Second trimester uterine rupture: lesson learned

ntroduction: Uterine rupture is a rare obstetrics catastrophic especially if it occurs during early pregnancy. We experienced three cases of ruptured uterus in the second trimester that first line doctors and obstetrician could learn lessons from. Objectives: To study the presentations and outcome of uterine rupture in the second trimester. Methodology: A retrospective review of uterine rupture in Hospital Tengku Ampuan Afzan from the 1st of April 2010 to the 1st of April 2011. Data obtained from case records, histopathological and autopsy reports. Result: There were 3 cases of uterine rupture. First case, uterine rupture at 15 weeks post sexual intercourse, undiagnosed until postmortem. Second case: ruptured uterus at 24 week diagnosed at laparotomy with the indication of failed medical termination for fetal anomaly. Third case: ruptured uterus at 21 weeks following abdominal massage with initial diagnosis of acute gastroentritis. The final diagnosis was ruptured uterus secondary to placenta percreta, related to medical induction and interstitial pregnancy respectively. Conclusion: Rupture uterus should be considered with or without any risk factors regardless of the gestational age whenever any impression of hemoperitoneum. Intensive surgical method would be needed for accurate diagnosis and immediate management even in early pregnancy is a life saving

Lighting Audit for Energy Conservation and Safety and Health in the Academic Office Building

A lighting audit is an investigational process that measures conditions against standards to determine any lighting improvement measures. The objective of this study is to conduct a lighting audit to evaluate the level of existing lighting in the work environment of the academic faculty building. The lighting audit for the faculty buildings consists of a walk-through audit, lighting desktop work, field data measurement, and lighting analysis. The illuminance level cross-checks with the MS 1525:2019 and the lighting guideline from the Department of Safety and Health Malaysia. The illuminance analysis finding denotes most areas have violated the standards and are in overlit status. Few lighting conservation measures were proposed and prioritized the LED lighting installation. Economic analysis for retrofitting of LED lighting generates energy saving at 30%, a return on investment of two months, and about 6.60-tonne CO2 emission reduction annually. The LED lighting installation shows attractive investment and has good potential at higher luminous efficacy around 40-256 Lm/Watt for the respective areas

Clinical relevance of VKORC1 (G-1639A and C1173T) and CYP2C9*3 among patients on warfarin

What is known and Objectives:  Testing for cytochrome P450-2C9 (CYP2C9) and vitamin K epoxide reductase complex subunit 1 (VKORC1) variant alleles is recommended by the FDA for dosing of warfarin. However, dose prediction models derived from data obtained in one population may not be applicable to another. We therefore studied the impact of genetic polymorphisms of CYP2C9 and VKORC1 on warfarin dose requirement in Malaysia. Methods:  Patients who were attending clinics at our hospital and prescribed warfarin with stabilized INR levels of 2-4 were selected. DNA was extracted from blood samples and subsequently genotyped for CYP2C9*1, *2, *3, VKORC1 (G-1639A) and VKORC1 C1173T. Linear regression modelling using age, CYP2C9 and VKORC1 genotypes, sex, weight and height was undertaken to define a warfarin dosing algorithm. An initial model was developed using data from one cohort of patients and validated using data from a second cohort. Results and Discussion:  A model which included age and variants of CYP2C9 and VKORC1 account for about 37% of the variability in warfarin dose required to achieve INR of 2-4. Among the parameters evaluated, only VKORC1 (G-1639A) and (C1173T) alleles, and age correlated with warfarin dose at 6 month. The mean dose predicted using the algorithm derived from cohort 1 was lower than the actual dose for cohort 2 (3·30 mg, SD 0·84 vs. 3·45 mg, SD 1·42). There was no relationship between INR values and the dose taken by the patients. Race, sex, weight and height did not correlate with dose. What is new and Conclusion:  This study identifies factors which affect warfarin dosing in the Malaysia population. However, our best model does not account sufficiently for the variability in dose requirements for it to be used in dose prediction for the individual patient. Other important influential factors affecting warfarin dose requirement remain to be identified
