INTRODUCTION & OBJECTIVES: Road traffic accidents (RTAs) is a leading cause of morbidity and mortality in low and middle income countries. Human, vehicle and environmental factors are identified as causative agents. The objective was to identify location and causes of RTA related to motorcycle and three-wheeler drivers brought to Colombo North Teaching Hospital (CNN). METHODS: A descriptive cross sectional study was conducted from 15/12/2018 to 10/12/2019 at the CNTH. 104 motorcycle riders and 49 three-wheeler drivers following an accident were included. Data related to human, vehicle, road factors and demographic details were collected using an interviewer administered questionnaire. The location of accident was mapped using Google earth with colour coding for category of hurt, to identify geographical distribution. RESULTS: Motorcycle Accidents: 17.3% were under the influence of alcohol at the time of accident. Mean speed of vehicle at the time of accident was 42.2 kmph. 42.3% of riders who did not wear the helmet properly sustained grievous injuries. 42.5% of employed riders experienced an income loss. Three-wheeler Accidents: 22.4% were under the influence of alcohol at time of accident. Mean speed of vehicle at the time of accident was 46.94 kmph. 49% of accidents took place at a turn. 63.6% of employed drivers experienced an income loss. Mean income loss for motorcycle and three-wheeler drivers were Rs. 2326 and Rs.2816, respectively. CONCLUSION: Human and environmental factors have been responsible for majority of accidents. There are areas in Ragama where drivers should be cautious.

(Faculty of Medicine, University of Kelaniya, Sri Lanka, 2021) Alwis, D.N.; Govinnage, D.P.S.; Kulathunga, D.L.; Perera, W.N.S.; Paranitharan, P.
Introduction: Using firearms is one of the methods of committing a homicide. In Sri Lanka use of firearms was prominent among terrorists and underworld criminals. The analysis of the injury pattern will help to find the trends related to firearm injuries. Deaths that deviate from the routine pattern of injuries will be highlighted. Objectives: The objective of the study was to identify injury patterns in firearm related deaths. Methods: The data from 40 firearm related autopsy reports belonging to the investigators from the years 2000 to 2019 were entered to SPSS statistical package for analysis, based on a pre-prepared questionnaire. Results: Majority were in between 21 and 40 years (75%) and male (97.5%). Head alone was involved in 25% of deaths and head in combination with other regions was involved in 40% of the deaths. Cause of death (COD) in 50% of cases was head injuries alone and in 12.5% cases COD was from head injuries in combination of other injuries. Main motive was homicide in 72.5% of cases. Rifled firearm was the commonest weapon (90%). Range was distant in 65% of cases followed by close range in 17.5% of cases. Range was decided by the history, if available, appearance of entry wound and other observations. Conclusions: Scientific evaluation of deaths following firearm injuries demands proper assessment of range based on modem technology. This becomes more relevant if there is an incompatibility with the history and the appearance of the wound, especially when deciding circumstance of death.
A retrospective descriptive study on deaths due to firearm injuries in Western Province, Sri Lanka
(Department of Forensic Medicine, Faculty of Medicine at University of Peradeniya, 2023) Alwis, D.N.; Govinnage, D.P.S.; Kulathunga, D.L.; Perera, W.N.S.; Paranitharan, P.
INTRODUCTION: The use of firearms is a well-recognized method of committing a homicide. In Sri Lanka, the use of firearms was prominent among terrorists and underworld criminals. The analysis of the injury pattern will help to find the trends related to firearm injuries. Deaths that deviate from the routine pattern of injuries will be highlighted. OBJECTIVES: The objective of the study was to identify injury patterns in firearm-related deaths and the methods used to identify the range. METHODS: The data from 40 firearm-related autopsies conducted at Offices of the Judicial Medical Officer at Colombo North Teaching Hospital, Colombo South Teaching Hospital, and Office of the Judicial Medical Officer, Colombo from 2000 to 2019 were collected from the post-mortem reports using pre-formed questionnaires and entered into the SPSS statistical package for analysis. RESULTS: The majority were between 21 and 40 years of age (75%) and male (97.5%). Head alone was involved in 25% of deaths and head in combination with other regions was involved in 45% of the deaths. Cause of death (COD) in 50% of cases was head injuries alone and in 12.5% of cases, COD was from head injuries in combination with other injuries. The commonest circumstance was homicide in 72.5% of cases. Rifled firearm was the most common weapon used (90%). Range or the distance of fire was in the distant range in 65% of cases followed by close range in 17.5% of cases. Distance of fire was decided by the history, if available, the appearance of the entry wound, and other observations. CONCLUSIONS: Scientific evaluation of deaths following firearm injuries demands proper assessment of the range or the distance of fire based on modern technology. This becomes more relevant if there is an incompatibility with the history and the appearance of the wound, especially when deciding the circumstance of death.
A Study on victims of intimate partner violence reported to Colombo North Teaching Hospital, Sri Lanka during 2019-2021
(Academic Forensic Pathology International, La Jolla, CA, 2022) Muthulingam, T.; Edirisinghe, P.A.S.; Wijewardhane, H.P.; Thivaharan, Y.; Jayasundara, M.M.S.; Borukgama, N.; Kulathunga, D.L.; Alwis, D.N.; Govinnage, P.S.; Kitulwatte, I.D.G.
Introduction: Intimate partner violence (IPV) is a common issue in any society and the reported cases are just the tip of an iceberg as most of the victims are reluctant to come to the criminal justice system. Forensic experts are often encountering the victims who chose to seek justice. Evaluation of the nature, consequences, and underlying factors are needed in planning preventive measures. Objectives: To describe the patterns and associated factors of IPV among victims who reported to Office of the Judicial Medical Officer of Colombo North Teaching Hospital and to specifically describe the patterns prior and during the COVID-19 pandemic. Methods: A retrospective descriptive study based on 471 medicolegal records of the victims who had undergone medicolegal examination following IPV during last two years (March 2019 to February 2021). Results: Out of 471, 206 cases were reported prepandemic and 265 reported postpandemic periods. Even though majority were females there were 21 males. Types of abuse were complex and often interrelated. There were 463 who had experienced physical injuries while there were 20 who had been subjected to sexual violence. Face was the commonest target of assault (63%). Substance abuse was identified as the commonest predisposing factor (56%). Even though repeated abuse was common, 42.5% of the victims had never made any complaints to the police. Despite multiple complains, 39.7% had experienced repeated violence. Conclusion: Victims of IPV are silently suffering for many long years. Failure in the response from authorities was identified. COVID-19 pandemic has become an additional risk factor for IPV. Strengthening of legal and social responses is the need of the hour.
