Abstract

The 1450 nm laser shrinks sebaceous glands histologically, reduces seborrhoea and has been shown in numerous small uncontrolled studies to improve inflammatory acne. To assess objectively the clinical efficacy and long-term outcome of the 1450 nm laser for inflammatory acne vulgaris. Participants over 16 years of age with moderate to severe acne vulgaris were recruited from a secondary care dermatology department. A split-face format was used: the side of the face to be treated was randomized with the other side serving as a within-patient control. Treatment was delivered with the Candela 1450 nm Smoothbeam laser (Candela, Cwmbran, U.K.) using a double-pass technique, 6 mm spot size, 210 ms pulse duration and fluence of 8 or 9 J cm(-2) . Three treatments were performed monthly. The primary outcome was the change in inflammatory lesion count and grading (using the Leeds Revised Acne Grading Scale) between baseline and 4 weeks after the third treatment on the treated side as compared with the change in the control side. Participants were followed up every 3 months for 12 months after the last treatment. The single assessor was blinded as to the side treated. Thirty-eight participants entered the study and 32 completed the study a...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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Congenital Hyperinsulinism

Congenital hyperinsulinism is caused by genetic mutations resulting in excess insulin secretion from beta cells of the pancreas. Here is the latest research.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

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.
