Survey of arthroscopy performed by rheumatologists.

OBJECTIVE: To determine the international distribution and practice of arthroscopy performed by rheumatologists and to evaluate proposed guidelines on minimum standards for training in arthroscopy in the context of current clinical practice. METHODS: A questionnaire was sent to all rheumatology centres identified as practising arthroscopy, by (i) searching Medline from 1966 to 1999, (ii) searching the abstract books of the annual general meetings of ACR, BSR and EULAR from 1980 to 1999, and (iii) correspondence with all the centres identified. RESULTS: Thirty-six rheumatology centres were confirmed as performing arthroscopy (24 in Europe, 10 in USA and two in Australia) and 33 (92%) centres completed the questionnaire. Twenty-five (76%) of the 33 centres performing arthroscopy had started to perform it since 1990 and 72 rheumatologists are now trained in arthroscopy. A total of 16532 arthroscopies had been performed (median=220 arthroscopies/centre, range 20-5000); 50.5% of the arthroscopies had a primary clinical indication and 49.5% had a primary research indication. Most centres fulfilled the minimum standards for arthroscopic facilities and the proposed minimum standards in training were acceptable to 76% of respondents. Complication rates were calculated for 15682 arthroscopies where routine follow-up data were available [joint infection, 16 (0.1%); wound infection, 17 (0.1%); haemarthrosis, 141 (0.9%); deep venous thrombosis, 31 (0.2%); neurological damage, 3 (0.02%), thrombophlebitis, 12 (0.08%), other, 8 (0.06%)]. Irrigation volume correlated with wound infection rate (r=0.41, P=0.03) and centres performing cartilage biopsy had a higher rate of haemarthrosis (P=0.007). CONCLUSION: The last decade has seen rapid growth in arthroscopy performed by rheumatologists in an out-patient setting under local and regional anaesthesia. Proposed minimum standards for training in rheumatological arthroscopy reflect current practice accurately and are acceptable to the majority of arthroscopists. Complication rates of rheumatological arthroscopy are similar to those reported in the orthopaedic literature.

Matrix metalloproteinase 9, apoptosis, and vascular morphology in early arthritis.

OBJECTIVE: To examine matrix metalloproteinase 9 (MMP-9) in the synovial fluid (SF) and synovial membrane (SM) in relation to vascular endothelial cell (EC) apoptosis, vascular endothelial growth factor (VEGF), and SM vascular pattern. METHODS: Thirty-four patients underwent needle arthroscopy of the knee joint; 12 had early rheumatoid arthritis (RA), 12 had early psoriatic arthritis (PsA), and 10 had osteoarthritis (OA). The early RA and early PsA patients were matched for disease activity. SF levels of MMP-9 and VEGF were measured by an enzyme-linked immunosorbent assay, and EC apoptosis was measured by TUNEL assay. MMP-9 expression was examined in SM by immunohistochemistry. Synovial tissue explants were stimulated with VEGF, and MMP-9 levels were measured in the supernatants. The synovial vascular pattern was recorded. RESULTS: SF MMP-9 levels were significantly higher in early PsA patients than in early RA patients; OA patients had minimal levels. MMP-9 levels correlated with blood vessel morphology and SF VEGF levels. MMP-9 expression was greater in early PsA SM than in early RA SM, but the difference was not significant. In contrast however, EC apoptosis was greater in early RA SM than in early PsA SM. MMP-9 levels increased 2-fold and 9-fold, respectively, in SM explant culture supernatants on day 7 in response to stimulation with 25 ng/ml and 50 ng/ml of VEGF. CONCLUSION: SF MMP-9 levels correlate with the pattern of SM neovascularization and SF VEGF levels in early inflammatory arthritis, and VEGF increases MMP-9 production by SM. Endothelial cell apoptosis, however, appears to be more prevalent in early RA. This combination of factors may explain the pattern of differential angiogenesis in these arthritides.

Detection of Mycobacterium tuberculosis group organisms in human and mouse joint tissue by reverse transcriptase PCR: prevalence in diseased synovial tissue suggests lack of specific association with rheumatoid arthritis.

Infection with mycobacterial species, including Mycobacterium tuberculosis, has long been implicated in the etiopathology of rheumatoid arthritis (RA) on the basis of clinical and pathological similarities between tuberculosis and RA. Despite evidence of immune responses to mycobacterial antigens in RA patient synovial fluid, cross-reactivity between these and host joint antigens, and the presence of M. tuberculosis protein antigen in RA synovial fluid, a definite causal association with RA has not been shown. Previous studies from our laboratory using reverse transcriptase PCR (RT-PCR) of bacterial rRNAs have shown RA synovium to be colonized by a diverse range of bacteria, most of commensal origin. However, M. tuberculosis group organism (MTG) RNA sequences were found in one RA patient tissue. Since this was considered of sufficient interest to warrant further investigation, we devised a M. tuberculosis-specific nested RT-PCR test which could be used for detection of MTG in a mixed pool of bacterial crDNAs. This test was used to investigate the distribution of MTG in RA synovial tissue and also non-RA arthritis and healthy control tissues and was also used to examine the tissue distribution of MTG in an acute and chronic model of M. tuberculosis infection in the BALB/c mouse. MTG sequences were found in a high proportion of RA patient synovial tissues but also in non-RA arthritis control tissues at lower frequency. This likely reflects trafficking of persistent M. bovis BCG to inflamed joint tissue, irrespective of cause. MTG were not found in healthy synovial tissue or the tissue of patients with undifferentiated arthritis. In both the acute and chronic models of infection in BALB/c mice, M. tuberculosis was also found to have trafficked to joint tissues, however, no signs of inflammation, arthritis, or pathology associated with M. tuberculosis infection was seen. These combined results would argue against a specific causal role of MTG in RA-like arthritis; however, their role as adjuvant in immune dysfunction in an innately susceptible host cannot be excluded.

Opinions among mandated reporters toward child maltreatment reporting policies.

OBJECTIVE: This study investigates the opinions of social workers, pediatricians, and physician assistants in their support for the existing child maltreatment mandated reporting policy and an alternative reporting policy. Differences in professional training, age, gender, reporting behavior, attitudes towards reporting, and level of certainty needed to report were considered in determining which group of mandated reporters was most likely to support either the existing or an alternative policy. METHOD: A total of 382 social workers, pediatricians, and physician assistants in Connecticut and Massachusetts completed a self-report questionnaire. This sample represented an overall adjusted response rate of 76%. RESULTS: There was slightly more support for the existing reporting policy compared to the alternative policy. After controlling for age, attitudinal variables, and reporting behavior, social workers were significantly more likely to favor an alternative child maltreatment reporting policy than pediatricians or physician assistants. Also, those mandated reporters who had not consistently reported all suspected cases of maltreatment were significantly more likely to favor the alternative policy than consistent reporters. CONCLUSIONS: Because the majority of mandated reporters do not consistently report all suspected cases of maltreatment and support for an alternative reporting policy varies among different groups, consideration of alternative strategies and policies that address the concerns of different types of professionals may be appropriate.

Quantitative microscopic analysis of inflammation in rheumatoid arthritis synovial membrane samples selected at arthroscopy compared with samples obtained blindly by needle biopsy.

OBJECTIVE: To evaluate microscopic measures of inflammation in rheumatoid arthritis synovial tissue samples selected at arthroscopy compared with those obtained blindly by needle biopsy from the suprapatellar pouch (SPP) of the same joint. METHODS: Samples were selected at knee arthroscopy from the SPP and the lateral and medial gutters. Immediately following arthroscopy, a biopsy needle was inserted through the same portal into the SPP by a second investigator, and 3 further samples were obtained blindly. Using standard immunohistologic methods, all samples were analyzed by a single investigator without knowledge of the original tissue location and biopsy technique. Following staining with anti-CD3 and anti-CD68 monoclonal antibodies, T lymphocyte and macrophage infiltration were measured by quantitative analysis. RESULTS: Synovial tissues from 14 patients were analyzed. In comparing microscopic measures of inflammation using the 2 procedures, mean scores of lining cell depth and the percentage of CD68+ cells in the lining layer correlated positively (tau = 0.59, P = 0.003 and tau = 0.73, P = 0.0003, respectively). In the sublining layer, CD3+ cell counts also correlated significantly (tau = 0.71, P = 0.0004). Sublining CD68+ cell counts did not correlate. This was explained by the observation that CD68+ cell infiltration in areas adjacent to articular cartilage was significantly greater than in the SPP (P = 0.01), suggesting preferential trafficking to this site by macrophages, but not by T lymphocytes. Macroscopic appearance at arthroscopy did not predict microscopic features. CONCLUSION: Most microscopic measures of inflammation in synovial tissue samples obtained blindly from the SPP were similar to those determined in samples selected at arthroscopy. However, measurements in samples from the SPP may underestimate the intensity of macrophage infiltration in areas more adjacent to cartilage. These observations have important implications for future study of macrophage function in synovial tissue.

The acute phase and function in early rheumatoid arthritis. C-reactive protein levels correlate with functional outcome.

OBJECTIVE: To discover whether normalization of C-reactive protein (CRP) in patients with rheumatoid arthritis (RA) results in stabilization of their functional state, and whether a measure of disease activity can be used as a predictor of functional outcome. To examine the relationship between change of CRP and Health Assessment Questionnaire (HAQ) over a 24 mo period to define the sensitivity of HAQ to change. METHODS: A prospective study of 109 consecutive patients who fulfilled the American College of Rheumatology criteria for RA and had elevated CRP before steroid or 2nd line therapy. A full clinical assessment including HAQ was performed at presentation and at 3, 6, 12, and 24 mo. On the basis of the change in CRP at 6 mo, patients were divided into 3 groups: (1) CRP suppression to normal, (2) 50% reduction in CRP, and (3) less than 50% CRP change. RESULTS: The 3 groups were clinically and immunologically similar at onset. At 6 mo the median HAQ fell to 5 (lower to upper quartiles 7.5 to 19) in Group 1 (CRP normalized, n = 34), 6 (3.75 to 10) in Group 2 (CRP reduced by 50%, n = 30), and 12 (6 to 18) in Group 3 (less than 50% CRP change, n = 44), p < 0.005 for Groups 1 and 2 versus Group 3. At 12 and 24 mo HAQ remained significantly lower in Groups 1 and 2 compared with Group 3. In Group 1, patients either maintained a normal CRP (n = 28) or their CRP became elevated (n = 6). Only in those patients in whom a re-elevation of the CRP occurred was deterioration in HAQ subsequently seen. CONCLUSION: Suppression of elevated CRP in patients with active RA is associated with improvement in functional score, whereas persistent elevation of CRP is associated with functional deterioration. Once abnormal CRP is suppressed, no functional deterioration is likely to occur without re-elevation in CRP. Therefore, elevated CRP provides a convenient short term correlation with functional outcome and can be used as a guide for therapy. A HAQ score is a sensitive indicator of change in early disease.

Clinical associations of dual-energy X-ray absorptiometry measurement of hand bone mass in rheumatoid arthritis.

Hand bone mineral density (BMD) measurement by dual-energy X-ray absorptiometry (DXA) has potential as a marker of progression in early rheumatoid arthritis (RA). We examined a DXA methodology and studied in a cross-sectional manner 202 patients with RA. Hand BMD correlated inversely with age and was higher in males. Hand BMD correlated with lumbar and femoral sites. In females, BMD of the hand correlated positively with grip strength and negatively with disability. Those with higher C-reactive protein (CRP) had significantly lower hand BMD than those with normal CRP. In patients with a normal CRP, the hand BMD:lumbar BMD ratios were significantly higher in patients with longer disease duration. Hand BMD correlates with measures of disease activity, functional capacity and also with lumbar and femoral BMD. Hand bone loss occurs in early disease, in the absence of detectable systemic disease, and before lumbar BMD loss. It has the potential to be an outcome measure in early disease.

Special issues in the etiologies and treatments of sexual problems among gay men.

Some of the special circumstances and issues involved in both the causes and treatments of sexual problems among gay men are discussed. Reported frequencies of specific dysfunctions are discussed, and desire, arousal, and orgasmic phases are used to describe the special problems gay men have. These categories are also used to explore some of the probable contributing factors and specific treatment issues and suggestions that have been found useful. Since there is some indication that inhibited ejaculation is a somewhat frequent problem among gay men and has been more difficult than some dysfunctions to treat, emphasis has been placed on possible causes and treatments that have been helpful. A category of sexually inexperienced gay men is also discussed.

Causes and treatments of sexual desire discrepancies in male couples.

Multiple causes and treatments of sexual desire discrepancies in male couples are catagorized and discussed. Theoretical constructs and examples of such problems are extrapolated primarily from the existing literature on inhibited sexual desire and from clinical experience. Treatment suggestions are based on a well-established multi-level model and adapted to apply more directly to homosexual couples.

The association of selected "masculine" sex-role variables with length of relationship in gay male couples.

This study investigates the association of selected masculine sex-role characteristics with the fact that a gay male relationship is ongoing or the partners have separated. Sixty couples (30 ongoing, 30 recently separated) from a large urban area responded to a self-report battery that included measures of sex-role identification and questions on demographic data, self-disclosure to partner, degrees of cooperation, and sexual plurality. The subjects had been born in the United States, were Caucasian, and ranged in age from 21-37. To a statistically significant degree, separated respondents scored lower on cooperation than ongoing subjects and were more likely to be androgynous. No difference between the groups emerged on the variables of self-disclosure or the number of sexual experiences outside the primary relationship.
