Abstract

The follow-up of the patients submitted to surgery for laryngeal carcinoma requires both clinical and CT examinations, particularly in the cases at high risk of recurrence. Our series consisted of 72 laryngeal carcinoma patients operated on and regularly followed-up with CT to distinguish relapse from normal or abnormal postoperative changes. Seventy-two laryngeal carcinoma patients were submitted to surgery: total laryngectomy was performed in 33 cases, supraglottic laryngectomy in 16 cases, Labayle subtotal laryngectomy in 18 cases and Mayer Piquet subtotal laryngectomy in 5 cases. The patients were followed-up postoperatively with CT and 94 examinations were performed in all; pathology was performed in all the cases with radiologic suspicion of recurrence (19 patients) and further clinical examinations were performed to exclude recurrence in the 14 cases where imaging findings were questionable. Local recurrences were confirmed in 16 of 19 patients with positive CT findings. Radiologically, the recurrence appeared as an irregular thickening of the pharyngo-laryngeal wall with inhomogeneous density after i.v. contrast agent infusion. The patients submitted to total or supraglottic laryngectomy recurred most often at the crani...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.
