Introduction: Since 1960, enlarged polycystic ovaries associated with hypothyroidism, delayed bone age and precocious puberty are recognized as Van Wyk and Grumbach syndrome. Although it is rare entity, it should be considered in differential diagnosis of the enlarged polycystic ovaries.Case: An eleven-year-old girl was presented with sudden onset of abdominal pain and vomiting. A large mass with multiple cysts was seen ...

Background: The association of primary hypothyroidism and isosexual precocious pseudopuberty in females was first described in 1960 by Van Wyk and Grumbach. The unique elements that lead to the diagnosis are FSH-dominated sexual precocity with non advanced bone age in the presence of hypothyroidism.Objective and methods: Describe an 8.5 years old girl with hypothyroidism due to HT and clinical and hormonal features of Van-Wyk and Grumbach syndrome.<p...

Introduction: Childhood craniopharyngioma (cCP) has excellent survival, but quality of life may be severely hampered by hypothalamic dysfunction. We aimed to evaluate treatment and hypothalamic outcomes of a Dutch cCP cohort, and evaluate the effect of centralization of care.Methods: A retrospective cohort study was performed, including cCP patients diagnosed between 2004-2021. Treatment characteristics and hypothalamic ...

Background: Van Wyk Grumbach (VWG) and Kocher Debre Semelaigne (KDS) syndromes are rare syndromes with clinical manifestation of hypothyroidism associated with precious pseudo puberty and myopathic pseudomuscular hypertrophy. We present two cases that have the characteristic of both VWGS and KDSS syndromes developed in association with a long-term untreated hypothyroidism.Case 1: Seventeen years old girl was referred to our hospital due to menstrual irre...

Background: Ellis van Creveld syndrome (EVC) (chondroectodermal dysplasia) is a rare, multisystem disorder. It probably affects only around 1 in every 150,000 individuals. It is characterized by a long, narrow trunk and shortened arms and legs; extra fingers (postaxial polydactyly), and abnormalities of the oral region and teeth. In infants, non-bony manifestations, particularly congenital heart defects, may be health or life-threatening.Case presentatio...

Background: Gender dysphoria is characterised by an incongruency between the perceived gender identity and the biological sex. The cause of gender dysphoria is unclear and environmental as well as genetic factors may be important. It is well known that during sexual differentiation sex steroids control not only the differentiation of the internal and external genitalia but also the sexual differentiation of the brain. Structural as well as functional differences have been show...

Background: The syndrome consisting of primary hypothyroidism, precocious puberty, and massive ovarian cysts was termed Van Wyk and Grumbach syndrome (VWGS) in 1960. Chronic lymphocytic thyroiditis is the more common cause of hypothyroidism in children. In patients with severe longstanding hypothyroidism, the sella turcica may be enlarged due to thyrotrope hyperplasia. Puberty tends to be delayed in hypothyroid children in proportion to the retardation in the bone age, althoug...

Context: In children with Prader-Willi syndrome (PWS), the benefits of growth hormone (GH) treatment are well established. Currently, when young adults with PWS have attained adult height (AH), they have to stop GH treatment. Several one year studies have shown that GH treatment is also beneficial for adults with PWS, improving body composition. However, little is known about the longer-term effects.Objective: To investi...

Background: The majority of children diagnosed with idiopathic isolated growth hormone deficiency (IIGHD) show a normal growth hormone (GH) secretion (assessed by GH stimulation tests) when retested at near adult height (NAH). It appears plausible that if normal stimulated GH secretion is observed in mid-puberty, continuing recombinant human GH (rhGH) treatment may only have a minor effect on NAH. The effect on NAH has never been investigated in a prospective ...

Background: Prader–Willi syndrome (PWS) is characterized by a switch in early childhood from failure to thrive to excessive weight gain and hyperphagia with impaired satiety. The underlying mechanism for this switch may involve hyperghrelinemia, but only poor data exists regarding levels of acylated ghrelin (AG), unacylated ghrelin (UAG), and the AG/UAG ratio in PWS.Objective and hypotheses: To investigate plasma levels of AG and UAG in PWS, compare...
