Alopecia Risk and the Thickness, Number, and Frequency of Scalp Skin Harvests

Abstract

The aim of this study was to elucidate the relationships between the thickness, number, and frequency of scalp skin harvests and alopecia risk.In a PubMed search, the search terms (scalp AND graft AND alopecia) were used, resulting in 148 papers. Among 21 abstracts, 11 full papers were reviewed, and 3 papers were ultimately analyzed.The donor-site alopecia rate was significantly higher in patients who experienced hair growth on their grafts than in those who did not (odds ratio = 10.875, 95% confidence interval, 2.677-44.178; P < 0.001). The depth of the infundibulum can be estimated to be 451.8 μm at 5 years of age, 528.8 μm at 10 years, 605.8 μm at 15 years, and 682.8 μm at 20 years. Therefore, the limits of safe thickness for graft harvesting from the scalp are <18/1000 inches for 5-year olds, 21/1000 inches for 10-year olds, 24/1000 inches for 15-year olds, and 27/1000 inches for 20-year olds. The safe number of harvests (intersection of the alopecia and nonalopecia groups) was 2.7, and the safer number of harvests (limits of 2 standard deviations of the alopecia group) was 1.0. The safe time interval between harvests was 14.0 days, and the safer time interval between harvests was 15.6 days. The safe single minimal interval...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.
