The girls had to meet the conditions of having experienced the minimu...
Background: The first step in assessment of children with precocious puberty is to determine whether the cases are of benign nature or have more serious causes. It seems that two criteria of "height age" and "bone age" are helpful for this decision. Materials and Methods: To evaluate the usefulness of those criteria, a retrospective study of 74 children (50 girls and 24 boys) with precocious pu...
The effects of feeding level on body weight (BW), lifetime growth rate, backfat thickness (BF), fatness (BF/BW) and ovulation rate at first (puberty) and second estrus were examined in 145 gilts. From 47.2 kg until puberty, gilts were fed 2.0 kg/d (L) or had ad libitum access to feed (H). From puberty to second estrus, the feed allowance of one-half of the L gilts was increased to 2.8 kg/d. Flu...
Managerial and economic efficiencies of cattle reproduction systems that are seasonal in nature are most likely to benefit from having a compact calving season. Effective replacement heifer development is a critical segment of the integrated management program in an efficient beef cow production system. The replacement heifer represents the future profitability and genetic improvement of the co...
Precocious puberty results mostly from the precocious activation of the gonadotropic axis. Although the age limits have recently been discussed, most physicians consider that onset of pubertal development before the age of 8 years in a girl or 9 years in a boy warrants at least a clinical and bone age evaluation by a paediatric endocrinologist. The major concern in precocious puberty is the und...

Recent developmental cognitive neuroscience research has supported the notion that puberty and adolescence are periods of profound socio-emotional development. The current study was designed to investigate whether the onset of puberty marks an increase in the awareness of complex, or "mixed," emotions. Eighty-three female participants (aged 9-16 years) were divided into three groups according t...
PURPOSE Serum alkaline phosphatase (ALP) level is the most valid marker of bone formation. Precocious puberty (PP) in girls is characterized by early growth acceleration. The aim of this study was to determine whether serum ALP levels differ between girls with PP and those with normal puberty, and whether ALP level varies with age or Tanner stage. METHODS This retrospective study included gir...

In general, precocious puberty can be classified as central or peripheral. This is a retrospective hospital-based study was conducted at King Khalid University Hospital (KKUH), Riyadh, Saudi Arabia, during the period January 1990 and December ...
