Background and Objective: Muscle weaknesse particularly in association with quadriceps muscle is known as a risk factor in the development and progression of knee osteoarthritis (KOA). The objective of this study was to compare quadriceps muscle strength (QMS) between asymptomatic controls and KOA patients and to elucidate its relationship with knee pain and radiographic changes. Materials a...
introduction: the aim of this study was to identify the reasons for failure in clinical, radiographic, and histopathologic diagnoses as well as their interactions with each other. methods: personal information and lesion characteristics of 51 patients with central or peripheral exophytic lesions were collected in mashhad dental school. specialists determined clinical and radiographic diagnoses ...
background: in this experimental study, the radiographic and biomechanical characteristics of osteoperforated rabbit tibia during bone repair period were investigated. materials and methods: using dental drills, 2 mm holes were drilled at the mid-shaft of right tibia in 12 new zealand white rabbits. the left tibia was intact and selected as the control. x-rays of the left and right tibias were ...
BACKGROUND Studies have suggested that the symptoms of knee osteoarthritis (OA) are rather weakly associated with radiographic findings and vice versa. Our objectives were to identify estimates of the prevalence of radiographic knee OA in adults with knee pain and of knee pain in adults with radiographic knee OA, and determine if the definitions of x ray osteoarthritis and symptoms, and variati...
The aim of the present study was to determine the percentage of dentists who use radiographic examination on the initial appointment, and establish the relation between the use of periodontal probe and graduation year. Dentists were interviewed in their private offices in three cities in Rio Grande do Sul. They were asked about the routine use of radiographic examination and, if applicable, wha...
BACKGROUND The optimal means of quantifying change on chest radiography in sarcoidosis is uncertain. In current guidelines, the role of serial measurement of carbon-monoxide diffusing capacity (DLco) remains undefined and the prevalence of discordance between serial chest radiographic change and pulmonary function tends is unknown. OBJECTIVE To identify and explore key uncertainties in the mo...
Digital dental radiographic imaging is considered to be as diagnostically accurate as conventional film-based radiography. In addition, many digital radiographic systems offer various image enhancements that may aid in image interpretation. However, neither type of radiographic imaging technique perfectly correlates radiographic diagnoses with clinical findings. Moreover, visual digital enhance...
OBJECTIVE To investigate whether patients with severe radiographic osteoarthritis (OA) have a different outcome at one year after total hip replacement than patients with moderate radiographic OA. To investigate sex related differences in preoperative radiographic and self reported status and in postoperative outcome. METHODS 184 patients (96 women) with a mean age at surgery of 71.4 years (5...
The ejection fraction is one of the most widely used measurements of left ventricular systolic function. Angiographic measurement of ejection fraction is based on determination of roentgenographic magnification and calculation of end-diastolic and end-systolic volumes, assuming a prolated ellipse. Because it is simple and radiographic magnification may not have been determined, some laboratorie...
Let f and g be distributions and let gn = (g ∗ δn)(x), where δn(x) is a certain sequence converging to the Dirac-delta function δ(x). The noncommutative neutrix product f ◦ g of f and g is defined to be the neutrix limit of the sequence { f gn}, provided the limit h exists in the sense that N-limn→∞〈 f (x)gn(x),φ(x)〉 = 〈h(x),φ(x)〉, for all test functions in . In this paper, using the concept of...
