RESUMO

Objective: This study aimed to evaluate the effect of laparoscopic cystectomy on ovarian reserve in patients with ovarian cysts. Material and methods: This prospective study was performed on 113 women with ovarian cysts in a tertiary referral teaching hospital. All patients underwent laparoscopic cystectomy. Serum levels of antimüllerian hormone (AMH) were measured pre-and, 3 months postoperatively. The primary outcome of the study was to assess the effect of laparoscopic cystectomy on ovarian reserve based on alterations in serum AMH levels. The secondary outcome of the present study was to evaluate the impact of the number of cauterizations, size and type of cysts, bilaterality (bilateral or unilateral), age, and body mass index (BMI) on the ovarian reserve after laparoscopic excision. Results: Laparoscopic cystectomy reduced the serum AMH levels preoperatively (1.32 ± 4.48 ng/ml) to postoperatively (3.2 ± 1.93 ng/ml) and the difference (- 1.28 ng/ml) was statistically different (0.001 >P). There was a negative significant relationship between the number of cauterizations used and postoperative serum AMH levels (p ≤ 0.001). There was a significant relationship between the location (p ≤ 0.01), type of cyst (p ≤ 0.001) and the serum AMH levels reduction. Conclusion: The number of cauterizations used during surgery, the type of cyst, and bilaterality can affect AMH levels that need to be addressed.

RESUMO

The purpose of this study was to compare the surgical outcomes and efficacy of 3-dimensional (3D) versus 2-dimensional (2D) imaging systems for the treatment of ovarian cyst. A total of 46 patients undergoing a laparoscopic ovarian cystectomy were randomly assigned to either the 3D or 2D laparoscopy group. The primary outcome measure was the operative blood loss. The secondary outcome measure was visually induced motion sickness (VIMS), task efficacy during laparoscopy, and postoperative complication. There were no differences in baseline demographics between the two groups. The operative blood loss was significantly smaller in the 3D groups (28.7 ± 11.6 mL) than in the 2D groups (46.5 ± 24.4 mL) (p = .012). VIMS score was significantly higher in the 3D groups than the 2D groups (p < .001). 3D laparoscopy was superior to 2D in terms of the task efficacy of ovarian cyst enucleation (p < .001), adhesiolysis or dissection (p < .001), and ovarian suturing (p = .008). None of the patients in both groups developed operative complications. In conclusion, a 3D imaging system showed a more favourable surgical outcome and improved task efficacy than 2D in laparoscopic ovarian cystectomy. However, 3D laparoscopy tends to cause more frequent VIMS in surgeons.Impact statementWhat is already known on this subject? Several studies examining the possible benefits and drawbacks of a 3D imaging system versus 2D in laparoscopic surgery have brought about conflicting results. However, there have been few studies comparing the surgical outcomes of 3D and 2D laparoscopic ovarian cystectomy.What do the results of this study add? 3D laparoscopy showed favourable surgical outcomes and improved task efficacy than 2D laparoscopy in ovarian cystectomy.What are the implications of these findings for clinical practice and/or further research? More complex procedures, such as suturing and adhesiolysis, might be easier to perform with 3D laparoscopy than with 2D laparoscopy. Therefore, further large studies of 3D gynaecologic laparoscopy with different complexities and for surgeons with different surgical skills are needed.

RESUMO

The common gynaecological causes of acute pelvic pain include ruptured ectopic pregnancy, haemorrhagic corpus luteal cyst or torsion of an ovarian cyst. Ovarian vascular accidents are reported in women on oral anticoagulation presenting as an acute pelvic pain. Although such vascular accidents with anticoagulation therapy are an unusual entity, a meticulous history, clinical examination, and laboratory workup to confirm the diagnosis and timely intervention is needed to reduce attending morbidity and mortality. However, a standard algorithm for management is not described in the literature. We hereby report successful management of recurrent hemorrhagic ovarian cyst due to coagulopathy in a woman with mechanical heart valves with timely surgical intervention. This case report discusses operative versus non operative management approach and may provide value addition to readers encountering such cases in their clinical practice.

RESUMO

Primary hypothyroidism can lead to delayed growth and pseudoprecocious puberty in juvenile patients, which was known as Van Wyk-Grumbach's syndrome (VWGS). There have been very few clinical case reports of primary juvenile hypothyroidism presenting with concurrent huge bilateral cystic ovaries. Here, we report the case of a 14-year-old female patient suffering from primary hypothyroidism in combination with bilateral cystic ovaries. Remarkable improvement of symptoms was observed after one month of hormone replacement therapy and an unnecessary surgical treatment was avoided. A comprehensive literature review of VWGS is summarised here to illustrate the presentation, diagnosis, and treatment of VWGS in pediatric patients. The present study aims to improve the current clinical knowledge of VWGS.

RESUMO

Ovarian cysts are one of the most common ovarian dysfunctions in dairy cattle, which can lead to a considerable economic loss through its high incidence and can reduce the reproductive performance. Anestrus is the most significant clinical sign observed in dairy cattle suffering from this condition. For diagnosis, most of the veterinarians use a combination of methods, from ultrasonography as an additional approach to trans-rectal palpation and symptomatology when assessing ovarian cysts. Although the Ovsynch treatment seems to be preferred, the pregnancy rate after this treatment is relatively low. Despite such reports on dairy cattle ovarian cysts, the data is insufficient to validate all the characteristics of this condition. This review summarizes what the literature has so far provided from definition to treatment of ovarian cysts in dairy cattle.

RESUMO

Endometriosis is a benign gynaecological disease appearing with pelvic pain, rising dysmenorrhoea and infertility seriously impacting on 10% of reproductive-age females. This research attempts to demonstrate the function and molecular mechanism of RhoA/ROCK pathway on epithelial-mesenchymal transition (EMT) and proliferation in endometriosis. The expression of Rho family was abnormally changed in endometriotic lesions; in particular, RhoA and ROCK1/2 were significantly elevated. Overexpression of RhoA in human eutopic endometrial epithelial cells (eutopic EECs) enhanced the cell mobility, epithelial-mesenchymal transition (EMT) and proliferation, and RhoA knockdown exhibited the opposite function. Oestrogen up-regulated the RhoA activity and expression of RhoA and ROCK1/2. RhoA overexpression reinforced the effect of oestrogen on promoting EMT and proliferation, and RhoA knockdown impaired the effect of oestrogen. oestrogen receptor α (ERα) was involved with the regulation of oestrogen on EMT and proliferation and up-regulated RhoA activity and expression of RhoA and ROCK1/2. The function of ERα was modulated by the change in RhoA expression. Furthermore, phosphorylated ERK that was enhanced by oestrogen and ERα promoted the protein expression of RhoA/ROCK pathway. Endometriosis mouse model revealed that oestrogen enhanced the size and weight of endometriotic lesions. The expression of RhoA and phosphorylated ERK in mouse endometriotic lesions was significantly elevated by oestrogen. We conclude that abnormal activated RhoA/ROCK pathway in endometriosis is responsible for the function of oestrogen/ERα/ERK signalling, which promoted EMT and proliferation and resulted in the development of endometriosis.

RESUMO

OBJECTIVE: To assess ovarian reserve through antral follicle count (AFC) and ovarian volume (OV) determination after decapsulation (stripping technique) or CO2 laser vaporization in the surgical treatment of patients with bilateral ovarian endometriomas. METHODS: This prospective, randomized, blinded, self-controlled pilot study was set in a tertiary university hospital between January 2017 and December 2017, and included consecutive patients with bilateral ovarian endometriomas ≥3 cm. The study was registered with ClinicalTrials.gov under the title 'Impact on ovarian reserve according to the type of ovarian endometrioma excision: laser versus conventional cystectomy'; NCT03826355. For each patient, the endometrioma on one side was randomly selected to undergo CO2 laser vaporization and the contralateral endometrioma to undergo laparoscopic decapsulation. RESULTS: A total of 16 patients were included. There were no statistically significant between-group differences in OV and AFC levels at baseline. At the 6-month follow-up, OV and AFC levels were significantly higher in the laser-treated group versus the stripping technique. CONCLUSION: Lower OV and AFC levels following excisional surgery for endometrioma versus CO2 laser vaporization suggest a higher impact on ovarian reserve after the stripping procedure.

RESUMO

BACKGROUND AND AIM: While the relationship between obesity and reproductive dysfunction is well known, the physiological mechanism behind obesity-related infertility remains unclear. Previous work suggests that follicle development prior to ovulation is disrupted in obese individuals. Follicle-stimulating hormone (FSH) and anti-Mullerian hormone (AMH) are two key regulators of follicle development, and the poorest reproductive outcomes have been recorded when these hormones are imbalanced. In order to understand how obesity impacts the reproductive axis, the present study induces reproductive dysfunction in female rats using a high-fat, high-sugar diet (HFHS). Results: In our study, several animals on the HFHS diet displayed abnormal estrous cycles. The HFHS diet also resulted in an increased prevalence of ovarian cysts and decreased formation of corpora lutea. Across all groups, the FSH/AMH ratio displayed a strong negative correlation with pre-antral, antral, and total follicle counts. Moreover, rats on the HFHS diet displayed larger adipocytes and produced higher levels of leptin than controls. When combined with average adipocyte size in multiple regression, the FSH/AMH ratio was strongly associated with cyst formation in the ovary. Conclusions: These findings provide strong evidence for the potential relevance of a combined FSH/AMH ratio as a marker of ovarian health and follicular status. Therefore, this ratio reflects a complex interaction between the reproductive and metabolic systems.

RESUMO

The objective of this study was to identify proteins that are differentially expressed in the cystic wall tissues of ovarian endometriotic cysts, simple ovarian cysts, and in normal ovarian tissues. Specimens of ovarian endometriotic cyst wall tissue, simple ovarian cyst wall tissue, and normal ovarian tissue (six specimens per group) were collected from patients who received gynecologic surgery, respectively. Differentially expressed proteins related to the ovarian endometriotic cysts were screened by use of isobaric tags for relative and absolute quantitation (iTRAQ) combined with functional annotation and bioinformatics analyses. All differentially expressed proteins related to cysts were validated using immunohistochemistry methods in recurrent and non-recurrent ovarian endometriotic cyst. A total of 359 proteins were identified as up-regulated in ovarian endometriotic cyst groups when compared with both the normal ovary and simple ovarian cyst groups. The levels of 27 proteins were >two-fold higher in the ovarian endometriotic cyst group than that in the other two groups. Of note, the five most significantly upregulated proteins were Charcot-Leyden Crystal Galectin (CLC), Defensin, alpha 1 (DEFA1), S100 calcium-binding protein A9 (S100A9), S100 calcium-binding protein A8 (S100A8), and Ferritin Light Chain (FTL). Immunohistochemistry results showed that the changes of S100A9 and S100A8 were consistent with the results shown by iTRAQ. However, no similarity of CLC, DEFA1, and FTL proteins was found between iTRAQ and immunohistochemistry. The ratio of patients with abnormally high S100A9 and S100A8 expression in the recurrent ovarian endometriotic cyst group was significantly higher than that in the non-recurrent group (P < 0.05). Our data identify differentially expressed proteins S100A9 and S100A8, and suggest they may serve as novel molecular markers to predict postoperative recurrence of an ovarian endometriotic cysts.Abbreviations: iTRAQ: isobaric tags for relative and absolute quantitation; HPRD: Human Protein Reference Database; GO: Gene Ontology; KEGG: Kyoto Encyclopedia of Genes and Genomes; EM: Endometriosis; COX-2: cyclooxyenase-2; NF-kB: nuclear factor kappa-B; PR-B: progesterone receptor type B.

RESUMO

AIM: We evaluated and compared the clinical and pathological differences between pregnant and non-pregnant women with adnexal torsion. METHODS: We retrospectively reviewed 239 women with adnexal torsion from January 2006 to December 2015 in a tertiary hospital. The clinical and pathological differences between pregnant and non-pregnant women who underwent surgery for adnexal torsion were analyzed. RESULTS: The most common pathologies were corpus luteum cysts in pregnant women and dermoid cysts in non-pregnant women. Eight of the pregnant women (24.2%) had a history of exogenous ovarian stimulation, and their episodes were only caused by corpus luteum or a stimulated ovary. In pregnant women, 72.7% of the torsion occurred before the 14th week of gestation. CONCLUSION: The common pathology causing adnexal torsion was different, depending on the pregnancy status. Exogenous ovarian stimulation increases the risk of adnexal torsion, and the majority of episodes occurred in the first trimester in pregnant women.

RESUMO

A 34-year-old woman presented our hospital with complaint of irregular menstruation and abnormal uterine bleeding lasting for a month. After her second parturition at the age of 27, her menstrual cycle had been regular, but it suddenly became irregular at the age of 30. Transvaginal ultrasound revealed the presence of ovarian mass, and the patient underwent diagnostic laparoscopic surgery. Bilateral ovaries temporally shrink after puncture but the size soon resumed. Gonadotropins were almost normal, but estradiol and PRL levels turned out to be elevated, and cabergoline treatment was initiated. After referral to our hospital, we found that the ovaries showed multifollicular appearance. Brain magnetic resonance imaging showed an 18-mm macroadenoma in the suprasellar area. To suppress the secretion of endogenous gonadotropins and estrogen, low-dose estrogen-progestin was prescribed. Surprisingly, the treatment temporarily reduced the size of the ovaries. The patient was referred to a neurosurgeon, and a functioning gonadotroph adenoma was suspected. After the resection of the pituitary tumor, her menstrual cycle became regular, and the size of bilateral ovaries became normal. We also noticed that her ovarian reserve judged by anti-Müllerian hormone had been almost diminished after the surgical treatment, probably reflecting the exhaustion of follicular pool. Women with multifollicular ovaries and elevated estradiol levels may have functioning gonadotroph adenomas, although the level of FSH is relatively normal, and ovarian reserve can be followed by measuring anti-Müllerian hormone.

RESUMO

Spontaneous hyperstimulation syndrome (spOHSS) is a rare event in pregnancies following natural conception. Only a few cases are reported in the scientific literature and result associated with massive ovarian enlargement with multiple cysts, dehydration, and fluid accumulation in the "third space". We report a novel case of spOHSS in a naturally conceived singleton pregnancy. The spOHSS was characterized by massive ovarian enlargement with multiple cysts. No dehydration and no signs of ascites were observed. The pregnancy uneventful evolved up to term.

RESUMO

OBJECTIVE: Residual ovarian syndrome (ROS) occurs after a hysterectomy in which one or both ovaries have been preserved and cause chronic pelvic pain, an asymptomatic pelvic mass, or dyspareunia. We present a case with classic symptoms and imaging and pathology findings, and review the treatment of residual ovarian syndrome. CASE REPORT: A 35-year-old woman with a diagnosis of ROS. CONCLUSION: Based on previous literature, almost 50% of patients with ROS require surgery for their symptoms. Treatment of ROS with gonadotropin-releasing hormone analogs or high dose progestogens may be helpful. However, there are limited data supporting the efficacy of pharmacologic therapy. Patients receiving pharmacologic therapy should be counseled about the limited data supporting the efficacy of this approach, the lack of a histologic diagnosis, and the risk of ovarian cancer in residual tissue.

RESUMO

The new paradigm of mutations in chromatin-modifying genes as driver events in the development of cancers has proved challenging to resolve the complex influences over disease phenotypes. In particular, impaired activities of members of the SWI/SNF chromatin remodeling complex have appeared in an increasing variety of tumors. Mutations in SNF5, a member of this ubiquitously expressed complex, arise in almost all cases of malignant rhabdoid tumor in the absence of additional genetic alterations. Therefore, we studied how activation of additional oncogenic pathways might shift the phenotype of disease driven by SNF5 loss. With the use of a genetically engineered mouse model, we examined the effects of a hypomorphic Vhl2B allele on disease phenotype, with a modest up-regulation of the hypoxia response pathway. Snf5+/-;Vhl2B/+ mice did not demonstrate a substantial difference in overall survival or a change in malignant rhabdoid tumor development. However, a high percentage of female mice showed complex hemorrhagic ovarian cysts, a phenotype rarely found in either parental mouse strain. These lesions also showed mosaic expression of SNF5 by immunohistochemistry. Therefore, our studies implicate that modest changes in angiogenic regulation interact with perturbations of SWI/SNF complex activity to modulate disease phenotypes.

RESUMO

This study aimed to clarify the relationship between functional ovarian cysts and vitamin A, vitamin E, and folate intake. This case-control study evaluated 265 women of reproductive age who presented at gynaecology clinics of three hospitals in Mashhad, Iran. While women in the ovarian cyst group [n = 132] had functional ovarian cysts, control group [n = 133] consisted of women without functional ovarian cysts. The participants' vitamin A, vitamin E, and folate intake was assessed using the Food Frequency Questionnaire. Results showed that folate intake was significantly higher in the ovarian cyst group [p = .040]. No significant differences in vitamin A and vitamin E intake were observed between the two groups [p = .950 and .230, respectively]. It is concluded that women with functional ovarian cysts had significantly higher folate intake. Vitamin A and vitamin E intake had no significant effects on the incidence of these cysts.

RESUMO

OBJECTIVE: To evaluate the effect on ovarian reserve and blood flow of unilateral laparoscopic stripping of endometriotic versus non-endometriotic cysts. DESIGN: Prospective observational study. SETTING: Tertiary university gynecology unit. PATIENTS: During the study period, 71 subjects underwent the first laparoscopic surgery for removal of a monolateral benign ovarian cyst. INTERVENTIONS: Trans-vaginal ultrasound scans of the pelvis about six months after surgery. MAIN OUTCOME MEASURES: Ovarian volume, Antral Follicle Count (AFC) and Resistance Index (RI) of ovarian artery of the operated and the contralateral ovary. RESULTS: Among 71 cysts, 39.4% were endometriotic and 60.6% non-endometriotic benign cysts. All the procedures were performed by the same experienced surgeons with a standardized technique. No major complications were reported during surgery. The mean (±SD) age and BMI of women were 31.0 ± 6.8 years and 24.2 ± 3.3 kg/m(2), respectively. Mean diameter of the removed cysts was smaller for endometriotic than non-endometriotic cysts (4.35 ± 1.77 cm versus 6.33 ± 3.71 cm, p = 0.046). In comparison to non-operated, volume of the operated ovary was significantly lower and with a reduced AFC, with no difference between endometriotic and non-endometriotic cysts (-2.41 ± 2.35 versus -2.00 ± 2.23 cm(3), p = 0.496) (-3.45 ± 3.07 versus -2.43 ± 1.95, p = 0.11). Ovarian artery RI was higher in the operated ovary with no difference between endometriotic and non-endometriotic cysts (0.19 ± 0.14 versus 0.14 ± 0.10, p = 0.455). The difference in ovarian volume (r = 0.178), AFC (r = 0.094) and RI (r = 0.079) between operated and non-operated ovary was not dependent on the diameter of the removed cyst. CONCLUSION: Ovarian surgery is associated with a decline of ovarian reserve, independently on the histological type and the diameter of the removed cyst.

RESUMO

Van Wyk-Grumbach syndrome (VWGS) is a rare complication of prolonged untreated juvenile hypothyroidism characterized by precocious puberty and enlarged multicystic ovaries. A 13-year-old girl visited our outpatient clinic due to menstrual irregularities. She had precocious puberty, pituitary hyperplasia and multiple cystic ovaries in addition to clinical signs of severe congenital hypothyroidism. After the initiation of L-thyroxine therapy, the symptoms were alleviated in a short time. This rare syndrome is easy to be misdiagnosed as pituitary and ovarian tumor.
