Definition of DIC | alteration of normal coagulation mechanism triggered by tissue injury such as infection, trauma, malignancy, etc. |
Symptoms of DIC | Bleeding, thrombosis, tissue ischemia. Respiratory failure, abdominal, renal failure, seizures. |
Diagnosis of DIC | Co-agulation studies. Especially D-dimer are diagnositic. |
Management of DIC | Remove cause/ event. Manage shock, respiratory compromise, acidosis. Vit K for clotting. |

Description / symptoms EBV | herpes family. Can be latent or active. Causes mono. Prodrome of fever, sore throat, malaise, fatigue. Cervical LAD, |
Diagnosis & management of EBV | monospot or mono tesr or viral antigen. Supportive care. Spleen gaurd & spleen caution if HSM. |
What are the 'hallmark" symptoms that would warrant testing for pertussis in an infant | lymphocytosis with classic cough. PCR for fast results, Culture for 100% specificity. |
Teen with fever, malaise ST. 3+ tonsils with exudate. anterior and posterior cervical LAD & splenomegaly. What labs will you order | CBC with diff, EBV specific IgG & IgM. Typically leukocytosis with 60%> lymphocytosis,& 50% pt with mild thrombocytopenia. |
Typical symptoms of CMV | pneumonitis, hepatomegaly, hepatitis & rashes |

Diagnostics/Labs of enterovirus | cell culture isolation, PCR. |
Presentation and diagnostics of herpes simplex | Gingivostomatitis, genital herpes. Most concerning system based illness is encephalitis, can be congenitally acquired. Diagnosis: cell culture, antibody detection. |
Management of HSV | preventative tx with antiviral agents. Acyclovir etc. |
What disease does parvo B19 cause to school age children and what condition if transmitted perinatally? | fifth disease in school aged children. Presents with fever, arthralgias, rash. Perinatal transmission = hydrops fetalis. |
Management of hepatitis | based on thype and symptoms, consult GI, hepatologist, |

Organisms responsible for systemic infections most commonly associated with fever of unknown origin in children (14) | salmonella, tuberculsosis, rickettsial, lyme, Cat scratch, histo, toxo,coccidioidomycosis, Malaria, Hepatitis, CMV, mono, syphillis, atypical prolonged common viral dx. |
who has highest risk for occult bacteremia? A. 1 mth old toxic appear fever of 102°FB. 2 mth old, 3 days post imm fever to 101.4°F C. 3 mth resp congestion, wheezing 102.4°F D. 6 mth old 103°F, whose sibs recently had diarrhea | A High risk children inc infants < 1MTH & B/T 1&3 mth, appear toxic & have no other symptoms to suggest illness. As infants age, fever is less of a concern, especially in the presence of other symptoms such as vomiting, diarrhea, cough or congestion. |
