Complex Interplay of COVID-19 ARDS with Guillain-Barré Syndrome and Cerebral Infarction: A Case Study.

BACKGROUND Coronavirus disease (COVID-19) can cause various complications. We report a case of severe COVID-19 acute respiratory distress syndrome (ARDS) in a patient receiving veno-venous extracorporeal membrane oxygenation (V-V ECMO), complicated by Guillain-Barre syndrome (GBS) and cerebral infarction, as well as pulmonary embolism. CASE REPORT A 55-year-old Japanese man with a history of ulcerative colitis was admitted for COVID-19.

Arthroscopically Assisted Coracoclavicular (CC) Stabilization Using a Suture Button Device for Lateral Clavicle Fractures with CC Ligament Injury.

Lateral clavicle fractures represent approximately 10-15% of all clavicle fractures. However, controversy exists regarding the optimal surgical treatment because of instability associated with the coracoclavicular (CC) ligament injury and a small lateral fragment. The purpose of this study was to evaluate the radiological and clinical outcomes of arthroscopically assisted CC stabilization using a suture button device for lateral clavicle fractures accompanied by CC ligament injury.

The Combined Suture Bridge With Mason-Allen Technique Is Superior to the Conventional Suture Bridge Technique for Arthroscopic Rotator Cuff Repair.

Purpose: To compare clinical results and retear rates between the combined suture bridge with Mason-Allen (SBMA) technique and the conventional suture bridge (SB) technique in patients with full-thickness rotator cuff tears who underwent arthroscopic rotator cuff repair.

Methods: One hundred two patients who underwent arthroscopic rotator cuff repair using the SB technique (n = 50) or SBMA technique (n = 52) for a full-thickness rotator cuff tear and had at least 2 years of follow-up were retrospectively analyzed. Magnetic resonance imaging was performed before surgery and 2 years after to determine preoperative tear size, Goutallier stage, and presence of retear after surgery.

Shear wave elastography correlates to degeneration and stiffness of the long head of the biceps tendon in patients undergoing tenodesis with arthroscopic shoulder surgery.

Background: Tendinopathy of the long head of the biceps (LHB) tendon causes degeneration and changes its stiffness. However, a reliable means of diagnosis has not been established. Shear wave elastography (SWE) provides quantitative tissue elasticity measurements.

The Effect of Vitamin C and -Acetylcysteine on Tendon-to-Bone Healing in a Rodent Model of Rotator Cuff Repair.

Background: Oxidative stress inhibits tendon-to-bone healing after rotator cuff repair. Regulation of oxidative stress has the potential to accelerate this healing, but its mechanism remains unclear.

Purpose: To investigate the effects of reducing oxidative stress by applying antioxidants, such as -acetylcysteine (NAC) and vitamin C (VC), on rotator cuff repair in a rat rotator cuff repair model.
