Abstract
We investigated possible associations between the internal concentrations of POPs and correlations between blood and tumor tissue concentrations in patients who underwent surgery for breast cancer and breast reduction as controls. Genetic variations in CYP1A1, GSTP1, GSTM1, and GSTT1 and hOGG1 were evaluated to determine whether they represent risk factors for breast cancer. Certain POPs have been found to be associated with breast cancer development. GST-P1 polymorphism represented a significant risk for breast cancer with unadjusted OR. However, the GSTT1 null polymorphism represented a significant risk for breast cancer when OR adjusted for age and smoking status. CYP1A1 polymorphism was a significant risk factor for breast cancer, regardless of whether the OR was adjusted. These results suggest that exposure to certain POPs, GSTT1 and CYP1A1 polymorphisms, age, and smoking status are risk factors for breast cancer. In addition, the blood concentrations of some POPs represent surrogates for breast tissue concentrations.

Abstract
BACKGROUND Delayed cord clamping is the standard of care for both term and preterm infants worldwide. The aim of this study was to evaluate the effect of 60-second or 180-second delayed cord clamping during labor on cerebral oxygenation and cardiac function. METHODS Healthy newborns were divided into two groups: a 60-second delay in cord clamping (60-s DCC) and a 180-second delay in cord clamping (180-s DCC) at birth. Pulse oximetry and cerebral near-infrared spectroscopy (cNIRS) probes were placed during postnatal care. A total of 84 healthy newborns were included in this study. Preductal oxygen saturation (SpO2), heart rate, and cNIRS values were recorded at 5 and 10 minutes after delivery. The cardiac function of the infants was assessed by echocardiography at 3-7 days postnatally. RESULTS There was no significant difference between the groups in SpO2 and cNIRS values at 5 and 10 min. While there was no significant difference in the number of neonates with targeted SpO2 at the 5th and 10th min and targeted cNIRS values at the 10th min, there was a significant difference in the number of neonates with target cNIRS values at the 5th min between groups (p < 0.001). Echocardiographic findings showed that pulmonary flow velocity was increased in the 180-s DCC group; the difference was statistically significant (p = 0.04). CONCLUSION Our results showed that the number of infants with normal cNIRS values regarding cerebral oxygenation was higher in the 180-s DCC group. The pulmonary flow velocity was significantly increased in the 180-s DCC group in terms of echocardiographic findings.

Abstract
OBJECTIVES The purpose of the study was to compare final pathology results with ultrasonography (USI) and fine needle aspiration biopsy (FNAB) results in parotis masses. METHODS A total of 123 patients with primary parotis mass who applied to our center between 2010 and 2020 were selected for the study. Among these, 100 patients with preoperative USI, preoperative FNAB, and postoperative final pathology were included in the study. USI, FNAB, pathology results, surgery types, and demographic characteristics of the patients were analyzed. RESULTS According to the postoperative final pathology, preoperative USI sensitivity was found to be 100%, specificity was 55, positive predictive value was 84.31%, negative predictive value was 100%, and accuracy was 86.89%. Preoperative FNAB had a sensitivity of 85.7%, a specificity of 92.1%, a positive predictive value of 82.1%, a negative predictive value of 90.2%, and a diagnostic accuracy of 89.3%, according to the postoperative final pathology. CONCLUSION Preoperative USI and preoperative FNAB are very valuable diagnostic tools in the evaluation of parotis lesions. When used together, they provide highly accurate and important data for the surgeon.

Abstract
Fabry disease (FD) is an X-linked, lysosomal glycosphingolipid storage disorder that occurs very rarely. Cardiac involvement may comprise of left ventricular hypertrophy (LVH), arrhythmias, conduction abnormalities, heart failure and valvular abnormalities. The goal of this study was to conduct gene analysis for FD in patients suffering from unexplained LVH. 120 patients over the age of 30 who were diagnosed by echocardiography with idiopathic LVH were included in the study. Patients with severe hypertension, intermediate valve disease such as moderate aortic stenosis, known FD, and a family history of autosomal dominant hypertrophic cardiomyopathy were excluded from the study. GLA gene mutations were studied by Sanger sequence analysis in all patients. Of the 120 total patients included in this study, 69 were female (58%) and 51 were male (42%). The mean age was 60.3 ± 15.7. GLA gene mutations were detected in three male patients. The detected mutations are as follows: NM_000169.2:IVS6-10G>A (c.1000-10G>A), NM_000169.2:c.937G>T (p.D313Y) (p.Asp313Tyr) and NM_000169.2:c.941A>T (p.K314M) (p.Lys314Met). Early diagnosis is of vital importance in FD, which can be treated with enzyme replacement. Genetic screening in patients diagnosed with idiopathic LVH by echocardiography is important in the early diagnosis and treatment of FD. Patients over 30 years of age with idiopathic LVH should be screened for FD. Various new polymorphisms can be detected in genetic screening. Identifying new polymorphisms is important for knowing the true mutations in FD.

Abstract
AIM To determine the predictive ability of serum thiol-disulphide levels for contrast medium-associated acute kidney injury (CA-AKI) after endovascular treatment (EVT) of peripheral arterial disease (PAD) and evaluate the efficacy of intravenous N-acetylcysteine (NAC) in preventing CA-AKI. MATERIAL AND METHODS This double-blind, randomised controlled study included 85 consecutive adult patients who underwent EVT for PAD. Patients were divided into NAC negative (NAC-) and positive (NAC+) groups. While the NAC- group received only 500 ml saline, the NAC + group received 500 ml saline plus intravenous 600 mg NAC before the procedure. Intra- and intergroup patient characteristics, procedural details, preoperative thiol-disulphide levels, and ischaemia-modified albumin (IMA) levels were recorded. RESULTS There was a significant difference between NAC- and NAC + groups regarding native thiol, total thiol, disulphide/native thiol ratio (D/NT), and disulphide/total thiol ratio (D/TT). There was also a significant difference between the NAC- (33.3%) and NAC+ (13%) groups in CA-AKI development. Logistic regression analysis showed that the D/TT (OR 2.463) and D/NT (OR 2.121) were the most influential parameters for CA-AKI development. In the receiver operating characteristic (ROC) curve analysis, the sensitivity of native thiol to detect the development of CA-AKI was 89.1%. The negative predictive values of native thiol and total thiol were 95.6% and 94.1%, respectively. CONCLUSION The serum thiol-disulphide level can be used as a biomarker to detect CA-AKI development and reveal patients with a low risk for CA-AKI development before EVT of PAD. Furthermore, thiol-disulphide levels allow for the indirect quantitative monitoring of NAC. Preprocedural intravenous NAC administration significantly inhibits CA-AKI development.

Abstract
GH gene is one of the important genes that affect the productive and physiological traits in livestock. This study aimed to use a meta-analysis to determine the association of the GH gene with growth traits in cattle. Four different genetic models were used: dominant LL + LV versus VV, recessive LL versus LV + VV, complete over dominant LL+VV vs. LV and co-dominant LL vs. LV, LL vs. VV and LV vs. VV. The random-effect model was used in data analysis based on I2. Meta-analysis showed an effect of GH genotypes on the birth weight (BW) under the recessive (p<0.05) and complete over dominant (p<0.01) models. However, no association (p>0.05) was found under the dominant model. In terms of co-dominant model, the GH polymorphism showed a significant association with BW (SMD = 0.359, 95% CI = 0.119 to 0.599, p = 0.003) under LL vs. LV genotype combination patterns. No association was found between GH polymorphism and BW under LL vs. VV genotype combination. The results showed that the LL genotype had a significant effect on BW traits from LV and VV genotypes when comparing the models. The results showed an effect of the GH on ADG under four genetic models (p<0.05).

Abstract
INTRODUCTION Nipple-sparing mastectomy (NSM) with immediate breast reconstruction (IBR) is increasingly used for both breast cancer (TNSM) and risk reduction (RRNSM). The aim of the study is to report the results of the INSPIRE registry assessing health-related quality of life (HRQoL) comparing baseline and 1-year follow-up, regarding surgical indications and chemotherapy (CT) received. METHODS INSPIRE is a prospective database including women undergoing NSM and IBR from 18 countries. HRQoL was measured using EORTC QLQC30 and QLQ-BR23 before surgery and after 1 year. RESULTS A total of 677 women were included, of whom 537 (79.3%) underwent TNSM and 140 (21.6%) RRNSM: in total, 806 NSM (556 TNSM and 250 RRNSM). Nipple involvement was present in 7.73% of TNSM and incidental carcinoma in 1.2% of the RRNSM group. Out of the overall 537 patients with systemic treatment, 177 (32.96%) received neoadjuvant chemotherapy (NCT) and 118 (21.92%) adjuvant chemotherapy (CT). A total of 227 patients (28.16%) developed at least one complication postoperatively, 164 (29.5%) in the TNSM group and 63 (25.2%) in the RRNSM group. The TNSM group improved in global health status and emotional functioning after 1 year. No differences were found when comparing HRQoL at 1 year between patients who received NCT and those who received adjuvant CT. The RRNSM group showed improvement in HRQoL, with better emotional functioning and fatigue after 1 year. CONCLUSIONS This registry reports HRQoL findings after NSM. The impact of CT on worse HRQoL is independent from its timing. Patients with RRNSM showed an improved HRQoL at 1-year follow-up. Discussion of HRQoL outcomes with patients will facilitate the informed decision-making when considering NSM.

Abstract
BACKGROUND The most commonly used recording-side method in intraoperative neural monitoring (IONM) detects the stimulus with the endotracheal tube surface (ETS) electrodes placed in the endotracheal tube during thyroidectomy. The thyroid cartilage needle (TCN) electrode method is an alternative recording-side system in IONM. This study compared two recording-side techniques in IONM. METHODS Data were retrospectively analyzed from 885 patients who underwent thyroidectomy between January 2012 and December 2020, with 110 ETS and 775 TCN electrodes. Patients' demographics, diagnosis, surgery type, and amplitudes of all stimulation steps were compared. Costs per patient were calculated. RESULTS No significant differences were found in the demographic data between the two groups. All amplitudes were higher in the IONM system where TCN electrodes were used than that with ETS electrodes (all stimulation steps p < 0.001, except left-V2 p = 0.007). Further, TCN electrodes were 20 times cheaper than the ETS electrodes. CONCLUSION TCN electrodes are an inexpensive and efficient alternative to ETS electrodes in IONM.

Abstract
PURPOSE In this study, we aimed to assess the effectiveness of malignancy stratification algorithms of the American College of Radiology (ACR) and European Thyroid Association (ETA) in the delineation of thyroid nodules using a database of nodules that were unequivocally diagnosed by means of histopathological examination and meticulously matched with the imaged nodules. METHODS A total of 165 patients having 251 thyroid nodules with histopathologically proven definitive diagnoses during a 5-year period were included in this study. All patients had preoperatively undergone ultrasonography (US) examination, and US characteristics of the thyroid nodules were retrospectively analyzed and assigned in compliance with the thyroid imaging reporting and data system categories recommended by the ACR (ACR-TIRADS) and ETA (EU-TIRADS). The diagnostic effectiveness in the delineation of thyroid nodules and unnecessary fine-needle aspiration (FNAB) rates were evaluated. RESULTS Overall, 189 nodules (75.30%) were diagnosed as benign, while 62 nodules (24.70%) were reported to be malignant based on histopathological assessment. Sensitivity and specificity rates were 71% and 75% for ACR-TIRADS and 73% and 80% for EU-TIRADS. The area under the curve values were 0.78 and 0.80 for ACR-TIRADS and EU-TIRADS, respectively. The unnecessary FNAB rates were 61% for ACR-TIRADS and 64% for EU-TIRADS as per the recommended criteria of each algorithm. CONCLUSION The diagnostic performance of both malignancy stratification systems was signified to be moderate and sufficient in a cohort of nodules with definite histopathological diagnosis. In light of our results, we demonstrated the strengths and weaknesses of the ACR- and EU-TIRADS for physicians who should be familiar with them for optimal management of thyroid nodules.

Abstract
The present study aims to examine the extent to which adolescents of immigrant background experience acculturative stress (i.e., cultural clashes with parents and ethnic victimization in school) in multiple contexts, and the reasons why such stress takes a toll on their psychological functioning and views of themselves. The analytic sample includes adolescents of immigrant background residing in Sweden (N = 423, Mage = 13.19, SD = 0.51). Cluster analysis revealed five distinct groups of adolescents, based on their reports of cultural clashes with parents and ethnic victimization in school: (1) low on both acculturative stressors, (2) average on both acculturative stressors, (3) high on cultural clashes only, (4) high on ethnic victimization only, and (5) high on both acculturative stressors. Mediation analysis showed that adolescents who experienced cultural clashes at home and who were also victimized by their peers in school reported higher levels of feeling in between cultures than adolescents in all the other clusters (except those high on cultural clashes only), and in turn reported higher levels of depressive symptoms and lower levels of self-esteem. The present study highlights the importance of understanding immigrant youth's experiences across multiple contexts simultaneously in order to develop a holistic perspective on their adjustment and integration processes.

Abstract
BACKGROUND The interest in the morphological development of brain structures during childhood and adolescence arises from discussions on subcortical anomalies and sexual dimorphism, from adolescent changes in cognitive functions supported by cortical and subcortical structures to a wide range of childhood neuropsychiatric diseases. This study aims to investigate the relationships subcortical structures regarding age/gender changes in the healthy adult human brain using web-based VolBrain. MATERIALS AND METHODS In this study, 303 normal healthy adults [male and female] were obtained using a 1.5 T unit with a 20-channel head coil. RESULTS The volumes of White Matter, Gray Matter, Total Brain, Cerebrospinal Fluid, and Total Intracranial Volume were significantly higher in males than those in females. Our analysis revealed a significantly larger accumbens volume for females. With age less than or equal to 50 years, older males were found to have higher total LV, putamen, thalamus, amygdala, cerebrum, White Matter and Gray Matter volumes than females. The age greater than the 50-years-old group resulted in a mean of total thalamus, Globus Pallidus and accumbens volumes higher in females than those in males. Right hemisphere volumes in younger and older age groups resulted in volumes except caudate in the older age group; the mean of caudate was significantly higher in females than those in males. CONCLUSIONS These conclusions might have important for the explanation of the effects of gender and age in cross-sectional structural MRI studies. Also, knowing the volume changes of the subcortical structures can provide convenience about the prevention, diagnosis, and treatment of various neuromental disorders.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic, relapsing and debilitating inflammatory disease associated with profound morbidity. AIM In this multicentre study, we investigated the demographic and clinical features of HS, and determined risk factors of disease severity. METHODS In total, 1221 patients diagnosed with HS from 29 centres were enrolled, and the medical records of each patient were reviewed. RESULTS The mean age of disease onset was 26.2 ± 10.4 years, and almost 70% (n = 849) of patients were current or former smokers. Mean disease duration was 8.9 ± 8.4 years with a delay in diagnosis of 5.8 ± 3.91 years. Just over a fifth (21%; n = 256) of patients had a family history of HS. The axillary, genital and neck regions were more frequently affected in men than in women, and the inframammary region was more frequently affected in women than in men (P < 0.05 for all). Acne (40.8%), pilonidal sinus (23.6%) and diabetes mellitus (12.6%) were the most prevalent associated diseases. Of the various therapies used, antibiotics (76.4%) were most common followed by retinoids (41.7%), surgical interventions (32.0%) and biologic agents (15.4%). Logistic regression analysis revealed that the most important determinants of disease severity were male sex (OR = 2.21) and involvement of the genitals (OR = 3.39) and inguinal region (OR = 2.25). More severe disease was associated with comorbidity, longer disease duration, longer diagnosis delay and a higher number of smoking pack-years. CONCLUSIONS Our nationwide cohort study found demographic and clinical variation in HS, which may help broaden the understanding of HS and factors associated with disease severity.

Abstract
The ectopic spleen (ES) is a rare variation occurred depend on the absence or laxity of the suspensory ligaments. The ES is a rarely diagnosed clinical condition. Less than 500 symptomatic patients have been reported. Less than 0.25% of splenectomies are performed on the ES. Patients are usually asymptomatic. It's diagnosed incidentally in general. The incidence is not clear. ES incidence is reported less than 0.5%. However, this rate covers all of the relocations. The spleen can be found anywhere in the abdomen or pelvis, depends on the length of the vascular pedicle. The pelvic ES is a rarely encountered situation. Knowing this anomaly is essential for early diagnosis and prevention serious problems such as torsion, infarction and acute abdomen. A 21 years old female patient with ES was presented on pelvic magnetic resonance imaging.

Abstract
OBJECTIVE Almost all countries announced social restrictions and distancing measures which could unintentionally lead to a decline in admissions to hospital for acute disorders other than signs of pneumonia. We aimed to evaluate lipid profile, neutrophil to lymphocyte ratio (NLR) and cardiovascular admissions to the coronary care unit (CCU) of a tertiary center in Turkey during the COVID-19 era and to compare these results with admissions in the same time interval of the previous year. MATERIALS AND METHODS We retrospectively analyzed CCU admissions due to new-onset atrial fibrillation, ST-elevation myocardial infarction, non-ST elevation acute coronary syndrome (NSTEACS) and acute heart failure during the COVID-19 outbreak and the same time interval of the past year. Laboratory measurements including lipid profile and NLR values were retrieved from the institutional digital database. RESULTS Compared to the same time interval of 2019 (March-April, 2019), the number of patients admitted to the CCU with acute cardiovascular disorders (atrial fibrillation, STEMI, NSTEACS and acute heart failure) were lower in the COVID-19 period. The levels of NLR, total cholesterol, and low-density lipoprotein (LDL) cholesterol were significantly higher and high-density lipoprotein (HDL) cholesterol was significantly lower in subjects admitted to the CCU during March-April 2020 compared to subjects admitted in March-April 2019. CONCLUSIONS Our findings show that subjects admitted to the CCU in the COVID-19 era have an unfavorable lipid profile and elevated NLR compared to those admitted in 2019. These patients appear to be at high risk for future cardiovascular events.

Abstract
Knowledge of imaging findings related to therapy administered to patients with sarcoma is pivotal in selecting appropriate care for these patients. Imaging studies are performed as surveillance in asymptomatic patients or because symptoms, including anxiety, develop. In addition to detection of recurrent disease and assessment of response to therapy, diagnosis of conditions related to therapy that may or may not need treatment has a marked positive impact on quality of life. The purpose of this review is to assist radiologists, nuclear physicians, and others clinicians involved in the diagnosis and treatment of these patients in recognizing imaging findings related to therapy and not to activity of the previously treated sarcoma. Imaging findings are time dependent and often specific in relation to therapy given.

Abstract
Objective: There has been no previous study comparing the frequency of sicca symptoms and Sjögren's syndrome (SS) in coeliac patients (CPs) and healthy controls (HCs) using a tight screening method. The aim of this study was to compare the frequency of sicca symptoms and SS in HCs and CPs.Method: The study included 80 CPs and 100 HCs. This study was designed as a case-control study with four phases. The frequency of SS in CPs and HCs was defined according to the 2002 American-European Consensus Group (AECG) and 2012 American College of Rheumatology (ACR) classification criteria. The frequency of sicca symptoms and SS was compared between CPs and HCs.Results: Ocular and oral symptoms occurred in 22% and 26% of CPs, respectively, compared to 13% and 10% of HCs, respectively. Proportions with oral symptoms were statistically significantly different between CPs and HCs (p = 0.005), whereas there was no significant difference for ocular symptoms (p = 0.113). According to ACR and AECG criteria, the prevalence of SS was 3.8% and 5.0% in CPs and 3.0% and 2.0% in HCs, respectively.Conclusion: Although oral symptoms were more frequent in CPs than in HCs, the frequency of SS was not different between the groups. The increased frequency of oral symptoms may be related to reasons other than autoimmunity.

Abstract
Objectives The incidence of papillary microcarcinomas, which are defined as thyroid cancers of <10mm in size, has been increasing in the last decade. Herein, we present internet-based questionnaire results performed by the Turkish Association of Endocrine Surgery with the aim to evaluate the perspective of the management of papillary microcarcinomas in Turkey. Material and Methods The user-friendly questionnaire consisted of 13 questions in total. These questions mainly addressed the surgical management of nodules and cancer of <1 cm in size. Patient management before, during, and after surgical intervention was also included; additionally, the "active surveillance approach" was questioned. Results There were 420 responders in total who were of multidisciplinary origin (endocrinologists, surgeons, nuclear medicine specialists, pathologists, and oncologists). Total thyroidectomy was the predominant treatment approach (65%) for the classical type of microcarcinoma limited in one lobe, whereas in cases of microcarcinomas incidentally diagnosed during hemithyroidectomy, complementary surgery approach was advised by 40% of the responders. The responders found capsule invasion (86%) and patient based management (94%) of high importance. The percentage of the responders who recommended radioactive iodine ablation in incidental cancers having no aggressive criteria was 51%. The survey participants that were against routine central dissection in these cases accounted for 73% of the responders. The recommendation of active surveillance (follow-up without any interventional therapy) was limited with 9% responders. Conclusion The results of the questionnaire demonstrated that there have been various choices in Turkey for the surgical treatment of the papillary microcarcinomas.

Abstract
OBJECTIVE The goal of this study was to define clinical practice patterns for assessing stroke and bleeding risks and thromboprophylaxis in nonvalvular atrial fibrillation (NVAF) and to evaluate treatment outcomes and patient quality of life. METHODS A clinical surveillance study was conducted in 10 tertiary healthcare centers across Turkey. Therapeutic approaches and persistence with initial treatment were recorded at baseline, the 6th month, and the 12th month in NVAF patients. RESULTS Of 210 patients (57.1% male; mean age: 64.86±12.87 years), follow-up data were collected for 146 patients through phone interviews at the 6th month and 140 patients at the 12th month. At baseline, most patients had high CHADS2 score (≥2: 48.3%) and CHA2DS2-VASc (≥2: 78.7%) risk scores but a low HAS-BLED (0-2: 83.1%) score. Approximately two-thirds of the patients surveyed were using oral anticoagulants as an antithrombotic and one-third were using antiplatelet agents. The rate of persistence with initial treatment was approximately 86%. Bleeding was reported by 22.6% and 25.0% of patients at the 6th and 12th month, respectively. The proportion of patients with an INR of 2.0-3.0 was 41.8% at baseline, 65.7% at the 6th month, and 65.9% at the 12th month. The time in therapeutic range was 61.0% during 1 year of follow-up. The median EuroQol 5-dimensional health questionnaire (EQ-5D) score of the patients at baseline and the 12th month was 0.827 and 0.778, respectively (p<0.001). The results indicated that patient quality of life declined over time. CONCLUSION In atrial fibrillation, despite a high rate of persistence with initial treatment, the outcomes of stroke prevention and patient quality of life are not at the desired level. National health policies should be developed and implemented to better integrate international guidelines for the management of NVAF into clinical practice.

Abstract
Oncocytic neoplasms of the adrenal gland are extremely rare tumors. These tumors differ from their nononcocytic counterparts in some respects. The aim of this study was to review and discuss the clinical, histological, and immunohistochemical features of as well as the prognosis for these rare tumors. In total, 16 cases diagnosed as adrenocortical oncocytic neoplasms between January 2011 and December 2016 were included in the study. The demographic data, gross characteristics, histological data, and immunohistochemical data (Chromogranin-A, Synaptophysin, α-Inhibin, Melan-A, Ki67, PHH3) were reevaluated. The follow-up data for these patients were added in January 2017. Of the 16 cases, 12 were adrenocortical adenoma, 1 was borderline adrenocortical tumor, and 3 were adrenocortical carcinoma. The tumors equally affected both genders. The tumors were not generally large. Tumor cells had pleomorphic nuclei in ten cases, but it was more obvious in one case. The mitotic figure count was low in most tumors. Atypical mitosis and necrosis were observed in three and four tumors, respectively. None of cases included sinusoidal invasion, vascular invasion, or capsular invasion. We detected the expression of at least one specific marker (e.g., Melan-A, Inhibin-α) of the adrenal cortex in all tumors. None of the tumors were immunoreactive for Chromogranin-A. Ki-67 proliferation index was lower than 5% in all cases except three oncocytic carcinomas. In two cases, PHH3 positivity was not seen, while it was lower than 3 of 10 high-powered fields in ten cases and higher in 4 cases. All patients were alive and disease free except for two patients with adrenocortical carcinoma. In conclusion, determining the clinical, histological, and immunohistochemical characteristics of these extremely rare tumors can provide important information for early diagnosis, treatment, and follow-up of these cases.

Abstract
Ectopic parathyroid glands can be located at any anatomical location from the base of the tongue to the mediastinum. One-third of these glands migrate deep into the mediastinum, which are not accessible with a low cervical incision. In this article, we described the robotic approach to an ectopic mediastinal parathyroid gland. This management method of mediastinal adenomas has significant advantages when compared to conventional surgery.

Abstract
Objectives To determine the substance abuse profiles of patients treated a Drug Addiction Research, Treatment, and Education Center (AMATEM) in association with the percentage of substance use distribution and multiple substance use in their urine samples. For this, we retrospectively evaluated the urine sample analysis reports of 600 male and female patients aged 13 to 65 years who were treated at the AMATEM unit of İstanbul Neuropsychiatry Hospital between January 1st, 2015, and December 12th, 2015. Materials and Methods The urine samples were sent to Üsküdar University Advanced Toxicology Analysis Laboratory and were analyzed using a UPLC tandem mass spectrometer (UPLC-MS/MS). To determine the substance use profiles of the patients applying to AMATEM, statistical assessment was performed on the analysis reports of the patients. Results When the analysis reports of the 600 urine samples were examined, 293 patients were identified to have used addictive substances. The substances most frequently detected in the urine samples were respectively: cannabis, alcohol, morphine, cocaine, synthetic cannabinoids, 3,4-Methylenedioxymethamphetamine, and amphetamine. Conclusion The findings in our study resemble the rates of cannabis use by the young population throughout the world. Our results show differences to the literature regarding the consumption of synthetic cannabinoids because the variety of synthetic cannabinoids change rapidly around the world each year.

Abstract
OBJECTIVES Methemoglobinemia (MetHb) is a rare condition that may have mortal consequences. Literature shows cases of methemoglobinemia due to the use of lidocaine and other local anesthetics. This is a cross-sectional study to determine the incidence of methemoglobinemia after the application of lidocaine. METHODS In this study, 88 patients admitted to the emergency department of a university hospital between May 2014 and May 2015 and needed lidocaine application for small surgical procedures were included. When compared before and after the administration of lidocaine <2 mg/kg and >2 mg/kg, there was not a significant difference in the level of methemoglobin, hemoglobin, or in the hematocrit (p=0.604, p=0.502, and p=0.367, respectively). RESULTS Mean age of the patients was 33.85 (±17.58) years, and 83% of the patients were male. Methemoglobin levels were not significantly different before and after the procedures (p>0.05). CONCLUSION The results of our study were consistent with the literature; lidocaine associated methemoglobinemia is a rare complication.

Abstract
The approach to patients with an indication for oral anticoagulation (OAC) for atrial fibrillation (AF) who undergo coronary stenting and thus need dual antiplatelet therapy has long been debated. Dual antiplatelet therapy accompanied by OAC (so called "triple therapy") carries a high bleeding risk and thus should either be avoided or used for a limited period. The lack of relevant prospective randomised trial data have largely been overcome by the recently published PIONEER AF-PCI trial, the results of which will be summarized in this article.

Abstract
Background Pneumocephalus and pneumorrhachis are rare complications of neurosurgery. When a closed system such as the head and spinal area get injuried, it becomes open and the air can come in through that opening. In this case, we present a case of pneumocephalus and pneumorrhachis after spinal fusion surgery. Case Report Herein we present a case of diagnosis and treatment of pneumocephalus and pneumorrhachis after spinal fusion surgery. Conclusions Our patient developed postoperative pneumocephalus and pneumorrhachis as a late complication secondary to an infection. We wanted it to be considered as an important problem.

Abstract
BACKGROUND Clinical and epidemiological data well defines the role of atherosclerotic risk factors in pathogenesis of aortic stenosis. Especially dyslipidemia with elevated total and LDL cholesterol levels exerts certain histopathological changes on calcified valve tissue. Exact role of HDL in this process is not known. OBJECTIVE To evaluate the lipid profiles of patients with mild aortic valve stenosis with special focus on HDL; HDL subspecies, serum apoA1 levels, HDL related PON1 and PAF-AH enzyme activities and to correlate this with disease progression rates. METHOD 42 patients (26 female; 16 male), with calcific aortic valve stenosis were enrolled in the study. Serum fasting lipid parameters, HDL subspecies (HDL2, HDL3), serum apoA1 levels and HDL related PON1 and PAF-AH enzyme activities were determined. All participants underwent detailed follow-up transthoracic echocardiography examination. RESULTS Among 42 study participants mean serum total cholesterol level was 195 ± 27.3 mg/dl, LDL-c level was 123 ± 19.1 mg/dl, HDL-c level was 44 ± 10.3 mg/dl and total cholesterol/HDL-c ratio was 4.64 ± 1.13. Basal peak aortic jet velocity (Vmax2) was 2.67 ± 0.39 m/sec, mean pressure gradient (Pmean2) was 15.6 ± 5.5 mmhg. Annual progression rate in peak aortic jet velocity (Vmax) was 0.23 ± 0.17 m/sec, in mean pressure gradient (Pmean) was 3 ± 2.1 mmhg. Annual progression rate in Pmean was most strongly correlated with serum HDL-c level and total/HDL-c ratio (r=-0.528 and 0.505; <0.001 and 0.001 respectively). Progression in Vmax values was positively correlated with serum LDL-c level and total/HDL-c ratio while negatively correlated with serum HDL-c levels (r=0.328, 0.499 and -0.464; P=0.034, 0.001 and 0.002 respectively). Among HDL subspecies HDL2 was the predominant type. HDL2 levels were found to be positively correlated with progression rates. There was no significant correlation between apolipoprotein A1 level and annual progression rate. Serum PON1 activity level was determined to be negatively correlated to doppler echocardiographic progression parameters while HDL related PAF-AH activity was independent of disease progression. CONCLUSION Present study demonstrated a positive correlation between disease progression and serum total cholesterol/HDL-c ratio. Serum HDL-c level was inversely correlated with hemodynamic progression. The majority of HDL was HDL2 subtype. Among HDL related enzymes PON1 enzyme activity exhibited an inverse correlation with disease progression.

Abstract
Sensory evaluation is a critical process in product development and consumer research. It is a fastly growing field due to innovation of novel techniques. The objective of this study was determination of sensory properties of red raspberry extract in fruity flavoured beverages comparison to the synthetic preservatives. For this purpose, an organoleptic stability study on fruity flavoured beverages was conducted storing them at several temperatures (room temperature, 2 ± 2 °C and 40 ± 2 °C) in the dark for 3 months. Sensory quality of beverages was analysed. Difference in pH and data obtained from °Brix measurements during storage was evaluated statistically. Room temperature and 40 ± 2 °C were detected to affect sensory characteristics of beverages. Highest variations were observed at 40 ± 2 °C. Beverages stored at 2 ± 2 °C displayed most acceptable appearance in organoleptic evaluation and insignificant change occured. It was also found that red raspberry extract provided stable sensory effects, color, flavour and taste, in beverages compared to synthetic preservatives at 2 ± 2 °C.

Abstract
BACKGROUND AND OBJECTIVES To assess the relevance of Parvovirus B19 (B19V) DNA at low to intermediate concentrations in blood donors for the recipients of their blood components. MATERIAL AND METHODS We studied recipients of B19V DNA-positive blood components [red blood cell concentrates (RBCs), pooled platelet concentrates and fresh frozen plasma]. This included archived pretransfusion samples as well as follow-up samples investigated by ELISA or NAT and genome sequence analysis. RESULTS In 132 out of 424 recipients, we could detect no anti-B19V IgG before transfusion. In 67 out of 132 sero-negative recipients, a follow-up sample was available. Sixty-five of these received blood components from donors with <10(4) IU B19V DNA/ml plasma and had no evidence of transfusion-transmitted (TT)-B19V infection. Homology in genome sequences in donor and recipient provided evidence for a TT-B19V infection in two recipients. Both patients received RBC containing 3.4 × 10(6) and 1.8 × 10(4) IU B19V DNA/ml plasma, respectively. The anti-B19V IgG titres in the donors were 2 and 76 IU/ml plasma, respectively. The antibodies in the second donor were directed against capsid proteins and are thus considered as potential neutralizing antibodies. CONCLUSIONS TT-B19V infections through blood components with low (<10(4) IU/ml plasma) B19V DNA concentrations did not occur in our study. One of the TT-B19V infections occurred from RBC with intermediate B19V DNA concentration despite the presence of potential neutralizing antibodies in the donor, but its clinical significance was low.

Abstract
Paranasal mucoceles are benign slow-growing paranasal sinus lesions, which usually develop following the obstruction of the sinus ostiu. They most frequently occur in the frontal sinus. Frontal mucoceles are expansive lesions usually causing visual clinical signs and symptoms such as diminution of vision, visual field defects, diplopia, orbital swelling, retroorbital pain, displacement of eye globe, ptosis, and proptosis. When the frontal mucocele extends intracranially, it can manifest with meningitis, meningoencephalitis, intracranial abscess, seizures, or cerebrospinal fluid fistula. Very rarely it can cause forehead swelling. We report an 80-year-old woman presenting with a forehead skin ulcer and painless subcutaneous forehead induration. Histopathologic examination revealed mucin deposition and inflammation. Computerized tomography (CT) and magnetic resonance imaging (MRI) scans showed a mass originating from the frontal sinus with frontal bony defect and frontocutaneous fistula. Surgical excision of the mass confirmed the mucocele diagnosis. In this article, we present a case of frontocutaneous fistula and skin ulcer, which is an unexpected complication of frontal mucocele. We propose that in the case of a localized non-healing ulcerated forehead skin lesions, mucocele should be considered in the differential diagnosis.

Abstract
The aim of this study is to investigate the histopathological findings of drill hole healing and interactions of parathyroid hormone (PTH), β-catenin and transcription factor-4 (TCF7L2/Tcf-4) after local application of recombinant human bone morphogenic protein-2 (rhBMP-2). Sprague Dawley rats were used in two groups of ‘femoral cortex hole model’. In the non-treated group, a hole was opened with a 3 mm K-wire in the distal and mid third junction of the right femur. In the treated group, local rhBMP-2 protein was injected into the similar femoral hole. Sterile 18M H2O was injected into the femoral hole at contralateral femur. There was more subperiosteal membranous bone reaction in the group treated with rhBMP-2 injection compared to the non-treated group. This was also proven immunohistochemically in both ipsilateral and contralateral femur with increased anti bone morphogenic protein-2 (anti BMP-2) expression. Moreover, there was an increased subperiosteal reaction at the contralateral femur. Also, in the treated group, PTH expression was increased in cells that form callus, and nuclear beta-catenin expression was increased in chondrocytes of periosteal ossification. Future studies should try to find whether the effects of rhBMP-2 on PTH and Wnt signaling pathway changes with different fracture models, also the systemic effects of local rhBMP-2 application should be investigated.
