With the development of tissue banking, a need for homogeneous methods of collection, processing, and storage of tissue has emerged. We describe the implementation of a biological bank in a high-volume, tertiary care University referral center for esophageal cancer surgery. We also propose an original punch biopsy technique of the surgical specimen. The method proved to be simple, reproducible, and not expensive. Unified standards for specimen collection are necessary to improve results of specimen-based diagnostic testing and research in surgical oncology.

Predictors for negative large loop excision of the transformation zone (LLETZ) in a primary HPV screened population.

Objective: To assess rates of histologically negative large loop excisions of the transformation zone (LLETZ) and potential predictive factors within a single UK Colposcopy Unit.
Design: Retrospective cohort study SETTING: Jessop Wing Colposcopy Unit, Sheffield, U.K.
Introduction: Previous studies have investigated the density of dermal papillae (DP) in normal skin using reflectance confocal microscopy (RCM), a non-invasive imaging technique that allows a real time, high-resolution imaging of the skin, although no histological confirmation was provided. The aim of the present study was to compare the RCM evaluation of DP density in healthy skin with horizontal histopathological sections (HHS), a technique that provides a horizontal view of the skin.
Methods: Ten adult patients were selected, and a healthy skin area was marked for RCM examination and a subsequent 5-mm punch biopsy that was processed for HHS.
Pan-TRK positive uterine sarcoma in immunohistochemistry without neurotrophic tyrosine receptor kinase gene fusions: A case report.

Background: The classification of uterine sarcomas is based on distinctive morphological and immunophenotypic characteristics, increasingly supported by molecular genetic diagnostics. Data on neurotrophic tyrosine receptor kinase () gene fusion-positive uterine sarcoma, potentially aggressive and morphologically similar to fibrosarcoma, are limited due to its recent recognition. Pan-TRK immunohistochemistry (IHC) analysis serves as an effective screening tool with high sensitivity and specificity for -fusion malignancies.

Department of Clinical Sciences, College of Veterinary Medicine, Columbus, OH, USA.
Background: Rotator cuff repairs may fail because of compromised blood supply, suture anchor pullout, or poor fixation to bone. To augment the repairs and promote healing of the tears, orthobiologics, such a platelet-rich plasma (PRP), and biologic scaffolds have been applied with mixed results. Adipose allograft matrix (AAM), which recruits native cells to damaged tissues, may also be a potential treatment for rotator cuff tears.

A unique case report on campylobacter rectus infection leading to acute motor axonal neuropathy in a pediatric patient. Campylobacter rectus is an anaerobic bacterium found in the oral cavity. While it has been linked to periodontal disease, its association with acute motor axonal neuropathy (AMAN), a variant of Guillain-Barre Syndrome, remains unverified.
