Migraine is considered to be a functional neurological disorder. In classical migraine (headache associated with prodromal visual field disturbances) and migraine accompagnée (headache associated with transient neurological symptoms), disturbances of cerebral blood flow and amine metabolism are thought to be pathogenetic factors. However, conventional methods of neuroimaging (CAT, NMR) usually do not yield any pathological findings in patients. Since 123I-iodoamphetamine (123I-IMP) crosses the intact blood brain barrier, 123I-IMP-SPECT is used for the assessment of cerebral perfusion in various neurological diseases, including functional disorders. 123I-IMP-SPECT was performed on 5 patients with classical migraine and 18 patients with migraine accompagnée. At the time of investigation, all patients were symptom-free. Cerebral blood flow was decreased in all patients with migraine accompagnée, and often corresponded to the site of headache as well as to the topography of transient neurological symptoms. This reduction was most obvious in a patient with persisting neurological symptoms. Most patients with classical migraine, however, did not show any alteration of cerebral perfusion. It appears that migraine--and in particular migraine accompagnée--is characterized by a permanent alteration not only of cerebral blood flow but also of neuronal activity. Migraine attacks may occur in connection with exacerbations of preexisting metabolic alterations. 相似文献

A 37-year old man developed an ipsilateral headache which fulfilled the criteria for cluster headache after orbital exenteration because of traumatic lesion of the bulb. The headache could be treated successfully by drugs usually applied in the therapy of cluster headache. Six similar cases of cluster headache after orbital exenteration could be identified in the literature suggesting that the eye itself is not necessarily part of the pathogenesis of cluster headache. We hypothesize that orbital exenteration can cause cluster headache by lesions of sympathetic structures. Possibly, these mechanisms are similar to those of sympathetic reflex dystrophy (Sudeck-Leriche syndrome) causing pain of the limbs. 相似文献

Prospective proton chemical shift imaging (CSI) of the brain was performed in 30 HIV- 1-seropositive patients and 11 healthy controls. Significant (P < 0.05) reductions in the N-acetyl-L-aspartate (NAA)/total creatine (Cr), and NAA/total choline (Cho) ratios and significant increases in Cho/Cr occurred in patients with 1) AIDS-defining diagnoses; 2) <200 CD4 lymphocyte counts/microl; 3) neurological evidence for an AIDS dementia complex (ADC); 4) magnetic resonance imaging (MRI) signs of cerebral atrophy. The basal ganglia and the insula were affected to approximately the same extent and without indications of spatial variations within these areas. Reduced NAA seems to indicate progressive neuronal injury or loss due to productive HIV infection in the brain and its clinical picture ADC. Spectroscopic abnormalities were, however, also observed in neurologically normal HIV patients or those with normal MRI results. Proton CSI may therefore serve as an early quantitative marker of central nervous system involvement in AIDS. 相似文献

HIV infection can be associated with different types of arthropathies which are often underdiagnosed. We present the case of a 52 year old HIV positive man on highly active antiretroviral therapy including indinavir who developed an acute painful oligoarthritis. We present this case on HIV associated arthritis and include a review on other HIV specific types of arthritis (acute symmetric arthritis and painful articular syndrome) which are assumed as entities exclusively apparent in HIV patients. The pathophysiology of arthritis in HIV infected patients is not yet completely understood but a direct role of the HIV on the initiation of synovitis is suspected in some of them. Additionally, there is evidence that antiretroviral drugs, in particular the protease inhibitor indinavir, can lead to arthritic complications as well. 相似文献

The case of a 65-year-old male migraine patient with spontaneous internal carotid artery dissection is presented. He had been abusing ergotamine compounds for several years on at least 15 days per month. A possible association between arterial dissection and ergotamine abuse is discussed. 相似文献

BACKGROUND: During the course of HIV infection, the majority of patients develop opportunistic cerebral neuro-manifestations. If conventional diagnostic tools are not sufficient, a stereotactic biopsy is often necessary. PATIENTS AND METHODS: In order to evaluate the correctness of the clinical diagnosis of cerebral neuro-manifestations in HIV-infected patients, we compared the results of cerebral biopsy or autopsy with the previous clinical diagnosis. A total of 19 biopsies and 49 autopsies could be analyzed. RESULTS: Except for HIV-associated encephalopathy, we detected a very high conformity between the clinical and the neuropathological diagnoses. We obtained the best sensitivity for progressive multifocal leukoencephalopathy (PML), whereas for cerebral toxoplasmosis the worst sensitivity and specificity was identified. CONCLUSION: We conclude that the diagnosis of PML can be made on clinical grounds alone, whereas the diagnosis of cerebral toxoplasmosis and lymphoma often requires a biopsy, which should be performed early. 相似文献
