[Utility of abdominal ultrasonography in the management of ulcerative colitis:proposal of a new scoring system].

In the management of ulcerative colitis (UC), colonoscopy (CS) is considered essential for diagnosis;however, its invasiveness poses a challenge. Conversely, recent advancements in ultrasound diagnostic devices have improved imaging quality for the digestive tract, rendering them valuable in UC management. Therefore, this study aimed to elucidate the correlation between abdominal ultrasonography (AUS) and CS in assessing UC activity.

Improvement of coracoid process union rates: a comparative study of conventional open and arthroscopic-assisted Bristow procedures for treating anterior shoulder instability in rugby players.

Background: The Bristow coracoid transfer procedure is a reliable technique for treating anterior shoulder instability in patients with large glenoid bone loss or those involved in collision sports. However, its success is marred by its inferior bone union rate of the coracoid process as compared to the Latarjet procedure. This study aimed to evaluate whether arthroscopic confirmation of the secured coracoid fixation during the Bristow procedure improves the bone union rate and clinical outcomes as compared to the open procedure.

Prevention of pneumocystis pneumonia in patients with hematological diseases: Efficacy of low-dose atovaquone.

Objective: At our institution, patients with hematological disease who require pneumonia (PJP) prophylaxis were administered atovaquone at a low dose (750 mg/day). However, there have been few reports on the efficacy of low-dose atovaquone administration, and the purpose of this study is, therefore, to investigate its effectiveness.

Materials And Methods: We investigated the expression of PJP in patients with hematological disease who received atovaquone administration.

The prevalence of shoulders with a large glenoid defect and small bone fragment increases after several instability events during conservative treatment for traumatic anterior instability.

Background: Unstable shoulders with a large glenoid defect and small bone fragment are at higher risk for postoperative recurrence after arthroscopic Bankart repair. The purpose of the present study was to clarify the changes in the prevalence of such shoulders during conservative treatment for traumatic anterior instability.

Methods: We retrospectively investigated 114 shoulders that underwent conservative treatment and computed tomography (CT) examination at least twice after an instability event in the period from July 2004 to December 2021.
