Superficial radiotherapy (SRT) treatment for non-melanoma skin cancer has been reported to yield variable cure rates. When patients are highly selected, adequate margins of treatment are chosen, and hypofractionation is avoided, cure rates of SRT can approach that of Mohs surgery.

The objective of this study is to evaluate long term results of our center’s SRT selection criteria and define proper decision-making parameters of optimal candidates for treatment, and to review the literature. A retrospective chart analysis was done of all SRT cases from 2012-2018. Location, size, type and depth of the treated tumors were defined. Treatment energy, fractionation, and radiation field size were documented. Recurrences and complications were analyzed. Of 131 treated lesions treated, head and neck lesions (105, 80%) were the most common location, primarily on the lower nose (60, 46%). Of 122 lesions analyzed for recurrence, 2 (1.6%) recurred, with a mean follow-up time of 5 years. Acute ulcerations in 29 (28%) head and neck lesions, 5 (63%) trunk lesions, and 9 (50%) leg lesions occurred. Delayed ulcerations occurred in 5 (28%) leg lesions. In conclusion, when patients are highly selected, long-term SRT cure rates up to 98% can be achieved.

Obesity represents a serious health problem as it is rapidly increasing worldwide. Obesity is associated with reduced health span and life span, decreased responses to infections and vaccination and increased frequency of inflammatory conditions. In this review, we summarize published data showing that obesity increases the risk of different types of infections, with a special focus on skin infections. Obesity also induces skin changes and conditions (inflammation-based and hypertrophic) which are often associated with fungi or bacteria overgrowth. The association of obesity with the skin microbiome has been established in both mice and humans. Balance of commensal microbes controls skin homeostasis and the host immune response, while changes in normal physiologic skin microbiome composition and pathologic bacteria contribute to skin diseases. We also summarize the major steps in wound healing and how obesity affects each of them. The role that immune cells have in this process is also described. Although the studies summarized in this review clearly demonstrate the deleterious effects of obesity on wound healing, additional studies are needed to better characterize the cellular and molecular mechanisms involved and identify specific targets of intervention.

Photodynamic therapy (aPDT) has become an important component in the treatment of human infection. This report highlights the scientific literature and clinical guidelines on aPDT in the context of dermatology and considers the treatment of skin infection in all settings now, and in the future. Antibiotic resistance, infection control strategies and technologies able to eradicate microbes without building up new resistance are considered, and their mechanisms of action are described. Published work and National Institute for Clinical Excellence (NICE) Technology appraisals (TA) and research recommendations within Clinical Guidelines were used to identify future applications for PDT. Nanotheranostics can include PDT and were found to be highly relevant, and so treatment combinations and their novel applications will be subject to TA and Randomised Clinical Trials (RCTs). The resistance of some microbes to antibiotics can be reversed through use of supplementary drugs, and so they are likely to remain a mainstay of treatment for skin infection.

Dermatological manifestations of connective tissue diseases (CTDs) are common and frequently precede other symptoms. Thus, dermatologists may be the first clinicians to diagnose these disorders. Silica exposure is an acknowledged cause of several CTDs, but this is under-appreciated by clinicians, who may also be unaware of the wide range of jobs in which silica exposure can occur. The CTDs associated with silica exposure include systemic sclerosis (SSc), rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), anti-neutrophil cytoplasmic antibody (ANCA) positive vasculitis and overlap syndromes. Silica-related systemic sclerosis (Si-SSc) is associated with a specific antibody profile and more severe disease. Silicosis has re-emerged worldwide recently due to several new workplace exposures, including a new type of silicosis (artificial stone (AS) silicosis), which is associated with a particularly high rate of auto-antibody formation. Dangerous work practices are still occurring. This article summarises recent literature on the topic of the resurgence of silicosis and silica-induced CTDs and reminds dermatologists of the importance of taking a thorough occupational history in all patients. Early intervention in CTDs and reduction in dust exposure can reduce risk and improve prognosis. Treatment options are rapidly improving.

Nodular melanoma is the second most common subtype of melanoma. Unlike other subtypes, nodular melanoma is characterized by early vertical growth rather than the typical initial radial growth of most melanomas. As a result, nodular melanoma presents clinically in a more aggressive phenotype. Given its more aggressive nature and intrinsic ability to mimic benign lesions, a modified acronym has been developed to allow clinicians to better evaluate, diagnose and treat nodular melanoma in earlier stages. Surgical excision with wide margins is the gold standard of nodular melanoma therapy; however, an emphasis in early detection, diagnosis, staging, and treatment needs to be emphasized among clinicians due to its dismal prognosis in later stages, as compared to other subtypes. A better understanding of the molecular pathophysiology that allows nodular melanoma to act aggressively very early in diagnosis is necessary for the development of therapeutics that may effectively target lesions in more advanced stages.

Cancer is one of the leading causes of death worldwide. In the U.S. alone, almost 2 million people will be diagnosed with cancer each year and just over a quarter of those diagnosed will pass away from the disease. Skin cancers are the most common forms of cancer. Early detection of cancer and cancer biomarkers enables clearer understanding of cancer progression in a patient and more effective treatments in response to the disease. Clinically relevant biomarkers are not only tools for early diagnosis of cancer but may also prove useful as immune targets for various immunotherapies, such as monoclonal antibody-based therapy and chimeric antigen receptor (CAR) T-cell therapy. This review provides a brief overview of the rescue pathway enzyme thymidine kinase 1 (TK1) and its history and biology, as well as discusses its role as a biomarker and potential immune target.

Immune checkpoint inhibitors (ICIs) have revolutionized cancer therapy, and their use in combination with radiation therapy (RT) has become increasingly utilized to optimize positive outcomes. The cutaneous adverse reactions from RT as well as ICIs are both well documented; however, in combination these cutaneous toxicities can be exacerbated. ICIs and RT may work synergistically to create an enhanced immune response against the tumor cells. This synergistic effect has been reported to occur both locally at the site of RT, as well as systemically via an abscopal effect. Fortunately, this combination of treatment does not increase the incidence of cutaneous reactions, although several cases have reported enhanced skin toxicity at the site of RT. RT is thought to create an ‘immunocompromised skin district’ or localized immune dysregulation in irradiated skin. This review summarizes previously published case reports and discusses the cutaneous adverse reactions from ICI and RT combination therapy. Properly identifying ICI and RT induced skin reactions depends on several factors including patient history, sequence of therapies, timing of reaction, and histological findings. Skin reactions from combination therapy can range in severity and include ICI-induced radiation recall dermatitis, as well as uncommon presentations of Stevens-Johnson syndrome, lichen planus, and bullous pemphigoid which are localized to or enhanced within areas of prior radiation exposure. It is important for oncologists and dermatologists alike to be aware of the spectrum of reactions associated with ICI and RT.

Intense pulsed light (IPL) are medical-esthetical procedures that emit light at a wavelength of 500 – 1200 nm, interacting with epidermal and dermal tissues. IPL is a relatively new treatment of growing popularity thanks to its versatility and efficacy, mainly in dermatology and recently also in ophthalmology. These devices are used to treat dry eye disease, meibomian gland dysfunction, rosacea, and periocular lesions with outstanding results.

There is a well-known shortage of racial diversity in medical textbooks and literature contributing to race-based health care inequalities1. We present the case of a black puertorrican 58-year-old female who developed a painful non-pruritic blistering ulcer in the inner oral mucosa with associated erythema six months prior to the evaluation. She was misdiagnosed on multiple occasions leading to a rapid progression of the disease, and subsequently, her death. Lack of images in medical textbooks and scarce literature describing initial presentation per-skin-tone of Pemphigus Vulgaris (PV) in patients with dark skin color led to misdiagnosis, delay in treatment, and thus, this catastrophic outcome. This case report describes the appearance of PV in patients with dark skin tone and serves as an educational resource by providing images of a rare skin disease in people with dark skin. The purpose of this case report is to fill major gaps in medical literature, highlight the importance of timely recognizing PV in patients with dark skin, and to create awareness among physicians.

Facial aging associated with volume loss can be addressed with soft tissue fillers. This minimally invasive technique has quickly gained popularity and is commonly performed in many outpatient settings. The composition of injectable dermal fillers includes marketed hyaluronic acid, calcium hydroxyapatite, polylactic acid, silicone and polymethylmethacrylate. Complications, such as vision loss, are rare, but can result in a devastating and irreversible sequala from iatrogenic vascular occlusion. Understanding the facial anatomy, specific filler characteristics, and having a safe injection technique is crucial to assure optimal aesthetics results while avoiding complications. Injectors need to be able to recognize early complications and treat them appropriately, especially if vision loss is encountered. This review will focus on vision loss from fillers, techniques to prevent such complications and possible treatment strategies.

Although there is a general appreciation of the mechanical abilities of cells in creating the forms in nature, we understand relatively little about how the mechanobiology of cells can affect behavior. Recent studies of the effects of mechanical activity indicate that exercise and other physical perturbations can inhibit cancer progression and performance loss in aging. Thus, the tumor cell and senescent cell states are mechanically different from normal cells. New tools to measure cellular forces and the downstream biochemical changes that result from mechanical signaling have enabled the description of the matrix rigidity sensor that is missing in the vast majority of tumor cells. Tumor cells no longer form tumors upon its restoration; whereas normal cells have unregulated growth when the sensor is depleted. Further, mechanical strain of tumor cells will cause apoptosis and may have effects on keratinocyte and melanocyte tumors. This could explain some of the anti-tumor benefits of physical activity. In the case of aging, the negative effects of senescent cells on their neighbors appear to be reversed by small but not large mechanical strains in skin. Thus, cells in the tumor or senescent states respond specifically to mechanical perturbations and a deeper understanding of the important aspects of mechanobiology can be used in therapies to augment biochemical therapies to benefit the patient.

Considering all topical applications, products target very different body areas including mucosa, healthy or impaired skin with many specific characteristics in the epithelium composition, structure and barrier functionality. In vitro reconstructed human tissue models are recognized as being sensitive and reliable in preclinical studies. On top of validated methods for skin irritation, new and predictive experimental protocols can be designed to address specific applications. The objective of this study was therefore to investigate the behavior of ingredients with a well-known tolerance profile for specific applications using 3D human reconstructed models: gingival and vaginal focusing on mucosa tolerance, “immature” epidermis intended to be closer to baby skin, and a fourth epidermis model with a physically impaired barrier function. Ingredients with a key function were applied at usual doses and compared to controls and formulation benchmarks to challenge the predictivity of the models.

The analysis of the results of each in vitro model demonstrated their greater sensitivity compared to the standard reconstructed human epidermis, making it possible to evaluate the tolerance of ingredients and select a well-tolerated dosage according to the local application area. The multiparametric approach designed for the “immature” and “impaired” epithelia models enriched basic irritation information with cellular, morphological and functional effects evaluations. It was therefore possible to identify some infra-clinical reactions and study the ingredient mechanisms.
