purpose : to compare the cosmetic and functional results of frontalis sling procedure using silicone rod with polytetrafluoroethylene (ptose-up) in congenital ptosis with poor levator function (lf) methods : in a prospective randomized study, 90 eyes of 66 patients with congenital ptosis that underwent frontalis suspension surgery [31 patients (18 unilateral, 13 bilateral cases) using a silicon...

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...

Deep ultraviolet light-emitting diodes (DUV-LEDs) are considered to be the most promising light sources for effective and fast sterilization under worldwide spread of coronavirus disease (COVID-19). However, it reminds challenging promote extraction DUV-LEDs owing strong DUV absorption conventional encapsulation materials. Herein, solid–liquid hybrid-state gels (SLHGs) fabricate organic lenses ...

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...

Mucosa-adhesive gels can be used as a useful mean of delivering drugs to or via mucosal membranes, and in particular buccal mucosa. Carbomers are among the best mucosa-adhesive materials known. The aim of this study was to compare the results obtained from the mucosa-adhesive strength of aqueous gels containing Carbomers, either alone or in combination, to the data obtained from assessing the d...

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...
