[Clinical pharmacist influence at hospital to prevent overdosed prescription of acetaminophen].

Objectives: The recommended daily dose of acetaminophen is limited to 60mg/kg/day with a maximum of 3g daily dose in adults weighing less than 50kg or in patients undergoing certain risk factors. This study aimed at assessing the fulfillment of those recommendations and the possible impact on the liver dysfunction at supra-therapeutic doses of acetaminophen.

Methods: This study was performed one day in 9 services.

[Pharmacists' interventions before and after prescription computerization in an internal medicine department].

Objective: To compare and analyze the number and types of pharmacist interventions when prescriptions were handwritten (period 1) or entered on 2 different computerized physician order entry systems (CPOE): Phedra (period 2) and Actipidos (period 3).

Methods: This study took place over 54 weeks (18 weeks for each period) in a 46-bed internal medicine department. Pharmacist interventions were categorized as either simple substitution to an available drug or "complex" interventions such as changing dosage (D), changing drug (M), stopping or substituting in cases of contraindication or overdosing (CO), new medication (N) and identifying errors due to CPOE (C).

Biological effects of a S/D-treated, very high purity, von Willebrand factor concentrate in five patients with severe von Willebrand disease.

A highly purified von Willebrand factor (vWf) concentrate with low factor VIII (FVIII) content was tested to evaluate its biological effects in five patients with severe von Willebrand disease (vWd). The patients were infused with a single dose of this product corresponding to approximately 65 IU vWf:RCo and approximately 11 IU FVIII:C/kg and were followed up for 48 h. The plasma levels of FVIII and vWf and the multimeric pattern of vWf were determined before and 1, 3, 6, 12, 24 and 48 h after infusion.
