Successful management of esophageal perforation diagnosed 3 days after injury caused by an explosion in the workplace: report of a case.

We report a case of esophageal perforation caused by an explosion, but which was not diagnosed until 3 days after the injury. A 53-year-old worker sustained superficial dermal burns to his trachea, face, neck, and legs during an explosion. The burns were treated conservatively at a local hospital, but he was transferred to our hospital 3 days after the injury, when mediastinal emphysema and bilateral pleural effusion became evident.

Pulmonary arterial aneurysm with CATCH 22 syndrome--a case report.

An adult case of CATCH 22 syndrome with a pulmonary arterial aneurysm is presented. The chest radiograph showed a large massive lesion, which should be differentiated from lung cancer, mediastinal tumor, or aortic aneurysm. CATCH 22 syndrome is a developmental malformation caused by hemizygous deletion of 22q11 chromosome, which usually presents with cardiac malformation including tetralogy of Fallot, truncus arteriosus, patent arterial duct, and ventricular septal defect.

[Small bowel metastasis from large cell carcinoma of the lung: report of a case].

The case of a 44-year-old man with metastatic tumor of the small intestine from large cell carcinoma of the lung was reported. The patient underwent exploratory thoracotomy because of tumor invasion into the left ventricle. He was discharged from our department after chemotherapy and irradiation.

Spectral analysis of intraluminal pressure in the anastomosed ileal segment of the rat in vitro.

Spectral analysis of the spontaneous intraluminal pressure of the isolated ileal segments in vitro was performed (1) before transection and soon after union (acute model) and (2) until 67 days after anastomosis (chronic model). A single peak was found in the spectral arrays of the acute model before transection. However, more than two peaks were clearly found in spectral arrays of both acutely or chronically anastomosed models.
