Objective: The diagnostic criteria for the metabolic syndrome (MetS) were published in Japan in April 2005. However, there have been no large-scale studies in rural areas to confirm these criteria. We examined the prevalence of MetS in subjects who had undergone a routine medical health checkup at our hospital, located in a rural area. This data was used to investigate the appropriateness of the diagnostic criteria for MetS.Subjects and Methods: The MetS status was examined retrospectively in 2340 subjects (1408 men, 932 women ; mean age 49.6 ± 9.7 years) who underwent a routine medical health checkup at our hospital between April 2004 and March 2005.Results: Of the 1408 men and 932 women, 209 men (14.8%) and 23 women (2.5%) were diagnosed with MetS. Forty-four men (3.1%) and 4 women (0.4%) met all three diagnostic criteria for metabolic disorders. In the female group, only 8.7% of the 932 women met the waist circumference criterion of ≥90 cm. Because this waist circumference criterion was used during the first screening but was not met by most of the women, they were eliminated from our study. Using receiver operating characteristic (ROC) analysis, the cutoff values for waist circumference were 85.0 cm (sensitivity 0.750, specificity 0.564) in men and 79.5 cm (sensitivity 0.787, specificity 0.709) in women. If the women's waist circumference criterion had been set at the value of ≥79.5 cm, this would have resulted in 48 (5.2%) women meeting the criterion.Conclusion: From the viewpoint of preventive medicine, the Japanese male MetS diagnostic criteria are fairly appropriate. However, for the women, the waist circumference criterion of ≥90 cm has been set too high and was not met by most of the female subjects. Therefore, the Japanese MetS criteria for women, particularly the cutoff value for waist circumference, requires further verification.

The purpose of this study was to shed light on the prevalence of the metabolic syndrome (MetS) in a rural community and examine whether or not serum adipocytokine levels are associated with the Diagnostic Criteria for MetS and how many MetS components laid down in the standards subjects have. The subjects were 2,858 people (1,744men and 1,114 women, mean age 49.8+/-9.9 yrs) who had participated in our health screening program between April and December, 2005. After obtaining informed consent from them, we measured serum leptin, adiponectin and high-sensitivity C-reactive protein levels, while performing routine blood tests. In the present study, these measurements were used in combination with the number of MetS components applicable to the conditions of our subjects. Two hundred men (11.5%) and 25 women (2.2%) were diagnosed with MetS. The number of MetS women was extremely small. Those women who were above the standard waist circumference of above 90cm accounted for 8.7% of the total. Thus, most women subjects were excluded as MetS candidates here. The leptin levels of the MetS group were higher than those of the non-MetS group in accordance with the number of applicable components in the diagnostic standards for MetS. Especially, the MetS group which met three MetS criteria showed significantly high leptin levels (p/5=0.0081) of 5.26+/-1.86 (ng/ml) compared to 3.31+/-1.44 (ng/ml) of the non-MetS group with waist circumference below 85cm. On the other hand, no significant difference was noted between the groups in adiponectin level. However, in contrast to leptin levels, adiponectin levels were lower in the group having three MetS components than the non-MetS group 4.37+/-1.57 (ng/ml) as against 5.52+/-3.34 (ng/ml). High-sensitivity CRP levels did not show any significant difference between the two groups.As regards the cutoff value of women's waist circumference, further study needs to be done. It was suggested that serum leptin levels might be closely related to the diagnostic criteria for MetS and the number of MetS components applicable.

We often meet the patient suffer from skin pruritus caused by jaundice. Those patients are treated with various methods and care, but there therapy are often ineffective. Japanese herbal medicine Gosha‒Jinki‒Gan has been successfully used to reduce skin pruritus in two patients caused by jaundice associated with advanced cancer. Case 1: A 68‒yearold man had suffered from pruritus caused by obstructive jaundice associated with cholangioma. He had treated with endoscopic nasobiliary drainage (ENBD) and other methods, but pruritus was not reduced. Gosha‒Jinki‒Gan (7.5g/day) imploved sleep disturbance. Case 2: A 81‒year‒old man had suffered from pruritus caused by jaundice associated with liver cirrhosis and hepatoma. He had treated with various methods, but pruritus was not reduced. Gosha‒Jinki‒Gan (5.0g/day) reduced his Numeric Rating Scale (NRS) of pruritus (10→3). Gosha‒Jinki‒Gan is recommended for skin pruritus due to jaundice.

Cardiac patient simulators are commonly used in Japanese educational institutions; however, most institutions have not established concrete learning objectives or strategies for mastering physical examination of the circulatory system, including cardiac auscultation. In this study, we propose clear learning objectives and strategies for simulator practice for fifth-year medical students who have passed the objective structured clinical examination, and explored their educational effectiveness.
1)The subjects were fifth-year medical students (n=94) at the University of Miyazaki. Learning objectives were the mastery of the sequential physical examination and the ability to distinguish 6 cardiac findings, including normal status. The subjects were evaluated with a checklist before and after lectures and simulator practice.
2)The mean score (maximum score=14) significantly increased from before simulator practice (2.2±0.9) to after simulator practice (11.4±1.5; p<0.001). There was no difference in scores after practice among the cardiac diseases.
3)Before practice more than 50% of subjects could use a stethoscope on only right positions and could indicate only the maximum point of a cardiac murmur; in contrast, after practice more than 90% of the subjects could sequentially describe physical findings and accurately predict cardiac diseases.
4)In a questionnaire administered after practice, 83% of the subjects answered that all physicians should acquire proficiency in cardiac auscultation regardless of their specialty.
Simulator practice with clear learning objectives may help improve clinical examination skills when both time and human resources are limited. The reevaluation of the program's continuing educational effectiveness and the establishment of an iterative learning program will be needed.

Case 1 presented congestive heart failure with atrial fibrillation. Echocardiography and cardiac catheterization demonstrated mitral regurgitation and communications between the right and left coronary arteries and pulmonary artery (PA). The fistula orifice was directly closed and mitral annuloplasty was done at the same time. Case 2 had a history of open mitral commissurotomy for mitral atenosis (MS), and was diagnosed as to be re-MS. Selective coronary angiography (CAG) newly documented an aberrant artery originating from the left coronary artery and draining into the distal right PA. At operation, the origin of the aberrant artery was successfully ligated, and mitral valve was replaced with a prosthetic one. This paper presented relatively rare types of coronary artery fistulae, focusing on the importance of routine CAG before open heart surgery and of consideration on the association of this anomaly in respect to perioperative myocardial protection.

Constrictive pericarditis after open heart surgery is a rare entity that is difficult to diagnose. There are various approaches in the surgical treatment of pericarditis. We performed a pericardiectomy on cardiopulmonary bypass via a median approach with good results. A 67-year-old man underwent mitral valve repair in 2005. He began to experience easy fatigability as well as leg edema beginning in January 2010 for which he was treated medically. The fatigability worsened in July 2012. Echocardiography at that time was unremarkable. However, CT and MRI showed pericardial thickening adjacent to the anterior, posterior, inferior, and left lateral wall of the left ventricle. Bilateral heart catheterization revealed dip and plateau and deep X, Y waves as well as end-diastolic pressure of both chambers approximately equal to the respiratory time. He was diagnosed with constrictive pericarditis and taken to surgery. The chest was entered via median sternotomy and cardiopulmonary bypass was initiated to facilitate complete resection of the pericardium. The left phrenic nerve was visualized and care was taken to avoid damage to the structure. A part of the pericardium was strongly adherent to the epicardium. We elected to perform the waffle procedure. After pericardial resection, cardiac index improved from 1.5 l/min/m2 to 2.7 l/min/m2, and central venous pressure improved from 17 to 10 mmHg. Postoperatively, dip and plateau disappeared as measured via bilateral heart catheterization and diastolic failure improved. In the treatment of constrictive pericarditis, we should resect as much of the pericardium as possible. Depending on the case, this can be facilitated by median sternotomy and cardiopulmonary bypass.

We demonstrated the clinical features and outcome of 87 children with idiopathic thrombocytopenic purpure (ITP). Most of them were younger children with severe thrombocytopenia; 71.3% were under 5 years old and 49.4% had platelet counts below 1×104/μl. Initial treatment consisted of high-dose intravenous immunoglobulin in 60 (69.0%), steroid in 10 (11.5%), and no therapy in 17 (19.5%). More than 90% of the children with platelet counts below 2×104/μl received treatment, but most children with platelet counts above 2×104/μl were observed without treatment. No patients had complications with CNS hemorrhage. Chronic ITP was noted in 17 patients (19.5%). Their mean age was 6 years 3 months compared with 2 years 8 months for the acute patients (p<0.01). But there were no significant differences in sex, platelet count, and initial treatment between chronic ITP and acute ITP. Six (35.3%) out of 17 children with chronic ITP subsequently achieved a spontaneous recovery. As of today, only 3 patients (3% of all patients, and 17.6% of patients with chronic ITP) have platelet counts below 5×104/μl. The overall prognosis and quality of life were excollent. Helicobacter Pylori (H. pylori) infection was found in 7.1% of the chronic patients and 5.3% of the acute patients, but platelet counts of them returned to normal without H. pylori eradication thrapy. It seemed that H. pylodi infection played a minor role in pediatric ITP.

A 86-year-old woman visited us, complaining about sharp abdominal pain she had very morning when she got up. Ultrasound and computer tomography scans of the abdomen revealed notable parietal hypertrophy and swelling of the gallbladder. The old woman was diagnosed with acute cholecystitis and immediately admitted to the hospital. Her condition did not improve on conservative management. Percutaneous transhepatic gallbladder drainage (PTGBD) was performed. The bile thus aspirated was bloody, which led us to suspect necrotizing cholecystitis. Emergency cholecystectomy was done. The abdominal operation found the gallbladder wandering with a torsion of 360 degrees around the gallbladder neck as the axis and the leakage of bile in the abdominal cavity from what could be presumed to be the area where the PTGBD was placed. After the torsion was corrected, the gallbladder was surgically removed. Neither gallstones nor tumors were found in it. There were signs of hemorrhagic necrosis in the mucus membrane. The patient made good progress after the operation and was discharged on the 15th hospital day. Torsion of the gallbladder is a comparatively rare entity and its symptoms are not always specific. Therefore, it defies preoperative diagnosis. In this paper, we report our experience with a case of this disease which presented characteristic radiographic images and discuss the treatment strategies including PTGBD.

Clinical course and outcome of 34 patients with peripheral and visceral artery aneuryms, operated during 1975-1990, were analysed. There were 24 males and 10 females. Ages ranged from 14 to 87, with an average of 55 years. Peripheral aneurysms located most frequently in the lower extremity, and the incidence of various origin of the aneurysms were as follows: 14 in femoral, 5 in popliteal, 4 in internal iliac, 3 in subclavian, 2 in common iliac arteries, and 1 in each of vertebral, radial, splenic, renal and anterior tibial artery. Most common cause of aneurysm was arteriosclerosis. Multiple aneurysms were found in 59% of sclerotic type and in most of these with bilateral aneurysms in the iliac, femoral and popliteal. Ruptured aneurysms were seen in 26% of this series. Most of the aneurysms in the extremities were totally excised without difficulty, while the aneurysms in common iliac and internal iliac were opened with partial excision or obliterated with endoaneurysmorrhaphy. Arterial reconstruction was performed using saphenous vein graft or synthetic vascular graft, excepting that the internal iliac artery itself was not reconstructed. The early operative results were satisfactory, but late results showed two death and three complications of cardiovascular system. Therefore, careful follow up of the postoperative patients was recommended.
