    This is a cross-sectional study on 218 pregnant mothers in an urban government Hospital.The study aimed to assess knowledge, attitudes and sources of information on breastfeeding. The results could be utilised to promote breastfeeding. Almost all the respondents (96.8%) intended to breastfeed their newborns. Most of them (74.8%) were knowledgeable about breastfeeding i.e. colostrum and breast milk was the best food, good for resistance against disease and allergy, filling up stomach easily, helpful in teeth development and maternal recovery after birth, increased bonding, was easy and economical. The two main misconceptions were mothers would stop breastfeeding when infant or mother was sick, and giving clear fluid to the exclusively breastfed infants to prevent dehydration. Most mothers (83.9%) responded positively towards breastfeeding i.e. it was easier than infant formula, had no negative effect on marital relationship or family care, would commence breastfeeding straight after delivery, agreeable to the banning of bottles and teats in hospital and they would not stop breastfeeding even if husband discouraged them. Only 56.9% of the mothers believed they could breastfeed their babies with modesty anywhere. The main sources of information were attained from the mass media (34.9%), antenatal class (32.1%) and other mothers with breastfeeding experiences.

  2. Fulltext Malays in peninsular Malaysia may have the lowest incidence of stomach cancer in the world
    Lim KG
    Med J Malaysia, 2009 Mar;64(1):91-2.
    PMID: 19852334 MyJurnal
    The Malaysian National Cancer Registry (NCR) report for the period 2003-2005 shows an incidence of stomach cancer of 2.2 for Malay, 11.3 for Chinese and 11.9 for Indian males per 100,000 population. Malay (1.3), Chinese (7.2) and Indian (7.2) women have rates lower than men. Malays in Peninsular Malaysia have five times less stomach cancer than Chinese and Indians. This racial difference is more marked than that noted in the Singapore cancer registry. Regional data from Kelantan has an even lower rate for Malays there (1.5 for males and 0.9 for females per 100,000 population). The incidence of Helicobacter pylori infection, a known risk factor for stomach cancer, is low among Malays.

    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 53.5 [14.8] years) who underwent upper gastrointestinal endoscopy between January 2006 and December 2006.

    RESULTS: There were 137 (59%) men and 185 (79%) Malay patients. Among 234 biopsies, CAG was found in 99 and non-atrophic gastritis in 135. Intestinal metaplasia and dysplasia were detected in 8 and 6 atrophic gastritis biopsies, respectively, and in 10 and 3 of non-atrophic gastritis biopsies, respectively. H. pylori were detected in 16 (9 Malays, 7 non- Malays) biopsies (p=0.024); intestinal metaplasia was detected in 4 biopsies (p=0.3) and dysplasia in 5 biopsies (p=0.3). Of the 218 biopsies negative for H. pylori, intestinal metaplasia was found in 14 and dysplasia in 4. The risk of intestinal metaplasia as well as dysplasia was associated with presence of H. pylori infection (p=0.029 and p<0.001 respectively).

    CONCLUSION: Even in a setting of low prevalence of H. pylori, intestinal metaplasia and dysplasia were significantly associated with H. pylori infection. The frequency of intestinal metaplasia and dysplasia was similar different between biopsies with atrophic gastritis and non-atrophic gastritis.

  5. Fulltext Epidemiology of Helicobacter pylori infection in Malaysia--observations in a multiracial Asian population
    Goh KL
    Med J Malaysia, 2009 Sep;64(3):187-92.
    PMID: 20527265
    Observations of racial differences in the prevalence of Helicobacter pylori in Malaysia have been intriguing. The Indians and Chinese consistently have a higher prevalence compared to the Malays. The racial cohort theory has been proposed to explain these differences where transmission and perpetuation of infection takes place within a racial group rather than between races, races being separate owing to the low rate of interracial marriages. Studies have demonstrated distinctive bacterial strains between races. Phylogenetic studies have shown that H. pylori isolates amongst Chinese and Indians are distinctive while Malays have Indian and other strains suggesting a more recent acquisition of the bacterium from Indians. H. pylori is recognized as the major causative factor in peptic ulcer disease and gastric cancer. Despite the high prevalence of H. pylori, Indians have a relatively low prevalence of peptic ulcer disease and a low incidence of gastric cancer. This paradox with regards to gastric cancer has been termed the "Indian enigma". Bacterial strain differences between races may be putative but this observation may also indicate gastroprotective environmental factors or a lower genetic susceptibility to develop cancer in the Indians.

  6. Orthosiphon stamineus leaf extract protects against ethanol-induced gastropathy in rats
    Yam MF, Ang LF, Salman IM, Ameer OZ, Lim V, Ong LM, et al.
    J Med Food, 2009 Oct;12(5):1089-97.
    PMID: 19857074 DOI: 10.1089/jmf.2008.0005
    Orthosiphon stamineus Benth., which is used as a gastroprotective herbal remedy in Malaysia, was assessed for its anti-ulcerogenic activity against ethanol-induced ulcers in rats. Fifty percent methanol was used to extract the oven-dried O. stamineus leaves. The extract was then lyophilized with a rotary evaporator and freeze-dried. Oral administration of O. stamineus methanolic extract (OSME) (125, 250, 500, and 1,000 mg/kg) was found to significantly decrease the ulcer index (P < .01, P < .001, P < .001, and P < .001, respectively). Histological study of a section of the rat stomach also showed a marked improvement in the gastric mucosal damage in groups receiving OSME. In order to further investigate the gastroprotective mechanism of OSME, mucus secretion and lipid peroxidation level were estimated in vitro and ex vivo. OSME exhibited dose-dependent stimulation of mucus secretion (r = 0.718, P < .001) and inhibition of lipid peroxidation in rat gastric mucosal homogenates (both in vitro [r = 0.819, P < .05] and ex vivo [r = 0.981, P < .05]). It was concluded that the gastroprotective mechanism of OSME was partly due to its ability to inhibit lipid peroxidation and stimulate gastric mucus secretion.

    PMID: 19338650 DOI: 10.1186/1757-4749-1-5
    The putative H. pylori pathogenicity-associated factor dupA has been associated with IL-8 induction in vitro, and duodenal ulcer (DU) and gastric cancer (GC) development in certain populations, but this association is inconsistent between studies. We aimed to investigate dupA prevalence in clinical isolates from Sweden, Australia and from ethnic Chinese, Indians and Malays resident in Malaysia and Singapore and to examine the association with DU and GC. In addition we investigated the sequence diversity between isolates from these diverse groups and compared the level of IL-8 secretion in isolates possessing and lacking dupA.

    Inflammatory pseudotumour (IPT) is a rare benign solid tumor in adults and children. The prevalence, etiology and pathogenesis of this condition are still uncertain. Despite the use of modern laboratory techniques and imaging, it is often difficult to make the diagnosis of IPT. Besides, occasionally the nonspecific morphological appearance and clinical presentation of the mass may mimic other more common primary or secondary neoplasms. IPT is commonly encountered in the lung and mediastinum. Other sites include abdomen (liver, pancreas, stomach, omentum), retroperitoneum, pelvis (bladder) and extremities in children. We report a rare case of gastric inflammatory pseudotumour in a 65-year-old female patient. Clinical presentations and its management along with review of literatures are presented.

  10. Fulltext Laparoscopic staging in gastric cancer: An essential step in its management
    Mahadevan D, Sudirman A, Kandasami P, Ramesh G
    J Minim Access Surg, 2010 Oct;6(4):111-3.
    PMID: 21120068 DOI: 10.4103/0972-9941.72597
    AIM: The role of laparoscopy in staging of gastric cancer is widely accepted; however, in Malaysia its usage has been limited. Patients can be classified as resectable or unresectable, which helps in avoiding an unwanted laparotomy and the morbidities associated with it. The aim of this study was to assess the value of laparoscopy in staging of gastric cancer in comparison with CT scan.
    MATERIALS AND METHODS: Patients with carcinoma of the stomach after a complete preoperative work-up underwent laparoscopy prior to surgical exploration. TNM staging was used to compare laparoscopy with CT, with the histopathological report used as the gold standard.
    RESULTS: Forty cases were included in this study. The sensitivity of laparoscopy for T3 tumours appears to be significant when compared to that of CT. Laparoscopy detected 90.3% of the cases as against the 58% detected with CT. There was not much difference in the N factor. With regard to M factor, the sensitivity was 100% for laparoscopy in comparison with CT.
    CONCLUSIONS: Laparoscopy has been shown to be sensitive in detecting metastasis in gastric cancer in comparison to CT, thus helping in avoiding unwanted laparotomy and thus providing a more systemic approach in managing gastric cancers.

  12. Controversy of proton pump inhibitor and clopidogrel interaction: a review
    Tan HJ
    J Dig Dis, 2010 Dec;11(6):334-42.
    PMID: 21091895 DOI: 10.1111/j.1751-2980.2010.00466.x
    A proton pump inhibitor (PPI) is often co-prescribed with clopidogrel to reduce the gastrointestinal risk of bleeding ulcers in patients following acute coronary syndrome or a stent implant. However, the safety issue of such practice has been scrutinized after some studies reporting an increased incidence of cardiovascular events and mortality, although there have also been contrary research reports. This has lead to a warning statement from the US Food and Drug Administration cautioning the concomitant use of PPI and clopidogrel. This review examines the evidence of PPI as gastroprotective agent, histamine H(2) antagonists as an alternative therapy, the influence of PPI on the antiplatelet effect of clopidogrel, and the controversies of various studies.

    Helicobacter pylori has been implicated as an aetiologic agent for type B chronic gastritis, peptic ulcer and gastric cancer. It is considered the most common bacterial infection in the world with approximately 50% of the population being infected. The majority of infected individuals are asymptomatic, with some developing gastritis only. However, chronic infection with H. pylori without antibiotic treatment predisposes infected individuals to the development of gastric cancer. The aim of this study is to determine active H. pylori infection among patients with symptoms of dyspepsia using three combinations of diagnostic methods. In this report, we studied 1,376 consecutive patients who underwent upper gastrointestinal endoscopy at Universiti Kebangsaan Malaysia Medical Center (UKMMC) for dyspepsia from the period January 1999 to December 2002. The classification of patient’s diagnosis was assessed by endoscopic and histological examination. The H. pylori status was determined by rapid urease test, histological examination or H. pylori culture. Presence of H. pylori infection was confirmed in 30.8% of patients with dyspepsia. H. pylori infection was more prevalent in older patients and in males compared to females. Patients with severe gastroduodenal diseases were more commonly infected with H. pylori. There was a significant difference in H. pylori prevalence among the different ethnic groups. Indians had the highest infection rate (45.4%), followed by Chinese (36.8%) and the lowest were seen in Malays (18.3%). This finding on determination of active H. pylori infection among patients with dyspepsia is consistent with serological studies that showed racial differences in H. pylori prevalence. However, the pattern of H. pylori infection does not reflect the prevalence of severe gastroduodenal diseases among different ethnic groups.

    Haemorrhage arising from gastric arteriovenous malformation (AVM) is rare and normally occurs in the elderly. Bleeding gastric AVM presenting in the younger age group is even rarer. We report a case of a 14 year old boy who presented with recurrent episodes of haematemesis. He subsequently underwent a proximal gastrectomy and the histological examination confirmed a gastric AVM. After reviewing the literature we believe this is the youngest ever reported case of bleeding gastric AVM reported in English literature.

    PMID: 21443757 DOI: 10.1111/j.1439-0264.2010.01058.x
    The cranial chamber (proventriculus) and caudal chamber (ventriculus) of the stomach of the Red jungle fowl (Gallus gallus spadiceus) were examined by means of light microscopy. Both chambers presented folds of the tunica mucosa lined by a simple prismatic epithelium that was positive for neutral mucin. Simple tubular glands occupied the lamina propria of both chambers; in the ventriculus of older birds, they showed a coiled base. These ventricular glands were lined by simple cuboidal cells represented by the chief cells and a few large basal cells. The luminal and tubular koilin rodlets and folds of the ventriculus were positive to periodic acid Schiff (PAS) stain. The proventricular glands were situated between the inner and outer layers of the lamina muscularis mucosae. Cells lining the tubulo-alveolar units of the proventricular glands showed a dentate appearance. Vacuoles were not observed, and the cells were negative for Alcian-PAS stain. The tunica submucosa was very thin in the proventricular wall. In the ventriculus, it was not separated from the lamina propria owing to the absence of any lamina muscularis mucosae. The tunica muscularis of the proventriculus was formed by a thick inner layer of circular smooth muscle fibres and a thin outer layer of longitudinal fibres. In addition to these layers, oblique muscle fibres formed the most internal layer of the tunica muscularis in the ventriculus.

    Antioxidant and gastroprotective activities of aqueous and ethanolic extract of Andrographis paniculata leaves in rats have been reported. Sprague Dawley rats, 6 per group were used and rats in groups 1 to 6 were pretreated with (0.25% w/v) carboxymethyl cellulose (negative control, 5 ml/kg), 20 mg/kg omeprazole (positive control), (250 mg/kg and 500 mg/kg) of aqueous leaf extracts (APLAE) and (250 and 500 mg/kg) of ethanol leaf extracts (APLEE) respectively. Animals were orally administered with 95% ethanol (5 ml/kg) 60 min after their pretreatments. Rats were sacrificed 1 h after treatment and gastric contents were collected to measure pH and mucous weight. Stomach was analyzed for gross and histological changes. Ulcer control group showed extensive lesions of gastric mucosal layer, whereas rats pretreated with omeprazole, 250 and 500 mg/kg of APLAE showed significant and dose dependent reduction in gastric lesions with increased pH and mucus content of stomach. Rats pretreated with 250 or 500 mg/kg of APLEE showed significantly better inhibition of gastric mucosal lesions. Further, the in vitro antioxidant studies using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay showed that ethanol extracts have superior free radical scavenging activity with IC50 value = 10.9 than aqueous extracts with IC50 value = 24.65. Results of this study showed that pretreatment with ethonolic extract of A. paniculata ethanolic provided significant protection against gastric ulcer by regulating of pH, mucous production and antioxidant property.
