baja_blast  You're almost certainly right that it's mitral valve endocarditis. The murmur is accentuated by Expiration, consistent with lEft-sided murmurs.

tinydoc  I thought the elevated Estrogen and progesterone depress the function of Prolactin until delivery. I guess you needed to know that it decreases its function by downregulating receptors or something as opposed actually decreasing the prolactin production. I picked gonadotrophs. This was a fair question but I reasoned it out and arrived at the wrong conclusion. +7  
maxillarythirdmolar  Specifically, the estrogen is stimulating lactotrophs as progesterone is preventing the prolactin from actually working on the breasts. So it's the estrogen that is stimulating the lactotrophs to grow, and you would see the effects of this growth if it weren't for the progesterone preventing the action of prolactin (their secretory product) on the breasts. +9

alexxxx30 spinocerebellar tract does 4 things to know 1. proprioception in the Romberg test 2. intention tremor if damaged 3. shin to knee test 4. dysdiadochokinesia (being able to rapidly pronate/supinate the upper extremity) yes the patient has proprioception issues, but the other symptom of vibration loss points us more to a fasciculus gracilis issue. If the patient had presented with proprioception and and intention tremor then we would think spinocerebellar +2  
alexxxx30  adding to my comment^ I would commit these 4 things to memory as I have gotten several questions concerning this topic (there were 2 questions on this exam where spinocerebellar tracts are involved). Memorize them and it might get you 1-2 extra points! +  
solidshake  Just to clarify a point, Spinocerebellar tracts are not tested by the Romberg Test. Romberg tests conscious proprioception that is done by the dorsal columns. Spinocerebellar tracts are used for Unconscious proprioception. Look up tabes dorsalis in First Aid. One of the positive indicators is a positive romberg test, which shows that the dorsal columns have been damaged thus affecting conscious proprioception and thus impaired balanced on standing with the eyes closed +

194orbust  per UWorld, "cortisol exerts a permissive effect on many hormones to help improve the response to a variety of stressors. For example, cortisol increases vascular and bronchial smooth muscle reactivity to catecholamines". FA also uses the effect of cortisol on catecholamine responsiveness as the lone example for a permissive drug interaction (FA2018 pg 229). The difference here is that we're talking about exogenous glucocorticoid and adrenergic agonist. I guess it was expected for us to assume that the mechanism is analogous for the analogous drugs +13  
maxillarythirdmolar  I'm sure it's related to the activating effect of Cortisol on phenylethanolamine-N-methyltransferase, converting NE to Epi. Sounds like a synergistic thing to me. (FA.83) +3  
feeeeeever  My logic is probably flawed, but I also thought that if cortisol has the ability inhibit COX, LOX, and NFKB you can reduce inflammation and bronchoconstrictive mediators. Therefore, the B2 agonists would have a greater effect since things like LTB4 will be reduced. +1

maxillarythirdmolar  For anyone wanting to understand why^ the tl;dr is that prolactin gets cleaved into two toxic metabolites. Treatment is something like bromocriptine (and therefore no more breast feeding) to stop prolactin release. Lastly, you can treat with regular HF meds. +1

maxillarythirdmolar  To take it a step further, Goljan mentions that there are a myriad of things circulating in the body, often in a 1:2 ratio of free:bound, so in states like this you could acutally see disruption of this ratio as the body maintains its level of free hormone but further increases its level of bound hormone. Goljan also mentions that you'd see the opposite effect in the presence of steroids and nephrotic syndromes.

hello  Yep, and I think what we are supposed to take from this Q is: The only info. we have for this patient is that he ended chemo 2 months ago and has been calling the doctor a lot -- this is supposed to mean he has been calling a lot since ending chemo 2 months ago. His frequent calls starting after ending chemo and within 3 months of the stressor fits with the above-stated definition of "adjustment disorder" with anxiety. I stressor in this case could possibly be either the actual illness or the ending of chemo/treatment. It probably does not matter much in this case. +4

meningitis  Does anyone know the relevance of the stem saying: "during this time she also has been crying frequently"? +44
