How I Do It: Callus Debridement and the Diabetic Foot

Dr. Haywan Chiu

Haywan Chiu, DPM, is a practicing podiatrist in Albuquerque, New Mexico. He has a special interest in the diabetic foot. Haywan runs Diabetic Foot Guardian, an easily digestible resource for patients regarding feet and diabetes.

 

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.

Centor’s Corner: The Story of FENa

Centaur Centor3 (1)

Centor’s Corner

September, 1976: I was a 2nd year internal medicine resident at the Medical College of Virginia.

My attending physician, Dr. Carlos Espinel, had just published a now-classic article: The FENa test.

So that month, I had the wonderful opportunity to understand the rationale behind a test that I now have used for over 40 years.

Interview with MELD Score Creator Dr. Patrick Kamath

Dr. Patrick S. Kamath

Patrick S. Kamath, MD, is a professor of gastroenterology and hepatology at the Mayo Clinic in Rochester, Minnesota. His research interests include acute-on-chronic liver failure, nonalcoholic fatty liver disease, polycystic liver disease, Budd-Chiari syndrome and hereditary hemorrhagic telangiectasia. Dr. Kamath is internationally renowned as a leading researcher in hepatology and has also won numerous awards as an educator.

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.

From Evidence to Practice: Managing Pain, Agitation and Delirium in the ICU

Dr. Kim Medlej

Kamal (Kim) Medlej, MD, is an attending physician in 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.

Centor’s Corner: FeverPAIN versus Centor Score

Centaur Centor3 (1)

Centor’s Corner

Editor’s note: Centor’s Corner is a new Paging MDCalc column featuring our favorite pharyngitis guru, blogger extraordinaire, and Scientific Advisory Board member Dr. Robert Centor, with regular insights from Dr. Centor on the applications of evidence to practice and musings from an experienced clinician. To comment on Centor’s Corner articles, please e-mail the editor at rachel@mdcalc.com or tweet directly to Dr. Centor @medrants.

On Twitter recently, several British tweeters discussed whether they should use the FeverPAIN Score or the Centor Score.  Obviously I have a bias here, but I will try to discuss this issue dispassionately.

Interview with Dr. Ilene Claudius, Part 2 of 2: Pediatric Mass Casualty and Systemic Failures in Child Abuse

dr-ilene-claudius

Dr. Ilene Claudius

Can you tell us about your research in pediatric mass casualty incidents (MCI)? How did you develop an interest in pediatric mass casualty? Was there a particular patient experience that you had?

I haven’t had a personal experience with it, necessarily—we’ve certainly had some overwhelming car accidents, but nothing to the level that I would call a true pediatric mass casualty incident. These are always tragic events, and especially after Sandy Hook, it became clear that kids could make up a sizable portion if not the entirety of the victim population of an MCI.

We’ve done a lot of work in the PEM [pediatric emergency medicine] community on general community hospitals being ready to see a lot of kids in general. I work with an organization called COPEM [Committee on Pediatric Emergency Medicine] that looks at our pediatric receiving hospitals and makes sure they’re up to standard in terms of delivering pediatric care and having the appropriate supplies. And that’s just for a single routine pediatric patient. So the thought of how a group of very traumatized pediatric patients simultaneously is going to be handled is something we discuss a lot.

The PEWS Score: Can an Algorithm Predict Worsening Illness in a Hospitalized Child?

By Jeff Russ, MD, PhD – Pediatric/Child Neurology Resident, UCSF

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.
