Vocal cord dysfunction (i.e., vocal cords closing when they should be opening, particularly during inspiration) should be suspected in patients presenting with inspiratory stridor or wheezing; sudden, severe dyspnea (without hypoxia, tachypnea, or increased work of breathing); throat or chest tightness; and anxiety, particularly in females. Common triggers include exercise, asthma, gastroesophageal reflux disease, postnasal drip, upper or lower respiratory tract infection, and irritants. Nasolaryngoscopy and pulmonary function testing, with provocative exercise and methacholine, can help diagnose vocal cord dysfunction and are helpful to evaluate for other etiologies. ⋯ Therapeutic breathing maneuvers and vocal cord relaxation techniques are first-line therapy for dyspnea that occurs with vocal cord dysfunction. A subset of vocal cord dysfunction leads to dysphonia, as opposed to dyspnea, secondary to abnormal laryngeal muscle spasms (vocal cord closure is less severe). OnabotulinumtoxinA injections may be helpful for spasmodic dysphonia and for treating dyspnea in certain cases, although evidence is limited.

Medical consultations before dental procedures present opportunities to integrate cross-disciplinary preventive care and improve patient health. This article presents recommendations related to patients with certain medical conditions who are planning to undergo common dental procedures, such as cleanings, extractions, restorations, endodontic procedures, abscess drainage, and mucosal biopsies. Specifically, prophylactic antibiotics are not recommended for preventing prosthetic joint infections or infectious endocarditis except in certain circumstances. ⋯ Although patients undergoing chemotherapy may receive routine dental care, it should be postponed when possible in those currently undergoing head and neck radiation therapy. A detailed history of head and neck radiation therapy should be provided to the dentist. Multimodal, nonnarcotic analgesia is recommended for managing acute dental pain.
