In this Chest X-Ray we can identify a left sided pneumothorax - there is absence of lung markings in the periphery and we can also see a shadow which outlines the edge of the lung. A pneumothorax is caused when air enters the potential space between the viceral and parietal pleura and causes the lung to collapse down under the pressure of it's elsatic recoil. In this case it is likely that the pneumothorax has been caused by trauma as we can see air in the soft tissues on the left side (surgical emphysema - clinically feels like bubble wrap). A pneumothorax can be a life threatening condition. The patient presents in respiratory distress with decreased expansion on the affected side. There will be hyperresonance to percussion on that side but absent breath sounds. The emergency treatment is decompression with a large bore cannula in the 2nd intercostal space mid-clavicular line followed by insertion a chest drain in the 5th intercostal space mid-axilllary line

During my GP placement of this year a different GP to the one who normally taught us called us into his consulting room to see a lady with lung cancer and subsequent clubbing. He then suddenly sprung on us the challenge "Name me 17 causes of clubbing!". My colleugue and I fumbled around with some random suggestions, thrown by the acute onset of the task. We were well and truly embarrassed. As a result, I vowed to devise a way to force the causes of clubbing to stay in my head, and this poem (or rap) is the result. Ideally it would have been in the form of a video with a trendy, young rapper delivering it, but I'm right in the middle of exams and time is precious.

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).
