[Cervical vertigo from the perspective of an otorhinolaryngologist]. / Sheinoe golovokruzhenie: vzgliad otorinolaringologa.

At present, the skeptical attitude toward the term 'cervical vertigo' (CV) predominates in the ENT-community. Such point of view is attributable to the absence of specific CV symptoms and well-defined diagnostic criteria. The present literature review was designed to consider the results of the clinical observations and experimental investigations obtained during the past 150 years that give evidence of the possibility to regard cervical vertigo as a separate nosological entity. The characteristic signs of this condition are analyzed and systematized. Four CV variants are currently distinguished. The principles of diagnostics and treatment of cervical vertigo are discussed and general concept of CV is formulated.

[Occupational deafness in workers of locomotive crew and its association with risk factors].

The authors studied relationship between occupational neurosensory deafness and risk factors in locomotive crew workers. Examination covered 173 locomotive crew workers divided into 2 groups: group 1--with occupational neurosensory deafness (n = 85) and group 2--without occupational neurosensory deafness (n = 88). Study covered occupational factors and calculated effective dose connected to length of service for exposure assessment. Complex clinical and laboratory study was performed. For signs structure analysis, principal components method and chances ratio were used. Occupational neurosensory deafness appeared to be reliably connected with length of service, arterial hypertension, dyslipidemia--with OR equals 5.7 (95% CI: 2.98-11.00), 1.88 (95% CI: 1.03-3.43) and 2.79 (95% CI: 1.5-5.18) respectively. That necessitates correction of hypertension and dyslipidemia.
