A 76-year-old man who suffered from consistent back pain was admitted for anti-hypertensive therapy to strictly manage the early thrombosed acute type A aortic dissection (AAAD). On admission, his blood pressure could not be controlled well ; soon he complained of recurrent severe back pain. The second thoracoabdominal enhanced computed tomography revealed the progression of AAAD from DeBakey type II to type I with thrombosed pseudolumen at the descending thoracic aorta ; therefore, emergent surgical intervention by primary central repair was conducted. Paraplegia was diagnosed eight hours after surgery, then cerebrospinal fluid drainage and intravenous administration of Naloxone were started immediately followed by keeping the systemic blood pressure more than 120 mmHg. However, paraplegia had never improved and been persistent with neurological deficit of the lower extremities. We herein report a complicated surgical case of an AAAD patient with paraplegia and review the complex clinical settings.

The method of cardioplegic myocardial protection is often controversial for re-cardiotomy after a coronary artery bypass grafting (CABG). A 69-year-old woman with a history of three previous surgeries consisting of closed mitral commissurotomy (CMC), dual valve replacement (DVR), and CABG underwent mitral valve replacement (MVR) and CABG for perivalvular leakage (PVL). As a result, the bilateral coronary ostium and the bypass graft to the right coronary artery (RCA) were totally occluded. The left internal thoracic artery (LITA) graft to the left anterior descending (LAD) coronary artery was the only inflow to the left coronary artery system and the right coronary artery system developed collateral inflow. Cardioplegia was carried out by performing a temporary anastomosis graft on the saphenous vein graft (SVG) in the left anterior descending coronary artery and a new bypass graft in the RCA was used for the administration of cardioplegic solution with no complications. There are various strategies for cardioplegic myocardial protection. The best method should be selected depending on the patient characteristics and condition.

OBJECTIVE: The aim of the present study was to assess prognostic factors for patients with locally advanced cervical cancer treated with radiotherapy as the primary treatment and to assess the posttreatment cut-off levels of squamous cell carcinoma antigen (SCC-Ag) to predict three-year overall survival (OS) rates. METHODS: One hundred and twenty-eight patients with cervical squamous cell carcinoma (International Federation of Gynecology and Obstetrics [FIGO] stage IIB-IVA) treated using radiotherapy or concurrent chemoradiotherapy were identified. Of these patients, 116 who had SCC-Ag levels >1.5 ng/mL prior to treatment were analyzed retrospectively. RESULTS: Median age was 68 years (range, 27 to 79 years). The complete response rate was 70.7% and the three-year OS rate was 61.1%. The median levels of pretreatment and posttreatment SCC-Ag were 11.5 ng/mL (range, 1.6 to 310.0 ng/mL) and 0.9 ng/mL (range, 0.4 to 41.0 ng/mL), respectively. Multivariate analysis showed that pretreatment anemia (p=0.041), pelvic lymph node metastasis (p=0.016) and posttreatment SCC-Ag levels (p=0.001) were independent prognostic factors for three-year OS. The SCC-Ag level cut-off point for three-year OS rates, calculated using a receiver operating characteristic curve, was 1.15 ng/mL (sensitivity, 80.0%; specificity, 74.0%). CONCLUSION: Pretreatment anemia and pelvic lymph node metastasis are poor prognostic factors in locally advanced cervical cancer. Furthermore, posttreatment SCC-Ag levels <1.15 ng/mL predicted better three-year OS rates.

OBJECTIVE: In the present study, we evaluated changes in CA-125 cut-off values predictive of complete interval debulking surgery (IDS) after neoadjuvant chemotherapy (NAC) using receiver operating characteristic (ROC) analysis. METHODS: This retrospective single-institution study included patients with International Federation of Gynecology and Obstetrics (FIGO) stage III epithelial ovarian cancer and a pre-NAC serum CA-125 level of greater than 40 U/mL who were treated with neoadjuvant platinum-based chemotherapy followed by IDS between 1994 and 2009. Logistic regression analysis was used to evaluate univariate and independent multivariate associations with the effect of clinical, pathological, and CA-125 parameters on complete IDS, and ROC analysis was used to determine potential cut-off values of CA-125 for prediction of the possibility of complete IDS. RESULTS: Seventy-five patients were identified. Complete IDS was achieved in 46 (61.3%) patients and non-complete IDS was observed 29 (38.7%). Median pre-NAC CA-125 level was 639 U/mL (range, 57 to 6,539 U/mL) in the complete IDS group and 1,427 U/mL (range, 45 to 10,989 U/mL) in the non-complete IDS group. Median pre-IDS CA-125 level was 15 U/mL (range, 2 to 60 U/mL) in the complete IDS group and 53 U/mL (range, 5 to 980 U/mL) in the non-complete IDS group (p<0.001). Multivariate analyses performed with complete IDS as the endpoint revealed only pre-IDS CA-125 as an independent predictor. The odds ratio of non-complete IDS was 10.861 when the pre-IDS CA-125 level was greater than 20 U/mL. CONCLUSION: The present data suggest that in the setting of IDS after platinum-based NAC for advanced ovarian cancer, a pre-IDS CA-125 level less than 20 U/mL is an independent predictor of complete IDS.

OBJECTIVE: The purpose of the present study was to elucidate the incidence of deep venous thrombosis (DVT) before treatment in ovarian cancer and the appropriate cut-off value of D-dimer (DD) for the diagnosis of DVT. METHODS: Between July 2007 and October 2008, eighty seven patients with presumed ovarian cancer (final diagnosis: ovarian cancer, n=59; borderline malignancy, n=28) were enrolled. Measurement of DD levels and subsequent venous ultrasonography were performed before treatment. RESULTS: The mean DD level was 4.1 microg/mL. Subsequent venous ultrasonography revealed DVT in 14 of 87 (16.1%) patients (ovarian cancer, 12 cases; borderline malignancy, 2 cases). None were found to have developed DVT if they had a DD level of <1.5 microg/mL. If 1.5 microg/mL was used as a cut-off value for DD levels to diagnose DVT, sensitivity, specificity, positive predictive value, and negative predictive value were 100%, 61.6%, 33.3%, and 100%. There was noclinical onset of postoperative pulmonary thromboembolism. CONCLUSION: Our data suggest that presumed ovarian cancer patients with at least more than 1.5 microg/mL should be examined using venous ultrasonogaphy to detect DVT.

BACKGROUND : Norm-referenced equations to predict the 6-minute walk distance (6MWD) in healthy Japanese subjects have not been established. The current study aimed to determine the reference values for 6MWD in healthy Japanese adults.
METHODS : Ninety-seven healthy Japanese men and women aged 40-79 years were recruited from Kyoto city using posters and flyers. Measurements of 6MWD were performed twice on an indoor 30 m track with 20 minutes rest between the two tests. Before performing the tests, age, gender, height, body weight, waist circumference, a questionnaire for health status, spirometry, and a 12-lead electrocardiogram were recorded. The 6MWD was measured following guidelines published in 2002 by the American Thoracic Society.
RESULTS : The mean age of the study subjects was 57.0±9.4, and 63 of the 97 subjects were female. The mean 6MWD for all subjects was 672±83 m, with a range of 483-903 m. The 6MWD is significantly correlated with age, height, waist circumference, forced vital capacity (FVC), and forced expiratory volume in one second (FEV1). A multiple linear model showed age, waist circumference, and FVC were significantly associated with 6MWD and the model explained 35% of the variability in 6MWD. When FVC was replaced by height, the regression model also explained 32% of the variation. The measured 6MWD of Japanese subjects was similar to the predicted 6MWD using the equations derived from Caucasian subjects.
CONCLUSIONS : The 6MWD was affected to a substantial degree by age, waist circumference, height, and FVC in healthy Japanese adults.

Atherosclerotic morbidity of the ascending aorta is associated with an increased risk of perioperative cerebral damage during cardiac surgery. To minimize the risk, we developed a refined method for occluding the diseased ascending aorta. From April 2005 to December 2007, 18 patients underwent cardiac surgery. Just before aortic cross-clamping, the aorta was opened during brief circulatory arrest in order to flush out any possible remaining atheromatous debris. The specially designed intra-aortic occluder was applied to an extremely calcified aorta. There were no hospital mortalities or cerebrovascular accidents. In conclusion, our technique can greatly contribute to the prevention of embolic complications in patients with a severely diseased ascending aorta.

The aim of the present study is to characterize the burden of parents who care for their children with disabilities with the use of a Japanese version of the Zarit Caregiver Burden Interview (J-ZBI) that has been successfully used to quantify the caregiver burden for caring for the disabled elderly. We performed a survey in which questionnaires including the J-ZBI (adapted for the subjects of this study) were given to 135 parents of children in a school for the physically challenged. We obtained 69 valid responses. For the parents, the mean J-ZBI score was 25.6 points and the mean CES-D score was 10.8 points. A lowered QOL for these parents was suggested by the finding that the mean SF-36 score was lower than for other persons of the same year and age in Japan. The parents reported physical strain more frequently than mental stress as the main caregiver burden. According to the parent group's mean J-ZBI score, we classified them into either a heavier or a lighter burden group. The parents who were in a state of depression as judged by the CES-D were more frequently found in the heavier burden group, while those with children who showed complete or modified independence in more items of FIM were more frequent in the lighter burden group. Services to support the physical aspects of parents caring for children with disabilities would reduce their caregiver burden effectively.

A 59-year-old man presented with sporadic febrile illness. Echocardiography showed multiple vegetations on the mitral valve. Blood culture yielded Viridans streptococci. Mitral valve replacement was performed, and a high dose of penicillin G sodium (24 million U/day) was administrated for 4 weeks postoperatively. On the 28th postoperative day, the patient developed severe back pain and bloody sputum. Chest CT showed a false aneurysm of the distal aortic arch (5.5cm). The patient was placed on cardiopulmonary bypass with the arterial return in the mid-aortic arch. The aneurysm was resected and replaced with a Dacron tube during deep hypothermic circulatory arrest. The aortic wall was interspersed with mobile nodules that appeared to be colonized. The aorto-pulmonary fistula was directly closed. The whole procedure was carried out through the 4th intercostal space. The tissue culture was negative but histopathology suggested a persistent inflammatory process. Excavating aortic sepsis may occur following active endocarditis. Even if cardiac infection is controlled, continuous search should be undertaken for possible dilatation in remote parts of the arterial system.

We evaluated the surgical strategy for thoracic aortic aneurysm associated with abdominal aortic aneurysm. From January 1982 to March 1999, 24 consecutive patients underwent surgical treatment for thoracic aortic aneurysm with abdominal aortic aneurysm. Staged operation was performed if one was only slightly dilated, but extensive operation was needed if the size of both aneurysms was greater than 6cm. In cases of thoracic aortic aneurysm with abdominal aortic aneurysm up to 4cm in size, surgical treatment was performed only for the thoracic aortic aneurysm. Circulatory support during operation was established from the ascending aorta, and circulatory arrest with deep hypothermia and retrograde cerebral perfusion were used for brain protection during surgery for thoracic aortic arch aneurysm. Hospital mortality was 12.5% (3/24 cases). The causes of death were cerebral infarction and respiratory failure. Antegrade systemic perfusion and aortic no-touch technique were an effective method of surgery for thoracic aortic aneurysm with abdominal aortic aneurysm to avoid perioperative embolism and major complications. We successfully performed staged operation, but regular radiographic follow-up was needed.
