An Atrial Septal Defect (ASD) is a congenital heart defect in which there is an abnormal opening in the interatrial septum, the wall separating the right and left atria of the heart. This defect allows oxygen-rich blood from the left atrium to flow into the right atrium, resulting in a left-to-right shunt.
This causes increased blood flow to the lungs, volume overload in the right heart, and can lead to complications such as pulmonary hypertension, arrhythmias, and heart failure if untreated.
🔹 Etiology (Causes)
✅ Congenital Causes
Most ASD cases are congenital, resulting from improper development of the atrial septum during fetal life.
Commonly associated with chromosomal abnormalities:
Down syndrome (Trisomy 21)
Holt-Oram syndrome
Noonan syndrome
✅ Genetic Mutations
Inherited mutations in cardiac developmental genes (e.g., NKX2.5, GATA4)
✅ Environmental Risk Factors in Pregnancy
Maternal infections during early pregnancy (e.g., rubella)
Exposure to teratogens (e.g., alcohol, anticonvulsants)
Poorly controlled maternal diabetes
Advanced maternal age
🔹 Types of ASD

🔹 Pathophysiology (Step-by-Step with Arrows)
📌 Normal Circulation
🔄 Oxygenated blood → Left Atrium → Left Ventricle → Aorta → Body 🔄 Deoxygenated blood → Right Atrium → Right Ventricle → Pulmonary Artery → Lungs
📉 With ASD (Left-to-Right Shunt)
1️⃣ Defect in interatrial septum develops ⬇ 2️⃣ Higher pressure in Left Atrium than Right Atrium ⬇ 3️⃣ Blood flows abnormally from Left Atrium → Right Atrium ⬇ 4️⃣ Increased volume in Right Atrium → Right Ventricle (RV) ⬇ 5️⃣ RV pumps excess blood into Pulmonary Artery ⬇ 6️⃣ Increased Pulmonary Blood Flow → Pulmonary Congestion ⬇ 7️⃣ Right heart volume overload → Right atrial and ventricular dilatation ⬇ 8️⃣ Progressive Right-sided heart strain ⬇ 9️⃣ Pulmonary Hypertension may develop ⬇ 🔟 If prolonged: Reversal of shunt (Eisenmenger syndrome) → Right-to-Left Shunt → Cyanosis
🔄 Possible Complications
Pulmonary hypertension
Right heart failure
Atrial arrhythmias (e.g., atrial fibrillation)
Paradoxical embolism (stroke risk if shunt reverses)
Monitoring, transcatheter closure, or surgical repair (depending on size/symptoms)
🔍 Clinical Manifestations
ASD symptoms depend on the size of the defect, age of the child, and the degree of shunting. Small ASDs may be asymptomatic; larger defects may lead to significant symptoms and complications.
🔹 Infants and Young Children
Often asymptomatic if the defect is small
Poor feeding or fatigue while feeding
Failure to thrive
Frequent respiratory infections
Excessive sweating
🔹 Older Children and Adolescents
Shortness of breath on exertion
Easy fatigability
Heart murmur (systolic ejection murmur at upper left sternal border)
Wide and fixed splitting of the second heart sound (S2)
Palpitations (due to atrial arrhythmias)
🔹 Adults with Untreated ASD
Atrial fibrillation or flutter
Right-sided heart failure
Pulmonary hypertension
Paradoxical embolism → risk of stroke
Clubbing and cyanosis (late complication in Eisenmenger syndrome)
💊 Medical Management
Medical management is mainly supportive, as ASDs do not close with medications. Treatment focuses on managing symptoms and preventing complications.
🔸 Observation
Small ASDs (<5 mm) may close spontaneously by age 2–4 years.
Regular follow-up with echocardiography and clinical monitoring.
🔸 Pharmacological Support
Medication
Purpose
Diuretics (e.g., Furosemide)
Reduce pulmonary congestion in symptomatic infants
Digoxin (if heart failure signs are present)
Support cardiac contractility
ACE Inhibitors (rare in ASD)
Reduce afterload and help in managing volume overload
Antiarrhythmics
Manage atrial arrhythmias in older patients
Anticoagulants
In adults with arrhythmias or embolic risk (e.g., aspirin or warfarin)
Prophylactic Antibiotics
May be indicated after surgical repair to prevent endocarditis
Medical management alone is not curative; definitive closure is often needed if the defect is moderate to large.
A Ventricular Septal Defect (VSD) is a congenital heart defect characterized by an abnormal opening in the interventricular septum, the wall separating the right and left ventricles of the heart. This opening allows oxygen-rich blood from the left ventricle to pass into the right ventricle, resulting in a left-to-right shunt.
Over time, this increased flow to the lungs can cause pulmonary hypertension, heart failure, and in severe cases, Eisenmenger syndrome (a reversal of the shunt).
🔹 Etiology (Causes)
✅ 1. Congenital Causes (Most Common)
Result from improper formation of the interventricular septum during fetal development
Often isolated or associated with syndromes such as:
Down syndrome (Trisomy 21)
DiGeorge syndrome (22q11 deletion)
Turner syndrome
Fetal alcohol syndrome
✅ 2. Genetic Mutations
Mutations in genes involved in cardiac embryogenesis (e.g., NKX2.5, TBX5)
✅ 3. Environmental Risk Factors
Maternal rubella or viral infections
Exposure to teratogenic drugs
Uncontrolled maternal diabetes
Radiation or chemical exposure during early pregnancy
✅ 4. Acquired Causes (Rare)
Trauma or myocardial infarction in adults (leading to septal rupture)
Infective endocarditis with septal involvement
🔹 Types of VSD (Based on Location)
Type

🔹 Pathophysiology (Step-by-Step with Arrows)
🔄 Normal Circulation
Oxygenated blood → Left Ventricle (LV) → Aorta → Body Deoxygenated blood → Right Ventricle (RV) → Pulmonary Artery → Lungs
📉 With VSD (Left-to-Right Shunt)
1️⃣ Defect in interventricular septum (VSD present) ⬇ 2️⃣ Higher pressure in Left Ventricle than Right Ventricle ⬇ 3️⃣ Blood flows abnormally from Left Ventricle → Right Ventricle ⬇ 4️⃣ Increased volume of blood in Right Ventricle ⬇ 5️⃣ Right Ventricle pumps excess blood into Pulmonary Artery ⬇ 6️⃣ ↑ Pulmonary blood flow → Pulmonary overcirculation ⬇ 7️⃣ Pulmonary vascular congestion and pulmonary hypertension ⬇ 8️⃣ Increased pressure in pulmonary circulation ⬇ 9️⃣ Over time: Reversal of shunt (Right-to-Left) → Cyanosis (Eisenmenger syndrome)
Presence of pulmonary hypertension or heart failure
✅ Small (Restrictive) VSD
Often asymptomatic
May be detected by a murmur during a routine check-up
Normal growth and development
High chance of spontaneous closure during infancy or early childhood
✅ Moderate to Large VSD
Infants and Children:
Poor feeding
Failure to thrive
Sweating during feeds
Tachypnea (rapid breathing) and dyspnea
Recurrent respiratory infections
Irritability or lethargy
Murmur:
Loud, harsh holosystolic murmur at lower left sternal border
Thrill may be palpable in large defects
Older children (untreated):
Exercise intolerance
Fatigue
Development of pulmonary hypertension
Risk of cyanosis (if Eisenmenger syndrome develops)
💊 Medical Management
Medical therapy is primarily supportive, used for children with moderate to large VSDs to relieve symptoms and improve nutrition until surgery is considered.
🔸 1. Observation
Small VSDs: regular monitoring with echocardiography
Many small defects close spontaneously by 2–5 years of age
🔸 2. Medical Therapy (For Symptomatic Children)
Medication
Purpose
Diuretics (e.g., Furosemide)
↓ Pulmonary congestion and preload
ACE inhibitors (e.g., Captopril)
↓ Afterload, improve left-to-right shunt control
Digoxin (in select cases)
Support cardiac function in CHF
High-calorie nutrition
For infants with failure to thrive
Iron supplements
If anemia is present (can worsen symptoms)
Medical therapy does not close the defect, but stabilizes the child while awaiting surgical closure if needed.
🛠️ Surgical Management
Surgery is indicated if:
VSD is moderate or large and causing heart failure
No spontaneous closure by 2–3 years
Child has growth failure despite medical therapy
Pulmonary hypertension is developing
There is aortic valve prolapse or regurgitation (especially in outlet VSD)
History of infective endocarditis
✅ 1. Surgical Closure (Open Heart Surgery)
Performed under general anesthesia with cardiopulmonary bypass
Approach:
Patch closure (with synthetic or pericardial patch)
Direct suture closure for small muscular VSDs
Hospital stay: 5–7 days typically
Post-op care: Monitor for arrhythmias, bleeding, or residual shunts
✅ 2. Device Closure (Transcatheter)
Indicated for select muscular VSDs
Minimally invasive, done via cardiac catheterization
Limited use in perimembranous or inlet VSDs due to proximity to valves
Auscultation: Harsh holosystolic murmur at the left lower sternal border
Signs of congestive heart failure (CHF):
Tachypnea
Diaphoresis
Hepatomegaly
Growth parameters (weight, height, head circumference)
General appearance: irritability, lethargy, cyanosis (if shunt reversal)
🔹 Nursing Diagnoses
Imbalanced nutrition: less than body requirements – related to fatigue and increased metabolic demand
Ineffective breathing pattern – related to pulmonary congestion
Activity intolerance – due to reduced oxygenation and cardiac output
Risk for infection – especially postoperatively or in failure-to-thrive children
Anxiety (parental or child) – related to unfamiliar environment or surgical intervention
Deficient knowledge – regarding condition, treatment, and home care
🔹 Nursing Interventions (Preoperative / Medical Management Phase)

Use high-calorie formula or supplements
Monitor daily weight and intake-output
For severe cases, support gavage (tube) feeding
✅ 2. Support Respiratory Function
Monitor respiratory rate, effort, and oxygen saturation
Keep child in semi-Fowler’s position to ease breathing
Provide humidified oxygen if prescribed
Administer diuretics and observe for signs of fluid overload
✅ 3. Reduce Cardiac Workload
Cluster nursing care to allow rest periods
Minimize crying (increases cardiac demand)
Monitor for tachycardia and sweating during feeding or activity
✅ 4. Prevent Infection
Practice strict hand hygiene

🔴 Patent Ductus Arteriosus (PDA)
Definition | Etiology | Pathophysiology
🔹 Definition
Patent Ductus Arteriosus (PDA) is a congenital heart defect in which the ductus arteriosus—a normal fetal blood vessel that connects the pulmonary artery to the aorta—fails to close after birth.
In the fetus, the ductus arteriosus allows blood to bypass the lungs (since the lungs are non-functional in utero).
After birth, it is supposed to close within the first few hours to days as the newborn begins to breathe air.
When it remains open (patent), it causes a left-to-right shunt of blood from the aorta into the pulmonary artery.
This leads to increased blood flow to the lungs, overloading the pulmonary circulation and left heart, potentially leading to heart failure, pulmonary hypertension, and growth failure.
🔹 Etiology (Causes)
✅ 1. Prematurity (Most Common Cause)
PDA is more common in preterm infants, especially those <28 weeks gestation.
The immature muscular layer of the ductus fails to constrict.
✅ 2. Genetic Factors
Seen in genetic syndromes such as:
Down syndrome
Rubinstein-Taybi syndrome
Char syndrome
✅ 3. Maternal Conditions
Rubella infection during the first trimester
Diabetes or poor prenatal care
✅ 4. High Altitude or Hypoxia at Birth
Hypoxic states can interfere with ductal closure
✅ 5. Congenital Heart Disease Associations
PDA may help maintain circulation in certain cyanotic heart defects (e.g., transposition of great arteries, pulmonary atresia)
🔹 Pathophysiology (Step-by-Step with Arrows)
🔄 Normal Fetal Circulation
Fetus does not use lungs for oxygen → Blood from right heart is shunted from pulmonary artery → ductus arteriosus → aorta → body ⬇ At birth → Lung expansion and oxygenation occurs → Ductus begins to constrict and close within 24–72 hours
❗If Ductus Arteriosus Remains Patent (PDA):
1️⃣ Ductus fails to close after birth ⬇ 2️⃣ Higher pressure in aorta than pulmonary artery (postnatally) ⬇ 3️⃣ Blood flows from aorta → pulmonary artery (left-to-right shunt) ⬇ 4️⃣ ↑ Pulmonary blood flow → Pulmonary overcirculation ⬇ 5️⃣ Return of excess blood to left atrium and left ventricle ⬇ 6️⃣ Volume overload in left heart → Left atrial and ventricular dilatation ⬇ 7️⃣ ↑ Workload on heart → Left-sided heart failure ⬇ 8️⃣ If untreated → Pulmonary hypertension ⬇ 9️⃣ In severe cases: Reversal of shunt (Right-to-Left) → Eisenmenger syndrome → Cyanosis
🧠 Key Physiological Consequences
Increased pulmonary circulation → risk of congestion and edema
Reduced systemic perfusion (in large PDA)
Tachycardia, poor feeding, failure to thrive
Bounding pulses and wide pulse pressure due to diastolic runoff
🔴 Patent Ductus Arteriosus (PDA)
Clinical Manifestations | Medical Management | Surgical Management
🔹 Clinical Manifestations
Symptoms depend on the size of the PDA and the amount of shunting. Small PDAs may be asymptomatic, while moderate to large PDAs can cause heart failure symptoms.
✅ General Symptoms (in Moderate to Large PDA)
Tachypnea (rapid breathing)
Labored breathing or dyspnea, especially during feeding
Continuous “machinery” murmur best heard at left upper sternal border
Left ventricular hypertrophy (on imaging or ECG)
Signs of left-sided heart failure (in severe cases)
💊 Medical Management
Medical treatment is mainly used in preterm infants or in those who are not surgical candidates. It aims to close the ductus pharmacologically or manage symptoms until surgery is possible.
✅ 1. Pharmacologic Closure (Mainly for Preterm Infants)
Use high-calorie formulas or breastmilk fortifiers
Monitor weight daily or as ordered
For infants with severe fatigue: assist with gavage (tube) feeding
✅ 2. Support Respiratory Function
Monitor respiratory rate, effort, and oxygen saturation
Position in semi-Fowler’s to ease breathing
Provide humidified oxygen as prescribed
Use suctioning (gently) to clear nasal passages
Monitor for signs of pulmonary edema
✅ 3. Reduce Cardiac Workload
Minimize crying and unnecessary handling
Cluster care to allow uninterrupted rest
Monitor heart rate, pulse quality, and capillary refill
Administer diuretics and ACE inhibitors as prescribed
✅ 4. Monitor Fluid and Electrolyte Balance
Maintain accurate intake-output charting
Restrict fluids as per physician orders (especially in heart failure)
Watch for signs of electrolyte imbalance due to diuretic use
✅ 5. Prepare for Diagnostic Procedures or Closure
Assist with and explain echocardiograms, ECGs, and lab tests
If scheduled for device closure:
Keep child NPO (nothing by mouth) pre-procedure
Monitor vital signs post-catheterization
🔹 Postoperative Nursing Care
✅ 1. Post-Transcatheter Closure
Monitor:
Heart sounds
Peripheral pulses
Vital signs
Assess puncture site (groin) for bleeding or hematoma
Encourage bed rest for prescribed time
Educate parents about:
Endocarditis prophylaxis
Activity restrictions for a few weeks
Follow-up echocardiography
✅ 2. Post-Surgical Ligation
Monitor incision site for signs of infection
Observe for hoarseness (may indicate recurrent laryngeal nerve injury)
Manage chest tube (if placed)
Administer pain relief and support early mobilization
🔹 Parental Support and Education
Explain the condition, treatment options, and recovery process
Teach signs of respiratory distress or heart failure to watch for
Reinforce medication schedule and care of surgical site (if needed)
Encourage regular follow-up appointments
Provide resources or referrals to support groups or counselors
✅ Evaluation
Goals of nursing care are achieved when:
Child shows improved feeding and weight gain
Respiratory effort is normal, with stable vitals
Child tolerates activity appropriate for age
Parents express understanding of condition and treatment
Recovery is free of infection or complications
📝 Discharge Checklist for Parents
✔️ Understand medications and dosages
✔️ Know signs of infection, heart failure, or shunt reversal
✔️ Follow-up visit scheduled with pediatric cardiologist
✔️ Clear guidance on feeding and physical activity
✔️ Awareness about endocarditis prevention (e.g., before dental procedures)
💙 Tetralogy of Fallot (TOF)
Definition | Etiology | Pathophysiology
🔹 Definition
Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart defect, comprising four anatomical abnormalities that occur together due to a single developmental defect during fetal life.
✅ The four defects are:
Ventricular Septal Defect (VSD) – a hole between the two ventricles
Pulmonary Stenosis – narrowing of the pulmonary valve or artery
Overriding Aorta – the aorta is shifted and sits above the VSD, receiving blood from both ventricles
Right Ventricular Hypertrophy – thickening of the right ventricular muscle due to increased workload
These defects result in reduced oxygenation of blood, causing cyanosis (bluish discoloration of skin and mucous membranes), especially during exertion or feeding.
🔹 Etiology (Causes)
TOF results from abnormal development of the embryonic outflow tract (conotruncus) during weeks 3–8 of gestation.
✅ 1. Genetic Causes
Sporadic in most cases
Associated with chromosomal abnormalities:
22q11 deletion syndrome (DiGeorge syndrome)
Down syndrome
Alagille syndrome
Trisomy 18 or 13
✅ 2. Maternal Risk Factors
Maternal diabetes mellitus
Alcohol or drug use during pregnancy
Poor prenatal nutrition
Maternal rubella or viral infections during early pregnancy
🔹 Pathophysiology (Step-by-Step with Arrows)
🧠 The defects interact in a way that alters normal blood flow through the heart and lungs.
🔄 Normal Circulation
Oxygen-poor blood → Right Atrium → Right Ventricle → Pulmonary Artery → Lungs Oxygen-rich blood → Left Atrium → Left Ventricle → Aorta → Body
❗ In TOF (Abnormal Circulation):
1️⃣ Pulmonary stenosis ⬇ 2️⃣ Blood from right ventricle is obstructed from flowing into pulmonary artery ⬇ 3️⃣ Pressure in right ventricle increases ⬇ 4️⃣ Blood is shunted through VSD → Left Ventricle (Right-to-Left Shunt) ⬇ 5️⃣ Aorta is overriding the septum, so it receives mixed blood (oxygenated + deoxygenated) ⬇ 6️⃣ Mixed or deoxygenated blood is pumped into the systemic circulation ⬇ 7️⃣ Results in systemic hypoxia → Cyanosis
🔁 Additional Effects:
Right ventricular hypertrophy develops due to increased resistance (from pulmonary stenosis)
During exertion, more deoxygenated blood enters systemic circulation → “Tet spells” (cyanotic episodes with rapid breathing and limpness)
🧬 Summary of Hemodynamic Changes:
Defect
Effect
VSD
Allows mixing of blood between ventricles
Pulmonary Stenosis
Reduces blood flow to lungs, raises RV pressure
Overriding Aorta
Receives blood from both ventricles (including deoxygenated)
RV Hypertrophy
Due to pressure overload from pulmonary stenosis
💙 Tetralogy of Fallot (TOF)
Clinical Manifestations | Medical Management | Surgical Management
🔹 Clinical Manifestations
Symptoms vary depending on the severity of pulmonary stenosis and the degree of right-to-left shunting.
✅ General Signs
Cyanosis (bluish discoloration of lips, nails, skin) — may be intermittent or persistent
Clubbing of fingers and toes (in older children, due to chronic hypoxia)
Poor feeding and failure to thrive
Exertional dyspnea (shortness of breath during activity)
Irritability or fatigue during feeding
Delayed growth and development
🔴 Tet Spells (Hypercyanotic Episodes)
Characteristic of TOF, typically seen in infants between 2–4 months of age.
Features of Tet Spells:
Sudden onset of deep cyanosis
Rapid breathing, fainting, or loss of consciousness
Often triggered by crying, feeding, or defecation
Knee-chest position relieves the spell (increases systemic resistance)
✅ Auscultation Findings
Harsh systolic ejection murmur (due to pulmonary stenosis) best heard at left upper sternal border
Single second heart sound (S2)
Possible thrill on palpation of the chest
💊 Medical Management
Medical therapy is supportive and used to manage symptoms or prepare the child for surgical correction.
✅ 1. During Tet Spells
Immediate interventions include:
Knee-chest position (increases systemic vascular resistance, reduces shunting)
Oxygen therapy (vasodilation of pulmonary vessels)
Morphine (calms the child, reduces respiratory effort)
Propranolol (reduces infundibular spasm of RV outflow tract)
IV fluids (to increase preload)
Sodium bicarbonate (if acidosis is present)
✅ 2. Ongoing Medical Care
Propranolol or beta-blockers: Prevent Tet spells
Iron supplementation: To prevent anemia and maintain oxygen-carrying capacity
Diuretics (if heart failure signs present)
High-calorie nutrition: For growth support
Infective endocarditis prophylaxis before dental/surgical procedures
Note: Medical management is not curative—definitive treatment is surgery.
🛠️ Surgical Management
Surgery is the only definitive treatment for TOF.
✅ 1. Palliative Surgery
Used in young infants (<3–6 months) who are not yet candidates for complete repair (e.g., small pulmonary arteries, poor weight).
🔸 Modified Blalock–Taussig Shunt (MBTS)
A Gore-Tex tube graft is placed between the subclavian artery and pulmonary artery
Increases pulmonary blood flow and improves oxygenation
Temporary measure until total repair is possible
✅ 2. Total Surgical Repair (Definitive Correction)
Usually done between 6–12 months of age.
Procedure includes:
Closure of VSD with a synthetic patch
Widening of RV outflow tract and relief of pulmonary stenosis (valvotomy or transannular patch)
Realignment of the aorta (to receive blood only from the left ventricle)
🔄 Postoperative Outcomes:
Excellent prognosis with early repair
May need long-term follow-up for:
Pulmonary valve insufficiency
Arrhythmias
Right ventricular dysfunction
✅ Prognosis
Over 90% survival post-surgery with good quality of life
Early diagnosis and complete repair reduce risk of complications like:
Cyanotic spells
Polycythemia
Brain abscess
Stroke
Sudden death

❤️ Rheumatic Fever
Definition | Etiology | Pathophysiology
🔹 Definition
Rheumatic Fever (RF) is an inflammatory autoimmune disease that occurs as a delayed complication of an untreated or inadequately treated group A β-hemolytic Streptococcal (GAS) throat infection (e.g., strep pharyngitis or tonsillitis).
It primarily affects children between 5–15 years.
It can cause inflammation in multiple systems, particularly the heart, joints, skin, and brain.
The most serious consequence is Rheumatic Heart Disease (RHD), involving permanent damage to the heart valves.
⚠️ RF is a preventable cause of acquired heart disease in children, especially in developing countries.
🔹 Etiology (Cause)
✅ 1. Infectious Trigger
Caused by Group A β-hemolytic Streptococcus (Streptococcus pyogenes) infection, usually of the pharynx.
The immune system reacts not only to the bacteria but also to the body’s own tissues (molecular mimicry).
✅ 2. Predisposing Factors
Repeated or untreated strep throat infections
Poor socio-economic conditions
Overcrowding and poor access to healthcare
Genetic susceptibility (family history of RF or RHD)
🔹 Pathophysiology (Step-by-Step with Arrows)
Here’s how Rheumatic Fever develops:
1️⃣ Streptococcal throat infection (GAS pharyngitis) ⬇ 2️⃣ Immune response develops against Streptococcal antigens ⬇ 3️⃣ Cross-reactivity (molecular mimicry): Antibodies formed against bacteria mistakenly attack host tissues (heart, joints, brain, skin) ⬇ 4️⃣ Inflammatory lesions occur in connective tissues → especially in the heart, joints, brain, and skin ⬇ 5️⃣ Pancarditis (inflammation of all heart layers) may develop ⬇ 6️⃣ Endocardial inflammation → valvulitis (especially mitral and aortic valves) ⬇ 7️⃣ Healing process causes fibrosis and scarring of heart valves ⬇ 8️⃣ Results in Rheumatic Heart Disease (RHD) — permanent valve damage
🔁 Affected Organs and Features
System/Organ
Effect
Heart (Carditis)
Inflammation of endocardium, myocardium, pericardium → murmurs, heart failure
Joints
Migratory polyarthritis (large joints affected one after another)
CNS
Sydenham’s chorea (involuntary movements)
Skin
Erythema marginatum (rash), subcutaneous nodules
General
Fever, malaise, fatigue
❤️ Rheumatic Fever (RF)
Clinical Manifestations | Medical Management | Surgical Management
🔹 Clinical Manifestations
The symptoms typically appear 2–3 weeks after an episode of untreated or inadequately treated Streptococcal throat infection. The disease is diagnosed using the Revised Jones Criteria, which includes major and minor clinical signs, along with evidence of a recent strep infection.
✅ Major Manifestations (Jones Criteria)
Carditis (inflammation of the heart)
Tachycardia, new heart murmur (usually mitral or aortic regurgitation)
Pericardial rub
Signs of heart failure (dyspnea, edema, fatigue)
Migratory Polyarthritis
Painful, swollen, red joints (usually large joints like knees, ankles, elbows)
Affects one joint, then moves to another
Sydenham’s Chorea
Involuntary, jerky movements of limbs and face
Emotional instability
More common in girls
Erythema Marginatum
Non-itchy, pink rings on the trunk and limbs
Rash may come and go
Subcutaneous Nodules
Painless, firm lumps under the skin
Found over bony prominences (e.g., elbows, knees)
✅ Minor Manifestations
Fever
Arthralgia (joint pain without swelling)
Elevated ESR or CRP
Prolonged PR interval on ECG
✅ Supporting Evidence of Streptococcal Infection
Positive throat culture or rapid antigen test for GAS
Elevated or rising ASO titer (Anti-streptolysin O)
Recent scarlet fever or pharyngitis
💊 Medical Management
🎯 Goals of Treatment
Eradicate streptococcal infection
Control inflammation and pain
Manage cardiac involvement
Prevent recurrence
✅ 1. Antibiotic Therapy
Penicillin (IM or oral) is the drug of choice
Benzathine Penicillin G IM single dose (preferred)
OR Penicillin V orally for 10 days
Erythromycin or azithromycin if allergic to penicillin
✅ 2. Anti-inflammatory Therapy
Aspirin: High doses for joint inflammation and fever
Used cautiously, monitor for bleeding and toxicity
Prednisolone (steroids): Used in moderate to severe carditis
✅ 3. Supportive Management
Bed rest during the acute phase, especially if carditis is present
Diuretics and Digoxin for heart failure
Anticonvulsants or tranquilizers (e.g., valproate or haloperidol) for severe chorea
✅ 4. Secondary Prophylaxis
To prevent recurrence of RF and RHD:
Long-acting penicillin injections (benzathine penicillin G IM) every 3–4 weeks
Duration:
Without carditis: Minimum 5 years or until age 21
With carditis but no residual heart disease: At least 10 years
With carditis and persistent valvular disease: 10 years or until age 40 (sometimes lifelong)
🛠️ Surgical Management
Surgery is not part of the acute management of RF but may be necessary if Rheumatic Heart Disease (RHD) develops due to long-term damage to heart valves.
✅ Indications for Surgery
Severe mitral or aortic valve stenosis or regurgitation
Development of heart failure not controlled by medications
Recurrent embolism due to damaged valves
✅ Surgical Options
Procedure
Indication
Valve repair (commissurotomy)
Preferred in younger patients with valve stenosis
Valve replacement (mechanical or bioprosthetic)
For severe stenosis or regurgitation
Balloon valvuloplasty (catheter-based)
Minimally invasive option in selected cases
After valve replacement, lifelong anticoagulation therapy (e.g., warfarin) is often required.
✅ Prognosis
Excellent with early diagnosis and proper treatment
Risk of recurrent attacks if prophylaxis is missed
Permanent valvular heart damage can be prevented in most cases with early antibiotic therapy
👩⚕️ Nursing Management of Rheumatic Fever
Focusing on early care, comfort, and preventing complications.
🔹 Nursing Assessment
✅ History
Recent sore throat or upper respiratory tract infection (especially untreated)
Fever, joint pain or swelling
Weakness, involuntary movements (chorea)
Family or personal history of rheumatic fever
✅ Physical Examination
Vital signs: Elevated temperature, heart rate, signs of hypotension
Observe for:
Joint swelling, redness, or tenderness (migratory polyarthritis)
Heart murmur or signs of carditis (dyspnea, fatigue, edema)
Related to: Lack of understanding about RF, its recurrence, and management Goal: Parents will verbalize understanding of disease, treatment, and prevention.

❤️ Rheumatic Heart Disease (RHD)
Definition | Etiology | Pathophysiology
🔹 Definition
Rheumatic Heart Disease (RHD) is a chronic, progressive condition resulting from permanent damage to the heart valves caused by one or more episodes of acute rheumatic fever (ARF)—an autoimmune response to Group A Streptococcal infection (usually of the throat).
Most commonly affected valve: Mitral valve
Can lead to stenosis (narrowing), regurgitation (leakage), or both
Often seen in children and young adults in low- and middle-income countries
⚠️ RHD is the most serious complication of untreated rheumatic fever and a leading cause of acquired heart disease in children.
🔹 Etiology (Causes)
✅ Primary Cause:
Repeated or severe acute rheumatic fever (ARF) following Group A β-hemolytic Streptococcal pharyngitis
✅ Predisposing Risk Factors:
Inadequate treatment of streptococcal throat infections
Recurring strep infections in childhood
Low socioeconomic conditions, overcrowding
Lack of access to preventive healthcare
Genetic susceptibility
🔹 Pathophysiology (Step-by-Step with Arrows)
Here’s a simplified step-by-step flow of how RHD develops from a strep throat infection:
1️⃣ Streptococcal pharyngitis (Group A Strep throat infection)
Obstructed blood flow (stenosis) → increases pressure in preceding chambers
Leaking valves (regurgitation) → causes volume overload and heart dilation
Ultimately leads to:
Left-sided heart failure (most common)
Arrhythmias (e.g., atrial fibrillation from left atrial enlargement)
Pulmonary hypertension
Thromboembolism or stroke
❤️ Rheumatic Heart Disease (RHD)
Clinical Manifestations | Medical Management | Surgical Management
🔹 Clinical Manifestations
Symptoms of RHD depend on the severity of valve damage, which valve is affected, and whether complications like heart failure have developed. Most commonly, the mitral valve is affected.
✅ General Symptoms:
Fatigue and weakness
Exertional dyspnea (shortness of breath on activity)
Signs of heart failure: Edema, jugular venous distention, crackles
Assess for cyanosis, activity intolerance, and nutritional status
🔹 Common Nursing Diagnoses
Nursing Diagnosis
Related to
Impaired cardiac output
Valvular insufficiency or stenosis
Activity intolerance
Fatigue, decreased oxygenation
Ineffective breathing pattern
Pulmonary congestion
Risk for infection
Invasive procedures, chronic illness
Knowledge deficit
Lack of awareness about prophylaxis and care
Risk for decreased cardiac perfusion
Valve deformities, arrhythmias
🔹 Nursing Interventions & Goals
✅ 1. Promote Optimal Cardiac Function
Goal: Maintain stable heart rate, rhythm, and perfusion
Interventions:
Monitor vital signs, heart sounds, and fluid status
Administer medications:
Diuretics (e.g., furosemide)
ACE inhibitors (e.g., enalapril)
Digoxin (if prescribed)
Elevate head of bed to reduce preload
Monitor for signs of worsening heart failure: increased weight, crackles, fatigue
Rationale: To reduce cardiac workload and manage volume overload
✅ 2. Manage Activity Intolerance
Goal: Improve energy levels and tolerance for daily activities
Interventions:
Encourage bed rest during acute phases
Schedule rest periods between activities
Promote gentle ROM exercises
Monitor response to activity (HR, SpO₂)
Rationale: Rest conserves energy and reduces oxygen demand on the heart
✅ 3. Improve Breathing and Oxygenation
Goal: Maintain clear airway and adequate gas exchange
Interventions:
Position in semi-Fowler’s or high Fowler’s
Administer oxygen therapy if indicated
Monitor for crackles, dyspnea, and SpO₂
Educate on breathing exercises
Rationale: Pulmonary congestion from left-sided heart failure impairs oxygenation
✅ 4. Administer Antibiotic Prophylaxis
Goal: Prevent recurrence of rheumatic fever and further valve damage
Interventions:
Administer IM benzathine penicillin G every 3–4 weeks as prescribed
Monitor for signs of allergic reactions
Educate family about importance of long-term prophylaxis (often for 10 years or more)
Rationale: Secondary prophylaxis prevents further streptococcal infections and recurrence
✅ 5. Provide Education and Emotional Support
Goal: Improve understanding and empower self-care
Interventions:
Explain:
Nature of RHD and importance of medication compliance
Signs of heart failure, arrhythmias, and when to seek help
Importance of regular follow-ups and echocardiograms
Need for endocarditis prophylaxis before dental/surgical procedures
Offer emotional support to child and family
Provide written medication and injection schedules
Rationale: Informed families are more likely to follow through with long-term care
✅ 6. Monitor for Complications
Goal: Detect complications early to avoid hospital readmission
Interventions:
Watch for:
New or worsening murmurs
Irregular pulses (atrial fibrillation)
Signs of embolism or stroke
Fatigue, edema, poor feeding in children
🔹 Evaluation Criteria

💓 Congestive Cardiac Failure (CCF)
Definition | Etiology | Pathophysiology
🔹 Definition
Congestive Cardiac Failure (CCF) is a clinical condition in which the heart is unable to pump sufficient blood to meet the body’s metabolic needs, either due to impaired filling (diastolic dysfunction) or pumping ability (systolic dysfunction).
It leads to fluid accumulation (congestion) in the lungs, liver, abdomen, and extremities.
Rationale: Education reduces readmission and improves outcomes.
✅ 6. Skin and Pressure Area Care
Goal: Prevent skin breakdown from edema and immobility.
Interventions:
Inspect skin daily, especially over bony prominences

✔️ Limit sodium and fluids as advised
✔️ Keep follow-up appointments and blood tests
✔️ Avoid overexertion; balance activity and rest
✔️ Know emergency signs (chest pain, severe breathlessness)
🩸 Hemophilia
Definition | Etiology
🔹 Definition
Hemophilia is a genetic bleeding disorder in which the blood lacks sufficient clotting factors, leading to delayed or prolonged bleeding. It is a lifelong condition and primarily affects males.
There are two main types:
Type
Deficient Factor
Hemophilia A
Deficiency of Factor VIII
Hemophilia B
Deficiency of Factor IX(also called Christmas disease)
In both types, the blood does not clot properly, which can result in spontaneous bleeding or prolonged bleeding after injury, surgery, or dental procedures.
🔹 Etiology (Causes)
✅ 1. Genetic Cause (Hereditary Hemophilia) – Most Common
X-linked recessive disorder:
The defective gene is carried on the X chromosome.
Males (XY) are more commonly affected because they have only one X chromosome.
Females (XX) are typically carriers and rarely show symptoms, but can pass the gene to offspring.
Inheritance Pattern:
A carrier mother has a 50% chance of passing the gene to:
Sons (who may develop hemophilia)
Daughters (who may become carriers)
✅ 2. Acquired Hemophilia (Rare)
Caused by autoimmune response where the body develops antibodies against clotting factors (usually Factor VIII).
Seen in:
Elderly
Postpartum women
People with autoimmune diseases or cancer
🔹 Pathophysiology
Hemophilia results from a deficiency or absence of specific clotting factors, which are essential in the coagulation cascade — the process by which the body forms stable blood clots to stop bleeding.
✅ Normal Clotting Cascade (Simplified)
1️⃣ Blood vessel injury ⬇ 2️⃣ Vasoconstriction occurs ⬇ 3️⃣ Platelets form a temporary plug ⬇ 4️⃣ Clotting factors (coagulation proteins) are activated in a cascade ⬇ 5️⃣ Formation of fibrin mesh → stabilizes the clot ⬇ 6️⃣ Bleeding stops
❗ In Hemophilia:
Hemophilia A = Deficiency of Factor VIII
Hemophilia B = Deficiency of Factor IX
⬇ Without these factors, the intrinsic pathway of the clotting cascade is disrupted ⬇ Inadequate fibrin clot formation ⬇ Prolonged bleeding, even from minor injuries ⬇ Spontaneous internal bleeding in joints, muscles, and organs
🔁 Compensatory Mechanisms Fail:
Platelet function is normal, so initial plug forms
But without the clotting factors, the clot is unstable
Re-bleeding is common
🔹 Clinical Manifestations
Symptoms depend on the severity of clotting factor deficiency:
Severity
Factor activity level
Bleeding tendency
Severe
<1% of normal
Spontaneous bleeding
Moderate
1–5%
Bleeding after mild trauma
Mild
5–40%
Bleeding after surgery or injury
✅ Common Signs & Symptoms
🔸 1. Prolonged Bleeding
After injury, surgery, dental procedures
Excessive bleeding from minor cuts
🔸 2. Hemarthrosis (Joint Bleeding)
Most common feature
Affects knees, elbows, ankles
Symptoms: swelling, pain, warmth, stiffness
Can lead to chronic joint deformities
🔸 3. Muscle Hematomas
Painful swelling in large muscle groups (thighs, arms)
May compress nerves or blood vessels
🔸 4. Spontaneous Bleeding
Especially in severe hemophilia
Nosebleeds, gum bleeding, or blood in urine (hematuria)
🔸 5. Intracranial Hemorrhage(life-threatening)
Headache, vomiting, altered consciousness
May occur spontaneously or after minor trauma
🔸 6. Easy Bruising
Large or unexplained bruises
🔸 In Infants and Children
Excessive bleeding after circumcision
Prolonged bleeding from teething or tongue/lip bites
Swollen joints after crawling or walking
Medical Management
🎯 Goals of Medical Management
Replace the missing clotting factor to control or prevent bleeding
Prevent joint damage and long-term complications
Educate patients and families for safe, independent living
Manage bleeding episodes promptly and preventively
🔹 1. Clotting Factor Replacement Therapy
This is the mainstay of treatment for Hemophilia A and B.
Type of Hemophilia
Deficient Factor
Replacement Therapy
Hemophilia A
Factor VIII
Recombinant or plasma-derived Factor VIII concentrate
Hemophilia B
Factor IX
Recombinant or plasma-derived Factor IX concentrate
✅ Types of Therapy:
On-demand therapy: Given when bleeding occurs
Prophylactic therapy: Regular infusions (2–3x/week) to prevent bleeding, especially in children
Recombinant products are preferred due to lower risk of infections (e.g., HIV, hepatitis).
🔹 2. Desmopressin (DDAVP)
Used only for mild Hemophilia A
Synthetic hormone that stimulates release of stored Factor VIII
Not effective in Hemophilia B
Routes: IV, SC, or intranasal
🔹 3. Antifibrinolytics
Help stabilize blood clots by preventing premature clot breakdown
Examples: Tranexamic acid, Aminocaproic acid
Useful for:
Mucosal bleeding (e.g., gums, nose)
Dental extractions
🔹 4. Management of Inhibitors (Neutralizing Antibodies)
Some patients develop antibodies against factor VIII or IX
Treatment becomes less effective or fails
Managed with:
Bypassing agents (e.g., FEIBA, rFVIIa)
Immune tolerance induction (ITI) therapy
🔹 5. Gene Therapy (Emerging)
For Hemophilia A and B (clinical trials ongoing)
Involves delivering a working gene to produce clotting factor
Potential for long-term cure or reduced treatment need
🔹 6. General Supportive Management
Pain control: Paracetamol preferred; avoid NSAIDs (aspirin, ibuprofen) as they impair platelet function
Cold compresses for superficial bleeding
Physiotherapy: To prevent joint stiffness after hemarthrosis
Vaccinations: Hepatitis A & B immunization recommended
Avoid intramuscular injections unless necessary
Careful dental hygiene to prevent gum bleeding
✅ Emergency Management of Serious Bleeding:
Immediate factor replacement
Monitor for shock in massive bleeding
CT scan for head trauma
Hospitalization if intracranial or gastrointestinal bleed is suspected
👩⚕️ Nursing Management of Hemophilia

🧬 Thalassemia
Definition | Etiology
🔹 Definition
Thalassemia is a group of inherited blood disorders characterized by abnormal or reduced production of hemoglobin, the oxygen-carrying protein in red blood cells.
It leads to chronic anemia due to the destruction of red blood cells (hemolysis) and ineffective erythropoiesis.
The severity can range from asymptomatic (mild) to life-threatening (severe).
Trait (minor), Intermedia, Major (Cooley’s anemia)
🔹 Etiology (Causes)
✅ 1. Genetic Cause
Thalassemia is caused by mutations or deletions in the genes responsible for hemoglobin production:
HBA1/HBA2 genes (for alpha chains)
HBB gene (for beta chains)
These mutations are inherited in an autosomal recessive pattern:
Carrier parents (trait) can pass the gene to children
If both parents are carriers, there’s a 25% chance the child will have thalassemia major
✅ 2. Inheritance Pattern
Autosomal recessive: both parents must pass on the defective gene
Most common in people from:
Mediterranean regions (Italy, Greece)
South and Southeast Asia
Middle East and Africa
✅ 3. Types Based on Gene Mutation:
Type
Mutation Effect
Alpha-thalassemia
Deletion of 1–4 alpha-globin genes
Beta-thalassemia
Mutation in beta-globin gene (HBB)
The more genes affected, the more severe the anemia.
🩸 Thalassemia
Pathophysiology | Clinical Manifestations
🔹 Pathophysiology
Thalassemia arises from genetic mutations that reduce or eliminate the production of one or more globin chains (α or β) required for forming normal hemoglobin (Hb).
🔁 Normal Hemoglobin Structure
Hemoglobin is made up of 4 globin chains:
2 alpha (α) chains
2 beta (β) chains
Balanced production of both chains is essential for forming stable hemoglobin (HbA).
Goal: Minimize infection risk, especially post-splenectomy.
Interventions:
Monitor temperature regularly
Maintain strict hand hygiene and aseptic technique
Ensure vaccinations are up-to-date (especially pneumococcal, meningococcal, H. influenzae)
Administer prophylactic antibiotics if prescribed
✅ 6. Provide Family and Patient Education
Goal: Improve understanding and promote long-term care adherence.
Teaching Points:
Nature of thalassemia and need for lifelong treatment
Importance of regular transfusions and chelation therapy
Signs of iron overload or complications
Dietary advice: iron-free, folic acid-rich diet
Importance of genetic counseling for family planning
Recognize signs that need emergency care (e.g., breathlessness, high fever, dark urine)
🔹 Evaluation
Nursing goals are achieved when the patient:
Maintains stable hemoglobin levels
Is free from transfusion reactions or infections
Demonstrates increased energy and improved nutrition
Complies with chelation therapy and follow-up
Family demonstrates understanding of home care, safety, and genetic counseling
📝 Discharge Teaching Checklist
✔️ Medication and transfusion schedule ✔️ Monitor for signs of iron overload ✔️ Avoid iron-rich foods and iron supplements ✔️ Importance of follow-up lab tests and clinic visits ✔️ Maintain hygiene, hydration, and nutrition ✔️ Encourage school attendance with flexibility ✔️ Use of medical alert ID for emergencies
🧒🏽🩸 Anemia in Children
Definition | Etiology | Pathophysiology
🔹 Definition
Anemia in children is a condition where there is a decrease in the number of red blood cells (RBCs) or hemoglobin (Hb) concentration below the normal age-specific levels, resulting in reduced oxygen-carrying capacity of the blood.
It leads to tissue hypoxia, which can affect growth, development, cognition, and immunity in children.
📌 Normal Hemoglobin Levels in Children:
Age Group
Normal Hemoglobin (g/dL)
Newborn
14–24
2 months
9–14
6 months to 2 years
10.5–13.5
2–6 years
11.5–13.5
6–12 years
11.5–15.5
🔹 Etiology (Causes)
Anemia in children can result from one or more of the following mechanisms:
✅ 1. Nutritional Deficiencies
Iron deficiency(most common cause)
Folic acid deficiency
Vitamin B12 deficiency
Common in rapidly growing children and those with poor diet or malabsorption.
✅ 2. Blood Loss
Acute (trauma, surgery, GI bleeding)
Chronic (hookworm infection, menstruation in adolescents)
✅ 3. Decreased RBC Production
Bone marrow suppression (aplastic anemia, chemotherapy)
Chronic infections or diseases (CKD, tuberculosis)
RBCs carry hemoglobin, which binds and transports oxygen from lungs to tissues.
When Hb or RBC count is reduced → less oxygen delivered to tissues → hypoxia
🧬 Pathophysiology Steps (Generalized):
1️⃣ Trigger or cause (e.g., iron deficiency, blood loss, hemolysis) ⬇ 2️⃣ Reduced hemoglobin production OR increased destruction/loss of RBCs ⬇ 3️⃣ Decreased number of circulating RBCs ⬇ 4️⃣ Reduced oxygen-carrying capacity of the blood ⬇ 5️⃣ Tissue hypoxia ⬇ 6️⃣ Compensatory mechanisms:
The signs and symptoms of anemia in children depend on the type, severity, and duration of the anemia. Many children may be asymptomatic in mild or slowly progressive cases.
✅ General Symptoms (All Types of Anemia)

🧒🏻🧬 Leukemia in Children
Definition | Etiology
🔹 Definition
Leukemia in children is a type of cancer of the blood and bone marrow, characterized by the uncontrolled proliferation of immature white blood cells (WBCs) called blasts. These abnormal cells crowd out healthy blood cells, leading to anemia, bleeding, and immunosuppression.
It is the most common cancer in children, accounting for about 30% of all pediatric cancers.
✅ Main Types of Childhood Leukemia:
Type
Description
Acute Lymphoblastic Leukemia (ALL)
Most common (75–80%), arises from lymphoid precursors
Acute Myeloid Leukemia (AML)
Less common (~15–20%), arises from myeloid precursors
Chronic leukemias (rare)
Chronic Myeloid Leukemia (CML) occasionally seen
🔹 Etiology (Causes)
The exact cause of leukemia in children is not fully understood, but it is believed to result from a combination of genetic mutations and environmental factors that affect blood cell development in the bone marrow.
Previous chemotherapy or radiation therapy (secondary leukemia)
Maternal smoking or alcohol use during pregnancy (possible association)
✅ 3. Immune System Factors
Children with weakened immune systems (due to congenital or acquired conditions) may have increased risk.
✅ 4. Unknown or Idiopathic
In many cases, no specific cause can be identified.
🧒🏻🧬 Leukemia in Children
Pathophysiology | Clinical Manifestations
🔹 Pathophysiology
Leukemia originates in the bone marrow, the site of blood cell production.
✅ Step-by-Step Pathophysiology:
1️⃣ A genetic mutation occurs in a single hematopoietic stem cell (often unknown cause) ⬇ 2️⃣ The cell becomes malignant and begins to multiply uncontrollably ⬇ 3️⃣ These abnormal, immature white blood cells (blasts) do not function normally ⬇ 4️⃣ Blasts accumulate in the bone marrow, crowding out healthy cells (RBCs, WBCs, platelets) ⬇ 5️⃣ Leads to:
Anemia (due to reduced RBCs)
Bleeding/bruising (due to decreased platelets)
Infections (due to non-functional WBCs and reduced normal WBCs) ⬇ 6️⃣ Blasts may infiltrate organs: liver, spleen, lymph nodes, CNS, skin, or testes ⬇ 7️⃣ Causes organomegaly, neurological symptoms, or bone pain
🔬 Differences Between ALL and AML:
Feature
ALL (Lymphoid origin)
AML (Myeloid origin)
Most common age group
2–5 years
Adolescents and infants

🔹 5. Targeted Therapy / Immunotherapy (Emerging)
For relapsed or refractory cases
Examples:
CAR-T cell therapy (Tisagenlecleucel) for B-ALL
Tyrosine kinase inhibitors (e.g., imatinib) in Ph+ ALL
✅ Monitoring and Follow-Up
Regular CBCs, bone marrow exams, and lumbar punctures
Long-term surveillance for late effects of therapy:
Growth retardation
Fertility issues
Cognitive delays
Second malignancies
✅ Prognosis
Type
Cure Rate (with treatment)
ALL
~85–90%
AML
~60–70%
Prognosis depends on age, WBC count at diagnosis, genetic markers, and response to treatment.

🧒🏻🩸 Idiopathic Thrombocytopenic Purpura (ITP) in Children
Definition | Etiology
🔹 Definition
Idiopathic Thrombocytopenic Purpura (ITP) is an autoimmune bleeding disorder in which the body’s immune system mistakenly attacks and destroys its own platelets, leading to thrombocytopenia (low platelet count) and a tendency to bleed or bruise easily.
Most commonly seen in children between 2 and 10 years, often after a viral infection.
🔍 Key Characteristics:
Sudden onset of petechiae, bruising, or mucosal bleeding
Platelet count often <100,000/mm³ (may fall below 20,000/mm³ in severe cases)
Bone marrow shows increased megakaryocytes (indicating active platelet production)
🔹 Etiology (Causes)
Although the exact cause is unknown (idiopathic), ITP is thought to be triggered by an abnormal immune response.
✅ 1. Autoimmune Mechanism
The body produces antiplatelet antibodies (usually IgG)
These antibodies bind to platelets and mark them for destruction
Platelets are destroyed prematurely in the spleen and liver
🧒🏻🩸 Idiopathic Thrombocytopenic Purpura (ITP) in Children
Pathophysiology | Clinical Manifestations
🔹 Pathophysiology
ITP is an autoimmune condition where the body produces antibodies that destroy its own platelets, leading to thrombocytopenia (low platelet count) and increased bleeding risk.
✅ Step-by-Step Pathophysiology:
1️⃣ Trigger (often a viral infection or vaccination) stimulates the immune system ⬇ 2️⃣ The immune system produces autoantibodies (IgG) against platelet surface antigens (usually GPIIb/IIIa) ⬇ 3️⃣ These antibody-coated platelets are identified as foreign ⬇ 4️⃣ Platelets are destroyed prematurely by macrophages in the spleen and liver ⬇ 5️⃣ Bone marrow increases megakaryocyte production (precursor cells of platelets) to compensate ⬇ 6️⃣ Despite increased production, the net platelet count drops due to continuous destruction ⬇ 7️⃣ Result: Impaired clot formation → easy bruising, bleeding, petechiae
🔬 Note:
Coagulation factors are normal in ITP
The bleeding is due to low platelet count, not a clotting factor defect
🔹 Clinical Manifestations
The onset is usually sudden, especially in acute ITP, and symptoms relate to bleeding due to thrombocytopenia.
✅ 1. Skin and Mucosal Bleeding
Manifestation
Description
Petechiae
Tiny red or purple pinpoint spots (non-blanching), often on legs or trunk
Purpura/Ecchymoses
Larger bruises from minor trauma or spontaneously
Bleeding gums
Especially after brushing or chewing
Epistaxis
Frequent or prolonged nosebleeds
Menorrhagia
Heavy menstrual bleeding (in adolescent girls)
✅ 2. Internal Bleeding (Rare but Serious)
Hematuria (blood in urine)
Melena (black, tarry stools)
Intracranial hemorrhage – rare but life-threatening
Encourage nutrient-rich diet to support general health
✅ 4. Reduce Anxiety and Provide Emotional Support
Goal: Child and parents feel supported and confident in care.
Interventions:
Provide age-appropriate explanation of procedures
Allow child to express fears (e.g., through play)
Support family with honest, simple communication
Involve child life specialists or counselors if needed
✅ 5. Educate Parents and Caregivers
Goal: Parents verbalize understanding of condition and home precautions.
Teaching Topics:
Avoid contact sports and activities with high injury risk
Use protective gear (helmet, knee pads) when necessary
No aspirin, NSAIDs, or herbal supplements that increase bleeding
Report:
Unexplained bruises, bleeding gums, nosebleeds
Signs of serious bleeding (e.g., vomiting blood, black stools, headache)
Follow-up appointments for labs and treatment response
Reassure that acute ITP often resolves within weeks
🔹 Evaluation
Nursing care is successful when:
Child experiences no active bleeding
Platelet count improves or stabilizes
Child remains safe and active within appropriate limits
Parents understand home care, medication, and precautions
📝 Discharge Teaching Checklist for Parents
✔️ Avoid aspirin or NSAIDs ✔️ Use soft toothbrush and no rough oral care ✔️ Prevent falls or bumps; no contact sports ✔️ Recognize and report signs of bleeding ✔️ Keep follow-up appointments and lab tests ✔️ Use medical alert ID if condition is chronic ✔️ Keep emergency contact of treating physician
🧒🏻🧬 Hodgkin’s & Non-Hodgkin’s Lymphoma in Children
Definition | Etiology
🔹 Definition
✅ Lymphoma
Lymphoma is a type of cancer of the lymphatic system, which includes the lymph nodes, spleen, thymus, and bone marrow. It involves the uncontrolled proliferation of lymphocytes (a type of white blood cell), leading to enlarged lymph nodes and organ involvement.
✅ Hodgkin’s Lymphoma (HL)
A cancer of the lymphatic system characterized by the presence of a specific cell type called the Reed–Sternberg cell.
Typically affects older children and adolescents (ages 10–19)
Usually localized initially and spreads in a predictable manner
✅ Non-Hodgkin’s Lymphoma (NHL)
A group of lymphatic cancers without Reed–Sternberg cells, often more aggressive, with widespread disease at diagnosis.
More common in younger children than Hodgkin’s
Tends to spread rapidly and unpredictably
📌 Key Differences:
Feature
Hodgkin’s Lymphoma
Non-Hodgkin’s Lymphoma
Cell type
Reed–Sternberg cells
No Reed–Sternberg cells
Age group
Adolescents, young adults
Younger children (6–12 yrs)
Growth/spread
Predictable, orderly
Rapid, widespread
Common presentation
Painless neck lymphadenopathy
Abdominal mass, chest symptoms
🔹 Etiology (Causes)
The exact cause of pediatric lymphoma is not fully known, but several risk factors and associations have been identified.
✅ 1. Genetic and Immune Factors
Inherited immunodeficiency syndromes:
Wiskott–Aldrich syndrome
Ataxia-telangiectasia
Primary immunodeficiencies (e.g., SCID)
Post-transplant immunosuppression
✅ 2. Viral Infections
Epstein–Barr Virus (EBV):
Strongly associated with Hodgkin’s lymphoma
Also linked to Burkitt lymphoma (a type of NHL)
HIV infection increases the risk of NHL
Human T-cell leukemia virus (HTLV-1)
✅ 3. Environmental and Treatment Factors
Prior chemotherapy or radiation therapy (increases future lymphoma risk)
Pesticide or toxin exposure (under investigation)
✅ 4. Genetic Mutations
Mutations affecting B-cell or T-cell development
Chromosomal translocations, especially in Burkitt lymphoma (e.g., t(8;14))
🧒🏻🧬 Hodgkin’s & Non-Hodgkin’s Lymphoma in Children
Pathophysiology | Clinical Manifestations
🔹 Pathophysiology
Both types of lymphoma originate from abnormal lymphocytes — a type of white blood cell — within the lymphatic system. However, they differ in cell origin, growth patterns, and spread.
✅ Hodgkin’s Lymphoma (HL)
1️⃣ Begins in a single lymph node region, most commonly in the cervical (neck) area ⬇ 2️⃣ Characterized by the presence of Reed–Sternberg cells (large, malignant B cells with a distinctive appearance) ⬇ 3️⃣ Triggers immune response → local inflammation and lymph node enlargement ⬇ 4️⃣ Spreads in a predictable, contiguous pattern to nearby lymph nodes ⬇ 5️⃣ May eventually involve the spleen, liver, bone marrow, or lungs
✅ Non-Hodgkin’s Lymphoma (NHL)
1️⃣ Arises from B-cells or T-cells ⬇ 2️⃣ Rapid, aggressive proliferation of abnormal lymphocytes ⬇ 3️⃣ Tends to involve multiple lymph nodes and extranodal sites (e.g., GI tract, CNS, chest) early ⬇ 4️⃣ Spreads non-contiguously (unpredictable pattern) ⬇ 5️⃣ Common subtypes in children include:
Burkitt lymphoma (B-cell)
Lymphoblastic lymphoma (T-cell)
Diffuse large B-cell lymphoma
🔹 Clinical Manifestations
✅ 1. Common Symptoms in Both Types
These are often related to lymphadenopathy and systemic effects:
System
Signs & Symptoms
Lymphatic
Painless swelling of lymph nodes (neck, axilla, groin)
Systemic (“B” symptoms)
Fever (unexplained), night sweats, weight loss (>10%)
General
Fatigue, weakness, loss of appetite
Hematologic
Anemia, leukocytosis, thrombocytopenia (in advanced cases)
✅ 2. Specific to Hodgkin’s Lymphoma
Painless, firm lymphadenopathy, especially in the neck (cervical nodes)
Lymph node enlargement is often asymmetrical and fixed
Fever of unknown origin (Pel–Ebstein fever) — intermittent fevers
Night sweats and weight loss (B symptoms — indicate more aggressive disease)
Itching (pruritus)
Alcohol-induced pain in lymph nodes (rare but classic symptom)
✅ 3. Specific to Non-Hodgkin’s Lymphoma
Rapid progression of symptoms due to aggressive growth
Abdominal mass (especially in Burkitt lymphoma):
Pain, swelling, constipation, vomiting
Mediastinal involvement (especially in T-cell lymphoma):
Importance of follow-up visits, lab tests, and medication adherence
Long-term health: fertility, growth monitoring, risk of relapse
🔹 Evaluation
Nursing care is effective when:
Child completes chemotherapy with minimal complications
No infections or bleeding episodes occur
Family follows home care instructions and attends follow-ups
Child engages in age-appropriate activities and maintains nutrition
Family demonstrates coping skills and understanding of treatment
📝 Discharge Teaching Checklist for Parents
✔️ Maintain infection precautions at home ✔️ Monitor for bleeding or unusual bruising ✔️ Ensure proper nutrition and hydration ✔️ Administer meds as directed ✔️ Keep a schedule for follow-up labs and chemotherapy ✔️ Address emotional needs and provide reassurance ✔️ Report any signs of fever, pain, vomiting, or fatigue promptly
Ebstein’s Anomaly is a rare congenital heart defect where the tricuspid valve (between the right atrium and right ventricle) is malformed and abnormally positioned (apically displaced into the right ventricle), leading to tricuspid regurgitation and right-sided heart dysfunction.
It accounts for <1% of all congenital heart defects, and severity varies widely from mild to life-threatening.
🔹 Etiology (Causes)
The exact cause is unknown, but it is believed to result from:
Abnormal development of the tricuspid valve during embryogenesis (between 5–8 weeks gestation)
May be sporadic or associated with:
Maternal lithium use during pregnancy
Genetic syndromes (e.g., Wolff-Parkinson-White syndrome, other congenital anomalies)
🔹 Pathophysiology
✅ Step-by-Step Process:
1️⃣ Tricuspid valve leaflets are displaced downward into the right ventricle ⬇ 2️⃣ Part of the right ventricle becomes “atrialized” (functions like the right atrium) ⬇ 3️⃣ Leads to tricuspid regurgitation (backflow of blood into right atrium) ⬇ 4️⃣ Causes right atrial enlargement and right-sided heart failure ⬇ 5️⃣ Decreased blood flow to lungs → cyanosis (especially in severe cases) ⬇ 6️⃣ May also have associated defects:
