Diagnoses at home: Introducing the Remotoscope

The Remotoscope in action

 

Move over iPhone 5 – And make way for the Remotoscope- an iPhone otoscope that will be patient- worthy in the near future.

Georgia Institute of Technology announced in a press release recently, that they are currently developing the ‘Remotoscope’ as an iphone app in combination with a clip-on attachment which instantly transforms a regular iphone into a powerful diagnostic tool, through which physicians can remotely diagnose a large number of ear diseases. Georgia Tech is in the process of improving its software and hardware to make it more user-friendly which will allow parents to just insert the device into their child’s ear canal, make a small video and then directly upload it to the child’s physician who will be able to make the diagnosis.

The technology involved is based on the Cellscope, a mobile microscope developed by the University of California, Berkeley in 2008. Cellscope technology, a small wonder in its own right, has the potential to be used in many different fields like Dermatology, Oncology and now thanks to the Remotoscope, even ENT practice. This microscope technology coupled with the camera and flash of the iphone is what makes the Remotoscope possible.

So how can we put the Remotoscope to work, you may ask? Well, the possibilities are endless really. Parents who live in remote areas all over the world, without ready access to prompt medical care, can use this nifty device to be the eyes of the physician and catch nasty ear infections early before they cause much damage. Physicians can use it to keep an eye on their patients and monitor the efficacy of their treatment. That’s not all. As former medical students we all know how difficult it was to figure out what the doctor had actually wanted us to look at. Well, thanks to the Remotoscope the students can now be shown exactly what the doctor sees and how to diagnose certain diseases based on what they see, in real time. The possibilities are endless.

The remotoscope was no small task to complete. Dr. Wilbur Lam and his colleague Erik Douglas created the start-up Cellscope Inc., starting the project while they were still doctoral students at UC Berkeley. Dr. Lam then brought the project over to Atlanta when he joined the faculty at Georgia Tech and Emory University, and now receives resources from both institutions as well as Children’s Healthcare of Atlanta and the Atlanta Clinical & Translational Science Institute. He hopes to commercialize the device once the FDA trials comparing the Remotoscope’s diagnostic quality to that of the traditional otoscope are complete and it receives FDA approval. The trial is partly being funded by the FDA, through the Atlanta Pediatric Device Consortium.

So the question is when will you see the Remotoscope in stores near you? The trial data will be published at the end of this year and Dr. Lam hopes FDA approval will also follow, allowing the Remotoscope to be a on quite a few Christmas Wishlists soon.

SpiroSmart: the mobile spirometer

 

A spirometer is a device used mainly by respiratory physicians to diagnose and objectively monitor the lung function of patients suffering from common conditions such as chronic obstructive pulmonary disease, asthma and cystic fibrosis.  Traditionally, this device works via  a differential pressure transducer to determine the flow and thus the amount of air that is exhaled as the patient breathes into the machine.  The recent announcement of SpirosmartTM by the University of Washington Department of Medicine and Seattle Children’s Hospital has been a pivotal step towards the management of chronic  lung conditions.

SpirosmartTM is a mobile phone based system that extrapolates lung function using the in-built microphone.  As the user inhales and exhales within a hands-breadth away from the mobile device, the software estimates the lung function measurements via a set of complicated algorithms involving the resonance frequencies of the user’s vocal tract.  Initial pilot studies by the development team involving 52 patients have shown a mean error of 5.1% compared to a clinical spirometer.  The current cost of the software is still under wraps, however due to its portability and ease of use, this device may be a breath of fresh air to home monitoring of chronic lung conditions and detecting exacerbations before they become worse.

Principles of m-Health survey design

Before you start

The first step is to conduct a critical appraisal of existing literature relevant to the research question. Before proceeding further, it is then necessary to consider whether a survey is the most appropriate method to collect the data required to answer the research question.  Appropriate alternatives to surveys include a systematic review or meta-analysis, case-studies, or studies with focus groups. It is beyond the scope of this article to discuss these alternate forms in depth, however, the researcher should be guided by published literature in their topic.  The key steps for survey design will now be discussed. (Refer to figure 1).

Validation of Near Eye Tool for Refractive Assessment (NETRA) – Pilot Study

Background: Uncorrected-refractive-error (URE) is the leading cause of global visionimpairment (VI); 122.5 million people are estimated VI from URE. NETRA is a $30USD clip-on application for smartphones.

Purpose: To validate the NETRA as an alternative to subjective refraction for potential use in resource-poor countries.

Methods: NETRA uses a pinhole mask attached to a smartphone displaying a spatially resolved pattern to the subject. Refractive error is estimated by the patient subjectively aligning patterns by a touchscreen interface on the smartphone. NETRA was compared to subjective refraction in 34 eyes.

Results: The mean Subjective Spherical Equivalent (SSE) was -0.65D (std 2.79, 95%CI ±0.97) Two-sided T-test showed that mean SSE is not statistically significantly different (two sided t-test; t=1.6742 p=0.1036, 95% CI±0.29) from the mean NETRA Spherical Equivalent (NSE) .  Mean difference of Spherical Equivalents (NSE – SSE) was 0.24D (Std 0.84, 95%CI ±0.29). And NETRA produced a mean VA improvement of 0.44LogMAR (Std 0.52, 95%CI±0.18), or four Snellen lines.

Conclusion:In settings where access to a trained refractionist is not possible, NETRA has the potential to estimate refractive error closely enough to render an individual no longer VI from URE. NETRA is potentially a cost-effective tool in meeting the VISION2020 goals to eradicate avoidable blindness and warrants further testing in resource-poor settings.
