Background: In Androgen insensitivity syndrome (AIS) is a hereditary disease in which AR mutations in 46,XY patients present with partial (PAIS) or complete (CAIS) defects in virilisation.Objective and hypotheses: The aim was to analyze the effect of lack of androgen action in germ cell (GC) health and survival along postnatal development, previous to Sertoli cell (SC) pubertal maturation.Method: The histological features and quant...

Background: Congenital GH deficiency (GHD) can be isolated (IGHD) or combined with other pituitary hormone deficiencies (CPHD). The identification of mutations has clinical implications for the management of patients and genetic counseling1.Objective: To prospectively conduct a molecular-genetic analysis in genes associated with IGHD or CPHD.Method: Forty patients with IGHD (n=8) or CPHD (n=32) were stu...

Background: Carriers of germline DICER1 mutations are predisposed to a rare cancer syndrome, the DICER1 syndrome, associated with tumors such as pleuropulmonary blastoma (PPB), ovarian Sertoli-Leydig cell tumors (SLCT), multinodular goiter (MNG), cystic nephroma (CN), embryonal rhabdomyosarcoma (ERMS) or primitive neuroectodermic tumor. DICER1 is involved in the generation of microRNAs (miRNAs), short, double-stranded, non-coding RNAs that modulate gene expression at ...

Background: Primary IGF1 deficiency can result from molecular defects in genes encoding for the GHR, IGF1, STAT5b and ALS. Heterozygous, activating mutations in the STAT3 gene have been recently described in children with severe growth failure associated with a spectrum of early-onset autoimmune disease.Case presentation: We report the molecular diagnosis in two unrelated patients with severe growth failure and IGF1 deficiency: P1, a 3.6 year ol...

Background: Disproportional short stature (DSS) is the most frequent clinical presentation of skeletal dysplasias, which are a heterogeneous group of more than 450 disorders of bone. Skeletal survey is important to establish the diagnosis and to guide the genetic test, but has several limitations, especially in mild and atypical cases.Objective and hypotheses: To identify the genetic aetiology of DSS by exome sequencing.Method: Who...

Introduction: The majority of children with short stature are classified as ISS by the absence of findings that could elucidate the cause of their growth impairment. Several monogenic defects have already been identified in children with ISS, but the candidate gene approach is not feasible when there are no specific findings to guide a specific genetic test.Objective: To evaluate the diagnostic yield of a targeted gene p...

Introduction: Generally, patients with X-linked hypophosphatemic rickets (XLH) experience normal puberty. However, they can be affected by metabolic and environmental factors that may predispose them to central precocious puberty (CPP) and impair their predicted final height, similar to the general population.Case Report: A female patient was diagnosed with XLH at three and received regular treatment with calcitriol and ...

Background: Patients with disorders of sex development (DSD) require multidisciplinary team management for etiology identification and gender assignment. Identification of mullerian structures is an important part of the evaluation process. Ultrasonography remains the first-line imaging modality to delineate mullerian structures; while the importance of magnetic resonance imaging (MRI) is insufficiently studied.Objective and hypotheses: To evaluate the d...

Background: Abnormal uterine bleeding is a common complaint among adolescents, however, there are no evidence-based guidelines for their treatment, and there is a paucity of outcome data available.Objectives: To describe the characteristics of adolescents with menstrual abnormalities and to describe management protocol outcomes.Methods: This is a retrospective study, based on infor...

Context: Nutritional vitamin D deficiency is rare in the high income countries; its manifestations are usually associated with the combination of accompanying risk factors, as malnutrition, chronic illness, dark skin or restricted exposure to sunlight due to cultural practices.Objective: The aim of this case report is to increase the awareness to severe vitamin D deficiency as a result of extreme indoor isolation due to ...
