Screening proteinuria and hematuria in Malaysian children

Zainal D, Baba A, Mustaffa BE

Southeast Asian J Trop Med Public Health, 1995 Dec;26(4):785-8.
PMID: 9139395

Screening for proteinuria and hematuria is important in the prevention of chronic renal disease. In Malaysia to date no such attempt has been made to establish the prevalence of proteinuria and hematuria. A total of 45,149 primary school children from three districts in Kelantan were screened for proteinuria and hematuria. They were 23,289 boys and 21,860 girls. The prevalence of abnormal urinary sediments after third screening was 0.17% ie 0.07% were in boys and 0.10% were in girls. The commonest abnormality was proteinuria (0.12%), followed by hematuria (0.03%) and combination of proteinuria and hematuria (0.02%). Hematuria was more commonly seen in girls compared to boys while proteinuria was seen in almost equal proportion in boys and girls. Despite screening large number of children the prevalence of asymptomatic proteinuria and hematuria was far lower than in an earlier reported study. Furthermore the majority had mild abnormalities.

The pattern of chronic renal failure in Kelantan, northeastern state of Malaysia

Zainal D, Monniaty M, Nazmi N

Southeast Asian J Trop Med Public Health, 1995 Dec;26(4):781-4.
PMID: 9139394

The pattern and outcome of patients with chronic renal failure (CRF) in Kelantan, the northeastern state of Malaysia was determined. A total of 60 patients with CRF managed at the Hospital Universiti Sains Malaysia between January 1991 and June 1993 were reviewed retrospectively. The prevalence of CRF was 24.8 patients per year. The ratio of male to female patients was 1.5 : 1.0. Their mean age at presentation was 51.4 +/- 13.7 years. The cause of CRF in majority of our patients was unknown. Their mean blood urea and serum creatinine were 38.9 +/- 9.8 mmol/l and 1,154.9 +/- 458.7 mumol/l respectively. Sixty-five percent of our patients were already in end-stage renal failure (ESRF) at the time of presentation and only 53.8% of them could afford a definitive renal replacement therapy. Their mortality rate was 21.7% and majority of the death occurred in patients who were not receiving definitive renal replacement therapy. This debilitating course will continue unless the cost of renal replacement therapy is subsidised or a renal transplantation program is activated. Hence public education to encourage organ donation in this part of Malysia is necessary.

Fulltext Upper eyelid and eyebrow dimensions in Malays

Dharap AS, Reddy SC

Med J Malaysia, 1995 Dec;50(4):377-81.
PMID: 8668060

The upper eyelid crease height pretarsal skin and eyebrow height were studied in 305 Malay subjects (146 males and 159 females) varying in age from 2-80 years, who were randomly selected from the residents of Kota Bharu, Kelantan. In females, from the age of 11 years the mean pretarsal skin height increased progressively with age. In males, however, it decreased with age up to 60 years. In both sexes, subjects more than 60 years old showed highest values for pretarsal skin height. The mean eyelid crease height increased progressively with age from 11 years onwards in males but not in females. The mean eyebrow height increased with age in females but not in males. Eyebrow and eyelid measurements seem to show a definite racial variation. Besides establishing normal values for eyelid and eyebrow measurements in Malays, our findings indicate that age and sex should be taken into consideration to achieve satisfactory results in cosmetic eyelid surgery in Malays.

Fulltext A community based study on the prevalence and factors affecting smoking in Kampong Jenderam Hilir, Sepang, Selangor

Rampal L, Narasimman S

Med J Malaysia, 2003 Mar;58(1):54-61.
PMID: 14556326 MyJurnal

Objectives: i) To determine the prevalence of smoking among the community aged 15 and above in Kg. Jenderam Hilir in Sepang District, Selangor state. ii) To determine the relationship between smoking and age, sex, household income and education. iii) To determine the parental and peer influence on smoking in Kg Jenderam Hilir.
Materials and Methods: A study was conducted to Kg Jenderam Hilir, Sepang. All residents aged 15 years and above from all the 381 households of Kg Jenderam Hilir were included in this study. A standardized pre-tested structured questionnaire was used in this study.
Results: Out of 894 respondents interviewed 69% were males compared to 3.9% of the females (overall 33.6%) reported to have smoked at least once in his/her lifetime. The difference was statistically significant. The mean duration of smoking was 17.7 years. The age at which smoking was first attempted ranged from 4 years to 51 years with a mean of 18.7 years. The mean initiation age for the males was significantly lower as compared to the mean initiation age for the females. The prevalence of current smokers was significantly higher amongst males (52.8%) as compared to the females (1.4%). The prevalence of smoking among current smokers increased with age (p<0.01). there was no significant difference in the prevalence of smoking by household income and educational level. The mean number of cigarettes smoked by current smokers per day was 14.9 cigarettes and ranged from 1 to 60 cigarettes. The mean number of cigarettes smoked by the males was significantly higher than the females (p<0.05). the mean duration of smoking among current smokers was 20 years. There was a significant difference in the level of addiction to smoking and the duration of smoking (p<0.05). sixty five percent of the current smokers reported to have tried to quit smoking while 26% of ever smokers had reported to quit smoking and remained non-smokers. The quit ratio was calculated to be 26.0%. the quit ratio was 52.6% among those with college or university education. There was a significant difference in the quit ratio by education level (p<0.01). There was no significant difference in smokers whose parents were smokers as compared to non-smokers whose parents were smokers. However, there was a significant association between smoking and peer influence (p<0.01).

Fulltext Glomerulonephritis in Kelantan, Malaysia: a review of the histological pattern

Zainal D, Riduan A, Ismail AM, Norhayati O

Southeast Asian J Trop Med Public Health, 1995 Mar;26(1):149-53.
PMID: 8525403

Renal biopsy is essential in the management of renal parenchymal diseases. Thus far there is no publish report on the pattern of glomerulonephritis in Kelantan. We decided to establish the pattern of glomerulonephritis in Kelantan and use this information as our reference in future studies. Records of patients who had proven glomerulonephritis histologically were analysed. Their biological data, clinical presentation, etiology and clinicopathological pattern were studied. Where appropriate mean and standard deviation were calculated. A total of 74 biopsies were performed during the study period (between January 1991 and December 1993), out of which 72 biopsies (97.3%) were considered suitable for analysis. The male to female ratio was 1:1.1. Mean age at presentation was 27.6 +/- 12.2 years. Nephrotic syndrome was the commonest clinical presentation (65.3%). The main underlying cause was systemic lupus erythematosus (50%) followed by primary glomerulonephritis. Histologically, IgA nephropathy and minimal change disease were the main patterns among patients with primary glomerulonephritis while diffuse proliferative glomerulonephritis was the commonest pattern among patients with lupus nephritis. Hence the pattern of glomerulonephritis is similar to other reported series. The procedure is considered safe and has a high success rate.

Fulltext Febrile seizures in Malaysian children: epidemiology and clinical features

Deng CT, Zulkifli HI, Azizi BH

Med J Malaysia, 1994 Dec;49(4):341-7.
PMID: 7674969

A child with a febrile seizure is a common cause of admission in a general paediatric ward in Malaysia. We set out to look prospectively into the clinical and epidemiological features of these children. A total of 117 children were admitted into the study. The ratio of boys to girls were 1.5:1.0. The racial breakdown was 62.4% Malays, 26.5% Indians, 8.5% Chinese and 2.6% others. The first febrile seizure occurred before the age of three years in 92.9% of our patients. The highest number of febrile seizures was in the six to 12 months age group. The average length of seizure was 9.5 minutes and the majority were non-recurrent. Febrile seizures with complex features occurred in 33.3% of the children. Upper respiratory tract infection was the most common cause of fever in our patients. There was a family history of seizures (febrile or afebrile) in 26.5% of patients.

Iodine content in urine samples among Malays and aborigines

Ali O, Muda K, Khalid B

Acta Med Okayama, 1994 Dec;48(6):289-92.
PMID: 7709757

A study was conducted to compare the urinary iodine concentrations in populations from Pahang, Central Malaysia, with those in the capital city Kuala Lumpur, and to compare those of Malays from villages at Batu Talam, Batu Malim, FELDA Sungai Koyan and Hulu Sungai with neighboring aboriginal settlements at Lanai and Buntu. Two hundred and forty urine samples were collected randomly among the population (male 1 1 1 and female 129). The urinary iodine concentrations, measured by the ashing method, among Malays were as follows: Batu Talam 1.1-7.6 micrograms/dl, Batu Malim 1.4-6.6 micrograms/dl, FELDA Sungai Koyan 0.5-6.9 micrograms/dl and Hulu Sungai 0.6-9.9 micrograms/dl. Among aborigines, the urinary iodine levels were 0.1-2.9 micrograms/dl in Lanai and 1.7-6.5 micrograms/dl in Buntu. There was a significant difference in the levels of urinary iodine with regard to gender, but not regarding age. The aborigines had significantly lower iodine levels than Malays (P < 0.001). This difference was also significant with regard to location. The urinary iodine content in Kuala Lumpur was the highest and that in the aboriginal Lanai village was the lowest. Thus, the study showed that the levels of iodine in the urine were influenced by ethnicity and geographic location.

Abdul-Kadir R

J Nihon Univ Sch Dent, 1994 Mar;36(1):34-9.
PMID: 8207502

A cross-sectional exploratory survey was conducted in six West Malaysian schools involving 762 fifteen- to eighteen-year-old secondary school students. Periodontal health status was assessed using the Community Periodontal Index of Treatment Needs (CPITN), utilizing six index teeth to represent the six sextants of the mouth. The results indicated that 66.8% of the students examined had healthy gingiva (Score 0), 2.6% had bleeding of the gingiva on gentle probing, while 30.6% had calculus on their teeth. In terms of treatment needs, 35.0% of those examined needed oral hygiene education, 34.4%, on the other hand, required scaling. No student was found to require complex treatment. Sex-specific comparison revealed a slightly higher prevalence of calculus formation in male students. In terms of race, the Malays had a higher prevalence of calculus formation than either Chinese or Indians.

Glucose-6-phosphate dehydrogenase enzyme activity of normal term Malaysian neonates of different ethnic origins

Boo NY, Ainoon BO, Ooi LH, Cheong SK, Haliza BM

J Paediatr Child Health, 1994 Jun;30(3):273-4.
PMID: 8074916

The cord blood glucose-6-phosphate dehydrogenase (G6PD) enzyme activity of 262 normal term Malaysian neonates (92 Malays, 96 Chinese and 74 Indians) was quantitatively determined by the World Health Organisation method. Analysis of variance for the levels of G6PD enzyme activity by ethnic origin and sex showed that there was a significant difference between mean levels of enzyme activity in the three ethnic groups (P = 0.03) but no difference between the sexes (P = 0.36). Multiple range analysis showed that Malays had significantly higher mean levels of G6PD enzyme activity than those of Chinese (P = 0.01). There was no significant difference between the mean levels of G6PD enzyme activity of Chinese and Indians (P = 0.52), nor was there any difference between those of Malays and Indians (P = 0.08). The difference in levels of G6PD enzyme activity among the different ethnic groups could be due to the existence of different G6PD variants.

The expression of rheumatoid arthritis in Malaysian and British patients: a comparative study

Veerapen K, Mangat G, Watt I, Dieppe P

Br J Rheumatol, 1993 Jul;32(7):541-5.
PMID: 8339122

Seventy consecutive patients with definite or classical RA attending a University Hospital Rheumatology Clinic in Malaysia, were compared with an age, sex, disease duration matched group of RA patients seen in a British University Hospital. There were no differences in measures of disease activity, overall functional status or serological status in the two groups. However significant differences were seen in both the articular and extra-articular manifestations of the disease in the two countries. British patients had more severe disease in the feet, and a higher prevalence of nodules, vasculitis and pulmonary fibrosis. The Malaysian population had fewer erosions, more frequent involvement of the wrists and cervical spine, and a much higher incidence of secondary sicca syndrome. Radiographic changes were generally milder in Malaysian patients. Possible reasons for these differences in the expression of RA in the two countries are discussed.

Fulltext Epidemiology of aplastic anaemia in the state of Sabah, Malaysia

Yong ASM, Goh AS, Rahman M, Menon J, Purushothaman V

Med J Malaysia, 1998 Mar;53(1):59-62.
PMID: 10968139

Aplastic anaemia is a rare disease which is more prevalent in the Far East. In Malaysia, it appears to be unusually common in the state of Sabah. A retrospective analysis of all cases of aplastic anaemia diagnosed between January 1993 and March 1996 was undertaken. The criteria of the International Aplastic Anaemia and Agranulocytosis Study (IAAAS) was used. In this 39 month period, 31 cases were confirmed by marrow trephine biopsy to be aplastic anaemia. The male-to-female ratio was 3.4. Median age of diagnosis was 23 years. There were 24 patients (77%) who were from the Kadazan-Dusun ethnic group, which forms 18% of the population of Sabah. The incidence of aplastic anaemia in Sabah appears to be higher than that reported elsewhere in the Far East, at 4.8 per million population per year. Peak incidence is in the elderly group at 8.6 per million followed by a second peak in young people aged 15 to 24 (7.9 per million). The aplastic anaemia to total acute leukaemia ratio is 0.37. The marked male preponderance and apparent susceptibility of the Kadazan-Dusun people are also notable. A further prospective study to address the true incidence of aplastic anaemia and possible aetiologic factors accounting for these observations is necessary.

Fulltext Epidemiology of head injury in Malaysian children: a hospital-based study

Rohana J, Ong LC, Abu Hassan AA

Med J Malaysia, 1998 Sep;53(3):217-22.
PMID: 10968156

A prospective observational study was carried out at the Emergency Department, Hospital Kuala Lumpur to determine the proportion of accidental head injury among children and the circumstances of injury. The study was carried out from November 1993 to January 1994 on all children below 14 years who presented to the Emergency Department with accidental head injury. Accidental head injury made up (4.75%) of all cases seen at the Casualty Department. The ratio of boys to girls was 2:1. The mean age of head injured children was 5.2 (S.D. 3.63) years. The leading cause of head injury was fall (63%) followed by road traffic accidents (RTA) in (30.7%) while the rest were due to 'impact' (injury caused by flying object or missiles) injuries. More than half (54.4%) of those injured in RTA were pedestrians. Pedestrian injury was particularly important in the 5-< 14 years age group, where adult supervision was lacking in two thirds of the children. None of the patients who were involved in vehicle-related injuries had used a suitable protective or restraining device. All three patients who died were from this group. This study emphasises the need for stricter enforcement of laws related to the use of protective devices and measures to decrease child pedestrian injury. The issues of lack of adult supervision, both in and outside the home need to be addressed.

Fulltext Peak expiratory flow rate in elderly Malaysians

Srinivas P, Chia YC, Poi PJH, Ebrahim S

Med J Malaysia, 1999 Mar;54(1):11-21.
PMID: 10971999

An epidemiological survey was conducted among 1,414 healthy ambulatory elderly persons aged 55 years and above in the Kuala Langat district, Selangor. The relationship between peak expiratory flow rate (PEFR), demographic variables, socioeconomic status, smoking, alcohol use and respiratory symptoms were examined. The peak expiratory flow declined with age and were lower in women of all ages. Smoking had a modest effect on PEFR in men but not on PEFR in women. The combination of respiratory symptoms of cough, phlegm and wheeze were related to lower PEFR values. Prediction equations are presented derived from the population sample which may be of assistance in assessing observed to expected ratios among elderly people in Malaysia.

Wong TY, Foster PJ, Seah SK, Chew PT

Br J Ophthalmol, 2000 Sep;84(9):990-2.
PMID: 10966951

AIM: To estimate the rates of hospital admissions for primary angle closure glaucoma (PACG) in Chinese, Malays, and Indians in Singapore
METHODS: A population-wide hospital discharge database in Singapore was used to identify all hospital admissions with a primary discharge diagnosis of PACG (International Classification of Disease-CM code: 365.2). The Singapore census was used for denominator data.
RESULTS: Between 1993 and 1997 there were 894 hospital admissions for PACG. The mean annual rate of PACG admissions was 11.1 per 100 000 (95% confidence interval (CI), 10.4, 11.8) among people aged 30 years and over. The annual rate was highest for Chinese (age and sex adjusted rate: 12.2 per 100 000), which was twice that of Malays (6.0 per 100 000) and Indians (6.3 per 100 000). Females had two times higher rates than males in all three races (age adjusted relative risk: 2.0, 95% CI: 1.7, 2.3).
CONCLUSION: Malay and Indian people had identical rates of hospital admissions for PACG, which were only half the rates compared with Chinese.

Poverty and mortality among the elderly: measurement of performance in 33 countries 1960-92

Wang J, Jamison DT, Bos E, Vu MT

Trop Med Int Health, 1997 Oct;2(10):1001-10.
PMID: 9357491

This paper analyses the effect of income and education on life expectancy and mortality rates among the elderly in 33 countries for the period 1960-92 and assesses how that relationship has changed over time as a result of technical progress. Our outcome variables are life expectancy at age 60 and the probability of dying between age 60 and age 80 for both males and females. The data are from vital-registration based life tables published by national statistical offices for several years during this period. We estimate regressions with determinants that include GDP per capita (adjusted for purchasing power), education and time (as a proxy for technical progress). As the available measure of education failed to account for variation in life expectancy or mortality at age 60, our reported analyses focus on a simplified model with only income and time as predictors. The results indicate that, controlling for income, mortality rates among the elderly have declined considerably over the past three decades. We also find that poverty (as measured by low average income levels) explains some of the variation in both life expectancy at age 60 and mortality rates among the elderly across the countries in the sample. The explained amount of variation is more substantial for females than for males. While poverty does adversely affect mortality rates among the elderly (and the strength of this effect is estimated to be increasing over time), technical progress appears far more important in the period following 1960. Predicted female life expectancy (at age 60) in 1960 at the mean income level in 1960 was, for example 18.8 years; income growth to 1992 increased this by an estimated 0.7 years, whereas technical progress increased it by 2.0 years. We then use the estimated regression results to compare country performance on life expectancy of the elderly, controlling for levels of poverty (or income), and to assess how performance has varied over time. High performing countries, on female life expectancy at age 60, for the period around 1990, included Chile (1.0 years longer life expectancy), China (1.7 years longer), France (2.0 years longer), Japan (1.9 years longer), and Switzerland (1.3 years longer). Poorly performing countries included Denmark (1.1 years shorter life expectancy than predicted from income), Hungary (1.4 years shorter), Iceland (1.2 years shorter), Malaysia (1.6 years shorter), and Trinidad and Tobago (3.9 years shorter). Chile and Switzerland registered major improvements in relative performance over this period; Norway, Taiwan and the USA, in contrast showed major declines in performance between 1980 and the early 1990s.

Enzyme activity of glucose-6-phosphate dehydrogenase-deficient Malaysian neonates during the first 10 days of life

Boo NY, Ainoon O, Arif ZA, Cheong SK, Haliza MS

J Paediatr Child Health, 1995 Feb;31(1):44-6.
PMID: 7748690

OBJECTIVE: The objective of this study was to determine the degree of severity of enzyme deficiency in glucose-6-phosphate dehydrogenase (G6PD)-deficient Malaysian neonates as part of an effort to identify risk factors associated with severe hyperbilirubinaemia in G6PD-deficient infants.
METHODOLOGY: During this study, enzyme activity was measured in 53/59 (89.8%) hospital-diagnosed G6PD-deficient neonates (34 Malays, 12 Chinese, and seven other ethnic groups) born consecutively in the Kuala Lumpur Maternity Hospital. All neonates, except one, were males.
RESULTS: The mean level of enzyme activity of the 52 males G6PD-deficient neonates (0.47 iu/g Hb, 95% confidence intervals: 0.37, 0.57) was less than 10% of that of normal Malaysian male neonates. The enzyme activity of the only female G6PD-deficient infant, at 1.11 iu/g Hb, was 12.5% of the mean G6PD enzyme activity of normal females.
CONCLUSION: Our results showed that G6PD deficiency in Malaysian neonates predominantly affects males and is usually severe.

Absenteeism in the workforce, Klang Valley, Malaysia--preliminary report

Indran SK, Gopal RK, Omar A

Asia Pac J Public Health, 1995;8(2):109-13.
PMID: 9037807 DOI: 10.1177/101053959500800209

The aim of this study was to determine the prevalence of sickness absenteeism among the three types of agencies, government, semi-government (boards) and private (public) companies. The methodology involved eliciting retrospective data on medical leave over the year 1990 by requesting the agencies to fill up a questionnaire (Appendix I), and calculating the indices of absenteeism from this data. The results show that the private agencies scored higher for all the indices but only the "lost time" percentage was significantly increased. Females also had significantly higher severity of sickness absenteeism rates in all the agencies. Overtime work was associated with higher absenteeism indices, markedly noted in the private agencies. In conclusion, agencies showed work out their own indices of absenteeism so that it could be compared with national rates.

PMID: 7565180

Hospital records of children admitted to the department of Paediatrics, University Hospital, Kuala Lumpur, from January 1981 to December 1990, who were diagnosed to have acute rheumatic fever (ARF) were studied. 134 children satisfied the Jones' modified criteria, thus giving a hospital incidence of 21.2/100,000 paediatric admission per year, of which incidence of first attack was 15.8/100,000 per year and recurrent attack was 5.38/100,000 per year. The M:F ratio is 1.39:1. Majority of cases occur in the 6-11 years age group with 6 cases encountered below the age of 5. The Indians had a higher relative risk to develop both the first acute attack as well as recurrences with a relative risk of 2.4 and 4.10 respectively as compared to the Malays. Majority of the patients, irrespective of the ethnic group, came from families with low income.

Fulltext Enterobius vermicularis infection among children aged 1-8 years in a rural area in Malaysia

Norhayati M, Hayati MI, Oothuman P, Azizi O, Fatmah MS, Ismail G, et al.

Southeast Asian J Trop Med Public Health, 1994 Sep;25(3):494-7.
PMID: 7777914

The infection rate and relationship of enterobiasis with socio-economic status were determined in children aged 1-8 years, living in a rural area in Malaysia. Of the 178 subjects 40.4% were infected with Enterobius vermicularis. The distribution of enterobiasis among these children were analyzed in relation to age groups and sex. The rate of infection was significantly higher in older children (5-7 years). The association of enterobiasis with other factors studied such as number of persons per house, household income per months and mother's employment status were not significant. The sensitivity of three successive days anal swabs compared to a single swab was found to be statistically significant.

Fulltext Penang cancer cases reported to the National Cancer Registry of Malaysia, 1987-1990: an epidemiological analysis

Chan CK, Singh J, Rasid BK, Devaraj T

Med J Malaysia, 1994 Jun;49(2):122-31.
PMID: 8090090

2,124 cases of cancer diagnosed and/or treated in Penang between 1987-1990 were reported to the National Cancer Registry of Malaysia by hospitals in Penang. 1,762 met the criteria for Penang incident cases first diagnosed between 1987-1990, and were the subjects on which all subsequent analyses were based. 85 per cent of case notifications were from Mount Miriam Hospital. Among males, all-site cancer incidence rates (age-standardised) were highest among Chinese, and lowest among Malays. Among females, the Indian female incidence rate was highest, higher than that of any other ethnic-gender sub-group. Site-specific cancer rates varied according to ethnicity and gender, but overall the four most frequent cancers reported from Penang were breast, lung, cervix and nasopharynx cancers. It needs to be emphasised that all these results are highly tentative since they are based on notified cancer occurrences and hence are very uncertain proxies for true cancer incidence. Based on incidence rates from the Singapore Cancer Registry (1978-1982), the expected number of incident cases in 1989 for Penang (Malays, Chinese and Indians combined) was 1,561. The number notified to the National Cancer Registry was 496. This underlines the tentative nature of this analysis of the returns for 1987-1990 from Penang.
