Abstract
AIM To evaluate the effects of rapid maxillary expansion (RME) on nasal patency in mouth breathing (MB) children with maxillary atresia due to or not due to allergic rhinitis (AR) associated with asthma. METHODS Fifty-three MB children/adolescents (aged 7-14 years) with mixed or permanent dentition and maxillary atresia participated, with or without unilateral or bilateral crossbite. They formed the groups: RAD (AR + asthma; clinical treatment, RME); RAC (AR + asthma; clinical treatment, no RME); and D (mouth breathers; RME only). RAD and RAC patients received topical nasal corticosteroid and/or systemic H1 antihistamine (continuous use) and environmental exposure control. All were evaluated before RME (T1) and 6 months after (T2) with the CARATkids score, acoustic rhinometry, and nasal cavity computed tomography (CT). Patients RAD and D underwent RME (Hyrax® orthopedic appliance). RESULTS A significant reduction in the CARATkids score occurred in the RAD (-4.06; p < 0.05), similarly when patient and parent/guardian scores were evaluated (-3.28 and -3.16, respectively). Acoustic rhinometry (V5) showed increased nasal volume in all groups, significantly higher in RAD patients than in RAC and D (0.99 × 0.71 × 0.69 cm3, respectively). CT of the nasal cavity documented increased volume in all three groups, with no significant differences between them. CONCLUSION In MB patients with AR, asthma, and maxillary atresia, RME increased nasal cavity volume and improved respiratory symptoms. However, it should not be used as the only treatment for managing patients with respiratory allergies.

Abstract
We investigated the prevalence of asthma and factors related to asthma development in schoolchildren aged 6 to 14, living in central and peripheral areas of the city of Montes Claros, Minas Gerais and who were registered with the Family Health Strategy program. Initially, a standard written questionnaire, based on ISAAC (International Study of Asthma and Allergies in Childhood), was administered to collect personal data, information regarding income, asthma prevalence, allergic rhinitis and eczema (N = 1,131). Secondly, a case-control study was performed by grouping the patients as either asthmatic (A; N = 172) or non-asthmatic (NA; N = 379). Potential factors associated with the occurrence of asthma were evaluated using the complementary questionnaire from ISAAC phase II. Skin tests for immediate hypersensitivity (STIH) and parasitological tests were also performed. The odds ratio, estimated by multivariate analysis, indicated that asthma cases were related to kindergarten attendance, household smoking, family history of asthma, rhinitis and positive STIH. It was concluded that, in the studied population, the prevalence of asthma was related to genetic predisposition, in addition to individual history, social demographics, exposure to pollutants such as tobacco smoke and a positive response to allergy testing.

Abstract
BACKGROUND The Control of Allergic Rhinitis and Asthma Test for Children (CARATKids) assesses asthma and allergic rhinitis control in children younger than 12 years. OBJECTIVE To validate the Brazilian Portuguese version of the CARATKids and to define the cutoff values for identifying uncontrolled disease. METHODS Children aged 6 to 12 years with asthma and allergic rhinitis were studied (n = 102). CARATKids, childhood Asthma Control Test (cACT), total nasal symptom score (TNSS), and visual analog scale (VAS) scores were obtained at baseline and after 4 to 6 weeks. Internal consistency, test-retest reliability, responsiveness, and validity of the Brazilian CARATKids were assessed according to the Consensus-based Standards for the Selection of Health Measurements Instruments checklist. The minimal clinically important difference (MCID) was evaluated using distribution and anchor methods. Spearman correlations were used to compare CARATKids scores with external measures of control. Receiver operating characteristic curve analysis was performed to establish cutoff values. RESULTS Fifty children completed both visits. The Cronbach α and intraclass correlation coefficient of CARATKids were 0.81 and 0.85, respectively. The Guyatt responsiveness index was -1.34, and within-patient change in clinically unstable patients (n = 31) was significant (P = .02). As for cross-sectional and longitudinal validity, correlation coefficients ranged from 0.58 to 0.77 (P < .001) and 0.30 to 0.57 (P < .05), respectively. The estimated MCID for CARATKids was 3. The optimal cutoffs (sensitivity and specificity) to exclude uncontrolled and controlled disease were 3 or less (97% and 67%) and 6 or greater (56% and 96%), respectively. CONCLUSION CARATKids is a reliable and valid tool to assess asthma and allergic rhinitis control in Brazilian children. A score of 6 or higher on CARATKids identifies uncontrolled disease, and a score of 3 or lower excludes poor disease control.

Abstract
Introduction Allergic rhinitis is a common disease among children and adolescents, reaching up to 40% of the population. During childhood, it is usually underdiagnosed because it has nonspecific symptoms. It has a negative impact on quality of life and may predispose to comorbidities. The diagnosis is clinical and treatment aims prevention. Objective The objective of this study is to evaluate the quality of life in pediatric patients with allergic rhinitis. Methods This is an observational study with cross-sectional design. The population consisted of pediatric patients with allergic rhinitis treated at the Medical Clinic of Integrated Education (MCIE) - Universidade do Sul de Santa Catarina - Unisul, Tubarão, SC, Brazil. We collected data from March to June 2016 through the application of the Sociodemographic and Health Questionnaire, rhinitis module of the International Study of Asthma and Allergies in Childhood Questionnaire and the Rhinoconjunctivitis Quality of Life Questionnaire Modified. Results Out of the 69 respondents, 52.2% were boys with a mean age of 10.13 years old. The predominant education level of parents/guardians was incomplete second grade and average income level was two minimum wages. 81.2% said they had previous treatment for AR, 30.4% had asthma and 7.2% eczema. Incidence of patients smoking was absent and family (parents/guardians) smoking was 17.4%. March to July were the months of highest symptom occurrence, slightly disturbing daily activities. The mean value of severity was 51.9, nasal symptoms were the most uncomfortable, and nasal itchiness was the most cited. Conclusion Our results highlight that allergic symptoms negatively impact the life of people with allergic rhinitis, with a predominance of nasal symptoms, especially nasal itchy, representing a poor quality of life of the interviewed.

Abstract
OBJECTIVE To estimate asthma prevalence, severity, and associated factors in adolescents who live in a low relative humidity environment. METHODS In this cross-sectional study, adolescents aged 13-14 years from the city of Petrolina located in the Brazilian semiarid region answered the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. The possible explanatory variables of the study were gender, family income, mother's education, smokers in the household, parental history of asthma, personal history of allergic rhinitis or atopic dermatitis, and physical activity level. Poisson regression analysis was used to assess the association between asthma and the explanatory variables. RESULTS A total of 1591 adolescents participated in the study, of whom 49.7% were male. The prevalence of active asthma, severe asthma, and physician-diagnosed asthma were 14.0%, 10.4%, and 17.8%, respectively. Adolescents with asthma missed more school days than their peers (33 vs. 22 days/year; p<0.03). Associated factors that remained significant after adjustment were history of asthma in parents (PR=2.65, p<0.001) and personal diagnosis of allergic rhinitis (PR=1.96, p<0.001) and/or atopic dermatitis (PR=2.18, p<0.001). CONCLUSION Asthma prevalence in this low-humidity environment was lower, but more severe than those reported in other Brazilian cities. The dry climate might hamper disease control and this may have contributed to the higher school absenteeism observed. The association of asthma with allergic rhinitis and atopic dermatitis as well as a history of asthma in parents suggests that atopy is an important risk factor for asthma in this population.

Abstract
Background Allergen immunotherapy (AIT) may be prescribed for patients with allergic rhinitis (AR) induced by house dust mites (HDM) whether asthma is present or not. Current guidelines provide insufficient support for therapeutic management strategy of these patients. Allergists however have long-term experience with AIT. This study aims to describe the characteristics of the patients seen in clinical practice with HDM allergy and the process used to determine whether AIT should be initiated. Methods This was an observational, multicenter, prospective and cross-sectional study, conducted in France from 2013 to 2014 with a representative sample of allergy specialists. Any patient over 5 years of age with confirmed HDM allergy untreated with AIT within the last 12 months was eligible. Data were prospectively collected using physician and patient questionnaires. Results A total of 1589 patients (60 % adults, 40 % children) were included by 195 randomly selected allergists. A subgroup of 1212 patients (median age: 22 years; 52 % women) were selected for AIT treatment with a median time of AR diagnosis of 3 years. Amongst these, 59 % had a moderate to severe persistent AR according to AR and its Impact on Asthma guidelines, 57.5 % were polysensitized, and 56.5 % also suffered from conjunctivitis (median rhinitis total symptom score: 11). Asthma was present in 42 % of patients, and was controlled according to Global Initiative for Asthma guidelines in 62 % of patients. The asthma control questionnaire score was 1–1.5 in 20 % and ≥1.5 in 37 % of patients. A total of 57 % patients received a prescription of ≥2 medications (mainly antihistamines). Usual daily activities and sleep quality were slightly-to-moderately impaired as the mean rhinoconjunctivitis quality of life questionnaire score was 2.7 ± 1.5. The major driver of AIT prescription is AR uncontrolled by previous medications leading to patient dissatisfaction. Conclusions HDM-AR associated conjunctivitis was present in 60 % and asthma in 40 % of cases. In >40 % of these cases, asthma was inadequately controlled at the start of AIT.

Abstract
Objective: To assess asthma among Brazilian pediatric population applying the International
Study of Asthma and Allergies in Childhood (ISAAC), an internationally
standardized and validated protocol. Data sources: ISAAC was conceived to maximize the value of epidemiologic studies on asthma and
allergic diseases, establishing a standardized method (self-applicable written
questionnaire and/or video questionnaire) capable to facilitate the international
collaboration. Designed to be carried out in three successive and dependent
phases, the ISAAC gathered a casuistic hitherto unimaginable in the world and in
Brazil. This review included data gathered from ISAAC official Brazilian centers
and others who used this method. Data synthesis: At the end of the first phase, it has been documented that the prevalence of
asthma among Brazilian schoolchildren was the eighth among all centers
participating all over the world. Few centers participated in the second phase and
investigated possible etiological factors, especially those suggested by the first
phase, and brought forth many conjectures. The third phase, repeated seven years
later, assessed the evolutionary trend of asthma and allergic diseases prevalence
in centers that participated simultaneously in phases I and III and in other
centers not involved in phase I. Conclusions: In Brazil, the ISAAC study showed that asthma is a disease of high prevalence and
impact in children and adolescents and should be seen as a Public Health problem.
Important regional variations, not well understood yet, and several risk factors
were found, which makes us wonder: is there only one or many asthmas in Brazil?

Abstract
BACKGROUND The prevalence of asthma in the Brazilian Amazon region is unknown. We studied the prevalence of asthma and associated factors in adolescents (13-14 years old) living in Belem, a large urban centre in this region. METHODS 3725 adolescents were evaluated according to the International Study of Asthma and Allergies in Childhood (ISAAC) protocol and a random sample of them (126 asthmatics and 254 non-asthmatics) were assessed for possible risk factors by a supplementary questionnaire (ISAAC Phase II) and skin prick tests with aeroallergens. The association between asthma and associated factors was determined by logistic regression analysis. RESULTS 3708 adolescents were enrolled, 48% were male. The prevalence of asthma in the last 12 months (identified as asthmatics) and the medical diagnosis of asthma were 20.7% and 29.3%, respectively. Risk factors significantly associated with asthma were: previous diagnosis of tuberculosis (odds ratio [OR]=38.9; 95% confidence interval [95% CI]: 4.6-328.0) and measles (OR=4.7; 95% CI: 2.3-9.8), breastfeeding for any length of time (OR=4.2; 95% CI: 1.1-15.2), current rhinitis (OR=3.2; 95% CI: 1.8-5.9), exposure to smokers (OR=2.4; 95% CI: 1.2-4.5), moisture in home (OR=1.8; 95% CI: 1.1-3.2) and rhinitis diagnosed by physician (OR=1.7; 95% CI: 1.2-2.9). Sensitisation to at least one aeroallergen was significantly higher among asthmatic adolescents (86.5% vs. 32.4%; p<0.0001). CONCLUSIONS The prevalence of asthma was similar to that observed in other Brazilian centres. Physician-diagnosed asthma was more frequent than the presence of symptoms suggestive of asthma. Infectious diseases, nutritional and environmental factors, as well as concomitant allergic rhinitis, were the main risk factors associated with the development of asthma in these adolescents.

Abstract
OBJECTIVE Subjects exposed to laboratory animals are at a heightened risk of developing respiratory and allergic diseases. These diseases can be prevented by simple measures such as the use of personal protective equipment. We report here the primary findings of the Laboratory Animals and Respiratory Allergies Study regarding the prevalence of allergic diseases among laboratory animal workers, the routine use of preventive measures in laboratories and animal facilities, and the need for prevention programs. METHODS Animal handlers and non-animal handlers from 2 Brazilian universities (University of São Paulo and State University of Campinas) answered specific questionnaires to assess work conditions and symptoms. These subjects also underwent spirometry, a bronchial challenge test with mannitol, and skin prick tests for 11 common allergens and 5 occupational allergens (rat, mouse, guinea pig, hamster, and rabbit). RESULTS Four hundred fifty-five animal handlers (32±10 years old [mean±SD], 209 men) and 387 non-animal handlers (33±11 years old, 121 men) were evaluated. Sensitization to occupational allergens was higher among animal handlers (16%) than non-animal handlers (3%, p<0.01). Accessibility to personal protective equipment was measured at 85% (median, considering 73 workplaces of the animal handler group). Nineteen percent of the animal handlers indicated that they wear a respirator at all times while handling animals or working in the animal room, and only 25% of the animal handlers had received an orientation about animal-induced allergies, asthma, or rhinitis. CONCLUSION In conclusion, our data indicate that preventive programs are necessary. We suggest providing individual advice to workers associated with institutional programs to promote a safer work environment.
