This week’s episode of House was definitely a character episode focusing on Dr. Hadley (Dr. Thirteen, that is), and it showed in the jumbled mess that was made of the medicine.

Dr. Thirteen picked up Spencer, a girl at a local bar, and brought her back to her apartment for a night of casual sex. As she is washing up afterward, she looks up to see her companion fall off the bed in a tonic clonic seizure. Spencer is rushed to the hospital (Princeton Plainsboro, of course), and admitted to House’s team.
This is Spencer’s first seizure, but her medical history is also significant for several months of severe fatigue as well as a retinal vein occlusion (a blockage in one of the veins of the eye — very unusual in someone of her age) that happened several years ago. The initial differential includes dehydration, drug abuse, some vague neurological problem, or a blood problem. Kutner and Taub suspects blood clots, which they blame on her bone marrow being in “overdrive” and producing too many platelets. Instead of going about it the easy way and checking a blood count — which includes a platelet count — House orders a bone marrow biopsy. Thirteen performs the biopsy, an extremely painful procedure, but the results are normal.
Later as Spencer is being discharged, she starts gasping and the heart monitor shows tachycardia (a rapid heart rate), which ultimately needs defibrillation to control. Drug abuse is the top potential diagnosis again, and House and Foreman search Thirteen’s apartment looking for clues. They find a brown recluse spider, so a spider bite is now a possibility as well. House orders Thirteen to perform a thorough search of Spencer for a spider bite. She finds no bite, but discovers that Spencer has numbness in the skin over her hip. Labs reveal hypokalemia (a low potassium level), which Thirteen believes explains the numbness and heart problem. House tells her that the low potassium indicates a kidney disease. IgA Nephropathy, PSAGN (post sterptococcal acute glomerulonephritis, i.e. kidney damage following a Strep infection), and Renal Tubular Acidosis (RTA) are all suggested, but RTA is the only one House thinks fits (RTA occurs when the kidney don’t acidify the urine like they should and acid builds up elsewhere in the body. There are several types; House is referring to Type I, or distal, RTA). He orders a CT of the kidneys to look for kidney calcifications, a sign of Type I RTA.
The CT must have been positive, because when we next see Spencer, she is in surgery having kidney calcifications removed. As the operation is ending, her oxygen saturation (the percentage of red blood cells in the arteries that are loaded with oxygen) starts to drop precipitously and she requires intubation. A chest x-ray shows normal lungs so the team suspects she suffered some sort of airway collapse, possibly from an autoimmune disease or some form of dystrophy. House has them place her on a treadmill and perform a methacholine challenge (a medication that causes airway narrowing; used to diagnose asthma) to see if they can induce the airway collapse again so they can diagnose it. Meanwhile, Thirteen is re-examining the x-rays and sees some subtle signs of a flattened diaphragm (a sign that the lung in question in over-inflated), which she interprets to indicate a lung cyst. She rushes to catch up with the rest of the team because she believes placing Spencer on a treadmill will cause her lungs to “explode.”
Thirteen was correct. When she arrives, Spencer is on the ground grasping for breath. Thirteen notes the deviated trachea and realizes Spencer has a tension pneumothorax (from a ruptured lung cyst) and performs a needle thoracostomy to correct the problem. The team obtains a chest CT which shows many other lung cysts. The differential now consists of amyloidosis and pulmonary fibrosis. A cyst is biopsied and shows smooth muscle cells. This is a sign of LAM (lymphangioleiomyomatosis), a progressive and fatal lung disease. When Thirteen breaks the news to Spencer, she notices Spencer is bleeding. A blood count is completely low, which doesn’t fit with LAM. The differential now shifts to include aplastic anemia (the bone marrow stops producing any blood cells), PNH (paroxysmal nocturnal hemoglobinuria), Langerhans Cell Histiocytosis, or mastocytosis. House wants to perform a bone marrow transplant, without killing off Spencer’s own bone marrow first — a definite initiation for graft versus host disease. During a conversation with Thirteen after she gets the consent, he has his weekly “Eureka” moment. Seeing Thirteen chapped lips, he realized that Spencer also has chapped lips; he then realizes that Spencer has never cried, even when told she was going to die, and even when he purposefully exposes her to freshly cut onions. Malfunctioning tear ducts are one of the classic signs of Sjogren’s Syndrome, a type of autoimmune disease. With treatment, Spencer will recover.
Major complaints are in red, minor in blue, nit-picking in green:
While Sjogren’s can be associated with lung cysts, that does not explain away the lung biopsy showing smooth muscle proliferation.
It’s sad when a team of alleged medical geniuses can’t diagnose a tension pneumothorax.
On the other hand, if the pneumothorax is severe enough to cause tracheal deviation and pulmonary collapse, why are there breath sounds? (But then Taub’s a plastic surgeon, maybe he forgot how to use a stethoscope).
What explains the seizure that started the whole episode?
Going straight to bone marrow biopsy is a bad idea. And then forgetting it was normal when discussing all the bone-marrow-influencing diseases later in the episode (aplastic anemia, PNH, etc).
Bone marrow transplant? That came out of nowhere with no supporting diagnosis to explain it, especially the way he wants it done. Remember, her bone marrow biopsy was completely normal at the beginning of the hour.
Kutner and Taub’s “blood clots” diagnosis doesn’t explain anything, except maybe the retinal vein occlusion.
Recent studies show LAM is not as rapidly fatal as initially believed, with many patients living 20+ years after diagnosis.
All that kissing and Thirteen never noticed that Spencer had a severely dry mouth (and would be dry in other significant areas as well).
Brown Recluse Spider bites are hard to miss.
Lung cysts usually show up on x-rays
If Thirteen were properly using a spacer with her steroid inhaler, she wouldn’t have the chapped lips.
The medical mystery was pedestrian (at least by House’s standards), so earns a C-. The final solution of the Sjogren’s is something they should have caught sooner, and contradicts some of the early data. It leaves some important findings unexplained as well. I give it another C-. The medicine was disorganized and all over the place and skipped straight to the zebras, skipping the more common diagnoses and proper tests. It earns a measly D. The non-medical soap opera aspects of this story were good if a little predictable (who couldn’t see that Wilson was stringing House along) and earns a B+.
