November 21, 2003   Lack of relationship of calcium and vitamin D intake to bone mineral density in premenopausal women with inflammatory bowel disease - American Journal of Gastroenterology Conclusion: The results show that, on average, premenopausal women with IBD have less than the recommended intake for calcium and vitamin D. However, this does not seem to influence BMD. Calcium and vitamin D intake is not a predictor of bone status in premenopausal women with IBD...   Effect of firmness of mattress on chronic non-specific low-back pain: randomised, double-blind, controlled, multicentre trial - The Lancet Conclusion: A mattress of medium firmness improves pain and disability among patients with chronic non-specific low-back pain... November 20, 2003   Dynamic Contrast-Enhanced Magnetic Resonance Imaging of Osteoporotic Vertebral Fracture - Spine Conclusion: The subsequent progression of vertebral collapse tended to increase the greater the noncontrast area in the injured vertebrae in dynamic magnetic resonance imaging. Dynamic magnetic resonance imaging appears to be useful in predicting the progression of collapse of fractured vertebrae...

November 19, 2003   Extracorporeal Shock Wave Therapy for the Treatment of Chronic Calcifying Tendonitis of the Rotator Cuff: A Randomized Controlled Trial - JAMA Conclusion: Both high-energy and low-energy ESWT appeared to provide a beneficial effect on shoulder function, as well as on self-rated pain and diminished size of calcifications, compared with placebo. Furthermore, high-energy ESWT appeared to be superior to low-energy ESWT... November 07, 2003   Anti-neutrophil cytoplasmic antibodies in patients with rheumatoid arthritis: clinical, biological, and radiological correlations - Joint, Bone, Spine Our results confirm that ANCA of various specificities (mainly a-ANCA) occur in a minority of RA. However, those ANCA were not associated with more severe RA, including the 6/85 patients positive for MPO (who were all free from vasculitis). The over-representation in RA sera of a-ANCA, as compared to p-ANCA, should be further studied... November 06, 2003   Use of advanced imaging modalities for the differential diagnosis of pathoses mimicking temporomandibular disorders - Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics Conclusion: When diagnosing patients with TMD symptoms, we must consider the possibility of unusual causes, including tumors and infections or inflammations. Furthermore, in addition to usual TMD treatment procedures, an advanced radiologic examination should be performed to aid in the differential diagnosis of all patients with unceasing pain and mouth-opening limitation...   Case Report: Dorsal dislocation of the first metatarsophalangeal joint associated with fractured second metatarsal head: a case report and literature review - Foot and Ankle Surgery Conclusion: The papers principle message is that significant injuries to the MTPJ can be missed with radiological features mimicking common orthopaedic pathology. Subtle signs may reveal significant injury when imaged further. The discussion features a review of current literature...   Confirmation of the Early Prognostic Value of Bone Scanning and Pinhole Imaging of the Hip in Legg-Calvé-Perthes Disease - The Journal of Nuclear Medicine Conclusion: This study confirms the high prognostic value of bone scanning in LCP as reported by Conway’s group not only in terms of the accuracy of the classification but also in terms of the short time in which the prognostic information can be obtained. Thus, we propose that bone scanning be used as part of routine care for the management of LCP...   Adhesive Capsulitis of the Shoulder: Diagnosis Using Magnetic Resonance Arthrography, with Arthroscopic Findings as the Standard - Journal of Computer Assisted Tomography Conclusion: On MR arthrography, thickening of the joint capsule and synovium and diminished filling ratio of the axillary recess to posterior joint cavity appeared to be useful diagnostic criteria for the diagnosis of adhesive capsulitis of the shoulder...

November 05, 2003   MR goes behind scenes of ballet dancers' pain - Diagnostic Imaging Radiologists from the Chelsea and Westminster Hospital in London reviewed 20 MR scans of 17 dancers over a two-year period. Posterior impingement proved a common problem, with 12 scans revealing typical signs of this complaint. Four of these scans also showed signs of os trigonum, which is known to exacerbate the problem...   Root-canal preparation with FlexMaster: canal shapes analysed by micro-computed tomography - International Endodontic Journal Conclusion: FlexMaster instruments shaped curved and narrow root canals in maxillary molars to sizes 40 and 45 without significant shaping errors. Canal anatomy had an insignificant impact on preparation, indicating that FlexMaster instruments were able to shape ‘constricted’ canals as well as ‘wide’ ones...   Coronal pulp size in molars: a study of bitewing radiographs - International Endodontic Journal Conclusion: Even teeth with shallow occlusal restorations had reduced pulp spaces. There were significant differences in pulp and crown dimensions between the teeth of Mongoloid patients and those of other patients... November 04, 2003   Sonography spots rheumatoid arthritis erosions in joints - Diagnostic Imaging Rheumatoid arthritis is a chronic inflammatory arthropathy of unknown etiology. It is, unfortunately, common and may affect an estimated 1% of the adult population worldwide. Women are affected more commonly than men, with the female to male ratio reported as high as three to one. RA usually presents with an insidious onset in the third to sixth decades of life but demonstrates de novo occurrence as late as the ninth decade...

November 03, 2003   Relation Between Body Mass Index and Radiological Progression in Patients with Rheumatoid Arthritis - Journal of Rheumatology Conclusion: Together with the presence of HLA-DR4 shared epitope and erosive disease at study entry, a low BMI at the beginning of RA was found in association with higher radiographic progression in RA. Accordingly, BMI could be of interest as a sensitive and inflammation-independent predictor for radiological outcome of RA...   Gene Transfer with Echo-enhanced Contrast Agents: Comparison between Albunex, Optison, and Levovist in Mice—Initial Results - Radiology Conclusion: Low-intensity ultrasound with echo-enhanced Optison induced efficient gene transfer unlike that with Albunex or Levovist...   Quantification of Bone Involvement in Gaucher Disease: MR Imaging Bone Marrow Burden Score as an Alternative to Dixon Quantitative Chemical Shift MR Imaging—Initial Experience - Radiology Conclusion: BMB is a reproducible semiquantitative scoring system that is easy to use. It combines MR imaging of both axial and peripheral bone marrow and shows a significant correlation with QCSI...   Rheumatoid Hand Joint Synovitis: Gray-Scale and Power Doppler US Quantifications Following Anti–Tumor Necrosis Factor– Treatment: Pilot Study - Radiology Conclusion: US is a feasible imaging modality for measurement of the response of RA small-joint synovitis to therapy...   Telangiectatic Osteosarcoma: Radiologic-Pathologic Comparison - Radiology Conclusion: CT and MR imaging findings of telangiectatic osteosarcoma often include thick nodular tissue (and matrix mineralization at CT) in a largely hemorrhagic and/or necrotic osseous lesion with an associated soft-tissue mass, which allows distinction from aneurysmal bone cyst...   Case Report: Dorsal dislocation of the first metatarsophalangeal joint associated with fractured second metatarsal head: a case report and literature review - Foot and Ankle Surgery Conclusion: The papers principle message is that significant injuries to the MTPJ can be missed with radiological features mimicking common orthopaedic pathology. Subtle signs may reveal significant injury when imaged further. The discussion features a review of current literature...
