OBJECTIVES To study the relationship between age and postural control in patients with benign paroxysmal positional vertigo. MATERIAL AND METHODS Prospective study performed in 65 diagnosed patients with benign paroxysmal positional vertigo (BPPV) in any of its variants. The results of the Sensory Organization Test are compared with their equivalent in a(More)
INTRODUCTION AND OBJECTIVES The power spectral density can be used to find a hidden behaviour in a physical system. We studied postural behaviour in a healthy population, by means of power spectral density, and compared it with a situation of complete immobility. METHODS A group of healthy volunteers carried out the modified Clinical Test for Sensory(More)
One percent of excised thyroglossal duct remnants exhibit histologic malignancy, a thyroid papillary carcinoma in 80% of the cases. The prognosis is excellent except for anaplastic types. We report the case of a 44-year-old woman with primitive thyroid papillary carcinoma diagnosed histologically as thyroglossal cyst. Its unusual aggressiveness produced(More)
A group of 253 patients with laryngeal carcinoma was treated by endoscopic laser-CO2 surgery, 50 of them presented a supraglottic localization. The follow up period ranged from 1 to 10 years. From the analysis of different parameters (age, site, stage, histopathology, etc) it could be concluded that survival and free-symptoms-time rates in patients treated(More)
OBJECTIVE To study the relationship between age and posturography in patients with benign positional paroxysmal vertigo. MATERIAL AND METHODS Prospective study performed in 65 patients with benign positional paroxysmal vertigo (BPPV) in any variant. Sensory Organization Test outcomes were recorded and compared with their equivalents in a control group by(More)
The recording of auditory brain stem potentials (ABR) with bimastoid leads and bilateral stimulation makes it possible to evaluate relative cochlear function and the type of hearing loss. The theoretical background for this technique and the results obtained in patients with disease of the internal-middle ear, cochlea, and auditory nerve are discussed.
"Malignant centrofacial granulomatosis" is an unusual but devastating spectrum of lymphoproliferative disorders that is now thought to include several entitites, such as polymorphic reticulosis or peripheral T-cell lymphoma. Characteristically there are destructive centrofacial lesions which often produce difficulties for the diagnostic to the clinician and(More)
In 1905 Barany analyzed the nystagmus that appears during the irrigation of the ear with cold and hot water, justifying the phenomenon due to convectives currents in the horizontal semicircular canal. This hypothesis has been widely accepted until doubt was casted on it by the experiences carried out in the Skylab. Of the various mechanisms that could be(More)
