The present study investigated how pubertal development and sex interact to influence humans' emotion susceptibility during adolescence. Event-related potentials were recorded for highly emotional, mildly emotional and neutral stimuli in positive and negative blocks, when 73 adolescents (36 pre-/early pubertal students, 19 boys, 10-12 years old; 37 mid-/late pubertal students, 18 boys, 11-13 ye...

Results Case 1) A 9.4-year-old boy presented with bilateral testicular enlargement accompanied by other pubertal signs. His bone age was 11 years and serum levels of LH and FSH after GnRH stimulation were within pubertal limits. Scrotal ultrasonography (US) showed TM in both testes. He revealed early puberty and no malignant evolution. Case 2) A 9.4-year-old boy with Down syndrome presented wit...

Concerns about possible early pubertal development are a common cause for referral to pediatric medical subspecialists. Several recent studies have suggested that onset of breast and/or pubic hair development may be occurring earlier than in the past. Although there is a chance of finding pathology in girls with signs of puberty before 8 years of age and in boys before 9 years of age, the vast ...

Medical journals and popular media present early-onset puberty as a source of substantial parental, medical, and social concern—even a crisis. An article written by parents and a related editorial commentary in Archives of Disease in Childhood, for example, describe the condition as “devastating” and “frightening”, and suggest that clinicians often fail to adequately support affected families. ...

BACKGROUND There is a large increase in back pain reporting in the early teens. In no previous study has the prevalence of low back pain been investigated in relation to the onset of puberty. The objective of this study was to establish whether the onset of puberty is associated with back pain reporting in young girls. METHODS A subsample of 254 girls aged 8-10 years and 165 girls aged 14-16 ...

Adopted children show more problem behaviors than nonadopted children. Given that internationally-adopted individuals show earlier puberty than non-adopted individuals, and early puberty is associated with problem behaviors in nonadopted youth, we analyzed data from domestic adoptees to determine whether problem behaviors could be explained by differences in pubertal timing. Relative to nonadop...
