Superficial burns cause pain lasting two or three days, followed by peeling of the skin over the next few days. Individuals with more severe burns may indicate discomfort or complain of feeling pressure rather than pain. Full-thickness burns may be entirely insensitive to light touch or puncture. While superficial burns are typically red in color, severe burns may be pink, white or black. Burns around the mouth or singed hair inside the nose may indicate that burns to the airways have occurred, but these findings are not definitive. More worrisome signs include: shortness of breath, hoarseness, and stridor or wheezing. Itchiness is common during the healing process, occurring in up to 90% of adults and nearly all children. Numbness or tingling may persist for a prolonged period of time after an electrical injury. Burns may also produce emotional and psychological distress. Cause
Burns are caused by a variety of external sources classified as thermal (heat-related), chemical, electrical, and radiation. In the United States, the most common causes of burns are: fire or flame (44%), scalds (33%), hot objects (9%), electricity (4%), and chemicals (3%). Most (69%) burn injuries occur at home or at work (9%), and most are accidental, with 2% due to assault by another, and 1–2% resulting from a suicide attempt. These sources can cause inhalation injury to the airway and/or lungs, occurring in about 6%.Burn injuries occur more commonly among the poor. Smoking and alcoholism are other risk factors. Fire-related burns are generally more common in colder climates.
Similarly, fungus can be seen under a microscope or found on a culture. Some viral infections may cause a rash with boils on a reddish base. Rashes caused by herpes simplex virus and varicella zoster virus in particular may be confused with erythema toxicum neonatorum. These viruses are diagnosed by scraping the base of a lesion. Multinucleated giant cells can be seen under a microscope. Some of these tests may be ordered if the diagnosis is unclear. Treatment
Erythema toxicum neonatorum resolves without treatment, typically within one or two weeks. There are no associated systemic symptoms or long-term consequences of the rash. History
The rash of erythema toxicum neonatorum has been described by doctors for centuries. Ancient Mesopotamians believed that it represented a cleansing mechanism against the mothers blood. Later physicians believed that it was caused by the skins response to meconium. The name erythema toxicum neonatorum was first used by Dr. Karl Leiner in 1912 because he believed that the rash was caused by enterotoxins. Although Leiners hypothesis was incorrect and the rash is not actually caused by toxins, the medical community continues to call the rash erythema toxicum neonatorum. References
