Endocrine Flashcards
Initial test in Hyperthyroidism
TSH
when to repeat thyroid function test after stating treatment
4-6 weeks
most serious complication of graves ophthalmopathy
Optic nerve compression
antithyroid DOC for thyroid storm
PTU
best treatment for hypothyroidism
Levothyroxine
MCC of hypothyroidism worldwide
Iodine deficiency
mountain regions , Alps, Andes
MCC of hypothyroidism in iodine sufficient areas
Hashimoto thyroiditis (AI) and iatrogenic (tx for hyperthyroidism), post RAI
thyroid nodule with low TSH, what is the test?
thyroid scan–> is indicated if the TSH is suppressed to demonstrate HYPERFUNCTIONING state
Toxic adenoma –> mgnt: RAI
Thyroid nodule with high TSH, what is the test?
Ultrasound guided FNAB - may be not hyperfunctioning state
what drug inhibits cortisol synthesis at the level of 11b-hydoxylase, ONLY adrenal inhibiting medication administered to pregnant women with cushing syndrome
Metyrapone
it inhibits the early steps of steroidogenesis
Ketoconazole
MCC of mineralocorticoid excess
Primary Hyperaldosteronism
MCC of cushingoid features
Iatrogenic Hypercortisolism
MCC of Cushing’s syndrome OVER ALL
MEdical use of glucocorticoid for immunosuppression for the treatment of inflammatory disease
primary cause of DEATH in Cushing
Cardiovascular Disease
Parameters to diagnose DM`
HbA1c - >/6.5 %
FPG - >/126/mgdL (7mmol/L)
2 hr, 75g OGTT - >/200mgdl (11mmol/L)
RBS - >/200mgdl (11mmol/L)l
what need to be assessed in DM ANNUALLY
Neuropathy
Nephropathy
Lipids
what need to be assessed in DM, 2x/yr
BiAnnual eyes and feet exam
How many times to assessed HbA1C in a yr?
2-4x a yr
when to consider DUAL combination therapy in DM?
Consider combination Injectable therapy when A1c, RBS ?
DUAL - >/9%
Injectable - Hba1c 10%, RBS >/300mg/dL
Anti DM promotes WEIGHT GAIN
Sulfonylureas
TZD
Insulin
Anti DM promotes WEIGHT LOSS
Metformin
SGLT2 inhibitor
GLP1 receptor agonist
Anti DM that is WEIGHT NEUTRAL
DPP4 inhibitor
Drugs with MOA of increase insulin secretion
Sulfonylureas: Glimepiride, Glipizide
DM Drugs with MOA of INSULIN SENSITIZERS
metformin - reduces hepatic glucose production
TZD: Pioglitazone - react on PPAR-gamma
DM Dugs that inhibit intestinal absorption of sugar, it blocks the enzymes that breakdown complex carbs
Alpha- glucosidase inhibitor: Acarbose, Vogilbose, MIglitol
Insulin prep with long half live (24 hrs)
basal insulin analogs: Glargine, Detemir, Degludec
Onset of action and duration of Rapid acting insulin
RAI: Lispro, Aspart, Glusiline
<15mins, duration: 2-4hrs
target LDL in DMT2 with very high risk CV
<55mg/dl
target LDL in DMT2 with high risk CV
<70mg/dl
target LDL in DMT2 with NO RF
<100mg/dl
target LDL in NONDIABETIC
<130mg/dl
first defense against HYPOGLYCEMIA
decrease insulin secretion
2nd - Glucagon
3rd - Cortisol
Target goal in adults with DM:
HbA1c, pre-prandial, post-prandial, BP
HbA1c - <7%
Pre-prandial - 4.4-7.2 mmol/L
Post - prandial - <10
BP - 140/90 –> if with CKD/CVD: <130/80
most effective therapy in diabetic RETINOpathy
PREVENTION
MC pattern of dyslipidemia
hypertriglyceridemia
low HDL cholesterol level
TRIAD of DKA
Hyperglycemia
HAGMA
Ketosis
difference of HHS to DKA
HHS - Insulin deficiency – hyperosmolarity, osmotic diuresis – dehydration
glucose level >600
dominant ketone in ketosis
3 hydroxybutyrate
major nonmetabolic complication of DKA therapy
Cerebral edema
method of choice to determine the thyroid SIZE aacurately
Ultrasound
drug NOT used in thyroid Storm
Amiodarone – exacerbate by giving excess Iodide
High TSH, Normal FT4
Mild subclinical hypothyroidism
high TSH, Low FT4
Primary hypothyroidism
Autoimmune hypothyroidism
low TSH, high FT4
primary thyrotoxicosis: Graves, multinodular goiter, toxic adenoma
low TSH, normal FT4
Subclinical hyperthyrodism
t3 toxciosis
monitoring on treatment of thyroid?
stable px?
adjustment of tx?
on tx; 3-4mos
stable: 6-12 mons
adjust: 6-8 weeks
size of the nodule to be palpable
> 1cm in diameter
most accurate diagnostic in Cushing syndrome
24hr urine cortisol
best initial diagnostic test in Cushing syndrome:
1mg overnight Dexa suppression test and 24 hr urine cortisol
TRIAD of Pheochromocytoma
Profuse sweating
headaches
Episodic palpitations
human monoclonal antibody to RANKL –>inhibits the formation of osteoclast
denosumab
