Myeloperoxydase expression in the pathogenesis of nasal polyps.

Nasal polyps are benign mucosal protrusions that expand into the nasal cavity. There are no any etiological factors that may explain the pathogenesis of nasal polyps but currently inflammation continues to be the major factor. As a result of inflammation, neutrophils become activated and migrate to the inflammatory area and form their bactericidal effects by producing free oxygen radicals.

The effects of allergic rhinitis on growth, development and body mass indexes in school children.

Objective: The purpose of this study is to determine the frequency of allergic rhinitis (AR) in children and investigate if allergenic rhinitis demonstrated any effects on developmental growth levels and body mass indexes (BMI) in children.

Materials And Methods: 651 students, between 3-15 years of age who were randomly selected from four elementary schools located at Kartal, Istanbul were assessed according to symptoms and the presence of AR by nasal examination with the aid of a 0 degree 2.7 mm hand rigid endoscope.

[Infraorbitally located tuberculous lypmhadenitis: a case report].

Tuberculosis, which is one of the oldest diseases of the human kind, is again becoming an important health issue in recent years. Although mostly seen in lungs, it can also be localized in the lymph nodes, skin, meninges, spleen, surrenal tissues, which is referred to as extrapulmonary forms of tuberculosis. Tuberculous lymphadenitis is the most common clinical form of extrapulmonary tuberculosis and it is generally localized in cervical lymph nodes.

Role of the 30 degrees telescope in evaluation of laryngeal masses during direct laryngoscopy.

Visualization of enlarged laryngeal lesions is the most important factor in choosing a surgical technique, especially for partial surgery. For this reason standard microlaryngoscopy, a computed tomography (CT) scan of the larynx, and 30 degrees telescopic microlaryngoscopy were compared during evaluation of the laryngeal ventricul and sub-glottic area. The histopatholgoical findings of the specimens collected under each modality were simultaneously compared.
