Blood glucose disposition rate after intravenous glucose infusion is considered to reflect mainly the rate of cellular glucose uptake, the rate of glucose degradation process and gluconeogenesis. excluding the influense of glucose absorption.
When it is hypothesized that the elevated blood glucose is disposed by constant rate (one-compartment theory), the following formula will be realized.
Ct = A (1— k)t Ct = blood glucose level at t-minutes after infusion
A = initial glucose level after infusion
k = constant glucose disposition index / min
log Ct = log A (1—k) t= log A + t log (1 — k)
This formula demonstrates that logarithm of blood glucose concentration (Ct) is a one-dimensional (linear) function of time t with a slope log (1 — k), and blood glucose disposition index k can be calculated from this slope.
To examine the validity of this hypothesis, 1.5 ml / kg of 20% glucose (0.3g / kg) was infused at rest within 3 minutes into an antecubital vein and plasma glucose was determinned at 1, 3, 5, 10, 15, 20, 30 and 40 min after the cessation of infusion.
In 10 healthy subjects, linear regression coefficient between logarithm of plasma glucose and time t was significantly higher (r= 0.992 ± 0.006, p<0.001) during 5 to 40 min. Calculated k index ranged from 0.78 to 4.54% / min and the correlation between the 1st and the 2nd measurements (n=5) within a week was also significantly high (0.92±0.06, p<0.01). These results highly support the validity of basic formula (one-compartment theory) and practical procedure to measure k index.
The effects of warm water bathing (42 C, 10min) was examined in 7 subjects keeping warmth by blankets. After bathing, k value remained in nearly the same in 4 subjects, decreased in 2 and increased in 1. Although more detailed studies are needed, the effect of single bathing on glucose disposition seems to be not so significant.

To clarify the effects of acupuncture treatment on acute and chronic shoulder-hand syndrome, 20 minutes of manual acupuncture was applied to 14 patients with posthemiplegic shoulder-hand syndrome at the hemiplegic arm and hand (eight points of keiketsu) twice a week for 5 weeks.
Thermographic and laser doppler measurements showed the increases in skin temperature and blood flow of the affected hand. Although manual acupuncture produced long-lasting increases in skin temperature and blood flow of both hands, its effects were inhibited when 10-mg alpha-blocker phentolamine was injected beforehand. After 5 weeks of the acupuncture therapy, the increased skin temperature and blood flow of the affected hand were gradually reduced to normal levels.
Subjective and objective symptoms such as pain, local heating, and swelling showed positive improvement in 10 out of 14 patients after the 5 weeks of acupuncture therapy.
These results may suggest that the shulder-hand syndrome is produced by unknown sympathetic vasodilating mechanisms and that acupuncture plays a therapeutic role through the suppression of increased sympathetic tone.

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.

Introduction : Recommendations from healthcare providers are considered by vaccinees and their parents when they decide whether to receive an immunization. However, in Japan, the attitudes of primary care physicians toward vaccination are unknown. We assessed some practices and recommendations of, and barriers to, primary care physicians regarding vaccinations in Japan.
Methods : A self-administered questionnaire was mailed (in 2012) to 3000 randomly selected physician-members of the Japan Primary Care Association. Excluded were physicians within two years after graduation, living abroad or retired. We described respondent practices, recommendations, and barriers to the provision of routine and voluntary vaccinations.
Results : The overall response rate was 25.8%. The rates at which physicians gave routine and voluntary vaccines in their own practices were 29.0-91.4% and 15.2-89.5%, respectively. The vaccine recommendation rates for routine and voluntary vaccines were 58.2-70.2% and 14.1-50.9%, respectively. The physicians reported that their barriers to recommendation of routine vaccines were vaccination schedule complexity (32.9%), opinions of vaccinees and parents (28.9%), and vaccine safety (27.7%). They also reported that perceived vaccine safety (62.1%), lack of understanding of vaccine-preventable diseases (55.7%), and complexity of vaccine schedules (44.4%) were reasons given by vaccinees and parents for noncompliance. Physicians' barriers to recommendation of voluntary vaccines were cost (45.3%), safety (35.1%), and lack of information (30.1%). They reported that vaccinees and parents expressed concern about cost (61.8%), safety (51.8%), and lack of vaccine information (50.7%).
Conclusion : We clarified practices, recommendations, and barriers to primary care physicians regarding routine and voluntary vaccination in Japan.

At Tokyo Women's Medical University, our curriculum for first-year students is designed to teach the dynamics and etiquette of human relations. During the third year, medical students are expected to anticipate and plan effective therapeutic communication and interaction with patients. A discussion group of 6 students and a member of the human-relations committee first clarify the purpose and develop the training; students then independently participate in human-relations training during the summer vacation. After training, experiences are discussed during class. Although this curriculum has been used for some 10 years, its benefits have been assumed but not validated. We used student reports and questionnaires to examine the effects of this curriculum. The results clearly show that planning and training give the students an opportunity to learn how to establish an effective physician-patient relationship.

The effects of high concentration mineral water bating (31.16g/kg, mainly composed of Na, Ca, Mg chloride and sulfate) were studied in 13 healthy men (44.9±16.3y.o.). The subjects took 41°C, 10min bathing and kept warmth by a blanket for 30min. Blood pressure (BP), Heart rate (HR), cardiac output (CO), total peripheral resistance (TPR) and sublingual temperature by electric thermista as deep body temperature were measured during and after bathing. Skin blood flow by LASER doppler flow meter and venous partial gas pressure and pH were also measured.
Sublingual and forehead temperature was increased significantly by +1.4°C after 10min bathing and +0.9°C increase continued even after 30min. Diastolic BP and TPR were significantly decreased, and HR and CO were significantly increased by +20bpm and +2.7l/min, respectively. Significant increase of skin blood flow was also demonstrated. Significant increase of venous pO2 (+20 Torr) and decrease of pCO2 (-8.0 Torr) suggested the improvement of peripheral oxidative metabolism due to increased CO.
High concentration mineral water bathing was highly effective than simple water bathing probably due to the thick coating effect by binding concentrated minerals with skin furface protein.

Objective: Exercise baths are generally considered to be one of the most appropriate and advantageous rehabilitative therapies, yet their effects have not been comprehensively investigated. The aim of this study is to assess the efficacy of exercise baths on quality of life (QOL).
Methods: The 49 subjects consisted of 20 patients with brain disease, 21 patients with orthopaedic disease, and 8 patients with other diseases (i.e., 7 life-style related diseases and one heat burn). In the present study, all patients were first treated by conventional rehabilitation comprising physical therapy and occupational therapy for 4.2±1.4 weeks. Exercise baths were then added to the rehabilitation program for a further 4.4±1.2 weeks. The subjects were immersed in water at 38°C for 30-60min, twice a week. QOL was evaluated by alterations in the MOS Short-Form 36-item Health Survey (SF-36). We defined the period from admission to exercise bath start as Treatment I, and the period from exercise bath start to discharge (exercise bath finish) as Treatment II. On admission, before and after exercise bath, QOL was evaluated using the SF-36 scores.
Results: We found that the increase of all eight subscales of the SF-36 was smaller in Treatment I period than in Treatment II period. Increases in SF-36 scores were observed in all patients, in all eight domains. Specifically, after exercise baths, increased scores of Physical functioning (PF), Role physical (RP), General health (GH), Vitality (VT), Role emotional (RE) and Mental health (MH) subscales of the SF-36 were observed in the patients with brain disease. Further, after exercise baths, increased scores of PF, RP, Bodily pain (BP), GH, VT, RE and MH subscales of the SF-36 were observed in the patients with orthopedic disease.
Conclusions: It was concluded that exercise baths are an effective non-pharmacological treatment that might facilitate rehabilitation programs.

The purpose of this study is to evaluate MRI findings for the shoulder pain in hemiplegic stroke patients in relation to clinical characteristics. We studied 18 hemiplegic patients with first-ever stroke presenting with shoulder pain in the affected side (mean age±SD=67.6±10.1years ; 8 men and 10 women ; 12 right and 6 left hemiplegia). All patients had shoulder pain during passive movements and 4 also had pain at rest. The mean duration from stroke onset to MRI was 67±42 days. MRI revealed abnormal findings in all patients. Tendinosis of the long head of the biceps and supraspinatus tendon injuries were most frequently found. The tendinosis of the long head of the biceps was related to hemihypesthesia and a reduced range of motion for external rotation of the shoulder. The supraspinatus tendon injuries were related to older age and lower Fugl-Meyer (FM) and Functional Independence Measure (FIM) scores. The mean number of abnormal findings per patient was 3.2±1.4. The patients with more than 3 abnormal findings were significantly older, had shorter duration from stroke onset and lower FM and FIM scores than those with less findings. It was suggested that those patients with more severe paresis might have more abnormal findings on their MRIs for shoulder pain.

Headaches caused by metastatic brain tumors result from dural tension and traction of the sites of nociceptive nerves that originates from displacement of cerebral vessels and intracranial hypertension caused by the tumor. Causes of such headaches also include meningeal irritation resulting from intrathecal dissemination of tumor and carcinomatous meningitis.Treatment of headaches resulting from intracranial hypertension involves alleviation of cerebral edema and reduction of intracranial pressure using hyperosmolar therapy and steroid administration, but treatment is often complicated by a lack of pressure reduction. We encountered 2 cases of headaches with intracranial hypertension that did not improve following hyperosmolar therapy and steroid administration, but resolved with increased opioid dose.In cases where intracranial pressure does not decrease, or for headaches attributed to direct stimulus of intracranial nociceptive nerves rather than intracranial hypertension, attempts to treat the patient with initiation or increased dosage of opioids may prove effective from a clinical standpoint.

Afferent loop syndrome is often difficult to resolve. Among patients with afferent loop syndrome whose data were extracted from databases, 5 patients in whom metal stent placement was attempted were included and evaluated in this study. The procedure was technically successful without any adverse events in all patients. Metal stent(s) was placed with an endoscope in the through-the-scope manner in 4 patients and via a percutaneous route in 1 patient. Obvious clinical efficacy was observed in all patients. Adverse events related to the procedure and stent occlusion during the follow-up period were not observed. Metal stent placement for malignant obstruction of the afferent loop was found to be safe and feasible.
