Learn Common Diseases: 118 Flashcards on Infectious, Autoimmune and Neuropsychiatric Conditions
Learn 118 common diseases with flashcards: infectious (TB, malaria, hepatitis), autoimmune (lupus, MS, Graves') and neuropsychiatric (stroke, depression).
Three organ systems, one exam. Gut, glands and skin sit in different chapters of every textbook, but they turn up together in the same clinical vignettes — the diabetic with gastroparesis, the celiac patient with dermatitis herpetiformis, the Graves case that walks in because of a rash. Learning them as one block is closer to how they are actually tested.

That is what Common Diseases: GI, Endocrine and Dermatological (deck code AY6863, 99 cards) covers on Flip It: definitions tight enough to recall under pressure, and the contrast cards that separate look-alike conditions.
Sample cards
| Front | Back |
|---|---|
| Crohn's disease vs ulcerative colitis | Crohn's can affect any part of the GI tract with patchy inflammation through all layers; UC affects only colon and rectum with continuous superficial inflammation |
| Barrett's esophagus | A complication of chronic GERD where the esophageal lining changes to resemble intestinal tissue, increasing cancer risk |
| Addison's disease | The adrenal glands do not produce enough cortisol and aldosterone |
| Hashimoto's thyroiditis | Autoimmune disorder causing hypothyroidism through chronic inflammation and destruction of the thyroid |
| Diabetic ketoacidosis (DKA) | Excess blood acids (ketones) produced because of a lack of insulin |
| ABCDE rule for melanoma detection | Asymmetry, Border irregularity, Color variation, Diameter over 6 mm, Evolving |
| Five layers of the epidermis | Stratum corneum, lucidum, granulosum, spinosum, basale (outer to inner) |
| Ringworm (tinea) | A fungal infection, not a worm — circular, red, scaly patches on skin, scalp, nails or feet |
| Stevens-Johnson syndrome | Rare, life-threatening reaction, often to medications, with severe skin and mucous membrane blistering |

Two study moves specific to this material
Drill the paired opposites in the same session. This deck is built on symmetric pairs: hypo- versus hyperthyroidism, Graves versus Hashimoto, Cushing versus Addison, hyper- versus hypoparathyroidism, DKA versus HHS, Crohn versus UC. Reviewing one half a day after the other is how people end up with reversed answers. Put each pair back to back and force yourself to state the difference out loud before flipping.
Turn every skin card into a visual. Dermatology is pattern recognition, so a verbal definition alone will not transfer to a photo on exam day. As each card comes up — honey-colored crusts for impetigo, silvery plaques on elbows for psoriasis, a unilateral dermatomal stripe for shingles — picture the lesion, its distribution and its color before you reveal the back.
Roughly 20 cards a session clears the deck in five days, with the pairs revisited on day six.
