[Oropharyngeal synovial sarcoma. Report of one case]. / Sarcoma sinovial de orofaringe. Aportacíon de un caso.

Synovial sarcoma is a malignant growth of the soft parts of young people, scarcely of the head and neck. The tumor classic is two-phase composed by epithelial and spindle cells. The AA. report a new case of synovial sarcoma located in the oropharynx and the treatment followed, and discuss as well the histology and the origin of these tumors.

[Middle ear pressure changes following adenoidectomy. Contribution to the etiopathogenic study of serous otitis media]. / Modificaciones en la presión del oído medio tras adenoidectomía. Aportación al estudio etiopatogénico de la otitis media seromucosa.

This paper deals in the pursuit done on endotympanic pressures in children operated upon adenoidectomy, a lot of them simultaneously suffering from serious otitis media. The obtained results are compared with those of healthy children, with the aim of set up the pressure changes within the middle ear due to surgery and as well the knowledge of the natural evolvement of the serious otitis. In accordance with date registered and the perusal of the Bibliography at hand, the AA. try to find out the possible influence of the adenoid hypertrophy on this type of otitis. But all without arguing the role played by other causes (split palate, neoplastic obstruction, ciliar dyskinesy, etc.). Finally a new etio-pathogenic mechanism, in order to explain the negative pressures inside the middle ear due to adenoid hyperplasty, is proposed.

[Neurinoma of the thyroid gland]. / Neurinoma de localización tiroidea.

Schwannomas are solitary neurogenic tumors that arise from cells of the neural sheat. They grow slowly and represent a proliferation of Schwann cells. Extracranial neurogenic tumors of the head and neck are uncommon. We describe a case of solitary cervical schwannoma placed in the thyroid area. And recall the histology, the nerves more frequently involved, diagnostic tests and the treatment of these nervous tumors.

[Sudden bilateral deafness as allergic manifestation]. / Sordera brusca bilateral como manifestación alérgica.

The paper reports the case of a young woman who presented with a serious bilateral sudden deafness, after the ingestion of a betalactam antibiotic (known as allergic for her) in association with a mucolytic. Account of the course of the clinical events noticed, which are compared with the findings observed in other scarce publications on sudden deafness linked with allergic reactions. Finally the AA. outline a pathogenetic hypothesis in order to explain these cases of deafness involved with digestive allergic reactions.

[Adenoma pleomorphic (mixed tumor) in the nasal septum]. / Adenoma pleomorfo (tumor mixto) en el septum nasal.

A pleomorphic Adenoma was found in the right side of the nasal septum of a 44-year-old female patient. After removal the pathologist's examination could diagnose the mass as a pleomorphic adenoma (mixed tumor) developed from ectopic salivary glands. Early symptoms were nasal obstruction and recurrent spontaneous epistaxis, sometimes preceded by local discomfort. Surgical removal. In this article are discussed some aspects of the these unusual tumors (sitting in the nasal cavity) and the AA. compare their findings with data reported by other publishers.

[Mucoepidermoid carcinoma of the larynx. A case report and review of literature]. / Carcinoma mucoepidermoide de laringe. Aportación de un caso y revisión de la literatura.

A new case of mucoepidermoid carcinoma of the larynx is presented. The microscopic differential diagnosis of mucoepidermoid carcinoma, the several cells stem with its malignancy degrees and its repercussion on prognostic and possible treatments of this rare growth are stressed. A review of the literature is set aside.

[Mucocele of maxillary sinus]. / Mucocele del seno maxilar.

The term mucocele designates a cyst developing from a sinus mucosa, generally the frontal and/or ethmoidal sinuses. Maxillary sinus localization is exceptional however and raises numerous diagnostic problems in daily practice. The antral mucoceles are potentially destructive lesions, often secondary to Caldwell-Luc procedure. In this article are described in some detail the clinical, radiological and histopathological features of true antral mucoceles.

[Hypoacusis and diabetes type II]. / Hipoacusia en diabetes mellitus tipo II.

The relation between diabetes mellitus and hypoacusis is discussed since Jordao, who firstly pointed out to this association in 1854. The disparity of results according several studies are due, after other AA., to the heterogeneous of groups considered. Our study was done resorting to a patients selection and their classification in 2 homogeneous groups following different parameters: age; sex; years of course; verified angiopathic complications: peripheric vasculopathy, microalbuminuria, altered creatinine clearance; malady control: glycosylated hemoglobin. The task consisted in the study of audiometric tracings in 40 patients in order to verify statistic differences of auditive thresholds between the established groups. These courses corresponding to a sensorineural hearing loss with a deep in high tones. But no significatively worse thresholds in patients suffering other angiopathic disorders were detected.

[Diabetic complications and hypoacusia]. / Complicaciones diabéticas e hipoacusia.

The relationship between diabetes mellitus and hypacusia has been discussed since the work of Jordao, in 1857. Numerous authors are openly pro this viewpoint, whereas other deny it. The hypoacusis is typically bilateral, progressive and of neurosensory nature, affecting the higher frequencies. In the etiologic aspect some authors bet for an angiopathic origin, but others suppose a neuropathic cause. We have achieved a comparative study with the aim to get some conclusions that could enlighten this field. Forty patients with diabetes mellitus type II were audiometrically examinees (at threshold and with supraliminar tests) and the results compared with those of a control group. We also assessed several complications of the disease and their possible report with the auditive impairment (retinopathy and neuropathy). We found out a sensorineural, bilateral and symmetrical hearing impairment. Employing the Man Whitney's U test we compare distinct groups and explain the gained outcomes. Bibliographic review of authors defending the vascular or the nervous starting point.

[Otosclerosis and Van der Hoeven's syndrome: a contribution]. / Aportación al estudio de la otosclerosis y del síndrome de Van der Hoeve.

Morphological and microchemical changes that effect to the otosclerotic stape in the Van der Hoeve's syndrome were examined with a scanning electron microscope equipped with an energy dispersive X-ray fluorescence. Using the Ca/P ratio as criterion--measured by the characteristic x-ray fluorescence--it was shown that the Van der Hoeve stape had a higher Ca/P ratio (2.6:1) as compared to the normal stape (2:1). The Van der Hoeve's syndrome lesions as poorly mineralized, with low calcium salt and apparent increase of phosphates. This finding indicates a possible change from hydroxyapatite (or apatite) to brushite, which imply an acidification of bone.

[Review of epiglottitis]. / Revisión de epiglotitis.

Seven cases of acute epiglottitis in children (mean age 38 months) are reported. The major clinical features are described. The review of the literature on current diagnosis and treatment underlined the value of early orotracheal or nasotracheal intubation when this serious condition is suspected.
