Background: Recent studies have found a widespread deficiency of vitamin D during pregnancy. Its significance is still not fully understood, although low Vit-D levels have been associated to increased risk for conditions such as preeclampsia, bacterial vaginosis, neonatal sepsis, and early respiratory infections in the child. Supplementation to the pregnant mother is still a matter of debate, therefore it is important to understand better the causes, risk factors, and possible...

Introduction: Use of continuous glucose monitoring (CGM) as a diagnostic tool for cystic fibrosis-related diabetes (CFRD) is receiving increasing attention. We aimed to: i) describe the glucose profile by CGM in CF patients >10 years of age; ii) compare CGM and oral glucose tolerance test (OGTT) results; and iii) evaluate lung function and nutritional status changes over the previous year.Methods: Prospective study of CF patients aged ≥10 years...

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: 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: 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...

Introduction: The metabolically healthy obese phenotype (MHOF) defines obese patients who have preserved insulin sensitivity and who do not have metabolic complications: lower risk of cardiovascular disease and type 2 diabetes in adulthood. Recent studies indicate that TMI (kg/m3) estimates the percentage of body fat more accurately than the BMI and it has been proposed to substitute the use of the BMI z-score values by those of the TMI. TMI values ...

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, ...
