BACKGROUND/AIMS: The potential physiologic roles of Klotho in acute kidney injury (AKI) have recently been demonstrated in animal models. However, to date, there have been no human studies investigating the expression of renal Klotho in AKI. METHODS: We retrospectively collected biopsy specimens and clinical data of AKI patients between January 2001 and December 2012. Klotho expression was determined by immunohistochemical staining, and the clinical-pathological correlation was examined. RESULTS

OBJECTIVES/HYPOTHESIS: The aim of this study was to compare sinonasal-related quality of life (QOL) in patients treated by extended or transsellar endoscopic skull base surgery. STUDY DESIGN: Prospective data analysis. METHODS: Prospectively collected data from patients who underwent endoscopic skull base surgery between 2012 and 2017 were analyzed. Primary outcomes were preoperative Sino-Nasal Outcome Test-20 (SNOT-20) scores and then 1-month, 3-month, and 6-month follow-up. Comparative analysi

The aim of this study was to evaluate the effect of topical administration of onion (Allium cepa) extract on nasal cavity for treatment of allergic rhinitis (AR). BALB/c mice were sensitized by intraperitoneal injection of ovalbumin (OVA) and challenged with intranasal instillation of OVA with or without onion extracts for five times a week on 3 consecutive weeks. Allergic symptom score according to frequencies of sneezing, serum total and OVA specific immunoglobulin E (IgE) level, cytokine leve

The prevalence of olfactory and gustatory dysfunction was 24.2% in mild COVID-19 patients. All patients had hyposmia due to sensorineural olfactory dysfunction, which was confirmed using validated olfactory and gustatory evaluation methods and endoscopic examination. Olfactory and gustatory dysfunction may be characteristic indicators of mild COVID-19.

Obstructive sleep apnea (OSA) is caused by upper airway obstruction during sleep and increases risk for stroke and cardiovascular morbidity. It is also related to excessive daytime sleepiness and cognitive dysfunction in affected adults. Additionally, OSA also affects children, manifesting as growth retardation and neurobehavioral abnormalities. Continuous positive airway pressure (CPAP) therapy is the treatment of choice for moderate to severe disease in adults and in some of the pediatric popu

Objectives The aim of this study was to assess the sleep quality and sleep stability according to the severity of obstructive sleep apnea (OSA) by using questionnaires and cardiopulmonary coupling (CPC) analysis. Methods Two hundred and twenty‐one adults were evaluated using subjective sleep questionnaires, CPC parameters, and respiratory parameters measured during full‐night polysomnography. We measured the differences in the CPC parameters of each OSA group and the correlation between the apne

Although subjective olfactory function is significantly decreased in the OD group, the objective olfactory function was not significantly different. Moreover, olfactory training is effective in COVID-19 patients with OD.

BACKGROUND: Fungal rhinosinusitis (FRS) with mucosal invasion is not classified by the current criteria, and clinical reports on the topic are limited. The aim of this study was to present our 25-year experience on fungal balls with mucosal invasion that do not appear in the FRS classification. METHODS: Of 1318 patients who underwent endoscopic surgery with paranasal FRS between November 1994 and July 2019, 372 underwent mucosal biopsies. Medical chart and pathology review were performed on 13 p

We conclude that NSF was the key factor that led to olfactory impairment after endoscopic skull-base surgery.

Olfactory and gustatory dysfunctions are important initial symptoms of coronavirus disease 2019 (COVID-19). However, the treatment modality for these conditions has yet to be clearly established. Therefore, most physicians have been administering empirical treatments for COVID-19-associated olfactory dysfunction, including topical or systemic steroid supplementation and olfactory training. In this literature review, we summarize the clinical course and effects of various treatments currently bei

In order to investigate the density of seasonal incidence of mosquitoes, a vector of infectious diseases in Jeju region, this study collected mosquitoes using a Black light trap (BL) and Biogents' Sentinel 2 Mosquito Trap (BG), dividing the region into cattle sheds, habitats for migratory birds, and the downtown area, twice a month for 9 months from March through November 2018. Then, this study conducted identification and classification and checked for the presence of Flavivirus using reverse t
