Severe enteropathy associated with raltitrexed and oxaliplatin chemotherapy: report of two patients experiencing this rare, potentially lethal gastrointestinal adverse event.

Among the several different combination chemotherapy regimens for the treatment of patients with metastatic colorectal cancer, oxaliplatin plus raltitrexed has shown encouraging therapeutic results and a fairly good toxicity profile. Here, we report on two patients with metastatic colorectal cancer receiving this combination therapy, which leads to severe enterocolitis and neutropenia resulting in death in one patient. One patient was a 67-year-old woman suffering from an adenocarcinoma of the sigmoid colon with multiple liver metastases.

Pharmacokinetics of telithromycin in plasma and soft tissues after single-dose administration to healthy volunteers.

By use of microdialysis we assessed the concentrations of telithromycin in muscle and adipose tissue to test its ability to penetrate soft tissues. The ratios of the area under the concentration-versus-time curve from 0 to 24 h to the MIC indicated that free concentrations of telithromycin in tissue and plasma might be effective against Streptococcus pyogenes but not against staphylococci and human and animal bite pathogens.

[Non-lipid effects of statins: myth or fact?].

Hydroxy-methylglutaryl coenzyme A reductase-inhibitors (HMG-CoA [statins]) are currently the most effective method to pharmacologically decrease total plasma cholesterol levels. A number of multicenter studies have demonstrated, that statins administered for several years lead to a significant reduction of cardiovascular events and mortality compared with placebo. Apart from the well known LDL- and cholesterol lowering effect, statins have been postulated to exert beneficial effects on mortality due to so called 'non-lipid effects'.
