Q

Q

Q

Describe the pathophysiology of rhesus disease.

A
  1. Foetal Rh+ RBC’s leak through the placenta and interact with the mother’s blood -> IgM reaction -> sensitisation.
  2. IgM can’t cross the placenta and so there is no RBC lysis but memory B cells are created.
  3. On a subsequent pregnancy, IgG may cross the placenta and cause foetal RBC lysis.

Q

Describe the physiology behind quiescence?

Q

Q

Induction of labour: describe the theory that suggests that there are signals from the baby.

A

Increased ACTH or increased foetal surfactant proteins activate amniotic fluid macrophages. These migrate to the uterine wall, there is up-regulation of inflammatory gene expression which stimulates labour.

What is a molar pregnancy?

A

A molar pregnancy is a type of GTD. It occurs when there is an abnormality in chromosomal number during fertilisation. A non-viable fertilised egg implants and fails to come to term. It grows into a mass in the uterus.

Q

What is gestational trophoblastic disease (GTD)?

A

GTD describes a group of pregnancy related tumours. These tumours can be pre-malignant and often benign e.g. molar pregnancies or malignant e.g. choriocarcinoma and invasive mole.

Q

Describe the physiology of micturition.

A

The bladder fills and stretch receptors are stimulated. Afferent impulses stimulate the parasympathetic action of detrusor muscle; it contracts. The urethral sphincters relax; this is mediated by inhibition of the neurones to them. The PAG is stimulated.
