The purpose of this study was to investigate changes in muscle strength of the quadriceps femoris after intraarticular acupuncture treatment of the affected joint in subjects with unilateral osteoarthritic knee. Isometric muscle strength was measured by standard dynamometry at 90 degree knee flexion when the subjects contracted the quadriceps muscle slowly and maximally without any pain.
In the preliminary experiment, the repeated measurement yielded a high reliability coefficient (correlation coefficient r=0.95, there is no significant difference between the two means) in the affected knee as well as the normal side for 19 patients with osteoarthritic knee.
Nine subjects, whose muscle strength of the affected side had fallen by more than 20% compared with the normal side, participated in the study. An acupuncture needle was inserted into the point where the tenderness of the affected meniscus was marked. The results revealed a noticeable increase in muscle strength of the quadriceps femoris in the affected side from 14.3±2.2kg before acupuncture to 22.9±3.0kg after intraarticular acupuncture (p<0.001), with no significant change in the normal side from 26.0±2.4kg to 27.1±2.8kg (p>0.05).
A hypothesis was formulated that the dicreased muscle strength of the quadriceps femoris in the osteoarthritic knee results from reflex inhibition from joint receptors and that intro-articular acupuncture has a disinhibition effect on this inhibition of the extensor muscle activity.

[Objective] In this study, the pain of receiving acupuncture was evaluated with or without individual finger stalls.
[Design] In a randomized, subject- and operating person-blind, controlled study.
[Methods] Sixteen acupuncturists and same number of normal volunteers participated in this study. Two needles were inserted into each side of the lumbar muscles. The trials were carried out twice using finger stalls and with bare fingers. These trials were performed in random order. Right after the insertion of needles and at the beginning of electrical stimulation, the subjects were asked to answer a questionnaire about the severity and quality of pain on receiving acupuncture. Durations of procedures were measured. We asked the acupuncturists whether they felt any difficulty in performing acupuncture using finger stalls.
[Result] The majority of acupuncturists reported that using the finger stalls during treatment was inconvenient. Although the severity of pain of acupuncture did not significantly differ between that with and that without finger stalls, the average value was slightly higher with finger stalls. The qualities of pain on receiving acupuncture did not significantly differ between the two methods, however, the numbers of selected words differed on some items. The subjects could not recognize the use of individual finger stalls. The use of finger stalls did not influence the duration of the procedure.
[Conclusion] In this study, the qualities of pain on receiving acupuncture did not significantly differ between that with and that without finger stalls. The subjects could not recognize the use of individual finger stalls.

[Objective]To evaluate the efficacy of the different depth of acupuncture on the motor function and the pain with osteoarthritis of the knee.
[Design]Single blind randomized controlled trial.
[Method]Subjects were randomly allocated to one of two groups. Acupuncture needles were inserted about 3mm in the superficial acupuncture group and 10 to 20 mm in the deep acupuncture group. Subjects in both groups received the treatments for ten minutes on ten tender points. Acupuncture sessions were performed once a week for 8 weeks and without treatment 4 weeks.
[Outcome Measures]Pain intensity (visual analogue scale :VAS) , Objective evaluation of the motor function (Timed Up &Go test, 20m walking time, Time of going up and down stairs) and QOL (Western Ontario and MacMaster Universities osteoarthritis index :WOMAC).
All measurements were recorded at baseline, 4th, 8th and 11thweek.
[Result]Motor function improved significantly only in the superficial acupuncture group(P<0.05). The degree of pain decreased significantly in both groups (P<0.05).
[Conclusion]Superficial acupuncture provided the improvements on pain and motor function and contributed to the QOL improvement. Therefore the superficial acupuncture would be suggested to be one of the most effective method for the acupuncture treatment of OA of the knee.

Left ventricular thrombus is a complication of left ventricular dysfunction, including acute myocardial infarction, cardiomyopathy, and severe valvular heart disease. Surgical removal should be considered when a thrombus is mobile, when thromboembolism occurs, and when cardiac function has the potential to improve. Two patients with left ventricular thrombus underwent totally thoracoscopic transatrial thrombectomy. A thrombus developed in the apex of the left ventricle after acute myocardial infarction in one patient (Case 1) and during treatment for congestive heart failure in the other (Case 2). The minimally-invasive transatrial approach requires no sternotomy or left ventriculotomy and is thus particularly beneficial for treating left ventricular dysfunction. Moreover, totally endoscopic surgery confers the advantage of a deep and narrow visual field. Therefore, we consider that this strategy is highly effective for treating left ventricular thrombus.

A 31-day-old infant with total anomalous pulmonary venous drainage (type I-A) suffered from severs left-sided heart failure unable to be weaned from cardiopulmonary bypass (CPB) after total repair. By reopening the vertical vein, the CPB was successfully terminated and the sternum was closed primarily. Percutaneous delayed closure of the vertical vein by lifting up the string which had been encircled the vertical vein at the time of repair was performed 3 days after repair. Systemic arterial pressure and left atrial pressure were unchanged after closure of the vertical vein. Postoperative cardiac study revealed satisfactory result and no left-to-right shunt through the vertical vein.

OBJECTIVE: Ovarian clear cell carcinoma (CCC) is one of histological subtypes showing poor prognosis due to chemoresistance. The association of autophagy-related proteins and clinical implementation in CCC has not been determined. METHODS: The present study investigated whether expression of autophagy-related protein, light chain 3A (LC3A), was related with prognoses in the patients with CCC using immuno-histochemical stainings, and whether inhibition of autophagy modified the sensitivity to cisplatin in CCC cells in vitro. RESULTS: High expression of autophagy-related protein, LC3A, was detected in 78 cases (78%) in all CCC cases. The patients with high LC3A expression showed significantly lower response rate to primary chemotherapy (17% vs. 100%, p<0.010), and had worse progression-free survival (PFS) and overall survival (OS) compared with those with LC3A low expression. Furthermore, multivariate analyses revealed that high expression of LC3A was identified as independent worse prognostic factors for PFS and OS. Inhibition of autophagy protein LC3A using hydroxychloroquine (HCQ) increased sensitivity to cisplatin in CCC cells in vitro. CONCLUSION: High expression of LC3A proteins was associated with lower response to platinum therapy, leading to worse prognoses in CCC. Although further studies are needed to confirm the results, inhibition of autophagy by HCQ was associated with platinum sensitivity. Autophagy protein LC3A could be a promising target for treatment for CCC.

OBJECTIVE: In 2014 World Health Organization criteria, seromucinous carcinoma was defined as a new histological subtype in ovarian carcinomas, but “seromucinous carcinoma” was not defined in endometrial carcinomas. The aim of this study was to identify seromucinous carcinoma resembling ovarian seromucinous carcinoma in endometrial carcinomas, and to evaluate the clinical significance for prognoses of the patients. METHODS: Central pathological review was conducted for patients with endometrioid carcinoma of the endometrium treated by primary surgery at our hospital between 1990 and 2013. RESULTS: Among 340 cases included in the study, no case had all tumor cells resembling ovarian seromucinous carcinoma in all specimens, and 31 cases (9.1%) had seromucinous component in combination with endometrioid carcinomas. Immunohistochemical analysis revealed seromucinous component had positive reactivity for cytokeratin (CK) 7, and negative reactivity for CK20 and caudal type homeobox 2 (CDX2) in all cases. Seromucinous component showed lower immunoreactivity of estrogen receptor and progesterone receptor, compared with endometrioid carcinoma component. Progression-free survival of the cases with seromucinous component was better than those without seromucinous component (p=0.049). CONCLUSION: Seromucinous component was identified in approximately 10% of endometrioid carcinoma, and could be a histological predictor for prognosis.

This case study reports the case of a 72-year-old man who was diagnosed with aortic regurgitation 20 years ago after a medical checkup and received treatment for edema and weight gain for approximately 2 months at the local hospital. The patient was diagnosed with a ruptured Valsalva aneurysm in the noncoronary sinus with right atrium shunting. Two and a half months after the onset, surgical repair was scheduled on a standby basis, and the patient was discharged 14 days postoperatively with a good course. The surgery was completed with fistula closure using a patch via the aortic valve and the right atrial side approaches as well as aortic valve replacement for aortic regurgitation due to uncinate valve leaflet degeneration. The ruptured sinus of the Valsalva aneurysm is an extremely rare disease, which forms a left-to-right shunt that progresses to severe heart failure. Moreover, congenital tissue fragility of the sinus of Valsalva causes this pathogenesis, and rupture prevalently occurs at a relatively young age, up to approximately 40 years. Herein, after a thorough literature review, we report an extremely rare case of an elderly onset at 72 years of age, and a rare disease course in which elective surgery could be performed without rapid heart failure progression.

Since students who would like to study Kampo medicine more have no opportunity to communicate each other in Northern Japanese Universities, we newly started joint study conferences held by medical students in 2013. The objectives of this paper are to report on these annually held student-based Kampo study conferences in the Hokkaido and Tohoku areas, and the ways each university studies Kampo medicine. In the conference, the students reported on their club activities. Then they studied the history of Kampo medicine and simulation of abdominal diagnosis, and performed group work on case reports together. The number of student participants in these conferences has tripled over 3 years from 18 to 58 (for a total of 111 participants). All members were satisfied with the content. And this reflects medical students' need for a wider perception of Kampo medicine, rather than a limited one gained in their university club activities. We hope this conference will play a major role in other nationwide student-based Kampo study conferences in the years to come.

A 70-year-old woman who was bedridden because of right hemiplegia attributable to a history of cerebral hemorrhage underwent surgical thrombectomy for pulmonary embolism four years previously. Symptoms of heart failure appeared one year previously, and she was diagnosed with constrictive pericarditis and had been treated with medication by a previous doctor. In the current situation, she visited the previous doctor with the chief complaint of fever, and pericardial effusion was observed on echocardiography. Cardiac tamponade was suspected and she was transferred to our hospital. She was then diagnosed with purulent pericarditis because purulent fluid was observed during pericardiocentesis drainage. Bacteroides fragilis was isolated from the culture of the abscess. The abscess was resistant to conservative antibiotic therapy ; therefore, we performed a pericardiotomy with a left small thoracotomy. The pleural effusion was found to be negative for culture and the patient exhibited a good postoperative course. Purulent pericarditis is refractory with poor prognosis. An appropriate surgical procedure must be chosen considering the patient's activities of daily living. Here, we report a surgical case wherein we chose the left thoracotomy approach and achieved positive results.
