    Reproductive cancers, encompassing various malignancies like endometrial, ovarian, cervical cancer, and gestational trophoblastic neoplasia, pose a significant global health burden. Understanding their patterns is vital for effective prevention and management. Contraceptives show a protective effect against some of these cancers. This clinical guidance document aims to elucidate the disease burden of reproductive cancers and the evidence supporting contraceptive methods in prevention and management. Regional disparities in incidence and mortality highlight the urgent need for targeted interventions, particularly in low-resource settings. Healthcare providers must weigh individual risk profiles and medical eligibility criteria when discussing contraceptive options. Enhanced health literacy through direct patient education is essential for leveraging low-cost behavioral interventions to mitigate reproductive cancer risks.

  • FIGO position statement on comprehensive sexuality education. International journal of gynaecology and obstetrics: the official organ of the International Federation of Gynaecology and Obstetrics Koch, M., Tyson, N., Bhuinneain, G. M., Kasliwal, A., Conry, J., Sridhar, A. 2024; 164 (2): 531-535


    Now is a pivotal moment in the fight for reproductive health and justice internationally. Well-established research has recognized the benefits of comprehensive sexuality education for youth and adolescents-including vast reproductive health benefits, decreased interpersonal violence, and improvements on measures of academic success and well-being. Despite these established benefits, challenges to the implementation of culturally sensitive and holistically framed sexuality education are intensifying across the globe. The International Federation of Gynecology and Obstetrics (FIGO) stands firmly in its support of comprehensive sexuality education and re-emphasizes the importance of the implementation of scientifically accurate, age-appropriate, culturally relevant, and inclusive education. Successful implementation relies on active youth leadership, physician involvement, and a renewed focus on high-quality monitoring mechanisms to assess impact and accountability at all levels. Most importantly, future efforts to improve and scale comprehensive sexuality education must emphasize the importance of an inclusive curriculum that addresses previously marginalized youth, such as LGTBQ+ and disabled individuals, through a reproductive justice lens. FIGO commits, and encourages the international healthcare community, to provide continued advocacy for the rights to health, education, and equality, in order to achieve improvement in health outcomes for young people across the globe.

  • Evaluation and Management of Endometriosis in the Adolescent. Obstetrics and gynecology Shim, J. Y., Laufer, M. R., King, C. R., Lee, T. T., Einarsson, J. I., Tyson, N. 2023


    Endometriosis is a chronic condition, with debilitating symptoms affecting all ages. Dysmenorrhea and pelvic pain often begin in adolescence, affecting school, daily activities, and relationships. Despite the profound burden of endometriosis, many adolescents experience suboptimal management and significant delay in diagnosis. The symptomatology and laparoscopic findings of endometriosis in adolescents are often different than in adults, and the medical and surgical treatments for adolescents may differ from those for adults as well. This Narrative Review summarizes the diagnosis, evaluation, and management of endometriosis in adolescents. Given the unique challenges and complexities associated with diagnosing endometriosis in this age group, it is crucial to maintain a heightened level of suspicion and to remain vigilant for signs and symptoms. By maintaining this lower threshold for consideration, we can ensure timely and accurate diagnosis, enabling early intervention and improved management in our adolescent patients.

  • Progestins of today and tomorrow. Current opinion in obstetrics & gynecology Liu, S., Kciuk, O., Frank, M., Tyson, N. 2022


    PURPOSE OF REVIEW: To review the current literature on the multiple types and uses of progestins in reproductive healthcare.RECENT FINDINGS: Progestins for contraceptive use are available in multiple forms, with the ongoing development of transdermal, intravaginal, and male contraception formulations. Noncontraceptive use of progestins often overlaps with contraceptive indications, which allows for simultaneous multipurpose progestin use, especially in reproductive-aged patients. More studies are needed to determine contraceptive doses of progestins used for noncontraceptive purposes. Side effect profiles of progestins are dependent on their formulation and cross-reactivity with other steroid receptors. Development of newer progestins includes manipulating pharmacologic properties to avoid undesired side effects.SUMMARY: Progestins have multiple uses in reproductive healthcare, including contraception, menstrual suppression, endometrial protection, and hormonal replacement therapy. The development of progestins for these indications can expand therapy for people with contraindications to estrogen-based hormonal therapy.

  • Dobbs v. Jackson Decision: It's Time to Get Uncomfortable. Hospital pediatrics Goldstein, R. L., Carlson, J. L., Tyson, N. A. 2022


    The recently announced decision of the Supreme Court in the Dobbs v. Jackson case has left health care providers, researchers, and administrators struggling to defend reproductive health care against legal restrictions. Although some hospital-based providers may not consider reproductive health care as part of their "wheelhouse," anyone who cares for adolescents and young adults must see this as a call to action. Reproductive health screening is often missed in the primary care setting1 which has led to recommendations to provide this care wherever adolescents and young adults present for care.2 As adolescents are under the legal age of majority and typically have less experience, education, and resources to help them access reproductive health care when needed, these new abortion laws will create disproportionate burdens on the adolescent population. For low-income youth and adolescent and young adults of color, this will likely worsen the disparities that already exist with regard to access to reproductive health care.3 Adolescents have the highest rates of unintended pregnancy4 and these pregnancies are more likely to end in abortion than adult pregnancies.5,6 Adolescents younger than age 20 make up 12% of individuals who have abortions in the US; minors who are 17 years or younger account for about 4% of all abortions in the US.7.

  • Subdermal Contraceptive Implant Insertion Trends and Retention in Adolescents. Journal of pediatric and adolescent gynecology Lopez, M., Merchant, M., Postlethwaite, D., Tyson, N. 2020


    PURPOSE: There is growing advocacy for use of long-acting reversible contraception among sexually active adolescents. Our primary aims were to evaluate etonogestrel subdermal contraceptive implant (SCI) insertion trends among adolescents, as well as SCI retention at 1, 2 and 3 years, indications for removal, and to identify pregnancies occurring during SCI use.METHODS: A retrospective cohort study was conducted of adolescents aged 13-19 with SCI insertions in 2008-2014 within a large integrated healthcare system. Demographic and clinical characteristics included age, race/ethnicity, BMI, gravidity, parity, insertions, reinsertions, indications for removal, and pregnancy. Electronic medical record review was conducted on a randomized sample of 540 adolescents with insertions during 2008-2011 for the retention objective to validate electronically extracted variables. Analyses included descriptive statistics, survival analysis with Kaplan-Meier estimates for implant retention and Cochran-Armitage trend test for insertions by year during 2008-2014.RESULTS: Most adolescent SCI users were non-Hispanic White (43%), or Hispanic (34.2%) and 16 years or older (84.2%) at the time of insertion. Overall, 1-, 2- and 3-year retention rates were 78.6%, 59.4% and 26.2% respectively, with retention at 44.3% at 2 years 9 months (indicative of removal of method for near expiration of 3- year device). The insertion rate trend demonstrated statistically significant increases annually, from 0.14% in 2008 to 0.91% in 2014, p< 0.0001. No pregnancies were documented during implant use. The most common indication for SCI removal was device expiration.CONCLUSIONS: SCI insertions increased annually among adolescents, with more than a six-fold increase over the 6-year study period, and over half of the SCIs retained through 2 years of use.

  • A Clinical Approach to Catamenial Epilepsy: A Review. The Permanente journal Frank, S., Tyson, N. A. 2020; 24: 1–3


    IMPORTANCE: Catamenial epilepsy (CE) is exacerbated by hormonal fluctuations during the menstrual cycle. Approximately 1.7 million women have epilepsy in the United States. CE affects more than 40% of women with epilepsy. There is a paucity of literature addressing this condition from a clinical standpoint, and the literature that does exist is limited to the neurological community. This article reviews the diagnosis and management of CE for the non-neurologist. Women with CE have early touch points in their care with numerous health care providers before ever consulting with a specialist, including OB/GYNs, pediatricians, emergency department physicians, and family medicine providers. In addition, women affected by CE have seizures that are more recalcitrant to traditional epilepsy treatment regimens. To optimize management in patients affected by CE, menstrual physiology must be understood, individualized hormonal contraception treatment considered, and adjustments and interactions with antiepileptic drugs addressed.OBSERVATIONS: CE is a unique subset of seizure disorders affected by menstrual fluctuations of progesterone and estrogen. The diagnosis of CE has been refined and clarified. There is an ever-increasing understanding of the importance and variety of options of hormonal contraception available to help manage CE. Furthermore, antiepileptic drugs and contraception can interact, so attention must be directed to optimizing both regimens to prevent uncontrolled seizures and pregnancy.CONCLUSION AND RELEVANCE: CE can be diagnosed with charting of menstrual cycles and seizure activity. Hormonal treatments that induce amenorrhea have been shown to reduce CE. Optimizing antiepileptic drug dosing and contraceptive methods also can minimize unplanned pregnancies in women affected by CE.

    Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare multisystem necrotizing vasculitis associated with eosinophilia and extravascular granuloma and classically involving the upper and lower airways. There have only been a few reported cases of gynecologic involvement in EGPA.We present an 8-year-old girl diagnosed with EGPA with a vulvar granuloma in what is, to our knowledge, the first reported pediatric gynecologic manifestation of EGPA. Interestingly, the vulvar granuloma did not respond to initial immunosuppressant treatment with prednisone and methotrexate and required treatment regimen modification with mycophenolate mofetil resulting in granuloma resolution.EGPA in the pediatric population has a relatively high mortality rate compared with in the adult population thus it is important that vulvar granulomas associated with EGPA should be included in the differential diagnosis of a vulvar mass allowing for the prompt diagnosis and treatment of this potentially fatal disease in children.

    In North America, 30% of children are overweight or obese. Child obesity is a precursor to adult health risks. Diagnosis of childhood obesity is difficult. The best measurement is BMI percentile charts. Obesity in children and adolescents can be treated by diet and activity changes. Family involvement in healthy lifestyle changes is best for weight loss and prevention.

    Although adnexal masses and ovarian torsion are common causes of acute pain in the female adolescent, fibroids are an uncommon etiology and little is reported in the literature. Because of the rarity of adolescent leiomyomas, the best surgical management is still unknown.To our knowledge, this is the first case report of a laparoscopic myomectomy in the adolescent population. The removed fibroid is one of the largest documented cases of uterine leiomyoma in adolescents.Degenerative fibroids, albeit less common, should be kept on the differential diagnosis, as a possible cause of pelvic mass and pain in the adolescent population. Fibroids in the adolescent patient, like the adult, can be managed with minimally invasive surgery with excellent clinical outcomes.
