Idiopathic syringomyelia, which is not associated with any definite pathogenic lesions, has been treated mainly by shunting of the syrinx and rarely by craniocervical decompression. The authors report four cases of syringomyelia thought to be idiopathic syringomyelia but treated by craniocervical decompression with favorable results. Syringomyelia was(More)
A case is reported in which a human chorionic gonadotropin (HCG-)-producing ectopic pinealoma was found in a 5-year-old girl with precocious puberty. Physical examination revealed abnormal breast enlargement. Endocrinological study disclosed a high plasma HCG concentration of 1192 ng/ml with a normal follicular stimulating hormone (FSH) level. The HCG(More)
A 54-year-old female presented with subarachnoid hemorrhage due to rupture of a small middle cerebral artery aneurysm, found to be thrombosed at surgery and not visualized on the preoperative angiograms. One major branch of the middle cerebral artery was found to be occluded near the trifurcation. The lumen of the branch proximal to the occlusion had(More)
We have performed tissue culture of pituitary adenomas (5 acromegalies, 7 non-acromegalies) and measured GH, PRL, LH and FSH in the media of tissue culture by radioimmunoassay (RIA) for 30-40 days. In addition, GH, PRL, LH and FSH were measured in the plasma and tumor tissue by RIA. GH concentration in the culture media was markedly high in all cases with(More)
INTRODUCTION The Suwa Onbashira Festival is held every six years and draws approximately one million spectators from across Japan. Men ride the Onbashira pillars (logs) down steep slopes. At each festival, several people are crushed under the heavy log. During the 2004 festival, for the first time, a medical care system that coordinated a medical team, an(More)
AIM To examine the methods used to estimate nurse staffing levels in acute care settings with Diagnosis Related Groups, which in Japan are called the Diagnosis Procedure Combination (DPC). METHODS For estimating staffing requirements, the study used four DPC groups: (1) acute or recurrent myocardial infarction (AMI) with stenting, (2) angina pectoris with(More)
HCG-producing ectopic pinealoma of two cell pattern type was demonstrated in a 5-year old girl who presented precocious puberty and bilateral choked discs. The tumor was localized at the anterior third ventricle and suprasellar region. Endocrinological findings are as following: Plasma basal LH was markedly elevated to 306 mIU/ml and HCG was elevated to(More)
For the past one year, 13 patients were studied 20 times with cineradiography to diagnose abnormal spine motion, which was quite informative compared to usual plain spine X-ray pictures. The direct radiation dosis was only 2.35 rem/min on taking cineradiography at the speed of 60 frames/sec. The camera used was Cardoskop-U and the X-ray generator was(More)
