Neonatal cytosteatonecrosis: Hypercalcemia with nephrocalcinosis

Cytosteonecrosis (CSN) is a rare pathology that is poorly described in the medical literature. Its pathogenesis is still poorly elucidated, and it generally develops in the neonatal period. Diagnosed clinically, it presents as indurated, purplish skin patches on fair skin or hyperchromic patches on black skin

Actinic keratosis and field cancerization: Profile of patients of a dermatology service in the city of Lagarto/SE

Objective: to evaluate the epidemiological profile, pattern of sun exposure, protective measures and lesion characteristics of patients with actinic keratosis and field cancerization in the city of Lagarto/SE. Methodology: this is a descriptive, cross-sectional and quantitative study using questionnaires over a period of 12 months. Results: the sample included 127 participants, the majority was female, with light skin phototype, low education, average age of 60 years and occupations more exposed to the sun. Participants tended to expose themselves to the sun during the period with the highest incidence of ultraviolet rays, the majority used mechanical photoprotection measures, but only about half of them used sunscreen. Of the total, 124 participants reported having skin lesions, most for more than 1 year, with associated symptoms and in areas of the body most exposed to the sun. Conclusion: most participants belong to risk groups for actinic keratosis and/or skin cancer, work in occupations exposed to the sun, in addition to being exposed at the most critical times of the day. The use of mechanical photoprotection barriers was superior to the use of sunscreen. The characteristics of the interviewees' skin lesions may indicate a delay in reaching the specialized service, making it important to adjust the local flow to optimize care for this population and ensure their early referral.

Sensitivity Response Analysis of Optical Surface Monitoring Systems Using the Fitzpatrick Scale: A Phantom Study

PurposeOptical Surface Monitoring systems (OSMS) have gained substantial attention in modern radiotherapy, specifically in the context of Surface Guided Radiation Therapy (SGRT) which offers real-time patient surface monitoring, ensuring accurate and effective radiotherapy treatments. The aim of this paper is to evaluate the OSMS camera sensitivity towards different skin tones, categorized according to the Fitzpatrick scale, a universal classification of human skin tones, using a phantom. Methods and MaterialThe study utilized Catalyst and SentinelTM OSMS systems (C-Rad, Uppsala, Sweden). The Alderson RANDO Female Pelvis phantom, located at the isocenter in CT simulation and treatment rooms, served as an experimental subject. Eighteen skin tone matching cotton cloths, selected based on Von Luschan's chromatic and Fitzpatrick scales, were wrapped around the phantom for sensitivity evaluation. Camera sensitivity was optimized by adjusting threshold/gain (100-600%) and integration time during individual scans in both rooms. Temporal response analysis spanned two months, with sixteen measurements for each OSMS taken in varying light conditions. ResultsThe OSMS systems successfully detected the surface of cloth-covered phantoms with varying mean (standard deviation) integration times: 550 (34) to 950 (43) μs for the Sentinel system and 2300 (71) to12000 (400) μs for the Catalyst system. The sensitivity parameters differed for each skin tone, with lighter skin requiring shorter integration times and gain/threshold values. Darker skin tones necessitated higher parameters for optimal surface images. The reliability of the systems declined with excessive parameters, leading to noise and compromised accuracy in patient positioning. ConclusionsOptimized sensitivity parameters tailored to individual skin tones are crucial for effective real-time patient surface monitoring in radiation therapy, as variations in skin colour can affect the accuracy of measurements. The precision of skin colour measurements in OSMS relies on carefully adjusting camera sensitivity parameters. However, careful consideration is essential, as larger values are required for darker skin tones, compromising reliability. This suggests the need for exploring alternative image guidance methods for patients with darker skin tones.

Visual Learning Equity Initiative Enhances Preclinical Dermatologic Image Representation: A Cross-Sectional Study.

Despite growing diversity in the United States population, studies show that medical education lacks representation of conditions in darker skin tones. Given that medical conditions present differently in different skin tones, limited exposure to images of darker tones in medical training may contribute to incorrect or delayed diagnoses, perpetuating health inequities. This study examines the preclinical curriculum at the Georgetown University School of Medicine (GUSOM) to report on its image representation with respect to skin tone and to assess the impact of a student-driven initiative in achieving visual learning equity (VLE). Of 1050 preclinical images, 58.2% depicted conditions in light/white skin tones, 31.3% in medium/brown, and 10.5% in dark/black. The microbiology and pathology courses had the highest percentages of dark/black and medium/brown images. Infectious disease images made up 36.3% of all images with 54.6% light/white, 31.5% medium/brown, and 13.9% dark/black. Overall, the first images representing conditions were 63.5% light/white, 30.0% medium/brown, and 6.6% dark/black. When dark/black images were presented first, 64.3% were of infectious diseases, compared to 35.1% for medium/brown and only 28.4% for white/light first images that were infectious diseases. A significant increase in images of conditions in darker skin tones was observed in the IRD course 2022 compared to the IRD course 2020 (P<.001). Our study highlights an underrepresentation of darker skin tones compared to lighter skin tones in the GUSOM preclinical curriculum. A student-led initiative significantly increased the representation of darker skin tones in dermatologic images, demonstrating the potential impact of such efforts in achieving VLE in medical education.J Drugs Dermatol. 2024;23(7):519-524.  doi:10.36849/JDD.7992.

Topical corticosteroids in the treatment of acute sunburn: a systematic review

Background: Acute sunburn is a prevalent dermatological issue, particularly affecting individuals with fair skin types I-III. It is characterized by erythema, edema, and discomfort due to ultraviolet (UV) radiation exposure. Topical corticosteroids are commonly used for their anti-inflammatory properties, but their efficacy in sunburn treatment is debated due to limited high-quality evidence from randomized controlled trials (RCTs). This study aims to assess the efficacy of topical corticosteroids in relieving symptoms and inflammation of sunburn. Methods: A systematic review was conducted by searching PubMed, Web of Science, ProQuest, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) for studies published up to April 30, 2024. Keywords included combinations of terms related to corticosteroids, topical application, and sunburn. Studies were selected based on PRISMA 2020 guidelines, focusing on adult patients treated with topical corticosteroids compared to placebo. Data extraction and quality assessment were independently performed by two researchers using the Cochrane Collaboration’s Risk of Bias tool. Results: The review included six RCTs with a total of 339 participants, aged 18-68 years, conducted in Europe and the USA. Various topical corticosteroids were studied, including methylprednisolone aceponate, hydrocortisone 17-butyrate, and hydrocortisone-21-acetate. Treatment durations ranged from single applications to twice daily for seven days. The results demonstrated that prolonged treatment with topical corticosteroids significantly reduced sunburn symptoms such as erythema and pain. When applied for seven days, treated areas showed lower sunburn reaction scores and reduced inflammation compared to untreated areas. Early application of corticosteroids, particularly within 6 hours post-exposure, was more effective than later applications. Histological analyses supported these findings, showing improvements in epidermal thickness and reduced dermal inflammation in treated areas. Conclusion: Topical corticosteroids can effectively alleviate acute sunburn symptoms and aid skin recovery by targeting inflammatory pathways. Their efficacy is enhanced with prolonged and early application. Further research is needed to optimize treatment protocols and assess long-term effects to fully realize the therapeutic potential of corticosteroid therapy in managing acute sunburn.

Investigation on the influence of the skin tone on hyperspectral imaging for free flap surgery

Hyperspectral imaging (HSI) is a new emerging modality useful for the noncontact assessment of free flap perfusion. This measurement technique relies on the optical properties within the tissue. Since the optical properties of hemoglobin (Hb) and melanin overlap, the results of the perfusion assessment and other tissue-specific parameters are likely to be distorted by the melanin, especially at higher melanin concentrations. Many spectroscopic devices have been shown to struggle with a melanin related bias, which results in a clinical need to improve non-invasive perfusion assessment, especially for a more pigmented population. This study investigated the influence of skin tones on tissue indices measurements using HSI. In addition, other factors that might affect HSI, such as age, body mass index (BMI), sex or smoking habits, were also considered. Therefore, a prospective feasibility study was conducted, including 101 volunteers from whom tissue indices measurements were performed on 16 different body sites. Skin tone classification was performed using the Fitzpatrick skin type classification questionnaire, and the individual typology angle (ITA) acquired from the RGB images was calculated simultaneously with the measurements. Tissue indices provided by the used HSI-device were correlated to the possible influencing factors. The results show that a dark skin tone and, therefore, higher levels of pigmentation influence the HSI-derived tissue indices. In addition, possible physiological factors influencing the HSI-measurements were found. In conclusion, the HSI-based tissue indices can be used for perfusion assessment for people with lighter skin tone levels but show limitations in people with darker skin tones. Furthermore, it could be used for a more individual perfusion assessment if different physiological influencing factors are respected.

A practical classification scale for the dermatology management of individuals with skin of color: the colorimetric scale for skin of color.

A simple and rapid method that is not based on race and ethnicity for classifying people with skin of color is of paramount importance in dermatology. The currently used Fitzpatrick classification of sun-reactive skin types is inadequate. Newer scales that have been used in immigration surveys and sociology studies are not applicable in the office setting. A new, non-racial and non-ethnic, colorimetric scale for skin of color has recently been proposed that is simple to perform. The scale has five colors: very light beige (skin color type 1), light brown (skin color type 2), medium brown (skin color type 3), dark brown (skin color type 4) and very dark brown (skin color type 5); an individual with white skin, such as in albinism, would have a skin color type 0 in this classification. In conclusion, the colorimetric scale enables the rapid classification of individuals with skin of color and allows for accurate assessment of skin cancer risk, more appropriate management of cosmetic dermatologic procedures and aesthetic devices, and enhanced ability for focused counseling regarding hair products, skin care interventions, and color-targeted makeup based on the person's skin tone.

Targeted metabolomics revealed the seasonal plasticity of skin color and pigment metabolites in ornamental koi carp

The koi carp is an ornamental fish that was obtained through artificial selection from the common carp (Cyprinus carpio L.). The most economically important traits of koi are their beautiful skin patterns in bright colors. As seasonality is an important factor in the biology and ecology of fish, we thus assumed that seasonal changes are involved in regulating the formation of skin color and patterns of koi carp. The white, red, cyan, and black skin colors from four varieties of scaleless koi carp (Doitsu Shiromuji (W), Doitsu Kohaku (WR), Doitsu Showa Sanke (WRI), and Kumonryu (WI)) were evaluated using the CIELab color space (lightness, redness, and yellowness) in different seasons. Compared to winter, the yellowness of the white color in all koi varieties decreased in summer and autumn. The black skin color areas in WRI and WI koi increased in summer and autumn compared to winter. The yellowness of the red color decreased only in WRI koi, while no changes were observed in WR koi. Targeted metabolomics analysis revealed that the levels of the structural pigment guanine of all koi varieties showed significant seasonal variation. Of seven detected carotenoids, the zeaxanthin and tunaxanthin contents in W, WI, and WRI koi changed with the seasons, while none of the carotenoids in WR koi were altered. Of the seven potential regulatory metabolites, epinephrine, melatonin, and cyclic adenosine monophosphate (cAMP) in all four koi varieties showed the highest levels in winter. A correlation analysis suggested that the seasonal changes in white skin color occurred through the epinephrine-cAMP pathway; melanin-dependent and carotenoid-dependent skin color changes occurred through melatonin in koi carp. This study demonstrated the seasonal plasticity of skin color in koi carp regulated by melatonin and epinephrine, associating with variety and color specificity.

Fairness & Privacy in an Age of Generative AI

Generative AI technologies have made tremendous strides recently and have captured the public’s imagination with their ability to mimic what was previously thought to be a fundamentally human capability: creativity. While such technologies hold great promise to augment human creativity and automate tedious processes, they also carry risks that stem from their development process. In particular, the reliance of foundation models on vast amounts of typically uncurated, often web-scraped training data has led to concerns around fairness and privacy. Algorithmic fairness in this context encompasses concerns around potential biases that can be learned by models due to skews in their training data and then reflected in their generated outputs. For example, without intervention, image generation models are more likely to generate images of lighter skin tone male individuals for professional occupations and images of darker skin tone female individuals for working class occupations. This further raises questions around whether there should be legal protections from such pernicious stereotypical representations. Privacy is also a concern as generative AI models can ingest large amounts of personal and biometric information in the training process, including face and body biometrics for image generation and voice biometrics for speech generation. This Essay will discuss the types of fairness and privacy concerns that generative AI raises and the existing landscape of legal protections under anti-discrimination law and privacy law to address these concerns. This Essay argues that the proliferation of generative AI raises challenging and novel questions around (i) what protections should be offered around the training data used to develop such systems and (ii) whether representational harms should be protected against in an age of AI-generated content.

Topical and Intralesional Immunotherapy for the Management of Basal Cell Carcinoma.

Basal Cell Carcinoma (BCC) is the most common type of cancer among the white population. Individuals with fair skin have an average lifetime risk of around 30% for developing BCC, and there is a noticeable upward trend in its incidence rate. The principal treatment objectives for BCC involve achieving the total excision of the tumor while maximizing the preservation of function and cosmesis. Surgery is considered the treatment of choice for BCC for two main reasons: it allows for the highest cure rates and facilitates histological control of resection margins. However, in the subgroup of patients with low-risk recurrence or medical contraindications for surgery, new non-surgical treatment alternatives can provide an excellent oncological and cosmetic outcome. An evident and justified instance of these local therapies occurred during the COVID-19 pandemic, a period when surgical interventions carried out in hospital settings were not a viable option.

Morphological structure and ethnic background of the Sudanese Shagia tribe (East Africa)

North Sudan, especially the 4th Nile Cataract region, is home to one of the world’s most isolated human populations. This study aimed to clarify the ethnic background of the Shagia based on anthropological analyses. This study provides a morphological and ethnographic characterisation of the previously unstudied Shagia tribe. Head and body measurements were conducted among 64 adults from three villages. There were observable but relatively small admixture proportions of non-African population genes (light skin colour, narrow noses and masculine proportions) in their morphological build. The Shagia’s uniqueness may have been the result of severe genetic drift episodes resulting from founding events, such as long-term isolation and traditionally small population size. It is useful to trace the ethnic history of Africans and, specifically, for the tribal members of Shagia so that they may better understand and learn about their history. This study shows that the Shagia tribe was displaced from their territory due to the construction of the Merowe Dam. Thus, the results of this research fulfil the assumptions of urgent anthropology, as it contributes to the protection of the heritage of the 4th Nile Cataract region: an area of historical value to the study of the evolution of contemporary civilisation.

Monte Carlo simulation of the effect of melanin concentration on light-tissue interactions for transmittance pulse oximetry measurement.

Questions about the accuracy of pulse oximeters in measuring arterial oxygen saturation ( ) in individuals with darker skin pigmentation have resurfaced since the COVID-19 pandemic. This requires investigation to improve patient safety, clinical decision making, and research. We aim to use computational modeling to identify the potential causes of inaccuracy in measurement in individuals with dark skin and suggest practical solutions to minimize bias. An in silico model of the human finger was developed to explore how changing melanin concentration and arterial oxygen saturation ( ) affect pulse oximeter calibration algorithms using the Monte Carlo (MC) technique. The model generates calibration curves for Fitzpatrick skin types I, IV, and VI and an range between 70% and 100% in transmittance mode. was derived by inputting the computed ratio of ratios for light and dark skin into a widely used calibration algorithm equation to calculate bias ( ). These were validated against an experimental study to suggest the validity of the Monte Carlo model. Further work included applying different multiplication factors to adjust the moderate and dark skin calibration curves relative to light skin. Moderate and dark skin calibration curve equations were different from light skin, suggesting that a single algorithm may not be suitable for all skin types due to the varying behavior of light in different epidermal melanin concentrations, especially at 660nm. The ratio between the mean bias in White and Black subjects in the cohort study was 6.6 and 5.47 for light and dark skin, respectively, from the Monte Carlo model. A linear multiplication factor of 1.23 and exponential factor of 1.8 were applied to moderate and dark skin calibration curves, resulting in similar alignment. This study underpins the careful re-assessment of pulse oximeter designs to minimize bias in measurements across diverse populations.

Is diet related to skin condition? A Mendelian randomization study.

Observational studies have revealed associations between various dietary factors and skin conditions. However, the causal relationship between diet and skin condition is still unknown. Data on 17 dietary factors were obtained from the UK Biobank. Data on four skin conditions were derived from the UK Biobank and another large-scale GWAS study. Genetic predictions suggested that the intake of oily fish was associated with a lower risk of skin aging (OR: 0.962, P = 0.036) and skin pigmentation (OR: 0.973, P = 0.033); Tea intake was associated with a lower risk of skin pigmentation (OR: 0.972, P = 0.024); Salad/raw vegetables intake was associated with a lower risk of keratinocyte skin cancer (OR: 0.952, P = 0.007). Coffee intake was associated with increased risk of skin aging (OR: 1.040, P = 0.028); Pork intake was associated with increased risk of skin aging (OR: 1.134, P = 0.020); Beef intake was associated with increased risk of cutaneous melanoma (OR: 1.013, P = 0.016); Champagne plus white wine intake was associated with increased risk of cutaneous melanoma (OR: 1.033, P = 0.004); Bread intake was associated with increased risk of keratinocyte skin cancer (OR: 1.026, P = 0.013). Our study results indicate causal relationships between genetically predicted intake of oily fish, tea, salad/raw vegetables, coffee, pork, beef, champagne plus white wine, and bread and skin conditions.

Exploring the bias: how skin color influences oxygen saturation readings via Monte Carlo simulations.

Our goal is to understand the root cause of reported oxygen saturation ( ) overestimation in heavily pigmented skin types to devise solutions toward enabling equity in pulse oximeter designs. We aim to gain theoretical insights into the effect of skin tone on curves using a three-dimensional, four-layer tissue model representing a finger. A finger tissue model, comprising the epidermis, dermis, two arteries, and a bone, was developed using a Monte Carlo-based approach in the MCmatlab software. Two skin tones-light and dark-were simulated by adjusting the absorption and scattering properties within the epidermal layer. Following this, curves were generated in various tissue configurations, including transmission and reflection modes using red and infrared wavelengths. In addition, the influence of source-detector (SD) separation distances on both light and dark skin tissue models was studied. In transmission mode, curves did not deviate with changes in skin tones because both pulsatile and non-pulsatile terms experienced equal attenuation at red and infrared wavelengths. However, in reflection mode, measurable variations in curves were evident. This was due to differential attenuation of the red components, which resulted in a lower perfusion index at the red wavelength in darker skin. As the SD separation increased, the effect of skin tone on curves in reflection mode became less pronounced, with the largest SD separation exhibiting effects similar to those observed in transmission mode. Monte Carlo simulations have demonstrated that different light pathlengths within the tissue contribute to the overestimation of in people with darker skin in reflection mode pulse oximetry. Increasing the SD separation may mitigate the effect of skin tone on readings. These trends were not observed in transmission mode; however, further planned research using more complex models of the tissue is essential.

Characteristics of and foundation application among Chinese females with sensitive skin.

We conducted a study on women with sensitive skin of various skin tones to analyse their skin characteristics and preferences for foundation shades. Volunteers were categorized based on their individual typological angle, and their preferences were assessed using self-perception and software-based mass aesthetic assessment. The Baumann Questionnaire is a valuable tool for identifying patients with sensitive skin and gaining a comprehensive understanding of their skin sensitivity. The skin characteristics of two groups were compared using a more suitable classification method. Individuals diagnosed with sensitive skin typically have skin tones classified as Types I, II and III, with Type I being the most common in sensitive skin cases. The sensitive group exhibited higher levels of transepidermal water loss, lighter skin tone, lower yellowness, increased glossiness, higher haemoglobin content, more acne, fewer blackheads, and fewer pores. Among them, Type I skin is characterized by lower elasticity, increased oiliness, higher hydration levels and fewer visible pores. Type II skin is characterized by lower hydration levels, higher oiliness and increased redness. Type III exhibits more pores, decreased oiliness and enhanced elasticity. Foundations No. 2 and No. 3 are fairer than foundations No. 1 and No. 4. In the self-assessment, Type I and Type II subjects preferred No. 3, while Type III subjects preferred No. 1 and No. 4 because they matched their skin tone. The results of the software evaluation showed that popular aesthetics preferred Type I and Type II to use No. 2, and Type III to use No. 2 and No. 3, as they resulted in a fairer complexion. Sensitive skin of different skin tone types confronts different skin problems. The findings also highlight the public's inclination towards lighter foundation shades, despite the common practice of selecting shades that harmonize with one's inherent skin tone.

IS BEING FAIR … REALLY LOVELY?

Dear Reader, Fairness of skin is most sought after by the Asians and Africans and the whole world clamours for products which are for either (a) skin whitening; (b) skin lightening; or (c) skin bleaching. The global ‘fairness’ products market is valued at USD 10 billion (` ~80,000 crore). The market in India is estimated to be worth nearly ` 5,000-10,000 crore and the average growth rate in the last two decades has been a healthy (sic) 20%. It is not only the Indians who are fanatic about looking ‘fairer’, the people of Nigeria and Ghana rule in this regard. This is evident from the list of top 5 countries whose population are frequent users of various skin products globally.

Analysis of the amino acid profile of red and white graphs winery by-products from western Sicily

Nowadays, research addressing the composition of nutrients and bioactive compounds in waste from the agri-food industry has increased due to environmental and economic interests. The wine industry produces enormous quantities of by-products every year along the production chain. The nitrogen content in wine grapes is important for the yeast's metabolism and growth, playing a key role in both grape and wine quality. Besides research in grapes and derived products, few studies are present in the literature on the characterization of the amino acid content of wine industry by-products. In this context, this preliminary research aims at the application of a methodological approach for the identification and quantification of amino acids profile from grape by-products (red and white skins, red and white defatted grape seeds) by HPLC-FLD analysis. The most abundant amino acid in red skins was leucine (3.163 g/100 g), while in white skins was histidine (1.886 g/100 g). Higher amounts of leucine, histidine and phenylalanine were found in red seeds, compared to white seeds. By-products of the wine industry, due to the presence of essential amino acids, together with other bioactive substances contained, can be used as functional ingredients for food fortification.

The relationship between racial/ethnic identification and body ideal internalization, hair satisfaction, and skin tone satisfaction in black and black/white biracial women

Eurocentric physical characteristics, including a thin, tall physique, long straight hair, and fair skin, typify Western beauty standards. Past research indicates that for Black women, greater identification with one’s racial/ethnic culture may buffer against internalizing Eurocentric beauty standards, specifically the thin ideal. Black/White Biracial women often experience different appearance pressures from each of their racial identity’s sociocultural appearance ideals. Unfortunately, body image research is limited among Bi/Multiracial individuals. Participants were recruited online via Prime Panels, a high-quality data recruitment service provided by CloudResearch. Participants, M(SD)Age= 34.64 (12.85), self-reported their racial/ethnic identification, thin and thick/curvy ideal internalization, and hair and skin tone satisfaction. Using linear regression analyses, we assessed whether racial/ethnic identification buffered against monoracial Black (n = 317) and Black/White Biracial (n = 254) women’s thin ideal internalization. Additionally, we assessed whether stronger racial/ethnic identity was associated with stronger thick/curvy ideal internalization and hair and skin tone satisfaction. Supporting hypotheses, greater racial/ethnic identification was associated with higher thick/curvy ideal internalization and hair and skin tone satisfaction among both Black and Biracial women. Contrary to hypotheses, greater racial/ethnic identification was not associated with lower thin ideal internalization in either group. Our results stress the need to use racially and culturally sensitive measurements of body image.

Worldwide internet trends in the public interest related to skin whitening and bleaching creams

ABSTRACT Skin whitening is a practice that is used to obtain lighter skin tone and is most prevalent in Africa and Asia. Substances used for this procedure, such as hydroquinone or mercury have a variety of side effects and are banned in several countries. This study examined the popularity of internet searches for terms related to skin whitening and bleaching creams with the use of GoogleTrends (GT). GT was searched globally for the topic “skin whitening” and two terms “hydroquinone cream” and “mercury cream” throughout a 10-year period (01.09.2013–31.08.2023). The popularity of searches increased during the analyzed period. The topic “skin whitening” was most popular in Sudan, Vietnam, and Sri Lanka. The searches were higher for “hydroquinone cream” than “mercury cream” in almost all countries, besides the Philippines and Indonesia. Our study confirms that skin whitening practices are popular, especially among populations with darker skin tone. Despite potentially toxic side effects, creams with hydroquinone and mercury are increasingly searched worldwide. Education about skin whitening and the usage of bleaching substances should be implemented, especially in the regions of Africa and Asia.
