An isolated huge unruptured aneurysm of the right coronary sinus of Valsalva was detected incidentally in a 47-year-old man. Echocardiography and aortograms revealed severe aortic insufficiency with moderate stenosis, and mild dilatation of the lower ascending aorta without annulo-aortic ectasia. At operation, a sclerotic bicuspid aortic valve was confirmed. These abnormal findings necessitated a reconstruction of the aortic root with a valved conduit and reimplantation of the coronary arteries (Bentall operation with the Carrel patch technique). Pathologic examination of the resected aortic wall showed diffuse sclerotic change and partial medial degeneration.

Objective: The purpose of the present study was to clarify the efficacy of alendronate and raloxifene for preventing bone loss in patients with hip fracture by monitoring bone mineral densities (BMDs) and biochemical markers during the 9-month period after fracture. Patients and Methods: Eighty-two female hip fracture patients from 50 to 99 years old (mean ± SD: 81.6 ± 9.5) were randomly divided into two groups; there were 46 patients in the alendronate-treated group (group ALN) and 36 patients in the raloxifene-treated group (group RLX). Drugs were administered to patients six weeks after their operations. Lumbar spine BMD and neck, trochanter, Ward's and total BMDs of the contralateral proximal femur, serum intact osteocalcin (intact OC), bone-specific alkaline phosphatase (BAP) and urinary N-terminal telopeptide of type I collagen (NTX) were measured just before the start of drug administration and at 9 months thereafter. Results: Twenty-two out of 46 patients in group ALN and 23 out of 36 patients in group RLX completed the study. The most common reason for dropping out was the patient's failure to visit the outpatient clinic. Trochanter BMD in group ALN tended to increase by 8.4% compared with the baseline, and total hip BMD in group RLX showed a significant increase (5.7%), although neck BMD in both groups decreased during the 9 months of treatment (–8.7% for group ALN and –4.2% for group RLX compared with the baseline). Spine BMD did not change significantly in eithr group. Serum BAP and urinary NTX decreased significantly in both groups. Serum intact OC did not change significantly. Conclusions: Both alendronate and raloxifene have a favorable effect on trochanter and total BMDs of the contralateral proximal femur in the short period after hip fracture. However, both drugs could not prevent bone loss in the femoral neck during the 9 months of treatment.

Primary cardiac tumors are comparatively rare. Primary cardiac angiosarcoma is the most common cardiac malignant tumor and the most common site of this tumor is in the right atrium. It is usually difficult to diagnose and treat this condition before death. The present case of primary cardiac angiosarcoma was located in the left atrium, which is very rare. A cardiac malignant tumor was suspected in this 56-year-old man based on chest MRI examination. The operation was performed successfully but its outcome was very poor.

Postoperative quantitative evaluation of left internal thoracic artery (LITA) grafts is usually performed by angiography, scintigraphy and Doppler flowire. However it is difficult to observe the characteristics of the intima of the LITA graft. The purpose of this study was to evaluate the characteristics and quantity of plaque of intima of LITA grafts in 6 cases after coronary artery bypass surgery using an intra-vascular ultrasound device (IVUS). There was no stenosis or calcification of LITA grafts on angiography. However we found atherosclerotic plaque in all LITA grafts by IVUS. Characteristics of plaque were eccentric in all cases, and soft, hard and mixed plaque were found. The average minimal lumen diameter of LITA grafts was 2.6±0.2mm. The average lumen area of LITA grafts was 5.4±0.7mm2. The rate of plaque area was 37.1±5.9%. The eccentric arteriosclerotic plaques were seen in all cases, contradicting the established theory that LITA do not form arteriosclerosis easily. We suggest that IVUS is an effective follow-up device for evaluating the morphological findings and quantitative evaluation of LITA graft in a timely manner.

The incidence of fever in children admitted to general hospitals is very high. Provision of adequate nutrition and fluid supplements to febrile children is very important, but with some children it is difficult to maintain an adequate intake. To address this problem, we devised a new ‘febrile children's menu’, utilizing preparation methods and foods to produce a palatable menu for patients with fever.
We introduced this ‘febrile children's menu‘ on January 6, 2011, providing it to 109 patients (age range: 1 to 8 years, average age: 3.3±1.9 years) over the ensuing 3-month period. We provided a mean 4.0±2.9 meals per day to each patient during their febrile stage (≥37.5°C). To evaluate the usefulness of the ‘febrile children's menu’, we investigated eating rates during the febrile period in all patients who had been provided with the menu, and performed a questiomaire survey on their parents/guardians. The mean eating rates during the febrile period were 39±30% for main meals, and 28±22% for side dishes. No significant difference was seen in the eating rates during the febrile period recorded over the 2-month period prior to introduction of the new menu to 112 febrile children (age range: 1 to 8 years, average age: 3.3±2.1 years), 39±30% for main meals, and 29±22% for side dishes. The questionnaire survey was responded by 43 parents/guardians (a recovery rate of 39%). The ‘febrile children's menu’ was assessed as ‘good’ by 67% of respondents, representing an overall favourable impression from the parents/guardians. With reference to the survey results, we will attempt to further improve the ‘febrile children's menu’ with the aim of increasing eating rates during the febrile period.

1) In 2004, Shinshu University School of Medicine started a program for third-year medical students to experience nursing services during both the day and night shifts. The program included lectures on nursing sciences before practice and debriefing sessions after practice.2) Most students viewed this program favorably and felt that the night-shift training was particular meaningful. They also had favorable opinions about the nurses who taught them.3) Some practical issues remain to be solved, such as security during the night shift and the possible excessive burden upon nurses.

We describe an extremely rare case of advanced pure primary ovarian squamous cell carcinoma (SCC), treated by adjuvant chemotherapy with dose-dense paclitaxel combined with carboplatin (dd-TC) plus the combination chemotherapy with irinotecan and cisplatin (CPT-P), with long-term recurrence-free survival. A 71-year-old woman complaining of lower abdominal pain was referred to our hospital and a 7-cm-diameter solid tumor was identified. She was diagnosed with a left ovarian tumor that was highly suspicious for malignancy based on ultrasonography, magnetic resonance imaging, and contrast-enhanced computed tomography. Bilateral salpingo-oophorectomy, low-anterior colon resection, and colostomy were performed. Intra- and post-operative histopathological diagnosis revealed International Federation of Gynecology and Obstetrics stage IIIc well-differentiated pure ovarian SCC. As adjuvant chemotherapy, 2 courses of dd-TC were administered, followed by 3 courses of CPT-P; the patient then underwent 4 additional courses of dd-TC. Both regimens were effective and there has been no recurrence or metastasis thus far in the 5 years since the operation.

Endoscopic ultrasound-guided biliary drainage (EUS-BD), EUS-guided choledochoduodenostomy (EUS-CDS), and EUS-guided hepaticogastrostomy (EUS-HGS) can effectively palliate obstructive jaundice, but have not been well established yet. The incidence of complications is about 30% in EUSBD and higher for EUS-HGS. Several complications have been reported such as bleeding, perforation and peritonitis. Bleeding occurs due to puncture of portal vein, hepatic vein and artery, and we should use color Doppler. When a cautery dilator is used for fistula dilation, burn effects may cause delayed bleeding. Endoscopic hemostasis is only effective for anastomotic bleeding and embolization with interventional radiology technique is required for pseudo aneurysm. There are some types of perforation: failed stent placement after puncture or fistula dilation, double puncture during CDS procedure, and stent migration. Peritonitis with perforation requires surgery and can be fatal. Stent migration before mature fistula formation causes severe peritonitis because EUS-BD makes fistula between two unattached organs. Stents with flaps or long covered self-expandable metallic stents (cSEMSs) are effective to prevent migration. Recent development of lumen apposing stents may reduce early migration in EUS-CDS. Peritonitis without migration can be due to 1) leakage of bile juice or gastric/duodenal contents during EUS-BD or 2) leakage along the placed stent. We should make procedure time as short as possible, and cSEMSs reduce bile leak along the stent by occluding the dilated fistula. In summary, we should understand the mechanism of complications and the technique to prevent and manage complications. Development of dedicated devices to increase the success rate and reduce complications is required.

Percutaneous transhepatic biliary drainage (PTBD) is an established procedure for biliary obstruction. However, duodenobiliary or jejunobiliary reflux of the intestinal contents through a PTBD catheter sometimes causes recurrent catheter obstruction or cholangitis. A 64-year-old female patient with a history of choledochojejunostomy was referred to our department with acute cholangitis due to choledochojejunal anastomotic obstruction. Emergent PTBD was performed, but frequent obstructions of the catheter due to the reflux of intestinal contents complicated the post-PTBD course. We therefore introduced a catheter with an antireflux mechanism to prevent jejunobiliary reflux. A commercially available catheter was modified; side holes were made at 1 cm and 5 to 10 cm (1 cm apart) from the tip of the catheter, and the catheter was ligated with a nylon thread just proximal to the first side hole. Using this novel "antireflux PTBD technique," jejunobiliary reflux was prevented successfully, resulting in a longer patency of the catheter.

OBJECTIVES: Sarcopenia and osteoporosis affects activities of daily living and quality of elderly people. However, little is known about its impact on elderly locomotor diseases, such as osteoporotic vertebral fracture (OVF). There is no report investigating the influence of both sarcopenia and osteoporosis on outcomes of OVF. This study aimed to evaluate the clinical outcomes of OVF in elderly patients from sarcopenic perspectives. METHODS: This prospective study was conducted with 396 patients, aged 65 years or more, hospitalized for the treatment of OVF (mean age, 81.9 ± 7.1 years; 111 males, 285 females). The primary outcome was the Japanese Orthopaedic Association (JOA) score for lumbar disease (at first visit, hospital discharge, and 1 year after treatment) and Barthel index (at the same time and before hospitalization). The second outcome was living place after discharge. Susceptibility to sarcopenia and osteoporosis were evaluated and clinical results of conservative treatment were compared. RESULTS: Sarcopenia significantly affected Barthel index at first visit and discharge. Sarcopenia patients had significantly higher rate for discharge to nursing home and living in nursing home after 1 year than patients without sarcopenia. Osteoporosis significantly affected the JOA score at the first visit and the Barthel index before hospitalization, at the first visit, discharge, and after 1 year. Osteoporosis did not affect the living place at discharge and after 1 year. CONCLUSIONS: Sarcopenia and osteoporosis affected outcomes of conservative treatment for OVF; moreover, sarcopenia affected the living place of OVF patients at discharge and after 1 year.
