Abdominal obesity (AO) is an independent risk factor for cardiovascular disease, hypertension and diabetes mellitus in adults. There is a lack of data on the magnitude and socio-demographic profile of AO among Malaysian adults at the national level. In the Third National Health and Morbidity Survey (NHMS III) conducted in 2006, AO of adults aged 18 years(More)
Intracellular microelectrode techniques were employed to characterize the blocker sensitivity of the K+ conductance (gK) at the apical membrane of the toad retinal pigment epithelium (RPE). Increasing the K+ concentration in the apical bath ([K+]o) from 2 to 5 mM produced a rapid depolarization of the apical membrane potential (VA). The addition of 0.5 mM(More)
The Third National Health and Morbidity Survey (NHMS III) was conducted in 2006 on a nationally representative sample of population in Malaysia. Over 21,000 children aged 0-17.9 years were measured for body weight and stature according to the protocol of the World Health Organization. This article describes the nutritional status of children aged 0-59.9(More)
Pott's puffy tumor is rarely associated with orbital cellulitis. We describe a pediatric patient with Pott's puffy tumor and right-sided orbital cellulitis. He underwent urgent surgical drainage of a glabellar subperiosteal abscess and completed a six week course of intravenous antibiotics with complete resolution of infection and no long-term sequelae.(More)
The National Health and Morbidity Survey III 2006 wanted to perform anthropometric measurements (length and weight) for children in their survey. However there is limited literature on the reliability, technical error of measurement (TEM) and validity of these two measurements. This study assessed the above properties of length (LT) and weight (WT)(More)
The retinal pigment epithelium is a transporting epithelium that helps regulate the volume and composition of the subretinal space surrounding photoreceptor outer segments. The capacity of the RPE to actively transport Na+ and K+ between the retina and the blood supply depends on the localization of the Na+, K(+)-ATPase to the apical membrane, but in(More)
Alloplastic orbital implants are commonly used by surgeons in the repair of orbital wall defects. They are generally well tolerated, but they may cause late-onset complications. The authors present the case of a 65-year-old man with a history of left orbital floor fracture repair 25 years prior using a silicone orbital implant. He presented with a 1-year(More)
This study sought to examine the reliability of two measurements; Calf Circumference (CC) and Mid-half Arm Span (MHAS). A sample of 130 elderly persons aged 60 years and above seen consecutively in the Kuala Lumpur Hospital outpatient clinic during the period of December 2005 to January 2006, upon consent, were recruited to the study. There was a high(More)
A 48-year-old woman presented with a 5-month history of unilateral epiphora and progressive growth of a left-sided medial canthus mass. CT revealed a nonenhancing soft tissue mass of the left lacrimal sac with widening and erosion of the nasolacrimal canal. The tumor was resected and pathologically confirmed to be malignant melanoma. Despite wide resection(More)
INTRODUCTION The Third National Health and Morbidity Survey Malaysia 2006 includes a nutritional status assessment of children. This study aimed to assess the inter- and intra-examiner reliability, the technical error of measurement and the validity of instruments for measuring weight, height and waist circumference. METHODS A convenience sample of 130(More)
