Background Exposure to cigarette smoking (CS) is a major risk factor for airway inflammation. However, little known about the effects of CS exposure on eosinophilic rhinosinusitis with nasal polyps (ERSwNPs). Histopathological and molecular studies were performed investigate its using murine model ERSwNPs. Methods Mice assigned one following four groups (n = 8 each group): control group, (CS group), ERSwNP (ERS ERSwNPs exposed + group). changes investigated various stains, including...
Background and Objectives: Pediatric chronic rhinosinusitis (CRS) significantly affects children’s quality of life learning abilities. This study aimed to evaluate the postoperative outcomes in pediatric patients who underwent functional endoscopic sinus surgery (FESS) for CRS.Methods: A retrospective review was conducted on FESS CRS at 11 university hospitals. The inclusion criteria were under 20 years old with bilateral disease operated between January 2005 December 2021. data collected...
Background & aims Nasal obstruction caused by nasal septal deviation is very bothersome and, therefore, can affect the patient’s emotional state. However, little known about effect of (NSD) on neuropsychiatric aspects patients. Therefore, this study to verify higher incidence anxiety, depression, and migraine in patients diagnosed with NSD compared general populations using big data. Methods This retrospective cohort collected subjects from Korean National Health Insurance Service (NHIS)...
This study was designed to evaluate the normal development of nasal septum in Koreans using sagittal MRI for valuable clinical information on septal procedures.Two hundred eighty patients who had their whole visualized midline view were selected among 3,904 with brain from January, 2004 December, 2006 at Dankook University Hospital. The a history surgery or trauma excluded. Following parameters are calculated and analyzed: lengths bony cartilage dorsum cartilage-nasal bone overlap, total...
Cluster analyses on inflammatory markers of chronic rhinosinusitis (CRS) in Asians from multicenter data are lacking. This study aimed to identify the endotypes CRS Koreans and evaluate relationship between clinical parameters.Nasal tissues were obtained patients with controls who underwent surgery. The investigated by measuring interleukin (IL)-5, interferon (IFN)-γ, IL-17A, IL-22, IL-1β, IL-6, IL-8, matrix metalloproteinase-9, eotaxin-3, eosinophil cationic protein, myeloperoxidase (MPO),...
Little is known about alternative treatment options for rhinosinusitis (RS). We aimed to evaluate the efficacy of low-level laser therapy (LLLT) RS in experimentally induced rabbit models RS. A total 18 rabbits were divided into four groups: a negative control group (n = 3), an without 5, positive group), with natural recovery and irradiation laser-treated group). Computed tomography histopathological staining performed each group. mRNA protein expression levels local cytokines (IFN-γ,...
In Korea, tree pollens are known to be prevalent in spring, grass summer and weed autumn. However, few studies have revealed their seasonal specificity for allergic rhinitis symptoms. An ARIA (Allergic Rhinitis its Impact on Asthma) classification of was recently introduced clinical validation has not been well proved. The aim this study evaluate the allergens validate with conventional perennial (SAR/PAR) classification.Two hundred twenty six patients were included study. classified...
Limited information is available regarding strain-related differences in mouse models of allergic rhinitis induced by Dermatophagoides farinae (Der f1). In this study, we compared between two strains and determined the optimal dose Der f1 for models.Forty-eight mice were assigned to following six groups (n=8 per group): group A (control, BALB/c), B f1-sensitized BALB/c, 25 µg), C 100 D C57BL/6), E C57BL/6, F µg). Allergic inflammation was with alum sensitization, followed an intranasal...
Tobacco smoking (TS) has been known as one of the most potent risk factors for airway inflammatory diseases. However, there a paucity information regarding immunologic alteration mediated by TS in patients with chronic rhinosinusitis nasal polyps (CRSwNP). To identify effect TS, we harvested human tissue samples (never smoker: n=41, current n=22, quitter: n=23) and analyzed expression epithelial-derived cytokines (EDCs) such IL-25, IL-33, thymic stromal lymphopoietin. The expressions Th2...
Limited understanding exists regarding clinical distinctions between influenza A/H3N2 and A/H1N1 subtypes, particularly in primary health care. We conducted a comparative analysis of symptomatic characteristics subtypes Korea. This retrospective study analyzed medical records patients who presented with positive test results for influenza-like illness (rapid diagnostic test; RIDT) during the H3N2-dominant 2016-2017 H1N1-dominant 2018-2019 seasons. Symptomatic manifestations, contact history,...
Obstructive sleep apnea (OSA) is characterized by recurrent occurrences of partial or complete collapse the upper airway during sleep, leading to shallow breathing pauses. These repeated disruptions can result in intermittent hypoxia, hypercapnia, hyperactivity sympathetic nervous system, and fragmented patterns. Left untreated, OSA have significant health implications, including various symptoms serious consequences. Positional a subtype where severity events significantly higher supine...
Objectives Predicting the need for surgical treatment among patients with chronic rhinosinusitis (CRS) is challenging. The delta neutrophil index (DNI) has been proposed as a useful laboratory marker of immature granulocytes, which indicates infection or severe inflammation in several diseases. This study evaluated DNI an early predictor surgery CRS. Methods A total 117 diagnosed CRS were enrolled this retrospective and observational study. Medical records, including symptoms data, WBC...
Abstract Most patients who undergo open rhinoseptoplasty do not develop any wound at the transcolumellar incision site. However, some require care immediately post-operation. Dressing is difficult to perform in columellar region because of location. Here, we report 2 cases as a complication rhinoseptoplasty. A patient developed mild dehiscence after primary rhinoseptoplasty, whereas another partial skin necrosis revision operation. We applied DuoDERM Extra Thin dressing (ConvaTec Group,...
We analyzed the relationship between chronic rhinosinusitis (CRS) and incidence of head neck cancers (HNCs) in a Korean adult population. This retrospective cohort study included data from National Health Insurance Service database. Adjustments were made to minimize risk variables for sex, age, diabetes, hypertension, dyslipidemia, rhinitis two groups. The primary endpoint was newly diagnosed HNC January 2009 December 2018.
