Disseminated Penicillium marneffei infection: a report of five cases in Singapore

Kurup A, Leo YS, Tan AL, Wong SY

Ann Acad Med Singap, 1999 Jul;28(4):605-9.
PMID: 10561784

Penicillium marneffei has emerged as an important opportunistic pathogen in HIV-infected patients in Southeast Asia. We report the first 5 cases of P. marneffei diagnosed in Singapore. All the patients were HIV-infected and were either Thai nationals or had frequently travelled to Thailand. Fever, weight loss, anaemia and papular skin lesions were common clinical manifestations in our patients, all of whom had the organism isolated from blood. Skin biopsy specimens showed histological evidence of P. marneffei in 2 patients. In 1 patient each, the organism grew in cultures of specimens from bone marrow and respiratory secretions. Amphotericin B therapy followed by itraconazole were used in 3 of our 5 patients and was associated with good clinical response and outcome.

Myocardial infarction in Singapore: a nationwide 10-year study of multiethnic differences in incidence and mortality

Tan AT, Emmanuel SC, Tan BY, Teo WS, Chua TS, Tan BH

Ann Acad Med Singap, 2002 Jul;31(4):479-86.
PMID: 12161884

INTRODUCTION AND METHODS: Cardiovascular diseases have progressively increased in importance as a major contributor of morbidity and mortality in Asia. However, many countries in Asia do not have nationwide systematically-collected and standardised data on myocardial infarction (MI). To accurately document the extent of atherosclerotic coronary heart disease in Singapore, a nationwide myocardial infarct registry was established in the mid-1986. Possible myocardial infarct events were identified through daily national lists of cardiac enzymes, hospital discharge codes, mortuary records and the national death registry. Data obtained from clinical history, cardiac enzymes and 12-lead electrocardiogram Minnesota codes were entered into an algorithm based on the WHO MONICA study. Cases identified as "definite" MI were included in the decade's review for this study.
RESULTS: From 1988 to 1997, 13,048 myocardial infarct events were diagnosed with 3367 deaths. There was a 39.1% decline in mortality, with an average decline of 6.5% per year [95% confidence intervals (CI), -3.9% to -9.1%]. However, the decline in incidence was only 20.8% with an average decline of 2.4% per year (95% CI, -6.6% to -1.2%). The highest incidence and mortality rates for both genders were seen in the Indians, followed by the Malays and the Chinese.
CONCLUSION: Over 10 years, from 1988 to 1997, we documented a significant fall in mortality from MI in Singapore. There was a smaller decline in the incidence of infarction. Singapore implemented a National Healthy Lifestyle Programme in 1992 as a 10-year effort. The disparity in the incidence and mortality may suggest that a more dramatic and immediate impact has taken place in mortality through therapeutic programmes; primary preventive programmes would be more difficult to evaluate and have a more gradual impact. Only with continual accurate data collection through the whole country, over a much longer period, can the relative value of preventive and therapeutic programmes in coronary heart disease be assessed.

Incidence of ischaemic heart disease and stroke in Chinese, Malays and Indians in Singapore: Singapore Cardiovascular Cohort Study

Heng DM, Lee J, Chew SK, Tan BY, Hughes K, Chia KS

Ann Acad Med Singap, 2000 Mar;29(2):231-6.
PMID: 10895345

INTRODUCTION: This is the first prospective cohort study in Singapore to describe the incidence of ischaemic heart disease (IHD) and stroke among Chinese, Malays and Asian Indians.
MATERIALS AND METHODS: The Singapore Cardiovascular Cohort Study is a longitudinal follow-up study on a general population cohort of 5920 persons drawn from 3 previous cross-sectional surveys. Morbidity and mortality from IHD and stroke were ascertained by record linkage using a unique identification number with the death registry, Singapore Myocardial Infarct Registry and in-patient discharge databases.
RESULTS: There were 193 first IHD events and 97 first strokes during 52,806 person-years of observation. The overall incidence of IHD was 3.8/1000 person-years and that of stroke was 1.8/1000 person-years. In both males and females, Indians had the highest IHD incidence, followed by Malays and then Chinese. For males after adjusting for age, Indians were 2.78 times (95% CI 1.86, 4.17; P < 0.0001) and 2.28 times (95% CI 1.34, 3.88; P = 0.002) more likely to get IHD than Chinese and Malays respectively. For females after adjusting for age, Indians were 1.97 times (95% CI 1.07, 3.63; P = 0.03) and 1.37 times (95% CI 0.67, 2.80; P = 0.39) more likely to get IHD than Chinese and Malays respectively. For stroke, male Chinese and Indians had higher incidence than Malays (though not statistically significant). However, in females, Malays had the highest incidence of stroke, being 2.57 times (95% CI 1.31, 5.05; P = 0.008) more likely to get stroke than Chinese after adjustment for age.
CONCLUSIONS: This prospective study of both mortality and morbidity has confirmed the higher risk of IHD in Indians. It has also found that Malay females have a higher incidence of stroke, which deserves further study because of its potential public health importance.

Refractory seizures in a young army cohort

Loh NK, Lee WL, Yew WW, Tjia TL

Ann Acad Med Singap, 1997 Jul;26(4):471-4.
PMID: 9395813

This survey covered male Singapore citizens born in 1974 who were medically screened at the age of 18 years before enlistment for compulsory military service. Suspected epileptics were referred to government hospitals for further management. Out of 20,542 men, there were 121 epileptics, giving a cumulative incidence of 5 per 1000 by age 18 years. We had information on 106 (87%) of these individuals and were able to interview them and review their hospital records. Seventy-three of the 106 (69%) epileptics had generalised seizures while 14 (13%) had refractory seizures. There was no statistically significant racial bias amongst these epileptics. Unprovoked afebrile seizures occurred early in these patients, half of whom had seizures onset before 7 years of age. Nine refractory epileptics had a history of febrile seizures, 4 of which were complex febrile seizures. Magnetic resonance imaging identified mesial temporal sclerosis in 2 patients and a hypothalamic lesion in 1 patient. Computed tomographic scans revealed focal cortical atrophy in 2 patients. Nine other patients had normal imaging studies. Nine out of 14 (64%) patients with refractory epilepsy had partial seizures; 4 (29%) had generalised seizures and 1 (7%) was unclassified. This is in contrast to the distribution of the entire cohort of epileptics studied. Two out of 9 patients with refractory partial seizures (gelastic epilepsy and mesial temporal sclerosis) had undergone surgery while 6 of the other 7 patients refused to consider surgery.

Plasma vitamins A, C and E in the general population of Singapore, 1993 to 1995

Hughes K, New AL, Lee BL, Ong CN

Ann Acad Med Singap, 1998 Mar;27(2):149-53.
PMID: 9663300

The National University of Singapore Heart Study measured cardiovascular risk factors, including selected plasma vitamins, on a random sample of the general population aged 30 to 69 years. Plasma vitamins A and E were normal and similar by ethnic group. Mean plasma vitamin A levels were: Chinese (males 0.68 and females 0.52 mg/L), Malays (males 0.67 and females 0.54 mg/L), and Indians (males 0.66 and females 0.51 mg/L). Mean plasma vitamin E levels were: Chinese (males 12.6 and females 12.6 mg/L), Malays (males 13.6 and females 13.3 mg/L), and Indians (males 12.9 and females 12.8 mg/L). No person had plasma vitamin A deficiency (< 0.01 mg/L) and only 0.1% had vitamin E deficiency (< 5.0 mg/L). In contrast, plasma vitamin C was on the low side and higher in Chinese than Malays and Indians. Mean plasma vitamin C levels were: Chinese (males 6.3 and females 8.4 mg/L), Malays (males 5.1 and females 6.4 mg/L), and Indians (males 5.7 and females 6.9 mg/L). Likewise, the proportions with plasma vitamin C deficiency (< 2.0 mg/L) were lower in Chinese (males 14.4 and females 0.7%), than Malays (males 19.7 and females 7.2%), and Indians (males 17.8 and females 11.0%). Relatively low levels of plasma vitamin C may contribute to the high rates of coronary heart disease and cancer in Singapore. In particular, lower plasma vitamin C in Malays and Indians than Chinese may contribute to their higher rates of coronary heart disease. However, plasma vitamin C does not seem to be involved in the higher rates of cancer in Chinese than Malays and Indians. The findings suggest a relatively low intake of fresh fruits and a higher intake is recommended. Also, food sources of vitamin C may be destroyed by the high cooking temperatures of local cuisines, especially the Malay and Indian ones.

Pulmonary function in healthy Chinese, Malay and Indian adults in Singapore

Chia SE, Wang YT, Chan OY, Poh SC

Ann Acad Med Singap, 1993 Nov;22(6):878-84.
PMID: 8129348

Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow rate (PEFR), single-breath diffusion capacity measurements (effective alveolar volume (VA), carbon monoxide transfer factor (DLCO) and transfer coefficient (KCO)) were determined in 452 healthy Singaporean adults (277 males and 175 females) aged 20-70 years. The ratio of Chinese, Malay and Indian subjects was 5:2:3 in both sexes. Age, height and weight in the males were all significantly correlated with FEV1, FVC, DLCO, VA and PEFR. However, for females, only age and height were significantly correlated with the studied lung function parameters. Significant ethnic differences were observed for most of the pulmonary functions (except KCO and PEFR) among the Chinese, Malays and Indians for both males and females. The predicted FEV1 and FVC values (specific age and height) for both sexes were highest among the Chinese followed by the Malays than Indians, in that order. Regression equations, with age and height as independent variables, were derived for males and females in each ethnic group to predict normal pulmonary function for the Singapore Chinese, Malay and Indian populations. The predicted values of various pulmonary function measurements obtained from these regression equations for subjects of specified age (30 years) and height (165 cm for men, 155 cm for women) were compared with those reported in other studies. Differences were observed among the different races.

Epidemiology of chronic (perennial) rhinitis in Singapore: prevalence estimates, demographic variation and clinical allergic presentation

Ng TP, Tan WC

Ann Acad Med Singap, 1994 Jan;23(1):83-8.
PMID: 8185279

We conducted a population-based study involving a stratified cluster disproportionate random sample of 2868 adults aged 20 to 74 years selected from five housing estates (Yishun, Toa Payoh, Jurong East, Geylang/Eunos and Bukit Merah). Chronic rhinitis was defined as the usual presence of symptoms of blocked or running nose, apart from colds or the flu, lasting for more than a year. Allergic rhinitis was considered to be present if these symptoms were associated with conjunctivitis or recognisable provocation by commonly known allergens, namely house dust, dogs, cats, birds, pollen, or medicines. The estimated general population prevalence of chronic rhinitis was 10.8% (95% confidence interval (CI) 8.8-12.7). Higher prevalences were noted in males, in younger adults, in Indians and Chinese, in those with higher socio-economic status, and in Toa Payoh, Jurong East and Geylang/Eunos. The prevalence of allergic rhinitis was 5.5% (95% CI 4.5-6.5). The most common 'allergenic' factor in allergic rhinitis was house dust (73%); provocation by birds, cats or dogs (5%), grass or tree pollens (5%), and medicine (5%) was less common but likely to have been under-recognised. Provocation by change in temperature (54%) and early in the morning (64%) was equally frequent in both 'allergic' and 'non-allergic' rhinitis; cigarette smoke, petrol and diesel fumes, food and work environment were less common (4-12%). Allergic rhinitis was highly significantly associated with asthma (13.9% in allergic rhinitis, 4.4% in non-allergic rhinitis, and 2.2% in non-rhinitic subjects).

Clinical presentation and disease associations of gout: a hospital-based study of 100 patients in Singapore

Koh WH, Seah A, Chai P

Ann Acad Med Singap, 1998 Jan;27(1):7-10.
PMID: 9588267

The aim of this retrospective study was to characterise the clinical presentation and disease associations of Oriental patients with gout seen in our hospital over a six-month period. One hundred patients comprising of 77 males and 23 females [89% Chinese, 7% Malays, 2% Indians and 2% others; mean age was 50.9 years (range 18 to 82 years), mean age at onset of disease was 43.7 years (range 16 to 78 years)] were studied. The disease was familial in 18% and 44% of patients had a history of alcohol ingestion. Co-morbid conditions included hypertension (36%), hyperlipidaemia (25%), renal failure (17%), ischaemic heart disease (13%), diabetes mellitus (4%), systemic lupus erythematosus (3%), psoriasis (2%) and ankylosing spondylitis (1%). The majority of patients (68%) had at least one associated disease. At the onset of disease, the joints commonly involved were the ankles (39%) and knees (27%) whilst the first metatarsophalangeal (MTP) joint was affected in only 26% of cases. Polyarticular onset was uncommon (n = 6). The precipitating factors reported by the patients included food (n = 23), alcohol (n = 12), drugs (n = 4), trauma (n = 3) and surgery (n = 2). Eleven patients had a history of renal calculi and 15% had tophaceous gout. Majority of patients (71%) had been treated with urate-lowering drugs (allopurinol). We concluded that gout in Singapore predominantly affects middle-aged men who often have an accompanying illness.

Ankylosing spondylitis in Singapore: a study of 150 patients and a local update

Koh WH, Boey ML

Ann Acad Med Singap, 1998 Jan;27(1):3-6.
PMID: 9588266

This paper presents the results of a clinical study of 150 patients in Singapore with ankylosing spondylitis (AS) and reviews recent developments locally with regards to the disease. The patients were predominantly males (ratio 7:1) and Chinese (n = 147). The onset of disease is usually in the early twenties and there was a mean delay of 6.3 years before diagnosis was made. Peripheral joint involvement is common but apart from uveitis (17%), extra-articular manifestations are rare. AS patients have abnormal lipid profiles and lower bone mineral density compared to healthy controls. HLA*B2704 is the predominant subtype in our Chinese patients whilst HLA*B2706 was found only in healthy controls. Intensive group physiotherapy is beneficial for patients with spondyloarthropathy.

Measuring quality of life in different cultures: translation of the Functional Living Index for Cancer (FLIC) into Chinese and Malay in Singapore

Goh CR, Lee KS, Tan TC, Wang TL, Tan CH, Wong J, et al.

Ann Acad Med Singap, 1996 May;25(3):323-34.
PMID: 8876896

Quality-of-life assessment has become an accepted method of evaluation in clinical medicine. The technique is based on a patient's self-assessment of physical, psychological, and social function, as well as the effects of distressing physical symptoms. The most important aspect of quality-of-life assessment is that it brings into focus a patient-centred view of health outcome, which is broader than the physiologic measures which predominate in Western medicine. Strategies for the development and use of assessment questionnaires have evolved over the past 15 years, and numerous questionnaires have been created. Most originate in Western societies, with English as the most common language of development. Adapting such questionnaires for use in other language and cultural settings is an imprecise practice. Language translation and equivalent cultural meaning must both be addressed. This paper reports on the language translation process and results for the Functional Living Index for Cancer (FLIC) as translated into Chinese and Malay in Singapore. We employed a step-wise process beginning with translation/back translation, followed by structured pilot field trials and population sampling. Taped versions of the questionnaire were devised to meet illiteracy problems in the sample population. Paired comparisons of the Chinese and Malay versions of individual questions with their English counterparts show good correlations and similar means most of the time. Factor analysis on a population sample of 246 (112 Chinese, 35 Malay and 98 English speaking) with cancers of minimal, extensive or palliative extent is convergent with that obtained on a North American population. However, a separate analysis of the Chinese questionnaires showed some differences in factor pattern. Specific language and cultural translation difficulties are discussed. Of note is the predicted significant decrease in total FLIC scores with extent of disease within each of the language preference populations, which provides some evidence for the validity for each language version in the Singapore culture(s). Thus, the FLIC translations into Malay and Chinese in Singapore can be considered for use in local trials, subject to ongoing evaluation.

Racial disparity in the prevalence of thyroid disorder during pregnancy

Sakinah SO, Khalid BA, Aishah AB

Ann Acad Med Singap, 1993 Jul;22(4):563-6.
PMID: 8257059

A study to determine the prevalence of goitre and abnormal thyroid status during pregnancy in Malaysian women was conducted. Two hundred and three women (Malay = 85, Chinese = 47 and Indian = 71) in the third trimester and with no known thyroid disease were studied. There was a marked racial disparity in the prevalence of goitre: Indian 61%, Malay 28% and Chinese 29% (p = 0.001). The serum thyrotropic hormone (TSH) was significantly higher in Indians (median: 1.36 uIU/ml) compared to Malays (1.14 uIU/ml, p = 0.009). The serum albumin was also significantly lower in Indians (mean +/- sd; 36.12 +/- 3.9 mmol/l) compared to Malays (39.3 +/- 4.8 mmol/l) or Chinese (39.1 +/- 5.2) (p < 0.001). Thyroid antibody was detected in 14.6% of these women with no significant racial difference in its prevalence. Three women were found to be thyrotoxic but none were hypothyroid. This study found a high prevalence of goitre among the pregnant Indian women, probably related to the protein malnutrition state. The high prevalence of positive thyroid antibody in our population indicates that a high percentage of women are at risk of developing postpartum thyroiditis.

Mortality analyses of the 1990 Singapore population: I. General life tables

Lun KC

Ann Acad Med Singap, 1995 May;24(3):382-92.
PMID: 7574420

General life tables for the 1990 Singapore resident population are given in this paper. Analyses were carried out separately for males and females for all ethnic groups as well as for Chinese, Malays and Indians. Average fractions of the last age interval lived were used to give a more precise derivation of the life table death rates from their corresponding age-specific death rates. The results show that in 1990, Singapore males had achieved a life expectancy at birth of 73.7 years while the females had attained a level of 78.6 years. These levels were comparable to those of many developed countries. Other interesting features include higher differentials in the life expectancies between sexes among the Chinese and the Indians taking over the Malays for second placing in terms of life expectancy at birth for both sexes. As a result, the Indians registered a 12% gain in life expectancy at birth for males for the decade 1980 to 1990, compared to only 7.1% for Chinese and 4.4% for Malays as well as nearly 10% for females compared to only 6.2% for Chinese and 6.3% for Malays. A subsequent paper will highlight the results of multiple-decrement life table analyses which will summarise the mortality of the 1990 Singapore resident population for various component causes of death rather than for all causes combined.

Racial differences in fetal morphometry in Singapore

Yeo GS, Chan WB, Lun KC, Lai FM

Ann Acad Med Singap, 1994 May;23(3):371-6.
PMID: 7944253

A systematic collection of fetal morphometric measurements was started seven years ago in 1987 with the prospective entry of data into personal computer-based stations in the Department of Obstetrics and Gynaecology, Singapore General Hospital. A cross-sectional study was done, comparing 2392 Chinese fetuses with 2117 Malay fetuses and 459 Indian fetuses from 18 to 40 weeks. The mean values of the head circumference (HC), abdominal circumference (AC) and femur length (FL) of the 3 ethnic groups were analysed. There were no statistical significant differences in the head circumference and abdominal circumference of Chinese, Malay and Indian fetuses in Singapore. The Chinese and Malay fetal femur length appeared similar but were apparently shorter than the Indian femur length. Nomograms of head circumference, abdominal circumference and femur length were constructed for application to fetuses of all 3 ethnic groups.

Prevalence and determinants of cervical cancer screening: a community-based study in Singapore

Seow A, Lee HP

Ann Acad Med Singap, 1994 May;23(3):342-7.
PMID: 7944247

A cross-sectional survey of 568 married women aged 21-65 years in the Pasir Panjang Constituency was conducted to determine the prevalence of cervical cancer screening in the community and the factors affecting acceptance of this screening test. Results show that 309 (54.4%) of the respondents had ever had a Pap smear. The women who reported having had a smear were more likely to be below 45 years of age (prevalence ratio 1.47, 95% confidence interval 1.15 to 1.88), Chinese and of a higher socioeconomic status (1.68, 1.33 to 2.12). They were also more likely to have married at a later age (1.68, 1.21 to 2.31) than women who had not had a smear. Age and socioeconomic status remained independent predictors on multivariate analysis. The findings suggest that an important task of public health practitioners is to increase the uptake of screening among older and socially disadvantaged women who are known to be at the highest risk of cervical cancer. In addition, strategies to encourage younger women to continue regular attendance at screening clinics beyond their childbearing years will be important for the future.

Obesity in preschool children: an intervention programme in primary health care in Singapore

Ray R, Lim LH, Ling SL

Ann Acad Med Singap, 1994 May;23(3):335-41.
PMID: 7944246

The Programme on Prevention and Management of Obesity in Preschool Children, aged three to six years, was implemented in 17 Primary Health Clinics in November 1991. The study sample comprised 1128 preschool children who qualified to enter the obesity register, using the defined criteria for obesity of 2 standard deviations above the normal weight for height and age. This group was divided into three categories, namely, mildly overweight (120% to below 140%), moderately overweight (140% to below 160%), and severely overweight (above 160%). The severely overweight category was referred to dietitians for follow-up management, while the other two categories were managed by the clinic staff through pre-planned nurse-conducted counselling sessions. In this paper, we analysed the first 1128 preschool children aged three to six years on the Programme with respect to their demographic characteristics; medical conditions; family history of obesity, diabetes, hypertension and ischaemic heart disease; number of siblings and parents' educational and occupational status. The Malay children showed significantly more severe grades of obesity compared to the Chinese and Indian children. A family history of obesity and hypertension among the three groups were significant (P < 0.001). After one year of follow-up with the intervention programme, the following were found: 40.4% (456) of the children improved in their obesity status and 20.2% (228) reached normal status. The severe, moderate and mild categories reduced from 6.3% to 5.9%, 29.3% to 23.2% and 64.4% to 50.7% respectively and was found to be statistically significant (P < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical observations on nail changes in psoriasis

Tham SN, Lim JJ, Tay SH, Chiew YF, Chua TN, Tan E, et al.

Ann Acad Med Singap, 1988 Oct;17(4):482-5.
PMID: 3265604

410 cases of psoriasis [282 males (68%) and 127 females (31%)] were interviewed and examined to study the nail changes. The prevalence of nail changes was 78.0% (males = females). Common changes were pitting (67.5%) and onycholysis (67.2%). Dystrophy of varying degrees occurred in 35.0%, subungual hyperkeratosis in 24.7%, discoloration in 18.4%, loss of nails in 2.8% and pustulation in 1.3%. Pitting and onycholysis was the most common combination (45.6%). Nail changes were significantly more common in patients who have moderate to severe psoriasis as compared with patients with mild psoriasis; in patients who have psoriasis for greater than 5 years as compared with patients who have psoriasis for less than 5 years; and in patients older than age 50 as compared with those aged less than 50. A definite correlation was found between the prevalence of nail changes and the presence of scalp and periungual psoriasis, and the presence of joint involvement.

Findings among 100 type 2 diabetics in a clinic in Penang, Malaysia, 1983-84

Merriman A, Ross I

Ann Acad Med Singap, 1985 Apr;14(2):277-85.
PMID: 4037686

A Specialist Clinic was commenced in August 1983, from the Medical School at Universiti Sains Malaysia, Penang, Malaysia to assess: 1) the present control and 2) the incidence of complications in a diabetic population already receiving primary health care at Penang General Hospital. The ethnic groups among the diabetics were Chinese (39%), Malays (26%) and Indian (35%). There was a greater percentage of Indians than would be expected from the ethnic distribution of the population of Penang. The results of the first 100 (43 males and 57 females) non-insulin dependent diabetic patients are reviewed. The mean age was 54 years, 41% had relatives with diabetes, and all were taking oral agents. The diet comprehension and compliance were poor. 65% of the group, 54% of males and 75% of females were obese. The mean blood glucose was 11 m.mols/l (fasting) and 12.8 m.mols/1 (2 hours post prandial). The complications seen in the 100 diabetics were: albuminurea 41, skin infection 37, cataracts 35, hypertension 32, peripheral sensory neuropathy 32, retinopathy 22, ischaemic heart disease 19, autonomic neuropathy 10, impaired renal function 4 (urea or creatinine elevated), foot ulcer 2 and gangrene 1. Urinalysis for glucose at the Clinic showed very little correlation with blood glucose at the same time. Nine out of 43 males admitted to impotence on questioning. Comparisons of findings in Penang were made with recent studies in Singapore and Hong Kong.

Diabetes mellitus in peninsular Malaysia: ethnic differences in prevalence and complications

Mustaffa BE

Ann Acad Med Singap, 1985 Apr;14(2):272-6.
PMID: 4037685

Estimated prevalence of diabetes mellitus in Malaysia was about 2%. Diabetes was most common in Indians especially males and least common in Chinese. There was a slight male preponderance seen in Malays and Indians. Positive family history was obtained in 14% of cases most commonly in Malays, almost 1/3 of whom had more than one family member with diabetes. Familial association was uncommon in Chinese. Over 50% of patients were overweight. Obesity was noted in nearly 70% of female Malays and Indians while the majority of Chinese were not overweight. More than 80% of patients were non insulin requiring. Youth onset diabetes was considered rare; those 10 years and below were estimated to be only 0.4% and below 20 years of age between 2%-4% of the diabetic population. Females were twice as common than males in this type of diabetes and familial association was greater. Malnutrition-related diabetes and pancreatic calcification were not well-documented but youth-onset non insulin requiring diabetics with mild symptoms but strong family history of diabetes were observed. More than half of hospital-based patients had evidence of complications, mainly amongst Malays and Indians. Hypertension was the most frequent associated disease followed by foot ulcers and ischaemic heart disease. Hypertension usually associated with chronic renal failure was most common amongst Malays while gangrenic ulcers and heart diseases were seen mainly in Indians. The major causes of death were chronic renal failure, myocardial infarction, ketoacidosis, stroke and septicaemia related to gangrene.(ABSTRACT TRUNCATED AT 250 WORDS)

Extremes of foetal birthweight for gestation in infants of diabetic mothers

Kek LP, Ng CS, Chng KP, Ratnam SS, Cheah JS, Yeo PB, et al.

Ann Acad Med Singap, 1985 Apr;14(2):303-6.
PMID: 4037690

100 patients were registered at the Diabetic Clinic in 1981, where they were managed by a team of physician, obstetrician and paediatrician, based on a preset protocol. Only 92 patients were eventually analysed. The study showed a 1.3% incidence of pregnancies complicated by diabetes mellitus. The mean birthweights of infants of both gestational and established diabetics were heavier than that of the general population by race and gestation. 25% of the 92 infants of diabetic mothers have birthweight exceeding the 90th centile of population. Further division of the 92 patients into the "true gestational" diabetics, as shown by an oral glucose tolerance test performed 6 weeks post-natally, also showed a 25% incidence of macrosomia. Late antenatal booking, delayed detection of abnormal glucose tolerance and treatment attributed to the high incidence of macrosomia. Only one infant had birthweight below the tenth centile. There were no perinatal mortality in the 92 patients studied. Macrosomia is a common complication in infants of diabetic mothers despite a physician-obstetrician joint-care system. Also, the risk of having macrosomia amongst gestational diabetics is high.
