INTRODUCTION AND AIMS Silicone biocompatibility is dictated by cell-surface interaction and its understanding is important in the field of implantation. The role of surface topography and its associated cellular morphology needs investigation to identify qualities that enhance silicone surface biocompatability. This study aims to create well-defined silicone topographies and examine how breast ...

Silicone implants are widely used in aesthetic and reconstructive breast surgery. Silicone lymphadenopathy is a well-known rare complication of implant insertion. Silicone leakage from a rupture or silicone bleeding can accumulate in lymph nodes. Foreign body reactions in the affected lymph nodes may be misdiagnosed as metastasis or malignant lymphadeno pathy upon initial presentation if silico...

PURPOSE The purpose of this study was to determine whether nystagmus has a role in silicone oil emulsification after pars plana vitrectomy and silicone oil injection for complex retinal detachment. METHODS A retrospective review was conducted of the clinical and operative records of eight eyes with nystagmus that underwent pars plana vitrectomy and silicone oil injection for repair of retinal...

AIM To evaluate frequency and risk factors of retinal redetachment after removal of intraocular silicone oil tamponade. METHODS The study included 225 patients who consecutively underwent intraocular silicone oil removal at a mean interval of 10 months after pars plana vitrectomy had been performed by one of two surgeons. Mean follow up time was 17.37 (SD 14.40) months (range 3.02-67.42 month...

      Wetability of biocompatible polymers can be improved by plasma surface modification. The purpose of this study was to surface modify an experimental poly (dimethylsiloxane) rubber (PDMS) material in order to improve its wetability and biocompatibility. Surface properties of the PDMS were characterized using contact angles measurement for wetability analysis. Samples of experimental silico...

To reduce tissue or tumor ingrowth, covered self-expandable metal stents (SEMSs) have been developed. The effectiveness of covered SEMSs may be attenuated by sludge or stone formation or by stent clogging due to the formation of biofilm on the covering membrane. In this study, we tested the hypothesis that a silicone membrane containing silver particles (Ag-P) would prevent sludge and biofilm f...

BACKGROUND Silicone oil, as a major component in conditioner, is beneficial in the moisture preservation and lubrication of hair. However, it is difficult for silicone oil to directly absorb on the hair surface because of its hydrophobicity. Stable nanoemulsions containing silicone oil may present as a potential solution to this problem. METHODS Silicone oil nanoemulsions were prepared using ...

INTRODUCTION The aim of the study is to evaluate interfacial bond strength between silicone prosthetic elastomers and polymethylmethacrylate (PMMA). MATERIALS AND METHODS Silicone elastomers were attached to PMMA and a total 120 specimens were fabricated which were then subdivided into 12 sub-groups. Each sample was then subjected to laboratory test to determine the bond strength. The specime...

Silicone was one of the most common biocompatible materials used for orbital floor reconstruction about twenty to thirty years ago. Recently, surgeons hardly use silicone due to numerous reports of complications such as infection, extrusion and implant displacement. We present a case of chronic infection seen after 28 years of silicone implant used in orbital floor repair. Although it is report...

Robust, transparent elastomeric hydrogels encoded with a bicontinuous structure result from the sequential photopolymerization of the aqueous hydroxyethyl methacrylate phase and crosslinking of the silicone phase of a silicone microemulsion stabilized with an acrylate-functional silicone-poly(ethylene glycol) surfactant.
