Histiocytic pleural effusion: the strong clue to malignancy.

Background: There have been many studies on the clinical characteristics of neutrophilic, lymphocytic, and/or eosinophilic pleural effusion. While caring for patients with pleural effusion, we found that histiocytic pleural effusion (HisPE) was not uncommon. However, few studies have explored HisPE.

The mechanical characteristics and performance evaluation of a newly developed silicone airway stent (GINA stent).

Central airway obstruction (CAO) can be attributed to several benign or malignant conditions. Although surgery is the preferred therapeutic option for the management of CAO, bronchoscopic treatment can be performed in scenarios where the surgical procedure is not possible. Recent years have witnessed several improvements in the field of bronchoscopic treatment, especially with regard to airway stents.

Clinical Importance of Work-Exacerbated Asthma: Findings From a Prospective Asthma Cohort in a Highly Industrialized City in Korea.

Purpose: Work-related asthma (WRA) occupies about 10%-30% of all asthma cases. Among 2 subtypes of WRA (occupational asthma [OA] and work-exacerbated asthma [WEA]), the rate of WEA has been reported to increase recently. WRA is described as having worse characteristics than non-WRA (NWRA), while WEA is known to show similar severity to OA in terms of symptoms and exacerbations.

Large Endobronchial Hamartoma Successfully Resected by Snare Through Flexible Bronchoscopy.

Benign pulmonary tumors are rare, composing less than 1% of pulmonary tumors; of these, hamartomas are the most common. Endobronchial hamartomas are rarer still, composing 1.4% of all pulmonary hamartomas.
