Effective treatment of resistant S. pneumoniae is a growing concern. New classes of drugs, newer formulations of older drugs, combination antibiotic therapy, nonantibiotic modalities, better oversight of antibiotic usage, and enhanced preventive measures hold promise.
Porphyrias are a group of metabolic disorders that are relatively uncommon and underdiagnosed. Although the association between HIV infection and antiretrovirals with porphyria cutanea tarda is well established, there are fewer data linking HIV and the acute hepatic porphyrias. We report the first case of acute intermittent porphyria precipitated by the drugs atazanavir and ritonavir, presenting with unexplained abdominal pain.
Clostridium difficileis one of the most common nosocomial pathogens and the cause of pseudomembranous colitis in cases of prior antimicrobial exposure. Extraintestinal manifestations ofC. difficileare uncommon and rarely reported. We report the first successfully treated case of catheter-relatedC. difficileperitonitis in a patient undergoing peritoneal dialysis.
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.
