Only a few cases of cyst related to cruciate ligament were reported in the literatrure. It is not only because of rarity but also difficulty of diagnosis by conventional method. Recentely, the precise intraarticular structure of the knee joint became to be seen by introduction of MRI and arthroscope and cycts would bave been found incidentally during the workup of the internal derangement of knee. We have experienced three cases of ganglion around the cruciate ligament in the patients whose symptom was mimic of intemal derangement of knee. We excised the ganglion with good clinical results.

BACKGROUND AND OBJECTIVES: The transradial approach for coronary intervention has a lower incidence of access site complications and can increase patient comfort after percutaneus tansluminal coronary angioplasty(PTCA). The purpose of this study is to compare procedural success and complication rates of percutaneous transradial coronary stenting which was performed by four operators in two hospitals with those using transfemoral approach. MATERIALS AND METHOD: From September 1998 to July 1999, one hundred seventy five consecutive patients(201 lesions) treated with coronary stent implantation were enrolled for this study : 84 patients underwent transradial coronary stenting(Radial Group), and 91 patients transfemoral coronary stenting(Femoral Group). RESULTS: Seven patients who failed coronary cannulation via radial artery were crossed over to the Femoral Group. The measurements of the radial artery were not done. Patient demographics were similar in both groups. Procedural success was similar in both group(95.2% in Radial Group vs. 97.8% in Femoral Group, p=S). All transradial coronary stenting were possible using conventional guiding catheters which are used in transfemoral intervention. Local vascular complication rates showed a trend toward a reduction in the Radial Group(2.4% vs. 8.8%, p=.06). CONCLUSION: This study showed the similarity in the safety and efficacy of transradial coronary stenting compared to those of transfemoral approach.

BACKGROUND: Introduction of calcineurin inhibitor (CNI) has markedly improved the outcome of kidney transplantation. While therapeutic drug monitoring is used to adjust the dosage of CNI, some patients, particularly children, still suffer from rejection, infection, and CNI toxicity. This study was conducted in order to assess the adequacy of immunosuppression using pharmacodynamic monitoring. METHODS: Pharmacodynamic monitoring was performed for 64 pediatric kidney allograft recipients. Expression of nuclear factor of activated T lymphocytes (NFAT)-regulated genes in patients' mononuclear cells was measured by quantitative polymerase chain reaction of interleukin-2, interferon-gamma (IFN-gamma), and granulocyte-macrophage colony stimulating-factor before (trough) and 1.5 hour (peak) after ingestion of tacrolimus and the residual gene expression (RGE) was calculated. Global immune response was assessed by Cylex-ImmuKnow assay. Trough and peak levels of tacrolimus were measured and clinical findings of rejection episodes and infectious complications were reviewed retrospectively. RESULTS: Global immune response measured byImmuKnow did not show correlation with trough and peak levels of tacrolimus. Adenosine triphosphate level of ImmuKnow was higher in patients with Epstein-Barr virus (EBV) infection than in those without infectious complications (515.4+/-149.0 ng/mL vs. 342.7+/-155.3 ng/mL, P=0.006). Mean RGE of the three NFAT-regulated genes showed negative correlation with tacrolimus peak levels. RGE of IFN-gamma was lower in patients with other infections except EBV than in those without infectious complications (34.0%+/-7.5% vs. 56.0%+/-30.2%, P <0.001). CONCLUSIONS: RGE of NFAT-regulated genes and ImmuKnow did not show significant correlation with clinical manifestation of under- or over-suppression of immune function in pediatric kidney allograft recipients. Further studies are required for development of optimal pharmacodynamic monitoring for pediatric kidney transplantation recipients.

Rituximab, a chimeric anti-CD20 IgG1 monoclonal antibody, has been used as a rescue therapy for steroid-dependent or refractory nephrotic syndrome. However, the adverse effects of rituximab are yet to be investigated. We report a case of a 9-year-old boy with steroid-dependent nephrotic syndrome who developed Kikuchi-Fujimoto disease after several cycles of rituximab therapy. Kikuchi-Fujimoto disease is a benign, self-limited necrotizing histiocytic lymphadenitis of unknown etiology. In the present case, Kikuchi-Fujimoto disease developed when the peripheral blood B-cell count of the patient was at nadir, and the lesion regressed slowly but spontaneously after recovery of the B-cell count. To our knowledge, although the pathologic diagnosis of Kikuchi-Fujimoto disease was unavailable, this is the first report of Kikuchi-Fujimoto disease with clinical diagnosis as a possible adverse effect of rituximab.

Ki-1 positive anaplastic large cell lymphoma is a newly described high-grade lymphoma and is defined by histopathological and immunologic criteria. We experienced a case of systemically involving Ki-1 positive anaplastic large cell lymphoma in a 44 year- old female which initially manifested as pleural effusion. Abdominopelvic CT scan showed the evidence of marked lymphadenopathy in retroperitoneal and both external and inguinal lymph nodes. On cytologic examination of pleural fluid, tumor cells revealed pleomorphic large isolated cells with prominent nucleoli and abundant cytoplasms. The nuclei were large with irregular profiles including some deep invaginations. Also, occasional multilobed/ multinucleated and binucleated nuclei were seen. Immunohistochemical examination was performed to differentiate from the undifferentiated adenocarcinoma, Hodgkin's disease, non-Hodgkin's lymphoma and malignant histiocytosis. The neoplastic cells were positive for leukocyte common antigen, CD3, CD30(Ki-1) but negative for cytokeratin, epithelial membrane antigen, and CD15. A histologic diagnosis of Ki-1 positive anaplastic lymphoma was made by biopsies of the inguinal lymph node, polypoid lesions of the stomach and cecum.

Chyluria is the passage of milky urine due to the leakage of lymph into the urinary tract. Chyluria occurs predominantly in adults and is rare in children. We present an unusual case in which a child with proteinuria, hematuria and milky urine was subsequently diagnosed with non-parasitic chyluria. Retrograde cystogram confirmed a lymphatico-calyceal communication. This case showed spontaneous remission. The etiology of this case was not exactly known; however, the prognosis of non-parasitic chyluria (or idiopathic chyluria) is usually very good and the treatment is mostly conservative.

PURPOSE: The present study aimed to evaluate the accuracy of determining the prevalence of atopic dermatitis (AD) with a questionnaire by diagnosing AD with both a questionnaire and pediatricians' physical examinations and to determine the possible risk factors for AD. METHODS: A survey was conducted from December 2008 to February 2009 in four elementary schools. The Korean version of the International Study of Asthma and Allergies in Childhood written questionnaire (WQ) was used to identify AD ever and AD during the last 12 months. Current AD was diagnosed by well-trained pediatricians according to the Hanifin and Rajka's diagnostic criteria. A total of 2,729 children who completed the questionnaire and underwent a physical examination by pediatricians were included in this analysis. RESULTS: According to the WQ, the prevalence of AD in the entire life and in the last 12 months was 18.4% and 12.9%, respectively. The prevalence of clinically diagnosed AD by pediatricians was 8.8%. There was a significant positive relationship between the prevalence of AD diagnosed by physical examination and past history of allergic rhinitis (adjusted odds ratio [aOR], 1.45), allergy history of the mother (aOR, 2.48), and AD history of the mother (aOR, 1.61). According to the WQ, there was also a significant positive relationship between the prevalence of AD in the last 12 months and past history of asthma (aOR, 2.55) and AD history of the mother (aOR, 1.71). CONCLUSION: Prevalence and risk factors of AD were different according to the survey methods. When prevalence of AD is determined with a questionnaire in the future, more careful attention should be used, because the result can be overestimated compared to the actual prevalence.

An application of the multi-detector computed tomography (MDCT) for cardiac imaging is the non-invasive CT angiographic assessment of the cardiac morphology and the coronary arteries. The most important application is for the non-invasive diagnosis of coronary artery disease, and this includes assessment of coronary artery anomaly and stenosis, the evaluation of non-calcified atherosclerotic plaque and the follow-up examinations after stent deployment and bypass surgery. In the study, we have illustrated a variety of diseases of the coronay artery by using MDCT. These may facilitate the understanding of MDCT features of coronary artery lesions.
