Objectives: A child's admission into intensive care is a major cause of stress for parents. However among Malaysian parents, data concerning the perception of stress are virtually absent. Therefore we conducted a study to measure the reliability of the Malay version of Parental Stressor Scale: Pediatric Intensive Care Unit (PSS: PICU) in identifying sources of stress and to study factors that might influence their stress response.
Methods: Over a six-month period, one hundred and twelve parents were requested to answer the questionnaires twice either in Malay or English, a week apart. Spearman's correlation and Cronbach's alpha coefficient was used to assess the repeatability and internal consistency of the questionnaires.
Results: Ninety-four (83.9%) and seventy-one (75.3%) parents responded to the first and second administration of questionnaire respectively. All answered in the Malay language except for three. The correlation ranged from 0.50 to 0.71 with a total score of 0.76. The Cronbach's alpha coefficient ranged from 0.75 to 0.93, with total a score of 0.95.
Alteration in parental roles was the most stressful source of stress. Fathers, parents of children with higher PRISM score and parents with no previous admission into intensive care unit scored significantly higher in staff’s communication.
Conclusion: The Malay version of PSS: PICU is reliable in identifying sources of stress. Alteration in parental roles was the most stressful source of stress. Parents' gender, previous experience and severity of the child illness may influence their stress responses.
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.

Congenital chloride diarrhoea is a rare disorder mainly reported in Finland. A Malay child with congenital chloride diarrhoea presenting at six months of age with watery stools from birth and failure to thrive is reported.
The treatment preferences of 109 general practitioners (GPs) for childhood asthma were determined. Availability and adherence to clinical practice guidelines (CPG) for the treatment of childhood asthma was also assessed. Ninety eight (90%), 60 (55%) and 33 (30%) GPs considered nocturnal symptoms > 2 times/week, exercise induced wheeze and cough respectively as indications for preventer therapy. An oral preparation was preferred for relief medication [72 (66%) for 2-5 years, 60 (55%) for > 5 years]. An inhaled preparation was however preferred for preventer medication [60 (55%) for 2-5 years, 85 (78%) for > 5 years]. The oral form was more likely prescribed for asthmatic children 2-5 years (p < 0.001). Corticosteroids and ketotifen were the commonest inhaled and oral preventer treatment prescribed respectively. Only 36(33%) GPs have a CPG copy for reference. Children with asthma symptoms that require preventer therapy may not always be identified in general practice. The oral route remains important for asthma medication especially in young children. The accessibility to the CPG among GPs is disappointing.

Cystic fibrosis (CF) is a rare disease among Asians. Three Malay children with CF presenting with recurrent pulmonary symptoms, malabsorption and failure to thrive are reported. Problems in their management include availability of pancreatic enzymes, compliance to medications and climate factors.
Atopic dermatitis is the commonest skin disease in children, causing psychological, social and functional disability to them and their families. This study assessed the family impact and quality of life using the translated Malay version of The Dermatology Family Impact (DFI) and The Children's Dermatology Life Quality Index (CDLQI) questionnaires. Seventy-two children, aged between 6 months and 16 years attending the Paediatric Dermatology Clinic at the Paediatric Institute and the Dermatology Department, Hospital Kuala Lumpur participated in this study. Thirty-nine patients (54.2%) were males and 33 patients (45.8%) were females. The median age of the patients was 74 months (Q1 6, Q3 104 months). The median age of diagnosis was 22 months (Q1 1, Q3 36 months). The median disease duration was 44 months (Q1 3, Q3 65). The severity of eczema was assessed using the SCORAD severity index (maximum score = 83). The median SCORAD (European Task Force On Atopic Dermatitis) score was 36 (n = 72, SD = 16.2). The majority of patients in this study suffered from moderately severe eczema (n = 40, mean, SCORAD = 29.3) followed by severe eczema (n = 27, mean SCORAD = 54.3). The mildly affected patients formed the minority group (n = 5, mean SCORAD = 9.0). The family impact was shown to be greater in severe atopic dermatitis compared to moderate atopic dermatitis (Anova, p = 0.02). The children's quality of life impairment was also greater in severe atopic dermatitis compared to moderate atopic dermatitis (Anova p = 0.08). This study confirms that quality of life and family impact are related to the severity of atopic dermatitis.
This was a descriptive study to assess parents' knowledge of epilepsy in their children at the Klinik Pakar Pediatrik in Universiti Kebangsaan Malaysia from 1.1.93-31.6.93. Factors that influence the level of knowledge were examined. Our hypothesis was that the level of knowledge was low and level of education and social factors were important. Fifty consecutive parents were interviewed during the clinic appointments. The questionnaire consisted of 25 questions which had been used in a survey on epilepsy in Australia. In order to cater for the local population the questions were modified by adding new questions pertaining to local situation. The results showed that 90% (45/50) of parents were unaware of the type of epilepsy their children were suffering from. 50% (25/50) of parents knew the underlying cause of epilepsy of which 32% (8/25) attributed it to brain disease, 8% (2/25) to birth defects and 10% (3/25) to fever. Factors such as duration of epilepsy, parental education and racial differences between Malay and other races (Chinese, Indians) did not reach any statistical significance (p > 0.05). 80% of patients (30/50) were on monotherapy. However, 90% (45/50) of parents were unaware of their children's medications. 82% of parents (31/50) knew that the anti-convulsants would only control their children's convulsions. Only 10% (8/50) of parents knew the acute management of seizures. Wrong practices such as inserting spoons (5/50) or massaging their limbs (17/50) during an acute attack were still common. 70% of parents (35/50) attended the follow-up clinics hoping that their children's epilepsy would be cured. Parents with low economic status and of children with duration of epilepsy of less than five years had been coming to the clinic regularly. (p = 0.01 and p = 0.02 respectively). In conclusion, the overall knowledge of these parents was poor. In order to improve the management of epilepsy, it is necessary to educate parents with reading materials and effective educational packages.

The increasing prevalence of childhood asthma has become a concern among health practitioners. Effective management emphasizes long-term management and inhaled therapy has become the mainstay home management for children. However, proper utilization of medication is pertinent in improving control. Proper asthma education is mandatory in improving skills and confidence amongst parents. To assess the skills of using the metered-dose inhaler (MDI) with a spacer among asthmatic children before and after educational intervention and to analyse any difficulties which may occur amongst the participants in executing the assessment steps. A cross-sectional clinic based study involving 85 parents and children with asthma. A standardized metered-dose inhaler-spacer checklist of eight steps of medication usage and five steps of cleaning the spacer were used as the assessment tools for pre and post intervention. The performance on using the inhaler-spacer and spacer cleaning knowledge pre and two months post intervention was evaluated. One point was given for each correct step and zero points for incorrect answers/steps. The mean score for skills of inhaler technique improved significantly after educational intervention (3.51 to 6.01, p < 0.0001) as did the mean score for parental knowledge of spacer cleaning technique (1.35 to 3.16, p 0.001). Analysis showed only a limited improvement even after an educational session in three steps of inhalation technique: step 5 (23.5%/69.4%), step 6 (28.2%/68.2%) and step 7 (25.9%/61.2%). Parents with asthmatic children had poor skills in utilizing their children's medication. A short-term educational intervention was able to improve overall knowledge and skill but certain skills need more emphasizing and training.

Congenital upper airway obstruction is a relatively rare but important cause of major respiratory problems in the neonatal period. Vocal cord paralysis is the second most common cause of congenital airway obstruction presenting with neonatal stridor. It is often the reason for the failure of neonates to wean from the respiratory support. A retrospective analysis of medical record review was conducted. There were seven paediatric patients diagnosed with bilateral vocal fold paralysis in the past three years, of which five were recently diagnosed. All patients underwent flexible with/without rigid bronchoscopes to confirm the diagnosis. This case series highlight our experience in managing the problem of bilateral vocal cord paralysis in the paediatric population, with particular emphasis on their clinical presentations, associated complications and both upper and lower airway abnormalities. The management options and outcome of these patients will also be discussed.
We report a 17-year-old Malay boy with cystic fibrosis who over a 14-month period experienced worsening respiratory symptoms and deteriorating lung function. Burkholderia pseudomallei was eventually isolated from his sputum. He improved clinically following treatment for meliodosis and his lung function returned to normal.
Interstitial lung disease (ILD) is very rare in children. In the majority of cases the aetiology is unknown. Very little is known about the clinical course of this condition in children. Prognosis may be influenced by sex, age of onset of symptoms, radiographic features, presence of right ventricular hypertrophy and histopathology. We report our experience in managing four children with interstitial lung disease. All these children presented in early infancy with cough, respiratory distress, cyanosis and failure to thrive. Three of these children had finger clubbing and right ventricular hypertrophy. All patients received oral steroids. Chloroquine was added in two patients who showed no response. A trial of oral cyclophosphamide was started in one patient who failed with both drugs. One child is oxygen independent while another is on home oxygen therapy. The other two patients eventually died.
Objectives: (a) To examine the intra-observer reliability of the Malay language versions of two international respiratory questionnaires i.e. the International Study of Asthma and Allergy in Children (ISAAC) and the American Thoracic Society (ATS) questionnaires, and (b) using the more reliable of these questionnaires, to estimate the prevalence of asthma and allergy related symptoms in an ethnically homogenous inner city community in Kuala Lumpur.
Methods: The study was conducted among 7 to 12 year old school children of Malay ethnic origin living in an inner city area of Kuala Lumpur. The sample consisted of 787 children attending the only primary school in the area. The Malay versions of both questionnaires were administered twice, one month apart, and were completed by parents. Agreement between the first and second responses to the same questions were assessed by Cohen’s kappa. Kappa values <0.4 were indicative of poor intra-observer reliability, 0.4-0.59 moderate reliability, 0.6-0.79 good reliability and >0.79 excellent reliability.
Results: 77.9% and 36.3% of parents responded to the first and second administrations of the questionnaires respectively. Kappa values of >0.4 were obtained in 15/16 (93.8%) and 17/27 (63.0%) questions of the ISAAC and ATS questionnaires respectively. Excellent kappa values were obtained in 4/16 (25%) questions of the ISAAC questionnaire versus only 1/27 (3.7%) questions of the ATS questionnaire. From the ISAAC questionnaire, all questions on wheeze had good reliability while those on asthma had excellent reliability. Questions on allergic symptoms had poor to moderate reliability. In contrast, from the ATS questionnaire, questions on wheeze had moderate reliability while questions on asthma were excellent reliable. Questions on allergic symptoms had moderate to good reliability while those on cough, phlegm and bronchitis had poor reliability.
According to the ISAAC questionnaire the prevalence of ever wheeze, wheeze in the last 12 months, ever asthma and wheeze with exercise in the last 12 months was 12.5%, 6.6%, 10.3% and 5.9% respectively. The prevalence of ever sneeze or runny nose, sneeze or runny nose in the last 12 months, watery eyes in the last 12 months and ever eczema was 15.2%, 11.1%, 4.4% and 8,5% respectively.
Conclusions: The translated ISAAC questionnaire was more reliable than the translated ATS questionnaire. Asthma and related symptoms were common among Malay school children in inner city Kuala Lumpur.
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.
Objectives: This was a cross sectional study conducted in the Paediatric Institute among infants and children with chronic respiratory symptoms with the following objectives: i) to determine the prevalence of gastro-oesophageal reflux in children with persistent respiratory symptoms, ii) to identify the clinical predictors of GOR (Gastro-oesophageal reflux) in children with persistent respiratory symptoms and iii) assess the validity of abdominal ultrasound, barium oesophagogram and chest radiograph in diagnosing GOR in these patients.
Materials and Methods: Forty-four patients were recruited over a period of six months. All the presenting symptoms were identified. The patients were subjected to chest radiograph, abdominal ultrasound, barium oesophagogram and 24-hour pH oesophageal monitoring.
The predictive validity of clinical symptoms, chest radiograph, abdominal ultrasound and barium oesophagogram were assessed. Twenty-four hours oesophageal pH was the gold standard to diagnose GOR.
Results: The mean age of patients was 9.1 months (1-58 months). Thirty-one patients (70.5%) were confirmed to have GOR by pH study. Respiratory symptoms alone were not useful to predict GOR. Cough had the highest sensitivity of 51.6%. stridor, wheeze and choking each had a specificity of 76%. Wheeze, vomiting, choking and stridor were identified to have high specificity (90-100%) in diagnosing GOR when any two symptoms were taken in combination.
Collapse/consolidation was the commonest radiological abnormality but had low sensitivity (35.5%) and specificity (53.8%). However hyperinflation on chest radiograph had a specificity of 92.3% with positive predictive value at 80% in diagnosing GOR. Barium oesophagogram has low sensitivity (37.9%) and moderate specificity (75%) in diagnosing GOR in children with respiratory symptoms.
Abdominal ultrasound was a valid mode of diagnosing GOR when there were three or more reflux episodes demonstrated during the screening period with a specificity of 90.9%. However the sensitivity was low ie 20-25%. The specificity increased to 90-100% when two positive tests were taken in combination (abdominal ultrasound and barium oesophagogram). However the sensitivity remained low (10-20%). Chest radiograph did not improve the predictive value when considered with the above tests. Combination of clinical symptoms were useful as clinical predictors of GOR. In the absence of a pH oesophageal monitoring, a combination of barium oesophagogram and ultrasound may be helpful in diagnosing GOR.
The objective of this study was to measure the knowledge of childhood asthma among medical students and paramedics. A previously validated questionnaire about childhood asthma was completed by 281 of 314, third and fifth year medical students at Universiti Kebangsaan Malaysia, Kuala Lumpur. Their knowledge of asthma was assessed during the first and last weeks of their paediatric rotation. A similar questionnaire was completed by 23 of 60 paramedics from various medical disciplines in Hospital Kuala Lumpur. They had attended a two-day seminar on respiratory diseases and their knowledge was assessed prior to and six weeks after the seminar. On the initial assessment the mean score for the final year medical students was 24.5, third year medical students 20.9 and paramedics 18.3. After intervention their mean scores increased significantly to 26.3 (p < 0.0001), 24.6 (p < 0.0001) and 21.3 (p < 0.0001). After intervention, the final year medical students improved significantly in all questions except in the management of acute asthma. Post intervention, third year medical students showed a significant increase in knowledge pertaining to symptomatology, pathophysiology, trigger factors and prophylactic drugs used in asthma management. Although the knowledge of paramedics improved post intervention, they had major deficiencies in knowledge about pathophysiology, trigger factors, preventive and acute asthma therapy, side effects of asthma treatment as well as clinical scenarios. Improvement after intervention was only seen in six of the 31 questions. This study demonstrated an increase in knowledge about childhood asthma among medical students and paramedics after a short intervention.
We report a case of left pulmonary artery sling in a child who also had duodenal atresia. He was admitted for respiratory failure requiring prolonged respiratory support due to a bronchiolitis-like illness at two months of age. Diagnostic procedures confirmed the presence of left pulmonary artery sling. He had a corrective procedure which relieved the compression. However postoperatively he had intermittent episodes of severe bronchospasm in addition to a persistent airway obstruction. Finally one such episode of severe bronchospasm did not respond to medical and resuscitative therapy and the baby succumbed. To our knowledge no case of left pulmonary artery sling has been described previously in a Malaysian child. This case also highlights the postoperative airway problems that may be encountered.
Respiratory symptoms in children may be associated with underlying gastro-oesophageal reflux (GOR). We reviewed the case notes of 20 children who presented to us from June 1993 to June 1994 with respiratory symptoms and GOR. The patients consisted of 16 Malays, two Chinese and two Indians with equal number of males and females. Their age at diagnosis was less than one year in 17 patients. The earliest age at presentation was at the third day of life. All patients had major respiratory manifestations i.e. recurrent wheezing, recurrent cough and pneumonia. In addition, three patients had stridor and six patients had apparent life threatening episodes (ALTE). Fourteen patients required ventilation because of respiratory failure. Diagnosis of GOR was based on clinical grounds supported by barium oesophagogram in seven patients and ultrasound examination in 11 patients. Eight patients were fundoplicated because of ALTE and recurrent severe bronchospasm. On follow up, 14 patients had hyperactive airways requiring inhaled bronchodilator and steroid therapy.
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.
Cystic fibrosis (CF) is an autosomal recessive disease commonly found among the Caucasian population. The availability of sweat test and with increasing experience have made it possible to diagnose more cases of CF. Our first case of CF was diagnosed 16 years ago and to date we have managed sixteen cases of CF. Sixteen children were diagnosed with CF in our units at the Paediatric Institute and University Malaya Medical Centre (UMMC). They were referred with either one or all of the following symptoms: i) recurrent pneumonia, ii) bronchiectasis, iii) failure to thrive, iii) malabsorption or iv) history of meconium ileus obstruction during the neonatal period. When the clinical features suggested strongly of CF, sweat tests will be performed in duplicates and considered positive when the sweat chloride or sweat sodium was more than 60 mmol/l for both results. Seventy- two hours fecal fat excretion or stool for fat globule was performed to document malabsorption. From the year 1987 to 2003, 16 patients were confirmed to have cystic fibrosis in Malaysia by positive sweat tests. Thirteen patients were diagnosed in Paediatric Institute while the remaining three were diagnosed in UMMC. On follow-up two patients died due to severe bronchopneumonia at the age of two years old. Although once considered rare, CF should now be considered in any children with clinical presentations of recurrent chest infections, bronchiectasis, in the presence or absence of malabsoption stmptoms and in neonates with meconium ileus obstruction.
Summary: Home oxygen therapy programme is new in Malaysia. This programme enables children with respiratory insufficiency to be discharged home early.
Materials and Methods: Long term oxygen therapy was initiated using an oxygen concentrator in patients who i) remained hypoxic while breathing room air, ii) experienced desaturations of more than 20% during sleep as seen in patients with severe laryngomalacia and obstructive sleep apnoea syndrome and iii) had pulmonary hypertension with or without polycythemia. The median with first and third quartile values are presented for the quantitative variables.
Results: A total of 71 patients mainly children with bronchopulmonary dysplasia (BPD) (32) and bronchiolitis obliterans (12) were discharged home on this programme. The median age at which home oxygen was initiated in children with BPD was 5.0 (Q1:2 Q3:8) months. The median total duration of oxygen requirement for BPD was 8.0 (Q1:5, Q3:12) months. The median duration of home oxygen dependency was 3.5 (Q1:3, Q3:6) months. However children with bronchiolitis obliterans required longer duration of oxygen therapy compared to children with BPD i.e. median duration of 28 months (Q1:14.5 Q3:66). In other respiratory conditions the mean duration of supplemental oxygen varies some of which may be life long.
Conclusions: This paper has shown the importance of home oxygen program in children with respiratory disorders. It has significantly shortened hospital stay and thus saves hospital costs and prevents prolonged separation from the family.
