Abstract
Whereas the cellular and molecular features of human inflammatory skin diseases are well characterized, their tissue context and systemic impact remain poorly understood. We thus profiled human psoriasis (PsO) as a prototypic immune-mediated condition with a high predilection for extracutaneous involvement. Spatial transcriptomics (ST) analyses of 25 healthy, active lesion, and clinically uninvolved skin biopsies and integration with public single-cell transcriptomics data revealed marked differences in immune microniches between healthy and inflamed skin. Tissue-scale cartography further identified core disease features across all active lesions, including the emergence of an inflamed suprabasal epidermal state and the presence of B lymphocytes in lesional skin. Both lesional and distal nonlesional samples were stratified by skin disease severity and not by the presence of systemic disease. This segregation was driven by macrophage-, fibroblast-, and lymphatic-enriched spatial regions with gene signatures associated with metabolic dysfunction. Together, these findings suggest that mild and severe forms of PsO have distinct molecular features and that severe PsO may profoundly alter the cellular and metabolic composition of distal unaffected skin sites. In addition, our study provides a valuable resource for the research community to study spatial gene organization of healthy and inflamed human skin.

Abstract
Acanthosis Nigricans is considered to be a skin marker of insulin resistance and atherosclerosis. It is rarely reported in cases of insulinoma where there is marked hyperinsulinaemia. We report two cases of insulinoma with acanthosis nigricans which regressed, concomitant with significant weight loss and reduction in blood pressure following surgical resection. This strengthens the hypothesis that hyperinsulinaemia is responsible for Acanthosis nigricans and atherosclerotic risk factors.

Abstract
Inconsistent data exist regarding the diagnostic value of acanthosis nigricans (AN) or skin tags as clinical markers for obesity or diabetes. In an outpatient department-based prospective study, we designed a scoring for AN severity (SCANS) to evaluate AN and skin tags, their correlation with obesity or diabetes. Quantification of AN in six anatomic sites, in consideration of the affected skin surface areas, texture changes, number of skin tags, leads to a total severity score between 0 and 46. Among 336 adult patients (aged ≥18 years) with AN, a higher BMI was associated with AN (r = 0.299, P < .001), but not with diabetes (P = .43), as compared with 243 age- and sex-matched controls without AN. Among nondiabetics, AN scores were significantly correlated with waist circumference (r = 0.131, P = .024) and total cholesterol levels (r = 0.155, P = .04). Skin tags alone in the absence of AN were not associated with obesity (P = .333) or diabetes (P = .164). The total AN scores were positively correlated with the presence of skin tags (r = 0.132, P < .001), and the involvement of anterior neck (r = 0.668, P < .001) and axilla (r = 0.793, P < .001). Knuckles and groins were unaffected in our series. Our results indicate that combination of AN with skin tags can be used as clinical marker for obesity, but not for diabetes. Large-scale studies on patients of different ethnic background are required to further validate our proposed scoring.

Abstract
Background Insulin resistance (IR) is a pre-diabetic condition and has been reported in patients with acanthosis nigricans (AN) and acrochordon. AN and acrochordon are claimed to be cutaneous markers of IR. Aim The purpose of this paper was to study the association of AN and acrochordon with IR. Methods It was a cross-sectional hospital-based study. Both groups were assessed for IR by using homeostatic model assessment of insulin resistance (HOMA-IR) formula. Results A total of 70 cases and an equal number of controls were studied. IR was observed more in cases (41.4%) compared to controls (17.1%) (P < 0.01). Mean HOMA-IR value was also significantly higher in cases (4.32 ± 4.44) compared to controls (2.27 ± 0.90) (P < 0.05). Limitations Low number of cases and controls were taken in the study. Association with hyperlipidemia and metabolic syndrome was not elicited. Conclusions AN and acrochordons were found to be associated with IR.

Abstract
Any clinical/biochemical marker revealing obesity or diabetes before their appearance is valuable. Insulin resistance (IR) is present in both disorders many years before occurrence. Accordingly, we determined whether acanthosis nigricans (AN) in the knuckles is associated to higher insulin and homeostasis model assessment for estimated insulin resistance (HOMA-IR) index values, and assessed the influence of body-mass index (BMI) and the diagnostic performance of AN in the knuckles to detect IR. In this cross-sectional controlled study, we included men or women, 18 to 23 years old, with or without AN in the knuckles. In 149 cases with AN in the knuckles and 145 controls, fasting insulin was higher in cases (13.45 µU/mL ± 7.8 vs. 8.59 µU/mL ± 3.63, P < .001, respectively). Mean HOMA-IR index was also higher (2.86 ± 1.68 vs. 1.78 ± 0.77, P < .001). A significant increase in fasting insulin and HOMA-IR values between and within BMI groups from normal through obese category was identified in controls and cases. By multivariate regression analysis, cases with normal BMI were significantly associated to a HOMA-IR ≥2.5 (OR = 3.09, CI95% = 1.75-5.48, P = .001). A model of AN in the knuckles, normal BMI, and increased waist circumference allowed identifying 2 out of 3 cases with HOMA-IR index ≥2.5. AN in the knuckles could be addressed with two aims: as an easy, accessible, and costless diagnostic tool suggesting hyperinsulinemia secondary to IR, and, an early marker of IR even in the absence of overweight or obesity.

Abstract
OBJECTIVE Obesity is known to be a risk factor for many diseases including dermatological problems. Here, we aimed to determine the cutaneous manifestations in obese patients and the frequency of the accompanying dermatoses and to investigate the effect of diabetes mellitus in obese patients on cutaneous manifestations compared with the control group. METHODS Our study included a total of 600 adults: 450 obese volunteers and 150 healthy volunteers. The number of diabetic obese patients was 138 (30%), whereas that of nondiabetic obese patients was 312 (70%). A detailed dermatological examination was performed for each case, and accompanying dermatoses were compared. RESULTS The mean body mass index (BMI) in the obese patients and control group was 37.22 kg/m2 and 22.23 kg/m2, respectively. The most common dermatoses in the obese patients were, according to their frequency: striae distensae (291 patients, 64.7%), acrochordon (236 patients, 52.4%), acanthosis nigricans (213 patients, 47.3%), plantar hyperkeratosis (209 patients, 46.4%), and venous insufficiency (202 patients, 44.9%). Although hirsutism was more frequently observed in the nondiabetic obese group than in the diabetic obese group, stasis dermatitis was less frequently observed (p<0.05). CONCLUSION We found that many dermatoses are more frequently observed in the obese patients than in the controls. We observed that the effect of obesity on skin is different from that of diabetes mellitus and that cutaneous manifestations of obesity occur more frequently. More extensive, comprehensive, and advanced studies on this subject are required.

Abstract
Abstract Objective : The aim of this study was to perform a systematic review of the major skin diseases affecting obese individuals and their influence on physical activity. Methods : Relevant articles were identified by systematically searching PubMed from 2000 to 2014, using the descriptors "skin diseases" and "obesity", "skin disease" and "obesity", "skin diseases" and "physical activity", "skin disease" and "physical activity". The PEDro Scale (in Brazilian Portuguese) was used to rate the methodological quality of the studies. Results : A total of 320 articles were examined in the first phase. In the end, 11 articles met the proposed criteria and were included for analysis in the systematic review. We investigated cutaneous manifestations of diseases and classified them according to their effects under 5 categories: metabolic (n = 10), aesthetic (n = 7), inflammatory (n = 6), mechanical (n = 5) and infectious (n = 3). The most frequent dermatoses among obese were acanthosis nigricans, acrochordon (skin tags), stretch marks, plantar keratodermia, intertrigo, bacterial and fungal infections. Acanthosis nigricans was found to be the most important metabolic implication of obesity. Conclusion : Although neglected, skin lesions are common in obesity and have implications for physical activity because they cause pain, discomfort, friction, infection, inflammation, embarrassment, limitation or difficulty of movement. Strategies to promote skin health may result in a better integration of physical activity into routine therapy and improve the quality of life of obese individuals.

Abstract
OBJECTIVES The aim of this study is to identify factors accounting for the variation in 25-hydroxyvitamin D levels in a pediatric obese population. PATIENTS AND METHODS One hundred and forty-nine obese children and adolescents (BMI ≥95th percentile) were evaluated in a pediatric endocrine office. Acanthosis nigricans (AN) skin lesions were rated on a 4-point scale. RESULTS The 25-hydroxyvitamin D levels were significantly different between those without AN and those with any severity of AN (p=<0.001). Insulin levels were only significantly different between those with no and severe AN (p=0.007). A general linear model showed that month of visit predicted 19.0% of the variation and AN an additional 2.2%. When AN was dropped from the full model, log-transformed HOMA-IR remained insignificant (p=0.164). CONCLUSIONS Season of evaluation was the main determinant of 25-hydroxyvitamin D levels. Severity of AN was a stronger predictor of 25-hydroxyvitamin D level variation than the measure of insulin resistance HOMA-IR.

Abstract
INTRODUCTION The prevalence of obesity has increased worldwide in recent years. Some authors have described skin conditions associated with obesity, but there is little evidence on the association between insulin levels and such disorders. OBJECTIVE To describe the skin disorders present in overweight and obese patients and analyze their association with insulin levels. MATERIAL AND METHODS The study included nondiabetic male and female patients over 6 years of age who were seen at our hospital between January and April 2011. All the patients were evaluated by a dermatologist, who performed a physical examination, including anthropometry, and reviewed their medical history and medication record; fasting blood glucose and insulin were also measured. The patients were grouped according to degree of overweight or obesity and the data were compared using analysis of variance or the χ(2) test depending on the type of variable. The independence of the associations was assessed using regression analysis. RESULTS In total, 109 patients (95 adults and 13 children, 83.5% female) were studied. The mean (SD) age was 38 (14) years and the mean body mass index was 39.6±8 kg/m(2). The skin conditions observed were acanthosis nigricans (AN) (in 97% of patients), skin tags (77%), keratosis pilaris (42%), and plantar hyperkeratosis (38%). Statistically significant associations were found between degree of obesity and AN (P=.003), skin tags (P=.001), and plantar hyperkeratosis. Number of skin tags, AN neck severity score, and AN distribution were significantly and independently associated with insulin levels. CONCLUSIONS AN and skin tags should be considered clinical markers of hyperinsulinemia in nondiabetic, obese patients.

Abstract
Acanthosis nigricans (AN) usually correlates to insulin resistance (IR) or obesity in obese populations, but adequate studies on the significance of AN in people with normal body mass index (BMI) have not been performed and discussed. Three hundred and thirty-nine polycystic ovary syndrome (PCOS) patients with normal BMI (<23 kg/m(2) ) were recruited. The anthropometric and biochemical parameters of these patients were measured. In these patients with normal BMI, 33 (9.7%) women had AN, and six (1.77%) women were diagnosed with metabolic syndrome. Most of the anthropometric and biochemical variables associated with metabolic status were more unfavorable in the AN-positive group compared with the AN-negative groups. The prevalence of central obesity, IR and reduced high-density lipoprotein cholesterol (HDL-C) level were also significantly higher in the AN-positive group (P < 0.05). In multiple regression analysis, presence of AN was still significantly associated with IR (odds ratio [OR] = 2.952, 95% confidence intervals [CI] = 1.367-6.376] and reduced HDL-C level (OR = 2.668, 95% CI = 1.160-6.135) after adjustments for age and BMI. Sensitivity, specificity, and positive and negative predictive values for AN to detect IR were 18.6%, 92.6%, 39.4% and 81.4%, respectively. In conclusion, presence of AN correlated with IR and reduced HDL-C level in PCOS women with normal BMI. AN status had high specificity to detect IR, but lack of sensitivity.

Abstract
INTRODUCTION Acanthosis nigricans is a non-specific reaction pattern that may accompany obesity, diabetes, excess corticosteroids, pineal tumors, malignancies, and other endocrine disorders. It is considered a cutaneous marker of tissue insulin resistance. AIMS AND OBJECTIVES To determine the prevalence of acanthosis nigricans in type 2 diabetes mellitus (DM) and its correlation with various anthropometric measurements and insulin resistance by HOMA-IR and other metabolic parameters. MATERIALS AND METHODS One hundred and fifty consecutive subjects with newly diagnosed type 2 DM, attending the endocrinology OPD of LLRM Medical College, Meerut were studied. Acanthosis was graded based on standard scale of 0-4 as described by Burke et al. Anthropometric data were obtained and insulin resistance calculated as HOMA-IR from fasting insulin and fasting blood sugar values. RESULTS The average age of the study population was 45.2 years, with male to female ratio of 1:5. The prevalence of acanthosis in males was 56.67% and in females was 86.92%. The acanthosis neck severity grading had a statistically significant correlation with fasting glucose levels, fasting insulin levels, and insulin resistance values: HOMA-IR, HOMA-S, and HOMA-B (P < 0.05). Other acanthosis parameters such as axillary grading, acanthosis at knuckles, and skin tags, did not have a statistically significant correlation with insulin resistance. CONCLUSION Acanthosis nigricans neck severity grading correlates well with insulin resistance and can be used as a clinical surrogate for assessment of severity of insulin resistance.

Abstract
Insulin resistance is a metabolic disorder in which target cells fail to respond to normal levels of circulating insulin. Insulin resistance has been associated with presence of acanthosis nigricans and acrochordons. It is known that early diagnosis and early initial treatment are of paramount importance to prevent a series of future complications. These dermatoses may represent an easily identifiable sign of insulin resistance and non-insulin-dependent diabetes.
