Item Acute-Phase Stroke Outcome and Lipids(2021) Kaya, Ahmet; 35317377Objectives: The aim of the study is to investigate the relationship of lipid subgroups with short-term mortality in acute stroke (AS). Methods: This retrospective study included 698 patients with AS who presented within 24 h of symptom onset. A hemogram from peripheral venous blood samples was taken at admission. Total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low- density lipoprotein cholesterol (LDL- C), TC/HDL-C rate, and TG/HDL-C rate were recorded. Duration of follow-up was defined as 30 days. Results: 64 out of 698 patients died during the follow-up period. The mean TG, TG/HDL-C, and TC/HDL-C levels were significantly lower in the mortality group than the survival group. In the receiver operating characteristic (ROC) analysis, the cutoff values and area under the curve of the TG, TG/HDL-C, TC, and TC/HDL- C levels for short-term stroke mortality are as follows ([100.2 mg/dL, 0.648]; [2.52, 0.650]; [170.50 mg/dL, 0.598]; and [4.32, 0.640], respectively). In the Cox regression model, only TG and TG/HDL-C, according to their ROC cutoff values, were independent variables as short-term mortality predictors ( TG =100.2 mg/dL, HR:2.413, 95% CI: 1.345-4.327, P:0.004); ( TG/HDL =2.56, HR: 2.720, 95% CI: 1.389-5.359, P:0.003, respectively). Conclusion: Dyslipidemia is a well-known as a risk factor of stroke. However, this study focused on the estimation that lower TG and TG/HDL-C levels at the time of hospital admission might be predictors of short-term mortality within a month of AS attack, which is a different subject from long term risk factors of stroke. Serum TG level may be a better indicator for mortality in the acute hypercatabolic trauma such as stroke.Item An add-on therapy for neuropathic pain: Infiltration block with diclofenac sodium and lidocaine through the hypertrophic scar tissue(2019) Eker, Hatice Evren; Yalcin Cok, Oya; Bozdodan Ozyilkan, Nesrin; Aribodan, Anis; 30633313In some situations, the cause of the supposed neuropathic pain might be related to abnormal tissue recovery such as scar formation due to wound retraction that might create mechanical compression on the nerve tissue. In this report we describe infiltration block with diclofenac sodium and lidocaine through the hypertrophic scar tissue to reduce mechanical stress in 3 patients. The infiltration technique might resolve the tension of the contracted scar tissue by tearing the adhesions and the eliminated mechanical compression would reduce the pressure on nerve tissue and hence neuropathic pain symptoms.Item Adding stewed apricot juice to senna improves quality of colon cleansing in preparation for colonoscopy(2017) Yasar, Bulent; Abut, Even; Kayadibi, Huseyin; Akdogan, Fatih; Gonen, CanBackground: To achieve optimal colonoscopic examination, the bowel must be sufficiently cleansed. However, none of the currently available colonoscopy preparation regimens is safe, efficient, and comfortable. The aim of this study was to determine whether adding stewed apricot juice to senna increased patient comfort and improved bowel cleansing during colonoscopy preparation. Methods: Outpatients of both genders who were over 18 years old and were referred for elective colonoscopy were randomly allocated to drink stewed apricot juice with senna or senna by itself. The quality of the colon cleansing was evaluated using the Ottawa scale. Patient tolerance and adverse events were evaluated through the completion of a questionnaire. Results: The study included a total of 128 patients in the randomization procedure. A significantly greater cleansing effect was observed using stewed apricot juice plus senna in the right and transverse colon (p = 0.038, p = 0.037 respectively). It was also determined that in the stewed apricot juice plus senna group, overall cleansing was superior (p < 0.001), total colonoscopy (17.6 min vs. 22.8 min, p = 0.048) and cecal intubation (7.4 min vs. 11.2 min, p = 0.042) times were shorter, and the colonoscopy procedure was easier (79.4% vs. 49.2%, p < 0.001). No differences were observed between the groups with respect to patient acceptance, compliance, and adverse events. In the stewed apricot juice plus senna group, 91.2% of patients stated their willingness to receive the same regimen in the future compared to 80% of the patients in the senna alone group (p = 0.037). Conclusion: The addition of natural, stewed apricot juice to senna significantly improves cleansing outcomes without additional adverse effects.Item Addition of gonadotropin releasing hormone agonist for luteal phase support in in-vitro fertilization: an analysis of 2739 cycles(2015) Simsek, Erhan; Kilicdag, Esra Bulgan; Aytac, Pinar Caglar; Coban, Gonca; Simsek, Seda Yüksel; Cok, Tayfun; Haydardedeoglu, Bulent; 26097392Objective: Luteal phase is defective in in vitro fertilization (IVF) cycles, and many regimens were tried for the very best luteal phase support (LPS). Gonadotropin releasing hormone (GnRH) agonist use, which was administered as an adjunct to the luteal phase support in IVF cycles, was suggested to improve pregnancy outcome measures in certain randomized studies. We analyzed the effects of addition of GnRH agonist to standard progesterone luteal support on pregnancy outcome measures, particularly the live birth rates. Material and Methods: This is a retrospective cohort study, including 2739 IVF cycles. Long GnRH agonist and antagonist stimulation IVF cycles with cleavage-stage embryo transfer were included. Cycles were divided into two groups: Group A included cycles with single-dose GnRH agonist plus progesterone LPS and Group B included progesterone only LPS. Live birth rates were the primary outcome measures of the analysis. Miscarriage rates and multiple pregnancy rates were the secondary outcome measures. Results: Live birth rates were not statistically different in GnRH agonist plus progesterone (Group A) and progesterone only (Group B) groups in both the long agonist and antagonist stimulation arms (40.8%/41.2% and 32.8%/34.4%, p<0.05 respectively). Moreover, pregnancy rates, implantation rates, and miscarriage rates were found to be similar between groups. Multiple pregnancy rates in antagonist cycles were significantly higher in Group A than those in Group B (12.0% and 6.9%, respectively). Conclusion: A beneficial effect of a single dose of GnRH agonist administration as a luteal phase supporting agent is yet to be determined because of the wide heterogeneity of data present in literature. Well-designed randomized clinical studies are required to clarify any effect of luteal GnRH agonist addition on pregnancy outcome measures with different doses, timing, and administration routes of GnRH agonists.Item Adenovirus-36 Infection and Obesity: A Case Control Study of Turkish Women with Polycystic Ovary Syndrome(2021) Cakmakliogullari, Elcin Kal; Eroglu, Semra; 0000-0002-9959-9433; 33581595Background and aims: Adenovirus-36 (Ad-36) seropositivity has been shown to be involved in the aetiology of obesity. The aim of this study was to examine Ad-36 positivity in obese and normal-weight patients with polycystic ovary syndrome (PCOS). Methods: There were two groups including 92 and 110 subjects. This study was a prospective casecontrol study. The enzyme-immunoassay method was used to quantitatively determine antibodies (Abs) specific to human Ad-36 in the serum samples. Age, body mass index (BMI), fasting glucose levels and insulin levels of the participants were recorded. The PCOS and control group patients were divided into two groups: the overweight group with BMI >= 25 kg/m(2) and non-obese group with BMI <25 kg/m(2). Results: Ad-36 Ab positivity in the PCOS group was found to be significantly higher than that in the control group (p < 0.001). Ad-36 Ab positivity was significantly higher in the PCOS obese group than in the control obese group (p < 0.001). Ad-36 Ab positivity and BMI >= 25 kg/m(2) were identified as independent predictors of PCOS in logistic regression analysis. Conclusion: Ad-36 Ab positivity was significantly higher in the obese/overweight PCOS patients. Obesity can be prevented in patients with PCOS by treating Ad-36. (C) 2021 Diabetes India.

The current IE guidelines recommend antibiotic prophylaxis only in patients with certain cardiac conditions and before certain dental procedures. However, there is not enough data about solid organ transplant (SOT) recipients. In this study, we aimed to investigate the IE prophylaxis in general dental and periodontal surgical procedures among our SOT recipients. Medical records of 191 SOT recipients (32 liver transplant recipients, 54 heart transplant recipients, and 105 kidney transplant recipients) who were admitted to our hospital between January 2016 and January 2018 were evaluated. A total of 65 patients who underwent dental procedures were included in the study. We investigated the adequacy of IE prophylaxis according to the current guidelines. Two groups were created according to whether they received antibiotic prophylaxis or not. The mean age was 44.2 +/- 13.6 years, and 66.1% were male. The majority of patients (67.6%) received antibiotic prophylaxis. The most commonly used antibiotic was amoxicillin (48.8%). Among the procedures, 23.1% were classified as invasive and 76.9% were classified as noninvasive. No complication was observed after invasive and noninvasive dental procedures. There were no complications in both antibiotic prophylaxis and no-prophylaxis groups. According to our results, IE prophylaxis has been used appropriately in SOT recipients in our center. No serious infection has been reported. In addition, no complication due to antibiotic use was also observed.Item Adequacy of Physicians Knowledge Level of Cardiopulmonary Resuscitation to Current Guidelines(2015) Gulsum, Kocalar Ummu; Deniz, Arslan Engin; Cemil, Kavalci; Kayipmaz, Afsin Emre; Gulsum, Kavalci; Sukru, Yorulmaz; Akin, Giray TufanAim: The purpose of this study is to test the level of information on CPR and suitability to current application of the phsicians practicing in hospital ANEAH. Material and Method: The form of a test of 20 questions fort his purpose has been prepared in accordance with the 2010 AHA-ERC CPR guidelines. This form distributed to volunteer physicians to fill in. A total of 173 physicians agreed to participate in he study. The results were analyzed statistically and tried to determine the factors affecting the level of information. Results:According to the results of the study physicians gender, age and the total duration of physicians and medical asistance doesn't affect the level of information. The number of CPR within I month positively affect the level of knowledge. The number of theoretical and practical training in medical school, have taken the positive impact the level of knowledge of physicians. The training period after graduation, significantly increased the level of physicians information, The order of these training sessions with the asistant courses, congress, seminars and lessions on the sempozims are effective. Discussion: CPR trainig programs for physicians should be standardized, updated and expanded. Recurent in-service trainig should be provided to increase phsicians knowledge on skills.Item Adherence to guideline-directed medical and device Therapy in outpAtients with heart failure with reduced ejection fraction: The ATA study(2020) Kocabas, Umut; Sariturk, Cagla; Altay, Hakan; Pehlivanoglu, Seckin; 32628147; AAE-1392-2021Objective: Despite recommendations from heart failure guidelines on the use of pharmacologic and device therapy in patients with heart failure with reduced ejection fraction (HFrEF), important inconsistencies in guideline adherence persist in practice. The aim of this study was to assess adherence to guideline-directed medical and device therapy for the treatment of patients with chronic HFrEF (left ventricular ejection fraction <= 40%). Methods: The Adherence to guideline-directed medical and device Therapy in outpAtients with HFrEF (ATA) study is a prospective, multicenter, observational study conducted in 24 centers from January 2019 to June 2019. Results: The study included 1462 outpatients (male: 70.1%, mean age: 67 +/- 11 years, mean LVEF: 30%+/- 6%) with chronic HFrEF. Renin-angiotensin system (RAS) inhibitors, beta-blockers, mineralocorticoid receptor antagonists (MRAs), and ivabradin were used in 78.2%, 90.2%, 55.4%, and 12.1% of patients, respectively. The proportion of patients receiving target doses of medical treatments was 24.6% for RAS inhibitors, 9.9% for beta-blockers, and 10.5% for MRAs. Among patients who met the criteria for implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy (CRT), only 16.9% of patients received an ICD (167 of 983) and 34% (95 of 279) of patients underwent CRT (95 of 279). Conclusion: The ATA study shows that most HFrEF outpatients receive RAS inhibitors and beta-blockers but not MRAs or ivabradin when the medical reasons for nonuse, such as drug intolerance or contraindications, are taken into account. In addition, most eligible patients with HFrEF do not receive target doses of pharmacological treatments or guideline-recommended device therapy.Item Adjuvant Radiofrequency Thermocoagulation Improves the Outcome of Liquid Sclerotherapy in the Treatment of Spider Veins of the Leg: A Pilot Study(2021) Diken, Adem Ilkay; Alemdaroglu, Utku; Ozyalcin, Sertan; Hafez, Izzet; Tunel, Huseyin A.; Yalcinkaya, Adnan; Ecevit, , Ata N.; 0000-0002-8782-7603; 0000-0003-1175-1961; 33813962; ABE-8722-2020; AAD-5531-2021Objective This study evaluated the effect of low-energy radiofrequency thermocoagulation added to standard liquid sclerotherapy on clinical outcomes of patients with venous insufficiency. Patients and method We included 111 patients with spider veins CEAP/C1 stage. The patients were randomized into sclerotherapy (Group 1) and sclerotherapy + sclerotherapy immediately followed by low energy percutaneous RF thermocoagulation (Group 2) groups and followed up with same protocols prospectively. Results The study groups did not differ in terms of the mean age, body mass index, the number of spider veins and pre-interventional venous clinical severity scores (VCSS). Patients' self-assessed satisfaction ratings of cosmetic outcomes were found to be higher compared to the baseline (p = 0.001). While both techniques caused a significant decline in VCSS at postprocedural third month, it was observed that the type of applied intervention did not affect the VCSS (p = 0.43 and p = 0.93, respectively). There was a significant difference in hyperpigmentation and trapped blood between the two groups after the procedure (p = 0.009 and p = 0.02, respectively), there was no statistically significant difference in terms of skin necrosis (p = 0.52). A significant difference in the self-assessed cosmetic outcomes was observed in patients treated with sclerotherapy followed by low energy percutaneous RF thermocoagulation compared with patients whom sclerotherapy performed alone (p = 0.001). Discussion This study suggests that radiofrequency thermocoagulation added to the sclerotherapy provides better cosmetic outcomes with less treatment sessions and no additional complication rates.Item Adjuvant Small Pelvic Radiotherapy in Patients with Cervical Cancer Having Intermediate Risk Factors Only - Is It Sufficient?(2017) Onal, Huseyin Cem; Sari, Sezin Yuce; Guler, Ozan C.; Gultekin, Melis; Yildiz, Ferah; 0000-0002-2742-9021; 28848218; D-5195-2014Background: We sought to determine the outcomes of adjuvant small pelvic external beam radiotherapy (EBRT) and prognostic factors for survival and disease control. Patients and Methods: We retrospectively evaluated 113 cervical cancer patients treated with postoperative median 50.4-Gy small pelvic EBRT. We treated the surgical bed, bilateral parametria, paravaginal soft tissues, upper third of the vagina, and presacral lymphatics. Results: Median follow-up of all patients and survivors was 58 and 67 months, respectively. The 2-and 5-year overall survival (OS) and disease-free survival rates were 91 and 82%, and 85 and 74%, respectively. The locoregional failure rate was 10%. Age was a significant predictor for OS and distant metastasis-free survival (DMFS) on univariate analysis. The number of dissected lymph nodes being < 30 negatively affected the pelvic recurrence-free survival. The only independent predictor on multivariate analysis was older age for DMFS. Although no severe acute toxicity was observed, late grade >= 3 toxicity developed in 8 patients. Conclusion: Small pelvic EBRT produces satisfactory survival and locoregional control with acceptable toxicity, and can be an alternative to whole pelvic EBRT in selected cervical cancer patients. (C) 2017 S. Karger GmbH, FreiburgItem Administration of paracetamol versus dipyrone by intravenous patient-controlled analgesia for postoperative pain relief in children after tonsillectomy(2015) Sener, Mesut; Kocum, Aysu; Caliskan, Ebru; Yilmaz, Ismail; Caylakli, Fatma; Aribogan, Anis; 25443442Background and objective: We compared the efficacy of intravenous (iv) paracetamol versus dipyrone via patient-controlled analgesia (PCA) for postoperative pain relief in children. Methods: The study was composed of 120 children who had undergone elective tonsillectomy after receiving general anesthesia. Patients were divided into 3 groups according to the dosage of postoperative intravenous-patient-controlled analgesia: paracetamol, dipyrone, or placebo. Pain was evaluated using a 0- to 100-mm visual analog scale and 1- to 4-pain relief score at 30 min, 1, 2, 4, 6, 12, and 24h postoperatively. Pethidine (0.25 mg kg 1) was administered intravenously to patients requiring rescue analgesia. Pethidine requirements were recorded during the first 24h postoperatively, and treatment related adverse effects were noted. Results: Postoperative visual analog scale scores were significantly lower with paracetamol group compared with placebo group at 6h (p < 0.05), dipyrone group compared with placebo group at 30 min and 6 h (p <0.05). No significant differences regarding visual analog scale values at 1, 2, 4, 12, and 24h were found. No significant differences were found between groups with respect to pain relief score (p >0.05). Postoperative pethidine requirements were significantly lower with paracetamol and dipyrone groups compared with placebo group (62.5%, 68.4% vs 90%, p < 0.05). No significant differences were found between groups with respect to nausea, vomiting and the any other adverse effects of the drugs (p >0.05). Conclusions: Paracetamol and dipyrone have well tolerability profile and effective analgesic properties when administered iv-PCA for postoperative analgesia in children after tonsillectomy.

Fibrinolytic administration is still a life-saving choice in ST-segment elevated myocardial infarction (STEMI), but the rate of successful reperfusion can be inconsistent. Failed reperfusion adds additional clinical risks to rescue percutaneous coronary intervention for STEMI patients. The interval between the peak of the T wave and the end of the T wave (Tpe) and the ratio of Tpe and a corrected measurement of the time from the start of the Q wave to the end of the T wave (Tpe/QTc ratio) are relatively new electrocardiogram (ECG) indices and have not yet been tested in STEMI patients treated with fibrinolytic agents. Methods: A total of 177 STEMI patients (mean age: 60.5 +/- 11.1 years; 138 men and 39 women) were enrolled in this retrospective study to evaluate ECG parameters. The Tpe interval and the Tpe/QTc ratio at baseline and at the 90th minute following the administration of fibrinolytic therapy were analyzed. The clinical and ECG findings of successful and failed reperfusion groups were compared. Results: Successful reperfusion was achieved in 119 patients (67.2%). The average Tpe interval on the admission ECG was shorter (91.7 vs. 100.9 milliseconds [ms]) (p<0.001) and shortened more in the successful reperfusion group (9.3 vs. 4.5 ms) (p<0.001). A cut-off value of 89.0 ms for the Tpe interval on the admission ECG was found to be related to reperfusion success with a sensitivity of 90.9%. Conclusion: The Tpe interval was a predictor for reperfusion success in STEMI patients treated with fibrinolytic agents.Item Adrenal Myelolipoma: A Case Presentation(2018) Kervancioglu, Enis; Hasirci, Eray; Dirim, Ayhan; Aygun, Yuksel Cem; 0000-0002-6232-4313; 0000-0002-4147-2966; 0000-0003-3465-9092; AAM-3015-2021; AAI-7997-2021; AAM-4475-2021Adrenal myelolipomas are non-functional benign tumors of hematopoietic and mature adipose tissue. Adrenal myelolipomas, which are generally detected in post-mortem examinations, have become more detectable thanks to evolution and frequent use of imaging techniques. This presentation elaborates on a case of 35-year old male patient presenting with no complaint but diagnosed with adrenal myelolipoma in histopathological examination following surrenalectomy operation for an adrenal mass incidentally detected on ultrasonography and computed tomography work-up.Item Adrenergic receptor behaviors of mesenchymal stem cells obtained from different tissue sources and the effect of the receptor blockade on differentiation(2021) Maytalman, Erkan; Alizadeh Yegani, Arash; Kozanoglu, Ilknur; Aksu, Fazilet; 0000-0002-5268-1210; 34323168; AAE-1241-2021In this study, it was aimed to analyze behavioral changes of adrenergic receptors (ARs) in first three passages and osteogenic/adipogenic differentiation of mesenchymal stem cells (MSCs) derived from placenta fetal membrane (FM) and bone marrow (BM). It was also aimed to evaluate effects of receptor blockade on differentiation. We obtained first three passages of MSCs from placenta and BM samples. For cell identification, the cells were analyzed by flow cytometry using CD34, CD45 and CD3, CD105 antibodies in each passage. The effects of propranolol and phenoxybenzamine at incremental doses were analyzed by MTT. In addition, cell cultures were separately maintained with the blockers or without after second passage. After each passage and differentiation, alpha 1A, alpha 1B, alpha 2A, alpha 2B, beta 1, beta 2, beta 3 AR-mRNA expressions analyzed by RT-qPCR technique. BMP6 and PPARG mRNA expressions only after differentiation and passage 3 were analyzed. A microscopic examination was also performed. Our results showed that AR expression behaviors were different in MSCs obtained from different tissue sources. In particular, alpha(1A)-AR and alpha(2A)-AR were expressed with considerably high coefficients in differentiation under blocker effect in BM-derived MSCs. No such coefficients were observed in any group of placental MSCs. In addition, it was found that the blockers stimulated adipogenesis in BM-derived MSCs during osteogenic differentiation. MSCs exhibit protein expressions that vary according to source of tissue and differentiation. Given that MSCs from different sources are used for repair and modulation, our study makes implications of this variable expression intriguing in the clinical practice.Item Adult Still's disease: An unusual case with atypical skin and histopathological findings(2020) Vural, Ayse Tuncer; Ozcan, Deren; Tepeoglu, Merih; 0000-0002-9894-8005; AAK-5222-2021Adult Still's disease is a rare, acute systemic inflammatory disease characterized by a sudden rising fever, arthralgia/arthritis, neutrophilic leukocytosis and a typical salmon-colored macular or maculopapular rash associated elevated fever. Recently, atypical skin lesions with broad spectrum clinical features and distinctive histopathological findings have been reported in a rare case with active disease. Herein, we report an unusual case of Adult Still disease was presented and the characteristic features of atypical disease were highlighted.Item An advanced human error assessment approach: HEART and AV-DEMATEL(2019) Can, Guelin F.; Delice, Elif K.Human error assessment and reduction technique (HEART) is one of the most commonly used human error assessment approaches which computes human error probability (HEP) to prioritize errors related to human actions. HEART is a powerful tool considering error producing conditions (EPCs) which increase the HEP for generalized task versions named as generic task types (GTTs). HEART can give a solution including prevention of human-related errors (HREs) and reduction of the HREs' impacts via implementing additional controls. However, it has many shortcomings for real-life error assessments. In this context, this study aims to improve effective usage of HEART through an advanced version of decision-making trial and evaluation laboratory (AV-DEMATEL). The reason to perform AV-DEMATEL is to show the complex effect relations between main tasks (MTs), subtasks (STs), and EPCs in a process. For this aim, an integrated effect relation matrix is proposed for DEMATEL and importance weights of MTs, STs, and EPCs are computed based on this matrix. In addition, not only HREs are considered but also machine-related errors (MREs) are taken into account to make error assessment for the process. The proposed approach also provides flexibility to categorize STs in different GTTs. Finally, a new term "process error probability" including HREs' probabilities and MREs' probabilities is recommended to compute error probability in an integrated manner for the process. To utilize the proposed approach, an example of a steam boiler daily control process is given.Item The adverse effects of valproic acid on visual functions in the treatment of retinitis pigmentosa(2017) Yuce, Aslihan; Totan, Yuksel; Guler, Emre; Dervisogullari, Mehmet Serdar; 29044065Purpose: To evaluate the efficacy and safety of valproic acid (VPA) treatment in patients with retinitis pigmentosa (RP). Methods: A total of 48 eyes of 24 patients (13 males, 11 females) with RP prescribed VPA were included. The length of VPA treatment was 6-12 months (mean 9.4 months). Parameters evaluated were best-corrected visual acuity (BCVA) (logarithm of the minimum angle of resolution [logMAR]), visual field analyses (VFAs) with Humprey automated perimetry, multifocal electroretinography (ERG) with Roland-RETI scan, and VPA side effects. Results: Mean age was 34.3 +/- 10.3 years (range 18-56 years). Fifteen of the patients (30 eyes) had two ERG and VFA tracings, allowing comparison between baseline and follow-up (range 6-12 months). Mean BCVA before and after VPA therapy was 0.36 +/- 0.38 and 0.36 +/- 0.37 logMAR, respectively (P = 0.32). Quantitative perimetric indices including mean deviation and pattern standard deviation were not significantly changed after VPA therapy (P > 0.05). P1 amplitudes (in terms of nV/deg(2) and mV) of ERG waves were significantly decreased in the rings 1, 3, and 4 after VPA therapy (P < 0.05). Regarding the N1 amplitudes, the only significant decrease was observed in area 1 (P = 0.03). In addition, N1 latency was significantly increased in area 3 after VPA therapy (P = 0.04). Conclusions: VPA therapy did not have any significant benefit on BCVA and VFA. In addition, it may be associated with decline in some ERG parameters. Therefore, physicians should avoid prescribing VPA for RP until its safety and efficacy are appropriately evaluated.Item After a Workshop on the Novel Antivirals for Treatment of Hepatitis C Virus Infection (4-6 December 2015, Istanbul)(2016) Tekin, Suda; Aygen, Bilgehan; Aydin, Mehtap; Simsek, FundaItem Age estimation in Turkish children and young adolescents using fourth cervical vertebra(2020) Gulsahi, Ayse; Cehreli, Sevi Burcak; Galic, Ivan; Ferrante, Luigi; Cameriere, Roberto; 31915966This study aimed to test radiographic projections of the posterior and anterior sides of the C4 vertebral body for age estimation in a cross-sectional sample of Turkish children and adolescents from the Baskent University Faculty of Dentistry. A sample of 232 x-rays from individuals aged between 5 and 15 years (101 boys and 131 girls) was analysed to investigate the correlation of age and changes in the projection ratio of the anterior and posterior sides of the body of the fourth cervical vertebra (Vba) in lateral cephalograms. The Normal Bayesian Calibration (NBC) model for age estimation was used to assess the relationship between Vba and age. The intra-observer repeatability and inter-observer agreement were 0.95 and 0.94, respectively. Age distribution gradually increased as Vba increased up to 14 years in both sexes. The difference between chronological and estimated ages did not increase with the increase in age. Calibration distributions of the dataset by the evaluation of Vba suggested mean absolute errors (MAEs) of 0.879 years and 0.906 years (mean interquartile ranges (MIQRs) 1.290 and 1.435 years)) in boys and girls, respectively. The biases of the estimates (beta(ERR)) were 0.013 and 0.027 for boys and girls, respectively. In conclusion, the NBC method on Vba variable appears to be suitable for age estimation in Turkish children and adolescents.Item Age- and Gender-Related Variability in Nasal Tip Support(2020) Koycu, Alper; Erol, Ozan; Buyuklu, Fuat Adnan; Jafarov, Sabuhi; Berker, Sinem; 0000-0003-1528-0036; 0000-0003-1290-3509; 0000-0002-7302-4199; 31834522; W-5941-2018; AAF-3650-2021; AAI-8044-2021Background The age at which nasal tip support changes start to occur is unknown. Evaluation of nasal tip support is difficult, especially as the ideal nasal tip support pressure remains elusive. The aim of this study is to determine the nasal tip support pressure alterations relative to age and sex. Objectives The aim of this study is to determine the changers in resistance of the nasal tip support in relation to age and sex. Methods This prospective clinical study was conducted between January and April 2019 at a tertiary health facility. Nasal tip resistances were measured in four different age-groups (20-29, 30-39, 40-64, and > 65 years) with a digital Newton meter. A total of 159 patients with a minimum of 36 patients per group were included in the study. Nasal tip resistance measurements were compared among nasal tip displacement distances of 2, 3, and 4 mm, focusing on age and sex. Results The nasal tip resistance of the 20-29 age-group was significantly higher at 2, 3, and 4 mm nasal tip displacement distances, when compared with the 30-39 and 40-64 age-groups, whereas compared to the > 65 years group, it was significantly higher at 3 and 4 mm nasal tip displacement distances (p < 0.005). Nasal tip resistance of males was found to be significantly higher than that of females, at 3 and 4 mm nasal tip displacement distances (p < 0.001). Conclusions Nasal tip resistance is higher in males and universally decreases significantly after 30 years of age while remaining constant at later ages. Therefore, surgeons should prefer nasal tip resistance increasing techniques in the rhinoplasty operations that are performed on patients even from early years of age, in order to maintain and strengthen the nasal tip resistance.
