The purpose of this study is to examine the validity of muscle fatigue evaluation using maximum voluntary torque (MVT), and to identify the dependence of individual's tolerance for fatigue on the capacity to exert MVT. In 14 young male subjects (10 regular exercisers and 4 sedentary), MVT was measured during isometric knee extension, and voluntary activation (VA), which reflects motor unit activation, was evaluated using the twitch interpolation technique. In addition, the maximum endurance time (ET) was measured, and behavior of the mean power frequency (MPF) and the average rectified value (ARV) of surface EMGs from the vastus lateralis muscle were analyzed during constant force isometric contractions of 60% MVT (short-duration fatigue task; SDF task) and 20% MVT (long-duration fatigue task; LDF task) . Correlations were examined among these five variables.
The results were as follows:
1) Subjects were divided into a high voluntary activation group (HVA group) and a low voluntary activation group (LVA group) . Four sedentary subjects were included in the latter group.
2) MVT was significantly larger in the HVA group than in the LVA group (p<0.01) . A significant positive correlation (r=0.72) was found between MVT and VA (p<0.01) .
3) A significant negative correlation (r=-0.71) was found between MVT and endurance time (ET) for the LDF task (p<0.01) . The ET was significantly longer in the LVA group than in the HVA group (p<0.01) .
4) The MPF of voluntary EMG decreased consistently, as ARV increased during isometric contraction in both tasks (p<0.01), indicating the development of fatigue in the muscle. The final change of MPF relative to the initial value was significantly greater in the SDF task than in the LDF task (p<0.05) .
5) A significant correlation (r=-0.83) was seen between the relative change in MPF and ARV in the SDF task (p<0.01) .
6) For the SDF task, the final change of MPF and ARV relative to the initial value was significantly greater in the LVA group than in the HVA group (p<0.05) .
These results indicate that tolerance for local muscle fatigue usually evaluated as maximum endurance time, may depend on individual differences in VA, the VA, in turn, depending on adapta-tion to exercise, and that there appears to exist a corresponding adaptative strategy of the neuromuscular system during fatiguing contractions. Usefulness of our procedure using the twitch interpolation technique in evaluating muscle fatigue was also suggested.

Idiopathic normal pressure hydrocephalus (iNPH) is a disorder observed in elderly patients causing gait disturbance, urinary incontinence and cognitive impairment. Due to the rapidly aging society, the number of patients with iNPH continues to increase yearly. However, iNPH is often overlooked because of its insidious and variable presentation. In the primary care setting, iNPH can be coincidentally discovered by neuroimaging findings, including disproportionately enlarged subarachnoid space hydrocephalus (DESH). We report two cases of iNPH in the elderly living alone that had different outcomes depending upon the availability of neurosurgery specialists. It is essential for primary care physicians to consult neurosurgeons without delay because prompt diagnosis and treatment can improve the patient's quality of life and prolong their duration of living at home.

Daikenchuto is recorded in Kampo textbooks as a prescription for abdominal disorders. We considered fukuchukan (coldness in the abdomen) as equaling a sensation of coldness centering on the navel, and we examined the usefulness of using Daikenchuto as a medication for this symptom. We administered Daikenchuto to 90 patients who presented with coldness of the navel. The patients were divided into 2 groups:the first group had accompanying digestive symptoms, the second had no accompanying digestive symptoms. We then examined their response rates, and improvement rates for coldness centering on the navel. We also examined the abdominal strength and pulse strength for responders and non-responders, respectively.
The Digestive Symptoms group consisted of 64 patients. In this group, the response rate was 81.3%.The improvement rate of coldness centering on the navel was 92.3% in responders and 41.7% in non-responders, and the difference was highly statistically significant (p<0.001). The Non-digestive Symptoms group consisted of 26 patients. In this group, the response rate was 38.5%. The improvement rate of coldness centering on the navel was 100% in responders and 43.8% in non-responders, and the difference was statistically significant (p=0.022).
In a comparison of all 90 responder and non-responder cases, weak abdominal strength was 62.9% in responders and 42.9% in non-responders, intermediate abdominal strength or above was 37.1% in responders and 57.1% in non-responders, and the difference between abdominal strength and response rate (p=0.076) was non-significant. Weak pulse was 54.8% in responders and 40.7% in non-responders, intermediate pulse strength or above was 45.2% in responders and 59.3% in non-responders, and the difference between pulse strength and response rate(p=0.221) was non-significant. 13 of these cases were above intermediate, for both abdominal strength and pulse strength.
We conclude that for patients presenting with a sensation of coldness centering on the navel, there is a strong possibility that the efficacy of Daikenchuto-syo is suggested, regardless of whether or not there are other digestive symptoms. Moreover, Daikenchuto proved effective in 13 cases where both abdominal strength and pulse strength were above an intermediate level, suggesting that a sensation of coldness centering on the navel can be the key to finding the sensho of Daikenchuto-sho.

The purpose of this clinical investigation is to analyse the growth of the ventricular volumes and the changes of indices of cardiac performance during infancy and childhood. The materials were composed of 129 healthy infants and children (4 months to 13 years of age), who had a history of Kawasaki disease and without any evidence of coronary artery lesion. All the cases underwent cardiac catheterization and cineangiography under sedation. Volumes of the left and right ventricles were calculated by integration methods in tow frames for end-diastole and end-systole from biplane cineangiograms. Left ventricular mass was calculated in 120 infants and children by Rackley's method.
All the volumes and masses were deviled by body surface area in order to normalize the crude values for infants and children of different size. The mean values of left ventricular end-diastolic volume index (LVEDVI), right ventricular end-diastolic volume index (RVEDVI) and stroke index (SI) for each age were less in the younger children than those in the older children, and abrupt stepwise increase was observed at 1 year, 6 years and 10-11 years of age in the values of LVEDVI, RVEDVI and SI.
The infants and chidren were divided into four groups according to age (under 1 year, 1 to 5 years, 6 to 10 years and more than 11 years) . The values of LVEDVI, RVEDVI, SI and LVmass index were less in the younger age groups than those in the older age groups, and the difference of each age groups was statistically significant. The value of left ventricular ejection fraction (LVEF) was less in the youngest group (under 1 year) than those in the another groups (p<0.01) . The value for right ventricular ejection fraction (RVEF) was not significantly different in the age groups. End-systolic pressure-volume ratio was normalized with left ventricular mass (LVESP/ (LVESV/LVmass) ) . This normalized ratio was the lowest in the youngest group (under 1 year) and the highest in the oldest group (more than 11 years) .
As mentioned before, abrupt stepwise increase was observed in the“normal”values of LVEDVI, RVEDVI and SI in infancts and children. The explanation of this fact may be difficult at present. By the evidence of the normalized end-systolic pressure-volume ratio, it can be said that the contractility of the left ventricle in“healthy”infants and children was increased according to age. The reason why the value of LVEF was less in the youngest group than those in the another groups can be attributed to the lower contrac-tility in the youngest group. A possible factor that the value of RVEF was not significantly different between the youngest group and the another groups is; because the right ventricle works under higher pressure during fetal and neonatal period, then the right ventricular performance developed already in infancy.

Objective : Serum albumin is important marker in all aspects of stroke care including rehabilitation. We examined the serum albumin level of stroke patients, and investigated the relation between their serum albumin level and their prognosis. Methods : The serum albumin levels of 295 patients enrolled from 2008 to 2014 were sequentially checked in our hospital and in subsequent rehabilitation hospitals. Functional outcome was measured by functional independence measure (FIM) at the time of discharge from the rehabilitation hospital. Results : In all types (cerebral infarction, cerebral hemorrhage and subarachnoid hemorrhage (SAH)) of apoplexy, serum albumin levels were the highest at the time of admission, temporarily declined after admission, and almost recovered at the time of discharge. In SAH, the serum albumin levels deteriorated at a greater rate than in other types of stroke. In cerebral infarction and cerebral hemorrhage, the lowest serum albumin level was positively correlated with FIM at the time of discharge from the rehabilitation hospital (p<0.001). But, in SAH, there was no significant correlation between the lowest serum albumin level and FIM at the time of discharge (p=0.844). Conclusion : Our data suggest that serum albumin level is associated with the outcome of stroke patients, except for SAH patients. Serum albumin level should be one of the prognostic factors used in stroke patients, but we should consider that SAH patients are exceptional because of other neurological complications.

Objective: It is very important that, to avoid, pharmacists-check medication being taken by patient.  In the Hokkaido University Hospital we used commercial drug identification software at the start of outpatient prescription identification duty and reported the outcome.  Furthermore, we filled in another hand-written check sheet with the drug’s name, whether or not it is used in our hospital, alternative drugs, and the dosage and administration.  Because of the risk of drugs being entered by mistake, we built a database for drug identification and distinguished the outpatient’s prescriptions.  With this system it is possible integrate identification reports and check sheet using one style, automatically.  We also to smoothly rationalize duties by planning correct communication between the medical staff.  At the same time, we analyzed the case that was able to intervene in reasonable use of medical supplies with a past identification report as a result of pharmacists distinguishing outpatient prescriptions.
Design and Methods: This system was constructed using Microsoft® Access, which is a general-purpose database software.  Also, the medical supply database that we used for this system uses “Drugs in Japan Ethical Drugs DB (supervised by Drugs in Japan Forum)” published by JIHO Co., Ltd.
Results: By using this system, we were able to reduce the time required to identify the drugs and make the report.  The result of a questionnaire carried out on doctors and a nurses and medical staff revealed that more than 90% of the respondents claimed, “the report is easy to refer.”  Likewise, we analyzed a report of the previous year and recognized that medical staff could not find the inappropriate use of prescriptions for outpatients in about 17.5%.
Conclusion: This system improved the efficiency of outpatient prescriptions practices, and it became clear that it could be used convincingly as a tool to share appropriate drug information between medical staff and pharmacists, more precisely.  In addition, feedback from medical staff suggested that it might prevent the risk of problems surrounding outpatient prescriptions, from the viewpoint of the pharmacist.

BACKGROUND: Postoperative pain relief can be achieved with various modalities. However, there are only few reports that have analyzed postoperative analgesic techniques in total hip arthroplasty patients. The aim of this retrospective study was to compare the postoperative outcomes of three different analgesic techniques after total hip arthroplasty. METHODS: We retrospectively reviewed the influence of three analgesic techniques on postoperative rehabilitation after total hip arthroplasty in 90 patients divided into three groups (n = 30 patients per group). Postoperative analgesia consisted of continuous epidural analgesia (Epi group), patient-controlled analgesia with morphine (PCA group), or a continuous femoral nerve block (CFNB group). We measured the following parameters relating to postoperative outcome: visual analog scale scores, the use of supplemental analgesia, side effects, length of the hospital stay, plasma D-dimer levels, and the Harris hip score. RESULTS: Each group had low pain scores with no significant differences between the groups. The PCA group had a lower frequency of supplemental analgesia use compared to the Epi and CFNB groups. Side effects (nausea/vomiting, inappetence) and day 7 D-dimer levels were significantly lower in the CFNB group (p < 0.05). There were no significant differences between the groups in terms of the length of the hospital stay or the Harris hip score. CONCLUSIONS: Although there were no clinically significant differences in outcomes between the three groups, the CFNB provided good pain relief which was equal to that of the other analgesics with fewer side effects and lower D-dimer levels in hospitalized patients following total hip arthroplasty.

Background: Massive rotator cuff tears (MRCTs) with subscapularis (SSC) tears cause severe shoulder dysfunction. In the present study, the influence of SSC tears on three-dimensional (3D) shoulder kinematics during scapular plane abduction in patients with MRCTs was examined. Methods: This study included 15 patients who were divided into two groups: supraspinatus (SSP) and infraspinatus (ISP) tears with SSC tear (torn SSC group: 10 shoulders) or without SSC tear (intact SSC group: 5 shoulders). Single-plane fluoroscopic images during scapular plane elevation and computed tomography (CT)-derived 3D bone models were matched to the fluoroscopic images using two-dimensional (2D)/3D registration techniques. Changes in 3D kinematic results were compared. Results: The humeral head center at the beginning of arm elevation was significantly higher in the torn SSC group than in the intact SSC group (1.8±3.4 mm vs. −1.1±1.6 mm, p<0.05). In the torn SSC group, the center of the humeral head migrated superiorly, then significantly downward at 60° arm elevation (p<0.05). In the intact SSC group, significant difference was not observed in the superior-inferior translation of the humeral head between the elevation angles. Conclusions In cases of MRCTs with a torn SSC, the center of the humeral head showed a superior translation at the initial phase of scapular plane abduction followed by inferior translation. These findings indicate the SSC muscle plays an important role in determining the dynamic stability of the glenohumeral joint in a superior-inferior direction in patients with MRCTs.
