Fulltext Inflammatory Bowel Disease-related Colorectal Cancer in the Asia-Pacific Region: Past, Present, and Future

Zhiqin W, Palaniappan S, Raja Ali RA

Intest Res, 2014 Jul;12(3):194-204.
PMID: 25349593 DOI: 10.5217/ir.2014.12.3.194

Patients with inflammatory bowel disease (IBD) are at an increased risk of developing colorectal cancer (CRC), and key contributing factors include chronic colonic inflammation and the extent and duration of disease. This increase in risk is more likely to result from chronic inflammation of the colonic mucosa than from any clearly defined genetic predisposition. However, globally, the true magnitude of this risk is debatable, since results from different studies are heterogeneous in terms of geographical and methodological variables. The prevalence of IBD-related CRC in the Asia-Pacific region ranges from 0.3% to 1.8% and a recent study found that the cumulative incidence of IBD-related CRC is comparable to that in Western countries. However, the CRC mortality rate in the Asia-Pacific region is on the rise compared with that in Western countries, and a few Asian countries show particularly rapid upward trends in CRC incidence. Although our understanding of the molecular and clinical basis for IBD-related CRC has improved substantially, our means of prevention, endoscopic surveillance, chemoprevention, and prophylactic surgery remain modest at best. Furthermore, published data on IBD-related CRC in the Asia-Pacific region is lacking, and this review addresses many aspects including epidemiology, natural history, etiopathogenesis, morphology, and biological behaviors of IBD-related CRC and sporadic CRC in the Asia-Pacific region. In this review, we will also discuss the risk factors for CRC in IBD patients, endoscopic technology screening, and surveillance programs and management strategies for IBD-related CRC.

Fulltext A novel technique for the management of blandin-nuhn mucocele: a case report

Kumaresan R, Karthikeyan P, Mohammed F, Thapasum Fairozekhan A

Int J Clin Pediatr Dent, 2013 Sep;6(3):201-4.
PMID: 25206223 DOI: 10.5005/jp-journals-10005-1219

Mucocele, a common benign cystic lesion of minor salivary gland and associated ducts develops following extravasation or retention of mucous material in the subepithelial tissue. Occurrence of mucocele of tongue is considered less frequent when compared to a higher incidence of mucocele in the lower lip of young patients. Different modalities of treatment, such as conventional surgical excision followed by newer techniques like cryosurgery, electrocautery have been proposed to completely remove the lesion and reduce the chances of recurrence. Herewith, we report a novel treatment technique using alginate impression material to aid in complete excision of mucocele of glands of Blandin-Nuhn.

Fulltext Nature and pattern of cricket injuries: the Asian Cricket Council Under-19, Elite Cup, 2013

Das NS, Usman J, Choudhury D, Abu Osman NA

PLoS One, 2014;9(6):e100028.
PMID: 24927127 DOI: 10.1371/journal.pone.0100028

Cricket has over the years gained much popularity in Asia, thus the number of cricket players has also grown in tandem. However, cricket players are not as fortunate as other athletes as they do not always have a standard cricket infrastructure to practice; therefore, the injury prevalence is expected to be high. Unfortunately, very few studies have been conducted to investigate the nature and pattern of cricket injuries prevalent to cricketers in this region. Therefore, a prospective cohort injury surveillance study was conducted during the Asian Cricket Council (ACC) Under-19 Elite Cup held in June 2013 in order to gather more data on the type of injuries sustained by cricket players. Overall, 31 injuries occurred to 28 players throughout the tournament, of which 7 injuries happened during practice sessions. The overall injury incidence rate (IIR) was 292.0 per 10,000 player hours (95% CI 176.9-407.1) and 10.4 per 10,000 balls faced and 2.6 per 1000 overs bowled delivered during batting and bowling, respectively. Injuries to the lower limb (IIR: 146; 95% CI 1.8-98.2) were the most frequent, followed by injuries to the upper limb (97.3;95% CI 30.2-164.5) and to the trunk and back (IIR: 36.5;95% CI 0.0-77.7). Sprain/strains (IIR 109.5;95% CI 38.4-180.7) to muscle/tendon and joint/ligament were the most commonly reported nature of injury. This is the first study investigating injury incidence among the players of the ACC. It provides an overview of injuries sustained by elite players' under-19 years of age from 10 Asian countries. The overall IIR is similar to earlier studies conducted in well-established cricket playing nations.

Temporal and spatial mapping of hand, foot and mouth disease in Sarawak, Malaysia

Sham NM, Krishnarajah I, Ibrahim NA, Lye MS

Geospat Health, 2014 May;8(2):503-7.
PMID: 24893027

Hand, foot and mouth disease (HFMD) is endemic in Sarawak, Malaysia. In this study, a geographical information system (GIS) was used to investigate the relationship between the reported HFMD cases and the spatial patterns in 11 districts of Sarawak from 2006 to 2012. Within this 7-years period, the highest number of reported HFMD cases occurred in 2006, followed by 2012, 2008, 2009, 2007, 2010 and 2011, in descending order. However, while there was no significant distribution pattern or clustering in the first part of the study period (2006 to 2011) based on Moran's I statistic, spatial autocorrelation (P = 0.068) was observed in 2012.

MARK's Quadrant scoring system: a symptom-based targeted screening tool for gastric cancer

Tata MD, Gurunathan R, Palayan K

Ann Gastroenterol, 2014;27(1):34-41.
PMID: 24714557

BACKGROUND: Gastric cancer is notably one of the leading causes of cancer-related death in the world. In Malaysia, these patients present in the advanced stage, thus narrowing the treatment options and making the surgery nearly impossible for successful curative resection. Failure to identify high-risk patients and delay in diagnostic endoscope procedure contributed to the delay in diagnosis. The aim of the study was to develop and validate a scoring system (MARK's Quadrant) which can identify symptomatic patients who are at risk for gastric cancer.
METHODS: A 3-phase approach was undertaken: Phase 1: development of the weighted scoring system; Phase 2: estimating positive predicting value of MARK's Quadrant; and Phase 3: a) testing the validity of MARK's Quadrant in an open-access endoscope system; and b) comparing its usefulness compared to conventional referral system.
RESULTS: In phases 1 and 2, MARK's Quadrant with weighted symptoms was developed. The sensitivity of MARK's Quadrant is 88% and the specificity is 45.5% to detect cancerous and precancerous lesions of gastric. This was confirmed by the prospective data from phase 3 of this study where the diagnostic yield of MARK's Quadrant to detect any pathological lesion was 95.2%. This score has a high accuracy efficiency of 75%, hence comparing to routine referral system it has an odds ratio (95%CI) of 10.98 (4.63-26.00), 6.71 (4.46-10.09) and 0.95 (0.06-0.15) (P<0.001 respectively) for cancer, precancerous lesion and benign lesion diagnosis respectively.
CONCLUSION: MARK's Quadrant is a useful tool to detect early gastric cancer among symptomatic patients in a low incidence region.

Fulltext Fish in throat: An unusual foreign body

Tang ML, Ching LS, Brito-Mutunayagam S, Revadi G

Med J Malaysia, 2013 Dec;68(6):469-70.
PMID: 24632915 MyJurnal

A 19 year-old man was presented to us in a state of respiratory distress with history of alleged accidentally swallowed the live fish. Flexible nasopharyngolaryngoscope showed a big live fish impacted in the laryngopharynx. Attempts to remove the fish orally were futile as the fish was impacted. We resorted to tracheostomy under local anaesthesia, followed by direct laryngoscopy and removal of the fish under general anaesthesia. The literature review of such rare incidence and approach to such case are discussed.

Fulltext Monsoon and primary acute angle closure in Malaysia

Ch'ng TW, Mosavi SA, Noor Azimah AA, Azlan NZ, Azhany Y, Liza-Sharmini AT

Med J Malaysia, 2013 Oct;68(5):410-4.
PMID: 24632871 MyJurnal

INTRODUCTION: Acute angle closure (AAC) without prompt treatment may lead to optic neuropathy. Environmental factor such as climate change may precipitate pupillary block, the possible mechanism of AAC.

OBJECTIVE: To determine the association of northeast monsoon and incidence of AAC in Malaysia.

MATERIALS AND METHODS: A retrospective study was conducted on AAC patients admitted to two main tertiary hospitals in Kelantan, Malaysia between January 2001 and December 2011. The cumulative number of rainy day, amount of rain, mean cloud cover and 24 hours mean humidity at the estimated day of attack were obtained from the Department of Meteorology, Malaysia.

RESULTS: A total 73 cases of AAC were admitted with mean duration of 4.1SD 2.0 days. More than half have previous history of possibility of AAC. There was higher incidence of AAC during the northeast monsoon (October to March). There was also significant correlation of number of rainy day (r=0.718, p<0.001), amount of rain (r=0.587, p<0.001), cloud cover (r=0.637, p<0.001), mean daily global radiation (r=- 0.596, P<0.001), 24 hours mean temperature (r=-0.298, p=0.015) and 24 hours mean humidity (r=0.508, p<0.001) with cumulative number of admission for AAC for 12 calendar months.

CONCLUSION: Higher incidence of AAC during northeast monsoon suggested the effect of climate as the potential risk factor. Prompt treatment to arrest pupillary block and reduction of the intraocular pressure is important to prevent potential glaucomatous damage. Public awareness of AAC and accessibility to treatment should be part of preparation to face the effect of northeast monsoon.

Fulltext Encephalitis followed by optic neuritis: a case report and review of literature

Hasan S, B Basri H, P Hin L, Stanslas J

Pak J Med Sci, 2013 May;29(3):859-62.
PMID: 24353644

Encephalitis has been included in the causes of optic neuritis, but post encephalitic optic neuritis has been rarely reported. Majority of the cases of optic neuritis are either idiopathic or associated with multiple sclerosis, especially in western countries. This is very important in the Asian population where the incidence and prevalence of multiple sclerosis is not as high as in the Western countries. Although post infectious optic neuritis is more common in children, it can also be found in adults and is usually seen one to three weeks after a symptomatic infective prodrome. Here, we present a case of a 48 year-old-male who developed optic neuritis following viral encephalitis. His first presentation was with severe headache of two weeks duration. Viral encephalitis was diagnosed and treated. The patient presented again three weeks later with right eye pain and other features typical of optic neuritis. Corticosteroid therapy facilitated prompt recovery. Optic neuritis is an uncommon manifestation of encephalitis. It is important that both doctors and patients remain aware of post infectious cause of optic neuritis, which would enable a timely diagnosis and treatment of this reversible cause of vision loss.

Fulltext Trends of dengue infections in Malaysia, 2000-2010

Mia MS, Begum RA, Er AC, Abidin RD, Pereira JJ

Asian Pac J Trop Med, 2013 Jun;6(6):462-6.
PMID: 23711707 DOI: 10.1016/S1995-7645(13)60075-9

OBJECTIVE: To analyze trends of dengue incidences and deaths in Malaysia from 2000 to 2010 as well as the predominant dengue virus serotypes during the last decade.
METHODS: We used the national data on annual reported cases, deaths, incidence rate, mortality rate, and case fatality rate of dengue fever (DF) and dengue hemorrhagic fever (DHF) as well as dengue virus serotypes prevalent in Malaysia during the last decade. Trend/ regression lines were fitted to investigate the trend of dengue incidences and deaths due to the disease for a 11-year period (2000-2010). For the distribution of national incidence rate, mortality rate, and case fatality rate of DF and DHF, descriptive statistics using mean and 95% confidence intervals (CI 39) for means, and range were applied.
RESULTS: The number of dengue cases and number of deaths have increased, on average, by 14% and 8% per year respectively. The average annual incidence rate of DF per 100 000 populations was higher as compared to that of DHF. Conversely, the yearly mean mortality rate of DHF per 100 000 populations was greater than that of DF. The simultaneous circulation of all four dengue serotypes has been found in Malaysia. But a particular dengue virus serotype predominates for at least two years before it becomes replaced by another serotype.
CONCLUSIONS: The dengue situation in Malaysia has worsened with an increasing number of reported cases and deaths during the last decade. The increasing trend of dengue highlights the need for a more systematic surveillance and reporting of the disease.

Iftikhar A, Naseeb AK, Khwaja A, Mati H, Karim K, Hameeda N

Med J Malaysia, 2011 Oct;66(4):322-5.
PMID: 22299551

The incidence of thyroid cancer is increasing in several countries. The main objective of this retrospective study was to find and describe province-specific estimates of incidence in males and females by age groups for differentiated thyroid cancer (DTC). This study reports on 87 cases of DTC from Baluchistan province of Pakistan treated with post operative radioiodine at the Center for Nuclear Medicine and Radiotherapy (CENAR) Quetta from January 2003 to December 2009. The patient data has been collected from CENAR Quetta. Patients with DTC were confirmed by clinical examination, thyroid scintigraphy (Thyroid scan), blood tests (T3, T4, TSH) and histopathalogy tests and then treated with radioiodine. The Median age of the patients was 35.5 years (Range 12-70 years). The final histological diagnosis was papillary carcinoma in 71 (81.6 %) cases, follicular carcinoma in 6 (6.9%) cases while 10 (11.5%) cases presented with mixed papillary and follicular carcinoma. About 53 % cases were found in females with age 21-40 years. No strike predominance was observed in any age group for males. Four patients presented with recurrence while six patients showed metastasis in cervical lymph nodes. The small annual incidence did not follow any definite pattern. DTC has a small incidence in Baluchistan due to lack of education and health care facilities. The incidence of DTC is higher in females when compared with males as per this study. This preliminary study will provide an insight to incidence of DTC, its treatment facilities and future planning strategies in Baluchistan, Pakistan.

Fulltext Unilateral foul smelly nasal discharge in an adult

Irfan M, Hasme Zam H, Mohd Khairi M

Malays Fam Physician, 2012;7(1):28-30.
PMID: 25606242 MyJurnal

The incidence of rhinolith is by far very low compared to the nasal foreign bodies, especially in adult. Foreign body (FB) in the nostril will lead to unilateral nasal symptom which can start with nasal obstruction or discomfort. In younger children, they may miss to report the problem to the parents but, later on, the FB will manifest itself with unilateral nasal discharge, which at most of the time fouls smells. We report a case of a healthy adult female who presented with unilateral foul smelly nasal discharge which later was diagnosed as rhinolith, with rubber-tip pencil eraser as the nidus of calcification.

Neonatal Tetanus is a severe disease with high fatality. It should no longer be present in a country with the development status of Malaysia. However, sporadic cases still occur and the disease has not been eradicated. This editorial summarises the disease pattern, incidence and suggests reasons for the continued persistence of the condition locally.

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.

Fulltext Spectrum of thyroid lesions in hospital Universiti Sains Malaysia over 11years and a review of thyroid cancers in Malaysia

Othman NH, Omar E, Naing NN

Asian Pac J Cancer Prev, 2009;10(1):87-90.
PMID: 19469631

INTRODUCTION: Endemic goitre is a major concern in many nations including Malaysia. Seven states in the country have been identified by Ministry of Health of Malaysia to have high incidence of goitre and one of these is Kelantan.

METHODS: This is a retrospective study over an 11-year period from 1994 to 2004 on all thyroid specimens submitted to the Pathology Department, Hospital Universiti Sains Malaysia (HUSM), in Kelantan. Epidemiological data were retrieved from the patients' records and pathology findings from the pathology reports.

RESULTS: During this period, Department of Pathology HUSM received a total of 1,486 thyroid specimens. The female to male ratio was 6:1 and the median age was 40.0 years. The duration of goitre ranged from one to 15 years. Histopathological examination showed 71.9 percent were non-neoplastic and 28.1 percent neoplastic lesions. The hospital-based incidence of nodular hyperplasia was 9.9 per 100,000 admitted patients per year. The hospital-based incidence of all types of malignant thyroid cancers was 3.5 per 100,000. The most common malignancy was papillary carcinoma 76.6 percent. The majority of the cancers (59.5 percent) occurred in a background of nodular hyperplasia. Thyroid cancers made up 4.9 percent of all cancers seen in HUSM.

CONCLUSION: This study suggests that malignant thyroid lesions arising from multi-nodular goitre are high in a population living in an iodine-deficiency area.

Overview of the disease burden of invasive pneumococcal disease in Asia

Bravo LC, Asian Strategic Alliance for Pneumococcal Disease Prevention (ASAP) Working Group

Vaccine, 2009 Dec 9;27(52):7282-91.
PMID: 19393708 DOI: 10.1016/j.vaccine.2009.04.046

This paper represents a collaborative effort by the Asian Strategic Alliance for Pneumococcal Disease Prevention (ASAP) Working Group to collate data on the disease burden due to invasive pneumococcal disease (IPD) in participating Asian countries and territories; namely, Hong Kong, India, Indonesia, Korea, Macau, Malaysia, Pakistan, the Philippines, Singapore, Sri Lanka, Taiwan and Thailand. A review of both published and unpublished data revealed that the incidence of IPD in some countries is well documented by way of large, long-duration studies, while in other countries, much of the available data have been extrapolated from international studies or have come from small population studies of limited geographical coverage. This paper confirms that data regarding the incidence of IPD in Asia are grossly lacking and reinforces the need for urgent and more substantial studies.

Breast cancer in Asia

Yip CH

Methods Mol Biol, 2009;471:51-64.
PMID: 19109774 DOI: 10.1007/978-1-59745-416-2_3

Breast cancer is the commonest cancer in most countries in Asia. The incidence rates remain low, although increasing at a more rapid rate than in western countries, due to changes in the lifestyle and diet. There are many differences between breast cancer in Asia compared with western countries. The mean age at onset is younger than in the west, and unlike the west, the age-specific incidence decreases after the age of 50 years. Because there is no population-based breast cancer screening program in the majority of Asian countries, the majority of patients present with advanced disease. There is a higher proportion of hormone receptor-negative patients, and some evidence that the cancers in Asia are of a higher grade. Most of the Asian countries are low- and middle-income countries, where access to effective care is limited. Because of the late detection and inadequate access to care, survival of women with breast cancer in Asia is lower than in western countries. Improving breast health in most of the Asian countries remains a challenge that may be overcome with collaboration from multiple sectors, both public and private.

Changing trends in gastrointestinal disease in the Asia-Pacific region

Goh KL

J Dig Dis, 2007 Nov;8(4):179-85.
PMID: 17970873

The new millennium has seen distinct changes in the pattern of gastrointestinal disease in the Asia-Pacific region. These changes are important as more than half of the world's population come from the region and therefore impact significantly on the global disease burden. The highest incidence of gastric cancer (GCA) has been reported from Asia and GCA remains a very important cancer. However time-trend studies have shown a decrease in GCA incidence in several countries in Asia. A rise in cardio-esophageal cancers as seen in the West has not been reported. On the other hand, colorectal cancer has been steadily increasing in Asia with age-standardized incidence rates of some countries approaching that of the West. The pattern of acid-related diseases has also changed. Gastroesophageal reflux disease is a fast emerging disease with an increasing prevalence of reflux esophagitis and reflux symptoms. The prevalence of peptic ulcer disease has at the same time declined in step with a decrease in H. pylori infection. Many of the changes taking place mirror the Western experience of several decades ago. Astute observation of the epidemiology of emerging diseases combined with good scientific work will allow a clearer understanding of the key processes underlying these changes. With rapid modernization, lifestyle changes have been blamed for an increase in several diseases including gastroesophageal reflux disease, nonalcoholic fatty liver disease and colorectal cancer. A worrying trend has been the increase in obesity among Asians, which has been associated with an increase in metabolic diseases and various gastrointestinal cancers. Conversely, an improvement in living conditions has been closely linked to the decrease in GCA and H. pylori prevalence.

PMID: 21614253 MyJurnal DOI: 10.2349/biij.2.3.e7

Hepatitis B virus (HBV) is one of the most well recognised human carcinogens. Since its discovery about 40 years ago, HBV has been studied extensively. This article summarises the evidence derived from various studies including epidemiological, animal model, histopathology studies and molecular genetics studies leading to the establishment of HBV as the main aetiological agent for hepatocellular carcinoma (HCC). The reduction in the incidence of childhood HCC due to mass hepatitis B vaccination in Taiwan is a dramatic demonstration of the critical aetiological role of hepatitis B in HCC. Thus it is essential for interventionalists to understand the epidemiological and pathogenesis of HCC to ensure optimal patient care.
