Coated Pellets With Controlled Glucose Release in Treatment of Children with Diabetes

Neumann David , Franc Ales , Muselik Jan

Background: Usually a diet plan includes meals with suitable glycaemic index together with sophisticated insulin delivery for balanced sacharides-insulin intake. Nevertheless, the need of controlled sugar release is urged in specific day-to-day life situations, especially for young children with diabetes. Nocturnal hypoglycaemia, parental fear of insufficient snack intake in nursery, sports with prolonged race periods and others are amongst these life situations.<p class="...

Urinary Iodine Concentrations in Mothers and their Term Newborns

Krylova Katerina , Bilek Radovan , Bayer Milan , Dejmek Petr , Neumann David

Background: The development of fetal thyroid gland and its function in fetus and newborn are influenced by maternal iodine supplementation and maternal disorders of thyroid gland. Pregnant and lactating women are considered a risk group, although the Czech Republic ranks among countries with sufficient iodine supply. In case of maternal iodine deficiency, fetus is more susceptible to other factors influencing fetal thyroid gland development and function and also its neurologic...

Endocrine care for gender incongruent children and adolescents in The Czech Republic between 2011-2020

Neumann David , Snajderova Marta , Fifkova Hana , Weiss Petr , Zapletalova Jirina

Background: Gender incongruence (GI) is a topic of interest with major impacts on both the individual and society. In recent years, the small group of gender non-conforming children with an early GI history that persists through adolescence has been accompanied by a substantial rise in the proportion of adolescents reporting their gender doubts. The onset of gender dysphoria in this group is rapid. In the Czech Republic, multidisciplinary teams strive for high...

Patterns of Thyroglobulin Levels in Infants Referred With High TSH on Newborn Screening, Compared with Iodine-sufficient Healthy Controls

Kallali Wafa , Neumann David , Krylova Katerina , Jones Jeremy H. , Smith Karen , Shaikh Guftar , Donaldson Malcolm

Background: Thyroglobulin (Tg) is exclusively synthesised by thyroid tissue and a potentially useful aid to diagnosis in congenital hypothyroidism (CH). However, its role has yet to be fully evaluated.Objective: To examine the sensitivity and specificity of Tg in helping define the etiology of CH.Patients and methods: Tg was measured in a single laboratory by Immulite 2000 chemiluminescent immunometric assay (CVs 9.8, 5.7 and 5.7% ...

Does serum thyroglobulin predict thyroxine requirement during infancy in athyreosis and thyroid ectopia?

Kallali Wafa , Neumann David , Jones Jeremy , Hunter Ian , Tasker Anthony , Smith Karen , Shaikh Guftar , Donaldson Malcolm

Background: Thyroglobulin (Tg), a protein synthesized uniquely in the thyroid gland, may be elevated in primary congenital hypothyroidism (CH) due to increased TSH drive, absent in true athyreosis and Tg deficiency, and very elevated in some types of dyshormonogenesis.Hypothesis: Serum Tg at the time of newborn screening may reflect the amount of thyroid tissue present in apparent athyreosis and thyroid ectopia, and henc...

Severe Short Stature and GH Insensitivity Due to a De Novo Heterozygous STAT5B Missense Mutation

Klammt Jurgen , Neumann David , Andrew Shayne F , Drahosova Marcela , Stobbe Heike , Buckham Kyle , Rosenfeld Ron G , Pfaffle Roland , Hwa Vivian

Background: GH insensitivity is caused by disturbances of GH receptor function or inability to transduce the hormone signal. Affected children are severely growth retarded and may also present immune complications when the transducer STAT5B is defective. Only autosomal-recessive STAT5B mutations have been described to date.Clinical case: Two male 14.5 year monozygotic twins presented with heights of 131.5 cm (−5.3 SDS). Bone age of the ind...

Heterozygous Dominant Negative STAT5B Variants associated with Short Stature and GH Insensitivity

Pease-Gevers Evelien , Neumann David , Klammt Jurgen , Andrew Shayne , Kowalczyk Julia , Metherell Lou , Dattani Mehul , Hwa Vivian

Background: Homozygous mutations in STAT5B result in GH insensitivity and immune dysfunction. Heterozygous dominant negative mutations have not been described.Aims and objectives: To characterize genomic STAT5B DNA in two families exhibiting short stature.Methods: Sanger sequencing of STAT5B from genomic DNA. Mutant STAT5B constructs were expressed in HEK293 cells.Results: ...

Background: Following a phase of feeding difficulties and underweight in early life, children with Prader-Willi syndrome (PWS) develop hyperphagia and a tendency towards severe obesity. Growth hormone therapy (GH) has been approved in PWS to compensate their growth failure but may exert also additional effects on muscle component and body composition as well.Objectives: We aimed to test if an early initiation of GH thera...
