Oral microbiota can alter cancer susceptibility and progression by modulating metabolism and inflammation. We assessed the association between the oral microbiome and lymph node (LN) metastasis in oral squamous cell carcinoma (OSCC). We collected a total of 54 saliva samples from patients with OSCC before surgery. LN metastasis was assessed based on postoperative pathological examination. We used QIIME2, linear discriminant analysis effect size (LEfSe), and PICRUSt2 methods to analyze microbial

OBJECTIVE: To compare the efficacy, relapse, and adverse effects between intralesional injection and mouth rinse of triamcinolone acetonide (TA) in patients with oral lichen planus (OLP). STUDY DESIGN: A randomized controlled study. SETTING: College medical center. SUBJECTS AND METHODS: Forty consecutive patients, who had been diagnosed with OLP, were recruited. Participants were randomly divided into 2 groups using intralesional injection or mouth rinse of TA. The severity of pain and burning s

Several studies have highlighted the diagnostic potential of salivary microRNA (miRNA) in head and neck squamous cell cancer (HNSCC). The purpose of this meta-analysis was to summarize published studies and evaluate the diagnostic accuracy of salivary miRNA in HNSCC detection. In this meta-analysis, we systematically searched PubMed, EMBASE, and Cochrane Library databases for studies on miRNA and HNSCC diagnosis. Pooled sensitivity, specificity, and diagnostic odds ratio (DOR) with a summary rec

BACKGROUND: The purpose of this study was to identify the prevalence of sialoceles and the risk factors associated with their formation after parotidectomy. METHODS: We performed a retrospective analysis of the data from consecutive patients who underwent partial superficial parotidectomy of parotid tumors. Demographic data, preoperative imaging results, operative variables, including tumor type, incision type, tumor size, and method of parenchymal disruption were assessed. RESULTS: Twenty-three

In patients with LPR, age seems to affect the subjective symptoms and resulting impact on quality of life but not the laryngeal findings. Furthermore, older patients are more likely not to respond to PPI therapy than younger patients.

There are little information on prevalence of obstructive sleep apnea syndrome (OSAS) and clinical features in the young military population. The purpose of this study was to estimate the prevalence of snoring and high risk of OSAS in young male soldiers in Korea and to identify the risk factors of OSAS. A total of 665 participants (aged 20-23 yr) who visited the Armed Forces Ildong Hospital for regular physical examination were enrolled. All participants completed the Berlin Questionnaire and u

INTRODUCTION: Seasonal variations of allergic diseases have been of great interest in clinical practice, but large-scale epidemiological data in the real world is lacking. METHODS: We conducted a nationwide, population-based, cross-sectional study using the Korean National Health Insurance claims database to examine the seasonalities of allergic rhinitis (AR), asthma, allergic conjunctivitis (AC), and atopic dermatitis (AD). In addition, we investigated the correlations between the monthly patie

TLR 2 and 4 were expressed in all the middle ear fluid samples of OME, but the mutations of TLR 2 and 4 were not detected. TLR 2 and 4 may play a vital role in the immunological responses of patients with OME.

BACKGROUND: The surgical extent and indication for treatment in patients with papillary thyroid microcarcinoma (PTMC) remain a controversial issue. The aim of this study was to investigate the predictive factor for contralateral occult carcinoma in patients with unilateral PTMC by preoperative ultrasonographic and pathological features. METHODS: Of the total patients who underwent thyroidectomy, 455 patients with PTMC confined to one unilateral lobe as diagnosed using preoperative ultrasonograph

Objectives. Toll-like receptors (TLRs) detect microbial infections and they can directly induce innate host defense responses. TLR 2 has been shown to be primarily involved in the recognition of peptidoglycans and lipoteichoic acid of gram positive bacteria. TLR 4 recognizes lipopolysaccharides and lipoteichoic acids from both gram-negative and grampositive bacteria. Both mutations lead a reduced capacity to elicit inflammation and they increase the risk for gram-positive and negative infections

OBJECTIVE/HYPOTHESIS: To evaluate the efficacy of spinal needle aspiration for symptom improvement in awake patients with epiglottic abscess (EA). STUDY DESIGN: Prospective randomized controlled study. SETTING: Tertiary center. SUBJECTS AND METHODS: Twenty-two patients who were diagnosed with EA were randomly allocated to group A (needle aspiration and antibiotics) or group B (antibiotics only). Patients' characteristics, laryngoscopic findings of epiglottic swelling and arytenoid swelling by sc
