Aim: Silicone oil is a useful tamponading material used in complex vitroretinal surgery. However, the use of silicone oil is associated with emulsification which can lead to vision threatening complications. The authors developed an experimental model to study the effect of encircling band on silicone oil emulsification. Methods: Two identical artificial eye chambers were constructed with circu...

In their recent paper, Chang and coauthors 1 suggest that silicone lenses should be avoided in phacotrabeculectomy on the basis of their retrospective study of cellular precipitates on intraocular lens (IOL) surfaces. Their finding of statistically increased giant cell precipitates on plate-haptic silicone IOLs (Chiron C10UB) compared with poly(methyl methacrylate) (PMMA) is consistent with the...

Silicone pressure-sensitive adhesives compositions contain a polydimethylsiloxane and a silicone resin, which can enhance the instant bonding ability and bonding strength of the adhesive. In this study, silicone resin was designed to have a low molecular weight and a highly nonpolar chemical structure. The silicone resin was applied to silicone pressure-sensitive adhesives. The molecular struct...

OBJECTIVES The use of silicone implants in cosmetic and reconstructive surgery has been implicated in the development of autoimmune connective tissue diseases. Previous investigation of the influence of short-term silicone implantation using an experimental model of rheumatoid arthritis revealed no adverse influence upon disease despite the generation of autoantibodies against silicone bound pr...

Gallium-67 citrate has long been used for imaging of infection and inflammation. Although gallium-67 uptake due to silicone implants and silicone injections has been previously reported in the literature, very few cases are documented. We report a case of increased gallium-67 uptake in the buttocks in a patient who previously received silicone injections in the buttocks, to reemphasize silicone...

Silicone, which is considered biologically inert, has been used in many different types of medical devices, including tubing; breast, joint and penile implants; artificial heart valves; and intraocular lenses, among others. After a silicone implant is placed, a mild reaction to the foreign body is generally observed, followed by encapsulation (1). Case reports of women with silicone breast impl...

This policy addresses the use of magnetic resonance imaging (MRI) to monitor the integrity of silicone-gel-filled breast implants (hereafter referred to as silicone implants). MRI to monitor for the rupture of silicone implants may be performed without contrast and is more sensitive and specific when a dedicated breast coil is used. Silicone-specific sequences are sometimes used. This policy do...

Very few cases of successful surgical treatment for renal failure due to gluteal silicone injections have been reported in the literature. The silicone toxicity and subsequent renal failure seem to follow repetitive silicone injections and silicone injections in large quantities. This is a case of a 31-year-old woman who developed renal failure after 6 years of gluteal silicone injections who u...

Titanium is a successful biomaterial that possesses good biocompatibility. It is covered by a surface layer of titanium dioxide, and this oxide may play a critical role in inhibiting reactive oxygen species, such as peroxynitrite, produced during the inflammatory response. In the present study, titanium dioxide was coated onto silicone substrates by radio-frequency sputtering. Silicone coating ...
