SUMMARY OBJECTIVE: This study aims to investigate the association between the immunohistochemical expression of matrix metalloproteinase-2 and matrix metalloproteinase-9 and plasma zinc in women with fibroadenoma. METHODS: This cross-sectional study included 37 premenopausal women with fibroadenoma. Waist circumference and body mass index of the participants were measured. Plasma zinc concentrations were determined using atomic flame absorption spectrophotometry. Fragments of breast tissue were fixed and incubated with primary mouse monoclonal antibodies (monoclonal antibodies matrix metalloproteinase -2 -507 and monoclonal antibodies matrix metalloproteinase -9-439). Semi-quantitative analysis of matrix metalloproteinase-2 and matrix metalloproteinase-9 immunoreactivity was performed. Spearman’s test and Friedman’s test were used for statistical analyses. The p

SUMMARY Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine disorder with variable prevalence, affecting about one in every 15 women worldwide. The diagnosis of polycystic ovary syndrome requires at least two of the following criteria: oligoovulation and/or anovulation, clinical and/or biochemical evidence of hyperandrogenism and morphology of polycystic ovaries. Women with PCOS appear to have a higher risk of developing metabolic disorders, hypertension and cardiovascular disorders. The aim of this article was to present a review of the literature by searching the databases Pubmed and Scielo, focusing on publications related to polycystic ovaries, including its pathogenesis, clinical manifestations, diagnosis and therapeutic aspects, as well as its association with cardiovascular and arterial hypertensive disorders. RESUMO A síndrome dos ovários policísticos (SOP) é uma desordem endócrina heterogênea com prevalência variável, que afeta cerca de uma em cada 15 mulheres no mundo. O diagnóstico da SOP requer, pelo menos, dois dos seguintes critérios: oligo-ovulação e/ou anovulação, evidência clínica e/ou bioquímica de hiperandrogenemia e morfologia dos ovários policísticos. As mulheres com SOP parecem ter um risco mais elevado de desenvolver distúrbios metabólicos, hipertensão e doenças cardiovasculares. O objetivo deste artigo foi apresentar uma revisão da literatura por meio de pesquisa nas bases de dados PubMed e Scielo, focada em publicações relacionadas com ovários policísticos, incluindo patogênese, manifestações clínicas, diagnóstico e aspectos terapêuticos, bem como associação com doenças cardiovasculares e hipertensão arterial.
