METHODOLOGY: During this study, enzyme activity was measured in 53/59 (89.8%) hospital-diagnosed G6PD-deficient neonates (34 Malays, 12 Chinese, and seven other ethnic groups) born consecutively in the Kuala Lumpur Maternity Hospital. All neonates, except one, were males.
RESULTS: The mean level of enzyme activity of the 52 males G6PD-deficient neonates (0.47 iu/g Hb, 95% confidence intervals: 0.37, 0.57) was less than 10% of that of normal Malaysian male neonates. The enzyme activity of the only female G6PD-deficient infant, at 1.11 iu/g Hb, was 12.5% of the mean G6PD enzyme activity of normal females.
CONCLUSION: Our results showed that G6PD deficiency in Malaysian neonates predominantly affects males and is usually severe.
METHOD: A prospective observational study of outcome of all VLBW infants born between 1 January 1993 and 30 June 1993 and admitted to the NICU.
RESULTS: Data of 868 VLBW neonates from 18 centres in Malaysia were collected. Their mean birthweight was 1223 g (95% confidence intervals: 1208-1238 g). Thirty-seven point four per cent (325/868) of these infants died before discharge. After exclusion of all infants with congenital anomalies (n = 66, and nine of them also had incomplete records) and incomplete records (n = 82), stepwise logistic regression analysis of the remaining 720 infants showed that the risk factors that were significantly associated with increased mortality before discharge were: delivery in district hospitals, Chinese race, lower birthweight, lower gestation age, persistent pulmonary hypertension of the newborn, pulmonary airleak, necrotizing enterocolitis of stage 2 or 3, confirmed sepsis, hypotension, hypothermia, acute renal failure, intermittent positive pressure ventilation, and umbilical arterial catheterization. Factors that were significantly associated with lower risk of mortality were: use of antenatal steroid, oxygen therapy, surfactant therapy and blood transfusion.
CONCLUSION: The mortality of VLBW infants admitted to the Malaysian NICU was high and was also associated with a number of preventable risk factors.
METHOD: This is prospective and randomized clinical trial. Our study population included 30 eyes undergoing pars plana vitrectomy that required near total corneal debridement intra-operatively for surgical view. We compared the residual wound and wound healing rate in between 3 groups: 10 diabetic eyes (DMV) on topical SH 0.18%; 10 diabetic eyes (DMC) and 10 non-diabetic eyes (NDM) not treated with topical SH 0.18%. The corneal epithelial wound was measured at 12, 24, 36, 48, 60, 72 and 120 h after the vitrectomy surgery.
RESULTS: DMC group had corneal wounds that reepithelialization significantly more slowly than in NDM and DMV groups at 12, 24, 36 and 48 h (Mann-Whitney test p
MATERIALS AND METHODS: Sound extracted human molars were randomly divided into: manufacturer's instructions (MI), manual blend 2 mm (MB2), and manual blend 4 mm (MB4). Occlusal enamel was removed and flattened, dentin surfaces were bonded by Prime & Bond universal (Dentsply and Optibond FL, Kerr). For the MI group, adhesives were applied following the manufacturer's instructions then light-cured. For MB groups, SDR flow+ bulk-fill flowable composite resin was applied in 2- or 4-mm increment then manually rubbed by a micro brush for 15 s with uncured dentine bonding agents and the mixture was light-cured. Composite buildup was fabricated incrementally using Ceram.X One, Dentsply nanohybrid composite resin restorative material. After 24-h water storage, the teeth were sectioned to obtain beams of about 0.8 mm2 for 24-h and thermocycled micro-tensile bond strength at 0.5 mm/min crosshead speed. Degree of conversion was evaluated with micro-Raman spectroscopy. Contraction gaps at 24 h after polymerization were evaluated and atomic force microscopy (AFM) nano-indentation processes were undertaken for measuring the hardness across the interface. Depth of resin penetration was studied using a scanning electron microscope (SEM). Bond strength data was expressed using two-way ANOVA followed by Tukey's test. Nanoindentation hardness was separately analyzed using one-way ANOVA.
RESULTS: Factors "storage F = 6.3" and "application F = 30.11" significantly affected the bond strength to dentine. For Optibond FL, no significant difference in nanoleakage was found in MI/MB4 groups between baseline and aged specimens; significant difference in nanoleakage score was observed in MB2 groups. Confocal microscopy analysis showed MB2 Optibond FL and Prime & Bond universal specimens diffusing within the dentine. Contraction gap was significantly reduced in MB2 specimens in both adhesive systems. Degree of conversion (DC) of the MB2 specimens were numerically more compared to MS1 in both adhesive systems.
CONCLUSION: Present study suggests that the new co-blend technique might have a positive effect on bond strengths of etch-and-rinse adhesives to dentine.
Methods: A cross-sectional, questionnaire-based study was conducted among 103 pharmacists from 74 different community pharmacies to assess their knowledge about the use of herbal medicines and its adverse drug reaction reporting by using a pre-validate knowledge questionnaire consisting of 12 questions related to it. The pharmacists' responses were measured at a 3-point Likert scale (Poor=1, Moderate=2, and Good=3) and data was entered in SPSS version 22. The minimum and maximum possible scores for knowledge questionnaires were 12 and 36 respectively. Quantitative data was analyzed by using One Way ANOVA and Paired t-test whereas Chi-square and Fisher exact test were used for qualitative data analysis. A p-value of less than 0.05 was considered statistically significant for all the analyses.
Results: About 92% of the pharmacist had good knowledge regarding the use of herbal medicines and its adverse drug reaction reporting with a mean knowledge score of 32.88±3.16. One-way ANOVA determined a significant difference of employment setting (p<0.043) and years of experience (<0.008) with mean knowledge scores of Pharmacists. Pharmacists' knowledge was significantly associated with their years of experience with the Chi-square test.
Conclusion: Pharmacists exhibit good knowledge regarding the use of herbal medicines and its adverse drug reaction reporting. However, with an increasing trend of herbal medicine use and its adverse drug reaction reporting it recalls the empowerment of experienced pharmacists with training programs in this area for better clinical outcomes.
