New Delhi, Nov 26, 2016: In a rare surgery, doctors at city-based Safdarjung Hospital on Friday cured a teenager with severe ligament avulsion fracture through mere stitches instead of using any implant like screws or endo button, doctors said.

According to the doctors, the other advantages of such surgeries is that such techniques bring down the cost by 70-80 per cent.

NewsGram brings to you latest new stories in India.

The unique surgery, which has been adopted by a few nations such as Germany and US, was performed by a team of doctors lead by Balvinder Singh, an Assistant Professor of Orthopaedics at Safdarjung Hospital.

According to Singh, 18-year old Ankur was unable to walk and bed-ridden for the last three weeks after meeting with an accident and suffered from posterior cruciate ligament avulsion fracture.

Posterior cruciate ligament (PCL) avulsion fractures are a type of avulsion fracture of the knee that represent the most common isolated PCL lesion. This typically involves separation of the posterior tibial insertion of the PCL to variable degrees.

“Unlike open ortho surgeries till now, in this case we performed arthoscopic surgery and used stitches to treat the problem,” said Singh.

The laprascopic ortho surgery was performed on Friday and some of the other doctors included senior residents Taha Ahmed and Mohit Garg and anaesthetist Anshu Meena.

“The patient had come to us as a last resort and we chose to perform this unique surgery,” said Singh.

According to the doctors,A the open surgeries which cost the patient over Rs 1.5 lakh in private hospitals while more than Rs 50,000 in government hospitals can come down to Rs 10,000 if this surgery is adopted. (IANS)

From Radio Signals A Pill Could Tell About Gut Health And Help Doctors

A pill could soon radio signals from inside your gut to help doctors diagnose diseases from ulcers to cancer to inflammation, according to a new study.

Scientists have developed a small, swallowable capsule that mixes synthetic biology and electronics to detect bleeding in the digestive tract.

The system can be adapted for a wide range of medical, environmental and other uses, the researchers say.

The biological part of the pill uses bacteria engineered to glow when exposed to heme, the iron-containing molecule in blood.

The electronic side includes a tiny light detector, computer, chip, battery, and a transmitter that sends data to a cell phone or computer.

“A major challenge for sensing in the GI tract is, the space available for a device is very limited,” said Massachusetts Institute of Technology electrical engineer Phillip Nadeau.

Using very low-power electronics they designed, Nadeau and colleagues fit all the components into a capsule about 3 centimeters long by 1 centimeter wide.

It’s still a bit big to swallow. But Nadeau says with engineering work it can likely be made about a third that size.

The engineered bacteria are contained in chambers covered by a membrane that lets small molecules in but does not let the organisms out. The researchers say the bacteria can be engineered to die if they accidentally leak from the capsule. Or future models may just use the key enzymes, rather than whole bacteria.

In laboratory tests, the pill successfully distinguished pigs fed small amounts of blood from those not given blood. The capsule has not yet been tested on humans. The team aims to do so in the next year or two.

Since the components are all fairly cheap to manufacture, the researchers speculate that the cost would be in the range of tens to hundreds of dollars.

And they say the same platform could be used to detect markers of a range of illnesses. Or, it could be used to sense chemicals in the environment.

“It’s really exciting, and I think it’s got a lot of legs,” said Rice University bioengineer Jeff Tabor, who was not part of the research team.

But Tabor notes that the sensors may need to be much more sensitive than what was used in the pig tests. He says there may be much less blood in the guts of actual patients than what the pigs were given. Other conditions may have the same limitations.

“For many actual diseases, you might have far less of the molecule that you need to sense available to you,” he added. (VOA)
