A solid episode of House this week with a satisfying twist in the diagnosis at the end. Still, there were several large holes in the medicine. And a new doctor on the team — a psychiatrist.

Margaret is a 30 year-old woman, watching television at home alone, when she hears a suspicious noise. She gets up and finds the front door unlocked and open. She starts carefully creeping through the house, trying to figure out if something is amiss. She calls her husband and he tells her that he’s almost home, but if she’s really concerned, to head to the neighbors. She hears a slamming door and, panicked, runs to the front room — only to discover that it was her husband coming home. There’s no time for reassurance, however, as she immediately started uncontrollably vomiting and develops severe abdominal pain.
Margaret is admitted to the hospital for evaluation of her abdominal pain and vomiting. Prior to admission, she had several days of milder abdominal pain, but no vomiting. She also has slightly elevated LFTs (liver function tests). Before the team can really get started on suggesting possible diagnoses, Chase introduces the doctor he just hired to replace Thirteen: Dr. Kelly Benedict, a very attractive psychiatrist. Once introductions are made, the grilling of Dr. Benedict begins (or “pimping” as it is known in medical school) and it is clear that she is out of her depth. Her suggestions of hepatitis A and appendicitis are quickly discredited, and the team concentrates on the possible diagnoses of lead poisoning and hepatic fibrosis. A liver angiogram is ordered to look for fibrosis, and Foreman and Taub head off to search her house for lead.
The angiogram shows no fibrosis, but it does reveal a narrowing in part of the liver, apparently from old scar tissues. Old broken ribs are also seen on the study. The investigation of Margaret’s house turns up no lead, but it does show that she was in Trenton, and not where she said she was, the day the symptoms started. She tells the team she merely got confused about the dates and it was not an intentional error. She also tells them she broke her ribs back in college when she crashed while cycling.
A short time later, Margaret develops supraventricular tachycardia (an abnormally fast heart rate originating in the top half of the heart). None of the usual tricks (carotid massage, adenosine) work, so she is placed on a pacemaker. Meanwhile, the team calls around for her old medical records, but nothing turns up. Benedict takes it a step further and learns that Margaret didn’t exist until three years ago and she is using the social security number of an elderly lady. When confronted, Margaret tells the team (and her husband) that she was married before and was an abused wife. Her ex-husband beat her and gave her the broken ribs. She moved out, but he found where she was living and poisoned her dog, so she finally got a new identity and moved away. She tells them that her real name is Jenny and that she goes to Trenton for a support group for abused spouses.
Focusing on the heart and stomach symptoms, Benedict is pimped for more possible diagnoses by House and Foreman. Her suggestions of gastritis, atrial fibrillation, cystitis (bladder infection), and cholecystitis (gallbladder disease) are quickly discredited and even mocked (as they should be; those are horrible suggestions). House suggests that Jenny may have been poisoned by her ex, since he did it before and the front door was open. She is started on pralidoxime, an antidote for organophosphate (pesticide) poisoning. The treatment doesn’t work, and she develops a fever (”pyrexia”) of 103. She is placed under a cooling blanket. Endocarditis is suggested and discarded before the team elects to treat possible Legionnaire’s disease.
Jenny’s husband mentions that he called the hospital in Trenton and there is no support group for abuse victims. He wonders what else she may have been lying about. When he tries to talk to her, she starts to hallucinate — mostly worms, snakes, and fire — and starts screaming. Radiology of the brain is obtained and shows a possible lesion. The team believes this to be the cause of her hallucinations and their differential diagnosis is abscess, lymphoma, or Wegener’s disease. Dr. Benedict disagrees and thinks the brain lesion is just a coincidence; she believes Jenny is actually suffering from a mental illness — she suspects bipolar disease. The physical symptoms are from some other, yet to be diagnosed, condition. House disagrees, and has the team prep Jenny ready for a brain biopsy. Just as Chase is starting to drill into the skull, Taub points out that Jenny is no longer febrile — one of her symptoms has stopped. Questioning Dr. Benedict closely, it turns out that she had been slowly turning down the cooling blanket, so Jenny has actually been afebrile (no fever) for some time. Could the fever have just been an antibiotic reaction? (Quick answer: no, Jenny was started on antibiotics after the fever. In fact, that’s the symptom that prompted their use). At this point, it finally dawns on the team that she has not vomited since her arrival. That’s another symptom resolved. House stops her pacemaker and nothing happens — her heart rate remains normal. That was her last major physical symptom, resolved as well. Benedict suggests that Jenny’s mental symptoms — the hallucinations — may have just been caused by a stress reaction to her physical symptoms, but House realizes it is just the opposite. Her mental symptoms were primary, and the physical symptoms are all secondary. He starts her on haloperidol (Haldol, an antipsychotic) and lorazepam (Ativan, an anti-anxiety agent) and tells the team to call him when she wakes up from anesthesia. It turns out that Jenny is a long time schizophrenic. She had been secretly seeing a psychiatrist in Trenton (hence her frequent visits) and had been taking risperidone to control the schizophrenia. Unfortunately, she started to develop side effects (abdominal pain, initially) to the medication so her doctor started to wean her off the medication -– which was then stopped abruptly when she was admitted to the hospital. Her physical symptoms were all risperidone induced and her hallucinations were the schizophrenia returning.
As usual, major complaints are in red, minor complaints are in blue, and nit-picking ones in green:
So Jenny’s side effects from the risperidol worsened when the medication was stopped? She didn’t develop the fever and tachycardia until she had been off the medication for some time.
Vagal maneuvers are first line for SVT (i.e. do them before injecting adenosine). When those don’t work, then you try adenosine, several doses if needed. If that doesn’t work, then you go for cardioversion (i.e shock). Pacemakers have no role in the treatment of acute SVT.
Sorry to correct the psychiatrist, Jenny was suffering from hallucinations more than delusions.
And she has an unexplained lesion in her temporal lobe.
Angiogrophy is not the primary test for diagnosing hepatic fibrosis. It can be helpful in looking at the extent of the disease once it has been diagnosis, but it’s not very good at diagnosis. (Ultrasound, CT, or MRI are better choices, but a liver biopsy is really the gold standard for diagnosing hepatic fibrosis).
Maybe Jenny hadn’t vomited because, like most patients with nausea and vomiting, she was on strong anti-nausea medications.
While pralidoxime is used for the treatment of organophosphate poisoning, atropine is also required (in fact, recent studies suggest atropine is the key component and pralidoxime not so important).
An EKG and lack of Osler’s nodes are not good reasons for ruling out endocarditis (Osler nodes, for instance, only occur in 10-25% of endocarditis patients). Echocardiogram is better, but even at best it’s only about 90% correct. You need lots of bloodwork, especially blood cultures, to truly rule out endocarditis.
I like how House slams a patient with a major tranquilizer (haloperidol) and a minor tranquilizer (lorazepam) and expects her to wake up (even in a few hours) and be intelligible. Not going to happen.
So the whole “they’re calling from inside the house!” opening was just a red herring and had nothing to do with the diagnosis at all. So she just left the doors open?
And she has an unexplained lesion in her temporal lobe.
This was yet another good medical mystery, even though the symptoms were very common — common enough to make we wonder why she ended up on House’s service. Still, I give it a solid B. The final solution was clever and, if one ignores the timecourse, fits. I give in a B-. The medicine was about average. For the second week, the progression was fairly logical, though points are deducted for some relatively obvious errors (antibiotics/fever, SVT treatment). I give it a B-. The soap opera was still good. I liked the new doctor — even though she clearly wasn’t cut out for House’s team — but need to see more Wilson. I given it a B.
