- Pathophysiology and Diagnosis of Vertebrobasilar Insufficiency: A Review of the Literature(2017) LIMA NETO, Arlindo Cardoso; BITTAR, Roseli; GATTAS, Gabriel Scarabotolo; BOR-SENG-SHU, Edson; OLIVEIRA, Marcelo de Lima; MONSANTO, Rafael da Costa; BITTAR, Luis FelipeAbstract Introduction Vertebrobasilar insufficiency is defined as transitory ischemia of the vertebrobasilar circulation. Dizziness, vertigo, headaches, vomit, diplopia, blindness, ataxia, imbalance, and weakness in both sides of the body are the most common symptoms. Objective To review the literature regarding the three available diagnostic testing in patients with dizziness complaints secondary to vertebrobasilar insufficiency (VBI): magnetic resonance angiography; transcranial Doppler ultrasound; and vertebrobasilar deprivation testing. Data Synthesis We selected 28 studies that complied with our selection criteria for appraisal. The most frequent cause of the hemodynamic changes leading to VBI is atherosclerosis. The main clinical symptoms are dizziness, vertigo, headaches, vomit, diplopia, blindness, ataxia, imbalance, and weakness in both sides of the body. Even though arteriography is considered the most important exam to diagnose the disease, the inherent risks of this exam should be taken into consideration. The magnetic resonance angiography has been widely studied and is a good method to identify and localize any occlusions and stenosis in both neck and intracranial great vessels. Conclusion Each patient with a suspected diagnosis of VBI should be individually evaluated and treated, taking in consideration the pros and cons of each diagnostic testing and treatment option.
- Sensitivity of caloric test and video head impulse as screening test for chronic vestibular complaints(2017) MEZZALIRA, Raquel; BITTAR, Roseli Saraiva Moreira; BILECKI-STIPSKY, Marcia Maria do Carmo; BRUGNERA, Cibele; GRASEL, Signe SchusterOBJECTIVE: This study compared the results of the caloric test with those of the video head impulse test obtained during the same session and evaluated whether the former can be used to screen for non-acute vestibular dysfunction. METHODS: A total of 157 participants complaining of dizziness with vestibular characteristics of varying durations and clinical courses completed the caloric test and video head impulse test. RESULTS: Significantly more caloric test results than video head impulse test results were abnormal. CONCLUSIONS: The results of the caloric test and video head impulse test are distinct but complement each other. Within our sample, the caloric test was more sensitive for vestibular dysfunction. Therefore, the video head impulse test is not a suitable screening tool of the vestibular system in patients with chronic complaints.
- Preoperative vestibular assessment protocol of cochlear implant surgery: an analytical descriptive study(2017) BITTAR, Roseli Saraiva Moreira; SATO, Eduardo Setsuo; RIBEIRO, Douglas Josimo Silva; TSUJI, Robinson KojiIntroduction: Cochlear implants are undeniably an effective method for the recovery of hearing function in patients with hearing loss. Objective: To describe the preoperative vestibular assessment protocol in subjects who will be submitted to cochlear implants. Methods: Our institutional protocol provides the vestibular diagnosis through six simple tests: Romberg and Fukuda tests, assessment for spontaneous nystagmus, Head Impulse Test, evaluation for Head Shaking Nystagmus and caloric test. Results: 21 patients were evaluated with a mean age of 42.75 +/- 14.38 years. Only 28% of the sample had all normal test results. The presence of asymmetric vestibular information was documented through the caloric test in 32% of the sample and spontaneous nystagmus was an important clue for the diagnosis. Bilateral vestibular areflexia was present in four subjects, unilateral arreflexia in three and bilateral hyporeflexia in two. The Head Impulse Test was a significant indicator for the diagnosis of areflexia in the tested ear (p = 0.0001). The sensitized Romberg test using a foam pad was able to diagnose severe vestibular function impairment (p = 0.003). Conclusion: The six clinical tests were able to identify the presence or absence of vestibular function and function asymmetry between the ears of the same individual.

- Hearing performance as a predictor of postural recovery in cochlear implant users(2017) GRETERS, Mario Edvin; BITTAR, Roseli Saraiva Moreira; GRASEL, Signe Schuster; OITICICA, Jeanne; BENTO, Ricardo FerreiraObjective: This study aimed to evaluate if hearing performance is a predictor of postural control in cochlear implant (CI) users at least six months after surgery. Methods: Cross-sectional study including (CI) recipients with post-lingual deafness and controls who were divided into the following groups: nine CI users with good hearing performance (G+), five CI users with poor hearing performance (G-), and seven controls (CG). For each patient, computerized dynamic posturography (CDP) tests, a sensory organization test (SOT), and an adaptation test (ADT) were applied as dual task performance, with first test (FT) and re-test (RT) on the same day, including a 40-60 min interval between them to evaluate the short-term learning ability on postural recovery strategies. The results of the groups were compared. Results: Comparing the dual task performance on CDP and the weighted average between all test conditions, the G + group showed better performance on RT in S0T4, SOT5, SOT6, and CS, which was not observed for G - and CG. The G - group had significantly lower levels of short-term learning ability than the other two groups in SOT5 (p= 0.021), SOT6 (p= 0.025), and CS (p= 0.031). Conclusion: The CI users with good hearing performance had a higher index of postural recovery when compared to CI users with poor hearing performance.

- Efficacy of Carbon Microcoils in Relieving Cervicogenic Dizziness(2017) BITTAR, Roseli; ALVES, Nédison Gomes Paim; BERTOLDO, César; BRUGNERA, Cibele; OITICICA, JeanneAbstract Introduction Cervical pain contributes to postural deviations and imbalance. Nanotechnology may be used for the treatment of neck pain by fixing to the skin small rounds silicone patches containing double spiral carbon nanotubes arranged in the form of a coil (Helical), which would then relieve dizziness caused by muscular contraction. Objective The objective of this study is to Evaluate pain and dizziness scores before and after Helical patches effect on cervicogenic dizziness treatment. Methods The selected patients should have neck pain arising from muscle contraction with loss of balance or instability lasting more than 90 days and normal electrooculography. Treatment consisted of placing 10 Helical patches distributed as follows: two in the upper cervical area, two in the lower cervical area (near the 5th and 6th vertebrae), two in the upper trapezius muscle area (between neck and shoulder), and four in the tender point area (as reported by the patient). Using a Visual Analogue Scale (VAS), we matched pain and dizziness scores from Day 1 to those from Day 15 and Day 30 using Mann-Whitney test. Results There was a significant difference between pain score reported on Day 1 and Day 15 (Z = 2.43, U = 5, p = 0.01). We also found significant differences between dizziness scores reportedondays1 and15 (Z = 2.62, U = 3.5, p = 0.01) and days 1 and 30 (Z = 2.36, U = 5.5, p = 0.01). Conclusion The Helical patches seem to be an effective treatment for cervicogenic dizziness.
