RESUMEN
OBJECTIVES: Poly(amidoamine) dendrimers have been widely investigated as potential nanomaterials that can enhance the skin permeation of topically applied drugs. This article reviews the studies that have used dendrimers as penetration enhancers and examines the mechanisms by which enhancement is claimed. KEY FINDINGS: A wide range of studies have demonstrated that, in certain circumstances and for certain drugs, the incorporation of dendrimers into a topically applied formulation can significantly increase the amount of drug passing into and through the skin. In some cases, dendrimers offered little or no enhancement of skin permeation, suggesting that the drug-dendrimer interaction and the selection of a specific dendrimer were central to ensuring optimal enhancement of skin permeation. Significant interactions between dendrimers and other formulation components were also reported in some cases. SUMMARY: Dendrimers offer substantial potential for enhancing drug delivery into and across the skin, putatively by mechanisms that include occlusion and changes to surface tension. However, most of these studies are conducted in vitro and limited progress has been made beyond such laboratory studies, some of which are conducted using membranes of limited relevance to humans, such as rodent skin. Thus, the outcomes and claims of such studies should be treated with caution.
RESUMEN
The concept of the second victim, described as the sense of victimization of health care professionals following the exposure to a traumatic, unanticipated medical error, was first introduced in 2000 by Albert W. Wu. Since then, the concept has gained immense traction and inspired the generation of assistance programs for second victims. With most second victim occurrences resulting from medication errors, pediatric pharmacists are at a high risk of experiencing second victim phenomenon. Second victims may experience both psychological and physical symptoms of distress often akin to post-traumatic stress disorder. Typical trajectories for second victims, as well as typical support needs, have been previously described, with several organizations responding by creating formal programs designed to support their staff in the events of traumatic workplace experiences. Most support programs involve peer-to-peer support, group sessions, and programs designed to increase coping skills. Additional resources are available for health care workers who do not have formalized support programs at their institution, although these are limited. Despite these resources, institutions across the country have room for additional growth in their support of employees who become second victims to tragedy.
