Insights
Girls with idiopathic precocious puberty (IPP) show accelerated growth from birth. This early growth pattern can aid in diagnosing IPP in pediatric endocrinology.
Area of Science:
- Pediatric Endocrinology
- Growth and Development
- Puberty Disorders
Background:
- Idiopathic precocious puberty (IPP) is a condition where puberty begins earlier than normal.
- Understanding the growth patterns associated with IPP is crucial for timely diagnosis and management.
- Early detection of IPP can prevent potential long-term health issues.
Purpose of the Study:
- To characterize the growth trajectory of girls diagnosed with idiopathic precocious puberty from birth to diagnosis.
- To identify specific growth patterns that may serve as early indicators of IPP.
- To compare the growth patterns of girls with IPP to those of healthy controls.
Main Methods:
- A retrospective study involving 47 girls with IPP and 35 age-matched controls.
- Collection of height data from birth until diagnosis from personal health records.
- Calculation of Height Standard Deviation Scores (HSDS) and Body Mass Index Standard Deviation Scores (BMI SDS) at various ages.
Main Results:
- Girls with IPP exhibited a significantly increasing HSDS from birth (-0.01) to diagnosis (1.23) (P < .001).
- Control girls showed stable HSDS values throughout childhood, with no significant changes observed.
- No significant differences in BMI SDS were found between the IPP group and the control group.
Conclusions:
- The distinct early growth acceleration pattern observed in girls with IPP can serve as a valuable diagnostic clue.
- Monitoring growth patterns, particularly HSDS, is important for identifying potential cases of IPP.
- This finding supports the integration of growth assessment into the diagnostic workup for precocious puberty.
Objective:
To determine the growth pattern of girls with idiopathic precocious puberty (IPP) from birth until diagnosis.
Study Design:
We studied 47 girls with IPP and 35 control girls. In each subject, height and weight were measured at diagnosis, whereas data on height from birth until diagnosis were taken from the personal health book of the patient. Height standard deviation score (HSDS) and body mass index SDS were calculated.
Results:
Mean age (+/-SD) of the girls with IPP was 7.6 (1.1) years and of control girls was 7.5 (0.9) years. At birth, HSDS of the patients with IPP was -0.01 (0.8); at the age of 2 years, 0.42 (1.2); at the age of 4 years, 0.64 (1.1); and at diagnosis, 1.23 (1.7) (P < .001). HSDS of control girls was 0.02 (0.8) at birth, 0.25 (0.8) at 2 years, 0.12 (0.9) at 4 years, and 0.19 (1.1) at assessment (P > .05). There was no statistical difference between body mass index SDS of the patients 0.6 (1.1) versus that of control girls 0.5 (1.0).
Conclusions:
The early growth acceleration pattern may be used as an additional clue to the diagnosis of idiopathic precocious puberty.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
