Validation of five contemporary prognostication systems for primary pancreatic endocrine neoplasms: results from a single institution experience with 61 surgically treated cases.
Presently, several systems for the prognostication of pancreatic endocrine neoplasms (PENs) exist and the most appropriate classification system has not been clearly defined. This study aims to validate the performance of the 2004 World Health Organization (WHO), European Neuroendocrine Tumor Society (ENETS), Memorial Sloan-Kettering Cancer Center (MSKCC), American Joint Committee for Cancer (AJCC) TNM staging and Bilimoria criteria in a cohort of patients with PENs who underwent surgery at a single institution. ⋯ All five classification systems were useful for the prognostication of surgically treated PENs in our patient cohort.

Influence of screw diameter and number on reduction loss after plating of distal radius fractures.
The current options for plate-screw combinations in volar locking distal radius plates used for the treatment of distal radius fractures are either plates with a single distal screw row or plates with multiple distal screw rows. Additionally, the screws themselves may have either fixed angle locking or polyaxial locking mechanisms. To date, there is no evidence or consensus regarding the optimal plate-screw combination. The aim of this study was to assess the biomechanical behaviour of different plate-screw combinations with respect to total distal screw number, number of distal screw rows and screw projection surface area of the most distal row. ⋯ Additional distal screw rows in volar locking distal radius plates might not add substantially to resistance against loss of reduction in the post-operative period.

Intraoperative radiotherapy in women with early breast cancer treated by breast-conserving therapy.
Previous studies demonstrated the feasibility of intraoperative radiotherapy (IORT) to the primary tumour bed using a miniature electron beam driven X-ray source for early breast cancer. This study aimed to evaluate the feasibility of IORT as a tumour bed boost after whole breast irradiation (WBI) in breast conserving therapy. ⋯ Tumour bed boost using IORT in women with early breast cancer treated with conservative surgery and WBI was shown to be feasibly consistent with previous studies.
