The Stem is describing hemochromatosis, characterized by abnormal iron sensing and increased intestinal absorption. This increases Iron, increasing ferritin. In response, TIBC is decreased, which increases transferrin saturation as there is less circulating carrier molecules.

With excess iron in the blood, it will accumulate in tissues including the liver, skin, pancreas. Sequelae include dilated cardiomyopathy, hypogonadism, diabetes, arthropathy 2/2 calcium pyrophosphate deposition, nd Hepatocellular Carcinoma

hello  I think you made one slight mistake. TIBC = total iron binding capacity. It is synonymous with "transferrin saturation". This patient has increased transferrin saturation aka increased TIBC. The transferrin molecules are saturated -- it is incorrect to say "as transferrin saturation increases, there is less circulating carrier molecules." It is more correct to say that the amount of free (unbound) transferrin is decreased.

The primary mechanism of action of colchicine is tubulin disruption. This leads to subsequent down regulation of multiple inflammatory pathways and modulation of innate immunity.

Patients with fungemia 2/2 to Candida albicans should recieve and Echinocandins antifungal agent idsa practice guidelines

Echinocandins inhibit the synthesis of beta (1,3)-D-glucan, an essential component of the cell wall of susceptible Aspergillus species and Candida species

Encapsulated organisms run rampant in patients who have no spleen, whether physically or functionally. (Recall the wide-array of sequalae sickle cell patients experience thanks to their functional autosplenectomy.)

sympathetikey  Agreed -- went with E. Coli like a dingus, just because I didn't associate DIC with S. Pneumo. Thought it was too easy. +  
chillqd  Isn't E. Coli also an encapsulated organism? What makes Strep pneumo more likely in this question just because its the more common cause? +1  
studentdo  Pseudomonas aeruginosa is encapsulated as well. I think the right answer has to do with DIC but why? +1  
mgoyo89  The only reason i found was S. pneumo is more common, I went with Pseudomonas because of the "overwhelming sepsis" :( +  
kard  Everyone is correct about the Encapsulated microbes, but this is one of those of "MOST LIKELY", and by far the most likely is S.Pneumo>>H.infl>N.Mening. (omitting that patients with history of splenectomy must be vaccinated. +

While I can get on board with Adjustment Disorder, I don't see how this answer is any better than Somatic Symptom Disorder. From FA:

Variety of bodily complaints lasting months to years associated with excessive, persistent thoughts and anxiety about symptoms. May co-appear with illness.

SSD belongs in a group of disorders characterized by physical symptoms causing significant distress and impairment.

savdaddy  I think part of it stems from the fact that this patients symptoms are occurring within the time-frame for adjustment disorder while SSD seems to have a longer timeline. Aside from that I find it difficult to see why SSD wasn't a possible answer. +  
chillqd  To add to that, I inferred that the obsession with checking temp and with the tingling sensation were signs provided to him by the physicians of recurrence. He is anxious over his cancer recurring, and they are more specific than a variety of body complaints +  
hello  In somatic symptom disorder, the motivation is unconscious. I think for the patient in this Q-stem, his motivation is conscious -- he wants to make sure that recurrence of cancer is not going "undetected". +3  
cienfuegos  I also had issues differentiating these two and ultimately went with SSD, but upon further review it seems that a key differentiating feature was the timeline. His somatic symptoms would have had to have been present for at least 6 months per the DSM criteria +
