1/17. Migraine-associated vomiting and asystole in a child.A variety of symptoms that accompany migraine in the child and adult are mediated by the autonomic nervous system. Significant effects on cardiac rhythm are uncommon, but can be life threatening. We describe a 3-year-old girl in whom migraine-associated vomiting precipitated cardiac asystole which was effectively treated with a cardiac pacemaker.- - - - - - - - - - ranking = 1keywords = nervous system (Clic here for more details about this article) |
2/17. Neurobrucellosis.brucellosis, which is endemic in saudi arabia, can present as a disease with multisystem involvement. Occasionally the organisms invade the central nervous system producing varied neurological manifestations. Often the clinical diagnosis of neurobrucellosis is not straight forward and is obscure. Certain criteria have to be fulfilled for the definitive diagnosis of neurobrucellosis. We report 2 cases of neurobrucellosis which were encountered for the first time during the past 10 years at this hospital.- - - - - - - - - - ranking = 2.900816586983keywords = central nervous system, nervous system (Clic here for more details about this article) |
3/17. Cerebral vein thrombosis in Behcet's disease.Behcet's disease is a chronic, relapsing multisystem disorder, and nervous system involvement is one of the serious manifestations. Neuro-Behcet is rarely reported in children and may present with a wide variety of symptoms because the entire neuraxis may be affected. A case of cerebral vein thrombosis secondary to Behcet's disease is presented. The patient has recovered without any visual loss and had no complaints at 1-year follow-up.- - - - - - - - - - ranking = 1keywords = nervous system (Clic here for more details about this article) |
4/17. Preliminary experience with dexmedetomidine in the treatment of cyclic vomiting syndrome.Cyclic vomiting syndrome (CVS) is a chronic, recurrent disorder of unknown etiology characterized by episodes of nausea and vomiting lasting hours or days and separated by symptom-free intervals of weeks to months. Although several different therapeutic regimens have been suggested for CVS, there remains no standard, effective regimen. In many cases, management of vomiting episodes includes the use of potent sedatives that induce prolonged durations of sedation and sleep. dexmedetomidine is an alpha(2) adrenergic agonist with an increased specificity for the alpha(2) versus the alpha(1) receptor when compared with clonidine. Several physiologic effects have been demonstrated with dexmedetomidine including sedation, anxiolysis, analgesia, and blunting of the sympathetic nervous system. We report, for the first time, successful use of dexmedetomidine to treat CVS in 3 pediatric-aged patients. Potential mechanisms for its efficacy and future potential as a therapeutic agent for CVS are discussed.- - - - - - - - - - ranking = 1keywords = nervous system (Clic here for more details about this article) |
5/17. Panhypopituitarism as an initial manifestation of primary central nervous system non-Hodgkin's lymphoma.OBJECTIVE: To report an unusual case of primary central nervous system non-Hodgkin's lymphoma in which the initial manifestation was panhypopituitarism. methods: We present a retrospective case review and discuss similar cases from the literature. RESULTS: A 64-year-old woman with nausea, vomiting, diarrhea, and peripheral and periorbital edema was found to have panhypopituitarism. magnetic resonance imaging showed minimal enlargement of the pituitary, and a transsphenoidal biopsy of the pituitary was nondiagnostic. Months later, abnormalities of extraocular movements developed. Repeated imaging and a second transsphe-noidal biopsy did not reveal the ultimate diagnosis. When further neurologic signs and symptoms subsequently developed, a right temporal open craniotomy was performed. It was not until this procedure, the patient's third biopsy, that the cause of her illness was discovered to be diffuse large cell lymphoma. CONCLUSION: Although idiopathic panhypopituitarism is a relatively common clinical entity, it remains a diagnosis of exclusion. The development of associated neurologic signs should prompt the clinician to initiate a new search for an underlying cause. This case underscores the protean manifestations of central nervous system lymphoma, both endocrine and neurologic, and the difficulties that may be encountered in attempts to establish a diagnosis.- - - - - - - - - - ranking = 17.404899521898keywords = central nervous system, nervous system (Clic here for more details about this article) |
6/17. heat stroke in familial dysautonomia.A 14-month-old female with familial dysautonomia was referred to the pediatric department with high fever (41.6 degrees C), watery diarrhea, and vomiting. A few hours later, signs of encephalopathy appeared. Laboratory tests revealed elevated levels of lactate dehydrogenase (3500 U/L), aspartate aminotransferase (640 U/L), alanine aminotransferase (320 U/L), and creatine kinase (28,420 U/L). The diagnosis was heat stroke. Impaired autonomic nervous system function may be another risk factor for the development of heat stroke in young children.- - - - - - - - - - ranking = 1keywords = nervous system (Clic here for more details about this article) |
7/17. Migraine headache induced recurrent atrial fibrillation: a case report.A variety of symptoms that accompany migraine are mediated by the autonomic nervous system. The autonomic nervous system has long been known to play a potentially important role in the occurrence of atrial fibrillation. Clinically significant effects on cardiac rhythm are uncommon during migraine attacks. In the present case, we report a man who experienced recurrent episodes of atrial fibrillation, which were likely secondary to the vomiting component of migraine.- - - - - - - - - - ranking = 2keywords = nervous system (Clic here for more details about this article) |
8/17. Dengue fever with papilledema: a case of dengue-3 virus infection in central nervous system.BACKGROUND AND OBJECTIVES: Neurological manifestations of dengue fever are rarely reported during acute illness and clinical presentation commonly observed is of acute encephalitis or one of the post-infectious immune mediated manifestations. We describe a case of dengue fever having mild encephalopathy and papilledema at presentation. CASE REPORT: Twenty-year-old female presented with fever, headache and vomiting. On examination she did not have classical signs of dengue fever and was found to have bilateral papilledema on fundus examination. Detailed work-up did not reveal any other cause of papilledema. diagnosis of dengue fever was established by blood IgM antibody test on day 7 of illness. Retrospective analysis of CSF (drawn on day 5 of illness) by RT-PCR assay showed a characteristic band of dengue-3 virus. papilledema was transient and subsided following symptomatic treatment. The patient recovered from acute illness and follow-up was unremarkable. CONCLUSION: Especially in dengue endemic areas, in the patients having acute febrile illness with subtle signs and symptoms suggestive of CNS involvement, dengue virus infection should also be ruled out early in the clinical course.- - - - - - - - - - ranking = 11.603266347932keywords = central nervous system, nervous system (Clic here for more details about this article) |
9/17. carbamazepine-responsive paroxysmal nausea and vomiting in a patient with meningeal carcinomatosis.In neurology, paroxysmal syndromes are well-known, eg, as manifestations of multiple sclerosis. We report a patient with meningeal carcinomatosis, who presented with therapy-refractory nausea and vomiting. The clinical suspicion of a paroxysmal syndrome prompted a trial of carbamazepine, which resulted in complete cessation of the symptoms. In cancer patients with central nervous system (CNS) involvement and therapy-refractory symptoms with sudden onset, carbamazepine treatment should be considered.- - - - - - - - - - ranking = 2.900816586983keywords = central nervous system, nervous system (Clic here for more details about this article) |
10/17. Intracranial tumors. vomiting as a presenting sign. A gastroenterologist's perspective.vomiting is seen as a symptom in patients with brain tumors, but it rarely leads to the diagnosis in the absence of a recognized neurologic deficit. Five patients were referred to a pediatric gastroenterologist for outpatient evaluation of persistent vomiting and were subsequently found to have an intracranial mass lesion. The paucity of neurologic findings and the absence of headaches in most of these patients caused the referring physicians to focus on the gastrointestinal tract and not the central nervous system as the cause of the patients' vomiting. The pathophysiology of vomiting and evaluation of these patients is discussed; recognizable patterns of vomiting in these patients are described.- - - - - - - - - - ranking = 2.900816586983keywords = central nervous system, nervous system (Clic here for more details about this article) |
