Ten patients with primary hypothyroidism (aged 32--66 yr), replaced on constant daily doses of L-T4 (mean +/- SD, 1.90 +/- 0.22 micrograms/kg BW), were used to examine seasonal variations in serum levels of thyroid-related hormones for a period of 14 months. Basal and peak TSH concentrations after TRH (500 micrograms) were higher in winter than in summer.(More)
We made an attempt to express a complaint of sleep disturbance by a self-rating scale of radar chart mode. The questionnaire for sleep disturbance is made up of eight items. Each item was scored from grade 1 to 4. The score of each item was projected to the MY radar chart, designed by us. It is noted that this method is useful in following the effect of(More)
We made an attempt to compare the complaints about sleep disturbance in the elderly based on the questionnaires using self-rating scales carried out in 1983 and 1996. It was noted that the score of awakening frequency from the course of sleep was the highest of all the items in men and women in both the 1983 and 1996 inquiries. The scores of insomnia nights(More)
A 17-year-old man was injured in a motorcycle accident, leading to a complex cerebral contusion and hepatic injury. Approximately one month after being discharged from the hospital, the patient experienced gradually progressive dyspnea on exertion. Chest computed tomography revealed severe upper tracheal stenosis; thus, emergency tracheotomy and subsequent(More)
Sleep EEG and nocturnal penile tumescence (NPT) were investigated in 6 healthy men during placebo and mianserin administration and after mianserin withdrawal. The results were assessed in a historical comparison with those previously obtained with clomipramine. With mianserin, REM sleep was suppressed slightly. However, the suppressive effect of mianserin(More)
BACKGROUND Recent studies have revealed a reduction in the skeletal muscle area in patients with advanced non-small cell lung cancer (NSCLC) after chemotherapy. EGFR and ALK tyrosine kinase inhibitor (TKI)-based therapies are less cytotoxic than chemotherapy, but differences in skeletal muscle mass between patients receiving EGFR and ALK TKI therapies and(More)
BACKGROUND Endobronchial ultrasonography using a guide sheath (EBUS-GS) is an increasingly common bronchoscopic technique, but currently, no methods have been established to quantitatively evaluate EBUS images of peripheral pulmonary lesions. OBJECTIVES The purpose of this study was to evaluate whether histogram data collected from EBUS-GS images can(More)
