Carriers of duplications of chromosome 21 cannot
produce normal children because their gametes are either
nullisomic or disomic; the risk of abortion or an infant with
Down syndrome is 100%.

| Quote: |
| a patient with spinal pop cast presents with bilious vomiting |
most probable cause is duodenal obstruction
this is actually a case of Wilkie's disease or arteriomesentric compression.
also known as cast syndrome
occurs in patients immobilized in a whole body cast(as in spinal cast)
and also in acute loss of fat. 
the third part of duodenum gets compressed between the vertebral column and superior mesentric vessels. 8)
pt presents with features of GOO(gastric outlet obstruction) with bilious vomiting. 8)
treatment of choice is duodenojejunostomy.

aching heart!

| atheroma resulting in angina has the following characters except |
the ans is thick fibrous cap
any atheroma,which has to cause a pain in an heart, has to be vulnerable enuf to break up n attract platelets n other stuff to grow on it,n dat too fast,so dat the heart doesnt gets enuf time to develop contacts(collaterals),and it aches!!!! 
a thick fibrous cap wud only make the atheroma strong headed,n thus less vulnerable to break,n it continues to grow,though very slowly,so dat even if the critical limit of lumen obstruction is crossed,the heart wud have developed enuf collaterals,by then!so dat it is unlikely for this to cause pain! 8)
hope im clear n correct!

The artery of wilkie is the supraduodenal artery which arises from the gastroduodenal artery in the majority of cases and less commonly from the common hepatic artery, supplies both the anterior and posterior surfaces of the first part of the duodenum.

Correct me if I'm wrong, but this appears to be a case of balanced translocation, not duplication, so the chance of a down$ baby will be nil
