2. 2 Acute tonsillitis Acute pharyngitis Acute otitis media Acute sinusitis Common cold Acute laryngitis Otitis externa Mastoiditis Acute apiglottis Upper Respiratory Tract Infections

3. / 423 Objectives At the end of this session, the participants should be able to; –List upper respiratory tract infections –Make differential diagnosis between URTI –Define criteria for antibiotic use –Apply and interpret the McIsaac scoring

4. / 424 Bacteria –S. pyogenes –C. diphteriae –N. gonorrhoeae Viruses –Epstein-Barr virus –Adenovirus –Influenza A, B –Coxsackie A –Parainfluenzae Tonsilitis-pharyngitis

5. / 425 < 3 years –  100 % viral 5-15 years –15-30 % GABHS Adult –10 % GABHS Causative organisms

6. / 426 Spreads by close contact and through air Spread more in crowded areas (KG, school, army..) Most common among 5-15 age group More frequent among lower socio- economic classes Most common during winter and spring Incubation period 2-4 days Due to streptococci:

7. / 427  Sore throat  Anterior cervical LAP  Fever > 38  C  Difficulty in swallowing  Headache, fatigue  Muscle pain  Nausea, vomiting Signs/symptoms  Tonsillar hyperemia / exudates  Soft palate petechia  Absence of coughing  Absence of nose drip  Absence of hoarseness

8. / 428 Having additional rhinitis, hoarseness, conjunctivitis and cough Pharyngitis is accompanied by conjunctivitis in adenovirus infections Oral vesicles, ulcers point to viruses Viral tonsillitis/pharyngitis

10. / 4210 GABHS Epstein-Barr virus Adenovirus Human herpesvirus type 6 Tularemia HIV infection Lymphadenopathy

11. / 4211 Throat swab –Gold standard Rapid antigen test –If negative need swab ASO –May remain + for 1 year WBC count Peripheral smear Laboratory

12. / 4212 Pathogens looked for –Group A beta hemolytic streptococci –C. diphteriae (rare) –N. gonorrhoeae (rare) If GABHS do we need antibiogram? –Is there resistence to penicilline? Throat Culture

13. / 4213 Supurative complications –Abscess –Sinusitis, otitis, mastoiditis –Cavernous sinus thrombosis –Toxic shock syndrome –Cervical lymphadenitis –Septic arthritis, osteomyelitis –Recurrent tonsillitis/pharyngitis Nonsupurative complications –Acute romatoid fever –Acute glomerulonephritis Tonsillitis due to Streptococci

14. / 4214 Prevention of complications Symptomatic improvement Bacterial eradication Prevention of contamination Reducing unnecessary antibiotic use Aim of Treatment

15. / 4215 Many different antibiotics can eradicate GABHS from pharynx Starting treatment within 9 days is enough to prevent ARF Treatment

16. / 4216 Tetracycline Sulphonamides Co-trimoxasole Cloramphenicole Aminoglycosides Antibiotics NOT to be used

17. / 4217 Control culture after full dose treatment? – NO If history of ARF: –Take control culture after treatment No need to screen or treat carriers GABHS

18. / 4218 Developed by Mc Isaac and friends Decreases antibiotic usage by 48% No increase in throat swabs Mc Isaac Scoring http://www.cmaj.ca/cgi/content/abstract/163/7/811

22. / 4222 85% of children up to 3 years experience at least one, 50% of children up to 3 years experience at least two attacks AOM is usually self-limited. Rarely benefits from antibiotics. 81 % undergo spontaneus resolution. Acute Otitis Media

23. / 4223 Symptoms –Autalgia –Ear draining –Hearing loss –Fever –Fatigue –Irritability –Tinnitus, vertigo Otoscopic findings –Tympanic membrane erythema –Inflammation –Bulging –Effusion Hearing loss Signs and Symptoms
