Q

found within macrophages (siderophages), breakdown of blood (blood vessel damage)
turning tumor brown color

A

22
Q

having GI issues
bone pain in legs

A

primary hyperparathyroidism (or MEN1)

23
Q
A

parathyroid adenoma

24
Q
A

adenoma
on bottom is normal parathyroid

25
Increased PTH due to a disease other than the parathyroid Most common cause is chronic renal failure
secondary and tertiary hyperparathyroidism
26
caused by oversecretion of parathyroid hormone low phosphate high PTH and calcium
primary hyperparathyroidism
27
caused by vitamin D deficiency high phosphate and PTH low calcium
secondary hyperparathyroidism
28
caused by chronic renal failure high phosphate and calcium very high PTH
tertiary hyperparathyroidism
29
common cause of hypercalcemia in elderly
cancer
30
Most common cause of this is women over the age of 50 after menopause
PTH-independent hypercalcemia
31
______ carcinoma is common cause of hypercalcemia
squamous cell carcinoma
32
Rare, decreased PTH due to autoimmune disorders, DiGeorge syndrome and surgical excision
hypoparathyroidism
33
DiGeorge syndrome
34
Symptoms of hypoparathyroidism but with an increased PTH level End organ resistance to PTH, inactive or decreased expression of PTH receptors GNAS gene mutation coupled to PTH receptor Short stature, round (full) face, brachydactyly
Pseudohypoparathyroidism
35
due to PTH receptor deficiency (low serum calcium and normal PTH)
Pseudohypoparathyroidism
36
Albright's syndrome (Pseudohypoparathyroidism)
37
Differ from other hereditary cancer syndromes in that most neoplasia grow in hormone-secreting glands
multiple endocrine neoplasia
38
Well-defined hormonal syndromes with excess hormone production Asymptomatic patients can be identified with excess hormone that serve as tumor markers for screening, diagnosis and therapy
multiple endocrine neoplasia
39
3 P's pituitary adenoma, parathyroid hyperplasia, pancreatic tumors
MEN1
40
parathyroid hyperplasia medullary thyroid carcinoma pheochromocytoma
MEN2A
41
mucosal neuromas marfanoid body habitus medullary thyroid carcinoma pheochromocytoma
MEN2B
42
MEN1
43
MEN2
44
2 theories for this, but pathophysiology is unclear
adrenal gland hemorrhage
45
First identified as an outcome in children with Neisseria meningitis sepsis Rare but life-threatening disorder that involves bilateral adrenal hemorrhage
Waterhouse-Friderichsen Syndrome
46
Following a bacterial or viral infection, an acute clinical presentation including: Abdominal pain Fever Chills Headache Nausea and vomiting Joint and muscle pain Skin rash Loss of consciousness
Waterhouse-Friderichsen Syndrome
47
Develops into disseminated intravascular coagulation (DIC) and shock
Waterhouse-Friderichsen Syndrome
48
common cause of waterhouse-friderichsen syndrome
meningococcal meningitis
49
Increased release of cortisol and adrenaline Adrenocortical hemorrhage
waterhouse-friderichsen syndrome
50
Septicemia > Endotoxemia > Adrenal hemorrhage (90%) > DIC > Shock
Waterhouse-Friderichsen syndrome
51
in child, following bacterial or viral infection and has fever
Waterhouse-Friderichsen Syndrome
