First Bite Syndrome

Introduction: Eagle Syndrome (ES) is caused by the ossification/calcification of the stylohyoid ligament and is associated with many different symptoms such as otalgia, restricted mouth opening, or an intrapharyngeal foreign body sensation. First-bite syndrome (FBS) is characterized by pain in the parotid and retromandibular region, when taking the first bite in a meal and occurs more or less invariably. Observation: A 50-year-old female patient presented complaining of right retromandibular pain, that irradiated to the right side of the mandible and right shoulder, only when eating for the first time a day and at the first bite. Medical history and clinical examination did not reveal any signs of cervical surgery or cervical trauma. Palpation was painful at a specific point in right retromandibular point region, the rest of the intraoral and extraoral examinations were normal. The right and left condylar x-rays (open mouth and closed mouth) revealed an elongation of both the right and left stylohyoid ligaments. Discussion: Usually, FBS occurs after cervical surgery, for example after resection of the stylohyoid ligament for ES. Our case report shows, on the contrary, FBS that was associated with ES. The pathophysiological explanation of FBS depends on an irritative or traumatic factor in the sympathetic nerve fibers of the parotid gland. Conclusion: This association allows us to present both syndromes and to carry out an up to date pathophysiological examination and therapeutic proposals concerning FBS.

С помощью гистологических методов окраски толуидиновым синим, гематоксилином и эозином и иммуногистохимических реакций на белок PGP 9.5, тирозингидроксилазу (ТГ), белок Iba-1, изучены клеточные изменения в разных отделах сердца крыс линии Wistar в возрасте 18- 23 мес. В соединительной ткани основания сердца обнаружены очаговые воспалительные инфильтраты, внутри которых выявлены PGP 9.5 и ТГ сплетения, состоящие из парасимпатических и симпатических нервных волокон. В области клапанного аппарата, на границе фиброзного кольца и миокарда правого предсердия, обнаружены патологические изменения нервных структур - дегенерация нервных пучков и зернистый распад варикозных аксонов терминального сплетения. Установлены тесные взаимоотношения аксонов терминальной нервной сети с клетками воспалительных инфильтратов и кровеносными сосудами. Определены закономерности встречаемости в различных отделах миокарда у старых животных нейроклеточных воспалительных комплексов, состоящих из нервных волокон, кровеносных капилляров и клеток-участников местного воспалительного процесса (тучных клеток, макрофагов, фибробластов, плазмоцитов). Установлен хронический характер нейрогенного воспаления в сердце при старении. Using histological methods of staining with toluidine blue, hematoxylin-eosin and immunohistochemical reactions for the PGP 9,5 protein, tyrosine hydroxylase (TH), Iba-1 protein, cellular changes in different parts of the heart of Wistar rats at the age of 18-23 months were studied. In the connective tissue of the heart base, focal inflammatory infiltrates were found, near which PGP 9.5 and TH plexuses, consisting of parasympathetic and sympathetic nerve fibers, were detected. In the area of the valvular heart apparatus, at the border of the anneau fibreux and the myocardium of the right atrium, pathological changes in nerve structures were found: degeneration of nerve fibers and granular destruction varicose axons of the terminal plexus. A close relationship has been established between axons of the terminal nervous network and cells of inflammatory infiltrates and blood capillaries. The features of the localization of neurocellular inflammatory complexes consisting of nerve fibers, blood capillaries and cells participating in the local inflammatory process (mast cells, histiocytes, monocytes, fibroblasts, plasma cells) in various parts of the myocardium in old animals are described. The chronic nature of neurogenic inflammation in the heart during aging has been established.

Mechanosensitivity of afferent sympathetic nerve fibers from the right heart and the pulmonary artery has been examined. Action potentials of the afferent fibers that responded to tapping the right heart and the pulmonary artery were derived from upper thoracic communicating rami of both sides of anesthetized dogs. The fibers were composed of myelinated Adelta fibers and unmyelinated fibers. The receptive fields of both groups of fibers were located widely in the right heart and the pulmonary artery. Myelinated fibers ceased to fire quickly whereas unmyelinated fibers continued to fire after withdrawl of a brief mechanical stimulus. In the myelinated group, the pressure threshold was 3-50, 6-58, and 3-10 mmHg for right ventricular, pulmonary and right atrial threshold was 15-58, 22-34, and 4-8 mmHg for right ventricular, pulmonary, and right atrial fibers, respectively. Spontaneous discharge of myelinated fibers was synchronous with each rise and/or fall in intracardiac or pulmonary pressure whereas that of unmyelinated fibers was irregular and independent. A rise in pressure produced by pulmonary embolization or occlusion caused an augumented discharge whereas a fall caused by caval vein occulsion eliminated the discharge. The results indicate the existence of both myelinated and unmyelinated fibers with mechanoreceptors in the right heart and the pulmonary artery.

Stylohyoid Ligament

Introduction. Eagle?s syndrome is defined as elongation of the styloid process or the stylohyoid ligament mineralization complex which consist of styloid process, stylohyoid ligament and lesser horn of hyoid bone. It is a rare entity, is not commonly suspected in clinical practice. It is characterized by recurrent facial and throat pain, dysphagia, odynophagia, parapharingeal foreign body sensation, otalgia and neck pain. Eagle?? syndrome can be treated conservatively (lacing local anesthetic into the styloid process and stylomandibular ligament attachment) or surgically. Its pathogenesis and threatment modalities are still being debated while different theories have been presented. Case report. The two traditional surgical approaches to styloidectomy (removal of the elongated portion of the styloid process) were presented the intraoral approach and the extraoral approach. We presented two cases (49 years and 34 years old males), with bilateral and unilateral elongated styloid process. The surgical treatment included unilateral right side stiloidectomy by intraoral approach in the first case and right styloidectomy by extraoral approach in the second case. In both eases post-operative course passed regularly with no complaints at regular postoperative control. Conclusion. Surgical techniques for treatment of Eagle?s syndrome have many advantages and disadvantages. We believe that the length of the styloid process or the calcified ligament is a decisive parameter for the selection of techniques and approach.

Abstract This is a brief report of a 17-year-old male who presented to the emergency department with odynophagia and a foreign body sensation in the throat after choking on a chicken wing. A soft tissue neck radiograph was performed which revealed a 4.6 centimeter linear object in the vallecula read by the radiology department as a chicken bone. The otolaryngology team was consulted and performed a nasopharyngeal laryngoscopy which did not reveal a foreign body in the upper aerodigestive tract. On physical examination, the right tonsillar fossa was tender to palpation. Upon further review of the radiograph, the right stylohyoid ligament was noted to be elongated and calcified. Thereafter, the diagnosis of Eagle syndrome was made. This case provides an important teaching point for providers by pointing out a syndrome that can mimic other disease processes. In addition, it emphasizes the importance of providers reviewing their own films.

Treatment Of Hypertension

It is well known that hypertension is an independent cardiovascular risk factor. Treatment of hypertension frequently includes administration of three or more drugs. Resistant hypertension is defined when blood pressure remains above target value despite full doses (the patient’s maximum tolerated dose) of antihypertensive medication consisting of at least three different classes of drugs including a diuretic. Pharmacological treatment of hypertension is often unsuccessful despite the increasing number of drug combinations. Uncontrolled hypertension, however, increases the cardiovascular risk. Device treatment of resistant hypertension is currently testing two major fields. One of them the stimulation of baroreceptors in the carotid sinus and the other is radiofrequency ablation of sympathetic nerve fibers around renal arteries to reduce blood pressure in drug resistant hypertension.

Abstract As chest x rays involve risks of patients falling, radiologic technologists (technologists) commonly assist patients, and as the assistance takes place near the patients, the eye lenses of the technologists are exposed to radiation. The recommendations of the International Commission on Radiological Protection suggest that the risk of developing cataracts due to lens exposure is high, and this makes it necessary to reduce and minimize the exposure. The present study investigated the positions of technologists assisting patients that will minimize exposure of the eye lens to radiation. The results showed that it is possible to reduce the exposure by assisting from the following positions: 50% at the sides rather than diagonally behind, 10% at the right side of the patient rather than the left and 40% at 250 mm away from the patient. The maximum reduction with radiation protection glasses was 54% with 0.07 mmPb and 72% with 0.88 mmPb.

Eagle Syndrome

Eagle Syndrome (ES), also termed stylohyoid syndrome or styloid syndrome, is a rare condition characterised by a cluster of symptoms related to an elongation of the styloid process (SP) of the temporal bone. These may range from mild pharyngeal foreign body sensation and dysphagia to severe orofacial pain. High clinical suspicion is necessary owing to the unspecific clinical picture and limited diagnostic clues. Until a definitive diagnosis is achieved, these patients may develop symptoms which significantly impact their quality of life. The aim of this article is to report a case of ES in which a considerable length of SP was documented. Diagnosis was made years after the initial complaints and several medical workups by different specialties. Surgical resection of the elongated process by cervical approach was the adopted treatment modality. Patient recovery and follow-up was satisfactory, with remission of the afflicting symptoms.

First Bite Syndrome

AbstractInflammatory myofibroblastic tumors (IMTs) in the head and neck region are common, but those with sympathetic trunk involvement are extremely rare. Here we present a case of cervical sympathetic trunk-centered IMT which is also accompanied by ipsilateral carotid artery, internal jugular vein, and vagus nerve involvement. The patient initially complained of an episodic painful swelling on the right side of the neck and underwent surgery. Preoperative and postoperative serum IgG4 level during 3-year follow-up time is within normal limits. Immunohistochemical study of the tumor has also revealed negativity to IgG4. Postoperative first bite syndrome (FBS) was observed. Surgery seems to be first-line therapy in the patient with IgG4-negative IMT.
