Study Notes

Introduction to Pediatrics & Adolescent Medicine

Pediatrics is the medical specialty focusing on the physical, mental, and social well-being of children from birth to young adulthood.
Pediatric care encompasses a wide range of health services including preventive care and the diagnosis/treatment of acute & chronic diseases.

Roadmap

The course covers introductions to the syllabus, differentiating pediatric and adult patients, mortality, and ethical and legal concerns.
Communication is also a key aspect.

Subspecialties

Adolescent medicine, pediatric cardiology, child abuse pediatrics, pediatric critical care medicine, developmental-behavioral pediatrics
Pediatric emergency medicine, pediatric endocrinology
Pediatric gastroenterology-oncology, pediatric hematology-oncology
Pediatric hospital medicine, pediatric infectious diseases
Neonatal-perinatal medicine, pediatric nephrology
Pediatric pulmonology, pediatric rheumatology
Pediatric surgery, hospice and palliative medicine
Medical toxicology, sleep medicine
Sports medicine, pediatric transplant hepatology

Areas of Importance

Immunizations, full adult potential, growth & development, nutrition.
Diagnosis and treatment of disease are also areas of importance.

How Old is a Pediatric Patient?

Infants (0-2 years old)
Children (2-11 years old)
Adolescents (11-21 years old)
Neonate: (0-28 days)
Note: Age ranges vary by classification systems (AAP, others).

Adolescence Classifications

Early adolescence: 11-14 years old
Middle adolescence: 15-17 years old
Late adolescence: 18-21 years old
Note: Different classification systems use different age ranges.

Pop Quiz (Examples)

2 month old, 17 year old, 11 year old, 3 year old, 18 month old, 7 day old, 21 year old.

How is Pediatrics Different from Adult Medicine?

Patient histories, physical examinations, physiological development, prevention & safety, disease and injury, legal/ethical considerations.

The Pediatric History

Parent as primary historian, differences between parent & child histories, prenatal & birth histories, maternal/family history's, developmental history, and social history, including immunization history.

The Pediatric Physical Exam

Exam specific to age & condition, general vs focused exam, newborn, infant, toddler/child, adolescent, and physical milestones.

Examples of Physiological Differences

Body Surface Area (BSA), thinner skin, immature blood-brain barrier
Respiratory & heart rates are faster, obligate nasal breathers, smaller airways, prone to lung collapse.

Examples of Pediatric Vital Signs

Vital signs vary by age (BP, RR, HR).
The table details different age ranges with associated typical vital signs.
Note: Ranges may vary by individual.

Examples of Physiological Differences (cont'd)

Metabolism & Absorption, Tissue growth, Dehydration, Temperature control, Immune system immaturity, Water/Nutrient requirements that differ.
Immature organ systems affect medication metabolism.

Examples of Medication Pharmacokinetics

Reduced Gastro Intestinal (GI) motility, increased stomach pH; longer time to reach peak concentration, thinner moister skin, increased cutaneous perfusion.
Less muscle mass, less muscle blood flow; increased skin absorption, reduced bioavailability
Reduced metabolic enzyme activity, changing distribution, lower drug clearance, increased water volume, elevated renal clearance.
Changes in renal clearance of drugs, also noted.

Medications in Pediatrics

Smaller doses compared to adults; weight-based dosing, limited clinical trial information, medications often used "off-label."

Examples of Pediatric Lab Values

Tables provide examples of variations in ALT, U/L, creatinine clearance, bilirubin, glucose, related to different age groups. Note: Individual lab variations occur.

Developmental Differences

Development varies by age, notably egocentric thinking of children with limited resilience, limited attention span, sensory dependence, developmental windows, longer life expectancy.
Central Nervous System (CNS) development continues throughout adolescence.

Examples of Prevention and Safety Differences

Need adult assistance and protection, unique environmental exposures, placental & breastfeeding, time spent outdoors, vaccinations, exposure to media.

Examples of Disease & Injury Differences

Higher likelihood of illness or injury, some diseases child/adult-specific, younger onset may increase severity, head/neck injuries more common, fractures requiring more force, infants & children, medication metabolism differences, fewer clinical trials for children.

Common Childhood Acute Illnesses

Includes viral upper respiratory infections (URI), Respiratory Syncytial Virus (RSV), ear infections, roseola, gastroenteritis, Hand-Foot-Mouth Disease, Fifth Disease, Group A Strep, influenza, conjunctivitis, and fevers.

Common Childhood Chronic Diseases

Includes dental caries, asthma, cystic fibrosis, diabetes, obesity, overweight, malnutrition, developmental disabilities, cerebral palsy, consequences of prematurity, and mental/behavioral disorders.

What Are Vital Statistics and Why Do We Use Them?

Vital statistics are continuous data on births, deaths, marriages, and other health information.
Vital statistics include tracking locally through the states up to the national level.
Maternal and infant mortality data indicate the health status of a national population.
Vital statistics inform understanding of quality of medical care, access to care, and disparities
Also help guide public health & health policy decisions.

U.S. Infant Mortality Rate

Also includes New Mexico infant mortality rate data.
