  • Purpose: In this report we are going to discuss about the functional evaluation and the outcome of treatment of metastatic tumor in the lower extremities treated with tumor prosthetic arthroplasty. Materials and Methods: This report is based on nine patients diagnosed as a metastatic tumor and treated by tumor prosthetic arthroplasty, from June 1998 to December 2001. Age of the patients ranged from 49 to 63 with the average of 56.3. The average follow up period was 23.4 months. Two patients had lung cancer, three had breast cancer, two had renal cancer, one colon cancer, and one had multiple myeloma. All these were primary cancers. The site of metastasis were six in proximal femur, two in distal femur, and one in proximal tibia. Tumor excision was performed after biopsy in following the principle of primary tumor management. Excision with wide surgical margin was tried as possible could. Six cases were treated with tumor prosthesis, and the other three cases were reconstructed with bone cement and arthroplasty. Results: The functional evaluation in the extremities at the last follow up was performed on Enneking evaluation score with 6 categories. The highest scored 26, and the lowest scored 10, with an average of 19.5. A case in which the patient died 15 days after the operation was excluded from the evaluation. Among the categories, emotional acceptance to postoperative function and pain relief were highly scored. At the final follow up, seven patients survived, and one colon cancer patient died 68 days after operation. Conclusion: Metastatic tumor occurring in joints of lower extremities could be treated in accordance to the treatment principle of primary tumor. By insertion of tumor prosthesis, we can get satisfactory results of function in the lower extremity and pain relief especially. So, this aspect of medical favor must be considered in treating patients.

  • Minimal invasive surgery (MIS) has rapidly gained acceptance for the management of a wide variety of pediatric diseases. A questionnaire was sent to all members of the Korean Association of Pediatric Surgeons. Thirty one members (25.4%) took part in the survey that included data for the year 2012: demographic details, opinion regarding minimal invasive surgery and robotic surgery, spectrum of minimally invasive operations, and quantity of procedures. 48.4% of the respondents had more than 10 years experience, 35.5% less than 10 years experience, and 16.1 % had no experience. The respondents of the recommend MIS and perform MIS for surgical procedures are as follow; inguinal hernia (61.3%), simple appendicitis (87.1%), complicated appendicitis (80.6%), reduction of intussusceptions (83.9%), pyloromyotomy (90.3%), fundoplication (96.8%), biopsy and corrective surgery of Hirschsprung's disease (93.5%/90.3%), imperforate anus (77.4%), congenital diaphragmatic hernia (80.6%), and esophageal atresia (74.2%). The MIS procedures with more than 70% were lung resection (100%), cholecystectomy (100%), appendectomy (96.2%), ovarian torsion (86.7%), fundoplication (86.8%), hiatal hernia repair (82.6%), and splenectomy (71.4%). The MIS procedures with less than 30% were congenial diaphragmatic hernia reapir (29.6%), esophageal atresia (26.2%), correction of malroatation (24.4%), inguinal hernia repair (11.4%), anorectal malformation (6.8%), Kasai operation (3.6%).

  • Background: Lectins are proteins or glycoproteins of non-immune origin that recognize a specific sequence of sugar residues. The availability of a large number of lectins has provided the capacity to identify selectively glycoconjugates possessing distinctive chemical structure in diverse sites of highly specialized biological activity. The purpose of the present study was to investigate the lectin binding patterns of various components in human pulmonary tubercles. Method: Biopsy specimens of tuberculous lung were obtained from male adult patients who underwent a surgical resection for severe pulmonary tuberculosis. The specimens were processed and stained with 13 kinds of biotinylated lectins according to some modification of Hsu and Raine's methods. Results: 1) In the caseous necrotic lesions, BS $I-B_4$ showed negative reaction and BS I were also negative except some irregularly-shaped cells located in the marginal zone. All other lectins, however, showed a positive reaction with various binding patterns. 2) The epithelioid cells were broadly divided into three groups according to the reaction patterns in the cytoplasms and cell membranes. 3) WGA, ECL, PHA-L, PHA-E and LCA showed strong staining in the lymphocytes. 4) SBA showed a different binding patterns between the endothelial layers located in the region beyond the fibrous layers and those located within the fibrous layers. 5) PNA showed a positive reaction in the outer 1/3 to 1/2 of the fibrous layer, but showed no staining in the inner 1/2 to 2/3 of the fibrous layers. Conclusion: The present lectin histochemical study provided a useful information to assess the characterization and distribution of various glycoconjugates in each constituent of human pulmonary tubercles. The results demonstrate structural differences in the glycoconjugate composition of various components of the tubercles and reveal changes in glycosylation in the components during soft tubercle formation. This study provides a new data useful for the studies on the pathogenesis and pathology of human pulmonary tubercles.
