Distal extremity swelling with pitting edema in psoriatic arthritis: a case-control study.

OBJECTIVE: To evaluate the frequency and the clinical characteristics of distal extremity swelling with pitting edema in patients with psoriatic arthritis (PsA). METHODS: This was a case-control study of consecutive outpatients with PsA (old and new diagnosis) observed over a 3-month period in three secondary referral centers in Italy. As controls we used the two consecutive rheumatic outpatients, excluding those with spondylarthropathies, observed after a PsA patient. The demographic and clinical features were assessed by clinical examination and review of the medical records. RESULTS: A total of 183 patients with PsA and 366 controls were evaluated. Distal extremity swelling with pitting edema was recorded in 39/183 (21%) PsA patients and in 18/366 (4.9%) controls (p < 0.0001). In 8/39 (20%) patients this feature presented as a first, isolated manifestation of PsA, and in 8 others it was associated with other features of PsA at diagnosis. The upper and lower extremities were affected, predominantly asymmetrically, in 40% and 60% of the cases respectively. In patients with pitting edema compared to those without this feature, the frequency of Achilles enthesitis and plantar fasciitis, calculated together, was higher (p < 0.05) and the duration of arthritis was significantly lower (p = 0.02). In 7 patients the clinical evidence of a predominant involvement of tenosynovial structures was confirmed by MRI. CONCLUSION: Upper or lower distal extremity swelling with pitting edema due to tenosynovitis, usually unilateral, is a common feature in PsA patients and may represent the first, isolated manifestation of the disease.

Flow cytometric and molecular analysis of proliferative activity and DNA content in neuroblastoma: presence of stationary cells in S-phase.

Twenty-nine previously untreated neuroblastomas were analyzed for DNA content and percentage of cells in S-phase, both determined by flow cytometry, and N-myc oncogene copy number. Twelve of them were also tested for histone H3 transcript levels as a marker of actual proliferative activity. A significantly higher S-phase fraction was associated with advanced stages of disease, unfavorable (i.e., near-diploid and near-tetraploid) DNA content, and N-myc amplification. The occurrence of six tumors with a remarkable (greater than or equal to 10%) S-phase fraction but lacking histone H3 transcripts suggests the presence of stationary S-phase cells in neuroblastoma.

Inflammatory changes of hip synovial structures in polymyalgia rheumatica.

OBJECTIVE: To investigate the hip inflammatory lesions and to evaluate the accuracy of clinical examination compared to magnetic resonance imaging (MRI) in patients with polymyalgia rheumatica (PMR) with pelvic girdle symptoms. Secondary end-point was to evaluate the sensitivity and specificity of ultrasonography (US) compared to MRI in the assessment of hip lesions. METHODS: Case-control study of 20 consecutive PMR patients and 40 controls with different rheumatic conditions. Both groups were clinically assessed for the presence of hip synovitis, trochanteric, iliopsoas and ischiogluteal bursitis. Hip MRI was performed in all case-patients and in 10 controls. Both groups were examined by US. An additional group of 10 healthy controls was examined by hip US. RESULTS: Both MRI and US detected trochanteric bursitis in 100% of PMR patients, bilateral in 18/20 (90%), and in 12/40 (30%) controls (p < 0.001). Hip synovitis was detected in 17/20 (85%) by MRI and in 9/20 (45%) by US (p < 0.02) in case-patients and in 18/40 (45%) controls. In PMR, MRI and US showed iliopsoas bursitis in 10/20 (50%) and 6/20 (30%) and ischiogluteal bursitis in 5/20 (25%) and 4/20 (20%) with no differences compared to controls. Clinical examination showed a good accuracy for hip synovitis, trochanteric and ischiogluteal bursitis, while it overestimated the presence of iliopsoas bursitis. US was less sensitive than MRI for the detection of hip synovitis and iliopsoas bursitis (53% and 60%). CONCLUSION: Trochanteric bursitis represents the most frequent hip lesion in PMR. A careful physical examination allows to detect all inflammatory lesions excluding iliopsoas bursitis. US is less sensitive than MRI in the assessment of hip synovitis and iliopsoas bursitis.

Tuberculous spondylitis as a cause of inflammatory spinal pain: a report of 4 cases.

Patients are said to have inflammatory spinal pain if they fulfill at presentation 4 of the following 5 criteria: duration of spinal discomfort for at least 3 months, spinal morning stiffness, age less than 40, insidious onset of symptoms, and no relief from pain with rest, but improvement with exercise. Inflammatory spinal pain is typical of the spondylarthropathies. Only in a minority of the cases it is found in other rheumatic disorders such as rheumatoid arthritis, fibromyalgia or infectious spondyilitis. Tuberculous spondylitis is rarely mentioned as a possible cause of inflammatory spinal pain. We describe 4 patients with tuberculous spondylitis seen over a 3-year period who met the clinical criteria for inflammatory spinal pain at presentation. We conclude that inflammatory spinal pain may be a presenting feature, albeit rare, of tuberculous spondylitis. Awareness of this finding should help facilitate the proper diagnosis and the institution of appropriate therapy.
