Respiration; international review of thoracic diseases

Dyspnea is prevalent and has a broad differential diagnosis. Difficulty in determining the correct etiology can delay proper treatment. Non-invasively obtained acoustic signals may offer benefit in identifying patients with dyspnea due to obstructive airway disease (OAD). ⋯ This modality was useful in identifying patients whose dyspnea was due to OAD. The ability to objectively and non-invasively measure these differences may prove clinically useful in distinguishing the operant physiology in patients presenting with acute dyspnea.

Primary Sjögren's syndrome (PSS) is associated with various histological patterns of interstitial lung disease. Although chest images and lung function studies showed that lung involvement predominantly occurs in small airways, pathological findings were not consistent with the results of high-resolution CT (HRCT) and lung function tests. ⋯ The histopathologic patterns of PSS-ILD included lung interstitial involvement and small airway involvement or both. Corticosteroid therapy combined with cyclophosphamide was administered with a favorable response in the majority of patients.

There is more than one mechanism which contributes to the increases in upper airway resistance in obstructive sleep apnea and hypopnea syndrome. Impulse oscillation provides a convenient way of noninvasive monitoring and differentiating the contributions of airway resistance. ⋯ The magnitude of change in airway resistance due to posture is bigger in OSAHS than in non-OSAHS. Zrs, R5 and R20 in supine position were associated moderately with apnea/hypopnea index.

A significant part of the budget of our bronchoscopy unit represents repair costs for damaged bronchoscopes. ⋯ Only a small number of occurrences of bronchoscope damage in our unit are potentially preventable, but they still represent an important expense. The relatively low occurrence of preventable damage is a result of the successful bronchoscopy training program.

Acute respiratory distress syndrome (ARDS) is a common diagnosis in intensive care units (ICUs) and is frequently correlated with acute kidney injury (AKI). ⋯ In patients with ARDS undergoing OLB, the use of the RIFLE score improves prediction of outcome.
