Introduction: X-linked hypophosphatemia (XLH), due to PHEX mutation, is the most common genetic form of rickets in children. This rare disease is characterized by decreased tubular reabsorption and increased renal loss of phosphorus due to increased FGF-23 levels. In children, XLH is often manifested by short stature, rickets and bowel limbs deformity. Conventional treatment with oral phosphorus salts and calcitriol is not always well tolerated which has a pro...

Aim: to assess and follow-up anthropometric and biochemical parameters in patients with abdominal obesity after a lifestyle intervention.Patients, Material and Methods: 122 children and adolescents with abdominal obesity, aged 7 to 16 years, were included in a control randomized intervention study (NCT031472). Abdominal obesity was diagnosed using the waist circumference. The intervention included an intensive phase duri...

Introduction: Hypothyroidism is a frequent endocrinopathy in pediatric age. The most common manifestation in children is growth delay with decreased height velocity. Symptoms can be insidious and, if not identified ant treated, result in short stature.Aim: To evaluate stature catch-up after replacement therapy in children with primary acquired hypothyroidism.Methods: Retrospective study of all children with primary acquired hypothy...

Background: Life expectancy of children with human immunodeficiency virus (HIV) has increased due to highly active antiretroviral therapy. Metabolic disorders and changes in bone mineral density (BMD) are common in adult patients with HIV. There are few studies evaluating metabolic and bone involvement in children.Objective and hypotheses: To evaluate metabolic disorders and BMD in vertically HIV-infected children in four Chilean hospitals.<p class="...

Background: One of the limiting factors in adherence to GH therapy, is satisfaction with the administration device used.Objective and hypotheses: With the emergence of a new biosmiliar GH (BGH) administration device, we will assess the simplicity, ease of use, management and pain perceived by the patients.Method: Prospective through survey caregivers and children treated with BGH at least for 6 months. Signed informed consent was r...

Aim: to evaluate sleep quality by accelerometry and its association with anthropometry and biochemical parameters in children and adolescents after a multidisciplinary interventionSubjects Materials and Methods: One hundred and twenty-two children and adolescents with abdominal obesity, aged 7 to 16 years, were included in a multidisciplinary intervention study to lose weight. Abdominal obesity was diagnosed using the waist circumference...

Introduction: Noonan syndrome (NS) is one of a group of diseases known as rasopathies, which share a common molecular substrate: alterations in the RAS-MAPK signaling pathway. NS is characterized by clinical and genetic heterogeneity. Up to 50% of cases are caused by variants in the PTPN11 gene, although more than 10 genes have been identified as involved in the pathogenesis of this disease with marked clinical overlap.Objectives...

Introduction: Peripheral precocious puberty is a non-gonadotropin-dependent early pubertal development. Exogenous intake of sex steroids, gonadal or adrenal pathologies, ectopic hCG-secreting lesions play a role in the etiology. Adrenal tumors is a rare cause of heterosexual precocious puberty.Case: An eight-year-old female patient was admitted with the complaints of genital hair growth and breast enlargement. The patien...

Background: Thiamine-responsive megaloblastic anemia syndrome (TRMA) is characterized by a triad of megaloblastic anemia, progressive sensorineural hearing loss, and diabetes mellitus (DM). It is due to an inherited mutation in SLC19A2 gene, encoding a high-affinity thiamine transporter 1 in charge of facilitating the uptake of thiamine by the cells. Other manifestations including optic atrophy and stroke are rarely reported. We herein report an extremely rare...

Three patients from two unrelated families in Malta; one consanguineous (siblings: Patient 1, male and Patient 2, female) and one non-consanguineous (Patient 3, male), manifested hypogonadotropic hypogonadism with delayed puberty, intellectual disability, scoliosis, and ataxia with cerebellar hypoplasia on MRI. GnRH tests revealed low peak LH and FSH concentrations in the patients: Patient 1; LH 2.3 IU/L, FSH 4.4 IU/L (14.3y), Patient 2; LH 3.6 IU/L, FSH 6.4 IU/L (12.5y), Pati...
