Existing criteria for admission of newborns to the special care nursery, Sarawak General Hospital, resulted in the admission of many neonates with certain risk factors ("at risk" neonates). To test whether such babies could be safely and better cared for in postnatal wards, 392 of these babies were randomly allocated into two groups. One group of 196 was admitted to the special care nursery and the other group of 196 was cared for with their mothers in the postnatal wards. The two groups were compared for mortality, morbidity and breastfeeding. There was no significant difference in mortality and morbidity between the two groups. While in hospital a larger proportion of babies cared for in postnatal wards were breastfed, compared to babies admitted to the special care nursery. In addition, they initiated their breastfeeding earlier. Babies with these risk factors should therefore be cared for with their mothers in the postnatal wards.
A retrospective review of patients with congenital dislocation of the hip (CDH) seen in the Institute of Orthopaedics, Kuala Lumpur General Hospital from 1975 to 1988 is presented. There was a female predominance of 17 to five. The average follow-up was 43 months and the average age at final assessment was 63 months. The results were assessed clinically and radiographically using Severin criteria. Eighty eight percent of the hips had excellent or good clinical results at final review compared with 40% of the hips which had excellent or good radiological grading (Severin I and II). Initial acetabular angle before treatment and types of treatment appeared to have a correlation with the final result. The incidence of avascular necrosis was 16%.
The objectives of this Malaysian study were to investigate the relationship between severity of trauma and interval before treatment, and the effect of delayed treatment on prognosis. A total of 123 traumatized permanent incisors were observed over a 24-month period. Results of this study suggest that the interval between trauma and emergency treatment is directly related to the severity of injury and the level of dental awareness of the patients. However, prognosis of these teeth is greatly influenced by the interval between trauma and initial treatment. Pathological pulp changes in these teeth can occur as late as two years after injury and this justifies the necessity for a long observation period following treatment.
From 1st January 1986 till 31st December 1986; 273 patients were treated in the Intensive Care Ward. The mortality in the Intensive Care Unit was 24.5%, mortality of patients 60 years and above was 35%. Of 187 patients who had survived, only 105 (56.2%) responded to the questionnaire, 39 (20.9%) did not respond and 43 (23.0%) could not be traced. Of the total discharged alive, 95 (51.9%) survived two years and eight (4.6%) died over the two years. Forty (41%) have returned to normal routine and are satisfied with their life style; 57 (59%) were not satisfied with their life style for various reasons, ill health being one. As regards patients above 60 years; 21 (53.8%) are alive and 10 (47.6%) are happy and satisfied with their life style.
Fifteen patients underwent surgery for cardiac tumours in General Hospital Kuala Lumpur between October 1984 and June 1989. Twelve of the patients had cardiac myxomas and underwent excision under cardiopulmonary bypass. Two patients had sarcoma, of which one was excised. The other was inoperable. Another patient had a metastalic malignant melanoma which was inoperable. Of the patients 10 were female and five male. Their ages ranged from 16 to 60 years. All were symptomatic and the commonest mode of presentation was exertional dyspnoea and palpitations. Two presented with cerebral embolisation. The three patients with malignant tumours had constitutional symptoms at the time of surgery. All patients had echocardiography pre-operatively to confirm the diagnosis of cardiac tumour. Only one patient underwent preoperative cardiac catheterisation and angiography. The surgical approach in all patients was through a median sternotomy and all except one were operated under cardiopulmonary bypass. There was no intraoperative embolisation. There was one perioperative death. Fourteen patients were followed up for periods ranging from one to 44 months. Three patients with malignant cardiac tumours died. One had recurrence of myxoma 21 months after the initial surgery. We conclude that excision of cardiac myxomas carry a very small risk following which patients have good prognosis. Malignant tumours carry a bad prognosis. From our experience, we conclude that echocardiography is an extremely accurate tool in the diagnosis of cardiac tumours.
A personal series of 163 patients who underwent coronary artery bypass surgery (CABG) in the University Hospital, Kuala Lumpur between March 1988 and December 1990 were reviewed retrospectively to determine factors affecting hospital morbidity and mortality. One hundred and thirty eight were elective cases while 25 patients underwent emergency CABG surgery. Of these, 15 patients had recent myocardial infarction, with unstable haemodynamics or post infarct angina; six had failed angioplasty procedures and four patients immediately following coronary angiogram. The elective hospital mortality rate was 2.2% (three cases) and there were two deaths in the emergency group. Pre-operatively 20 patients (13%) had very poor left ventricular function of less than 30% ejection fraction. Significant improvement in ejection fraction was observed following surgery. The follow-up periods were between three months to three years. Ninety eight percent of patients showed improvement in their functional status (NYHA classification) in relation to angina and exercise performance.
The effect of a capsulated palm-oil-vitamin E concentrate (palmvitee) on human serum and lipoprotein lipids was assessed. Each palmvitee capsule contains approximately 18, approximately 42, and approximately 240 mg of tocopherols, tocotrienols, and palm olein, respectively. All volunteers took one palmvitee capsule per day for 30 consecutive days. Overnight fasting blood was taken from each volunteer before and after the experiment. Serum lipids and lipoproteins were analyzed by using the enzymatic CHOD-PAP method. Our results showed that palmvitee lowered both serum total cholesterol (TC) and low-density-lipoprotein cholesterol (LDL-C) concentrations in all the volunteers. The magnitude of reduction of serum TC ranged from 5.0% to 35.9% whereas the reduction of LDL-C values ranged from 0.9% to 37.0% when compared with their respective starting values. The effect of palmvitee on triglycerides (TGs) and HDL-C was not consistent. Our results show that the palmvitee has a hypocholesterolemic effect.
A control programme against subperiodic brugian filariasis was implemented in three villages, (Kg. Ampungan, Kg. Sebangkoi and Kg. Sebamban) in Sarawak, Malaysia. In Kampong Ampungan, the mass administration of diethylcarbamazine (DEC-citrate) combined with residual house spraying of pirimiphos-methyl reduced microfilarial rate to 8% of the pre-treatment level and microfilarial density (MfD50) to 44% of the pre-treatment level over a period of four years. In Kampong Sebangkoi and Kampong Sebamban, where only mass DEC therapy was applied, the microfilarial rate and MfD50 declined distinctly in the second blood survey but increased gradually in two subsequent follow-up blood surveys. In Kg, Ampungan, we observed a significant reduction of infective biting rate (88.3%), infection rate (62.5%) and transmission potential (88.1%) of Mansonia bonneae at the fourth spray round. The corresponding reduction rates in Kg. Sebangkoi and Kg. Sebamban were 35.3%, 26.7%, 42.2% and 24%, 30.8% and 15.4% respectively. The biting density of the vector was reduced by 79.8% indoors and 31.8% outdoors at the sprayed village, while only a slight decrease in densities (17.9% indoors and 12.4% outdoors) was observed at the unsprayed village. Bioassay tests revealed that pirimiphos-methyl had a substantial fumigant effect on the vector. The integrated control measure in controlling subperiodic brugian filariasis is discussed.

Health workers in Malaysia randomly assigned either a low-dose triphasic or a low-dose monophasic oral contraceptive (Triquilar and Marvelon, respectively) to 198 women to examine discontinuation rates and reasons for discontinuation. 15.3% of Triquilar women and 9.1% of Marvelon women forgot to take 1 pill at some time during the study while 6.1% and 3% forgot to take at least 3 consecutive pills. There were more complaints and/or complications among Triquilar women than among Marvelon women. The most serious complication was severe headaches (only 1 woman from each group). 2 women in the Marvelon group complained of either generalized itchiness or digestion impairment. Complaints of women in the Triquilar group included localized and generalized itchiness, weight gain, digestion impairment, dryness of vagina, and numbness of extremities. Women in the Triquilar group were more likely to have menstrual complaints than those in the Marvelon group (14.3% vs. 9.1%). The leading menstrual complaint in both groups was spotting (6.1% vs. 4%). No Marvelon women reported menorrhagia, scanty menses, or intermenstrual pelvic pain or discomfort while at least 1 woman did from the Triquilar group. The percentage of women with changes in complaints since admission were the same for both groups. Total discontinuation rates which included lost to follow ups were 46.9% and 40%, respectively. The most common reason for discontinuation for both groups was desired method change (11.2% Triquilar and 14.1% Marvelon). Method unrelated reasons (unable to return to clinic, moving/travel, and not interested in the study) were the next most common reason for discontinuation. 3 women conceived while taking Triquilar. These pregnancies were attributed to method failure, perhaps due to incomplete pituitary suppression. There were no accidental pregnancies in the Marvelon group.
A prospective study of 100 consecutive patients with basal skull fracture admitted to the University Hospital, Kuala Lumpur between July 1986 and October 1988 was carried out to study its epidemiological pattern, clinical and radiological presentations, mechanisms of injury, time interval between accidents and neurosurgical referrals, complications and outcomes. Two-thirds of the patients were between 20 and 50 years old and 79% were male. Half of the injured were motorcyclists and 22% were pedestrians. Three-quarters of the patients were seen within an hour after injury. Thirty-two patients had intracranial haematomas: 14 subdural, 9 extradural and 9 intracerebral. Three patients developed meningitis (two after operations) and six developed epilepsy. Eighteen patients died, but good recovery resulted in 70 patients at follow-up of 1 to 28 months. A small subgroup of 15 patients with severe ear and nose bleeding as a result of basal venous sinus tear died within a few hours despite aggressive resuscitation, probably due to underlying severe brain stem injury. The implication of the high incidence of basal skull fractures in motorcyclists, despite the enforcement of crash helmets is discussed, with possible mechanisms proposed.
This prospective study was performed to quantify glucose-6-phosphate dehydrogenase (G6PD) enzyme activity in deficient males and female heterozygotes. The methods used in the study were the fluorescent spot test, G6PD enzyme electrophoresis on cellulose acetate and quantitative assays. Forty-seven children who had been detected as spot screen deficient at birth were rescreened. Their first degree relatives were also included in the study. The mean enzyme activity of deficient males was 0.74 iu/g Hb (s.d. +/- 0.8), of female heterozygotes was 6.5 iu/g Hb (s.d. +/- 3.2) and of normal males was 12.1 iu/g Hb (s.d. +/- 3.5). The mean activity in deficient males was 6.1% of normal males. Most (35 of 47) of these fell into class 2 in Beutler's classification of G6PD variants. This indicates a population which may be susceptible to favism. Female heterozygotes had an intermediate enzyme activity with a wide scatter. Using a cut off point of enzyme activity of below 9.0 iu/g Hb gave sensitivity and specificity of 87% and 84% in detecting female heterozygotes. This group could be defined more accurately by combining quantitative assays with family studies.
The effect of parity on the hematological response to supplemental hematinics and the relationship between birth weight and Hb concentration were examined in 67 pregnant rural Kelantanese Malay women recruited at 20-24 weeks of gestation. Among initially anemic women (Hb concentration at recruitment < 110 g/l), a significant supplementation effect was observed in the lower parae (3 or less children) but not in the higher parae. Among initially nonanemic women, a progressive decline in mean Hb concentration was observed in the higher parae; in the lower parae, however, an initial fall in mean Hb concentration was followed by a rise to almost the initial level. Birth weight was inversely related to initial Hb concentration. There was no association between birth weight and final measured Hb level, parity or any of the measured maternal characteristics. These observations suggest: a) women with initially lower Hb concentration might have experienced a greater acceleration of plasma volume expansion than those with initially higher Hb level; and b) hemopoiesis might be impaired in the higher multiparae.
To evaluate the effects of simple compensated fixed-dose iodine-131 therapy for thyrotoxicosis, the long-term results for 74 patients treated with a fixed dose of iodine-131 ranging from 5 to 12 mCi (185 to 444 MBq) were evaluated in the first 2 years of a trial. The dose selected was loosely based on the gross size of the thyroid gland. Routine antithyroid drug therapy was given for a minimum of 3 months after iodine-131 therapy. The mean (+/- SD) duration of follow-up was 74.5 +/- 42 months. The results indicated that roughly 25% of patients treated in this way will become hypothyroid after 5 years and that 85% are cured (need no further therapy during the follow-up period) using a single dose of iodine-131. Of those cured using a single iodine-131 dose, 81% were no longer receiving drugs after 6 months and 85% after 1 year. Such a regimen seems currently to be among the best available where prolonged periods of medication-free euthyroidism after therapy are sought.
From 1988 to 1990, eighty operations on eighty knees of seventy-nine patients with a clinical diagnosis of meniscal tear was entered into a prospective study. The clinical diagnosis was correct in 76% of patients. Excellent or good results were achieved in 90% of knees which had only meniscal lesions but dropped to 70.5% when other intraarticular pathologies coexisted with the meniscal lesions. Excellent or good results were achieved in 71% of the knees in the presence of Anterior Cruciate Ligament (ACL) deficiency.
The treatment of perforated duodenal ulcer is controversial. Since the advent of H2 antagonists, the number of ulcer operations has declined tremendously. We wanted to find out if the addition of a H2 antagonist after simple closure of a perforated duodenal ulcer would change the outcome and therefore reviewed 46 patients treated in this fashion. Our results show that this is a safe and effective way of treating patients with perforated duodenal ulcer.
Amiodarone, a commonly used antiarrhythmic agent, has numerous adverse effects. The purpose of this case report is to highlight its hepatotoxicity, an unusual complication of long term amiodarone therapy. Our patient is a 76-year-old man with underlying ischaemic heart disease and recurrent ventricular tachycardia. Eleven months after commencing amiodarone, he developed asymptomatic raised aminotransferases which resolved following drug withdrawal. Amiodarone was then reintroduced and four years later, the patient developed hepatomegaly, worsening liver biochemistry and histopathological changes consistent with early cirrhosis. His symptoms improved following discontinuation of amiodarone. However, hepatomegaly and a low serum albumin still persist four years later.
Actinic prurigo is a chronic familial photodermatitis found predominantly among the Amerindians. It has been reported from North and South America, Britain and Japan. We report a case of actinic prurigo seen in Singapore. A 20-year-old Malay female presented with a persistent pruriginous eruption in the sun-exposed parts and on her abdomen. She also had lower lip cheilitis and thinning of the outer eyebrows, features often seen in actinic prurigo. The minimal erythema dose to ultraviolet A (UVA) and UVB were persistently lowered. We propose that this condition be called actinic prurigo, tropical (South-East Asian) variant.

From 1981 to 1989, 12 patients of the University Hospital, Kuala Lumpur, were diagnosed to have Evans syndrome based on direct antiglobulin test (DAT) positive haemolytic anaemia and immune thrombocytopenia occurring either simultaneously (7 patients) or consecutively (5 patients). Their mean age at presentation was 24.8 years with a marked female preponderance. All 12 patients were given high dose steroid after diagnosis. Subsequently, other modalities including intravenous immunoglobulin (1 patient) and high dose methylprednisolone (1 patient) were given. Three patients died of intracranial haemorrhage during the first admission while 1 patient died of pulmonary embolism six months after diagnosis. Three patients had splenectomy because of thrombocytopenia. Six patients tested positive for antinuclear factor and antibodies to double stranded DNA and four of them died. Positive serology appeared to be associated with a poorer prognosis. Follow up observations indicate that patients who survive the acute attacks fare reasonably well.
