PURPOSE: The Swedish Interactive Thresholding Algorithm (SITA) strategies is a new diagnostic tool of Humphrey automatic perimetry and has been reported to reduce testing time without loss of useful diagnostic information. To test the usefulness of this new diagnostic method, we compared the SITA and full threshold diagnostic method, which had been used previously. METHODS: Forty six patients (46 eyes) who were followed up for glucoma or ocular hypertension were in this study. Autoperimetry was performed using both SITA and full threshold strategies. RESULTS: The SITA showed shorter testing time (7.74+/-1.25 min) than the full threshold (14.4+2.43 min). There were significant differences between the full threshold MD (-8.06+8.11 dB) and SITA MD (-7.45 +/-8.32 dB), as well as full threshold PSD (4.47+/-2.50 dB) and SITA PSD (3.67+/-2.56 dB), when compared with data of greater than -12 dB MD respectively(p<0.05). Two cases showed changed diagnosis in GHT. CONCLUSIONS: SITA is a good test method with short test time. However, changing from full threshold to the SITA method should be reconsidered due to variation in the amount of field defect depending on the damage progression and the possibility of changes in diagnosis.

A lipomatous tumor originating in the uterus is a rare benign neoplasm, and most reported cases have been of the mixed type. Authenticated cases of pure lipomas of the uterus are extremely rare. We report one such case in which the findings of magnetic resonance imaging provided the basis for preoperative diagnosis.

PURPOSE: To evaluate the usefulness in diagnosing the gallbladder perforation MATERIALS AND METHODS: CT scans of surgically proved 11 cases of gallbladder perforation were retrospectively reviewed. CT findings analyzed were iuminal diameter of GB, GB wall thickness and configuration, presence or absence of fluid collection in the pericholecystic or intraperitoneal space, and observation of pericholecystic anatomic structures. All patients underwent cholecystectomy, and surgical findings were also compared. RESULTS: The GB was distended in 6 cases(55% with a range of 4.0-7.5cm, mean :5.2cm). GB wall was thickened in most cases(9/11,82%) with homogeneous(n=7) or inhomogeneous(n=2) enhancement. At the sites of perforation, focal defect or contour bulging was seen in the GB wall in 3 cases. in 2 cases with gangrene, GB wall showed loss of normal contour with mottled contrast enhancement. Pericholecystic or intraperitoneal fluid co11ection was noted in 9 cases(82%), especially in the region of perforation. In all cases, there was evidence of diffuse infiltration in the pericholecystic space, omenturn or mesentery. Other findings included cholecy-stoenteric fistula in 1 case, and intrahepatic or intraperitoneal abscess formation in 2 cases. CONCLUSION: CT is useful in correct diagnosis of gallbladder perforation.

To evaluate the effects of the preoperative chemoradiation therapy(CRT) for rectal cancer. 31 rectal cancer patients received preoperative CRT. A total 3060cGy of radiation was given in 3 weeks, 180cGy for a fraction. 425mg/m2/day of 5-FU and 20mg/m2/day of leucovorin were continuously infused in the first 5 days of the preoperative radiation therapy. A IV injection of Mitomycin C 10mg/m2 was given on the first day. A digital rectal examination, endoscopy with biopsy, barium enema, chest X-ray, hepatobiliary ultrasonography & IV bolus CT were done before and after CRT. Clinically, 19 patients(61.3%) and pathologically, 16 patients(51.6%) showed reduced tumor size. In 7 patients (22.6%), there was no residual tumor in the pathologic specimen. Digital rectal examination was possible in 23 patients. 16(69.5%) of them had a decrease in height of ulcer margin on digital rectal examination. Seven of the fifteen patients showed decreased perirectal fat tissue infiltration. There was no severe toxicity which might delay the curative surgery. In conclusion, preoperative chemoradiation therapy in rectal cancer was very effective in reducing tumor size and perirectal fat tissue infiltration without considerable toxicity.

PURPOSE: To assess changes in MR signal intensity in the pars interarticularis and adjacent structures in pa-tients with lumbar spondylolysis. MATERIALS AND METHODS: The MR images of 36 patients with lumbar spondylolysis, confirmed by plain radiographs, were retrospectively analyzed. Using a 1.0T unit, we evaluated the signal intensity of a total of 216 parts interarticulares and adjacent structures from L3 to L5, as seen on sagittal images, and differences between areas with and without spondylolysis. The signal intensity of T1-and T2-weighted images was graded 0 (more hypointense than spinal body), 1(as isointense as spinal body), 2(more hyperintense than spinal body and more hypointense than epidural fat), or 3(as isointense as epidural fat). Signal intensity change in end-plates and degree of spondylolisthesis were analyzed, and the relationship between these factors was deter-mined. RESULTS: Spondylolysis was noted at L5 in 61 cases, at L4 in 22, and of L3 in no case. In three cases spondylolysis was unilateral, and in the remainder it was bilateral. The degree of signal intensity was the same on T1- and T2-weighted images, and no case was grade 0. Eighty-six of 133 areas without spondylolysis were grade 1, 43 were grade 2, and four were grade 3. In 42 of 47 cases, signal intensity change was localized at pedicles. Among 83 areas with spondylolysis, on the other hand, nine were grade 1, 48 were grade 2, and 26 were grade 3. Signal intensity change was most commonly observed at the pars interarticularis, pedicle, and lamina (50/74) (p<0.001). Signal intensity change at the pars interarticularis and adjacent structures was accompanied in most cases by degenerative endplate change(10/11) and spondylolisthesis(11/13) (p<0.001). CONCLUSION: In patients with spondylolysis, signal intensity was frequently higher at the pars interarticularis and adjacent structures, and is thought to have a close relationship with degenerative endplate change and spondylolisthesis. Increases in signal intensity at the pars interarticularis and adjacent structures can help diagnose spondylolysis in patients without spondylolisthesis.
