Genetic polymorphisms to identify patients with an optimal response to tildrakizumab in psoriasis patients from real-life clinical practice.

Detecting the association of genetic variants to the response of biological therapy represents an important advance in developing a personalized therapy. The aim of this work was to study the association of polymorphisms with an optimal response to tildrakizumab in patients with psoriasis in a real-life clinical practice. Ninety patients with plaque psoriasis recruited from-Spanish hospitals receiving tildrakizumab for at least 24 weeks were genotyped for 180 polymorphisms.

Development of a Patient Journey Map for Improving Patient Experience and Quality of Atopic Dermatitis Care.

Introduction: Atopic dermatitis (AD) is a chronic inflammatory skin condition that affects both children and adults. AD increases the risk of developing comorbidities like asthma, allergic rhinitis and food allergies. AD patients face difficulties, including itching, lack of effective treatments, lack of funding and discomfort in seeking a diagnosis or treatment.

Background: The worldwide outbreak of monkeypox has evidenced the usefulness of the dermatologic manifestations for its diagnosis.

Objective: To describe the histopathologic and immunohistochemical findings of monkeypox cutaneous lesions.

Methods: This is a retrospective histopathologic and immunohistochemical study of 20 patients with positive Monkeypox virus DNA polymerase chain reaction and immunohistochemical positivity for Vaccinia virus in cutaneous lesions.

Ustekinumab to guselkumab transitions: A series of 54 patients emulating the navigate trial in real life.

NAVIGATE clinical trial demonstrated a higher rate of Psoriasis Assesment Severity Index (PASI)90 response in patients treated with guselkumab when compared to ustekinumab and an improved response in those who switched from ustekinumab to guselkumab due to partial response. The objective of the study is to describe ustekinumab to guselkumab switching in clinical practice. Observational, multicentric, descriptive study including 54 psoriasis patients who switched to guselkumab after treatment with ustekinumab from March 2019 to February 2021.

Sonography of a case series of talar callosities.

Talar callosity is an uncommon condition characterized by asymptomatic hyperkeratotic plaques located on the dorsum of one or both feet. We have detected an increased number of children presenting with this condition after the COVID-19 lockdown. High-frequency ultrasound was performed in all patients who consulted because of talar callosity.

Discriminative deep learning based benignity/malignancy diagnosis of dermatologic ultrasound skin lesions with pretrained artificial intelligence architecture.

Background: Deep-learning algorithms (DLAs) have been used in artificial intelligence aided ultrasonography diagnosis of thyroid and breast lesions. However, its use has not been described in the case of dermatologic ultrasound lesions. Our purpose was to train a DLA to discriminate benign form malignant lesions in dermatologic ultrasound images.

Dermatologic ultrasound in the management of childhood linear morphea.

Linear morphea is the most common subtype of localized scleroderma in the pediatric population. This condition can be quite disabling, with complications such as growth defects and painful flexion contractures. Assessment of disease progression and early intervention are key to minimize morbidity.

Immunophenotypic Differences in Tumor-Infiltrating Lymphocytes and Neovascularization Between Primary Cutaneous Melanoma With and Without Metastasis: An Immunohistochemical Study of 80 Cases.

The prognostic implications of the immunophenotype of the tumor-infiltrating lymphocytes (TILs) in primary cutaneous melanoma are well known. In recent years, the study of this immunophenotype has also resulted in immunotherapeutic consequences. The aims of this study were to characterize the subpopulations of TILs in primary cutaneous melanoma, in cases with and without metastasis, as well as the neovascularization associated with the primary neoplasm, and its influence on the development of metastasis.

Dermatologic Ultrasound in Primary Care: A New Modality of Teledermatology: A Prospective Multicenter Validation Study.

Objectives: This study aimed to validate dermatologic ultrasound as a complementary teledermatologic imaging modality in primary and tertiary care centers.

Methods: Six primary care centers and 1 tertiary care dermatology department collaborated in the program. Images were sent through the institutional teledermatologic platform to the tertiary care dermatology department.

European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) Position Statement on Dermatologic Ultrasound.

Dermatologic ultrasound is a recent application of ultrasound for the evaluation of healthy skin and appendages and their diseases. Although the scientific literature regarding this application is still not sufficient for evidence-based guidelines, general recommendations issued by scientific societies are necessary. The EFSUMB (European Federation of Societies for Ultrasound in Medicine and Biology) steering committee for dermatologic ultrasound has developed a series of consensus position statements regarding the main fields of dermatologic ultrasound (technical requirement, normal skin and appendages, inflammatory skin diseases, tumoral skin diseases, aesthetic dermatology and practice-training requirements).

Increased Marginal Stiffness Differentiates Infiltrative From Noninfiltrative Cutaneous Basal Cell Carcinomas in the Facial Area: A Prospective Study.

Objectives: Basal cell carcinoma (BCC) is the most common dermatologic malignant skin cancer. Infiltrative histologic variants are more aggressive and require wider surgical margins or Mohs surgery, in contrast with noninfiltrative variants, which are commonly treated with standard surgical excision. Elastography has not been used to date to differentiate between the histologic variants of BCC.

Ex Vivo High-Frequency Ultrasound for Assessment of Basal Cell Carcinoma.

The use of Mohs micrographic surgery for poorly defined cutaneous tumors is present in a few departments in Spain. Reintervention is occasionally necessary when the margins of the surgical specimen are invaded by the tumor. We propose the use of ultrasound to assess these margins by imaging the surgical specimen once excised.

Primary Subcutaneous Synovial Sarcoma: First Reported Subcutaneous Case Showing TLE1 Immunoreactivity.

Synovial sarcoma (SS) accounts for 5%-10% of all soft tissue sarcomas. It is a well-defined soft tissue neoplasm with biphasic and monophasic histologic subtypes and unknown histogenesis. It usually occurs in the extremities, especially the thigh-knee region of young adults.

Vulvar metastatic Crohn disease: clinical, histopathological and ultrasonographic findings.

Metastatic Crohn disease (MCD) is an unusual type of cutaneous Crohn disease characterized by skin lesions separated from the lesions of the gastrointestinal tract. The diagnosis of MCD is essentially histological,showing noncaseating granulomas in the dermis and subcutaneous fat tissue. We report a case of MCD with vulvar involvement and clinical, histopathological, and ultrasonographic findings of this disease.

Cyclosporine Use in Epidermal Necrolysis Is Associated with an Important Mortality Reduction: Evidence from Three Different Approaches.

Several immunomodulatory agents are used in the treatment of epidermal necrolysis, but evidence of their efficacy is limited. The Autonomous Community of Madrid has two reference burn units to which all patients with epidermal necrolysis are referred. One burn unit has mostly used cyclosporine (CsA), and the other has used non-CsA therapies (mainly high-dose intravenous immunoglobulin).

Ultrasound Evaluation as a Complementary Test in Hidradenitis Suppurativa: Proposal of a Standarized Report.

Background: Staging and monitoring of patients with hidradenitis suppurativa (HS) have been traditionally based on clinical findings. However, the physical examination may show important limitations because of its poor sensitivity for differentiating between different lesion subtypes, and its low sensitivity to define the disease's activity.

Objective: To develop a consensus ultrasound (US) report that could summarize the relevant anatomical characteristics and staging of patients considering the experience of radiologists and dermatologists working on imaging of HS.

Introduction of Basic Dermatologic Ultrasound in Undergraduate Medical Education.

Teaching ultrasound procedures to undergraduates has recently been proposed to improve the quality of medical education. We address the impact of applying standardized dermatologic ultrasound teaching to our undergraduates.
