Control group for ultrasound scan
Prader-Willi Syndrome (PWS) is a congenital genetical disease characterized by moderate retardation, food-seeking behavior and a serious risk of developing health threatening overweight, low stature, abnormal body composition and a lack of growth- and sex-hormones. They can not live an independent life and are reliant of help from care personnel.
People with PWS react abnormally to signals from their own bodies. E.g. they have a reduced sense of pain and can have a lacking urge to urination despite a full bladder. Most of the patients also have a relatively slow pulse, which can be consistent with a dysfunction in the nervous system (the parasympathetic nervous system) which also has large significance for the bladder- and bowel function.
The Intestinal function in people with PWS is a sparse described subject, which has not been systematically examined in scientific context. We therefore want to examine whether the bowel function in people with PWS are different from the bowel function in healthy people.
The subject is elucidated by a medical examination, a questionnaire, a registration of toilet habits, a measurement of the rectal diameter by an ultrasound scan and a measurement of the colonic transit time.
The results will be compared to findings in normal healthy people. Because no normal material exists for rectal diameter measured by ultrasound, we will establish one.
The result of the project will increase our knowledge of possible bowel dysfunctions such as constipation, in people with PWS and can immediately lead to improved care for and optimized treatment of the patients.
