[Linguistic adaptation and validation of the voice handicap index (VHI)-30 in patients with dysphonia into Russian]. / Lingvisticheskaya adaptatsiya i podtverzhdenie primeneniya russkoi versii oprosnika Indeks izmeneniya golosa-30 (Voice Handicap Index (VHI)-30) u patsientov s disfoniei.

Purpose of the study is to assess the internal consistency, reliability of retesting and clinical reliability of the Russian version of the Voice Handicap Index (VHI)-30 questionnaire. MATERIAL AND METHODS: It is prospective observational study. The original English version of the VHI-30 questionnaire was translated into Russian by two independent researchers (professional translators). The final Russian version (VHI-30rus) was formulated by a third researcher (otorhinolaryngologist) on the basis of these two translations, and then translated back into English. The 181 participants were included in this study. The main group patients (n=91) were additionally divided into subgroups in accordance with the form of dysphonia: 65 (71.4%) patients had functional and organic dysphonia, 8 (8.8%) had chronic inflammatory diseases of the larynx, 7 (7.7%) - benign neoplasms of the larynx (singing nodules, polyps, cysts), 11 (12.1%) - unilateral laryngeal paralysis. The control group consisted of 90 people without voice disorders. Internal consistency (Cronbach's α coefficient), retest reliability (intraclass correlation coefficient (ICC) VHI-30, comparison of VHI-30 indicators of patients and studied control group (Mann-Whitney U-test, Kruskal-Wallis test) and correlation with the overall severity of dysphonia (Spearman's ρ rank correlation coefficient) were determined. RESULTS: In the patient group, we observed excellent internal consistency for VHI-30rus (α=0.95) and good internal consistency for all VHI-30rus subscales: physical (α=0.88), functional (α=0.88), and emotional (α=0.88). The intraclass correlation coefficient (ICC) indicated high retest reliability for patients (0.99) and control group subjects (0.84). The 30-item mean total values for patients with dysphonia were statistically significantly higher than for control group participants (p<0.001). A correlation was found between the overall VHI-30rus value and the overall severity of dysphonia (ρ=0.748, p<0.001). In the patient's group, female and male participants showed a statistically insignificant difference in the total value of VHI-30rus (Mann-Whitney U-test, p<0.001). There was a correlation in terms of VHI-30rus indicators in different subgroups of the patient group and the control group (Spearman's correlation coefficient: functional dysphonia - 0.942; chronic laryngitis - 0.756; unilateral laryngeal paralysis - 0.888; benign neoplasms - 0.982; control group studied - 0.882). CONCLUSION: As a result of this study, the VHI-30 questionnaire was translated from English into Russian for use in the Russian-speaking environment. The study showed good internal consistency, retest reliability, and clinical validity for the Russian version of the VHI-30rus questionnaire. The VHI-30rus questionnaire can be recommended for use in clinical practice for patients with dysphonia.

[Diagnostics of nasal bone fractures with the use of ultrasound study techniques].

The objective of the present study was to estimate the effectiveness of ultrasound diagnostics of nasal bone fractures, compare it with the results of clinical examination, X-ray and CT imaging of nasal bones. The data of the analysis of clinical symptoms and instrumental studies are compared with those of X-ray and ultrasound investigations of intact and fractured bones including the cases of persistent post-traumatic deformation of the nose. It is concluded that the ultrasonic study of nasal bones is a more accurate method for diagnostics of their fractures compared with X-ray examination (p<0.05); specifically, it allowed the lateral displacement of bone fragments to be documented.
