The mol-ecular framew...

During this semester, ten reactions were carried out. The first was the synthesis of D-glyceraldehyde acetonide from D-mannitol. The next six reactions were involved with the synthesis of the corresponding γ-lactone of glyceraldehyde acetonide. The final three reactions were attempted syntheses of ethyl ethynyl ether, the key starting material in the synthesis of TMS ketene. Introduction In the...

Aim To evaluate the clinical effectiveness of combined oral propranolol with intralesional injection of triamcinolone acetonide in the treatment of infantile periorbital capillary hemangioma. Patients and Methods This prospective interventional study included children diagnosed with periocular infantile hemangiomas in the proliferative phase with vision-threatening lesions. The children prese...

OBJECTIVE To investigate the ability of high resolution grey scale sonography (GSS) and power Doppler sonography (PDS) to assess short term soft tissue changes induced by intra-articular steroid injection in the small joints of patients with chronic synovitis. METHODS 20 patients with clinically active synovitis of a small joint unresponsive to systemic drug treatment underwent a sonographic ...

In a comparative study concerning the effect of corticosteroids on host resistance to infections, five compounds were found to decrease host resistance, while three did not have this property, although all eight compounds were highly antiinflammatory. The compounds capable of decreasing host resistance were (I) hydrocortisone acetate; (III) 9alpha-fluoro, 16alpha-methylprednisolone acetate; (IV...

BACKGROUND This study aimed to investigate the effects of injection site on the reflux after intravitreal injection. METHODS One hundred and eighty eyes undergoing intravitreal injection including 0.1 ml of triamcinolone acetonide or bevacizumab or pegaptanib were divided to six groups (30 patients in each group) to compare the vitreal reflux after injection using superotemporal versus infero...

OBJECTIVE To evaluate the clinical outcome of an intravitreal injection of triamcinolone acetonide as treatment of diffuse diabetic macular edema. PARTICIPANTS This prospective, interventional, clinical case series study included 20 patients (26 eyes) who received an intravitreal injection of 25 mg of triamcinolone acetonide for treatment of diffuse diabetic macular edema. Mean +/- SD follow-...

PURPOSE To evaluate treatment of macular edema associated with central retinal vein occlusion (CRVO) using intravitreal triamcinolone acetonide. METHODS Retrospective review of data for 29 eyes of 29 patients with CRVO and macular edema treated with intravitreal triamcinolone acetonide. Initial visual acuity, intraocular pressure, and history of glaucoma were recorded. Final visual acuity, in...

Purpose: To evaluate the inflammatory response in the choroid, retina and vitreous in rabbit eyes underwent cryotherapy followed by intravitreal triamcinolone acetonide and to compare with those underwent cryotherapy followed by intravitreal injection of saline solution. Methods: This is a prospective case-control study. Surgical procedures were performed in eleven rabbits. Two animals were exc...
