A Case of Refractory Esophageal Ulcer Caused by Radiotherapy for Hepatocellular Carcinoma.

A 77-year-old man who underwent radiotherapy for hepatocellular carcinoma 6 months prior consulted for esophageal obstruction. Esophagogastroduodenoscopy revealed an esophageal ulcer caused by radiotherapy for hepatocellular carcinoma. He was treated with dietary counseling and vonoprazan.

Examination of Endoscopic Ultrasonographic Diagnosis for the Depth of Early Gastric Cancer.

Background: Endoscopic ultrasonography (EUS) is one of the helpful tools to diagnose depth of early gastric cancer (EGC). In this study, we examined efficiencies of EUS for EGC such as overall accuracy, risk factors of over/under-staging, and accuracies of each invasive distance.

Methods: A total of 403 EGC lesions that could be investigated by EUS during pre-operation and histological diagnosis after endoscopic submucosal dissection (ESD) or surgery were enrolled in this study.

Relationship Between Gastroesophageal Reflux Disease and Endoscopic Finding "Iodine-Unstained Streak".

Background: Esophagogastroduodenoscopy (EGD) with iodine stain is a useful and diffused method for diagnosing esophageal cancer. We can perform the procedure easily with endoscopic system which does not comprise image-enhanced endoscopy. Several studies advocated that iodine-unstained streaks are a characteristic finding of gastroesophageal reflux disease (GERD).

Relationship Between Blood Pressure Levels on Admission and the Onset of Acute Pneumonia in Elderly Patients With Cerebral Hemorrhage.

Background: We have reported that hypertension on admission in elderly patients with acute cerebral infarction is an independent predictor for the development of acute pneumonia. However, the relationship between blood pressure on admission owing to cerebral hemorrhage and the development of pneumonia has not been fully investigated. In this study, we evaluated the relationship between blood pressure levels on admission and the development of pneumonia in elderly patients with cerebral hemorrhage who were in the acute phase.
