    Let's do some questions. The first question. A 30 year old male executive presents to the ER in kidney failure. He is on an unknown over-the-counter anti-inflammatory medication. He has ingested cocaine on an intermittent for the past 5 years. He is obtunded, edematous, and oliguric. His renal function is falling with significant hematuria and casts in the urine. Which of the following is true? A, he was probably taking celecoxib, which can cause renal failure and may interact with the cocaine. B, he may have renal papillary necrosis from the cutting agnet phenacetin in the cocain that he was using. C, he may have taken Aspirin prior to using the cocaine, and developed Reye's syndrome. Or D, the anti-inflammatory he has taken has caused interstitial hemorrhage in his kidney. What's the most likely answer? So he may have renal papillary necrosis from the cutting agent phenacetin in the cocaine that he was using. Now, let's take a look at this question. Celecoxib may exacerbate renal dysfunction but is unlikely to cause the clinical scenario here. A is not correct. B, it's believed that Howard Hughes died as a result of a toxic side effect from phenacetin, resulting in renal papillary necrosis and death. B is the most likely answer. Phenacetin is also linked with hemolytic anemia in patients with G6PD deficiency. This patient may be experiencing hemolytic anemia as well as renal failure, but the clinical picture isn't consistent with that possibility at this time. Reye's syndrome is associated with Aspirin use in children. Now, most NSAIDs can cause an abnormality in clotting fomation, but this scenario is unlikely at this time. Let's go on to question number 2. A 66 year old woman has been placed on methotrexate 7.5 mg once a week. She also has folic acid...
