Evaluation of chronic pruritus and associated skin findings in patients with diabetes mellitus. Turk J Med Sci 2023; 53:1489-1497. [PMID: 38813039 PMCID: PMC10763738 DOI: 10.55730/1300-0144.5716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 10/26/2023] [Accepted: 09/09/2023] [Indexed: 05/31/2024] Open
Abstract
Background/aim To explore the dermatological lesions associated with chronic pruritus in patients who were followed up at our clinic for type 1 and type 2 diabetes mellitus (DM). Materials and methods The study population consisted of 249 patients with DM, who presented to the endocrinology clinic at Ankara University Faculty of Medicine between January 2022, and March 2022, regardless of whether they had reported experiencing pruritus symptoms. The visual analog scale and 5-D itch scale were used to determine the severity of itching in patients. Dermatological examination findings were also evaluated. Results Of the 249 patients with DM, mean duration since diabetes was diagnosed was 12 ± 9.2 [median 10 (0.3-46)] years, and the mean HbA1c levels were 8.1% ± 2.1%. Pruritus was detected in 77 (30.9%) patients and the mean duration of diabetes diagnosis was 13.4 ± 9.7 years. Examination of the microvascular and macrovascular complications showed that the incidence of retinopathy, nephropathy, neuropathy and peripheral arterial disease was 31.2% (p = 0.003), 31.2% (p = 0.005), 66.2% (p < 0.001) and 10.4% (p = 0.038), respectively, in the group with pruritus. These incidences were significantly higher in the group with pruritus than in those without pruritus. Dermatological examination showed that the most common condition was xerosis (64%), followed by fungal skin infection (16%) and bullous pemphigoid (8%). No skin findings were noted in 7% of patients who complained of itching. Conclusion Chronic pruritus may be associated with several factors such as poor glycemic control, high BMI and microvascular and macrovascular complications in patients with DM. Especially in patients with severe generalized pruritus who do not respond to standard antipruritic treatments, the use of DPP-4 inhibitors, a class of oral antidiabetic agents, should be questioned and all medications being used by the patient should be reviewed.

Abstract
Diabetes mellitus (DM) is one of the world's most important health problems, affecting more than half a billion of the world's population today, with an ever-increasing prevalence. Among the most common manifestations of diabetes are skin manifestations, with 30-70% of patients experiencing skin complications during the course of the disease. Conditions such as acanthosis nigricans, diabetic dermopathy, necrobiosis lipoidica, bacterial infections, fungal infections, skin xerosis, and metabolic prurigo are often associated with diabetes and often precede its diagnosis. We conducted a retrospective study on a group of 103 patients hospitalized between January 2018 and December 2022, in a clinic of a county hospital, using as criteria the diagnosis of diabetes mellitus complicated by cutaneous manifestations frequently associated with diabetes. The aim was to observe which are the most common manifestations and whether they correlate with data in the research literature. In the present study, manifestations such as diabetic foot (20% of patients), bacterial (35%) and fungal infections, and cutaneous xerosis (45%) were predominant. Often, the integumentary involvement may precede the diagnosis of the underlying disease. It is therefore very important to recognize, investigate and treat these manifestations as soon as possible.

Acta Biomater 2023; 158:324-346. [PMID: 36565785 DOI: 10.1016/j.actbio.2022.12.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 11/26/2022] [Accepted: 12/15/2022] [Indexed: 12/24/2022]
Abstract
In type 2 diabetes mellitus (T2DM), elevated glucose level impairs the biochemistry of the skin which may result in alteration of its mechanical and structural properties. The several aspects of structural and mechanical changes in skin due to T2DM remain poorly understood. To fill these research gaps, we developed a non-obese T2DM rat (Sprague Dawley (SD)) model for investigating the effect of T2DM on the in vivo strain stress state, mechanical and structural properties of skin. In vivo strain and mechanical anisotropy of healthy and T2DM skin were measured using the digital imaging correlation (DIC) technique and DIC coupled bulge experiment, respectively. Fluorescence microscopy and histology were used to assess the collagen and elastin fibers microstructure whereas nanoscale structure was captured through atomic force microscopy (AFM). Based on the microstructural observations, skin was modeled as a multilayer membrane where in and out of plane distribution of collagen fibers and planar distribution of elastin fibers were cast in constitutive model. Further, the state of in vivo stresses of healthy and T2DM were measured using model parameters and in vivo strain in the constitutive model. The results showed that T2DM causes significant loss in in vivo stresses (p < 0.01) and increase in anisotropy (p < 0.001) of skin. These changes were found in good correlation with T2DM associated alteration in skin microstructure. Statistical analysis emphasized that increase in blood glucose concentration (HbA1c) was the main cause of impaired biomechanical properties of skin. The presented data in this study can help to understand the skin pathology and to simulate the skin related clinical procedures. STATEMENT OF SIGNIFICANCE: Our study is significant as it presents findings related to the effect of T2DM on the physiologic stress strain, structural and mechanical response of SD rat skin. In this study, we developed a non-obese T2DM SD rat model which mimics the phenotype of Asian type 2 diabetics (non-obese). Several structural and mechanical characterization techniques were explored for multiscale characterization of healthy and T2DM skin. Further, based on microstructural information, we presented the constitutive models that incorporate the real microstructure of skin. The presented results can be helpful to simulate the realistic mechanical response of skin during various clinical trials.

Abstract
BACKGROUND Necrobiosis lipoidica (NL) is complicated by ulceration in up to 35% of cases. METHODS Retrospective study of patients with NL seen at our institution between January 1, 1992, and May 25, 2021, was conducted. Ulcerated NL (UNL, n = 83) and non-ulcerated NL (NUNL, n = 233) groups were compared. RESULTS Twenty-six percent (83/316) of patients with NL experienced ulceration. UNL was significantly more likely to be painful (52% vs. 36%, P = 0.01), was more likely to have a lesion-associated cutaneous malignancy (7% vs. 0%, P < 0.001), and had a larger median size (7 vs. 5 cm, P = 0.004) compared to NUNL. Vascular studies were performed on a subset of patients and revealed transcutaneous oxygen pressure (TcPO2) < 40 mm Hg in 53% and venous insufficiency in 62% with no significant differences between UNL and NUNL groups. In patients with unilateral ulceration, mean TcPO2 values (39.7 vs. 46.6 mm Hg), regional perfusion index <0.6 (29% vs. 14%), and TcPO2 < 40 mm Hg (43% vs. 14%) were worse in the ulcerated leg compared to the non-ulcerated leg, but these differences were not statistically significant. CONCLUSIONS UNL was more likely to be painful, develop lesion-associated malignancy, and be larger in size compared to NUNL. There were no statistically significant differences in venous insufficiency, arterial Doppler/ankle brachial index, or TcPO2 values between UNL and NUNL patients, however, a significant portion of the cohort demonstrated abnormal vascular studies, particularly on TcPO2 and venous insufficiency testing.

Abstract
Epidermal function is regulated by numerous exogenous and endogenous factors, including age, psychological stress, certain skin disorders, ultraviolet irradiation and pollution, and epidermal function itself can regulate cutaneous and extracutaneous functions. The biophysical properties of the stratum corneum reflect the status of both epidermal function and systemic conditions. Type 2 diabetes in both murine models and humans displays alterations in epidermal functions, including reduced levels of stratum corneum hydration and increased epidermal permeability as well as delayed permeability barrier recovery, which can all provoke and exacerbate cutaneous inflammation. Because inflammation plays a pathogenic role in type 2 diabetes, a therapy that improves epidermal functions could be an alternative approach to mitigating type 2 diabetes and its associated cutaneous disorders.

Abstract
BACKGROUND Diabetic peripheral neuropathy (DPN) is known to predict foot ulceration, lower-extremity amputation and mortality. Patients with diabetes mellitus have a predisposition toward developing chronic inflammatory demyelinating polyneuropathy, and this may also facilitate the formation of diabetic foot and cutaneous impairment, which are considered one of the most serious impairments of diabetes mellitus, with a prevalence of 4-10% in this population. Biomarkers research provides opportunities for the early diagnosis of these complications for specific treatments useful to prevent amputation and, therefore, physical inability and mental disturbance. The recent literature has suggested that glycemic levels may be a novel factor in the pathogenesis of diabetic foot complications and is an important mediator of axonal dysfunction. The aim of this systematic literary review is to determine whether hemoglobin A1c (HbA1c) is a positive predictor for diabetic foot peripheral neuropathy and its complications, such as foot cutaneous impairments. There is a lack of consensus regarding the effect of glycemic variability on diabetic foot peripheral neuropathy, unlike other complications such as retinopathy, nephropathy or micro/macrovascular pathology Methods: Relevant articles were searched in the Medline database using PubMed and Scopus and relevant keywords. The primary search terms used were "glycated hemoglobin" OR "HbA1c" AND "diabetic neuropathies" AND "Foot". RESULTS A number of articles (336) were initially identified while searching the scientific literature regarding this topic, and 32 articles were selected and included in this review. CONCLUSIONS This review highlights the role of HbA1c in diabetic foot peripheral neuropathy. Biomarkers play an important role in the decision-making process, and HbA1c levels are extensively used for diabetic foot clinical outcomes and settings, but biomarker research in diabetic foot peripheral neuropathy is in its infancy and will require careful attention to a number of factors and associations, since the consequences of DPN also include neurological alterations. HbA1c is an accurate and easy-to-administer test and can be an effective biomarker in establishing the diagnosis of diabetes, but future research should focus on standardizing the HbA1c level and selecting which DPN value and its correlated complications, such as foot cutaneous impairments, are the most informative.

Abstract
BACKGROUND AND OBJECTIVE Diabetes mellitus is a common disorder amounting to 400 million patients worldwide. It is often accompanied by a number of complications, including neuropathy, nephropathy, and cardiovascular diseases. For example, peripheral neuropathy is present among 20-30% of diabetics before the diagnosis is substantiated. For this reason, a reliable detection method for diabetic complications is crucial and attracts a lot of research attention. METHODS In this paper, we introduce a non-invasive detection framework for patients with diabetic complications that only requires short video recordings of faces from a standard commercial camera. We employed multiple image processing and pattern recognition techniques to process video frames, extract relevant information, and predict the health status. To evaluate our framework, we collected a dataset of 114 video files from diabetic patients, who were diagnosed with diabetes for years and 60 video files from the control group. Extracted features from videos were tested using two conceptually different classifiers. RESULTS We found that our proposed framework correctly identifies patients with diabetic complications with 92.86% accuracy, 100% sensitivity, and 80% specificity. CONCLUSIONS Our study brings a novel perspective on diagnosis procedures in this field. We used multiple techniques from image processing, pattern recognition, and machine learning to robustly process video frames and predict the health status of our subjects with high efficiency.

Abstract
BACKGROUND Clinical skin manifestations are common in diabetes; however, molecular mechanisms underlying such defects are largely unknown. Several findings indicate a role for microRNAs (miRNAs) in skin homeostasis. OBJECTIVE To investigate whether miRNA expression is altered in diabetic skin. METHODS Type 1 and 2 mouse models of diabetes were used. MiRNA profiling was performed on RNA extracted from the skin of type 1 diabetic mice and non-diabetic controls. Expression levels of pri-miRNAs and of miRNA-biogenesis genes were also analyzed. Biogenesis gene expression analysis was performed in human dermal fibroblasts cultured in hyperglycemic, hypoxic or oxidative stress conditions. RESULTS Several miRNAs were differentially expressed in diabetic skin with a general down-modulation as compared to controls. Bioinformatics analysis of signature-miRNA target genes showed the enrichment in pathways involved in skin homeostasis, such as TGF-β and Wnt. MiRNA alteration in diabetic skin associated with reduced expression levels of DROSHA, DGCR8, XPO5, DICER1, AGO2, both as mRNA and protein. Reduced biogenesis gene expression did not correlate with accumulation of pri-miRNAs, which displayed differences in expression levels similar to those found for their mature miRNAs. Experiments with cultured fibroblasts showed that hypoxia and oxidative stress induced the down-regulation of miRNA-biogenesis genes in this skin cell type. CONCLUSION A general down-regulation of differentially expressed miRNAs was found in diabetic skin. This alteration is part of and is dependent from a wider transcriptional defect also affecting the expression of pri-miRNAs and of genes responsible for miRNA biogenesis. Such an alteration is likely contributing to diabetic skin manifestations.

Abstract
Se estima que en Colombia hay 2.836.500 adultos con diabetes, una enfermedad con una prevalencia del 8,4 %. La exposición a niveles elevados de glucosa afecta los procesos de proliferación y diferenciación en las células de todos los órganos y tejidos, así mismo en los queratinocitos, fibroblastos y demás células presentes en la piel, alteraciones que ocurren en más de un tercio de los diabéticos y que pueden ser la manifestación inicial de la enfermedad. La frecuencia y presentación de estas dermatosis varía según la población estudiada. La dermopatía diabética, la acantosis nigricans, los fibromas laxos, el prurito y la xerosis son las formas más comunes y se consideran marcadores cutáneos de la diabetes. La presente revisión se enfoca en las manifestaciones dermatológicas específicas y no específicas de la diabetes, así como en las relacionadas con su tratamiento. Estas pueden ser un reflejo del estado metabólico actual o previo del paciente diabético y su oportuna identificación permite orientar el diagnóstico primario, sospechar un estado rediabético u optimizar el tratamiento de la enfermedad en los individuos ya diagnosticados.

Abstract
INTRODUCTION This study was intended to assess the efficacy and safety of a rosehip seed oil (RHO) extract in the prevention and treatment of skin lesions in the hands of patients with type 1 diabetes mellitus (T1DM) caused by finger prick blood glucose monitoring. PATIENTS AND METHOD A prospective, randomized, controlled, open-label, rater-blinded trial in patients aged 6-17 years with T1DM and intensive blood glucose control (≥7 finger pricks daily) for 12 days. Three main variables (erythema, skin thickening, and loss of skin integrity) were assessed using a scale ranging from 0 (absent) to 3 (severe involvement). The study was approved by the ethics committee of the hospital. RESULTS Sixty-eight children, and thus 136 hands, were included; 80 hands received rosehip seed oil and 56 hands acted as controls. Baseline characteristics of both groups were similar, with 76.3% and 78.6% of the hands respectively showing skin lesions at study start. Median final global assessment was 0.10 (0.03; 0.30) in the group that received rosehip seed oil and 0.06 (0.00; 0.23) in the control group. A statistically significant improvement in global assessment was found in the control group (P=0.049). No significant differences were found when the medians of the other main variables were compared. No adverse effects were recorded. CONCLUSION A high prevalence of skin lesions secondary to finger prick glucose monitoring, most of them mild lesions, was found at study start. Treatment with rosehip seed oil was safe and was not effective for improving skin lesions.

Abstract
Background Diabetes mellitus (DM) is an interdisciplinary disorder that needs many different specialties' attention; however, the importance of dermatologists' knowledge has not been highlighted regarding this issue. As a result, we aim to assess the prevalence and variety of DM skin and nail manifestations in an effort to further acquaint dermatologists and other clinicians with diabetic dermatologic manifestations. Methods This was a cross-sectional study; subjects who had a diagnosis of DM, attending to the outpatient endocrinology clinics of Rassoul Akram Hospital, Tehran, Iran, were evaluated by one dermatologist for diabetic dermopathy. The results were recorded in prepared data sheets, and general descriptions of DM duration, DM type, DM control, and drug history as well as the demographic data were gathered. Results Among a total of 255 subjects, the prevalence of one or more identifiable skin conditions was 88.4%. 15.7% of the subjects had nail manifestations. Among cutaneous manifestations, acanthosis nigricans, acral erythema, and onychoschizia showed a significant relationship with the age and disease duration (p<0.05); and knuckle pebbles, eczema, facial erythema, and koilonychias had a meaningful relationship with FBS level and glycated hemoglobin, HbA1c (p<0.05). Conclusion This study provides an overview that facilitates earlier detection and treatment of DM. Also, this data can help physicians and endocrinologists to visualize DM control level.

J Diabetes Res 2019; 2019:4583895. [PMID: 31565656 PMCID: PMC6745171 DOI: 10.1155/2019/4583895] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Accepted: 07/09/2019] [Indexed: 01/28/2023] Open
Abstract
AIM (1) To quantify the invisible variations of facial erythema that occur as the blood flows in and out of the face of diabetic patients, during the blood pulse wave using an innovative image processing method, on videos recorded with a conventional digital camera and (2) to determine whether this "unveiled" facial red coloration and its periodic variations present specific characteristics in diabetic patients different from those in control subjects. METHODS We video recorded the faces of 20 diabetic patients with peripheral neuropathy, retinopathy, and/or nephropathy and 10 nondiabetic control subjects, using a Canon EOS camera, for 240 s. Only one participant presented visible facial erythema. We applied novel image processing methods to make the facial redness and its variations visible and automatically detected and extracted the redness intensity of eight facial patches, from each frame. We compared average and standard deviations of redness in the two groups using t-tests. RESULTS Facial redness varies, imperceptibly and periodically, between redder and paler, following the heart pulsation. This variation is consistently and significantly larger in diabetic patients compared to controls (p value < 0.001). CONCLUSIONS Our study and its results (i.e., larger variations of facial redness with the heartbeats in diabetic patients) are unprecedented. One limitation is the sample size. Confirmation in a larger study would ground the development of a noninvasive cost-effective automatic tool for early detection of diabetic complications, based on measuring invisible redness variations, by image processing of facial videos captured at home with the patient's smartphone.

Abstract
Introduction: The search for and creation of drugs with dermatoprotective and metabotropic activity is one of the priorities of modern diabetology. Synthetic organophosphorus compounds with no anticholinesterase activity, to which Dimephosphone belongs to, deserve great attention in this respect.
Materials and Methods: Experiments included 355 white non-linear male mice (18-34 g) and 799 male rats (150–305 g). The dermatoprotective activity (DPA) of Dimephosphone regarding the survival of a skin graft was studied against the background of normoglycemia, as well as against the background of experimental diabetes complicated by hypercholesterolemia. The study of microhemodynamics in the skin was performed using laser Doppler flowmetry. The effects on metabolic processes and the antioxidant system were studied by determining the levels of glucose, urea, creatinine, total bilirubin, total cholesterol, triglycerides, total protein, albumin, globulin, catalase, malondialdehyde, superoxide dismutase, glutathione reductase, glutathione and glutathione peroxidase.
Results: Dimephosphone has a pronounced DPA in conditions of reduced blood circulation against the background of normoglycemia and experimental (alloxan) diabetes complicated by exogenous hypercholesterolemia. By DPA, in most cases against the background of normoglycemia Dimephosphone exceeds Actovegine, is comparable to or inferior to Trental and Mexidol, and is more significant in terms of the therapeutic width than all the drugs taken for comparison.
Discussion: According to the obtained data , DPA of Dimephosphone may be due to its ability to exhibit significant vasodilating, antihypoxic, antioxidant, antiaggregant, membrane-stabilizing, anti-acidotic, antimicrobial and other properties and also to exert a normalizing effect on carbohydrate, protein, lipid and energy metabolism
Conclusion: Dimephosphone can be recommended for further preclinical and clinical studies in the form of various dosage forms, as well as in a combination therapy for metabolic disorders.

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.

A steroid like phytochemical Antcin M is an anti-aging reagent that eliminates hyperglycemia-accelerated premature senescence in dermal fibroblasts by direct activation of Nrf2 and SIRT-1. Oncotarget 2016; 7:62836-62861. [PMID: 27542238 PMCID: PMC5325331 DOI: 10.18632/oncotarget.11229] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2016] [Accepted: 07/27/2016] [Indexed: 12/14/2022] Open
Abstract
The present study revealed the anti-aging properties of antcin M (ANM) and elucidated the molecular mechanism underlying the effects. We found that exposure of human normal dermal fibroblasts (HNDFs) to high-glucose (HG, 30 mM) for 3 days, accelerated G0/G1 phase arrest and senescence. Indeed, co-treatment with ANM (10 µM) significantly attenuated HG-induced growth arrest and promoted cell proliferation. Further molecular analysis revealed that ANM blocked the HG-induced reduction in G1-S transition regulatory proteins such as cyclin D, cyclin E, CDK4, CDK6, CDK2 and protein retinoblastoma (pRb). In addition, treatment with ANM eliminated HG-induced reactive oxygen species (ROS) through the induction of anti-oxidant genes, HO-1 and NQO-1 via transcriptional activation of Nrf2. Moreover, treatment with ANM abolished HG-induced SIPS as evidenced by reduced senescence-associated β-galactosidase (SA-β-gal) activity. This effect was further confirmed by reduction in senescence-associated marker proteins including, p21CIP1, p16INK4A, and p53/FoxO1 acetylation. Also, the HG-induced decline in aging-related marker protein SMP30 was rescued by ANM. Furthermore, treatment with ANM increased SIRT-1 expression, and prevented SIRT-1 depletion. This protection was consistent with inhibition of SIRT-1 phosphorylation at Ser47 followed by blocking its upstream kinases, p38 MAPK and JNK/SAPK. Further analysis revealed that ANM partially protected HG-induced senescence in SIRT-1 silenced cells. A similar effect was also observed in Nrf2 silenced cells. However, a complete loss of protection was observed in both Nrf2 and SIRT-1 knockdown cells suggesting that both induction of Nrf2-mediated anti-oxidant defense and SIRT-1-mediated deacetylation activity contribute to the anti-aging properties of ANM in vitro. Result of in vivo studies shows that ANM-treated C. elegens exhibits an increased survival rate during HG-induced oxidative stress insult. Furthermore, ANM significantly extended the life span of C. elegans. Taken together, our results suggest the potential application of ANM in age-related diseases or as a preventive reagent against aging process.

Abstract
Alterations of the collagen, the major structural protein in skin, contribute significantly to human skin connective tissue aging. As aged-appearing skin is more common in diabetes, here we investigated the molecular basis of aged-appearing skin in diabetes. Among all known human matrix metalloproteinases (MMPs), diabetic skin shows elevated levels of MMP-1 and MMP-2. Laser capture microdissection (LCM) coupled real-time PCR indicated that elevated MMPs in diabetic skin were primarily expressed in the dermis. Furthermore, diabetic skin shows increased lysyl oxidase (LOX) expression and higher cross-linked collagens. Atomic force microscopy (AFM) further indicated that collagen fibrils were fragmented/disorganized, and key mechanical properties of traction force and tensile strength were increased in diabetic skin, compared to intact/well-organized collagen fibrils in non-diabetic skin. In in vitro tissue culture system, multiple MMPs including MMP-1 and MM-2 were induced by high glucose (25 mM) exposure to isolated primary human skin dermal fibroblasts, the major cells responsible for collagen homeostasis in skin. The elevation of MMPs and LOX over the years is thought to result in the accumulation of fragmented and cross-linked collagen, and thus impairs dermal collagen structural integrity and mechanical properties in diabetes. Our data partially explain why old-looking skin is more common in diabetic patients.

Abstract
BACKGROUNDS Diabetes mellitus (DM) is a common endocrine disorder and an increasing epidemic worldwide. Proportional diabetic patients eventually develop cutaneous diseases. OBJECTIVES This study determined the statistical association of cutaneous manifestations and DM as well as the DM-associated cutaneous manifestations in elderly male residents. METHODS A cross-sectional study was conducted in a Veterans Home in Taiwan. The cutaneous manifestations and major systemic diseases of the residents were recorded separately. Univariate logistic regression and multivariate analysis after adjustment for age, body mass index and significant major systemic diseases provided odds ratios and P values for the statistical association. RESULTS A total of 313 male residents (age ≥65 years) were recruited, including 70 (22.4%) with DM. Their most common cutaneous manifestations included fungal infection (77%) and brown spots on the legs (38.3%). Chronic ulcers adjusted odds ratios (AOR 4.90, 95%CI: 1.82-13.19; P = 0.002), brown spots on the legs (AOR 6.82, 95%CI: 3.60-12.89; P < 0.001) and pruritus (AOR 12.86, 95%CI: 4.40-37.59; P < 0.001) were significantly associated with DM. The diabetic residents were inclined to have chronic ulcers, brown spots on the legs and pruritus at a 7.46-fold higher risk (AOR 7.46, 95%CI: 3.86-14.43; P < 0.001). The diabetic residents exhibited marginally higher risks of bacterial infection, scabies, or skin tags. CONCLUSION The DM-associated cutaneous manifestations were chronic ulcers, brown spots on the legs, and pruritus. By observing clues of diabetic cutaneous features, a more complete condition of diabetic patients can be appreciated. The information is essential for providing appropriate treatment and key nursing points regarding the diabetes-associated skin diseases.

Abstract
Bullosis diabeticorum is considered a rare skin manifestation of diabetes mellitus. Tense blisters appear rapidly, mostly on the feet, the cause of which is unclear, with multiple pathophysiologies hypothesised. This is a retrospective review of 4 diabetic patients who presented over six months with diabetic bullae; the condition may therefore not be as rare as commonly believed. All the patients had early surgical debridement followed by topical negative pressure wound dressings. A multidisciplinary team that included vascular surgeons, diabetologists, diabetic foot care team, wound care team, physiotherapists and occupational therapists managed the patients and none of them required amputations. We propose an alternative way of managing these patients with early surgical debridement followed by topical negative pressure wound dressing.

Abstract
Obesity and diabetes are chronic diseases that affect people all over the world, and their incidence is increasing in both children and adults. Clinically, they affect a number of organs, including the skin. The cutaneous manifestations caused or aggravated by obesity and diabetes are varied and usually bear some relation to the time that has elapsed since the onset of the disease. They include soft fibromas, acanthosis nigricans, striae, xerosis, keratosis pilaris, plantar hyperkeratosis, fungal and bacterial skin infections, granuloma annulare, necrobiosis lipoidica, psoriasis, and atopic dermatitis. In this review article we present the skin changes found in children with diabetes mellitus and obesity and related syndromes and highlight the importance of the skin as a tool for establishing clinical suspicion and early diagnosis of systemic disease.

Abstract
BACKGROUND The relationship between skin diseases and extracutaneous complications in diabetes mellitus (DM) is unclear. OBJECTIVE We aimed to investigate the relationship between skin disorders and diabetic neuropathy, nephropathy, and retinopathy in patients with DM. METHODS A total of 750 patients with DM were prospectively enrolled. Demographic and clinical features, skin disorders, glycosylated hemoglobin (HbA1c) levels, and presence of nephropathy, neuropathy, and retinopathy were noted. RESULTS Of the patients, 38.0% had neuropathy, 23.3% had nephropathy, and 22.9% had retinopathy. Any skin disorder was present in 79.2% (n = 594) of patients. The most common skin manifestations were cutaneous infections (47.5%), xerosis (26.4%), and inflammatory skin diseases (20.7%). The frequency of cutaneous infections, fungal infections, diabetic foot, rubeosis faciei, and pigmented purpuric dermatitis was higher in patients with nephropathy than in those without nephropathy. Cutaneous infections, diabetic foot, rubeosis faciei, and diabetic dermopathy were more common in patients with neuropathy. Fungal infections, diabetic foot, rubeosis faciei, diabetic dermopathy, and pigmented purpuric dermatitis were more frequent in patients with retinopathy. Patients with HbA1c ≥8 mmol/mL had more skin disorders than those with HbA1c <8 mmol/mL (P < 0.05 for all). CONCLUSION Skin disorders may be clues to the presence of associated microvascular complications of DM.

Abstract
Chronic medical conditions such as type 2 diabetes may alter the body's normal response to heat. Evidence suggests that the local heat loss response of skin blood flow (SkBF) is affected by diabetes-related impairments in both endothelium-dependent and non-endothelium-dependent mechanisms, resulting in lower elevations in SkBF in response to a heat or pharmacological stimulus. Thermoregulatory sweating may also be diminished by type 2 diabetes, impairing the body's ability to transfer heat from its core to the environment. Diabetes-associated co-morbidities and the medications (particularly those affecting fluid balance) required to treat these conditions may exacerbate the risk of heat-related illness by decreasing SkBF and sweating further. Unfortunately, the majority of studies measure local heat loss responses in the hands and feet and lack measures of core temperature. Therefore, the impact of these impairments on whole-body heat loss remains unknown. This review addresses heat-related vulnerability in individuals with type 2 diabetes by examining the literature related to heat loss responses in this population. Type 2 diabetes, its associated co-morbidities, and the medications required in their treatment may cause dehydration, lower SkBF, and reduced sweating, which could consequently impair thermoregulation. This effect is most evident in individuals with poor blood glucose control. Although type 2 diabetes can be associated with impairments in SkBF and sweating, more physically active individuals requiring fewer medications and having good blood glucose control may be able to tolerate heat as well as those of similar age and body composition.

Abstract
Optical microangiography (OMAG) and Doppler optical microangiography (DOMAG) are two non-invasive techniques capable of determining the tissue microstructural content, microvasculature angiography, and blood flow velocity and direction. These techniques were used to visualize the acute and chronic microvascular and tissue responses upon an injury in vivo. A tissue wound was induced using a 0.5 mm biopsy punch on a mouse pinna. The changes in the microangiography, blood flow velocity and direction were quantified for the acute (<30 min) wound response and the changes in the tissue structure and microangiography were determined for the chronic wound response (30 min–60 days). The initial wound triggered recruitment of peripheral capillaries, as well as redirection of main arterial and venous blood flow within 3 min. The complex vascular networks and new vessel formation were quantified during the chronic response using fractal dimension. The highest rate of wound closure occurred between days 8 and 22. The vessel tortuosity increased during this time suggesting angiogenesis. Taken together, these data signify that OMAG has the capability to track acute and chronic changes in blood flow, microangiography and structure during wound healing. The use of OMAG has great potential to improve our understanding of vascular and tissue responses to injury in order to develop more effective therapeutics.
