RESUMO

BACKGROUND: It is known that the increase in oxidants and proinflammatory cytokines, as well as the decrease in antioxidants, play a role in ovarian ischemia-reperfusion (I/R) injury. The antioxidant and anti-inflammatory properties of ramipril have been studied in various diseases. This study aims to investigate the effect of ramipril on I/R-induced ovarian damage in rats. METHODS: Rats were divided into healthy (HG), sham (SG), ovary I/R (OIR), and ramipril + ovary I/R (ROIR) groups (n = 6/each group). One hour before the surgical procedures, ROIR was given 2 mg/kg ramipril. The lower abdomen of the SG, OIR, and ROIR was surgically opened. Right ovarian tissues of OIR and ROIR were subjected to 2 hours of ischemia and 6 hours of reperfusion. Then, all animals were euthanized, and their right ovaries were removed. Ovarian tissues were examined for oxidants (malondialdehyde), antioxidants (total glutathione, superoxide dismutase, and catalase), and proinflammatory cytokines (nuclear factor kappa-B, tumor necrosis factor-alpha, interleukin 1 beta, and interleukin-6) analysis was performed. Tissues were examined histopathologically. RESULTS: The ovarian tissue of the OIR, which underwent the I/R procedure, exhibited a significant increase in oxidant and proinflammatory cytokine levels, along with a decrease in antioxidant levels (P < .001). Ramipril suppressed the I/R-induced increase in oxidants and pro-inflammatory cytokines and the decrease in antioxidants (P < .001). Ramipril also attenuated I/R-induced histopathological damage in ovarian tissue (P < .05). CONCLUSION: Ramipril treatment may be a treatment strategy to protect ovarian tissue against oxidative and inflammatory damage of I/R.

RESUMO

Why most women can clear human papillomavirus (HPV) infections while others can develop permanent infections. The stimulation of immunotolerance of the immune system of the host by the persistent HPV infection may be the answer to this question. Interleukin-33 (IL-33) may play a role in the pathogenesis of HPV infection, this hypothesis was thought to be due to the rapid release of IL-33 from damaged cells following tissue damage, necrosis, and activation of the inflammasome. Thus, in this study, the role of IL-33/suppressor of tumorigenicity 2 (ST2) was emphasized in HPV positive and HPV negative cervical tissues. A total of 80 were assessed. The reduced levels of IL-33 and ST2 are associated with cervical HPV infections. There was a statistically significant 42% positive correlation between IL-33 and ST2 in the HPV-positive group. Surprisingly, our data showed no significant difference between the expression levels of IL-33 or ST2 and working status, type of delivery, pre- and post-operative pathology, cigarette, educational status, locality, birth control method, gynecological, and colposcopic findings. We found that as a result of our study; low IL-33 and ST2 levels were associated with HPV infections.

RESUMO

AIM OF THE STUDY: Fallopian tube cancer is very rare in the literature and so there are not enough data about the therapeutic approaches. The approaches are generally determined in accordance with the data obtained from ovarian cancer. Many prognostic factors have been investigated in an effort to better estimate patient outcome. Stage, age, and residual tumor after surgery are consistently important prognostic factors. In this study, we aimed to evaluate the prognostic factors and survival rates of primary fallopian tube cancer (PFTC), which is rare among gynecological cancers. MATERIAL AND METHODS: Thirty-eight patients with a diagnosis of PFTC were identified through the gynecologic oncology service database of our Research and Training Hospital in the period 1995-2013. Clinicopathological and surgical data were collected. All patients were evaluated for survival and disease-free survival between the dates specified. RESULTS: A significant relationship and correlation was found between optimal surgery and life expectancy. Better results were obtained in patients treated with optimal surgery. The survival probability was found to be higher in patients with lower CA-125 levels and serous histologic type adenocarcinoma. CONCLUSIONS: Stage is one of the factors affecting the survival probability. We determined that the pathological type of tumor, the diameter of residual tumor remaining after surgery, tumor grade, preoperative CA-125 levels and presence of ascites affect the survival probability.

RESUMO

The effect of rutin on ovarian ischemia-reperfusion (I/R) injury was investigated in this experimental study. Eighteen Wistar albino female rats were divided into three groups as follows: I/R group (IRG; n = 6), 50 mg/kg rutin + I/R group (RG; n = 6), and a healthy control group scheduled for a sham operation (SG; n = 6). 2 h of ischemia and following 2 h of reperfusion were created in the IRG and RG by using a torsion model involving atraumatic vascular clips. Rutin, a flavonoid glycoside, was injected intraperitoneally at the dose of 50 mg/kg to RG group 1 h before reperfusion. Then, rats were euthanized and their ovaries were removed for biochemical and histopathological examination and also assessment of the gene expressions. IRG group had a significant increase in malondialdehyde (MDA) levels, in the expressions of tumor necrosis factor alpha (TNF-α) and interleukin 1 beta (IL-1ß), and also in the activity of cyclooxygenase 2 (COX-2) unlike the significant decrease in total glutathione (tGSH) levels and the activity of COX-1 when compared to the SG group. However, rutin significantly decreased MDA levels, the expressions of TNF-α and IL-1ß, and also the activity of COX-2 while it increased significantly tGSH levels and the activity of COX-1 in the RG group in comparison with the IRG group. Rutin ameliorated the I/R-induced ovarian injury in rats via its possible antioxidative and anti-inflammatory effects.

RESUMO

AIM OF THE STUDY: The present study aims to estimate the prevalence and distribution of HPV genotypes and identify related risk factors among Turkish women. MATERIAL AND METHODS: 11 624 Turkish women attending our gynaecological clinic and expressing a desire for access to cervical cancer screening were assessed during the years 2014-2016. Cervical specimens were collected and transported using the HC2 HPV DNA Collection Device (consisting of a cervical brush and digene Specimen Transport Medium). RESULTS: Among these 11 624 individuals, positive HPV test results were obtained for 325 (2.79%), and negative results were observed for 11 299 (97.2%). The vast majority of patients were between the 3rd and 5th decades and the mean age of the patients was 44 ±9.12 (range 27-66). Among the HPV-positive women, 205 were positive for a single HPV type (205/325 = 63.1% of HPV infections; 205/11624 = 1.76% of all samples) and 120 were positive for multiple types (120/325 = 36.9% of HPV infections; 120/11624 = 1.03% of all samples). The four most prevalent high-risk types were HPV 16, 31, 51 and 52, with frequencies of 11.25%, 7.83%, 6.06% and 3.16%, respectively. CONCLUSIONS: There appears to be geographic variation in the distribution of HPV genotypes. In this study, the four most prevalent high-risk types were HPV 16, 31, 51 and 52, with frequencies of 11.25%, 7.83%, 6.06% and 3.16%, respectively.

RESUMO

OBJECTIVES: The aim of this paper is to determine the oxidative-antioxidative status and levels of soluble interleukin-2 recep-tor (sIL-2R) in serum of patients with different types of HPV infections and to compare it with patients who are negative for HPV. MATERIAL AND METHODS: A total of 80 women were divided into three groups as follows: Group 1 consisted of 25 women who were positive for HPV types 16 or 18; Group 2 consisted of 25 women who were positive for other types of HPV includ-ing type 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 or 68; Group 3 consisted of 30 patients who were negative for HPV as a control group. Serum sIL-2R and plasma oxidative stress index (OSI) were analyzed. RESULTS: Serum sIL-2R levels were significantly higher in group 1 compared to group 2 and 3. OSI was found significantly increased in groups 1 and 2 compared to group 3. Also, we found a weak positive correlation between IL-2R and OSI. CONCLUSION: sIL-2R and oxidative stress may have a role in HPV infection, especially in case of high-risk types.

RESUMO

OBJECTIVES: Appendicitis is the most common condition leading to an intraabdominal operation for a non obstetric problem in pregnancy and diagnosis of appendicitis is complicated by the physiologic and anatomic changes that occur during pregnancy. Although a surgical procedure carries the risk of fetal loss or preterm delivery, delay in diagnosis also increases the risk of complications in both mother and fetus. In this report we present our experience and analyze clinical characteristic and the pregnancy outcomes of appendicitis diagnosed incidentally during cesarean in the third trimester. MATERIAL AND METHODS: The study population consisted of 23 pregnant women who were diagnosed incidentally with appendicitis during cesarean at Erzincan University Hospital between 2015 and 2016. RESULTS: Appendectomy was performed on 23 patients during a caesarean section performed for any reason. The mean dia-meter of appendix was 7.82 ± 1.85 mm. The mean operation time was 67.39 ± 18.94 SD and antibiotic therapy was given to all patients. Postoperative complications were noted in 4 (17.4%) patients. Wound infection was seen in 4 (17.4%) patients, the other 19 patients revealed no postoperative complications. The mean of APGAR score of newborns in the postoperative period was 8.26 ± 0.86 SD and no complications were observed in both mothers and newborns. Histopathology of the specimen confirmed acute appendicitis in 23 (100%) cases. CONCLUSIONS: Acute appendicitis is a challenging diagnosis in the pregnant patient; however, early surgical intervention should be performed with any suspicion. The type of surgery depends on the surgeon's preference and experience.

RESUMO

Interleukin-33 (IL-33) is a novel cytokine involved in diabetes mellitus (DM) but its role in diabetic ovarian injury is unknown. As IL-33 is modulated by apoptosis, we aimed at investigating the effect of diabetes on ovaries in terms of evaluating apoptosis and IL-33 in a rat model. In this prospective experimental study, 16 female, nonpregnant Sprague-Dawley albino rats (12 weeks, 220-240 g) were randomly divided into two groups. Group 1 included eight healthy nondiabetic rats as controls and group 2 included eight rats in which diabetes was induced by intraperitoneal (i.p) injection of streptozotocin (STZ). After overt DM occurred (blood glucose >400 mgr/dl), all animals were euthanized and blood samples were collected by cardiac puncture for biochemical analysis. Bilateral oophorectomy was performed for histopathological examination. Serum levels of IL-33 and ovarian IL-33 and caspase-3 immunoexpressions were assessed. Immunoexpressions of caspase-3 and IL-33 were significantly higher in ovarian stromal cells of the diabetic rats compared to the controls. Also, in diabetic group, serum IL33 levels were significantly higher than the control group. In conclusion, increased IL-33 was observed both in serum and ovaries of STZ-induced diabetic rats as well as increased apoptosis in these diabetic rats. IL-33 may contribute to the apoptosis in diabetic ovarian injury.

RESUMO

OBJECTIVES: Our study aimed to determine the epidemiological characteristics and diagnostic and treatment protocols of primary vaginal carcinoma. Also, we compared the clinical and pathological features of primary vaginal carcinoma which intersect with cervical and vulvar carcinomas. MATERIAL AND METHODS: Sixteen patients with primary vaginal carcinoma, admitted to the Department of Gynecologic Oncology, Izmir Tepecik Training and Research Hospital between January 1983 and December 2012, were evaluated retrospectively. FIGO (International Federation of Gynecology and Obstetrics) Surgical staging was performed. The SPSS (Statistical Package for Social Sciences) program was used for statistical analyses. RESULTS: The histological distribution of the 16 patients with primary vaginal carcinoma was as follows: 9 patients (56.3%) with squamous cell carcinoma (SCC), 5 (31.3%) with rhabdomyosarcoma, and 2 (12.5%) with adenocarcinoma. CONCLUSION: The stage of the disease was found the be the main factor affecting the survival.

RESUMO

OBJECTIVES: To determine the short-term effects of adjuvant or primary curative radiotherapy (RT) on the urinary system in women with gynecologic cancer. MATERIAL AND METHODS: This is a prospective, concurrent cohort study including 55 patients with gynecologic cancer who were divided into three groups. Group 1 included 10 patients who were administered adjuvant RT following a radical hysterectomy (RH); Group 2 included 36 patients who were administered adjuvant RT following a type 1 hysterectomy and Group 3 included 9 patients who were administered primary curative RT. Urogynecologic assessments were carried out on patients before and six months after the treatment. RESULTS: Compared to pretreatment, no significant differences were observed in any of the three groups after treatment in terms of incontinence, first urge to urinate, normal urge to urinate, severe urge to urinate and changes in residual urine volumes. There was a significant decrease in maximal vesical pressure after treatment in Group 1 and Group 3. The maxi-mum detrusor pressure decreased significantly in Group 1. The post-treatment decline in bladder capacity in Group 1 and Group 2 was also significant. CONCLUSIONS: RH and pelvic RT cause lower urinary system dysfunction. Especially patients who receive primary curative RT and patients who are administered RT after RH, where more pelvic denervation occurs, are at higher risk due to high doses of RT.

RESUMO

OBJECTIVES: We aimed to evaluate and compare the clinical and pathological features, diagnosis, treatment, and prognosis of uterine papillary serous carcinoma (UPSC) and clear-cell carcinoma (CC). MATERIAL AND METHODS: Thirty-four patients who were operated on for UPSC and CC carcinoma at the Izmir Tepecik Research and Teaching Hospital, between January 1983 and December 2014, were included. Patients were evaluated for the following factors: age, gravidity, parity, preoperative CA-125, tumor size, myometrial and lymphovascular invasion, lymph node tumor metastasis, presence of atypical cells in peritoneal cytology, pathology results, operation types, whether or not they received postoperative adjuvant therapy, prognosis, and death rate. RESULTS: The stage of the disease was the main factor affecting disease-free and the overall survival. Cisplatin-based chemotherapy was partially effective in patients with postoperative recurrence, while postoperative adjuvant radiotherapy proved to be more effective in preventing relapse. CONCLUSION: The studied parameters generally were concordant with the literature but, due to the relatively small sample size, more comprehensive and multicenter studies are needed to generate valid results.

RESUMO

AIM: To investigate the effect of Kineret® on ischemia reperfusion (IR) injury in rat ovaries. METHODS: Rats were divided into four groups: ovarian IR (IRG); 50 mg/kg Kineret® + ovarian IR (KIR-50); 100 mg/kg Kineret® + ovarian IR (KIR-100); and sham operation (SOC). KIR-50 (n = 10) and KIR-100 (n = 10) groups received an intraperitoneal injection of Kineret® at doses of 50 and 100 mg/kg, respectively. IRG and SOC (n = 10) rat groups were given distilled water as solvent using the same method. The results were compared between the groups. RESULTS: In rats in which IR occurred, oxidant parameters, such as malondialdehyde (MDA) and myeloperoxidase (MPO), were increased, the level of proinflammatory interleukin 1 beta (IL-1ß) was elevated and total glutathione (tGSH) as an antioxidant was decreased in the ovarian tissues. Administration of Kineret® at a dose of 100 mg/kg inhibited the increase of MDA, MOP and IL-1ß and a decrease in tGSH caused by IR more significantly than administration of Kineret® at a dose of 50 mg/kg. In addition, 100 mg/kg Kineret® significantly decreased severe hemorrhage, degeneration and inflammatory signs in the follicular cells, caused by IR. Kineret® at 100 mg/kg markedly ameliorated increased apoptosis in ovarian tissue with IR more significantly than 50 mg/kg kineret. CONCLUSION: Our findings indicate that Kineret® might be useful in clinical practice for the treatment of damage that may occur as a result of ovarian torsion.

RESUMO

We aimed to evaluate the effect of melatonin on oxidative stress and ovarian injury in rats. Twenty-four Sprague-Dawley albino rats were divided into three groups: Group 1 as nondiabetic healthy controls (n = 8), group 2 as nontreated diabetic rats (n = 8) and group 3 as melatonin-treated diabetic rats (n = 8). After overt diabetes was produced by intraperitoneal injection of streptozosin, 20 mg/kg/day of melatonin was given intraperitoneally to group 3 for a week. NF-kB and caspase-3 immunoexpressions, lipid peroxidation, the activities of antioxidative enzymes, total oxidant capacity and total antioxidant capacity were assessed. Immunoexpressions of NF-kB and caspase-3 were significantly lower in group 3 than group 2. There was a significant decrease in superoxide dismutase activity in group 2 than group 1 and a significant increase in group 3 compared with group 2. We observed a nonsignificant decrease in catalase activity between group 1 and group 2 and a nonsignificant increase between group 2 and group 3. There was a nonsignificant increase in the plasma level of total oxidant status in group 2 than group 1, but a significant decrease was observed in group 3 compared to group 2. Total antioxidant status was significantly lower in group 2 compared with group 1 and group 3. In conclusion, melatonin ameliorates the negative effects of oxidative stress on DM-related ovarian injury.

RESUMO

OBJECTIVE: To investigate the effect of cigarette smoking on bone mineral density (BMD) in postmenopausal Turkish women. STUDY DESIGN: A total of 175 postmenopausal Turkish women admitted to Tepecik Training and Research Hospital for a routine menopausal checkup were included in this study. All participants completed a questionnaire regarding their age, educational status, parity, number of abortus, time since menopause, caffeine intake, tobacco use, alcohol consumption, history of a previous fracture related to trauma, and taking any medication for menopause and osteoporosis. Of all subjects, 23.3% (n = 39) were smokers and 77.7% (n = 136) were nonsmokers. T-scores and Z-scores of vertebra and femur neck were assessed using dual energy X-ray absorptiometry (DXA). For analyzing the results, Student t-test, one-way ANOVA, Mann-Whitney U test, Pearson correlation, and Kruskal-Wallis test were performed. RESULTS: Femur T-scores (- 0.78 ± 1.07 vs. - 0.32 ± 1.56) and vertebra T-scores (- 2.26 ± 1.23 vs. - 1.82 ± 1.04) were significantly lower in smoking women than nonsmoking women (p < 0.05). However, there were no significant difference between duration of smoking, number of cigarettes consumed per day, and BMD (p > 0.05) CONCLUSION: Cigarette smoking is one of the modifiable risk factors influencing bone density in postmenopausal Turkish women. "Cessation of cigarette" should be recommended for lifestyle modifications to prevent postmenopausal osteoporosis.

RESUMO

OBJECTIVE: The study aims to investigate the effects of diabetes mellitus (DM) on ovarian injury and reserve in a rat model. STUDY DESIGN: In this prospective experimental study, 16 female Sprague-Dawley albino rats (12 weeks, 220-240 g) were randomly divided into 2 groups. Group 1 included 8 normal healthy rats as controls. No drug was administered to the controls. Group 2 included the other 8 rats in which diabetes was induced by intraperitoneal injections of streptozotocin (STZ). After overt DM occurred (blood glucose >250 mg/dl), all the animals were euthanized and blood samples were collected by cardiac puncture for biochemical analysis. Bilateral oophorectomy was performed for histopathological examination. Immunoexpressions of nuclear factor-kappa B (NF-kB) and caspase-3 as well as anti-Müllerian hormone (AMH) levels were assessed. Values were analyzed by t test. RESULTS: Immunoexpressions of NF-kB and caspase-3 were significantly higher in non-treated diabetic rats than in the control group (p = 0.011 and p = 0.010, respectively). In healthy control group, AMH levels (3.22 ± 0.58 ng/ml) were significantly higher than in the non-treated diabetic group (1.41 ± 0.25 ng/dl; p = 0.024). CONCLUSION: Hyperglycemia causes severe ovarian injury via NF-kB pathway and caspase-3 apoptotic pathway, leading to the decrease in ovarian reserve in STZ-induced diabetic rats.

RESUMO

PURPOSE: To analyze treatment modalities and prognostic factors in patients with Stage I-II endometrial stromal sarcoma (ESS). MATERIALS AND METHODS: Twenty four patients (nineteen with low-grade ESS [LGESS] and five with high-grade ESS [HGESS]) were assessed retrospectively in terms of general characteristics, prognostic factors, treatment methods and survival. RESULTS: Twenty patients were at Stage I and three were at Stage II. The stage of one patient could not be determined. With respect to age and comorbidity, no statistically significant difference was found among disease-free survival (DFS) (p=0.990; p=0.995). However, DFS was significantly shorter in Stage II than Stage I patients (p=0.002). It was also significantly shorter in HGESS patients than in LGESS patients (p=0.000). There was no statistically significant differences among the overall survival (OVS) times of patients with respect to age at diagnosis and comorbid disease (p=0.905; p=0.979) but OVS was significantly shorter in patients with HGESS (p=0.00) and Stage II disease (p=0.001). No statistically significant difference was found with respect to OVS between patients who received radiotherapy (RT) and those who did not receive RT (p=0.055). It was not statistically possible to include other treatment modalities in the analysis because of the small sample size. CONCLUSIONS: Grade and stage of a tumour were found to be the most important prognostic factors. It was not possible to determine the optimal surgical method and the effect of adjuvant treatment since the number of cases was insufficient.

RESUMO

OBJECTIVE: To review 20 years of experience of the removal of intra-abdominal intrauterine devices (IUDs) and to compare the surgical methods used. METHODS: In a retrospective study, charts dating from between September 1, 1992, and August 31, 2012, were reviewed. Patients were eligible for inclusion when they had an IUD surgically removed by minilaparotomy or laparoscopy at a tertiary referral center in Izmir, Turkey. RESULTS: Among the 36 eligible women, 18 (50%) had undergone laparoscopy and 18 (50%) had undergone minilaparotomy. Mean operation length was 55.3±6.3 minutes in the laparoscopy group and 29.1±4.2 minutes in the minilaparotomy group (P=0.008). Conversion to full laparotomy was necessary in 4 (22%) women in the laparoscopy group and 1 (6%) in the minilaparotomy group (P=0.02). Perioperative complications were observed in 5 (14%) women, with no difference in frequency between groups (P=0.09). Total cost of medical/surgical procedures was US$436.4±35.4 for the laparoscopy group and $323.4±21.3 for the minilaparotomy group (P=0.04). CONCLUSION: Minilaparotomy seems to be an important alternative to laparoscopy for the removal of intra-abdominal IUDs. This procedure should be an integral part of gynecologic surgical training.

RESUMO

BACKGROUND/AIMS: Preeclampsia is a pregnancy-specific disease with the increased risk of maternal morbidity and mortality. It is characterised by placental vascular dysfunction. Despite the numerous studies on preeclampsia, studies evaluating proliferation of villous trophoblasts in preeclamptic placentas are limited. Ki67 is a proliferation marker that expresses in the nuclei of proliferating cells. In this study, we examined the proliferation of villous trophoblasts in placentas of preeclamptic patients by using Ki67 and compared it with placentas of normal pregnant patients. MATERIAL AND METHODS: The current study is a prospective one, including 15 placentas from preeclamptic patients and 14 placentas from normal pregnancies as controls. For detection of proliferation in villous trophoblasts, Ki67 was used. RESULTS: The Ki67 index was 11.48±1.67% in normal patients and 15.53±2.28% in preeclamptic patients. There was a difference in Ki67 index between the two groups (p < 0.001). CONCLUSION: Our results support the opinion that trophoblasts undergo regeneration hyperplasia as a result of injuries arising on the villous surface in preeclampsia. Proliferation of trophoblasts may contribute the development of preeclampsia.

RESUMO

BACKGROUND: Giant retroperitoneal uterine leiomyomas are uncommon. Degenerative changes of a leiomyoma may lead to unusual presentation resulting in misdiagnosis preoperatively. The final diagnosis can be made either intraoperatively or histologically. CASE: We report a 45-year-old multiparous women presented with abdominal distension and fatigue for six months. Abdominopelvic Sonography and computed tomography showed a large cystic mass that filled the pelvis and abdomen. With the preoperative diagnosis of a malignant tumor, a laparotomy was planned. Intraoperatively, a cystic mass originated from the uterus near the left side of the broad ligament extending to the retroperitoneal space was observed. Total hysterectomy and bilateral salphingo-oopherectomy was administered. The histology revealed a leiomyoma with cystic degeneration. CONCLUSION: Retroperitoneal leiomyomas should be kept in mind in the diferrential diagnosis of a giant cystic mass in abdomen.

RESUMO

Echinococcosis, which is caused by echinococcus granulosus, is also known as cystic hydatid disease, unilocular echinococcosis or cystic echinococcosis. Cystic echinococcosis is an alarming public health problem in some countries. Although the liver and lung are the organs involved most commonly by the disease, it may appear rarely in other tissues as a primary disease. Here, we present a 66-year-old patient who is invoved in farm work work. A Uterine multiseptate hydatid cyst was found on radiological investigations and the patient underwent surgery. A total hysterectomy was carried out. There were no postoperative complications.
