From October 1996 to March 1997, 31 children with febrile convulsions were admitted to the University Hospital, Kuala Lumpur. Human Herpesvirus 6 (HHV 6) was virologically and/or serologically confirmed to be the cause of the febrile episode in 5 of these children (16.1%). Age, sex and other associated clinical features (diarrhoea, cough, running nose and type of seizure) were not useful in differentiating cases of febrile convulsion due to HHV 6 from those of other aetiology. However, uvulo-palatoglossal junctional ulcers were noted in children in whom the cause of the seizure could be attributed to HHV 6 but not in the remaining cases in the study group. HHV 6 DNA was detected in peripheral blood mononuclear cells from all patients with febrile convulsions attributed to HHV6, and in patients shown serologically to have already been exposed to the virus by nested polymerase chain reaction amplification. Only genotype HHV 6B was detected from patients with seizure due to HHV 6 but both genotype 6A and 6B were detected in the remaining cases studied.
Fifty-five patients were followed up after day surgery for breast lumpectomy. It was found that local infiltration with bupivacaine significantly decreased analgesic requirement in recovery. Almost half of the patients could not be contacted during the 24 hour post-operative follow-up by telephone. 7.1% complained of severe pain despite oral analgesics. 14.3% of patients had queries regarding wound care and 78.6% of the patients were willing to undergo day surgery again. Ongoing patient education and good post operative analgesia are crucial to enable successful establishment of ambulatory surgery. Post-operative follow-up is encouraged to audit clinical and social outcomes of day surgery.
We have studied the antiemetic efficacy of droperidol alone, and in combination with metoclopramide in first trimester termination of pregnancy in day surgery. The aim was to determine whether the addition of metoclopramide could further reduce the incidence of postoperative nausea and vomiting (PONV) but avoid excessive sedation. Group I (control, n = 40) received i.v. droperidol 0.625 mg at induction. Group II (study, n = 40) received i.v. droperidol 0.625 mg and i.v. metoclopramide 10 mg at induction. The incidence of nausea at 1 and 2 hours postoperatively was 23% and 10% in group I, and 5% and nil in group II respectively. The difference in the incidence of nausea was significant at p < 0.05 at one hour but not at two hours postoperatively. No patients vomited. There was no difference in the sedation and pain score between them. We did not observe any significant side effects attributable to either drug. All patients were discharged home within 3 hours. We conclude that in the prevention of PONV, the combination of metoclopramide and droperidol is superior to the use of droperidol alone at one hour but not at two hours postoperatively.
A case of persistent trophoblastic tissue on the pelvic peritoneum is presented. While most cases are secondary to conservative surgery for tubal ectopic pregnancy, primary implantation can also occur as highlighted by this case. A brief pathophysiology of the condition is presented. The importance of monitoring the serum for beta subunit human chorionic gonadotrophin (HCG) is emphasised.
Conjoined twins in a triplet pregnancy is an extremely rare occurrence. We present here, a 27-year-old multigravida with gestational diabetes and a conjoined twins in a triplet pregnancy.
Typhoid fever (TF), a systemic prolonged febrile illness, continues to be a worldwide health problem especially in developing countries where there is poor sanitation and poor standards of personal hygiene. The worldwide incidence of TF is estimated to be approximately 16 million cases annually with 7 million cases occurring annually in SE Asia alone. More than 600,000 people die of the disease annually. The pathogenesis of TF is beginning to be understood. The clinical features and diagnosis of TF are well known. New diagnostic methods have yet to gain universal acceptance. Traditional treatment with the first-line antibiotics (i.e. chloramphenicol, ampicillin and trimethoprim-sulphamethoxazole) though still being used in most developing countries are gradually being replaced with shorter courses of treatment with third generation cephalosporins or fluoroquinolones especially with the growing incidence of multi-drug resistant S typhi strains (MDR-ST). MDR-ST strains are particularly common in the Indian subcontinent; Pakistan and China. The presently available vaccines are far from satisfactory in terms of safety, efficacy and costs. Newer vaccines have been developed and are presently undergoing clinical trials in human volunteers.
Bell's palsy is a common neurological problem causing considerable loss of self-esteem among patients. A prospective observational study was conducted to determine the short-term outcome of Bell's palsy at 1 month and 2 months after the onset and the relationship between these outcomes with facial nerve degeneration. We also determined if gender, age, diabetes, systolic and diastolic blood pressure influence the severity of facial nerve degeneration and the clinical outcome at 2 months after the onset. After clinically grading the newly diagnosed unilateral Bell's palsy patients using the House-Brackmann facial nerve grading system, nerve conduction studies of the facial nerve were done to determine the severity of facial nerve degeneration. The recovery of the facial paralysis was clinically graded again at the end of 1 month and 2 months from the onset. A total of 37 patients were recruited. There was a strong positive correlation between facial nerve degeneration and the clinical outcome of Bell's palsy at 1 month (r = 0.794; p < 0.0005) and 2 months (r = 0.732; p < 0.0005) after the onset. There was no significant correlation between either the facial nerve degeneration or the clinical outcome at 2 months with the patients' age (p = 0.288 and p = 0.799 respectively), systolic blood pressure (p = 0.425 and p = 0.933 respectively) or diastolic blood pressure (p = 0.243 and p = 0.579 respectively). Neither the severity of facial nerve degeneration nor the clinical outcome at 2 months were significantly different between male and female patients (p = 0.460 and p = 0.725 respectively) or diabetic and non-diabetic patients (p = 0.655 and p = 0.655 respectively).
To retrospectively study the long term results of high tibial valgus osteotomy in management of primary medial compartment osteoarthritis, with special reference to patient satisfaction and functional assessment, we conducted this study in radiologically established 50 knees of patients with primary osteoarthrosis of knee. In these patients with medial compartment disease (varus knee), medial open wedge osteotomy was performed using full thickness iliac crest grafts. These were called for follow-up after average 7.5 years and clinico-radiological assessment was done. Although many surgeons of the west do not favour this osteotomy, we found the procedure to be quite acceptable to our patients in whom the primary concerns of cost and squatting habits are well taken care of. The authors feel that this osteotomy is still relevant in the third world. Results do deteriorate with time but most patients consider the surgery satisfactory.
Objectives: i) To determine the prevalence of smoking among the community aged 15 and above in Kg. Jenderam Hilir in Sepang District, Selangor state. ii) To determine the relationship between smoking and age, sex, household income and education. iii) To determine the parental and peer influence on smoking in Kg Jenderam Hilir.
Materials and Methods: A study was conducted to Kg Jenderam Hilir, Sepang. All residents aged 15 years and above from all the 381 households of Kg Jenderam Hilir were included in this study. A standardized pre-tested structured questionnaire was used in this study.
Results: Out of 894 respondents interviewed 69% were males compared to 3.9% of the females (overall 33.6%) reported to have smoked at least once in his/her lifetime. The difference was statistically significant. The mean duration of smoking was 17.7 years. The age at which smoking was first attempted ranged from 4 years to 51 years with a mean of 18.7 years. The mean initiation age for the males was significantly lower as compared to the mean initiation age for the females. The prevalence of current smokers was significantly higher amongst males (52.8%) as compared to the females (1.4%). The prevalence of smoking among current smokers increased with age (p<0.01). there was no significant difference in the prevalence of smoking by household income and educational level. The mean number of cigarettes smoked by current smokers per day was 14.9 cigarettes and ranged from 1 to 60 cigarettes. The mean number of cigarettes smoked by the males was significantly higher than the females (p<0.05). the mean duration of smoking among current smokers was 20 years. There was a significant difference in the level of addiction to smoking and the duration of smoking (p<0.05). sixty five percent of the current smokers reported to have tried to quit smoking while 26% of ever smokers had reported to quit smoking and remained non-smokers. The quit ratio was calculated to be 26.0%. the quit ratio was 52.6% among those with college or university education. There was a significant difference in the quit ratio by education level (p<0.01). There was no significant difference in smokers whose parents were smokers as compared to non-smokers whose parents were smokers. However, there was a significant association between smoking and peer influence (p<0.01).
The aim of this study was to determine the factors for the large size of intracranial meningiomas at the time of presentation to the Sarawak General Hospital. The data was collected prospectively from 1/3/2000 to 28/2/2001. During this period a total of 57 cases of intracranial tumours were operated upon. Twenty of these cases (35%) were meningioma, making meningioma the most common intracranial tumour operated in the Neurosurgery service here with one to two cases operated per month. Headache was the most common symptom. The average duration of symptoms before the diagnosis was made was twenty-five months, the longest being fifteen years. The patients needed an average of seven visits prior to the diagnosis.
A retrospective study was done on 302 patients who had undergone coronary artery bypass grafting (CABG) in Hospital Universiti Kebangsaan Malaysia--46.0% were Chinese, 40.1% were Malays and 11.6% were Indians. Overall and irrespective of race and sex, the prevalence of diabetes mellitus, hypertension and hyperlipidaemia was 45.7%, 78.8% and 89.1% respectively indicating that hyperlipidaemia was the most prevalent risk factor amongst this cohort. The Indians had the highest prevalence of the three risk factors. The Chinese and the Malays most frequently presented with the combination of hypertension and hyperlipidaemia.
The aim of this study was to assess the efficacy and safety of external cephalic version (ECV) when its use was introduced in the routine management of breech presentation and transverse lie after 36 weeks by obstetricians with limited prior experience with the procedure. The influence of various factors on the outcome of ECV was also studied.
OBJECTIVES: The nature of vascular trauma varies greatly between continents and across time. The aim of this study was to prospectively analyse the demographics, pathology, management and clinical outcomes of vascular injuries in two urban Malaysian hospitals and review of international literature on vascular trauma. From this information, preliminary management and preventive implications will be described.
METHODS: Eighty-four consecutive cases of trauma requiring vascular surgery were prospectively analysed over three years at Hospital Kuala Lumpur and Hospital Pulau Pinang, Malaysia. Extensive patient demographic and injury data, including the mechanism of injury, associated injuries, angiographic findings, operative details and post-operative complications, were systematically gathered.
RESULTS: Most vascular injuries were incurred by males (76/84), with 37% (28/76) of them aged between 21 and 30 years. Malays were most frequently injured (n = 36) followed by Chinese and Indians. Road traffic accidents (n = 49) substantially outnumbered all other causes of injury. Lower limb injuries (n = 57) occurred more than twice as often as upper limb injuries (n = 27). Complete arterial transections (n = 43) and intimal injuries (n = 27) were more common than arterial lacerations (n = 10) and pseudoaneurysms (n = 4). The most frequently damaged vessels were the popliteal/tibioperoneal trunk (n = 33). All patients received urgent Doppler ultrasound assessment and, where possible, ankle-brachial systolic index measurement. Of all patients, 40 received an angiogram, haemodynamic instability making this investigation impractical in others. Primary arterial repair was the most frequently employed surgical procedure (n = 54) followed by autogenous reverse long saphenous vein (LSV) interposition graft (n = 14), embolectomy (n = 5) and PTFE interposition graft (n = 3). The most common post-operative complication was wound infection (n = 11). Amputation, as a last resort, was required in 13 cases following either primary or autogenous reverse LSV repair complicated by sepsis or critical ischaemia.
CONCLUSIONS: Vascular trauma, especially in conjunction with severe soft tissue, nerve or orthopaedic injury carries colossal physical, psychological, financial and social costs. Associated nerve and venous injury portended poor outcome in this study. Whilst orthopaedic trauma was a common association, the concurrence of occult vascular trauma and soft tissue injury without fracture emphasises the crucial importance of thorough and rapid clinical vascular assessment, investigation and surgical intervention. Fasciotomy, especially for the lower limb, is important for the prevention of compartment syndrome and its, limb-threatening sequelae. Primary preventive road safety promotion and interventions, with attention to high-risk groups (young males and motorcyclists), is urgently required.
This is a retrospective review of 110 patients admitted to the Burns Units between October 1999 and November 2001. The aim was to determine the burns pattern of patients admitted to hospital UKM. There was an increasing trend for patients admitted. Female to male ratio was 1:2. Children consisted 34% of the total admission. Children had significant higher number of scald burns as compare to adult (p < 0.01). Domestic burns were consist of 75% overall admission. Mean percentage of TBSA (total body surface area) burns was 19%. Thirty percent of patients sustained more than 20% of TBSA. Sixty percent of patients had scald burns. Ninety percents of patients with second degree burns that were treated with biologic membrane dressing or split skin graft. Mean duration of hospital stay was 10 days. Over 70% of patients were discharged within 15 days. Overall mortality rate was 6.3%. The patients who died had significantly larger area of burns of more than 20% TBSA (p < 0.05) and a higher incidence of inhalation injury (p < 0.02). Hence, this study suggests a need for better preventive measures by the authority to prevent burns related accident and the expansion of the service provided by the Burns Unit.
Accessibility of research done locally to clinicians remains limited unless it is in the published form. The publication rate of research presentations at the Annual Malaysian Paediatric Association, Perinatal Society of Malaysia and Academy of Medicine Malaysia in 1997 and 1998 was determined. One hundred and five (95.5%) of 110 research presentations were carried out in Malaysia. Thirty-seven (35.2%) presentations were published. University-affiliated institutions were more likely to publish their research presentations as compared to Ministry of Health hospitals (OR 3.1 95% CI 1.4-6.8, p < 0.01). There is a need to encourage publication of local research presentations. University-affiliated institutions performed better due to institution pressure for career advancement.
Asthma knowledge an important components of asthma education.
Objective: To determine the levels of asthma knowledge in parents of asthmatic children and factors that may influence it.
Methods: This is a prospective study done between March 1998 and July 1998. Sixty-seven parents were interviewed using the 31 item asthma knowledge questionnaire that had been validated and translated. The children asthma severity was classified. The questionnaire includes biodata of children and parents, types of medication and dosage duration of asthma, exposure to cigarette smoke, acute asthma admission and patient’s economic status.
Results: This mean score for asthma knowledge was 15.5. The total score was 31. Asthma knowledge was significantly higher in parents whose children were using steroids [p=0.03, CI (-3.85, -0.02)]. It correlated significantly with steroid dosage (r=0.29, p=0.02), and was significantly higher in parents of higher economic status. Patient’s asthma knowledge had no association with children’s asthma status, age of the child or parents, exposure to cigarette smoke, frequency of admission of asthma duration.
Conclusion: The low asthma knowledge level indicates the need to increase the effort in educating parents. The main indicator for higher knowledge was steroid usage and dosage. Higher asthma knowledge in the high-income group was probably related to levels of education.

This is the first review on orthognathic surgery in Malaysia. The records of a total of 84 patients seen between 1977 and 1999 in the Department of Oral and Maxillofacial Surgery of the Faculty of Dentistry, University of Malaya were analysed. Skeletal III deformity formed 85% of the sample with a female dominance of 2 to 1. The patients' age ranged from 17 to 36 years, with a mean of 25.3 years. The common surgical techniques used were combined bilateral sagittal split and Le Fort I osteotomy. The predominant ethnic group was Chinese (n = 58, 69%); followed by Malay (n = 14, 17%) and Indian (n = 12, 14%).
Two hundred outpatients (115 females and 85 males) attending the University Malaya Medical Center (UMMC) eye clinic, aged 20 years and above and without any ocular surface disorder were recruited for this study. Their tear film status was determined subjectively by their symptoms and quantitatively by the cotton thread test, Schirmer's test, marginal tear film meniscus assessment, fluorescein corneal staining and tear break-up time. Dry eye was considered present if at least one symptom was experienced often or always, within the past 3 months. Dry eye was also considered present if one of these tests was positive; Schirmer's test < 5 mm, Phenol red thread (PRT) test < 10 mm and tear film breakup time (BUT) < 8 seconds. The prevalence of dry eye in this sample population as defined by presence of symptoms and an abnormal test result is 14.5%. Presence of dry eye as detected by clinical testing is higher in the Chinese race (p < 0.01), in the group 40-59 years (p = 0.024). There is no difference between females and males. A lower BUT score was more strongly associated with presence of dry eye symptoms (p = 0.02). Elderly patients have a lower BUT and Schirmer's score. There is lack of agreement between PRT and Schirmer's test, although both are measures of tear quantity.
