  • Stridor in patients with rheumatoid arthritis is typically due to arthritis of the cricoarytenoid joints leading to fixation of the vocal cords in a midline position. Cricoarytenoid joint arthritis may be acute, chronic, or acute-on-chronic.[ncbi.nlm.nih.gov]
  • The suggest that chemical meningitis which also involved the cranial nerves might be held partly responsible for the laryngeal stridor.[ncbi.nlm.nih.gov]


  • The age of onset, patient history, tonal quality, and relation to the timing of the respiratory cycle is critical to the workup of a patient with stridor.[medicine.uiowa.edu]


  • For the treatment of these symptoms relief of the increase in intracranial pressure, relief of the pressure difference between intracranial and intraspinal compartments, and selection of a shunt system with a proper flow rate are important.[ncbi.nlm.nih.gov]
  • Despite treatment with steroids systemically and locally, antibiotics and an antihistamine, the stridor worsened.[ncbi.nlm.nih.gov]
  • Treatment for stridor decreased the relative risk from 2.998 to 0.147. Laryngeal stridor is a common and early clinical symptom in MSA. Early treatment for stridor is advisable to reduce mortality. Copyright 2003 S. Karger AG, Basel[ncbi.nlm.nih.gov]
  • We report three cases from the Rheumatology Department of University College Hospital, London and review the literature on the prevalence, clinical presentation, histopathological features and treatment of laryngeal involvement in rheumatoid arthritis[ncbi.nlm.nih.gov]
