62
A 35 year old African American Female comes into your office with a known history of SLE, upon inspection you find Subendothelial Immune Deposists, and upon EM you see "wire loops" to the renal glomerular capillary, which is also present in the mesangium.

What is her best diagnosis?
How would we treat this?
(Class IV) Focal and Diffuse Proliferative Lupus Nephritis
Tx the underlying disease. (Lupus)

If he had toxic injury you would see continous necrosis at those locations with swelling and vacuolization.
Necrotic Tubules cells sloughing off and causing obstructed flow.

93
A 28 year old Swedish man comes into your clinic. He has flank pain and hematuria. His BP is noted to be high, and he says that he regularly takes hypertension medication for it. He says that he has a tendancy for kidney stones, but has normally not sought out medical care -- as he lives a typical swede life.

What do both of the genes (for the 2 types) code for, and their action?
PKD2 Gene
Polycystin 2
They both code for polycystin proteins that affect tubular cilia and calcium flux --\> this causes problems with growth and differentiation --\> causing cell proliferation and fluid accumulation --\> cyst formation and fibrosis!
94
A 28 year old Swedish man comes into your clinic. He has flank pain and hematuria. His BP is noted to be high, and he says that he regularly takes hypertension medication for it. He says that he has a tendancy for kidney stones, but has normally not sought out medical care -- as he lives a typical swede life. You decide to biopsy his kidney and find multiple cystic lesions throughout. You diagnose him with Adult Polycystic Kidney Dz

96
A 1 week old baby is brought to you (lucky duck). You notice enlarged cystic kidneys (that were noted to be that way at birth by the OB/GYN) and you notice hepatic fibrosis (with your eyes of osteopathy). The baby has Portal HTN, and mild splenomegaly. You realize, at once, that this baby has Childhood Polycystic Kidney Dz.
If this had been a 4 year old baby that was brought to you, how would that have affected your prognosis?
Better --\> they would have been in the infantile range and would have only about 20% of their collecting ducts be cystic -- but have hepatic fibrosis and failure.
They might live into early childhood, but would die around that time.
97
A 1 week old baby is brought to you (lucky duck). You notice enlarged cystic kidneys (that were noted to be that way at birth by the OB/GYN) and you notice hepatic fibrosis (with your eyes of osteopathy).

Prognosis?
**Esophageal Varices,** due to heavy hepatic fibrosis causing portal HTN.
Most die in adolescence.

In the Medulla
No, its a Benign Medullary Sponge Kidney
No Inheritance (so it can be unilateral or bilateral)
100
a 3 year old infant is brought to your clinic by her mother. She has noticed that little Debbie Ann-Reigxh *(the X is silent, because her father left her, and the no-good-for-nothing man doesnt deserve the X in this child).* She has noticed the baby has had excessive thirst, and lots of urination. She also is worried because she doesnt think that her baby is growing in comparison to her sisters baby (whom is much uglier -- her words not mine).

Do you agree?
The tumors would have what shape of scar?
These tumors arise from what?

No, This is Renal Oncocytoma (it is commonly confused for RCC)
Central Stellate Scar
Type A Intercalated Cells of the Renal Cortical Collecting Duct
Lots of Mitochondria in the cells!

Sharon, the abnormally nosy woman has shown up to your clinic again -- after berating a 18 year old for being "suspicious". She now states that her new baby has many congenital defects of the lower urinary tract -- and wants you to explain what the most common one is (or else your yelp review will be getting slammed).

123
Sharon, the abnormally nosy woman has shown up to your clinic again -- after berating a 18 year old for being "suspicious". She now states that her new baby has many congenital defects of the lower urinary tract -- and wants you to explain (or else your yelp review will be getting slammed).
She now states her baby is peeing out his belly button, and she thinks he needs to take some vitamins -- because clearly B4 is deficient. You sigh, and disagree and tell her . . .
Your baby has a **Patent Urachus**
**(**He doesn't, shes a terrible parent)
124
Sharon, the abnormally nosy woman has shown up to your clinic again -- after berating a 18 year old for being "suspicious". She now states that her new baby has many congenital defects of the lower urinary tract -- and wants you to explain what the most common one is (or else your yelp review will be getting slammed).
Lastly she decides to tell you that her little guy had his bladder on the outside of his body, and wants to know if she should be worried -- as no one seemed alarmed on her "Parents-Against-Everything-Good-For-Your-Child" Website.
He needs surgery (first of all), and he is at risk for infections, that can cause Pyelonephritis (Due to infections traveling up)
He is also at risk for Adenocarcinoma of the bladder
