Background: Dietary patterns have notably changed in Mediterranean countries during the last decades. Mediterranean diet (MeDiet) is associated with lower prevalence of cardiometabolic diseases.Objective and hypotheses: To assess adherence to MeDiet in children and adolescents with abdominal obesity during a comprehensive weight loss intervention.Method: Children and adolescents with abdominal obesity (waist circumference >p90)...

A female patient was firstly evaluated at the age of 12 years, complaining of headaches and visual loss. Physical examination demonstrated adequate height and weight, Tanner stage P1B1. Papillary edema was confirmed by fundus examination. MRI showed a pituitary macroadenoma, 6.6×7.3×6.1 cm with compression of the optic chiasm and bilateral cavernous sinus invasion. The first prolactin value obtained was 169.164 uUI/ml (normal<210) with the other pituitary axis wi...

Iodide (I−) transport defect (ITD) is an autosomal recessive disorder caused by the inability of the thyroid follicular cell to actively accumulate iodide. Active I− accumulation is mediated by the Na+/I− symporter (NIS), an integral plasma membrane glycoprotein located on the basolateral surface of thyrocytes. The diagnostic criteria for ITD include a variable degree of hypothyroidism and goiter, low to absent thyr...

Introduction: Complete ALS deficiency (ALS-D), caused by inactivating mutations in both IGFALS gene alleles, presents severe IGF1 and IGFBP3 deficiencies associated to moderate growth retardation.Aim: To characterize the molecular defect in a family where the index case and his father presented short stature and IGF1 and IGFBP3 deficiencies.Methods: IGF1, IGFBP3, and GH serum levels were determined by CLIA, ALS by ELISA an...

Background: Turner syndrome is the most common sex chromosome disorder in females and occurs in about 1/2500 newborn girls worldwide. On chromosomal analysis, the various karyotypes observed are: 45,X (50%); 45,X/46,XX (20%); 46,X, i(Xq) (15%); 46,X, r(X) or 46,X, del(X) (10%); and others (5%).Objective and hypotheses: We present the case of a 17-year-old girl referred to our service for primary amenorrhea. Clinical examination: height=163 cm (62nd perce...

Background: Ovotesticular DSD is a rare disorder defined by the presence of both ovarian and testicular tissues in the same individual. SRY is present in approximately 1/3 of patients with 46, XX ovotesticular DSD. In SRY-negative ovotesticular DSD, the mechanism responsible for the presence of testicular tissue is not yet understood.Case presentation: A male patient was referred to us for hypospadias and bilateral cryptorchidism at 2.5...

Introduction: Type 1 diabetes mellitus (T1DM) is associated with significantly higher cardiovascular disease mortality compared to the general population, even when glycated hemoglobin (HbA1c) is less than 7.0%. Inadequate body composition may increase the risk.Aim and Methods: To evaluate body composition of a group of pediatric patients with T1DM, from Portuguese Pediatric Endocrinology/Diabetic Clinic, using the bioim...

Indels are highly abundant in human genomes and have contributed massively to genome evolution. However, the role of indels and their underlined mechanisms of mutagenesis in Mendelian disorders still needs to be appreciated. To explore the contribution of indels in a monogenic disorder, we analyzed all indels already described in the AR gene, including three novel indels found in our cohort. We analyzed the indel distribution through the AR coding region, compared wit...

Introduction and Aims: Autosomal dominant hypocalcemia or type V Bartter syndrome is characterized by hypocalcemia, low parathyroid hormone (PTH), and calciuria, which marks its prognosis due to the risk of nephrocalcinosis. It is caused by activating mutations in the calcium-sensing receptor (CASR) gene (3q21.1), which is expressed in the parathyroid and renal tubules, causing salt and potassium loss, due to the inhibition of the ROMK and NKCC2 channels. We s...

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...
