For each new entry incorporated into the next edition, you will receive up to a $20 Amazon.com gift card as well as

personal acknowledgment in the next edition. Significant contributions will be compensated at the discretion of the

authors. Also, let us know about material in this edition that you feel is low yield and should be deleted.

All submissions including potential errata should ideally be supported with hyperlinks to a dynamically updated Web

resource such as UpToDate, AccessMedicine, and ClinicalKey.

We welcome potential errata on grammar and style if the change improves readability. Please note that First Aid style

is somewhat unique; for example, we have fully adopted the AMA Manual of Style recommendations on eponyms

(“We recommend that the possessive form be omitted in eponymous terms”) and on abbreviations (no periods with

eg, ie, etc). We also avoid periods in tables unless required for full sentences. Kindly refrain from submitting “style

errata” unless you find specific inconsistencies with the AMA Manual of Style or our diversity initiative as discussed

in the Foreword.

The preferred way to submit new entries, clarifications, mnemonics, or potential corrections with a valid,

authoritative reference is via our website: www.firstaidteam.com.

This website will be continuously updated with validated errata, new high-yield content, and a new online platform

to contribute suggestions, mnemonics, diagrams, clinical images, and potential errata.

Alternatively, you can email us at: firstaid@scholarrx.com.
