[PMID: 38969860 DOI: 10.1007/s00247-024-05986-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2024] [Revised: 06/21/2024] [Accepted: 06/25/2024] [Indexed: 07/07/2024]
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.

Pediatr Radiol 2024:10.1007/s00247-024-05992-8. [PMID: 39069591 DOI: 10.1007/s00247-024-05992-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2024] [Revised: 06/26/2024] [Accepted: 06/28/2024] [Indexed: 07/30/2024]
Abstract
Precocious puberty in girls is defined by the appearance of secondary sex characteristics before the age of 8 years. Precocious puberty is either peripheral or central. In most cases, the cause of central precocious puberty is unknown. Rapidly progressive forms of central precocious puberty may benefit from puberty suppression to prevent compromised final height and psychosocial problems related to the physical changes. Idiopathic central precocious puberty in girls can be a challenging diagnosis. Clinical examination, evaluation of growth charts, bone age, and hormonal tests are part of the workup. The role of pelvic ultrasound to evaluate pubertal features of the internal genitalia in this context is controversial. In this paper, we have reviewed the literature to find the scientific bases for several proposed ultrasound parameters and cutoff values for the determination of onset of puberty in girls with suspected central precocious puberty. There are no reliable cutoffs for the measurements of uterus and ovaries for the diagnosis of central precocious puberty and there is overlap in the appearance of the organs in both prepubertal and pubertal girls. The interpretation of the findings on pelvic ultrasound must be done with caution and always in close communication with the referring clinicians.

Abstract
Introduction Sonography is a non-invasive and painless technique used for assessing pelvic anatomy and disorder in children and adolescents. Ovarian growth patterns during infancy and puberty are not completely understood. No consensus exists about the normal measures and morphologic appearance of the ovaries in the southern region of Saudi Arabia. Therefore, this study determined the pattern of ovarian and uterine sizes among Saudi girls and their correlation with age. Methods This study was conducted in the radiology department at Abha Maternity and Children Hospital among girls between 0-13 years. All the participants underwent transabdominal ultrasound, and we measured ovarian volume, uterine length, and endometrial thickness to correlate with chronologic age using the Chi-squared test. Results A Total of 152 females were included in this study. The median age was 72 months, with a minimum of one month and a maximum of 156 months. The Chi-squared test showed a significant correlation between age and ovarian measurement. Age was positively associated with ovarian volume, uterine length, and endometrial thickness (p<0.001). Conclusion The study concluded that age strongly correlated with the size of the uterus and ovaries, which is crucial in interpreting ultrasound measurements of the pelvic organs correctly.

Abstract
STUDY OBJECTIVE To identify preoperative transabdominal sonographic predictors of surgically-confirmed ovarian torsion (OT) in premenarchal girls. METHODS Retrospective case-control study of 32 premenarchal girls aged 0-12 undergoing surgery for OT (cases) or a non-torsed ovarian mass (controls) from 2006-2017 at a single academic center. Cases had ICD-9/10 codes for torsion of the ovary, adnexa, ovarian pedicle, or fallopian tube and surgically-confirmed OT; controls had codes for ovarian mass or cyst and surgically-confirmed absence of OT. Preoperative transabdominal ultrasounds were analyzed by three radiologists blinded to final diagnosis. Chi-square, Fisher's exact, and Student's t-test were used for statistical comparisons. RESULTS From 2016-2017, 32 patients presented with acute abdominal pain or symptoms concerning for ovarian mass requiring ultrasound imaging and subsequent diagnostic laparoscopy-24 (75.0%) had confirmed OT by laparoscopy; eight (25.0%) did not. Mean age in both groups was similar (7.3±2.9 years). Preoperative sonographic variables significantly associated with OT included presence of a simple cyst (20.8% vs 12.5%), ovarian heterogeneity (100% vs 12.5%), presence of peripheralized follicles (70.8% vs 0%), and asymmetry of color Doppler (75.0% vs 37.5%)-all p<0.05. Presence of free fluid, arterial color Doppler, and a whirlpool sign were not predictive of OT. CONCLUSION In premenarchal patients, while certain variables on transabdominal sonography predicted surgically-confirmed OT, only the presence of peripheralized follicles was unique to girls with OT. The decision to proceed with diagnostic laparoscopy for suspected OT can be aided by these specific sonographic findings but should ultimately be based on high clinical suspicion.

Abstract
PURPOSE There is a lack of uniformity in the definition of normal ovary ultrasound parameters. Our aim was to summarize and meta-analyze the evidence on the topic. Full-text English articles published through December 31, 2020 were retrieved via MEDLINE and Embase. Data available for meta-analysis included: ovarian follicular count, ovarian volume, and ovarian Pulsatility Index (PI) assessed by Doppler ultrasound. METHODS Cohort, cross-sectional, prospective studies with a single or double arm were considered eligible. Interventional studies were included when providing baseline data. Both studies on pre- and post-menopausal women were screened; however, data on menopausal women were not sufficient to perform a meta-analysis. Studies on pre-pubertal girls were considered separately. Eighty-one papers were included in the meta-analysis. RESULTS The mean ovarian volume was 6.11 [5.81-6.42] ml in healthy women in reproductive age (5.81-6.42) and 1.67 ml [1.02-2.32] in pre-pubertal girls. In reproductive age, the mean follicular count was 8.04 [7.26-8.82] when calculated in the whole ovary and 5.88 [5.20-6.56] in an ovarian section, and the mean ovarian PI was 1.86 [1.35-2.37]. Age and the frequency of the transducers partly modulated these values. In particular, the 25-30-year group showed the higher mean follicular count (9.27 [7.71-10.82]), followed by a progressive age-related reduction (5.67 [2.23-9.12] in fertile women > 35 years). A significant difference in follicular count was also found according to the transducer's upper MHz limit. CONCLUSION Our findings provide a significant input to improve the interpretation and diagnostic accuracy of ovarian ultrasound parameters in different physiological and pathological settings.

Abstract
Polycystic ovary syndrome (PCOS) is a common, complex, and chronic condition that presents many diagnostic and management challenges for managing clinicians. PCOS diagnosis in adolescents presents a particular challenge for treating clinicians due to the overlap of diagnostic features with normal physiological changes during adolescence. Adolescent diagnostic criteria include well-defined menstrual irregularity according to time postmenarche and hyperandrogenism, but does not require the use of pelvic ultrasound. Adolescents with only one criterion should be considered at risk of PCOS and be followed up around transition to adult care. While PCOS was traditionally considered to be a reproductive disorder, PCOS is now recognized to have major metabolic and cardiovascular health consequences and psychological sequelae that can be present from adolescence. Management of PCOS includes healthy lifestyle, metformin, combined oral contraceptive pill, and/or antiandrogens according to symptoms of concern even in adolescents at risk of PCOS.

Abstract
Background Pelvic ultrasonography (PUS) of the uterus and ovaries allows the diagnosis of changes in sexual development. However, the reference values used in Spain originate from old studies conducted in other countries. Objective To determine reference uterine and ovarian measurements by PUS and according to pubertal status and bone age in a Spanish population of healthy girls aged between 6 and 12 years. Materials and methods Descriptive cross-sectional study performed on 221 healthy girls from 2017 to 2019. Ovarian and uterine measurements were described and associated with chronological age, bone age, and Tanner stage. ROC curves were used to assess the predictive value of tests for Tanner stage II. Results We described reference values for all PUS uterine and ovarian measurements assessed. Subjects in Tanner II (thelarche) had a mean age of 9.7 years (SD = 1.1) and mean BMI of 19.2 kg/m2. Fundal-cervical ratio changed from 1:1 to 2:1 at 12 years of chronological age (62.5% with 1:1 ratio; p < 0.0001) and 13 years of bone age (2:1 in 85.71%, p < 0.0001). Mean uterine length for Tanner II was 4.065 cm (SD = 0.736); mean ovarian volume was 2.466 cm3 (SD = 1.719). Bone age, ovarian volume, and uterine length were good predictors of Tanner stage II. Conclusion This is the first study providing reference uterine and ovarian PUS values in a Spanish population of healthy girls aged 6 to 12 years. Use of updated data characteristic of a specific population increases the diagnostic accuracy.

Abstract
BACKGROUND The gonadotropin-releasing hormone (GnRH) stimulation test is the benchmark for diagnosing precocious puberty (PP). However, it is invasive, time-consuming, costly, and may create an unpleasant experience for participants. Moreover, some overlaps may occur between PP and premature thelarche (PT) in the early stage of PP. Female pelvic ultrasonography may provide additional information to help differentiate PP from PT and subsequently initiate early treatment. In this study, we aimed to first directly compare pelvic ultrasonography parameters between PP and PT groups and secondly, investigate their diagnostic accuracy compared with the GnRH stimulation test. METHODS A systematic search of the PubMed/MEDLINE, EMBASE, Scopus, and Cochrane Library databases was performed up to March 31, 2021. All types of studies, except for case reports and review articles, were included. The GnRH stimulation test was used to confirm PP diagnosis. Those whose organic conditions might cause PP were excluded. The mean, standard deviation, sensitivity, and specificity of each parameter were documented. Forest plots were constructed to display the estimated standardized mean differences (SMDs) from each included study and the overall calculations. A bivariate model was used to calculate the pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR). RESULTS A total of 13 studies were included for analysis. The SMDs (95% confidence interval - CI) in ovarian volume, fundal-cervical ratio, uterine length, uterine cross-sectional area, and uterine volume between PP and PT groups were 1.12 (0.78-1.45; p < 0.01), 0.90 (0.07-1.73; p = 0.03), 1.38 (0.99-1.78; p < 0.01), 1.06 (0.61-1.50; p < 0.01), and 1.21 (0.84-1.58; p <0.01), respectively. A uterine length of 3.20 cm yielded a pooled sensitivity of 81.8% (95% CI 78.3%-84.9%), specificity of 82.0% (95% CI 61.0%-93.0%), PLR of 4.56 (95% CI 2.15-9.69), NLR of 0.26 (95% CI 0.17-0.39), and DOR of 19.62 (95% CI 6.45-59.68). The area under the summary receiver operating characteristics curve was 0.82. CONCLUSION Female pelvic ultrasonography may serve as a complementary tool to the GnRH stimulation test in differentiating PP from PT.

Abstract
There is emerging evidence that early uterine development in humans is an important determinant of conditions such as ontogenetic progesterone resistance, menstrual preconditioning, defective deep placentation and pre-eclampsia in young adolescents. A key observation is the relative infrequency of neonatal uterine bleeding and hormone withdrawal at birth. The origin of the uterus from the fusion of the two paramesonephric, or Müllerian, ducts was described almost 200 years ago. The uterus forms around the 10th week of foetal life. The uterine corpus and the cervix react differently to the circulating steroid hormones during pregnancy. Adult uterine proportions are not attained until after puberty. It is unclear if the endometrial microbiome and immune response-which are areas of growing interest in the adult-play a role in the early stages of uterine development. The aim is to review the phases of uterine development up until the onset of puberty in order to trace the origin of abnormal development and to assess current knowledge for features that may be linked to conditions encountered later in life. The narrative review incorporates literature searches of Medline, PubMed and Scopus using the broad terms individually and then in combination: uterus, development, anatomy, microscopy, embryology, foetus, (pre)-puberty, menarche, microbiome and immune cells. Identified articles were assessed manually for relevance, any linked articles and historical textbooks. We included some animal studies of molecular mechanisms. There are competing theories about the contributions of the Müllerian and Wolffian ducts to the developing uterus. Endometrium features are suggestive of an oestrogen effect at 16-20 weeks gestation. The discrepancy in the reported expression of oestrogen receptor is likely to be related to the higher sensitivity of more recent techniques. Primitive endometrial glands appear around 20 weeks. Features of progestogen action are expressed late in the third trimester. Interestingly, progesterone receptor expression is higher at mid-gestation than at birth when features of endometrial maturation are rare. Neonatal uterine bleeding occurs in around 5% of neonates. Myometrial differentiation progresses from the mesenchyme surrounding the endometrium at the level of the cervix. During infancy, the uterus and endometrium remain inactive. The beginning of uterine growth precedes the onset of puberty and continues for several years after menarche. Uterine anomalies may result from fusion defects or atresia of one or both Müllerian ducts. Organogenetic differentiation of Müllerian epithelium to form the endometrial and endocervical epithelium may be independent of circulating steroids. A number of genes have been identified that are involved in endometrial and myometrial differentiation although gene mutations have not been demonstrated to be common in cases of uterine malformation. The role, if any, of the microbiome in relation to uterine development remains speculative. Modern molecular techniques applied to rodent models have enhanced our understanding of uterine molecular mechanisms and their interactions. However, little is known about functional correlates or features with relevance to adult onset of uterine disease in humans. Prepubertal growth and development lends itself to non-invasive diagnostics such as ultrasound and MRI. Increased awareness of the occurrence of neonatal uterine bleeding and of the potential impact on adult onset disease may stimulate renewed research in this area.

Abstract
A 9-year-old girl attended the emergency department with right-sided abdominal pain and vomiting. Due to history and following examination, an ultrasound was requested which demonstrated a large complex midline mass. The most likely diagnosis was ovarian torsion, for which the patient underwent laparoscopy, detorsion and ovarian cystectomy. Histology revealed a mature cystic teratoma. Although less common than in the adult population, it is important to consider ovarian torsion in children and adolescents. Presentation is usually with pain accompanied by vomiting and fever, although these symptoms are not always present. Current management is organ-sparing, with laparoscopy±cystectomy. We discuss the adaptations for this procedure with regard to the paediatric and adolescent population. Differences in the anatomy and physiology must lead to consideration for alterations in surgical technique and positioning to ensure the safest and best quality care for these young patients.

BMC Med 2020; 18:72. [PMID: 32204714 PMCID: PMC7092491 DOI: 10.1186/s12916-020-01516-x] [Citation(s) in RCA: 87] [Impact Index Per Article: 21.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Accepted: 02/11/2020] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Diagnosing polycystic ovary syndrome (PCOS) during adolescence is challenging because features of normal pubertal development overlap with adult diagnostic criteria. The international evidence-based PCOS Guideline aimed to promote accurate and timely diagnosis, to optimise consistent care, and to improve health outcomes for adolescents and women with PCOS. METHODS International healthcare professionals, evidence synthesis teams and consumers informed the priorities, reviewed published data and synthesised the recommendations for the Guideline. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework was applied to appraise the evidence quality and the feasibility, acceptability, cost, implementation and strength of the recommendations. RESULTS This paper focuses on the specific adolescent PCOS Guideline recommendations. Specific criteria to improve diagnostic accuracy and avoid over diagnosis include: (1) irregular menstrual cycles defined according to years post-menarche; > 90 days for any one cycle (> 1 year post-menarche), cycles< 21 or > 45 days (> 1 to < 3 years post-menarche); cycles < 21 or > 35 days (> 3 years post-menarche) and primary amenorrhea by age 15 or > 3 years post-thelarche. Irregular menstrual cycles (< 1 year post-menarche) represent normal pubertal transition. (2) Hyperandrogenism defined as hirsutism, severe acne and/or biochemical hyperandrogenaemia confirmed using validated high-quality assays. (3) Pelvic ultrasound not recommended for diagnosis of PCOS within 8 years post menarche. (4) Anti-Müllerian hormone levels not recommended for PCOS diagnosis; and (5) exclusion of other disorders that mimic PCOS. For adolescents who have features of PCOS but do not meet diagnostic criteria an 'at risk' label can be considered with appropriate symptomatic treatment and regular re-evaluations. Menstrual cycle re-evaluation can occur over 3 years post menarche and where only menstrual irregularity or hyperandrogenism are present initially, evaluation with ultrasound can occur after 8 years post menarche. Screening for anxiety and depression is required and assessment of eating disorders warrants consideration. Available data endorse the benefits of healthy lifestyle interventions to prevent excess weight gain and should be recommended. For symptom management, the combined oral contraceptive pill and/or metformin may be beneficial. CONCLUSIONS Extensive international engagement accompanied by rigorous processes honed both diagnostic criteria and treatment recommendations for PCOS during adolescence.

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.

Abstract
BACKGROUND Changes that occur in the remaining ovary after contralateral oophorectomy are not well described. OBJECTIVE To determine average ovarian volume in pediatric patients after contralateral oophorectomy compared to age-matched controls with two normal ovaries. MATERIALS AND METHODS We performed a retrospective review of ultrasound examinations and electronic medical records of patients ages 0-18 years who had unilateral oophorectomy from 2000 to 2017 (n=64). We used 384 consecutive normal age-matched ovaries for comparison, analyzing mean ovarian volumes. RESULTS Higher mean ovarian volume (mL) was observed in patients who had oophorectomy compared to controls in the first decade of life (P<0.003) and second decade of life (P<0.0003). Higher mean ovarian volume was seen in both premenarchal and menstruating patients with prior oophorectomy when compared to controls (P<0.05 and P<0.0001, respectively). When comparing volume during menstrual cycle, we saw higher mean ovarian volumes in the oophorectomy group compared to the control group for the follicular (P<0.0001), pre-ovulatory (P=0.0005) and luteal phases (P<0.0003). We provide an updated reference of normal ovarian volumes for pediatric patients, with values similar to those already reported in the literature. CONCLUSION Ovarian volume is higher in pediatric patients with one normal ovary following contralateral oophorectomy. The provided normative volumes can be used in evaluating these patients.

Abstract
BACKGROUND Ionizing radiation is known to be capable of causing cancer of many organs, but its relationship with uterine cancer has not been well characterized. METHODS We studied incidence of uterine cancer during 1958-2009 among 62 534 female atomic bomb survivors. Using Poisson regression analysis, we fitted excess relative risk (ERR) models to uterine cancer rates adjusted for several lifestyle and reproductive factors. Person-years at risk were also adjusted for the probability of prior hysterectomy, because it could affect the subsequent risk of uterine cancer. We assessed the modifying effect of age and other factors on the radiation risk. For analysis of the modifying effect of age at radiation exposure around menarche, we compared the radiation risk for several exposure-age categories as well as using parametric models. RESULTS There were 224 uterine corpus cancers and 982 cervical cancers. We found a significant association between radiation dose and risk of corpus cancer (ERR per Gray [ERR/Gy] = 0.73, 95% confidence interval [CI] = 0.03 to 1.87) but not for cervical cancer (ERR/Gy = 0.00, 95% CI = -0.22 to 0.31). For corpus cancer, we found statistically significant heterogeneity in ERR/Gy by age (P heterogeneity = .001) with elevated risk for women exposed to radiation between ages 11 and 15 years (ERR/Gy = 4.10, 95% CI = 1.47 to 8.42) and no indication of a radiation effect for exposures before or after this exposure-age range. CONCLUSIONS The current data suggest that uterine corpus is especially sensitive to the carcinogenic effect of radiation exposure occurring during the mid-pubertal period preceding menarche. There is little evidence for a radiation effect on cervical cancer risk.

Abstract
Gynecologic examination of the pediatric adolescent patient provides a valuable opportunity for patient education and diagnosis, yet presents special challenges, including achieving comfort for the patient and guardian and finding equipment that are sized for pediatric patient. Anatomic changes due to the hormonal environment evolve from newborn through pubertal development. As pediatric adolescent gynecology has evolved as a specialty, techniques and training for providing optimal office and surgical examination have emerged. Where possible, the patient should be engaged with the examination through use of a mirror or positioning. Smaller swabs should be used for testing for vaginal infection in prepubertal patients. When speculum or office examination is not possible, use of narrow-caliber, flexible, and rigid hysteroscopes allow vaginoscopy for assessment.

Abstract
Gynecologists are often consulted on pediatric and adolescent patients who may require a surgical treatment for a gynecologic diagnosis. This patient population can present an interesting challenge for a nonpediatrician. It is helpful to review the differences in anatomy, alterations in drug dosing, surgical limitations, and counseling and consent requirements in this patient population before proceeding with a surgical treatment. This is a review of preoperative, intraoperative, and postoperative considerations for gynecologic surgery in the pediatric and adolescent patient population.

Abstract
Cetaceans exhibit vaginal folds, unusual protrusions of the vaginal wall into the vaginal lumen. Inconsistent terminology and a lack of anatomical landmarks in the literature have hindered comparative studies of the form and function of vaginal folds. Our objectives are to: (1) develop a standardized measurement protocol for the reproductive tracts of female cetaceans, (2) assess variation in morphometrics within the common bottlenose dolphin (Tursiops truncatus), and (3) determine if vaginal muscle is skeletal, and therefore of somatic origin in this species. We selected 15 measurements to characterize female reproductive tracts and evaluated variability using fresh or frozen-thawed specimens from southeastern USA representing a range of sexual maturity states and reproductive states (n = 18 specimens). Presence of skeletal muscle and variation in the density of muscle banding were assessed using 90 histological samples (n = 5 specimens). Analyses of the gross morphological data revealed that the dolphins generally had one large vaginal fold that bisected the vaginal lumen. Vaginal morphology was similar for sexually mature and immature specimens and across reproductive states. The histological data revealed that the vaginal musculature consisted of smooth muscle, consistent with other mammals, leading us to conclude that vaginal contractions are likely under autonomic rather than somatic control. No differences were found in the density of smooth muscle banding among vaginal regions or sexual maturity states. Our systematic protocol lays the foundation for evaluating the function (e.g., sexual selection, natural selection) and evolution of vaginal folds.

Abstract
The gonadotropin-releasing hormone (GnRH) stimulation test is the gold standard for differentiating central precocious puberty (CPP) from exaggerated thelarche (ET). Because of this test's limitations, previous studies have clarified the clinical and laboratory factors that predict CPP. The present study investigated the early diagnostic significance of pelvic ultrasound in girls with CPP. The GnRH stimulation test and pelvic ultrasound were performed between March 2007 and February 2015 in 192 girls (aged <8 years) with signs of early puberty and advanced bone age. Ninety-three of 192 patients (48.4%) were diagnosed as having CPP and the others (51.6%) as having ET. The CPP group had higher uterine volumes (4.31±2.79 mL) than did the ET group (3.05±1.97 mL, p=0.03). No significant differences were found in other ultrasonographic parameters. By use of receiver operating characteristic curve analysis, the most predictive parameter for CPP was a uterine volume of least 3.30 mL, with an area under the curve of 0.659 (95% confidence interval: 0.576-0.736). The CPP group had significantly higher uterine volumes than did the ET group, but there were no reliable cutoff values in pelvic ultrasound for differentiating between CPP and ET. Pelvic ultrasound should be combined with clinical and laboratory tests to maximize its diagnostic value for CPP.

Abstract
BACKGROUND Aromatase deficiency may result in a complete block of estrogen synthesis because of the failure to convert androgens to estrogens. In females, this results in virilisation at birth, ovarian cysts in prepuberty and lack of pubertal development but virilisation, thereafter. OBJECTIVE AND METHODS We studied the impact of oral 17β-estradiol treatment on ovarian and uterine development, and on LH/FSH and inhibin B during the long-term follow-up of a girl harboring compound heterozygote point mutations in the CYP19A1 gene. RESULTS In early childhood, low doses of oral 17β-estradiol were needed. During prepuberty treatment with slowly increasing doses of E2 resulted in normal uterine and almost normal development of ovarian volume, as well as number and size of follicles. Regarding hormonal feedback mechanisms, inhibin B levels were in the upper normal range during childhood and puberty. Low doses of estradiol did not suffice to achieve physiological gonadotropin levels in late prepuberty and puberty. However, when estradiol doses were further increased in late puberty levels of both FSH and LH declined with estradiol levels within normal range. CONCLUSION Complete aromatase deficiency provides an excellent model of how ovarian and uterine development in relation to E2, LH, FSH and inhibin B feedback progresses from infancy to adolescence.

Abstract
Polycystic ovary syndrome (PCOS) is a common condition in women at reproductive age associated with reproductive and metabolic dysfunction. Proposed diagnosed criteria for PCOS include two out of three features: androgen excess, menstrual irregularity, and polycystic ovary appearance on ultrasound (PCO), after other causes of hyperandrogenism and dysovulation are excluded. Based on these diagnostic criteria, the most common phenotypes are the "classic PCOS"--hyperandrogenism and oligomenorrhea, with or without PCO; the "ovulatory phenotype"--hyperandrogenism and PCO in ovulatory women; and the "non-hyperandrogenic phenotype", in which there is oligomenorrhea and PCO, without overt hyperandrogenism. The presence of obesity may exacerbate the metabolic and reproductive disorders associated with the syndrome. In addition, PCOS women present higher risk for type 2 diabetes and higher prevalence of cardiovascular risk factors that seems to be associated with the classic phenotype. The main interventions to minimize cardiovascular and metabolic risks in PCOS are lifestyle changes, pharmacological therapy, and bariatric surgery. Treatment with metformin has been shown to improve insulin sensitivity, lowering blood glucose and androgen levels. These effects are more potent when combined with lifestyle interventions. In conclusion, besides reproductive abnormalities, PCOS has been associated to metabolic comorbidities, most of them linked to obesity. Confounders, such as the lack of standard diagnostic criteria, heterogeneity of the clinical presentation, and presence of obesity, make management of PCOS difficult. Therefore, the approach to metabolic abnormalities should be tailored to the risks and treatment goals of each individual woman.

Abstract
STUDY OBJECTIVE To evaluate biological differences among young subjects with premature ovarian insufficiency (POI) commencing at different stages of life. DESIGN Retrospective observational study. SETTING Careggi University Hospital Participants: One hundred sixty-two females aged between 15 and 29 years with premature ovarian insufficiency. METHODS Data were collected as a retrospective chart review of baseline evaluation at diagnosis of premature ovarian insufficiency (POI). About 162 participants were divided into four groups based on gynecological age. Two primary outcome variables (uterine development and bone mineral density (BMD)) were analyzed in terms of differences among groups and in a multivariate logistic regression analysis. RESULTS Uterine development was clearly jeopardized when estrogen insufficiency started at a very young age. Total body BMD showed significant differences among the four groups studied, clearly corresponding to the duration of ovarian function. Data were discussed in relation to the choice of hormone replacement therapy regimens.

Abstract
OBJECTIVE We aimed to investigate safety and effectiveness of a conservative approach for complex neonatal ovarian cysts and its long term impact on fertility. STUDY DESIGN Neonates with congenital complex ovarian cysts were conservatively managed and followed from the perinatal period to adolescence. Statistical analysis included Student's t-test, Mann-Whitney U-test, the Kaplan-Meier method, and the receiver operating characteristic curve. RESULTS The post-natal progressive dimensional reduction of diagnosed ovarian cyst was statistically significant. The Kaplan-Meier survival curves revealed the probability of persistence of the cyst was up to 5% at the age of 25 months. Long term follow-up revealed both ovaries visible at US in 60% of adolescent patients. CONCLUSION Conservative management of asymptomatic complex neonatal ovarian cysts can be safely undertaken. As far as the chances of the ovarian tissue to survive conservative treatment are concerned, the results are not encouraging.

Abstract
The daughter cyst sign is a specific indicator of an uncomplicated ovarian cyst and pathologically represents a stimulated ovarian follicle. This finding must be differentiated from an ectopic pregnancy in a patient who has the potential to become pregnant. We report an uncomplicated ovarian cyst in a 3-year-old female with McCune-Albright syndrome and precocious puberty mimicking an ectopic pregnancy.

Abstract
PURPOSE To evaluate the role of pelvic sonography (US) in the diagnosis and differentiation of various forms of precocious puberty in girls, and to explore reliable cutoff points of pelvic US measurements for differentiating between these conditions. METHODS Uterine length, uterine cross-sectional area, uterine volume, fundocervical ratio, and ovarian volumes of 143 healthy girls were compared with those of 125 girls with different forms of sexual precocity. Ovaries were morphologically classified as homogenous, paucicystic, multicystic, macrocystic, and isolated cystic. RESULTS Almost all US measurements of girls with central precocious puberty in the 0- to 8-year age group were significantly increased compared with controls and girls with premature thelarche and adrenarche (p < 0.05, except for ovarian volumes in premature thelarche group), whereas no statistically significant difference was found in the 8- to 10-year group (p > 0.05). Ovarian morphology distributions did not differ significantly between patient subgroups, but all had more mature forms compared with controls. Due to the wide overlap between the measurements, no reliable cutoff points could be determined by charting receiver operating characteristics curves. CONCLUSIONS Pelvic US can improve the diagnosis of central precocious puberty in girls of 0-8 years of age but provides no reliable type differentiation alone. It provides no valuable information for this diagnosis in girls of 8-10 years of age.

Abstract
OBJECTIVE The aim of this study was to evaluate the girls referred to the pediatric outpatient clinic with a presumptive diagnosis of early puberty due to early onset of breast development or pubarche. METHODS Within the study period, we evaluated 289 subjects referred for concerns about early onset of puberty. History, anthropometric data, bone age (BA), hormones including luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol, and dehydroepiandrosterone sulfate, as well as pelvic ultrasonography (USG)-derived ovarian and uterine volumes were analyzed. RESULTS Of the 289 girls referred for early onset of pubertal development, 64 (22.1%) had false alarms for puberty. Of the remaining 225 girls, 41 (18.2%) were diagnosed as premature pubarche, 56 (24.9%) as premature thelarche (PT), and 128 (56.9%) as precocious puberty (PP). Girls with early-onset puberty had more advanced BA, greater uterine and ovarian volumes, and also higher LH values than subjects with PP and PT. Nearly half of these girls were 7-8 years of age. Body mass index (BMI) standard deviation score was significantly higher in the PP cases. CONCLUSIONS There is a need for primary care physicians to be more knowledgeable on puberty and on puberty problems. There seems to be a preponderance of PP in 7-8-year-old children . Increased BMI may have a role in the trend towards earlier onset of puberty.

Abstract
Puberty is the period of biologic transition from childhood to adulthood. The changes that occur at this time are related to the increasing concentrations of sex steroid hormones. In females, most pubertal changes are caused by estrogen stimulation that results from the onset of central puberty. Significant development occurs in the organs of the female reproductive system and results in anatomic changes that characterize reproductive maturity. Adrenal and ovarian androgens also increase during puberty, affecting change that includes the promotion of certain secondary sex characteristics. The ability to recognize normal pubertal anatomy and distinguish between estrogen and androgen effects is important in the ability to diagnose and treat disorders of sex development, precocious puberty, pubertal delay, and menstrual irregularities in children and adolescents. An understanding of this developmental process can also help clinicians identify and treat reproductive pathology in adults and across all female life stages.

Abstract
BACKGROUND McCune-Albright syndrome is a rare syndrome, classically defined as the triad of precocious puberty, fibrous dysplasia of bone, and café au lait lesions. Partial or atypical presentations of McCune-Albright syndrome, with only one or two of the classic symptoms, have been described in the literature and remain particularly challenging due to lack of diagnostic phenotype. In these patients, the utility of analysis of mutations in the gene of the α subunit of the stimulatory G-protein is limited and so the diagnosis is often based on clinical judgment. Three atypical cases of suspected McCune-Albright syndrome with gonadotropin-independent precocious puberty are presented. CASES Case #1: A 5-year-old female presented with painlesss vaginal bleeding and was found to have café au lait lesions. She was diagnosed with gonadotropin independent precocious puberty with eventual progression to gonadotropin dependent precocious puberty which was successfully treated with both letrozole and gonadotropin-releasing hormone agonist therapy. Case #2: A 3-year-old female presented with painless vaginal bleeding and was found to have café au lait lesions. She was diagnosed with gonadotropin independent precocious puberty and was successfully treated with letrozole. Case #3: A 5-year-old female presented with fibrous dysplasia and was found to have evidence of uterine and ovarian enlargement on ultrasound. She was diagnosed with gonadotropin-independent precocious puberty and was successfully treated with letrozole. SUMMARY AND CONCLUSION Although different in presentation, all three atypical cases of suspected McCune-Albright syndrome with gonadotropin-independent precocious puberty were successfully treated with aromatase inhibitors. This small case series shows the utility and efficacy of aromatase inhibitors in the setting of atypical cases of suspected MAS with gonadotropin-independent precocious puberty.

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
OBJETIVO: Os cistos aracnoides são achados raros. Em 10% dos casos, sua localização é supraselar e ocorrem quase exclusivamente em crianças. Em geral, apresentam manifestações neurológicas e visuais, sendo incomum a puberdade precoce central como sinal clínico de sua presença. DESCRIÇÃO DO CASO: Menina avaliada aos dois anos e sete meses por telarca iniciada com um ano e oito meses e pubarca e axilarca com dois anos, com aumento da velocidade de crescimento (13cm/ano) e da idade óssea (sete anos e um mês). Ao exame, apresentou peso de 22,6kg (Z+4,0), estatura de 106cm (Z+3,5) e Tanner de M3P2. Exames realizados: teste de estímulo com GnRH (LH basal 8,3 UI/L, pico aos 30 minutos 94,3 UI/L; FSH basal=10,1 UI/L, pico aos 30 minutos 29,5 UI/L), ressonância nuclear magnética de crânio com cisto aracnoide supraselar e demais testes de função hipofisária normais. Foi iniciado tratamento com análogo de GnRH. Atualmente, aos quatro anos e três meses com estadio puberal M3P2, velocidade de crescimento e desenvolvimento neuropsicomotor normais para a idade. COMENTÁRIOS: A puberdade precoce central pode ser manifestação única de um cisto aracnoide, sendo essenciais o diagnóstico e o tratamento precoces, além de seguimento prolongado, uma vez que outras disfunções hipofisárias podem ocorrer tardiamente.

Abstract
BACKGROUND To provide normal references of sonographic uterine and ovarian size in premenarcheal healthy girls aged 6-13 years in different stages of puberty. METHODS Two hundred forty girls were enrolled into the study (mean age ± SD, 9.5 ± 1.7 years [range, 6-13.5 years]). Pubertal status was classified according to Tanner staging. All subjects underwent pelvic sonographic examination for the measurement of uterine volume, body and cervical length, anteroposterior diameter of fundus, body, and cervix, ovarian volume, and both right and left prominent follicular diameter. RESULTS A gradual increase with age was observed in all uterine and ovarian measurements. Both uterine and ovarian parameters were significantly correlated to age, height and weight, and stages of puberty. Uterine volume was <3.5 cm(3) in 98% of prepubertal girls, and in stage 2 it was significantly more than in stage 1 (3 ± 3.2 versus 1.7 ± 1.7, respectively) (p < 0.001). Uterine body length was also significantly greater in stage 2 than stage 1 (17.5 ± 4.5 versus 14.6 ± 3.3, respectively) (p < 0.001). CONCLUSION The reference values for uterus and ovaries were determined in healthy girls. There is a progressive increase in size of internal female genitalia in relation to age, height, weight, and puberty. Uterine volume and body length presented the best correlation with age and stage of puberty.

Abstract
BACKGROUND/PURPOSE The aims of this study were to evaluate survival and ovarian prognosis in patients treated for ovarian germ cell tumor (OGCT) and to propose a decision-making protocol. METHODS Charts of girls operated on for OGCT from 1976 up to 2009 were reviewed retrospectively. Tumor characteristics were assessed by tumor markers, imaging, and pathology. RESULTS Charts were available in 71 children presenting 75 OGCT. Tumors were benign in 58 cases and malignant in 17 cases. The average of the largest diameter of benign OGCT was significantly lower than that of malignant OGCT (76.5 +/- 49 mm versus 169 +/- 54 mm, P < .0001). Ovarian-sparing tumorectomy was carried out in 27 benign OGCT; 23 (85%) preserved ovaries were follicular. Malignant OGCTs were managed according to the protocols of the French Society for Pediatric Oncology. Bilateral oophorectomy had to be performed in 2 children. One patient presented a recurrence and 1 died. CONCLUSIONS In our series, both benign and malignant OGCTs have a good prognosis. A 75-mm cutoff size is proposed as an important criterion to preoperatively differentiate between benign and malignant tumors. In benign OGCT, ovarian-sparing tumorectomy leads to preserve ovaries in approximately 85% of cases, and in malignant OGCT, high survival rate has been obtained.

Abstract
BACKGROUND/PURPOSE Ovarian torsion in childhood and adolescence is a rare entity. Traditionally, treatment is oophorectomy. The aim of this study was to evaluate ovarian outcome and to propose a decision-making protocol for suspected ovarian torsion. METHODS Between January 1986 and December 2007, 45 ovarian torsion cases in 40 girls were operated on. In all the cases, when the ovary was preserved, patients were clinically and ultrasonographically followed up for several months. RESULTS Median age was 11 years. Median delay between the first symptoms and surgical procedure was 3 days. There was a statistical difference (P = .0003) between the mean of the largest diameter of twisted normal ovary and the mean of the largest diameter of twisted diseased ovary. Underlying pathology was benign in 22 cases and low-grade malignancy in 2 (one grade II immature teratoma and one steroid cell tumor). Conservative management was performed in 26 cases. At follow-up, 17 ovaries were follicular, 7 being black-bluish during surgery. CONCLUSIONS Conservative approach after detorsion of black-bluish ovaries is safe and effective in children. Although very unlikely, the fear of missing malignancy must incite to proceed with caution and can lead, when the size of the twisted ovary is greater than 75 mm, to prefer laparotomy to laparoscopy.

Abstract
STUDY OBJECTIVE To study evidence of polycystic ovary syndrome (PCOS) in premenarcheal adolescents with unexplained ovarian torsion. DESIGN Retrospective observational case series. SETTING Tertiary university clinical center PARTICIPANTS Six premenarcheal adolescents and six adults with acute ovarian torsion INTERVENTION A chart review. MAIN OUTCOME MEASURES Contralateral ovarian size, operative findings, ovarian pathology, hormone testing RESULTS Five of the six premenarcheal cases had no pathologic explanation for their ovarian torsion. In four of the cases, size measurements of the contralateral ovary were noted to be larger than the criterion of their respective age group. Three of the four cases had either an ovarian volume (28.5 cm(3)) or an area (16.0 cm(2) and 57.6 cm(2)) that was above the size criterion for a polycystic ovary (volume >10 cm(3) or area>5.5 cm(2)). Pathology of a wedge biopsy of one of the contralateral ovaries suggested evidence of polycystic ovary. Finally, hormone testing available in three of the cases revealed elevated testosterone levels in two. Among the adults, half of the cases had a pathologic explanation for ovarian torsion. One out of the five cases had a contralateral ovary that was significantly enlarged and this was noted in a woman with a diagnosis of PCOS. The remaining two cases had extensive necrosis of the torsed ovary and no other diagnosis was made. CONCLUSION We propose that premenarcheal girls presenting with ovarian torsion, without obvious ovarian pathology, be screened for ultrasound and biochemical evidence of PCOS. In those with evidence of PCOS, treatment with oral contraceptives should be considered taking into account the age and pubertal development, to decrease ovarian volume.

Abstract
PURPOSE To provide normal references of sonographic uterine and ovarian size in girls aged 1-12 years. METHOD Ninety-nine girls were enrolled in the study (mean age +/- SD, 6.9 +/- 2.4 years [range, 1-12 years]). Pubertal status was classified according to Tanner staging, whereas for height and weight assessment a standard stadiometer and weight scale were employed. All subjects underwent pelvic sonographic examination for the measurement of uterine length, volume, ratio of anteroposterior diameter at the fundus divided by the anteroposterior diameter at the cervix (fundal-cervical [F/C] ratio), and ovarian volume and morphology. RESULTS A gradual increase with age was observed in all uterine and ovarian measurements. Cubic model analysis provided the best curve estimation for uterine length, uterine volume, and ovarian volume in relation to age. Uterine length, uterine volume, ovarian volume and F/C ratio were significantly correlated to both age and height. With respect to ovarian morphology, there was a gradual decrease in frequency of the homogeneous and the paucicystic appearances with increasing age. The macrocystic appearance was observed after the age of 6 years, and its frequency increased gradually with age. CONCLUSION There is a continuous increase in size of internal female genitalia from early childhood until the onset of puberty. We have provided reference percentile charts of normal uterine length, uterine volume, and ovarian volume in girls aged 1-12 years.

Abstract
OBJECTIVES This study was conducted to assess the role of pelvic ultrasound variables in discriminating between normal girls and girls with different forms of sexual precocity, and to establish reliable cut-off limits of pelvic ultrasound measurements for differentiating between these conditions. METHODS Eighty-eight girls with different forms of sexual precocity (23 with premature thelarche, 15 with premature pubarche and 50 with central precocious puberty) were enrolled. All diagnoses were based on clinical examination with confirmation using the gonadotropin-releasing hormone-stimulation test. Additionally, 81 prepubertal girls, aged 0-10 years, were included as a control group. For statistical analysis and to facilitate comparisons, the groups were subdivided by age intervals (0-6, > 6-8 and > 8-10 years). All subjects underwent pelvic ultrasound examination for the measurement of uterine length, uterine volume, ovarian volume and the anteroposterior diameter at the fundus divided by the anteroposterior diameter at the cervix (fundal/cervical ratio, (F/C)). Finally, the morphological appearance of the ovaries was assessed. RESULTS Patients with central precocious puberty had significantly higher values for all the ultrasound variables (with the exception of uterine length in the 1-6-year age group) in comparison to normal girls. Patients with premature thelarche and patients with premature pubarche showed similar pelvic ultrasound parameters to those of normal girls. Ovarian volume was the best parameter for identifying patients with central precocious puberty (a cut-off of 3.04 cm(3) had a sensitivity of 100% and a specificity of 97.1% for age interval 0-6 years, a cut-off of 3.35 cm(3) had a sensitivity of 100% and a specificity of 89.5% for age interval > 6-8 years, and a cut-off of 4.46 cm(3) had a sensitivity of 80.8% and a specificity of 88.5% for age interval > 8-10 years). Uterine length was the best parameter for distinguishing between patients with central precocious puberty and patients with premature thelarche (a cut-off of 3.185 cm had a sensitivity of 85.7% and a specificity of 91.7% for age interval 0-6 years, and a cut-off of 3.83 cm had a sensitivity of 82.4% and a specificity of 90.9% for age interval > 6-8 years). CONCLUSIONS Ultrasound examination of the uterus and ovaries could serve as a complementary tool for the diagnosis of central precocious puberty and, consequently, for the early initiation of appropriate treatment.

Abstract
BACKGROUND/PURPOSE Fetal ovarian cysts are frequently complicated by intracystic hemorrhage without associated clinical signs, which is often secondary to ovarian torsion leading to loss of the ovary. The aim of this study was to evaluate ovarian outcome and the place of prenatal management and surgery in the first few days of life in order to save the ovary. METHODS Between January 1987 and June 2006, 82 fetal ovarian cysts in 79 patients were managed and clinically and ultrasonographically followed up for several months (median, 11 months; range, 6 months to 10 years) in all of the cases where the ovary was not removed. The ultrasonographic results regarding the ovarian parenchyma were broken down into 3 categories: follicular ovary, homogeneous ovary, and undetected ovary. RESULTS Twenty-seven cysts remained simple throughout their evolution, and 55 were complicated by intracystic hemorrhage usually several weeks before birth. Overall, after disappearance of the cyst, a follicular ovary was detected in only 39% of the cases (32/82) and more often when the cyst was simple than when it presented an intracystic hemorrhage (85% vs 16.4%, chi(2), P < .0001). CONCLUSIONS A review of our series confirms the poor ovarian outcome linked to ultrasonographic signs of intracystic hemorrhage. Preventive action by puncture of "simple" cysts is still being studied. The presence of a bilateral cyst can, if pulmonary maturity has been reached, be an argument for inducement of premature birth with a view to performing conservative surgery. After birth, surgery in the first few days of life is only justified if the signs of intracystic hemorrhage appeared in the period very close to birth.

Abstract
INTRODUCTION The authors describe and discuss the clinical and therapeutic features of 40 ovarian torsions (OT) in children with its urgent treatment that has advanced in recent years. MATERIALS AND METHODS A retrospective study of 40 cases of OT in 38 children under 16 years of age, excluding adnexal torsions in neonates. RESULTS Abdominal and/or pelvic pain was the presenting symptom ; 8 of these children had pain between 2 to 9 months prior to surgery and 27/40 (67.5%) had associated vomiting. Before the procedure, ultrasound (US) diagnosed 29 ovarian lesions, related to 14 mature teratomas (MTE) and 10 cystadenomas (CA), one association of MTE and CA in the same ovary, 2 functional cysts and 2 malignant neoplasms. 19/40 torsions could benefit from conservative management. Eleven torsions occurred, 10/11 of these ovaries had an increased volume, and 5/11 had US evidence of small subcortical cysts. Three detorsions with incomplete removal of CA were followed by enlargement of the tumor and re-torsion in 2 of them. Five children had bilateral ovarian pathology which led to unilateral ovariectomy, while the other benefited from conservative treatment. CONCLUSIONS In any girl presenting with abdominal pain, the diagnosis of an ovarian torsion must be considered. US is performed emergently, but only surgery, most often a laparoscopic procedure, assures diagnosis. The treatment of the torsion is an emergency and must be as conservative as possible in order to preserve the ovarian function. Bilateral torsions are not unusual.

Abstract
We investigated the presence of mutations/polymorphisms in the FSH receptor (FSHR) gene and their association with phenotype in women with premature ovarian failure (POF) in southern Brazil. Clinical and hormonal variables were determined in 36 46,XX women with primary or secondary amenorrhea before the age of 40 yr, FSH >40 IU/l and ovarian failure. DNA was isolated from peripheral leukocytes. Exons 6, 7, 9, and 10 of the FSHR gene were analyzed by PCR, restriction enzyme analysis, denaturing gradient gel electrophoresis, and direct sequencing. No inactivating mutations were found. Exon 10 had two polymorphisms, Ala307Thr and Ser680Asn (allelic frequency: 52.9 and 35.7%, respectively), which were not related to FSH, LH or estradiol serum levels. Ovarian size and small ovarian follicles on transvaginal sonography were not associated with FSHR genetic variants. In contrast, the last menstruation occurred significantly earlier in patients with the Ala307Thr polymorphism (A: age=33.3+/-7.1 yr vs T: 28.6+/-11.4 yr, p=0.04). In conclusion, we did not identify inactivating mutations in exons 6, 7, 9, and 10 of the FSHR gene. A high frequency of two polymorphisms that are in linkage disequilibrium was found in exon 10 of the FSHR gene. The presence of the Ala307Thr polymorphism may be associated with a more precocious onset of clinical disease.

Abstract
OBJECTIVE Reduced growth before birth is known to associate with a smaller ovarian volume in adolescents and women without androgen excess. We studied whether prenatal growth relates also to ovarian size and polycystic ovary (PCO) morphology in nonobese adolescents and young women with ovarian androgen excess. DESIGN A cross-sectional analysis of standardized case notes over a 2-yr period was performed. PATIENTS Nonobese adolescents and young women (age approximately 17 yr; n = 86) seen for ovarian androgen excess, as confirmed by 17-hydroxy-progesterone hyperresponse to a GnRH agonist, were included in the study. MEASUREMENTS Endocrine-metabolic assessment in fasting state, together with a vaginal ultrasound scan to verify the presence or absence of PCO was performed. Birth weight and gestational age were derived from medical records. RESULTS PCO prevalence by ultrasound was 38%. Absence of PCO was associated with a shift (P < 0.0005) of the birth weight distribution toward lower values. Patients with a birth weight less than 3.0 kg were 6-fold more likely to have no PCO than to have PCO. Birth weight was across a wide range (1.5-4.0 kg) associated with ovarian volume in hyperandrogenic patients with noncystic ovaries (r = 0.60; P < 0.00001) and was, in a multiple regression analysis, the prime variable linked to ovarian volume (beta = 0.57; P < 0.00001), explaining 32% of its variance. CONCLUSIONS The ovarian size and the development of a PCO morphology in nonobese adolescents and young women with ovarian androgen excess relate to prenatal growth. These findings indicate that there are two subgroups of nonobese patients with ovarian androgen excess: one with a normal birth weight distribution and with PCO, and one with lower birth weights and without PCO.

Abstract
PURPOSE To describe a Gender Assessment Team that has provided a multidisciplinary approach to the diagnosis, medical and surgical treatment, genetic counseling, and psychosocial support of patients with ambiguous genitalia, intersex disorders, and other genital anomalies, collectively termed disorders of sex development; and to determine the major diagnostic categories and approach. METHODS A retrospective review of 250 patients evaluated by the Team at Children's Hospital and Regional Medical Center in Seattle, WA, from January 1981 through December 2005. The Team included the following specialties: medical genetics, cytogenetics, gynecology, pediatric urology, endocrinology, and psychiatry. RESULTS Of the subjects, 177 were infants, 46 were children or adolescents, and 27 had a multisystem genetic condition. The most common diagnoses were congenital adrenal hyperplasia (14%), androgen insensitivity syndrome (10%), mixed gonadal dysgenesis (8%), clitoral/labial anomalies (7%), hypogonadotropic hypogonadism (6%), and 46,XY small-for-gestational-age males with hypospadias (6%). CONCLUSION The six most common diagnoses comprised 50% of the cohort. The expertise of a multidisciplinary team allowed for integrated care for patients with disorders of sex development and identification of novel conditions. Geneticists play an important role in a team approach through knowledge of genetic testing options and diagnosis of patients with karyotypic abnormalities and syndromes with genital anomalies.

Abstract
OBJECTIVE The objective of this study was to gather data on the morphology of the uterus during its development, to provide detailed information regarding the neighboring structures and its variations using anatomical dissections. STUDY DESIGN Eighty uteri acquired from female fetuses aged 10-40 weeks of gestation were used in this study. Firstly, the relationship between the fetal uterus and the linea terminalis and the position of the uterus within the pelvic cavity was noted. Then the distance between the fundus of the uterus to the promontory and pubic symphysis were measured. Fetal uteri were classified according to their physical appearances. Finally the lengths of the corpus and cervix in three planes and the anteflexion angle were measured. RESULTS During the fetal period, the fundus of the uterus was above the linea terminalis in 94% and below it in 6% of the cases. The distance between the fundus of the uterus and the promontory significantly correlated with the distance between the fundus of the uterus and the pubic symphysis (p<0.001). This was true for the correlation between the gestational age and the orthogonal lengths of the uterine corpus and cervix (p<0.001). As the gestational age advanced, the anteflexion angle was noted to reduce from 177 degrees to 120 degrees . The shape of the uterus was either cylindrical, pear-shaped, heart-shaped or hourglass-shaped during the fetal period. CONDENSATION We believe that the data obtained through dissections of the human fetuses in this study will help identifying uterine developmental variations, anomalies and pathologies and will contribute to the studies carried out in obstetrics, perinatology, forensic medicine and fetal pathology departments.

Abstract
In this work, we provide preliminary data and a review of the literature regarding normal structural and functional changes that occur in the aging uterus, ovary, testicle, and prostate gland. It is expected that such knowledge will help physicians to distinguish physiologic changes from pathologic changes at an early stage. We retrospectively reviewed pelvic magnetic resonance imaging (MRI) scans of 131 female and 79 male subjects ages 13 to 86 years to determine changes in volume of the uterus, ovary, and prostate gland with age. Scrotal ultrasound examinations of 150 male subjects ages 0 to 96 years also were analyzed retrospectively to determine changes in testicular volume with age. In addition, (18)F-fluorodeoxyglucose positron emission tomography ((18)F-FDG-PET) scans of 145 male subjects ages 11 to 90 years were analyzed retrospectively to assess for changes in maximum standardized uptake value (SUV(max)) of the testicles with age. The uterus had a mean volume of 38.55 +/- 3.68 cm(3) at 17 to 19 years of age, increased to a peak volume of 71.76 +/- 19.81 cm(3) between 35 to 40 years, and then declined to 24.02 +/- 8.11 cm(3) by the eighth decade of life. The maximal ovarian volume per subject maintained a relatively stable size in early life, measuring 9.46 +/- 3.25 cm(3) during the second decade of life, 8.46 +/- 3.32 cm(3) in the mid-fourth decade of life, and 7.46 +/- 3.33 cm(3) at 45 years of age, after which it declined to 4.44 +/- 2.02 cm(3) by the late fifth decade of life. The ovaries were not identifiable on MRI in subjects beyond the sixth decade of life. The volume of the prostate increased from 23.45 +/- 6.20 cm(3) during the second decade of life to 47.5 +/- 41.59 cm(3) by the late eighth decade of life; the central gland of the prostate increased from 9.96 +/- 3.99 cm(3) to 29.49 +/- 28.88 cm(3) during the same age range. Mean testicular volume was 11.2 +/- 5.9 cm(3). Testicular volume increased with age from birth to 25 years. After age 25, there was a significant decline in the testicular volume. The mean SUV(max) for the testicles was 1.9 +/- 0.5. Testicular metabolic activity demonstrated an increasing trend until the age of 35 years. A plateau in SUV(max) was observed after the age of 35 years until the age of 65 years. A slight decrease in SUV(max) was observed after the age of 65 years. The pelvic structures of men and women change both structurally and functionally over the lifespan, and such changes can be quantified using ultrasound, MRI, and (18)F-FDG-PET.
