The study was conducted to determine the pick-up rate of abnormal cervical smears and the prevalence rate of cervical cancer in women aged 60 years and above and the demographic characteristics of the women screened. The pick-up rate of abnormal cervical smears was 1.65%. The prevalence rate for cervical intraepithelial neoplasia and frank carcinoma was 6.4 and 5.0 per thousand women screened respectively. The study group comprised 89.7% Chinese, 4.7% Malays, 3.6% Indians and 2.0% Others. The pick-up rate of abnormal smears was 1.9% in the Chinese and 1.3% in the Indians. There were no abnormal smears in the Malays and Others. The results demonstrate the importance of a routine cervical cancer screening programme among elderly women aged 60 years and above in Singapore.
The aim of this study was to compare the response and survival rates of term infants with persistent pulmonary hypertension of the newborn (PPHN) on high frequency oscillatory ventilation (HFOV) treated with either inhaled nitric oxide (iNO) or intravenous magnesium sulphate (MgSO4).
Introduction: The aim of this study was to determine predictors of failed closure of patent ductus arteriosus (PDA) following a single course of indomethacin in symptomatic preterm infants.
Methods: This prospective observational study was carried out on 60 preterm infants weighing less than 1,750 g with symptomatic PDA confirmed by echocardiography. At a median age of 7.0 days (interquartile range 4.0), they were given indomethacin of 0.1 mg/kg/day intravenously daily for six days. Closure of PDA was reassessed by echocardiography upon completion of therapy.
Results: The PDA of 40 percent (n=24) of these infants remained patent. Forward logistic regression analysis showed that the only significant predictors of failed PDA closure in these infants were: PDA size (adjusted odds-ratio [OR] is 7.0; 95 percent confidence interval [CI] of OR is 2.0, 24.8; p-value is 0.002), birth weight (adjusted OR is 0.996; 95 percent CI of OR is 0.993, 1.000; p-value is 0.03) and platelet count (adjusted OR is 0.987; 95 percent CI is 0.975, 1.000; p-value is 0.045). Gestational age, maternal age and left atrium/aorta ratios were not significant predictors.
Conclusion: Larger PDA, lower birth weight and lower platelet count were significant predictors of high failure in indomethacin therapy given late at one week of life.
The clinical features and pathology of 17 patients with gastrointestinal lymphoma are reviewed. The small intestine was the site most commonly involved. Emergency presentation was usual: 11 of the 17 patients presented as acute abdomen or gastrointestinal haemorrhage. The frequency of gastrointestinal lymphoma to carcinoma in the Chinese and Indians was comparable to that in the West but a higher frequency was found in the Malays and Orang
Asli.
The Breast Module (BR23) is increasingly being used worldwide in breast cancer research. This study evaluates the appropriateness of the translated version (i.e. BR23-Malay version) as a useful tool for the Malaysian population who could understand Malay, and examines the reliability and validity of the BR23-Malay version.
Sabah, formerly known as North Borneo, is part of East Malaysia. 52.2 percent of patients with breast cancer in Sabah presented at advanced stages and up to 20.4 percent of patients defaulted proper treatment, opting for traditional therapy. We performed a two-year prospective study looking at the treatment trends of breast cancer in Sabah.
This paper illustrates the role of 99m-Technetium(Tc) diethyl-iminodiacetic acid (EHIDA) hepatobiliary scintigraphy in a patient who developed obstructive jaundice as a result of afferent loop syndrome, which is a rare occurrence. The computed tomographic (CT) and ultrasonographic findings are also described.
With an increasing number of women undergoing breast screening, an effective method of removing non-palpable lumps detected by mammography or sonography is by hookwire localisation excision biopsy (HWLB). The aim of this paper was to audit the practice of HWLB at the University Malaya Medical Centre.
We report our experience on the use of fibreoptic bronchoscopy in the diagnosis of pulmonary tuberculosis. The case records of 1,274 patients who underwent fibreoptic bronchoscopy at the National Tuberculosis Centre, Kuala Lumpur, Malaysia during a three-year period were reviewed. In 120 of them the final diagnosis was tuberculosis. Bronchoscopy confirmed the diagnosis in 37 patients (30.8%). This was achieved by bronchial aspiration for culture in 26 patients (70.3%) and bronchial biopsy for histopathology in 11 patients (29.7%). It was the exclusive method of confirmation in 16 patients (13.3%). Sputum culture was positive in 62 patients (51.7%) including 41 patients (34.2%) in whom bronchoscopy was unhelpful. Six patients had diagnosis confirmed by other means while in 36 others (30%) it was based on clinical features and supportive basic investigations. There were no complications noted. We conclude that while sputum examination remains the mainstay for diagnosing pulmonary tuberculosis, fibreoptic bronchoscopy serves as a safe and useful adjunct.

AIM: To evaluate the anthropometric measurements and dietary intake of the free-living elderly in a Chinese community.
METHOD: A survey was carried out on 48 male and female subjects aged 60 to 96 years using anthropometric, dietary intake and questionnaire techniques.
RESULTS: The study indicated female subjects to have more health problems, like pain at the joints (33%), hypertension (17%) and diabetes (27%) as compared to the male subjects. Dietary intake analysis showed the Chinese male subjects to have a higher energy intake (1,623 kcal) compared to the females (1,197 kcal) even though they did not fulfill the recommended dietary intake. The intake for energy, fats and carbohydrates, was found to be significantly different (p < 0.05) between both sexes. Anthropometric measurements indicated male elderly subjects to be significantly heavier (p < 0.05, 55.4 kg) and taller (161.8 cm) than female elderly subjects (49.5 kg; 146.2 cm respectively). About half of the elderly were normal in their BMI (male 55.6%; female 50%) and only 6.6% of the female subjects were obese. More male subjects were found to be underweight (33%) compared to female subjects (17%). Waist hip ratio was 0.92 for male and 0.87 for female.
CONCLUSION: Our study showed that female elderly subjects had more health problems compared to male elderly subjects. On the whole, the elderly did not fulfill the recommended amount for energy intake while the percentage for carbohydrates, fats and protein from the total calorie intake were not in accordance with the healthy diet guidelines. Anthropometrically, male subjects were heavier and taller than female subjects. Looking at body mass index, most of the male elderly subjects were in the normal to underweight range. With these results, more research is warranted to give a clearer picture of the Chinese elderly in the country.

In childhood acute lymphoblastic leukaemia (ALL), cytogenetics play an important role in diagnosis, allocation of treatment and prognosis. Conventional cytogenetic analysis, involving mainly karyotyping in our experience, has not been successful in a large proportion of cases due to inadequate metaphase spreads and poor chromosome morphology. Our aim is to develop a highly sensitive and specific method to screen simultaneously for the four most frequent fusion transcripts resulting from specific chromosomal translocations, namely, both the CML- and ALLtype BCR-ABL transcripts of t(9;22), E2A-PBX1 transcript of t(1;19), the MLL-AF4 transcript of t(4;11) and TEL-AML1 (also termed ETV6-CBFA2) of the cryptic t(12;21). A multiplex reverse transcription polymerase chain reaction protocol (RT-PCR) was developed and tested out on archival bone marrow samples and leukaemia cell lines. In all samples with a known translocation detected by cytogenetic techniques, the same translocation was identified by the multiplex-PCR assay. Multiplex RT-PCR assay is an effective, sensitive, accurate and cost-effective diagnostic tool which can improve our ability to accurately and rapidly risk-stratify patients with childhood ALL.
INTRODUCTION: Obesity is a major modifiable risk factor associated with most chronic diseases. The aim of this study was to determine the prevalence of obesity, and its associated risk factors, among apparently healthy Chinese adults in a Malaysian suburban village.
METHODS: This was a cross-sectional study conducted among the Chinese residents in Seri Kembangan New Village, Klang Valley, Selangor, Malaysia. Convenience sampling was used for the selection of participants. Body weight, height, waist and hip circumferences, and blood pressure were measured. Fasting venous plasma was drawn for the measurement of fasting glucose level and lipid profile. Data on sociodemographic factors, dietary habits, physical activity, perceived stress level and sleep duration were collected using interviewer-administered, pretested and validated questionnaires.
RESULTS: Among the 258 Chinese residents (mean age 41.4 ± 10.0 years) recruited, the prevalence of obesity was 40%. The obese participants had significantly higher mean blood pressure, and triglyceride and fasting plasma glucose levels than the non-obese participants (p < 0.05). The obese participants also had a significantly lower high-density lipoprotein cholesterol level than the non-obese participants. Logistic regression analysis showed that drinking soy milk (adjusted odds ratio [OR] 0.447; 95% confidence interval [CI] 0.253-0.787; p < 0.05) and the perception that a balanced diet consists mainly of vegetables (adjusted OR 0.440; 95% CI 0.215-0.900; p < 0.05) were associated with a reduced risk of obesity. The risk of obesity was higher in younger participants (adjusted OR 2.714; 95% CI 1.225-6.011; p < 0.05).
CONCLUSION: The prevalence of obesity was high among the apparently healthy suburban Chinese. Our findings suggest that soy milk consumption and the perception that a balanced diet consists mainly of vegetables are associated with a lower risk of developing obesity in this population.
Nevus lipomatosus superficialis is a rare benign skin malformation characterised by ectopic adipocytes in the upper dermis. It is classified into two types: a classical Hoffman-Zurhelle type and the solitary type. A case of the classical type with multiple soft, non-tender, pedunculated, cerebriform, skin-coloured papules and nodules over the right lower back is presented in a 21-year-old Malay woman. She had a rare occurrence of ulceration and necrosis of the lesions.
Immunoglobulin G, A and M levels were determined in paired maternal and cord sera of premature, full term and postmature newborns of urban dwelling Chinese, Indian, Malay and full term newborn of the forest dwelling Orang Asli (Malaysian aborigines). The mean serum IgC level in the full term Orang Asli newborns (1254±441 mg per 100 mil is comparable to that of the Indians (1211±282 mg per 100 ml) and Malays (1169±286 mg per 100 ml) but these levels are higher than those of the Chinese
newborns (1092±270 mg per 100 ml). Statistical analysis indicates a significant dependence of cord serum IgG level on maternal serum IgG level in the . Chinese, Indians and Malays. In addition, in Indians the cord serum IgG was significantly dependent at 5% level on the gestation age. The fetomaternal serum IgG level ratios at term were equal to or just less than one. The cord serum IgM levels of the Chinese, Indian, Malay and Orang Asli newborns at term were 11.6.±. 6.5, 12.5.±. 7.3, 10.9.±. 5.8 and
16.7±6.9 mg per 100 ml respectively. Statistical analysis showed absence of correlation between cord serum IgM level and birthweight, gestation age or maternal serum IgM level in Chinese and Malays. In Indians the cord sera IgM level showed a dependence on the birthweight. Immunoglobulin A was present in 34.6%, 40.5%, 31.6% and 62.5% of full term Chinese, Indian, Malay and Orang Asli newborns respectively. These observations are discussed in relation to the immunoglobulin levels observed in populations residing in temperate and other tropical regions.
The birth weight distribution, mean birth weight and incidence of LBW amongst the various ethnic groups in Malaysia is described briefly. The data collected and analysed is hospital data where all deliveries in 1980 were analysed. The mean birth weight showed that the Chinese had the highest Mean Birth Weight amongst the three ethnic groups and the Indians had the lowest mean birth weights. The overall incidence of LBW was 11.8% and the Malay and Indian babies constituted the high
incidence of LBW whereas the Chinese had a low incidence of LBW babies in the study. Amongst the various ethnic groups the Indians had a higher incidence of LBW compared to the Chinese and Malays.
The traditional birth attendant (bidan kampong) or the TBA is still responsible for a substantial number of deliveries in Peninsular Malaysia. In the study area, the TBA s were responsible for about 47.2% of the deliveries in 1976. They were also responsible tor a substantial number of maternal deaths in the district. Therefore it was decided to identity and train the TBAs to identity ‘at risk’ cases at mothers and children and refer them to the nearest health facility. The TBA s were trained to use simple hygenic and aseptic procedures. At the end oi their training all at them were presented with a UNICEF midwifery kit. The short training proved useful because they now deliver fewer ‘at risk' cases and there is an in- creasing trend among them to refer the ‘at risk’ cases to the hospitals. The utilizations of TBA s in the maternal and child health program is a useful tool for the attainment at primary health care objective for developing countries by the year 2000.
INTRODUCTION: Peripheral diabetic neuropathy, which is a cause of increasing morbidity and mortality following foot ulcers and amputations, is a burden to health and the economy. Various adjunct treatments to improve neuropathy have been introduced into the market; one such treatment is monochromatic infrared energy (MIRE) therapy, which claimed to produce promising results. This study aimed to evaluate the effects of MIRE on diabetic feet with peripheral neuropathy.
METHODS: A randomised controlled, single-blinded study was conducted at Hospital Universiti Sains Malaysia from February 2008 to October 2008. A total of 30 feet from 24 patients were studied. Neuropathy was screened using the Michigan neuropathy scoring instrument, followed by an assessment of the current perception threshold using a neurometer at frequencies of 2,000 Hz, 250 Hz and 5 Hz. The feet were randomised to receive either daily MIRE or sham treatment for a total of 12 treatments. Each foot was then reassessed using the neurometer at six weeks and three months following treatment.
RESULTS: The data obtained was analysed using a non-parametric test to compare the pre- and post-treatment groups. No significant difference was found between the neuropathic foot of diabetic patients in both the MIRE and sham groups.
CONCLUSION: No improvement of neuropathy was observed following MIRE treatment in the neuropathic feet of diabetic patients.
