Essential hypertension (also called primary hypertension, or idiopathic hypertension) is a form of hypertension without an identifiable physiologic cause. [ 1][ 2] It is the most common type affecting 85% of those with high blood pressure. [ 3][ 4] The remaining 15% is accounted for by various causes of secondary hypertension. [ 3]
Fetal-maternal haemorrhage is the loss of fetal blood cells into the maternal circulation. It takes place in normal pregnancies as well as when there are obstetric or trauma related complications to pregnancy. Normally the maternal circulation and the fetal circulation are kept from direct contact with each other, with gas and nutrient exchange ...
The diagnostic criteria for chronic hypertension are typically considered to be at least two separate blood pressure readings taken at least four hours apart with systolic blood pressure ≥ 140mmHg, diastolic blood pressure ≥90 mmHg, or both, identified before pregnancy, before 20 weeks gestation, or persisting at least 12 weeks after giving ...
Hypertension occurs in approximately 8–10% of pregnancies. [25] Two blood pressure measurements six hours apart of greater than 140/90 mmHg are diagnostic of hypertension in pregnancy. [32] High blood pressure in pregnancy can be classified as pre-existing hypertension, gestational hypertension, or pre-eclampsia. [33]
The most important clinical complication of scleroderma involving the kidney is scleroderma renal crisis (SRC), the symptoms of which are malignant hypertension (high blood pressure with evidence of acute organ damage), hyperreninemia (high renin levels), azotemia (kidney failure with accumulation of waste products in the blood), and ...

Prolactinoma. A prolactinoma is a tumor ( adenoma) of the pituitary gland that produces the hormone prolactin. It is the most common type of functioning pituitary tumor. [ 1] Symptoms of prolactinoma are due to abnormally high levels of prolactin in the blood ( hyperprolactinemia ), or due to pressure of the tumor on surrounding brain tissue ...
Fetal distress, also known as non-reassuring fetal status, is a condition during pregnancy or labor in which the fetus shows signs of inadequate oxygenation. [ 1] Due to its imprecision, the term "fetal distress" has fallen out of use in American obstetrics. [ 2][ 1][ 3] The term "non-reassuring fetal status" has largely replaced it. [ 4]
