A Monday episode of House brings us a young model and an interesting diagnosis. By the way, this medical review contains a few spoilers, so don’t say I didn’t warn you…

Alex, a 15 year old super-model, complains of feeling nauseous and is profusely sweating. Her father gives her a Valium and a drink of his champagne to calm her down. She heads on down the catwalk but stumbles. She experiences double vision and punches another model who tries to help. Finally, she collapses on the runway.
Alex is admitted to the hospital for evaluation of her collapse (though she describes it as more of a cataplectic attack). She admits to feeling sweaty and nauseous for a while. A history also reveals that she has yet to start menstruating. Lab tests are drawn and all are normal except for drug screen which comes back positive for “Valium” and “heroin.” The Valium can be explained by the pill her father gave her, but the heroin suggests to the team that she is suffering heroin withdrawal (I should point out that these tests are not that specific, so would have come up “benzodiazepine positive” and “opiate positive”, without identifying the specific drugs. For all we know, Alex could have been taking Xanax on her own in addition to the Valium her father gave her…)
The differential diagnosis includes heroin withdrawal, juvenile multiple sclerosis, and Parkinson’s syndrome. House suspects most of her symptoms are due to the withdrawal, but he wants her completely free from heroin so he can ensure that just the withdrawal was causing her problems. He decides to pursue a rapid detox. Basically, Alex is placed in a medically-induced coma and fed naltrexone. Naltrexone blocks the opioid receptors and sends the patient into a complete and immediate withdrawal. It is a risky procedure, but a real one and there are centers that specialize in it.
Alex suffers some sort of cardiac arrest during the coma. They refer to it several times as a “heart attack,” but it seemed more a rhythm problem than an actual heart attack (and if it was a heart attack, they did absolutely nothing to treat it or to prevent the next one). After she comes out of the coma, she has a problem with her short term memory, repeating the same questions over and over. The team is concerned that Alex may have suffered brain damage due to oxygen deprivation from her “heart attack.” House isn’t convinced. He feels she wasn’t without oxygen long enough to cause a problem; he suspects Post-Traumatic Stress Disorder (PTSD) because he thinks her father sexually abuses her. He orders an MRI and an LP (lumbar puncture) and he goes to have a chat with her father. The team tries to get an MRI, but Alex develops an uncontrollable muscle twitch so they can’t proceed with the test. They are able to perform a lumbar puncture which shows increased protein in her cerebrospinal fluid.
The doctors are now concerned about that Alex may have any one of a number of brain diseases including viral encephalitis, CMV (cytomegalovirus), and CJD (Creutzfeldt-Jakob Disease). House wants to proceed straight to a brain biopsy (instead of getting a CT scan, or sedating her for an MRI). The brain biopsy shows no white matter disease, so the team now starts to focus on the grey matter. Foreman lists off a whole string of rare neurological diseases and House suggests that it may be paraneoplastic syndrome. Paraneoplastic Syndrome is a rare disease that occurs when a person has cancer and their body attempts to make antibodies against the tumor. These antibodies misfire, and affect the person instead, causing a whole range or symptoms including weakness, memory loss, and problems with coordination.
Alex is given IV immunoglobulin and she stops twitching. This supports the diagnosis of paraneoplastic disease because the immune globulin is thought to block the antibodies causing the problems. She is now subjected to test after test trying to find the tumor House knows must be there. Small ovaries seen on a pelvic ultrasound, but every other test is normal.
House is still convinced there is cancer somewhere. The rest of the team are still thinking it may be PTSD since her father did admit that he had slept with her. House has a burst of insight and gets an MRI of Alex’s pelvic area. He discovers that Alex has “male pseudohermaphrodism” and has testes instead of ovaries. A tumor on one of these testes is what has given Alex her paraneoplastic syndrome and explains away all her symptoms. The tumor can be removed surgically, but what can be done for Alex who thought she was a she but may be a he (depending on how strictly you choose to define the terms). I think the psych consult was a good idea.
The mystery was interesting and the final solution clever. I have only one major complaint about the final diagnosis (or rather, how they missed it), which I’ll get into a little later. The rest of the medicine was not perfect, but at least passable. Well, except for that “heart attack” thing.
The soap opera this week centered on two things: House’s increasing pain in his leg, and the sexual abuse of Alex by her father. As for House, is his pain physical in nature or psychological. He believes it is physical, but Wilson believes — and Cuddy proves — that it is to a large part psychological.
Alex father admits to having had sexual relations with Alex once. When House does not report this immediately to the authorities (which he is legally obligated to do in every state, even New Jersey), Cameron does. When both Alex and her father deny it every happened, there is nothing the social worker can do. Cameron confronts Alex, but Alex surprises her by telling Cameron that she seduced her own father, as well as every other male authority figure in her life, so she could get what she wanted. What is it with this show’s writers and overly manipulative women?
Back to the medical: Male pseudohermaphrodism is an older term that has fallen out of general use because it is a non-specific term, and can describe several different situations. The condition House is describing is Androgen Insensitivity Syndrome, also known as Testicular Feminization Syndrome. In this condition, a male fetus is resistant to the effects of testosterone. It develops testes but proceeds little further in male sexual development. The testes will not descend, and normal female external anatomy develops. The individual in question appears to be a completely normal female, though they tend to enter puberty later than other girls. They never develop a menstrual cycle as there are no ovaries or uterus. I can understand why Wilson may have thought Alex had ovaries on an ultrasound, because that’s what he was looking for, but he should have noticed the complete lack of a uterus. And even if they were testes, the ultrasound still should have picked up the tumor because ultrasound is what we use to find testicular tumors.
This episode gets a
B+ for the mystery and an
A for the solution. The medicine earns a
B, because I marked it down for the “heart attack” and the whole “whoops, I missed the uterus” thing. The soap opera aspects earn a strong
B+.
