This article provides an overview of the evidence on the ways racism can affect the disproportionate rates of cardiovascular disease (CVD) in African Americans. It describes the significant health disparities in CVD for blacks and whites and suggests that racial disparities should be understood within the context of persistent inequities in societal institutions and relations. Evidence and potential pathways for exploring effects of 3 levels of racism on cardiovascular health risk factors and outcomes are reviewed. ⋯ Few population-based studies have examined the relationship between racism and CVD. The findings, though suggestive of a positive association, are neither consistent nor clear. The research agenda of the Jackson Heart Study in addressing the role of racism in CVD is presented.

Strongyloidiasis stercoralis hyperinfection presenting as vasculitic-like skin lesions is rare. An autoinfection cycle allows intestinal strongyloidiasis, usually a benign infection, to persist for many decades. We report a woman with disseminated S stercoralis infection presenting as nonpalpable purpuric skin rash and syndrome of inappropriate secretion of antidiuretic hormone (SIADH). ⋯ Serious or fatal infection can occur in patients with strongyloidiasis who were treated with immunosuppressive drugs. Stool specimen screening and/or serological tests for S stercoralis infection in patients who require immunosuppressive therapy helps to prevent complications before embarking on such treatment. Unexplained hyponatremia, severe hypoalbuminemia without proteinuria, and unusual skin rashes, especially over the lower aspect of the abdomen and upper aspects of the thighs, in persons living in areas endemic to S stercoralis should raise suspicion of S stercoralis infection.

Computed tomography (CT) can play a vital role in the diagnosis and staging of patients with acute pancreatitis. However, according to current guidelines, a CT examination should not be performed in all patients. We assessed the use of CT scanning in the evaluation of patients with acute pancreatitis at an urban teaching hospital. ⋯ In 1 teaching institution, physicians ordering CT for the evaluation of acute pancreatitis frequently do so without regard to the severity of patient illness. These examinations may prolong the length of hospitalization. Continued refinement and dissemination of guidelines for the diagnostic evaluation of acute pancreatitis is needed.

Takayasu arteritis is an uncommon disease with a variety of presentations. We report a case of Takayasu arteritis with a presentation of a pulmonary-renal syndrome in a 22-year-old woman. She presented in acute respiratory failure with hemoptysis and acute renal failure; interestingly, however, the renal biopsy was normal. ⋯ Percutaneous transluminal angioplasty of the left renal artery normalized kidney function. The initial presentation of Takayasu arteritis as a pulmonary-renal syndrome with severe acute renal failure and diffuse pulmonary hemorrhage is unusual; to our knowledge, this has not been described previously in the literature. We provide a clinical review of Takayasu arteritis and a discussion of systemic manifestations pertinent to the case.
