A ten-year-old boy is brought to clinic by his mother who states that the boy has been listless and not eating. She also notes that he has been easily bruising without trauma as he says he is too tired to go out and play. He says his bones hurt sometimes. Mother states the child has had intermittent fevers that respond to acetaminophen. Maternal history negative for pre, intra, or post-partum problems. Child’s past medical history negative and he easily reached developmental milestones. Physical exam reveals a thin, very pale child who has bruises on his arms and legs in no particular pattern. The APRN orders complete blood count (CBC), and complete metabolic profile (CMP). The CBC revealed Hemoglobin of 6.9/dl, hematocrit of 19%, and platelet count of 80,000/mm3. The CMP demonstrated a blood urea nitrogen (BUN) of 34m g/dl and creatinine of 2.9 mg/dl. The APRN recognizes that the patient appears to have acute leukemia and renal failure and immediately refers the patient to the Emergency Room where a pediatric hematologist has been consulted and is waiting for the boy and his mother. The diagnosis of acute lymphoblastic leukemia (ALL) was made after extensive testing.
Question 2 of 2:
How does renal failure occur in some patients with ALL?
QUESTION 3
A 12-year-old female with known sickle cell disease (SCD) present to the Emergency Room in sickle cell crisis. The patient is crying with pain and states this is the third acute episode she has had in the last nine months. Both parents are present and appear very anxious and teary eyed. A diagnosis of acute sickle cell crisis was made. Appropriate therapeutic interventions were initiated by the APRN and the patient’s pain level decreased, and she was transferred to the pediatric intensive care unit (PICU) for observation and further management.
Question 1 of 2:
What is the pathophysiology of acute SCD crisis and why is pain the predominate feature of acute crises?
