Diffuse Parenchymal Lung Disease: Classification and.
Pulmonary hypertension (PH) is an end result of a diverse array of complex clinical conditions that invoke hemodynamic and pathophysiological changes in the pulmonary vasculature. Many patients’ symptoms begin with dyspnea on exertion for which screening tests such as chest roentgenograms and more definitive noninvasive tests such as CT scans are ordered initially.
What every physician needs to know Asthma is a chronic inflammatory disease of the airways characterized by at least partially reversible airway obstruction and bronchial hyper-responsiveness. The cause of asthma remains unknown; clearly, both genetic and environmental influences are important. Recent research indicates that asthma is a heterogeneous disease with several phenotypes that likely.

However, in the current hypothesis regarding the pathogenesis of idiopathic pulmonary fibrosis (IPF), exposure to an inciting agent like (tobacco) smoke, environmental pollutants, environmental dust, viral infections, wood and metal dust, gastroesophageal reflux disease or chronic aspiration in a vulnerable host may lead to the initial alveolar epithelial injury.

Due to the small amount of alveolar tissue in transbronchial biopsy (TBB) by forceps, the diagnosis of diffuse, parenchymal lung diseases (DPLD) is inherently problematic, with an overall low yield. The use of cryotechnique in bronchoscopy, including TBB by cryoprobe, has revealed new opportunities in the endoscopical diagnosis of malignant and non-malignant lung diseases.
