The term bronchial hyperresponsiveness is generally used to describe a heightened airway smooth muscle bronchoconstrictor response measured by bronchoprovocation testing. However, the airway also responds to inflammation or bronchoprovocation with increased mucus secretion. We use the term "secretory hyperresponsiveness" to mean increased mucus secretion either intrinsically or in response to bronchoprovocation. ⋯ An extreme form of secretory hyperresponsiveness may lead to plastic bronchitis, a disease characterized by rigid branching mucus casts that obstruct the airway. Secretory hyperresponsiveness and mucus hypersecretion appear to be related to activation of the extracellular-regulated kinase 1/2, signaling through the epidermal growth factor receptor, or secretory phospholipases A2. Recognizing secretory hyperresponsiveness as a distinct clinical entity may lead to more effective and targeted therapy for these diseases.

Lobectomy for non-small cell lung cancer (NSCLC) can be performed either through open thoracotomy or video-assisted thoracoscopic surgery (VATS). To improve the understanding of current attitudes of the thoracic community toward VATS lobectomy, the Collaborative Research Group conducted the Cross-sectional Survey on Lobectomy Approach (X-SOLA) study. We surveyed a large cohort of lobectomy-performing thoracic surgeons to examine their adoption of VATS lobectomy and their opinions of this technique vs conventional open thoracotomy. ⋯ X-SOLA represents the largest cross-sectional report within the thoracic community to date, demonstrating the penetration of VATS lobectomy for NSCLC internationally. From our study, we were able to identify a number of obstacles to broaden the adoption of this minimally invasive technique.

Over 1.5 million pleural effusions occur in the United States every year as a consequence of a variety of inflammatory, infectious, and malignant conditions. Although rarely fatal in isolation, pleural effusions are often a marker of a serious underlying medical condition and contribute to significant patient morbidity, quality-of-life reduction, and mortality. ⋯ The last decade has seen greater implementation of real-time imaging assistance for pleural effusion management and increasing use of smaller bore percutaneous chest tubes. This article will briefly review recent pleural effusion management literature and update the latest changes in common procedural terminology billing codes as reflected in the changing landscape of imaging use and percutaneous approaches to pleural disease management.

A 42-year-old man was directly admitted to the ICU with respiratory failure and hypotension. Two weeks prior and just after returning from Bangladesh, he presented to a polyclinic with fever, right knee pain, and generalized aches, for which he received oral antibiotics. He was a farmer, had diabetes, never smoked, and consumed alcohol occasionally.

A 62-year-old white woman was admitted with shortness of breath, wheezing, and cough. While in the hospital a generalized pruritic skin rash developed on her trunk and upper and lower extremities. She did not have any fevers, chills, or night sweats. ⋯ She had no family history of asthma. The patient was a life-long nonsmoker and did not drink alcohol. During this hospitalization, she was started on prednisone 40 mg/d po in addition to her home medications.
