With advancing age, large conduit arteries (e.g., the aorta and carotid arteries) lose their ability to distend in response to fluctuations in arterial pressure. The impaired buffering or compliance function of the arteries contributes to a number of cardiovascular and autonomic nervous systems disorders, including increased systolic blood pressure and aortic impedance, decreased coronary perfusion, left ventricular hypertrophy, and a blunting of cardiovagal baroreflex sensitivity. Because of the clinical significance of this function, a number of methods have been developed to characterize the elastic property of the arteries. However, there is no consensus as to which method should be used. In regard to the prevention of arterial stiffening, mounting evidence suggests that regular physical activity could retard age-related arterial stiffening. The purpose of this review is to introduce methodologies used to derive arterial stiffness, to describe clinical significance of this measure, and to review the impacts of habitual physical activity on central artery stiffness.

We report a case of Nothnagel syndrome with inattention. A 69-year-old laborer was admitted to our hospital for rehabilitation therapy complaining of gait disturbance a month after the onset of brainstem infarction. He had right oculomotor palsy, ataxia on the left side and upward movement limitation of the left eye. Magnetic resonance imaging demonstrated high signal intensity in the right tegmentum of the midbrain and the medial aspect of the right thalamus on T2-weighted and diffusion weighted images. This lesion involving nuclei in the medial aspect of the right thalamus, which is considered to be closely related with the reticular activating system, might explain his inattention. And it is suggested that the low blood flow in the right basal ganglia and parietal lobe revealed by his SPECT scan, could be related with that as well. We administered rehabilitation programs for his ataxia and inattention. Because diplopia is thought to be difficult to improve, we did not attempt to treat the patient's eye movement limitation. Three months after our intervention, he was able to walk without support. However, his inattention remained. Patients with brainstem infarction are apt to have plural impairments concurrently. In such cases, it is necessary to assess the treatment priority for each impairment adequately. Evidence based guidelines for the assessment of treatment priority would aid in this endeavor and the development of such guidelines is therefore expected.

Background
Female Genital Mutilation (FGM), which can be considered as one of the harmful effects for the health of pregnant women and violence to women, is performed widely as a social custom in some African countries. Therefore, this study aims to clarify the situation of FGM prevalence and a recent trend of African countries by using published health statistics.
Method
Demographic and Health Survey (DHS) full reports in African countries written in English in which topic of FGM is included and whose comparison was possible between the latest report and the one about ten years ago were obtained. And, indicators regarding FGM were compared by countries and years.
Results
Of six countries, the prevalence of FGM in five countries had a trend of decline, and their FGM prevalence rates were higher in rural areas than urban. In these countries, wider decline was seen in younger population. For example, in Tanzania, the prevalence changed from 13.5% to 7.1% in 15-19 years old, and from 22.2% to 21.5% in 45-49 years old between 1996 and 2010, respectively. On the other hand, the FGM prevalence of Nigeria was higher in urban areas than rural, and increased in younger women. Some DHS reported the variety of FGM prevalence by places and ethnic groups even in a country.
Conclusions
In many countries, the decline of FGM prevalence in young women could lead us to expectation of more decreased prevalence in the future. The health education to the young, who will become mothers, could be effective. However, since some countries have different characteristic features in the trend of FGM prevalence, it was suggested that sociocultural background should be individually considered for effective interventions.

Treadmill exercise tolerance test(Modified Bruce Method) was performed with and without warm water bathing (WWB, 41°C, 10min) in 14 healthy aged men and women over 65y. o. (68.6±6.0y.o).
Increase in HR, BP and PRP during exercise was reduced after WWB. Duration of exercise and ST depression and occurrence of arrythmia during treadmill exerecise were significantly improved after WWB. Fatigability of the legs and Borg's index were also decreased aftr WWB. These results indicated the improvement of exercise tolerance after WWB was probably due to the increase in cardiac functions and collagenous viscosity (extensivility) of the musculoskeletal system.

The effects of the bathing on renal function were studied in 12 healthy men (32.3±7.7y. o.). The subjects took 41°C, 10min bathing and kept warm by a blanket for 30min, and then a mixture of 10% para-aminohippurate (PAH, 0.3ml/kg) and 10% sodium thiosulfate (NTS, 80ml) was infused intravenously. Clearance of PAH and NTS was calculated as the index of renal plasma flow (RPF) and glomerular filtration rate (GFR). PAH and NTS clearance test was also done at rest without bathing in another day. Blood Pressure (BP), Heart rate (HR), cardiac output (CO), sublingual temperature by electric thermista as deep body temperature were measured during the experiment. 30min after bathing, sublingual temperature was significantly increased by 0.9°C, and CO by +40%. After bathing, renal plasma flow (PAH clearance) significantly increased from 388.5±158.9ml/min to 572±170.7ml/min. Glomerular filtration rate (NTS clearance) was, however, unchanged from 115.6±37.3ml/min to 119.3±51.3ml/min. Filtration fraction (GFR/RPF) was significantly decreased. These results indicated that GFR was not improved by bathing although CO and RPF was increased by thermal vasodilation effect. The mechanism of unchanged GFR, despite of increased RPF, is probably that glomerular filtration pressure unchanged by thermal vasodilation of glomerular efferent and afferent arterioles.

Objective: Warm water immeresion (WWI) has been customary in Japan as useful thermal therapy. However, a comprehensive investigation of the effects of WWI on internal organs has never been undertaken. The purpose of this study was to examine the effects of single WWI on indocyanine green (ICG) excretion in healthy humans. Subjects: 23 healthy males. (32.6±1.9 [mean±SEM] years) Methods: 1CG was administered intravenously (0.5mg/kg) to calculate excretion rate (ER). ICG injection was given before and after WWI (10min at 41°C). Sublingual temperature (ST), blood pressure (BP), heart rate (HR), and cardiac output (CO) were simultaneously measured by noninvasive methods. Results: Significant changes were observed after WWI. These included an increase in ST, HR, and CO and a decrease in systolic BP (p<0.01). ER significantly decreased from 0.210±0.015 to 0.168±0.009 (p<0.01). Front-back ratio of ICG-ER which was calculated in order to evaluate the effect of aging increased significantly with age (R=0.582, p<0.0001). Conclusion: These results indicate that although CO increased due to the vasodilating effects of WWI, hepatic blood flow decreased after WWI and its response reduced with age even in before middle age.

To determine the influence of “thin”, “normal”, and “obesity” on the motor function and exercise capacity of chronic obstructive pulmonary disease (COPD) patients, as well as whether “obesity” is actually “harmful” for such patients. A total of 103 COPD patients in a stable condition were classified into three groups: a “thin group” (BMI<18.5), an “normal group” (18.5≤BMI<25), and an “obesity group” (BMI≥25). Fourteen patients from each group matched for %FEV_1.0, sex, and age were evaluated. The measurement items were: respiratory function, respiratory muscle strength, lower and upper limb muscle strength, the 30-sec chair-stand test (CS-30), timed up and go test (TUG), 6-minute walking test (6MWT), incremental shuttle walking test (ISWT), Nagasaki university respiratory questionnaire (NRADL), and St. George’s respiratory questionnaire (SGRQ). As a result of comparing the three groups, the %MIP was significantly higher in the obesity compared to thin group (p=0.04). No differences were seen between the groups in the mMRC, %MEP, quadriceps femoris muscle strength (%), CS-30, TUG, 6MWT, ISWT, NRSDL, and SGRQ, but these values showed a tendency to be favorable in the obesity group. The BMI was significantly and positively correlated with the %MIP and NRADL. It was suggested that management of the respiratory muscle strength, exercise tolerance, and ADL when COPD patients are obese rather than thin can be possibly associated with a higher QOL.

Various types of surgical techniques have been reported for the closure of complicated PDA, since Morrow first described an innovatory operative method. At our institute, extracorporeal circulation has been frequently used as a support measure for these operations to ensure the safety of the operation. Ten patients with complicated PDA were operated under extracorporeal circulation. All patients but one were adults. The reason for use of extracorporeal circulation included age, presence of atherosclerosis or calcification of the ductus, short neck ductus, ductal aneurysms, right sided descending aorta and recanalization after previous ligation. The ductus was approached through the left lateral thoracotomy in 8 patients and median sternotomy in 2. The Morrow procedure was performed in 2 patients. No hospital death occurred, although the mean duration of the hospital stay after the operation was longer in these cases than in cases with simple PDA. We conclude that the use of extracorporeal circulation is safe and effective for the closure of complicated PDA.

A 69-year-old man, who had undergone coronary artery bypass grafting using the right gastroepiploic artery 2 years previously, was hospitalized with acute epigastralgia. Gastroscopy showed an early gastric cancer in the greater curvature of the corpus and ultrasonography of the abdomen revealed acute cholecystitis due to a stone impacted in the cystic duct. The subtotal gastrectomy and the cholecystectomy with preservation of the right gastroepiploic artery graft were performed. The surgical margin of the resected specimen was negative for cancer. The postoperative course was uneventful. After coronary artery bypass grafting using the right gastroepiploic artery, annual gastroscopy is recommended.

X type questions have been used for the national medical licensing examination since 1997. At Tsukuba University, X type questions have been used since 1996. We compared X typeand K type questions on the basis of the percentage of correct answers and discrimination power. The average percentage of correct answers was 68.2% for K type questions and 53.1% for X type questions. However, the average discrimination power was +0.227 for K type questions and +0.257 for X type questions. These results indicate that X type questions are more difficult and are suitable for achievement tests. The estimated knowledge quantity was 2.04 for K type questions and 2.32 for X type questions. This suggests that the person writing the questions decreased the essential difficulty of X type questions.
