PMID: 12733200

The New Integrated Curriculum at the Faculty of Medicine, University of Malaya, Which comprises three major longitudinal strands, was first implemented in 1998 to provide better integration of clinical and basic medical sciences. One of these longitudinal strands, the Doctor, Patients, Health and Society (DPHS) module, emphasizes the importance of developing good communication skills as well as introducing students to behavioural sciences, public health medicine, statistics and epidemiology. Community Family Case Studies (CFCS), within this module, have been used as a means for students to focus on these aspects, as the students are introduced to patients, their families and their community in Year 1 of the medical course and are required to follow them up throughout their five-year training period.

The effect of selected high pressure processing (HPP) parameters on the sensory attributes and
shelf life of jackfruit bulb packed using vacuum skin (VS) and vacuum nylon (VN) packaging
was studied. The samples were stored at chilled temperature (4°C) for shelf life study. HPP
significantly (p < 0.05) increased the shelf life of VS- and VP-packed jackfruit bulbs to 60 d
during chilled storage. In terms of colour stability during storage, both VS- and VP-packed
HP-treated jackfruit bulbs exhibited no significant differences (p > 0.05) in L*, a*, and b*
values. Also, the VS- and VP-packed HP-treated samples exhibited no significant differences
(p > 0.05) in terms of texture. However, the sensory evaluation carried out among 48 panellists
showed that there were significant differences (p < 0.05) between the untreated and HP-treated jackfruit bulbs. The aforementioned results had proven that HPP treatment of 500 MPa for
5 min could successfully extend the shelf life and retain the physicochemical properties of
jackfruit bulbs, regardless of the types of packaging used.

Do fertility intentions predict subsequent behavior? Evidence from Peninsular Malaysia

Tan PC, Tey NP

Stud Fam Plann, 1994 Jul-Aug;25(4):222-31.

PMID: 7985216 DOI: 10.2307/2137905

Data from the 1984 Malaysian Population and Family Survey were matched with birth registration records for 1985-87 to determine the accuracy of statements regarding desired family size that were reported in a household survey in predicting subsequent reproductive behavior. The findings of this study were that stated fertility intention provides fairly accurate forecasts of fertility behavior in the subsequent period. In other words, whether a woman has another child is predicted closely by whether she wanted an additional child. Informational, educational, and motivational activities of family planning programs would, therefore, have greater success in reducing family size if fertility intentions were taken into account.

Changing patterns of marriage and household formation in Peninsular Malaysia

PMID: 12283691

"Based on surveys conducted among different ethnic groups in rural and urban settings in Peninsular Malaysia in 1981-82, this paper analyses changes in patterns of marriage and household formation among Malays, Chinese, and Indians. Aspects covered include social mixing before marriage, choice of spouse, comparison of spouses' characteristics, and place of residence after marriage. There are important cultural differences between the main Malaysian ethnic groups in matters related to marriage, but in many important respects, attitudes and practice are tending to converge...."

Fibroadenomatoid mastopathy: another distractive breast lesion?

Tan PE, Looi LM

Malays J Pathol, 1991 Dec;13(2):101-4.

PMID: 1823090

Although most anatomical pathologists have encountered breast lesions with the composite histological features of fibroadenoma (FA) and fibrocystic change (FC), referred to as fibroadenomatosis or fibroadenomatoid mastopathy (FAM), little is known about its prevalence or clinico-pathological significance. In a retrospective histological review of 400 consecutive breast lesions, among both East and West Malaysians, coded either as FA or FC in the files of the Department of Pathology, University of Malaya, we found 45 (11.3%) cases of FAM. Typically, FAM lesions showed fibroadenomatoid foci in a background of fibrocystic change. The finding of FAM among lesions coded as FC was higher (18.5%) than among FA (4%). The mean age of patients with FAM (32.1 years) was similar to FC (35.1 years) but significantly older than that of FA (26.1 years). The notion that FA and FC are lesions at two ends of a spectrum of growth disorder of breast related to oestrogen-progesterone interplay, and that FAM occupies a position intermediate between the two, may explain its morphological and age patterns, but remains speculative. It is hoped that increasing awareness of this condition will lead to better understanding of breast pathophysiology. Nevertheless, until its biological nature, histogenesis and malignant potential are more clearly understood, defining FAM as a distinct form of breast disease may not be meaningful to patient management.

Fulltext Ocular toxoplasmosis in Malaysia

Lim VKE, Tan PL

Med J Malaysia, 1983 Sep;38(3):185-7.

PMID: 6672558

31 cases of ocular toxoplasmosis were seen at the Ophthalmology Clinic, Uniuersiti Kebangsaan Malaysia, Kuala Lumpur during a one-and-a-half year period. All these cases were diagnosed as congenital ocular toxoplasmosis. As this condition appears not to be uncommon in. Malaysia, greater effort should be made towards its prevention especially among pregnant women.

Clinical efficacy of sulfadoxine-pyrimethamine in the treatment of falciparum malaria in Sabah, Malaysia

Tan HS, Tan PE

Ann Acad Med Singap, 1984 Apr;13(2):170-4.

PMID: 6388486

One hundred and ten consecutive patients with falciparum malaria were treated with Fansidar and primaquine. Of the 61 patients who were followed up at one week, 4 (6.6%) failed to clear their parasitaemia (1 R III and 3 R II treatment failures). Of the subsequent 40 patients who were seen again at one month, another 3 (7.5%) had recrudesced (R I treatment failure). A total of 7 patients thus experienced some form of treatment failure in the cohort of 40 who completed the one month follow up. Only 1 of these 7 patients (with R III treatment failure) failed to respond to repeat Fansidar treatment, and may be the only one with true Fansidar resistance. The overall treatment failure rate of 17.5% (95% confidence interval: 6-29%) in the cohort who completed the study is consistent with the known clinical efficacy of Fansidar. These results suggest no significant Fansidar resistance in falciparum malaria found in Sabah.

Fulltext Outcome of neonates admitted to special care nursery, University Hospital, Kuala Lumpur: a comparison of two periods

Toh CK, Tan PC, Chan YK

Med J Malaysia, 1984 Mar;39(1):21-7.

PMID: 6513836

The overall mortality rate of babies delivered in the University Hospital, Kuala Lumpur has improved significantly from 18.5 in 1969-1971 to 9.9 per thousand live births in 1979-1981. This drop in mortality is also seen in those infants weighing 1001 - 2000 g at birth. Indian babies in the weight group 1001 - 1500 g at birth appear to have a significantly lower mortality than the other races. Babies referred from outside have a much higher mortality rate compared to babies delivered in University Hospital, Kuala Lumpur.

Saha N, Tan PY, Tan BH

Z Morphol Anthropol, 1980;71(1):107-9.

PMID: 6969497

1829 school-boys of Singapore comprised of 849 Chinese, 469 Malays and 511 Indians were investigated for the incidence of red-green colour-blindness with Ishihara's plates. The incidence of red-green colour-blindness was found to be 3.8%, 4.5% and 4.5%, respectively in Chinese, Malay and Indian boys. The incidence among the different dialect groups was variable with the highest incidence of red-green colour-blindness among Mandarin speaking group (14.3%), followed by Hainanese speaking (6.7%) and other dialect groups of Chinese (2.8% to 4.5%). The incidence of red-green colour-blindness was higher in the older boys compared with the younger boys when all the three ethnic groups are combined.

Effect of FTO rs9930506 on obesity and interaction of the gene variants with dietary protein and vitamin E on C-reactive protein levels in multi-ethnic Malaysian adults

Mitra SR, Tan PY, Amini F

J Hum Nutr Diet, 2018 12;31(6):758-772.

PMID: 30141234 DOI: 10.1111/jhn.12593

BACKGROUND: Individual variations of obesity-related traits can be a consequence of dietary influence on gene variants.

METHODS: This cross-sectional study aimed to evaluate (i) the effect of FTO rs9930506 on obesity and related parameters and (ii) the influence of diet on the above association in Malaysian adults. In total, 79 obese and 99 nonobese Malaysian adults were recruited.

RESULTS: In comparison with Chinese and Malays, Indians had significantly higher waist circumference (P ≤ 0.001 and P = 0.016), waist-hip ratio (P = 0.001 and P < 0.001), body fat percentage (P = 0.001 and P = 0.042), fasting insulin (P = 0.001 and P = 0.001), homeostatic model assessment-insulin resistance (P = 0.001 and P = 0.001) and lower high-density lipoprotein-cholesterol levels (P < 0.001 and P < 0.001), respectively. Indians consumed significantly lower dietary cholesterol (P = 0.002), percentage energy from protein (P < 0.001) and higher fibre (P = 0.006) compared to the other two groups. Malaysian Indians expressed the highest risk allele frequency (G) of FTO rs9930506 compared to the Malays and the Chinese (P < 0.001). No significant association was found between FTO rs9930506 and obesity (dominant model). Risk allele carriers (G) consumed significantly lower vitamin E (P = 0.020) and had a higher fibre intake (P = 0.034) compared to the noncarriers (A). Gene-diet interaction analysis revealed that risk allele carriers (G) had lower high sensitivity C-reactive protein (hsCRP) levels with higher energy from protein (≥14% day-1 ; P = 0.049) and higher vitamin E (≥5.4 mg day-1 ; P = 0.038).

CONCLUSIONS: The presence of the risk allele (G) of FTO rs9930506 was not associated with an increased risk of obesity. Malaysian Indians had a significantly higher frequency of the risk allele (G). Indian participants expressed higher atherogenic phenotypes compared to Chinese and Malays. FTO rs9930506 may interact with dietary protein and vitamin E and modulate hsCRP levels.

Fulltext Coitus and orgasm at term: effect on spontaneous labour and pregnancy outcome

Tan PC, Yow CM, Omar SZ

Singapore Med J, 2009 Nov;50(11):1062-7.

PMID: 19960160

INTRODUCTION: Coitus and orgasm in late pregnancy are believed to facilitate the onset of labour. We aim to evaluate the relationship at term of reported coitus and orgasm with spontaneous labour.
METHODS: Women at term scheduled for non-urgent labour induction were asked to keep a coitus and orgasm diary. These women were recruited for a randomised trial on the effect of coitus to promote spontaneous labour. For this analysis, the women were categorised into coitally-active and abstinent groups according to their coital diary. Spontaneous labour prior to the date of scheduled labour induction was the primary outcome. Labour, delivery and neonatal outcome were also evaluated. Multivariable logistic regression analysis was used to control for significant variables.
RESULTS: On univariate analysis, the inverse association of coitus with spontaneous labour was borderline (odds ratio [OR] 0.6; 95 percent confidence interval [CI] 0.3-1.0; p-value is 0.052). Orgasm was not associated with spontaneous labour (p-value is 0.33). After adjustment, coitus (adjusted OR 0.4; 95 percent CI 0.2-0.8; p-value is 0.009) displayed a significant inverse association with spontaneous labour. Coitus and orgasm were not associated with any other adverse pregnancy outcome.
CONCLUSION: Women who reported coitus were less likely to go into spontaneous labour prior to their scheduled labour induction. Reported coitus and orgasm were not associated with adverse pregnancy outcome.
