Abstract
Skin color classification can have importance in skin health, pigmentary disorders, and oncologic condition assessments. It is also critical for evaluating disease course and response to a variety of therapeutic interventions and aids in accurate classification of participants in clinical research studies. A panel of dermatologists conducted a literature review to assess the strengths and limitations of existing classification scales, as well as to compare their preferences and utilities. We identified 17 skin classification systems utilized in dermatologic settings. These systems include a range of parameters such as UV light reactivity, race, ethnicity, and degree of pigmentation. The Fitzpatrick skin type classification is most widely used and validated. However it has numerous limitations including its conflation with race, ethnicity, and skin color. There is a lack of validation data available for the remaining scales. There are significant deficiencies in current skin classification instruments. Consensus-based initiatives to drive the development of validated and reliable tools are critically needed.

Abstract
INTRODUCTION Software to predict the impact of aging on physical appearance is increasingly popular. But it does not consider the complex interplay of factors that contribute to skin aging. OBJECTIVES To predict the +15-year progression of clinical signs of skin aging by developing Causal Bayesian Belief Networks (CBBNs) using expert knowledge from dermatologists. MATERIAL AND METHODS Structures and conditional probability distributions were elicited worldwide from dermatologists with experience of at least 15 years in aesthetics. CBBN models were built for all phototypes and for ages ranging from 18 to 65 years, focusing on wrinkles, pigmentary heterogeneity and facial ptosis. Models were also evaluated by a group of independent dermatologists ensuring the quality of prediction of the cumulative effects of extrinsic and intrinsic skin aging factors, especially the distribution of scores for clinical signs 15 years after the initial assessment. RESULTS For easiness, only models on African skins are presented in this paper. The forehead wrinkle evolution model has been detailed. Specific atlas and extrinsic factors of facial aging were used for this skin type. But the prediction method has been validated for all phototypes, and for all clinical signs of facial aging. CONCLUSION This method proposes a skin aging model that predicts the aging process for each clinical sign, considering endogenous and exogenous factors. It simulates aging curves according to lifestyle. It can be used as a preventive tool and could be coupled with a generative AI algorithm to visualize aging and, potentially, other skin conditions, using appropriate images.

Abstract
Hyperpigmentation disorders greatly impact the quality of life of many patients. Vitamin C and ascorbic acid derivatives are commonly used as topical agents to reduce the effect of facial dyschromia. The market for vitamin C topicals has greatly increased, but with little oversight, resulting in a wide variety of products with regard to purity and efficacy. In this study, we conducted an analysis of the most highly rated vitamin C-containing compounds on Amazon and Sephora. It was found that consumers for both retailers prioritized efficacy and cosmetic elegance in their rating of products. Additionally, consumers displayed no preference among vitamin C derivatives in the products available to them. This study highlights the diverse vitamin C formulations currently available as well as consumer preferences, emphasizing the importance of fully reviewing all products patients are utilizing to better counsel on treatment regimens.

Abstract
BACKGROUND In cosmetic dermatology, lasers and lights treat a variety of hair and skin conditions, including some that disproportionately affect people of color. AIMS Our systematic review aims to understand the representation of participants with skin phototypes 4-6 in cosmetic dermatologic trials studying laser and light devices. METHODS A systematic literature search was conducted using search terms "laser," "light," and multiple laser and light subtypes in the PubMed and Web of Science databases. All randomized controlled trials (RCTs) published between January 1, 2010 and October 14, 2021 that studied laser or light devices for cosmetic dermatologic conditions were eligible for inclusion. RESULTS Our systematic review included 461 RCTs representing 14 763 participants. Of 345 studies that reported skin phototype, 81.7% (n = 282) included participants of skin phototypes 4-6, but only 27.5% (n = 95) included participants of skin phototypes 5 or 6. This trend of excluding darker skin phototypes persisted when results were stratified by condition, laser of study, study location, journal type, and funding source. CONCLUSIONS Trials studying lasers and lights for the treatment of cosmetic dermatologic conditions need better representation of skin phototypes 5 and 6.

Abstract
BACKGROUND Exogenous ochronosis (EO) is a deposition disease associated with application of hydroquinone-containing preparations. Characteristic ochronotic bodies (OBs) arise from endogenous connective tissues, most often reported as collagen. We highlight a significant role for elastic fibers as a precursor tissue. OBJECTIVE To evaluate elastic tissue pathology in EO, specifically as it relates a precursor role in ochronotic body formation. METHODS In this retrospective observational study, a literature review using PubMed/MEDLINE database was conducted to ascertain the most commonly ascribed precursor connective tissue. Eleven histopathologic cases of EO were identified. Patient demographics and clinical characteristics were recorded. Slides were reviewed for the presence and grade of solar elastosis (SE), the relationship of OBs to elastotic material, the presence of elastotic fibers transitioning to OBs, and positivity of bodies with Verhoeff-van Gieson elastic tissue stain. RESULTS Elastic fibers are uncommonly reported as the major precursor tissue of OBs. SE was uniformly present in our cases, and the majority demonstrated heavy/high-grade elastosis. Elastotic fibers transitioning to OBs were observed in all cases, and the bodies demonstrated Verhoeff-van Gieson positivity. LIMITATIONS Small sample size. CONCLUSIONS Ochronotic body formation is associated with SE, and bodies appear to arise from damaged elastic fibers.

Abstract
INTRODUCTION Meta-analyses of genetic association studies are affected by biases and quality shortcomings of the individual studies. We previously developed and validated a risk of bias tool for use in systematic reviews of genetic association studies. The present study describes a larger empirical evaluation of the Q-Genie tool. METHODS AND ANALYSIS MEDLINE, Embase, Global Health and the Human Genome Epidemiology Network will be searched for published meta-analyses of genetic association studies. Twelve reviewers in pairs will apply the Q-Genie tool to all studies in included meta-analyses. The Q-Genie will then be evaluated on its ability to (i) increase precision after exclusion of low quality studies, (ii) decrease heterogeneity after exclusion of low quality studies and (iii) good agreement with experts on quality rating by Q-Genie. A qualitative assessment of the tool will also be conducted using structured questionnaires. DISCUSSION This systematic review will quantitatively and qualitatively assess the Q-Genie's ability to identify poor quality genetic association studies. This information will inform the selection of studies for inclusion in meta-analyses, conduct sensitivity analyses and perform metaregression. Results of this study will strengthen our confidence in estimates of the effect of a gene on an outcome from meta-analyses, ultimately bringing us closer to deliver on the promise of personalised medicine. ETHICS AND DISSEMINATION An updated Q-Genie tool will be made available from the Population Genomics Program website and the results will be submitted for a peer-reviewed publication.

Abstract
Multiple endocrine neoplasia type 1 (MEN1) is a familial tumor syndrome with autosomal dominant inheritance. Cutaneous tumors in MEN1, which include multiple angiofibromas, collagenomas, and lipomas can easily be overlooked because of their subtle appearance. As markers of this tumor syndrome, recognition of the mucocutaneous manifestations of MEN1 is important in order to facilitate early interdisciplinary care and diagnosis of associated internal disease in both patients and family members.

Abstract
Graham-Little-Piccardi-Lassueur syndrome (GLPLS) traditionally describes patients with a triad of a multifocal cicatricial alopecia of the scalp, noncicatricial alopecia of the axillae and groin, and a lichenoid follicular eruption. The entity has caused much controversy with respect to both etiology and clinical definition. We present a patient with lichen planopilaris, lichen planus pigmentosus, and nonscarring alopecia of the genitals, who is reminiscent of GLPLS. Recent work shows evidence for autoimmunity in GLPLS. Further elucidation of underlying mechanisms can improve categorization and treatment options in this rare and controversial syndrome.

Abstract
Plate-like osteoma cutis is a rare disorder that has been historically classified as a congenital syndrome. It has a possible relationship to a mutation in the gene (GNAS1) that encodes the α-subunit of the stimulatory G protein, which regulates adenyl cyclase activity. We report a case of extensive plaque-like masses on the scalp and face with no abnormalities in calcium or phosphate metabolism and no preceding inflammatory cutaneous conditions. With less than ten reported cases, to our knowledge, this is one the few cases of acquired plate-like osteoma cutis described in the literature.

Giant, multi-loculated hidrocystomas represent a rare variant of the common, benign hidrocystoma. Hidrocystomas are generally 1-3 mm and rarely exceed 10 mm. We describe a case of giant multi-loculated hidrocystomas 1-2 cm in size that were located near both upper and lower eyelids. Multiple modalities have been used to treat hidrocystomas, including excision, pulsed-dye laser, electrodesiccation, curettage, tricholoracetic acid, botulinum toxin, and anticholinergics.

Abstract
We have recently discovered that de-N-acetyl GM3 [NeuNH(2)LacCer, d-GM3], a derivative of ganglioside GM3, is specifically expressed in metastatic tumor cells and that its expression correlates with an enhanced metastatic phenotype. Although the classic N-acetylated form of GM3 (NeuAcLacCer, c-GM3) is found in both normal and tumor cells, metastatic tumor cells (but not other cells) predominantly express d-GM3 (82-95% of total GM3). d-GM3 expression is mainly found in metastatic melanomas, but not in benign nevi or the majority of primary melanomas. Using metastatic (d-GM3-positive) and poorly invasive (d-GM3-negative) human melanoma cell lines, we found that d-GM3 stimulates cell migration and invasion by increasing the expression and activation of urokinase-like plasminogen activator (uPA). Further studies showed that d-GM3 activates matrix metalloproteinase-2 (MMP-2), but not MMP-9, when uPA receptor signaling is activated. These results implicate d-GM3 as a specific marker for metastatic melanoma and a novel therapeutic target for neoplastic diseases.
