Background: Immunoglobulin superfamily, member 1 (IGSF1) was originally proposed to function as an inhibin co-receptor in pituitary gonadotroph cells. More recently, however, loss of function mutations in the human IGSF1 gene were linked to a novel syndrome of central hypothyroidism, testicular enlargement, and variable prolactin-deficiency. Igsf1-deficient mice are also centrally hypothyroid, with reduced pituitary thyrotropin-releasing hormone receptor (<em...

Background: The flash glucose monitoring system (FGMS) has been a great advance in quality of life for patients diagnosed with type 1 diabetes (T1D). However, it is a more expensive method.Objectives: To describe the characteristics of the pediatric population (<18 years) diagnosed with T1D using FGMS, during one year in our community. To assess the degree of satisfaction and possible inconveniences. To evaluate the ...

Objective: To evaluate the pancreatic reserve and metabolic control in our patient diagnosed of type 1 diabetes over the last 20 years.Method: Retrospective cohort study of all patients <15 years, diagnosed in our community between 01/01/1995 and 31/12/2014. Variables: gender, age at diabetes debut, age at study, c-peptide after stimulation with glucagon at debut and 1 month after, HbA1c at debut, 1 month, 1 year, 2 years, 5 and 10 years of debut. Co...

Background: 15% of patients with Williams syndrome develop hypercalcemia that is described as mild and transient. There are, however, reported cases with severe hypercalcemia that did not respond to traditional therapy. Pamidronate was used in the treatment of this condition, and was successful in the few reported cases in the literature.Case presentation: We report a 9 month old female who presented with failure to thrive, polyuria and polydipsia. She h...

Background: Despite the multiple endocrine, cardiovascular, and gastroenterologic problems of patients with Williams-Beuren Syndrome (WBS), Studies considering metabolism and bone quality in WBS are almost entirely absent from the literature.Objective and hypotheses: We evaluate bone mineral status and metabolism in a cohort of patients with WBS.Method: Thirty-one children (15 females, 16 male...

Background: Thyroid disorders (subclinical hypothyroidism and structural abnormalities) are common in Williams syndrome (WS) patients.Objective and hypotheses: Central hypothyroidism and GH deficiency (GHD) in a WS patient are discussed.Method: Case report and literature review.Results: A 5-month-old male was admitted to our hospital because of growth failure since the 3rd month, mild dysmorphisms, micropenis...

Background: A mutation in EIF2S3 (NM_001415; Xp22.11) was previously associated with microcephaly and developmental delay in a single pedigree. EIF2S3 encodes the eukaryotic translation initiation factor 2 subunit 3 (eIF2γ), the largest of three EIF2 subunits. EIF2 initiates protein synthesis by forming a ternary complex with GTP and initiator methionyl-tRNA which then binds to the 40S ribosomal subunit, enabling scanning of mRNA from the 5′ end to...

Background: WBS is a rare genetic disorder characterized by distinctive facial features, intellectual disability, cardiovascular anomalies, and infantile hypercalcemia.Objective and hypotheses: Majority of WBS cases occur sporadically, only five families with clinically confirmed WBS have been identified by molecular cytogenetic analysis. Here, we report on the three molecular cytogenetically confirmed familial WBS detected in a family with familial shor...

Introduction: IPEX syndrome is a syndrome characterized by the following triad: immune dysregulation, polyendocrinopathy and X-linked enteropathy. It is produced by a variant in the FOXP3 gene. It is a rare disease with poor prognosis.Clinical case: We are reporting the case of a boy, 2nd child of non-consanguineous parents, normal pregnancy. Born at 39 weeks of gestational age, birth weight 2985 grams and length 49 cent...

Background: DICER1 syndrome is caused by germline mutations in the DICER1 gene. It is associated with a wide spectrum of benign and malignant neoplasms, which are accompanied by specific somatic mutations in DICER1. Multinodular goiter (MNG) is a common clinical feature of DICER1 syndrome in children and adults; the thyroid ultrasound (US) features of MNG in the setting of DICER1 syndrome have not been widely reported.<...
