Conjoined Twins In Children
Conjoined twins are identical twins whose bodies are connected to each other, which is a rare phenomenon. Most conjoined twins are stillborn or die shortly after birth. Some surviving conjoined twins can be surgically separated. Conjoined twins develop when a single fertilized egg only partially splits into twin fetuses, or when an egg splits into twins but ...Read more
Good one - no.: Although your question has metaphysical attributes, i would say that clearly cephalopagus conjoined twins are two genetically identical individuals fused at the head, but having separate brain anatomy and psyche. ...Read more
Varies: Depends on the degree and site of joining. It can be as simple as a skin tube with a few vessels in it, to sharing internal organs and fusion of the crest of the skulls. The surgery to separate each in creases in complexity and sometimes would require the sacrifice of one for instance if there were only one brain or one heart. ...Read more
Expect that this: would be managed through a C section. ...Read more
When conjoined twins are separated and survive the surgery do they still have the same average life span as would a baby born un conjoined?
Depends: Often conjoined twins share organs and other structures that are vital for living a normal life. It would depend on how they are conjoined. Generally their life expectancy would be lower and moreso in 1 twin. Please ask your pediatric surgeon for guidance. He/she would be the best to know. All the best with this difficult dilemma. ...Read more
Uncomfortably.: The few historically reported non-separated conjoined twins that survived to adulthood had even fewer instances of marriage and i can only imagine that their intimate relations were not comfortable as they could not have been private. ...Read more
Case reports only.: Most such cases die. The exceptions serve to illustrate this rule and are few and far between. ...Read more
Unless very: superficial connection, both twins are likely to die if not separated. ...Read more
Conjoined twins: The term "Siamese twins" isn't used medically any longer and may be considered a somewhat crude term for conjoined twins who are identical twins who did not fully separate from each other in the very early stages of development during gestation(prior to birth). Identical twins are really natural "clones"-- a single fertilized egg that split early long before birth into two fully separated beings. ...Read more
How indeed?: By bending a lot of rules of society, ethics and even physics, I am sure. ...Read more
They both die.: Unless they can be emergently/urgently separated with the focus on maximizing the survivor's chance of independent living, both conjoined twins die when one dies. ...Read more
I have a fraternal twin brother with microdeletion 22q11.2 (velocardiofacial syndrome). What are the chances my children will have the same disorder?
Minimal: These odd micro-deletion syndromes are thought to arise as new defects which could be dominantly passed. Unless you carry it, you won't pass it to your kids and they would have the same risk as the general population to acquire it (new). You might benefit from discussing any and all genetic risk issues from both sides of the family with a geneticist. ...Read more
Not always: They would be no more likely to look alike than any other siblings. ...Read more
How can I prevent my 3 children from suffering depressive illness like me. Ages twins 10 and 13 yrs.
Why worry?: There is nothing you can do directly to prevent if it is a genetic illness. Life bangs us all around a bit and if we have the genetics of depression, which by the way require more than one gene, then there's a chance that we will develop it and a chance that it could be recurrent or chronic. Trust that as they get older the treatments will be better and perhaps even a cure will be found. ...Read moreSee 1 more doctor answer
Twin girls, one dies complications of histiocytosis x (dod 1985) other twin has had no evidence. Are her children at risk?
Most likely no...: Langerhans cell histiocytosis is usually not inherited and typically occurs in people with no history of the disorder in their family. A few families with multiple cases of langerhans cell histiocytosis have been identified, but the inheritance pattern is unknown. ...Read moreSee 1 more doctor answer
What do you suggest if my husband always like the idea to have twins children. is there really a way to get yourself a twins, or is it just pure luck?
Not natural ways: There are medications that can cause multiple eggs to ovulate. There is also in-vitro fertilization where you place two embryos in. But there are no natural ways to promote twinning - what you hear and read are a bunch of wives tales - otherwise it is indeed just something that happens. Not always a good thing , though. Much higher risk of premature birth and all the accompanying problems. ...Read more
