Pemphigus vulgaris & Bullous pemphigoid are autoimmune diseases of the skin.
Here's a strange association I've made in my head to help me remember most of the points about Pemphigus vulgaris.. And then, I remember that the other one is the other one =D
*talking to myself* I have to learn about surgical instruments for my practical exams. It's BORING. Especially, when I know that I might never even get the chance to use them :\ Let's draw them!! And write funny and cool descriptions about them!!
Hola!
We'll be learning about the Wernicke's area and Broca's areas of the cerebral cortex!
Let's get started <3
What is Broca's area?
It is the motor speech area. Motor? Yeah, it helps in movements required to produce speech.
What is Wernicke's area?
It is the sensory speech area. Sensory? Yes, it helps you understand speech.
It also helps in usage of correct words to express our thoughts.
What is chronic atrophic gastritis?
It is a process of chronic inflammation of the gastric mucosa. What are the causes of chronic atrophic gastritis?
It can be caused by persistent infection with Helicobacter pylori, or can be autoimmune in origin.
What are Darrow Yannet diagrams?
They are graphs that tell you the osmolarity and volume changes of body fluids.
X axis represents volume.
Y axis represents solute concentration.
Total body water = 2/3 ICF (Intracellular fluid) + 1/3 ECF (Extracellular fluid)
Remember:
All volume disturbances originate in the ECF compartment.
Changes in ICF are in response to changes in ECF.
How to make the graph in your head -
Step 1. Figure out what happens to the osmolarity and volume in the ECF compartment (ECF is the smaller compartment)
Step 2. Think how is ICF affected? Let's review some examples to make sure we understand the concept!
What is prerenal failure?
Prerenal acute renal failure (ARF) occurs when a sudden reduction in blood flow to the kidney (renal hypoperfusion) causes a loss of kidney function.
In prerenal acute renal failure, there is nothing wrong with the kidney itself.
What is acute tubular necrosis?
Acute tubular necrosis is a kidney disorder involving damage to the tubule cells of the kidneys, which can lead to acute kidney failure.
What is the difference between prerenal failure & acute tubular necrosis?
