Common Illnesses Flashcards
MC cause of the common cold
rhinovirus
normal progression of mucus in the common cold
Nasal discharge is initially clear and watery, but soon becomes thick and colored in the first few days. The color could be yellow, white, or green. The drainage remains thick for several days and again becomes watery before the cold is resolved
MC predisposing factor for acute bacterial sinusitis
viral URI
tx of acute bacterial sinusitis
amoxicillin +/- clavulanate
tx for common cold
supportive- heated air, saline drops, menthol vaper
primary bacteria for pharyngitis
Group A, Beta Hemolytic Streptococcal Infections
clinical findings of GABHS
sore throat fever headache nausea, vomiting, abdominal pain Strawberry tongue, sandpaper like rash -Absence of conjunctivitis, coryza, hoarseness, anterior stomatitis, cough, diarrhea Tonsillar hypertrophy patchy, discrete exudate Tender, enlarged anterior cervical nodes Beefy red, swollen uvula, petechiae on the palate and excoriation of nares
variations of GABHS
scarlet fever, Erysipelas, Streptococcal Perianal Infection and balanoposthitis
best lab tests for GABHS
throat culture (first line) & rapid strep test
objectives to tx GABHS
prevent rheumatic fever, not likely to prevent post streptococcal AGN
major complications of GABHS
- retropharyngeal abscessed
- peritonsilar abscessed
tx for retropharyngeal abscessed
surgical drainage
1st line = clindamycin
tx for peritonsilar abscessed
1st line - PCN (clindamycin if pt is allergic)
incision and drainage
Treatment of Steptococcal Tonsillopharyngitis
PCN or amoxicillin
GABHS tx
- PCN (10-30% failure)
- can tx w/ augmentin if there is suspected inactivation of PCN bacteria
acute otitis media MC pathogen
H. influenzae
pathogenesis AOM
- Partial obstruction of Eustachian Tube leading to Eustachian Tube Dysfunction
- Exudation of fluid into middle ear
- negative middle ear pressure
RF for AOM or OME
Age <2 years, much more common
If <6mos, itll happen more times within that year
First episode of AOM when younger than 6 months of age
Absence of breast feeding
Atopy
Chronic sinusitis
AOM vs OME
AOM – Rapid onset of signs and symptoms of inflammation in the middle ear, bulging TM
OME – Inflammation with fluid in the middle ear without signs and symptoms of acute infection (fluid alone sometimes)
AOM criteria
- Presence of middle ear effusion (MEE)
- Inflammation as indicated by a bulging TM-must be
- Otorrhea of new onset
AOM tx
First-line: Amoxicillin (high dose b/c cover highly resistant strep pneumoniae) 80-90 mg/kg/day in two divided doses
Second-line: Amoxicillin-Clavulanate 90 mg/kg/day in two divided doses
If a child has AOM concurrent with conjunctivitis or
had Amoxicillin therapy in the previous 30 days
Amoxicillin-Clavulanate should be the first line agent.
