    The current article explores some of the more complex subtopics concerning adolescents and long-acting reversible contraceptives (LARC).Recent research has highlighted ways in which LARC provision can be optimized in adolescents and has identified gaps in adolescent LARC access and utilization.Contraceptive counseling for adolescents should be patient-centered, not necessarily LARC-first, to avoid coercion. There are increasing applications for the noncontraceptive benefits of LARC for several unique patient populations and medical conditions.

  • Childhood-Onset Eosinophilic Granulomatosis with Polyangiitis with a Vulvar Granuloma: A Case Report and Review of the Literature. Journal of pediatric and adolescent gynecology Swain, C. A., Sherry, T. R., Tyson, N. 2019; 32 (4): 425?28


    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.

  • Reproductive Health: Options, Strategies, and Empowerment of Women. Obstetrics and gynecology clinics of North America Tyson, N. A. 2019; 46 (3): 409?30


    Contraception is paramount to the overall health and longevity of women. Most women in the United States use birth control in their reproductive lifetimes. All options should be available and easily accessible to permit individualization and optimization of chosen methods. Current contraceptive methods available in the United States are reviewed. Emergency contraception, contraception in the postpartum period, and strategies to tailor methods to those affected by partner violence are also addressed. Tables and flow charts help providers and patients compare various contraceptive methods, optimize the start of a method, and identify resources for addressing safety in those with underlying medical conditions.

  • Childhood and adolescent obesity definitions as related to BMI, evaluation and management options. Best practice & research. Clinical obstetrics & gynaecology Tyson, N., Frank, M. 2018; 48: 158?64


    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.

  • Committee Opinion No 672: Clinical Challenges of Long-Acting Reversible Contraceptive Methods. Obstetrics and gynecology 2016; 128 (3): e69?77


    Long-acting reversible contraceptive methods are the most effective reversible contraceptives and have an excellent safety record. Although uncommon, possible long-acting reversible contraceptive complications should be included in the informed consent process. Obstetrician-gynecologists and other gynecologic care providers should understand the diagnosis and management of common clinical challenges. The American College of Obstetricians and Gynecologists recommends the algorithms included in this document for management of the most common clinical challenges.

  • Laparoscopic Myomectomy of a Symptomatic Uterine Leiomyoma in a 15-Year-Old Adolescent. Journal of pediatric and adolescent gynecology Salehi, P. P., Tyson, N. 2016; 29 (6): e87?e90


    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.

    Obstetrician-gynecologists are responsible for promoting healthy eating and physical activity in adolescents during annual screening examinations. Adolescents with a body mass index for age greater than or equal to the 95th percentile should undergo an in-depth health assessment to determine psychosocial morbidity and risk of cardiovascular disease. Further research is needed to determine the most efficacious approach to the prevention and treatment of obesity in adolescents. For now, it is best to extrapolate an approach from data pertaining to children and adults, while being cognizant of the special psychosocial and physical needs of adolescents.
