RESUMO

OBJECTIVE: This study aims to compare the effects of microscopic microdiscectomy and microendoscopic discectomy on pain, disability, fear of falling, kinesiophobia, anxiety, quality of life in patients with lumbar disc herniation (LDH). METHODS: A total of 90 patients who underwent microscopic microdiscectomy (n = 40) and microendoscopic discectomy (n = 50) for LDH were included in this study. The patients' pain, disability, fear of falling, kinesiophobia, anxiety, and quality of life were evaluated before the surgery, in the early postoperative period and three months after. RESULTS: In patients who underwent microendoscopic discectomy, the results of pain, disability, fear of falling, kinesiophobia and anxiety were statistically decreased compared with the microscopic microdiscectomy in the early postoperative period and three months later (p < 0.05). Also, a statistically higher increase was observed in the general health perception of patients who underwent microendoscopic discectomy three months after the operation (p < 0.01). CONCLUSION: Microendoscopic microdiscectomy, remains the most effective and widely applied method with advantages on pain, quality of life, and improved physical functions.

RESUMO

Toxic doses of formaldehyde (FA) can cause oxidative damage and impair energy metabolism. Asprosin (ASP) and subfatin (SUB) are adipokines produced by adipose tissue that help regulate energy metabolism. We investigated the effects of carvacrol (CAR), an antioxidant with hepatoprotective properties, on ASP and SUB in rats exposed to FA using immunohistochemistry and biochemistry. We used 42 male Wistar albino rats divided into six groups of seven: group 1, untreated control; group 2, FA (10 ppm FA by inhalation 8 h/day, 5 days/week); group 3, CAR-20 (20 mg/kg); group 4, CAR-40; group 5, FA (10 ppm FA by inhalation 8 h/day, 5 days/week) + CAR-20 (20 mg/kg); group 6, FA (10 ppm FA by inhalation 8 h/day, 5 days/week) + CAR-40 (40 mg/kg). Levels of ASP and SUB, and total oxidant status (TOS) and total antioxidant status (TAS) in blood and liver tissue were measured using ELISA. ASP and SUB immunoreactivity was assessed using immunohistochemistry. The number of apoptotic cells was determined using the TUNEL method. The number of apoptotic cells in group 2 was increased compared to group 1. TOS in group 2 was increased compared to group 1. The numbers of apoptotic cells and TOS in group 3 were decreased compared to group 1. TOS was decreased in group 6 compared to group 2, but TOS was increased compared to group 1. We found ASP and SUB immunoreactivity in the liver. All alterations were reversed by addition of CAR. It appears that FA disrupts energy metabolism and CAR ameliorates the destructive effects of FA when used at appropriate doses, although CAR might be harmful at high doses.

RESUMO

BACKGROUND: Although current guidelines recommend cholecystectomy during the same admission in patients with mild acute biliary pancreatitis (ABP), it involves a waiting list most of the time. We aimed to assess the risk of complications and determine predictors during the waiting period for cholecystectomy after the first episode of ABP. METHODS: A prospective observational study was conducted in patients with mild ABP. Follow-ups were done by phone calls or using electronic health records for a maximum of 6 months after discharge or until cholecystectomy. RESULTS: A total of 194 patients were included in the study. Although all patients were referred to surgeons, only 81 (41.8%) underwent cholecystectomy within 6 months after discharge. During the observation period, gallstone-related biliary events (GRBEs) developed in 68 (35.1%) patients, which included biliary colic, recurrent ABP, acute cholecystitis, choledocholithiasis, gallbladder perforation, cholangitis, and liver abscess. The overall readmission rate was 25.2%, with 44.8% occurred within 4 weeks after discharge. The odds ratio of any complication was 1.58 (95% CI, 1.42 to 1.76, P =0.028) and 1.59 (95% CI, 1.42 to 1.78, P =0.009) in the patients who did not have surgery within 2 to 7 days and 8 to 15 days, respectively. A 4-fold increased risk of readmission was detected (95% CI, 1.16 to 13.70, P =0.019) if cholecystectomy was not performed within 31 to 90 days. The patients who developed complications had significantly higher C-reactive protein at admission, longer waiting time, and had 3 or more gallstones on imaging. CONCLUSIONS: Interval cholecystectomy was associated with a high risk of complications during the waiting period in patients with mild ABP.

RESUMO

The purpose of this study was to prospectively compare the measurement of skin-to-fascia distances in the neutral state, during manual elevation and by fascial elevation in patients who underwent laparoscopic surgery. In 53 patients, the distance between the skin and anterior wall of the rectus sheath was measured prospectively in following three different ways: (1) in neutral position, (2) during manual elevation and (3) during elevation of the fascia using forceps following an infraumbilical vertical skin incision. In all patients, subcutaneous tissue up to the fascia was dissected after a vertical skin incision. The skin-to-fascia distance of 30.9 mm (14.0-52.0 mm) in the neutral position decreased to 11.1 mm (0.0-26.0 mm) during the fascial elevation, while the mean distance increased to 40.1 mm (19-70 mm) during manual elevation (p < 0.001). In the closed laparoscopic entry technique in which a Veress needle is inserted into the peritoneum through a small incision, the needle should be introduced from the shortest distance between the skin and the peritoneum. Lifting the fascia with a proper surgical instrument in suitable patients could enable us to achieve this goal.

RESUMO

OBJECTIVE: In this study, we sought to investigate the effects of energy drink supplementation and treadmill exercise on the levels of free radicals, antioxidants, Angtpl8, Elabela, and lipid metabolism in rats. MATERIALS AND METHODS: A total of 28 male Wistar albino rats (4 weeks old, 101.96 ± 9.75 g) were included in the study. The rats were randomly divided into four equal groups: control, exercise, supplement, and exercise+supplement groups. At the end of the study, the rats were decapitated, and blood samples were tested for levels of Angptl-8, ghrelin, leptin, irisin, SOD, CAT, TBARS, total oxidant status, and total antioxidant status using enzyme-linked immunosorbent assay. Levels of blood lipids including triglycerides, total cholesterol, HDL-C, and LDL-C were studied using spectrophotometric method in an auto analyzer. RESULTS: Statistical analysis showed statistical significance in TBARS, LDL-C, irisin, Angptl-8, and Elabela levels of the exercise group; SOD and HDL-C levels of the supplement+exercise group; and total cholesterol levels in the supplement group (p < 0.05). Although there were differences between the groups in leptin, ghrelin, and CAT levels, they were not statistically significant (p > 0.05). CONCLUSIONS: As a result, it can be argued that treadmill exercise is important in regulating lipid metabolism and stimulating peptide hormones and receptors. Furthermore, consuming energy drinks without performing exercise or physical activity increases fat stores, and such increases in the critical organs and tissues may pose a threat to the body.

RESUMO

OBJECTIVE: Cervical Inlet Patch (CIP) is an interesting entity that is little known and often neglected by endoscopists. It has always been reported as less than expected. In this article, for the first time in the literature, we want to measure the true prevalence of CIP in a center dealing with specific esophageal diseases. PATIENTS AND METHODS: From October 2020 to October 2021, a total of 283 patients, aged 15-95 years, with mainly dyspeptic and reflux-like complaints were included in this study. All endoscopic procedures were performed carefully by a single endoscopist. Patients were examined for any possible presence of CIP, with adequate sedation and time. RESULTS: The prevalence of CIP, which was the primary aim of our study, was detected at a rate of 14.8%. Most CIP was observed as a single lesion (73.8%), and many of them (45.2%) were larger than 10 mm. Plenty of patients had upper endoscopy due to dyspeptic complaints, but only 2.5% of them presented with a preliminary diagnosis of laryngeal reflux. CONCLUSIONS: The true CIP prevalence is higher than reported before. Our result is the highest prevalence rate of CIP was detected in Turkey. In this regard, data coming from centers dealing with specific esophageal diseases may be more reliable and true.

RESUMO

OBJECTIVE: Gestational diabetes mellitus (GDM) is a type of diabetes that affects from 3.8% to 6.9% of pregnancies worldwide, causing significant mortality and unfavorable obstetric outcomes, such as delivery trauma and macrosomia risk. The fundamental processes of this metabolic disorder that first appeared during pregnancy are still unknown. Tissue hormones, particularly adipokines, have aided in understanding the pathophysiology of numerous disorders in recent years. This study aims to determine if Apelin-13 (APLN-13), Apelin-36 (APLN-36), Elabela (ELA), and nitric oxide (NO) molecules have all a part in the pathophysiology of GDM. PATIENTS AND METHODS: The study included 30 pregnant control women and 30 pregnant women who had been diagnosed with GDM in the second trimester and whose body mass index and age were compatible with each other. Blood samples were collected from 60 participants during the second trimester (30 control pregnant women and 30 GDM pregnant women) and postpartum (17 controls vs. 14 GDM). In these blood samples, the amounts of APLN-13, APLN-36, ELA, and NO were studied using the ELISA method. In addition, the participants' glucose, lipid profiles, and other parameters were obtained from the hospital record files. At postpartum, 29 pregnant women (13 control and 16 pregnant women with GDM) dropped out of the study without explanation. RESULTS: In the second trimester and postpartum plasma of mothers with GDM, APLN-13, APLN-36, NO, and ELA molecules were found to be significantly higher (< 0.05), compared to those of the control mothers, while APLN-13, APLN-36, NO values were significantly lower (0.05). While APLN-13, APLN-36, NO amounts in mothers with GDM were positively correlated with glucose amounts, they were negatively correlated with ELA amounts. Similarly, the triglyceride amounts in mothers with GDM were positively correlated with APLN-13, APLN-36 and NO, while they were negatively correlated with the ELA amounts. Due to gestational diabetes, APLN-13, APLN-36, NO, glucose, and triglyceride increased, and ELA decreased. CONCLUSIONS: It is predicted that the glucose increase in GDM is because Apelins reduce glucose transport to erythrocytes by inhibiting the sodium-dependent glucose transporter (SGLT) and that the increase in triglyceride and NO may be associated with high glucose levels in GDM. As a result, we believe that the above-mentioned chemicals may cause GDM Pathology by triggering one another.

RESUMO

OBJECTIVE: The melanocortin system is an important neural system underlying the control of body weight and food intake. This system has recently received great attention as a potential target for obesity treatment. Therefore, the objective of this study was to find out the leptin-melanocortin pathway before and after Laparoscopic Sleeve Gastrectomy (LSG) in obese patients. PATIENTS AND METHODS: The study was carried out with a total of 144 individuals in 3 groups [control, obese group before LSG and obese group after LSG (who underwent LSG one year ago)]. The amount of leptin (LEP), leptin receptor (LEPR), tropomyosin receptor kinase receptor B (TrkB), brain-derived neurotrophic factor (BDNF), pro-opiomelanocortin (POMC) and melanocortin-4 receptors (MC4R) molecules were measured by using Enzyme-Linked Immunosorbent Assays. RESULTS: A statistically significant difference was found between the groups in terms of body mass index (BMI) values (p = 0.001). There was also statistically significant difference present between obese before LSG group and obese after LSG group regarding the levels of LEP, TrkB, BDNF and proteins (p < 0.05). A decline was determined in the LEP and BDNF levels one year follow-up after LSG. CONCLUSIONS: The evidence suggests that the leptin melanocortin pathway strictly regulates food intake and BMI before and after LSG surgery. This pathway should be kept under control for effectively reducing food intake and body weight in the treatment of obesity.

RESUMO

PURPOSE: Central serous chorioretinopathy (CSCR) is an eye disease of unknown etiology that presents with reduced visual acuity, choroidal thickening (distance between Bruch's membrane and the chorioscleral border), and subretinal fluid leakage. In the present study, the goal was to investigate the role of the interrelated tenascin C, metalloprotein-1, BAX, BCL2, subfatin and asprosin molecules in the pathogenesis of CSCR. METHOD: Thirty CSCR patients and 30 controls were included. CSCR was diagnosed by optical coherence tomography imaging. A 5mL blood sample was collected from all participants after overnight fasting. Compounds in the blood samples were studied with the Enzyme-Linked Immunosorbent Assay (ELISA) method. RESULTS: Patients with CSCR were found to have macular thickening (P: 0.08) and statistically significantly reduced visual acuity (P: 0.034) compared to controls. With regard to serum parameters, there were statistically significant increases in tenascin C, metalloprotein-1, BAX, BCL2, subfatin and asprosin levels compared to controls. We found a positive correlation between macular thickness and tenascin C (r+0.670, P<0.001), metaloprotein-1 (r+0.714, P<0.001), BAX, BCL2 (r+0.771, P<0.001), subfatin and asprosin levels and a negative correlation between visual acuity and tenascin C (r+0.605 P<0.001), metaloprotein-1 (r+0.704, P<0.001), BAX, BCL2 (r+0.738, P<0.001), subfatin and asprosin levels. CONCLUSION: The molecules studied herein were negatively correlated with visual acuity and positively correlated with macular thickness, suggesting that these molecules might have a role in the pathogenesis of CSCR. Thus, we predict that these molecules could be new candidates for the diagnosis and follow-up of CSCR in the future.

RESUMO

Renalase (RNLS) is synthesized mainly in renal tissues. The function of RNLS in cancerous renal tissues has not been investigated. We investigated the synthesis of RNLS in chromophobe renal cell carcinoma, papillary renal cell carcinoma and clear cell renal cell carcinoma with Fuhrman grades (FG): FG1, nucleoli are absent or inconspicuous and basophilic; FG2, nucleoli are conspicuous and eosinophilic and visible but not prominent; FG3, nucleoli are conspicuous and eosinophilic; FG4, extreme nuclear pleomorphism, multinucleate giant cells, and/or rhabdoid and/or sarcomatoid differentiation. We used 90 tissue samples including 15 healthy controls, 15 chromophobe renal cell carcinoma tissues and 10 papillary renal cell carcinoma renal tissues: 12 FG1, 14 FG 2, 14 FG 3 and 10 FG4. RNLS in the tissue samples was measured using enzyme linked immunosorbent assay and immunostaining of RNLS in these tissues. RNLS was significantly greater in the chromophobe renal cell carcinoma and papillary renal cell carcinoma tissues than the control. The least amount of RNLS was found in the renal tissues of clear cell renal cell carcinoma FG1; the amount of RNLS increased as the FG grades increased. Because RNLS increased significantly in renal tissues due to cancer, except for clear cell renal cell carcinoma FG1, RNLS may be useful biomarker for distinguishing grades of renal cancer. Because RNLS increases cell survival, anti-RNLS preparations may be useful for treating cancer in the future.

RESUMO

We investigated the effects of exposure to formaldehyde on transient receptor potential melastatin 2, betatrophin, total oxidant status and total antioxidant status in rat liver and kidney tissues. We also investigated the effects of carnosine on formaldehyde treated animals. We used 28 male rats divided ramdomly into four groups of seven: untreated control group, carnosine treated group, formaldehyde treated group and formaldehyde + carnosine group. The experiment lasted for four weeks. Betatrophin levels in samples were measured uing the enzyme-linked immunosorbent assay, and total oxidant status and total antioxidant status were measured using REL assay diagnostic kits. We detected betatrophin and transient receptor potential melastatin 2 immunoreactivity using immunohistochemistry and assessed apoptosis using terminal deoxynucleotidyl transferase dUTP nick end labeling. The betatrophin and total antioxidant status levels decreased in kidney, liver and plasma following exposure to formaldehyde, while total oxidant status and terminal deoxynucleotidyl transferase dUTP nick end labeling positivity increased. Carnosine supplementation reversed histopathology and biochemical damage caused by formaldehyde. We suggest that carnosine treatment may be useful for protecting persons exposed to formaldehyde.

RESUMO

INTRODUCTION: We aimed to investigate the effects of changes in sleep architecture on long-term clinical outcome in patients with Parkinson's disease (PD) who underwent deep brain stimulation of subthalamic nuclei (STN DBS). METHODS: We followed up eight PD patients before and three years after STN DBS surgery. In addition to clinical assessments, polysomnography (PSG) followed by multiple sleep latency tests was performed before and after STN DBS, while stimulator was ON and OFF. RESULTS: Subjective sleep latency was significantly decreased (P=0.033) and sleep duration was increased (P=0.041), as measured by Pittsburgh sleep quality index. Latency to REM sleep stage was shortened after surgery with STN DBS ON (P=0.002). Index of central type of abnormal respiratory events was significantly increased while stimulator was ON (P=0.034). Total number of major body movements was found to be increased when stimulator was turned OFF (P=0.012). Among PSG data obtained during STN DBS ON, it was observed that duration of N3 sleep was negatively correlated with UPDRS scores at 1st (P=0.038) and 3rd (P=0.045) post-operative years. Among PSG variables during STN DBS OFF, durations of N3 sleep (P=0.017) and REM sleep (P=0.041) were negatively correlated with UPDRS scores at post-operative 1st year. CONCLUSION: Disturbances in sleep architecture are associated with higher UPDRS scores and worse prognosis at 1st and 3rd post-operative years. Similar results obtained while stimulator was OFF at the end of 1st year support the presence of microlesion effect after STN DBS, which is probably not long lasting.

RESUMO

We investigated the expression of irisin in renal cancers using immunocytochemistry. Irisin has been reported to exhibit anticancer properties. The study groups consisted of 22 cases each of control renal tissue, oncocytoma, chromophobe renal cell carcinoma (RCC), clear cell RCC (Fuhrman nuclear grades 1, 2, 3 and 4) and papillary RCC. We evaluated 10 slides for each of 176 cases. Slides were immunostained for irisin and histoscores were calculated for the prevalence and strength of immunostaining. Fuhrman nuclear grade 1, 2, 3 clear cell RCC and papillary RCC exhibited no irisin immunoreactivity. Irisin immunoreactivity was observed in some Fuhrman nuclear grade 4 RCCs. We found a significant decrease in irisin staining in chromophobe RCC compared to the control. Immunoreactivity in the oncocytoma tissue was comparable to the control group. Irisin immunoreactivity in chromophobe RCC decreased and no immunoreactivity was observed in Fuhrman nuclear grade 1, 2, 3 clear cell RCC and papillary RCC. Immunistochemical screening of irisin in renal oncocytomas and renal cancers may be useful for differential diagnosis.

RESUMO

AIM: The aim of this study was to investigate ELABELA (ELA) expression in benign and malignant renal tissues and expression differences in different nuclear grades of clear cell carcinomas. MATERIALS AND METHODS: Patients that underwent surgery due to renal masses between the years of 2007 and 2017 were used. Control renal tissues (n = 23), papillary RCC (n = 23), clear cell RCC (CcRCC) [Fuhrman Grade1 (n = 23), Fuhrman Grade2 (n = 23), Fuhrman Grade3 (n = 23), Fuhrman Grade4 (n = 23)], and chromophobe RCC (n = 23) were included to the study. The Independent samples t-test was used for 2-point intergroup assessments and the one-way analysis of variance and posthoctukey test was used for the others. Values of P < 0.05 were considered statistically significant. RESULTS: ELA immunoreactivity was observed in proximal and distal tubules in the kidney, but not in glomeruli in control tissues. When compared with control kidney tissue, a statistically significant increase was observed in ELA immunoreactivity in renal oncocytoma. In the chromophobe RCC, ELA immunoreactivity was significantly lower than control kidney tissue, whereas papillary RCC did not show ELA immunoreactivity. However, compared with control kidney tissue, ELA immunoreactivity was not observed in Fuhrman Grade 1 and Grade 2 CcRCC. Also, there was a significant decrease at Fuhrman Grade 3 and Grade 4 CcRCC compared with control kidney tissues. In the statistical analysis of ELA immunoreactivity among the Fuhrman nuclear grades of CcRCCs, The ELA immunoreactivity was higher at Grade 4 CcRCC than Grade 1, Grade 2, and Grade 3. CONCLUSION: ELA is a usefull molecule to differentiate benign and malign renal tumors. But further broad and comprehensive studies are needed to investigate cellular and molecular mechanisms of ELAs on malign transformation.

RESUMO

INTRODUCTION: Congenital salivary gland anlage tumour of the nasopharynx is a lesion which usually presents with nasal and upper respiratory tract obstruction in the neonatal period. Timely diagnosis is essential to prevent the occurrence of respiratory complications in later childhood. CASE REPORT: We present a 8-year-old boy complaining from difficulty in breathing and breastfeeding in the neonatal period due to an adenoid-like nasopharyngeal mass. Histological examination revealed solid and cystic squamous nests and numerous duct-like structures within collagenised stroma. Both epithelial and myoepithelial differentiation were noted in the tubular component. DISCUSSION: A review of the clinical and histopathological features of published cases revealed that ancient lesions showed more prominent and complex epithelial component and more collagen rich stroma. We would like to suggest the possibility of salivary gland anlage tumour to be considered in the differential diagnosis of neonatal respiratory distress cases.

RESUMO

This study aimed to measure the serum endocan level of patients with erectile dysfunction (ED) and to investigate the possible association between this and vasculogenic severe ED. We performed a prospective analysis of 86 consecutive patients affected by ED. Patients were divided into severe ED (IIEF-5 score < 7) and mild or moderate ED (IIEF-5 score > 7). A strong negative correlation was found between serum endocan levels and peak systolic velocity (p < .001 and r = -.665) in men with severe ED. Univariate logistic regression analysis demonstrated that tobacco consumption (p < .05), serum total 25-hydroxyvitamin D (p < .01), serum endocan levels (p < .01), peak systolic velocity (p < .01), hypertension (p < .001), dyslipidaemia (p < .001), metabolic syndrome (p = .026) and a history of a cardiovascular event (p < .001) significantly increase the risk of severe ED. In the multivariate logistic regression model, we also found that age, hypertension, metabolic syndrome, cardiovascular events and higher serum endocan levels were independently associated with severe ED. Circulating endocan may be used in daily practice as a new marker that correlates with cardiovascular risks and the severity of ED disease.

RESUMO

Testicular torsion (TT) is a common urological problem in the field of pediatric surgery. The degree and duration of torsion determines the degree of testicular damage; however, its effects on the expression of octanoylated ghrelin and nucleobindin 2 (NUCB2) /nesfatin-1 synthetized from testicular tissue remain unclear. We explored the effects of experimentally induced unilateral TT on serum and contralateral testicular tissue ghrelin and NUCB2/nesfatin-1 levels, and determined whether N-acetyl cysteine (NAS) treatment had any effects on their expression. A total of 42 Wistar Albino strain rats were divided into 7 groups: Group (G) I control, GII sham, GIII 12-hour torsion, GIV 12-hour torsion + detorsion + 100 mg/kg NAS, GV 24-hour torsion, GVI 24-hour torsion + detorsion + 100 mg/kg NAS, and GVII 100 mg/kg NAS. Octanoylated ghrelin and NUCB2/nesfatin-1 concentrations were evaluated in serum using the ELISA method and in testicular tissue with immunohistochemical methods. Immunoreactivity of octanoylated ghrelin significantly increased in GI compared to GIII, GV, and GVI (p<0.05). NUCB2/nesfatin-1 immunoreactivity increased in GV and GVIII relative to GI (p<0.05). In the 12-hour torsion group, a significant decrease in octanoylated ghrelin levels with NAS treatment was observed; however, in the 24-hour torsion group, a significant decrease was not observed. In the 12-hour torsion + NAS treatment group, a significant change was not observed in NUCB2/nesfatin-1 expression. Following 24-hour torsion, an increase in NUCB2/nesfatin-1 levels was observed, and NAS treatment did not reverse this increase. It was determined that increases in the expression of octanoylated ghrelin and NUCB2/nesfatin-1, the latter of which was a result of TT, reflect damage in this tissue. Importantly, NAS treatment could prevent this damage. Thus, there may be a clinical application for the combined use of NAS and octanoylated ghrelin in preventing TT-related infertility.

RESUMO

Purpose ofinvestigation: Influence of the patients' age are not well established to predict the malignancy potential of adnexal masses. This study was conducted to evaluate the impact of women's age on both histopathology and malignancy potential of adnexal masses. MATERIALS AND METHODS: This is a retrospective chart review study. Patients who were operated for suspected adnexal masses were included in the study. Malignancy potentials of tumors were divided in benign and at least borderline in univariate and multivariate analyses. Univariate analyses and RR calculations were performed according to malignancy potential for age, serum cancer antigen-125 (CA-125) levels and menopause status. RESULTS: A total of 1,138 women were included for this study; median age was 39 (16-92) years. Patients > 50 years had 5.920 times higher risk (95% CI 4.091-8.566; p = 0.0001) of having at least borderline tumor compared the younger group. The risk of at least borderline pathology was calculated as 3.723 (95% CI 2.595-5.342;p = 0.0001) in patients with CA 125 ≥ 35 IU/ml compared to the others. In multivariate analyses, only ≥ 35 IU/ml CA 125 level and > 50 years age groups were defined as independent variables for having at least borderline tumor. (OR: 4.456, 95% CI 2.982-6.659, p = 0.0001 and OR: 3.134, 95% CI 1.435-6.843, p = 0.004, respectively). CONCLUSION: In this study; the age of > 50 years was detected as an independent factor for having at least borderline pathology for adnexal masses. The data from these results might be used as a differential diagnostic tool in a new combination for benign and malignant adnexal masses in future studies.
