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

Mnemonics on poisoning

Indications for Hyperbaric O2 therapy in CO poisoning - NEPAL 40

Neurological toxicity (the most indicative being cerebellar symptoms)
ECG changes (the need for DCCV or Defib is a relative C/I to hyperbaric O2)
PregnAncy
Loss of consciousness
>40% CO-Hb


Symptoms of Lead Toxicity - LEAD (kudos to Esben Vogelius)

Lines across gums (Burton's Lines - poor dentition is usually a prerequisite for this sign, so rarer in children)
Erythrocyte stippling (also Sideroblastic anemia)
Abdominal pain
Drop, foot or wrist (Lead neuropathy is largely motor)
also, don't forget to look for neurodevelopmental symptoms

Graft versus Host Disease - Symptomology

acute GvHD occurs within 100 days of transplanting (immuno-competent) donor cells into an immuno-deficient host.

the classic triad of symptoms correspond to the abbreviation for this syndrome (ie. GvHD)

Gastroenteritis - diarrhoea
Hepatitis - biochemically evident, with or without jaundice
Dermatitis - ranges from mac-pap rash (that can be painful/pruritic) to exfoliative erythroderma

Bony Metastasis

Common Tumours Metastasising to bone - L.P. Thomas Kisses Best (or Breast)

Lung
Prostate
Thyroid
Kidney
Breast


Common sites of skeletal metastases - CASPERSKY (in order of frequency)

CA - reminder that bony malignancies are usually secondary
Spine
PElvis
Ribs
SKull
Y - looks a lil' like your femur 'eh? (ie Proximal Long Bones... ...rubbish I know =P)


HUS/TTP - CRAFTY syndromes

Symptoms of HUS/TTP - CRAFTY (thank you ValueMD)

CNS symptoms -> visual symptoms, paresis, fits, changing conscious levels
Renal failure
Anemia -> Microangiopathic Haemolytic Anaemia (MAHA)
Fever
Thrombocytopenia
Y does it occur?
In HUS/TTP there are autoantibodies against the ADAM-TS13 metalloproteinase. ADAM-TS13 prevents the polymerisation of vWF -> hence when it is inhibited, vWF polymerises into larger, more active molecules - causing more platelets to clump to it and resulting in a fall in circulating platelet counts and intravascular microthrombi.

Causes include: E coli 0157, Shigella, Adenovirus, Pneumococcus, OCP, Pregnancy, SLE, HIV [haven't got a mnemonic for this list yet =( ]

Deadly Headaches - THIS GEM

Deadly headaches that should be excluded - THIS GEM

Temporal arteritis
Hypertensive headaches
ICP increased
Sub-arachnoid haemorrhage

Glaucoma
Encephalitis

Attempts (prev suicide attempts + exploring the lethality if any)
Nothing to live for (e.g. no family support, career, sense of hopelessness)

Trigger (any precipitants for the suicide attempt?)
Help - did patient seek help after the attempt
I=IDEAS and INTENTION (ie. explore suicide plans & confidence level to see it thru)
Substance abuse

Ilness (Medical or Psychiatric)
Suicide in the family
N’T = suicide NOTE (also telling others prior to attempt)

Final arrangements (eg. final goodbyes, leaving a will)
Access to suicide means (e.g., firearms)
Isolation (ie. made efforts to be undiscovered?)
Regret surviving the suicide attempt??
