Treprostinil, sold under the brand names Remodulin for infusion, Orenitram for oral, and Tyvaso for inhalation, is a vasodilator that is used for the treatment of  pulmonary arterial hypertension. Treprostinil is a synthetic analog of prostacyclin (PGI2). Treprostinil was approved for use in the United States in May 2002.The drug can be given in various forms: IV, subcutaneous injection, oral inhalation, as well as oral extended-release tablets. The subcutaneous administration tends to be very painful. Medical uses
Treprostinil is indicated for the treatment of pulmonary arterial hypertension in people with NYHA Class II-IV symptoms to diminish symptoms associated with exercise. It may be administered as a continuous subcutaneous infusion or continuous intravenous infusion; however, because of the risks associated with chronic indwelling central venous catheters, including serious blood stream infections, continuous intravenous infusion should be reserved for patients who are intolerant of the subcutaneous route, or in whom these risks are considered warranted. This medication is also available in inhaled and tablet forms. In people with pulmonary arterial hypertension requiring transition from epoprostenol sodium (Flolan), treprostinil is indicated to diminish the rate of clinical deterioration. The risks and benefits of each drug should be carefully considered prior to transition. Treprostinil therapy may be effective in treating Degos disease. Adverse effects
Since treprostinil is a vasodilator, its antihypertensive effect may be compounded by other medications that affect the blood pressure, including calcium channel blockers, diuretics, and other vasodilating agents.

Collecting stem cells
It is currently possible to collect two types of stem cells during childbirth: amniotic stem cells and umbilical cord blood stem cells. They are being studied as possible treatments of a number of conditions. Placentophagy
Some animal mothers are known to eat their afterbirth, called placentophagy. In some cultures the placenta may be consumed as a nutritional boost, but it may also be seen as a special part of birth and eaten by the newborns family ceremonially. In the developed world the placenta may be eaten believing that it reduces postpartum bleeding, increases milk supply, provides micronutrients such as iron, and improves mood and boosts energy. The CDC advises against this practice, saying it has not been shown to promote health but has been shown to possibly transmit disease organisms that were passed from the placenta into the mothers breastmilk and then infecting the baby.
