Abstract

Dyspnea caused by bilateral vocal cord paralysis often requires surgical intervention to prevent acute asphyxiation. The regeneration of the laryngeal nerves may last weeks or months and it is difficult to predict the outcome. In the past decades, several open and endoscopic surgical techniques have been introduced for treatment to avoid tracheostomy, however, these procedures with resection of the glottis resulted in irreversible changes in the laryngeal structure, thus the voice quality decreased over a long-term period. Endoscopic arytenoid abduction lateropexy is an accepted reversible, minimally invasive technique that provides an immediate patent airway by the lateralisation of the arytenoid cartilage with a suture. The aim of our study was to analyze the phonatory and respiratory outcomes of this treatment concept. Two patients suffering from bilateral vocal cord palsy were treated with endoscopic arytenoid abduction lateropexy. After recovery of the vocal cord movements, the sutures were removed. Spirometric and phoniatric results of the two patients were analysed after suture removal. Good spirometric parameters and normal voice quality were detected in both cases. These results prove the high reversibility of the mini...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
