Eleven cases of arthroscopic ankle arthrodesis were reviewed. Average age of patients was 59 years, 4 male and 7 female. Underlying diseases were osteoarthritis in 7 cases, rheumatoid arthritis in 3 cases and one post-traumatic arthritis. At the mean follow up of 15 months, fusion rate was 100%, mean time to complete union was 9.5 weeks. There were no complications such as nonunion, infection and skin problems. All patients stayed at the hospital just overnight after the surgery. Patients satisfaction was high and the functional clinical grade was excellent in 9 patients, good in 1 patient and fair in 1 patient. We concluded that arthroscopic technique was a simple and effective method for ankle arthrodesis in the selected patients and had significant advantages over the open technique.

Breast cancers that present with mucin include mucinous carcinoma and carcinoma with signet ring cell differentiation. The former shows extracellular mucin and the latter shows abundant intracellular mucin. Here, we report a case of breast cancer showing both extracellular mucin and extensive signet ring cell differentiation due to abundant intracellular mucin. Unlike mucinous carcinoma, this case had the features of high-grade nuclear pleomorphism, high mitotic index, estrogen receptor negativity, progesterone receptor negativity, human epidermal growth factor receptor-2 positivity, and ductal type with positivity for E-cadherin. In a case with signet ring cell differentiation, differential diagnosis with metastatic signet ring cell carcinoma of the stomach and colon is essential. In this case, the presence of accompanied ductal carcinoma in situ component and mammaglobin and gross cystic disease fluid protein-15 positivity were findings that suggested the breast as the origin.

Most foreign bodies in the lower genitourinary tract are self-inserted through the urethra for masturbation. It can be diagnosed by clinical histories and physical examinations of the patient, endoscopy and radiologic evaluations. Extraction should be tailored as the surgery, endoscopic manipulation and dissolution according to the nature of the foreign body and should minimize bladder and urethral injury. We report a case of a long wire in the bladder and urethra with brief review of literatures.

Inflammatory pseudotumors are infrequently occurring lesions, characterized by a localized mass composed of a benign proliferation of inflammatory cells, with varying amount of fibrosis. As a type of inflammatory pseudotumer, eosinophilic cholangitis or eosinophilic pseudotumor are extremely rare, and characterized by eosinophilic cholecystitis and associated extrahepatic biliary obstruction. Herein, we report a case of an eosinophilic pseudotumor of the bile duct in a 37-year old man who was referred to Eulji University Hospital for evaluation of jaundice. From cholangiography and a CT scan, intrahepatic duct dilatation and common hepatic duct obstruction were detected, therefore, common hepatic duct cancer was suspected. After percutaneous biliary drainage, he underwent an operation for bile duct resection and a hepaticojejunostomy. The final pathological finding was that of cholecystitis, with eosinophil and wall thickening of bile duct, accompanied by eosinophil infiltration and fibrosis, which was compatible with eosinophilic pseudotumor. The patient had no subsequent remarkable postoperative course and was discharged with normal liver function.

BACKGROUND: Surgical resection offers the potential care in patients with carcinoma of the lung whose tumors are amenable to resection, those with infections destroyed lung discase or congenital lung disease prediction of risk factors to influencing outcome after thoracic operations offers important benefits. Physicians anticipating those patients most prone to complications can provide special attention aimed at reducing morbidity and mortality. MATERIAL AND METHOD: We have retrospectively reviewed hospital records of 153 patients undergoing pulmonary resection for neoplastic and inflammatory destroyed lung disease between 1994 and 1998 to identify predictors of outcome. The mean age was 54.3+/-10.6years. Ninety-six patients(62%) had malignant lung disease and 47 patients(30%) had destroyed lung desease and 10(7%) had congenital or other lung desease. RESULT: Of the 153 resections performed 118 were lobectomies, 29 were pneumonectomies, 6 were segmentectomies, Seven of the 153 patients died during their hospital stay(4.5%). The most significant predietors of in-hospital mortality were presence of concomittent medical disease (P<0.001) and patients age 70 years or over(P<0.003). There were 67 postoperative complication occurring in 57 patients. Operation related complications were in 50 patients (32%), respiration related were in 14(9.1%) and cardiovascular related were in 1(0.6%) and other complications were in 2 patients(1.3%). The most significant predictors of postoperative morbidity was patients age 70 years or over(P<0.004). CONCLUSION: concomitant medical disease and patients age 70 years or over were very predictive value of postoperative mortality, also the patients age 70 years or over was significant preoperative value of postoperative morbidity.

In this paper, we present some results from an experimental web-based Problem-Based Learning(PBL) course, which was offered to 64 medical students in the first grade at Konkuk university for 7 weeks. For the course, we developed a web-based PBL module, which is composed of three sections. The first section includes the 8 stages of problem probing and solving in patient's care. In every stage, the students can browse all the data for the problem solving. The second section contains some problems for evaluating the academic achievement of the students who successfully passed in the first section. In the third section, some questionnaires are presented to survey the students response. The followings are the results. 1. Average score of the first section was 64.1+/-13.2. Most students participated in the course with integrity, and especially seven students(11%) were remarkable in their clinical reasoning. 2.The student's computer skill did not largely affect their academic achievements. However, it is desirable for the students to learn basic computer usage in advance. 3.A few students attended to the discussion through bulletin board facilities. Considering the importance of discussion in PBL, we need to devise a new way of attracting students in the discussion. 4. The survey showed that sixty five percent of the students thought that the lecture was effective and ninety one percent of them that it would be better if it is offered as a regular course during summer or winter vacations. Seventy five percent of students became to realize the importance of basic sciences such as biochemistry and physiology after this course. 5. There were many students who complained about the malfunctioning of the system. The system should be modified to be more reliable and robust. In conclusion, the web-based PBL course provided an effective way of learning in medical education. It also turned out to be used as an alternative of traditional PBL and especially useful for self study.

PURPOSE: Minimal Change Nephrotic Syndrome (MCNS) is one of the most common primary nephrotic syndromes in children. T-cell dysfunction has been thought to be involved in the pathogenesis of MCNS. However, the exact pathogenesis of MCNS has not been proven yet in spite of many studies which support T-cell dysfunction being involved in the pathogenesis of MCNS. A present study was done to determine the role of IL-8 and TNF-alpha in the pathogenesis of MCNS. METHODS: Study patients consisted of 19 biopsy-proven MCNS children aged 2-15 years old. Ten age-matched healthy children were used as controls. Both plasma and urinary IL-8 and TNF-alpha were measured during relapse and remission period using ELISA kit. Urinary cytokine values were corrected for urinary creatinine. RESULTS: Each value of urinary IL-8 measured during relapse and remission period in MCNS and controls was 13,996+/-2,811, 2,811+/-3,734 and 5,331+/-6,403ng/mg cr, respectively, and we noted that the value of urinary IL-8 measured during relapse period in MCNS significantly increased compared to those measured during remission period and in controls(p< 0.05). And each value of urinary TNF-alpha measured in the same group was 364.4+/-512.1, 55.3+/-208.0 and 36.0+/-45.0ng/mg cr, respectively, and we also noted that the value of urinary TNF-alpha measured during relapse period in MCNS was signficantly increased compared to those measured during remission period and in controls. The plasma cytokine values measured during relapse and remission period and in controls were 1.19+/-1.23, 0.51+/-0.84 and 0.77+/-0.62ng/mL, respectively, in the case of IL-8 and 2.42+/-3.86, 1.95+/-3.24 and 2.25+/-3.50ng/mL, respectively, in the case of TNF-alpha, and we noted the value of plasma IL-8 measured during relpase was also significantly increased compared to those of remission period and in control(p<0.05), but the change of plasma TNF-alpha values was not significant. CONCLUSION: It can be said that both IL-8 and TNF-alpha play an important role in the pathogenesis of MCNS in children. The fact that changes of urinary IL-8 and TNF-alpha were more prominent than those of plasma suggests that immune dysregulation may occur intrarenally rather than systemically in MCNS.
