    In this study 24 patients who had conventional erect lateral X-ray pelvimetry had a CT pelvimetry done after delivery to complete the pelvimetry views. The erect lateral pelvimetry was read independently by a Consultant Radiologist, Consultant Obstetrician and a Medical Officer training in Obstetrics and Gynaecology. Using CT pelvimetry as the 'gold standard' (as the error of measurement was known with the machine used) the 3 readings were compared. There was no statistical difference in the values suggesting that X-ray pelvimetry is comparable to CT pelvimetry. However CT pelvimetry is preferred, if available, because of the lower dose of radiation involved, more comfort for the patient and shorter time in performing the procedure. Measurements done are easily read directly from the CT console.

    Merital is a recently introduced antidepressant agent which is structurally unrelated to the traditional antidepressant agents and which is reported to have minimal side effects. This study aimed to establish the olerance of a single compared to a spaced dose .schedule of Merital. It was found that a single morrung dose of Merital 100 mgs compared to a similar dose of the drug given in two divided doses did not appreciably increase the frequency or severity of side effects.

    A prospective study was carried out on 26,176 Malaysian neonates born in the Maternity Hospital, Kuala Lumpur over a 12-month period to determine the incidence and associated risk factors of brachial plexus injuries. This condition was found in 42/26,176 neonates (1.6 per 1000 livebirths). Multiple logistic regression analysis of affected and control neonates from a nested case-control study showed that increasing birth weights and breech deliveries were the significant risk factors. Our study suggests that to reduce the occurrence of this condition, there is a need for: (i) better assessment of fetal size and maternal pelvimetry to enable earlier diagnosis of cephalo-pelvic disproportion, and (ii) review of the indications and techniques of breech delivery.

    Cardiac complications comprise as much as 50% of perioperative vascular surgical morbidity and mortality. Using the Goldman multifactorial index for evaluating cardiac risk pre-operatively, 53 consecutive patients who underwent abdominal aortic aneurysm surgery were prospectively studied. Forty patients (75.5%) were also evaluated with echocardiography for assessment of left ventricular function. There were 14 (23.7%) peri-operative events, of which nine (17.0%) were acute myocardial infarctions--two of whom died (3.8%). The minor complications included three with hypovolaemic renal failure, and one each with acute respiratory failure and cerebrovascular accident. Patients with Goldman cardiac risk index (CRI) classes III and IV were associated with significantly higher risks of peri-operative complications (p less than 0.001), i.e. 77.8% and 66.7% respectively, compared with class II (22.7%) and class I (nil). Echocardiographic left ventricular shortening fraction (LVFS) of less than 28% helped identify high risk groups in all classes, although its positive predictive value was low (42.3%). Combining LVFS less than 28% with Goldman CRI categories II to IV improved the sensitivity to 91.7% and the positive predictive value to 61.1%. Careful pre-operative assessment using the simple Goldman index and echocardiography is helpful in identifying higher risk patients who would benefit from pre-operative stabilisation and more rigorous perioperative hemodynamic monitoring preferably including intensive care (ICU) management, so as to reduce cardiac complications.

    A prospective study was made of 40 consecutive patients who presented with peripheral arterial embolism to the Vascular Surgical Service in UKM. Atrial fibrillation was the most common source of the embolus. Twelve patients did not present until the affected limb(s) were in established gangrene. Thirty-two embolectomies were performed on 25 patients. Only 10 of these patients were discharged well with their limbs intact. Four patients required amputation because embolectomy did not restore viability of the limbs. Eleven patients died following embolectomy. The overall mortality for arterial embolism was 50%. Among the survival (n = 20), only 11 patients were discharged with their limbs intact. The cause of the poor result was related to the delay in definitive treatment and the poor general state of the patients. It was concluded that the prognosis for arterial embolism was very poor. This result needs to be improved and recommendations are made to achieve this.

    In a prospective case-control study over a two-year period involving 1006 women, 264 women with acute myocardial infarction (AMI), 305 with non-infarct acute coronary syndromes (CAD) were compared with 437 women with no coronary heart disease (Controls), to determine the relationship between cigarette smoking and other risks factors with coronary heart disease. A history of current cigarette smoking was strongly associated with the risk of coronary events for both AMI And CAD (p less than 0.001). 23.9% of patients with acute coronary syndromes were current smokers, compared with only 12.8% among controls. Overall, women smokers had about a two-fold increase in risk for all coronary events. Younger women smokers (less than 40 years) and those between 61-70 years had particularly higher risks (10.3 and 2.7 times respectively (p less than 0.01, p less than 0.02). A dose-response pattern of increased AMI risks (from 2.0 to 2.9 times) among women smokers was also found, corresponding to the number of cigarettes smoked per day (p less than 0.05). Other significant coronary risk factors established were: postmenopausal status (OR 6.5), diabetes mellitus (OR 5.1), hypertension (OR 1.6), family history of premature coronary heart disease less than 50 years (OR 1.3) and use of oral contraceptive pills (OR 1.4). Our results thus emphasize that cigarette smoking is an important determinant of acute coronary events even among Malaysian women.

    Over a 12 months period, out of 25,411 livebirths, 155 neonates (6.1 per 1000 livebirths) had proven septicemia by blood culture. The mortality rate was 26.5%. Septicemia was more common among the very low birthweight and preterm neonates of gestation of 30 weeks or less. 45.8% of the septicemia occurred during the first 48 hours of life. Staphylococcus epidermidis was the most common causative organism. However, mortality was highest among neonates who acquired multiresistant nosocomial infection during the later part of neonatal life.

    The objective of the study was to determine whether discriminant analysis of characteristics of dyspepsia can differentiate peptic ulcer from non-ulcer dyspepsia in a Malaysian population. Two hundred and twenty six patients with dyspepsia were interviewed using a standard history questionnaire before undergoing upper gastrointestinal endoscopy. Forty seven patients had peptic ulcer while 149 others were classified as having non-ulcer dyspepsia. Stepwise logistic regression analysis was done on 25 variables. The study showed that only five of these variables could differentiate peptic ulcer from non-ulcer dyspepsia, namely, nocturnal pain, pain before meals or when hungry, absence of nausea, age and sex. A scoring system was devised based on these discriminant symptoms. At a sensitivity of 51%, the specificity for peptic ulcer was 83%, but only prospective studies will determine if this scoring system is of actual clinical value.

    Patients attending a referral Skin Clinic were studied to identify the spectrum of drug eruptions and the offending drugs. There were 51 patients with an incidence of five per thousand and equal sex incidence. Though the pattern of eruption was broadly similar to other reports, unusual reactions were observed. In addition to the skin manifestation, fever and lymphadenopathy were present in most patients. Raised erythrocyte sedimentation rate and eosinopoenia were commonly observed. Clinical acumen and the list of drugs ingested are still the best clues to the diagnosis ofdrug eruption.

    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.

    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.

    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.

    PURPOSE: This prospective study was performed to determine if midstream urine (MSU) culture and sensitivity (C&S) alone could adequately predict infected urine proximal to the obstructing ureteral stone or the infected stones. Can pelvic urine C&S predict infected stones?

    MATERIALS AND METHODS: A prospective clinical study was performed on all patients undergoing ureterorenoscopy and lithotripsy for ureteral stones with obstruction between December 1, 2000 and January 31, 2002. We obtained MSU, renal pelvic urine and fragmented stones for culture and sensitivity. An analysis of the data was performed to assess statistical association.

    RESULTS: A total of 73 patients who fulfilled the criteria were recruited. Of these patients 25 (34.3%) had positive stone culture, 43 (58.9%) had positive pelvic urine and 21 (28.8%) patients had positive MSU C&S. Stone and pelvic C&S were positive simultaneously in 17 (23.3%) cases, MSU and stone C&S were positive in 8 (10.9%) cases, whereas pelvic and MSU C&S were positive in 13 (16.4%) cases (p = 0.03). MSU C&S had a sensitivity of 30.2% and specificity of 73% to detect pelvic urine C&S positivity. MSU C&S had a low positive predictive value and negative predictive value (NPV) in relation to infected pelvic urine (positive predictive value = 0.62, NPV = 0.42). Pelvic urine C&S had a NPV of 0.73 in detecting noninfected stones.

    CONCLUSIONS: The results of this study suggest that in obstructive uropathy secondary to a stone MSU C&S is a poor predictor of infected urine proximal to the obstruction and infected stones.

    The aim of this study was to determine the appropriateness of colonoscopy in relation to its diagnostic yield, with reference to the guidelines set by the American Society of Gastrointestinal Endoscopy (ASGE). A prospective 90-day audit was performed at Hospital Kualal Lumpur, which is a tertiary referral centre in Malaysia, to examine the appropriateness of colonoscopy by indication. During that time, 257 colonoscopies were performed in 244 patients. The predominant indications for colonoscopy were altered bowl habit (37%) and rectal bleeding (18%). Of the 257 colonoscopies, 216 (84%) were judged to be appropriate by ASGE guidelines. Only 43% of all colonoscopies had positive findings. Positive findings were found in 93% of cases judged appropriate compared with only 7% found in cases deemed inappropriate. There were statistically significant relationships between appropriateness and overall positive yield and between appropriateness and neoplastic findings (p < 0.05). Colonoscopy performed for appropriate indications yield more significant findings, this, we advocate the use of accepted guidelines to maintain or improve the standard colonoscopy services.

    Intramedullary nailing is an accepted procedures for femoral fractures gives uniformly good results. Various methods of intramedullary fixation have been practiced in the past. Recently intramedullary fixation without reaming has come into vogue. Preservation of the endosteal blood supply, less blood loss and quicker union have been the alleged benefits of not reaming the medullary canal. This study is a prospective randomised study conducted to compare intramedullary nail fixation of closed femoral fractures with and without a reaming procedure to assess the validity of the above assumptions. One hundred and two consecutive cases of skeletally mature patients with closed fracture of femoral shaft were randomised into two groups, i.e. Reamed (52) and Unreamed (50). The average follow-up was 36 weeks (range 28-86 weeks). Average time taken for various stages of the operation and total operating time were longer in the reamed group (109.9 min vs 78.6 min) and the blood loss was also increased (320 mls vs. 190 mls). Bridging and callus formation were seen to occur earlier in the reamed group compared to the unreamed enabling the patients in the reamed group to return to normal functions earlier. Limb length discrepancy and rotational alignment measured clinically and with CT scan did not however show any significant difference between the two methods. Nails used in this study group were notably of a smaller diameter and of shorter length when compared to those used in the western population highlighting the difference in the femur in the Asian population. Complications were notably more in the unreamed group where these were screw breakage (3/50) delayed unions (9/50) and non-unions (4/50). In the reamed group however there were only delayed union (2/50) and all fractures eventually united without any implant failure. We conclude that closed, reamed, antegrade insertion of an intramedullary nail is the treatment of choice in femoral shaft fractures, especially those involving the distal 1/3. The unreamed procedure should be reserved for certain exceptions, such as in polytrauma, where a shorter operative time and less blood loss is desired.

    We reviewed the results of screw osteosynthesis for the treatment of fracture lateral condylar physis in twenty children whose average age was six years old (range, two to ten years) at the time of operation from January 1998 till December 2000. The average interval between the injury and the operation was three and half days (range, one day to two weeks). The average duration of follow up was one year (range, one year to two years). Osteosynthesis was revised in two patients due to anterior placement of screw and rotated distal fracture fragment. Osseous union was achieved in all twenty patients. The result was rated excellent in nineteen patients and good in one patient.

    BACKGROUND: Mobilising patients early after stroke [early mobilisation (EM)] is thought to contribute to the beneficial effects of stroke unit care but it is poorly defined and lacks direct evidence of benefit.

    OBJECTIVES: We assessed the effectiveness of frequent higher dose very early mobilisation (VEM) after stroke.

    DESIGN: We conducted a parallel-group, single-blind, prospective randomised controlled trial with blinded end-point assessment using a web-based computer-generated stratified randomisation.

    SETTING: The trial took place in 56 acute stroke units in five countries.

    PARTICIPANTS: We included adult patients with a first or recurrent stroke who met physiological inclusion criteria.

    INTERVENTIONS: Patients received either usual stroke unit care (UC) or UC plus VEM commencing within 24 hours of stroke.

    MAIN OUTCOME MEASURES: The primary outcome was good recovery [modified Rankin scale (mRS) score of 0-2] 3 months after stroke. Secondary outcomes at 3 months were the mRS, time to achieve walking 50 m, serious adverse events, quality of life (QoL) and costs at 12 months. Tertiary outcomes included a dose-response analysis.

    DATA SOURCES: Patients, outcome assessors and investigators involved in the trial were blinded to treatment allocation.

    RESULTS: We recruited 2104 (UK, n = 610; Australasia, n = 1494) patients: 1054 allocated to VEM and 1050 to UC. Intervention protocol targets were achieved. Compared with UC, VEM patients mobilised 4.8 hours [95% confidence interval (CI) 4.1 to 5.7 hours; p
