Acne tarda is defined as acne that develops (late-onset acne) or continues (persistent acne) after 25 years of age. The disease is more common in women. The etiology of acne tarda is still controversial, and a variety of factors such as endocrinological disorders including hyperandrogenism and hyperandrogenemia, stress, modern western diet, ultraviolet irradiation, drugs and cosmetics have been implicated. In particular, women with acne tarda and other symptoms of hyperandrogenism such as hirsutism and androgenetic alopecia have a high probability of endocrine abnormalities such as polycystic ovarian syndrome, primary ovarian insufficiency, Cushing’s syndrome and late-onset adrenogenital syndrome. Virilization is a relatively uncommon feature of hyperandrogenemia and its presence often suggests an androgen-producing tumor. Treatment is similar to that of acne in adolescence; however, long-term treatment over years or decades may be required. A thorough history, a focused clinical examination and an interdisciplinary approach together with gynecologists and endocrinologists are extremely helpful in diagnostic evaluation and therapy of patients with acne tarda.

X-ray diffraction is one of the powerful tools in the study of a variety of structures in the stratum corneum at the molecular level. Resolving structural modifications during functioning is an important subject for clarifying the mechanism of operating principles in the function. Here, the X-ray diffraction experimental techniques used in the structural study on the stratum corneum are widely and deeply reviewed from a perspective fundamental to the application. Three typical topics obtained from the X-ray diffraction experiments are introduced. The first subject is concerned with the disruption and the recovery of the intercellular lipid structure in the stratum corneum. The second subject is to solve the moisturizing mechanism at the molecular level and the maintenance of normal condition with moisturizer, being studied with special attention to the structure of soft keratin in the corneocytes in the stratum corneum. The third subject is the so-called 500 Da rule in the penetration of drugs or cosmetics into skin, with attention paid to the disordered intercellular lipid structure in the stratum corneum.

There is increasing evidence of adverse events associated with the use of COVID-19 vaccines. Here, we report a case of the SARS-CoV-2-vaccination-related onset of pityriasis rubra pilaris (PRP) and provide an analysis of previously reported cases in the medical literature. A 67-year-old male presented with a 1-year history of histopathologically proven PRP that first developed 14 days after receiving a COVID-19 booster vaccination. Skin symptoms improved under ustekinumab medication after unsuccessful previous treatment approaches using systemic corticosteroids, brodalumab, and risankizumab. Among the published cases of post-COVID vaccination PRP, 12 (75%) males and 4 (25%) females were reported. The median age of the reported patients was 59 years. In 10 out of 16 patients (62.5%), PRP was diagnosed after the first vaccine dose, in 4 (25%) after the second dose, and in 2 of 15 patients (12.5%) after the third dose. The median time between COVID-19 vaccination and the onset of PRP was 9.5 days (range: 3–60 days). The majority of patients required systemic treatment, including systemic retinoids and methotrexate. PRP might be a rare adverse event after COVID-19 vaccination, particularly affecting older males. Even though most reported patients with COVID-19-vaccination-related PRP could be successfully treated with PRP standard medications, therapy refractory cases may also occur. Thus, clinicians must be aware of this rare but potentially severe complication.

Cutaneous squamous cell carcinoma (cSCC) is one of the most prevalent neoplasms worldwide. Important risk factors for cSCC include sun exposure, immunosuppression, pale skin, and aging. White people are more likely to develop cSCC, and men are more affected than women. In advanced cases, surgery and/or radiotherapy are no longer effective. Due to a historical lack of treatment options, some medications have been used in these patients without sufficient recommendation. There is an urgent need to identify patients at an increased risk of recurrence and spread early for timely diagnosis and treatment. Despite extensive data on the high-risk features and prognostication, considerable variation remains globally regarding high-risk cSCC and the delivery of oncology services. The current comprehensive review evaluated and summarized contemporary knowledge of various management options for cSCC to simplify the integrated treatment plans.

The high metastasis and mortality rates of melanoma in the era of chemotherapy have decreased significantly over the last 10 years. The success is owed largely to the introduction of targeted therapy of oncogenes and immunotherapies, such as checkpoint inhibitors. The aim of the present retrospective, monocentric study is to investigate the impact of chemotherapy or immunotherapy in 550 patients with metastatic melanoma between the years of 2010 and 2019, looking at overall survival while considering BRAF/NRAS/c-KIT mutation status. A total of 17 patients were found to have a c-KIT mutation in exon 11, 13 or 17, including 58.3% with acral lentiginous melanoma, with 53% localized primarily in the lower limbs. In 13.3% of the 231 NRAS-mutated melanomas, primary tumor location was found to be in UV-exposed skin such as on the head and neck, thus about 50% lower than in the 302 patients with wild-type (BRAF-/NRAS-/cKIT-negative) melanoma. Patients with NRAS-mutated melanomas had a significantly lower probability of survival compared to patients with wild-type melanomas, irrespective of the recommendations of the clinical guideline on drug therapy for metastatic melanoma that have been in force since 2010. In contrast to patients with wild-type melanoma who showed a higher probability of survival receiving immune checkpoint inhibitors, the overall survival of patients with NRAS-mutated metastatic melanoma was not more favorable after therapy with immune checkpoint inhibitors compared to chemotherapy treatment.

The effects of orally consumed probiotics on skin wrinkles and dryness are not fully known. A randomized, placebo-controlled, triple-blinded study was conducted with 148 healthy Korean female volunteers aged between 33 and 60 years, who were administered 1.75 × 109 colony-forming units (CFUs) of Bifidobacterium animalis subsp. lactis Bl-04 (Bl-04) (N = 74) or matching placebo (N = 74) for 12 weeks. Facial wrinkles (with 3-dimensional (3D) imaging), skin hydration, transepidermal water loss (TEWL), elasticity, and gloss were assessed at baseline and after every 4 weeks of the intervention. Questionnaire-based subjective evaluations of product efficacy and usability were also analyzed. The consumption of Bl-04 was safe and ameliorated significantly facial skin wrinkle parameters (total wrinkle area and volume, average depth of wrinkles, and arithmetic average roughness (Ra)) versus placebo at 4 weeks, but there were no differences at Week 8 or 12 between groups. Skin hydration, TEWL, elasticity, and gloss were similar between treatment groups, as were the subjective evaluation scores. Oral consumption of Bl-04 indicated promising short-term effects on skin appearance from the winter toward the spring. In future study designs, special attention should be paid to environmental conditions as well as to the skin condition and age of the participants.

The purpose was to evaluate the prognostic performance of the derived neutrophil–to-lymphocyte ratio (dNLR) in patients with metastatic cutaneous melanoma (CM) treated with immune checkpoint inhibitors (ICI). We retrospectively investigated 41 CM patients with stage IV disease who had the indication for treatment with ICI. dNLR as well as NLR were routinely determined prior to the start of ICI treatment. The dNLR and NLR were calculated as follows: dNLR = absolute neutrophil counts (ANC)/white blood cell count −ANC and NRL = ANC/absolute lymphocyte counts, respectively. Follow-up of the patients was performed in line with current guidelines. In univariate analysis, dNLR (p = 0.027 and p = 0.032) as well as NLR (p = 0.0023 and p = 0.0036) were the only parameters which were significantly associated with the best overall response (BOR) and disease control rate (DCR) on ROC curve analyses. NLR negatively correlated with CM-specific survival (r = −0.32, p = 0.043). CM-specific deaths were significantly associated with the absence of immune-related adverse events (p = 0.043), elevated S100 calcium-binding protein B (S100B) at baseline (p = 0.0006), and dNLR (p = 0.024). In multivariate analyses, NLR was the only significant independent predictor for BOR (p = 0.014; odds ratio: 1.7; and 95% CI 1.11 to 2.61) and DCR (p = 0.019; odds ratio: 1.5; and 95% CI 1.07 to 2.19). Regarding CM-specific death, however, normal baseline S100B was the only significant independent predictor (p = 0.0020; odds ratio: 0.074; and 95% CI 0.014 to 0.38) for survival. Our data demonstrate that baseline NLR seems to be superior to dNLR in the prediction of ICI response in CM patients.

Immune checkpoint inhibitors (ICI) and other antineoplastic treatment regimens can trigger cutaneous immune-related adverse events (irAEs). There is a tendency for underreporting of such cases, as cutaneous irAEs are typically perceived as mild and transient. However, more serious cutaneous irAEs can occur which, despite their lower frequency, deserve attention and require specific care. Here, we report a case of extensive hyperpigmented scleroderma-like lesions (SLL) on the lower extremities under combination treatment with pembrolizumab and pemetrexed in a patient with metastatic non-small cell lung cancer. The present case in conjunction with a review of the current literature underscores the potential risk of developing SLL under treatment with anti-PD-1 antibody and/or pemetrexed. Moreover, it is possible that this particular combination treatment synergistically increases the risk of SLL. As a result, more such cases may arise in the future, as ICI/pemetrexed combination treatment might be employed more often. As drug-induced SLL usually require systemic treatment with high dose-corticosteroids, physicians should be aware of SLL as an irAE when cancer patients present with sclerotic and/or fibrotic skin lesions.

As the skin is an accessible organ and many dermatological diagnostics still rely on the visual examination and palpation of the lesions, dermatology could be dramatically impacted by augmented and virtual reality technologies. If the emergence of such tools raised enormous interest in the dermatological community, we must admit that augmented and virtual reality have not experienced the same breakthrough in dermatology as they have in surgery. In this article, we investigate the status of such technologies in dermatology and review their current use in education, diagnostics, and dermatologic surgery; additionally, we try to predict how it might evolve in the near future.

About 20% of patients with systemic sclerosis have symptoms of another connective tissue disease (CTD). Interstitial lung disease (ILD) is one of the most common organ manifestations in systemic sclerosis (SSc) as well as viral illnesses, such as COVID-19, and can lead not only to diffuse alveolar damage, but also trigger an exacerbation of fibrosis among patients with preexisting ILD. It is also associated with substantial morbidity and mortality. According to the World Scleroderma Foundation, SSc-ILD can mask or mimic early COVID-19 lesions and there are no available computed tomography guidelines on how to discern those two conditions. We present a case of systemic sclerosis exacerbation after COVID-19 in a patient with SSc-Lupus Overlap Syndrome.

Interstitial lung disease (ILD) is one of the most common organ manifestations in systemic sclerosis (SSc) as well as viral illnesses, such as COVID-19, and can lead not only to diffuse alveolar damage, but also trigger an exacerbation of fibrosis among patients with preexisting ILD. It is also associated with substantial morbidity and mortality. According to the World Scleroderma Foundation, SSc-ILD can mask or mimic early COVID-19 lesions and there are no available computed tomography guidelines on how to discern those two conditions. We present a case of systemic sclerosis exacerbation after COVID-19 in a patient with SSc-Lupus Overlap Syndrome.","PeriodicalId":11115,"journal":{"name":"Dermato-Endocrinology","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78693244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
