Primary intramuscular hydatidosis of supraspinatus muscle.

Abstract Hydatid disease of the muscle is very rare and represents approximately 3% of all patients with hydatidosis. Since the infection closely resembles a soft-tissue tumor on clinical examination, the preoperative radiologic diagnosis is very important to avoid biopsy. We report an unusual case of primary intramuscular hydatidosis with its magnetic resonance imaging appearance, clinical and pathological findings.

Hypermobility syndrome increases the risk for low bone mass

Few studies on the benign joint hypermobility syndrome suggest a tendency toward osteopenia, but there are conflicting results. We assessed bone mineral density in pre-menopausal women with hypermobility. Twenty-five consecutive Caucasian women diagnosed with benign hypermobility syndrome by Beighton score and 23 age- and sex-matched controls were included in the study. Age, menarch age, number of pregnancies, duration of lactation, physical activity and calcium intake were questioned according to European Vertebral Osteoporosis Study Group (EVOS) form. All subjects were pre-menopausal and none of them were on treatment with any drugs effecting bone metabolism or had any other systemic disease. No statistically significant difference was found for body mass index, menarch age, number of pregnancies, duration of lactation, calcium intake, calcium score and physical activity score between the two groups. Total femoral and trochanteric bone mineral density and t and z scores were significantly lower in hypermobile patients compared to the control group. Ward’s triangle and femoral neck z scores were also found to be significantly low in hypermobile patients (p<0.05). Significant negative correlations were found between the Beighton scores and trochanteric BMD, t and z scores (r=−0.29, r=−0.30, and r=−0.32) in hypermobility patients. Low bone mass was more frequently found among subjects with hypermobility (p=0.03). Hypermobility was found to increase the risk for low bone mass by 1.8 times (95% confidence interval 1.01–3.38). Our study suggests that pre-menopausal women with joint hypermobility have lower bone mineral density when compared to the controls and hypermobility increases the risk for low bone mass.

Lung parenchyma changes in ankylosing spondylitis: demonstration with high resolution CT and correlation with disease duration.

OBJECTIVE To analyze the spectrum of the lung parenchyma changes in ankylosing spondylitis (AS) with high resolution computed tomography (HRCT) and correlate the findings with disease duration. MATERIAL AND METHODS Twenty patients (18 male, 2 female) with the diagnosis of AS according to New York criteria were included in the study. None of the patients had history of tuberculosis, prolonged inorganic dust exposure and hospitalization for pneumonia. Seven of the patients were smokers, three patients were ex-smokers, and 10 patients were nonsmokers. The patients were assigned to three groups depending on disease duration. Group 1: patients with disease duration <or=5 years (N: four patients), group 2: patients with disease duration >or=6 years but <or=10 years (N: four patients), group 3: patients with disease duration >or=11 years (N: 12 patients). HRCT and pulmonary function tests (PFT) were performed in all patients. RESULTS HRCT demonstrated pathology in 17 patients (85%). Two patients in group 1, 4 patients in group 2 and 11 patients in group 3 had pulmonary parenchyma changes. Emphysema (9/20), septal thickening (9/20) and pleural thickening (9/20) were the most common changes followed by nodule (8/20) and subpleural band formation (7/20). Three patients had apical fibrosis (AF). Septal and pleural thickening (both 4/10) were the most common changes when only nonsmokers were considered. Among nine patients with emphysema three were nonsmokers. CONCLUSION There is a wide spectrum in pulmonary parenchyma changes in AS. These changes begin in early stages of the disease and increase with disease duration. Although smoking complicates the spectrum of changes in pulmonary parenchyma, they are predominately in the form of interstitial inflammation.

Indirect MR arthrography of the shoulder in detection of rotator cuff ruptures.

Abstract The aim of this study was to compare the efficacy of indirect MR arthrography images obtained following intravenous contrast injection and conventional MR imaging in the diagnosis of rotator cuff tears. Twenty-four patients with clinically suspected rotator cuff disease were examined. Conventional MR images and post-contrast indirect MR arthrography images were obtained. All images were evaluated in a blinded fashion by two musculoskeletal radiologist. Results were than analyzed depending on surgical output. The correlation coefficient (Spearman rank correlation test) and the kappa values for agreement between surgery and imaging techniques were calculated. The correlation coefficients between indirect MR arthrography and surgery for reader 1 and reader 2 were 0.9137 and 0.9773, respectively. Whereas the agreement between conventional MR imaging and surgery was moderate (ϰ = 0.383–0.571), the agreement between indirect MR arthrography and surgery was excellent (ϰ = 0.873–0.936). We suggest the use of indirect MR arthrography technique when conventional MR images are equivocal in diagnosis of rotator cuff disease.

Anatomical and biomechanical evaluation of the tension band technique in patellar fractures

Tension band wiring for patellar fractures is common, but some recent reports refer to disadvantages of this approach. Our anatomical and biomechanical study focused on use of tension band techniques in patellar fractures. The anatomy of the patella and tendon insertion was examined with knee magnetic resonance imaging (MRI) and correlated with the technical requirements of the tension band. Tension band wiring over tendinous tissue was simulated and calculated with a cyclic biomechanical test on cow patellae. According to tension band templating on the MRI section, Kirschner wire insertion was needed for the tension band to turn over the tendinous tissue. The tension band became more stable while turning over less tendinous tissue and more adjacent bone surface. Nevertheless, cyclic loading tests indicate that all tension band applications in this study lose their initial stability. Excessive initial compression by the tension band resulted in bending of the Kirschner wire and thus reduction failure. For optimum stabilisation, tension force transfer should be done directly on bone or at least material that protects the tendon would be useful.RésuméLa tension des fils métalliques lors de l’ostéosynthèse par hauban des fractures de rotules est habituellement utilisée, mais certains travaux en montrent les désavantages. Cette étude anatomique et biomécanique a été centrée sur cette pratique du hauban dans les fractures de la rotule. L’anatomie de la rotule et des insertions tendineuses ont été étudiées et corrélées avec les nécessités de tension. La tension de ce hauban mis en place au dessus des structures tendineuses a été évaluée par des tests biomécaniques sur des rotules de vaches. Selon l’insertion des broches de Kirschner, après étude IRM, il est nécessaire de serrer les fils du hauban sur les structures tendineuses mais, ce hauban est beaucoup plus stable que les tissus tendineux adjacents à l’os. Cependant, les tests de mise en charge nous montrent que ces haubans perdent leur stabilité initiale dès qu’une tension importante entraîne une plicature des broches de Kirschner et un échec de la réduction. Pour une stabilisation optimum, les forces de serrage du hauban doivent être directement appliquées sur l’os ou, tout au plus, au niveau de l’insertion tendineuse au plus près du matériel.

Effects of Three- or Four-Cortex Syndesmotic Fixation in Ankle Fractures

BACKGROUND There is no study comparing how Weber type C ankle fractures treated with either three- or four-cortex syndesmotic fixation affects the structure of the syndesmosis. METHODS In a retrospective study, 46 patients were separated into two groups: 22 patients with three-cortex fixation and 24 patients with four-cortex fixation. All of the patients were evaluated clinically and radiographically at least 1 year after removal of the syndesmosis screws. RESULTS There were three types of joint space obliteration: type 1, synostosis on plain radiographs; type 2, an incomplete bony bridge on magnetic resonance imaging with normal plain radiographs; and type 3, fibrous obliteration of the joint space. Although obliteration of the joint space was significant (P < .005) after four-cortex fixation, radiologic results did not affect the clinical outcome. CONCLUSION Four-cortex fixation for diastasis after an ankle fracture should not be a routine procedure. We advocate three-cortex fixation because the clinical results are no different and there is less syndesmotic space obliteration postoperatively.

Sandblasting under Uncontrolled and Primitive Conditions in Turkey

Abrasive blasting involves forcefully projecting a stream of abrasive particles onto a surface, usually with compressed air or steam. Since silica sand is commonly used in this process, workers who perform abrasive blasting are often called sandblasters. A material with rough particles should be used in order to have a sufficient effect on resistant surfaces such as glass or metal. Mostly quartz (silicon dioxide=SiO 2 ) is forced by compressed air onto the target surface . Although the frequency of the procedure is declining, it is still applied in an uncontrolled fashion in small-scale workplaces (employing fewer than 10 workers). The application in narrow areas, the break up of the SiO 2 particles into smaller pieces when striking the surface and reuse of the same material, increase the respirable dust concentration and this leads to high risk of silicosis . In our country sandblasting is being done in smallscale workplaces, which would operate as contractors for bigger companies. The purpose of this procedure is to polish the surface of metal, which comes from foundries, and to make the glass dull. The structural features of all workplaces were similar to each other. Although they are in the framework of control mechanisms such as licensing procedures supervised by local public health centers and municipalities, data collection and occupational health & safety inspections and enforcements are not carried out effectively for smallscale companies, so that the actual magnitude of the occupational risks is not known. In view of these observations, this study was planned with the following aims: to evaluate the work environment and working conditions in small-scale sandblasting workplaces, and to detect the frequency of silicosis among these workers in Turkey.

Prevalence of spondyloarthritis in Turkish patients with inflammatory bowel disease

Rheumatic manifestations are the most common extraintestinal findings of inflammatory bowel disease (IBD), although there are wide variations among different studies. The only previous Turkish study reported a rather high prevalence of spondyloarthritis (SpA) in patients with IBD. We aimed to determine the frequency of SpA and ankylosing spondylitis (AS) in patients with IBD attending a gastroenterology clinic from a referral centre. The study was conducted in 122 patients with established diagnosis of IBD [28 with Crohn’s disease (CD) and 94 with ulcerative colitis (UC)]. A detailed medical history was obtained and a complete physical examination was performed in all the patients. Standard pelvic X-rays for examination of the sacroiliac joints were performed only when clinically indicated. The X-rays were read blindly by an experienced rheumatologist and reported according to the established grading system. The modified New York criteria were used to classify AS, and the European Spondyloarthropathy Study Group criteria for SpA. The prevalence of AS and SpA in patients with IBD was 8.2 and 28.7%, respectively. SpA was found to be significantly more common in the patients with CD compared to patients with UC, but the frequency of AS was not different between these two groups. There was no correlation between localisation or extent of the intestinal inflammation and presence of AS and SpA. A higher frequency of women was observed in patients diagnosed as SpA. Almost half of the patients with SpA (45.7%) had not been diagnosed before the study, although they had a history of IBP and/or peripheral arthritis. This study suggests that the prevalences of SpA and AS in Turkish patients with IBD are similar to those in many other populations. There may be a significant female predominance of SpA among patients with IBD.

Gorham disease: correlation of MR findings with histopathologic changes

Abstract. Gorham disease is a rare disorder of unknown etiology characterized by bone destruction and abnormal proliferation of thin-walled vascular channels including lymphatic capillaries. Starting monocentrically in a single bone, the angiomatous masses in this disease extend to adjacent bones and soft tissues without respecting articular barriers. Herein we report a case of Gorham disease with its MR and histopathologic appearance.

Articular, B-cell, non-Hodgkin’s lymphoma mimicking rheumatoid arthritis: synovial involvement in a small hand joint

Polyarticular joint manifestations as the predominant symptom of non-Hodgkin’s lymphoma (NHL) are quite rare. In the absence of peripheral lymph node and visceral involvement, lymphomas presenting as polyarthritis create a problem for the patients as another rheumatic disease. We present a case that had been diagnosed with rheumatoid arthritis because of symmetrical articular symptoms. The patient later developed severe pain and marked swelling in her right fourth finger, and a diagnosis of septic arthritis and osteomyelitis complicating rheumatoid arthritis was assumed. The final diagnosis of NHL with synovial involvement could be made only after histopathologic examination of a biopsy specimen obtained from the amputated finger. This is the first case report demonstrating direct synovial involvement of a small joint in a patient with NHL presenting with polyarthritis. Articular and periarticular involvement of multiple joints shown by MRI in this patient suggests that direct synovial involvement may be responsible for the polyarticular symptoms in such patients.
