Deep neck space abscesses are an uncommon but life-threatening emergency presentation to the ENT surgeon because of potential acute airway compromise.

This paper presents a novel case of a palatine tonsillar, low-flow, lymphovenous malformation pre-disposing to multifocal deep neck space collections and resultant acute airway compromise.

The Learning Health System Network clinical data research network includes academic medical centers, health-care systems, public health departments, and health plans, and is designed to facilitate outcomes research, pragmatic trials, comparative effectiveness research, and evaluation of population health interventions.

The Learning Health System Network is 1 of 13 clinical data research networks assembled to create, in partnership with 20 patient-powered research networks, a National Patient-Centered Clinical Research Network.

Herein, we describe the Learning Health System Network as an emerging resource for translational research, providing details on the governance and organizational structure of the network, the key milestones of the current funding period, and challenges and opportunities for collaborative science leveraging the network.
