Gastric lesion in familial polyposis coli is commonly presented with fundic gland hyperplastic polyps, but duodenal and gastric adenomas together with their carcinomatous transformation have been rarely described in familial polyposis coli mostly by case reports. We present three cases of gastric adenomas in familial polyposis coli with one in synchronous development of gastric adenocarcinoma in Korea. All three cases had the family history related to familial polyosis coli and received proctocolectomy because of synchronous development of colonic adenocarcinoma. One patient developed gastric polyposis and adenocarcinoma 8 years after colectomy, and the remaining two presented with multiple polyps either in the stomach or duodenum synchronously at the time of the diagnosis of familial polyposis coli with colonic adenocarcinoma. None disclosed any evidence of Gardner's syndrome. We conclude that association of gastric adenomas in familial oplyposis coli is not uncommon and gastric adenoma-carcinoma sequence is an another important participating mechanism to understand the histogenesis of gastric carcinoma in Korea.

BACKGROUND: Vascular dementia is common cause of dementia, second to the dementia of Alzheimer desease. However in Asia and many developing countries, the incidence of vascular dementia exceeds that of Alzheimer's disease. Though many stroke-related factors related the nature of vascular injury, e.g. infarction and hemorrhage, have not assessed yet. Clarifying the difference of electroencephalograpy and clinical prognosis between infarction and hemorrhage, the aim of this study was to elucidate the role of nature of vascular injury. METHODS: to reduce confounding factors, the study population was restricted to the patients of single hemispheric striatocapsular infarction and hemorrhage saving cortex. On admission, we checked the KMMSE and FIM scores and using quantified EEG, we analyzed occipital peak frequency and the relative background alpha, theta and delta spectra power taken from 16 derivations by averaging twenty-2 -sec epoch in infarction, hemorrhage patients and elderly controls. After 6 months follow up, we compare the MMSE, FIM score between infarction and hemorrhage group. RESULTS: 1) Compared with infarction group, hemorrhage groups had a significantly bilateral lower occipital peak freqauency and background bilateral alpha spectra power. 2) In hemorrhage group, there is lower tendency in K-MMSE after 6 month follow up compared to infarction group. CONCLUSION: This study suggests that hemorrhage show more bilateral electrophysiological dysfunction than infarction group and possible grave prognosis for vascular dementia compared to infarction group.

Microvascular anastomosis has become an essential technique in reconstructive surgery. A lot of techniques have been developed to improve patency rate and reduce operation time. But interrupted suture technique is still most widely used because of limited indication and inconvenience of other methods. A comparative study was undertaken to evaluate new microvasular anastomosis technique using fibrin glue. In this report 40 femoral arteries of Sprague-Dawley rats were anastomosed by utilizing four stay sutures which were placed 90 degrees apart and the intervals covered with fibrin glue, and by conventional eight suture method served as control. The patency rate(immediate postoperative, postoperative two weeks), time needed for vascular anastomosis, and microscopic evaluation were compared to those of conventional microvascular suture technique. Postoperative patency rate was 100% and 85% by fibrin glue technique compared to 100% and 90% by conventional technique at immediate postoperative and postoperative two weeks. Less time consumed with fibrin glue technique by 16 minutes compared to conventional technique by 21 minutes. Microscopically reendothelization was complete with smooth and less injured inner lining and also less inflammatory response by fibrin glue technique compared to conventional technique.

For prevention of limitation of range of motion due to arthrofibrosis of the knee joint after anterior cruciate ligament reconstruction, it is accepted in general that the operation should be delayed for about three weeks after injury. We studied the duration form operation to time of full range of motion, and analized the results in forty-eight patients who had undergone arthroscopic anterior cruciate ligament recostruction using the autologous bone-patella tendon-bone graft and early CPM, range of motion exercise during Feb. 1991 and June 1994. The results were as follows: 1. The average interval from injury to operation were 1.3 weeks in acute injury group, 6 weeks in subacute injury group and 20.7 months in chronic group. The average interval from operation to full range of motion were 7.1 weeks in acute injury group, 5.7 weeks in subacute injury group and 3.0 weeks in chronic group. 2. In acute injury group, 14(93.3%) of 15 cases showed full extesion and only 1 case(6.7%) showed the limitation of extension less than 5 degrees. In subacute injury group, 6(85.7%) of 7 cases showed full extension but1 case(14.3%) showed the limitation of extension less than 5 degrees. On the other hand in the chronic injury group, all the 26 cases(100%) of the patients showed full extension. 3. In acute injury group, 14(93.3%) of 15 cases showed full flexion and only 1 cases(6.7%) showed the limitatin of flexion less than 5 degrees. In subacute injury group, 6(85.7%) of 7 cases showed full flexion but 1 case(14.3%) showed the limitation of flexion less than 5 degrees. On the other hand in the chronic injury group, 23(88.5%) of 26 cases could flex to full range of flexion, and 3 cases(11.5%) revealed limitation of flexion less than 5 degrees. 4. The limitation of ROM mainly due to arthrofibrosis can be prevented by early range of motion execise and active rehabilitation in the acute or chronic anterior cruciate ligament reconstruction using the autograft bone-patella-bone graft. Although in acute patients the interval from operation to full ROM can be prolonged, the full ROM can be achieved after all.

PURPOSE: The definition of locally advanced breast cancer (LABC) includes stage III breast cancer. In order to investigate the factors influencing on the final outcome we analysed the data of LABC patients that received neoadjuvant chemotherapy prior to definitive surgery. METHODS: 122 LABC patients, who underwent neoadjuvant chemotherapy between 1980 and 1997, were included for the analysis. Clinical responses to neoadjuvant chemother apy were classified as complete response (CR), partial response (PR), and no response (NR). Overall survival (OS), Loco-regional relapse free survival (LRRFS), and distant relapse free survival (DRRFS) probabilities were investigated according to initial clinical stage, clinical response to neoadjuvant chemotherapy, and pathologic stage after neo adjuvant chemotherapy. Statistical analyses were performed with chi2-test, Kaplan-Meier, and Cox-regression methods using SPSS. RESULTS: The mean age at diagnosis was 47 years old (range 31~73) and median follow-up period was 61.6 months (range 3~227 months). Among 122 LABC patients, 69 (56.6%) were included in stage IIIA, 37 (30.3%) in stage IIIB, and 16 (13.1%) in IIIC at diagnosis. 10 patients (8.2%) have shown CR, 85 (69.7%) patients PR, and the remaining 27 (22.1%) patients showed NR. The overall response rate to neoadjuvant chemotherapy was 77.5%. However, only 51 (41.8%) were demonstrated to have pathologically down-staged results. There were 32 loco-regional recurrences and 59 distant metastases. All of the initial clinical stage, clinical response to neoadjuvant chemotherapy, and pathologic stage influenced the final outcome of 10 year OS, LRRFS, DRFS. However, in multivariate analysis pathologic stage after neoadjuvant chemotherapy was the most influencing factor on the final outcome. CONCLUSION: Pathologic stage after neoadjuvant chemotherapy could be the most important prognostic factor of the LABC.

PURPOSE: A phyllodes tumor is a rare disease of the breast, which shows various clinicopathological aspects. However, there is some controversy over its clinical behavior, pathologic characteristics, and local recurrence rates. Therefore, the clinicopathological characteristics of phyllodes tumor and the risk factor that influence a local recurrence after surgery were analyzed. METHODS: The medical records of 56 patients with a phyllodes tumor who had undergone surgery at the Department of Surgery, Yonsei University, from 1986 to 1998, were analyzed retrospectively. The median follow up period was 57.2 months (12~245 months). The microscopic slides were re-examined and the pathologic criteria analyzed were cellular atypia, stromal cellularity, pleomorphism, necrosis, differentiation, tumor margin, and number of mitoses. The malignancy was reclassified using the histological criteria reported by Pietruszka et al. (benign was 0~4 mitoses/10 high- power fields, borderline 5~9 mitoses, and malignant more than 10 mitoses). The clinical features evaluated included age, preoperative diagnosis, tumor size, surgical methods, and local recurrence. RESULTS: The mean age was 41 years 14~69 years) and the mean tumor size was 4.5 cm (1~12 cm). Only 9 cases (16.1%) were preoperatively diagnosed as having a phyllodes tumor. The most commonly performed surgical procedures were local or wide excision (46 cases, 82.1%), and a mastectomy in 10 cases (17.9%). Out of 56 cases reviewed, 43 (76.8%) were confirmed as being a benign, 7 (12.5%) as being a borderline, and 5 (1.8%) as being a malignant phyllodes tumor. Cellular atypia was minimal in 40 cases (71.4%) and prominent in 14 cases (25.0%). The stromal cellularity was minimal in 32 cases (57.1%) and prominent in 23 cases (41.1%). Pleomorphism and necrosis were represented in only 1 case (1.8%). The tumor margin was infiltrating in 11 cases (19.6%) and pushing in 43 cases (76.8%). A local recurrence developed in 9 cases (16.1%). There were no dependable histopathological features to predict a local recurrence except for cellular atypia, stromal cellularity, and an infiltrating tumor margin. CONCLUSION: From the above results, the strong prognostic factors that can be used to predict a local recurrence appear to be cellular atypia, stromal cellularity, and an infiltrating tumor margin.

One hundred seven isolates of Staphylococcus aureus from bovine mastitis were investigated for colony morphology in serum-soft agar (SSA), autoagglutination in salt, and capsular serotype. Capsular polysaccharide (CP) was purified and quantified from the extracts of clinical isolates. Overall, 89 isolates (83.2%) were diffuse in the SSA, without any difference in the proportion of diffuse colony between type 5 and type 8 strains. Some strains exhibited compact colonies in the SSA and expressed CP as determined by an enzyme-linked immunosorbent assay, indicating that compact morphology does not exclude encapsulation. The majority of the strains (11/12) showed autoagglutination in the salt aggregation test. The serotype 336 accounted for 46.7% of the isolates followed by serotype 5 (12.1%) and serotype 8 (12.1%). Particularly, twenty-six (24.3%) isolates reacted with two serotypes; 7 for type 8/336 and 19 for type 5/336. Five isolates (4.7%) were nontypeable with monoclonal antibodies specific for CP serotype 5, 8, or 336. The CP concentration in culture supernatants varied with the serotypes, and the total amount of CP produced by cells grown in a liquid medium was much less than that produced by cells grown on a solid medium. The Western blotting indicated that the CP bands of S. aureus serotype 5 and 8 were ranged in the molecular mass of 58-84 kilodalton (kDa), with additional bands in the region of approximately >or= 48 or Agglutination Tests ; Animals ; Bacterial Vaccines/administration & dosage ; Cattle ; Cattle Diseases/immunology/microbiology ; Female ; Mastitis, Bovine/*microbiology ; Polysaccharides, Bacterial/*classification/isolation & purification ; Serotyping/methods/veterinary ; Staphylococcal Infections/immunology/*veterinary ; Staphylococcus aureus/*classification/*immunology/isolation & purification
