Purpose. The aim of this study was to evaluate three novel surface treatments intended to improve osseointegration of zirconia implants: selective infiltration etching treatment (SIE), fusion sputtering (FS), and low pressure particle abrasion (LPPA). The effects of surface treatments on roughness, topography, hardness, and porosity of implants were also assessed. Materials and Methods. 45 zirc...

Fungal endophthalmitis is rare but may complicate glaucoma drainage device surgery. Management is challenging as the symptoms and signs may be subtle at initial presentation and the visual prognosis is usually poor due to its resistant nature to treatment. At present there is lesser experience with intravitreal injection of voriconazole as compared to Amphotericin B. We present a case of succes...

Neovascular glaucoma is commonly treated surgically with implantation of glaucoma drainage devices. We report the case of a 57-year-old man who underwent an uneventful Ahmed glaucoma valve (AGV) placement for radiation-induced neovascular glaucoma but later developed early postoperative infection with tube exposure. The infection was identified 3 weeks postoperatively and antibiotic treatment w...

Few complications regarding the use of bioabsorbable suture anchors in the shoulder have been reported. What motivated this case report was the unusual location of the anchor, found in the acromioclavicular joint which, to our knowledge, has never been reported so far. A 53-year old male with previous rotator cuff (RC) repair using bioabsorbable suture anchors presented with pain and weakness a...

PURPOSE The aim of this randomized clinical trial was to radiographically compare peri-implant marginal bone level changes between immediately loaded implants without the removal of an abutment placed at the time of surgery (IL), delayed loaded nonsubmerged implants (NS), and delayed loaded submerged implants (SI). MATERIALS AND METHODS Patients' edentulous sites were randomly allocated to th...

Artificial drainage devices (ADD) create an alternative pathway for aqueous drainage from the anterior chamber of an eye through a tube to the subconjunctival bleb connected to an equatorial plate under the conjunctiva. The ADDs, both valved and non-valved, are available for end stage or refractory glaucoma. Currently, some of these devices, particularly the Express shunt, are recommended for t...

Treatment of polluting discharges from abandoned coal mines in the UK currently produces ca 30,000 t y(-1) of hydrous iron oxides ("ochre"), for which there is no major end-use, but which has previously been shown to have potential for removing P from wastewater and agricultural runoff. The efficiency of ochre for P removal from wastewater was investigated in experiments at two sites in the UK:...

Here we report a case of childhood glaucoma refractory to angle and trabeculectomy surgery. The patient was treated with an Ahmed™ drainage implant that was subsequently complicated by rapid-onset panophthalmitis and orbital cellulitis. Intravenous and intravitreal antibiotic therapy was initiated and the drainage tube was removed. The infectious process resolved within 3 weeks; however, phthis...

Orthotopic SBTx with ponocaval drainage l was perfonned with or without immunosuppression in 12 fully allogeneic rat strain combinations between LEW (RTI). BN (RT"). pva (RTle ). and ACI (RTla) rats (purchased from Harlan Sprague-Dawley Inc. Indianapolis. IN). For immunosuppression. FK 506 dissolved in HCO-60 and D-mannitol carrier solvent (gift from Fujisawa Pharm Co Ltd. Osaka. Japan) was giv...

Tobramycin sulphate, a new aminoglycoside antibiotic, was injected intramuscularly (80 and 100 mg) and subconjunctivally (10 mg) into patients, and the concentrations of the drug in serum and aqueous humour were determined 1 hour after the injection by an agar wall diffusion plate method. The intramuscular administration of tobramycin produced insignificant and non-inhibitory concentrations in ...
