BACKGROUND Radial access is the preferred route for cardiac catheterization; however, small radial arterial diameters can make complex procedures difficult. The assessment of radial artery diameters prior to intervention may be beneficial for the interventional cardiologist. Our aim was to measure the diameter of radial arteries in a study sample from our(More)
We examined the effects of a short-term low-calorie diet on the activity of the autonomic nervous system during stress tests in obese patients with hypertension by analysis of heart rate and blood pressure variability. Eighteen obese inpatients with essential hypertension were given a regular-calorie diet (1,600 kcal, NaCl 7 g) for 4 days, and then a(More)
We report a 42-year-old woman with severe motor and intellectual disabilities (SMID) who showed partial central diabetes insipidus during severe pneumonia. Serum sodium levels were previously within the upper normal range from 140 to 147 mEq/L. During pneumonia, however, serum sodium rose rapidly to reach 185 mEq/L. The daily urinary volume exceeded the(More)
A Japanese man who died at age 86 had been followed since the age of 58, when he presented with hypertension of 150/95 mmHg. The patient remained socially active until he died suddenly of a ruptured thoracic aortic aneurysm, although he experienced angina pectoris in August 1974, and myocardial infarction was identified on electrocardiography in October(More)
At the time of the first visit to our clinic, an electrocardiographic examination of a 73-year-old female patient revealed ventricular premature contractions (VPCs) with variable coupling intervals that were diagnosed as parasystole. Characteristically many of the parasystoles had no sinus contractions between two consecutive VPCs, which we referred to as(More)
We studied sympathetic skin response (SSR) to visual emotional stimuli in two children with attention deficit/hyperactivity disorder (AD/HD) and nine healthy controls, and correlated them with comorbid disorders. They were diagnosed as having conduct disorder at administration. Two years after interventions of medical care, counseling and education, they(More)
Paroxysmal kinesigenic choreoathetosis (PKC) is a rare and benign disorder with its onset in childhood. PKC generally improves with age, and its pathophysiology has not been revealed. We recorded both ictal and interictal SPECT in a 14-year-old girl with PKC. Ictal SPECT showed a significant decrease in blood flow in the caudate nucleus contralateral to the(More)
