Coxsackie A16
Infectious mononucleosis is caused by whch virus
Epstein-Barr virus
Most common route of transmission by EBV
Oral contact
Most common diagnostic assay used for EBV
Heterophile agglutination test
Antibiotics contraindicated in EBV infection
β-lactams
Most common cause of bacterial pharyngitis
GABHS
Findings associated with scarlet fever
descending rash + strawberry tongue
Diagnostic of choice in GABHS pharyngitis
Throat culture
Indications for prophylaxis in asymptomatic carriers of GABHS:
- RF History, 2. community outbreak of RF, PSGN, invasive GABHS, 3. possible tonsillectomy, 4. symptomatic GABHS in the family
Second-line antibiotics in GABHS
1st gen cephalosporin, clindamycin, clarithromycin, azithromycin
Light’s criteria for tonsillectomy
≥ 7 episodes in 1 year, ≥ 5 episodes/year in 2 years, ≥ 3 episodes/year in 3 years
Bacteria with a Chinese character appearance on GS
C diphtheriae
APSGN follows ___ weeks after a GABHS pharyngitis
1 to 2
Diagnostic criteria for PANDAS
OCD/tic disorder onset between 3 yeas of age and puberty; episode, abrupt psychiatric symptoms or exacerbtions; culture-confirmed GABHS infection;abnormal NE: motor hyperactivity, ⊖ chorea
Most common virus associated with croup
Parainfluenza virus types 1, 2, 3
Triad of croup
hoarseness + expiratory stridor + upper airway obstructioin
Important clinical findings in croup:
- type of stridor, 2. RR, 3. retractions, 4. air entry, 5. anxiety/restlessness, 6. color, 7. desaturations, 8. level of conscousness
Intubation rate of croup patients
5%
Pathology causing obstruction in croup and sign in x-ray
subglottic swelling, steeply sign
