A noninvasive renal fungus ball caused by Rhizopus--a previously unreported manifestation of zygomycosis.

We describe the first reported case of renal zygomycosis presenting as an isolated fungus ball (bezoar) without renal parenchymal invasion. Since all previous descriptions of renal involvement have discussed tissue invasion, our case is unique in that the infection was confined solely in the renal pelvis and extended to the distal ureter without signs of contiguous renal infection. Our patient later developed renal insufficiency while receiving amphotericin B Lipid Complex (ABLC).

Recent advances in the treatment of infections due to resistant Staphylococcus aureus.

Purpose Of Review: This paper reviews recent data on the treatment of infections caused by drug-resistant Staphylococcus aureus, particularly methicillin-resistant S. aureus (MRSA). This review will focus on new findings reported in the English-language medical literature from June 2003 to September 2004.
