Intraoperative Repair of Cerebrospinal Fluid Rhinorrhea in Skull Base Tumor Resection: A Retrospective Study of Acellular Dermal Matrix Versus Turbinate Flap.

Background: The acellular dermal matrix (ADM) and turbinate flap (TF) have been widely used in the reconstruction of skull base defects. However, owing to the lack of reported data, the therapeutic effects have been controversial. The purpose of the present study was to compare the effect of the ADM and TF on cerebrospinal fluid (CSF) rhinorrhea after nasal endoscopic resection of a skull base tumor.

Effect of High-Intensity Focused Ultrasound Versus Plasma Radiofrequency Ablation on Recurrent Allergic Rhinitis.

BACKGROUND High-intensity focused ultrasound (HIFU) and plasma radiofrequency ablation (PRA) have been used to treat recurrent allergic rhinitis (AR); however, there is a lack of literature comparing the efficacy of these 2 methods. We assessed and compared the therapeutic effects of HIFU and PRA on recurrent AR. MATERIAL AND METHODS We enrolled 66 patients with recurrent AR at West China Hospital of Sichuan University.

A disulfur ligand stabilization approach to construct a silver(i)-cluster-based porous framework as a sensitive SERS substrate.

An atomically-precise silver(i)-cluster-based three-dimensional (3D) framework (UJN-1) stabilized by a ditiocarb (diethyldithiocarbamate) ligand has been unveiled for the first time by self-assembly. UJN-1 is composed of both Ag clusters and Ag subunits, of which the Ag clusters are bonded with Ag subunits by sharing the ditiocarb ligand to form a microporous 3,4-connected topological framework. The chemically reduced nano-sized derivative of UJN-1 exhibits highly sensitive surface enhanced Raman scattering (SERS) towards 4-mercaptobenzoic acid (4-MBA) signal molecules, which is ascribed to the porosity as well as the distribution of abundant crystalline Ag active sites.

Application of high expansion degradable cotton in nasal bleeding model of dog.

Methods: Nasal endoscopic surgery was used to establish a dog model of nasal bleeding, and wound surfaces were filled with Merocel, Nasopore and HEDC, respectively.

Risk factors for lower respiratory tract infection in children with tracheobronchial foreign body aspiration.

The aim of this study was to determine the risk factors for lower respiratory tract infection (LRTI) in children caused by tracheobronchial foreign body aspiration (TFBA).A total of 351 patients were retrospectively reviewed; all patients were diagnosed with TFBA at West China Hospital of Sichuan University from 2015 to 2017. Univariate analyses and multivariate analysis were used.

A hydrogel directly assembled from a copper metal-organic polyhedron for antimicrobial application.

Here, we report the first example of a hydrogel directly assembled from a copper MOP by a facile ultrasonic procedure, and it exhibited excellent antibacterial activity towards Gram-negative and Gram-positive bacteria.

Acellular dermal matrix contributes to epithelialization in patients with chronic sinusitis.

Background: Nasal endoscopic surgery is widely used for nasal diseases, including sinusitis and tumors. However, scar hyperplasia, nasal irritation, scab, and nasal obstruction delay nasal mucosal recovery, with prolonged cleaning exacerbating the patient's financial burden. Here, we presented a novel approach for the treatment of nasal mucosal defects, termed acellular dermal matrix.

May the change of platelet to lymphocyte ratio be a prognostic factor for T3-T4 laryngeal squamous cell carcinoma: A retrospective study.

Background: Many blood markers have been shown to predict the recurrence and survival of various malignancies, but the effects of surgery on the body's inflammatory levels may cause changes in these inflammatory markers. Therefore, in this study, we assessed the relationship between changes in platelet to lymphocyte ratio (PLR) and survival and recurrence in patients with T3-T4 laryngeal squamous cell carcinoma (LSCC).

Methods: Data of patients with T3-T4 HSCC were reviewed.

[Traffic-related air pollution and allergic rhinitis].

Exposure to traffic-related air pollutants(TRAP)has been implicated in airway allergic diseases.Recent findings include epidemiologic and mechanistic studies that shed new light on the impact of TRAP on allergic rhinitis(AR)and the biology underlying this impact.These studies have found that oxidative stress induced by TRAP could affect the axis of epithelial cell-dendritic cell-T cell towards a T-helper 2 immune response,which is the major mechanism between TRAP and AR.
