Patient Recovering from First US Penis Transplant

A Massachusetts man is recovering from the United States’ first penis transplant, and doctors in Boston say they are “cautiously optimistic” he will make a full recovery.

Sixty-four-year-old Thomas Manning lost his penis to cancer in 2012 and was given a new one last week thanks to an anonymous dead donor.

Manning said he wanted to go public about his surgery, which took 15 hours, to encourage others who may be ashamed or humiliated by the loss of a sex organ.

If all goes well, doctors say Manning will regain full urinary and sexual functions. They also say they want to ensure the operation is a success before they perform it on others, including wounded soldiers.

The world’s first successful penis transplant was undertaken last year in South Africa.

It was tried in China about 10 years ago, but the patient asked doctors to remove the organ because he and his wife had psychological problems.

Manning’s doctors at Massachusetts General Hospital said his psychological state will play a big role in his recovery.

Emotionally, he’s doing amazing,” Dr. Curtis Cetrulo told a news conference Monday. “I’m really impressed with how he’s handling things. … He wants to be whole again. He does not want to be in the shadows.”

The Boston Herald reported that Cetrulo was among the lead surgeons on a team of more than 50. (Voice of America)

Science is now closer than ever to Pig-Human Organ Transplants

The experiments stem from the fact that humans share a lot of DNA with mammals

August 12, 2017: There’s a word that everybody should learn because in a few years it may be in almost every day use, as scientists come closer to the Pig-Humans Organ Transplants.

According to scientists at Harvard University, advances in research of xenotransplantation, or transplantation of animal organs to humans, promises to bridge the huge gap between the number of human organs available for transplants and the number of patients on waiting lists.

The experiments stem from the fact that humans share a lot of DNA with mammals, specifically pigs. Pig heart valves are already being routinely transplanted into humans, some diabetes patients have transplanted pig pancreas cells and pig skin is often used for treating patients with severe burns.

Combining gene editing technique called CRISPR with cloning, Harvard scientists created piglets that do not harbor viruses harmful to humans. This, they say, may lead to the first direct xenotransplantation within as little as two years.

Such patients would still be required to take anti-rejection drugs so the ultimate goal is to grow pigs with human ready organs that don’t require any medication.

Other scientists express skepticism saying a lot more research is needed before xenotransplantation becomes widely available.

New York, May 1, 2017: A computer-driven automated drill that could perform a type of complex cranial surgery 50 times faster — decreasing the operating time from two hours to 2.5 minutes — has been developed by researchers, including one of the Indian-origin.

A translabyrinthine surgery is performed to expose slow-growing, benign tumours that form around the auditory nerves.

For such complex surgeries, surgeons typically use hand drills to make intricate openings, adding hours to a procedure and may also increase the risks of loss of facial movement.

However, the new automated machine replaces hand drills to produce fast, clean, and safe cuts, reducing the time the wound is open and the patient is anesthetised, thereby decreasing the incidence of infection, human error, and surgical cost.

“I was interested in developing a low-cost drill that could do a lot of the grunt work to reduce surgeon fatigue,” said A.K. Balaji, Associate Professor at the University of Utah in the US.

The drill, which could play a pivotal role in future surgical procedures like hip implants, was developed from scratch to meet the needs of the neurosurgical unit, as well as developed software that sets a safe cutting path, the researchers said in the paper reported in the journal Neurosurgical Focus.

First, the patient is imaged using a CT scan to gather bone data and identify the exact location of sensitive structures, such as nerves and major veins and arteries that must be avoided. Surgeons use this information to programme the cutting path of the drill.

In addition, the surgeon can programme safety barriers along the cutting path within 1 mm of sensitive structures.

If the drill gets too close to the facial nerve and irritation is monitored during surgery, the drill automatically turns off. (IANS)
