Inadvertent perioperative hypothermia and surgical site infections after liver resection.

Background: In the overall surgical population, inadvertent perioperative hypothermia has been associated with an increased incidence of surgical site infection (SSI). However, recent clinical trials did not validate this notion. This study aimed to investigate the potential correlation between inadvertent perioperative hypothermia and SSIs following liver resection.

Endobronchial removal of a metallic needle using a flexible diagnostic bronchoscope and biopsy forceps. A case report from Djibouti.

Foreign body removal is a challenging procedure. Firstly we have to identify properly the foreign body and the position of the obstruction. Secondly we have to choose the proper removal equipment and finally the appropriate method of patient ventilation during the procedure.

Wireless Power Transfer and Energy Harvesting: Current Status and Future Prospects.

The rechargeable battery is the conventional power source for mobile devices. However, limited battery capacity and frequent recharging requires further research to find new ways to deliver power without the hassle of connecting cables. Novel wireless power supply methods, such as energy harvesting and wireless power transfer, are currently receiving considerable attention.

Short-term effect of relatively low level air pollution on outpatient visit in Shennongjia, China.

Background: Many cities in China are currently experiencing severe air pollution due to modernization. Previous studies investigating the effects of air pollutants exposure were particularly conducted in severe air polluted area and studies in low pollution areas were sparse.

Methods: To quantitatively assess the short-term effects of ambient air pollutants (PM, PM, SO, NO, CO and O) on outpatient visits in low pollution area, we conducted a time-series analysis from Jan 1, 2015 to Dec 31, 2016 in Shennongjia, China.

Primary observation of early transtympanic steroid injection in patients with delayed treatment of noise-induced hearing loss.

Approximately 5% of the population worldwide suffer from varieties of noise-induced hearing loss (NIHL). Prevention and early identification remain the best methods of approaching NIHL. Over the years, numerous methods of improving the outcome in patients presenting with NIHL have been evaluated; however, these are far from sufficient.

[Hair cells apoptosis and the activation of P53 protein in intensive impulse noise induced cochlear lesion].

Objective: To explore the pattern of hair cell injury and expression of P53 apoptosis protein in intensive impulse noise injured cochlear hair cells in guinea pigs.

Methods: Twelve adult guinea pigs were exposed to a series of 40 pairs of impulse noise (2 second intervals) at the intensity of 168 dB (SPL). Animals were terminated at 3, 6 and 12 hours after noise exposure, respectively.

Early transtympanic steroid injection in patients with 'poor prognosis' idiopathic sensorineural sudden hearing loss.

Objective: The present trial is aimed to evaluate the effectiveness of early transtympanic steroid injection in patients with 'poor prognosis' idiopathic sensorineural sudden hearing loss (ISSHL).

Methods: Seventy-six patients, diagnosed as having ISSHL with 'poor prognosis', were randomized into a transtympanic group and a control group. Thirty-nine patients received conventional steroid treatment and 37 patients received 4 courses of additional transtympanic injections of methylprednisolone 7 days after conventional steroid treatment.

Functional and structural changes in the chinchilla cochlea and vestibular system following round window application of carboplatin.

OBJECTIVE: In chinchillas, moderate doses of carboplatin administered systemically selectively destroy inner hair cells and type I vestibular hair cells; however, it is unclear whether this unique damage pattern persists if carboplatin is applied directly to the cochlea, how quickly the damage develops and what cell death pathways are involved. STUDY DESIGN: To address these questions, carboplatin (5 mg/ml, 50 µl) was applied to the round window. RESULTS: Carboplatin caused a rapid decline in distortion product otoacoustic emissions, significantly increased compound action potential thresholds and caused massive inner hair cell loss and less severe outer hair cell loss.

Intratympanic administration of methylprednisolone reduces impact of experimental intensive impulse noise trauma on hearing.

Conclusion: The present findings demonstrated that intratympanic methylprednisolone (MP) reduces the impact of impulse noise trauma on hearing and in part preserves the hair cells from death 1 h after exposure to intensive impulse noise.

Objective: To examine the treatment efficiency of intratympanic MP (IT-MP) with different methods of administration on cochlear injury induced by exposure to intensive impulse noise.

Materials And Methods: Fifty-five guinea pigs were assigned into six groups and exposed to intensive impulse noise, i.
