We studied prospectively on the grade of severity of reflux gastritis after Billroth- I (15 patients and B-II (66 patients) using gastrofiberscopy mostly 3~4 montsh after operations from December 1988 to February.The grade of severity af gastritis was arbitarily defined as follows; Grade 0-almost no reflux of bile and no redness on gastric mucosa. Grade 1-mild redness of the mucosa limited within an inch from anastomotic line. Giade 2-Edema and mucosal redness involves almost one half of remaining gastric mucosa. Grade 3-the above cbanges involves most of remnant gastric mucosa. Gtade 4-in addition to grade 3, friability of mucosa and/or, erosions is noted. Grade 5- ulceraitions of mucosa in addition to the above changes. Using the above defined criteria, we obtained the following results; 1) there was no rieflux gastritis in one patient in B- I group and remainders have varing grades of reflux gastritis, ie; 93% (14/15) (see Table 2). 2) In B- II reconstructed patients, grade 0 was 2 patients and remainder had reflux gastrits, ie; 96% (64/66) (see table 4). 3) Grade 5 patients have ulcerations in the esophagus and grade 2 changes in the stomach.

PURPOSE: The purpose of this study was to examine the significance of increased bone density according to whether bone grafts were applied using demographic data with Cone Beam Computed Tomography (CBCT) and to compare the bone densities between before and after implant prosthesis using the Hounsfield index. MATERIALS AND METHODS: Thirty-six randomly selected computed tomography (CT) scans were used for the analysis. The same sites were evaluated digitally using the Hounsfield scale with V-Implant 2.0(TM), and the results were compared with maxillary posterior bone graft. Statistical data analysis was carried out to determine the correlation between the recorded Hounsfield unit (HU) of the bone graft and implant prosthesis using a Mann-Whitney U test and Wilcoxon Matched-pairs test. RESULTS: The bone grafted maxillary posterior teeth showed an increase in the mean values from-157 HU to 387 HU, whereas non-grafted maxillary posterior teeth showed an increase from 62 HU to 342 HU. After implantation, the grafted and non-grafted groups showed significantly higher bone density than before implantation. However, the grafted group showed significantly more changes than the non-grafted group. CONCLUSION: Bone density measurements using CBCT might provide an objective assessment of the bone quality as well as the correlation between bone density (Hounsfield scale) and bone grafts in the maxillary molar area.

We tried to correlate brain CT findings with clinical state at admission and outcome at discharge in 42 selected cases from 94 adult patients under the diagnosis of tuberculous meningitis at Seoul National University Hospital during last four years from 1981. Their clinical state at admission and outcome at discharge were classified into three groups by severity of symptoms, respectively. The final outcome of them were well correlated with their clinical states at admission. Observed abnormal brain CT findings in this series were hydrocephalus (74%), dirthy cisternal enhancement (52%), infraction (38%), periventricular low density (36%), and tuberculoma (19%). The poorer the clinical state at admission and outcome at discharge, the more frequent the abnormal brain CT findings, especially of periventricular low density and infraction. But periventricular low density without infarction seemed to affect more deleterious effect on clinical state at admission than on final outcome.

BACKGROUND/AIMS: The endoscopic mucosal resection has now been adopted for a useful modality in both curative therapy and accurate diagnosis of early gastric cancer. A retrospective study was done to evaluate the indication and the limitation of endoscopic mucosal resection of early gastric cancer. METHODS: We studied 20 cases of early gastric cancer treated by endoscopic mucosal resection in Chungnam National University Hospital from November, 1995 to July, 1997. RESULTS: 1) The size affected the curability: 83. 3% of lesions less than 2 cm and 50. 0% of those larger than 2 cm were resected completely. 2) The depth of cancer invasion affected the curability: 87. 5% of lesion confined to mucosa were resected completely, while all of submucosal cancers were resected incompletely. 3) Among fourteen cases resected completely, three cases of lesions larger than 2 cm were residual cancer and two of those less than 2 cm were recurred locally. CONCLUSIONS: To be a curative therapy by endoscopic mucosal resection of early gastric cancer, we think that careful selection of the lesion, that is lesion less than 2cm and confined to mucosa, is necessary

PURPOSE: In this retrospective study, we attempted to evaluate the treatment outcome and the prognostic factors of thymoma treated with surgery, radiotherapy and chemotherapy. METHODS AND MATERIALS: Between 1979 and 1998, 55 patients with thymoma were treated at the Seoul National University Hospital. Of these, 11 patients underwent surgery only, 33 patients received postoperative radiotherapy and 11 patients received radiotherapy only. Twenty-three patients had gross total resection and 21 patients subtotal resection. For postoperative radiotherapy, the radiation dose consisted of 41.4-55.8 Gy. The average follow-up was 64 months, and ranged from 2 to 160 months. The sex ratio was 1:1 and the median age was 48 years (15-74 years). Overall survival and disease-free survival were determined via the Kaplan-Meier method, and the log-rank was employed to evaluate for differences in prognostic factor. RESULTS: The five- and 10-year survival rates were 87% and 65% respectively, and the median survival was 103 months. By univariate analysis, only stage ( p=0.0017) turned out to be significant prognostic factors of overall survival. Also, stage ( p=0.0007) was significantly predictive for overall survival in mutivariated analysis. CONCLUSION: This study showed the stage was found to be important prognostic factors, which influenced survival. Especially, as incomplete resection is related with poor results, complete resection is important to cure the invasive thymoma.

We report three cases of rat mite dermatitis caused by Ornithonysus bacoti(Hirst, 1913), commonly referred to it as the tropicalrat mite. The first case, a 26-year old female had multiple pinhead sized vesicles with peripheral erythematous macule on the upper arms. The second case, a 34-year-old femal had multiple variable sized vesicles with erythematous base on the extremeties. The third case, a 43-year old male had multiple erythematous macules and papules with central punctum on the trunl: and extremities. Histopathologic sections from lesions of the first and second patient showed moderate perivascular lymphahistiocytic infiltration intermingled with some eosinophils. Causative mites, Ornithonyssus bacoti, female were collected around the skin lesion in rase 1, from the house dust in case 2 and furniture in case 3.

Juxtaductal coarctation is usually distal to the origin of the left subclavian artery, occasionally the orifice of the subclavian artery is involved in the coarctation and partially obstructed. An anomalous origin of the right subclavian artery from the descending aorta below the coarcted segment is also occasionally encountered. Reversed vertebral artery flow to a subclavian artery arising at or below a coarctation may produce the subclavian steal syndrome. Rarely both subclavian arteries arise beyond the coarctation. These abnormal subclavian arteries are important in clinical diagnosis and treatment. We report a case of Turner syndrome with coarctation, which present as juxtaductal type and the left subclavian artery from the descending aorta below the coarcted segment with reversed vertebral artery flow to a subclavian artery producing the subclavian steal syndrome. Resecton of coarctation segment and end-to-end anastomosis was successfully performed after transfer of left subclavian artery to distal segment of descending aorta.
