Q

Describe the structure of the breast

A
  • Consists of Secretory Lobules which empty into Ductules
  • Ductules from 15-20 Lobules combine into a duct, which widens at the Ampulla (a small reservoir)
  • Lactiferous Duct carries secretions to the outside

Q

Describe Postnatal/ Baby Blues

When does it peak?

(Managed by support and reassurance)

A
  • Common, considered normal up to 2 weeks after delivery
  • Altered mood due to hormonal changes
  • Mother feels more tearful or anxious
  • Peaks at day 4/5

Q

Describe Post-Partum Depression

(Important to ask about as mothers may be reluctant to share that they’re feeling depressed)

When can pharmacological managements be started?

A
  • Occurs within 4 weeks of delivery, and in 13% of women

- If symptoms last longer than a month

Q

What are 4 symptoms of Puerperal Psychosis?

What are the % risks of suicide and infanticide

A
  • Anxiety
  • Mania
  • Delusions
  • Paranoid thoughts

Suicide risk: 5%
Infanticide risk: 4%

18
Q

Full development of the breast occurs under the influence of what?

A
  • High levels of Estradiol and Progesterone

- Gradual increase in PRL and hPL levels

19
Q

List 4 types of hormones that affect the breast and what they do

A
  • Mammogenic: Promote proliferation of alveolar + duct cells
  • Lactogenic: Promote initiation of milk production
  • Galactokinetic: Promote contraction of myoepithelial cells
  • Gelactopoietic: Maintain milk production
20
Q

PRL is needed for milk production.

How does sucking stimulate PRL release?

A

Normally, Dopamine inhibits PRL release

  • Suckling stimulates neurons from spinal cord to inhibit Dopamine release, thus increasing PRL levels
  • This leads to stimulation of milk production by breasts

Thus, suckling maintains milk production

21
Q

Neurons from the spinal cord stimulate Oxytocin release.

How does this stimulate the ‘Let-Down’ Reflex?

A
  • Neurons stimulate oxytocin release

- Causes myoepithelial cells to contract and eject milk

22
Q

How is the Ovarian Cycle inhibited?

A
  • Neurons in Arcuate Nucleus and Preoptic area of HT are inhibited are inhibited
  • This leads to a fall in GnRH levels
23
Q

With reference to suckling, what 2 things determine length of a ovulation and amenorrhea?

A

Intensity and frequency

24
Q

Describe the changes in milk volumes and content as production is established

A

Initially;

  • Low milk volumes
  • Colostrum is made (High amounts of fat and Immunoglobulins)

As production is established;

  • 800ml of milk is made per day
  • Content changes
25
Q

What are 5 way breast milk protects the baby from infection?

A
  1. Lactoferrin (antioxidant)
  2. Populates baby’s gut with non-pathogenic flora
  3. Presence of Bacteriocidal enzymes
  4. Contains specific Immunoglobulins
  5. Contains Lymphocytes and Granulocytes
26
Q

What is Puerperal Mastitis?

What is the cause typically?

A
  • Milk accumulation in breast leads to inflammation, with or without infection
  • If mother doesn’t feed with both breasts, so milk builds up in Lactiferous ducts of unused breast
27
Q

In Puerperal Mastitis, if infection is present, what is the usual organism present and what can it lead to?

What is treatment of Puerperal Mastitis?

A

Staph aureus, can lead to abscess formation

First line;
- Continue feeding and increase frequency especially on affects side

No improvement after 24hrs;
- Antiobiotics

28
Q

What happens when lactation ceases?

A
  • Milk accumulates in alveoli of breast causing
  • Distension and atrophy of glandular epithelium

Thus effects of local mechanical factors suppress milk secretion rather than hormonal changes

29
Q

What drugs can be given to artificially suppress lactation?

Suggest 1 example

A

Dopamine agonists

E.g Bromocriptine

30
Q

Can women get pregnancy before the return of menstruation?

A

Yes

31
Q

After delivery, secondary haemorrhage can occur.

How does it usually present?

What are 2 typical causes?

A

Prolonged or excessive bleeding once mother has returned home

  • Infection (Endometritis)
  • Retained products of conception
32
Q

Which cells make milk and which cells release milk

Which hormones stimulate the cells

A

Make: Mammary alveolar cells stimulated by PRL
Release: Myoepithelial cells stimulated by Oxytocin
