Development of a synthetic phantom for the selection of optimal scanning parameters in CAD-CT colonography [PDF]

, 2006
The aim of this paper is to present the development of a synthetic phantom that can be used for the selection of optimal scanning parameters in computed tomography (CT) colonography. In this paper we attempt to evaluate the influence of the main scanning

Organ‐sparing strategies in patients with MSI/dMMR tumors including Lynch syndrome: Current state of the art and future perspectives for clinical decision‐making

International Journal of Cancer, EarlyView.
Abstract Deficiency in DNA mismatch repair (dMMR) is a common pathway of carcinogenesis across different tumor types and confers a characteristic microsatellite instability‐high (MSI‐H) molecular phenotype. The MSI‐H/dMMR phenotype may arise from an inherited pathogenic variant in the context of Lynch syndrome and is most frequently observed in ...

A multilevel perspective on MSH6‐associated Lynch syndrome: Integrating molecular, biological, and clinical insights

International Journal of Cancer, EarlyView.
Abstract Lynch syndrome (LS) is the most common hereditary colorectal cancer syndrome, caused by a germline pathogenic variant in one of the mismatch repair (MMR) genes. Among these, MSH6‐associated LS represents a distinct subtype with unique molecular and clinical characteristics.

“Obscure” Appendiceal Orifice Polyps Can Be Challenging to Identify by Colonoscopy

Case Reports in Gastroenterology, 2020
The primary purpose of screening colonoscopy is the detection and subsequent removal of precancerous polyps. However, effective recognition of appendiceal lesions with a standard endoscope is often challenging and is limited to the base of the cecum and ...

Menetrier's: A pediatric chronic state of disease with a possible heritable form

JPGN Reports, EarlyView.
Abstract Menetrier's disease (MD) is a rare, typically transient, hypertrophic gastropathy with under 1000 adult cases and 50 pediatric cases known worldwide. Pediatric cases most often present with an infectious etiology. We present a case of a teenage male expressing a chronic state of disease without infectious origin.
