Abstract

Background Chronic inhalation of air pollutants may causebronchoconstriction, bronchiolitis, and edema of airway, thus alterlung volume. To measure the lung volume, a simple lung functiontest, the peak expiratory flow rate (PEFR), can provide a feature oflung volume in liters/minute.Objective The purpose of this study was to measure PEFR val-ues of primary school children in a high air pollution level area(Medan) and compare the results with the PEFR values of those ina low air pollution level area (Tebing Tinggi).Methods A cross sectional study was conducted on primary schoolchildren (10-12 years of age) during May-July 2000 in Medan andTebing Tinggi. Data were obtained by questionnaires. Physical ex-amination included age, sex, height, weight, and PEFR value. PEFRvalues were measured by Mini Wright peak expiratory flow meter(MPFM) from three blows. The highest volume was taken as thePEFR value. Statistical analysis was done by t-test and p<0.05was considered significant.Results There were 212 primary school children eligible for thisstudy; 107 came from the high air pollution level area and 105from the low air pollution level area. The PEFR values did not dif-fer significantly between the two groups (p>0.05)Conclusion PEFR values in a high air population level area werenot statistically different compared with those in low air pollutionlevel area

Abstract

Objective To investigate the clinical aspects and result of Man-toux test in superficial lymphadenitis caused by Mycobacteriumtuberculosis (MTB) compared to that caused by non-MTB organ-isms.Methods This was a cross sectional study conducted on 86 pa-tients aged between 3 months and 14 year-old with enlargementof the superficial lymph nodes, 43 with tuberculosis superficial lym-phadenitis (TSL) and 43 with non-tuberculosis superficial lymphad-enitis (NTSL). The diagnoses of TSL and NTSL were confirmed byhistopathological examination. Clinical symptoms and Mantoux testwere examined in this study.Results In the TSL group, most children (70%) were in the age of>5-14 year-old, while in the NTSL, most (46%) were 1-5 years old.The most frequent chief complaint in the TSL group was fever(37%), while in the NTSL group, cough (49%) (p=0.004). Failure tothrive and loss of appetite were more frequently found in the TSL(70% and 35%) compared to the NTSL group (0 and 3%) (p=0.004).Most enlarged nodes in TSL were multiple (67%), while in NTSL,solitary (72%) (p<0.001). There were no differences in the locationand distribution of enlarged nodes between the two groups. Thirty-one (72%) children in the TSL group had positive Mantoux test,while in the NTSL group were only 2(5%) (p<0.001).Conclusions Most children with TSL had fever as the chief com-plaint while those with NTSL had cough. Children with TSL hadfailure to thrive, loss of appetite, multiple nodes, and positive Man-toux test more frequently compared to NTSL ones
