Pediatric Patch Testing at Mayo Clinic Between 2016 and 2020.

Allergic contact Dermatitis (ACD) is a common condition within the pediatric population. Patch testing is an important way to identify relevant allergens. To provide an update of the common contact allergens seen in children based on patch testing data at our institution from 2016 to 2020.

Trends in Patch Testing With the Mayo Clinic Standard Series, 2017-2021.

Patch testing to a standard series is used to identify culprit allergens in patients with contact dermatitis. The reaction rates evolve over time based on trends in cutaneous exposures by the general population. The aim of this study was to analyze the patch test results of the Mayo Clinic standard series in patients tested from 2017 to 2021.

Cutaneous involvement in VEXAS syndrome: clinical and histopathologic findings.

Background: VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome is an autoinflammatory disease with frequent cutaneous manifestations.

Methods: We conducted a retrospective study of all patients with genetically confirmed VEXAS syndrome seen at our institution. Available clinical photographs and skin biopsy slides were reviewed.

The spectrum of pediatric scarring alopecia: A retrospective review of 27 patients seen at Mayo Clinic.

Background/objective: There are few studies examining pediatric scarring alopecia. The objective of this study is to characterize the clinicopathologic findings, comorbidities, and treatment outcomes of pediatric patients with scarring alopecia.

Methods: Retrospective review of patients under age 18 diagnosed with scarring alopecia at Mayo Clinic from 01/01/1992 through 02/05/2019.

Lichen planopilaris in men: a retrospective clinicopathologic study of 19 patients.

Background: Lichen planopilaris (LPP) is a scarring alopecia rarely described in men.

Objective: To investigate the clinical and histopathologic features of LPP in men.

Methods: We performed a retrospective cohort study of male patients with LPP seen at Mayo Clinic between 1992 and 2016.

Characteristics of exceptional responders to autologous stem cell transplantation in multiple myeloma.

Autologous stem cell transplantation (ASCT) is an important treatment modality in multiple myeloma (MM). However, relapse following ASCT is considered almost inevitable. This study aimed to characterize exceptional responders to ASCT, defined as progression-free survival (PFS) >8 years in the absence of maintenance therapy.

Lichen Planopilaris in Women: A Retrospective Review of 232 Women Seen at Mayo Clinic From 1992 to 2016.

Objective: To characterize the clinicopathologic findings, comorbidities, and treatment outcomes of women with lichen planopilaris (LPP).

Method: In this retrospective review of women with LPP at Mayo Clinic from 1992 to 2016, we searched for scarring alopecia in all female patients aged 1 to 100 years from January 1, 1992, through December 31, 2016. Men were excluded from this study to more accurately determine the association of hormonal factors in LPP pathogenesis.

The Final Patch Test Read: Day 5 or Day >7?

Background: A major question in patch testing is when to perform the final reading. Our current standard practice is to place patches on day 1, remove them on day 3, and perform readings on days 3 and 5. For certain allergens, another reading is performed sometime from days 7 to 14≥.
