There are a number of variations on the standard singleor double-cuff Tenckhoff catheter that are now available which have been developed in an attempt to improve both the infectious complications, such as peritonitis and ESIs, and mechanical complications, such as flow problems and tip malposition. These variants include a coiled-tip Tenckhoff, Toronto Western Hospital catheter with silicone d...

A survey of recreational boat-based and shore-based fishing in the Swan-Canning Estuary Basin was conducted between August 1998 and July 1999. During the survey 1,302 interviews were conducted at boat ramps. The majority of these (62%) were not involved in fishing or crabbing activities, with a further 18 per cent fishing in the adjacent ocean. Of the remainder, 139 boats had been crabbing and ...

The Swan-Ganz balloon flotation catheter was introduced in 1970. It can be placed at the bedside within a few minutes even in critically ill patients. Although placement of these catheters is not difficult, some training and experience are required to avoid complications and for proper interpretation of the hemodynamic data that can be obtained by pulmonary artery catheterization. Because of th...

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 ...
