Nephrology Flashcards
Wilms tumour?
Deletion on the short arm of chromosome 11
Transitional cell carcinoma
Smoking, analgesic nephropathy, β nephropathy, schistosomiasis,
What cancer is associated with cadmium exposure
Renal cell carcinoma
What is the most common renal manifestation in ankylosing spondylitis?
Amyloidosis followed by IgA nephropathy
Others: These include mesangioproliferative glomerulonephritis, membranous nephropathy, focal segmental glomerulosclerosis, and focal proliferative glomeruleonephritis as well as kidney stones
Three nephropathy associated with AS:
AA amyloidosis (large kidneys)- heavy proteinuria
Ig A nephropathy- protein and blood
NSAID nephropathy
Autosomal dominant PKD
Short arm of chromosome 16. 10% of cases is chromosome 4. Liver cysts may be present and cerebral aneurysms. Mitral valve prolapse and aortic incompetence may be seen.
Alport Syndrome
autosomal recessive or x-linked pattern with abnormalities in Type IV collagen. Patients present with sensorineural hearing loss and nephritis. Angiotensin inhibitors may slow progression of renal disease. Patients may have progressive retinopathy
Lupus nephritis
deposition of immune complexes between GBM and vascular endothelium (sub endothelial) leading to attraction of complement which can present with hematuria (proliferative and mesangial glomerulonephritis). Complexes may also be deposited between GBM and bowman’s capsule which is subepithelial leading to proteinuria (membranous nephropathy)
Renal biopsy findings in Hep C
cryoglobulins with type 1 mesangiocapillary glomerulonephritis
Renal biopsy findings inGPA
granulomas seen with glomerulonephritis
Renal biospy in HIVAN
focal segmental flomerulosclerosis
What renal diseases is RA associated with?
Membranous nephropathy, Renal amyloidosis, analgesic nephropathy and rheumatoid vacsulitis
Cystinuria
may present with urolithiasis. On urine analysis hexagon-shaped crystals may be seen. Sodium nitroprusside urine test is positive (turns purple). Cystine stones are poorly radiopaque. Usually seen on CT, not X-ray.
Struvite stones
Caused by UTI. Are radiopaque. Present with alkaline urine (also seen with calcium stones)
Uric acid stones
rhomboid crystals, radiolucent on X-ray
Biopsy findings in post-streptococcal glomerulonephritis?
subepithelial humps
