The effect of a GnRH analogue injection on the circulating levels of kisspeptin-1 in girls with suspected central precocious puberty

Rodanaki Maria , Rask Eva , Lodefalk Maria

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...

Papillary Thyroid Cancer in a 17-Years Old Girl with a Late-Diagnosed Turner Syndrome

Pankratova Maria , Brovin Dmitriy , Kareva Maria

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...

Incidence and Treatment Outcome of Childhood Thyrotoxicosis

Rodanaki Maria , Lodefalk Maria , AEman Jan

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...

Incidence of Delayed Puberty in Adolescents. A Population-Based Study in a County in Central Sweden

Rodanaki Maria , Rask Eva , Lodefalk Maria

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...

Adding a protease inhibitor to sampling tubes increases the acylated ghrelin and decreases the desacylated ghrelin levels in girls.

Rodanaki Maria , Rask Eva , Lodefalk Maria ,

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...

Acrodysostosis: a case report

Pitea Marco , Crocè Ludovica , Sala Elisa , Lanzafame Ruggero , Mora Stefano

A 2.6-year-old girl of Egyptian origins comes to our attention due to a deflection of the growth rate. The girl was born small for gestational age (SGA), and is affected by congenital hypothyroidism, with normal sized thyroid, treated with Levothyroxine. At the age of 1.8, due to right lameness, an x-ray of pelvis and lower limbs was performed, as indicated by the orthopaedic. The examination showed absence of the distal tibial ossification nucleus in the right leg and entangl...

Craniosynostosis in hypophosphatasia

Pitea Marco , Sala Elisa , Ruggero Lanzafame , Crocè Ludovica , Mora Stefano

Hypophosphatasia (HPP) is a rare genetic disease caused by mutations with loss of function in the ALPL gene, which encodes for non-specific tissue alkaline phosphatase (TNSALP). We report a case of infantile hypophosphatasia. Due to positive family history for hypophosphatasia, a chorionic villus sampling was made, with evidence in composed heterozygous of variants c.407G>A and c.1489T>C in the ALPL gene. At birth the patient did not have clinical complications, however ...

AgRP neurons mediate sex differences in response to the activity-based anorexia model

Consolata Miletta Maria

Anorexia nervosa (AN) is a multifaceted and debilitating illness characterized by self-induced starvation, persistent anxiety about weight gain, preoccupation with body image, and maladaptive food choices. It is characterized by the disruption in homeostatic energy balance mechanisms and the persistence of homeostatic hunger is overridden by dysfunctional self-regulatory and reward pathways that drive food aversion and severely restrict food intake. Epidemiological studies hav...

MEN1 in Children and Adolescents

Brandi Maria Luisa

Background: MEN1 is an autosomal dominant disorder that is due to mutations in the tumor suppressor gene MEN1, which encodes a 610-amino acid protein, menin. MEN1 is characterized by the occurrence of parathyroid, pancreatic islet, and anterior pituitary tumors. The prognosis for MEN1 patients might be improved by presymptomatic tumor detection and undertaking treatment specific for MEN1 tumors.Objective and Hypotheses: Genetics is increasingly becoming ...
