OBJECTIVES This review was aimed at determining the imaging findings in patients with precocious puberty. RESULTS Within a period of 8 years (from 2002 to 2010) there were 53 patients diagnosed with precocious puberty. Out of the 53 patients, 37 had undergone diagnostic imaging to detect the possible organic causes of precocious puberty. Imaging findings were positive in 31 patients and out o...
OBJECTIVE To evaluate the contribution of prepubertal childhood body mass index (BMI) and BMI change through puberty and adolescence, 2 distinct developmental BMI parameters, for risk of adult stroke in men. METHODS In this population-based study in Gothenburg, Sweden, men born in 1945-1961 with information on both childhood BMI at age 8 and BMI change through puberty and adolescence (BMI at ...
Puberty is characterized by hormonal, physical and psychological transformation. The human brain undergoes significant changes between childhood and adulthood, but little is known about how puberty influences its structural development. Using a longitudinal sample of 711 magnetic resonance imaging scans from 275 individuals aged 7-20years, we examined how subcortical brain regions change in rel...
Precocious puberty constitutes a significant clinical problem due to psychological implications and health concerns as well as consequences associated with girls' fertility. Self-acceptance, peer approval, early motherhood and future fertility - these are only a few issues associated with puberty, the disorders of which may have a negative influence on personality and health. The role of imagin...
Changes in puberty timing have implications for the treatment of individual children, for the risk of later adult disease, and for chemical testing and risk assessment for the population. Children with early puberty are at a risk for accelerated skeletal maturation and short adult height, early sexual debut, potential sexual abuse, and psychosocial difficulties. Altered puberty timing is also o...
BACKGROUND Central precocious puberty (CPP) is characterized as increasing gonadotropin-releasing hormone (GnRH) release. Orexin-A has also been shown to affect GnRH release. However, there are few reports about the effect of orexin A on the treatment of CPP. METHODS After establishing the precocious puberty model, the rats were divided into four groups: normal control, precocious puberty rat...
BACKGROUND The onset of puberty is first detected as an increase in pulsatile secretion of gonadotropin-releasing hormone (GnRH). Early activation of the hypothalamic-pituitary-gonadal axis results in central precocious puberty. The timing of pubertal development is driven in part by genetic factors, but only a few, rare molecular defects associated with central precocious puberty have been ide...
The aetiology of 197 girls and 16 boys presenting with sexual precocity was reviewed. Ninety one girls and four boys had central precocious puberty (M:F 23:1); a cause was identified in all the boys but in only six girls. All boys with precocious puberty need detailed investigation; in girls investigation should be based on clinical findings, particularly the consonance of puberty.
Appearance of secondary sexual characteristics before 9 years of age in boys constitutes precocious puberty(l). There are three major types of sexual precocity: true or central, peripheral and combined peripheral and central. Precocious puberty may be isosexual or heterosexual in nature. In this communication we report a case of meningomyelocele who developed isosexual precocious puberty second...
We report a girl with a de novo distal deletion of 9p affected by idiopathic central precocious puberty and intellectual disability. Genome-wide array-CGH revealed a terminal deletion of about 11 Mb, allowing to define her karyotype as 46; XX, del(9)(p23-pter). To our knowledge, this is the second reported case of precocious puberty associated with 9p distal deletion. A third case associates pr...
