Introduction  Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo, and it is characterized by episodes of vertigo roundabout when the head is moved. A systematic review was performed using the most important scientific databases. This review included studies published in English in the last ten years, performed in adults, with emphasis on the diagnosis and treatment of BPPV. Objective  To investigate the long-term effectiveness of vestibular rehabilitation (VR) in patients with BPPV and the rate of recurrence of symptoms. Data Synthesis  A total of 38 studies were identified, of which only 12 met the inclusion criteria. The majority of the studies stated that VR is effective in decreasing the symptoms, with a short-term efficacy of 84.7%, and 89.2% in the long term in the reviewed studies. Conclusion  Valuable studies show the beneficial effects of the maneuvers for the treatment of BPPV and their long-term effectiveness. This strengthens the conclusion that this treatment is effective in resolving symptoms and decreasing recurrences.

In addition to positional vertigo, it is quite common for patients with benign paroxysmal positional vertigo (BPPV) to present complaints associated with balance problems and a feeling of dizziness even after repositioning maneuvers. Objective: It was to evaluate the additional effects of vestibular rehabilitation exercises as a therapeutic resource in the treatment of BPPV, to improve symptoms and reduce recurrence. Study Design: This was an experimental, prospective, randomized, controlled study. Setting: Instituto Brasiliense de Otorrinolaringologia (IBORL) from August 2016 to September 2017. Patients: Thirty-two individuals, both men and women, over 18 years of age with BPPV. Intervention: They were randomly assigned to two groups: the control group (n = 15) performing only the maneuver technique as treatment and the experimental group (n = 17) performing the maneuvers and vestibular rehabilitation exercises. Patients underwent treatment and responded to the dizziness handicap inventory (DHI) and visual analog scale (VAS) questionnaires for comparison between groups. Participants were followed up for 6 months to observe recurrence of symptoms. Main Outcome Measures: To investigate the additional effects of vestibular exercises in the treatment of BPPV. Results: The experimental group had a lower level of dizziness in the posttreatment period (p < 0.05) and a lower incidence of recurrences (p = 0.038) than the control group. Conclusions: Vestibular exercises performed after repositioning treatments for BPPV increased the overall efficacy of treatment by improving symptoms with a lower rate of recurrence.

Objective To test the hypothesis that caffeine can influence tinnitus, we recruited 80 patients with chronic tinnitus and randomly allocated them into two groups (caffeine and placebo) to analyze the self-perception of tinnitus symptoms after caffeine consumption, assuming that this is an adequate sample for generalization. Methods The participants were randomized into two groups: one group was administered a 300-mg capsule of caffeine, and the other group was given a placebo capsule (cornstarch). A diet that restricted caffeine consumption for 24 hours was implemented. The participants answered questionnaires (the Tinnitus Handicap Inventory—THI, the Visual Analog Scale—VAS, the profile of mood state—POMS) and underwent examinations (tonal and high frequency audiometry, acufenometry (frequency measure; intensity measure and the minimum level of tinnitus masking), transient otoacoustic emissions—TEOAE and distortion product otoacoustic emissions—DPOAE assessments) at two timepoints: at baseline and after capsule ingestion. Results There was a significant change in mood (measured by the POMS) after caffeine consumption. The THI and VAS scores were improved at the second timepoint in both groups. The audiometry assessment showed a significant difference in some frequencies between baseline and follow-up measurements in both groups, but these differences were not clinically relevant. Similar findings were observed for the amplitude and signal-to-noise ratio in the TEOAE and DPOAE measurements. Conclusions Caffeine (300 mg) did not significantly alter the psychoacoustic measures, electroacoustic measures or the tinnitus-related degree of discomfort.

OBJECTIVE: To evaluate Newborn Hearing Screening Program of Hospital Regional de Sobradinho, from January 2016 to December 2017, according to Multiprofessional Committee on Auditory Health parameters and Joint Committee on Infant Hearing (JCIH) recommendations, as well as to describe the prevalence of risk factors for hearing loss within the study population and their impact on the respective program. METHOD: This is a quantitative, cross-sectional and retrospective study that carefully analyzed registration books of screened newborns. It was established the prevalence of “pass” and “fail” in test and retest, retest percentage of attendance and referral for audiological diagnosis. Risk factors for hearing loss were described, as well as their influence on “pass” and “fail” rates. Inferential statistical analysis was performed using chi-square test and Anderson-Darling test, with 5% reliability index. RESULTS: A total of 3,981 newborns were screened; 2,963 (74.4%) presented no risk factors whereas 1,018 (25.6%) did, prematurity being the most frequent (51.6%). In the test, 166 (4.2%) failed and 118 (71.1%) attended the retest. The referral rate for diagnosis was 0.3%. CONCLUSION: Regarding the percentage of referral for diagnosis, the program reached indexes recommended by the Joint Committee on Infant Hearing and Multiprofessional Committee on Auditory Health. The most prevalent risk factor within the population was prematurity.

Meniere's disease is characterized by recurrent vertigo, luctuating hearing loss, and persistent tinnitus. Cafeine consumption in modern society is a widespread and culturally accepted habit; however, there is no consensus about its mechanism of action in various organs and systems, including the auditory and vestibular. The few clinical studies have shown that abstention from cafeine has litle efect in patients with Meniere's disease, both in relation to vertigo, tinnitus and hearing loss.
