Noonan syndrome patients with short stature at a single pediatric endocrinology centre

Deyanova Y. , Iotova V. , Tsochev K. , Stoyanova M. , Stoicheva R. , Mladenov V. , Bazdarska Y. , Galcheva S. , Zenker M. ,

Introduction: Noonan syndrome (NS) is caused by mutations in RAS/MAPK signaling pathway genes. About 70% of the NS patients have short stature, and human recombinant growth hormone (rhGH) is an established yet not fully standardized treatment.Objective: To assess the first 2 years rhGH treatment effectiveness in NS patients at a single centre.Materials and methods: A total of 20 (16 male) NS patien...

Two Siblings with Short Stature

V Sri Nagesh , Dauber Andrew , Kanithi Ravishankar , Dutta Deep , G Ram Kumar

2 siblings were referred for evaluation fo short stature and failure to thrive. Both were born of 3rd degree consanguinity, first and second in birth order. the first sibling was 2 1/2 year old at time of referral and had birthweight of 3.1 kg and had gross motor delay. Present height was 65 cm (SDS −6.2 S.D.)and weight was 6 kg (<3rd centile) Second sibling was 1.5 years old, with gross motor delay with height of 57 cm (SDS −6.5 S.D.</sma...

Adipocytokines Delay Pubertal Maturation of Human Sertoli Cells

Wagner Isabel V. , Yango Pamela , Svechnikov Konstantin , Tran Nan D. , Soder Olle

Background: Obesity and metabolic syndrome related co-morbidities are increasingly recognized in children. Reproduction is an important target of obesity complications, including adverse effects on spermatogenesis and steroidogenesis in males. Adipocytokines are key players in various complications of obesity.Objective and hypotheses: The aim was to study the potential effects of adipocytokines on Sertoli cell function and possibly link the findings to t...

Adipose Tissue – A Source of Hyperandrogenism in Obese Females?

Wagner Isabel V. , Sahlin Lena , Savchuk Iuliia , Svechnikov Konstantin , Soder Olle

Background: Obesity in females is often associated with metabolic complications and hyperandrogenism. However, the source of androgens is not entirely clear.Objectives and hypotheses: Our objective was to find out if adipose tissue (AT) is a site of steroid production during childhood and adolescence, and if this source could add to hyperandrogenism in obese females.Methods: Parametrial and inguinal adipose tissue was collected and...

Bone Geometry, Volumetric Density, Microarchitecture and Estimated Bone Strength Assessed by HR-pQCT in Adult Patients with Hypophosphatemic Rickets

Shanbhogue Vikram v. , Hansen Stinus , Folkestad Lars , Brixen Kim , Beck-Nielsen Signe Sparre

Background: Hypophosphatemic rickets (HR) are rare, inheritable disorders caused by excessive renal phosphate wasting. Despite a generalized mineralization defect, patients with HR are reported with a lower risk of fracture.Objective and hypotheses: The aim of this study was to evaluate the effect of bone -geometry, -microarchitecture and volumetric BMD (vBMD) on the estimated bone strength in adult patients with HR using high-resolution peripheral quant...

Epidemiology of Turner Syndrome in Iceland 1968–2012

Sigmarsdottir Arndis Audur , Johannsson Johann Heidar , Sigurjonsdottir Helga Agusta , Thorsson Arni V

Introduction: Turner syndrome (TS) is a common genetic disorders with an estimated range of occuring in 25–210 per 100 000 liveborn females. In Denmark the prevalence of TS has been found to be 40 per 100 000 liveborn females. Our aim was to study the epidemiology of TS in Iceland for the period of 1968–2012.Methods: Primary source of data were hospital records and records from all pediatric endocrinologists in Iceland. To validate the data the...

Factitious Administration of Analogue Insulin to a 2-Years-Old Child

Thanawala Nehal , Cheney Sarah , Wark Gwen , Thevis Mario , Thomas A , Tziaferi V , Greening James

Background: Hypoglycaemia precipitated by factitious insulin administration presents in a very similar way to hypoglycaemia caused by hyperinsulinism. It is difficult to ascertain clinically if the hypoglycaemia is secondary to exogenous administration or endogenous insulin secretion. Diagnosis is based on circumstantial evidence and biochemical tests which include insulin and C-peptide level.Objective and hypotheses: We would like to report a case of a ...

Childhood Obesity Negatively Influences Adult Leydig Cell Function

Wagner Isabel V , Kloting Nora , Kiess Wieland , Soder Olle , Svechnikov Konstantin

Background: Childhood obesity is a global health problem and co-morbidities develop already during childhood and adolescence. Male obesity impacts negatively on reproductive function. Testosterone is decreased, sperm quality reduced, and the physical and molecular structure of germ cells altered in obese males. However, less is known about the role of prepubertal obesity on future reproductive function. We therefore explored Leydig cell function and reproductive potential in a...

Background: 14½ year old girl presented with increased skin pigmentation, weakness of limbs and walking difficulty and delayed puberty.Objective and hypotheses: To evaluate the girl for the aetiology of hyperpigmentation, neuromuscular weakness and delayed development of secondary sexual characters.Method: The girl was evaluated by neurologist and found to have development delay, sensory and motor neuropathy, ataxia, amyotroph...

Hyperparathyroidism after three years of burosumab in children affected with x-linked hypophosphatemia

V Zhukouskaya Volha , Ertl Diana-Alexandra , Berkenou Jugurtha , Audrain Christelle , Bardet Claire , Rothenbuhler Anya , Linglart Agnes

Background/aim: Hyperparathyroidism (HPHT) is a common feature in patients with X-linked hypophosphatemia (XLH) especially when treated with vitamin D analogues and phosphate supplements. Although the exact mechanism is not clear, it is assumed that phosphate supplements taken chronically stimulate parathyroid hormone (PTH) secretion. We prospectively assessed the effect of a novel pathogenetic treatment anti-FGF23 (burosumab) on PTH levels in children with XL...
