Forty-six patients (fifty hips) underwent revisions of a total hip arthroplasty that had failed but was not associated with infection, Three of these patients had a third revision. The mean length of follow-up was approximately two years. Thirty patients reported that their condition was improved. On final roentgenographic examination showed, two loosening of the acetabular components and five of the femoral components in which there was one sympto matic loosening (moderate severe pain and probable roentgengraphic loosening) noted. The extralong stems are not necessary in all revision cases, cortical defects at the tip of standard stem obviously should require bypass the stress riser with a longer stem. If the stability can be achieved with host bone, Revision may be carried out with a relatively short stem. Significant postoperative complications as subsidence and progressive loosening were noted in seven out of the forty-six patients. We consider that extensive porocoated cementless stem or standard flute stem seem to be a better outcome in revision arthroplasty.

Cell-mediated immunity frequently becomes impaired after major trauma. To investigate the immune response of the head injury, the authors measured the level of the serum neopterin, which represents the index of macrophage activation, in 53 head-injured patients. In the injured group the serum neopterin level was 5.4+/-3.1 nmol/l and slightly higher than that of the normal control group, 4.4+/-1.0 nmol/1. In the group of the patients with the Glasgow Coma Scale(GCS) 3-9, the level was significantly higher than the group GCS 10-15. The differences were not significantly related to the age or the presence of intracranial hematoma. It is conceivable that head injury will change the patient's immune response and it may be influenced by neural control.

Several different methods of posterior wiring and fusion have been advocated for treatment of the odontoid process fractures, regardless of direction of displacement. Between 1983 and 190, 8 cases of type II odontoid process fracture underwent posterior wiring and fusion at Kyungpook National University Hospital. Among them, three cases were posteriorly displaced fractures. For these three cases, the authors modified wiring method and applied acrylic resin. The authors thought this procedure is not complex and a good method for posteriorly displaced type II fractures in which conventional posterior wiring may actually create a tration effect that further displaces the fractured odontoid into the spinal canal.

Of the 68 cervical spondyltic patients showing symptoms of radiculomyelopathy, assessments were made on 29 patients who underwent neural decompressive surgery with cervical laminectomy through posterior approach for the results of surgery. Analyses were also made on the anterior-posterior diameters of cervical canal on the plain film of cervical spine. The mean values of anterior-posterior diameters measured on the levels of cervical C3-7 were 16.5+/-1.83 mm in the normal adult and 7.3+/-1.08 mm in the cervical spondylotic patients with radiculomyelopathy, which is far narrower than that of the normal. In cervical spondylotic patients, the anterior-posterior diameters of directly upper and lower parts of the lesions were 11.9+/-1.20 mm and 12.1+/-1.61 mm respectively, also much narrower mean values than those of the normal control group. The results of the 29 patients who received cervical laminectomy by posterior approach were much improved for 51.7% and improved for 44.8%.

Among 51 intractanial AVM patients, 30 patients(58.8%) with AVM supplied mainly with PCA were studied for the relationship with feeding vessels, location and the size of AVM in connection with hemorrhage and also results in 20 surgical patients were analyzed. On cerebral angiogram, 56.7% accounted for AVM supplied only by PCA, 16.7% together with MCA and 26.6% with MCA and ACA. By location, 36.7% were for subcortical AVM and 63.3% were for deeply located paraventricular. 53.3% were large AVM and of them, 6.5% bleeded 30.0% accounted for small AVM, of which 88.9% bleeded. The total bleeding rate was high at 73.3%. Complete removal by surgery was available for 90.0%, and post operative improvement was at 75.0% with a mortality rate of 10.0%. 50.0% showed disappearance of seizure following total removal and 33.3% improved. 5.0%, however, had seizure for the first time following the surgery.

PURPOSE: To evaluate the radiologic findings of carotid-vertebrobasilar anastomosis and associated anomalies. MATERIALS AND METHODS: Thirteen patients with fourteen cases of carotid-vertebrobasilar anastomosis collectedfrom January 1992 to December 1997 were reviewed. Clinical diagnosis refered for cerebral angiography werecerebral infarction(n=3), intracranial hemorrhage(n=2), subarachnoid hemorrhage(n=1), brain tumor(n=3),arteriovenous malformation(n=3) and trigeminal neuralgia(n=1). Cerebral angiograms and clinical symptoms wereretrospectively analyzed. RESULTS: The fourteen carotid-vertebrobasilar anastomsis consisted of eleven cases ofpersistent trigeminal artery and three cases of type I proatantal intersegmental artery. Persistent trigeminalarteries were associated with anterior communicating artery aneurysm(n=1), posterior fossa arteriovenousmalformation(n=2) and persistent trigeminal artery variant(n=5). Type I proatantal intersegmental arteries wereassociated with hypoplastic vertebral arteries(n=2) : only proximal segment in one, and proximal and distalsegments in one case. Only one patient had clinical symptom related to the carotid-vertebrobasilar anastomosiswhich was trigeminal neuralgia. CONCLUSION: Knowledge of the anatomical and radiologic findings ofcarotid-vertebrobasilar anastomosis and associated anomalies will aid in the accurate diagnosis of neurovasculardisease and prevent possible complications during surgical and interventional procedures.

A daily count of air borne pollen was done within the city limits of Seoul, Korea for a period of two years (1984-1985) using Durham's Gravity Sampling Device. Two major pollen seasons, March through May, and the month of September, were easily distinguishable. The concentration of the different types of pollen as well as all of the pollens combined varied similarly both years to a significant degree. The pollen types found in the greatest numbers were Alnus (March), Populus (April), Quercus (April-May), Pinus(May), grasses (September), and weeds (September). The main weed pollens detected in September, sagebrush, ragweed and Japanese hop would also be considered to be important allergenic pollens of respiratory allergy in Korea. The results of the survey are discussed in the light of especially relevant published literature.

Among 202 aneurysmal patients with SAH who were admitted to Kyungpook National University Hospital from Jan. 1984 through Jan. 1988, the incidence of ventricular dilatation confirmed by postoperative follow-up brain CT scannings was 32.2%(65 cases). And 33 cases(19.3%) was in mild ventricular dilatation, 9 cases(4.5%) was in moderate and 23 cases(11.4%) in severe who needed the shunting procedure were analysed. The incidence of ventricular dilatation to the site of aneurysm was highest in A-com A. aneurysm(42.2%), followed by P-com A. aneurysm(36.4%) and MCA aneurysm(11.3%). The incidence of ventricular dilatation and the need for shunting was higher in multiple bleeding patients than the single. The good risk patients had meaningfully lower incidence of ventricular dilatation than the poor risk group. In the delayed surgical group showed significantly more numbers of ventricular dilatation needing the shunt than the cases in early group.

Neurofibromas are benign, slow-growing nerve sheath tumors of the peripheral nervous system, arising from Schwann cells, and classically associated with neurofibromatosis type 1 (Nf1, von Recklinghausen's disease). They occur rarely in the gastrointestinal tract as isolated neoplasms, outside the classical clinical feature of neurofibromatosis. We herein present an isolated colonic neurofibroma without any systemic signs of neurofibromatosis. A 59-year-old female came to our hospital for constipation. On physical examination, general appearance showed no definite skin lesions. A subepithelial tumor measuring 0.8 cm was detected at the distal descending colon on colonoscopy. The lesion was removed completely by endoscopic resection. Microscopic examination showed proliferation of spindle cells in the mucosa and infiltration of inflammatory cells. Immunohistochemical staining was positive for S-100 protein. The above morphological and immunohistochemical characteristics were consistent with a diagnosis of a solitary neurofibroma of the sigmoid colon.
