The endothelium is a specific target for Bartonella henselae, and endothelial cell infection represents an important step in the pathogenesis of cat scratch disease and bacillary angiomatosis. Mechanisms of Bartonella-endothelial cell interaction as well as signaling pathways involved in target cell activation were analyzed. B. henselae strain Berlin-1, isolated from bacillary angiomatosis lesi...

J Lipa, W Peters, V Fornasier, B Fisher. Bacillary angiomatosis: A unique cutaneous complication of HIV infection. Can J Plast Surg 1995;3(2):96-101. As the prevalence of human immunodeficiency virus (HIV) infection increases, so does the recognition of unusual manifestations of this syndrome. This study describes two patients who presented with a unique, rare, cutaneous manifestion of HIV infe...

The CT and MR features of cortical calcification and meningeal angiomatosis are typical of Sturge-Weber-Dimitri disease but are unusual in children less than 1 year of age. This case describes a child presenting with both of these features bilaterally in the neonatal period and represents an unusual presentation of this disorder.

Gorhams disease, also known as massive osteolysis or vanishing bone disease is an extremely rare bone disease. It is characterized by angiomatosis with adjacent bone resorption. We report an 8-years old boy with the disease who was managed successfully with alpha 2b interferon therapy.

SltirgeWeber Disease With Subarachnoid Hemorrhage • A healthy adult with a nevus flammeus presented with a subarachnoid hemorrhage. Cerebral arteriography demonstrated vascular anomalies typical of encephalofacial angiomatosis (Sturge-Weber disease). A review of the literature failed to disclose a welldocumented case of subarachnoid hemorrhage in this condition. Additional

Bartonella henselae, a zoonotic agent, induces tumors of endothelial cells (ECs), namely bacillary angiomatosis and peliosis in immunosuppressed humans but not in cats. In vitro studies on ECs represent to date the only way to explore the interactions between Bartonella henselae and vascular endothelium. However, no comparative study of the interactions between Bartonella henselae and human (in...
