The Coordinated-Transitional Care (C-TraC) Program was designed to improve care coordination and outcomes among veterans with high-risk conditions discharged to community settings from the William S. Middleton Memorial Veterans Hospital, in Madison, Wisconsin. Under the program, patients work with nurse case managers on care and health issues, including medication reconciliation, before and after hospital discharge, with all contacts made by phone once the patient is at home. Patients who received the C-TraC protocol experienced one-third fewer rehospitalizations than those in a baseline comparison group, producing an estimated savings of $1,225 per patient net of programmatic costs. This model requires a relatively low amount of resources to operate and may represent a viable alternative for hospitals seeking to offer improved transitional care as encouraged by the Affordable Care Act. In particular, the model may be attractive for providers in rural areas or other care settings challenged by wide geographic dispersion of patients or by constrained resources.

Joint hypermobility is a rarely recognised aetiology for focal or diffuse musculoskeletal symptoms. To assess the occurrence and importance of joint hypermobility in adult patients referred to a rheumatologist, we prospectively evaluated 130 consecutive new patients for joint hypermobility. Twenty women (15%) had joint hypermobility at three or more locations (¢5 points on a 9 point scale). Most patients with joint hypermobility had common musculoskeletal problems as the reason for referral. Two patients referredwith a diagnosis ofrheumatoid arthritis were correctly reassigned a diagnosis of hypermobility syndrome. Three patients with systemic lupus erythematosus had diffuse joint hypermobility. There was a statistically significant association between diffuse joint hypermobility and osteoarthritis. Most patients (65%) had first degree family members with a history of joint hypermobility. These results show that joint hypermobility is common, familial, found in association with common rheumatic disorders, and statistically associated with osteoarthritis. The findings support the hypothesis that joint hypermobility predisposes to musculoskeletal disorders, especially osteoarthritis.

Overall, serious EAMs of RA have declined among US veterans in both the inpatient and outpatient settings, with the exception of RA lung disease likely reflecting improved detection. Breakpoints in pooled EAM prevalence appear to demonstrate consistent, true declines in severe RA extra-articular disease around 2000. Future work should explore the relationship between temporal EAM trends and specific RA therapies including adoption of biological agents.

Mast cells were isolated by enzymatic digestion of synovium obtained from 48 patients with rheumatoid arthritis (RA) and 42 patients with osteoarthritis (OA). A significantly lower percentage of stainable synovial mast cells was obtained by tissue digestion from patients with clinically active RA compared with those with less active disease. The 54 patients treated with nonsteroidal antiinflammatory drugs had a significantly lower percentage of stainable synovial mast cells in cell suspension than did the other 36 patients. When anti‐IgE antibody was used as a secretagogue in vitro, significantly greater histamine release was observed from synovial mast cells of RA patients compared with OA patients. Greater histamine release in response to anti‐IgE was observed in the RA patients with more clinically active disease and those who were treated with prednisone, compared with RA patients without these features. Synovial mast cells of RA patients treated with a disease‐modifying antirheumatic drug had a significantly lower mean histamine content than did cells from patients not receiving such treatment. Our data suggest that there are differences between synovial mast cells from tissues of patients with RA and OA and suggest that synovial mast cells may be activated in clinically active RA. In addition, the data indicate an effect of systemic anti‐rheumatic therapy on mast cells isolated from synovium of patients with arthritis.

Most women with silicone implants and rheumatic complaints had normal results of serologic tests and nonspecific symptoms, suggesting no serious connective tissue disease. However, a subset of women had clinical signs and serologic tests that were unusual even for referred patients. These observations suggest, but cannot establish, that some women with silicone breast implants may develop atypical immunologic reactions.

Rheumatoid vasculitis is a rare but serious complication of rheumatoid arthritis. Herein we examine the pathophysiology, epidemiology, clinical diagnosis, and treatment of rheumatoid vasculitis. Seropositivity, specific HLA variations, and tobacco use are among the genetic and environmental predictors of rheumatoid vasculitis. Fortunately, recent reports have noted declines in the prevalence of rheumatoid vasculitis. Nevertheless, proper recognition of systemic manifestations may assist in pathologically confirming the diagnosis, determining the extent of disease, and guiding treatment. Contemporary treatment reports are discussed in the context of the ongoing debate regarding whether new agents may trigger, treat, or even prevent rheumatoid vasculitis. Evolving genetic, histopathologic, and immunologic studies partnered with ongoing clinical experience with biologics offer promise to inform future prevention and treatment of rheumatoid vasculitis.

An association between auto-immune disorders and interferon (IFN) has been reported. High levels of natural IFNalpha are present in the blood of patients with auto-immune disease and correlate with disease activity. In addition, IFNalpha treatment of humans has resulted in multiple reports of associated auto-immune phenomena. We describe a patient who underwent resection of regionally metastatic melanoma, was given adjuvant high-dose IFNalpha2b, and subsequently developed dermatomyositis. To the authors' knowledge this is the first report of dermatomyositis in association with IFNalpha treatment. We review the literature reporting associations between IFNalpha and auto-immune disease and discuss possible mechanisms by which IFNalpha may contribute to the development of auto-immune disease. High dose IFNalpha2b is more commonly prescribed since it was approved as an adjuvant treatment for patients with surgically resected high-risk melanoma. The potential for cases of IFN-associated auto-immune disease is therefore a clinical concern. Standard side effects of high-dose IFN therapy resemble symptoms of auto-immune diseases, which may make prompt diagnosis difficult. Therefore, it is important that auto-immune diseases such as dermatomyositis are recognized as potential side effects of treatment with high-dose IFNalpha.
