The objective of this study was to investigate the roles of matrix metalloproteinases (MMP-2, MMP-9) and cyclooxygenase-2 (COX-2) in the pathogenesis of vocal fold polyps (VFPs). In this study, 20 VFPs and 8 normal vocal fold (VF) specimens were obtained from subjects undergoing surgery. Staining intensities were semiquantitatively assessed and(More)
OBJECTIVE The purpose of this study was to determine if free oxygen radicals (FORs) and antioxidant enzyme activities have some role in pathogenesis of otitis media with effusion (OME) in children with adenoid hyperplasia. METHODS Seventy-four patients were enrolled in three groups of this study. The study group (Group I) included 26 patients who had(More)
OBJECTIVE To investigate the relationship between development of laryngeal cancer and the presence of polymorphisms of the MnSOD Val16Ala, CAT-262 C < T and GPx1 Pro198Leu genes in a smoking population. PATIENTS AND METHODS Single nucleotide polymorphisms were determined in DNA from the peripheral blood erythrocytes of 48 heavy smokers (25 patients with(More)
Infectious mononucleosis (IM) is a rare cause of aplastic anemia in adults. We report of a patient in whom aplastic anemia, mucormycosis and aspergillosis complicated during the course of IM and successfully treated with liposomal amphotericin B. According to our searches in literature, we could not find a similar patient complicated and successfully(More)
OBJECTIVE The purpose of this study was to examine the changes in nitric oxide (NO) level in the nasal and paranasal sinus mucosa after exposure radiofrequency electromagnetic fields (EMF). STUDY DESIGN AND SETTING Thirty male Sprague-Dawley rats were randomly grouped as follows: EMF group (group I; n, 10), EMF group in which melatonin received (group II;(More)
BACKGROUND Allergic rhinitis is the most common chronic disease in the upper respiratory tract, requiring better diagnostic methodology to counteract its onslaught. The purpose of this study was to investigate the association between Toxocara seropositivity and allergic rhinitis. METHODS Sixty-four consecutive patients with allergic rhinitis and 61(More)
Eczematous external otitis, because of its basic allergic nature, tends to be chronic or recurrent. The purpose of our study was to investigate the association between allergic contact dermatitis and chronic eczematous external otitis. Sixty-six patients with eczematous external otitis and 48 healthy volunteers were included in this study. All the patients(More)
OBJECTIVES The present study aimed to investigate the effects of indomethacine, montelukast and methylprednisolone in management of experimental otitis media with effusion. METHODS Forty Wistar albino rats of which the weights ranged between 310 and 370 g were included in this study. Middle ear effusion was created by transtympanic histamine injection.(More)
Free oxygen radicals (FORs); have been implicated as important pathologic mediators in many diseases. Under physiological conditions FORs are part of normal regulatory circuits and neutralized by antioxidants, but an increased flux of FORs can cause tissue damage. Infections are one cause of increased FORs production. An important mechanism of tissue damage(More)
Many different methods have been described to obtain sinus culture from patients with chronic sinusitis. However, these methods presented limited information how they had prevented from the contamination with nasal flora. The purpose of this study is to demonstrate and describe a contamination-free technique to obtain culture from involved sinus during(More)
