OBJECTIVE We decided to review the different disorders which may affect the paranasal sinuses in the course of the acquired immuno-deficiency syndrome, and the most suitable treatment for them. DEVELOPMENT Involvement of the paranasal sinuses is not particularly common in the acquired immuno-deficiency syndrome. The commonest disorder is sinusitis. Also(More)
INTRODUCTION AND GOALS We have studied the relationship between the minimum stapedial reflex thresholds induced by means of the intra-operative stimulation of the cochlear implant and the post-operative thresholds of highest auditory comfort level. METHODS We have assessed the maximum auditory comfort at the end of the first and second quarters following(More)
We used acoustic rhinometry to evaluate the surgical results of septoplasty in patients with nasal respiratory insufficiency caused by morphological abnormalities of the nasal septum. Acoustic rhinometry is a relatively new exploration method for the nasal cavity that yields objective spatial measurements. These measurements are the cross sections and(More)
Sinonasal undifferentiated carcinoma (SNUC) is an infrequent tumor described by Frierson et al. in 1986. Since its initial description, fewer than 100 patients have been reported. We present a case of a SNUC invading the orbit in a 57-year-old woman, for which the findings are documented by CT scan, light and electron microscopy.
We study the range of the Laplace transform on convolution Banach algebras T (α)(tα), α > 0, defined by fractional derivation. We introduce Banach algebras A 0 (C ) of holomorphic functions in the right hand half-plane which are defined using complex fractional derivation along rays leaving the origin. We prove that the range of the Laplace transform on T(More)
A 38-year-old man, parenteral drug user affected by vertebral tuberculosis with involvement of the first, second and third cervical vertebrae associated with a cold retropharyngeal abscess is presented. Treatment and main clinical and histopathologic features of this very unusual location of tuberculosis are discussed.
Cochlear implants are, actually, one of the major advances in the treatment for profound deafness. His use is, already, a routine in the daily practice of our specialty. Due to its special aspects, cochlear implants have to be done following a protocol that organizes and coordinates the different aspects of the diagnoses and treatment of profound deafness,(More)
The patient was a 50-year-old alcoholic man with a left palatine tonsillar ulcer. Histopathological and bacteriological studies established the diagnosis of tonsillar tuberculosis with asymptomatic advanced pulmonary tuberculosis and multiple cerebral supra- and infratentorial tuberculomas previously unnoticed.
