Hemopneumotórax recorrente: descrição da síndrome da endometriose torácica / Recurrent hemopneumothorax: thoracic endometriosis syndrome description

A endometriose torácica é uma forma de endometriose extrapélvica encontrada em tecidos pulmonares ou na pleura. Caracteriza- se clinicamente pela presença de pneumotórax catamenial, hemotórax catamenial, hemoptise e nódulos pulmonares. O pneumotórax catamenial é a manifestação mais frequente, sendo caracterizado pelo acúmulo recorrente de ar na cavidade torácica durante o período menstrual. Ocorre, geralmente, no hemitórax direito e possui maior incidência na faixa etária dos 30 aos 40 anos de idade. Nosso objetivo é descrever um caso de derrame pleural hemorrágico recorrente e pneumotórax espontâneo correlacionados ao período menstrual em paciente de 34 anos. (AU)

Thoracic endometriosis is a form of extrapelvic endometriosis found in pulmonary tissue or the pleura. Clinically, it is characterized by the presence of catamenial pneumothorax, catamenial hemothorax, hemoptysis, and pulmonary nodules. The most frequent clinical presentation is catamenial pneumothorax, which is typified by a recurrent collection of air in the thoracic cavity occurring in conjunction with menstrual periods. It occurs more commonly on the right side and its highest incidence is between 30 and 40 years of age. Our objective is to describe a case of recurrent hemorrhagic pleural effusion and spontaneous pneumothorax correlated to the menstrual period in a 34-year-old patient. (AU)

Effects of different hormonal contraceptives in women's blood pressure values / Efectos de los distintos anticonceptivos hormonales en los valores de presión arterial de la mujer / Efeitos dos diferentes anticoncepcionais hormonais nos valores de pressão arterial da mulher

ABSTRACT Objective: To identify evidence in the literature of the relationship between the use of different hormonal contraceptive methods and alterations in women's blood pressure values. Method: This is an integrative literature review, consisting of ten scientific articles published in PubMed and BVS, between 2012 and 2016, selected by keywords, available fully and free of charge, in English, Portuguese, or Spanish. Results: The articles showed that exogenous estrogen helps in the activation of the renin-angiotensin-aldosterone system causing hypertensive effects even in small doses; and that combined use with drospirenone reduces these effects. Routes of administration without passage through the liver and use of isolated progestin showed promising results in reducing the effects on blood pressure. Conclusion: There is evidence in the literature of pressure alterations associated with different hormonal contraceptives and that personal history of morbidities are to be considered in an attempt to reduce the effects on the cardiovascular system.

RESUMEN Objetivo: Identificar en la literatura evidencias sobre la relación entre el uso de distintos métodos anticonceptivos hormonales y las alteraciones en los valores de presión arterial en mujeres. Método: Se trata de la revisión integrativa de la literatura, constituida por diez artículos científicos publicados en PubMed y BVS, entre 2012 y 2016, seleccionados por medio de palabras-clave, disponibles en su totalidad, gratuitos, en inglés, en portugués o en español. Resultados: Los artículos han enseñado que el estrógeno exógeno aporta en la activación del sistema renina-angiotensina-aldosterona causando efectos hipertensivos aunque en pequeñas dosificaciones; y que el uso combinado con la drospirenona reduce esos efectos. Vías de administración sin pasaje por el hígado y el uso del progestágeno aislado han enseñado resultados promisores en la reducción de los efectos sobre la presión. Conclusión: Hay evidencias en la literatura de alteraciones presóricas asociadas a distintos anticonceptivos hormonales y de que antecedentes personales de morbilidades deben ser considerados en el intento de reducir los efectos sobre el sistema cardiovascular.

Vias de administração sem passagem pelo fígado e uso do progestágeno isolado mostraram resultados promissores na redução dos efeitos sobre a pressão. Conclusão: Há evidências na literatura de alterações pressóricas associadas a diferentes anticoncepcionais hormonais e de que antecedentes pessoais de morbidades devem ser considerados na tentativa de reduzir os efeitos sobre o sistema cardiovascular.

Influence of hormonal contraceptives and the occurrence of stroke: integrative review / Influencia de anticonceptivos hormonales y acaecimiento de accidente vascular cerebral: revisión integradora / Influência de anticoncepcionais hormonais e ocorrência de acidente vascular cerebral: revisão integrativa

ABSTRACT Objective: To identify scientific evidence regarding the influence of hormonal contraceptive use and the occurrence of stroke. Method: Integrative review of the literature, through database search using the descriptors "contraceptive agents", "contraceptive devices", "contraceptives, Oral" and "Stroke". Original studies in Portuguese, Spanish and English, published in full and available online were included. Studies that did not answer our guiding questions and duplicated studies were excluded. Results: Women using combined oral contraceptives have higher risk of stroke, even with a lower hormonal dosage and different types of progestogen, regardless of the duration of use. The use of contraceptives associated with smoking, hypertension, migraine, hypercholesterolemia, obesity and sedentary lifestyle increases the chance of stroke. Contraceptive patch and vaginal ring are associated to increased risk. Conclusion: Use of combined hormonal contraceptives, except for the injectable and the transdermal ones, increases the chance of occurrence of the event. Progestogen-only contraceptives were considered safe.

RESUMEN Objetivo: Estudiar las evidencias científicas acerca de la influencia del uso de anticonceptivos hormonales en el acaecimiento de accidentes cerebrales vasculares (ACV). Método: Revisión integradora de la literatura, realizada mediante investigación científica en bases de datos, utilizando los descriptores "anticonceptivos", "dispositivos anticonceptivos", "anticonceptivos orales" y "derrame cerebral". Se incluyeron artículos originales en los idiomas portugués, español e inglés, publicados en su totalidad y disponibles electrónicamente. Se excluyeron los artículos repetidos y aquéllos que no respondían a las cuestiones orientadoras. Resultados: Las usuarias de anticoncepcional oral combinado presentan un riesgo mayor de ACV, inclusive con dosis hormonal menor y diferentes tipos de progestágeno, independientemente del tiempo de utilización. La presencia del tabaquismo, hipertensión arterial, jaqueca, hipercolesterolemia, obesidad y sedentarismo aumenta la probabilidad de ese desenlace. El adhesivo anticonceptivo y el anillo vaginal están relacionados con el aumento de ese riesgo. Conclusión: La utilización de anticonceptivos hormonales combinados aumenta la probabilidad del acaecimiento del evento, excepto con el inyectable y el transdérmico. Los exclusivos de progestágeno se consideran seguros.

Association between reproductive factors and breast cancer in an urban set up at central India: A case-control study.

Background: Epigenetic changes, geography and environmental factors do surpass the genetic factors in the development of breast cancer. This study investigates the association of reproductive factors with the breast cancer in this context. Objective: To detect the association of reproductive risk factors with breast cancer in an urban set up at central India. Study Design: Matched paired community-based case-control study. Materials and Methods: The study was conducted for a period of a year from October 2008 to August 2009 in Bhopal (MP). Demographic data and reproductive risk factor related information were collected using structured questionnaire. Data analysis was done by Epi-info and SPSS 16. Results: History of using oral contraceptive pills (OR = 3.02, 95% CI: 1.28-7.11), history of not having breastfeeding (OR = 3.62, 95% CI: 1.29-10.16) and family history of breast cancer (OR = 3.98, 95%CI: 1.06-14.826) were associated significantly with the occurrence of breast cancer in multivariate analysis. Conclusions: The findings of the present study suggests that positive family history of breast cancer and history of using OCP may be the epigenetic factors promoting the occurrence of breast cancer while breastfeeding reduces the possibility of acquiring breast cancer.

Tratamento hormonal da acne baseado em evidências / Hormonal treatment of acne based on evidence

Este trabalho de revisão apresenta o tratamento hormonal da acne baseado em evidências. O trabalho resume a clínica, a classificação, a fisiopatologia e a etiologia da acne. A avaliação de estudos selecionados mostrou que o tratamento hormonal da acne deve ser complementado por tratamento cosmiátrico, e não está indicado para gestantes ou mulheres com planos de engravidar. A primeira escolha para esse tratamento são os contraceptivos hormonais orais, pois são efetivos e seguros para tratamento da acne e também para anticoncepção. Após tempo estabelecido, se o resultado for insatisfatório, outro medicamento, como acetato de ciproterona ou espironolactona, deve ser adicionado. A finasterida é o medicamento indicado para acne de origem idiopática, e a flutamida apresenta efeitos colaterais significativos, não constituindo indicação segura até o momento.

This review shows the hormonal treatment of acne. The review summarizes the clinical aspects, classification, physiopathology and etiology of the acne. The evaluation of selected papers showed that hormonal treatment of acne with hormones has to be complemented by esthetics treatment and is not prescribed for pregnant women or those who want to get pregnant. The first choice of treatment is the hormonal oral contraceptive one, because it is effective and safe for treatment of acne and also for contraception. After an established period with unsatisfactory results, other medicines, such as ciproterone acetate or spironolactone, can be added. The finasteride is prescribed for idiopathic acne and flutamide has many relevant side effects and is also not safe.

Utilidad del sistema intrauterino liberador de levonorgestrel (Mirena) en el tratamiento de las metrorragias / Usefulness of the Releasing Intrauterine System of Levonorgestrel in treatment of metrorrhagia

El uso continuo de anticonceptivos hormonales activos mediante la inserción del sistema intrauterino liberador de progestágenos (Levonorgestrel) ha sido de gran utilidad, pues además de la deseada acción anticonceptiva se le añade un efecto positivo de utilidad para el manejo de algunas afecciones ginecológicas, como son la endometriosis, fibromatosis uterina y ciertas disfunciones menstruales, a los que se han ido agregando recientemente nuevas indicaciones. OBJETIVO: Evaluar la utilidad del SIU liberador de Levonorgestrel (Mirena) en el manejo de las metrorragias y otras afecciones ginecológicas. MÉTODOS: Se realizó un estudio prospectivo, longitudinal, descriptivo que incluyó a 19 pacientes a las que se les insertó Mirena con el propósito de tratar las metrorragias y otras afecciones ginecológicas, en el período de tiempo comprendido entre el 1º de enero de 2003 al 31 de diciembre de 2008. Las pacientes incluidas en el estudio se evaluaron semestralmente mediante interrogatorio, examen clínico, estudios hematológicos y ecografía. RESULTADOS: Encontramos una notoria reducción del flujo menstrual, aquellas con más de 12 meses de uso presentaron un incremento de 1 ¢ gr en las cifras iniciales de hemoglobina. Las pacientes con miomas lograron discreta reducción tumoral y control de las metrorragias en tanto se comprobó una reducción en las masas quísticas y los síntomas en las pacientes con endometriosis, en tanto logramos un endometrio lineal en las pacientes en terapia de reemplazo hormonal (TRH). CONCLUSIONES: Los efectos adversos más reportados fueron los relacionados a la acción local del progestágeno sobre el endometrio como son el spotting y la amenorrea, de forma excepcional se reportaron calambres en miembros inferiores, hasta la fecha ninguna usuaria ha interrumpido la utilización de Mirena

The continuous use of active hormonal contraceptives by insertion of intrauterine system releaser of progestational agent (Levonorgestrel) has been very useful due to its desired contraceptive action as well as its positive effect for managing of some gynecological affections including endometriosis, uterine fibromatosis and certain menstrual dysfunctions and adding recently new indications. OBJECTIVE: To assess the usefulness of the intrauterine releaser system Lovenorgestrel (Mirena) in management of metrorrhagies and other gynecological affections. METHODS: A descriptive, longitudinal and prospective study was conducted including 19 patients underwent Mirena insertion to treatment metrorrhagies and other gynecological affections between January 1, 2003 and December 31, 2008. Patients included in study were half-yearly assessed by interviews, clinical examination, hematology studies and echography. RESULTS: There was a market reduction of menstrual flux; those patients with more than 12 months of use had an increase of 1 ¢ gr in first figures of hemoglobin. Patients presenting with myomata achieved a slight reduction of tumor and a metrorrhagies control also verifying a decrease in cystic masses and in symptoms of patients with endometriosis, while it was possible to obtain a linear endometrium in patients under hormone replacement therapy (HRT). CONCLUSIONS: More frequently reported adverse effects were those related to local action of progestogen on endometrium e.g. spotting and amenorrhea. As exception were the lower extremities cramps. Until now no patient has interrupted the use of Mirena

Síndrome do ovário policístico: aspectos atuais das abordagens terapêuticas: parte 2 / Polycystic ovary syndrome: current aspects of the therapeutic interventions: part 2

A segunda parte desta revisão inclui as demais opções de tratamento da síndrome do ovário policístico (SOP). O citrato de clomifeno (CC) é utilizado na dose de 50 a 200 mg/dia durante cinco dias a partir do segundo ao quinto dia do ciclo menstrual. A taxa de ovulação após o tratamento com CC é de aproximadamente 73 por cento e a de gravidez em torno de 36 por cento. Com os análogos do GnRH ocorre redução dos níveis de gonadotrofinas e diminuição da secreção de estrógenos e androgênios. O principal risco da estimulação com gonadotrofinas é a gestação múltipla. Anastrazole e letrozole pertencem à classe dos inibidores da aromatase de terceira geração. As taxas de ovulação e gestação com letrozole variam de 54,5 a 82,4 por cento e 9 a 25 por cento, respectivamente. Não ocorreu diferença significativa nas taxas de ovulação e gestação entre o uso de 2,5 mg de letrozole em comparação com 1 mg de anatrozole. O uso da N-acetilcisteína (NAC) sugere melhora significativa da sensibilidade à insulina em mulheres com SOP. Os contraceptivos hormonais orais combinados permanecem como tratamento predominante para redução do hiperandrogenismo e das irregularidades menstruais em mulheres que não desejam engravidar. Os antiandrógenos são utilizados principalmente para diminuir as queixas de hirsutismo e o efeito será percebido em 9 a 12 meses de tratamento. Muitas mulheres se submetem à cauterização ovariana ou a laser por videolaparoscopia tendo restauração espontânea da ovulação com gravidez subsequente. Porém, os benefícios potenciais destas intervenções tendem a ser atenuados devido à formação de aderências.

The second part of this review includes other treatment options for polycystic ovary syndrome (PCOS). The clomiphene citrate (CC) is used in a dose of 50 to 200 mg/day for five days, begining from the second to fifth day or the menstrual cycle. The ovulation rate after the treatment with CC is approximately 73 percent and the pregnancy rate is about 36 percent. With GnRH analogues, there is a reduction in gonadotrophin levels and a decrease of androgen and estrogen secretion. The major risk due to stimulation with gonadotrophins is the multiple gestation. Anastrozole and letrozole belong to the class of third-generation aromatase inhibitors. The rates of ovulation and pregnancy with letrozole vary from 54.5 to 82.4 percent and from 9 to 25 percent, respectively. There was no significant difference in ovulation and pregnancy rates with the use of 2.5 mg of letrozole compared to 1 mg of anastrozole. The use of N-acetyl Cysteine (NAC) suggests significant improvement in insulin sensibility in women with PCOS. The combined oral hormonal contraceptives are still the predominant treatment to decrease hyperandrogenism and menstrual irregularities in women who do not want to get pregnant. Anti-androgens are used mainly to diminish complaints of hirsutism and the effect will be noted after 9 to 12 months of treatment. Several women undergo ovarian cauterization of with laser by videolaparoscopy having their ovulation spontaneously restored with subsequent pregnancy. However, the potential benefits of these interventions might be attenuated due to adhesion formations.

Conhecimento objetivo e percebido sobre contraceptivos hormonais orais entre adolescentes com antecedentes gestacionais / Objective and perceived knowledge of oral contraceptive methods among adolescent mothers

A elevada freqüência de gestação precoce no Brasil e, particularmente, em Teresina (21,5 por cento), Piauí, motivou o presente estudo, cuja meta foi identificar os níveis de conhecimento objetivo e percebido sobre contraceptivos hormonais orais, bem como variáveis reprodutivas e sócio-demográficas preditoras de elevado conhecimento. Realizou-se estudo transversal com 278 adolescentes com idade de 15 a 19 anos de idade, com antecedentes reprodutivos, internadas em quatro maternidades de Teresina, em 2006. Regressão logística foi a base da análise estatística. Quase 98 por cento das adolescentes apresentaram baixo conhecimento tanto objetivo quanto percebido. Apenas o maior número de gestações foi preditor de elevado conhecimento objetivo para anticoncepcionais orais. Os baixos níveis de conhecimento objetivo e percebido das adolescentes sobre o uso de anticoncepcionais orais revelam a suscetibilidade das jovens ao comportamento sexual de risco. Sugere-se a utilização de abordagem mais interativa com os adolescentes para elevar o nível de conhecimento tanto objetivo quanto percebido deles, e assim reduzir a incidência e reincidência da gravidez indesejada na adolescência e suas conseqüências negativas na vida destas jovens e de sua prole.

The high rate of early pregnancy in Brazil and particularly in Teresina (21.5 percent), Piauí State, motivated the current study, the aim of which was to identify levels of objective and perceived knowledge on oral contraceptives, as well as predictive reproductive and socio-demographic variables for high knowledge. A cross-sectional study was performed including 278 teenage mothers (15-19 years), with their childbearing history, admitted to four maternity hospitals in Teresina in 2006. Logistic regression provided the basis for the statistical analysis. Nearly 98 percent of the adolescent mothers showed low objective and perceived knowledge of oral contraceptives. High parity was the only predictor of increased objective knowledge on oral contraceptives. The adolescents' low level of objective and perceived knowledge on use of oral contraceptives emphasized their susceptibility to risky sexual behavior. The findings emphasize the need for a more interactive approach with adolescents concerning their level of objective and perceived knowledge, to reduce the occurrence and repetition of unwanted teenage pregnancy and its negative consequences for the lives of these young mothers and their children.

Métodos anticoncepcionais hormonais / Hormonal contraception methods

A orientação e a utilização da anticoncepção abrangem um grande período de vida da mulher, que vai do menacme à menopausa, atingindo vários segmentos de faixa etária. Nenhum método poderá satisfazer as necessidades de todas as mulheres nas diversas etapas de sua vida reprodutiva, pois variam quanto a: eficácia, efeitos secundários, formas de uso e custo. Assim, o aconselhamento sobre todos os métodos é indispensável para que as pessoas tomem decisões adequadas. Nos últimos anos ocorreram grandes avanços no conhecimento científico, em relação ao desenvolvimento e pesquisa de novos métodos contraceptivos hormonais. A Organização Mundial de Saúde, no sentido de facilitar e auxiliar os orientadores e prescritores de anticoncepção, elaborou uma classificação para adequar o uso dos métodos contraceptivos hormonais na presença de algumas condições (idade, paridade) ou de intercorrências clínicas, cirúrgicas ou ginecológicas. Os riscos e benefícios da utilização dos métodos contraceptivos foram avaliados de forma criteriosa, podendo auxiliar a opção mais adequada de contracepção.

Contraceptive counseling and its use are part of women's lives from menarche to menopause, thus spanning through a woman's lifetime. Since each method has a different profile in terms of effectiveness, collateral effects, usage and costs, no single contraceptive is expected to meet the demands of every woman throughout the various phases of her reproductive life. Therefore, contraceptive counseling is essential in assiting women make appropriate choices. In the last years there have been important scientific advances in the field of contraceptive research and development. In this context, the World Health Organization has created a classification that is useful to the people in charge of counseling and prescribing contraceptive methods. This classification takes into consideration some demographic variables (age, parity) as well as clinical, surgical and gynecological conditions. The risks and benefits of each contraceptive method have been carefully assessed, thus allowing a judicious choice to be made.

Effect of the oral contraceptive pill on patients undergoing controlled ovarian hyperstimulation

This is a retrospective analysis of 89 patients who were undergoing controlled ovarian hyperstimulation for in vitro fertilization and embryo transfer in the Fertility Management Unit of the Department of Obstetrics, Gynaecology and Child Health, The University of the West Indies. Twenty-eight patients (Group A), who did not receive oral contraceptive pills prior to controlled ovarian hyperstimulation (COH) were compared with 61 patients in Group B treated with oral contraceptive pills for two months prior to undergoing COH assisted reproduction using the long protocol. The number of follicles, oocytes, estimated oestradiol levels on the day of administration of human chorionic gonadotrophin (hCG), pregnancy rates, miscarriage rates and the incidence of patients who developed ovarian hyperstimulation syndrome (OHSS) were the main outcome measures. The mean age and haematocrit were the same in each group. The number of follicles retrieved tended to be higher in Group A than in Group B (median 8 versus 6, p = 0.06) with significantly more oocytes being retrieved in Group A than Group B (p < 0.05). There were no statistically significant differences between the two groups in oestradiol levels, the proportion of patients with polycystic ovarian disease, the proportion of women who developed ovarian hyper-stimulation syndrome or pregnancy outcomes. There was no difference between the groups in measures of clinical severity of OHSS. In a logistic regression model the significant predictors of OHSS were haematocrit and oestradiol levels. There appeared to be no significant clinical benefit in administering oral contraceptive pills for two months to patients prior to COH

Epilepsia y anticonceptivos / Epilepsy and contraceptives

La epilepsia es una enfermedad neurológica que puede afectar a la mujer en edad fértil. Es conocido que las terapias anticonvulsivantes pueden disminuir la efectividad de los anticonceptivos hormonales. Los principales mecanismos son una mayor estimulación del sistema enzimático hepático de la citocromo P450 y el aumento de los niveles de la globulina transportadora de hormonas sexuales. Como consecuencia se produce una disminución de los niveles disponibles de los anticonceptivos hormonales, debiendo ajustar las dosis y en algunas oportunidades utilizar otros métodos.

Endocrine characteristics of polycystic ovary syndrome (PCOS).

Polycystic ovary syndrome (PCOS) is probably the most prevalent endocrinopathy in women and the most common cause of anovulatory infertility. Patients with PCOS have clinical and biochemical features consistent with the ultrasound diagnosis and they are likely to face the problems of hyperandrogenism, subfertility and recurrent miscarriage. The aim of the present review is to summarize our present knowledge on the hormonal background of this very prevalent syndrome and to give some clinical examples how the present knowledge can be applied to treat PCOS patients according to their current problem, such as menstrual cycle disorder, hirsutism, infertility or to prevent late consequences as diabetes mellitus. The etiology and pathogenesis of PCOS is still a matter of controversies, but it is apparent that inappropriate gonadotropin secretion, obesity, hyperinsulinism and insulin resistance are the major determining factors in the development of ovarian hyperandrogenism an chronic anovulation. Reversal of insulin resistance in PCOS constitutes the fundamental goal in the management of hyperandrogenic anovulatory infertility and in the prevention of long-term consequences. The value of the insulin sensitizer metformin therapy awaits further evaluation and it should be integrated in the spectrum of therapeutical options that include the discussed surgical methods and GnRH analogues as well.

Trends in male contraception

Methods that are available for male contraception, namely coitus interruptus, condoms, and vasectomy, have been used since the 19th century. With the exceptions of a few improvements of these methods, no major progress has been made with respect to introducing new male contraceptives since then. It is extremely urgent to develop new, safe, effective, and reversible male contraceptive methods. Among all male contraceptive methods that are being investigated, the hormonal approach is the closest to clinical application. Hormonal contraception provides pregnancy protection by means of spermatogenic suppression. Androgen-progestin regimens currently represent the best available hormonal combination for induction of a profound suppression of spermatogenesis. Further development of new steroids is mandatory for increasing the choices of available contraceptive formulations and to optimize long-term safety of these regimens

Consenso acerca de la recuperación del ciclo mentrual y fertilidad posterior al uso de anticonceptivos hormonales / A consensus upon menstrual cyclo and fertility restoration after hormonal contraception

Se revisa la frecuencia de amenorrea y esterilidad a la suspención de anticonceptivos hormonales, concluyéndose que ésta es baja. Destaca que la población más susceptible de presentar alteraciones en este sentido es aquella con anteceentes de disfunción hipotálamo-hipofisaria

Endometrosis en adolescencia / Endometriosis in adolescents

Por mucho tiempo a la endometrosis no se la tenía en cuenta como diagnóstico diferencial en las mujeres menores de 20 años que padecían de dismenorrea o de dolor pelviano crónico. Aproximadamente la mitad de las adolescentes que padecen estos síntomas son portadoras de una endometrosis. La laparoscopia ha permitido un diagnóstico precoz y de certeza evitando que dicha enfermedad alcance estadios severos. A pesar de los avances producidos la endometrosis es aún de difícil diagnóstico privando a la adolescente del tratamiento adecuado para su dolor y haciendo peligrar su futuro reproductivo
