BACKGROUND Angiogenesis-related corneal blindness includes the spectrum of corneal diseases that are caused by pathological angiogenesis, leading to untoward visual impairment. The purpose of this study was to investigate the antineovascularization effect of topical silica nanoparticles (SiNPs) in inhibiting chemical-burn-induced corneal neovascularization. MATERIALS AND METHODS A total numbe...

AIM To compare the haemostatic effect and tissue reactions of different agents and methods used for haemorrhage control in apical surgery. METHODOLOGY Six standardized bone defects were prepared in the calvaria of six Burgundy rabbits. Five haemostatic modalities were tested for their haemostatic effect and tissue reactions, and were compared with untreated control defects: Expasyl + Stasis, ...

OBJECTIVES To describe the various presentations and management of piriform sinus tracts in children and to provide a treatment algorithm. DESIGN Case series. SETTING Pediatric otolaryngology service in a tertiary care setting. PATIENTS Eight pediatric patients diagnosed as having a piriform sinus tract between 1999 and 2005. INTERVENTIONS Patients were treated with surgical excision, e...

We evaluated the change in tear film lipid layer thickness, corneal thickness, volume and topography after superficial cauterization of symptomatic conjunctivochalasis. Bilateral superficial conjunctival cauterization was performed in 36 eyes of 18 patients with symptomatic conjunctivochalasis. The mean age of patients (12 males, 6 females) was 68.6 ± 10.9 years (range: 44-83 years). Preoperati...

OBJECTIVE This study aimed to compare the effects of hemocoagulase atrox and cauterization hemostasis on intimal hyperplasia and explore the effect of hemocoagulase atrox on vascular modeling in rabbit carotid artery adventitia. METHODS A total of 27 rabbits were randomly divided into 3 groups (0d, 14d, 28d). They were anaesthetized using an intramuscular injection of phenobarbital sodium (1 ...

Inverted papilloma is a common, benign sinonasal tumor with known high rate of recurrence. To prevent recurrences, complete excision inverted essential. In excision, especially, identifying the attachment site and managing meticulously important. this study, we introduce two surgical methods for that can reduce recurrence rate: prelacrimal approach ‘origin cauterization drilling (painting washi...

PURPOSE The principal risks of needle biopsy are hemorrhage and implantation of tumor cells in the needle tract. This study compared hemorrhage after liver and kidney biopsy with and without radiofrequency (RF) ablation of the needle tract. MATERIALS AND METHODS Biopsies of liver and kidney were performed in swine through introducer needles modified to allow RF ablation with the distal 2 cm o...

PURPOSE Inducible nitric oxide synthase (NOS-II) is expressed in many inflammatory conditions. The implication of nitric oxide (NO) in angiogenesis remains controversial. The role of NOS-II and its influence on angiogenesis in corneal neovascularization is unknown and was investigated in this study. METHODS A mouse model of corneal neovascularization induced by chemical cauterization was used...
