Fulltext Medication noncompliance--a thriving problem

Aziz AM, Ibrahim MI

Med J Malaysia, 1999 Jun;54(2):192-9.
PMID: 10972029

A study was conducted among out-patients attending the Melaka Tengah Health Clinic to determine their compliance status towards antihypertensive, antidiabetic and antiasthmatic drugs. A total of 585 patients were enrolled in this study. Assessment of compliance was carried out using pill-counting and house-to-house interviews 14 days from the date of medication dispensed at the counter. The noncompliance rate among the 464 successfully interviewed patients was 56%. The mean noncompliance percentage was 78.0 +/- 43.1% (range: -10.0-314.3%). Among the four variables of compliance studied, race was not seen as a determinant of compliance. The older age group and those taking two or more drugs were statistically significant to be a noncomplier. Females were highly likely not to comply with drug therapy. Patients who conform to their refill dates were not really drug compliers. Forgetting to take their drugs and inability to read instructions on drug labels were the main reasons given. Underdosing was more common than overdosing, with an estimated cost of RM20,261.00 of unused medications per year.

Mucocutaneous manifestations of HIV infection: a retrospective analysis of 145 cases in a Chinese population in Malaysia

Jing W, Ismail R

Int J Dermatol, 1999 Jun;38(6):457-63.
PMID: 10397587

BACKGROUND: Mucocutaneous lesions directly related to human immunodeficiency virus (HIV) infection usually present as initial manifestations of immune deficiency. The most common mucocutaneous lesions are Kaposi's sarcoma, histoplasmosis, oro-esophageal candidiasis, oral hairy leukoplakia, and, in Asia, Penicillium marneffei infection. Non-HIV-related skin lesions, such as psoriasis, seborrheic dermatitis, and nodular prurigo, may be the initial presentation among HIV infected patients attending outpatient clinics.
METHODS: A retrospective analysis was performed on 145 HIV-positive Malaysians of Chinese descent from two centers at the University Hospital Kuala Lumpur (UHKL) and the General Hospital Kuala Lumpur (GHKL) from March 1997 to February 1998. Demographic data and clinical data were analyzed.
RESULTS: The analysis showed that 104 out of 145 patients had mucocutaneous disorders (71.7%). In the study, there were 100 men (96.2%) and four women (3.8%). The majority of patients were in the age group 20-50 years. The patients who presented with mucocutaneous disease also had low CD4+ T-lymphocyte counts and most had acquired immunodeficiency syndrome (AIDS) defining illness. The number of cases with generalized hyperpigmentation was very high in the group (35.9%), followed by nodular prurigo (29.7%) and xerosis (27.6%). Seborrheic dermatitis was seen in 20.7% of cases, with psoriasis in 8.3%. The most common infections were oral candidiasis (35.9%), tinea corporis and onychomycosis (9.7%), and herpes infection (5.5%); however, mucocutaneous manifestations of Kaposi's sarcoma were rare.
CONCLUSIONS: The results suggest that mucocutaneous findings are useful clinical predictors of HIV infection or signs of the presence of advanced HIV infection.

Associations of diabetes mellitus and ethnicity with mortality in a multiethnic Asian population: data from the 1992 Singapore National Health Survey

Ma S, Cutter J, Tan CE, Chew SK, Tai ES

Am J Epidemiol, 2003 Sep 15;158(6):543-52.
PMID: 12965880 DOI: 10.1093/aje/kwg199

Despite the high prevalence of diabetes mellitus, little is known about mortality associated with diabetes in Asia. Therefore, the authors followed 3,492 Chinese, Malay, and Asian Indian adults randomly selected from the general population in Singapore. Data on glucose tolerance, demographic characteristics, and other cardiovascular disease risk factors (lipid profile, blood pressure, smoking status, alcohol consumption, and obesity) were obtained in 1992. Vital status was determined as of December 31, 2001. There were 108 deaths over a period of 9 years. Impaired fasting glycemia or impaired glucose tolerance (IFG/IGT) (hazard ratio (HR)=1.39, 95% confidence interval (CI): 0.84, 2.31) and diabetes mellitus (HR=2.49, 95% CI: 1.58, 3.94) were associated with increased mortality after adjustment for age, gender, ethnic group, and educational level. Compared with Chinese with diabetes, Indians with diabetes experienced significantly greater mortality (HR=3.86, 95% CI: 1.76, 8.44) after adjustment for gender, age, educational level, smoking, hypertension, alcohol intake, and obesity. Undiagnosed diabetes and IFG/IGT were more common than known diabetes and also were associated with increased mortality. For reduction of mortality associated with IFG/IGT and diabetes, the authors recommend a screening program to detect undiagnosed diabetes and IFG/IGT along with aggressive treatment of diabetes after diagnosis.

Mental illness beliefs in Malaysia: ethnic and intergenerational comparisons

Edman JL, Koon TY

Int J Soc Psychiatry, 2000;46(2):101-9.
PMID: 10950358

Two groups of college students in Malaysia, ethnic Malay and ethnic Chinese, completed a mental illness attribution and help seeking questionnaire, and these responses were also compared with the responses of their mothers. As expected, ethnic Malays rated religious items, such as God and prayer, higher than the Chinese. However, both groups rated the social and psychological causes higher than religious, supernatural or physical causes. Contrary to our predictions, there were no intergenerational differences among either ethnic group. Medical pluralism was demonstrated, as a variety of apparently contradictory help seeking behaviors received quite high ratings including doctor/pharmacy, prayer, herbal medicine and traditional healers.

Distribution of hair on the dorsum of the phalanges of the hand in a Chinese population from Malaysia

Dharap AS, Lim BC, Ong LB

Anthropol Anz, 1996 Dec;54(4):311-6.
PMID: 9008788

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.

Corneal arcus and cardiovascular risk factors in Asians in Singapore

Hughes K, Lun KC, Sothy SP, Thai AC, Leong WP, Yeo PB

Int J Epidemiol, 1992 Jun;21(3):473-7.
PMID: 1634308

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.

The prevalence of symptoms in menopausal women in the Far East: Singapore segment

McCarthy T

Maturitas, 1994 Oct;19(3):199-204.
PMID: 7799826

Questionnaires (4000) on experience of menopausal symptoms in Singaporean women aged 40-55 were distributed by students. In total, 524 envelopes were returned (13.1%) and of these 420 were analyzed. Of these, 366 were classified as either pre-, peri- or postmenopausal on the basis of their menstrual patterns. Menopausal symptoms in this sample of Singaporean women were, in general, similar to those experienced in the West though the prevalence was low compared to European studies. No significant differences in individual symptoms were found between the 3 groups but, taken together, symptoms were significantly highest in the perimenopausal and lowest in the other menopausal groups. In the postmenopausal group 50% had been menopausal for at least 1 year at 50.5 years.

A study on the menopause in Malaysia

Ismael NN

Maturitas, 1994 Oct;19(3):205-9.
PMID: 7799827

In an attempt to gather data on the menopause in Malaysia, 400 women (13% Chinese, 70% Malays and 16% Indians), representing the three major ethnic groups in Malaysia, were interviewed. The majority (76%) of these women were still married and living with their husbands and 63% of them were working. Most of them (90%) had attained menarche by the age of 15 years and 50% of them had married before the age of 20. Their reproductive record was good, since 76% of them had 3 or more children who were still alive. The mean age at menopause in the Malaysian women studied was 50.7 years. Analysis of the climacteric symptoms reported showed significant differences in the vasomotor and nervosity indices in the perimenopausal and postmenopausal groups. Eighty percent (80%) of the women saw no need to consult a doctor about their climacteric symptoms. When they did, most of them (84%) received medication, but 43% of them did not comply with the prescribed treatment. Dyspareunia and urinary incontinence were evidently regarded as embarrassing complaints in all three groups, since around 80% of the women did not seek medical advice. This is not surprising in view of the fact that 89% of them rated their health as good.

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.

Cephalometric ideals in Chinese, Malay and Indian ethnic groups

Lew KK

Asian J Aesthet Dent, 1994;2(1):35-8.
PMID: 9063112

Cephalometric data from 105 female subjects (35 Chinese, 35 Malay and 35 Indian) with good occlusion and aesthetic pleasing facial profiles (determined by a trained clinician and endorsed by the lay public) were analysed using the Steiner analysis. Statistical analysis of the data showed that while the cephalometric ideals of the Chinese and the Malay ethnic groups were rather similar, cephalometric differences existed between the Chinese and Indians as well as the Malays and Indians. Compared to the Chinese and Malays, the Indians appeared to have less prognathic mandibles and maxillae, less protrusive and proclined upper and lower incisors and also less protrusive upper and lower lips. These differences demonstrate intrinsic ethnic differences and emphasize the need to treat patients of different ethnic groups using cephalometric norms which are peculiar to their own group.

Nasopharyngeal carcinoma in Malaysian Chinese: salted fish and other dietary exposures

Armstrong RW, Imrey PB, Lye MS, Armstrong MJ, Yu MC, Sani S

Int J Cancer, 1998 Jul 17;77(2):228-35.
PMID: 9650558 DOI: 10.1002/(SICI)1097-0215(19980717)77:2<228::AID-IJC

We interviewed 282 histologically confirmed cases of nasopharyngeal carcinoma (NPC) in Chinese residents of Selangor and the Federal Territory, Malaysia, and an equal number of Chinese age-, sex-, and length-of-residence-matched controls sampled from the general population. Consumption of 55 dietary items during childhood, and 5 years pre-diagnosis of NPC, was analyzed by univariate and multivariate methods. Four salted preserved foods (fish, leafy vegetables, egg and root), fresh pork/beef organ meats and beer and liquor consumption exhibited strong positive associations, and 4 vegetable/fruit combinations strong negative associations with NPC. Factor analysis and multivariable modeling using estimated factor scores strongly supported separate effects on NPC of vegetables/fruits, salted preserved foods, pork/beef organ meats and beer/liquor consumption. Multivariable modeling associated NPC most clearly with high consumption of salted fish, salted eggs, pork/beef liver and beer and low consumption of Chinese flowering cabbage, oranges/tangerines and shrimp. A strong residual association of social class with NPC remained after adjustment for diet, which is consistent with a substantial role for non-dietary environmental factors.

Lupus, 1997;6(1):27-31.
PMID: 9116715 DOI: 10.1177/096120339700600104

We analysed the causes of 67 deaths, over a 4 y period, in our oriental population with systemic lupus erythematosus (SLE). The median disease duration was 48 +/- 60.5 months (range 1-250 months). The mean age at diagnosis and death were 30 and 35.1 y respectively. SLE alone accounted for death in 30 patients (44.8%), infection in 27 (40.3%), pulmonary embolism in 5 (7.5%), malignancy in 4 (5.9%) and rheumatic heart disease in 1 (1.5%). The major organ involvement in those with active disease at death were SLE related thrombocytopenia (n = 23/44, 52.3%), nephritis (n = 21/44), 47.7%), cerebral lupus (n = 16/44, 36.4%), and pulmonary haemorrhage (n = 12/44, 27.3%). As in other series, SLE and infection were the principal causes of death in our population. During this 4 y period, there was no late death due to atherosclerosis.

Fulltext Circumstances surrounding accidental poisoning in children

Azizi BH, Zulkifli HI, Kassim MS

Med J Malaysia, 1994 Jun;49(2):132-7.
PMID: 8090091

Circumstances surrounding accidental ingestion of poisons were investigated in families of 70 hospitalised children. Indian children were more likely to be hospitalised for poisoning. Poor safety measures directly contributed to poisoning incidents. Poisons had not been stored safely and only in 12.9 per cent of families were the poisons allegedly kept in cupboards. Kerosene had been ingested from soft drink containers in 70 per cent of instances. Medications had been taken mainly from plastic envelopes (57.9%) or bottles (31.6%). Safety practices in the homes of cases and 140 controls were compared. As a whole parents of victims had poor safety practices when compared with parents of controls. Poisoning incidents were discovered by mothers in 75.0 per cent of the cases. Vomiting was induced by parents in 32.3 per cent of cases involving medications and non-volatile items, and in 41.6 per cent of kerosene ingestions. Before hospitalisation 59.4 per cent were brought to general practitioners and 22.7 per cent to government clinics. Mothers were the main attendants when children were brought for medical care. This study highlights the need for measures to prevent childhood poisoning and reduce its morbidity. Household products and medications should be made safer to children through improved packaging, prescribing instructions and education. Safety and first aid education may be directed towards parents, particularly mothers, through the media and health facilities.

Atopic eczema in a multiracial country (Malaysia)

Jaafar RB, Pettit JH

Clin Exp Dermatol, 1993 Nov;18(6):496-9.
PMID: 8252784

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.

Coronary artery disease in Asians

Rajadurai J, Arokiasamy J, Pasamanickam K, Shatar A, Mei Lin O

Aust N Z J Med, 1992 Aug;22(4):345-8.
PMID: 1445022

From available studies, there appears to be a racial preponderance of coronary artery disease (CAD) among Indians when compared to other ethnic groups. We found that this racial difference exists even in a young Asian population with premature atherosclerosis. In this small series, these racial differences could not be explained by the commonly known risk factors for coronary artery disease--smoking, hypertension, diabetes and hypercholesterolaemia, findings similar to those found in older patients elsewhere. Only fasting triglyceride levels were significantly higher among young Indians compared to non Indians (p less than 0.02) although the importance of this finding as a risk factor for CAD remains controversial. The majority of these young patients were treated medically and their one year survival was good.

Cross-cultural variations in dental knowledge among antenatal mothers

Esa R, Razak IA, Jalalludin RL

Odontostomatol Trop, 1992 Mar;15(1):19-23.
PMID: 1287607

This study evaluates the level of dental knowledge among 328 antenatal mothers from different ethnic groups and ascertains the importance of the various sources of dental information. The mothers were interviewed based on a structured questionnaire. Most mothers knew about the number of sets of teeth they possessed throughout their life. This was most evident among the Chinese and least among the Malays. Only 42.7% of the mothers interviewed were positive about the preservation of their teeth throughout life. This belief was highest among the Chinese followed by the Indians. However about 40% of the Chinese believed that tooth decay is hereditary. Generally the principal sources of dental information cited by most mothers were television or radio followed by dentists, school and family. This order of importance was similarly observed among the Malays and Chinese. However, among Indians, family members represent the second most important source of dental information. The implications of these findings are discussed.

Prevalence of visual disorders in Chinese schoolchildren

Chung KM, Mohidin N, Yeow PT, Tan LL, O'Leary D

Optom Vis Sci, 1996 Nov;73(11):695-700.
PMID: 8950751

We performed a vision screening of 1883 Chinese schoolchildren from 4 schools around Kuala Lumpur in June 1990. The group contained 1083-males and 800 females. Visual acuity, refractive error, oculomotor balance, and axial length were measured. The prevalence of myopia in Chinese schoolchildren was found to be 37% in the 6- to 12-year age group and 50% in the 13- to 18-year age group. Approximately 63% of the sample had unaided visual acuity of 6/6 or better and 24% had unaided acuity of 6/12 or worse. Six hundred twenty-five students (33%) failed the vision screening test and were referred for further examinations. The group which failed the vision screening test and had the highest rate of referral (46%) was the 11- to 12-year-old age group. The most common visual disorder was uncorrected myopia, accounting for 38% of the referrals (235 students). Only 26% of the sample were wearing a spectacle correction.
