METHODS: A cross sectional study on nationally representative sample deaths that occurred in Malaysia during 2013 was used. A VA questionnaire suitable for local use was developed. Trained field interviewers visited the family members of the deceased at their homes and conducted face to face interviews with the next of kin. Completed questionnaires were reviewed by trained physicians who assigned multiple and underlying causes. Reference diagnoses for validation were obtained from review of medical records (MR) available for a sample of the overall study deaths.
RESULTS: Corresponding MR diagnosis with matched sample of the VA diagnosis were available in 2172 cases for the validation study. Sensitivity scores were good (>75%) for transport accidents and certain cancers. Moderate sensitivity (50% - 75%) was obtained for ischaemic heart disease (64%) and cerebrovascular disease (72%). The validation sample for deaths due to major causes such as ischaemic heart disease, pneumonia, breast cancer and transport accidents show low cause-specific mortality fraction (CSMF) changes. The scores obtained for the top 10 leading site-specific cancers ranged from average to good.
CONCLUSION: We can conclude that VA is suitable for implementation for deaths outside the health facilities in Malaysia. This would reduce ill-defined mortality causes in vital registration data, and yield more accurate national mortality statistics.
MATERIALS & METHODS: This was a cross-sectional study involving 101 subjects recruited from the National Institute of Forensic Medicine (IPFN) Hospital Kuala Lumpur (HKL) over a period of 15 months, from December 2012 until April 2014. PMCT CS of the coronary arteries was calculated using Agatston-Janowitz score. Histological presence of calcification was observed and the degree of stenosis was calculated using an image analysis technique.
RESULTS: PMCT CS increased with increasing severity of stenosis (p<0.001). PMCT CS showed a positive correlation with the presence of calcification (r=-0.82, p<0.001).
CONCLUSION: Calcium score is strongly associated with coronary artery calcification and the degree of luminal stenosis in post mortem subjects. Thus, PMCT may be useful as a non-invasive tool in diagnosing CAD in the event that an autopsy is not possible.
METHODS: This is a retrospective study of post mortem cases at Hospital Kuala Lumpur from 2014 to 2016. Deaths from RTC were included while decomposed and homicide cases were excluded. We performed Spearman Correlation statistical test to relate RTC and positive DoA results.
RESULTS: A total of 523 RTC cases were identified in which either blood or urine or both samples were taken for toxicology. 93 cases were positive for both DoA and therapeutic drugs. A total of 37 cases were positive for DoA. Alcohol was present in 5 out of 37 DoA positive cases. Most of the cases seen among 16 to 45 years old (69%) and predominantly in males (93.1%). 29 out of 37 were motorcyclist and the rest were pillion rider and pedestrian. Spearman Correlation statistical test showed a negative relationship between RTC and positive DoA results.
DISCUSSION AND CONCLUSION: Majority of the DoA cases in RTC were identified in the younger age group and among the motorcyclist. Spearman Correlation statistical test showed that more cases of DoA died in natural or suicidal manner compared to RTC. However, this doesn't reflect the true association of DoA in RTC. This is because of mainly two factors which the delayed effect of DoA that gives negative toxicology test and also the influence of other road users on DoA.
Methods and Results: The study population was the postmortem cases of Asian population ranging from 16 to 75 years old in which blood and/or urine samples sent for alcohol and/or drug of abuse (DoA) analysis in year 2016 at our centre. Out of 434 cases, 54 from each group of positive and negative alcohol and/or DoA. Postmortem findings of lungs and postmortem CT scan urinary bladder volume (UBV) were recorded. Statistical significant correlation was obtained between urinary bladder distension on postmortem CT scan and cases with positive alcohol detection. However, the sensitivity was relatively low at 51.7%, whereas the specificity was 75% at the cut-off point. Low sensitivity and specificity at around 52.7% were obtained for pulmonary edema related to alcohol/DoA. This showed that UBV alone or pulmonary edema alone was not really a good indicator for alcohol or DoA intoxication. However, combination of both indicators provided higher sensitivity (73.3%) although specificity was lowered to 53.8%.
Conclusion: The findings of postmortem CT scan bladder distension and pulmonary edema could possibly identify intoxication cases but not conclusive.
