OBJECTIVE To characterize histopathologic features of leaking mitomycin C-treated blebs and aberrant wound healing that may lead to persistent conjunctival thinning and leakage. METHODS Forty mitomycin C-treated filtering blebs excised for persistent leaks from 40 patients were examined histopathologically using hematoxylin-eosin, periodic acid-Schiff, Masson trichrome, and Alcian blue histoc...

AIMS To determine the presence and origin of myofibroblasts in pterygia. METHODS 86 specimens including head, body, and fibrovascular tissue from 52 primary and 34 recurrent pterygia and five exenterated eyes without pterygia were searched for the origin of myofibroblasts. All tissues were subjected to haematoxylin and eosin staining, immunohistochemistry using antibodies against alpha smooth...

PURPOSE To evaluate the local safety of bevacizumab and its effect on recurrence of primary pterygium excision. METHODS This randomized, placebo-controlled clinical trial was conducted on 44 eyes of 44 patients randomized to Group 1 (bevacizumab) and Group 2 (balanced salt solution). Group 1 underwent pterygium excision with a rotational conjunctival flap and received a total of 7.5 mg subcon...

We investigated the implant-bone interface around one design of femoral stem, proximally coated with either a plasma-sprayed porous coating (plain porous) or a hydroxyapatite porous coating (porous HA), or which had been grit-blasted (Interlok). Of 165 patients implanted with a Bimetric hip hemiarthroplasty (Biomet, Bridgend, UK) specimens were retrieved from 58 at post-mortem. We estimated ing...

This study was designed to explore the prevalence of fibrovascular proliferation not regressed in zone II stage 3 retinopathy of prematurity (ROP) after initial intravitreal ranibizumab (IVR) injections and to explore the possible influence factors. Fifty-seven patients (108 eyes) with ROP who underwent intravitreal injection of ranibizumab between January 2013 and July 2014 participated in the...

Background. Ultrasound (US) is the most accurate tool in the diagnosis of thyroid nodules if performed by expert physician. Misdiagnosis due to extrathyroidal lesions mimicking thyroid nodules is reported in literature. We describe the first case of an esophageal fibrovascular polyp misdiagnosed as a thyroid nodule on US examination. Patient Findings. A 54-year-old woman presented to emergency ...
