A 79-year-old woman with degenerative mitral regurgitation and secondary tricuspid regurgitation underwent mitral and tricuspid repair. Massive and intractable endobronchial hemorrhage occurred during weaning from cardiopulmonary bypass (CPB). Bronchoscopic examination during CPB revealed that the right distal bronchus was the probable bleeding point. We then performed a double-lumen endotracheal tube and a bronchial blocker in the distal portion of the right main bronchus. In addition, extracorporeal membrane oxygenation (ECMO) with a heparin-coating system was performed for 11 h, without extra heparinization because of severe hypoxia. The bronchial blocker was removed 14 h later, and the patient was weaned from ECMO 19 h after admission into ICU. Postoperative computed tomography (CT) revealed a pseudoaneurysm of the right pulmonary artery (A5b) corresponding with the probable site of bronchial bleeding (B5). We speculate that a pulmonary artery catheter induced this endobronchial hemorrhage. At 3 months after surgery the patient was doing well with no symptoms of airway bleeding, and her abnormal CT findings had disappeared.

A 65-year-old man was referred to our hospital in April 2003 with a pancreas tumor detected by a thorough medical checkup. Computed tomography (CT) showed swelling of the pancreatic body and tail, and magnetic resonance cholangiopancreatography (MRCP) showed only the main pancreatic duct in the head of the pancreas. Diagnosing autoimmune pancreatitis, we observed the patient without medication. However, one year later CT showed stenosis of the splenic artery and portal vein accompanied by development of collateral circulation around the pancreas. He had no symptoms, and CT showed no changes in the pancreatic swelling.;;He was admitted to our hospital on January 6, 2005, presenting with a history of jaundice which first appeared on January 1, 2005, and increased collateral circulation around the pancreas with pancreatic swelling were seen on CT. We started prednisolone therapy at 40 mg/day for exacerbation of autoimmune pancreatitis. Serum bilirubin levels improved from 11.9 mg/dl to 2.5 mg/dl, and pancreatic swelling also improved four weeks after starting therapy.;;We present a rare case of autoimmune pancreatitis that developed marked collateral circulations.

Pulse wave velocity is widely used as an index of arterial stiffness. The aim of this study is to assess the usefulness of pulse wave velocity as a risk factor in patients who underwent coronary artery bypass grafting. Arterial stiffness was measured by brachial-ankle pulse wave velocity (baPWV) and the ratio of the patient's baPWV to the age-matched normal value was calculated in 42 CABG patients. Age and male/female ratios were 66.7 years and 33/9, respectively. baPWV (1, 820.7±459.8cm/s) was higher in CABG patients than that in age-matched normal value. Preoperatively, the baPWV ratio in the group with the history of cerebrovascular disease was significantly higher than that in the group who had no cerebrovascular disease (p<0.05). In contrast, the baPWV ratio did not correlate to the severity of other cardiovascular diseases. There was one (2.4%) in-hospital death and 23 incidences of postoperative complication in 16 patients. The baPWV ratio in the group with postoperative complications was significantly higher than that in the group with no complications (1.38±0.33 vs. 1.16±0.22; p<0.05). In this study, baPWV in CABG patients was higher compared with that in the age-matched general population, indicating the existence of atherosclerotic vascular changes. The elevated bePWV is also a risk factor of postoperative complications in patients who have undergone CABG.

Objectives:
The purpose of this study is to investigate the stage of chronic kidney disease (CKD) in adenine-induced CKD model rats by serum analyses, and to examine bone mineral density (BMD), bone strength, and microstructure of trabecular and cortical bone in these rats.
Methods:
Eight-week-old, male Wistar rats (n = 42) were divided into 2 groups: those fed a 0.75% adenine diet for 4 weeks until 12 weeks of age to generate CKD model rats (CKD group); and sham rats. The CKD and sham groups were sacrificed at 12, 16, and 20 weeks of age (n = 7 in each group and at 12, 16, and 20 weeks), and various parameters were evaluated, including body weight, renal wet weight, muscle wet weight, renal histology, biochemical tests, BMD, biomechanical testing, and micro-computed tomography (CT). The parameters were compared between the 2 groups at the various time points.
Results:
In the CKD model rats, at 20 weeks of age, serum creatinine, phosphorus, and intact-PTH levels were elevated, and serum calcium levels were normal, indicating that the CKD was stage IV and associated with secondary hyperparathyroidism. Decreased BMDs of the whole body and the femur were observed as bone changes, and micro-CT analysis showed deterioration of bone microstructure of the cortical bone that resulted in decreased bone strength in the cortical and trabecular bone.
Conclusions
These CKD model rats showed stage IV CKD and appear appropriate for evaluating the effects of several treatments for CKD-related osteoporosis and mineral bone disorder.

PURPOSE: High tibial valgus osteotomy (HTO) is a well-established surgical procedure for patients with medial compartment osteoarthritis (OA) of the knee. The hybrid closed-wedge HTO (CWHTO) procedure permits extensive correction in patients with severe deformities or patellofemoral joint OA. The aim of this study was to report the short-term results in a consecutive series of patients treated with hybrid CWHTO. MATERIALS AND METHODS: We retrospectively evaluated the clinical outcomes and radiographic parameters in 29 consecutive knees that underwent hybrid CWTHO to correct medial compartment OA at an average follow-up of 52.6 months. Clinical outcomes were assessed using the Lysholm score and knee scoring system of the Japanese Orthopedic Association (JOA). The Kellgren-Lawrence grading system and pre- and postoperative mechanical axis (MA), femorotibial angle (FTA), posterior tibial slope, and patella height were assessed. RESULTS: The FTA and MA significantly changed from 180.7° to 170.4° and from 22.0° to 60.2°, respectively. No significant differences were observed between the mean pre- and postoperative posterior tibial slope, Insall-Salvati ratio, or Caton-Deschamps index. The postoperative JOA and Lysholm scores significantly improved from 76.7 to 95.8 and from 58.8 to 90.2, respectively. CONCLUSIONS: Satisfactory outcomes can be achieved with hybrid CWHTO in patients with medial OA.

OBJECTIVE: To examine the surgical-pathological predictors of para-aortic lymph node (PAN) metastasis at radical hysterectomy, and for PAN recurrence among women who did not undergo PAN dissection at radical hysterectomy. METHODS: This is a retrospective analysis of a nation-wide cohort study of surgically-treated stage IB–IIB cervical cancer (n=5,620). Multivariate models were used to identify independent surgical-pathological predictors for PAN metastasis/recurrence. RESULTS: There were 120 (2.1%) cases of PAN metastasis at surgery with parametrial involvement (adjusted odds ratio [aOR]=1.65), deep stromal invasion (aOR=2.61), ovarian metastasis (aOR=3.10), and pelvic nodal metastasis (single-node aOR=5.39 and multiple-node aOR=33.5, respectively) being independent risk factors (all, p<0.05). Without any risk factors, the incidence of PAN metastasis was 0.9%, while women exhibiting certain risk factor patterns (>20% of the study population) had PAN metastasis incidences of ≥4%. Among 4,663 clinically PAN-negative cases at surgery, PAN recurrence was seen in 195 (4.2%) cases that was significantly higher than histologically PAN-negative cases (2.5%, p=0.046). In clinically PAN-negative cases, parametrial involvement (adjusted hazard ratio [aHR]=1.67), lympho-vascular space invasion (aHR=1.95), ovarian metastasis (aHR=2.60), and pelvic lymph node metastasis (single-node aHR=2.49 and multiple-node aHR=8.11, respectively) were independently associated with increased risk of PAN recurrence (all, p<0.05). Without any risk factors, 5-year PAN recurrence risk was 0.8%; however, women demonstrating certain risk factor patterns (>15% of the clinically PAN-negative population) had 5-year PAN recurrence risks being ≥8%. CONCLUSION: Surgical-pathological risk factors proposed in this study will be useful to identify women with increased risk of PAN metastasis/recurrence.

Objective:After the start of the Foods with Function Claims system started in April 2015, the number of Foods withFunction Claims has increased every year. As such,the health food market in Japan is expanding and the health foods usedby consumers has been changing. To clarify the influence by which Foods with Function Claims has affected people’seating habits and improved their health, we surveyed people’s recognition and motivations to the Foods with FunctionClaims.Methods:Our survey was conducted with 238 consumers attending a sports club in the Tama area in western Tokyo,Japan.Results:In response to the question recognition of the word “Foods with Function Claims,”43 people(18.1%) responded“I know well,”141 people(59.2%)responded “I have heard it,but I do not know the meaning,”54 people(22.7%)responded“I do not know. I have never heard of it.” In response to the question whether to buy the Foods with Function Claims,77 people (32.4%) responded “I buy if the price is a little higher than not the Foods with Function Claims,”126 people(52.9%) responded “I buy if the price is equal to not the Foods with Function Claims.” In response to the question, 182people(76.5%)responded“I go to the hospital,”40 people(16.8%)responded“I do not go to the hospital and I use the Foodswith Function Claims.”Conclusion: Our results revealed that the recognition of Foods with Function Claims was low. However consumersrecognized that the Foods with Function Claims is worth using. Education to improve recognition for the Foods withFunction Claims is necessary.
