Study Notes
Infiltration of the CNS
- Increased intracranial pressure can lead to severe symptoms like headaches, vomiting, and coma.
- Symptoms include papilledema and nuchal rigidity, potentially progressing to death.
Hypermetabolism
- Causes cell nutrient deprivation, leading to anorexia, weight loss, muscle atrophy, and fatigue.
Leukemia vs. Leukocytosis
- Leukemia involves proliferation of one type of WBC, originating from hematopoietic stem cells, categorized as lymphoid or myeloid.
- Acute leukemia presents low WBC counts due to cells being halted at the blast stage and progresses rapidly.
- Chronic leukemia features mature cells and progresses more slowly.
AML & ALL
- Acute Myeloid Leukemia (AML) affects all ages, linked to genetic factors, with a 50% survival rate post-treatment.
- Acute Lymphocytic Leukemia (ALL) is the most common childhood leukemia, peaking between ages 2-5, with an 80% survival rate with treatment.
Stages of Leukemia Treatment
- Treatment protocols are tailored to leukemia types, employing multi-drug regimens for efficacy.
Induction
- Focuses on achieving remission by clearing bone marrow of disease over 4-6 weeks.
Consolidation
- Aims to eliminate residual cells over 4-8 months, sometimes using intrathecal chemotherapy for CNS prevention.
Maintenance
- Continued treatment lasting 2-3 years with less intensive chemotherapy to maintain remission.
Relapse Treatments
- Re-induction therapy using different drugs occurs if leukemia relapses after initial treatment stages.
Intrathecal Chemotherapy
- Administers drugs directly into spinal fluid for CNS infiltration treatment.
Sarcomas
- Rhabdomyosarcoma and Osteosarcoma are notable types affecting muscle or bone tissues in children.
Osteosarcoma
- Most common skeletal tumor in children, typically occurs in brisk growth phases (ages 13-14).
- Metaphysis of long bones is often affected; metastasis rates are high.
- Symptoms include pain and localized swelling.
Osteosarcoma Treatment
- Initial chemotherapy aims to reduce tumor size pre-surgery, followed by surgical intervention (amputation or limb-salvage).
Toxoplasma Gondii
- Transmitted via cat feces or undercooked meat, posing risks during pregnancy.
- Congenital toxoplasmosis can lead to severe neonatal symptoms, primarily if the mother is infected in the first trimester.
Giardia Lamblia
- Common waterborne protozoan causing non-bacterial diarrhea, particularly in children through fecal-oral transmission.
Roundworms (Ascaris lumbricoides)
- These worms can grow up to 13 inches, causing malnutrition and abdominal discomfort.
- Diagnosis and treatment options include albendazole or mebendazole.
Pinworms (Enterobius vermicularis)
- Tiny worms causing intense perianal itching, treated with similar antiparasitic medications as roundworms.
Hookworms (Necator americanus)
- Can lead to severe gastrointestinal damage and malnutrition, especially in warm Southern US climates.
- Initial symptoms include localized itching, followed by abdominal pain and anemia.
Tinea Capitis (Scalp Ringworm)
- Affects children, causing hair loss and fine scaling. Treatment includes griseofulvin and selenium sulfide shampoo.
Tinea Corporis (Ringworm)
- Fungal skin infection with circumscribed patches, treated with topical antifungals.
Tinea Cruris (Jock Itch)
- Fungal infection in warm, moist skin areas, with treatment similar to other tinea infections.
Tinea Pedis (Athlete's Foot)
- Fungal foot infection characterized by itching and scaling. Treatment includes antifungals and keeping the feet dry.
Pediculosis (Lice Infestation)
- Transmitted through contact, leading to severe itching and skin irritation. Treatment typically involves permethrin.
Scabies
- Contagious skin infection from mites requiring direct contact for transmission. Symptoms include intense itching and rash. Treatment often involves albendazole or mebendazole.
HIV/AIDS in Infants
- Most commonly acquired perinatally; diagnosis requires HIV DNA or RNA assays due to maternal antibody interference.
- Symptoms of AIDS include failure to thrive and recurrent infections.
- Treatment involves combination antiviral therapy based on CD4 counts, tailored to age and disease severity.
