In maxillofacial surgery, tracheostomy is indicated in congenital, inflammatory, oncologic, or traumatic respiratory obstruction. In traumatic cases, however, it is sometimes hard to implement. We describe subcutaneous emphysema following emergent su...
Background: Chronic obstructive pulmonary disease (COPD) and lung cancer are the leading causes of death globally, which share common risk factors such as age and smoking exposure. In high-income countries, low-dose computed tomography (LDCT) lung ca...
Alveolar type II (ATII) cells are progenitors in alveoli and can repair the alveolar epithelium after injury. They are intertwined with the microenvironment for alveolar epithelial cell homeostasis and re-epithelialization. A variety of ATII cell nic...
Background: Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide. In addition to chronic bronchitis and emphysema, patients often develop at least mild pulmonary hypertension (PH). We previously demonstrated that...
We describe the case of a 61-year-old male patient, in which the search for the cause of chronic respiratory failure, severe pulmonary hypertension and secondary erythrocytosis resulted in a diagnosis of combined pulmonary fibrosis and emphysema (CPF...
Background: Chronic obstructive pulmonary disease has extrapulmonary manifestations, such as cardiovascular diseases and osteoporosis. The purpose of this research was to determine the relationship between the type and extent of emphysema with thorac...
Pulmonary emphysema, the main component of chronic obstructive pulmonary disease, is a chronic lung inflammatory disease characterized by the loss of lung elasticity and impaired gas exchange due in large part to the destruction of alveolar walls. Ci...
Cannabis can be related to respiratory diseases, but the relationship between smoking marijuana and the development of a pneumothorax has scarcely been investigated. We aimed to analyze, in patients with a history of cannabis smoking abuse submitted...
Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, and emphysema is present in the majority of affected patients and can be identified on computed tomography (CT). This study investigated whether radiomic feat...
Pulmonary emphysema is a fatal lung disease caused by the progressive thinning, enlargement and destruction of alveoli that is closely related to inflammation and oxidative stress. Oxymatrine (OMT), as a bioactive constituent of traditional Chinese h...
