Another thing I have to tell patients and their families at least a couple of time per week.

Hank, a successful porn star is admitted to Princeton Plainsboro Teaching Hospital after developing a severe headache and photophobia (sensitivity to light) while on set. House starts off by ordering a series of tests: an STD panel (to look for sexually transmitted diseases), a toxin screen (to look for common toxins), C-Reactive Protein (”CRP”, a measure of inflammation), ANA (antinuclear antibodies, to look for autoimmune diseases) and a lumbar puncture (to look for viral encephalitis). While the patient is having his spinal tap performed, he develops severe muscle spam and pain (tetany) in his arms. Foreman orders meperidine (Demerol, a strong pain medication).

About this time, House starts hitting up Taub and Thirteen for ideas, trying to lure them back on the team. Taub suggests that Hank must have a brain problem, such as a tumor or seizure. Foreman believes that Hank suffers from cerebral vasculitis (inflammation of the blood vessels in the brain). House agrees with Foreman’s assessment and starts the patient on steroids. He also orders a brain angiogram (an x-ray of the arteries in the brain), as well as an EEG and a nerve biopsy, just to be sure. Foreman convinces Chase to perform the angiogram, but he and Cameron suspect that the patient is suffering from Vitamin D deficiency, so instead of checking the angiogram, they decide to start Hank on light therapy and intravenous vitamin replacement. Unfortunately, while undergoing the light therapy, Hank develops a nosebleed and is found to have petechiae on his legs.

Hank is now diagnosed with disseminated intravascular coagulation (DIC, a weird, but very serious, condition, where the patient is both bleeding too much and clotting too much). Sepsis is suggested as a possible cause, but since he is showing none of the shock associated with sepsis, the idea is discarded. Bacteremia (bacteria in the blood) is suggested, but Cameron shoots it down suggesting instead Meningococcemia (meningococcal bacteria in the blood — really a subset of what Chase suggested). House concurs with Cameron’s diagnosis and Hank is started on heparin (a blood thinner, for the clots) and a broad spectrum antibiotic that covers meningococcus (but if you know which bacteria you’re treating, then you don’t need a broad spectrum antibiotic).

Hank does not improve and he starts to run a fever. Taub suggests that he might have an infection hidden away in his sinuses, where the antibiotics have difficulty reaching, so Chase performs sinus surgery to clear out the sinuses. Now Hank begins to complain of severe abdominal pain and Cameron discovers something on the exam (apparent ascites — fluid in the abdomen) that makes her diagnose liver failure. She suggests a Klatskin tumor (cancer of the bile duct), but it doesn’t quite fit the symptoms. Foreman suggests that Hank has sclerosing cholangitis (a disease that damages the bile ducts). House agrees and an ERCP (an endoscopic exam of the bile duct and pancreas) is ordered — surprisingly it shows a mass in the common bile duct that ends up being a large clump of worms. Hank apparently has strongyloides (”whipworm threadworm”), and is given mebendazole to kill the worms.

Once again, Hank’s condition dramatically worsens. He develops severe pulmonary edema (fluid build up in the lungs). Chase thinks it might be a combination of a hematological (blood) problem and cardiomyopathy (a heart problem). Foremen suspects Hank has lymphoma, with peritoneal carcinomatosis (malignant spread of cancer across the abdomen) and paraneoplastic syndrome explaining his symptoms. House sides with Foreman, and Hank is started on chemotherapy. A short time later, Hank’s condition takes another turn for the worse when he starts urinating blood. Next, his blood pressure and heart rate skyrocket, and he starts to bleed from his mouth. He then suffers a cardiac arrest, but the team is able to stabilize him.

The latest labs are back and show that Hank barely has any red blood cells, white blood cells, or platelets. The differential diagnosis now includes hypopituitarism (an underfunctioning pituitary gland), renal cell carcinoma (a type of kidney cancer), or aleukemic leukemia (a leukemia that is associated with low white blood counts instead of the normally high counts found in leukemia). House tells the team that the latter is the most likely and orders them to ablate (destroy) Hank’s bone marrow in anticipation of a bone marrow transplant. There is a lot of hemming and hawing about whether this is the right thing to do, since it could make Hank sicker or kill him, but at the last moment, Thirteen and Taub call in with the correct diagnosis: extraintestinal Crohn’s disease. According to them, Hank’s exceptionally clean childhood made him more likely to develop diseases such as Crohn’s, and the worms were actually helping him keep the disease in check. Once the worms were killed off, the Crohn’s flared up with a vengeance. With some methylprednisolone (steroids), Hank should get better — but the team wants to give him some worms again, just to make sure.

I found no massive errors in tonight’s episode. There was the usual: jumping randomly between unrelated diagnoses, bizarre test interpretation, and Chase being a specialist surgeon, but nothing horrible. Of course, that’s not to say I have no complaints (as if!). As usual, minor complaints are in blue, nit-picking ones in green:

Where exactly was the extraintestinal focus of the Crohn’s?

Why did he develop a headache and photophobia in the beginning? Was that the Crohn’s? Why did everything suddenly worsen when he got in the hospital? The steroids he was given for the vasculitis should have calmed down the Crohn’s.

The strongyloides worms may not have been the cause of his disease, but their blockage of the bile duct would still cause serious problems for the patient.

Again, no oncologist is going to start chemotherapy for cancer without a tissue diagnosis.

Special precautions are taken for patients who are neutropenic (dangerously low in white blood cells, and thus more susceptible to infection) including gowning and gloving everybody in contact with the patient. You do not roll them down the hospital’s common hallway without a mask and with the wife holding his hand.

The CRP should have been significantly elevated with the Crohn’s disease (and the cerebral vasculitis too).

While the ANA is generally strongly positive for certain types of autoimmune diseases, it is not found in every autoimmune condition (or even most autoimmune conditions), so a negative ANA does not mean there is no autoimmune disease (and positive ANAs in the absence of autoimmune pathology are also possible).

How about checking the vitamin D level — an easy thing to do — before treating the patient.

I noticed how they avoided actually saying the word “ascites” and instead chose a wordier explanation. Probably because of their problem pronouncing it last time.

Cameron shoots down Chase’s idea of bacteremia, but then suggests meningococcemia, a type of bacteremia. The same argument she used against Chase would go against her as well.

Why would you ablate the bone marrow without finding a donor first? (OK, maybe House was never planning on really following through with it, but why would the others go along?)

And now credit where credit is due:
The hygiene hypothesis is a legitimate and controversial scientific theory concerning the rise in asthma and allergy rates in industrialized nations. Some researchers link it to autoimmune diseases as well.
Helminthic therapy — treatment of disease using intentional infestation of parasitic worms — is being tested in a variety of diseases, including Crohn’s/
Shocking ventricular tachycardia, like Foreman did this episode, is the right treatment.

The mystery was okay, but seemed to get lost in the shuffle as the show progressed. I give it a B. The final solution was a stretch, especially when you look back at the original symptoms. It earns a C. Overall, the medicine was better that it has been the past few weeks and earns another B. The soap opera was decent as well. I enjoy Tab and Thirteen, so I’m fine with having them back, though I know many will disagree. The soap opera earns still another B.

The Plot:The Observer is patiently standing in front of a museum in Boston, taking notes, and spying on brunettes. After a few minutes, he finds the one he wants, grabs her, throws her in the back of a stolen car and drives off. Arriving at an out of town motel, he gags her and ties her to a chair, and then leaves.

With the Observer involved, the Fringe team is called in. The kidnap victim is identified as Christine Hollis, and seems to be an entirely normal young woman. They review the surveillance camera footage and realize that this is a different Observer than the one they first met. It turns out that the Observer accidentally left his notebook behind, so it’s turned over to the team; however, they are unable to decipher the code/language in the book. Astrid identifies over 1200 different symbols, without any repeats. Looking online, she discovers that one of the researchers at Massive Dynamics is also interested in the code. He has not been able to solve it either, but he has documented evidence of Observers at important historical events including the Boston Massacre, the beheading of Marie Antoinette, and the shooting of Archduke Ferdinand. Peter finds a drop of what appears to be blood in the Observer’s journal. Walter notes its orange cast and wonders if the Observer might not have hemophilia.

At a restaurant across town, a group of three Observers are meeting to discuss the actions of the rogue Observer, whom they call “August”. They mention a plane flight and imply that Christine is supposed to be dead, so they send an assassin after her.

August returns to the hotel room, unties Christine, and shows her the television news, which reports that the flight she had booked to Rome crashed en route with no survivors.

The labs tests come back and the drop in the journal wasn’t blood, but hot pepper sauce — and sauce from a particular hot pepper: the King Cobra Chili. Astrid is able to find the address of the individual who imported some last year, so Olivia and Peter head over to check it out. As luck would have it, the Observers’ assassin is there at the same time. There are some fisticuffs and Peter sustains a small wound, but the assassin escapes.

August meets with the other Observers. They tell him that Christine must be killed to set things right. This is not what he wants to hear. He manages to set up a meeting with Walter, asking for his help. All Walter can tell him is that he must somehow make Christine important to the Observers, so they won’t kill her.

August returns to the hotel room and unties Christine. He tells her that she must do exactly as he says. A short time later, the assassin appears at the hotel and in the ensuing battle, August is shot and critically wounded. Olivia and Peter arrive, and August gives his gun to Peter. Together, Peter and Olivia are able to kill the assassin. They find Christine and return her home.

The first Observer picks up August and drives him away from the hotel. As August lies dying in the back, he tells the other Observer that he had developed “feelings” for Christine, even loved her — and that is why he saved her. The first Observer tells August that she is safe now because she is responsible for the death of an Observer, and that makes her important.

1. Hot, Hot, Hot
The King Cobra Chile is the hottest chile known to man, scoring 850,000 to 1,000,000 Scoville units. It is also known as the “ghost chile”, which should be familiar to you if you watch Man v. Food.

2. 15% Tip
Why would it be a surprise that the tip about August was called in from the same hotel? Would it really be a shock that one of the other guests, or an employee, saw him and phoned it in?

3. Color of Love
This is the first I’ve ever heard of hemophiliacs having orange blood, and I don’t buy it. Hemophilia affects the clotting of the blood, not the hemoglobin (which is what gives blood its red color), so why would the blood be a different color?

4. You Go That Way, I’ll Go This Way
I would not want to be Olivia’s insurance agent, and I hate for her to be my backup. Tonight she: 1) was easily distracted by the assassin, 2) nearly shot Peter, and 3) only avoided being shot by the assassin due to dumb luck and Peter.

A much better episode this week. The show does much better when they stick with the Pattern. There is a one-minute improvement on the Doomsday Clock.

I just finished reading The Last Days of Animal Man, and I’ve got a couple of problems with it, particularly the last issue.

1.
Animal Man defeats the villains by using his powers to infect them with Yersinia pestis, the Bubonic Plague. At first read, this is extremely clever — in a Merlin versus Madame Mim sort of way. But the more you think about it, the less sense it actually makes.

Animal Man’s powers allow him to gain the abilities of any animals he is near. He can gain the strength of a gorilla, the flight of a bird, the swimming ability of a fish, and so on. In this case, it appears he used his powers to gain the virulence of the bacteria.

Animal Man doesn’t become the animal in question; he just gains some of their abilities. So if he had won by incapacitating his opponents with a nasty bacterial toxin, that would make a certain amount of sense. But instead he actually infected them with the bacteria. How did he manage this? His powers don’t work this way. You need the actual bacteria to cause an infection, let alone one which is “overwhelming their immune systems.” Animal Man wasn’t infected himself, and he didn’t come into contact with the bacteria, so how did he infect the villains? He seems to have achieved abiogenesis – creating life (in this case the bacteria) from nothing.

2.
The biggest problem is basic biology. It goes back to something I first learned in seventh-grade science. Everyone read what Superman says, and then repeat after me: bacteria are not animals.

They belong to a separate kingdom entirely.

I’m not going to explain what’s wrong with this caption from The Last Days of Animal Man #6 — I’ll leave it to you.

James Sidas was a brilliant physics prodigy who quit the field twelve years ago and now works as a deliveryman. While he is delivering some books one day, he develops a hand tremor and some confusion. He is admitted to House’s team at Princeton-Plainsboro Hospital, with the presenting complaints of ataxia (loss of coordination), anemia, and a mild cough. A CT scan was negative, as was a screen for toxin screen. The team’s initial differential diagnosis consists of West Nile Virus, hyperbilirubinemia (high bilirubin levels in the blood), meningitis, sickle cell anemia, or TTP (thrombotic thrombocytopenic purpura). The last one seems the most likely so House has his team check a blood smear and AdamTS13 antibodies. The blood smear shows schistocytes (fragmented red blood cells), a sign of TTP, so they decide to begin treatment. Usually, plasmapheresis is treatment of choice, but James is allergic to one of the components of the procedure, so instead they perform a splenectomy — a removal of his spleen. The surgery goes well, but while Chase is examining him afterward, James begins to show symptoms of a stroke. He is rushed to the cath lab, where the clot in the brain is removed by a special catheter, “blood flow is restored,” and there is no permanent brain damage.

The fact that James suffered a stroke after his spleen was removed suggests that he did not have TTP. The differential now consists of CNS vasculitis (inflammation of the blood vessels in the brain), DIC (disseminated intravascular coagulation), acquired pancytopenia (low white cells, red cells, and platelets), or a toxin exposure. The team reasons that the basic toxin screen only tests for a few toxins, and they need to test for more. Chase and Taub are sent to search James’s apartment, while Thirteen and Foreman run an expanded toxicity screen. The apartment shows signs of mice (and Taub suggests James may have Leptospirosis), and a hidden bottle of booze.

The team now suspects that James has liver failure, probably due to alcohol abuse. When confronted, James admits to having a shot of vodka each day after work, but denies being an alcoholic. The team proceeds with a liver biopsy, which is normal. The liver function tests show a slightly elevated albumin, but are otherwise normal. Thirteen now deduces that James has renal (kidney) failure, not liver failure. The reasons for the kidney failure could be rhabdomyolysis (muscle damage), multiple myeloma (cancer of the blood forming cells), polycystic kidney disease, or Goodpasture’s Syndrome (an autoimmune disease that affects the kidneys and lungs). Goodpasture’s seems the most likely, so James is started on unnamed “immunosuppresant drugs” and dialysis. After a Eureka! moment in a conversation with Wilson, House realizes that James has been abusing dextrome
