RESUMO

This study aimed to determine the protective role of l-ascorbic acid in a pregnant rat model of cadmium-induced toxicity. Cadmium is a toxic heavy metal that can seriously harm placenta and fetus tissue in pregnant women. Forty-two healthy female Wistar albino rats (250-300 g weight and 14-16 weeks) were randomly distributed into six equal groups (n = 7): control, cadmium 1 mg (CD1), cadmium 5 mg (CD5), ascorbic acid (AA), CD1+AA, CD5+AA. Cadmium was administered to pregnant rats by oral gavage every other day, and/or AA (200 mg) was administered every day. At the end of pregnancy (Day 21), blood, placenta, and fetuses were collected from rats. The results indicated that cadmium-induced oxidative stress by increasing the level of MDA and by decreasing the levels of GSH, SOD, and CAT activity in the serum of maternal. However, AA administration significantly decreased MDA levels and increased GSH levels, SOD, and CAT activity (p < 0.05). Cadmium (5 mg/kg) exposure significantly increased creatinine levels compared to AA and CD1+AA groups (p < 0.05). In addition, AA (200 mg/kg) significantly attenuated cadmium-induced histopathological alteration in the placental and fetal tissues. In conclusion, AA may prevent cadmium toxicity in maternal and fetal tissues, as it regulates oxidative imbalance in pregnant rat tissues and alleviates histopathological changes.

RESUMO

This study aimed to analyze immunohistochemical staining and pathological data in cervical intraepithelial neoplasia (CIN) and squamous cell cervical carcinoma (SCC) with abnormal colposcopic findings. A histopathological evaluation of 45 low-grade squamous lesions (LSILs), 177 high-grade squamous lesions (HSILs) and 16 SCC biopsy materials from existing slides was obtained from blocks obtained from the archive. In addition, SOX-2 immunohistochemical staining was evaluated. The mean age of the HSIL group was 43.20 ± 8.97 years, younger than the mean age of the LSIL group of 51.62 ± 9.64 years (p = 0.000). There was no difference between the groups regarding the method of biopsy (p > 0.05). Endocervical gland involvement was not observed in the LSIL group, but was observed in 66 (37.3%) biopsy materials in the HSIL group (p = 0.000). There was a difference between the groups in terms of the level of CIN at the surgical margin (p = 0.000). Ki-67, SOX-2 staining percentage and p16INK4a positivity were higher in the HSIL group than in the LSIL group (respectively, 67.57 ± 19.10 vs. 14.62 ± 7.11, p = 0.000; 27.72 ± 31.56 vs. 10.09 ± 15.38, p = 0.003; 66 (82.5%) vs. 8 (44.4%), p = 0.001). While there was no difference in SOX-2 intensity between the HSIL and LSIL groups (p > 0.05), it was statistically significantly higher in the SCC group (p = 0.000), as was the percentage of SOX-2 (p = 0.000). We have shown that p16INK4a and SOX-2 staining is useful, in addition to Ki-67 immunostaining, which is widely used for SCC, which is one of the preventable cancer types. In addition, SOX-2 may provide a glimmer of hope in the development of SCC treatment modalities, especially since it is aggressively elevated in SCC rather than CIN lesions.

RESUMO

We aimed to evaluate the expression of YAP1, PTEN, VEGF in the placentas of patients with preeclampsia and placentas of healthy pregnant women for trophoblast invasion, which is similar to cancer etiopathogenesis. The placentas of 70 women who gave birth, including 30 preeclampsia and 40 healthy controls, were evaluated. YAP1, PTEN and VEGF immunohistochemical staining were performed using the microarray method on placental tissue. The mean ± standard deviation for YAP1, PTEN and VEGF intensity were; 1.57 ± 0.71,2.59 ± 0.80, 1.61 ± 0.59, respectively. PTEN intensity was statistically significantly lower in the preeclampsia group than in the control group (2.37 ± 0.99 vs 2.75 ± 0.58, p = .049). There was no difference between the groups in terms of YAP1 and VEGF staining (p > .05). The etiopathogenesis of preeclampsia is still unclear. However, since trophoblast invasion and endothelial repair have similar aspects with cancer mechanisms, both preeclampsia and cancer studies are progressing by supporting each other. Our study is a prototype study showing that large-participation studies can be carried out easily by using the microarray method as an economic model.

RESUMO

OBJECTIVES: Cellular interactions and cell adhesion underlie preeclampsia (PE). The aim of the current study is to investigate the role of cell adhesion molecules such as CD97, neural (N)-cadherin, epithelial (E) -cadherin and integrin beta-4 in PE. METHODS: This prospective study included 20 pregnant women with PE and a control group of 16 healthy pregnant women who were matched for age, gestational age, gravida and parity. Standard blood tests and placental cell adhesion molecule immunohistochemical staining were examined. RESULTS: The creatinine, uric acid and lactate dehydrogenase (LDH) levels from standard blood tests were found to be statistically higher in the PE group (p = 0.002, p = 0.000, p = 0.001; respectively). In the PE group, the CD97 maternal serum level was statistically significantly lower, as was its immunohistochemical expression in placental sections (p = 0.028, p = 0.000; respectively). The E-cadherin expression score was statistically higher in the PE group compared to the control group (3,65 ± 1,84 vs 2,06 ± 1,76 respectively; p = 0.003). The N-cadherin expression score was statistically lower in the PE group compared to the control group (1,50 ± 0,82 vs 2,43 ± 1,59 respectively; p = 0.049). Integrin beta-4 was not statistically different between groups. CONCLUSIONS: Cellular interaction may be responsible for PE as in cancer. A balance in intercellular communication, as researched in cancer therapy, may offer the solution in PE.

RESUMO

BACKGROUND: TNF-α, IL-6, and TGF-ß are important bio mediators of the inflammatory process. This experimental study has investigated inflammatory biomarkers' efficacy to determine the appropriate period for anastomosis surgery in tracheal stenosis cases. METHODS: First, a pilot study was performed to determine the mean stenosis ratio (SR) after the surgical anastomosis. The trial was planned on 44 rats in four groups based on the pilot study's data. Tracheal inflammation and stenosis were created in each rat by using micro scissors. In rats of groups I, II, III, and IV, respectively, tracheal resection and anastomosis surgery were applied on the 2nd, 4th, 6th, 8th weeks after the damage. The animals were euthanized 8 weeks later, followed by histopathological assessment and analysis of TNF-α, IL-6, and TGF-ß as biochemical markers. RESULTS: Mean SR of the trachea were measured as 21.9 ± 6.0%, 24.1 ± 10.4%, 25.8 ± 9.1%, and 19.6 ± 9.2% for Groups I to IV, respectively. While Group III had the worst SR, Group IV had the best ratio (p = 0.03). Group II had the highest values for the biochemical markers tested. We observed a statistically significant correlation between only histopathological changes and TNF-α from among the biochemical markers tested (p = 0.02). It was found that high TNF-α levels were in a relationship with higher SR (p = 0.01). CONCLUSION: Tracheal anastomosis for post-traumatic stenosis is likely to be less successful during the 4th and 6th weeks after injury. High TNF-α levels are potentially predictive of lower surgical success. These results need to be confirmed by human studies.

RESUMO

PURPOSE: To determine the prevalence of oropharyngeal high-risk human papillomavirus (HPV) in patients undergoing tonsillectomy by detection of high-risk HPV in tonsil tissues using the in situ hybridization (ISH) technique. MATERIALS AND METHODS: The patients who underwent tonsillectomy between 2014 and 2018 were examined retrospectively. The pediatric cases and patients who underwent tonsillectomy due to malignancy were excluded. The study included 270 adult cases selected by age and gender randomization. The tonsillar tissue of each case was re-examined by the pathology department, and the presence of high-risk HPV was investigated via the ISH technique. Multiple logistic regression models were used for predictions of different factors. RESULTS: The prevalence of high-risk HPV in the 270 patients (male: 154 [57%]; female: 116 [43%]; mean age: 36.44 ± 12.87 years) was found to be 6.7% (n = 18). The prevalence was found 8.4% in men and 4.3% in women; 8.9% in cases under the age of 40 and 2.9% in cases over the age of 40; and 10.9% in patients who underwent tonsillectomy for infectious indications and 2.3% for non-infectious indications. Multivariate analysis identified that the infectious indications for tonsillectomy were significantly associated with high-risk HPV positivity (OR 5.328; p = 0.009). CONCLUSIONS: The prevalence of oropharyngeal high-risk HPV was found to be 6.7% and higher in younger people and men. Additionally, the HPV positivity was found to be higher in patients who underwent tonsillectomy for infectious indications. To our knowledge, this is the first study that reports the correlation between recurrent tonsil infections and HPV positivity in tonsil tissue.

RESUMO

OBJECTIVE: This study aimed to determine the factors associated with Human Papillomavirus (HPV) persistence in women undergoing cervical excision for pre-invasive lesions, after they have been referred from a primary HPV screening program. METHODS: A retrospective study design involving patients who were treated at a Cervical Disease Screening and Treatment Unit, in a university hospital setting. After initial treatment, cervical HPV infection status was analyzed at the sixth month, first year and then subsequently after the second year. RESULTS: Totally, 395 patients who were diagnosed with pre-invasive cervical lesions and who subsequently undergone cervical excision were identified. In the first-year visit after cervical excision, HPV 18 was cleared in almost all (95.8%) cases, followed by HPV 16 (69.9%) and other hrHPV types (65.6%). Available data documented that 88.6% of women reached clearance after the two-year follow-up. Univariate analysis revealed a significantly higher proportion of HPV clearance among women who were younger (p = 0.019), premenopausal (p = 0.002), and who had been found to have a negative cytology result on their initial Pap test (p = 0.018). However, only cervical cytology result remained as the independent predictor of HPV persistence on a multivariate logistic regression (OR 0.43; 95% CI 0.21-0.87; p = 0.019). CONCLUSIONS: A low risk of HPV persistence was found among every HPV genotype in women undergoing cervical excision for pre-invasive cervical lesions. Initial cervical cytology result was the only independent predictor of HPV clearance during surveillance, which indicates the prognostic value of Pap test in primary HPV screening.

RESUMO

Osteomas are located mostly in the mandible followed by paranasal sinuses such as frontal sinuses, ethmoid air cells, maxillary sinuses and rarely based on nazal cavitiy or turbinate. The osteoma located on outside of nazal bone is extremely rare. The authors report an unusual patient of nasal bone osteoma associated with aesthetic problem on nasal dorsum. Outer side of nasal bone osteoma in large diameter causes aesthetic problems. The authors believe that open rhinoplasty approach is successful in this type of patients.

RESUMO

OBJECTIVE: Metastatic tumors of the mandible are rare and usually present clinically as growths. The prognosis of lung cancer patients with bone metastases is poor. CASE REPORT: This article shows a metastasis from adenocarcinoma of the lung affecting the mandible of a 75-year-old female patient where the metastatic lesion was detected before primary tumor. The patient were treated with radiation therapy with palliative and antalgic intent. But the patient died 8 weeks after the diagnosis. CONCLUSION: Radiation therapy was effective and well tolerated in the case. Bone metastases particularly mandible metastasis of lung cancer has poor prognosis. Palliative and supportive therapy may be firstly chose because of poor prognosis.

RESUMO

AIM: To investigate the anal component of the anogenital Human Papillomavirus (HPV) related disease during surveillance of patients treated for cervical intraepithelial neoplasia (CIN). METHODS: Patients were analyzed within two groups according to the histopathological examination of the cervical biopsies: Low-Grade Squamous Intraepithelial Lesion (LSIL) and High-Grade Squamous Intraepithelial Lesion (HSIL) groups. Anal specimens were also collected in the first-year follow-up visit. RESULTS: All patients had cervical high-risk HPV (HR HPV) infection at admission. At the first-year follow-up, positive HR HPVs were found in 47% of cervical samples. Despite this clearance, the anal HPV infection rate after the first year was 42.5% and 39.6% in LSIL and HSIL groups. Amongst the HSIL group, anal HR HPV positivity was observed in 29.6% of cases without any cervical HPV infection. CONCLUSION: A group of women cured of high-grade lesions have ongoing anal HPV infection. It is reasonable to propose that detecting anal HPV could impact the patient's treatment process. Therefore, prospective studies are needed to investigate this group of women's clinical outcomes and define the clearance rate of cervical HPV infection when anal HPV persists.

RESUMO

Objective: The role of baseline and post-treatment standardized uptake value (SUVmax) values in predicting pathological response in patients with breast cancer after neoadjuvant chemotherapy (NAC). Materials and Methods: Thirty patients with invasive ductal breast cancer were included in this retrospective study. F-18 fluorodeoxyglucose (FDG) positron emission tomography/computerized tomography (PET/CT) examinations were performed before and after NAC. Pretreatment SUVmax (SUVmax I), post-treatment SUVmax (SUVmax II) and ΔSUVmax values of primary breast cancer were obtained. Breast tumor pathology preparations were examined for the evaluation of tumor response according to the Miller and Payne classification. Patients were grouped as responding to treatment (pCR) and unresponsive to treatment (nonpCR). In all analyses, p<0.05 was considered statistically significant. Results: The mean age of the 30 patients included in the study was 51.2±11.98 years. In the study-defined grouping, 13 patients (43.3%) were nonresponders and 17 patients (56.7%) were responders. ΔSUVmax was significantly greater in the responders group compared to the nonresponders group, while SUVmax II was lower (p = 0.001 and p = 0.004, respectively). There was no significant difference between the responders and nonresponders in terms of age, tumor diameter, and SUVmax I values. Multivariate logistic regression analysis showed ΔSUVmax to be the only independent predictive factor for pCR. Conclusion: F-18 FDG PET/CT was an effective method in evaluating the treatment response after NAC in breast cancer, and ΔSUVmax and post-treatment SUVmax can be used to predict the response of the primary tumor to treatment.

RESUMO

INTRODUCTION: This study aimed to analyse the relationship between clinicopathological factors in cervical intraepithelial lesions and abnormal colposcopic findings. MATERIAL AND METHODS: Thirty high-grade squamous intraepithelial lesion (HSIL) and thirty low-grade squamous intraepithelial lesion (LSIL) patients who underwent biopsy due to abnormal colposcopic findings were included in the study. The immunoreactivity of CD3, CD4, CD5, CD8, and PD-1 was analysed immunohistochemically in tumor-infiltrating lymphocytes (TILs) and stromal lymphocytes. RESULTS: In TILs, CD3, CD4, CD5, CD8, and PD-1 were highly stained in 20/30 (66.6%), 16/30 (53.3%), 15/30 (50.0%), 24/30 (80.0%), and 13/30 (43.3%) of the cases for the HSIL group, while 7/30 (23.3%), 4/30 (13.3%), 5/30 (16.6%), 9/30 (30.0%), and 5/30 (16.6%) were in the LSIL group, respectively. CD3, CD4, CD5, CD8, and PD-1 immunostainings for TILs were higher in the HSIL group (p=0.001, p=0.001, p=0.006, p˂0.001, p=0.024, respectively). Only PD-1 was significantly higher in lymphocytes in the stroma (p=0.001). CONCLUSIONS: CD3, CD4, and CD8 also show a positive correlation with the Ki-67 proliferation index. CD3, CD4, CD5, and CD8 may contribute to PD-1-mediated tumour control. Immunohistochemical staining plays a key role in evaluating the tumour microenvironment.

RESUMO

OBJECTIVES: In this study, we aimed to investigate the correlation between SUVmax of primary tumor and prognostic factors/molecular subtype in ductal breast cancer patients. MATERIALS AND METHODS: We retrospectively reviewed 150 female patients with pathologically proven invasive ductal breast cancer from January 2015 to October 2019 who underwent 18F-FDG PET/CT for initial staging. Histopathological prognostic features of the primary tumor (histological grade, hormone receptor status, Ki-67 index, vb.) were obtained from the tru-cut biopsy report. In 18F-FDG PET/CT studies, the maximum standardized uptake value (SUVmax) of the primary breast tumor was calculated and compared with the presence of axillary lymphadenopathy and/or distant metastases, histopathological prognostic factors and molecular subtype. RESULTS: The high SUVmax of primary breast tumors is significantly correlated with the clinicopathological factors: high tumor size, high histologic grade, high Ki-67 index, axillary lymph node positivity and distant metastasis. SUVmax value was significantly higher in patients with basal subtype than patients with Luminal A subtype (8,14 ±â€¯3,71 and 4,64 ±â€¯2,45, p = 0,002). Correlation analysis revealed a low correlation between Ki-67 index and SUVmax (r = 0,276, p = 0,001) and moderate correlation between tumor size and SUVmax (r = 0,470, p = 0,001). In multivariate linear regression analysis, Ki-67 index and tumor size had a statistically significant effect on SUVmax values. As these parameters increase, it is seen that it increases SUVmax values (p = 0,004, Std Beta: 0,228, 95% CI:0,010-0,055 and p = 0,001, Std Beta:0,374, 95% CI:0,55-0,136, respectively). CONCLUSION: High SUVmax value is associated with factors suggesting poor prognosis. Pretreatment 18F-FDG PET/CT can be used as a tool to predict prognosis in breast cancer.

RESUMO

BACKGROUND AND OBJECTIVE: Bladder cancer is the ninth most common type of cancer worldwide. We aimed to investigate the relationship between tumor grade, lamina propria invasion, muscularis propria invasion, and lymphovascular invasion and human epidermal growth factor receptor 2 (HER-2), cyclin D1, and alpha-methyl-CoA racemase (AMACR) expressions in bladder cancer. MATERIALS AND METHODS: The study included patients who underwent complete TURBT. In total, 72 cases of bladder cancer diagnosed by two pathologists were selected. AMACR, HER-2, cyclin D1 expressions were detected immunohistochemically. RESULTS: The study population comprised 80% (57) males and 20% (15) females (mean age, 68 years). Further, 35 cases were noninvasive and 37 invasive urothelial carcinoma and 38 patients had low-grade tumor and 34 high-grade tumor. Intense immunostaining was observed with cyclin D1 for 75% tumors, AMACR for 39%, and HER-2 for 86%. High expressions of cyclin D1 and AMACR were observed in high-grade tumors (P < 0.05 and P < 0.005, respectively). High expression of HER-2 (2 and 3 positive) was found both at low- and high-grade tumors (84% and 88%, respectively). CONCLUSION: Cyclin D1, AMACR expressions were found to be significant predictive factors of high-grade tumors. High Her-2 expression in patients with bladder carcinoma may indicate that they are potential targets for treatment. These markers may be important in determining prognosis of tumors and may be valuable for guiding treatment options.

RESUMO

OBJECTIVES: Ovarian cancer is a heterogeneous disease, where chronic inflammation plays a key role in carcinogenesis. In this study, it is aimed to analyze the relationship with prognosis and chemotherapy response to clinicopathologicalnvariables in epithelial ovarian cancers such as proliferation of PD-1 +, CD8 +, CD4 +, CD3 + T-lymphocytes infiltrating the tumor and tumor stroma. MATERIAL AND METHODS: Seventy-six cases diagnosed with primary epithelial ovarian tumor from biopsy or surgical resection materials were included in the study. Immunreactivity of CD3, CD4, CD8, PD1 was evaluated immunohistochemically in lymphocytes in tumor infiltrating lymphocytes and stromal lymphocytes. RESULTS: Seventeen (22.4%) of the cases were Type I, 59 (77.6%) of them were Type II ovarian carcinoma. PD-1 positivity was observed in stromal and intraepithelial lymphocytes in 22 (28.9%) of 76 cases. In the presence of PD-1 + T-lymphocytes that infiltrate tumor and stroma, disease-free survival are shorter (p = 0.037). The presence of stromal CD4 + and CD8 + T-lymphocytes was more common in late stage patients (p = 0.012, p = 0.036; respectively). The disease-free and overall survival rate was statistically significantly shorter in the presence of CD8 + T lymphocytes (p = 0.009, p = 0.003; respectively). CONCLUSIONS: CD3, CD4 and CD8 may contribute to PD-1 mediated tumor control. Anti PD-1 therapy may be an alternative to chemotherapy in PD-1 positive patients. Identifying patients who do not respond to chemotherapy through PD-1 expression prior to immunotherapy will help develop potential personalized immunotherapy.

RESUMO

OBJECTIVE: We aimed to analyze the clinicopathological findings, treatment approach, and treatmen outcomes in patients diagnosed with phyllodes tumor (PT). MATERIALS AND METHODS: The clinicopathological data of 26 patients with PT, who were treated between 2008 and 2019, were retrospectively analyzed. RESULTS: Mean age was 35.07±13.95 years (range: 14-71), while mean tumor size was 54.76±29.24 mm (range: 25-135). Benign, borderline, and malignant PT were detected in 18 (69.2%), 3 (11.5%), and 5 (19.2%) patients, respectively. Marginless excision was performed in 20 patients (76.9%), while six (23.1%) patients underwent mastectomy. A statistically significant correlation of tumor type with mean tumor size and mean age was observed (p=0.041 and p=0.013, respectively). Margin positivity on first excision was more frequent in the malignant tumors (p=0.02). No statistically significant correlation of PT type with presence of breast cancer in the family history, and tumor localization was observed (p=0.79 and p=0.13, respectively). Mean postoperative follow-up duration was 56 months (range: 6-147). Local recurrence was not observed in any of the patients. Lung and left vastus lateralis muscle metastases were encountered. The patient with lung metastasis became exitus because of the same reason 6 months after detection of the metastasis. CONCLUSION: PT is a rare fibroepithelial tumor of the breast that is characterized by a mixed histology seen in younger ages when compared to the classical breast tumors. The probability of PT should be considered in the presence of a rapid-growing mass in the breast. In addition, it should also be considered that the contribution of imaging techniques may be limited.

RESUMO

BACKGROUND: Studies suggest that tumour-infiltrating lymphocytes (TILs) and inflammation markers have independent roles in non-small cell lung cancer (NSCLC), but the relationship between the two pronostic factors remains unclear. In this study, we investigated TILs and inflammation markers in with patients advanced stage NSCLC and assessed the association of their levels with prognosis. MATERIALS AND METHODS: TILs were evaluated by immunohistochemical staining for cluster of differentiation 3 (CD3) and cluster of differentiation 5 (CD5) and by hematoxylin and eosin staining for non-specific lymphocyte. We investigated the localisation pattern of TILs in advanced stage NSCLC. We divided all cases into two groups: TILs-high and TILs-low groups, by 75th percentile of the population of. In our study, inflammation markers were assessed by C-reactive protein (CRP) and the neutrophil-to-lymphocyte ratio (NLR). RESULTS: The results showed that the presence of intra-tumoral high CD3+ and low CD5+ were an independent prognostic factor for overall survival (respectively, P = 0.022 and P = 0.025). Moreover, the high NLR and serum high CRP levels were associated with poor survival (respectively, P = 0.008; P = 0.027). In multi-variate survival analysis, the high CD3+ , low CD5+ , high NLR, tumour node metastasis (TNM) stage, depth of tumour invasion and lymph node metastasis remained independent prognostic factors (respectively, P = 0.018, P = 0.020, P = 0.024, P = 0.038, P = 0.020 and P = 0.047).The high NLR was detected negative correlation with intra-tumoral CD3+ and positive correlation with intra-tumoral CD5+ (respectively, r = -0.623, P = 0.012; r = 0.628, P = 0.028). CONCLUSIONS: This study is first report demonstrating the prognostic value of intra-tumoral low CD5+ with NSCLC. Increased CD3+ and low CD5+ was observed in patients with poor prognosis; the two molecules were correlated with NLR, suggesting that inflammation might be used as improve therapeutic efficacy to immunotherapy for advanced NSCLC.

RESUMO

BACKGROUND: Cervical cancer is the ninth most common cancer among females in Turkey. Cervical smear is a routine screening test used for the detection of cervical abnormalities and also it detects certain infections of the cervix. OBJECTIVE: To analyze cervical smear results of our clinic in order to determine most frequent pathology of the women in North Eastern Anatolia Region of Turkey. MATERIALS AND METHODS: In a retrospective study design, 8,495 cervical cytology cases diagnosed at the Pathology Department of the Regional Education and Research Hospital in Erzurum over the last one and half years extending from August 2012 to December 2013 were investigated. RESULTS: The most common diagnosis was found to be inflammation, 65.5 % (5,566 out of 8,495), and the least was squamous epithelial abnormalities 0.2% (13 out of 8,495). There was some variation among the three pathologists regarding diagnosis but findings for the latter. CONCLUSIONS: Regular cervical smear tests are one of the most important strategies in early diagnosis of cervical cancer but there are conflicting data regarding the prevalence of epithelial cell abnormalities in Turkey, and the reasons of this should be investigated.

RESUMO

OBJECTIVE: Mardin is an area of low socioeconomic level with low rates of contraceptive method use. Our aim in this study was to evaluate the effects of the contraceptive methods used in the area on epithelial cell abnormalities and vaginal flora changes. MATERIAL AND METHOD: Cervical smear samples received at the Pathology Department between 2010 and 2012 of 526 patients who had used a contraceptive method and 112 who had never used one were included in the study. The cases were divided into 3 groups as those using hormonal contraception (107, 20.3%), those using an intrauterine device (343, 65.2%) and those using a barrier method (76, 14.4%). The evaluation was made using the Bethesda 2001 criteria for cervical epithelial abnormalities and specific cervicovaginal infections. RESULTS: There was no significant difference between the groups for epithelial cell abnormalities while bacterial vaginitis (12%, p=0.03) and Trichomonas vaginalis (7.6%) were more common in the IUD users. The Actinomyces rate in RIA users was 1.3%. There was only 1 case of bacterial vaginitis in the barrier group and none of the other patients had a specific infection. DISCUSSION: We did not find a significant cytopathic effect of using a IUD or hormonal contraception in our study. There was a low rate of epithelial abnormality in the barrier method group. IUD was seen to increase the incidence of bacterial vaginitis, Trichomonas vaginalis and Actinomyces. We did not find a significant effect of hormone use on the vaginal flora.
