Effect of vitamin B12 deficiency on otoacoustic emissions [Effetti del deficit della vitamina B12 sulle otoemissioni acustiche]

Karli R. | Gül A. | Ugur B.

The aim of this study was to investigate the possible association between otoacoustic emission (OAE) values and cochlear function in patients with vitamin B12 deficiency and no evidence of symptomatic hearing loss. Two groups were studied: Group 1: patients with vitamin B12 deficiency; Group 2: a matched control group of patients with normal vitamin B12 levels. There was no evidence of symptomatic hearing loss in either group. Transiently evoked OAEs (TEOAEs) and spontaneous OAEs (SOAEs) were recorded. A comparative analysis of the studied parameters revealed that results at TEOAE 1000, SOAEs ...Daha fazlası

A misdiagnosed keratoacanthoma turned out to be a metastatic parotid carcinoma [Erronea diagnosi di keratoacantoma in un caso di metastasi parotidea da carcinoma squamoso]

Tas E. | Birol Ugur M. | Gul A. | Cinar F. | Uzun L. | Dogan Gun B.

Distinguishing keratoacanthoma from well-differentiated squamous-cell carcinoma is often difficult on account of the clinical and histopathological similarities between them. Since the outcome of treatment depends on identifying the correct diagnosis and having the correct treatment on time, it is essential to differentiate keratoacanthoma and squamous-cell carcinoma as soon and accurately as possible. A paradigmatic case is herein reported. An 85 year-old female underwent total parotidectomy and ipsilateral neck dissection due to the squamous-cell carcinoma of the parotid gland. The investiga ...Daha fazlası
