ABSTRACT Objective: To describe the follow-up of girls with peripheral precocious puberty (PPP) due to McCune-Albright syndrome (MAS). Subjects and methods: Data from 18 females, including anthropometric and reproductive outcomes, were evaluated. Genetic analysis was performed on DNA from peripheral leukocytes via digital PCR. Results: Clinical manifestations of PPP were isolated thelarche, thelarche plus vaginal bleeding, or isolated vaginal bleeding in 44.5%, 33.3%, and 22.2%, respectively, at an early age (3.3 ± 1.6 years). At diagnosis, basal LH and FSH […]

ABSTRACT Objective: Fibrous dysplasia (FD) is a rare bone disorder that can involve any part of the skeleton, leading to bone pain, deformities, and fractures. Treatment with intravenous bisphosphonates has been used with variable results. Therefore, we aimed to evaluate the effects of zoledronic acid (ZA) therapy in patients with monostotic or polyostotic FD. Subjects and methods: The medical records of thirteen patients with FD evaluated between 2015 and 2020 were retrospectively analyzed. In the subgroup of patients treated with […]

OBJECTIVES: The use of drug therapy based on cabergoline, octreotide and long-acting release (LAR) octreotide has presented varying results in the treatment of GH excessive production in patients with McCune-Albright Syndrome. METHODS: We report the case of a 29 year-old female patient presenting McCune-Albright Syndrome and complaint of excessive bone growth. RESULTS: The patient presented a pituitary adenoma involving the right internal carotid artery and excessive secretion of growth hormone (no GH suppression was observed after the oral glucose tolerance […]

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 through basal and GnRH-stimulated LH levels shows activation of the gonadotropic axis. Gonadotropin-independent precocious puberty (GIPP) is the result of the secretion of sex steroids, independently from the […]
