Treatment of Tinnitus Using Theta Burst Based Repetitive Transcranial Magnetic Stimulation-A Single Blinded Randomized Control Trial.

Objective: To determine whether theta burst repetitive transcranial magnetic stimulation is an effective treatment for chronic tinnitus compared with a control stimulus.

Study Design: A two-arm, single-blind, randomized controlled trial comparing an active treatment group to a placebo control group.

Setting: Neurotology department of a tertiary referral center.

Intratympanic Steroid Use for Sudden Sensorineural Hearing Loss: Current Otolaryngology Practice.

Objective: To investigate the current practice of intratympanic steroid (ITS) injection for sudden sensorineural hearing loss (SSNHL) in the United Kingdom and link the data with data from the United States and continental Europe.

Methods: A survey of 21 questions was distributed to members of the British Society of Otology using an online survey platform via ENT UK. Data obtained from UK otolaryngologists (n = 171) were integrated with previously published data from other countries, including the United States (n = 63) and continental Europe (n = 908).

Clinical examination and management of the dizzy patient.

Dizziness is the commonest reason for a GP appointment over the age of 75 years and many dizzy patients will end up in hospital. This article introduces the range of vestibular disorders commonly seen in hospital practice with a symptom-based approach and discusses the range of treatments that might be considered.

The effect of electrode positioning on the ocular vestibular evoked myogenic potential to air-conducted sound.

Objective: To assess the effect of electrode position on the amplitude and latency of ocular vestibular evoked myogenic potentials (oVEMPs) produced by air-conducted (AC) sound with a view to optimisation of the recording paradigm.

Methods: Eight otologically normal subjects (16 ears) were stimulated by 500 Hz AC tone bursts at 95 dBnHL; oVEMP traces were recorded below the eye contralateral to the acoustic stimulation. Five independent oVEMP measurements were recorded with the active electrode in equally spaced positions in the infra-orbital plane relative to a reference electrode positioned 2 cm below the lower lid in the orbital midline.

Altered frequency dynamics of cervical and ocular vestibular evoked myogenic potentials in patients with Ménière's disease.

Objective: To measure the frequency dynamics of cervical and ocular vestibular evoked myogenic potentials in healthy subjects and patients with Ménière's disease.

Study Design: A prospective cohort study.

Setting: A university teaching hospital.

TRANSDUCER FIELD IMAGING USING ACOUSTOGRAPHY.

A common current practice for transducer field mapping is to scan, point-by-point, a hydrophone element in a 2D raster at various distances from the transducer radiating surface. This approach is tedious, requiring hours of scanning time to generate full cross-sectional and/or axial field distributions. Moreover, the lateral resolution of the field distribution image is dependent on the indexing steps between data points.

Feasibility study of complex wavefield retrieval in off-axis acoustic holography employing an acousto-optic sensor.

We propose and experimentally demonstrate a new method for complex-valued wavefield retrieval in off-axis acoustic holography. The method involves use of an intensity-sensitive acousto-optic (AO) sensor, optimized for use at 3.3 MHz, to record the acoustic hologram and a computational method for reconstruction of the object wavefield.

Intraoral radiographic findings in acne calcification: a case report.

The authors present a case report of a 52-year-old Hispanic female who presented for a routine dental exam at the Arthur A. Dugoni School of Dentistry in San Francisco. Incidental findings of multiple, calcified acne vulgaris lesions were noted in the soft tissues of the cheek that were viewed in the periapical radiographs.

Use of TissuePatchDural™ in the closure of an iatrogenic fistula following posterior semicircular canal occlusion surgery for intractable benign paroxysmal positional vertigo.

Benign paroxysmal positional vertigo (BPPV) is a common disorder caused by the dislocation of otoconia most commonly into the posterior canal. The primary symptoms are brief episodes of head-position related vertigo which may be accompanied by nausea and disequilibrium. BPPV is usually managed conservatively with excellent results, however in a small number of cases the symptoms can become persistent and incapacitating.

Emergency medical service providers' experience with family presence during cardiopulmonary resuscitation.

Objective: To describe emergency medical service providers' experiences with family member presence during resuscitation, and to determine whether those experiences are similar within urban and suburban settings.

Methods: We conducted a personally distributed survey of a convenience sample of urban and suburban emergency medical service (EMS) providers presenting to two Midwestern Emergency Departments. Providers were questioned as to their experiences with resuscitating patients in the presence of family members.

Bone marrow progenitors are not the source of expanding oval cells in injured liver.

Liver progenitor/oval cells differentiate into hepatocytes and biliary epithelial cells, repopulating the liver when the regenerative capacity of hepatocytes is impaired. Recent studies have shown that hematopoietic bone marrow (BM) stem/progenitor cells can give rise to hepatocytes in diseased/damaged liver. One study has reported that BM cells can transdifferentiate into liver progenitor/oval cells, but it has not been proven that the latter can repopulate the liver.
