[Mechanisms of interactions between different types of nystagmus].

Basing on the original and literature data it is suggested that all types of nystagmus are formed by the same complex system. Under combined stimulation, impulses from the sensory systems are integrated not only in the vestibular nuclei, but also in a series of structures at cortical-subcortical level. The integration proceeds with its own polarity (activating or inhibiting) when a signal alters the ability of a structure to respond to another inputting signal. In this way the thresholds are permanently modified in the integrating structures of the system. It results in increasing or decreasing effect of the outputting reaction of the system. Final response of integrating process reaches the effector level of the nystagmus generation, namely paramedial or mesencephalic regions of pontine reticular formation and spreads further to oculomotor nuclei.

[Computed tomography in the diagnosis of postoperative changes of paranasal sinuses].

Basing on the evidence obtained at examinations of 37 patients within 15-year follow-up after surgery on the maxillary and ethmoidal sinuses, the authors analyse potentialities and techniques of computed tomography in diagnosis of the developments in operated on paranasal sinuses. CT demonstrated advantages in examination of paranasal sinus walls and soft tissue alterations in them.

[The function of the oxidant-antioxidant system in patients with laryngeal cancer].

Lipid peroxidation and antioxidant system were studied at hospital admission, on postoperative day 1, 3 weeks and half a year after surgery in 86 patients with different stages of laryngeal cancer. A correlation is stated between lipid peroxidation disturbances and the defects in the protective antioxidant system. Low-frequency laser irradiation of autoblood produced a clinically beneficial effect and stabilized biochemically the relations between lipid peroxidation and antioxidant systems.

[Contact laser surgery in the treatment of laryngeal neoplasms].

YAG-ND laser contact surgery in combination with tracheal puncture jet ventilation of the lungs were used in managing 128 patients with laryngeal cancer (T1-T2) and 129 patients with benign lesions of the larynx. A complete response was achieved in 97.3% of stage I and 94.4% of cancer stage II patients. The recurrences occurred in 7 out of 129 patients with benign lesions.

[Skin tumors of the face: experience in contact laser excision].

A clinical review is provided of 1558 neoplasm cases of facial skin new growth of different origin and site. The technique of YAG-Nd laser in contact mode application is described. Specific postoperative features are correlated with tumor extension, its histological type and site. In all the cases, except skin papillomatosis, there were no primary recurrences.

[Low-intensity laser irradiation in otorhinolaryngology].

Low-intensity laser irradiation is a modality widely practiced in otorhinolaryngology. Basing on extensive personal experience and literature data the authors provide ENT specialists with relevant techniques and parameters of the radiation for different otorhinolaryngological diseases.
