopneumonia and an important pleural empyema, justifying the review of clinical charts and laboratory exams. A methicillin-sensitive S. aureus (MSSA) isolate carrying the PVL gene was identified in both cases. We have subsequently cared for an additional case in the same time interval with sudden death and similar pathological findings. No positive microbiological results were obtained, a negative finding possibly related to a 5-day antibiotics regimen. This report describes the pathological features of these cases and stresses the need to recognize PVL-positive S. aureus infections in young children. Finally, we believe that all lethal infections due to PVL-positive S. aureus, independently of the methicillin resistance profile, deserve a mandatory report to the provincial public health authorities.

    Drugged driving is a serious safety concern, but its role in motor vehicle crashes has not been adequately studied. Using a case-control design, the authors assessed the association between drug use and fatal crash risk. Cases (n=737) were drivers who were involved in fatal motor vehicle crashes in the continental United States during specific time periods in 2007, and controls (n=7719) were participants of the 2007 National Roadside Survey of Alcohol and Drug Use by Drivers. Overall, 31.9% of the cases and 13.7% of the controls tested positive for at least one non-alcohol drug. The estimated odds ratios of fatal crash involvement associated with specific drug categories were 1.83 [95% confidence interval (CI): 1.39, 2.39] for marijuana, 3.03 (95% CI: 2.00, 4.48) for narcotics, 3.57 (95% CI: 2.63, 4.76) for stimulants, and 4.83 (95% CI: 3.18, 7.21) for depressants. Drivers who tested positive for both alcohol and drugs were at substantially heightened risk relative to those using neither alcohol nor drugs (Odds Ratio=23.24; 95% CI: 17.79, 30.28). These results indicate that drug use is associated with a significantly increased risk of fatal crash involvement, particularly when used in combination with alcohol. PMID:24076302

    2010-01-01

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

She presented nine days after the onset of acute periumbilical abdominal pain which was later accompanied three days prior to admission by purulent discharge from the umbilicus. Radiological investigation revealed a pelvic collection of pus with retroperitoneal extensions. Late presentation made the attempt to save the patient unsuccessful. A review of the literature reveals that extensive intraperitoneal and retroperitoneal extension of abscess resulting from anomaly of the urachus is extremely rare.

    Legionnaire's disease (LD) has been responsible for the death of many patients in several outbreaks in the United States and abroad. The Legionnaire's bacterium is still unclassified. Deoxyribonucleic acid studies of its genes have not yet found a near relative. A case of a 63-year-old man who had a total larynegectomy for cancer of the larynx is reported. He had an extensive postoperative pneumonia, secondary to LD. The diagnosis was made while the patient was alive, but he died on the 35th hospital day in spite of erythromycin treatment.

    A 72-year-old woman with a history of type 2 diabetes mellitus was brought to the ER with metformin-associated lactic acidosis. She received continuous hemofiltration and hemodialysis, but the laboratory analyses showed no improvement. She died 11 hours after admission. Metformin is minimally bound to proteins and is readily dialyzable, but a prolonged period of dialysis is required, because metformin has a very large distribution volume and is distributed to multiple compartments. The peak blood metformin level was 432 mg/L in this case, which is one of the highest metformin concentrations ever reported, and eight hours of hemodialysis were not sufficient to reduce the serum level.

    Purpose: To describe a case of toxic epidermal necrolysis likely caused by cephalexin with a review of the literature. Case: An 80-year-old male with a known allergy to cephalosporins, residing at a long-term acute care hospital, received cephalexin for a urinary tract infection. And 1 day after starting therapy, the patient developed an extensive erythematous rash accompanied by skin sloughing; 4 days after receiving cephalexin, the patient was directly admitted to the burn intensive care unit and was diagnosed with toxic epidermal necrolysis involving 56% of the total body surface area. Progressive deterioration to multisystem organ failure ensued, and the patient died 5 days following his admission to the burn intensive care unit. At the time of death, ulcerations were noted over approximately 80% of his body. Summary: The temporal association of the patient’s ingestion of cephalexin for a urinary tract infection to his onset of toxic epidermal necrolysis suggests that this 80-year-old man developed toxic epidermal necrolysis following the administration of cephalexin for a urinary tract infection.

    ABSTRACT Blunt cerebrovascular injury (BCVI) is usually caused by neck trauma that predominantly occurs in high-impact injuries. BCVI may occur due to damage to both the vertebral and carotid arteries, and may be fatal in the absence of appropriate treatment and early diagnosis. Here, we describe a case of cerebral infarction caused by a combination of a lower cervical spinal fracture and traumatic injury to the carotid artery by a direct blunt external force in a 52-year-old man. Initially, there was no effect on consciousness, but 6 hours later loss of consciousness occurred due to traumatic dissection of the carotid artery that resulted in a cerebral infarction. Brain edema was so extensive that decompression by emergency craniectomy and internal decompression were performed by a neurosurgeon, but with no effect, and the patient died on day 7. This is a rare case of cerebral infarction caused by a combination of a lower cervical spinal fracture and traumatic injury to the carotid artery. The case suggests that cervical vascular injury should be considered in a patient with a blunt neck trauma and that additional imaging should be performed. PMID:26412898

    A 24-year-old man whose medical history was significant for alcohol abuse and depression was found unresponsive in bed. He had several prior suicide attempts with 'pills' and had also been hospitalized for an accidental overdose on a previous occasion. Autopsy findings were unremarkable apart from pulmonary edema and congestion, and urinary retention. Postmortem peripheral blood initially screened positive for mitragynine 'Kratom' (by routine alkaline drug screen by gas chromatography-mass spectrometry, GC-MS), which was subsequently confirmed by a specific GC-MS selective ion mode analysis following solid-phase extraction. Concentrations were determined in the peripheral blood (0.23 mg/L), central blood (0.19 mg/L), liver (0.43 mg/kg), vitreous (<0.05 mg/L), urine (0.37 mg/L) and was not detected in the gastric. Therapeutic concentrations of venlafaxine, diphenhydramine and mirtazapine were also detected together with a negligible ethanol of 0.02% (w/v). The results are discussed in relation to previous cases of toxicity, and the lack of potential for mitragynine postmortem redistribution. PMID:25516573

    Cerebral air embolism (CAE) is an infrequently reported complication of routine medical procedures. We present two cases of CAE. The first patient was a 55-year-old male presenting with vomiting and loss of consciousness one day after his hemodialysis session. Physical exam was significant for hypotension and hypoxia with no focal neurologic deficits. Computed tomography (CT) scan of head showed gas in cerebral venous circulation. The patient did not undergo any procedures prior to presentation, and his last hemodialysis session was uneventful. Retrograde rise of venous air to the cerebral circulation was the likely mechanism for venous CAE. The second patient was a 46-year-old female presenting with fever, shortness of breath, and hematemesis. She was febrile, tachypneic, and tachycardic and required intubation and mechanical ventilation. An orogastric tube inserted drained 2500 mL of bright red blood. Flexible laryngoscopy and esophagogastroduodenoscopy were performed. She also underwent central venous catheter placement. CT scan of head performed the next day due to absent brain stem reflexes revealed intravascular air within cerebral arteries. A transthoracic echocardiogram with bubble study ruled out patent foramen ovale. The patient had a paradoxical CAE in the absence of a patent foramen ovale. PMID:27635266

    We retrospectively analyzed the autopsy records of the Institute of Forensic Medicine during the five-year period between 1998 and 2002 to document the characteristics of fatalities resulting from hanging which is the commonest mode of suicide in Istanbul. Upon analysis of death scene investigation and autopsy reports together with the information gathered from the police, the cases of hanging fatalities of suicidal origin were selected. Seven hundred sixty one hanging cases of suicidal origin were detected and evaluated in terms of demographic features, the type of hanging material used for ligature, cause of death, internal findings in neck organs, other traumatic findings suggesting the use of another method for suicide, toxicological findings and microscopic findings in delayed death cases. In 364 of these cases suspension was complete and in 397 incomplete. Five hundred thirty seven of those (70.56%) were male and 224 (29.44%) were female. The preponderance of male cases in our autopsy population was also detected in suicidal hanging cases. There was no case aged lower 10 and the number of the cases in the age group of cases aged over 80 was the lowest (n=3, 0.4%). In 634 of cases, the place of hanging was the subject's own house, most victims selected rope (652 cases) for the ligature with the rest using sheet, belt, cable and necktie. There were traumatic findings showing attempts of suicide other than hanging in 24 cases (tentative marks in 22 cases and non-fatal burning in 2). In 23 of cases, there were bruises of different ages. In these cases females constituted the majority suggesting violence against women that is a social problem in various cultural subgroups of our country. This violence may have played a role in the decision of suicide. Superficial bruises were detected in 56 cases and were attributed to the trauma. Fractures in neck organs were detected in 446 of cases. In fracture-determined cases, fracture in hyoid bone was seen in 177, in

    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.

    Candida species have been implicated as significant contributors to morbidity in the neonatal period and are associated with 25-50% of mortality in invasive neonatal candidiasis. Peritoneal candidiasis, being paucisymptomatic, cannot often be correctly identified in a preterm neonate. The correct approach to diagnosis of neonatal peritoneal candidiasis is taking into account the epidemiology along with a strong clinical suspicion and appropriate timely diagnostic interventions. We report a case of fatal neonatal peritoneal candidiasis which was misdiagnosed as mucormycosis.

    Suspicion of Brazilian spotted fever (BSF) should occur in endemic regions upon surveillance of the acute febrile icteric hemorrhagic syndrome (AFIHS). However, limitations associated with currently available laboratory tests pose a challenge to early diagnosis, especially in fatal cases. Two real-time PCR (qPCR) protocols were evaluated to diagnose BSF in 110 fatal AFIHS cases, collected in BSF-endemic regions in 2009-2010. Of these, 24 were positive and 86 negative by indirect immunofluorescence (IFA) assay (cut-off IgG and/or IgM ≥ 128). DNA from these samples was used in the qPCR protocols: one to detect Rickettsia spp. (citrate synthase gene) and another to determine spotted fever group (SFG) Rickettsia species (OmpA gene). Of the 24 IFA-positive samples, 5 (21%) were positive for OmpA and 9 (38%) for citrate synthase. In the IFA-negative group (n=86), OmpA and citrate synthase were positive in 23 (27%) and 27 (31%), respectively. These results showed that the 2 qPCR protocols were about twice as sensitive as the IFA test alone (93% concordance). In conclusion, qPCR is a sensitive method for the diagnosis of fatal BSF cases and should be considered for routine surveillance of AFIHS in places like Brazil, where spotted fever-related lethality is high and other endemic diseases like dengue and leptospirosis can mislead diagnosis.

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

    Over the past several years, Medical Examiners in Kentucky and around the nation have observed a dramatic rise in drug intoxication deaths involving the prescription medication methadone. This documented rise in methadone-related deaths requires a better understanding of methadone's pathophysiology and the ways it contributes to significantly increase morbidity and mortality. This study reviews 176 fatalities ascribed to methadone toxicity by the Office of the Chief Medical Examiner in Kentucky between 2000 and 2004. Postmortem toxicological analysis recorded a more than 10-fold increase in methadone toxicity fatalities, rising from 6 cases in 2000 to 68 cases in 2003. Of the 176 methadone-related fatalities, methadone was the only drug detected in postmortem blood and urine toxicological analyses in 11 (6.25%) cases. The mean methadone blood concentration of all 176 cases was 0.535 mg / L (0.02-4.0). The following psychoactive medications were detected: antidepressants (39.8%), benzodiazepines (32.4%), and other opioids in addition to methadone (27.8%). Cannabinoids were detected in 44 (28.4%) cases and cocaine or metabolite in 34 (21.9%) cases. Of the 95 cases with a known history of methadone use, 46 (48.4%) involved prescription by private physician. The interpretation of blood methadone concentrations alone or combined with other psychoactive drugs requires consideration of the subject's potential chronic use of and tolerance to the drug. A thorough investigation into the practices of procurement and use/abuse of methadone is essential to arrive at the proper designation of the cause of death.

    In the order Hymenoptera, bees, hornets, and wasps are well-known stinging insects whose envenoming can be fatal. Their stinging attacks are common in rural and forested areas of Sri Lanka. However, fatal stinging by the large-bodied carpenter bees is unreported. We report the first known case of a fatal sting by the large carpenter bee, Xylocopa tranquebarica, in a forested area in Puttalam (North Western Province) in the dry zone of Sri Lanka. A 59-year-old healthy male manual laborer accompanied by a fellow worker had been fixing a fence on a coconut estate bordering a forested area when a flying insect emerged from a dead tree trunk and stung him on his face. His coworker, who was watching the incident, killed the insect. The victim complained of immediate intense pain in the face and collapsed on the ground just after resuming work after 10 minutes of resting. He was found dead on admission to the hospital 90 minutes later. Autopsy showed normal coronary arteries and heart, but the lungs were slightly congested and contained secretions in the bronchi. Acute anaphylaxis was the most likely cause of death. This case presents the habitat, morphology, attack pattern, and the medical importance of large carpenter bees. PMID:27061039

    Paramethoxyamphetamine (PMA) is a phenethylamine derivative that is structurally related to 3,4-methylenedioxymethamphetamine (MDMA), but has higher toxicity than MDMA. Here, we report a fatal intoxication case involving PMA. A 36-year-old man was found dead in a hotel room. Toxicological analysis revealed that PMA concentrations were 0.57 and 0.59mg/L in peripheral and heart blood, respectively. Ketamine and diazepam were also detected in his blood. Based on toxicological results and autopsy findings, the cause of death was determined to be acute fatal intoxication with PMA. Hair analysis using gas chromatography/mass spectrometry was performed and PMA was detected at a concentration of 20.1ng/mg after methanol extraction for 20h. This is the first report of the determination of PMA concentration in the hair from a drug abuser. PMID:27396905

    We report a fatal case of gastrointestinal perforation and hemorrhage secondary to the ingestion of a foreign body. While engaged in an amateur futsal competition, an apparently healthy young man suddenly collapsed and his respiration ceased. Autopsy revealed a 3-mm circular perforation on the gastric wall fundus with a significant amount of clotted blood within the gastric lumen. On inspection, a foreign body consisting of a bristle-like hair, later identified via electron microscopy to be a cat vibrissa, i.e. a whisker, was found along the perforation margin. Thus, the inadvertent ingestion of fine, sharp objects (even a cat whisker) can lead to gastric perforation and bleeding, which might prove fatal under given circumstances. PMID:27183326

    Background Anaphylaxis is a serious allergic reaction that may cause death; however, the actual risk of death is unclear. Objective To estimate the case fatality rate (CFR) among hospitalizations or emergency department (ED) presentations for anaphylaxis and the mortality rate associated with anaphylaxis for the general population. Methods This was a population-based epidemiologic study using 3 national databases: Nationwide Inpatient Sample (NIS, 1999-2009), Nationwide Emergency Department Sample (NEDS, 2006-2009), and Multiple Cause of Death Data (MCDD, 1999-2009). Sources for these databases are hospital, ED discharge records and death certificates, respectively. Results CFRs were between 0.25% and 0.33% among hospitalizations or ED presentations with anaphylaxis as the principal diagnosis (NIS+NEDS, 2006-2009). These rates represent 63 to 99 deaths per year in the United States, approximately 77% of which occurred in hospitalized patients. Rate of anaphylaxis hospitalizations rose from 21.0 to 25.1 per million population between 1999 and 2009 (annual percent change 2.23%; 95% CI: 1.52%–2.94%), contrasting with a declining CFR among hospitalizations (annual percent change –2.35%; 95% CI: –4.98% to 0.34%). Overall mortality rates ranged from 0.63 to 0.76 per million population (186 to 225 deaths per year, MCDD), and appeared stable in the last decade (annual percent change: –0.31%; 95% CI, –1.54% to 0.93%). Conclusion From 2006 to 2009, the overwhelming majority of hospitalizations or ED presentations for anaphylaxis did not result in death, with an average CFR of 0.3%. Anaphylaxis-related hospitalizations rose steadily in the last decade (1999-2009), but this increase was offset by the declining CFR among those hospitalized; both inpatient and overall mortality rates associated with anaphylaxis appeared stable and were well under 1 per million population. Although anaphylactic reactions are potentially life threatening, the probability of dying is

    Hand, foot and mouth disease (HFMD) associated with enterovirus 71 (EV71) is a growing public health concern. This study aimed to estimate the case-fatality of HFMD associated with EV71 on the basis of a meta-analysis. We searched PubMed, Cochrane, Web of Science, Elsevier, CNKI, Wanfang, and VIP databases. Two authors independently selected relevant studies. The pooled estimate of case-fatality was calculated using a random-effects model. Potential sources of heterogeneity were explored using subgroup analysis, sensitivity analysis and meta-regression. We identified 14 eligible studies with a total population of 112 546. The random-effects pooled case-fatality was 1·7% (95% confidence interval 1·2-2·4). The funnel plot was asymmetrical. The estimate of case-fatality was highest in mainland China (1·8%). Removal of eight local Chinese studies decreased the original estimate. The pooled case-fatality in the period of 1998-2007 (1·5%) was lower than that in the period 2008-2012 (1·8%). Control measures for HFMD associated with EV71 are essential because of the increased case-fatality over time, especially in East Asia.

    The influenza epidemic in 2015–2016 in Russia is characterized by a sharp increase of influenza cases (beginning from the second week of 2016) with increased fatalities. Influenza was confirmed in 20 fatal cases registered among children (0–10 years), in 5 cases among pregnant women, and in 173 cases among elderly people (60 years and older). Two hundred and ninety nine people died from influenza were patients with some chronic problems. The overwhelming majority among the deceased (more than 98%) were not vaccinated against influenza. We isolated 109 influenza A(H1N1)pdm09 and one A(H3N2) virus strains from 501 autopsy material samples. The antigenic features of the strains were similar to the vaccine strains. A phylogenic analysis of hemagglutinin revealed that influenza A(H1N1)pdm09 virus strains belonged to 6B genetic group that had two main dominant subgroups during the 2015–2016 season. In Russia strains of the first group predominated. We registered an increased proportion of strains with D222G mutation in receptor-binding site. A herd immunity analysis carried out immediately prior to the epidemic showed that 34.4% blood sera samples collected in different regions of Russia were positive to A/California/07/09(H1N1)pdm09. We came to a conclusion that public awareness enhancement is necessary to reduce unreasonable refusals of vaccination. PMID:27776172

In present study, 149 fatal firearm injuries from 2002 to 2011 were reviewed. At total of 7126 autopsies, fatal firearm injuries comprised of 2.09% (n = 149) of total autopsies cases. Among those victims, 136 were male (91.3%), 13 (8.7%) were female. The youngest age of victim was 10 years and the oldest was 79 years. Mean age of the victims was 33.79 years and median age was 30 years. Outdoor incident was the most common scene of crime. Night time incident (18:00 PM-05:59 AM) was higher than day time one. Most of the cases occurred in week ends (n = 52). Homicide (77.2%) was the most frequent manner of death. Head/face and chest were the most common sites of entrance. The autopsy report also study on entrance wound, range and types of projectiles. Blood alcohol concentration was examined in 122 cases and 38 victims showed positive results, 11 cases revealed using of illegal substances in blood and urine analysis. This study also included the association between manner of death and other factors. Age group, time of incidence, place of incidence, number of entrance wound and range showed statistically significant association with manner of death.

    Encephalitis due to BK virus is a rare condition. Here, we describe a young male patient with common variable immunodeficiency who developed fatal encephalitis due to BK virus. The patient presented initially with ocular symptoms that were followed by behavioral changes and spastic quadriparesis. Diagnosis was made by the compatible clinical findings and detection of viral DNA by polymerase chain reaction in the cerebrospinal fluid. To the best of our knowledge, this is the first report of BK virus encephalitis in a patient with common variable immunodeficiency. We suggest that BK virus should be suspected in cases of encephalitis; particularly in patients with immunodeficiency.

A 7-year-old male presented with cardiac arrest and was found to have a serum magnesium level of 41.2 mg/dL (33.9 mEq/L) after having received an Epsom salt enema earlier that day. The medical history of Epsom salt, the common causes and symptoms of hypermagnesemia, and the treatment of hypermagnesemia are reviewed. The easy availability of magnesium, the subtle initial symptoms of hypermagnesemia, and the need for education about the toxicity of magnesium should be of interest to physicians. PMID:15759964

    Immersion pulmonary oedema (IPE) is being increasingly recognized in swimmers, snorkellers and scuba divers presenting with acute symptoms of respiratory distress following immersion, but fatal case reports are uncommon. We report two fatal cases of probable IPE in middle-aged women, one whilst snorkelling and the other associated with a scuba dive. In the snorkeller's case, an episode of exercise-related chest tightness and shortness of breath that occurred 10 months previously was investigated but this proved negative, and she was on no medications. However, at autopsy, moderate left ventricular hypertrophy was noted. The scuba diver had suffered several previous episodes of severe shortness of breath following dives, one being so severe it led to cyanosis and impaired consciousness. At inquest, the pathologist's diagnosis was given as drowning and IPE was not mentioned. Expert input from doctors trained in diving medicine should be compulsory in the investigation of diving deaths, and forensic pathologists should be properly trained in and have guidelines for the conduct of post-immersion and post-diving autopsies.

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

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

    Hemorrhagic complications of acute leukemia are well described and are a common cause of mortality in these patients. However, to our knowledge, fatal intracerebral hemorrhage (ICH) as an initial presentation of acute lymphocytic leukemia (ALL) has only been reported once. We report a case of previously undiagnosed ALL presenting with ICH. Our patient is a 17-year old male who was found unresponsive several hours after complaining of headache. Initial emergency room evaluation found the patient to have anisocoria with a fixed and dilated right pupil and demonstrated evidence of decorticate posturing. Imaging revealed a large right-sided intraparenchymal hemorrhage, intraventricular hemorrhage, midline shift, and uncal herniation. Laboratory evaluation showed marked leukocytosis with blastic predominance and evidence of disseminated intravascular coagulopathy. Emergent surgical intervention was performed. However, despite evacuation of the hematoma, the patient eventually progressed to clinical brain death. Usually, ICH is seen in ALL patients after the diagnosis has been made. We report a unique case of fatal intracranial hemorrhage as the initial presentation of ALL and discuss the possible management dilemmas to treat such entities. ALL should be kept in the broad differential diagnosis of spontaneous ICH, especially in a young patient with evidence of severe coagulopathy.

  11. Estimated rate of fatal automobile accidents attributable to acute solvent exposure at low inhaled concentrations.

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

    Fatal familial insomnia (FFI) is a hereditary prion disease caused by a mutation in codon 178 of the prion protein gene PRNP on chromosome 20. It is characterized by disturbed night sleep, resulting in daily vigilance perturbations and a variety of other neurological symptoms. We present the case of a 46-year-old woman deteriorating despite immunosuppressive treatment which was initiated suspecting cerebral vasculitis as the cause of her progressive neurological symptoms. The correct diagnosis was established only post mortem. Based on the case presented here, we discuss typical clinical symptoms and imaging findings. In particular, we outline how modern diagnostic methods such as positron emission tomography with [(15)O]H(2)O and [(18)F]FDG and single photon emission computed tomography can add valuable information to results from conventionally performed imaging techniques and genetic testing.

    The current report describes the diagnostic features in 10 cases of acute fatal canine leptospirosis with minimal renal and hepatic changes that may present a diagnostic challenge for the pathologist. Most affected dogs were less than 6 months of age and had a biochemical profile consistent with hepatorenal dysfunction. Clinical signs consisted of vomiting, depression, icterus, dehydration, diarrhea, and anorexia. All dogs died or were humanely euthanized within 3-7 days after the onset of clinical disease. Necropsy findings included pulmonary edema with hemorrhages, icterus, renal and hepatic pallor and swelling, and gastric edema with hemorrhage. Despite severe azotemia, histological changes in the kidneys were subtle in all dogs, and included mild renal tubular simplification, with single-cell necrosis and attenuation, along with minimal interstitial lymphoplasmacytic inflammation, edema, and hemorrhage. Hepatic lesions included scattered hepatocellular single-cell necrosis and hepatocellular dissociation. Prominent extrarenal lesions typically associated with uremia including vascular fibrinoid necrosis in multiple organs, pulmonary mineralization with occasional fibrinosuppurative exudation, and gastric mineralization were also present. Postmortem diagnostic confirmation was based on the detection of leptospiral antigen on fresh renal samples by fluorescent antibody test and on the demonstration of intact spirochetes in sections of kidneys using immunohistochemical staining. Acute fatal canine leptospirosis occurred as a fulminant hepatorenal disease affecting mainly young dogs, and the diagnosis was dependent on the recognition of the subtle renal changes with confirmation via fluorescent antibody testing or immunohistochemical staining.

    We present the first reported fatality from argon gas emboli during prostate cryosurgery. The decedent underwent cryotherapy for prostate carcinoma using cryoablation probes which were cooled with argon and nitrous oxide and warmed with helium. Minutes into the procedure he experienced sudden cardiovascular collapse and could not be resuscitated. Postmortem examination was performed at the request of family and healthcare providers. Collection of tissues and blood samples had to be conducted carefully to capture suspected noble gases,argon, and helium. Specimens were submitted to Saint Louis University Forensic Toxicology Laboratory for toxicological examination and for evaluation of the composition of the gas retrieved from the vascular system.Gas chromatography mass spectrometric analyses confirmed argon in blood, brain, liver, and gas retrieved from the aorta. These samples had significant argon compared with room air also sent for comparison. The manner of death was accident. To date, there have been no intraoperative surgical fatalities reported from prostatic cryotherapy. We report such an unfortunate death to raise awareness in the medical community. We also describe how to collect and handle blood and tissue samples to submit for toxicological analysis in cases of volatile gas emboli. PMID:22442836

    A 65-year-old woman died three days after being involved in a traffic accident, following an episode of ventricular fibrillation. She was diagnosed as having suffered cardiac contusion, liver contusion, mediastinal hematoma and rib fracture on admission. Her electrocardiogram showed complete right bundle branch block, complete atrioventricular block, and right axis deviation. Aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase and creatine kinase-MB were found to be elevated on biochemical blood analysis. These findings recovered and her condition appeared to improve daily. At autopsy, epicardial and intramyocardial haemorrhage were macroscopically seen in the posterior wall of the bilateral ventricles. On microscopic examination, there was evidence of fresh haemorrhage and coagulative necrosis with inflammatory reaction in the ordinary myocardium and adipose tissue around the atrioventricular node, which had spread to the proximal portion of the His' bundle. It is considered that these findings caused ventricular fibrillation to occur, and that the cause of death in this case was myocardial contusion due to blunt thoracic injury. This case would indicate that myocardium nearby atrioventricular junction is vulnerable to external force. Moreover, it would seem that fatal arrhythmia occasionally occurs during the follow-up stage, despite the lack of any significant clinical findings. PMID:15573975

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

    The research compound 25I-NBOMe, also known as CIMBI-5 or INBMeO, was created in academic laboratories as a potent serotonin 2A receptor agonist. Because of its high affinity and ambiguous legal status, recreational drug enthusiasts have used this compound as a powerful alternative to other hallucinogenic drugs such as lysergic acid diethylamide. We report 2 deaths after 25I-NBOMe ingestion by decedents who attended separate "rave" parties. The first case involved a 21-year-old male who admitted taking "acid" to his friend. A sudden violent rage caused him to flail about, and he subsequently became unresponsive. The postmortem examination revealed numerous external injuries that were consistent with physical aggression. The second case involved a 15-year-old female who was socializing outside a rave party, became ill, and rapidly deteriorated as her friend transported her to the hospital. The postmortem assessment was similar to the first case in that external contusions featured prominently. Comprehensive toxicology screens in both cases revealed only evidence of marijuana use. A deeper analysis using time-of-flight mass spectrometry revealed the presence of 25I-NBOMe, which was further confirmed by tandem-mass spectrometry. The behavior and injuries in these cases reveal a consistent pattern preceding fatal 25I-NBOMe toxicity.

    Erysipelas is a generally benign superficial bacterial skin infection, and its bullous form constitutes a rare and more severe variant. We describe the first and fatal case of “bullous erysipelas-like” septic vasculitis due to Pseudomonas bacteremi. A 69-year-old Chinese man presenting with diarrhea and septic shock initially began to rapidly develop sharply defined erythematous plaques with non-hemorrhagic bullae over his lower limbs. Culture of the aspirate from the bullae was positive for Pseudomonas aeruginosa. This was also consistent with his blood cultures showing Pseudomonas bacteremia. Histology of the skin lesion showed microthrombi and neutrophilic infiltrates in blood vessels with Gram-negative bacilli extruding from the vessel walls, characteristic of septic vasculitis. The bullous erysipelas-like lesions seen in this patient represents a rare manifestation of both septic vasculitis and Pseudomonas infection. PMID:26955132

    In this case report, we present an evaluation of the distribution of postmortem concentrations of acetyl fentanyl in a fatality attributed to the drug. A young man who had a history of heroin abuse was found deceased at his parents' home. Toxicology testing, which initially screened positive for fentanyl by ELISA, subsequently confirmed acetyl fentanyl by gas chromatography-mass spectrometry specific ion monitoring (GC-MS SIM) analysis following liquid-liquid extraction. No other drugs or medications, including fentanyl, were detected. The acetyl fentanyl peripheral blood concentration was quantified at 260 ng/mL compared with the central blood concentration of 250 ng/mL. The liver concentration was 1,000 ng/kg, the vitreous was 240 ng/mL and the urine was 2,600 ng/mL. The cause of death was certified due to acute acetyl fentanyl intoxication, and the manner of death was certified as an accident.

    Streptococcus suis is a recognized pathogen that may cause important diseases in pigs and humans. This microorganism has been repeatedly isolated from wild boar (Sus scrofa). However, its health implications for this wild species are still unknown. This article reports a detailed description of a fatal case of septicemia by S. suis affecting a young wild boar. The affected animal, about 15 days old, was found near death and exhibiting neurologic signs at a wild boar estate in southwestern Spain. Postmortem examination showed generalized congestion, brain hemorrhages and lobular pneumonia. Histopathological evaluation demonstrated the presence of meningitis and encephalitis with marked congestion and suppurative bronchopneumonia. Streptococcus suis serotype 2 isolates exhibiting important virulence factors (extracellular factor, muramidase-released protein, and suylisin) were isolated from the affected animal. This study confirms the presence of potentially virulent and zoonotic strains of S. suis in wild boar from Spain. PMID:26056897

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

  3. Application of permanents of square matrices for DNA identification in multiple-fatality cases

    PubMed Central

    2013-01-01

    Background DNA profiling is essential for individual identification. In forensic medicine, the likelihood ratio (LR) is commonly used to identify individuals. The LR is calculated by comparing two hypotheses for the sample DNA: that the sample DNA is identical or related to a reference DNA, and that it is randomly sampled from a population. For multiple-fatality cases, however, identification should be considered as an assignment problem, and a particular sample and reference pair should therefore be compared with other possibilities conditional on the entire dataset. Results We developed a new method to compute the probability via permanents of square matrices of nonnegative entries. As the exact permanent is known as a #P-complete problem, we applied the Huber–Law algorithm to approximate the permanents. We performed a computer simulation to evaluate the performance of our method via receiver operating characteristic curve analysis compared with LR under the assumption of a closed incident. Differences between the two methods were well demonstrated when references provided neither obligate alleles nor impossible alleles. The new method exhibited higher sensitivity (0.188 vs. 0.055) at a threshold value of 0.999, at which specificity was 1, and it exhibited higher area under a receiver operating characteristic curve (0.990 vs. 0.959, P = 9.6E-15). Conclusions Our method therefore offers a solution for a computationally intensive assignment problem and may be a viable alternative to LR-based identification for closed-incident multiple-fatality cases.

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.

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

    A body packer is an important means of drug trafficking. While drug packets are inside the body, they can leak or rupture causing acute substance toxicity. Most of the reports of body packer syndrome have come from Europe and North America, which are destination targets. In the present study, the authors reported two cases of fatal heroin body packers from the northern part of Thailand. Both cases were foreign tourists who came to Chiang Mai and stayed in a hotel or a guesthouse room in which the deaths occurred. The autopsy findings revealed rupturing of heroin packages in the stomach. The packaging used in both cases was not sophisticated. The powder was packed inside condoms without extra covering, as observed in some other professional packers. The amount of heroin transported was about 30-50 gm. The purity of heroin in this powder was about 50-90%. Their destinations were their home countries and not directly to Europe or North America. Deaths occurred just prior to their return. The cause of death was a heroin overdose. A significant level of heroin metabolites, 6-MAM and morphine were detected in the blood and urine. PMID:16583590

    Carbofuran is a broad spectrum carbamate insecticide which inhibits cholinesterase. In the recent past several carbofuran related homicide and suicide cases were reported in Sri Lanka. The concentration of carbofuran found in blood, bile and/or tissues in eight fatal cases were presented in this paper. Liquid-liquid extraction with chloroform was carried out with tissue and beverage samples while blood and bile samples were roller mixed with n-hexane and finally extracted into acetonitrile. Qualitative analysis of carbofuran in biological specimens was carried out using TLC and GC-MS. Presence of carbofuran and its metabolite carbofuran phenol were confirmed by GC-MS. The quantitative analysis was carried out using a validated method where Zorbax Eclips XDB C18 column was used in HPLC with photo diode array detector and GC-MS. In blood, bile, liver and stomach contents/stomach and contents both carbofuran and carbofuran phenol were identified, while in certain cases only the metabolite, carbofuran phenol was identified in blood. The carbofuran levels ranged from 0.4 to 18 μg/ml in blood, 0.4 to 60 μg/ml in bile, 2.2 μg/g in liver and 0.3 to 300 μg/g in stomach contents/stomach and contents.

    Tapeworms of the genus Echinococcus reside in the small intestine of a number of carnivorous species, predominantly canids. In enzootic areas, hydatidosis caused by taeniid metacestodes can present a significant problem in accidental intermediate hosts, including humans. Whereas the United Kingdom is currently considered free of Echinococcus multilocularis, Echinococcus granulosus sensu stricto (s.s.) and Echinococcus equinus are endemic in the UK and have been reported in a variety of captive mammals. The presentation of echinoccocosis in non-human primates widely parallels disease in humans, and public health concerns are related to the four genera, E. granulosus, E. multilocularis, Echinococcus vogeli and Echinococcus oligarthrus. In contrast, sporadic outbreaks and individual hydatid disease cases in non-human primates have been associated with several Echinococcus and Taenia species. Here we describe three fatal cases of cystic echinococcosis in two captive ring-tailed lemurs (Lemur catta) and one captive red-ruffed lemur (Varecia variegata rubra) and provide molecular tapeworm characterisation. To the best of the authors' knowledge, this includes the first report of Echinococcus ortleppi in a UK born ring-tailed lemur and provides the first in depth case reports of echinococcosis due to E. equinus in UK born ring-tailed and red ruffed lemurs with detailed clinical and pathological findings. The cestode life cycle and implications for zoo collections are discussed. PMID:26872922

    A small focus of hemorrhagic fever (HF) cases occurred near Cochabamba, Bolivia, in December 2003 and January 2004. Specimens were available from only one fatal case, which had a clinical course that included fever, headache, arthralgia, myalgia, and vomiting with subsequent deterioration and multiple hemorrhagic signs. A non-cytopathic virus was isolated from two of the patient serum samples, and identified as an arenavirus by IFA staining with a rabbit polyvalent antiserum raised against South American arenaviruses known to be associated with HF (Guanarito, Machupo, and Sabiá). RT-PCR analysis and subsequent analysis of the complete virus S and L RNA segment sequences identified the virus as a member of the New World Clade B arenaviruses, which includes all the pathogenic South American arenaviruses. The virus was shown to be most closely related to Sabiá virus, but with 26% and 30% nucleotide difference in the S and L segments, and 26%, 28%, 15% and 22% amino acid differences for the L, Z, N, and GP proteins, respectively, indicating the virus represents a newly discovered arenavirus, for which we propose the name Chapare virus. In conclusion, two different arenaviruses, Machupo and Chapare, can be associated with severe HF cases in Bolivia.

    Background Bulgaria's official stroke mortality rates are higher for rural than urban areas. Official mortality data has indicated that these rates are amongst the highest in Europe. There has been a lack of studies measuring stroke incidence in urban and rural populations. Methods We established intensive notification networks covering 37791 residents in Varna city and 18656 residents (55% of them village-dwellers), all aged 45 to 84, in 2 rural districts. From May 1, 2000 to April 30, 2001 frequent contact was maintained with notifiers and death registrations were scanned regularly. Suspected incident strokes were assessed by study neurologists within a median of 8 days from onset. Results 742 events were referred for neurological assessment and 351 of these, which met the WHO criteria for stroke, were in persons aged 45 to 84 and were first ever in a lifetime. Incidence rates, standardised using the world standard weights for ages 45 to 84, were 909 (/100000/year) (95% CI 712–1105) and 597 (482–712) for rural and urban males and 667 (515–818) and 322 (248–395) for rural and urban females. Less than half were admitted to hospital (15% among rural females over 65). Twenty-eight day case fatality was 35% (123/351) overall and 48% (46/96) in village residents. The excess case fatality in the villages could not be explained by age or severity. Conclusions Rural incidence rates were over twice those reported for western populations but the rate for urban females was similar to other western rates. The high level and marked heterogeneity in both stroke incidence and case fatality merit further investigation. PMID:12323079

    This report describes the case of a man who developed fatal sigmoid volvulus that was identified on postmortem radiography before forensic autopsy. Postmortem radiography is useful for visualizing the body prior to autopsy. We discuss postmortem multidetector computed tomography that was tailored for optimum image quality to allow reconstruction of the fatal findings in multiple axes and in three dimensions, helping to pinpoint the anatomical sites of interest. This involves techniques such as manipulation of the scanning beam pitch and overlapping CT section acquisition. These techniques are best performed by personnel with CT technology training.

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

DRESS syndrome is a severe adverse drug-induced reaction presenting as a diffuse maculopapular skin rash with fever, hematological abnormalities (leukocytosis, eosinophilia, and/or atypical lymphocytosis), and multiorgan involvement. In our patient, diagnosis of DRESS was confirmed by the presence of six of the seven diagnostic criteria established in 2006 by the Japanese Research Committee on Severe Cutaneous Adverse Drug Reaction: maculopapular skin rash developing at least 3 weeks after starting therapy with a limited number of drugs, prolonged clinical symptoms after discontinuation of the causative drug, lymphadenopathy, fever, leukocyte abnormalities, and liver abnormalities. The diagnostic criteria of human herpesvirus (HHV)-6 reactivation have not been fulfilled in our patient, but a HHV-7 active infection was demonstrated by the presence of HHV-7 DNA and IgM in the patient's serum. In fact, in some DRESS instances, reactivation of HHVs other than HHV-6 may be detected, including HHV-7, Epstein-Barr virus (EBV), and cytomegalovirus (CMV). Our case underlines that not only HHV-6 but also HHV-7 systemic reactivation may be associated with a more severe and even fatal course of this syndrome. PMID:26519419

    In 1987, an isolated case of fatal Marburg disease was recognized during routine clinical haemorrhagic fever virus surveillance conducted in Kenya. This report describes the isolation and partial characterization of the new Marburg virus (strain Ravn) isolated from this case. The Ravn isolate was indistinguishable from reference Marburg virus strains by cross-neutralization testing. Virus particles and aggregates of Marburg nucleocapsid matrix in Ravn-infected vero cells, were visualized by immunoelectron microscopic techniques, and also in tissues obtained from the patient and from inoculated monkeys. The cell culture isolate produced a haemorrhagic disease typical of Marburg virus infection when inoculated into rhesus monkeys. Disease was characterized by the sudden appearance of fever and anorexia within 4 to 7 days, and death by day 11. Comparison of nucleotide sequences for portions of the glycoprotein genes of Marburg-Ravn were compared with Marburg reference strains Musoki (MUS) and Popp (POP). Nucleotide identity in this alignment between RAV and MUS is 72.3%, RAV and POP is 71%, and MUS and POP is 91.7%. Amino acid identity between RAV and MUS is 72%, RAV and POP is 67%, and MUS and POP is 93%. These data suggest that Ravn is another subtype of Marburg virus, analogous to the emerging picture of a spectrum of Ebola geographic isolates and subtypes. PMID:8800792

    INTRODUCTION Acinetobacter baumannii is usually associated with respiratory tract, urinary tract and bloodstream infections. Recent reports suggest that it is increasingly causing skin and soft tissue infections. It is also evolving as a multidrug resistant organism that can be difficult to treat. We present a fatal case of multidrug resistant A. baumannii soft tissue infection and review of relevant literature. PRESENTATION OF CASE A 41 year old morbidly obese man, with history of alcoholic liver disease presented with left superficial pre-tibial abrasions and cellulitis caused by multidrug resistant (MDR) A. baumannii. In spite of early antibiotic administration he developed extensive myositis and fat necrosis requiring extensive and multiple surgical debridements. He deteriorated despite appropriate antibiotic therapy and multiple surgical interventions with development of multi-organ failure and died. DISCUSSION Managing Acinetobacter infections remains difficult due to the array of resistance and the pathogens ability to develop new and ongoing resistance. The early diagnosis of necrotizing soft tissue infection may be challenging, but the key to successful management of patients with necrotizing soft tissue infection are early recognition and complete surgical debridement. CONCLUSION A. baumannii is emerging as an important cause of severe, life-threatening soft tissue infections. Multidrug resistant A. baumannii soft tissue infections may carry a high mortality in spite of early and aggressive treatment. Clinicians need to consider appropriate early empirical antibiotic coverage or the use of combination therapy to include MDR A. baumannii as a cause of skin and soft tissue infections. PMID:25016080

    Fatal familial insomnia (FFI) is a prion disease exhibiting the PRNP D178N/129M genotype. Features of this autosomal dominant illness are progressive insomnia, dysautonomia, myoclonus, cognitive decline and motor signs associated with thalamic nerve cell loss and gliosis. In contrast to the new variant of Creutzfeldt-Jakob disease (vCJD) the onset of FFI is in middle to late adulthood. We report two male patients who belong to a large German FFI kindred. They were examined clinically, and postmortem neuropathological examination was carried out in collaboration with the German reference centre for prion disease. Additionally, the prion protein gene (PRNP) was analysed. To identify further patients with disease onset under 30 years of age a comprehensive literature review was carried out. Two male patients presented with typical symptoms of FFI at the age of 23 and 24 years. In their kindred, the age of onset has never before been under 44 years of age. Our literature review identified five additional early onset cases who died at age 21 to 25 years. In all 22 reviewed FFI families the median manifestation age was 49.5 years. Although phenotypic variability of FFI is common, age of onset under 30 years has been considered to be a hallmark of vCJD with a mean manifestation at 27 years of age. Our findings underline that in addition to vCJD, FFI must be considered in cases of young-onset prion disease. This has considerable impact on clinical management and genetic counselling.

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

    Aim To assess the seven-year trends of hospitalization incidence due to acute peptic ulcer hemorrhage (APUH) and associated risk factors, and examine the differences in these trends between two regions in Croatia. Methods The study collected sociodemographic, clinical, and endoscopic data on 2204 patients with endoscopically confirmed APUH who were admitted to the Clinical Hospital Center “Sestre Milosrdnice,” Zagreb and Clinical Hospital Center Split between January 1, 2005 and December 31, 2011. We determined hospitalization incidence rates, 30-day case fatality rate, clinical outcomes, and incidence-associated factors. Results No differences were observed in APUH hospitalization incidence rates between the regions. Age-standardized one-year cumulative APUH hospitalization incidence rate calculated using the European Standard Population was significantly higher in Zagreb than in Split region (43.2/100 000 vs 29.2/100,000). A significantly higher APUH hospitalization incidence rates were observed in the above 65 years age group. Overall 30-day case fatality rate was 4.9%. Conclusion The hospitalization incidence of APUH in two populations did not change over the observational period and it was significantly higher in the Zagreb region. The incidence of acute duodenal ulcer hemorrhage also remained unchanged, whereas the incidence of acute gastric ulcer hemorrhage increased. The results of this study allow us to monitor epidemiological indicators of APUH and compare data with other countries. PMID:25559836

    We present a case involving a fatality due to the combined ingestion of two different types of antidepressants. A 41-year-old Caucasian male, with a history of depression and suicide attempts, was found deceased at home. Multiple containers of medication, the MAO-inhibitor moclobemide (Aurorix), the SSRI citalopram (Cipramil), and the benzodiazepine lormetazepam (Noctamid) as active substance, as well as a bottle of whiskey were present at the scene. The autopsy findings were unremarkable, but systematic toxicological analysis (EMIT, radioimmunoassay, high-performance liquid chromatography-diode-array detection [HPLC-DAD], gas chromatography-nitrogen-phosphorus detection, and gas chromatography-mass spectrometry) revealed the following: ethanol (0.23 g/L blood, 0.67 g/L urine), lormetazepam (1.65 microg/mL urine), cotinine (0.63 microg/mL blood, 5.08 microg/mL urine), caffeine (1.20 microg/mL urine), moclobemide (and metabolites), and citalopram (and metabolite). There upon, we developed a new liquid chromatographic separation with optimized DAD, preceded by an automated solid-phase extraction, for the quantitation of the previously mentioned antidepressive drugs. The results obtained for blood and urine, respectively, were as follows: Ro 12-5637 (moclobemide N'-oxide) not detected and 424 microg/mL; Ro 12-8095 (3-keto-moclobemide) 2.26 microg/mL and 49.7 microg/mL; moclobemide 5.62 microg/mL and 204 microg/mL; desmethylcitalopram 0.42 microg/mL and 1.22 microg/mL; and citalopram 4.47 microg/mL and 19.7 microg/mL. The cause of death was attributed to the synergistic toxicity of moclobemide and citalopram, both antidepressants, which, by intentional or accidental combined ingestion, can produce a potentially lethal hyperserotoninergic state. Based on the history of the case and pharmacology of the drugs involved, the forensic pathologists ruled that the cause of death was multiple drug intoxication, resulting in a fatal "serotonin syndrome," and that the manner of

    Large Himalayan earthquakes expose rapidly growing populations of millions of people to high levels of seismic hazards, in particular in northeast India and Nepal. Calibrating vulnerability models specific to this region of the world is therefore crucial to the development of reliable mitigation measures. Here, we reevaluate the >15,700 casualties (8500 in Nepal and 7200 in India) from the M w ~8.2, 1934, Bihar-Nepal earthquake and calculate the fatality rates for this earthquake using an estimation of the population derived from two census held in 1921 and 1942. Values reach 0.7-1 % in the epicentral region, located in eastern Nepal, and 2-5 % in the urban areas of the Kathmandu valley. Assuming a constant vulnerability, we obtain, if the same earthquake would have repeated in 2011, fatalities of 33,000 in Nepal and 50,000 in India. Fast-growing population in India indeed must unavoidably lead to increased levels of casualty compared with Nepal, where the population growth is smaller. Aside from that probably robust fact, extrapolations have to be taken with great caution. Among other effects, building and life vulnerability could depend on population concentration and evolution of construction methods. Indeed, fatalities of the April 25, 2015, M w 7.8 Gorkha earthquake indicated on average a reduction in building vulnerability in urban areas, while rural areas remained highly vulnerable. While effective scaling laws, function of the building stock, seem to describe these differences adequately, vulnerability in the case of an M w >8.2 earthquake remains largely unknown. Further research should be carried out urgently so that better prevention strategies can be implemented and building codes reevaluated on, adequately combining detailed ancient and modern data.

    The potential health hazards of handling industrial fish are well documented. Wet fish in storage consume oxygen and produce poisonous gases as they spoil. In addition to oxygen depletion, various noxious agents have been demonstrated in association with spoilage including carbon dioxide, sulphur dioxide, and ammonia. A fatal case of methane and cyanide poisoning among a group of deep sea trawler men is described. Subsequent independent investigation as a result of this case led to the discovery of cyanides as a further potential noxious agent. This is thus the first case in which cyanide poisoning has been recognised as a potentially fatal complication of handling spoiled fish. The previous literature is reviewed and the implications of the current case are discussed. PMID:11064677

    Middle East respiratory syndrome coronavirus (MERS-CoV) infection causes an acute respiratory illness and is associated with a high case fatality rate; however, the pathogenesis of severe and fatal MERS-CoV infection is unknown. We describe the histopathologic, immunohistochemical, and ultrastructural findings from the first autopsy performed on a fatal case of MERS-CoV in the world, which was related to a hospital outbreak in the United Arab Emirates in April 2014. The main histopathologic finding in the lungs was diffuse alveolar damage. Evidence of chronic disease, including severe peripheral vascular disease, patchy cardiac fibrosis, and hepatic steatosis, was noted in the other organs. Double staining immunoassays that used anti-MERS-CoV antibodies paired with immunohistochemistry for cytokeratin and surfactant identified pneumocytes and epithelial syncytial cells as important targets of MERS-CoV antigen; double immunostaining with dipeptidyl peptidase 4 showed colocalization in scattered pneumocytes and syncytial cells. No evidence of extrapulmonary MERS-CoV antigens were detected, including the kidney. These results provide critical insights into the pathogenesis of MERS-CoV in humans.

    This study has been designed in order to identify factors increasing the risk of a fatal outcome when occupational accidents occur. The aim is to provide further evidence for the design and implementation of preventive measures in occupational settings. The Spanish Ministry of Labour registry of occupational injuries causing absence from work includes information on individual and occupational characteristics of injured workers and events. Registered fatal occupational injuries in 2001 (n=539) were compared to a sample of non-fatal injuries in the same year (n=3493). Risks for a fatal result of occupational injuries, adjusted by individual and occupational factors significantly associated, were obtained through logistic regression models. Compared to non-fatal injuries, fatal occupational injuries were mostly produced by trapping or by natural causes, mostly related to elevation and transport devices and power generators, and injured parts of body more frequently affected were head, multiple parts or internal organs. Adjusted analyses showed increased risk of fatality after an occupational injury for males (adjusted odds ratio aOR=10.92; 95%CI 4.80-24.84) and temporary workers (aOR=5.18; 95%CI 2.63-10.18), and the risk increased with age and with advancing hour of the work shift (p for trends <0.01). Injuries taking place out of the usual occupational setting (aOR=2.85, 95%CI 2.27-3.59), or carrying out atypical tasks (aOR=2.08; 95%CI 1.27-3.39) showed increased risks of a fatal result too, as occupational accidents in agricultural or construction companies. These data can help to select and define priorities for programmes aimed to prevent fatal consequences of occupational injuries. PMID:21094305

    This report presents the case of a 67-year-old woman affected by glioblastoma. After a few days of adjuvant therapy with temozolomide and prophylaxis with trimetrophin-sulfamethoxazolo to prevent Pneumocystis Jiroveci, she had progressive and rapid worsening of symptoms with weakness, dyspnea and orthopnea. She had peripheral edema and proximal hyposthenia of the lower limbs. Chest CT showed bilateral ground-glass opacities and laboratory exams revealed hypoxemia and hypocapnia, an initial reduction in platelet and white blood cells, and an elevation of LDH, AST, ALT, and active urinary sediment. Blood cultures, bronchoalveolar lavage (BAL) data and transbronchial biopsy showed no infections, and in particular no evidence of Pneumocystis Jiroveci pneumonia. Histological examination revealed a typical pattern of AIP. She was treated with broad-spectrum antibiotics and high-dose steroids. The symptoms worsened and respiratory failure required mechanical ventilation. The pneumonia was not responsive to medical or invasive care. She died after ten days of hospitalization. At present very little can be found in the literature about lung toxicity caused by temozolomide. This case can be added as a new report describing this risk. The combination therapy with temozolamide and trimetophin-sulfamethoxazolo could have a synergistic action inducing various forms of pulmonary toxicity. ESTABLISHED FACTS: Acute interstitial pneumonia is a common manifestation of lung toxicity caused by drugs. The clinical course is favorable with a good response to corticosteroids. NOVEL INSIGHT: This is the first fatal case of lung toxicity caused by Temozolomide. Clinicians must be aware that a combination therapy including trimetophin-sulfamethoxazolo could have a synergistic action in inducing pulmonary toxicity.

    The incidence of protozoal and helminthic infestations of the central nervous system (CNS) is less than 1%, but these infestations tend to follow a fatal course. They are more common among children, the elderly and immunocompromised individuals. CNS infections due to Entamoeba histolytica have been known for a long time. In recent years, especially in developing countries, there has been an increase in CNS infections due to free-living amebas (FLAs). Acute CNS infection due to Naegleria fowleri, which ends in death within 2-7 days, is termed primary amebic meningoencephalitis (PAM); subacute or chronic CNS infections due to Acanthamoeba spp, Balamuthia mandrillaris, and Sappinia diploidea, which occasionally cause cerebral abscess, are termed granulomatous amebic encephalitis (GAE). This paper presents a case of GAE with abscess formation in a 75-year-old male patient.

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

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

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

    Context Fatal familial insomnia (FFI) is a genetically transmitted neurodegenerative prion disease that incurs great suffering and has neither a treatment nor cure. The clinical literature is devoid of management plans (other than palliative). Part 1 of this article reviews the sparse literature about FFI, including case descriptions. Part 2 describes the efforts of one patient (with the rapid-course Met-Met subtype) who contended with his devastating symptoms and improved the quality of his life. Design Interventions were based on the premise that some symptoms may be secondary to insomnia and not a direct result of the disease itself. Strategies (derived by trial and error) were devised to induce sleep and increase alertness. Interventions included vitamin supplementation, narcoleptics, anesthesia, stimulants, sensory deprivation, exercise, light entrainment, growth hormone, and electroconvulsive therapy (ECT). Results The patient exceeded the average survival time by nearly 1 year, and during this time (when most patients are totally incapacitated), he was able to write a book and to successfully drive hundreds of miles. Conclusion Methods to induce sleep may extend and enhance life during the disease course, although they do not prevent death. It is hoped that some of his methods will inspire further clinical studies. PMID:17406189

    Amiodarone is a widely used and very potent antiarrhythmic substance. Among its adverse effects, pulmonary toxicity is the most dangerous without a causal treatment option. Due to a very long half-life, accumulation can only be prevented by strict adherence to certain dosage patterns. In this review, we outline different safe and proven dosing schemes of amiodarone and compare the incidence and description of pulmonary toxicity. Reason for this is a case of fatal pulmonary toxicity due to a subacute iatrogenic overdosing of amiodarone in a 74-year-old male patient with known severe coronary artery disease, congestive heart failure and ectopic atrial tachycardia with reduced function of kidneys and liver but without preexisting lung disease. Within 30 days, the patient received 32.2 g of amiodarone instead of 15.6 g as planned. Despite early corticosteroid treatment after fast exclusion of all other differential diagnoses, the patient died another month later in our intensive care unit from respiratory failure due to bipulmonal pneumonitis.

In contrast, CMV can cause severe infections with serious consequences in a immunocompromised state typically associated with organ transplants, highly immunosuppressive cancer chemotherapy, advanced HIV infection or treatment with corticosteroids. The incidence and severity of these manifestations of CMV is directly proportional with the degree of cellular immune dysfunction, i.e., CD8+ Cytotoxic T-cell response. Clinical manifestations of CMV can become apparent in different situations including reactivation of CMV from latency, primary infection in a seronegative host, or exposure of a seropositive host to a new strain of CMV. As the clinical signs of CMV in immunodeficient patients are usually sparse, physicians should be highly vigilant about CMV infection, a treatable condition that otherwise is associated with significant mortality. Here we report a rare case of severe gastrointestinal CMV infection with sustained immunodeficiency secondary to treatment with steroids manifesting as fatal duodenal diverticular bleeding.

    Toluene and xylene are aromatic hydrocarbons commonly used as an industrial solvent for the manufacturing of pharmaceuticals, paints, and chemicals. The Occupational Safety and Health Administration has determined that toluene levels of 2000 parts per million (ppm) are considered dangerous to life and health. Several studies have examined the absorption of toluene and xylene following inhalation and oral ingestion in humans. Volatile organic compounds that are absorbed into the blood are distributed throughout the body; in particular, distribution of absorbed toluene and xylene in humans and rodents is characterized by preferential uptake in well-perfused and lipophil tissues such as the brain, liver, lungs, and body fat and also in central nervous system. The available studies indicate that xylenes are rapidly absorbed independently from the kind of exposition. We illustrate a fatal case of self-poisoning by ingestion of varnishes diluting solvents, reporting the identification and quantification of volatile organic compounds (toluene, o-m-p xylene) from human biologic liquids and viscera samples using the Solid-Phase Microextraction-Headspace-Gas Chromatography/Mass Spectrometry to toxicological analysis, and the histopathological findings evaluated in liver, kidney, and lungs.

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

    The use of herbal products in patients with allergic diseases is a special problem and still controversial. But, many people often use herbs to maintain good health. The patients use self-prescribed remedies as medications but do not inform their physicians about herbal use. Unfortunately, some herbal self-medications may have unexpected effects and interactions which may lead to fatal complications. In this report, we describe a female patient who suffered near-fatal anaphylaxis to parsley.

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

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

    To document two cases of patients who were fatally exposed to tetramethylammonium hydroxide (TMAH) on the skin and to establish a rat model to investigate the effects of dermal exposure to TMAH. The charts of two workers who died from occupational accidental exposure to TMAH were reviewed. The 4-hour lethal dose (LD₅₀) of TMAH was determined by applying solutions mimicking the two most common industrially used concentrations (2.38% and 25%) of TMAH to the skin of Sprague-Dawley rats. Exposure of the rat's skin to 2.38% or 25% TMAH generated LD₅₀ values of 85.9 mg/kg and 28.7 mg/kg, respectively. Application of either concentration of TMAH to the skin produced a rapid, significant increase in the rate of respiration. The serum concentrations of tetramethylammonium (TMA) also changed significantly with time of exposure to both concentrations of TMAH. The level of blood urea nitrogen decreased significantly in rats exposed to the 2.38% TMAH, and rats exposed to the 25% solution had a significant decrease in the serum concentration of sodium. Injection of atropine after 5 minutes of exposure did not significantly overcome any of the toxic effects observed with either solution of TMAH. The preliminary results in the rat model indicated that the lethality of TMAH cannot be fully explained by the severity of the patients' chemical burns, and the physiologic effects on respiratory and kidney functions were probably involved.

    Recently, the D222G substitution was observed in the HA of pandemic (H1N1) 2009 viruses isolated from fatal cases in several countries. We made a similar observation in one fatal case in Tunisia showing a D222G substitution in a virus isolate. The man was 47 years old and had no other subjacent pathologies or any known risk factors. He died after three days, suffering from severe respiratory symptoms of flu. The causal link of the D222G substitution in Tunisia with virulence must be verified. Further study is warranted to elucidate the intriguing relationship between the D222G substitution and severe disease. Constant molecular surveillance is important to monitor the pathogenicity of circulating strains and evaluate vaccine efficacy.

    Docetaxel is a chemotherapeutic agent belonging to the taxane family. This drug is widely used to treat cancers. Interstitial lung disease is a rare but serious toxicity due to the high mortality risk. We report a case of a patient with breast cancer who had fatal acute interstitial lung disease after auxiliary chemotherapy with docetaxel. The clinician should be aware of this risk and should consider it in differential diagnosis in patients with respiratory symptoms treated with docetaxel. PMID:27642457

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

    In this case report, we present an evaluation of the distribution of postmortem concentrations of butyr-fentanyl in a fatality attributed principally to the drug. A man who had a history of intravenous drug abuse was found unresponsive on the bathroom floor of his home. Drug paraphernalia was located on the bathroom counter. Toxicology testing, which initially screened positive for fentanyl by enzyme-linked immunosorbent assay, subsequently confirmed butyr-fentanyl, which was then quantitated by gas chromatography-mass spectrometry-specific ion monitoring (GC-MS SIM) analysis following liquid-liquid extraction. The butyr-fentanyl peripheral blood concentration was quantitated at 58 ng/mL compared with the central blood concentration of 97 ng/mL. The liver concentration was 320 ng/g, the vitreous was 40 ng/mL, the urine was 670 ng/mL and the gastric contained 170 mg. Acetyl-fentanyl was also detected in all biological specimens tested. Peripheral blood concentration was quantitated at 38 ng/mL compared with the central blood concentration of 32 ng/mL. The liver concentration was 110 ng/g, the vitreous was 38 ng/mL, the urine was 540 ng/mL and the gastric contained <70 mg. The only other drug detected was a relatively low concentration of benzoylecgonine. The cause of death was certified as acute butyr-fentanyl, acetyl-fentanyl and cocaine intoxication, and the manner of death was certified as accident. PMID:26683128

    The authors deal with a case of suicidal attempt resulting in a fatal head injury. A young man shot himself with a serially produced mechanical sports crossbow. The young man with a critical intracranial injury, a penetration, was nevertheless capable of basic locomotive activity, as well as of coherent communication with another people present at the scene. The critically injured patient was transported from the scene directly to medical centre where he subsequently underwent a neurologic surgery. On the eight day after the incident he died in the hospital as a result of sustained wounds. During the autopsy, a penetrating arrow-shot wound head injury was certified, occurring in the right and left temple area. Signs of a complex decompressive craniectomy were established too. The shooting channel was generally horizontally oriented, extending from the right to the left side, from behind in a 10 up to 15 degrees angle to the frontal plane, penetrating the brain from the right temple lobe and the frontal lobe, thereby pervading also frontal horns of lateral ventricles, and from the left afflicting the frontal lobe on the left side of the brain. In the course of the shooting channel, brain contusion occurred, accompanied by intraventricular haemorrhage. In addition, a heavy cerebral oedema, multiple secondary malacias, Durett haemorrhages and extensive thrombosis of cerebral sinuses were stated. In the course of police investigation, based mainly on the information given by the wounded man right after he had been found at the scene, it was revealed that another person might have been involved. The forensic autopsy, the investigation of the Police and the subsequent criminalist-ballistics expert investigation, supported by a series of experimental substitutive target shots, didnt, however, decidedly prove that any other culprit had been involved.

  17. Occupational injury fatalities--1994.

    1996-01-01

    Factory workers caught in machinery and construction workers falling or struck by huge beams are images that typically come to mind when considering serious hazards in the workplace. But these types of events account for only a small portion of job-related fatalities each year. Transportation-related fatalities, along with assaults and violent acts during work, made up almost two-thirds of the 6,588 fatal work injuries recorded in 1994. The majority of job-related fatal work events occurred on the streets and highways and in public buildings and in areas such as grocery stores and parking lots. Today the most deadly jobs are found in outdoor occupations such as fishing and timber cutting. In fact, in all 10 jobs studied that have high fatality rates, most workers are affected by severe weather conditions while driving on highways, performing farm chores and working at construction sites. Highway crashes are the primary cause of trucker fatalities; falls are the leading cause of death for roofers, construction laborers and structural metal workers, while tractor rollovers account for a third of farm worker fatalities. Another deadly contributing factor for some workers is homicide, which accounted for 16 percent of job-related fatalities in 1994. Workers most at risk are those who work alone, work late at night and handle varying sums of money. Taxicab drivers are the most susceptible and have a work injury fatality rate nine times higher than the national rate of 5 deaths per 100,000 workers. Others at high risk of homicide include gas station cashiers, grocery store employees and workers in retail eating and drinking establishments. Although the risk of a fatal injury at work varies greatly by occupation and industry, no one is immune. For prevention, workers and employers need to know what jobs are risky, what equipment is dangerous and what activities are hazardous. They also should understand that a fatal incident can happen to anyone.

    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 < 0.10) were detected between microbiologic agents and between agents and pathologic processes. When IHC staining was used, 25/26 (96%) of animals that were positive for bovine viral diarrhea virus (BVDV) were also positive for MH; 12/15 (80 %) of animals that were positive for Histophilus somni (HS) were also positive for MB; and all of the animals that were positive for HS were negative for MH and BVDV. This quantitative pathological study demonstrates that several etiologic agents and pathologic processes are involved in fatal BRD of feedlot cattle. PMID:18512458

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

It is unknown whether adolescents crash less per miles driven or drive less under GDL policies. Methods We used data from the US National Household Travel Survey and Fatality Analysis Reporting System for 1995–1996, 2001–2002, and 2008–2009. We compared adolescents subject to GDL laws with those not, by estimating adjusted incidence rate ratios for being a driver in a crash with a death per person-year (aIRRpy) and per miles driven (aIRRm), and adjusted miles driven ratios (aMR) controlling for changes in rates over time. Results Comparing persons subject to GDL policies with those not, 16-year-olds had fewer fatal crashes per person-year (aIRRpy 0.63, 95% confidence interval [CI] 0.47, 0.91), drove fewer miles (aMR 0.79, 95% CI 0.63, 0.98), and had lower crash rates per miles driven (aIRRm 0.83, 95% CI 0.65, 1.06). For age 17, the aIRRpy was 0.83 (95% CI 0.60, 1.17), the aMR 0.80 (95% CI 0.63, 1.03), and the aIRRm 1.03 (95% CI 0.80, 1.35). For age 18, the aIRRpy was 0.93 (95% CI 0.72, 1.19), the aMR 0.92 (95% CI 0.77, 1.09), and the aIRRm 1.01 (95% CI 0.84, 1.23). Conclusions If these associations are causal, GDL laws reduced crashes per person-year by about one-third among 16-year-olds; half the reduction was due to fewer crashes per miles driven and half to less driving. For ages 17 and 18, there was no evidence of reduced crash rates per miles driven. PMID:24525908

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

    Balamuthia mandrillaris is one of the 4 amebas in fresh water and soil that cause diseases in humans. Granulomatous amebic encephalitis (GAE), caused by B. mandrillaris, is a rare but life-threatening condition. A 4-year-old, previously healthy, Thai girl presented with progressive headache and ataxia for over a month. Neuroimaging studies showed an infiltrative mass at the right cerebellar hemisphere mimicking a malignant cerebellar tumor. The pathological finding after total mass removal revealed severe necrotizing inflammation, with presence of scattered amebic trophozoites. Cerebrospinal fluid (CSF) obtained from lumbar puncture showed evidence of non-specific inflammation without identifiable organisms. A combination of pentamidine, sulfasalazine, fluconazole, and clarithromycin had been initiated promptly before PCR confirmed the diagnosis of Balamuthia amebic encephalitis (BAE). The patient showed initial improvement after the surgery and combined medical treatment, but gradually deteriorated and died of multiple organ failure within 46 days upon admission despite early diagnosis and treatment. In addition to the case, 10 survivors of BAE reported in the PubMed database were briefly reviewed in an attempt to identify the possible factors leading to survival of the patients diagnosed with this rare disease.

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

    A case of near-fatal oseltamivir-resistant seasonal influenza A infection in a previously healthy four-year-old boy is reported. This case highlights three important points for physicians: oseltamivir-resistant influenza A (H1N1) has recently emerged in North America; contrary to previously held beliefs, such strains are capable of causing severe disease in healthy children; and given this change in epidemiology, clinicians caring for children with severe seasonal influenza A infection should consider empiric dual therapy with oseltamivir and amantadine.

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

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

    A boy with metastatic and fatal chondroblastoma is presented. Unlike previously published examples of metastatic chondroblastoma, these metastases developed before any operative manipulation of the primary tumor. The histologic characteristics of the primary, metastatic, and locally recurrent tumors were those of a conventional chondroblastoma. A review of published cases of atypical, aggressive, and malignant chondroblastoma is presented with current follow-up information. Although some metastatic chondroblastomas may result from operative manipulation of the primary tumor and are clinically benign, other histologically benign chondroblastomas exist that are capable of pursuing a malignant course. The authors designate these as malignant chondroblastomas. No histologic criteria exist for the separation of these tumors.

    Fatal familial insomnia (FFI) has been exclusively associated with a pathogenic mutation at codon 178 in the PRNP gene coupled with methionine (Met) at codon 129. We now describe a subject with familial Creutzfeldt-Jakob disease, heterozygous for the pathogenic lysine (Lys) mutation at codon 200 and homozygous for Met at codon 129 of the PRNP gene, who was affected by severe insomnia. At autopsy the patient had significant involvement of the thalamus, as previously described in subjects affected by FFI with the codon 178 mutation. This case demonstrates the wide variability of the clinical expressions in patients with the codon 200 mutation, that may include insomnia and thalamic pathology.

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

    This study was designed to quantify the percent contribution of exposure, risk of collision and fatality rate to the association of age and sex with the mortality rates among cyclists in Spain, and to track the changes in these contributions with time. Data were analyzed for 50,042 cyclists involved in road crashes in Spain from 1993 to 2011, and also for a subset of 13,119 non-infractor cyclists involved in collisions with a vehicle whose driver committed an infraction (used as a proxy sample of all cyclists on the road). We used decomposition and quasi-induced exposure methods to obtain the percent contributions of these three components to the mortality rate ratios for each age and sex group compared to males aged 25-34 years. Death rates increased with age, and the main component of this increase was fatality (around 70%). Among younger cyclists, however, the main component of increased death rates was risk of a collision. Males had higher death rates than females in every age group: this rate increased from 6.4 in the 5-14 year old group to 18.8 in the 65-79 year old group. Exposure, the main component of this increase, ranged between 70% and 90% in all age categories, although the fatality component also contributed to this increase. The contributions of exposure, risk of crash and fatality to cyclist death rates were strongly associated with age and sex. Young male cyclists were a high-risk group because all three components tended to increase their mortality rate. PMID:25658669

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

    The potent cytotoxic drug cyclophosphamide has been used extensively for neoplastic and non-neoplastic diseases. Patients taking this drug may have received or may be receiving pelvic irradiation concurrently. This report describes two patients who developed fatal hemorrhagic cystitis induced by pelvic irradiation and cyclophosphamide therapy. Etiology, incidence, pathologic descriptions, and diagnostic and therapeutic aspects of this entity are described. The incidence and risk of serious, life-threatening bladder hemorrhage from cyclophosphamide therapy is increased by prior or concurrent pelvic irradiation. Alternative cytotoxic, non-urotoxic chemotherapy should be used in these high-risk patients.

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

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

    Co-infection with pathogens that cause acute febrile illness creates a diagnostic challenge as a result of overlapping clinical manifestations. Here, we describe four fatal cases of Leptospira species/dengue virus co-infection in Puerto Rico. Although all patients sought care early, antibiotic administration was delayed for most. Steroids were administered to all patients, in most cases before antibiotics. These cases show the need for clinicians evaluating patients in or recently returned from the tropics with acute febrile illness to consider both dengue and leptospirosis. Furthermore, they illustrate the need for nucleic acid- or antigen-based rapid diagnostic tests to enable timely patient diagnosis and management. In particular, antibiotic therapy should be initiated early for patients with suspected leptospirosis, and steroids should not be administered to patients with suspected dengue. PMID:25092820

    This report describes a case of fatal systemic toxoplasmosis in a 2.5-year-old mixed breed pregnant cat and its kittens. The pregnant cat was presented to the gynecology clinic with symptoms of dystocia. The ultrasound examination revealed the presence of five fetuses in the uterus, three of which were not alive, and consequently a cesarean section was performed. However, the mother cat and the remaining two live kittens died two and ten days after cesarean section, respectively. Pathologically, severe alveolar edema, tachyzoite-like structures in the alveolar macrophages and multifocal necroses in the lungs of mother cat were observed. An intense Toxoplasma gondii immunopositive reaction was observed in the cytoplasms of alveolar macrophages, bronchial and bronchiolar epithelia, necrotic foci in the lungs, and Kupffer cells of the liver. PCR analyses amplified T. gondii DNA in tissue samples of the mother cat and kittens. The present study provides strong evidence for a transplacental transmission of T. gondii infection with deadly outcome for the mother cat, fetuses and kittens. As to the authors' knowledge, this report is the first case of fatal congenital toxoplasmosis in domestic cats in Turkey. PMID:23758036

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

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

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

    The prevalence of drug-associated toxic encephalopathy is unknown, but it is an uncommon condition. Toxic leukoencephalopathy was described associated with heroin consumption, it has been less commonly described with the use of cocaine and there are no reports of its association with consumption pasta base of cocaine (PBC). We report two females aged 31 years and a male aged 19 years, consumers of PBC who developed a fatal toxic leukoencephalopathy. They initiated their disease with severe and persistent headache, sequential focal neurologic deficits and a progressive impairment of consciousness that culminated with their death. Laboratory parameters such as blood count, cerebrospinal fluid analyses or infectious biological indices were normal. MRI showed multifocal lesions in brain white matter of both hemispheres confirming the leukoencephalopathy. There was no response to the use of methylprednisolone. PMID:26757874

    Limited forensic and clinical experience and the lack of confirmatory testing strategies for synthetic cannabinoids (SC) prevent adequate characterization of SC toxicity and the potential impact on public health. A statewide surveillance system identified a fatality involving a 23-year-old man found with a large stab wound to the neck following use of a SC product suspected of containing AM2201. Analytical testing for common SCs, SC metabolites, routine drugs of abuse, and over-the-counter medications was performed on heart blood obtained at autopsy. Additionally, assays were performed on the SC raw material and drug paraphernalia found on the decedent. High concentrations of AM2201 were detected in all samples. AM2201 metabolites were detected in postmortem blood. Other than a trace amount of JWH-073 found in smoke residue, no other substances were detected. Psychiatric complications including self-induced, lethal trauma can occur after the use of SC products.

    Survival time and physical activity following fatal injury are especially important during investigation of homicide cases and the estimation of a victim's survival time and physical activity following a fatal injury from a sharp weapon is a commonly raised issue, particularly at trial. According to the literature, survival time and physical activity after cardiac damage are short-term estimates without high accuracy. We report the homicide case of a young man who died as a result of a left ventricle injury caused by a sharp pointed weapon. This case is based on evidence from a video surveillance camera that recorded the whole scene after the fatal injury: The victim showed an adapted physical activity for 38 s, although the left ventricle incision measured 2 cm. Despite several cases in the literature, it is not possible to correlate precisely the size of the wounds and the acting capability.

    Streptobacillus moniliformis is the primary cause of rat bite fever in North America. Children under 12 years of age are primarily infected, presenting with an acute syndrome of fever, rash, and polyarthritis. Common vectors include rats and mice. Transmission is predominantly from a bite or scratch, but contact with or ingestion of food contaminated with feces or saliva has also been reported. We report a fatal case of S. moniliformis infection in a 14-month-old-boy. At home, the child was exposed to filthy living conditions and the family had pet ferrets. Autopsy revealed a red-pink, mostly confluent rash and a circumscribed area suspicious for a possible bite mark. Cerebrospinal fluid cultures were positive for S. moniliformis. This case highlighted key features, such as the morbiliform rash, but lacked lymphadenopathy or joint manifestations. It is important to consider rat or rodent exposure as a source of infection.

    Meningitis due to Mycoplasma hominis in adults is rarely described, with only three cases having been reported to date. A case of fatal meningitis in a 39-year-old patient after a neurosurgical procedure for a subarachnoid haemorrhage is reported herein. Identification and treatment were significantly delayed because of the rarity of the aetiology and difficulty identifying this organism with the routinely used conventional methods, such as Gram staining and agar growth on standard agar plates. Clinical procedures and the treatment of 'culture-negative' central nervous system infections is a real challenge for clinical microbiologists and clinicians, and M. hominis has to be considered as a potential, although very uncommon, pathogen.

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

    Côte d'Ivoire is an endemic country for yellow fever, but no case was officially notified in recent years. In July 1999, however, one fatal case was reported. A German citizen was infected in the national park of Comoe, in the north eastern area of the country. In order to evaluate the extent of amaril virus circulation and the risk for local people, a virological, entomological and epidemiological investigation was carried out by the ministry of health, the OCCGE, the Côte d'Ivoire Pasteur Institute (IPCI) and the World Health Organisation in the area where the fatal case had been staying. 18 suspected and 24 confirmed mosquito catchers were identified by interview and a blood specimen was collected from each of them. In addition, 159 batches of mosquitoes from which 94 batches of potential vectors were collected; among the suspected cases, 22% were immunised against yellow fever. Serological and virological analyses were made at IPCI and the Paris Pasteur Institute by ELISA technique and isolation on cells cultures and newborn mice. All the suspicious sera and 87.5% of the catchers were positive for IgG anti-amaril virus. One catcher's serum was positive for IgM anti-amaril virus. 11 suspected sera were positive for IgG anti-dengue virus with 1 positive for IgM. 1 strain of amaril virus and 3 strains of Zika virus were isolated from mosquitoes at IPCI and confirmed by CRORA in Dakar. These results indicated that there is a yellow fever and dengue virus are prevalent among the human and vector populations in the study area. Preventive measures must be adopted to protect human beings at risk for amaril infection.

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

    A case of lethal poisoning due to trichlorofluoromethane (FC11) inhalation is described. The fluorocarbon was determined in biological tissues by headspace gas chromatography-mass spectrometry. FC11 was detected in all the examined tissues, with decreasing levels in heart, lung, brain, liver, blood, kidney, and spleen. The highest concentration measured in heart could be related to the mode of toxic action of fluorocarbons postulated by many authors, characterized by the sensitization of the myocardium to the catecholamines producing arrhythmia and cardiac arrest. Nevertheless the aspecific picture of the anatomo-pathological and histological findings does not exclude that the described accidental fatality may have been caused by the combination of direct from toxicity with hypoxemic asphyxiation, due to the saturation of the atmosphere by FC11 in the closed environment in which the intoxication occurred.

  2. Tuberculosis Case Fatality and Other Causes of Death among Multidrug-Resistant Tuberculosis Patients in a High HIV Prevalence Setting, 2000-2008, South Africa

    2016-01-01

    Introduction South Africa has the highest reported rates of multi-drug resistant TB in Africa, typified by poor treatment outcomes, attributable mainly to high default and death rates. Concomitant HIV has become the strongest predictor of death among MDR-TB patients, while anti-retroviral therapy (ART) has dramatically reduced mortality. TB Case fatality rate (CFR) is an indicator that specifically reports on deaths due to TB. Aim The aim of this paper was to investigate causes of death amongst MDR-TB patients, the contribution of conditions other than TB to deaths, and to determine if causes differ between HIV-uninfected patients, HIV-infected patients receiving ART and those without ART. Methods We carried out a retrospective review of data captured from the register of the MDR-TB programme of the North West Province, South Africa. We included 671 patients treated between 2000–2008; 59% of the cohort was HIV-infected and 33% had received ART during MDR treatment. The register contained data on treatment outcomes and causes of death. Results Treatment outcomes between HIV-uninfected cases, HIV-infected cases receiving ART and HIV-infected without ART differed significantly (p<0.000). The cohort death rate was 24%, 13% for HIV-uninfected cases and 31% for HIV-infected cases. TB caused most of the deaths, resulting in a cohort CFR of 15%, 9% for HIV-uninfected cases and 20% for HIV-infected cases. Cohort mortality rate due to other conditions was 2%. AIDS-conditions rather than TB caused significantly more deaths among HIV-infected cases receiving ART than those not (p = 0.02). Conclusions The deaths among HIV-infected individuals contribute substantially to the high death rate. ART co-therapy protected HIV-infected cases from death due to TB and AIDS-conditions. Mechanisms need to be in place to ensure that HIV-infected individuals are retained in care upon completion of their MDR-TB treatment. PMID:26950554

    This is a report of postmortem false-positive reactivity using an enzyme-multiplied urine phencyclidine (PCP) immunoassay (EMIT II+) due to a single-agent fatal tramadol overdose. An autopsy of a 42-year-old male who died alone at home revealed no identifiable lethal anatomic abnormalities, thus leading to toxicologic analysis. Femoral blood was obtained for drug testing by high-performance liquid chromatography (HPLC) and showed a tramadol level of 14.0 mg/L, 2 orders of magnitude greater than the therapeutic range (0.1 to 0.3 mg/L). Urine was also obtained and EMIT II+ immunoassay revealed positivity for PCP at 88 mAU/min. However, confirmatory testing by HPLC failed to identify PCP in either the urine or serum. To verify the suspicion that this was a false-positive PCP result, stock solutions of tramadol and its major metabolite (O-desmethyltramadol) at concentrations of 100 mg/L in 10% methanol/H2O were compared with a blank solution (10% methanol/H2O) for EMIT II+ PCP reactivity and demonstrated reactivities of 44 mAU/min and 27 mAU/min, respectively. While these individual results were below the cutoff reactivity for a positive EMIT II+ PCP result (ca. 85 mAU/min), they were much more reactive than the blank calibrator (set at 0 mAU/min). Therefore, we conclude that the immunoreactivity of tramadol and its metabolites in aggregate is responsible for the PCP immunoassay interference and false-positive result.

  4. Traffic fatalities and economic growth.

    PubMed

    Kopits, Elizabeth; Cropper, Maureen

    2005-01-01

    This paper examines the relationship between traffic fatality risk and per capita income and uses it to forecast traffic fatalities by geographic region. Equations for the road death rate (fatalities/population) and its components--the rate of motorization (vehicles/population) and fatalities per vehicle (F/V)--are estimated using panel data from 1963 to 1999 for 88 countries. The natural logarithm of F/P, V/P, and F/V are expressed as spline (piecewise linear) functions of the logarithm of real per capita GDP (measured in 1985 international prices). Region-specific time trends during the period 1963-1999 are modeled in linear and log-linear form. These models are used to project traffic fatalities and the stock of motor vehicles to 2020. The per capita income at which traffic fatality risk (fatalities/population) begins to decline is 8600 US dollars (1985 international dollars) when separate time trends are used for each geographic region. This turning point is driven by the rate of decline in fatalities/vehicles as income rises since vehicles/population, while increasing with income at a decreasing rate, never declines with economic growth. Projections of future traffic fatalities suggest that the global road death toll will grow by approximately 66% over the next twenty years. This number, however, reflects divergent rates of change in different parts of the world: a decline in fatalities in high-income countries of approximately 28% versus an increase in fatalities of almost 92% in China and 147% in India. The road death rate is projected to rise to approximately 2 per 10,000 persons in developing countries by 2020, while it will fall to less than 1 per 10,000 in high-income countries.

    While it is known that diesel fuel combustion engines produce much lower concentrations of carbon monoxide (CO) than gasoline engines, these emissions could certainly generate lethal ambient concentrations given a sufficient amount of time in an enclosed space and under suitable environmental conditions. The authors report a case of CO poisoning which was initially referred for autopsy as a presumed natural death of a truck driver found in the secure cab of a running diesel tractor trailer truck. Completion of the preliminary investigation ascribed death to complications of ischemic heart disease (IHD), pending toxicological analysis that included quantification of CO. When the toxicology results showed lethal blood COHbg, the cause of death was re-certified as CO intoxication secondary to inhalation of (diesel) vehicular exhaust fumes. Because of the unique source of fatal CO intoxication in this case, the contributory IHD and the possible contaminants in the putrefied blood, a 10-year retrospective review was conducted on all nonfire related CO deaths autopsied (n = 94) at the Office of the Chief Medical Examiner in Louisville, KY from 1994 to 2003. For validation of the COHbg detection method used by the Kentucky Office of Forensic Toxicology (KYOFT), blood samples from these cases along with controls were submitted to three laboratories using various analytical methods yielding no statistically significant differences. Lastly, an extensive literature review produced no scientifically reported cases of fatal CO poisoning attributed to diesel fuel exhaust.

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

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

    There has been an increase in cycling in Australia. This means that more cyclists are at risk of injuries, which account for a proportion of transport-related fatalities. In this study, all cyclist fatalities from 2002 to 2013 in South Australia where post-mortem examinations were performed were investigated. There were 42 deaths representing 3% of the total road fatalities over the same time. Of this total number of cases, 13 deaths (31%) involved collapse (mostly natural causes from an underlying medical condition) and 29 (69%) resulted from trauma. There were no cases of hyperthermia. Of the decedents 95% were male, and the mean age at death was 47 years. Fatal incidents were more likely to occur during April and November, and on a Monday. However, statistical analysis was not possible due to the small number of cases. Fatalities (traumatic and collapse) predominantly occurred whilst the cyclist was riding (86%). The majority of riding fatalities were as a result of collision with vehicles (81%). Drugs (including alcohol) were detected in two (15%) of the 13 cases of the collapses, and in seven (26%) of the 27 trauma cases tested. In trauma cases, death was most often due to multiple injuries. The most frequent area for injury was the head (found in 90% of traumatic deaths). Despite the increasing numbers of cyclists on South Australian roads over the last decade, death rates have trended downwards suggesting that road safety campaigns and the provision of more dedicated bicycle lanes have had a positive outcome.

    Tuberculous meningitis (TBM) is a preventable and curable common health problem among African adults. Poor nutrition, poverty, household crowding, drug resistant tuberculosis (TB) strains, AIDS, and malfunctioning TB control programs are important risk factors. We conducted a systematic review and meta-analysis of published literature reporting case-fatalities of TBM among adults in African countries from 1970 till date. A PubMed search identified relevant papers. Employed terms include 'adult tuberculous meningitis' AND 'tuberculosis Africa'. PRISMA review guidelines were applied. Adult TBM case-fatalities, odds ratio (OR), relative risk (RR), forest-plot meta-analysis for weighted OR and RR, funnel plots, L'Abbé plots, meta-regressed bubble plots, and inter-study homogeneity were computed. Among 15 studies included, adult TBM occurred in up to 28 % of all meningitis forms with case-fatality of 60 % (inverse-variance weighted 54 %). Fixed-effect meta-analysis revealed weighted OR and RR of adult TBM fatalities to be 4.37 (95 % CI 3.92, 4.88) and 2.53 (95 % CI 2.38, 2.69), respectively. Inter-study homogeneity was reliable, regional representativeness was adequate allowing generalizability, and funnel-plots behaved symmetrically with insignificant inconsistency. All cases were initiated with anti-TB medication, while some had 'breakthrough' TBM. In Africa, adult TBM has a significant public health importance with a very high fatality which has remained stagnant for the past half-century. This reflects ongoing low quality of medical care at facilities where lengthy referrals end up. Community-based studies can reveal higher unaccounted morbidity, accrued disability, and larger mortality. Improving access points for early TB management at community-level, developing health infra-structure for comprehensive case management at facility-level, and poverty reduction can help combat this multi-faceted problem--whose reduction can in return help fight poverty.

    The infantile skull is malleable, and its sutures are tightly adhering to the underlying dura and venous sinus. These characteristics, in association with the small amount of total blood volume, can result in a specific fatal type of skull fracture, which is unique to infancy. The authors report a case of this injury, and stress the need to pay attention to the possibility of massive bleeding during operation in infants. A 23-month-old female baby presented with semicomatose mentality after sustaining injuries by falling from a second-floor. Plain skull films showed bi-frontal skull fracture crossing the midline. Computed tomography revealed an acute subdural hematoma along the right convexity with severe brain edema. In the emergency operation, the scalp incision exposed massive bleeding from the fracture site. The bleeding was identified as arising from the lacerated and widely separated sagittal sinus beneath the fracture. The patient entered hypovolemic shock immediately after the scalp incision, and died from severe brain edema two days after the trauma and surgery. This case implies that special care should be paid during the operation of patients that have skull fracture overlying the venous sinus, especially when the fracture line is separated. PMID:27169046

    A 71-year-old Japanese woman presented to the Department of Neurosurgery of Keio University School of Medicine (Tokyo, Japan) with a leiomyosarcoma originating in the infratemporal fossa and an 85-mm metastasis to the right lung. Since the pulmonary lesion was associated with risk of airway obstruction, radiation therapy (50 Gy/20 fractions) was administered to the patient, which resulted in remarkable tumor shrinkage. Subsequently, the patient was administered 800 mg/day pazopanib for 10 weeks, which resulted in further reduction in tumor size. However, the patient succumbed to a massive hemorrhage of sudden onset. Three possible explanations for the fatal hemorrhage are: i) adverse reaction to pazopanib; ii) side effects of radiation; and iii) remarkable tumor shrinkage. As a result, it may be proposed that the synergic effects of the aforementioned hypotheses may have been responsible for the bleeding observed in the present case. Therefore, clinicians should be alert to the possibility of this adverse event. In the present study, the first case of mortality due to massive hemorrhage following remarkable tumor shrinkage induced by radiation therapy and subsequent pazopanib treatment is reported.

    There are 2 main types of meningoencephalitis caused by free-living amoebae. The first is a well-defined acutely fatal disease resembling fulminating bacterial meningitis. It is caused by the single species Naegleria fowleri. The second is a more poorly defined disease that runs a subacute or chronic course and is characterized by focal granulomatous lesions in the brain. The causative organisms are probably Acanthamoeba sp. in most cases, but it is possible that other genera may be involved. The first case of the subacute form of the disease to be recognized in Australia is described. A 2 1/2-yr-old, previously well girl presented with ataxia and lower motor neurone paralyses. The cerebrospinal fluid was pleocytic and she was thought to be suffering from a relatively minor viral brain-stem encephalitis. Her symptoms persisted in a peculiarly fluctuating way for 30 d when she suddenly collapsed and died from an intracranial haemorrhage. Necropsy showed focal granulomatous lesions associated with necrotizing vasculitis in the basal regions of the brain. The lesions contained well preserved free-living amoebae which were morphologically different from N. fowleri and most closely resembled Acanthamoeba sp. The ultrastructure of the organisms was particularly well preserved and is described in some detail. Immunohistological studies also excluded N. fowleri but were inconclusive for Acanthamoeba or other genera of free-living amoebae. Difficulties with the diagnosis and treatment of this disease are discussed and some practical suggestions are made. PMID:6261208

    Henoch-Schönlein purpura (HSP) is a rather common disease characterized by systemic hypersensitivity vasculitis in the skin and other visceral organs. It has a favorable prognosis unless it is complicated by severe glomerular disease. We report a distinctive fatal case of systemic vasculitis combined with HSP and polyarteritis nodosa (PN) in a 56-year-old man who died of progressive renal failure one month after the onset of the disease. He complained of arthralgia, purpura of both lower extremities, nasal bleeding and tarry stool, and acute renal failure was noted at the time of admission to hospital. A skin biopsy from the purpura lesion exhibited leucocytoclastic vasculitis with IgA deposition, and HSP was considered. However, renal failure progressed rapidly and subsequently was complicated by acute myocardial infarction. Postmortem examination revealed PN type necrotizing vasculitis in the kidneys, heart and mesentery resulting in acute multiple infarctions of these organs. We think the current case was a polyangitis overlap syndrome. It is important to suspect the polyangitis overlap syndrome positively when progressive acute renal failure is seen in a patient with HSP and to begin appropriate therapy immediately.

One of the most serious, although one of the rarest is perforation of gastrointestinal tract. In this case report we describe a 52-year old male, with disseminated melanoma with unknown starting point, treated with anti- CTLA4 monoclonal antibody. After 3rd dose of drug administration, bloody diarrhea and acute abdominal pain occurred as a symptom of gastrointestinal perforation. A single perforation was sutured during laparotomy. Symptoms of acute abdomen returned after 10 days. Pus-faecalperitonitis, symptoms of necro-hemorrhagic colitis and multilocal perforation of the colon were found during relaparotomy. Pancolectomy with end ileostomy was performed. Few hours since relaparotomy pacient died due to multiple organ failure. The purpose of this case report is to draw attention to a risk of multilocal colon perforation in patient treated with ipilumumab.

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

    During the years 2004-2006, seven divers, who had deadly accidents, underwent post-mortem examination at the Institute of Legal Medicine of the University of Munich. The cause of death in all divers was drowning with typical pathomorphological findings. This should be regarded as separated to the triggering reason for drowning. The trigger for accident was established in four of seven cases by technical analysis and police investigation. High risk-taking, lack of technical service, and deficiency of dive equipment care were main reasons for death. We present two of these cases which showed several problems occurring concurrently. Autopsy always is necessary to look for indices for application of force or to exclude competitive reasons for death. PMID:18706775

    Acute interstitial pneumonitis (AIP), also known as Hamman-Rich syndrome, is a distinct type of idiopathic interstitial pneumonia affecting patients of both genders without pre-existing lung diseases. We describe the case of a fulminant form of AIP and discuss the pathophysiological mechanisms of AIP with reference to the histological pattern. A 15-year-previously-healthy male boy presented to the Hospital with a 6-day history of malaise, fever and cough. The clinical prodromes were followed by the acute onset of increasing shortness of breath rapidly progressing in acute respiratory failure. Chest X-ray demonstrated bilateral diffuse airspace opacification; the high resolution CT confirmed the presence of bilateral, symmetric diffuse ground-glass attenuation. The patient was admitted to the intensive care unit, but died after few hours. An autopsy was performed within 24h. The histological examination of lung specimens showed a pattern of diffuse alveolar damage. immunohistochemical, microbiological and toxicological tests were also carried out. The clinical presentation, the histological findings and the exclusion of infective, traumatic, toxic and metabolic causes of acute respiratory distress syndrome (ARDS) allowed us to conclude that the boy was affected by AIP. In conclusion, AIP is a diagnosis of exclusion. It has a mortality rate ranging about 50%, despite mechanical ventilation. In fatal cases of AIP diagnosis can be based on clinical presentation, radiological, histological and microbiological findings and can be further confirmed by immunohistochemical analysis.

    The present study aimed to investigate the impact of postoperative antiviral treatment on tumor recurrence, fatalities and survival of patients with chronic hepatitis B virus (HBV) infection-related primary hepatocellular carcinoma (HCC). A systematic meta-analysis was performed. All the studies comparing nucleos(t)ide analogues (NAs) versus placebo or no treatment were considered. The results were expressed as relative ratio (RR) for 1-, 3- and 5-year recurrence-free survival (RFS) and overall survival (OS), recurrence HCC and fatalities with 95% confidence intervals (CI) using STATA 11.0. In total, 15 trials with 7,619 patients were included. There were significant improvements for 1-, 3- and 5-year RFS (RR, 1.09; P=0.003; RR, 1.202; P<0.001; and RR, 1.219; P=0.02; respectively) and in 3- and 5-year OS (RR, 1.087, P=0.006; and RR, 1.186; P<0.001) in the NAs group compared with the control group. Sensitivity analyses confirmed the robustness of the results. In addition, the significantly high rate of recurrence HCC and fatalities existed in the control group (RR, 1.301; P=0.002; and RR, 1.816, P<0.001). One study was for an entecavir (ETV)-treated group compared with an adefovir (ADV)-treated group and lamivudine (LAM)-treated group. The 3-year disease-free survival rate for the ETV group was significantly better compared with the ADV and LAM groups [hazard ratio (HR), 0.810; P=0.049; and HR, 0.737; P=0.007]. The present study demonstrated the beneficial effects of NAs therapy following curative treatment of HBV-related HCC. ETV may be the superior choice compared to ADV or LAM for the antiviral treatment. PMID:26807227

    Herein we present two cases of hypereosinophilic syndrome with a unique clinical presentation. One patient showed severe systemic thrombosis with splenic rupture and the other patient showed finger gangrene with various systemic symptoms. Both patients were examined histologically, and several characteristics were noted. First, fresh or organized thrombosis with marked eosinophilic infiltration was observed in the cavity and walls of the thrombosed vessels. Second, many eosinophils showed degranulation and were positive for eosinophilic cationic protein on immunohistological examination. Third, the structures of thrombosed vessels were well preserved, which is not observed in systemic vasculitis. These patients exhibited no neoplastic features and were treated with prednisolone with excellent therapeutic results.

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

    JC virus (JCV) is the etiologic agent of progressive multifocal leukoencephalopathy, JCV granule cell neuronopathy and JCV encephalopathy. Whether JCV can also cause meningitis, has not yet been demonstrated. We report a case of aseptic meningitis resulting in symptomatic hydrocephalus in an HIV-seronegative patient. Brain imaging showed enlargement of ventricles but no parenchymal lesion. She had a very high JC viral load in the CSF and developed progressive cognitive dysfunction despite ventricular drainage. She was diagnosed with pancytopenia and passed away after 5 ½ months. Post-mortem exam revealed productive JCV infection of leptomeningeal and choroid plexus cells, and limited parenchymal involvement. Sequencing of JCV CSF strain showed an archetype-like regulatory region. Further studies of the role of JCV in aseptic meningitis and in idiopathic hydrocephalus are warranted. PMID:24895208

    Sudden death during or after sauna bathing is a rare event. When occurring accidentally, it is often caused or contributed by consumption of ethanol. To accidentally burn to death because of hot air is highly uncommon without some contributing factor that lowers the person's consciousness. Hot air burns have been reported to develop in 20 to 60 minutes. We present a case of sudden death of a healthy man with rare and extensive hot air burns that developed in less than 10 minutes in the sauna. Ethanol was not a contributing factor. Substantial injuries were found at the autopsy, both external and internal, for instance, small hemorrhages in the stomach mucosa, indicating a heavy antemortem stress reaction. The most probable reason for the extensive scalds was concluded to be, apart from the high temperature, the high degree of relative humidity in the sauna.

    Iatrogenic vascular injury during lumbar disk surgery, although rare, is a serious complication, and when it does occur, can be sudden and life-threatening. The risk of injury to the pelvic vessels intra-operatively can be explained by the close proximity of the retroperitoneal vessels to the vertebral column therefore causing injury to the anterior longitudinal ligament, which can give access to the retroperitoneal space. If signs of circulatory instability are noted during lumbar disk surgery, early diagnosis of vascular injury and urgent transperitoneal surgery or emergency stenting can save the patient's life. Here, is presented the case of a 52-year-old man who underwent an elective lumbar discectomy for a rightward disk herniation in the L4-L5 intervertebral space and died 12h after the operation for a hemorrhagic shock due to a severe intra-abdominal hemorrhage following iatrogenic left common iliac artery and vein perforation during lumbar discectomy.

    A 62-year-old woman treated with several courses of corticosteroids for an undifferentiated rash came to the emergency department with progressively worsening cutaneous signs and symptoms and generalized weakness. She had scabies, and despite treatment continued to decompensate. Repeat skin biopsies revealed disseminated herpes simplex virus infection, and results of blood cultures were consistent with infection by methicillin-resistant Staphylococcus aureus. Despite antiviral and antimicrobial therapy, sepsis and multiorgan failure developed, and the patient died. This case illustrates the complications of the rare entity eczema herpeticum, which occurs most often in immunocompromised patients and is associated with a high mortality. Maintaining a high index of suspicion for this disease in decompensating patients with an unidentified rash is essential to avoid catastrophic outcomes. PMID:27369040

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

    Objectives: The objectives of this study were to analyze deaths after gestational trophoblastic neoplasia and to determine the factors of treatment failure. Methods: This is a retrospective study in Aristide Le Dantec teaching Hospital in Dakar, Senegal, between 1 January 2006 and 31 December 2014. We took into account socio-epidemiological characteristics of patients, initial diagnosis, time between uterine evacuation and admission, time to onset of gestational trophoblastic neoplasia (GTN), treatment received (deadlines, protocols), difficulties experienced in the diagnosis and the initiation of treatment and survival. Results: In total, 1044 patients were admitted during the study period; 164 cases of GTN were diagnosed (15.7%); and 21 deaths occurred leading to a specific lethality of 12.8%. The average age was 30 years. Almost all patients (n = 18; 85.7%) had low income or no income. Eight out of 21 patients (38.1%) were seen in our department after GTN onset. The mean time to onset of GTN of all patients was 22.1 weeks. For 66.6%, histology was not available; the diagnosis of hydatidiform mole was made on the clinical history and sonographic features and GTN on human chorionic gonadotrophin (hCG) evolution and ultrasound findings. None of the patients had regular chemotherapy due to financial reasons. Patients who died within 3 months after diagnosis had metastatic tumors (7 of 21). All these women had resistance to treatment or progressed after three courses of chemotherapy. Ten of the 12 women with high-risk GTN were not treated with multi-agent chemotherapy (EMA-CO) for purely financial reasons. Conclusion and Global Health Implications: The high incidence and mortality require a profound reorganization of our health system and a high awareness of practitioners to refer to time or to declare all suspected cases of hydatidiform mole or gestational trophoblastic neoplasia.

    A 67-year-old male was admitted to our hospital because of watery diarrhea and pre-shock status at 10:30 am on March 20, 1995. He had travelled to Bali Island in Indonesia from March 13 to March 18, 1995. On admission, his systolic blood pressure was 60 mmHg and body temperature was 35.2 degrees C. His skin was very dry. Laboratory tests showed that s-Cr was 6.3 mg/dl and CPK was 5620 IU/l. A massive fluid transfusion was given immediately and then his blood pressure rose to 158/92 about two hours after admission. However, he developed a high grade fever and systemic cyanosis in the evening of the first hospital day and died at 0:20 am on March 21st. Salmonella Weltevreden was detected in the fecal and blood cultures obtained on admission. We considered that his acute renal failure was attributable to rhabdomyolysis due to dehydration and that the cause of death was probably septic shock. The patient had a previous history of cholecystectomy ten years ago and also suffered from hypertension, but his general condition was not so bad before this episode. Therefore, we were surprised that his illness became so severe. This case emphasizes that Salmonella enteritis may occasionally be a serious and lethal disease.

    Obstruction of the thoracic duct may lead to accumulation of a lymphatic fluid rich in triglycerides named chyle. When chyle accumulates in the pleural cavity, it becomes a chylothorax. Malignancy, particularly lymphoma, is the most common cause of chylothorax; however, any pathology leading to obstruction or destruction of the thoracic duct can lead to a chylothorax. This particular case investigates an incidence of chylothorax in sarcoidosis. A 54-year-old African American woman with a medical history of sarcoidosis, congestive heart failure, and smoking presented to the emergency department with complaints of bilateral foot swelling and exertional shortness of breath 3 days in duration. Physical examination was positive for bilateral crepitations with decreased air entry, abdominal ascites, and bilateral 2+ pitting edema. Both chest X-ray and chest CT were positive for stable bilateral pleural effusions (when compared to imaging done 3 years previously), and thoracocentesis and paracentesis were positive for chylous fluid accumulation. Chylothorax was diagnosed, and based on the previous medical history, the lymphadenopathy of sarcoidosis was determined to cause the occlusion of the thoracic duct. Lymphoscintigraphy and surgical intervention were advised; however, the family decided on conservative management and the patient expired intubated in the ICU. Chylothorax is a rare manifestation of sarcoidosis and high index of suspicion should be there to diagnose this, as there is high morbidity and mortality associated with it. PMID:26333861

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

    Neurological infections due to rapidly growing mycobacteria (RGM) have rarely been reported. We recently investigated two unrelated immunocompetent patients, one with community-acquired lymphocytic meningitis and the other with cerebral thrombophlebitis. Mycobacterium mucogenicum was isolated in pure culture and detected by PCR sequencing of cerebrospinal fluid samples. Both patients eventually died. The two isolates exhibited an overlapping antimicrobial susceptibility pattern. They were susceptible in vitro to tetracyclines, macrolides, quinolones, amikacin, imipenem, cefoxitin, and trimethoprim-sulfamethoxazole and resistant to ceftriaxone. They shared 100% 16S rRNA gene sequence similarity with M. mucogenicum ATCC 49650T over 1,482 bp. Their partial rpoB sequences shared 97.8% and 98.1% similarity with M. mucogenicum ATCC 49650T, suggesting that the two isolates were representative of two sequevars of M. mucogenicum species. This case report should make clinicians aware that M. mucogenicum, an RGM frequently isolated from tap water or from respiratory specimens and mostly without clinical significance, can even be encountered in the central nervous system of immunocompetent patients.

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

    This report describes a case of yellow fever vaccine-associated viscerotropic disease (YEL-AVD) that occurred after vaccination in a 22-year-old female. Our patient presented with a clinical syndrome of fever, headache, nausea, and vomiting, which quickly progressed to multiorgan failure and ultimately death on hospital day 4. YEL-AVD is an extremely rare condition reported only a few times in the literature. The yellow fever vaccine is a known stimulus of systemic inflammation in the body. A mild subclinical viremia develops, which results in a persistent and robust T-helper-cell-dependent antibody response with long-lasting immune protection. The very rare patient may have an aberrant response to the 17D vaccine strain, causing the multiple organ system failure seen in YEL-AVD. Predisposing host factors that contribute to YEL-AVD are not yet known. Treatment for YEL-AVD is supportive. To the authors' knowledge, this patient was the first to have YEL-AVD as a result of standard US military vaccination protocols.

    A 41-year-old man was accidentally exposed to carbon monoxide (CO) gas and found in a state of cardiopulmonary arrest while he took bath. After admission, he was resuscitated and underwent artificial ventilation in a comatose state and died about 19h later. Computed tomography (CT) examination disclosed bilateral low density area in the basal ganglia and the thalamus, a well-known finding in the CO intoxication. Necropsy, histological examination, DNA ladder assay gave the first line of evidence for the presence of apoptosis as well as necrosis in the human case of CO intoxication. TdT-mediated dUTP-biotin nick-end labeling (TUNEL) positive apoptotic cells were more predominant in the CA2 area than in CA1 area. There is general co-relation between the ratio of TUNEL-positive cells and the DNA laddering on the agarose gel. Basal ganglia and thalamus, which showed bilateral low density area in CT, were revealed to be severe edema. The two types of cell death occurred in the cortex, basal ganglia, hippocampus, thalamus, and cerebellum. Hypoxia caused by CO-hemoglobin formation alone cannot explain the phenomena.

    The authors report the case of a man who suffered from progressive, disseminated posttraumatic dural arteriovenous fistulas (DAVFs) resulting in death, despite aggressive endovascular, surgical, and radiosurgical treatment. This 31-year-old man was struck on the head while playing basketball. Two weeks later a soft, pulsatile mass developed at his vertex, and the man began to experience pulsatile tinnitus and progressive headaches. Magnetic resonance imaging and subsequent angiography revealed multiple AVFs in the scalp, calvaria, and dura, with drainage into the superior sagittal sinus. The patient was treated initially with transarterial embolization in five stages, followed by vertex craniotomy and surgical resection of the AVFs. However, multiple additional DAVFs developed over the bilateral convexities, the falx, and the tentorium. Subsequent treatment entailed 15 stages of transarterial embolization; seven stages of transvenous embolization, including complete occlusion of the sagittal sinus and partial occlusion of the straight sinus; three stages of stereotactic radiosurgery; and a second craniotomy with aggressive disconnection of the DAVFs. Unfortunately, the fistulas continued to progress, resulting in diffuse venous hypertension, multiple intracerebral hemorrhages in both hemispheres, and, ultimately, death nearly 5 years after the initial trauma. Endovascular, surgical, and radiosurgical treatments are successful in curing most patients with DAVFs. The failure of multimodal therapy and the fulminant progression and disseminated nature of this patient's disease are unique.

    Methoxetamine (MXE) is a psychoactive substance distributed mostly via the Internet and is not liable to legal regulation in Poland. MXE has a toxicity profile similar to that of ketamine but longer-lasting effects. The paper describes a case of acute poisoning that resulted from recreational use of MXE and amphetamine and ended in death. In mid-July 2012, a 31-year old man was admitted to the clinical toxicology unit in Gdańsk because of poisoning with an unknown psychoactive substance. The patient was transported to the emergency department (ED) at 5:15 a.m. in a very poor general condition, in a deep coma, with acute respiratory failure, hyperthermia (> 39°C) and generalized seizures. Laboratory tests showed marked leukocytosis, signs of massive rhabdomyolysis, hepatic failure and beginning of acute renal failure. Despite intensive therapy, the patient died 4 weeks after the poisoning in the course of multi-organ dysfunction syndrome. Chemical and toxicological studies of serum and urine samples collected on the poisoning day at 1:40 p.m. confirmed that amphetamine and MXE had been taken earlier that day. Concentration of amphetamine in the serum (0.06 μg/ml) was within the non-toxic range, while MXE (0.32 μg/ml) was within the toxic range of concentrations. Amphetamine was also detected in the patient's hair, which suggested a possibility of its use within the last dozen weeks or so. The serious clinical course of intoxication and co-existence of amphetamine and MXE in the patient's blood and urine suggest the possibility of adverse interactions between them.

    We present in this case report a validated method for accurate quantitative analysis of 3-methoxy phencyclidine (3-MeO-PCP) to determine postmortem blood concentrations of this PCP analog. A 29-year-old male with a history of illicit drug use was found unresponsive in his bed with a bag of white powder next to him. Resuscitation efforts were unsuccessful and the individual was pronounced dead 9 minutes after arrival to the hospital. Initial ELISA screening suggested the presence of PCP in the decedent's blood. However, confirmatory testing revealed no detectable PCP. Instead, a large peak corresponding to a m/z 274.218 species with retention time similar to PCP was present on a LC-TOF-MS drug screen, suggesting a possible PCP analog. This mass corresponds specifically to a methoxy-PCP analog, several of which are available for purchase online. Standards for 3-MeO-PCP and 4-MeO-PCP were obtained and injected on the same instrument. Although the 3- and 4-MeO-PCP analogs have identical masses and retention times, they are still distinguishable through their mass spectra. The peak from the decedent's sample matched both the mass spectrum and the retention time of 3-MeO-PCP. A quantitative LC-MS-MS method was subsequently developed and validated for casework. Analysis using this method revealed a concentration of 139 ± 41 µg/L 3-MeO-PCP in the decedent's blood. Diphenhydramine (4.1 ± 0.7 mg/L), marijuana metabolite (presumptive positive, confirmation not performed) and a small amount of amphetamine (<0.10 mg/L) were also found in the decedent's blood. The cause of death was determined to be combined 3-MeO-PCP, diphenhydramine and amphetamine toxicity. The manner of death was certified as an accident. PMID:27339479

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

    Hypersensitivity reactions are a classic side effect of cetuximab. We report the cases of three patients who developed life-threatening hypersensitivity to cetuximab, which could have been predicted by assessing the concentration of serum anticetuximab immunoglobulin (Ig)E. The anticetuximab IgE concentration could be an interesting test to predict which patients are at risk of experiencing severe hypersensitivity reactions to cetuximab.

    We report here a fatal intoxication case involving ammonium vanadate. A 24-year-old woman was admitted to the Emergency Department for abdominal pain, nausea, vomiting, multiple daily diarrheas, hypoglycaemia (0.2g/L) and severe acute renal failure with glomerular filtration rate estimated at 21 ml/min. This patient had taken an undetermined amount of ammonium vanadate 12h after ingesting. She died next morning in the context of respiratory distress despite intensive care and oxygen therapy. The autopsy revealed widespread asphyxia syndrome and erosive gastritis. Determination of vanadium concentration in blood was carried out by means of mass spectrometer (ICP-MS) using rhodium ((103)Rh) as the internal standard. The vanadium concentration was 6.22 mg/L, corresponding to 6000 times higher than normal concentration in the general population. The latency and the brutality of clinical picture degradation seem to be in consideration of systemic poisoning by vanadium leading to inhibition of the cellular respiratory process.

    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.

    The flaviviruses of major medical importance in South American countries are yellow fever, dengue, Saint Louis encephalitis, West Nile and Rocio viruses. Rocio virus (ROCV) has been responsible for epidemics of severe encephalitis in Brazil with a case-fatality rate of 10 % and development of sequelae in 20 % of the survivors. We have sequenced and characterized the entire genome of ROCV for the first time, by determining the general traits of the open reading frame and the characteristics of viral genes including the potential cleavage sites, conserved or unique motifs, cysteine residues and potential glycosylation sites. The conserved sequences in the 3'-non-coding region were identified, and the predicted secondary structures during cyclization between 5'- and 3'-non-coding regions were studied. Multiple protein and phylogenetic analyses based on antigenically important and phylogenetically informative genes confirmed a close relationship between ROCV and Ilheus virus (ILHV), together constituting a unique and distinct phylogenetic subgroup as well as the genetic relationship of ROCV with several members of the Japanese encephalitis group. Although ROCV is phylogenetically related to ILHV, our study shows that it is still a virus distinct from the latter virus. This is the first flavivirus uniquely indigenous to Brazil that has been sequenced completely and the genome characterized. The data should be useful for further studies at the molecular level, including construction of infectious clone, identification of gene function, improved disease surveillance based on molecular diagnostic tools and vaccine development.

    Introduction Blood-stream infection (BSI) is one of the principle determinants of the morbidity and mortality associated with advanced HIV infection, especially in sub-Saharan Africa. Over the last 10 years, there has been rapid roll-out of anti-retroviral therapy (ART) and cotrimoxazole prophylactic therapy (CPT) in many high HIV prevalence African countries. Methods A prospective cohort of adults with suspected BSI presenting to Queen's Hospital, Malawi was recruited between 2009 and 2010 to describe causes of and outcomes from BSI. Comparison was made with a cohort pre-dating ART roll-out to investigate whether and how ART and CPT have affected BSI. Malawian census and Ministry of Health ART data were used to estimate minimum incidence of BSI in Blantyre district. Results 2,007 patients were recruited, 90% were HIV infected. Since 1997/8, culture-confirmed BSI has fallen from 16% of suspected cases to 10% (p<0.001) and case fatality rate from confirmed BSI has fallen from 40% to 14% (p<0.001). Minimum incidence of BSI was estimated at 0.03/1000 years in HIV uninfected vs. 2.16/1000 years in HIV infected adults. Compared to HIV seronegative patients, the estimated incidence rate-ratio for BSI was 80 (95% CI:46–139) in HIV-infected/untreated adults, 568 (95% CI:302–1069) during the first 3 months of ART and 30 (95% CI:16–59) after 3 months of ART. Conclusions Following ART roll-out, the incidence of BSI has fallen and clinical outcomes have improved markedly. Nonetheless, BSI incidence remains high in the first 3 months of ART despite CPT. Further interventions to reduce BSI-associated mortality in the first 3 months of ART require urgent evaluation. PMID:24643091

    2011-03-20

    Fluoride, of all inorganic substances, is among the least likely to be identified by a routine toxicological analysis. Acute poisonings with salts of hydrofluoric or fluorosilicic acid, however, although relatively uncommon, may occur. Some fluorosilicates, salts of fluorosilicic acid (e.g. Al, Zn, Pb, Mg) are used as stone consolidants, others (e.g. sodium fluorosilicate)--in the production of enamel and milk glass, or as insecticide. In this paper, two fatal cases of poisonings are presented: a suicide involving sodium fluorosilicate of a 39-year-old male who died in his flat, without hospitalization, and an accidental ingestion of zinc fluorosilicate solution (probably due to mistaking it for mineral water) by a 38-year-old male at his workplace (building), who died about 3h after ingestion of the liquid, in spite of intensive care at hospitals. Post-mortem samples were examined by the use of the spectrophotometric method with lanthanum nitrate and alizarin complexone for fluorine (after isolation of fluoride compounds by the microdiffusion method) and using a flame atomic absorption spectrometry method for zinc (after mineralization of biological material by sulfuric and nitric acids). In the first case, the results were: blood--130 μg F/ml, stomach--1150 μg F/g, small intestine content --19.6 μg F/g, kidney--56.0 μg F/g, and urine--1940 μg F/ml. In the second case, the contents of fluorine and zinc in blood and internal organs were the following: blood--6.03 μg F/ml, 23.8 μg Zn/ml; brain--1.39 μg F/g, 7.54 μg Zn/g; stomach--152 μg Zn/g; stomach content--293 μg F/g, 84.4 μg Zn/g; small intestine--37.5 μg Zn/g; small intestine content--63.4 μg F/g, 19.6 μg Zn/g; liver--9.49 μg F/g, 81.0 μg Zn/g; kidney--29.6 μg F/g, 39.2 μg Zn/g; and exceeded the normal levels of these elements in biological material many times. In addition, in stomach and liver large amounts of silica were detected. In the paper, a review of acute intoxications with various

    Animal bite is a bite wound from a pet, farm or wild animal. Dog bites make up 80-85% of all reported incidents. Cats amount for about 10% of reported bites and other animals such as rodents, rabbits, horses, raccoons, bats and monkeys amount to 5-10%. Bites by mongoose are uncommon. Here, we present a case of fatal mongoose bite to an elderly woman who died as a complication of streptococcal infection at the bite site. PMID:23166164

    Objectives To document overall, racial, ethnic and intent-specific spatiotemporal trends of firearm-related fatality rates (FRF rates) in the USA. Design Cross-sectional study per year from 2000 to 2010. Setting USA. Participants Aggregate count of all people in the USA from 2000 to 2010. Outcome measures Data from the Web-based Injury Statistics Query and Reporting System from 2000 to 2010 was used to determine annual FRF rates per 100 000 and by states, race, ethnicity and intent. Results The average national 11-year FRF rate was 10.21/100 000, from 3.02 in Hawaii to 18.62 in Louisiana: 60% of states had higher than national rates and 41 states showed no temporal change. The average national FRF rates among African-Americans and Caucasians were 18.51 and 9.05/100 000 and among Hispanics and non-Hispanics were 7.13 and 10.13/100 000; Hispanics had a decreasing change of −0.18, p trend<0.0001. In states with increasing trends (Florida and Massachusetts), Caucasians and non-Hispanics drove the rise; while in states with decreasing trends (California, North Carolina, Arizona, Nevada, New York, Illinois, Maryland), Hispanics and African-Americans drove the fall. The average national FRF rates due to homicides (4.1/100 000) and suicides (5.8/100 000) remained constant, but varied between states. Conclusions Endemic national FRF rates mask a wide variation in time trends between states. FRF rates were twice as high in African-Americans than Caucasians but decreased among Hispanics. Efforts to identify state-specific best practices can contribute to changes in national FRF rates that remain high. PMID:25239291

    A total population study of childhood fresh water drowning accidents (fatalities) for the 15 year period, 1967-1981, is reported. These data are from the ongoing Brisbane Drowning Study which has now also analysed 255 fresh water child immersions (both fatalities and near-fatalities) over the eleven year period, 1978-1981, and as such forms a consecutive unselected series for over one decade. The annual fatality (drowning) rate is 3.53 per 100,000. Details of immersion accidents by site, sex and by outcome (survivors versus fatalities) are presented. An analysis of secular trends revealed that one epidemic peak of child drownings in swimming pools and domestic baths (noted in the mid 1970s in Australia and other countries) is now passed. Evidence is presented to suggest that a vigorous education, and public awareness campaign can reduce the incidence of serious child immersion accidents by one-third. Such a campaign may have influence on all types of childhood household drownings (pools, baths, garden ponds), irrespective of site. Survival rates for unsupervised children who lose consciousness in fresh water are site-dependent, only 21% of such potential victims surviving after losing consciousness in rivers and creeks, compared with the survival rate of 65% for those in potential drowning incidents in their own backyard. Violent death continues to account for more than half of all deaths in childhood up to the age of 14 years [Gratz, 1979; Mayer, Walker and Johnson et al., 1981].(ABSTRACT TRUNCATED AT 250 WORDS)

    Diagnosis of dengue virus (DENV) infection in fatal cases is challenging because of the frequent unavailability of blood or fresh tissues. For formalin-fixed, paraffin-embedded (FFPE) tissues immunohistochemistry (IHC) can be used; however, it may not be as sensitive and serotyping is not possible. The application of reverse transcription-polymerase chain reaction (RT-PCR) for the detection of DENV in FFPE tissues has been very limited. We evaluated FFPE autopsy tissues of 122 patients with suspected DENV infection by flavivirus and DENV RT-PCR, sequencing, and DENV IHC. The DENV was detected in 61 (50%) cases by RT-PCR or IHC. The RT-PCR and sequencing detected DENV in 60 (49%) cases (DENV-1 in 16, DENV-2 in 27, DENV-3 in 8, and DENV-4 in 6 cases). No serotype could be identified in three cases. The IHC detected DENV antigens in 50 (40%) cases. The RT-PCR using FFPE tissue improves detection of DENV in fatal cases and provides sequence information useful for typing and epidemiologic studies.

    OBJECTIVE: The objective of this study was to describe fatal cases of traumatic brain injury (TBI) among West Virginia residents. METHODS: The authors analyzed data from the National Center for Health Statistics Multiple Cause of Death tapes for the period 1989-1998. They compared West Virginia's annualized average TBI death rate with the rates of other states and with the rate among U.S. residents for the same period. U.S. Bureau of Census population estimates were used as denominators. RESULTS: A total of 4,416 TBI deaths occurred in West Virginia in 1989-1998, for an annual average death rate of 23.6 per 100,000 population. From 1989 to 1998, TBI death rates declined 5% (p=0.4042). Seventy-five percent (n=3,315) of fatalities occurred among men. Adults > or =65 years of age accounted for the highest percentage of fatal injuries (n=1,135). The leading external causes of fatal TBI were: firearm-related (39% of reported fatalities), motor vehicles-related (34%), and fall-related (10%). Firearm-related TBI became the leading cause of TBI fatalities in 1991, surpassing motor vehicle-related TBI. Seventy-five percent of firearm-related TBI deaths were suicides (n=1,302). West Virginia's TBI death rate (23.6 per 100,000) was higher than the national rate (20.6 per 100,000). In 23 states, the average TBI death rates over the 10-year period were higher than West Virginia's. Whereas modest declines in TBI death rates occurred for motor vehicle-related and firearm-related causes in West Virginia, a concomitant 38% increase occurred in the fall-related TBI death rate during the decade. CONCLUSION: Data presented in this report can be used to develop targeted prevention programs in West Virginia. PMID:15313112

    Fatal acute methamphetamine (MA) poisoning in cases of internal drug trafficking is rarely described in the literature. This case study reports an MA 'body packer' who died from fatal methamphetamine intoxication due to leaking drug packages in the alimentary tract. The deceased was examined by postmortem computed tomography (PMCT), and the results were correlated to subsequent autopsy and toxicological findings. The deceased was arrested by the police when he was found disoriented in the city of Kuala Lumpur. He was transferred to the emergency department on suspicion of drug abuse. The initial drug screening was reactive for amphetamines. Shortly after admission to the hospital, he died despite rigorous resuscitation attempts. The postmortem plain chest and abdominal radiographs revealed multiple suspicious opacities in the gastrointestinal tract attributable to body packages. An unenhanced whole body PMCT revealed twenty-five drug packages, twenty-four in the stomach and one in the transverse colon. At least two were disintegrating, and therefore leaking. The autopsy findings were consistent with the PMCT results. Toxicology confirmed the diagnosis of fatal methamphetamine intoxication. PMID:23404531

    We report the fifth French case of fatal familial insomnia, characterized by a mutation at codon 178 of prion protein gene and by heterozygoty (Met/Val) at codon 129. The clinical picture included cerebellar ataxia, dysautonomia and frontal lobe syndrome. Prion protein gene analysis was performed in order to support a diagnosis of Creutzfeldt-Jakob disease and assert the diagnosis of fatal familial insomnia. Neuropathologic analysis showed unusual changes including severe neuronal loss in the inferior olive and the dentate nucleus, and absence of obvious lesions in the thalamus. Moreover, spongiform changes were moderate in the superior temporal cortex and the occipital cortex. There was no spongiform change in frontal cortex. Abnormal prion protein (PrP(res)) was mainly evidenced in the parietal cortex. Molecular genetic study of the PRNP gene should be performed in patients who present with a cerebellar ataxia of equivocal origin.

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

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

    Here, we investigated the possible role of the Nicotinamide Adenine Dinucleotide Phosphate oxidase NOX2-derived brain oxidative stress in a fatal case of cocaine-related neurotoxicity, associated to excited delirium syndrome. We detected a strong NOX2 immunoreactivity, mainly in cortical GABAergic neurons and astrocytes, with a minor presence in microglia, glutamatergic and dopaminergic neurons as well as a significant immunostaining for other markers of oxidative stress (8OhDG, HSP70, HSP90, and NF-κB) and apoptotic phenomena. These results support a crucial role of NOX2-derived brain oxidative stress in cocaine-induced brain dysfunctions and neurotoxicity. PMID:27533346

    Central nervous system (CNS) toxicity has been reported in approximately 10-30% of patients receiving intravenous infusions of ifosfamide. Encephalopathy is a rare but serious CNS adverse reaction in these patients, and although usually transient and reversible, may cause persistent neurological dysfunction or death. Clinical features range from fatigue and confusion to coma and death. Although methylene blue can be used to treat ifosfamide-induced neurotoxicity, including encephalopathy, its mechanism of action remains poorly defined. We describe here two patients with recurrent epithelial ovarian cancer who experienced fatal encephalopathy following ifosfamide/mesna treatment. PMID:22247713

    Parasailing is a recreational sport that is generally considered to be of little risk to the participants. Typically, the passenger launches from a motorboat with a specially designed winch that pulls him or her back to the boat at the end of the ride. The sport is not regulated at the federal, state, or county level. There have been few reports of injuries to parasailors. Additionally, there have been only 2 fatalities reported to the United States Coast Guard in a 10-year review. We report the details of these 2 deaths, those of a mother and daughter riding in a tandem parasail, which occurred on Fort Myers Beach in 2001, as well as an additional case of a parasailing fatality that occurred in southwest Florida in 1999. These cases illustrate the injuries seen in such fatalities and the hazards posed by adverse weather conditions and faulty equipment, as well as the impairment of passenger judgment by drugs and/or alcohol.

    The principal clinical and pathological findings in 16 fatal cases of human African trypanosomiasis caused by T.b. Gambiense are described. The changes in the brain took the form of a non-specific lymphoplasmacytic meningo-encephalitis of varying intensity. Other features included morular cells, diffuse microglial hyperplasia, and large reactive astrocytes in the white matter. Carditis was identified in 10 cases. Acute reactive arsenical encephalopathy appeared to be the principal cause of death in 10 patients. Convulsions figured prominently in this type of encephalopathy in seven patients and were sufficiently severe to produce hypoxic brain damage. In three cases of acute reactive arsenical encephalopathy the structural changes in the brain were those of acute haemorrhagic leucoencephalopathy.

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

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

    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.

    A fatal case of eosinophilic and granulomatous meningoencephalitis caused by the free-living panagrolaimid nematode Halicephalobus gingivalis is reported in a 10-year-old Welsh gelding in the United Kingdom. Clinical examination first revealed behavioural abnormalities which rapidly progressed to severe ataxia, reduced mentation status and cranial nerve signs. Despite symptomatic treatment no amelioration of neurological signs was achieved and the horse was subjected to euthanasia. A complete post mortem examination revealed eosinophilic and granulomatous meningoencephalitis mainly affecting the cerebellum and brain stem with intralesional adult nematodes, larvae and eggs. There was also eosinophilic meningitis of the cervical spinal cord. The intralesional nematodes were morphologically consistent with the panagrolaimid nematode H. gingivalis. Although infection by this facultative neurotropic parasite is extremely rare, it needs to be considered in the differential diagnosis of central nervous signs in horses and, in particular, other equine helminthic infection of the central nervous system. This fatal case is unusual since lesions were locally very extensive and the nematodes did not colonise haematogenously to other organs as seen often in equine halicephalobosis. As the taxonomy of H. gingivalis has changed and some recent reports in the literature still refer to this species as Micronema deletrix or Halicephalobus deletrix, we here provide a short update of the species and some insights on the order Tylenchida, which contains free-living nematodes with parasitic tendencies.

    Erlotinib is one of the most widely used tyrosine kinase inhibitor targeting human epidermal growth factor receptor. Since its introduction, it has revolutionized the treatment of advanced non-small cell lung cancer. Skin rashes and diarrhea are the most often reported side effects of erlotinib however it is also associated with interstitial pneumonitis or interstitial lung disease, which often turns out to be fatal complication of using this medicine. Though reported scarcely in the western world, the association of interstitial lung disease with epidermal growth factor receptor has attracted a lot of attention in the recent times. Various researches working with murine models of bleomycin-induced pulmonary fibrosis have found a pro and con role of the receptor in development of the interstitial lung disease. We present the case of a patient diagnosed with stage IV adenocarcinoma of the lung with metastasis to brain. He was found to be positive for the human epidermal growth factor mutation and was hence started on erlotinib. Within a few weeks of starting the medicine the patient was admitted with diarrhea. During the course of this admission he developed acute shortness of breath diagnosed as interstitial pneumonitis. The purpose of this case report is to review the literature associated with erlotinib induced interstitial pneumonitis and make the practicing oncologists aware of this rare yet fatal complication of erlotinib. Here we will also review literature, pertaining to the role of epidermal growth factor receptor in development of interstitial lung disease. PMID:27746884

    The New York Fatality Assessment and Control Evaluation (FACE) program is designed to identify and study fatal occupational injuries in New York State. The New York FACE program is supported by the National Institute for Occupational Safety and Health (NIOSH) and administered by the New York State Department of Health (NYS DOH) in cooperation with Cornell University. New York FACE investigators evaluate information from multiple sources, conduct objective on-site investigations, and then summarize their findings in narrative reports that include recommendations for preventing similar events in the future. These recommendations are distributed to employers, workers, and other organizations as an educational tool for promoting workplace safety. The following case study involved a 53-year-old dairy farm owner who was fatally injured while transferring manure from an underground storage pit to a manure lagoon. At the time of the incident, the farmer was utilizing a manure pump that was connected to a tractor via a power take-off (PTO) shaft. The farmer reached across the unshielded PTO shaft in order to operate a hand crank that adjusted the manure pump chute. As he did this, his clothing became entangled in the PTO shaft, wrapping the farmer's body around the shaft. New York FACE investigators concluded that to help prevent similar incidents from occurring in the future: PTO-powered equipment should not be operated unless the PTO shield is in place and in good condition; Power to equipment should be turned off prior to making mechanical adjustments; Manure handling systems should be designed to facilitate operator safety; Farm workers should be healthy and well rested prior to performing hazardous activities and; Dairy farm workers should be trained in manure handling safety and knowledgeable about other manure hazards.

    The insecticide propoxur (2-isopropoxyphenyl-N-methylcarbamate) acts by blocking cholinesterase. This inhibition is fast and, unlike that brought about by organophosphorus compounds, reversible. The toxicity of propoxur to man is stated to be low compared with that of parathion. Only a small number of fatal intoxications have been published; at the Würzburg University Institute of Legal Medicine eight cases have been observed since 1978. In seven cases death occurred after deliberate oral ingestion of solutions of propoxur with suicidal intent, while in the other, intoxication was accidental, following inhalation of an aerosol containing propoxur. Organs and body fluids were investigated toxicologically and histologically. The results are presented and discussed. Special attention is paid to the combination of propoxur and alcohol.

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

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

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

    Strongyloides stercoralis is an intestinal nematode that causes strongyloidiasis, which affects 30 to 100 million people worldwide. Risk factors for hyperinfection and disseminated disease include immunosuppressive drug therapy, human T-lymphotropic virus-1 (HTLV-1) infection, solid organ and bone marrow transplantation, hematologic malignant diseases, hypogammaglobulinemia, and severe malnutrition and associated conditions. The diagnosis can be difficult because a single stool examination fails to detect larvae in up to 70% of the cases, and the symptoms are nonspecific. Although eosinophilia is a common finding in patients with chronic Strongyloides infection, it is an unreliable predictor of hyperinfection. Furthermore, the lack of eosinophilia while receiving immunosuppressive therapy cannot reliably exclude the underlying chronic Strongyloides infection. We report here a fatal Strongyloides hyperinfection in a patient receiving allogeneic stem cell transplantation; risk factors and outcome in this clinical setting are discussed. PMID:23936693

The study includes 245 death cases between 1971 and 1988 (1% of all autopsies). 66 cases proved to be natural deaths, 76 were classified as suicides, 39 as accidents and 13 as homicides; 51 fatalities remained unclear with respect to one of these groups. Among the natural deaths sudden cardiac deaths were dominating (n = 39), among the suicides the intoxications (n = 37) and electrocutions (n = 20), and among the accidents the intoxications by carbon monoxide (n = 17) and electrocutions (n = 12). Out of 13 homicides only 2 were committed directly in the bathtub: One by drowning of a child and one by electric current via a hair dryer; in the other cases the dead body was put into the bathtub post mortem. About 50% of the victims were alcoholized. Signs of drowning were present in about 40% of all cases; the most frequent finding was emphysema aquosum.

    Athletes are often advised to drink in order to "fully replace bodyweight losses" in order to prevent exertional heatstroke (EHS) during exercise in the heat. There is little evidence that "dehydration" in the range experienced by athletes adversely affects thermoregulation or is the exclusive cause of EHS. In contrast it is established that excess fluid intake can cause exercise-associated hyponatremia (EAH) sometimes associated with encephalopathy (EAHE). As part of a series of experiments to determine optimal fluid replacement during exercise in the heat, we studied a group of exceptionally well-conditioned and heat-adapted members of the South African National Defence Force. A 20 year old male started a time restricted 50 km route-march in a dry bulb temperature that reached 37.5°C (WBGT of 33.6°C, relative humidity of 85%). Pre-march plasma osmolality, serum [Na(+)] and total body water measures indicated euhydration. Fluid was available ad libitum and isotonic sports drinks at 5 km intervals. Fluid intake and core body temperature (Tc) were recorded throughout while he was tracked by a global positioning system measuring distance travelled, position and speed. Comparing the total fluid intake of the soldier (12930 mL) to the rest of the participants (mean intake of 9 038 mL) up to 40 km, it is evident that his intake was 3892 mL (approximately 300 mL h(-1)) more than the mean for group. At approximately 17h14 the soldier was found lying by himself at the side of the route, 2.24 km from the finish point. He passed away the next day in a medical care facility. This tragic event provides the valuable opportunity to present data on the pacing, temperature regulation and fluid consumption of an exceptional athlete during the development of a fatal case of combined EAHE and EHS. Pacing, fluid intake, Tc and environmental condition data are presented for 5 km intervals throughout the march. We propose a novel hypothesis on the possible contribution of EAHE to the

    A highly lethal hemorrhagic disease associated with infection by elephant endotheliotropic herpesvirus (EEHV) poses a severe threat to Asian elephant husbandry. We have used high-throughput methods to sequence the genomes of the two genotypes that are involved in most fatalities, namely, EEHV1A and EEHV1B (species Elephantid herpesvirus 1, genus Proboscivirus, subfamily Betaherpesvirinae, family Herpesviridae). The sequences were determined from postmortem tissue samples, despite the data containing tiny proportions of viral reads among reads from a host for which the genome sequence was not available. The EEHV1A genome is 180,421 bp in size and consists of a unique sequence (174,601 bp) flanked by a terminal direct repeat (2,910 bp). The genome contains 116 predicted protein-coding genes, of which six are fragmented, and seven paralogous gene families are present. The EEHV1B genome is very similar to that of EEHV1A in structure, size, and gene layout. Half of the EEHV1A genes lack orthologs in other members of subfamily Betaherpesvirinae, such as human cytomegalovirus (genus Cytomegalovirus) and human herpesvirus 6A (genus Roseolovirus). Notable among these are 23 genes encoding type 3 membrane proteins containing seven transmembrane domains (the 7TM family) and seven genes encoding related type 2 membrane proteins (the EE50 family). The EE50 family appears to be under intense evolutionary selection, as it is highly diverged between the two genotypes, exhibits evidence of sequence duplications or deletions, and contains several fragmented genes. The availability of the genome sequences will facilitate future research on the epidemiology, pathogenesis, diagnosis, and treatment of EEHV-associated disease. PMID:23552421

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

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

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

    Anabolic androgenic steroids (AAS) are the main class of doping agents and their consumption produces adverse effects involving several organs and systems. Three cases of sudden cardiac death (SCD) and one of death due to congestive heart failure of previously healthy athletes who were AAS users are herein reported. Concentric cardiac hypertrophy with focal fibrosis (one case), dilated cardiomyopathy with patchy myocyte death (two cases) and eosinophilic myocarditis (one case) were observed and most probably relate to the final event. Molecular investigation for viral genomes was positive in one case (Ebstein virus). Our data confirm previous findings, showing that the most typical cardiac abnormality in AAS abusers is left ventricular hypertrophy, associated with fibrosis and myocytolysis. An exceptional cardiovascular substrate was represented by the case with drug induced eosinophilic myocarditis. These features are at risk of ventricular arrhythmias as well as congestive heart failure. The cause-effect relationship between AAS abuse and cardiac death can be established only by a rigorous methodology with the use of standardized protocols, including precise morphological studies of all target organs to search for chronic toxic effects. Laboratory investigations should focus on AAS searching on a wide range of biological matrices to demonstrate type, magnitude and time of exposure.

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

    The study includes medicolegally examined fatal poisonings among drug addicts in 1997 in the five Nordic countries: Denmark, Finland, Iceland, Norway and Sweden, and the results are compared to a similar investigation from 1991. A common definition of "drug addict" was applied by the participating countries. The highest death rate by poisoning in drug addicts was observed in Denmark, where it was 6.54 per 10(5)inhabitants, followed by Norway with 6.35, Sweden with 2.21, Finland with 1.63 and Iceland with 1.20 per 10(5)inhabitants. All countries showed a higher death rate in 1997 than in 1991. 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. Apart from two cases in Sweden methadone deaths were not seen in the other Nordic countries. In Finland heroin/morphine deaths have increased from about 10% in 1991 to about 40% in 1997. Forty-four percent of the fatal poisonings in Finland were caused by other group I drugs, mainly codeine and propoxyphene. The two fatal poisonings in Iceland were caused by carbon monoxide. Only few deaths in this investigation were caused by amphetamine and cocaine. A widespread use of alcohol, cannabis and benzodiazepines, especially diazepam, was seen in all the countries.

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

    Background Rocky Mountain spotted fever (RMSF) is a disease that now causes significant morbidity and mortality on several American Indian reservations in Arizona. Although the disease is treatable, reported RMSF case fatality rates from this region are high (7%) compared to the rest of the nation (<1%), suggesting a need to identify clinical points for intervention. Methods The first 205 cases from this region were reviewed and fatal RMSF cases were compared to nonfatal cases to determine clinical risk factors for fatal outcome. Results Doxycycline was initiated significantly later in fatal cases (median, day 7) than nonfatal cases (median, day 3), although both groups of case patients presented for care early (median, day 2). Multiple factors increased the risk of doxycycline delay and fatal outcome, such as early symptoms of nausea and diarrhea, history of alcoholism or chronic lung disease, and abnormal laboratory results such as elevated liver aminotransferases. Rash, history of tick bite, thrombocytopenia, and hyponatremia were often absent at initial presentation. Conclusions Earlier treatment with doxycycline can decrease morbidity and mortality from RMSF in this region. Recognition of risk factors associated with doxycycline delay and fatal outcome, such as early gastrointestinal symptoms and a history of alcoholism or chronic lung disease, may be useful in guiding early treatment decisions. Healthcare providers should have a low threshold for initiating doxycycline whenever treating febrile or potentially septic patients from tribal lands in Arizona, even if an alternative diagnosis seems more likely and classic findings of RMSF are absent.

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

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

    Sodium phosphate enemas and laxatives are widely used for the treatment of constipation, even if a number of cases of significant toxicity due to alterations of the fluid and electrolyte equilibria (hypernatremia, hyperphosphatemia, and hypocalcemia) have been reported. We present the case of an 83-year-old man who died of fecal and chemical peritonitis secondary to an iatrogenic colon perforation (produced performing a Fleet enema through the patient's iliac colostomy) with peritoneal absorption of sodium phosphate. Environmental scanning electron microscopy coupled with an X-ray fluorescence energy dispersive spectrometry discovered multiple bright crystals formed of calcium, phosphorus, and oxygen in the brain, heart, lung, and kidney sections of the victim. The absence of these kinds of precipitates in two control samples chronically treated with Fleet enemas led us to assume that the deceased had adsorbed a great quantity of phosphorus ions from the peritoneal cavity with subsequent systemic dissemination and precipitation of calcium phosphate bindings.

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

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

    Bullet identification by chemical analysis often provides a powerful clue in forensic science. A case is reported in which a hunting accident was resolved by using instrumental neutron activation analysis (INAA) for direct comparison of the trace element content in lead shot. Different preparation batches of lead shot appear to have a high within-group composition homogeneity, and good differentiation is achieved between different batches. Determination of the nickel and antimony content on a bush branch demonstrated that the branch had been perforated by one of the shot pellets, and this helped the detectives in reconstruction of the crime scene.

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

    The aim of this study was to present the characteristics of medicolegal autopsies of fatal poisonings in Trabzon (Turkey), performed from 1998 to 2008, to contribute to the available data on this topic. A retrospective study of the forensic records and the toxicological data of all autopsies performed over that period revealed that 285 cases (6.34%) of the 4492 total autopsies performed were attributed to fatal poisoning. Major toxic substances were classified in five categories as follows: carbon monoxide (CO), insecticides, prescription medications, narcotic drugs, and alcohol (methyl and ethyl). CO was the most frequent cause of death (63.2%), followed by insecticides (17.2%), prescription medications and narcotic drugs (9.8%), alcohol (7.7%), and others (mushroom, rodenticide, and botulism) (2.1%). Ages of the patients ranged from 1 to 86 years (21.55 ± 36.56). PMID:21447071

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

    A 19 year old male was admitted to a tertiary care centre in Sri Lanka, with a history of snake bite while sleeping at night. A killed specimen of a snake was brought with the patient. It had been identified as a non-venomous snake by the doctor and handed over to relatives, with a comment to that effect. Patient had no clinical or laboratory evidence of envenoming on admission. Patient developed bilateral ptosis six hours after alleged snake bite, soon followed by respiratory paralysis and was treated with Indian polyvalent anti-venom serum. After 12 h of the bite, patient had developed hypotension that did not respond to ionotropes. Despite intensive management, patient had become deeply comatose and deceased 46 h following the snake bite. Autopsy revealed features suggestive of disseminated intravascular coagulation. Since an allegation of medical negligence too had been levelled by the relations of the patient against the clinical staff, the buried specimen of the snake was recovered by police, on a judicial order, a week later. It was found to be almost completely disintegrated and only the scales and bones were remaining. According to the scale characters, the reconstructed specimen was identified as Indian krait (Bungarus caeruleus). Authentication of snake is important in investigating a death due to snake bite, especially when the snake was initially claimed to be a non-venomous snake. This case suggests the usefulness of forensic identification of species of the snake in investigating suspected snake bite cases. PMID:24237800

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

    Morbidity and mortality from road traffic accidents in Bangkok metropolis is high with a trend strictly increasing in time, thus establishing one of the major public health problems and targets of the Kingdom of Thailand. An unmatched case-control study was undertaken to evaluate various risk patterns connected with the occurrence of traffic accidents. 350 cases were sampled from five major hospitals distributed over the Bangkok Metropolitan area and 350 controls were included from out-patients of Rajawithi hospital. The major interest in this case-control analysis is to estimate relative risk (through odds ratio) and measure statistical significance of association between road traffic accident and the following risk factors: the demographic risk factors are age (age between 15 and 19 years has odds ratio of 8.25 [1.01, 67.72]; age above 40 is baseline), marital status (single has odds ratio of 2.74 [1.26, 5.95]; baseline is not-single), sex (males have an odds ratio of 2.05 [0.51, 8.24], occupation (salespersons have an odds ratio of 4.27 [1.47, 12.46]; baseline are office workers); the driving related exposure factors type of vehicle (motorbikers have an odds ratio of 6.22 [2.82, 13.78]; baseline are other vehicle drivers), driving time per day (odds ratio 1.35 [0.88, 2.09]) and the number of accidents in the last three years (odds ratio of 4.36 [2.51, 7.58]); the behavioral factors one hour before driving such as the consumption of alcohol (odds ratio 3.01 [1.53, 5.94]; baseline in no alcohol) and the consumption of a lot of food (odds ratio of 0.07 [0.03, 0.16]; baseline is not eating a lot before driving). The odds ratios for traffic accident when being under allergic medication and the consumption of tranquilizer were not significant. The results are consistent with current results in traffic accident research and point to target groups for potential prevention programmes in traffic accident prevention. PMID:9499466

    An unprecedented dengue outbreak involving more than 15,000 infections, including 136 dengue hemorrhagic fever (DHF) cases and 20 fatalities, occurred in Taiwan in 2014. The median age of the DHF cases was 71 years (range: 4-92 years) and most of them (N = 100, 73.5%) had comorbidities, of which the majority were hypertension (56%) and diabetes mellitus (DM; 27%). Only approximately half of the DHF cases (59/136) were classified as severe dengue, based on the 2009 WHO-revised dengue classification. The fatality rate for this DHF outbreak was 14.7%. DM (odds ratio [OR] = 3.60, 95% confidence interval [CI] = 1.22-10.63) and presentation with severe plasma leakage (OR = 6.42, 95% CI = 1.76-23.63) were independent risk factors for fatality.

    JC virus (JCV) is the etiologic agent of progressive multifocal leukoencephalopathy, JCV granule cell neuronopathy, and JCV encephalopathy. Whether JCV can also cause meningitis has not yet been demonstrated. We report a case of aseptic meningitis resulting in symptomatic hydrocephalus in a human immunodeficiency virus-seronegative patient. Brain imaging showed enlargement of ventricles but no parenchymal lesion. She had a very high JC viral load in the cerebrospinal fluid (CSF) and developed progressive cognitive dysfunction despite ventricular drainage. She was diagnosed with pancytopenia and passed away after 5.5 months. Postmortem examination revealed productive JCV infection of leptomeningeal and choroid plexus cells, and limited parenchymal involvement. Sequencing of JCV CSF strain showed an archetype-like regulatory region. Further studies of the role of JCV in aseptic meningitis and in idiopathic hydrocephalus are warranted.

    Traumatic brain injury is a common entity. However cerebral infarction in infants is a rare entity while the diagnosis of this pathology in the pediatric population is usually difficult. The mild head trauma is rarely accompanied by intracranial injury and even less, with cerebral infarction. We herein report the first case of cerebral infarction after a mild brain trauma in a 2-year-old Latin-American male patient, in which brain computed tomography (CT) scan was performed on the first day of the accident, showed right hemispheric cerebral ischemia compromising the fronto-parieto-occipital region. Conservative management was established. The patient died at day 5. So Brain CT scan may be beneficial to reveal any hemispheric infarction due to a probable mass effect.

    Life-threatening refractory metabolic acidosis due to starvation ketoacidosis is rarely reported, even among nondiabetic pregnant women, and may be overlooked. Furthermore, stressful situations may increase the acidosis severity.In the present case, a nondiabetic multiparous woman was admitted for a near-fatal asthma attack and vomiting during the third trimester of pregnancy. She was intubated and rapidly developed high anion gap metabolic acidosis. We diagnosed the patient with starvation ketoacidosis based on vomiting with concomitant periods of stress during pregnancy and the absence of other causes of high anion gap metabolic acidosis. She responded poorly to standard treatment, although the ketoacidosis and asthma promptly resolved after an emergency caesarean section. The patient and her baby were safely discharged.Short-term starvation, if it occurs during periods of stress and medication, can result in life-threatening ketoacidosis, even among nondiabetic women during the third trimester of pregnancy. Awareness of this condition may facilitate prompt recognition and proactive treatment for dietary and stress control, and emergent interventions may also improve outcomes.

    Recent studies suggest an association between red cell distribution width (RDW) and incident venous thromboembolism (VTE). We aimed to investigate the impact of RDW on risk of incident and recurrent VTE, and case-fatality, in a general population. RDW was measured in 26,223 participants enrolled in the Tromsø Study in 1994-1995. Incident and recurrent VTE events and deaths during follow-up were registered until January 1, 2012. Multivariate Cox proportional hazards regression models were used to calculate hazard ratios (HR) with 95% confidence intervals (CI). There were 647 incident VTE events during a median of 16.8 years of follow-up. Individuals with RDW in the highest quartile (RDW≥13.3%) had 50% higher risk of an incident VTE than those in the lowest quartile (RDW≤12.3%). The association was strongest for unprovoked deep-vein thrombosis (HR highest vs lowest quartile of RDW: 1.8, 95% CI 1.1-3.1). VTE patients with baseline RDW≥13.3% had 30% higher risk of all-cause mortality after the initial VTE event than VTE patients with RDW<13.3%. There were no association between RDW and risk of recurrent VTE. Our findings suggest that high RDW is a risk factor of incident VTE, and that RDW is a predictor of all-cause mortality in VTE patients.

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

    MCPA (4-chloro-2-methyl phenoxyacetic acid) is a systemic hormone-type selective herbicide readily absorbed by leaves and roots. Use of MCPA for murder or attempted murder is very rare in Sri Lanka. However, a reported case of attempted murder by adding MCPA to water will be discussed in this paper. Three extraction methods were carried out with urine samples spiked with MCPA, namely liquid-liquid extraction with chloroform, solid phase extraction using C18 cartridges and vortex mixing with methanolic hydrochloric acid. Based on the recovery results, solid phase extraction was selected as the most suitable method and applied in the analysis of urine and water samples. Identification of MCPA in urine, water and the suspected poison bottle was carried out by HPLC and was confirmed by GC-MS. 4-chloro -2- methyl phenol metabolite was also identified and confirmed in the urine sample of the patient by GC-MS. Quantitative analysis of MCPA was carried out by HPLC using a validated method where Zorbax XDB-C18 column was used with photo diode array detector. In this case, presence of MCPA in one patient's urine sample collected four days after the incident was confirmed by GC-MS and found at a concentration of 0.83μg/ml. MCPA was not identified in the urine samples collected after 13 days in other three patients. The water sample taken from the suspected water storage tank found to contain 101μg/ml of MCPA. The results showed that HPLC combined with GC-MS is suitable for forensic analysis of MCPA in urine. PMID:24867053

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

    The study includes 122 medico-legally examined fatal poisonings with illegal drugs in Slovenia (1.96 million inhabitants) in years 1997-2003. The highest death rate expressed per 10(5) inhabitants per year was observed in the year 2002 with 1.17, the average value over 1997-2003 was 0.89; the trend line shows a stabilisation. Heroine/morphine dominated as the cause of death and were responsible for 71.3% of the fatal poisonings. Methadone was found to cause or contributed to death in 28 cases (22.9%). One death by cocaine and two by MDMA were caused in the time observed. Males represent 98.4% of the direct illegal drug-related deaths. The main ages of heroine/morphine group, heroine/morphine only and methadone group were 27.6, 24.1 and 26.8, respectively. Between 1997 and 2003, there was a downward trend in the average age in the group heroine/morphine only. Since 2001, we are the part of the national working group on key indicator "drug-related mortality" applying EMCDDA methodology.

    Fatal anaphylactic reactions to foods are continuing to occur, and better characterization might lead to better prevention. The objective of this report is to document the ongoing deaths and characterize these fatalities. We analyzed 32 fatal cases reported to a national registry, which was established by the American Academy of Allergy, Asthma, and Immunology, with the assistance of the Food Allergy and Anaphylaxis Network, and for which adequate data could be collected. Data were collected from multiple sources including a structured questionnaire, which was used to determine the cause of death and associated factors. The 32 individuals could be divided into 2 groups. Group 1 had sufficient data to identify peanut as the responsible food in 14 (67%) and tree nuts in 7 (33%) of cases. In group 2 subjects, 6 (55%) of the fatalities were probably due to peanut, 3 (27%) to tree nuts, and the other 2 cases were probably due to milk and fish (1 [9%] each). The sexes were equally affected; most victims were adolescents or young adults, and all but 1 subject were known to have food allergy before the fatal event. In those subjects for whom data were available, all but 1 was known to have asthma, and most of these individuals did not have epinephrine available at the time of their fatal reaction. Fatalities due to ingestion of allergenic foods in susceptible individuals remain a major health problem. In this series, peanuts and tree nuts accounted for more than 90% of the fatalities. Improved education of the profession, allergic individuals, and the public will be necessary to stop these tragedies.

    Mucormycosis and aspergillosis are two opportunistic fungal infections, which can evolve into life-threatening complications. They generally affect patients with relevant risk factors such as immunocompromisation or long-term use of antibiotics or corticosteroids. Treatment usually combines medical and surgical approaches, often including extended necrosectomies, although the prognosis of generalized fungal infections is very poor. In this paper, we present the case of a 17-year-old girl affected by combined aspergillosis and mucormycosis, following treatment of a recurrent glioma. The patient was hospitalized for a suspected cellulitis of the right hemi-face, involving frontal maxillary area and the upper airways and was immediately put on intravenous antibiotic therapies; after performing nasal septum and maxillary biopsies, concomitant mucormycosis and aspergillosis were diagnosed and antimycotic therapy with liposomal B-amphotericin was administered. After evaluation by the oral surgeon and otolaryngologist, surgical cranio-facial necrosectomy was suggested, but refused by the parents of the patient. The girl died only few days later, due to a respiratory arrest. Awareness of this pathology with prompt diagnosis and early treatment may improve the outcome of these infections and reduce the mortality. PMID:27350324

    This case study explores a scenario that was observed by a final year nursing student on placement in a paediatric emergency department, in a busy London teaching hospital. A mother appeared distressed following the news that her son who had survived a road traffic incident with minimal impact to his cognitive and physical abilities, was stable enough to be transferred to the children's medical ward. Whilst this appeared to be positive for supporting figures in her life and the emergency practitioners involved, observation and discussion with the mother revealed that her distress was related to her experience of losses that were undetected by those around her. This included losses related to her son's future and the loss of her previous world. Amongst the plethora of theories about how we as humans react to loss and change, one theory which could explain the mother's grief suggests that it was disenfranchised, i.e. it was not acknowledged or validated by society. There are consequences of disenfranchised grief, such as a lack of social support leading to a higher risk of adverse psychological outcomes. Nurses in the emergency department can help resolve negative outcomes for patients and families experiencing disenfranchised grief. The key steps are to have knowledge of disenfranchised grief to be able to detect it, and then to validate it as a form of grief. PMID:24183108

    The first case involving repetitive sexual abuse linked to the use of buprenorphine is reported. Under the tradename Subutex, buprenorphine is largely used for the substitution management of opiate-dependent individuals, but it can also be easily found on the black market. A 14-year-old boy was found dead at the home of a well-known sex offender of minors. At the autopsy, no particular morphological changes were noted, except for pulmonary and visceral congestion. There was no evidence of violence, and no needle marks were found by the pathologist. Toxicological analyses, as achieved by liquid chromatography-mass spectrometry, demonstrated both recent and repetitive buprenorphine exposure in combination with nordiazepam. Buprenorphine concentrations were 1.1 ng/mL and 23 pg/mg in blood and hair, respectively. The boy's death was attributed to accidental asphyxia in a facilitated repetitive sexual abuse situation due to the combination of buprenorphine and benzodiazepines, even at therapeutic concentrations. The use of buprenorphine as a sedative drug was not challenged by the perpetrator. PMID:14607012

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

    No other clinical entity has attached more attention now-a-day than those precipitated by the infection with a Hemorrhagic Fever Virus. Potentially caused by Arena, Bunya, Flavi, and Filoviradae, only the latter has had such a major impact throughout the world. Two major genuses have been recognized since they become evident for the first time in 1967, the single-species Marburg, and the 3-species-Ebola (E. zaire, sudan and reston). With the exception of the 2 outbreaks of E. reston (Washington, USA 1989-1993), all of them have taken place in Africa, where the virus is still hiding among the wild-life of the Tropical Rain Forest. Currently (in April 1995) the reemergence of Ebola virus has once more proven its fatality, leaving around 170 deaths in Zaire, 250 miles from its capital, Kinshasa. There is worldwide alert, sponsored by the CDC in Atlanta, the World Health Organization and the authorities in Zaire regarding its potential spreading to naive regions, in and out of Africa. The characteristic clinical picture of a viral hemorrhagic fever has no match. After a 2-21 days incubation period a viral-like illness develops. As days go by, symptoms worsen, and by the 7th day, a severe and diffuse bleeding tendency ensues. The individual's death is the most likely outcome in the great majority of cases. As a lethal virus, without an available treatment and a possible airborne-route of transmission, Ebola virus will always be considered a persistent threat to the global health.

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

    OBJECTIVES--To assess the effects of cigarette smoking on the incidence of non-fatal myocardial infarction, and to compare tar in different types of manufactured cigarettes. METHODS--In the early 1990s responses to a postal questionnaire were obtained from 13,926 survivors of myocardial infarction (cases) recently discharged from hospitals in the United Kingdom and 32,389 of their relatives (controls). Blood had been obtained from cases soon after admission for the index myocardial infarction and was also sought from the controls. 4923 cases and 6880 controls were current smokers of manufactured cigarettes with known tar yields. Almost all tar yields were 7-9 or 12-15 mg/cigarette (mean 7.5 mg for low tar (< 10 mg) and 13.3 for medium tar (> or = 10 mg). The cited risk ratios were standardised for age and sex and compared myocardial infarction rates in current cigarette smokers with those in non-smokers who had not smoked cigarettes regularly in the past 10 years. RESULTS--At ages 30-49 the rates of myocardial infarction in smokers were about five times those in non-smokers (as defined); at ages 50-59 they were three times those in non-smokers, and even at ages 60-79 they were twice as great as in non-smokers (risk ratio 6.3, 4.7, 3.1, 2.5, and 1.9 at 30-39, 40-49, 50-59, 60-69, 70-79 respectively; each 2P < 0.00001). After standardisation for age, sex, and amount smoked, the rate of non-fatal myocardial infarction was 10.4% (SD 5.4) higher in medium tar than in low tar cigarette smokers (2P = 0.06). This percentage was not significantly greater at ages 30-59 (16.6% (7.1)) than at 60-79 (1.0% (8.5)). In both age ranges the difference in risk between cigarette smokers and non-smokers was much larger than the difference between one type of cigarette and another (risk ratio 3.39 and 3.95 at ages 30-59 for smokers of similar numbers of low and of medium tar cigarettes, and risk ratio 2.35 and 2.37 at ages 60-79).

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

    Fatal food-induced anaphylaxis is rarely reported. In 16 months, we identified seven such cases involving five males and two females, aged 11 to 43 years. All victims were atopic with multiple prior anaphylactic episodes after ingestion of the incriminated food (peanut, four; pecan, one; crab, one; fish, one). In six cases the allergenic food was ingested away from home. Factors contributing to the severity of individual reactions included denial of symptoms, concomitant intake of alcohol, reliance on oral antihistamines alone to treat symptoms, and adrenal suppression by chronic glucocorticoid therapy for coexisting asthma. In no case was epinephrine administered immediately after onset of symptoms. Premortem or postmortem serum samples were available from six victims; in each case elevated levels of IgE antibodies to the incriminated food were demonstrated. Food-sensitive individuals must self-administer epinephrine promptly at the first sign of systemic reaction. Emergency care providers should be aware of cricothyrotomy as a life-saving procedure.

    1999-09-01

    Data on occupational accidents are not available from all countries in the world. Furthermore, underreporting, limited coverage by reporting and compensation schemes, and non-harmonized accident recording and notification systems undermine efforts to obtain worldwide information on occupational accidents. This paper presents a method and new estimated global figures of fatal accidents at work by region. The fatal occupational accident rates reported to the International Labour Office are extended to the total employed workforce in countries and regions. For areas not covered by the reported information, rates from other countries that have similar or comparable conditions are applied. In 1994, an average estimated fatal occupational accident rate in the whole world was 14.0 per 100,000 workers, and the total estimated number of fatal occupational accidents was 335,000. The rates are different for individual countries and regions and for separate branches of economic activity. In conclusion, fatal occupational accident figures are higher than previously estimated. The new estimates can be gradually improved by obtaining and adding data from countries where information is not yet available. Sectoral estimates for at least key economic branches in individual countries would further increase the accuracy.

    Background 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. Methods and Findings 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. Conclusions 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

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

    This study examines 1970-78 South Carolina firearm fatalities utilizing vital record data. During this period, 5,808 firearm deaths, classified as accident, homicide, suicide, or undetermined, were reported with an average annual fatality rate of 23.35 deaths per 100,000 estimated population. Firearm fatalities in South Carolina were the sixth leading cause of death in 1975 and accounted for 2.9 per cent of all deaths to residents. A significant period decline in the firearm fatality rate was observed and was attributed mainly to decreases in the non-White rate. In 1978, the fatality rate for non-Whites (18.5) fell below the rate for Whites (19.1) for the first time in the years investigated. Firearm deaths represent a major community health problem and, as such, warrant attention and direct involvement by state and local health professionals. PMID:3966623

    OBJECTIVES--To describe the types and circumstances of traumatic work related fatalities in Australian commercial fishermen. METHODS--Work related traumatic fishing fatalities were studied as part of a larger study of all work related traumatic fatalities in Australia from 1982 to 1984. Data on 47 cases were obtained from inspection of coroners' files. RESULTS--The incidence of fatality of 143/100,000 person-years was 18 times higher than the incidence of fatality for the entire workforce, and considerably higher than that of the mining and agricultural workforces. 68% of decedents drowned and 13% died from physical trauma. Rough weather, non-seaworthy vessels, inadequate use of personal flotation devices, and inexperience were associated with many of the fatal incidents. DISCUSSION--Improved vessel and equipment maintenance, better training of workers, greater use of personal flotation devices, and development of improved clothing and personal flotation devices are recommended.

    We report two cases in which men used the hydraulic shovels on tractors to suspend themselves for masochistic sexual stimulation. One man developed a romantic attachment to a tractor, even giving it a name and writing poetry in its honor. He died accidentally while intentionally asphyxiating himself through suspension by the neck, leaving clues that he enjoyed perceptual distortions during asphyxiation. The other man engaged in sexual bondage and transvestic fetishism, but did not purposely asphyxiate himself. He died when accidentally pinned to the ground under a shovel after intentionally suspending himself by the ankles. We compare these cases with other autoerotic fatalities involving perceptual distortion, cross-dressing, machinery, and postural asphyxiation by chest compression. PMID:8454997

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

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

    A novel avian influenza A (H7N9) virus caused 5-10 % mild and 30.5 % fatal human infections as of December 10, 2015. In order to investigate the reason for the higher rate of fatal outcome of this infection, this study compared the molecular epidemiology and virology of avian influenza A (H7N9) viruses from mild (N = 14), severe (N = 50) and fatal (N = 35) cases, as well as from non-human hosts (N = 73). The epidemiological results showed that the average age of the people in the mild, severe and fatal groups was 27.6, 52 and 62 years old, respectively (p < 0.001). Males accounted for 42.9 % (6/14), 58.0 % (29/50), and 74.3 % (26/35) of cases in the mild, severe and fatal group respectively (p = 0.094). Median days from onset to start of antiviral treatment were 2, 5 and 7 days in the mild, severe and fatal group, respectively (p = 0.002). The median time from onset to discharge/death was 12, 40 and 19 days in the mild, severe and fatal group, respectively (p < 0.001). Analysis of whole genome sequences showed that PB2 (E627K), NA (R294K) and PA (V100A) mutations were markedly associated with an increased fatality rate, while HA (N276D) and PB2 (N559T) mutations were clearly related to mild cases. There were no differences in the genotypes, adaptation to mammalian hosts, and genetic identity between the three types of infection. In conclusion, advanced age and delayed confirmation of diagnosis and antiviral intervention were risk factors for death. Furthermore, PB2 (E627K), NA (R294K) and PA (V100A) mutations might contribute to a fatal outcome in human H7N9 infection. PMID:26887968

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

    Previous epidemiological studies of rollover crashes have focused primarily on serious and fatal injuries in general, while rollover crash testing has focused almost exclusively on cervical spine injury. The purpose of this study was to examine and compare the risk factors for cervical spine, head, serious, and fatal injury in real world rollover crashes. Rollover crashes from 1995-2008 in the National Automotive Sampling System-Crashworthiness Data System (NASS-CDS) were investigated. A large data set of 6015 raw cases (2.5 million weighted) was generated. Nonparametric univariate analyses, univariate logistic regression, and multivariate logistic regression were conducted. Complete or partial ejection, a lack of seatbelt use, a greater number of roof inversions, and older occupant age significantly increased the risk of all types of injuries studied (p<0.05). Far side seating position increased the risk of fatal, head, and cervical spine injury (p<0.05), but not serious injury in general. Higher BMI was associated with an increased risk of fatal, serious, and cervical spine injury (p<0.05), but not head injury. Greater roof crush was associated with a higher rate of fatal and cervical spine injury (p<0.05). Vehicle type, occupant height, and occupant gender had inconsistent and generally non-significant effects on injury. This study demonstrates both common and unique risk factors for different types of injuries in rollover crashes. PMID:22269486

    An upsurge in gun violence in recent times in our environment necessitated this study, which aims to document the patterns of fatal gunshot injuries with the hope of finding a solution to this problem. The study was a retrospective analysis of cases of fatal gunshot injuries on which autopsies were carried out over the 5-year period from January 1998 to December 2002 at Police Medical Services, Benin City - a Nigerian ancient town located in the South-South zone of the country. Most cases of medico-legal death in Benin City and environs are referred to the Police Pathologist at the center for autopsy. A total of 210 cases representing 27.2% of all medico-legal deaths during the study period were reviewed. Males were far more affected than females (M:F = 10.7:1). The intent for the fatal gunshots was murder (88.5%), excusable homicide (4.8%), accident (4.3%) and suicide (0.5%). In 1.9% of the deaths, the circumstances were not clear. Armed robbers, thugs and assassins accounted for 88.1% of the fatal shots, while the Police accounted for 9.0%. The trunk was affected much more than the head, neck and limbs. There is a need to improve security in the country and reduce poverty. Illegal firearms should also be removed from circulation. An improvement in emergency health services will reduce deaths from gunshots.

Women's or fetish clothing and complex shackling or hanging devices were disproportionately frequent. In most cases, death occurred due to hanging or ligature strangulation. There was no increased incidence of underlying psychiatric disorders. In most of the deceased no or at least no remarkable alcohol intoxication was found. Occasionally, it may be difficult to reliably differentiate autoerotic accidents, accidents occurring in connection with practices of bondage & discipline, dominance & submission (BDSM) from natural death, suicide or homicide.

    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.

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

  13. Fatal cardiopulmonary complications in children treated with ventriculoatrial shunts.

    During the years from 1965 to 1986, 716 children underwent a total of 2065 shunt procedures in our department. Of these, 1298 were ventriculoatrial (VA). Until 1979, Pudenz VA shunts were almost exclusively used as the primary procedure as well as in revisions. Since 1980, mini-Holter VA shunts have been implanted as a second choice, usually in cases with repeated distal failure in ventriculoperitoneal (VP) shunts. Observation time for children with VA shunts is therefore from 10 to 23 years for the great majority. The cumulative death rate for all patients is 24% (175/716), 9% (64/716) being tumor patients who eventually died as a result of their neoplasm. Most of the other deaths were caused by shunt infection or occurred in a group of children where shunts had been implanted for palliative reasons and where follow-up was only sporadic. Among the 450 children with VA shunts, 15 fatal complications occurred that were directly related to the atrial catheter, resulting in an accumulated incidence of 3% of such serious side effects from VA shunting. Three of these 15 fatal cases presented with nonspecific signs of cardiopulmonary failure following 10-21 years' shunting, and they died from irreversible pulmonary hypertension within a few months. A fourth case of late cor pulmonale has done unexpectedly well and has improved considerably while receiving anticoagulant therapy for over a period of 3 years.

    Over the past several decades, work-related fatal incident reporting in China has become faster, more publicly accessible and, hence, a potentially more valuable process in support of the decision-making and enforcement actions of the government and safety professionals. A study was conducted to examine the characteristics of work-related fatalities in the People's Republic of China (PRC) available from the State Work Accident Briefing (SWAB) system. Injury incident records related to industries other than coal mining were downloaded from the SWAB system (April 2001 to March 2003). The findings were compared with a previously published regional work fatality study in China, data from the U.S. Census of Fatal Occupational Injuries, and estimates from the International Labor Organization (ILO). During the 2-year period, 1538 work-related events (7046 worker fatalities) were recorded. Collisions (25.6%), drownings (14.6%), and structural collapses (12.5%) were the most frequently reported fatal events. Collisions (24.5%) and falls (14.5%) were the most frequent causes of cited fatal events. Transportation (105.87 per 100 000); mining industries other than coal mining and quarrying (73.28); and electricity, gas, and water supply (14.88) were the industries with the highest estimated fatality rates. Generally, regions with lower economic activity reported more fatalities. The fatal injury rate estimated from the SWAB system was 4.80 per 100,000 (U.S. rate 4.00). ILO estimates for 1994 and 2002 were substantially higher than the estimates derived from the SWAB system. SWAB system differences with other data sources analyzed herein indicate that there remains room for system refinement. PMID:19401909

    Methyl and ethyl alcohol poisoning are still responsible for high morbidity and mortality rates. The purpose of this retrospective study was to examine ethyl and methyl alcohol poisoning related deaths in Ankara and surrounding cities between 2001 and 2011 and compare them with previous studied conducted in Turkey and other countries. For this purpose, 10,720 medico-legal autopsy cases performed in Ankara Branch of the Council of Forensic Medicine were reviewed in terms of alcohol poisonings. The deaths due to methanol and ethanol poisoning were 74 (0.69% of all medico-legal autopsies performed) and the distribution among them was 35 (47.3%) for methanol poisoning and 39 (52.7%) for ethanol poisoning. Overwhelming majority of the cases were male (n = 67, 90.5%). The mean age of the victims was 44.9 ± 10.9 years and ranging from 21 to 92 years. The age group of 35-49 years was the mostly affected. Most of the cases were seen in 2004 (n = 12, 16.2%). The levels of postmortem blood alcohol levels were available for all cases and the mean alcohol levels were 322.8 ± 155.5 mg/dL ranging from 74 to 602 mg/dL for methanol and 396.8 ± 87.1 mg/dL and ranging from 136 to 608 mg/dL for ethanol. Early diagnosis is essential for successful treatment in methanol and ethanol poisoning. Besides increased awareness, more sensitive/specific diagnostic tools, and the prompt approach to the poisoned individual should be implemented in the hospitals. PMID:23472793

  17. Measurement and dimension of road fatality in Brunei.

    2011-03-01

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

    From August to December of the year 2000 we ascertained 7 rapid deaths because of acute intoxication with tablets colloquially called Ufo. There were five men and two women aged from 20 to 29 (average 24) years. Analytic tests showed that one tablet of Ufo contains 40 mg of paramethoxyamphetamine, 1.0 mg of amphetamine, 0.05 mg of methamphetamine, 0.03 mg of 3-4-methylenedioxymethamphetamine. The levels of paramethoxyamphe-tamine in the blood of the deceased, determined by gas chromatography, were from 0.68 to 10.0 (approx. 3.2) mg/L and in the urine from 16 to 64 (approx. 35) mg/L. The press and television campaign caused elimination of fatal intoxications with parametoxy-amphetamine during the last 13 months. PMID:12184013

    OBJECTIVES:This study examined employment patterns of African-American and White workers and rates of unintentional fatal injuries, METHODS: Medical examiner and census data were used to compare occupational fatality rates for African Americans and Whites in North Carolina and to adjust for racial differences in employment patterns. RESULTS: African Americans' occupational fatality rate was higher by a factor of 1.3 to 1.5. Differences in employment structure appear to explain much of this disparity. However, the fatality rate for African-American men would have been elevated even if they had had the same employment patterns as White men. CONCLUSIONS: inequalities in access to the labor market, unequal distribution of risk within jobs, and explicit discrimination are all potential explanations for racial disparities in occupational injury mortality. These conditions can be addressed through a combination of social and workplace interventions, including efforts to improve conditions for the most disadvantaged workers. PMID:9584031

    Fatal familial insomnia has recently enlarged the group of prion diseases. The disease starts between 35 and 60 years of age, is inherited as an autosomic dominant trait, and leads to death within 7 to 32 months. Clinical symptoms and signs include insomnia dysautonomia, cognitive and motor alteration. The discrete topography of the lesions in fatal familial insomnia underlines the role of the thalamus in the regulation of the sleep-wake cycle. Atrophy, neuronal loss and gliosis are prominent in the anterior and dorsomedial nuclei of the thalamus. Spongiosis, which is usually found in prion diseases, is absent in fatal familial insomnia. An abnormal prion protein (PrPsc) is detected in the brain. There is a mutation at codon 178 of the gene encoding this protein. Fatal insomnia is distinct from Creutzfeldt-Jakob disease on clinical, histopathologic and molecular grounds. It provides new information about genetics of prion diseases which share the characteristics of being altogether inherited and, in most cases, transmissible. The recent finding of abnormal PrP in diffuse subcortical gliosis suggests that other degenerative disorders could actually be prion diseases.

    Balamuthia mandrillaris, a free-living ameba, causes rare but frequently fatal granulomatous amebic encephalitis (GAE). Few patients have survived after receiving experimental drug combinations, with or without brain lesion excisions. Some GAE survivors have been treated with a multi-drug regimen including miltefosine, an investigational anti-leishmanial agent with in vitro amebacidal activity. Miltefosine dosing for GAE has been based on leishmaniasis dosing because no data exist in humans concerning its pharmacologic distribution in the central nervous system. We describe results of limited cerebrospinal fluid (CSF) and serum drug level testing performed during clinical management of a child with fatal GAE who was treated with a multiple drug regimen including miltefosine. Brain biopsy specimens, CSF, and sera were tested for B. mandrillaris using multiple techniques, including culture, real-time polymerase chain reaction, immunohistochemical techniques, and serology. CSF and serum miltefosine levels were determined using a liquid chromatography method coupled to tandem mass spectrometry. The CSF miltefosine concentration on hospital admission day 12 was 0.4 μg/mL. The serum miltefosine concentration on day 37, about 80 h post-miltefosine treatment, was 15.3 μg/mL. These are the first results confirming some blood-brain barrier penetration by miltefosine in a human, although with low-level CSF accumulation. Further evaluation of brain parenchyma penetration is required to determine optimal miltefosine dosing for Balamuthia GAE, balanced with the drug's toxicity profile. Additionally, the Balamuthia isolate was evaluated by real-time polymerase chain reaction (PCR), demonstrating genetic variability in 18S ribosomal RNA (18S rRNA) sequences and possibly signaling the first identification of multiple Balamuthia strains with varying pathogenicities.

    Rotenone is a neurotoxin derived from Derris roots or yam bean of genus Derris or Lonchocarpus It is known to cause Parkinson-like symptoms and is a potent electron transport inhibitor. Rotenone was detected in postmortem specimens in a fatal case of rotenone poisoning with an organic pesticide by liquid chromatography-tandem mass spectrometry with an information-dependent acquisition and MS-MS library search. The forensic specimens were prepared by solid-phase extraction with a Bond Elut(®) Certify cartridge. The mobile phase comprised 5 mM ammonium formate in 10% methanol and 5 mM ammonium formate in 90% methanol. The assay was linear over the range from 0.01 to 1.0 mg/L (r(2) = 0.995). The limit of detection and quantitation in the blood were 0.001 mg/L (signal-to-noise, S/N = 3) and 0.003 mg/L (S/N = 10), respectively. The intraday accuracy and precision for rotenone that were determined by five replicates at 0.02, 0.10 and 1.0 mg/L in blood were <15.0% of bias and <9.0% of CV, respectively. The interday accuracy and precision for rotenone that were determined by seven replicates at 0.02, 0.10 and 1.0 mg/L in blood were <18.0% of bias and <17.0% of CV, respectively. Relative recovery with 0.02, 0.1 and 1.0 mg/L in blood was 104.2, 103.3 and 81.6% (n = 6), respectively. The described method was applied for the determination of rotenone in a fatal case of intoxication of a 33-year-old man who was found dead on a bed in a temporary house. In this case study, the concentrations of rotenone in heart blood (HB), peripheral blood (PB), gastric contents and vitreous humor were 0.77 mg/L, 0.02 mg/L, 126.4 mg/kg and 0.003 mg/L, respectively. The rotenone concentration ratio of the HB/PB was 38.8 and that of gastric contents/PB was 6412.3, suggesting a massive ingestion of rotenone with postmortem redistribution. This study is the report of rotenone detection in a fatal case with the ingestion of the organic insecticide containing rotenone. PMID:27197984

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

    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 < 0.01). 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.

    Scuba divers' pulmonary oedema (SDPE) is an increasingly recognised disorder in divers. We report three fatal cases of SDPE, demonstrating its potential serious nature even in the absence of underlying cardiac disease demonstrable clinically or at autopsy. This, together with the frequency of recurrences, has implications on assessing fitness for subsequent diving, snorkelling and swimming. The differential diagnosis of this disorder is also considered, as is its possible inducement by salt water aspiration and its relationship to drowning.

    There is a paucity of research analysing the influence of fiscal decentralisation on health outcomes. Colombia is an interesting case study, as health expenditure there has been decentralising since 1993, leading to an improvement in health care insurance. However, it is unclear whether fiscal decentralisation has improved population health. We assess the effect of fiscal decentralisation of health expenditure on infant mortality rates in Colombia. Infant mortality rates for 1080 municipalities over a 10-year period (1998-2007) were related to fiscal decentralisation by using an unbalanced fixed-effect regression model with robust errors. Fiscal decentralisation was measured as the locally controlled health expenditure as a proportion of total health expenditure. We also evaluated the effect of transfers from central government and municipal institutional capacity. In addition, we compared the effect of fiscal decentralisation at different levels of municipal poverty. Fiscal decentralisation decreased infant mortality rates (the elasticity was equal to -0.06). However, this effect was stronger in non-poor municipalities (-0.12) than poor ones (-0.081). We conclude that decentralising the fiscal allocation of responsibilities to municipalities decreased infant mortality rates. However, this improved health outcome effect depended greatly on the socio-economic conditions of the localities. The policy instrument used by the Health Minister to evaluate municipal institutional capacity in the health sector needs to be revised. PMID:22417812

    Granulomatous amebic encephalitis (GAE) from Balamuthia mandrillaris, a free-living ameba, has a case fatality rate exceeding 90% among recognized cases in the United States. In August 2010, a GAE cluster occurred following transplantation of infected organs from a previously healthy landscaper in Tucson, Arizona, USA, who died from a suspected stroke. As B. mandrillaris is thought to be transmitted through soil, a serologic survey of landscapers and a comparison group of blood donors in southern Arizona was performed. Three (3.6%) of 83 serum samples from landscapers and 11 (2.5%) of 441 serum samples from blood donors were seropositive (p = 0.47). On multivariable analysis, county of residence was associated with seropositivity, whereas age, sex, and ethnicity were not. Exposure to B. mandrillaris, previously unexamined in North America, appears to be far more common than GAE in Southern Arizona. Risk factors for disease progression and the ameba's geographic range should be examined. PMID:24458652

    Objectives—To compare the extent, distribution, and nature of fatal occupational injury in New Zealand, Australia, and the United States. Setting—Workplaces in New Zealand, Australia, and the United States. Methods—Data collections based on vital records were used to compare overall rates and distribution of fatal injuries covering the period 1989–92 in Australia and the United States, and 1985–94 in New Zealand. Household labour force data (Australia and the United States) and census data (New Zealand) provided denominator data for calculation of rates. Case definition, case inclusion criteria, and classification of occupation and industry were harmonised across the three datasets. Results—New Zealand had the highest average annual rate (4.9/100 000), Australia an intermediate rate (3.8/100 000), and the United States the lowest rate (3.2/100 000) of fatal occupational injury. Much of the difference between countries was accounted for by differences in industry distribution. In each country, male workers, older workers, and those working in agriculture, forestry and fishing, in mining and in construction, were consistently at higher risk. Intentional fatal injury was more common in the United States, being rare in both Australia and New Zealand. This difference is likely to be reflected in the more common incidence of work related fatal injuries for sales workers in the United States compared with Australia and New Zealand. Conclusions—The present results contrasted with those obtained by a recent study that used published omnibus statistics, both in terms of absolute rates and relative ranking of the three countries. Such differences underscore the importance of using like datasets for international comparisons. The consistency of high risk areas across comparable data from comparable nations provides clear targets for further attention. At this stage, however, it is unclear whether the same specific occupations and/or hazards are contributing to

    The smoking cessation agent varenicline acts as a partial agonist on α(4)β(2) nicotinic acetylcholine receptors. Although debated, several reports have linked varenicline therapy to an increased risk of suicidal thoughts and/or suicide. In addition, several non-fatal overdose cases have been reported. In this report, we utilised a sample preparation procedure suitable for postmortem samples and gas chromatography coupled to mass spectrometry to analyse samples obtained from a suicidal case in which ingestion of an overdose of varenicline had occurred. Extremely high concentrations of varenicline (>250 ng/ml) were detected in the blood of the deceased, in addition to high concentrations in urine and vitreous humour. To the best of our knowledge, similar high concentrations have not been reported yet. Although, with respect to the mechanism of death in this case, confounding factors were concomitant ethanol consumption and, importantly, potentially fatal hypothermia, this is the first report of a fatality associated with the ingestion of an overdose of varenicline.

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

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

    The effects of business cycles on health outcomes in general, and on traffic fatalities in particular, have received much attention recently. In this paper, we focus on motorcycle safety and examine the impact of changing levels of economic activity on fatal crashes by motorcyclists in the United States. We analyze state-level longitudinal data with 1,104 state/year observations from the 1988-2010 Fatality Analysis Reporting System (FARS). Using the extensive motorcycle crash characteristics available in FARS, we examine not only total fatality rates but also rates decomposed by crash type, day, time, and the level of the motorcycle operator's blood alcohol content. Our results are consistent with much of the existing literature showing that traffic fatality rates are pro-cyclical. The estimates suggest that a 10% increase in real income per capita is associated with a 10.4% rise in the total motorcycle fatality rate. Along with potential mechanisms, policymakers and public health officials should consider the effects of business cycles on motorcycle safety. PMID:24581077

  17. An empirical model for global earthquake fatality estimation

    2010-01-01

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

    Cyanohydrins, also be called cyanoalcohols, are important industrial precursors to carboxylic acids and some amino acids. Acetone cyanohydrin (ACH) and formaldehyde cyanohydrin (glycolonitrile, FCH), which are the typical examples of cyanohydrins, are classified as extremely hazardous substances. As the cyanohydrins can readily decompose, and it is hard to find cyanohydrins in gastric contents and heart blood, the determination study in biological samples can be divided into two parts: the first is the determination of HCN by using a Prussian blue reaction and the HS-GC-MSD after derivatization by chloramine-T. The second is the determination of acetone or formaldehyde. In this part, headspace gas chromatography with flame ionization detector (HS-GC-FID) and solid phase microextraction (SPME)-gas chromatography with mass spectrometric detectors (GC-MSD) had been used. In this report, we reported two fatal intoxication cases of ACH and FCH; one person was killed by his wife by poisoning his food and the other was suicide by poison. Two real cases of ACH and FCH in human blood and gastric contents have been analyzed by using the above-mentioned method. The Prussian blue reaction was positive in the two cases. The peaks of acetone with retention times of 0.998 min appear in specimens of the deceased are consistent with the retention times of pure acetone. The peaks of formaldehyde with a retention time of 1.658 min appear in heart blood of the deceased, and the retention time of formaldehyde of the liquid is 1.674 min, which are consistent with the retention times of pure formaldehyde (1.673 min).

    Tranylcypromine (TCP) is a non-selective and irreversible monoamine oxidase inhibitor and an effective agent in the treatment of major depression. It features a complex pharmacologic profile and overdoses might induce severe intoxications. To identify typical clinical presentations of TCP-intoxications, range of associated TCP-dosages and possible differences between fatal and non-fatal intoxications a systematic review of all previously published cases of TCP-intoxications was conducted. We detected n=20 reports of TCP-intoxications in the literature (fatalities n=10). Mean age was 36.7 years (median 37); the majority of patients were female (60%). Frequent findings in patients with TCP-intoxications were disturbance of consciousness/cognitive dysfunction (90%), cardio-vascular symptoms (55%), hyperthermia (50%), respiratory distress (45%), delirium (45%), muscular rigidity (30%) and renal failure (20%). Suicidal intent was present in n=18 (90%) patients. First clinical symptoms related to TCP-intoxication developed on average in less than 1 day. The average dosage related to TCP-intoxication was 677 mg. The highest survived TCP-dosage was 4000 mg and the lowest fatal dosage was 170 mg. Patients with fatal intoxications were on average older (40.5 vs. 32.8 years) and developed a more rapid onset of symptoms (0.2 vs. 0.8 days). Death occurred after a mean time of 0.6 days; symptom relief in patients with non-fatal intoxications developed on average after 3.2 days. Considering the large dose spectrum between survived and lethal TCP-dosages individual susceptibility factors might play a role regarding the severity of clinical symptoms independently of the ingested dosage.

    Among the new psychoactive substances encountered in forensic investigations is the opioid, acetyl fentanyl. The death of a 28-year-old man from recreational use of this compound is reported. The decedent was found in the bathroom of his residence with a tourniquet secured around his arm and a syringe nearby. Postmortem examination findings included marked pulmonary and cerebral edema and needle track marks. Toxicological analysis revealed acetyl fentanyl in subclavian blood, liver, vitreous fluid, and urine at concentrations of 235 ng/mL, 2400 ng/g, 131 ng/mL, and 234 ng/mL, respectively. Acetyl fentanyl was also detected in the accompanying syringe. Death was attributed to recreational acetyl fentanyl abuse, likely through intravenous administration. The blood acetyl fentanyl concentration is considerably higher than typically found in fatal fentanyl intoxications. Analysis of this case underscores the need for consideration of a wide range of compounds with potential opioid-agonist activity when investigating apparent recreational drug-related deaths.

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

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

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

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

The outbreaks occurred in Northern California (Yolo County), Southern California (Kern County), and North Carolina (Guilford County). An estimation of the affected population is >150 cats among 3 affected shelters, with a mortality rate of up to 30%. Among 20 cats submitted for necropsy there were 2 distinct pathologic presentations. The first (shelters 1 and 2) was skin ulceration and chronic respiratory infection that progressed, in some cats, to necrotizing sinusitis and meningitis. The second (shelter 3) was rapid progression from necrotizing fasciitis with skin ulceration to toxic shock-like syndrome, sepsis, and death. S canis was the sole pathogen identified in most cases. Whether hypervirulent S canis strains exist is unknown; there is little understanding of how these bacteria cause invasive disease in cats.

    Farm-related fatalities in Australia were studied as part of a larger study of all work-related traumatic fatalities from 1989-1992. Information concerning 373 unintentional work-related fatalities was obtained from inspection of coronial files and described. The fatality rate per 100,000 workers was four times higher for agricultural industry workers (20.6) compared to the all-industry rate during the same time frame (5.5). Males comprised 95% of all agricultural work-related deaths. Agents such as farm vehicles, mobile farm machinery (mainly tractors), and farm structures (mainly dams) were among the most common involved in the fatal incident. Being hit by moving objects, vehicle accidents, and rollovers of mobile machinery (mainly tractors) were among the most common mechanisms of fatal injury on farms. Transport for work purposes, working with animals, working with crops, and maintenance were the most common activities being undertaken. The information obtained from this study is being used to develop health and safety risk profiles for agricultural industries, and these profiles are being used in turn to develop guidance material for farmers, on-farm checklists, and other tools to help farmers manage their occupational health and safety risk.

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

    NASA Technical Reports Server (NTRS)

    Scheuring, RIchard

    2005-01-01

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

    A liquid chromatography-MS-MS turbulent flow on-line extraction method was developed for the determination of trimebutine (TMB) and its main active metabolite N-mono-desmethyltrimebutine (nortrimebutine or nor-TMB) in human plasma. After protein precipitation and internal standard (IS, haloperidol-d4) addition, 50 µL of the supernatant were transferred onto a Cyclone-Turbo-Flow extraction column followed by an Hypersil PFP Gold analytical column. Detection was carried out on a triple quadrupole tandem mass spectrometer using positive electrospray ionization. The transitions used were m/z 388.0→343.0, 374.0→195.0 and 380.1→169.0 for TMB, nor-TMB and IS, respectively. The method was validated over the concentration range of 10-1,000 ng/mL for both compounds. The accuracy evaluated at three concentrations was within 90.0-98.5% and the intra- and interday coefficient of variation's for the two molecules were <8.7%. The method was applied to a toxicokinetic study of a self-poisoning case with TMB in a 19-old girl. The concentration of TMB decreased from 747 to 77 ng/mL, while nor-TMB decreased from 9,745 to 205 ng/mL after 5 days and the fatal issue. This case confirms the literature underlining the potential toxicity of TMB, which has long time been considered as a harmless molecule. PMID:26342056

    Background Leptospirosis is a potentially fatal bacterial zoonosis that is endemic throughout the tropics and may be misdiagnosed as dengue. Delayed hospital admission of leptospirosis patients is associated with increased mortality. Methodology/Principal Findings During a concurrent dengue/leptospirosis epidemic in Puerto Rico in 2010, suspected dengue patients that tested dengue-negative were tested for leptospirosis. Fatal and non-fatal hospitalized leptospirosis patients were matched 1:1–3 by age. Records from all medical visits were evaluated for factors associated with fatal outcome. Among 175 leptospirosis patients identified (4.7 per 100,000 residents), 26 (15%) were fatal. Most patients were older males and had illness onset during the rainy season. Fatal case patients first sought medical care earlier than non-fatal control patients (2.5 vs. 5 days post-illness onset [DPO], p < 0.01), but less frequently first sought care at a hospital (52.4% vs. 92.2%, p < 0.01). Although fatal cases were more often diagnosed with leptospirosis at first medical visit (43.9% vs. 9.6%, p = 0.01), they were admitted to the hospital no earlier than non-fatal controls (4.5 vs. 6 DPO, p = 0.31). Cases less often developed fever (p = 0.03), but more often developed jaundice, edema, leg pain, hemoptysis, and had a seizure (p ≤ 0.03). Multivariable analysis of laboratory values from first medical visit associated with fatal outcome included increased white blood cell (WBC) count with increased creatinine (p = 0.001), and decreased bicarbonate with either increased WBC count, increased creatinine, or decreased platelet count (p < 0.001). Conclusions/Significance Patients with fatal leptospirosis sought care earlier, but were not admitted for care any earlier than non-fatal patients. Combinations of routine laboratory values predictive of fatal outcome should be considered in admission decision-making for patients with suspected leptospirosis. PMID:26914210

    The treatment of measles pneumonitis in immunocompromised adults is not established. We describe a patient with Hodgkin's lymphoma who developed acute pneumonia during a measles infection. On day 13, intravenous ribavirin and immunoglobulins were administrated. On day 18, the patient developed acute respiratory failure. An examination of transbronchial pulmonary biopsies showed Warthin-Finkeldey giant cells that are pathognomonic of measles pneumonitis. The patient died despite aggressive supportive care. Our case and a review of literature show that measles pneumonitis is routinely fatal in patients with cancer. We suggest that antiviral drugs should be considered as soon as the diagnosis has been established.

    The first recorded automobile fatality occurred in a small town in the Irish Midlands in 1869. Mary Ward, a celebrated microscopist, artist, astronomer and naturalist, fell from a steam carriage and died after crush injuries from its heavy iron wheels. The story of first automobile fatality characterizes the individual tragedy that is each premature death. It also illuminates the story of a remarkable Victorian scientific family. Among their many achievements was the building of a reflector telescope in the heart of rural Ireland that was the largest in the world for 74 years.

    An investigation by a Naval Board of Inquiry into the circumstances of a fatal naval diving accident is presented. Although drowning contributed to the fatal outcome, massive arterial gas embolism is thought to have been the principal cause of death, and the value of post-mortem computed tomography scanning for its detection is demonstrated. The possibility is discussed of diver error due to unfamiliarity with equipment and procedures, compounded by nitrogen narcosis. The shortfall in expertise of coronial inquiries into diving deaths is emphasized against a background of increasing popularity of sports diving around Australia. The implications for the offshore industry are obvious and suggest the need for a federal diving inspectorate.

    In 2008, the work-related injury fatality rate was 3.8 per 100,000 workers in the United States but was 5.2 per 100,000 workers for the southeast region. Work-related fatalities in the southeast were examined for the period 2008 to 2011. Median work-related injury fatality rates are reported for the southeast region, each of the 12 states, and the United States. The percentages of employees in high fatality industries and work-related fatalities by cause were calculated. Finally, the Occupational Safety and Health Administration's database was searched for fatality reports. States with the highest rates (per 100,000 workers) included Arkansas (7.2), Louisiana (6.8), and West Virginia (6.6). Arkansas, Louisiana, Mississippi, and West Virginia each had more than 20% of their employees in high fatality industries. Forty percent of work-related injury fatalities were from transportation incidents in the southeast and the United States. Future analyses should include work-related injury fatality rates by industry and compare rates with other U.S. regions. PMID:26467194

  19. The case of the elusive infant mortality rate.

    PubMed

    Hartford, R B

    1984-05-01

    The layperson's concern focuses on 4 criteria for comparabiltiy of infant mortality data: appropriateness of unit of analysis, whether or not the population measured is a certain minimum size or conforms to some social or demographic standard; completeness, i.e., the extent to which all relevant are counted; coverage -- the extent to which all population segements or subgroups are included in the registration system within a country; and uniformity of measurement, that is, use of standard definitions and measurement procedures. A year ago Carl Haub's article, "Where Does the U.S. Stand in Infant Mortality," ranked the US 19th in a comparison with 30 other countries. Following UN practice, Haub excluded countries reporting less than 50 infant deaths, whose rates might be easily skewed. Completeness of registration was not a problem in highly industrialized nations with highly developed medical care and statistics recording systems. In recent years coverage has been essentially comprehensive. It is with the uniformity of measurement that complications arise -- in discriminating between a fetal death and an infant death. The UN standard lists 4 life signs for an infant, any one of which constitutes a live birth. Other countries have had a shorter list of admissible signs. Still other countries have excluded infants dying within 24 hours of birth or set viability criteria for including newly born in the infant category. Yet, the statistics in many cases have become standardized. Regarding the objection that the US with its large mixed population cannot be compared with small European countries, 10 states of the US with the lowest infant mortality rates in 1980 are examined. They are: New Hampshire (9.2); Wyoming (9.8); Vermont (9.9); Minnesota (10.0); Colorado (10.1); Wisconsin (10.3); Hawaii (10.3); Kansas (10.4); Utah (10.4); and Massachustetts (10.5). The populations of most of these states are small and homogeneous. If these states were to be inserted into Haub

    OBJECTIVES: This study examined the relationship between changes in employment in North Carolina in the 1980s and fatal occupational injury rates. METHODS: Unintentional fatal occupational injuries (n = 1989) in North Carolina between 1978 and 1991 were identified via the medical examiner's system. RESULTS: Overall fatal injury rates declined during the 1980s, but rates increased 9.6% per year among manufacturing industries that declined in employment size; rates fell among service sector and manufacturing industries that grew. CONCLUSIONS: Increasing occupational fatal injury rates accompanied the decline in workforce in North Carolina's traditional, labor-intensive manufacturing industries during the 1980s, while service sector and expanding manufacturing industries have experienced declining fatal injury rates.

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

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

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

    Workers aged 65 and older had a workplace fatality rate of 2.6 times that of workers aged 16 to 64 for 1980 through 1991 (14.1 per 100,000 vs 5.4), according to National Traumatic Occupational Fatalities (NTOF) data. The highest rates were in mining, agriculture, and construction. Compared with younger workers, older men were at an elevated risk for fatalities caused by machines, and older women for fatal falls and homicide. Prevention efforts should focus on older workers in agricultural settings, as well as those at increased risk of workplace falls or violence.

    A fatal case of Physalia physalis (Portuguese man-o'-war) envenomation occurred on the Florida Atlantic coast in 1987. Despite appropriate beachside first aid, the patient was conscious only several minutes before having primary respiratory arrest and, later, cardiovascular collapse that resulted in death. Discharged nematocysts were still visible on the injured stratum corneum five days after envenomation. Additional treatment maneuvers suggested by this case include testing the tentacle fragments found on the victim's skin before their removal to ensure that nematocyst firing has been counteracted. We document the first human fatality caused by P physalis envenomation. PMID:2564268

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

    PubMed

    2015-01-01

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

    Anaphylaxis implies a risk of death even in patients whose prior episodes have been considered mild and managed easily. Anaphylaxis occurs in all age groups, from infants to the elderly, but most deaths occur in adults. Factors or circumstances associated with near-fatal or fatal anaphylaxis are reviewed from the following 10 perspectives: accidents and mishaps, adulterated products, age, allergens, atopy, comorbidities, Munchausen syndrome or contrived anaphylaxis, patient factors, route of administration, and treatment-related issues. There are no absolute contraindications to self-injectable epinephrine, and epinephrine can be administered for anaphylaxis to elderly patients or to those patients receiving beta-adrenergic blockers.

    1997-09-01

    A death certificate-based surveillance system was used to identify 2144 work-related motor vehicle fatalities among civilian workers in the United States construction industry over the years 1980-92. Construction workers were twice as likely to be killed by a motor vehicle as the average worker, with an annual crude mortality rate of 2.3/100,000 workers. Injury prevention efforts in construction have had limited effect on motor vehicle-related deaths, with death rates falling by only 11% during the 13-year period, compared with 43% for falls, 54% for electrocutions and 48% for machinery. In all industries combined, motor vehicle fatality rates dropped by 47%. The largest proportion of motor vehicle deaths (40%) occurred among pedestrians, with construction accounting for more than one-fourth of all pedestrian deaths. A minimum of 54 (6%) of these pedestrian fatalities were flaggers or surveyors. Flaggers accounted for half the 34 pedestrian fatalities among women, compared with only 3% among men. Along with previous studies and recent trends in the amount and type of road construction, these results underscore the need for better traffic control management in construction work areas to reduce pedestrian fatalities. As the second leading cause of traumatic death in construction, with an annual average share of 15% of the total deaths, exceeded only by falls, prevention of work-related motor vehicle research should become a greater priority in the construction industry.

    A 58-year-old man was submitted to our intensive care ward with respiratory failure due to pneumonitis. He had previously been treated for non-Hodgkin lymphoma by autologous stem cell transplantation, as a result of which bone marrow function was reduced. Further analysis showed infection with new influenza A(H1N1); typing revealed an oseltamivir-resistant subpopulation (H275Y). The patient was treated with oseltamivir and intravenously with zanamivir, but died of respiratory disease progression. This is the first published case of oseltamivir-resistant new influenza A(H1N1) infection in the Netherlands. PMID:20482913

    A 27-year-old man suddenly died in hospital of acute respiratory distress syndrome secondary to severe systemic vasculitis. Multi-phase post-mortem computed tomography angiography followed by scientific autopsy of the thoracic and abdominal cavity and histology was performed, illustrating the advantages and drawbacks of such techniques. Imaging enabled us to examine the cranium, as the family refused cerebral dissection. MPMCTA revealed absence of opacification of the left middle cerebral artery. But parenchymal findings of thoracic and abdominal organs were still difficult to interpret after both imaging and macroscopic examination during the autopsy. Microscopic examination provided the definitive diagnosis of cause of death. Analysis revealed systemic vasculitis of the lung complicated by diffuse alveolar, mediastinal, splenic and retroperitoneal lesions. We were unable to determine the type of vasculitis, whether polyarteritis nodosa or microscopic polyangiitis, because of artifactual glomerular collapse. We observed some structural changes in tissue secondary to contrast agent injection, affecting the vascular system and renal parenchyma in particular. Such artifacts must be known in order to avoid misinterpreting them as pathological findings. MPMCTA and conventional autopsy are two complementary techniques showing both their specific advantages and limits which have to be known in order to choose the appropriate technique. One limit of both techniques is the detection of microscopic findings which can only be obtained by additional histological examination. This case report underlines this fact and demonstrates that caution is required in some cases if microscopic analyses are carried out after contrast agent injection.

    OBJECTIVES: To assess rates and patterns of agricultural machinery injuries in farm children in order to both determine priorities and develop strategies for injury control in this population. METHODS: Coroners' files and hospital discharge data were examined for Ontario farm children aged 0-19 who had agricultural machinery injuries over a five year period ending 31 March 1990. Injury rates were described by age, sex, geographic region, type of machinery, and mechanism of injury. Common patterns of injury deserving of priority for prevention were then identified and described. RESULTS: 283 machinery injuries to children were identified. Injury rates were 116 and 25/100,000/year for boys and girls respectively. Boys were at increasing risk relative to girls as their ages increased. Young children were at greatest risk for fatal injury. There is a prominent summer peak in occurrence. The farm tractor was the machine most commonly associated with these injuries (33.2%), and entanglement, usually of clothing, was the mechanism cited most often (36.3%). The case fatality ratio (ratio of hospitalizations:deaths) was generally low whether assessed by machinery type or by mechanism of injury. This provides an indication of the lethality of these injuries. Common patterns associated with injury risk included: (1) inadequate supervision of small children; (2) permitting children to be in the area of moving or unguarded machinery; (3) allowing children to accompany workers using farm machinery; and (4) having children performing work related tasks inappropriate for their age. CONCLUSIONS: Machinery related injuries are not uncommon in farm children and have a high case fatality rate. These rates changed little over the five year study period. Feasible strategies for prevention of these injuries, four of which are presented here, need to be developed and implemented by public health professionals working in cooperation with members of the agricultural industry.

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

    Sudden death due to inhalation of aliphatic hydrocarbons such as butane and propane is well described in the literature. The main mechanism involved is the induction of a fatal cardiac arrhythmia. This phenomenon is frequently associated with prisoners who accidentally die while sniffing these volatile substances with an abuse purpose. Furthermore, such prisoners are often under psychiatric treatment; specific drugs belonging to this pharmacological class lead to a drug-related QT interval prolongation, setting the stage for torsade de pointes. In this article, we present the case of a prisoner died after sniffing a butane-propane gas mixture from a prefilled camping stove gas canister. The man was under psychiatric drugs due to mental disorders. He was constantly subjected to electrocardiogram to monitor the QTc (corrected QT interval), which was 460 milliseconds long. Toxicological analysis on cadaveric samples was performed by means of gas chromatography (head space) and revealed the presence of butane and propane at low levels. The aim of this article was to discuss a possible arrhythmogenic interaction of QT interval prolongation induced by psychiatric drugs and butane-propane inhalations, increasing the cardiovascular risk profile. In other words, evidence may suggest that prisoners, under these circumstances, are more likely to experience cardiovascular adverse effects. We believe that this study underlines the need to take this hypothesis into account to reduce death risk in prison and any medical-related responsibilities. Further studies are needed to validate the hypothesis.
