Introduction: Mutations in the thyroid hormone (TH) transporter MCT8 result in MCT8 deficiency, which is characterized by severe intellectual and motor disability and high serum T3 concentrations inducing thyrotoxicity in peripheral tissues. At present, no effective treatment is available, although preclinical studies suggest that the T3 analog Triac is a promising candidate to i) normalize serum T3 levels and thus alleviate the thyrotoxicosis and ii) restore TH signaling in t...

Background: Percutaneous epiphysiodesis (PE) around the knee is the treatment of choice in the Netherlands to reduce predicted excessive final height. Studies until now are limited, had small numbers of patients and short follow-up periods.Objective and hypotheses: This nationwide Dutch long-term retrospective follow-up study aimed to assess final height (FH), complications and satisfaction after PE. Primary hypothesis was: ‘The PE around the knee i...

Introduction: The association of juvenile hypothyroidism, precocious puberty and ovarian enlargement is known as Van Wyk and Grumbach syndrome (VWGS). This diagnosis is considered on the basis of imaging findings and thyroid function analysis.Case report: Herein we report a case of 9 years old girl was referred to the endocrinology department with a suspicion of precocious puberty after having progressive breast enlargem...

Introduction: Van-Wyk Grumbach syndrome (VWGS) described in 1960 associate Primary hypothyroidism to early puberty, polycystic ovaries and pituitary adenoma with or without hyperprolactinemia. It is a very rare cause of precocious puberty, which the etiopathogenis is not yet very clear.Observation: We report the case of an 8 year old girl known for trisomy 21, she presented a Primary hypothyroidism treated initially with...

Congenital adrenal hyperplasia (CAH) is a group of rare congenital disorders of the adrenal cortex due to a defect in one of the enzymes involved in steroid synthesis leading to cortisol deficiency and overproduction of adrenal androgens. In the most severe forms CAH is a life threatening disease due to the risk of Addisonian and salt wasting crisis. In the last 50 years diagnostics and treatment improved significantly. Patients are treated with lifelong replacement of glucoco...

Background: Association of hypothyroidism, isosexual precocious puberty and macrogonadism was first described by Van Wyk Grumbach in 1960. Van Wyk Grumbach syndrome (VWGS) was reported predominantly in females, precocious puberty and clinical picture of hypothyroidism being the clinical hallmarks.Objective and hypotheses: Publishing additional data on clinical and hormonal spectrum of VWGS, providing for better understanding of its pathology and primary ...

Background: Growth hormone therapy can be indicated for children who are born small for gestation age (SGA) (either birth weight or birth height < -2 SDS) without catch-up growth (height < -2.5 SDS) at age 4 years. Growth hormone therapy is considered a safe treatment.Case presentation: A 12-year-old girl was referred to the pediatric endocrinologist for short stature. She was born small for gestational age (birth ...

Background/ Aim: Over the past 6 years, the IGF1/ IGFBP3 generation test (IGFGT) has been used in Belgium in a standardized form to identify children with severe primary IGF1 deficiency (SPIGFD). In this study, the discordance of the IGF1 and IGFBP3 responses during an IGFGT and the prevalence of SPIGFD were analyzed in a cohort of children with short stature (height SDS < - 2) and presenting with low (below lower reference limit) serum IGF1 level and norma...

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...

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 ...
