Fetal warfarin syndrome is a disorder of the embryo which occurs in a child whose mother took the medication warfarin (brand name: Coumadin) during pregnancy.Resulting abnormalities include low birth weight, slower growth, intellectual disability, deafness, small head size, and malformed bones, cartilage, and joints.
Bone tissue is a dynamic system with active metabolism. [24] Bone tissue remodelling or bone remodeling is a successive chain of old bone matrix removal and its replacement with a new one. [25] These processes make a child’s skeleton grow and extend, while childhood is characterized by bone tissue growth rather than its resorption.
Pregnancy- and lactation-associated osteoporosis (PLO; also known as pregnancy-related osteoporosis) is a rare early presentation of osteoporosis in which young women experience low trauma or spontaneous fractures during or soon after pregnancy or lactation. [citation needed]
Progesterone causes many changes to the genitourinary system. A pregnant woman may experience an increase in the size of the kidneys and ureter due to the increase blood volume and vasculature. Later in pregnancy, the woman might develop physiological hydronephrosis and hydroureter, which are normal. [33]
The case referred by Abulcasis. The patient was pregnant in two separate occasions but never gave birth. "A long time" after, she developed a large swelling in the navel area, that turned into a suppurating wound and would not heal despite receiving treatment. This continued until Abulcasis removed several fetal bones through the wound, which ...
A new study, published April 8 in The Proceedings of National Academy of Sciences found that pregnancy can accelerate aging in young women. Researchers from the Columbia University Mailman School ...
Endochondral ossification is responsible for development of most bones including long and short bones, [4] the bones of the axial (ribs and vertebrae) and the appendicular skeleton (e.g. upper and lower limbs), [5] the bones of the skull base (including the ethmoid and sphenoid bones) [6] and the medial end of the clavicle.

PTHrP acts similarly to parathyroid hormone in that it binds to the parathyroid hormone 1 receptors on the kidneys and bones and causes an increased tubular reabsorption of calcium and activation of osteoclast activity, respectively. [22] Osteoclasts are a type of bone cell which cause bone resorption, releasing calcium into the bloodstream.
