PURPOSE We evaluated the medium term efficiency of silicone micro-implants injected in women with intrinsic sphincter deficiency. MATERIALS AND METHODS A total of 21 women with intrinsic sphincter deficiency underwent transurethral injection of silicone micro-implants between August 1996 and February 1997. Each patient was assessed preoperatively by questionnaire, physical examination and uro...

OBJECTIVE To compare long-term complications of silicone sponge, silicone rubber, and MIRAgel used as episcleral buckling elements. METHODS Medical reports were reviewed of 805 patients with cryotherapy and episcleral buckle for rhegmatogenous retinal detachment who were operated on by 1 of us (M.R.-P.) between March 1984 and December 1997. Average follow-up was 76 months. Symptoms and signs ...

STATEMENT OF PROBLEM The success of most non-implant-retained extraoral prostheses depends on retention derived from skin adhesives. Part 1 of this study found that Skin-Prep Protective Dressing improved the retentive properties of adhesives and that Secure(2) Medical Adhesive was stronger than Epithane-3. Part 2 investigates the application of a second layer of adhesive to the prosthesis, whic...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016217023 DESCRIPTION A 77-year-old woman underwent pars plana vitrectomy for recurrent retinal detachment with silicone oil injection 10 years before presentation. Also the patient was placed on antiglaucoma medications. The patient had a history of recurrent corneal ulcerations in both eyes du...

The use of an organic solvent can allow to increase the mass transfer, and thereby biodegradation, of hydrophobic gaseous pollutants. The biodegradation of hexane by a Pseudomonas aeruginosa strain was thus optimized in a two phase partitioning bioreactor (TPPB). Silicone oil was first selected among various organic solvents based on its biocompatibility and resistance to P. aeruginosa and its ...

OBJECTIVE To compare anatomic and visual acuity outcomes, as well as complication rates, after retinal detachment repair using 1000- vs 5000-centistoke silicone oil. METHODS Records of all patients who underwent retinal detachment repair with silicone oil at one institution between January 1, 1995, and December 31, 2000, were reviewed. Anatomic outcomes included retinal redetachment and macul...

Purpose. To report a new approach for removal of silicone oil. Methods. All surgeries were performed using 23-gauge vitrectomy system with two transconjunctival sutureless cannulas. At the beginning, most of the silicone oil was removed by traditional microinvasive vitrectomy system through inferior-temporal cannula. Then, the blood transfusion tube is removed from the inferior-temporal cannula...

PURPOSE To pre p a re and explore new solutions of semifluorinated alkane in silicone oil, which have a specific gravity slightly higher than silicone oil and vitreous fluid (referred to in the following as heavier-than-water silicone oils (HWSs), and to investigate, in vitro, whether HWSs can be used to plug retina holes, while allowing dehydration of the subretinal space. METHODS HWS soluti...
