This study was undertaken to clinically estimate the prevalence of diabetic peripheral neuropathy amongst patients attending an outpatient clinic and to evaluate their risk factors for developing peripheral neuropathy. It was a cross-sectional study of 134 diabetes mellitus patients who attended the Primary Care Clinic, University Hospital, Kuala Lumpur. The patients were interviewed for their demographic data, past and present medical/surgical history, social history, personal habits and symptoms of peripheral neuropathy. Foot examination and clinical neurological tests were conducted and the presence of peripheral neuropathy was assessed. The main outcome measures were the Neuropathy Symptom Score and the Neuropathy Disability Score. The prevalence of diabetic peripheral neuropathy was found to be 50.7%. Peripheral neuropathy was related to the age of the patient and the duration of diabetes but did not seem to be significantly related to diabetic control. To conclude, there was a high prevalence of peripheral neuropathy amongst the diabetics in this study. These patients developed peripheral neuropathy at a younger age and shorter duration of diabetes compared to a similar study that was done in the UK.

The cornerstone of asthma management is achieving adequate symptom control and patient education. We studied in our local population of asthmatic patients how well their symptoms were controlled with currently prescribed treatment and their insight into the disease and its management. Over a 6-month period, 93 asthmatics recruited from two local government health clinics and a state hospital were interviewed using a standard questionnaire. Patients were classified into 4 groups based on the treatment they were on according to Global Initiative for Asthma (GINA) treatment guidelines. The number of patients in Step 1 (rescue medication alone), Step 2 (1 controller medication), Step 3 (2 controller medications) and Step 4 (at least 3 controller medications) were 8, 39, 34 and 12, respectively. Except for day symptoms in Step 1 group, fewer than 50% achieved minimum day or night symptoms and no restriction of daily activities. Questions on patient insight were only available for 50 patients. Weather change (74%), air pollution (66%) and physical stress (46%) were the three highest ranked common asthma triggers. More than half correctly recognized the important symptoms of a serious asthma attack but fewer than 15% were familiar with the peak flow meter and its use or with the asthma self-management plan. Most patients perceived that their treatment had helped reduce disease severity and exacerbations. We conclude that symptom control and some aspect of patient education are still lacking in our local asthmatics.

A study was conducted to determine the clinical factors that affect the quality of life in adult asthmatics. As part of their routine follow-up visit, 399 patients completed the SF-36 quality of life questionnaire, had peak expiratory flow rate readings (PEFR) taken and were interviewed to determine current symptom severity. The grade of severity of asthma was verified by the consultant physician in-charge. The mean age of the patients was 41.8 years and 31.8% of the patients were men. Most of the patients were Malay (64.7%), 89% had at least secondary level education and the mean duration of asthma was 17.6 years. The majority of patients had moderate or severe disease (43.6% and 55.9% respectively). For asthmatics with moderate or severe symptoms of chest tightness and/or shortness of breath, all domains of SF-36 scored significantly lower than those with mild symptoms, with the exception of the domain bodily pain. Patients with moderate/severe cough recorded significantly lower scores than those with mild cough for all domains except for bodily pain and social functioning. Only the physical functioning, role physical, general health and role emotional scores were significantly worse in those with a consultant grade of severe asthma compared to those with mild/moderate asthma. Patients with PEFR < 80% predicted had lower scores for the domains physical functioning, role physical and general health than those with PEFR > or = 80% predicted, but the scores for the other domains were similar in both groups. Quality of life is significantly impaired in adult asthmatics with current respiratory symptoms. However, consultant grade of severity of asthma and PEFR readings do not affect quality of life scores as much.

In Malaysia, there is limited information on the mortality and morbidity after an acute stroke in hospitalised patients. The objective of the study was to identify the type, time of onset, and frequency of medical and neurological complications following an acute ischaemic stroke. Consecutive patients with acute ischaemic stroke who were admitted to Hospital Universiti Kebangsaan Malaysia from June 2000 to January 2001 were observed. The complication rate was 20.9%. The most common individual complication was pneumonia (12.3%), followed by septicaemia (11.0%), urinary tract infection (4.3%), and upper gastrointestinal haemorrhage (3.7%). The overall mean length of stay was 7.48 days. The independent risk factors for complications were diabetes mellitus (OR 2.87; 95%CI 1.06 to 7.78), middle cerebral artery (MCA) infarcts (OR 10.0; 95%CI 4.1 to 24.3), and Glasgow coma score (GCS) less than 9(OR 3.8; 95%CI 1.03 to 14.3). Infection was the commonest complication observed. Patients with diabetes mellitus, poor GCS and large MCA infarcts had a higher risk of developing complications.
A retrospective study was conducted at the Hospital Sultanah Aminah Johor Bahru to determine the outcome of trabeculectomy surgeries over a period of 4 years. One hundred and two eyes were followed up to a maximum of 63 months (mean 34.2 months). The 2-year survival rates for plain trabeculectomies, 5-Fluorouracil augmented trabeculectomies and Mitomycin-C augmented trabeculectomies were 52.9%, 27.3% and 60.5% respectively. The commonest complications noted were cataract formation (25%) and hyphaema (11%). Mitomycin-C induced complications were rarely seen. At last follow-up, 54% of eyes had intraocular pressures below 21 mmHg without medication, while 34% of eyes had intraocular pressures below 21 mmHg with medication. Vitreous at the trabeculectomy site was a statistically significant predictor of operative failure.
Two thousand five hundred and eight subjects from the state of Kelantan in North-East Peninsular Malaysia were included in this study to determine the prevalence of hypertension and their association with cardiovascular risk factors. The overall prevalence of hypertension was 13.9%. There was no difference in the prevalence of hypertension between the males and females. The prevalence increased with age--the highest being in those above 70-years old. Subjects with hypertension also had a higher prevalence of diabetes mellitus (19.0%), obesity (39.4%) and hypercholesterolaemia (70.7%) than non-hypertensive subjects. Of the hypertensive subjects, 83.3% had 1 other risk factor for cardiovascular disease, 66.7% had 2 other risk factors and 16.7% had more than 2 risk factors. Other than age, body mass index, plasma glucose, total cholesterol and LDL-cholesterol, hypertensive subjects also had a higher mean serum urea, creatinine, uric acid and triglyceride than non-hypertensive subjects. In conclusion, hypertension is a common disease in this area and is associated with multiple risk factors for cardiovascular disease. The prevalence is likely to increase in the near future with increasing affluence and becoming a major health problem.
We studied the admission criteria and first 24-hour management of 62 asthmatic patients admitted from Accident and Emergency (A&E) department of a state hospital. Data was collected prospectively over a 6-month period from the doctors' medical records with reference to recommendations of the Malaysian Thoracic Society (MTS) on management of acute asthma. Peak Expiratory Flow Rate (PEFR) records were present in only 14.5% of the A&E notes and 54.8% of the ward notes. Most of these readings were below 75% of predicted normal values. Over half of the patients had records on ability to speak full sentences, and respiratory and pulse rates. Based on other records on criteria for life-threatening features (including arterial blood gases), 42% of patients studied had life threatening asthma exacerbations. Most received appropriate treatment as recommended by the MTS. We conclude that while most patients were admitted and treated appropriately, medical documentation regarding acute asthma assessment were inadequate in some.

Between 1st January 1999 and 31st December 2000, 452 foreign nationals were treated at the Department of Ophthalmology, Hospital Sultanah Aminah, Johor Bahru. Eighty-five percent were male. The peak age range was from 21 to 30 years old. The patients were predominantly Indonesians (61%). A history of trauma was present in 63% of patients. Eight percent of eyes had severe visual impairment. Six patients (1.3%) were blind by WHO standards. Traumatic eye conditions, inflammatory/allergic eye conditions and degenerative eye conditions comprised 66%, 13% and 10% respectively of ocular pathology seen. The commonest ocular findings were corneal foreign body, corneal abrasion and subconjunctival haemorrhage.
The cause and effect relationship between acute pancreatitis and primary hyperparathyroidism (pHPT) still evokes controversy. Our paper reviews the debate in the medical literature. In this controversy we add a case of a 49-year old non-alcoholic man presenting with recurrent attacks of acute pancreatitis. His raised serum calcium was realized rather late. Eventually, high intact parathyroid hormone levels led to open neck exploration and finding of a solitary parathyroid adenoma. Post-surgery, serum calcium returned to normal and abdominal symptoms disappeared. The case report and the accompanying literature review support our belief, that acute pancreatitis is one of the symptoms of pHPT often caused by a parathyroid adenoma and curable by its excision.
We report two patients, who have used Pneumostat to replace the conventional underwater seal drainage system for recurrent pneumothorax. Both patients had required repeated chest tube insertion for recurrent pneumothorax and needed a longer hospital stay. Both patients were able to be discharged with the Pneumostat device and were reviewed in outpatient clinic. Both patients had optimal clinical improvement and chest X-ray showed no residual pneumothorax.
Chronic hepatitis C manifests with many extrahepatic features including renal involvement. However, less commonly, interferon therapy for chronic hepatitis C can also result in renal involvement and we describe a case when interferon therapy resulted in minimal change glomerulopathy, a form of involvement which, carries a good prognosis. Our patient developed nephrotic syndrome while on interferon therapy and HCV RNA levels were undetectable at that time. The disease showed excellent response to steroid therapy.
A study was done on survival of patients surgically treated for lung cancer from 1995-2001. The average operative rate for 852 patients was 4.8%. In 67 surgically treated patients (54M, 13F), the commonest histological type was squamous cell carcinoma (52.2%) followed by adenocarcinoma (26.9%). The surgical-pathological stage was stage I in 52.2%. Postoperatively, five-year survival was 29%, with a median survival of 27 months. Completeness of resection was the foremost determinant of survival outcome and stage higher than stage I was an adverse prognostic factor. These results indicate that the current outlook for lung cancer patients remains poor.
Seventy patients presented with acute asthma at the emergency department of the University of Malaya Medical Centre, Kuala Lumpur were recruited over a two-week period in July 2001. Fifty-one (73%) patients belonged to the poorly controlled group. Fifty-seven (81%) patients were using inhaled salbutamol but 21 (30%) were still using oral short acting salbutamol. Only 32 (46%) patients used inhaled corticosteroids. In the poorly controlled group, 22 (43.1%) patients were not on regular inhaled corticosteroids, 35 (68.6%) were not receiving "add-on" medication and 18 (35%) did not have regular follow up. The emergency department should implement a protocol for asthma management and follow up to achieve better long term patient care.
Lymphomas, ranked twelve among all cancers world-wide in the 1990s, in which it is more prevalent in males compared to females. A previous study on lymphomas in East Malaysia for a period of 3 years from 1981-1983 showed that the pattern of lymphomas conformed to the general pattern observed in Asia. Current study reviews lymphoma cases from the Department of Pathology, Queen Elizabeth Hospital, Sabah between 1997 and 1999, with the aim of investigating if the spectrum and pattern in Sabah has since changed, a decade later. A total of 91 confirmed lymphoma cases were phenotyped with a panel of antibodies and classified using the new WHO proposed list of lymphoid neoplasms. The 1981-1983 series was reviewed and cases reclassified accordingly for comparison. There are 83 (91.2%) NHL and 8 (8.8%) HL cases in this series, a ratio of NHL to HL of 9:1. Of the 83 cases of NHL, 66 (79.5%) were confirmed B-cell type, 13 (15.7%) T-phenotype, 1(1.2%) null cell type and one case unclassified. Diffuse large B-cell lymphoma is the most prevalent, (65.1%), followed by Burkitt's lymphoma and follicular lymphoma, (10.6%) each. Lymphoma pattern concurs with the previous series from Sabah, with higher prevalence of diffuse large cell lymphoma and lower incidence of follicular lymphoma and HL, as seen elsewhere in Asia. There is an overall increase in the number of cases of NHL in the 1990s. However, the proportion of T-NHL is reduced when compared to the series in the 1980s.
The poor prognosis for patients with nasopharyngeal carcinoma is principally due to its advanced stage at the time of diagnosis. The symptoms and clinical findings at presentation of 56 patients with confirmed nasopharyngeal carcinoma is described and analysed. Recognising the common modes of presentation is essential to diagnose the disease at an early stage.
Scopulariopsis brevicaulis is a soil fungus normally associated with onychomycosis. It causes subcutaneous infection in immunocompromised patients and is rarely isolated from blood. A case of systemic Scopulariopsis brevicaulis infection was reported in a patient with acute myeloid leukemia. The patient developed persistent fever that did not respond to wide spectrum antibiotics and amphotericin B. Scopulariopsis brevicaulis was the only pathogen isolated from blood cultures. The fever subsided with itraconazole and there was no recurrence of fungal infection with prolonged maintenance of oral itraconazole.
Massive postpartum haemorrhage after Cesarean section for placenta previa is a common occurrence. The bleeding is usually from the placental bed at the lower uterine segment. Uterine tamponade has a role in the management of such patients especially when fertility is desired. We describe here a case of massive postpartum haemorrhage, which was managed, with the use of a Sengstaken-Blakemore tube. This allowed us to avoid a hysterectomy for a young primiparous patient.
We retrospectively analyzed all patients presenting with upper gastrointestinal bleeding to Seremban Hospital over a one-year period. A quarter of the oesophagogastro-duodenoscopies (OGD) performed were performed as emergency for upper gastrointestinal tract bleeding. Gastric ulcers and duodenal ulcers were the two most common findings. Our results suggest that there is a male preponderance of 2:1, the Chinese were more likely to be affected and the elderly (> 60 years) were at highest risk.
Comparative surgical audit to monitor quality of care should be performed with a risk-adjusted scoring system rather than using crude morbidity and mortality rates. A validated and widely applied risk adjusted scoring system, P-POSSUM (Portsmouth-Physiological and Operative Severity Score for the enUmeration of Mortality) methodology, was applied to a prospective series of predominantly general surgical patients at the Sarawak General Hospital, Kuching over a six months period. The patients were grouped into four risk groups. The observed mortality rates were not significantly different from predicted rates, showing that the quality of surgical care was at par with typical western series. The simplicity and advantages of this scoring system over other auditing tools are discussed. The P-POSSUM methodology could form the basis of local comparative surgical audit for assessment and maintenance of quality care.
