To considerate perforation of duodenal diverticula.

The duodenal diverticulum is a relatively frequent entity whose diagnosis has been increased over time with the development of new diagnostic and exploratory techniques. Periampullary diverticula (PAD) were classified as type 1, 2, or 3 according to the position of the major papilla from the endoscopic view: type 1, the major papilla was located inside of the diverticula; type 2, the major papilla was located at the edge of the diverticula; type 3, the major papilla was located outside of the diverticula. Complications of duodenal diverticula include ulceration, bleeding, perforation and inflammation with intestinal obstruction.

A starry sky image result in a patient with active bleeding due to malignancy cause.

Hemostatic powders (HP) are increasingly used to address limitations in conventional endoscopic techniques for gastrointestinal bleeding. HP is a relatively recent addition to the arsenal of hemostatic endoscopic procedures (HEPs) for gastrointestinal bleeding (GIB) due to benign and malignant lesions, which all life-threatening conditions. HP acts as a mechanical barrier and/or promotes platelet activation and coagulation cascade.

Liver enzyme alteration in response to dengue virus.

Infectious diseases are extremely important in the global health landscape, specifically dengue and its severe forms. Clinical characterization is very variable due to the wide spectrum of manifestations the virus induces. Dengue is a viral infection caused by the dengue virus and is transmitted to humans by mosquitos of the Aedes family.

Immune checkpoint inhibitor-mediated colitis in a patient with epidermoid metastatic lung cancer: new and emerging toxicities.

In recent years, the development of immunotherapy has been stablished with monoclonals antibodies against control immune molecules in T lymphocytes, tumor cells and other cells, which block lymphocyte activation and suppress immune response. These molecules are Cytotoxic T-Lymphocyte Antigen 4 (CTLA-4) and Programmed Death-ligand 1 (PD-1). Despite clinical benefits, these therapies are not exempt from side effects known as immune-related adverse events (irAEs).

[Hepatitis C patients' record in the Sentinel Units for viral Hepatitis in Argentina 2007- 2014. Distribution by year of birth].

Recommendations for Hepatitis C screening based on risk factorsfor transmission proved to be ineffcient. Accordingly, the CDC recommended to screen all American individuals born between 1945-1965, based on data from population prevalence of infection. The effectiveness of implementing these recommendations in other contexts and/or populations can be estimated, in principle, knowing the age distribution of infected individuals.
