During our antibiotics teaching at medical school we were told that a recent survey of junior doctors had revealed that a significant proportion didn't realise that augmentin, tazocin, and carbopenems were penicillins and as such should not be given to those with known allergies. I devised a "mind-map" summarising the main antibiotics in use using information from the BNF and my own lecture notes. For me, seeing the information laid out in this manner, pinned above my desk as I work, helps me remember the major classes, their relationships with one another, and their major side-effects.
This is a guide to performing a cardiovascular examination in the context of an OSCE exam. It was created by a group of medical students for the free revision website www.geekymedics.com where you can find a written guide to accompany the video.
The way in which this examination is carried out varies greatly between individuals & institutions therefore this should be used as a rough framework which you can personalise to suit your own style.
This animation shows a simplified version of the macrophage's role in the initiation of atherosclerosis. In an atherosclerotic-prone blood vessel, macrophages invade the subendothelial space. Oxidised Low-Density Lipoproteins (oxLDL) present within the vessel wall will bind to scavenger receptors on the macrophage's surface, such as CD36. This will activate the macrophage, and it will phagocytose the oxLDL. As this process continues, the macrophage increases in size and forms a Foam Cell, which is too large to pass between the endothelial cells back into the lumen. Therefore, the foam cells remain in the subendothelial space and are the main cells present within an atherosclerotic plaque.

This poster offers a basic level of understanding of ABGs for medical students. I have also made an ID-card-sized version which can be easily used on the ward. Students can work around the table, looking at pH, then CO2 and then HCO3- and find the answer in the correct box.
The “Arterial Schematic” represents the intricate three-dimensional human arterial system in a highly simplified two-dimensional design reminiscent of the London Underground Map. Each “line” represents an artery within the body; a black circle marks a major vessel, whilst “stubs” stemming from the main lines represent the distal vasculature. The coloured “zones” represent the main divisions of the human body, for example; the yellow zone indicates the neck.
The schematic was inspired by Henry Beck’s work on the first diagrammatic London Underground Map. His aim was to represent complex geographical distribution in a simple and accessible form. He achieved this aim by omitting swathes of information that had plagued previous designers’ versions. Beck’s approach was succinct yet produced a design that was immediately successful in clearly portraying to commuters how to traverse London most efficiently. The “Arterial Schematic” hopes to culminate this idea of communicating complex concepts in a concise manner, mirroring what is expected of medical professionals on a daily basis.
The schematic is a prototype design intended to be part of a series of images that will diagrammatically represent the various systems of the human body. The prototype was inspired by a desire to teach anatomy via a fresh and engaging visual medium. Recent years have seen significant debate over reduced undergraduate anatomy teaching and its later consequences. The hope is that the “Arterial Schematic” and its sister diagrams will inspire students to learn anatomy and encourage them to further their knowledge via other sources.

This is a diagram I created to summarise the immune response, complete with friendly, loveable cartoon immune cells designed in an attempt to make what can be a very complicated and confusing subject seem a little less threatening. The students I taught the subject to loved the "cute" summary format and found immunology to be a much more approachable revision topic as a result!
Since this image has been so popular with all you lovely people, I have also written a comprehensive article on the immune response - complete with lots of illustrations - which is available here on Geeky Medics: http://geekymedics.com/2014/07/02/immune-response/
Enjoy and good luck!
This has been designed to show how the different components of the immune system develop individually and work together. I realised that a flowchart would be an excellent way to demonstrate this and was surprised to find that there wasn’t anything suitable on the internet that linked both the innate and adaptive systems. I know the diagram looks a bit dry but if you spend 5 minutes reading through it, I hope you'll find it useful. I'll hopefully add some images to make it more appealing at a later date.
The flowchart is based on information from lectures and several textbooks and has proven to be an excellent tool for revision and in developing a foundational understanding of the immune system for many students.
