Novel treatment of first bite syndrome using botulinum toxin type A

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 8 2009
Byung-Joo Lee MD
Abstract Background First bite syndrome is the development of pain in the parotid region after the first bite of each meal and can be seen after surgery of the parapharyngeal space. The purpose of this study is to evaluate the efficacy of intraglandular injection of botulinum toxin type A (BTA) in patients with first bite syndrome. Methods Five patients with first bite syndrome developed after head and neck surgery were treated by injection of BTA into parotid gland. All patients completed a 4-item quality-of-life survey with a 10-point response scale designed to measure outcome of intraglandular injection of BTA. Results The first bite syndrome without or with sialogogue and degree of interference with daily activity with or without eating or drinking improved significantly at 1 and 3 month after injection (p < .05). Conclusion The BTA injection into affected parotid gland produces a decrease in the severity of first bite syndrome and improves the patient's quality of life. © 2009 Wiley Periodicals, Inc.

Does client size affect cleaner fish choice of client?

JOURNAL OF FISH BIOLOGY, Issue 6 2005
An empirical test using client fish models
To determine whether the choice of client fishes in the cleaner fish Labroides dimidiatus was influenced by client size, cleaner fish were given a choice of equal amount of food spread on large and small client redfin butterflyfish Chaetodon trifasciatus models. All large models received bites from cleaners compared to 27% for small models. Seventy-nine per cent of cleaners took their first bite from the large fish model. The results suggest that client size may affect cleaner fish choice. [source]

,The first bite of the cherry' Intra-oral manipulation prior to the first bite in humans

JOURNAL OF ORAL REHABILITATION, Issue 7 2001
J. F. Prinz
The breakdown of food in the mouth during mastication can be described in terms of two parameters: a breakage function, which describes the fragmentation of food after a bite, and a selection function which defines the probability of particle fracture. The non-zero value of the selection function depends on the manipulation of food particles by the tongue. Little, however, is known about this. As a first step, this study investigated the manipulation of wax sheets of differing sizes and shapes by the tongue after ingestion. It was found that subjects tended to orientate rectangular and square wax wafers so that the long axis of the particle was parallel to the tooth row, independent of the initial orientation given when they were introduced into the mouth. Circular wafers were randomly oriented relative to initial orientation. If this could be extrapolated to the start of mastication, then it suggests that the tongue tends to align food particles so that the post-canines produce close to the greatest surface area possible by fragmenting them along their longest axis.

EFFECTS OF TEXTURAL CHANGES IN COOKED APPLES ON THE HUMAN BITE, AND INSTRUMENTAL TESTS

JOURNAL OF TEXTURE STUDIES, Issue 5-6 2003

A multiple-point sheet sensor was used to measure the bite force applied to raw and cooked apple specimens during the first bite with incisors. Wedge penetration tests were compared with human bite measurements on the same samples. The shape of the force-time curves during biting of cooked apples clearly differed from that for raw apples. The first curve of cooked apple biting became jagged, and the maximum force was reduced. The second curve emerged following the first curve in most subjects as a characteristic feature of cooked apple biting, whereas it was not seen in the bite curve of a raw specimen or the wedge penetration curve of a cooked specimen. The maximum force for tissue fracture decreased for cooked apples, but the duration of biting increased. No adequate counterparts for the impulse of biting could be obtained from the load-displacement curves of the wedge penetration tests. The existence of parameters only measurable by bite tests and not by mechanical tests suggests the necessity of directly measuring the human bite. [source]

EFFECT OF SAMPLE THICKNESS ON THE BITE FORCE FOR APPLES

JOURNAL OF TEXTURE STUDIES, Issue 3 2003
HARUKA DAN
The thickness of a piece of food and its mechanical properties affected the bite force. A multiple-point sheet sensor was used to measure the bite force applied to apple specimens of various thicknesses during the first bite with incisors. The results of wedge penetration tests on the same samples were compared with results of the bite measurements. The maximum bite force increased with the sample thickness for two apple varieties, though the maximum load measured by the wedge penetration test did not change. Therefore, it is important to consider that not only the mechanical properties but also the thickness of the sample affects the required bite force. [source]

First-Bite Syndrome After Resection of the Styloid Process,

THE LARYNGOSCOPE, Issue 1 2007
Claudio R. Cernea MD
Abstract Background: First-bite syndrome (FBS) may occur after operations on parapharyngeal space. The main symptom is excruciating pain only after the first one or two bites of meals. Objective: The objective of this article is to report a case of FBS after resection of the styloid process (SP). Case Report: This 51-year-old woman had a 4-month history of pain on her left neck. Computed tomography scan showed a left hypertrophic SP. A diagnosis of Eagle syndrome (ES) was then established. She underwent excision of the left SP through a lateral cervicotomy. Postoperative recovery was uneventful with pain relief. However, 2 months postoperatively, intense pain appeared related to the first bite in every meal. She received 800 mg carbamazepine per day with good pain control. Medication was discontinued after 2 years with no further relapse. Conclusions: This is the first report on FBS after surgical treatment of ES. It is important to remember the possibility of the diagnosis and to maintain the patient under heavy specific medication, sometimes for longer periods. [source]
