[Obstructive sleep apnea in children. Our experience].

We expose our experience in obstructive sleep apnea syndrome (OSAS) in the pediatric population and review the literature. Forty-six nocturnal respiratory polygraphies were performed using a portable device (Eden Trace II Plus) that measures heart rate, chest wall impedance, nasal/oral airflow and oxygen saturation. Seven children have been studied before and six weeks after Adenotonsillectomy. All this children experienced an immediate and important improvement of their obstructive symptoms. After Adenotonsillectomy the number of obstructive sleep apneas disminished up to 87.25% and the number of hypoapneas disminished up to 73.3. The arterial oxygen saturation during the night normalized in the seven patients. The initial treatment of OSAS in children should be the Adenotonsillectomy, although the diagnostic criteria of OSAS in children have to be defined more precisely in the future.

Primary localized nasopharyngeal amyloidosis. A case report.

Primary localized amyloidosis of the nasopharynx is a rare disease. We present the case of a 13-year-old girl, to our knowledge only the second pediatric case reported in the literature. Symptoms were nasal obstruction and bleeding from the oral cavity. Physical examination revealed a mass in the nasopharynx and left side of the soft palate. The diagnosis was made by biopsy and histopathologic study of the surgical specimen. Immunohistochemical study revealed amyloid light chains (AL). The main treatment was surgical. At follow-up 9 months later, no recurrence had developed. While rare, localized amyloidosis should be considered in the differential diagnosis of nasal obstruction, epistaxis and glue ear, and must be recognized and understood by the otolaryngologist to allow appropriate diagnostic and therapeutic planning.

[Intranasal encephalocele].

We present a case of an intranasal encephalocele in a 6-year old girl, that appears as an intranasal mass with CSF rhinorrhea. The surgical treatment is described, specially the extracranial step through a paralateronasal via. The embryogenesis, classification, diagnosis and management of these rare congenital lesions are discussed.

Association of spontaneous anterior fossa CSF rhinorrhea and congenital perilymphatic fistula in a patient with recurrent meningitis.

A case of recurrent meningitis associated with spontaneous cerebrospinal fluid (CSF) rhinorrhea and left sensorineural hearing loss in a 4-year-old boy was found to be due to simultaneous congenital defects. High resolution CT examination clearly showed an anterior fossa defect and an inner ear malformation, including demineralization in the region of the footplate of the stapes, and thus provided clear guidance for the surgeon.

[Intralesional treatment of cutaneous leishmaniasis: a report of two cases].

Two clinical cases of cutaneous leishmaniasis of the outer ear in children are reported. The patients were treated successfully with a single intralesional injection of N-methylglucamine antimonate (Glucantime). Aetiopathogenesis, epidemiology, clinical manifestations, diagnosis, and treatment of cutaneous leishmaniasis are discussed.

[Cochlear assessment before cochlear implantation by computer tomography with a modified Stenvers projection].

In the study protocol of candidates for cochlear implantation, the patency of the cochlea should be assessed. Therefore we systematically add the Stenvers modified projection to the routine coronal and axial sections which permits the visualization in a single sation of practically all the coils of the cochlea. This projection also is useful in postoperative controls, to confirm the correct intracochlear position of the electrode.
