Chronic rhinosinusitis (CRS) is a multifactorial, heterogeneous disease characterized by persistent inflammation of the sinonasal mucosa and tissue remodeling, which can include basal/progenitor cell hyperplasia, goblet cell hyperplasia, squamous cell metaplasia, loss or dysfunction of ciliated cells, and increased matrix deposition. Repeated injuries can stimulate airway epithelial cells to produce inflammatory mediators that activate epithelial cells, immune cells, or the epithelial-mesenchymal trophic unit. This persistent inflammation can consequently induce aberrant tissue remodeling. However, the molecular mechanisms driving disease within the different molecular CRS subtypes remain inadequately characterized. Numerous secreted and cell surface proteins relevant to airway inflammation and remodeling are initially synthesized as inactive precursor proteins, including growth/differentiation factors and their associated receptors, enzymes, adhesion molecules, neuropeptides, and peptide hormones. Therefore, these precursor proteins require post-translational cleavage by proprotein convertases (PCs) to become fully functional. In this review, we summarize the roles of PCs in CRS-associated tissue remodeling and discuss the therapeutic potential of targeting PCs for CRS treatment.

The study has been carried out to investigate of the Allergic Rhinitis by referring to 87 literatures. The results were as follows; 1. In oriental medical science, Allergic Rhinitis is belong to the category of the 'BiGu'(鼻구) 'GuChe'(구체). The 'Gu'(구) of the BiGu means watery rhinorrhea, the 'Che'(체) of the GuChe means sneezing. 2. The cause of a disease summarize the weak of Lung, Spleen and Kidney, and invasion into the nasal cavity of PoongHan etc a wrong air. Sometimes the pathologial change appear PoongHan changeHwa(風寒化火), HwaYeol is hidden in the inside(火熱內伏). The contributing factors are found a season(spring, winter), an abnormal weather(運氣 : 少陰 少陽 陽明 司天, 歲金不及), an emotional stress, an external wound of the harmful air, a food allergens and fatigue, a contact of substances, a sunlight etc. 3. Predominant symptoms are watery rhinorrhea, sneezing and nasal obstruction.

Relapsing polychondritis (RP) is a rare autoimmune disorder of unknown etiology characterized by recurrent episodes of inflammation and the destruction of cartilaginous tissues, primarily involving the ear, nose, and the respiratory tract. Nasal chondritis is present in 24% of patients at the time of diagnosis and develops subsequently in 53% throughout the diseases progress. Progressive destruction of nasal cartilage leads to the characteristic flattening of the nasal bridge, resulting in the saddle nose deformity. In patients with RP, surgical management for saddle nose is carefully decided due to the disease relapsing characteristics. We present a RP patient with a saddle nose deformity who underwent reconstruction rhinoplasty with autologous costal cartilage grafting. At 6-month follow-up, the patient retained good esthetic results and showed neither complication nor relapse of RP.

Clinical and bacteriological observations on infectious atrophic rhinitis of swine were conducted in order to obtain some basic information for the clinical and immnnological control of the disease prevailing in the republic. Samples were collected from nasal cavities of 135 4~12 week old pigs from 12 herds and from turbinates of 199 slaughtering pigs from 14 swine herds to investigate the prevalence of Bordetella bronchiseptica and/or Pasteurella multocida in the nasal cavities of the pigs. On the examination of nasal swabs by cultural techniques and of gross lesion of snouts of slaughtering pigs, all the swine herds investigated were found to be affected by atrophic rhinitis and a total of 84 B bronchiseptica and 139 P multocida cultures were isolated from the nasal cavities of the pigs. Of the 199 slaughtering pigs, some 48% revealed gross pathological lesion typical of atrophic rhinitis and the prevalence of B bronchiseptica and P multocida were 27.6% and 46.7%, respectively. Biochemical properties, antimicrobial susceptibilities, serological characteristics and toxigenicity of the isolates of B bronchiseptica and P multocida were investigated.

Neuroblastomas are sometimes associated with abnormal constitutional karyotypes, but the XYY karyotype has been rarely described in neuroblastomas. Here, we report a case of an esthesioneuroblastoma in a boy with a 47, XYY karyotype. A 6-year-old boy was admitted to our hospital because of nasal obstruction and palpable cervical lymph node, which he first noticed several days previously. A polypoid mass in the right nasal cavity was detected through sinuscopy. Biopsy of the right nasal polyp was performed. Based on the result, the patient was diagnosed with a high-grade esthesioneuroblastoma. Nuclear imaging revealed increased uptake in both the right posterior nasal cavity and the right cervical IB-II space, suggesting metastatic lymph nodes. Cytogenetic analysis revealed a 47, XYY karyotype. Twelve courses of concurrent chemotherapy were administered. Three years after the completion of chemotherapy, the patient had had no disease recurrence. He manifested behavioral violence and temper tantrums, so we started methylphenidate for correction of the behavior.

A 10-year old female Yorkshire terrier with nasal discharge and swelling was referred to the local animal hospital. Abnormal mass of right nasal cavity was detected in physical examination and radiography. According to the radiographs of the head, there was an evidence of bony destruction in right nose. Oronasal fistula was detected in right maxillary canine teeth. After surgical excision, the sample of nasal mass was refereed to Pathology Department of Veterinary Medicine in Jeju National University. Grossly, the enlarged mass was soft and 3 ${\times}$ 3 cm in size. Histopathologically, the neoplastic mass was composed of tubular to tubulopapillary structures which were lined by single to 6~7 layers of cuboidal to ciliated columnar cells. These neoplastic cells showed invasive tendency to adjacent normal parenchyma. They had uniform, round to oval nuclei, cytoplasm with small vacuoles and indistinct cellular margin. The number of mitotic figures was varied in different areas, ranged from 0 to 4 per high power field. Necrotic foci and infiltration of inflammatory cells including neutrophils, lymphocytes, and plasma cells also presented in the mass. Immunohistochemically, the neoplastic cells demonstrated strong positive reaction for cytokeratin (CK) 18 but were negative for CK 7 and 8. Based on the gross, histopathology and immunohistochemistry, this mass was diagnosed as nasal adenocarcinoma originated from respiratory epithelium.

Obstructive sleep apnea (OSA) in children is a frequent disease for which optimal diagnostic methods are still being defined. Treatment of OSA in children should include providing space, improving craniofacial growth, resolving all symptoms, and preventing the development of the disease in the adult years. Adenotonsillectomy (T&A) has been the treatment of choice and thought to solve young patient's OSA problem, which is not the case for most adults. Recent reports showed success rates that vary from 27.2% to 82.9%. Children snoring regularly generally have a narrow maxilla compared to children who do not snore. The impairment of nasal breathing with increased nasal resistance has a well-documented negative impact on early childhood maxilla-mandibular development, making the upper airway smaller and might lead to adult OSA. Surgery in young children should be performed as early as possible to prevent the resulting morphologic changes and neurobehavioral, cardiovascular, endocrine, and metabolic complications. Close postoperative follow-up to monitor for residual disease is equally important. As the proportion of obese children has been increasing recently, parents should be informed about the weight gain after T&A. Multidisciplinary evaluation of the anatomic abnormalities in children with OSA leads to better overall treatment outcome.

Sinonasal Undifferentiated Carcinoma (SNUC) is a very rare, highly aggressive malignant tumor of the nasal cavity and paranasal sinuses. SNUC tends to present with advanced-stage disease, often with intracranial invasion. It requires an aggressive multimodality therapy that includes surgical resection. A cure rate of less than 20% is generally reported in the literature, with most patients dying within 1 year of onset of the disease. Three patients diagnosed as SNUC were treated at the Yeungnam University Medical Center between the years 2000 and 2003 were analyzed retrospectively. All patients presented with the disease very advanced. The three cases were given chemotherapy or chemotherapy with radiotherapy. Two patients died of the disease, surviving only 6 and 11 months following treatment, respectively. We did a follow-up on just the one remaining case with incomplete controlled disease for 27 months. The overall prognosis of SNUC is very poor. We consider that more intensive multimodality therapies are recommended for all patients with SNUC.
