We conducted the current study to search for subclinical atherosclerosis in patients with rheumatoid arthritis (RA) without clinically evident atherosclerosis or its complications who had been treated for a long duration, and to assess whether demographic or clinical factors affect the development of atherosclerotic disease. Forty-seven white patients fulfilling the 1987 American College of Rheumatology classification criteria for RA were recruited from Hospital Xeral-Calde, Lugo, Spain. Patients were required to have been treated for at least 5 years, including current treatment with 1 or more disease-modifying antirheumatic drugs. ⋯ Also, RA patients with carotid plaques had a significantly longer disease duration (mean, 21.0 yr) and more extraarticular manifestations (63%) than those without plaques (mean, 12.7 yr and 26%, respectively). Age at the time of the study and disease duration were the best predictive factors for the development of severe morphologic expression of atherosclerotic disease. The present study confirms an increased frequency of severe subclinical atherosclerotic findings in long-term actively treated RA patients from northwest Spain.

Since the 1990s, changing trends have been documented in species distribution and susceptibility to bloodstream infections caused by Candida species in cancer patients. However, few data are available regarding the association between in vitro antifungal susceptibility and outcome of candidemia in this patient population. We therefore evaluated the association of in vitro antifungal susceptibility and other risk factors with failure of initial antifungal therapy in cancer patients with candidemia. ⋯ Eighty patients were evaluable for outcome analysis. In multivariate analysis, the following factors emerged as independent predictors of failure of initial antifungal therapy: leukemia (p = 0.01), bone marrow transplantation (p = 0.006), and intensive care unit stay at onset of infection (p = 0.02). Inappropriate antifungal therapy, as defined by daily dose and in vitro susceptibility, was not shown consistently to be a significant factor (it was significant in multivariate analysis, p = 0.04, but not in univariate analysis), indicating the complexity of the variables that influence the response to antifungal treatment in cancer patients with candidemia.

Review Case Reports
The clinical spectrum of retroperitoneal hematoma in anticoagulated patients.
Bleeding into the retroperitoneal space is a serious complication of anticoagulation. The incidence may be on the rise due to the increasing number of patients prescribed anticoagulants for atrial fibrillation and other disorders. ⋯ Thus, an adequate index of suspicion is needed to reverse anticoagulation rapidly and initiate other therapeutic measures. We reviewed the cases diagnosed at our institution and reported in the literature to delineate the clinical manifestations and course of this process.

Review Case Reports
Assessing the relationship between the use of nonsteroidal antiinflammatory drugs and necrotizing fasciitis caused by group A streptococcus.
Group A streptococcal (GAS) necrotizing fasciitis is a rapidly progressive soft tissue infection. Elderly and chronically ill individuals are at greatest risk, particularly when skin breakdown is present. Reports suggest that nonsteroidal antiinflammatory drugs (NSAIDs) increase the risk of developing GAS necrotizing fasciitis, impede its timely recognition and management, and accelerate the course of infection. ⋯ However, prospective studies do not support a risk of developing GAS necrotizing fasciitis as a result of NSAID therapy, or a worsening of established streptococcal infection. To avoid the application of NSAIDs in lieu of aggressive medical and surgical management of streptococcal fasciitis, clinicians must understand the early symptoms of GAS necrotizing fasciitis that precede visible soft tissue necrosis. A rational approach to patients presenting with localized soft tissue pain will enhance detection and therapy of this rapidly progressive, life-threatening disease.

Torsade de pointes due to noncardiac drugs: most patients have easily identifiable risk factors.
Numerous medications, including drugs prescribed for noncardiac indications, can lead to QT prolongation and trigger torsade de pointes. Although this complication occurs only rarely, it may have lethal consequences. It is therefore important to know if patients with torsade de pointes associated with noncardiac drugs have risk factors that are easy to identify. ⋯ Other risk factors were frequently present (18%-41%). Virtually all patients had at least 1 of these risk factors, and 71% of patients had 2 or more risk factors. Our study suggests that almost all patients with torsade de pointes secondary to noncardiac drugs have risk factors that can be easily identified from the medical history before the initiation of therapy with the culprit drug.
