Purpose: The aim of this study is to develop and apply the critical pathway to the nasal bone fracture patients and to elucidate its effect. Methods: Critical pathway (CP) sheet and questionnaire were developed by a team approach. Critical pathway were applied to 30 nasal bone fracture patients (CP group) from June 2001 to November 2001. Length of hospitalization, cost for hospitalization and bed turnover rate of CP group were compared to those of the 30 patients who had same disease entities and treated by conventional regimen (control group). Results: Length of hospitalization in the CP group (4.20 day) were significantly shorter than that of control group (6.21 day). Mean cost for hospitalization of the CP group (492,106 won) were significantly lower than that of control group (678,376 won). Bed turnover rate in CP group (2.5) were higher than that of control group. The patients satisfaction for the medical personnel, explanation regarding operation procedure, therapeutic operation fee, and length of hospitalization were all affirmative. Conclusion: Critical pathway that we developed for nasal bone fracture definitely improved the quality of treatment and lowered cost of medical service. Furthermore, other critical pathways should be developed for another facial trauma patients.

There is much confusion in the field of Rhinitis regarding how to best measure disease severity objectively, Therefore, we aimed to establish a new adequate scoring system for Rhinitis, that should be based on comparison analysis of various scoring systems. We report as follows. We researched for data relating to severity scoring systems for rhinitis in Entrez PubMed from 1995 to 2005 and in Kiss Kstudy. Results and Conclusions: Properties of severity scoring systems were validity, sensitivity of change and ease of use. The essential items of severity scoring systems were subjective symptoms. The criterion of severity were divided into subjective symptoms and complication and Quality of Life. Intensity items are nasal obstruction, rhinorrhea, sneezing, itching, Postnasal drip, nasal mucosa swelling, nasal mucosa color, complication. Subjective symptoms is difficulty of Life. The significant items of severity scoring system are nasal symptoms. The whole score does with the maximum 30 scores. As it were, we assumed nasal symptoms accounted for around 80% of each total score, with complication and difficulty of Life representing 20%.

Purpose: To evaluate the radiotherapy treatment outcome of patients in stage IE and IIE nasal natural killer/T-cell lymphoma. Materials and Methods: From August 1999 to August 2009, 46 patients with stage IE and IIE nasal natural killer/T-cell lymphoma were treated by definitive radiotherapy and chemotherapy. 33 patients were treated with chemotherapy followed by radiotherapy (CT + RT) and they received 50.4 Gy in 28 fractions. 13 patients were treated with concurrent chemoradiotherapy (CCRT) and they received 40 Gy in 20 fractions. Results: The median follow-up period was 4.6-137.6 months (median, 50.2 months) for all patients. The 4-year overall survival was 68.6% and 4-year disease free survival (DFS) was 61.9%. The 4-year locoregional recurrence free survival was 65.0%, and 4-year distant metastasis free survival (DMFS) was 66.2%. For patients treated with CT + RT, 15 patients (45.5%) achieved complete response after chemotherapy, and 13 patients (39.4%) achieved partial response. 13 patients (81.8%) achieved complete response after radiotherapy, and 6 patients (18.2%) achieved partial response. For patients treated with CCRT, 11 patients (84.6%) achieved complete response, and one patient (7.7%) achieved partial response. In univariate analysis, presence of cervical lymph node metastasis was only significant prognostic factor for DFS and DMFS. Conclusion: This study did not show satisfactory overall survival rate and disease free survival rate of definitive radiotherapy and chemotherapy for stage IE and IIE nasal natural killer/T-cell lymphoma. For patients with cervical lymph node metastasis, further investigation of new chemotherapy regimens is necessary to reduce the distant metastasis.

Fibrous dysplasia(FD) of the bone is a slowly progressive, benign disease of unknown cause where normal architectures are replaced with fibrous and osteoid tissue. FD of the maxilla usually manifests as a bony enlargement with painless swelling and bone deformity, contouring to facial asymmetry. The lesion may involve the nasal fossae, orbits, or alveolus bone, causing diverse functional disturbance. Treatment options range from shaving to total maxillectomy and reconstruction depending on the presenting symptoms. Shaving, partial maxillectomy and maxillary sinus formation was performed in 5 patients with fibrous dysplasia in the past 2 years. Follow up period ranged from 1 month to 11 months. Aesthetic appearance, CT findings, and relief from symptoms were compared. In all patients, facial asymmetry was restored to symmetry and nasal obstructive symptoms were improved. With this procedure, expansion of the lesion will be controlled until puberty, preventing the development of new functional disturbances. After puberty, no further treatment can be anticipated due to the growth arrest inherent to the disease.

Extranodal Natural Killer (NK)/T-cell lymphoma, nasal type, is a subtype of non-Hodgkin lymphoma, strongly associated with Epstein-Barr virus. Extranodal NK/T-cell lymphoma mostly affects the nasal cavity and there has been no report of the disease's occurrence at the base of tongue. Here we report a case of 43-year-old man who presented with a diffuse ulcerative lesion at the base of tongue. Because the patient had oral bleeding, tracheostomy and lingual artery ligation was performed via a transcervical approach to control bleeding and protect the upper airway. We performed a deep biopsy through the lateral pharyngotomy approach, and finally, the patient was diagnosed with extranodal NK/T-cell lymphoma, nasal type. We report this rare case of extranodal NK/T cell lymphoma at the base of tongue with a literature review.

Purpose: The purpose of this study was to compare the contamination level of uniforms with nasal colonization of Staphylococcus aureus before and after the clinical practice of nursing students. Methods: This study was a survey research, conducting microbial culture by smearing the front surface and the pockets of uniforms, and the nasal cavity both before and after clinical practice on 70 nursing students. For the analysis, descriptive statistics, chi-square test, paired t-test were used for statistical analysis using SPSS 19.0. Results: The contamination level of uniforms increased more significantly after clinical practice on the front surface (p=.008) and pockets (p=.031) than before clinical practice, and Staphylococcus aureus, and Enterobacter aerogenes were detected. Conclusion: Through the results above, it is believed that it is reasonable to do the laundering of clinical uniforms of nursing students once a week. Because it is possible to disseminate disease germs with the contamination of clinical practice uniforms in a hospital environment, it is necessary to offer education for the laundering of uniforms with appropriate management.

The present study was carried out to investigate the pathogenicity and pathogenesis of wild rats(Rattus norvegicus), trapped in nature, intranasally infected with Aujeszky's disease virus(ADV/NYJ-1-87) by histopathology, immunohistochemistry and in situ hybridization(ISH). Fifteen rats inoculated intranasally were roughened haircoat, anorexia, listlessness, and depression second day after inoculation, and three rats died in 66-72 hours. Eight rats showed severe pruritus at the face that was accompanied by frequent face-washing movements of the forelegs, and then became violent and spasmodic for an hour or until they died. Four rats slowly recovered after showing mild clinical signs of the disease. Microscopic lesions in infected rats were characterized by meningitis, perivascular round cell infiltration, focal gliosis, and neuronal degeneration and necrosis. And intranuclear inclusion bodies were frequently detected in the cerebral cortex and medulla. Positive reaction to ADV by immunohistochemistry and ISH were detected in the following areas : trigermimal ganglion, brain, tonsil, nasal mucosa, spleen, lung and liver. The result has suggested that ADV intranasally infected in wild rats is followed by replication in epithelial calls of nasal mucosa and tonsil, then invade local lymph nodes by way of the lymphatics. It is also believed that the virus invades bipolar olfactory cells and trigerminal ganglion; and then spread into central nervous system.

To investigate the etiology, pathogenicity and virological properties of NYJ-1-87 strain of Aujeszky's disease virus (ADV) that was isolated from the diseased piglet in Korea, the virus at $10^{6.0}TCID_{50}/0.1ml$ was inoculated intranasally and subcutaneously into 30 to 35 days-old piglets. Results obtained through the experiments were summarized as follows. 1. Ten of the infected piglets were clinically observed for 15 days. On the 2nd day post-inoculation(pi), the signs of pyrexia, anorexia and convulsion were noted. On the 4th to 7th days pi, nervous signs of incoordination and intermittent spasm were shown in the most of piglets, and one out of 5 piglets infected intranasally was died with severe nervous signs at the 7th day pi. The signs became relieved on the 8th day pi and all of remainder were completely recovered on the 13th to 14th days pi. 2. In hematological study, prominent decrease in the number of total leukocyte and lymphocyte was shown in the ADV-infected piglets on the 6th day pi. On the 8th day pi, the cell numbers were slightly increased and returned to normal level on the 10th day pi. 3. Viral excretion of the ADV-inoculated piglets was examined by swabbing of nasal and oral cavities, and rectal feces. During the periods of the 3rd to 11th days pi, the virus was excreted intermittently from nasal and oral cavities, and rectal feces. The nasal excretions were shown the highest virus concentration of $10^{5.2}TCID_{50}/0.1ml$ at the 5th day pi. 4. Recovery of the inoculated virus from various organs of the piglets that were died or experimentally slaughtered was attempted, and the virus was isolated from the tissues of brain and tonsil by the cultured cell-inoculation method. The highest recovery rate was noted in the tonsil. By indirect immunofluorescence antibody assay using ADV-monoclonal antibody, the viral antigens were detected in tissues of spleen and liver as well as brain and tonsil on the 7th to 9th days pi. The virus was not isolated from blood and the tissues of lung and kidney throughout the experiments. 5. Titers of virus neutralizing antibody in the piglets experimentally infected with ADV became increased after the 6th to 9th days pi in both of intranasal and subcutaneous inoculation showing the highest titers of 64 to 128 on the 29th day pi. When the antibody levels were measured by radial immunodiffusion enzyme assay, the reactive diameter was enlarged to be positive after the 4th to 6th days pi in both of intranasal and subcutaneous inoculation showing the largest diameter of 13 to 14mm on the 29th day pi.
