WELCOME !!

Just a few words to start off, I wouldnt' dare claim credit for ALL the mnemonics on this blog. In fact, a number of the cleverer mnemonics you see either are the good work of other doctors/students or have been shamelessly lifted out of medical books.

If you've got a medical mnemonic gem to contribute, feel free to submit it to dingydingding(at)googlemail(dot)com

Last but not least, please feel free to point out any errors or improvements that can be made in any of the mnemonics!! Otherwise, you can always click on the ad-links too if you wanna do your part =P

How severe is your Ulcerative Colitis?


The Truelove Criteria (awesome name BTW...) grades the severity of Ulcerative Colitis based on 5 parameters:

UC Severity - She Hasn't Even Finished Pooping!

Stool frequency per day (has to be bloody stool)
Haemoglobin
ESR
Fever
Pulse rate


MILD
MODERATE
SEVERE
Stool frequency /day (bloody stools)

<4



Moderate severity are values that are in between MILD & SEVERE
>6
Haemoglobin

>11.0
<10.5
ESR

<30
>30
Fever

Afebrile
>37.8
Pulse rate

<70
>90

Myasthenia Gravis associations

Diseases associated with Myasthenia Gravis - STRAPD (read: 'strapped')

S - SLE or Sarcoid
T - Thymoma or Thyroid disease (hypo/hyper)
RA - Rheumatoid Arthritis
P - Pernicious Anaemia
D - the 2 DMs : diabetes mellitus & dermatomyositis

PGA - more Addison's than Tiger Woods....

Some quick notes about the group of diseases known as Polyglandular Autoimmune Syndrome (PGA).

  • 2 types exist - PGA I and PGA II (PGA II is the MORE COMMON of the two)
  • Each is a constellation of THREE diseases - but the diagnosis can be clinched by just having only 2 out of 3.
  • The common link between the two is autoimmune Addison's disease

PGA I:
Parathyroid - autoimmune HYPOparathyroidism
Gandida (boo hoo....this represents a new low in mnemonic making) - chronic mucocutaneous candidiasis
Addison's disease

Chronologically, chronic mucocutaneous candidiasis appears first, followed by hypoparathyroidism, and lastly Addison's.

PGA II - also with Addison's and 1 of the 2:
1) Type 1 DM (contrast this with candidiasis, which is common in Diabetics)
2) autoimmune THYROID disease - more commonly Hashimoto's than Graves' (contrast this with Parathyroid involvement of PGA I)

Parathyroidectomy - to chop or not to chop?

The following are definite indications for SURGICAL management of HYPERPARATHYROIDISM  (based on American National Institutes of Health consensus)

Indications for Parathyroidectomy - Calcium BuRNS !!!

Calcium - either SERUM > 3.0 or URINARY Ca2+ markedly elevated
BMD decreased
u (null)
Renal impairment
Nephrocalcinosis &/or Nephrolithiasis
Symptomatic hypercalcemia that is severe

Conservatively managed HyperPTH patients require YEARLY:
1) serum calcium 
2) U+Es
3) Renal USS
4) BP
5) & a BMD every 2-3 years.

I've got some NERVE plagiarising these mnemonics

Ha Ha. Corny.

Here are two commonly seen/available mnemonics regarding neuritides:

Causes of Carpal Tunnel Syndrome - MEDIAN TRAP
Myxoedema (ie. Hypothyroidism)
EtOH
Diabetes Mellitus
Idiopathic
Amyloidosis
Neoplasia

Trauma
Rheumatoid Arthritis
Acromegaly
Pregnancy 



Causes of Mononeuritis Multiplex - WARDS PLC (Courtesy of the good ol' Cheese & Onion)
Wegener's Granulomatosis
Amyloidosis
Rheumatoid Arthritis
Diabetes Mellitus
Sarcoidosis/SLE

Polyarteritis Nodosa
Leprosy
Carcinomatosis

**rule of thumb: think infiltrative diseases (ie. Sarcoid/Amyloid) and Vasculitis/CTDs (SLE, RA, WG, PAN)

Nephrotic VS Nephritic - where one letter makes a world of a difference

Back when I was a medical student, I thought my nephrology lecturer was a fickle dyslexic - which explained why he kept flitting between nephritic and nephrotic in his lecture notes.  And I wonder why I never really grasped either syndrome until now... ...

Features of nephrotic syndrome - "NAPHROTIC"
Na+  - you may rarely get hyponatremia in nephrotic syndrome; this is also a reminder that there is an intense pathophysiologic retention of sodium due to reduced oncotic pressure
Albumin - serum levels are decreased
Proteinuria >3g/day
Hyperlipidemia
Renal vein thrombosis
Oedema
Thrombosis
Infections - more prone to them due to loss of Ig in the urine
Coaguability

Features of nephritic syndrome - "HO HO"
Hematuria - not forgetting the all-important RED CELL CASTS
Oedema
Hypertension
Oliguria (secondary to developing azotemia) 

Admittedly, the 2nd mnemonic is pretty weak =P
I guess the take home point is to be aware of the complications that can arise in patients with nephrotic-range proteinuria.  On the other hand, one needs to be very wary of deteriorating renal function in patients who develop red-cell casts.

Erythema Nodosum VS Pyoderma Gangrenosum

Causes of Erythema Nodosum - DISSTend

Drugs (OCP, Penicillin, Sulfonamides)
IBD
Streptococcal infections
Sarcoid
TB
end - just a reminder that this the mnemonic for erythema nodosum


Causes of Pyoderma Gangrenosum - I Hate RPGs (I really do BTW...)
IBD
Hepatitis / Hematologic malignancies
RA
PG - reminder that it's Pyoderma Gangrenosum we're talking about here...
