In some cases, survival past birth may be extended if there is mixoploidy with both a diploid and a triploid cell population present. There has been one report of a child surviving to the age of seven months with complete triploidy syndrome. He failed to exhibit normal mental or physical neonatal development, and died from a Pneumocystis carinii infection, which indicates a weak immune system.Triploidy may be the result of either digyny (the extra haploid set is from the mother) or diandry (the extra haploid set is from the father). Diandry is mostly caused by reduplication of the paternal haploid set from a single sperm, but may also be the consequence of dispermic (two sperm) fertilization of the egg. Digyny is most commonly caused by either failure of one meiotic division during oogenesis leading to a diploid oocyte or failure to extrude one polar body from the oocyte. Diandry appears to predominate among early miscarriages, while digyny predominates among triploid zygotes that survive into the fetal period. However, among early miscarriages, digyny is also more common in those cases less than 8+1⁄2 weeks gestational age or those in which an embryo is present. There are also two distinct phenotypes in triploid placentas and fetuses that are dependent on the origin of the extra haploid set. In digyny, there is typically an asymmetric poorly grown fetus, with marked adrenal hypoplasia and a very small placenta. In diandry, a partial hydatidiform mole develops.
Over the years, government agencies and community professional groups, worldwide, have specified elder abuse as a social problem. In 2006, the International Network for Prevention of Elder Abuse (INPEA) designated June 15 as World Elder Abuse Awareness Day (WEAAD), and an increasing number of events are held across the globe on this day to raise awareness of elder abuse and highlight ways to challenge such abuse. Types
Although there are common themes of elder abuse across nations, there are also unique manifestations based upon history, culture, economic strength, and societal perceptions of older people within nations themselves. The fundamental common denominator is the use of power and control by one individual to affect the well-being and status of another older individual. There are several types of abuse of older people that are generally recognized as being elder abuse, including:
Physical: e.g. hitting, punching, slapping, burning, pushing, kicking, restraining, false imprisonment/confinement, or giving excessive or improper medication as well as withholding treatment and medication. Psychological/Emotional: e.g. humiliating a person. A common theme is a perpetrator who identifies something that matters to an older person and then uses it to coerce an older person into a particular action. It may take verbal forms such as yelling,  name-calling, ridiculing, constantly criticizing, accusations, blaming, or nonverbal forms such as ignoring, silence, shunning or withdrawing affection. Elder financial abuse: also known as financial exploitation, involving misappropriation of financial resources by family members, caregivers, or strangers, or the use of financial means to control the person or facilitate other types of abuse.
