RESUMO
OBJECTIVE: The objectives of this study were to examine demographic and clinicopathologic characteristics and to determine the effects of primary surgery, surgical staging and the extensiveness of staging. METHODS: In a retrospective Turkish multicenter study, 539 patients, from 14 institutions, with borderline ovarian tumors were investigated. Some of the demographic, clinical and surgical characteristics of the cases were evaluated. The effects of type of surgery, surgical staging; complete or incomplete staging on survival rates were calculated by using Kaplan-Meier method. RESULTS: The median age at diagnosis was 40 years (range 15-84) and 71.1% of patients were premenopausal. The most common histologic types were serous and mucinous. Majority of the staged cases were in Stage IA (73.5%). 242 patients underwent conservative surgery. Recurrence rates were significantly higher in conservative surgery group (8.3% vs. 3%). Of all patients in this study, 294 (54.5%) have undergone surgical staging procedures. Of the patients who underwent surgical staging, 228 (77.6%) had comprehensive staging including lymphadenectomy. Appendectomy was performed on 204 (37.8%) of the patients. The median follow-up time was 36 months (range 1-120 months). Five-year survival rate was 100% and median survival time was 120 months. Surgical staging, lymph node sampling or dissection and appendectomy didn't cause any difference on survival. CONCLUSION: Comprehensive surgical staging, lymph node sampling or dissection and appendectomy are not beneficial in borderline ovarian tumors surgical management.

OBJECTIVE: To determine whether vaginal hysterectomy can be performed in patients with benign gynecologic diseases regardless of uterine size, uterine mobility and previous pelvic surgery and to compare with abdominal hysterectomy. STUDY DESIGN: Between 2003 and 2008, we compared 47 vaginal hysterectomies (VH) with 61 abdominal hysterectomies (AH). We excluded from the study the clinical conditions that mandate abdominal exploration and standard indications for VH such as uterovaginal prolapse. Large, immobile uterus and previous pelvic surgery were not accepted as a contraindication for VH. Demographic characteristics, primary diagnosis, uterine weight, operation time, intraoperative blood loss, complications, and hospital stay and cost in both groups were compared. RESULTS: Groups were similar with respect to demographic features and primary indications. Mean uterine weight and mean operation time were similar in VH and AH groups (258.0 g vs 293.9 g and 93.7 min vs 101.4 min, respectively). Oopherectomy was performed in 44.7% of VH and in 83.6% of AH. Colporrhaphies and/or anti-incontinence surgery were performed in 15 patients in the VH group (31.9%). The intraoperative blood loss was lower in the VH group than the AH group (245.0 mL vs 408.6 mL, P < 0.001). Perioperative complications were increased with AHs. The mean hospital stay and operation cost in the VH group were significantly less than the AH group (P < 0.001). CONCLUSION: This study indicates that vaginal hysterectomy could be performed with less morbidity in patients with benign gynecologic diseases even in large, immobile uterus and previous pelvic surgery.

Objective: This study aimed to investigate how gynecologic oncologists modified their patient management during Coronavirus disease-2019 (COVID-19) in Turkey. Material and Methods: An online survey was sent to gynecologic oncology specialists and fellows in Turkey. It included management questions about strategies for newly diagnosed or recurrent endometrial, cervical, ovarian and vulvar cancer during the pandemic. Participants were asked if treatment of these cancers can be delayed or not and, if yes, the duration of delay. Results: 32.9% of surgeons prescribed oral or intrauterine progesterone for early stage, low-grade endometrial cancer. Conversely, 65.7% and 45.7% of the most surgeons did not change their management for early stage high-grade and advanced stage endometrial cancers respectively, as they perform surgery. 58% and 67.1% of the surgeons continued to prefer standard surgical treatment for microinvasive and early stage cervical cancers, respectively. Radiotherapy was preferred administered with hypofractionated doses for locally advanced cervical cancer (57.1%). While 67.1% of surgeons operated early stage ovarian cancer patients, 50% administered neoadjuvant chemotherapy (NACT) to all advanced stage ovarian cancers and 50% administered more cycles of NACT in preference to interval debulking surgery. 93.7% of the surgeons responded that treatment should not be delayed beyond eight weeks. Conclusion: Most Turkish gynecologic oncologists modified their management of gynecologic cancers due to the COVID-19 pandemic. While chemotherapy was preferred for ovarian cancer, postponement of the surgery, with or without non-surgical options, was considered for early stage, low-grade endometrial cancer. Treatment of gynecologic cancers should be decided on a case by case basis, taking into account local COVID-19 infection rates and availability of health facilities. Prognosis is also an important consideration if delay is contemplated. Standard treatment and normal time-frames should be used if possible. If not, a postponement for a maximum of eight weeks or referral to another center were acceptable alternatives.
RESUMO
BACKGROUND: Cervical cancer is one of the most frequent malignancies in women. Micronucleus (MN) testing has gained popularity as a biomarker in early diagnosis of many types of cancer. AIMS: This study aims to investigate the role of MN testing on early detection of cervical cancer and the effect of boron exposure on cervical cells. SETTINGS AND DESIGN: The study population comprised women who were diagnosed to be human papillomavirus (HPV)-positive and had atypical squamous cells of undetermined significance (ASCUS) as cervical cytology in a cervical screening project. A total of 15 HPV-positive and 36 ASCUS patients were identified. Randomly selected 20 women were selected from boron-rich region (n = 10) and nonboron region (n = 10). MATERIALS AND METHODS: Cervical swab specimens were dyed using Papanicolaou (PAP) and May-Grünwalds-Giemsa (MGG) techniques, and MN count in 1000 cells was performed. The results were statistically evaluated. STATISTICAL ANALYSIS USED: Data were analyzed using Statistical Package for the Social Sciences (SPSS) version 13. Quantitative data were presented as mean ± standard deviation. MN test scoring was compared using Mann-Whitney U-test. RESULTS: Boron content of urine was measured to be 3.02 ± 1.45 and 0.98 ± 0.42 mg/day in boron-rich and nonboron regions, respectively. When MN counts were compared according to PAP and MGG staining in HPV- and ASCUS-positive women, there was statistically no significant difference (P > 0.05). Disregarding regions, HPV/control and HPV/ASCUS cases stained with PAP and MGG had statistically significant difference in MN count (P < 0.05). CONCLUSION: These findings suggest that MGG and PAP staining gives similar results with regard to MN count. On the other hand, it has been shown again that HPV induces MN and causes genomic instability.
RESUMO
AIM: To study the efficacy of pirfenidone for prevention of postoperative adhesion formation in an adhesion rat model. MATERIALS AND METHODS: Eighteen female Wistar rats were subjected to right-sided parietal peritoneum and right uterine horn adhesion model. Rats were randomized into three groups: group 1 (control) (closure of midline abdominal incision without any agent administration), group 2 (closure of incision after intraperitoneal administration of pirfenidone), and group 3 (closure of incision and only oral administration of pirfenidone for 14 days). Relaparotomy was performed 14 days after the first surgery. Effect of pirfenidone on adhesion formation was assessed on light microscopy by scoring vascular proliferation, inflammation, fibrosis, and collagen formation in the scarred tissue. Effect of pirfenidone on inflammation was assessed by measurement of transforming growth factor-ß and interleukin-17 levels in scarred tissue. RESULTS: The degree of vascular proliferation (1.32 ± 0.39 versus 2.34 ± 0.46, p < 0.001), inflammation (1.60 ± 0.70 versus 2.60 ± 0.52, p < 0.01), and fibrosis (1.50 ± 0.53 versus 2.40 ± 0.52, p < 0.01) were less prominent in group 2 compared to group 1, respectively. Only vascular proliferation was found to be less prominent in group 3 compared to group 1 (1.60 ± 0.42 versus 2.34 ± 0.46, p < 0.01). Intraperitoneal and oral administration of pirfenidone reduced tissue levels of inflammatory markers (TGF-ß and IL-17) in parietal and visceral peritoneum compared to control group. Intraperitoneal administration of pirfenidone compared to oral administration was more effective in reducing tissue levels of inflammatory markers. CONCLUSION: Pirfenidone is an effective agent on the prevention of postoperative vascular proliferation, inflammation and fibrosis in scarred tissue particularly with intraperitoneal administration.

AIMS: To investigate clinicopathologic characteristics, therapeutic methods, and prognostic factors in women with synchronous primary endometrial and ovarian cancers (SEOCs). METHODS: A retrospective review of 2 cancer registry databases in Turkey was conducted to identify patients diagnosed with SEOCs between January 1995 and December 2012. Patients with recurrent, metastatic, and metachronously occurring tumors were excluded. Multivariate logistic regression models were used to identify prognostic predictors for progression-free survival (PFS) and overall survival (OS). RESULTS: The analysis included 63 women with SEOCs. Seventy-six percent of the patients had stage I endometrial cancer, and 60% of the patients had stage I ovarian cancer. Thirty-seven patients (58.7%) had endometrioid/endometrioid histology. Optimal cytoreduction was obtained in 47 (74.6%) patients. Recurrence developed in 17 patients (27%). Multivariate analysis confirmed lymphovascular space invasion (LVSI) as an independent poor prognostic factor for OS (odds ratio [OR] 3.1, p = 0.045), whereas early-stage disease and optimal cytoreduction were found to be independent good prognostic factors for both PFS (OR 12.85, p<0.001 and OR 4.58, p = 0.004, respectively) and OS (OR 7.31, p = 0.002 and OR 2.95, p = 0.028, respectively). The 3- and 5-year OS rates were 74% and 69%, respectively. CONCLUSIONS: Our study demonstrated that optimal cytoreduction, early-stage disease, and LVSI are the most significant factors affecting survival in women with SEOC.

Aim. Comparison of the rate of wound complications, pain, and patient satisfaction based on used subcuticular suture material. Methods. A total of 250 consecutive women undergoing primary and repeat cesarean section with low transverse incision were prospectively included. The primary outcome was wound complication rate including infection, dehiscence, hematoma, and hypertrophic scar formation within a 6-week period after operation. Secondary outcomes were skin closure time, the need for use of additional analgesic agent, pain score on numeric rating scale, cosmetic score, and patient scar satisfaction scale. Results. Absorbable polyglactin was used in 108 patients and nonabsorbable polypropylene was used in 142 patients. Wound complication rates were similar in primary and repeat cesarean groups based on the type of suture material. Skin closure time is longer in nonabsorbable suture material group in both primary and repeat cesarean groups. There was no difference between groups in terms of postoperative pain, need for additional analgesic use, late phase pain, and itching at the scar. Although the cosmetic results tended to be better in the nonabsorbable group in primary surgery patients, there was no significant difference in the visual satisfaction of the patients. Conclusions. Absorbable and nonabsorbable suture materials are comparable in cesarean section operation skin closure.
RESUMO
The aim of this study was to compare the tocolytic effect of a selective cyclooxygenase-2 inhibitor, DFU (5,5-dimethyl-3(3-fluorophenyl)-4-(4-methylsulphonyl)phenyl-2(5H)-furanone), indomethacin and nimesulide on myometrial strips isolated from rats in both lipopolysaccharide-induced preterm labour and term labour. We also compared the constrictor effects of DFU and indomethacin on the fetal ductus arteriosus. Myometrial strips were obtained from preterm and term labour Wistar albino rats and were mounted in organ baths for the recording of isometric tension. DFU, nimesulide and indomethacin significantly inhibited KCl-, oxytocin-, prostaglandin E(2)- and prostaglandin F(2 alpha)-stimulated contractions of myometrial strips isolated from rats in preterm and term labour. The E(max) value of indomethacin was significantly lower than those for DFU and nimesulide (P<0.05), with no change-log (10) EC(50) values. There was no significant difference between in -log (10) EC(50) and E(max) values of DFU and nimesulide for any of the tissues (P>0.05). In addition, there was no significant difference between -log (10) EC(50) and E(max) values for each of these three agents in myometrial tissues isolated from rats in preterm and term labour (P>0.05). Fetal ductus arteriosus was significantly constricted by DFU (10 or 100 mg/kg) in preterm and term rats, although DFU (10 or 100 mg/kg)-induced constriction ratios were significantly lower than those for indomethacin (P<0.05). These data demonstrate that DFU, a specific cyclooxygenase-2 inhibitor, could be considered as a new therapeutic agent for preterm labour. However, careful attention should be given to constriction of the fetal ductus arteriosus.

OBJECTIVES: To compare the anti-adhesion potential of 1% methylene blue (MB) solution and 2% N,O-carboxymethylchitosan (NOCC) gel in a rat uterine horn model. DESIGN: Experimental animal study. SETTING: University medical center. ANIMAL(S): Forty female Wistar albino rats randomized into four groups. INTERVENTION(S): We examined the effects of 1% MB solution and 2% NOCC gel to reduce the extent and severity of postoperative adhesions in a rat uterine horn model: no adjuvant therapy in control group, 2 mL of normal saline (NS) solution in NS group, 2 mL of 1% MB solution in MB group, and 2 mL of 2% NOCC gel in NOCC group was instilled onto uterine horns of the rats. MAIN OUTCOME MEASURE(S): Adhesions were scored according to their extent and severity. RESULT(S): The extent and severity scores of adhesions in MB and NOCC groups were significantly lower than those of control and NS groups. There was no statistically significant difference between the extent and severity scores of adhesions between MB and NOCC groups. CONCLUSION(S): These findings suggest that MB and 2% NOCC gel should be considered as an adjuvant in the prevention of postoperative intra-abdominal adhesions. Future experimental and clinical studies are required to find their optimal formulation and usage.

OBJECTIVE: The goal of this study is to evaluate the effect of glyceryl trinitrate (GTN) in the management of hypertension in women with preeclampsia, eclampsia, and HELLP syndrome. STUDY DESIGN: Fifty five women with preeclampsia, eclampsia, and HELLP syndrome administered GTN infusion for the management of hypertension were studied. Demographic, clinical, and perinatal outcome findings were collected for analyses. We recorded initial and maintenance doses of GTN, and duration of its use in prepartum and postpartum periods. We collected systolic and diastolic blood pressures (BPs) at admission and before the administration of GTN infusion. During the GTN infusion, we calculated average diastolic and systolic blood pressures 6 hours apart on the first day, 12 hours apart on the second day, and 24 hours apart on the third day. RESULTS: Of 55 women, 24 with severe preeclampsia, 16 with HELLP syndrome, and 15 with eclampsia were included in this study. In severe preeclampsia group, GTN infusion significantly reduced systolic and diastolic BPs beginning from the second quarter and third quarter, respectively, of first day (p < 0.05). In the HELLP syndrome group, GTN infusion significantly decreased systolic and diastolic blood pressures beginning from the third quarter and second quarter, respectively, of the first day (p < 0.05). In the eclampsia group, GTN infusion significantly reduced systolic and diastolic blood pressures beginning from the third quarter and first quarter, respectively, of the first day (p < 0.05). CONCLUSION: In women with severe preeclampsia, eclampsia, and HELLP syndrome, infusion of GTN can be used as an alternative agent to well-known drugs and causes no significant adverse effect to the mother and fetus.

OBJECTIVE: The effects of 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB), anthracene-9-carboxylate (9-AC) (chloride channel blockers) and zaprinast (an inhibitor of phosphodiesterase-5) on endothelin-1 (ET-1) induced contractions of pregnant rat myometrium were investigated in vitro. METHODS: Isolated myometrial strips were obtained from pregnant rats, and the strips were mounted in organ baths for recording of isometric tension (n=8). The effects of 10(-7) to 10(-4)M NPPB, 10(-7) to 10(-4)M 9-AC, and 10(-7) to 10(-4)M zaprinast on 10(-8)M ET-1-induced contractions of pregnant rat myometrial smooth muscle were recorded. RESULTS: NPPB and 9-AC increased the amplitude of ET-1-induced myometrial contractions, while decreasing the frequency, in a concentration-dependent manner. The amplitude of myometrial contractions were significantly increased by NPPB and 9-AC beginning from the concentration of 10(-6)M. The frequency of myometrial contractions were significantly decreased by NPPB and 9-AC beginning from the concentration of 10(-6)M. Zaprinast inhibited the amplitude and frequency of ET-1-induced myometrial contractions in a concentration-dependent manner. Zaprinast-induced decreases in amplitude and frequency of myometrial contractions reached statistical significance beginning from the concentrations of 10(-7)M and 10(-5)M, respectively. CONCLUSION: These data provide evidence that the ET-1-induced contractions of pregnant rat myometrial strips may be modulated by chloride channels. In addition, zaprinast effectively inhibited ET-1-induced contractions in pregnant rat myometrium.

OBJECTIVE: To compare the effects of 5,5-dimethyl-3-(3-fluorophenyl)-4-(4-methylsulphonyl) phenyl-2(5H)-furanone (DFU) and nimesulide, selective COX-2 inhibitors, on the amplitude and frequency of KCl-, oxytocin-, and PGF(2alpha)-stimulated contractions of isolated pregnant human myometrial strips. METHODS: Isolated myometrial strips were obtained from 20 pregnant women undergoing elective cesarean section. These strips were mounted in organ baths for recording of isometric tension. The effects of cumulative concentrations of nimesulide and DFU on KCl-, oxytocin-, and PGF(2alpha)-stimulated myometrial contractions were measured, and values for -log(10)EC(50) and mean maximal inhibition (E(max)) were compared. Nimesulide (10(-8) to 10(-4)M) and DFU (10(-8) to 10(-4)M) inhibited in a concentration-dependent manner the KCl-, oxytocin-, and PGF(2alpha)-stimulated contractions of myometrial strips, with a significant effect on the amplitude (10(-7) to 10(-4)M) and the frequency (10(-6) to 10(-4)M). RESULTS: The inhibitor effect of DFU was more potent than nimesulide on KCl-, oxytocin-, and PGF(2alpha)-stimulated myometrial contractions, however, the inhibitor effects of nimesulide and DFU was much greater on KCl-stimulated contractions than on oxytocin- and PGF(2alpha)-stimulated myometrial contractions (P < 0.05). There was no significant difference between E(max) values of nimesulide and DFU in all tissues (P > 0.05). CONCLUSION: DFU is a more potent inhibitor than nimesulide on KCl-, oxytocin-, and PGF(2alpha)-stimulated contractions of pregnant human myometrium. The inhibitor effects of nimesulide and DFU were predominantly on KCl-stimulated contractions.

BACKGROUND: Postsurgical adhesions can occur following virtually all types of surgery, resulting in serious clinical complications. Therefore, prevention of adhesions is an important goal of surgical practice. A rat uterine horn model was used to investigate the efficacy of N,O-carboxymethylchitosan (NOCC) and spermine NONOate (SPER/NO) alone and in combination in preventing adhesion formation. METHODS: Sixty Wistar albino rats underwent bilateral uterine horn injury with a unipolar cautery. Study groups were as follows: (i) control group, no adjuvant therapy; and those with adjuvant applied, (ii) normal saline group, 2 ml of normal saline was given; (iii) NOCC group, 2 ml of 2% NOCC gel was given; (iv) SPER/NO group, 2 ml of SPER/NO (0.5 mg/ml) was given, and (v) NOCC plus SPER/NO group, 2 ml of 2% NOCC gel including SPER/NO (0.5 mg/ml) was given. After 14 days, all animals were euthanatized, and a standard adhesion scoring system including extent and severity scores was applied by a blinded examiner. RESULTS: The extent score in NOCC plus SPER/NO group was significantly lower than those of control and normal saline groups (p < 0.05). The extent score in NOCC group was significantly lower than that of normal saline group (p < 0.05). The extent score in NOCC plus SPER/NO group was significantly lower than that of SPER/NO group (p < 0.05). The severity score was significantly lower in NOCC plus SPER/NO and NOCC groups than that of control group (p < 0.05). The severity score was significantly lower in NOCC plus SPER/NO group than that of SPER/NO group (p < 0.05). CONCLUSIONS: Postoperative administration of NOCC gel and SPER/NO alone and especially in combination to the site of peritoneal injury reduces the formation of adhesions in the rat uterine horn model.

BACKGROUND: To evaluate the incidence, diagnosis and management of GTN among 28 centers in Turkey. MATERIALS AND METHODS: A retrospective study was designed to include GTN patients attending 28 centers in the 10-year period between January 2003 and May 2013. Demographical characteristics of the patients, histopathological diagnosis, the International Federation of Gynecology and Obstetrics (FIGO) anatomical and prognostic scores, use of single-agent and multi-agent chemotherapy, surgical interventions and prognosis were evaluated. RESULTS: From 2003-2013, there were 1,173,235 deliveries and 456 GTN cases at the 28 centers. The incidence was calculated to be 0.38 per 1,000 deliveries. According to the evaluated data of 364 patients, the median age at diagnosis was 31 years (range, 15-59 years). A histopathological diagnosis was present for 45.1% of the patients, and invasive mole, choriocarcinoma and PSTTs were diagnosed in 22.3% (n=81), 18.1% (n=66) and 4.7% (n=17) of the patients, respectively. Regarding final prognosis, 352 (96.7%) of the patients had remission, and 7 (1.9%) had persistence, whereas the disease was mortal for 5 (1.4%) of the patients. CONCLUSIONS: Because of the differences between countries, it is important to provide national registration systems and special clinics for the accurate diagnosis and treatment of GTN.

Intermittent pelvic pain caused by ovarian cysts in adolescence may be due to torsion or partial torsion of the ovary. We present a case of 18-year old adolescent with symptomatic left ovarian torsion with calcifications demonstrated by pelvic MRI and ultrasonography prior to surgery. The pathologic investigation demonstrated dystrophic calcifications. We speculated that the pattern of the intermittent pain in the story of the patient and the dystrophic calcifications in pathologic investigation which is thought that it might have been potentially developed as a result of chronic hypoxia due to intermittent partial torsions over a period of two years.
RESUMO
OBJECTIVE: To analyze the results of fertility-sparing treatment of early-stage endometrial cancer (EC) in patients treated at Turkish gynecologic oncology centers, and to present a review of the literature. METHODS: Thirteen healthcare centers in Turkey were contacted to determine if they were eligible to participate in the study. Centers that were eligible and agreed to participate were sent a database form to record the demographic characteristics, clinicopathologic findings, and follow-up results for their EC patients. RESULTS: Eleven Turkish healthcare centers provided data on 43 EC patients. Mean duration of treatment was 5 months and mean follow-up was 49 months. In total, 35 (81.4%) patients were tumor free following primary progesterone therapy. Mean time from the end of progesterone therapy to pregnancy was 10.6 ± 4.3 months (range, 3-18 months). Two patients had tumor recurrence during follow-up. The pregnancy rate among the 31 women who actively sought pregnancy was 41.9% (n=13). CONCLUSION: Conservative management of early-stage EC in women of reproductive age using oral progestins was effective and did not compromise oncological outcome. Pregnancy in the study patients was achieved spontaneously and artificially.

OBJECTIVE: To investigate the effects of GnRH antagonist (GnRH-ant) and agonist (GnRH-a) in the prevention of postoperative pelvic adhesions by a visual scoring system and immunohistochemical methods in a rat uterine horn model. DESIGN: Controlled experimental animal study. SETTING: Animal laboratory at an academic research environment. ANIMAL(S): Twenty-one Wistar albino rats. INTERVENTION(S): Rats were randomized into three groups. One week before the operation the rats received either GnRH-ant or GnRH-a or saline solution; they then underwent surgical laparotomy, and both uterine horns were traumatized by a scalpel. Three weeks later, all rats were sacrificed and extension and severity of the adhesions in each group were scored by a visual scoring system. Adhesion tissues were evaluated immunohistochemically for vitronectin and u-PAR. MAIN OUTCOME MEASURE(S): Scores of extend and severity of adhesions and staining of vitronectin and u-PAR. RESULT(S): The extent of adhesion scores were 1.85 ± 0.86, 0.78 ± 1.05, and 0.42 ± 0.64, and the severity of adhesion scores were 1.71 ± 0.91, 0.57 ± 0.85, 0.50 ± 0.75 for control, GnRH-ant, and GnRH-a groups, respectively. The extent and severity of adhesions were significantly lower in both GnRH-ant and GnRH-a groups when compared with the control group. Adhesion extent scores in the GnRH-a group were lower than in the GnRH-ant group, but this difference was not significant. vitronectin and u-PAR staining were significantly greater in both the GnRH-ant and GnRH-a groups than in the control group. CONCLUSION(S): GnRH-ant as well as GnRH-a reduced postoperative adhesion formation in a rat model. This finding was supported immunohistochemically by vitronectin and u-PAR staining.

INTRODUCTION: The purpose of this study was to compare the effects of different postmenopausal hormone therapy regimens, namely conjugated equine estrogens (CEE), CEE plus medroxyprogesterone acetate (MPA), tibolone, and raloxifene on cerebral blood flow and cognitive functions. METHODS: A total of 64 healthy postmenopausal women admitted to the Department of Obstetrics and Gynecology, Cumhuriyet University, Turkey were included in this study. Patients were divided into five groups with respect to the treatment protocols: CEE 0.625 mg/day (n=13); CEE 0.625 mg/day + MPA 2.5 mg/day (n=14); tibolone 2.5 mg/day (n=11); raloxifene 60 mg/day (n=9); and control (n=17). The CEE group included only women with surgical menopause. Those who were on hormonal therapy, who had previously used hormonal therapy, who had neurological disorders, or who did not accept the longterm follow-up were excluded from the study. Demographic and clinic characteristics were recorded. Before starting the therapy regimens, cerebral blood flow was evaluated by internal carotid artery and middle cerebral artery peak systolic velocity, and pulsatility index measurements via Doppler ultrasonography. Cognitive functions were evaluated by the Standardized Mini-Mental Test. The mean follow-up period was 10.9+/-2.4 months, ranging between 8 and 16 months. After the follow-up period, the cerebral blood flow, and cognitive function of each woman was re-evaluated. RESULTS: Demographic and clinical characteristics of the women were not significantly different between the study groups (P>0.05). There were no significant differences between the pretreatment and posttreatment values for cerebral blood flow indices and cognitive function scores in any of the study groups (P>0.05). CONCLUSION: Different postmenopausal hormone therapy regimens have not revealed any significant effects on either cerebral blood flow or cognitive function.

BACKGROUND: Heparin and low molecular weight heparin (LMWH) are used widely to improve the pregnancy outcome in women with thrombophilia, miscarriage, recurrent miscarriage and fetal death. This study was designed to investigate the effects of heparin and LMWHs, enoxaparin and tinzaparin, on E-cadherin and laminin expression in placental and decidual tissues in rat pregnancy. METHODS: Wistar albino female rats (n = 48) were randomly assigned to four study groups (normal saline, heparin, enoxaparin and tinzaparin) in the preconceptional period. Tissue sections of placenta and decidua were immunohistochemically examined for the expression of E-cadherin and laminin. RESULTS: E-cadherin placental staining score of heparin group was significantly lower and E-cadherin decidual staining score of heparin and enoxaparin groups were significantly lower than control group. There were no significant differences in placental and decidual laminin staining scores among the study groups. CONCLUSIONS: Heparin and enoxaparin can reduce E-cadherin expression but not laminin expression in rat pregnancy. They might modulate trophoblast invasion. We suggest that this is the possible underlying mechanism involving in improvement of trophoblast invasion by the use of heparin and LMWH in patients with the history of miscarriage.

BACKGROUND: Schwannoma is a well-defined, usually benign tumor arising from the Schwann cells in the nerve sheath. It can present in any location as a solitary mass; however, it is rarely found in the pelvis. CASE: We report a 40-year-old female patient with a pelvic mass, which revealed tubal schwannoma after complete resection of the mass and uterus by laparotomy. CONCLUSION: Schwannomas are thought to result from a proliferation of perineural cells. Although origin along the nerves of the retroperitoneal space is not uncommon, these tumors rarely present as pelvic masses.
