Very frequent
Posteriorly rotated ears A type of abnormal location of the ears in which the position of the ears is characterized by posterior rotation (the superior part of the ears is rotated towards the back of the head, and the inferior part of the ears towards the front).
 
Synonyms:Ear, posterior angulation, increased; Ears rotated toward back of head; Posteriorly angulated ears; Posteriorly rotated; Posteriorly rotated auricles; Posteriorly-angulated ears; Posteriorly-rotated ears

Seizure A seizure is an intermittent abnormality of nervous system physiology characterized by a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain.
 
Synonyms:Epileptic seizure; Seizures

Severe intrauterine growth retardation Intrauterine growth retardation that is 4 or more standard deviations below average, corrected for sex and gestational age.
 
Synonyms:Intrauterine growth retardation, severe; Severe prenatal growth deficiency
Very frequent
Short foot A measured foot length that is more than 2 SD below the mean for a newborn of 27 - 41 weeks gestation, or foot that is less than the 3rd centile for individuals from birth to 16 years of age (objective). Alternatively, a foot that appears disproportionately short (subjective).
 
Synonyms:Hypoplastic feet; Short feet; Short foot; Small feet
Very frequent
Short stature A height below that which is expected according to age and sex norms. Although there is no universally accepted definition of short stature, many refer to 'short stature' as height more than 2 standard deviations below the mean for age and sex (or below the 3rd percentile for age and sex dependent norms).
 
Synonyms:Decreased body height; Height less than 3rd percentile; Short stature; Small stature; Stature below 3rd percentile
