Change in physical activity related to admission for exacerbation in COPD patients.

Introduction: The aim of this study was to determine the impact of hospitalizations on levels of physical activity (PA) and whether other factors were associated with subsequent changes in PA.

Methods: Prospective observational cohort study with a nested case-control study, with follow-up 60 days from the index hospital admission. Nine hospitals participated in the study.

[Epithelioid hemangioendothelioma: an uncommon liver tumor].

We report the case of a female patient who was referred to our unit because of a solid liver tumor, suggestive of metastasis. After biopsy, the patient was diagnosed with epithelioid hemangioendothelioma of the liver. Epithelioid hemangioendothelioma is a rare entity with an unpredictable, potentially fatal, clinical course and outcome.

Combined liver transplantation plus imatinib for unresectable metastases of gastrointestinal stromal tumours.

Therapeutic options for treating unresectable hepatic metastases of leiomyosarcomas were scarce until a few years ago. Recent advances in the study of the biology of intestinal tumours have radically changed our knowledge of their pathogenesis. Many of the tumours previously considered as leiomyosarcomas are now identified as gastrointestinal stromal tumours (GISTs).

De novo internal neoplasms after liver transplantation: increased risk and aggressive behavior in recent years?

The goal of the study was to determine the incidence and variables associated with post-liver transplantation (LT) de novo internal neoplasms development, excluding skin tumors and hepatocellular carcinoma. Medical records were reviewed for recipient/donor demographics, viral serology, cause of liver disease, interval from LT to tumor diagnosis, predisposing factors, immunosuppression and survival. Forty-one neoplasms (31 solid and 10 hematologic) developed in 772 recipients (5.

Budd-Chiari syndrome caused by membranous obstruction of the inferior vena cava associated with coeliac disease.

Ten cases of Budd-Chiari syndrome associated with coeliac disease have been reported in the literature, most of them in North African subjects. Supporting this association, we report a new case in a young Spanish Caucasian man in whom the cause of the syndrome was the membranous obstruction of the inferior vena cava, an infrequent cause of Budd-Chiari syndrome in Western countries. A percutaneous balloon angioplasty was performed, with satisfactory outcome.
