This study determined the association between nutritional status and the use of protease inhibitors (PI)
containing regimen among HIV-infected children receiving treatment at the referral centres in Klang
Valley. A total of 95 children currently on antiretroviral (ARV) therapy, aged one to eighteen years, were recruited using purposive sampling. Demographic data, anthropometric measurements, medical history, were collected using a structured questionnaire. Serum micronutrients levels and lipid profile were also examined using blood samples. Mean age was 8.8 3.9 years and 44.2% were on PI. Age ( 2 = 10.351, p = .006), weight-for-age ( 2 = 6.567, p = .010), serum selenium ( 2 = 4.225, p = .040) and HDL-C ( 2 = 7.539, p = .006) were significantly associated with the use of PI. Fewer children on PI were deficient in selenium as compared to those not on PI. On the contrary, more children on PI were underweight and had low HDL-C. The use of PI was found to have both positive and negative effects with better selenium level but poorer HDL-C level and weight status.

Zain RB, Khoo SP, Yeo JF

Singapore Dent J, 1995 Jul;20(1):8-10.
PMID: 9582682

A clinical analysis of 304 cases of pyogenic granuloma (excluding pregnancy tumour) were obtained from the clinical evaluations submitted by clinicians while sending specimens for biopsy. The average age of the patients with pyogenic granuloma was 28.9 years with a peak age incidence in the second decade. More female patients were affected and the lesions present mainly in the Chinese. The majority of the lesions were ulcerated and pedunculated. The lesions had a mean diameter of 10.8 mm with a mean lesion duration of 6.0 months. The gingiva was the prevalent site for these lesions with a greater number being located in the maxilla. The recurrence rate was found to be 14.1%.

Ngeow WC, Zain RB, Yeo JF, Chai WL

J Oral Sci, 2000 Mar;42(1):9-14.
PMID: 10808269

This was a retrospective study of odontogenic keratocysts in people from the Singapore-Malaysian region. The purpose of this study was to present the clinicopathologic features of odontogenic keratocysts in the Oriental population and to compare these data with those from other reported studies. Biopsy records from 1981 to 1992 of 61 cases of odontogenic keratocysts from patients in Malaysia and Singapore showed that 42.6% of patients were female and 57.4% of patients were male. Among patients with cysts, 75.4% were Chinese, 6.6% were Malays, 9.8% were Indians and 8.2% were other ethnic groups. The mean age of these patients was 26.98 +/- 15.38 years with a peak incidence occurring in the second to fourth decades. The location of the lesions was more often in the mandible (65.5%) than the maxilla (31.0%). There was a marked predilection for lesions to occur in the posterior mandible. Histologically, 90.2% of the cysts were lined with a para-keratinized stratified squamous epithelium while only 3.3% of the cysts were lined with orthokeratinized stratified squamous epithelium. Mixed para-keratinized and orthokeratinized epithelial linings were observed in 4 cases (6.5%). The cyst linings were mainly uninflamed (95.1%). Inflammation of the cyst wall was found in 42 cases (68.8%). Twelve (19.7%) cases contained keratin in the lumen. A satellite cyst was observed in only 6 cases (9.8%). In conclusion, most clinical and histological features seen in this study were similar to those found for Caucasians. The only clinical feature that was different was the peak age incidence, that ranged from the second to fourth decades, with an absence of a second peak. Odontogenic keratocysts presenting at the site of the dentigerous cyst were observed in 7 cases (11.5%).
Fulltext The health needs and access barriers among refugees and asylum-seekers in Malaysia: a qualitative study

BACKGROUND: In Malaysia, refugees and asylum-seekers are a vulnerable group that often face circumstances in which their health and wellbeing can be compromised. This qualitative study sought to examine the key health concerns and barriers to healthcare access among refugees and asylum-seekers in Malaysia through the lens of healthcare professionals, program staff and experts on refugee and migrant health.
METHODS: We conducted 20 semi-structured in-depth interviews with experts, healthcare professionals, program managers or executives from UN agencies, public healthcare facilities, civil society organizations, and academic institutions in Malaysia. Interviews were transcribed and analyzed both deductively and inductively using thematic analysis.
RESULTS: Participant narratives highlight that the health needs of refugees and asylum-seekers in Malaysia are complex. As reported, access to healthcare is underpinned by numerous social, cultural and economic determinants compounded by a legal environment that lacks inclusivity of refugees and asylum-seekers. Apart from the health risks associated with the migration process, limited access to comprehensive healthcare post-arrival remain a problem for refugees and asylum-seekers in Malaysia. Key barriers to healthcare access are linked to poor health literacy and the lack of awareness on one's right to healthcare; language and cultural differences; protection issues resulting from a lack of legal status; and an inability to afford healthcare due to inadequate livelihoods. Overall, poor access to healthcare is perceived to have detrimental consequences on the health status of refugees, asylum-seekers and its host population, and may incur greater costs to the health system in the long run.
CONCLUSION: Comprehensive efforts in practice and research that tackle the social, cultural and economic determinants of health, and more inclusive health policies are crucial in strengthening healthcare access among refugees and asylum-seekers in Malaysia. Practical recommendations include improving the health literacy of refugees and asylum-seekers for better navigation of the health system; bridging language and cultural gaps through translation support and inter-cultural orientation; implementing policies grounded in the right to healthcare for all regardless of legal status and in the interest of public health; and establishing a larger evidence base to drive policy development and implementation for refugee health within the Malaysian context.

In this paper, the islet autoimmunity status and relation to clinical characteristics, beta cell function and cardio-metabolic risk factors in young-onset Asian diabetic patients are evaluated at baseline. The study population consisted of 912 patients (from China, India, Malaysia and Singapore) with age 12-40 years and diabetes duration <12 months. Autoantibodies to glutamic acid decarboxylase (GADA) and tyrosine phosphatase (IA-2A), beta cell function and cardio-metabolic risk parameters were assessed. Among our young patient cohort, 105 (11.5%) patients were GADA and/or IA-2A positives (Ab +ve). Ab +ve patients were younger, leaner, had more severe hyperglycaemia and lower beta cell function. The frequency of metabolic syndrome was significantly lower in Ab +ve patients (27%) compared to Ab -ve patients (54%). However, a substantial proportion of patients in both groups of patients had atherogenic dyslipidaemia, hypertension and albuminuria (micro or macro). In our study cohort, only one in 10 Asian youth with new-onset diabetes had evidence of islet autoimmunity. At least 60% of Ab +ve and 50% of Ab -ve patients demonstrated classical features of type 1 and type 2 diabetes respectively. Regardless of autoimmunity status, the cardio-metabolic risk factors, in particular atherogenic dyslipidaemia, hypertension and albuminuria were common in our patients with young-onset diabetes.

PMID: 9707784

This survey was undertaken to study the clinical features of trigeminal neuralgia in an Asian population. Demographic data of 44 patients treated at the Dental Faculty of the National University of Singapore and at the University of Malaya were reviewed. The results of the survey were analysed and comparisons made with those of Caucasian patients as reported in other studies where there was a general similarity in the clinical findings. Trigeminal neuralgia presented predominantly in females. Right-sided involvement occurred at a greater frequency, and the peak age at onset was between the sixth and seventh decades of life. The only significant variant in the present sample was the greater involvement of the mandibular branch of the trigeminal nerve rather than the maxillary division. In addition, there was a much greater representation from Chinese patients over Malays as compared with their ratios in the general population.

PMID: 27770180

Backgrounds and aims: The Asian Young Diabetes (ASDIAB) project is a five-year prospective study on the clinical and immunological characterisation of diabetes in newly diagnosed young Asians. This paper aims at evaluating the aetiological classification of diabetes in these patients based on presence/absence of islet autoantibodies and beta cell function at disease presentation and one year.
Materials and methods: A total of 919 patients (from Beijing, Shanghai, Hong Kong, India, Malaysia and Singapore) with age at diagnosis 12-40 years and diabetes duration <12 months were recruited between 1997 and 1999. Complete information on autoantibodies to glutamic acid decarboxylase (GAD) and IA-2 and fasting C-peptide at baseline and 1 year were available in 633 patients. Antibody positivity (Ab+) was defined by presence of GADab and/or IA-2 abo Poor beta-cell function was defined with fasting C-peptide <0.3nM at one year. TlDM was identified in patients Ab+ at diagnosis (irregardless of p cell function status) and in those Ab- at diagnosis and I-year, but demonstrated poor beta-cell function at I-year. Patients who were Ab- at diagnosis and I-year but had good beta cell function (fasting C-peptide >=0.3nM) at I-year were classified as having type 2 diabetes (T2DM).
Results: 139 patients (22%) were classified as having T1DM. Of these, 90 were Ab+ and 49 were Ab- and had poor beta cell function. The remainder 494 patients (78%) were classified as having T2DM. The ethnic distribution of T1DM patients (73% Chinese, 16% Indians and 11 % Malays) was similar to the T2DM. Compared to T2DM, T1DM patients were significantly younger at diagnosis (mean age 28.0 vs 32.9 yrs), leaner (mean BMI 21.5 kg/m' vs 25.9 kg/m' at diagnosis, 22.0 kg/m2 vs 26.1 kg/m2 at 1 year), and had significantly higher HbA1 , (11.8% vs 9.7% at diagnosis; 8.9% vs 8.0% at 1 year) . Median fasting C-peptides were significantly lower in T1DM than T2DM patients (0.2 vs 0.7 nM at diagnosis; 0.2 vs 0.8 nM at 1 year). T2DM were more insulin resistant than T1DM patients as assessed by HOMA index (median 5.8 vs 4.4 at diagnosis, 4.9 vs 3.4 at 1 year).
Conclusions: In Asians with young onset diabetes, assessment at diagnosis and one year for islet autoantibodies (GADab and lor IA-2Aab), together with estimation of p-cell function with fasting serum C-peptide levels, were useful for classifying patients as having T1DM and T2DM .

INTRODUCTION: A cross-sectional study is used to evaluate the lifestyle factors associated with cardiovascular disease (CVD) risk among healthcare workers in tertiary hospitals in Sarawak, Malaysia.
METHODS: A questionnaire-based survey using the Simple Lifestyle Indicator Questionnaire (SLIQ) was administered to, and anthropometric measurements were collected from, 494 healthcare workers.
RESULTS: The mean age of the subjects was 32.4±8.4, with a range of 19 to 59 years. The subjects were from the allied health (45.5%), management and professional (25.1%) and executive (29.4%) fields. Overall, 47.4% of the subjects were of normal weight, 30.2% were overweight, 17.2% were obese and 5.2% were underweight. The mean number of working hours per week for the subjects was 47.6±14.0 with the highest working hours found among the management and professional group, followed by the executive and allied health groups. Overall, 39.7% of the healthcare workers worked office hours, 36.6% worked within the shift system, 20.9% worked office hours and were on-call and the remaining 2.8% worked a mixture of office hours and shifts. Based on the SLIQ score, 58.1% were classified as at intermediate risk for CVD, 38.5% were in the healthy category and 3.4% were in the unhealthy category. Factors associated with a healthier lifestyle were being female (Odds Ratio [OR]= 12.1; CI=3.2-46.4), professional (mean score= 6.70), in the allied health group (mean score=7.33) and in the normal BMI group (OR= 9.3, CI= 1.8-47.0).
CONCLUSION: In our study, healthcare workers had an intermediate risk of developing CVD in the future. Thus, there is a need to intervene in the lifestyle factors contributing to CVD.

AIM: To describe the clinical, biochemical and immunological characteristics of young-onset diabetes in Asia.
METHODS: Clinical, biochemical and immunological variables were assessed in 919 newly diagnosed (duration less than 12 months) young onset Asian diabetic patients aged between 12 and 40 years. The subjects constituted 57% Chinese, 29% Indians and 14% Malays, recruited from diabetes centres in China, Hong Kong, India, Malaysia and Singapore.
RESULTS: The mean age (+/- sd) was 31.6 +/- 7.2 years, with the majority (66%) in the 31-40 years age group. Mean body mass index (BMI) (+/- sd) was 25.3 +/- 5.0 kg/m2 with 47% exceeding the suggested Asian cut-off point for obesity (BMI > or = 25). Ethnic difference in clinical characteristics included BMI, blood pressure, mode of treatment and degree of insulin resistance. Most patients had a clinical presentation of Type 2 diabetes. About 10% had a classical combination of ketotic presentation, presence of autoimmune-markers and documented insulin deficiency indicative of Type 1 diabetes. Forty-eight percent were receiving oral hypoglycaemic agents (OHAs) while 31% were on diet only, 18% were receiving insulin and 2% were on a combination of insulin and OHA.
CONCLUSION: Young onset diabetes patients in Asia represent a heterogeneous group in terms of their clinical and biochemical characteristics and classical Type 1 diabetes is relatively uncommon. The 5-year follow up study will determine the progress of these patients and help to clarify the natural history.
