Introduction: Among children with short stature, some show persistent IGF-I levels <-2.0 SDS despite a normal growth hormone (GH) response in a stimulation test. This may be caused by conditions that could benefit from recombinant human GH (rhGH) therapy (e.g. GH neurosecretory dysfunction, bioinactive GH, partial GH insensitivity). Therefore, the IGF-I generation test (IGFIGT) was implemented in 2006 using a national, standardized protocol. Children with a...

Micropenis is defined as a penile length less than 2.5 SD below the mean value for a given age (eg, <2.5 cm at term). Nowadays, it should be also diagnosed in utero by sonography. The incidence of micropenis has been reported as 1.5/10.000 male infants in Usa, 5/1.442 in France and 18/2710 in Brazil, suggesting geographical differences or different assessment. Micropenis represents a clinical sign, that may be part of various clinical conditions, such as hypogonad...

Background: cryptorchidism is associated with the high risk of infertility. In some cases it may be the one of the first symptom of congenital hypogonadism. The period of 0 – 6 month of life is a short window for postnatal testicular maturation and the diagnostic of reproductive disorders.Objective: to evaluate the functional condition of pituitary and gonads in mini-puberty boys with bilateral cryptorchidism.<p...

Background: The period of transitory postnatal activation of the hypothalamo-pitutary-gonadal axis (mini-puberty) plays an important role in the testicular maturation.Objective and hypotheses: To evaluate the functional condition of the gonads in 1–3 months boys with cryptorchidism.Method: 40 boys ages 1–3 months with cryptorchidism were examined: group 1–30 boys with unilateral inguinal retention testis and group 2&...

Background: The influence of GH on prepubertal children with Kabuki Syndrome (KS) is a novel field of research. KS is a congenital anomaly/intellectual disability syndrome caused by a mutation in the KMT2D or KDM6A gene. These mutation causes distinct phenotypically features, such as short stature and facial dysmorphology. Earlier studies describe a high incidence of obesity in children with KS.Aims and objectives: In this prospective s...

Background: The influence of growth hormone (GH) on the metabolism of prepubertal children with Kabuki syndrome (KS) was never investigated before. Kabuki syndrome (KS) is a rare syndrome, which is mainly characterized by mental retardation, short stature, specific facial features, obesity and hypotonia. This syndrome caused by a mutation in the KMT2D or KDM6A gene.Objective and hypotheses: In this prospective study we investigated the ...

Background: Kabuki syndrome (KS; OMIM 147920) is a congenital anomaly/intellectual disability syndrome caused by a mutation in the KMT2D or KDM6A gene. Children with KS have a spectrum of clinical features, but one of the key features in KS patients is postnatal growth retardation. GH deficiency has been reported in some children with KS, but no structural research is done in this field.Objective and hypotheses: We studied the growth ho...

Background: Asymmetric dimethylarginine (ADMA) is an endogenous competitive inhibitor of endothelial nitric oxide synthase (NOS), which prevents synthesis of nitric oxide (NO). Low levels of NO are associated with endothelial dysfunction and an increased risk of cardiovascular disease. Diseases associated with high levels of ADMA include metabolic syndrome, chronic kidney disease, diabetes mellitus, insulin resistance, hyperthyroidism and multiple organ failure. Notable, GH tr...

Background: SIDM is not a common complication of high-dose glucocorticoid therapy (HD-GC) in pediatric practice. There are no clear generally accepted approaches to SIDM treatment. In 10 cases, we present the identified patterns of predictors, course, features of the treatment of SIDM in children and adolescents.Methods: 10 case histories of children with SIDM were analyzed. 4 boys, 6 girls, age 8-17.5 years, median 15 y...

Background: Human HSD11B2 metabolizes active cortisol into cortisone and protects the mineralocorticoid receptor from glucocorticoid occupancy. Loss of function mutations in HSD11B2 gene cause a rare autosomal recessive disorder, apparent mineralocorticoid excess, resulting in low-renin hypertension and hypokalemia.Objective: We present 2 children with apparent mineralocorticoid excess. Case 1, a boy presenting at 11 yea...
