BACKGROUND Persistent creatine kinase elevation is occasionally encountered in subjects without any clinical manifestation of a neuromuscular disorder or any condition known to be associated with increased serum CK levels. It is still unresolved whether extensive investigations and specifically a muscle biopsy should be performed in clinically normal individuals with elevated CK levels. OBJEC...
Background: Injury extent and optimal management of asymptomatic urinary stones remain unclear, though they can be removed by almost any version of surgical management that is applicable to symptomatic stones. Objective: To compare the general characteristics, surgical outcomes, safety and postoperative renal functional changes between symptomatic and asymptomatic urolithiasis treated with surg...
BACKGROUND Chronic obstructive pulmonary disease (COPD) has a variable natural history and not all individuals follow the same course. This study aimed to identify the prevalence and characteristics of asymptomatic COPD patients from a population-based survey in China. METHODS A multistage cluster sampling strategy was used in a population from seven different provinces/cities. All residents ...
The clinical significance of asymptomatic bronchial hyperresponsiveness (BHR) is not well-known. The aim of this study was to explore, in a cross-sectional analysis, the characteristics of adolescent subjects with asymptomatic BHR, as compared to nonhyperresponsive subjects and those with symptomatic BHR. The subjects were selected by date of birth from the register of general practitioners. Th...
OBJECTIVE Both asymptomatic and symptomatic Clostridium difficile carriers contribute to new colonizations and infections within a hospital, but current control strategies focus only on preventing transmission from symptomatic carriers. Our objective was to evaluate the potential effectiveness of methods targeting asymptomatic carriers to control C. difficile colonization and infection (CDI) ra...
BACKGROUND Arterial flow velocity changes on transcranial Doppler can reflect changes in cerebral flow during position-induced ischemia if obtained during short-term monitoring of positional changes. SUBJECTS AND METHODS Our multicenter group monitored symptomatic and asymptomatic arteries in patients with recurrent neurological deficits during positional changes and documented intracranial a...
The purpose of this study was to evaluate the difference between disc and condyle position between temporomandibular joints (TMJs) without disc displacement (DD) in asymptomatic volunteers, and patients who have DD in contralateral joints, respectively unilateral DD. Secondly, there were two TMJ groups which consisted of measurements from patients' symptomatic DD and volunteers with asymptomati...
In this paper we uses The Differential pulse code modulation (DPCM) to remove the unused bit in the image for image compression. In this paper we compare the compressed image for 1 and 3 bit/pixel using DPCM and also compare the estimation error. We decrease the compressed image distortion and the estimation error. The PMSE in 3bit/pixel DPCM less 9-10 dB compare to 1bit/pixel DPCM. KeywordsNyq...
