North American Clinical Practice Guidelines for the Medical Management of Hidradenitis Suppurativa in Special Patient Populations.

Background: Hidradenitis suppurativa (HS) affects different patient populations that require unique considerations in their management. However, no HS guidelines for these populations exist.

Objective: To provide evidence-based consensus recommendations for patients with HS in seven special patient populations: i) pregnancy, ii) breastfeeding, iii) pediatrics, iv) malignancy, v) tuberculosis infection, vi) hepatitis B or C infection, and vii) HIV disease.

The Role of Patient- and Drug-Related Factors in Oral Minoxidil and Pericardial Effusion: Analyses of Data From the United States Food and Drug Administration Adverse Event Reporting System.

Background: While oral minoxidil (OM) has been associated with pericardial effusion (PE), its etiology is presently inconclusive.

Aims: We characterized patient- and drug-related factors across reports from the United States Food and Drug Administration Adverse Event Reporting System (FAERS) for PE and OM.

Methods: Our observation period spanned 18.

From Viral Infection to Skin Affliction: Unveiling Mechanisms of Cutaneous Manifestations in COVID-19 and Post-COVID Conditions.

COVID-19 skin manifestations are multifaceted, ranging from urticaria, morbilliform or papulovesicular rash, livedoid purpuric lesions, and to pseudochilblains (also called COVID toes). Recent insights into the mechanism of these manifestations have highlighted that morbilliform, papulovesicular, and livedoid/purpuric rashes are related to virus-induced endothelial cell damage and linked to moderate-to-severe disease, whereas pseudochilblains are related to an exaggerated IFN-1 production by plasmacytoid dendritic cells in protected individuals. In this paper, we will review the clinical and physiopathological features of cutaneous COVID-19 manifestations in relation to the direct viral cytopathic effects and dysregulated IFN-1 responses.

Hidradenitis Suppurativa and Maternal and Offspring Outcomes.

Importance: Hidradenitis suppurativa (HS) is associated with morbidity in persons of reproductive age, but the effect on maternal and offspring outcomes is understudied.

Objective: To determine the association of HS with pregnancy outcomes and maternal and child morbidity in the long term.

Design, Setting, And Participants: This population-based longitudinal cohort study with up to 16 years of follow-up took place between 2006 and 2022 in Quebec, Canada.

Prevalence and Predictors of Inflammatory Arthritis in Hidradenitis Suppurativa.

Hidradenitis Suppurativa (HS) is a chronic, debilitating, auto-inflammatory condition often associated with inflammatory arthritis, significantly impacting patients' quality of life. Early diagnosis of both conditions is crucial for optimal management. The objective of this study was to determine the prevalence and factors associated with the development of inflammatory arthritis among HS patients.

Imaging Mass Cytometry in Psoriatic Disease Reveals Immune Profile Heterogeneity in Skin and Synovial Tissue.

Imaging mass cytometry is a technology that enables comprehensive analysis of cellular phenotypes at the tissue level. We performed a multiparameter characterization of structural and immune cell populations in psoriatic skin and synovial tissue samples aimed at characterizing immune cell differences in patients with psoriasis and psoriatic arthritis. A panel of 33 antibodies was used to stain selected immune and structural cell populations.

Low-Dose Oral Minoxidil and Associated Adverse Events: Analyses of the FDA Adverse Event Reporting System (FAERS) With a Focus on Pericardial Effusions.

Background: Low-dose oral minoxidil (LDOM) is used to treat hair loss, but the literature on its safety profile is relatively sparse.

Aims: Using the FDA Adverse Event Reporting System (FAERS) database, we determined signals for adverse events (AEs) with LDOM use.

Methods: Four sets of case/noncase study disproportionality analyses were conducted to determine reporting odds ratio (ROR) for 10 AEs including pericardial effusion (PE).

Prevalence of Musculoskeletal Symptoms in Patients With Hidradenitis Suppurativa and Associated Factors: Cross-Sectional Study.

The prevalence of and factors associated with musculoskeletal (MSK) symptoms in patients with hidradenitis suppurativa (HS) have yet to be elucidated. Given the association between HS and inflammatory comorbidities, understanding the burden of MSK symptoms in patients with HS is crucial for patient-centered care. Our objective was to describe the prevalence of and factors associated with MSK symptoms in patients with HS.

Antifungal resistance in dermatophytes - review of the epidemiology, diagnostic challenges and treatment strategies for managing infections.

Introduction: There is an increasing number of reports of infections. This species is usually poorly responsive to terbinafine.

Areas Covered: A literature search was conducted in May 2024.
