The purpose of this study was to assess the effects of different daily lengths of physical training on postoperative walking ability and functional performance among elderly inpatients following hip fracture. Fifty-eight eligible elderly patients (mean age 81 years, SD 8) undergoing inpatient rehabilitation after fall-related hip fracture were randomized to receive either 2 units (40 minutes in 29 patients) or 6 units (120 minutes in 29 patients) of daily physical training postoperatively. There were no significant differences in patients' age, preoperative walking ability, type of femoral neck fracture and preoperative QOL functional score (FIM, BI and EQ-5D). All patients commenced the same postoperative rehabilitation program immediately after surgery consisting of bed-side sitting, wheelchair mobilization and progressive muscle strengthening exercises on the second day, followed by weight-bearing exercises and walking between the second and the 14th day. All patients walked with a stick or a rollator at the time of discharge from the hospital after 4 weeks of inhospital rehabilitation. There was no significant difference in the BI, FIM and EQ-5D scores and walking ability between the two groups during 12 weeks postoperatively, however, medical expenses in the 2 units group were decreased by US$ 2,000. Postoperative rehabilitation of elderly patients with femoral neck fracture aims to return the patients to pre-injury conditions as early as possible. This can be achieved with the help of a 2 unit (40 minutes) a day training program.

Japan introduced a mandatory residency program in 2004. Teaching hospitals are now responsible for improving patient safety and the overall teaching environment. Questionnaires were sent to teaching hospitals in Kyushu to evaluate residents' work environments and to ask them about improving patient safety. Questionnaires asked about the work environment, experience with medical errors and adverse events, self-reported work conditions, personal anxiety levels about medical errors, and personal suggestions for decreasing medical errors. One hundred eight questionnaires were mailed, and 76 (70.3%) were returned complete and were analyzed. Most residents in Japan work long hours, feel extremely busy, and are anxious about medical errors; many of them reported personal involvement in medical errors or adverse events. Their suggestions to improve patient safety included improvement of the work environment, establishment of a resident support system, and better organization of medical charts and equipment. Considering residents' viewpoints for patient safety is important to help reduce errors in teaching hospitals.

Objective: We investigated the incidence of side effects related to contrast medium employed in our hospital based on monitoring materials to improve the safety of contrast-enhanced examinations.  Furthermore, we compared the incidence of side effects between the original product and generic drugs to confirm the safety of each preparation.
Methods: The survey period was from April 2007 until March 2011.  Based on the number of patients who underwent contrast-enhanced examinations and that of patients with side effects, we calculated the incidence of side effects in our hospital, and confirmed its annual changes.  Subsequently, we again collected the incidence of side effects per each manufacturer’s preparation employed, and confirmed the state of side effects of individual preparations.  Furthermore, we evaluated the symptoms as side effects, interval until appearance, and treatment for side effects during the data collection period, as well as the subsequent state, symptoms as side effects, and interval until appearance.  The chi square independence test was employed to compare the results among groups.  p<0.05 was regarded as significant (paired test).
Results: There were no changes in the annual incidence of side effects.  There were also no significant differences in the annual incidence of side effects among the preparations.  Furthermore, there were no marked differences in the symptoms, interval until appearance, treatment for side effects, or subsequent state among the preparations.
Conclusion: We investigated the appearance of side effects regarding contrast-enhanced examinations for 4 years.  We confirmed that there were no differences in the incidence of side effects among the preparations.

In Japan, doctors inexperienced stent-graft new devices are required to secure agreement on criteria and choice of the device size in endovascular aneurysm repair (EVAR) from experienced doctors. It was hoped that strict patient selection might reduce the learning curve for initial successes in given procedures. In a leading center in Japan, a number of cases which were scheduled for operation at other institutes were evaluated anatomically. We surveyed the initial success of Zenith AAA system implantation in the remaining cases by inexperienced doctors and evaluated the results. This study aimed to verify the validity of strict patient selection in improving the success rate of inexperienced doctors. We enrolled 112 consecutive patients from 19 institutes, who were scheduled for repair between January and October in 2007. All patients were evaluated on the basis of a less-than-3mm reconstructed CT image. Mean patient age was 76±5.7 years. All cases satisfied the Zenith's anatomic prerequisites. Fifteen cases were excluded for various reasons, the major reason being insufficiency of the proximal landing zone (LZ) length, angle and contour. The second reason was difficulty to approach via the iliac artery. Ninety seven cases were included, of which 17 cases were low-risk candidates for EVAR. Medium-risk seventy two cases requiring some advice to avoid problems with device size, technique of implantation and choice of main-body side. Eight cases were high-risk, requiring the presence of an experienced surgeon. Excluded cases had significantly shorter proximal LZ, larger aortic diameters 15mm below the renal artery and tortuous access routes on preliminary measurement by inexperienced doctor. Perioperative mortality was 0%, while the major complications were injury to the iliac artery in one high-risk case and thromboembolism of the superficial femoral artery in another. Perioperative proximal type I endoleak occurred in 5 cases. In 3 of these cases, the endoleak was eliminated by implantation of a Palmatz stent. In the other 2 cases, it disappeared within a month without additional procedures. These cases had a significantly greater angle between the proximal LZ and the suprarenal aorta and significant amount of mural thromboses in the proximal LZ. Perioperative type III endoleak occurred in 3 cases. In all cases the endoleak was eliminated by additional procedure. Perioperative type II endoleak occurred 8 cases. In 3 of these cases, the endoleak disappeared within a month. In the 5 other cases, the endoleak did not disappear. Mid-term results showed iliac leg thromboembolism in one case and new type II endoleaks in 3 cases. Type II endoleak occurred in cases which had significantly greater angles between the proximal LZ and the aneurysm. The results which were evaluated in our center had excellent perioperative and mid-term outcomes. We think this evaluation system is effective for risk assessment and reduces the learning curve in EVAR. In anatomically marginal cases, it is possible for proximal type I endoleak and injury of the iliac artery to occur. It is impossible to exclude these marginal cases if treatment need for EVAR is a priority. In these cases, lessexperienced operators should be trained in troubleshooting techniques in advance.

BACKGROUND AND OBJECTIVES: There are few reports on renal dysfunction in the remote period after biventricular repair, and biomarkers for early detection of renal dysfunction are not well understood. We examined whether early fluctuation of biomarkers of renal function occurs in the remote period after biventricular repair in patients with congenital heart disease (CHD). METHODS: Fourteen patients with CHD after biventricular repair were included. The examination values obtained by cardiac catheterization test and renal function indices based on blood and urine sampling were compared. RESULTS: The median estimated glomerular filtration rate (eGFR) of creatinine was 113 mL/min/1.73 m2, and the median eGFR of cystatin C was 117 mL/min/1.73 m2. A urine albumin-to-creatinine ratio (UACR) ≥10 mg/gCr was considered a risk factor for cardiovascular disease in 6 (43%) patients. There was a significant difference in right ventricular ejection fraction and deviation in right ventricular end-diastolic volume from the normal value between the 2 groups divided by UACR. Cyanosis before biventricular repair was noted in 2 (25%) patients with UACR < 10 mg/gCr and in 4 (67%) patients with UACR ≥10 mg/gCr. CONCLUSIONS Increased UACR was noted in 43% of patients. In patients with UACR ≥10 mg/gCr, right heart system abnormality was observed, and several patients had cyanosis before radical treatment. Measurement for UACR may be able to detect renal dysfunction early in the postoperative remote period.

Before the introduction of high density barium for contrast studies of the upper gastrointestinal tract, we conducted a survey concerning the adverse reactions to a swallow of barium and barium concentration.
The incidence of side effects rose as the density of barium increased but the effects were transient. There were no cases requiring medical treatment.
Furthermore, the constipation group and the normal group were examined separately.
The ratio of adverse reactions was high in the constipation group even when the barium density was low. In this group stool hardening and delayed excertion were also noticed.
The constancy of barium stool excretion was basically normal, and the barium density had little effect.
The effects of a laxative on the excretion consistency were investigated. The administration of a laxative did not always have a positive affect on excretion. The timing of the administration of the laxative and the amount of water intake should be examined in the future.
We also investigated how the patients feel when they are swallowing barium. We found that whether feel uncomfortable or not depended on the properties of barium rather than its density.
From these results it appears that appropriate guidance is necessary about the use of high density barium, in order to supress the occurrence of side effects, especially in the constipation group.

We report two cases of an abdominal aortic aneurysm, one with congestive heart failure, and the other with a dissecting aortic aneurysm (type IIIb), who underwent an aorto-bifemoral bypass operation under a temporary external axillofemoral bypass. In one patient (Case 1, a 74-year-old male), who had an abdominal aortic aneurysm with congestive heart failure due to aortic valve insufficiency and stenosis, perioperative transesophageal echocardiography demonstrated that, with a temporary external axillofemoral bypass, the regurgitant doppler signal was unchanged during the cross-clamping period of the abdominal aorta. In the other patient (Case 2, a 71-year-old male), who had a dissecting thoracoabdominal aortic aneurysm with the lower abdominal aorta having a true aneurysm formation, the transesophageal echocardiography demonstrated that, with a temporary external axillofemoral bypass, the false lumen of the dissecting thoracic aneurysm had no change in size during the cross-clamping period of the abdominal aorta. Thus, a temporary external axillofemoral bypass might avoid any unfavorable hemodynamic effect during and after the abdominal aortic clamping in patients suffering from an abdominal aortic aneurysm with cardiovascular complications.

  The Association of Radiologists under the umbrella of the Hokkaido Prefectural Federation of Agricultural Cooperatives for Health and Welfare (Hokkaido Koseiren) set up in 2003 a committee with the aim of improving the accuracy of mass health examinations. Recently, the committee reviewed the results of abdominal examinations by sonography performed at the eight hospitals affiliated with the Koseiren during fiscal 2006 that ended March 31, 2007. Of those individuals who underwent thorough health checkups, 91.3% had their abdomen examined by ultrasound. Something anomalous was detected in 68.1% of the examinees and 4.5% needed to undergo closer checkups, the rate of response to which was 74.5%. The detection ratio of cancer by ultrasonography was worked out at 0.048%. The ratio of patients requiring a closer exam to the total and the cancer detection ratio varied widely from hospital to hospital. The wide dispersion was ascribable to the difference in the standard of judgment for indicating closer examinations and the difference in the number of examinees so far as the cancer detection ratio was concerned, from hospital to hospital. A look at the primary findings of anomalies revealed that fatty liver topped the list accounting for 27.4% followed by cholelithiasis with 3.6%. From this, we realized that the abdominal examinations by sonography served to detect cancer and lifestyle-induced health problems as well. Organ-wise, the cancer cases found during the period from 1998 to 2009 broke down as follows: kidney (79 cases), liver (40 cases), pancreas (30 cases), gall bladder (24 cases), others (8 cases) and spleen (none). The cancer detection ratio per year ranged from 0.03 to 0.05% during the period.

Sixteen cases of malignant soft tissue sarcoma (STS; 10 canines and six felines) were treated with a novel triple therapy that combined photodynamic therapy, hyperthermia using indocyanine green with a broadband light source, and local chemotherapy after surgical tumor resection. This triple therapy was called photodynamic hyperthermal chemotherapy (PHCT). In all cases, the surgical margin was insufficient. In one feline case, PHCT was performed without surgical resection. PHCT was performed over an interval of 1 to 2 weeks and was repeated three to 21 times. No severe side effects, including severe skin burns, necrosis, or skin suture rupture, were observed in any of the animals. No disease recurrence was observed in seven out of 10 (70.0%) dogs and three out of six (50.0%) cats over the follow-up periods ranging from 238 to 1901 days. These results suggest that PHCT decreases the risk of STS recurrence. PHCT should therefore be considered an adjuvant therapy for treating companion animals with STS in veterinary medicine.
