The authors analyzed data from 15 patients with idiopathic dilated cardiomyopathy to evaluate the hemodynamic changes and left ventricular cineangiogram as compared with normal control. Mean right atrial pressure, right ventricular systolic pressure, mean pulmonary artery pressure and mean pulmonary wedge pressure were signigicantly elevated in patients with dilated cardiomyopathy. Left ventricular enddiastolic volume was increased in idiopathic dilated cardiomyopathy(139.9+/-58.73 ml/m2). Cardiac index, left ventricular ejection fraction and circumferential fiber shortening were significantly reduced in patients with dilated cardiomyopathy as compared with normal control(p<0.001). Hypokinetic, diffuse wall motion abnormalities of left ventricle were common in idiopathic dilated cardiomyopathy. A few cases of akinetic or dyskinetic segmental wall motion abnormalities were present. Left ventricular configurations in patients with idiopathic dilated cardiomyopathy were globe shape(53.4%) as compared with pear core shape(90%) of normal control. Associated mitral regurgitations in patients with idiopathic dilated cardiomyopathy confirmed by left ventricular cineangiogram were 53.3 percent. Mild to moderate mitral regurgitations were often present(46.6%).

Congenital synostosis of the proximal ends of the radius and ulna is a rare malformation which often completely prevents pronation and supination of the forearm. The evidence for a genetic etiology is provided by noting its presence in a Klinefelter's syndrome and its positive familial history. Two cases of congenital radioulnar synostosis occurred in brothers have been experienced and are to be reported with review of references.

Various kinds of spinal instrumentation have been developed for treatment of spinal disorders which are associated with instability. Recently, newly designed devices using pedicle screw were developed with advantages of short segment fixation and firm internal fixation. This is a retrospective clinical and roentgenographic study to evaluate the effectiveness of Cotrel 1. Of the 27 cases, spinal stenosis were 11, spondylolisthesis were 8, spondylolysis were 4, burst fracture were 2, metastatic bone tumor was 1, and failed back syndrome was 1 case. 2. Result of clinical evaluation by Hanley's criteria at last follow up were excellent in 7(27%), Good in 15(58% ), fair in 4(15%). (1 case of metastatic bone tumor was excluded). 3. In the cases of spondylolisthesis, we tried to reduce the displacement in 2 cases of Meyerding Grade II, and 1 case was reduced and 1 case was not reduced. In the cases of of Meyerding Grade I, no further displacement was developed. 4. The complications were observed in 10(37%)cases. A) Generalized complications were 2 cases of hematoma, 3 cases of superficial infection of wound, and 1 case of nerve root irritation. B) Failure in instrmentation were 1 case of screw breakage, 1 case of complete loss of fixation between screw and rod, and 2 cases of partial loss of fixation. 5. To prevent above mentioned complications in fixation of the instrument, the following factors are recommended: 1) Selection of the adequate length of rod. 2) Fixation of the additional implant such as security bolt when instability between screw and rod is predictable. 3) Selection of the closed head screw in the fixation of proximally sided screw if possible. 6. Cotrel-Dubousset instrument has many advantages such as rigid internal fixation, anatomical reduction, and good maintenance and also effective in reduction and maintenance of spondylolisthesis and in wide posterior decompression of spinal stenosis, but for prevention of some complications, precise use of instrument and good application of surgical technique will be needed.

With increasing tendency of incidence and interest for the late onset schzophrenia, concerns about whether this disorder is etiologically or phenomenogically distinctive entity or not have increased also. To clarify the disease entity of the late onset schzophrenia and the role of structural brain changes in its etiology, authors tried to prove following hypothesis : Are there any evidences of structural brain changes in the late-onset schizophrenia? ; If present, are they not different from those of the early-onset schizophrenia or progressive schizophrenia? ; And are they not different from those of senile dementia? Subjects were 6 patients with the late-onset schizophrenia, 6 patients with the early-onset schizophrenia, 6 patients with progressive schizophrenia, 6 patients with Alzheimer's dementia, and 6 controls. We measured regions of interest of the magnetic resonance images by computer assisted planimetry using the AutoCad and digitizer. Our study results may suggest that the third ventricular enlargement and a reversal of normal difference between left and right temporal lobe and left-right difference in posterior lateral ventricle are common brain pathology for all type of schizophrenia including the late onset schzophrenia. And also suggest that brain structural changes of the late onset schizophrenia are related with neurodevelopmental abnormality rather than degenerative change.

Vertigo mimicking labyrinthine lesions may have resulted from ischemic insult to the inner ear or the vestibular nerve and nucleus in the AICA infarction syndrome. A 56-year-old female was admitted to the emergency room with vertigo and hearing loss in right ear. On neurological examination, she had left beating jerky torsional and horizontal nystagmus with falling and past pointing to right side. Brain magnetic resonance images showed high signal intensity in anterolateral portion of inferior pons on T2- weighted images. Severe right facial palsy of peripheral type developed 24 hours after admission. Audiometry and electronystagmography documented absent auditory and vestibular function on the affected side. We argue that vertigo of the acute infarction in AICA territory can be involved the eight and seventh nerve root entry zoon and mimic labyrinthine lesions

The craniopharyngima has been known to be congenital origin and primary tumor of childhood. The craniopharyngioma may be found at all ages, though nearly one half in the first twenty years of life and equally in either sex. Important differences exist between younger and older patients. In children, signs of increased intracranial pressure, endocrine Abnormality and radiological calcification are common. In adults, mental disturbance becomes of increasing importance as well as remaining visual failure and endocrine disturbance. Because of slow growing rate of tumor in adult, subtotal excision is recommended. A 39-year-old male patient, suffering from agitation memory disturbance and almost total blindness, was diagnosed craniopharyngioma by neuroradiologic examinations. After surgical treatment, mental symptoms and visual acuity improved much more than before operation.

BACKGROUND: The potential adverse effects of ketamine in neurosurgical anesthesia have been well established. However, the effects of ketamine on intracranial pressure (ICP) and hemodynamics during general anesthesia remain unclear. The purpose of this study was to assess the effects of ketamine on hemodynamics and ICP in anesthetized, ventilated rabbits. METHODS: Thirty rabbits were divided into three groups: Group 1 (n=10) received 1 ml/kg normal saline iv; Group 2 (n=10) received 0.5 mg/kg ketamine iv; Group 3 (n=10) received 1.0 mg/kg ketamine iv. After induction with thiopental, anesthesia was maintained with isoflurane and nitrous oxide in oxygen. During controlled ventilation, ICP, mean arterial pressure (MAP), cerebral perfusion pressure (CPP) and heart rate (HR) were measured. The ICP was measured using Ladd ICP monitoring system. All variables were evaluated at baseline and for 30 min following ketamine. RESULTS: In group 1, ICP, MAP, CPP and HR were unchanged over the course of the study. In group 2, ICP, MAP and CPP were unchanged. HR increased at 1, 3 and 5 min (p<0.01), 10 and 20 min (p<0.05) after injection. In group 3, ICP, MAP and CPP increased at 1 and 3 min (p<0.01) after injection. HR increased at 1, 3 and 10 min (p<0.01), 5 min (p<0.05) after injection. CONCLUSIONS: These results suggest that 0.5 and 1.0 mg/kg of ketamine don't significantly affect the hemodynamics and ICP in anesthetized, mechanically ventilated rabbits.
