To evaluate the correlation between the internal echo patterns and henodynamics in hepatic cavernous hemangioma, we compared the interanal echo pattern with the hemodynamic pattern examined by intravenous bolus CT(multi-phase incremental bolus dynamic CT) in 34 diagnosed hemangiomas (25 patients). We classified cavernous hemangiomas as two different hemodynamic patterns according to the findings of the early phase of intravenous bolus CT scans. Early enhancing type means that most portion of a mass is enhanced during the early hpase and late enhancing type means that only minimal peripheral portion of a mass is enhanced during the early phase. We classified ultrasonogrphic patterns as hypoechoic and hyperechoic according to main echogenicity of the mass. The late enhancing type tends toward the high echo type (20/21) and the early enhancing type tends to ward the low echo type (11/13) (p<0.01) Therefore, we believe that the early enhancing type which represents rapid contrast inflow toward mass, contains large portions of cavernous space and showes hypoechoic, but late enhancing type which represents late contrast inflow toward a mass, contains large portions of fibrous space and showes hyperechoic. In conclusion, there was significant correlation between internal hemodynamics and echo patterns in hepatic cavernous hemangioma.

Wiskott-Aldrich Syndrome is an X-linked disorder characterized by recurrent infection, thrombocypenia and eczema. Various defects in cell-mediated immunity and deficient antibody reponse to carbohydrate antigens have been described. We experienced a case of Wiskott-Aldrich Syndrome of 28 months old male patient. He has been suffered from multiple petechiae with bleeding, recurrent pyogenic infections and generalized eczema since 3 months of age. Immunological abnormalities are as follows: 1) Serum IgM was gradually decreased, while IgA and IgE were increased. 2) Antibody response against polysaccharide antigen (PRP) was not observed after 3 times of PRPT immunization. 3) CD4/CD8 ratio was reversed (0.6). 4) Proliferative response of mononuclear cells was significantly reduced, and CMI skin test also showed negative results. A brief review of literature was made.

PURPOSE: H. pylori infection was recently reported to be associated with unexplained iron-deficiency anemia(IDA) in children and adolescents. H. pylori-related IDA was thought to occur due to GI blood loss, scavenging of iron by H. pylori and iron malabsorption. The aim of this study was to examine how the status of H. pylori infection and age of children affected RBC indices, serum iron level and TIBC. METHODS: We performed esophagogastroduodenoscopy, and examined RBC indices, serum iron and TIBC on 178 pediatric patients with recurrent abdominal pain. H. pylori infection was assessed by CLO test and silver stain of gastric biopsy specimen. RESULTS: H. pylori infection was found in 42 of 178 patients(23.6%). In children with H. pylori infection, the prevalence of iron deficiency(ID) and IDA(39.0% and 10.3%, respectively) was higher than in children without H. pylori infection(29.6% and 4.1%, respectively), but there was no statistically significant difference. Serum iron level was lower(69.5+/-32.7 vs 77.3+/-34.1g/dL; P= 0.08) and TIBC was higher(380.8+/-50.4 vs 366.9+/-47.0g/dL; P=0.09) in children with H. pylori infection than in children without H. pylori infection. All RBC indices and iron saturation were lower in children with H. pylori infection than in children without H. pylori infection, but there was no significant difference between the two groups. In correlation analysis, serum iron, Hgb, Hct, MCV and MCH were significantly increased by age in children without H. pylori infection (P<0.05), but MCH and MCHC were decreased significantly(P<0.05) by age in children with H. pylori infection. In multiple regression analysis, the change of serum iron, MCH and MCHC by age was significantly influenced by the status of H. pylori infection(P<0.05). CONCLUSION: H. pylori infection decreases RBC indices and serum iron and increases TIBC in children. These changes become prominent as age increases. This age effect rnay be related to the duration of H. pylori infection. (J Korean Pediatr Soc 2000;43:755-762)

The cutaneous metastaaes from carcinoma of breast produce four definite clinical types: inflammatory carcinoma, telangiectatic carcinoma, nodular carcinoma, and carcinoma en cuirasse. We present a case of 51-year-old woman who had purpuric, hard, sclerotic plaque with ulceration, crust and. several pea-sized hemorrhagic papulovesicular eruptions on the right chest wall for one year. Histopathological findings show metastatic ductal carcinoma but, the primary focus was not determined.

Congenital agenesis of the right lobe of liver is a rare anomaly and only 33 cases have been reported. CT showed absence of the right lobe of liver and compensatory hypertrophy of the other lobe. We report the CT findings of a new case of this anomaly with a review of the literatures.
