Ehlers-Danlos Syndrome(EDS) is an inherited disorder of the connective tissue disease that is usually transmitted as autosomal dominant trait. The defect in the biogenesis of collagen results in varying degree of skin hyperextensibility, joint hypermobility, skin fragility and bruising. There have been several reports of cardiac or great vessel abnormalities in patients with the EDS. A 45-year-old Woman was admitted to Maryknoll hospital because of orthopnea, palpitation and epigastric discomfort. Physical examination reveals multiple variable sized bruises and increased hyperelasticity on skin, and hypermobile joint in knee and proximal interphalanges of both hands. Mitral valvular prolapse and atrial septal defect were detected by echocardiography. We report a case of EDS accompanied by mitral valvular prolapse and ostium secundum atral septal defect with brief review of literature.

BACKGROUND/AIMS: Although gastric hyperplastic polyps are usually considered as benign lesions, a low risk of carcinomatous conversion is currently recognized. We aimed to identify the characteristics of hyperplastic polyps undergoing neoplastic transformation. METHODS: A total of 269 gastric hyperplastic polyps from 216 patients removed by endoscopic polypectomy (EP) or surgical resection were enrolled in this study, and their endoscopic pictures and pathology slides were reviewed. RESULTS: Neoplastic transformation was detected on forceps biopsy specimen in 11 cases. However, the pathology findings from the EP or surgical specimen revealed neoplastic transformation in 14 cases (5.2%; 4 with dysplasia and 10 with adenocarcinoma). No significant difference was found between hyperplastic polyps with and without neoplastic transformation in age, sex, location, number of polyps or gross appearance. However, neoplastic transformations were more frequently found in gastric hyperplastic polyps >1 cm than in polyps < or =1 cm (12 of 143; 8.4% vs. 2 of 126; 1.6%) (p=0.013). CONCLUSIONS: Neoplastic transformations were more frequently found in gastric hyperplastic polyps >1 cm. Therefore, EP should be considered for gastric hyperplastic polyps >1 cm for the accurate diagnosis and definitive treatment.

Gliosarcoma (GS) is a rare variant (2%) of glioblastoma (GBM) that poses clinical genomic challenges because of its poor prognosis and limited genomic information. To gain a comprehensive view of the genomic alterations in GS and to understand the molecular etiology of GS, we applied whole-exome sequencing analyses for 28 GS cases (6 blood-matched fresh-frozen tissues for the discovery set, 22 formalin-fixed paraffin-embedded tissues for the validation set) and copy-number variation microarrays for 5 blood-matched fresh-frozen tissues. TP53 mutations were more prevalent in the GS cases (20/28, 70%) compared to the GBM cases (29/90, 32%), and the GS patients with TP53 mutations showed a significantly shorter survival (multivariate Cox analysis, hazard ratio=23.9, 95% confidence interval, 2.87–199.63, P=0.003). A pathway analysis showed recurrent alterations in MAPK signaling (EGFR, RASGRF2 and TP53), phosphatidylinositol/calcium signaling (CACNA1s, PLCs and ITPRs) and focal adhesion/tight junction (PTEN and PAK3) pathways. Genomic profiling of the matched recurrent GS cases detected the occurrence of TP53 mutations in two recurrent GS cases, which suggests that TP53 mutations play a role in treatment resistance. Functionally, we found that TP53 mutations are associated with the epithelial–mesenchymal transition (EMT) process of sarcomatous components of GS. We provide the first comprehensive genome-wide genetic alternation profiling of GS, which suggests novel prognostic subgroups in GS patients based on their TP53 mutation status and provides new insight in the pathogenesis and targeted treatment of GS.

PURPOSE: Childhood acute immune thrombocytopenic purpura (ITP) is a benign hematologic disease. Therapy does not affect the natural history of the illness. We evaluated the clinical and laboratory findings, treatment and prognosis of childhood acute ITP in Korea through a retrospective multicenter study. METHODS: We analyzed retrospectively the data of 1, 829 children with acute ITP through survey of 33 hospitals among 43 hospitals in Korea from Sep. 1992 to Aug. 2001. RESULTS: Male to female ratio was 1.3: 1 and the median age at the diagnosis of ITP was 2.9 (0.1 17) years. Median duration of follow up was 6 months. One hundred and forty nine cases of the total 1, 829 patients (8.1%) received no treatment. The initial median platelet count of the non-treated group was 42, 500/mm3. Among the 861 cases who were followed up over 6 months, 315 cases (36.6%) progressed into chronic ITP. Associated with this high rate of chronicity of childhood acute ITP patients in Korea, we must consider the fact that acute ITP patients with fast improvement in the first episode tend not to follow up. Considering that fact, the rate of chronicity becomes 17.2% of the 1, 829 acute ITP patients. The treated group used many kinds of treatment methods. Intravenous immunoglobulins (IVIG) with or without prednisolone (PD) (67.5%) were the most commonly used regimens. In the group treated with IVIG alone, the platelet count began to rise above 50, 000/mm3 at 2.6 days, 100, 000/mm3 at 3.7 days and 150, 000/mm3 at 4.9 days. Four hundred and twenty two cases of the 1, 686 (25.0%) cases followed up after first episode of ITP relapsed. The relapse rate was significantly higher in older patients and in girls than in younger patients and in boys (P< 0.05). The chronicity of ITP statistically increased with age (P< 0.05) and that was the only valuable factor. CONCLUSION: Despite the fact that childhood acute ITP is a pretty common disaese, there is no agreement on the best treatment method for this disease. The establishment of Korean treatment guideline of childhood acute ITP, based on an analysis of multicenters, seems to be needed.
