Background: Patients with Klinefelter syndrome (SK) have a 47, XXY karyotype and tall stature as a result of overexpression of the SHOX gene. The case of a patient with peculiar phenotype, microcephaly, proportional short stature and 47, XXY karyotype with a deletion in band p11.3 of one X chromosome is presented.Clinical description: A 2-year, 4 month-old boy was referred for study of growth retardation. The product of a first gestation of 39 weeks of h...

Background: Gene SHOX haploinsufficiency due to deletions or mutations in heterozygosis causes a wide spectrum of phenotypes ranging from very severe disharmonic short stature (S. Léri-Weil, S. Turner) to very mild forms with the appearance of idiopathic short stature (IST) of difficult clinical recognition. Auxological study directed at evaluating body disproportions such as the sitting height/height (SH/H) ratio in patients with IST has been postulated as usefu...

Background: Hypochondroplasia is an osteochondrodysplasia inherited in an autosomal dominant pattern that results in a disproportionately short stature, characteristic facial features and skeletal alterations such as lordosis and genu valgum. Haploinsufficiency of the fibroblast growth factor receptor 3 gene (FGFR3) is responsible for 50–70% of the cases, but a negative result doesn’t rule it out.Case presentation: We report a...

Introduction: Continuous-glucose monitoring (CGM) is becoming a useful tool to evaluate glucose profiles in real-life conditions and to detect glucose abnormalities undetected by OGTT in CF patients.Objectives: • Evaluation of OGTT and CGM results longitudinally • Evaluation of BMI z-score and %FEV1 changes in relation to OGTT and CGM results. • Analysis of 6 proposed criteria to classify glucose abnormali...

Introduction: The identification of obese patients with increased susceptibility and risk for glucose intolerance and type 2 diabetes requires an oral glucose tolerance test (OGTT). Reference values for Body mass index (BMI) and Tri-Ponderal mass index (TMI) according to age and sex of healthy children in Spain without malnutrition or obesity have recently been published (*). TMI values remain very uniform in both boys and girls from the age of 8 to 18 years, ...

Introduction: Thyroid dyshormonogenesis is a heterogeneous group of hereditary diseases produced by the total/partial blockage of the biochemical processes involved in thyroid-hormone synthesis and secretion. Many genes are involved in this process. PAX8 is a transcription factor essential for thyroid-gland morphogenesis and synthesis of thyroid hormones, since it activates TG, TPO and TSHR gene transcription. More than 50 PAX8</...

Aggrecan is a structural glycoprotein of the extracellular matrix of cartilage present in the articular cartilage, growth plate and cartilage of the intervertebral disc. Biallelic pathogenic variants are the cause of aggrecan type spondyloepiphyseal dysplasia (OMIM#612813) while the presence of heterozygous pathogenic variants determine Kimberley type spondyloepiphyseal dysplasia (OMIM#608361) and short stature associated or not with acceleration of bone maturation and early o...

Objective: To describe efficacy and security of treatment protocol with gonadotropins in adolescents with hypogonadotropic hypogonadism (HH).Methods: Prospective study of patients with HH who received hGH and rhFSH in puberty. HH diagnosed during first months of life or in adolescence (testicular volume<4cc in >16 year-old with FSH<1.2UI/L, testosterone<40ng/dL and GnRH-test with LH-peak<6UI/L)<p class...

Introduction: it has been widely demonstrated that high physical activity (PA) levels prevent obesity development. The practice of moderate, regular PA reduces abdominal obesity, hypertension, insulin resistance, dyslipidemia and improves risk factors for obesity-related comorbidities (e.g. diabetes or cardiovascular diseases) independently of weight loss. However, in the childhood population, where sedentary behavior has increased in recent decades, few studi...

Introduction: Ovarian stimulation syndrome (OSS) in an infrequent disorder, in preterm infants under 30 weeks gestation. The are very few cases described in the literature. The immaturity, lack of gonadal axis feed-back or mutations in the FSH receptor genes, may explain its physiopathology. We present the case of a 26-week neonate with this syndrome.Case summary: 26-week newborn with extremely low weight (460g) born by emergency cesarean section due to ...
