Extraction vs nonextraction of premolars for orthodontic treatment: A scoping review examining the extent, range, and characteristics of the literature.

Introduction: The debate about whether malocclusion can or should be treated with or without extraction of premolars continues. This scoping review quantifies the literature, summarizes the outcomes researched and methods, and proposes a way to reduce uncertainty in this area.

Methods: Electronic and gray literature searches were undertaken without language restriction, but non-English language titles and abstracts were not translated.

A comparison of post-op haemoglobin levels and allogeneic blood transfusion rates following total knee arthroplasty without drainage or with reinfusion drains.

The effects of re-infusion drains on the rate of allogeneic blood transfusion and post-op haemoglobin levels in Total Knee Arthroplasty were examined. A group of 22 patients undergoing primary Total Knee Arthroplasty using a CBCII Constavac Stryker re-infusion drainage system were compared with a group of 30 patients, matched for age, sex and type of prosthesis but without any drain usage. The re-infusion drain.

Bilateral ankylosis of the jaw treated with total alloplastic replacement using the TMJ concepts system in a patient with ankylosing spondylitis.

Minimal documentation exists regarding bilateral temporomandibular joint (TMJ) involvement in ankylosing spondylitis (AS) and surgical management of this specific manifestation. Use of TMJ concepts prostheses in AS patients has not been previously described. This case demonstrates that TMJ replacement with prosthetic joints in AS is technically possible and appropriate.
