Varicella zoster virus primary infection (chickenpox), the virus goes dormant in the nerves, including the cranial nerve ganglia, dorsal root ganglia, and autonomic ganglia. Many years after the person has recovered from chickenpox, VZV can reactivate to cause neurologic conditions. Primary varicella zoster virus infection results in chickenpox (varicella), which may result in complications including encephalitis, pneumonia (either direct viral pneumonia or secondary bacterial pneumonia), or bronchitis (either viral bronchitis or secondary bacterial bronchitis). Even when clinical symptoms of chickenpox have resolved, VZV remains dormant in the nervous system of the infected person (virus latency), in the trigeminal and dorsal root ganglia. VZV
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,
