Methods Clinical Records of 17 children (16 girls and 1 boy) were retrospectively analyzed over a period of 24 months (Mar 2012 to Mar 2014). All children satisfied the criteria for precocity based on clinical features, radiological assessment and GnRHa stimulation test. All 16 girls had idiopathic precocious puberty and the only boy had hypothalamic hamartoma. The mean age of presentation was ...

PURPOSE Vitamin D deficiency has been linked to chronic diseases, such as diabetes mellitus, obesity and autoimmune disease. However, data on the vitamin D status and its association with precocious puberty in girls are limited. We aimed to investigate the association between serum 25-hydroxyvitamin D (25OHD) and precocious puberty in girls. METHODS A total of 60 girls with central precocious...

Hypothalamic hamartoma (HH) is a rare intracranial lesion that usually presents with classic triad of central precocious puberty, gelastic epilepsy, and developmental delay. Herein, a 14-year old boy is presented in whom the diagnosis of HH was made by magnetic resonance imaging. While he did not have any complain of precocious puberty, he surprisingly suffered from delay in puberty. The defini...

Forty-three children with precocious puberty related to central nervous system (CNS) lesions were examined. Plasma concentrations of estradiol in the females and testosterone in the males were obtained. Panoramic radiographs were used to assess dental root and crown development. All mandibular canines, premolars, and molars were included which could be visualized without apparent distortion. De...

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...

Excitatory amino acids, glutamate in particular, have a marked stimulatory effect on the reproductive axis, particularly at puberty. Glutamate, N-methyl-D-aspartate (NMDA), and kainate stimulate gonadotropin-releasing hormone (GnRH) secretion in immature mammals and NMDA receptor stimulation results in precocious puberty in rats and monkeys. Puberty is characterized by an increased sensitivity ...
