Idiopathic inflammatory myopathies (MII) are a group of autoimmune diseases that mainly affect the proximal muscles. The most common types are Dermatomyositis (DM), Polymyositis (PM), Necrotizing autoimmune myopathy and Inclusion body myositis. Unique forms are identified in their clinical presentation consisting of muscular and extramuscular manifestations, their myopathic alterations in the electromyogram and the elevation of muscle enzymes. However, muscle biopsy remains the gold standard for diagnosis. These disorders are tratable with a proper. The goals of treatment are to eliminate inflammation, restore muscle performance, reduce morbidity and improve quality of life.This review aims at a basic diagnostic approach in patients with suspicion of MMI through its main clinical, laboratory and histopathological findings.

Objective: To determine whether localization and size are related to the presence of high-grade dysplasia of colon adenomas in patients of a Peruvian hospital. Materials and methods: This is a descriptive transversal study. We checked colonoscopy reports of 2014-2015 years of Hospital Daniel Alcides Carrion, we included the polyps found in patients older than 18 years old, and excluded reports from patients with colorectal cancer, an antecedent of oncological surgery, inflammatory bowel disease and polyposis (6 or more). We used data based on localization (proximal and distal colon, based on the splenic angle), size (less than 10 mm and 10 mm or more), shape (pediculate and sessile) and grade of dysplasia (low and high-grade). We calculated the strength of association by OR, and we determined whether there was association by Chi-square test with a significance value less than 0.05. Resul...

Objetivo: Determinar si la localización y el tamaño de los adenomas de colon se asocian con la presencia de displasia de alto grado en los pacientes de un hospital peruano. Materiales y Métodos: Se realizó un estudio trasversal mediante la revisión de informes de colonoscopías de los años 2014-2015 del Hospital Nacional Daniel Alcides Carrión, incluyéndose los pólipos de pacientes mayores de 18 años; y excluyéndose los de pacientes con cáncer de colon, antecedente de cirugía oncológica, enfermedad inflamatoria intestinal y poliposis (6 o más). Se extrajeron los datos de localización (colon proximal y distal, división a partir del ángulo esplénico), tamaño (menos de 10 mm y 10 mm o más), forma (pediculados y sésiles) y grado de displasia (bajo y alto grado). Se calculó la fuerza de asociación mediante OR, se determinó si existía asociación a través de la...
