The impact of anxiety and depression on quality of life (QOL) in adult patients with cystic fibrosis (CF) is fully unknown. We investigated the prevalence and factors associated with anxiety and depression, including QOL, in adult CF patients. ⋯ Anxiety and depressive symptoms are common in adult CF patients. They are associated with poorer QOL, low lung function, reduced physical functioning, and severity of chest symptoms. Therefore, routine screening for symptoms of anxiety and depression is a worthy endeavor, and those identified with elevated clinical symptoms should be referred to receive appropriate treatment.

Air-fluid levels within emphysematous lung bullae are a relatively uncommon occurrence in patients with preexisting bullous disease, and are not commonly reported. We report 2 cases of new onset air-fluid levels in patients with underlying bullous disease with substantially different clinical presentations but with clinical improvement after medical therapy only.

Case Reports
Eosinophilic pneumonia associated with azacitidine in a patient with myelodysplastic syndrome.
Eosinophilic pneumonia is characterized by cough, lung infiltrates on imaging, and by the presence of eosinophils in the alveoli and pulmonary interstitium. Azacitidine, a pyramidine nucleoside analog of cytidine, is FDA approved for the treatment of various myelodysplastic syndromes. ⋯ Diagnosis of drug-induced eosinophilic pneumonia is established by having a temporal relationship between onset of symptoms and initiation of therapy, bronchoalveolar lavage or lung biopsy evidence of pulmonary eosinophilia, no other explanation for the disease, and improvement upon cessation of the offending agent. Our case illustrates the need for a high index of suspicion to identify adverse pulmonary reactions associated with newly developed medications.

Choke points and airway wall structure in expiratory central airway collapse are poorly defined. Computed tomography, white light bronchoscopy, endobronchial ultrasound, vibration response imaging, spirometry, impulse oscillometry, negative expiratory pressure, and intraluminal catheter airway pressure measurements were used in a patient with cough, dyspnea, and recurrent pulmonary infections. Computed tomography and white light bronchoscopy identified dynamic collapse of the trachea and mainstem bronchi, consistent with severe crescent tracheobronchomalacia. ⋯ After Y-stent insertion, the choke point migrated distally. Imaging studies revealed improved airway dynamics, airway patency, and ventilatory function. Novel imaging and physiologic assessments could be used to localize choke points and airway wall structure in tracheobronchomalacia.

Mechanical ventilation technology has evolved rapidly over the last 30 years. One consequence is the creation of an unmanageable number of names to describe modes of ventilation. The proliferation of names makes education of end users difficult, potentially compromising the quality of patient care. ⋯ Survey results indicate that respondents were either familiar with or amenable to the previously published literature that the survey constructs represented. The degree of familiarity and concordance with these constructs represents a sufficient basis for attempting to formalize a taxonomy. Further analysis of the pattern of concordance among the constructs will inform future educational and consensus building efforts.
