Chronic cough following cardiac transplantation: vagal Mitempfindung?
نویسندگان
چکیده
Since operation a cardiac transplant recipient has suffered from chronic, non-productive but intense coughing spells triggered by stimulation of the right external ear. This demonstrates the unusual phenomenon of acquired aberrant sensory referral.

Arnold's nerve cough reflex: evidence for chronic cough as a sensory vagal neuropathy.
Arnold's nerve ear-cough reflex is recognised to occur uncommonly in patients with chronic cough. In these patients, mechanical stimulation of the external auditory meatus can activate the auricular branch of the vagus nerve (Arnold's nerve) and evoke reflex cough. This is an example of hypersensitivity of vagal afferent nerves, and there is now an increasing recognition that many cases of refr...
متن کاملVagal Paraganglioma Presenting as a Neck Mass Associated with Cough on Palpation
A 70-year-old female presented with a neck mass and sporadic dry cough, often leading to fits of coughing severe enough to cause vomiting. The patient reported that touching the mass triggered the cough. On examination, a 2.5 cm right-sided level two neck mass deep to the sternocleidomastoid was present. Palpation of the mass immediately triggered coughing. Cross-sectional imaging proposed vaga...
متن کاملVagal cardiopulmonary reflexes after left ventricular deafferentation.
BACKGROUND Cardiac transplantation and chronic myocardial infarction interrupt vagal afferent nerve fibers, which originate mainly from the ventricles. Marked abnormalities of reflexes mediated by cardiopulmonary receptors with vagal afferent fibers have been demonstrated after both cardiac transplantation and chronic myocardial infarction. The relation between these reflex abnormalities and ve...

OBJECTIVE The objective of this prospective, randomized, controlled study (N = 28) was to evaluate the effectiveness of amitriptyline versus cough suppressants in the treatment of chronic cough resulting from postviral vagal neuropathy. METHODS Patients were selected based on a clinical history consistent with postviral vagal neuropathy and a history of an antecedent upper respiratory tract i...
متن کاملShort-term vagal nerve stimulation improves left ventricular function following chronic heart failure in rats
Increasing numbers of animal and clinical investigations have demonstrated the effectiveness of long-term electrical vagal nerve stimulation (VNS) on chronic heart failure (CHF). The present study investigated the effects of short-term VNS on the hemodynamics of cardiac remodeling and cardiac excitation-contraction coupling (ECP) in an animal model of CHF following a large myocardial infarction...
