Spinal region corticosteroid injections are not associated with increased risk for influenza.

Background Context: Spinal region corticosteroid injections (CSI) are intended to act locally to relieve radicular or axial back pain, however some systemic absorption occurs, potentially placing recipients at risk for immunosuppressive effects of corticosteroids. No previous studies examine whether patients undergoing spinal region CSI are at increased risk for viral infections, particularly influenza-a common viral illness with potentially serious consequences, especially for patients with multimorbidity.

Purpose: To examine odds of influenza in patients who received spinal region CSI compared to matched controls.

Chylothorax complicating inpatient rehabilitation after thoracic spinal cord injury: a review of risk factors and anatomy for the physiatrist.

After malignancy, traumatic and surgical injuries to the upper abdomen and chest are the leading causes of chylothorax. Thoracic spine extension injury, blunt or penetrating chest trauma, anterior thoracic spine surgery, and increased intra-abdominal pressure have all been implicated in the development of chylothorax. Despite the physiatrist's frequent exposure to polytrauma and postsurgical patients, there are no case reports of chylothorax complicating inpatient rehabilitation or occurring in a patient fitted in a thoracic or lumbar orthosis.

Freiberg's disease as a rare cause of limited and painful relevé in dancers.

Freiberg's disease, or osteonecrosis of the second metatarsal head, is an uncommon cause of forefoot pain that can severely limit a dancer's relevé. Dancers may be predisposed to the condition due to repetitive microtrauma to the ball of the foot during routine dance movements. Freiberg's disease is diagnosed by history, physical examination, and plain film radiographs.
