The inpatient burden and comorbidities of pyoderma gangrenosum in adults in the United States.
The objective of this study was to determine the prevalence, predictors, outcomes, and costs of hospitalization for pyoderma gangrenosum (PG) in United States adults. Data from the 2002-2012 National Inpatient Sample were analyzed. Findings showed that PG admissions were more likely at teaching and medium or large hospitals. The majority of inpatients with PG were classified with minor or moderate likelihood of dying, but moderate and major loss of function. PG was associated with numerous other health disorders. This study demonstrated a substantial and increasing inpatient burden of PG in the United States, with considerable disability and mortality risk, multiple comorbid health disorders, and costs.

The mental health burden in acne vulgaris and rosacea: an analysis of the US National Inpatient Sample.
Little is known about the mental health (MH) hospitalization among patients with acne and rosacea. The purpose of this study was to determine the MH disorders and cost burden associated with acne and rosacea. The investigators concluded that inpatients with acne or rosacea had increased odds of comorbid MH disorders. In particular, there was an increased number of hospital admissions secondary to a primary MH disorder with coexistent acne/rosacea. MH comorbidities were associated with considerable excess costs among inpatients with acne or rosacea.

Association between climate, pollution and hospitalization for pemphigus in the USA.
The goal of this study was to determine whether the impact of ultraviolet exposure, climate factors and pollutants are associated with pemphigus exacerbation resulting in hospitalization. Data from the National Inpatient Sample was used. The findings indicate a significant statewide variation in the prevalence of hospitalization for pemphigus, with ‘hotspots’ in the southwest and northeast states. Higher rates of admission for pemphigus occurred during the summer and autumn months. All associations remained significant in multilevel regression models that controlled for age, sex and race/ethnicity, except for ultraviolet index, which was associated with pemphigus hospitalization only for Hispanic patients. The authors conclude that higher temperature, UV exposure. and small particle air pollution are associated with increased hospitalization for pemphigus, and that patients with pemphigus may benefit from avoidance of these potential environmental triggers.

Association of vitiligo with hospitalization for mental health disorders in US adults.
The goal of this study was to examine the relationship between vitiligo and mental-health hospitalizations in the US using data from the National Inpatient Sample. Prevalence of hospitalization for mental-health disorders, length of stay (LOS), and cost of care were examined for patients with vitiligo in comparison with those without vitiligo. Hospitalization for mental-health disorders occurred more commonly in those with vitiligo. Vitiligo patients who were hospitalized with any mental-health disorder had higher LOS as well as cost of inpatient care.

Atopic dermatitis and hospitalization for mental health disorders in the United States.
Investigators analyzed data from the Nationwide Inpatient Sample (NIS) from 2002 to 2012 to determine the incidence of mental health (MH) emergencies with atopic dermatitis (AD). Primary admission for MH disorders associated with AD is known for adults with mood disorders, schizophrenia and developmental disorders.

Inpatient burden of juvenile dermatomyositis among children in the United States.
The purpose of this study was to determine the prevalence and risk factors for hospitalization with juvenile dermatomyositis and assess inpatient burden of juvenile dermatomyositis (JDM). The study authors found that JDM contributes to both increased length of hospitalization and inpatient cost of care. Non-Medicaid government insurance was associated with higher rates of hospitalization for JDM while Hispanic and other non-white racial/ethnic groups demonstrated increased length of stay and cost of care.

Epidemiology of eczema herpeticum in hospitalized U.S. children: analysis of a nationwide cohort.
This study used data from the Nationwide Inpatient Sample 2002-2012 to determine incidence, risk factors, comorbidities, costs, length of stay, and mortality in hospitalized children with Eczema herpeticum (EH). A higher risk was associated with younger age and non-white ethnicity (Asian in particular). However there was less frequency of hospitalization associated with lower income quartiles. The mortality incidence was 0.1%.

Cardiovascular comorbidities of pediatric psoriasis among hospitalized children in the United States.
This study sought to determine if there is an association between pediatric psoriasis and cardiovascular comorbidities. It found that in multivariate survey logistic regression models adjusting for age, sex, and race/ethnicity, pediatric psoriasis was significantly associated with 5 of 10 cardiovascular comorbidities.

Predictors of hospitalization, length of stay and costs of care among adults with dermatomyositis in the United States.
The researchers sought to determine the prevalence and risk factors for hospitalization with dermatomyositis and to assess inpatient burden of dermatomyositis. They concluded that there is a significant and increasing inpatient burden for dermatomyositis in the US. Also, there appear to be racial differences as non-whites have higher prevalence of admission, increased length of stay and cost of care.

Inpatient financial burden of atopic dermatitis in the United States.
Little is known about the inpatient burden of atopic dermatitis (AD). The researchers sought to determine some risk factors and financial-burden of hospitalizations for AD in the US. They found that the high prevalence of hospitalization resulted in total inpatient costs of $8,288,083 per-year for adults and $3,333,868 per-year for children. In conclusion, there is a substantial inpatient financial-burden of AD in the US.
