Intra-articular Triamcinolone Versus Hyaluronate Injections for Low Back Pain With Symptoms Suggestive of Lumbar Zygapophyseal Joint Arthropathy: A Pragmatic, Double-Blind Randomized Controlled Trial.

Objective: The aim of the study was to compare hyaluronate with triamcinolone injections in treating chronic low back pain suggestive of lumbar zygopophyseal joint arthropathy.

Design: This was a prospective, double-blind, randomized controlled trial. Thirty subjects were randomly assigned to receive bilateral L3-S1 lumbar zygopophyseal joint injections with triamcinolone (KA) or Synvisc-One (HA).

Development of Systemic Inflammatory Polyarthritis After Zygapophyseal Joint Injection With Hylan G-F 20 (Synvisc-One).

Hylan G-F 20 (Synvisc-One) is a hyaluronic acid derivative used for viscosupplementation of synovial fluid in osteoarthritic joints. Injection of hylan G-F 20 is Federal Drug Administration approved for use in knee osteoarthritis and is generally well tolerated with few reported adverse effects, the most common being local pain or swelling. We present the case of a 72-year-old man with bilateral, diffuse, joint pain and swelling with elevated inflammatory markers suggestive of a systemic inflammatory polyarthropathy that developed acutely 2 days after lumbar zygapophyseal joint injection with hylan G-F 20.

A Novel Approach to Improving Fat Delivery in Neonatal Enteral Feeding.

Continuous infusion systems used for enteral nutrition support in the neonatal intensive care unit deliver as little as 60% of the fat in human milk to the neonate. This study determined the effect of mixing common feedings for preterm infants in the feeding bag and tubing on fat losses during enteral feeding. Laboratory models were developed to assess the contribution of various mixing techniques to delivered fat content.
