Despite the barely above average medicine, I enjoyed this episode of House. Probably because it focused more on House himself than on Foreteen.

Jackson is a teenager born with genetic mosaicism whose parents have chosen to raise him as a male. He is playing on the school’s basketball team and he has just made the winning basket when he collapses to the ground with severe abdominal pain. He is later admitted to House’s service for treatment of this “chronic pelvic pain”. An issue is that his parents have never told him about his underlying genetic condition and have been giving him testosterone shots under the fiction that they are vitamins. They don’t want House or his team to tell him the truth, a situation that doesn’t sit well with some of the team, particularly Thirteen.
The team’s initial differential includes dehydration, congenital adrenal hyperplasia, PMDS (Persistent Mullerian Duct Syndrome), a blind uterus, or problems from the surgical reconstruction of his penis. House wants to perform a urethroscopy, but the parents want an MRI to look for a blind uterus. House gives into their suggestion and an MRI is ordered. The results are negative, so Jackson is prepared for the urethroscopy. As they start the procedure he starts to complain of chest pain and shortness of breath. Thirteen only hears muffled heart sounds on exam and notices jugular venous distention. He appears to be in cardiac tamponade so she jabs a syringe blindly into his chest to remove the extra fluid from around the heart.
The team’s second attempt at a differential diagnosis only yields the generalities of “drugs, toxins or infection.” Then autoimmune disease related to the testosterone injections is mentioned, especially polyarteritis or SLE (lupus). House has the team start Jackson on corticosteroids for the suspected autoimmune condition and finasteride to block the effects of the testosterone. (It’s not made clear at this point, but the testosterone injections are stopped as well). As Thirteen is administering the medicine, she notices red palms on Jackson. She takes this to mean that 1) he has does not have an autoimmune disease, and 2) his liver and kidneys are failing. Blood tests back this up (her second point, at least).
The third version of a differential diagnosis contains amyloidosis or drug/alcohol abuse due to depression. A search of his room yields some dismal and morbid poetry that Thirteen takes as proof that Jackson is depressed. She feels this depression is related to his sexual identity issues and wants his parents to tell him the truth, but his mother refuses. Meanwhile, Taub finds evidence of toxoplasmosis on Jackson’s water bottle, so infection is a possibility as well. He is started on pyrimethamine to treat the suspected toxoplasmosis. His parents ask that his testosterone be restarted as well. When Thirteen is injecting the medicine into Jackson, she confesses that it isn’t a vitamin shot like he’d been told — though she doesn’t tell him what it is, just tells him to ask his parents. This triggers a showdown with her and the parents in Cuddy’s office. Cuddy backs Thirteen, but lets her know it is for Jackson’s sake, not her own. When told the truth, Jackson understandably becomes angry and refuses to speak with his parents anymore. Thirteen comes back in to talk with him and lets him know about finding the poem. He tells her it was for a class assignment (”write a poem in the style of Sylvia Plath”), and was not about his feeling at all. He tells her that he doesn’t feel depressed — or at least he didn’t until his parents told him the truth about his genetics. He becomes suddenly nauseated and begins to vomit blood.
Jackson is found to have a gastric fistula due to necrotizing pancreatitis. Thirteen suggests Zollinger-Ellison Syndrome, but Taub believes it is systemic scleroderma. Foreman decides to treat the possible Zollinger-Ellison first and if that doesn’t work, then to treat the scleroderma. He and the rest of the team know that sclerodema is more likely, but also has a worse outcome, so they are treating the Zollinger Ellison and hoping for the best. It doesn’t work, so Jackson is started on anti-inflammatory medication to treat the scleroderma. The next morning, Foreman tells Thirteen that it is having some effect as Jackson’s liver enzymes are improving. Through some convoluted logic, they deduce that this means it cannot be sclerodema since he is getting better too fast. About this time, House reappears on the scene, hears about the case and instantly makes the diagnosis: it all started with dehydration; that’s what caused the collapse. The ER gave him some IV fluids, but because of his use if energy drinks (which apparently also caused his abdominal pain), his kidneys were slow to respond. When Jackson was then given the contrast for the MRI, the already dehydration/energy drink-strained kidneys could not filter the contrast fast enough so it cycled throughout the body, causing problems wherever it went. It was this contrast that caused the heart disease, the liver failure, the kidney failure, and the pancreatitis.
Methadone is a potent narcotic, and has more respiratory depression than more common narcotics, but it’s not that life threatening. Particularly in a patient with such a heavy previous use of narcotics.
I did like House’s realization that he can’t be the brilliant diagnostician he wants to be if he’s not in pain.
Mosaicism occurs when one person has two genetically distinct lines of cells. Some of their cells have one set of genes, and the other cells have a different set. Mosaicism generally occurs early in development, often from a mutation or nondisjunction. In Jackson’s case, one cell line is genotypically male (XY) and the other female (XX). This is a known, but rare, cause of intersexuality.
As usual, minor complaints are in blue, and nit-picking in green. My main complaint this week, the red one, I’d characterize as a “moderate” complaints — more than minor, but less than major. It’s theoretically possible, but extremely unlikely.
Intravenous contrast can certainly cause renal problems, my kidneys are proof of that. Contrast material can cause acute renal failure (contrast-induced nephropathy). There have also been isolated cases of pancreatitis and pericardial effusion thought to be linked to contrast material, but the patients involved all had significant other co-morbidities (such as AIDS). For Jackson to have had such problems with contrast, his kidneys must have been in bad shape, which should have shown up on simple blood tests — blood tests which radiologists are maniacal about ordering and avoiding the use of contrast if they looks even a little off.
I guess this sort of complication is what happens when you act as your own radiologist.
And seriously, how many energy drinks was this kid downing to cause these problems?
Notice how vague the writers were being when treating the scleroderma: repeatedly using the term “anti-inflammatories” instead of naming a specific drug. This is usually a sign that they’re trying to skirt around a known plot inconsistency.
Such as the fact the anti-inflammatory that they’d use would likely be a corticosteroid, the same type of drug they gave Jackson for a suspected autoimmune condition in the first half of the show. In fact, scleroderma is an autoimmune condition.
I like how psychic the team can be. Thirteen automatically knows it’s an exudate causing Jackson’s tamponade instead of the more common (and seen just two episodes ago) blood.
That’s incredibly fast for an exudate to form.
Blindly jamming a needle in the chest is still not a good idea. It wouldn’t take that much longer the properly position it, and just a little more time to attach it to a cardiac monitor.
Finasteride is not approved for use in children. It blocks the breakdown of testosterone into dihydrotestosterone (DHT), which I guess might help if it is the DHT causing the lupus reaction and not the testosterone itself. Otherwise, you’ve just made things worse by increasing the levels of testosterone.
Toxoplasmosis is a common parasitic disease, but does not typically cause problems in people with healthy immune systems. It is a worry in patients with compromised immune systems and in pregnant patients, because it is one of the diseases that can be passed from mother to fetus.
Symptoms don’t match at all.
Pyrimethamine is not used alone to treat toxoplasmosis. It is given with a sulfonamide.
I suspect a pelvic U/S would be a better choice than MRI when looking for a blind uterus, but then you’d avoid that whole contrast material concept.
Several hours of pelvic pain is not chronic.
The medical mystery was good. The mosaicism was a red herring in terms of the mystery itself — though it did add to the family dynamics issues. I give the mystery a B+. The final diagnosis was logical, but would have required a perfect storm of events to occur. I give it a B. The medicine overall remained haphazard, but at least it was more focused than previous weeks (except for the toxoplasmosis, that came out of left field), and earns a C+. The soap opera was fairly good, both the “House is happy” and “Mother avoids the issue” aspects. I give it a B.
