Acute myocardial infarction after sumatriptan administration for cluster headache.

The pain of cluster headache attacks is severe, excruciating and selectively responsive to subcutaneous sumatriptan. Serious cardiovascular events attributed to sumatriptan are extremely rare and have most often been reported in patients at significant cardiovascular risk, or in overt cardiovascular disease. They also have occurred, however, in patients without evidence of cardiovascular disease. We describe a 42-year-old man with episodic cluster headache without history of coronary artery disease who was admitted to our coronary care unit for acute myocardial infarction after 3 h of subcutaneous injection of sumatriptan. During hospitalisation cluster headache attacks were successfully treated with e.v. indomethacin.

The Stroke in Italy and Related Impact on Outcome (SIRIO) study: design and baseline data.

The SIRIO study collected detailed information on the stroke care of patients treated in neurological departments in Italy. This report refers to the baseline profile of patients. Each centre recorded the incident cases of ischaemic and haemorrhagic stroke, excluding SAH, for 1-4 months. Baseline data include demographics, risk factors, comorbidities, pre-event medications, social conditions, NIHSS and Rankin scale on entry, Barthel Index pre-event, diagnostic tests and treatments applied on entry. Overall, 3018 patients (56.7% men; mean age 72.1+/-12.2 years) with ischaemic (85.3%) or haemorrhagic stroke were hospitalised in 103 centres; 51% arrived by ambulance. Median time to hospital was 140 min (RIQ: 60-615). TOAST classification of the 2573 ischaemic strokes was: 29.4% large-artery atherosclerosis, 24.6% cardioembolic, 26.2% small vessels occlusion, 6.5% other determined causes and 13.3% undetermined. CT and/or MR were performed in all patients. Total Greenfield's comorbidity score was 5.4+/-3.5. Mean Barthel Index pre-event was 93+/-17; Rankin score on entry was 4-5 in 48% of the patients and 0-1 in 25%. Mean NIHSS on entry was 7.1+/-5.4; 52% of the patients had a NHISS <6 and 1% >22. SIRIO began giving the expected insights on the in-hospital management of stroke in Italy. Further information will be provided by the longitudinal phase of the study, which is in progress. Pre-event patient management and mode of reporting call for additional educational actions.

Elevated plasma homocysteine in acute stroke was not associated with severity and outcome: stronger association with small artery disease.

Homocysteine increases in the acute phase of ischaemic stroke and from the acute to the convalescent phase, suggesting that hyper-homocysteinaemia may be a consequence rather than a causal factor. Therefore we measured homocysteine plasma levels in stroke patients in order to investigate possible correlations of homocysteine with stroke severity and clinical outcome. Further we looked for eventual differences in stroke subtypes. We prospectively studied plasma homocysteine levels in acute stroke patients admitted to the stroke unit of our department. Seven hundred and seventy-five ischaemic stroke patients, 39 cerebral haemorrhages and 421 healthy control subjects have been enrolled. Stroke severity and clinical outcome were measured with the Scandinavian Stroke Scale, the Rankin Scale and the Barthel Index. Stroke severity by linear stepwise regression analysis was not an independent determinant of plasma homocysteine levels. Homocysteine was not correlated with outcome measured by the Barthel Index. Mean plasma homocysteine of both ischaemic and haemorrhagic stroke was significantly higher than controls (p<0.05). Homocysteine had an adjusted odds ratios (OR) of 4.2 (95% CI 2.77-6.54) for ischaemic stroke and of 3.69 (95% CI 1.90-7.17) for haemorrhagic stroke. Compared with the lowest quartile, the upper quartile was associated with an adjusted OR of ischaemic stroke due to small artery disease of 17.4 (95% CI 6.8-44.3). Homocysteine in the acute phase of stroke was not associated with stroke severity or outcome. Elevated plasma homocysteine in the acute phase of stroke was associated with both ischaemic and haemorrhagic stroke. Higher levels are associated with higher risk of small artery disease subtype of stroke.

Quantification of the risk of post stroke depression: the Italian multicenter observational study DESTRO.

OBJECTIVE: The Italian multicenter observational study depression in stroke (DESTRO) aimed to identify risk factors for post stroke depression (PSD) and quantify the likelihood of it arising in various categories of patients. METHOD: Mood evaluation was performed in 1064 consecutive stroke patients by means of Beck Depression Inventory and Visual Analog Mood Scale. Depressive symptoms were classified using the DSM-IV and revised WHO criteria for depression in the course of a neurological disorder. RESULTS: Post stroke depression was seen in 36% of the survivors, with dysthymia by far the predominant form (80.7%). Female sex, disability, previous cerebrovascular or depressive episodes were significantly associated with an increased risk of depression. Combinations of these factors raised the risk of PSD exponentially, from 24.3 to 89.1%. The site of the stroke did not come into the uni- or multivariate analysis. CONCLUSION: At admission, it is possible to predict the likelihood of PSD and quantify the relative risk.

Post-stroke depression: research methodology of a large multicentre observational study (DESTRO).

The heterogeneity of published data regarding post-stroke depression (PSD) prompted an Italian multicenter observational study (DESTRO), which took place in 2000-2003. The investigation involved 53 Italian neurology centers: of these, 50 treat acute patients and 3 provide rehabilitation care; 21 centres are in Northern Italy, 20 are in Central Italy, and 12 are in Southern Italy. The time schedule was articulated into three phases: registration of 6289 stroke patients; selection of 1817 cases and enrollment of 1074 patients; and follow-up for two years (1064 patients). Mood assessment was performed by evaluating depressive symptoms according to DSM IV and the Beck depression inventory (visual analog mood scale for aphasic patients). Depressed patients were also administered the Montgomery-Asberg depression rating scale. Scores were related to function (Barthel index, modified Rankin scale), cognition (MMSE), quality of life (SF-36), and clinical data. Data analysis will provide information on PSD prevalence, onset and evolution, correlation with ischemic clinical syndrome, impact on activities of daily living, cognitive level and quality of life. The few data available at the present time concern PSD prevalence in the first six months after stroke (33.6%). DESTRO is a longitudinal investigation of a large patient sample and is expected to provide insights into the relationship of PDS with the functional and clinical consequences of stroke.

Temporal profile of serum anti-inflammatory and pro-inflammatory interleukins in acute ischemic stroke patients.

The presence of an inflammatory response in the pathophysiology of acute brain ischemia is relatively well established, but less is known about the anti-inflammatory mechanisms. The aim of the present study was to evaluate part of the immune response in acute stroke patients and to analyze a possible correlation with other hematological parameters, clinical outcome, size of infarct and subtypes of strokes. We prospectively studied 42 stroke patients, without signs of infections or inflammatory diseases, at days 0, 1, 3, 7 and 14, and 39 healthy control subjects. We measured serum levels of the anti-inflammatory cytokine interleukin-10 (IL-10) and the pro-inflammatory cytokine interleukin-6 (IL-6) by ELISA method. We observed a highly inverse correlation between these two molecules in control subjects (r=-0.78, p=0.0000001), and this correlation was lost in stroke patients. Patients had significantly lowered IL-10 serum levels soon after the acute event (p=0.00005), with a slight increase at the seventh day. On the other hand, patients had increased IL-6 serum levels compared with controls after day one until day 14 (p<0.04), with a maximum increase at day 3. Interleukin-6 correlated with clinical outcome whereas interleukin-10 did not. Low levels of interleukin-10 indicate that the antiinflammatory response is down-regulated in acute stroke patients. The pro-inflammatory response begins 24 hours after the onset of acute cerebral ischemia, as indicated by the increased serum levels of interleukin-6. The physiological balance between these two molecules is altered in acute stroke patients.

Stenting of the extracranial internal carotid artery for dissecting aneurysm.

Symptomatic dissecting aneurysms of the extracranial internal carotid artery are not frequent. Medical treatment of these lesions can be ineffective and surgical options present high morbidity. We describe a case successfully treated with endovascular therapy, using a self-expanding stent. The advantages of the endovascular treatment and the rationale of the use of self-expanding stents are discussed.

Alpha-dihydroergocryptine in Parkinson's disease: a multicentre randomized double blind parallel group study.

INTRODUCTION: A multicentre randomized double-blind parallel group study was carried out on 68 patients suffering from idiopathic Parkinson's disease (PD) treated with L-dopa for at least 1 year with inadequate therapeutic responsiveness. The aim of the study was to compare the efficacy of alpha-dihydroergocryptine (alpha-DHEC) vs lisuride as an adjunct therapy to L-dopa on dyskinesias and clinical fluctuations (Unified Parkinson's Disease Rating Scale [UPDRS] part IV), on the symptoms pattern (Columbia University Rating Scale [CURS]), on disability (Northwestern University Disability Scale [NUDS]), and to evaluate the incidence of adverse events. PATIENTS AND METHODS: Thirty-two patients (18 males, 14 females with a mean age of 64.5+/-1.5 SEM) were randomized to alpha-dihydroergocryptine and 36 (16 males, 20 females with a mean age of 61.8+/-1.4) to lisuride. The treatment lasted 3 months and the dosage was increased until it reached 60 mg/day of alpha-dihydroergocryptine and 1.2 mg/day of lisuride, while the L-dopa dosage was kept constant in both groups. Per protocol and intention to treat analyses were performed on response variables. RESULTS: The adjunctive treatment with the two dopamine agonists determined a significant improvement of PD symptoms in both groups. Alpha-dihydroergocryptine showed a superior efficacy in reducing the clinical complications (P < 0.01 by ANOVA). The number of patients complaining of adverse events was 8 out of 32 (25%) for alpha-dihydroergocryptine and 24/36 (67%) for lisuride (P < 0.05). CONCLUSION: Alpha-dihydroergocryptine effect seems to be superior to that of lisuride both in terms of reduction of L-dopa therapy long term motor complications (UPDRS part IV) as well as in terms of the incidence and severity of adverse events.

Benign cough "cluster" headache.

Benign cough headache presents as a sudden bilateral, short-lasting pain precipitated by coughing. The diagnosis requires noninvasive brain-imaging so that secondary causes can be ruled out. We describe a man, 57 years of age, complaining of an atypical form of benign cough headache which shares some features with episodic cluster headache. To our knowledge, this is the first description of a link between these two types of idiopathic headache.

A casual spontaneous mutation as possible cause of the familial form of arrhythmogenic right ventricular cardiomyopathy (arrhythmogenic right ventricular dysplasia).

In a family affected by arrhythmogenic right ventricular cardiomyopathy (ARVC) the familial occurrence was investigated. All 14 members of two generations were investigated carefully, and only 2 (father and one son) members were affected. Both subjects had a massive form of the disease with relevant ventricular arrhythmias. Apart from the limitations of having investigated few subjects, this behavior suggests a genetic mutation appearing in the father and transmitted via an autosomal dominant trait.

Unilateral swelling of the lower abdominal wall. Unusual clinical manifestation of an upper lumbar disc herniation.

Circumscribed unilateral paralysis of abdominal muscles is a rare clinical feature and has previously been described in diabetic neuropathies and traumatic or non-traumatic compressive neuropathies. The paper describes a case presenting with transversus abdominis muscle paralysis and burning paraesthesia in the anterolateral aspect of the thigh caused by a lateral L2-L3 disc herniation. Abdominal echography and the EMG investigation led to the suspicion of a disc prolapse which was eventually verified by myelography completed with a CT scan. Surgery confirmed L2 root compression by a large calcified herniation in the intervertebral foramen L2-L3. The anatomical principles are recalled to explain the clinical manifestations.

Correlation between clinical and molecular features in two MELAS families.

We describe the clinical, morphological, biochemical presentation in two MELAS families, and correlate it with the distribution and proportion of mitochondrial DNA carrying the A to G transition at nt 3243. Family A was characterized by late onset MELAS in two members, CPEO in one, and mild CNS involvement in another. 20-61% of mtDNA of affected and unaffected individuals was mutated in muscle, 2-18% in blood. There was no obvious correlation between clinical picture and proportion of mutated mtDNA. In family B full MELAS syndrome appeared only in the third generation, but the mutation was also detected in muscle of asymptomatic individuals of the first and second generation. The proportion of mutated mtDNA in blood, and to a lesser extent in muscle, correlated with the severity of the clinical presentation. The MELAS mutation is consistently detected in all asymptomatic maternal relatives of MELAS patients. We conclude that different clinical presentations of mitochondrial encephalomyopathy may coexist in the same family, and correlation between clinical severity and molecular abnormality is not always recognizable. Presence of the MELAS mutation in muscle and blood is a necessary but not sufficient condition for the expression of the typical MELAS phenotype.

Single photon emission tomography findings in lacunar lesions.

99-Tc hexamethyl propylene amine oxime single photon emission tomography was performed in 18 patients showing typical lacunar hypodensities on CT scan (3 with Binswanger's disease and 3 with acute-stage lacunar syndrome). Reduced radiouptake in the site of the lacunar lesions was observed in 7 out of the 18 patients, while all of the patients with Binswanger's disease showed a bilateral reduced whithe matter uptake. Two of the three acute-stage lacunar syndrome patients showed a reduced radio uptake in the cortical areas of the hemisphere, in which the lacunar lesion was detected (diaschisis), followed by subsequent normalization and clinical improvement.

Cognitive performance and Parkinson disease: neuropsychological and CT study.

30 patients with Parkinson disease were investigated with computed tomographic (CT) scanning and neuropsychological tests. The CT data proved to be of scant interest whereas tests of intelligence, verbal and visual memory and visuomotor abilities were all informative. Parkinsonian patients with cognitive impairment seem to constitute a separate group in which akinesia and gait disturbances predominate.

Primary brain stem haemorrhages: clinico-radiological considerations on five cases observed.

Five patients with primary brain stem haemorrhage are reported, of whom four survived. One died from complications involving other organs. The diagnosis was made by computerized tomography which also allowed the temporal evolution of the lesion to be followed. The importance of haemorrhagic lesions in brain stem vascular pathology with regard to ischaemic lesions is re-evaluated.

Planned release dihydroergotamine in common migraine and "tension-vascular headache": multicentre clinical trial.

The antimigraine efficacy of dihydroergotamine methanesulphonate in the pharmaceutical form of planned release capsules has been evaluated. Forty-nine subjects were treated, 39 suffering from common migraine 10 from tension vascular headache, for a period of 90 days, with an oral dose of 15 mg twice daily. The product was found to be efficacious in 71% of the common migraine cases, while unsatisfactory or nil results were obtained in the remaining 29%. In the tension-vascular headache cases, efficacy was 40% compared to 60% unsatisfactory or nil results. Tolerance was good in 43 cases, while transient digestive disorders (nausea and vomiting) occurred in 6; in 2 cases the treatment had to be withdrawn for allergic erythema. The results demonstrate that the drug is indicated in cases of common migraine, while it does not appear to significantly influence the course of attacks of tension-vascular headache.
