Article Synopsis
- The review focuses on malignant germ cell neoplasms linked to gonadal dysgenesis, highlighting gonadoblastoma as the most common type, while discussing rare forms like dysgerminomas, yolk-sac tumors, and teratomas.
- A systematic review was conducted through PubMed and Medline, examining an extensive range of studies to gather high-quality data on the incidence of these tumors, with thousands of relevant papers identified over several decades.
- The review emphasizes the connection between chromosomal anomalies in gonadal dysgenesis and increased germ cell tumor incidence, suggesting that these anomalies may involve the Y chromosome or certain genes, contributing to the development of neoplasms.

Article Synopsis
- The review discusses the harmful effects of endocrine disrupting chemicals (EDCs) on the reproductive health of women and wildlife, highlighting their widespread use in agriculture and resulting environmental contamination.

Article Synopsis
- PCOS is a common endocrine disorder in women of childbearing age, with a significant number (28% to 46%) also experiencing metabolic syndrome, which is linked to non-alcoholic fatty liver disease (NAFLD).
- A study involving 131 women (101 with PCOS and 30 controls) aimed to determine the prevalence of NAFLD and metabolic syndrome in PCOS patients and explore any correlations between the two.
- Results showed that NAFLD was present in 23.8% of the PCOS group compared to 3.3% in controls, and metabolic syndrome was diagnosed in about one-third of the PCOS patients, indicating a notable association between PCOS and these metabolic conditions.
Fatigue and quality of life in breast cancer survivors: a comparative study.
Rev Bras Ginecol Obstet
March 2015
Purpose: To assess fatigue and quality of life in disease-free breast cancer survivors in relation to a sample of age-matched women with no cancer history and to explore the relationship between fatigue and quality of life.
Methods: A cross-sectional study was conducted in a sample of 202 consecutive disease-free Brazilian breast cancer survivors, all of whom had completed treatment, treated at 2 large hospitals. The patients were compared to age-matched women with no cancer history attending a primary health care center.
This paper aimed to report a series of 19 cases of uterus didelphys associated with obstructed hemivagina and ipsilateral renal agenesis. This retrospective descriptive observational study included the medical records of 19 patients seen at the Endocrinology Gynecology Sector of the Obstetrics and Gynecology Department of the Federal University of Paraná, and focused on clinical data, complementary exams, patient management, and follow-up. From the 229 patients with genital anomalies seen between 1984 and 2009, 19 (8.

Rev Bras Ginecol Obstet
October 2012
Purposes: To assess the quality of life of breast cancer survivors compared to a sample of age-matched healthy women.
Methods: A cross-sectional design was conducted on 199 consecutive breast cancer survivors, one year or more after diagnosis, treated at two large hospitals. The patients were compared to age-matched healthy women consisting of employees and volunteers of the two hospitals.
Fatigue after treatment in breast cancer survivors: prevalence, determinants and impact on health-related quality of life.
Support Care Cancer
August 2012
Purpose: Fatigue is a phenomenon that may persist for years after completion of adjuvant therapy, and is one of the most frequent symptoms associated with breast cancer survivors. The purposes of this study were to investigate the occurrence of fatigue in disease-free breast cancer survivors after treatment, to identify variables associated with fatigue, and to evaluate the impact of fatigue on health-related quality of life.
Methods: A cross-sectional study was conducted on 202 consecutive women diagnosed with in-situ to Stage III breast cancer attending in outpatient facilities of two large hospitals, one year or more after diagnosis.
There is little information about the knowledge and attitudes of physicians regarding oral care. This study aimed to assess the knowledge and attitudes of obstetricians about the relationship between periodontal disease and preterm/low birth weight. A questionnaire was emailed to members of the Brazilian Federation of Gynecology and Obstetrics (FEBRASGO).

Methods: this was a prospective cohort study of 90 pregnant patients between 6 and 8 weeks plus 6 days weeks of gestation. We included women at low risk, without acute or chronic systemic disease and with spontaneous conception.
Objective: Compare levels of androgens and bone mineral density (BMD) of ovariectomized (OVX) and non-ovariectomized (NOVX) postmenopausal women. Forty women, 20 OVX and 20 NOVX, (53.9 +/- 4 years) were selected.

- Successful liver transplantation can restore libido and fertility in women, but pregnancies after the procedure are considered high-risk due to increased complications.
- A 1978-2007 MEDLINE search explored the relationship between liver transplantation and pregnancy, concluding that there aren't formal guidelines but established "golden rules" can help improve outcomes.
- Recommended practices include delaying pregnancy for at least a year post-transplant, ensuring stable immunosupression, and involving a specialized obstetrics team to monitor maternal and fetal health effectively.
Article Synopsis
- The study aimed to investigate the link between human papillomavirus (HPV) and endometrial cancer by comparing data from women with endometrial carcinoma to those with normal tissue.
- A total of 100 women (50 with cancer and 50 without) were analyzed through HPV-DNA testing of tissue samples, considering factors like age, smoking, and tumor characteristics.
- Results showed no significant association between HPV presence and endometrial carcinoma, with HPV types 16 and 18 being the most common in both groups.
The present survey was conducted among medical students and physicians affiliated to the Federal University of Paraná, Curitiba, Brazil, between August 2006 and December 2007. 252 individuals responded to a questionnaire composed of 13 items regarding their individual status and their personal knowledge of the HPV vaccine properties. The data analysis that was carried out using chi-square test showed that 79.

Article Synopsis
- The study aimed to assess whether measurements of epiphyseal ossification centers can accurately estimate gestational age in fetuses.
- Women with singleton pregnancies between 30-40 weeks participated, and researchers measured the dimensions of specific ossification centers to create a nomogram for fetal bone development.
- Results showed a strong correlation between gestational age and the diameters of these centers, especially when combining measurements, suggesting that ultrasound imaging of ossification centers could serve as a reliable indicator of fetal age.
