OBJECTIVE To determine the clinical usefulness of skin temperature patterns for tracking reflex sympathetic dystrophy (RSD) by assessing (a) long-term relationships between changes in pain due to RSD and patterns of near surface blood flow and (b) relationships between site of pain and site of greatest asymmetries in near surface blood flow patterns. … (More)
OBJECTIVES We compared the efficacy of two different mapping techniques in identifying the ablation site for atrial tachycardia. Moreover, we evaluated the additive positive predictive value of mechanical interruption of atrial tachycardia to reduce the number of ineffective radiofrequency applications. BACKGROUND Radiofrequency catheter ablation has been… (More)
The Wide Field Camera 3 on the Hubble Space Telescope is currently one of the most widely used instruments for observing exoplanetary atmospheres, especially with the use of the spatial scanning technique. An increasing number of exoplanets have been studied using this technique as it enables the observation of bright targets without saturating the… (More)
The equilibrium between plasma and peritoneal dialysis fluid has been studies for 23 amino acids during peritoneal exchanges at dwell times up to 8 hours in patients on CAPD. It is demonstrated that equilibration is a particular process typical for each amino acid which after 8 hour is nearly complete only for Glycine, Alanine and Asparagine.
Studies in patients with uremia due to diabetes mellitus treated with CAPD show that the kinetics of amino acid equilibration between dialysate and plasma behave differently from those in patients with uremia of different etiology. Diabetics also have larger amino acid losses in dialysate.
It is very difficult to evaluate the ability of carrying out physical exercise in patients with rate responsive (RR) pacemaker (PM). However, the anaerobic threshold (AT) proved to be a useful parameter in the evaluation of cardiac function. The AT can be easily reproduced and not influenced from emotional aspects of both the patient and the physician,… (More)
Amino acid losses in peritoneal dialyzate during CAPD were less than 2 g a day (15, 128 micrometers). CAPD does not correct the tyrosine/phenylalanine ratio in plasma and does not prevent accumulation of 3-methylhistidine.
A group of 13 patients on Continous Ambulatory Peritoneal Dialysis up to 18 months was studied. During the study period, Peritoneal Urea Clearance was stable. In all but 2 cases peritonitis did not depress the efficiency in clearing urea. When Peritoneal Urea Clearance was corrected for 1.73 m2 surface area, there was on the average an 11.8% increase over… (More)
BACKGROUND Cardiac resynchronization therapy (CRT) is useful for the treatment of severe congestive heart failure. Unfortunately up to 30% of patients could be non-responders. The aim of our study was to find parameters to predict responsiveness to CRT. METHODS Fifteen patients (9 males, 6 females, mean age 67.3 +/- 7.8 years, range 52-83 years) with… (More)
