166
Q

WT1/WT2: gene product and associated tumor(s)

A
(no listed gene product)
Wilms tumor (nephroblastoma)
167
Q

alkaline phosphatase (tumor marker)

A

mets to bone or liver, Paget dz of bone, seminoma (placental ALP)

168
Q

alpha-fetoprotein (tumor marker)

A

HCC, hepatoblastoma, yolk sac (endodermal sinus) tumor, mixed germ cell tumor

169
Q

beta-HCG (tumor marker)

A

hydatidiform moles and choriocarcinomas (gestational trophoblastic dz), testicular cancer, mixed germ cell tumor

170
Q

CA 15-3/CA 27-29 (tumor marker)

A

breast cancer

171
Q

CA 19-9 (tumor marker)

A

pancreatic cancer

172
Q

CA 125 (tumor marker)

A

ovarian cancer (any peritoneal irritation increases CA 125)

173
Q

calcitonin (tumor marker)

A

medullary thyroid carcinoma

174
Q

CEA (tumor marker)

A

very nonspecific, but ~70% of colon and pancreatic cancers produce; also made by gastric, breast, and medullary thyroid carcinomas

175
Q

chromogranin (tumor marker)

A

neuroendocrine tumors/carcinoid

176
Q

PSA (tumor marker)

A

prostate cancer; can also be elevated in BPH and prostatitis, questionable risk/benefit

177
Q

S-100 (tumor marker)

A

melanoma, Schwannoma

178
Q

tartrate-resistant acid phosphatase (TRAP) (tumor marker)

A

hairy cell leukemia

179
Q

anti-Yo, anti P/Q, and anti-Hu abs

A

paraneoplastic cerebellar degeneration

180
Q

renal clearance equation

A

C = UV/P

181
Q

GFR equation

A

GFR = U(inulin)V/P(inulin) = C(inulin)
inulin freely filtered, neither reabsorbed nor secreted
most of the time use creatinine clearance (approximate; slightly overestimates d/t moderate secretion)

182
Q

effective renal plasma flow equation

renal blood flow equation

A

eRPF = U(PAH)V/P(PAH) = C(PAH)
PAH both filtered and secreted
RBF = RPF/(1 - Hct)

183
Q

filtration fraction equation

A

FF = GFR/RPF; normal 20%

184
Q

filtered load equation

A

GFR x Px

185
Q

Winters formula

A

predicted respiratory compensation for simple metabolic acidosis; if measured PCO2 differs significantly from predicted, mixed acid-base disorder likely
PCO2 = 1.5[HCO3-] + 8 +/- 2

186
Q

anion gap calculation

A

Na+ - (Cl- + HCO3-)

normal range: 10-12
