Evaluation of the Effect of Sampling Strategy on Test Results in the COVID-19 Pandemic.

Background: The oronasopharyngeal (ONP) sampling phase is critical in the diagnosis of infection during the coronavirus disease-2019 (COVID-19) pandemic. In this study, the aim is to investigate the effect of the standardized operational team in the sampling unit on test results and repetitions.

Methods: Patients who applied to the Adult Pandemic Polyclinic between August 2020 and October 2021 and whose ONP samples were taken for Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) Polymerase Chain Reaction (PCR) test were included in the study.

Effects of platelet-rich fibrin and dexamethasone on nerve regeneration after acute facial-nerve injury.

Background: Acute facial-nerve injury.

Objective: To investigate the effects of platelet-rich fibrin (PRF) and dexamethasone on nerve regeneration.

Materials And Methods: Thirty-six rats were randomly divided into six groups.

Effect of perinatal and postnatal thiamine deficiency on auditory pathway of the Wistar-Albino rats.

Objective: In this study, we created an animal model to demonstrate the effects of thiamine on the hearing pathways of new-borns during pregnancy and lactation by inducing a dietary thiamine deficiency in the mother.

Methods: The study included 16 female Wistar albino rats. The animals were separated into four groups and provided the appropriate amounts of dietary thiamine according to their groups during pre-pregnancy, pregnancy, and lactation periods.

Otorhinolaryngological, audiovestibular and swallowing manifestations of patients with Niemann-Pick disease Type C.

Objectives: The aim of this study is to evaluate audiovestibular and swallowing impairment of patients with NPC.

Methods: Audiovestibular and swallowing evaluation were performed on patients with Niemann-Pick disease type C (NPC) at Hacettepe University between 20013 and 2015 prospectively. Pure-tone audiometry (PTA), Auditory Brain stem response (ABR), Flexible endoscopic evaluation of swallowing (FEES) test and posturography were done.

Traumatic multiple lower cranial nerve palsy: a case report and review of the literature.

Lower cranial nerve palsy, also known as Collet-Sicard syndrome, is a fairly rare pathology characterized by unilateral palsy of the IX-X-XI-XII cranial nerves. We report a multiple cranial nerve palsy developing after a head trauma that might have been considered negligible. A 16-year-old boy was admitted with swallowing and articulation problems and difficulty lifting one shoulder after a head trauma suffered during a football match.

Pharyngocutaneous fistula after salvage laryngectomy.

Conclusion: Preoperative chemoradiotherapy (CRT) was associated with a significantly higher rate of pharyngocutaneous fistula (PCF).

Objective: PCF is the most frequent complication following total laryngectomy. Although organ-preserving radiotherapy (RT) or CRT offer good locoregional control, many patients still require salvage laryngectomy.
