Background: Motorcycle fatalities constitute the majority of road traffic deaths in Malaysia. The aims of this study were to describe the pattern of fatal injuries among Klang Valley fatal motorcyclists and to describe the factors associated with fatal (vs non-fatal) injuries. Methods: A cross-sectional analysis was performed on data from a case series of injured (fatal and nonfatal) motorcyclists recruited from Klang Valley between 14th March 2010 and 13th March 2011. Fatal cases in the cases series were identified from the Police files. Non-fatal cases were recruited from five major hospitals in the study region. Information used in the analyses were obtained from Police crash reports, hospital medical records, and Coroner's records of the participant sample. Results: Of the 177 fatal cases, 142 (80.2%) were categorised as instantaneous death while 35 (19.8%) cases were categorised as experiencing delayed death. Thirty two percent of the cases had a Maximum Abbreviated Injury Score (MAIS) of 5 with head injury being the most common cause of death. Significant predictors of fatal (vs non-fatal) injury included ethnic groups, monthly income, alcohol and drug use and road type. Alcohol and drug use was shown to be the strongest predictor with adjusted odds ratio (AOR) of 14.77 (95% CI 3.32e65.65). Conclusion: Factors related to the motorcyclists, road user behaviour and the road environment as well as pre-hospitalisation emergency care must be addressed efficiently in low and middle income countries to reduce the number and severity of motorcycle-related injuries.

Paraesthesia or anaesthesia is a well-documented complication following mandibular third molar surgery. This retrospective study was designed to investigate the occurrence of nerve morbidity following surgical removal of mandibular third molar and to determine the factors that may influence or contribute to it. Records of 178 patients who attended the Oral and Maxillofacial Surgery Clinic, Faculty of Dentistry, Universiti Kebangsaan Malaysia or Hospital Universiti Kebangsaan Malaysia for removal of their mandibular wisdom teeth from January 1998 to December 2002 were selected. Results showed that 3.4% inferior alveolar nerve morbidity was noted in the form of temporary paraesthesia. Inferior alveolar nerve morbidity was greater with mesioangular impaction and when the teeth were removed under local anaesthesia. The mean age of patients with nerve morbidity was 32.2 years old.
