comment Why is the administration of exogenous Anti-D not harmful to the foetus?
That's an excellent article, thank you. I had wondered if they used primarily IgG2 to reduce placental transmission but this is not the case (the article indicating IgG1 and IgG3). If a 125 unit dose can neutralise only 1.25 ml of D+ve blood and not all of it crosses the placenta then this is likely to be an insignificant dose to cause harm. I assume this could cause harm with a greater number of repeated doses after sensitising events but I think this is sufficient evidence to say that it is indeed a dose dependent phenomenon. Thanks!

comment Can systemic intravascular thrombosis cause brain infarction?
@WYSIWYG duly added a couple of examples of references, the phenomenon is very well known and understood so others viewing the question may find it easier to search for Atrial Fibrillation and Stroke

comment Do Penicillin based antibiotics affect birth control?
As I recall from pharmacy teaching, this is one of those things where it was theorised that it might happen due to damaging gut flora which reduces reuptake of oestrogen in the gut, therefore physicians took a cautious approach and gave advice to use barrier methods in addition when taking antibiotics and the OCP

comment What does irregular heartbeat mean in simple language?
@Masi well, this is a Biology Q&A site so answers should really focus on the biological aspects of the question. The original question "why do irregular heartbeats happen and what are it's implications short and long term" is succinctly answered in the above without over complication.
