Transcription factor CUX1 is required for intestinal epithelial wound healing and targets the VAV2-RAC1 Signalling complex.

Intestinal epithelial cells form a protective barrier in limiting gut luminal content potentially harmful to the host. Upon gut epithelium injury, several signals instruct epithelial cells to undergo a rapid healing process. Defects in this process induce inflammatory responses and can further evolve into chronic gut inflammatory diseases.

[Excision by video-thoracoscopy of a mediastinal bronchogenic cyst. A case report].

A 42 year-old man was referred to surgery because of a symptomatic posterior mediastinal mass. Ablation was successfully performed via a video-thoracoscopic procedure avoiding a thoracotomy. The post-operative diagnosis was a bronchogenic cyst, as was the pre-operative diagnosis.

Double-lung transplantation using donor lungs with a right tracheal bronchus.

A 58-year-old man underwent sequential bilateral lung transplantation. On the donor heart-lung block, it was discovered that the right apical segment was supplied by a tracheal bronchus. After the separate implantation of both lungs, a right apical segmentectomy was performed and the postoperative course was uneventful.

[Atypical pleural effusion secondary to transdiaphragmatic communication. Apropos of two cases: a chylothorax and a hydrothorax].

We report two cases of pleural effusion in which a subdiaphragmatic cause was noted. In both cases it was necessary to obliterate a defect in the diaphragm via a thoracic incision. In one case, a left chylothorax occurred in a patient with hepatic cirrhosis.

[Value of mediastinoscopy in the preoperative evaluation of non-small cell lung cancer].

Mediastinoscopy is the most reliable examination to determine the presence or absence of lymph node metastases in the preoperative evaluation of lung cancer extension. It is performed either by the cervical route to explore the peritracheobronchial spaces, or by the anterior route to explore the subaortic and anterior mediastinal spaces. It is carried out immediately before thoracotomy, and the rapid frozen section examination of the lymph nodes is accurate enough to decide whether or not resection should be attempted.
