Iron-deficiency anemia

Specialty: Pediatrics

Category: Hematologic and Oncologic Disorders

Sub-category: Hematologic Disorders

Symptoms:
fatigue; weakness; pale skin; shortness of breath; cold hands and feet; brittle nails; cravings for non-nutritive substances (pica); dizziness; headaches

Root Cause:
Caused by insufficient iron levels in the body, leading to reduced hemoglobin production and decreased oxygen-carrying capacity of red blood cells.

How it's Diagnosed: videos
Complete blood count (CBC) showing low hemoglobin and hematocrit; low serum ferritin and iron levels; increased total iron-binding capacity (TIBC); peripheral blood smear showing microcytic, hypochromic red blood cells.

Treatment:
Iron supplementation (oral or intravenous), dietary changes to include iron-rich foods (e.g., red meat, leafy greens, fortified cereals), and treating the underlying cause of iron loss (e.g., bleeding, malabsorption).

Medications:
Oral iron supplements, such as ferrous sulfate, ferrous gluconate, or ferrous fumarate, are the first-line treatment. Intravenous iron formulations, such as ferric carboxymaltose or iron sucrose, may be used in cases of severe deficiency or malabsorption.

Prevalence: How common the health condition is within a specific population.
Affects approximately 20–25% of children worldwide; more common in developing countries.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Premature birth, inadequate dietary iron intake, rapid growth during childhood, chronic blood loss (e.g., gastrointestinal bleeding), malabsorption disorders (e.g., celiac disease).

Prognosis: The expected outcome or course of the condition over time.
Excellent with appropriate treatment; symptoms typically resolve within weeks, and hemoglobin levels normalize in a few months. Untreated cases can result in developmental delays, cognitive impairment, and heart complications.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Developmental delays, cognitive and behavioral issues, weakened immune system, and heart problems like tachycardia and heart failure in severe, prolonged cases.

Sickle Cell Disease

Specialty: Pediatrics

Category: Hematologic and Oncologic Disorders

Sub-category: Hematologic Disorders

Symptoms:
episodes of pain (vaso-occlusive crisis); fatigue; swelling in hands and feet; frequent infections; delayed growth and puberty; yellowish skin or eyes (jaundice); shortness of breath

Root Cause:
Caused by a genetic mutation leading to abnormal hemoglobin (HbS), which results in red blood cells that are rigid and shaped like a crescent (sickle), leading to blockages in blood flow and reduced oxygen delivery to tissues.

How it's Diagnosed: videos
Newborn screening with hemoglobin electrophoresis; confirmatory testing includes Hb electrophoresis or DNA analysis; CBC may show anemia; peripheral blood smear reveals sickle-shaped cells.

Treatment:
Pain management, blood transfusions, hydroxyurea (to increase fetal hemoglobin), and bone marrow transplant in severe cases. Preventative care includes vaccination, prophylactic antibiotics (e.g., penicillin), and folic acid supplementation.

Medications:
Hydroxyurea (antimetabolite) reduces the frequency of sickle cell crises and increases fetal hemoglobin. Pain medications (e.g., NSAIDs, opioids) are used during crises. Prophylactic penicillin is given to prevent infections in children.

Prevalence: How common the health condition is within a specific population.
Approximately 1 in 365 African-American births in the U.S.; globally, more common in regions like sub-Saharan Africa, the Middle East, and India.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Having two copies of the sickle cell gene (autosomal recessive inheritance); family history of the condition.

Prognosis: The expected outcome or course of the condition over time.
Chronic and lifelong condition; life expectancy has improved with advances in treatment, but complications can reduce quality of life.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Stroke, acute chest syndrome, infections, organ damage, leg ulcers, gallstones, and severe anemia.

Thalassemia

Specialty: Pediatrics

Category: Hematologic and Oncologic Disorders

Sub-category: Hematologic Disorders

Symptoms:
fatigue; weakness; pale or yellowish skin; slow growth; bone deformities (especially in the face); dark urine; shortness of breath

Root Cause:

How it's Diagnosed: videos
CBC showing microcytic, hypochromic anemia; hemoglobin electrophoresis to detect abnormal hemoglobin; DNA analysis for genetic confirmation.

Treatment:
Blood transfusions (for moderate to severe cases), iron chelation therapy to prevent iron overload, folic acid supplements, and bone marrow transplantation in select cases.

Medications:
Deferoxamine , deferasirox , or deferiprone (iron chelators) are used to prevent iron overload due to frequent transfusions. Folic acid supplements support red blood cell production.

Prevalence: How common the health condition is within a specific population.
High prevalence in Mediterranean, Middle Eastern, South Asian, and African populations; approximately 5% of the global population carries thalassemia genes.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Inheritance of one or two defective hemoglobin genes; more severe forms (e.g., beta-thalassemia major) occur with two defective copies.

Prognosis: The expected outcome or course of the condition over time.
Variable depending on the severity; individuals with mild forms (trait or minor) lead normal lives, while severe forms require lifelong treatment. Bone marrow transplantation can be curative.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Iron overload (from transfusions), organ damage (heart, liver, endocrine system), infections, and bone deformities.
