Importance of Growth Factors and Bone Maturation Ratio in the Response to Growth Hormone Therapy.

Objective: The aim was to identify the influence of insulin-like growth factor I (IGF-1), IGF-binding protein-3 (IGFBP-3), and bone age (BA)/chronological age (CA) ratio on the response to GH therapy after 1 and 2 years of treatment and upon reaching final height.

[Allan-Herndon-Dudley syndrome: a diagnosis to rule out in any male infant with undiagnosed hypotonia].

Unlabelled: Allan-Herndon-Dudley syndrome is a rare X-linked genetic disorder, caused by a deficiency of the monocarboxylate transporter 8 (MCT8), a specific transporter of thyroid hormones, with functions mainly at the brain level. The syndrome produces an early onset of severe neurological disorder, in which hypotonia predominates.

Objective: To present a rare case with an unexpected diagnosis, highlighting the usefulness of requesting a complete thyroid profile in every hypotonic male infant without a specific cause.

Patients And Method: Observational, prospective, descriptive and analytical study of the neurocognitive assessment performed, with Brunet-Lézine test, on SGA children (n = 91) from 3 to 24 months of age, comparing with own controls.

Growth hormone deficit: Influence of puberty on the response to treatment.

Introduction: Short stature is the most frequent reason for consultation in Pediatric Endocrinology consultations and sometimes requires treatment with growth hormone. The aim of the study was to analyze the response to treatment based on its onset in pubertal or prepubertal stages and to analyze the possible benefit of an early onset.

Patients And Methods: Longitudinal, retrospective and observational study in 139 patients treated for idiopathic growth hormone deficiency up to adult height.

Growth hormone deficit. Does the first year of treatment influence adult height?

Introduction: Short stature is the most frequent reason for Pediatric Endocrinology consultations and sometimes requires treatment with growth hormone.

Objective: The possible correlation of a good response to any early response factor with a better final response was studied, and also whether there was a difference in response to treatment according to the type of deficit.

Patients And Methods: This was a longitudinal, retrospective and observational study of 139 patients treated for idiopathic growth hormone deficiency up to adult height.

Impact of adherence on growth response during the first 2 years of growth hormone treatment.

Purpose: Adherence to growth hormone (GH) treatment impacts clinical outcomes. The aim of this study is to assess the impact of adherence to rhGH treatment (2 years) on auxological outcomes.

Methods: Multicentric, retrospective observational study in rhGH-naïve GHD/SGA children treated with Saizen® during ≥2 years.

Osteogenesis imperfecta: Review of 40 patients.

Introduction: Osteogenesis imperfecta (OI) is a heterogeneous genetic disease manifesting as bone fragility and fractures.

Patients And Methods: Retrospective descriptive study analysing clinical and genetic features, and treatment of patients with OI.

Results: Forty patients were included; 32.

Adult height in short children born small for gestational age treated with growth hormone.

Background And Objective: Recombinant human growth hormone (rhGH) treatment in small for gestational age (SGA) children has been effective, although there is significant variability in the response. Adult height and the factors that determine the long-term response are evaluated.

Background: the main action of vitamin D is to maintain the concentration of calcium and phosphorus within the physiological range, allowing normal metabolism and bone mineralization. Vitamin D receptors have recently been described in many tissues, therefore vitamin D deficiency has been related not only to rickets, but also to increased risk of diabetes, obesity, cardiovascular, oncological, infectious and autoimmune diseases.

Objective: the aim of the study was to know the vitamin D concentration in a healthy pediatric population and to verify its influential factors, as well as to analyze the current situation of vitamin D prophylaxis and to evaluate the effectiveness of current recommendations.

Use of speckle tracking in the evaluation of late subclinical myocardial damage in survivors of childhood acute leukaemia.

Heart disease is the leading cause of non-cancer death in childhood cancer survivors. to determine the prevalence of subclinical cardiac dysfunction using speckle tracking and compare its results with those obtained by classical methods of assessing left ventricular function and its relationship with different factors to identify the population at higher risk. Echocardiographic assessment of left ventricular function included ejection fraction, tissue Doppler, longitudinal/circumferential strains and biochemical parameters (troponin-T and Pro-BNP) in a cohort of 57 survivors of childhood acute leukaemia with at least 10 years since diagnosis.
