BioGlue and Dermabond save time, leak less, and are not mechanically inferior to two-layer and modified one-layer vasovasostomy.

Objective: To compare operative time, patency, and integrity of glue-assisted versus suture-only vasovasostomies.

Design: A Medline search revealed no vasovasostomy studies testing tissue adhesives other than fibrin. We compare glue-reinforced to suture-only vasovasostomies.

Composite EBV negative peripheral T-cell lymphoma and diffuse large B-cell lymphoma involving the ileum: a case report and a systematic review of the literature.

We report a case of an intestinal peripheral T-cell lymphoma (PTCL) with a concurrent diffuse large B-cell lymphoma (DLBL) involving the ileum and a regional lymph node. The patient presented with an abdominal mass. The terminal ileum showed a diffuse and monotonous population of small CD3-positive T cells.

Death receptor apoptosis signaling mediated by FADD in CD30-positive lymphoproliferative disorders involving the skin.

Background: The CD30-positive lymphoproliferative disorders lymphomatoid papulosis (LyP), primary cutaneous anaplastic large cell lymphoma (C-ALCL), and systemic anaplastic large cell lymphoma (S-ALCL) are lesions that overlap clinically, histopathologically, and immunophenotypically. Their biologic behaviors, however, vary considerably. In particular, lesions of LyP regress spontaneously while those of S-ALCL persist and often progress.

Similar patterns of genomic alterations characterize primary mediastinal large-B-cell lymphoma and diffuse large-B-cell lymphoma.

To address the possible genetic relationship between primary mediastinal large-B-cell lymphoma (PMLBCL) and diffuse large-B-cell lymphoma (DLBCL), we compared DNA copy number changes identified by comparative genomic hybridization (CGH) analysis of 40 PMLBCL and 91 DLBCL tumors. We assessed their karyotypes by G-banding; amplification of MYC, BCL2, and REL genes by Southern blotting; and incidence of nonpolymorphic BCL6 mutations by single-strand conformation polymorphism analysis (SSCP). Overall, CGH identified overlapping and nonoverlapping patterns of DNA copy number changes in the two groups.
