Nontropical pyomyositis is rare and usually associated with immunodeficiency virus (HIV) infection. This study assessed manifestations and response to treatment of nontropical pyomyositis in an area with a high prevalence of HIV seropositivity. We undertook a chart review of eight consecutive patients treated for pyomyositis—primary infection of skeletal muscles—from 1988 through 1998. All patients complained of myalgia; four (50%) had fever and six (75%) had leukocytosis. Muscles involved were deltoid, quadriceps, gluteus, and psoas. Six (75%) patients had identifiable risk factors for pyomyositis: HIV seropositivity (two), history of intravenous drug abuse (one), chronic paraplegia and malnutrition (one), diabetes and chronic renal failure (one), and leukemia (one). One patient had had streptococcal pharyngitis previously but was otherwise healthy; another, a 2-year-old, had no evidence of underlying disease. Staphylococcus aureus was the most common organism isolated (50%). Four patients were treated with incision and drainage plus antibiotics; the remaining four patients were treated with intravenous antibiotics only; all recovered. Nontropical pyomyositis, which is often associated with HIV seropositivity or chronic illness, has a favorable outcome. Treatment can be effective even without surgical intervention.
Visceral artery aneurysms (VAAs) often rupture and cause serious morbidity or death. The purpose of this study was to identify conditions associated with VAA in a series of 30 patients treated at our institution from 1988 through 1998. Demographics, types of aneurysms, associated conditions, diagnoses, treatments, and outcomes were recorded and analyzed. Thirty patients (16 men and 14 women) with VAA were identified. The arteries involved were splenic (eight), renal (ten), hepatic (nine), hypogastric (one), celiac (one), and pancreaticoduodenal (one). Five of eight (63%) splenic artery aneurysms occurred in women; however, gender was not a factor in other aneurysmal groups. Splenic artery aneurysm also was associated with cirrhosis in four of the eight (50%) patients. Five of the nine (56%) hepatic artery aneurysms were associated with cirrhosis; two of these were pseudoaneurysms that occurred after liver transplantation. Five of ten (50%) renal artery aneurysms were associated with juxtarenal abdominal aortic aneurysms. Celiac and pancreaticoduodenal aneurysms were associated with gastrointestinal bleeding. Treatments included surgery (19), embolization (eight), and observation alone (three). These data demonstrate that association with other conditions varies according to subgroups of VAA. Despite advances in diagnosis and therapy the heterogeneity of VAA suggests that management must remain individualized.
Finding a suitable conduit for lower extremity arterial bypass can be a challenge, especially when the greater saphenous vein has been used for other bypasses. Several different types of conduits have been tried with variable success rates. Autologous vein grafts seem to have a higher patency rate than prosthetic grafts. In this article, a case is presented in which a continuous loop of basilic-cephalic vein was used to bypass superficial femoral artery to dorsalis pedis. This innovative conduit has the advantage of being autologous and without any intervening venovenous anastomoses and its associated complications. A review of such vein loop grafts and other types of conduits is presented in the text.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
