Neuroimaging of Adult Lacrimal Drainage System.

The lacrimal drainage system (LDS) pathology is frequently encountered in the ophthalmology setting but is rarely discussed in the radiology literature. This is even truer for adult LDS lesions despite increase utilization of computed tomography and magnetic resonance in imaging for diagnosis of LDS pathology. The purpose of this image rich review is to highlight common adult LDS pathologies and introduce the radiologist to rare disease entities affecting this pathology rich anatomical region with emphasis on imaging findings, clinical presentation, and differential generation.

Tibial Osteomyelitis Following Prehospital Intraosseous Access.

Intraosseous (IO) access is a lifesaving alternative to peripheral or central venous access in emergency care. However, emergency physicians and prehospital care providers must be aware of the potential for infectious complications associated with this intervention. We describe the case of a HIV-negative, otherwise immunocompetent adult patient who underwent prehospital insertion of a tibial IO device. Following successful resuscitation, the patient developed tibial osteomyelitis requiring multiple operative debridements, soft tissue coverage, and several courses of prolonged antimicrobial therapy. Skin antisepsis prior to device insertion followed by early device removal are important strategies for reducing the risk of infection associated with IO access.
