Optimizing genetic testing strategy for suspected attenuated adenomatous polyposis: effective solutions in public health systems.

Background: APC and MUTYH genes are key in hereditary attenuated adenomatous polyposis syndromes. Guidelines recommend genetic testing based on polyp count, often overlooking age despite its impact on polyp prevalence.

Aim: To enhance genetic testing strategies for suspected attenuated adenomatous polyposis by combining polyp count and age in a probability calculator.

Falciform ligament thrombosis after umbilical vein recanalization in the setting of acute pancreatitis, a rare entity.

We present the case of a 79-year-old man who presents falciform ligament thrombosis after umbilical vein recanalization as an uncommon complication of acute pancreatitis. The performance of abdomino-pelvic CT with contrast, allowed its diagnosis, as well as the establishment of an adequate treatment with favorable evolution.

[Pancreatic cancer screening in a clinical practice setting: it is the moment of Prevention].

Pancreatic cancer surveillance can improve outcomes in high-risk individuals. However, little is known about its applicability and findings in routine clinical practice. Our aim was to evaluate findings on screening tests in high-risk individuals in a clinical practice setting and to analyze factors associated with the presence of relevant pancreatic lesions.

Diagnosis and clinical behavior in patients with Lynch-like syndrome.

Introduction And Aims: Lynch-like syndrome is diagnosed when there is an expression deficit in DNA mismatch repair proteins but a normal genetic study. The behavior and management of that pathology are currently a subject of debate. We present herein the characteristics of patients with Lynch-like syndrome, together with a surveillance proposal.

Factors related to colorectal cancer in advanced adenomas and serrated polyps: a further step toward individualized surveillance.

Aim: The risk of presenting synchronous or metachronous neoplasm, either adenoma or carcinoma, increases after an initial colonic lesion develops. It is known as tumor multicentricity and constitutes the rationale for surveillance programs. This study was designed to identify the clinical, pathologic, and molecular features related to previous or synchronous colorectal cancer (CRC) in patients with advanced adenomas (AA) or serrated polyps (SP).

Long-term remission with rituximab in a patient with severe hepatitis C virus-induced mixed cryoglobulinemia.

Mixed cryoglobulinemia (MC) is a small-vessel systemic vasculitis characterized by the presence of cryoglobulins, immunoglobulin complexes that precipitate at low temperatures ( < 37 ºC) inducing the inflammatory process. The most frequent etiology is hepatitis C infection (HCV) (1). Rituximab (RTX), an anti-CD20 monoclonal antibody, has recently emerged as the treatment of choice for severe MC (2).

[Percutaneous radiofrequency ablation with artificial ascites for hepatocellular carcinoma adjacent to the diaphragm].

Surgical resection is the first-line curative treatment of hepatocellular carcinoma (HCC). However most patients are unable to undergo surgical resection because of advanced tumoral stage, severe liver dysfunction or poor clinical status. Therefore, image-guided tumor ablation techniques have been introduced for the treatment of unresectable HCC.

Chronic hepatitis C treatment in a cystic fibrosis patient in the pulmonary pre-transplant stage.

The standard treatment of chronic hepatitis C, pegylated interferon and ribavirin (pegI/R), has many limitations in both effectiveness and secondary effects, which makes it unsuitable or even contraindicated for some patients. In hepatitis C virus-infected cystic fibrosis patients this treatment could increase respiratory infections with subsequent pulmonary function deterioration. On the contrary, hepatitis C virus (HCV) infection may make lung transplant (LT) unfeasible.

[Gastric adenocarcinoma in young adults; comparative study with older patients].

Background: Gastric adenocarcinoma (GA) has been considered a disease of elderly age and has been rarely reported in patients younger than 35 years of age. The aim of thisΩ demographic, clinicopathological and prognosis of gastric cancer in young patients and to compare their features with the behavior in elder adults.

Methods: Between 1993 and 2008, 1536 patients with GA were enrolled in a retrospective database.

Acute spontaneous tumor lysis syndrome in a patient with Crohn's disease taking immunosuppressants.

Acute tumour lysis syndrome (TLS) is a catastrophic complication of the treatment of certain neoplastic disorders. It most commonly occurs in association with hematologic malignancies and appears a few hours to a few days after initiation of specific chemotherapy, as the result from the release of intracellular components into the bloodstream due to abrupt malignant cell death. Acute spontaneous TLS is rare, and it has been described in leukemia and lymphoma and in some patients with solid tumors prior to institution of therapy.
