Randomized Controlled Trial
Factors associated with the minimal clinically important difference for health-related quality of life after physical conditioning in patients with COPD.
To identify factors associated with the minimal clinically important difference (MCID) for health-related quality of life (HRQoL) after physical conditioning in patients with COPD. ⋯ Achieving the MCID for HRQoL after physical conditioning is associated with dyspnea reduction in COPD patients. Therefore, there is a need to develop treatment strategies designed to interrupt the dyspnea-inactivity-dyspnea cycle in such patients.

To present aspects of the evolution of lipoid pneumonia in children, based on clinical, radiological and bronchoalveolar lavage fluid findings, emphasizing the importance of bronchoalveolar lavage for the diagnosis and treatment. ⋯ A diagnosis of lipoid pneumonia should be considered in patients with chronic refractory pneumonia or TB, especially if there is a history of mineral oil ingestion. Bronchoscopy with multiple bronchoalveolar lavages was an efficient treatment for the clearance of mineral oil from the lung parenchyma and the prevention of fibrosis. This strategy contributed to reducing the morbidity of lipoid pneumonia, which remains a rare diagnosis.

Review Case Reports
Post-intubation tracheal injury: report of three cases and literature review.
Post-intubation tracheal injury is a rare and potentially fatal complication. Among the most common causes, cuff overinflation and repetitive attempts of orotracheal intubation in emergency situations are paramount. ⋯ Both conservative and surgical management apply, and the decision-making process depends on the patient profile (comorbidities, respiratory stability), characteristics of the lesion (size and location) and the time elapsed between the occurrence of the injury and the diagnosis. We report the cases of three patients presenting tracheal laceration due to traumatic orotracheal intubation, two submitted to surgical treatment and one submitted to conservative treatment.

Pulmonary eosinophilia comprises a heterogeneous group of diseases defined by eosinophilia in pulmonary infiltrates (bronchoalveolar lavage fluid) or in tissue (lung biopsy specimens). Although the inflammatory infiltrate is composed of macrophages, lymphocytes, neutrophils and eosinophils, eosinophilia is an important marker for the diagnosis and treatment. Clinical and radiological presentations can include simple pulmonary eosinophilia, chronic eosinophilic pneumonia, acute eosinophilic pneumonia, allergic bronchopulmonary aspergillosis and pulmonary eosinophilia associated with a systemic disease, such as in Churg-Strauss syndrome and hypereosinophilic syndrome. ⋯ The radiological presentation can be typical, or at least suggestive, of one of three types of pulmonary eosinophilia: chronic eosinophilic pneumonia, acute eosinophilic pneumonia and allergic bronchopulmonary aspergillosis. The etiology of pulmonary eosinophilia can be either primary (idiopathic) or secondary, due to known causes, such as drugs, parasites, fungal infection, mycobacterial infection, irradiation and toxins. Pulmonary eosinophilia can be also associated with diffuse lung diseases, connective tissue diseases and neoplasia.

To evaluate the diagnostic performance of the rapid shallow breathing index (RSBI) in predicting extubation failure among adult patients in the intensive care unit and to determine the appropriateness of the classical RSBI cut-off value. ⋯ The classical RSBI cut-off value proved inappropriate, predicting only 20% of the cases of extubation failure in our sample. The new cut-off value provided substantial improvement in sensitivity, with an acceptable loss of specificity. The area under the ROC curve indicated that the discriminative power of the RSBI is satisfactory, which justifies the validation of this index for use.
