Orthostatic Disregulation (OD, a kind of dysautonomia) is a syndrome which indicates disfunction of vessel contraction reflex during static standing. OD patients often show some symptoms of fainting, dizziness, headache and the like or syncope when they are holding orthostatic posture. OD is more recognized especially in preadolescence and adolescence periods (9-15 yrs.) . Brück & Oltmann (1957), Okuni (1958) etc, have reported details about OD.
The purpose of this study was to obtain and discuss details relating to recent appearance of OD, physique, growth characteristics, cardio-vascular functions and physical fitness on OD children by the questionnaire method and some experiments.
2, 227 children in elementary and junior high school in Yokohama and Kamakura cities as sub jectswere first screened by the questionnaire. And 165 subjects out of 2, 227 were at random selected for data on Schellong standing test, passive head-up tilt and distance running.
The value of 9-29%, which was the ratio of false OD (+) appearance by the questionnaire method in this study, was recognized higher than the value of 5-20% by previous studies'. Physique on false OD (+) children was somewhat lean in comparison with the normal. And they had more height increase than the normal.
In physical fitness, distance running, 50 m dash, broad jump, ball throw, chinning exercise and back pull-over tests, OD children were inferior than the normal.
A concrete datum in syncope for standing was got in this study. When an OD child exhibited syncope, systolic blood pressure became 78 mmHg (rest 120-130 mmHg) and heart rate became 76 beats per minute (standing before syncope 100-110 beats per minute) . T wave in II, aVF and P wave in II, III (depression, negative waves etc.) of ECG varied from resting ECG. Judging from these data about ECG and blood pressure on standing test, passive head-up tilt, it was indicated that a reflex system of vessel contraction on OD child didn't work well, and that the heart of OD child was much stressed by gravity in orthostatic posture and changing posture than the normal.
In addition, a fact was proven that false OD (+) children (39.1% boys and 48.2% girls) didn't like sports and physical activities comparing with the normal (16.4% boys and 23.5% girls), It was statistically significant. Therefore, it is estimated that there is a relationship between appearance of OD and physical activities in daily life.

In the studies of physical motion analysis the multiple photographic method with a stroboscope or the fast motion picture which has been used, are not sufficient to pursue a motion of some kinds of sports and of some hidden physical spot only from one direction and difficult to synchronize picture obtaind from three direction.
To make use of electrical engineering from the points of Physiology and Kinesiology, it is worthy of pursuing a physical motion on three dimensions, up & down, right & left and before & behind at once, and furthermore, physiological phenomena in electrocardiogram and electromyogram with connection to the above analyzer.
For that purpose a physical locomotion pursuit analyzer (SN-type, refered to PLPA later on) was devised.
The present devised analyzer is composed of a three dimensions-accelerometor in a gyroscope, a preamplifier, a integration amplifier and a pen-writing recorder.
As already known in the principle of physics, velocity can be obtained by single integration of acceleration rate and displacement by double integration of a acceleration rate.
In above the PLPA, therefore, acceleration rate, velocity and displacement, each of three dimensions can be determined. Capacity of the present analyzer was as follows; Frequency rate : 1.5-20.0 HZ (Static accelerated component under 1.5 HZ was cut by differentiation circuit of DC-cut), time constant of electrical integration circuit : about 0.2sec.
In the present report the outline of PLPA and some data of our experiments obtained by use of it were dealt.
The problems of the telemetering system of this analyzer and digital exhibition by connection to computer require further study.

The 82 nd and 83 rd National Examination for Physicians' License, which were held in 1988 and 1989 respectively, were evaluated from question to question as well as in all the questions as a whole to set minimum pass scores and analysis “relevance” and “difficulty” in a matrix utilizing a modified Ebel's method.
The evaluators were teachers in different disciplines in nationwide medical schools and teaching hospitals and clinical trainees who had taken and passed the immediate past examinations.
Following data processing, the questionable and difficult questions were on the decrease compared with the preceding year, and it was tentatively concluded that the National Examinations have gradually improved year by year.

PURPOSE: In cardiac 2-[F-18]fluoro-2-deoxy-D-glucose (FDG)-positron emission tomography (PET) examination, interpretation of myocardial viability in the low uptake region (LUR) has been difficult without additional perfusion imaging. We evaluated distribution patterns of FDG at the border zone of the LUR in the cardiac FDG-PET and established a novel parameter for diagnosing myocardial viability and for discriminating the LUR of normal variants. MATERIALS AND METHODS: Cardiac FDG-PET was performed in patients with a myocardial ischemic event (n = 22) and in healthy volunteers (n = 22). Whether the myocardium was not a viable myocardium (not-VM) or an ischemic but viable myocardium (isch-VM) was defined by an echocardiogram under a low dose of dobutamine infusion as the gold standard. FDG images were displayed as gray scaled-bull's eye mappings. FDG-plot profiles for LUR (= true ischemic region in the patients or normal variant region in healthy subjects) were calculated. Maximal values of FDG change at the LUR border zone (a steepness index; S(max) scale/pixel) were compared among not-VM, isch-VM, and normal myocardium. RESULTS: S(max) was significantly higher for n-VM compared to those with isch-VM or normal myocardium (ANOVA). A cut-off value of 0.30 in Smax demonstrated 100% sensitivity and 83% specificity for diagnosing n-VM and isch-VM. S(max) less than 0.23 discriminated LUR in normal myocardium from the LUR in patients with both n-VM and isch-VM with a 94% sensitivity and a 93% specificity. CONCLUSION: S(max) of the LUR in cardiac FDG-PET is a simple and useful parameter to diagnose n-VM and isch-VM, as well as to discriminate thr LUR of normal variants.

Objective:
In 2013, a cohort study aimed to clarify the positive and negative effects of introducing the human papillomavirus (HPV) testing for population-based cervical cancer screening has been launched in Japan. This study included four screenings during the subsequent 7-year follow-up period. We aim to describe the results of the first round of this study on cervical cancer screening here.
Methods:
This study began in September 2013 with recruitment completed in March 2016.Women aged 30–49 years were divided into 2 groups: those who received uterine cervical cytology alone in the first year (control group), or those who received a combination of cytology and HPV testing (intervention group), based on their age. After first screening, women with positive result of cytology or positive HPV test required referral. We summarized the results of the first round of cervical cancer screening.
Results:
Of the 25,074 women who were eligible for the study, 13,845 women (55.2%) were screened with cytology alone; 11,229 women (44.8%) received a combination of cytology and HPV testing. After screening, 407 women (2.9%) in the control group and 1,003 women (8.9%) in the intervention group required referral, respectively. Adding HPV testing increased referral rate significantly (p<0.001).
Conclusion
After first screening, introduction of HPV testing appears to contribute to significantly higher referral rates, suggesting that the number of colposcopies as a detailed examination may increase. These preliminary findings suggest that if HPV testing is introduced into screening, medical institutions need to be prepared for an increasing number of follow-up examinations.

Background:
and Purpose To assess the long-term outcomes of intracranial dural arteriovenous fistula (DAVF) treated with stereotactic radiosurgery (SRS) alone or embolization and SRS (Emb-SRS) and to develop a grading system for predicting DAVF obliteration.
Methods:
This multi-institutional retrospective study included 200 patients with DAVF treated with SRS or Emb-SRS. We investigated the long-term obliteration rate and obliteration-associated factors. We developed a new grading system to estimate the obliteration rate. Additionally, we compared the outcomes of SRS and Emb-SRS by using propensity score matching.
Results:
The 3- and 4-year obliteration rates were 66.3% and 78.8%, respectively. The post-SRS hemorrhage rate was 2%. In the matched cohort, the SRS and Emb-SRS groups did not differ in the rates of obliteration (P=0.54) or post-SRS hemorrhage (P=0.50). In multivariable analysis, DAVF location and cortical venous reflux (CVR) were independently associated with obliteration. The new grading system assigned 2, 1, and 0 points to DAVFs in the anterior skull base or middle fossa, DAVFs with CVR or DAVFs in the superior sagittal sinus or tentorium, and DAVFs without these factors, respectively. Using the total points, patients were stratified into the highest (0 points), intermediate (1 point), or lowest (≥2 points) obliteration rate groups that exhibited 4-year obliteration rates of 94.4%, 71.3%, and 60.4%, respectively (P<0.01).
Conclusions
SRS-based therapy achieved DAVF obliteration in more than three-quarters of the patients at 4 years of age. Our grading system can stratify the obliteration rate and may guide physicians in treatment selection.
