Background/objectives: Erythema toxicum neonatorum (ETN) and transient neonatal pustular melanosis (TNPM) are benign pustular skin conditions that are relatively common in newborns, but the predisposing factors for these conditions are unknown. Our goal was to verify the prevalence of ETN and TNPM and their predisposing factors in a large sample of neonates.

Methods: In this prospective 1-year multicenter study, 2,831 neonates (age ≤72 hours) born in southern Brazil were randomized to undergo skin examination by a dermatologist. Read More

Introduction: neonatal and infantile skin diseases are frequently encountered in the clinical practice and represent worldwide a socioeconomic issue. They encompass a wide range of acquired or congenital conditions, including infections, vascular lesions and inflammatory diseases and can present with different degrees of severity, leading in some cases to dramatic complications. Areas covered: In this paper we report the most recent evidences on the management of some common skin diseases in neonates and infants. Read More

Skin findings during the initial month of life are ubiquitous. One study estimated that more than 95% of newborns have cutaneous findings, which often are distressing to parents but frequently are benign and self-limited. Among them are milia, cutis marmorata, congenital dermal melanocytosis, and the benign neonatal pustular eruptions (eg, benign cephalic pustulosis, erythema toxicum neonatorum, transient neonatal pustular melanosis).

The neonatal period comprises the first four weeks of life. It is a period of adaptation where the skin often presents several changes: transient lesions, resulting from a physiological response, others as a consequence of transient diseases and some as markers of severe disorders. The presence of pustules in the skin of the newborn is always a reason for the family and for the assisting doctor to be worried, since the newborn is especially vulnerable to bacterial, viral or fungal infection.

Neonatal pustular eruption is a group of disorders characterized by various forms of pustulosis seen in first 4 weeks of life. Its presentation is often similar with some subtle differences, which can be further established by few simple laboratory aids, to arrive at a definite diagnosis. Given their ubiquitous presentation, it is sometimes difficult to differentiate among self-limiting, noninfectious, pustular dermatosis such as erythema toxicum neonatorum, transient neonatal pustular melanosis, miliaria pustulosa, etc. Read More

Background: The spectrum of dermatological manifestations during neonatal period varies from transient self-limiting conditions to serious dermatoses; the latter, fortunately few, are disproportionately stressful to the parents, who due to lack of specialized pediatric dermatology clinics frequently get tossed between a dermatologist and a pediatrician.

Objectives: This study was formulated to record cutaneous changes over the first five postnatal days of life and to statistically correlate those changes occurring in ≥ 11 neonates with three (parity, associated illnesses, and mode of delivery) maternal and three (sex, birth weight, and gestational age) neonatal factors.

Methods: This descriptive, cross-sectional study at a tertiary care hospital entailed recording detailed dermatological examination of 300 neonates having some (physiological and/or pathological) cutaneous changes and their statistical evaluation using the Chi-square test and significance (P < 0.

Erythema Toxicum, a rash frequently present in the healthy newborn infant is an innate, immune response to the first commensal micro flora. Flushing and urtication are seen in this manifestation suggesting mast cell (MC) activation and MC derived mediator release. It has recently become evident that MCs participate in the protective, innate immune response against microbes also by secreting products toxic to pathogens such as cathelicidin peptide antibiotics.

Histologically, the rash is characterized by an upregulation of proinflammatory activity and a local recruitment of immunocytes, including macrophages. High mobility group box chromosomal protein 1, a nuclear and cytosolic protein, is also a pro-inflammatory cytokine released by macrophages in response to microbial stimulation. Read More

Erythema toxicum neonatorum is a common rash of unknown etiology affecting healthy newborn infants. In this study, we postulated that the rash reflects a response to microbial colonization of the skin at birth, and that the hair follicle constitutes an "easily opened door" for microbes into the skin of the newborn. We collected microbial cultures from the skin of 69 healthy, 1-d-old infants with and without erythema toxicum to identify the colonizing flora and correlate culture results with clinical findings.

Erythema toxicum neonatorum is a benign rash of unknown etiology, present to various degrees in most term newborns and characterized by an accumulation of eosinophils in dermal lesions. The recruitment of leukocytes to tissues implicates the involvement of adhesion molecules, cytokines, and chemokines. We therefore performed immunohistochemistry on punch biopsy specimens from cutaneous lesions of ten 1-day-old infants with erythema toxicum using specific monoclonal antibodies directed against a variety of adhesion molecules, cytokines, chemokines, and cell type-specific membrane markers.
