Chickenpox Chickenpox Chickenpox, also known as varicella, is a highly contagious disease caused by the initial infection with varicella zoster virus (VZV). The disease results in a characteristic skin rash that forms small, itchy blisters, which eventually scab over. It usually starts on the chest, back, and face then spreads to the rest of the body. Other symptoms may include fever, tiredness, and headaches. Symptoms usually last five to seven days. Complications may occasionally include pneumonia, inflammation of the brain, and bacterial skin infections. The disease is often more severe in adults than in children. Symptoms begin 10 to 21 days
Placental disease Placental disease Ischemic placental disease leads to the attachment of the placenta to the uterine wall to become under-perfused, causing uteroplacental ischemia. Where the term overarches the pathology associated with preeclampsia, placental abruptions and intrauterine growth restriction (IUGR). These factors are known to be the primary pathophysiology cause placental disease. Which is considered to be associated with more than half of premature births. Abnormalities present within the spiral arteries lead to higher velocities in blood, in turn causes the maternal villi to shred. Which trigger pro-coagulator molecules to be released into the blood stream causing action of the coagulator cascade,
