Monitoring of naevus density--an approximate marker of previous UV exposure--in children at school enrollment as a method to detect shifts in melanoma risk in the population

Abstract

Naevus density in children depends both on constitutional factors (see below) and on previous (solar) UV exposure, which is a well-known risk factor for malignant melanoma. Secular trends of childhood UV exposure - e. g., due to intervention programmes - can be monitored by repeated, standardised cross-sectional studies assessing naevus density in children. The 'CMONDE-Study (childhood monitoring of naevus density)' appears as a suitable instrument, introduced into the process of school enrollment for children of the years 1999 and 2000 in Göttingen. Analyses are based on 3883 children. Median age was 6.25 years, the proportion of girls 47 %. Median naevus density was 5.8/m(2), with an increase of density from 'Fitzpatrick skin type' IV to II, but marked decrease in type I. Similarly, naevus density increased with increasing lightness of hair colour, but was very low in red-haired individuals. While the number of freckles was also strongly associated with naevus density, the association between iris colour and skin darkness, respectively, was weak. To meet the objective of continual monitoring, further comparative cross-sectional studies are needed.

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.
