Chronic use of non-steroidal anti-inflammatory drugs does not alter colonic mucosa of patients without diarrhoea.

BACKGROUND: Several types of colitis can be NSAID-induced, but whether chronic use of NSAIDs alters colonic mucosa in patients without diarrhoea is not known. PATIENTS AND METHODS: Biopsy specimens of rectal mucosa were taken in six patients with rheumatoid arthritis without diarrhoea receiving NSAIDs (group 1, n=6). Patients with rheumatoid arthritis without diarrhoea not receiving NSAIDs (group 2, n=9), and patients undergoing surveillance colonoscopy (group 3, n=23) served as controls. In all patients from the three study groups, intraepithelial lymphocyte count and apoptotic cell count were assessed, and sub-epithelial collagen band thickness was measured. Leucocyte population of lamina propria was evaluated semi-quantitatively. HLA-DR and CD25 expression of mucosal cells was appreciated by immunohistochemistry. RESULTS: Intraepithelial lymphocyte count was in the normal range in all three group patients, and not statistically different between groups. Apoptotic epithelial cell count was not different between groups. Sub-epithelial collagen band thickness was normal in all the patients. No patient had a marked infiltration of lamina propria by leucocytes, and HLA-DR and CD25 were normally expressed in all patients. CONCLUSION: These results from a small sample of patients suggest that patients without diarrhoea receiving NSAIDs on a long-term basis do not develop microscopic or inflammatory colitis.

[Destructive arthritis of the hip in Crohn disease. 10 cases].

OBJECTIVES: Destructive arthritis of the hip joint is a rare manifestation of Crohn's disease. We evaluated its frequency and clinical features in comparison with spondylarthritis and assessed the clinical course. METHODS: One hundred patients with Crohn's disease were followed prospectively in search of destructive arthritis of the hip joint. Patients with both Crohn's disease and manifestations of inflammatory joint disease hospitalized in three rheumatology units were also evaluated retrospectively. RESULTS: The prevalence of destructive hip disease was 2% in patients with Crohn's disease. Ten patients had destructive arthritis of the hip. Three had ankylosing spondylitis, 5 had spondylarthritis not responding to the criteria of ankylosing spondylitis and 2 had no axial joint disease. In all patients, signs of hip joint disease were a narrowed intra-articular space, bone condensation, osteophytosis and features of joint destruction. Manifestations were similar to those in patients with hip joint disease related to idiopathic ankylosing spondylarthritis. The clinical course was poorly controlled by anti-inflammatory drugs or treatment of the inflammatory bowel disease. Synoviorthesis were required and were effective in most cases. Total hip replacement was required in 3 cases. CONCLUSION: Destructive arthritis of the hip in patients with Crohn's disease is a rare complication causing severe functional impairment further handicapping the patient with a chronic bowel disease.

[Segmental myocarditis in Churg-Strauss syndrome. Review of the literature apropos of a case].

We describe a 25-year old man in whom segmental myocarditis and pericarditis was diagnosed using two-dimensional echocardiography. Churg-Strauss syndrome was suspected in the presence of asthma and evidence of hypereosinophilia. Early therapy with oral prednisone led to resolution of pericarditis but septal hypokinesia was still present after 4 years. The pathophysiology of segmental myocarditis in the Churg Strauss syndrome is discussed.

[Present status of Poncet's tuberculous rheumatism. A new case].

A case of noninfectious polyarthritis of over one year's duration with calcaneal enthesopathy in a patient with visceral tuberculosis is reported. This pattern, termed Poncet's disease, shares pathophysiologic mechanisms with Freund's complete adjuvant-induced arthritis. Future studies should include polymerase chain reaction studies to look for the tubercle bacillus in joint fluid or synovial biopsy specimens.

[Polyepiphyseal dysplasias and chondrodysplastic rheumatism].

The hip is the commonest site of polyepiphyseal dysplasia. These genotypic diseases are characterised by the presence of a moderate dysmorphic syndrome associated with developmental anomalies of the epiphyses. Metaphyseal and spinal alterations are absent or minor. The joint symptoms associated with these diseases have a polymorphic clinical and radiological expression. Osteoarthritis, the commonest manifestation, has several specific signs which distinguish it from "common" osteoarthritis: early onset, severity, dissemination and involvement of non-weight-bearing joints. Osteochondromatous formations, related to fragmentation of the epiphyses, are present in approximately one third of patients and may sometimes be responsible for joint locking. Progressive tendon retraction of the extremities has been exceptionally reported. Recurrent acute arthritis is more frequent, affecting joints with a radiological appearance often similar to that of metabolic joint disease with subchondral bone changes and occasionally calcified margins.

Case report 728: Desmoplastic fibroma.

A 69-year-old woman with a 25-year history of recurrent sciatica presented with an expanding lytic lesion of the right side of the first sacral vertebra. Histological examination proved the lesion to be a DF. DF is usually diagnosed in young patients and is very rarely located in the spine and sacrum. The growth rate of the tumor was presumed to be very low because it had not progressed from radiological studies performed 9 years previously. The clinical, radiological, and pathological features of DF are described, and the differential diagnoses are discussed. The most difficult problem is to distinguish DF from a low-grade fibrosarcoma or chordoma.

[Magnetic resonance imaging of fluorosis and stress fractures due to fluoride].

Osteocondensation of the spine and stress fractures of the appendicular bones are observed under treatment with sodium fluoride or after long-term drinking of Vichy Saint-Yorre spring water. Five patients with a mean total dose of fluoride intake of 24.7 g (9-66) were studied with MR imaging. Two of them had a diffuse osteocondensation; MRI showed a low signal intensity in the vertebrae on T1 and T2-weighted images. MRI was performed in an asymptomatic patient who was being treated with sodium fluoride for 16 months; it revealed a heterogenous low signal intensity in the pelvis and femoral metaphysis. Two patients experienced stress fractures; MRI demonstrated a linear area of very low signal intensity surrounded by an area of decreased signal intensity on T1-weighted images and high signal intensity on T2-weighted images. MRI of fluorosis shows a non specific low signal intensity linked to a densifying image on the standard radiograph or an area of high technetium-99m intake on bone scan.
