Methotrexate (MTX) is a folic acid antagonist and cell cycle–specific antimetabolite. While still an important component of hematologic and solid tumour treatment regimens, MTX is now used in low doses for the treatment of many autoimmune disorders, including Crohn disease, rheumatoid arthritis, and psoriasis. Although MTX is generally well tolerated at low doses, serious and predictable organ ...

Methicillin-resistant Staphylococcus aureus (MRSA) is well recognized as a major cause of nosocomial infections worldwide and is associated with high morbidity and mortality rates with rapid development of resistance. MRSA has become established outside the hospital environment and is now appearing in community populations without identifiable risk factors. The traditional treatment for infecti...

The in vitro activity of R-3746, an iminomethoxy aminothiazolyl cephalosporin with a CH2OCH3 moiety at position 3, was compared with those of other antibiotics. R-3746 inhibited the majority of hemolytic streptococci (groups A, B, C, F, and G) and Streptococcus pneumoniae at less than 0.06 micrograms/ml, which was comparable to the activity of amoxicillin, 2- to 8-fold more active than cefixime...
