Introduction: Scintigraphy has been considered as a useful tool in the assessment of meniscal tears. Our objective was to assess the accuracy of single photon emission tomography (SPECT), using MRI as the gold standard, in the diagnosis of meniscal tears. Materials and Methods: Between January 2003 and February 2005, 45 patients were studied with SPECT and MRI. Results: The respective sen...
A study was undertaken to determine whether a significantly different clinical outcome could be expected following nonoperative treatment of acute partial anterior cruciate ligament (ACL) tears from that of complete tears. A detailed follow-up of 107 patients with arthroscopically confirmed tears was obtained; 72 were complete tears and 35 partial. The overall results in those with partial tear...
OBJECTIVE To assess the diagnostic performance of MR arthrography in the diagnosis of the various types of partial-thickness rotator cuff tears by comparing the MR imaging findings with the arthroscopic findings. MATERIALS AND METHODS The series of MR arthrography studies included 202 patients consisting of 100 patients with partial-thickness rotator cuff tears proved by arthroscopy and a con...
The arthroscopic study of knee joint is of outstanding interest in assessment of knee complaints. The present article describes the results of arthroscopic examination of 100 patients (Mean age 29.4 years 82% male) evaluated from 1996 to 1997 in Imam Khomeini hospital of Tehran. Sport injury was the most prevalent cause of referral (40%). The 2 most frequent complaints were knee pain (94%) and ...
Meniscal root tears are defined as radial tears located within 1 cm from the meniscal attachment or a bony rootavulsion. This injury is biomechanically comparable to a total meniscectomy, leading to compromised hoop stressesresulting in decreased tibiofemoral contact area and increased contact pressures in the involved compartment.These changes are detrimental to the articular cartilage and ult...
Thirty-five of the 49 patients also underwent fluoroscopy-guided 3T MR arthrography of the wrist joint using a gadolinium/saline contrast mix. Arthroscopy found TFCC tears in 22 patients, scapholunate tears in 18, and lunatotriquetral tears in 11. Nineteen TFCC tears, 16 scapholunate tears, and nine lunatotriquetral tears were seen on 3T MRI. There were no false-positive readings on MRI compare...
Collagenous colitis, which is clinically characterized by chronic non-bloody diarrhea, is a variant of microscopic colitis. It can be diagnosed on histological grounds, with thickening of the subepithelial collagen layer [1–3]. The colonic mucosa is usually endoscopically normal, although minor abnormalities such as edema or erythema can be seen [2,3]. Serious complications are rare. A 69-year-...
Although the host immune response to the 60-kDa chlamydial heat shock protein (hsp60) has been implicated in trachoma pathogenesis, no studies have examined mucosal immune responses to hsp60 in populations for which chlamydia is endemic. Tears and sera from Nepali villagers were reacted against hsp60 fusion proteins, whole hsp60, and the major outer membrane protein (MOMP). Tears from villagers...

This report shows that the direction of polarization of attached mammalian cells determines the direction in which they move. Surfaces micropatterned with appropriately functionalized self-assembled monolayers constrain individual cells to asymmetric geometries (for example, a teardrop); these geometries polarize the morphology of the cell. After electrochemical desorption of the self-assembled...
