RESUMO

OBJECTIVE: To compare the interobserver reliability of three-dimensional (3D) volumetric ultrasonography (US) and 2D real-time US in detecting inflammatory and destructive changes in rheumatoid arthritis (RA) wrist and hand. METHODS: Two RA patients were selected by a rheumatologist who performed independently a grey-scale and power Doppler (PD) volumetric acquisition at three anatomic sites in their more symptomatic wrist/hand using two identical scanners equipped with 3D volumetric probe. Twelve rheumatologists expert in MSUS were randomly assigned to a US scanner and a patient. In the first part of the study, each group of experts blindly, independently, and consecutively performed a 2D real-time grey-scale and PD US investigation of inflammatory changes and/or bone erosions at the three anatomic sites. In the second part of the study, each group of investigators blindly evaluated the same pathologic changes in the 6 volumes from the patient not scanned by them. RESULTS: The kappa values were higher for 3D volumetric US than for 2D US in the detection of synovitis/tenosyno-vitis (0.41 vs. 0.37) and PD signal (0.82 vs 0.45) and in the PD signal grading (0.81 vs. 0.55). CONCLUSION: 3D volumetric US may improve the interobserver reliability in RA multicentre studies.

RESUMO

OBJECTIVE: To develop education guidelines for the conduct of future European League Against Rheumatism (EULAR) musculoskeletal ultrasound (MSUS) courses. METHODS: We undertook a consensus-based, iterative process using two consecutive questionnaires sent to 29 senior ultrasonographer rheumatologists who comprised the faculty of the 14th EULAR ultrasound course (June 2007). The first questionnaire encompassed the following issues: type of MSUS educational model; course timing; course curriculum; course duration; number of participants per teacher in practical sessions; time spent on hands-on sessions; and the requirements and/or restrictions for attendance at the courses. The second questionnaire consisted of questions related to areas where consensus had not been achieved in the first questionnaire, and to the topics and pathologies to be assigned to different educational levels. RESULTS: The response rate was 82.7% from the first questionnaire and 87.5% from the second questionnaire. The respondents were from 11 European countries. The group consensus on guidelines and curriculum was for a three-level education model (basic, intermediate and advanced) with timing and location related to the annual EULAR Congresses. The topics and pathologies to be included in each course were agreed. The course duration will be 20 h. There will be a maximum of six participants per teacher and 50-60% of total time will be spent on practical sessions. There was also agreement on prerequisite experience before attending the intermediate and advanced courses. CONCLUSION: We have developed European agreed guidelines for the content and conduct of EULAR ultrasound courses, which may also be recommended to national and local MSUS training programmes.

RESUMO

OBJECTIVE: To assess the interobserver reliability of the main periarticular and intra-articular ultrasonographic pathologies and to establish the principal disagreements on scanning technique and diagnostic criteria between a group of experts in musculoskeletal ultrasonography. METHODS: The shoulder, wrist/hand, ankle/foot, or knee of 24 patients with rheumatic diseases were evaluated by 23 musculoskeletal ultrasound experts from different European countries randomly assigned to six groups. The participants did not reach consensus on scanning method or diagnostic criteria before the investigation. They were unaware of the patients' clinical and imaging data. The experts from each group undertook a blinded ultrasound examination of the four anatomical regions. The ultrasound investigation included the presence/absence of joint effusion/synovitis, bony cortex abnormalities, tenosynovitis, tendon lesions, bursitis, and power Doppler signal. Afterwards they compared the ultrasound findings and re-examined the patients together while discussing their results. RESULTS: Overall agreements were 91% for joint effusion/synovitis and tendon lesions, 87% for cortical abnormalities, 84% for tenosynovitis, 83.5% for bursitis, and 83% for power Doppler signal; kappa values were good for the wrist/hand and knee (0.61 and 0.60) and fair for the shoulder and ankle/foot (0.50 and 0.54). The principal differences in scanning method and diagnostic criteria between experts were related to dynamic examination, definition of tendon lesions, and pathological v physiological fluid within joints, tendon sheaths, and bursae. CONCLUSIONS: Musculoskeletal ultrasound has a moderate to good interobserver reliability. Further consensus on standardisation of scanning technique and diagnostic criteria is necessary to improve musculoskeletal ultrasonography reproducibility.

RESUMO

OBJECTIVE: To evaluate the clinical response and safety profile of infliximab in refractory ankylosing spondylitis patients. METHODS: Patients with active ankylosing spondylitis, despite methotrexate therapy, were included in an open-label, single-centre study. Patients were given 3-5 mg/kg infliximab infusions at Weeks 0, 2, 6, and q8 etc up to Week 30, together with methotrexate at the dosage taken prior to study inclusion, and were followed-up for a 34-week period. RESULTS: Nine patients with mean age 43 years and mean disease duration 7 years, diagnosed with pure axial ankylosing spondylitis were included. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), duration of morning stiffness, physician's global assessment of disease activity (PhGADA), visual analogue scale (VAS) pain, enthesis index, occiput-to-wall test, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and Bath Ankylosing Spondylitis Functional Index (BASFI) significantly improved by Week 6. No adverse events related with the drug were recorded during the 34-week follow-up period. CONCLUSION: Efficacy results are similar to those previously published. No adverse events were seen during therapy, and antinuclear antibody profiles were negative. The association of methotrexate with infliximab can improve the safety profile.

RESUMO

BACKGROUND: High frequency ultrasonography is an accurate non-invasive imaging technique for evaluating patients with painful shoulder. OBJECTIVE: To compare the clinical diagnosis established by a physical examination with high frequency ultrasonographic findings in patients with painful shoulder. METHODS: Thirty one consecutive patients with a first flare of shoulder pain were prospectively included in the study. All had a physical examination performed by two blinded rheumatologists. Ultrasonographic examination was carried out within one week of the physical examination by a third rheumatologist experienced in this technique who had no knowledge of the clinical findings. Ultrasonography was considered the optimal diagnostic technique. RESULTS: Clinical assessment showed low accuracy in the diagnosis of periarticular shoulder lesions. CONCLUSION: Ultrasonography should be used wherever possible to improve diagnosis and treatment of painful shoulder.

RESUMO

We studied the ultrasonographic (US) features of the pes anserinus insersion (PA) and subcutaneous medial knee fat in patients clinically diagnosed of pes anserinus tendino-bursitis (PATB) syndrome. Thirty seven consecutive patients with suspected PATB were clinically evaluated and their knees examined using a 7.5 MHz linear probe. In twenty-three patients with unilateral clinical PATB (group A) the painful knee was compared with their painless opposite knee. Six patients with bilateral clinical PATB (group B) were compared with 6 healthy controls (group C). All patients were women with radiographic knee osteoarthritis in 93% and body mass index > 27 in 75%. US pes anserinus tendinitis was found in one symptomatic knee and pes anserinus bursitis in two symptomatic knees and in one asymptomatic knee. No US signs of panniculitis were found in patients and controls. In conclusion, patients diagnosed of PATB syndrome in rheumatology rarely have US tendinitis or bursitis of the PA.

RESUMO

The recent improvement of musculoskeletal imaging achieved by high-frequency ultrasonography (US) and its important advantages as a routine dynamic imaging tool-providing results rapidly, absence of secondary effects, and low cost-make US a very useful tool in rheumatologic practice. We prospectively compared high-frequency US with magnetic resonance imaging (MRI) in patients with painful shoulder syndrome.Thirty-four consecutive patients (36 shoulders) with a first flare of shoulder pain were included in the study. US and MRI shoulder examination were performed within 2 weeks. US shoulder examinations were performed by a rheumatologist experienced in US, without knowledge of the MRI results. The MRI results were considered the gold standard. US showed high sensitivity, specificity, and positive and negative predictive values (range 85.7%-100%) in the diagnosis of tendinitis, partial-thickness, and full-thickness tear of the rotator cuff and degenerative changes of the acromio-clavicular joint. Rotator cuff calcifications were detected only by US. We highly recommend that for many painful shoulders, appropriately trained rheumatologists can perform US examinations to establish an accurate diagnosis and, thereby, improve therapy.

RESUMO

The in vitro and in vivo tolerance of sertaconazole gel, a new topical azole antifungal, was studied. Ketoconazole gel (Panfungol) was used as a reference substance. The methods applied for tolerance assessment were the bovine corneal opacity and permeability test for the in vitro assay and a modified Draize test for the in vivo assay. The results obtained show that both substances can be classified as slightly irritant and with acceptable tolerance. However, unlike ketoconazole gel, sertaconazole gel did not cause a positive lesion index in vivo. Ketoconazole was 5.25 times more irritant in vitro than sertaconazole gel, whose effect was similar to that of saline solution. Consequently, the negligible irritant effect of sertaconazole gel on a type of epithelium that is extremely sensitive, i.e. the cornea, confirms the good tolerance of this new antifungal gel on other structures such as the skin and mucous membranes.
