1.Radiographic Appearance of the Symphysis Pubis: Criteria of Diastasis of Symphysis Pubis after Normal Delivery.
The Journal of the Korean Orthopaedic Association 1999;34(5):969-972
PURPOSE: This study was performed to evaluate the width of symphysis pubis and its radiographic appearance in different age and sex, and it was aimed to establish a radiographic diagnosis criteria for diastasis of the joint. MATERIALS AND METHODS: The width and the appearance of symphysis pubis were observed by pelvic X-ray in 92 males and 169 females who had no history of any joint disease. The mean width of symphysis pubis was calculated and data were analyzed by age, sex and parity using student t-test. RESULTS: The mean width of symphysis pubis was 2.88+/-0.71 mm in male group and was 3.24+/-0.68 mm in female group. It was 3.34+/-0.84 mm in parturient and 2.82+/-0.55 mm in nullipara and the difference between these two groups was significant (P<0.05). Osteoarthritic changes were noted in most cases over 60 irrespective of sex. CONCLUSIONS: Based on the results from this study and reported value of physiological relaxation of symphysis pubis through pregnancy and labor, a separation over 6 mm and/or a vertical migration over 3mm can be diagnosed as diastasis of symphysis pubis. This criteria would facilitate the earlier diagnosis of relaxation and separation of this joint by labor or trauma.

The authers performed long coloaofiherscopy with barium enema study on 134 cases, of coloreatal diseasea, who had been admitted to the department of Internal Medicine, Kwangiu Christian Hospital from July 1984 to Aupist 1986, The results were following: 1) Among 134 cases of colonoacopy, abnormal findings were 70 cases (52.2%) and normal findings 64 cases (47.8%). 2) among 70 cases of colonoscopic abnormal findings, nonspecific inflammatory colitis were 27 cases, colon tuberculosis 15 cases, colon and rectal cancer 14 cases, colon polyps 8 cases, ulcerative colitis 3 cases, internal hemorrhoid 2 cases, sigmoid diverticular 1 case. 3) The cases in which the findings of barium contrast enema were compatible with those of colonoscopy were 84 cases (62.7%), not compatible 50 cases(37.3%). There were not compatible with findings in 4 cases of colon cancer (10 cases), 7 cases of colon tuberculosis (15 cases), 4 cases of colon polyps (8 cases), 1 case of ulcerative colitis (3 cases). 4) The insertion ratio to ileocecal valve was 79.1%. The rate of correct approach by a colonoscopy to the lesion site shown at barium contrast enema was 94.1%

A finite element analysis has been utilized to analyze stress and strain fields and design a new configuration in orthopedics and implant dentistry. Load transfer and stress analysis at implant bone interface are important factors from treatment planning to long term success. Bone configuration and quality are different according to anatomy of expecting implantation site. The purpose of this study was to compare the stress distribution in maxilla and mandible according to implant length and bone engagement types. A three dimensional axi-symmetric implant model(Nobel Biocare, Gothenburg, Sweden) with surrounding cortical and cancellous bone were designed to analyzed the effects of bone engagement and implant length on stress distribution ANSYS 5.5 finite element program was utilized as an interpreting tool. Three cases of unicortical anchorage model with 7, 10, 13mm length and four cases of bicortical anchorage model with 5, 7, 10 and 13mm lenght were compared both maxillary and mandibular single implant situatiion. Within the limits of study, following conclusions were drawn. 1. There is difference in stress distribution according to cortical and cancellous bone thickness and shape. 2. Maximum stress was shown at the top of cortical bone area regardless of bone engagement types. 3. Bicortical engagement showed less stress accumulation when compared to unicortical case overall. 4. Longer the implant fixture length, less the stress on cortical bone area, however there is no difference in mandibular bicortical engagement case.

Emergency endoacopy was performed in 315 patients for recent four years The source of upper GI bleeding in these 315 caaes were as follows: Esophageal varix(93), gastric ca(39), Mallory-weiss syndrome(14), gastric ca(38), Duodenal ulces(21), Erosive gastritis(14), Marginal ulcer(2), Combined case(24) Unknown cases(10), Essentiall Tx was not performed in 4 died case because of poor general conditions, After check up BP, Heart, Pluae rate, that examination was performed during drip infusion to be 'safety of cireulatary system. No compication were encountered. To confirm the source of bleeding at earlier stage, was useful to decid which way, that is conservative of surgical therapy in which better for the Management. The results are as follows: 1) The sex incidence of upper GI bleeding showed Male predominance c a ratio 4. 6: 1 and peak age groups were 4th & 5th decade. 2) Endoscopic diagnosis of npper GI bleeding in the studied case were in the order of Esophageal varix bleeding(29%), Gastric ulcer (23. 5%), Mallory weiss syndrome(12. 4%) Duodenal ulcer(6.7%) Erosive gastritis(4.4%) We could not find the bleedi site in 3.2% of the studied case. 3) The cause of emergeney endoseopy are Melena(19%), Hemstenesis(22.0%) and ccenbined (58. 4%) 4) Among the 315 cases of upper GI bleeding, 70. 1% of the cases revealed moderste degree of bleeding. 5) Among the 315 cases of apper BI bleeding, 28. 1% of the cases were confirmed of inducing factor. 6) Among the 315 cases of upper BI bleeding, 69% of the cases received an endcrscopic examination within 72 hr after initial episode of bleeding.

OBJECTIVES: Since Mountain proposed the new staging system of non-small cell lung cancer in 1986, the indications for operation of NSCLC have been extended. However, operative mortality is from 3 to 6%. Therefore it is important to reduce unnecessary operation and to evaluate unresectability of tumor correctly, preoperatively The purpose of this study is to find out the causes of unresectability in patients who were initially thought to be resectable preoperatively. METHODS: By retrospective analysis, 64 patients out of 291 NSCLC patients who were undergone operation for curative resection in Seoul National University Hospital from Jan. of 1987 to Dec. of 1991, ware found to be unresectable at operating roost were selected for this study. Out of 64 patients,42 were evaluable. The analysis was focused on the change of pre- & post-operative staging and the causes of unresectability of tumors. RESULTS: Among B2 patients with unresectable tumor who could be evaluated, preoperative CT finding showed resectable tumors in 55% (23 patients) and suspicious for unresectable tumors in 45% (19 patients). The causes of unresectability were technically unresectable T3 lesions in 7% (3 patients), T4 lesions in 62% (26 patients), N2 lesions in 17% (7 patients) and N3 lesions in 14% (6 patients). CONCLUSION: The major causes of unresectability of NSCLC were pulmonary artery invasions. It is suggested that careful evaluation of mediastinal structure, especially great vessels by additional imaging technique other than CT (like MRI) is indicated in selected NSCLC cases.
