PURPOSE OF REVIEW: Diaper dermatitis is the most common cutaneous diagnosis in infants. In this review, common causes of diaper dermatitis and similarly presenting conditions will be covered, as well as updates on treatments of common diaper dermatitides. RECENT FINDINGS: There have been recent advancements in the treatment of diaper dermatitis. In addition, there are many newly recognized causes of diaper dermatitis that clinicians should be aware of. SUMMARY: Irritant dermatitis is the most common cause of diaper dermatitis. However, there are multiple other common causes of diaper dermatitis and it is thus imperative that the clinician be aware of cutaneous mimickers of irritant diaper dermatitis as well as their treatments.

Acute cutaneous necrosis is defined as a sudden onset of gangrenous skin changes in the skin, associated with significant morbidity and mortality. The following diseases are included in this discussion: coumadin necrosis, heparin necrosis, brown recluse spider bite, necrotizing fasciitis, vasculitis, pyoderma gangrenosum, calciphylaxis, clotting abnormalities and embolic phenomena. The importance of early diagnosis, early distinction and early drug therapy or drug withdrawal must match the diagnosis for maximal preservation of the skin and underlying tissue.

Primary congenital hypothyroidism (CH) is a common and preventable cause of intellectual disability. The incidence rate of CH has been reported to be increasing in the United States, but the factors behind the observed rate increase are not known. We summarize here the data presented at a workshop on CH, at which factors potentially related to the CH-incidence-rate increase (namely, race, ethnicity, sex, and birth outcomes) were evaluated. Data sources for the analyses included a national data set of newborn-screening results and state-specific data from newborn-screening programs in California, Massachusetts, New York, and Texas. The incidence rate of CH increased in the United States by 3% per year; however, an increase did not occur in all states, at a constant rate, or even at the same rate. Analysis of US data (1991-2000) showed a CH-incidence-rate increase only among white newborns. More recently, in California (2000-2007), the rate was constant in non-Hispanic newborns, but it increased among Hispanic newborns. In the national data, the CH-incidence rate increased similarly among boys and girls, whereas in Texas (1992-2006), the rate among boys increased significantly more than among girls and varied according to race and ethnicity. In Massachusetts (1995-2007), low birth weight newborns or newborns who had a delayed rise in thyrotropin concentration accounted for the majority of the recent rate increase. Race, ethnicity, sex, and pregnancy outcomes have affected the observed increasing incidence rate of CH, although there have been some inconsistencies and regional differences. The association with preterm birth or low birth weight could reflect the misclassification of some cases of transient hypothyroxinemia as true CH. Future studies of risk factors should focus on correct initial identification and reporting of demographic characteristics and pregnancy outcomes for cases of CH. In addition, long-term follow-up data of presumed cases of CH should be ascertained to differentiate true cases of CH from cases of transient hypothyroidism.
