A 69 year old man who was admitted with hoarseness and diagnosed as aneurysm of the diverticulum of the ductus arteriosus was reported. Operation was performed through a median sternotomy under partial cardiopulmonary bypass. Saccular form aneurysm, had a stalk attaching to left pulmonary artery, was repaired using Dacron patch prosthesis. His postoperative course was uneventful except transient left pleural effusion. Because of fragirity of aneurysm in the adult, early surgical intervention is recommended. To our knowledge, this is 11th surgically treated case to be reported in the literature in Japan.

Videotape feedback reportedly improves communication skills in students learning to conduct medical interviews. We carried out a study of videotape feedback in the undergraduate training program of the department of neuropsychiatry. To evaluate the interviews, we used objective structured clinical examinations and feedback from interviewed patients. The students showed several shortcomings, such as passive investigation into symptoms, past history, family history and explanatory models; poorly expressed empathy; unclear summation; poor explanation about what interviewees should do after the interview; and infrequent use of specific probes and silence skills. Feedback from patients was more favorable than that from instructors. Because our program asking psychiatric patients to participate as interviewees seems to have both advantages and disadvantages, using simulated patients would be helpful for examining the validity of our program.

We present a rare case of a 59-year-old-man with a diagnosis of hypertrophic cardiomyopathy (HCM) complicated with left ventricular thrombus. He was admitted to our hospital because of acute re-occlusion of the right brachial artery. Thrombectomy was performed and reperfusion was obtained. Anti-coagulation therapy was started from that day. Four days after surgery, echocardiography revealed mobile thrombus in left ventricular apical aneurysm that was not detected on admission. An emergency thrombectomy and left ventriculoplasty was performed. The patient was discharged 22 days after surgery in good condition.

We report 2 cases of successful proximal reoperations after acute type A dissection. Case 1 : A 53-year-old man underwent ascending aorta and aortic arch replacement and aortic valve re-suspension for acute type A dissection with aortic valve regurgitation in 1992. Thirteen years after the first operation, computed tomography demonstrated a Valsalva aneurysm (74 mm) and Doppler echocardiography showed moderate aortic valve regurgitation. Therefore, we performed an operation. We could not locate the dissection in the Valsalva sinus, and the aortic valve cusps had organic change. A David procedure was performed. The postoperative course was uneventful and he was discharged on the 19th postoperative day. Case 2 : A 65-year-old woman underwent ascending aorta replacement and aortic valve resuspension for acute type A dissection with aortic valve regurgitation in 1997, but 11 years after the first operation, computed tomography demonstrated a Valsalva aneurysm (55 mm) and arch aneurysm (65 mm) with stenosis of the innominate vein and she had facial and left arm edema. Doppler echocardiography showed moderate aortic valve regurgitation. We could not find the location of dissection in the Valsalva sinus or aortic arch, and aortic valve cusps had no organic change. A Bentall procedure and total arch replacement were performed and her postoperative course was uneventful.

STUDY DESIGN: Retrospective case series. PURPOSE: To investigate the oncological outcomes, including distant relapse, after en bloc spondylectomy (EBS) for spinal metastases in patients with a minimum of 2-year follow-up. OVERVIEW OF LITERATURE: Although EBS has been reported to be locally curative and extend survival in select patients with spinal metastases, detailed reports regarding the control of distant relapse after EBS are lacking. METHODS: We conducted a retrospective review of 18 consecutive patients (median age at EBS, 62 years; range, 40–77 years) who underwent EBS for spinal metastases between 1991 and 2015. The primary cancer sites included the kidney (n=7), thyroid (n=4), liver (n=3), and other locations (n=4). Survival rates were estimated using the Kaplan–Meier method, and groups were compared using the log-rank method. RESULTS: The median operative time and intraoperative blood loss were 767.5 minutes and 2,375 g, respectively. Twelve patients (66.7%) experienced perioperative complications. Five patients (27.8%) experienced local recurrence of the tumor at a median of 12.5 months after EBS, four of which had a positive resection margin status. Thirteen patients (72.2%) experienced distant relapse at a median of 21 months after EBS. The estimated median survival period after distant relapse was 20 months (95% confidence interval, 0.71–39.29 months). No association was found between resection margin status and distant relapse. Overall, the 2-year, 5-year, and 10-year survival rates after EBS were 72.2%, 48.8%, and 27.1%, respectively. Importantly, the era in which EBS was performed did not impact the oncological outcomes. CONCLUSIONS: Our results suggest that EBS by itself, even if margin-free, cannot prevent further dissemination, which occurred in >70% of patients at a median of 21 months after EBS. These results should be considered and conveyed to patients for clinical decision-making.

Objective: In 2013, a cohort study aimed to clarify the positive and negative effects of introducing the human papillomavirus (HPV) testing for population-based cervical cancer screening has been launched in Japan. This study included four screenings during the subsequent 7-year follow-up period. We aim to describe the results of the first round of this study on cervical cancer screening here. Methods: This study began in September 2013 with recruitment completed in March 2016.Women aged 30–49 years were divided into 2 groups: those who received uterine cervical cytology alone in the first year (control group), or those who received a combination of cytology and HPV testing (intervention group), based on their age. After first screening, women with positive result of cytology or positive HPV test required referral. We summarized the results of the first round of cervical cancer screening. Results: Of the 25,074 women who were eligible for the study, 13,845 women (55.2%) were screened with cytology alone; 11,229 women (44.8%) received a combination of cytology and HPV testing. After screening, 407 women (2.9%) in the control group and 1,003 women (8.9%) in the intervention group required referral, respectively. Adding HPV testing increased referral rate significantly (p<0.001). Conclusion After first screening, introduction of HPV testing appears to contribute to significantly higher referral rates, suggesting that the number of colposcopies as a detailed examination may increase. These preliminary findings suggest that if HPV testing is introduced into screening, medical institutions need to be prepared for an increasing number of follow-up examinations.

Background/Aims: Pathological evaluation is crucial for diagnosing biliary lesions and determining appropriate treatment strategies. However, tissue sampling via the transpapillary route can be difficult. In this study, we aimed to assess the efficacy and safety of a novel tapered-tip sheath system for tissue sampling from biliary strictures. Methods: This single-center, randomized, parallel-group clinical trial included patients aged 20 to 85 years admitted to Kyoto University Hospital for biliary strictures. The patients were randomly assigned (1:1) to a new or conventional method group. The primary outcome was technical success of biopsy at the target bile duct using the assigned method, as determined in accordance with the intention-to-treat principle. Adverse events were assessed in all eligible patients. Results: Fifty-six patients were assessed for eligibility between September 2020 and March 2023; 50 patients were enrolled. The patients were randomly divided into the new (n=25) method group and the conventional (n=25) method group. Technical success was achieved in 96.0% (24/25) and 48.0% (12/25) of patients in the new and conventional method groups, respectively (risk ratio, 2.00; 95% confidence interval [CI], 1.32 to 3.03; risk difference, 48.0%; 95% CI, 27.0% to 69.0%; p<0.001). Adverse events occurred in 4.0% (1/25) and 36.0% (9/25) of patients in the new and conventional method groups, respectively (risk ratio, 0.11; 95% CI, 0.02 to 0.81; risk difference, –32.0%; 95% CI, –52.3% to –11.7%; p=0.005). Conclusions The novel tapered-tip sheath system is a promising option for precisely and safely delivering biopsy forceps to target sites, thereby facilitating the diagnosis of biliary strictures.
