Loss of EIF4G2 mediates aggressiveness in distinct human endometrial cancer subpopulations with poor survival outcome in patients.

The non-canonical translation initiation factor EIF4G2 plays essential roles in cellular stress responses via translation of selective mRNA cohorts. Currently there is limited and conflicting information regarding its involvement in cancer development and progression. Here we assessed its role in endometrial cancer (EC), in a cohort of 280 EC patients across different types, grades, and stages, and found that low EIF4G2 expression highly correlated with poor overall- and recurrence-free survival in Grade 2 EC patients, monitored over a period of up to 12 years.

Complete digital pathology transition: A large multi-center experience.

Introduction: Transitioning from glass slide pathology to digital pathology for primary diagnostics requires an appropriate laboratory information system, an image management system, and slide scanners; it also reinforces the need for sophisticated pathology informatics including synoptic reporting. Previous reports have discussed the transition itself and relevant considerations for it, but not the selection criteria and considerations for the infrastructure.

Objective: To describe the process used to evaluate slide scanners, image management systems, and synoptic reporting systems for a large multisite institution.

Tissue microarrey: a potential cost-effective approach for mismatch repair testing in colorectal cancer.

Background: Deficiencies in Mismatch Repair (MMR) proteins are one of the major pathways in the development of colorectal cancer (CRC). MMR status evaluation is recommended in every new CRC patient. However, this is not fully implemented due to high costs.

Potential di-genic contribution to guttate leukoderma as the predominant feature of epidermolysis bullosa simplex.

Inherited epidermolysis bullosa (EB) simplex is a heterogeneous group of skin fragility disorders caused by mutations in genes encoding cell-cell or cell-matrix adhesion proteins. A recently identified, rare subtype of EB simplex is due to bi-allelic mutations in the EXPH5 gene, which encodes exophilin5, an effector protein of the Rab27B GTPase involved in intracellular vesicle trafficking and exosome secretion. The EXPH5 EB subtype is characterized by early-onset skin blisters and scars, mainly on extremities, and varying degrees of pigmentary alterations.

Indolent T-cell lymphoproliferative disease of the gastrointestinal tract after treatment with adalimumab in resistant Crohn's colitis.

We report a case of intestinal indolent T-cell lymphoproliferative disease (TCLPD) occurring after the initiation of tumor necrosis factor-α (TNF-α) inhibitor therapy for resistant Crohn's disease. A prominent T-cell infiltrate positive for CD8, TIA-1, and T-cell receptor-βF1 was associated with the foci of active inflammation. T-cell receptor gene clonality studies (BIOMED-2) demonstrated monoclonality.
