BACKGROUND: Patients who suffer a cardiac arrest from trauma rarely survive, even with aggressive resuscitation attempts, including an Emergency Department (ED) thoracotomy. Emergency Preservation and Resuscitation (EPR) was developed to utilize hypothermia to buy time to obtain hemostasis before irreversible organ damage occurs. Large animal studies have demonstrated that cooling to tympanic membrane temperature 10°C during exsanguination cardiac arrest can allow up to 2 hours of circulatory arrest and repair of simulated injuries with normal neurologic recovery...

INTRODUCTION: Results of fat graft myringoplasty are often reported with only short-term follow-up. Audiological results are less commonly reported, as well as long-term follow-up results. MATERIALS AND METHODS: One hundred consecutive patients scheduled for fat graft myringoplasty were included in a prospective cohort study. Clinical and audiological outcomes were assessed at six weeks and one year postoperatively. RESULTS: Perforation sizes ranged from 0...

High Alt Med Biol 00:000-000, 2017.-The extent of altitude-related middle ear disorders in children native to high altitudes is unclear. This study examined middle ear pathophysiology in two groups of children living in high-altitude Ecuadorian Andean communities by investigating middle ear pressure (MEP), tympanic membrane compliance (TMC), and ear canal volume (ECV) using tympanometry, and by otological examination...

In orthopteran insects, a complex tibial organ has evolved to detect substrate vibrations and/or airborne sound. Species of New Zealand weta (Anostostomatidae) with tympanal ears on the foreleg tibia use this organ to communicate by sound, while in atympanate species (which communicate by substrate drumming) the organ is unstudied. We investigated the complex tibial organ of the atympanate ground weta, Hemiandrus pallitarsis, for vibration detection adaptations. This system contains four sensory components (subgenual organ, intermediate organ, crista acustica homolog, accessory organ) in all legs, together with up to 90 scolopidial sensilla...

The objective of the present study was to characterize the epidemiological variants of tympanosclerosis and the effectiveness of the surgical treatment of the patients presenting with this condition. We have undertaken the analysis of the results of 1965 surgical interventions on the patients suffering from different forms of chronic otitis media (COM) performed during the period from 2009 till 2014 with a view to determining the frequency of tympanosclerosis (TSC). In 542 cases, it proved possible to evaluate the intraoperative findings, stages and methods of reconstructive surgery, the anatomical and functional outcomes and effectiveness of the intervention...

Modification of sweating could be due to changes in activated sweat gland density (ASGD) and/or activated sweat gland output (ASGO). The present study determined regional and inter-ethnic differences in ASGD and ASGO during passive heating between tropical natives (African, n=22) and temperate natives (Republic of Korean, n=25). Heat load was carried out by immersing the half body into a hot water bath for 30min. Tympanic temperature (Tty) and skin temperature (Ts) were measured. Mean body temperature (mTb) was calculated...

OBJECTIVE: Intimate partner violence against women is a major health problem in most nations, but to date, there has been little awareness of the extent or seriousness of this issue in Jordan. Forensic medical practitioners play a significant role in diagnosing, evaluating and reporting these cases. The Jordanian judicial system is dependent on forensic reports. This study aims to assess the role of forensic medicine in evaluating the physical injuries sustained by women who are abused by their husbands...

Aim of the present study is to evaluate the long term results of ossiculoplasty using titanium clip prosthesis. A retrospective analysis with prospective follow-up has been done including for all patients who had a Clip-PORP implanted between the years 2002-2013. Following this, audiometric hearing results were measured with clinical examination including otoscopy and quality of life evaluation using Glasgow benefit inventory. 48 patients (51 ears, 29 men, 19 women, average age 44.1 years) received followed up after an average duration of 6...

INTRODUCTION: Long-term space flight induces a near visual acuity change in approximately 50% of astronauts. In some crew members, postflight cerebrospinal fluid (CSF) opening pressures by lumbar puncture are as high as 20.9 mmHg who demonstrated optic disc edema. CSF communicates through the cochlear aqueduct to affect perilymphatic pressure and tympanic membrane motion. We hypothesized that 50 mmHg of lower-body negative pressure (LBNP) during 15° head-down tilt (HDT) would mitigate elevations in internal jugular vein cross-sectional area (IJV CSA) and intracranial pressure (ICP)...

This manuscript intends to review types, pathogenesis, associated risk factors, and potential methods of prevention and treatment of the retraction pockets in adults and children. The importance of retraction pockets (RP) lies in loss of original histological and anatomical structure which is associated with development of ossicular chain erosion, cho¬lesteatoma formation and potentially life threatening complications of cholesteatoma. The trans-mucosal exchange each gas in the middle ear (ME) is towards equalizing its partial pressures with the partial pressure in the environ¬ment...

INTRODUCTION: Boric acid, which has antiseptic and acidic properties, is used to treat external and middle ear infections. However, we have not found any literature about the effect of boric acid powder on middle ear mucosa and inner ear. OBJECTIVE: The purpose of this study is to investigate possible ototoxic effects of boric acid powder (BAP) on cochlear outer hair cell function and histological changes in middle ear mucosa in a rat animal model. METHODS: Twenty healthy, mature Wistar albino rats were used in this study...
