    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.

    Late acute respiratory distress syndrome (ARDS) is associated with a mortality of more than 80%. Recent reports in adults have shown improved survival in late ARDS treated with prolonged course of steroids, however little data are available in children concerning its safety and efficacy. We report the successful treatment of a child dying from refractory late ARDS using a prolonged course of high-dose methylprednisolone instituted after 12 days of advanced mechanical ventilation. Progressive improvement was seen from days 3, 7, 10 and 14 after treatment with improvement in PaO2/fraction of inspired oxygen (FiO2) ratios, lung injury score and chest radiographical score. Treatment was complicated by a fungal urinary tract infection that was easily controlled. There were no major metabolic side effects. Steroid therapy can be considered in the treatment of children with refractory late ARDS but larger prospective studies are needed to define indications, timing, dosing and safety of this mode of treatment in children.

    Acute myopathy complicating treatment of status asthmaticus has been increasingly recognized since its original description in 1977. We report a case of an 11-year-old boy with severe asthma requiring mechanical ventilation. He was given high doses of parenteral steroids and neuromuscular blockade with non-depolarizing agents in order to achieve controlled hypoventilation with an ensuing hypercapnoea. He developed rhabdomyolysis with elevated creatinine kinase and renal impairment secondary to myoglobinuria. Electrophysiological studies revealed myopathic abnormalities. The aetiology for this myopathy appears to be related to therapy with parenteral steroids, muscle-relaxant agents and respiratory acidosis. Patients treated with steroids and neuromuscular blocking agents should be regularly monitored for development of myopathy.

    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.

    Inhaled nitric oxide (iNO) improves oxygenation in term and near-term infants with persistent pulmonary hypertension of the newborn (PPHN) and decreases the need for treatment with extracorporeal membrane oxygenation (ECMO). This mode of treatment is currently being introduced in Malaysia. We report our preliminary experience using low dose inhaled nitric oxide (20 parts per million) in three newborn infants (meconium aspiration syndrome, primary PPHN and congenital diaphragmatic hernia) with severe PPHN who fulfilled criteria for ECMO with a mean oxygenation index (OI) of 40. Two of the infants showed rapid and sustained improvement in oxygenation with a reduction in oxygenation index (OI) over 24 hours. The infant with diaphragmatic hernia showed an initial improvement in OI, which was unsustained and subsequently died. All three infants did not show significant elevation of methemoglobin or nitrogen dioxide (NO2). Inhaled nitric oxide is an effective and safe treatment for severe PPHN that can be used in a developing country like Malaysia.

    Twenty-two (42 per cent) out of 52 patients admitted with severe bronchiolitis to our Paediatric Intensive Care Unit required ventilation. Risk factors associated with ventilation included a younger mean age, female sex, low birthweight, failure to thrive and the presence of an underlying illness. Ventilated patients were also more likely to have a higher respiratory distress assessment index (RDAI) score, pneumonic infiltration on chest X-ray, lower serum sodium and a positive respiratory syncytial virus isolation in the tracheal secretion.

    Hyperimmunoglobulin E syndrome (HIE) is a rare condition characterised by marked elevation of serum IgE level, chronic dermatitis, intense pruritus, and recurrent serious infection. The major organism is usually S aureus. We report a case of an infant with HIE, who had pulmonary nocardiosis. The clinical features, immunological abnormalities, and radiological features of the condition are described. The child finally succumbed to the complications of pulmonary nocardiosis.

    The 24 h availability of intensive care consultants (intensivists) has been shown to improve outcomes in adult intensive care units (ICU) in the UK. We tested whether such availability would improve standardised mortality ratios when compared to out-of-hours cover by general paediatricians in the paediatric ICU setting of a medium-income developing country. The standardised mortality ratio (SMR) improved significantly from 1.57 (95%CI 1.25-1.95) with non-specialist care to 0.88 (95%CI 0.63-1.19) with intensivist care (rate ratio 0.56, 95% CI 0.47-0.67). Mortality odds ratio decreased by 0.234, 0.246 and 0.266 in the low, moderate and high-risk patients. 24 h availability of intensivists was associated with improved outcomes and use of resources in paediatric intensive care in a developing country.

    OBJECTIVES: To compare the modes of death and factors leading to withdrawal or limitation of life support in a paediatric intensive care unit (PICU) in a developing country.

    METHODS: Retrospective analysis of all children (< 12 years) dying in the PICU from January 1995 to December 1995 and January 1997 to June 1998 (n = 148).

    RESULTS: The main mode of death was by limitation of treatment in 68 of 148 patients, failure of active treatment including cardiopulmonary resuscitation in 61, brain death in 12, and withdrawal of life support with removal of endotracheal tube in seven. There was no significant variation in the proportion of limitation of treatment, failure of active treatment, and brain death between the two periods; however, there was an increase in withdrawal of life support from 0% in 1995 to 8% in 1997-98. Justification for limitation was based predominantly on expectation of imminent death (71 of 75). Ethnic variability was noted among the 14 of 21 patients who refused withdrawal. Discussions for care restrictions were initiated almost exclusively by paediatricians (70 of 75). Diagnostic uncertainty (36% v 4.6%) and presentation as an acute illness were associated with the use of active treatment.

    CONCLUSIONS: Limitation of treatment is the most common mode of death in a developing country's PICU and active withdrawal is still not widely practised. Paediatricians in developing countries are becoming more proactive in managing death and dying but have to consider sociocultural and religious factors when making such decisions.

    AIM: Knowledge of the spectrum and frequencies of pediatric emergencies presenting to an emergency department (ED) of individual developing countries is vital in optimizing the quality of care delivered locally.

    METHODS: A prospective 6 wk review of all pediatric (< 18 y) attendees to an urban ED was done, with patient age, presenting complaints, diagnoses, time of arrival and disposition recorded.

    RESULTS: Complete data were available on 1172 patients, with an age range of 4 d to 18 y (mean +/- SD 6.9 +/- 5.6 y); 43% were aged < or = 4 y. The main presenting complaints were injuries (26.9%), fever (24%) and breathing difficulties (16.6%). The most common diagnosis was minor trauma (24.2%), with soft-tissue injuries predominating (80.6%). The other diagnoses were asthma (12.6%), upper respiratory infections (12.1%), other infections (12.1%) and gastroenteritis (11.8%). Equal proportions of patients were seen throughout the day. 25% of patients were admitted. Young age (< 1 y); presence of past medical history, general practitioner referrals, diagnosis of bronchiolitis and pneumonia were significantly associated with risk of admission.

    CONCLUSION: A wide spectrum of paediatric illnesses was seen in the ED, with an overrepresentation of young children. This supports the decision to have either a separate pediatric ED or paediatric residents on the staff. The training curricula should emphasize the management of pediatric trauma, infections and asthma. Alternatively, developing guidelines for the five most common presenting complaints would account for 82% of all attendees and could be directed towards all staff on the ED.

    AIM: To determine the epidemiology of rotavirus gastroenteritis in children admitted to an urban hospital in a developing country from South-East Asia.

    METHODS: Retrospective review of cases of acute gastroenteritis admitted to the children's ward of the University of Malaya Medical Centre, Kuala Lumpur, Malaysia, between 1996 and 1999.

    RESULTS: During the study period, 333 cases (24%) of 1362 stool samples, obtained from children admitted with acute diarrhoea, were positive for rotavirus. Acute gastroenteritis constituted 8.2%, and rotavirus infection 1.6% of all the paediatric admissions each year. Of the 271 cases analysed, 72% of the affected population were less than 2 years of age. Peak incidence of admissions was between January to March, and September to October. Dehydration was common (92%) but electrolyte disturbances, lactose intolerance (5.2%), prolonged diarrhoea (2.6%) and cow's milk protein intolerance was uncommon. No deaths were recorded.

    CONCLUSIONS: Rotavirus infection was a common cause of childhood diarrhoea that required hospital admission in an urban setting in Malaysia.

    OBJECTIVES: To determine the incidence and outcome of acute respiratory distress syndrome (ARDS) in children by comparing two commonly used definitions: the lung injury score and the American-European Consensus Conference definition. The causes and risk for developing ARDS were also studied.

    METHODS: Part prospective and retrospective analysis of 8100 consecutive hospital admissions from 1 June 1995 to 1 April 1997.

    RESULTS: Twenty one patients fulfilled the criteria for ARDS. Both definitions identified the same group of patients. The incidence was 2.8/1000 hospital admissions or 4.2% of paediatric intensive care unit admissions. The main causes were sepsis and pneumonia. Mortality was 13 of 21. Factors predicting death were a high admission paediatric risk of mortality (PRISM) score (30.38 v 18.75) and the presence of multiple organ dysfunction syndrome (92% v 25%).

    CONCLUSION: Both definitions identified similar groups of patients. The incidence in this population was higher than that reported elsewhere, but mortality and cause were similar to those in developed countries. Poor outcome was associated with sepsis, a high admission PRISM score, and simultaneous occurrence of other organ dysfunction.

    This is a report of 3 Chinese children with intestinal lymphangiectasia in Malaysia. Two children responded to a low fat diet and medium-chain triglyceride supplement. The third child has recurrent chylous ascites. None of the children has recurrent infections despite low CD4+ cells and low levels of IgG and IgA. Intestinal lymphangiectasia is a rare congenital disorder of the mesenteric lymphatic that leads to the obstruction of the lymphatics of the intestine and protein losing enteropathy. Restriction of dietary fat intake will usually result in remission. Recurrent chylous ascites is a problem and management can be difficult.

    The purpose of this study was to identify the early indicators of hemorrhage in severe dengue infections in 114 patients; 24 patients had severe hemorrhage and 92 had no hemorrhage. The platelet counts were not predictive of bleeding. The duration of shock (OR, 2.11; 95% CI, 1.13 to 3.92; P =.019) and low-normal hematocrit at the time of shock (OR, 0.72; 95% CI, 0.55 to 0.95; P =.020) were risk factors of severe hemorrhage.

    OBJECTIVE: To study the viral aetiology of lower respiratory tract infection (LRTI) in young Malaysian children.

    METHODOLOGY: A retrospective review was performed of LRTI patients aged less than 24 months who were admitted to the University Malaya Medical Centre between 1982 and 1997. Respiratory viruses in their nasopharyngeal secretion were identified by indirect immunofluorescence, viral culture, or both.

    RESULTS: A total of 5691 children were included in the study. The mean age was 8.6 +/- 6.6 months and the M:F ratio was 1.6:1. The most common diagnosis was pneumonia (52%) followed by bronchiolitis (45%) and croup (2%). Positive viral isolation rate was 22.0%. Respiratory syncytial virus (RSV) was the commonest virus isolated (84%), followed by parainfluenza virus (8%), influenza virus (6%) and adenovirus (2%). Patients with positive virus isolation were younger (7.8 +/- 6.2 vs 8.7 +/- 6.7 months, P = 0.0001) and were more likely to have bronchiolitis.

    CONCLUSION: Young Malaysian children admitted with LRTI had a 22% viral isolation rate and RSV was the commonest virus isolated.

    Objective: Lack of direct access to tertiary pediatric intensive care services in rural hospitals may be associated with poorer outcome among critically ill children. Inter-hospital transport by non-specialized teams may also lead to increased morbidity and even mortality. We therefore studied the outcome of children with different accessibility to tertiary pediatric care in Malaysia.

    Methods: We prospectively compared the Pediatric Risk of Mortality (PRISM II) adjusted standardized mortality ratio (SMR), unanticipated deaths and length of stay of 131 patients transported from rural hospitals (limited access) with 215 transferred from the casualty wards or other in-hospital wards (direct access) to a tertiary pediatric ICU.

    Results: The transported patients were younger than the in-hospital patients (median age 1.0 versus 6.0 months, p=0.000) and were more likely to have respiratory diseases. Other baseline characteristics did not differ significantly. Differences in access to tertiary intensive care from community hospitals was associated with an extended median length of stay (4.0 versus 2.0 days, p=0.000) but did not affect SMR (0.92 versus 0.84, rate ratio 1.09, 95% CI 0.57-2.01; p=0.348) or percentage of unexpected deaths (4.8% versus 2.8%, p=0.485). The adjusted odds ratio for mortality (1.7, 95% CI 0.7-4.3) associated with transfer was not statistically significant (p=0.248).

    Conclusions: The outcome of critically ill children transferred from community hospitals did not differ from that of those who develop ICU needs in the wards of a tertiary center, despite being transported by non-specialized teams. Outcome was not affected by initial inaccessibility to intensive care if the children finally received care in a tertiary center.
