GBS is present in the bowel flora of 20–40% of adults (this is called ‘colonisation’). People who are colonised are called
‘carriers’. This includes pregnant women (there is no evidence that its carriage rate is specifically affected by pregnancy).

Women are generally advised to wait for at least 2 years after treatment for breast cancer before
conception.

Cord presentation is the presence of the umbilical cord between the fetal presenting part and the cervix, with or without intact membranes. ( i.e if the cord  is present ABOVE the cervix, with ruptured membranes- this is cord PRESENTATION)

Cord prolapse is descent of the umbilical cord through the cervix  in the presence of ruptured membranes.

Cord prolapse can be occult ( Alongside the presenting part) or OVERT (Past the presenting part)

Bonus info- There is at least one more condition in which the delivery should be delayed for some time after appearance of the condition- Chickenpox ! In varicella rash- planned delivery should normally be avoided for at least 7 days after the onset of the maternal rash to allow for the passive transfer of antibodies from mother to child.

• Anthracyline regimens are safe
• There are fewer data on taxanes, which should be reserved for high-risk (node-positive) or metastatic disease.
• Tamoxifen is not used until after delivery.
• Trastuzumab  is contraindicated during pregnancy.
• Haemopoietic growth factors (granulocyte colony stimulating factor) may be employed to ameliorate chemotherapy-induced neutropenia.

It is not necessary to administer anti-D Ig to D negative females without childbearing potential, or males who receive D positive platelets.

Methotrexate adjuvant therapy should not be used for expectant management as it is of unproven benefit and has significant adverse effects.

Caesarean section is the recommended mode of delivery in cases of cord prolapse when vaginal birth is not imminent in order to prevent hypoxic acidosis.
Category 2 caesarean birth can be considered for women in whom the fetal heart rate pattern is normal, but continuous assessment of the fetal heart trace is essential.

In case of cord prolapse in advanced labor , delivery should be expedited.

A document on categories of Caesarean section can be found here-CLICK HERE

A systematic review reported that women with one, two, or three or more previous caesarean deliveries experience a 1%, 1.7% or 2.8% risk of placenta previa in a subsequent pregnancy. ( Source- Birth After Previous
Caesarean Birth Green-top Guideline No. 45 ).

Assisted reproductive technology ( RR- 3.71, OR 2.67)and maternal smoking ( OR 1.42)  increase the risk of placenta praevia.

Non-hormonal contraceptive methods are recommended.

According to UKMEC- For women with 'Current breast cancer' , Cu IUCD is Category 1 , all other contraceptive methods are category 4.

For women with 'Past' breast cancer' , Cu IUCD is Category 1 , all other contraceptive methods are category 3.

The recommended dose is - 3 g intravenous benzylpenicillin be given as soon as possible after the onset of labour  and 1.5 g 4 hourly until delivery.
The first dose should be given at least 4 hours prior to delivery.

Routine ultrasound screening is not useful. Selective ultrasound screening can be considered for women with breech presentation at term who are considering vaginal birth.

Planned VBAC is associated with an approximately 1 in 200 (0.5%)
risk of uterine rupture
