Concurrent use of instrumentation has been shown to increase fusion rates and satisfactory results for surgical treatment of the lumbar stenosis. The objectives of the present study were to evaluate clinically and radiologically two groups of lumbar stenosis who were surgically treated with pedicular screw fixation system and posterior lumbar interbody or posterolateral autogenous bone graft following complete posterior decompression. One group was degenerative type and the other group was spondylolisthetic type spinal stenosis. We analyzed the results of 39 cases of lumbar stenosis who underwent pedicular screw and rod fixation system and posterior lumbar interbody or posterolateral autogenous iliac bone fusion following complete posterior decompressive operation during the period from May 1988 to December 1992. There were 27cases of degenerative type and 12 cases of spondylolisthetic type lumbar stenosis. The were 25 women and 14 men. Their age was ranged 20 to 76 years old with an average of 51.7 years old. The follow up period was the interval from 18 months to 6 years with an average of 3.2 years. The radiologic union rate was average 94.9% and 96.3%(26cases) in degenerative spinal stenosis and 91.7%(11 cases) in spondylolisthetic spinal stenosis. The clinical success rate was average 92.3%(36 cases), 88.9%(24 cases) in degenerative spinal stenosis and 100%(12 cases) in spondylolisthetic spinal stenosis. The patients with spondylolytic spinal stenosis showed better result in their life than the patient with degenerative spinal stenosis.

Hemangiopericytoma was first described by Stout & Murray in 1942 and was an uncommon soft tissue tumor thought to be derived from vascular pericytes. Approximately 10-15% of the cases occur in children have a propensity to develop in the region of head, neck and lower extremities. We experienced a case of congenital hemangiopericytoma of small bowel in a male neonate who showed vomiting and abdorninal distension. We reported a case of congenital hemangiopericytoma of small bowel with brief review of related literature.

Traumatic intracranial lesion has been one of the most frequent and serous problem in neurosurgical pathology. CT made it possible to get prompt diagnosis and surgical intervention of intracranial lesions by its safety, fastiness and accuracy. Computed tomographic scan was carried out on 1309 cases at Soonchunhyang Chunan Hospitalfor 15 months from Oct. 1983 to Dec. 1984. We have reviewed the computed tomographic scans of 264 patients whichshowed traumatic intracranial lesion. The results were as follows: 1. Head trauma was the most frequentlydiagnosed disase using computed tomographic scans(57.8%), and among 264 cases the most frequent mode of injury wastraffic accident (73.9%). 2. Skull fracture was accompained in frequency of 69.7% and it was detected in CT in38.6%: depression fractue was more easily detected in 81%. 3. Countercoup lesion(9.5%) was usually accompained with temporal and occipital fracture, and it appeared in lower incidence among pediatric group. 4. Intracranial lesions of all 264 cases were generalized cerebral swelling(24.6%), subdural hematoma(22.3%), epiduralhematoma(20.8%), intracerebral hematoma(6.1%), and subarachnoid hemorrhage(3.0%). 5. The shape of hematoma wasusually biconvex(92.7%) in acute epidural hematoma and cresentic(100%) in acute subdural hematoma, but the morechronic the cases became, they showed planoconvex and biconvex shapes. 6. Extra-axial hematoma was getting decreased in density as time gone by. 7. Hematoma density was not in direct proportion to serum hemoglobin levelas single factor.

DSA(Digital Subtractin Angiography) is a valuable diagnostic imaging method in many clinical fields, includingranal-related conditons. Sixty four renal DSA examinations were performed in 59 patients with renal-relateddiseases from Jan. 1984 to Dec. 1985. Summary of these were as follows: 1. Intraarterial (IA)-DSA is performed in6 cases, intravenous(IV)-DSA in 58 cases. In 58 Examinations of IV-DSA, diagnostic image quality is obtained in 51cases(88%). 2. In investigations of a possible renovascular etiology of hypertension, IV-DSA,is a safe, sensitiveand accurate method. On screening for evaluation of renovascular hypertension, RSP should be replaced with IV-DSA,because IV-DSA is moe sensitive and accurate and can detect not only anatomic change of renal arttery but alsofunctional hemodynamic change. 3. IV-DSA is valuable in diseases with morphologic changes of vessels. Incharacterization of a known renal mass, and evaluation of hematuria, suspected aneurym and renal trauma, IV-DSA isvery useful diagnostic imaging modality. 4. In evaluation of potential renal donors, IV-DSA is an accurate andsafe method with 82.4% of accuracy. IV-DSA also is useful in follow-up of allograft recipients. 5. Ininvestigation of diabetic nephropathy, glomerulonephritis, pyelonephritis, IV-DSA is little helpful. 6. Theadvantages of DSA are well known, particularly post-procedure process using computer programs is helpful forobtaining informations of hemodynamic change or time-sequence-curve of density etc. More technical improvementwith this modality is required for improvement of the image quality and resolution. And more accumulation ofclinical experience is required in order to increase the diagnostic accuracy.

PURPOSE: The purpose of this study is to analyze the CT features of the cystic masses in the neck and to review differential diagnosis. MATERIALS AND METHODS: We retrospectively reviewed and analyzed the CT findings of 22 histopathologically proved, cystic neck masses in regard to the location in fascial plane and relationship with adjacent organ. RESULTS: Of 22 cases, ten congenital cysts two ranulas, seven inflammatory lesions, and three solid tumors were includded. Ten congenital cystic masses were located in typical locations as branchial cleft cyst(5) in mandibular angle, thyroglossal duct cyst(3) in visceral space embeded within the strap muscles, cystic hygroma(1) and cavernous hemangioma(1) in posterior cervical space with insinuating appearance. Two cases of ranula included one simple ranula localized in sublingual space and a plunging ranula extending to adjacent submandibular space. Seven cases of inflammatory lesions were characterized by multispatial locations and good contrast-enhancement of walls and adjacent tissue. Solid masses of low density mimicking cyst were two pleomorphic adenomas of submandibular gland and one neurilemmoma. CONCLUSION: It is considered that thorough analysis of the CT findings with attention to typical location, CT appearance, and the relationship with the adjacent structures usually leads to the correct diagnosis.

In order to evaluate the confounding factors of neurobehavioral tests and the neurobehavioral effects in the workers exposed to organic solvents, NCTB was carried out on 100 workers. 46 workers had never been exposed to neurotoxic substances, and the others were being exposed to the solvents, mainly toluene. Simple reaction time, digit symbol, Santa Ana dexterity test and persuit aiming were different with age in non exposure group. Simple reaction time was carried out well in males, and digit symbol and persuit aiming were in females. There was no difference at educational level when the subject was educated over 12 years. Santa Ana dexterity and Benton visual test differed according to exposure level to toluene, however simple reaction time didn't. The acute neurotoxic effect was not excluded in this study. But, NCTB could be used to evaluate and prevent neurobehavioral changes in workers exposed to neurotoxic solvents in Korea.

BACKGROUND: The incidence of Cutaneous malignant tumors has increased recently and they have varied in their developing patterns according to social and environmental influences. However, we have little clinical data about the cutaneous malignant tumors in the Chonnam provinee. OBJECTIVE: Our purpose was to analyze the clinical characteristics of cutaneous malignant tumors observed in the Chonnam province and to compare them with the data previously reported in Korea. METHOD: We clinically analyzed 427 cases of cutaneous malignant tumors during a 10 year period betwecn January 1987 and Oetober 1996, at the Department of Dermatology, Chonnam Univemity Hospital in Kwangju. RESULTS: 1. The average armual incidence of cutaneous malignant tumors among the total number of outpatients was 1.00+/- 0.25%. The incidence tended to increase with time from 0.90+/-0.29% in the first 5 year-period to 1.15+/-0.09% in the late 5 year-period. The increasing rate was most pronmient in basal cell carcinoma. 2. The most common tumor in the 427 patients with malignant tumor was basal cell carcinoma (52.5%), followed by squamous cell carcinoma (19.9%), malignant melanoma (13.3%), metastatic carcinoma (3.7%), malignant lymphoma (2.3%). 3. The mean age of onset was 60.7+/-16.0 years old (male; 59.6+/-15.0, female; 61.9+/-17.1) in the in the group as a whole; 63.9 in BCC, 63.3 in SCC and 55.8 in malignant melanoma. The ratio of men to women was 1.14:l. 4. The most common site of a11 malignant tumors was the head and neck (64.6%), where 89.3% of BCC, 58.8% of SCC, and 15.8% of malignant melanoma developed. The next common site was the lower exlremities and feet (15.7%) followed by the trunk (7,7%), and upper extremities and hands (7.3%).

We report two cases of cellulitis on the saphenous venectomy scar which developed after a coronary artery bypass graft(CABG). A 68-year-old male and a 62-year-old female developed acute cellulitis in the saphenous vein donor extremity after CABG. The repeated bacterial cultures were negative in both cases. However, onychomycosis was confirmed in one patient. The intervals between CABG and the initial bout of cellulitis in the male and female patient were 10 and 22 months, respectively. Although the exact pathogenesis remains obscure, factors such as direct bacterial infection, hypersensitivity to streptococcal exotoxins, a local compromise of lymphatic and venous drainage, and fungal infection might have contributed to the development of cellulitis in these patients.

The authors experienced a case of the monomorphic adenoma of lacrimal gland. Monomorphic adenoma is an extremely rare salivary gland tumor. A fifty eight year old Korean female was admitted to our Dept. of Ophthalmology because of multiple small nodular masses on her right upper eyelid and a large hard solitary mass in the supraorbital area since one year ago. On B-scan ultrasonogtaphy, round echo-free zone was detected in the superiortemporal orbit. Well defined hyperdense, enhanced round extraconal mass in the superiororbital area was detected by orbital CT scan. Two large well encapsulated, dark brown colored masses were extracted by supraorbital approach and lateral orbitotomy under general anesthesia. After removal of the masses, histopathologic examination confirmed the lacrimal monomorphic adenoma.
