Periprosthetic Ulna Fractures Following Aptis Distal Radioulnar Joint Arthroplasty: A Series of Four Cases.

Purpose: This case series presents four cases of periprosthetic ulna fractures following Aptis distal radioulnar joint (DRUJ) arthroplasty to elucidate clinical characteristics, contributing factors, management challenges, and short-term outcomes following this rare complication and to propose prevention and optimal treatment strategies.

Methods: We conducted a retrospective review of 239 Aptis DRUJ prostheses implanted between 2012 and 2022 at a single institution. We identified four cases of periprosthetic ulna fractures and assessed demographics, surgical indications, time to fracture, mechanism of injury, radiographic findings, treatment modalities, associated complications, and outcomes.

Safety of immediate open traumatic extensor tendon repair performed at an emergency department minor procedure room.

Introduction: The superficial location of the extensor tendons makes them particularly vulnerable to lacerations. Patients most commonly present to the emergency department (ED) after these injuries. We aimed to measure the safety of immediate surgical repair of traumatic open extensor tendon injuries in an ED minor procedure room (MPR) under local anesthesia, and the associated post-operative infection and complication rates.

A Comparison of Parenteral and Per-Oral Antibiotic Usage in Pyogenic Flexor Tenosynovitis: A Retrospective Study.

Introduction Pyogenic flexor tenosynovitis (PFT) is a common hand infection that can cause significant morbidity. Although treatment involves surgical debridement and inpatient intravenous (IV) antibiotics, there is a paucity of literature guiding antibiotic use. This study aims to determine if the use of postoperative outpatient oral antibiotics leads to poor outcomes compared to IV antibiotics given in an institutional setting.

Effect of high-intensity focused ultrasound (HiFU) treatment on intraocular pressure and aqueous humour dynamics: 12 -months results.

Purpose: High intensity focused ultrasound (HiFU) is a cyclodestructive therapy for controlling intraocular pressure (IOP) in glaucoma. The mechanism of action is thought to be through destruction of the ciliary epithelium as well as increased uveoscleral outflow. We reviewed the change in aqueous humour dynamics parameters including aqueous humour flow rate, tonographic outflow facility (TOF) and uveoscleral outflow at 12 months.

The Effect of High-Intensity Focused Ultrasound on Aqueous Humor Dynamics in Patients with Glaucoma.

Purpose: To investigate the effects of high-intensity focused ultrasound (HiFU) on aqueous humor dynamics in patients with glaucoma.

Design: Comparative, nonrandomized, interventional study.

Participants: Adult patients with a diagnosis of open-angle glaucoma or ocular hypertension with suboptimal intraocular pressure (IOP) control despite maximum medical treatment who required further IOP optimization.

Intraocular pressure changes following topical ocular hypotensive medications washout.

Background: To review the changes in intraocular pressure (IOP) following topical hypotensive medications washout in patients with primary open angle glaucoma (POAG), ocular hypertension (OHT) and uveitic glaucoma (UG)/OHT.

Methods: The study included 120 patients with POAG, OHT and UG recruited from prospective clinical trials between February 2013 and July 2017. We excluded 20 eyes with IOP of ≤21 mm Hg, 11 eyes with previous incisional surgery and 17 eyes with incomplete data.

Predictors of selective laser trabeculoplasty success in open angle glaucoma or ocular hypertension: does baseline tonography have a predictive role?

Background: The determinants of success of selective laser trabeculoplasty (SLT) in treatment-naïve patients with open angle glaucoma (OAG) and ocular hypertension (OHT) have not been understood fully. Therefore, we have conducted this study to explore the predictors of success.

Methods: This is a retrospective review of a pre-existing database of patients who had received primary SLT at St Thomas' Hospital, London, UK.

Aqueous Humor Dynamics in Uveitic Eyes.

Purpose: To investigate aqueous humor dynamics in uveitic eyes.

Design: Cross-sectional study.

Participants: Patients with recurrent (≥3 attacks) anterior uveitis (now quiescent) and being treated for glaucoma or ocular hypertension (OHT) (Group 1), previous recurrent anterior uveitis (≥3 attacks) without glaucoma or OHT (Group 2), and normal subjects with no ocular problems and IOP < 21 mm Hg at screening (control group; Group 3).

Current Status of Vascularized Composite Allotransplantation.

The field of vascularized composite allotransplantation (VCA) has moved from a highly experimental procedure to, at least for some patients, one of the best treatment alternatives for catastrophic tissue loss or dysfunction. Although the worldwide experience is still limited, progress has been made in translation to the clinic, and hand transplantation was recently designated standard of care and is now covered in full by the British Health System. This progress is tempered by the long-term challenges of systemic immunosuppression, and the rapidly evolving indications for VCA such as urogenital transplantation.

The role of B cell immunity in VCA graft rejection and acceptance.

Vascularized composite allotransplantation (VCA) has emerged as the most recent field of transplantation to offer an alternative treatment for those patients that have failed or are not suitable candidates for conventional therapy. Most of the current clinical experience in this field is with recipients of skin containing grafts such as the face, upper extremity and abdominal wall transplants. Like solid organ recipients, VCA recipients require lifelong systematic immunosuppression to maintain their grafts.

Effect of phacoemulsification on facility of outflow.

Purpose: Phacoemulsification has been shown to reduce intraocular pressure (IOP). The mechanism of action is thought to be via increased trabecular outflow facility. However, studies on the relationship between phacoemulsification and outflow facility have been inconsistent.

Effect of a Sepsis Educational Intervention on Hospital Stay.

Objectives: To evaluate adherence to the sepsis bundle before and after an educational strategy and its impact on hospital stay.

Design: A prospective, analytic, before-and-after study of children with severe sepsis and septic shock who presented to the emergency department.

Setting: Carried out from January to December 2014 in the emergency department of a quaternary care hospital.

Chemical vapor deposition growth of boron-carbon-nitrogen layers from methylamine borane thermolysis products.

This work investigates the growth of B-C-N layers by chemical vapor deposition using methylamine borane (MeAB) as the single-source precursor. MeAB has been synthesized and characterized, paying particular attention to the analysis of its thermolysis products, which are the gaseous precursors for B-C-N growth. Samples have been grown on Cu foils and transferred onto different substrates for their morphological, structural, chemical, electronic and optical characterizations.

Aqueous outflow facility after phacoemulsification with or without goniosynechialysis in primary angle closure: a randomised controlled study.

Background: Goniosynechialysis (GSL) to remove peripheral anterior synechiae (PAS) alongside standard cataract surgery has potential theoretical advantages, Published randomised trials, however, have not shown conclusive functional benefits and aqueous outflow changes following GSL are unknown. This study aimed to compare electronic Shiøtz tonographic aqueous outflow facility (TOF) following phacoemulsification with or without GSL in patients with primary angle closure (PAC) and PAC glaucoma. Secondary outcomes were changes in intraocular pressure (IOP) and use of glaucoma medications.

Total joint arthroplasty of the distal radioulnar joint for rheumatoid arthritis.

Purpose: To evaluate the clinical and radiological results of primary total distal radioulnar joint (DRUJ) replacement as well as reconstruction following ulnar head excision in patients with rheumatoid arthritis (RA).

Methods: Seventeen patients with RA underwent 19 total DRUJ replacement between 2005 and 2011. Mean age at the time of the surgery was 57 years.

Radioscapholunate arthrodesis using low-profile dorsal pi plate.

Radioscapholunate arthrodesis is a desirable method to treat isolated radiolunate arthritis or ulnar translocation of the carpal bones. An intact midcarpal joint is a prerequisite for functional range of motion. Previously, high rates of nonunion were observed with these procedures, as rigid fixation was difficult to obtain with simple Kirschner wires and screws.

Clinical impact of endoscopic ultrasound-fine needle aspiration of left adrenal masses in established or suspected lung cancer.

Introduction: Correct lung cancer staging is pivotal for optimal allocation to surgical and nonsurgical treatment. A left adrenal gland (LAG) mass is found in 5 to 16%, and malignancy preclude surgery. Endoscopic ultrasound (EUS) is superior to other imaging procedures in visualizing LAG, but the impact of EUS-fine needle aspiration (FNA) on tumor, node, metastasis (TNM)-staging, treatment, and survival is unknown.
