Background: Congenital hypothyroidism (CH) is a common condition that occurs in ~1:3000–4000 live births and is one of the most common preventable cause of mental retardation with an early diagnosis and prompt pharmacological treatment. Neonatal screening has abolished this disease but 10% of children originally diagnosed with CH will have a transient form of the disorder and this percentage is increased during the last years due to a lowering of cut-off.<p class="abs...

Background: Short stature has been associated with a reduction in health-related quality of life (HRQoL) and more problem behavior in children and adults. In adolescents who were treated with growth hormone (GH) because of persistent short stature after being born SGA, an increase in HRQoL and decrease in behavioral problems was seen during or right after cessation of GH-treatment. However, long-term data, to analyze if these positive effects remain many years...

Introduction: Central Precocious Puberty (CPP) results from the premature activation of the hypothalamic-pituitary-gonadal axis. Is defined by the onset of secondary sexual characters before 8-years-old in girls and 9-years-old in boys. It’s associated with accelerated growth and advanced bone maturation and can lead to early epiphyseal fusion and reduced final height at adult age.Aims: To evaluate and compare the ...

Introduction: Since the 1980s, long-acting gonadotropin-releasing hormone analogues (GnRHa) have been the standard treatment for central precocious puberty (CPP).Aims: To evaluate the short-term response (at 6 and 12 months) of treatment with GnRHa in female children diagnosed with CPP, regarding growth, bone maturation (Greulich and Pyle method), predicted adult height (PAH) and pubertal development (Tanner stages)....

Background: Gonadal function is altered up to 25% in patients who suffered cancer in childhood. Cryopreservation of ovarian tissue (COT) is an option for preserving fertility.Aims and objective: To establish the prevalence of primary hypogonadism (PH) in children with cancer after hematopoietic cell transplantation (HCT). To analyse the variables that predict progression to PH.Methods: Retrospective cohort study. Patients aged 0 to...

Aim: Circulating levels of calprotectin have been reported in obesity-related chronic low-grade inflammation in adults, but has not been evaluated in pediatric population. We investigated serum calprotectin in overweight and obese children and its association with metabolic comorbidities.Methods: We enrolled 131 children (11.7±4.1 years). According to BMI, the subjects were divided into three groups: obese >95th percentile; overweight BMI 75th&#...

Background: The beginning and evolution of physiological puberty may be occurring earlier, resulting in change in the age at which clinical investigation on precocious puberty must be conducted, as well as concerns regarding the possible deleterious effects of hormone exposure in a later stage of life.Objective and hypotheses: Assess age of beginning and evolution of puberty in boys and girls acknowledging the age of thelarche (T), menarche (M), period b...

Background: Previous studies evaluating bone quality and microarchitecture in X-linked hypophosphatemic rickets (XLH) have produced conflicting data.Objective and hypotheses: To evaluate the bone mineral density (BMD) and microarchitecture in 36 XLH patients (13 children and 23 adults) with confirmed PHEX mutations compared to healthy controls.Method: The areal BMD (aBMD) at lumbar spine (L1-L4), femoral neck, total hip an...

Introduction: X-linked hypophosphatemic rickets (XLH) is characterized by a mineralization disorder in the growth plate and cortical and trabecular bones, resulting in bone deformities with anthropometric changes and potential alterations in body composition.Objective: To evaluate the body composition of 12 children and adolescents with XLH compared to healthy controls by anthropometric and densitometry data.<p class...

Growth hormone deficiency (GHD) is a relatively rare cause for short stature resulting from insufficient secretion of growth hormone (GH). With complicated etiology, GHD can coexist in numerous syndromes or disorders such as Turner Syndrome. So, it is necessary to take genetic analysis to patients with GHD especially those perform various phenotypes. A 9.5 years old boy complained of short stature was diagnosed with GHD by height velocity (HV) <5 cm/year, delayed bone age ...
