We present the case of a 33 year-old man from a village of the north-eastern part of central Anatolia admitted to the otolaryngology department of Yeditepe University Hospital with right facial asymmetry and pain on the right ear. A tick of the genus Hyalomma was observed in the external auditory canal of the right ear and it was removed with fine cup forceps under otomicroscopy. We are of the opinion that in patients presenting with sudden acute ear pain and facial palsy, the ear canal should be examined to exclude an infestation by ticks.

Objectives/hypothesis: Verbal fluency deteriorates with normal aging, but is much more severe in Alzheimer's Disease (AD). Verbal functions were analyzed to find differences between normal aging subjects in patients with mild cognitive impairment (MCI), and in patients with early and moderate stages of AD. This study measured the verbal response time in patients with AD, MCI, and in control subjects

Study Design: This study measured the verbal response time in patients with AD, MCI, and in control subjects

Methods: Fifteen patients with MCI, 15 patients with early AD, 8 patients with moderate AD, and 15 subjects for controls were included in the study.

Hypertrophy of inferior turbinate is a common condition, especially with nasal septum deviation. Sometimes, the cause of hypertrophy of inferior turbinate can be fibro-osseous lesions. Benign, rare, and non-aggressive fibro-osseous neoplasms such as ossifying fibroma can affect paranasal sinuses.

Background: The molecular mechanisms in malignant transformation of laryngeal mucosa are unknown; many clinical and pathological factors affect prognosis. We investigated a possible correlation between overexpression of p53, proliferating cell nuclear antigen (PCNA), and c-erbB-2, and the clinicopathologic features of laryngeal squamous cell carcinoma (SCC) and clarify their prognostic value.

Material/methods: Thirty-three men with laryngeal SCC participated; all underwent primary surgery or surgery plus radiotherapy between 1999 and 2004 at our department.

Paragangliomas are rare benign neuroendocrine tumors derived from the extra-adrenal paraganglia of the autonomic nervous system. Here, we described a new case of a 75-year-old woman with paraganglioma arising in the middle and posterior cranial fossa with extended destruction of the skull base and clivus. She was admitted to our department with the complaint of severe respiratory distress due to vocal cord paralysis.

Nitric oxide (NO) plays an important role in the regulation of upper respiratory function. Patients with untreated allergic rhinitis (AR) have an increased level of NO in the nasal cavity compared to normal individuals. We aimed to investigate serum levels of arginase and NO metabolites nitrite/nitrate in patients with AR during the symptomatic period.

Objective: To evaluate the autonomic nervous system in vasomotor rhinitis patients using heart rate variability parameters.

Patients And Methods: The heart rate variability parameters (SDANN, SDNN, SDNN index, RMSSD, pNN50, triangular index) of 26 patients with vasomotor rhinitis were compared with those of 25 control subjects.

Results: The decrease in the SDANN and SDNN index in the vasomotor rhinitis patients is statistically significant.

Schwannoma is a benign neoplasm originating from schwann cells of the peripheral nerve sheath, and its occurrence in the nasal cavity and paranasal sinuses is rare. We present a case of nasal schwannoma originating from the left nasal cavity, accompanied by bilateral nasal polyposis. A 66-year-old man presented with complaints of progressive left nasal obstruction, hyposmia, and headache.

Background: The purpose of this study was to investigate whether polymorphism of N-acetyltransferase 2 (NAT2) genotypes are associated with the risk of laryngeal squamous cell carcinoma (SCC).

Methods: The study group consisted of 45 white patients with laryngeal SCC (42 men, with a mean age of 54 years [range, 37-70 years] and three women, with a mean age of 47 years [range, 32-55 years]) and 104 control subjects (68 men and 36 women; mean age, 50 years; range, 28-73 years). All of the patients were primarily treated with surgical intervention.

Hypothesis: Glutathione and glutathione-related antioxidant enzymes are involved in the metabolism and detoxification of cytotoxic and carcinogenic compounds as well as reactive oxygen species. Reactive oxygen species generation occurs in prolonged relative hypoperfusion conditions such as in aging. The etiology of presbycusis is much less certain; however, a complex genetic cause is most likely.

Reactive oxygen species including hydroxyl radicals, superoxide anions and hydrogen peroxide which are produced by activated granulocytes play an essential role in many biochemical processes and diseases. Oxidant-mediated tissue damage may be important in the development of chronic sinusitis. The aim of this study was to investigate the serum levels of antioxidant vitamins and elements in 24 children (14 boys and 10 girls, age range: 7-12 years, mean age: 9.

Objectives: We investigated the effect of mometasone furoate on mucociliary clearance in patients with perennial allergic rhinitis.

Patients And Methods: The study included 25 patients (16 females, 9 males; mean age 30 years; range 18 to 50 years) with perennial allergic rhinitis. Mometasone furoate (nasal spray) was administered at a dose of 2 puffs (100 microgr) to each nostril daily for a month.
