Comparative Study
Clinical decision support tools: performance of personal digital assistant versus online drug information databases.
To evaluate personal digital assistant (PDA) drug information databases used to support clinical decision-making, and to compare the performance of PDA databases with their online versions. ⋯ Online and PDA drug information databases assist practitioners in improving their clinical decision-making. Lexi-Drugs performed significantly better than all of the other PDA databases evaluated. No PDA database demonstrated superiority to its online counterpart; however, the online versions of Clinical Pharmacology and Micromedex were superior to their PDA versions in answering questions.

Candida endophthalmitis is a sight-threatening manifestation of disseminated candidiasis. The occurrence of endogenous candida endophthalmitis in patients with candidemia has ranged from 0-45% in the published literature. In critically ill patients, it has even been associated with increased mortality. ⋯ Voriconazole may be a particularly attractive agent to consider for infections with fluconazole-resistant, voriconazole-susceptible strains. The current patchwork of animal studies and small patient reports provide clinicians with some insight into the role of newer agents in the treatment of candida endophthalmitis. In general, it appears that chorioretinitis infections can be more readily cured with most systemic antifungal agents, whereas more aggressive treatment, often including vitrectomy with or without intra-vitreal antifungal administration, is needed for patients with endophthalmitis with vitritis.

This overview of Parkinson's disease is designed to serve as a background to the discussion elsewhere in this supplement on the pharmacotherapy used in its management. Parkinson's disease is a common progressive neurodegenerative condition associated with significant disability and negative impact on quality of life. Although the cause of Parkinson's disease is unknown, the pathologic manifestation involves the loss or dysfunction of dopaminergic neurons in the substantia nigra pars compacta. ⋯ Postural instability and gait abnormalities occur in more advanced disease. Although there is no cure for Parkinson's disease, a number of pharmacologic treatments are available for managing the motor and nonmotor symptoms. Research is under way to assess the disease-modifying ability of both standard and newer treatments.

To examine the effect of previous outpatient use of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) and/or angiotensin II receptor blockers (ARBs) on 30-day mortality in patients hospitalized with sepsis. ⋯ Use of statins and/or ARBs before admission was associated with decreased mortality in patients hospitalized with sepsis. Further research is needed to determine if these drugs might be started on admission for those with sepsis.

Significant advances have been achieved over the past few decades regarding comprehension of the pathogenesis of pulmonary arterial hypertension (PAH). The development of new agents and use of existing drug therapies have targeted the underlying abnormalities and pathways leading to progression of PAH. Milrinone, a phosphodiesterase inhibitor, remains a therapeutic option. ⋯ After 8 days of therapy, the patient's PAH symptoms improved without compromising her mean arterial pressure and heart rate. Nebulized milrinone in addition to inhaled nitric oxide and low-dose intravenous treprostinil may have played a major role in the acute management of her PAH crisis. Further studies are needed to assess the role of nebulized milrinone in patients with PAH.
