Posterior reversible encephalopathy syndrome (PRES) is a transient condition characterized by altered mental status, seizure, headache, and visual disturbance with typical neuro-imaging findings in the bilateral parieto-occipital regions. Clinicians should be aware of this syndrome because delayed diagnosis and treatment result in irreversible neurologic deficits. We present the case of a 77-year-old male diagnosed with PRES in the setting of postoperative critical illness caused by small-bowel strangulation.

PURPOSE: To find the more effective treatment methods that improving thesurvival of patients with glioblastoma multiforme(GBM), we analyze the prognostic factors and the outcome of therapy in patients with GBM. METHODS AND MATERIALS: One hundred twenty-one patients with a diagnosis of GBM treated at Severance Hospital between 1973 and 1993 were analyzed for survival with respect to patients characteristics, that is, duration of symptom, age, and Karnofsky performance status, as well as treatment related variables such as extent of surgery and radiotherapy. RESULTS: The median survival time(MST) and 2-year overall survival rate (OSR) of the patients with GBM were 13 months and 20.8%, respectively. Duration of symptom, age, Karnofsky performance status(KPS), radiotherapy, and extent of surgical resection were associated with improved survival in a univariate analysis. Patients whose duration of symptom was longer than 3 months, had the 2-year OSR of 47.2%(p=0.0082), who were younger than age 50, 32.9%(p=0.0003). In patients with a KPS of 80 or higher, the 2 year OSR was 36.9%(p=0.0422). Patients undergoing radiotherapy had the 2-year OSR of 22.9%(p=0.030), and surgical resection of 23.3%(p<0.000). A cox regression model confirmed a significant correlation of duration of symptom, age, radiotherapy,and extent of surgical resection with survival, excluding KPS(p=0.8823). The 2-year OSR were 22.3% and 19.4%, combined with chemotherapy or without, respectively(p=0.06028). The duration of symptom of 3 months or shorter. 50 years of age or older, and undergoing stereotactic biopsy only were considered as risk factors. then patients without any risk factors had the MST of 29 months and 2-year OSR of 53.9% compared to 4 months and 0% for patients who had all 3 risk factors. Most of all treatment failure occurred in the primary tumor site(86.4%) CONCLUSION: The duration of symptom, age, radiotherapy, and extent of surgical resection were a prognostically significant independent variables. To get a better survival, it seems to be reasonable that the study design which improves the local control rates is warranted.

PURPOSE: Recurrent bile duct stones, following biliary surgery, cause many difficult problems and reoperation on the biliary tract has limitation due to high mortality and morbidity. In recent years, various non-operative modalities for the management of recurrent stone have been developed and reoperation on biliary. This study was designed to determine the factors contributing to the success rate, and to investigate the optimal treatment method, of reccurrent biliary stones. METHODS: Thirty-nine patients, treated by percutaneous transhepatic stone removal (PTBD group), and 42 treated by a common bile duct exploration (operation group), at Chung- Ang University Hospital, between January 1999 and August 2002, were retrospectively analyzed. RESULTS: Complete removal (Success) was achieved in 82.1 and 86.1% of the cases of the PTBD and operation groups, respectively. There were no significant differences observed relating to the sex, age, duration of hospital stay, cost, success rate. However, the complication rate was significantly decreased in the PTBD group (8 cases (20.5%) vs. 22 cases (51.2%) P=0.0057). CONCLUSION: Form the comparison of the operation and PTBD groups, similar success rates were observed. Percutaneous transhepatic stone removal is also an effective method for the management of recurrent bile duct stones. After studying more cases, re-evaluation must be performed concerning the potential advantages of percutaneous transhepatic stone removal.

PURPOSE: Although using the high energy photon beam with conventional parallel-opposed beams radio-therapy for nasopharyngeal carcinoma, radiation-induced xerostomia is a troublesome problem for patient. We conducted this study to explore a new parotid gland sparing technique in 3-D conformal radiotherap (3-D CRT) in an effort to prevent the radiation-induced xerostomia. MATERIALS AND METHODS: We performed three different planning for four clinically node-negative naso-phar yngeal cancer patients with different location of tumor(intracranial extension, nasal cavity extension, oropharyngeal extension, parapharyngeal extension), and intercompared the plans. Total prescription dos <. Was 70.2 Gy to the isocenter, For plan-A, 2-D parallel opposing fields, a conventional radiotherapy technique, were employed. For plan-B, 2-D parallel opposing fields were used up until 54 Gy an < 3 afterwards 3-D non-coplanar beams were used. For plan-C, the new technique, 54 Gy was delivered b r 3-D conformal 3-port beams (AP and both lateral ports with wedge compensator; shielding both superficial lobes of parotid glands at the AP beam using BEV) from the beginning of the treatment and early spinal cord block (at 36 Gy) was performed. And bilateral posterio r necks were treated with electron after 36 Gy. After 54 Gy, non-coplanar beams were used for cone-down plan. We intercompared dose statistic; Dmax, Dmin, Dmean, D95, D05, V95, V05, Volume receiving 46 Gy) and dose volume histograms (DVH) of tumor and normal tissues and NTCP values of parotid glands for the above three plans. RESULTS: For all patients, the new technique (plan-C) was comparable or superior to the other plans in target volume isodose distribution and dose statistics and it has more homogenous target volume, coverage. The new technique was most superior to the other plans in parotid glands sparing (volume receiving 46 Gy: 100, 9 B, 69% for each plan-A, B and C). And it showed the lowest NTCP value of parotid glands in all patients (range of NTCP; 96-100%, 79-99%, 51-72% for each plan-A, B and C). CONCLUSION: We conclude that the new technique employing 3-D conformal radiotherapy at the beginning of radiotherapy and cone down using non-coplanar beams with early spinal cord block is highly recommended to spare parotid glands for node-negative nasopharygeal cancer patients.

Malignant lymphoma of uterus and ovary is a very rare disease. Under the impression of ovarian malignancy, subtotal abdominal hysterectomy with bilateral salpingo-ophorectomy was done due to severe pelvic adhesion. Histopathologic and immunohistochemical study demonstrated the tumor to be diffuse large B-cell lymphoma of the ovary with involvement of the uterus. So, we have experienced a case of malignant lymphoma of the uterus and ovary in Department of Obstetrics and Gynecology and Pathology, College of Medicine Korea University and discribed our case with a brief review of literature.

A 44 years old woman was admitted to Inha University hospital in semicomatose state. An electrocardiogram (ECG), taken in the emergency room, showed ST segment elevation in the precordial leads. She underwent a urgent echocardiography. It showed that there was akinesia of anteroseptal segment from the mid left ventricle to the apex and inferior segment from the mid left ventrile to the lower mid left ventricle. With the impression of acute myocardial infarction (AMI), she underwent a urgent coronary angiography. There was no significant luminal narrowing of the right or the left coronary arteries but the left ventriculography revealed akinesia of anterolateral and diaphragmatic segments of the left ventricle. Computerized tomography (CT) of the brain, taken shortly after coronary angiography, showed subarachnoid hemorrhage. The abnormal ECG and echocardiography findings, simulating acute myocardial infarction, were assumed to be caused by coronary vasospasm derived from subarachnoid hemorrhage accompanied by massive adrenergic discharge.

PURPOSE: The goal of this study was to improve the accuracy of three-dimensional conformal radio therapy (3-D CRT) by measuring the treatment setup error and physiological movement of liver based on the analysis of images which were obtained by electronic portal imaging device (EPID). MATERIALS AND METHODS: For 10 patients with hepatocellular carcinoma, 4-7 portal images were obtained by using EPID during the radiotherapy from each patient daily. We analyzed the setup error and physiological movement of liver based on the verification data. We also determined the safety margin of the tumor in 3-D CRT through the analysis of physiological movement. RESULTS: The setup errors were measured as 3 mm with standard deviation 1.70 mm in x direction and 3.7 mm with standard deviation 1.88 mm in y direction respectively. Hence, deviation were smaller than 5 mm from the center of each axis. The measured range of liver movement due to the physiological motion was 8.63 mm on the average. Considering the motion of liver and setup error, the safety margin of tumor was at least 15 mm. CONCLUSION: EPID is a very useful device for the determination of the optimal margin of the tumor, and thus enhance the accuracy and stability of the 3-D CRT in patients with hepatocellular carcinoma.

PURPOSE: To obtain the optical treatment method in patients with endometrial carcinoma(clinical stage FIGO I, II) by comparative analysis between preoperative radiotherapy(pre-op R) and postoperative radiotherapy(post-op RT). MATERIALS AND METHODS: A retrospctive review of 62 endometrial carcinoma patients referred to the Yonsei Cancer Center for radiotherapy between 1985 and 1991 was undertaken. Of 62 patients, 19 patients(Stage I; 12 patients, Stage II; 7 patients) received pre-op RT before TAH(Total Abdominal Hysterectomy) and BSO(Bilateral Salphingoophorectomy) (Group 1) and 43 patients( Stage 1; 32 patients, Stage 2; 11 patients) received post-op RT after TAH and BSO (Group 2). Pre-op irradiation was given 4-6 weeks prior to surgery and post-op RT was administered on 4-5 weeks following surgery. All patients exept 1 patient(Group2; ICR alone) received external irradiation. Seventy percent(13/19) of pre-op RT group and 54 percent(23/42) of post-op RT group received external pelvic irradiation and intracavitary radiation therapy(ICR). External radiation dose was 39.6-55Gy(median 45Gy) in 5-6week through opposed AP/PA fields or 4-field box technique treating daily, five days per week, 180cGy per fraction. ICR doses were prescreibed to point A(20-39.6 Gy, median 39Gy) in Group 1 and 0.5cm depth from vaginal surface (18-30 Gy, median 21Gy) in Group2. RESULTS: The overall 5year survival rate was 95%. No survival difference between pre-op and post-op RT group.(89.3% vs 97.7%, p>0.1) There was no survival difference by stage, grade and histology between two groups. The survival rate was not affected by presence of residual tumor of surgical specimen after pre-op RT in Group 1(p>0.1), but affected by presence of lymph node metastasis in post-op RT group(p<0.5). The complication rate of pre-op RT group was higher than post-op RT.(16% vs 5%) CONCLUSION: Post-op radiotherapy offers the advantages of accurate surgical-pathological staging and low complication rate.
