Several effective contraceptive options are available for use by adolescents, including the long-acting reversible subdermal implant and intrauterine devices, which provide a high level of convenience, privacy, and effectiveness for an adolescent. Knowledge of all the effective birth control methods is essential for the pediatrician to be able to provide effective contraceptive counseling for an adolescent. An approach to counseling using a reproductive justice framework, which allows the provider and adolescent patient to engage in shared decision-making, is described. This article focuses on the long-acting reversible etonogestrel (ENG) subdermal implant for adolescents. The ENG implant is labeled for preventing pregnancy by suppressing ovulation. The ENG implant may also have a role in ameliorating dysmenorrhea and heavy menstrual bleeding. Postlabeling studies indicate that the ENG implant is effective for up to 5 years, although the device's labeling states effectivenessup to 3 years. The main contraindication to using the ENG implant is pregnancy itself. Safe initiation of the ENG implant is described, including an approach to determine whether an adolescent is pregnant. The main adverse effect of the ENG implant is an unpredictable bleeding pattern that is most often ameliorated by use of nonsteroidal anti-inflammatory medications, as well as estrogen, if not contraindicated for the patient. Details of the insertion and removal procedures, including potential complications, are described to enable the pediatrician to provide effective anticipatory guidance for the adolescent.

We describe a 15-year-old boy who presented with low back pain due to vertebral compression fractures, growth deceleration, excessive weight gain, rounded facies, dorsocervical fat pad, and hypertension. He was diagnosed as having Cushing syndrome (CS) due to primary pigmented nodular adrenocortical disease resulting in excess cortisol produced by the adrenal glands, leading to disruption of the hypothalamic-pituitary-adrenal axis. The most common cause of CS is exogenous glucocorticoids, with endogenous causes being extremely rare, often leading to delay in diagnosis or misdiagnosis. Herein, we review clinical presentation, screening for hypercortisolism, and decision-making in the diagnosis of CS, as well as therapeutic approaches. The wide range of clinical presentations in pediatric CS and the rarity of the condition can lead to difficulty in the recognition, diagnosis, and subsequent management of these patients. CS can be difficult to differentiate from more common exogenous obesity, and outpatient screening of cortisol excess is challenging. Early recognition and treatment of CS is necessary to avoid multisystemic complications, and patients with suspected endogenous CS should be referred to a tertiary care center with experienced pediatric endocrinology and surgery specialists. Further confirmatory diagnostic tests are necessary to distinguish corticotropin-independent from corticotropin-dependent forms of CS, including a high-dose dexamethasone suppression test, a corticotropin-releasing hormone stimulation test, and imaging. There can be challenges to the evaluation of CS, including complex inpatient testing and difficulty with localization on imaging. Long-term sequelae of CS, including adrenal insufficiency, obesity, hypertension, and mental health disorders, may remain despite definitive surgical treatment, meriting close follow-up with the primary care clinician and subspecialists.

Pain is a common complication of sickle cell disease. Sickle cell pain can often be effectively managed by pediatricians in outpatient and hospital settings. Acute pain management should be initiated quickly. Patients need to be evaluated for sickle cell complications and other causes of pain. Nonsteroidal anti-inflammatory drugs and opioids are the mainstay of pain treatment, but additional therapies include hydration, local pain control, muscle relaxants, and nonpharmacologic approaches. Healthy lifestyle habits and good behavioral and mental health are important for preventing and coping with sickle cell disease pain. Disease-modifying therapies, such as hydroxyurea, can help prevent sickle hemoglobin polymerization and acute pain episodes. Because sickle cell disease largely affects people who are racialized minorities in the United States, health-care providers need to be aware of how their own personal biases may affect care of these patients.
