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...

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...
