    Hair distribution on the dorsum of phalanges of the hand was studied on 302 Chinese subjects (134 males and 168 females) randomly selected from the residents of Kota Bharu, Malaysia. Proximal phalangeal hair was seen on the dorsum of both hands in 99.3% of male subjects but in only 85.1% of female subjects. Chinese females showed a significantly lower (p < 0.05) incidence of proximal phalangeal hair on the hands than Chinese males. Comparison with other racial groups showed that Chinese females had significantly less (p < 0.05) hair on the proximal phalanges of the hands than Malay and African (Nigerian) females. The least common digital combination of proximal phalangeal hair in female subjects was the presence of proximal phalangeal hair only on the fourth digit (ring finger) and was noted in 0.6% of subjects. This has not been reported before. The frequency of middle phalangeal hair (MPH) distribution in Chinese falls between that in Malays and in Japanese which is probably explained by the fact that all these three racial groups originate from Asia. A study of digital combination of MPH in Chinese showed that the most common and the least common combinations in the Chinese differ considerably from those in other races. A total of 16 patterns of hair distribution was noted on the dorsum of the phalanges of the hands in Chinese subjects. Our study showed that though Chinese females had less digital hair on the hands than Chinese males, they showed a much larger variety of patterns of digital hair distribution than males.

    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.

    This article uses data from the United States, Jamaica, Malaysia, and Bangladesh to explore gender differences in adult health. The results show that women fare worse than men across a variety of self-reported health measures in all four countries studies. These health status disparities between men and women persist even after appropriate corrections are made for the impact of (a) differential mortality selection by gender and (b) sociodemographic factors. Data from Jamaica indicate that gender disparities in adult health arise early and persist throughout the life cycle, with different age profiles for different measures.

    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.

    This study was a cross-sectional random survey of the whole of Singapore, based on 2143 subjects (aged 18-69 years, response rate 60.3%). The presence of corneal arcus was determined by a doctor using the naked eye in good light. Cardiovascular risk factors were measured by standardized techniques. The prevalence rates overall of corneal arcus were: 18-29 years (males 0.5%, females 0.3%), 30-49 years (males 18.1%, females 13.3%) and 50-69 years (males 70.7%, females 55.3%). In the 30-49 age group, people with arcus had higher serum low density lipoprotein (LDL) cholesterol concentrations than people without arcus, the mean differences being, males 0.31 mmol/l (P = 0.040) and females 0.62 mmol/l (P less than 0.001) with an increased likelihood of having values greater than 5.5.mmol/l of males 1.8 (95% confidence interval (95% CI): 1.0-3.4) and females 2.6 (95% CI: 1.4-4.8). There were no significant differences for LDL-cholesterol in the 50-69 age group. Arcus was weakly associated with fasting plasma glucose in the 30-49 age group. Arcus was not associated with serum high density lipoprotein (HDL) cholesterol, serum fasting triglyceride, blood pressure and cigarette smoking. It is concluded that while corneal arcus is primarily an age-related change, its formation is accelerated by high serum LDL-cholesterol so that in people under 50 years it is a marker for the condition.

    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.

    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.

    A total of 14,342 patients with skin diseases who had attended either the National University of Malaysia skin clinic or a private dermatological office were analysed. Five hundred and thirty-four cases (3.7%) had atopic eczema, the prevalence being highest among the Malays (4.3%). The prevalence of atopic eczema among clinic attenders is lower in all three major Malaysian races when compared with studies from England.

    The maxillary casts of 320 Malaysian children were examined for the occurrence of the Carabelli trait on the maxillary first permanent molars. The total trait frequency was observed to be 52.2 per cent. Statistical analysis showed no sex dimorphism in the occurrence of the trait. Bilateral occurrence with a tendency towards concordance of expression between sides was also observed.

    We report a cross-sectional descriptive study of 90 new long-stay patients (NLS) (i.e. those who had been resident for six months to three years in Permai Mental Hospital, Johor) and studied from April to June, 1995. The age of this sample ranged from 18 to 85 years. Two subgroups were observed (i.e. younger NLS patients aged 18 to 34 years and older NLS patients aged 35 to 85 years). Among the younger NLS patients, the commonest diagnosis was schizophrenia (51.2%), followed by mental retardation with related problems (24.4%). Sixty-one percent of these younger patients had a history of serious violence or dangerous behaviour. Older NLS patients were likely to have a diagnosis of schizophrenia (79.6%), followed by mood disorder (6.1%) and dementia (4.1%). Forty seven percent of these older group had history of danger to others and 57.1% were at moderate or severe risk of non-deliberate self-harm. Focusing on the schizophrenic patients, all of them had some form of psychopathology, either positive, negative or general symptoms and about one-fourth were assessed to pose a risk for aggression.

    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.

    The lymphocyte subsets in the peripheral blood of healthy Malaysian adults (212 subjects, age 18-71 years) were analysed using a flow cytometer FACScan in an effort to establish a reference range for the lymphocyte subsets. The lymphocyte subsets studied were T cells (CD3), B cells (CD19), natural killer (NK) cells (CD3- CD16+/CD56+), helper/inducer cells (CD4), cytotoxic/suppressor cells (CD8) and the helper/suppressor ratio (CD4/CD8). The distributions of T cells, CD4 cells and CD8 cells were symmetric about their means while B cells, NK cells and CD4/CD8 ratio followed a skewed distribution. Differences in race were observed for T cells, NK cells, CD4 cells and CD4/CD8 ratio where the Indians were significantly different from the Malays and the Chinese (higher T cells, CD4 cells and CD4/CD8 ratio and lower NK cells). The B cells were significantly lower in the Chinese than the Malays and the Indians. Age differences were seen only in the Chinese where increased CD4 cells and CD4/CD8 ratio, and decreased CD8 cells were observed. A sex difference was observed only in the Chinese where the CD4/CD8 ratio was significantly higher in females than males.

    Circulating zinc concentrations were measured in 73 healthy adult males and females 19-52 years of age who were volunteers for eight different metabolic studies at the University of California, Berkeley. The interindividual variation in the eight studies varied from 5 to 20%; the global coefficient of variation for all studies was 12 +/- 7% (mean +/- SD). The analysis of a reference plasma sample on six different days showed a mean coefficient of variation of 3.8%. Thus, only a small portion of the intraindividual variation is due to day-to-day analytical differences. There was no relationship between circulating zinc concentrations and age, height, or body mass index. Nor were there any significant differences due to gender. Information regarding dietary zinc and protein intakes was available from three-day weighed food intake records from 44 of the subjects. Plasma zinc concentrations were unrelated to the intake of either zinc or protein in those subjects. The results of this study show that the impact of age, gender, body size and dietary zinc or protein on circulating zinc concentrations are too small to be detected in the presence of the analytical and endogenous factors that influence plasma/serum zinc concentrations. Also, within a population of healthy adults, circulating zinc concentrations may vary by as much as 15%.

    This is the first epidemiological survey of mental disorders among children in a Malaysian village. The WHO Research Questionnaire for Children (RQC) was used for initial screening followed by a semistructured interview, the Follow-up Interview for Children (FIC) at its second stage. Diagnosis was obtained by using Rutter's multi-axial classification. The prevalence rates obtained for the diagnostic categories were described in 3 age groups, in accordance with the age of attending school in Malaysia. Of 507 children screened aged 1-15, 6.1% were classified as having a mental disorder.

    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.

    A retrospective study of 95 patients with retinal vein occlusion was carried out to determine the clinical presentation and pattern of distribution in the local Malaysian population. There was no significant difference found in its distribution with regards to sex. In comparing branch retinal vein occlusion with central retinal vein occlusion, no significant differences were found in its racial distribution. Branch retinal vein occlusion occurred more commonly among the older patients whereas the converse is true for central retinal vein occlusion. Reduced vision represents the commonest mode of presentation. Hypertension, diabetes mellitus, hyperlipidaemia and haematological disorders are important associated systemic conditions.

    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.

    Fifty cases of septicaemic melioidosis were reviewed. There was a preponderance of disease among males (male:female ratio 3.2:1) and those aged over 30 years. The presenting clinical features were very varied and not pathognomonic, ranging from fever, cough and septicaemia to fulminant septicaemia and shock. Pulmonary involvement was recorded in 58% of the patients. Skin and soft tissue sepsis was seen in 24%, but many had signs and symptoms of multiorgan involvement. Associated underlying illness was identified in 76% of patients, diabetes mellitus being the commonest (38%), while 34% had more than one predisposing factor. The mortality of 65% in our series is a reflection of the less than satisfactory status of the diagnosis and therapy of septicaemic melioidosis. Only 24% of our patients received appropriate empirical antibiotic therapy. A high index of suspicion of melioidosis in endemic areas and the use of appropriate empirical antimicrobial therapy would be a step towards reducing the high mortality rate.
