Caloric test and simultaneous recording of sympathetic skin response

Conclusions. It was found that there was a close correlation between sympathetic skin response (SSR) parameters and nystagmus parameters obtained in caloric tests. Further studies are needed to investigate the clinical correlation of these findings. Objectives. To investigate whether the caloric response creates a measurable SSR and, if so, to compare the SSR parameters with the nystagmus parameters and the feelings of the patient. Material and methods. Patients completed an autonomic symptom questionnaire (ASQ) regarding their past history of autonomic symptoms. They used a visual analog scale (VAS) to assess the severity of symptoms during simultaneous SSR and caloric tests. Symptoms were also noted separately by the investigator. Results. Eighteen patients were included in the study (13 females, 5 males). Eight of the patients had central and 10 had peripheral vertigo. The mean VAS score was 6.6 +/- 1.9 and the mean ASQ score was 7.2 +/- 3.6. In terms of the recorded parameters, there were no significant differences between patients with central and peripheral vertigo, males and females or warm and cold irrigation. The number of SSR waves increased significantly when the slow-phase velocity was > 26 degrees/s (p < 0.01) and the nystagmus latency was <= 27 s (p < 0.05). The VAS score was also correlated with the number of SSR waves (p < 0.01).C1 Pamukkale Univ, Sch Med, Dept Otolaryngol, Denizli, Turkey

Evidence-Based Medical Treatment in Peripheral Vestibular Diseases

Evidence-based medicine grades scientific research articles according to their structural specification. It represents an evidence value that we can count on for clinical applications. In this review, we evaluate our medical treatment algorithm in peripheral vestibular diseases according to evidence-based medicine rules. Benign par-oxysmal positional vertigo, vestibular paroxysmia, labyrinthitis, vestibular neuritis, otosclerosis, autoimmune inner ear disease, Meniere's disease, and migraine-associated vertigo are discussed
