Polygenic Score: A Tool for Evaluating the Genetic Background of Sporadic Hidradenitis Suppurativa.

Sporadic Hidradenitis Suppurativa (spHS) is a multifactorial disease in which genetic predisposition is intertwined with environmental factors. Due to the still to date limited knowledge of spHS genetics, we calculated Polygenic scores (PGS) to study the genetic underpinnings that contribute to spHS within European demographic. 256 spHS patients and 1686 healthy controls were analyzed across 6 European clinical centers.

Italian National Registry of Alopecia Areata: an epidemiological study of 699 Italian patients.

Background: Alopecia areata (AA) is an organ-specific autoimmune disease that affects the hair follicles of the scalp and the rest of the body causing hair loss. Due to the unpredictable course of AA and the different degrees of severity of hair loss, only a few well-designed clinical studies with a low number of patients are available. Also, there is no specific cure, but topical and systemic anti-inflammatory and immune system suppressant drugs are used for treatment.

"Your Skin Tells You" Campaign for Keratinocyte Cancers: When Individuals' Selection Makes the Difference.

Background: Prevention campaigns for skin cancers have focused primarily on melanoma, and over time there has been increasing awareness of the need to select the population to be screened to maximize program effectiveness.

Objectives: The objective of the study was to report the results of a free dermatological initiative, as part of an awareness campaign dedicated to keratinocyte cancers, targeting individuals pre-selected through a short questionnaire.

Methods: One day of dermatological consultations was held at 15 dermato-oncology referral centers during May 22-June 30, 2021.

Therapeutic strategies for oral lichen planus: State of the art and new insights.

Oral lichen planus (OLP) is a chronic inflammatory disease of the oral mucosa. Several clinical subtypes of OLP have been reported, including the reticular and erosive one. On the one hand, reticular OLP is usually asymptomatic and is characterized by white streaks surrounded by well-defined erythematous borders.

Can Ultrasound Examinations Generate Pain in Hidradenitis Suppurativa Patients? Results from a Multicentric Cross-Sectional Study.

Background: Pain is not a trivial issue for hidradenitis suppurativa (HS) patients and has been considered a domain in the Core Outcome Set. To date, there is no evidence about pain caused by the ultrasound examinations.

Objective: The aim of the study was to assess the presence of pain generated by the ultrasound examinations of HS patients.

Hidradenitis Suppurativa in a Large Cohort of Italian Patients: Evaluation of the Burden of Disease.

Background: Hidradenitis suppurativa (HS) is a chronic, inflammatory, recurrent, debilitating skin disease of the hair follicle that usually occurs after puberty with painful, deep-seated, inflamed nodules and sinus tracts in the apocrine gland-bearing areas of the body, most commonly the axillae and inguinal and anogenital regions, with a relevant impact on patients' quality of life (QoL).

Objective: To evaluate how the burden of HS disease impacts on patient well-being and working activities in a large Italian population over a period of 9 months.

Methods: A multicenter, prospective, epidemiologic cohort study was conducted in adult Italian patients with HS.

Baseline neutrophil/lymphocyte ratio (NLR) and red blood cell distribution width (RDW) correlate with advanced stages in cutaneous squamous cell carcinoma.

Background: The neutrophil/lymphocyte ratio (NLR) and red blood cell distribution width (RDW) at diagnosis have been shown to correlate with advanced disease and to be prognostic factors in many tumors. However, their role as a prognostic factor for cutaneous squamous cell carcinoma (cSCC) has not yet been studied.

Objective: Therefore, the aim of our study was to evaluate the correlation of NLR and RDW with stages of disease in patients with cSCC in order to define whether or not higher values of these two markers correlate with a more aggressive disease.

Digital Myxoid Cysts: Correlation of Initial and Long-Term Response to Steroid Injections.

Background: Digital mucous cysts (DMCs) are benign myxoid pseudocysts that develop on the distal interphalangeal joint's lateral or dorsal aspects. Management consists either of a surgical approach, conservative therapy, or simple follow-up.

Objective: To correlate the initial and long-term response with clinical and ultrasound parameters in DMCs treated with intralesional steroids as first-line therapy.

Ultrasound patterns of localized cutaneous leishmaniasis and clinical correlations.

A single-center retrospective study reviewed the following sonographic features of 18 confirmed cases of localized cutaneous leishmaniasis to identify shared presentation patterns: echotexture, lesion borders, hypodermal involvement, soft-tissue changes, and vascular pattern. A second objective was to correlate these patterns with clinical characteristics, including sex, age, anatomical location, nodule vs. plaque presentation, raised borders, granulation tissue, swelling, hyperkeratotic crusting, disease onset, and healing time.

Scalp hair whorl patterns in patients affected by Neurofibromatosis Type 1: A case-control study.

Background: The hair whorl denotes the spiral disposition of hairs around an axis, which is determined by the follicle growing direction. Atypical variants of scalp hair patterns, identified by abnormally placed or multiple whorls, have been associated with early brain developmental disorders and several dysmorphic syndromes.

Materials And Methods: A 6-month case-control, prospective monocentric study included an overall number of 557 children.

Ultrasound features of the subungual glomus tumor and squamous cell carcinomas.

Background: Nail tumors often pose a significant challenge for the clinician, as they are burdened by a high delay in diagnosis and paucity of clinical signs in the early stage. In most cases, the onset of pain or nail plate dystrophy leads to imaging investigations such as plain radiography, magnetic resonance imaging, and ultrasonography (US) when surgery is pending.

Material And Methods: A 2-year monocentric study evaluated the histologically confirmed cases of subungual glomus tumor (GT) and squamous cell carcinoma (SCC) with a pre-surgical US assessment, and reviewed their sonography features.

Melanocytic lesion in children and adolescents: an Italian observational study.

Malignant melanoma is a rare neoplasm in the pediatric age group. One of the main risks factors is represented by the presence of a high number of melanocytic nevi. Sun exposure in pediatric age represents a predictor of melanocytic nevi number in the adult age and there is a direct correlation between the presence of melanocytic moles in early childhood and the development of many nevi in adults, suggesting that a high number of nevi in childhood should be considered as a predictor of melanoma development during adult life.

Adalimumab Dose Intensification in Recalcitrant Hidradenitis Suppurativa/Acne Inversa.

Background: Adalimumab is the only approved compound for the treatment of adult patients with moderate-to-severe hidradenitis suppurativa (HS) who did not respond to a systemic classical treatment. Despite its significant short- and long-term efficacy, a percentage of patients do not respond sufficiently. Moreover, some primary responders experience a response loss with time.

Clindamycin versus clindamycin plus rifampicin in hidradenitis suppurativa treatment: Clinical and ultrasound observations.

Background: Antibiotics are recognized as first-line treatments for hidradenitis suppurativa (HS), but the data on their efficacy are limited.

Objective: Evaluate the efficacy of oral clindamycin versus that of clindamycin plus rifampicin in patients with HS.

Methods: A total of 60 patients with mild-to-moderate-severe HS who were classified according to their International Hidradenitis Suppurativa Severity Score System (IHS4) and Hurley scores, were subdivided into 2 groups of 30 patients each (group A, the members of which received clindamycin plus rifampicin, and group B, the members of which were treated with clindamycin alone) and retrospectively studied.

AISI: A New Disease Severity Assessment Tool for Hidradenitis Suppurativa.

Introduction: Hidradenitis suppurativa (HS) is a chronic, disabling, skin disorder. Because of renewed scientific interest in HS, different aspects of the condition, such as disease severity assessment, are being investigated and better defined. The aim of this study is to provide a novel tool for the assessment of disease severity.
