[Clinical significance of positional nystagmus].

Clinical and otoneurological examinations were carried out during 35 years in 1176 patients with various vestibular disorders. Positional nystagmus (PN) was found in 478 patients (40.4%). Horizontal-rotatory or rotatory PN was reported in the inner ear disorders; bilateral, horizontal, vertical, diagonal and multiple PN occurred only in disturbances of the central nervous system. It was found that PN and spontaneous nystagmus (SN) are the signs of different phases of the same process; the appearance of the PN after SN in the labyrinthine lesions is the symptom of partial compensation of the vestibular function. The examination of the PN is important to widen potentialities of the neuro-otological diagnosis especially in out patient clinic.

[Otogenic intracranial complications in an urban emergency service hospital].

The problem of otogenic intracranial complications is very important for medical practice. This paper presents data on the incidence, clinical development and outcome of intracranial complications of purulent otitis media. During 1979-1988 the ENT Department of the City First Aid Hospital treated 82 patients with otogenic intracranial complications, which developed often in the case of acute than chronic otitis media. The lethality rate caused by otogenic meningitis and meningoencephalitis was 0.95% in the patients with acute otitis media and 0.5% in the patients with chronic otitis media. In view of this, it is recommended to extend the list of indications for hospitalization of patients with acute otitis media. It is strongly recommended to admit to hospitals patients with acute otitis media caused by severe flu, pregnant women, patients with severe visceral pathologies, and old age patients.

[Positioning nystagmus].

256 patients with postural vertigo were examined clinically and neurootologically. Positioning nystagmus (PN) was detected in 209 (81.6%) of them. Postural vertigo arose as a result of inner ear diseases or traumas (n = 52), affection of cervical spine (n = 24), cardiovascular diseases (n = 97), organic impairment of the posterior cranial fossa (n = 20), endocrine disorders (n = 5), intoxication from chronic infection foci (n = 24), neuroses with vegetative dysfunction (n-34). PN emerged, as a rule, in patients having 2-3 of the above conditions. A genesis scheme of PN is outlined with regard to interaction of the main pathogenic factors influencing the vestibular system. Horizontal-rotatory or rotatory, vertical, diagonal, bilateral horizontal or multiple PN are characteristic for peripheral vestibular dysfunctions and central vestibular dysfunction, respectively. It is reasonable to perform position tests after assessment of the patients' nervous and cardiovascular systems, the condition of cervical spine.
