Integrating electrochemical pretreatment with microalgae treatment for nitrogen and phosphorus removal and resource recovery from swine wastewater.

This study integrates electrochemical pretreatment with microalgae (Scenedesmus obliquus) treatment to enhance nitrogen and phosphorus removal and resource recovery from swine wastewater. By optimizing electrochemical and microalgae treatment conditions, the dilution factor and the hydraulic retention time for microalgae treatment were reduced to 5 times and 7 days, respectively. Under the optimized operational conditions, removal efficiencies of total nitrogen and ammonia could reach over 89 %and 96 %,respectively, and the removal efficiency of total phosphorus was over 99 %.

Evaluation of post-surgical stability in skeletal class II patients with idiopathic condylar resorption treated with functional splint therapy.

Purpose: To assess postsurgical stability of mandibular advancement combined with orthodontic treatment, following functional splint therapy, in patients with idiopathic condylar resorption (ICR).

Patients And Methods: Sixteen patients who were treated with functional splint therapy followed by orthognathic surgery combined with orthodontic treatment between 2010 and 2017 were included in this retrospective study. The primary outcome variable was skeletal stability, measured on the y-axis to point B (y-axis-B).

A Retrospective Cohort Study of Risk Factors for Descending Necrotizing Mediastinitis Caused by Multispace Infection in the Maxillofacial Region.

Purpose: Descending necrotizing mediastinitis (DNM) has been the most common life-threatening complication of multispace infection (MSI) in the maxillofacial region owing to the lack of a timely diagnosis and treatment. We assessed the clinical characteristics and diagnosis of odontogenic MSI and evaluated the risk factors for DNM caused by MSI.

Patients And Methods: We performed a retrospective cohort study of inpatients with MSI in the maxillofacial region from January 2012 to October 2016.

Diagnosis and Treatment of Gorham-Stout Disease in Maxillofacial Regions.

Purpose: This study was aimed to investigate the clinical features, imaging examination, and treatment of the patients with Gorham-Stout disease (GSD) in maxillofacial region, so as to improve the understanding of GSD.

Methods: The medical records of the patients with GSD who were referred to Shanghai Ninth People's Hospital from January 2010 to May 2016 were reviewed. Their ages, lesion location, imaging results, laboratory examination results, treatment, and therapeutic effects were analyzed.

Risk Factors Affecting the Prognosis of Descending Necrotizing Mediastinitis From Odontogenic Infection.

Purpose: Descending necrotizing mediastinitis (DNM) is a serious complication of head and neck infections and has an excessively high mortality rate owing to the lack of understanding of DNM. We assessed the clinical characteristics, diagnosis, treatment, and outcomes of odontogenic DNM and evaluated the risk factors affecting the prognosis of DNM to provide an up-to-date overview for clinical practice.

Materials And Methods: We performed a retrospective cohort study, enrolling a sample of patients with DNM due to odontogenic infection who had been referred from January 2013 to December 2016.
