Introduction: Patients undergoing surgery are anxious owing to the surgery, anesthesia, and unfamiliar environment of the operation theater. This anxiety can hamper the health and recovery of the patients. Among various nonpharmacologic modalities available, music can be used as a coping strategy to change uncomfortable conditions to the pleasant ones. Aims: To evaluate the role of music on perioperative anxiety, hemodynamic parameters, and patient satisfaction in patients undergoing orthopedic surgeries under spinal anesthesia. Settings and design: Tertiary care hospital, randomized control trial. Materials and methods: The study was conducted after approval by Hospital Ethical Committee on 70 adult patients of either gender scheduled to undergo lower limb surgeries under spinal anesthesia. In group M (n = 35), patients listened to standard relaxation music, and in group C (n = 35), patients listened to standard operation theater noise tape through noise canceling headphones. The intraoperative hemodynamic parameters were recorded. Perioperative anxiety was assessed using visual analog scale for anxiety. Sedation score was observed using observer’s assessment of alertness/sedation scale. Patient’s satisfaction was also assessed in both the groups. Statistical analysis: Student t test, Chi-squared test, and paired sample t test. Results: In group M, heart rate was lower when compared with group C. The difference was statistically significant at 10 minutes of assessment (P = 0.003) and statistically highly significant (P < 0.001) for rest of the time period. Statistically significant lower respiratory rate was there in group M when compared with group C (P = 0.05). Patients were more satisfied in the music group when compared with control group. Conclusion: The potential of music therapy can be used to allay patient anxiety, stabilize hemodynamics, and improve patient satisfaction.

Context: Cytomegalovirus (CMV) represents the leading congenital viral infection in humans. Although congenital CMV due to vertically transmitted infections is the main cause of CMV-related diseases, adult CMV infections might still be of clinical significance. It is still discussed how far CMV seropositivity, due to horizontal infection in immunocompetent adults, is able to induce significant dysfunction. The present study investigates in how far CMV seropositivity is an additional risk factor for an increasing susceptibility to sensorineural hearing loss induced by acoustic injury during adulthood in a guinea pig CMV (GPCMV) model of noise-induced hearing loss (NIHL). Methods: Two groups (GPCMV seropositive vs. seronegative) of normal hearing adult guinea pigs were exposed to a broadband noise (5–20 kHz) for 2 hours at 115 dB sound pressure level. Frequency-specific auditory brainstem response recordings for determination of auditory threshold shift were carried out and the number of missing outer hair cells was counted 2 weeks after the noise exposure. Results: The data show a slightly increased shift in auditory thresholds in seropositive animals compared to the seronegative control group in response to noise trauma. However, the observed difference was significant at least at high frequencies. The differences in threshold shift are not correlated with outer hair cell loss between the experimental groups. Conclusion: The results point to potential additional pathologies in a guinea pig NIHL model in correlation to GPCMV seropositivity, which should be taken into account when assessing risks of latent/reactivated CMV infection. Due to the relatively slight effect in the present data, the aim of future studies should be a more detailed consideration (e.g., larger sample size) and to localize possible target structures as well as the significance of the infection route.

Context There may be a connection between tinnitus, a common disease in society, and psychiatric disorders. When the literature is reviewed, it has been realized that more data are needed to elucidate this issue. Aims The aim of this study is to compare the symptoms of anxiety sensitivity, anxiety, depression, and attention-deficit/hyperactivity disorder (ADHD) symptoms in patients with tinnitus with healthy individuals and to investigate the relationship between tinnitus and psychiatric disorder symptoms. Settings and design This study was designed as a case–control study. Materials and methods Fifty-one patients with tinnitus and 51 healthy controls were enrolled in this study. Clinical severity of the psychiatric variables were evaluated by Beck depression inventory, Beck anxiety inventory (BAI), anxiety sensitivity index-3, and adult ADHD self-report scale (ASRS) in patient and control groups. Statistical analysis used Variables are presented as either a number, a percentage, a mean ± standard deviation, or frequency. Chi-squared, Student t tests, and logistic regression analysis were used to examine the relationship between variables. Results Logistic regression analysis results indicated that a significant predictive power of BAI for the presence of tinnitus. Based on a backward-elimination regression analysis, ASRSs (inattention subscale scores) were considered to predict a higher tinnitus handicap inventory score. Conclusion These findings provide additional evidence that anxiety and attention-deficit (inattentive) symptoms could contribute to the pathophysiology of tinnitus.

Objective: Adolescents may be at risk of noise-induced hearing loss due to recreational sound. The aim of this study was to examine the role of distortion product otoacoustic emissions (DPOAEs) in screening for early stages of high-frequency loss such as can be observed in noise-induced hearing loss. Setting and design: This cross-sectional study was embedded within Generation R, an ongoing prospective birth cohort study in Rotterdam, The Netherlands. Data were collected from April 2016 to September 2019. Methods: A total of 3456 adolescents with a mean age of 13 years and 8 months old (standard deviation ± 5 months) were included. Pure-tone thresholds were measured in a sound-treated booth. DPOAEs were recorded using an ILO V6 analyzer with primary levels of 65/55 dB SPL and frequency ratio f₂/f₁ of 1.22. Subjects had normal middle ear function at the time of assessment, based on tympanometry results. Results: Measurements in 6065 ears showed that DPOAE levels tend to decrease with increasing pure-tone thresholds. However, the intersubject variability of DPOAE levels in ears with the same threshold was large. DPOAE levels could reasonably identify early stages of high-frequency hearing loss. Conclusion: The findings of present study indicate that DPOAE measurements can potentially be used for adolescents hearing screening in the high frequencies. Future research is needed to optimize test performance.
