Infectious Bronchiolitis Infectious bronchiolitis is characterized histologically by a pattern of acute bronchiolar injury, with epithelial necrosis and inflammation of the bronchiolar walls and intraluminal exudates [ 1] (Fig. 5). Lymphoplasmacytic bronchiolar wall infiltrates with neutrophil-rich intraluminal exudates are seen It is characterized histologically by a pattern of acute bronchiolar injury, with epithelial necrosis and inflammation of the bronchiolar walls and intraluminal exudates. There can also be edematous change and fibrosis within bronchiolar walls. Etiology. viruses. respiratory syncytial virus (RSV): particularly in children (RSV bronchiolitis

Bronchiectasis typically results from recurrent infection and inflammation that cause irreversible bronchial dilatation and imply chronicity of disease (9). In consequence, bronchiectasis is not always present in the setting of small airways disease (eg, acute infectious bronchiolitis) Bronchiolitis generically refers to inflammation and/or fibrosis involving (a) airways smaller than 2 mm in diameter, which often lack a cartilaginous wall, and/or (b) the alveolar ducts (1). Although the term bronchiolitis is commonly used by radiologists, pathologists, and other clinicians, its meaning may be somewhat different for each specialty

Chronic bronchitis most often results from overproduction and hypersecretion of mucus by goblet cells. The mechanism is not entirely clear but is linked to both hypertrophy of submucosal glands ( Reid index ) and increased number of goblet cells which are thought to be the protective reaction to tobacco smoke or other pollutants 4 Acute bronchitis, also known as a chest cold, is short-term bronchitis - inflammation of the bronchi (large and medium-sized airways) of the lungs. The most common symptom is a cough. Other symptoms include coughing up mucus, wheezing, shortness of breath, fever, and chest discomfort. The infection may last from a few to ten days Acute bronchitis is the result of acute inflammation of the bronchi secondary to various triggers, most commonly viral infection, allergens, pollutants, etc. Inflammation of the bronchial wall leads to mucosal thickening, epithelial-cell desquamation, and denudation of the basement membrane Background: Bronchial thermoplasty (BT) is a novel treatment for severe asthma based on radiofrequency energy delivery to the larger airways. Although impressive radiological abnormalities have been reported, the incidence, pattern, and behavior over time of acute radiological abnormalities following BT are not well established Acute bronchitis is a clinical diagnosis characterized by cough due to acute inflammation of the trachea and large airways without evidence of pneumonia. Pneumonia should be suspected in patients..
