Introduction: Congenital hyperinsulinaemic hypoglycaemia of infancy (CHHI) associates with mutations in known genes in approximately 60% of cases. CHHI and mutations in HNF4A gene are reported in 0.5–2.4% in large series. A case of CHHI with renal Fanconi syndrome (FS) and hepatopathy is presented.Clinical description: Male newborn, gestational age: 38 weeks, weight: 4250 g +2.7 S.D., length: 55 cm +3.29 S.D., ...

Introduction: Developing an acute onset thyroid nodule is rare in children and usually associates with infectious or neoplastic disease; when linked to hyperthyroidism, the most likely diagnosis is toxic adenoma.Clinical description: 9-year-old boy with no relevant medical history was seen at the emergency department for acute cervical pain and tumor involving the left thyroid lobe with no inflammatory signs or history of trauma. Physical examination rev...

To attain sexual competence, all mammalian species go through puberty, a maturational period during which body growth and development of secondary sexual characteristics occurs. Puberty begins with the reawakening of the gonadotropin-releasing hormone (GnRH) pulse generator. Reduction in inhibitory transsynaptic inputs combined with increased transsynaptic and glial excitatory inputs to the GnRH neuronal network are responsible for pubertal activation of GnRH neuro-secretion. ...

Background: Chronic diseases are the main causes of bone mass reduction in childhood and adolescence. Different aspects related to the process of bone acquisition and maintenance may be affected. Studies had point out the presence of bone mass reduction in children and adolescents with HIV infection with association to antiretroviral use, chronological age (CA), weight and serum CD4 T-cell counts. However, others do not.Objective: To evaluate bone minera...

Background: Premature pubarche is the appearance of pubic hair before 8 years in girls and 9 years in boys, being more frequent in girls. Current literature demonstrates associations between premature pubarche and metabolic and cardiovascular diseases.Objective and hypotheses: To evaluate the frequency of cardiovascular disease risk factors in girls with isolated premature pubarche (IPP).Method: Observational study using data from ...

Background: Pregnancy associated plasma protein (PAPP)-A2 is an insulin-like growth factor (IGF) binding protein (BP) protease that regulates IGF-1 availability, affecting postnatal growth. We have recently reported the first mutations in human PAPP-A2 causing short stature and changes in bone size and mineral density. However, the IGF system is involved in diverse physiological functions and to date it is unknown how mutations in PAPP-A2, which significantly reduce f...

Background: Promotion of high pick bone mass is one of the strategies to prevent osteoporosis in adult life. Undergraduate students are still in the age group of mineral acquisition and, therefore, their lifestyle may influence this process. Physical exercise is an important lifestyle characteristic for optimize peak bone mass (PBM).Objective: To evaluate bone mass in undergraduate students with different lifestyle.Methods: Observa...

Background: The 12q14.3q15 microdeletion syndrome is a rare entity of which only 16 new cases have been described to date. The syndrome consists of the association of severe pre- and postnatal growth retardation, proportional short stature, psychomotor retardation and osteopoikilosis. The phenotypic appearance of these patients poses a differential diagnosis with Silver-Russell syndrome, among other entities.Clinical description: A 10-month-old boy was r...

Background: Patients with Klinefelter syndrome (SK) have a 47, XXY karyotype and tall stature as a result of overexpression of the SHOX gene. The case of a patient with peculiar phenotype, microcephaly, proportional short stature and 47, XXY karyotype with a deletion in band p11.3 of one X chromosome is presented.Clinical description: A 2-year, 4 month-old boy was referred for study of growth retardation. The product of a first gestation of 39 weeks of h...

Introduction: Prolonged evolution of an untreated hypothyroidism can lead to thyrotropic cell hyperplasia, which could be indistinguishable from a pituitary macroadnoma on resonance. Differential diagnosis is very important since it allows to avoid aggressive therapeutic behaviors.Case report: We show a 3-year-old girl who, in the context of a study due to psychomotor retardation, borderline head circumference and coarse features, presented in magnetic r...
