Rhino sinusitis most often caused by…
VIRUS
Think bacterial rhino sinusitis when..
- Symptoms >10 days w/o improvement
- Severe symptoms (fever >102, facial pain lasting longer than 3 days, purulent nasal drainage)
- Symptoms got better and then worse again
Rhinosinusitis treatment VIRAL
OTC analgesics, intranasal steroids (budesonide, flucticasone (flonase, nasacort, nasonex), decongestants sometimes (no longer than 3 days)
Rhinosinusitis treatment Bacterial
- amoxicillin or amoxicillin-clavulante (Augmentin is better, generally for pts with risk factors for resistance, give if pt looks sick – region with resistance, antibiotic use in past month, hospitalization in last 5 days, immunocompromise, comorbidities, severe infection-temp >102)
- (Penicillin allergic) Doxycycline (not in pregnancy) OR 3rd generation cephalosporin (cefixime, cefpodoxime) with or without clindamycin. OR respiratory fluoroquinolone (last line d/t side effects-prolonged QT, not in pregnancy) (levofloxacin, moxifloxacin)
Pharyngitis/tonsillitis most often caused by….
VIRAL
pharyngitis/tonsillitis when caused by bacteria think…
group A streptococcus
pharyngitis/tonsillitis can also be caused by….
Group C&G Strep, STI, diptheriae, EBV, Cytomegalovirus, Herpes simplex
Center scoring for rapid strep test…
Criteria Absence of cough: +1 Swollen, tender anterior lymph nodes: +1 Temp> 100.4 +1 Age 3-14 +1 15-44 0 45 or older -1
Score
1-2 no further testing or antibiotics
3-4 rapid strep test and treat
5 consider empiric treatment
Other diagnostics to order for pharyngitis/tonsillitis
throat culture (for high risk, DO NOT empirically treat before results are obtained), Monospot (false negative if tested within 7 days of symptom onset)-could do CMP (liver enzyme elevation with mono), CBC (lymphocytosis and atypical lymphocytes), cytomegalovirus will not show up on monospot, EBV & CMV serology testing may be used if repeat monospot is negative
Treatment for tonsillitis from group A Strep
- Penicillin V or Amoxicillin
- (penicillin allergy) Cephalosporins or Macrolide. Mild non-IgE reactions: 2nd or 3rd generation cefuroxime, cefdinir, cefpodoxime. Any possible IgE reaction/severe penicillin reaction: Macrolide- azithromycin, if macrolide resistant strep-clindamycin
Mono treatment
supportive care, no steroids in routine cases, avoid contact sports for a few months d/t spleenic rupture risk
Peritonsillar Abscess S/S
unilateral severe throat, muffled voice, fever, pooling saliva, drooling, neck swelling and pain, soft palate appears to be caving in
Peritonsillar Abscess diagnostics
CT
Peritonsillar Abscess treatment
ENT consult, steroids, Augmentin OR Clindamycin
Epiglottitis
EMERGENCY
Acute Otitis Media most common cause
upper respiratory infections, strep pneumoniae. May also be caused by H. influenza, moraxella cararrhalis, staph aureus
AOM S/S
earache, decreased hearing, dizziness, fever, donut looking bulging TM and yello purulent color (red TM does NOT indicate infection), decreased TM motility, otorrhea
AOM with effusion S/S
Fluid in middle ear without S/S of infection, TM dull non-bulging, decreased motility, ear-fluid lines
AOM Treatment
- Amoxicillin or Augmentin
- (penicillin allergy) Non IgE Cephalosporin (cefdinir, cefpodoxime, cefuroxime, ceftriaxone). Severe IgE allergy: doxycycline (NOT in pregnancy) OR macrolide (azithromycin, clarithromycin)
Upper respiratory infections cause
VIRAL
Otitis Externa cause
bacterial, P. aeruginose is most common, could also be staph epidermidis, staph aureus, fungal
Otitis Externa S/S
itching, plugging of ear, ear pain, ear discharge, pain on manipulation of pinnae, eczema of pinnae, ear canal red, containing discharge and debris
Otitis Externa Treatment
Clean ear canal and outer ear (peroxide with water). Antibiotics: Topical floroquinolones ofloxacin and ciprofloxacin or cipro combined with dextamethasone, Polymyxin B and neomycin (aminoglycoside), Tobramycin and gentamicin (NOT if TM is ruptured-ototoxic)
Labyrinthitis definition
ACUTE inflammation or viral infection of inner ear (labrynth)
