Background: Patients affected by pseudohypoparathyroidism type 1b (PHPI-b) develop resistance to PTH leading to hypocalcemia and hyperphosphoremia, which is often associated with resistance to TSH. PHP-Ib is associated with methylation changes at one or several differentially methylated regions (DMRs) within the GNAS complex locus, located at 20q13.2–13.3. This locus gives rise to several different transcripts (NESP55, XL, A/B), with varying patterns of imprinted expressi...

Background: Multiple daily injections of insulin for children and young people with diabetes can be very daunting and, some have a phobia of needles. As a result, for some individuals, the use of an i-port device can be life-changing and help with their diabetes management. The i-port is an injection port that enables diabetes patients to administer their insulin without having to puncture their skin multiple times in a day. In most cases, the i-port can stay ...

Tricho-rhino-phalangeal syndrome Type I (TRPS I) is a rare autosomal dominant genetic disorder clinically characterized by craniofacial and skeletal abnormalities, associated with cone-shaped epiphyses, brachydactyly and short stature. Although patients with TRPS I present various degrees of short stature, there are only four reports of growth hormone deficiency in patients with TRPS I. We present the case of TRPS I and partial GH deficiency. A 15-year-old female was referred ...

Background: Recently we described a family with several members having intrauterine and postnatal growth failure as well as signs of Silver–Russell syndrome (SRS) who carried a heterozygote nonsense mutation of IGF2. The patients had low IGF-II serum levels, but normal IGF-I serum levels.Objective and hypotheses: We aimed to estimate the diagnostic value of the IGF-II, IGF-I and IGFBP-3 measurements in the assessment of children with SRS.<p clas...

Background: In recent years more and more genetic defects along the GHRH–GH–IGF-I axis have been reported. Those mutations of the IGF-I receptor (R) are a rare abnormality of whom only the heterozygotes progenies survive.Objective and hypotheses: To determine the birth length, weight and brain size using head circumference and find out whether these correlate with the type of mutation.Method: Collection of data of 65 neon...

Background: Following the 2010 CAH consensus, the need for genetic confirmation of diagnosis remains uncertain and variation in practice is unclear.Methods: This variation was assessed by using the International CAH(I-CAH) Registry which was developed using the same platform as the I-DSD Registry.Results: After the development of the I-CAH Registry in October 2014, the rate of addition of CAH cases increased from 2/month to 14/mont...

Background: Arnold-Chiari malformations (CM), types I-IV, refer to a spectrum of congenital hindbrain maldevelopments characterized by downward herniation of the cerebellar tonsils. CM-I is defined as tonsillar herniation of 3–5 mm below the foramen magnum and is the most common and the least severe of the spectrum.Objective and hypotheses: Children with CM-I usually are asymptomatic and often diagnosed in adulthood, therefore early presentation of ...

Background: Children born small for gestational age (SGA) exhibit wide variations in the activity of growth hormone (GH)/insulin–like growth factor–I (IGF-I) axis and this heterogeneity may result in supra physiological concentrations of IGF-I during GH treatment. The long-term effects of elevated IGF-I levels has been a matter of concern. We explored the variations in total IGF-I and bioactive IGF-I and the associations with growth and glucose metab...

Growth hormone (GH) stimulates insulin like growth factor I (IGF I) release. IGF-I is the standard biomarker for monitoring GH effects during treatment and to achieve optimal long-term safety, and to a limited extent, monitor efficacy in children with GH deficiency (GHD). The IGF I profile during treatment with a long acting GH (LAGH), such as once weekly somapacitan (Novo Nordisk), differs from the daily GH profile by exhibiting larger peaks and troughs over the dosing interv...

Objective and hypotheses: The work was initiated to assess functional condition of the kidneys and to study interrelation between ACE gene I/D polymorphism and stage of chronic kidney disease in children and adolescents with type 1 diabetes mellitus (DM) in compliance with K/DOQI recommendations (2002).Method: We examined 120 children and adolescents with type 1 DM, 53 (44.2%) males and 67 (55.8%) females among them (mean age 13.8±0.24 years. GFR wa...
