PURPOSE: The purpose of this study is to evaluate findings in MRI which maybe useful in differential diagnosis of cervical lymph node enlargement. MATERIALS AND METHODS: We retrospectively analyzed the MRI findings of cervical lymph node enlargement in surgically proven 13 patients. We analyzed the location, size and shape, signal intensity, margin between node and surrounding structures degree and patterns of contrast enhancement RESULTS: No disease specificity in location and size of lymphadenopathy. was demonstrated in MRI. Most lymph nodes shows isointensity or slightly increased signal intensity to adjacent muscle on T1WI and high signal intensity on T2WI. Most of the cases showed contrast enhancement with metastatic lymph nodes showing ring-like and/or patchy enhancement. Tuberculous lymphadenopathy showed homogeneous or rather thick walled ring-like enhancement and one or multiple central nonenhancing portions of eccentrical location in the node. Relatively homogeneous enhancements were noted on reactive lymphold hyperplasia, Lymphoma and Castleman's disease. CONCLUSION: MR imaging was helpful in differentiation of cervical lymph node enlargements. Tuberculous lymphadenopathy showed characteristic findings of rather spherical shaped, thick walled ring enhancement and multiple eccentrically located central nonenhancing portions.

The occurrence of double primary cancer of the esopbagus and duodenum is considered very rare. Moreover, it is difficult to manage this type of double cancer because esophageal cancer has a biologic tendency to early metastasis. We report a case of double primary cancer, which we have synchronously confirmed esophageal squamous cell carcinoma and duodenal adenocarcinoma with gastrofiberscopic biopsy, and then treated them by gastrojejunostomy and systemic chemotherapy.

OBJECTIVE: Current guidelines for initiating dialysis therapy are based on level of kidney function and clinical evidence of uremia. In several studies, early dialysis showed no benefit in mortality and complication rate. Thus we examined whether the timing of initiation of dialysis influenced mortality and complication rate with renal failure. METHODS: We retrospectively studied the clinical outcomes in 290 patients with renal failure who underwent dialysis therapy from 2001 to 2009. The early and late dialysis group defined as values more than and less than 10 mL/min/1.73 m2. The primary outcome was death from any cause and the secondary outcome was complication event. RESULTS: The survival rates and complication events were compared based on the estimated glomerular filtration rate, the survival rate in late dialysis group is better than in early dialysis group and the significant prognostic factors determined by multivariate analysis were age and residual renal function at time of initiation of dialysis. No difference in complication events were observed. Subgroup analysis in hemodialysis group shows no significant difference in survival rate. CONCLUSION: The survival rate in late dialysis group is better than in early dialysis group. And the complication rate were not different in two groups.
