Discussion Cardiac hydatid cysts are extremely rare particularly in the pediatric age. Because of its potential risk for rupture resulting in systemic or pulmonary dissemination, embolism or anaphylactic shock, prompt diagnosis and early surgery is crucial.

According to our knowledge, this is the first case of acute right ventricle myocarditis and right heart failure do to acute cholecyctitis.

This paper presents a higher order, three-dimensional boundary element method for investigating the dynamics and stability of elastic structures containing and/or submerged in flowing fluid. The method developed can be applied to any shape of elastic structures partially or completely in contact with fluid. In the mathematical model, it is assumed that the fluid is ideal (i.e. inviscid, incompressible and its motion is irrotational). The fluid—structure interaction forces are calculated using the higher order boundary element method, and the finite element method is employed for the structural analysis. In this study, it is assumed that the elastic structure vibrates in its in vacuo modes when it is in contact with flowing fluid, and that each mode gives rise to a corresponding surface pressure distribution on the wetted surface of the structure. The in vacuo dynamic properties of the dry elastic structure are obtained by using standard finite element software. In the wet part of the analysis, the wetted surface of the elastic structure is idealized by using appropriate boundary elements, referred to as hydrodynamic panels. Over each hydrodynamic panel, higher order distributions (linear and quadratic) are adopted in the present study in order to obtain a better convergence, in contrast to Ugurlu and Ergin (2006) assuming constant distribution over each hydrodynamic panel. The fluid—structure interaction forces are calculated in terms of the generalized added mass coefficients, generalized Coriolis fluid force coefficients, and generalized centrifugal fluid force coefficients. To assess the influence of flowing fluid and end support conditions (e.g. simply supported ends, clamped ends, and cantilever cylindrical shell) on the dynamic response behaviour and stability of the cylindrical shells, the non-dimensional wet frequencies and associated vibration modes are presented as a function of the non-dimensional axial flow velocity, and the calculations compare well with the analytical solutions found in the open literature.

This prospective, randomized, double-blind study was designed to compare the recovery characteristics of remifentanil and fentanyl in combination with propofol for direct current cardioversion. Patients undergoing elective cardioversion received either intravenous fentanyl 1 μg/kg (n=33) or remifentanil 0.25 μg/kg (n=30) and propofol was titrated to a Ramsay sedation score of 5 by slow intravenous injection. Heart rate, systolic, diastolic and mean blood pressures decreased significantly following sedation in both groups but did not show a significant difference between the groups. Time to answer a question (306±83 vs 383±131s, mean±SD, P=0.014) and time to sit up (412±90 vs 511±126s, P=0.002) were significantly shorter in the remifentanil group compared to the fentanyl group. Side-effects and patient discomfort were similar for both groups. Remifentanil can be used as a suitable supplement to propofol for direct current cardioversion and may provide a faster recovery profile than fentanyl.

Methods 45 consecutive acute ST- elevation myocardial infarction patients were performed primary angioplasty between January and May 2012 at our hospital.

Objectives To investigate the safety and efficacy of primary percutaneous transluminal coronary angioplasty (PPTCA) in patients with acute myocardial infarction (AMI) at a off- site cardiac surgery hospital.

Thrombolytic therapy is still not used widely for treatment of deep vein thrombosis despite its known efficacy. This reluctance to use it stems from worries about its hemorrhagic complications. In a 4-year period 97 patients with deep vein thrombosis diagnosed by duplex study were enrolled into the study. Fifty patients received streptokinase as a bolus of 250,000 units followed by 100,000 units/hr with a maximum of 4,000,000 units and 47 patients received anticoagulation with heparin. Minor hemorrhagic complications occurred in 2 patients (4%) in the thrombolytic therapy group. An improvement in the control duplex study was observed in 56% of the patients in the thrombolytic therapy group compared to 5% in the heparin group (p=0.000). The patients treated within 4 days of onset of symptoms had significantly higher success rates compared to those treated later (p=0.000). Higher success rates were obtained for those with either femoral vein or more distal venous thrombosis compared to those with iliac vein and vena cava thrombosis (p=0.007). These results show that systemic low dose streptokinase achieves significantly higher recanalization rates compared to heparin alone. Hemorrhagic complications at these dose levels are within acceptable ranges. Low dose streptokinase regimen could be beneficial in patients who present within 4 days of femoral or more distal venous thrombosis.

In April and May 1996, two cases of PDA ligation were performed firstly in Turkey by the method of video assisted thoracoscopic surgery (VATS) in Dokuz Eylül Medical Faculty, Thoracic and Cardiovascular Surgery Department. There was not any complication in these patients in the postoperative period and they were discharged on the second day in symptom-free condition by the detection of closed ductus in their echocardiographic examination. Between February 1993 and October 1996, a total of 46 patients have undergone interventional application by VATS. While in six of these patients the procedure could not be manipulated because of massive pleural fibrosis, there was no mortality or morbidity among the patients, and they were discharged on average on the second day. The ratio of complications, such as bleeding, air leak, arrhythmia and empyema are so low in these operations, and hospital stay, with return to work time are shorter than with the open technique.

Retaining a dissipation-free state while carrying large electrical currents is a challenge that needs to be solved to enable commercial applications of high-temperature superconductivity. Here, we show that the controlled combination of two effective pinning centres (randomly distributed nanoparticles and self-assembled columnar defects) is possible and effective. By simply changing the temperature or growth rate during pulsed-laser deposition of BaZrO 3 -doped YBa 2 Cu 3 O 7 films, we can vary the ratio of these defects, tuning the field and angular critical-current ( I c ) performance to maximize I c . We show that the defects’ microstructure is governed by the growth kinetics and that the best results are obtained with a mixture of splayed columnar defects and random nanoparticles. The very high I c arises from a complex vortex pinning landscape where columnar defects provide large pinning energy, while splay and nanoparticles inhibit flux creep. This knowledge is used to produce thick films with remarkable I c ( H ) and nearly isotropic angle dependence. Applications of high-temperature superconductivity rely on transporting a large current without dissipation. It is now shown how the inclusion of a combination of two types of defect can be used to control and optimize the performance of the high-temperature superconductor YBa 2 Cu 3 O 7 .
