Teledermatology to reduce face-to-face appointments in general practice during the COVID-19 pandemic: a quality improvement project.

BMJ Open Qual 2022 May;11(2)

School of Medicine, University of St Andrews, St Andrews, UK.

Teledermatology is an important subspecialty of telemedicine that continues to evolve with advances in telecommunication and mobile phone technology. A 19-week primary care quality improvement project collected baseline data and tested three change ideas, using the Model for Improvement method, with primary and secondary aims: to increase the weekly percentage of remote dermatological consultations with supporting images that were successfully concluded remotely to greater than 80% and to reduce the weekly percentage of dermatological face-to-face consultations to less than 50%. We hypothesised that by improving the quality of patient images and the confidence of reception staff in triaging skin complaints, there would be a decrease in the weekly number of face-to-face dermatological appointments, thereby decreasing the risk of COVID-19 transmission within the practice and community.

Epidermal growth factor receptor inhibitors (EGFRIs) have been established as first-line standard-of-care therapies for non-small cell lung cancer (NSCLC) but are frequently accompanied by adverse dermatological effects, in particular, acneiform rash. There is no effective clinical intervention, partially because of its poorly understood etiology. Here, we show that inhibition of EGFR initiated keratinocyte HaCaT cell cycle arrest and apoptosis, which fueled a robust secondary inflammatory response. Read More

Facial Plast Surg 2022 May 26. Epub 2022 May 26.

Otorhinolaryngology, Acibadem University, Istanbul, Turkey.

The attenuation of retaining ligaments with aging leads to downward displacement of facial fat compartments, and is responsible for many of the stigmata that occur with aging. The zygomatic cutaneous and masseteric cutaneous ligaments prevent the transmission of adequate traction to the malar portion of the dissection during traditional low SMAS facelift techniques which involve plication or imbrication of the exposed surface of the SMAS because they do not include surgical release of these ligaments. Inadequate release of these ligaments, especially the zygomatic cutaneous ligament may lead to an unbalanced, unnatural appearance with unopposed nasolabial folds. Read More

Organ-specific response after low-dose interleukin-2 therapy for steroid refractory chronic Graft-versus-Host Disease.

Blood Adv 2022 May 26. Epub 2022 May 26.

Dana-Farber Cancer Institute; Harvard Medical School, Boston, Massachusetts, United States.

Despite new therapeutic options, treatment of steroid-refractory chronic graft-versus-host disease (SR-cGVHD) remains challenging as organ involvement and clinical manifestations are highly variable. In previous trials of low-dose interleukin-2 (LD IL-2), we established the safety and efficacy of LD IL-2 for treatment of SR-cGVHD. In the present report, we combined 5 phase I or II clinical trials conducted at our center to investigate organ-specific response rate, co-involvement of organs, predictors of organ-specific response and its possible association with immune response.

Down-Regulating Scar Formation by Microneedles Directly a Mechanical Communication Pathway.

ACS Nano 2022 May 26. Epub 2022 May 26.

Institute of Burn Research, State Key Laboratory of Trauma, Burn and Combined Injury, Southwest Hospital, Third Military Medical University (Army Medical University), Chongqing 400038, China.

Excessive extracellular matrix deposition drives fibroblasts into a state of high mechanical stress, exacerbating pathological fibrosis and hypertrophic scar formation, leading to tissue dysfunction. This study reports a minimally invasive and convenient approach to obtaining scarless tissue using a silk fibroin microneedle patch (SF MNs). We found that by tuning the MN size and density only, the biocompatible MNs significantly decreased the scar elevation index in the rabbit ear hypertrophic scar model and increased ultimate tensile strength close to regular skin.

Microbiota and maintenance of skin barrier function.

Science 2022 May 26;376(6596):940-945. Epub 2022 May 26.

Departments of Dermatology and Microbiology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, USA.

Human skin forms a protective barrier against the external environment and is our first line of defense against toxic, solar, and pathogenic insults. Our skin also defines our outward appearance, protects our internal tissues and organs, acts as a sensory interface, and prevents dehydration. Crucial to the skin's barrier function is the colonizing microbiota, which provides protection against pathogens, tunes immune responses, and fortifies the epithelium. Read More

Department of Biomedical Engineering, Northwestern University, Evanston, IL 60208, USA.

Temporary postoperative cardiac pacing requires devices with percutaneous leads and external wired power and control systems. This hardware introduces risks for infection, limitations on patient mobility, and requirements for surgical extraction procedures. Bioresorbable pacemakers mitigate some of these disadvantages, but they demand pairing with external, wired systems and secondary mechanisms for control. Read More

Overcoming pH defenses on the skin to establish infections.

PLoS Pathog 2022 May 26;18(5):e1010512. Epub 2022 May 26.

Department of Immunology and Microbiology, University of Colorado School of Medicine, Aurora, Colorado, United States of America.

Skin health is influenced by the composition and integrity of the skin barrier. The healthy skin surface is an acidic, hypertonic, proteinaceous, and lipid-rich environment that microorganisms must adapt to for survival, and disruption of this environment can result in dysbiosis and increase risk for infectious diseases. This work provides a brief overview of skin barrier function and skin surface composition from the perspective of how the most common skin pathogen, Staphylococcus aureus, combats acid stress.

RRM1 variants cause a mitochondrial DNA maintenance disorder via impaired de novo nucleotide synthesis.

J Clin Invest 2022 May 26. Epub 2022 May 26.

Department of Neurology, Columbia University Irving Medical Center, New York, United States of America.

Mitochondrial DNA (mtDNA) depletion/deletions syndromes (MDDS) encompass a clinically and etiologically heterogenous group of mitochondrial disorders due to impaired mtDNA maintenance. Among the most frequent causes of MDDS are defects in nucleoside/nucleotide metabolism, which is critical for synthesis and homeostasis of the deoxynucleoside triphosphate (dNTP) substrates of mtDNA replication. A central enzyme for generating dNTPs is ribonucleotide reductase, a critical mediator of de novo nucleotide synthesis composed of catalytic RRM1 subunits in complex with RRM2 or p53R2. Read More
