AIM The aim of this study was to determine the pressure where oral soft tissue resistance will be overcome resulting in soft tissue emphysema and to measure the safety of an antifouling device for a videoscope used during minimally invasive periodontal surgery. MATERIALS AND METHODS Resistance was measured in vitro in porcine tissue. One study arm measured palatal tissue resistance to air app...

Boerhaave syndrome (BS) is a spontaneous esophageal perforation and is a life-threating but uncommon disorder. This syndrome involves a transmural perforation and typically occurs after forceful emesis. The prognosis is dependent on rapid diagnosis and correct management. The classic presentation of BS consists of vomiting, subcutaneous emphysema, and lower thoracic pain. However, significant s...

BACKGROUND In patients with heterogeneous emphysema, surgical and bronchoscopic lung volume reduction (LVR) treatments are available. However, for patients with homogeneous emphysema these treatments are hardly investigated and seem less effective. Bronchoscopic LVR coil treatment has been shown to be effective in patients with heterogeneous emphysema, but this treatment has not been exclusivel...

BACKGROUND Lung volume reduction (LVR) techniques improve lung function in selected patients with emphysema, but the impact of LVR procedures on the asynchronous movement of different chest wall compartments, which is a feature of emphysema, is not known. METHODS We used optoelectronic plethysmography to assess the effect of surgical and bronchoscopic LVR on chest wall asynchrony. Twenty-six ...

PURPOSE The outcome of radical surgery for lung cancer was investigated in patients with combined pulmonary fibrosis and emphysema (CPFE). METHODS A retrospective chart review involved 250 patients with lung cancer who underwent pulmonary resection at Tokyo Women's Medical University Yachiyo Medical Center between 2008 and 2012. Based on the status of nontumor-bearing lung evaluated by preope...
