Effects of hyaluronic acid on bleeding following third molar extraction

J. appl. oral sci; 25 (2), 2017
Abstract Objective To explore the effects of hyaluronic acid (HA) on bleeding and associated outcomes after third molar extraction. Methods Forty patients who had undergone molar extraction were randomly divided into two groups; 0.8% (w/v) HA was applied to the HA group (n=20) whereas a control group...

Caracterización de pacientes con cáncer colorrectal esporádico basado en la nueva subclasificación molecular de consenso

Rev. méd. Chile; 145 (4), 2017
Background: Colorectal cancer (CRC) is an heterogeneous disease. Three carcinogenic pathways determine its molecular profile: microsatellite instability (MSI), chromosomal instability (CIN) and CpG island methylator phenotype (CIMP). Based on the new molecular classification, four consensus CRC molecular...

Detection of herpes simplex-1 and -2 and varicella zoster virus by quantitative real-time polymerase chain reaction in corneas from patients with bacterial keratitis

Arq. bras. oftalmol; 80 (2), 2017
ABSTRACT Objective: Bacterial keratitis occurs worldwide, and despite recent developments, it remains a potentially blinding condition. This study assesses the presence of herpes simplex virus (HSV-1 and -2) and varicella zoster virus (VZV) by quantitative real-time polymerase chain reaction (qPCR) in c...

Comparisons of choroidal nevus measurements obtained using 10- and 20-MHz ultrasound and spectral domain optical coherence tomography

Arq. bras. oftalmol; 80 (2), 2017
ABSTRACT Purpose: To compare measurements of lesions clinically diagnosed as choroidal nevi using spectral domain optical coherence tomography (SD-OCT) and 10- and 20-MHz ultrasound (US). Methods: This prospective study, which was conducted between May 2011 and December 2011, evaluated eyes diagnosed w...

Incidence of anterior segment neovascularization during intravitreal treatment for macular edema secondary to central retinal vein occlusion

Arq. bras. oftalmol; 80 (2), 2017
ABSTRACT Purpose: To analyze the effects of injections of intravitreal triamcinolone acetonide (IVTA) and intravitreal bevacizumab (IVB) on the incidence rates of anterior segment neovascularization (ASN) and neovascular glaucoma (NVG) in patients with macular edema secondary to central retinal vein occ...

Keratoconus progression is not inhibited by reducing eyelid muscular force with botulinum toxin A treatment: a randomized trial

Arq. bras. oftalmol; 80 (2), 2017
ABSTRACT Purpose: To evaluate whether reducing eyelid muscular force through the administration of botulinum toxin type A (BTX-A) to the orbicularis oculi muscles of patients with keratoconus affected corneal parameters indicative of disease progression. Methods: In this prospective parallel randomized...

Accuracy of chest radiography for positioning of the umbilical venous catheter

J. pediatr. (Rio J.); 93 (2), 2017
Abstract Objectives: To evaluate the accuracy of the simultaneous analysis of three radiographic anatomical landmarks - diaphragm, cardiac silhouette, and vertebral bodies - in determining the position of the umbilical venous catheter distal end using echocardiography as a reference standard. Methods: ...

Comparison of Two Central Venous Pressure Control Strategies to Prevent Atrial Fibrillation After Coronary Artery Bypass Grafting

Arq. bras. cardiol; 108 (4), 2017
Abstract Background: Atrial fibrillation (AF) takes place in 10-40% of patients undergoing coronary artery bypass grafting (CABG), and increases cardiovascular mortality. Enlargement of atrial chambers is associated with increased AF incidence, so patients with higher central venous pressure (CVP) are e...
