    Abstract Growth hormone treatment for children with Prader Willi syndrome (PWS) has shown proven benefits not only in increasing final height but also with positive effects on body composition and motor development. In a recent letter to the editor, Hoybye and colleagues recommend growth hormone treatment for adults with PWS based exclusively on the genetic diagnosis and without regard for growth hormone secretory status. We question whether the benefits of growth hormone treatment in PWS adults, mainly improvement in body composition, are significant enough to justify the as yet unkown consequences of long-term treatment in an adult population. Morbidity and mortality in PWS are mainly due to complications of obesity, and growth hormone treatment does not result in a decrease in BMI or waist circumference. Increases in insulin-like factor-1 as a result of growth hormone treatment over the course of several decades in PWS adults raises concern over possible increase risk of cancer. Compliance with daily injections is likely to be poor. We suggest that efforts to provide appropriate dietary and exercise regimens may be more beneficial and cost-effective than advocating for growth hormone treatment for adults with PWS.

    Abstract Current published guidelines for routine care of women with Prader-Willi syndrome (PWS) do not include recommendations for gynecologic examinations. We describe our experience with gynecological examinations in women with PWS and offer recommendations for routine health care for these patients. Data were collected on all 41 PWS females ages ≥12 year, followed in our national Israeli multidisciplinary clinic between the years 2011 and 2022. Menstrual data and findings on external gynecological examination, including evaluation of the vulva and hymen were recorded at yearly visits. During the gynecological evaluation the topic of sexual education was discussed. Pelvic ultrasound, specifically for antral follicular count, was performed for those visiting the clinic during 2020-2022. Blood samples for luteinizing hormone (LH), follicular stimulating hormone (FSH), and estradiol were obtained routinely and DEXA scans for bone density were done when indicated. Of the 41 women, (median age at start of follow-up 17 years, range [12.3-39], BMI 30.4 kg/m

    Abstract To develop and examine the psychometric properties of the Home Program Evaluation Questionnaire (HoPE-Q), a novel tool designed to assess the effectiveness of home treatment programs for infants with hemiplegia. The HoPE-Q includes a pre- and a postintervention version and items that relate to Child's Function, Parents' Competence, and their Expectations and Satisfaction from the program. The research was performed in three stages. The first stage consisted of item construction and content validity, followed by the analyses of the tool's reliability and construct validity. The final stage involved the examination of the tool's sensitivity to determine its suitability as an outcome measure of the effectiveness of home programs for infants with hemiplegia. Results showed moderate-to-high internal consistency (α = 0.65-0.85) and high test-retest reliability in Child's Function and Parents' Competence (

    Abstract Aim: The present study aimed to investigate whether the response variability of infants to modified constraint-induced movement therapy and bimanual therapy are associated with different types of brain lesions.
    Method: Infants with unilateral cerebral palsy (N = 22) ages 8-15 months (mean = 10.95, standard deviation = 2.15 months) were grouped according to having either a periventricular brain lesion or a middle cerebral artery infarct lesion. Improvement in hand function was analyzed based on the mini-Assistive Hand Assessment results.
    Results: Infants with periventricular brain lesion displayed greater positive response to upper limb treatment compared to those with middle cerebral artery infarct ( P = .02). A significant difference in improvement according to type of treatment was found in the middle cerebral artery infarct group but not in the periventricular brain lesion.
    Conclusion: The present study showed an association between the type of brain lesion and the efficacy of upper limb treatment in infants. Infants with periventricular brain lesions displayed greater positive responses than those with middle cerebral artery infarct.

    Abstract Aim: The aim of the study was to characterize epilepsy, febrile seizures, electrographic features, and brain abnormalities in a large, national cohort of individuals with Prader-Willi syndrome (PWS).
    Method: This was an observational cohort study. Clinic charts of 126 individuals (63 males, 63 females) with genetically confirmed PWS (due to a deletion in 72 cases, to uniparental disomy [UPD] in 51 cases, and to an imprinting centre defect in two cases), aged from 1 month to 48 years (mean age 13y), were reviewed and 119 interviews conducted. Information regarding seizures, medication, imaging studies, and family history of seizures was collected. Ninety-five individuals (aged 1mo-48y) underwent electroencephalography (EEG).
    Results: Five individuals had epilepsy (4.0%), three of whom had major cerebral findings on imaging, and eight others had febrile seizures (6.4%). Of the three genetic abnormalities, deletion was associated with seizures. Focal epileptiform abnormalities were found in 12 out of 94 individuals, and five out of these 12 had a frank electrographic seizure pattern. Epileptogenic EEG abnormalities were associated with young age.
    Interpretation: The risk of epilepsy and febrile seizures in PWS is significantly lower than in Angelman syndrome and is associated with brain abnormalities. Electrographic seizures and focal epileptiform activity were present in 5% of individuals and were associated with young age. The underpinnings of epileptiform abnormalities in PWS and how they differ from those of the Angelman syndrome should be studied further.

    Abstract Many genetic disorders associated with intellectual disability are characterized by unique behavioral phenotypes which may have serious psychological consequences such as increasing the risk for sexual abuse (SA). Prader-Willi Syndrome (PWS), a severe neurogenetic syndrome with uncontrollable hyperphagia and high threshold for pain, is an excellent example of this issue. The absence of reports on SA in PWS highlights the lack of awareness to the topic. Our aim was to report on SA in individuals with PWS, describe its unique characteristics, and offer recommendations for its prevention. Caregivers of all individuals with genetically confirmed PWS living in the only two residential facilities designated for PWS in Israel were interviewed for a history of sexual behavior and abuse, and medical data were collected from their files. SA was reported in a quarter of the sample. In most of the cases (78%), food reward was used by the perpetrators to attract their victims. Age at SA ranged from 11 to 29 years. Most of the individuals did not disclose the event and some continued to initiate inappropriate sexual activity to obtain food. Characteristics unique to PWS, such as food-seeking behaviors and high threshold for pain, likely contribute to the risk for SA. These findings suggest that syndrome-specific programs for SA prevention should be considered for individuals with any genetic syndrome with behavioral problems that may increase SA risk.

    Abstract Hyperphagia leading to severe obesity with increased morbidity and mortality is the major manifestation of Prader-Willi syndrome. Caring for these individuals in a home environment is challenging and stressful for caregivers and families. Residential hostels specifically for PWS adults offer programs of diet, exercise, and vocational opportunities, but long-term effects of PWS hostel living have not been reported. We studied long-term changes in body mass index (BMI) for PWS adults living in residential hostels compared with age-matched controls living with families at home. The study included all 34 individuals (18 men) aged >17 years with genetically confirmed PWS living in residential hostels. BMI was recorded at the time of yearly clinic visits and compared to 23 PWS adults (10 men) living at home. BMI on entering the hostel was 36.3 ± 11.0 kg/m

    Abstract Background: Prader-Willi syndrome is a complex neurogenetic, multisystem disorder. Despite the variable endocrine abnormalities and hypothalamic-pituitary axis dysfunction, hyponatremia has been reported in only a few PWS patients. In previously reported PWS individuals, hyponatremia was associated with abnormal fluid intake or during desmopressin treatment.
    Case presentation: We describe an infant with Prader-Willi syndrome who had severe, prolonged asymptomatic hyponatremia without a history of excessive fluid intake or desmopressin treatment. We compare the findings with those of the few other reported cases and describe, for the first time, results of a hypertonic saline infusion test and studies of adrenal cortical function.
    Conclusion: Hyponatremia should be suspected in children with Prader-Willi syndrome, especially in infants with severe failure to thrive. Further studies are needed to determine the pathophysiology of hyponatremia in this syndrome.
