1/5. Triptans in the treatment of basilar migraine and migraine with prolonged aura.OBJECTIVE: To report on the use of triptans in migraine with prominent neurologic symptoms. BACKGROUND: As stated in their package inserts, the triptans are contraindicated in patients with basilar or familial hemiplegic migraine, and physicians are reluctant to prescribe these drugs to other patients with prominent or prolonged aura. methods: We evaluated 13 patients with basilar migraine, familial hemiplegic migraine, or migraine with prominent or prolonged aura who had received triptans. RESULTS: Excellent; no adverse events. CONCLUSION: The contraindication of triptans in basilar migraine should be reconsidered. Similarly, prominent or prolonged aura may not represent a reasonable contraindication to triptan therapy.- - - - - - - - - - ranking = 1keywords = cell (Clic here for more details about this article) |
2/5. Reversible, strokelike migraine attacks in patients with previous radiation therapy.We report 2 adults with a past history of radiation therapy to the head for malignancy (one with primary B-cell lymphoma confined to the skull and the other with multiple hemangioendotheliomas) who developed episodes consistent with migraine with and without aura. In addition to more typical migraine attacks and beginning many years after their radiation therapy, both patients have experienced infrequent, stereotyped, prolonged, reversible neurologic deficits associated with headache, occasional seizures, and striking, transient, cortical gadolinium enhancement of the posterior cerebral gyri on MRI. Interictal MRI brain scans show stable abnormalities consistent with the patients' previous radiation therapy. The neurologic deficits often progressed over a few days, sometimes lasted weeks, and completely resolved. Electroencephalograms did not show epileptiform activity. Thorough investigation showed no residual or recurrent tumor and no recognized cause for the patients' attacks. We postulate a causal relationship between the patients' remote radiation therapy and their prolonged, strokelike migraine attacks. radiation-induced vascular changes could provoke the episodes, with or without an underlying migraine diathesis. Recognition of this syndrome can help avoid invasive testing.- - - - - - - - - - ranking = 1keywords = cell (Clic here for more details about this article) |
3/5. Familial hemiplegic migraine, neuropsychiatric symptoms, and erdheim-chester disease.We report the occurrence of unilateral cerebral hemisphere edema with subsequent cortical laminar necrosis in the setting of familial hemiplegic migraine (FHM) and permanent neurologic sequelae after resolution of an attack in 1 patient. Contemporaneous with this severe attack of FHM, the patient was found to exhibit multiple systemic and neurological symptoms referable to erdheim-chester disease (a rare non-Langerhans cell histiocytosis) that was confirmed by bone biopsy. This case demonstrates the severity possible with a migrainous infarction associated with FHM. The co-occurrence of two such rare entities in 1 patient suggests a possible relationship.- - - - - - - - - - ranking = 1keywords = cell (Clic here for more details about this article) |
4/5. autopsy case of acute encephalopathy linked to familial hemiplegic migraine with cerebellar atrophy and mental retardation.A 19-year-old female patient, who had exhibited esotropia, mild cerebellar ataxia, mild mental retardation, and cerebellar atrophy on magnetic resonance images at the age of 15, developed signs of acute encephalopathy, and thereafter died of disseminated intravascular coagulation on the day of her admission. Both her mother and sister suffered from attacks of hemiplegic migraine, mild mental retardation, and cerebellar ataxia. Neuropathological examinations revealed acute changes in the widespread cerebral cortex, chronic degenerative changes in the anterior lobe of the cerebellar vermis, axonal spheroids in the Goll's nucleus, pseudo-calcinosis in the globus pallidus, and glial bundles in the cranial nerves. The most fascinating features were changes of purkinje cells, such as cactuses (asteroid bodies, dendritic expansions), somatic sprouts, and torpedoes. These changes may be characteristic of familial hemiplegic migraine with cerebellar atrophy, as well as the other metabolic diseases, such as Menkes' kinky hair disease, infantile (Tay-Sachs type) amaurotic idiocy, organic mercury intoxication, and mitochondrial encephalopathy, of which cases often exhibit such pathological changes of purkinje cells. Therefore, familial hemiplegic migraine may share some metabolic abnormalities with the diseases mentioned above.- - - - - - - - - - ranking = 2keywords = cell (Clic here for more details about this article) |
5/5. Severe episodic neurological deficits and permanent mental retardation in a child with a novel FHM2 ATP1A2 mutation.OBJECTIVE: Attacks of familial hemiplegic migraine (FHM) are usually associated with transient, completely reversible symptoms. Here, we studied the ATP1A2 FHM2 gene in a young girl with episodes of both very severe and transient neurological symptoms that were triggered by mild head trauma as well as permanent mental retardation. Her family members suffered from hemiplegic and confusional migraine attacks. methods: mutation analysis of the ATP1A2 gene was performed by direct sequencing of all exons and flanking intronic regions, using genomic dna of the proband. Functional consequences of the mutation were analyzed by cellular survival assays. RESULTS: We identified a novel G615R ATP1A2 mutation in the proband and several of her family members. Functional analysis of mutant Na,K-ATPase in cellular survival assays showed a complete loss-of-function effect. INTERPRETATION: Permanent mental retardation in children may be caused by ATP1A2 mutations.- - - - - - - - - - ranking = 2keywords = cell (Clic here for more details about this article) |
