Severe local pain (unilateral prominence)
Marked deterioration after initial milder form of illness (double sickening)
What test results would you expect in a Hydatidiform mole (molar pregnancy)?
High bHCG
Low TSH
High thyroxine
The biochemical structure of beta hCG is very similar to that of luteinizing hormone (LH), follicle-stimulating hormone (FSH), and thyroid-stimulating hormone (TSH).
can result in signs and symptoms of thyrotoxicosis. High levels of T4 and T3 have a negative feedback effect on the pituitary gland to stop secretion of TSH, causing and overall reduction in TSH levels.

(C)aput (S)uccedaneum = (C)rosses (S)uture lines
Caput succedaneum is a subcutaneous, extraperiosteal, collection of fluid that collects as the result of pressure on the baby’s head during delivery.
