OBJECTIVE: To evaluate the diagnostic value of computed tomography-myelography (CTM) compared to that of magnetic resonance imaging (MRI) in patients with lumbar radiculopathy. METHODS: The study included 91 patients presenting with radicular leg pain caused by herniated nucleus pulposus or lateral recess stenosis in the lumbar spine. The degree of nerve root compression on MRI and CTM was classified into four grades. The results of each imaging modality as assessed by two different observers were compared. Visual analog scale score for pain and electromyography result were the clinical parameters used to evaluate the relationships between clinical features and nerve root compression grades on both MRI and CTM. These relationships were quantified by calculating the receiver-operating characteristic curves, and the degree of relationship was compared between MRI and CTM. RESULTS: McNemar's test revealed that the two diagnostic modalities did not show diagnostic concurrence (p<0.0001). Electromyography results did not correlate with grades on either MRI or CTM. The visual analog pain scale score results were correlated better with changes of the grades on CTM than those on MRI (p=0.0007). CONCLUSION: The present study demonstrates that CTM could better define the pathology of degenerative lumbar spine diseases with radiculopathy than MRI. CTM can be considered as a useful confirmative diagnostic tool when the exact cause of radicular pain in a patient with lumbar radiculopathy cannot be identified by using MRI. However, the invasiveness and potential complications of CTM are still considered to be pending questions to settle.

BACKGROUND: Thyroid status in uremia is still inconclusive due to the complexicity of the system. No single pathogenetic event may explain the thyroid function abnormalities in end stage renal disease (ESRD). Defects at all levels of the hypothalamic-pituitary-thyroid axis have been identified. Regarding the thyroid dysfunction in ESRD it is well recognized that the TSH response to TRH is blunted and serum concentrations of thyroid hormones are decreased in patients with ESRD. Whether or not on maintenance hemodialysis. Restoration of renal function with renal transplantation resulted in normalization of all parameters of thyroid function with exception of blunted TSH response to TRH. We evaluated the long-term changes of the thyroid function in 10 patients to know whether the thyroid function and the hypothalamo-pituitary axis were improved with the recovery of the renal function under maintenance low-dosage steroid administration after renal transplantation. METHODS: These tests were performed during the morning in the fasting state in 10 ESRD patients before, 1 month and 6 years after renal transplantation (RT). Thyroid function tests. Serum T3, T4 were measured by RIA kit and serum TSH was measured by IRMA kit. TRH stimulation test. Serum blood samples were obtained 0, 30, 60, 90, 120 min after TRH (400microgram) administration. Statistical analysis. All grouped data were expressed as mean+/-SD. Student t-test was used to assess the statistical difference between any two means. RESULTS: 1) The mean basal level of serum T3 was reduced in ESRD patients (53.6+/-33.2ng/dL) and increased to the low normal level 1 month after RT (87.8+/-25.4ng/dL), improved to the normal level 6 years after RT (116.3+/-28.8ng/dL). 2) The mean basal level of T4 was within normal range before RT (5.9+/-1.1microgram/dL), after 1 month (6.2+/-1.2microgram/dL) and after 6 years (6.5+/-1.4microgram/dL) of RT. 3) The mean basal level of TSH was within normal range before RT (2.0+/-1.2microU/mL), after 1 month (1.1+/-0.7microU/mL), and after 6 years (0.7+/-0.5microU/mL) of RT. Rut the mean TSH level of 6 years of RT was significantly decreased within the normal range. 4) In ESRD the TSH response to TRH was blunted, had a diminished peak and delayed fall before RT. After 1 month of RT, the TSH response to TRH was persistently blunted, however showed more rapid fall of TSH. After 6 years of RT, the TSH response to TRH normalized, but the absolute level of TSH and the peak level of TSH to TRH were less than before and after 1 month of RT. CONCLUSIONS: The abnormalities of thyroid hormones in uremic patients were improved partially after 1 month of RT and almost completely after 6 years of RT. But the level of T3H and the peak level of TSH to TRH were low within normal range, these results may be a direct consequence of low-dosage and long-term glucorcorticoid administration.

BACKGROUND: Totally implantable access port (TIAP) provides reliable, long term vascular access with minimal risk of infection and allows patients normal physical activity. With wide use of ports, new complications have been encountered. We analyzed TIAP related complications and evaluated the outcomes of two different percutaneous routes of access to superior vena cava. METHODS: All 172 patients who underwent port insertion with internal jugular approach (Group 1, n = 92) and subclavian approach (Group 2, n = 79) between August 2011 and May 2013 in a single center were analyzed, retrospectively. Medical records were analyzed to compare the outcomes and the occurrence of port related complications between two different percutaneous routes of access to superior vena cava. RESULTS: Median follow-up for TIAP was 278 days (range, 1-1868). Twenty four complications were occurred (14.0%), including pneumothorax (n = 1, 0.6%), migration/malposition (n = 4, 2.3%), pinch-off syndrome (n = 4, 2.3%), malfunction (n = 2, 1.1%), infection (n = 8, 4.7%), and venous thrombosis (n = 5, 2.9%). The overall incidence was 8.7% and 20.3% in each group (p = 0.030). Mechanical complications except infectious and thrombotic complications were more often occurred in group 2 (p = 0.033). The mechanical complication free probability is significantly higher in group 1 (p = 0.040). CONCLUSIONS: We suggest that the jugular access should be chosen in patients who need long term catheterization because of high incidence of mechanical complication, such as pinch-off syndrome.

BACKGROUND: Lipoprotein(a)[Lp(a)] is a subspecies of low-density lipoprotein and has been shown to be associated with pathogenesis of thrombosis-related disease. It is already known that patients with diabetic nephropathy are usually complicated by vascular complications such as coronary artery diseases and cerebrovascular accidents. According to the recent data, Lp(a) level tends to be increased as the proteinuria is increased and renal function are decreased. We evaluated the Lp(a) level to know whether its level is correlated to the severity of diabetic nephropathy. METHODS: We investigated Lp(a) levels in eighty-one patients with Type 2 (non-insulin-dependent) diabetic patients. They were divided into four groups according to the level of urinary albumin excretion and serum creatinine level: Group 1 (n=30): normal renal function + urine microalbumin or=1.5mg/dL. Blood samples were obtained during the morning in the fasting state and separated serum from the it and reserved at -70degrees C. Lp(a) concentration was checked by one-step sandwich ELISA test. All grouped data were expressed as mean+/-SD. ANOVA and unpaired t-test was used to assess the statistical difference between any two means. RESULTS: Lp(a) levels were 30.2+/-4.6mg/dL in Group 1, 42.7+/-8.2mg/dL in group 2, 73.4+/-19.7mg/dL in group 3, and 80.7+/-14.8mg/dL in group 4. The level of Lp(a) in group4, group 3, and group 2 was significantly higher than that of group 1 respectively (P=0.009, 0.001, 0.038). However, no significant correlation was observed between the level of Lp(a) and that of total cholesterol, triglyceride and total lipid in all groups. CONCLUSIONS: these results indicate that Lp(a) concentrations are increased in the patients with diabetic nephropathy with microalbuminuria or overt proteinuria. So, the presence of albuminuria may be the important determinant for the elevated Lp(a) level in diabetic nephropathy.

PURPOSE: To evaluate the treatment results and prognostic factors after radiotherapy in stage IIB uterine cervix cancer. MATERIALS AND METHODS: We retrospectively analyzed the records of 90 patients with stage IIB uterine cervix cancer who received radiotherapy between 9/94 and 12/99. Age was ranged from 28 to 79 years (median 57). Tumor size was > or = 4 cm in 64 patients. Preteatment SCC level was measured in 76 patients. Twenty nine patients received conventional radiotherapy (QD) and the others received modified hyperfractionated radiotherapy (BID). Only 7 patients in BID had tumor size <4 cm. All patients received high dose rate brachytherapy (4 Gy x 7 or 5 Gy x 6). No patient received concurrent chemotherapy during radiotherapy. Follow up period was ranging from 9 to 76 months (median 38). RESULTS: The 5-year overall and disease free survival rates were 73.4% and 71.6%, respectively. Local recurrences occurred in 10% of patients, and distant metastasis in 18.9%. There was a significant correlation between OS/DFS and tumor size (<4 cm; OS 95.2%, DFS 91.4%, > or = 4 cm; OS 63.4%, DFS 63.4%). Pretreatment SCC level was one of prognostic factors only in univariate analysis. CONCLUSION: With modified hyperfractionated radiotherapy, there was very low local recurrence rate (6.6%) and high 5-year overall and disease free survival rate (75.4% and 70.5%), which is comparable to results after concurrent chemoradiotherapy in bulky, locally advanced stage IIB uterine cervix cancer.

A 36-year-old man presented to the hospital with protruding blood vessels in his left lower leg accompanied by cramping. An ultrasonographic examination of the leg revealed focal reflux without truncal vein reflux. During phlebectomy, the varix was found to be connected to the intraosseous vein through a tibial opening. Postoperative computed tomography and magnetic resonance imaging showed an osteolytic lesion in the tibial shaft and an intraosseous vascular anomaly. The patient was discharged without complications and scheduled for periodic follow-ups. This young man’s varicose vein seemed to be from a tibial intraosseous vascular anomaly, which is extremely rare.

We evaluated DNA protection effect of heat shock protein (HSP) against cytotoxic effects of exogenous nitric oxide (NO) and reactive oxygen intermediate (ROI). Cultured human corneal fibroblasts were divided into 4 groups. Control (Group I) was not exposed to a sub-lethal heat treatment. Other 3 groups were exposed to 43 degrees C for 1 hr, then incubated at 37 degrees C during different duration (1, 6, 24 hr, Group II, III, IV, respectively). Expression pattern of HSP 70 was analyzed by Western blot. Cell viability was measured by MTT assay and the relationship between HSP 70 expression and DNA damage was examined by terminal deoxyribonucleotidyl transferase mediated dUTP-digoxigenin nick and labeling (TUNEL) stain and single cell gel electrophoresis. Expression pattern of HSP 70 was dependent on recovery times. Cell viability following heat treatment was significantly increased and the TUNEL positive cell number was decreased at 6 hr. In single cell gel electrophoresis, tail moments were increased in a dose-dependent manner by SNAP and X/XO. Following heat treatment, tail moments showed decreased significantly at 6 hr. These results suggest that induction of HSP 70 by sub-lethal heat treatment is closely related with cytoprotective effects against oxidative stresses in human corneal fibroblasts.
