Figure-1-homeSocial media has revolutionaized the mode of interaction with family and friends setting expectation to have update on your Facebook page every minute.  Yet another leap in the technology is growth of social media on mobile platforms, which is the future of social media as evident from $19 billion acquision of Whatsapp by Facebook.  

Healthcare community has seen activity in socail media area geared towards health and health issues.  Figure 1 is one such company started in Canada referred as instagram of doctors. Figure 1 raised $2 million of seed funding in December 2013 by a crowd-sourced community of physicians readily sharing medical images. Poor selectivity of medical imaging in Google images and expensive private medical image libraries motivated Dr. Joshua Landy, an Toronto-based Pulmonary/Critical Care specialist, to give birth to Figure 1.

What are main features of Figure 1, medical instagram?
Figure 1 is a free platform that offers physician verification (via personal registration or Doximity integration). Figure 1 allows:

  • Sharing of patient images by individual physicians
  • Patients can sign consent form that is individualized by clinic or a genernal form from Figure 1
  • Ability to  de-identify photos by allowing the uploading user to block out faces, tattoos, and distinguishing features of patients.figure1
  • Also developing browseable image categories  (by specialty or anatomy).
    • This provide easy access to the massive database topically
    • Users can suggest alternative categorizations (each image can be in multiple categories) to assist in future discovery of these images.
  • Retains a clean, simplified, but highly functional user interface.

What platforms are supported by Figure 1?
You can access Figure 1 through iPhone, Andriod app and through internet/ web. Andriod app and web browsing capability has been added within last week.  Image categorization has not been yet incorporated in Android platform, but the Figure 1 team expects the Android and iOS team to have feature parity over the next few months.

What is the current traffic on Figure 1?
Figure 1 is seeing steady users with over one million views per week and each image viewed thousands of times.  The uploads receive multiple comments, with many comment sections exceeding 5 posts.

What countries have access to Figure 1?
Figure 1′s is available internationally in Ireland, the UK, Australia, New Zealand, the USA, and Canada.

Furthermore, the Figure 1 team highlights a particularly interesting finding or case each week in their Image of the Week mailing list. Figure 1’s user experience is limited to search and viewing of images and is looking to expand this capability to provide users much more rich experience in near future.  KAH is excited by the platform created by Figure 1 and look forward for Figure 1 to be a part of Facebook family!

Oral-B-SmartSeries-Bluetooth-Electric-ToothbrushToothbrush has been a simple day to day gadget that is useful in keeping your teeth clean. Development of battery operated and further more recharageble toothbrush provided better users experience and more control on dental hygiene. Now we are entring a era of merger of information technology with medical devices, which is touted to give growth to the medical device sector. Beam technologies came out with first connected manual toothbrush in 2013, cleared by FDA in 2012 for $24.99.

Oral-B, one of the market leader in dental products made announcement of Bluetooth-connected electric toothbrush line, named SmartSeries to be available in iOS and Andriod this year.  The SmartSeries tooth Brush will be available to users in Germay and USA in June 2014.

How many modes does Oral-B SmartSeries toothbrush has?
The SmartSeries has six different brushing modes:

  • Daily cleaning
  • Deep clean
  • Whitening
  • Gum Care
  • Sensitive
  • Touge cleaning

Theese modes can be personalized by the user with help of their dentist.

How does Oral-B SmartSeries toothbrush help user?
SmartSeries app will start timing when you will start brushing with the selected brushing routine.  Also you will

  •  get alert message if too much pressure is applied
  • see graphical view of brushing performance over time

The app also suggests nearby dentists, and logs your appointments. It reminds you to replace your brush head every 90 days, with a link to buy more, and pictures to make sure you pick the right one.

“[Our Bluetooth connected toothbrush] provides the highest degree of user interaction to track your oral care habits to help improve your oral health, and we believe it will have significant impact on the future of personal oral care, providing data-based solutions for oral health, and making the relationship between dental professionals and patients a more collaborative one,” Wayne Randall, vice president of Global Oral Care at Procter and Gamble.

What is price tag on Oral-B SmartSeries toothbrush?
The toothbrush is set to launch with price tag of £199 in the UK, or 219 euros in the rest of Europe, and £219 in the US.

Is Oral-B first company to launch connected toothbrush?
Oral-B is the first big company to launch connected toothbrush, but not the first in this space.  Two other companies have connected toothbrush in market

  • Beam Brush – manual toothbrush launch in 2013, FDA approved in 2012
  • Kolibree – Launched electric brush in 2014.  The detects whether you hit all hard to reach places between gums and teeth along with brushing time

 The connected toothbrush does look like a promishing technology, but how much will you pay for such a toothbrush?  Also, with everything connected to internet, it will be interesting to see, how much of the data is analyzed by the user or clinic and put to use to further refine medecial care such as dental hygiene.  Dental hygiene is definetly important, but is connected bluetooth brush from companies like Oral-B an overkill?

Erectile dysfunction is a sexual dysfunction characterized by the inability to develop or maintain an erection of the penis during sexual performance. Medtronic, one of the medical device giants, tested use of stents in opening up arteries in penis to help erectile dysfunction.

Penile erection is the hydraulic effect of blood entering and being retained in sponge-like bodies within the penis. The process is initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the penis.

Erectile dysfunction is a sexual dysfunction characterized by the inability to develop or maintain an erection of the penis during sexual performance. Besides treating the underlying causes such as potassium deficiency or arsenic contamination of drinking water, the first line treatment of erectile dysfunction consists of a trial of PDE5 inhibitor drugs.

Drug-eluting stent (DES) for the treatment of erectile dysfunction
Dr. Jason Rogers of UC Davis Medical Center Sacramento, CA reported at the VIVA 11 conference in Las Vegas this week about the study on Medtronic’s drug-eluting stents that help men with erectile dysfunction not responding to treatment with drugs. The trial also encountered logistical problems related to the uncharted complex terrain of the pelvic vasculature.

The medical device company conducted a study on 30 men, by placing the zotarolimus coated stents into the internal pudendal artery, which accounts for the blood supply to the penis. This intervention opened the blood vessel and improved blood flow towards the penis. The treated men showed improvements on the Index of Erectile Dysfunction scale and there were no adverse effects noticed. Importantly, the treated men were excited and happy with the treatment and its effects. Ultrasound tests also confirmed that the blood flow improved significantly after the placement of the stent at the beginning of the study.

Participant surveys showed that three months intercourse success improved by 38%.  Intention-to-treat analysis showed that 59% percent of patients experienced an improvement in erectile function, as measured by an International Index of Erectile Function (IIEF-6) domain score of 4 points or greater.

The trial involved a rare collaboration of vascular interventionalists and urologists/ sexual-medicine specialists. Rogers’s co-investigators were Dr Krishna Rocha-Singh (Prairie Vascular Institute) and Dr Irwin Goldstein (San Diego Sexual Medicine, CA).

Stent are metal wire mesh structured implant that are are most commonly used to open clogged arteries of heart.  Application of stents for erectile dysfunction can open new avenues for stents, which have seen a stagnant growth in the cardiovascular regime.

Cardiac resynchronization therapy (CRT)  also called a bi-ventricular pacemaker an important device for treatment for symptoms associated with congestive heart failure (CHF) caused by weakening of the heart muscle (cardiomyopathy). This device is implanted in the body of the patient.

A CRT system consists of the pulse generator and three thin, insulated wires called leads.

The pulse generator is a small computer like device. It uses lead wires to deliver tiny amounts of electrical energy to the ventricles.

The energy impulses help the ventricles contract at the same time, or “resynchronize.”

When the ventricles pump together, the heart can work more efficiently. This helps the body get the blood it needs to live and work.

 How does the heart’s electrical system work?
The heart is a muscular pump composed of 4 chambers. The 2 upper chambers are referred to as the atria, and 2 lower, or main pumping chambers, are known as the ventricles. The coordinated pumping action of these 4 chambers is controlled by an electrical system that is contained in the heart muscle. The normal heartbeat is stimulated by a tiny electrical signal that originates in a region of the right atrium known as the sinoatrial or SA node. The electrical signal then spreads through both atria, causing them to contract and squeeze blood into the ventricles.

The pacemaker continuously monitors the patient’s heartbeat and delivers a tiny, imperceptible electrical charge to stimulate the heartbeat when necessary. Most pacemakers typically have 2 electrodes (or leads), one in the right atrium and one in the right ventricle, which permit the pacemaker to maintain the normal coordinated pumping relationship between top and bottom of the heart. These leads are connected to a battery pack (pulse generator) placed under the skin in the upper chest. In addition to the 2 leads (right atrium and right ventricle) used by a common pacemaker, CRT pacemakers have a third lead that is positioned in a vein on the outer surface of the left ventricle. This allows the CRT pacemaker to simultaneously stimulate the left and right ventricles and restore a coordinated, or synchronous, pumping action.

New adaptive cardiac resynchronization therapy (CRT) system by Sorin Group
Sorin Group
, a manufacturer of devices for the treatment of cardiovascular disease launched their new cardiac resynchronization therapy (CRT) system with CE approval. The SonR system comprises of the Paradym RF SonR CRT-D device, which generates and controls the resynchronization stimulus and the SonR tip atrial pacing lead which incorporates a hemodynamic sensor capable of estimating LV dP/dtmax, an index of cardiac contractility.

The system is able to optimize the delivery CRT by regularly estimating the contractility of the heart via the hemodynamic sensor and adjusting the delivery of stimulus accordingly. This system offer each patient a tailor-made programming of the timing between electrical impulses sent to different parts of the heart (CRT settings) on a regular basis. Current optimization methods include echocardiography and other device based timing features.

SonR sensor uniquely measures patient’s cardiac muscle vibrations. These real-time measurements are transmitted to the CRT-D device which uses them to determine the best settings for the patient. Every week, the system automatically optimizes to adapt to the patient’s changing condition.

Lipids are integral part of the body and are essential for functioning of the body at molecular level. Researchers have been utilizing fluorescent proteins to visualize lipid molecules.  A professor at University of Illinois, Chicago demonstrated the first successful quantification of membrane lipids in a living cell in real time.

Lipids constitute a broad group of naturally occurring molecules which include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others. The main biological functions of lipids include energy storage, as structural components of cell membranes, and as important signaling molecules.Functions of lipids in the body are:

Membranes: The glycerophospholipids are the main structural component of biological membranes, such as the cellular plasma membrane and the intracellular membranes of organelles.

Energy storage: Triacylglycerols, stored in adipose tissue, are a major form of energy storage.

Signaling: Lipid signaling may occur via activation of G protein-coupled or nuclear receptors identified as signaling molecules and cellular messengers.

Lipids help regulate important cellular processes such as cell proliferation and immune response. Problems with lipid signalling have been linked with a number of diseases including cancer, diabetes, autoimmune diseases, and inflammatory conditions. “Lipid molecules on cell membranes can act as switches that turn on or off protein-protein interactions affecting all cellular processes, including those associated with disease.”

Biosensor for lipid levels using modified proteins to fluoresce
Wonhwa Cho, a chemistry professor at the University of Illinois at Chicago developed a biosensor using modified proteins to fluoresce and act as sensors for lipid levels. The technique allows quantification by using a hybrid protein molecule that fluoresces only when it binds specific lipids.

He worked with a lipid known as PIP2 — an important fat molecule involved in many cellular processes. The sensor binds to PIP2 and gives a clear signal that can be quantified through a fluorescent microscope. This results in the quantification of membrane lipids in a living cell in real time. The protein was engineered in such a way that it became very stable, behave well, and specifically recognize a particular lipid.  Cho now plans to create a tool kit of biosensors to quantify most of the lipids.

He said: “We’d like to be able to measure multiple lipids, simultaneously. It would give us a snapshot of all the processes being regulated by the different lipids inside a cell.”

The quantification of lipid molecules utilizing the fluorescent proteins looks like a significant development.  We hope to see applications/ products like biosensors based on the research.

Ultrasound-based diagnostic imaging technique used for visualizing subcutaneous body structures including tendons, muscles, joints, vessels and internal organs for possible pathology or lesions. Obstetric sonography is commonly used during pregnancy and is widely recognized by the public. MobiSante show cased its mobile based ultrasound device in Mobile Health Expo in late 2010. Food and Drug Administration (FDA) approved its ultrasound gadget named MobiUS SP1.

Ultrasound Machine
An ultrasound machine is a medical equipment that uses probes that go either in the body or on the surface, and in the case of pregnancy, is used to get a clear picture of the fetus and its development in the womb. The frequencies used in diagnostic ultrasound typically between 2 and 18 MHz.

Smartphone-based ultrasound imaging system
MobiSante has launched smartphone-based ultrasound imaging system, MobiUS™ SP1. It has been cleared by the FDA, brings ultrasound imaging within reach of health care professionals everywhere at reduce costs.

It works on Windows Mobile 6.5-based Toshiba TG01 smartphone. Smartphone’s cellular and Wi-Fi connections can be used for sending images for consultation or storage in the PACS system, making it easy to keep a record of all images for reimbursements as well as benchmarking.

Other benefits

  • A rural OB/GYN can confirm pregnancy and detect common complications without sending patients to the centers.
  • GP can look for gall bladder, kidney stones and aneurysms while they are conducting regular physical exams of their patients.
  • Qualified Emergency Responders can use such devices to do simple diagnosis at the site of an accident.

Enhanced access to ultrasound imaging may create a bigger demand for the expertise of Radiologists back at the main healthcare center, reducing costs by enabling earlier and faster diagnosis. The recent trend has been development of handheld ultrasound machines by Giants like Philips, Toshiba, Siemens, etc to capture rural market of developing countries like India and China.  Device developed by MobiSante falls in the same realm and shows promise to be used as basic diagnostic tool at low cost.

Diabetes mellitus is a serious, life-threatening metabolic disorder. There is a need for monitoring blood glucose levels on a regular basis in such patients. A device that allows accurate glucose monitoring in real time without the use of frequent finger sticks, will render a reliable, less invasive method for continuous glucose monitoring. This could facilitate strict blood glucose control, facilitating safer self-management and improved long-term health benefits through improved maintenance of normoglycemia. It helps to achieve euglycemia while avoiding severe hypoglycemic events in their patients.

Symphony Transdermal Continuous Glucose Monitoring System
Echo Therapeutics, has achieved positive results from a clinical feasibility study of its Symphony transdermal continuous glucose monitoring therapy. The system comprises of a wireless  glucometer and a transdermal permeation system called the Prelude.

The accuracy of the monitoring device was compared with reference samples from a bench top blood glucose analyzer. Venous reference samples were taken via intravenous lines every 15 minutes, over the course of the 24 hour study period. No adverse effects were noted after 24 hours and a high level of correlation was observed between the Symphony monitor and the bench top analyzer.

Using over 1,600 Symphony tCGM glucose readings from the 12 study subjects paired with reference blood glucose measurements, CG-EGA showed that 98.3% of the readings were clinically accurate, There were no adverse events reported from the Prelude skin permeation or the Symphony tCGM biosensor.

I am sure you have had your routine eye exam and have gone through retinal exam by dilating the pupil.  I remember once, I had gone through dilation of pupil and was driving back home with the special goggles provided by the physician.  I did not realize, until I started driving, that my vision will be affect to a great extent and somehow made it to home. It is more tough for the children, who have trouble in understanding the cause of blurred vision.  Weel, i-Optics came up with a retinal imaging system that would not require dilation of pupil.

What is role of retina?
The retina is located in the back of the eye and functions in the same way as a film in a camera. As light enters the eye, it is focused on the retina. This visual information is sent directly from the retina to the brain and helps us to see the images.

The retina has blood vessels which can be seen by the optometrist by looking into the eye. This allows the doctor to diagnose and manage the conditions of diabetes, high BP, retinal detachments, glaucoma etc. Digital technology has made it possible to capture the images to be stored or printed so that further investigations and treatments can be carried out over the time. This is retinal imaging.

 Why is pupil dilated for eye exam?
Dilation of pupil enables an eye care professional to see more of the retina, the light sensitive layer of tissue at the back of the eye. Dilating (widening) the pupil permits the retina to be examined for signs of disease. To do this, drops are placed into the eye to dilate the pupil. After the examination, vision may remain blurred and the patient may be bothered by the brightness of the sun for a few hours.

What advantage does Retina Imaging System offer?
A new retinal imaging system was developed by i-Optics, a Netherlands based company.  i-Optics utilized scanning laser ophthalmoscope technology to detect early eye pathology. The advantage offered by i-optics include:

  • pupil dilation is not required, laser technology provides  capability to image through pupils as small as 2 mm.
  • waiting time is reduces prior to the exam as a results and recovery time does not include blurred vision before driving home.
  • provides a better contrast than regular fundus cameras and can penetrate media opacities such as cataract and corneal irregularities.

How does Retina Imaging System work without dilation?
i-Optics has named the device as EasyScan, utilizing as narrow laser beam to scan the surface of the retina. The reflected light is captured by a detector, thereby creating a real-time image on the monitor.  EasyScan is based on SLO technology, which brings out clinical features in the retina in the earliest stages, provides better contrast than fundus cameras, and can better penetrate media opacities such as cataract and corneal opacities.It supports three imaging modalities: green (532 nm), near infrared (785 nm), and those two combined.

EasyScan has following features:

  • Images can be previewed live with a freeze option on the computer screen.
  • The system  facilitates  many automated features like eye steering, iris detection, and focusing.
  • It connects to a PC or laptop via a standard USB connection which also functions as its power supply, so AC power is not required.
  • Pictures can be stored and shared in different formats like: DCM, TIFF, TIF, JPEG, BMP. The device can easily be controlled by a joystick.

Catheter patency device provides a constant velocity of fluid in the catheter upon disconnection of a luer. The positive displacement feature prevents the backflow of blood into the catheter lumen which can otherwise lead to thrombotic occlusions. It helps maintain the patency of vascular access devices and permits the use of saline flush for any vascular access device, including central venous access.

Catheter patency device is essentially required due to the following:

  • Fibrin formation being a host to catheter related bloodstream infection, it reduces fibrin formation.
  • It prevents blood reflux into the catheter lumen which can otherwise lead to thrombotic catheter occlusion.
  • Flushs the catheter with normal saline and eliminate the risk of Heparin Induced Thrombocytopenia.

 ICU Medical Launches Neutron needlefree catheter patency device
ICU Medical has launched the Neutron needlefree catheter patency device with constant neutral pressure. It has an IV catheter connector that prevents reflux of blood and thus maintains catheter patency and prevents other complications such as biofilm formation.

The FDA cleared device that prevents reflux during situations such as IV bag run-dry, infusion pump stop or patient vascular pressure changes caused by coughing, sneezing or movement. A silicon seal forms a barrier when the line is not being used. During access, the seal is depressed and the fluid path windows are exposed through the device’s split-septum.

It is claimed by ICU Medical that Neutron needle free catheter patency device with constant neutral pressure is the world’s first and only FDA-cleared device that can significantly reduce all types of reflux into a catheter.

A syringe infusion pump infuses fluids, medication or nutrients into a patient’s circulatory system. It is generally used intravenously. Subcutaneous, arterial and epidural infusions are occasionally used. Smith Medical got approval from FDA on their new wireless syringe infusion pump.

Infusion pumps can administer fluids in ways that would be impractically expensive or unreliable, if performed manually by nursing staff. For example, they can administer as little as 0.1 mL per hour injections (too small for a drip), injections every minute, injections with repeated boluses requested by the patient, up to maximum number per hour (e.g. in patient-controlled analgesia), or fluids whose volumes vary by the time of day.

Due to their ability of producing quite high but controlled pressures, they can inject controlled amounts of fluids subcutaneously (beneath the skin), or epidurally (just within the surface of the central nervous system- a very popular local spinal anesthesia for childbirth).

New Generation Wireless Syringe Infusion Pump
Smiths Medical, a leading global medical device manufacturer received clearance from the U.S. Food and Drug Administration (FDA) for its new Medfusion® 4000 wireless syringe infusion pump with the PharmGuard® infusion management software suite. The new customizable system, which helps prevent medication errors, will allow health care providers to send and receive medication delivery information more efficiently.

It is the next-generation advancement of the Medfusion® 3500 syringe infusion pump, which is widely recognized for its accurate medication delivery to patients in critical care units, including neonatal and pediatric intensive care.

This upgraded version runs on Smiths’ proprietary PharmGuard software that allows easy management of infusion data and provides safety parameters to prevent incorrect dosing during anesthesia or in critical care areas. The new model provides wireless connectivity (802.11b/g), so that pump data can be managed remotely without having another wire in the OR.

It has wired Ethernet connectivity for efficient drug library, syringe and firmware management, eliminating the need to physically search for pumps and manually update them. The software is a scalable and upgradeable web-based application that enables the wireless collection, management, and Continuous Quality Improvement (CQI) reporting of patient infusion data to track trends in compliance with medication dosing and clinical best practices.
