When an inguinal hernia is more than just a hernia with ovary and fallopian tube involvement: a case report.

BACKGROUND: Finding an ovary and/or fallopian tube within an indirect inguinal hernia is a rare occurrence that can be detected incidentally during elective surgery or present as a medical emergency requiring immediate intervention. Hence, it poses a difficult clinical picture in a reproductive-age woman with groin mass. CLINICAL PRESENTATION: We describe the case of a 45-year-old Ethiopian woman of Amhara ethnicity who presented with a left inguinal swelling that persisted for 5 years. Physical examination revealed an irreducible, non-tender lump in the left groin and an ultrasonography scan confirmed the presence of an indirect inguinal hernia. The patient was then scheduled for elective hernia repair. During the surgery, both her left ovary and fallopian tube were found within the hernial sac. The contents were released from the sac, high ligation performed, and the inguinal floor repaired with mesh. DISCUSSION: Inguinal hernias in women are rare and often present a diagnostic challenge. Although the exact pathogenesis of inguinal hernias containing female genital organs is unknown, some risk factors have been postulated. Diagnosis should start with a physical exam and imaging, but many of the cases have been intraoperative surprises. Management is primarily surgical, ranging from simple reduction and hernia repair to salpingo-oophorectomy depending on the status of the hernia contents. CONCLUSION: This report emphasizes the importance of maintaining a high index of suspicion when examining females with inguinal hernias to ensure accurate diagnosis and management of tubo-ovarian hernias. Although rare, inguinal hernias containing female genital organs should be considered in the differential diagnosis of inguinal hernias, as early detection and appropriate surgical management can prevent potential complications.

Anastomosing hemangioma of the ovary - a comprehensive review of this rare ovarian entity.

BACKGROUND: Anastomosing hemangioma of the ovary is a rare vascular tumor that predominantly affects middle-aged women. Despite its benign nature, its histological appearance can mimic aggressive vascular lesions, posing diagnostic challenges. This review aims to provide an overview of this uncommon entity. METHODS: The PubMed and Scopus databases were searched for relevant articles published in English. Information on all retrieved cases was extracted and reviewed in detail. RESULTS: We found 33 cases with relevant details of anastomosing heamangioma of the ovary. Despite the small number of cases we found, our study demonstrated the importance of an accurate hystopathological evaluation. CONCLUSIONS: Although the preliminary imaging and initial microscopic features may appear alarming, careful microscopic examination reveals benign behavior. There is a need to raise awareness of this unusual and rare entity to improve morphologic recognition and avoid misdiagnosis that could lead to unnecessary treatment or patient anxiety.

Diagnosis of a large cystic teratoma of accessory ovary complicated with torsion by ultrasound: A case report.

RATIONALE: An accessory ovary complicated by cystic teratoma and torsion is extremely rare and requires prompt diagnosis and surgical treatment. However, evidence for effective preoperative imaging diagnosis has barely been reported. Our study presented a case in which preoperative ultrasound reasonably suspected ovarian tumor torsion and an accessory ovary, and laparoscopic surgery was strategically performed. PATIENT CONCERNS: An 18-year-old girl had persistent pain in the lower right abdomen for over 7 hours accompanied by nausea and vomiting, and she had a 14.1 × 10.1 × 9.0 cm hypo-echoic cystic lesion containing a 6.4 × 4.9 × 3.0 cm solid component accompanied by the whirlpool sign on the right side of the pelvis. Additionally, a hyper-echoic ovary with a size of 2.5 × 1.4 cm and a normal ovary appearance of 2.4 × 0.8 cm were detected on the right side of the adnexal area by ultrasound. DIAGNOSIS: The cystic lesion was a large accessory ovarian cystic teratoma, complicated by torsion. The hyperechoic ovary appears as accessory ovarian stromal edema and the normal ovary appearance is eutopic. INTERVENTIONS: Single-port laparoscopic resection of the ovarian lesion, release of the ovarian torsion, and oophoroplasty were performed. OUTCOMES: Postoperative recovery was unremarkable. Antral follicles were detected in both eutopic and accessory ovaries by ultrasound 20 days and 4 months after surgery. In addition, during the second postoperative ultrasound follow-up, the accessory ovary showed no difference in echo compared to the normal ovary, except for a slightly larger volume. LESSONS: Clinical manifestations of accessory ovarian tumors combined with torsion are similar to those of eutopic ovarian torsion, and timely surgery is required.

Mechanism of Zuogui pill enhancing ovarian function and skin elastic repair in premature aging rats based on artificial intelligence medical image analysis.

BACKGROUND: AI medical image analysis shows potential applications in research on premature aging and skin. The purpose of this study was to explore the mechanism of the Zuogui pill based on artificial intelligence medical image analysis on ovarian function enhancement and skin elasticity repair in rats with premature aging. MATERIALS AND METHODS: The premature aging rat model was established by using an experimental animal model. Then Zuogui pills were injected into the rats with premature aging, and the images were detected by an optical microscope. Then, through the analysis of artificial intelligence medical images, the image data is analyzed to evaluate the indicators of ovarian function. RESULTS: Through optical microscope image detection, we observed that the Zuogui pill played an active role in repairing ovarian tissue structure and increasing the number of follicles in mice, and Zuogui pill also significantly increased the level of progesterone in the blood of mice. CONCLUSION: Most of the ZGP-induced outcomes are significantly dose-dependent.

UNILATERAL OVARIAN TORSION IN FIVE GECKOS: CLINICAL AND ULTRASOUND FINDINGS.

Few cases of antemortem ovarian torsion and diagnosis have been described in reptiles. This case series reports clinical and ultrasound findings in five adult (aged 1-6 yr) female geckos (three leopard geckos [Eublepharis macularius], one crested gecko [Correlophus ciliatus], and one gargoyle gecko [Rhacodactylus auriculatus]) diagnosed with unilateral ovarian torsion between 2019 and 2023. All animals presented with acute weakness associated with coelomic distension, and one suffered from chronic diarrhea and cachexia. Coelomic ultrasound examination (12-MHz linear probe) revealed signs of bilateral follicular stasis and oophoritis in all cases (heterogenic follicles ≤1.3 cm diameter) associated with a large anechoic periovarian rim and a hyperechoic chord, consistent with twisted ovarian vessels. Blood supply to ovarian structures was not detected using a Doppler flow, and a unilateral ovarian torsion was diagnosed in all geckos. A bilateral ovariectomy was performed under general anesthesia in all five animals. The mass of the excised ovaries varied between 7 to 15 g (12.7-22.2% of body weight). One gecko died 1 d postsurgery; the four remaining animals were healthy 6 mon postsurgery. Gekkonids are unique among reptiles in that they undergo a monoautochronic ovulation (only one follicle is recruited by each ovary during each ovarian cycle); the presence of multiple vitellogenic follicles on each ovary facilitates the diagnosis of follicular stasis. This condition was present in all five geckos and was suspected to have led to ovarian torsion. This case series emphasizes the value of ultrasound examination for antemortem diagnosis of reproductive disorders in reptiles.

Clinical, radiological, and pathological features of mitotically active cellular fibroma of ovary: A review of cases with literature review.

OBJECTIVE: Mitotically active cellular fibroma (MACF) of the ovary, characterized by relatively high mitotic activity without severe atypia, was first described in the WHO classification in 2014. However, due to its rarity, the clinicopathological characteristics of ovarian MACF have not been established. This study was performed to describe the clinical, radiological, and pathological features of MACF by analyzing 11 cases of ovarian MACF. MATERIALS AND METHODS: Between 2015 and 2022, 11 patients with ovarian MACFs underwent surgical treatment at our institution. Clinicopathologic data of the patients were retrospectively reviewed from their medical records. RESULTS: Median patient age was 53.7 years (range 21-77 years), and median tumor diameter was 7.8 cm (range 4.3-14.0 cm). Preoperative CA125 was elevated in 4 cases. Four of the eleven patients had abdominal pain, and two presented with vulvar pain or a palpable abdominal mass, respectively. Preoperative radiological impressions included fibroma, fibrothecoma, stromal tumor, and cystadenocarcinoma. A laparoscopic approach was adopted in 7 cases (64%). Intraoperative frozen section was performed in 5 patients, and all demonstrated the presence of a benign, fibromatous stromal tumor. Three patients underwent fertility-sparing surgery, including laparoscopic ovarian cystectomy and unilateral salpingo-oophorectomy. Median follow-up was 37.7 months (range 2-84 months), and no patient experienced disease relapse or died of their disease. CONCLUSION: This study shows that ovarian MACF has a benign clinical course. Fertility-sparing surgery provides a safe therapeutic option for MACF, which can be managed safely by laparoscopy. Imaging findings and final pathological diagnosis were not well matched. Intraoperative frozen section is important for determining surgical extent in mitotically active cellular fibroma of the ovary.

The annual ovarian cycle in Northern pit vipers (Bothrops atrox) using serum steroids and ultrasound of the female reproductive tract.

Knowledge on hormonal regulation of reproductive cycles in viperid snakes is still incipient, especially when it comes to females and tropical species. There is an urgent need to understand the reproduction of venomous snakes to improve assisted reproduction techniques and optimize the maintenance of these animals in captivity. With this in mind, we monitored Northern pit viper females year-round throughout different seasons via serum levels of progesterone (P4) and estradiol (E2) in conjunction with ultrasound examinations. Ovarian follicles were classified according to their size and stage of vitellogenesis in F-I and F-II (non-vitellogenic phase) or in F-III and F-IV (vitellogenic phase). During autumn and winter, five adult males were rotated among these females for reproductive pairing, which resulted in 17 copulations and 2 pregnancies in the first year and 12 copulations and 5 pregnancies in the second year. Then, we assessed changes in P4 and E2 levels according to seasons, predominant ovarian structures and the presence of embryos or eggs in the oviduct. Our findings showed high levels of E2 when a greater number of vitellogenic follicles were detected, indicating a possible influence of E2 on vitellogenesis and higher levels of P4 whenever eggs and embryos were visualized in the oviduct, implying its role in maintaining pregnancy. Descriptive analysis of the vipers' ovarian cycles revealed a greater number of vitellogenic follicles during winter, probably as a result of increases in E2; whereas pregnancies occurred predominantly in spring, under the influence of P4. The use of ultrasound images, as a minimally invasive methodology, associated with serum steroid levels has proven to be an efficient approach in the reproductive monitoring of Northern pit vipers in vivo. In addition, these data suggest that female pit vipers under human care display a seasonal reproductive cycle, despite earlier studies involving captive males of the species indicating a lack of seasonality in sperm production and quality.

Nonvisualized Ovaries on Ultrasound: Correlation With Surgical Pathology.

ABSTRACT: The risk of malignancy in nonvisualized ovaries on pelvic ultrasound is presumed to be close to zero per imaging correlation; the goal of this manuscript is to define the risk of malignancy in nonvisualized ovaries on pelvic ultrasound as defined by surgical pathology. Records for patients with pelvic ultrasound and surgical pathology containing the word "ovary" or "ovaries" performed at our institution between 10/1/2015 and 9/30/2021 were reviewed. Data for ovarian visualization were extracted from the radiology report and correlated with surgical pathology results within each ovary. Eighty-seven ovaries in 71 patients out of 422 ovaries (20.6%) in 215 eligible patients were not visualized on ultrasound. Twenty ovaries were excluded because imaging showed large pelvic mass, and 19 ovaries were excluded because surgical pathology for the ovary of interest was not available. A total of 48 ovaries in 37 patients were nonvisualized and had available surgical pathology. Out of 48 nonvisualized ovaries, 31 were normal on surgical pathology and 17 had abnormalities, with 15 benign lesions (12 of which were ≤1 cm in size). Two ovaries in 1 patient contained malignant lesions; although the ovaries were not visualized on ultrasound, the scan demonstrated peritoneal carcinomatosis. In conclusion, a high proportion of ovaries (20.6%, 87/422) are not visualized on pelvic ultrasound, and surgical pathology reveals ovarian lesions in 35.4% (17/48) of nonvisualized ovaries on pelvic ultrasound, with the majority being subcentimeter benign lesions. In the absence of peritoneal carcinomatosis, nonvisualized ovaries had no malignant lesions.

Performance of O-RADS MRI Score in Differentiating Benign From Malignant Ovarian Teratomas: MR Feature Analysis for Differentiating O-RADS 4 From O-RADS 2.

OBJECTIVE: The aim of the study is to evaluate the performance of the ovarian-adnexal reporting and data system magnetic resonance imaging (O-RADS MRI) score and perform individual MRI feature analysis for differentiating between benign and malignant ovarian teratomas. METHODS: In this institutional review board-approved retrospective study, consecutive patients with a pathology-proven fat-containing ovarian mass imaged with contrast-enhanced MRI (1.5T or 3T) from 2013 to 2022 were included. Two blinded radiologists independently evaluated masses per the O-RADS MRI lexicon, including having a "characteristic" or "large" Rokitansky nodule (RN). Additional features analyzed included the following: nodule size/percentage volume relative to total teratoma volume, presence of bulk/intravoxel fat in the nodule, diffusion restriction in the nodule, angular interface, nodule extension through the teratoma border, presence/type of nodule enhancement pattern (solid versus peripheral), and evidence for metastatic disease. An overall O-RADS MRI score was assigned. Patient and lesion features associated with malignancy were evaluated and used to create a malignant teratoma score. χ 2 , Fisher's exact tests, receiver operating characteristic curve, and κ analysis was performed. RESULTS: One hundred thirty-seven women (median age 34, range 9-84 years) with 123 benign and 14 malignant lesions were included. Mean teratoma size was 7.3 cm (malignant: 14.4 cm, benign: 6.5 cm). 18/123 (14.6%) of benign teratomas were assigned an O-RADS 4 based on the presence of a "large" (11/18) or "noncharacteristic" (12/18) RN. 12/14 malignant nodules occupied >25% of the total teratoma volume ( P = 0.09). Features associated with malignancy included the following: age <18 years, an enhancing noncharacteristic RN, teratoma size >12 cm, irregular cystic border, and extralesional extension; these were incorporated into a malignant teratoma score, with a score of 2 or more associated with area under the curve of 0.991 for reviewer 1 and 0.993 for reviewer 2. Peripheral enhancement in a RN was never seen with malignancy (64/123 benign, 0/14 malignant) and would have appropriated downgraded 9/18 overcalled O-RADS 4 benign teratomas. CONCLUSIONS: O-RADS MRI overcalled 15% (18/123) benign teratomas as O-RADS 4 but correctly captured all malignant teratomas. We propose defining a "characteristic" RN as an intravoxel or bulk fat-containing nodule. Observation of a peripheral rim of enhancement in a noncharacteristic RN allowed more accurate prediction of benignity and should be added to the MRI lexicon for improved O-RADS performance.

Prediction of postoperative residual primary ovarian neoplasm or metastatic lesion close to rectum of serous ovarian carcinoma based on clinical and MR T1-DEI features.

BACKGROUND: The optimal primary debulking surgery outcome of serous ovarian carcinoma (SOC) is greatly affected by primary ovarian neoplasm or metastatic lesion close to the rectum. PURPOSE: To study the risk factors affecting postoperative residual primary ovarian neoplasm or metastatic lesion close to the rectum of SOC. MATERIAL AND METHODS: The clinical and MRI data of 164 patients with SOC eligible from institution A (training and test groups) and 36 patients with SOC eligible from institution B (external validation group) were collected and retrospectively analyzed. The clinical data included age, serum carbohydrate antigen 125 (CA-125), human epididymis protein 4, and neutrophil-to-lymphocyte ratio (NLR). Magnetic resonance imaging (MRI) data included ovarian mass distribution, maximum diameter of ovarian mass, ovarian mass features, degree of rectal invasion of the primary ovarian neoplasm or metastatic lesion, and amount of ascites. A model was established using multivariate logistic regression. RESULTS: By univariate and multivariate logistic regressions, CA-125 (P = 0.024, odds ratio [OR] = 3.798, 95% confidence interval [CI] = 1.24-13.32), NLR (P = 0.037, OR = 3.543, 95% CI = 1.13-12.72), and degree of rectal invasion of the primary ovarian neoplasm or metastatic lesion (P < 0.001, OR = 37.723, 95% CI = 7.46-266.88) were screened as independent predictors. The area under the curve values of the model in the training, test, and external validation groups were 0.860, 0.764, and 0.778, respectively. CONCLUSION: The clinical-radiological model based on T1-weighted dual-echo MRI can be used non-invasively to predict postoperative residual ovarian neoplasm or metastasis close to SOC in the rectum.

Normal ovarian sizes on MRI in pediatric patients: a preliminary study.

BACKGROUND: Ovarian enlargement is one of several findings of pathology, including ovarian torsion. With increasing use of MRI for acute abdominal pain in children, data for normal ovary size and appearance are needed. OBJECTIVE: To provide preliminary data on normal sizes of ovaries on MRI in pediatric patients. MATERIALS AND METHODS: This retrospective IRB-approved study included girls (5 to 17 years of age) with MRI examinations performed for indications not related to the ovaries from 2018 to 2022. For each MRI, coronal T2-weighted single shot fast spin echo and axial T2-weighted fat-saturated images were independently reviewed by three pediatric radiologists who recorded ovary visualization and ovarian linear measurements (3 planes). Ovarian volumes were calculated from linear measurements. Agreement among observers was calculated using kappa statistics and intraclass correlation coefficients. RESULTS: A total of 181 MRIs were reviewed. The left ovary was visualized in 166-176 (92-97%) cases (R1-R3) and the right ovary was visualized in 165-174 (91-96%) cases with excellent agreement among reviewers (left: K = 0.89 [0.84-0.94], right: K = 0.85 [0.79-0.91]). Interrater class coefficient (ICC) for largest single dimension of the ovary was left: 0.83 (CI 0.79-0.87) and right: 0.85 (CI 0.81-0.89). There were significant moderate to strong correlations between ovarian volume and age (left: 0.67 [0.58-0.75], right: 0.66 [0.57-0.74]). CONCLUSION: The ovaries can be adequately visualized and measured on MRI with excellent inter-reader agreement. This study serves as the foundation for developing normative values for ovarian volumes by age on MRI.

Use of excised ovaries for oocyte recovery by ultrasound guided follicular aspiration - Validation of an experimental model for research purposes in live mares ovum pick up.

Ovum pick-up (OPU) by transvaginal ultrasound guided follicle aspiration in mares is a common assisted reproductive technique used for oocyte recovery and in vitro production of horse embryos. There has been relatively little research into the factors influencing oocyte recovery in OPU from live mares. The objective of this study was to compare oocyte recovery and morphology of ultrasound-guided follicle puncture and aspiration in live mares and in postmortem excised ovaries, in order to validate an experimental model for research purposes of the efficiency of OPU in mares. Data from OPU performed in 12 mares from a commercial program (follicle numbers, oocyte recovery and oocyte morphology) were compared to that obtained from ultrasound-guided follicle puncture of 13 postmortem excised ovaries from slaughtered mares processed within 2 h of slaughter. In both groups, the OPU was performed by the same operator using the same equipment and OPU technique. The recovered oocytes per aspirated follicle was higher (P < 0.05) in the postmortem group (105/166, 63.2 %) than in live mares (138/261, 52.9 %). There was more (P < 0.05) expanded cumulus oocyte complexes in the postmortem than in the live mares (18 % vs. 2.9 %). Several oocytes (5 oocytes from 81 aspirated follicles) were found in the leaked fluid which overflowed during follicle flushing of postmortem ovaries. In conclusion, the higher recovery rate obtained in the excised ovaries and the finding of oocytes in the leaked fluid during OPU, suggests that there is still room for improvement in the in vivo OPU technique. Utilizing postmortem excised ovaries could offer an alternative for further research into factors affecting oocyte recovery and oocyte leakage during OPU procedures.

MRI features of ovarian teratomas with somatic-type malignancy and mature cystic teratomas.

PURPOSE: We evaluated the magnetic resonance imaging (MRI) features of ovarian teratomas with somatic-type malignancy (TSMs) and benign ovarian mature cystic teratomas (MCTs) to determine the diagnostic contribution of the MRI findings for differentiating these two teratomas. METHODS: We compared the MRI findings between ovarian TSMs (n = 10) and MCTs (n = 193), and we conducted a receiver operating characteristic (ROC) analysis to determine the MRI findings' contribution to the differentiation of TSMs from MCTs. RESULTS: The maximum diameters of whole lesion and the largest solid component in the TSMs were larger than those of the MCTs (p = 0.0001 and p < 0.0001, respectively). Fat tissue in solid components was seen in 73/116 (62.9%) MCTs but in none of the TSMs (p = 0.0001). Ring-like enhancement in solid components was seen in 60/116 (51.7%) MCTs and none of the TSMs (p = 0.0031). On dynamic contrast-enhanced MRI (DCE MRI), all of the solid components in the TSMs showed a high- or intermediate-risk time intensity curve (TIC), and those in 113 of the 116 (97.4%) MCTs showed a low-risk TIC (p < 0.0001). The area under the curve of the ROC analysis using the high-/intermediate-risk TIC on DCE MRI was the highest (0.99) for differentiating TSMs from MCTs: sensitivity 100%, specificity 97.4%, positive predictive value 75.0%, negative predictive value 100%, and accuracy, 97.6%. CONCLUSION: Compared to ovarian MCTs, ovarian TSMs are larger and have larger solid components with high- or intermediate-risk TICs on DCE MRI. Ovarian MCTs frequently show small solid components with fat tissue, ring-like enhancement, and a low-risk TIC on DCE MRI.

Diagnostic performance of contrast-enhanced ultrasound (CEUS) combined with Ovarian-Adnexal Reporting and Data System (O-RADS) ultrasound risk stratification for adnexal masses: a systematic review and meta-analysis.

AIM: A number of studies have reported that contrast-enhanced ultrasound (CEUS) imaging might be used for the early diagnosis of adnexal masses. A meta-analysis was performed to evaluate the diagnostic accuracy of CEUS combined with Ovarian-Adnexal Reporting and Data System (O-RADS) ultrasound risk stratification for adnexal masses. MATERIALS AND METHODS: Related articles were retrieved from PubMed, Web of Science, Embase, and the Cochrane Library in strict accordance with established standards, and data (including true positive, false positive, false negative, and true negative values) was extracted from the original articles. The Quality Assessment of Diagnostic Accuracy Studies 2 was used to evaluate the quality of articles and the possibility of bias. STATA 12.0 software was used to perform statistical analysis. RESULTS: Five articles that included 598 patients were analyzed in this meta-analysis. The pooled sensitivity and specificity of CEUS combined with O-RADS for the diagnosis of adnexal masses were 0.95 (95% confidence interval [CI]: 0.91-0.98) and 0.86 (95% CI: 0.79-0.91). Moreover, the positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio (DOR), and area under the curve (AUC) were 6.81 (95% CI: 4.61-10.08), 0.05 (95% CI: 0.03-0.11), 111.30 (95% CI: 65.32-189.65), and 0.97 (95% CI: 0.95-0.98), respectively. The pooled AUC and DOR for the detection of CEUS combined with O-RADS were superior to O-RADS US. CONCLUSION: Our findings revealed that O-RADS combined with CEUS can improve the diagnostic accuracy of ovarian adnexal masses.

Differentiating Benign From Malignant Ovarian Masses With Solid Components: Diagnostic Performance of CEUS Combined With IOTA Simple Rules and O-RADS.

OBJECTIVE: This study aimed to apply the International Ovarian Tumor Analysis (IOTA) Simple Rules (SR), the Ovarian-Adnexal Reporting and Data System (O-RADS) and contrast-enhanced ultrasound (CEUS) in an identical cohort of Chinese patients and to analyze their performance in discrimination of ovarian masses with solid components. METHODS: This was a two-center retrospective study that included a total of 94 ovarian lesions in 86 women enrolled from January 2018 to February 2023. The lesions were classified by using the IOTA terminology and CEUS was performed for the lesions exhibiting solid components on ultrasonography, IOTA SR and O-RADS were applied, and CEUS images were analyzed retrospectively. We assessed the time to wash-in, time to peak intensity (PI), PI compared to myometrium, and time to wash-out, and observed statistically significant differences between benign and malignant lesions in the first three parameters. CEUS characteristics were employed to determine CEUS scores for benign (score 0) and malignant (score 3) lesions. Subsequently, the lesions were reassessed based on the IOTA SR and O-RADS classifications and CEUS scores. The sensitivity, specificity, and area under the receiver-operating-characteristics curve (AUC) of the different models were also determined. RESULTS: Among the 94 ovarian lesions, 46 (48.9%) were benign and 48 (51.1%) were malignant. It was found that in the 60 lesions to which the SR could be applied, the sensitivity, specificity, and AUC was 0.900, 0.667, and 0.783, respectively. The sensitivity, specificity, and AUC of O-RADS was observed to be 1.000, 0.283 and 0.641, respectively. When SR and O-RADS were combined with CEUS, their sensitivity, specificity, and AUC values were increased to 0.917, 0.891, 0.904, and 0.958, 0.783, 0.871, respectively. CONCLUSION: IOTA SR and O-RADS exhibited relatively low specificity in differentiating malignant from benign ovarian lesions with the solid components, and their diagnostic performance can be significantly improved when combined with CEUS.

The effect of a flavonoid mixture containing diosmin, hesperidin and troxerutin in women with congestion syndrome associated to pelvic pain: a color Doppler ultrasonography study.

BACKGROUND: Pelvic congestion syndrome (PCS) is associated with chronic pelvic pain (CPP). The efficacy of flavonoids for treating PCS symptoms is still a matter of debate, and little has been published. The aim of this study was to assess the efficacy of a mixture of diosmin, troxerutin, and hesperidin in improving symptoms of patients with PCS, observing a direct effect on circulation by specific color Doppler ultrasonography (CDU) evaluations. METHODS: This was a pilot, prospective, independent, cross-over, daily-diary-based trial. Women were evaluated with CDU for 3 times (baseline, 60 days, 120 days). Data about N.=13 women who completed the study were analyzed. RESULTS: During the treatment, we recorded a significant reduction of intermenstrual and menstrual pain intensity (total points) (P<0.05). The satisfaction after treatment was significantly higher than after placebo (P<0.0001). A significant reduction in the diameter of the major ovarian vein (P=0.004 compared to placebo), associated with an increase in peak systolic velocity (P=0.01) and a corresponding significant increase in the Resistivity Index (P<0.0001) were recorded during treatment. CONCLUSIONS: The use of a mixture of diosmin, troxerutin and hesperidin in women with PCS can significantly help to manage typical symptoms of pelvic pain and it is associated with an evident Doppler effect on pelvic microcirculation.

The effect of subclinical hypothyroidism on hormonal and metabolic profiles and ovarian morphology in patients with polycystic ovary syndrome: a cross-sectional study.

OBJECTIVES: Polycystic ovary syndrome (PCOS) and subclinical hypothyroidism (SCH) are prevalent gynecological conditions. However, the interrelationship between the two remains elusive. This study aims to elucidate the association between these conditions and determine the potential impact of SCH on the physiological and metabolic characteristics of patients with PCOS. METHODS: This cross-sectional study enrolled 133 patients with PCOS from our Hospital. Participants were categorized into two groups: those with PCOS + SCH (n = 58) and those with PCOS (n = 75). Serum hormonal levels, metabolic markers, ovarian volume, and follicle count were compared between the groups. RESULTS: There was a significant difference in BMI between the two groups, with a higher prevalence of obesity in the PCOS + SCH group (p = .014). Compared to the PCOS group, patients with PCOS + SCH had significantly higher levels of TSH (p < .001), triglycerides (p = .025), and HOMA-IR (p < .001), while LH levels were significantly lower (p = .048). However, multivariate linear regression analysis revealed that TSH, triglycerides, LH, and HOMA-IR were not determinants for the occurrence of SCH in patients with PCOS. Additionally, there was a notable reduction in follicle count in the left ovary for the PCOS + SCH group compared to the PCOS group (p = .003), and the overall follicle diameter of the PCOS + SCH group was also smaller (p = .010). CONCLUSION: SCH may exert effects on the physiological and metabolic profiles of patients with PCOS. Further investigation into the relationship between these disorders is warranted to delineate their clinical implications.

Ultrasonographic and histopathological investigation of the effect of N-acetylcysteine on doxorubicin-induced ovarian and uterine toxicity in rats.

BACKGROUND: This study aimed to investigate the mitigating effect of N-acetylcysteine (NAC) on doxorubicin (DOX)-induced ovarian and uterine toxicity in rats using laboratory tests, ultrasonographic (US) imaging, and histopathology analysis. METHODS: Forty-eight rats were divided into six groups (n = 8) as follows: Group A (control) (0.5 mL saline administered intraperitoneally [IP]), Group B (a single 10 mg/kg dose of DOX administered IP on day 1), Group C (a single 10 mg/kg dose of DOX administered IP 24 h before sacrifice), Group D (100 mg/kg of NAC administered IP for 21 days), Group E ( a single 10 mg/kg dose of DOX administered IP on day 1 and 100 mg/kg of NAC administered IP for 21 days), and Group F (100 mg/kg of NAC administered IP for 21 days and a single 10 mg/kg dose of DOX administered IP 24 h before sacrifice). The ovaries were examined using B-mode US on days 1, 14, and 21, and the histopathological examinations of the ovaries and the uterus were undertaken after sacrifice on day 22. RESULTS: Histomorphological analyses showed that ovarian weight decreased after DOX administration in Group B but not in Group E. US revealed a transient increase in ovarian size in Group B and E, reverting to baseline levels over time, as well as a progressive increase in peritoneal fluid in Groups B and E. Group B exhibited a significant decrease in the thickness of the endometrium and myometrium and uterine cornual length, which was not observed in Group E. Histopathological examination showed that DOX caused a decline in follicular count, especially in primordial, secondary, and Graafian follicles, and resulted in follicular atresia, predominantly in Group B. Destructive degeneration/necrosis and vascular changes were most prominently seen in the corpus luteum of Groups C and B. In NAC-treated rats (Groups E and F), although germ cell damage was present, atretic follicles and vascular changes, such as hyperemia and congestion, were reduced. The anti-müllerian hormone (AMH) level was the highest in Group F. CONCLUSIONS: NAC, an antioxidant, attenuated DOX-induced gonadotoxicity in rats.
