RESUMO
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.

Objetivo: Apresentar um caso raro de toxoplasmose congênita de uma mãe imunocompetente com infecção crônica que teve reativação da doença ocular durante a gestação. Descrição: O recém-nascido estava assintomático no nascimento e foi identificado através de triagem neonatal (IgM anti-Toxoplasma gondii em sangue seco) entre outros 190 bebês com toxoplasmose congênita durante um período de 7 meses. Sua mãe tinha tido um episódio não tratado de reativação de retinocoroidite toxoplásmica durante a gestação, com títulos de IgG estáveis e resultados negativos para IgM. Os resultados de IgM e IgG no soro do recém-nascido e o teste de immunoblotting para IgG foram positivos, e detectou-se lesões retinocoroideanas ativas na periferia da retina. O recém-nascido foi tratado com sulfadiazina, pirimetamina e ácido folínico. Aos 14 meses de vida, a criança permanecia assintomática, com regressão das lesões retinocoroideanas e persistência de IgG. Comentários: É possível que a triagem neonatal sistemática em áreas com alta prevalência de infecção possa identificar esses casos.
Objectives: To report a rare case of congenital toxoplasmosis from an immunocompetent mother with chronic infection who had reactivation of ocular disease during pregnancy. Descriptions:The newborn was asymptomatic at birth and identified by neonatal screening (IgM anti-Toxoplasma gondii in dried blood) among other 190 infants with congenital toxoplasmosis during a 7-month period. His mother had had a non-treated episode of reactivation of toxoplasmic retinochoroiditis during pregnancy, with stable IgG titers and negative IgM results. Results of IgM and IgG in the newborns serum, as well as IgG immunoblotting were positive and active retinochoroidal lesions were detected in his peripheral retina. The neonate was treated with sulfadiazine, pyrimethamine and folinic acid. At 14 months of life, the child remained asymptomatic, with regression of retinochoroidal lesions and persistence of IgG. Comments: It is possible that systematic neonatal screening in areas with high prevalence of infection may identify these cases.
