Examination of endoscopic intracanal observation with an ultrafine-diameter scope.

Objectives: The endoscopic channel can be damaged by instruments during use and cleaning, leading to contamination, infection, and increased repair costs. However, few devices are available to observe the inside of the endoscopic channel. This study employed an ultrafine-diameter scope to examine damage in the endoscopic channel.

Development and validation of the Japanese version of the Public Attitudes Toward Epilepsy (PATE-J) Scale.

Aim: This study aimed to develop and validate a Japanese version of the Public Attitudes Toward Epilepsy (PATE-J) Scale to measure attitudes towards epilepsy among the general Japanese population.

Methods: The study employed a cross-sectional design using an online survey of 537 participants from the general public in Japan, with follow-up surveys at 2 weeks and 3 months. The PATE Scale was translated following standard guidelines and validated by conducting confirmatory factor analysis (CFA) on the complete data set to assess the original two-factor structure of the PATE Scale.

Usefulness of a long hood for the detection of bleeding sites in colonic diverticular hemorrhage: A randomized controlled trial.

Background And Aim: The use of a hood at the tip of a colonoscope enables aspiration, inversion of the diverticulum, and observation of the inside of the diverticulum. In most previous studies, a short hood was used; however, observation of the diverticulum is often inadequate. Long food is promising by previous research, but it was a retrospective study using propensity matching and has some limitations.

Do maxillary dentures protect the skull base from penetration injury?

Key Clinical Message: Foreign bodies penetrating from the oral cavity can damage surrounding tissues. This case is considered an extremely rare and fortunate instance in which a maxillary denture appeared to weaken the external force and change the direction of the scissors, preventing damage to vital organs.

Abstract: The patient was a 73-year-old man.

Clinical outcomes of personalized blastocyst embryo transfer after endometrial receptivity analysis: A multicenter, retrospective cohort study.

Purpose: To evaluate clinical outcomes after endometrial receptivity analysis (ERA).

Methods: This was a multicenter, retrospective cohort study involving 861 women who underwent ERA testing at certified fertility clinics in Japan, and who received subsequent personalized blastocyst embryo transfers (ET) between 2018 and 2020. Clinical outcomes, including pregnancies, miscarriages, and live births, were evaluated according to receptivity status for ERA.

Impact of COVID-19 pandemic on assisted reproductive technology treatment under voluntary lockdown in Japan.

To investigate the impact of a state of emergency (i.e., voluntary lockdown) during the COVID-19 epidemic, we conducted a retrospective cohort study using the Japanese nationwide registry.

Endovascular coils mimicking accidental ingestion of a dental-related foreign body in radiographic imaging.

If a foreign body is seen on chest or abdominal radiographs, accidental aspiration or ingestion of a dental-related foreign body may be suspected. This report describes a case in which vascular embolization coils seen on radiography were suspected to represent a swallowed dental prosthesis. A 72-year-old man with a history of endovascular embolization of portosystemic shunt was admitted for mandibular fracture.

Intussusception associated with pneumatosis cystoides intestinalis in a male adolescent: A case report.

Pneumatosis cystoides intestinalis is an uncommon disease that rarely causes intussusception. We report the case of a 16-year-old male patient with intermittent abdominal pain who was diagnosed with intussusception. The patient had no history of raw food ingestion, fever, diarrhea, or hematochezia.

Prophylactic effect of negative-pressure wound therapy and delayed sutures against incisional-surgical site infection after emergency laparotomy for colorectal perforation: A multicenter retrospective cohort study.

Aim: The prophylactic effect of negative-pressure wound therapy against incisional surgical site infection after highly contaminated laparotomies has not been sufficiently explored. This study aimed to evaluate the prophylactic effect of negative-pressure wound therapy against incisional surgical site infection after emergency surgery for colorectal perforation.

Methods: This nationwide, multicenter, retrospective cohort study analyzed data from the 48 emergency hospitals certificated by the Japanese Society for Abdominal Emergency Medicine.

AdvanCE, a capsule endoscope delivery device, is effective in investigating a waterfall stomach.

AdvanCE is a useful device in patients who cannot swallow capsule endoscopes, or when these remain in the patient's stomach without passing into the duodenum. A net or snare may be used to guide the capsule endoscope into the duodenum when the capsule endoscope becomes stuck in the stomach, but it may be difficult to guide the capsule into the duodenum in some cases, particularly in those of waterfall stomach. In such cases, AdvanCE is found to be an effective guidance tool.

Study Protocol of Cardiac Rehabilitation for Acute Myocardial Infarction From the JROAD/JROAD-DPC Database - JROAD-CR.

Although cardiac rehabilitation (CR) has been reported to be effective for improving the prognosis of acute myocardial infarction (AMI), more patients must participate in CR during admission and as outpatients. Factors contributing to, and countermeasures against, the low CR participation rate need to be identified. Here we describe the protocol for a study designed to evaluate the effectiveness and problems of CR for AMI from the Japanese Registry of All Cardiac and Vascular Diseases (JROAD) and the JROAD-Japanese Diagnosis Procedure Combination system (JROAD-DPC) database.

Assisted reproductive technology in Japan: A summary report for 2020 by the ethics Committee of the Japan Society of obstetrics and gynecology.

Purpose: Since 1986, the Japan Society of Obstetrics and Gynecology assisted reproductive technology (ART) registry system has collected data on national ART use and outcomes trends in Japan. Herein, we describe the characteristics and outcomes of ART cycles registered during 2020 and compare the results with those from 2019.

Methods And Results: In 2020, 621 ART facilities participated in the registration.

Real opinions on general medicine residency programs in Japan: Perspectives from medical students, residents, and young academic generalists.

Medical students and junior residents have five concerns about general medicine training, and senior residents and young academic generalists respond to these concerns. We hope that this paper will help to dispel some common concerns for those who wish to become specialists in general medicine.

Efficacy of Early Cardiac Rehabilitation After Cardiac Surgery - Verification Using Japanese Diagnosis Procedure Combination Data.

The current status of cardiac rehabilitation (CR) after cardiac surgery and the introduction of early CR (E-CR) in Japan are not fully understood. In this study, the current status of E-CR and its efficacy were investigated by the Academic Committee of the Japanese Association of Cardiac Rehabilitation. We examined the rate of introduction of E-CR and its effects among 220,122 patients who underwent major cardiac and thoracic vascular surgery, as registered in the Diagnosis Procedure Combination (DPC) classification system, between April 2012 and March 2018.

Current clinical practice for familial adenomatous polyposis in Japan: A nationwide multicenter study.

Introduction: In Japanese patients with familial adenomatous polyposis (FAP), colectomy tends to be postponed or avoided.

Aim: This study aimed to clarify the current clinical practice from a Japanese multicenter cohort study database.

Methods: We analyzed the records of 250 patients with non-dense FAP who did not require colorectal cancer removal.

Early versus delayed interventions for necrotizing pancreatitis: A systematic review and meta-analysis.

Objectives: Interventions for necrotizing pancreatitis are generally postponed until 4 weeks after the onset of acute pancreatitis, but there remains controversy about whether we should always wait >4 weeks or can intervene early when necessary. This meta-analysis was conducted to evaluate treatment outcomes of necrotizing pancreatitis according to the cut-off defined in the revised Atlanta classification (≤4 vs. >4 weeks).
