Use your cell phone to diagnose diseases.


Microscopy provides a simple, cost-effective, and vital method for the diagnosis and screening of hematologic and infectious diseases.It is an essential tool in disease diagnosis and widely used all over the world. Unfortunately, the EXPERTISE required to use the tool, and to evaluate the findings is not very common. One requires a pathologist with many years of experience to make sense of those seemingly random and confused pixels. ( I know, i am a pathologist :-)

But the advent of digital imaging has solved many of our troubles. Telepathology made sure that we do not need a pathologist physically present at the site, to render a diagnosis. But microscopy and digital imaging of the biopsy/tissue fragment was still a hassle. Now we have done better. You don’t even need a microscope to send a microscopic image over the network!!Researchers from the Univ. of California worked with high-powered LED – which retails for just a few dollars – coupled with a typical camera phone to produce a clinical quality image sufficient for detecting in a field setting some of the most common diseases in the developing world.

The newly developed technology, CellScope, allows for average cell cameras to be retrofitted with powerful microscopes, able to detect malaria parasites, and even fluorescent marker-stained tuberculosis bacteria.Thus you have your humble cell-phone transformed into the “cell-scope”.

“The images can either be analyzed on site or wirelessly transmitted to clinical centers for remote diagnosis. The system could be used to help provide early warning of outbreaks by shortening the time needed to screen, diagnose and treat infectious diseases,” University of California in San Francisco (UCSF)/UCB Bioengineering Graduate Group graduate student David Breslauer adds

HIPAA compliant mobile consultations for Doctors



Finally, a commercially available intelligent system to allow all physicians to provide consultations from anywhere, simply through a Blackberry ( or any other smartphone, but not an iphone !?! See Comment 1).

The mVisum Medical Communication System is a communication tool that allows medical professionals to securely receive, review and respond to patient data recorded at the point of care.

Security-
mVisum uses multiple levels of security and authentication to ensure HIPAA compliance. The handheld requires unique username and password for each physician, which is then authenticated by the server against the IMEI number and phone number. Data transmission between the server and the handheld is carried out through a patented double encryption system, where the data is first scrambled, which is further delivered through a 128 bit encrypted pipeline, each step individually meeting or surpassing HIPPA requirements. The sending console to server communication is also similarly architected, thus providing strong security end-to-end.

Types of Data Transferred include-

  • DICOM Images – loss-less representation of the original file, with Zoom capabilities.
  • CT Scan
  • MRI
  • EKG
  • Cine Loops
  • X-Rays
  • Free text

The system has advanced technology that allows the system to be availability aware,so that another physician can immediately be contacted if the original intended physician is unavailable.Once received, the physician can review data and securely respond with medical opinion, prescription or other critical orders. Real Neat, eh?

Medical consultation on the Move


A new mobile handheld technology developed by mVisum of Cedar Brook, NJ, is been tested. This communication tool boasts of providing off-site cardiologists access to EKGs that can then be used to prescribe immediate treatment.

The Department of Veterans Affairs is testing this new system which seemingly enables fast transfer of clinical data to a smartphone for review within minutes. The mVisum Medical Communication System is stated to be a communication tool which permits health-care personnel to securely receive, review and respond to a patient”s medical data recorded at the point of care. This transfer of information notably takes place through secure HIPAA compliant internet servers, later transmitting it via mobile technology to the smartphone of the physician. More so, this system is also loaded with the ability to be availability aware, so that the patient can refer to another physician in the absence of the original intended physician. The various types of medical data that can be sent through this technique include DICOM images, EKGs, CT scans, MRIs, X-rays, etc. Along with this, textual information relating to the patient may also be included in the message for the purpose of getting a broader idea about the condition of the patient.

View more news videos at: http://www.nbcwashington.com/video.

The process begins with the recording of patient data at the point of care. Point of Care can include the physician’s office, medical center, hospital, or anywhere the patient is located and an system is installed.Data is transmitted securely and reliably to the physician’s mobile handheld device. The system has advanced technology that allows the system to be availability aware,so that another physician can immediately be contacted if the original intended physician is unavailable.Once received, the physician can review data and securely respond with medical opinion, prescription or other critical orders.

It takes a lot of effort, and money to train a pathologist, equip him/her with all the instruments required, and then use the skills in a backward area without proper facilities.

CellScope could also provide remote access to digitized health records, and would be amenable to epidemiological studies, using triangulation or global positioning system location data, such that outbreaks could be monitored as they happen.

So maybe i could click a photomicrograph of that mole on my friend”s forearm, twitter it to my onco-pathologist friends, who view it on their smartphones and twitter / message their diagnosis back to me. Simple and fast, especially with my own group of pathologists on the network.

Basics of Cerebrovascular accidents


Legendary CBS newscaster Walter Cronkite, who many referred to as “Uncle Walt,” has passed away, CBS News reports. He was 92 years old. As the CBS anchorman for almost 20 years, he was one of the most trusted faces in the American media. Reports say that he died due to a “cerebro-vascular accident” (also called Stroke) without specifying the exact pathology.

A stroke occurs when the blood supply to the brain is disturbed in some way. As a result, brain cells are starved of oxygen. This causes some cells to die and leaves other cells damaged. Most strokes happen when a blood clot blocks one of the arteries (blood vessels) that carry blood to the brain. This type of stroke is called an ischaemic stroke. Cerebral hemorrhage is when a blood vessel bursts inside the brain and bleeds (hemorrhages). With a hemorrhagic stroke, blood seeps into the brain tissue and causes extra damage.

  • Smokers
  • Irregular heart beat (atrial fibrillation)
  • Diabetes

Early diagnosis and treatment is the key to decreasing mortality due to a stroke. A transient ischemic attack (known as a TIA or ministroke) is similar to a stroke except that, with a TIA, the symptoms go away completely within 24 hours. People who have a TIA are very likely to have a stroke in the near future.

The most common early signs of a CVA are:

  • weakness down one side of the body, ranging from numbness to paralysis that can affect the arm and leg. Often, the weakness starts at a focal point and increases over the next few hours as the hemorrhage increases.
  • weakness down one side of the face, causing the mouth to droop. Speech may become slurry and swallowing becomes difficult.
  • severe headache and sudden loss of vision.
  • confusion, vomiting and loss of balance.

The World Health Organization estimates that 15 million people suffer a stroke worldwide each year, resulting in 5 million deaths and 5 million people permanently disabled.Stroke can occur in patients of all ages, including children. The Risk of stroke increases with age, especially in patients older than 64 years, in whom 75% of all strokes occur. Many people recover completely after a stroke. For others, it can take many months to recover from a stroke. Physical therapy and other retraining methods are greatly improving rehabilitation and recovery.

Use of Forensic animations


Bose–Einstein condensate In the July 14, 1995 ...

.O {font-size:149%;}

The law review literature is full of clichés such as “A picture is worth a thousand words” . Be it the judge or a Jury, it is very difficult to explain certain scientific and medical aspects by simple oral description. Technology of 3D animations is now freely available and can be used to explain many complicated medical and scientific arguments.Though animations have been around for many decades, its use in forensics started only by late 1980″s.

By 1992, it was estimated that computer- generated displays had been used in 858 cases in the US where litigation took place between major companies. In these, all except 15 settled out of court and in all the 15 cases which went to trial, the side using computer-generated displays was successful. Thus it is very apparent that use of scientifically created animations can go a long way in winning legal cases.

It has been reported that the first instance of computer-generated graphics being used in a British court took place at Oxford Crown Court in September 1994. There is yet no famous case of use of Animations in Indian courts. Animations can be used for demonstrative evidence, and the admissibility of animations in courts have been clearly expressed by the British courts. The following presentation takes an overview of animations used in Forensic sciences. To find out how you can use Animations in India, contact us at info@markivmedical.com, and visit us at Mark IV Studios, Coimbatore, India.

Prozac- Things to know before you use it.


Fluoxetine HCl 20mg Capsules (Prozac)

Prozac ( or Fluoxetine Hydrochloride ) is a commonly used antidepressant in clinical practice. Fluoxetine has been approved by the FDA for the treatment of major depression, obsessive compulsive disorder, bulimia nervosa and panic disorder. Used since mid-1970a, Eli Lilly’s patent on Prozac (fluoxetine) expired in August, 2001, prompting an influx of generic drugs onto the market. It has shown excellent results and is often used by people/patients even without proper prescriptions. The use , and abuse of Prozac has reached phenomenal proportions.Is Prozac safe?? What are the few things you must know before you start using it?

Below is a slideshow i have prepared detailing a few important facts about Prozac use. Also incorporated is a video which will further enhance comprehension about this widely used drug.

Scientic animations awards ceremony, China


Location of Guiyang in Guizhou ProvinceImage via Wikipedia


The 1st Annual International Science Animation Awards being held August 8th 2009 in Guiyang China

Deadline for DVD submissions -

July 15th 2009

Guiyang, China (PRWEB) — Honoring the works of visual wonder that depict what science perceives beyond our eyes, The 1st Annual International Science Animation Awards (ISAA) are being presented in Guiyang, China August 8th 2009.

The ISAA “Sci-An” will be awarded for 2D and 3D works that demonstrate both the highest achievements in scientific and medical communication and superb attention to aesthetic, creative and technical presentation.


This is an industry that will grow exponentially with the compounding demands from various science sectors in the years ahead

This year marks the first in what will be an annual juried salon, bringing together in China the work of scientific animators from around the world. Professional and student work is welcome, and will be judged separately.

The event will include presentations and panels with industry leaders from across Asia, the United States and Europe.

The two judging categories are commercial and educational, in short form of under three minutes’ run time. Long form work and compilations from longer projects may be entered and will be evaluated separately.

“The need for recognition in this dynamic emerging field has grown to the point of launching this inaugural event” said founding co-chairman, Sander Johnson, who with founding co-chair, David Bolinsky initiated the concept for this international forum at last year’s Guiyang Animation Festival, in Guiyang, China. That festival is the launch for this year’s Sci-An Awards, which will next year become an independent event.

“Hosting this unique forum and awards ceremony in China truly invites pan-Asian and East-West interaction with leaders in the industries and major universities” said Bolinsky, a leading American creator of 3D scientific animation for Harvard University Medical, the Smithsonian, most major pharmaceutical companies, NOVA and additional broadcast clients. “And it promotes further advances in these various industries of science and animation”.

ISAA General Secretary, Liuyi Wang, founding Director of China’s Asian Youth Animation & Comics Contest sees great benefit in highlighting achievements in these advanced new fields of science animation as 21st Century career paths for talented young computer animators. “This is an industry that will grow exponentially with the compounding demands from various science sectors in the years ahead” said Wang.

ISAA “Sci-An” Awards will be given to first, second and third place, plus awards of merit and best in show. The judges this year will include David Bolinsky, XVIVO Scientific Animation Partner; Jane Hurd, Hurd Studios Founder; and Elizabeth Rega, chief anatomical consultant Walt Disney Feature Animation and SONY Pictures Imageworks, with prominent Asia judges to be announced soon.

Deadline for submission is July 15th 2009 and entries cannot be returned.

In welcoming all applications; there are no entry fees required with submissions.

Applications can be downloaded from www.ayacc.org/Sci-Ansubmissionform

Physiology of Propofol in drug Abuse


Is Propofol, or Diprivan what Michael Jackson Used for ( Drug) Abuse ?

According to Cherilyn Lee, a registered nurse who operates a Los Angeles-based nutritional counseling business, in California, “Jackson was complaining of insomnia and pleaded for her to get him some (Diprivan)”. Other reports claim Propofol was recovered from his residence. This conversation reportedly occurred in April of this year. Preliminary reports say that M.J died of cardiac arrest, which is within the possible effects of unmonitored Diprivan use. (A rapid bolus injection can result in undesirable cardiorespiratory depression including hypotension, apnea, airway obstruction, and oxygen desaturation.)

Diprivan is a general anesthetic, used to start or maintain anesthesia during certain surgeries, tests, or procedures. It is available in a white vial of 20, 50 and 100 ml (containing 10mg/ml.).Most adults require 2 to 2.5 mg/kg of the drug ( approx. 10 ml). DIPRIVAN Injectable Emulsion is an IV sedative-hypnotic agent and can cause potentiation of other narcotic drugs and benzodiazepines when used together. The most common side-effects include Change in mood or emotions; dizziness; drowsiness; lack of coordination. It is given intravenously, usually within the operation theater or in a clinic. It has a rapid onset of action ( less than 1 min) and short duration of action (approximately 10 min but is dose dependent).It has direct cardiodepressant effects, leading to decreased blood pressure and heart rate in higher doses. Its actions causing decreased heart rate and respiratory rate mean that use of propofol is done only under continuous monitoring of vital signs.Diprivan is not meant for use in pediatrics and elderly population since its safety has not been established in these populations. Prolonged use of propofol results in accumulation of the drug in body tissue and increases the duration of action as well as chances of overdose.

Rarely, Cases of death due to propofol have been discussed in medical literature. All these cases have occured in hospital settings only.It is definitely not meant for home use and this is the first time I have heard of Diprivan being used as a drug of abuse outside hospital settings.

Euphoria, sexual hallucinations and disinhibition have been described on recovery of propofol anaesthesia. These effects could explain the recreational use of the drug. Moreover, several experimental studies strongly suggest the potential for abuse and dependence on propofol,and few cases of abuse and dependency have been described, mostly in medical professionals. As propofol is generally not recognized as a substance of abuse, and because of its safe profile, it is important to remember that rare adverse reactions of propofol could produce death in a context of abuse, even at therapeutic dose range, in the absence of ventilatory and medical assistance.
