Abstract

Merkel cell carcinoma (MCC) is a rare tumor of the skin. A retrospective analysis of 12 cases of MCC diagnosed and treated over a 14-year period. Seven females and 5 males, with a median age of 72 years and MCC of the face (5), trunk (1) and extremities (6), were studied. The stage was I in 2 cases and II in 10. Eight patients had surgery, two surgery and chemotherapy and two chemotherapy only. The last two patients died of disease after 10 and 16 months. Three patients suffered locoregional recurrence after 4, 6 and 24 months and three were lost to follow-up after 8, 9 and 24 months while disease-free. Two disease-free patients died of unrelated causes after 4 and 48 months, while three were alive and well after 24, 48 and 84 months. The three relapsing patients received chemotherapy in addition to local radiation in one case. One is alive and well, the other alive with disease and the third died of disease after 84, 107 and 10 months, respectively. MCC often recurs locally. Surgery is the treatment of choice, while radiotherapy is important for local control. Chemotherapy produces responses in the neoadjuvant setting or after relapse.

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.
