RESUMO

Importance: Although most ovarian masses in children and adolescents are benign, many are managed with oophorectomy, which may be unnecessary and can have lifelong negative effects on health. Objective: To evaluate the ability of a consensus-based preoperative risk stratification algorithm to discriminate between benign and malignant ovarian pathology and decrease unnecessary oophorectomies. Design, Setting, and Participants: Pre/post interventional study of a risk stratification algorithm in patients aged 6 to 21 years undergoing surgery for an ovarian mass in an inpatient setting in 11 children's hospitals in the United States between August 2018 and January 2021, with 1-year follow-up. Intervention: Implementation of a consensus-based, preoperative risk stratification algorithm with 6 months of preintervention assessment, 6 months of intervention adoption, and 18 months of intervention. The intervention adoption cohort was excluded from statistical comparisons. Main Outcomes and Measures: Unnecessary oophorectomies, defined as oophorectomy for a benign ovarian neoplasm based on final pathology or mass resolution. Results: A total of 519 patients with a median age of 15.1 (IQR, 13.0-16.8) years were included in 3 phases: 96 in the preintervention phase (median age, 15.4 [IQR, 13.4-17.2] years; 11.5% non-Hispanic Black; 68.8% non-Hispanic White); 105 in the adoption phase; and 318 in the intervention phase (median age, 15.0 [IQR, 12.9-16.6)] years; 13.8% non-Hispanic Black; 53.5% non-Hispanic White). Benign disease was present in 93 (96.9%) in the preintervention cohort and 298 (93.7%) in the intervention cohort. The percentage of unnecessary oophorectomies decreased from 16.1% (15/93) preintervention to 8.4% (25/298) during the intervention (absolute reduction, 7.7% [95% CI, 0.4%-15.9%]; P = .03). Algorithm test performance for identifying benign lesions in the intervention cohort resulted in a sensitivity of 91.6% (95% CI, 88.5%-94.8%), a specificity of 90.0% (95% CI, 76.9%-100%), a positive predictive value of 99.3% (95% CI, 98.3%-100%), and a negative predictive value of 41.9% (95% CI, 27.1%-56.6%). The proportion of misclassification in the intervention phase (malignant disease treated with ovary-sparing surgery) was 0.7%. Algorithm adherence during the intervention phase was 95.0%, with fidelity of 81.8%. Conclusions and Relevance: Unnecessary oophorectomies decreased with use of a preoperative risk stratification algorithm to identify lesions with a high likelihood of benign pathology that are appropriate for ovary-sparing surgery. Adoption of this algorithm might prevent unnecessary oophorectomy during adolescence and its lifelong consequences. Further studies are needed to determine barriers to algorithm adherence.

RESUMO

BACKGROUND: Management of ovarian torsion has evolved toward ovarian preservation regardless of ovarian appearance during surgery. However, patients with torsion and an ovarian neoplasm undergo a disproportionately high rate of oophorectomy. Our objectives were to identify factors associated with ovarian torsion among females with an ovarian mass and to determine if torsion is associated with malignancy. METHODS: A retrospective review of females aged 2-21 y who underwent an operation for an ovarian cyst or neoplasm between 2010 and 2016 at 10 children's hospitals was performed. Multivariate logistic regression was used to assess factors associated with torsion. Imaging data were assessed for sensitivity, specificity, and predictive value in identifying ovarian torsion. RESULTS: Of 814 girls with an ovarian neoplasm, 180 (22%) had torsion. In risk-adjusted analyses, patients with a younger age, mass size >5 cm, abdominal pain, and vomiting had an increased likelihood of torsion (P < 0.01 for all). Patients with a mass >5 cm had two times the odds of torsion (odds ratio: 2.1; confidence interval: 1.2, 3.6). Imaging was not reliable at identifying torsion (sensitivity 34%, positive predictive value 49%) or excluding torsion (specificity 72%, negative predictive value 87%). The rates of malignancy were lower in those with an ovarian mass and torsion than those without torsion (10% versus 17%, P = 0.01). Among the 180 girls with torsion and a mass, 48% underwent oophorectomy of which 14% (n = 12) had a malignancy. CONCLUSIONS: In females with an ovarian neoplasm, torsion is not associated with an increased risk of malignancy and ovarian preservation should be considered.

RESUMO

PURPOSE: The purpose of this study was to determine the diagnostic accuracy of tumor markers for malignancy in girls with ovarian neoplasms. METHODS: A retrospective review of girls 2-21 years who presented for surgical management of an ovarian neoplasm across 10 children's hospitals between 2010 and 2016 was performed. Patients who had at least one concerning feature on imaging and had tumor marker testing were included in the study. Sensitivity, specificity, and negative and positive predictive values (PPV) of tumor markers were calculated. RESULTS: Our cohort included 401 patients; 22.4% had a malignancy. Testing for tumor markers was inconsistent. AFP had high specificity (98%) and low sensitivity (42%) with a PPV of 86%. The sensitivity, specificity, and PPV of beta-hCG was 44%, 76%, and 32%, respectively. LDH had high sensitivity (95%) and Inhibin A and Inhibin B had high specificity (97% and 92%, respectively). CONCLUSIONS: Tumor marker testing is helpful in preoperative risk stratification of ovarian neoplasms for malignancy. Given the variety of potential tumor types, no single marker provides enough reliability, and therefore a panel of tumor marker testing is recommended if there is concern for malignancy. Prospective studies may help further elucidate the predictive value of tumor markers in a pediatric ovarian neoplasm population. TYPE OF STUDY: Retrospective Cohort Review. LEVEL OF EVIDENCE: Level III.

RESUMO

STUDY OBJECTIVE: To describe how pediatric and adolescent patients present to the gynecologist when they have tethered cord syndrome (TCS). DESIGN: We conducted a retrospective chart review on all patients suspected by the gynecologist of having TCS. SETTING: Single pediatric and adolescent gynecology clinic in a mid-sized city in the midwest. PARTICIPANTS: Thirty-two patients, first seen between 2005 and 2012, suspected of having TCS and for whom follow-up information was available. INTERVENTIONS AND MAIN OUTCOME MEASURES: Patient characteristics, including patient history, gynecologic clinical indicators, clinical outcomes, indications for surgery, and postoperative resolution of symptoms, were reviewed. RESULTS: The initial review of systems indicated stress urinary incontinence, back pain, and constipation as common markers in the 32 patients who were suspected of having TCS. All 32 patients underwent lumbar magnetic resonance imaging without contrast and evaluation by neurosurgery. Of the 32 patients with suspected TCS, 18 were later confirmed and 14 were shown to not have TCS. Of the 18 patients with sufficient information to justify a detethering procedure, 14 patients were followed and 93% (13 patients) had complete resolution of symptoms. Final diagnosis in the non-TCS group varied, including vulvovaginitis, enuresis, chronic constipation, and lichen sclerosis. Symptoms improved with the treatment of each primary condition. CONCLUSIONS: TCS symptoms overlap with gynecologic conditions; therefore, patients with TCS may present initially to the gynecologist. In pediatric/adolescent patients, TCS should be considered when stress urinary incontinence, back pain, and constipation are discovered in the review of systems. Because possible irreversible ischemic and neurologic changes are believed to be involved, early diagnosis and surgery are crucial for resolution. Providers should be aware of TCS in these pediatric and adolescent settings, because quick assessment may result in complete resolution of a chronic progressive disease.

RESUMO

PROBLEM: To examine predictors of intention to seek mental health treatment for adolescent girls in mothers and daughters. METHODS: In this cross-sectional study, mothers and adolescent daughters (n = 71) completed measures of behavioral attitudes, subjective norms, perceived behavioral control, and intention to seek mental health treatment for the adolescent daughter. FINDINGS: Behavioral attitude and perceived behavioral control predicted intention to seek mental health treatment among mothers. Behavioral attitude predicted intention among daughters. There were no associations between mothers and daughters on study variables. CONCLUSIONS: To promote shared decision making and engagement in mental health treatment, clinicians may target interventions to the mother's perceived behavioral control and behavioral attitudes of daughters and mothers. Based upon study results, clinicians should promote shared decision making and concordance between mothers and daughters on attitudes toward mental health treatment.

RESUMO

STUDY OBJECTIVE: The purpose of this study was to evaluate our adolescent patient population who had received a levonorgestrel intrauterine system (LNG-IUS) at or after the time of endometriosis diagnosis, and determine efficacy of the LNG-IUS in regards to pain and bleeding on follow-up exam. DESIGN: Retrospective cohort study. SETTING: Pediatric Adolescent Gynecology Clinic and Children's Hospital in a metropolitan area. PARTICIPANTS: Adolescent patients age 14-22 with pathology-proven endometriosis who had the LNG-IUS placed during the course of their treatment for this disease. Patients were divided into LNG-IUS placement at the time of surgical diagnosis versus placement some time after diagnosis. MAIN OUTCOME MEASURES: Pain and bleeding were assessed by follow-up exam. Pain was classified at each follow-up visit as either none, minimal, moderate, or severe. Bleeding was classified as none, irregular spotting, irregular bleeding, or daily bleeding. RESULTS: The majority of patients (67%) required additional hormonal therapy for pain and bleeding suppression. Time to bleeding suppression and pain suppression was sooner in the group with interval time between surgical diagnosis and LNG-IUS placement, compared to LNG-IUS placement at the time of surgery (2.4 months vs 5.3 months until bleeding suppression, and 3.8 months vs 4.8 months until pain suppression), although statistical significance was not achieved. CONCLUSIONS: The LNG-IUS is an option for treatment of endometriosis in adolescents. As pain is the main problem associated with endometriosis, LNG-IUS placement is beneficial at the time of surgery when it is diagnosed. A prospective study is needed for further assessment of outcomes.

RESUMO

A resolution to the difficulties faced by parents, physicians, and pediatric patients in treating DSDs will only come with better communication and improved research methodologies. Advocacy groups and the Internet have allowed the intersex community to have a larger role in guiding the research and the ethical frameworks that are used in treating these disorders. These disorders are unusual and collaboration across medical centers should be the rule rather than the exception. When possible, treatments that are innovative or experimental should be subjected to rigorous research oversight [29,30]. Defined periods of family crisis in which counseling and education become important are at the time of diagnosis [30,31], at the time of any surgical procedure, and at the beginning of major developmental stages. Historically, children were often left uninformed until someone judged them old and mature enough to comprehend how they were different. These attempts to protect individual children from their condition may have left them vulnerable to a personal crisis at an age when sexual identity and identity with a peer group are important. Both the needs of the child and the adult the child will become should be considered in making treatment decisions for children and adolescents with DSDs. It is best to counsel parents and educate developing children in a way that parallels chronologic and conceptual growth. When possible, the child should be involved in an age-appropriate fashion in the decision-making process and accurate information about the child's history and body should be made available. In addition, parents and families need as much information as possible and support systems that will help them navigate these challenging situations.

RESUMO

Minimally invasive surgery is now standard of care for many procedures in pediatric gynecology. Laparoscopy has been well documented to produce faster recovery,decreased postoperative pain, and because of smaller incisions, a better cosmetic result. These are important when considering an active pediatric patient. Although a laparoscopic approach to endometriosis, adnexal masses, and ovarian torsion are well supported in the literature in the pediatric patient, more data are needed with regard to SILS in younger patients. Laparoscopy seems to be a better approach to oopheropexy in children undergoing radiation, and in resection of certain mullerian anomalies; however, the numbers are low.Similarly in pregnant patients, laparoscopy provides for shorter recovery times,decrease analgesic use and shorter hospital stays. Concerns about poor fetal outcomes in surgery during pregnancy for non gynecologic problems have been brought to light; however, the evidence indicates that these outcomes can be attributed to the nature of the underlying disease and not the surgical approach. With regard to pneumoperitoneum the effect of CO2 insufflation on fetal physiology and long-term outcomes remains unclear, and will continue to be an issue of controversy until larger studies are published.With both the pediatric and pregnant populations, laparoscopic complications can be diminished when performed by skilled surgeons with strict adherence to good technical principles. The advantages of laparoscopy are great, and this approach should be considered in pediatric and pregnant patients.

RESUMO

BACKGROUND: It is unclear why some adolescents experience substantial bone mineral density (BMD) loss, while others experience a minimal decrease during depot medroxyprogesterone acetate (DMPA) use. We examined biopsychosocial factors in adolescents who experienced ≥5% BMD loss from baseline compared with adolescents who experienced <5% BMD loss during DMPA use. STUDY DESIGN: A multicenter, prospective, nonrandomized study of 181 female adolescents who initiated DMPA for contraception was conducted. BMD (by dual-energy X-ray absorptiometry) and serum estradiol were measured at initiation and every 6 months for 240 weeks of DMPA use. RESULTS: Half of participants experienced BMD loss of ≥5% from baseline at the hip, and a quarter experienced BMD loss of ≥5% at the lumbar spine (BMD substantial losers, SL). Hip and lumbar spine BMD-SL received a significantly greater number of DMPA injections than non-SL (p<.001). Decreased estradiol levels did not statistically differ between BMD loss subgroups. Hip BMD-SL had significantly lower baseline body mass index (BMI) than non-SL (p=.002), and there was an inverse relationship between weight gain and degree of BMD loss. Mean calcium intake was significantly lower (p<.05) in hip BMD-SL, and reported alcohol use was significantly higher (p<.05) in lumbar spine BMD-SL compared with non-SL. CONCLUSIONS: BMD loss of ≥5% was more common at the hip than at the lumbar spine among adolescents using DMPA. Decreased serum estradiol levels did not correlate with magnitude of BMD loss. Lower BMI and calcium intake and greater alcohol use were associated with greater BMD loss in adolescents using DMPA.

RESUMO

BACKGROUND: Depot medroxyprogesterone acetate (DMPA) is a highly effective progestin-only contraceptive that is widely used by adolescents. We investigated bone mineral density (BMD) changes in female adolescents during and following use of this method. STUDY DESIGN: A multicenter, prospective, non-randomized observational study in 98 healthy female adolescents aged 12-18 years who initiated DMPA intramuscular injections for contraception and provided BMD data for up to 240 weeks while receiving DMPA and for up to 300 weeks after DMPA cessation. BMD at the lumbar spine (LS), total hip (TH) and femoral neck (FN) was assessed by dual-energy X-ray absorptiometry. A mixed model analysis of variance was used to examine BMD changes. RESULTS: At the time of their final DMPA injection, participants had mean BMD declines from baseline of 2.7% (LS), 4.1% (TH) and 3.9% (FN) (p<.001 at all three sites). Within 60 weeks of discontinuation of DMPA, mean LS BMD had returned to baseline levels, and 240 weeks after DMPA discontinuation, the mean LS BMD was 4.7% above baseline. Mean TH and FN BMD values recovered to baseline values more slowly: 240 weeks and 180 weeks, respectively, after the last DMPA injection. CONCLUSIONS: BMD loss in female adolescents receiving DMPA for contraception is substantially or fully reversible in most girls following discontinuation of DMPA, with faster recovery at the LS than at the hip.

RESUMO

PURPOSE: The purpose was twofold and included examining a bioecological model as a framework to describe social support in postpartum adolescents. The second purpose was to determine the relationship between a comprehensive view of the context of social support and symptoms of depression. DESIGN: Cross-sectional design with convenience sampling (n=85) of adolescents at 4-6 weeks postpartum, recruited from two community hospitals. METHODS: Approval was received from the university's IRB (institutional review board), each recruitment site, the adolescent mothers, and their parents or guardians. Data were collected by a research assistant during home visits using a battery of self-report instruments to measure macro, meso, and microsystems of social support. Demographics, exposure to community violence (macrosystem), social support, social network (mesosystem), and perceived stress, mastery, and self-esteem (microsystem) were predictor variables. Depressive symptoms were measured by using the Center for Epidemiologic Studies of Depression (CES-D) Scale. FINDINGS: Variables from each system were significant predictors of depressive symptoms but perceived stress was the strongest predictor. Many postpartum adolescents reported that they had been victims of violence. Significant symptoms of depression were identified in 37% of the postpartum adolescents. CONCLUSIONS: Context is important to consider in comparing international studies of social support. Researchers and clinicians should investigate variables associated with the low incidence of treatment for depressive symptoms in postpartum adolescents. CLINICAL RELEVANCE: Feelings of high self-esteem and mastery should be fostered in nursing interventions with postpartum adolescents and routine screening for symptoms of depression should be considered in relevant healthcare settings.

RESUMO

PURPOSE: During adolescence, bone formation prevails over resorption, resulting in accumulation of 40% of peak bone mass throughout this time period. Although multiple studies have explored bone mass accrual during the early stages of puberty, less is known about factors that may influence bone accrual during later years of adolescence. In the present cross-sectional study we examined relationships among bone mineral density (BMD) and demographic factors, behavioral variables, and bone metabolism markers in postmenarchal adolescent girls. METHODS: The population was comprised of 389 healthy postmenarchal adolescent girls aged 11-18 years, who were recruited into a prospective study of the effect of depot medroxyprogesterone acetate (DMPA) on bone health in adolescents. At the baseline visit, investigators collected demographic, reproductive health, and lifestyle data, and performed a complete physical examination. Body mass index (BMI) was calculated. Before study initiation, BMD at the lumbar spine, total hip, and femoral neck was measured by dual-energy X-ray absorptiometry (DXA), and markers of bone metabolism (serum bone-specific alkaline phosphatase [BAP], serum osteocalcin, and urinary N-telopeptide [uNTX]) were measured. The baseline data from this study were analyzed to evaluate possible correlates of BMD in postmenarchal adolescent girls. Potential associations between BMD values and other parameters were assessed by analysis of variance and Pearson's correlation coefficient. RESULTS: Participants enrolled in the study had a mean (+/- SD) chronological age of 14.9 +/-1.7 years (range 11-18), mean gynecologic age of 39.9 +/-23.0 months (range 1-120) postmenarche, and mean BMI of 23.5 +/-4.6 kg/m(2) (range 16.0-42.2). Racial/ethnic distribution was 46% African American, 35% Caucasian, and 19% other races; 9% had previously been pregnant. Positive correlations were observed between lumbar spine BMD and chronological age (r = .301, p < .0001), gynecologic age (r = .349, p < .0001), and BMI (r = .371, p < .0001). Total hip and femoral neck BMD values were significantly higher (p < .05 and p < .05, respectively) in African American participants compared with non-African American participants. Previous history of pregnancy was significantly associated with a lower BMD at the lumbar spine (p < .0001) and the total hip (p < .01) when compared with the BMD of adolescents who had never been pregnant. Cigarette smoking and alcohol use were not associated with significant differences in BMD. Negative correlations were observed between gynecologic age and the levels of BAP (r = -.564, p < .0001), osteocalcin (r = -.349, p < .0001), and uNTX (r = -.281, p < .0001), and between lumbar spine BMD and BAP (r = -.363, p < .0001), osteocalcin (r = -.129, p < .05), and uNTX (r = -.202, p < .001) levels. CONCLUSIONS: Our data demonstrate that chronological age, gynecologic age, race/ethnicity, BMI, and previous history of pregnancy are markedly associated with BMD in postmenarchal adolescent girls. Bone accretion in the postmenarchal years continues in the face of a slowdown in bone turnover during this time period.

RESUMO

OBJECTIVE: To compare serum müllerian-inhibiting substance (MIS) concentrations in adolescent girls with polycystic ovary syndrome (PCOS) or normal menstrual cycles. DESIGN: Prospective study. SETTING: University department of obstetrics and gynecology. PATIENT(S): Thirty-one girls (12-18 years old) with PCOS and 17 girls (12-19 years old) with normal menstrual cycles. INTERVENTION(S): Serum was collected from girls with PCOS or normal cycles during the early follicular phase of the menstrual cycle, stored frozen until assayed. MAIN OUTCOME MEASURE(S): Serum levels of MIS, E2, free-T, androstenedione, LH, and FSH. RESULT(S): Serum MIS levels in girls with PCOS were significantly higher compared with normal girls (4.1 +/- 2.2 [SD] and 2.4 +/- 1.0 ng/mL, respectively). The subjects were stratified for body mass index (BMI) (< and >25 kg/m2). Serum MIS levels in PCOS girls (4.2 +/- 3.0 ng/mL [BMI <25 kg/m2] and 4.0 +/- 1.6 [BMI >25 kg/m2]) were significantly higher compared with normal girls (2.2 +/- 0.8 and 2.6 +/- 0.7 ng/mL, respectively). CONCLUSION(S): Adolescent girls with PCOS have significantly higher serum MIS levels compared with normally cycling girls. Serum MIS levels in PCOS were not influenced by BMI. Increased MIS production may represent an early manifestation of the disease.

RESUMO

The fallopian tubes are the essential genital ducts that convey the female sex cells for fertilization. They are differentiated and detectable early in fetal life. There are numerous paratubal and tubal abnormalities that can occur at any point in the female life. Some of these are rare but may initiate significant morbidity and/or manifest as life-threatening clinical problems. A comprehensive understanding of symptoms, diagnosis, optimal imaging modalities, and medical and surgical management is vital to identify the best treatment option. The clinical entities described in this article include torsion, hydatids of Morgagni, paraovarian cysts, infections including tuboovarian abscess/pyosalpinx and salpingitis isthmic nodosa, ectopic pregnancy, tumors, and genetic disorders.
