Vertebral fractures occur with only slight trauma in patients with diffuse idiopathic skeletal hyperostosis (DISH). However, a lumbar vertebra fracture, due to an intraoperative body position has not been previously reported. An 87-year-old woman with kyphosis sustained a left trochanteric fracture of her femur. The patient was placed in a supine position during the operation. Postoperatively, the patient experienced severe right thigh pain. Magnetic resonance imaging revealed an L4 vertebral fracture. Computed tomography revealed ankylosis from the upper thoracic spine to the sacrum. While in a supine position under general anesthesia, the contact of the patient's lower back with operating table likely created a fulcrum at her lumbosacral spine acting as a long lever arm, bearing the mass of her upper body. We performed L1-S2 posterior stabilization. DISH patients with kyphosis placed in a supine position have an increased risk for lumbar vertebral fracture.

Background/Aims: The necessity for pharyngeal anesthesia during upper gastrointestinal endoscopy is controversial. This study aimed to compare the observation ability with and without pharyngeal anesthesia under midazolam sedation. Methods: This prospective, single-blinded, randomized study included 500 patients who underwent transoral upper gastrointestinal endoscopy under intravenous midazolam sedation. Patients were randomly allocated to pharyngeal anesthesia: PA+ or PA– groups (250 patients/group). The endoscopists obtained 10 images of the oropharynx and hypopharynx. The primary outcome was the non-inferiority of the PA– group in terms of the pharyngeal observation success rate. Results: The pharyngeal observation success rates in the pharyngeal anesthesia with and without (PA+ and PA–) groups were 84.0% and 72.0%, respectively. The PA– group was inferior (p=0.707, non-inferiority) to the PA+ group in terms of observable parts (8.33 vs. 8.86, p=0.006), time (67.2 vs. 58.2 seconds, p=0.001), and pain (1.21±2.37 vs. 0.68±1.78, p=0.004, 0–10 point visual analog scale). Suitable quality images of the posterior wall of the oropharynx, vocal fold, and pyriform sinus were inferior in the PA– group. Subgroup analysis showed a higher sedation level (Ramsay score ≥5) with almost no differences in the pharyngeal observation success rate between the groups. Conclusions Non-pharyngeal anesthesia showed no non-inferiority in pharyngeal observation ability. Pharyngeal anesthesia may improve pharyngeal observation ability in the hypopharynx and reduce pain. However, deeper anesthesia may reduce this difference.

We report an extremely rare case of primary squamous cell carcinoma of the stomach. A 69-year-old man was admitted to our hospital with a 2-month history of dysphagia and tarry stools. Endoscopic examination revealed a cauliflower-shaped protruding mass along the lesser curvature of the gastric cardia. Biopsy of the lesion revealed squamous cell carcinoma of the stomach. Computed tomography revealed a thickened stomach wall and a mass protruding into the gastric lumen. Total gastrectomy with splenectomy, distal pancreatectomy, and Roux-en-Y reconstruction was performed, together with a lower thoracic esophagectomy via a left thoracotomy. Histopathological examination of the specimen revealed well-differentiated squamous cell carcinoma of the stomach. Postoperative follow-up was uneventful for the first 18 months. However, multiple liver metastases and para-aortic lymph node metastasis developed subsequently. Despite systemic combination chemotherapy, the patient died because of progression of the recurrent tumors. Here, we review the characteristics of 56 cases of gastric squamous cell carcinoma reported in Japan.

We investigated the efficacy of choreitogoshimotsuto for radiation hemorrhagic cystitis. Of the 11 patients who could be followed up, hematuria disappeared in 8 cases. The median time to disappearance of gross hematuria was 74 days. There was no recurrence. Of the 3 ineffective patients, one had urinary diversion, and two had transurethral electrocoagulation and hyperbaric oxygen therapy. There were no adverse events associated with the use of choreitogoshimotsuto. Choreitogoshimotsuto might be effective for radiation hemorrhagic cystitis.

While there is an emphasis on fostering the next generation of medical educators, it is difficult for the younger generation to find opportunities to deepen their knowledge of medical education regularly amid their busy clinical work. Using journal clubs is a strategy for lifelong learning in the professional field; yet, it is difficult to operate and maintain one. We established an online journal club for medical education and research with 9- to 12-year post-graduates from different institutions across Japan. While it is generally said that even face-to-face journal clubs are difficult to sustain, we were able to hold more than 40 online meetings in one year. We discussed why our approach was feasible, citing social congruence theory and self-determination theory.

Residents have teaching roles in clinical practice, and the importance of these roles has been pointed out. This is due to their proximity to learners as Near-Peers. There are two aspects to consider: cognitive proximity, which allows them to share what learners don’t know, and spatial proximity, which allows us to share time and space for an extended period. Residents-as-teachers programs, which aim to improve teaching skills for residents, are being developed all over the world, but are still rare in Japan. We are conducting research to determine what teaching competencies residents should have. We are running a one-year fellowship based on the results of that research. The scale of the program has gradually increased, and in 2020, due to COVID-19, the fellowship went online. We restructured the fellowship in terms of Study/Workload, Enhancing Engagement, and Technical Issues. We received high satisfaction ratings for the online implementation.
