This paper reports a case of patient suffering from a solitary fibrous tumor in the retroperitoneum (SFTR) with hypoglycemia who was cured by surgery. Immunohistochemistry results show that the tumor cells positively expressed CD34, Bcl-2, CD99, Vimentin, and insulin, but were negative for EMA, HMB45, S100, and SMA. The excessive expression of insulin-like growth factor may be an important cause of hypoglycemia in SFTR patients. The diffuse expression of CD34 in the tumor is a highly specific marker of SFT. Complete resection may be the best treatment for such type of patients. © 2015 Baishideng Publishing Group Inc. All rights reserved. Source

BACKGROUND: There are many types of porcelain-fused-metal (PFM) repair materials, each material has its own properties and toxic effects on periodontal tissue cells. OBJECTIVE: To explore the effect of Au-Pt based PFM crown on the periodontal tissue of restored teeth. METHODS: Twenty-six maxillary incisors that possessed Au-Pt based PFM crowns in 21 patients were involved in the study. The contralateral homonymy nature teeth were treated as control teeth. The patients were followed up 6 to 8 months after the placement of the crowns. RESULTS AND CONCLUSION: All of the restorations were clinically accepted, either in marginal depth or in marginal discrepancies. There were no significant differences of plaque index and the concentration of vascular endothelial growth factor and tumor necrosis factor-α between the test and the control teeth after the placement of Au-Pt based PFM crown (P > 0.05). However, the probing depth, sulcus bleeding index and gingival cervicular fluid volume of the test teeth were significantly higher than those of the control teeth (P < 0.05). Au-Pt based PFM crown has negative influences on gingival health of the restored teeth. Source
