Three-dimensional glenohumeral relationship in cuff tear arthropathy and its correlation with the type of cuff tear.

Objective: The main purpose of this study is to evaluate 1) the three-dimensional (3D) glenohumeral relationship in cuff tear arthropathy (CTA) and 2) the correlation between different types of rotator cuff tears (RCTs) and the 3D glenohumeral relationship.

Method: A total of 124 patients with CTA and 60 control patients were included in this study. 3D models of computed tomography images of the shoulder were reconstructed to evaluate the position of the humerus in relation to the scapula using a Cartesian coordinate system.

Antibiotic resistance in the microbiota of periodontitis patients: an update of current findings.

Systemic antibiotics are an effective adjunct in the treatment of periodontitis, but their judicious use is necessary as antimicrobial resistance is a growing global concern. This review aims to explore the current understanding and insight related to antibiotic resistance in the subgingival microbiota of periodontitis patients. A search of MEDLINE (PubMed) was carried out from 1 January 2012 to 25 November 2021 for studies related to antibiotic resistance in periodontitis patients.

Limited value of current shoulder arthroplasty registries in evidence-based shoulder surgery: a review of 7 national registries.

National shoulder arthroplasty registries are currently used to assess incidence, indication, type of prosthesis and revision, but they seem to lack sufficient information to lead to evidence based decision-making in shoulder surgery. There appears to be a large difference in registered parameters and outcome measurement per country. First we investigated whether existing registries have sufficient common datasets to enable pooling of data.

Managing a Renal Transplant Programme During the COVID-19 Pandemic: Practical Experience from a Singapore Transplant Centre.

Introduction: Coronavirus Disease 2019 (COVID-19) has significantly affected the way healthcare is delivered in Singapore. Healthcare services such as renal transplantation had to rapidly adjust and meet the needs to (1) protect patients and staff, (2) ramp up, conserve or redeploy resources while (3) ensuring that critical services remained operational. This paper aims to describe the experience of the renal transplant programme at the Singapore General Hospital (SGH) in responding to the risks and constraints posed by the pandemic.

Teaching hip surgery to orthopaedic residents: what's new?

Purpose: The purpose of this study is to provide an overview of the published literature on the existing educational methods used to teach surgical skills, with a specific focus on hip surgery, to orthopaedic residents.

Methods: A total of 31 articles were selected from a PubMed literature search on the topic of teaching surgical skills to orthopaedic residents, and 9 articles on hip surgery are included in this review.

Results: Although several methods are included in the published literature to teach orthopaedic residents, only arthroscopy of the knee and shoulder joint is well described.
