From common childhood illnesses to rare congenital disorders, these conditions have a profound impact on the lives of young patients and their families. The field of pediatric care encompasses a wide range of specialties, including pediatric neurology, cardiology, and endocrinology, all working together to address the unique health needs of children from infancy through adolescence.

Understanding pediatric diseases is crucial to ensure proper diagnosis, treatment, and management of childhood health issues. This involves monitoring developmental milestones, conducting newborn screening, and providing comprehensive care in children’s hospitals. Pediatric specialists play a vital role in addressing concerns such as childhood obesity, asthma, and various other childhood diseases. From neonatal care to pediatric nutrition, the focus remains on promoting healthy growth and development while effectively managing acute and chronic conditions that may arise during a child’s formative years.

Common Pediatric Diseases

Pediatric diseases encompass a wide range of conditions that affect children from infancy through adolescence. These illnesses can have a significant impact on a child’s health and development, requiring specialized care and attention.

Respiratory Diseases

Respiratory diseases are particularly common in children due to their developing immune systems and smaller airways. Influenza, or the flu, is a viral infection that typically causes high fevers, muscle aches, fatigue, cough, and runny nose for five to seven days . It can be especially dangerous for young children, with complications including pneumonia and hospitalization .

The common cold, also known as an upper respiratory infection, is the primary reason children miss school . Most children experience six to eight colds per year, with symptoms including runny nose, sore throat, coughing, sneezing, and body aches .

Asthma, a potentially serious lung disease, causes coughing, chest tightness, shortness of breath, and wheezing . It’s the third-leading cause of hospitalizations among children under 15 years old .

Gastrointestinal Disorders

Gastrointestinal (GI) disorders in children can range from common to complex. These include conditions such as celiac disease, chronic constipation, inflammatory bowel disease, and various liver disorders . Pediatric gastroenterologists, hepatologists, and nutritional specialists play a crucial role in diagnosing and treating these conditions .

Some common GI disorders in children include abdominal pain, colic, gastroesophageal reflux (GERD), and food allergies . More complex conditions may involve the liver, such as biliary atresia, hepatitis, and liver tumors .

Infectious Diseases

Infectious diseases are a significant concern in pediatric care. Strep throat is common in children, with up to 3 in 10 children with a sore throat having strep throat . If left untreated, it can lead to serious complications like rheumatic fever .

Urinary tract infections (UTIs) occur when bacteria build up in the urinary tract . Proper diagnosis through a urine sample is crucial before determining treatment .

Viral infections like respiratory syncytial virus (RSV) pose a significant risk to young children. Each year in the United States, an estimated 58,000-80,000 children younger than 5 years are hospitalized due to RSV infection, with infants being among those at greatest risk .

Preventive measures, including vaccinations and good hygiene practices, play a crucial role in managing and reducing the impact of these common pediatric diseases.

Recognizing Symptoms in Children

Identifying signs of illness in children can be challenging, as symptoms may vary depending on age and specific conditions. Parents and caregivers play a crucial role in recognizing when a child might be unwell and determining whether medical attention is necessary.

Age-specific Symptoms

In infants and young children, common signs of illness include fever, sore throat, blocked or runny nose, and rashes . Parents may also notice changes in behavior, such as drowsiness, lethargy, or a decreased appetite . Older children and adolescents might exhibit different symptoms, including mood changes, declining academic performance, or loss of interest in favorite activities .

Red Flags for Serious Illness

Certain symptoms warrant immediate medical attention. These include:

1. Difficulty breathing or unusual breathing patterns
2. Pale, blotchy, or blue skin
3. Seizures or loss of consciousness
4. High fever, especially in infants under three months
5. Persistent vomiting or diarrhea
6. Severe drowsiness or unresponsiveness
7. A rash that doesn’t fade when pressed

In adolescents, additional red flags may include extreme mood changes, confused thinking, substance abuse, or ideas of suicide .

When to Seek Medical Help

Parents should trust their instincts and seek medical care if they’re concerned about their child’s health. Immediate medical attention is necessary if a child:

1. Has a fever above 38°C, especially in infants under three months
2. Shows signs of dehydration, such as decreased urination
3. Experiences persistent irritability or unusual crying
4. Has difficulty breathing or rapid breathing
5. Exhibits signs of a severe allergic reaction
6. Sustains a head injury followed by vomiting or confusion

For less urgent concerns, parents should consult a healthcare provider if symptoms persist or worsen over time. Regular check-ups and vaccinations also play a crucial role in monitoring a child’s health and preventing serious illnesses .

Diagnostic Approaches in Pediatrics

Physical Examination

Physical examination plays a crucial role in pediatric diagnostics. It involves a comprehensive assessment of the child’s health, starting from the moment they enter the examination room. The approach should be tailored to the child’s age and temperament, with the examiner displaying a friendly manner and quiet voice to facilitate cooperation .

The examination typically includes vital signs and measurements such as temperature, pulse rate, respiratory rate, blood pressure, weight, height, and head circumference. These measurements should be compared with standard growth charts and recorded as percentiles . A thorough physical examination covers various body systems, including the head, eyes, ears, nose, mouth, throat, neck, lymph nodes, spine, thorax, lungs, cardiovascular system, abdomen, genitalia, skin, and extremities .

Laboratory Tests

Laboratory tests are essential diagnostic tools in pediatric care. Common tests include:

1. Complete Blood Count (CBC): This test evaluates various blood components, helping diagnose conditions such as anemia, infections, and certain genetic disorders .
2. Blood Chemistry Panels: These assess levels of electrolytes, glucose, and markers for kidney and liver function, aiding in the diagnosis of metabolic imbalances and organ disorders .
3. Thyroid Function Tests: These evaluate the thyroid gland’s ability to produce hormones, crucial for diagnosing disorders that can impact a child’s physical and cognitive development .
4. Urinalysis: This test examines urine to detect various health issues, including kidney disorders and urinary tract infections .

Imaging Studies

Imaging studies are valuable diagnostic tools in pediatric care. The use of advanced imaging in pediatric emergency departments increased from 6.4% of encounters in 2009 to 8.7% in 2018 . However, there has been a shift in the types of imaging used:

1. Computed Tomography (CT): CT use decreased from 3.9% of encounters in 2009 to 2.9% in 2018, resulting in 27,487 fewer CT scans . This reduction is partly due to increased awareness of radiation risks associated with CT scans in children.
2. Ultrasonography: Use increased from 2.5% of encounters in 2009 to 5.8% in 2018, resulting in 92,852 more ultrasound examinations . This increase is particularly notable in diagnosing conditions like appendicitis.
3. Magnetic Resonance Imaging (MRI): MRI use doubled from 0.3% of encounters in 2009 to 0.6% in 2018 . Advances in MRI technology, including rapid protocols, have made it more feasible for use in pediatric emergency departments.
4. Nuclear Medicine Imaging: These techniques are used to evaluate various organ systems and diagnose conditions such as urinary blockages, bone cancer, and congenital hypothyroidism .

The shift towards non-radiating modalities like ultrasonography and MRI reflects efforts to minimize radiation exposure in pediatric patients while maintaining diagnostic accuracy.

Management Strategies for Pediatric Diseases

Medication Administration

Proper medication administration is crucial in pediatric care. Dosages should be determined by a child’s doctor, and liquid medications measured using syringes, medication cups, or special spoons . For infants, medications can be administered using oral syringes, squirting slowly into the side or back of the mouth . Older children may prefer tablets or capsules, which can be easier to swallow and more palatable .

Supportive Care

Supportive care aims to improve the quality of life for young cancer patients and their families . It addresses physical, emotional, and spiritual needs, including pain management, decision-making support, and end-of-life planning . Palliative care services may include specialized teams, hospice care, and psychological support . Regular mental health check-ups are important for childhood cancer survivors .

Patient and Family Education

Educating patients and families is essential for effective disease management. The American Academy of Pediatrics offers trusted pediatric patient education resources through various platforms . Families should be informed about proper medication administration techniques, potential side effects, and when to seek medical help . Education should also cover coping strategies and available support services to help families navigate the challenges of pediatric diseases .
