Study on unnatural childhood deaths presented to North Colombo Teaching Hospital, Sri Lanka

Patterns of Unnatural Deaths Among Children and Adolescents: Autopsy Study (2011-2018)

BACKGROUND AND AIMS

The problem of unnatural death in children is still relevant because of their vulnerability. This work aimed to describe the epidemiological profile and patterns of these medicolegal deaths in children and adolescents in northern Tunisia.

METHODS

We conducted a retrospective study from January 2011 to December 2018, within the Forensic Department of Charles Nicolle Hospital in Tunis. All children who died of unnatural causes were included (767 cases).

RESULTS

An overall male predominance was observed (sex ratio = 2.4). Accidental deaths represent the most common manner of death (81.4%) involving most frequently domestic accidents occurring in children aged between 1 and 4 years. In cases of suicide, the highest risk profile was a female child aged between 15 and 18 years. The suicide occurred most often in the victim's home with hanging representing the common means of suicide. For the criminal form, the most common means in those cases were stabbing and blunt injuries.

CONCLUSION

Our study delivered a broad picture of unnatural deaths among children in Tunisia. These deaths, largely absent from child survival initiatives presently on the global agenda, can be prevented if they are addressed strategically, as their injury prevention strategies differ from adults.

Fatal intentional drowning in Australia: A systematic literature review of rates and risk factors

INTRODUCTION

Unintentional drowning deaths are only part of the drowning profile, with little attention being paid to intentional drowning in Australia. Strategies for the prevention of intentional drowning deaths are likely to be different from unintentional. Quality documentation, analysis and dissemination of intentional deaths data is crucial for developing appropriate strategies for prevention.

OBJECTIVE

To conduct a systematic literature review to investigate the mortality rates and risk factors of intentional drowning deaths in Australia.

METHODS

A systematic search guided by PRISMA was performed using Ovid MEDLINE, CINAHL, PsycINFO (ProQuest), Scopus, Google Scholar, and BioMed Central databases to locate relevant original research articles published between 2007 and 2018.

RESULTS

Ten papers reporting the mortality rates and risk factors of intentional drowning deaths in Australia published between 2007 and 2018, with study periods of the included articles spanning from 1907 to 2012, were reviewed. Most studies investigated suicidal drowning deaths in Australia, none reported homicidal drowning deaths. The downward trend of fatal suicide drowning was identified in Australia. The annual rate of intentional drowning between 1994 and 2012 can be inferred from eight studies, ranging from 0.06 to 0.21 for nation-wide mortality rates. The highest annual state-wide mortality rate was identified in the state of Queensland, ranging from 0.02 to 0.11 per 100,000 individuals. Of four studies examining the risk factors of fatal intentional drowning in Australia, being of older age groups, being female, and the presence of substance use were identified as important factors for suicidal drowning deaths. The national-scale proportion of suicide drowning in Australia, ranging from 2% to 3% of all intentional self-harm deaths, was also identified.

CONCLUSION

Limited publications reporting the mortality rates and risk factors of intentional drowning deaths in Australia were identified. Being of older age groups and being female were recognised as factors for suicide drowning deaths, and psychoactive substances were widely identified amongst cases. Future research on improving death reporting systems and the legal framework for medico-legal death investigation, along with the investigation of the risk factors of intentional drowning, are required to inform the planning, implementation, and evaluation of prevention interventions for intentional drowning deaths in Australia.

Cases of asphyxia in children and adolescents: a retrospective analysis of fatal accidents, suicides, and homicides from 1998 to 2017 in Hamburg, Germany

PURPOSE

Injury-related asphyxia is one of the most common causes of death in children in Germany. However, only a few systematic studies have analyzed the causes and circumstances of asphyxia in children and adolescents.

METHODS

All cases of asphyxia in children and adolescents (0-21 years of age) among the Hamburg Legal Medical Department's autopsy cases from 1998 to 2017 were retrospectively analyzed with special focus on how often external findings were completely absent.

RESULTS

Among 249 cases of fatal asphyxia, 68% were accidents, 14% were suicides, and 13% were homicides. Most of the cases involved boys. Adolescents and young adults aged 15-21 years represented the main age group. Drowning was the leading mechanism of asphyxia. Younger age was associated with less frequent detection of external signs of asphyxia in the postmortem external examination. Petechial hemorrhages were the most common visible external indication of asphyxia. No external findings indicative of asphyxia were present in 14% of the cases.

CONCLUSION

Asphyxia in children and adolescents often involves accidents. However, postmortem external examination alone is insufficient to identify asphyxia and the manner of death.

The epidemiology of drowning in low- and middle-income countries: a systematic review

Background

According to the World Health Organization, drowning is the 3rd leading cause of unintentional injury-related deaths worldwide, accounting for 370,000 annual deaths and 7% of all injury-related deaths. Low- and middle-income countries are the most affected, accounting for 91% of unintentional drowning deaths.

Methods

The authors performed a systematic review of literature indexed in EMBASE, PubMed, Web of Science, Cochrane Library, and Traumatology journals formerly indexed in PubMed in January 2014 and again in September 2016. Abstracts were limited to human studies in English, conducted in low- and middle-income countries, and containing quantitative data on drowning epidemiology.

Results

A total of 62 articles met inclusion criteria. The majority of articles originate from Asia (56%) and Africa (26%). Risk factors for drowning included young age (<17–20 years old), male gender (75% vs. 25% female), rural environment (84% vs. 16% urban), occurring in the daytime (95% vs. 5% night time), lack of adult supervision (76% vs. 18% supervised), and limited swimming ability (86% vs. 10% with swimming ability). There was almost equal risk of drowning in a small body of water versus a large body of water (42% ponds, ditches, streams, wells; 46% lakes, rivers, sea, ocean).

Conclusion

Drowning is a significant cause of injury-related deaths, especially in LMICs. Young males who are unsupervised in rural areas and have limited formal swimming instruction are at greatest risk of drowning in small bodies of water around their homes. Preventative strategies include covering wells and cisterns, fencing off ditches and small ponds, establishing community daycares, providing formal swimming lessons, and increasing awareness of the risks of drowning.
