Performance of sentinel lymph node biopsy after neoadjuvant chemotherapy in clinically node positive breast cancer patients: systematic review and meta-analysis.

Background: The reliability of sentinel lymph node biopsy (SLNB) after neoadjuvant chemotherapy (NACT) in patients with initially node-positive breast cancer is still controversial. This meta-analysis is conducted to investigate the feasibility and accuracy of SLNB after NACT in patients with initially positive axillary nodes.

Methods: We conducted a literature search using Medline, PubMed, Embase, Central, and SCOPUS up until April 2021 for studies on the performance of SLNB following NACT.

Orbital textiloma: Two case reports and a literature review.

Purpose: This report presents two cases of orbital textiloma resulting from retained surgical gauze.

Case Description: Both patients presented with postoperative orbital inflammation unresponsive to medical treatment: one eight weeks after excision of an orbital cavernous hemangioma, and the other six months following surgical repair of an orbital floor fracture. CT scans of the orbit revealed well-defined lesions with a heterogeneous center.

Long-term clinical outcomes of isolated orbital floor fracture reconstruction using nonresorbable implants.

Purpose: There are no universally established guidelines for material selection in orbital wall fracture reconstruction. With an increasing preference for permanent implants, this study aimed to compare the long-term clinical outcomes of three different non-resorbable materials in reconstructing isolated orbital floor fractures.

Design: A retrospective, interventional comparative study.

Retention of CAD-CAM locator retentive attachment insert in mandibular implant overdenture.

Background: The continuous development in digital prosthodontics allowed the customization of attachments and retentive inserts which offers an easy and cheap solution for regular maintenance of locator overdentures during daily practice. The present study compared the change in retention values of the fully digitally manufactured custom-made locator attachment retentive insert with the ready-made ones after insertion, removal, and masticatory cycles.

Methods: A complete denture was constructed over a mandibular edentulous epoxy model.

Assessing the value of computed tomography (CT) of the chest in the follow-up of patients with intrahepatic cholangiocarcinoma.

Background: Following tumor resection, imaging recommendation for the follow-up of patients with intrahepatic cholangiocarcinoma (IHCCA) include frequent chest, abdomen and pelvis computed tomography (CT) imaging. The appropriateness of additional imaging studies is usually derived from their clinical utility. The purpose of this work is to determine the value of chest CT imaging in the follow-up of patients with IHCCA.
