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 ...

HEAVY silicone oils have shown promising results in the treatment of retinal detachments in the inferior quadrant in several studies. However, their use remains controversial, attendees at a symposium at the 7th EURETINA Congress heard. Proponents of silicone oil say that the specific gravity of these compounds makes them more efficient than conventional silicone oils in providing inferior tamp...

Phase Change Materials In article 2206301, Chatterjee, Chaudhari, and Anand outline the selection criteria to identify phase change materials that can thermally respond by harnessing condensational latent heat simultaneously delay frost formation shed ice from surfaces for devising protective coatings capable of freeze-protection in wintry environments.

Silicone breast prostheses have been widely used for several decades. Until recently, about 150 000 women received these implants annually in the United States—80% for breast augmentation and the others almost exclusively for reconstruction after cancer surgery. There is little doubt about the beneficial psychological eVects of breast implants, but there is increasing awareness of alleged adver...

A quat-silicone micro-emulsion (particle size <40 nm), an amino-silicone macro-emulsion (110 nm), and an alkyl modified silicone macro-emulsion (740 nm) were used to modify Scots pine (Pinus sylvestris L.) sapwood. Treated and uncoated boards were exposed to natural weathering for one year along with water treated controls according to EN 927-3. The treatment with silicone emulsions did not enh...

Reworking electronic packages is an integral process related to diagnostics and salvaging valuable materials. It is a meticulous and time-consuming procedure that requires some knowledge of the package material composition to determine compatible cleaning solutions and processes. Silicone adhesives are being used more frequently due to their ability to minimize shear stress during temperature c...

PURPOSE To present the finding of tiny silicone oil droplets in 15 eyes of 15 patients after intravitreal injections of an anti-vascular endothelial growth factor agent or triamcinolone acetonide and to discuss the likely source of silicone oil. METHODS In an observational case series, charts of patients who had undergone intravitreal injections by one surgeon were reviewed retrospectively. T...
