Introduction Vascular leiomyoma of the nasal cavity is an extremely rare tumor that represents less than 1% of all vascular leiomyomas. It is more prevalent in women between the fourth and sixth decades, reaching primarily the inferior nasal turbinates. Objectives Reporting and assisting the systematization of more accurate diagnostic methods in clinical(More)
Nasal polyposis (NP) is a chronic inflammatory disease of the nasal mucosa characterized by the infiltration of inflammatory cells, mainly eosinophils. Although nasal polyposis occurs in 4% of the population, its physiopathology remains unclear. The aim of this study was to identify and characterize differentially expressed genes that can be used in the(More)
The trypanocidal activities of cis-3-(4'-bromo[1,1'-biphenyl]-4-yl)- 3-(phenyl)-N,N-dimethyl-2-propen-1-amine (Vb) and cis-3-(4'-bromo[1,1'-biphenyl]-4-yl)-3-(4-bromophenyl)-N,N-dimethyl-2- propen-1-anine (Vg) appeared 6.3 and 3.5 fold more active than the trans-isomers, respectively. Multi-endpoints for toxicity were also applied. Neutral red uptake (NRU),(More)
UNLABELLED Glucocorticoids (GC) are the drugs of choice for the clinical treatment of nasal polyposis, according to the medical literature. Its mechanism of action in the regression of clinical symptoms and polyps, however, is not fully understood. The topical and/or systemic use of glucocorticoids lead to variable expression of cytokines, chemokines and(More)

Introduction Nasal obstruction is one of the main rhinologic complaints, and two diseases must be investigated as differential diagnosis: rhinosinusal polyposis and inverted papilloma. Using traditional methods, the differential diagnosis between these diseases may be difficult. The morphometric study may be a useful tool for differential diagnosis and to(More)
UNLABELLED Rhinosinusal polyps physiopathology is not fully understand, despite numerous hypotheses regarding its inflammatory process. AIMS A prospective study regarding the gene expression of proteins: anexin-1 and galectin-1, which has an anti-inflammatory action and is modulated by steroids. MATERIALS AND METHODS Eleven patients with rhinosinusal(More)
Oncogenic human papillomavirus (HPV), a causative agent of uterine cervical cancer, has also been detected in head and neck squamous cell cancers, especially in squamous cell carcinomas of the tonsils. However, the true HPV prevalence in normal and neoplasic oropharyngeal mucosa remains uncertain. To determine the prevalence of HPV DNA in normal(More)
BACKGROUND Rhinosinus polyposis, characterized by a degeneration of the nasal mucosa of the middle meatus, is poorly understood but probably is correlated with several clinical and etiopathogenic entities. Although not definitely characterized, infectious, atopic, inflammatory, genetic, and other factors are involved. The occurrence of malignant(More)
