OBJECTIVES/HYPOTHESIS: To determine salivary pepsin levels as a function of collection time. STUDY DESIGN: A prospective, case-control study. METHODS: We selected 57 patients with clinical symptoms and signs of laryngopharyngeal reflux who underwent 24-hour multichannel intraluminal impedance-pH (24h MII-pH) monitoring tests, and 12 control subjects without clinical symptoms and signs of laryngopharyngeal reflux. All subjects were instructed to collect saliva samples upon waking, 1 hour after ea

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

SOX2 copy number and mRNA expression were analysed to examine the clinical significance of SOX2 activation in HNSCC. Gene expression signatures reflecting SOX2 activation were identified in an HNSCC cohort. Patients with HNSCC were classified into two subgroups according to the gene expression signature: SOX2-high and SOX2-low. The clinical significance of SOX2 activation was further validated in two independent cohorts. Moreover, clinical significance of SOX2 activation in response to radiother

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

OBJECTIVE: To analyze patterns of central lymph node (LN) metastasis to specific compartments in the neck and predictive factors of contralateral paratracheal LN metastasis in patients who underwent prophylactic bilateral central LN dissection for papillary thyroid cancer (PTC). STUDY DESIGN: Prospective study. SETTING: Multitertiary centers. SUBJECTS AND METHODS: One hundred forty consecutive patients underwent total thyroidectomy and prophylactic bilateral central LN dissection for unilateral

Intraoral removal of proximal submandibular stones has several advantages over SMG resection. Based on our results, we suggest that our intraoral removal method be selected as the primary procedure for the removal of proximal submandibular stones rather than SMG resection.

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.

BACKGROUND: Additional high-quality evidence for predictors of peritonsillar abscess recurrence could lead to better-informed treatment decisions regarding tonsillectomy. METHODS: In this study, 172 patients, who had been diagnosed and treated for peritonsillar abscess, were evaluated at follow up. A retrospective review of medical records and a telephone survey were performed. The clinical characteristics analysed included underlying disease, laboratory findings and computed tomography findings

BACKGROUND: Human carbonyl reductase 1 (CBR1) plays major roles in protecting cells against cellular damage resulting from oxidative stress. Although CBR1-mediated detoxification of oxidative materials increased by stressful conditions including hypoxia, neuronal degenerative disorders, and other circumstances generating reactive oxide is well documented, the role of CBR1 under ionising radiation (IR) is still unclear. METHODS: The formalin-fixed and paraffin-embedded tissues of 85 patients with
