Abstract

Port wine stains (PWSs) are commonly treated with pulsed dye laser (PDL) as a standard therapy. However, it is not easy to predict the minimal effective dose in the first treatment session. The aim of this study was to assess whether dermoscopic findings before and after laser irradiation corresponded with the clinical improvement of PWS in patients undergoing PDL therapy. Seven untreated PWSs in 6 patients (a male and 5 females), who presented to our hospital between May 2008 to January 2010, were assessed in this study. The mean age was 36.3 years, ranging from 14 to 57 years. A PDL with a wavelength of 585 nm and a spot size of 7 mm was used. Before and after test irradiation, patients underwent dermoscopy and clinical photography, and we assessed whether the dermoscopic findings corresponded with clinical improvement after 3 months. There were no obvious differences observed in the clinical photographs between each test level immediately after irradiation. However, dermoscopic photographs showed differences as the irradiated energy increased. These changes corresponded to the clinical improvement after 3 months. Our study indicates that the minimal effective fluence can be predicted by observing dermoscopic change immediate...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.
