Researchers at the Sahlgrenska University Hospital in Göteborg have
managed to implant a blood vessel made from a patient’s own stem cells
in a ten year old, sick girl. One year after surgery she now is doing
pretty fine making the researchers to hope that this could be a method
to assist patients who need bypass surgery.
The process involves approach, in making the vein perform better
took three to four weeks, according to Michael Olausson, a professor at
the Transplantation Center at the hospital. The vein for the girl was
obtained from a donation from a deceased person, reports radio Sweden. “Then we have
removed all cells and all the genetic material, and after that we have
brought stem cells from the patient who will receive the blood vessel
and then grow this vessel out again,” says Michael Olausson, Professor
and Director of the Transplant Center at the Sahlgrenska University
Hospital in Gothenburg to radio Sweden.
At the moment, Michael Olausson and his team believe that the approach
could be of great help to many people with plug formation in their
blood vessels and that they need to undergo a so-called "bypass
surgery".
Asked how important is it that the patient's own stem cells are
included in the vein? Michael Olausson replied that it has to do with
the immune system recognizing the tissue as its own and thus will not
reject it. For him and the patient, it's a big advantage. All the
medications that are normally given to avoid the body rejecting the new
cell is very powerful and can cause side effects, so it is desirable to
avoid them.
He adds that this new method is also very important so that “we’ll be
able to solve problem around such things as hearts or kidneys in the
future. The next big step for us is probably a work around to get
arteries to function well. This opens the door and then maybe, be able
to produce whole organs,” says Michael Olausson.

With new methods, staff at the children healthcare centres in Sweden
has been able to carry out early detection of children with autism,
research carried out at Sahlgrenska Academy show.
In 2000, 0.16 per cent of all two year olds in Gothenburg were
diagnosed with some form of autistic disorder. In 2010 this had risen
to 0.8 percent. The increase is partly due to increased knowledge and
awareness of the signs of autistic disorder, which means that more
cases are detected.
A thesis made by Gudrun Nygren demonstrates how a combination of two
different methods can be used for early detection of disorders in the
screening of all 2.5 – year-olds in connection with the obligatory
visit to the child healthcare center (BVC).
“By combining methods, we have more sensitive and better tools for
early detection of various autistic disorders,” says Gudrun Nygren.
In one method the use of questionnaires and interviews with parents was
carried out in order to capture symptoms.
They may respond to 23 yes or no questions. In the other child health
clinic staffs are trained in observing the child’s ability to split
attention.
Surveys in Malmö last year also show the importance of early diagnosis.
The sooner the autistic disorders are detected the sooner a treatment
is given.
The methods have since 2010 been tested on about 5,000 children in
Gothenburg. It included autism screening into regular paediatric clinic
program of health monitoring in Gothenburg.
