Abstract: Introduction: For tracheal stenosis, tracheal resection and anastomosis is widely considered the treatment of choice. However, this surgical approach is not feasible when the glottis and subglottis are involved or in patients with a poor general condition and tracheal stents are a plausible means of providing a permanent or temporary airway opening. Objectives: Evaluate the features and the results of patients with Montgomery T-tube in tracheal stenosis. Methods: Fifteen patients with Myer-Cotton grades 2-3 circular cicatricial tracheal stenosis who received a Montgomery T-tube between 2002-2011 were analyzed in terms of age, gender, etiology, duration of intubation, location and size of the stenotic segment on computed tomography(CT), follow-up time with the T-tube, the complications that occurred after T-tube removed and additional tracheal surgery. Conclusion: A T-tube can be applied in tracheal stenosis at the first treatment before attempting surgery. The patients should be closely followed-up due to the possibility of re-stenosis and other complications.

The E-government Readiness Index is a composite index created from the Neural Index, the Telecommunication Infrastructure Index and the Human Resources Index. Calculated annually by the World Bank, this index offers information on such issues as the provision of public services and the use of these services by individuals and institutions. In this study, we examine whether the E-government Readiness Index provides information on the compliance of the business lives of countries with an e-government structure by using neural networks.

Turkish Journal of Urology , 2011,
Abstract: Objective: Due to some disadvantages of prone position, which is the most preferred approach in percutaneous nephrolithotomy (PCNL), supine PCNL has been described. In this study, we aimed to present the outcome of PCNL applied in supine position in our clinic.Materials and methods: Between April 2010 and January 2011, 29 supine PCNL operations were performed on 29 renal units in our clinic. All the patients had primary renal stones without history of open or percutaneous surgery. The patients were evaluated by intravenous pyelography or computed tomography. At the begining of the procedure, renal pillows were located under the ipsilateral side, and ureteral catheters were placed in lithotomy position. Posterior axillary line was marked and never passed through anterior of this line during the renal access. Ultrasonographic access was done in first 6 cases, and then scopic access was performed to other 23 cases. Amplatz dilatators were used on 9 patients and balloon dilatators on 20 patients. The stones were broken with ultrasonographic and pneumautic lithotripsy by using 26F nephroscope, and then fragments were taken out. Results: Residual stones (≥4 mm) were detected in 5 patients, and 24 procedures were ended as stone-free (82%). Only one access was performed in all patients. In 5 patients who were without bleeding and extravasation, and who were stone-free (17%); the procedure was completed as tubeless by placing retrograde 6F double-J catheter. Mean hospitalization time was 3.1 days (range 1-5 days). Mean operating time was 64 min (range 25-130 min). Postoperative fever was developed in 3 patients. Double-J catheter was placed in a patient at postoperative 5th day because of prolonged urine leakage. No other surgical and anesthetic complication was detected.Conclusion: Supine approach of the PCNL can be preferred in terms of patient comfort, allowing retrograde manipulations, and acceptable anesthetic risks. This position has similar success and complication rates with prone PCNL.

Abstract: Objective: Candida species are often isolated from respiratory specimens of patients with a history of long duration of hospitalization, immunosuppression, diabetes, alcoholism, history of wide spectrum antibiotic or corticosteroid usage. The aim of this retrospective study is to investigate the effect of isolation of Candida species from respiratory specimens on prognosis.Material and Method: Patients in the Department of Chest Disease in whom Candida species had been grown in ≥2 respiratory specimens obtained at the same or at different time periods within the last two years were enrolled in the study. Demographic features of the patients, risk factors for fungal infection, and the effect of this infection on prognosis were evaluated.Results: Out of 47 cases (mean age 67.6±14.6 yrs, 33 males) enrolled in the study, 29 were diagnosed as pneumonia at admission. The most frequent species isolated was C. albicans (68.1%). Fifty bacterial agents were isolated from respiratory specimens of 29 patients (61.7%) initially or on follow-up along with Candida species. Immunosuppression was detected in 28 patients (59.6%). Mean duration of hospitalization was 22.3±15.2 days and 26 patients (55.3%) died. Radiologically, multiple-zone involvement, C. tropicalis isolation, high APACHE II score, co-existing bacterial infection, low PaO2/FiO2 ratio, and low albumin levels were found to be associated with mortality.Conclusion: This study showed that Candida species could also be isolated in respiratory specimens of non-immunosuppressed patients and mortality was high. It was concluded that bacterial co-infection and C. tropicalis isolation affected the prognosis negatively.

Abstract: Anxiety is a discomfort and a kind of fear feeling of which individuals do not know the reasons but feel against the events which they regard dangerous and threatening. The indicator of anxiety in behaviors is a switch from the state of excessive excitement and activeness to sluggishness. Fear, nervousness, excessive anger, disgust, tiredness, muscle aches and psychological complaints are the most common indicators of the anxiety. “State anxiety” is permanent emotional reactions which the individual shows to the permanent states of which the density changes according to the conditions. “The state anxiety” level is high in the conditions which the individual comprehends the stressing state as threatening and it is low in the conditions which the danger is not comprehended as threatening. “State Anxiety” affects the sportsman’s motivation, concentration, coordination, the ability to determine, self-confidence, kondisyonel and coordinative abilities, which may be determinative on his/her performance. “State Anxiety” , which is occurred before or during the events that are called dangerous, is generally based on logical reasons and can be understood by other people. Trait anxiety is the perceiving the situations causing stress as a dangerous or threatening and the increasing and gaining continuity of the frequency and the density of emotional reactions against these threats. Trait anxiety is common and continuous anxiety which does not depend on a certain event or situation.. As the aim in sports competitions is based on probability of winning and losing, desire to have a good performance to be able to win sometimes creates negative impacts, and increasing complex emotions bring about the bad performance. Sports psychologists have consensus that it is necessary for the athletes to have a certain anxiety level for high performance. Lower or higher level affects the performance negatively. High anxiety level for the athletes is generally attained as the athletes come close to the borders of performance capacity. In other words, while coming close to the borders of performance capacity, anxiety density is increasing. If the athletes’ emotions are on the level of enthusiasm, horror or anger, many mental functions particularly thinking and perceiving get weak, and it is not possible to carry out activities consciously. To reach psycho-physic balance condition that a sportsman has, it is necessary to abolish the emotions. On the other hand, it is a big mistake to go on keeping the player on the game and expect a result. The physiological reactions which are shown

Abstract: Chronic Spontaneous Urticaria (CSU) is a chronic disease with significant negative impact on quality of life of patients. The direct and indirect costs of the disease can be substantial both for the health care system and society. The aim of this research is to estimate the cost of mild, moderate and severe CSU in Turkey and to forecast the cost of the disease from the payer (Social Security Institution—SSI) perspective. Expert opinions with Delphi technique were used in order to determine the cost items and their frequency. A questionnaire was designed to outline resources used in the out-patient, inpatient and emergency care episodes and was answered by dermatologists followed by a consensus meeting. Unit costs were calculated from the price list of the SSI. The annual total cost of treating the disease to the SSI was estimated as 262,111,978TL (94,417,870€) comprising 0.06% of the total healthcare budget in 2013. Since there is limited information about the cost of CSU in Turkey, the methodology and results of this study are unique and very important.

Abstract: Background: The 12-lead surface electrocardiogram (ECG) is a useful tool to predict both atrial and ventricular arrhythmias via P-wave and QT measurements and its derivatives. Polycythemia vera (PV) is a chronic myeloproliferative disorder associated with cardiovascular events. The aim of this study was to assess ECG findings of patients with PV. Method and materials: Sixty patients with PV (34 male, mean age 58±11 years) and 60 age and gender-matched healthy volunteers were enrolled into the study. From the 12-lead surface ECG, P-wave and both conventional QT measurements and transmyocardial repolarization parameters (Tpeak-Tend interval (Tp-Te) and derivatives) were evaluated digitally by two experienced cardiologists. In addition, a novel parameter, Pi was calculated digitally as the standard deviation of the P-wave duration across the 12 ECG leads. Results: QT duration and corrected QT interval were significantly longer in the PV group compared to healthy controls (p<0.01 and p<0.01, respectively). The Tp-Te was longer and the Tp-Te/QT ratio was significantly higher in the PV group compared to the controls. P-wave analyses showed that all P-wave parameters including Pmax, Pmin, P dispersion, and Pi were significantly prolonged in PV patients compared to the controls. The increase of both Tp-Te and P max in the PV group was independent of age, BMI, diabetes and hypertension, gender, systolic blood pressure, hemoglobin, hematocrit, left atrial dimension, left ventricular end-diastolic diameter and early deceleration time in a univariate analysis of co-variance model (F=11.097, p=0.001 and F=31.537, p=0.0001, respectively). Conclusion: The present study demonstrated that PV may be associated with electrocardiographic abnormalities of both atrium and ventricle.

Abstract: Constrictive pericarditis is an uncommon cause of heart failure. It is a clinical entity caused by thickening, fibrosis, and/or calcification of the pericardium. We present a 50-year-old female patient who was admitted to our institution with a 6-month history of progressive dyspnea on exertion, abdominal swelling, and lower extremity edema. Her chest X-ray revealed an oblique linear calcification in the cardiac silhouette. Transthoracic echocardiography revealed biatrial enlargement. Left ventricular size and systolic function were normal. Cardiac computed tomography revealed the pericardial thickening (>5?mm) and heavy calcification in left atrioventricular groove. Simultaneous right and left heart catheterization showed elevation and equalization of right-sided and left-sided diastolic filling pressures, with characteristic dip, and plateau. Pericardiectomy was performed which revealed a thick, fibrous, calcified, and densely adherent pericardium constricting the heart. The postoperative period was uneventful and was in NYHA functional class I after 3 months. 1. Introduction Constrictive pericarditis (CP) is uncommon cause of heart failure. It is a clinical entity caused by thickening, fibrosis, and/or calcification of the pericardium. This entity often leads to impairment of diastolic filling, resulting predominantly in symptoms of right heart failure [1]. Currently, idiopathic or viral pericarditis is the predominant cause in the industrialized countries, followed by cardiac surgery and mediastinal irradiation, which are as well the major and increasing causes of CP in the industrialized countries [2–4]. Tuberculosis is still a common cause of CP in developing and underdeveloped countries, as well as in the immunosuppressed patients [5]. Modern series from Saudi Arabia, Mexico, Turkey, and India document tuberculosis in 38% to 83% of all cases of CP. Pericardial disease rarely presents as the initial manifestation of tuberculosis [6–9]. Although pericardial calcification on chest X-ray suggests constriction, it is not diagnostic but may lead to more detailed investigations. A pericardial thickness less than 2?mm is normal and greater than 6?mm in size is specific for constriction [10]. Cardiac CT and MRI can detect pericardial thickening and calcification with high accuracy [11]. Echocardiography and new Doppler techniques are very useful for differential diagnosis between CP and restrictive cardiomyopathy [12, 13]. The gold standard for diagnosis is cardiac catheterization with analysis of intracavitary pressure curves, which are high in end
