May 4th (star Wars Day) Flashcards
Which type of pneumocytes produce more pneumocytes? (Stem cell)
Type 2.
Confidence interval and relative risk
RR=1 = no association. Over/under 1 = association. If it is large enough to fit into 95% confidence interval, it is significant.
Method of action of atrial natriuretic peptide/ANP and BNP
Bind TM protein linked to guanylyl cyclase -> to protein kinase -> dilation.
How to calculate change of child having autosomal recessive disease
(Chance a random kid gets it with carrier parents= 1/4) X (chance a mom is a carrier) X (chance dad is a carrier)
Or
(Chance of dad giving allele = q if gen pop) X (chance of mom giving allele (50% if carrier)

Function: External rotation
Innervation: suprascapular nerve
Rotator cuff muscles
SItS Supraspinatus: abduction Infraspinatus: external rotation Teres minor: adduction/external rotation Subscapularis: adduciton/Internal rotation
Intrapartum antibiotic prophylaxis
1st line: peniccilin
2nd line: ampicillin
Type 1 diabetes at risk for what?
Other autoimmune
Hashimoto
Addison’s
Increased cortisol causes what?
Insulin resistance (therefore decreased causes insuilin sensitivity)
Addisons affects what part of the adrenals
ALL THREE layers of the cortex. (Aldosterone, androgens, cortisol)
Denge fever infectino and reinfection
First: hemmorhaggic. Myalgias, thromboytopenia, petechiae
Second: worse. Different serotype
How to diagnose congenital lactase deficiency?
Stool pH (down)
Breath hydrogen test (up)
Stool somotic gap (increased)
Antiogensin II receptor Blocker (ARBs)
Losartan: block angiotensin II
No ACE affected therefore no bradykinin affected therefore no cough
Function of BRCA 1/2 genes
DNA repair. Tumor suppressor
Embryologic origin of Anterior pituitary
Ratchke’s pouch (surface ectoderm)
Acute tubular necrosis:
Proximal tubular cell ballooning
Vacuolar degeneration
Oxalate crystals (not calcium oxylate)
Ethylene glycol poisoning
Melatonin agonist
Ramelton, safe for elderly
Superior vena cava syndrome
Cmopression of vein. Easy by mediastinal mass
Puff face, neck, upper extremities
Dizziness/headache if cerebral edema.
Mostly lung cancer/ then non-hodkin lymphoma
Psoriais
Hyperparkaratosis Acanthosis Rete redige elongation No stratum granulocum. Munro microabscess
Muncro microabscess
Neutrophils cluster in superficial dermis and stratum corneum
Fabry disease
Alpha-galactosidase A deficiecny
Accumulation of sphingolipid globotriaosylceramide.
Kidney and CerebroV disease
Chemo receptors
Central chemoreceptor: medulla, decrease pH of cerebrospinal fluid (increased Paco2 That diffuses and forms H+) = increased respiration.
PEripheral: carotid/aortic boies. Arterial paO2 (hypoxemia). Also a little PaCO2/H+.
Pulmonary stretch receptor: regulate duration Of inspiration depending on lung distension. Protect from hyperinflation.
Difference between bipolar 1 and 2
1: mania, more than one week, psychotic symptoms, severe.
2: four days, just hypomania. Lack of sleep and high energy normal.
Rubeola (measles) or rubella
Not vaccinated. Febrile maculopapular rash that begins at face and spreads to trunk.
Differentiate by postauricular lymph = rubella
Pseudogout vs gout
Neagtive bifringent crystal
Needle-shaped
Cholcicine side effect and use
Second line treatment for gout (NSAIDs but dont use with peptic ulcer)
Side-effect: prevent tubulin polymerization into microtubule. Also nausea/diarrhea (mucosal cells in GI too affected)
Xantine oxidase use
