Presentation and Management of Uterine Didelphys with Unilateral Cervicovaginal Agenesis/Dysgenesis (CVAD): A Multicenter Case Series.

INTRODUCTION: There are several well-described presentations of uterine didelphys (UD): UD without vaginal septum, UD with non-obstructed longitudinal vaginal septum, or UD with duplicated vaginas and an obstructed hemivagina on one side with ipsilateral renal anomaly. STUDY OBJECTIVE: To describe another variant of UD and compare the presentation and management across different institutions METHODS: This was a retrospective case series approved by the NASPAG Fellows Research Consortium. Participating institutions obtained IRB approval. Inclusion criteria included a diagnosis of UD and unilateral cervicovaginal agenesis/dysgenesis (CVAD). Descriptive statistics were used. RESULTS: Five patients met the inclusion criteria, with ages ranging from 13 to 27 years. Presenting symptoms included dysmenorrhea (80%), irregular bleeding (40%), acute onset left lower quadrant pain (20%), and abdominal mass (20%). Three patients had additional known abnormalities, including solitary kidney and solitary adrenal gland. All patients underwent pelvic magnetic resonance imaging. Two cases were only suspicious for unilateral CVAD on imaging and required pathology review postoperatively to confirm diagnosis. Two cases required a 2-staged approach with an initial diagnostic surgery followed by a second definitive procedure. Three patients were noted to have endometriosis intraoperatively. Postoperative follow-up ranged from 2 months to 2 years, with 1 patient reporting chronic pelvic pain. CONCLUSION: Diagnosis on the basis of pelvic imaging can be difficult, as this unique variant may mimic classic obstructed hemivagina with ipsilateral renal anomaly. In patients with UD with unilateral CVAD, standard management is removal of the obstructed uterine horn. This multicenter series stresses awareness about the clinical presentation, distinguishes cases of cervical agenesis from dysgenesis, and reviews approaches to management.

Critical elements in the operative management of pediatric malignant ovarian germ cell tumors.

Performance of the appropriate operation is highly important to ensure that any patient with a suspected ovarian germ cell tumor receives optimal therapy that prioritizes cure while simultaneoulsy minimizing risk of short and long-term toxicities of treatment. The following critical elements of any operative procedure performed for a suspected pediatric or adolescent ovarian germ cell tumor are reviewed: 1. Complete resection of the tumor via ipsilateral oophorectomy while avoiding tumor rupture and spillage, and 2. Performance of complete intraperitoneal staging at the time of initial tumor resection.

Laparoscopic salvage procedures for adnexal torsion in pediatric and adolescent patients during the COVID-19 pandemic: a retrospective cohort study.

BACKGROUND: Early management for adnexal torsion increases likelihood of ovarian/tubal salvage. The Coronavirus disease of 2019 (COVID-19) pandemic poses delays from symptom-onset to intervention. The primary objective was to evaluate rates of ovarian salvage and tubal salvage following ovarian torsion and adnexal torsion during the COVID-19 pandemic in a pediatric and adolescent gynecology population. METHODS: This was a retrospective quality improvement cohort study of pediatric and adolescent gynecology patients at a single children's hospital who underwent laparoscopy for suspected ovarian torsion/adnexal torsion between March 2020 to March 2021. Descriptive statistics and t-tests were utilized. RESULTS: There were 50 suspected adnexal cases in 47 patients. All underwent laparoscopy, revealing 39 adnexal torsion occurrences in 36 patients and 1 patient with recurrent adnexal torsion three times. All underwent pre-operative COVID-19 testing. Mean age was 13.9 ± 2.6 years for adnexal torsion cohort. Menarche was achieved in 88% (n = 44) and 12% (n = 6) were pre-menarchal. The primary outcome was ovarian salvage and tubal salvage rates, which were 97.4% (n = 38) and 89.7% (n = 35), respectively. Secondary outcomes assessed factors contributing to the primary outcome or operative delays. The mean age of menarche was 11.2 years (salvaged) and 12.5 years (non-salvaged) (p = 0.04). There were no differences in mean pain duration or mean COVID-19 testing time between groups. Left, right and bilateral adnexal torsion occurred in 42% (n = 21), 32% (n = 16), and 4% (n = 2) respectively. The most common pathologies were paratubal cyst (n = 17, 34%) and benign ovarian cyst (n = 16, 32%). CONCLUSIONS: Ovarian salvage and tubal salvage rates were 97.4% and 89.7%, respectively during the time frame studied. These salvage rates during the study period are comparable to previous rates in a pre-COVID cohort at our institution. Institutional and departmental quality and safety initiatives likely contributed to this outcome.

NASPAG Pediatric and Adolescent Gynecology Surgery Compensation Survey.

INTRODUCTION: Over the last decade, the field of pediatric and adolescent gynecology (PAG) has rapidly expanded on the basis of a need for this specialized training to care for children and adolescents with gynecologic concerns. There are 18 PAG fellowship programs within the United States and Canada. Since 2017, which marked the beginning of the American Board of Obstetrics and Gynecology (ABOG) Focused Practice Examination in PAG and PAG Maintenance of Certification program, there has been a growing recognition of this specialty, given the unique population served. However, there is a paucity of information related to compensation in PAG. As the field has grown and more PAG fellow graduates are sought by children's hospitals throughout the United States and Canada, there is an urgent need to ensure that salary is equitable for these specialty PAG providers given the unique skills acquired during fellowship training, beyond that of obstetrics and gynecology (OBGYN) residency. This initial survey aimed to focus on compensation for PAG surgeons in the United States. OBJECTIVES: To survey NASPAG PAG surgeons in the United States about current benefits, practice metrics, and compensation METHODS: A 15-question anonymous survey was sent to PAG surgeons in the United States in February 2022, with 3 reminders sent by email to engage voluntary participation. The survey aimed to understand practice characteristics, current compensation, and relative value unit (RVU) benchmarks. Descriptive statistics were utilized. Compensation means and quartiles were calculated in U.S. dollars for the following categories: assistant professor, associate professor, and full professor. The compensation mean was also calculated for private/hybrid and instructor categories. RESULTS: Among 255 eligible members, 88 completed the survey, for a participation rate of 34.5%. Sixty-three point six percent reported having completed a PAG fellowship, whereas one-third reported specializing in this area with no fellowship available at the time. Three-fourths reported having achieved ABOG Focused Practice PAG certification. Most providers were academic (75%) and working full time (82.9%). Among academicians, most were assistant professors (48%) and on the non-tenure track (50.6%). RVU benchmarks varied, with 40.2% reporting OBGYN generalist targets and only 18.3% reporting PAG-specific targets, despite most physicians practicing only PAG (62.5%) and less than 30% practicing PAG plus some adult OBGYN. Salary support varied, with 57% employed by a hospital. Incentives were common, with most receiving a bonus at the end of the year (52.9%). As expected, full professors reported higher mean compensation ($345k) as compared with less senior colleagues ($248k and $302k for assistant and associate professors, respectively). Private practice/hybrid practitioners reported compensation ($251k) similar to that of assistant professors ($248k). Only 2 instructor-level physicians completed the survey. The mean number for this level is skewed and is not a reliable predictor for this academic level. Quartiles could not be calculated for this category. CONCLUSION: This is the first survey addressing compensation in the field of PAG in the United States. There is an ongoing need to collect this information to prepare PAG fellow graduates for the job market. Additional surveys, including an understanding of the compensation landscape in Canada, are needed in the future to address specific questions related to compensation for those who have less than 50% clinical time.

Structured Reporting in Multiple Sclerosis - Consensus-Based Reporting Templates for Magnetic Resonance Imaging of the Brain and Spinal Cord. / Strukturierte Befundung bei Multipler Sklerose ­ Konsensbasierte Befundvorlagen für die magnetresonanztomografische Untersuchung des Gehirns und des Rückenmarks.

As a result of technical developments and greater availability of imaging equipment, the number of neuroradiological examinations is steadily increasing [1]. Due to improved image quality and sensitivity, more details can be detected making reporting more complex and time-intensive. At the same time, reliable algorithms increasingly allow quantitative image analysis that should be integrated in reports in a standardized manner. Moreover, increasing digitalization is resulting in a decrease in the personal exchange between neuroradiologists and referring disciplines, thereby making communication more difficult. The introduction of structured reporting tailored to the specific disease and medical issue [2, 3] and corresponding to at least the second reporting level as defined by the German Radiological Society (https://www.befundung.drg.de/de-DE/2908/strukturierte-befundung/) is therefore desirable to ensure that the quality standards of neuroradiological reports continue to be met.The advantages of structured reporting include a reduced workload for neuroradiologists and an information gain for referring physicians. A complete and standardized list with relevant details for image reporting is provided to neuroradiologists in accordance with the current state of knowledge, thereby ensuring that important points are not forgotten [4]. A time savings and increase in efficiency during reporting were also seen [5]. Further advantages include report clarity and consistency and better comparability in follow-up examinations regardless of the neuroradiologist's particular reporting style. This results in better communication with the referring disciplines and makes clinical decision significantly easier [6, 7]. Although the advantages are significant, any potential disadvantages like the reduction of autonomy in reporting and inadequate coverage of all relevant details and any incidental findings not associated with the main pathology in complex cases or in rare diseases should be taken into consideration [4]. Therefore, studies examining the advantages of structured reporting, promoting the introduction of this system in the clinical routine, and increasing the acceptance among neuroradiologists are still needed.Numerous specific templates for structured reporting, e. g., regarding diseases in cardiology and oncology, are already available on the website www.befundung.drg.de . Multiple sclerosis (MS) is an idiopathic chronic inflammatory and neurodegenerative disease of the central nervous system and is the most common non-trauma-based inflammatory neurological disease in young adults. Therefore, it has significant individual and socioeconomic relevance [8]. Magnetic resonance imaging (MRI) plays an important role in the diagnosis, prognosis evaluation, and follow-up of this disease. MRI is established as the central diagnostic method in the diagnostic criteria. Therefore, specific changes are seen on MRI in almost all patients with a verified MS diagnosis [9]. Reporting of MRI datasets regarding the brain and spinal cord of patients with MS includes examination of the images with respect to the relevant medical issue in order to determine whether the McDonald criteria, which were revised in 2017 [10] and define dissemination in time and space clinically as well as with respect to MRI based on the recommendations of the MAGNIMS groups [11, 12], are fulfilled. A more precise definition of lesion types and locations according to the recommendations of an international expert group [13] is discussed in the supplementary material. Spinal cord signal abnormalities are seen in up to 92 % of MS patients [14-16] and are primarily located in the cervical spine [15]. The recommendations of the MAGNIMS-CMSC-NAIMS working group published in 2021 [11] explicitly recommend the use of structured reporting for MS patients.Therefore, a reporting template for evaluating MRI examinations of the brain and spinal cord of patients with MS was created as part of the BMBF-funded DIFUTURE consortium in consensus with neuroradiological and neurological experts in concordance with the recommendations mentioned above [11] and was made available for broad use (https://github.com/DRGagit/ak_befundung). The goal is to facilitate efficient and comprehensive evaluation of patients with MS in the primary diagnostic workup and follow-up imaging. These reporting templates are consensus-based recommendations and do not make any claim to general validity or completeness. The information technology working group (@GIT) of the German Radiological Society and the German Society for Neuroradiology strive to keep the reporting templates presented here up-to-date with respect to new research data and recommendations of the MAGNIMS-CMSC-NAIMS group [11]. KEY POINTS:: · consensus-based reporting templates. · template for the structured reporting of MRI examinations of patients with multiple sclerosis. · structured reporting might facilitate communication between neuroradiologists and referring disciplines.

Imperforate Hymen: Clinical Pearls and Implications of Management.

Imperforate hymen is a common condition that with classic appearance and presentation in puberty. This may be diagnosed in a neonate when mucocolpos is noted. There are many great pretenders of this condition, but the hallmarks include a bulging hymen with blue hue at puberty. If this is not seen on external genital exam, the provider should proceed with magnetic resonance imaging to better assess the reproductive tract anatomy before engaging in surgery. For providers uncomfortable in managing conditions often confused with an imperforate hymen, referral to a Pediatric and Adolescent Gynecologist or specialist comfortable managing these conditions, is recommended.

Whole-exome analysis of adolescents with low VWF and heavy menstrual bleeding identifies novel genetic associations.

Adolescents with low von Willebrand factor (VWF) levels and heavy menstrual bleeding (HMB) experience significant morbidity. There is a need to better characterize these patients genetically and improve our understanding of the pathophysiology of bleeding. We performed whole-exome sequencing on 86 postmenarchal patients diagnosed with low VWF levels (30-50 IU/dL) and HMB and compared them with 660 in-house controls. We compared the number of rare stop-gain/stop-loss and rare ClinVar "pathogenic" variants between cases and controls, as well as performed gene burden and gene-set burden analyses. We found an enrichment in cases of rare stop-gain/stop-loss variants in genes involved in bleeding disorders and an enrichment of rare ClinVar "pathogenic" variants in genes involved in anemias. The 2 most significant genes in the gene burden analysis, CFB and DNASE2, are associated with atypical hemolytic uremia and severe anemia, respectively. VWF also surpassed exome-wide significance in the gene burden analysis (P = 7.31 × 10-6). Gene-set burden analysis revealed an enrichment of rare nonsynonymous variants in cases in several hematologically relevant pathways. Further, common variants in FERMT2, a gene involved in the regulation of hemostasis and angiogenesis, surpassed genome-wide significance. We demonstrate that adolescents with HMB and low VWF have an excess of rare nonsynonymous and pathogenic variants in genes involved in bleeding disorders and anemia. Variants of variable penetrance in these genes may contribute to the spectrum of phenotypes observed in patients with HMB and could partially explain the bleeding phenotype. By identifying patients with HMB who possess these variants, we may be able to improve risk stratification and patient outcomes.

Prevalence of Polycystic Ovary Syndrome in Patients With McCune Albright Syndrome.

STUDY OBJECTIVE: To identify polycystic ovarian syndrome (PCOS) in a population of female patients with McCune-Albright syndrome (MAS) by retrospective chart review. DESIGN: Retrospective study. SETTING: Academic setting. PARTICIPANTS: All female patients with a prior diagnosis of MAS who were more than 12 years of age at the time of chart review. Only complete medical records from January 2009 to January 2020 were included in the analysis. INTERVENTIONS: None. MAIN OUTCOME MEASURE(S): Diagnosis of PCOS based on the Rotterdam 2003 criteria. RESULTS: Seventeen female patients with MAS were included in the analysis. PCOS appeared to be more prevalent in MAS patients than expected based on population estimates (exact binomial test = 0.353; CI = 0.142-0.617, P = .01). The average body mass index was not significantly different between MAS patients with and without PCOS (23.38 kg/m2 vs 23.44 kg/m2, 2-sample Wilcoxon rank-sum test with continuity correction, W = 29, P = 0.733). The majority of patients (71%) were treated with an aromatase inhibitor and/or a gonadotropin-releasing hormone (GnRH) agonist. CONCLUSIONS: The results of this study suggest that female individuals with MAS have a statistically higher prevalence of PCOS. These findings warrant further studies to determine whether the increased risk of PCOS may be associated with precocious puberty, treatment of precocious puberty, or other factors.

Imaging of Gαq Proteins in Mouse and Human Organs and Tissues.

G protein-coupled receptors (GPCRs) transfer extracellular signals across cell membranes by activating intracellular heterotrimeric G proteins. Several studies suggested G proteins as novel drug targets for the treatment of complex diseases, e.g., asthma and cancer. Recently, we developed specific radiotracers, [³H]PSB-15900-FR and [³H]PSB-16254-YM, for the Gαq family of G proteins by tritiation of the macrocyclic natural products FR900359 (FR) and YM-254890 (YM). In the present study, we utilized these potent radioligands to perform autoradiography studies in tissues of healthy mice, mouse models of disease, and human tissues. Specific binding was high, while non-specific binding was extraordinarily low, giving nearly identical results for both radioligands. High expression levels of Gαq proteins were detected in healthy mouse organs showing the following rank order of potency: kidney > liver > brain > pancreas > lung > spleen, while expression in the heart was low. Organ sub-structures, e.g., of mouse brain and lung, were clearly distinguishable. Whereas an acute asthma model in mice did not result in altered Gαq protein expressions as compared to control animals, a cutaneous melanoma model displayed significantly increased expression in comparison to healthy skin. These results suggest the future development of Gαq-protein-binding radio-tracers as novel diagnostics.

Review of Surgical Neovagina Techniques and Management of Vaginal Stricture.

STUDY OBJECTIVE: To review the currently available methods for surgical and nonsurgical neovaginal creation with an additional focus on situations requiring vaginal stretching, replacement, or augmentation and the management of vaginal stenosis or stricture. DESIGN: Review of the existing literature METHODS: PUBMED search with key words vaginal agenesis, neovaginal creation, vaginoplasty, vaginal stretching, vaginal augmentation, vaginal stenosis, outcomes of vaginoplasty, Mullerian anomalies, vaginal anomalies RESULTS: The need to perform vaginal stretching, replacement, or augmentation will vary depending on the underlying reproductive tract condition. CONCLUSIONS: A variety of techniques have been described to performed vaginal stretching, replacement, or augmentation. There are risks and benefits to each technique. Vaginal stricture and stenosis remain difficult problems given the high rates of these complications in patients undergoing these procedures. Although several techniques can alleviate this problem, they rely on the thickness of the stenosis and the location of the stenosis within the vagina.

Surgical Approach to Pediatric Ovarian Growing Teratoma Syndrome: A Case Report.

BACKGROUND: Growing teratoma syndrome is defined as conversion of a metastatic immature tumor to a mature tumor after adjuvant chemotherapy and remains an area of investigation because of its unclear pathogenesis. Because of its risk of malignant transformation, the primary treatment strategy for pediatric patients is surgical resection. CASE: In this report we present a case of a pediatric patient with recurrent growing teratoma syndrome who was treated with chemotherapy, debulking procedures, and cryoablation for the growing nodules throughout her abdominal cavity. The patient has had a good clinical outcome without recurrent malignant tumor. SUMMARY AND CONCLUSION: These masses do not always regress with chemotherapy and complete surgical excision or ablation should be attempted when possible.

The Utility of Blind Pap Tests in Young Adults with Developmental Delay: A Pilot Study.

STUDY OBJECTIVE: There are no guidelines specific to women with developmental delay who may not be able to tolerate a Papanicolaou (Pap) test in the office setting. The purpose of this study was to assess the utility of a less invasive method, a blind Pap for women with developmental delay, compared to the traditional Pap test performed in pediatric and adolescent gynecology (PAG) patients. DESIGN: Retrospective cohort pilot study. SETTING: Outpatient PAG clinics and the inpatient PAG service at a single institution. PARTICIPANTS: PAG patients who underwent a traditional Pap test and developmentally delayed PAG patients who underwent a blind Pap test. Patients were 26 years of age or less between July 2007 and March 2019. INTERVENTIONS AND MAIN OUTCOME MEASURES: Charts were reviewed to identify those who underwent a traditional Pap test (with a speculum and direct visualization) versus a blind Pap test (with a vaginal swab without a speculum). Descriptive statistics and Wilcoxon rank and Fisher exact tests compared specimen adequacy, presence of the endocervical/transformation zone (EC/TZ), and cytology results. RESULTS: Of 328 PAG patients identified, 314 patients had a traditional Pap test (control), and 14 patients had a blind Pap test (4.3%). The majority of Pap tests were satisfactory in both groups. The EC/TZ component was present in 279 (90%) specimens within the traditional Pap test group and 8 (57%) in the blind Pap test group (P = .002). The traditional Pap test group results varied, with most (81.9%) being negative for intraepithelial lesion or malignancy. All BP group pathology findings were negative for intraepithelial lesion or malignancy. CONCLUSION: Our study demonstrated an ability to perform a Pap test in a less invasive manner than a traditional Pap test. Although all blind Pap test specimens were adequate, only in 57% was the EC/TZ component reported to be present, compared to 90% of the traditional Pap test specimens.

Patterns of Genital Examination and Vulvovaginal Graft-Versus-Host Disease in a Pediatric Post-Hematopoietic Stem Cell Transplant Population.

STUDY OBJECTIVE: To determine vulvovaginal graft-versus-host disease (vvGVHD) incidence among pediatric patients who have received hematopoietic stem cell transplantation (HSCT) and who already have graft-versus-host disease (GVHD) involving any organ system and characterize patterns of genital examination and referral to pediatric and adolescent gynecology (PAG) in the post-HSCT population. DESIGN: Retrospective chart review. SETTING: Large tertiary children's hospital in Texas. PARTICIPANTS: Eighty-six post-HSCT female patients 21 years old and younger with GVHD involving any organ system. INTERVENTIONS: None. MAIN OUTCOME MEASURES: vvGVHD among post-HSCT children, referrals to PAG, genital examinations documented by any clinician. RESULTS: Eighty-six patients met inclusion criteria. Most HSCTs were bone marrow transplants, typically for leukemia. Median ages of indication diagnosis and HSCT were 5.1 and 7.5 years, respectively. Median time from HSCT to first GVHD diagnosis (eg, skin, intestine) was 96 days. Nearly all patients had at least 1 genital exam documented in the first 2 years post-HSCT, with a median of 17 exams. Twenty-eight patients were seen by PAG post-HSCT, with 7 of these patients seen within the first 2 years post-HSCT. Four symptomatic patients were diagnosed with vvGVHD. Median time from HSCT to vvGVHD was 398 days. CONCLUSION: The small number of vvGVHD cases in our study population is likely because of lack of symptom reporting from patients and families and difficulty with vvGVHD diagnosis. Further training for non-PAG physicians, including pediatricians and oncologists, in identifying and managing vvGVHD might prevent delayed diagnosis and severe sequelae. Earlier referral to PAG or a gynecologist versed in post-HSCT survivorship is also recommended.

Paratubal Cyst Recurrence in Children and Adolescents.

STUDY OBJECTIVE: To examine the association between patient characteristics and risk for recurrence risk of paratubal cysts (PTC) in children and adolescents. DESIGN: Retrospective chart review at a single institution. SETTING: Single academic children's hospital. PARTICIPANTS: Pediatric patients presenting to Texas Children's Hospital between July 2007 and March 2019. Patients were identified for the study by reviewing pathology reports and were included if they met inclusion criteria of a pathologic diagnosis of a paratubal or paraovarian cyst removed during any surgical procedure between July 2007 and March 2019. INTERVENTIONS: Subjects with pathologic diagnoses of a paratubal cyst during the study period underwent chart review for the following data points: age at presentation, ethnicity, pathologic recurrence of paratubal cysts, pubertal status, body mass index (BMI), diagnosis of polycystic ovary syndrome (PCOS), size of cyst, laterality of cysts, and number of cysts. MAIN OUTCOME MEASURE(S): Recurrence, Pathology types. RESULTS: Of the 627 patients that met inclusion criteria, the incidence of recurrence was 11.3%. Group 1 included those with recurrence of PTC (N = 70). Group 2 was identified as those without recurrence of PTC (N = 557). There were no differences related to age, BMI, ethnicity, history of PCOS, cyst size, laterality or number of cysts present. PTC NOS and serous PTC occurred most frequently. Of the unique cases involving recurrence, 70.1% recurred on the ipsilateral side. There were no cases of paratubal cyst malignancies in this cohort. The range of pathology diagnoses included pathologies that may occur in ovarian cysts. This is particularly interesting, given the known origins of ovarian cancer from fallopian tube transformations. Rare pathology diagnoses likely did not occur with frequency to determine definitive risks of recurrence in these cases. CONCLUSIONS: There appears to be a baseline recurrence risk for PTC, for which patients can be counseled. Recurrence does not appear to be associated with any particular pathology type, cyst size, number of cysts, BMI, PCOS, or puberty stage. Recurrence, should it occur, appears to occur more commonly on the ipsilateral side.

Development of a multidisciplinary colorectal and pelvic health program: Program implementation and clinical impact.

INTRODUCTION: Pediatric patients with complex colorectal and genitourinary conditions often require coordinated multidisciplinary care; however, this coordinated care can be hard to structure and deliver. The purpose of this paper is to review the development and implementation of a multidisciplinary colorectal and pelvic health program, one year after the program's initiation. METHODS: This is an observational retrospective 1-year study (10/1/2017 to 9/30/2018). In fiscal year (FY) 2018, a multidisciplinary colorectal and pelvic health program was initiated. The program development incorporated bimonthly team meetings, educational conferences, and initiation of three clinics: a complex colorectal and genitourinary reconstruction clinic, a bowel management clinic, and a colonic motility clinic. Conditions treated included complex anorectal and cloacal malformations, Hirschsprung disease, and idiopathic constipation. The fiscal year was selected to provide comparative administrative data after program implementation. RESULTS: During the study period, 121 patients underwent comprehensive collaborative evaluation of which 58 (47%) were new to the institution compared to 12 (19%) new patients in the previous year (p < 0.001). In FY 2018, there were 130 procedures performed and 512 collaborative visits with an average of 47 visits per month. This was a 3.4-fold increase in visits compared to FY2017 (171 visits). Of the new patients, 60% (35/58), traveled a median of 181 miles, representing 33 statewide counties, and 4 states compared to a median of 93 miles in the previous fiscal year (p = 0.004). CONCLUSION: The development of a colorectal and pelvic health program is feasible and requires a collaborative approach, necessitating multiple service lines within an institution. Program creation and implementation can result in rapid institutional clinical growth by filling a local and regional need through coordinated multidisciplinary care. LEVEL OF EVIDENCE: IV.

Prevention of Recurrent Mucinous Borderline Ovarian Tumor with Aromatase Inhibitor.

BACKGROUND: Aromatase inhibitors (AIs) are used for estrogen-modulated conditions. Some borderline ovarian tumors (BOT) express estrogen receptors. We present 2 cases of progression from mucinous cystadenoma to mucinous BOT (mBOT) after prior cystectomies in whom an AI was used with recurrence prevention. CASES: Two patients underwent laparoscopic ovarian cystectomy for mucinous cystadenoma. Serial imaging demonstrated recurrent ovarian cysts for which both underwent fertility sparing surgery (FSS) with ovarian cystectomy for mBOT. Both patients were initiated on an AI and have been without recurrence. SUMMARY AND CONCLUSION: BOT predominantly occur in reproductive aged females. FSS with cystectomy is an option, but recurrence occurs in 12-36% of cases. The use of AI in prevention of recurrent BOT shows promise, and more studies are needed to explore this treatment.

Physiologic Ovarian Cysts versus Other Ovarian and Adnexal Pathologic Changes in the Preadolescent and Adolescent Population: US and Surgical Follow-up.

Background Ovarian and adnexal cysts are frequently encountered at US examinations performed in preadolescent and adolescent patients, yet there are few published studies regarding the outcomes of cysts in this population. Purpose To identify characteristics at US that help to distinguish physiologic ovarian cysts from nonphysiologic entities. Materials and Methods Female patients who underwent pelvic US with or without Doppler from January 2009 through December 2013 were identified by using a centralized imaging database. Patients older than 7 years and younger than 18 years with ovarian or adnexal cysts at least 2.5 cm were included. Demographic characteristics, date of surgery, surgical notes, and pathologic reports were extracted from the electronic medical record. Initial and follow-up dates of US, cyst size and complexity, imaging diagnosis, and change on subsequent US images were recorded. Statistical analysis was performed with the Wilcoxon rank sum and Kruskal-Wallis tests for continuous variables and the Fisher exact test for categorical variables. Results Of 754 patients who met inclusion criteria (age, 8-18 years; mean age, 14.6 years ± 1.9 [standard deviation]; mean cyst size, 5 cm ± 3.3), 409 patients underwent complete follow-up that included resolution at imaging (n = 250) or surgery (n = 159). In the patients with complete imaging follow-up, mean time to US documentation of resolution was 194 days ± 321; 59.6% (149 of 250) patients had nonsimple cyst characteristics. One-hundred fifty-nine patients underwent surgical intervention (mean cyst size, 8.5 cm ± 5.3), and 69.8% (111 of 159) of the cysts had simple characteristics. Of the 159 cysts, 100 (62.8%) were defined in the pathologic report as paratubal cysts. Of 409 patients, no malignancies were encountered in this study population with surgical or imaging resolution. Conclusion No malignancies were encountered in the study population and the majority of cysts resolved at follow-up imaging. Large size, persistence, and separability from the ovary were most helpful for identification of nonphysiologic paratubal cysts. © RSNA, 2019.

Adnexal Torsion in Children and Adolescents: A Retrospective Review of 245 Cases at a Single Institution.

STUDY OBJECTIVE: Adnexal torsion (AT) requires urgent surgical intervention to preserve ovarian function. Historically, treatment for AT was oophorectomy because of concerns related to leaving a nonviable ischemic ovary. No published studies support these theoretical concerns and current literature supports conservative management. The aim of this study was to review the institutional outcomes for AT cases, including salvage rates and complications. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: This study was approved by the institutional review board at Baylor College of Medicine. A retrospective chart review on cases of AT from 2007 to 2016 at a single Children's hospital was performed on the basis of International Classification of Diseases, 10th revision and Current Procedural Terminology codes. A standardized chart review form was used in data extraction. Statistical analysis was performed using SAS version 9.4 (SAS Institute). RESULTS: Chart review identified 245 torsion cases in 237 patients. The mean age was 12.4 ± 3.29 years. Of the participants, 230 (94%) underwent minimally invasive laparoscopy with ovarian preservation in 233 (95%) of the cases. There were no complications due to detorsion of the affected adnexa. Intraoperatively, the right adnexa was affected in 134 (55%) cases and a lesion was noted in 193 (79%) cases, most commonly paratubal cysts and mature teratomas. The malignancy rate was low, noted only in 4/245 patients at (1.2%). Pediatric gynecology performed most of the cases (n = 214; 87%). CONCLUSION: The findings of our study continue to support the conservative management of patients with AT.

Can We Improve Vaginal Tissue Healing Using Customized Devices: 3D Printing and Biomechanical Changes in Vaginal Tissue.

BACKGROUND: Determining biomechanical changes in vaginal tissue with tissue stretch is critical for understanding the role of mechanotransduction on vaginal tissue healing. Noncontact dynamic optical coherence elastography (OCE) can quantify biomechanical changes in vaginal tissues noninvasively. Improved vaginal tissue healing will reduce postoperative complications from vaginal surgery. AIMS: (1) To complete dimensional assessments (DAs) of the vaginal tract. (2) To elucidate biomechanical properties (BMP) of porcine vaginal tissues (PVT). (3) Compare BMPs of piglet and adult PVTs after placement of customized vaginal dilators (VD) by OCE and uniaxial mechanical testing (MT). METHODS: Pilot study using adult nulliparous pig and piglet PVTs (n = 20 each). DA of PVTs was performed using silicone molding. 3D-printed VDs were used to achieve different Relative Diameter Change (RDC) of the PVTs (no dilatation, and -50%, 0%, 50% RDC). Elastographic testing using OCE and MT. RESULTS: Using OCE, no significant differences (SD) were noted between adult and piglet PVT (p = 0.74) or by stretch direction (p = 0.300). SD was noted with increasing RDC (p = 0.023). Using MT, there were SD in tissue stiffness between adult and piglet PVT (p = 0.048), but no SD as a function of RDC (p = 0.750) or stretch direction (p = 0.592). CONCLUSIONS: This study quantified biomechanical changes in PVT with customized stretching by 3D printed VD using both OCE and MT. This work has implications for the mechanotransduction of vaginal wound healing and noninvasive assessment of vaginal diseases.

Borderline Ovarian Tumor in the Pediatric and Adolescent Population: A Case Series and Literature Review.

STUDY OBJECTIVE: To determine the diagnosis, management, and outcome for children and adolescents with borderline ovarian tumor (BOT), and to provide a review of the literature on BOT in children and adolescents. DESIGN: A retrospective cohort study of female adolescents younger than age 21 years diagnosed with BOT between January 2001 and May 2016. SETTING: Texas Children's Hospital, Houston, Texas. PARTICIPANTS: Fourteen patients (ages 12 to 18 years) diagnosed with BOT. MAIN OUTCOME MEASURES: Clinical presentation, preoperative characteristics, surgical technique, cancer stage, histology, treatment, and recurrence. RESULTS: Median age at diagnosis was 15.5 years, with most postmenarchal. Abdominal mass/pain were the most common presenting symptoms. Median tumor size was 16.6 cm (range, 4-32 cm). Preoperative cancer antigen 125 (CA 125) was elevated in 54% (7/13) of cases. All patients had fertility-preserving surgery, either cystectomy (CY) or unilateral salpingo-oophorectomy (USO): 5 via laparoscopy (LSC) and 9 via laparotomy. Most were stage I with 5 serous and 9 mucinous BOT histology. No one received adjuvant chemotherapy. Two patients had recurrence. One had ipsilateral recurrence 2 months after LSC CY for FIGO stage IC1 mucinous BOT. The second had contralateral recurrence 15 months after laparotomy, right USO for FIGO stage IIIC serous BOT treated with LSC CY, then a second recurrence treated with USO after oocyte cryopreservation for fertility preservation. All patients were alive at last follow-up, 1 with disease. CONCLUSIONS: BOT in children and adolescents can be treated conservatively with fertility-preserving techniques and surveillance with good outcome. The role of adjuvant therapy is not known.
