Q

Clinical features of hand, foot and mouth disease?

And management

A

Mild systemic upset - sore throat, fever
Oral ulcers
Followed later by vesicles on the palms and soles of the feet

Management:

  • general advice about hydration and analgeis
  • reassurance no link to cattle disease (comes from a different virus)
  • advise child to stay off school until symptom free - ask parent what school policy is on when child can return after illness

Your child is most contagious in the first 7 days. But the virus can stay in her body for days or weeks after symptoms go away and it could spread through her spit or poop. The best way to prevent that is to wash hands thoroughly. That applies to you, too, after you change a diaper or wipe a runny nose.

Q

What is the rate you should perform chest compressions at for a child?

Q

Pneumonic for the causes of meningitis in a child <3 months

A

GEL

Group B strep
E. coli

Group B strep and e. coli can colonise the maternal reproductive tract and during birth, the baby can acquire these pathogens and become unwell

Listeria meningitis can occur if a women eats food contaminated with listeria while pregnant, as the infection can be transmitted from mother to foetus
