The so called β-wave of the binaural interaction component (BIC) in auditory brainstem responses (ABR) has been shown to be an objective measure for binaural interaction (BI). This component is the arithmetical difference between the sum of the monaurally evoked ABRs and the binaurally evoked ABR. Unfortunately, these neural responses are known to be very fragile and as a result the calculated BIC. An additional issue is, that the findings of this measurement are predominantly needed in people with hearing loss who may use hearing devices like hearing aids (HA) or cochlear implants (CI), thus they are not able to use headphones (like in conventional ABR measurements) during the detection of possible BI...

Traditional indirect standard measurement of blood pressure is based on hearing Korotkoff sounds to determine systolic and diastolic blood pressure. However, the problem exists among different types of automatic blood pressure monitoring devices because of no standard algorithm for estimating accurate blood pressure values. Aim of the study was to develop an automatic blood pressure measurement device based on Korotkoff sounds. PVDF(poliyvinylidene fluoride) film was used as a contact microphone to detect Korotkoff sounds on the brachial artery, and pressure sensor was used to obtain cuff pressure...

A primary complaint of hearing-impaired individuals involves poor speech understanding when background noise is present. Hearing aids and cochlear implants often allow good speech understanding in quiet backgrounds. But hearing-impaired individuals are highly noise intolerant, and existing devices are not very effective at combating background noise. As a result, speech understanding in noise is often quite poor. In accord with the significance of the problem, considerable effort has been expended toward understanding and remedying this issue...

The link between gait parameters and hearing loss is not well understood. The objective of this study was to investigate the effects of the gait ground reaction forces, their time to peak, vertical loading rate, impulses and free moment during gait in deaf and hearing children. Thirty male children were equally divided into a healthy group and a group with hearing loss problems (Deaf group). Ground reaction forces were analyzed during barefoot walking. MANOVA test was used for between group comparisons. The significance level was set at p<0...

The ability to understand speech in the presence of competing sound sources is an important neuroscience question in terms of how the nervous system solves this computational problem. It is also a critical clinical problem that disproportionally affects the elderly, children with language-related learning disorders, and those with hearing loss. Recent evidence that musicians have an advantage on this multifaceted skill has led to the suggestion that musical training might be used to improve or delay the decline of speech-in-noise (SIN) function...

INTRODUCTION: A consensus is emerging amongst otologists that obliteration of the mastoid cavity that results after modified radical mastoidectomy is a sound option to prevent cavity related problems such as otorrhoea, infection, granulation tissue and hearing loss. A variety of techniques have been proposed to perform the obliteration. AIM: The present study aimed to compare the conventional method of mastoid cavity obliteration by vascularised temporalis myofascial flap with deep temporal fascial-periosteal flap in canal wall down mastoidectomy...

Noise-induced hearing loss (NIHL) is a global health problem affecting over 5% of the population worldwide. We have shown previously that acute noise-induced cochlear injury can be ameliorated by administration of drugs acting on adenosine receptors in the inner ear, and a selective A1 adenosine receptor agonist adenosine amine congener (ADAC) has emerged as a potentially effective treatment for cochlear injury and resulting hearing loss. This study investigated pharmacokinetic properties of ADAC in rat perilymph after systemic (intravenous) administration using a newly developed liquid chromatography-tandem mass spectrometry detection method...

Tinnitus is a phantom sound that can be a symptom of various disorders such as hearing loss, cardiovascular diseases, neurological disorders, diabetes or tumors. Because of the inability to divert the auditory attention from tinnitus sound, patients suffer with insomnia, problems with concentration and other psychological conditions, in some extreme cases including major depression symptoms. The auditory character of tinnitus induces the patients to seek help predominantly at the otolaryngologist practice. The first aim of a physician is to establish the cause of tinnitus and to measure its audiological properties...

Rinze Anthony Tange, Albert Mudry
OBJECTIVES/HYPOTHESES: In 1884, Johann Constantin August Lucae (1835-1911), a German otologist from Berlin, introduced a new "method to mechanically treat chronic troubles of the mobility of the hearing organ transmission apparatus." It consisted in the use of a springy pressure probe to directly mobilize the handle of the malleus. The aim of this study is to trace the invention, clinical use, technological modifications, and ultimate extinction of this instrument. METHOD: Review of Lucae's publications, comments by his colleagues, and trade catalogues published between 1880 and 1940...

: 114 Background: The Commission on Cancer mandates psychosocial distress screening for patients with cancer, as well as documentation of referrals made to address sources of distress. Patients in safety net settings, who are vulnerable to significant economic and social stressors, may benefit from such screening; however, it is unclear if patients can access needed services and if their needs change over time. We examined the experience of cancer patients in an urban safety-net healthcare system to identify areas of improvement in the provision of support services...

Lucy is a 12-year-old Latina whose mother brought her to the pediatric clinic for help with her anxiety symptoms, "hearing voices," and episodes of "spacing out." Lucy did not cry at birth secondary to vocal cord paralysis and still has the tracheostomy performed at a few days of life. In addition to her neonatal intensive care unit stay, she has been hospitalized for pneumonia. Her mother says she is "sickly" and has a weak immune system due to her asthma symptoms. Lucy also experiences somatic complaints related to gastroesophageal reflux and constipation...

The movement to advance the clinical nurse leader (CNL) as an innovative new role for meeting higher health care quality standards continues with CNL programs offered on-line at colleges and universities nationwide. Collaborative learning activities offer the opportunity for CNL students to gain experience in working together in small groups to negotiate and solve care process problems. The challenge for nurse educators is to provide collaborative learning activities in an asynchronous learning environment that can be considered isolating by default...

OBJECTIVE: A central problem in computational neuroscience is to characterize brain function using neural activity recorded from the brain in response to sensory inputs with statistical confidence. Most of existing estimation techniques, such as those based on reverse correlation, exhibit two main limitations: first, they are unable to produce dynamic estimates of the neural activity at a resolution comparable with that of the recorded data, and second, they often require heavy averaging across time as well as multiple trials in order to construct statistical confidence intervals for a precise interpretation of data...

Estimates indicate that 14 million Americans have olfactory dysfunction. As with other senses, such as sight and hearing, olfaction frequently declines with age. Impaired olfaction can be a warning sign of Parkinson's disease, sometimes occurring before motor symptoms develop. It's also an initial symptom of Alzheimer's dementia (AD); the amyloid plaques and tangles characterizing AD invade the olfactory bulb and hippocampus early in its course, hampering odor identification. Olfactory dysfunction is associated with some serious problems, including inability to smell warning odors (fire, gas) and impaired ability to taste food...

BACKGROUND: There are no nationally representative population-based studies investigating the relationship between physical activity, chronic conditions and multimorbidity (i.e., two or more chronic conditions) in low- and middle-income countries (LMICs), and studies on a multi-national level are lacking. This is an important research gap, given the rapid increase in the prevalence of chronic diseases associated with lifestyle changes in these countries. This cross-sectional study aimed to assess the association between chronic conditions, multimorbidity and low physical activity (PA) among community-dwelling adults in 46 LMICs, and explore the mediators of these relationships...
