Applicability of the Barcelona scale to assess the quality of cleanliness of mucosa at esophagogastroduodenoscopy.

BACKGROUND AND OBJECTIVES: There are few scales with prospective validation for the assessment of the upper gastrointestinal mucosal cleanliness during an esophagogastroduodenoscopy (EGD). The aim of this study was to develop a valid and reproducible cleanliness scale for use during an EGD. METHODS: We developed a cleanliness scale (Barcelona scale) with a score (0-2 points) of five segments of the upper gastrointestinal tract with thorough cleaning techniques (esophagus, fundus, body, antrum, and duodenum). First, 125 photos (25 of each area) were assessed, and a score was assigned to each image by consensus among 7 experts endoscopists. Subsequently, 100 of the 125 images were selected and the inter- and intra-observer variability of 15 previously trained endoscopists was evaluated using the same images at two different times. RESULTS: In total, 1500 assessments were performed. In 1336/1500 observations (89%) there was agreement with the consensus score, with a mean kappa value of 0.83 (0.45-0.96). In the second evaluation, in 1330/1500 observations (89%) there was agreement with the consensus score, with a mean kappa value of 0.82 (0.45-0.93). The intra-observer variability was 0.89 (0.76-0.99). CONCLUSIONS: The Barcelona cleanliness scale is a valid measure and reproducible with minimal training. Its application in clinical practice is a significant step to standardize the quality of the EGD.

Endoscopic diagnosis of H. pylori infection. / Diagnóstico endoscópico de la infección por H. pylori.

Helicobacter pylori (H. pylori) infection is highly prevalent in our environment and is associated with highly relevant gastric disease, both benign and malignant. The gold standard for diagnosis is histological confirmation by biopsy. However, there is increasing evidence that optical endoscopic diagnosis could have a fundamental role in avoiding unnecessary biopsies in certain cases. Specifically, the regular distribution of the collecting venules (RAC pattern) seems to have a high negative predictive value (NPV) to rule out infection. This review describes the most outstanding endoscopic findings with the best diagnostic potential for H. pylori infection after an exhaustive search comparing the most relevant studies that have been carried out in Europe and the East.

Serological levels of IGF-1 and IGFBP-3 in patients with Barrett's esophagus and esophageal adenocarcinoma: Longitudinal study. / Niveles séricos de IGF-1 e IGFBP-3 en pacientes con esófago de Barrett y adenocarcinoma de esófago. Estudio longitudinal.

BACKGROUND: Barrett's esophagus (BE) is an entity with a known histological progression to malignancy. The insulin-like growth factor (IGF) system is involved in the carcinogenesis through obesity-related mechanisms that include IGF and it has been associated with several types of cancer. OBJECTIVES: To evaluate the serological levels of IGF-1 and IGFBP-3 in patients with BE and esophageal adenocarcinoma. PATIENTS AND METHODS: Prospective study of patients with BE and esophageal adenocarcinoma who underwent upper endoscopy between September 2012 and December 2015. A baseline determination of IGF-1 and IGFBP-3 was performed. We included a control group of patients without BE. RESULTS: One hundred sixteen patients were included: 36 controls, 62 with BE (42 without dysplasia and 20 with dysplasia) and 18 with adenocarcinoma. IGF-1 and IGF-1/IGFBP-3 molar ratio showed a progression to high levels in BE and adenocarcinoma than in controls (IGF-1: 135.55±66.07ng/ml, 148.33±81.5ng/ml, 108.19±46.69ng/ml, respectively; P=.049) (molar ratio: 0.23±0.91, 0.29±0.11, 0.19±0.06, respectively; P=.001), without differences between the histological types of BE. Fifty-four out of the 65 patients with BE were followed up (median of 58.50 months, range 12-113) and 11 of them (20.4%) presented progression to low-grade dysplasia (n=8) or high-grade dysplasia/adenocarcinoma (n=3), without differences in the IGF system compared with patients without progression. CONCLUSIONS: Patients with BE and esophageal adenocarcinoma have changes in the IGF system although the serological levels of IGF-1 and IGFBP-3 do not correlate with histological progression of BE.

Enfermedad de Wilson: consideraciones para optimizar el seguimiento a largo plazo / Considerations for optimizing Wilson's disease patients’ long-term follow-up

La enfermedad de Wilson es una patología genética multiorgánica causada por la acumulación excesiva de cobre en el organismo. La afectación hepática es la inicial y principal, y puede suponer desde una hepatitis leve y transitoria, hasta el debut en forma de cirrosis o insuficiencia hepática aguda grave. En el seguimiento, hasta un 20-30% de estos pacientes evolucionan a cirrosis hepática. En la práctica clínica, la monitorización de la fibrosis hepática se realiza mayoritariamente mediante métodos indirectos y no invasivos (analíticas, elastografía hepática, ecografías) a semejanza de otras hepatopatías crónicas más prevalentes. No obstante, a pesar de que la elastografía constituye una herramienta de gran valor, la evidencia de su utilidad en Wilson es muy limitada. En esta revisión se repasa la información disponible y sus limitaciones para el seguimiento de la enfermedad de Wilson.

Wilson's disease is a sistemic genetic disease caused by the excessive accumulation of copper. The first and main involvement is in the liver, which can range from mild and transient elevation of transaminases to the onset of an overt cirrhosis or acute liver failure. It is known that up to 20-30% of these patients may evolve to liver cirrhosis during follow-up. In clinical practice, liver fibrosis is assessed mainly by using indirect and non-invasive tools (laboratory tests, liver elastography, ultrasound), similar to other prevalent chronic liver diseases. However, despite the fact that liver elastography is a valuable tool in general hepatology, the evidence of its usefulness and accuracy in Wilsońs disease is scarce. This review summarizes the available scientific data and their limitations in Wilson's disease.

Objetivos: Estudiar la asociación entre el nivel de albúmina sérica y las alteraciones de los electrolitos, gasessanguíneos y compuestos nitrogenados en adultos incidentes del servicio de emergencia de un hospital general.Material y métodos: Se incluyeron 275 pacientes que acudieron a la emergencia del Hospital Cayetano Herediaen Lima, Perú entre el 2013 y el 2015 a quienes el médico tratante solicitó al ingreso electrolitos séricos, gasessanguíneos y albúmina sérica. Se contrastó la albúmina como variable ordinal contra los electrolitos, gases arteriales,urea, calcio y fósforo séricos. También se analizó mediante análisis bivariado la albúmina normal (>3,5 g/dl) y lamuy baja (<2,5 g/dl) contra la variables antes mencionadas y la existencia de correlación lineal entre los valoresnuméricos continuos de las diferentes variables con la albúmina sérica...

Objectives: To evaluate the association between serum albumin and abnormalities in serum electrolytes, bloodgases and nitrogen compounds in adult patients attending an emergency room of a general hospital. Methods: 275patients who attended the emergency room of Hospital Cayetano Heredia en Lima, Peru between 2013 and 2015were included in the study. Serum albumin (ordinal values) was contrasted with serum electrolytes, blood gases,urea, and serum calcium and phosphorus. Normal albumin (>3.5 g/dl) and low albumin (<2.5 g/dl) were contrastedwith the above-mentioned variables using bivariate analysis, and numeric values of these variables were correlatedwith serum albumin with lineal correlation...
