RESUMEN
ABSTRACT BACKGROUND: Use of inhaled corticosteroids for managing acute asthma exacerbations has been tested since the 1990s. OBJECTIVE: To compare high doses of inhaled ciclesonide with systemic hydrocortisone for managing acute asthma exacerbations in the emergency department. DESIGN AND SETTING: Double-blind, randomized clinical trial in the public healthcare system of the city of São Paulo. METHODS: Fifty-eight patients with moderate or severe asthma with peak flow < 50% of predicted were randomized into two groups. Over the course of four hours, one group received 1440 mcg of inhaled ciclesonide plus hydrocortisone-identical placebo (ciclesonide + placebo), while the other received 500 mg of intravenous hydrocortisone plus ciclesonide-identical placebo (hydrocortisone + placebo). Both groups received short-acting bronchodilators (fenoterol hydrobromide and ipratropium bromide). The research protocol included spirometry, clinical evaluation, vital signs and electrocardiogram monitoring. Data were obtained at 30 (baseline), 60, 90, 120, 180, and 240 minutes. We compared data from baseline to hour 4, between and within groups. RESULTS: Overall, 31 patients received ciclesonide + placebo and 27 received hydrocortisone + placebo. Inhaled ciclesonide was as effective as intravenous hydrocortisone for improving clinical parameters (Borg-scored dyspnea, P = 0.95; sternocleidomastoid muscle use, P = 0.55; wheezing, P = 0.55; respiratory effort, P = 0.95); and spirometric parameters (forced vital capacity, P = 0.50; forced expiratory volume in the first second, P = 0.83; peak expiratory flow, P = 0.51). CONCLUSIONS: Inhaled ciclesonide was not inferior to systemic hydrocortisone for managing acute asthma exacerbations, and it improved both clinical and spirometric parameters. TRIAL REGISTRATION: RBR-6XWC26 - Registro Brasileiro de Ensaios Clínicos (http://www.ensaiosclinicos.gov.br/rg/RBR-6xwc26/).

O rim ectópico intratorácico é uma anomalia rara. De todas as ectopias renais é a mais rara (p = 0,005 por cento). Relata-se um caso de ectopia renal intratorácica em um homem negro de 83 anos, que procurou atendimento médico com quadro clínico compatível com enfisema pulmonar. Foi solicitado radiograma de tórax, que evidenciou uma massa, diagnosticada por tomografia computadorizada como ectopia renal. A maioria dos casos de rim torácico aparece como uma tumoração intratorácica encontrada em radiogramas de tórax solicitados por qualquer outra razão alheia à suspeita dessa anomalia, e não necessita de tratamento específico.
