ABSTRACT

AIMS: To evaluate a telemonitoring strategy based on automated text messaging and telephone support after heart failure (HF) hospitalization. METHODS AND RESULTS: The MESSAGE-HF study is a prospective multicentre, randomized, nationwide trial enrolling patients from 30 clinics in all regions of Brazil. HF patients with reduced left ventricular ejection fraction (<40%) and access to mobile phones are eligible after an acute decompensated HF hospitalization. Patients meeting eligibility criteria undergo an initial feasibility text messaging assessment and are randomized to usual care or telemonitoring intervention. All patients receive a HF booklet with basic information and recommendations about self-care. Patients in the intervention group receive four daily short text messages (educational and feedback) during the first 30 days of the protocol to optimize self-care; the feedback text messages from patients could trigger diuretic adjustments or a telephone call from the healthcare team. After 30 days, the frequency of text messages can be adjusted. Patients are followed up after 30, 90, and 180 days, with final status ascertained at 365 days by telephone. Our primary endpoint is the change in N-terminal pro-brain natriuretic peptide (NT-proBNP) levels after 180 days. Secondary endpoints include changes in NT-proBNP after 30 days; health-related quality of life, HF self-care, and knowledge scales after 30 and 180 days; and a composite outcome of HF hospitalization and cardiovascular death, adjudicated by a blinded and independent committee. CONCLUSIONS: The MESSAGE-HF trial is evaluating an educational and self-care promotion strategy involving a simple, intensive, and tailored telemonitoring system. If proven effective, it could be applied to a broader population worldwide.

ABSTRACT

Lipoid pneumonia (LP) is a pneumonitis resulting from the aspiration of lipids, and is commonly associated with the use of mineral oil as a laxative. LP is relatively unfamiliar to clinicians and is probably underdiagnosed. Making a diagnosis of LP requires a high degree of clinical suspicion. The aim of this publication are to present a case of a patient with LP and to increase physician awareness of LP, its diagnosis and prevention.

ABSTRACT

OBJECTIVE: To present the high-resolution computed tomography (HRCT) findings of pulmonary alveolar microlithiasis. METHODS: The HRCT scans of 10 adult patients (seven females and three males; mean age, 38.7 years) were retrospectively analyzed. The films were studied independently by two radiologists. RESULTS: The most common tomographic findings were ground-glass attenuation and linear subpleural calcifications, which were seen in 90% of the patients. Other relevant findings were small parenchymal nodules, calcification along the interlobular septa, nodular cissures, subpleural nodules, subpleural cysts, dense consolidations, and a mosaic pattern of attenuation. CONCLUSIONS: The HRCT findings presented by individuals with pulmonary alveolar microlithiasis are distinct. In most cases, such findings can form the basis of the diagnosis, eliminating the need to perform a lung biopsy.

ABSTRACT

OBJETIVO: Apresentar os achados na tomografia computadorizada de alta resolução (TCAR) do tórax da microlitíase alveolar pulmonar. MÉTODOS: Foram estudadas, retrospectivamente, as tomografias de dez pacientes adultos, sete mulheres e três homens, com idade média de 38,7 anos. Os exames foram analisados por dois radiologistas, de forma independente, e as decisões finais foram obtidas por consenso. RESULTADOS: Os achados mais freqüentes foram as opacidades em vidro fosco e as calcificações subpleurais, ambas presentes em 90 por cento dos pacientes estudados. Os outros achados de maior relevância foram pequenos nódulos parenquimatosos, calcificação ao longo dos septos interlobulares, cissuras nodulares, nódulos subpleurais, cistos subpleurais, consolidações densas e padrão de pavimentação em mosaico. CONCLUSÕES: A microlitíase alveolar pulmonar apresenta aspectos na TCAR que são altamente sugestivos da doença, na maior parte dos casos dispensando a realização de biópsias pulmonares.

ABSTRACT

Introdução: a determinação dos volumes pulmonares é desejada como complemento da espirografia; contudo, o alto custo do equipamento faz com que seu uso seja restrito e que novas técnicas sejam investigadas. Metodologia: foram analisados 20 asmáticos, em acompanhamento no HU Gaffrée Guinle, classificados, segundo Consenso Brasileiro (2002), em asma moderada (n=9) e grave (n=11). Foram obtidos os valores da capacidade pulmonar total e volume residual pelas técnicas pletismográficas, CPTPL e VRPL, e radiológicas, CPTRA e VRRA, além dos parâmetros da espirografia. Resultados: a amostra foi constituída por 13 mulheres e 7 homens, sendo a média de idade de 47,6 anos. A intensidade da disfunção, medida pela relação VEF1/CVF foi de 58,8% (IC95% entre 53,9% e 63,6%). Os valores, expressos em litros e pela média, da CPTPL (5,94) e VRPL (2,55) foram significativamente diferentes daqueles valores de CPTRA (4,60) e VRRA (2,94). A prova broncodilatadora não produziu alteração na CPT, em nenhuma das técnicas; contudo, alterou significativamente o VR, em ambas. Foram determinadas equações de regressão para previsão dos valores de CPTPL e VRPL, a partir de parâmetros espirográficos e radiológicos. A melhor regressão linear univariada, com r2=0,88, é: CPTPL= (CPTRA*1,072)+0,9981, sendo o erro padrão de 0,48. A regressão para VR, com r2=0,76, é: VRPL=(VRRA*1,02)-0,4451. Conclusão: a técnica radiológica não dá resultados iguais aos da pletismográfica, para CPT e VR, tanto antes como após a broncodilatação.

ABSTRACT

Os autores descrevem um caso de pneumonia por Legionella pneumophilia que evoluiu com insuficiência respiratória aguda grave e óbito. A legionelose foi reconhecida como uma entidade nosológica em 1976, durante um surto epidêmico nos EUA. As facilidades diagnósticas vêm modificando o antigo conceito de que se tratava de doença incomum. A constataçäo de que esta pneumonia - de morbidade e mortalidade elevadas - É freqüente obriga a um redimensionamento de sua importância, na prática médica diária.
