چکیده
Aetna considers endoscopic injection of dextranomer/hyaluronic acid copolymer (Deflux), polydimethylsiloxane (Macroplastique), polytetrafluoroethylene (Teflon), or other bulking agents approved by the U.S. Food and Drug Administration (FDA) for vesicoureteral reflux (VUR) medically necessary for the treatment of members with primary or secondary VUR who have any of the following conditions when conservative treatments (e.g., prophylactic antibiotics and clean intermittent catheterization) have failed:

Secondary cytotoxicity of cross-linked dermal sheep collagens during repeated exposure to human fibroblasts.
We investigated commercially available dermal sheep collagen either cross-linked with hexamethylenediisocyanate, or cross-linked with glutaraldehyde. In previous in vitro studies we could discriminate primary, i.e. extractable, and secondary cytotoxicity, due to cell-biomaterial interactions, i.e. enzymatic actions. To develop dermal sheep collagen for clinical applications, we focused in this ...
متن کاملDifferentiation of mesenchymal stem cells into osteoblasts on honeycomb collagen scaffolds.
Tissue engineering using living cells is emerging as an alternative to tissue or organ transplantation. The adult mesenchymal stem cells can be differentiated into multilineage cells, such as adipocytes, chondrocytes, or osteoblasts when cultured with specific growth factors. In the present investigation, we have studied the effect of honeycomb collagen scaffolds for the adhesion, differentiati...
متن کاملComparison of smooth-gel hyaluronic acid dermal fillers with cross-linked bovine collagen: a multicenter, double-masked, randomized, within-subject study.
BACKGROUND A new family of next-generation non-animal hyaluronic acid (HA) dermal fillers was approved by the FDA in June 2006. Compared with other HA fillers available in the United States at the time of writing, these new fillers have a higher concentration of HA, higher concentration of cross-linked HA, and a smooth consistency--which should promote long-lasting corrections and a smooth, nat...
متن کاملAutologous collagen dispersion (Autologen) as a dermal filler: clinical observations and histologic findings.
OBJECTIVE To assess the histologic behavior and clinical efficacy of autologous collagen dispersion (Autologen) in augmenting human dermis. SUBJECTS Adult patients of the Facial Plastic Surgery Clinic at The New York Eye and Ear Infirmary who were undergoing facial aesthetic surgery with skin excision. METHODS Five patients were injected intradermally with Autologen in one postauricular are...
متن کاملNano-hydroxyapatite/collagen film as a favorable substrate to maintain the phenotype and promote the growth of chondrocytes cultured in vitro
Autologous chondrocyte implantation (ACI) has emerged as a novel approach to cartilage repair through the use of harvested chondrocytes. However, the expansion of the chondrocytes from the donor tissue in vitro is restricted by the limited cell numbers and the dedifferentiation of the chondrocytes. The present study investigated the effect of collagen-based films, including collagen, hydroxyapa...
