Evaluation of dexmedetomidine versus propofol-based sedation therapy in mechanically ventilated cardiac surgery patients at a tertiary academic medical center.

Management of pain and sedation therapy is a vital component of optimizing patient outcomes; however, the ideal pharmacotherapy regimen has not been identified in the postoperative cardiac surgery population. We sought to evaluate efficacy and safety outcomes between postoperative mechanically ventilated cardiac surgery patients receiving dexmedetomidine versus propofol therapy upon arrival to the intensive care unit (ICU). We conducted a single center, descriptive study of clinical practice at a 20-bed cardiac surgery ICU in a tertiary academic medical center.

Everolimus: a proliferation signal inhibitor with clinical applications in organ transplantation, oncology, and cardiology.

Everolimus, a proliferation signal inhibitor in the mammalian target of rapamycin (mTOR) drug class, has many clinical applications, including in organ transplantation, oncology, and cardiology. It currently has United States Food and Drug Administration (FDA) approval for prophylaxis against rejection in de novo renal transplant recipients, treatment of renal cell carcinoma, and use as a drug-eluting stent. To review the pharmacology, pharmacokinetics, efficacy, and safety of everolimus, we performed a search of the MEDLINE database (January 1997-April 2010) for all English-language articles of in vitro and in vivo studies that evaluated everolimus, as well as abstracts from recent scientific meetings and the manufacturer.

Sedation and analgesia in the intensive care unit: evaluating the role of dexmedetomidine.

Purpose: A review highlighting the application of sedatives and analgesics in the intensive care unit (ICU) setting, with a focus on the use of dexmedetomidine, is presented.

Summary: Relevant and applicable clinical trials that resulted from a search of the literature from 1966 to July 2006 using key search terms such as dexmedetomidine, intensive care unit, sedation, delirium, and analgesia were evaluated. Many agents have been evaluated in the search of the optimal regimen for sedation and analgesia in the ICU, including opioids, benzodiazepines, propofol, and antipsychotic agents.

Azacitidine-induced interstitial and alveolar fibrosis in a patient with myelodysplastic syndrome.

A 71-year-old Caucasian man diagnosed with myelodysplastic syndrome developed interstitial and alveolar fibrosis after receiving a 7-day course of azacitidine therapy. The patient's pulmonary function began to deteriorate immediately after the administration of his chemotherapy regimen. Other potential causes of pulmonary toxicity were ruled out such as viral, fungal, and bacterial pathogens, as well as other concomitant drugs.

Efficacy and safety of low-dose valganciclovir for prevention of cytomegalovirus disease in renal transplant recipients: a single-center, retrospective analysis.

Study Objective: To evaluate the safety and efficacy of valganciclovir 450 mg/day for 6 months for cytomegalovirus (CMV) prophylaxis in renal transplant recipients.

Design: Single-center, retrospective analysis.

Setting: Urban, academic medical center.

Interaction between nesiritide and a heparin-coated pulmonary artery line during an infusion for decompensated heart failure.

Study Objective: Because it is known that intravenous nesiritide is not compatible with unfractionated heparin, we sought to determine the effect that heparin coating on a pulmonary artery catheter may have on the efficacy of a nesiritide infusion.

Methods: The efficacy of a nesiritide infusion given through a heparin-coated pulmonary artery line was compared with that of a nesiritide infusion administered in the same patient through a heparin-free peripheral line.

Results: The rate of infusion was titrated to maintain consistent hemodynamic parameters.

Calcium channel blockers as the treatment of choice for hypertension in renal transplant recipients: fact or fiction.

Posttransplantation hypertension has been identified as an independent risk factor for chronic allograft dysfunction and loss. Based on available morbidity and mortality data, posttransplantation hypertension must be identified and managed appropriately. During the past decade, calcium channel blockers have been recommended by some as the antihypertensive agents of choice in this population, because it was theorized that their vasodilatory effects would counteract the vasoconstrictive effects of the calcineurin inhibitors.

Adjuvant ketamine analgesia for the management of cancer pain.

Objective: To review the clinical literature evaluating the utilization of intravenous ketamine for the management of cancer-related pain, to summarize the data that suggest ketamine is an appropriate adjuvant method of providing analgesia and to report a case of successful pain management using ketamine in a patient with recurrent testicular cancer at our institution.

Data Sources: Primary literature was identified through a MEDLINE search (1966-March 2002), and additional information was obtained through secondary and tertiary sources.

Data Synthesis: The available data suggest that supplementation of morphine with ketamine improves analgesia in patients with cancer, and also provides insight to the controversy regarding the efficacy and adverse effects of various ketamine doses.
