Second pass deck 02 Flashcards
biphasic stridor in an infant that improves with neck extension?
vascular ring
_________________ is elevated in acute intermittent prophyria
urinary porphobilinogen
what are the most common neuroimaging findings in schizophrenia?
- loss of cortical tissue volume
- (lateral) ventricular enlargement
- DECREASED hippocampal volume
what are the neuroimaging findings in OCD?
structural abnormalities in the orbitofrontal cortex and basal ganglia
- third trimester female
- red papules within striae with sparing of the umbilicus, sometimes extending to extremities
- no lab findings
pruritic urticarial papules and plaques of pregnancy
- second or third trimester female
- intolerable, generalized pruritis that is especially significant on the palms and soles and worsens at night
- possible skin excoriations
intrahepatic cholestasis of pregnancy
gonadotropin-dependent precocious puberty results from ____________ and LH levels are_______
- premature activation of the HPG axis
- high
patients with gonadotropin-DEPENDENT precocious puberty require what test?
MRI (with contrast)
what is the treatment for gonadotropin-dependent precocious puberty?
GnRH agonist therapy (to prevent premature epiphyseal plate fusion and maximize adult height potential)
patients with gonadotropin-INDEPENDENT precocious puberty require what test?
US of adrenal glands, ovaries, testes
water hammer / Corrigan pulse = ?
aortic regurgitation
symptomatic hypertrophic cardiomyopathy is treated with:
negative inotropic agents (BBs, verapamil, disopyramide)
*BBs are typically first line - prolong diastole and decrease myocardial contractility, decreasing LVOT obstruction
how do beta adrenergic agonists affect potassium?
- intracellular shift
- also stimulates insulin release, further promoting intracellular shift
resultant HYPOkalemia
what is the reason for the abnormal bleeding associated with menarche?
immaturity of the developing HPG axis that produces inadequate quantities and proportions of GnRH, and subsequently FSH and LH
in patients with abnormal uterine bleeding, bleeding after exogenous progesterone administration confirms:
normal endogenous estrogen production and proliferative endometrium
*eliminates causes of estrogen deficiency (primary ovarian insufficiency), endometrial abnormalities (intrauterine adhesions), and outlet tract abnormalities (imperforate hymen)
