RESUMO
Although fractures had high mortality and morbidity, many studies proved that fracture risk might be decreased by pharmacological therapy, although a low treatment adherence rate is observed. The aim of this study was to identify factors associated with osteoporosis treatment in postmenopausal women.A cross-sectional study was carried out from March to August 2013 at the primary care setting. Postmenopausal women were recruited. A standardized questionnaire was applied. Women who were using at least one of the following drugs at the moment of the survey were considered as current treatment: bisphosphonates, raloxifene, estrogen, calcitonin, teriparatide, or strontium ranelate. Women who had used any of the mentioned medications before the study were considered as past treatment.Of the 1025 women included in the study, 8% were on current treatment, 5.7% had past treatment, and 86.3% had not received treatment. Treated women (either current or past) had a higher rate of osteoarthritis, had more falls, had higher education level, presented a higher rate of private health insurance, and received more information about osteoporosis. They also had more dual-energy x-ray absorptiometry (DXA) scans and were more frequently diagnosed with osteoporosis by these DXA scans. The factors independently associated with treatment in the regression analysis were the DXA scan itself, the diagnosis of osteoporosis by DXA, and information about osteoporosis.Current and past treatments of osteoporosis were associated with DXA and information. These results suggest that some measures to inform women about osteoporosis and or even the popularization of DXA scans could improve the treatment.

ABSTRACT INTRODUCTION: Many epidemiological studies have suggested that human papillomavirus (HPV), especially type 16, is involved in the genesis of squamous cell carcinoma of the oral cavity and oropharynx, especially in young, non-smoking patients; thus, its detection in lesions in this region is important. OBJECTIVE: To clarify the capacity of the brushing sampling method to detect the presence of HPV in oral or oropharyngeal lesions through polymerase chain reaction (PCR) testing, and to compare the results with those obtained by biopsy. METHODS: Prospective study of adult patients with oral or oropharyngeal lesions assessed by PCR, comparing biopsy specimens with samples obtained by the brushing method. The study was approved by the Research Ethics Committee of the institution. RESULTS: A total of 35 sample pairs were analyzed, but 45.7% of the brushing samples were inadequate (16/35) and, thus, only 19 pairs could be compared. There was agreement of results in 94.7% (18/19) of the pairs, with HPV identified in 16 of them. HPV DNA was detected in 8.6% (3/35) of biopsy and 5.7% (2/35) of brushing samples. CONCLUSION: There was no statistically significant difference between the two methods, but the brushing sampling method showed a higher number of inadequate samples, suggesting that it is an unreliable method for surveillance.
Resumo INTRODUÇÃO: Muitos estudos epidemiológicos indicam a participação do papilomavírus humano, especialmente o tipo 16, na carcinogênese dos tumores espinocelulares das cavidade oral e oro-faríngea, principalmente em jovens e não fumantes, sendo portanto importante sua detecção nas lesões desta região. OBJETIVO: Elucidar a habilidade do escovado em detectar o papilomavírus humano, pela reação em cadeia da polimerase, nas lesões orais e orofaríngeas, comparando os resultados com os obtidos por biópsia. MÉTODO: Estudo prospectivo de pacientes com lesões orais e orofaríngeas, pela reação em cadeia da polimerase, no qual foram pareados os resultados de amostras obtidas por escovado e por biópsia. A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa da instituição. RESULTADO: Foram analisados 35 pares de amostras, porém estavam inapropriadas para análise 45,7% (16/35) das amostras obtidas por escovado, e portanto, somente 19 pares puderam ser comparados. Em 94,7% dos pares houve concordância dos resultados, sendo encontrado o papilomavírus humano − 16 em um destes pares. O ácido desoxirribonucleico do papilomavírus humano foi detectado em 8,6% (3/35) das biópsias e em 5,7% (2/35) dos escovados. CONCLUSÃO: Não houve diferença estatística entre os métodos, mas como houve um grande número de amostras obtidas por escovado inapropriadas, este parece não ser confiável para o rastreamento.

INTRODUCTION: Some clinical trials revealed a correlation between increased serum estrogen and nasal symptoms or inflammatory changes in nasal mucosa. Estrogen receptors tend to be controlled by a negative feedback, to avoid a deleterious stimulus over several body functions while in hyperestrogenic periods. This study proposes a hypothesis where mechanisms regulating expression of estradiol receptors in nasal mucosa are absent in some patients, and their concentration remains steady even in periods of high serum hormonal concentration, potentially leading to local estrogenic symptoms in nasal mucosa. STUDY DESIGN: This was an experimental prospective study. AIM: To determine whether estrogen levels induce the reduction of the number of estrogen receptors in the nasal mucosa. METHODS: In the present study, 30 adult male guinea pigs were subjected to a biopsy of the middle nasal turbinate and received 0.5 mL of estradiol cypionate intraperitoneally for 30 consecutive days. Afterwards, samples from contralateral middle turbinate were obtained. Immunohistochemical analysis of estrogen receptors were performed pre- and post-treatment. RESULTS: The post-treatment group showed reduction of receptor expression when compared to the pre-treatment group. (p = 5.2726-5). CONCLUSION: A reduction in the expression of the nasal estrogen receptor was observed after 30 days of estradiol administration.

Introdução: A literatura indica uma correlação entre estrogênio elevado no soro e sintomas nasais ou alterações inflamatórias na mucosa nasal. Os receptores de estrogênio tendem a ser controlados por retroalimentação negativa, para evitar um estímulo nocivo sobre as diversas funções corporais em períodos de hiperestrogenismo. Propomos uma hipótese em que os mecanismos que regulam a expressão de receptores de estradiol na mucosa nasal estão ausentes em alguns pacientes, e a sua concentração permanece estável mesmo em períodos de elevada concentração sérica hormonal, o que pode conduzir a sintomas locais na mucosa nasal. Desenho do estudo: Estudo prospectivo experimental. Objetivo: Determinar se altos níveis de estrogênio induzem à redução no número de receptores de estrogênio na mucosa nasal. Material e método: Trinta cobaias foram submetidas à biópsia da concha nasal, recebendo 0,5 ml de cipionato de estradiol por via intraperitoneal por trinta dias consecutivos. Em seguida foram obtidas amostras da concha nasal contralateral. As análises imuno-histoquímicas dos receptores de estrógeno foram realizadas antes e depois da hormonioterapia. Resultados: O grupo pós-tratamento mostrou uma redução da expressão dos receptores (p = 5,2726-5). Conclusão: Redução na expressão do receptor de estrogênio nasal foi encontrada após trinta dias de administração de estradiol. .

UNLABELLED: Knowledge about HPV infection in the oral cavity/oropharynx may contribute to the elucidation of the role it plays in Head and Neck Squamous Cell Carcinoma (HNSCC). OBJECTIVE: To determine the effectiveness of the methodology used for sampling the oral cavity and oropharynx mucosae and to determine the prevalence of HPV in the oral cavity and oropharynx of adults and children. METHOD: The study population was served by an assistance program in a rural district of São Paulo. The subjects were asked to donate samples regardless of complaints. RESULTS AND CONCLUSION: The study included 47 men, 77 women and 22 children, of which the oral cavity samples were obtained by gargling with commercially-available antiseptic mouthwash. We found 3 positive samples (2.4%) in adults: 2 HPV 55 and one HPV 58. No positive results were found in children. Furthermore we concluded that the sampling method with the mouthwash proved effective and fast for the detection of HPV in the oral cavity and oropharynx in the general population.

PURPOSE: To evaluate the impact of hysterectomy on the sexuality of women with uterine leiomyoma. METHODS: Prospective study including 33 sexually active women, with ages from 35 to 50 years old, with orgasmic experience and with a fit stable partner. All the women were submitted to two instruments for the evaluation or their sexuality: Sexual Quotient - Female Version (SQF) and Sexual Satisfaction Inventory - Female Version (SSIF). Both instruments were applied by the same examiner, before and six months after the hysterectomy. RESULTS: The SQF has shown that 39.4% of the patients presented deterioration in the sexual intercourse, even though there has not been found an association between the SQF results before and after hysterectomy (chi2= 0.6; degree of freedom=12; p=0.05). The mean scores obtained after the application of the SSIF have shown significant deterioration in the following parameters: sexual satisfaction (p=0.03); expression of feminine sensuality (p=0.01); vaginismus/dyspareunia (p=0.02) and an orgasmia (p=0.04). CONCLUSIONS: It seems that hysterectomy has a negative impact on women's sexual life, with reports of decreased libido, arousal and orgasmic capacity.

OBJETIVO: avaliar o impacto da histerectomia sobre a sexualidade de mulheres portadoras de leiomioma uterino. MÉTODOS: estudo prospectivo, no qual foram incluídas 33 mulheres sexualmente ativas, com idade de 35 a 50 anos, experiência orgástica e parceiro fixo capacitado para o coito. Todas as mulheres foram submetidas a dois instrumentos para avaliação da sexualidade: Quociente Sexual - Versão Feminina (QS-F) e Inventário de Satisfação Sexual - Versão Feminina (GRISS). Os mesmos instrumentos foram aplicados pelo mesmo examinador antes da histerectomia e seis meses após o procedimento. RESULTADOS: o QS-F apontou que 39,4 por cento das pacientes apresentaram piora no relacionamento sexual, apesar de não ter sido encontrada associação entre os resultados obtidos no QS-F antes e depois da histerectomia (χ2=10,6; grau de liberdade=12; p=0,05). Os escores médios obtidos após a aplicação do questionário de GRISS mostraram piora significante nos parâmetros "satisfação sexual" (p=0,03); "expressão da sensualidade feminina" (p=0,01); "vaginismo/dispareunia" (p=0,02) e "anorgasmia" (p=0,04). CONCLUSÕES: a histerectomia parece impactar negativamente a vida sexual das mulheres, sendo referida pela diminuição do desejo, da excitação e da capacidade orgásmica.

OBJECTIVE: to evaluate the expression of aromatase in simultaneously invasive ductal carcinoma (IDC) and ductal carcinoma in situ (DCIS). METHODS: forty-five surgical samples were obtained from mastectomy and quadrantectomy with simultaneous IDC and DCIS of stage I and II patients. Aromatase was evaluated using antibodies anti-aromatase and the samples classified in accordance with the number and intensity of stained cells. RESULTS: Aromatase was expressed positively in 32(71%) and negatively in 13(29%) of the cases in the IDC. The same results were obtained in the DCIS showing a perfect positive correlation. In the normal epithelium,aromatase was positive in 19(42.2%) and negative in 26 (57.8%) and a positive correlation, statistically significant was obtained when compared with IDC and DCIS(p<0.01). Concerning the normal stroma, positivity was only 7 (15.5%) showing no correlation with aromatase expression. Aromatase was positive in 36(80%) of the tumor stroma and this result was statistically significant as in the IDC and DCIS. Comparing results of aromatase expression with nuclear grade, histological grade, tumor size and age no difference was found. CONCLUSION: our results demonstrated high correlation between aromatase expression in IDC, DCIS, normal epithelium and tumor stroma showing a possible autocrine and paracrine mechanism of this enzyme in breast cancer.
