Development Process and Cognitive Testing of CARATkids - Control of Allergic Rhinitis and Asthma Test for Children

Background: Allergic rhinitis and asthma (ARA) are chronic inflammatory diseases of the airways that often coexist in children. The only tool to assess the ARA control, the Control of Allergic Rhinitis and Asthma Test (CARAT) is to be used by adults. We aimed to develop the Pediatric version of Control of Allergic Rhinitis and Asthma Test (CARATkids) and to test its comprehensibility in children with 4 to 12 years of age. Methods: The questionnaire development included a literature review of pediatric questionnaires on asthma and/or rhinitis control and two consensus meetings of a multidisciplinary group. Cognitive testing was carried out in a cross-sectional qualitative study using cognitive interviews. Results: Four questionnaires to assess asthma and none to assess rhinitis control in children were identified. The multidisciplinary group produced a questionnaire version for children with 17 questions with illustrations and dichotomous (yes/no) response format. The version for caregivers had 4-points and dichotomous scales. Twenty-nine children, 4 to 12 years old, and their caregivers were interviewed. Only children over 6 years old could adequately answer the questionnaire. A few words/expressions were not fully understood by children of 6 to 8 years old. The drawings illustrating the questions were considered helpful by children and caregivers. Caregivers considered the questionnaire complete and clear and preferred dichotomous over the 4-points scales. The proportion of agreement between children and their caregivers was 61%. The words/expressions that were difficult to understand were amended. Conclusion: CARATkids, the first questionnaire to assess a child’s asthma and rhinitis control was developed and its content validity was assured. Cognitive testing showed that CARATKids is well-understood by children 6 to 12 years old. The questionnaire’s measurement properties can now be assessed in a validation study.

Uveíte, Sífilis e SIDA

Os autores apresentam o caso clínico de um homem de 55 anos com antecedentes de sífilis primária na juventude e quatro reinfecções posteriores, a última das quais há dois anos, adequadamente tratada e com remissão do quadro. Observado em consulta externa de Oftalmologia, por olho vermelho, foi-lhe diagnosticada pan-uveíte, com íris de características sifilíticas (roséola sifilítica). Na sua avaliação laboratorial salientaram-se: Venereal Disease Research Laboratory (VDRL) positivo, Fluorescent Treponemal Antibody Absorbed Test (FTA-ABS) positivo, Vírus da Imunodeficiência Humana (VIH-1) positivo. Internado no Serviço de Medicina, foi submetido a punção lombar, tendo a análise do liquor revelado pleocitose, proteinorraquia aumentada, VDRL negativo, Treponema Pallidum Hemagglutination Assay (TPHA) positivo e FTA/ABS positivo, aspectos estes compatíveis com envolvimento sifilítico do SNC. O diagnóstico de neurosífilis assintomática nos doentes duplamente infectados é difícil e complexo, pois fundamenta-se em testes serológicos que não obedecem ao padrão habitual. A terapêutica é controversa, devido à recorrência dos quadros neurológicos após terapêuticas consideradas adequadas, sendo recomendada vigilância apertada destes doentes.
