PURPOSE: The aims of this study were to find the risk factor and outcomes of patients with an early recurrence (ER) of a hepatocellular carcinoma (HCC) after liver transplantation (LT) and the actual impact of transarterial chemoembolization (TACE) before LT for a HCC on patient survival and HCC recurrence. METHODS: Ninety-eight cases of adult LT, performed between September 1995 and January 2006, were evaluated. The risk factors and prognosis of patient with a HCC after transplantation for an ER, defined as a recurrence within 6 months of transplantation, and the effects of Pre-LT TACE on the disease-free and overall survival rates, as well as the patterns of recurrence after LT, were studied. RESULTS: A total of 18 patients (18.4%) experienced a HCC recurrence after LT; 10 and 8 patients had early and late recurrences, respectively. From a univariate analysis, the serum alpha-fetoprotein (P=0.003), tumor size (P=0.003), serosa invasion (P=0.000), tumor grade (P=0.011) and vascular invasion (P=0.014) were statistically significant risk factors for an ER. From a multivariate analysis, the presence of serosa invasion of a HCC was the only independent risk factor for an ER (P=0.009; OR=9.407: 95% CI, 1.764~50.164). There was no difference in the disease free sur-vival and overall survival rates between the TACE and without TACE groups, but the extrahepatic recurrence rate was higher in the TACE than without TACE group. CONCLUSION: Serosa invasion by a HCC is independently associated with an ER of HCC after LT. Pre-LT TACE does not influence the disease-free and overall survivals after LT for a HCC.

Ovarian myoma is a rare mesenchymal tumor, accounting for only 1% of benign ovarian neoplasm. These tumors only originate from smooth muscle on the walls of blood vessels in the cortical stroma, in the corpus luteum and in the ovarian ligaments at the point of attachment to the ovary. Most patients are asymptomatic and the tumors are usually found incidently during operations or at autopsies. Two cases of ovarian myoma experienced in our hospital recently are reported with a brief review of the literatures."

Multiple endocrine neoplasia (MEN) 2B is charaterized by tumors of endocrine glands, consisting of medullary thyroid carcinoma (MTC), pheochromocytoma and mucosal neuromas of the tongue, lips and other sites. Especially, MTC is the main cause of death in patients who have not received early prophylactic treatment, and MTC in MEN 2B represents more aggressive progress than that of MEN 2A. We encountered two cases of multiple endocrine neoplasia type 2B. One was a 13 month old boy who had familial history of MEN 2B without any symptoms, and the other was a 6-year old boy who manifested multiple mucosal neuromas of the tongue which had been aggravated in four months. Their genetic analysis revealed a point mutation 918th cordon in the RET proto-oncogene. Both of them underwent an operation for prophylactic total thyroidectomy and the 6 year old boy's specimen turned out to be thyroid medullary carcinoma. We encountered two cases of MEN 2B with prophylactic thyroidectomy by early diagnosis of RET proto-oncogene, and report the cases with review of literature.

PURPOSE: With a duration of action of approximately 24 hours and peakless levels, Lantus is a more physiologic basal insulin analogue compared with NPH. The aim of this study was to compare the glycemic control of Lantus plus Humalog with that of premixed insulin in children and adolescents with type 1 diabetes mellitus. METHODS: The subjects consisted of 25 patients with type 1 diabetes mellitus, aged 12-19 years, who changed their insulin regimen from premixed insulin to Lantus plus Humalog. Daily insulin doses, frequency of hypoglycemia, fasting blood glucose, C-peptide concentration and HbA1c before and 6 months after Lantus treatment were compared. 24 hour blood glucose of 11 patients among Lantus treatment group (n=25) and premixed insulin treatment group (n=10) were self-monitored and compared. RESULTS: 6 months after Lantus treatment, the episodes of hypoglycemia were reduced by 50%(15.1 vs. 7.6 events/month), especially nocturnal hypoglycemia by 67%(6.7 vs. 2.5 events/month). HbA1c was reduced from 9.3% to 8.7% after Lantus treatment. Self-monitored blood glucose of Lantus treatment group at postbreakfast 30, 60, 90 and 120 minutes were 171.1, 169.5, 171.0 and 154.1 mg/dL respectively and lower than those of premixed insulin treatment group (259.7, 282.7, 280.0 and 250.9 mg/dL respectively). CONCLUSION: Compared with premixed insulin, Lantus plus Humalog is more effective in glycemic control and reduction in nocturnal hypoglycemia in children and adolescents with type 1 diabetes mellitus.

BACKGROUND: Diffusion-weighted MR imaging (DWI) was designed to detect the random molecular otion of water in tissue. DWI has gained increasing interest recently because it can demonstrate yperacute stroke earlier than any other imaging methods so far. The purpose of our study was to etermine the clinical usefulness and significance of DWI compared with those of Fast Spin Echo T2-weighted image (SE T2WI) and Fluid Attenuated Inversion Recovery (FLAIR) image in acute and subacute ischemic stroke. METHOD: Twenty-five adult patients with clinical diagnoses of acute or subacute cerebral infarctions were imaged with fast SE T2WI, FLAIR and DWI using a 1.5-T image. RESULTS:All the patients had areas of high signal intensity indicating acute or subacute lesions on DWI and these lesions provide an excellent clinicoanatomic correlation. CONCLUSIONS: DWI is most useful in the diagnosis and localization of acute or subacute lacuna or subcortical infarction in patients with preexisting chronic infarctions or white matter hyperintensity showing high signal intensity similar to acute or subacute infarctions on T2WI or FLAIR image.

Lymphocytic infundibuloneurohypphysitis(LINH) is a newly classified disorder and proposed as a common cause of idiopathic central diabetes insipidus. It is characterized by thickening of the infundibulum and/or pituitary stalk and absence of high signal in the neurohypophysis in sellar MRI and the microscopic findings of diffuse lymphocytic infiltration within the neurohypophysis. A 12year-old boy presented polyuria and headache. The result of water deprivation test was compatible with central diabetes insipidus. Brain MRI showed thickening of the pituitary stalk and loss of high signal in the neurohypophysis. Craniotomy and excisional bi6opsy was done under the impression of pituitary tumor. Microscopically, neurohypophysis showed dense lymphocytic infiltration and no malignant cells. Six months after the operation, the previously thickened pituitary stalk and neurohypophysis appeared normal in follow-up MRI.

PURPOSE: Although microalbuminuria is considered as an early marker of nephropathy in diabetic adults, available information in diabetic adolescents is limited. The aim of this study was to investigate prevalence and frequency of regression of microalbuminuria in type 1 (T1DM) and type 2 diabetes mellitus (T2DM) patients with childhood onset. METHODS: One hundred and nine adolescents (median, 18.9 years; interquartile range (IQR), 16.5-21.0 years) with T1DM and 18 T2DM adolescents (median, 17.9 years; IQR, 16.8-18.4 years) with repeated measurements of microalbuminuria (first morning urine microalbumin/creatinine ratios) were included. The median duration of diabetes was 10.1 (7.8-14.0) years and 5.0 (3.5-5.6) years, respectively, and follow-up period ranged 0.5-7.0 years. Growth parameters, estimated glomerular filtration rate, glycosylated hemoglobin (HbA1c) and lipid profiles were obtained after reviewing medical record in each subject. RESULTS: The prevalence of microalbuminuria at baseline and evaluation were 21.1% and 17.4% in T1DM, and 44.4% and 38.9% in T2DM. Regression of microalbuminuria was observed in 13 T1DM patients (56.5%) and 3 T2DM patients (37.5%), and progression rate was 10.5% and 20% in T1DM and T2DM respectively. In regression T1DM group, HbA1c at baseline and follow-up was lower, and C-peptide at baseline was higher compared to persistent or progression groups. In T2DM, higher triglyceride was observed in persistent group. CONCLUSION: Considerable regression of microalbuminuria more than progression in diabetes adolescents indicates elevated urinary microalbumin excretion in a single test does not imply irreversible diabetic nephropathy. Careful monitoring and adequate intervention should be emphasized in adolescents with microalbuminuria to prevent rapid progression toward diabetic nephropathy.

PURPOSE: Subacute sclerosing panencephalitis(SSPE) is a severe and usually fatal neurodegenerative disorder of childhood and adolescence. The etiology is related to previous measles infection especially during the first 2 years of life. Since recent measles epidemics in Korea may increase the late risk of SSPE, the authors investigated the clinical characteristics of SSPE focusing on brain MRI. METHODS: Six cases(4 males, 2 females) of SSPE patients were retrospectively reviewed for clinical, EEG, laboratory and brain MRI findings. RESULTS: Four of 6 had a history of measles infection in the first year of life. Clinical manifestations were as follows:myoclonus(6), falling(4), ataxia(4), dysarthria(3), seizures (2), involuntary movements(2), tremor(2), head drop(1), sleep disturbance(1). In all cases, CSF IgG, CSF IgG/albumin ratio, and CSF/serum IgG index increased, oligoclonal bands were positive, and CSF antimeasles antibodies were positive. Frontal high amplitude sigma activities and anteriorly-accentuated multifocal epileptiform discharges were noted on EEG. Brain MRI revealed T2-weighted high signal intensity of the deep white matter. CONCLUSION: The diagnosis of SSPE depends on characteristic clinical features and elevation of measles antibodies in CSF, supported by others including EEG, CSF and brain MRI findings. We hope the clinical characteristics we mentioned may be useful for the early diagnosis and active management of SSPE in Korea.
