The Merck Manual defines physical abuse involves the physical battery of a child. Emotional abuse involves the emotional or mental battery of a child, which often damages the child's emotional growth and self-esteem. Sexual abuse or molestation includes exposure, genital manipulation, sodomy, fellatio, and coitus. Vaginal penetration by an unrelated person constitutes rape. Often, the adult is a close family friend. If the adult is biologically related, the offense is termed incest. When young children are involved, the offense most often is nonviolent and repetitive and may be concealed within the family. Neglect includes failure to meet a child's basic physical and medical needs, emotional deprivation, and desertion.
Abuse: Generally, abuse is caused by the breakdown of impulse control in the parent or guardian. Four contributing factors are recognized:
Parental personality features: The childhood experience of the parent may have lacked affection and warmth, often included abuse, and was not conducive to the development of adequate self-esteem or emotional maturity. Lacking an early loving environment, abusive parents may look toward their children as a source of the affection and support they never received. As a result, they may have unrealistic expectations of what their child can supply for them; they are frustrated easily and lose control, unable to give what they never experienced. Drug or alcohol use may provoke impulsive and uncontrolled behaviors toward the child. Less commonly, a parent may be frankly psychotic.
A "difficult" child: Irritable, demanding, or hyperactive children may provoke parents' tempers, as may a handicapped child, who often is more dependent for care. Premature or sick infants separated from parents early in infancy and biologically unrelated children (eg, stepchildren) may not form strong emotional ties with their parents or guardians. Even in the absence of these conditions, parents may have unrealistic expectations of what a child's performance should be and may punish him severely with little justification.
Inadequate support: Parents may feel isolated, unprotected, and vulnerable without the physical and psychologic support of relatives, friends, neighbors, or peers, particularly in times of stress.
A crisis: Situational stress may precipitate abuse, particularly when support is unavailable.
Neglect: Often, neglect is seen among families with physical, psychologic, or substance abuse problems. Acute or chronic depression, especially maternal, is often present; chronic medical problems of a parent may also contribute. Drug or alcohol abuse by one or both parents frequently results in chronic impoverishment and a distortion of priorities in family life. Desertion by the father, himself inadequate, unable or unwilling to assert a controlling influence in the family, may precipitate neglect. Children of cocaine-using mothers are particularly at risk for desertion.
Manifestations of Abuse
History: Features suggestive of abuse are (1) parental reluctance to give a history of injury; (2) a history that may be inconsistent with the apparent stage of resolution of the injury and may vary depending on the information source; (3) a history of injury that is incompatible with the child's developmental capability; (4) an inappropriate response by the parents to the severity of the injury; and (5) delay in reporting the injury.
Physical: Common signs are skin lesions, such as ecchymoses, hematomas, burns, welts, and abrasions in various stages of development (eg, cigarette burns, arcuate bruises from extension cord whipping, symmetric scald burns of upper or lower extremities); serious traumatic injury to the mouth, eye, abdominal organs, and CNS, which may produce permanent damage; and fractures. Fractures may be single or multiple, and a skeletal survey may show bony injuries in various stages of resolution. Metaphyseal fractures and subperiosteal elevations in long bones occur in infants. Major diagnostic considerations in the examination are (1) multiple injuries at different stages of resolution or development; (2) cutaneous lesions specific for particular sources of injury; and (3) repeated injury, which is suggestive of abuse or inadequate supervision.
Physical signs of sexual abuse may include difficulty in walking or sitting, genital trauma, vaginal discharge or pruritus, recurrent UTIs, or a sexually transmitted infection. However, there may be no physical indications of injury. Sexually transmitted disease of any sort in any child < 12 or 13 yr must be viewed as the result of sexual molestation until ruled out.
Emotional: Emotional manifestations of abuse are less easily defined than are physical signs. In infants, failure to thrive is a common early observation. Delayed development of social and language skills often results from inadequate parental stimulation and interaction. Small children may be distrustful, superficial in interpersonal relationships, passive, and overly concerned with pleasing adults. The emotional impact on children usually becomes obvious at school age, when difficulties develop in forming relationships with teachers and peers. Often, emotional effects can be documented only after the child has been placed in another environment, at which time aberrant behaviors abate.
When a child has been sexually abused, his behavior (eg, irritability, fearfulness, insomnia) may be the only clue for diagnosis. Careful interviewing of the child by a trained professional may be the only means of adding necessary details. Older children may be threatened with physical injury by the offender if they tell and, thus, may conceal repeated assaults.
Manifestations of Neglect
Malnutrition, fatigue, and lack of hygiene or appropriate clothing are common due to inadequate provision of food, clothing, or shelter, despite available supportive community resources. Desertion or death by starvation is seen in extreme cases. As many as 1/2 of infantile failure-to-thrive cases may be due to neglect.
In early infancy, retardation of emotional growth may occur with blunting of affect and lack of interest in the environment. This commonly accompanies failure to thrive and is often misdiagnosed as mental retardation or physical illness. Signs of emotional deprivation in older children include poor attendance and performance at school and bad relationships with peers and adults.
Failure to seek preventive medical or dental attention, such as immunizations and routine health supervision, and delay in seeking care for illness may be clues to inadequate family functioning.
