RESUMO
OBJECTIVE: To evaluate the determinants of breast density in women with premature ovarian insufficiency (POI). METHODS: In a cross-sectional study of 163 women with POI undergoing mammography, percent mammographic density (PMD) was evaluated by digitizing the image. PMD was correlated with age, age at menarche, age at POI, time since POI, body mass index (BMI), gestational history and hormone therapy (HT) use (duration, dose, regimen). RESULTS: POI was diagnosed at a mean age of 32.3 ± 5.9 years. The mean age of the women at mammography was 41.3 ± 5.4 years; mean BMI was 27.4 ± 5.4 kg/m2 and mean PMD was 24.3 ± 18.5. Mean PMD did not differ between the different age groups evaluated (29-39, 40-49 and 50-55 years) or between users and non-users of HT. Mean duration of HT use was 5.6 ± 4.7 years. PMD was higher in nulligravidas compared to women who had been pregnant (p = 0.0016); however, POI occurred earlier in nulligravidas (p < 0.0001). PMD correlated negatively with BMI (r = -0.27; p = 0.0005). CONCLUSION: In women with POI, HT use had no effect on PMD, irrespective of the duration of use, dose or regimen. Pregnancy and BMI were consistently associated with PMD, with density being greater in nulligravidas and in women with lower BMI.

Premature ovarian insufficiency has the following causes: genetic, autoimmune, metabolic, infectious, and iatrogenic dysfunctions (including radiotherapy, chemotherapy and surgery). However, premature ovarian insufficiency remains without a definite cause in a substantial number of cases. This article describes GAPO syndrome in association with premature ovarian insufficiency, as well as a novel ANTXR1 gene mutation. Histopathological study of the ovaries of a woman with hypergonadotropic hypogonadism revealed extensive deposition of hyaline extracellular material, with bilateral parenchymal atrophy and follicular depletion. Molecular study revealed a novel ANTXR1 gene mutation. The homozygous c.378 + 3A > G transition at the consensus donor splice site of intron 4 was identified. Our results support the involvement of ANTRX1 gene mutations in deregulated extracellular matrix. In addition, our study identified a novel ANTXR1 mutation causing GAPO syndrome, indicating it as a new cause of early loss of ovarian function.

OBJECTIVE: To evaluate vaginal microbiological and functional aspects in women with and without premature ovarian failure (POF) and the relationship with sexual function. METHODS: A cross-sectional study of 36 women with POF under hormonal therapy who were age-matched with 36 women with normal gonadal function. The vaginal tropism was assessed through hormonal vaginal cytology, vaginal pH and vaginal health index (VHI). Vaginal flora were assessed by the amine test, bacterioscopy and culture for fungi. Sexual function was evaluated through the questionnaire Female Sexual Function Index (FSFI). RESULTS: Women in both groups were of similar age and showed similar marital status. The two groups presented vaginal tropic scores according to the VHI but the tropism was worse among women in the POF group. No difference was observed with respect to hormonal cytology and pH. Vaginal flora was similar in both groups. Women with POF showed worse sexual performance with more pain and poorer lubrication than women in the control group. The VHI, the only parameter evaluated showing statistical difference between the groups, did not correlate with the domains of pain and lubrication in the FSFI questionnaire. CONCLUSION: These findings suggest that the use of systemic estrogen among women with POF is not enough to improve complaints of lubrication and pain despite conferring similar tropism and vaginal flora. Other therapeutic options need to be evaluated.

BACKGROUND: Women with endometriosis may have higher rates of autoimmune disorders, including hypothyroidism. The objective of this study was to compare the prevalence of thyroid dysfunction and autoimmune thyroid disease (AITD) between women with endometriosis and a control group. METHODS: This was a cross-sectional study carried out in 148 women with surgically confirmed endometriosis and 158 controls. The mean age of the study group was 34.6 (7.1 SD) years (range 21-42) and 32.1 (7.7 SD) years (range 18-44) for controls. Serum levels of thyroid-stimulating hormone, free thyroxine and the anti-thyroperoxidase and anti-thyroglobulin antibodies were evaluated. RESULTS: Thyroid disorders were identified in 20.9% of the endometriosis group and 26.5% of the control group (P = 0.25). The overall frequency of thyroid dysfunction was 12.2% and 10.8% for the endometriosis and control groups, and the frequency of positive thyroid antibodies, 14.9% and 22.2%, respectively (P = 0.20). Endometriosis stage and infertility history were not associated with thyroid dysfunction and AITD in the study group. CONCLUSIONS: The prevalence of thyroid dysfunction and AITD was similar in the two study groups. Screening for thyroid disturbances in women with endometriosis is not indicated.

BACKGROUND: The study aim was to assess the time elapsed between onset of symptoms and diagnosis of endometriosis, and to identify the factors associated with diagnostic delay in a group of Brazilian women. METHODS: In this retrospective cohort study, 200 women with surgically confirmed endometriosis were interviewed at an endometriosis outpatient clinic. RESULTS: The median (interquartile range) time elapsed from onset of symptoms until diagnosis of endometriosis was 7.0 (range 3.5-12.1) years. The younger the women at onset of symptoms, the longer the period for diagnosis to be made: the median delay was 12.1 (range 8.0-17.2) years in women aged < or =19 years, and 3.3 (range 2.0-5.5) years in women aged > or =30 years. The median time period between onset of symptoms and diagnosis was 4.0 (2.0-6.0) years for women whose main complaint was infertility, but 7.4 (3.6-13.0) years for those with pelvic pain. CONCLUSIONS: The delay in diagnosis of endometriosis was considered to be long, and especially so for young women with pelvic pain. More information relating to endometriosis should be offered to general physicians and gynaecologists in order to reduce the time taken to diagnose this condition.
