[A Case of Duodenal Cancer with a History of Metachronous Multiple Colorectal Cancer Resections Achieving Endoscopic Complete Response following Pembrolizumab Treatment].

A male in his 80s with a history of multiple colorectal cancer resections underwent an upper gastrointestinal endoscopy for anemia investigation, which revealed a non-ampullary duodenal carcinoma. Due to insufficient surgical tolerance for pancreaticoduodenectomy, pharmacotherapy was considered. With informed consent, an MSI test was conducted, showing MSI-high, leading to the initiation of pembrolizumab treatment.

Nanothin Descemet stripping automated endothelial keratoplasty performed on a lacerated cornea after globe rupture: a case report.

Background: When performing corneal endothelial transplantation, the presence of low intraocular pressure, abnormal host corneal shape, and septal defects between the anterior and posterior chamber may cause poor graft adhesion. We report our experience with Descemet stripping automated endothelial keratoplasty (DSAEK) using a nanothin graft in a case of bullous keratopathy (BK) in a lacerated cornea after globe rupture-a situation that encompasses these risk factors.

Case Presentation: An 81-year-old man was admitted to our department after he had ruptured his right eyeball following a fall.

A case of relapsed pan-colonic ulcerative colitis accompanied with gastroduodenal lesions immediately after COVID-19.

Some patients with ulcerative colitis (UC) suffer from complicated UC-associated upper gastrointestinal lesions. However, the trigger of these lesions has not been clarified. Herein, we present a 28-year-old man with relapsed pan-colonic UC accompanied by gastroduodenal lesions immediately after contracting coronavirus disease 2019 (COVID-19).

Revision surgery for malocclusion after open reduction of mandibular fracture: a case report.

Insufficient treatment of mandibular fractures can result in malocclusion, often necessitating revision surgery. Therefore, appropriate surgical treatment by oral and maxillofacial surgeons with adequate consideration of the occlusion is crucial. Moreover, in patients with bone defects between the fractured ends, bone grafting may be required.

Correlation between condylar repositioning, resorption, and mandibular relapse post-orthognathic surgery with the straight locking miniplate technique in patients with Class II and III malocclusion: a retrospective study.

This study investigated the relationship between condylar position, condylar volume, and mandibular relapse following orthognathic surgery in which the proximal segments were temporarily fixed with a positioning device to maintain the condylar position. Computed tomography data (pre-surgery, immediately post-surgery, and 1 year post-surgery) from 12 patients with Class II malocclusion and 20 with Class III were analysed. Condylar volume was significantly lower in Class II patients than in Class III patients at all time-points (P < 0.
