.
Causes of childhood hypertension?
White coat HT
Organic: renal, cardiac, endocrine
Lifestyle, familial (more and more these days)
End organ damage of HTN
Eyes
LVH
Kidneys(proteinuria)
Malignant HT? Symptoms? How to treat?
Headaches Blurry vision Nausea-vomiting Symptoms of raised ICP Slow-reduction of BP
Podocyte dysfunction get?
Proteinuria
Endothelial or BM dysfunction you get?
Haematuria
Haematuria: 3 things to consider for DDx
Pain
BP
Any proteinuria?
Always do what after urine dipstick?
Do a formal microscopy
Medical renal disease causes?
Hypercalciuria (crystals irritating) Thin BM disease Alport syndrome: X-linked GN -IgA, HSP Coagulopathy
Urological causes of haematuria?
Calculus
Tumour
Stricture
Trauma
How to assess proteinuria
24 hr collection
Spot collection
Glom HT causes?
Hyper filtration
Compensate for podocyte loss
Increased podocyte loss
Podocyte regenerates?
Nope
If find protein in urine, then do what?
Protein creatinine ratio
Minimal change disease cause?
Triggered by infection
Atopic
What age Minimal change disease?
Age 2-10
How to treat Minimal change disease?
Steroids: 2 weeks of high dose

FSGS, MPGN, SLE
Danger of Minimal change disease?
Relapses
Nephrotic syndrome def’n?
Acute inflammation, impaired filtration
Nephrotic syndrome you see what?
Haematuria - macroscopic
Proteinuria
Renal impairement, raised creatinine
Oliguria
What to use to visualize cells in urine in nephritic syndrome?
Phase contrast microscopy
Paediatric nephrotic syndrome, common cause?
Post-strep GN 2-4 weeks after
But any GN like SLE, IgA can cause it

Long term risk of HSP?
Renal: nephritis - looks like IgA
Management of HSP?
acute - Steroids
Doesn’t prevent kidney involvement
HSP don’t forget?
Follow up, can take up to 6/12 for renal involvement in HSP to show up.
