ABSTRACT

OBJETIVO: Estudar a prevalência dos padrões de sibilância respiratória e suas associações com variáveis independentes. MÉTODOS: Coorte de nascidos vivos, 1993, Pelotas (RS); subamostra sistemática de 20 por cento da coorte original acompanhada aos 6 e 12 meses e 4 anos; aos 10-12 anos localizou-se 87,5 por cento da coorte original. Definição dos padrões: transitório: chiado até 4 anos e ausência de chiado aos 10-12 anos; persistente: chiado em todos acompanhamentos; início tardio: chiado aos 10-12 anos. Variáveis independentes: gênero; cor da pele; renda familiar; fumo/asma na gravidez; amamentação; infecção respiratória/diarréia (1º ano); alergia e asma na família (4 e 10-12 anos); diagnóstico médico de rinite/eczema (10-12 anos). RESULTADOS: O total da subamostra foi de 897 adolescentes. Prevalência (IC95 por cento) dos padrões de sibilância: transitório 43,9 por cento (40,7-47,2);persistente 6,4 por cento (4,8-8,0); de início tardio 3,3 por cento (2,2-4,5). O transitório foi mais freqüente em crianças de famílias de baixa renda, com menor duração da amamentação, relato de infecções respiratórias (1º ano) e história familiar de asma (4 anos); o persistente foi quase duas vezes mais freqüente em meninos, em filhos de mulheres com asma na gravidez, com infecções respiratórias (1º ano) e história familiar de asma (4 e 10-12 anos); de início tardio mostrou maior prevalência naqueles com asma na família (10-12 anos) e diagnóstico médico de rinite (10-12 anos); menor prevalência em quem relatou infecções respiratórias (1º ano) e diagnóstico médico de eczema (10-12 anos). CONCLUSÕES: O conhecimento das associações dos padrões sibilantes permite a adoção de medidas preventivas e terapêuticas.


OBJECTIVE: To study the prevalence of wheezing patterns and their associations with independent variables. METHODS: Cohort study of live births in 1993 in Pelotas, Brazil. A systematic subsample (20 percent) of the original cohort was evaluated at 6 months, 12 months and 4 years. At 10-12 years, 87.5 percent of the original cohort was contacted. Wheezing was categorized: transient, wheezing at 4 years but not at 10-12; persistent, wheezing at all evaluations; late-onset, wheezing at 10-12 years. Independent variables were analyzed: gender; skin color; family income; smoking/asthma during pregnancy; breastfeeding; respiratory infection/diarrhea (during the 1st year); family members with asthma/allergy (at 4 years and at 10-12); physician-diagnosed rhinitis/eczema (at 10-12 years). RESULTS: The subsample comprised 897 adolescents. Wheezing patterns were expressed as prevalence (95 percent CI): transient, 43.9 percent (40.7-47.2); persistent, 6.4 percent (4.8-8.0); and late-onset, 3.3 percent (2.2-4.5). The transient pattern was more common in children from low-income families, children breastfed for less time, children with a history of respiratory infections (during the 1st year) and children with asthma in the family (at 4 years). The persistent pattern was almost twice as common in males, in children whose mothers had asthma during pregnancy, in children with respiratory infections (during the 1st year) and in children with asthma in the family (at 4 and 10-12 years). The late-onset pattern was more prevalent among those with asthma in the family (at 10-12 years) and those diagnosed with rhinitis (at 10-12 years), being less prevalent among those reporting respiratory infections (during the 1st year) and those diagnosed with eczema (at 10-12 years). CONCLUSIONS: Knowledge of the associations of wheezing patterns allows us to adopt preventive and therapeutic measures.

ABSTRACT

Eczematous external otitis, because of its basic allergic nature, tends to be chronic or recurrent. The purpose of our study was to investigate the association between allergic contact dermatitis and chronic eczematous external otitis. Sixty-six patients with eczematous external otitis and 48 healthy volunteers were included in this study. All the patients were tested with an epicutaneous patch test. In the study group, the average recurrent attack rate was 6.1+/-1.5 (between 4-9 times during the last year) in the patch test positive eczematous external otitis patients, and 4.9+/-1.3 (between 4-8 times during the last year) in the patch test negative patients (p = 0.002). The epicutaneous patch test was positive in 19 (28.8%) out of 66 cases with chronic eczematous external otitis, and in 3 (6.3%) out of 48 cases in the control group. The difference between the two groups was statistically significant (p = 0.003). The most common reactions were due to neomycin sulfate and potassium dichromate in this study. These results suggest that, in some cases eczematous external otitis may be considered as a form of delayed type hypersensitivity to allergen stimuli. Patients suffering from eczematous external otitis symptoms should be investigated for allergens.

ABSTRACT

The study of food allergy in Singaporean children is still in its infancy. Confusion and misunderstanding is common among the public. Even so, we have found certain unique features regarding food allergy among Singaporean children. "Bird's nest" has been shown to be the most common cause of anaphylaxis requiring medical attention. This allergen has not been described before. Peanuts and tree nuts are extremely uncommon causes of anaphylaxis, unlike the West. However, the pattern of sensitization to foods in children as shown by skin prick test is similar to other Western populations. The reasons for the difference between the profile foods responsible for anaphylactic reactions in our population and those of the western population, despite the similarity in sensitization profiles, are still unclear.

ABSTRACT

Síndrome da pele excitada (SPE) corresponde a uma reaçäo adversa aos testes de contato, caracterizada pela presença de vários testes epicutâneos positivos, muitos näo se reproduzindoem posterior retestagem. Este trabalho dedica-se à revisäo da literatura pertinente, abordando os seguintes tópicos: nomenclatura, índice de perda de testes positivos nos vários trabalhos publicados, fatores predisponentes, estudos experimentais e possíveis mecanismos envolvidos na formaçäo de SPE

ABSTRACT

Se presenta una lactante de 16 años de edad con un eczema perinévico o halo eczema que se desarrolló alrededor de un nevo melanocítico congénito. La dermatosis inflamatoria se inició dos meses antes. El nevo era máculo-papuloso, negro, de 5mm, y con límites mal definidos e irregulares, correspondiendo a una proliferación melanocítica juntural intraepidérmica. La histopatología del area del eczema mostró una dermatitis espongiótica con escasos queratinocitos necrobiótico. Sugerimos que estas imágenes puedan corresponder a dos mecanismos fisiopatológicos inmunes de hipersensibilidad retardada y de citotoxicidad mediados por linfocitos T, desencadenados por la liberación de neoantígenos del nevo. El eczema mejoró espontáneamente en el término de tres meses. El nevo melanocítico permaneció con iguales características

ABSTRACT

Se presenta el caso de un paciente de 25 años de edad con E.A.C. de varios años de evolución. Debido a la cronicidad del proceso se solicita un estudio oftalmológico en el cual se comprueba la presencia de cataratas bilaterales. El interés de esta publicación reside en la importancia de esta conjunción de enfermedades y la prioridad del estudio oftalmológico con lámpara de hendidura en todo paciente con E.A.C. y más aún entre los 20 y 30 años de edad en que con mayor frecuencia se observva esta asociación
