[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.

[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.

[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.

[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.

[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.

[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.
