We present the case of an unusual presentation of Dressler’s syndrome and the important role of new imaging techniques in its diagnosis. A 42-year-old man was admitted with progressive dyspnoea and pleuritic chest pain during the last two months. Physical examination showed signs of hemodynamic instability (BP 75/40, HR 120 bpm). X-Ray showed cardiomegaly and electrocardiogram was suggestive of chronic anterior myocardial infarction. Transthoracic echocardiography showed pericardial effusion with signs of hemodynamic compromise. Emergent cardiac surgery was performed with suspicion of cardiac rupture. Only fibrinous material and serous fluid was found. 72 hours later he required reoperation because of recurrence of cardiac tamponade. Pleuropericardial window was made. Anti-inflammatory treatment was initiated. At discharge a magnetic resonance imaging study was performed. Diffuse pericardial inflammation consistent with a diagnosis of Dressler’s syndrome (DS) was demonstrated in T2- weighted black-blood and late enhancement sequences. One month later neither pleural nor pericardial effusion had recurred. Postinfarction pericardial effusions are common and magnetic resonance imaging has proven useful in determining its aetiology.

We present the case of an unusual complication after percutaneous closure of a giant coronary artery fis-tula. A 76-year-old man with previous admissions due to right heart failure and previous history of atrial fibrillation under acenocumarol, was admitted to our hospital for new onset of symptoms, characterized by progressive dyspnoea and peripheral edema. Physical examination revealed signs of congestive heart failure and a continuous murmur loudest along the lower sternal border. X-Ray showed cardiomegaly due to right chambers dilatation. Transthoracic echocardiography showed right chambers pressure and volume overload, with right ventricular enlargement and dysfunction, tricuspid annulus dilatation and severe tricuspid regurgitation. Cardiac catheterization showed significant elevation of right atrial pressure, as well as significant step-up of oxygen saturation in this chamber. Coronary angiography revealed the presence of a large fistula between the circumflex coronary artery (CCA) and coronary sinus (CS), with severe dilation of the CCA (maximum diameter20 mm). An Amplatzer? PDA was implanted in a distal elbow of the fistula with initailly good results. Anticoagulant therapy was then reinitiated, and a few days later, the patient developed clinical worsening of heart failure and dyspnoea. Echocardiogram showed significant pericardial effusion. Pleuropericardial window was then made draining a500 cm3 of bloody pericardial effusion. The postoperative outcome was excellent, with symptomatic relief and no signs of heart failure.

In this paper we construct developable surface patches which are bounded by two rational or NURBS curves,though the resulting patch is not a rational or NURBS surface in general.This is accomplished by reparameterizing one of the boundary curves.The reparameterization function is the solution of an algebraic equation.For the relevant case of cubic or cubic spline curves,this equation is quartic at most,quadratic if the curves are B´ezier or splines and lie on parallel planes,and hence it may be solved either by standard analytical or numerical methods.

We consider nested or multiscale models to study the effect of the temporal evolution of the disease within the host in the population dynamics of the disease,for one and two infectious agents.We assumed a coupling between the within-host infection rate and the between-host transmission rate.The age of infection within each individual in a population affects the probability of transmission of the disease to a susceptible host and this will affect the temporal evolution of the disease in the host population.To analyze the infection within the host,we consider bacterial-like and viral-like infections.In the model for two infectious agents,we found that,when strain 2 has a basic reproduction number R02 greater than the basic reproduction number R01 of strain 1,strain 2 replaces strain 1 in the population.However,if R02>R01 but the values are closer,the replacement does not occur immediately and both strains can coexist for a long time.We applied the model to a scenario in which patients infected with the hepatitis C virus(HCV)are cleared of HCV when super-infected with the hepatitis A virus(HAV).We compared the time for the replacement of HCV by HAV in the population considering instantaneous and noninstantaneous replacement within the individuals.The model developed can be generalized for more than two infectious agents.

Arthroscopic hip surgery has become an established diagnostic and therapeutic method for addressing different hip pathologies. This paper focuses on hip arthroscopy for treating hip disorders in children under the age of 10. Arthroscopic hip surgery was performed 30 times on 24 children to address various hip pathologies. Indications were septic arthritis, benign soft tissue tumors, traumatic and congenital hip dislocation, juvenile idiopathic arthritis and osteochondroma of the acetabulum. Diagnostic arthroscopy was technically feasible in all cases. All cases of septic arthritis were successful treated using arthroscopic lavage and antibiotics. In the miscellaneous cases (benign fibrous tumor, juvenile idiopathic arthritis, osteochondroma congenital hip dislocations and traumatic hip dislocation) 4 hips had additional open surgery including surgical dislocation with synovectomy, open reduction and stabilization of the fractured posterior rim of the acetabulum, acetabulopasty and open resection of an osteochondroma with acetabuloplasty. In conclusion arthroscopic hip surgery is an additional diagnostic and therapeutic method that is suitable for treating different hip pathologies in children under the age of 10. Primary treatment of septic arthritis can be done easy by hip arthroscopy. Using cannulated mini arthroscopic hip instruments (2.7 mm), the range of application can be expanded to include treatment of very young infants. Hip arthroscopy can reduce the need of open surgery but cannot replace bony procedures in hip surgery.

Let （Ω, ∑） be a measurable space and mo ： E→ Xo and m1 ： E → X1 be positive vector measures with values in the Banach KSthe function spaces Xo and X1. If 0 〈 a 〈 1, we define a X01-ax1a new vector measure [m0, m]a with values in the Calderdn lattice interpolation space and we analyze the space of integrable functions with respect to measure [m0, m1]a in order to prove suitable extensions of the classical Stein Weiss formulas that hold for the complex interpolation of LP-spaces. Since each p-convex order continuous Kothe function space with weak order unit can be represented as a space of p-integrable functions with respect to a vector measure, we provide in this way a technique to obtain representations of the corresponding complex interpolation spaces. As applications, we provide a Riesz-Thorin theorem for spaces of p-integrable functions with respect to vector measures and a formula for representing the interpolation of the injective tensor product of such spaces.

This paper seeks to determine how the overlap of several infrared beams affects the tracked position of the user, depending on the angle of incidence of light, distance to the target, distance between sensors, and the number of capture devices used. We also try to show that under ideal conditions using several Kinect sensors increases the precision of the data collected. The results obtained can be used in the design of telerehabilitation environments in which several RGB-D cameras are needed to improve precision or increase the tracking range. A numerical analysis of the results is included and comparisons are made with the results of other studies. Finally, we describe a system that implements intelligent methods for the rehabilitation of patients based on the results of the tests carried out.

In this paper we present a model to estimate the density of aedes mosquitoes in a community affected by dengue.The method consists in fitting a continuous function to the incidence of dengue infections,from which the density of infected mosquitoes is derived straightforwardly.Further derivations allow the calculation of the latent and susceptible mosquitoes'densities,the sum of the three equals the total mosquitoes'density.The method is illustrated with the case of the risk of urban yellow fever resurgence in dengue infested areas but the same procedures apply for other aedes-transmitted infections like Zika and chikungunya viruses.
