Splenic pseudoaneurysm rupture is a serious condition that sometimes leads to death. Pseudoaneurysm rupture is often treated with transcatheter arterial embolization (TAE), after which the re-rupture rate is 18%–37%. A 59-year-old man presented with back pain, and contrast-enhanced computed tomography (CECT) revealed pancreatic tail cancer with multiple liver metastases. After three courses of chemotherapy, CECT revealed good response with shrinkage of the tumors. However, the patient had back pain and CECT revealed pancreatic pseudocyst with pseudoaneurysm rupture. He underwent angiography, wherein the splenic artery pseudoaneurysm was embolized using TAE. Subsequently, pseudocyst drainage was performed using lumen-apposing metal stent (LAMS) to prevent pseudoaneurysm re-rupture. Thereafter, the pseudocyst shrieked with decreased serum levels of C-reactive protein, allowing the patient to re-institute chemotherapy. Pseudocyst drainage using LAMS was safe and effective when the pancreatic pseudoaneurysm had a high-risk rebleeding due to exposure to pancreatic juice.

Background/Aims: Serum leucine-rich alpha-2 glycoprotein (LRG) is a potential biomarker of Crohn’s disease (CD). This study aimed to evaluate the usefulness of LRG in predicting clinical relapse in patients in remission with CD. Methods: This retrospective observational study assessed the relationships among patient-reported outcome (PRO2), LRG, and other blood markers. The influence of LRG on clinical relapse was assessed in patients in remission with CD. Results: Data of 94 patients tested for LRG between January 2021 and May 2023 were collected. LRG level did not correlate with PRO2 score (ρ = 0.06); however, it strongly correlated with C-reactive protein (CRP) level (r=0.79) and serum albumin level (r=–0.70). Among 69 patients in clinical remission, relapse occurred in 22 patients (31.9%). In the context of predicting relapse, LRG showed the highest area under the curve, followed by CRP level, platelet count, and albumin level. Multivariate analysis revealed that only LRG (P= 0.02) was an independent factor for predicting clinical remission. The cumulative non-relapse rate was significantly higher in patients with LRG < 13.8 μg/mL than in patients in remission with LRG ≥ 13.8 μg/mL and normal CRP level (P= 0.002) or normal albumin level (P= 0.001). Cumulative non-relapse rate was also higher in patients with LRG < 13.8 μg/mL compared to those with LRG ≥ 13.8 μg/mL in patients with L3 or B2+B3 of Montreal calcification. Conclusions LRG is useful in predicting clinical relapse in patients with CD during biological remission. LRG is a useful biomarker for predicting prognosis, even in patients with intestinal stenosis, or previous/present fistulas.

A 73-year-old woman was diagnosed with coronary artery aneurysms associated with coronary-pulmonary arterial fistula in a preoperative examination for transverse colon cancer. One of the aneurysms (28 mm) originated from a branch of the right coronary artery and the other two (16 and 12 mm) originated from a branch of the left coronary artery. We performed surgery to prevent their rupture because the right coronary artery aneurysm showed a tendency to enlarge. Surgery was performed through a median sternotomy under cardiopulmonary bypass. Suture closure of the inflow and outflow of the aneurysm was performed. The coronary-pulmonary arterial fistula was ligated. In addition, suture closure of the outflow of the coronary-pulmonary artery fistula into the pulmonary artery was performed, under direct view after incision of the pulmonary trunk. No residual shunt blood flow in the coronary-pulmonary arterial fistula was observed on postoperative echocardiography. Furthermore, no coronary aneurysm and coronary-pulmonary arterial fistula was recognized on postoperative coronary computed tomography. The patient made an uneventful recovery and was discharged from the hospital on postoperative day 12.

In the 2022 Model Core Curriculum for Medical Education in Japan, "Chapter 3, Educational strategies and assessment" section II. "Learner Assessment," consists of three parts : II-1. Approaches to learner assessment, II-2. Assessment methods, and II-3. Questions about learner assessment. Based on the idea that "the way assessment is done varies from institution to institution," the answer to the "Question" is deliberately not included. We hope that readers will refer to this chapter when planning learning assessments in curriculum development while considering the curriculum's background and context.

At the 71st Annual Meeting of the Japan Society for Oriental Medicine held in August 2021, we conducted a special program, “Pre-graduation and post-graduation Kampo medical education for the next generation,” focusing on Kampo medical education. We summarize and report a mock lecture on standard Kampo medicine conducted jointly with the Japan Council for Kampo Medical Education (JCKME) for the purpose of faculty development. The lecture contents were based on the “Basic Curriculum for Pre-Graduate Education in Kampo Medicine 2016” established by the JCKME, and the common model slides prepared by the JCKME were used. The lectures were pre-recorded for 240 minutes on the “History of Kampo medicine,” “basic theory of Kampo medicine,” “physical examination of Kampo medicine,” “composition and effects of typical Kampo medicines, effects and side effects of typical herbal medicines,” “usefulness of Kampo and clinical cases that were effective,” and “overview of acupuncture and moxibustion treatment,” and were delivered from seven days before to seven days after the annual meeting. This was the first nationwide educational activity for the general meeting of the society. These lectures were viewed 1,017 times nationwide, by medical students, educators, and members of the society.
