Background and Objective Lobular panniculitis, together with polyarthritis and intraosseous fat necrosis, may occasionally complicate pancreatic disease. This triad is known in the literature as the ...pancreatitis, panniculitis, and polyarthritis (PPP syndrome). We describe a case of the PPP syndrome and review the available literature to summarize the clinical characteristics of patients with this condition. Methods A patient with the PPP syndrome, with evidence of extensive intraosseous fat necrosis in the joints involved revealed by magnetic resonance imaging, is described and the relevant literature based on a PubMed search from 1970 to February 2008 is reviewed. The keywords used were pancreatitis or pancreatic disease, panniculitis, arthritis, and intraosseous fat necrosis. Results Including our case, 25 well-documented patients with the PPP syndrome have been reported. Our patient had few abdominal symptoms despite high serum levels of pancreatic enzymes. In our review of the literature, almost 2/3 of patients had absent or mild abdominal symptoms, leading to misdiagnosis. The delay in diagnosis and specific treatment of the underlying pancreatitis worsens the prognosis of this condition, which has a mortality rate as high as 24%. In nearly 45% of the patients, the arthritis follows a chronic course with a poor response to nonsteroidal anti-inflammatory drugs and corticosteroids, and the rapid development of radiographic joint damage. Conclusion Certain forms of pancreatic disease can very occasionally cause arthritis and panniculitis. Although uncommon, physicians should be alert to the possible presence of this syndrome for 2 reasons: first, unrecognized pancreatic disease can be fatal if not treated promptly; second, to avoid inappropriate and risky therapy to improve joint symptoms.
Objective To investigate whether rheumatoid arthritis (RA) and psoriatic arthritis (PsA) can be differentiated in the early stages of the disease (duration of symptoms ≤1 year) on the basis of ...magnetic resonance imaging (MRI) features of the hand and wrist. Material and methods Twenty early RA and 17 early PsA patients with symptomatic involvement of the wrist and hand joints and inconclusive radiographic studies were examined prospectively with contrast-enhanced MRI. Images were evaluated in accordance with the Outcome Measures in Rheumatology Clinical Trials recommendations. Results Certain MRI features, such as the presence of enthesitis or extensive diaphyseal bone marrow edema, were observed exclusively in PsA ( P = 0.0001). These distinctive findings were present in nearly 71% (12/17) of PsA patients. Diffuse and, in some cases, pronounced soft-tissue edema spreading to the subcutis was also seen more frequently in patients with PsA ( P = 0.002). There were no significant differences in the frequency of synovitis, bone erosions, subchondral bone edema, or tenosynovitis between the 2 groups. However, in RA extensor tendons were involved more often than the flexor tendons, whereas in PsA the opposite was observed ( P = 0.014). With respect to the discriminatory power of the different MRI findings examined, only the presence of enthesitis or diaphyseal bone edema and, to a lesser extent, the pattern of hand tendon involvement and the presence of soft-tissue edema accurately differentiated PsA from RA (all these features achieved accuracies greater than 0.70). Conclusions We observed significant differences in the MRI findings of the hand and wrist that can help to distinguish between RA and PsA in the early stages of disease. This imaging method could help to assist in the differential diagnostic process in selected patients in whom diagnosis cannot be unequivocally established after conventional clinical, biochemical, and radiographic examinations.
Abstract Objective To determine clinical and sonographic biomarkers predicting structural damage progression at 12 months of follow-up as measured by magnetic resonance imaging (MRI) in rheumatoid ...arthritis (RA) patients in clinical remission. Patients and methods We included patients with RA in clinical remission, defined as 28-joint disease activity score (DAS28)-erythrocyte sedimentation rate (ESR) <2.6 for >6 months. Ultrasound scans of both hands and knees and MRI of the dominant hand were performed at baseline and at 12 months. Results Out of 55 patients, 42 completed the follow-up. Among them, 78% were female, aged (median) 54 years; disease duration was 93 months. In total, 12 (28%) patients were taking oral prednisone, 34 (81%) conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), and 20 (47%) biological therapies. At baseline, 45% fulfilled criteria previously defined for ultrasound-defined active synovitis (UdAS) PD (power Doppler) signal + synovial hyperplasia ≥2. Multivariate analysis showed significant associations between baseline MRI erosion score, body mass index (BMI), disease duration, prednisone treatment, absence of biologic and csDMARDs, UdAS, and MRI erosion score progression after 12 months. In an exploratory analysis, serum levels of calprotectin correlated significantly with bone edema progression. Conclusions We identified clinical and sonographic markers of structural damage progression after 12 months follow-up in patients with RA in clinical remission. Meeting the criteria of ultrasound active synovitis, defined as simultaneous relevant synovial hyperplasia and PD, was associated with erosion progression after 12 months. Calprotectin was associated with bone edema, in an exploratory analysis.
Objective The diagnosis of rheumatoid arthritis (RA) is sometimes difficult to establish early in the disease process, particularly in the absence of its classic hallmarks. Our aim was to compare the ...practical usefulness of magnetic resonance imaging (MRI) of the hand versus anticyclic citrullinated peptide (anti-CCP) antibody testing to confirm the diagnosis of clinically suspected RA in the absence of rheumatoid factor (RF) and radiographic erosions. Methods We prospectively included patients with early inflammatory arthritis and strong clinical suspicion of RA, in whom initial complementary tests (RF and radiographs of hands, wrists, and feet) did not provide unequivocal confirmation of the diagnosis. In all patients, anti-CCP antibodies were assessed and contrast-enhanced MRI of the most affected hand was performed according to a specifically designed protocol. The MRI criterion for the diagnosis of RA was either the presence of synovitis with bone erosions or bone marrow edema, which is currently considered to be a forerunner of erosions. Results In the 40 patients (28 women), the mean age at diagnosis was 54 ± 6 years and the median duration of symptoms was 4 ± 2.6 months (range 1.5 to 12). Final diagnoses at 1-year follow-up were RA in 31 patients, undifferentiated arthritis in 7 (5 self-limiting), and psoriatic arthropathy (PsA) and antisynthetase syndrome in 1 patient each. Anti-CCP antibodies were positive only in 7 patients, all of whom were finally diagnosed with RA. The prevalence of anti-CCP positivity in our series of seronegative RA patients was thus 23% (7/31); in these patients the anti-CCP antibodies had a specificity of 100% (95% CI: 71.7 to 100) and sensitivity of 23% (95% CI: 9.6 to 41.1). Use of the MRI criterion led to the correct diagnosis in 100% of patients with RA and to false-positive results (1 with PsA and 1 with antisynthetase syndrome). The MRI criterion had a specificity of 78% (95% CI: 40.0 to 97.2) and sensitivity of 100% (95% CI: 90.8 to 100) for identification of seronegative RA. Conclusion Although the tests are not mutually exclusive, in our experience MRI is more helpful than anti-CCP antibody determination in confirming the diagnosis of clinically suspected early RA in patients in whom the diagnosis cannot be confirmed using conventional methods.
Abstract Objective To investigate the frequency, location, characteristics, and clinical significance of subaxial involvement (below C1–C2) in a series of patients with rheumatoid arthritis (RA) and ...symptomatic involvement of the cervical spine. Methods A total of 41 patients with RA were examined via cervical spine magnetic resonance imaging (MRI). A comparative analysis of the incidence of the different types of subaxial lesions was performed between these patients and 41 age- and sex-matched patients with symptomatic cervical spondylosis. Results Stenosis of the spinal canal was found at the subaxial level in 85% of RA patients, and at the atlantoaxial level in 44%. Comparative analysis between these patients and the cervical spondylosis patients revealed significant differences in the types and frequencies of subaxial lesions. For both conditions, signs of discopathy and end-plate osteophytosis were the most common abnormalities observed on magnetic resonance imaging (MRI). However, in the RA patients these abnormalities coincided with subchondral bone and ligamentous acute inflammatory changes and with secondary destruction (vertebral instability) or repair (vertebral ankyloses). Only evidence of subaxial myelopathy was significantly associated with an increased risk of neurological dysfunction among the RA patients Ranawat class II or III; P = 0.01; odds ratio (OR) = 11.43, although subaxial cord compression tended toward a significant association with the risk of neurological dysfunction ( P = 0.06; OR = 3.95). Conclusion Subaxial stenosis seems to be the consequence of both the inflammatory process and mechanical-degenerative changes. Despite its frequency, it was not usually related to the occurrence of myelopathy symptoms, not even in cases with MRI evidence of spinal cord compression.
Objective To investigate the frequency and clinical significance of bone marrow edema (BME) in a series of patients with rheumatoid arthritis (RA) and symptomatic involvement of the cervical spine. ...Methods We studied 19 consecutive RA patients with cervical spine magnetic resonance imaging (MRI) according to a specifically designed protocol that included short inversion time inversion recovery sequences. All cases had neck pain unresponsive to conventional treatment, neurological symptoms, or signs suggestive of cervical myelopathy, or cervical pain with evidence of atlantoaxial subluxation on radiographs. Results The mean age of the 19 patients (15 women and 4 men) at time of the study was 59 ± 12 years (range, 23-82) and the median disease duration was 14 ± 7.4 years (range, 4-30). BME was observed in 74% (14/19) of the patients: at the atlantoaxial level alone in 16% of the patients; subaxially alone in 16%; and at both levels in 42% of the patients. At the atlantoaxial level, BME was usually observed involving the odontoid process, whereas subaxially BME was limited to the vertebral plates and the interapophyseal joints. Patients with BME had higher erythrocyte sedimentation rate (ESR) values at the time of MRI examination ( P = 0.014) and more severe atlantoaxial joint MRI synovitis scores ( P = 0.05) compared with the remaining patients; the frequency of odontoid erosions was also greater in this group, but the difference did not reach statistical significance. Altogether, these data suggest a more severe inflammatory response in these patients. In this group a significant correlation was found between BME scores at atlantoaxial level and (1) ESR values ( r = 0.854; P = 0.001) and (2) atlantoaxial joint MRI synovitis scores ( r = 0.691; P = 0.001). Conclusion BME is frequently observed in patients with established RA and symptomatic cervical spine involvement. Both atlantoaxial and subaxial levels are equally affected. The presence of BME seems related to the intensity of the inflammatory response and to the severity of the atlantoaxial joint synovitis.
Abstract Puncture of trigger points in myofascial syndrome can be performed with greater safety for the patient under ultrasound-guided techniques. The identification of potentially hazardous ...structures in the path of the needle, together with the development and validation of tools like sonoelastography, spontaneous muscle contraction (twitch response), or vascular dynamics, helps us to be more accurate, specially in cases where the trigger points are in deep fasciae or muscular layers. Ultrasound-guided interfascial block, a known regional anesthetic technique, is emerging as a promising approach with minimum traumatic damage to the muscles.
