Reliability and meaningful change of the Patient-Reported Outcomes Measurement Information System(®) Itch Questionnaire (PIQ) item banks in adults with atopic dermatitis.
The Patient-Reported Outcomes Measurement Information System Itch Questionnaire (PIQ), includes a suite of patient-reported outcome measures to assess the burden of itch in adults. In this study, the investigators sought to determine the smallest detectable change (SDC), threshold for meaningful improvement and test–retest reliability of PIQ item banks for assessing the burden of itch in adult AD.

Hidradenitis Suppurativa Area and Severity Index Revised (HASI-R): psychometric property assessment.
This study’s objective was to assess the reliability and validity of the Hidradenitis suppurative (HS) Area and Severity Index Revised (HASI-R) tool to assess HS severity. This tool incorporates signs of inflammation and body surface area involved while current tools to measure severity relies on lesion counts, which are time-consuming and unreliable. Measurement properties of HASI-R were evaluated. Twenty raters evaluated 15 HS patients in a hospital-based ambulatory dermatology clinic. Inter- and intra-rater reliability of the HASI-R and its components were assessed, as well as its construct and known-groups validity. The HASI-R was found to have moderate inter-rater reliability and the highest intra-rater reliability of all HS severity assessment tools. It also had good construct validity and demonstrated known-groups validity.

Testing strategies and predictors for evaluating immediate and delayed reactions to cephalosporins.
Although 1% to 2% of the general population carries a cephalosporin allergy label (CAL), there is a lack of validated testing strategies and predictors of true allergy. The objective of this study was to identify cross-reactivity patterns and predictors of skin test positive (STP) in geographically disparate patients with a CAL. The investigators found that cephalosporin cross-reactivity was based on shared R1 groupings. Increasing time since the original reaction and the presence of a PAL with unknown cephalosporin tolerance predicted a lower likelihood of cephalosporin STP.
