Adolescents are a critical population that is disproportionately impacted by the HIV epidemic. More than 2 million adolescents between the age group of 10 and 19 years are living with HIV, and millions are at risk of infection. HIV risks are considerably higher among girls, especially in high-prevalence settings such as eastern and southern Africa. In addition to girls, there are other vulnerable adolescent subgroups, such as teenagers, who use intravenous (IV) drugs, gay and bisexual boys, transgender youth, male sex workers, and people who fall into more than one of these categories. Pre-exposure prophylaxis (PrEP) is a new intervention for people at high risk for acquiring HIV, with an estimated HIV incidence of >3%. Recent data from trials show evidence of the efficacy of PrEP as a powerful HIV prevention tool in high-risk populations, including men who have sex with men, HIV-1-serodiscordant heterosexual couples, and IV drug users. The reported efficacy in those trials of the daily use of oral tenofovir, alone or in combination with emtricitabine, to prevent HIV infection ranged from 44% to 75% and was heavily dependent on adherence. Despite the proven efficacy of PrEP in adult trials, concerns remain about its feasibility in real-life scenarios due to stigma, cost, and limited clinician experience with PrEP delivery. Recent studies are attempting to expand the inquiry into the efficacy of such HIV prophylaxis approaches in adolescent populations, but there are still many gaps in knowledge, and no country has yet approved it for use with adolescents. The aim of this review was to identify and summarize the evidence from studies on PrEP for adolescents. We have compiled and reviewed published studies focusing on safety, feasibility, adherence to therapeutics, self-perception, and legal issues related to PrEP in people aged between 10 and 24 years.

Systemic juvenile idiopathic arthritis (SJIA) is a disease marked with arthritis and several features of systemic inflammation including fevers, rashes, hepatosplenomegaly, lymphadenopathy, and serositis. The presentation can be variable and arthritis can be a later feature. Macrophage activation syndrome can be a life-threatening complication of this illness and requires early recognition and prompt therapy. Advancements in understanding the biology of SJIA have led to the development of cytokine-targeted therapies, mainly interleukin-1 (IL-1) and IL-6 inhibitors that have significantly improved outcomes. In this review, we provide an update on the advances in the understanding of SJIA biology and also the therapeutic options.

Background: Adolescent pregnancy is a global public health problem, particularly repeated pregnancy. The best strategy to lower prevalence of adolescent pregnancy and repeated pregnancy is promoting highly effective long-acting contraceptive methods along with special counseling programs. Long-acting reversible contraception (LARC) is the ideal contraceptive of choice for adolescents. It is not known whether immediate postpartum contraceptive counseling increases postpartum LARC use in adolescents.

Objective: To compare LARC use between immediate and conventional postpartum contraceptive counseling and discover predictive factors of postpartum LARC use.

Materials and methods: This prospective, randomized controlled trial was conducted among postpartum adolescents at Department of Obstetrics and Gynecology, Faculty of Medicine Vajira Hospital, Navamindradhiraj University, Bangkok, Thailand, from 1 July 2016 to 31 March 2017. The participants were assigned to receive immediate postpartum contraceptive counseling or conventional postpartum contraceptive counseling. The primary outcome was postpartum LARC use. The secondary outcome was predictive factors for LARC use in postpartum adolescents.

Results: Of the 233 postpartum adolescents, postpartum LARC use was 87 of 118 (73.7%) in the immediate postpartum counseling group and 49 of 115 (42.6%) in the conventional postpartum counseling group (odds ratio 3.780, 95% CI 2.18-6.57, p<0.001). A significant predictive factor for LARC use in postpartum adolescents was immediate postpartum counseling (odds ratio 3.67, 95% CI 2.10-6.41, p<0.001).

Conclusion: Immediate postpartum contraceptive counseling led to a significant increase in postpartum use of LARC in adolescents, when compared with conventional (4-6 weeks) postpartum contraceptive counseling. Adolescent mothers who received immediate postpartum counseling were 3.67 times more likely to use LARC than those who received conventional postpartum counseling.

Neoplasms of the central nervous system (CNS) are the most frequently encountered solid tumors of childhood, but are less common in adolescents and young adults (AYA), aged 15-39 years. Gliomas account for 29%-35% of the CNS tumors in AYA, with approximately two-thirds being low-grade glioma (LGG) and the remaining being high-grade glioma (HGG). We review the epidemiology, work-up, and management of LGG and HGG, focusing on the particular issues faced by the AYA population relative to pediatric and adult populations. Visual pathway glioma and brainstem glioma, which represent unique clinical entities, are only briefly discussed. As a general management approach for both LGG and HGG, maximal safe resection should be attempted. AYA with LGG who undergo gross total resection (GTR) may be safely observed. As age increases and the risk factors for recurrence accumulate, adjuvant therapy should be more strongly considered with a strong consideration of advanced radiation techniques such as proton beam therapy to reduce long-term radiation-related toxicity. Recent results also suggest survival advantage for adult patients with the use of adjuvant chemotherapy when radiation is indicated. Whenever possible, AYA patients with HGG should be enrolled in a clinical trial for the benefit of centralized genetic and molecular prognostic review and best clinical care. Chemoradiation should be offered to all World Health Organization grade IV patients with concurrent and adjuvant chemotherapy after maximal safe resection. Younger adolescents with GTR of grade III lesions may consider radiotherapy alone or sequential radiotherapy and chemotherapy if unable to tolerate concurrent treatment. A more comprehensive classification of gliomas integrating pathology and molecular data is emerging, and this integrative strategy offers the potential to be more accurate and reproducible in guiding diagnostic, prognostic, and management decisions.

Background: Adolescence is a developmentally sensitive stage, during which a medical illness may have an effect on individual development, and vice versa. Chronic medical illnesses in adolescents have been associated with psychiatric symptoms. The aim of the present register-based pilot study was to assess whether, and to what extent, different medical diagnoses predict subsequent use of mental health services among adolescents.

Methods: The study material comprised data on visits to a pediatric clinic by 12- to 16-year-old adolescent patients over a period of 5 years. Altogether, 10,154 visits by 1,781 patients were identified. The associations of the medical diagnoses with a subsequent visit to the adolescent psychiatry clinic were analyzed using logistic regression.

Results: During the follow-up period, 299 patients (16.8%) visited or contacted the adolescent psychiatry clinic at least once. Of various diagnoses, the highest odds ratios (ORs) were observed for diabetes mellitus (OR=4.07, p<0.001) and neoplasms (OR=3.29, p=0.047). An association was found between adolescent psychiatry clinic visits and female gender.

Conclusion: Medical symptoms and illnesses that require a referral to a pediatrician are a marked risk factor for later use of mental health services. The results call for screening for psychological distress among patients with somatic illnesses and prompt referrals to mental health services if required.

In this review, the epidemiology, diagnosis, and treatment of pelvic inflammatory disease (PID) are discussed from a USA perspective and the difficulties that USA adolescents face in recognizing and seeking care for PID and other sexually transmitted infections (STIs) are emphasized. Females aged 15-24 years have the highest incidence of cervical infection with Chlamydia trachomatis and Neisseria gonorrheae, the principal causes of PID. PID is common in this age group. However, the incidence of PID in the USA is not known, because it is not a reportable disease, and because clinicians vary in the criteria used for the diagnosis. The Centers for Disease Control and Prevention (CDC) recommended the following diagnostic criteria that include lower abdominal or pelvic pain and at least one of the following: adnexal tenderness or cervical motion tenderness or uterine tenderness. Because PID can have serious sequelae, the criteria emphasize sensitivity (few false-negatives) at the expense of specificity (some false-positives). Patients who have PID are usually treated in the outpatient setting, following the CDC's Guidelines for the Treatment of Sexually Transmitted Diseases 2015. They receive one dose of an intramuscular cephalosporin, together with 2 weeks of oral doxy cycline, and sometimes oral metronidazole. Improvement should usually be evident in 3 days. The USA does not offer comprehensive sex education for adolescents in public or private schools. Adolescents are unlikely to recognize the symptoms of PID and seek medical treatment. Confidentiality is important to adolescents, and low cost or free sources of confidential care are uncommon, making it unlikely that an adolescent would seek care even if she suspected an STI. The CDC has concluded that screening programs for chlamydia and gonorrhea infection help prevent PID; however, the lack of appropriate sources of care makes adolescents' participation in screening programs unlikely.

Background: Adolescent mothers are at higher risk for preeclampsia, but the effect of their age on the outcome of the pregnancy complication is not clear.

Objective: To describe maternal and neonatal outcomes among singleton adolescent pregnancies complicated with severe preeclampsia in a low-income-setting hospital and compare results according to age.

Materials and methods: Maternal and neonatal outcomes of 213 adolescent mothers complicated with severe preeclampsia delivering at the Enrique C. Sotomayor Obstetrics and Gynecology Hospital (Guayaquil, Ecuador) were analyzed and compared according to their age (16 or less years, n=82 vs 17-19 years, n=131).

Results: Cesarean section rate was high in both studied groups; otherwise, obstetrical outcome did not differ and there were no maternal deaths or severe complications. Neonatal outcome was adverse in the two groups evidenced by high rates of preterm birth, small-for-gestational-age and low-birth-weight infants, low first-minute Apgar scores and admissions to neonatal intensive care; however, it was not significantly different between the analyzed groups. There were no neonatal deaths among mothers aged 16 or less and 4 in the group aged 17-19 years. This was, however, not significant (p=0.30).

Conclusion: Pregnancy outcome in this adolescent population with severe preeclampsia was similarly adverse, independent of maternal age.

Eating disorders are serious illnesses associated with significant morbidity and mortality. Family-based treatment (FBT) has emerged as an effective intervention for adolescents with anorexia nervosa, and preliminary evidence suggests that it may be efficacious in the treatment of adolescents with bulimia nervosa. Multifamily therapy for anorexia nervosa provides a more intensive experience for families needing additional support. This review outlines the three phases of treatment, key tenets of family-based treatment, and empirical support for FBT. In addition, FBT in higher levels of care is described, as well as challenges in the implementation of FBT and recent adaptations to FBT, including offering additional support to eating-disorder caregivers. Future research is needed to identify families for whom FBT does not work, determine adaptations to FBT that may increase its efficacy, develop ways to improve treatment adherence among clinicians, and find ways to support caregivers better during treatment.

Beginning with a case vignette, a discussion follows of the reformulation of theories of gender development taking into consideration the recent upsurge of gender nonconforming and transgender youth presenting for gender services and also in the culture at large. The three predominant models of pediatric gender care are reviewed and critiqued, along with a presentation of the recently developed interdisciplinary model of gender care optimal in the treatment of gender nonconforming youth seeking either puberty blockers or cross-sex hormones.

Soft tissue sarcomas (STSs) are a heterogeneous group of tumors originating from the mesenchyme. Even though they affect individuals in all age groups, the prevalence of subtypes of STSs changes significantly from childhood through adolescence into adulthood. The mainstay of therapy is surgery, with or without the addition of chemotherapy and/or radiation therapy. These treatment modalities are associated, in many cases, with significant morbidity and, given the heterogeneity of tumor histologies encompassed by the term "STS", have not uniformly improved outcomes. Moreover, some subgroups of STSs appear to be more, and others less, responsive to conventional chemotherapy agents. Over the last two decades, our understanding of the biology of STSs is slowly increasing, allowing for the development of more targeted therapies. We review the new treatment modalities that have been tested on patients with STSs, with a special focus on adolescents and young adults, a group of patients that is often underrepresented in clinical trials and has not received the dedicated attention it deserves, given the significant differences in biology and treatment response in comparison to children and adults.
