Using Cellphones to diagnose Malaria and Blood disorders

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 :-)


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. 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 sherlockian "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. 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.

Kindle in Medicine




 Kindle is a new device that is changing the face of reading. The best of the current lot of e-book readers, Kindle is a boon for   medical students and professionals, allowing them access to hundreds of books on the go!. The basic functions of Kindle can be seen here.Kindle, now in its third avatar, the Kindle Dx (Deluxe) boasts of more advanced features, like PDF support (experimental)  , longer battery life, 5-way Controller and sleeker design.

Check out more features here.. You can view it from all angles, zoom into any area and look at its features.

Using Kindle in Medicine

  • Easy for medical students to keep up with all their scheduled reading. You can download and read reference materials that you have read previously to refresh your memory.You can seek out new textbooks to look for answers too.
  • Seeking out symptoms, conditions, and other relevant information is easy.You can view photos on the Kindle if you need to see pictures of various signs and symptoms conditions. 
  • Study medical texts and highlight portions of texts / make notes on the Kindle as you go. Zoom into images for micro details.Bookmark and annotate important portions.
  • Research can be done on its built-in web browser ( experimental feature) , no need to carry a laptop to access the internet.It offers free Wireless access to Wikipedia
  • .Multiple books can be read at once, no need to carry a JUMBO Grey"s anatomy or Robbin"s Pathology encyclopedias !! It boasts of storage capacity of 1500 / 3500 books, depending on the Model.
  • You can listen to music while you read.
  • Inbuilt Text-to-Speech feature lets you listen to your favorite books.
It has a clear policy for returning the instrument or any content bought ( within 7 days of purchase) and also One year limited warranty. The kindle library boasts of more than 300,000 books for download, and many more added regularly. Priced at 300 and 500 $$ , and weighing approx. 300 and 500 grams (depending on the model) it is still too pricey for open embracing of this technology. Some libraries have started lending out Kindles ( with preloaded content) to its patrons.

Personally speaking , i can see a lot of content being adapted for Kindle, provided the machine becomes less expensive.
Also , many more wireless features ( like chat, email, videos etc) need to be added. If more such functionality is added to justify its high prices, i expect a LARGE number of medical students turning to Kindle.

New Swine Flu Guidelines

On 14 th august, Friday night, after facing flake for the past two weeks on the bungled handling of Swine Flu epidemic in India, the government has come up with a better set of guidelines.The new guidelines allow ALL doctors to treat for Swine Flu ( earlier only designated hospitals and doctors could treat Swine flu!!)The guidelines were finalized after a five-hour meeting chaired by Health and Family Welfare Minister Ghulam Nabi Azad.

The patients have been categorized as follows:

  • Category A: Patients with mild fever plus cough/sore throat with or without body ache, headache, diarrhoea and vomiting. They do not require Oseltamivir and should be treated for the symptoms mentioned above. The patients should be monitored for their progress and reassessed after 24 to 48 hours by the doctor. No testing of the patient for H1N1 is required. Patients should confine themselves at home and avoid mixing with the public and high risk members in the family.( I agree with this)

  • Category B: (i) In addition to all the signs and symptoms of Category A, if the patient has high grade fever and severe sore throat, he/she may require home isolation and Oseltamivir; (ii) In addition to all the signs and symptoms of Category A, individuals having one or more of the following high risk conditions shall be treated with Oseltamivir: children under five, pregnant women, those above 65 years, those with lung diseases, heart disease, liver disease, kidney disease, blood disorders, diabetes, neurological disorders, cancer and HIV/AIDS; Patients on long term cortisone therapy. No H1N1 tests are required for Category-B (i) and (ii). Such patients should confine themselves at home and avoid mixing with the public and high-risk members in the family.( I think all such cases be tested for H1N1, and antiviral therapy started without delay)

  • Category C: In addition to the symptoms of Categories A and B, if the patient has one or more of the following: breathlessness, chest pain, drowsiness, fall in blood pressure, sputum mixed with blood, bluish discolouration of nails; irritability among small children, refusal to accept feed; worsening of underlying chronic conditions. Such patients require testing, immediate hospitalisation and treatment.( All such patients should be started on antivirals without even waiting for test results!!, its already late!!)



During the meeting, various guidelines and protocols developed by the World Health Organisation, Geneva, the Centre for Disease Prevention and Control, Atlanta, United States, and the National Health Service, United Kingdom, were also discusse
