A 27-year-old woman was given a diagnosis of infectious endocarditis with severe tricuspid regurgitation. Despite adequate antibiotics therapy, her general condition did not improve, and moreover multiple pulmonary abscesses were detected by computed tomography. Therefore surgery was indicated. Surgery consisted of removal of vegetation and tricuspid valve plasty with autologous pericardial patch augmentation of the anterior leaflet. Tricuspid valve plasty was carried out without prosthetic materials. Her postoperative course was uneventful with only mild tricuspid regurgitation. One year after surgery, neither recurrence of infection nor worsening of tricuspid regurgitation was noted. This method could be a useful technique for young patients with severe infection.

In the presence of Leriche syndrome, the lower extremities are perfused by collateral flow from internal mammary arteries. If an internal mammary artery graft is used in coronary artery surgery, an acute ischemic limb will develop postoperatively. A 52-year-old man was admitted to our department with bilateral claudication. Multidetector row computed tomography with contrast showed total occlusion of the infrarenal abdominal aorta and rich collateral flow to the lower extremities from internal mammary arteries. Cardiac angiography revealed three-vessel disease. Simultaneous coronary artery bypass grafting and an ascending aorto-bifemoral bypass were performed without cardiopulmonary bypass. Postoperative computed tomography angiography showed that grafts to the coronary and bifemoral arteries were patent. This combined procedure is useful for patients with coronary artery disease and aortoiliac occlusive disease. This procedure without cardiopulmonary bypass has not previously been reported.

A system for Physiology Educator Accreditation was established by the Physiological Society of Japan in 2013 and then implemented. The accreditation process starts by the applicant participating in the education program during the society’s annual meeting, after which the applicant’s teaching and research experiences are reviewed. The education program consists of model lectures to learn teaching skills and lectures to obtain up-to-date knowledge about physiology. The main purpose of the system is to provide an opportunity to obtain a wide range of knowledge and skills for physiology teaching for teachers working at medical universities and universities of life sciences and for young researchers aiming for a tenure-track academic position.

In recent years, the incidence of proximal femur fractures has been increasing with the aging of the population. There has been a growing number of those patients who injure on the other side of the hip at later date. We studied the relationship between proximal femurfractures and knee osteoarthritis, which is one of the diseases preceding fractures.
We surveyed 234 and 17 patients hospitalized with unilateral and bilateral fractures, respectively at Atsumi Hoapital from April 2008 to March 2011. The research covered sex, age, the cause of injury, the period until they had proximal femur fractures on the other side, bilateral-fracture rate, incidence rates of diseases (cerebrovascular, eye and respiratory), knee osteoarthritis, dementia, diabetes and other forms of fracture.
As a result, we confirmed the connection between knee osteoarthritis and bilateral fractures. There was every indication that knee osteoarthritis may be a major factor which leads to bilateral fractures. All patients with bilateral fracture injured resulting from falls.
We believe it is important to take an approach on the treatment of hip fractures and prevention of knee osteoarthritis and falling.

Congenital quadricuspid aortic valve is a very rare malformation. Most cases have been discovered as an incidental finding at aortic valve surgery or at autopsy. It frequently evolves to aortic regurgitation, which can manifest in adulthood and may require surgical treatment. A 66-year-old man was admitted because of dysprea. Echocardiogram revealed aortic regurgitation, mitral regurgitation, and tricuspid regurgitation. We performed aortic valve replacement, mitral annuloplasty, and tricuspid annuloplasty successfully. The aortic valve showed one large, two intermediate and one smaller cusp, which were classified as typed by Hurwitz's classification. An accessory cusp was situated between the right and left coronary cusps. No coronary abnormality was involved. The postoperative course was uneventful and he is doing well 6 months after operation.

We report 4 cases of valvular injury following nonpenetrating cardiac trauma in 3 men and 1 woman ranging in age from 24 to 72 years. In all cases the cause of trauma was blunt chest trauma. One patient was operated in 4h, but the other 3 patients were operated on more than 6 months after the accidents. Lacerated aortic cusp was observed in 2 patients, ruptured anterior papillary muscle of mitral valve, and ruptured chordae tendinae of the tricuspid vale were observed in 1 patient each respectively. Three patients underwent valve replacement (2 aortic and 1 mitral valves), and another patient underwent chordoplasty in the tricuspid valve. Their post-operative courses were uneventful. Careful observation, such as echocardiography, were required following the blunt chest trauma.

A 47-year-old man had suffered from high grade fever and dyspnea for 10 days. He was transferred to our hospital in a condition of shock. Echocardiography showed severe diffuse hypokinesis of left ventricle (EF 21%), and multiple mobile thrombi in the left ventricle. Under a diagnosis of LV thrombi due to acute myocarditis, transatrial removal of LV thrombi was performed using video-assisted cardioscopy. He was weaned from cardiopulmonary bypass under IABP support. Postoperatively, he suffered from thromboembolism of the cerebral and right brachial artery. Thrombectomy of the right brachial artery and anticoagulation therapy was performed. IABP was removed on POD 3, and he no longer needed respiratory control on POD 4. Echocardiography on POD 6 showed marked improvement of the LV contraction (EF 52%). After rehabilitation, he was discharged on POD 23 on foot. Video-assisted cardioscopy allowed transatrial removal of LV thrombi, and preserved left ventricular function by avoiding ventriculotomy. Perioperative thromboembolism must be taken care of for a patient with multiple LV thrombi.

Oxycodone controlled-release (CR) tablets are used as a first-line opioid analgesic for cancer pain. However, use of oxycodone CR tablets is associated with toxicities such as drowsiness and constipation, leading to deterioration of the quality of life (QOL), especially in patients with gynecologic cancer. In contrast, fentanyl has a superior toxicity profile while still showing a strong analgesic effect. Although fentanyl has been approved for switching from opioid, there have been no Japanese studies of patients with gynecologic cancer who were switched to transdermal fentanyl after experiencing toxicity during therapy with oxycodone CR. More importantly early introduction of palliative therapy for pain has not been adopted routinely in the management of gynecologic cancer. Thus, it appears that treatment for patients with gynecologic cancer remains unsatisfactory at present. We conducted research into improvement of the toxicity profile and pain control with the aim of improving QOL for patients with gynecologic cancer. We showed that pain, drowsiness, and constipation could be significantly improved in gynecologic cancer patients as a result of switching to transdermal fentanyl therapy at an early stage.

OBJECTIVE: To assess the use of colony-stimulating factors (CSFs) in patients with ovarian cancer who receive adjuvant paclitaxel and carboplatin chemotherapy in clinical practice and to assess whether the frequency of CSF use differs among hospitals in Japan. METHODS: CSF use in patients with ovarian cancer who received first-line paclitaxel and carboplatin was analyzed retrospectively using data from the Japanese hospitalization payment system. RESULTS: A total of 1,050 patients at 104 hospitals were identified. The median age was 60 years (range, 22 to 88 years). Of these, 163 patients (15.5%) were diagnosed with neutropenia and 134 patients (12.8%) received CSFs. Among the patients who received CSFs, 125 (93%) received them for the treatment of neutropenia without fever and 1 received them for febrile neutropenia. In total, CSFs were administered for 272 cycles of chemotherapy. Among them, CSFs were used as treatment for neutropenia without fever in 259 cycles (95%), as prophylaxis (primary or secondary) in 12 cycles (4%), and as treatment for febrile neutropenia in 1 cycle. Among hospitals, a median of 4.0% of patients received CSFs with an interquartile range of 25% (Q1, 0%; Q3, 25%). A logistic random effects model showed that the variation in the proportion of patients receiving CSFs among the 104 hospitals was 2.0 (p<0.001), suggesting that the use of CSFs varied across hospitals. CONCLUSION: Most patients received CSFs for neutropenia without fever. Standardized and evidence-based use of CSFs is critically required among hospitals in Japan.
