RESUMO

In a prospective randomised study 31 patients were allocated to either arthrodesis or Mayo resection of the first metatarsophalangeal joint as part of a total reconstruction of the rheumatoid forefoot. Of these, 29 were re-examined after a mean of 72 months (57 to 80), the Foot Function Index was scored and any deformity measured. Load distribution was analysed using a Fscan mat in 14 cases, and time and distance were measured in 12 of these patients using a 3D Motion system. We found excellent patient satisfaction and a significant, lasting reduction of the Foot Function Index, with no statistically significant differences between the groups. There were no significant differences in recurrence of the deformity, the need for special shoes, gait velocity, step length, plantar moment, mean pressure or the position of the centre of force under the forefoot. The cadence was higher and the stance phase shorter in the fusion group. These results suggest that a Mayo resection may be an equally good option for managing the first metatarsophalangeal joint in reconstruction of the rheumatoid forefoot.

RESUMO

We found that 23% of 435 patients treated for a femoral neck fracture in our department also were treated for a urinary tract infection during their hospital stay. The most common pathogen was Escherichia coli, sensitive for mecillinam in 98% of the cases. The most frequently used antimicrobial agent was a broad-spectrum antibiotic, fluoroquinolon, although the most reasonable choice would have been a non broad-spectrum agent such as mecillinam. Catheterization was not a predisposing factor for urinary tract infection, but a poor medical condition and female sex were. We did not find a higher mortality rate among patients with a urinary tract infection.

RESUMO

OBJECTIVES: To define synovial apoptosis with respect to disease duration, inflammatory cell type, FLIP (FLICE-like inhibitory protein), and cytokines expression in patients with rheumatoid arthritis (RA). METHODS: Synovial biopsy specimens from 11 patients with longstanding RA (median disease duration 21 years) and eight with early RA (median disease duration five months) were investigated. Apoptosis (TUNEL method combined with morphological analysis), cell surface markers (CD3, CD68), cytokines (interleukin (IL) 1alpha, IL1beta, tumour necrosis factor alpha, and IL6), and FLIP expression were evaluated. Computer assisted image analysis was used for quantification. RESULTS: The apoptosis level in RA synovium was significantly higher in the group of patients with longstanding RA than in the patients with early RA (8.8% v 0.6%, p=0.001), while the number of macrophages and FLIP expression were higher in the group with early disease than in the group with longstanding RA (16.2% v 8.3%, p=0.02 and 31.1% v 0.2%, p=0.001 respectively). All three markers correlated significantly with disease duration (R=-0.7, p<0.001 for FLIP, R=0.6, p=0.001 for apoptosis, and R=-0.5, p<0.05 for CD68). Cytokine expression and T cell score were not significantly different in early RA from longstanding RA. No differences were seen between patients treated or not treated with corticosteroids or between patients treated or not treated with disease modifying antirheumatic drugs. CONCLUSIONS: The findings suggest that RA synovial macrophages are resistant to apoptosis in early RA and express high levels of FLIP. During natural or drug modified disease progression the apoptotic mechanism may be restored with a specific increase of synovial apoptosis in patients with longstanding arthritis.

RESUMO

Four hundred and thirty-seven patients with femoral neck fractures were studied to determine the value of serum albumin estimations on admission. Serum albumin is a good predictor of mortality, and patients with low levels should be given additional nutritional support. We found that the serum albumin level is not useful in predicting deep wound infection. The infection rate of 3% does not justify the use of antibiotic prophylaxis in general.

RESUMO

OBJECTIVES: Assessment of the numbers and spatial distribution of cells producing interleukin 1alpha (IL1alpha), interleukin 1beta (IL1beta), tumour necrosis factor alpha (TNFalpha), and interleukin 6 (IL6) in the synovial membranes of patients with rheumatoid arthritis (RA). METHODS: Synovial tissue specimens from 40 patients with RA and eight patients with non-rheumatic disease were obtained by arthroscopy guided biopsy techniques or during joint surgery. A modified immunohistochemical method detecting cytokine producing rather than cytokine binding cells was applied to determine cytokine synthesis in fixed cryopreserved sections. Computerised image analysis methods provided comparative quantitative assessments. RESULTS: A wide variation between subjects was recorded for both quantities and profiles of expressed cytokines, despite similar macroscopic and histopathological features of inflammation. IL1alpha and IL1beta were the most abundant monokines identified, though produced at different sites. IL1alpha was predominantly seen in vascular endothelial cells, whereas IL1beta staining was mainly shown in macrophages and fibroblasts. Concordant results for the detection of TNFalpha at protein and mRNA levels were obtained with an unexpectedly low number of TNFalpha producing cells compared with IL1 expressing cells in many patients with RA. Specimens acquired arthroscopically from areas with maximum signs of macroscopic inflammation showed an increased number of TNFalpha producing cells in pannus tissue compared with that occurring in synovial villi of a given joint. This clustered distribution was not found for cells expressing any of the other studied cytokines. CONCLUSION: The recorded heterogeneous profile of proinflammatory cytokine synthesis in the synovial membrane among patients with RA may provide a clue for an understanding of the wide variation in responsiveness to different modes of antirheumatic treatment between patients.
