This paper presents color image processing methods for the analysis of dermatological images in the context of a content-based image retrieval (CBIR) system. Tests were conducted on the classification of tissue components in skin lesions, in terms of necrotic tissue, fibrin, granulation, and mixed composition. The images were classified based on color(More)
INTRODUCTION American tegumentary leishmaniasis (ATL) represents one of the most important public health issues in the world. An increased number of autochthonous cases of ATL in the Northeastern region of São Paulo State has been documented in the last few years, leading to a desire to determine the Leishmania species implicated. METHODS PCR followed by(More)
INTRODUCTION: Plaque-type psoriasis affecting the nails, scalp, hands or feet can often be difficult to treat; for example, topical treatments and phototherapy may not penetrate the nail plate or scalp. The objective of this large, international, multicentre study was to investigate the efficacy of efalizumab in a Latin American population of adult patients(More)
The diagnosis of American Tegumentary Leishmaniasis is a difficult but essential task when considering the high toxicity profile of the drugs available. Since the discovery of its etiologic agent, numerous diagnostic tests have been developed. None of the tests available today can be considered as the gold standard, since they do not add enough accuracy for(More)
Background.  Disseminated leishmaniasis (DL) is an emerging clinical form of American tegumentary leishmaniasis (ATL) that occurs mainly in Northeastern Brazil. This study describes 18 cases where DL has not yet been reported. Methods.  Disseminated leishmaniasis cases were extracted from ATL recorded cases between 1987 and March 2015. Disseminated(More)
BACKGROUND Endemic pemphigus foliaceus (EPF) is the only known autoimmune disease presenting in circumscribed geographic areas. AIM We aim to provide information concerning the natural course of EPF, including systemic compromise in the presteroid era, which has been largely unavailable in the current medical literature. MATERIAL #ENTITYSTARTX00026; (More)
BACKGROUND Maxadilan (Max) is a salivary component in the sandfly Lutzomyia longipalpis (Lutz & Neiva 1912), a vector of visceral leishmaniasis. Max has a powerful vasodilatory effect and is a candidate vaccine that has been tested in experimental leishmaniasis. Nyssomyia neivai (Pinto 1926) is a vector of the pathogen responsible for American tegumentary(More)
Pemphigus are blistering autoimmune diseases related with genetic and environmental factors. Here we describe HLA genotyping in pemphigus patients. First, we review the HLA class I/II data on pemphigus reported in Brazilian samples and then present the HLA class I (-A, -B, -C) and class II (-DRB1, -DQA1, -DQB1) alleles related to susceptibility/resistance(More)
Discrepancies in the terminology of elementary lesions persist when texts from Dermatology and Semiology books are compared, which can cause some confusion in both the teaching of undergraduate medical students and the learning acquired by professionals in the field. This review aims to compare and clarify the differences in the description of elementary(More)
Distinct cases of Paracoccidioidomycosis and Cryptococcosis with atypical and localized skin manifestation on the upper limbs of two elderly patients are reported. In the 2nd one, he presented asymptomatic pulmonary cancer; the blood tests for fungal infection were negative, and the etiologic agents were seen in skin biopsy samples. This report emphasizes(More)
