Predictors of duodenal eosinophil counts among subjects undergoing diagnostic endoscopy.

Introduction: Duodenal eosinophilia has been implicated in the pathophysiology of functional dyspepsia. In a retrospective observational study, we previously reported that duodenal eosinophilia (as defined by a mucosal count of greater than 15 eosinophils per 5 high power fields), was associated with symptomatic erosive gastroesophageal reflux disease (GERD), concomitant co-morbidities and Chinese ethnicity but not functional dyspepsia among 289 multiracial subjects undergoing diagnostic endoscopy in 2019 before the COVID-19 pandemic. We tested the reproducibility of those findings on a larger sample that included the original cohort and another 221 subjects who underwent endoscopy in 2022 after the easing of pandemic restrictions.

Duodenal eosinophilia is associated with symptomatic erosive gastro-oesophageal reflux disease, presence of co-morbidities, and ethnicity but not undifferentiated functional dyspepsia: A retrospective Malaysian study.

Background: Duodenal eosinophilia is postulated to play a key role in the pathogenesis of functional dyspepsia, a common condition responsible for considerable impairment of quality of life. Our objective was to evaluate the relative strength of the associations between duodenal eosinophilia, functional dyspepsia, symptomatic erosive gastroesophageal reflux disease (GERD), the presence of co-morbidities, and a number of other variables.

Methods: Eosinophil counts of archived endoscopic duodenal biopsies of 289 subjects were determined by a pathologist blinded to the clinical data.

A retrospective audit of endoscopic duodenal biopsies to uncover undetected Coeliac disease in Malaysian patients.

Background: Coeliac disease, an autoimmune enteropathy related to gluten sensitivity was hitherto thought to be rare in Asia. Recent data however suggests that Celiac disease may be under-diagnosed in Asia.

Objective: The aim of this audit was to determine the frequency of histological changes compatible with Coeliac disease among patients undergoing elective diagnostic oesaphago-gastro-duodenoscopy (OGDS) under the care of a single practitioner in a Malaysian hospital.

Is lactate lower in septic patients who are prescribed beta blockers? Retrospective cohort study of an intensive care population.

Objective: Elevated serum lactate has long been considered an important marker of sepsis severity. Increasing evidence supports catecholamine-stimulated aerobic glycolysis being a major contributor to the hyperlactataemia seen in sepsis. Beta-blockade may blunt such catecholamine mediated rise in lactate analogous to the way it can mask tachycardia.

Helicobacter pylori infection--a boon or a bane: lessons from studies in a low-prevalence population.

Helicobacter pylori (H. pylori) infection is etiologically associated with gastric cancer and peptic ulcer diseases which are both important public health burdens which could be largely eliminated by H. pylori eradication.

Towards understanding the low prevalence of Helicobacter pylori in Malays: genetic variants among Helicobacter pylori-negative ethnic Malays in the north-eastern region of Peninsular Malaysia and Han Chinese and South Indians.

Objectives: To identify gene polymorphisms that differ between Malays, Han Chinese and South Indians, and to identify candidate genes for the investigation of their role in protecting Malays from Helicobacter pylori (H. pylori) infection.

Methods: Malay participants born and residing in Kelantan with a documented absence of H.

Sociocultural and dietary practices among Malay subjects in the north-eastern region of Peninsular Malaysia: a region of low prevalence of Helicobacter pylori infection.

Background And Aim: The prevalence of Helicobacter pylori infection is exceptionally low among the Malays in the north-eastern region of Peninsular Malaysia. The reasons are unknown. Our aim was to compare environmental factors that differed in relation to H.

Barrett's Esophagus in an Area with an Exceptionally Low Prevalence of Helicobacter pylori Infection.

Objective. This study was undertaken to gain an insight into the relationship between Helicobacter pylori (H. pylori) infection, Barrett's esophagus and reflux esophagitis in an area of exceptionally low prevalence of H.

Incidence of esophageal carcinoma among Malays in North-Eastern Peninsular Malaysia: an area with an exceptionally low prevalence of Helicobacter pylori infection.

Background: Obesity, gastroesophageal reflux, and Barrett's esophagus have all been linked to esophageal adenocarcinoma. In addition, the decline in Helicobacter pylori (H. pylori) infection in affluent societies has also been suggested to be a major factor in the recent rise in the incidence of esophageal adenocarcinoma.

Chronic atrophic antral gastritis and risk of metaplasia and dysplasia in an area with low prevalence of Helicobacter pylori.

Introduction: The Northeastern region of Peninsular Malaysia is an area with exceptionally low prevalence for Helicobacter pylori infection. The risk of intestinal metaplasia and dysplasia in patients with chronic atrophic gastritis (CAG) and its association with Helicobacter pylori is unknown in this region.

Methods: This was a cross-sectional study on gastric biopsies from 234 consecutive patients (mean age 53.

The effect of propranolol in malay patients with liver cirrhosis - a pharmacodynamic evaluation.

The pharmacodynamics of propranolol were studied in 12 cirrhotic Malay patients. Fifteen healthy Malay volunteers were selected and several clinical parameters were obtained. The effects of three doses of propranolol in reducing the heart rate (HR) of these patients were observed to be significantly different.

Trichuriasis: localized inflammatory responses in the colon.

Most patients with trichuriasis have light worm burdens. Data regarding the inflammatory response to Trichuris worms in the colon of lightly infected persons are scant. Nine patients whose Trichuris infection was found by colonoscopy had biopsies taken from a site adjacent to visible worms and from a second site some 20 cm distally.

A study of the concordance between endoscopic gastritis and histological gastritis in an area with a low background prevalence of Helicobacter pylori infection.

The concordance between endoscopic and histological gastritis was determined in 52 patients referred for upper gastrointestinal endoscopy. The study was conducted in Northeastern Peninsular Malaysia, an area with a low background prevalence of H. pylori infection.

The Pharmacokinetics of Single Dose vs Steady-State Doses of Propranolol in Cirrhotic Malay Patients.

Pharmacokinetics of propranolol (PRN) given orally were studied in twelve cirrhotic Malay patients [10 males, 2 females], aged 33-62 years [49.83±9.17], body weight 39-72 kg [58.

Trichuris Dysentery Syndrome: evidence that it may be underdiagnosed in Kelantan.

The prevalence rate of trichuriasis in children in certain areas of Kelantan is high. However the Trichuris Dysentery Syndrome (TDS), a condition in children characterized by chronic diarrhoea, stunting and anaemia is said to be rare. A recent change in policy at our institution to lower the threshold for undertaking colonoscopy in children with chronic diarrhoea resulted in the detection of 6 cases of TDS in less than a year.

Management of Helicobacter pylori infection--a Working Party Report of the Malaysian Society of Gastroenterology and Hepatology.

The Working Party Report on the Management of Helicobacter pylori serves as a clinical practice guideline for Malaysian doctors. H. pylori is not uncommon in the Malaysian population.

Intestinal geohelminthiasis and growth in pre-adolescent primary school children in Northeastern Peninsular Malaysia.

A cohort of one hundred 8-9 year old school children in Northeastern Peninsular Malaysia underwent stool examination, weight and height measurements. Seventy-three children were infected with Ascaris lumbricoides and/or Trichuris trichiura. All infected children were treated with albendazole at baseline, 6 months and 9 months.

Intestinal helminthiasis in relation to height and weight of early primary school children in northeastern peninsular Malaysia.

Stool examination, height and weight measurements were undertaken on 249 early primary school children at two schools in North-eastern Peninsular Malaysia. Helminth infected children were treated and follow-up anthropometric measurements and stool examination undertaken on all (n = 100) children at one of the schools 16 months later; to observe the relationship between acquisition of infection and growth. Baseline Ascaris prevalence rates at the two schools were 16.

Left ventricular outflow tract (LVOT) vegetations and spontaneous obliteration of a large ruptured intracranial mycotic aneurysm in a case of infective endocarditis.

A 10-year-old girl with mild aortic regurgitation presented with cerebral infarction. Two-dimensional echocardiography showed vegetations on the septal wall of the left ventricular outflow tract without involvement of the aortic valve itself. After successful antibiotic treatment the patient developed an intra-cranial haemorrhage due to rupture of a large intracranial mycotic aneurysm.

Intestinal helminthiasis and abdominal symptoms in adults.

In a study to test the association between soil transmitted intestinal helminthiasis and abdominal symptoms in a non-paediatric age group, 242 randomly selected patients (137 males, 105 females, median age 45 years) were asked specific questions pertaining to abdominal symptoms at the time of admission to the adult medical wards. Stool examination on all patients revealed a round worm prevalence rate of 21%. A larger proportion of stool positive female patients were symptomatic than stool negative females (68% vs 30%, p = 0.
