Complications derived from pulmonary artery catheter placement are about 3%-17%,1 from the most frequent and mild (carotid puncture, extrasystoles, etc) to the most severe (pulmonary artery rupture, pulmonary infarction, ventricular fibrillation, atrioventricular block, etc), and rare ones, such as intravascular catheter knotting, located preferentially in the right atrium (RA) or right ventric...

Background—Although several studies have demonstrated a good correlation between Doppler echocardiographic and invasive measurements of single hemodynamic variables, the accuracy of echocardiography in providing a comprehensive assessment in individual patients has not been validated. The aim of this study was to assess the accuracy and clinical applicability of Doppler echocardiography in dete...

This is how we successfully treat chronic boutonnieres 1) serial cast them until full or near full extension of the PIP joint is obtained and the DIP joint is able to flex as much as the DIP joint of the same finger on the other hand. The lateral bands are still volar to the axis of the PIP joint if the DIP is still hyperextending. 2) start an 8 week full time (24/7) PIP extension splint. In th...

The class of symmetric functions is based on the OneMax function by a subsequent assigning application of a real valued function. In this work we derive a sharp boundary between those problem instances that are solvable in polynomial time by the Metropolis algorithm and those that need at least exponential time. This result is both proven theoretically and illustrated by experimental data. The ...

Free and weakly interacting particles are described by a secondquantized nonlinear Schrödinger equation, or relativistic versions of it. They describe Gaussian random walks with collisions. By contrast, the fields of strongly interacting particles are governed by effective actions, whose extremum yields fractional field equations. Their particle orbits perform universal Lévy walks with heavy ta...
