prosthetic joint infection (pji) is a calamitous complication with high morbidity and substantial cost. the reported incidence is low but it is probably underestimated due to the difficulty in diagnosis. pji has challenged the orthopaedic community for several years and despite all the advances in this field, it is still a real concern with immense impact on patients, and the healthcare system....

Joint replacement is currently on the rise with a high community burden. A registry was designed to evaluate the costs,possible complications, and rate of revisions as well as finding the most effective techniques, risk factors associatedwith poor results, indications for revision surgeries, and also demographic evaluation of patients undergoing jointreplacement surgery in Iran. Level of eviden...

objectives: to investigate the clinical efficacy of physiotherapy with and without superficial dry needling on patients with knee pain; patellofemoral pain syndrome. methods: a randomized clinical trial conducted in 2015, tehran, iran. of patients with patellofemoral pain syndrome, thirty-four subjects were randomly divided into two groups (17 in each group). group a was subjected to physiother...

conclusions physicians should be aware of the signs and symptoms of different pain sources to prevent misdiagnosis and maltreatment. introduction fracture of the styloid process (sp) of the temporal bone is a rare traumatic injury in normal individuals who are not suffering from eagle’s syndrome. diagnosis and management of this problem requires comprehensive knowledge about its signs and sympt...

joint flexibility is a very important factor to consider in the controller design for robot manipulators if high performance is expected. most of the research works on control of flexible-joint robots in literature have ignored the actuator dynamics to avoid complexity in controller design. the problem of designing nonlinear controller for a class of single-link flexible-joint robot manipulator...

abstract   background: different methods of surgical treatment for acromioclavicular(ac) joint injury were considered in the literature. the purpose of the study was to compare intra- articular ac repair technique with the extra-articular coracoclavicular repair technique for the patients with rockwood type iii and vac joint injury when indicated.   methods: nineteen consecutive patients with r...

background: pemphigus is an autoimmune bullous disease and it is unclear what triggers and deteriorates it. the current study aimed to evaluate whether increasing the igg antibody titer represents a good indicator of the pemphigus recurrence. objectives: the current study aimed to evaluate whether increasing igg titer is an indicator of the expected recurrence. patients and methods: the current...

Ehlers Danlos syndrome (EDS) is an inherited connective tissue disease due to impaired collagen metabolism. Joint hypermobility and skin hyper extensibility are the major findings. Six types of EDS are recognized. Type I or Gravis type is characterized by skin hyperextensibility, joint hypermobility, skin splitting autosoml dominancy inheritance, preterm premature rupture of membrane (PPROM) an...

in this note we characterize polynomial numerical hulls of matrices $a in m_n$ such that$a^2$ is hermitian. also, we consider normal matrices $a in m_n$ whose $k^{th}$ power are semidefinite. for such matriceswe show that $v^k(a)=sigma(a)$.
