Trastuzumab in the treatment of advanced breast cancer: single-center experience.

A significant number of women with advanced breast cancer fail to respond to standard-dose chemotherapy. From the beginning of 1999, 17 women with HER2 positive advanced breast cancer received Herceptin as monotherapy or in combination with paclitaxel or other non-anthracyclines. Eight (47%) women previously received high-dose chemotherapy followed by haematopoiesis stem cell rescue.

Mobilisation of cadmium by meso- and racemic-2,3-dimercaptosuccinic acid (DMSA) in rats.

A higher efficiency of cadmium binding with racemic than with meso-2,3-dimercaptosuccinic acid (rac-DMSA; meso-DMSA) was found in an in vitro speciation model by Fang et al. (1996). This finding has not yet been tested in vivo.

Combined chelation therapy in reducing tissue lead concentrations in suckling rats.

The very young are more prone to lead poisoning than adults, and the treatment with chelating agents, either as monotherapy or combined treatment, is still a matter of dispute. The purpose of this work was to evaluate the efficiency of three chelating agents administered either as monotherapies or as combined treatments in sucklings. Lead acetate (5 mg Pb kg(-1) i.

Meso-2,3-dimercaptosuccinic acid in the treatment of occupationally exposed lead workers.

The aim of this study was to evaluate the efficacy of meso-2,3-dimercaptosuccinic acid (DMSA) treatment in workers with increased lead absorption and no overt symptoms of lead poisoning. Seven occupationally lead exposed male workers with blood lead concentrations (PbB) exceeding 50 micrograms/100 ml and a positive calcium disodium ethylenediaminetetraacetate (EDTA) lead mobilization test were treated with DMSA for 19 days. Individual doses were 700 mg DMSA, three times a day from day one to five, and twice a day from day six to 19.

Contribution of lead poisoning to renal impairment.

The late effects of lead on kidney function and blood pressure were studied in 38 persons occupationally poisoned in the past and in 23 workers exposed to lead. Parameters evaluated in all subjects were: creatinine clearance, hippuran renal flow, blood lead, erythrocyte protoporphyrin, aminolevulinic acid dehydratase, and blood pressure. Out of 11 combined variables, four significant factors were identified by factor analysis.
