BACKGROUND Cervicofacial emphysema may arise due to the leakage of air from a defect in the aerodigestive tract to the fascial layers of neck and face. Rarely, it may be caused by insufflation of air through the Stensen's duct. CASE REPORT We present a case with diffuse facial, cervical and mediastinal emphysema due to playing a wind instrument immediately after a facial trauma. There was no ...
BACKGROUND Chronic obstructive pulmonary disease is a smoking-related disease, and is categorized into the emphysema and airway dominant phenotypes. We examined the relationship between emphysematous changes and epidermal growth factor receptor (EGFR) mutation status in patients with lung adenocarcinoma. PATIENTS AND METHODS The medical records for 250 patients with lung adenocarcinoma were r...
STUDY OBJECTIVE Part 1: To describe cases of emphysema (subcutaneous and/or mediastinal) and pneumothorax after percutaneous dilational tracheostomy (PDT) in a series of 326 patients, and to review the existing literature describing the incidence and possible mechanisms. Part 2: To analyze the potential mechanisms for the development of emphysema and pneumothorax in human cadaver models. DESI...
Emphysema, one of the major components of chronic obstructive pulmonary disease (COPD), is characterized by the progressive and irreversible loss of alveolar lung tissue. Even though >80% of COPD cases are associated with cigarette smoking, only a relatively small proportion of smokers develop emphysema, suggesting a potential role for genetic factors in determining individual susceptibility to...
Predominant emphysema phenotype in chronic obstructive pulmonary disease patients. P. Boschetto, M. Miniati, D. Miotto, F. Braccioni, E. De Rosa, I. Bononi, A. Papi, M. Saetta, L.M. Fabbri, C.E. Mapp. #ERS Journals Ltd 2003. ABSTRACT: Patients with fixed airflow limitation are grouped under the heading of chronic obstructive pulmonary disease (COPD). The authors investigated whether COPD patien...
CO(2) subcutaneous emphysema is one of the complications of laparoscopic surgery using CO(2) gas. During laparoscopic surgery, CO(2) gas can spread to the entire body surface through the subcutaneous tissue layer. Extensive CO(2) subcutaneous emphysema results in hypercarbia and acute respiratory acidosis. Hypercarbia and acidosis can lead to decreased cardiac contractility and arrhythmia. A cl...
Orbital emphysema is typically a benign condition that occurs following forceful injection of air into the orbital soft tissue spaces. In many cases there is a history of trauma and fracture of an orbital bone, which permits air entry. However, other mechanisms of orbital emphysema have been reported including infection, pulmonary barotrauma, injury from compressed-air hoses, and complications ...
