Weber's and Rinne's test

This one is pretty well known but thought I'd add it anyway.

Weber's test -
tuning fork on forehead.
Loud on one side:
= conductive loss on same side
or
= sensorineural loss on opposite side

Rinne's test -
tuning fork next to ear and on mastoid process.
Normal = Air louder than bone (+ve rinne's)
Conduction loss = Bone louder than air (-ve rinne's)
Sensorineural = Both the same

Next time you see someone actually doing this test, please take a photo and sent it to me!

Anterior Pituatary Hormones

These are the anterior pituatary hormones.

Think of an ant (Anterior) swimming around in a bowl of milk (Prolactin) with some alphabet cereal (All the hormones which are abbreviated).

Posterior pituatary does everything else (Oxytocin + Vasopressin).

Grouch-er's

Gaucher's Disease

This is a lysosomal storage disease caused by hereditory deficiency of glucocerebrosidase. Characterised by hepatomegally and splenomegally due to lipid not being broken down by glucocerebrosidase.

So...here is oscar the grouch (Gaucher's) in his dustbin (distended abdomen from splenomegally & hepatomegally) drinking Cerebro-cider (gluco-cerebro-sidase) which causes neurological complications.

Antibiotic Classification

Please use the buttons above to vote for whether this one works. Have been working on this for a while and it may only work in my head!

Each picture above is just a way of linking a random antibiotic name with an actual class. Such as Quinolones -> "Quick Sip" -> Ciprofloxacin.

For adverse reactions add:

• The pepsi van is driven by a red man (vancomycin causes "red man" syndrome)
• The gentleman has to shout "ALLO GUVNOR" since he is deaf (ototoxicity in gentamycin)

Also, on the penicillin side of things here's how I remember the Beta-Lactams:

ECG interpretation with one glance

Often I find someone hands you an ecg print out, points to one lead and says "...obviously the defect is antero-lateral to the septal portion of the apex" (or something similar). So here's a neat picture based way to remember which lead covers which area.

All ECG's are presented in this format:

and I like to superimpose the following picutres:

So Lead I, aVL, V5 and V6 are lateral (picture of Caffe Latte), Lead II, III and aVF are inferior (Info sign), chest leads V1 and V2 are septal (7 in french, sept), chest lead V3 + V4 are anterior (Ant). Don't worry about aVR - I don't think anyone ever does. So just like in the kids game, all you have to do is remember where each of the pictures are.

What is an EEG?

Ok, so people often get confused over what exactly an EEG is. Time to look at some EEG fish....

In our fish tank we have loads of fish swimming around randomly. There are also 3 cameras looking at different parts. The first sees only one fish (how sad), the next sees 3 fish swimming to the left and the next sees loads of fish swimming to the right. If we add in a bonus camera then we could probably figure out which way the fish were swimming at a certain depth.

Replace cameras with electrodes and fish with action potentials and you've got an EEG. Remember the crazy squigly line trace you get from an electrode is the result of groups of neurons (fish) firing (swimming).

Signs of Infective Endocarditis

A series of hand gestures to remember the signs of infective endocarditis.

• Live long and prosper (Captain Janeway) - janeway lesions found in the palm and soles of foot.
• Spider upside down in OS-tralia - oslers nodes found in finger pads and toes.
• Nails - splinter haemorrhages
  

Genu Varum / Valgum

Bulbar Nerve Lesions

A lesion in the vagus nerve (CNX) causes the uvulA to deviate Away from the side of the lesion (uvula to the right, lesion on left side of brain).

A lesion in the hypoglossal (CNXII) causes the Tonge to deviate Towards the lesion (deviation to the left = lesion on the left).

SSRI's

Senor P.F.C is so sad. The only thing that makes him happy is pushing around his pram.

Sertraline
Paroxetine
Fluoxetine
Citalapram

*Sertraline is also called so as it inhibits the SERotonin Transporter protein.

Zones of Adrenal Cortex

Or... "the deeper the sweeter".

*thanks again to Nick

Raynauds Phenomenon

Russian Flag = Raynauds Phenomenon

White: pale, cold and numb
Blue: cyanotic
Red: return of blood flow (rubor)

*thanks to Nicolas for this one

CXR Heart Failure

*apologies, this wasn't posted quite in time for today!
....also this is nicked from oxford handbook.

Congenital Rubella Syndrome

Congenital Rubella syndrome is characterised by:

• Microcephally
• Cataracts
• PDA

Most risk to foetus if rubella infection is in 1st trimester

Calcium Channels

Love: L-type = generally cardiac (verapamil)

Thought: T-type = generally neuronal (ethusuxamide)

Moclobemide

Beers and ales also have a lot of tyramine and so will cause the "cheese" effect*. MOclobemide is a reversible monoamine oxidase inhibitor and so has less effect -> you can go to Moe's and have a beer.

*cheese effect a result of IRReversible MAOI.

Acute Asthma Management

How to manage acute asthma attacks! As you panic you will scream ..... O SHIT.

Oxygen - high flow 100%
Salbutamol -Nebulised

Hydrocortisone - given IV
Ipratropium Bromide -(Anticholinergic given IV)
Theophylline - (Phosphodiesterase inhibitor given IV)

You can also add O SHIT MAN:
Magnesium Sulphate
ANaesthetist!

Thanks to Yassir for this one.
