[Leiomyosarcoma of the larynx. Based on one case].

Leiomyosarcoma is a malignant tumour of smooth muscle cells. Usually is found in the gastrointestinal and female genital tracts, but is extremely rare in the larynx. Diagnosis is based in immunohistochemical studies. From the related literature is concluded that this tumour has a very aggressive behavior, with a very bad prognosis in spite of a radical surgery. A case of glottic Laryngeal Leiomyosarcoma (LL) treated with partial surgery is presented, There isn't any evidence of recurrent or metastases after a two years follow-up.

[Primary meningioma of the nasal cavity].

Meningiomas are benign tumors developed from aracnoid meningeal cells. Its primary extracranial and extravertebral onset is a rarity, arising more frequently in the scalp and orbit. Its beginning in nasal fosae is considered exceptional. Diagnosis will be based on cranial CTY scan and histology of the whole tumour once extirpated. A case of advanced primary nasal meningioma is reported. The AA. emphasize the difficulties in presurgical diagnosis in this type of growths.

[Neurosensory hearing loss associated with ischemic heart disease. Features and prognostic values].

The aim of this study was to verify the supposed pathological hearing loss in those patients with ischemic heart disease, as well as to determine its features and possible clinical usefulness. Two groups were made: group A (n = 65), patients admitted for acute episode of ischemic heart disease, group B (n = 60), patients without cardiac or auditive disorders. Auditive assessment included standard PTA and Bera. Cardiologic evaluation was made through cardiac catheterism with coronariography. Results confirm the existence of a clinical association between "perceptive hearing loss" and "ischemic heart disease", independently of the age, with a characteristic pattern of hearing loss, and also show the existence of a high risk subgroup within the population with coronary risk.

[Necrotizing osteitis of tympanal bone. Report of 2 cases].

A large variety of process can cause necrosis of the bony external ear canal, found by means otoscopic examination. Two cases with a final diagnosis or external ear canal cholesteatoma are reported. A revision of the main characteristics of this uncommon entity is performed, with a special emphasis to avoid that the scarcity of clinic symptoms favour its growing in depth.

[Topographic diagnosis of hearing loss in patients with ischemic heart disease. Use of high-rate brain stem evoked response audiometry].

Hearing loss in patients with ischemic heart disease traditionally has been attributed to atheromatous cerebral vascular disease. In this study, the site of the auditory lesion was sought in patients with ischemic heart disease and perceptive hearing loss. Standard brainstem evoked response audiometry (BSER) with increased stimulation rate (ISR) were performed. Sixty-seven patients admitted for coronary artery disease were examined. Fifty-seven recordings were complete and evaluable. All the cases of hearing loss were endocochlear. In 4 patients. BSER and ISR detected subclinical retrocochlear lesions that were compatible with ischemic disease. The results suggest that selective early cochlear ischemia can occur in young persons with heart disease. The sensitivity of BSER with ISR for detecting ischemic brainstem lesions was confirmed.
