Seven patients having midline granuloma received local irradiation from March 1983 to June 1986. Clinically, all of the 7 patients had pansinusitis with necrotic destruction of the involved sites and one case revealed colonic lesion. Each of the patients received a tumor dose of 4,000 ~ 5,000 cGy/5~6wks to the upper aerodingestive tract using a 6-MV linear accelerator. Complete and partial remission occurred in 3 patients each, and in one case, the disease progressed despite of the irradiation.

Since the entity of postmastectomy lymphangiosarcoma was first reported by Stewart and Traves in 1948, postmastectomy lymphangiosarcoma has become a well recognized, uncommon malignant tumor which occurs in the upper extremity following mastectomy for mammary carcinoma. The postmastectomy lymphangiosarcoma occurred at an average age of 63.9 years and at an average of 10 years and 3 months following mastectomy. The lymphangiosarcoma raised from blood and lymphatic vessel. The histologic appearance has been observed edematous dermis and dilated lymphatics lining with malignant cells. Most authors recommend radical amputation for treatment, either shoulder disarticulation or forequarter amputation. Other modalities of treatment including radiotherapy were considered as ineffective. The present report provides a case of the regression of postmastectomy lymphangiosarcoma with chronic lymphedima by external irradiation. Radiation therapy was used as primary therapy. Total tumor dose of 6500 cgy in 9 weeks was delivered using 6 MV x-ray and 8 MeV electron.

Angiofollicular lymph node hyperplasia (AFLNH) with well marginated lymphoid masses, is a rare benign disease of unknown etiology. The majority of the disease develop intrathoracically. Histologically this disease can be divided into the hyaline-vascular and the plasma cell types with the hyaline-vascular type prevailing. The plasma cell variant has been associated with nephritic syndrome, anemia, growth failure, fever, hyperglobulinemia, peripheral neuropathy, and hypoalbuminemia. Surgical resection is known to be treatment of choice in most cases, and radiotherapy is reserved for advanced, unresectable lesions. We report a complete remission of AFLNH in a case treated by surgical excision followed by irradiation.

Radiobiological and clinical evidences indicate that hyperthermia combined with ionizing radiation produces a significant improvement in therapeutic effect of cancer. In general, malignant cells are more sensitive to heat than normal cells in the heat range of 41~45degree C. We report the experiences obtained from 42 patients with advanced malignant neoplasms managed with 2,450 MHz microwave-induced local hyperthermia and ionizing radiation at the Department of Radiology, Kangnam St. Mary's Hospital, Catholic University Medical College. A clinical analysis of 42 thermoirradiated patients showed result of 11(26%), 15(36%), 11(26%) and 5(12%) patients with complete response (CR), partial response (PR), minor response (MR) and no response (NR), respectively. Histologically, there were 17 (40.2%) squamous cell carcinomas, 12(28.6%) adenocarcinomas and 6 (14.3%) miscellaneous cancers. Eleven patients with CR consisted of five squamous cell carcinomas, five adenocarcinomas, and one chloroma. Among 15 patients with PR were five squamous cell carcinomas, five adenocarcinomas, three unknown primary tumors, and one poorly differentiated, and miscellaneous tumor each.

OBJECTIVES: Allergen is closely related with local features and cultural environment and a new approach method regarding causes triggering aggravation is especially required due to complex and variety of ordinary residence and pollution of living environment recently. We, therefore, performed this study to inspire the necessity of identification of causative afeuts in aothmatic patients in pusan area. METHODS: We measured serum specific IgE antibody by means of chemiluminescent analyzer employing MAST, classified the level from class 0 to 4 and interpreted the result in order to identify allergen on total 262 patients consisted of inpatients and outpatients who had been presumed as extrinisic asthma and treated in this hospital during 2 and a half years from June of 1994 to December of 1996. RESULTS: 1. With regard to sex and age distribution, the rate of men versus women was 1 : 1.3, while in the distribution by age, the twenties and the thirties were the most as 29% and 26% respectively. 2. The result of interpretation of the test showed positive in 75%, 78% of which showed positive reaction compounded of 2 kinds or more. 3. If we take a look at the distribution of total IgE class in the positive area, we can find that ; Class III and class II showed the highest frequency as 47% and 37% respectively. 4. If we take a look at the distribution by age and allergen, the twenties(32%) and the thirties(30%) showed the highest frequency, the fifties, the forties and the teens showed middle frequency as 10~13% and the sixties and the seventies showed the lowest frequency as about 1%. The causative allergen appeared in the order of pollen(40%), dust(20%), food(18%), fungus(13%) and epidermis(8%). 5. The distribution of allergen by season generally showed high rate of positive appearance in spring and fall as pollen appeared in spring(44%) and fall(27%), dust appeared in fall(32%) and summer(23%), food appeared in spring(34%) and fall(29%), fungus appeared in fall(30%) and spring(28%) and epidermis appeared in spring(30%) and fall(28%). 6. With regard to the allergen: (1) In pollen allergens, trees showed higher positive frequency than weeds and trees were in the order of birch(14%), alder(13%) and hazelnut mix(12%) and weeds showed similar positive values. (2) In dust allergens, mite(D. pteronyssinus and D. farinae) showed high positive rate as 39% each. (3) In epidermal allergens, it also showed relatively even positive value among which cat's halr-dandruff was the highest as 40%. (4) In food allergens, shrimp showed the highest as 22% and others were similar as evenly positive values. (5) In fungus allergens, Candida and Stemphylium showed the highest value as 19% each. CONCLUSION: The analysis of allergen by means of MAST could be used as a valuable guide post for identifing cousative antigens for active treatment of extrinsic asthma.

To conduct a kinetic study of paraquat (PQ), we investigated 9 patients with acute PQ intoxication. All of them ingested more than 20 ml of undiluted PQ herbicide to commit suicide and arrived at our hospital early, not later than 7 h after PQ ingestion. The urine dithionite test for PQ in all of the nine patients was strongly positive at emergency room. Blood samples were obtained every 30 min for the first 2~3 h and then every 1 or 2 h, as long as the clinical progression was stable among the patients for 30 h after PQ ingestion. The area under the plasma concentration-time curve (AUCinf), which was extrapolated to infinity, was calculated using the trapezoidal rule. Toxicokinetic parameters, such as the terminal elimination half-life, apparent oral clearance, and apparent volume of distribution (Vd/F) were calculated. The maximum PQ concentration (Cmax) and the time to reach maximum PQ concentration (Tmax) were also obtained. Plasma PQ concentrations in nine patients were well described by a bi-exponential curve with a mean terminal elimination half-life of 13.1+/-6.8 h. Cmax and AUCinf were 20.8+/-25.7 mg/l and 172.5+/-160.3 h.mg/l, respectively. Apparent volume of distribution and apparent oral clearance were 50.9+/-61.3 l/kg and 173.4+/-111.2 l/h, respectively. There were a significant correlation (r =0.84; p<0.05) between the PQ amount ingested and Cmax. AUCinf also showed a significant correlation (r =0.83; p<0.05) with the PQ amount ingested. These correlations provide evidence that PQ has dose-linear toxicokinetic characteristics.

From April, 1983 through April, 1989, we have treated histologically proven 21 patients with oligodendroglima using 6 MV linear accelerator at the Division of Radiation Therapy, Kangnam St. Mary's Hospital Catholic University Medical College. These are 8% of the irradiated 246 primary brain tumors during the same period. To investigate influencing factors on the survival of irradiated 21 patients with oligodendroglioma, we analyzed the cerebral location of the nvolvements, initial symptoms, CT findings and survival rates, retrospectively. One case was lost to flow up and excluded from survival data. Of the 21 patients, thirteen were male and 8 female. Ages ranged from 5 to 68 years with a median age of 38 years. Radiation doses varied from 3960 cGy to 6480 cGy and were given for 5 to 8 weeks. All but one were supratentorial. The involvement of the frontal and parietal lobes were 10 (48%) patients in each and temporal lobe in 8 (38.1%). Histological diagnosis was made by stereotactic biopsy in 3 and postoperatively in 18. The type of surgery was divided into partial, subtotal and total resection in 7,9 and 2 cases respectively. In 6 cases, chemotherapy was also tried during or after radiation therapy. Major presenting respectively in decreasing order. In CT analysis, low density (62%), cystic mass (33%), calcification (66%) and positive contrast enhancement (42.8%) were observed as the highest frequency. Mean survival duration after radiation therapy was 38 months (K-M methods). We could not achieve statistically significant factors influencing on the survival rate after radiation therapy for oligodendrogliomas by one or two tail test.

PURPOSE: We investigate the outcomes of treatment of patients with severe comminuted distal radius fractures with volar plate fixation using a pronator-preserving approach. MATERIALS AND METHODS: Fourteen patients with severe comminution of the distal radius fractures for whom anatomical reduction of the fractures was deemed difficult to achieve with traditional approaches were enrolled. The gender ratio was 8 males to 6 females, and the average age of the patients was 64.9 years. According to the AO/OTA classification of fractures, 2 patients had 23-A3 fractures, 7 patients had 23-C2, and 5 patients had 23-C3. Radial length, radial inclination, and volar tilt were measured for radiologic evaluation. Modified Mayo wrist score (MMWS) was used for clinical outcome. RESULTS: Bony union was achieved in all 14 patients without signs of complications. The average time-to-union was 4.3 months (3-6 months). The radiological findings at the final follow-up were as follows: the average radial inclination was 20.5degrees; the average volar tilt, 7.57degrees; and the average radial length, 11.8 mm. At the final follow-up, the results of the MMWS were 'Fair' in 1 patient, 'Good' in 4, and 'Excellent' in 9. CONCLUSION: We propose that a pronator-preserving approach is an effective treatment for severe comminuted distal radius fracture.

From March, 1983 to March, 1987, 16 patients with esophageal steno-obstruction due to nonesophageal tumors were treated in the Division of Therapeutic Radiology, Kangnam St. Mary's Hospital, Catholic University Medical College. The patient characteristics, effect of radiotherapy (XRT) on esophageal steno-obstruction and survival were evaluated. The most common primary tumor was lung cancer (14/16) and the middle third of the esophagus was most frequently involved (14/16). Improved clinical response was observed in 80% of the patients who finished the planned courses of XRT. The mean radiation dose evoking the improvement of dysphagia was 2,993 cGy given over a period of 3 to 4 weeks. The Kaplan-Meier estimates of survival at 15 and 30 weeks of follow-up were 60% and 46%, respectively. In the completed group who finished the whole planned courses of XRT, survival rates were 77% and 51%, respectively. Four patients were alive over 90 weeks with normal passage of food.
