Ionescu-Shiley pericardial xenografts implanted in the mitral position between April 1980 and October 1984 were studied. In some cases the cusp was torn in a relatively early postoperative phase, thus requiring an emergency operation. Functional disorders, such as caused by the calcification of the cusp, advance at a relatively moderate pace, and the prognosis of a second operation in cases with valve dysfunction and a chronic course was favorable. The actuarial probability of freedom from reoperation was 88.5±8.7% at 5 years and 55.7±14.5% at 10 years. The structural deterioration of the pericardial valve increased about 5 years after replacement. This tendency was the same as in other bioprostheses. At 10 years the overall actuarial survival rate was 67.2±12.1%. Freedom at 10 years from thromboembolism was 84.6±9.8%. For cases whose the course is under observation at present, the strategy is to recommend an additional operation as far as possible, while continuously observing the function of the valve.

Objective: In Japan, the healthcare authority encourages physicians to prescribe generic drugs in order to reduce the copayments by the patients for pharmaceutical expenses and to improve the financial status of the national medical insurance system.  In accordance with this governmental policy, we have been actively involved in switching original to generic formulations.  Thus, Utemerine® 50 mg injection was replaced with Ritodrine hydrochloride 50 mg intravenous injection produced by Nichiiko.  There have been some reports on adverse events caused by the generic formulations of Ritodrine hydrochloride.  Factors contributing to these adverse effects may include different additives and/or vehicles and the exemption of demonstrating some conditions for approval, including clinical trials.  Therefore, in order to assess the efficacy and safety of a generic formulation of Ritodrine hydrochloride injection formulation compared with the original formulation and to decide on its continued use, we carried out a retrospective cohort study.
Methods: We carried out a retrospective cohort study in order to assess the efficacy and safety of a generic formulation of Ritodrine hydrochloride injection formulation compared with the original formulation.
Results: There were no significant differences in the length of hospital stay, rate of emergency transport to other institutions, gestational week of delivery, rate of stillbirth, rate of abortion, or incidence of adverse events between the two formulations.
Conclusion: Our results may contribute to the safe and secure use of the generic formulations of Ritodrine hydrochloride in the current situation of the increasing use of generic drugs in health care.  Although there are some limitations in our study, the results suggest that there are no particular problems with the continued use of Ritodrine hydrochloride 50 mg intravenous injection produced by Nichiiko.

Otsujito is a well-known Kampo medicine for treatment of hemorrhoidal diseases. In the current report, we present end results for a case of enterocutaneous fistula treated with Kampo medicine in accordance with traditional “sho” indications.
An 81 year-old female developed abdominal wall-intestinal fistula right immediately following partial colectomy due to ischemic sigmoid colic perforation 12 years previously. Two years later, she had a fistulectomy and repair using intraperitoneal mesh for abdominal recruitment. Eight years after repair of the enterocutaneous fistula, she had peritonitis caused by the tardive intraperitoneal mesh infection. Since then, she has had frequent repeated ileus and received conservative treatment for two years. Several local operations and abdominal drainages were performed after transfer to Aizu Medical Center. Kigikenchuto was provided for wound healing for approximately 1 year, and one fistula was finally identified. Otsujito dramatically decreased the leakage of intestinal juice and closed her enterocutaneous fistula.
Angelicae Radix as an anti-inflammatory agent, and Cimicifugae Rhizoma as originally indicated, may have played pivotal roles in this case with Otsujito.

Objective: To clarify how and when Japanese family physicians assess families in their daily practice.Methods: Participants were Japanese family physicians with over one year of experience of full-time work in their clinics, and who were able to join the focus group discussions (FGD) and member checking. The study employed a qualitative research design with semi-structured FGD. Two analysts examined video recordings of the FGD, and the results were verified through member checking and the checking by external members.Results: Physicians assessed families naturally while examining patients for common cold, during vaccination, and during registration in the Japanese care insurance system.Additionally, the physicians assessed the families when they observed or suspected something strange regarding the patient and/or the family.Families were assessed based on how they spent their time during special Japanese events that the family members attended together (e.g., Bon festival or Japanese style New Year holidays), the patient's illness behavior in non-reserved outpatient clinics, and their communication patterns. Furthermore, the family photograph technique for family therapy was also used for assessment.Conclusion: Participants utilized skills of family therapy such as communication patterns and family photographs. They also employed unique skills such as assessment of the families' sharing time during traditional events, assessment of the patient's illness behavior, and general assessments regarding the Japanese care insurance system.

Case 1 : A 56-year-old woman had been suffering from insomnia for 10 years, and multiple joint pains on her shoulders, wrists and fingers for 2 years. She complained of headache, dizziness, heart palpitations, and irritable bowel syndromes. Case 2 : A 72-year-old woman presented with cold and painful feeling in her legs that she had had for 10 years, as well as insomnia, excessive sweating, alopecia and pollakiuria that she had had for two years. In both cases, organic diseases of the joints or muscles were ruled out by several doctors, and the patients had been suffering from malaise and insomnia for which they had been taking brotizolam for several years. Consequently, the patients consulted our department of traditional Japanese medicine (Kampo). Medical interviews revealed that they had been under a lot of stress for a long time because of family problems. Sansoninto (roasted Zizyphi spinosa semen 15 g, Poria 3 g, Cnidii Rhizoma 3 g, Anemarrhenae Rhizoma 3 g,Glycyrrhizae Radix 1.5 g) was prescribed, which reduced the pain in their joints and muscles, and their other complaints, in several weeks. Sansoninto seemed not to alleviate insomnia as effectively as it did the pain and other multi complaints, because the patients were not able to discontinue brotizolam. Patients with multiple complaints including insomnia with fatigue induced by long-term stressful lifestyle may sometimes possibly express non-organic joint or muscle pain. Sansoninto may be an effective prescription for non-organic joint and muscle pain.

At Tokyo Women's Medical University, our curriculum for first-year students is designed to teach the dynamics and etiquette of human relations. During the third year, medical students are expected to anticipate and plan effective therapeutic communication and interaction with patients. A discussion group of 6 students and a member of the human-relations committee first clarify the purpose and develop the training; students then independently participate in human-relations training during the summer vacation. After training, experiences are discussed during class. Although this curriculum has been used for some 10 years, its benefits have been assumed but not validated. We used student reports and questionnaires to examine the effects of this curriculum. The results clearly show that planning and training give the students an opportunity to learn how to establish an effective physician-patient relationship.

Renal damage caused by hemolysis during cardiopulmonary bypass (CPB) was investigated, and the preventive effects of haptoglobin in regard to this condition was also evaluated. Nineteen patients who underwent open heart surgery were divided into two groups: a control group (n=11) and a haptoglobin group (n=8). In the control group, the level of plasma-free hemoglobin increased significantly after CPB (p<0.01), and this level was strongly correlated with renal tubular leaking enzymes: NAG (r=0.76) and γ-GTP (r=0.81), in the Intensive Care Unit or on the first day after surgery. On the contrary, in the haptoglobin group, in which 4, 000 units of haptoglobin was added in the priming solution of CPB, no increased level of plasma free hemoglobin was observed. Furthermore, leak age of renal tubular enzymes were statistically less (p<0.05). It was concluded that free hemoglobin was a cause of renal damage during CPB and the damage was preventable by the administration of haptoglobin.

BACKGROUND: In this study, we examined the influence of exercise loading characteristics on bone metabolic responses and bone morphology in the growth phase and adulthood. METHODS: Running exercise (RUN) and jumping exercise (JUM) were used for the exercise loading in 28-day-old male Wistar rats. Bone metabolism was measured by blood osteocalcin (OC) and tartrate-resistant acid phosphatase (TRACP) levels. For bone morphology, the maximum bone length, bone weight, and bone strength of the femur and tibia were measured. RESULTS: A pre- and post-exercise loading comparison in the growth phase showed significantly increased OC levels in the RUN and JUM groups and significantly decreased TRACP levels in the JUM group. On the other hand, a pre- and post-exercise loading comparison in adulthood showed significantly decreased TRACP levels in the RUN and JUM groups. Femur lengths were significantly shorter in the RUN and JUM groups than in the control (CON) group, while bone weight was significantly greater in the JUM group than in the CON group. CONCLUSIONS: Exercise loading activates OC levels in the growth phase and suppresses TRACP levels in adulthood. On the other hand, these results suggest that excessive exercise loading may suppress bone length.

We performed coronary artery bypass operation on 258 patients from July 1974 to February 1993, of whom 10 underwent a total of 11 reoperations. These 10 patients were not significantly different from the other patients with respect to gender, coronary risk factors and number of grafts used in the first operation, aside from older age and lower LVEF. The interval between the two operations was <1 year (early) or about 10 years (late) in most instances. The most common reasons for reoperation were graft failure from technical problems in early and time-related alterations in graft and progression of original disease in late cases. The outcome of reoperation was less than satisfactory, with 2 operative deaths, IABP required in 5, reoperation for bleeding needed in 3 and severe sternal wound infection of the patent vein graft postoperatively, of which atheromatous debris released from the atherosclerotic vein graft was strongly suspected to be the cause. The old vein graft should be immediately ligated at the beginning of CPB in cases with diffuse atherosclerotic vein graft in which more than several years have passed since initial operation. In reoperation, arterial graft is preferable, especially GEA graft can be used advantageously even with a left thoracotomy approach. Bypass reoperation for occlusion of LAD or Cx should be performed by a left thoracotomy approach.

Background/Aims: Endoscopic biliary drainage is the gold standard treatment for cholangitis. The two methods of biliary drainage are endoscopic biliary stenting and nasobiliary drainage. A novel integrated outside biliary stent and nasobiliary drainage catheter system (UMIDAS NB stent; Olympus Medical Systems) was recently developed. In this study, we evaluated the efficacy of this stent in the treatment of cholangitis caused by common bile duct stones or distal bile duct strictures. Methods: We conducted a retrospective pilot study by examining the medical records of patients who required endoscopic biliary drainage for cholangitis due to common bile duct stones or distal bile duct strictures, and who were treated with a UMIDAS NB stent, between December 2021 and July 2022. Results: Records of 54 consecutive patients were reviewed. Technical and clinical success rates were 47/54 (87.0%) and 52/54 (96.3%), respectively. Adverse events were observed in 12 patients, with six patients experiencing pancreatitis as an adverse event, following endoscopic retrograde cholangiopancreatography (ERCP). Regarding late adverse events, five cases of biliary stent migration into the bile duct were observed. Disease-related death occurred in one patient. Conclusions The outside-type UMIDAS NB stent is an efficacious new method for biliary drainage and can be applied to many indications.
