Deletion of vitamin D receptor leads to premature emphysema/COPD by increased matrix metalloproteinases and lymphoid aggregates formation [PDF]

, 2011
Deficiency of vitamin D is associated with accelerated decline in lung function. Vitamin D is a ligand for nuclear hormone vitamin D receptor (VDR), and upon binding it modulates various cellular functions.

Rare But Risky: Clinical Impacts of Pneumothorax After Thyroidectomy and Parathyroidectomy

The Laryngoscope, Volume 136, Issue 10, Page 4589-4595, October 2026.
Postoperative pneumothorax (PPTX) is rare after thyroidectomy or parathyroidectomy, occurring in up to 0.10% of cases. However, it is associated with increased risks of all‐cause mortality, adverse respiratory events, and healthcare utilization rates in up to 1 year after surgery, deeming PPTX as a potential marker of increased postoperative ...

Hamman's crunch—A pathognomonic sign of pneumomediastinum

Equine Veterinary Education, Volume 38, Issue 9, Page e571-e576, September 2026.
Summary Pneumomediastinum, particularly spontaneous pneumomediastinum, is uncommon and presents a diagnostic challenge. In human medicine, auscultation of Hamman's crunch, a crepitant, crunching noise, audible over the cardiac region in synchrony with the heartbeat, is considered pathognomonic for pneumomediastinum.

Local lung responses following endobronchial elastase and lipopolysaccharide instillation in sheep [PDF]

, 2006
Chronic lipopolysaccharide (LPS) exposure may contribute to the pathogenesis of a number of lung diseases including COPD and emphysema. We sought to develop a large-animal model of emphysema using repeated LPS administration into sheep lung segments.

Early stage nonsmall cell lung cancer: Toward a risk‐adaptive paradigm in the era of biologic precision

CA: A Cancer Journal for Clinicians, Volume 76, Issue 5, September/October 2026.
Abstract The clinical landscape of early stage nonsmall cell lung cancer is at transformative crossroads. Driven by the widespread adoption of low‐dose computed tomography screening, the frequent detection of ground‐glass opacities, and a rising incidence among never‐smokers, the diagnostic center of gravity has shifted toward earlier, potentially ...

Sudden Respiratory Impairment due to Simultaneous Airway Obstruction and Tension Pneumothorax in a Patient Who Underwent Tracheostomy

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT An 86‐year‐old woman with a tracheostomy developed airway obstruction caused by viscid sputum. Forceful manual ventilation through her obstructed airway precipitated tension pneumothorax, pneumomediastinum, pneumopericardium, pneumoperitoneum, and pneumoretroperitoneum.
