Background: Recombinant human GH (rhGH) is normally administered as a daily s.c. injection. NNC0195-0092 is a reversible albumin-binding GH derivative developed with the aim of reducing clearance and thereby extending the exposure. It has previously been demonstrated that NNC0195-0092 is well tolerated in healthy subjects with the potential for once weekly administration.Objective and hypotheses: In this trial NNC0195-0092 was administrated subcutaneousl...

Background: Alterations in the timing or expression level of players involved in sex determination and differentiation can cause disorders of sex development, gonadal dysgenesis and germ cell neoplasms later in life. The mitosis–meiosis switch is one of the first manifestations of female sex differentiation and we hypothesise that a conflict between meiosis-inhibiting (male pathway) and meiosis-inducing signals (female pathway) is one of the possible mechanisms for disrup...

Background: X-linked hypophosphatemia (XLH) are rare, inheritable disorders caused by excessive renal phosphate wasting manifesting as rickets in children and osteomalacia in adults. While conventional medical treatment with oral phosphate and alfacalcidol is recommended in childhood, where it heals rickets and rescues some of the growth potential prior to fusion of the growth plates, it is controversial whether adults should continue therapy. There is little evidence for the ...

Introduction: Multiple endocrine neoplasia 2B (MEN2B) is a rare cancer syndrome primarily caused by the M918T (95%) and A883F (<5%) germline mutations in the REarranged during Transfection (RET) proto-oncogene. Aggressive and early onset thyroid medullary carcinoma is the hallmark of the disease. Cure rates in M918T carriers who had thyroidectomy before and after 1 year of age were 83% and 15% respectively. More t...

Background: Hypercalcaemia in infants may reach extreme levels due to hyperparathyroidism, subcutaneous fat necrosis, or vitamin D intoxication. Normal values for p-parathyroid hormone and p-calcitriol prompt search for other causes.Methods: Hospital file evaluation, case report.Results: A 5½-months-old Caucasian girl of non-consanguineous healthy parents was referred due to w...

Background: X-linked hypophosphatemia (XLH) are rare inheritable disorders caused by excessive renal phosphate wasting manifesting as rickets in children and osteomalacia in adults. Osteoid accumulates due to the reduced mineralization rate. Based on previous histomorphometric bone biopsy studies it the impression that XLH is a low bone turnover disease. Very little is known about the level of bone markers in XLH and the effects of conventional medical treatment with oral phos...

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...

Background: Childhood obesity and related co-morbidities are increasing world wide and consequently effective treatment interventions are much needed.Objective and hypotheses: The aim was to investigate concomitant changes in body composition in relation to changes in BMI–SDS during The Children’s Obesity Clinics Treatment (TCOCT) program. Hypothesis: reductions in body fat percentage may not be revealed by reductions in BMI–SDS.<p cla...

Background: Vitamin D deficiency in children clinically manifests as rickets causing growth impairment and bowing of the long bones, potentially increasing the ratio between crown-rump length and length (CRL:L) or sitting height and height (SH:H).Objective and hypotheses: We investigated whether CRL:L in 19-months-olds and SH:H in 36-months-olds were lower with higher cord 25hydroxyvitamin D (25OHD).Method: Participants were includ...

Background: Animal studies suggest a role of vitamin D in fetal lung development although not studied in preterm animals.Objective and hypotheses: We tested the hypothesis that vitamin D depletion does not aggravate respiratory insufficiency in preterm rat offspring. Furthermore, the effects of vitamin D depletion on growth and lung surfactant were investigated.Method: Female Sprague-Dawley rats were randomly assigned low vitamin D...
