OBJECTIVE The purpose of this study was to evaluate the variation in tonsil size and prevalence of asymmetric tonsils in 4- to 17-year-old schoolchildren and the relationships between tonsillar hypertrophy and frequent tonsillitis, frequent fever, and sleep-related symptoms observed by parents. DESIGN Cross-sectional study. SETTING Six daycare centres, four primary schools, and four high schools. METHODS Questionnaire and physical examination. MAIN OUTCOME MEASURES The size of the tonsils was evaluated and scored on a 4-point scale. The interrelationships between tonsillar hypertrophy and other studied symptoms were examined. RESULTS In the study, the parents of 1784 children, consisting of 803 (45%) boys and 981 (55%) girls, completed the questionnaires. The prevalence rates of snoring, habitual snoring, observed apnea, and habitual observed apnea were 24.6%, 4.1%, 3.8%, and 0.9%, respectively. The results of tonsil scoring were grade 1, 62.7%; grade 2, 28.4%; grade 3, 3.3%; and grade 4, 0.1%. The prevalence rate of grade 1 tonsils was increasing, whereas the prevalence rates of grade 2 and 3 tonsils were decreasing with increasing age. Tonsil size peaked in 4- to 8-year-old children. The prevalence rates of tonsillar hypertrophy and asymmetric tonsils were 3.4% and 1.7%, respectively. Tonsillar hypertrophy was found to be significantly associated with male gender, a history of frequent tonsillitis, a history of frequent fever, often or always snoring, and often or always observed apnea. CONCLUSIONS A tonsil size curve was developed in 4- to 17-year-old schoolchildren. Children aged 4- to 8 years with oropharyngeal symptoms and particularly male gender should undergo consultation with otorhinolaryngology and pediatric pulmonology physicians for the evalution of adenotonsillar tissue.

BACKGROUND Allergic rhinitis (AR) is a global health problem affecting many people from childhood to adulthood. The aim of this study was to evaluate the prevalence of AR and related symptoms, and to assess the risk factors, dietary habits and the Mediterranean diet affecting AR. METHODS In a cross-sectional study design, 9991 children, aged 13-14 years in 61 primary schools in 32 districts of Istanbul were evaluated. The prevalence of AR symptoms among the children was evaluated using the ISAAC protocol. RESULTS In our study, total of 10,984 questionnaires were distributed to 13-14yr-old schoolchildren to 61 schools in 32 district of Istanbul and 9991 questionnaires were suitable for analysis with an overall response of 91.7%. The rates of lifetime rhinitis, rhinitis in last 12 months and lifetime doctor diagnosed AR prevalence were 53.5%, 38.3% and 4.5%, respectively. The variation among districts in the prevalence of doctor diagnosed AR was very high. The highest prevalence was about 10 times higher than in the district with the lowest prevalence (range: 1.4-14.5) of Istanbul. A family history of atopy, mother with a university degree, presence of cat at home during last 12 months and adenoidectomy were significant for increased doctor diagnosed AR risk. Additionally, although fish and other sea foods, fermented drinks made from millets and various seeds, animal fats and butter were independent risk factors for doctor diagnosed AR, fish oil and hamburger were protective foods for doctor diagnosed AR. The MD was not associated with the prevalence of doctor diagnosed AR. CONCLUSIONS This study shows that that there are wide variations for the prevalence of AR related symptoms in 13-14yr-old schoolchildren among districts of Istanbul in Turkey. Socio-economical, environmental factors, some dietary habits, but not Mediterranean diet may affect the prevalence of AR.

OBJECTIVES To assess the time trends and possible risk factors associated with allergic rhinitis symptoms in schoolchildren from Denizli, Turkey. METHOD Two identical cross-sectional surveys were performed in the 13- to 14-yr age group at intervals of six years using ISAAC questionnaire. Possible risk factors were also asked and the children completed questionnaires by self. RESULTS A total of 4078 children (response rate 75%) in the 2008 and 3004 children (response rate, 93.8%) in 2002 were included. The lifetime prevalence of rhinitis, 12-month prevalence of rhinitis, prevalence of associated itchy eye in the previous 12 months and doctor diagnosed allergic rhinitis prevalence were increased from 34.2% to 49.4% (POR=1.87, 95% CI=47.8-50.9 and p ≤ 0.001), from 23.5.0% to 32.9% (POR=1.59, 95% CI=31.4-34.3 and p ≤ 0.001), from 9.6% to 14.9% (POR=1.64, 95% CI=13.8-16.0 and p ≤ 0.001), and from 4.3% to 7% (POR=1.67, 95% CI=6.2-7.8 and p ≤ 0.001) respectively. Severe interference with daily activity in the previous 12 months did not change. In multivariate analysis, history of family atopy, stuffed toys, high annual family income, presence of allergy in mother, father and accompaniment of children to their parents after school hours in textile industry were found as risk factors in 2008 study. CONCLUSION The prevalence of allergic rhinitis increased significantly in 2008. Family history of atopy, stuffed toys, high annual family income and accompaniment of children to their parents in textile industry were found as risk factors for doctor diagnosed allergic rhinitis.

BACKGROUND The prevalence of allergic rhinitis and other allergies has risen worldwide. Dietary habits are considered to be among the potential risk factors. The aim of this study was to evaluate the prevalence of allergic rhinitis and its relationship with dietary habits and other risk factors among 6 to 7-year-old Turkish schoolchildren. METHODS In this cross-sectional study, a total of 11483 children aged 6-7 years were surveyed. The prevalence of symptoms of allergic rhinitis was assessed using the ISAAC protocol. Dietary information was collected using a food frequency questionnaire. RESULTS Of them, 9875 (50.7% M 49.3% F) questionnaires were appropriately completed. The prevalence rates of lifetime rhinitis, current rhinitis, current rhinoconjunctivitis and physician-diagnosed allergic rhinitis, were 44.3%, 29.2%, 8.5% and 8.1%, respectively. Consumption of rice, and cereals ≥3 times per week showed protective effect on physician-diagnosed allergic rhinitis (aOR = 0.53, 95% CI = 0.32-0.87 and aOR = 0.58, 95% CI = 0.36-0.92). Eating pasta, and chocolates ≥3 times per week showed protective effect on current rhinoconjunctivitis (aOR = 0.45, 95% CI = 0.25-0.79 and aOR = 0.50, 95% CI = 0.29-0.86). Eating lollipops, candies and animal fats ≥3 times per week was positively associated with current rhinoconjunctivitis (aOR = 1.47, 95% CI = 1.00-2.17 and aOR = 2.25, 95% CI = 1.11-4.56). Protective effect of the Mediterranean diet was not significant. CONCLUSIONS Frequent consumption of cereals, rice, pasta and chocolates may have beneficial effect on symptoms of rhinoconjunctivitis. Although dietary habits may affect the prevalence of symptoms of current rhinoconjunctivitis, the Mediterranean diet alone may not be protective against rhinoconjunctivitis.

BACKGROUND Acute asthma is one of the most common medical emergencies in children. Appropriate assessment/treatment and early identification of factors that predict hospitalization are critical for the effective utilization of emergency services. OBJECTIVE To identify risk factors that predict hospitalization and to compare the concordance of the Modified Pulmonary Index Score (MPIS) with the Global Initiative for Asthma (GINA) guideline criteria in terms of attack severity. METHODS The study population was composed of children aged 5-18 years who presented to the Emergency Departments (ED) of the tertiary reference centers of the country within a period of 3 months. Patients were evaluated at the initial presentation and the 1(st) and 4(th) hours. RESULTS Of the 304 patients (median age: 8.0 years [interquartile range: 6.5-9.7]), 51.3% and 19.4% required oral corticosteroids (OCS) and hospitalization, respectively. Attack severity and MPIS were found as predicting factors for hospitalization, but none of the demographic characteristics collected predicted OCS use or hospitalization. Hospitalization status at the 1(st) hour with moderate/severe attack severity showed a sensitivity of 44.1%, specificity of 82.9%, positive predictive value of 38.2%, and negative predictive value of 86.0%; for MPIS ≥ 5, these values were 42.4%, 85.3%, 41.0%, and 86.0%, respectively. Concordance in prediction of hospitalization between the MPIS and the GINA guideline was found to be moderate at the 1(st) hour (κ = 0.577). CONCLUSION Attack severity is a predictive factor for hospitalization in children with acute asthma. Determining attack severity with MPIS and a cut-off value ≥ 5 at the 1(st) hour may help physicians in EDs. Having fewer variables and the ability to calculate a numeric value with MPIS makes it an easy and useful tool in clinical practice.

BACKGROUND This study was performed to evaluate the time trends in prevalence of asthma and related factors in Denizli, Turkey. METHODS Two cross-sectional surveys were performed, 6 years apart (2002 and 2008) using the ISAAC protocol, in the 13-14 age groups and comparisons were made between the results. RESULTS Lifetime prevalence of wheeze, 12 month prevalence of wheeze, and the prevalence of wheeze after exercise in the previous 12 months were significantly increased respectively from 10.2% to 13.4% (POR = 1.37, 95%CI = 1.18-1.58, p < 0.001), from 5.0% to 6.2% (POR = 1.26, 95%CI = 1.02-1.55, p = 0.016) and from 9% to 10.2% (POR = 1.15, 95%CI = 0.98-1.35, p = 0.046) in 2008 study. Doctor diagnosed asthma prevalence also increased significantly from 2.1% to 12.9 (POR = 6.80, 95%CI = 5.22-8.85, p < 0.001). Prevalence of sleep disturbed by wheeze in the last 12 months; but, never woken with wheezing (POR = 1.62, 95%CI = 1.26-2.09, p = < 0.001) and less than one night per week (POR = 1.58, 95%CI = 1.06-2.36, p = 0.013) were significantly increased in 2008 study. Severe attacks of wheeze limiting speech in the last year was increased from 1.3% to 2.2% (POR = 1.67, 95%CI = 1.14-2.43, p = 0.004). The number of wheeze attacks in the previous 12 months was increased significantly for 4-to-12 attacks (POR = 1.54, 95%CI = 1.03-2.32, p = 0.02) in 2008 study. However, prevalence of waking with cough in the last 12 months did not change. While history of family atopy and domestic animal at home were found as significant risk factors for asthma in 2002 study, male gender, history of family atopy and stuffed toys were found significant in 2008. CONCLUSIONS The prevalence of asthma symptoms were increased in Denizli. History of family atopy, male gender and stuffed toys were important risk factors for asthma in 2008.

Background:Childhood atopic dermatitis (AD) is classically accepted as initial finding of atopic march; however, nonatopic cases do not follow this course. The aim of this study was to determine the characteristics and prognosis of AD in childhood in Turkey. Methods:The study included 531 children with AD that presented to pediatric allergy departments in 11 different regions of Turkey. Age at diagnosis, total serum and inhalant-specific immunoglobulin E (IgE) levels and allergen skin prick test results were recorded retrospectively. Clinical characteristics like additional allergic diseases at presentation or during follow-up were recorded as well as duration of follow-up. Results:Mean age at diagnosis was 37.8 ± 36.2 months. Mean IgE level was 318.3 ± 677.8 IU/ml (median 100 IU/ml). Skin prick tests yielded positive results in 47% of children. At presentation, 31.6% of children reported additional allergic disease, while 11.7% developed allergic disease during follow-up. Among all, 46.6% had additional allergic disease at any point. IgE levels were significantly higher in children with additional allergic diseases (p = 0.001). Allergen skin prick test positivity and family history of allergic diseases increased the risk of additional allergic diseases significantly (OR = 3.90, 95% CI = 2.3–6.6 and OR = 1.89, 95% CI = 1.3–2.8, respectively). Conclusions: Allergic sensitization is not present in all cases of AD. Coexistence of additional allergic diseases is not as high as expected but more common in children who have been demonstrated to have atopic sensitization with high IgE levels and allergen skin prick test positivity.
