METHODS: In the present prospective study, 426 consecutive patients underwent colonoscopic examination between March 1997 and January 2000, for a variety of bowel symptoms. The examinations were performed by an experienced endoscopist using a standard colonoscope and methylene blue dye spraying technique. Macroscopically, flat adenomas were defined using the criteria proposed by Sawada.
RESULTS: Twenty-nine adenomas were identified in 12 patients, of which 15 were polypoid and 14 were flat, with no depressed lesions. Eight polypoidal lesions and all the flat adenomas contained mild or moderate areas of epithelial dysplasia. Seven severely dysplastic polyps were identified. One Duke's A polypoidal cancer and two advanced carcinomas were also found. All the severely dysplastic lesions and Duke's A carcinomas were found in polyps greater than 10 mm in mean size. The flat adenomas were all less than 5 mm in size.
CONCLUSIONS: A significant proportion of colonic adenomas in Malaysian patients appear as small flat lesions, which could easily be missed during endoscopy. Increased recognition and treatment of flat adenomas among colonoscopists is warranted.
METHODS: A prospective 6 wk review of all pediatric (< 18 y) attendees to an urban ED was done, with patient age, presenting complaints, diagnoses, time of arrival and disposition recorded.
RESULTS: Complete data were available on 1172 patients, with an age range of 4 d to 18 y (mean +/- SD 6.9 +/- 5.6 y); 43% were aged < or = 4 y. The main presenting complaints were injuries (26.9%), fever (24%) and breathing difficulties (16.6%). The most common diagnosis was minor trauma (24.2%), with soft-tissue injuries predominating (80.6%). The other diagnoses were asthma (12.6%), upper respiratory infections (12.1%), other infections (12.1%) and gastroenteritis (11.8%). Equal proportions of patients were seen throughout the day. 25% of patients were admitted. Young age (< 1 y); presence of past medical history, general practitioner referrals, diagnosis of bronchiolitis and pneumonia were significantly associated with risk of admission.
CONCLUSION: A wide spectrum of paediatric illnesses was seen in the ED, with an overrepresentation of young children. This supports the decision to have either a separate pediatric ED or paediatric residents on the staff. The training curricula should emphasize the management of pediatric trauma, infections and asthma. Alternatively, developing guidelines for the five most common presenting complaints would account for 82% of all attendees and could be directed towards all staff on the ED.
OBJECTIVES: To document the prevalence of CHF in the multiracial population of Malaysia, and to describe the clinical features and management of these patients.
SETTING: Busy city centre general hospital in Kuala Lumpur, Malaysia.
RESULTS: Of 1435 acute medical admissions to Kuala Lumpur General Hospital over the 4-week study period, 97 patients (6.7%) were admitted with the primary diagnosis of CHF. Coronary artery disease was the main aetiology of CHF, accounting for almost half (49.5%) the patients, followed by hypertension (18.6%). However, there were variations in associated aetiological factors between ethnic groups, with diabetes mellitus affecting the majority of Indians-as well as underutilisation of standard drugs for CHF, such as the angiotensin converting enzyme (ACE) inhibitors, which were only used in 43.3%.
CONCLUSION: Amongst acute medical admissions to a single centre in Malaysia the prevalence of CHF was 6.7%. Coronary artery disease was the major aetiological factor in heart failure accounting for almost half the admissions. The under-prescription of ACE inhibitors was similar to other clinical surveys carried out amongst Caucasian populations in the West.
OBJECTIVES: To document the prevalence of atrial fibrillation (AF) in the multiracial population of Malaysia, and to describe the clinical features and management of these patients.
SETTING: Busy city centre general hospital in Kuala Lumpur, Malaysia, over a 1-month period.
SUBJECTS: One-thousand four hundred and thirty-five acute medical admissions, of whom 40 patients (2.8%) had AF.
RESULTS: Of 1435 acute medical admissions to Kuala Lumpur General Hospital over the 4-week study period, 40 had AF (21 male, 19 female; mean age 65 years). Of these, 18 were Malay, 16 Chinese and six Indian. Nineteen patients had previously known AF (seven with paroxysmal AF) and 21 were newly diagnosed cases. The principal associated medical conditions were ischaemic heart disease (42.5%), hypertension (40%) and heart failure (40%). Dyspnoea was the commonest presentation, whilst stroke was the cause of presentation in only two patients. Investigations were under-utilised, with chest X-ray and echocardiography in only 62.5% of patients and thyroid function checked in 15%. Only 16% of those with previously diagnosed AF were on warfarin, with a further three on aspirin. Anticoagulant therapy was started in 13.5% of patients previously not on warfarin, and aspirin in 8%. Records of contraindications to warfarin were unreliable, being identified in only 25%. For those with known AF, 58% were on digoxin. For new onset AF, digoxin was again the most common rate-limiting treatment, initiated in 38%, whilst five patients with new onset AF were commenced on amiodarone. DC cardioversion was not used in any of the patients with new onset AF.
CONCLUSION: Amongst acute medical admissions to a single centre in Malaysia the prevalence of AF was 2.8%. Consistent with previous similar surveys in mainly western (caucasian) populations, standard investigations in this Malaysian cohort were also inadequate and there was underuse of anticoagulation, medication for ventricular rate control and cardioversion to sinus rhythm.
