OBJECTIVE The objective of this study was to analyze the circumstance, demographic features, clinical findings, and complications of caustic ingestion in relation to the type and amount of caustic substance. STUDY DESIGN The authors conducted a retrospective cohort study in a tertiary medical center. METHODS The authors reviewed medical records from(More)
Allergic, inflammatory, and immune responses carried out by eosinophils are regulated by the cross talk between activatory and inhibitory signals. While much data has been obtained on activatory signals, inhibitory receptors on these cells have received scant attention. Therefore, we screened the surface of human peripheral blood eosinophils for inhibitory(More)
OBJECTIVE To describe our experience with sclerosing treatment of lymphangiomas in the head and neck region by intralesional injections of OK-432. STUDY DESIGN Case series. METHODS Patients with the diagnosis of a macrocystic-type cervical lymphangioma were treated by one to three intralesional injections of OK-432 (0.01 mg of OK-432/1 mL of(More)
OBJECTIVE The aim of this study was to evaluate the routine use of packing or local hemostatic agents in endoscopic sinus surgery (ESS). METHODS Packing and/or hemostatic agents were used only when necessary in 100 consecutive adult ESS patients in a tertiary academic hospital. Necessity for packing the nose after excessive bleeding was analyzed in(More)
Idiopathic sudden sensorineural hearing loss (SSNHL) represents a frequently encountered otological disease of unknown etiology. In recent years, several inherited risk factors have been found in the pathogenesis of vascular diseases. In the present study, we determined whether specific polymorphism or the combination of polymorphisms in folate-dependent(More)
CONCLUSIONS C-reactive protein (CRP) levels may predict the extent of acute rhinosinusitis disease in the computed tomography (CT) scans, as well as the specific symptom severity. High levels may direct the physician to change the treatment. OBJECTIVE To establish tools to define 'high risk' patients suffering from acute rhinosinusitis. METHODS Patients(More)
PURPOSE Endoscopic endonasal surgery (EES) has become the standard practice in sinonasal and anterior skull base surgery. The purpose of this manuscript is to describe experience using a new technology-the image guided navigation system (IGNS)-in complex cases undergoing EES. The advantages and disadvantages of computer aided surgery are discussed. (More)
Histamine is a key mediator of allergic inflammation, primarily through competitive antagonism of binding to H1 receptors. In this issue, Weller and Maurer report that the H1 antagonist desloratadine possesses mast cell-stabilizing properties when challenged in an IgE-dependent or -independent fashion. Thus, desloratadine provides benefits that are(More)
Hemangioendothelioma is a vascular tumor of endothelial cell origin. It may involve bone or soft tissues and can behave like a benign or a malignant tumor. In the literature there are several case reports on the involvement of the head and neck region, but only three cases of temporal bone involvement, all of them in adults. A 3-year-old child, complaining(More)
