PURPOSE OF REVIEW Surgical and nonsurgical treatment of arthritis is a rapidly developing and evolving field. It is vital for clinicians to keep up on the latest advances. This review focuses on clinical trials or large prospective studies over the past year that evaluated orthopedic surgical techniques for the treatment of arthritis and new nonsurgical therapies that may prevent the need for s...

Positioning 3R manipulators may have two or four inverse kinematic solutions (IKS). This paper derives a necessary and sufficient condition for 3R positioning manipulators with orthogonal joint axes to have four distinct IKS. We show that the transition between manipulators with 2 and 4 IKS is defined by the set of manipulators with a quadruple root of their inverse kinematics. The resulting co...

The orthopaedic joint replacement team is very different today than even a decade ago. Although the surgeon is still the leader, excellent outcomes depend on the help and interactions of physician assistants; nurse practitioners; office, floor, and operating room nurses; surgical technicians; physical and occupational therapists; and medical assistantsdto name but a few. Medical student and res...

Shoulder joint replacement, or arthroplasty, is indicated in cases where arthritis or trauma has resulted in severe joint damage that in turn causes increased pain and decreased function. However, shoulder arthroplasty is less successful than hip and knee replacement, mostly due to the complexity of the shoulder joint and the resultant complexity of the replacement operation. In this paper we p...

BACKGOUND The term 'joint modelling' is used in the statistical literature to refer to methods for simultaneously analysing longitudinal measurement outcomes, also called repeated measurement data, and time-to-event outcomes, also called survival data. A typical example from nephrology is a study in which the data from each participant consist of repeated estimated glomerular filtration rate (e...

Background: The ultimate goal of the treatment of infectious knee arthritis is to protect the articular cartilage fromadverse effects of infection. Treatment, however, is not always hundred percent successful and has a 12% failurerate. Persistent infection is more likely to happen in elderly patients and those with underlying joint diseases,particularly osteoarthritis. Eradica...

although triple (omeprazole, amoxicillin, and metronidazole) and quadruple (omeprazole, tetracycline, metronidazole, and bismuth subcitrate) therapeutic regimens for h. pylori eradication has been studied much in the general population, there is a lack of data in renal transplanted patients. so, this study aimed at comparing regimens in these patients who were considered being immunocompromised...

A Steiner quadruple system (X, B) is said to be (1, 2)-resolvable if its blocks can be partitioned into r parts such that each point of X occurs in exactly two blocks in each part. The necessary condition for the existence of (1, 2)-resolvable Steiner quadruple systems RSQS(1, 2, v)s is v ≡ 2 or 10 (mod 12). Hartman and Phelps in [A. Hartman, K.T. Phelps, Steiner quadruple systems, in: J.H. Din...

[Purpose] The purpose of this study was to elucidate changes in balance strategy during pregnancy from a kinematics perspective. [Subjects] Eight pregnant women and eight non-pregnant women participated. [Methods] A 3D motion analysis system, two force plates, and 10 infrared cameras were used to measure the kinematics of the balance strategy. The 3D motion analysis system was used to analyze p...

background the use of quadruple therapy for helicobacter pylori ( h. pylori ) eradication is a highly efficacious, gold standard regimen. however, according to a num­ber of studies, this regimen has numerous compliance problems and adverse effects. in the current study we have evaluated the h. pylori eradication rate following a quadruple therapy that included omeprazole, bismuth subcitrate, am...
