Abstract
Neonatal period is the first 28 day of life or 44weeks postcocepteual age. Neonate’s infant classified according to gestational age into fullterm who born between 37 and 42 weeks of estimated gestational age, Premature who born before 37th weeks of gestation and postmature who is born after 42 weeks of gestation Another widely accepted classification according to birth weight which positively proptionate with gestational age apropriat for gestational age (AGA) babies who born with birth weight between the 10th and 90th percentiles of normal for its population group, small for gestational age (SGA) babies born with birth weight below 10th percentile of normal for its population group and large for gestational age (LGA) who born with birth weight above 90th percentile of normal for its population group
In general a newborn weighing below 2500g at birth regardless to his gestational age is low birth weight (LBW), if birth weight below 1500g is very low birth weight (VLBW) and extremely low birth weight if below 1000g
The skin is the most visible and easily accessible organ of the body. It serves many purposes, acting as a barrier against infection, protecting internal organs, contributing to thermoregulation, storing insulating fats, excreting electrolytes and providing tactile sensory input (Shwayder and Akland, 2005). Neonatal skin plays an important role with vernix caseosa through their antimicrobial properties to protect the neonate in utero and after birth Skin disorders are commonly seen during the neonatal period and they may be benign transient lesions, napkin dermatitis and related disorders, lesions of infections, blistering dermatoses, genodermatoses, or birth marks
Benign transient cutaneous lesions include; transient vascular phenomena and transient pustular or papulopustular dermatosis which are common skin findings in neonates. Napkin dermatitis is commonly seen in neonates and it should be differentiated from other disorders that may involve the napkin area like psoriasis or seborrheic dermatitis.
