[Skin manifestations in adults with a liver allograft].

Background: Skin manifestations after liver transplantation are increasing due to long term immunosuppressive therapy along with an increase in patient survival. Several studies have reported dermatologic complications following renal transplant, but few have studied dermatologic problems after liver transplantation.

Aims: To describe the different types of cutaneous lesions encountered in adults receiving a liver allograft.

Impact of minimally invasive surgery in the treatment of esophageal cancer.

Background: Surgical treatment of esophageal cancer is associated to a high morbidity and mortality rate. The open transthoracic or transhiatal esophagectomy are considerably invasive procedures and have been associated to high rates of complications and operative mortality. In this way, minimally invasive esophageal surgery has been suggested as an alternative to the classic procedures because would produce improvement in clinical longterm postoperative outcomes.

Digestive tract reconstitution after failed esophago-gastro or esophago-coloanastomosis.

Background: Severe dysphagia or even aphagia can occur after esophagectomy secondary to necrosis of the ascended organ with severe stricture or complete separation of the stumps. Catastrophic esophageal or gastric disruption drives the decision to "disconnect" the esophagus in order to prevent severe septic complications. The operations employed to re-establish esophageal discontinuity are not standardized and reoperations for re-establishment of the upper digestive transit are a real challenge.

[Hepatitis B virus immunoglobulin on demand to prevent infection recurrence among liver allograft recipients: report of three cases].

Infection recurrence rates among hepatitis B virus infected liver allograft recipients, may be as high as 80%. Immunoprophylaxis with anti HBVgammaglobulin may reduce these rates and improve survival. The dose of anti HBV gammaglobulin that must be used is not clearly defined.

Organizing pneumonia in patients with severe respiratory failure due to novel A (H1N1) influenza.

The authors describe two cases that developed organizing pneumonia (OP) associated with novel influenza A(H1N1) virus. These patients were admitted to intensive care unit (ICU) because of severe respiratory failure. After initial clinical improvement, both patients worsened their condition during their second week of ICU stay, presenting fever, increasing in inflammatory parameters and worsening in oxygen exchange and respiratory mechanics.

Videothoracoscopic management of middle esophageal diverticulum with secondary bronchoesophageal fistula: report of a case.

Middle esophageal diverticulum is rare, but can result in bronchoesophageal fistula. Previous reports have described open surgical techniques to treat esophageal diverticula, but few have evaluated the effectiveness of a videothoracoscopy approach. We report a case of middle esophageal diverticulum associated with bronchoesophageal fistula, managed successfully with videothoracoscopy.

[Gastrointestinal stromal tumors. Review of 15 patients].

Background: Gastrointestinal stromal tumors (GIST) are the most common mesenchymatous tumors of the digestive tract. The pathological diagnosis is based on microscopy and immunohistochemistiy.

Aim: To review the experience of our surgical unit in patients with GIST MATERIAL AND METHODS: Review of medical records of 15 patients (aged 66+/-13 years, 11 women), with a pathological diagnosis of GIST, treated between 1999 and 2005.

[Sclerosing hemangioma presenting as a solitary lung nodule. Report of one case].

Lung sclerosing hemangioma is an uncommon tumor that presents as a solitary asymptomatic nodule and that affects middle age women. It derives from type II pneumocytes. We report a 52 years old female with a solitary lung nodule detected in a chest X ray requested for the diagnosis of an acute respiratory disease.
