Background: Nutritional rickets (NR) is the most common growing bone disease, and vitamin D deficiency (VDD) may predispose to other diseases (diabetes mellitus, cancer, and multiple sclerosis). Maternal VDD and exclusive breastfeeding without supplementation are the most frecuent causes of NR in the neonate. VDD is still a problem in Europe. There are few reports of maternal hypovitaminosis D and rickets in bottle-fed infants during early infancy. We report a case of Nutritio...

Introduction: 46,XY gonadal dysgenesis (GD) represents a heterogeneous group of disorders/differences of sex development (DSD) characterized by abnormal gonadal development leading to a wide phenotypic spectrum. Variable degrees of external genitalia undervirilization are observed, ranging from micropenis to female-like genitalia and partially or fully-developed Mullerian derivatives.Case Report: A 6 years-old boy follow...

Background: Several lines of evidence suggest that the adult pituitary contains a population of tissue-specific stem cells capable of differentiating into hormone-producing cells. Previously, we have shown that Sox2+ve cells are able to self-renew and differentiate in vitro, suggesting that this population of undifferentiated cells may contain stem cells in vivo. When targeted with oncogenic mutations adult stem cells can become cancer stem cells, able to self-renew and give r...

Introduction: Diet plays a key role in the management of type 1 diabetes (T1D), thus nutritional education is a cornerstone in T1D therapy. The integration of nutrition knowledge into nutritional behavior may help parents inculcate a healthy lifestyle to their children. However, parents' diet and its potential impact on metabolic control of the disease of their children have been scarcely analyzed. This study was aimed to examine whether parents' foo...

Introduction: To achieve glycemic control goals in patients with type 1 diabetes (T1D), they are instructed in three fundamental principles: diet, insulin therapy and physical activity. Physical activity recommendations for children and adolescents with T1D are the same as for the general population. Following the physical activity recommendations helps mitigate the increased cardiovascular risk inherent to DM. We set out to explore the degree of glycemic cont...

Introduction: Short stature is frequently caused by SHOX variants causing functional deficiency. SHOX resides in the pseudoautosomal region (PAR1) of the sex chromosomes and SHOX/enhancer alterations result in a broad phenotypic range: from Langer mesomelic dysplasia, Léri-Weill dyschondrosteosis to idiopathic short stature (ISS). Growth hormone (GH) therapy is indicated for those individuals with short stature due to SHOXdeficiency. A frequent limitati...

Introduction: Bone fragility or predisposition to fractures with low-impact energy is a rare but potentially limiting condition. Variations in PLS3 gene are a cause of monogenic osteoporosis due to the alteration of osteoclast and osteocyte function and bone mineralization. It is characterized by early-onset osteoporosis, peripheral fractures, vertebral compression fractures and thoracic kyphosis. Due to its X-linked inheritance, the phenotype is more severe i...

Introduction: Short stature is a frequent reason for consultation in the paediatric age group. After appropriate clinical, radiological and laboratory evaluation, up to 60-80% of children are classified as idiopathic short stature (ISS) because no underlying cause can be found. Nowadays, the spreading of molecular is revealing that many of the patients initially classified as TBI, have variants in genes involved in the growth plate development. IHH gene is inv...

Plasmatic Calcium 9.3 mg/dl; phosphate 2.5 mg/dl; Alkaline phosphatasas 460 U/l; Parathyroid hormone 83 pg/ml; 25OH Vitamin D 24 ng/ml.

Premature adrenarche (PremA), is associated to increased adiposity and in girls to earlier puberty and adverse metabolic profiles. Recently, the use LC-MS/MS studies demonstrated adrenal production of more potent androgens:11-oxygenatedC19 steroids. Defining the mechanisms that regulate adrenal C19 steroid production has been elusive. We recently showed that genetic determinants of DHEAS during adrenarche differed from those identified during adulthood. One top variant was at ...
