[Assessment criteria of lower urinary tract symptom severity for general practitioners].

OBJECTIVES: We conducted a preliminary study to examine the validity of assessment criteria of lower urinary tract symptoms (LUTS) severity for general practitioners (GPs). MATERIALS AND METHODS: This study included 194 patients with LUTS, who visited the urology clinics in three hospitals. In 177 who completed International Prostate Symptom Score (I-PSS), International Consultation on Incontinence Questionnaire : Short-Form (ICIQ-SF), frequency-volume chart, uroflowmetry and post-void residual urine measurement, three overall grades (mild, moderate and severe) of LUTS were determined using the newly-developed assessment criteria for GPs. The relationship between diagnoses and treatments by the urologists, and overall LUTS grades were examined. RESULTS: All of the 70 patients with "severe" grade and 68 (94%) of 72 with "moderate" grade were diagnosed as having urination problems. Sixty-eight (97%) with "severe" grade and 64 (89%) with "moderate" grade were treated with fluid restriction, behavioral therapy, and/or drug therapy. Of 35 with "mild" grade, 17 (49%) were diagnosed as having normal urination. In this grade, eight patients (23%) were treated with fluid restriction and 15 (43%) with drug therapy. CONCLUSIONS: This preliminary study revealed that our criteria of LUTS severity for GPs were useful to determine whether the elderly patients should be treated or not. It is necessary to examine the validity of the criteria in a model in which GPs participate.

Examination of the reliability of the portable calorimeter.

1. The present study was performed in order to determine the reliability of the portable calorimeter. 2. Resting energy expenditure (REE) was measured by two different apparatuses: one was the typical gas analyser, the other was the portable calorimeter. 3. Although there are differences among individuals, unless the subject has been exposed to severe physical activity prior to the measurement, a suitable resting time prior to the measurement of resting metabolic rate is 10 min. 4. For the measurement of resting metabolic rate, fluctuations in respiratory quotient (RQ) are extremely small; there is greater fluctuation due to variations in respiration. Therefore, for the screening of energy consumption, the use of a fixed value for RQ is sufficient when measuring only oxygen uptake. 5. Respiratory fluctuations vary from person to person and it is not possible to make stable measurements in 1 or 2 min. Therefore, a suitable measurement time for resting metabolic rate is from 3 to approximately 6 min. 6. The results indicate that this portable calorimeter is a useful apparatus for measuring REE in the field.

Effect of the moderate exercise on performance in upper/lower limb during long term bed rest.

The purpose of this study was to investigate that considers the influence of the moderate exercise has on the upper limbs and the legs during 21 days head down bed rest. Therefore motor evoked potential (MEP) induced by transcranial magnetic stimulation (TMS) in lower leg muscles of four healthy subjects were investigated before/after and during bed rest. There were no significant differences statistically between soleus MEPs before and after bed rest in all subjects. However there were decreased tendancy in MEPs during non-exercise group. And then there were not change discriminal ability on differential threshold of weight sensory in scale test in all subjects during head down bed rest. Theses results indicate that the assign cognitive performance, sensory in scale for upper limb no changes during and after head down bed rest.
