Adolescent medicine Study Guide

📖 Core Concepts Adolescent medicine – specialty caring for patients from puberty onset to end of growth (roughly middle school through college graduation). Age definition – begins at puberty, ends when linear growth stops. Placement in medicine – sits within pediatrics (infancy‑adolescence) and is distinct from adult medicine; geriatrics parallels it for older adults. Key ethical pillars – confidentiality and the adolescent’s right to consent for medical care. 📌 Must Remember Health issues most commonly managed: Birth control (prescription & non‑prescription). Substance‑abuse prevention/treatment. Menstrual disorders (amenorrhea, dysmenorrhea, dysfunctional uterine bleeding). Eating disorders (anorexia, bulimia). Major mental illnesses (personality, anxiety, major depression, suicidality, bipolar, certain schizophrenia). Pubertal timing problems (delayed or precocious). LGBTQ+ youth risks: higher substance abuse, suicidality, eating disorders, unintended pregnancy, homelessness. Chronic disease impact: may delay puberty, affect growth, destabilize treatment, and create self‑management gaps (e.g., poorer diabetes control). Access barriers for marginalised youth: poor issue recognition, limited knowledge of services, structural and environmental obstacles. 🔄 Key Processes Evaluating menstrual disorder Take detailed history (onset, pain, flow). Perform pelvic exam & hormonal labs. Rule out structural causes → treat with NSAIDs, hormonal therapy, or refer. Managing an eating disorder Screen for weight, eating patterns, and psychosocial stressors. Assemble multidisciplinary team (nutritionist, dietician, mental‑health counselor, psychologist, psychiatrist). Initiate nutrition rehabilitation + psychotherapy → monitor weight & mental status. Assessing delayed/precocious puberty Obtain growth chart, bone age, hormonal profile. Involve pediatric endocrinology/urology/andrology as needed. Decide on hormone therapy or observation based on etiology. 🔍 Key Comparisons Birth control (prescription) vs. (non‑prescription) Prescription: hormonal pills, IUDs, implants – higher efficacy, require clinician oversight. Non‑prescription: condoms, emergency contraception – OTC, lower systemic effect, rely on correct use. Delayed puberty vs. Precocious puberty Delayed: onset >2 SD later than peers, may indicate chronic disease, endocrine deficiency. Precocious: onset >2 SD earlier, often central (GnRH‑dependent) or peripheral; risk of reduced adult height. ⚠️ Common Misunderstandings “Adolescents are just small adults.” – They have unique developmental, psychosocial, and physiological needs; confidentiality and consent rules differ. “All LGBTQ+ youth have the same health profile.” – Risks are higher on average, but individual variation exists; avoid stereotyping. “Medication alone fixes eating disorders.” – Multidisciplinary care is essential; neglecting mental‑health support leads to relapse. 🧠 Mental Models / Intuition “Growth‑stop = adulthood.” – When linear growth plates close, adolescent phase ends – use growth charts as a quick visual cue. “Confidentiality = trust = better care.” – Remember that preserving privacy encourages honest disclosure, especially for sexual health or mental health concerns. 🚩 Exceptions & Edge Cases Emergency contraception can be provided without parental consent even if the adolescent is a minor. Mental‑health emergencies (suicidality, psychosis) override confidentiality; clinicians must intervene and may need to breach privacy for safety. 📍 When to Use Which Choose hormonal birth control when long‑term contraception is desired and the adolescent can attend follow‑up. Opt for condoms/OTC methods for immediate, short‑term protection or when privacy concerns limit clinic visits. Refer to endocrinology for any puberty timing abnormality persisting >6 months or accompanied by growth failure. 👀 Patterns to Recognize Substance abuse + mental illness often co‑occur in LGBTQ+ youth → screen both simultaneously. Sudden drop in chronic‑disease control (e.g., HbA1c rise) may signal transition‑related self‑management lapses. Menstrual irregularities + rapid weight loss point toward eating disorder rather than primary gynecologic disease. 🗂️ Exam Traps “Adolescents cannot consent.” – Wrong; many health decisions can be made independently, respecting confidentiality. “All birth‑control methods require a prescription.” – Incorrect; condoms and emergency pills are OTC. “Precocious puberty never affects final height.” – Misleading; early epiphyseal closure can reduce adult stature. “Homelessness only affects physical health.” – Trap; it also amplifies mental‑health and substance‑use risks. --- Study tip: Review each bullet, then quiz yourself by turning the “Key Comparisons” and “Patterns to Recognize” into flashcards.
