Sixty six Colles' fracture were treated with radial slab or U-cast (sugar tong splint), from January 1982 through May 1984 at the Department of Orthopaedic Surgery of St. Mary Hospital. A prospective study was made and was evaluated under the subjective criteria of Gartland and Werley, and the objective criteria of Scheck. The results of this study were as follows: 1. All of 66 cases was closed fracture and the incidence was high in females who aged over 6thdecades. 2. In 43 cases of stable fracture, 18 (94.7 %) out of 19 cases treated with radial slab and 21 (87.5%) out of 24 cases treated with U-cast showed satisfactory result. 3. In 23 cases of unstable fracture, 6 (54.6%) out of 11 cases treated with radial slab and 9 (75%) out of 12 cases treated with U-cast showed satisfatory result. 4. As a result, we found that the result of the treatment with radial slab was superior to the U-cast for the stable Colles fracture, however, all of two methods were not staisfatory for the unstable Colles fracture although the U-cast group showed better result.

PURPOSE: To analyze the imaging features of brain abscess. MATERIALS AND METHODS: MR studies of nine patients with surgically verified brain abscess were retrospectively reviewed. RESULTS: The shape of abscesses were round(n=6), multilobulated(n=2) or triangular(n=1). All lesions were located in corticomedullary junction and extended into white matter. On gadolinium-DTPA enhanced images, smooth rim-like(n=6) or irregular thick enhancement(n=3) of abscess wall was noted. Budlike projection from the abscess capsule was found in 4 cases. The signal intensity of abscess capsule was either hyperintense (n=5) or isointense(n=4) relative to white matter on Tl-weighted images, and hypointense(n=6), isointense (n=2) or mixed hypo and isointense(n=l) on T2-weighted images. Satellite nodules were found in 2 cases. PNS inflammation(n=2), meningitis(n=1), ventriculitis(=2) and subdural empyema(n=1) were associated CONCLUSION: The MR features of brain abscess included characteristic intensity of abscess capsule, budlike projection from the abscess wall, moderate amount of peripheral edema, satellite nodules, and associated meningitis, ventriculitis or PNS infection. The morphology of abscess wall was not specific for the diagnosis of brain abscess.

Pleomorphic (undifferentated) carcinoma is a rare histologic type of carcinomas of the gallbladder and an atypical carcinoid is thought to be an intermediated type between carcinoid tumor and small cell carcinoma. Dense core "neurosecretory" granules can be found in the above mentioned tumors. We experienced a case of a double tumor of the gallbladder in a 51-year old male patient. Grossly, a large solid mass, about 5.0 cm in diameter, was found in the fundic portion and the neck portion also had a small 1.5 cm-sized polypoid mass. Microscopically, these lesions had features of pleomorphic carcinoma and atypical carcinoid, respectively. Immunohistochemically, they manifested reactivity for neuron specific enolase. Ultrastructural study revealed neurosecretory granules in the cytoplasms of tumor cells of the fundic and neck masses. Although light microscopic features of these tumor masses are quite different, we consider that these tumors represent a spectrum of neuroendocrine differentiation.

Adenocarcinoma of the urinary bladder, including urachal carcinoma, is a rare tumor with incidence in the range between 0.5% and 2.2% of all epithelial bladder neoplasms. Ten cases of adenocarcinoma of the urinary bladder(eight cases of primary adenocarcinoma and two cases of urachal carcinoma)are presented. We described the computed tomography(CT)appearances of adenocarcinoma of the urinary bladder and tried to find out the characteristic CT findings of urachal carcinoma. CT scan were evaluated for the location of the tumors, presence of calcification in the tumor, and the tumor extension. Seven tumors were located at the dome of the bladder(70%0, two were at lateral walls, and one was at anterior wall. Seven were single mass and three were multicentric masses in the bladder. Fine punctate calcifications scattered within the tumors were detected in four cases(40%); three of the eight, primary adenocarcinoma, and one of the two, urachal carcinoma. Two urachal carcinomas were characterized by midline position and predominantly extravesical growth along the urachus. Gross extravesical extension with distant metastasis were presented in seven cases(70%) at the time of initial diagnosis. CT may be useful in evaluating the adenocarcinoma of the urinary bladder and differentiating urachal carcinoma from bladder cancer.

Focal segmental glomerulosclerosis is the renal histopathologic lesion observed in 10% of children with idiopathic nephrotic syndrome. Complications include infection, thrombosis, hypocalcemia and adverse effect of steroid use. The incidence of thrombosis reported ranges from 10~40%. The pathogenesis are changes in coagulation system, decrease of Antithrombin III, increase platelet aggregability and steroid or diuretics use. These changes take place passively as a result of increased protein synthesis and urinary loss of low molecular weight protein. We experienced a case of cerebral infarction due to thrombosis associated with focal segmental glomerulosclerosis and steroid resistant nephrotic syndrome in a 11 year old male patient who had been hospitalized because of convulsion and semicoma. MRI showed an evolving infarct in the occipital lobe, decreased antithrombin III and increased factor VIII on coagulation factor assay. We hereby report a case of cerebral infarction due to thrombosis associated with focal segmental glomerulosclerosis and steroid resistant nephrotic syndrome with a brief review of related literature.

An endodermal sinus tumor is a malignant germ cell tumor that usually arises in the gonads, but on rare occasion occurs in extragonadal locations. Our case was that of a 3 year old girl who complained of a rapid growing orbital mass. On histologic examination it revealed the typical picture of an endodermal sinus tumor and it also disclosed a positive reaction for alphafetoprotein using an immunoperoxidase technique. An orbital exenteration was performed followed by chemotheraphy, but the patient died 5 months after the onset of the disease.

PURPOSE: To evaluate the usefulness of percutaneous catheter drainage (PCD) in patients who have abdominal abscesses or fluid collections. MATERIALS AND METHODS: We performed PCD for 165 abscesses and fluid collections in 148 patients. The follow-up periods in these patients ranged from 15 days to 42 months (mean, 274 days). The lesion sites were subphrenic space in 46 cases, liver in 33, perihepatic space in 20, pancreas or peirpancreatic space in 14, pelvic cavity in 13, and retroperitoneum in 13. We evaluated the success, failure, and recurrence rates, the causes of failure or recurrence, the mean duration of drainage, and the complications of PCD. RESULTS: Of the 165 cases, one hundred-fifty nine(96.5%) were successfully cured, Although a partial success could be achieved, 2(1.2%) cases were failed and 4(2.4%) were recurred. Multiloculation or fistula formation were the main causes of the unsullessful cases. The duration of drainage rainged from 2 to 605 days (mean, 1 days). Complications occured in 12 cases(7%) during or after procedures, which included fever and chill in 7, transgression of pleura in 2, bowel perforation in 2, and bleeding through catheter in 1. CONCLUSION: PCD is an effective and safe method for various abdominal abscesses or fluid collections.

8.Acute Effect of Methylprednisolone in Experimental Spinal Cord Injury.
Journal of Korean Neurosurgical Society 1983;12(4):521-528
It is the purpose of this study to determine the benificial effect of treatment with methylprednisolone on the enhancement of Na+, K+-ATPase activity and the increased ATP level during the 4 hours after a 400gm-cm injury to the spinal cord of cat. These results demonstrate that high dose (30mg/kg) of methylprednisolone can benificially enhance the activity of neuronal Na+, K+-ATPase during the first 4 hour after spinal cord injury. But the enhancement of this enzyme activity is not significantly increased with mega dose (60mg/kg) of methylprednisolone. Tissue level of ATP in the high dose-treated cat at 1 hour after trauma was significantly elevated, but those in high dose-treated cat at 4 hour and the 1 and 4 hours with mega dose-treated groups were not significantly increased. The protective effects of methylprednisolone in experimental spinal cord trauma are the enhancement of Na+, K+-ATPase, inhibition of the free-radical reaction and the lipid peroxidation, the increment of neuronal activity and ATP utilization. High dose(30mg/kg) of methylprednisolone is required in order to produce the acute effect in the early phase experimental spinal cord injury.

BACKGROUND: Laryngoscopy and tracheal intubation for general anesthesia are potent stimuli to the cardiovascular system due to sympathetic stimulation. The aim of this study was to compare the hemodynamic responses with different administration routes of lidocaine on blood pressure and heart rate changes associated with tracheal intubation. METHODS: Sixty patients were randomly assigned to spray group (Group 1, n=20) received 10% lidocaine 1.5 mg/kg spray to intratracheally immediately before tracheal intubation, IV group (Group 2, n=20) received 2% lidocaine 1.5 mg/kg intravenously before 90 sec tracheal intubation and control group (Group 3, n=20). Anesthesia was induced with thiopental 5 mg/kg IV, vecuronium 0.1 mg/kg and 50% N2O-O2- 2vol % enflurane. After 5 minutes, tracheal intubation was performed. Mean arterial pressure and heart rate were measured at preintubation and immediately postintubation, 1, 3, 5 mins after tracheal intubation. RESULTS:The differences of mean arterial pressure which were measured at preintubation and immediately postintubation and 1 minute after intubation in group 1 were significantly lower than those in other group (p<0.05). The differences of heart rate which measured at preintubation and 1 minute after intubation were lower than those in group 3 (p<0.05). CONCLUSIONS: For the suppression of sympathetic stimulation following tracheal intubation, 10% lidocaine spray to the laryngotrachea is an effective method to suppress cardiovascular response.

Congenital mesoblastic nephroma(CMN) is an important differential diagnosis of a renal mass occurring in the newborn or in early childhood. It was first described by Bolande as a separate disease entity distinct form Wilms' tumor. In 1974, Beckwith has predicted that this tumor has a pathologic spectrum with classic congenital mesoblastic nephroma at one extreme, unequivocally mallignant spindle cell sarcomas at the other, and intermediate "gray zone" lesions of indeterminate biologic significanse. In 1986, Joshi has described "atypical mesoblastic nephroma" as a potentially aggressive variant of CMN, which shows atypical gross and microscopic features such as hemorrhage, necrosis, high cellularity, and mitotic index. We report of a case of atypical mesoblastic nephroma presenting in a 38 days-old male infant. Grossly, the tumor involved the upper and midportion of the left kidney. On section, the cut surface was fleshy, grayish-white, and homogeneous. Microscopically, the tumorshowed high degree of cellularity and arrangement of fusiform cells in sheets and vague interlacing bundles. The individual tumor cells showed fusiform to oval nuclei, indistinct scanty pale-eosinophilic cytoplasm and many mitotic figures.
