The World Health Organization (WHO) and the International Society for Prevention of Child Abuse and Neglect (ISPCAN) identify multiple factors at the level of the individual, their relationships, their local community, and their society at large, that combine to influence the occurrence of child maltreatment. At the individual level, studies have shown that age, mental health, and substance use, and a personal history of abuse may serve as risk factors of child abuse. At the level of society, factors contributing to child maltreatment include cultural norms that encourage harsh physical punishment of children, economic inequality, and the lack of social safety nets. WHO and ISPCAN state that understanding the complex interplay of various risk factors is vital for dealing with the problem of child maltreatment.Factors related to relationships include marital strife and tension. Parents who physically abuse their spouses are more likely than others to physically abuse their children. However, it is impossible to know whether marital strife is a cause of child abuse, or if both the marital strife and the abuse are caused by tendencies in the abuser. Parents may also set expectations for their child that are clearly beyond the childs capability (e.g., preschool children who are expected to be totally responsible for self-care or provision of nurturance to parents), and the resulting frustration caused by the childs non-compliance may function as a contributory factor of the occurrence of child abuse. Most acts of physical violence against children are undertaken with the intent to punish.
Problems with blood cell formation result in some combination of low red blood cells, low platelets, and low white blood cells. Some types have an increase in immature blood cells, called blasts, in the bone marrow or blood. Fibrous dysplasia of bone
Fibrous dysplasia of bone is a disorder where normal bone and marrow is replaced with fibrous tissue, resulting in formation of bone that is weak and prone to expansion. As a result, most complications result from fracture, deformity, functional impairment and pain. Macroscopic scale
Hip dysplasia
Hip dysplasia is an abnormality of the hip joint where the socket portion does not fully cover the ball portion, resulting in an increased risk for joint dislocation. Hip dysplasia may occur at birth or develop in early life. Regardless, it does not typically produce symptoms in babies less than a year old. Occasionally one leg may be shorter than the other. The left hip is more often affected than the right. Complications without treatment can include arthritis, limping, and low back pain. Multicystic dysplastic kidney
Multicystic dysplastic kidney (MCDK) is a condition that results from the malformation of the kidney during fetal development. The kidney consists of irregular cysts of varying sizes. Multicystic dysplastic kidney is a common type of renal cystic disease, and it is a cause of an abdominal mass in infants. Etymology
From Ancient Greek δυσ- dys-,  "bad" or "difficult" and πλάσις plasis, "formation". The equivalent surface analysis, in parallel with classical compounds, is dys- + -plasia. See also
