Background: Transient neonatal hypoparathyroidism (hPT) by inhibition of fetal parathyroid secondary to undiagnosed asymptomatic hyperparathyroidism (HPT) in the mother often debuts as late neonatal seizures.Objective and hypotheses: To emphasise the indication of maternal metabolic study (Cacium-Ca-, Phosphorus-P- and PTH) in addressing late neonatal hypocalcemia, especially in the case of late neonatal hypocalcemic seizures.Metho...

Background: Polyuria and polydipsia syndrome (PPS) workup is not straightforward, especially in children. Basal investigations are often not reliable in distinguishing among diabetes insipidus (DI), central (CDI) or nephrogenic (NDI), and primary polydipsia (PP). Water deprivation test (WDT) is often essential, although uncomfortable and not always reliable enough to recognize partial DI. Plasma AVP investigation is not routinely used in the diagnostic pathway...

Background: The pseudohypoparathyroidism (PHP) encompasses a heterogeneous group of clinical entities caused by a defect in the peripheral action of parathyroid hormone (PTH). Biochemically it manifests itself with hypocalcemia, hyperphosphatemia and elevated PTH. PHP-Ia is the most frequent and multiple hormone resistance, associated signs of Albright hereditary osteodisfrofia (OHA) and mutations in the gene encoding GNAS Gsa protein.Case presentation: ...

Objective: Advanced glycation end products (AGEs) increased oxidative stress and promote inflammation, resulting in the cellular damage, by interacting with their receptor (RAGE) on cell membrane. By contrast, the soluble receptor for AGE (sRAGE), that is proteolytically cleaved from cell surface receptor via matrix metalloproteinases, sequester RAGE ligands and act as a cytoprotective and anti-inflammatory agent. AGEs-RAGE/sRAGE interaction is deemed to play a role in the pat...

Background: Loss-of-function mutations of the androgen receptor (AR) gene result in androgen insensitivity syndrome (AIS) in 46,XY individuals, causing a disorder of sex development. AIS has a clinical continuum according to the resistance severity, being classified into three main categories: complete (CAIS), partial (PAIS), and mild (MAIS). The authors present a female phenotype patient with CAIS.Case Report: An otherw...

Background: Turner syndrome (TS) patients typically exhibit short stature and gonadal dysgenesis with pubertal delay and infertility. Up to 30% of these girls will have spontaneous pubertal development, however only 2% achieve a spontaneous pregnancy. Biochemical markers reflecting the ovarian reserve in girls and adolescents with TS are therefore needed.Objective and hypotheses: Evaluation of the ovarian reserve in girls and adolescents with TS using se...

Background: C-peptide secretion is the most accurate measurement of residual β-cell function in type 1 diabetes (T1D) and even residual levels seem to positively correlate with a lower probability of complications.Objective and hypotheses: Identify key determinants to the evolution of the β pancreatic cell function, measured by fasting C-peptide (FCP).Method: Prospective study of patients diagnosed with T1D, with evaluati...

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...

Background and Aims: In light of the recent evidence suggesting an increase in idiopathic central precocious puberty (ICPP) cases during the COVID-19 pandemic, this study aimed to assess the proportion of patients referred for precocious puberty (PP) and, within this group, the number of ICPP cases diagnosed before and during the pandemic. Additionally, we compared the demographic, anthropometric, and clinical characteristics of ICPP patients between the two g...

Background and Aims: Klinefelter syndrome (KS) is the most common chromosomal abnormality in men, but because of its highly variable phenotype and clinical unawareness, it remains largely under-diagnosed. Cardinal features include tall stature, gynecomastia, hypergonadotropic hypogonadism, azoospermia and infertility. Learning and behavioral problems are also common. Testosterone replacement therapy (TRT) helps to prevent or ameliorate many of the comorbiditie...
