E. N. T. Clinic에 내원하는 환자중 nasal symptoms을 호소하는 환자의 높은 비율에서 알레르기 질환이 있는 것을 느끼게 되며 특히 nasal cavity내에 오는 질환의 원인 중 알레르기가 놀라울 정도로 많은 것을 생각하면 이비인후과 영역에서의 알레르기에 대한 관심도 높다고 하겠읍니다. 일반적으로 비용증, 만성비염. 만성부비동염의 치료 방법으로는 약물요법과 수술요법을 병행하여 시행하는데 치료후 증상이 호전되다가 다시 계속적인 치료전의 증상이 재발되는 경우를 흔히 경험하게 된다. 특히 비용증 환자의 치료에서는 높은율의 재발을 경험하게 되는데 nasal symptoms을 일으키는 질환의 많은 원인이 allergy 라는데 착안하여 allegy symptoms은 호소하지 않았으나 비용증을 동반한 만성부비동염 환자에 수술 및 일반치료를 시행하였으나 얼마후 증상이 재현되어 Rinkels technique의 allergy test를 시행 하였다. 특정한 allergen에 양성을 보이지는 않았으나 일반적으로 nasal allergy의 많은 원인이 되는 House dust와 Mold groups의 allergen을 이용 (#2 ∼ #3 Solution)하여 계속적인 Desensitization을 시행함으로서 근치에 가까운 효과를 얻었기에 문헌고찰과 함께 보고하는 바이며 이러한 환자들에게 계속적인 allergy test상 양성반응을 보이지 않더라도 위의 방법을 적용하여 치료한 결과를 추후 발표드릴 것을 약속드립니다.

The present study investigates the clinical applicability of a new device which objectively measures nasal resonating vibration via piezoelectric vibratory sensor from 10 normal volunteers, 10 patients with definite hypernasality and 10 nasal polyposis patients. For the assessment of the hypernasality, the ratio of 'ng' to 'a' as well as that of 'mama' to 'papa' passages were used. For the evaluation of hyponasality, the ratio of nasal vibration post- to pre-induced cul-de-sac resonation was calculated. In the control group, the ratio of ng/a and mama/papa passages was larger than 8, while in the hypernasality group, the ratio was markedly lower. The vibratory signals of 'a' and 'ng' increased markedly in the control group and the hypernasality group after inducing cul-de-sac resonation, while in the hyponasality group, the change was minimal.

Eosinophilic chronic rhinosinusitis with nasal polyps (CRSwNP) is one of the most challenging problems in clinical rhinology. FZD5 is a receptor for Wnt5A, and its complex with Wnt5A contributes to activating inflammation and tissue modification. Nasal polyps and eosinophil/non-eosinophil counts are reported to be directly correlated. This study investigated the expression and distribution of FZD5, and the role of eosinophil infiltration and FZD5 in eosinophilic CRSwNP pathogenesis. The prognostic role of eosinophil levels was evaluated in seven patients with CRSwNP. Fifteen patients with CRS were classified based on the percentage of eosinophils in nasal polyp tissue. Methylated genes were detected using methylCpG-binding domain sequencing, and qRT-PCR and immunohistochemistry were used to detect FZD5 expression in nasal polyp tissue samples. The results showed that mRNA expression of FZD5 was upregulated in nasal polyps. FZD5 expression was significantly higher in nasal polyp samples from patients with eosinophilic CRSwNP than in those from patients with non-eosinophilic CRSwNP, as indicated by immunohistochemistry. Furthermore, inflammatory cytokine levels were higher in eosinophilic CRSwNP-derived epithelial cells than in normal tissues. In conclusion, FZD5 expression in nasal mucosal epithelial cells is correlated with inflammatory cells and might play a role in the pathogenesis of eosinophilic CRSwNP.

Kartagener`s syndrome is a clinical entity comprising a combination of situs inversus, bronchiectasis, and sinusitis or nasal polyposis. This syndrome is rare and is usually seen in a young age group. The syndrome is punctated by recurrent upper respiratory tract infection and pneumonia. This is a report of Kartagener`s syndrome found in 18 years old male and 21 years old female patients who were received surgical treatment of bronchiectasis. The male patient was performed right transposed lingular segmentectomy and lower lobectomy and female patient was perforated left transposed middle lobectomy and lower lobectomy. Both patients were discharged with good results.

BACKGROUND/OBJECTIVES: Epithelial-mesenchymal transition (EMT) is involved in not only cancer development and metastasis but also non-cancerous conditions. Hypoxia is one of the proposed critical factors contributing to formation of chronic rhinosinusitis or nasal polyposis. Wheatgrass (Triticum aestivum) has antioxidant, anti-aging, and anti-inflammatory effects. In this study, we analyzed whether wheatgrass has an inhibitory effect on the EMT process in airway epithelial cells. MATERIALS/METHODS: A549 human lung adenocarcinoma cells were incubated in hypoxic conditions ($CO_2$ 5%/$O_2$ 1%) for 24 h in the presence of different concentrations of wheatgrass extract (50, 75, 100, and $150{\mu}g/mL$) and changes in expression of epithelial or mesenchymal markers were evaluated by immunoblotting and immunofluorescence. Accordingly, associated EMT-related transcriptional factors, Snail and Smad, were also evaluated. RESULTS: Hypoxia increased expression of N-cadherin and reduced expression of E-cadherin. Mechanistically, E-cadherin levels were recovered during hypoxia by silencing hypoxia inducible factor (HIF)-$1{\alpha}$ or administering wheatgrass extract. Wheatgrass inhibited the hypoxia-mediated EMT by reducing the expression of phosphorylated Smad3 (pSmad3) and Snail. It suppressed the hypoxia-mediated EMT processes of airway epithelial cells via HIF-$1{\alpha}$ and the pSmad3 signaling pathway. CONCLUSION: These results suggest that wheatgrass has potential as a therapeutic or supplementary agent for HIF-1-related diseases.

Background and Objectives: In patients with asthma, increased obstruction and resistance of airway result in impairment in the generation of voice. Allergy and nasal polyposis, which are frequently observed in patients with asthma, are other factors that affect the vocal performance. Bronchodilators and steroids are commonly used in the treatment of asthma, and these agents also have been reported to be associated with voice changes. The aim of this study is to evaluate the voice quality in patients with mild to-moderate asthma by subjective and objective methods. Materials and Methods: A total of 36 patients with asthma established in the Department of Respiratory Medicine were included in this study. 23 were women and 13 were men, with a mean age of 51.7 years. The average duration of asthma was 77.0 months. All patients had mild-to moderate asthma. Acoustic and aerodynamic analyses were performed and the movements of the vocal cords were examined by videolaryngostroboscopy (VLS). Voice Handicap Index (VHI) and GRABS scales were used for subjective evaluations. Results: 50% of patients suffered from dysphonia and FO was 119.3${\pm}$23.7 Hz in male and 198.2${\pm}$18.4 Hz in female patients. There were no significant differences in average shimmer and NHR between females (4.90${\pm}$2.95% ; 0.1O${\pm}$0.04 dB) and males (4.64${\pm}$2.45% ; 0.20${\pm}$0.15 dB). However, the value of jitter was greater for females (2.60${\pm}$1.92%) than for males (1.21${\pm}$0.84%). The VHI score was above the normal limit in 35%, and VLS findings were shown diverse abnormality in 89% asthmatics from mucosal change to hyperfunction of supragottis and contact granuloma. But duration of illness and steroid dose did not correlate with these findings. Conclusion: Subjective and objective abnormality was shown in more than 50% of asthmatic patients. We suggest that persons who suffer from asthma should be examined for possible voice disorders by laryngologist. Additionally, appropriate medical care and voice therapy should be provided for those who have voice disorders associated with asthma.
