Presentation
Extensive imaging of the CNS for patients presenting with CPP is recommended. [thejns.org]
Case presentation. We present the case of a 15-month-old Asian male baby who presented with precocious puberty associated with hepatoblastoma. [mdanderson.elsevierpure.com]
We present here a rare case of a 7-month-old infant girl with CPP and HH who was successfully treated with depot gonadotropin-releasing hormone (GnRH) analogue is presented. [ncbi.nlm.nih.gov]
Entire Body System
- Precocious Puberty
Central precocious puberty in these children might follow extensive sex steroid exposure due to the peripheral precocious puberty induced by the activating mutation of the Gs protein gene. [ncbi.nlm.nih.gov]
Two types of precocious puberty include the following: Gonadotropin-dependent precocious puberty. [stanfordchildrens.org]
E-mail: [email protected] The term Precocious puberty refers to the appearance of pubertal signs at an earlier age than established standard. Precocious puberty may be central or peripheral. [jcdr.net]
- Accelerated Growth
At the age of 1 year, our patient presented with increased testicular volume for his age, bone age advancement and growth acceleration. [ncbi.nlm.nih.gov]
[…] of 9: Penile enlargement Testicular development Increased muscle development Voice change Growth of body hair Accelerated growth There are two types of precocious puberty: Central precocious puberty (CPP). [rileychildrens.org]
Precocious puberty Puberty is a complex biological process involving sexual maturation and accelerated growth. These processes normally initiate when pulsatile secretion of gonadotropin-releasing hormone (GnRH) from the hypothalamus begins. [imprinting-disorders.eu]
Early puberty accelerates growth. These children may initially be considerably taller than their peers. Because bone maturation is also accelerated, growth may be completed at an unusually early age, resulting in short stature. [emedicine.medscape.com]
- Cushingoid
No cushingoid stigmata, mucocutaneous hyperpigmentation, café au lait macules, bony deformities or palpable abdominal lump were noted on clinical examination. [casereports.bmj.com]
- Poor Growth
Poor growth potential is further affected by central precocious puberty (CPP) which is frequent in these patients. [ncbi.nlm.nih.gov]
Skin
- Acneiform Eruption
They denied any history of acneiform eruptions, malodorous secretions, deepening of voice, muscular prominence or rapid height and weight gain in the child. [casereports.bmj.com]
Face, Head & Neck
- Neck Swelling
There was no clitoral enlargement, neck swelling, pigmented skin marks, bone pain/fractures. Parents could not comment on any recent height gain. She had no significant medical illness or radiation exposure in the past. [ijem.in]
Urogenital
- Scrotal Mass
No history of headache, blurring of vision, seizures, cranial irradiation, perinatal trauma, past encephalitis, exogenous exposure to sex steroids, mucocutaneous hyperpigmentation, salt wasting crisis, lump abdomen, scrotal mass, bony pains, bony deformities [casereports.bmj.com]
- Imperforate Hymen
Imaging also revealed imperforate hymen, vaginal atresia, and mucocolpos. [ncbi.nlm.nih.gov]
Workup
Laboratory workup revealed Serum Sodium 138 mmol/L (Ref Values: 135-145), Serum Potassium 4.1 mmol/L (Ref Values: 3.5-5.0), Serum Chloride 101 mmol/L (Ref Values: 97-106). [sciedupress.com]
When should you start a workup? What should you order and when do you refer to endocrinology? We discuss these things and more with our pediatric endocrine consultant. [hippoed.com]
Subsequent laboratory workup demonstrated highly elevated hormone levels: LH = 1.38 mIU/ml (normal < 0.7), and testosterone = 164 ng/dl (normal < 9.0). Additionally, bone age was advanced, at 11 years. [thejns.org]
Footnotes Contributors: PKS and KSGS contributed to the clinical diagnosis, initial laboratory workup and treatment. [ncbi.nlm.nih.gov]
Treatment
Ht and HtSDS after treatment were positively correlated with the predicted Ht (PAH) before treatment and negatively correlated with the bone age/statural age ratio before treatment (p < 0.05). [ncbi.nlm.nih.gov]
Prognosis
All previously reported cases in the literature are old and prognosis was grim. Case presentation. We present the case of a 15-month-old Asian male baby who presented with precocious puberty associated with hepatoblastoma. [mdanderson.elsevierpure.com]
The patient did not receive medical care for his precocious pubertal development, because of adequate height prognosis, and reached normal height for both his target height and Klinefelter patients. [ncbi.nlm.nih.gov]
What is the prognosis of central precocious puberty? Similar to the treatment of central precocious puberty, the prognosis is related to the precise cause of the child's disease. [rxlist.com]
The prognosis otherwise depends on the underlying cause [patient.info]
Etiology
Location Indianapolis, IN Subject Area Pharmacy, Health Sciences & Exercise Science Start Date 11-4-2014 8:30 AM End Date 11-4-2014 10:00 AM Description Background: Precocious puberty is a relatively rare disease with little documented information on etiology [digitalcommons.butler.edu]
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. [ncbi.nlm.nih.gov]
Epidemiology
OBJECTIVES: Precocious puberty seems to be increasing but epidemiological data are scarce. Our objective was to improve the epidemiologic knowledge on this disease. [ncbi.nlm.nih.gov]

Summary Epidemiology The prevalence of CPP has been evaluated at approximately 1/ 500 girls and 1/ 2,000 boys in Denmark. Girls are more affected than boys, with an overall male to female ratio of at least 1:10. [orpha.net]
The epidemiology of CPP is somewhat nebulous, with a commonly cited prevalence range of 1 in 5000 to 1 in 10,000 children 7. CPP is known to occur more frequently in girls than in boys and has different predominant causes for each sex. [endo.com]

Prevention
Treatments exist to help prevent the onset of puberty, as well as other medications that prevent individuals from sexually developing. [diseaseinfosearch.org]
