BACKGROUND: Cell-cell adhesion in tissue is mainly regulated by hornotypic interaction of cadherin molecules, which are anchored to the cytoskeleton via cytoplasmic proteins, including a-and / 3-catenin. Loss of E-cadherin and catenin have been attributed a pathogenetic role in tumor invasion. METHODS: We examined the expression of E-cadherin and a-catenin in human thyroid carcinoma by immunohistochemistry. RESULTS: Normal tissue strongly expressed E-cadherin and a-catenin. However, E-cadherin and a-catenin expression were frequently reduced in thyroid carcinoma (E-cadherin: 62.5%, a-catenin: 81.3%). But the expression of E-cadherin and a-catenin in tumors with metastatic spreading were not different with tumors without metastasis. CONCLUSION: These results suggest that reduced E-eadherin and a-catenin expression may be a sensitive marker for disturbance in the adhesive function of the junctional complex, but further evaluation with more cases is needed for confirmation of the result of the same degree of expression in tumors with metastasis.

The concept of surface replacement arthroplasty of the hip is to replace the diseased joint surface with artificial plastic and metal cup in the acetabular and femoral head respectively, and to restore the normal anatomy and gain biomechanical function. Ten cases of Wagner type's surface replacement arthroplasty performed in Department of Orthopedic Surgery, Seoul National University Hospital since July 1979 are reviewed, and their minimum follow up is two months. In terms of the Pain control and improvement of range of motion in the hip, surface replacement arthroplasty showed about the same result compared with conventional total hip. In our cases there was no one complicatian, even though it is too short to evaluate the result of this operation. Wagner recommends surface replacement arthroplasty to perform through anterior approach, but 2 cases of our ten patients that have relatively good range of motion of the hip could be operated on this surgery by anterolateral approach (oblique skin incision) without trochanteric osteotomy, because of high incedence of myositis ossification with anterior approach. It is our conclusion that surface replacement arthroplasty of the hip may be used as an interim procedure to gain time in young patient who needs conventional total hip replacement which reveals increasing complication with the lapse of time.

Twelve neglected congenital dislocations of the hip in ten patients over the age of eight years were treated by open reduction and chiari osteotomy. Reduction was aided by preoperative traction only in two hips, by femoral shortening with preoperative traction in three and by femoral shortening only in seven. The average follow up period in our series is 3 years, ranging from 1 year and 2 moths to 4 years and 5 months. The overall results were good but one case of avascular necrcsis and one case of redislocation were seen. By our experience it is thought that all old and congenitally dislocated hip in the growing age can be reduced by femoral shortening with soft tissue release, and preoperative traction for its reduction is not undispensable. The most problem in the treatment of the old congenital dislocation of the hip is the postoperative partial ankylosis in the affected hip and this problem would be overcome by delicate operative technique and meticulous hemostasis.

The dynamic blood flow is regulated by the numerous complex mechanisms. Since blood flow varies directly with the radius of the vessel, blood flow is markedly affected by small changes in the caliber of the vessels. Using the hotoplethysmography, we assessed the relative changes of blood flow after topical application of the vasoactive drugs to the femoral arteries of the rabbits. It is the purpose of this study to evaluate the immediate and delayed effects of the vasoactive drugs such as epinephrine, methylergonovine, chymopapain, and lidocaine in course of time when the drugs applied topically to the vessel. 60 rabbits were divided into 6 experimental groups. In group I, the femoral artery was surgically exposed only. In Group g-A, epinephrine was applied to the femoral artery after surgical exposure. In Group Il-B, after spplication of epinephrine, the effect of epiniphrine was reversed with lidocaine. Another drugs were applied as follows methylergonovine in Group Hl-A, methylergonovine and lidocaine in Group Ill-B as in group Il-B, Chymopapain in Group lV. The relstive changes of blood flow were measured by the photoplethymograph for 3 weeks. The results are as follows ; 1. The amplitude of the photoplethysmographic wave decreased immediately after the topical application of epinephrine, methylergonovine and chymopapain. Such an effect could be observed until the 3rd week after the topical application of the drugs, 2. The delayed dffect of reducing the amplitude could be seen during the 1st week in the epinephrine and methylergonovine treated groups. However, it was seen after 1st week in the chymopapain treated group. 3. The delayed effect of epinephrine and methylergonovine could be reversed with lidocaine. 4. It seems that lidocaine can be used clinically to preyent the delayed effect of epinephrine and methylergonovine.

Diffuse alveolar hemorrhage (DAH) is associated with severe outcomes. We report a case of acute respiratory failure that required mechanical ventilation and was clinically and pathologically diagnosed as DAH related to exposure to organic dust. A 39-year-old man, who had visited a warehouse to grade beans for purchase, was referred to our hospital for impending respiratory failure. His initial radiographic examinations revealed diffuse bilateral ground-glass opacities in his lungs and bronchoalveolar lavage resulted in progressively bloodier returns, which is characteristic of DAH. He underwent bedside open lung biopsy of his right lower lobe in the intensive care unit. Biopsy results revealed DAH and organization with accumulation of hemosiderin-laden macrophages and a few fibroblastic foci. The patient was treated with empirical antibiotics and high-dose corticosteroids and successfully weaned from mechanical ventilation. DAH might be considered in the differential diagnosis of patients with acute respiratory failure after exposure to organic particles.

PURPOSE: The aim of this study was to develop a baptist electronic Nutritional Screening Program (B-eNSP) that could be easily used to identify patients with nutrition at risk or malnutrition on their admission to hospital using an integrated medical information system and to evaluate validity, reliability and efficiency of B-eNSP. METHODS: From June 1 2009 to June 21 2009, we enrolled 496 patients for prospective research. We analyzed age, sex, weight, height, weight loss in the last 3 months, serum albumin, alteration of dietary intake, gastrointestinal symptom, functional capacity, diagnosis and its relationship to nutritional requirements, physical examination and Subjective Global Assessment (SGA). B-eNSP included body mass index (BMI), weight loss in the last 3 months, serum albumin. Each component was scored. Sensitivity and specificity were calculated to evaluate the validity of the B-eNSP. The receiver operating characteristic (ROC) curve was drawn by using B-eNSP to choose a cut-off value that maximizes sensitivity and specificity and Yoden Index. Comparison with SGA and the reliability of the B-eNSP was done using kappa statistics. RESULTS: The maximum Yoden Index was 0.866 and the cut-off value of the ROC curve was 2. A B-eNSP score higher than 2 was defined as nutrition at risk or malnutrition. Reliability of the B-eNSP was in accordance with SGA by kappa 0.845. CONCLUSION: The B-eNSP can be used efficiently to identify patients with nutrition at risk or malnutrition by simply using an integrated medical information system.
