A sarcomatoid carcinoma of the urinary system is a rare malignant tumor, composed of both epithelial and stromal cells, is regarded as a similar disease entity to a carcinosarcoma. In Korea, only 1 case of primary sarcomatoid carcinoma and 4 cases of carcinosarcoma involving the bladder have been reported, but to date, no case of primary sarcomatoid carcinoma involving the renal pelvis has been reported. Recently, we experienced a case of sarcomatoid carcinoma involving the right renal pelvis in a 67-year-old male patient with intermittent gross hematuria. A CT scan demonstrated a 5x4cm sized mass in the right renal pelvis. Under the diagnosis of a right renal pelvic tumor, a right nephroureterectomy, with bladder cuff excision, was performed. The tumor was composed mostly of pleomorphic spindle cells, and in the peripheral part of the tumor and renal pelvis, a high grade transitional cell carcinoma and adenocarcinoma was also found. The tumor was pathologically confirmed as a primary sarcomatoid carcinoma of the renal pelvis.
자발성 뇌실질내출혈의 임상소견과 CT 소견에 대한 고찰

An analysis has been made of the clinical obrservation and computed tomographic finding in 40 cases of spontaneous intracerebral hemorrhage which were confirmed by SOMATOM Ⅱ. computed tomographic scanner. Computed tomographic scan are very helpful in the diagnosis, prognosis and treatmant of spontaneous intracerebral hemorrhage. Location of spontaneous intracerebral hemorrhage has been of more greater value in evaluation of progrosis than any other factors of CT scan finding. Surgical intervention were performed in 15 cases and rest 25 cases were managed conservatively. The result of operative treatment were better than those of medical care.

Computed tomography(CT) has enabled early recognition and treatment of focal injuries in patients with head trauma. However, CT has been less beneficial in identifying diffuse brain injury(DBI). The authors have analyzed retrospectively, a series of 132 patients with DBI observed for 2 years from Aug. 1986 to Jul. 1988 to evaluate the significance of the factors affectiong ourcome. Eighty-three patients were selected as being compatible with moderate and severe diffuse axonal injury(DAI) classified by Gennarelli, defined by coma without a CT lesion that is an obvious cause and coma greater than 24 hr with or without decerebration. The results are summarized as follows: 1) The 38(45.7%) out of 83 patients were found below age of 20, but there was no statistical significance between age distribution and outcome. 2) In case of initial Glasgow coma scale(GCS) of 7 or 8, 32(86.5%) out of 37 patients revealed good outcome, but 18(90%) of 20 patients with a score of 3 or 4 revealed poor outcome(p<0.001). 3) With regard to brain swelling in CT, there was significant statistical difference to outcome(p<0.05). 4) Small hemorrhages on corpus callosum, basal ganglia, basal cistern, peritentorial, lateral ventricle that is characteristic CT findings for DAI were showed 58(70%) out of cases. It might be concluded that initial GCS, brain swelling and small hemorrhages in CT were significant factors affecting outcome in DAI.

The ultimate purpose of treatment in hypertensive intracerebral hematoma(HICH) is effective evacuation of the hematoma with minimal damage to normal brain tissue and prevention of increasing intracranial pressure and progression of an ICH into neighbouring tissue. According to this viewpoint, stereotactic surgery in patients of HICH is recent trend for its safety and precision. An analysis of 50 consecutive patients from Jun. 1988 to Mar. 1989 undergoing stereotactic surgery with urkinase irrigation in HICH was performed. We excluded the HICH below 15cc of volume, poor clinical grade as coma with herniation sign, intraventricular hemorrhages only, infratentorial hematoma and atypical spontaneous intracerebral hematomas as angiographically verified aneurysms, AVM and Moyamoya diseases. Procedures were accomplished utilizing the CT-guided BRW stereotactic frame, then urokinase irrigation was done every 6 hours through a stereotactically inserted catheter until a sufficient volume was drained, and then the patient was checked by a follow-up CT scan. The results were analysed as follows: The incidence was highest in 6th decade with male predominence(62%). Mean dose of urokinase was 6000 IU ×18.73(4.6 days). The statistical analysis of the factors affecting outcome showed that initial neurological grading was highly significant (P<0.001); volume of hematoma was significant also (p<0.05). Associated intraventricular hemorrhage especially ventricular tamponade in HICH was highly poor prognostic factor. Overall good result was 54% and mortality rate was 12% All computations were performed by means of the commonly used SPSS statistical package.

Video data are retrieved and stored in various compressed forms according to their characteristics. In this paper, we present a generic data model that captures the structure of a video document and that provides a means for indexing a video stream. Using this model, we design and implement CVIMS (the MPEG-2 Compressed Video Information Management System) to store and retrieve video documents. CVIMS extracts I-frames from MPEG-2 files, selects key-frames from the I-frames, and stores in database the index information such as thumbnails, captions, and picture descriptors of the key-frames. And also, CVIMS retrieves MPEG-2 video data using the thumbnails of key-frames and various labels of queries.
