Arsenic related hearing loss in miners.

Purpose: Arsenic is a toxic metalloid that carries number of potential risks to human health, although there is little evidence of the ototoxic effect of arsenic. The aim of this study was to identify the relationship between arsenic exposure and hearing loss by measuring blood arsenic concentrations and hearing among miners.

Materials And Methods: This research is a retrospective case control study.

Pediatric Tracheotomy: A 5-Year Experience in Düzce University Medical Faculty.

Objective: Tracheotomy is one of the oldest surgical procedures. Pediatric tracheotomy indications have changed in recent decades. Currently, tracheotomy is performed because of prolonged intubation, upper airway obstruction, neuromuscular, and craniofacial anomalies instead of acute airway infections.

Evaluation of middle ear pressure in the early period after adenoidectomy in children with adenoid hypertrophy without otitis media with effusion.

Objective: Our aim was to analyze the changes in middle ear pressure in the early period after adenoidectomy in children with adenoid hypertrophy without otitis media with effusion.

Methods: This prospective, descriptive study was performed on 64 patients (with normal tympanic membranes and tympanograms) undergoing adenoidectomy or adenotonsillectomy. All patients were operated by single experienced team using curettage technique.

The effect of duration of nasal obstruction on mean platelet volume in patients with marked nasal septal deviation.

Nasal obstruction is a common cause of marked nasal septal deviation. It is related strongly with hypoxia. Hypoxic conditions increase mean platelet volume levels.

When should automatic Auditory Brainstem Response test be used for newborn hearing screening?

Objectives: The aim of this study was to investigate the referral rate and when automatic Auditory Brainstem Response (aABR) should be used for newborn hearing screening.

Methods: The present study enrolled 2933 healthy full-term infants and 176 infants with perinatal risk factors. Hearing screening using Transient Evoked Otoacoustic Emissions (TEOAEs) was performed in newborns for the first time 5 days after birth except perinatal risk factors infants.

The effect of 2100 MHz radiofrequency radiation of a 3G mobile phone on the parotid gland of rats.

Purpose: We aimed to evaluate the effect of 2100 MHz radiofrequency radiation on the parotid gland of rats in short and relatively long terms.

Material And Methods: Thirty Wistar albino rats were divided into four groups. Groups A and B served as the control groups (for 10 days and 40 days, respectively), and each group included six rats.

A comparison of the effects of solvent and noise exposure on hearing, together and separately.

The objective of the present study was to assess the effects of occupational exposure to noise and organic solvents on hearing loss in bus and truck plant workers. Our case control study contained 469 workers from a bus and truck plant divided into three groups. The first group contained workers exposed to only noise; the second group contained workers exposed to both noise and mixture solvents at a permissible level; and the third group included workers exposed to permissible levels of solvents.

Role of electrical stimulation added to conventional therapy in patients with idiopathic facial (Bell) palsy.

Objective: The aim of this study was to determine the efficacy of electrical stimulation when added to conventional physical therapy with regard to clinical and neurophysiologic changes in patients with Bell palsy.

Design: This was a randomized controlled trial. Sixty patients diagnosed with Bell palsy (39 right sided, 21 left sided) were included in the study.

The use of glass ionomer cement in the reconstructıon of the dorsal L-strut: an experımental study on rabbıts.
