    Motorcycle casualties represent significant number in road traffic accidents in Malaysia, and among all the injuries, facial injuries pose many significant problems physiologically, functionally, and aesthetically. The aim of this study was to analyze the pattern of maxillofacial as well as other injuries in motorcyclists who were seen at Hospital Universiti Kebangsaan Malaysia.Patients' records from January 2004 to December 2005 were reviewed. Data related to demographics, vehicle/object involved in collision, involvement as a rider or pillion, whether a helmet was worn or not, location of injuries on the face/facial bones, and other associated injuries were collected.A total of 113 cases of motorcycle accidents were recorded; 106 males and 7 females were involved. Mean age was 25.8 years. Among all the races, Malay had the highest involvement (72.3%), followed by Chinese (14.3%), Indians (8.9%), and others (5.4%). The types of collision were either a single-vehicle collision (i.e., skidded) or with another vehicle/s or object (e.g., tree, stone, or lamppost). The injuries were mainly seen on the lower face (46.9%) followed by midface (25.7%) and a combination of the midface and lower face (15%) and others (12.4%). The most frequent other associated injuries recorded were orthopedic and head injuries.

    Pain assessment in older individuals with cognitive impairment is challenging. Evidence on the performance of pain assessment tools in this population remains limited. The aim of this study was to evaluate the performance of self-reported pain, nurse-reported pain, and observational pain tools among older patients with cognitive impairment using a prospective observational design. In all, 152 older individuals admitted to the acute geriatric ward were recruited through convenience sampling. Three methods of pain assessment were compared: self-reported pain (SRP), observational pain using the Pain Assessment in Advanced Dementia (PAINAD) tool, and nurse-reported pain (NRP). Cognition and mood were assessed with the Mini-Mental State Examination (MMSE) and the 15-item Geriatric Depression Scale (GDS-15). There was moderate agreement between SRP and PAINAD (k = 0.438) and fair agreement between SRP and NRP (k = 0.263). There was statistically significant correlation between SRP and GDS-15 (r = 0.382, p r = 0.018, p = .824). These results suggest that the use of an observational pain scale would be helpful in pain assessment among older individuals when the ability to report pain is not possible. However, self-reported assessments should be attempted first for cognitively impaired patients.

    BACKGROUND/AIM: The effects of pericardium 6 (P6) electrical stimulation in patients at risk of postoperative nausea and vomiting (PONV) following laparoscopic surgery were evaluated.

    MATERIALS AND METHODS: Eighty patients for laparoscopic surgery with at least one of the determined risks (nonsmoker, female, previous PONV/motion sickness, or postoperative opioid use) were randomized into either an active or sham group. At the end of surgery, Reletex electrical acustimulation was placed at the P6 acupoint. The active group had grade 3 strength and the sham group had inactivated electrodes covered by silicone. It was worn for 24 h following surgery. PONV scores were recorded.

    RESULTS: The active group had significantly shorter durations of surgery and lower PONV incidence over 24 h (35.1% versus 64.9%, P = 0.024) and this was attributed to the lower incidence of nausea (31.4% versus 68.6%, P = 0.006). The overall incidence of vomiting was not significantly different between the groups, but it was higher in the sham group of patients with PONV risk score 3 (23.9%, P = 0.049).

    CONCLUSION: In patients at high risk for PONV, P6 acupoint electrical stimulation lowers the PONV incidence by reducing the nausea component. However, this reduction in nausea is not related to increasing PONV risk scores.

    INTRODUCTION: The coronavirus disease 2019 (COVID-19) caused a global pandemic that resulted in devastating health, economic and social disruption. Pregnant mothers are susceptible to COVID-19 complications due to physiological and immunity changes in pregnancy. We aimed to assess the maternal vaccine acceptance of the COVID-19 vaccine.

    METHODS: A multi-center study across four teaching hospitals in the Klang Valley, Malaysia was conducted between September 2021 and May 2022. A survey was conducted using a self-administered electronic questionnaire. The survey instruments included; (1) maternal perception and attitude toward COVID-19 vaccination, (2) COVID-19 pregnancy-related anxiety, and 3) generalized anxiety disorder.

    RESULTS: The response rate was 96.6%, with a final number for analysis of 1,272. The majority of our women were Malays (89.5%), with a mean age (standard deviation, SD) of 32.2 (4.6). The maternal vaccine acceptance in our study was 77.1%. Household income (p < 0.001), employment status (p = 0.011), and health sector worker (p = 0.001) were independent predictors of maternal willingness to be vaccinated. COVID-19 infection to self or among social contact and greater COVID-19 pregnancy-related anxiety were associated with increased odds of accepting the SARS-CoV-2 vaccine. Women who rely on the internet and social media as a source of vaccine information were more likely to be receptive to vaccination (adjusted odd ratio, AOR 1.63; 95% CI 1.14-2.33). Strong correlations were observed between maternal vaccine acceptance and the positive perception of (1) vaccine information (p < 0.001), (2) protective effects of vaccine (p < 0.001), and (3) getting vaccinated as a societal responsibility (p < 0.001).

    DISCUSSION: The high maternal vaccine acceptance rate among urban pregnant women in Malaysia is most likely related to their high socio-economic status. Responsible use of the internet and social media, alongside appropriate counseling by health professionals, is essential in reducing vaccine hesitancy among pregnant women.

    Articular cartilage is well known for its simple uniqueness of avascular and aneural structure that has limited capacity to heal itself when injured. The use of three dimensional construct in tissue engineering holds great potential in regenerating cartilage defects. This study evaluated the in vitro cartilaginous tissue formation using rabbit's bone marrow mesenchymal stem cells (BMSCs)-seeded onto poly(lactic-co-glycolic acid) PLGA/fibrin and PLGA scaffolds. The in vitro cartilaginous engineered constructs were evaluated by gross inspection, histology, cell proliferation, gene expression and sulphated glycosaminoglycan (sGAG) production at week 1, 2 and 3. After 3 weeks of culture, the PLGA/fibrin construct demonstrated gross features similar to the native tissue with smooth, firm and glistening appearance, superior histoarchitectural and better cartilaginous extracellular matrix compound in concert with the positive glycosaminoglycan accumulation on Alcian blue. Significantly higher cell proliferation in PLGA/fibrin construct was noted at day-7, day-14 and day-21 (p<0.05 respectively). Both constructs expressed the accumulation of collagen type II, collagen type IX, aggrecan and sox9, showed down-regulation of collagen type I as well as produced relative sGAG content with PLGA/fibrin construct exhibited better gene expression in all profiles and showed significantly higher relative sGAG content at each time point (p<0.05). This study suggested that with optimum in vitro manipulation, PLGA/fibrin when seeded with pluripotent non-committed BMSCs has the capability to differentiate into chondrogenic lineage and may serve as a prospective construct to be developed as functional tissue engineered cartilage.

    BACKGROUND: Plasmodium knowlesi, a simian malaria parasite infection, increases as Plasmodium falciparum and Plasmodium vivax infections decrease in Johor, Malaysia. Therefore, this study aimed to identify the distribution of vectors involved in knowlesi malaria transmission in Johor. This finding is vital in estimating hotspot areas for targeted control strategies.

    METHODS: Anopheles mosquitoes were collected from the location where P. knowlesi cases were reported. Cases of knowlesi malaria from 2011 to 2019 in Johor were analyzed. Internal transcribed spacers 2 (ITS2) and cytochrome c oxidase subunit I (COI) genes were used to identify the Leucosphyrus Group of Anopheles mosquitoes. In addition, spatial analysis was carried out on the knowlesi cases and vectors in Johor.

    RESULTS: One hundred and eighty-nine cases of P. knowlesi were reported in Johor over 10 years. Young adults between the ages of 20-39 years comprised 65% of the cases. Most infected individuals were involved in agriculture and army-related occupations (22% and 32%, respectively). Four hundred and eighteen Leucosphyrus Group Anopheles mosquitoes were captured during the study. Anopheles introlatus was the predominant species, followed by Anopheles latens. Spatial analysis by Kriging interpolation found that hotspot regions of P. knowlesi overlapped or were close to the areas where An. introlatus and An. latens were found. A significantly high number of vectors and P. knowlesi cases were found near the road within 0-5 km.

    CONCLUSIONS: This study describes the distribution of P. knowlesi cases and Anopheles species in malaria-endemic transmission areas in Johor. Geospatial analysis is a valuable tool for studying the relationship between vectors and P. knowlesi cases. This study further supports that the Leucosphyrus Group of mosquitoes might be involved in transmitting knowlesi malaria cases in Johor. These findings may provide initial evidence to prioritize diseases and vector surveillance.

    OBJECTIVE: Facial injury (FI) may occur in isolation or in association with injuries to other parts of the body (facial and other injury [FOI]). The objective of this study was to determine the direct treatment costs incurred during the management of facial trauma.

    MATERIALS AND METHODS: A prospective cohort study on treatment cost for FIs and FOIs due to road-traffic crashes in two university hospitals in Malaysia was conducted from July 2010 to June 2011. The patients were recruited from emergency departments and reviewed after 6 months from the date of initial treatment. Direct cost analysis, comparison of cost and length of hospital stay, and Injury Severity Score (ISS) were performed.

    RESULTS: A total of 190 patients were enrolled in the study, of whom 83 (43.7%) had FI only, and 107 (56.3%) had FOI. The mean ISS was 5.4. The mean length of stay and costs for patients with FI only were 5.8 days with a total cost of US$1,261.96, whereas patients with FOI were admitted for 7.8 days with a total cost of US$1,716.47. Costs doubled if the treatment was performed under general anesthesia compared to local anesthesia.

    CONCLUSION: Treatment of FI and FOI imposes a financial burden on the health care system in Malaysia.
