RESUMO

AIM: Endometriosis is a common, chronic benign gynecologic disease and distresses women in their reproductive age. Yet the pathogenesis of endometriosis is not clear, multifactorial mechanisms have been characterized for the initiation, progression, and regression of this disease. It has been suggested that immune cells in the lymphoid lineage play essential roles in accepting or rejecting the survival, implantation, and proliferation of endometrial and endometriotic cells and, dysfunction of B-lymphocytes (B-cells) are one of the major causes for the progression of endometriosis. In this study, we aimed to evaluate the potential therapeutic efficacy of Rituximab, an inhibitor for B-cells, for endometriosis in an experimental animal model. METHODS: Experimental endometriosis animal model has been utilized using mature female rats. Rats underwent surgery to initiate endometriosis on the abdominal wall. After confirming for endometriosis, rats were treated with either Rituximab or saline solution. After 14 days of treatment, implants were dissected, and evaluated for volumes and histological features. Anti-CD-20 antibody was used for immunohistochemistry scoring purposes. RESULTS: There is significant decrease in the volume of endometriotic implants after treatment with Rituximab (188.81 ± 149.42 vs 20.37 ± 13.08, p = 0.001). There are also significant differences for the B-cell count and fibrosis score between the control and treatment groups (3.08 ± 2.6 vs 1.56 ± 1.42., p = 0.043). CONCLUSION: In an experimental rat endometriosis model, we assessed Rituximab, an antibody for B-lymphocyte, as a candidate medical treatment for endometriosis. Additional studies are required to further evaluate the effects of Rituximab on the prevention of endometriosis.

RESUMO

Agents to reduce the gonadotoxic effects of chemotherapeutics are still under investigation. In this context, we aimed to investigate the protective effect of sildenafil against chemotherapeutic-induced gonadotoxicity in a rat model. A total of 62 female rats were divided into eight groups as control, sildenafil (1.4 mg/kg, orally), doxorubicin (3 mg/kg, i.p.), cisplatin (5 mg/kg, i.p.), cyclophosphamide (200 mg/kg, i.p.), doxorubicin+sildenafil, cisplatin+sildenafil, and cyclophosphamide+sildenafil (1.4 mg/kg orally sildenafil in addition to the same dose of chemotherapeutics). The groups were compared in terms of follicle count, ovarian size, and anti-müllerian hormone (AMH) levels. Use of sildenafil with cyclophosphamide was effective only in preserving primary follicle count (p = 0.026) and had no significant change in the secondary follicle count, ovarian size, or AMH level. Adding sildenafil to cisplatin had a significant protective effect on primary follicle count (p = 0.011), secondary follicle count (p = 0.009), and ovarian size (p = 0.001), but this effect could not be demonstrated at AMH level. Sildenafil was not effective on any parameter in the doxorubicin group. Sildenafil may be effective in reducing the gonadotoxicity associated with the use of cisplatin and cyclophosphamide.

RESUMO

RESEARCH QUESTION: Angiotensin-converting enzyme inhibition results in a significant reduction in plasma concentrations of plasminogen activator inhibitor-1 (PAI-1). What are the effects of lisinopril treatment on PAI-1 concentrations and the morphology and function of the ovaries in the letrozole-induced polycystic ovary syndrome (PCOS) rat model? DESIGN: This prospective randomized controlled animal study involved female Wistar albino rats. Twelve rats were assigned as controls (group I). In the study group (n = 48), letrozole (an aromatase inhibitor) was administered for PCOS modelling for 9 weeks. After confirming disrupted oestrous cycles, the study group was randomized into two groups: group II (n = 24; letrozole only) and group III (n = 24; letrozole + lisinopril 15 mg/kg per day). After 12 weeks, each group was divided randomly into two. Biochemical, histopathological and immunohistochemical analyses was performed in subgroups designated A, and fertilization rates were studied in subgroups designated B. RESULTS: Lisinopril treatment reduced the weight and area of the ovaries, the number and wall thickness of cystic follicles, and serum concentrations of LH and testosterone, relative to group II (P < 0.001). Circulating PAI-1 concentrations were significantly different among three groups (7.7 ± 0.9 ng/ml, 9.8 ± 0.7 ng/ml and 8.6 ± 0.7 ng/ml for groups IA, IIA and IIIA; P < 0.001). Pregnancy rates were 100%, 0% and 16.7% in groups IB, IIB and IIIB. CONCLUSIONS: In the letrozole-induced rodent PCOS model, lisinopril modifies the action of letrozole, possibly by inhibition of systemic and ovarian production of PAI-1. The use of PAI-1 inhibitors deserves further investigation in understanding the pathogenesis of PCOS.

RESUMO

The management of a caesarean scar pregnancy ranges from conservative medical therapy to surgical treatment. The aim of this study is to present our experience of caesarean scar ectopic pregnancies treated with different modalities and to develop a management algorithm. This retrospective clinical analysis included 21 caesarean scar pregnancies. The clinical data, ultrasonographic characteristics, b-human chorionic gonadotropin concentrations, the treatment options and complications were noted. One patient was managed expectantly, six patients were treated with D and C, seven patients were treated with systemic methotrexate, eight patients underwent a caesarean scar pregnancy removal with a laparoscopy, three patients were treated with a hysteroscopy. Three patients who recieved a methotrexate required additional treatment methods including a laparoscopy, hysteroscopy and D and C. Surgery was successful in all cases. An intra-abdominal haemorrhage from the vessels in the scar area occured in the patient managed expectantly, and a laparatomy and removal was performed. A systemic methotrexate, dilatation and curettage, hysteroscopic resection and laparoscopic resection are feasible methods for scar pregnancy treatment depending on the gestational age, ß-hCG level, the type of scar pregnancy and the clinical status of the patient. IMPACT STATEMENT What is already known on this subject? CSP has increased gradually parallel to the increased rates of CS worldwide. There is no treatment consensus on that rare entity. What do the results of this study add? We aimed to present our cases and to discuss a proposal algorithm with further studies. What are the implications of these findings for clinical practice and/or further research? Our cases and proposal algorithm could help to determine the treatment options for CSP.

RESUMO

AIM: To investigate association of kisspeptin levels in infertile women with different ovarian reserve patterns. MATERIALS AND METHODS: In this prospective cross-sectional study, 157 participants were recruited. The women were divided into three groups: (i) adequate ovarian reserve (AOR) (n = 57), (ii) high ovarian reserve (PCOS) (n = 60), (iii) diminished ovarian reserve (DOR) (n = 40). Weight, height, waist circumference (WC), hip circumference (HC), body mass index (BMI), waist/hip ratio (WHR) were measured. The blood samples were analyzed for estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), total testosterone (TT), 17-hydroxy progesterone (17OHP), dehydroepiandrosterone sulfate (DHEAS), antimullerian hormone (AMH), kisspeptin measurements. RESULTS: FSH concentration was higher and AMH concentration was lower in DOR group (p < .001, p < .001, respectively). The mean LH, TT and DHEAS levels were higher in PCOS group (p = .001, p < .00 and p = .003, respectively). The 17OHP level did not differ among the groups (p = .15). Women with PCOS possessed the highest kisspeptin level (p = .01). The kisspeptin level was negatively correlated with FSH level (r = -0.18, p = .02) and positively correlated with TT and DHEAS levels (r = 0.17, p = .02 and r = 0.23, p = .003, respectively). CONCLUSIONS: Women with PCOS had increased serum kisspeptin levels. Kisspeptin concentrations were negatively correlated with serum FSH and positively correlated with serum TT and DHEAS levels.

RESUMO

The aim of this study was to investigate the effects of caffeic acid phenethyl ester (CAPE) as a prophylactic agent on ischemia/reperfusion (I/R) injury in the rat ovary. A total of 28 Wistar rats were divided into 4 equal groups: (I) sham, (II) ischemia, (III) ischemia + reperfusion, and (IV) IR + CAPE. In groups I and II, ovary torsion was not performed and no drug was administered. In group III, 1 hour of ischemia and 2 hours of reperfusion were performed and no drug was given. Ovarian tissue concentrations of malondialdehyde were significantly higher in the torsion and detorsion groups compared with the sham and Cape groups (P<0.005). The detorsion group showed preantral ovarian follicles and luteal folicules around the blood vessels and positive expression of CD34. In the CAPE group the stromal vascular endothelium with weak expression of CD34 was detected in small areas, and the ovarian follicles and the corpus luteum showed negative expression of CD34. In the study, Biochemical and histopathological results of CAPE treatment was considered to torsion-detorsioned the model showed a protective effect against tissue damage.


El objetivo de este trabajo consistió en investigar los efectos del éster fenetílico del ácido cafeico (EFAC) como agente profiláctico en la lesión por isquemia/reperfusión (I / R) en el ovario de rata. Un total de 28 ratas Wistar se dividieron en 4 grupos iguales: (I) control, (II) isquemia, (III) isquemia + reperfusión, y (IV) IR + EFAC. En los grupos I y II, no se realizó torsión ovárica y no se administró ningún fármaco. En el grupo III, se provocó una hora de isquemia, dos horas de reperfusión y no se administró ningún fármaco. Las concentraciones de malondialdehído en los tejidos ováricos fueron significativamente mayores en los grupos de torsión y de destorsión, en comparación con los grupos sham y de EFAC (P <0,005). El grupo de destorsión mostró folículos ováricos preantrales y folículos lúteos alrededor de los vasos sanguíneos y expresión positiva de CD34. En el grupo EFAC el endotelio vascular estromal con expresión débil de CD34 se detectó en áreas pequeñas, y los folículos ováricos y el cuerpo lúteo mostraron expresión negativa de CD34. En el estudio, fueron considerados los resultados bioquímicos e histopatológicos del tratamiento EFAC en relación a la torsión-destorsión, desarrollando un modelo que mostró un efecto protector contra el daño tisular.

RESUMO

The aim of this study is to examine the changes in the amniotic membrane diagnosed with gestational diabetes mellitus. In this study, as a control group human amnion membrane from normotensive pregnancies was collected from diabetic women at 28­35 weeks of gestation. Gestational diabetes (n= 6) and normal amnion membrane (n= 6) for a total of 12 units were received. Amniotic membrane thickness was measured (p<0.0001) and it was significantly higher in GDM groups compared to control group. The diameter of the amniotic epithelial cell nuclei was measured (p=0.0022). Gestational diabetes results show that there was weakening between amniotic epithelial cell-cell junction. This study showed that structural changes in epithelial cells of amniotic membrane were formed due to diabetes. The membrane thickness has led to structural changes in diameter and in diabetes group cause extracellular matrix to increase, thus leading to MMP-9 expression increase eventually disrupting matrix balance. In addition, with cd44 increase angiogenesis has been induced and thought to influence material pass between fetus and mother.


El objetivo de este estudio fue examinar los cambios en la membrana amniótica diagnosticada con diabetes mellitus gestacional (DMG). En este estudio, como grupo control, se recogió la membrana amniótica de embarazos normotensos de mujeres diabéticas a las 28 y 35 semanas de gestación. La muestra consistió en 6 casos con diabetes gestacional (n = 6) y 6 casos de membrana amniótica normal (n = 6), para un total de 12 casos. El espesor de la membrana amniótica se midió (p <0,0001) y fue significativamente mayor en los grupos de DMG en comparación con el grupo control. Se midió el diámetro de los núcleos de las células epiteliales amnióticas (p = 0,0022). Los resultados demostraron que en la DMG hubo debilitamiento entre la célula epitelial amniótica-célula de unión. Este estudio mostró que los cambios estructurales en las células epiteliales de la membrana amniótica se presentaron debido a la DMG. El espesor de la membrana ha dado lugar a cambios estructurales en el diámetro y en el grupo de DMG debido a un aumento de la matriz extracelular, lo que condujo al aumento de la expresión de MMP-9, eventualmente interrumpiendo el equilibrio de la matriz. Además, el aumento de cd44 indujo la angiogénesis y se cree que también influye en el material que se comparte entre el feto y la madre.

RESUMO

A total of 32 Wistar rats were divided into four equal groups: (I) sham, (II) ischemia, (III) reperfusion and (IV) Potentilla fulgens. In groups I and II, ovary torsion was not performed and no drug was administered. In group III, 1 h of ischemia and 2 h of reperfusion were performed and no drug was given. Group IV received 400 mg/kg/day Potentilla fulgens intraperitoneally 5 days before Ischemia-reperfusion. All the parameters were observed to be significantly decreased (P<0.05) in all the experimental groups compared to the control group. In the sections of the ischemia-reperfusion group, degeneration of epithelium, dilation of blood vessels were observed. Potentilla fulgens administration reduced the morphological changes by induced I/R; in particular, infiltration, hemorrhage and vascular dilatation were decreased. Potentilla fulgens application during torsion, it plays an important role in maintaining the epithelial structure with E-cadherin expression. We suggest that PECAM-1(CD31) are a regulator of the microvascular response of the tubal mucosa.


Un total de 32 ratas Wistar fueron divididas en cuatro grupos: (I) Sham, (II) isquemia, (III) reperfusión y (IV) Potentilla fulgens. En los grupos I y II, no se realizó la torsión de ovario y ni se administró ningún tipo de fármaco. En el grupo III, se produjo isquemia por 1 h seguido de reperfusión por 2 h (I/R), sin administracion de fármacos. El grupo IV recibió 400 mg/kg por día de Potentilla fulgens vía intraperitoneal durante cinco días previo al protocolo de isquemia-reperfusión. Se observó que todos los parámetros disminuyeron significativamente (P <0,05) en todos los grupos experimentales en comparación con el grupo control. En las secciones del grupo de isquemia-reperfusión, se observó degeneración del epitelio y dilatación de los vasos sanguíneos. La administración de Potentilla fulgens reduce los cambios morfológicos inducidos por I/R; en particular, la infiltración, la hemorragia y la dilatación vascular. La aplicación de Potentilla fulgens durante la torsión, desempeña un papel importante en el mantenimiento de la estructura epitelial con la expresión de E-cadherina. Sugerimos que PECAM-1 (CD31) es un regulador de la respuesta microvascular de la mucosa tubárica.

RESUMO

OBJECTIVE: The purpose of this study was to investigate the effect of diurnal variation on biochemical results of first trimester aneuploidy screening test. METHODS: A total of 2725 singleton pregnant female, who had normal fetal nuchal translucency (NT) thickness, were included in the study during this period. Individuals were divided into two groups according to the sampling time (morning group: 09:00-11:00 am and afternoon group: 02:00-04:00 pm). Hormonal parameters (free-beta human chorionic gonadotropin [free ß-hCG] and pregnancy-associated plasma protein-A [PAPP-A] multiples of median [MoM] levels) of first trimester (11(+0)-13(+6) weeks) combined aneuploidy screening test were compared between morning and afternoon groups. RESULTS: PAPP-A MoM levels were significantly lower in the afternoon group when compared to the morning group (p = 0.001), whereas free ß-hCG MoM levels were similar in the both groups (p = 0.392). Rate of high risk for Down syndrome (Combine risk >1/300) and amniocentesis ratio were found higher in the afternoon group than morning group, but there were no difference between groups for the number of fetuses with Down syndrome. CONCLUSION: Receiving the venous blood sample for first trimester aneuploidy screening test in the afternoon causes low PAPP-A MoM levels.

RESUMO

Sarcoidosis is a multisystem inflammatory disorder of unknown etiology. It shows a great variety of clinical presentation, organ involvement, and disease progression. Lungs and lymphoid system are the most common sites involved with a frequency of 90% and 30%, respectively. Extrapulmonary involvement of sarcoidosis is reported in 30% of patients and abdomen is the most frequent site. Furthermore, peritoneal involvement is extremely rare in sarcoidosis. The case presented here described peritoneal manifestations of sarcoidosis without involvement of lungs. A 78-year-old woman possessing signs of malignancy on blood test and abdominal magnetic resonance imaging underwent laparatomy with a suspicion of ovarian malignancy. The macroscopic interpretation during surgery was peritoneal carcinomatosis. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, peritoneal biopsies, total omentectomy, and appendectomy were performed. Final histopathological result revealed the diagnosis of sarcoidosis. Clinicians must keep in mind that peritoneal sarcoidosis can mimic intra-abdominal malignancies.

RESUMO

BACKGROUND: Hydronephrosis is frequently encountered in advanced stage cervical cancers, and may be associated with mortality. In the present study, we aimed to demonstrate the effect of hydronephrosis on survival in patients with inoperable advanced stage cervical cancer. MATERIALS AND METHODS: The study data were acquired by retrospective analysis of the patient records belonging to 165 women with FIGO (International Federation of Gynecology and Obstetrics) stage-IIIB or more advanced cervical cancer, which were not surgical candidates. Parameters including patient age, pathological diagnosis, disease stage, pelvic sidewall extension, presence of hydronephrosis and administration of chemoradiation were analyzed. Further, the effects of these variables on survival were assessed. P values less than 0.05 were considered statistically significant. RESULTS: The distribution of the study patients according to disease stage was as follows: 131 (79.4%) had stage-IIIB, 18 (10.9%) had stage-IVB and 16 (% 9.7) patients had stage-IVA disease. Hydronephrosis was not evident in 91 (55.2%) of these patients, whereas 41 (24.8%) had unilateral and 33 (20%) patients had bilateral hydronephrosis. When compared to mean survival in patients who did not have hydronephrosis, survival was significantly shortened in patients who had bilateral and unilateral hydronephrosis (p<0.05). There was no significant survival difference between patients with unilateral and bilateral hydronephrosis (p>0.05). Although patient age, pathological type, pelvic involvement, and chemotherapy treatment rates were similar (p>0.05), radiotherapy requirement rate and disease stage were significantly different among the study groups (p<0.05). CONCLUSIONS: Hydronephrosis was found to be a significant predictor of poor survival in patients with advanced stage cervical cancer, irrespective of unilateral or bilateral involvement.While waiting for future studies with larger sample sizes, we believe that the FIGO stages in advanced cervical cancer could further be stratified into subgroups according to presence or absence of hydronephrosis.

RESUMO

PURPOSE: The purpose of the study is to evaluate the effect of vardenafil on the histopathology and biochemical parameters in reducing damage in experimental ovarian ischemia and ischemia/reperfusion injury in a rat model and to compare the effect of two different doses of vardenafil. METHODS: Forty-two rats with experimental ovarian torsion. Group-I: sham; Group-II: ovarian ischemia; Group-III: 2 hours of ischemia followed by a 2-hour reperfusion. Group-IV: two hours before the sham operation, rats received 1mg/kg vardenafil; Group V and VI: A 2-hour period of ovarian ischemia was applied, in which rats were treated with intraperitoneal vardenafil 1 and 2mg/kg dose, after 1.5 hours of ovarian ischemia. After 2 hours of reperfusion, the ovaries on the right side were removed for examination. The ovarian ischemia/reperfusion injury was evaluated by calculating total antioxidant status, total oxidant status and oxidative stress index; and histopathologic examination of all ovarian rat tissue. RESULTS: The histologic findings in vardenafil treatment groups were statistically significant decreased edema and follicle degeneration, with vascular congestion, hemorrhage and follicle degeneration being dose-dependent. There were no statistically significant changes in the biochemical parameters. CONCLUSIONS: According to histopathological examination, low and high dose vardenafil is effective in attenuating ischemia-reperfusion induced ovary injury.

RESUMO

BACKGROUND: The present study aimed to investigate the utility and importance of the various parameters of complete blood count panel for benign-malignant differentiation of adnexal masses. MATERIALS AND METHODS: This retrospective study involved 316 patients with documented benign and 253 patients with malignant adnexal masses who underwent primary surgical treatment at a tertiary referral center. Prior to the study, all benign and malignant cases were compared within their own groups and then the benign and malignant cases were compared to each other. For all cases, cut-off, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for the neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), neutrophil, lymphocyte, platelet and CA-125 parameters, and the results were compared in regards to the groups. RESULTS: NLR, PLR, neutrophil, CA-125, and platelet values were higher in the malignant compared to the benign cases (p<0.01). The lymphocyte value was lower in the malignant cases (p<0.01). No significant differences were found for basophils and eosinophils (p > 0.05). For CA-125, the sensitivity, specificity, PPV and NPV for all cases were 78%, 62%, 62% and 78%, respectively. For NLR, they were 65.6%, 72.1%, 65.3%, and 72.3%, and for PLR, 48%, 81%, 67%, and 66%. Additionally, the sensitivity and specificity were 55% and 77% for CA-125, 66% and 58% for NLR, and 61% and 58% for PLR in early malignant cases. CONCLUSIONS: NLR and PLR appear to be useful methods that can be applied together with CA-125 due to the relatively high sensitivity values for the malign-benign differentiation of ovarian masses. Although the specificity of these parameters is lower than CA-125, especially in cases with early malignant ovarian pathology, their sensitivity being higher is promising for the early diagnosis of ovarian cancer. It can be used to detect ovarian malignancies in the early stages, and it will increase the treatment options and improve survival rates.

RESUMO

OBJECTIVE: To investigate the risk factors potentially associated with high-risk human papillomavirus (HPV) persistence in women undergoing cold-knife conization (CKC) for treatment of high-grade cervical intraepithelial neoplasia (CIN). METHODS: Medical records of women who underwent CKC for treatment of CIN 2/3 between 2007 and 2012 at a tertiary hospital in Ankara, Turkey, were retrospectively analyzed. Cases involving persistent HPV infection after 1 year of follow-up were identified. Using univariate and multivariate analyses, the impact of various factors such as patient age, menopausal status, parity, high-risk HPV type, excised cone dimensions (width, height, and depth), and surgical margin status on high-risk HPV persistence was assessed. RESULTS: A total of 292 women underwent CKC for treatment of CIN 2/3 within the study period. After women with a subsequent diagnosis of cervical cancer, subsequent total hysterectomy, and inadequate follow-up data were eliminated, 113 women were eligible for final analysis. High-risk HPV persistence was detected in 24 (21.2%) women, and multivariate analysis revealed that patient age and cone depth were significant independent predictors (P < 0.05). CONCLUSION: High-risk HPV persistence may be encountered after CKC procedures. It is important to evaluate persistent HPV infections after treatment because affected women are at increased risk for disease persistence, recurrence, and progression.

RESUMO

OBJECTIVE: To determine whether inherited thrombophilia affects components of first trimester combined aneuploidy screening test. METHOD: A case-control study was performed between January 1st and December 31st 2011, at a tertiary referral hospital. Singleton pregnancies with inherited thrombophilia that underwent first trimester (11-13(+6) week) combined aneuploidy screening test were included in the study. Pregnancy associated plasma protein-A (PAPP-A), free beta-human chorionic gonadotropin (fbHCG) and fetal nuchal translucency (NT) were compared between the study group and controls. RESULTS: Within the study period, 15,881 women with singleton pregnancies had a combined first trimester aneuploidy screening test at our institution. Among these, 207 women met the inclusion criteria. A control group that comprised 625 women with similar gestational age was generated, using a 1:3 ratio. PAPP-A levels were significantly higher, whereas fbHCG levels and fetal NT measurements were lower in women with inherited thrombophilia (p < 0.001). CONCLUSION: Our study suggested that PAPP-A, free b-HCG and NT MoM levels display alterations in women with inherited thrombophilia. Future trials are needed to assess the need for readjustment of risk in these patients.

RESUMO

OBJECTIVE: To outline and discuss the clinical features and outcomes of adnexal masses that were treated during cesarean delivery at a tertiary referral hospital located in Ankara, Turkey. METHODS: The operating room and pathology department databases for 2007-2012 were retrospectively reviewed for surgically managed adnexal masses during cesarean delivery. Clinicopathologic characteristics and maternal and neonatal outcomes were assessed. RESULTS: Adnexal masses occurred in 151 women (0.3% of all cesarean deliveries). Most (54.9%) masses were incidentally discovered during cesarean delivery. The mean mass size was 5.3±3.7cm (range, 3-30cm). The majority (96.7%) of the women underwent excision of the mass and ovarian repair. Most masses were benign, with dermoid cysts constituting the most common diagnosis (23.8%). Rare tumors such as thecoma, hyperreactio luteinalis, hemangioma, and benign Brenner tumor were also encountered. Three (2.0%) women were postoperatively diagnosed with ovarian cancer. Preterm delivery and neonatal intensive care unit admission rates were 15.9% and 11.9%, respectively. There were no serious neonatal morbidities and no neonatal mortality. CONCLUSION: Adnexal masses encountered during cesarean delivery generally have a favorable prognosis in terms of maternal and fetal outcome.

RESUMO

BACKGROUND: Colposcopy is the gold standard procedure for evaluating cervical cytological abnormalities. Although it is essentially a minimally invasive intervention, referral for colposcopy may cause significant distress on patients. In this study, we aimed to determine if pre-procedural anxiety levels have a significant association with procedure related pain and discomfort in women undergoing colposcopy for evaluation of abnormal cervical cytology. We also assessed the impact of various clinical factors on anxiety, pain and discomfort in these patients. MATERIALS AND METHODS: This prospective study was performed at the Gynecologic Oncology Department of Zekai Tahir Burak Women's Health Education and Research Hospital in Ankara, Turkey between January and June 2013. After taking informed consent, State-Trait Anxiety Inventory (STAI) form and a 14-item questionnaire were filled for women who were admitted to our outpatient colposcopy unit for evaluation of abnormal cervical cytology. STAI scores were calculated for each participant. Immediately after the procedure, visual analog scale (VAS) scores for procedure-related pain and discomfort were obtained. Associations between STAI and VAS scores were investigated using correlation analyses. The effect of various contributing factors on anxiety, pain and discomfort were evaluated with linear regression analysis. The p values less than 0.05 were considered statistically significant. RESULTS: A total of 222 women met the inclusion criteria within the study period. Mean patient age was 38.5±9.6. Median state and trait anxiety scores were 47 and 46, respectively. Median VAS scores for pain and discomfort were 4 for both variables. State anxiety had a significant correlation with procedure related discomfort (p=0.02). Colposcopy related pain VAS scores were significantly affected by state anxiety level, marital status and prior gynecological examination (p<0.05). Colposcopy related discomfort VAS scores were significantly affected by state anxiety level, marital status, prior gynecological examination and educational status. CONCLUSIONS: Additional measures should be implemented in women that carry higher risk for experiencing pain and discomfort. Social, cultural and lifestyle issues may also affect women's experiences during colposcopy, therefore further studies are needed to define specific determining factors in various populations.

RESUMO

BACKGROUND: A small but significant proportion of cases with atypical squamous cells of undetermined significance (ASCUS) may harbour CIN 2-3, or even invasive carcinoma. Although immediate colposcopy, HPV-DNA testing or expectant management are three recommended options in ASCUS triage, a consensus does not currently exist on which one of these approaches is the most efficient. In this study, we aimed to compare the performance and cost of immediate colposcopy and colposcopy based on the human papillomavirus (HPV) testing for detecting histologically confirmed high-grade cervical intraepithelial neoplasia (CIN) in women with ASCUS. MATERIALS AND METHODS: Records of 594 women with an index Papanicolaou smear showing ASCUS were retrospectively analyzed. Women in the immediate colposcopy arm were referred directly to colposcopy (immediate colposcopy group, n=255) and those in the HPV triage arm were proceeded to colposcopy if the high-risk HPV (hrHPV) test was positive (HPV triage group, n=339). High grade CIN (CIN2+) detection rate and treatment costs were compared between the groups. RESULTS: The detected rate of CIN2+ was higher in the HPV triage group compared to immediate colposcopy group (8% vs. 1.6%, p=0.011). In the HPV triage group, the total cost, cost per patient, and the cost for detecting one case of high grade CIN were higher than the immediate colposcopy group (p<0.001). CONCLUSIONS: In women with ASCUS cytology, HPV DNA testing followed by colposcopy is more costly than immediate colposcopy, but this approach is associated with a higher rate of CIN2+ detection. This findings suggest that HPV DNA testing combined with cervical cytology could reduce the referral rate to colposcopy.

RESUMO

OBJECTIVE: The purpose of this study was to assess the awareness and knowledge regarding human papillomavirus (HPV), HPV related conditions and HPV vaccine among nursing students, and to identify their attitudes towards HPV vaccination. MATERIALS AND METHODS: The study was carried out at a tertiary Women's Health Care Center in Ankara, Turkey. Self-administered questionnaires were filled out individually by the nursing students and by a control group including similar aged women. Data regarding demographic information, knowledge and awareness about HPV infection and HPV vaccine, attitudes towards vaccination, acceptance of HPV vaccine and assessment of HPV vaccination attitudes of the nurses with respect to the gender of their children was assessed and recorded. RESULTS: A total of 752 participants was included in the analysis. Five hundred and twenty (69.14%) of the participants were nursing students and the rest (n=232; 30.8%) were control group. The mean ages of the nursing students and the control group were 19.4 (16-27) and 19.4 (16-25) years, respectively. Majority of the nursing students knew the causal relationship between HPV and cervical cancer. Seventy-eight percent of the nursing students and 22.4% of the control group stated that they had heard of HPV vaccine. While the rate of the willingness to be vaccinated was 33.7% in the nursing student group, it was only 13.4% in the control group. CONCLUSION: The awareness and knowledge about HPV, its relation with cervical cancer and prevention of cervical cancer by HPV vaccine were favorable among nursing students at a tertiary hospital in Ankara, Turkey. However, although aware of the theoretical implications, they did not seem to apply it to practice, such as not having regular gynecologic examinations and Pap smears. Thus, further studies are needed to evaluate the factors that affect practical applications of health care professionals responsible for providing health education to the public.

RESUMO

Proliferating trichilemmal tumor (PTT) is a rare but morphologically distinct tumor that usually arises on the scalp of elderly women. It is composed of multiple cysts consisting of squamous epithelium with trichilemmal keratinization without granular layer interposition. Vulvar proliferating trichilemmal cyst is very rare, with, to the best of our knowledge, only 3 cases previously reported in the literature. We describe a 39-year-old woman with recurrent PTT on the left labium majus of the vulva, which had been excised from the same side 5 years before. She had a palpable nodule, approximately 2 cm in size, which was firm, mobile, and nontender; without erythema and ulceration; and covered by normal skin on the vulva. There was no inguinal lymphadenopathy. The lesion was removed by wide surgical excision; because of the tissue elasticity, primary closure was possible. The pathology result was reported as proliferating trichilemmal carcinoma with tumor-free margins. Although local recurrence after wide excision is rare, we recommend complete excision for treatment of PTT and long-term follow-up because of the possibility of recurrence.
