Association of Genotypes With Nasopharyngeal Carcinoma Risk.

Background/aim: The up-regulation of matrix metalloproteinase-9 (MMP-9) expression is a characteristic feature observed across various malignancies, including nasopharyngeal carcinoma (NPC). Nevertheless, the influence of MMP-9 genotype in the context of NPC remains underexplored. This study examined the implications of MMP-9 promoter rs3918242 genotypes on the susceptibility to NPC in Taiwan.

Clinical Outcomes of Severe Rhinosinusitis Complicated with Cavernous Sinus Syndrome.

Various diseases involving the cavernous sinus can cause a condition called cavernous sinus syndrome (CSS), which is characterized by ophthalmoplegia or sensory deficits over the face resulting from the compression effect of internal structure. While tumor compression is the most reported cause of CSS, statistical data on CSS caused by infections are limited. Its risk factors, treatment methods, and clinical outcomes are not well-documented.

Efficacy of Adjuvant Sublingual Immunotherapy After Septomeatoplasty.

Background: The efficacy of adjuvant sublingual immunotherapy (SLIT) in correcting structural problems in patients with allergic rhinitis (AR) caused by mite who have undergone septomeatoplasty (SMP) has not been studied.

Background: Sialolithiasis is one of the most common salivary gland disorders, most commonly affecting the submandibular gland. Submandibular sialolithiasis can be treated using non-invasive conservative measures and invasive treatments. Treatment selection was based on the ductal system anatomy and the size and location of the stones.

Bacteriology of Different Phenotypes of Chronic Rhinosinusitis.

Objectives: Chronic rhinosinusitis (CRS) reduces the health-related quality of life and subsequently causes a tremendous socio-economic impact. Although many studies have been conducted, few have identified a relationship between bacteriological characteristics and different phenotypes or endotypes. Therefore, this study aimed to elucidate the recent trends in bacterial cultures from different types of CRS in the Asian population.

Non-Homologous End-Joining Pathway Genotypes Significantly Associated with Nasopharyngeal Carcinoma Susceptibility.

Defects in the non-homologous end-joining (NHEJ) DNA repair pathway lead to genomic instability and carcinogenesis. However, the roles of individual NHEJ genes in nasopharyngeal carcinoma (NPC) etiology are not well-understood. The aim of this study was to assess the contribution of NHEJ genotypes, including (rs6869366, rs3734091, rs28360071, rs28360317, rs1805377), (rs828907, rs11685387, rs9288518), (rs5751129, rs2267437, rs132770, rs132774), rs7003908, and rs1805388, to NPC risk, with 208 NPC patients and 416 controls.

A Genome-Wide Association Study Identified Novel Genetic Susceptibility Loci for Oral Cancer in Taiwan.

Taiwan has the highest incidence rate of oral cancer in the world. Although oral cancer is mostly an environmentally induced cancer, genetic factors also play an important role in its etiology. Genome-wide association studies (GWAS) have identified nine susceptibility regions for oral cancers in populations of European descent.

Association of Genotypes With Oral Cancer Risk.

Background/aim: The over-expression of enhancer of zeste homolog 2 (EZH2) protein is found in oral cancer tissues. However, the genetic role of the enhancer of EZH2 in the etiology of oral cancer is unknown. The aim of this study was to evaluate the association of EZH2 genotypes with oral cancer risk among Taiwanese.

The Contribution of Flap Endonuclease 1 Genotypes to Oral Cancer Risk.

Background/aim: Flap endonuclease 1 (FEN1) is a critical protein in DNA repair, genomic stability, and carcinogenesis. Functional polymorphisms in FEN1 promoter -69G>A (rs174538) and 3'UTR 4150G>T (rs4246215), have been associated with the susceptibility to several cancers, including lung, breast, esophageal, gastric, liver, colorectal, and gallbladder cancer, as well as glioma, endometriosis, and leukemia. However, the contribution of FEN1 variant genotypes to oral cancer has never been examined.

The Changes in the Severity of Deep Neck Infection Post-UPPP and Tonsillectomy in Patients with OSAS.

The main aim of this study is to compare the incidence rate and severity of deep neck infection (DNI) in patients post-UPPP+ T (uvulopalatopharyngoplasty plus tonsillectomy) and without UPPP+ T. We utilized the data derived from the Longitudinal Health Insurance Database (LHID) of the National Health Insurance Research Database (NHIRD) in Taiwan from 1 January 2000 to 31 December 2012. Patients who had undergone combined UPPP and tonsillectomy were selected using National Health Insurance (NHI) surgical order.

Autologous Fat Plus Platelet-Rich Plasma versus Autologous Fat Alone on Sulcus Vocalis.

Sulcus vocalis is a frequent cause of glottic insufficiency that leads to incomplete vocal fold closure during phonation. Type II sulcus vocalis is defined as a partial defect of the lamina propria (LP). Treatment with fillers, such as fat or hyaluronic acid (HA), in the vocal folds is widely used, but the duration of effect is variable.

Esophageal Pressure and Clinical Assessments in the Gastroesophageal Reflux Disease Patients with Laryngopharyngeal Reflux Disease.

Laryngopharyngeal reflux disease (LPRD) might be associated with reflux symptoms, and its severity is correlated with the Reflux Symptoms Index. Diagnosis is often challenging because of a lack of accurate diagnostic tools. Although an association between LPRD and gastroesophageal reflux disease (GERD) exists, the extent to which esophageal pressure changes in patients with LPRD with GERD has been unknown.
