Pharmacotherapy
-
To evaluate the effect of prophylactic amiodarone on length of stay (LOS), postoperative stroke, and postoperative atrial fibrillation (POAF). ⋯ Use of the prophylactic amiodarone regimens from the AFIST trials reduced LOS by 3.0 days and frequency of POAF by 22.7%.
-
To evaluate the effects on efficacy and safety of a formulary change from granulocyte colony-stimulating factor (G-CSF) to granulocyte-macrophage CSF (GM-CSF). ⋯ The formulary change to GM-CSF was associated with a higher frequency of febrile neutropenia, resultant chemotherapy dose delays, more adverse events, and greater use of resources to manage the adverse events. These results suggest that G-CSF and GM-CSF are not therapeutically equivalent, with G-CSF having a superior safety and efficacy profile for the prevention of chemotherapy-induced neutropenic events.

A human fetus is most susceptible to teratogenic agents during the first trimester of pregnancy. Cyclophosphamide and doxorubicin are pregnancy category D agents; however, potential benefits may warrant treatment with these agents during pregnancy under special circumstances. During her first trimester of pregnancy, a 37-year-old Caucasian woman was diagnosed with stage IIB infiltrating ductal carcinoma in situ (breast cancer) that was estrogen and progesterone receptor negative and human epidermal growth factor receptor-2 positive. ⋯ The infant grew and developed normally during his first year of life and remained in good health. An objective causality assessment revealed that it was probable that the infant's adverse events (prematurity, neutropenia, and anemia) were related to his mother's doxorubicin and cyclophosphamide therapy; however, these were the only adverse events potentially linked to in utero exposure to chemotherapy during the second and third trimesters. Due to the special considerations of both mother and infant, optimal treatment for patients with pregnancy-associated breast cancer requires the expert opinion of a multidisciplinary care team.

A 52-year-old man with no previous drug allergies or skin disorders developed a widespread papulovesicular rash while receiving an antimicrobial regimen of piperacillin-tazobactam, tobramycin, and vancomycin. Skin biopsy suggested leukocytoclastic vasculitis, which responded well to antibiotic discontinuation and steroid therapy. ⋯ This case is consistent with previous reports of vancomycin-associated TEN. Any patient who develops TEN while receiving vancomycin therapy should be evaluated for possible vancomycin-induced TEN.

To determine whether use of inhaled alprostadil (PGE 1 ) or epoprostenol (PGI 2 ) significantly improved oxygenation in patients with acute respiratory distress syndrome (ARDS), and to determine whether differences between the two drugs exist with regard to oxygenation, duration of mechanical ventilation and hospitalization, adverse effects, and survival. ⋯ No statistically significant improvement in oxygenation was observed in patients receiving either PGE 1 or PGI 2 . In addition, no significant differences were found between the two prostaglandins for the variables studied. Until positive results from large, prospective studies are available, we recommend that these inhaled prostaglandins not be used to treat ARDS.
