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.

Association of itch triggers with atopic dermatitis severity and course in adults.
Atopic dermatitis (AD) is associated with heterogeneous triggers of itch, which may affect AD course and severity. The objective of this study was to characterize the triggers of itch in adult AD. The investigators concluded that itch triggers were common and affected the course of AD. They noted that itch triggers are an important end point to assess in patients with AD.

Product of Investigator Global Assessment and Body Surface Area (IGAxBSA): a practice-friendly alternative to the eczema area and severity index to assess atopic dermatitis severity in children.
Accurately documenting pediatric atopic dermatitis (AD) severity is important, but research tools, such as Eczema Area and Severity Index (EASI), are too time consuming for clinical settings. The objective of this study was to evaluate an Investigator Global Assessment and body surface area product (IGA×BSA) as an easy-to-use severity measure for pediatric AD. The investigators concluded that the IGA×BSA (using the vIGA) is a simple measure that correlates well with the EASI in patients with mild to severe pediatric AD.

The EGS grading scale for skin and soft-tissue infections is predictive of poor outcomes: a multicenter validation study.
Using the hypothesis that the grading scale used for emergency general surgery (EGS) diseases would be predictive of complications, length of stay, and mortality in skin and soft-tissue infections (STIs), this multi-institutional study sought to validate the grading scale by applying it to a different disease process with a higher associated mortality. Data collected from 12 trauma centers included outcomes such as mortality, complications, and length of stay as well as demographic variables and disease characteristics. The EGS scale for STI was used to grade each infection; two surgeons graded each case to evaluate inter-rater reliability. The authors conclude that their validation effort demonstrates that grade IV and V STIs are significantly predictive of these outcomes.

The role and diagnosis of allergic contact dermatitis in patients with atopic dermatitis.
Recent systematic reviews have suggested that allergic contact dermatitis (ACD) is a significant clinical problem in both children and adults with atopic dermatitis (AD). The authors review the clinical scenarios where patch testing is indicated in AD. In addition, they review the contraindications, preferred patch-testing series, pitfalls, and challenges determining the relevance of positive patch-test reactions in AD patients.

Systematic review of diagnostic criteria used in atopic dermatitis randomized controlled trials.
This study sought to determine the most commonly used atopic dermatitis diagnostic criteria in randomized controlled trials internationally. The results highlighted the lack of uniformity and documentation of atopic dermatitis diagnostic criteria in randomized controlled trials for atopic dermatitis. The investigators recommended harmonizing the diagnostic criteria for atopic dermatitis in future randomized controlled trials.

Validation of International Classification of Disease Ninth Revision codes for atopic dermatitis.
This study sought to validate the use of ICD-9-CM codes for identifying atopic dermatitis. It found that in the outpatient setting, the ICD-9-CM codes 691.8 and 692.9 alone have poor positive predictive value (PPV). Incorporation of diagnoses of asthma, hay fever, and food allergy improves PPV and specificity. In the inpatient setting, a primary discharge diagnosis of 691.8 had excellent PPV.

Validation of International Classification of Diseases codes for the epidemiologic study of dermatomyositis.
The authors assessed the validity of using ICD-9-CM code 710.3 to identify adult patients with dermatomyositis in outpatient and inpatient settings. They found that one or more occurrences of ICD-9 code 710.3 is insufficient to support the diagnosis of dermatomyositis in the outpatient setting, but that ICD-9 710.3 codes appear to be valid in the inpatient setting.

Atopic dermatitis, atopic eczema, or eczema? A systematic review, meta-analysis, and recommendation for uniform use of 'atopic dermatitis'.
The authors sought to determine the most commonly-used terms for atopic dermatitis. They found that atopic dermatitis was the most commonly-used term in studies across almost all publication types, languages, and journals and appears to be increasing in popularity. They concluded by suggesting the use of the term atopic dermatitis in publications, healthcare clinician training, and patient education.

Assessment of atopic dermatitis using self-report and caregiver report: a multicentre validation study.
The researchers sought to validate the assessment of self- and caregiver-reported eczema. They performed a prospective multicentre dermatology-practice-based study (three sites) to determine the validity of caregiver- and self-reported ever having eczema and 1-year history of eczema. Their conclusion was that self- and caregiver-reported diagnosis of eczema ever or in the past year based on a single question demonstrated sufficient validity for the epidemiological study of eczema.
