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...

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...

The up-regulation and down-regulation of gonadotropin-releasing hormone (GnRH) in central precocious puberty is not yet known. However, recent advances in neuroendocrinology have shown the controlling role of arginine-phenylalanine RF-amide-related peptides (RFRPs) on GnRH secretion in different phenomenon of reproduction such as estrus cycle and pregnancy, but the exact role of RFRPs in pubert...

Hypothyroidism is usually associated with delayed pubertal development but in rare occasions precocious puberty may ensue which is seen in cases of prolonged and untreated hypothyroidism. This is also called the Van Wyk Grumbach syndrome. Here we present 4 cases of precocious puberty due to hypothyroidism.

Precocious puberty refers to the appearance of physical and hormonal signs of pubertal development at an earlier age than is considered normal. In girls, the telltale signs of precocious puberty include any of the following symptoms before 7 or 8 years of age: breast development, pubic or underarm hair development, rapid height growth a growth "spurt", onset of menstruation, acne and "mature" b...

Central precocious puberty (CPP) is characterized by the same biochemical and physical features as normally timed puberty but occurs at an abnormally early age. Most cases of CPP are seen in girls, in whom it is usually idiopathic. In contrast, ~50% of boys with CPP have an identifiable cause. The diagnosis of CPP relies on clinical, biochemical, and radiographic features. Untreated, CPP has th...

We present a five year old boy with central precocious puberty and pineal gland cyst on neuroimaging. This association is uncommon and highlights the role of pineal gland in puberty.

PURPOSE The progressivity of central precocious puberty (CPP) seems to depend on the age at presentation. We evaluated the clinical courses of CPP girls according to their age at initiation of treatment. METHODS One hundred thirty five girls with CPP diagnosed between Jan. 2003 and Dec. 2009 and regularly followed for more than one year were included. They were treated with gonadotropin-relea...

Precocious puberty is a rare condition characterized by the development of secondary sexual characteristics before the median age for the sex. It is either gonadotropin dependent also called as central or gonadotropin independent also known as peripheral type. Hypothalamamic Hamartoma is a common cause of the central or precocious puberty due to organic brain lesion. Here we present a two year ...
