Pediatric Development

• Pediatrics focuses on the physical, mental, and social health of children from birth to young adulthood.
• Development is a continuous process involving physical, cognitive, emotional, and social changes.
• Growth refers to an increase in physical size, while development refers to functional capacity and skill progression.
• Normal development varies widely among children, but predictable patterns exist.
• Developmental milestones are specific achievements that children typically accomplish by a certain age.
• Gross motor skills involve large muscle movements, such as sitting, walking, and jumping.
• Fine motor skills involve small muscle movements, such as grasping, drawing, and writing.
• Language development includes understanding and using language.
• Social-emotional development involves learning to interact with others and manage emotions.
• Cognitive development involves thinking, learning, and problem-solving.
• Development can be affected by genetic factors, nutrition, environment, and healthcare.
• Healthcare providers use developmental screening tools to identify children who may be at risk for developmental delays.
• Early intervention is crucial for children with developmental delays to maximize their potential.

Pediatric Nutrition

• Adequate nutrition is essential for growth, development, and overall health in children.
• Infants require breast milk or formula as their primary source of nutrition for the first year of life.
• Breast milk provides ideal nutrition and immunologic protection for infants.
• Formula is a suitable alternative to breast milk when breastfeeding is not possible or insufficient.
• Solid foods should be introduced gradually, starting around 6 months of age.
• Common first foods include iron-fortified cereals, pureed fruits, and vegetables.
• It is important to introduce new foods one at a time to identify potential allergies.
• As children grow, their nutritional needs change.
• A balanced diet should include fruits, vegetables, grains, protein, and dairy.
• Childhood obesity is a growing concern, and prevention strategies include promoting healthy eating habits and physical activity.
• Nutritional deficiencies can lead to various health problems, such as anemia and rickets.
• Healthcare providers can provide guidance on appropriate nutrition for children of all ages.

Pediatric Infectious Diseases

• Infectious diseases are a common cause of illness in children.
• Children are more susceptible to infections due to their immature immune systems.
• Common childhood infections include respiratory infections, gastrointestinal infections, and skin infections.
• Vaccines are an effective way to prevent many infectious diseases.
• The recommended childhood immunization schedule is based on scientific evidence.
• Antibiotics are used to treat bacterial infections, but overuse can lead to antibiotic resistance.
• Viral infections are typically treated with supportive care.
• Hand hygiene is an important measure to prevent the spread of infection.
• Respiratory Syncytial Virus (RSV) is a common cause of bronchiolitis and pneumonia in infants.
• Varicella (chickenpox) is a highly contagious viral infection that can be prevented by vaccination.
• Measles, mumps, and rubella (MMR) are vaccine-preventable viral infections that can cause serious complications.

Pediatric Respiratory Disorders

• Respiratory disorders are a common cause of morbidity in children.
• Asthma is a chronic inflammatory disease of the airways.
• Asthma symptoms include wheezing, coughing, shortness of breath, and chest tightness.
• Asthma is triggered by allergens, irritants, and respiratory infections.
• Asthma is managed with medications to control inflammation and open airways.
• Cystic fibrosis is a genetic disorder that affects the lungs and digestive system.
• Cystic fibrosis causes thick mucus to build up in the lungs, leading to chronic infections.
• Bronchiolitis is an infection of the small airways in the lungs, commonly caused by RSV.
• Pneumonia is an infection of the lungs that can be caused by bacteria, viruses, or fungi.
• Croup is an infection of the upper airway that causes a characteristic barking cough.
• Apnea is a pause in breathing that can occur in infants and children.

Pediatric Cardiovascular Disorders

• Congenital heart defects are the most common type of birth defect.
• Congenital heart defects involve abnormalities in the structure of the heart.
• Some congenital heart defects require surgical correction, while others can be managed with medication.
• Common congenital heart defects include ventricular septal defect (VSD), atrial septal defect (ASD), and tetralogy of Fallot.
• Acquired heart disease can occur as a result of infection, autoimmune disease, or other conditions.
• Kawasaki disease is an acute inflammatory illness that can affect the heart.
• Rheumatic fever is an inflammatory disease that can damage the heart valves.
• Cardiomyopathy is a disease of the heart muscle.
• Arrhythmias are irregular heartbeats.

Pediatric Gastrointestinal Disorders

• Gastrointestinal disorders are common in children.
• Vomiting and diarrhea are common symptoms of gastrointestinal illnesses.
• Dehydration is a serious complication of vomiting and diarrhea.
• Gastroenteritis is an inflammation of the stomach and intestines, often caused by a viral infection.
• Constipation is a common problem in children.
• Encopresis is fecal incontinence beyond the age of toilet training.
• Gastroesophageal reflux disease (GERD) is a condition in which stomach acid flows back into the esophagus.
• Celiac disease is an autoimmune disorder triggered by gluten.
• Inflammatory bowel disease (IBD) includes Crohn's disease and ulcerative colitis.

Pediatric Neurologic Disorders

• Neurologic disorders can affect the brain, spinal cord, and nerves.
• Seizures are caused by abnormal electrical activity in the brain.
• Epilepsy is a chronic seizure disorder.
• Cerebral palsy is a group of disorders that affect muscle movement and coordination.
• Spina bifida is a birth defect that occurs when the spinal cord does not close completely during pregnancy.
• Hydrocephalus is a condition in which there is an excessive accumulation of cerebrospinal fluid in the brain.
• Migraines are a common type of headache in children.
• Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity.
• Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social, communication, and behavioral challenges.

Pediatric Endocrine Disorders

• Endocrine disorders affect the glands that produce hormones.
• Diabetes mellitus is a condition in which the body does not produce enough insulin or cannot use insulin effectively.
• Type 1 diabetes is an autoimmune disease in which the body attacks and destroys the insulin-producing cells in the pancreas.
• Type 2 diabetes is a condition in which the body becomes resistant to insulin.
• Hypothyroidism is a condition in which the thyroid gland does not produce enough thyroid hormone.
• Hyperthyroidism is a condition in which the thyroid gland produces too much thyroid hormone.
• Growth hormone deficiency is a condition in which the body does not produce enough growth hormone.
• Precocious puberty is the onset of puberty at an earlier than normal age.
• Adrenal insufficiency is a condition in which the adrenal glands do not produce enough cortisol.

Pediatric Renal Disorders

• Renal disorders affect the kidneys and urinary tract.
• Urinary tract infections (UTIs) are common in children.
• Vesicoureteral reflux (VUR) is a condition in which urine flows backward from the bladder into the ureters.
• Glomerulonephritis is an inflammation of the glomeruli, the filtering units of the kidneys.
• Nephrotic syndrome is a condition in which the kidneys leak protein into the urine.
• Acute kidney injury (AKI) is a sudden loss of kidney function.
• Chronic kidney disease (CKD) is a gradual loss of kidney function over time.
• Enuresis is bedwetting.

Pediatric Hematologic and Oncologic Disorders

• Hematologic disorders affect the blood and blood-forming organs.
• Anemia is a condition in which the blood does not have enough red blood cells.
• Iron deficiency anemia is the most common type of anemia in children.
• Sickle cell disease is a genetic disorder that affects red blood cells.
• Hemophilia is a genetic disorder that affects blood clotting.
• Leukemia is a cancer of the blood and bone marrow.
• Lymphoma is a cancer of the lymphatic system.
• Brain tumors are the most common type of solid tumor in children.
• Neuroblastoma is a cancer that develops from immature nerve cells.
• Wilms tumor is a cancer of the kidney that primarily affects children.
