OBJECTIVE To compare the efficacy of acetaminophen, ibuprofen, and prednisone in the treatment of interferon beta-1a (IFNbeta-1a) flu-like syndrome (FLS). METHODS Patients with relapsing-remitting multiple sclerosis initiating treatment with IM IFNbeta-1a were randomized in a multicenter, randomized, double-blind, controlled trial to receive acetaminophen(More)
A new analytical method is proposed to determine more than 40 multiclass pesticides in different kinds of processed (whole, skimmed and powdered) and unprocessed (goat and human) milk samples using solid-phase microextraction (SPME). A comparative study between headspace (HS) and direct immersion (DI) was carried out. The effect of milk dilution and the use(More)
Water quality assessment in the Aznalcollar area was attempted using multivariate methods based on heavy metal concentrations in red swamp crayfish (Procamburus clarkii). Trace levels of four heavy metals, copper (Cu), zinc (Zn), cadmium (Cd) and lead (Pb), were detected in crayfish from eleven different stations. Principal component analysis (PCA)(More)
A Spanish family with the DTI variant sensitive to L-Dopa is presented with three patients, 2 first cousins and an aunt being described. The dystonic beginning of the disease during infancy is of note in the former two patients as is the later initiation of parkinsonism in the third patient. Marked improvement was observed in all of the patients with L-Dopa(More)
AIMS The aims of this paper is to demonstrate the existence of neuropsychological disorders in amyotrophic lateral sclerosis (ALS) and to perform an in depth study of the cognitive functioning of the prefrontal lobes. PATIENTS AND METHODS A neuropsychological study of 14 patients with ALS was conducted using an extensive battery of tests and were compared(More)
A selective and reliable extraction procedure was developed and validated to determine multiclass pesticide residues in lyophilized agricultural plants by low-pressure gas chromatography coupled with tandem mass spectrometry. The method is based on a rapid and simple extraction of the lyophilized sample with dichloromethane. The results were compared with(More)
