Tumor induced osteomalacia, a rare and complex condition with more treatment options, exemplified in two patients.

Birkebaek Niels ,

Background: Tumor induced osteomalacia (TIO) is clinically characterized by bowed, short and painful legs in children and bone pain if onset in adolescent or adult life. Paraclinical, TIO is characterized by hypophosphatemia, low levels of 1.25-OH2-vitamin D (1.25 OH2D), and elevated levels of fibroblast growth factor 23 (FGF23). TIO is due to tumor secretion of FGF23, which inhibits phosphate re-absorption in the proximal renal tubules a...

Discrepancy in Bone Age Rating Using Tanner-Whitehouse Rating and Automated Bone Age Determination in a Child Who was Later Diagnosed with Metaphyseal Dysplasia

Birkebaek Niels , Hellfritzsch Michel

Background: In the last 50 years bone age has been manually evaluated using the method of Tanner and Whitehouse. Recently automated image analysis has been introduced for bone age determination. The automated method shows good agreement with manual evaluation; further, the precision of the automated method may be higher compared to the manual method.Objective and hypotheses: To report on the discrepancy of bone age determination using the manual TW2 meth...

Gene Dosage Changes in the GCK Gene not Detected by Sanger DNA Sequencing in Two Patients with Phenotypic MODY 2

Birkebaek Niels H. , Brusgaard Klaus

Background: Maturity onset diabetes of the young 2 (MODY2) is phenotypically characterized by elevated fasting and post-prandial blood glucose (BG) levels and no diabetes auto-antibodies. Inheritance is autosomal dominant, and it is caused by variants in the glucokinase (GCK) gene with resetting of the pancreatic glucose sensor to a higher level. It is essential to detect MODY 2 patients as they do not require treatment.Objective...

Hypothyroidism in a Child During Treatment with Nivolumab for a Glioblastoma

H Birkebaek Niels , Dahl Christine

Objective: The programmed cell death 1 protein (PD1) is a T lymphocyte membrane receptor, which when bound to its ligand PD – L1 inactivates the cytotoxic T lymphocyte, thereby down regulating the immune response. Cancer may upregulate PD – L1 on the cell surface, further downregulating the immune response. Nivolumab, a so called check point inhibitor, is a PD1 antibody, and when bound to PD1 keep the cytotoxic T lymphocyte active. Cytotoxic T lymphocyte activation b...

Two male siblings with extremely tall stature, moderate mental retardation and a deletion of ASH1L at chromosome 1q22.

Birkebæk Niels , Lildballe Dorte

Background: Several symmetric monogenic overgrowth syndromes with tall stature have been described, which is why children with syndromic tall stature should undergo comprehensive diagnostics. Tall stature has not been associated with chromosome 1.Objective: To present height growth and diagnostics in two male siblings with extreme tall stature and moderate mental retardation. Both had a deletion of ASH1L at chro...

Reproductive hormone levels in Minipuberty as a predictor of Testicular Endocrine Function and Penile Length in Healthy Young Men: An 18-year longitudinal Cohort Study

Henriksen Louise S. , Petersen Jorgen H. , Skakkebaek Niels E. , Jorgensen Niels , Virtanen Helena E. , Juul Anders , Toppari Jorma , Main Katharina M. ,

Background: Minipuberty denotes a period 1–6 months postnatally in boys during which a transient activation of the hypothalamic-pituitary-gonadal axis is observed. This early hormone activation can be used diagnostically in patients suspected of pituitary deficiency and differences in sex development. However, its significance for prediction of reproductive function in healthy young men is unknown.Objective: To eval...

S-25OHD is Associated with Hand Grip Strength and Myopathy at Five Years in Girls: An Odense Child Cohort Study

Al-Jwadi Rada Faris , Jespersen Eva , Dalgard Christine , Bilenberg Niels , Christesen Henrik Thybo

Context: Severe vitamin D deficiency may lead to myopathy in adults. Little is known about vitamin D and muscle strength in children.Objective: To test whether hand grip strength (HGS) in 5-year-old-children associates with serum 25-hydroxyvitamin D (s-25OHD) from pregnancy to 5 years.Methods: Observational study in the population-based Odense Child Cohort, Denmark. At 5 years, anthropometrics, body fat percentage by skin fold meas...

Adiponectin and Leptin in Children with Type 1 Diabetes for 3-5 years with or without Residual β cell Function

Birkebaek Niels H , Sorensen Jesper S , Kristensn Kurt , Pociot Flemming , Frystyk Jan

Background: Studies in adults with type 1 diabetes (T1D) have indicated that adiponectin is negatively associated and leptin positively associated with measures of a residual beta cell function (RBF).Objective and hypotheses: To compare serum adiponectin and leptin levels and their ratio in children with T1D for 3–5 years with and without RBF and in healthy children.Method: We included 342 children (173 females) with T1D, here...

Two Patients Presenting the Extremes of the Phenotypic Spectrum of 5 alfa Reductase Deficiency: One with at New Mutation

Jensen Karen S , Hvistendahl Gitte M , Kristensen Kurt , Olsen Henning , Vogel Ida , Birkebaek Niels H

Background: The large phenotypic spectrum of Disorders of Sex Development are caused by mutations in many different genes, but a large phenotypic spectrum of sexual disturbancies may also be seen with different mutations in the same gene.Objective and hypotheses: To report on one new mutation in the 5 alfa reductase (SRD5A2) gene, and describe the extremes of the phenotypic spectrum of 5 alfa reductase deficiency presented in two patients.<p class="a...
