#FIRST BITE SYNDROME CAUSES FREE#

Viral and bacterial conjunctivitis can be highly contagious and it is important that a doctor, optometrist or pharmacist diagnoses the exact cause to ensure you get the right treatment. This is due to inflammation of the eye’s clear outer layer (known as the conjuctiva) and the inside of the eyelid.Īllergic conjunctivitis may be seasonal, or triggered by specific allergens, for example, pollen or animal dander. One or both eyes may be watery, sore or itchy, sometimes with sticky white or yellow discharge. Related information on Australian websitesĬonjunctivitis, sometimes known as ‘pink eye’ or ‘sticky eye’, is a common condition where the white part of the eye becomes pink or red.What are the symptoms of conjunctivitis?.Your doctor or optometrist can tell you the likely cause of your conjunctivitis, if it’s contagious, and the best treatment for your type of conjunctivitis.

Conjunctivitis can be caused by bacterial or viral infection, allergy, or irritants such as dust or chemicals.Conjunctivitis is a common condition where the white part of the eye becomes pink or red.Conjunctivitis is sometimes known as ‘pink eye’ or ‘sticky eye’.This can also minimize salivation by reducing the hyper-stimulation and exaggerated myoepithelial cell contraction. There is evidence that Botulinum toxin type A injection causes improvement of symptoms by inducing parasympathetic nerve paralysis of the parotid gland. A majority of these symptoms resolve over time. It is currently thought this is likely due to sympathetic denervation of the parotid gland due to severing of the CSC resulting in hypersensitivity of the sympathetic receptors. With subsequent bites, the pain often decreases. Botulinum toxin was injected within the parotid gland for symptom management.ĭiscussion: In First Bite Syndrome, pain in the parotid area can be severe with the first bite of food. Following right parotid gland ultrasound examination, the patient was diagnosed with First Bite Syndrome. Approximately one month later, the patient complained of discomfort in her mouth and jaw on initiating a meal. Fiber-optic laryngoscopy revealed subtle right VC weakness that improved by post-operative day #5. On post-operative day #1, the patient had normal tongue mobility, intact CN 7 function, slight ptosis of the right eye and symmetric pupils without miosis. Histopathologic examination revealed the mass to be likely consistent with a schwannoma. It measured 5.7 cm in the largest dimension and was attached to a nerve bundle, possibly the CSC.

The right-sided mass was free from the jugular vein, carotid artery, and CN 10. The patient consented to mass excision and right neck dissection that was performed by an otolaryngologist and cardiovascular surgeon. CT demonstrated the mass as measuring 3.6 x 3.5 x 4.9 cm with close adherence to the right carotid artery. Flexible fiber-optic laryngoscopy revealed R vocal cord (VC) sluggishness with poor abduction. The mass was non-tender and firm with a 4-5 cm diameter oriented vertically. The patient complained of locally compressive symptoms including bilateral neck pain, dizziness, dysphagia and hoarseness. Post-operative complications involved with removing the CSC include Horner’s syndrome (almost inevitable) and First Bite Syndrome.Ĭase Description: An 80-year-old female presented with a 7-year history of an enlarging right neck mass followed serially over time with moderate growth. Although cervical sympathetic chain (CSC) schwannomas are uncommon, they are known for their ability to mimic the physical and radiologic findings of carotid body tumors. Introduction: Most schwannomas, other than those associated with neurofibromatosis, occur in the para-pharyngeal space often originating from Cranial nerves (CN) 9-12 or the sympathetic chain.
