Bacterial endocarditis caused by contact lens usage.

A 17-year-old female was transferred to our hospital due to high fever, general fatigue, and dim eyesight. Three weeks before, she had used cosmetic colored contact lenses and then suffered from bloodshot eyes associated with dim eyesight. Intermittent fever and general fatigue were followed by eye symptoms.

A case of situs inversus totalis with hemosuccus pancreaticus due to intrapancreatic pseudocyst perforation of the common hepatic artery treated with a vascular stent graft.

Hemosuccus pancreaticus (HP) is characterized by gastrointestinal bleeding from the papilla of Vater via the pancreatic duct. In this report, we describe a case of HP due to arterial perforation in a pancreatic pseudocyst and discuss the computed tomography (CT) findings and efficacy of stent graft placement. A 64-year-old man with a history of heavy alcohol use, situs inversus totalis, and total gastrectomy was hospitalized with hematochezia.

Case Study of a Refractory Idiopathic Peptic Ulcer in Which 24-h Intragastric pH Monitoring Contributed to Its Pathophysiological Analysis.

Introduction: In recent years, the frequency of idiopathic peptic ulcers (IPUs) has increased. However, the clinicopathological characteristics of IPU have not been fully elucidated and treatment methods for recurrent and refractory cases have not yet been established.

Case Presentation: A man in his forties complained of epigastric discomfort.

Intraoperative Telestration System in Endoscopic Transsphenoidal Surgery Contributes to Improved Surgical Safety and Efficient Surgical Education.

Objective: To evaluate the effectiveness of a "telestration" system in which the mentor annotates the view of the surgical field, for endoscopic transsphenoidal surgery (ETS).

Methods: The use of telestration was evaluated for sellar floor-opening during ETS and for a task performed using ETS simulation training. During ETS, the mentor outlined the opening area of the sella turcica on the monitor and then the trainee surgeon opened the sella, either with the telestration displayed (telestration (+) group, n = 8) or without (telestration (-) group, n = 7).

Development of an Artificial Intelligence Diagnostic System Using Linked Color Imaging for Barrett's Esophagus.

Barrett's esophagus and esophageal adenocarcinoma cases are increasing as gastroesophageal reflux disease increases. Using artificial intelligence (AI) and linked color imaging (LCI), our aim was to establish a method of diagnosis for short-segment Barrett's esophagus (SSBE). We retrospectively selected 624 consecutive patients in total at our hospital, treated between May 2017 and March 2020, who experienced an esophagogastroduodenoscopy with white light imaging (WLI) and LCI.
