Hughes-Stovin syndrome (HSS) is a rare clinical disorder, which has been described as the presence of pulmonary artery aneurysm in the setting of systemic thrombosis. The term "Incomplete Behcet's Disease" has also been used to describe this syndrome due to the clinical and histopathological similarities between Behcet's disease and HSS. Indeed, pulmonary involvement can be indistinguishable between these two conditions of unknown pathophysiology. We describe an HSS patient who presented with a recurrent pulmonary artery aneurysm, review the clinical and pathological manifestations of HSS, discuss its similarities to Behcet's disease, and finally make the argument that HSS is in fact Behcet's disease.

OBJECTIVE: To determine what monitoring protocols rheumatologists use to identify adverse events in rheumatoid arthritis (RA) patients treated with methotrexate (methotrexate), etanercept (etanercept), infliximab (infliximab), and anakinra (anakinra), how often rheumatologists encounter treatment-altering adverse events in their RA patients receiving these treatments, and how they feel about and comply with the current monitoring guidelines. METHODS: Three hundred ten physician members of the American College of Rheumatology (ACR) were notified by e-mail of a survey that was posted on our rheumatology Web site. Questions were closed-ended and multiple choice in format. RESULTS: One hundred twenty-three responses were received (40%). Most rheumatologists reported that they utilize the ACR recommended screening tests at baseline before methotrexate treatment is initiated. Seventy-nine percent reported that treatment-altering abnormalities had occurred in <5% of their methotrexate-treated RA patients, and 88% reported that such abnormalities had occurred in <10% of such patients, in the previous 3 years. Forty-one percent believed liver function monitoring guidelines need to be changed; 59% said they would agree with new guidelines that would include a recommendation for liver function monitoring every 3-4 months. Most rheumatologists were not aware of any guidelines for monitoring by blood tests in RA patients treated with biologic agents, yet the majority reported that they order blood tests before patients start these therapies and on followup. CONCLUSION: Our survey indicates that treatment-altering liver function abnormalities in methotrexate-treated RA patients are rare, and more than half of rheumatologists agree that a less stringent monitoring regimen should be considered. Rheumatologists and pharmaceutical companies might work together to develop guidelines for monitoring of patients treated with biologic agents

The two major advances over the 1990s in the treatment of rheumatoid arthritis (RA) were a shift in strategy from a 'pyramid', in which disease modifying anti-rheumatic drugs (DMARDs) were deferred for several years, to the early aggressive use of DMARDs and widespread acceptance of methotrexate as the DMARD with the most long-term effectiveness and safety. Methotrexate courses are continued far longer than those of any other DMARD, an excellent indicator of greater effectiveness and safety. In one recent series, methotrexate was the first DMARD used in more than 80% of patients with RA. Studies which document the superiority of combinations of methotrexate with biological agents to methotrexate monotherapy select for only a minority of contemporary patients with RA who have severe disease activity and incomplete responses to methotrexate. In one locale, only 5% of patients met criteria for the Anti-Tumor Necrosis Factor Trial in RA with Concomitant Therapy (ATTRACT) trial and only 30% met the criteria for the Early Rheumatoid Arthritis (ERA) trial. In studies comparing methotrexate directly with biological agents, the biological agents have greater efficacy in patients with very severe disease, but the best results are seen in patients who take a combination of methotrexate and biologic agents. These data establish that methotrexate is the anchor drug and probably should be the first DMARD used in the majority of patients with RA at this time

Several databases of patients with early rheumatoid arthritis (RA) have been established in the USA. The University of Tennessee at Memphis Cohort was organized in 1967-1971 to enroll 50 young adults (16-44 years) with symptom onset of < or = 6 months who met the 1958 American Rheumatism Association (ARA) criteria for at least probable RA. Two important observations from this database were that many patients seen within the first 6 months of meeting the criteria for probable RA have a self-limited rather than progressive disease, and that progressive disease is predicted by a high number of baseline swollen and tender joints. The National Institutes of Health (NIH) cohort of patients with peripheral synovitis for > or = 6 weeks but < 12 months in at least one peripheral joint was established in 1994. At the one-year follow-up, 45% of the patients met the RA criteria, 9% had reactive arthritis, 6% had psoriatic arthritis, 5% had other rheumatic diseases, and 35% had undifferentiated arthritis. The number of active joints, rather than meeting the criteria for RA, was the primary determinant of function and performance after one year. The Western Consortium of Practicing Rheumatologists (CPR) was established in 1993 to enroll patients with an RA duration < 1 year, positive rheumatoid factor, > or = 6 swollen and > or = 9 tender joints, and no previous treatment with disease modifying anti-rheumatic drugs (DMARDs). Data from this cohort indicated the validity of self-report joint counts. American College of Rheumatology 20% improvement (ACR20) responses were seen in 50% of patients at 6 months and in 57% of patients at 24 months, while antinuclear antibodies (ANA) were seen in 69% of patients prior to the availability of biologic agents. The North American Cohort of Patients with Early RA (SONORA), which included patients with symptoms for > 3 but < 12 months, indicated that methotrexate (MTX) was the most frequently prescribed DMARD, being taken by more than half the patients. The Consortium for the Longitudinal Evaluation of African-Americans with RA (CLEAR) registry and DNA repository has enrolled 123 African-American patients with early RA of less than 2 years' duration to analyze genetic and non-genetic factors associated with disease severity. The Early RA Treatment Evaluation Registry (ERATER) of patients with early RA (< 3 years) was established in 2001. In this registry, MTX was the first DMARD used in 83% of patients, and most patients would not meet the criteria for inclusion in recent clinical trials of biological agents. Further observation of recent cohorts of patients with early RA over the next decade should be informative regarding whether aggressive intervention strategies and new DMARDs and biologic agents lead to improved long-term outcomes

Pregnancy outcomes among patients who underwent total hip arthroplasty (THA) during their reproductive years were retrospectively evaluated. Twenty-one patients reported pregnancies after THA and 20 had live births. No prosthesis-related problems were reported. This is the first study that provides a patient-based assessment of pregnancy outcomes and delivery in women who underwent THA. The preliminary data suggest THA had no adverse effect on subsequent childbearing

The hallmark of the inflammatory myopathies is muscle weakness. Although this feature can lead to significant disability and impairment of activities of daily living, its initial presentation may not be recognized early. Older individuals, in particular, may feel that the changes caused by myositis reflect the effects of aging rather than those of a disease process, and diagnosis, therefore, may be delayed. This factor has negative impact on the response to therapy. Inclusion body myositis, with its insidious onset in older people, and laboratory findings which may not be markedly abnormal, presents a diagnostic challenge. DM, with its characteristic symptomatic rash, is generally brought to medical attention more quickly. Another area of diagnostic concern occurs when associated organ involvement precedes myopathy. This has been observed, for example, with interstitial lung disease, and again represents a challenge to physicians. In this connection, the antisynthetase syndrome presenting with fevers, Raynaud's features, arthritis, or pulmonary involvement may not initially be recognized as a manifestation of inflammatory muscle disease. Each subgroup of IIM may present with a variety of extramuscular features that can complicate diagnosis and alter therapy and prognosis. This is particularly true for the pulmonary, GI, and cardiac manifestations and when cancer is associated with myositis. For these reasons, such features of IIM should be carefully evaluated, treated, and monitored over the course of the illness; in some cases these may play a greater role in determining the outcome of patients with IIM than the muscle involvement itself. It is hoped that in the future increased familiarity with the manifestations of the inflammatory myopathies, together with a better understanding of the underlying pathogenesis, will lead to more rapid diagnosis and more effective treatments

After careful examination, cardiac involvement can be found in certain patients with inflammatory muscle disease. The clinical significance is not always clear, although in some patients profound disturbances can become manifest. Currently, no laboratory assay can be relied on to detect cardiac disease with 100% accuracy. Cardiac troponin I is, however, the best test currently available
