We carried out a prospective study of 530 patients older than 14 years of age with brucellosis. We describe the incidence and clinical features of the focal forms of the disease, analyzing some of the possible factors associated with their appearance. One hundred sixty-nine patients (31.9%) had a focal form or complication. Osteoarticular complications were(More)
We studied 7 patients with an acute motor axonal Guillain-Barré syndrome (GBS), manifested 5 to 15 days after parenteral injection of a commercial ganglioside preparation given for nonspecific pain syndromes. The serum IgG and IgM antibody response to ganglioside was studied serially and the recognition of epitopes on the peripheral nerves and motor(More)
A multicentre prospective study of 593 patients with brucellosis, of whom 58 (9.7%) had spondylitis, was performed in order to evaluate the possible clinical, radiological and evolutionary differences in the different segments of the spinal column. Five of the patients with cervical spondylitis (71%) had compression of the medulla or roots, versus just two(More)
BACKGROUND Toxic epidermal necrolysis is a severe reaction with skin involvement induced by different drugs and other agents. The mechanisms implicated in the induction of the reaction are poorly understood. OBJECTIVE Our purpose was to study the involvement of T lymphocytes and other immunocompetent cells in the peripheral blood, blister fluid, and(More)
BACKGROUND A 46-year-old woman presented to a local hospital with acute respiratory failure and a 2-year progressive history of fatigue, personality changes, increased sweating, dysphagia with substantial weight loss, dysarthria, and intermittent ptosis and diplopia. Neurological examination showed facial weakness, lingual atrophy and bulbar palsy, which(More)
BACKGROUND The cross-reactivity between penicillins and cephalosporins can be influenced by different factors, which are not all well known. The chemical structure of the side chain may contribute to the cross-reactivity. OBJECTIVE The study was carried out in allergic subjects who are selectively responsive to amoxicillin to determine allergenic(More)
BACKGROUND Penicillin is no longer the most commonly prescribed beta-lactam, and the pattern of reactions has changed. We studied the diagnostic value of skin testing in penicillin-allergic subjects from a population where benzylpenicillin is not now the most frequently used beta-lactam. METHODS Patients with a history of immediate allergic reactions to(More)
BACKGROUND Systemic allergic reactions to Hymenoptera venom occur in a percentage that varies from 0.4 to 3.3%. Epidemiological studies indicate that from 15 to 25% of the general population can be sensitized to different Hymenoptera venom as well as the fact that the degree of exposure may be related to the prevalence found in those studies. OBJECTIVE(More)
The PM/Scl antigen from mammalian cells has been characterized as a nucleolar and nucleoplasmic molecular complex containing at least 16 polypeptides ranging in molecular weight from 110 to 20 kD. Of these polypeptides, we have found those of 68, 39 and 20 kD to be in a phosphorilated form. Whereas the entire complex was precipitated by all the anti-PM/Scl(More)
Female guinea pigs had intraventricular injections of either IgG from a patient with paraneoplastic cerebellar degeneration (PCD) and anti-Purkinje cell antibodies (anti-Yo IgG) or control IgG. In animals that received a single injection of control or anti-Yo IgG and were killed at different time intervals, IgG immunoreactivity was present in the cytoplasm(More)
