In Japan, young generalists work in various clinical settings depending on the needs ; they work as family physicians, geriatricians, and hospitalists/general internists. In this symposium, four young generalists from different backgrounds discussed the future of primary care medicine in Japan. First, they presented their dream of primary care. Secondly, geriatric end-of-life issues were discussed, and the suggestion was made that the obtaining of informed consent at an earlier time in an outpatient setting while including patients' families is important in terms of successful advanced care planning. Finally, the issues of career planning for young generalists were focused on. It was revealed that most young generalists understand the importance of obtaining various work-related experiences to develop their skills, but they find it difficult to set their career plan because of the lack of a support system. A stronger support system provided by the JPCA and enhanced solidarity among young generalists are needed.

From 1976 to 1993, 13 patients with high aortic occlusion were treated surgically. Bypass grafting from infrarenal abdominal aorta to the iliac or femoral arteries was performed in 9 patients, endarterectomy with patch angioplasty in 2, thrombectomy followed by straight graft replacement in 1 and bilateral axillo-femoral artery bypass grafting in 1. In 9 patients, femoro-popliteal run-off was determined by arteriography before or during operation. Occlusion of the femoral artery was detected in two patients, and femoro-popliteal bypass grafting was simultaneously performed with aortic revascularization. Two patients died in the early postoperative period (1: fulminant hepatitis, 1: cerebral infarction), and 4 patients died in the late postoperative period (2: ischemic heart disease, 1: cerebral bleeding, 1: malignant tumor). In one patient the iliac artery occluded 13 years after endarterectomy. All other patients showed patent grafts and satisfactory conditions. In cases of high aortic occlusion, late postoperative results were satisfactory after anatomical revascularization. Ischemic heart disease and cerebral vascular accident were important concerning late complications. Postoperative careful follow-up is necessary.

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.

Five patients with vascular graft infections were surgically treated over a 16-year period. Primary diseases were arteriosclerosis obliterans in 3 cases and invasion of malignant diseases in 2 cases. The most common site of infection was the groin (3 of 5). Staphylococcus aureus was the most common pathogen. Administration of antibiotics, drainage and lavage with povidone iodine solution were performed in 4 patients (40-64 days). All patients underwent graft resection and reconstruction. Infected parts of the previous grafts were removed. Total removal of the previous graft was performed in 2 cases and partial removal was performed in 3 cases. To avoid re-infection, long extra-anatomical bypass was performed in 4 cases. The post operative courses of the five patients were uneventful.

BACKGROUND/AIMS: Recent genome-wide analyses have provided strong evidence concerning adverse events caused by thiopurine drugs such as azathioprine (AZA) and 6-mercaptopurine. The strong associations identified between NUDT15 p.Arg139Cys and thiopurine-induced leukopenia and severe hair loss have been studied and confirmed over the last 2 years. However, other coding variants, including NUDT15 p.Val18_Val19insGlyVal, NUDT15 p.Val18Ile, and FTO p.Ala134Thr, and a noncoding variation in RUNX1 (rs2834826) remain to be examined in detail in this respect. Therefore, we investigated the correlation between these adverse events and the 5 recently identified variants mentioned above among Japanese patients with inflammatory bowel diseases (IBD). METHODS: One hundred sixty thiopurine-treated patients with IBD were enrolled. Genotyping was performed using TaqMan SNP Genotyping Assays or Sanger sequencing. RESULTS: None of the 5 variants were associated with gastrointestinal intolerance to AZA. However, NUDT15 p.Arg139Cys was significantly associated with the interval between initiation and discontinuation of AZA among patients with gastrointestinal intolerance. This variant was strongly associated with early (<8 weeks) and late (≥8 weeks) leukopenia and severe hair loss. Moreover, it correlated with the interval between initiation of thiopurine therapy and leukopenia occurrence, and average thiopurine dose. NUDT15 p.Val18_Val19insGlyVal, NUDT15 p.Val18Ile, FTO p.Ala134Thr, and RUNX1 rs2834826 exhibited no significant relationship with the adverse events examined. CONCLUSIONS: Of the 5 variants investigated, NUDT15 p.Arg139Cys had the strongest impact on thiopurine-induced leukopenia and severe hair loss; therefore, its genotyping should be prioritized over that of other variants in efforts to predict these adverse events in Japanese patients with IBD.
