Background: Maternal diabetes is a pathologic state that increases the incidence of complications in both the mother and the foetus. Patients with diabetes mellitus (DM) may exhibit reproductive abnormalities, including PCOS and hypogonadotropic hypogonadism. Diabetes during pregnancy is an endocrine disruptor and studies performed in animal models have shown abnormalities in gonadal function in the offspring, but it is unknown whether pre-gestational (PGDM) and gestational di...

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...

Introduction: Kisspeptin stimulates the gonadotropin releasing hormone (GnRH) neurons in hypothalamus initiating puberty. However, it is not known whether GnRH inhibits kisspeptin secretion by negative feedback and whether there are any associations between circulating levels of kisspeptin and other hormones, like ghrelin, important for the onset of puberty.Methods: Thirteen girls with suspected central precocious pubert...

Background: Papillary thyroid cancer has been described in three patients with Turner syndrome (TS) who received growth hormone therapy (Cabanas P, 2005; Bautembach-Minkowska J, 2018). We are presenting a case of papillary thyroid cancer in a girl with a late-diagnosed Turner syndrome who has not received any hormonal therapy up to 17 years.Clinical case: A girl was diagnosed with TS syndrome (karyotype 45XO/46X i(X)q) a...

Aim: To study the incidence of childhood thyrotoxicosis in five counties in central Sweden during 1990–2009 and to study the treatment outcome.Methods: Children below the age of 16 years diagnosed with thyrotoxicosis during the 20-years period and living in the study area were identified retrospectively. Data on the total number of children below 16 years of age living in the area during the study period was collected from the National Board of Stat...

Introduction: Delayed puberty is defined as the absence of physical signs of puberty by the age of 14 years in boys and 13 years in girls. According to this definition, the prevalence of delayed puberty would be 2%, if the ages of pubertal onset were normally distributed in the population. However, the prevalence or incidence of delayed puberty has not been described before, as far as we know. Our aim was to study the incidence of delayed puberty in central Sweden.<p class...

Introduction: Ghrelin is a growth hormone-releasing acylated peptide stimulating the appetite, mainly produced in the stomach, and with an important role in pubertal development (1). Two ghrelin forms have been described, acylated (AG) and desacylated (DAG), but it is debated whether DAG is an active hormone or a degradation product of AG (2). Our aim was to evaluate the effects of adding the protease inhibitor 4-(2-aminoethyl) benzenesufonyl fluoride hydrochl...

Background: Medulloblastoma is the most common malignant pediatric brain tumor. Although survival has improved with oncological therapy, late effects such as endocrine consequences are common, especially growth failure and thyroid dysfunction.Methods: Children diagnosed with medulloblastoma in a pediatric hospital between 2004 and 2014 were studied and followed until 2019. Statistical analysis was performed to estimate t...

Background: Growth hormone (GH) treatment is indicated for children who are born small for gestational age (SGA) and fail to achieve sufficient catch-up growth during infancy and remain short throughout childhood.Aims: To evaluate the effect of GH treatment in a large, multicentric, Portuguese SGA children cohort and to analyze for correlation between GH treatment response and clinical factors.<str...

Background: Neurofibromatosis type 1 (NF1) caused by loss of function mutation in the NF1 gene; leads to the hyperactivation of RAS and its downstream mediators and contributes to tumour formation. The main manifestations of NF1 are café au lait macule, axillary and/or inguinal freckling. Neurofibroma plexiform is specific for NF1 and identified on the face and trunk. Urogenital presentation is infrequent in the penis. Identification of this lesion is essential because it...
