In Systemic lupus erythematosus several correlations with anti-Ro antibodies have been noted. They are the increased incidence of photos nsitive skin disease, rheumatoid factor positivity, Sjogren's syndrorme, and a greatly increased incidence of the DR 3 hapIotype. In this study we examined the prevalence of anti-Ro anibodies(not concerned for anti-La, Sm, RNP) by double immunodiffusion method among thirty two Korean patients with systemic lupus erythematosus who had positive results on routine fluorescent antinuclear antibody test. We also have seen skin manifestations on these patients, and examined if there is any difference of the incidence for each skin sign between anti-Ro positive and negative subgroups. From the data obtained, the proportion of anti-Ro positives among these patients with systemic lupus erythematosus was 53% Regarding to the difference of the incidence of cutaneous rnanifestations between the two subgroups, the photosensitivity reaction was recongnized as a uniqu symptorn rnore prevalent (p<0. 05) in anti-Ro positive subgroup with the frequency of 65%.

Congenital dilatation of the common bile duct is relatively rare anomaly. Its pathogenesis has not been completely understood. Complications of the choledochal cyst are mainly suppurative cholangitis, liver cirrhosis, stone formation, malignant change, bile peritonitis due to spontaneous and traumatic rupture. We experienced one case of choledochal cyst associated with hemorrhagic tendency and a cerebral hematoma, which is extremely rare complication. The 3 months old male patient reported here was treated with complete excision of cyst and Roux-en-Y choledochojejunostomy after correction of bleeding tendency and removal of cerebral hematoma. Postoperative course was relatively uneventful. 11 days after operation, the patient was discharged with full improvement.

Granular cell tumor (GCT) of the breast is a rare clinical entity, and is believed to be of schwannian origin and to follow a benign clinical course. A 50-year-old woman presented with a slowly growing mass in the right breast. Fine needle aspiration cytology revealed a cellular smear containing isolated or clustered cells showing round to oval nuclei with abundant oncocytic granular cytoplasm. Nuclei showed a fine granular chromatin pattern and occasional small single nucleoli. Cell boundaries were poorly defined, and naked nuclei were frequently found. Histologically, the tumor showed features of typical GCT, and immunohistochemical staining findings strongly supported the diagnosis. The present study demonstrates that GCT of the breast can mimic malignant lesions of breast both clinically and radiologically. The recognition of its cytologic features and suspicion of this lesion would undoubtedly aid the correct diagnosis of mammary GCT.

Xanthogranuloma is a benign, fibrohistiocytic lesion that presents as a yellowish, cutaneous papule or nodule. Although the head, neck, and trunk are the most common sites for xanthogranuloma, it can appear at any site on the body. We report a rare solitary xanthogranuloma on the palm of 24-year-old man.

Cutaneous metastasis from bladder cancer is very rare. A 48-year-old man presented with a 5 month history of a dome-shaped nodule on his scalp. Histopathologic examination of the skin lesion revealed the proliferation of atypical cells, which were similar to those of urothelial carcinoma of the urinary bladder. We herein report on a case of cutaneous metastasis from urothelial carcinoma of the urinary bladder with a review of the Korean literature.

We induced percutaneous spinal cord injuries (SCI) using a balloon catheter in 45 rats and transplanted human umbilical cord blood derived mesenchymal stem cells (hUCB-MSCs) at the injury site. Locomotor function was significantly improved in hUCB-MSCs transplanted groups. Quantitative ELISA of extract from entire injured spinal cord showed increased expression of brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF) and neurotrophin-3 (NT-3). Our results show that treatment of SCI with hUCB-MSCs can improve locomotor functions, and suggest that increased levels of BDNF, NGF and NT-3 in the injured spinal cord were the main therapeutic effect.

Here, percutaneous spinal cord injury (SCI) methods using a balloon catheter in adult rats are described. A balloon catheter was inserted into the epidural space through the lumbosacral junction and then inflated between T9-T10 for 10min under fluoroscopic guidance. Animals were divided into three groups with respect to inflation volume: 20 microL (n = 18), 50 microL (n = 18) and control (Fogarty catheter inserted but not inflated; n = 10). Neurological assessments were then made based on BBB score, magnetic resonance imaging and histopathology. Both inflation volumes produced complete paralysis. Gradual recovery of motor function occurred when 20 microL was used, but not after 50 microL was applied. In the 50 microL group, all gray and white matter was lost from the center of the lesion. In addition, supramaximal damage was noted, which likely prevented spontaneous recovery. This percutaneous spinal cord compression injury model is simple, rapid with high reproducibility and the potential to serve as a useful tool for investigation of pathophysiology and possible protective treatments of SCI in vivo.

OBJECTIVE: Although the therapeutic outcome of aggressive non-Hodgkin's lymphoma (NHL) has been considerably improved by the introduction of combination chemotherapy, many patients still fail to achieve complete response(CR) and/or long-term survival. Because the outcome appears to depend on certain prognostic factors, long term prognosis can be predicted by identification of risk group. And also, the patients in high risk group may benefit from new therapeutic modality. In 1993, the international prognostic index model for aggressive NHL as developed far the purpose of predicting outcome and designing of therapeutic trial. Thus, analysis of prognostic factors was performed to identify independent factors for the end points of CR, overall survival, and disease-free survival. METHODS: From 1989 to 1994, total 340 patients were treated with combination chemotherapy and/or radiotherapy for NHL in Korea Cancer Center Hospital. Among 340, informations on eleven prognostic factors(sex, age, performance status, Ann Arbor stage, serum LDH level, tumor size, number of extranodal disease sites, bone marrow involvement, presence of B symptom, sex, time to CR, and histologic grade) were avaliable for 273 patients. Among these, 221 patients with aggressive NHL(NCI clinical schema) were eligible for the prognostic factor analysis for the response and survival. Also, 186 patients were eligible to determine whether International Prognostic Index Model could be applicable for Korean NHL. RESULTS: One hundred fifty patients(68%, 95% CI 62-74%) achieved a complete remission, 43 patients (20%) a partial remission. With a median follow-up of 3,5 years, overall 3 year survival rate was 6396, and 3 year DFS for the 150 CRs was 72%. In a univariate analysis for the CR and survival, Ann Arbor stage, number of extranadal disease, performance status, presence of B symptoms, presence of BM involvement, serum LDH level and histologic grade were found to be statistically significant prognostic factors. Among them, by multivariate analysis, number of extranodal disease(RR 0.2, 95% CI 0.1-0.7), B Symptoms (RR 0.4, 95% CI 0.2-0.9), and histologic grade(RR 0.2, 95% CI 0.08-0.7) showed to be independent adverse prognostic factors for CR. For disease-free survival, Ann Arbor stage(RR 2.6, 95% CI 1.1-6.4) was independent risk factor. For overall survival, number of extranodal involvement(RR 2, 95% CI 1.3-4) and histologic grade(RR 2, 95% CI 1.2-3.7) were independently significant prognostic factors. With these 2 independent prognostic factors for survival, we could establish a prognastic index model which could separate the high risk patients. However, the usefulness of this model should be confirmed in a larger patient population. The dose intensity of cyclophosphamide, during initial 3 months of treatment, was significantly associated with CR rate and overall survival(p=0.01 and 0.03, respectively). When International Prognostic Index Model was applied to our patients, patients in the lower risk groups had significantly better outcome than patients in the higher risk groups(3 year survival and RR: 77% and 1 for low risk group, 61% and 1.9 for low-intermediate risk group, 50% and 2.2 for high-intermediate risk group, and 25% and 6 for high risk group). CONCLUSION: In this study, we confirmed that features other than the Ann Arbor stage were independently associated with CR and survival, and the International Prognostic Index Model would be an useful tool for the selection of high-risk patients who could be benefited from more aggressive chemotherapy.

PURPOSE: Primary central nervous system lymphoma (PCNSL) is defined as lymphoma limited to the cranial-spinal axis without evidence of systemic disease and its incidence has risen threefold during the last fifteen years among apparantly healthy population. This study was intended to analyze the clinicopathologic features and treatment outcome of the patient with PCNSL. MATERIALS AND METHODS: Twenty one patients were diagnosed and treated for the PCNSL limited to brain parenchyme at Asan Medical Center between March 1989 and December 1996. We reviewed clinical records of these patients and analyzed clinicopathologic features, treatment response, survival time and prognostic factors. RESULTS: The ratio of male to female was 1.3: 1 and the most prevalent age group was the 4th decade. Most patients had diffuse large cell (19/21) and B-cell type (8/8). Seventeen (94.4%) among 18 evaluable patients achieved complete remission (CR) as initial response, but 53% of patients showed recurence of the disease. Median times of disease-free and overall survival were 40 and 50 months, respectively and 5 year overall survival rate was 35.3 %. Prognostic factors such as age and performance status, had a statistically significant influence on the overall survival but not on disease-free survival. CONCLUSION: CR rate of the patients with PCNSL was high, but relapses were frequent. There fore further studies are needed to define the pmgnostic factors and to decrease relapse rate.
