Vatican Children’s Hospital Carries Out A Pioneering Surgery On a 30-month-old

Surgeons performing a laparoscopy have an extremely detailed picture of the patient's anatomy, allowing more precise incisions with a lower risk of bleeding.

Surgeons at the Vatican children’s hospital in Rome have carried out a pioneering surgery in which a Lebanese woman’s kidney and part of her liver were transplanted in her 30-month-old son, who suffers from a rare metabolic disorder.

Doctors at the Bambin Gesu hospital performed path-breaking laparoscopic surgery on the left side of the woman’s liver and on her kidney.

The boy, named Danil, suffers from primary hyperoxaluria, a severe form of a rare metabolic disease called oxalosis, characterised by the formation of calcium oxalate deposits in organs and tissues.

Oxalosis can cause urinary infections and permanent kidney damage, and in the most severe cases, can stunt the patient’s growth and cause brittle bones that are vulnerable to fractures. It affects one in 100,000-333,000 people.

“This operation could be the first of its kind in the world,” the Bambin Gesu said in a statement.

“We are not aware of previous cases in which laparoscopic surgery has been carried out to transplant the same donor’s liver and kidney one after the other.”

The team at the Bambin Gesu that carried out the laparoscopic transplant in Danil of part his mother’s liver was led by Marco Spada, while the transplant of her kidney to the toddler was spearheaded by Luca dello Strologo.

Laparoscopic surgery to transplant a kidney from a living donor to a recipient is well-established, while the use of the minimally invasive technique for liver transplants is a more recent operation that is only done in the most specialist centres and, in Italy, currently only at the Bambin Gesu.

All such patients treated at the Bambin Gesu have had dialysis during surgery and several days afterwards, and all the operations have been successful, according to the hospital. In the past 24 months, it has performed 32 liver or kidney transplants from living donors and 98 from deceased donors.

The advantages of laparoscopy include a significant reduction in surgical trauma which reduces the length of time patients need to spend in hospital, less need for painkilling drugs, a lower risk of postoperative complications and a more rapid return to normal life, according to the experts.

And thanks to high-resolution (3K and 4K) and three-dimensional imaging technology, surgeons performing a laparoscopy have an extremely detailed picture of the patient’s anatomy, allowing more precise incisions with a lower risk of bleeding. (IANS)

A Comprehensive Study Of Parasitic Worms Release Numerous Anwers

The analysis found almost a million new genes that had not been seen before, belonging to thousands of new gene families, and identified many new potential drug targets and drugs.

The largest study to date of the genetic makeup of parasitic worms has found hundreds of new clues about how they invade the human body, evade its immune system and cause disease.

The results point to potential de-worming treatments to help fight some of the most neglected tropical diseases — including river blindness, schistosomiasis and hookworm disease — which affect around a billion people worldwide.

“Parasitic worms are some of our oldest foes and have evolved over millions of years to be expert manipulators of the human immune system,” said Makedonka Mitreva of Washington University’s McDonnell Genome Institute, who co-led the work with colleagues from Britain’s Wellcome Sanger Institute and Edinburgh University.

She said the results of this study would lead to both a deeper knowledge of the biology of parasites and a better understanding of how human immune systems can be harnessed or controlled.

Parasitic worm infections can last many years and can cause severe pain, physical disabilities, retarded development in children and social stigma linked to deformity.

Current medicines to combat them — including drugs made by Sanofi, GSK and Johnson & Johnson — can be moderately effective and are often donated by drugmakers or sold at reduced prices to those who need them. But the spectrum of drugs to treat worm infections is still limited.

To try to improve the potential drug pipeline and to understand how worms invade and take up residence inside humans and other animals, the research team compared the genomes of 81 species of roundworms and flatworms, including 45 that had never previously had their genomes sequenced.

“We focused our search by looking at existing drugs for human illnesses,” said the Sanger Institute’s Avril Coghlan, who worked on the team. She said this offered a possible fast-track route “to pinpointing existing drugs that could be repurposed for deworming.”

The study’s findings were published Monday in the journal Nature Genetics. (VOA)
