Raised oestrogen(for a male)
How is androgen insensitivity syndrome managed?
Specialist MDT: paeds gynae, urology, endo, psych
Counselling-generally raised as female

Vaginal dilators/surgery to create an adequate vaginal length

Can be caught from someone with shingles
How is chicken pox diagnosed?

System distribution can produce necrosis of myocardial, neural and renal tissue
How might a patient with diphtheria present?
