Women with polycystic ovary syndrome (PCOS) carry a number of cardiovascular risk factors. Cardiovascular morbidity is elevated even in young women with PCOS. Low-grade chronic inflammation, reflected in elevated levels of serum C-reactive protein (CRP) and endothelial dysfunction have recently been linked to development of atherosclerosis. We compared high-sensitivity (hs)CRP concentrations and endothelium dysfunction in 37 women with PCOS and 25 control subjects matched as a group for age and body mass index (BMI). Arterial endothelium and smooth muscle function was measured by examining brachial artery responses to endothelium-dependent and endothelium-independent stimuli. Serum LH, testosterone, androstenedione, and fasting insulin levels were significantly higher in the PCOS group than the control group. The PCOS group was more insulin resistant than age- and BMI-matched control women. CRP concentrations were higher in PCOS women than the healthy control group (0.25 vs. 0.09 mg/dl). hsCRP concentrations were correlated with BMI, insulin sensitivity indices (homeostasis model assessment and quantitative insulin sensitivity check index), and endothelium-dependent vasodilation. The groups were well matched for baseline brachial artery diameter. There was a significant difference in endothelium-dependent (flow- mediated dilation) and endothelium-independent (sublingual nitroglycerin) vascular responses between the women with PCOS and the normal healthy control group (P = 0.002 and P = 0.01, respectively). Endothelium-dependent vasodilation was correlated with hsCRP concentrations and insulin resistance. In conclusion, this study is the first to demonstrate increased levels of hsCRP, endothelial dysfunction, and the relation with insulin resistance in young and normal-weight women with PCOS. Clinical strategies aimed at reducing insulin resistance may prevent early atherosclerosis in women with PCOS.

Abstract. The purpose of the study was to evaluate the plasminogen activator inhibitor-1 (PAI-1) levels and PAI-1 activity in young and lean women with PCOS and to compare with controls matched for age and weight. Thirty two women with PCOS and 25 weight and age-matched healthy controls participated in this study. Patients were evaluated clinically and by pelvic ultrasound and fasting blood samples were taken for hematological and biochemical tests. Fasting insulin, glucose, lipid profile, FSH, LH, PRL, testosterone, SHBG, 17-hydroxyprogesterone, androstenedione, PAI-1 antigen; PAI-1 activity, insulin sensitivity indices (HOMA and QUICKI) were measured. PAI-1 Ag and activity were significantly higher in PCOS women than healthy control group. PAI-1 levels were directly correlated with BMI, insulin levels and insulin sensitivity indices. PAI-1 activity was also correlated with insulin levels and insulin resistance. As a conclusion PAI-1 Ag levels and activity were increased in lean PCOS women and these were directly correlated with insulin resistance. The finding may contribute to evidence of increase risk of cardiovascular disease and anovulatory infertility in PCOS women. Plasminogen activator inhibitor-1 (PAI-1) is a 52 kD glycoprotein whose main role is in the inhibition of plasmin formation during plasminogen activation and fibrinolysis [9]. The relationship between PAI-1 levels and cardiovascular risk is not clear [10,11]. Moreover, some studies speculated that overproduction of PAI-1 leads to distortions in the ovarian plasminogenplasmin pathway and anovulation in women with PCOS [12,13]. PAI-1 levels and metabolic parameters that can affect the PAI-1 concentrations in women with PCOS are still under debate. Insulin resistance is found in women with PCOS independent of body mass index (BMI) [14]. In diabetic patients, insulin resistance correlated linearly with plasma concentrations of PAI-1 [15,16]. Elevated PAI-1 levels have been demonstrated in some studies of women with PCOS [13,17,18]. Therefore it has been suggested that insulin mediated elevation of PAI-1 may contribute to anovulatory infertility and increased risk of cardiovascular disease those were determined in women with PCOS. However most of these studies included obese or over-weight patient and control groups, so it was not clear from these studies whether the finding of raised PAI-1 levels in women with PCOS was independent of obesity or not. The present study was designed to evaluate PAI-1 levels and activity in young and lean women with PCOS and compare with

Objective Chronic otitis media is an inflammatory disease of the middle ear. The airflow in the nasal passage affects the development of mastoid air cells through the eustachian tube. Nasal and paranasal pathologies and their anatomical variations cause chronic sinonasal inflammation and affect the middle ear mucosa. This study aims to reveal whether the nasal and paranasal sinus variations in pediatric patients are a factor in developing chronic otitis media. Materials and Methods Eighty patients, with unilateral chronic otitis media, who were admitted to the otorhinolaryngology clinic between May 2015 and July 2019, were included in this retrospective study. The control group (Group 2) consisted of a total of 51 patients. None of the patients in Group 2 had otorrhea history and no signs of chronic otitis in their otoscopic examination, middle ear pathologies. The patient’s anatomical variations of the nasal cavity and sinuses were evaluated with CT by a radiologist Results Nasal septum deviation was found to be 53% in children with chronic otitis media. It was found 31.4% in the control group. Since the P value was found to be .04, this rate was considered as significant. Inferior concha hypertrophy was found to be 17.6% in the control group and 38.8% in the group with chronic otitis media, and this rate was considered significant since the P value was .035 Conclusion We detected that septum deviation and inferior concha hypertrophy increased chronic otitis media formation in children. All these studies show that cases causing nasal obstruction, such as septum deviation, have a negative effect on middle ear pressure and increase the rate of ear diseases
