Introduction: Despite existing guidelines there is no unified approach to glucocorticoid and mineralocorticoid replacement in congenital adrenal hyperplasia (CAH). Consequently, treatment varies in adults and children as well as across countries.Objective: We used data from the I-CAH Registry to identify geographical and temporal variations in the treatment with glucocorticoids and mineralocorticoids of children and adul...

An adolescent with Hypertension Caused by Primary Hyperaldosteronism due to KCNJ5 Mutation

van der Linde Annelieke , Deinum Jaap , Konijnenberg Yvette , Keijzer-Veen Mandy , Claahsen-van der Grinten Hedi

Background: Primary aldosteronism (PA) is a rare form of secondary hypertension. In adults PA is often caused by unilateral adrenal adenoma which can be cured by unilateral adrenalectomy. However, in young patients hereditary causes of PA have to be considered with bilaterally affected adrenal glands.Objective and hypotheses: We report on an adolescent with PA due to a recently described KCNJ5 mutation and want to point out the importance of performing m...

Impact of unilateral ovariectomy on ovarian function and pubertal development in girls with Turner syndrome

van der Coelen Sanne , Nadesapillai Sapthami , Peek Ronald , Braat Didi , Fleischer Kathrin , van der Velden Janielle

Background: A reduced reproductive lifespan is one of the most significant implications for girls with Turner syndrome (TS) and is due to an accelerated loss of ovarian insufficiency. Lately, there has been a surge in scientific research aimed at whether ovarian tissue cryopreservation (OTC) is a viable option for fertility preservation in girls with TS. This required a unilateral ovariectomy for girls with TS who may already have a poor ovarian reserve.<p...

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 ...

An Unusual Presentation of Hashimoto Thyroiditis (HT) and Precocious Puberty: The Van Wyk-Grumbach Syndrome

Leka-Emiri Sofia , Karachaliou Feneli , Fotinou Aspasia , Petrou Vassilis , Michalakos Stefanos

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...

Tall Stature and Macrodactyly of the Great Toes Due to a Novel Mutation in the Natriuretic Peptide Receptor-2 Gene

Lauffer Peter , van Duyvenvoorde Hemine , van Haeringen Arie , van der Kaay Danielle

Background: Mutations in the gene encoding the natriuretic peptide receptor-2 gene (NPR2) are responsible for monogenic growth disorders. Loss-of-function variants cause extreme short stature and skeletal dysplasia. Gain-of-function mutations cause tall stature with - in some cases - macrodactyly of the great toes, a Marfanoid habitus, arachnodactyly and scoliosis. We describe a novel gain-of-function mutation in exon 8 of NPR2 in a family wi...

Association of Van Wyk Grumbach and Debre Semelaigne Syndromes in Two Cases with Severe Hypothroidism

Demirel Fatma , Oden Alkim , Tayfun Meltem , Ucakturk Ahmet , Gungor Ali

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...

Linear Growth in a Child with Ellis Van Creveld Syndrome: Positive Effect of Growth Hormone Therapy

Soliman Ashraf , Alyafei Fawzia

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...

A 9-year-old girl with Van Wyk and Grumbach syndrome: precocious puberty as a rare consequence of hypothyroidism

Osokina Irina

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...
