Why do newborns get pustules?
Herpes simplex (HSV) infection is one of the most feared causes of blisters and pustules in the newborn. Subtle or inconspicuous skin lesions may herald the onset of infection, and the failure to promptly recognize and treat neonatal HSV infection can worsen the prognosis of this potentially devastating disease. Skin lesions are present in both intrauterine and neonatal herpes simplex infection, and although there is considerable overlap, the time of onset and many of the clinical features of the skin disease differ.
Why do babies get blisters?
The causes of blisters and pustules in newborns and young infants are influenced by the clinical setting, including geography and whether patients are seen in a hospital or clinic. Infection is the most common etiology in developing countries. In a study of neonates in India with blisters and pustules, bacterial infection was the most common overall, whereas erythema toxicum was the most prevalent non-infectious etiology. In a prospective study of newborn inpatients in California examined by pediatric dermatologists, the most common eruption in newborns was erythema toxicum. In a retrospective European study done in a Level 3 nursery, vesicles and pustules were the sole reason for admission to the Neonatal Intensive Care Unit (NICU) in 29.8% of infants admitted because of skin lesions.
How long does it take for a HSV infection to develop?
In intrauterine HSV infection , skin lesions are usually present at the time of birth, or develop within 24–48 h in 90% of affected infants. In addition to the characteristic vesicular eruption, widespread bullae and erosions resembling epidermolysis bullosa, absence of skin on the scalp (resembling aplasia cutis congenita), polycyclic plaques with erosions, scars on the scalp, face, trunk, or extremities, and absence of nail plates have been reported. Affected infants are often premature, weighing less than 2500 g, and most have other manifestations of TORCH infections e.g. microcephaly and chorioretinitis. Some have limb and bone abnormalities.
What is the name of the infection that causes crusted erosions in infants?
Papules, pustules, and crusted erosions in a 9-month-old infant with S. aureus infection.
What is scalded skin syndrome?
Staphylococcal scalded skin syndrome (SSSS) is an acute, potentially life-threatening disease caused by exotoxin-producing S. aureus , usually phage types 1, 2, or 3. Although epidemics as well as sporadic outbreaks of SSSS have been reported, including in newborn nurseries, it is still an uncommon to rare condition. A population-based study in Germany found an incidence of approximately 0.1 cases per million inhabitants per year (including all ages) with a bimodal distribution of ages: young children and older adults. In a group of neonates and infants with erythroderma, SSSS was the etiology of their skin findings in only 7%. Only a few cases of congenital SSSS have been reported; the vast majority of infants present between 3 and 7 days of age or older, with an abrupt onset of cutaneous erythema, tenderness, and widespread areas of skin fragility, superficial blistering, and/or erosions. Erythema often begins on the face, especially around the mouth. In newborns, flaccid blisters usually appear within 24–48 h and quickly erode, producing areas of superficially denuded skin. These erosions are particularly prominent in areas of mechanical stress, such as the shoulders, buttocks, body folds, feet, and hands. When firmly rubbed, the skin is easily separated from the underlying epidermis (Nikolsky’s sign). A milder, but more common form of SSSS, characterized by erythema, tiny erosions or pustules, with or without a scarlatiniform rash is often seen in older infants and children. Periorificial accentuation with scale or crusting is a common feature of both forms ( Fig. 10.4 ).
Is vesiculopustular bullous a life threatening condition?
Vesiculopustular and bullous disorders are common in the neonatal period and the first years of life. Accurate and prompt diagnosis is essential because some conditions that present with blisters and pustules are truly life-threatening. In contrast, many others are innocuous and self-limited; misdiagnosis of a more serious condition can lead to iatrogenic complications, unnecessary expense, and parental anguish.
Is S. aureus common in newborns?
Skin infections caused by S. aureus are relatively common in newborns and infants. Epidemic outbreaks are occasionally seen in newborn and intensive care nurseries. In recent years, methicillin-resistant S. aureus (MRSA) infections have been increasingly reported in hospital nursery and maternity units, paralleling a trend toward such infections in other settings. Interestingly, most have had the molecular fingerprint of community-acquired (CA-MRSA), rather than nosocomial MRSA. Two forms of S. aureus infection involving the skin can occur: direct skin infection and staphylococcal scalded skin syndrome, caused by staphylococcal toxins.
As nouns the difference between blister and vesicle

Why do vesicles swell?
Vesicles are often easy to recognize. Most develop on the surface of the skin and cause it to swell with fluid. The skin around a vesicle keeps the fluid contained. Vesicles tend to rupture easily and release their fluid onto the skin. When the fluid dries, it may turn yellow or crusty.
