Febrile Neutropenia
Criteria: Single temperature > 38.3°C or > 38.0° for > 1 hour with an ANC< 500 cells/μL or an ANC expected to decrease to < 500 cells/μL within the next 48 hours
125
Febrile Neutropenia causes
Bacteremia is the most common form of infection * Other common sites include the GI tract (oral or intestinal mucositis, diarrhea), upper and lower respiratory tract infections, urinary tract infection * Diarrhea most commonly caused by Clostridium Difficile and Salmonella * Consider both gram positive and gram-negative organisms
126
Febrile Neutropenia Evaluation
Blood cultures (all central venous access devices/lumens, consider peripheral) * Urinalysis/urine culture if clean-catch, mid-stream specimen available * Chest x-ray in symptomatic patients * CT/Ultrasound for fluid collections, effusions * Respiratory viral screening in symptomatic patients * Stool for infectious studies in symptomatic patients * Lumbar puncture for altered mental status
127
Febrile Neutropenia Management
Low-risk: consider oral, outpatient therapy * Fluoroquinolone monotherapy or fluoroquinolone and amoxicillin-clavulanate * High risk: cover gram negative organisms, strep viridans, and pseudomonas aeruginosa * Hospital admission and antibiotic monotherapy (antipseudomonal beta lactam, fourth-generation cephalosporin, or carbapenem) if stable * Add gram-negative agent or glycopeptide if unstable, resistant pathogen suspected * Also consider adding gram-positive and anaerobic coverage for resistant organisms * If minimal response or signs of decline, therapy should be adjusted for clinical, radiographic, and/or culture data
128
A 2-year-old who is receiving treatment for a neuroblastoma develops fever to 38.9C, lethargy and has oxygen saturations to 95%. The most important, first-line management should include: A. Obtain peripheral blood culture and CBC B. Administration of antibiotics to include 3rd generation cephalosporin along with an antifungal C. Obtain blood cultures from CVL and administer antibiotics to include 4th generation cephalosporin D. Obtain blood culture and lactate level from central line
C. Obtain blood cultures from CVL and administer antibiotics to include 4th generation cephalosporin Most important to give 4th generation cephalosporin in the setting of fever in immunocompromised to cover pseudomonas.

A probable cause of this asymmetry is: A. Congenital caratact B. Retinoblastoma C. Neuroblastoma D. This is a normal finding depending on the position of the eyes
B. Retinoblastoma Asymmetry is called leukocoria.
134
