An assessment system for the prognosis of metastatic spine tumors was evaluated for 64 cases who had undergone surgery. Six parameters were employed in the assessment system: 1) the general condition, 2) the number of extraspinal bone metastases, 3) the number of metastases in the vertebral body, 4) metastases to the major internal organs (lungs, liver,(More)
PURPOSE We compared the negative chronotropic and inotropic effects of landiolol and esmolol, two clinically available short-acting beta1-blockers with high beta1-selectivity, using whole isolated rabbit heart preparations. METHODS Tachycardia was induced by continuous perfusion of 10(-7) M isoproterenol, and we used concentrations of landiolol or esmolol(More)
We studied somatosensory evoked potentials (SEPs) in 20 chickens with experimentally induced scoliosis after pinealectomy and in 100 patients with idiopathic scoliosis. We also studied 20 chickens without scoliosis and 20 healthy youngsters. In the chickens, SEPs after leg stimulation was significantly delayed in the scoliosis group compared to the(More)
Fifty-seven patients with low back pain and sciatica of various causes were reviewed with reference to problems associated with pedicle plate fixation of the lumbar spine. Eleven percent of patients had neurologic problems postoperatively and 3.5% (two patients) had severe sensory impairments. All patients had this complication in the early phases of the(More)
In patients undergoing spinal fusion and Cotrel-Dubousset instrumentation we recorded compound muscle action potentials (CMAP) from the lower limb and spinal somatosensory evoked potentials (SSEP) from the caudal epidural space after direct stimulation of rostral spinal cord via epidural electrodes. In three of 30 patients tested, the derotation maneuver(More)
The second cervical vertebra (C2) is in a pivotal position for the alignment and stability of the cervical vertebrae as a whole. Since its spinal canal is wider at the cranial and narrower at the caudal end, a dome-like excision of the inner side of the spinal canal from the caudal toward the cranial end results in the decompression of the lesion,(More)
UNLABELLED Hypothermia after induction of general anesthesia results largely from core-to-peripheral redistribution of body heat. Both central inhibition of tonic thermoregulatory vasoconstriction in arteriovenous shunts and anesthetic-induced arteriolar and venous dilation contribute to this redistribution. Ketamine, unique among anesthetics, increases(More)
BACKGROUND Reduced postoperative pain is considered one of the benefits of laparoscopic inguinal hernia repair (LHR). We investigated the need for intravenous flurbiprofen axetil (FA) before emergence from anesthesia in patients who had undergone LHR. METHODS Forty adult patients who were prepared for LHR were randomly divided into the FA group (FA 1 mg x(More)
In this study, the authors evaluated the effects of spine manipulations, similar to those used in scoliosis surgery, on the compound muscle action potential (CMAP) and spinal evoked potential (SEP) in 25 cats: a distraction maneuver was performed in ten, a rotation in five, and a combined (distraction and rotation) procedure in ten cats. Compound muscle(More)
There are many problems concerning management of giant cell tumors in the pelvis: diagnosis, surgical approach, adequacy of treatment, reconstruction, and prognosis. Of 58 cases of giant cell tumor of bone from 1962 to 1985, five cases arose in the pelvis, two in the ilium, two in the ischium, and one in the pubis. Surgical procedures included en bloc(More)
