    A hospital study was carried out to compare parenting stress among 87 Malaysian mothers of children with cerebral palsy and a control group (comprising 87 mothers of children without disability who attended the walk-in paediatric clinic), using the Parenting Stress Index (PSI) questionnaire. Multiple regression analysis was used to determine socio-demographic and medical factors associated with child-domain stress (CDS) and parent-domain stress (PDS). Mothers of children with cerebral palsy scored significantly higher than control subjects on all sub-scales of CDS and PDS (p < 0.01), except for the sub-scale of 'role restriction'. The presence of cerebral palsy (p < 0.001) and activities of daily living (ADL) scores (p < 0.001) were significantly associated with CDS. Factors predictive of PDS were ADL scores (p < 0.001), number of hospitalizations over the past year (p = 0.024), level of maternal education (p = 0.018) and Chinese mothers (p < 0.001). Although this study demonstrated that Malaysian mothers of children with cerebral palsy experienced higher levels of stress than controls, the impact of cerebral palsy per se on parenting stress was modified by other factors such as increased care-giving demands, low maternal education and ethnic background. Habilitation should be directed at easing the burden of daily care, minimizing hospital re-admissions and targeting appropriate psychosocial support at specific subgroups to change parental perception and expectations.

    Paediatric intensive care in Malaysia is a developing subspecialty with an increasing number of specialists with a paediatric background being involved in the care of critically ill children. A part prospective and part retrospective review of 118 consecutive non-neonatal ventilated patients in University Hospital, Kuala Lumpur was carried out from 1 June 1995 to 31 December 1996 to study the clinical epidemiology and outcome in our paediatric intensive case unit (PICU). The mean age of the patients was 33.9 +/- 6.0 months (median 16 months). The main mode of admission was emergency (96.6 per cent) with an overall mortality rate of 42 per cent (50/118). The mean paediatric risk of mortality (PRISM) score was 20 +/- 0.98 SEM, with 53 per cent of patients having a score of over 30 per cent. Multiorgan dysfunction (MODS) was identified in 71 per cent of patients. Admission efficiency (mortality risk > 1 per cent) was 97 per cent. Standardized mortality rate using PRISM was an acceptable 1.06. The main diagnostic categories were respiratory (32 per cent), neurology (22 per cent), haematology-oncology (18 per cent); the aetiology of dysfunction was mainly infective. Non-survivors were older (29.5 vs. 13.8 months, p < 0.0001), had more severe illness (mean PRISM score 30 vs. 14, p < 0.0001), were more likely to develop MODS (96 vs. 53 per cent, p < 0.0001) and required more intervention and monitoring. Paediatric intensive care in Malaysia differs widely from that in developed countries in patient characteristics, severity of illness, and care modalities provided.

    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 diabetes mellitus and impaired glucose tolerance and their association with cardiovascular risk factors. The overall prevalence of diabetes mellitus was 10.5% and impaired glucose tolerance was 16.5%. There was no difference in the prevalence of diabetes mellitus between males and females but the prevalence of impaired glucose tolerance was higher in females (19.0%) than in males (11.5%). Subjects with diabetes mellitus were more obese (38.4%) than normal subjects (24.1%). They also had a higher prevalence of hypertension (12.9%) and hypercholesterolaemia (71.9%) than normal subjects. Subjects with impaired glucose tolerance also had a higher prevalence of obesity (35.5%), hypertension (9.0%) and hypercholesterolaemia (63.0%) than normal subjects. In conclusion, the prevalence of diabetes mellitus and impaired glucose tolerance was high and they were associated with a high prevalence of obesity, hypertension and hypercholesterolaemia.

    The demographic characteristics, risk behaviourand prevalence of other sexually transmitted diseases (STDs) were determined in 132 HIV-infected individuals seen in a Dermatology cum Genitourinary Clinic, Hospital Sultanah Aminah Johor Bahru. Sixty-one (46.2%) were Malays, 37.9% Chinese, 10.6% Indians and 5.3% were of other ethnic groups. The male to female ratio was 4.5:1. Most of the patients (82.5%) were between 20 to 40 years-old. Seventy (53.0%) were single, 34.1% were married and 7.5% were divorcees. The majority of them (97.7%) were heterosexual. Fifty seven (53.3%) of our male patients patronised commercial workers. Eighty-one (61.8%) were not intravenous drug users (IVDU). Of the 50 IVDUs, 24 had multiple sexual exposures. Fifty-three (48.2%) of the 109 patients screened for STDs had one or more other STDs. Thirty-four patients (31.9%) reported one STD in the past and 3.6% reported two STDs in the past. Fifty-six patients (42.4%) had developed AIDS. Thirteen had passed away. The main mode of transmission of HIV infection in this population is through heterosexual intercourse and the prevalence of STDs is high. These findings indicate a need to advocate responsible sexual behaviour and to detect as well as treat STDs early to prevent the sexual transmission of HIV.

    Sixty inpatients with diabetic foot were studied prospectively at the Orthopaedic wards of Hospital Kuala Lumpur. Data was evaluated to document the patient profile and the factors that were associated with a major amputation (either above knee or below knee) of the lower limb. Factors that were associated with increased risk of amputation were a low education level, manual occupation, poor foot care, peripheral vascular insufficiency of the lower limb, insulin dependence, anaemia and leucocytosis. However only anaemia, leucocytosis and hyperglycaemia were statistically significant in predicting a more adverse surgical procedure. This study recommends that foot care awareness and practice is important. This can be effectively dealt with at specially organised, multi disciplinary Diabetic Foot Clinics.

    An observational study was carried out in the Kuala Lumpur Maternity Hospital to determine the risk factors associated with feed intolerance in very low birthweight (VLBW, <1501 g) infants given intermittent 3-hourly enteral feeds within 72h after birth. Feed intolerance developed in 85 (64.4 per cent) of 132 infants. Logistic regression analysis showed that the only significant risk factor associated with feed intolerance was the age when the first feed was commenced. For each hour delay in the age of the infants when the first feed was given, the adjusted odds ratios of feed intolerance was 1.03 (95 per cent confidence intervals: 1.01-1.05; p = 0.01). Other factors (modes of delivery, Apgar score at 1 min, sex, ethnicity, history of resuscitation at birth, birthweight, gestation, multiple pregnancy, perinatal asphyxia, types of milk, hypothermia before first feed, hypotension before first feed, respiratory distress syndrome, patent ductus arteriosus, septicaemia, theophylline therapy, indomethacin therapy, ventilatory support, continuous positive airway pressure, umbilical catheterization, and surfactant therapy) were not significantly associated with feed intolerance. Our study suggests that to promote tolerance of enteral feeds in VLBW infants, intermittent orogastric feeds should be commenced as soon as possible during the first 72 h of life.

    INTRODUCTION: Although the majority of patients with primary hyperparathyroidism have a relatively asymptomatic benign disorder, there are patients who have a more aggressive disorder.

    CLINICAL PICTURE: We report a case of primary hyperparathyroidism presenting during pregnancy complicated by antepartum haemorrhage and severe prematurity. The diagnosis was made postpartum, when her problems rapidly progressed to result in severe neuromuscular weakness, bilateral pathological hip fractures as well as nephrolithiasis.

    TREATMENT: Surgical parathyroidectomy was performed. The underlying lesion was a large solitary parathyroid adenoma with cystic elements.

    CONCLUSION: Primary hyperparathyroidism is not an innocuous disease and can result in severe morbidity if left untreated.

    Objective: The frequency of the HLA class II antigens (HLA DR, DQ and DP) were determined among Malay patients with systemic lupus erythematosus (SLE) to ascertain the role they play in disease susceptibility. Study design: Fifty-six Malay SLE patients on follow-up at the SLE Clinic of the National University of Malaysia Hospital, Kuala Lumpur were enrolled into the study. Controls were taken from healthy unrelated individuals, ethnically-matched. Materials and Methods: Five ml of anticoagulated blood was taken from each patient and control and DNA extracted. The HLADR, DQ and DP antigen/allele frequencies were determined by the technique of modified PCR-RFLP and statistical analysis done by Chi-square and Fischers exact test. Relative risk was determined by the odds ratio and significant p values were corrected for the number of antigens/alleles tested. Results: We found that the DR2 antigen was significantly increased among the patients (85.7%) as compared to controls (61%)(p corr=0.03, RR=3.83). As for HLA-DQA1, the allele most commonly found among the patients was *0102 (57 vs 49.2%). HLA-DQA1* 0601 was slightly decreased among the patients but this finding was insignificant. Both HLA-DQB1*0501 and 0601 were found to be increased among the patients even after correction of multiple comparisons made (p=0.0036, RR=4.56 and p=0.0048, RR=6.0, respectively). However, HLA-DQB1*0503 and 0301 was slightly decreased in the sle patients though not statistically significant. The frequency of HLA-DQB1*0201 was insignificantly increased among the patients. Limited studies on the DPB1 locus shows the uncertain role of this antigen in contributing to disease susceptibility. However, our analysis of the HLA-DPB1*0901 showed a slight increase among the patients as compared to controls but failed to remain significant after being corrected with number of comparisons made. All other HLA-DPB1 alleles exhibited similar frequencies between sle patients and controls. Conclusion: From this study we suggest that HLA DR2, DQB1*0501 and *0601 may be important genetic factors in conferring disease susceptibility in the Malay SLE population of Malaysia.

    BACKGROUND: The Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) is an objective and appropriate scoring system for risk-adjusted comparative general surgical audit. This score was devised in the UK and has been used widely, but application of POSSUM to centres outside the UK has been limited, especially in developing countries. This prospective study validated its application in a surgical practice with a different population and level of resources.
    METHODS: All general surgical patients who were operated on under regional or general anaesthesia as inpatients over a 4-month period at Sarawak General Hospital in 1999 were entered into the study. All data (12 physiological and six operative factors) were analysed for mortality only with the POSSUM equation and the modified Portsmouth POSSUM (P-POSSUM) equation. Comparisons were made between predicted and observed mortality rates according to four groups of risk: 0-4, 5-14, 15-49 and 50 per cent or more using the 'linear' method of analysis.
    RESULTS: There were 605 patients who satisfied the criteria for the study. Some 56.7 per cent of patients were in the lowest risk group. The POSSUM predictor equation significantly overestimated the mortality in this group, by a factor of 9.3. The overall observed mortality rate was 6.1 per cent and, again, the POSSUM predictor equation overestimated it at 10.5 per cent (P < 0.01). In contrast, the observed and predicted mortality rates for all risk groups, including the predicted overall mortality rate of 4.8 per cent, were comparable when the P-POSSUM predictor equation was used.
    CONCLUSION: The POSSUM scoring system with the modified P-POSSUM predictor equation for mortality was applicable in Malaysia, a developing country, for risk-adjusted surgical audit. This scoring system may serve as a useful comparative audit tool for surgical practice in many geographical locations.

    We describe what we believe is the first reported case of a sublingual hematoma secondary to severe hypertension. The patient, a 77-year-old woman, experienced a spontaneous hematoma of the floor of the mouth, tongue, and sublingual space that eventually caused an airway obstruction. We performed an emergency tracheostomy under local anesthesia and then evacuated the hematoma through an incision along the floor of the mouth. The patient recovered uneventfully.

    The aim of this study was to investigate the incidence of IgG anticardiolipin antibody (ACL) and IgG anti-beta(2) glycoprotein I antibody (anti-beta2GPI) positivity in patients with primary or secondary antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE), to assess the association between IgG ACL and anti-beta2GPI, and the relationship between the presence of ACL and anti-beta2GPI with the clinical manifestations of APS. IgG ACL and IgG anti-beta2GPI levels were measured in 51 SLE patients, 20 patients with SLE and APS (secondary APS) and 11 primary APS patients using commercially available ELISA kits. Relationships between laboratory data and clinical manifestations of the patients were examined. The incidence of IgG ACL positivity was significantly higher in primary (36.4%) and secondary (40%) APS than in SLE (13.7%) patients (P = 0.02). The incidence of IgG anti-beta2GPI positivity was significantly higher in primary (54.5%) and secondary (35%) APS than in SLE (7.8%) patients (P = 0.0006). Mean levels of IgG ACL and anti-beta2GPI were significantly higher in the primary and secondary APS than in the SLE patients (P = 0.002 for both). A significant relationship was found between IgG ACL and IgG anti-beta2GPI (P = 0.01, R(2) = 0.56). There was a significant correlation between the presence of IgG ACL and a history of thrombosis in the combined primary and secondary APS group, but not in SLE patients. In conclusion, in this study IgG ACL and IgG anti-beta2GPI are closely related and mean levels of IgG ACL and IgG anti-beta2GPI are higher in patients with either primary or secondary APS than in SLE patients.

    Diabetes mellitus is an important risk factor for the development of coronary artery disease. The presence of microalbuminuria, which indicates renal involvement in diabetic patients, influences the progression of coronary artery disease. New coronary risk factors such as C-reactive protein (CRP), Lipoprotein a [Lp (a)] and fibrinogen are increasingly being recognized as important cardiovascular prognostic factors. These new coronary risk factors could account for the worse cardiovascular prognosis in diabetic patients with microalbuminuria. Our cross sectional study was to compare the prevalence of elevated CRP and the levels of Lp (a) and fibrinogen between diabetic patients with microalbuminuria and those without microalbuminuria. Diabetic patients with overt coronary artery disease were excluded from the study. A total of 108 patients were recruited of which 57 patients had microalbuminuria and 51 were without microalbuminuria. There was no difference in the number of patients with elevated CRP between these two groups. There were also no significant differences in the mean values of Lp (a) and fibrinogen between diabetic patients with and without microalbuminuria. The inflammatory marker CRP and coagulopathy markers i.e. Lp (a) and fibrinogen seem not to be perturbed in diabetic patients with microalbuminuria.

    Sewage sludge from aerobic treatment plant was found to contain high amounts of heavy metals. Research was carried out to investigate the speciation and leaching behavior of heavy metals when using high temperature melting technology for treatment. This was achieved by conducting a sequential chemical extraction procedure and EP-TOX leaching test. The thermal treatment led to increased shift of metals from organic fraction to residual fraction, indicating that the thermal treatment caused metals in sewage sludge to become stable. Furthermore, results from leaching test revealed that metals were not leached from the final product after thermal treatment and this was verified using US EPA standard limits. Results from this study indicated that melting technology could convert the sludge to product that can be either reused or landfilled without an adverse environmental impact.

    OBJECTIVE: In southeast Asia, pulmonary tuberculosis (TB) is the most frequently presumed diagnosis for haemoptysis. This study was designed to assess the causes of haemoptysis, the diagnostic yield of causes in different diagnostic modalities and the distribution of older patients.

    METHODS: All patients presenting to the University of Malaya Medical Centre, Kuala Lumpur, Malaysia with haemoptysis were recruited prospectively and evaluated.

    RESULTS: One hundred and sixty patients were evaluated for haemoptysis; 71 (44.4%) were aged 60 years or more. Significantly more patients smoked in the older age group (P = 0.002). The main causes of haemoptysis in the older patients were bronchogenic carcinoma (49.3%), pneumonia (11.3%), bronchiectasis (8.6%), cryptogenic (5.6%) and active TB (4.2%). Significantly more older patients had carcinoma (P < 0.001), while the younger patients more often had TB (P < 0.001). Chest pain was significantly more common in the older patients (P = 0.025), particularly in patients with carcinoma. Bronchoscopy alone or combined with CT of the thorax was significantly more diagnostic in the older patient (P = 0.006).

    CONCLUSION: Bronchogenic carcinoma is the commonest cause of haemoptysis in patients aged 60 years and above. Presumptive anti-TB therapy should not be encouraged despite the regional high prevalence of TB.

    Pregnancy complicated by lung cancer has been rarely reported. The regional incidence of this complex situation is likely to increase in the future and optimal management needs to be established to better deal with this situation. We report two patients with metastatic lung cancer complicating pregnancy to highlight the evaluation and management difficulties associated with this problem and to contribute to the limited information in the literature.
