Non-colorectal intestinal tract carcinomas in inflammatory bowel disease: resul...

Patients with inflammatory bowel diseases (IBD) have an excess risk of certain gastrointestinal cancers. Much work has focused on colon cancer in IBD patients, but comparatively less is known about other more rare cancers. The European Crohn's and Colitis Organization established a pathogenesis workshop to review what is known about these cancers and formulate proposals for future studies to address the most im...

High-frequency oscillatory ventilation in children: a 10-year experience

OBJECTIVES: The aim of the study was to describe the experience with high-frequency oscillatory ventilation (HFOV) in a Portuguese Pediatric Critical Care Unit, and to evaluate whether HFOV allowed improvement in oxygenation and ventilation. METHODS: This was a retrospective observational cohort study of children ventilated by HFOV between January, 2002 and December, 2011. The following parameters were recorde...

Validation of a PNA-FISH method for the detection of Helicobacter pylori

Here, we evaluated a previously established peptide nucleic acid-fluorescence in situ hybridization (PNA-FISH) method as a new diagnostic test for Helicobacter pylori clarithromycin resistance detection in paraffin-embedded gastric biopsy specimens. Both a retrospective study and a prospective cohort study were conducted to evaluate the specificity and sensitivity of a PNA-FISH method to determine H. pylori cla...

Gastric cancer: an opportunity for prevention

Non-invasive ventilation in acute respiratory failure in children

BACKGROUND: There is only sparse data on the use of non-invasive ventilation (NIV) in acute respiratory failure (ARF) in infants and children. For this setting we investigated feasibility and efficacy of NIV and aimed to identify early predictors for treatment failure. PATIENTS AND METHODS: Retrospective chart review was performed for all patients treated with NIV for ARF from 2003 to 2010 on an 8-bed pediatric...

A multicenter validation of an endoscopic classification with narrow band imagi...

BACKGROUND AND STUDY AIM: The reliability and external validity of narrow band imaging (NBI) in the stomach have not been described consistently. The aim of the current study was to describe and estimate the accuracy and reliability of a simplified classification system for NBI in the diagnosis of gastric lesions. METHODS: Consecutive patients undergoing NBI endoscopy at two reference centers (n=85, 33% with dy...

Surgical complications in 2000 renal transplants

INTRODUCTION: Renal transplantation is the best treatment for end-stage renal disease. In the last years, we have seen improvements in immunosuppressive treatment, which have allowed patients to experience a better quality of life and graft survival. Nevertheless, surgical complications remain important problems that increase morbidity, mortality, costs, and hospitalization. Our purpose was to evaluate surgical...

Intra-gastric ballon in the treatment of morbid obesity.

Intragastric balloon is a temporary treatment for weight loss with proven safety and efficacy when associated with lifestyle intervention. It is indicated in the super--obese who are candidates for bariatric surgery to lose weight and to reduce their high surgical risk. Our aim was to retrospectively evaluate the results of the patients in whom this device was inserted during a three-year period from the beginn...
