This 3D medical animation shows a blood clot forming in a lower leg vein, creating a deep vein thrombosis, or DVT. When the thrombus breaks free of the valve, it is called an embolus, and travels toward the heart and lungs. The animation ends by showing the embolus lodging in the lung tissue forming a life-threatening pulmonary embolism (PE).
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 the first of two part tutorial on pulmonary oedema. Here, the underlying physiology is covered.
This podcast can be watched in isolation or in conjunction with the second part which covers the clinical aspects.
This is a project I did for a PBL session. I wanted to explain the ways in which the tuberculosis bacterium infects the body and causes symptoms in an interesting and fun way. I have dyslexia and a visual learner and I find that I take in information more effectively when diagrams or pictures are used. I’m also a huge fan of comic book which is why I chose to use this as a medium to present this information. This comic illustrates M.Tuberculosis’s journey through the body and his battle with the host immune system.
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!
ARDS – acute respiratory distress syndrome and ALI – acute lung injury, are essentially the same disease; ARDS is the more serious end of the spectrum, and for the purpose of this article, we will also refer to the disease as ARDS
All blood cells develop from haemocytoblasts The process is called haematopoiesis (sometimes just haemopoiesis) Haemocytoblasts are also known as pluripotential stem cells. These cells can replicate themselves as well as differentiate into other cells, thus providing the constant supply of blood cells. The turnover of cells is very quick:
