Cabazitaxel's ototoxicity: An animal study and histopathologic research.

Introduction: Chemotherapeutic agents can have both serious side effects and ototoxicity, which can be caused by direct toxic effects or by metabolic derangement by the agents. Cabazitaxel (CBZ) is a next-generation semi-synthetic taxane derivative that is effective in both preclinical models of human tumors that are sensitive or resistant to chemotherapy and in patients suffering from progressive prostate cancer despite docetaxel treatment. The primary aim of this study is to investigate the ototoxicity of CBZ in a rat model.

A Role for Mast Cell-Mediated Antibodies in the Formation of Cholesteatoma and Cholesteatoma-Induced Bone Erosion.

The study aimed to evaluate the effects and relationships between mast cells in the matrix, mast cell enzymes tryptase and chymase, epithelial proliferation, microvascular density, and bone destruction in cholesteatoma. Thirty-five biopsies diagnosed with cholesteatoma and seven healthy skin tissues taken from the retro-auricular region for control were evaluated. Immunohistochemical studies were performed with CD117, CD34, Ki-67, chymase, and tryptase antibodies, in a single session for all cases and the control group.

A New Biomarker in Differentiation of Mucosal Chronic Otitis Media from Squamous Chronic Otitis Media: The Systemic Immune-Inflammation Index (SII).

The Systemic Immune-inflammation Index (SII) is a new biomarker based on the number of neutrophils, platelets, and lymphocytes in the Complete blood count, and is shown as diagnostic and prognostic in many diseases. Mucosal or Squamous COM differentiation is necessary preoperatively in chronic otitis media patients. The purpose of this study was to test the predictive value of inflammation markers to predict the differentiation of Mucosal COM and Squamous COM.

Ototoxicity of Triclosan: A Rat Model Study.

Objective: Triclosan is utilized as an antibacterial factor in many industrial products. Although there are many toxic features of triclosan in the literature, there is no study on the effect of triclosan on hearing. The purpose of this study is to determine the effect of triclosan on hearing in rats.

Is the combined use of ultrasonography (USG) and fine needle aspiration biopsy (FNAB) safe in parotis masses? Retrospective comprehensive comparison of 123 cases.

Objectives: The purpose of the study was to compare final pathology results with ultrasonography (USI) and fine needle aspiration biopsy (FNAB) results in parotis masses.

Methods: A total of 123 patients with primary parotis mass who applied to our center between 2010 and 2020 were selected for the study. Among these, 100 patients with preoperative USI, preoperative FNAB, and postoperative final pathology were included in the study.

Cochlear and vestibular involvement in children with IgA vasculitis.

Unlabelled: In this study, our purpose is to evaluate cochlear and vestibular function in juveniles with IgA vasculitis using audiometry, distortion product otoacoustic emissions, and cervical vestibular evoked myogenic potential (cVEMP) tests. Forty children diagnosed with IgA vasculitis from the pediatry clinic and 40 age- and sex-matched healthy children were evaluated with distortion product otoacoustic emissions, audiometry, and cVEMP test in a tertiary hospital. The audiometry average values for both ears of the IgA vasculitis group and the control subjects were compared, and as a result, median 4.

Comparison of the Healing Effect of Nasal Saline Irrigation with Triamcinolone Acetonide Versus Nasal Saline Irrigation alone in COVID-19 Related Olfactory Dysfunction: A Randomized Controlled Study.

There is no routinely determined treatment for olfactory dysfunction because of COVID-19. Saline irrigation and nasal corticosteroid treatments are safe and inexpensive methods, and have low side effects. In our study, we argue that saline nasal irrigation and topical corticosteroid treatment can be used in the treatment of patients with olfactory loss in all areas of rhinology.

Olfactory Cleft Opacification in COVID-19 Related Smell Loss: CT Findings and Correlation With Objective Testing.

Objectives: Besides the common symptoms of the coronavirus disease 2019 (COVID-19) including fever, shortness of breath, and cough, a "sudden loss of smell" has recently been added as a diagnostic symptom. The relationship between paranasal sinus computed tomography (PNS CT) and sudden loss of smell in COVID-19 was examined.

Materials And Methods: Two groups were selected for the study, the COVID-19 and the control groups.

New Approach for Endoscopic Endonasal Transsphenoidal Pituitary Surgery: Modified Nasoseptal Rescue Flap.

Introduction: Endoscopic endonasal approach has become popularly preferred for pituitary surgery in recent years. In this study we described a new technique which is developed by the first author and which is modified from The Rivera-Serrano "salvage" flap approach. With this new technique the septum morbidity was completely prevented and a wider and more comfortable vision was provided for the operation.

Congenital Deficiency of Alar Cartilage.

Alar cartilage anatomically determines the size, position, and shape of the nose type. It is also effective in the respiratory function of the nose. The structure of alar cartilage differs from person to person.

Vestibular involvement of PFAPA syndrome.

Objective: PFAPA syndrome is derived from the initials of the English words of the findings that make up the syndrome ("Periodic Fever", "Aphthous Stomatitis", "Pharyngitis", "Adenitis"). This study aims to evaluate the vestibular system in patients with PFAPA syndrome by the cVEMP test and to give a general review of PFAPA syndrome in light of current literature.

Methods: In this prospective study, 30 patients aged 4-6 who were diagnosed with PFAPA in a tertiary pediatrics clinic, between January 2016 and February 2020 and 30 children of the same age group who applied to a tertiary otorhinolaryngology clinic for other reasons and proven to have no hearing or vestibular problems were included and in addition to routine physical examination, electromyographic activity of the sternocleidomastoid muscle surface was measured.

Broad, Recurrent Nasal Dermoid Cyst: A Challenging Task.

Nasal dermoid sinus cyst is a rare congenital midline anomaly. The embryological origin is different from the dermoid cysts seen in other parts of the face. Nasal dermoid sinus cysts constitute 1% to 3% of all dermoid cysts and 11% to 12% of head and neck dermoid cysts.

The Effect of Nasal Steroid and Antihistamine Use on Total Oxidative Stress and Antioxidant Status in the Treatment of Allergic Rhinitis.

Introduction: The purpose of this study is to determine the post-treatment levels of total oxidant status (TOS) and total antioxidant status (TAS), that are increased due to pathophysiology, and to compare those with pre-treatment levels in allergic rhinitis patients. Among 84 patients clinically diagnosed with allergic rhinitis, 31 patients were started only on nasal steroid treatment (mometasone furoate), and 53 patients were started on nasal steroid and oral antihistamine treatment (mometasone furoate + rupatadine fumarate 10 mg). Blood samples were taken from the patients at the first examination and at post-treatment month 1.

Rhinoliths: Analysis of 24 Interesting Forgotten Foreign Body Cases.

Rhinoliths are petrified masses formed by accumulation of endogenous or exogenous salts around a nidus. Although rarely formed by the body, the most common cause is foreign bodies forgotten in the nose at childhood. Rhinoliths are rare and have been reported as a single case report in the literature.

Long-term management of patients with PFAPA syndrome.

Objective: To evaluate the long-term treatment results of patients with PFAPA syndrome and to determine their need for tonsillectomy.

Materials And Methods: The clinical characteristics, treatments and long-term results of 16 patients admitted to the Pediatric and Otorhinolaryngology Clinic between 2015 and 2019 were retrospectively analyzed.

Results: Twelve male and four female patients were examined between 1.

A new and simple test for diagnosis and prognosis in children with otitis media with effusion: cVEMP.

A typical vestibular stimulated myogenic potential (VEMP) response depends on suitable sound transfer from the middle ear to inner ear. This transfer is degraded at various degrees in otitis media with effusion (OME). In cases where the effusion is reduced by treating the OME, response to VEMP test can be obtained In this study we aimed to compare preoperative and postoperative VEMP values of children who were applied ventilation tube for OME and to compare these values and VEMP values of healthy children.
