ABSTRACT
Recurrent syncope as a complication of recurrent neck malignancy is an uncommon but well documented association. The syncope is presumed to occur when a tumor mass invades the baroreceptor within the carotid sinus or when it disrupts the afferent nerve fibers of the glossopharyngeal nerve. A 59-year-old man presented with recurrent syncope and headache. He had a wide local excision including tonsillectomy and modified left radical neck dissection for tonsilar cancer 4 years ago. A computed tomography scan revealed ill-defined lesions in left parapharyngeal, carotid space and right upper jugular region. After clinical evaluation, cardiac pacemaker was placed, but he still suffered from the syncope. Then, he received the chemotherapy with docetaxel and cisplatin. The last hypotension event occurred on day 10 of the chemotherapy. Six months after 3 cycles of chemotherapy, he remained in complete remission and resolution of syncope. We report a case in which syncope was associated with a recurrence of tonsilar cancer and successfully treated with chemotherapy.

Glossopharyngeal neuralgia with syncope as a sign of neck cancer is a very rare condition. A review of the literature revealed only 29 cases formerly reported. We present the first Brazilian case of such association. A 68-year-old man presented with paroxysmal excruciating pain over the right side of the neck, sometimes followed by syncope. Given the suspicion of recurrent tumor from a previously treated neck malignancy, a computed tomography scan was performed and a right parapharyngeal tumor was shown. Pain and syncope were successfully controlled with carbamazepine and the patient underwent palliative radiotherapy.
Neuralgia glossofaríngea com síncope como um sinal de câncer do pescoço é uma condição muito rara. Uma revisão da literatura revelou apenas 29 casos relatados anteriormente. Apresentamos o primeiro caso brasileiro de tal associação. Um homem de 68 anos se apresentou com dores paroxísticas insuportáveis no lado direito do pescoço, algumas vezes seguidas de síncope. Dada a suspeita de recidiva tumoral derivada de uma malignidade cervical tratada previamente, realizou-se um exame de tomografia computadorizada que evidenciou um tumor parafaríngeo direito. As dores e as síncopes foram controladas satisfatoriamente com carbamazepina e o paciente foi submetido à radioterapia paliativa.

A 74-year old man presented with recurrent attacks of altered sensorium, sometimes with abrupt falls, against the background of a long history of chronic obstructive airways disease and ischaemic heart disease. Investigations revealed evidence of significant cardiac conduction abnormalities and this led to the insertion of a permanent pacemaker. However, he continued to have recurrent 'syncopal'attacks. He was hospitalized to clarify the nature and aetiology of these attacks. Multiple stereotyped events were observed by different medical personnel, lasting up to two hours in duration. An attack was terminated by the administration of intravenous diazepam. Subsequent initiation of anti-epileptic drugs led to the complete abolition of these episodes. He has remained event-free since then ie two years. Because of multiple co-morbidities, the elderly present a greater diagnostic challenge in the evaluation of paroxysmal alterations in sensorium. It is essential that epilepsy, particularly with non-convulsive seizures, be included in the differential diagnosis whenever evaluating these patients.

Síncope é uma condição freqüentemente diagnosticada equivocadamente como crise epiléptica. No entanto, existem algumas situações nas quais a diferenciação entre ambas pode ser difícil até mesmo para alguns médicos ou especialistas bastante familiarizados com essas condições. Quatro casos de pacientes com epilepsia e/ou síncope procuraram os autores para elucidação diagnóstica. Cada caso é discutido individualmente, assim como os potenciais fatores de confusão são analisados.

El síncope es un problema común para médicos generales, neurólogos y cardiólogos. Un correcto conocimiento de la fisiopatología y de las causas más comunes es esencial para alcanzar una buena estrategia en el diagnóstico y tratamiento. Es necesario conocer las principales indicaciones de cada ayuda diagnóstica teniendo en cuenta la baja sensibilidad reportada para cada una de las mismas. Discutimos a continuación los principales conceptos del síncope dirigidos a generar la mejor aproximación de este signo en nuestros escenarios clínicos

We report a 81 years old female with a severe aortic insufficiency, treated with diuretics and antidepressants admitted due to recurrent syncopal episodes. During the first syncopal episode, an atrioventricular block was detected and an endocavitary demand pacemaker implanted. Two years later, she had a new syncope without evidences of pacemaker failure. The EKG during pacemaker rhythm showed a prolonged QT interval. During hospital monitoring, she presented a self limited polymorphic ventricular tachycardia (Torsade de pointes). Consequently, the pacemaker was programmed at a greater frequency, and the QT interval shortened from 0.73 to 0.56 sec. Thereafter, the patient no longer had tachycardia or syncopal episodes, after one year of follow up

A patient who developed syncope due to carotid sinus syndrome is described. The patient was suffering from carcinoma of the pyriform fossa for the past one year and received radiotherapy in the region of the neck for the same. Demand pacing was ineffective in alleviating syncopal episodes. The patient responded to oral administration of an anticholinergic (belladonna) and a sympathomimectic agent (orciprenaline).
