Aguilar-Riera Cristina , González-Llorens Núria , Mogas Eduard , Campos Ariadna , Fàbregas Anna , Fernández Paula , Vázquez Elida , Yeste Diego , Clemente María

Introduction: Congenital hypopituitarism is a heterogeneous disorder with isolated hormone deficiency(IPHD) or combined(CPHD). Main risk factors for CPHD include H-P abnormalities such agenesis corpus callosum(ACC), anterior pituitary hypoplasia(APH), ectopic posterior pituitary(EPP), pituitary stalk interruption(PSI), septo-optic dysplasia(SOD), and holoprosencephaly(HPE).Patients and Methods: Prospective and longitudin...

Massive adrenocortical carcinoma with right atrium invasion in a two-year old girl with li fraumeni syndrome – possibility of succesful ressection after neoadjuvant chemotherapy

Reis Krämmer Bárbara , Faviero de Vasconcellos Natália , da Costa Rodrigues Ticiana , Antônio Czepielewski Mauro , Guaragna Filho Guilherme , Cristina Pedroso de Paula Leila

Background: In Brazil, specially in the south, there is a high prevalence of p53 mutations – 1:300 compared to 1:5000-1:20000 incidence worldwide. (1) As a consequence, adrenocortical carcinoma as a cause of virilization in children is much more common in our practice.Clinical Case: M.P.O., a 32-month-old girl, was referred to our institution - Hospital de Clínicas de Porto Alegre - in May 2022 due to progre...

Clitoromegaly as a manifestation of neurofibromatosis type 1

Faviero de Vasconcellos Natália , Reis Krämmer Bárbara , da Costa Rodrigues Ticiana , Antônio Czepielewski Mauro , Guaragna Filho Guilherme , Cristina Pedroso de Paula Leila

Background: Clitoromegaly usually is a sign of virilization, and should lead to prompt evaluation in order to allow adequate treatment. Neurofibromatosis (NF) is a syndrome characterized by pigmentary changes, development of benign tumors of peripheral nerve and increased risk of other malignant tumors.Clinical Case: A five year old female patient was referred to the pediatric clinic of Hospital de Clínicas de Por...

Phenolic Endocrine Disruptors as Potential Risk Factors for Early Onset Thelarche: Insights from a Population-Based Study

Sol Ventura Paula , Escribano Arantxa , Herrero Xavier , Torrebias Meritxell , Corripio Raquel , Castiello Francesca , Riaño Isolina , Olivas Alicia , Suarez Beatriz , Freire Carmen

The diagnosis of early thelarche is common in Pediatric Endocrinology consultations, with many cases lacking an organic cause. It can either spontaneously resolve, remain stable, or progress to precocious puberty. Early exposure to endocrine-disrupting environmental pollutants (EDs) with estrogenic and/or anti-androgenic effects during pregnancy or childhood may affect the timing of thelarche onset and/or puberty in girls. Further research is needed to better understand the in...

Introduction: X-linked hypophosphatemic rickets (XLH) is characterized by a mineralization disorder in the growth plate and cortical and trabecular bones, resulting in bone deformities with anthropometric changes and potential alterations in body composition.Objective: To evaluate the body composition of 12 children and adolescents with XLH compared to healthy controls by anthropometric and densitometry data.<p class...

Exonic Splicing Mutations by Silent Nucleotide Variation in the Androgen Receptor Gene Causes Androgen Insensitivity Syndrome

Loch Batista Rafael , de Santi Rodrigues Andreza , Evilen da Silva Tathiana , Siqueira Cunha Flavia , Lisboa Gomes Nathalia , Rodrigues Daniela , Domenice Sorahia , Frade Costa Elaine , Bilharinho de Mendonca Berenice

Background: Androgen Insensitivity Syndrome is a common form of 46,XY DSD. In the literature, 85–90% of patients with complete form of Androgen Insensitivity (CAIS) and 30% of patients with parcial form (PAIS) have the AR gene mutation identified, In most cases are found a missense mutation with aminoacid change. Mutations without aminoacid changes (silent mutations) are rarely related to human diseases and have never been identified in patients with CAIS.<p class="ab...

Premature Infants Born Small by Gestational Age: the Role of Insulin-like Growth Factor-1 in the Regulation of Postnatal Growth

Kovalenko Tatyana , Yuditskiy Anton , Petrova Irina

The role of insulin-like growth factor-1 (IGF-1) in the regulation of growth of children with intrauterine growth is currently being discussed, but the final point of view has not been achieved.Aim: to study the effect of IGF-1 in the dynamics of postnatal growth of premature infants with SGA in the first 5 years of life.Material and Methods: The prospective study included prematurity with SGA (gro...

Premature Infants Born Small to Gestational Age: Growth Dynamics in the First 5 Years of Life

Yuditskiy Anton , Kovalenko Tatyana , Petrova Irina

Prematurity combined with intrauterine growth retardation (small to gestational age, SGA) is a potential risk factor for adverse growth prognosis. There is insufficient evidence on this issue.Aim: to study the growth rates in preterm infants born small to gestational age, different gestational age in the first 5 years of life.Material and Methods: The prospective study included preterm infants with...

Growth of Premature Infants Born Small by Gestational Age

Kovalenko Tatyana , Yuditskiy Anton , Petrova Irina

Premature infants born small by gestational age (SGA) represent a potential cohort for growth retardation. However, up to the present time, questions of the frequency and severity of the growth deficit, the timing of the growth rate, the age of achievement of the population standard depending on the gestational age have been discussed.Aim: To assess the dynamics of growth of preterm infants born small by gestational age within 5 years of life, taking int...
