ABSTRACT
BACKGROUND: Contact allergy and atopic dermatitis (AD) are both common inflammatory T cell-mediated diseases and many factors may influence the prevalence of contact allergy in AD patients. In children, their possible correlation was debated with conflicting results. OBJECTIVES: The present study aimed to assess the prevalence of contact sensitivity in children and to investigate the association with AD. MATERIALS AND METHODS: A retrospective multicentre study on children aged from 0 to 14 years patch tested between January 2017 and December 2018 was performed. Children were consecutively patch tested with the SIDAPA (Società Italiana Dermatologia Allergologica Professionale Ambientale) baseline series. RESULTS: Among the 432 children investigated for contact allergy, 125 (28.9%) showed a positive reaction to at least one of the allergens tested, with a higher prevalence of positive patch test reactions in girls (32.3%) than in boys (25.0%). The most frequent contact allergens were nickel sulphate (10.2%), cobalt chloride (6.7%), methylisothiazolinone (3.7%), fragrance mix-2 (3.2%), potassium dichromate (2.8%), fragrance mix-1 (2.1%) and methylchloroisothiazolinone/methylisothiazolinone (2.1%). One-hundred-three children (23.8%) suffered from AD showing a higher prevalence of positive patch test (36.9%) compared to children without AD (26.4%). CONCLUSIONS: Despite the topic being still controversial, the present study suggests a consistent prevalence of contact allergy among children with higher sensitivity rate among children with AD than without AD.

An increasing use of beta-blockers in dermatology has been described over the last 10 years, despite the fact that their use in diseases other than infantile hemangiomas is off-label. This review discusses the emerging role of topical beta-blockers in the treatment of infantile hemangioma, but also pyogenic granuloma, Kaposi sarcoma, wounds and nail paronychia. Data in literature demonstrate that topical beta-blockers are a safe and valid therapeutic option in numerous cutaneous diseases. Side effects are mainly restricted to the application site. Further studies and randomized trials may contribute to reinforce the role of topical beta-blockers in the dermatological armamentarium.

Autosomal recessive congenital ichthyoses (ARCI) are characterized by generalized skin scaling, hyperkeratosis, erythroderma, and disabling features affecting the skin (palmoplantar keratoderma, fissures, pain, itch), eyes, ears, and joints. Disease severity and chronicity, patient disfigurement, and time and costs required for care impose a major burden on quality of life. This multicentre cross-sectional study investigated the impact of ARCI on quality of life of patients and families, using the Dermatology Life Quality Index (DLQI), the Children DLQI (CDLQI) and Family Burden of Ichthyosis (FBI) questionnaires. Disease severity was assessed by a dermatologist. A total of 94 patients were recruited, of whom 52 (55.3%) children. Mean age was 20.1 (median 13.5) years. The mean CDLQI/DLQI score was 7.8, and 21 patients scored >10, indicating a major impairment in quality of life: symptoms, feelings and treatment problems were the most affected domains of quality of life. FBI showed a major repercussion on psychological factors and work. The results of this study highlight the impact of ARCI on specific aspects of patient and family life, underlining the need for psychological support.

Allergic and immunologic skin diseases negatively impact the quality of life (QoL) of affected patients with detrimental consequences. Nonetheless, in everyday clinical practice the evaluation of QoL is often overlooked. Considering the increasing prevalence of atopic dermatitis, allergic contact dermatitis, hereditary angioedema, cutaneous mastocytosis, and urticaria, it is essential to determine the effects of allergic and immunologic skin diseases on QoL. A joint meeting (GET TOGETHER 2021) of the Italian Society of Allergology, Asthma and Clinical Immunology (SIAAIC) and the Italian Society of Allergological, Occupational and Environmental Dermatology (SIDAPA) aimed to summarize the features of the main QoL tools used in these diseases and to describe the extent of QoL impairment as well as the impact of treatments on QoL, particularly biologic therapies. The assessment of QoL in patients with allergic and immunologic skin diseases relies on generic, organ-specific and disease-specific questionnaires. While generic and organ-specific questionnaires allow comparison between different diseases, disease-specific questionnaires are designed and validated for specific cohorts: the QoL Index for Atopic Dermatitis (QoLIAD) and the Childhood Atopic Dermatitis Impact Scale (CADIS) in atopic dermatitis, the ACD-11 in allergic contact dermatitis, the Angioedema QoL Questionnaire (AE-QoL) and the Hereditary Angioedema QoL questionnaire (HAE-QoL) in hereditary angioedema, the Mastocytosis QoL Questionnaires (MCQoL e MQLQ) in cutaneous mastocytosis, and the Chronic Urticaria QoL questionnaire (CU-Q2oL) in urticaria. Among the many factors that variably contribute to QoL impairment, pruritus can represent the leading cause of patient discomfort. Biologic therapies significantly ameliorate QoL in atopic dermatitis, hereditary angioedema, mastocytosis and chronic urticaria. In general, adequate management strategies are essential for improving QoL in patients with allergic and immunologic skin diseases.
ABSTRACT
Topical antibiotic therapy is a central component of patient management for several skin conditions, including acne, hidradenitis suppurativa, rosacea, impetigo or other superinfected dermatitis, and prevention of wound infections. Moreover, particular situations, such as skin diseases of bacterial origin in pregnancy and infants often warrant topical therapy. However, the occurrence of local delayed hypersensitivity reactions and the rising rate of antibiotic resistance are becoming great challenges faced by many dermatologists today. This narrative review provides an overview of the main topical antibiotics used in dermatology, focusing on their clinical role in the most common dermatological indications. For this purpose, a review of MEDLINE and PubMed for pertinent, scientific, and clinical publications until March 2020 was performed. Only articles published in the English language were included.

The objective of this study is to determine drug effectiveness and safety of the tumor necrosis factor-alpha blocker monoclonal antibody adalimumab in a real-life cohort of 54 children and/or adolescents with severe plaque psoriasis. Retrospective, multicenter analysis over a 52-week period is discussed in this study. Efficacy was determined by the percentage of patients achieving Psoriasis Area Severity Index (PASI 75) and PASI 90 at weeks 16, 24, and 52 and the response in biologic-naïve versus non-naïve patients. Safety was assessed by the number of patients experiencing at least one adverse event. At week 16, 29.6% of patients achieved a 90% PASI score reduction (PASI 90), while 55.5% of patients achieved a 75% PASI score reduction (PASI 75). Effectiveness was sustained through week 24, since PASI 90 response increased to 55.5% and PASI 75 response increased to 74.0% of patients. The PASI response rates did not differ between biologic-naïve and non-naïve patients. The drug was well tolerated and no serious infections were observed. Adalimumab was effective and safe in this cohort of children with severe plaque psoriasis in a 52-week observation. Effectiveness did not differ between biologic-naïve and non-naïve patients.

The aim of this retrospective study was to determine the type and prevalence of vascular patterns in the ulcerated and non-ulcerated portions of histologically proven basal cell carcinomas (BCCs) and correlate them with other dermoscopic and clinical features, including the clinically supposed diagnosis. Three authors retrospectively collected 156 clinical and 156 dermoscopic digital images of ulcerated BCCs (histologically confirmed); each image was blindly evaluated by 2 other authors, who did not know the histological diagnosis. Seventeen lesions were completely ulcerated, while 139 lesions presented ulcerated and non-ulcerated portions. Correct clinical diagnosis was associated with the type of lesion, in particular 90.6% of partially ulcerated lesions were correctly diagnosed with clinical-dermoscopic examination, compared with 11.8% of totally ulcerated lesions (χ2 = 64.00, p = 0.000). Presence of arborizing pattern in the ulcerated portion was associated with a correct diagnosis (Fisher's exact test, p = 0.015). Correct diagnosis was also associated with absence of dotted pattern in the non-ulcerated area (χ2 = 16.18, p = 0.000); the absence of hairpin (χ2 = 6.08, p = 0.000) and glomerular patterns were associated with correct diagnosis in the ulcerated areas (χ2 = 18.64, p = 0.000). In case of completely ulcerated BCC the clinician lacks the means to correctly identify the correct nature of the lesion, and is driven towards an incorrect diagnostic conclusion.

Psoriasis (Ps) is a chronic-relapsing, inflammatory, and proliferative condition of the skin: prior studies hypothesized a link between Ps and anomalies in ß-adrenergic tone. We therefore aimed to ascertain the prevalence of early repolarization pattern (ERP) in resting electrocardiograms (ECGs) of psoriatic patients compared with an appropriate control group. We performed a retrospective study of resting ECGs of 100 consecutive psoriatic patients and 100 healthy controls. The presence of ERP in at least two contiguous leads at rest ECG was recorded, and findings were also categorized according to the lead group where ERP was detected (anterior, lateral, inferior). An ERP in ≥ 2 contiguous leads occurred in 40 % of psoriatic patients, compared with 14 % of control subjects (p < 0.001). (36 vs 10 % in anterior leads, p < 0.001; 6 vs 3 % in inferior leads, p n.s.; 10 vs 2 % in lateral leads). After adjustment for sex, age, heart rate, and level of physical activity, the odds ratios for the presence of ERP were 8.6 (95 % CI, 2.1-35.2, p < 0.01), and 7.1 (95 % CI, 1.6-31.8, p < 0.05) in anterior leads. In a small case/control study, increased rates of ECGs showing ERP have been observed among psoriatic patients. Clinical significance of such finding needs to be assessed in further observational studies.

BACKGROUND: Acitretin is licensed for and is most commonly used to treat psoriasis. Little information exists about its efficacy and safety in childhood and adolescent psoriasis. METHODS: Retrospective analysis of a group of children and adolescents (<17 years of age) with moderate to severe plaque psoriasis treated with acitretin between 2010 and 2014 at Italian dermatology clinics. Patients were identified through databases or registries. RESULTS: The study population consisted of 18 patients with a median age of 9.5 years at the start of therapy. The median maintenance dosage per day was 0.41 mg/kg. Eight patients (44.4%) achieved complete clearance or good improvement of their psoriasis, defined as improvement from baseline of 75% or more on the Psoriasis Area and Severity Index at week 16. Three had three or more courses of treatment with short disease-free intervals. In three patients, acitretin treatment was ongoing at the time of data collection. The mean total duration of treatment in responders was 22.7 months. One patient discontinued treatment because of arthralgia. The remaining nine patients (50%) discontinued treatment because it was ineffective. Mucocutaneous adverse effects occurred in all patients, but did not affect therapy maintenance. CONCLUSIONS: In this retrospective case series, acitretin was a moderately effective, well-tolerated treatment in children with moderate to severe plaque psoriasis. Given the small number of patients, statements about long-term safety are not possible.

CONTEXT: Alkyl glucosides and alkyl poly-glucosides are widely used as wetting agents, surfactants and emulsifiers in several industrial and cosmetic products. They are known as well-tolerated and are usually added to the primary surfactants in order to reduce the irritating potential of the main foaming agents. OBJECTIVE: Recently, some authors suggested that allergic contact dermatitis to alkyl glucosides might be more frequent than suspected. On the other hand, the chemical structures of glucosides do not show potentially allergenic chemical groups or strongly polarized structures. The aim of our study is to investigate alkyl glucosides carrying out a detailed chemical analysis on samples of raw materials to identify potentially allergenic impurities or by-products contained in commercial samples of alkyl glucosides. MATERIALS AND METHODS: We chemically analyzed samples of cocoyl glucoside, decyl glucoside and lauryl glucoside by three different analytical methods, in order to identify any undesired or polluting substances. RESULT: In each of the three samples, we detected the presence of isobornyl acrylate. Its approximate content in the tested samples is 500 ng/g of the product. DISCUSSION: Isobornyl acrylate is not used in the synthesis of alkyl glucosides, but as a plasticizer in many plastic materials. It can be easily released to materials flowing over these surfaces when they have high extraction power, as glucosides. CONCLUSION: Isobornyl acrylate may play a role as hidden allergen, in the form of an impurity collected during the industrial process, explaining some cases of allergic reaction to alkyl glucosides.

Acne vulgaris is a chronic dermatological disorder that affects the majority of teenagers in the Western world. Topical therapy is widely used to treat mild-moderate acne and is known as well-tolerated thanks to its low systemic toxicity, although associated to skin adverse effects. Acne seems to be associated also to an intrinsic alteration of the epidermal barrier, regarding both the upper and the follicular stratum corneum that promotes the onset of such local side effects. The commonest one is irritant contact dermatitis, an event of frequent observation occurring with erythema, burning, dryness, scaling, and itching, usually characterized by low severity and limited duration. Among topical acne drugs, retinoids are the most irritating ones. Another side effect is allergic contact dermatitis: it is rare and mainly associated to benzoyl peroxide.

BACKGROUND: A non-steroidal, anti-inflammatory moisturizing cream containing rhamnosoft, ceramides, and L-isoleucine (ILE) (pro-AMP cream) has been recently developed for the specific treatment of atopic eczema (AE) of the face. In this trial, we evaluated the clinical efficacy and tolerability of pro-AMP cream in the treatment of facial AE in children in comparison with an emollient cream. METHODS: In a randomized, prospective, assessor-blinded, parallel groups (2:1) controlled trial, 107 children (72 allocated to pro-AMP cream and 35 allocated to control group) with mild-to-moderate chronic AE of the face were enrolled. Treatments were applied twice daily for a 6-week period. Facial Eczema Severity Score (ESS) was evaluated at baseline, week 3, and week 6, by an assessor unaware of treatment allocation. Investigator's Global Assessment (IGA) score was assessed at week 3 and at week 6. Tolerability was evaluated at week 3 and at week 6 using a4-point score (from 0: low tolerability to 3: very good tolerability). RESULTS: At baseline ESS, mean (SD) was 6.1 (2.4) in the pro-AMP cream group and 5.3 (3) in the control group. In the pro-AMP group, in comparison with baseline, ESS was significantly reduced to 2.5 (-59%) after 3 wks and to 1.0 (-84%) at week 6 (p = 0.0001). In the control group, ESS was reduced to 3 (-42%) at week 2 and to 2.6(-50%) at week 6. At week 6, ESS in pro-AMP cream was significantly lower than the control group (1.0 vs. 2.6; p = 0.001). Both products were well tolerated. CONCLUSION: Pro-AMP cream has shown to be effective in the treatment of mild-to moderate chronic lesion of AE of the face. Clinical efficacy was greater in comparison with an emollient cream. ( CLINICAL TRIAL REGISTRY: NTR4084).

Angiotensin II receptor blockers (ARBs) are drugs generally well tolerated. There are few reports about cutaneous side effects of ARBs. The present authors describe herein four cases of purpuric eruption mainly involving sites of friction in patients taking ARBs. These eruptions completely cleared after stopping the drug and implementing preservative measures to reduce friction.
