Placebo-controlled comparison of effervescent acetylsalicylic acid, sumatriptan and ibuprofen in the treatment of migraine attacks.

Acetylsalicylic acid (ASA) in combination with metoclopramide has been frequently used in clinical trials in the acute treatment of migraine attacks. Recently the efficacy of a new high buffered formulation of 1000 mg effervescent ASA without metoclopramide compared to placebo has been shown. To further confirm the efficacy of this new formulation in comparison with a triptan and a nonsteroidal anti-inflammatory drug (ibuprofen) a three-fold crossover, double-blind, randomized trial with 312 patients was conducted in Germany, Italy and Spain.

[Spanish contribution to the clinical development of eletriptan: an analysis of controlled studies].

Introduction: Eletriptan is a recently marketed second-generation triptan with a potent agonist activity on 5-HT1B/ 1D receptors. Our aim has been to analyze the specific results from the Spanish participation in phase IIIa and IIIb clinical trials vs placebo and compare them with the results obtained in the global clinical development of eletriptan.

Patients And Methods: Analysis of the results obtained in 40 centers in Spain (358 patients) vs global sample 4,677 patients) for the first migraine attack in 6 controlled clinical trials with eletriptan 40 mg, eletriptan 80 mg and placebo.

Efficacy and safety of metamizol vs. acetylsalicylic acid in patients with moderate episodic tension-type headache: a randomized, double-blind, placebo- and active-controlled, multicentre study.

We assessed the efficacy and safety of oral single doses of 0.5 and 1 g metamizol vs. 1 g acetylsalicylic acid (ASA) in 417 patients with moderate episodic tension-type headache included in a randomized, double-blind, placebo- and active-controlled, parallel, multicentre trial.

Comparative efficacy and safety of calcium carbasalate plus metoclopramide versus ergotamine tartrate plus caffeine in the treatment of acute migraine attacks.

This randomized, double-blind, double-dummy, multicenter, parallel-group study aimed at comparing the efficacy and safety of calcium carbasalate (equivalent to 900 mg aspirin) plus metoclopramide 10 mg (CM) with ergotamine tartrate 1 mg plus caffeine 100 mg (EC) administered in the treatment of 2 acute migraine attacks. A total of 296 patients fulfilling the International Headache Society diagnostic criteria for migraine were enrolled. In total, one or two migraine attacks were treated in 268 and 235 patients, respectively.

Early combination of bromocriptine and levodopa in Parkinson's disease: a prospective randomized study of two parallel groups over a total follow-up period of 44 months including an initial 8-month double-blind stage.

To determine if the combination of levodopa (LD) plus bromocriptine (Br) in the early stages of Parkinson's disease (PD) permits reduction of LD dosage and consequently results in fewer motor fluctuations and dyskinesias, a double-blind, multicenter prospective study in 50 PD patients who had responded favorably to LD while under treatment with that drug for < or = 6 months was undertaken. Patients were randomized into two parallel groups (LD alone and LD plus Br). During the first placebo-controlled stage of the study lasting 8 months, association of a fixed dose of Br (15 mg/day) in the LD regimen did not allow a significant reduction in the daily LD dose.

[Cognitive functions in agenesis of the corpus callosum].

Four patients with agenesis of the corpus callosum diagnosed through neuroradiologic tests has been studied, from the upper cerebral functions point of view. Three had consulted because of seizure, and the other because of cerebellar hemorrhage. Multiple fields of the cognitive functions were examined and the presence of an interhemispheric disconnection syndrome was investigated.

Continuous muscle fiber activity, peripheral neuropathy, and thymoma.

Two patients, one of them with myasthenia gravis, presented symptoms of continuous muscle fiber activity syndrome before discovery of a thymoma. Peripheral neuropathy was present in both patients, with axonal and demyelinating lesions in sural nerve biopsy. The syndrome remained unchanged or worse after thymectomy.

Central pontine myelinolysis following correction of hyponatremia: MRI diagnosis.

A 37-year-old woman with hepatic failure developed a locked-in syndrome after correction of a severe symptomatic hyponatremia. Magnetic resonance imaging showed a lesion involving the basis pontis and extending into the midbrain, consistent with central pontine myelinolysis. In this patient the rate of correction of hyponatremia was within the range considered sure by several authors, but factors such as hepatic encephalopathy, a single generalized seizure and correction of hyponatremia in 42 h with a change in serum sodium concentration of 34 mmol/l were present, and they could have been etiologically relevant.

Bilateral facial paralysis secondary to trichinosis.

Myocarditis and neurological disorders are the most serious complication of human infestation by Trichinella spiralis. On occasion, the unawareness of clinical manifestations, the form of presentation and the association of uncustomary neurological symptoms impedes the diagnosis of trichinosis. We report a case of trichinosis with peripheral facial diplegia, meningeal disorder and EKG alteration, with no prior intestinal symptomology.
