The association between follicular size at the time of spontaneous rupture and pregnancy rates in clomiphene citrate treated PCOS patients in coit cycles.

OBJECTIVE: To investigate the follicular size at spontaneous rupture on pregnancy rate in patients with polycystic ovary syndrome (PCOS) undergoing clomiphene citrate (CC) ovulation. DESIGN: Cross-sectional study. PATIENTS AND METHODS: One hundred and four women with ovulatory cycles after use of CC followed by ultrasound to determine the follicle size at the time of rupture, which was subsequently correlated with the occurrence of pregnancy or not in coit cycles. RESULTS: In the group of follicular rupture at a mean diameter ≤25 mm (n = 54), pregnancy rate was 35.1% and when follicular rupture occurred at a mean diameter >25 mm (n = 50), it was 34% (p > 0.05). When different diameters at follicular rupture were randomly correlated with the pregnancy rate, there was no significant difference. CONCLUSION: Our data suggest that the occurrence of pregnancy after ovulation induction with CC in women with PCOS is not associated with follicle size at the time of rupture.

[Sclerosing stromal tumor of the ovary associated with a Meigs' syndrome and pregnancy: a case report]. / Tumor estromal esclerosante de ovário associado à síndrome de Meigs e gestação: relato de caso.

The sclerosing stromal tumor of the ovary is an extremely rare benign tumor more common in young women and without specific symptoms in most cases. Less than 150 cases have been described, of which 8 were diagnosed during pregnancy. In this report, we describe the association between sclerosing stromal tumor of the ovary, Meigs' syndrome and elevated levels of CA-125 in term pregnancy.

O tumor estromal esclerosante de ovário é uma neoplasia benigna extremamente rara, mais frequente em mulheres jovens e sem sintomas específicos na maioria dos casos. Menos de 150 casos foram descritos, dos quais 8 diagnosticados durante a gestação. Neste relato, documentamos a associação entre tumor estromal esclerosante de ovário, síndrome de Meigs e elevação dos níveis de CA-125 em gravidez a termo.

Hormônio antimülleriano para avaliação da reserva ovariana: estado de arte / Anti-Müllerian hormone for ovarian reserve evaluation: state of art

A aferição do hormônio antimülleriano na clínica reprodutiva tem sido realizada com o objetivo de propiciar predição mais fidedigna da reserva folicular ovariana, por ser marcador indireto da quantidade e da qualidade de folículos primordiais. A correlação significativa com a contagem de folículos antrais, a quantidade e a maturidade de oócitos obtidos em técnicas de reprodução assistida têm ficado repetidamente evidentes na literatura, motivo pelo qual, acreditam os autores em um futuro cada vez mais promissor, que o hormônio venha a atuar como marcador propedêutico na avaliação e no prognóstico da paciente infértil. Neste artigo, pretende-se discutir informações atuais sobre o papel desse marcador para avaliação da reserva ovariana em candidatas a técnicas de reprodução assistida.

Measurement of anti-Müllerian hormone has been done in the practice of reproductive medicine for a more accurate prediction of ovarian follicular reserve, being an indirect marker of the quantity and quality of primordial follicles. A significant correlation with antral follicle count, the amount and maturity of oocytes in assisted reproductive techniques have been repeatedly evident in the literature, which is why we believe in the increasingly promising future of this hormone as a marker for the early assessment and prognosis of the infertile patient. In this article, we discuss current information on the role of the marker in the assessment of ovarian reserve in candidates for assisted reproduction techniques.

Ovarian reserve assessment for infertility investigation.

The current trends to postpone motherhood and the increase in demand for assistance in reproductive medicine highlight the need for seeking guidelines for the establishment of individualized treatment protocols. Currently available ovarian reserve tests do not provide sufficient evidence to be solely considered ideal, but they may occupy important place in initial counseling, predicting unsatisfactory results that could be improved by individualized induction schemes and reducing excessive psychological and financial burdens, and adverse effects. In this paper, we revise the role of hormonal basal and dynamic tests, as well as ultrasonographic markers, as ovarian reserve markers, in order to provide embasement for propaedeutic strategies and their interpretation in order to have reproductive success.

IVF/ICSI outcomes after culture of human embryos at low oxygen tension: a meta-analysis.

BACKGROUND: Improved pregnancy, implantation, and birth rates have been reported after the use of reduced O2 concentration during embryo culture, mainly due to a reduction of the cumulative detrimental effects of reactive oxygen species. However, some studies have failed to report any positive effects. The objective of this meta-analysis was to evaluate the effect of a low-O2 environment on IVF/intracytoplasmic sperm injection (ICSI) outcomes. METHODS: All available published and ongoing randomised trials that compared the effects of low (~5%; OC~5) and atmospheric (~20%; OC~20) oxygen concentrations on IVF/ICSI outcomes were included. Search strategies included online surveys of databases from 1980 to 2011. The outcomes measured were fertilisation rate, implantation rate and ongoing pregnancy rates. The fixed effects model was used to calculate the odds ratio. RESULTS: Seven studies were included in this analysis. The pooled fertilisation rate did not differ significantly (P=0.54) between the group of oocytes cultured at low O2 tension and the group at atmospheric O2 tension. Concerning all cycles, the implantation (P=0.06) and ongoing pregnancy (P=0.051) rates were not significantly different between the group receiving transferred sets containing only OC~5 embryos and the group receiving transferred sets with only OC~20 embryos. In a meta-analysis performed for only those trials in which embryos were transferred on day 2/3, implantation (P=0.63) and ongoing pregnancy (P=0.19) rates were not significantly different between the groups. In contrast, when a meta-analysis was performed using only trials in which embryos were transferred on days 5 and 6 (at the blastocyst stage), the group with transferred sets of only OC~5 embryos showed a statistically significantly higher implantation rate (P=0.006) than the group receiving transferred sets with only OC~20 embryos, although the ongoing pregnancy (P=0.19) rates were not significantly different between the groups. CONCLUSIONS: Despite some promising results, it seems too early to conclude that low O2 culture has an effect on IVF outcome. Additional randomised controlled trials are necessary before evidence-based recommendations can be provided. It should be emphasised that the present meta-analysis does not provide any evidence that low oxygen concentration is unnecessary.

Vertebroplastia percutânea: uma opção no tratamento de fraturas vertebrais em pacientes osteoporóticos / Percutaneous vertebroplasty: vertebral fractures treatment options in osteoporosis patients

Osteoporose é a primeira causa de fraturas com colapso do corpo vertebral, responsável por até 700 mil casos, com 150 mil internações por ano somente nos Estados Unidos. O quadro clínico é caracterizado por dor intensa, restrição à deambulação, baixa estima e depressão com limitação para as atividades diárias. Dentre as opções de tratamento destaca-se a vertebroplastia, uma técnica de acesso percutâneo ao corpo da vértebra no qual se injeta cimento acrílico. Este método é indicado no tratamento de fraturas vertebrais compressivas espontâneas secundárias à osteoporose ou a tumores vertebrais. Consiste em um procedimento cirúrgico minimamente invasivo, resultando na maioria dos casos em alívio imediato da dor e relativa estabilização vertebral
