INTRODUCTION Patients with human immunodeficiency virus (HIV) have various coagulation abnormalities as well as increased risk for development of clinical thrombosis and subsequent embolic events. We report acute lower-leg ischaemia caused by spontaneous thromboembolism with no identifiable risk other than HIV infection in a black African male. Physicians should be aware that thromboembolic art...

Leriche syndrome presents as a triad of claudication, erectile dysfunction, and decreased distal pulses. This syndrome is a well-recognized entity in the current literature; however, our case report illustrates that even with a severe ostial lesion of the inferior mesenteric artery, the vessel was able to provide perfusion to bilateral lower extremities. The patient presented with symptoms of p...

Abstract interpretation has a reputation of being a kind of “black art,” and consequently difficult to work with. This paper describes a twenty-year quest by the first author to address this issue by raising the level of automation in abstract interpretation. The most recent leg of this journey is the subject of the second author’s 2014 Ph.D. dissertation. The paper discusses several different ...

Acathosis nigricans (AN) typically presents as symmetric, brownish-black, velvety, hypertrophic, verrucous, and at times papillomatous plaques most commonly involving the flexural sites [1]. It is a cutaneous marker, most frequently of insulin resistance and less frequently of malignancy [2]. AN has been classified into 8 types: benign, obesity-related, syndromic, malignant, unilateral, acral, ...

A 69-year-old woman presented with right leg weakness and ataxia. CT angiogram revealed a 6-mm left middle cerebral artery (MCA) aneurysm. Intracranial vessel wall MRI (IVWM) (figure) showed ischemic strokes in the left MCA region, inflammatory changes in the aneurysmal wall, and adjacent atherosclerosis. IVWM is a highresolution black-blood MRI technique that allows visualization of the arteri...

BACKGROUND Racial differences in cardiovascular risk factors do not fully explain the higher prevalence of lower-extremity peripheral arterial disease (PAD) in black adults. OBJECTIVE We sought to determine whether any of this excess risk may be explained by vitamin D status, which has been widely documented to be lower in blacks than in whites. DESIGN This population-based cross-sectional ...
