Randomized Controlled TrialConcomitant treatment with nebulized formoterol and tiotropium in subjects with COPD: a placebo-controlled trial.
Adding a long-acting beta(2)-agonist (LABA) by dry powder inhaler (DPI) to tiotropium provides significantly increased and sustained bronchodilation in chronic obstructive pulmonary disease (COPD) patients over either product alone. To demonstrate similar benefits with a nebulized LABA, a placebo-controlled trial was conducted to evaluate the efficacy and safety of formoterol fumarate inhalation solution in subjects receiving tiotropium as a maintenance treatment for COPD. After a 7-14-day screening period using tiotropium 18 microg once daily, subjects with diagnosed COPD (> or = 25% to <65% predicted FEV(1)) were randomized to receive 20 microg formoterol fumarate inhalation solution twice daily for nebulization plus tiotropium (FFIS/TIO) or nebulized placebo twice daily plus tiotropium (PLA/TIO) for 6 weeks. ⋯ PLA/TIO (p=0.04). More PLA/TIO- than FFIS/TIO-treated subjects experienced AEs (39.7% vs. 22.9%), COPD exacerbations (7.9% vs. 4.5%), and serious AEs (3.2% vs. 1.5%). Nebulized formoterol fumarate in combination with tiotropium provided statistically and clinically significant improvements in bronchodilation and symptom control over tiotropium alone and demonstrated good tolerability.

An innovative maintenance follow-up program after a first inpatient pulmonary rehabilitation.
Although the benefits of pulmonary rehabilitation (PR) have been demonstrated in patients with COPD, most studies suggest that short-term programs are insufficient to maintain the benefits beyond a post-discharge period of 6 months to 1 year. We were interested to evaluate the effects of an innovative maintenance intervention compared with a usual after-care. Forty moderate to severe COPD patients, who had just completed their first inpatient PR, were consecutively included in either a maintenance group (MG) or a standard after-care group. ⋯ The results showed no difference between groups in dyspnea and maximal workload. We also found that the number of days spent in hospital for respiratory disorders was significantly lower in the MG after 12 months (p < or = 0.03). The multidisciplinary management of COPD patients in the post-rehabilitation period within a health-care network including self-help associations seems to be an effective strategy for maintaining, and even improving, the benefits of a first initial structured program.

Inspiratory capacity predicts mortality in patients with chronic obstructive pulmonary disease.
Chronic obstructive pulmonary disease (COPD) severity is usually graded upon the FEV(1) reduction and FEV(1) has been considered the most important mortality predictor with age in COPD. Recent studies suggest other factors as more powerfully related to mortality than FEV(1) in COPD patients. ⋯ IC (%pred.) is a powerful functional predictor of all-cause and respiratory mortality and of exacerbation-related hospital admissions in COPD patients.

Comparative StudyNasal nitric oxide for early diagnosis of primary ciliary dyskinesia: practical issues in children.
Primary ciliary dyskinesia (PCD) is a genetic disease characterized by abnormally beating cilia. In these patients, levels of nasal nitric oxide (nNO) are lower than those observed in healthy subjects. ⋯ Healthy children have higher nNO levels than PCD patients. In 15% of uncooperative healthy children can be found low nNO levels, similar to PCD patients, but those values increased some months later, in successive evaluations. Nasal NO may be used for PCD screening even though repeated evaluations may be necessary in young children.

Coccidioidomycosis is a common fungal infection primarily affecting the lungs. The prevalence and the characteristics of pleural effusion in Coccidioidomycosis are not well described. Therefore, a retrospective analysis of data from patients admitted to a teaching hospital with a diagnosis of Coccidioidomycosis and pleural effusion was done. ⋯ Pleural effusions are common in hospitalized patients with Coccidioidomycosis. Pleural fluid eosinophilia should alert clinician to Coccidioides immitis as a possible etiological agent especially in an endemic area. Empyema occurred in a quarter of pleural effusions and resolution required thoracotomy.
