Is it Crohn's Disease or Ulcerative Colitis?

I grew tired of all those annoying tables comparing Crohn's Disease (CD) with Ulcerative Colitis (UC). I've boiled these tables down to a few"rules" to look for in the stem of the question.

• 1st rule: If the rectum is spared, it's CD. Or another way to put it is that UC will always start from the rectum and move up, without skip lesions.
• 2nd rule: If there are fistulas, its CD. Remember that CD is transmural.
• 3rd rule: if it involves the small intestine, its NEVER UC. UC will never move past the ileocecal valve, so if there is terminal ileal involvement, it must be CD.
• 4th rule: if there are granulomas, its CD.
  

Hope this helps.

X-linked Recessive disorders
("HE's" get x-linked recessive disorders)
Never answer one of these diseases for a woman! If you are going to answer one of these, you should have an upper motor neuron reflex to look at the stem of the question to make sure its a boy.

Fragile X (self explanatory)
Duchenne Muscular Dystrophy (duc"HE"nne)
Becker Muscular Dystrophy
Hemophilia A (Factor VIII) ("HE"mophilia)
Hemophilia B (Factor IX)
Bruton's Agammaglobulinemia (BOYS get Brutons)
Alport's Syndrome (picture a helicopter at the airport landing. The propeller is shaped like an "X")
G6PD Deficiency (he's get "HE"inz bodies)
Lesch-Nyhan Syndrome
Adrenoleukodystrophy
Fabry Disease (Fabr"HE"s disease)
Hunter's Syndrome (hunters aim at an "X")
Menkes Disease (menk"HE"s, Kinky Hair syndrome, copper problem, don't forget Wilson's disease is also a copper problem)
Rett syndrome (Men, who only have one X chromosome, die before they're born, women have 2 x chromosomes so they can survive to exhibit the disease. This is an exception to the rule that only men are affected by XLR diseases. Thanks Keith)
Wiskott-Aldrich Syndrome (triad of eczema, low platelets, and immune deficiency. Don't forget that eczema is a fancy word for an itchy rash.)

M's the letter for Mycoplasma pneumonia

When you think of mycoplasma, first don't get it confused with mycobacterium!

Then think of the M's

Mycoplasma

IgM (this causes the infamous cold agglutination which can lead to hemolytic anemia)
Bullous Myringitis (bullae on the tympanic membrane)
