Both patient- and physician-related factors have been shown to explain variability in the outcomes of antihypertensive treatment. Total cardiovascular risk (TCVR) is increasingly used as a determinant of treatment effectiveness but has also been proposed as a treatment outcome. To our knowledge, no studies have reported how antihypertensive treatment impacts blood pressure and TCVR outcomes. ⋯ Regimens that include SPC amlodipine/valsartan formulations are effective in reducing BP and TCVR in a real-world observational setting. Hierarchical modeling identified patient- and physician-related determinants of BP values and TCVR change, as well as independent predictors of uncontrolled BP and reduced TCVR. TCVR is a scientifically feasible and clinically relevant effectiveness outcome of antihypertensive treatment.

To review the safety and efficacy of nebulized antibiotics for refractory bacterial chronic rhinosinusitis (CRS) in adults. ⋯ Based on current studies, use of nebulized antibiotics for refractory CRS cannot be recommended at this time. Although supportive evidence is limited, nebulized antibiotics appear to improve rhinosinusitis symptoms in some patients with minimal adverse effects. With further studies, culture-directed nebulized antibiotic therapy may be a treatment option in patients with CRS refractory to conventional treatments.

Therapeutic drug monitoring is usually required for safe and effective administration of vancomycin. However, dosing recommendations from published guidelines are not suitable in achieving therapeutic vancomycin concentrations in a timely manner in patients with normal renal function. ⋯ A delay in attaining target trough concentrations was observed in a significant proportion of patients. Pharmacokinetic modeling software is a potential tool to improve the timeliness of achieving adequate dosing by allowing concentrations to be determined prior to steady-state. The program was able to predict vancomycin concentrations across a heterogeneous patient population with little systematic bias, but only moderate precision.

Acetaminophen overdose is the most common pharmaceutical poisoning in the US. The labeled dosing regimen for Acetadote, the only intravenous N-acetylcysteine (IV-NAC) product approved by the Food and Drug Administration (FDA) for treatment of acetaminophen toxicity, is a complex 3-step process that produces frequent medication errors. We have been using an off-label, uncomplicated dosing regimen consisting of a standard preparation of IV-NAC 30 g in 1 L of 5% dextrose in water, with a 150-mg/kg loading dose administered over 1 hour followed by an infusion of 14 mg/kg/h for 20 hours. ⋯ This single intravenous bag protocol is effective and well tolerated, and there is infrequent interruption of therapy. The overall rate of administration errors is similar to that in reports on the FDA regimen; thus, our protocol may be an acceptable alternative.

To report a case of persistent hiccups associated with epidural ropivacaine in a newborn infant. ⋯ Clinicians should consider the potential of neurotoxicity, manifested as persistent hiccups, when epidural ropivacaine is administered to young infants.
