Callus Debridement Can Be Diagnostic
Calluses form when shear forces and pressure induce the epidermis to reinforce itself. In patients with diminished pain sensation such as in diabetic neuropathy, continued friction from shear forces and pressure evolves the callus into a blister, then a blood blister (figure 1). When I see a bloody foot callus, I know that at some point, there was a break in the dermis. I don’t know if it has healed on its own or if it has expanded into a full blown ulcer because I can’t see past the callus. In fact, some calluses can be so thick I can’t even see the blood underneath! The only way to find out what’s hiding is to debride the callus.

Why did you develop the MELD Score? Was there a particular clinical experience or patient encounter that inspired you to create this tool for clinicians?
Following a trans-jugular intrahepatic portosystemic shunt (TIPS) procedure for complications of portal hypertension, some patients do well and others fare poorly. My colleague in statistics, Mike Malinchoc, and I studied laboratory variables prior to the procedure and identified INR, serum creatinine, serum bilirubin and etiology of cirrhosis being predictive of survival. We developed a score based on these variables and demonstrated it predicted survival in a wide variety of patients with cirrhosis not undergoing TIPS. The score was originally called the Mayo End-Stage Liver Disease (MELD) model and was shown to be superior to the Child-Turcotte-Pugh score.

Dr. John Bedolla is the assistant director of research education and assistant professor of emergency medicine at the Dell Medical School at the University of Texas at Austin. He is also editor-in-chief of ED CLEAR, an evidence-based medical risk reduction program. Dr. Joe Habboushe is MDCalc’s co-founder and CEO. Earlier this year, the two sat down and talked about MDCalc’s content development process and future plans.
Dr. John Bedolla (JB): Hello, I’m Dr. John Bedolla. I am assistant professor of medicine and I’m also the director of risk management for a large EM group. Continue reading “Interview with MDCalc Co-Founder Dr. Joe Habboushe [VIDEO]”
Dr. Kim Medlej
Kamal (Kim) Medlej, MD, is an attending physician at the department of emergency medicine at Massachusetts General Hospital and fellowship-trained in critical care, and a longtime contributor to MDCalc. Here’s Dr. Medlej’s take on applying evidence on managing pain, agitation, and delirium to his patients in the ICU.
Pain, agitation, and delirium (the ICU triad) are common in critically ill patients, and can be challenging for clinicians to manage, both in (1) ruling out and treating potential underlying causes, and (2) choosing appropriate sedatives and analgesics in those patients who need them.
This is a fascinating area of critical care medicine, although it can also be difficult and frustrating. While our insight and screening tools have improved, the management of patients with pain, agitation, and/or delirium remains difficult. This is a large topic with a significant amount of literature and opinions. This brief overview is in no way comprehensive, but more a personal view, approach and practice.

Dr. Jeff Russ
A major task of any pediatric ward provider is to regularly assess a patient’s appearance, vital signs, labs, and risk factors, and integrate these data into a cohesive clinical picture to determine the patient’s acuity and potential need for intervention. This can be especially challenging on busy services or night shifts, where, for example, nurses may divide their time among up to four patients, and a single physician may care for 10–20 patients. Particularly with children, a lot can change between sporadic assessments, making it difficult to triage acuity.

We’ve just hit 300 calculators on our website (and iPhone and Android apps), and we thought it might be a good time for reflection.
By the Numbers:
- The Los Angeles Motor Scale (LAMS) was our 300th calculator!
- We’ve added over 120 calculators in the past year alone.
- MDCalc has been around for 12 years.
- We estimate that we’ve helped with over 15 million patient decisions across the world through our calculators and content in 2016.
- We’re used in 210 countries.
- Despite only having been prospectively validated in 2013, the HEART Score is already our 6th most popular calculator.
- We receive about 5 new calculator requests per week.
- We have 46 featured interviews with calculator creators that give insight into their thinking about their own scores.
- We provide calculators for 50+ specialties.
- We are used by at least 75% of US medical students in their clinical rotations.

Children presenting with head injury are as unremitting in children’s hospitals as the “Frozen” soundtrack, and any physician in a pediatric ED inevitably manages their fair share. The ramifications of missing significant injury to a child’s delicate, developing brain are unnerving. A head CT is central to catching intracranial pathology, but widespread use is not benign, given the risk of malignancy from unnecessary radiation. However, criteria for judiciously navigating this tradeoff remain debated. When is CT appropriate for children with GCS scores of 13-15 and mild symptoms like transient loss of consciousness or vomiting?

When the MDCalc team isn’t scouring PubMed for studies to help our patients (and yours), we also like to read other stuff related to digital health, evidence, and the healthcare industry. It’s always hard to keep up with all the interesting articles on healthcare, and this year medicine has been a popular topic for journalists. So, we thought we’d share some of our favorite articles. Happy reading!

The CHA2DS2-Vasc Score is one of the most widely-used clinical risk scores for stroke. It’s arguably the best validated and is consistently in the top five most popular calcs on MDCalc. Professor Gregory Lip, the newest member of MDCalc’s Scientific Advisory Board, gave us an interview on developing and using the CHA₂DS₂-VASc Score.
Dr. Gregory Lip
Why did you develop the CHA₂DS₂-VASc Score? Was there a clinical experience that inspired you to create this tool for clinicians?
The availability of Non-Vitamin K Antagonist Oral Anticoagulants (NOACs), previously referred to as new or novel oral anticoagulants, has led to a major change in the landscape for stroke prevention in atrial fibrillation (AF). Clinicians are also getting better at understanding how to manage warfarin, recognizing the importance of the average time in therapeutic range (TTR). New data are also re-emerging on the poor evidence for the efficacy and safety of aspirin for stroke prevention in AF.

Ah, sepsis. You can’t solve a problem without defining it, and sepsis has been notoriously difficult to define, let alone treat. The body of data on sepsis is growing, as well as laypeople’s awareness of the disease. Yet it still manages to elude clinicians in many ways. We talked to Dr. Christopher Seymour, Sepsis-3 investigator and creator of the qSOFA Score, about using qSOFA to help in the management of sepsis.
Bonus: We also asked Dr. Seymour about his thoughts on vitamin C in sepsis. Come back to Paging MDCalc next week to see what he (and other critical care docs) had to say! Continue reading “Insights from Dr. Christopher Seymour, Creator of the qSOFA Score”
