Article Synopsis
- - This study examined the outcomes of elderly patients (over 65 years) with gastric cancer who received best supportive care, focusing on those diagnosed between 2014 and 2019.
- - Results showed that median survival times varied significantly based on cancer stage, with stage 0 patients surviving an average of 1,987 days compared to only 43 days for stage IV patients.
- - The findings indicated that cancer stage and performance status are important factors impacting both overall and cancer-specific mortality in elderly patients, helping guide treatment decisions in future cases.
Article Synopsis
- - The text discusses a rare case of phlegmonous gastritis found during an autopsy of a patient who had cirrhosis related to nonalcoholic steatohepatitis.
- - The patient experienced severe health decline, including anorexia and liver dysfunction, ultimately leading to death due to hepatic failure within two weeks.
- - The report emphasizes the need for awareness that phlegmonous gastritis can occur as a complication in patients with advanced liver cirrhosis, despite its rare occurrence.
Article Synopsis
- * She was admitted to the hospital due to jaundice and liver dysfunction, leading to diagnosis through various tests and liver histology.
- * This case is notable as it appears to be the first documented instance of autoimmune hepatitis occurring post-COVID-19 vaccination in a patient with a background of Sjögren's syndrome.
Intrahepatic mucinous cholangiocarcinoma (IHMC) is rare and behaves notoriously; however, the details of the clinicopathological characteristics of IHMC remain unknown. A 70-year-old man was admitted for examination of the hepatic mass in the S1 segment. He underwent extended left hepatic lobectomy.

- * He received hepatic arterial infusion chemotherapy (HAIC) and then a combination of sorafenib and HAIC after the tumors progressed.
- * Although the sequential therapy was effective in shrinking the liver tumors, the patient ultimately died of respiratory failure attributed to primary lung cancer, with autopsy findings indicating necrotic tissue and few viable HCC cells left.
We report a rare case of undifferentiated-type intramucosal gastric cancer that occurred in the fornix of the stomach without Helicobacter pylori infection, which consisted mainly of poorly differentiated adenocarcinoma. A 49-year-old man visited our hospital for a follow-up endoscopic examination of a small depressed lesion of the gastric fornix detected by surveillance esophagogastroduodenoscopy. On magnifying endoscopy with blue laser imaging, the depressed lesion (approximately 10 mm in diameter) was regarded as undifferentiated-type early gastric cancer that proved to be a poorly differentiated adenocarcinoma by histological examination of biopsied specimens.

Article Synopsis
- - A patient with liver dysfunction was diagnosed with IgG4-related autoimmune hepatitis (IgG4-AIH) after a liver biopsy revealed IgG4-positive plasma cell infiltration and high serum IgG4 levels.
- - Later imaging studies showed the presence of two inflammatory pseudotumors (IPTs) in the liver, which are also considered IgG4-related diseases, marking a rare concurrent occurrence of both conditions.
- - The patient was treated with steroids for a separate diagnosis of cryptogenic organized pneumonia, leading to improvement in her liver dysfunction and resolution of one of the IPTs.
A 41-year-old woman who had a pancreatic tail tumor and multiple liver tumors was referred to our hospital. The results of abdominal US, CT and MRI, and histopathological and immunohistochemical findings of the liver tumor biopsy revealed a pancreatic neuroendocrine tumor with excessively-advanced liver metastasis. We treated her with S-1/gemcitabine combination chemotherapy plus long-acting somatostatin analogue octreotide, which produced tumor stabilization and good quality of life for 7 months, and survival time of 15 months.
View Article and Find Full Text PDFPurpose: To inform about the impact of a recent movement towards a policy to develop integrative networked electronic health record (EHR) as a basis for cooperation among care teams and with patients and in support of safe patient care in Japan.
Methods: The author headed a commission developing policy for health record (HR) structure and its computerization. It executed two questionnaire surveys as the basis for its work.
Background: Ticlopidine hydrochloride-induced liver abnormalities have been reported in the world. In Japan, the five-year (1995-2000) spontaneous serious reports of ticlopidine finds that liver injury accounts for about half of the reports.
Objective: Clinical characteristics of ticlopidine-induced liver injury were investigated to establish the prevention strategy.
We conducted a drastic change in our hospital information system to support patient participatory health care provided in the New Hiroshima University Hospital (HUH). The new information system in HUH (HU-MIND II-Hiroshima University Hospital Medical Intelligence and Notice Delivery system II) is designed as "clinical management system" (CMS). The core of this CMS is the electronic health record (EHR), which aims to assure both the patients' right to know, and the attendants' accountability.
