Glossopharyngeal neuralgia is an uncommon condition that has rarely been described in association with syncope. We report here 2 cases of glossopharyngeal neuralgia in elderly patients. Both were male and underwent temporary pacemaker insertion to prevent syncopal episodes. We discuss the clinical and surgical treatment of glossopharyngeal neuralgia, the role of cardiac stimulation, and the possible physiopathological mechanism of the associated cardiac disturbances.
We report the case of a 42-year-old female with fatigue on exertion and palpitation consequent to the existence of isolated noncompaction of the myocardium. We discuss clinical and familial findings, diagnostic possibilities, and prognostic and therapeutical implications of this rare disorder of endomyocardial morphogenesis.During the initial phase of embryonic development, the heart is a trabecular net with a spongy myocardium. The intertrabecular spaces communicate with the cardiac chambers. As the heart develops, the myocardium condenses and the intertrabecular recesses are reduced to capillaries. Trabecular compaction is usually more complete in the left ventricle than in the right ventricle. Noncompaction of the ventricular myocardium is defined as an anomaly of endomyocardial morphogenesis, and it is believed to be an arrest in the compaction of the myocardial fibers, which meet forming an interwoven loose net during intrauterine life. Persistence of the noncompaction of the myocardium is a rare entity, usually diagnosed in the pediatric population and associated with other structural congenital malformations of the heart. It predominates in patients with congenital obstruction of the right or left ventricle outflow tract [1][2][3][4] . Isolated noncompaction of the myocardium, defined by absence of any other associated structural cardiac alteration, is an even rarer form of the entity, with only a few reports in the literature [5][6][7][8] . Isolated noncompaction of the myocardium may be identified from childhood to adulthood. Its diagnosis may be delayed because of some findings resembling other clinical entities. Both sexes may be affected and familial recurrence may occur.We report the case of a 42-year-old female with isolated noncompaction of the myocardium, describing the clinical and familial history, diagnostic possibilities, and therapeutical approach. We also review the literature about this rare disorder of endomyocardial morphogenesis. Case reportA 42-year-old female complaining of fatigue on medium exertion, chest pain, and palpitation for 10 years was referred to our service to investigate arrhythmia. She reported loosing 2 children in the first year of life, one due to sudden death at the age of 5 months and the other due to refractory heart failure in the first week of life. The anatomicopathological study of the latter child performed in another service showed a dilated left ventricle with increased and abnormal trabeculation, whose final diagnosis, at the time, was cardiomyopathy of undetermined etiology. She also reported two siblings who had sudden death during childhood, and one uncle and one cousin, who died due to refractory congestive heart failure. The physical examination was normal. The 12-lead electrocardiogram showed sinus rhythm and deviation of the axis to the right in the frontal plane without meeting the criteria of left posteroinferior divisional heart block (figura 1A). Chest X-ray was normal. The exercise test showed depression of the ST segment associated with typical...
Many anesthesiologists in Central Western Brazil do not sedate dental patients and are not confident that dentists are able to do it. Dental sedation is an issue that still needs to be clarified in this region; the respective roles of physicians and dentists need to be determined to benefit the population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
