right. he absolutely must remain in the waiting area so that he is at hand to attack his wife whenever her exam ends. go NBME!

meningitis  I guess it was all about not offering battering information in order to not make matters worse since he will figure out that the wife told on him.. Also, its a HUGE STRETCH but the only reason I thought he should stay in the waiting room was just in case the wife died they could detain him and call the police for questioning.
temmy  Also, he should stay there because his wife did not grant him the permission to see him. Patients requests trumps.
nephcard  Doctor should not believe what wife told her. There may be some other reason for injury so batttering information should not be provided. But her wish of not letting her husband in should be fulfilled
charcot_bouchard  No. In real life patient lies. In Board ques they always tell the truth. Unless they make it very obvious. in fact its a board ques rule. So u believe her untill proven otherwise.
drdoom  The prevailing rule of American medicine and law is individual autonomy. No other person is granted “default access” or privilege to another person’s body—that includes the physician! The physician must receive consent from a (conscious) “person” before they become “a patient”. In the same way, the person (the patient) must give consent before anyone else is permitted to be involved in her care, spouses included!

Treatment of acute gouty arthritis Several drugs are effective for terminating the acute gouty attack. Colchicine, nonsteroidal anti-inflammatory drugs (NSAIDs), and corticosteroids are standard approaches. Adrenocorticotropic hormone (ACTH) is also very effective, but has become increasingly scarce or too expensive to be a practical alternative in the US. Regardless of the particular agent chosen, the sooner these drugs are started, the more rapid the response. If a patient cannot take NSAIDs or colchicine, the choice is among oral, intra-articular or parenteral glucocorticoids. Local application of ice packs may help control pain. In some cases, analgesics, including opioids, may be added.

Drugs that affect serum urate concentrations (E.G., ALLOPURINOL), including antihyperuricemic agents, should not be changed, started, or stopped during an attack, as this may worsen the inflammatory response already in progress.

SSRIs produce a sustained increase in extracellular 5-HT in the dorsal raphe (DR), and this leads to autoinhibition of serotonergic neurons.

The most important waste product is ammonia (NH3). This small molecule crosses the blood–brain barrier and is absorbed and metabolised by the astrocytes, a population of cells in the brain that constitutes 30% of the cerebral cortex. Astrocytes use ammonia when synthesising glutamine from glutamate. The increased levels of glutamine lead to an increase in osmotic pressure in the astrocytes, which become swollen. There is increased activity of the inhibitory γ-aminobutyric acid (GABA) system, and the energy supply to other brain cells is decreased. This can be thought of as an example of brain edema of the "cytotoxic" type.

The β-cells have evolved a mechanism to detect the amount of insulin stored and secreted and adjust insulin synthesis accordingly. A granule transmembrane protein called islet cell autoantigen 512 (ICA512), is a crucial part of this feedback control. Insulin granules travel a long distance on tubulin tracks before arriving at the peripheral actin network [125]. Before becoming linked to the cytoskeleton, insulin granules are anchored to actin cortex via ICA512 and β2-synthrophin. Upon activation, the granule membrane fuses transiently to the cell membrane to release insulin. Elevated Ca2+ levels in the meantime activate the protease μ-calpain to cleave away a cytosolic fragment from ICA512. The free ICA512 cytosolic fragment then moves to the nucleus and binds to the tyrosine-phosphorylated transcriptional factor STAT5 to prevent STAT 5 from dephosphorylation, which in turn upregulates insulin transcription [127]. Nuclear free ICA512 cytosolic fragments also bind to sumoylating enzyme PIASγ. The sumoylation of ICA512 by PIAS γ reverses the binding of ICA512 to STAT5 [127]. Hence, the release of insulin from secretory granules is communicated to the nucleus, which serves as a positive feedback mechanism to initiate insulin translation for maintaining an adequate amount of stored insulin.

The four types of hydrocephalus are communicating, noncommunicating, ex vacuo, and normal pressure. Diagnosis is typically made by physical examination and medical imaging.

Hydrocephalus ex vacuo also refers to an enlargement of cerebral ventricles and subarachnoid spaces, and is usually due to brain atrophy (as it occurs in dementias), post-traumatic brain injuries and even in some psychiatric disorders, such as schizophrenia. As opposed to hydrocephalus, this is a compensatory enlargement of the CSF-spaces in response to brain parenchyma loss; it is not the result of increased CSF pressure.

Hypovolemia is a direct loss of effective circulating blood volume leading to:

  • A rapid, weak, thready pulse due to decreased blood flow combined with tachycardia
  • Cool, clammy skin due to vasoconstriction and stimulation of vasoconstriction
  • Rapid and shallow breathing due to sympathetic nervous system stimulation and acidosis
  • Hypothermia due to decreased perfusion and evaporation of sweat
  • Thirst and dry mouth, due to fluid depletion
  • Cold and mottled skin (Livedo reticularis), especially extremities, due to insufficient perfusion of the skin

The most common and severe form of autosomal dominant polycystic kidney disease (ADPKD) results from mutations in PKD1, encoding polycystin-1 (PC1)..


yotsubato  Here we thank FA for failing us yet again. Giving us PKD1, but not polycystin. I got the question right but I just guessed it because nothing else made sense.
usmleuser007  Autosomal dominant polycystic kidney disease 1) occurs in patients with mutations in the gene (PKD1) encoding polycystin-1 (PC1). 2) PC1 is a complex polytopic membrane protein expressed in cilia that undergoes autoproteolytic cleavage at a G protein–coupled receptor proteolytic site (GPS). 3) A quarter of PKD1 mutations are missense variants, though it is not clear how these mutations promote disease. 4) GPS cleavage is required for PC1 trafficking to cilia. 5) A common feature among a subset of pathogenic missense mutations is a resulting failure of PC1 to traffic to cilia regardless of GPS cleavage. 6) Missense mutation in the gene encoding polycystin-2 (PC2) that prevented this protein from properly trafficking to cilia.

Congenital adrenal hyperplasia due to 21-hydroxylase deficiency.


wutuwantbruv  Can't be 17α-hydroxylase because this would present with hypertension and some sort of ambiguous sexual presentation (males) or lack of secondary sexual development (females). Can't be 11β-hydroxylase because this would present with the opposite of the kid's presentation due to the production of 11-deoxycorticosterone (similar effects to aldosterone but not nearly as potent). The other two would not really make sense since there are increased levels of 17-hydroxyprogesterone.

During this initial encounter, we establish what the parents' concerns are, obtain a family history, and ask about previous medical problems. This begins the transition from parent to teen as the medical historian. We next ask parents to wait in the waiting room so that we can speak privately with the adolescent. We interview the adolescent alone, perform a physical examination with a chaperone, and then invite the parents back into the room at the conclusion of the visit to discuss our findings.

Among the most prevalent hematologic abnormalities in patients with rheumatologic disorders are the anemia of chronic disease (ACD), a mild anemia that is generally asymptomatic, and iron deficiency anemia.

In iron-deficiency anemia, the TIBC would higher than 400–450 mcg/dL because stores would be low.

Patients with RA occasionally have concurrent iron deficiency anemia and ACD. When this occurs, the hemoglobin level usually drops to below 9.5 g/dL, and the MCV is less than 80.

Bleomycin is known to cause lung and skin toxicity due to relative absence of hydrolase in skin tissue resulting in decreased metabolism and delayed clearance. Pulmonary complications are common but skin changes are rare and include hyper-pigmentation, plaques, hyperkeratotic lesions, erythema multiforme, alopecia, stomatitis and nail changes. The exact mechanism of skin changes caused by bleomycin is not known. The treatment involves management of underlying disorders or withdrawal of the offending drug.

In sarcoidosis, hypercalcemia normally suppresses the release of PTH and therefore the production of calcitriol (1,25-dihydroxycholecalciferol), but in sarcoidosis and other granulomatous diseases, activated mononuclear cells (particularly macrophages) in the lung and lymph nodes produce calcitriol (1,25-dihydroxycholecalciferol) from calcidiol (25-hydroxycholecalciferol) independent of PTH.

Falling on outstretched hand: scaphoid is most common one to be fractured, lunate is most common to be dislocated. Lunate dislocation can cause acute carpal tunnel syndrome.

The patient needs medical attention immediately, which eliminates obtaining a court order, or transferring her. A nurse does not have the same training and qualifications as a physician, so it would be inappropriate to ask them to examine the patient. Asking the hospital chaplain again could be inappropriate, and would take more time. Therefore, the best option among those given is to ask the patient if she will allow with her husband present.

medpsychosis  The question here focuses on a specific issue which is the patient's religious conservative beliefs vs. urgency of the situation. A physician is required to respect the patient's autonomy while also balancing between beneficence and non-maleficence. The answer choice where the physician asks the patient if it would be ok to perform the exam with the husband present is an attempt to respect the conservative religious belief of the patient (not being exposed or alone with another man in the absence of her husband) while also allowing the physician to provide necessary medical treatment that could be life saving for her and or the child. Again, this allows for the patient to practice autonomy as she has the right to say no. +7

First heart sound (S1) is generated by two heart valves: the mitral valve and tricuspid valve. Nearly simultaneous closing of these valves normally generates a single S1 sound.

CT shows mass on the left side of his abdomen and you’re told it’s intussusception. Asks which part of the GI tract is most likely to cause the pain. I immediately looked for ileocecal junction ... not an answer choice. Why is the answer jejunum (vs. duodenum)?

liverdietrying  The picture is key here. You’re right that ileocecal is most common, but ileo-ileal and jejuno-jejunal are the next most common (I think I might just know this from having done clerkships already, not sure). Ileo-ileal isn’t an answer, so that rules that out. Look at where the arrows are pointing in the picture as well. Its on the L, ruling out appendix and cecum. And the slice is not at the level of the duodenum, ruling out that answer. So by process of elimination based on the picture you could get this one too. +2

In sarcoidosis, hypercalcemia normally suppresses the release of PTH and therefore the production of calcitriol (1,25-dihydroxycholecalciferol), but in sarcoidosis and other granulomatous diseases, activated mononuclear cells (particularly macrophages) in the lung and lymph nodes produce calcitriol (1,25-dihydroxycholecalciferol) from calcidiol (25-hydroxycholecalciferol) independent of PTH.
