    Association between Body Mass Index, Lipid Profiles, and Types of Urinary Stones
    (Taylor & Francis Ltd, 2012) Inci, Mehmet; Demirtas, Abdullah; Sarli, Bahadir; Akinsal, Emrecan; Baydilli, Numan
    Objective: The purpose of this study was to determine the differences in body mass index (BMI), levels of cholesterol, and levels of triglycerides (TGs) among urolithiasis patients with different stone compositions. Materials and methods: Forty-nine patients who had a diagnosis of nephrolithiasis and had undergone open surgery or percutaneous surgery were included, and patients without urolithiasis were randomly selected as controls. Urinary stones were collected and analyzed using infrared spectroscopy. Data relating to patient's age, BMI at diagnosis, serum total cholesterol (TC), high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol (LDL-C) were collected. The stone groups including calcium oxalate monohydrate-calcium oxalate dihydrate (COM-COD), COM, and uric acid were compared with one another and with the control group. In addition, the stone formers group (COM-COD, COM, uric acid, calcium phosphate, and mixed-type stones) was compared to the control group. Results: BMI, TC, and TG levels were significantly higher in stone formers compared with the control group; this association of BMI and TC with stone formation was more prominent in uric acid and COM-COD stone formers, but there was no such prominence for COM stones. LDL-C levels in COM-COD stone formers were significantly higher when compared with COM stone formers. Conclusion: Elevated BMI, hypercholesterolemia, and hyperlipidemia, which are leading components of metabolic syndrome, may be associated with different types of urinary stone formation.

    The changes in preferences for venous thromboembolism prophylaxis after total joint arthroplasty in Turkey: A survey
    (Turkish Joint Diseases Foundation, 2018) Azboy, Nesrullah; Cimen, Cgouzhan; Demirtas, Abdullah; Elci, Serhat; Azboy, Ibrahim
    Objectives: This study aims to investigate the changes in preferences of orthopedic surgeons for venous thromboembolism (VTE) prophylaxis after total knee arthroplasty (TKA) and total hip arthroplasty (THA) and the factors that affect such changes in Turkey. Materials and methods: Turkish Orthopedics and Traumatology Association members (n=2.180) were invited to fill in the questionnaire. A total of 366 orthopedic surgeons responded and completed questionnaire. The questionnaire was comprised of 12 questions investigating the demographics of surgeons. their preferences for VTE prophylaxis. the changes in their preferences over the course of the past three years. and the causes of such changes. Results: In the past three years, 31.1% of surgeons changed their VTE prophylaxis method and 32.7% used risk classifications. The use of low molecular weight heparin (LMWH) decreased from 89.4% to 42.5% and from 85.8% to 44.2% after TKA and THA. respectively. The use of aspirin increased from 10.6% to 43.4% and from 9.7% to 37.2% after TKA and TIIA, respectively. The use of oral anticoagulants increased from 11.5% to 41.6% and from 10.6% to 39.8% after TKA and THA, respectively. Still, orthopedic surgeons in Turkey preferred LN1W11 at rates of 75.7% and 74% after TKA and Tim. respectively. Congressional presentations were the first (47.7%) among the causes of the changes in preferences for VTE prophylaxis. Preferences of up to 60% of surgeons working at universities were influenced by the American Academy of Orthopedic Surgeons guidelines. Conclusion: In the past three years, approximately one third of orthopedic surgeons changed their preferences for VTE prophylaxis after total joint arthroplasty in Turkey. Changes in preferences were largely in favor of aspirin and oral anticoagulants in parallel to changes in guidelines for VTE prevention.

    The Investigation of Relationship between Coronary Artery Ectasia, Benign Prostatic Enlargement, and Lower Urinary Tract Symptoms
    (Elsevier Science Inc, 2015) Inci, Mehmet; Baydilli, Numan; Akcay, Adnan Burak; Demirtas, Abdullah; Rifaioglu, Mehmet Murat; Gozukara, Kerem Han; Kaya, Mehmet Gungor
    OBJECTIVE To investigate benign prostatic enlargement (BPE) and lower urinary tract symptoms (LUTS) in patients with coronary artery ectasia (CAE). The relation between CAE, BPE, and LUTS has not been studied so far. METHODS We investigated BPE and LUTS symptoms in 47 men with CAE, 45 men with coronary artery disease (CAD), and 47 male controls with normal coronary arteries. LUTS was evaluated by the International Prostate Symptom Score (IPSS). BPE was evaluated with transabdominal ultrasonography. CAD was defined as myocardial infarction and angiographically diagnosed coronary disease. CAE was defined as being without any stenotic lesions with a visual assessment of the coronary arteries showing a luminal dilatation >= 1.5 fold of the adjacent normal coronary segments. RESULTS Prostate volume was higher in CAE and CAD patients compared with that of the control subjects, respectively (41.0 +/- 10.4 vs 33.5 +/- 9.4 cm(3); 39.1 +/- 10.3 vs 33.5 +/- 9.4 cm3; P = .0001); total IPSS was higher in CAD and CAE patients compared with that of the control subjects (P = .0001). Postmictional residual urine volume was higher in CAE and CAD patients compared with that of the control subjects (P = .002). CONCLUSION We showed that patients with CAE have higher prostate volume, IPSS, and postmictional residual urine volume compared with those of controls with normal coronary angiograms. This study proposes that BPE, LUTS, and CAE maybe different disorders to a common vascular pathology and endothelial dysfunction. This study showed that BPE and LUTS were frequently seen in CAE at least as much as in CAD. Therefore, LUTS and BPE should be kept in mind for CAE patients in follow-ups. (C) 2015 Elsevier Inc.
