The top medical cases of May 2018
A migrating bullet, the results of the ice cube challenge, and “the magic of the Lewis lead” were among the most engaging cases shared in Figure 1’s medical community in May.
Every day, healthcare professionals in 190 countries use our free app to sharpen their clinical skills. Every month, we compile the cases they found most engaging. We calculate this based on:
Community Metrics: The number of times these cases were viewed, discussed, and shared by the more than 2M healthcare professionals on the platform.
Clinical Value: The quality, complexity, and educational merit of our top cases, as assessed by our medical and community teams.
May’s most engaging cases featured both unusual presentations and valuable discussions. Each offers a unique window on healthcare as it happens.
An 11-year-old female with no previous medical history presents to her family doctor with two lesions on her arm. Her doctor shares the case on Figure 1, saying, “This lesion has been there for 3 days, new one popped up today. Blister formed spontaneously; negative Nikolsky’s sign. Both are mildly indurated and mildly tender. Any takers?”
A dermatologist offered up this suggestion:
Newest video trend… placing salt then ice cube on the arm. Result can be as significant as third degree burns! Looks like they tried it once, then on the second attempt left it on long enough to cause dermal burn.
The family doctor returned to say this was in fact correct, responding that:
Upon further interview, the patient admitted to the ice cube challenge. They are both on the non-dominant side, a solid piece of history for self-inflicted wounds. No reasonable suspicion of abuse or depression.
Changing the configuration of ECG leads on a patient can enhance the detection of atrial activity in arrhythmias. One such configuration is referred to as the Lewis lead, and in this pair of cases, a paramedic demonstrates how the different placement of electrodes offers more clinical insight.
The paramedic who shared this ECG explained it as follows:
The only thing you are getting out of a Lewis lead is either a hidden atrial activity that you never saw or a suspected atrial activity that is now more clear. Atrial rate in atrial flutter is usually 300 bpm but it’s possible for the rate to be 250 bpm to 350 bpm.
And a registered nurse added:
So Lewis leads are most beneficial for atrial flutters without clear F-waves. Essentially, it is a clearer view of the atria. In 2:1 conduction it is common to have only a QRS and a T-wave, with limited evidence of atrial activity. In these cases, Lewis leads are beneficial, but can be used to help to evaluate atrial activity whenever it is in question.
“Last night my patient was shot in the leg and exploratory surgery was done to find the bullet,” a registered nurse reported in this text case.
“The trauma surgeon couldn’t find the bullet, so the patient was taken for a full body CT scan. The bullet was found up close to the right atrium. The bullet hitched a ride from the iliac vein up to the heart. Cardiothoracic surgery got involved and retrieved the bullet. Patient is still intubated but following simple commands and moving all extremities. Has anyone ever heard of this occurring? Has this ever happened in your hospital?”
Several healthcare professionals shared their experiences:
“I have - with buckshot, but not a single bullet,” said one dermatologist.“Yes it was a Kirschner wire [used to repair a] clavicular fracture 20 years before. Patient has MI [myocardial infarction] symptoms and during coronary angiography the wire’s found in the right ventricle,” said a vascular surgeon, who shared this journal article on the phenomenon.“The most famous case in the US was former VP Dick Cheney’s friend, who he accidentally shot while they were hunting,” a registered nurse said. “Shotgun pellet traveled to one of his coronaries, causing a ‘mechanical’ MI! I’ve had two patients with serious bullet migrations.”
