The incidence of wound infection and delayed wound healing was greater in neonates and infants less than 3 months old who had undergone open heart surgery through a median sternotomy than in older patients. To reduce these problems, we stopped using continuous absorbable braided suture for skin and subcutaneous tissue closure in August 2005, and used interrupted non-absorbable monofilament suture instead. Around the same time, we adopted hydrocolloid dressing as a substitute for gauze dressing. We evaluated the effectiveness of wound management by comparing 28 patients who had undergone surgery before August 2005 with 22 patients who underwent surgery after that date. The age at surgery was 45±30 and 21±23 days, respectively. The patients in the earlier period were significantly older than in the later period. There were no significant differences in body weight at surgery, operating time, or cardiopulmonary bypass time between the groups. The time for wound closure was 30±11 and 22±4 min, respectively, and the patients were hospitalized after surgery for 61±41 and 44±31 days. Both were significantly shorter in the later group of patients. There was a single case of mediastinitis, in the earlier period. Wound infection or delayed wound healing occurred in 8 patients in the earlier period and in 3 patients in the later period. The only 4 patients who required wound resuturing were all in the earlier period. The incidence of wound infection and delayed wound healing tended to be low in the later period. We believe that interrupted non-absorbable monofilament sutures improved the wound microcirculation and that the hydrocolloid dressing accelerated wound healing via its moisturizing and heat-retention action, pH buffering ability, and bacteriostatic activity, and that all these contributed to the better outcomes in the later period.

We reviewed our experience of tricuspid valve surgery for tricuspid regurgitation in hypoplastic left heart syndrome (HLHS) in terms of surgical timing, surgical procedures and long-term results. From May 1991 to July 2010, 105 classic HLHS patients underwent cardiac surgery, 28 of whom underwent a total of 31 tricuspid valve surgical procedures. Tricuspid valve surgery was performed in cases of moderate or more tricuspid regurgitation (TR). Type of the first tricuspid valve surgery was as follows : Annuloplasty in 15 patients, annuloplasty+commissure closure in 7 patients, commissure closure in 2 patients, edge-to-edge repair in 2 patients, tricuspid valve replacement in 2 patients. Three patients underwent re-operation because of progression of TR. Two of them underwent tricuspid valve repair and one of them underwent tricuspid valve replacement. Follow-up was 60.1±53.0 months. Freedom from moderate or more TR after tricuspid valve surgery was 50.9% at 1 year, 42.0% at 3 years, 36.0% at 5 years. Among 17 patients who achieved total cavopulmonary connection procedure, 35.2% of patients had moderate or more TR, but central venous pressure (9.1±2.2 mmHg), cardiac index (3.5±6.8 l/min/m²), arterial oxygen saturation (94.2±1.7%) showed as good hemodynamics after a Fontan procedure as non-tricuspid valve surgery cases. Appropriately timed aggressive tricuspid valve surgery yielded as good long-term results as HLHS without tricuspid valve surgery.

A 36-year-old previously healthy woman with cardiomegaly on a routine chest X-ray was given a diagnosis of primary chylopericardium after pericardial puncture revealed milky effusion. Endoscopy-assisted ligation of the thoracic duct and creation of a pericardial window was performed. The operation was greatly facilitated by the preoperative three-dimensional CT scan with lymphangiography that precisely demonstrated the distribution of the thoracic duct and other lymphatic ducts.

Objectives : Many reports have investigated the work environment of physicians and reported the association between work environment, burnout, and the quality of medical care. We aimed to determine the key to improving the work environment by analyzing the results of a Japanese survey for young cardiovascular surgeons. Methods : A survey on work environment was performed among the young members of The Japanese Society for Cardiovascular Surgery (≤40 years of age) to measure their job satisfaction for 9 items : operation, perioperative work, number of hours working or sleeping, board affairs (application or renewal of board certification), motivation, salary, days off, quality of life, and mental status. Univariate and multivariate analyses using 16 factors for the work environment (age, number of years in practice, gender, subspecialty, board certification in surgery, board certification in cardiovascular surgery, primary practice hospital, workdays and nights on duty in a primary practice setting, workdays and nights on duty outside primary practice, total annual income, overtime work hours, overtime entitlement, gap in overtime work and entitlement, and presence of an intensive care unit [ICU] managed by ICU physicians) were performed to identify the risk factors for dissatisfaction. Results : The survey was completed by 327 of 1,304 (25.1% response rate) young members of the Japanese Society for Cardiovascular Surgery. The respondents had an average of 8.5±3.5 years in practice, and 292 (89.3%) respondents were male. Only 14.2% of the responding young surgeons reported no dissatisfaction in any items. In all items, the young surgeons were most satisfied with operation (34.6% of all responders). Age, years in practice, female gender, board certification in surgery, working at a university hospital, workdays in a primary practice setting, and workdays outside a primary practice setting were identified as significant factors for dissatisfaction, while a subspecialty in vascular surgery, total annual income, board certification in cardiovascular surgery, and the presence of an ICU managed by ICU physicians were identified as significant factors against dissatisfaction in the work environment. Conclusions : Our analyses of the survey results identified a number of risk factors for dissatisfaction in the work environment among young cardiovascular surgeons. Regarding the quality of medical care, respondents hoped for a reduced burden on surgeons and the establishment of a work-shift system in the cardiovascular department and an interdisciplinary team including an ICU physician. Multidimensional analyses including job satisfaction, rewards as training, and a quantitative evaluation of the quality of medical care will be necessary to clarify the corresponding relationship between consumers and providers of cardiovascular surgery in the work environment.

Introduction：Respiratory failures are categorized into types I and II. To our knowledge, we report the first case of pulmonary rehabilitation in a patient with systemic sclerosis/polymyositis overlap syndrome who developed type II respiratory failure.Methods：The patient was a 77-year-old woman who had received treatment for systemic sclerosis and polymyositis at another hospital. When she visited our hospital to obtain a second opinion, she suddenly lost consciousness and underwent trachea intubation because of typeⅡrespiratory failure. She received physical therapy on the third day of hospitalization and underwent a tracheotomy on the 16th day. As her thoracic movement was markedly restricted, we started physical training. After she was weaned off from the ventilator on the 43rd day, we performed muscular strength training and aerobic exercise. No exacerbation of CO2 storage was observed even if chest motion training was performed. She was discharged on the 72nd day and advised to wear retina®．Administration of therapeutic drugs such as steroids was maintained at the same dose.Conclusion：Physical therapy, such as chest mobilization, was effective for marked restriction of chest movement in a patient who had both polymyositis and systemic sclerosis.

Objectives: Locomotive syndrome (LS) leads to reduced physical function and a high risk of becoming bedridden.Grip strength serves as an indicator of upper limb and overall physical function. Rheumatoid arthritis (RA) patients with reduced grip strength frequently show finger and wrist joint inflammation. The purpose of this study was to verify grip strength as an evaluation tool for physical function and LS in RA patients. Methods: As part of an ongoing multicenter observational study, 591 consecutive RA patients whose background information was available, including data for the 25-question Geriatric Locomotive Function Scale (GLFS-25) and grip strength, were examined. LS was defined as a GLFS-25 score ≥ 16 points. Finger and wrist joint inflammation were defined as tender or swollen joints. Results: Among the 591 patients, 244 (41.3%) patients had LS, and 167 (28.3%) were male. Receiver operating characteristic curve analysis yielded cut-off values of grip strength for LS of 24 kg (specificity 72.2%; sensitivity 62.7%) for males and 17 kg (specificity 65.7%; sensitivity 67.6%) for females. Multivariable logistic regression analysis revealed a significant association of grip strength with LS, even after adjusting for finger and wrist joint inflammation. Conclusions LS was significantly associated with grip strength, even after adjusting for the presence of finger and wrist joint inflammation. We recommend adopting grip strength measurement as a screening tool for evaluating LS and guiding interventions.
