Prepubertal exposure to low, but elevated levels of manganese (Mn) can induce increased secretions of puberty-related hormones resulting in precocious pubertal development in female rats. These events are due to an action of the element within the hypothalamus to induce the secretion of gonadotropin-releasing hormone (GnRH). Because of these prepubertal effects of Mn and because precocious pube...

PURPOSE User-created content (UCC) has provided a considerable amount of medical information and become an important source. We aimed to evaluate the quality and scientific accuracy of precocious puberty-related UCC on YouTube. METHODS The keywords "precocious puberty", "early puberty", "sexual precocity", and "precocity" were searched for on YouTube during June and July 2014. More than 1,500...

Precocious puberty associated with profound hypothyroidism is a rare condition. It is usually characterized by breast development, vaginal bleeding, lack of pubic hair and delayed bone age. Multicystic ovaries in profound hypothyroid patients with precocious puberty have been rarely described. Vaginal bleeding in adolescent girls should be considered as a clinical significance particularly when...

There are many etiologies of peripheral precocious puberty (PPP) with diverse manifestations resulting from exposure to androgens, estrogens, or both. The clinical presentation depends on the underlying process and may be acute or gradual. The primary goals of therapy are to halt pubertal development and restore sex steroids to prepubertal values. Attenuation of linear growth velocity and rate ...

Precocious puberty is defined as the development of secondary sexual characteristics before the age of 8 years in girls and 9 years in boys. Gonadotropin-dependent precocious puberty (GDPP) results from the premature activation of the hypothalamic-pituitary-gonadal axis and mimics the physiological pubertal development, although at an inadequate chronological age. Hormonal evaluation, mainly th...

BACKGROUND Precocious puberty may reduce final adult height, and affected children may suffer social and emotional problems. The efficacy of treatment with a long acting agonist analogue of the gonadotropin releasing hormone (aLHRH) has been well demonstrated. AIM To evaluated the efficacy of a new formulation of aLHRH (leuprolide, Lupron) for the suppression of gonadotropin activation and cl...

McCune Albright syndrome is diagnosed by a constellation of Café-au-lait spots, multiostosis fibrous dysplasia and precocious puberty. Other endocrine dysfunctions which are often associated are growth hormone excess, hyperthyroidism, Cushings syndrome, hyperprolactinemia and phosphate wasting. Its prevalence is 1:100000–1:1000000 in different ethnicity [1]. It is a rare cause of precocious pub...

Gonadotropin-releasing hormone analogues are common treatment option in central precocious puberty in childhood as well as in endometriosis, infertility, and prostate cancer in adults. Pseudotumor cerebri is a rare side effect observed in adults. We present the case of a girl with precocious puberty treated with triptorelin acetate who developed pseudotumor cerebri after the 4th dose. She had h...

Despite standard clinical definitions and availability of diagnostic tests for precocious puberty, an intensive and structured investigation is needed in order to diagnose the aetiology in particular cases. A 4-year-old, phenotypically female child was referred to paediatric endocrinology consultation for premature pubarche and thelarche. There was an acceleration of growth velocity with high l...

PURPOSE This study aimed to investigate the influence of gonadotropin releasing hormone agonist (GnRHa) treatment on the weight and body mass index (BMI) of girls who were diagnosed with idiopathic central precocious puberty (CPP) or early puberty (EP). METHODS Patients who were younger than 8 years of age at diagnosis were classified as CPP and patients aged between 8 and 9 years at diagnosi...
