Prediction of a Difficult Airway Using the ARNE Score and Flexible Laryngoscopy in Patients with Laryngeal Pathology.

: The ARNE score was developed for the prediction of a difficult airway for both general and ear, nose and throat (ENT) surgery with a universal cut-off value. We tested the accuracy of this score in the case of laryngeal surgery and provided an insight into its effects in combination with flexible laryngoscopy. : This prospective pilot clinical study included 100 patients who were being scheduled for microscopic laryngeal surgery.

Impact of Sensorineural Hearing Loss during the Pandemic of COVID-19 on the Appearance of Depressive Symptoms, Anxiety and Stress.

Background: The incidence of hearing loss is constantly increasing and according to the World Health Organization, by 2050, 900 million people will suffer from hearing loss. The main Objective of the study was to determine the differences between the severity of the symptoms of stress, anxiety and depression in participants with varying degrees of sensorineural hearing loss during the COVID-19 pandemic. An additional aim was to examine the extent and manner in which protective face masks impact the communication of people with hearing loss.

COVID-19 caused hearing loss.

Purpose: The objective of this cross-sectional study was to determine if there is a potential link between COVID-19 infection and hearing loss.

Methods: The prospective study was conducted in the COVID Hospital Clinical Centre Niš, Serbia. We performed tonal audiometry and used a custom questionnaire and medical histories to determine the incidence of hearing loss in COVID-19 positive patients.

The Effects of Melatonin on Oxidative Stress Parameters and DNA Fragmentation in Testicular Tissue of Rats Exposed to Microwave Radiation.

Background: Microwaves from mobile phones are one of the environmental toxicants that are capable of compromising male fertility by inducing oxidative stress and apoptosis in the testes. Melatonin is a lipophilic tryptophan indole amine and a potent antioxidant.

Objectives: The aim of the study was to evaluate the effect of melatonin treatment on oxidative stress parameters and DNA fragmentation in the testicular tissue of rats exposed to microwave radiation (4 h/day).

Primary and salvage total laryngectomy. Influential factors, complications, and survival.

Purpose: In this retrospective study we analysed patients with advanced squamous cell carcinoma of the larynx and hypopharynx treated with primary total laryngectomy (PTL) between 1990 and 2007.

Methods: The patients were treated by classical PTL, radiotherapy 60-70 Gy, concomitant radio and chemotherapy (cisplatin and 5-fluorouracil) or salvage total laryngectomy (STL). They were followed up for 5 years and complications, survival, residual/recurrent disease and metastases were registered.

Head and neck cancer surgery in elderly: complications and survival rate.

The number of aged patients with head and neck cancer is increasing. The aim of this study was to evaluate the outcome of elderly patients with head and neck cancer undergoing surgery. Retrospective analysis of a series of 1509 consecutive patients separated in two groups regarding their age: younger than 70 and older than 70 years, with head and neck tumors treated surgically was performed.

Influential factors, complications and survival rate of primary and salvage total laryngectomy for advanced laryngeal cancer.

This is a retrospective review of patients with advanced malignant neoplasms of the larynx treated with total laryngectomy. 387 total laryngectomies for advanced squamous cell carcinoma of larynx performed in the period between 1995 and 2007 were analyzed. Primary total laryngectomy (PRT) was performed in 316 patients, while initial radiotherapy radiotherapy (60-70 Gy) and concomitant chemotherapy (cisplatin-5 fluorouracil) with radiotherapy were applied in totally 71 patients who later received salvage total laryngectomy (STL).

Stridor as initial clinical presentation of tracheal chondroma.

Chondromas are benign cartilaginous tumours that are uncommon in the head and neck region. Only few cases of chondroma have been reported in the trachea. We present a 70-year-old patient who presented clinically with severe dyspnoea requiring urgent tracheotomy.

Changes in auditory ossicles in rheumatoid arthritis: scanning electron microscopic study.

The aim of this study was to define the existence of surface changes on auditory ossicles caused by rheumatoid arthritis. The study comprised of nine pairs of auditory ossicles (mallei and incudes) from autopsy of patients with rheumatoid arthritis, and five pairs of ossicles from persons without RA, taken during autopsies. The specimens were studied with JEOL JSM 5300 type scanning electron microscope.
