[Computerized tomography in the study of malignant tumors of the larynx].

A systematic investigation was carried out on 93 patients suffering from laryngeal tumours who underwent computed tomography and xeroradiography. A comparison is made between CT, xerographic, clinical and endoscopic findings. The value is stressed of functional informations obtained from CT performed during quiet breathing and phonation. The outstanding value of CT is the accuracy in definition of tumor extension and involvement of the laryngeal and paralaryngeal tissues. CT can be useful in diagnosis of regional lymph nodes metastases. The correct evaluation of the tumour is greatly helpful in surgical treatment and radiotherapy planning.

Quantification of vestibular nystagmus by an interactive computer program.

An interactive program for the analysis of nystagmus is presented, and some results obtained by processing postrotational responses are reported. The program is provided with a special subroutine which gives a quantification of the rhythm and regularity of the response through the histograms of the ratios between the duration of successive intersaccadic intervals and between the amplitudes of successive fast components. The consideration of these histograms has been proved to be highly significant in discriminating between normal and pathological responses.
