A variety of treatments have been proposed, with inconsistent results. In the last decades, the use of platelet-rich plasma (PRP) is receiving increasing interest as a potential effective technique in the treatment of several dermatological diseases, including vitiligo.Objective: We conducted a review with the aim to identify studies that documented the use of PRP for vitiligo.Materials and Methods: Electronic databases of MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) from inception to November 2019 have been searched using different combinations of the following terms: “platelet-rich plasma”, “platelet gel”, “platelet-rich fibrin”, “PRP” and “vitiligo”.Results: We identified 6 clinical studies consistent with our research, with a total of 253 patients, listing and discussing the obtained results. In all reports, all treated patients showed a stable vitiligo, and a significantly higher improvement in the PRP groups was always observed compared to control groups. Regarding the side effects, PRP in vitiligo patients is useful and without important side effects.Conclusion: PRP is a promising treatment for stable vitiligo lesions in different body sites. The possible use of PRP in combination with traditional therapeutic options and the standardization of processing protocols represents a very fertile field for future research. Larger clinical trials with longer time of observation would provide solid evidence regarding the effectiveness of PRP for the treatment of vitiligo.Keywords: vitiligo, skin, platlet rich plasma, PRP, treatment

Although the clinical benefit of omalizumab has been established in several clinical trials, there are very little data about long-term treatment with this drug and real-life reports regarding its use in patients affected by comorbidities other than urticaria are lacking.Objectives: To assess omalizumab efficacy and safety in a heterogeneous population of patients affected by chronic spontaneous urticaria and several comorbidities in a real-world setting.Materials and methods: Patients affected by chronic spontaneous urticaria with weekly urticaria activity score >16 resistant to antihistamines were treated with omalizumab 300 mg injection as add-on to H1-antihistamines administered every 4 weeks for 6 months. Clinical assessment of weekly urticaria activity score, dermatology life quality index and blood tests were performed at baseline, 12, 24 and 52 weeks of treatment. Response was assessed based on reduction weekly urticaria activity score.Results: Thirty-two patients (22F; 10M) with a mean age of 52.4 years (range 27–72) affected by chronic spontaneous urticaria were enrolled. Comorbidities affecting our study population were divided into 6 categories: cardio-metabolic (77%), oncologic (19%), infectious (16%), allergic (45%) immunologic (41%) and others (18%). Omalizumab determined a satisfactory reduction of symptoms of chronic spontaneous urticaria and an amelioration of quality of life within our population. No relevant alterations regarding patients’ underlying conditions were encountered. This is the first study regarding the use of omalizumab for chronic spontaneous urticaria in a population of adult patients affected by several comorbidities, eg, cardio-metabolic, oncologic, infectious, allergic, immunologic and psychiatric diseases. Real-life data represent a valuable source of information about a drug’s safety and efficacy profile, especially in patients affected by different comorbidities that are widely diffused in Western countries.Keywords: chronic spontaneous urticaria, omalizumab, oncologic, cardiovascular, allergic and immunologic conditions, comorbidities

Psoriasis, Psoriatic Arthritis and Nail psoriasis are chronic diseases that share a common underlying etiology of immunity dysregulation, enhanced activation of inflammatory pathways and remitting-relapsing course. Although nails represent a small percentage of the body surface involvement of this site can lead to impaired quality of life, severe discomfort and even result in permanent disability. Current therapeutic options for nail psoriasis include a variety of topical and systemic treatments although they are often reported as unsatisfactory from patients either due to their poor effectiveness or disturbing side effects. Recently small molecule drugs such as the PDE4 inhibitors were introduced in clinical practice and specifically apremilast has shown to be an effective new treatment option for psoriasis and psoriatic arthritis. Considering either the specific mechanism of action of apremilast, we performed a real-life observational study of 24 weeks assessing apremilast role in nail psoriasis. Patients received apremilast 30mg bid, orally. Safety and efficacy were assessed at weeks 0, 4, 8, 12 and 24 using Dermatologic Life Quality Index (DLQI) and Nail Area Psoriasis Severity Index (NAPSI). At T0 we took a nail sample to investigate the presence of onychomycosis. Culture tests were performed in all the patients to search for fungi. We recruited a total of 15 patients with nail psoriasis. The analysis of variance (one-way ANOVA) showed the following results: DLQI (F.15.7; p-value <.00001) and NAPSI (F.9.4; p-value <.00001). Three patients (20%) presented also onychomycoses at the beginning of the treatment. Apremilast showed fast and sustained improvement of nail psoriasis over time and a complete resolution of life quality impairment due to the disease. [ABSTRACT FROM AUTHOR]

Background : Malignant epithelial nail unit tumors pose significant diagnostic and therapeutic challenges due to their clinical presentation often mimicking benign conditions and due to the need to preserve as much nail unit function as possible during surgery. Early detection is crucial, even if none of these tumors represent a life-threatening disease. Objectives : This review focus on squamous cell carcinoma, verrucous carcinoma, eccrine porocarcinoma, onychocytic carcinoma, basal cell carcinoma, malignant onychopapilloma, malignant onycholemmal cyst and onycholemmal carcinoma. Methods : Existing literature on the aforementioned tumors has been revised and synthesized. Results : Clinical presentation, pathology, diagnostic procedures, risk factors and the challenges associated with surgical management have been described in detail. Conclusions : Malignant epithelial tumors of the nail unit require careful evaluation and management due to their complex presentation. Early detection and an informed surgical approach are essential to improve patient outcomes and minimize complications.

Background: There are few studies, mainly case reports, on the involvement of the nail unit in autoimmune bullous disorders., Summary: Nail involvement in autoimmune bullous disorders is a significant clinical phenomenon, marked by a range of manifestations, most often not presenting with blisters like on the skin but rather with alterations of the nail unit such as paronychia, onychomadesis, or onycholysis. This involvement is particularly notable due to the unique immunological features of the nail unit, including the expression of various antigens and the presence of Langerhans cells. Conditions like pemphigus vulgaris, bullous pemphigoid, epidermolysis bullosa acquisita, linear IgA disease, and bullous systemic lupus erythematosus can lead to nail abnormalities. The prevalence of nail manifestations varies according to the disorder, and diagnosis often relies on histopathological and immunofluorescence testing. Nail involvement correlates with disease severity and duration, sometimes serving as a herald sign. Further research is needed to guide therapeutic approaches for nail involvement in autoimmune bullous diseases., Key Messages: Nail involvement in autoimmune bullous nail disorders may be confusing as there are almost never bullae. One should keep the diagnosis in mind when facing an atypical paronychia., Competing Interests: The authors have no conflicts of interest to declare., (© 2024 S. Karger AG, Basel.)

Introduction: Tinea capitis (TC) is a superficial fungal infection affecting the scalp. The existence of asymptomatic carriers (ACs) could represent a potential reservoir responsible of (re)contamination and failure of treatment. No prospective studies on ACs in household contacts of TC patients in Europe have been published to date., Objectives: The aim of this study was to assess the prevalence of ACs in a cohort of household contacts of children who were diagnosed with TC in the metropolitan area of Bruxelles, Belgium., Methods: This prospective observational study was conducted from October 2015 to April 2016 at the Dermatology Department of the University Hospitals Brugmann, Saint-Pierre, Queen Fabiola Children Hospital., Results: Ninety-nine cases of TC from 95 different family circles were included. The main infectious agent identified was Microsporum audouinii in 53 cases. The mean age of TC patients was 5.8 years. Male/female ratio was 2.8. Eighty-one household contacts of TC patients were enrolled in the study. Two cases of ACs (5%) were identified., Conclusions: M. audouinii was the most common pathogen identified. The prevalence of ACs we report is on average higher compared to other European large cities. Larger prospective studies including all close contacts of affected patients are required in order to establish guidelines regarding identification and management of ACs., Competing Interests: No conflicts of interest., (Copyright © 2021 by S.

Introduction: Psoriasis (PsO), a chronic inflammatory, multisystemic, and multifactorial disease can cause endothelial dysfunction, artery calcification, and atherosclerotic disease. A higher incidence of vascular occlusive events has been observed in psoriatic patients compared to healthy controls, and multiple studies confirm the association between moderate-severe PsO and atherosclerosis, coronary artery calcification, and higher cardiovascular risk., Objective: We sought to analyze atherosclerotic disease prevalence in epiaortic vessels of psoriatic and non-psoriatic patients to understand if PsO could represent an independent risk factor predisposing to atherosclerotic disease., Methods: We evaluated 47 psoriatic patients without cardiovascular risk factors with color Doppler ultrasound (CDUS). If atheromatous plaques were detected, a computed tomography angiography (CTA) was performed. We evaluated 47 non-psoriatic patients without cardiovascular risk factors with CDUS. Atherosclerosis prevalence in both groups were statistically analyzed. CDUS performance was compared to CTA., Results: In the psoriatic group (mean age 50.9 years), 6 had atheromatous plaques and 12 had an intima-media thickness (IMT) > 1 mm (overall prevalence of atherosclerotic disease: 38.2%). All plaques detected with CDUS were confirmed at CTA. In the control group (mean age 51.3 years), CDUS revealed atheromatous plaques in 4 patients and IMT > 1 mm in 4 ones (overall prevalence of 17%). The difference of atherosclerotic disease prevalence between the groups was statistically significant (P < 0.05)., Conclusion: Our results highlight that PsO could be considered a predisposing factor for atherosclerotic disease development in epiaortic vessels, as it causes an increased IMT, that is also considered an independent cardiovascular risk factor., Competing Interests: Competing interests: None., (©2022 Dattola et al.)

Background: The efficacy and safety of certolizumab pegol over 52 weeks was compared in two groups of patients: Group 1 comprised patients naïve to biologic treatments; Group 2 comprised patients previously treated with one or more antitumor necrosis factor (TNF)-α and/or anti-interleukin (IL) agents., Methods: We reported results in 50 patients affected by both mild psoriasis (PsO) and psoriatic arthritis (PsA). Primary endpoint was a reduction from baseline at week 52 of Disease Activity Score (DAS44-ESR) in both groups of patients. Secondary endpoints were a reduction from baseline at week 52 of Psoriasis Area Severity Index (PASI), Visual Analog Scale for Pain (PAIN VAS), ESR, CRP, and Dermatology Life Quality Index (DLQI)., Results: We observed a statistically significant improvement of both cutaneous and rheumatic disease in all patients, with a consistent reduction of DAS44-ESR, PASI, and PAIN VAS from baseline to week 52. DAS44-ESR decreased from 3.9 at BL to 1.5 at W52 (Group 1), and from 3.8 to 1.7 at W52 (Group 2). Mean PASI Score decreased from 3.2 at baseline (BL) to 0.4 at W52 (Group 1), and from 5.4 to 0.7 at W52 (Group 2). Mean PAIN-VAS decreased from a value of 73.5 at BL to 2.5 at W52 (Group 1), and from a value of 62.4 at BL to 9.2 at W52 (Group 2). We also found a reduction in ESR, CRP and DLQI values for each time point., Conclusions: Our results confirm that CZP can be administered safely and effectively to treat both psoriasis and psoriatic arthritis irrespective of previous treatments with biologic agents.

Background : female androgenetic alopecia (FAGA) is a common cause of non-scarring alopecia in women, affecting approximately 40% of women by age 50, bearing a significant psychosocial burden on affected patients. Platelet-rich plasma (PRP) has been widely investigated as a potential effective treatment for several dermatological conditions, including male androgenetic alopecia (MAGA). However, few studies have been conducted focusing on the use of PRP in FAGA. The aim of this review was to identify reports that investigated the use of PRP for the treatment of FAGA. Methods : Electronic databases of MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) from inception to September 2020 have been searched using different combinations of the following terms: "androgenetic alopecia," "FAGA," "female pattern hair loss," "platelet-rich fibrin," "platelet-rich plasma," and "PRP". Results and conclusions : Eight ( n = 8) clinical studies consistent with our research were identified. A total of 197 subjects has been enrolled in the included studies. All of them were adult female patients (mean age: 38.9) affected by female pattern hair loss. PRP is a well-tolerated procedure which showed promising results in males-only and mixed populations of AGA patients. PRP showed to produce high levels of satisfaction and improvement in the quality of life in patients affected by FAGA. In the light of this evidence, PRP may be proposed in patients who did not respond or did not tolerate topical minoxidil, as well as in combination with topical and oral treatments.

Background: Onychomycosis affects 5.5% of the general population and represents up to 50% of all nail diseases. Diagnosis and pathogen identification are essential in order to plan an adequate treatment. Many diagnostic techniques are available, and however, no solid data regarding comparison between different techniques over a large number of specimens are available to date., Objectives: To compare sensitivity and specificity of direct examination, histopathology and fungal culture in our referral mycology laboratory., Methods: Nail specimens received at the cutaneous pathology and mycology laboratory of the University Hospital Saint-Pierre (Brussels, Belgium) between 1 January and 15 May 2018 were retrospectively analysed. All specimens were submitted to direct examination and culture. In cases of adequate specimen size, histopathology was performed. Fungal culture was considered the gold standard for diagnosis., Results: A total of 2245 nail samples were included in the study. Onychomycosis was diagnosed in 1266 specimens. Sensitivity and positive predictive value were found to be higher for direct examination compared to histopathology, while sensitivity of direct examination was found to be lower. Combined approach with all the three techniques showed the highest rate of positivity, followed by the association of direct examination and histopathology., Conclusions: To our knowledge, this study included the largest number of nail specimens to date, allowing a comparison between direct examination, culture and histopathology. Direct examination showed to be the most performing technique in routine practice. Histopathology represents the most effective option in cases where both specimen size and laboratory resources are adequate. Our paper adds to the literature the 'real-life' experience of the mycology laboratory of a referral centre for nail diseases., (© 2020 Wiley-VCH GmbH.)

Main subtypes of cutaneous lupus erythematosus are represented by acute, subacute cutaneous, intermittent and chronic cutaneous lupus erythematosus. Discoid lupus erythematosus represents the most common phenotype of chronic cutaneous lupus erythematosus. The spectrum of clinical manifestations mirrors that of several and distinct histopathological features. Such variability among different CLE subtypes is also observed at dermoscopy. Dermoscopy is nowadays considered an additional valuable method for skin lesions assessment in general dermatology, following and completing the well-known clinical diagnostic steps, such as medical history and clinical examination. In vivo reflectance confocal microscopy (RCM) is a non-invasive imaging tool able to assess the epidermis and upper dermis producing high resolution (horizontal ∼1.25 μm, vertical ∼5 μm), en face tissue sections used for melanocytic and inflammatory evaluation. In this study, we reported dermoscopic and RCM features about 9 patients affected by subacute and chronic lupus erythematosus retrospectively analyzed.

Introduction: We report a case of a young female patient, previously affected by psoriatic arthritis, and treated with adalimumab, who developed a chronic spontaneous urticaria and started a concomitant therapy with omalizumab. Methods & results: A 50% reduction of the Dermatology Life Quality Index (from 7 at baseline to 4 in weeks 12 and 24) and a complete reset of the Urticaria Activity Score for 7 days (from 27 at baseline to 0 in weeks 12 and 24) were recorded. During all treatment with omalizumab, administering of adalimumab was continued. Due to complete control of urticaria symptoms, the patient stopped treatment with omalizumab after 24 weeks. Conclusion: The combination of adalimumab and omalizumab could offer a favorable efficacy and safety profile. The synergistic action of the two biological drugs in reducing systemic inflammation could be responsible for a shorter time to obtain clinical response.

Background: Depression and anxiety are the most common psychiatric comorbidities in chronic spontaneous urticaria (CSU). Omalizumab is a monoclonal antibody approved for CSU treatment. We evaluated the prevalence of anxiety and depression in CSU patients before and after treatment with omalizumab., Materials & Methods: A total of 30 patients were enrolled in the study: 15 patients affected by CSU and treated with omalizumab and the other 15 healthy subjects did not receive any systemic therapy. All patients were evaluated using Hospital Anxiety and Depression Scale, CRP and erythrocyte sedimentation rate, at baseline and after 6 months., Results: The omalizumab group after 6 months of therapy had a decrease of all the scores and biomarkers., Conclusion: Omalizumab allowed an improvement of urticaria and mental comorbidities., Competing Interests: Financial & competing interests disclosure The authors have no relevant affiliations or financial involvement with any organization or entity with a financial interest in or financial conflict with the subject matter or materials discussed in the manuscript.

Although trichoscopic criteria indicative of disease severity and inflammatory activity have been recently proposed, the potential use of reflectance confocal microscopy (RCM) in the evaluation of the inflammatory stage of FD has never been published to date. Our study investigated RCM features of 14 patients with a histopathological diagnosis of FD, evaluating clinical and trichoscopic findings. RCM findings were divided into 2 main patterns: "follicular" and "interfollicular." Our results suggest a potential role for RCM as a noninvasive, fast technique for a complementary investigation in the diagnostic process, as well as in the therapeutic management decision., Competing Interests: The authors have no conflicts of interest to declare., (Copyright © 2020 by S.

We present the results on retrospective analysis about the efficacy of Certolizumab pegol (CZP), an antitumor necrosis factor-alpha agent, as monotherapy on skin psoriasis (PsO) in patients affect both by psoriatic arthritis (PsA) and mild-severe PsO. To date, the CZP is authorized for the treatment of PsA, PsO beyond that rheumatoid arthritis, axial spondyloarthritis/ankylosing spondylitis, and Crohn's. Assessments included an evaluation of the Psoriasis Area and Severity Index (PASI). Twelve patients (9M and 3F mean age 57.8 ± 8 years) were enrolled in our study. Nine patients had been previously treated with others biologic agents, three patients were naïve. Clinical and laboratory evaluations including PASI, erythrosedimentation rate, and C-reactive protein were performed at baseline (BL), at Week 12 (W12), Week 24 (W24), and Week 52 (W52) of treatment. Although the combination between methotrexate and CZP is allowed, we included, in our study, patients treated only with CZP. In such a way as to be as specific as possible, topical corticosteroids, vitamin D derivatives, retinoid creams, anthralin derivatives as well as p-UVA or UV-B have been forbidden to enrolled patients. With the same purpose, all the patients used the identical moisturizing cream two times a day. Mean PASI score decreased from 18 (BL) to 0 (W52) as follows: 18 at BL, 4 at W12, 0 at W24, and 0 at W52. Severe adverse events were not reported. Safety evaluations were performed every 3 months: liver and renal functions were monitored in all patients during the treatment, and no patient presented abnormal values. To the best of our knowledge, this is the first report that highlights the efficacy of CZP as monotherapy in psoriasis with mild to severe cutaneous involvement. Although to date the drug is authorized only for PsA, our results demonstrate that CZP is safe and effective on both cutaneous and joint components representing, therefore, an effective option in the treatment of cutaneous symptoms of PsO. Limitations of our study are presented by the relatively short observation time (W52) and by numeric small study group. Long-term data with a larger number of enrolled patients are necessary in order to confirm our preliminary observations., (© 2020 Wiley Periodicals LLC.)

Background: Yellow nail syndrome is a rare condition characterized by typical nail alterations and variable presence of lymphedema and respiratory disease. The pathogenesis is still obscure, with most of the literature deriving from case reports and few investigations. The most reported respiratory conditions associated with yellow nail syndrome are pleural effusion and bronchiectasis, whereas association with rhinosinusitis is rarer., Objectives: To describe a case of yellow nail syndrome and to provide a literature review regarding this disorder, discussing pathogenetic hypothesis, associated conditions, and therapeutic options., Patients/methods: A 49-year-old man presented with arrested growth and alterations of his nails, without any history of previous trauma or inflammation but with a severe nasal septum deviation and a history of chronic rhinosinusitis. A diagnosis of yellow nail syndrome was made., Results: Six months after undergoing rhinoseptoplasty and treatment with oral vitamin E, the patient's nails were cured., Conclusions: This case emphasizes the role of the dermatologist in detecting systemic conditions. The correct diagnosis led to complete resolution of both nail alterations and associated respiratory disorders., Competing Interests: Competing interests: The authors have no conflicts of interest to disclose., (©2020 Vollono et al.)

The management and prognosis of squamous cell carcinoma largely depend on its invasiveness and grade of differentiation. Pigmented nail fold squamous cell carcinoma represents a therapeutic challenge, needing careful treatment to preserve nail function.

Curcumin is a compound isolated from turmeric, a plant known for its medicinal use. Recently, there is a growing interest in the medical community in identifying novel, low-cost, safe molecules that may be used in the treatment of inflammatory and neoplastic diseases. An increasing amount of evidence suggests that curcumin may represent an effective agent in the treatment of several skin conditions. We examined the most relevant in vitro and in vivo studies published to date regarding the use of curcumin in inflammatory, neoplastic, and infectious skin diseases, providing information on its bioavailability and safety profile. Moreover, we performed a computational analysis about curcumin's interaction towards the major enzymatic targets identified in the literature. Our results suggest that curcumin may represent a low-cost, well-tolerated, effective agent in the treatment of skin diseases. However, bypass of limitations of its in vivo use (low oral bioavailability, metabolism) is essential in order to conduct larger clinical trials that could confirm these observations. The possible use of curcumin in combination with traditional drugs and the formulations of novel delivery systems represent a very promising field for future applicative research.

Objective: Sinonasal adenocarcinoma is a tumor typically associated with exposure to occupational carcinogens. The International Agency for Research on Cancer (IARC) published several data in order to classify carcinogenic power of physical-chemical agents as far as sinonasal cancer is concerned., Materials and Methods: We report a clinical case of sinonasal adenocarcinoma observed in an 84 years old patient, without clinical history of past exposure to carcinogens, smoke and alcohol., Results and Conclusions: A sinonasal adenocarcinoma in a patient without risk factors is extremely rare. It is very important to recognize this cancer at an early stage in order to give better survival rates to the patients., Key Words: Carcinogens, Intestinal-type adenocarcinoma, Sinonasal cancer.
