To improve the prognosis of patients with pancreatic cancer, more accurate serum diagnostic methods are required. We used metabolomics as a method for cancer.Sera from healthy volunteers, and chronic pancreatitis were collected at multiple institutions. The cancer volunteers randomly allocated to training or validation set. All cases included in In each study, subjects' metabolites analyzed by gas chromatography mass spectrometry (GC/MS) data processing system using an in-house library....

We conducted a multicenter, retrospective study to determine the anatomical distribution and prognostic factors of gastrointestinal (GI) follicular lymphoma (FL). This included 125 patients with stage I II(1) GI-FL. Of patients, small intestine was examined in 70 double-balloon endoscopy and/or capsule endoscopy. The most frequently involved GI-FL site duodenal second portion (DSP) (81%), followed by jejunum (40%); 85% involvement DSP also had jejunal or ileal lesions. absence abdominal...

ObjectiveOwing to the risks of serious and sustained toxicity, anticancer drugs such as cisplatin irinotecan cannot be readily administered patients with gastric cancer severe peritoneal metastasis. Therefore, a standard chemotherapy regimen has yet established for these types patients. This randomized study investigated utility sequential methotrexate 5-fluorouracil therapy vs. continuous infusion

Abstract Background Photodynamic therapy (PDT) is a less invasive and effective salvage treatment for local failure after chemoradiotherapy (CRT) esophageal cancer, however it causes high rate of skin phototoxicity requires long sun shade period. Talaporfin sodium rapidly cleared photosensitizer that expected to have phototoxicity. This study was undertaken clarify the optimum laser fluence PDT using talaporfin diode patients with CRT or radiotherapy (RT) cancer. Methods phase I, dose...

Background and study aim Magnifying narrow-band imaging (M-NBI) is useful for the accurate diagnosis of early gastric cancer (EGC). However, acquiring skill at M-NBI takes substantial effort. An Internet-based e-learning system to teach endoscopic EGC using has been developed. This evaluated its effectiveness. Participants methods was designed as a multicenter randomized controlled trial. We recruited endoscopists participants from all over Japan. After completing Test 1, which consisted...

Background . Delayed perforation is a rare but severe complication of endoscopic submucosal dissection (ESD) for early gastric neoplasm (EGN). The aim this study was to clarify clinical factors related delayed after ESD. Methods A total 1158 consecutive patients with 1199 EGNs underwent ESD at our hospital between January 2000 and December 2015. Univariate analysis used identify clinicopathological perforation. Moreover, duration cautery needed hemostasis measured by comparison perforated...

Kounis syndrome is defined as the concurrence of acute coronary syndromes in setting allergic or anaphylactic reactions. It primarily affects men aged 40–70 years and often associated with chest pain. This unrecognized undiagnosed clinical practice due to a low level awareness.

Dengue fever (DF) can be complicated by hemophagocytic lymphohistiocytosis (HLH). Steroid administration is markedly effective for this hematologic complication, and other viral infections. We present a rare case of DF-associated HLH that improved with steroid-sparing supportive care. A 47-year-old Japanese male diabetes mellitus no history DF traveled to the Philippines 10 days before his hospitalization. Three emergency admission, he experienced joint pain was referred our hospital...

COVID-19 can lead to severe pneumonia, requiring mechanical ventilation. While increased sputum secretion could cause airway obstruction during ventilation, there are few reported cases in the literature. We report a case of 65-year-old man with diabetes and pneumonia ventilation treated hydroxychloroquine, azithromycin, nafamostat, prone positioning. Initially, consisted heat moisture exchanger, endotracheal tube aspiration, subglottic drainage using closed suction system. However,...

Introduction: Favorable long-term outcomes of endoscopic submucosal dissection (ESD) for early remnant gastric cancer (ERGC) have been reported in single-center studies from advanced institutions. However, no examined the using a multicenter database. This study aimed to investigate aforementioned approach large Methods: retrospective cohort included 242 cases with 256 lesions that underwent ESD ERGC between April 2009 and March 2019 across 12 centers. We investigated these patients...

The effects of cholecystokinin (CCK) and other pancreatic secretagogues on phosphatidylcholine (PC) synthesis were studied in isolated rat acini. When acini incubated with [3H]choline the presence 1 nM CCK-octapeptide (CCK8) for 60 min, incorporations into both water-soluble choline metabolites PC reduced by CCK8 to 74 41% control, respectively. Pulse-chase study revealed that disappearance phosphocholine PC. Other Ca(2+)-mobilizing such as carbamylcholine, bombesin, Ca2+ ionophore A23187...
