BACKGROUND Concerns about psychological distress are often used to justify treatment of girls with precocious puberty, but there is little evidence to support these concerns. The extent to which psychological problems are associated with central precocious puberty (CPP) compared with other forms of early puberty in girls has likewise not been established. METHODS Girls presenting with untreat...

A 7 year old girl with precocious puberty was treated with buserelin, a long acting analogue of gonadotrophin releasing hormone. Spontaneous and stimulated gonadotrophin secretion became prepubertal but returned to pubertal values when buserelin was withdrawn, suggesting that normal sexual maturation should follow cessation of treatment.

Methods We identified 72 girls diagnosed with central precocious puberty, and they were treated with GnRH analogue (GnRHa) to suppress pubertal progression from 1 January 2011 to 31 January 2012. GnRH stimulation tests were done before and 4 weeks after the third dose of the GnRH analogue. Information on clinical manifestations and laboratory data were obtained by reviewing medical records. All...

BACKGROUND/AIMS There are few studies in the literature that have evaluated the etiological factors in boys with central precocious puberty (CPP), and these studies are limited in terms of the sample size. In the present study, we aimed to evaluate the etiological factors in male CPP cases. METHODS One hundred male CPP subjects, aged between 9 months and 10.5 years, were included. The medical...

Leydig cell testicular tumors are very rare in children and cause isosexual precocious puberty. Palpable testicular mass or asymmetric testes are common findings on routine examination. We report on a 5-yr-old boy with a Leydig cell tumor of the testis presented with isosexual precocious puberty but no scrotal palpable mass. To our knowledge, this is the first reported Leydig cell tumor in a bo...

Nonlinear mixed models were used to describe longitudinal scrotal circumference (SC) measurements of Nellore bulls. Models comparisons were based on Akaike's information criterion, Bayesian information criterion, error sum of squares, adjusted R2 and percentage of convergence. Sequentially, the best model was used to compare the SC growth curve in bulls divergently classified according to SC at...

BACKGROUND Little is known about the possible deleterious effects of phthalate exposure on endogenous sex steroid levels in children. OBJECTIVE Our objective was to investigate whether urinary phthalate metabolite levels are associated with circulating adrenal androgen levels and age at puberty. METHODS This was a longitudinal study of 168 healthy children (84 girls) examined every 6 months...

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...

Recent studies show an association between the presence of Ureaplasma urealyticum in tracheal aspirates and bronchopulmonary dysplasia. We hypothesized that among infants with birth weights < or = 1,250 g and respiratory disease, those with U. urealyticum in their tracheal aspirates would have radiographic evidence of more-severe pulmonary disease more often than would those without this organi...
