Objective: The objective of this study is to determine the antimicrobial effects of MP, AV, and MP + AV in comparison with Ca(OH)2 against E. faecalis, as an intracanal medicament.
Materials and Methods: Antimicrobial activity of MP, AV, MP + AV, Ca(OH)2, and dimethyl sulfoxide was tested against E. faecalis using antimicrobial sensitivity testing, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC). The results were analyzed by Kruskal-Wallis test with Mann-Whitney post hoc test and repeated measures analysis of variance with Bonferroni post hoc test (P < 0.05).
Results: For agar well-diffusion method, MP + AV gave maximum inhibition zone diameter (mean: 8.11 ± 0.015 mm), MP (mean: 6.21 ± 0.046 mm, Ca(OH)2 (mean: 5.5 ± 0.006), and AV (mean: 5.05 ± 0.012) with P < 0.05. MIC for MP + AV was 2 mg/ml, MP at 8 mg/ml, Ca(OH)2 at 8 mg/ml, and AV at 16 mg/ml. The MBC for MP + AV is at 4 mg/ml, MP at 16 mg/ml, Ca(OH)2 at 16 mg/ml, and AV at 32 mg/ml.
Conclusion: The combination of MP and AV consistently showed better antimicrobial activity compared to MP and AV alone against E. faecalis. The findings suggest that MP and AV used in combination may be an ideal intracanal medicament in FET and PET.
MATERIALS & METHODS: Data for subdistricts in Malaysia and radiotherapy services were extracted from Department of Statistics Malaysia and Directory of Radiotherapy Centres (DIRAC). Data from DIRAC were validated by direct communication with centres. Locations of radiotherapy centres, distance and travel time to the nearest radiotherapy were estimated using web mapping service, Google Map.
RESULTS: The average distance and travel time from Malaysian population to the closest radiotherapy centre were 82.5km and 83.4mins, respectively. The average distance and travel were not homogenous; East Malaysia (228.1km, 236.1mins), Central (14.4km, 20.1mins), East Coast (124.2km, 108.8mins), Northern (42.9km, 42.8mins) and Southern (36.0km, 39.8mins). The MV/million population for the country is 2.47, East Malaysia (1.76), Central (4.19), East Coast (0.54), Northern (2.40), Southern (2.36). About 25% of the population needs to travel >100 km to get to the closest radiotherapy facility.
CONCLUSION: On average, Malaysians need to travel far and long to reach radiotherapy facilities. The accessibility to radiotherapy facilities is not equitable. The disparity may be reduced by adding centres in East Malaysia and the East Coast.
METHODS: A cross-sectional study was conducted among the female staff aged 50 years old and above in Health Campus, Universiti Sains Malaysia. The data were collected using a self-administered questionnaire and the Viarad online system. The questionnaires include sociodemographic information, medical factors, knowledge regarding breast cancer and health beliefs about breast cancer. The Viarad online system was used to trace data of mammogram findings for those who underwent mammogram screening.
RESULTS: Among 260 participants, the prevalence of mammogram screening uptake was only 51.9%. By using statistical analysis simple logistic regression and multiple logistic regression, we found that the most significant associated factors were age, clinical breast examination (CBE), level of knowledge and physician recommendation. The mammogram screening showed that most of the breast cancer findings in Breast Imaging Reporting and Data System (BI-RADS) category 2 were at a rate of approximately 35.6%.
CONCLUSION: This study showed the prevalence of mammogram screening uptake among the female staff was 51.9% although the service is free, readily available and accessible. The older age group, CBE, physician recommendation and knowledge about breast cancer were the main associated factors for mammogram screening uptake in the female staff in this hospital. An education programme aimed at improving the knowledge and role of a physician in promoting mammogram screening among staff should be established.
