Multiple diagnostic tools are used to evaluate psoriasis and atopic dermatitis (AD) severity, but most of them are based on subjective components. Transepidermal water loss (TEWL) and temperature are skin barrier function parameters that can be objectively measured and could help clinicians to evaluate disease severity accurately. Thus, the aims of this study are: (1) to compare skin barrier function between healthy skin, psoriatic skin and AD skin; and (2) to assess if skin barrier function parameters could predict disease severity. A cross-sectional study was designed, and epidermal barrier function parameters were measured. The study included 314 participants: 157 healthy individuals, 92 psoriatic patients, and 65 atopic dermatitis patients. TEWL was significantly higher, while stratum corneum hydration (SCH) (8.71 vs. 38.43 vs. 44.39 Arbitrary Units (AU)) was lower at psoriatic plaques than at uninvolved psoriatic skin and healthy controls. Patients with both TEWL > 13.85 g·m−2h−1 and temperature > 30.85 °C presented a moderate/severe psoriasis (psoriasis area severity index (PASI) ≥ 7), with a specificity of 76.3%. TEWL (28.68 vs. 13.15 vs. 11.60 g·m−2 h−1) and temperature were significantly higher, while SCH (25.20 vs. 40.95 vs. 50.73 AU) was lower at AD eczematous lesions than uninvolved AD skin and healthy controls. Patients with a temperature > 31.75 °C presented a moderate/severe AD (SCORing Atopic Dermatitis (SCORAD) ≥ 37) with a sensitivity of 81.8%. In conclusion, temperature and TEWL values may help clinicians to determine disease severity and select patients who need intensive treatment.

Background: Hidradenitis suppurativa (HS) has a high impact on quality of life. However, sexual health has scarcely been investigated. Objective: To describe the frequency of sexual dysfunction (SD) in women and erectile dysfunction (ED) in men with HS and to explore potential risk factors. Patients and Methods:We conducted a cross-sectional study using a crowd-sourced online questionnaire spread by the Spanish hidradenitis suppurativa patients’ association (ASENDHI). Results: In total, 393 participants answered the questionnaire. SD was found in 51% (95% CI 45–57%) of women and ED in 60% (95% CI 49–70%) of men. Factors related to SD were education status, patient’s global assessment for disease activity, numeric rating scale for pain and unpleasant odour and the absence of a stable relationship. Factors related to ED were increasing age, the presence of active lesions in the genital area and the number of areas affected by active lesions. Conclusions: There is a high prevalence of SD and ED in HS patients. Being in a stable relationship has been a protective factor of SD in women. The results suggest that sexual impairment in HS patients is due, at least in part, to disease activity, symptoms and active lesions.

Hidradenitis suppurativa (HS) is a chronic auto-inflammatory skin disease with a great impact in quality of life. However, there is little research about the impact of HS on sex life. The aims of this study are to describe the frequency of sexual distress (SD) in patients with HS and to explore potentially associated epidemiological and clinical factors. We conducted a cross-sectional study by means of a crowd-sourced online questionnaire hosted by the Spanish hidradenitis suppurativa patients’ association (ASENDHI). Sexual distress (SD) was evaluated with a Numeric Rating Scale (NRS) for HS impact on sex life. A total of 393 participants answered the questionnaire. The mean NRS for HS impact on sex life was 7.24 (2.77) in women and 6.39 (3.44) in men (p < 0.05). Variables significantly associated (p < 0.05) with SD in the multiple linear regression model were sex, with a higher risk in females, the presence of active lesions in the groin and genitals and NRS for pain and unpleasant odor; being in a stable relationship was an important protector factor. Regarding these results, it seems that SD in HS patients is due, at least in part, to disease symptoms and active lesions in specific locations, emphasizing the importance of disease control with a proper treatment according to management guidelines. Women and single patients are more likely to suffer from sexual distress.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a global pandemic that has spread all over the word. To avoid the virus transmission, healthcare workers (HCWs) must wear adequate personal protective equipment (PPE). PPE is associated with several side events, including skin reactions. The objective of this study is to summarize the prevalence, type and risk factors for cutaneous adverse events related to PPE and prevention measures to avoid them. A systematic review and metanalysis was conducted using Medline, Scopus and Embase databases from conception to 21 st January 2021. All types of epidemiological studies regarding skin adverse events related to PPE were included. The literature search identified 1,007 references, 35 of them met the eligible criteria and were included for analysis, representing 31,453 participants. The media of skin side events related to PPE was 75.13%. The rate of cutaneous adverse events related to mask was 57.71% and those associated with gloves and hand hygiene products was 49.16%.Most common skin adverse events were contact dermatitis, acne and itching. The most damaged anatomical regions were the nasal bridge, the cheeks and the hands. The duration of PPE wearing was the most common risk factor. Frequent hand washing, gloves and masks were the agents most frequently related to skin reactions. N95 respirators were the most harmful mask type for the skin.Hydrocolloid use prevented from developing skin adverse events related to masks. In conclusion, the rate of cutaneous adverse events related to PPE use is high. A longer duration of PPE wearing was the most common risk factor. Using hydrocolloid could prevent from skin injuries related to mask use.

Scientific evidence shows that psoriasis patients have a higher risk of sexual dysfunction as compared to the general population. The risk of erectile dysfunction is also higher in psoriasis patients. The risk factors associated with sexual dysfunction in psoriasis patients are disease severity, female gender, psoriatic arthritis and age.

The new coronavirus SARS-CoV-2 is associated with a wide variety of cutaneous manifestations. While new skin manifestations caused by COVID-19 are continuously being described, other cutaneous entities should also be considered in the differential diagnosis, including adverse cutaneous reactions to drugs used in the treatment of COVID-19 infections. The aim of this review is to provide dermatologists with an overview of the cutaneous side effects associated with the most frequently prescribed drugs in patients with COVID-19. The skin reactions of antimalarials (chloroquine and hydroxychloroquine), antivirals (lopinavir/ritonavir, ribavirin +/- interferon, oseltamivir, remdesivir, favipiravir and darunavir) and treatments for complications (imatinib, tocilizumab, anakinra, immunoglobulins, corticosteroids, colchicine and low molecular weight heparins) are analyzed. Information regarding possible skin reactions, their frequency, management and key points for differential diagnosis are presented.

Purpose of review To provide an update of vascular malformation syndromes by reviewing the most recent articles on the topic and following the new International Society for the Study of Vascular Anomalies (ISSVA) 2018 classification. Recent findings This review discusses the main features and diagnostic approaches of the vascular malformation syndromes, the new genetic findings and the new therapeutic strategies developed in recent months. Summary Some vascular malformations can be associated with other anomalies, such as tissue overgrowth. PIK3CA-related overgrowth spectrum (PROS) is a group of rare genetic disorders with asymmetric overgrowth caused by somatic mosaic mutations in PI3K-AKT-mTOR pathway that encompass a heterogeneous group of rare disorder that are associated with the appearance of overgrowth. CLOVES syndrome and Klippel–Trénaunay syndrome are PROS disease. Proteus syndrome is an overgrowth syndrome caused by a somatic activating mutation in AKT1. CLOVES, Klippel–Trénaunay and Proteus syndromes are associated with high risk of thrombosis and pulmonary embolism. Hereditary hemorrhagic telangiectasia is an autosomic dominant disorder characterized by the presence of arteriovenous malformations. New therapeutic strategies with bevacizumab and thalidomide have been employed with promising results.
