Clinical trial and detection of SARS-CoV-2 by a commercial breath analysis test based on Terahertz technology.

Public health threats such as the current COVID-19 pandemics have required prompt action by the local, national, and international authorities. Rapid and noninvasive diagnostic methods may provide on-site detection and immediate social isolation, used as tools to rapidly control virus spreading. Accordingly, the aim of the present study was to evaluate a commercial breath analysis test (TERA.

Endoscopic Inferior Meatal Antrostomy for Antrochoanal Polyps: A Long-Term Follow-Up.

Background: Endoscopic middle meatal antrostomy (EMMA) is considered the standard approach for surgical management of antrochoanal polyps (ACPs). Recently, an endoscopic inferior meatal antrostomy (EIMA) approach for clearing lesions in the maxillary sinus was described. In this study, we compared the long-term outcome of patients with ACP following surgical treatment using one of these 2 approaches (EIMA or EMMA).

Endoscopic treatment of ectopic teeth in the maxillary sinus.

Background: Ectopic teeth in maxillary sinus is rare and are usually removed via sub-labial trans-canine fossa approach (SLCFA). The aim of our study was to present our experience with extraction of ectopic teeth in the maxillary sinus via transnasal endoscopic approach (TEA).

Material And Methods: Rhinologists were asked to share their experience in the management of ectopic teeth in the maxillary sinus.

The Rationale for Endoscopic Inferior Meatal Antrostomy.

Background: Complete removal of some maxillary sinus pathologies may be challenging. We describe our experience in performing endoscopic inferior meatal antrostomy (EIMA) when approaching certain chronic maxillary sinus disease.

Methods: Retrospectively reviewing charts of all patients whose surgery included EIMA between the years 2012 and 2015.

Parathyroid surgery: correlation between pre-operative localization studies and surgical outcomes.

Objective: Pre-operative imaging techniques have enabled minimally invasive parathyroid surgery to supersede the traditional approach to hyperparathyroidism (HPT) surgery, which included cervical exploration. Cervical ultrasound (US) and sestamibi scan (MIBI) are commonly performed, but the results of these localization tests do not always match. This study correlated surgical outcomes with pre-operative localization findings, including matched positive US and MIBI studies, one positive study (US or MIBI), conflicting studies or negative results.

Exploring channeling optimized radiofrequency energy: a review of radiofrequency history and applications in esthetic fields.

Introduction: Because of its high efficiency and safety, radiofrequency (RF) energy is widely used in the dermatological field for heating biological tissue in various esthetic applications, including skin tightening, skin lifting, body contouring, and cellulite reduction. This paper reviews the literature on the use of nonablative RF energy in the esthetic field and its scientific background. The purpose of this article is to describe in detail the extensive use of medical devices based on RF technology, the development of these medical devices over the years, and recent developments and trends in RF technology.

Clioquinol effects on tissue chelatable zinc in mice.

Recent evidence for the involvement of zinc in the formation of beta-amyloid plaques in the brain in Alzheimer's disease has led to the establishment of new therapeutic strategies for the degenerative disorder based on metal chelation. The present experiment was conducted on a membrane-permeable zinc chelator, clioquinol (CQ), that has shown potential in initial studies on a mouse model of Alzheimer's disease [1]. The degree of chelatable zinc in mice treated with CQ, delivered by two different routes, was measured using complementary protocols for identifying chelatable zinc: 6-methoxy-8-quinolyl- p-toluenesulfonamide (TSQ) histofluorescence, and selenite autometalography.

Distribution of the zinc transporter ZnT-1 in comparison with chelatable zinc in the mouse brain.

Zinc maintains a diverse array of functions in the mammalian central nervous system as a key component of numerous enzymes, via its role in the activation of transcription factors, and as a neuroregulator, modulating neuronal receptors such as N-methyl-D-aspartate and gamma-aminobutyric acid. Zinc has a dark side, however, with massive influx of Zn(2+) to neurons considered to be a key factor in neuronal death secondary to ischemia and seizure. Several different putative zinc transporters, ZnT-1-4, have recently been identified and characterized.
