Tako-Tsubo cardiomyopathy (also known as apical ballooning syndrome) is a relatively new clinical entity characterized by reversible left ventricular dysfunction. Its clinical presentation and electrocardiographic findings are similar to acute myocardial infarction but without significant coronary artery disease. Cardiotoxicity is a major complication of various anticancer drugs; however, only a few cases of Tako-Tsubo cardiomyopathy associated with anticancer drugs, including 5-fluorouracil, have been reported. ⋯ Four months later, the patient remained completely asymptomatic of any cardiac manifestations. Use of the Naranjo adverse drug reaction probability scale indicated a probable relationship (score of 8) between the patient's development of acute coronary Tako-Tsubo-like syndrome and 5-fluorouracil. Clinicians should be aware of this potential adverse effect when monitoring patients receiving chemotherapy with 5-fluorouracil.

To evaluate the effect of a previous single dose of nevirapine given to prevent mother-to-child transmission of human immunodeficiency virus (HIV) on virologic and immunologic measures after months of an antiretroviral regimen containing either efavirenz or lopinavir-ritonavir. ⋯ In this retrospective analysis of a small cohort, previous exposure to a single dose of nevirapine did not affect virologic outcomes after 6 months of either an efavirenz-based or lopinavir-ritonavir-based antiretroviral regimen. As efavirenz is one of the first-line combination antiretroviral therapies administered in Africa, it remains an option for women who received single-dose nevirapine.

To compare clinical and microbiologic outcomes in adults without cystic fibrosis who had Pseudomonas aeruginosa bronchial colonization and were receiving inhaled colistin or colistin plus tobramycin with those who were receiving inhaled tobramycin as outpatient treatment. ⋯ Results with colistin were similar to those with tobramycin for inhaled treatment of P. aeruginosa colonization in this population; however, combined use of colistin and tobramycin appeared to be associated with fewer days of hospitalization and shorter duration of antibiotic treatment. Prospective, double-blind, placebo-controlled trials of outpatient nebulized antibiotics, especially colistin plus tobramycin, should be performed to ascertain the efficacy of this therapy for treatment of P. aeruginosa colonization in patients without cystic fibrosis.

The field of critical care medicine began to flourish only within the last 40 years, yet it provides some of the best examples of collaborative pharmacy practice models and evidence for the value of pharmacist involvement in interdisciplinary practice. This collaborative approach is fostered by critical care organizations that have elected pharmacists into leadership positions and recognized pharmacists through various honors. There is substantial literature to support the value of the critical care pharmacist as a member of an interdisciplinary intensive care unit (ICU) team, particularly in terms of patient safety. ⋯ As the published evidence supporting pharmacist involvement in patient care activities in the ICU setting has increased, surveys have demonstrated an increase in the percentage of pharmacists performing clinical activities. In addition, substantial support of pharmacists has been provided by other clinicians, safety officers, and administrative personnel who have been involved with the initiation and expansion of critical care pharmacy services in their own institutions. Although there is still room for improvement in the range of pharmacist involvement, particularly with respect to interdisciplinary activities related to education and scholarship, pharmacists have become essential members of interdisciplinary care teams in ICU settings.
