van Roessel I.M.A.A. , de Graaf J.P. , Biermasz N.R. , Charmandari E. , van Santen H.M.

Objective: Hypothalamic dysfunction is a rare condition and can be encountered in patients who have been diagnosed or treated for a suprasellar brain tumor. Due to its rarity, signs and symptoms of hypothalamic dysfunction may be difficult to recognize, leading to delayed diagnosis of the suprasellar brain tumor or to difficulties in finding the health care expertise for hypothalamic dysfunction after tumor treatment. To improve care and outcome of patients wi...

Sobu Elif , Demirkol Yasemin Kendir , Yılmaz Gulay Can , Ozcora Gul Demet , Yenigurbuz Fatma

Introduction: Ellis Van Creveld syndrome (EVC) is a rare condition which is characterized with disproportionate short stature, postaxial polydactyly, and dysplastic nails and teeth. It is a rare autosomal recessive disorder due to mutations of EVC 1 and 2 genes located on chromosome 4p16. EVC syndrome is a chondroectodermal dysplasia. Congenital heart defects; especially atrial septal defect and single atrium occurs in 60% of affected individuals. Here we report a 5 year-old f...

An Unusual form of Precocious Puberty: Van Wyk and Grumbach Syndrome

Anık Ahmet , Avcı Esma Cigdem , Unuvar Tolga

Introduction: The association of precocious puberty and/or polycystic ovaries, delayed bone age and hypothyroidism is known as the Van Wyk and Grumbach syndrome (VWGS). Clinically this syndrome is a diagnostic challenge because hypothyroidism usually leads to pubertal and growth delay, whereas in case of VWGS hypothyroidism it leads to growth delay and precocious puberty. We report a boy with long-standing, untreated hypothyroidism who presented with precocious puberty.<p ...

The importance of thyroid function tests in precocious menarche: Van Wyk Grumbach syndrome

Köprülü Özge , Acar Sezer

Introduction: Van Wyk Grumbach Syndrome (VWGS) is characterized by untreated severe hypothyroidism, isosexual precocious puberty, multiple ovarian cysts and delayed bone age. The disorder is most likely due to complex interactions of the hormonal axis; (1) excess TSH stimulates the FSH-receptor, (2) pituitary enlargement and hyperstimulation, (3) secondary ovarian hyperstimulation. Although it is extremely rare, it is important to recognize before the unnecess...

Dikaiakou Eirini , Vlachopapadopoulou Elpis Athina , Kosteria Ioanna , Panos Alexandros , Dede Eirini , Koutrouveli Eleni , Zouridaki Christina , Michalacos Stefanos

Background: Van Wyk-Grumbach syndrome (VWGS) is a rare diagnosis that should be suspected in children with signs of peripheral precocious puberty and hypothyroidism. It is characterized by multicystic enlarged ovaries, in the presence of long-term severe hypothyroidism. Treatment of VWGS consists of hormonal replacement with levothyroxine. Usually, ovarian cysts and increased ovarian volume subside within an average of 2 months but can persist up to 12 months after treatment.<...

Introduction: Children with cancer are at increased risk of endocrine complications, especially children with a brain tumor. One of these late effects includes bone disorders (ranging from low bone mineral density (BMD) to osteoporosis). Children with a suprasellar Low Grade Glioma (LGG) may be especially at risk for bone problems due to exposure to multiple treatment modalities, hypothalamic dysfunction and/or decreased mobility in combination with vision los...
