Background: The use of quantitative measures to assess patients' skin has turned the subjective nature of dermatology into an objective one. These measures allow for more accurate diagnosis and improved monitoring of diseases. While there are many skin analysis devices available, they often require specific equipment to function and can be costly, limiting their clinical use.
Aims: The aim of our study was to compare a new skin analysis device that is easy to incorporate into dermatologic practice to a standard validated device.
Methods: We recruited 50 patients from dermatology clinics and analyzed their skin with two facial analysis systems: an online application that can be downloaded on either an iPad or iPhone, and a computer-based analysis system that utilizes a facial imaging photobooth. Scores were recorded and compared between the two devices for the following five skin characteristics; "spots," "wrinkles," "redness," "texture," and "pores."
Results: The tablet and the computer analysis system had an agreement rate of 67.7%. The highest agreement was in assessing texture (72.0%) and pores (68.2%). The lowest agreeance was in assessing redness (64%) and wrinkles (67%). When assessing the relationship between patients' raw score for wrinkles and their age, there was a strong correlation with the tablet (r = 0.79, p < 0.0001) compared with the computer system (r = 0.26, p < 0.06).
Conclusions: The application utilized in our study may serve as a cost-effective and clinic friendly tool to assess patients' skin. It produces similar results to other skin analysis devices and may be more sensitive in detecting and quantifying wrinkles.

Background: Transcutaneous electrical stimulation after breast cancer surgery has been utilized for various purposes, but the full efficacy of this treatment approach on postoperative symptoms remains unclear.
Aim: This study aimed to answer the question: Does transcutaneous electrical nerve stimulation significantly impact postoperative patient outcomes in individuals undergoing breast cancer surgery?
Methods: A systematic review of randomized controlled trials was conducted. Because of the limited number of studies included, it was not feasible to perform a meta-analysis.
Group a remains viable inside fibrin clots and gains access to human plasminogen for subsequent fibrinolysis and dissemination.

Unlabelled: Group A (GAS) is a major human pathogen that causes several invasive diseases including necrotizing fasciitis. The host coagulation cascade initiates fibrin clots to sequester bacteria to prevent dissemination into deeper tissues. GAS, especially skin-tropic bacterial strains, utilize specific virulence factors, plasminogen binding M-protein (PAM) and streptokinase (SK), to manipulate hemostasis and activate plasminogen to cause fibrinolysis and fibrin clot escape.

The outbreak of the monkeypox epidemic underscores the importance of developing a rapid and sensitive virus detection technique. Microneedles (MNs) offer minimally invasive sampling capabilities, providing a solution for the development of integrated extraction and diagnostic portable devices. Here, we report an integrated MNs and hydrogel biosensor (IMHB) platform, composed of an electronic device, an MN patch, and a hydrogel patch.
