Silicone granulomas following free silicone gluteal augmentation

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 emulsions.

Silicone polymers are a class of hybrid organic/inorganic polymers, that show desirable surface properties such as low surface energy and high flexibility, which enables even a very high molecular weight chain to achieve optimal orientation at the interface. They have excellent physical properties such as water repellency, heat stability, and high resistance to chemical and UV attack. Silicone ...

Silicone IOL biocompatibility--not all silicone is the same.

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...

Laser resurfacing of silicone-injected skin: the "silicone flash" revisited.

OBJECTIVE To determine whether prior silicone injection increases the risks associated with carbon dioxide laser resurfacing. DESIGN Laboratory determination of the effect of laser energy on liquid silicone; histologic evaluation of silicone-injected skin after lasing; and histologic demonstration of silicone deposits in all layers of dermis years after injection of silicone as filler fluid. ...
