The patient was a 25-year-old man, who had been stabbed with a weapon siarilar to long ice pick. Thirty minutes later, he was admitted to our emergency center by ambulance. Anchocardiogram on admission revealed moderate pericardial effusion with normal heart function. Contrast medium enhanced computed tomography revealed that the weapon had entered from the left anterolateral chest wall and reached the posterior wall of the aortic root, approximately 1 cm above the left coronary artery orifice, through the left lung. During examinations, he suddenly went into shock and emergency open pericardial drainage was performed immediately. Approximately 400 ml of blood with a clot was removed from the pericardial cavity. After this procedure, there was no continuous bleeding. Subsequently, pseudoaneurysm developed at the aortic root injury site. Twenty seven days later, aortic surgery was performed. The injury site was resected and sutured directly, employing 4-0 polypropylene sutures with felt pledgets. He was discharged 14 days after the operation without any complications.

Prosthetic graft infection after arch replacement surgery is a serious complication that is often resistant to antibiotics. However, graft replacement is difficult and is very invasive. We performed anterior small thoracotomy drainage and intermittent lavage in 2 patients. First, the prosthetic graft was approached via a left third intercostal thoracotomy. After the ablation of infected tissues and cleansing with saline, drains were placed both proximally and distally to the vascular graft. An irrigation withdrawal drain was then implanted in the left thoracic cavity. After surgery, diluted povidone iodine solution, pyoktanin solution, and saline were used for pleural lavage. Case 1 : An 82-year-old man underwent arch replacement for a ruptured aortic arch aneurysm in November 2005. He suffered from high-grade fever from March 2008 and was referred to our hospital from another hospital with a diagnosis of vascular graft infection. A small anterior thoracotomy and drainage were performed on April 9. Pleural lavage with povidone iodine solution was performed 9 days after surgery, then was performed with saline from days 10-13 after surgery. The patient was discharged on postoperative day 30. Case 2 : A 58-year-old man complained of high-grade fever from March 16, 2009. He had undergone arch replacement for an aortic arch aneurysm in 1997. He consulted a physician and was referred to our hospital with a diagnosis of vascular graft infection. Methicillin-sensitive Staphylococcus aureus (MSSA) was identified by blood culture. A small anterior thoracotomy and drainage were performed on March 24. Immediately after surgery pleural lavage was performed with pyoktanin blue solution changing to povidone iodine on postoperative day 10. Pleural lavage was continued until day 34, and the patient was discharged on postoperative day 64. In both cases, drainage and pleural lavage with antibiotic solutions improved the patients' general condition. The infections have not recurred since discharge. Small anterior thoracotomy for graft infection after arch replacement, in addition to being minimally invasive, can avoid the need for a second median sternotomy, and can provide an adequate view of the full length of the arch prosthetic graft.

[Objective]To analyze the situation of clinics that want to employ acupuncturists and masseurs and to obtain basic data to find employment in the clinic in the future.
[Methods]The subjects were 52 clinics that responded to the questionnaire survey saying they wanted to employ acupuncture and massage therapists. They were divided into three groups according to the license (acupuncture group (n = 5), acupuncture &massage group (n = 25), massage group (n = 22)). The situation and the business realities of the clinic were analyzed.
[Results]Clinics with obstetrics and gynecology want to employ only acupuncturists. There were as many employment needs for both acupuncturists and masseurs in clinics with orthopedics and rehabilitation. The employment satisfaction rating is higher for the patient's need standpoint than cost-effectiveness.
[Conclusion]We analyzed the status of clinics that want to employ acupuncturists and masseurs. This study is expected to help promote the employment of medical acupuncturists and masseurs.

Mitral valve replacement (MVR) is an effective method to treat mitral valve regurgitation (MR) associated with hypertrophic obstructive cardiomyopathy (HOCM) because of systolic anterior movement (SAM) of anterior leaflet. We retrospectively investigated results of mitral valve surgery concomitant with septal myectomy for MR with HOCM. Between August 2008 to July 2009, 7 patients underwent septal myectomy. Among them, 6 patients who had moderate or severe MR preoperatively were objects of this study. Pre and post operative clinical conditions, findings of echocardiogram, and operative techniques employed in each patient were reviewed. Four patient successfully underwent mitral valve plasty (MVP) with septal myectomy. One patient needed only septal myectomy because MR subsequently disappeared with resolution of SAM. One patient resulted in MVR after attempted mitral valve plasty (MVP). SAM disappeared in all patients who had MVP, and residual MR was mild or less. Pressure gradient of left ventricular outflow significantly decreased in all cases. All patients discharged hospital uneventfully. Plication of posterior leaflet, anterior leaflet augmentation if necessary, and prudent use of annuloplasty ring seemed to be effective for successful MVP in HOCM patients. MVP is feasible even in patients with MR derived from HOCM.

Minimally invasive surgery is associated with a faster postoperative recovery because of reduced postoperative pain and improved respiratory function, especially in elderly patients. We began using a minimally invasive approach (small parasternal incision) for isolated aortic valve replacement (MICS AVR) from January 2011. Between January 2011 and February 2012, 32 patients underwent MICS AVR surgery. The mean age was 73 years (range 57-85 years) ; 69% were women. MICS AVR was performed through a skin incision of 6.5±0.5 cm along the third intercostal space. Cardiopulmonary bypass was established through the right femoral artery and vein. The patients were cooled to 28°C, the aorta was crossclamped with a flex clamp, and antegrade cardioplegic solution was given into the aortic root or selectively into the coronary ostia. The aortic valve procedure was performed in a standard fashion. If the distance to the aortic valve was too far, we used surgical instruments for minimally invasive surgery. Conversion to a conventional approach was not necessary in any patient. Mean overall operative time was 250±49 min, cardiopulmonary bypass 140±34 min, and crossclamp time 99±22 min. Mean ICU stay was 1.2±0.5 days and length of hospital stay was 10.3±2.2 days. There was no re-operation for bleeding or surgical site infection. MICS AVR was safe and feasible with excellent outcome. The advantages of this procedure include reduced bed rest, decreased postoperative pain, avoidance of deep sternal wound infection, and cosmetically attractive results. We now use the minimally invasive approach whenever possible. We report an early outcome, experience, strategy, and surgical technique.

We experienced the coronary artery bypass grafting (CABG) with essential thrombocythemia (ET). A case is a man of 73 years old. As for him, 3 vessel disease including left main trunk was recognized on coronary angiography, and it was planned CABG. However, we recognized blood cell aberration in blood examination, and it was diagnosed as ET. ET is classed as a chronic myeloproliferative disorder. It has two opposite tendencies, a bleeding tendency and thrombus tendency. Ischemic heart disease to merge ET is acute myocardial infarction by thrombus in case of most, and there are a few cases to need blood circulation reconstruction of coronary artery for angina pectoris. Perioperative hemorrhage and postoperative graft closure become a problem in CABG with ET. With the hydroxycarbamide which is DNA synthesis inhibitor of a platelet count, a function controlled it, and enforced CABG. He doesn't have any cardiac events and complications due to ET for 7 years post CABG. We report this case with a review of the literature.

The aim of this study was to develop a new method for the determination of NO2 levels encountered in clinical settings as well as in environmental studies, using a bi−component atmospheric pressure ionization mass spectrometry(APIMS). Hydrogen (1%) diluted in pure argon was ionized by corona discharge in the first ionization component. Fifty ml of the analyte diluted in 250ml of composite air or carbon dioxide (CO2) was introduced into the second ionization component and analyzed. When composite air was used as the sample carrier gas, NO in the analyte was oxygenated and there was an increase in the NO2 content from that in the original analyte. However, when CO2 was used as the sample carrier gas, the level of NO2 in the analyte could be determined because CO2 did not change the NO2 content from that in the original analyte. A calibration curve with good linearity was obtained using the UG−410 APIMS system, with a regression equation of Y(%)=5.513*10-2 X(ppb) and a detection limit of 0.9ppb. Since APIMS detects NO2 directly within its system, the concentration of NO does not need to be measured. This system may be of great help in the accurate detection and determination of the concentration of low levels of NO2 during inhaled NO therapy

This study was carried out to determine the relationship between health status and physical fitness, and the contribution of each element of physical fitness to the health status of middle-aged and elderly men and women. The subjects were 889 males and females aged 30 to 69 years. Physical fitness tests and medical check ups were performed. According to health status, the subjects were divided into two groups ; the healthy group (HG, n=348) and the unhealthy group (UG, n=207) . Multiple discriminant analysis was applied to the multivariate data. Correct discriminant probabilities of multiple discriminant functions to discriminate the HG and UG were 70.2% and 68.2% for men and women, respectively. These results suggested that there was a relatively strong relationship between health status and the level of physical fitness in both men and women. The contribution of each element of physical fitness to health status was evaluated by correlation coefficients between the discriminant score representing health status, and performance on each element of the physical fitness test and age. Age and muscle endurance contributed significantly to health status in both men and women. In addition, close relationship was seen between health status and elements of cardiorespiratory endurance, balance, and muscle strength in men, while change in physique correlated with health status in women. From these findings, it was concluded that exercise programs for health promotion in middle-aged and elderly people should be provided separately with consideration of the degree to which these specific elements contribute to health status.

STUDY DESIGN: Case-control study. PURPOSE: To evaluate the surgical magnitude and learning curve of "second-generation" total en bloc spondylectomy (TES). OVERVIEW OF LITERATURE: In June 2010, we developed second-generation TES combined with tumor-induced cryoimmunology, which does not require autograft harvesting. METHODS: TES was performed in 63 patients between June 2010 and September 2013. Three groups of patients were evaluated: 20 undergoing surgery in the first year of development of second-generation TES (group I), 20 in the second year (group II), and 23 in the third year (group III). Patient backgrounds showed no remarkable differences. Operating time, intraoperative blood loss, blood transfusion, and postoperative C-reactive protein and creatine phosphokinase were compared among the groups. RESULTS: Mean±standard deviation operating time was 486±130 minutes in group I, 441±85 minutes in group II, and 396±75 minutes in group III. The time was significantly shorter in group III than in group I (p<0.05). Intraoperative blood loss was 901±646 mL in group I, 433±177 mL in group II, and 411±167 mL in group III. Blood loss was significantly lower in groups II and III than in group I (p<0.01). Transfusion was not required in 20 of 23 patients in group III, and mean C-reactive protein levels on postoperative day 3 were significantly lower in this group than in group I (6.12 mg/L vs. 10.07 mg/L; p<0.05). Postoperative creatine phosphokinase levels did not differ among the groups. CONCLUSIONS: TES is associated with a significant learning curve. Thus, second-generation TES can no longer be considered highly invasive.
