BACKGROUND Nasotracheal intubation typically comprises three distinct stages: (i) nasopharyngeal intubation; (ii) direct laryngoscopy to identify the vocal cords; and (iii) the passage of the tracheal tube into the trachea. The aim of this study was to identify and compare the cardiovascular responses associated with each of these stages. METHODS Seventy-five ASA I or II patients, aged 16-65 ...

Nasopharyngeal carcinoma is a common malignancy in Southeast Asian countries, and genetic background is a well-known component of the complexity underlying its tumorigenic process. We have mapped a nasopharyngeal carcinoma susceptibility locus to chromosome 4p15.1-q12 in a previous linkage study on nasopharyngeal carcinoma pedigrees. In this study provided in this communication, we screened all...

OBJECTIVE To evaluate the shapes and sizes of nasopharyngeal airways by using cone-beam computed tomography and to assess the relationship between nasopharyngeal airway shape and adenoid hypertrophy in children. METHODS Linear and cross-sectional measurements on frontal and sagittal cross-sections containing the most enlarged adenoids and nasopharyngeal airway volumes were obtained from cone-...

RATIONALE Thyroid metastasis from nasopharyngeal carcinoma is rare. Metastasis of nasopharyngeal carcinoma to the thyroid gland with subsequent metastatic abdominal lymph nodes hasn't been reported before. We want to share our experience about the treatment choice. PATIENT CONCERNS A 27-year-old man was diagnosed with nasopharyngeal nonkeratinizing carcinoma in August 2004. In March 2013 he u...

Introduction: Nasopharyngeal carcinoma (NPC) is a rare malignancy in children. Nasal obstruction, otitis media with effusion, pain in the ear, hearing problems, and unusual neck mass are among the signs and symptoms of this malignancy.   Case Report: We report the case of a 13-year-old girl with NPC who later developed acute lymphoblastic leukemia (ALL) through the course of her disease. To our...

Aim: The aim of the study was to evaluate incidence asymptomatic COVID-19 disease in pregnant women withrectal and oropharyngeal/nasopharyngeal swab compare efficacy two samples.Material Method: This prospective cohort included 234 who had undergoneplanned cesarean section between May 7 September 24, 2020 obstetrics unit a tertiary care center, Ankara,Turkey. swab, rectal placental, amniotic fl...

The open-mouth and closed-mouth nasopharyngeal airway radiographs of 53 children, whose symptomatology score was concordant with nasopharyngeal airway obstruction that may be due to adenoidal enlargement, were taken and, for each radiograph, nasopharyngeal airway/soft palate (NA/SP) ratio was measured and graded using the method of Cohen and Konak. According to the statistical analysis, since c...

PURPOSE Nasopharyngeal carcinoma is prevalent in southern China and Southeast Asia, with distinct geographic and ethnic distribution. One candidate susceptibility locus has been identified at 4p11-14, with the associated candidate gene(s) not identified yet. This study investigated the role of ubiquitin carboxyl-terminal hydrolase L1 (UCHL1) in nasopharyngeal carcinoma pathogenesis. EXPERIMEN...

BACKGROUND Several studies have suggested that claudin proteins, which are the main components of tight junction structures, are related to the regulation of cell polarity and cell differentiation. METHOD To explore the expression profiles of the tight junction proteins claudin-2, - 5, - 8 and - 9 in nasopharyngeal carcinoma, IHC (immunohistochemical analysis), Western blot and real-time PCR ...

BACKGROUND No studies have examined the relationship between COX-2 8473T>C polymorphism and the risk of nasopharyngeal carcinoma in Chinese population. MATERIAL AND METHODS 296 patients with nasopharyngeal carcinoma and 300 age and gender-matched healthy controls recruited were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Cancer risk associated w...
