Epithelial-myoepithelial carcinoma (EMC) is a rare and low-grade malignant salivary gland tumor including epithelial and myoepithelial components. EMC frequently arises in the parotid gland but infrequently originates from the salivary glands of the nasal cavity. Here, we report the case of an EMC arising from the inferior turbinate, one of the most uncommon sites. A 60-year-old female patient presented with left nasal obstruction for several months, and PNS CT showed an about 4×1.4-cm-sized heterogeneously enhancing polypoid mass originating from the inferior turbinate of the left nasal cavity. After surgical treatment, the patient was diagnosed with EMC based on pathologic examinations including histopathological and immunohistochemical tests. We report a case of a patient with EMC in the inferior turbinate who was observed over 18 months without radiation therapy after successful wide excision. [ABSTRACT FROM AUTHOR]

Background and Objectives: Positional therapy is a therapeutic method for obstructive sleep apnea (OSA). However, little is known about the effectiveness of positional OSA treatment based on meta-analysis. Therefore, we undertook a review and meta-analysis of studies to assess the effect of positional therapy on OSA. Subjects and Method: We searched PubMed (Medline), OVID Medline, EMBASE, Cochrane Library, SCOPUS, KoreaMed, MedRIC, and KSI KISS using the key words "obstructive sleep apnea" and "positional therapy". To estimate the effect of positional OSA therapy, we analyzed the ratio of means (ROM) for pre- and post-treatment polysomnographic data including apnea-hypopnea index (AHI), lowest oxygen saturation, arousal index, and sleep efficiency. Results: Finally, twenty two studies from 21 papers were included in the meta-analysis. Positional therapy significantly decreased AHI by 54.1% [ROM, 0.459; 95% confidence interval (CI), 0.394 to 0.534] and increased lowest oxygen saturation by 3.3% (ROM, 1.033; 95% CI, 1.020 to 1.046). However, positional therapy did not significantly change arousal index (ROM, 0.846; 95% CI, 0.662 to 1.081) or sleep efficiency (ROM, 1.008; 95% CI, 0.990 to 1.027). Conclusion: Positional therapy significantly improves respiratory parameters including AHI and lowest oxygen saturation in patients with OSA. [ABSTRACT FROM AUTHOR]
