[Usefulness of ultrasonography and color Doppler sonography in the diagnosis of major salivary gland diseases].

The algorithm for imaging of the salivary glands depends on the clinical scenario with which the patient presents to the clinician. Ultrasound has been increasingly used in recent years and thanks to high performance, easy to use apparatus, it can now be used for exploration of the salivary glands. This non invasive, painless and relatively inexpensive examination provides rapid visualisation of the salivary glands and is a useful adjunct to computed tomography and magnetic risonance imaging examination, particularly in tumour pathology. In recent years, publications have highlighted the potential uselfulness of salivary gland ultrasonography as a simple and non-invasive adjunctive test for the detection of gland involvement in Sjögren's syndrome (SS). SS is a chronic inflammatory disease of the salivary glands characterised by focal lymphocytic infiltrates that cause progressive destruction of the acinar structures. The findings of a previous study lead us to believe, in agreement with other examiners, that semiquantitative assessment of ultrasonographic images of the salivary glands is a sensitive and very useful means of evaluating salivary involvement in SS. Color Doppler sonography is a recently introduced method which makes it possible to evaluate intra- and perilesional vascularization and to perform a hemodynamic study of the area being explored. The color Doppler sonography can provide a useful adjunct to conventional ultrasound, increasing diagnostic accuracy in submandibular- parotid masses and to analyze physiologic changes that occur during salivary stimulation in normal subjects and the flow alterations that occur in diseased glands of SS patients. This article reviews the normal ultrasound anatomy of the salivary glands along with lithiasic, inflammatory, tumoral, and autoimmune disease such as SS.

[Italian consensus on EULAR recommendations 2005 for the management of hip osteoarthritis].

The recommendations for the management of osteoarthritis (OA) of the hip were proposed by EULAR in 2005. Among the most important objectives of the expert charged to provide these recommendations were their wide dissemination and implementation. Thus, the information generated can be used by each individual country to produce their own set of management guidelines and algorithms for treatment in primary care. According with that previously executed for the EU-LAR recommendation 2003 for the knee, the Italian Society of Rheumatology (SIR) has organised a Consensus on the EULAR recommendations 2005 for the management of hip OA. To obtain an acceptability as large as possible, the group of experts was composed by many physicians interested in the management of hip OA, including Orthopaedics, Rheumatologists, Physiatrists, and General Practitioners. Main aim of the Consensus was to analyse the acceptability and applicability of the recommendations according to own experience and local situations in the Italy. The results of this Consensus have demonstrated that a large majority of the EULAR recommendations are endorsed by the Italian experts. Furthermore, the final document of the Italian Consensus clearly indicated the need that the specialists involved in the management of hip OA strongly encourage the dissemination of the EULAR 2005 recommendations also in Italy.

Intralesional therapy in carpal tunnel syndrome: a sonographic-guided approach.

OBJECTIVE: The aim of this pictorial essay is to show a representative example of sonographic-guided injection in carpal tunnel syndrome associated with tenosynovitis of the finger flexor tendons. METHODS: Images were obtained using a real-time ultrasound system (AU4-idea; Esaote Biomedica, Genoa, Italy) equipped with a 13-MHz linear transducer. The best injection site was detected using a fine metal clip placed between the skin and the transducer. The images here were obtained in a patient with rheumatoid arthritis and carpal tunnel syndrome secondary to tenosynovitis of the finger flexor tendons. RESULTS: Steroid injection within the carpal tunnel under sonographic control was easily performed. All steps of the needle placement within the widened tendon sheath were carefully evaluated on the monitor screen. Marked clinical improvement occurred shortly thereafter (3 days) and increased over the next 6 weeks. CONCLUSION: A detailed assessment of the carpal tunnel and a correct, safe placement of the needle for steroid injection can be quickly performed under sonographic guidance.

[Sonographic findings for synovial fluid].

OBJECTIVE: The aim of this pictorial essay was to evaluate the sonographic features of synovial fluid in patients with arthritis. METHODS: Sixty-nine patients with active synovitis (rheumatoid arthritis, psoriatic arthritis, osteoarthritis, septic arthritis, crystal arthropathies, post-traumatic arthritis) were studied. Sonographic evaluation was performed with a AU-5 Harmonic, Esaote Biomedica (Genoa, Italy) equipped with a 10-14 MHz broadband linear transducer and a Diasus Dynamic Imaging Ltd.(Livingston, Scotland UK) equipped with a 8-16 MHz broadband linear transducer. RESULTS: Six main different sonographic patterns were detected: 1) Anechoic: increased amount of homogeneous anechoic synovial fluid (exudative synovitis). 2) Cloudy: echogenic structures (proteinaceous material). 3) Mixed: anechoic synovial fluid and proteinaceous material. 4) "Snow-storm" aspect: multiple mildly and heterogeneous echoic spots (9 out of 10 patients with acute gouty synovitis). 5) Dotted: multiple sparkling hyperechoic dots without posterior acoustic shadow (10 out of 12 patient with chondrocalcinosis). 6) Granular: irregular turbid aspect of the synovial fluid. It was present in 3 patient with septic arthritis. CONCLUSIONS: The results of this study indicate that high resolution ultrasonography is able to detect different features of synovial fluid. Further studies are needed to assess both sensitivity and specificity of ultrasonography in "in vivo" synovial fluid examination.

Development of a functional disability measurement tool to assess early arthritis: the Recent-Onset Arthritis Disability (ROAD) questionnaire.

OBJECTIVE: To develop a self-administered questionnaire, the ROAD (Recent-Onset Arthritis Disability), to probe physical disability in Italian patients with early arthritis (EA) of less than one year's duration. METHODS: The development of the ROAD follows a series of major steps: (1) identification of a specific patient population, (2) item pool development, (3) item reduction, (4) internal consistency, (5) pre-testing of the prototype instrument, and (6) a validation study which results in determination, reliability, validity and responsiveness. In this study we have verified the first five steps. Pre-defined areas of disability were culled from eight existing Italian version arthritis-specific questionnaires, and three generic global health measurement tools. Semi-structured interviews helped to derive a 76-item pool from an initial group of 122 items. This questionnaire was administered to 78 EA patients. RESULTS: For scale generation, a combination of frequency importance product (FIP = frequency x mean relevance score) and factor analysis was applied. The top 20 items based on the FIP were then subjected to further analysis. Each question was correlated with every other question. This allowed us to eliminate 8 questions that were therefore highly correlated and were measuring the same concept. The final instrument has 12 items, representing a combination of symptoms that are common, frequently recurring and of general importance to EA patients. Factor analysis provides a 3-factor health status model explaining 70.1% of the variance. The upper extremity function (5 items) is loaded on the first factor, which explains 45.4% of the total measured variance. The lower extremity function (4 items) formed the second factor (14.2% of the total variance). The third factor was determined by activities of daily living/work (3 items) and explain 10.5% of the total variance. The score of the different subscales can be presented graphically as a ROAD profile. CONCLUSION: Using a traditional development strategy, we have constructed a self-administered instrument for measuring physical functioning in patients with EA. The next stage includes reliability, validity and responsiveness testing of the 12-item questionnaire.

Measuring functional disability in early rheumatoid arthritis: the validity, reliability and responsiveness of the Recent-Onset Arthritis Disability (ROAD) index.

OBJECTIVE: Disability has been identified as a core outcome measure in rheumatoid arthritis (RA). The aim of this study was to test the Recent-Onset Arthritis Disability (ROAD) questionnaire for validity, reliability and responsiveness in Italian patients with early RA. METHODS: The psychometric properties of ROAD were tested in 159 patients with early RA, mean age 54.7 (+/- 8.8), 74.3% women, mean disease duration 14.5 months (+/- 1.9 months). All completed the ROAD, the Medical Outcomes Study SF-36 Health Survey (SF-36), the Health Assessment Questionnaire (HAQ) and the patient global assessment (PGA) of functional disability twice, in order to test for validity and responsiveness. Of the 159 patients who completed the health status instruments on two occasions, 121 were included in the responsiveness analyses. The test-retest reliability of the ROAD questionnaire was calculated using intraclass correlation coefficients (ICCs) and the Bland and Altman method on 77 patients who completed the questionnaire twice over an interval of one week. Construct validity was assessed using Spearman's correlations, while responsiveness was evaluated by 3 different methods: (1) effect size (the mean difference between the baseline scores and thefollow-up scores divided by the standard deviation of the baseline scores); (2) standardized response mean (the mean change in scores divided by the standard deviation of the change in scores); (3) receiver operating characteristics (ROC) curve analysis. RESULTS: ROAD fulfilled the established criteria for validity, reliability and responsiveness. In comparison with the SF-36, the expected correlations were found when comparing items measuring similar constructs, thus supporting the convergent construct validity. Significant correlations were seen between ROAD scores and HAQ scores (rho = 0.372), SF-36 physical component summary (PCS) (rho = -0.413), PGA functional disability (rho = 0.417), pain (rho = 0.639), Ritchie index (rho = 0.357), number of swollen joints (rho = 0.387), patient and physician assessment of disease activity (rho = 0.467 and 0.323, respectively), and Disease Activity Score (rho = 0.476). Test-retest reliability was satisfactory, with ICCs of 0.927 (upper extremity function), 0.892 (lower extremity function), and 0.851 (activity of daily living/work). Bland-Altman plots confirmed this finding. The results of responsiveness analysis indicate that the ROAD subscales were slightly more sensitive to perceived change in functional disability than those of HAQ, SF-36 PCS, and PGA offunctional disability. CONCLUSION: Our data suggest that the ROAD index is a reliable, valid and responsive tool for measuring physical functioning in patients with early RA, and is suitable for use in clinical trials and daily clinical practice. Its generalizability and utility for assessing aggressive treatment and functional outcomes must now be evaluated in broader settings.

Prevalence of musculoskeletal conditions in an Italian population sample: results of a regional community-based study. I. The MAPPING study.

OBJECTIVE: The objective of the MAPPING study was to estimate the prevalence of musculoskeletal conditions in an Italian population sample. METHODS: Questionnaires were sent to a random sample of 3664 individuals aged 18 years and over, stratified for age and gender, selected from the practice lists of 16 general practices. Trained rheumatologists carried out structured visits in which subjects were asked about musculoskeletal symptoms and socio-demographic characteristics, and underwent a standardized physical examination. Cases were defined by previously validated criteria. RESULTS: A total of 2155 subjects participated in the study (response rate 58.8%). The overall prevalence of musculoskeletal conditions in the general adult population was 26.7% (95% CI 25.4-28.5), being significantly higher among women than men (p < 0.0001). Disease prevalence increased significantly with age (p < 0.0001). The most common disease group was symptomatic peripheral osteoarthritis (SPOA), with a prevalence of 8.95% (95% CI 6.81-10.7), followed by soft tissue disorders--STD (8.81%; 95% CI 7.16-10.29), low back pain--LBP (5.91%; 95% CI 4.89-6.89), and inflammatory rheumatic disease--IRD (3.06%; 95% CI 2.38-3.93). The estimated rates of disease prevalence were as follows: rheumatoid arthritis: 0.46% (95% CI 0.33-0.59); psoriatic arthritis: 0.42% (95% CI 0.31-0.61); ankylosing spondylitis: 0.37% (95% CI 0.23-0.49); polymyalgia rheumatica: 0.37% (95% CI 0.29-0.44); undifferentiated connective tissue disease: 0.14% (95% CI 0.09-0.21); crystal arthropathies, including gout 0.46% (95% CI 0.34-0.57) and chondrocalcinosis: 0.42% (95% CI 0.33-0.58); symptomatic knee osteoarthritis (OA): 5.39% (95% CI 3.41-7.99); hip-OA: 1.61% (95% CI 1.39-1.87); hand-OA: 1.95 (95% CI 1.22-2.48); fibromyalgia: 2.22% (95% CI 1.36-3.19); shoulder tendinitis/adhesive capsulitis: 3.06% (95% CI 2.11-4.09); carpal tunnel syndrome: 1.90% (95% CI 1.06-2.29), localized regional pain syndromes of the neck: 0.88% (95% CI 0.561.29), and lateral epicondylitis 0.74% (95% CI 0.47-1.33). CONCLUSIONS: The MAPPING study indicates that musculoskeletal conditions are common in the general adult population of Italy. These data are useful in planning the provision of healthcare.

Health-related quality of life in multiple musculoskeletal conditions: a cross-sectional population based epidemiological study. II. The MAPPING study.

OBJECTIVE: Musculoskeletal conditions are a major burden on individuals, health systems, and social care systems. The objective of the MAPPING study was to assess the impact of musculoskeletal conditions on health-related quality of life (HRQL) in an Italian population sample. METHODS: Trained rheumatologists carried out structured visits in which subjects were asked about musculoskeletal symptoms and socio-demographic characteristics, completed validated instruments for measuring HRQL, such as the Short Form 36 items status survey questionnaire (SF-36), the EUROQoL five item questionnaire (EQ-5D), and chronic pain severity (Chronic Pain Grade - CPG questionnaire), and underwent a standardized physical examination. We considered a sample size of 576 patients diagnosed as having had musculoskeletal conditions. For the purposes of this study, musculoskeletal diseases were classified into 4 diagnostic groups: inflammatory rheumatic diseases (IRD), symptomatic peripheral osteoarthritis (SPOA), low back pain (LBP), and soft tissue disorders (STD). Cases were defined by previously validated criteria. RESULTS: The 4 major musculoskeletal disease groups, compared to non-sufferers, significantly impaired all eight health concepts of the SF-36 in the following order of magnitude: IRD, SPOA, STD, and LBP. Similar results were found for EQ-5D. The most striking impact was seen for SF-36 physical measures. On multiple regression modelling the physical component (PCS) of the SF-36 was influenced by female sex, age, high BMI, and low educational level (all at a p level < 0.001), and by manual occupation (p = 0.028) and chronic co-morbidity (p = 0.035) in LBP In SPOA, factors influencing physical function were age (p = 0.0001), low educational level (p = 0.006), female sex (p = 0.028), and chronic co-morbidity (p = 0.037). Moreover, an association on chronic co-morbidity and low educational level (both at a p level < 0.001), age (p = 0.004), and manual occupation (p = 0.035) was found with IRD, as well as of chronic co-morbidity and low educational level (both at a p level < 0.001), female sex (p = 0.006) and high BMI (p = 0.036) with STD were also found. Similar results were found for EQ-5D. CONCLUSIONS: The MAPPING study indicates that musculoskeletal conditions have a clearly detrimental effect on the HRQL and one third of the adult population in Italy visited at least one physician for musculoskeletal problem in the past year. These results enable a comparison to be made of the burden of musculoskeletal conditions with that of other common chronic conditions.

Ultrasound imaging for the rheumatologist.

Over the last few years, technological advances have resulted in dramatic improvements in quality and resolution of ultrasonography (US), allowing it to become a very powerful tool in rheumatological clinical practice. Despite the fact that the impact of US on final diagnosis or therapeutic options for rheumatic patients has not yet been defined, there is now growing evidence that US improves clinical diagnosis and intervention skills. This review discusses the most important issues connected with the practice of US in rheumatology including: basic requirements, scanning technique, clinical applications, training and future developments. Moreover, it provides a general overview of both US anatomy and pathology relevant for the rheumatologist.

Ultrasound imaging for the rheumatologist. I. Ultrasonography of the shoulder.

Ultrasonography (US) has proved to be a useful diagnostic tool in patients with shoulder pain and/or limited range of motion. It allows careful assessment of a wide range of changes involving many different anatomic structures of the shoulder girdle, such as the rotator cuff tendons (tendonitis, tendon tears and calcific deposits), the long head of the biceps tendon (tenosynovitis, tendonitis, tears, rupture and displacement), the bursae (bursitis), the soft tissues of the gleno-humeral (synovial proliferation, joint effusion) and acromioclavicular joints (synovial proliferation and joint effusion). In addition, it is also a reliable tool in the evaluation of bony profiles detecting the presence of erosions and osteophytes. The use of high quality equipment and the application of a standard scanning protocol are mandatory for reliable US assessment of shoulder pathology.

Ultrasound imaging for the rheumatologist II. Ultrasonography of the hand and wrist.

The hand is one of the anatomical regions most frequently explored by ultrasonography (US) in rheumatology. The last generation US systems equipped with high frequency probes allow for a quick and accurate assessment of even minimal pathological changes in patients with rheumatic conditions affecting the small joints and the soft tissues of the hand and wrist. Several studies have demonstrated the great value of US imaging of the hand and wrist in rheumatology but there are still controversial issues which yet have to be adequately addressed, particularly with regard to US semi-quantitative evaluation of synovitis and bone erosions in patients with chronic arthritis. This paper provides the basic knowledge, reviews the available evidence and discusses the potential of US in the evaluation of the hand and wrist.

Ultrasound imaging for the rheumatologist III. Ultrasonography of the hip.

Ultrasonography (US) is a reliable and useful diagnostic tool for the assessment of hip pathology. It depicts changes within the coxo-femoral joint (synovitis, erosions, osteophytes) and in the adjacent peri-articular tissues (calcifications, tendonitis, enthesitis, bursitis) in many rheumatic diseases (rheumatoid arthritis, spondyloarthritis, osteoarthritis, polymyalgia rheumatica ) and in some orthopaedic disorders (septic arthritis, trauma, abscess, painful hip after arthroplasty). It is commonly used both in adults and in children. In the assessment of hip joint pathology, US exerts considerable diagnostic supremacy over physical examination. In fact, by virtue of its size and position, reliable physical examination of the hip is often difficult thus making US particularly useful as a bedside tool for the evaluation of a painful hip. Hip US has also proven to be of great practical benefit when performing aspiration and injection within the joint and in the periarticular soft tissues. The relatively limited acoustic windows available to the US beam is the principal limitation to hip US thereby making detailed examination of some important structures impossible together with the interpretation of power Doppler signal sometimes unreliable. In addition, the deep location of the hip can confer further problems to US scanning in obese or particularly muscular subjects.

Ultrasound imaging for the rheumatologist IV. Ultrasonography of the knee.

Ultrasound examination of the knee is particularly useful in the detection of synovitis, early degenerative changes within the articular cartilage of the femoral condyles, calcifications within the articular cartilage layer and menisci, bursitis, and popliteal cysts. Also, important anatomical information about the structural integrity of the supporting tissues around the knee can be obtained by ultrasound in patients presenting with 'knee pain'. We review the available evidence about the use of ultrasound in knee examination, provide information on the technical equipment and scanning methods and discuss the still controversial issues.

Ultrasound imaging for the rheumatologist V. Ultrasonography of the ankle and foot.

Ultrasonography (US) is a useful tool for imaging, which can be used for the assessment of joints and periarticular structures in all rheumatological disorders. In patients with pain and/or swelling of the ankle and foot, US provides information about the presence of joint effusion, synovitis, tenosynovitis, tendinosis, and tendons tears, helping in the differential diagnosis between joint or tendon/enthesis involvement. Moreover, US allows clinicians to monitor and guide needle positioning to inject pharmaceutical substances more safely and effectively even in hard-to-reach sites. US represents an accurate, safe and low-cost technique that can be used for the examination of the ankle and foot in rheumatic disorders.

Ultrasound imaging for the rheumatologist. VI. Ultrasonography of the elbow, sacroiliac, parasternal, and temporomandibular joints.

Ultrasound (US) examination of the elbow and parasternal joints is very useful to detect synovitis, degenerative changes, intrarticular calcification or soft tissue abnormalities. More recently new fields of research involving the sacroiliac and temporomandibular (TM) joints have evolved. Moreover, important information has been obtained about vascularization of the synovial joint in the sacroiliac region and structural modification such as internal derangement in the TM joint.. In this paper, we review and discuss the role of US in the evaluation of elbow, sacroiliac, parasternal and TM joint pathology.

Treatment of rheumatoid arthritis: our experience.

Although an incredible amount of time, work and money has been spent in the evaluation of the relative efficacy of anti-rheumatic drugs, no specific resolutive therapy is currently available for rheumatoid arthritis. In these authors' experience early rheumatoid arthritis should be treated with the most powerful non-steroidal anti-inflammatory drug (indomethacin) and the most tolerated disease modifying anti-rheumatic drug (hydroxychloroquine) available. With respect to hydroxychloroquine, auranofin has a comparable efficacy, but the incidence of side effects is significantly higher than with hydroxychloroquine. Sulphasalazine provides very good results. The enthusiasm for this drug is moderated only by the high frequency of patient drop outs. Corticosteroids should be only used in patients with active disease who do not respond to conventional therapy, and/or those with life-threatening complications (i.e., vasculitis).
