BACKGROUND: To compare the diagnostic usefulness of dobutamine stress echocardiography(DSE) and 99mTc-methoxyisobutyl isonitrile SPECT (MIBI SPECT), two studies were performed simultaneously. METHOD: Fifty-six consecutive patients undergoing coronary angiogram and MIBI SPECT for clinical indications without clincal evidence of myocardial infarction were studied prospectively. During the DSE, MIBI was injected at peak stress, and post-stress images of MIBI SPECT were required on hour later. Both echocardiographic and MIBI SPECT images were visually analysed in a blind fashion. RESULTS: On the basis of coronary angiographic findings, the sensitivites of the DSE and MIBI SPECT (n=36) were 89% and 86%, respectively. The specificities of those (n=20) were 90% and 85%, respectively. Among 33 patients without resting perfusion defect on MIBI SPECT, resting regional wall motion abnormalities on DSE were found in only one patient, whereas, resting perfusion defect on MIBI SPECT were found in 9 patients among 41 patients without resting regional wall motion abnormalities on DSE. Among 17 patients who had resting perfusion defects with partial reversibility on MIBI SPECT, resting wall motion abnormalities were present in 11 patients and five of them showed improvement in the regional wall motion during low dose dobutamine infusion. CONCLUSION: Both dobutamine stress echocardiography and MIBI SPECT are useful methods in the detection of the coronary artery disease, however, MIBI SPECT seems to overestimate the regional ischemic myocardium with contractile reserve that can hardly be evaluated with MIBI SPECT.

PURPOSE: Pilomatrixoma is a benign, usually asymptomatic tumor. It presents clinically as a solitary superficial subcutaneous nodule measuring between 0.5 cm and 5 cm in diameter on the head or upper extremeties and has not been reported after skin graft. The objective of this article is to report our experience in treating pilomatrixoma which occurred after split thickness skin graft on the lower extremity. METHODS: A 56-year-old female was treated in August 2005 with a 0.5 X 0.5 cm firm subcutaneous nodule at recipient site of split thickness skin graft on the left medial thigh. The tumor was successfully removed by complete excision and histologic examination was followed. RESULTS: The diagnosis was pilomatrixoma which was characterized by a dual population of proliferating basophilic cells and diagnostic shadow cells. CONCLUSION: The tumor was successfully treated by complete resection. The authors report this very rare case of pilomatrixoma which occurred at recipient site of split thickness skin graft.

PURPOSE: To describe the abnormal gyral and sulcal patterns obtained by means of three-dimensional (3-D) surface-rendering MR imaging in patients with cerebral cortical disease. MATERIALS AND METHODS: Thirteen patients with cerebral cortical disease [M:F=9:4, aged 8 -55 (median, 26.6) years] underwent 3-D surface-rendering MR imaging. Seven had cortical dysplasia and six showed gyral atropic change, conditions which in all cases were pathologically confirmed. All were the subject of conventional brain MRI imaging studies using the MP-RAGE (magnetization-prepared rapid gradient-echo) sequence, and the resulting 3-D data sets were processed on a commercially available workstation. Abnormal gyral and suleal configurations were reviewed. RESULTS: Abnormal gyral and sulcal patterns were seen in all patients. In eight cases these involved the frontal lobe, in three the parietal lobe, and in two the sylvian fissure. In four patients with cortical dysplasia, conventional MR imaging revealed no cortical abnormality, but 3-D surface-rendering MRI indicated that the configuration and orientation of affected gyri and sulci were abnormal. In nine patients in whom an abnormal gyral pattern was revealed by conventional MRI, 3-D surface imaging confirmed the presence of a thick and enlarged gyrus, or that the configuration of affected gyri was atrophic and abnormal. CONCLUSION: In patients with cerebral cortical disease, 3-D surface-rendering MR imaging detects a high rate of abnormal gyral and sulcal patterns.

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.
