Item Neutrophil-to-Lymphocyte Ratio and Platelet-to-Lymphocyte Ratio in Discriminating Precancerous Pathologies from Cervical Cancer(HINDAWI LTD, 2019-01-01) Tas, Mustafa; Yavuz, Adem; Ak, Mehmet; Ozcelik, BulentPurpose. We aimed to determine the predictive value of several hematological markers of inflammation on the presence/absence of cervical cancer and also to determine their ability in discriminating precancerous cervical pathologies from cervical cancer. Materials and Methods. In this study, patients who presented to Acibadem Kayseri Hospital between May 2010 and June 2018 were evaluated. Forty patients with low-grade squamous intraepithelial lesions (LSIL), 40 patients with high-grade squamous intraepithelial lesions (HSIL), and 30 patients with cervical cancer (CC) were retrospectively included in this study. A control group of 70 healthy volunteers with normal cervical cytology was also included in the study. Results. The neutrophil-to-lymphocyte ratio (NLR) was significantly higher in patients with CC than in controls. The platelet-to-lymphocyte ratio (PLR) was significantly higher in patients with CC compared to those with LSIL and HSIL diagnoses and also controls (p<0.001). Logistic regression analysis revealed that age (OR: 1.075, 95\% CI: 1.020-1.132, p=0.007), NLR (OR: 1.643, 95\% CI: 1.009-3.142, p=0.047), and PLR (OR: 1.032, 95\% CI: 1.003-1.062, p=0.029) were predictors for the presence of CC. ROC curve analysis revealed that both NLR and PLR were predictive of CC with a cutoff value of 2.02 for NLR (71\% sensitivity and 60\% specificity, AUC: 0.682, p=0.004) and 126.7 for PLR (83\% sensitivity and 69\% specificity, AUC: 0.752, p<0.001). Conclusion. In addition to patients' age, determination of NLR and PLR values, which are simple, inexpensive, and readily available markers of systemic inflammation, may help in decision making precancerous pathologies of the cervix.Item Oral tadalafil reduces intra-abdominal adhesion reformation in rats(OXFORD UNIV PRESS, 2012-01-01) Kutuk, Mehmet Serdar; Ozgun, Mahmut Tuncay; Batukan, Cem; Ozcelik, Bulent; Basbug, Mustafa; Ozturk, AhmetCurrently, there is no ideal agent to prevent adhesion formation. We have shown that sildenafil, a phosphodiesterase-5 (PDE-5) inhibitor, reduces post-operative adhesion formation by vasodilatation and increases fibrinolytic activity. Here, we evaluated whether tadalafil, a long-acting PDE-5 inhibitor, decreases post-operative adhesion reformation in rats. Standardized lesions were created in Wistar albino rats by cauterization of uterine horns and abrasion of adjacent peritonium. The extent and severity of adhesions were scored on the 14th post-operative day and adhesiolysis was performed at the second laparotomy. Animals were then assigned randomly into two groups. The study group (n 11) received 10 mg/kg oral tadalafil by gavage 60 min before the second laparotomy and daily for 14 days afterwards. Controls (n 11) received the same volume of tap water for 14 days by gavage. Animals were killed 15 days after adhesiolysis and adhesions were scored blind during the third laparotomy. Basal adhesion scores at the time of the second laparotomy were comparable in the study and control groups. Scores for the extent of adhesion reformation in the study and control groups did not differ {[}median 1 (range 03) versus median 2 (range 13)
