Abstract

The combination of modern bivalved operative laryngoscopes, laryngeal telescopes and videotaping techniques has given us a new tool in the objective evaluation of organic laryngeal lesions. The purpose of the present study has been to describe a new method for direct video-laryngoscopy, an alternative to the classical Kleinsasser microlaryngoscopy technique, in diagnosis, clinical documentation and endolaryngeal microsurgery under video control without using an operating microscope. The direct video-laryngoscopy system consists of: a Weerda distending operating laryngoscope, Hopkins rod lens and Lumina telescopes (0 degrees, 25 degrees, 70 degrees or Mueller subglottoscope), an original telescope holder for a distending laryngoscope, a lightweight medical videocamera, a VHS videorecorder, laryngoscope holder and chest support. From November 1987 to May 1989, 370 patients with laryngeal lesions were examined and recorded. Only in 3 cases was the microlaryngoscopy technique used as it proved difficult to introduce the telescope into its holder because of patient anatomy: one short-necked, obese patient, and two with a prominent tongue base and limited ability to open the mouth. In 367 cases direct video-laryngoscopy made careful ...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.
