Sera obtained from 3,472 persons in Malaysia, Thailand, Philippines and Indonesia were tested for the presence of antibody to adult T-cell leukemia-associated antigen by the gelatin particle agglutination test and indirect immunofluorescence. Among these, only two seropositives were identified. One was a 30-year-old male Malaysian of Indian origin. The other was a 42-year-old female Thai who resided in Bangkok. These results suggested that the infection of human T-lymphotropic virus type 1 might not be endemic in these countries.
Six children who survived severe acute bronchiolitis in infancy and early childhood continued to have persistent symptoms of breathlessness, cough and wheeze resistant to bronchodilator therapy. Hyperinflation of the chest, widespread crepitations and rhonchi were persistent clinical features. Failure to thrive was a problem in most. At presentation clinical measles was diagnosed in one child and adenovirus titres were raised in another; the aetiological agents in the others were not known. Lung biopsy from the child with measles showed features of severe bronchiolitis. The clinical and radiological features and course of the illness were consistent with those of bronchiolitis obliterans. Although illness was prolonged the long term prognosis was satisfactory with the majority of children showing improved chest signs, growth and general health after four to eight years of follow up.
Demonstration of arrested intracerebral blood flow is the ultimate evidence of brain death. Computerized radionuclide cerebral flow study was done on 18 patients diagnosed clinically as brain dead. Correlation was made with clinical neurophysiological and EEG findings. The criteria for diagnosis of arrested intracerebral perfusion using radionuclide flow study were: non-visualization of blood flow activity in the intracranial arteries during the arterial phase, diffused cerebral activity during the capillary phase and non-filling of venous sinuses during the venous phase; visualization of typical 'hot nasal' activity; the time activity curve over the cerebral hemispheres lacks a bolus effect and instead shows a delayed gradual rise of activity. These features are pathognomonic of brain tamponade.
Arrested intracranial circulation was seen in 16 patients (ten had electrocerebral silence; one had extremely abnormal EEG with small voltage activity and five had no EEG done). In the remaining two patients, some cerebral blood flow was demonstrated (one had no definite cerebral activity and the other had diffused EEG activity).
Radionuclide cerebral flow study is a very sensitive, accurate, safe, simple, rapid and non-invasive modality in confirming brain death and is especially useful in patients on "brain-protection" regime, in hypothermia or in certain metabolic states where diagnosis based on clinical and EEG criteria is difficult. EEG need not be a required procedure once brain death is established by the demonstration of arrested intracranial circulation.
Perforated appendix is a serious surgical condition that carries a high morbidity. Antibiotic treatment is often started before the availability of bacteriological reports. The choice of antibiotics would depend on the bacteriology associated with perforated appendix. In a retrospective survey of the bacteriology of peritoneal pus obtained from cases of perforated appendix at the General Hospital, Kuala Lumpur, E. coli was found to be the most commonly encountered organism. This was followed in order of decreasing frequency by streptococci, Bacteroides species, Klebsiella-Enterobacter group and Pseudomonas aeruginosa. From the results of the antibiotic sensitivities an antibiotic regimen comprising of a combination of gentamicin, metronidazole and penicillin is recommended as appropriate chemotherapy in perforated appendix.
Health, including nuirition is not independent but is closely associated with the social and economic environment. Malnutrition itself can cause death, but more commonly, it can cause considerable ill-health, physical retardation, impaired mental performance, loss in productivity and a decline in the quality of life. The effects of malnutrition as obstacles to socio-economic development are now well recognised. In a rapidly developing country like Malaysia, the nutritional and nutritionally-related problems present themselves with contrasting features. While population indicators such as toddler mortality, incidence of low birthweight and food balance sheet studies suggest an improving nutritional situation, methods of direct assessment have shown that chronic protein-energy malnutrition and anaemia are sWI common amongst pre-school children in both the rural and urban disadvantaged sectors. Moderate anaemia also affects a significant proportion of older children and women of childbearing age. Intestinal parasites, another indicator of under development at the local level, are ubiquitous in the rural setting and urban slums owing to unsatisfactory waste disposal. In striking contrast, diseases associated with dietary excesses and increasing affluence have now emerged as the major killers. This changing pattern of mortality and morbidity along the lines encountered by the industrialised societies is now dramatised by the fact that road accidents are now claiming a large number of victims. It is clear that while continued efforts should be given to the improvement of the nutritional health of both rural and urban poverty communities, little time should be wasted in considering the adoption of public health measures aimed at stemming the rising number of deaths associated with our increasing affluence, particularly those diseases that are nutritionally linked, such as coronary heart disease, hypertension and diabetes mellitus, not forgetting the increasing road toll afflicted by the motor vehicle.
The findings of a cholera epidemic in Krian district is reported. There were 77 cases and 92 carriers in the epidemic. Although the three main ethnic groups of Malays, Chinese and Indians were involved in the epidemic, the Malays constituted majority of the cases and carriers. The overall infection rate and case attack rate was higher among the younger population. The case: carrier ratio was also higher among the younger population especially among Indians. Various reasons and probable causes of the epidemic have been described briefly.
Twenty children with retinoblastoma are reviewed who were treated at the University Hospital, Kuala Lumpur over a 10-year-period. They constitute 6.6% of childhood malignancies and without exception all presented with advanced disease. Hereditary cases were notably absent in the the series probably because past cases have almost invariably succumbed without an opportunity to transmit the gene. With enucleation and radiotherapy six of the patients have survived from 2 to 12 years. The addition of vincristine and cyclophosphamide has not been associated with improved survival.
To present an unusual case of a sphenochoanal polyp that regressed and review the etiology of such polyps in comparison to the commoner antrochoanal polyp.
AIM: To study the aetiology and clinical course of children with brainstem death in a paediatric intensive care unit (ICU) and to determine whether current the practices that are used to declare brainstem death conform to accepted criteria.
METHODS: A retrospective review chart of all patients with brainstem death (n = 31) admitted to the paediatric ICU between January 1995 and December 1998 was drawn up.
RESULTS: Mean age of the patients was 51.9 +/- 54.5 mo with the main diagnoses being head trauma in 11 children, anoxic encephalopathy in 7, brain tumour in 5, drowning in 4, CNS haemorrhage in 3 and CNS infection in 1 child; 32.3% of the children were given pre-ICU admission cardiopulmonary resuscitation. The average time from insult to suspected brainstem death was 27 h and suspected brainstem death to confirmation was 25 h, with an average of 1.6 examinations performed. EEG was done in 14 patients, with electrocerebral silence in 8 after the first examination and in a further 5 after repeat testing. Cerebral blood-flow scans were done in 3 children and evoked potentials in 1 child.
CONCLUSIONS: Trauma remains the most common primary diagnosis leading to brainstem death. Intensivists in this large hospital for children mainly conform to accepted guidelines for determination of brainstem death although there is a wider use of ancillary tests to aid diagnosis. The study also showed a low rate of < 10% of organ procurement for transplantation.

All children who underwent flexible bronchoscopy in the respiratory unit at Paediatric Institute, Hospital Kuala Lumpur from June 1997 to June 2002 were reviewed. A hundred and ten children underwent the procedure under sedation or general anaesthesia. The median age of these children was eight months. (Q1 3, Q3 30) The commonest indication for performing flexible bronchoscopy was for chronic stridor (50 cases) followed by persistent or recurrent changes such as lung infiltrates, atelectasis and consolidation on the chest radiographs (22). Laryngomalacia was found to be the commonest cause of stridor in 29 children. Two patients were diagnosed with pulmonary tuberculosis. With regard to safety, three procedures were abandoned due to recurrent desaturation below 85%. One of these patients had severe laryngospasm that required ventilation for 48 hours but recovered fully. Two neonates developed pneumonia requiring antibiotics following bronchoscopy. No patients developed pneumothorax or bleeding following the procedure. Bronchoscopy is a safe procedure when performed by well-trained personnel. Since it is an invasive procedure the benefits must outweigh the risks before it is performed.
This paper examines the surgical pathology associated with perioperative deaths in a country that is undergoing the transition from a developing to a developed nation status. The data from an ongoing nation-wide perioperative mortality study was prospectively collected for the period July 1996 to December 1997 and analyzed. The surgical pathology related to perioperative deaths in Malaysia is different from other developing and developed countries. While death from trauma and the late presentation of surgical conditions are similar to developing countries, infective gastrointestinal conditions were rarely encountered. Diseases associated with advanced age such as colorectal cancer, peptic ulcer, urological diseases and vascular conditions are beginning to emerge. As the country races towards a developed nation status, increasing life expectancy and changing life-styles are expected to influence the disease pattern. The planning of surgical facilities and manpower development must recognize the changes taking place.
