  1. Fulltext Validity and reliability of the SF-36: the Malaysian context
    Sararaks S, Azman AB, Low LL, Rugayah B, Aziah AM, Hooi LN, et al.

    PMID: 16114157
    Results of construct validity and reliability of the SF-36 are described, based on data from a multi-centre study on asthmatics and a population based survey. Questionnaire refinement was carried out between the two studies. Quality of data was good, with all items having less than 0.5% missing values. Floor and/or ceiling effects were observed for REE, REP, PF and SF. For scaling assumptions, correlations between each items and its hypothesized scale were all above 0.50, except for one item in PF. and for both items in SF. Item discriminant validity was an issue for items in VT, SF and MH scales. Cronbach's as for all scales exceeded the recommended 0.70 level, except for SF. Only one latent dimension was identified in principal component analysis, and only 52-53% of variance accounted for. As expected, PF shows high correlations with the physical component while MH was highly correlated with the mental component. Contrasting findings in the loadings of other scales were observed in the asthma data. Age, disease severity and presence of self-reported handicap/disability significantly affect PF, while MH demonstrates no obvious pattern with declining age. In essence, the Malay version of SF-36 could be used in Malaysia, with its generally acceptable internal consistency and validity. The caveat is in the call for additional domains of importance to Malaysians that is not covered by the instrument, and in the caution to be employed when using and construing the instrument.

    Eosinophilic inflammation in the airways is important in the pathogenesis of childhood asthma. Serum eosinophilic cationic protein (ECP), a marker of eosinophil activation was measured in 20 asthmatic children and 19 non-asthmatic controls. There was no difference in the socio-demography, passive smoke exposure, urinary cotinine levels and family history of asthma between the 2 groups. The median serum ECP in asthmatic children was 27.0 mcg/L (IQ1 8.8, IQ3 59.0); which was higher than in non-asthmatic controls [5.9 mcg/L (IQ1 3.0, IQ3 11.9), p=0.002]. An elevated serum ECP level can be helpful as supportive evidence in the diagnosis of bronchial asthma in Malaysia children.

    Asthma can place considerable restrictions on the physical, emotional and social aspects of the lives of patients. The assessment of quality of life aims to provide a means of measuring the impact of this disease on patients' lives, from the patients' perspective. A cross sectional multi-centre study was conducted in six government hospitals throughout the country. Self-administered SF-36 was used, and clinical information obtained through interviews and examination. 1612 asthmatics responded. Females constituted 63% of the respondents; mean age was 40.9 years; Malays were the majority ethnic group, while 70.8% had secondary level education and 53.7% were employed. Half had suffered from asthma for at least 13 years, while 46.8% and 23.6% have moderate and severe disease respectively. Quality of life was affected by severity of disease. Asthmatics, had a significantly poorer quality of life than the general US population. Severe asthma disease was associated with a compromised quality of life, similar to that of COPD.

    Norzila MZ, Haifa AL, Deng CT, Azizi BHO
    Med J Malaysia, 2000 Mar;55(1):33-9.
    PMID: 11072488 MyJurnal
    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.

    Norzila MZ, Hasanah I, Deng CT, Azizi BHO
    Med J Malaysia, 2000 Sep;55(3):324-30.
    PMID: 11200712
    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.

    PMID: 9241894
    The prevalence and severity of asthma, rhinitis and eczema in Kelantanese schoolchildren were determined as part of an international study of the epidemiology of asthma and allergic diseases. The international study of asthma and allergies in childhood (ISAAC) written questionnaire was administered to 7055 schoolchildren from February 1995 to August 1995. The respondents were parents or guardians of 5- to 7-year-old children (n = 3939), and schoolchildren aged 12-14 years (n = 3116). The ISAAC video questionnaire (AVQ3.0) was shown to children aged 12-14 years after the written questionnaire. The overall prevalences of 'ever wheezed' and 'wheezing in last 12 months' were 9.4 and 6.0% respectively. The prevalence of 'ever diagnosed with asthma' was 9.4%. Both 'ever wheezed' and 'wheezing in the last 12 months' were significantly higher in 12- to 14-year-old children than in 5- to 7-year-old children, with P values of 0.0006 and 0.014 respectively. No gender differences in the prevalences were observed. For the complete study group, 4.7% of children had sleep disturbed by wheezing but only 1.1% had a severe attack limiting speech in the preceding 12 months. Sleep disturbance was more common in the 12- to 14-year-old children than in 5- to 7-year-old children (P = 0.006). There was no difference between the age groups for severe attacks limiting speech. The overall prevalence of rhinitis and eczema symptoms were 27 and 12%, respectively. The prevalence of rhinitis in the 12-14 year age group (38.2%) was significantly higher (P < 0.0001) than in the 5-7 year age group (18.2%). The prevalence of eczema in the 5-7 year age group (13.7%) was significantly higher (P = < 0.0001) than in the 12-14 year age group (9.9%). These prevalence data are comparable with previous reports in Malaysian children, but are considerably lower than those reported for most developed countries.

    PMID: 1387454
    To assess the prevalence of skin test sensitivity among asthmatic patients in Malaysia, skin prick tests for allergy in 134 adult asthmatic patients and 120 control subjects were done. 90% of asthmatic patients had positive skin test to at least one allergens as compared to 78% of the controls. House dust mite was the most frequent allergen to which the subjects had positive reactions. Sixty-four percent of the asthmatic patients had associated rhinitis. There was no significant difference in the skin test sensitivity between asthmatic patients with associated rhinitis and those without.

    PMID: 9579609
    As future health care providers medical students should acquire an adequate knowledge of bronchial asthma before graduation from medical school. The aim of this study was to assess whether knowledge about childhood asthma increased during the medical course. The 590 medical students enrolled in the School of Medical Sciences, University of Science Malaysia during the 1995/96 session were studied utilizing a validated questionnaire. There was a significant increase in the mean total scores from 11 (95% CI 10.5-11.6) in Year 1 to 23.4 (95% CI 22.9-24) in Year 5. Questions about symptoms of asthma, pathogenesis of airway narrowing during acute exacerbations, preventive and reliever medications, side effects of steroids, addiction to asthma drugs and assessment of severity revealed a progressive increase in knowledge over the five years. Among 5th year medical students 44.6% named infection and 65.1% named exercise as two common triggers of childhood asthma; only 30.1% could name two prophylactic drugs for asthma. Although the asthma knowledge of medical students increased progressively during the five year curriculum, their knowledge regarding trigger factors and preventive medications were deficient. As childhood asthma affects some 10% of Malaysian children its importance requires greater emphasis in the medical curriculum.

  11. Respiratory symptoms and asthma in primary school children in Kuala Lumpur
    Omar AH
    Acta Paediatr Jpn, 1990 Apr;32(2):183-7.
    PMID: 2116069
    In a cross-sectional study of 7 to 12-year-old primary school children in Kuala Lumpur, the prevalence of chronic cough and/or phlegm, persistent wheeze, and doctor-diagnosed asthma were 8.0%, 8.0% and 8.7%, respectively. The prevalence of asthma (defined as persistent wheeze and/or doctor-diagnosed asthma) was 13.8%. 4.3% experienced at least one episode of chest illness that resulted in inactivity for at least 3 days in the previous year. The mean age of commencement of symptoms in the doctor-diagnosed asthma group was 2.75 years. The prevalence of chronic cough and/or phlegm and persistent wheeze were highest among Indian children (p less than 0.05). More Malays had been diagnosed as having asthma than the other ethnic groups but the differences were not statistically significant. The patients' fathers' low levels of education were associated with chronic cough and/or phlegm (p less than 0.05) but not with other complaints. Asthma was significantly more common among boys than girls. No age differences were noted. Further analysis showed that persistent wheeze and doctor-diagnosed asthma were associated with increased likelihood of other respiratory illnesses or doctor-diagnosed allergy before the age of 2 years.

    Zulkifli A, Kamal AA
    Med J Malaysia, 1980 Dec;35(2):164-5.
    PMID: 7266412
    This study was proposed to identify specific radiological appearances in Malaysian patients with bronchial asthma. All consecutive patients, seen in the Medical Unit, Universiti Kebangsaan Malaysia between 1976 and 1979, satisfying the American Thoracic Society [1962] criteria for bronchial asthma formed the subjects of this study. Analysis of 207 patients led to the following conclusion. There are specific radiological changes present in a proportion of bronchial asthmatics during the acute episode. These changes are more frequent in the younger age group and in those in which the age of onset are early, The duration of asthma seems to have some bearing to the radiological changes.

    Curr Allergy Asthma Rep, 2016 10;16(10):70.
    PMID: 27613653 DOI: 10.1007/s11882-016-0650-5
    PURPOSE OF REVIEW: The development of biological therapies has rapidly progressed during the last few years, and major advances were reported for the treatment of allergic diseases, such as atopic dermatitis, allergic rhinitis, urticaria, food allergy, and asthma. Here, we review biologicals targeting the type 2 immune response involving Th2 cells, type 2 innate lymphoid cells, natural killer T cells, mast cells, basophils, and epithelial cells, such as IL-4, IL-5, IL-13, IL-31, tumor necrosis factor alpha (TNF-α), and thymic stromal lymphopoietin (TSLP).

    RECENT FINDINGS: The biologicals that have been currently approved for asthma are omalizumab targeting IgE and reslizumab and mepolizumab targeting interleukin (IL)-5. Many other monoclonal antibodies are currently in various phases of clinical development. The new biological therapies for allergic diseases will eventually be tailored to the endotypes of these diseases and the identification of novel biomarkers. Further development of novel biologicals for the treatment of allergic diseases and asthma will be possible upon improved understanding of mechanisms of allergic diseases. Accordingly, further refinement of endotypes of allergen-specific and non-specific type 2 immune response and related inflammatory mediators is needed for optimal treatment of allergic diseases.

    Singapore Med J, 2003 Mar;44(3):131-5.
    PMID: 12953726
    A survey was carried out among primary school teachers in the district of Kota Bharu, Malaysia to assess the level of knowledge on asthma and its management. Our findings revealed that primary school teachers were less informed about the management and treatment of asthma. They were relatively more knowledgeable about the causes and symptomatology of asthma. The majority of respondents had misunderstanding regarding the effect of rain, smoking and cold weather on asthma. It is important that teachers should be able to recognise symptoms of an asthmatic attack or take the necessary precautions to avoid such an attack. Many teachers agreed on the need to have an asthma education programme in their teaching curriculum.

  16. Fulltext The value of routine chest radiographs in acute asthma admissions
    Ismail Y, Loo CS, Zahary MK
    Singapore Med J, 1994 Apr;35(2):171-2.
    PMID: 7939814
    We reviewed 116 chest radiographs done in 70 adult asthmatic patients who were admitted to the Hospital Universiti Sains Malaysia from January to December 1989. The chest radiographs were abnormal in 23% of cases. Twelve percent showed hyperinflation and 7% had pneumonia. Eight patients diagnosed clinically to have pneumonia had normal chest radiographs. Seven patients had radiographic findings of conditions which were unsuspected clinically. These included two cases of pneumonia, one case each of fibrosing alveolitis, pneumothorax, pneumomediastinum, mitral stenosis with left ventricular failure and right pleural effusion. In conclusion, we found that significant chest radiograph abnormalities in adult patients admitted for asthma were uncommon although chest radiographs were helpful in detecting complications or coincidental conditions. Chest radiograph is therefore an important investigation in adult asthmatic patients who are admitted. However, considering the cost and the risk of radiation, it should be done only in selective cases rather than as a routine procedure.

    INTRODUCTION: Several risk factors found to be associated with postoperative complications and cancer surgery, which carry a significant morbidity risk to cancer patients. Therefore, prehabilitation is necessary to improve the functional capability and nutritional status of a patient prior to surgery, so that the patient can withstand any postoperative activity and associated deterioration. Thus, this study aims to assess the effectiveness of prehabilitation interventions on the functional status of patients with gastric and oesophageal cancer who underwent esophagectomy and gastrectomy.

    MATERIAL AND METHODS: An interventional study was carried out among oesophageal and gastric cancer patients who had undergone surgery at the National Cancer Institute of Malaysia. The prehabilitation process took a maximum of two weeks, depending on the patient's optimisation before surgery. The prehabilitation is based on functional capacity (ECOG performance status), muscle function (handgrip strength), cardio-respiratory function (peak flow meter) and nutritional status (calorie and protein). Postoperative outcomes are measured based on the length of hospital stay, complications, and Clavien-Dindo Classification.

    RESULTS: Thirty-one patients were recruited to undergo a prehabilitation intervention prior to gastrectomy (n=21) and esophagectomy (n=10). Demographically, most of the cancer patients were males (67.7%) with an ideal mean of BMI (23.5±6.0). Physically, the majority of them had physical class (ASA grade) Grade 2 (67.7%), ECOG performance status of 1 (61.3%) and SGA grade B (51.6%). The functional capacity and nutritional status showed a significant improvement after one week of prehabilitation interventions: peak expiratory flow meter (p<0.001), handgrip (p<0.001), ECOG performance (p<0.001), walking distance (p<0.001), incentive spirometry (p<0.001), total body calorie (p<0.001) and total body protein (p=0.004). However, those patients who required two weeks of prehabilitation for optimization showed only significant improvement in peak expiratory flow meter (p<0.001), handgrip (p<0.001), and incentive spirometry (p<0.001). Prehabilitation is significantly associated postoperatively with the length of hospital stay (p=0.028), complications (p=0.011) and Clavien-Dindo Classification (p=0.029).

    CONCLUSION: Prehabilitation interventions significantly increase the functional capacity and nutritional status of cancer patients preoperatively; concurrently reducing hospital stays and complications postoperatively. However, certain cancer patients might require over two weeks of prehabilitation to improve the patient's functional capacity and reduce complications postoperatively.

    PMID: 27099660 MyJurnal
    Juvenile recurrent respiratory papillomatosis (JRRP) is a rare condition. The varied presentation of this condition predisposes to misdiagnosis and potential life-threatening airway obstruction. In this paper, we have reported a case of JRRP presenting as severe respiratory distress and consequently mistreated as asthmatic attack culminating in a near fatal acute airway obstruction.

    J Asthma, 1995;32(6):413-8.
    PMID: 7592244 DOI: 10.3109/02770909409077752
    We performed a hospital-based study to examine a hypothesis that indoor air pollution was associated with acute asthma in young children living in Kuala Lumpur City. A total of 158 children aged 1 month to 5 years hospitalized for the first time for asthma were recruited as cases. Controls were 201 children of the same age group who were hospitalized for causes other than a respiratory illness. Information was obtained from mothers using a standardized questionnaire. Univariate analysis identified two indoor pollution variables as significant factors. Sharing a bedroom with an adult smoker and exposure to mosquito coil smoke at least three nights in a week were both associated with increased risk for asthma. Logistic regression analysis confirmed that sharing a bedroom with an adult smoker (OR = 1.91, 95% CI 1.13, 3.21) and exposure to mosquito coil smoke (OR = 1.73, 95% CI 1.02, 2.93) were independent risk factors. Other factors independently associated with acute asthma were previous history of allergy, history of asthma in first-degree relatives, low birth weight, and the presence of a coughing sibling. There was no association between asthma and exposure to kerosene stove, wood stove, aerosol mosquito repellent, type of housing, or crowding. We conclude that indoor air pollution is an avoidable factor in the increasing morbidity due to asthma in children in a tropical environment.
