X-linked hypophosphataemia (XLH) is a dominant disorder caused by mutations in PHEX (located at Xp22.1), associated with rickets, lower limb deformities, pain, poor mineralization of the teeth and disproportionate short stature in children. The characteristics and severity of XLH vary between patients. Early diagnosis and specific treatment is usually decisive to improve short and long term patient outcomes. We describe the variability of phenotype in two sisters carrying the ...

Uncontrolled diabetes mellitus is a disease with a wide range of systemic complications. Eye complications may seriously threaten quality of life. Diabetic retinopathy is the most frequent diabetic ocular complication. However, diabetic capilaropathy is a little known condition of diabetic retinopathy. It is an acute optic disc edema and/or macular edema; due to an acute hyperglycaemia.Method: We present a case of a diabetic 14-years-old female with diab...

Background: Congenital hypothyroidism (CH) comprises a heterogeneous group of disorders that includes diseases of the hypothalamo-hypophyseal system. The latter are missed on TSH based screening programs leading to increased morbidity and mortality. Additional T4 determinations, allows an early detection of CH of central origin (CH-C).Objective and hypotheses: To report the findings of a neonatal screening program based on determination of TSH...

Background: At present, literature regarding postnatal growth in small for gestational age (SGA) subjects and its’ correlation with growth factor levels is still controversial. A relation between IGF1 and IGFBP3 levels at birth and weight and length catch up growth has been demonstrated. In the first months of life a rapid weight catch-up growth has also been associated to an increase of leptin, basal insulin and insulin resistance.Objective and hyp...

Background: Peutz-Jeghers syndrome (PJS) is a rare autosomal-dominant disorder frequently caused by the serine-threonine-kinase-11(STK11) gene mutation and characterized by hamartomatous polyps throughout the gastrointestinal tract, mucocutaneous hyperpigmentation and predisposition to several malignancies. Rarely, PJS may be associated to an oestrogen producing large cell calcifying Sertoli cell tumour that may result in gynecomastia and increased growth velocity (GV).<p ...

Background: BoneXpert is a software for automated measurement of bone age (BA) and radiogrammetry (bone health index). The precision error of the software for BA measure is smaller than the human rating error and the accuracy relative to the human routine ratings is 0.80 years. Differences in skeletal maturation between ethnicities have been reported, so it is important to have specific references for the own population.Objective: To present the automate...

Introduction: Obesity is the main public health problem in Mexico. Several factors have been described as explanations, mainly: increased sedentarism and caloric intake. Such environment has been described as “obesogenic”. The aim of this study was to describe the relationship between the components of such obesogenic environment and the adiposity of Mexican children and adolescents.Methods: We carried a population-based cross-sectional study o...

Introduction: Growth prediction algorithms (i.e. iGRO), provide an estimate of a patients’ likely growth in the first year, and subsequent years, of GH treatment at a given dose, taking into account the patient’s combination of physical characteristics. Comparing a patient’s actual growth with their predicted growth after the first year of GH treatment, it is possible to determine whether the patient is responding to GH as expected (Index of responsiveness; IoR)...

Background: 2015 ATA Guidelines for management of medullary thyroid cancer (MTC) include C634 RET codon mutation in ‘High risk’ group, recomendating prophylactic thryroidectomy before 5 years old based on serum basal calcitonin levels (SBCt).Objective and hypotheses: We present 14 pediatric patients with C634 RET codon mutation, who underwent prophylactic thyroidectomy in our center, their clinical and analytical features and anatomopathologica...

Background: Pediatric Central Nervous System (CNS) neoplasms are the most frequent solid tumors in children. Since the increase in survival, the patients are in high risk of developing long term sequelae. Endocrinological sequelae may be due to the oncological disease itself but usually derived from the treatment received, and they affect 20–50% of patients long-term. We aimed to review our experience from 2005 to 2015.Objective and hypotheses: Desc...
