Fulltext Simultaneous omental infarction and acute appendicitis in a child

Koay HT, Mahmoud HE

Med J Malaysia, 2015 Feb;70(1):42-4.

It is crucial to realize that both omental infarction and acute appendicitis can occur simultaneously in the children as both diseases are managed differently. Omental infarction itself is rare in the pediatric group, and its association with acute appendicitis is even rarer. Both diseases usually present with right sided abdominal pain. Ultrasound is the choice of imaging modality in the investigation of abdominal pain in the children. It should not be content if omental infarction is detected, whilst the normal appendix is not seen. We reported a case of simultaneous omental infarction and acute appendicitis in a child who presented with 3 days history of right sided abdominal pain. It was diagnosed preoperatively by ultrasound. Prompt surgical intervention was proceeded and the child made uneventful recovery.

Boo NY, Goh ES

J Trop Pediatr, 1999 Aug;45(4):195-201.

PMID: 10467829

In a case-control study carried out in the Kuala Lumpur Maternity Hospital between 1st July 1995 and 31st January 1996 the objectives were (1) to determine the rate of breastfeeding in surviving very low birthweight (VLBW, < or = 1500 g) Malaysian infants following the introduction of the Baby Friendly Hospital Concept, and (2) to identify significant predictors associated with successful breastfeeding in these infants. During the study period, 201 (1.24 per cent) of live-born infants were VLBW infants, 192 (95.5 per cent) were Malaysians, and 141 (73.4 per cent) of them survived to go home. The breastfeeding rate among all surviving VLBW Malaysian infants at the time of discharge was 40.2 per cent (57/141). The mothers of 126 (89.4 per cent) VLBW Malaysian infants were interviewed before discharge. Logistic regression analysis showed that, after controlling for various confounders, the significant predictors associated with successful breastfeeding were: (a) Malay mothers (odds ratio: 6.0; 95 per cent CI: 1.9, 19.4), (b) mothers with educational levels of between 7 and 9 years (odds ratio: 3.6; 95 per cent CI: 1.0, 12.2), and (c) earlier age of commencement of enteral feeds in the VLBW infants (for each additional day delay in commencement of feeding, odds ratio of breastfeeding was 0.5; 95 per cent CI: 0.4, 0.8).

The patterns and transmissibility of antibiotic resistance among clinical strains of Pseudomonas aeruginosa

Palillo ES, Salleh MA

Microbiol. Immunol., 1992;36(11):1195-200.

PMID: 1491621

Four hundred and ninety-eight predominantly pyocin-type 10 clinical strains of Pseudomonas aeruginosa were analyzed for resistance to carbenicillin, cefoperazone, cefotaxime, ceftazidime, gentamicin, amikacin and netilmicin. Based on NCCLS-recommended MIC breakpoints, 245 strains were found to be resistant, of which 41.6% were resistant to carbenicillin, 38% to gentamicin, 37.8% to netilmicin, 26.3% to cefoperazone, 17.9% to cefotaxime, 0.6% to amikacin and none to ceftazidime. Quadruple resistance to carbenicillin, cefoperazone, gentamicin and netilmicin was the most frequent pattern observed. Resistance to older antibiotics (kanamycin, streptomycin and tetracycline) and to mercuric chloride were also common. Conjugation experiments suggested that self-transmissible and non-transmissible plasmids occurred in at least 66 strains.

Could hypertension possibly be adaptive?

Prakash ES, Fink GD

Clin Exp Pharmacol Physiol, 2010 Feb;37(2):e99-e106.

1. We believe that the ultimate goal of cardiovascular regulatory mechanisms is not the regulation of arterial blood pressure (BP), but the maintenance of tissue blood flows commensurate with metabolic requirements. Thus, elevated BP can potentially contribute to optimizing tissue blood flows under select circumstances; for example, when there are primary defects in autoregulation of tissue blood flows. 2. The hypothesis that a primary defect in autoregulation of tissue blood flows may be responsible for the development of hypertension is presented. It is argued that, in this context, at least part of the rise in BP may be reflexly driven by a 'metaboreflex', a homeostatic mechanism acting to regulate tissue blood flows. 3. We argue that in the context of primary defects in autoregulation of tissue blood flows, the ability to generate and sustain a hypertensive phenotype increases the lifespan of species (i.e. if it were not for this adaptive hypertensive phenotype, death due to circulatory failure would occur much earlier). 4. Experimental and clinical evidence that indirectly supports the hypothesis is reviewed briefly and a means for testing this hypothesis is suggested.

Fulltext Nutritional assessment of rural villages and estates in Peninsular Malaysia: I Socio-economic profile of households

Chee H, Khor G, Tee ES

Malays J Nutr, 1997 Mar;3(1):1-19.

PMID: 22692232 MyJurnal

A nutritional study was carried out on six (five rural and one urban) low income groups in Peninsular Malaysia from 1992-1995. In this paper, the socio-economic data for the five rural groups - padi farmers, rubber smallholders, coconut smallholders, estate workers, and fishermen - are presented. With the exception of the estate workers, the sample was predominantly Malay, with an overall mean household size of 5.30. Household incomes were generally low, and 47% of all households had incomes that were below the poverty line income (PLI) of RM405. Based on this PLI, the prevalence of poverty was above 50% among the padi, rubber, coconut, and fishing households. Nevertheless, the study population appeared to be better off in terms of the other indicators examined. Poultry rearing, for example, was widespread in the padi, rubber, and coconut villages; 65% of all households owned at least one motorised vehicle, 53% owned a refrigerator, and 83% owned a television set. Furthermore, over 80% of all households had access to piped water, 96% had electricity supply, and over 90% had a flush or pour-flush latrine. In comparison to the 1979-1983 poverty villages study (Chong et al., 1984), the households in the current study enjoyed better living conditions. Strict comparisons between the two studies, however, is difficult owing to the different criteria adopted in the selection of the study villages.

Armstrong HE, Tan ES

Med Educ, 1979 Mar;13(2):99-102.

PMID: 431423 DOI: 10.1111/j.1365-2923.1979.tb00930.x

Behavioural self-analysis projects were introduced into the second year medical curriculum in behavioural sciences at the University of Malaya. Students performance and evaluation of the experience were compared with those of American medical students. It was concluded that receptivity of medical students to principles of behaviour therapy is relatively similar in the two societies.

Fulltext The roles of men in family planning - a study of married men at the UKM primary care clinic

Ling JES, Tong SF

Malays Fam Physician, 2017;12(1):2-13.

PMID: 28503268

INTRODUCTION: Traditionally, family planning initiatives were concentrated on women despite it being a family matter. As family dynamics evolved over the years, fathers' involvement in family planning has become crucial in enhancing the family well-being.
OBJECTIVES: This study aimed to identify the role played by men in family planning activities and the association of socio-economic characteristics with these roles.
METHODOLOGY: This was a cross-sectional study carried out in a university primary care clinic. All married male attendees to the clinic, aged 50 years and below, were approached to answer a set of self-administered questionnaires, asking for their involvement in family planning practices. The data were analysed using descriptive and inferential statistics.
RESULTS: There were 167 participants in the study. A high proportion of men participated in the discussions regarding previous pregnancies (60.42%), future child planning (89.76%) and desired family size (89.76%). However, the discussions on the usage of family planning methods (FPMs; 39.16%) were significantly low. Socio-economic factors associated with higher likelihood of men discussing family planning activities were older age (p < 0.0), higher education level (p = 0.010), higher monthly income (p < 0.001) and longer duration of marriage (p = 0.0049).
CONCLUSIONS: The level of participation of men varied in the discussions of four family planning activities. The roles taken by men in family planning were associated with older age and higher socio-economic class. The majority of men needs to be encouraged to play a more active role in the discussion of FPMs.

Type 2 diabetes mellitus in Malaysia: current trends and risk factors

Tee ES, Yap RWK

Eur J Clin Nutr, 2017 07;71(7):844-849.

PMID: 28513624 DOI: 10.1038/ejcn.2017.44

This review discussed the prevalence of diabetes mellitus (DM) in Malaysia and the associated major risk factors, namely overweight/obesity, dietary practices and physical activity in both adults and school children. Detailed analyses of such information will provide crucial information for the formulation and implementation of programmes for the control and prevention of T2DM in the country. National studies from 1996-2015, and other recent nation-wide studies were referred to. The current prevalence of DM in 2015 is 17.5%, over double since 1996. Females, older age group, Indians, and urban residents had the highest risk of DM. The combined prevalence of overweight/obesity in 2015 is 47.7% for adults. Adults did not achieve the recommended intakes for majority of the foods groups in the Malaysian Food Pyramid especially fruits and vegetables. Adults also had moderate physical activity level. Three nation-wide studies showed a prevalence ranging from 27 to 31% for combined overweight/obesity in school children. The prevalence was higher among boys, primary school age, Indian ethnicity, and even rural children are not spared. Physical activity level was also low among school children. There must be serious systematic implementation of action plans to combat the high prevalence of diabetes and associated risk factors.

Contactless respiration rate measurement using optical method and empirical mode decomposition

Gan KB, Yahyavi ES, Ismail MS

Technol Health Care, 2016 Sep 14;24(5):761-8.

PMID: 27163300 DOI: 10.3233/THC-161161

BACKGROUND: At the emergency triage center, assessment of the present of the danger signs and measurement of vital signs are measured according to the guidelines. The respiration rate is still posing a challenge to the doctor as it is impractical to use conventional devices. Attaching measurement devices to the patient will induce artificial measurements (self-awareness stress effects) besides being time-consuming. Currently, the medical officers visually count the number of times the chest movement in a minute, sometimes poses cultural challenges especially for female patients.

OBJECTIVE: The main objective of this paper is to develop a robust algorithm to extract respiration rate using the contactless displacement sensor.

METHODS: In this study, chest movements were used as an indicative of inspiration and expiration to measure respiratory rate using the contactless displacement sensor. The contactless optical signals were recorded from 32 healthy subjects in four different controlled breathing conditions: rest, coughing, talking and hand movement to obtain the motion artifacts that the patients may have in the emergency department. The Empirical mode decomposition (EMD) algorithm was used to derive continuous RR signal from the contactless optical signal.

RESULTS: The analysis showed that there is a good correlation (0.9702) with RMSE of 0.33 breaths per minutes between the contact respiration rate and contactless respiration rate using empirical mode decomposition method.

CONCLUSION: It can be concluded that the empirical mode decomposition method can extract the respiration rate of the contactless optical signal from chest movement.

Simplifying four-strand flexor tendon repair using double-stranded suture: a comparative ex vivo study on tensile strength and bulking

Low TH, Ahmad TS, Ng ES

J Hand Surg Eur Vol, 2012 Feb;37(2):101-8.

PMID: 21636621 DOI: 10.1177/1753193411409840

We have compared a simple four-strand flexor tendon repair, the single cross-stitch locked repair using a double-stranded suture (dsSCL) against two other four-strand repairs: the Pennington modified Kessler with double-stranded suture (dsPMK); and the cruciate cross-stitch locked repair with single-stranded suture (Modified Sandow). Thirty fresh frozen cadaveric flexor digitorum profundus tendons were transected and repaired with one of the core repair techniques using identical suture material and reinforced with identical peripheral sutures. Bulking at the repair site and tendon-suture junctions was measured. The tendons were subjected to linear load-to-failure testing. Results showed no significant difference in ultimate tensile strength between the Modified Sandow (36.8 N) and dsSCL (32.6 N) whereas the dsPMK was significantly weaker (26.8 N). There were no significant differences in 2 mm gap force, stiffness or bulk between the three repairs. We concluded that the simpler dsSCL repair is comparable to the modified Sandow repair in tensile strength, stiffness and bulking.

Fulltext Student perceptions regarding the usefulness of explicit discussion of "Structure of the Observed Learning Outcome" taxonomy

Prakash ES, Narayan KA, Sethuraman KR

Adv Physiol Educ, 2010 Sep;34(3):145-9.

PMID: 20826769 DOI: 10.1152/advan.00026.2010

One method of grading responses of the descriptive type is by using Structure of Observed Learning Outcomes (SOLO) taxonomy. The basis of this study was the expectation that if students were oriented to SOLO taxonomy, it would provide them an opportunity to understand some of the factors that teachers consider while grading descriptive responses and possibly develop strategies to improve scores. We first sampled the perceptions of 68 second-year undergraduate medical students doing the Respiratory System course regarding the usefulness of explicit discussion of SOLO taxonomy. Subsequently, in a distinct cohort of 20 second-year medical students doing the Central Nervous System course, we sought to determine whether explicit illustration of SOLO taxonomy combined with some advice on better answering descriptive test questions (to an experimental group) resulted in better student scores in a continuous assessment test compared with providing advice for better answering test questions but without any reference to SOLO taxonomy (the control group). Student ratings of the clarity of the presentation on SOLO taxonomy appeared satisfactory to the authors, as was student understanding of our presentation. The majority of participants indicated that knowledge of SOLO taxonomy would help them study and prepare better answers for questions of the descriptive type. Although scores in the experimental and control group were comparable, this experience nonetheless provided us with the motivation to orient students to SOLO taxonomy early on in the medical program and further research factors that affect students' development of strategies based on knowledge of SOLO taxonomy.

Ravindra P, Chan ES, Reddy KU

Int J Food Sci Nutr, 2007 Nov;58(7):542-7.

PMID: 17852467

Extensive studies have been carried out on the effect of temperature and salt concentration on the theological behavior of whey proteins and different starches individually, but not on mixed dispersions of whey protein isolates and starches. In the present studies, the rheological behavior of cross-linked waxy maize starch and whey protein isolate mixed dispersions during heating at 60-85 degrees C was investigated. Further, the effect of CaCl2 (25-100 mM ionic strengths) on the gelatinization of these dispersions was determined. It was found that at a 2:3 ratio and a 3:2 ratio of cross-linked waxy maize starch to whey protein isolate mixed gels form a compatible networkmM concentration the solution viscosity was higher.
