Effects of parenteral papaverine and piracetam administration on cochlea following acoustic trauma.

Introduction: Noise exposure, the main cause of hearing loss in countries with lot of industries, may result both in temporary or permanent hearing loss. The goal of this study was to investigate the effects of parenteral papaverine and piracetam administration following an acoustic trauma on hearing function with histopathologic correlation.

Materials And Methods: Eighteen Wistar albino rats exposed to noise for 8 h in a free environment were included.

Investigation of neutrophil-to-lymphocyte ratio and mean platelet volume in sudden hearing loss.

Introduction: Several theories attempt to explain the pathophysiology of sudden hearing loss.

Objective: The objective of this study was to investigate the possible role of inflammation and atherothrombosis in sudden hearing loss patients through the neutrophil-to-lymphocyte ratio and mean platelet volume.

Methods: Study design - retrospective cross-sectional historical cohort.

Drug-induced sleep endoscopy versus Müller maneuver in patients with retropalatal obstruction.

Objective/hypothesis: This study aimed to compare application of the Müller maneuver (MM) and application of drug-induced sleep endoscopy (DISE) prior to surgery, in addition to MM, to further ascertain the location of an obstruction in the upper airway and whether the location would change the surgical treatment plan in patients with retropalatal obstruction.

Study Design: Prospective, clinical trial at a tertiary referral hospital.

Methods: This study included 39 obstructive sleep apnea patients who were recommended for surgical treatment.

Elevated neutrophil-to-lymphocyte ratio in Bell's palsy and its correlation with facial nerve enhancement on MRI.

Objective: The aim of this study was to investigate the role of inflammation and atherothrombosis in Bell's palsy (BP) by using neutrophil-to-lymphocyte ratio (NLR) and mean platelet volume (MPV), respectively, and to study their relations with the facial nerve enhancement on temporal gadolinium-enhanced magnetic resonance imaging (TGd-MRI).

Study Design: Case control study.

Setting: Tertiary health institution.

Elevated neutrophil-to-lymphocyte ratio in squamous cell carcinoma of larynx compared to benign and precancerous laryngeal lesions.

Background: Laryngeal carcinogenesis is a multifactorial process that has not been fully elucidated. Despite extensive research, reliable markers with diagnostic and prognostic value are still lacking. It was recently reported that an elevated preoperative neutrophil-to-lymphocyte ratio (NLR) may correlate with an increased risk of recurrence, tumor aggressiveness and poorer prognosis in various malignancies.

A new suggestion for the Epworth Sleepiness Scale in obstructive sleep apnea.

The aim of this study was to suggest a new cutoff score for the Turkish version of Epworth Sleepiness Scale (ESS) in the patients with obstructive sleep apnea. In this study, the data of 483 patients who were admitted to our clinic with the complaints of daytime sleepiness and witnessed sleep apnea were reviewed retrospectively. The correlation between ESS and polysomnography (PSG) findings were assessed, and cutoff score of the Turkish version of the ESS was investigated.
