ObjectivesTo investigate the expression of sulfatides in the tissue homogenates of malignant ovarian tumors, benign ovarian tumors, and control tissues and to study the relation between this marker and other clinico-pathological criteria such as the tumor type, grade of differentiation, surgical stage and ovulatory years.DesignCross-sectional study.SettingDepartment of Obstetrics and Gynecology and Department of Biochemistry, Assuit university hospital.SubjectsForty-six patients had malignant ovarian tumors. Sixteen patients had benign ovarian neoplasm. Thirty patients, with normal ovaries, represented the control group.MethodsA sample of the tumor or from the normal ovary (the control group) was sent for histopathological and biochemical examination. Sulfatides were measured by a rapid and sensitive spectrophotometric method.ResultsThere was a significant rise in benign tumors [median and range 43 (38–53)], than in the control group, 21 (18–31), P-value = 0.000. In malignant tumors, the median value of sulfatides was significantly higher than in benign tumors [127 (71–193), P-value = 0.000]. Sulfatides were significantly higher in patients with more ovulatory years and tumors of advanced stages (stage III/IV) and poor differentiation.ConclusionsSulfatides may play a role in the pathogenesis of benign and malignant ovarian tumors. It may also predict advanced stages in patients who are apparently early stage. It is also a candidate to study of their association with response to chemotherapy.

Objective To evaluate the performance of mesothelin, CA125, HE4 and ROMA index in the detection of malignant ovarian tumors. Study Design This is a cross-sectional study including 199 women with adnexal masses (67 with malignant tumors and 132 with benign tumors) and 150 healthy women (controls). We used a recursive multivariate partitioning algorithm to assess the contribution of each of the serum markers and the ROMA index to the discrimination of women with malignant tumors. Also, the areas under the ROC curves (AUC) for each of the serum markers and for the ROMA index were compared using the Venkatraman's projection-permutation test. Results In the recursive model, CA125 had the best performance in discriminating women with malignant tumors. In women with normal-range CA125 levels, none of the other markers contributed to the discrimination of women with malignant tumors. In women with elevated CA125 levels, elevated HE4 levels were associated with an increased risk of harboring a malignant tumor. The AUC for mesothelin was smaller than that for all the other curves, and both the ROMA index and CA125 had better AUC than HE4. Conclusion In women with normal CA125 levels, neither mesothelin nor HE4 contributed to discriminate women with malignant ovarian tumors; however, for women with elevated CA125 levels HE4 may help discriminating those who have a malignant ovarian tumor.

5579 Background: Ovarian cancer (OVCA) is a lethal malignancy of women with a distinct pattern of metastasis through peritoneal dissemination. Sustained exposure of the ovaries to oxidative stress due to inflammatory processes including ovulatory genotoxicity, makes the ovarian microenvironment conducive to malignant cell proliferation. GRP78 is a stress-inducible protein which resides in the endoplasmic reticulum of the cell. Thus GRP78 may be a marker of ovarian tumor associated stress and could represent a therapeutic target for OVCA. The goal of this study was to examine if GRP78 expression increases in association with OVCA development and determine the molecular mechanism of its increase in ovarian tumors. Methods: All tissues were collected from patients who underwent surgery and processed for immunohistochemistry (IHC), proteomic study (2D-WB) and miRNA expression. Expression of GRP78 was examined in paraffin sections of normal ovaries (n = 20), benign (serous cystadenoma, n = 15 and cystadenofibroma, n = 5) and ovaries with papillary serous carcinoma at early stage (n= 20 at stages I and II) and late stage (n = 20, stages III and IV) by IHC and confirmed by 2D-WB (representative samples). Changes in miRNA-181 (post-translation regulator of GRP78) expression were examined by qRT-PCR. Results: GRP78 expression by normal ovarian surface epithelium and epithelium of benign tumors was very weak. In contrast, the intensity of GRP78 expression was significantly (p<0.05) high in early stage OVCA and increased further in late stage OVCA. An immunoreactive band of 78kDa detected by 2D-WB confirmed IHC observations. In contrast, expression of miRNA-181 by malignant tumors significantly (p<0.05) decreased as the tumor progressed to late stages. Conclusions: The results of the present study suggest that GRP78 expression is associated with the development and progression of malignant ovarian tumors. Increase in GRP78 expression was associated with the down-regulation of miRNA-181. Expression of GRP78 by malignant ovarian epithelium represents a potential marker with usefulness for targeted drug delivery. Support: Elmer and Sylvia Sramek Foundation.

AimTo retrospectively investigate the pre-operative clinical factors and ultrasonographic features that influence the accuracy of the intraoperative frozen section (IFS) of ovarian tumors.Patients and methodsWomen with ovarian tumors that underwent IFS in one tertiary medical center were recruited from January 2010 to December 2018. Demographic and clinical data of these women were retrieved from medical records in the hospital’s centralized database.ResultsA total of 903 ovarian tumors were enrolled, including 237 (26.2%) benign, 150 (16.6%) borderline tumor, and 516 (57.2%) malignant. The overall accuracy of IFS among all specimens was 89.9%. The sensitivities of IFS in diagnosing borderline tumors (82.0%) and malignant tumors (88.2%) were lower than in diagnosing benign tumors (98.7%, p &lt;0.001, Z-test). The specificity of diagnosing malignant tumors (99.7%) was significantly higher than that of diagnosing benign tumors (94.7%, p &lt;0.001, Z-test). The group with discordant IFS and final paraffin pathology (FPP) had younger age (47.2 ± 14.0 vs. 51.5 ± 11.8 years, p = 0.013, Mann–Whitney U test), and higher percentage of early-stage disease (85.2% vs. 65.1%, p = 0.001, chi-square test) and mucinous (39.3% vs. 3.3%) and endometrioid histologic types (34.4% vs. 20.2%) than the concordant group (all by chi-square test). Menopause (OR 0.34, 95% CI 0.15–0.76, p = 0.009), multicystic tumor in ultrasound (OR 2.14, 95% CI 1.14–4.01, p = 0.018), and ascites existence (OR 0.33, 95% CI 0.14–0.82, p = 0.016) were factors related to the discordant IFS by multivariate analysis.ConclusionsIFS has good accuracy in the diagnosis of ovarian tumors. We recommend more frozen tissue sampling for sonographic multicystic tumors in premenopausal women to improve the accuracy of IFS.

Background: Thyroid diseases occur more frequently in people exposed to ionizing radiation, but the relationship between occupational exposure to ionizing radiation and thyroid pathologies still remains unclear. Objective: To evaluate the prevalence of thyroid diseases in healthcare workers exposed to low-level ionizing radiation compared with a control group working at the University Hospital of Bari, Southern Italy, and living in the same geographical area, characterized by mild iodine deficiency. Methods: We ran a cross-sectional study to investigate whether healthcare workers exposed to ionizing radiation had a higher prevalence of thyroid diseases. Four hundred and forty-four exposed healthcare workers (241 more exposed, or “A Category”, and 203 less exposed, or “B Category”) and 614 nonexposed healthcare workers were enrolled during a routine examination at the Occupational Health Unit. They were asked to fill in an anamnestic questionnaire and undergo a physical examination, serum determination of fT3, fT4 and TSH, anti-TPO ab and anti-TG ab and ultrasound neck scan. Thyroid nodules were submitted to fine needle aspiration biopsy when indicated. Results: The prevalence of thyroid diseases was statistically higher in the exposed workers compared to controls (40% vs 29%, adPR 1.65; IC95% 1.34-2.07). In particular, the thyroid nodularity prevalence in the exposed group was approximately twice as high as that in the controls (29% vs 13%; adPR 2.83; IC95% 2.12-3.8). No statistically significant association was found between exposure to ionizing radiation and other thyroid diseases. Conclusion: In our study, mild ionizing radiation-exposed healthcare workers had a statistically higher prevalence of thyroid diseases than the control group. The results are likely due to a closer and more meticulous health surveillance programme carried out in the ionising radiation-exposed workers, allowing them to identify thyroid alterations earlier than non-exposed health staff.

Background: Cancer antigen 19-9 (CA 19-9) is a tumor-associated mucin glycoprotein antigen that may be elevated in healthy individuals as well as in patients with benign and malignant tumors. It is useful in the management of pancreatic and other gastrointestinal tumors. CA 19-9 is also elevated in benign and malignant ovarian tumors. Aim: To study the pattern of serum CA19-9 in complex ovarian tumors. Methods: The study design was descriptive, based on data collected from medical records. Patients with a complex ovarian mass, who were investigated with CA 19-9 and had undergone surgery, wereincluded in the study. The study duration was 2 years from January 2014 to December 2015. A total of 273 patients (119 - benign and 154 malignant) with complex ovarian mass and elevated CA 19-9 underwent surgery during the study period. Results: CA 19-9 was elevated in 55 patients (20%). Of these, 23 patients had benign tumors while 32 had malignant tumors.Among patients with benign tumors, 21 had dermoid, 23 had mucinous tumors and 75 had other types of tumors. CA 19-9 was elevated in 10 (47.6%) of the dermoids, 7 (30.4%) of the mucinous tumors and 6 (8%) of the other benign tumors. Among patients with malignant tumors, 138 were epithelial and 16 were non epithelial tumors. Of the epithelial tumors, 31 were mucinous and 107 were non mucinous types. Overall, 29 (21%) had elevated CA 19-9. Of the epithelial tumors, 22.6% of the mucinous type and 20.6% of the non mucinous type had elevated CA 19-9. Among the non-epithelial tumors, 3 (18.8%) had elevated CA19-9. Conclusion: CA 19-9 is elevated in several conditions but most likely to be raised in dermoid cysts and mucinous tumours. CA19-9 levels need to be interpreted along with clinical and radiological findings.

ObjectiveThe objectives were to evaluate the risk of malignant adnexal tumors in women with nongynecologic malignancies and to identify variables associated with the risk of malignant adnexal tumors.MethodsThe eligibility criteria included the diagnosis of a nongynecologic malignancy and adnexal tumors, which were resected or subjected to biopsy at our institute between 1999 and 2010. The risk of malignant adnexal tumors was assessed by dividing the number of patients with metastatic tumors to the adnexa or primary adnexal cancers by the total number of patients. The association of clinicopathologic variables with the risk of malignant adnexal tumors was evaluated using the Fisher exact test and binary logistic regression analysis. In patients with metastatic tumors to the adnexa, the association of clinicopathologic variables with overall survival after adnexal surgery was examined using the log-rank test.ResultsIn 166 patients with adnexal tumors, 41 benign tumors, 113 metastatic tumors to the adnexa, and 12 primary adnexal cancers were diagnosed. Age older than 46 years, a tumor type associated with a high risk for malignant adnexal tumors, and bilateral tumors significantly increased the risk of malignant adnexal tumors. The overall survival of the patients with stomach cancer was significantly worse than the patients with colorectal or breast cancers.ConclusionOne hundred twenty-five of the 166 patients with nongynecologic malignancies who had adnexal tumors managed surgically were shown to have malignant tumors, and most of the tumors were metastatic from primary sites. The risk of malignant adnexal tumors was associated with age, nongynecologic malignancy, and bilaterality.

ABSTRACT Objective: To investigate whether there is an association between suicidal ideation (SI) and allergic diseases in adults. Methods: This was a comparative cross-sectional study involving individuals ranging from 20 to 50 years of age recruited from a university hospital in the city of Guadalajara, Mexico. We included patients with a confirmed diagnosis of allergic asthma, those with a confirmed diagnosis of allergic rhinitis, and healthy controls. All subjects completed the Beck Depression Inventory-II (BDI-II), which includes an item that evaluates the presence of suicidal thoughts or desires within the last two weeks, in order to identify SI. Results: The sample comprised 115 patients with allergic asthma, 111 patients with allergic rhinitis, and 96 healthy controls. The number of individuals identified with SI in the three groups were, respectively, 17 (14.8%), 13 (11.7%), and 8 (8.3%). Regarding the presence of SI, no statistically significant association was found in the allergic asthma group (OR = 1.98; 95% CI: 0.78-4.64; p = 0.154) or in the allergic rhinitis group (OR = 1.46; 95% CI: 0.58-3.68; p = 0.424) when they were compared with the control group. However, the presence of depression was associated with SI in the three groups: allergic asthma (OR = 12.36; 95% CI: 2.67-57.15; p = 0.001); allergic rhinitis (OR = 6.20; 95% CI: 1.66-23.14; p = 0.006); and control (OR = 21.0; 95% CI: 3.75-117.36; p < 0,001). Conclusions: In comparison with the control group, no association was found between SI and the groups with allergic diseases. In contrast, there was association between SI and depression in the three groups.

Background: The aim of this study was to evaluate the incidence and histological type of lesions affecting the ovaries and to analyze employed methods of invasive treatment. Materials&Methods: Medical records of patients who were treated surgically for ovarian tumors in the years 2015 -2019 were reviewed. The study group was comprised of 31 female patients. Results: During 5 years time, there were 31 girls in the age from 3 months to 17 years hospitalized in the department. The mean age was 11 years. Histopathological examination was performed in all of these cases. 12 patients were diagnosed with malignant lesion, 19 with benign lesion. The most commonly diagnosed malignant tumors were a dysgerminoma and a mixed germ cell tumor. In the group of benign lesions, the most frequent tumor type was mature teratoma. The first occurring symptom was abdominal pain. Some of the lesions were diagnosed accidentally during ultrasonography. The diagnostics was expanded depending on the size of the tumor, staging and clinical condition of the patient. All the patients were treated surgically, 16 of them underwent laparoscopic surgery. Torsion of the ovary or oviduct was observed in 3 cases. Chemotherapy was introduced in 8 cases as complementary treatment. Conclusions: The most commonly diagnosed tumor was mature teratoma. Ultrasonography is the most frequent method of the ovaries’ examination. Ovarian lesions are characterized by non-specific clinical symptoms, which is associated with prevalent incidental detection during ultrasonography.

Objective: to determine the prevalence of explained and unexplained recurrent miscarriages (RM) and to find out if there is a significant relationship between recurrent miscarriages and consanguinity. Methods: A cross sectional in which the cases group included all women with RM attending the outpatient clinic at Sultan Qaboos University Hospital from July 2006 to April 2012 and the controls group included women with no history of RM after matching them with cases for age (case to control ratio was 1:1). The main outcome measures were the prevalence of consanguinity in women with or without recurrent miscarriages. Results: During study period a total of 290 women with RM were seen. Of which, 150 (51.7%) women had unexplained RM. Control group with no history of RM were 300 women. Consanguinity rate among cases (49.5%) %) was less than the controls (52.7 %%). Both first cousin and second cousin marriages were more common in the controls than the cases and it was not statistically significant (p value 0.476, chi squared test). Conclusion: In this study we found that more than half of RM cases were unexplained and there was no significant association between RM and consanguinity.
