The clinicopathologic characteristics, treatments and prognosis of retinoblastoma, the most common intraocular tumor in children, were studied retrospectively in 101 cases(128eyes) who visited our clinic from 1987 to 1996. All patients were followed for 2 years or longer. Twenty seven cases were bilateral and seventy four cases were unilateral,. Eihgty four eyes were enucleated. Twenty one eyes were successfully treated by conservative modality. The rest refused any type of treatment. Orbital recurrence or distant metastasis were observed in 5 cases after enucleation without systemic treatment, and one died in spite of irradiation and aggressive chemotherapy. It is widely recognized that the prognosis for survival of retinoblastoma patients, especially unilateral, is excellent, however the authors emphasize the importance of careful postoperative histopathologic review and long term periodic follow-up to improve long-term prognosis.

Thymic cyst is relatively rare tumor which usually occurs in the neck or mediastinum. Cervical thymic cyst is usually situated laterally and deep to the anterior border of the sternocleidomastoid muscle, simulating a branchial cyst. Thymic cyst of the mediastinum is usually detected incidentally and differential diagnoses include cystic degeneration of thymoma, and cystic teratoma. Two case of a cervical and a mediastinal thymic cysts were reported. The one was a cervical thymic cyst developed slowly growing mass in a 53-year-old male a for 10 years. The cyst was unilocular and measures 5.4x2.9x2.8 cm with columnar or squamous cell linings. The other is a mediastinal thymic cyst developed in a 37-year-old female with chest discomfort for 7 months. The cyst was uniocular and measures 2.8x2.2x2.0 cm. The epithelial lining of the cyst was largely desquamated and covered by macrophages with cholesterol granuloma. Involutional thymic stissue in their walls were noted in both cysts. In both cases presence of thymic tissue in the wall of the cyst thought to be the most important diagnostic feature.

Endoscopic retrograde cholangiopancreatography (ERCP) is one of the most useful diagnostic tool in biliary and pancreatic disease. However, ERCP cannot be performed successfully in all patients. Cannulation failure is the most common cause of failure of ERCP. Mechanical pathologies, such as peri-Vater diverticulum, cancer of the papilla of Vater, and impacted stone were the common causes of cannulation failure. We experienced two cases of carcinoma of the papilla of Vater in whom cholangiography and insertion of the nasobiliary tube were performed througth an artificial choledoehoduodenal fistula made by a needle type diathermy knife, beacuse cannulation to the duct was failed due to the tumor.

We present an ultrastructure of an incidentally found renomedullary interstitial tumor also called as medullary fibroma in a 77 year-old female who had a metastatic adenocarcinoma of colon to the ureter. This tumor was a small and grayish white nodule in renal medulla, measuring 0.4 x 0.4 cm. Microscopically the tumor composed of spindle cells, with some vacuolation and intercellular collagen fibers. The electron microscopic observation of the spindle cells reveal that nuclei are spindle to oval shape and cytoplasm contain abundant rough endoplasmic reticulum, polyribosome without microfilaments and cisterna like structures supporting that the renomedullary interstitial cell tumor is renal interstitial cell origin than fibroblasts.

BACKGROUND: The propose of this study was to identify the level of medical technologists' perception of and compliance with hospital infection control guidelines. METHODS: A questionnaire survey was conducted for 65 medical technologists working at three university hospitals in Seoul and Kyunggi areas. The questionnaire was composed of 34 questions on the general characteristics (14 items) of individual responders and about infection control guidelines (20 items). Their response was marked on the basis of 5 points for each question. RESULTS: The mean scores of the perception of and compliance with the infection control guidelines were 4.62+/-0.34 and 3.85+/-0.42, respectively. The female technologists scored significantly higher than did the male counterparts in the participation level of the infection control guidelines (P<0.05). The medical technologists who had participated in an infection control educational program were more likely than those who had not to show a higher compliance level on the infection control guidelines (P<0.05). CONCLUSION: The study demonstrated that the development of infection control educational programs for medical technologists and a supportive policy of the hospital administration should contribute to the prevention of nosocomial infections.

PURPOSE: The purpose of this study was to evaluate the spectrum of MR characteristics of cystic acoustic neurinomas and to correlate with pathologic findings. MATERIALS AND METHODS: We retrospectively reviewed the MR findings of 12 patients with cystic acoustic neurinomas. The signal intensity and enhancement pattern of the cystic components as well as the location relative to the tumors were analyzed. RESULTS: A total of 30 cysts were found in 15 acoustic neurinomas;28 were intratumoral cysts and the remaining two were extratumoral cysts. The signal intensity of all 28 intratumoral cysts was higher than that of CSF on Tl-weighted images, and isointense to CSF on T2-weighted images, while the signal intensity of the two extratumoral cysts was same as CSF on both Tl-weighted and T2-weighted images. Rim enhancement was seen in 27 of 28 intratumoral cysts but in none of the two extratumoral cysts. CONCLUSION: We concluded that intratumoral cyst was due to tumoral necrosis, hemorrhage or degenerative change and extratumoral cyst due to secondary arachnoid cyst formation.

Leiomyoblastoma is uncommon and has been known as a neoplasm of smooth muscle origin. However, with recent pragress in immunohistochemical staining techniques, many clinicopathological discrepancies have been pointed out about the origin of leiomyoblastoma. We present here a case of gastric leiomyoblastoma did not expressed desmin and neuron specific enolase, and was thought to be of unknown derivation.
