1/118. Postpartum cerebral angiopathy associated with the administration of sumatriptan and dihydroergotamine--a case report.

    Cerebral angiopathy of the postpartum period is a rare entity, sometimes promoted by vasoconstrictives drug prescription. Its clinical presentation includes headaches, seizures and focal neurological deficits, which develop shortly after a normal pregnancy. The diagnosis is based on clinical findings and angiography, showing multiple narrowing of the intracranial cerebral arteries. This neurological feature is reversible and the clinical outcome is good. We report a case of benign cerebral angiopathy in a 20-year-old woman in the postpartum period, occurring after administration of sumatriptan and ergot derivates.

2/118. Dopaminergic dysfunction in midbrain dystonia: anatomoclinical study using 3-dimensional magnetic resonance imaging and fluorodopa F 18 positron emission tomography.

    OBJECTIVE: To determine the role of damage to neuronal systems, especially the dopaminergic system, in patients with symptomatic dystonia and mesencephalic lesions. DESIGN: Stereotaxic magnetic resonance imaging analysis and positron emission tomography after the administration of fluorodopa F 18. patients: Of a group of 48 patients with unilateral dystonia following a stroke, 7 patients with a well-defined midbrain lesion were selected. RESULTS: All patients had unilateral dystonic posture of an upper extremity and cerebellar dysmetria or hypotonia. Cerebellar tremor was present in 1 patient. Two patients had resting and postural tremor, which showed a marked improvement with treatment with levodopa. In patients with dystonia only, dopaminergic lesions were mostly confined to the ventromesial mesencephalon and red nucleus area, including the substantia nigra and nigrostriatal and cerebellothalamic fibers. dystonia was severe and did not resolve with time in patients with lesions involving the nigrostriatal pathway, and the degree of dopaminergic denervation revealed by positron emission tomography was correlated with the severity of dystonia. In patients with resting and postural tremor, lesions of the dopaminergic structures were larger and located more laterally and dorsally in the pars compacta, the perirubral and retrorubral areas, and extending to the central tegmental tract. CONCLUSIONS: Dopaminergic dysfunction plays a role in the occurrence and severity of midbrain dystonia, and additional lesions to dopaminergic neurons in the perirubral and retrorubral areas result in tremor that responds to levodopa treatment.

3/118. Primarily chronic and cerebrovascular course of lyme neuroborreliosis: case reports and literature review.

    As part of an ongoing study aiming to define the clinical spectrum of neuroborreliosis in childhood, we have identified four patients with unusual clinical manifestations. Two patients suffered from a primarily chronic form of neuroborreliosis and displayed only non-specific symptoms. An 11 year old boy presented with long standing symptoms of severe weight loss and chronic headache, while the other patient had pre-existing mental and motor retardation and developed seizures and failure to thrive. Two further children who presented with acute hemiparesis as a result of cerebral ischaemic infarction had a cerebrovascular course of neuroborreliosis. One was a 15 year old girl; the other, a 5 year old boy, is to our knowledge the youngest patient described with this course of illness. Following adequate antibiotic treatment, all patients showed substantial improvement of their respective symptoms. Laboratory and magnetic resonance imaging findings as well as clinical course are discussed and the relevant literature is reviewed.

4/118. Peripheral hemodialysis shunt with intracranial venous congestion.

    BACKGROUND: Intracranial venous congestion is often caused by local venous thrombosis or brain arteriovenous fistulas. Hemodialysis shunts are known to cause venous enlargement in the arm or chest but have not been related to intracranial vascular pathology. Case Description- A 59-year-old woman who presented with increasing headache, gait instability, and memory loss was a renal transplant recipient who still carried a left upper arm shunt. Cranial CT scan showed enlarged veins in the posterior fossa with incipient hydrocephalus. Extracranial duplex sonography revealed reversed flow in the left internal jugular vein, which normalized on cuff inflation around the shunt-carrying arm. The reversed flow, intracranial venous congestion, and neurological status improved after surgical shunt ligation. CONCLUSIONS: To our knowledge, this is the first case description of an intracranial venous outflow obstruction caused by a peripheral arteriovenous shunt.

5/118. Cerebral and coronary gas embolism from the inhalation of pressurized helium.

    OBJECTIVE: inhalation of helium, which produces a change in the voice, is frequently used among young rock singers to improve their performance. DESIGN: A case report. SETTINGS: Adult medical intensive care unit in a university hospital. PATIENT: A 23-yr-old singer, who accidentally inhaled helium from a high pressurized tank without pressure reduction, presented with transient loss of consciousness and chest pain. INTERVENTIONS: Electrocardiogram, chest radiograph, biochemical and toxicological analyses, echocardiography, coronary angiography were performed. MEASUREMENTS AND MAIN RESULTS: At admission, the patient slowly regained consciousness. An electrocardiogram showed significant ST elevations in leads I, aVL, and V4-V6. The chest radiograph was consistent with pulmonary congestion and pneumomediastinum. The echocardiogram showed normal sized heart chambers with hypokinesis of the left ventricular lateral wall. ethanol and urine cannabinoids were present in low concentrations, but no presence of opiates, methadone, cocaine, or amphetamines was documented. troponin t was positive. Elevation of ST segments gradually disappeared within 30 mins, the drowsiness within 10 hrs, and the thoracic pain within 24 hrs. coronary angiography showed normal coronary arteries. The patient was discharged on day 3 without any symptoms and with normal electrocardiogram and chest radiograph. CONCLUSION: Accidental inhalation of helium under high pressure can cause symptomatic cerebral and coronary artery gas embolism.

6/118. COX-2 inhibitor for the treatment of idiopathic stabbing headache secondary to cerebrovascular diseases.

    The idiopathic stabbing headache (ISH) is characterized by a stabbing pain of short duration, variable localization and an errant evolution pattern. As its biological mechanisms are unknown and the treatment options are little effective, this disorder shows a strong impact on the patient's life. Two females and one male, aged 76, 66 and 72 years, respectively, started presenting ISH within 20 days after the onset of a stroke. All the patients were treated for the ISH with celecoxib, a COX-2 specific inhibitor, with full recovery from ISH up to 6 days after it was first administered. The interruption of the drug 60 days after the treatment with celecoxib induced again the appearance of algic symptoms in two patients. We concluded that cerebrovascular diseases (CD) can lead to ISH and that the COX-2 inhibitor can be an effective prophylactic drug for ISH after CD.

7/118. Takayasu's arteritis presented with subarachnoid hemorrhage: report of two cases.

    Takayasu's arteritis is a chronic inflammatory disease that produces a narrowing of the aorta and its major branches. fibrosis and thickening of the arterial wall often occur in later stages, resulting in a cerebrovascular accident. The authors report two young women patients who presented with subarachnoid hemorrhage (SAH) and occlusive cerebrovasular disease associated with Takayasu's arteritis. Both patients had sudden headache and hemiparesis. physical examination showed weak radial pulse, carotid bruit, and asymmetrical blood pressure. Erythrocyte sedimentation rate (ESR) was elevated in both patients. SAH was confirmed by brain computerized tomography (CT) or lumbar puncture. Occlusive cerebrovascular disease was diagnosed by brain magnetic resonance imaging (MRI), brain magnetic resonance angiography (MRA), and cerebral angiography. The findings of aortography and cerebral angiography were compatible with Takayasu's arteritis, but intracranial aneurysm was not found in either patient.

8/118. Cerebrovascular cases.

    Five cases are presented illustrating some of the investigative and therapeutic dilemmas faced when treating patients with cerebrovascular disease in the outpatient clinic. The results of some recent major randomized controlled trials are applied to assist the decision-making process for individual patients. The investigation and management of patients with minor stroke or transient ischemic attack, and symptomatic or asymptomatic carotid stenosis are discussed. Issues raised include the role of angiography versus noninvasive imaging, carotid endarterectomy versus carotid stenting, and how to apply new evidence regarding antihypertensive and lipid-lowering therapy to patient management. The role of thrombolysis for acute stroke is discussed, and the work-up of a patient with attacks of dizziness and a patient with atypical headache are also presented.

9/118. Hemiparesis in hiv infection. rehabilitation approach.

    persons with acquired immunodeficiency syndrome (AIDS) and human immunodeficiency virus (hiv) infection demonstrate a wide array of central nervous system impairments and may be at a significantly increased risk for cerebrovascular disease. Cerebrovascular disease can be the first manifestation of hiv infection and may be associated with a treatable etiology. Anticipating more referrals for hiv-related physical disability, we detail the rehabilitation management of three persons with hiv infection and hemiparesis. Onset of hemiparesis ranged from just before to 24 months after an AIDS-defining illness. No specific underlying etiology was identified in two of three patients, consistent with previous observations. rehabilitation interventions included lower and upper extremity orthoses, assistive devices to aid gait and activities of daily living, therapeutic exercise and use of antispasticity medication. All patients made at least mild, temporary gains in functional status. survival ranged from 3 to >6 months from initial contact with rehabilitation services. Neurologic and nonneurologic considerations in the rehabilitation of persons with hiv infection are discussed. We conclude that selected individuals with hiv infection and hemiparesis can benefit from rehabilitation intervention. hiv infection should be considered in any young adult presenting with stroke.

10/118. Headaches due to vascular disorders.

    The association between stroke and headache is complex, ranging from highly nonspecific, wherein headache is largely irrelevant to diagnosis and therapeutic management, to highly specific and even causative. In short, acute headache may accompany the acute stroke process, chronically complicate stroke, or, in rare instances, serve as the primary cause of stroke. With the first instance, the incidence of acute headache is highly dependent on the stroke sub-type and etiology. In this article, the headaches accompanying or causing acute stroke are addressed in some detail.
