[Neurosarcoidosis: Onset with involvement of multiple neurological sites].

We present the case of a healthy young woman who consulted for left peripheral facial palsy associated with fever, dry cough, dyspnea, and asthenia of two weeks' evolution. Physical examination revealed hypoesthesia in left T6 to T12 dermatomes and bilateral galactorrhea. In the laboratory, she presented negative viral serology, elevated erythrocyte sedimentation rate, antinuclear antibody titers, prolactin and thyroid-stimulating hormone, with positive antiperoxidase antibodies.

Exposure to endogenous and exogenous sex hormones and reproductive history influence prognosis in women with ALS.

Introduction/aims: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with a higher incidence in men suggesting an influence of sex steroids. Our objective was to investigate past exposure to endogenous and synthetic steroids in female ALS patients and controls.

Methods: We administered a questionnaire to 158 postmenopausal women (75 ALS patients and 83 controls).

Electrodiagnosis of Guillain-Barre syndrome in the International GBS Outcome Study: Differences in methods and reference values.

Objective: To describe the heterogeneity of electrodiagnostic (EDx) studies in Guillain-Barré syndrome (GBS) patients collected as part of the International GBS Outcome Study (IGOS).

Methods: Prospectively collected clinical and EDx data were available in 957 IGOS patients from 115 centers. Only the first EDx study was included in the current analysis.

[Argentine consensus on late-onset Pompe's disease].

Pompe's disease (PD) is an infrequent metabolic autosomic recessive disorder produced by the lack or deficiency of the acid alpha-glucosidase lysosomal enzyme in tissues of involved individuals. Delayed-onset PD is considered whenever symptoms onset start after one year of age. We present an update of the recommendations for the management of delayed-onset PD, taking as reference the guidelines from the Argentine Consensus for diagnosis, treatment and follow-up of PD published in 2013.

Immune-mediated rippling muscle disease and myasthenia gravis.

Cases of acquired rippling muscle disease in association with myasthenia gravis have been reported. We present three patients with iRMD (immune-mediated rippling muscle disease) and AChR-antibody positive myasthenia gravis. None of them had thymus pathology.

[Sensory neuronopathy. Its recognition and early treatment].

Sensory neuronopathies or ganglionopathies, or dorsal root ganglion disorders, represent a subgroup of peripheral nervous system diseases, frequently associated with dysinmune or neoplastic disorders and with toxic agents. A degeneration of both central and peripheral sensory proyections is present. Patients typically show early ataxia, loss of deep tendon reflexes and positive sensory symptoms present both in proximal and distal sites of the body.
