BACKGROUND Making diagnoses in oral pathology are often difficult and confusing in dental practice, especially for the less-experienced dental student. One of the most promising areas in bioinformatics is computer-aided diagnosis, where a computer system is capable of imitating human reasoning ability and provides diagnoses with an accuracy approaching that(More)
BACKGROUND AND AIM Proximal colorectal cancer may arise from sessile serrated adenomas (SSAs). Recognition of these lesions during colonoscopy can optimize the endoscopic approach. We aimed to identify specific endoscopic features of SSA with conventional colonoscopy. METHODS Patients undergoing screening colonoscopies from January 2011 to September 2012,(More)
Climatic droplet keratopathy (CDK) is a degenerative corneal disease of unknown etiology. We described CDK for the first time in Latin America in the Argentinean Patagonia (El Cuy). A deeper knowledge of CDK pathogenic mechanisms will provide new therapeutic strategies. For that reason we investigated the prevalence of CDK in El Cuy and its existence in(More)
BACKGROUND Conjunctival amyloidosis is a very rare condition, generally unilateral, and presents mostly as an isolated condition without systemic compromise. Our purpose is to present a new case of systemic amyloidosis with a bilateral conjunctival involvement. CASE PRESENTATION A 66-years-old caucasian female complaining of conjunctival hemorrhage and(More)
Three new species of Melanophryniscus are described from the Serra do Mar mountain range of the state of Santa Catarina, southern Brazil. All species are found at intermediate to high altitudes and share phytotelm-breeding as their reproductive strategy. The new species are distinguished from other phytotelm-breeding Melanophryniscus based on different(More)
Climatic droplet keratopathy (CDK) is an acquired degenerative disease predominantly affecting males over 40 years old. It results in progressive corneal opacities usually affecting both eyes. CDK is multifactorial and its etiology remains unknown. Our recent findings are consistent with CDK pathology being driven by environmental factors with oxidative(More)
Microorganisms abound everywhere. Though we know they play key roles in several ecosystems, too little is known about how these complex communities work. To act as a community they must interact with each other in order to achieve such community stability in which proper functions could help to adapt and survive to unbearable conditions. Thus, to eectively(More)
The eye and skin may offer critical clues to the diagnosis of a varied spectrum of metabolic diseases from endocrine origin and their different stages of severity, such as diabetes mellitus and Graves disease. On the other hand, such entities may compromise the eye and visual function severely, and awareness of these possible associations is an important(More)

Mountains of the Brazilian Atlantic Forest can act as islands of cold and wet climate, leading to the isolation and speciation of species with low dispersal capacity, such as the toadlet species of the genus Brachycephalus. This genus is composed primarily by diurnal species, with miniaturized body sizes (<2.5 cm), inhabiting microhabitats in the leaf(More)
