Background: Vitamin D is an essential hormone in the homeostasis of calcium. Its main source is sun exposure. Changes in lifestyle and migratory movements have favored the reappearance of vitamin deficiency in our country.Method: We present three cases of newborn with hypocalcemic seizures, secondary to maternal vitamin D deficiency. Mother’s origin was North Africa.Results: Case 1: 7 days old male brought for several episodes...

Background: The main cause of secondary adrenal insufficiency (SAI) in children is prolonged treatment with exogenous corticosteroids. plasma cortisol (PC) levels after administration of ACTH is the most used indicator of adrenal function in clinical practice. However, salivary cortisol (SC) levels is emerging as an alternative technique in the diagnosis of adrenal pathology, especially useful in the paediatric population because it is a simple noninvasive test.<p class="a...

Background: The 12q14.3q15 microdeletion syndrome is a rare entity of which only 16 new cases have been described to date. The syndrome consists of the association of severe pre- and postnatal growth retardation, proportional short stature, psychomotor retardation and osteopoikilosis. The phenotypic appearance of these patients poses a differential diagnosis with Silver-Russell syndrome, among other entities.Clinical description: A 10-month-old boy was r...

Background: Preterm newborns due to their immaturity, a higher incidence of mortality and increased susceptibility to iodine, are at risk of decreased thyroid function. Low levels of thyroid hormones during a critical period for the development of the central nervous system may negatively affect their psychomotor development. Screening for congenital hypothyroidism with capillary TSH is invalid for preterm babies and would require an specific thyroid function control.<p cl...

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...

Background: Mexico is globally ranked as one of the countries with the highest incidence of congenital hypothyroidism. There are few studies that have searched for germinal mutations of candidate genes, such as NKX2-1, in patients with congenital hypothyroidism.Objective and hypotheses: i) To search for NKX2-1 mutations in blood samples of patients with confirmatory diagnosis of congenital hypothyroidism (CH) due to thyroid dysgenesis (...

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: Triple CFTR modulator therapy has been shown to improve lung function and quality of life in patients with at least one F508del mutation in the CFTR gen. However, effects on glucose metabolism are not yet well defined. This paper aims to describe the effects of this treatment on glucose metabolism in CF patients.Methodology: Ambispective study.Inclusion criteria: pati...

Introduction: Diagnosis of growth hormone deficiency (GHD) and idiopathic short stature (ISS) is not straightforward. Nowadays growth hormone (GH) stimulation tests play a key role in the diagnosis but they are controversial due to the lack of normative data, poor reproducibility and poor disease concordance.The magnetic resonance imaging (MRI) is also a tool in the study of patients with short stature. Structural alterations of the hypo...
