South East Asia has 8% of world population, but only has 2% of the total number of neurologists in the world. Seven of the 11 countries in South East Asia have training programmes in Neurology. Brunei, Laos, Malaysia, Myanmar and Singapore require prior training and certification in Internal Medicine before admission to training to Neurology. Most training programmes are 3 years in duration, inclusive of mandatory rotation to clinical neurophysiology. Assessment and certification processes are vigorous in most countries. Mature age, lack of funding, inadequate direct clinical responsibilities, and poor literacy in English are other issues in some of the countries. There is need to improve the quality as well as quantity in the training of neurologists in the region.

The standardized management of acupuncture-moxibustion in Singapore General Hospital is introduced. With gradual improvement of outpatient infrastructure, re-training of medical staff, strict disinfection of manipulation, periodical inspection of medical instruments, unified management of writing, saving and processing in medical records and public education of TCM knowledge, a standardized management system in accordance with modernized hospital is gradually established. As a result, efficiency and quality of clinical treatment is continuously increasing. From April of 1998 to December of 2012, a total of 74 654 times of treatment were performed, and treatment amount per day is gradually increased. The unusual condition of acupuncture is avoided. Periodical strict inspection of joint committee authenticated by domestic and overseas medical health organization is repeatedly passed and accepted. Additionally, three clinical researches funded by Singapore Health-care Company are still in progress in acupuncture-moxibustion department.

INTRODUCTIONThe aim of this study was to assess the sensitivity of McDonald's magnetic resonance imaging (MRI) criteria for the diagnosis of multiple sclerosis (MS) in a group of Asian patients diagnosed with clinically definite MS, based on lesion characterisation on MRI scans.
MATERIALS AND METHODSForty-nine patients from 3 major neurological institutions were classified as having Asian- or Western-type MS based on clinical assessment. Each MRI scan was reviewed by 2 neuroradiologists for the presence and characteristics of brain and spinal lesions. The McDonald's MRI criteria were then applied and its sensitivity evaluated.
RESULTSNine patients were excluded, leaving 34 females and 6 males who were dominantly Chinese (90%), with a mean age of 36.2 years. The MRI brain and spinal findings were detailed and tabulated. Statistically significant differences (P <0.01) in MRI brain findings and sensitivity of McDonald's MRI criteria were found between our Asian- and Western-type MS patients. The diagnostic yield of McDonald's MRI criteria increased by 20% when we substituted a cord for a brain lesion, and applied the substitution for enhancing cord lesions as well.
CONCLUSIONThe diagnosis is more likely to be made when using McDonald MRI criteria based on brain findings, in a patient who presents clinically with Western-type MS. The provision for substitution of "one brain for a spinal lesion" is helpful in Asian-type MS, where there is preponderance of spinal lesion load. Our findings suggest that minor modifications in the interpretation of McDonald's MRI criteria have significant impact on the diagnosis in patients clinically presenting as Asian-type MS, with potential bearing on their subsequent management.

INTRODUCTIONNot much is known regarding how primary care physicians (PCPs) in Singapore keep themselves healthy and mitigate ill health. This study aims to determine the health-seeking behaviour of local PCPs and to identify the predictors of local PCPs attaining the recommended level of exercise.
METHODSThis study was a cross-sectional questionnaire survey, which included questions on the demographic characteristics, practice profiles and health-seeking behaviour of PCPs. The sampling frame was the 1,400 listed members of the College of Family Physicians Singapore. The anonymised survey was executed in two phases: a postal survey, followed by a web-based survey on the College of Family Physicians Singapore website. The two data sets were collated; the categorical variables, summarised; and the differences between subgroups (based on exercise engagement), compared using Fisher's exact test. The effect of each risk factor on exercise duration was quantified using odds ratio (OR) estimate and 95% confidence interval (CI). Multivariate logistic regression analysis was performed to identify significant predictors of exercise engagement.
RESULTSA total of 631 PCPs participated in the survey--26% were ≤ 34 years old, 58% were male, 21% were single, 34% were singleton practitioners, and 56% were private practitioners. The percentage of PCPs who exercised ≥ 2.5 hours weekly was 29%, while 28% exercised < 0.5 hours weekly. Of the PCPs surveyed, 1% currently smoke, 0.8% drink more than 14 units of alcohol weekly, 60% undertook health screening, 65% had blood investigations done, and 64% had taken preventive measures such as getting influenza vaccination.
CONCLUSIONWhile local PCPs generally did not have undesirable habits such as smoking and alcohol abuse, they could further increase their exercise intensity and undertake more preventive measures such as getting vaccinated against various diseases.

Shone complex is a rare congenital disorder that involves 4 obstructive lesions of the left heart, as follows: parachute mitral valve, supravalvular mitral ring, subaortic stenosis, and coarctation of the aorta. Incomplete forms with 2 or 3 of these lesions in adult patients have been rarely reported in the literature, meaning that insufficient general data exist concerning the surgical strategy and clinical follow-up. Herein, we report the case of a 31-year-old woman with a diagnosis of incomplete form of Shone complex with parachute mitral valve and coarctation of the aorta who underwent successful single-stage surgical repair.

Background:
It is generally agreed that using a bilateral internal thoracic artery (BITA) composite graft improves long-term survival after coronary artery bypass grafting (CABG). Although the left internal thoracic artery (LITA)-based Y-composite graft is widely adopted, technical or anatomical difficulties necessitate complex configurations. We aimed to investigate whether BITA configuration impacts survival or patency in patients undergoing coronary revascularization.
Methods:
Between January 2006 and June 2017, 1,161 patients underwent CABG at Seoul National University Bundang Hospital, where the standard technique is a LITA-based Y-composite graft with the right internal thoracic artery (RITA) sequentially anastomosed to non-left anterior descending (LAD) targets. Total of 160 patients underwent CABG using BITA with modifications. Their medical records and imaging data were reviewed retrospectively to investigate technical details, clinical outcomes, and graft patency.
Results:
Modifications of the typical Y-graft (group 1, n=90), LITA-based I-graft (group 2, n=39), and RITA-based composite graft (group 3, n=31) were used due to insufficient RITA length (47%), problems using LITA (28%), and target vessel anatomy (25%). The overall 30- day mortality rate was 1.9%. Among 116 patients who underwent computed tomography or conventional angiography at a mean interval of 29.9±33.1 months postoperatively, the graft patency rates were 98.7%, 95.3%, and 83.6% for the LAD, left circumflex artery, and right coronary artery territories, respectively. Patency rates for the inflow, secondary, and tertiary grafts were 98.2%, 90.5%, and 80.4%, respectively. The RITA-based graft (group 3) had the lowest patency rate of the various configurations (p<0.011).
Conclusion
LITA-based Y composite graft, showed satisfactory clinical outcomes and patency whereas modifications of RITA- based composite graft had the lowest patency and 5-year survival rates. Therefore, when using RITA-based composite graft, other options should be considered before proceeding atypical configurations.
