Scuba diving-related fatalities in the Philippines from 2008 to 2022 as reported in online news media.

The present study aims to investigate the demographics and characteristics of scuba diving fatalities in the Philippines which can help in the identification of local trends and ultimately in the development of appropriate preventive measures. Data on scuba diving-related fatalities in the Philippines from 2008 to 2022 were manually retrieved from online news media sources. Information on age, sex, nationality, certification, purpose, and causative factors, whenever possible were collected and analysed. A total of 39 fatalities were identified having a median age of 43.5 (range 20-80). Majority of victims were males (n = 30), and of foreign ethnicity (n = 26). Asphyxia was identified as the possible disabling injury in almost half of the cases (n = 17). The causes of death based on autopsies were determined only for few cases which included drowning (n = 2), heart attack (n = 1), and traumatic injuries from a dynamite blast (n = 1). Potential vulnerable groups were identified to be the ageing population and foreign tourist divers. In the absence of an existing database, this preliminary report provides the best available evidence at this time concerning scuba diving fatalities in the Philippines.

Suicide mortality according to occupation and method of suicide, Massachusetts, 2010-2019.

BACKGROUND: Suicide rates in the United States have been increasing. Work-related factors may contribute to risk for suicide. These work-related factors may be reflected in a varied risk for different suicide methods between occupations. This study sought to assess occupational differences in suicide rates according to the method used. METHODS: Death certificate data about suicide deaths in Massachusetts between 2010 and 2019 were used to calculate mortality rates and rate ratios with univariable and multivariable models controlling for age, sex, race ethnicity, and educational attainment for suicides overall, and for three specific methods of suicide (hanging/strangulation/suffocation, firearms, and poisoning) by occupation. RESULTS: In multivariate models, the risk for suicide was significantly elevated for workers in arts, design, entertainment, sports, and media (relative risk [RR] = 1.84, 95% confidence interval [CI] = 1.53, 2.22); construction trades (RR = 1.68, 95% CI = 1.53, 1.84); protective services (RR = 1.49, 95% CI = 1.26, 1.77); and healthcare support occupations (RR = 1.55, 95% CI = 1.25, 1.93). Occupational risk for suicide differed across different methods. For hanging/strangulation/suffocation, workers in arts, design, entertainment, sports, and media occupations had the highest RR (2.09, 95% CI = 1.61, 2.71). For firearms, workers in protective service occupations had the highest RR (4.20, 95% CI = 3.30, 5.34). For poisoning, workers in life, physical, and social science occupations had the highest RR (2.32, 95% CI = 1.49, 3.60). CONCLUSIONS: These findings are useful for identifying vulnerable working populations for suicide. Additionally, some of the occupational differences in the risk for suicide and for specific methods of suicide may be due to workplace factors. Further research is needed to understand these workplace factors so that interventions can be designed for prevention.

A special type of homicide-suicide: A retrospective study of the characteristics of extended suicide.

Extended suicide, a specific type of homicide-suicide event, has severe social consequences yet remains lacking systematic research. This retrospective study investigated 51 cases of extended suicide involving mental disorders in central China with aim of better understanding risk factors for such events and guiding prevention strategies. Over an 8-year period from 2015 to 2022, cases were collected from forensic institutions, and demographic characteristics, case details, and psychiatric data were recorded. The 51 incidents involved 51 perpetrators and 79 victims, with more female perpetrators (58.8%) and more female victims (54.4%). The average age of the perpetrators was 36.1, and most were married (88.2%). Almost all of the victims were family members of the perpetrator, like the most numerous children (64.6%), followed by spouses (24.1%). The most common homicide mode of death was mechanical asphyxia (38.0%), followed by sharp devices (36.7%) and drug poisoning (16.5%). Depressive disorders (76.5%) were the most common diagnosis of mental disorder for perpetrators. The study analyzed the unique characteristics of extended suicide to enrich such data. These findings help strengthen the screening and identification of potential perpetrators and victims to prevent such cases from occurring.

Demographic analysis of the suicide method by gender and age of the deceased between 2001 and 2010. / Analiza demograficzna metody samobójstwa z uwzglednieniem plci oraz wieku zmarlych w latach 2001-2010.

Aim: AAnalysis of the choice of suicide method by gender and age of the deceased. Material and methods: The study presented here was based on a retrospective analysis of autopsy reports from the years 2001-2010 in the Department of Forensic Medicine of the Jagiellonian University Collegium Medicum in Kraków. The basis of the research work conducted was the collection and extensive analysis of cases of suicide deaths. Subsequently, a preference analysis of the choice of suicide method was conducted, taking into account the age and gender of the deceased. The statistical analysis performed used logistic regression in Excel's XLSTAT as an analysis tool. Results: A total of 2,073 suicide cases were collected from the time frame under discussion. The predominant method of suicide was hanging (1524 cases, 1329 men and 195 women), the second most common method was jumping from the roof or window of a high floor of a building (jumping from heights; 171 cases, 100 men, 71 women). A statistically significant correlation of suicide method with gender was found for: hanging [odds ratio (OR) male (M) vs. female (F) = 3. 4; confidence interval (CI) = 2.7-4.3; p0.001]; drowning [OR: M/F =4.1; CI = 2.6-6.4; p0.001]; jumping from heights [OR: M/F=4.1; CI=2.9-5.7; p0.001] and poisoning [OR: M/F=3.2; CI = 2.1-4.9]. Suicide with the use of firearms occurred exclusively in the case of men (40 cases). The age of the victims correlated with the method of committing suicide by jumping from heights [0R=0.98; CI=0.97-0.99; p0.001] and rail suicide [OR=0.98; CI=0.96-0.99; p0.001]. Conclusions: The study revealed that both age and gender have a significant impact on the choice of suicide method. According to available epidemiological data and the authors' predictions, a predominance of male over female sex was observed in the case of hanging, while jumping from heights was relatively more often chosen by women. The elderly were less likely to choose jumping from heights and rail suicide.

Relationships between cardiovascular signs and neurological signs in asphyxiated neonates in Ilorin, North Central Nigeria.

BACKGROUND: Perinatal asphyxia is a condition associated with multiple organ dysfunctions inclusive of cardiovascular dysfunction. Neurologic predictors of survival have been studied, but little has been reported regarding cardiovascular signs and their role in determining outcome in asphyxia. OBJECTIVE: The study aimed to determine the relationship between cardiovascular signs and outcomes in asphyxiated newborns with hypoxic ischaemic encephalopathy. METHODS: This was a cross sectional study involving asphyxiated new-born babies recruited within the first 24 hours of life. Hypoxic ischaemic encephalopathy staging was done using Sarnat and Sarnat staging. All patients had a detailed cardiovascular examination on admission, after initial resuscitation (30 - 60 minutes) into admission, and were followed till final outcome: discharge or death. RESULTS: Eighty-five asphyxiated new-borns with HIE were studied over seven months. Abnormal cardiovascular-related signs identified in the patients included respiratory distress (64.7%), small volume pulse (57.6%), hypotension (52.9%), hypoxemia (48.2%) and shock (32.9%). Five babies died. None of the clinical signs had a significant relationship with mortality. CONCLUSION: Abnormal cardiovascular signs increased with the progression of HIE staging but had no relationship with mortality.

Changes over time in means of suicide in Canada: an analysis of mortality data from 1981 to 2018.

BACKGROUND: Ongoing surveillance of the means of suicide is necessary for effective prevention. We examined how mortality rates owing to different means of suicide changed in Canada from 1981 to 2018. METHODS: We obtained data from 1981 to 2018 on suicide deaths of individuals aged 10 years and older, from the Canadian Vital Statistics Death Database. We used joinpoint regression analysis to examine changes over time in the suicide mortality rate for the 3 most common means of suicide. RESULTS: The age-standardized suicide mortality rate declined in earlier decades for both sexes, but did not significantly change in recent decades for either sex. The age-standardized rate of suicide by suffocation increased from 1993 for females (2.1% per year) and from 1996 for males (0.4% per year). The age-standardized rate of suicide by poisoning decreased for females (2.2% per year) and males (2.1% per year) from 1981 to 2018. The age-standardized rate of suicide by firearm decreased from 1981 to 2008 (7.4% per year) but did not significantly change there-after for females; for males, it decreased 2.1% per year from 1981 to 1993 and 5.7% per year from 1993 to 2007, but did not significantly change thereafter. INTERPRETATION: For both sexes, the rate of suicide by poisoning is decreasing, the rate of suicide by suffocation is increasing, and the rate of suicide by firearm has not significantly changed in the last decade. Given the high proportion of suicide deaths by suffocation, its increasing rate and the difficulty of restricting the means of suffocation, other approaches to suicide prevention are needed.

A forensic analysis on 53 cases of complex suicides and one complicated assessed at the Bureau of Legal Medicine of Milan (Italy).

Complex suicides are highly uncommon suicides in which multiple detrimental methods are used simultaneously or in chronological succession. We retrospectively analyzed through our database the 25512 autopsy reports registered at the Bureau of Legal Medicine of Milan in the last 27 years from 1993 until 2019, where 4498 suicides were documented. We assessed 53 cases of complex suicides and only one case of complicated suicide: for all of them we analyzed both data collected during the on-site investigation and the autopsy. In our case series, we identified a total number of 113 methods chosen and variably combined by the victims, which were classified into 17 categories. On the whole the most frequent association of suicide methods resulted in the combination of the plastic bag suffocation with inert gas inhalation (13 out of 53 complex suicides; 24.5%). We also analyzed our cases of simple suicides (1993-2019), to compare them with the complex suicides. In this study, we present a complete analysis regarding our cases of complex suicides, discussing the challenges and the interpretative issues which a forensic pathologist might deal with. A thorough on-site judicial inspection and a careful autopsy examination are crucial in such cases. Moreover, the clinical history of the victims and laboratory findings are supplemental elements to be necessarily considered to establish the actual manner of death and avoid any misinterpretations.

Pattern of Suicide Methods and Postmortem Toxicological Findings in Suicide-Related Deaths: A Retrospective 7-Year Forensic-Based Study in Iran.

ABSTRACT: Suicide is a public health threat that leads to morbidity and mortality worldwide. In this study, we evaluated postmortem toxicological finding among forensic autopsies on suicidal deaths from 2010 to 2016 at the Legal Medicine Center of Zanjan Province (northwest of Iran). All suicide fatal cases were investigated to define the cause and manner of death. Toxicological analyses were performed using thin-layer chromatography, high-performance liquid chromatography, gas chromatography/mass spectrometry, headspace gas chromatography, and gas chromatography equipped with nitrogen phosphorus detector. Demographic data (age, sex, educational level, residential location, and marital status), cause of death, and postmortem toxicological findings were extracted from forensic reports and were entered into the designed questioners. During this period, a total of 181 cases of suicide deaths were investigated. Among them, 74% were male. The most often used suicide method was hanging, followed by self-poisoning in young people. Aluminum phosphide was the most frequent poison detected in the fatal suicidal cases (33 cases), followed by opioids. Hanging and self-poisoning were the frequent suicidal method in young male population. It seems that psychological and social supports in young people along with restriction to easy access to drugs and poisons should be considered by policy making and healthcare authorities.

Suicide by helium inhalation in the Netherlands between 2012 and 2019.

INTRODUCTION: In 2012 and 2013 a movie and a book about a 'dignified end of life' were published in the Netherlands. These items described suicide using an 'exit bag' to establish asphyxiation using helium (the helium method). 'Right-to-die-organisations' inform the elderly about this method. The purpose of this study is to investigate whether the use of suicidal asphyxiation by means of the helium method substituted other, related, methods following its publication in the Netherlands. MATERIAL AND METHODS: We analysed suicides in the Netherlands over the period from 1 July 2012 to 30 June 2019. We compared the number of deaths caused by the helium method with other, related, cases. Secondly, we related these deaths to the total number of inhabitants and suicides recorded by Statistics Netherlands. RESULTS: The study showed a stable trend in the use of the helium method in the period 2012-2019 and this was the same for the other, related methods. Individuals using the helium method were significantly younger than those using other, related, methods. At the scene of death, information about suicide and suicide notes were found more often at 'helium method' cases than with the 'other, related, methods' cases. Family was significantly more often present during a helium method suicide than during suicide by other, related, methods. DISCUSSION: The number of suicides by the helium method and other, related, cases is stable in the Netherlands over the past years. Therefore, we conclude that there is no substitution effect within this category of suicides. Whilst 'right-to-die-organisations' strive to inform the old and sick of the helium method, it is noteworthy that the individuals using the helium method are significantly younger than the individuals who choose other, related, methods.

Urban-rural Differences in Suicide Rates, by Sex and Three Leading Methods: United States, 2000-2018.

Suicide has remained the 10th leading cause of death in the United States since 2008, with deaths due to firearms, suffocation (including hangings), and poisoning representing the leading methods of suicide (1,2). There are known differences in suicide rates by sex and geographic distribution (3). This report uses final mortality data from the National Vital Statistics System to present trends in suicide mortality from 2000 through 2018 among all ages by urban-rural classification of the decedent's county of residence and sex for the leading methods of suicide-firearms, suffocation, and poisoning.

[Death due to physical restraint in healthcare institutions]. / Overlijden door fysieke fixatie in zorginstellingen.

Physical restraint is frequently used in healthcare institutions, usually in situations where the safety of the person (e.g. fall risk) or that of others (e.g. aggressive behaviour) is compromised, or where essential medical treatment is at stake. The implementation has a major impact with possible psychological consequences, physical injury and even fatal outcomes. In this retrospective study, fifteen deaths due to physical restraint are described. These have been investigated by the Forensic Medicine departments of UZ Leuven (1998 - 2018) and UZ Antwerpen (1999 - 2018). Death was caused by mechanical suffocation in all instances, mainly as a result of inadequate use of bedrails or belt restraint. These avoidable deaths are an urgent plea for a cautious and careful policy on physical restraint. Institutional guidelines and (further) training of health care personnel are of utmost importance. Central aspects are multidisciplinarity (deliberate decision-making), treatment (provoking factors), reticence (search for alternatives), proportionality (least intrusive method), due care (technical implementation), safety (increased supervision), temporality (re-evaluation of moment and duration), registration (accountability and liability) and communication (with all involved).

Risk factors for female and male homicidal strangulation in Johannesburg, South Africa.

BACKGROUND: There is a paucity of research on homicidal strangulation by gender. OBJECTIVES: A sex-disaggregated and comparative research approach was used to investigate individual-level risk factors for female and male homicidal strangulation in Johannesburg, South Africa (2001 - 2010). METHODS: Data were drawn from the National Injury Mortality Surveillance System. Logistic regressions were used to examine associations between each of the independent variables and homicidal strangulation in females and males relative to all other female and male homicides, respectively. RESULTS: The risk of fatal strangulation was high for both females and males aged ≥60 years, but markedly high only for male children and adolescents. Temporal risk for females was undifferentiated for day of the week, and the risk for males was high during weekdays. Females were more likely to be strangled in public places, and males in private locations. CONCLUSIONS: The study underlines the importance of disaggregating homicide by external cause and gender.

The role of restraint in fatal excited delirium: a research synthesis and pooled analysis.

The purpose of the present study was to perform a comprehensive scientific literature review and pooled data risk factor analysis of excited delirium syndrome (ExDS) and agitated delirium (AgDS). All cases of ExDS or AgDS described individually in the literature published before April 23, 2020 were used to create a database of cases, including demographics, use of force, drug intoxication, mental illness, and survival outcome. Odds ratios were used to quantify the association between death and diagnosis (ExDS vs. AgDS) across the covariates. There were 61 articles describing 168 cases of ExDS or AgDS, of which 104 (62%) were fatal. ExDS was diagnosed in 120 (71%) cases, and AgDS in 48 (29%). Fatalities were more likely to be diagnosed as ExDS (OR: 9.9, p < 0.0001). Aggressive restraint (i.e. manhandling, handcuffs, and hobble ties) was more common in ExDS (ORs: 4.7, 14, 29.2, respectively, p < 0.0001) and fatal cases (ORs: 7.4, 10.7, 50, respectively, p < 0.0001). Sedation was more common in AgDS and survived cases (OR:11, 25, respectively, p < 0.0001). The results of the study indicate that a diagnosis of ExDS is far more likely to be associated with both aggressive restraint and death, in comparison with AgDS. There is no evidence to support ExDS as a cause of death in the absence of restraint. These findings are at odds with previously published theories indicating that ExDS-related death is due to an occult pathophysiologic process. When death has occurred in an aggressively restrained individual who fits the profile of either ExDS or AgDS, restraint-related asphyxia must be considered a likely cause of the death.

Asphyxia Homicides in Finland, 1983-2012.

Finland has one of the highest homicide rates in Western Europe, and almost every tenth homicide is caused by asphyxiation. Reliable statistics, a strict legislation, and an exceptionally high medico-legal autopsy rate formed a base for a nationwide analysis of asphyxia homicides (n = 383) during 30 years. The cases were identified through multiple records, and all the forensic pathology case files were studied in detail. In more than one out of five cases, there were indications of staging, and the homicide was revealed first at autopsy in close to one in ten cases. The vast majority of the homicides took place in private locations and involved persons known to each other. Every third victim was an intimate partner, and every tenth a child. Almost half of the victims died from manual strangulation, one in three from ligature strangulation. Smothering, choking, neck compression with a firm object, and thoracic compression were more rare methods. Drownings were excluded from this study material. Of all the victims, 7% had no observable external injuries. Petechiae were recorded in approximately in 61%, laryngohyoid fractures in 47%, and vocal cord hemorrhages in 16% of the cases. Every tenth female victim had genital injuries. Toxicological analyses were performed in close to all of the cases, and almost three out of four victims tested positive for blood alcohol. The various aspects of the demographics and autopsy findings covered in this study contribute reliable and accurate data to further strengthen the spectrum of observable medico-legal characteristics of asphyxia homicides.

Recurrent sudden unexpected death in infancy: a case series of sibling deaths.

OBJECTIVES: To determine the rate of sudden unexpected death in infancy (SUDI) for infants born after a previous SUDI in the same family, and to establish the causes of death and the frequency of child protection concerns in families with recurrent SUDI. DESIGN: Observational study using clinical case records. SETTING: The UK's Care of Next Infant (CONI) programme, which provides additional care to families who have experienced SUDI with their subsequent children. PATIENTS: Infants registered on CONI between January 2000 and December 2015. MAIN OUTCOME MEASURES: Cause of death, presence of modifiable risk factors for SUDI and child protection concerns. RESULTS: There were 6608 live-born infants registered in CONI with 29 deaths. 26 families had 2 deaths, and 3 families had 3 deaths. The SUDI rate for infants born after one SUDI is 3.93 (95% CI 2.7 to 5.8) per 1000 live births. Cause of death was unexplained for 19 first and 15 CONI deaths. Accidental asphyxia accounted for 2 first and 6 CONI deaths; medical causes for 3 first and 4 CONI deaths; and homicide for 2 first and 4 CONI deaths. 10 families had child protection concerns. CONCLUSIONS: The SUDI rate for siblings is 10 times higher than the current UK SUDI rate. Homicide presenting as recurrent SUDI is very rare. Many parents continued to smoke and exposed infants to hazardous co-sleeping situations, with these directly leading to or contributing to the death of six siblings. SUDI parents need support to improve parenting skills and reduce risk to subsequent infants.

Autoerotic Deaths in Hamburg, Germany: Autoerotic accident or death from internal cause in an autoerotic setting? A retrospective study from 2004-2018.

INTRODUCTION: Autoerotic deaths are rare events. The death scene is often bizarre and the death unexpected, thus often requiring forensic autopsies. Our analysis will provide an overview of the expected range of causes and manners of death in cases of autoerotic deaths. METHODS: A retrospective analysis was carried out on all scientific and forensic autopsies and postmortem examinations performed at the Department of Legal Medicine in Hamburg, Germany, over the period of 2004-2018. RESULTS: 25 cases of autoerotic fatalities were identified over this 15-year-period or one to two cases per year, respectively. Autopsies were carried out on 23 of these cases. 16 (64%) of the cases involved autoerotic accidents and 7 (28%) from internal causes of death during an autoerotic act. Two cases had not undergone an autopsy. On average, those who were involved in autoerotic accidents had been younger in age (average age: 37 years) than the individuals who died from internal disease (average age: 61 years). Only one woman was involved. The most common cause of death in autoerotic accidents was strangulation (hanging: 8 cases, ligature strangulation: 1 case), followed by smothering of the respiratory tract (4 cases). Fatal intoxication was diagnosed in three of the cases. Fatalities with natural cause of death solely involved cardiovascular causes of death. CONCLUSIONS: Autoerotic deaths involved a wide range of natural and non-natural causes of death. The reconstruction of such unusual cases and detection of non-natural fatalities requires thorough investigation of the scene of death as well as a postmortem external and internal examination including a chemical toxicological and blood alcohol analysis.

Doble mecanismo de estrangulación. A propósito de un caso / Double mechanism of strangulation. Apropos of a case

RESUMEN Las asfixias mecánicas son aquellas que resultan del impedimento mecánico a la penetración del aire en las vías respiratorias, suelen clasificarse atendiendo a la naturaleza del medio mecánico que las origina y a su modo de actuar. La estrangulación puede definirse como la constricción del cuello mediante la aplicación de una fuerza activa, ajena al peso del cuerpo, que actúa por intermedio de un lazo, las manos, el antebrazo o cualquier otra estructura rígida. En la estrangulación antebraquial, la constricción del cuello se lleva a cabo normalmente rodeando al individuo con el brazo y el antebrazo. Cuando el mecanismo de la compresión del cuello es lateral, no se afectan las vías aéreas, la compresión de las arterias carótidas hace que se produzca una isquemia cerebral y pérdida de conocimiento en 10-15 segundos. El mecanismo de muerte en estos casos será la anoxia cefálica. Si la compresión del cuello es anterior, actúa ocluyendo las vías aéreas, la presión sobre los cartílagos tiroides y cricoides puede producir fracturas y el mecanismo de muerte será la obstrucción respiratoria. El presente trabajo constituyó un caso poco común de estrangulación, donde se utilizó un mecanismo combinado que llevó al occiso al deceso final. Para la realización de la discusión del caso se tuvo en cuenta los elementos del lugar del hecho, el examen del exterior y el interior del cadáver (AU).

ABSTRACT Mechanical asphyxias are those resulting from the mechanical obstruction of the air penetration in the airways. They are usually classified according to the nature of the mechanical mean producing it and the way it performs. Strangulation may be defined as neck constriction through the application of an active force not proper to the body weight, acting by means of a knot, hands, forearm or any stiff structure. In ante brachial strangulation, neck constriction is normally performed surrounding the individual with the arm and forearm. When the neck constriction mechanism is lateral, the airways are not affected: carotid arteries constriction produces a brain stroke and loss of consciousness in 10-15 s. The death mechanism in these cases will be cephalic anoxia. If the neck compression is anterior, it occludes the airways; the pressure on thyroidal and cricoid cartilages may produce fractures and death mechanism will be respiratory obstruction. The current work deals with an uncommon strangulation case, where a combined mechanism led the person to the final decease. For the case discussion the authors took into account the elements of the place, and the examination of the exterior and the inside of the corpse (AU).

Accidental deaths in young people with epilepsy and psychiatric comorbidity-A Danish nationwide cohort study.

OBJECTIVE: The objective of this study was to investigate the accident-related mortality among people younger than 55 years of age with epilepsy compared with the general population and to study how psychiatric comorbidity influences this risk. METHODS: This is a population-based cohort study of individuals born in Denmark between 1960 and 2015 (n = 3, 665 616). Persons diagnosed with epilepsy and psychiatric disorders were identified in the Danish National Patient Register and the Danish Central Psychiatric Central Register. We estimated the hazard ratio (HR) with 95% confidence intervals (CIs) of accidental death in people with epilepsy compared with persons without epilepsy. RESULTS: We identified 61 330 persons (1.7%) diagnosed with epilepsy. Median age at end of follow-up was 27.8 years. In people with epilepsy, 5253 died during follow-up, 480 (9%) of whom died from accidents. Among people without epilepsy, 52 588 died during follow-up, of whom 1280 (2.4%) died from accidents. People with epilepsy had a 3.7-fold (95% CI 3.4-4.1) increased risk of accidental death compared with persons without epilepsy. When we adjusted for psychiatric disorders, the risk remained significantly elevated in people with epilepsy compared to people without epilepsy (adjusted HR [aHR] 2.44, 95% CI 2.22-2.69). When stratifying the analyses on epilepsy and psychiatric disorders, people with epilepsy and psychiatric disorders had an aHR of 4.95 (95% CI 3.82-6.41) when compared with persons without epilepsy and psychiatric disorders. SIGNIFICANCE: The risk of accidental death was increased in people with epilepsy and was particularly high among people with epilepsy with psychiatric comorbidity. The findings highlight the need for awareness and prevention strategies in people with epilepsy, especially in people with comorbid psychiatric disorders.

Review of the pattern of traumatic limb lesions sustained in cases of hanging.

This retrospective study sought to identify a regular pattern of limb bruising which occurs in association with suicidal or accidental hanging. Following exclusion of cases suspicious for homicide, 82 consecutive cases of hanging from a 10-year period were retrospectively reviewed to identify the pattern of traumatic limb injury in each case. Relevant information such as location, toxicology, and type of suspension was also noted. 72% of the reviewed cases had traumatic limb lesions, the majority of which occurred on the posterior upper limb and the anterior lower limb. Although the distribution of limb injury in our study mirrored that found in the literature, the incidence is much higher than in previous studies (7.4-20%). This could either be due to differences in confounding factors such as intoxication and location of hanging or differences in the practice of recording of limb trauma in hanging between centres. Neither type of suspension nor location of hanging were significantly associated with an increased incidence of traumatic limb injury. Positive toxicology was found to increase the likelihood of sustaining limb injury (p = .044084). In conclusion, the presence of this well documented pattern of traumatic limb lesions in cases of hanging should not always raise suspicion of foul play.

Trends and patterns in homicides in Italy: A 34-year descriptive study.

AIMS: We aimed at analyzing homicide trends and patterns in Italy over the period 1980-2014. METHODS: We collected data from the Italian Mortality Database (Italian National Institute of Statistics), for the study period. Temporal trends were analyzed using joinpoint regression analysis, with estimated annual percentage change computed for each detected trend. The possible effect of the mafia subculture was examined using an indicator of mafia social penetration. Differences between age classes, genders, geographical regions, and homicide methods were also analyzed. RESULTS: The analyses showed an overall reduction in homicides during the study period, including a reduction in homicides by firearm. Further, we found significant differences between homicides involving male and female victims. A peak in male homicides, observed in the early 1990s, was significantly associated with mafia penetration. CONCLUSIONS: The overall reduction in homicides can be interpreted as an expression of a "civilizing process."
