PURPOSE: The aim of this study is to evaluate the value of pleural adenosine deaminase (ADA) in differentiating tuberculous pleural effusion from non tuberculous pleural effusion of children. METHODS: We measured pleural ADA activity in patients with pleural effusion whose age were from seven months to seventeen years from January 1995 to October 2001. By some criteria the patients were grouped to tuberculous pleural effusion, bacterial effusion, mycoplasma effusion, malignant effusion, and other effusion. RESULTS: The mean pleural ADA activity in tuberculous pleural effusion was 86.2+/-27.3 U/L. Pleural ADA activities in bacterial effusion, mycoplasma effusion, malignant effusion, other effusion were 32.6+/-20.1, 22.1+/-15.4, 23.1+/-10.9, 36.7+/-28.4 U/L, respectively. Pleural ADA activity in tuberculous pleural effusion was significantly higher than in any other group(P<0.001). At a level of 50 U/L, the sensitivity, specificity, positive predictive value (ppv), and and negative predictive value(npv) for the identification of tuberculous pleural effusion from nontuberculous pleural effusion were calculated at 93.8%, 84.8%, 81.1%, 95.1%, respectively. CONCLUSION: Pleural ADA is a useful test in the diagnosis of tuberculous pleural effusion of children from nontuberculous pleural effusion.

PURPOSE: To evaluate the diagnostic accuracy of MR imaging in posterior cruciate ligament(PCL) injuries, to describe the variety of these injuries and to assess the type and frequency of associated knee injuries. MATERIALS AND METHODS: We retrospetively analysed 75 cases with knee injuries. In all cases, the prescence of a PCL tear was determined by arthroscopy or surgery and the type of tear and patterns of associated knee injuries were described. RESULTS: Twenty-eight PCL tears were identified with arthroscopy or surgery. Figures for the sensitivity, specificity, and accuracy of MR diagnosis for the PCL injury were 86%, 94% and 91% respectively. Twenty-one cases(75%) had complete PCL tears and seven (25%) had partial tears. The commonest tear site was midsubstance(18 cases, 64.3%). Twenty-seven cases(96%) had associated knee injuries ; the remaining patient(4%) had isolated PCL injuries. There were 19 cases(68%) of ligamentous injuries, ten (36%) of meniscal tear, ten (36%)of bony injuries, and 20 (71%) of joint effusions. Of the ligamentous injuries, those involving the medialcollateral ligament were most often seen(10 cases, 36%). CONCLUSIONS: MR imaging is an accurate method for the detection and evaluation of PCL injury and associated knee abnormalities.

Background: The goal of this study was to confirm the relationship between subjective body shape perception and the depression screening tool Patient Health Questionnaire-9 (PHQ-9) in the geriatric population. Methods: A total of 1,251 subjects were analyzed among adults aged 65 or older who performed the 2020 Korean National Health and Nutrition Examination Survey. The subjective body shape perception was divided into three groups (thin, normal, and obese). Depression screening tool PHQ-9 10 points were employed as a cut-off value. The association between subjective body shape perception and the risk of depression based on the PHQ-9 was first verified by achi-square test, and then logistic regression analysis was performed along with items expected to influence the relationship. Results: There was a considerable difference between the depression risk and the normal groups in subjective body shape perception, which was classified as thin, normal, and obese. In the final model, the group who thought they were thin had an increased risk of depression compared with the normal group. Dyslipidemia, being female, and not owning a home have all been demonstrated to greatly raise the risk of depression. Conclusion We verified that subjective body shape was related to the risk of depression through the PHQ-9.

Dialysis-related amyloidosis is a complication of long-term hemodialysis and it is characterized by the accumulation of beta2-microglobulin in the osteoarticular structures. We describe here the imaging findings of a case of dialysis-related amyloidosis involving the hip and cervical spine in a 62-year-old woman who received long-term dialysis. We focus here on the CT and MR imaging findings of the cervical spine and we include a review of the relevant literatures.

PURPOSE: Heptaplatin (SKI-2053 R) is a new platinum analogue, with a better toxicity profile than cisplatin, and has antitumor activity even in cisplatin resistant cell lines. 5-fluoruracil (5-FU) has shown synergy with platinum compounds. This phase II trial was designed to determine the efficacy and toxicities of heptaplatin/ 5-FU (5-fluorouracil) for treating stomach cancer. MATERIALS AND METHODS: Thirty-two patients with advanced, measurable gastric adenocarcinomas were enrolled in this trial. The treatment consisted of heptaplatin, 400 mg/m2/day (1 hour IV infusion), on day 1 and 5-FU, 800 mg/m2/day (12 hours IV infusion), on days 1 to 5. The cycles were repeated every 3 weeks. RESULTS: Of the 26 evaluable patients, 9 had partial responses and 1a complete response (overall response rate, 38%; 95% confidence interval, 19~57%). The median response duration was 23 weeks (range: 4~60 weeks). The median time to progression was 26 weeks (range: 3~68 weeks). The grades III-IV toxicities were mostly hematological toxicities: leucopenia was observed in 11 patients (35%) and thrombocytopenia 4 (13%). No definite neuropathy was observed. Grade I-II nephropathy was also noted: grade I high BUN/creatinine levels occurred in 5 patients (16%), grade II proteinuria 2 (6%), grade I proteinuria 5 (16%). Neutropenic fever developed in 5 patients (16%) and 1 died of pneumonia in a neutropenic state. CONCLUSION: This study suggests that the regimen of Heptaplatin/5-FU should be effective and have a favorable toxicity profile for the patients suffering with advanced stomach cancer.

Day-to-day insulin requirements often change due to subtle variations in insulin metabolism in patients with type 2 diabetes undergoing hemodialysis. In such cases, intra-hemodialysis hypoglycemia frequently occurs and is a main factor interfering with the delivery of dialysis. As a result, it reduces the quality of life in patients undergoing hemodialysis. The long-acting insulin analogue glargine provides peakless, continuous release over 24 h that approximates a normal basal insulin pattern. Because it has no peak, its use in patients with diabetes undergoing hemodialysis would hypothetically be useful. Specifically, patients would be able to avoid intra-hemodialysis hypoglycemia without the necessity of skipping insulin administration on the day of hemodialysis and achieving adequate glucose control on other days. We recently experienced six cases that switched from treatment with intermediate-acting insulin to a long-acting insulin analogue, which provided better glycemic control by reducing hypoglycemia risk. Limited data are available in the literature concerning insulin analogue usage in patients with diabetes undergoing hemodialysis. Our experience suggests a large-scale prospective investigation is required on this issue.

BACKGROUND: Thymidine phosphorylase (TP) is an enzyme catalyzing the reversible phosphorolysis of thymidine to thymine and 2-deoxyribose-1-phosphate. TP plays a role in angiogenesis. Evidences suggest that infiltrating inflammatory cells adjacent cancer cells may affect tumor cell behavior. To evaluate each of these significances of TP expression in cancer cell and cancer-infiltrating inflammatory cells, we investigated TP expression patterns in cancer cells and infiltrating inflammatory cells adjacent cancer cells separately and the relationship between TP expression and angiogenesis or survival. METHODS: Immunohistochemistry assays were performed with anti-TP monoclonal antibody (Roche Japan) and anti-factor VIII polyclonal antibody (Dako) on 92 paraffin-embedded tissue samples from stomach cancer patients. A single pathologist scored the slides for percent positivity of tumor cells, intensity, localization and distribution of expression. TP reactivity in tumor cells (cancer) and infiltrating mononuclear cells adjacent cancer cells (matrix) was separately accessed. According to the pattern of TP expression, subjects were divided into 4 groups for further analysis: cancer(C;+)/matrix(M;+), cancer(+)/matrix(-), cancer(-)/matrix(+) and cancer(-)/matrix(-). With these 4 subsets of TP expression patterns, we evaluated cancer cell differentiation, intratumoral microvessel density, extent of tumor invasion, LN stage, and patient survival to find any differences among the subsets. RESULTS: Of 92 stomach cancer tissue, C/M(+/+), C/M(+/-), C/M(-/+), and C/M(-/-) were observed in 33patients, 19, 30, and 10, respectively. Microvessel density scores were higher in cancer(+)/matrix(-) group compared in cancer(-)/matrix(-) group (p=0.02). Of 4 TP expression subsets, other clinical factors such as histology, extent of tumor invasion, and LN metastasis were not associated with TP expression. CONCLUSION: This study suggested the TP in cancer-infiltrating inflammatory cell as well as cancer cells themselves may play an important role in angiogenesis as co-active factors in stomach cancer.

Thymidine phosphorylase (TP) has shown to be up-regulated in several cancers and to play a role in angiogenesis and invasion. Most studies regarding TP have focused on cancer cells. Recently, evidences suggest that TP in cancer-infiltrating inflammatory cells (CIICs) also affect the cancer cell behavior. To evaluate the significance of TP expression of CIICs in gastric cancer, we assessed TP expression of cancer cells and CIICs separately using immunohistochemical assay on 116 paraffin-embedded tissue samples from stomach cancer patients and investigated their clinical significance. When subjects were divided into 4 groups according to the TP expression: cancer/matrix (+/+), C/M (+/-), C/M (-/+), and C/M (-/-), intratumoral microvessel density scores were higher in the C/M (+/-) group than in the C/M (-/-) group (p=0.02). For lymph node metastasis and survival, there were no significant differences among the 4 groups. However, there were significant differences in survival (p=0.035) and LN metastasis (p=0.023) between the two groups divided by TP expression of CIICs alone irrespective of TP expression of cancer cells. Taken together, this study suggested the TP expression in CIICs could affect lymph node metastasis and patients' survival in gastric cancer.

Complete circulatory arrest with profound hypothermia has been an indispensable adjunct to the safe management of selected giant intracranial aneurysms. For the conduct of cardiopulmonary bypass, there are usually two kinds of methods, open and closed chest methods. We could manage one case of huge intracranial aneurysm that was successfully operated under circulatory arrest using the closed chest method, especially with percutaneous insertion of arterial and venous cannulas for cardiopulmonary bypass.
