Abstract
BACKGROUND Ovarian enlargement is one of several findings of pathology, including ovarian torsion. With increasing use of MRI for acute abdominal pain in children, data for normal ovary size and appearance are needed. OBJECTIVE To provide preliminary data on normal sizes of ovaries on MRI in pediatric patients. MATERIALS AND METHODS This retrospective IRB-approved study included girls (5 to 17 years of age) with MRI examinations performed for indications not related to the ovaries from 2018 to 2022. For each MRI, coronal T2-weighted single shot fast spin echo and axial T2-weighted fat-saturated images were independently reviewed by three pediatric radiologists who recorded ovary visualization and ovarian linear measurements (3 planes). Ovarian volumes were calculated from linear measurements. Agreement among observers was calculated using kappa statistics and intraclass correlation coefficients. RESULTS A total of 181 MRIs were reviewed. The left ovary was visualized in 166-176 (92-97%) cases (R1-R3) and the right ovary was visualized in 165-174 (91-96%) cases with excellent agreement among reviewers (left: K = 0.89 [0.84-0.94], right: K = 0.85 [0.79-0.91]). Interrater class coefficient (ICC) for largest single dimension of the ovary was left: 0.83 (CI 0.79-0.87) and right: 0.85 (CI 0.81-0.89). There were significant moderate to strong correlations between ovarian volume and age (left: 0.67 [0.58-0.75], right: 0.66 [0.57-0.74]). CONCLUSION The ovaries can be adequately visualized and measured on MRI with excellent inter-reader agreement. This study serves as the foundation for developing normative values for ovarian volumes by age on MRI.

Front Endocrinol (Lausanne) 2024; 15:1314752. [PMID: 38327564 PMCID: PMC10847246 DOI: 10.3389/fendo.2024.1314752] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 01/04/2024] [Indexed: 02/09/2024] Open
Abstract
Precocious puberty is diagnosed when pubertal characteristics appear before the age of 8 years in females. The most common form is gonadotropin-dependent, called axial. The primary method of treatment is administration of gonadotrophin-releasing hormone analogues (GnRHa). The aim of the study was to verify hypothesis that GnRHa therapy in the childhood may be of additive risk factor for polycystic ovary syndrome (PCOS) in adulthood. Material and Methods The study group consists of 24 women (median age 22 88 years, median BMI 23.5) treated with GnRHa for central precocious puberty in childhood. The control group includes 40 women (median age 23 years, median BMI 25.6) diagnosed with isolated premature thelarche and not using GnRHa in the childhood. Anthropometric measurements, ultrasound examination of minor pelvis and hormonal profile were performed. PCOS diagnosis was based on Rotterdam criteria. Results The study confirmed a higher prevalence of PCOS in the study group (50%) than in the control group (10%); p=0.0006. Significant, linear correlation between free testosterone levels and ovarian size was found in the study group (R=0.45 p= 0.03). Conclusions GnRHa therapy during childhood may have a potential influence on incidence of PCOS in the adulthood. Therefore, in this group of patients long-term follow-up focused on screening for PCOS would seem beneficial.

Abstract
Background There is conflicting evidence regarding an association between gonadotropin releasing hormone analogue (GnRHa) therapy and polycystic ovary syndrome (PCOS). This study aimed to compare the prevalence of endocrine disorders, primarily PCOS, between women who had been treated with GnRHa for central precocious puberty (CPP) and those who were not treated. Methods This was a retrospective cohort study, including women diagnosed with central precocious puberty between 1989 and 2011 in a university affiliated tertiary medical center. Data collected included demographic data, medical background, clinical presentation at diagnosis and duration of treatment (zero for non-treated). Gynecologic and endocrine long-term outcomes were compared by treatment group. Results Fifty-one women were included in the study, 27/51 had been treated with gonadotropin releasing hormone analogue (GnRHa). Overall prevalence of PCOS was 19.6%. No statistically significant difference in prevalence of PCOS was demonstrated between the treated and non-treated groups. Similarly, overall prevalence of either clinical or laboratory hyper-androgenism, was 29.4% and 33.3%, for the treatment and non-treatment groups respectively (p = non-significant). Conclusions GnRHa treatment for precocious puberty is not associated with increased risk of polycystic ovary syndrome.

Abstract
BACKGROUND Normative data from pelvic ultrasonography (US) of the pediatric female reproductive organs are outdated and limited by sample size. OBJECTIVE The purpose of this study was to report normal uterine and ovarian volumes and endometrial stripe thickness in children and young adults and throughout the menstrual cycle in post-menarchal adolescents. MATERIALS AND METHODS Females ages 0 through 20 years who underwent pelvic US between January 2010 and May 2014 were identified. After excluding patients with pelvic and/or endocrine pathology, nomograms of uterine and ovarian volumes and endometrial thickness by age year were created. Data for patients ages 12 years and older with a recorded day of last menstrual period were used to create additional nomograms of volumes/thickness throughout the menstrual cycle. Student's t-tests and linear regression were performed to assess differences in measurements between groups and association of volumes/thickness with age. RESULTS During our study period, 5,647 patients underwent 6,953 pelvic US examinations. After further review, 907 examinations from 889 patients were included (mean age: 11.3±6.0 years). Mean pelvic US volumes (cm3) per organ were 25.5±27.0 (uterus), 4.5±4.7 (right ovary) and 4.0±4.1 (left ovary). Mean endometrial thickness was 4.5±3.7 mm. Right ovarian volume was significantly larger than the left (P=0.0126). Uterine volume, ovarian volume and endometrial thickness were significantly associated with age (P-values<0.0001). Plots of mean organ measurements with respect to week of menses are provided. CONCLUSION We report normal volumes of the uterus and ovaries and endometrial stripe thickness measured by pelvic US throughout childhood and adolescence with reference to the menstrual cycle. These values are significantly associated with age and vary visually by menstrual cycle week.

Pelvic Ultrasound in Diagnosing and Evaluating the Efficacy of Gonadotropin-Releasing Hormone Agonist Therapy in Girls With Idiopathic Central Precocious Puberty. Front Pharmacol 2019; 10:104. [PMID: 30804790 PMCID: PMC6378315 DOI: 10.3389/fphar.2019.00104] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2018] [Accepted: 01/25/2019] [Indexed: 11/13/2022] Open
Abstract
Background and Objective: Idiopathic central precocious puberty (ICPP) is characterized by early pubertal changes, the acceleration of growth velocity, and rapid bone maturation that often results in reduced adult height. Gonadotrophin-releasing hormone agonist (GnRHa) is currently considered to be an effective therapeutic agent. At present, GnRH stimulation test is adopted as a gold standard for the diagnosis of ICPP and the efficacy evaluation of GnRHa therapy. However, it is difficult to operate in practice due to the cumbersome procedures and multiple blood samples required. This study was conducted to establish the value of pelvic ultrasound in diagnosing ICPP and evaluating the efficacy of GnRHa therapy. Materials and Methods: One hundred and twenty-two girls with ICPP (ICPP group) were enrolled in the study. Pelvic ultrasound and levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were examined before and after GnRHa therapy for 3 months. Eighty normal prepubertal girls were enrolled as the control group. The difference in pelvic ultrasound parameters between the ICPP group before GnRHa therapy and the control group was compared by independent-sample t-test, while paired t-test for ICPP group before and after GnRHa therapy. Receiver operating characteristic (ROC) curve was used to explore the optimal pelvic ultrasound parameters for diagnosing ICPP. Pearson correlation analysis was performed between the pelvic ultrasound parameters and serum sexual hormone level. Results: The pelvic ultrasound parameters (length of the uterine body, anteroposterior diameter of the uterine body, transverse diameter of the uterine body, volume of the uterine body, uterine body-cervix ratio, length of the ovary, transverse diameter of the ovary, anteroposterior diameter of the ovary, volume of the ovary, number of increased follicles and maximum diameter of the follicle) in the ICPP group before GnRHa therapy were significantly larger than those of the control group (P < 0.05). All the above pelvic ultrasound parameters in the ICPP group were significantly decreased after GnRHa therapy compared with those before treatment (P < 0.05). The volume of the uterine body had the largest area under the ROC curve in differentiating between patients with ICCP and the control group. Pelvic ultrasound parameters were significantly correlated with serum sexual hormone levels (P < 0.05). Conclusion: This study indicates pelvic ultrasound is a simple and reliable tool to diagnose ICPP and evaluates the efficacy of GnRHa therapy by dynamically observing the morphology of internal genitalia. The volume of uterine body was the best ultrasound parameter to distinguish patients with ICPP from normal girls.

Abstract
GnRH analogues (GnRHa) are the treatment of choice for central precocious puberty (CPP), with the main objective to recover the height potential compromised by the premature fusion of growth cartilages. The aim of this review was to analyze long-term effects of GnRHa on height, body weight, reproductive function, and bone mineral density (BMD) in patients with CPP, as well as the potential predictors of outcome. Because randomized controlled trials on the effectiveness and long-term outcomes of treatment are not available, only qualified conclusions about the efficacy of interventions can be drawn. GnRHa treatment appears to improve adult height in girls with CPP, especially if diagnosed before the age of 6, whereas a real benefit in terms of adult height is still controversial in patients with the onset of puberty between 6 and 8 years of age. No height benefit was shown in patients treated after 8 years. Gonadal function is promptly restored in girls after cessation of treatment, and reproductive potential appears normal in young adulthood. Data are conflicting on the long-term risk of polycystic ovarian syndrome in both treated and untreated women. Fat mass is increased at the start of treatment but normalizes thereafter, and GnRHa itself does not seem to have any long-term effect on BMI. Similarly, analogue treatment does not appear to have a negative impact on BMD. Owing to the paucity of data available, no conclusions can be drawn on the repercussions of CPP and/or its treatment on the timing of menopause and on the health of the offspring.

Abstract
Gonadotropin-releasing hormone analogs (GnRHa) are widely used to treat central precocious puberty (CPP). The efficacy and safety of GnRHa treatment are known, but concerns regarding long-term complications are increasing. Follow-up observation results after GnRHa treatment cessation in female CPP patients up to adulthood showed that treatment (especially <6 years) was beneficial for final adult height relative to that of pretreated or untreated patients. Puberty was recovered within 1 year after GnRHa treatment discontinuation, and there were no abnormalities in reproductive function. CPP patients had a relatively high body mass index (BMI) at the time of CPP diagnosis, but BMI standard deviation score maintenance during GnRHa treatment seemed to prevent the aggravation of obesity in many cases. Bone mineral density decreases during GnRHa treatment but recovers to normal afterwards, and peak bone mass formation through bone mineral accretion during puberty is not affected. Recent studies reported a high prevalence of polycystic ovarian syndrome in CPP patients after GnRHa treatment, but it remains unclear whether the cause is the reproductive mechanism of CPP or GnRHa treatment itself. Studies of the psychosocial effects on CPP patients after GnRHa treatment are very limited. Some studies have reported decreases in psychosocial problems after GnRHa treatment. Overall, GnRHa seems effective and safe for CPP patients, based on long-term follow-up studies. There have been only a few long-term studies on GnRHa treatment in CPP patients in Korea; therefore, additional long-term follow-up investigations are needed to establish the efficacy and safety of GnRHa in the Korean population.

Abstract
CONTEXT Central precocious puberty (CPP), treated or untreated, may have implications in adulthood. OBJECTIVE To assess the reproductive outcome and social adjustment of former CPP women between the 3rd and 5th decades of life. DESIGN Cross-sectional study of an historical cohort. METHODS Demographic data and gynaecological history of 214 CPP women aged 25-56 years [135 GnRH analogue (GnRHa)-treated, 18 cyproterone acetate (CyA)-treated, 61 untreated] and of 446 controls with normal puberty, matched for age and year of birth, were recorded in a structured interview. RESULTS Marital status, education and number of children were similar in CPP women and controls. Clinical hyperandrogenism (acne/hirsutism with oligomenorrhoea) was more frequently reported in CPP women than in controls: GnRHa-treated 29·6% vs 17·4% (P = 0·006), CyA-treated 50% vs 20·4% (P = 0·04), untreated 34·4% vs 17·2% (P = 0·003), with no significant difference between CPP groups. Spontaneous pregnancy was similarly achieved by treated CPP and controls: GnRHa-treated 90·4% vs 93·4%, CyA-treated 86·7% vs 90·2%. Assisted fertilization rate was higher in untreated CPP than treated CPP groups (P = 0·006) and controls (P = 0·03). Untreated CPP was the only parameter associated with clinical hyperandrogenism (OR=2·04, 95% CI, 1·0-4·16, P = 0·07) and fertility problems (OR=3·40, 95% CI, 1·15-10·0, P = 0·047). Course of pregnancy was uneventful in 90·2% of CPP women and 90·9% of controls. CONCLUSIONS The increased rate of clinical hyperandrogenism among CPP women implies that the underlying neuroendocrine dysfunction persists into adult life. Pubertal suppression treatment may have a protective effect as fertility problems were more prevalent only among untreated CPP women. Educational achievements and marital status were unaffected by CPP.

Abstract
The measurement of ovarian volume has been shown to be a useful indirect indicator of the ovarian reserve in women of reproductive age, in the diagnosis and management of a number of disorders of puberty and adult reproductive function, and is under investigation as a screening tool for ovarian cancer. To date there is no normative model of ovarian volume throughout life. By searching the published literature for ovarian volume in healthy females, and using our own data from multiple sources (combined n = 59,994) we have generated and robustly validated the first model of ovarian volume from conception to 82 years of age. This model shows that 69% of the variation in ovarian volume is due to age alone. We have shown that in the average case ovarian volume rises from 0.7 mL (95% CI 0.4–1.1 mL) at 2 years of age to a peak of 7.7 mL (95% CI 6.5–9.2 mL) at 20 years of age with a subsequent decline to about 2.8 mL (95% CI 2.7–2.9 mL) at the menopause and smaller volumes thereafter. Our model allows us to generate normal values and ranges for ovarian volume throughout life. This is the first validated normative model of ovarian volume from conception to old age; it will be of use in the diagnosis and management of a number of diverse gynaecological and reproductive conditions in females from birth to menopause and beyond.

Abstract
OBJECTIVE As there are no standard criteria for monitoring suppression during treatment of central precocious puberty (CPP) with gonadotrophin-releasing hormone analogues (GnRHa), we assessed the use of pelvic ultrasound examination for this purpose. DESIGN/PATIENTS/MEASUREMENTS In 31 girls with CPP, transabdominal pelvic ultrasound examination was performed before initiation of therapy with GnRHa, after approximately 3 and 6 months, at last treatment visit and after its discontinuation. RESULTS Three months after treatment initiation, there was a significant decrease in most uterine and ovarian parameters, with at least three parameters decreased in each patient. Endometrial echo was found in 80% of girls before therapy, in 52% (13/25) after 3 months of therapy, in 24% (6/25) after 6 months and in none on the last treatment visit (P < 0·001). In the course of treatment (mean therapy duration 2·5 ± 0·9 years), uterine parameters showed no significant change; ovarian parameters initially showed a decrease and later a modest increase although they were still smaller than before therapy. Within 3-11 months after therapy discontinuation, endometrial echo was detected in 85%, with a significant increase in uterine and ovarian parameters. CONCLUSIONS This prospective study indicates that comparison of individual ultrasound measurements throughout the course of treatment in girls with CPP provides a valid assessment of the suppression of the hypothalamo-pituitary-gonadal axis achieved GnRH therapy. Uterine parameters and absence of endometrial echo were found to be better indicators of adequate suppression than ovarian parameters.

Abstract
OBJECTIVE GNRH analog (GNRHa) therapy has not been supported by beneficial effects on adult stature in girls with early puberty. Furthermore, an increased prevalence of polycystic ovary syndrome (PCOS) has been described in girls treated for central precocious puberty. Women with PCOS are at increased risk of cardiometabolic dysfunctions and infertility. Our aim was to assess GNRHa effectiveness on reaching adult stature and the risk of PCOS in girls with early puberty. DESIGN Longitudinal study of GNRHa-treated and GNRHa-untreated girls at baseline and at final height. METHODS Twenty-five GNRHa-treated girls and 55 controls were compared. Insulin resistance (IR; homeostasis model assessment of IR (HOMA-IR) and glucose-to-insulin ratio (G/I)), the effect of GNRHa on final height, and the prevalence of PCOS were assessed. RESULTS In GNRHa-treated girls, no significant difference was found between predicted final height and final height, whereas a significant difference was detected in untreated girls (P=0.0001). At final height, GNRHa-treated girls showed higher HOMA-IR and lower G/I (P=0.03 for both) as well as higher DHEAS and androstenedione levels (P=0.02 and P=0.01 respectively) than untreated girls. The prevalence of PCOS and hyperandrogenemia was significantly higher in GNRHa-treated adolescents than in untreated adolescents (36 and 14.5% respectively, P=0.04; 56 and 23.6% respectively, P=0.01). Finally, gonadotropin-suppressive therapy was significantly related to PCOS during adolescence (P=0.03). CONCLUSIONS In girls with early puberty, GNRHa therapy is associated with the achievement of predicted final height; nevertheless, this treatment seems to act as an independent risk factor for the development of PCOS already during adolescence.

Clinical, biological and genetic analysis of prepubertal isolated ovarian cyst in 11 girls. PLoS One 2010; 5:e11282. [PMID: 20593028 PMCID: PMC2892512 DOI: 10.1371/journal.pone.0011282] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2010] [Accepted: 05/18/2010] [Indexed: 11/29/2022] Open
Abstract
Background The cause of isolated gonadotropin-independent precocious puberty (PP) with an ovarian cyst is unknown in the majority of cases. Here, we describe 11 new cases of peripheral PP and, based on phenotypes observed in mouse models, we tested the hypothesis that mutations in the GNAS1, NR5A1, LHCGR, FSHR, NR5A1, StAR, DMRT4 and NOBOX may be associated with this phenotype. Methodology/Principal Findings 11 girls with gonadotropin-independent PP were included in this study. Three girls were seen for a history of prenatal ovarian cyst, 6 girls for breast development, and 2 girls for vaginal bleeding. With one exception, all girls were seen before 8 years of age. In 8 cases, an ovarian cyst was detected, and in one case, suspected. One other case has polycystic ovaries, and the remaining case was referred for vaginal bleeding. Four patients had a familial history of ovarian anomalies and/or infertility. Mutations in the coding sequences of the candidate genes GNAS1, NR5A1, LHCGR, FSHR, NR5A1, StAR, DMRT4 and NOBOX were not observed. Conclusions/Significance Ovarian PP shows markedly different clinical features from central PP. Our data suggest that mutations in the GNAS1, NR5A1, LHCGR, FSHR StAR, DMRT4 and NOBOX genes are not responsible for ovarian PP. Further research, including the identification of familial cases, is needed to understand the etiology of ovarian PP.

Abstract
OBJECTIVE Our aim was to evaluate uterine and ovarian ultrasonographic features including endometrial thickness (ET) in adolescent females with PCOS, which is limited in this population. METHODS We performed a retrospective chart review of young females (n=51) ranging in age from 10 to 18 years with the diagnosis of PCOS. Clinical, biochemical and pelvic sonography data were reviewed. Sonographic data included uterine parameters of ET, length, and volume as well as ovarian volume and follicular morphologic features. RESULTS Data in 51 girls were analyzed. Menstrual periods were reported as irregular in 26/51 (50.9%), amenorrheic in 19/51 (37.2%), regular in 4/51 (7.8%) and metrorrhagia in 2/51 (3.9%). Uterine features revealed that the endometrial stripe was enlarged (>7mm) in 16/51 (31.4%) of girls, all with homogeneous appearance. The uterine length was lower than normal in 22/51 (43.1%) of girls, normal in 21/51 (41.2%), and higher than normal in 8/51 (15.7%). Uterine volume was normal in 31/51 (60.7%) and higher in 20/51 (39.3%) of girls. Enlarged ovarian volume was found in 22/51 (43%) of patients. Mean ovarian volumes were 16.1cm(3) and 13.1cm(3) in bilateral and unilaterally enlarged ovaries, respectively. The morphology of ovarian follicles was studied in a subset of 40 patients. The location of ovarian follicles was peripheral in 81% and mixed in 19%. The number of follicles was also examined in 43 patients. They were few (<5) in 12%, moderate (5-10) in 5% and multiple (>10) in 84% cases. There was the presence of at least one >10mm cyst in 25% of girls. CONCLUSION Majority of the adolescents with PCOS demonstrated multiple peripheral ovarian follicles, with large ovarian volumes in some, indicating an important role of ultrasonography in the diagnosis of PCOS, even at a younger age. Endometrial thickness, uterine length, ovarian size, and follicular morphology should be carefully examined in cases of adolescent PCOS.

Abstract
This review describes several aspects of the management of precocious puberty (PP) and variants in girls and boys. PP is characterized by early pubertal changes, acceleration of growth velocity and rapid bone maturation that often result in reduced adult height. Onset of pubertal signs before the age of 8 years in girls and 9 years in boys should always be evaluated carefully. The main principles of therapy are to stop the progression of secondary sex characteristics and menses (in girls), to increase final adult height, to promote psychosocial well-being, and to treat the underlying cause if known.

Abstract
Premature pubarche-defined as the appearance of pubic hair before age 8 years in girls and 9 years in boys-has been traditionally considered a benign entity. However, recent evidence supports the notion that premature pubarche in girls may be a forerunner of the metabolic syndrome, and may precede the development of clinical ovarian androgen excess in adolescence. This sequence seems to occur more frequently when premature pubarche was preceded by reduced fetal growth and followed by excessive postnatal catch-up in height and particularly in weight; hyperinsulinemia appears to be a key factor in the development of this sequence of events. In girls with premature pubarche and a history of a low birth weight, puberty tends to start earlier and to have a faster course, so that final height may be moderately reduced. In these girls, metformin therapy may reverse the progression to clinical ovarian hyperandrogenism, normalize body composition and excess visceral fat, and delay pubertal progression without attenuating linear growth and bone mineralization, suggesting that adult height may be improved. Long-term follow-up of these patients is needed to fully determine the ultimate effects of insulin sensitization as well as the maintenance of these benefits after discontinuation of therapy.

Abstract
As girls with severe cognitive developmental delay progress into puberty and become young women with learning disabilities, concerns about menstruation are common amongst carers and health care professionals are often consulted for advice. Very little, however, has been published on this area to guide the practitioner and studies are almost exclusively confined to the gynaecological literature. We aim to give an account of the various therapeutic options available and current practice within the paediatric endocrinology unit at our institution.

Abstract
Premature adrenarche is characterized by an early increase in adrenal androgen production that results in the development of pubic hair before the age of 8 years in girls and 9 years in boys, with or without axillary hair, and with no other signs of sexual development. Premature adrenarche has no adverse effects on the onset and progression of gonadarche and final height. However, it can no longer be considered a benign condition as it has been associated with hyperinsulinemia, dyslipidemia, and obesity already in the prepubertal period and polycystic ovary syndrome (PCOS) at adolescence. Furthermore, a possible association between premature adrenarche and metabolic and endocrine abnormalities with low birth weight has been postulated. PCOS, as recently redefined, is the most common endocrine disorder to affect women of reproductive age and has been associated with increased risk for type 2 diabetes and increased prevalence of cardiovascular risk factors at an earlier age than expected. Premature adrenarche and PCOS share similar metabolic disturbances. It may be that metabolic abnormalities start very early in life during the prenatal or prepubertal period and premature adrenarche may be a forerunner of PCOS and the metabolic syndrome in some girls. Large long-term epidemiological studies are needed to allow clear association of the two conditions and assessment of the risk of disease in later life.

Abstract
OBJECTIVE To evaluate the adult reproductive outcome in girls with early puberty who participated in a previous random study. STUDY DESIGN A total of 22 subjects treated with triptorelin 3.75 mg every 4 weeks (group 1), 18 subjects not treated (group 2), and 22 age-matched normal volunteers (control group) underwent a physical examination, serum hormone level determination, and pelvic ultrasonography. RESULTS The characteristics of menstrual cycles, serum hormone levels, and ultrasound results did not differ significantly among the 3 groups examined. The mean ovarian volume and the uterine volume tended to increase in the subjects of group 2, but the differences were not significant. The percentage of subjects who reported being sexually active at the time of the examination was greater in the 2 groups with previous early puberty than in the controls (76% of cases in group 1, 72% in group 2, and 59% in the control group). CONCLUSIONS Neither early puberty nor its treatment seems to significantly affect the normal adult function of the pituitary-gonadal axis.

Abstract
The problems of central precocious puberty (CPP) are serious enough to the patient to deserve treatment. There is a general consensus among paediatric endocrinologists that the treatment of true CPP (i.e., in children young enough to have a formal diagnosis) is indicated in many cases. In children with modestly early puberty who are not fulfilling the diagnostic criteria, this is not the case. The treatment of choice is a gonadotropin-releasing hormone (GnRH) analogue. Prolonged analogues are more effective than short-acting ones and, most importantly, independent of patient compliance. Data on agonists have accumulated over two decades and evidence of effects is rich in girls but sparse in boys. GnRH agonists are generally effective and safe drugs; the suppression of puberty is reversible and there is much information on GnRH agonists for the treatment of CPP showing very few adverse effects and the effects on final height are well documented in girls < 6 years of age. There is some (but not highly convincing) evidence for their effect on final height for those of 6 - 8 years of age and there is no evidence for an increase in final height after the age of 8 years in girls. If a decision to have treatment is taken, treatment should start immediately as a possible benefit is less probable if the start of treatment is delayed. When treatment should be stopped is a matter of controversy. Combination with growth hormone increases final height, but the clinical relevance can be discussed as well as the health economy aspects. The limits of indications are still to be defined.

Abstract
OBJECTIVE To evaluate the characteristics of obese girls with gonadotropin releasing hormone-dependent precocious puberty with and without polycystic-like ovaries. METHODS Forty-seven overweight (> 75(th) centile of the Italian reference data) girls with a diagnosis of isosexual precocious puberty underwent auxological analysis, hormonal assay and utero-ovarian sonographic and Doppler evaluation. On the basis of sonography the patients were subdivided into two groups, girls presenting normal ovaries (Group I; n = 31) and those with polycystic-like ovaries (Group II; n = 16). RESULTS The mean body weight was significantly higher (P = 0.003) in Group II than it was in Group I. In addition, the patients with polycystic-like ovaries fell within our definition of superobese (> or = 97(th) centile of the Italian reference data) in 44% of cases. The uterine and ovarian volumes were significantly greater in Group II compared with Group I patients. The Doppler evaluation showed intraparenchymal ovarian vascularization and low downstream impedance to flow in all patients in Group II. CONCLUSIONS Girls with precocious puberty and polycystic ovaries, compared with those without polycystic ovaries, have a higher incidence of body weight exceeding the 85(th) centile of the Italian reference data (obesity).

Abstract
Central precocious puberty (CPP) is characterized by early pubertal changes, acceleration of growth velocity, and rapid bone maturation that often result in reduced adult height. An onset of pubertal signs before the age of 8 years in girls and 9 years in boys should always be evaluated. A combination of clinical signs, bone age, pelvic echography in girls, and hormonal data are required to diagnose CPP and make a judgment concerning progression and prognosis. Not all children with apparently true CPP require medical intervention. The main reasons for treatment are to prevent compromised adult height and to avoid psychosocial or behavioral problems. The need for treatment for auxologic reasons is based on estimation of predicted adult height, with the finding of a reduced height potential, which may require a follow-up. Indication for treatment on the basis of psychologic and behavioral anomalies has to be determined on an individual basis. The main short-term aims of therapy are to stop the progression of secondary sex characteristics and menses (in girls) and to treat the underlying cause, when known. Long-term goals are to increase final adult height and to promote psychosocial well-being. Once it has been decided that treatment is appropriate, it should be initiated immediately with depot gonadotropin-releasing hormone (GnRH) agonists. The effective suppression of pituitary gonadal function is achieved with these compounds in practically all CPP patients. Long-term data are now available from 2 decades of GnRH agonist treatment for patients with CPP. Treatment preserves height potential in the majority of patients (especially in younger patients) and improves the final adult height of children with rapidly progressing CPP, with a complete recovery of the hypothalamic-pituitary-gonadal axis after treatment. GnRH agonist treatment using depot preparations is useful and has a good safety profile, with minimal adverse effects and no severe long-term consequences. Although further data are need, there may be a role in the future for combining somatropin (growth hormone) and GnRH agonist treatment for some patients with significantly impaired growth velocity. The introduction of GnRH antagonists is likely to improve the treatment options for CPP.

Abstract
Hyperandrogenism and chronic anovulation are the most common endocrine disorders of premenopausal women. Most patients have polycystic ovary syndrome (PCOS), which is essentially benign, but might be associated with increased cardiovascular morbidity; PCOS is associated with specific endocrine and ultrasonographic features. Some patients exhibiting similar features to PCOS might have other underlying diagnoses, such as adrenal and ovarian steroidogenic deficiencies, adrenal and ovarian androgen-secreting tumours, other medical or endocrine disorders, and/or be on medications thought to cause PCOS, such as anti-epileptics. Unlike PCOS, some of these conditions can occasionally be life threatening and require prompt diagnosis and treatment. Here, we focus on these disorders, including their pathogenesis, and attempt to define the clinical and biochemical features that distinguish them from PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is a common cause of hyperandrogenism in adolescent girls. In its complete post menarchal expression, the syndrome is characterized by the association of typical clinical, biological, and ultrasonographic findings. Many factors have contributed to our knowledge of different clinical forms of PCOS in adolescent girls. They are helpful for clarifying misleading situations in a period of life when diagnosis of PCOS implies a treatment for many years and may interfere with gynecological outcome. During the last 3 years, we had the opportunity to manage in our unit 45 adolescent girls with ovarian hyperandrogenism: 32 of them had PCOS and the other 13 functional ovarian hyperandrogenism defined by clinical and biological hyperandrogenism without ultrasonographic abnormality. In this review, we report, from our personal experience as well as from recent literature data, the different clinical expressions of PCOS in the pubertal period: the classical post menarchal form, the exceptional pre menarchal form, the post precocious pubarche and the post precocious puberty forms, the familial expression as well as the dominant metabolic expression.

Abstract
Out of 35 girls with idiopathic central precocious puberty (CPP) treated with gonadotropin-releasing hormone agonist (GnRHa) (depot-triptorelin) at a dose of 100 microg/kg every 21 days i.m. for at least 2-3 years whose growth velocity fell below the 25th percentile for chronological age (CA), 17 received growth hormone (GH) in addition at a dose of 0.3 mg/kg/week, s.c., 6 days per week, for 2-4 years. The other 18, matched for bone age (BA), CA and duration of GnRHa treatment, who showed the same growth pattern but refused GH treatment, remained on GnRHa alone, and were used as a control group to evaluate GH efficacy. No patient was GH deficient. Both groups discontinued treatment at a comparable BA (mean +/- SD): BA 13.4 +/- 0.6 in GnRHa plus GH group vs 13.0 +/- 0.5 years in the GnRHa alone group. The 35 patients have reached adult height (i.e. growth during the preceding year was less than 1 cm, with a BA of over 15 years). Patients of the group treated with GH plus GnRHa showed an adult height (161.2 +/- 4.8 cm) significantly higher (p < 0.001) than pre-treatment predicted adult height (PAH) calculated according to tables either for accelerated girls (153.2 +/- 5.0 cm) or for average girls (148.6 +/- 4.3 cm). The adult height of the GnRH alone treated group (156.6 +/- 5.7) was not significantly higher than pre-treatment PAH if calculated on Bayley and Pinneau tables for accelerated girls (153.9 +/- 3.8 cm), whilst it remained significantly higher if calculated on tables for average girls (149.6 +/- 4.0 cm) (p < 0.001). The gain between pre-treatment PAH and final height was 8.2 +/- 4.8 cm according to tables for accelerated girls and 12.7 +/- 4.8 cm according to tables for average girls in patients treated with GH plus GnRHa; while in patients treated with GnRH alone the gain calculated between pre-treatment PAH for accelerated girls was just 2.3 +/- 2.9 cm and 7.1 +/- 2.7 cm greater than pre-treatment PAH for average girls. The difference between the gain obtained in the two groups (about 6 cm) remained the same, however PAH was calculated. The addition of GH to GnRHa in a larger cohort of patients with CPP with a longer follow-up confirms the safety of the combined treatment and the still significant but more variable gain in the group with the combined treatment, probably due to the larger number of patients analyzed. Caution is advised in using such an invasive and expensive treatment, and there is need for further studies before widespread clinical use outside a research setting.

Abstract
OBJECTIVE To evaluate the role of ultrasound and color Doppler analyses in improving the differential diagnosis of pubertal precocities. METHODS Sixty-nine girls with premature (<8 years old) breast development and/or pubic hair growth underwent: auxological (height, weight, body mass index, skeletal maturation), hormonal (basal, gonadotropin releasing hormone (GnRH)-test, adrenocorticotropic hormone test), and sonographic (uterine and ovarian volume and endometrial echo) including color Doppler (uterine arteries) evaluations. RESULTS The uterine size was greater in girls with a pubertal response to the GnRH test (Group II, n = 16; 7.48 +/- 4.18 mL) than in those with a prepubertal response to the GnRH test (Group I, n = 17; 3.02 +/- 1.36 mL; P = 0.006), an isolated pubarche (Group III; n = 20; 2.58 +/- 1.32 mL; P < 0.001) or an isolated thelarche (Group IV, n = 16; 1.82 +/- 1.07 mL; P < 0.001). Endometrial echo was observed in 87.5%, 29.4% and 5% of girls, respectively, in Groups II, I and III. The Doppler analysis of the uterine arteries showed the lowest impedance to be in patients with a pubertal response to the GnRH test (Group II). CONCLUSIONS Sonographic and color Doppler parameters may improve the diagnosis of GnRH-dependent precocious puberty and may be useful to determine which girls need treatment.

Abstract
OBJECTIVE To describe pelvic sonographic findings in girls as old as 7 years, to compare prepubertal girls with girls who had isolated thelarche or central precocious puberty, and to verify the accuracy of sonographic variables for distinguishing prepubertal girls from girls with central precocious puberty. METHODS Ninety-six prepubertal girls and 2 reference groups (8 girls with isolated thelarche and 8 with idiopathic central precocious puberty) were included. Ovaries were classified morphologically as homogeneous, paucicystic, macrocystic, multicystic, and having isolated cysts. Receiver operating characteristic curves were used to choose the best cutoff points. RESULTS Chronologic and bone age were correlated with uterine length, area, and volume and ovarian volume in prepubertal girls (P < .0001). Ovarian morphologic characteristics in prepubertal girls differed significantly from those of the reference groups (P < .0001). The best cutoff points were uterine length of 4.0 cm, uterine area of 4.5 cm2, uterine volume of 3.0 cm3, and ovarian volume of 1.0 cm3. CONCLUSIONS Uterine and ovarian growth are proportional to age in prepubertal girls. Mean ovarian volume greater than 1 cm3 showed 100% sensitivity and specificity for discriminating between prepubertal girls and girls with central precocious puberty. Microcysts are common in prepubertal girls, but the presence of 6 or more follicles up to 10 mm in diameter may suggest central precocious puberty in girls younger than 8 years.

Abstract
BACKGROUND AND OBJECTIVES Depot GnRH analogues are widely used in the treatment of precocious puberty, or suppression of relatively early puberty where growth or psychosocial well-being may be compromised. One example is Zoladex (Z goserelin 3.6 mg), which can be given every 4 weeks. This injection frequency may not always achieve adequate suppression of pubertal signs. A long-acting form, Zoladex-LA 10.8 mg, has now been introduced with a potential duration of action of 12 weeks. In order to assess the efficacy of Zoladex-LA in gonadotrophin suppression we have measured LH and FSH responses to GnRH at diagnosis and 8 and 12 weeks after injection in a group of children treated with Zoladex-LA for central precocious or early puberty. METHODS Forty-nine children (40 girls) with clinical evidence of central precocious puberty (CPP) or early puberty (EP) were started on Zoladex-LA, either de novo (n = 29) or on changing from Zoladex. Ages at diagnosis ranged from 1.7 to 10.6 years (median 7.8 years). Twenty-three had a structural cause with abnormality on magnetic resonance/computerized tomography (MR/CT) head scan, nine had a syndrome or nonspecific brain injury, and in 17 the cause was idiopathic. RESULTS At diagnosis, in the de novo group, median peak LH was 13.6 IU/l and median peak FSH was 12.0 IU/l. By 12 weeks gonadotrophins were suppressed to 0.9 and 0.8 IU/l, respectively. In the previously treated group, median peak LH at diagnosis was 12.8 IU/l and median peak FSH was 15.0 IU/l with suppression to 0.8 and 1.1 IU/l, respectively, at 12 weeks. In the latter group peak FSH was higher than peak LH at both 8 and 12 weeks (P < 0.05) and there was a significant rise in peak LH (P < 0.05) and FSH (P = 0.01) between 8 and 12 weeks. There was no correlation between age at diagnosis and peak LH or FSH at 8 or 12 weeks. Nevertheless, individual patients in both groups showed evidence of incomplete gonadotrophin suppression at 12 weeks. CONCLUSION Zoladex-LA induces a significant reduction in gonadotrophins over 12 weeks. However, there are individuals, particularly those previously on Zoladex, in whom gonadotrophin suppression is waning by 12 weeks. As found with Zoladex, some children with precocious puberty treated with Zoladex-LA may require increased injection frequency, although correlation with clinical evidence of suppression needs to be studied further.

Abstract
OBJECTIVES To evaluate the role of ultrasound and color Doppler analyses in the diagnosis of precocious puberty. METHODS Gray-scale sonographic uterine and ovarian evaluation together with color Doppler analysis of the uterine artery were prospectively performed in 29 girls presenting with premature breast development and pubic hair growth. The values were compared with results obtained from the gonodotrophin releasing hormone stimulation test. Excluded from the study were patients with isolated thelarche or isolated pubarche and those patients with gonodotrophin releasing hormone-independent puberty and with polycystic ovaries. RESULTS According to the Tanner scale, all the girls presented a breast stage of 2-3 and pubic hair stage 2-3. The uterine size was greater in those girls who presented a pubertal response to the gonodotrophin releasing hormone test (Group II; n = 20) (8.07 +/- 4.47 mL) than in those who did not (Group I; n = 9) (3.07 +/- 1.18 mL; P = 0.001). The ovarian volume and the number of small follicles was not significantly different between the groups. On Doppler analysis, more elevated impedances were observed in Group I (pulsatility index = 3.28 +/- 0.37) than in Group II (pulsatility index = 2.29 +/- 0.19; P = 0.001) girls. The presence of a low pulsatility index (< 2.5) at the level of the uterine arteries had a high diagnostic value for precocious puberty (sensitivity 86%, specificity 100%). CONCLUSIONS Uterine artery Doppler analysis may assist the diagnosis of gonodotrophin releasing hormone-dependent precocious puberty, may be useful for the selection of those girls needing treatment, and may simplify the follow-up of girls treated for precocities.

Abstract
This chapter describes several aspects of the management of treatment in girls and boys with central precocious puberty. Although there is some controversy about the indication for gonadotrophin releasing hormone (GnRH) agonist treatment in the literature, a list of clear indications is presented and monitoring requirements for treatment are discussed with reference to the pertinent literature. The development of clinical, psychological, hormonal, sonographical and auxological parameters that can be expected during GnRH agonist treatment is described in detail. In view of the scant evidence-based knowledge, we review the final outcome of patients treated with GnRH agonists with respect to reversibility of hormonal suppression, reproductive function, final height and side effects. The data published so far show that GnRH agonist treatment using the modern depot preparations is not only convenient but also safe, with relatively minor side effects. The outcome in terms of final height is favourable in the majority of patients.

Abstract
Polycystic ovaries and the associated syndrome are recognized as the most common cause of endocrine disturbances in adult women, but much less research has been performed to examine how polycystic ovary syndrome (PCOS) presents in girls and young women. Polycystic ovaries have been demonstrated in childhood, and there is evidence to show that even very young women may show symptoms and signs of the associated syndrome. Closer examination of younger populations (less-than-or-eq, slant 25 years of age), and in particular, studies of girls during the transition from puberty into early adulthood (adolescence), may provide new insights into the pathogenesis and natural history of polycystic ovaries and PCOS, and may indicate whether polycystic ovaries could potentially be considered as a marker for health screening. Consideration should be given to the management of girls and young women with polycystic ovaries and PCOS as this group may have different needs and health risks compared with older women.

Abstract
The aim of this study was to determine serum insulin, insulin-like growth factor-I (IGF-I) and its binding proteins (IGFBP-1 and IGFBP-3) levels and their relationship with androgen levels and ovarian structure in 23 girls with premature pubarche (PP). Fasting levels of testosterone, dehydroepiandrosterone (DHEA) and its sulfate (DHEAS), androstenedione (delta4A), sex hormone binding globulin (SHBG), glucose (G), insulin (I), IGF-I, IGFBP-1, IGFBP-3 were measured. Androgens or steroid hormone levels > 3 SD of normal postpubertal levels were considered as an exaggerated response to the ACTH test. The fasting I to G ratio (FIGR) was calculated and FIGR > 22 was suggestive of insulin resistance (IR). A pelvic ultrasound (US) was carried out and the ovarian structure was divided into five classes (c): c1--homogeneous, c2--microcystic, c3--multicystic, c4--polycystic and c5--follicular. The girls with PP were divided into two groups according to the main ovarian classes observed: PPc1 (n = 6) and PPc2 (n = 15). The FIGR showed IR in 44% of patients. The androgens, SHBG, G, I, FIGR, IGF-I and IGFBP-1 levels were similar among the groups (PPc1 vs PPc2). An exaggerated response to ACTH was more common and IGFBP-3 levels were higher in the PPc2 than in the PPc1 group (p = 0.04). Regression analysis revealed that I was correlated with DHEAS (r = -0.43, p = 0.04) and IGFBP-1 (r = -0.51, p = 0.01); IGF-I was correlated with DHEA (r = -0.42, p = 0.05), delta4A (r = -0.47, p = 0.02), SHBG (r = -0.43, p = 0.04), IGFBP-1 (r = -0.61, p = 0.002) and IGFBP-3 (r = 0.56, p = 0.005); IGFBP-1 was correlated with SHBG (r = 0.56, p = 0.005). These findings suggest that there might be interactions between the insulin-IGF-I-IGFBPs system and hyperandrogenism. However, the possible causal role of adrenal androgen hypersecretion on the insulin-IGF-I-IGFBPs axis and ovarian structure in girls with PP remains to be established. Since studies reveal that IGFBP-3 levels could be a negative predictor for insulin sensitivity throughout puberty, we hypothesize that girls with PP and microcystic ovaries are at risk of developing IR in the course of normal puberty.

Abstract
Adrenarche is the puberty of the adrenal gland. The descriptive term pubarche indicates the appearance of pubic hair, which may be accompanied by axillary hair. This process is considered premature if it occurs before age 8 yr in girls and 9 yr in boys. The chief hormonal product of adrenarche is dehydroepiandrosterone (DHEA) and its sulfated product DHEA-S. The well documented evolution of adrenarche in primates and man is incompatible with either a neutral or harmful role for DHEA and implies most likely a positive role for some aspect of young adult pubertal maturation and developmental maturation. Premature adrenarche has no adverse effects on the onset and progression of gonadarche in final height. Both extra- and intraadrenal factors regulate adrenal androgen secretion. Recent studies have shown that premature adrenarche in childhood may have consequences such as functional ovarian hyperandrogenism, polycystic ovarian syndrome, and insulin resistance in later life, sometimes already recognizable in childhood or adolescence. Premature adrenarche may thus be a forerunner of syndrome X in some children. The association of these endocrine-metabolic abnormalities with reduced fetal growth and their genetic basis remain to be elucidated.

Abstract
GnRH analogues (GnRHa) arrest pubertal development, and slow growth velocity (GV) and bone maturation, thus improving adult height in central precocious puberty (CPP). In some patients, however, GV decreases to such an extent that it compromises the improvement in predicted adult height (PAH) and therefore the addition of GH is suggested. Of 20 patients with idiopathic CPP (treated with GnRHa [depot-triptorelin] at a dose of 100 microg/kg every 21 days i.m. for at least 2-3 yr) whose GV fell below the 25th percentile for chronological age (CA), ten received, in addition to the GnRHa, GH at a dose of 0.3 mg/kg/wk, s.c. 6 days weekly, for 2-4 yr. Ten patients matched for BA, CA, and duration of GnRHa treatment who showed the same growth pattern but refused GH treatment, served to evaluate the efficacy of the addition of GH. No patient showed classical GH deficiency. Both groups discontinued treatment at a comparable BA (mean +/- SEM): 13.2 +/- 0.2 yr in GnRHa + GH vs 13.0 +/- 0.1 yr in the control group. At the conclusion of the study all the patients had achieved adult height. Adult height was considered to be attained when the growth during the preceding year was less than 1 cm, with a BA of over 15 yr. Patients of the group treated with GH + GnRHa showed an adult height significantly higher (p<0.001) than pretreatment PAH (160.6 +/- 1.3 vs 152.7 +/- 1.7 cm). Height SDS for BA significantly increased from -1.5 +/- 0.2 at start of GnRHa to -0.21 +/- 0.2 at adult height (p<0.001). Target height was significantly exceeded. The GnRH alone treated group reached an adult height not significantly higher than pretreatment PAH (157.1 +/- 2.5 vs 155.5 +/- 1.9 cm). Height SDS for BA did not change (from -1.0 +/- 0.3 at start of GnRHa to -0.7 +/- 0.4 at adult height). Target height was just reached but not significantly exceeded. The gain in centimeters obtained calculated between pretreatment PAH and final height was 7.9 +/- 1.1 cm in patients treated with GH combined with GnRH analogue while in patients treated with GnRH analogue alone the gain was just 1.6 cm +/- 1.2 (p=0.001). Furthermore, no side effects, bone age progression, or ovarian cysts, were observed in GnRHa + GH treated patients. In conclusion, a gain of 7.9 cm in adult height represents a significant improvement which justifies the addition of GH for 2-3 yr to conventional treatment with GnRH analogues in patients with central precocious puberty, and with a decrease in growth velocity so marked as to impair predicted adult height to below the third percentile.

Abstract
GnRH analogues (GnRHa) represent the treatment of choice in central precocious puberty (CPP), because arresting pubertal development and reducing either growth velocity (GV) or bone maturation (BA) should improve adult height. However, in some patients, GV decrease is so remarkable that it impairs predicted adult height (PAH); and therefore, the addition of GH is suggested. Out of twenty subjects with idiopathic CPP (treated with GnRHa depot-triptorelin, at a dose of 100 microg/kg im every 21 days, for at least 2-3 yr), whose GV fall below the 25th percentile for chronological age, 10 received, in addition to GnRHa, GH at a dose of 0.3 mg/kg x week s.c., 6 days weekly, for 2-4 yr; and 10 matched for BA, chronological age, and duration of GnRHa treatment, who showed the same growth pattern but refused GH treatment, served to evaluate the efficacy of GH addition. No patient showed classical GH deficiency. Both groups discontinued treatment at a comparable BA (mean +/- SEM): 13.2 +/- 0.2 in GnRHa plus GH vs. 13.0 +/- 0.1 yr in the control group. At the conclusion of the study, all the patients had achieved adult height. Adult height was considered to be attained when the growth during the preceding year was less than 1 cm, with a BA of over 15 yr. Patients of the group treated with GH plus GnRHa showed an adult height significantly higher (P < 0.001) than pretreatment PAH (160.6 +/- 1.3 vs. 152.7 +/- 1.7 cm). Target height (TH) was significantly exceeded. The group treated with GnRH alone reached an adult height not significantly higher than pretreatment PAH (157.1 +/- 2.5 vs. 155.5 +/- 1.9 cm). TH was just reached but not significantly exceeded. The gain in centimeters obtained, calculated between pretreatment PAH and final height, was 7.9 +/- 1.1 cm in patients treated with GH combined with GnRHa; whereas in patients treated with GnRHa alone, the gain was just 1.6 +/- 1.2 cm (P = 0.001). Furthermore, no side effects have been observed either on bone age progression or ovarian cyst appearance and the gynecological follow-up in the GH-treated patients (in comparison with those treated with GnRHa alone). In conclusion, a gain of 7.9 cm in adult height represents a significant improvement, which justifies the addition of GH for 2-3 yr during the conventional treatment with GnRHa, especially in patients with CPP, and a decrease in GV so marked as to impair PAH, not allowing it to reach even the third centile.

Abstract
Although the GnRH agonist analogs have become an established treatment for precocious puberty, there have been few long term studies of reproductive function and general health after discontinuation of therapy. To this end, we compared peak LH and FSH after 100 microg sc GnRH, estradiol, mean ovarian volume (MOV), age of onset and frequency of menses, body mass (BMI), and incidence of neurological and psychiatric problems in 2 groups of girls: those with precocious puberty due to hypothalamic hamartoma (HH; n 18) and those with idiopathic precocious puberty (IPP; n = 32) who had been treated with deslorelin (4-8 microg/kg x day, s.c.) or histrelin (10 microg/kg x day, s.c.) for 3.1-10.3 yr and were observed at 1, 2, 3, and 4-5 yr after discontinuation of treatment. The endocrine findings were also compared to those in 14 normal perimenarcheal girls. There were no differences between the HH and IPP groups in age or bone age at the start of treatment, at the end of treatment, or during GnRH analog therapy. We found that whereas the peak LH level was higher in HH than in IPP girls before (165.5 +/- 129 vs. 97.5 +/- 55.7; P < 0.02) and at the end (6.8 +/- 6.0 vs. 3.9 +/- 1.8 mIU/mL; P < 0.05) of therapy, this difference did not persist at any of the posttherapy time points. LH, FSH, and estradiol rose into the pubertal range by 1 yr posttherapy in both HH and IPP. However, the mean posttherapy peak LH levels in both HH and IPP groups tended to be lower than normal, whereas the peak FSH levels were not different from normal, so that the overall posttherapy LH/FSH ratio was decreased compared to that in the normal girls (HH, 2.7 +/- 0.3; IPP, 2.6 +/- 0.1; normal, 5.2 +/- 4.8; P < 0.05). The MOV was larger in HH than IPP at the end of treatment (3.7 +/- 3.5 vs. 2.0 +/- 1.2 mL; P < 0.05) and tended to increase in both groups over time to become larger than that in normal girls by 4-5 yr posttherapy (HH, 14.9 +/- 12.9; IPP, 7.6 +/- 2.2; normal, 5.4 +/- 2.5 mL; P < 0.05). Whereas the onset of spontaneous menses varied widely in both groups, once menses had started, the HH group had a higher incidence of oligomenorrhea. Pelvic ultrasonography revealed more than 10-mm hypoechoic regions in 4 HH patients, 15 IPP patients, and 3 normal girls, all of whom were reporting regular menses. Live births of normal infants were reported by 2 HH and 2 IPP patients, and elective terminations of pregnancy were reported by 1 HH and 2 IPP patients. BMI was greater than normal in HH and IPP both before treatment and at all posttherapy time points and tended to be higher in the HH patients. Marked obesity (BMI, +2 to +5.2 SD score) was observed in 5 HH and 6 IPP patients, 1 of whom had a BMI of +2.5 SD score and developed acanthosis nigricans, insulin resistance, and hyperglycemia. Seizure disorders developed during GnRH analog therapy in 5 HH and 1 IPP patient, and 2 additional HH girls developed severe depression and emotional lability posttherapy. Although the mean anterior-posterior dimension of the hamartoma was larger in the HH patients with seizure than in those who were seizure free (1.7 +/- 1.2 vs. 0.9 +/- 0.4 cm; P < 0.05), no change in hamartoma size was observed either during or after therapy, and no patient has reported the onset of a seizure disorder posttherapy. Other than a tendency toward a larger MOV, a higher incidence of oligomenorrhea, obesity, and frequency of neurological disorders, recovery of the reproductive axis after GnRH analog therapy was not markedly different in HH compared to IPP. Continued follow-up of these patients may determine whether the decreased LH responses and increased BMI in both groups compared to those in normal girls remain clinically significant problems.

Abstract
Adolescent girls with a history of premature pubarche have an increased incidence of functional ovarian hyperandrogenism [a form of polycystic ovary syndrome (PCOS)] at adolescence, which is usually associated with hyperinsulinemia and dyslipemia. The hyperinsulinemia and lipid disturbances can often be detected in the prepubertal period and throughout puberty, and are associated with an exaggerated ovarian androgen synthesis. Birthweight SD scores are lower in premature pubarche girls than in control girls, and particularly so in those girls who show hyperinsulinemia and subsequently develop ovarian hyperandrogenism. Therefore, although the mechanisms interlinking the triad of premature pubarche, hyperinsulinism and ovarian hyperandrogenism remain enigmatic, these data indicate that the triad may result, at least in part, from a common early origin, rather than from a direct interrelationship later in life.

Abstract
The polycystic ovary syndrome has a pubertal onset, with menstrual cycle irregularities and infertility in adulthood, as well as general health hazards such as increased risk for diabetes mellitus and myocardial infarction. Thus, prevention would be important. But as specific etiological factors are not known, nor is specific intervention. In order to use long-term intervention programs in children and adolescents, particularly rigid criteria must be used regarding proven safety and efficacy. In obese subjects, weight loss is very important, having beneficial effects on most aspects of the syndrome, such as subjective symptoms, infertility, hyperinsulinemia and related metabolic aberrations, and long-term health risks. Well controlled, long-term follow-up studies are needed on the role of prepubertal hyperandrogenism, hyperinsulinemia, gonadotropins, and ovarian morphological aspects in the development of PCOS, and possibilities of prevention.

Abstract
Pelvic ultrasonography was systematically performed on 33 girls with idiopathic central precocious puberty to investigate the impact of treatment with gonadotropin-releasing hormone analogues on female internal genitalia. All girls were treated with a long-acting gonadotropin-releasing hormone analogue (Decapeptyl Depot; Ferring Co., Copenhagen, Denmark) 75 micrograms/kg every 4 weeks. Before, during, and after treatment, pelvic ultrasonography was performed and ovarian and uterine volumes were calculated. The size of follicles > 5 mm were accurately measured. The results were related to a normative study of healthy Danish schoolgirls. Our data demonstrated that ovaries and uterus are enlarged in a significant number of girls (50%) with the diagnosis of central precocious puberty at the time of diagnosis. Median ovarian volume at time of diagnosis was 1.1 standard deviation scores (range -0.6 to 3.2 SD), median uterine volume was 1.8 standard deviation scores (range 0.0 to 3.5 SD). Within 3 months of treatment, both ovarian and uterine volumes decreased significantly (p < 0.01) to normal values appropriate for age. Median ovarian volume after 3 months of treatment was 0.0 SD (range -2.4 to 1.5 SD); median uterine volume was 0.7 SD (range -0.6 to 4.1 SD). Ovarian and uterine volume remained within normal range (< 2 standard deviation scores) after discontinuation of treatment. Follicles and macrocysts regressed during treatment. None of the girls' ovaries had a polycystic appearance during or after treatment with the gonadotropin-releasing hormone analogue. Our results confirmed pelvic ultrasonography as a reliable tool for investigation of internal genitalia in girls with precocious puberty and as a valid method for evaluation of the efficacy of treatment with gonadotropin-releasing hormone analogues. We suggest that repeated investigations be performed when evaluating treatment because the morphologic changes, including follicular maturation or regression, reflect ovarian stimulation or suppression. We found no evidence that girls with precocious puberty treated with long-acting gonadotropin-releasing hormone analogues have enlarged polycystic ovaries develop.
