Since November 1999 we have attempted to use a right heart bypass (RHB) system for beating heart coronary artery bypass grafting (CABG), which system produce better exposure of lateral and posterior wall of the heart and so enable us to facilitate bypass grafting to these branches. We report on our initial clinical experience with this system and the purpose of this study is to evaluate the efficacy of this system. To clarify the efficacy of the RHB system, we compared the intraoperative and postoperative clinical course, as well as outcome, between patients who underwent beating heart CABG with RHB and patients without RHB. Seventy-seven patients underwent beating heart CABG with RHB (RHB group) between November 1999 and December 2001. In the same period, 88 patients underwent beating heart CABG without RHB. Of these latter, 30 patients needed displacement of the beating heart in order to expose target coronary arteries (OPCAB group). Perioperative clinical parameters were compared between the groups. Patients in the RHB group received more grafts (2.4±0.6) than patients in the OPCAB group (2.0±0.2, p=0.002). There were no hospital deaths in either group. While displacing the beating heart, SvO₂ decreased and pulmonary artery pressure increased in both groups. Nevertheless, the value of SvO₂ was significantly higher in RHB group while displacing to expose the circumflex region (p=0.048) and the distal right coronary artery region (p<0.01). The effect of elevation of pulmonary artery pressure in the RHB group was lower than that in the OPCAB group, but it was not statistically different. Water balance during operation was 2, 898±1, 019ml in the RHB group and the 2, 237±807ml in OPCAB group (p=0.002). Body temperature following operation was 36.0±0.8°C in the RHB group and 36.5±0.8°C in the OPCAB group (p<0.01). However, no differences were found in postoperative blood loss, required transfusion, duration of mechanical ventilation, ICU stay and hospital stay. No patient had postoperative complications related to the RHB system. The introduction of the RHB enabled bypass grafting to posterior wall vessels with better exposure and under greater hemodynamic stability. Therefore we think it a very effective support system which enable multiple coronary revascularization on beating heart CABG.

Objective: The Hyogo Hospital Pharmaceutical Society has been conducting an original pharmacy postgraduate education program, “lifelong learning program (to nurture pharmacy specialists)”, since 2002 using the Internet.  To understand the status of using this program, this study employed a questionnaire survey involving all registered members.
Methods: Subjects were all members (1,870) of the society.  Questionnaires were distributed and collected by mail.
Results: Only 20.1% of the members had experience of using the program, and the frequency of using it was less than once per 6-12 months in 60% of the members.  Their level of awareness concerning the acquisition of credits for lifelong learning was 36.9%.  The program category they wished to take was an infection-related program in 26.1% of the members, which was the highest.
Conclusion: As reasons for only a small number of members using the program, the following are considered: loss of user’s ID and password required to login, and lack of awareness concerning the acquisition of credits for lifelong learning offered by the Japanese Society of Hospital Pharmacists.  As future issues, we must encourage members to obtain a new password and be proactively involved in preparing new program categories that the members wish to take, in order to promote the continuous use of the program.

Between January 1986 and August 1989, four patients, whose urinary tuberculous cultures were positive, were treated in our hospital. They represented 0.66% of the total number of the new patiants who visited the outpatient department during this period. Also during the same period, two other patiants with unilateral old renal tuberculosis underwent nephrectomy.
Since the middle of this century, the development of chemotherapy has decreased the number of the patiants with urinary tuberculosis. However, there has been little decrease in recent several years, and our report supports this evidence. So, the possibility of urinary tuberculosis cannot be made light of in the urological examination, especially for the patiants with refractory urinary tract infection.

A 71-year-old man who had been on peritoneal dialysis for 6 years was referred to our hospital for renal transplantation from a living donor. Preoperative echocardiography revealed diffuse severe hypokinesis, a left ventricular ejection fraction (LVEF) of 25%, and a pedicled floating mass in the right atrium. He had not exhibited positive symptoms of active endocarditis or metastatic malignant tumor, and the causes of cardiomyopathy seemed to be uremic and/or ischemic factors. Renal transplantation was postponed, and the extirpation of the mass in the right atrium was scheduled. LVEF improved to 48% 2 months following the induction of hemodialysis before the cardiac operation. Pathohistological findings of the extirpated intra-atrial mass showed sphachelus and fibrotic thrombus, which meant asymptomatic healed infective endocarditis. He recovered uneventfully, and underwent a living renal transplantation from living donor 5 months after the cardiac operation. LVEF further improved better to 56%, and his performance status was remarkably improved. These results imply that renal transplantation and hemodialysis in peritoneal dialysis patients with uremic cardiomyopathy can achive improvement of cardiac function and enable a safe cardiac operation.

A 24-year-old woman underwent successful repair of a traumatic pseudoaneurysm of the aortic isthmus concomitant with right diaphragmatic hernia which developed after a traffic accident, and the steering wheel of the crashed car was considered responsible for both lesions. Due to the right diaphragmatic hernia, she could breathe mainly with the left lung only. The aortic isthmus aneurysm was considered to be a pseudoaneurysm, and because of the potential risk of rupture, we performed urgent aortic surgery. Prior to a left thoracotomy, we anastomosed an 8-mm prosthetic graft to the right axillary artery. When the left lung was collapsed in order to perform a femoro-femoral bypass, the SpO₂ level of her right index finger and her cerebral rSO₂ markedly decreased. Therefore, we administered additional perfusion via the right axillary artery, which provided sufficient oxygen to the upper body and brain. The patient underwent Marlex mesh reinforcement of the right diaphragmatic hernia 30 days after grafting, and is doing well 1 year postoperatively.

Little is known about the treatment of gender dysphoria among children and adolescents in Japan. This preliminary survey aims to improve understanding of current clinical practice for treatment of children with gender dysphoria. Subjects were 315 certified child and adolescent psychiatrists in Japan. The questionnaire asked about clinical experiences concerning gender dysphoria and gender identity-related concerns. A total of 128 psychiatrists responded to the questionnaire. Mean length of clinical experience was 24.2±10.0 years in total and 16.9±11.5 years as child and adolescent psychiatry specialists. Among the respondents, 74 (57.8%) had seen children and adolescents with DSM-5 gender dysphoria, and 87 (67.7%) had examined cases with gender identity-related concerns. The mean number of experienced cases with gender dysphoria was 1.80±2.3 per respondent. We found that even among certified child and adolescent psychiatrists in Japan, experience with treatment of children with gender dysphoria was limited.

Introduction: Vaccine policies have changed in recent years in Japan. In the present study, we assessed practices, recommendations, knowledge, and sources of information among primary care physicians (PCPs) regarding vaccinations in Japan. Methods: We conducted a nationwide cross-sectional study targeting PCPs in Japan. We used a web-based self-administered questionnaire targeting physicians that were members of the Japan Primary Care Association in 2019. We analyzed respondent administrations, recommendations, knowledge, and sources of information regarding vaccinations. Results: We received responses from 1,084 PCPs (20.1%) and invited 981 participants for the analysis. The rates at which physicians gave routine and voluntary vaccines in their own practices were 23.3-95.5% and 13.2-94.4%, respectively. The active recommendation rates for routine and voluntary vaccines were 41.6-92.0% and 13.6-75.5%, respectively. Furthermore, among routine vaccines, human papillomavirus vaccine was the least administered and recommended. PCPs working at clinics had the most accurate knowledge about vaccinations, and PCPs utilized academic organizations most readily as an information resource. Conclusion: We clarified practices, recommendations, knowledge, and sources of information regarding vaccinations among PCPs in Japan.

PURPOSE: The purpose of this study was to evaluate the effect of concomitant arthroscopic lateral release (LR) in open wedge high tibial osteotomy (OWHTO) by comparing the pre- and postoperative radiological parameters of patellar position and orientation. MATERIALS AND METHODS: The study was comprised of 19 knees undergoing OWHTO and concomitant LR and 18 knees undergoing OWHTO alone. Radiological parameters for patellar position and orientation included the Caton-Deschamps index (CDI), Blackburne-Peel index (BPI), patellar tilting angle (PTA), patellar lateral shift (PLS), and patellofemoral distance (PFD), which were evaluated in the preoperative period and at one year after surgery. RESULTS: Patellar height was significantly reduced after surgery as indicated by the decrease in BPI (p=0.03) in the OWHTO/LR group, and decrease in CDI (p=0.03) and BPI (p=0.04) in the OWHTO alone group. PTA and PLS were significantly reduced after the combined OWHTO/LR procedure (p=0.04 and p=0.04, respectively). By contrast, no significant changes were detected when isolated OWHTO was performed. CONCLUSIONS: OWHTO induced a postoperative decrease in patellar height in both groups. Regarding the change in patellofemoral alignment, concomitant LR in OWHTO significantly decreased lateral patellar tilt and shift, while no significant difference in those parameters were noted in the OWHTO alone knees.

Purpose: To evaluate the postoperative change in patellar position after medial closed distal femoral osteotomy (DFO) performed for valgus osteoarthritic knees. Methods: The study included 21 consecutive knees in 20 patients undergoing DFO. A minimum of 2-year followup data was obtained for all subjects with a mean follow-up period of 42 months (range 31–59 months). The patellar position was evaluated on plain radiographs preoperatively, 1-year postoperatively, and 2-year postoperatively. For patellar height, the modified Insall–Salvati Index (mISI), modified Caton–Deschamps Index (mCDI) and modified Blackburne–Peel Index (mBPI) were measured on the standing lateral radiographs.Patellofemoral alignment on the axial plane was assessed on skyline views with 30° flexion based on the measurements for lateral patellar tilt (LPT) and lateral patellar shift (LPS). Measured values at pre- and postoperative phases were statistically compared using a two-way analysis of variance. Results: All indices including mISI, mCDI, mBPI, LPT and LPS showed no statistically significant postoperative changes. Conclusion Medial closed-wedge DFO performed for valgus osteoarthritic knees did not significantly influence patellofemoral alignment either on the sagittal or axial plane. Therefore, to highlight the clinical relevance of our findings, medial closed-wedge DFO for the valgus knee does not adversely affect the patellofemoral joint.Level of evidence: Level IV, case series.
