RÉSUMÉ
BACKGROUND/AIMS: This study aimed to examine the diagnostic ability of endoscopic ultrasonography (EUS) for major vascular invasion in pancreatic cancer and to evaluate the relationship between EUS findings and pathological distance. METHODS: In total, 57 consecutive patients who underwent EUS for pancreatic cancer before surgery were retrospectively reviewed. EUS image findings were divided into four types according to the relationship between the tumor and major vessel (types 1 and 2: invasion, types 3 and 4: non-invasion). We also compared the EUS findings and pathologically measured distances between the tumors and evaluated vessels. RESULTS: The sensitivity, specificity, and accuracy of EUS diagnosis for vascular invasion were 89%, 92%, and 91%, respectively, in the veins and 83%, 94%, and 93%, respectively, in the arteries. The pathologically evaluated distances of cases with type 2 EUS findings were significantly shorter than those of cases with type 3 EUS findings in both the major veins (median [interquartile range], 96 [0–742] µm vs. 2,833 [1,076–5,694] µm, p=0.012) and arteries (623 [0–854] µm vs. 3,097 [1,396–6,000] µm, p=0.0061). All cases with a distance of ≥1,000 µm between the tumors and main vessels were correctly diagnosed. CONCLUSIONS: Tumors at a distance ≥1,000 µm from the main vessels were correctly diagnosed by EUS.

The purpose of this study was to clarify the effects of ingesting chloridquellen and bicarbonate spring waters on electrogastrography and heart rate variability in humans. The subjects were ten young adults (average age 21.9 years old). Three and six cycles per minute (cpm) frequency of electrogastrography (EGG) were measured, as well as the high-frequency (HF: 0.15-0.40Hz) components, and the ratio of low-frequency (LF: 0.04-0.15Hz) components to HF components in heart rate variability (HRV) during 90 minutes. The taste of the water and pain or abnormalities in the stomach were also assessed by having the subjects answer a questionnaire. The subjects ingested the spa water or purified water and were asked to respond to the questionnaire after thirty minutes, and they also ingested no water on a different day and were questioned. The EGG-6 cpm frequency, presumably reflecting intestinal activity, did not change under any conditions. The EGG-3 cpm frequency, presumably reflecting stomach activity, significantly increased with bicarbonate spring waters immediately after ingestion and decreased after 30 min. Additionally, the 3 cpm frequency significantly increased with ingestion of purified water over the course of 30 min. The HF components in HRV, presumably reflecting cardiac parasympathetic activity, did not change under any conditions. The ratio of LF to HF components in HRV, presumably reflecting cardiac sympathetic activity, significantly increased with ingestion of purified water immediately and after 15 min, and bicarbonate spring waters after 30 min. There was a difference between ingestion of chloridquellen and purified water in the answers concerning the taste of the water in the questionnaire. These findings suggest that the constituent parts of chloridquellen water and other factors activate stomach and autonomic nervous activities in humans.

We previously reported that in patients with Alzheimer’s disease (AD), the number of baths that patients report taking at their first evaluation at a memory clinic was significantly decreased in comparison to before the onset of dementia. Based on this research, we thought further longitudinal evaluation was needed regarding the relationship between the number of baths, cognitive impairment and depression state after AD progression. In the present study, we reevaluate the number of baths; cognitive function tests (Hasegawa’s Dementia Scale-Revised [HDS-R], Mini Mental State Examination [MMSE] and Wechsler Adult Intelligence Scale-Revised [WAIS-R]); and the depression assessment (Zung Self-rating Depression Scale [SDS]) 1 year after first evaluation.<BR> At the first evaluation, the average number of baths taken by 65 AD patients (16 male, 49 female; range: 64-90 years, average: 79.5±5.6 years), was 5.6±1.6 bathsweek. At the reevaluation, this number had decreased to 4.9±1.9 bathsweek. In the WAIS-R, a significant positive correlation was found between the score change in number of baths and the change in performance intelligence quotient (PIQ) and total intelligence quotient (TIQ). However, no significant correlation was found between the score change in number of baths and the change in HDS-R, MMSE, or verbal intelligence quotient in WAIS-R or SDS.<BR> We further evaluated the present series by dividing the study population into two subtypes: a group of patients in which the number of baths decreased 1 year after the first evaluation, and a group in which there was no change. There were no significant differences in background factors (e.g. average age at first evaluation) between the groups. Although, no significant difference was observed between the groups in number of baths before dementia onset (both were 6.7 timesweek), a significant difference was found at the first evaluation (5.3 bathsweek vs 5.9 bathsweek, respectively). No significant differences were observed between the groups in cognitive function test or depression assessment at the first evaluation. However, on reevaluation the group with the decreased number of baths showed significantly lower PIQ and TIQ scores in WAIS-R and a significantly higher SDS score.<BR> The results of the present study suggested that number of baths decreased along with the progression of AD and the greatest participating factor was the practical dysfunction reflected by the PIQ score in WAIS-R. Furthermore, we considered the existence of two subtypes: patients in whom the number of baths decreases with AD progression and those in whom there is no change.

In Japan, the Hot Springs Law and the Guideline of Analytical Methods of Mineral Springs (revised) classify springs containing 74 Bq/kg of radon as “hot springs” and those with radon levels exceeding 111 Bq/kg as “medical springs” called “radioactive spring”. Radon is a noble gas that easily diffuses in air.<BR> This study evaluates exposure dose due to radon when using a radioactive spring at a spa in the Toriido area, Komono town, Mie district, Mie prefecture.<BR> After bath water was supplied through a pipe from hot spring storage tanks to bathtubs, only 5.3-18.0% of radon remained in the water. Two days later, only 0.3-0.4% of the radon remained in the bath water due to radioactive decay and diffusion into air being increased by bathing and recirculation filtering.<BR> The calculated effective dose from bathing in radioactive hot spring was 2.8-12.0 nSv, and that from drinking radioactive hot spring water was 5.1-23.3 nSv. To determine the total effective dose from use of the hot spring facility that may effects on human health, it is necessary to analyze radon concentrations not only in the water but also the surrounding air.

Radon is a noble gas that easily diffuses in air. This study evaluates exposure dose due to radon when using a radioactive spring at a spa in the Toriido area, Komono town, Mie district, Mie prefecture. After bath water was supplied through a pipe from hot spring storage tanks to bathtubs, only 5.3-18.0% of radon remained in the water. Two days later, only 0.3-0.4% of the radon remained in the bath water due to radioactive decay and diffusion into air being increased by bathing and recirculation filtering. The calculated effective dose from bathing in radioactive hot spring was 2.8-12.0 nSv, and that from drinking radioactive hot spring water was 5.1-23.3 nSv. To determine the total effective dose from use of the hot spring facility that may effects on human health, it is necessary to analyze radon concentrations not only in the water but also the surrounding air.

Because bathing frequency decrease as Alzheimer disease (AD) worsens, we investigated the relation between cognitive disfunction and bathing frequency.<br> We asked AD patients and their caregivers about the number of times the patient bathed per week before onset of dementia and the time of first clinical consultation. We investigated the relation between scores from a cognitive function test (Hasegawa’s Dementia Scale-Revised [HDS-R], the Mini Mental State Examination [MMSE] and Wechsler Adult Intelligence Scale-Revised [WAIS-R]), and a depression assessment (Zung Self-rating Depression Scale [SDS]) and number of baths taken per week.<br> Before onset of dementia, the average number of baths taken by 89 AD patients (26 men, 63 women; range: 63-90 years, average: 79.8 years), was 6.6 times/week. At evaluation time, this number had decreased significantly to 5.3 times/week (p<0.001). A significant positive correlation was found between perfomance Intelligence Quotient (IQ) and total IQ of the WAIS-R and number of baths (p<0.001, p<0.01, respectively). No significant correlation coefficient was found between HDS-R, MMSE, verbal IQ of the WAIS-R and the SDS and number of baths. Reasons of the patients gave for less frequent bathing were that bathing was troublesome or was forgotten and that thermoregulation of bath water had become impossible.<br> The results suggested that in AD patients, number of baths taken decreased with aggravation of cognitive dysfunction and that there were multiple participating factors including memory disturbance, depressive state, and, particularly, executive dysfunction.

The purposes of this study were to analyze the chemical composition of some bath water in a simple alkaline hot spring utilizing a hospital and clarifying the factors that influence the concentration of each component of the hot spring water accompanying the bathing.<br> Water samples were collected in plastic bottles from some bath water and transported to the laboratory. The pH value, electrical conductivity, cations (sodium, potassium, magnesium and calcium ions), anions (fluorine, chlorine, nitrite, nitrate and sulfate ions) and metasilicic and metaboric acids were measured. To investigate the factors that increase concentrations of each component in bathing water, aeration examinations with air or nitrogen gas were continued for one month.<br> The concentrations of sulfate and nitrate ions in the bath water showed an increased tendency compared to those of the hot spring water just after welling up. After aeration with air, the concentration of sulfate ions became higher than that with nitrogen gas. On the contrary, an increase in the concentration of nitrate ions was not found in water aerated with air or nitrogen gas.<br> In conclusion, the oxidation of sulfur in the hot spring water may have caused the density change of the sulfate ions in the bath water. As for the nitrate ions, the increase in the concentration in the bath water seems to have been caused by perspiration during bathing, but not by oxidation for nitrogen in the hot spring water.

The purpose of this study was to clarify effects of the water fall bath on muscle blood flow, muscle hardness at the shoulder and body temperature after muscle contraction in human.<BR> The subjects of this study were eight young males (average 20.4years old). Blood flow and hardness in middle fiber of trapezius were measured using the monitor of spectroscopy and a handy battery-run device, skin blood flow rate using the laser doppler flowmetry, and tympanic temperature using the thermistor during control period 10 minutes, for five minutes during four conditions (40°C water fall bath, massage using the knocking machine, 40°C hot pack and rest) after muscle contraction and moreover 30 minutes. Subjects wore a swimming trunk while these experiments. The ambient temperature and relative humidity were set to 27°C, 42% in control room.<BR> During the water fall bath, the muscle blood flow was tend to increased compared with after muscle contraction. The skin blood flow was increased and the muscle hardness was decreased significantly. During the massage, the skin blood flow was increased and the muscle hardness was decreased significantly. During the hot pack, the muscle hardness was decreased significantly. The tympanic temperature was no changed in three conditions except from the rest.<BR> These findings suggest that water fall bath is lessened the muscle hardness causing increase of the muscle and the skin blood flows. Therefore, the water fall bath can use one of the method to relief muscle fatigue.

<b>Purpose</b><br> This study aimed to clarify the effects of footbath (FB) on motor functions (MFs).<br><b>Subjects</b><br> The study population comprised 26 healthy volunteers (12 males and 14 females; age, 21-30years, Standard Deviation,25.5±2.8).<br><b>Method</b><br> (1) Study design: The footbath group (FBG; 6 males, 8 females) received FB at 42°C for 20 min after 5-min rest. The control group (CG; 6 males, 6 females) was instructed to sit on the chair for 20 min after 5-min rest. (2) Evaluation of MFs: MF was evaluated using the following parameters: long sitting reach (LSR), grips (GP), quadriceps power, stick reaction, and functional reach (FR). MF was evaluated before the rest period (pre-MF) and after load application (post-MF). The results obtained from pre-MF and post-MF assessments were compared. (3) Measurement of tympanic membrane temperature (TM temp) : TM temp was measured every 1 min duimg load application and after the rest period.<br><b>Result</b><br> TM temp: Significant increase in the TM temp in the FBG was observed at 18 min in the males and at 20 min in females.<br> MF before and after FB: (1) Analysis of all 26 cases: There was no significant difference betweenthe pre-MF and post-MF parameters in both the FBG and CG. (2) Analysis of the findings in males only: The post-FR value in the FBG increased significantly as compared to the pre-FR value, although there was no significant difference between the pre-MF and post-MF results in the CG. (3)Analysis of the findings in females only: In the FBG, post-LSR value increased and the post-GP value decreased significantly as compared to the corresponding values, although there was no significant difference between the pre-MF and post-MF in the CG.<br><b>Conclusion</b><br> Our results suggest that FB improves MF in healthy volunteers. Gender ditiference should be considered while establishing effective FB treatment programs in Balneology.

The purpose of this study was to clarify effects of foot bath at 42°C for 10 min on cerebral circulation and mental function in elderly persons. The subjects of this study were 12 elderly persons (average 83.1 years old). Tissue hemoglobin concentration and blood flow at the cerebral frontal cortex were measured using near-infrared spectroscopy and blood pressure and heart rate using an autonomic spygmomanometer during for each 10 minutes before foot bath, during foot bath, and after foot bath. We measured subject's arithmetic speed and mistaken numbers as mental function. During foot bath the blood flow and after foot bath oxyhemoglobin at frontal cortex were significantly increased. Heart rate was significant increased after foot bath. But deoxyhemoglobin and blood pressure did not changed during foot bath. In addition to arithmetic speed and mistaken numbers were same before and after foot bath. These findings suggest that cerebral circulation is changed by foot bath, but mental functions is not before and after foot bath.

The purpose of this study was to clarify the effects of ingesting spa water on electrogastrography and heart rate variability in humans. The subjects were eight youths (average age 22.3 years old). We measured three and six circles per minute (cpm) power of electrogastrography (EGG), the high-frequency (HF: 0.15-0.4Hz) components, and the ratio of low-frequency (LF: 0.04-0.15Hz) components to HF components in heart rate variability (HRV) during 90 minutes. We also assessed the taste of water, pain or abnormalities in the stomach by questionnaire. The subjects ingested the spa water or purified water after thirty minutes, and ingested no water on a different day. The six cpm power of EGG, presumably reflecting instestinal activity, was significantly increased with spa water ingestion. The three cpm power of EGG, presumably reflecting stomach activity, did not change under any conditions. The HF components in HRV, presumably reflecting cardiac parasympathetic activity, tended to increase with ingestion of spa water. The ratio of LF to HF components in HRV, presumably reflecting cardiac sympathetic activity, significantly decreased with ingestion of spa and purified water. There was no difference in the answers of the questionnaire. These findings suggest that spa water ingestion activates instestinal activity, increasing parasympathetic nerve activity and suppressing sympathetic nerve activity in humans.

The purpose of this study was to clarify difference in heating effect of the two types of bathing for the elderly, footbathing at 44°C and full bathing at 40°C.<br>The subjects of this study were nine elderly persons for footbathing (average 73.5 years old) and 10 elderly persons for full bathing (average 77.4 years old). The tympanic temperature was measured using a thermistor, sweat rate using the ventral capsule method, and blood pressure and heart rate using an autonomic spygmomanometer during control period 10 minutes before bathing, for 20 minutes during bathing, and for 10 minutes after bathing. Subjects wore plain clothes while taking a footbath time or swimming trunks while taking a full bathing. The ambient temperature was set to 20°C during the footbath or 26°C during the full bathing.<br>During the footbath, the tympanic temperature increased to 60% that of full bathing and a significant increase of sweat rate was observed. In contrast, during full bathing, a significant rise in systolic blood pressure was observed immediately after bathing started due to hydrostatic pressure and a significant drop of diastolic pressure was observed after bathing due to heating during bathing.<br>These findings suggest that the footbath is safe, does not cause any change in blood pressure and is expected to provide mild warming for the elderly.

This study examined the effect of hot-spring bathing (40 to 41°C) on salivary secretion and salivary secretory IgA (sIgA) in healthy volunteers. Ten volunteers (10 men, average 33.6±9.3 years old) bathed in a hot-spring for 10 minutes.<br>Saliva samples were collected before bathing, during bathing (from 5 to 7 min), and after bathing using the Saxon test. The saliva flow rates and sIgA concentration were determined and then the sIgA secretion rates were calculated.<br>The saliva flow rates increased significantly during the bathing (p<0.02) and decreased after bathing. The sIgA secretion rates during bathing were significantly higher than those before and after bathing (p<0.02).<br>The increases in saliva flow rates and sIgA secretion rates during bathing were considered to indicate the improvement of local immunity in the oral cavity and thus considered to be useful for preventing upper respiratory tract infections.

The purpose of this study was to clarify effects of foot bathing at 44°C for the patients with hemiplegia. The subjects of this study were six patients with hemiplegia (average 71.6 years old) and six healthy volunteers (average 74.3 years old). Blood pressure and heart rate were measured using an autonomic spygmomanometer, tympanic temperature using a thermistor, and sweat rate using the ventrilated capsule method during the control period of 10 minutes before foot bathing, for 20 minutes during foot bathing, and for 10 minutes after foot bathing. Subjects wore a plain clothes while taking a footbath and the ambient temperature was set to 20°C. During foot bathing, heart rate was significantly increased, but blood pressure and pressure-rate product did not changed. Tympanic temperature was no significant changed in both subjects during foot bathing. But a significant increase of sweat rate was observed in patients. In healthy volunteers, in contrast, skin blood flow on the bottom of the foot was significant increased. These findings suggest that regulation system of cardiovascular is slightly declined in the patient, and patient's thermoregulatory system was difficult in healthy humans.
