Recent data suggest that IL-15 plays an important role in the pathogenesis of rheumatoid arthritis. In the present study, we hypothesized that elevated in the joints of rheumatoid arthritis, but not osteoarthritis, patients, IL-15 may exert its proinflammatory properties via the induction of IL-17, a cytokine known to stimulate synoviocytes to release(More)
This study evaluated the effectiveness of vitamins A, C, and E, with selenium, in the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL). This was a prospective, controlled study performed at a tertiary teaching and research hospital. Over a 32-month period, patients were treated with either our standard ISSNHL treatment regimen plus(More)
A 2-month-old female infant with respiratory distress, cyanosis and swallowing difficulties following birth was referred to our hospital by the pediatric clinic. Flexible fiber optic laryngoscopic examination of the patient revealed a red-purple smooth-surfaced mass inside the tongue base and vallecula. No additional features were identified by(More)
INTRODUCTION Various graft materials have been used to close tympanic membrane perforations. In the literature, there are few studies in pediatric populations comparing different graft materials. To our knowledge, there is no reported study that measured the thickness of the tragal cartilage in pediatric tympanoplasties. The tragal cartilage is not of(More)
Mycobacterium avium subspecies paratuberculosis (MAP) is suspected to be a causative agent in Crohn's disease. Recent evidence suggests that MAP can induce the expression of Matrix Metalloproteinases (MMPs), which are the main proteases in the pathogenesis of mucosal ulcerations in inflammatory bowel disease (IBD). Within the present study, we analysed(More)
Mycobacterium avium ssp. paratuberculosis (MAP) is the cause of Johne's disease, an inflammatory bowel disorder of ruminants. Due to the similar pathology, MAP was also suggested to cause Crohn's disease (CD). Despite of intensive research, this question is still not settled, possibly due to the lack of versatile mouse models. The aim of this study was to(More)
Aim. To compare the retinal nerve fiber layer (RNFL) thickness between women with polycystic ovary syndrome (PCOS) and healthy women. Materials and Methods. The study included 88 eyes of 44 women (group 1) with PCOS and 84 eyes of 42 healthy women (group 2). In all subjects, the RNFL and ganglion cell complex (GCC) thicknesses were measured by optical(More)
In head and neck surgery, penetrating neck injuries are uncommon. The neck contains many important structures, so such trauma can cause significant morbidity and mortality. A patient with penetrating neck trauma should be examined promptly in the emergency room. If possible, damaged tissue and organ fragments should be preserved carefully.
INTRODUCTION Knowledge of the site of obstruction and the pattern of airway collapse is essential for determining correct surgical and medical management of patients with Obstructive Sleep Apnea Syndrome (OSAS). To this end, several diagnostic tests and procedures have been developed. OBJECTIVE To determine whether drug-induced sleep endoscopy (DISE) or(More)
OBJECTIVES Laryngoceles are air-filled sacs which communicate with the laryngeal lumen. When filled with mucus or pus, they are called laryngomucoceles and laryngopyoceles, respectively. Transoral robotic surgery (TORS) is a new and remarkable technique that expands its usefullness in otorhinolaryngology. Conventional treatments for laryngoceles were(More)
