Abstract
INTRODUCTION Childhood injury is one of the leading causes of death globally, with falls being the sixth leading cause. This study aimed to examine the demographics, patterns of injury and temporal risk factors for falls from height above 3 m in Singapore. METHODS This is a retrospective study conducted on patients who presented after a fall to a paediatric emergency department at a tertiary hospital between January 2011 and July 2017. Electronic medical records were reviewed to extract demographics and data on the patterns of injuries. Criteria for inclusion were patients under 18 years of age and the occurrence of fall from a height of 3 m or above. RESULTS A total of 149 children met the inclusion criteria. The median age was 10 years and 69.1% were boys. Death occurred in two (1.3%) cases; 84 (56.4%) were admitted and survived. Of those admitted, five (3.4%) required care in the intensive care unit and 11 (7.4%) required surgery. Falls occurred mostly at homes or residential buildings (n = 59, 39.6%). The two cases of mortality were due to falls from windows at homes. Twenty (33.9%) children fell from windows at homes, with two requiring admission to the intensive care unit. CONCLUSION Our study shows that falls from windows of homes are an important cause of mortality. Height of fall was also an important predictor of morbidity that led to a higher level of hospitalisation care. Preventive measures should be implemented to ensure safety in high-rise residential buildings to prevent paediatric falls from heights.

Abstract
PURPOSE The aim of the study is to enhance understanding, raise awareness and inform prevention programmes regarding potential factors that lead to severe paediatric injuries caused by unintentional falls from windows. METHODS This is a retrospective review from a major Trauma Centre, covering the majority of North West England and North Wales and included children under the age of 16 that had sustained falls from windows and were hospitalised between April 2015 and June 2020. RESULTS Overall, 825 patients' records have been reviewed, 39% of which exhibited neurosurgical injuries (322 admissions). The most common cause of injury was falls (42%), out of which 19% was identified as falls from windows which was eventually the core focus of this review (25 patients). The records showed that 72% of the falls were not witnessed by another individual, suggesting that children were being left unattended. Average GCS recorded at presentation was 11.2 and 56% of cases were identified as severe major traumas. With a mean stay of 2.2 days in ICU, 1.6 days in HDU and 6 days in the neurosurgical clinic, average treatment costs per patient were £4,493, £651 and £4,156 respectively. Finally, 52% of patients were identified to require long-term physiotherapy/occupational therapy due to permanent disabilities, 20% long-term antiepileptic treatment for seizures and 44% long-term psychological services input. CONCLUSION This study presents our experience at a major tertiary trauma centre in the UK over a 5-year period, from a paediatric neurosurgical injuries perspective due to fall from windows. We aim to raise awareness and highlight the importance of establishing prevention programmes which would hopefully decrease the incidence of paediatric window falls.

Unmasking the Underlying Causes: A Cross-Sectional Analysis of Mortality From Intentional and Unintentional Injuries in the United Arab Emirates. Cureus 2023; 15:e46567. [PMID: 37933336 PMCID: PMC10625665 DOI: 10.7759/cureus.46567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/05/2023] [Indexed: 11/08/2023] Open
Abstract
The United Arab Emirates (UAE) has experienced substantial development in infrastructure and transportation in the last few decades. Although available evidence suggests that the incidence of injuries has considerably increased in the previous few years, there is a scarcity of literature that comprehensively analyzed the mortality due to different types of injuries in the UAE. Therefore, the current study was designed to report mortality due to various intentional and unintentional injuries in the UAE. Secondary data was obtained from the World Health Organization (WHO) mortality database. We targeted injuries-specific mortality datasets. We applied a filter (UAE) to retrieve mortality data from unintentional and intentional injuries in the UAE. The latest data in the WHO mortality database was for 2020-21. A total of 10,357 death records from the UAE were present in the WHO mortality database. The percentage of injury-specific deaths out of total deaths was 8.69% (n=900). Injury-specific mortality rate per 100,000 population was 9.09. The percentage of injury-specific deaths was higher for males (87.3%, n=786) and the age group 25-34 years (n=323, 35.9%). Of the 900 injury-specific deaths, 449 (49.9%) were due to unintentional injuries, 216 (24.0%) were due to unintentional injuries, while the remaining (26.1%, n=235) deaths occurred due to Ill-defined injuries. More than half (53.7%, n=241) of unintentional injuries were because of road traffic injuries (RTIs) followed by fall (14.7%, n=66), exposure to mechanical forces (6.5%, n=29), drowning (6.0%, n=27) fire (1.1%, n=5), poisonings (1.1%, n=5), natural disasters (n=1, 0.2%) and other unintentional injuries (16.7%, n=75). More than three-quarters (83.3%, n=180) of intentional injuries were because of self-inflicted injuries while the remaining (16.7%, n=36) intentional injuries-specific deaths occurred due to violence. Many deaths in the UAE occur due to unintentional and intentional injuries. RTIs and falls are the leading causes of unintentional injury-specific deaths, while self-inflicted injuries and violence are the leading causes of intentional injury-specific deaths.

Abstract
BACKGROUND Accidental falls are a common cause of disability and trauma-related death in the pediatric population, accounting for a large number of pediatric emergency hospital admissions. This multicenter study assesses the clinical characteristics, management outcomes of pediatric falls-related traumatic brain injury and associated factors in Nigeria. METHODS A retrospective study of pediatric patients (age less than 18-years) with falls over a 2-year period. Data was extracted from clinical records and neurosurgical data sheets from three major centres in Nigeria, and was analyzed using descriptive statistics, Chi square test and multinomial regression with significance set at p < 0.05. RESULTS 128 children presented with fall-related TBI, with a median age of 96 months (age range of 5-216 months) and M:F was 6:1. 40.6 % had moderate head injury and 55.5 % of the falls were building related. There were 52(42.6 %) children with skull fractures. Older children more commonly fell from trees and had more cases of severe head injury (14.1 %) compared with those who fell from buildings (5.5 %). Children who fell from buildings presented early (64.1 %). The 10 % mortality was mainly in children older than 5-years. Children aged 0-5 years were three times likely to fall inside/outside a building (OR: 3.3, CI: 3.06 to 243.44). Also, those who fell from trees were 6 times more likely to have a long bone fracture (OR: 6.1, CI: 1.2 to 32.6). CONCLUSIONS In the Nigerian population Traumatic Brain Injury from falls is common among children, with older children falling more from trees and associated with high mortality.

Abstract
BACKGROUND Research on child maltreatment and protection in the Arab Gulf Cooperation Council countries-Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates (UAE)-is limited but growing, as is child protection as a sector. OBJECTIVES We aimed to identify themes and gaps in existing research on child maltreatment and protection, identify opportunities for building capacity in research and practice. PARTICIPANTS AND SETTING N/A. METHODS We conducted a scoping review of empirical studies published in peer-reviewed journals in English and Arabic and reported methods and findings according to the PRISMA-ScR reporting protocol. Articles were coded by country, topic of research, and type of abuse studied, if any. RESULTS Our database search returned 6109 articles and 160 articles were included in our review. Themes included (1) prevalence, incidence, and characteristics of maltreatment, (2) outcomes associated with maltreatment, (3) attitudes, awareness, and reporting, (4) accidental injury and death potentially associated with neglect, (5) policy and practice. Eighty-seven articles studied Saudi Arabia, while 28 studied the UAE, 21 Kuwait, 13 Qatar, 12 Oman, and 11 Bahrain. Physical abuse was studied in 77 articles, followed by sexual abuse in 54 articles and emotional abuse in 54. CONCLUSION Although the medical community produces an encouraging volume of child maltreatment research, gaps remain. Intervention research is lacking, and further inquiry into family dynamics, culture, and spirituality could inform the development of effective interventions. Cross-sectoral collaboration among education, social work, law enforcement, and healthcare is also needed to safeguard children's rights in the GCC.

Abstract
Traffic-related injuries are a serious health problem. Traffic safety is a priority reflected in the United Nations Sustainable Development Goals. Data on current hazards for bicycle-related injuries from the United Arab Emirates are lacking. The aim of our observational study was to assess the behavior of bicyclists on the roads in Al Ain City, United Arab Emirates and compare our current results with a previous study from 2004.We adapted and tested a structured data collection form. Different sectors of Al Ain were randomly selected to cover the whole city during different times. Bicyclists were observed without direct contact.Out of 1129 bicyclists, 97.6% were males and 13.2% children. 39.4% were cycling on main roads with high-density traffic, 33.1% were cycling against the traffic, 39.3% were cycling at night, and 96.8% of them were not using lights. Only 2.1% of the bicyclists used helmets. A higher proportion of female than male cyclists used helmets (25.9% vs 1.5%; P < .001, Fisher exact test). There was an increase in cycling with the traffic (P < .001) and in use of helmets (P < .025) compared with the previous study.Unsafe practices of bicyclists and low use of helmets despite legislation persist in Al Ain. There is a need to raise bicycle safety awareness and improve enforcement of bicycle helmet legislation. This should be directed toward expatriate workers, children, parents, and maids. Environmental changes, namely building separate bicycle lanes, can increase safety for cycling.

Abstract
AIM To describe patterns of injury from window and balcony falls in children presenting to a tertiary paediatric trauma centre in New South Wales. METHODS A retrospective review of cases of children <15 years who had sustained injuries in a fall from a building, identified from the trauma database between 1998 and 2019. RESULTS A total of 381 falls from windows and balconies were recorded over the 22-year study period. There were 218 falls from windows (57%) and 163 from balconies. The majority (64%) were children under 4 years of age. The male to female ratio was 2:1. While many children sustained simple abrasions, contusions and lacerations, 17% sustained injuries with an injury severity scores of ≥12. There were four deaths. CONCLUSIONS This study identified that children falling from buildings remains a problem in Australia. Although many injuries were minor, severe injuries and fatalities continue to occur.

Abstract
Background Unintentional falls from windows and balconies pose a serious health risk to children. Limited Canadian data describing such falls currently exist. This study aimed to describe the frequency, demographic characteristics, injury patterns, and risk factors associated with paediatric falls from windows and balconies. Methods This study employed both prospective data collection and retrospective medical record review. Prospectively, consenting families were enrolled from February 2015 to February 2017; retrospectively, charts from January 2009 to December 2014 were reviewed. Children 0 to 16 years of age, who presented to the Stollery Children's Hospital (Edmonton, Alberta) emergency department due to a fall from a window or balcony, were included. Results A total of 102 children were included; thirty were enrolled prospectively and 72 retrospectively. Median age was 4.5 years (interquartile range 2.83 to 6.83) with 63.7% (65 of 102) males. About 87.2% (89 of 102) of falls were from windows and 12.8% (13 of 102) from balconies. The median estimated height of fall was 4.1 m (interquartile range 3.04 to 4.73). About 58.4% (59 of 101) had at least one major injury (i.e., concussion, fractured skull, internal injury, fractured limb, severe laceration), 36.6% had minor injuries only (i.e., abrasions, contusions, sprains), and 5.0% had no documented injuries. There were no fatalities. About 30.4% (31 of 102) were admitted, with 48.4% of these children (15 of 31) requiring surgery. Conclusion Most falls from windows and balconies occurred in children under the age of 5 years and were associated with serious morbidity, high admission rates, and need for surgery. Child supervision as well as installation of key safety features in windows may help minimize paediatric fall-related injuries.

Abstract
Traumatic brain injury (TBI) is a major public health problem among children. The predominant causes of TBI in young children are motor vehicle accidents, firearm incidents, falls, and child abuse. The limitation of in vivo studies on the human brain has made the finite element modelling an important tool to study brain injury. Numerical models based on the finite element approach can provide valuable data on biomechanics of brain tissues and help explain many pathological conditions. This work reviews the existing numerical models of a child’s head. However, the existing literature is very limited in reporting proper geometric representation of a small child’s head. Therefore, an advanced 2-year-old child’s head model, named aHEAD 2yo (aHEAD: advanced Head models for safety Enhancement And medical Development), has been developed, which advances the state-of-the-art. The model is one of the first published in the literature, which entirely consists of hexahedral elements for three-dimensional (3D) structures of the head, such as the cerebellum, skull, and cerebrum with detailed geometry of gyri and sulci. It includes cerebrospinal fluid as Smoothed Particle Hydrodynamics (SPH) and a detailed model of pressurized bringing veins. Moreover, the presented review of the literature showed that material models for children are now one of the major limitations. There is also no unambiguous opinion as to the use of separate materials for gray and white matter. Thus, this work examines the impact of various material models for the brain on the biomechanical response of the brain tissues during the mechanical loading described by Hardy et al. The study compares the inhomogeneous models with the separation of gray and white matter against the homogeneous models, i.e., without the gray/white matter separation. The developed model along with its verification aims to establish a further benchmark in finite element head modelling for children and can potentially provide new insights into injury mechanisms.
