Comorbidities and inpatient mortality for pemphigus in the U.S.A.

The morbidity and mortality associated with pemphigus and its treatments have not been fully described. Previous studies have found conflicting results about certain comorbidities and were limited by small sample sizes.

Hospitalization, inpatient burden and comorbidities associated with bullous pemphigoid in the U.S.A.

Bullous pemphigoid (BP) is associated with significant disability and comorbid health disorders that may lead to or result from hospitalization. However, little is known about the inpatient burden and comorbidities of BP.

Validation of International Classification of Disease Ninth Revision codes for atopic dermatitis

Evaluation of large‐scale data sets is needed to better understand the epidemiology, cost, and burden of atopic dermatitis (AD). We sought to validate the use of ICD‐9‐CM codes for identifying AD.

Severity strata for Eczema Area and Severity Index (EASI), modified EASI, Scoring Atopic Dermatitis (SCORAD), objective SCORAD, Atopic Dermatitis Severity Index and body surface area in adolescents and adults with atopic dermatitis

Scoring systems for assessing the signs of atopic dermatitis (AD) are complex and difficult to interpret. Severity strata are helpful to interpret these assessments properly.

Pediatric Stevens-Johnson syndrome and toxic epidermal necrolysis in the United States

Background: Little is known about the epidemiology of Stevens‐Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) in children. Objective: We sought to determine the morbidity, mortality, and comorbid health conditions of SJS and TEN in US children. Methods: This was a cross‐sectional study of the 2009 to 2012 Nationwide Inpatient Sample, which contains a representative 20% sample of all US hospitalizations. Sociodemographics, inflation‐adjusted cost, length of stay, comorbidities, and mortality were analyzed using descriptive statistics and multivariate regression analyses. Results: The incidences of SJS, SJS‐TEN, and TEN were a mean 5.3, 0.8, and 0.4 cases per million children per year in the US, respectively. Prolonged length of stay and higher costs of care (SJS: 9.4 ± 0.6 days,
