Fulltext Review of toxoplasmosis in Malaysia

Yahaya N

Southeast Asian J. Trop. Med. Public Health, 1991 Dec;22 Suppl:102-6.
PMID: 1822863

Various studies on toxoplasmosis in Malaysia have shown that specific antibodies to Toxoplasma gondii are common among Malaysians. Among the ethnic groups, the Malays have the highest prevalence rate followed by Indians, Orang Aslis (aborigines) and Chinese. Antibody is acquired early in life and increases with age. There is no significant difference in the prevalence rate between males and females. The disease is apparently more prevalent among rural dwellers and those in the lower socioeconomic group. It appears that the prevalence rate is also influenced by environmental conditions, occupation, diet and cultural habits. Studies with animals have shown the presence of antibody to T. gondii, but this does not seem to be the source of infection since Malaysians normally cook their meat well.

Development of immunity to Epstein-Barr virus in Malaysian children

Yadav MS, Malliga N, Ablashi DV

Microbiologica, 1987 Jan;10(1):29-35.
PMID: 3033449

The pattern of seroconversion to Epstein-Barr virus (EBV) was determined in 98 Malaysian children aged 2 weeks to 12 years. Maternal IgG antibodies to EBV viral capsid antigen, ranging between 1:10 to 1:160 titer, were found in 70.6 percent of infants less than three months old, and dropped to 26 percent by seven to nine months. Primary infection, as denoted by emergence of EBV-IgM antibody, occurred at 4 to 6 months, and by eight years all children were seropositive. Maternal antibody titers to EBV nuclear antigen were detected in 52.9 percent of infants less than 3 months old, declined to undetectable levels by 4 to 12 months, and then increased to 40 percent by the age of 12 years. The IgA antibody to viral capsid antigen was absent in all but one infant aged one year; the child also had IgG anti-early antigen, The IgG antibody to EBV early antigen were present in 17.7 percent of the infants aged 3 months or less. This seroconversion to EBV in early life explains the absence of infectious mononucleosis in the Malaysian population. The data suggest that a subunit vaccine to protect against EBV-associated diseases, most notably nasopharyngeal carcinoma, commonly observed in Malaysians would have to be administered to infants 6-12 months of age.

Malaria antibody levels in patients with nasopharyngeal carcinoma

Yadav M, Prasad U

Southeast Asian J. Trop. Med. Public Health, 1984 Jun;15(2):234-7.
PMID: 6095462

The antibody titres to P. falciparum and Epstein-Barr Virus-associated antigens were assayed in 22 patients with NPC and 43 controls. All, but one patient had antimalarial titres; 14 had titres greater than 80 and 4 patients greater than 640. Compared to controls the mean anti-malarial titre for most age groups were higher in the patients. Those patients with high anti-malarial titres also had high IgA anti-VCA titre, an antibody which has been demonstrated to be diagnostic for NPC. The peak anti-VCA (IgG) and anti-EA (IgG) antibody titres were associated with anti-falciparum titres of 320-640 and 80-160, respectively. The results are discussed in relation to the possible association between malarial infection and etiology of NPC.

Fulltext The 1978 cholera outbreak in Krian district

Yadav H

Med J Malaysia, 1981 Sep;36(3):129-35.
PMID: 7329369

The findings of a cholera epidemic in Krian district is reported. There were 77 cases and 92 carriers in the epidemic. Although the three main ethnic groups of Malays, Chinese and Indians were involved in the epidemic, the Malays constituted majority of the cases and carriers. The overall infection rate and case attack rate was higher among the younger population. The case: carrier ratio was also higher among the younger population especially among Indians. Various reasons and probable causes of the epidemic have been described briefly.

The expression of cytokine genes in the peritoneal macrophages and splenic CD4- and CD8-positive lymphocytes of the nonobese diabetic mice

Yaacob NS, Kaderi MA, Norazmi MN

J Clin Immunol, 2004 Mar;24(2):177-84.
PMID: 15024185 DOI: 10.1023/B:JOCI.0000019783.61674.1d

Type 1 diabetes is an autoimmune disease that results from the destruction of the insulin-producing pancreatic beta islet cells, probably via the influence of cytokines. However, direct correlation between the expression of selected cytokines by various immune cells at different time points during the progression of the disease has not yet been clearly demonstrated. In this study, we showed that the mRNA expression of the pro-inflammatory cytokines, TNF-alpha, IL-1 beta, IL-6, and GM-CSF, were increased while the anti-inflammatory cytokine, TGF-beta, decreased in the peritoneal macrophages of nonobese diabetic (NOD) mice. IL-6 expression however decreased when the mice became diabetic. Surprisingly the expression of IFN-gamma and IL-2 by splenic CD4+ cells were lower in 5-week-old NOD mice as compared to the nonobese diabetic resistant (NOR) control mice, but their expression was higher in older NOD mice. The expression of IL-4 and IL-10 decreased in splenic CD4-positive lymphocytes. Splenic CD8-positive lymphocytes expressed increased levels of IFN-gamma and IL-10 but the latter decreased sharply when diabetes occurred. The relevance of these findings to the pathogenesis of type 1 diabetes is discussed.

Health seeking behaviour of menopausal women with urinary incontinence in North east Malaysia

Yaacob LH, Abdul Mokti S, Muhammad J

J Women Aging, 2019 04 09;32(5):537-545.
PMID: 30967095 DOI: 10.1080/08952841.2019.1593799

Urinary incontinence (UI) is common in women in postmenopausal age, but many women delay seeking treatment. The objective of this study is to determine health-seeking behavior of postmenopausal women with UI and its associated factors. This is a cross-sectional study involving 348 postmenopausal women from the outpatient clinic using personal data forms and a validated UI questionnaire. A total of 348 menopausal women were involved in the study. Only 13.17% of patients with UI sought treatment. Factors associated with seeking treatment were age of menopause and severity of UI. More health education needs to be done among these patients.

Fulltext Association of rhinitis in adult asthmatic

Yaacob I, Elango S

Asian Pac J Allergy Immunol, 1991 Jun;9(1):39-43.
PMID: 1776978

In a study of 124 adult patients with bronchial asthma, 65% of them had associated rhinitis. In the asthmatics who had associated rhinitis, both diseases usually started within two years of one another but either disease might develop first. In 21% of the patients, asthmatic attacks were preceded or precipitated by rhinitis symptoms. In the patients who had asthma alone or those associated with rhinitis, no significant difference were found in terms of age and sex distribution, age of onset, and a positive family history of asthma, rhinitis or allergic diseases. Response to skin prick test using six different types of allergens also showed no difference in the two groups of patients. Sensitivity to house dust was common among both groups of patients as well as in the normal controls suggesting a common occurrence of house dust mite in our community and making the skin prick test using this allergen unsuitable as a test for atopy in our population.

Fulltext The immediate outcome of ventilation for pulmonary diseases

Yaacob I, Mustafa M

Singapore Med J, 1994 Oct;35(5):512-4.
PMID: 7701374

Fifty-eight patients were ventilated for acute respiratory failure complicating respiratory diseases between 1985 to 1990. There were 19 cases of chronic obstructive airway disease (COAD), 17 cases of asthma, 16 cases of pneumonia and 6 cases with other diagnoses. Overall, 40% of patients survived and were discharged from the ward. Patients with pneumonia had the lowest survival rate (25%) whilst the survival rates for asthma and COAD were 47% and 42% respectively. Increasing age had an inverse relationship to survival rate (r = 0.96, p < 0.05) but the duration of ventilation did not correlate with survival. Patients who were electively ventilated before respiratory arrest had a better chance of survival (57%) compared with only 18% survival rate in patients who were ventilated as an emergency (x2 = 4.47, p < 0.05). Patients who developed other organ failure had higher mortality (71%) than those who did not (22%; x2 = 2.14, p < 0.05). We conclude that patients younger than 50 years of age, who were electively ventilated and without other organ failure had a better immediate survival after assisted ventilation.

Fulltext The outcome of patients with acute bronchial asthma presenting to the emergency room

Yaacob I, Omar R, Mustafa WN

Singapore Med J, 1991 Jun;32(3):166-8.
PMID: 1876890

We collected data on patients above the age of 5 years with acute bronchial asthma who presented to the emergency room of Hospital Sains Universiti Sains Malaysia during the period between 1 January to 31 March 1990. Two hundred and twelve patients (57% males and 43% females) who made a total of 271 visits were recorded. This constitutes 16.3% of all adults and paediatric medical cases seen in the emergency room during this period. The majority of patients presented between 8 pm and 6 am which contrasts with the attendance pattern due to other causes. We also recorded two peak periods of presentation (between 8 pm and 12 midnight and between 6 am and 10 am). Thirty-one (11.4%) cases resulted in admission. Of the 240 cases that were successfully treated and discharged from the emergency room, there were 59 relapses (in 45 patients). Twenty-two percent of the relapses occurred within 24 hours of the last visits. We recorded lower rates of admission as well as relapses compared to all previous studies. Our finding of bimodal pattern of presentations was also not previously reported.

The age question among Asiatic girls in Malayan courts of law

Worth HI

Med J Malaya, 1947;1:252-272.

European standards on height, weight, centres of ossification and date of onset of puberty are not applicable to Asiatic girls in Malaya. " Asiatics " could not be grouped together, racial groups showed differences, especially the three main groups-Chinese, Indians and Malays. Nine tables are furnished showing the average and maximum and minimum heights and weights of the four main groups examined, as well as of some of the minor groups, arranged according to ages from 5 years to 19 years. The conclusion is drawn that the European standard of height and weight is higher than that of any of the Asiatic races in Malaya; a greater difference is noted in the weight than in the height and there is a much greater range in the weight of Asiatics but a smaller range in the height. Onset of menstruation tended to be earlier in the local Asiatic groups than in Europeans. The date of eruption of permanent teeth appeared to be earlier among Asiatic races. No deciduous teeth were found at the age of 12-13 years, the lower second molar was seen in all those examined at that age and the whole lower set was present, excluding the third molar. Earlier efuption of the canine teeth was also noticeable. Details should be consulted in the original by all those interested in medico legal work in tropical countries. P. A. Clearkin.

Correlates between risk perceptions of cervical cancer and screening practice

Wong YL, Chinna K, Mariapun J, Wong LP, Khoo EM, Low WY, et al.

Prev Med, 2013;57 Suppl:S24-6.
PMID: 23318158 DOI: 10.1016/j.ypmed.2013.01.004

OBJECTIVES: To identify the correlates between risk perceptions and cervical cancer screening among urban Malaysian women.
METHOD: A cross-sectional household survey was conducted among 231 women in Petaling Jaya city in 2007. The association of risk perceptions of cervical cancer and screening practice was analyzed using Poisson regression.
RESULTS: 56% of the respondents ever had a Pap smear test. Knowledge of signs and symptoms (aPR=1.11, 95% CI=1.03-1.19), age (aPR=1.02, 95% CI=1.01-1.03), number of pregnancies (aPR=1.06, 95% CI=1.01-1.11), marital status, education level and religion were found to be significant correlates of Pap smear screening. Respondents who were never married were less likely to have had a Pap smear. Those who had no education or primary education were less likely to have had a Pap smear compared to those with degree qualification. The prevalence of screening was significantly higher among Christians and others (aPR=1.35; 95% CI=1.01-1.81) and Buddhists (aPR=1.38; 95% CI=1.03-1.84), compared to Muslims.
CONCLUSION: Eliminating anecdotal beliefs as risks via targeted knowledge on established risk factors and culturally sensitive screening processes are strategic for increasing and sustaining uptake of Pap smear screening versus current opportunistic screening practices.

Knowledge and attitude on childhood hearing loss among mothers and mothers-to-be in urban and rural areas in Malaysia

Wong YA, Mukari SZS, Harithasan D, Mazlan R

Int J Pediatr Otorhinolaryngol, 2019 Sep;124:79-84.
PMID: 31174022 DOI: 10.1016/j.ijporl.2019.05.040

OBJECTIVES: Maternal knowledge and attitude towards childhood hearing loss play an important role in determining the success of early diagnosis and intervention of hearing loss programs in children. This study aimed to 1) assess the knowledge and attitude of childhood hearing loss among mothers, 2) compare knowledge and attitude of childhood hearing loss in urban and rural mothers, 3) investigate the relationship between knowledge and attitude on childhood hearing loss, and 4) identify socio-demographic factors that influence mothers' knowledge and attitude on childhood hearing loss.
METHOD: A cross-sectional survey was conducted on 362 mothers and mothers-to-be (mean age: 31.9 ± 4.9 years, range: 20-48 years old) recruited from Hospital Universiti Kebangsaan Malaysia in Cheras, Kuala Lumpur and two health clinics in Lenggeng, Negeri Sembilan and Beranang, Selangor representing the urban and rural areas respectively. All participants were interviewed in person using a newly developed and reliable questionnaire that tested their knowledge and attitude on childhood hearing loss.
RESULTS: Generally, the majority of mothers had a moderate level of knowledge and positive attitude towards childhood hearing loss. Urban mothers had a significantly higher knowledge than those of the rural area (p

PMID: 6495579

A survey of 61 canine and 26 feline fractures diagnosed between January 1980 and June 1983 at a veterinary teaching hospital was conducted. More than 80 per cent of the fractures occurred in animals less than two years old. Male animals were more frequently involved. In the dog, the femur, tibia, pelvis, radius and ulna were most often affected while in the cat, the femur, mandible, pelvis and spine were more often involved. All the findings were consistent with other reports in the literature.

Serum lipoprotein(A) profiles in a Singaporean population

Wong MS, Chew WL, Aw TC

Pathology, 1999 Aug;31(3):225-9.
PMID: 10503268

Lipoprotein(a) [Lp(a)] is formed when apolipoprotein(a) is linked to low density lipoprotein (LDL)-cholesterol via a single disulfide bond. It is an independent risk factor for myocardial infarction and raised concentrations are associated with an increased risk of developing coronary artery disease. Singapore has a multi-racial population of 77% Chinese, 14% Malays and 7% Indians. Studies have shown that the Indians have significantly higher standardised mortality ratios (SMR) compared to the Chinese and the Malays. We measured serum Lp(a) concentrations in 803 healthy individuals recruited from the Multiphasic Health Screening Programme, using the Macra Lp(a) sandwich enzyme immunoassay kit (Strategics Diagnostics, Delaware, USA). Lp(a) concentrations were skewed in all three groups. Our population mean was 9.0 mg/dl, with 50th, 75th and 95th percentile values of 10.2, 19.8 and 43.1 mg/dl, respectively, which are lower than values reported from Caucasian populations (15.0, 29.0 and 60.0 mg/dl, respectively). Males had lower Lp(a) concentrations than females (P < 0.05). The Indian group had significantly higher concentrations (median 12.3 mg/dl) compared to their Chinese (median 9.6 mg/dl) and Malay (median 8.4 mg/dl) counterparts (P < 0.05). This could partly account for the higher SMR seen in the Indian population in Singapore. As serum Lp(a) concentrations are method- and population-dependent, we recommend that laboratories determine their own reference ranges by their method to avoid misclassification of the coronary heart disease (CHD) risk of patients.

Role of interceptive orthodontics in early mixed dentition

Wong ML, Che Fatimah Awang, Ng LK, Norlian D, Rashidah Dato Burhanudin, Gere MJ

Singapore Dent J, 2004 Dec;26(1):10-4.
PMID: 15736836

Early orthodontic interventions are often initiated in the developing dentition to promote favourable developmental changes and remove or suppress those that are unfavourable. Early interceptive orthodontics can eliminate or reduce the severity of a developing malocclusion, the complexity of orthodontic treatment, overall treatment time and cost. It also improves self-esteem in the subjects and parental satisfaction. Early detection and appropriate referral of cases requiring interceptive orthodontics are important. However, lack of awareness among school children, parents and primary-care personnel (dental nurses and dental officers) may result in patients not being referred for timely interceptive intervention. This article presents a general view of the scope of interceptive orthodontics that can be carried out in early mixed dentition, i.e. when the permanent incisors and molars are erupting into the oral cavity.

Prevalence and factors associated with HIV/AIDS-related stigma and discriminatory attitudes: a cross-sectional nationwide study

Wong LP

Prev Med, 2013;57 Suppl:S60-3.
PMID: 23583477 DOI: 10.1016/j.ypmed.2013.03.013

OBJECTIVE: The prime purpose of this study is to assess HIV/AIDS-related self-stigma and discrimination (S&D) attitudes and associated factors using multivariate analysis of data from the 2010-11 National Survey of Understanding the Root of HIV/AIDS Related Stigma and Discrimination.
METHOD: A national telephone survey was carried out with 2271 of the Malaysian public aged 18-60 years. The sample was contacted by random digit dialing covering the whole of Peninsular Malaysia from December 2010 to May 2011. The HIV-transmission knowledge, HIV-related self-stigma, and public stigma were investigated.
RESULTS: Despite high level of HIV-transmission knowledge [mean (SD)=10.56 (2.42), mean score at 70th percentile] the respondents in this study had moderate levels (mean scores near midpoints) of self-stigma and public stigma attitudes. HIV-transmission knowledge score was not significantly correlated with self-stigma score, but showed a significantly small positive effect (r<0.2) for public stigma scores. Ethnicity is the strongest correlate of HIV-transmission knowledge, self-stigma, and public stigma attitudes in the multivariate analyses. Other significant correlates were age, socioeconomic group, and urban-rural setting.
CONCLUSIONS: The root causes of HIV stigma and discriminatory attitudes were not associated with knowledge deficiency. Interventions should be oriented towards promoting de-stigmatization of HIV/AIDS, and tailored socio-culturally.
