Frustration or over-gratification was said to result in an oral fixation and in an oral type of character, characterized by feeling dependent on others for nurturance and by behaviours representative of the oral stage. Later psychoanalytic theories shifted the focus from a drive-based approach of dependency to the recognition of the importance of early relationships and establishing separation from these early caregivers, in which the exchanges between the caregiver and the child become internalized, and the nature of these interactions becomes part of the concepts of the self and of others.

Support for this and a variety of other approaches to treat or prevent acral erythema comes from small clinical studies, although none has been proven in a randomised controlled clinical trial of sufficient size.Modifying some daily activities to reduce friction and heat exposure to your hands and feet for a period of time following treatment (approximately one week after IV medication, much as possible during the time you are taking oral (by mouth) medication such as capecitabine). Avoid long exposure of hands and feet to hot water such as washing dishes, long showers, or tub baths. Short showers in tepid water will reduce exposure of the soles of your feet to the drug. Dishwashing gloves should not be worn, as the rubber will hold heat against your palms. Avoid increased pressure on the soles of the feet or palms of hands. No jogging, aerobics, power walking, jumping - avoid long days of walking. You should also avoid using garden tools, household tools such as screwdrivers, and other tasks where you are squeezing your hand on a hard surface. Using knives to chop food may also cause excessive pressure and friction on your palms. Treatment
The main treatment for acral erythema is discontinuation of the offending drug, and symptomatic treatment to provide analgesia, lessen edema, and prevent superinfection. However, the treatment for the underlying cancer of the patient must not be neglected. Often, the discontinued drug can be substituted with another cancer drug or cancer treatment.Symptomatic treatment can include wound care, elevation, and pain medication.
