This study aimed to determine the effects of wearing graduated elastic compression stockings (GCSs) on arterial stiffness. The study included 10 healthy men who were randomly assigned to undergo trials with and without GCSs on separate days. Baseline measurements of brachial-ankle pulse wave velocity (baPWV), heart rate, and brachial blood pressure (BP) were obtained in the supine position after the subjects had rested for 20 min without GCSs. The order of the trials (with or without GCSs) was set randomly. During both trials, data for these parameters were collected with the subjects in the supine position, after they had rested for 20 min. After both trials, the brachial BP did not significantly change from the baseline values. baPWV significantly decreased after trials with GCSs (from 1153.0 ± 123.4 to 1078.1 ± 134.3 cm/s, P < 0.05), but no significant difference was observed after trials without GCSs (from 1125.2 ± 118.7 to 1134.5 ± 100.9 cm/s). In addition, changes in volume after trials with GCSs (-74.9 ± 35.3 cm/s) were significantly lower than those after trials without GCSs (+9.3 ± 36.7 cm/s, P < 0.05). baPWV significantly decreased during supine rest on wearing GCSs. This decrease in baPWV was possibly caused by a decrease in arterial stiffness itself and/or a decrease in vascular transmural pressure that may have been due to increase in external pressure on the vasculature.

We performed cardiac resynchronization therapy (CRT) in addition to coronary artery bypass grafting (CABG), mitral valve replacement (MVR) and tricuspid valve annuloplasty (TAP) in a 72-year-old patient with poor cardiac function (New York Heart Association functional class III, ejection fraction 38%), triple coronary vessel disease, and mitral and tricuspid valve insufficiency after three-area old myocardial infarction. Electrocardiography showed no change in the QRS interval after CRT. However, tissue Doppler echocardiography showed synchronicity of the septum and posterior segments in the left ventricle, and that contraction of the septum was in the systolic phase of the cardiac cycle after CRT. New York Heart Association functional class improved from III to I after the operation. CRT of the dyssynchronized myocardium in which ischemia and volume overload were improved by CABG, MVR and TAP may improve regional cardiac function and synchronicity.

The purpose of the present study was to clarify effect of increase in calf pressure on calf venous compliance. The calf pressures were increased by wearing elastic compression stockings with different pressures (Calf pressure 0, 12, 17, 21 mmHg). Healthy twelve people (six men and six women, 43.3±15.3 years) volunteered to participate in this study. Changes in calf venous volume during spine rest were measured by mercury plethysmography. We analyzed the calf venous compliance by inflating the venous collecting cuff to 60 mmHg for 7 min, then decreasing cuff pressure at 1 mmHg/sec (over 1 min) to 0 mmHg, using cuff pressure as an estimate of venous pressure. This method produced pressure-volume curves fitting the quadratic regression (Δlimb volume)=β₀+β₁·(cuff pressure)+β₂·(cuff pressure)², where Δ is change. The higher calf venous compliance and volume were observed in with the higher pressure stocking. These results suggest that higher calf pressure induced by wearing elastic compression stocking increases calf venous compliance and maximum venous outflow.

We performed cardiac resynchronization therapy (CRT) in addition to aortic valve replacement (AVR) in a 74-year-old patient with poor cardiac function (New York Heart Association functional class III, ejection fraction 15%), complete right bundle branch block (CRBBB), left posterior hemiblock (LPH), and aortic valve insufficiency. Tissue Doppler echocardiography showed synchronicity of the septum and posterior segments in the left ventricle, and that contraction of the septum was in the systolic phase of the cardiac cycle after CRT. The New York Heart Association functional class improved from III to I after the operation. CRT of the dyssynchronized myocardium in a patient with CRBBB and LPH can improve regional cardiac function and synchronicity.

We performed cardiac resynchronization therapy (CRT) in addition to mitral valve replacement (MVR) in a 66-year-old patient with dilated cardiomyopathy (DCM) associated with complete left bundle branch block (CLBBB) and mitral valve insufficiency. Tissue Doppler echocardiography showed synchronicity of the septum and lateral wall in the left ventricle after CRT. New York Heart Association functional class improved from III to I after CRT and MVR. CRT of the dyssynchronic myocardium in a patient with DCM associated with CLBBB improves regional cardiac function and synchronicity.

An 82-year-old man was referred to our hospital for heart failure due to severe mitral regurgitation and severe tricuspid regurgitation. We performed mitral annuloplasty and tricuspid annuloplasty (TAP). Three weeks after surgery, he developed hemolytic anemia (HA). Transesophageal echocardiography revealed a defect in the left ventricular outflow tract that communicated directly with right atrium, and the jet was striking with the TAP prosthetic ring. HA was not controlled, so we performed re-operation. The defect was found in the atrioventricular membranous septum. The defect was closed and TAP was performed using an autologous pericardial roll again. We report a rare case of acquired left ventricular to right atrium communication after TAP.

We performed the Senning operation and pulmonary valvotomy in an 11-month-old baby with transposition of the great arteries (TGA) with an intact ventricular septum (IVS), and bicuspid pulmonary valvular stenosis associated with pulmonary hypertension (PH). Preoperative catheterization showed a pressure gradient (PG) between the left ventricle (LV) and main pulmonary artery (MPA) of 35mmHg, mean pulmonary artery pressure (MPAP) of 56mmHg, and pulmonary vascular resistance (PVR) of 11.2unit·m². The pure oxygen inhalation test showed a decrease in MPAP from 56 to 38mmHg, and a decrease in PVR from 11.2 to 5.5 unit·m². We could not perform lung biopsy to determine the surgical indications in terms of PH due to preoperative progressive congestive heart failure in this patient. Postoperative catheterization (28 days after the Senning operation) showed a decrease in PG between the LV and MPA to 8mmHg, and MPAP also decreased to 17mmHg. Two radical operations were possible in this patient. One was the arterial switch operation (ASO), and the other was the atrial switch operation, i. e. the Senning or the Mustard operation. We selected the Senning operation because there was the possibility that the new aortic valve might develop persistent stenosis and regurgitation after ASO and pulmonary valvotomy. The Senning operation may be an alternative in selected patients with TGA with IVS and pulmonary valvular stenosis.

Objective : This study aimed to investigate the changes in the functioning of users of visiting rehabilitation services and related factors. Methods: Among 107 users in 22 visiting rehabilitation centers, we analyzed the data of 80 who completed the 6-month study. Their Functional Independence Measure (FIM), Life-Space Assessment (LSA), and level of caregiver burden (J-ZBI_8) were compared at the commencement of this study, and at 3 and 6 months afterwards. A multiple linear regression analysis was performed to examine the factors related to the variables, which changed over 6 months. Results : Over a period of 6 months from the commencement of the study, we found that FIM and LSA scores significantly improved from 82.4 to 87.3 (p=0.016) and from 9.9 to 12.3 (p=0.05), respectively, in the group who were still within 1 year from the time since onset/injury. A multiple regression analysis revealed that the period of time since onset/injury, independence degree of daily living for the demented elderly, and presence of goal setting for activities of daily living/domestic work significantly influenced changes in total FIM scores (p=0.001, R²=0.32). Furthermore, the change in LSA scores was significantly influenced by gender, presence of cerebrovascular diseases, period of time since onset/injury, number of occupations involved in visiting rehabilitation services, and J-ZBI_8 scores (p=0.0001, R²=0.36). Conclusion : Effective visiting rehabilitation requires having appropriate goals set for daily living activities and the establishment of interprofessional collaboration within visiting rehabilitation centers.

We report an extremely rare case of renal cell carcinoma (RCC) extending into the left atrium through the pulmonary vein next to lung metastasis. The patient was a 76-year-old man. Extirpation of the RCC in the right kidney was carried out. Metastasis to the lungs, mediastinal lymph nodes and the pubis were diagnosed and 4 years later, a myxoma-like tumor was formed in the left atrium by echocardiography. We extirpated of the tumor. During surgery, continuity with the metastatic lesion in the right lung, right inferior pulmonary vein and the left atrium was suggested. Histopathologic examination showed the same histopathology as seen in the RCC.

Introduction: Amyloidosis is a variety of symptoms, such as organ failure and peripheral neuropathy amyroid protein is deposited in the systemic organs. We report a case of ketamine was effective for vulba referred pain in end stage. Case report: A 72-year-old male patient in end-stage primary generalized amyloid light-chain amyloidosis experienced excruciating pain in his genitalia about four times daily, lasting from tens of seconds to three minutes. No abnormal findings were noted in the genitalia. Bowel movement and large amounts of peritoneal dialysis fluid triggered excessive traction of the glans penis, which caused the excruciating pain. Referred pain originating from the pelvic plexus was suspected. Continuous infusion of ketamine was started at 50 mg/day for pain relief, which eliminated his pain, and the patient passed away 17 days later. Conclusion: The reason a small dosage of ketamine was effective, we consider there is a possibility of recovery from central sensitization effect of NMDA receptor antagonist worked effectively.
