Syringomyelia can occur as a complication of tuberculous meningitis despite of appropriate chemotherapy and almost it is founded with motor and sensory disturbances. We have experienced a case of an extensive syringomyelia & syringobulbia in tuberculous meningitis who complained only mild numbness & diplopia without specific motor disturbance. So we think that we should not overlook even mild symptoms and have to evaluate the syringomyelia timely by radiographic study.

PURPOSE: Currently, the role of liver transplantation in the treatment of hepatocellular carcinomas with cirrhosis is controversial due to the shortage of donors and to the high recurrence rate after transplantation. What remain to be determined are the best treatment protocol and who are likely to have a good outcome after liver transplantation. METHODS: Eight patients (all male, range 30 to 67 years) with a hepatocellular carcinoma underwent liver transplantation between 1993 and 1999 in Catholic University, Medical College. The criteria for exclusion of transplantation were extrahepatic tumor metastasis, positive regional lymph nodes, and tumor thrombus on the main portal trunk. All except one were treated with preoperative arterial chemoembolization alone or combined with chemotherapy or ethanol injection. The follow-up period was from 5 months to 27 months. The pathologic findings, the recurrence, and the survival rate were analyzed. RESULTS: One patient had a tumor, larger than 5 cm in diameter (5.9 cm) and another patient had 6 nodules in number. Vascular invasion was present in 3 patients. Among the 8 patients, postsurgical TNM staging was stage III in 3 patients and stage IVA in 2 patients. During the follow-up, 7 of the 8 patients (87.5%) survived, and the number of disease-free survivals was 6 among the 8 patients (75%). One patient died with recurrent hepatitis C 6 months after transplantation without tumor recurrence. The patient who had the largest tumor in size had recurrent cancer on the abdominal wall at 9 months after transplantation, and subsequent pulmonary recurrences at 15 and 19 months which were treated by resection. CONCLUSION: Hepatocellular carcinoma could be a good indication for liver transplantation in selected patient, but the best protocol remains to be determined, especially in large tumors.

Generally, regular exercise is known to help to improve lipid metabolism. In the spinal cord injured, relative inactivity to able-bodied person causes altered lipid profiles and, in turn, possibly increases cardiovascular mortality. We performed this study to measure serum lipid profiles in paraplegics and to evaluate effect of regular exercise on lipid profiles. The subjects are 21 paraplegics, who are divided into 2 groups, 10 SCI athletes and 11 SCI non-athletes. The serum levels of lipoproteins in these subjects were measured and compared each other. The levels of serum HDL-cholesterol were lower in the order of, non-athlete group, athelte group, and normal control group, and there was a significant difference between athlete and non-athlete groups. The ratios of total cholesterol to HDL-cholesterol were higher in the order of non-athlete group, athlete group, and normal control group, and there was a significant difference between control and non-athlete groups. The serum levels of total cholesterol, LDL-cholesterol, and triglyceride in three groups showed no significant differences. In conclusion, serum levels of HDL-cholesterol were positively affected by regular exercise, and it is advised that the HDL-cholesterol levels of spinal cord injured should be checked regularly for follow-up examinations.

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.

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.

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.

The use of human umbilical cord blood-derived mesenchymal stem cells for cell transplantation therapy holds great promise for repairing spinal cord injury. Here we report the first clinical trial transplantation of human umbilical cord (hUCB)-derived mesenchymal stem cells (MSCs) into the spinal cord of a dog suspected to have fibrocartilaginous embolic myelopathy (FCEM) and that experienced a loss of deep pain sensation. Locomotor functions improved following transplantation in a dog. Based on our findings, we suggest that transplantation of hUCB-derived MSCs will have beneficial therapeutic effects on FCEM patients lacking deep pain sensation.

BACKGROUND: The adhesion of H. pylori to the gastric epithelial cells may be an essential step for the pathophysiology of various H. pylori-induced gastrointestinal diseases. The purpose of this study was to investigate the ultrastructural relation of H. pylori and gastric epithelial cells in their adhesion. METHODS: Endoscopic biopsy of gastric antrum and body was performed from 15 patients (9 men, 6 women) with chronic gastritis and H. pylori infection. The specimens were processed for electron microscopy and observed with a transmission electron microscope (Hitachi H-600). RESULTS: On the basis of morphological appearances, the adhesions of H. pylori to the gastric epithelial cells were categorized into three types; filamentous connection, adhesion pedestals and membrane fusion. Coccoid and undetermined forms adhered mainly by the filamentous connection, whereas the bacillary forms adhered primarily by the adhesion pedestals and membrane fusion. CONCLUSION: Various types of adhesion were associated with H. pylori and gastric epithelium. Further studies are needed to evaluate the influence of different types of adhesion to the pathophysiology of H. pylori.

BACKGROUND/AIMS: Assessment of malignant potential in gastrointestinal stromal tumor (GIST) is still problematic. The maximum tumor diameter and the mitotic index are generally used as an index of malignancy of GISTs. The Ki-67 labeling index has recently been used as an index of cell growth. The aim of this study was to investigate the prognostic value of Ki-67 in GIST. METHODS: We retrospectively reviewed the medical records of 32 patients with GIST who underwent surgical resection at Inje University Seoul Paik Hospital. We analyzed their Ki-67 expression, histologic finding, and prognosis. RESULTS: According to the tumor size and mitotic count, 4 patients were classified as very low risk, 9 patients as low risk, 14 patients as intermediate risk and 5 patients as high risk. The average Ki-67 index was 5.56+/-4.48%. The median follow-up duration was 35.72+/-29.04 months, and local/distant recurrences were observed in 6 (18.7%) patients. The overall cumulative disease free survival rates in patients with Ki-67 index < or =5% at 1 year, 2 years, and 5 years were 100%, 100%, and 86%, respectively. The overall cumulative disease free survival rates in patients with Ki-67 index >5% were at 1 year, 2 years, and 5 years were 82.1%, 70.3%, and 46.9%, respectively. There was significant relationship between elevated Ki-67 and disease free survival rate (p=0.007). CONCLUSIONS: Our study suggests that Ki-67 index >5% confers a higher risk of relapse in patients with GIST. Future work should focus on standardization of Ki-67 assessment and specification of its role in making treatment decisions.
