Tired Of Needles? Measure Your Glucose Levels With An iPhone

skin_tattoo[1]Researchers at Northeastern University are using nanosensors implanted into the skin — similar to a tattoo — and a modified iPhone to measure sodium and glucose levels in patients. The implications for this could be tremendous, but first, here’s how it works:

“The team begins by injecting a solution containing carefully chosen nanoparticles into the skin. This leaves no visible mark, but the nanoparticles will fluoresce when exposed to a target molecule, such as sodium or glucose. A modified iPhone then tracks changes in the level of fluorescence, which indicates the amount of sodium or glucose present.”

Camera Phone Clip-On Device Can Diagnose Cataracts

Researchers at MIT have developed a cheap and easy to use system, called Catra, that uses a cameraphone clip-on device to map out cataracts.

The technology functions by sweeping the eye with a beam of light and using the phone’s camera to detect fuzzy spots. It can provide both a map of the cataracts and maybe help make an overall assessment of whether surgery might be necessary.

From MIT News:

While the standard test for cataracts in an ophthalmologist’s office assigns a score on a scale of 1 to 4 — from no cataracts to completely blocked vision — the new, inexpensive test actually provides much more information. Media Lab graduate student Vitor Pamplona, a member of the team developing Catra, explains that it “scans the lens of the eye and creates a map showing position, size, shape and density of cataracts.” Read more »

New Blood Pressure Monitor For iPhone Costs 4 Times More Than Off-The-Shelf Version

One of the most interesting things I saw at this year’s Doctors 2.0 and You event was Withins’ Blood pressure monitor.

This iPhone-connected blood pressure monitor made its first appearance at CES, but you’ll finally be able to order one of your own today. Compatible with iPhone, iPad, and iPod touch, the $129 accessory costs three to four times as much as off-the-shelf blood pressure monitors, but integrates well if you’re looking to pair it with your Withings scale for a complete vitals management solution.

There’s An App For That: Helping Medical Students Master The Abdominal Exam

1 A strong abdominal exam is a must-have clinical skill for an aspiring healthcare professional.  Diagnoses spanning cirrhosis, appendicitis, hernias, peritonitis, aortic aneurysms, and cholecystitis, for example, can be suspected and even made via abdominal exam.

Unfortunately, secondary to factors which include an increasing dependence on imaging and other diagnostics, time constraints in the practice of medicine, and fewer chances for bedside instruction in medical education with work-hour regulations, physicians rely increasingly less on their physical exam skills today than has been the case in the past.

In that manner, here we review the Answers in Abdominal Examination App, released in May 2011 by Answers in Medicine.  Answers in Medicine, which specializes in presenting medical content via short modules in audio or video format for healthcare professionals, has developed a number of medical apps, including Answers in Alcoholic Liver Disease, Answers in Ulcerative Colitis, Answers in Crohn’s Disease, Answers in Irritable Bowel Syndrome, and Answers in Dyspepsia, to name several.

Pediatric Emergency Drug Calculator: Great Idea, Not Ready For Prime Time

Photo Jun 12, 10 15 47 PM Pediatric Emergency Drugs is designed to be a quick med list calculator for pediatric emergencies. For folks who deal with pediatric emergencies have the challenge of not only determining the proper drugs to use, but also to get the dosage right by age.

At the first page you are met with a screen to enter the age of the child and either allow the program to pick the estimated weight or put your own weight in. This is a nice feature as often in pediatric emergencies patients arrive through the door needing immediate care and a weight is unavailable. The estimated weight it appears to pick is the 50% for a boy of the selected age. Allowing you to pick the gender of the child would be helpful in narrowing down the weight a little further since girls of a given age would weigh a little less.  Another option would be to allow the use of Broselow colors. These days the standard for most ERs is the Broselow tape which is a plastic foldable tape that doses based on length.

Once you select your patient you have a section of drugs broken down into: cardiac arrest meds, infusions, and bolus drugs. The cardiac arrest meds are short a few drugs. There are no drugs for treating ventricular fibrillation (amiodarone)  and they do not make mention of the dose of electricity for synchronized cardioversion (only for defibrillation). The infusion list assumes you are mixing all drugs in 50mL bags which is not usually the case. (we usually use 100 or 250mL bags for drips). Also, in America thanks to JCAHO regs medicated infusions need to be have standardized concentrations and not use the “rule of 6” employed by this program. The list of bolus drugs is missing a few key drugs as well such as midazolam and hydrocortisone for sepsis. Read more »

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
