We examined the presence of human papillomavirus (HPV) DNA in 65 cases of laryngeal squamous dysplasia and carcinomas using in situ hybridization with signal amplification in paraffin sections. Hybridization was performed with biotinylated DNA probes for HPV 6/11, 16/18, 31/33 and wide-spectrum HPV (6, 11, 16, 30, 31, 45, 51 and 52). HPV DNA was found in 7(More)
BACKGROUND Giant cell collagenoma (GCC) is a recently described cutaneous fibrous neoplasm that usually affects young to middle-aged adults. Despite its similar histological appearance with circumscribed storiform collagenoma, no association of GCC with Cowden's syndrome has been described so far. To the best of our knowledge only five cases of this rare(More)
Schistosomiasis mansoni is found in different endemic areas of Brazil. It is a serious public health problem in Brazil and worldwide. Ectopic forms of the disease may affect the female reproductive system, representing a rare type of Schistosoma mansoni infection. A 26-year-old patient complained of vaginal discharge, dyspareunia and pain on palpation of(More)
Reverse engineering techniques are usually applied to extract concrete architecture models. However, these techniques usually extract models that just reveal static architectures, such as class diagrams. On the other hand, the extraction of dynamic architecture models is particularly useful for an initial understanding on how a system works or to evaluate(More)
Polymyositis (PM) is a systemic disease of the idiopathic inflammatory myopathy group, clinically characterized by symmetric and proximal muscle weakness. There are reports in literature of PM associated with malignancies, autoimmune diseases, and viral infections. However, the association between PM and nephropathy is not common. We describe a case report(More)

Currently, the management of urban waste streams in developing countries is not optimized yet, and in many cases these wastes are disposed untreated in open dumps. This fact causes serious environmental and health problems due to the presence of contaminants and pathogens. Frequently, the use of specific low-cost strategies reduces the total amount of(More)
Introduction: According to the guidelines, the viral load of 2,000 IU/mL is considered the level to differentiate between inactive carriers and HBeAg(-) chronic hepatitis B patients. Even so, liver damage may be present in patients with lower viral load levels, mainly related to regional variations. This study aims to verify the presence of liver injury in(More)
