BACKGROUND: The survival rate of children with neuroblastoma has been improved over 20 years, excluding the metastatic disease, in which it does not exceed 20% so far. New treatment modalities have been developed to improve the outcome in metastatic disease. Preoperative chemotherapy reduce the size, the vascularity and the adhesiveness, so increase the resectability of the primary tumor. This retrospective clinical study was designed to review the survival rate in neuroblastoma and to analyze the effect of preoperative chemotherapy in the view point of neoadjuvant therapy on long-term survival in advanced disease. METHODS: One hundred and thirty-four cases were reviewed from 135 patients with neuroblastoma registered at the Department of Pediatrics in Seoul National University Children's Hospital from January, 1985 till December, 1995. The survival rate was reviewed according to the stage. The age, sex of the patients, the stage, anatomical site of the tumor, the level of serum ferritin and neuron-specific enolase were analyzed for the risk factors on survival. RESULTS: Ranges of age at diagnosis were from 1 month to 166 months with the median of 39 months. Five year survival rates and five year disease-free survival rates were 100%, 100% in stage 1(n=5), 90.9%, 90.9% in stage 2(n=13), 43.4%, 40.6% in stage 3(n=19), 27.1%, 19.8% in stage 4(n=95) and 100%, 100% in stage 4S(n=2), respectively. In stage 3, five year survival rate was 52.5% in group receiving neoadjuvant chemotherapy, 28.6% in control group(P=0.02). Five year disease-free survival rate was also noted as 48.6%, 28.6% in each group(P=0.02). In stage 4, five year and ten year survival rates were 27.6%, 23.6% in group receiving neoadjuvant chemotherapy, 26.9%, 0% in control group(P=0.02). Five year and ten year disease-free survival rates were 14.3%, 14.3% in group receiving neoadjuvant chemotherapy, 20%, 0% in control group (P=0.11). In univariate analysis, the age, the stage, and the site of primary tumor appeared to affect the long-term survival. CONCLUSION: Neoadjuvant chemotherapy and delayed primary surgery contribute for advance in survival in advanced neuroblastoma via increasing the resectability of the primary tumor.

We report a case of recurrent choroidal neovascularization (CNV) in an eye with chorioretinal coloboma. A 36-year-old woman presented complaining of decreased visual acuity (VA) in her left eye. Best corrected visual acuity (BCVA) was 20/200 and iris coloboma was observed. Funduscopy and fluorescein angiography (FA) showed CNV in the superior extrafoveal region with chorioretinal coloboma reaching just inferior to the optic disc. No other cause for CNV was observed except for the chorioretinal coloboma. BCVA improved to 20/30 after laser photocoagulation. She revisited our clinic for deteriorating VA (20/400) in the same eye 3 years after treatment. Funduscopy and FA demonstrated recurrent CNV with subfoveal hemorrhage. Photodynamic therapy (PDT) was followed by three consecutive intravitreal bevacizumab injections (IVB) for the subfoveally-located CNV. However, the CNV persisted with the appearance of a fresh subretinal hemorrhage. Additional PDT was combined with IVB on the same day 6 months after the initial PDT. The CNV regressed 3 months after treatment and has not recurred as of 8 months after the last treatment. The patient's BCVA improved to 20/60. This case suggests that PDT combined with IVB can be an alternative treatment for the management of recurrent CNV after laser photocoagulation in eyes with chorioretinal coloboma.

PURPOSE: To examine long-term natural history and visual prognosis of idiopathic subfoveal or juxtafoveal choroidal neovascularization (CNV). METHODS: A retrospective review of fourteen eyes diagnosed as idiopathic CNV at Seoul National University Hospital was done. Patients under 40 years old whose follow-up period of more than 36 months without treatments were included. Best corrected visual acuity (BCVA) with biomicroscopic and fluorescein angiographic examinations was measured at the initial and final visit. Clinical factors correlated with final visual acuity were analyzed. RESULTS: Mean age was 34 years ranged from 20 to 40 years and male to female ratio was 4 to 10. Patients were followed for a median of 45 months (range, 36-60 months). On initial examinations, BCVA in 14 eyes was over 0.15 with eight eyes under 0.5 and with six eyes over 0.6. Subfoveal CNV were in 12 eyes and juxtafoveal were in 2. All had the size smaller than 1DD (disc diameter). On the final visit, BCVA in 14 eyes was over 0.2 with three eyes under 0.5 and 11 eyes more than 0.6. Five eyes (36%) retained visual acuity and 8 eyes (57%) improved more than two lines. BCVA in one eye deteriorated two lines. In 6 eyes (42%), CNV was found to be regressed after the follow-up period. Initial visual acuity was significantly correlated with final visual acuity (p=0.013, Pearson correlation test). CONCLUSIONS: Idiopathic CNV has favorable visual prognosis and a tendency of spontaneous involution.

Left-sided heart failure can be complicated in the patient suffering with thyrotoxicosis; however, predominantly right heart failure in thyrotoxic patients is a rare condition. We present here a case of reversible right-heart failure with severe tricuspid regurgitation associated with thyrotoxicosis. A 71-year-old woman was admitted to the hospital because of a 10-day history of shortness of breath and indigestion. On echocardiography, there was a normal-sized left ventricle with preserved systolic and diastolic function. However, the right atrium and ventricle were dilated, and there was incomplete systolic coaptation of the tricuspid leaflets, resulted in severe tricuspid regurgitation. The maximal velocity of tricuspid regurgitation was 3.7 m/sec and the estimated pressure gradient between the right two chambers was 55 mmHg. After treatment that included diuretics and antithyroid drug (methimazole), the symptoms of right heart failure resolved. Four weeks later, a second echocardiogram was obtained revealing a normalized right atrium and ventricle, trivial tricuspid regurgitation and the resting pulmonary hypertension had disappeared.

PURPOSE: To determine the phenotypic characteristics of peripheral CD8(bright) T cells. METHODS: Forty patients with Behcet's disease (BD) with uveitis (active: 20; inactive: 20) and 20 healthy controls were recruited in this study. Phenotypic analysis of fresh PBMCs was performed using anti-CD8 mAb and anti-CD56 mAb in conjunction with a three- or four-color immunofluorescence tests for the expression levels of the following molecules: CD11b, CD27, CD45RA, CD45RO, CD62L, CD94, NKG2D, and HLA-DR. RESULTS: CD27 and CD62L were down-regulated on peripheral CD8(bright) T cells in patients with active Behcet's uveitis in contrast to the up-regulation of CD11b and HLA-DR. These phenotypic natures were remarkable in the CD56+ subsets. CD45RA(dim)CD45RO- phenotypes were expanded in peripheral CD8(bright)CD56+ T cells according to the disease activity. Interestingly, in active Behcet's uveitis, CD94 was up-regulated on peripheral CD8(bright)CD56+ T cells in BD in contrast to the down-regulation of NKG2D compared with the normal controls. CONCLUSIONS: CD8(bright)CD56+ T cells are characterized by activated effector phenotypes with functional NK receptors and they may play immunopathogenic roles in Behcet's uveitis.

A case of giant ureteral polyp is presented. The patient was 76- year-old female complaining of left flank discomfort and irritative voiding symptoms. Radiologic examination revealed filling defects of left lower ureter. Cystoscopic finding showed a tubular mass, to-and-pro movement through left ureteral orifice. Excision of ureteral polyp and left ureteroureterostomy were performed. Pathologic findings showed fibroepithelial polyp and it's narrow pedicle was 10cm in length and 5-8mm in diameter.
