Diagnosis And Treatment Of URTIs Guidelines And Recommendations Sayed Ismail , MD Professor of pediatrics [email protected]
بسم الله الرحمن الرحيم
Objectives What Are The common URTI ? The guidelines in d iagnosis of common URTI The guidelines in treatment of URTI
Upper respiratory tract infection (URTI) The upper respiratory tract includes airways outside the thorax The sinuses Nasal passages Middle ear Pharynx Larynx
UTRI Nasopharyngitis ( the common cold) Pharyngitis AOM Rhinosinusitis (sinusitis) Parapharyngeal abscess Epiglottitis Laryngitis Croup
Viruses cause 80–90% of childhood respiratory infections. Bacteria Strep. Pyogenes Strept . Pneumoniae H influenzae M catarrhalis staph aureus , pseudomonas Mixed aerobes and anaerobes Pathogens of URTI
Frequency of Different Viruses Detected in Nasopharyngeal Swabs of Children With URTI in 2009-2010 Archives of Pediatric Infectious Diseases. 2012 October ;
What are The 4 most frequent URTIs ? The common cold Pharyngitis and Tonsillitis Acute otitis media Sinusitis Shaun et al, Annals of Clinical Microbiology and Antimicrobials 2004
Common cold
Common Cold Commonest Viral URTI The body can never build a solid resistance to it ( changes in antigenicity) › 200 viruses Rhinovirus Coronavirus RSV Parainfluenza virus Influenza virus Metapneumovirus Adenovirus coxsackieviruses , Others Heikkinen T, Jarvinen A. The common cold. Lancet. 2003;361:51-59.
Rhinorhea early watery Later , thicker and darker. Nasal obstruction Difficulty in feeding in infants as their noses are blocked and this obstructs breathing Mild or no Fever Cough Sore Throats Sneezing Duration 4-10 days Heikkinen T, Jarvinen A. The common cold. Lancet. 2003;361:51-59.
Colds in healthy school children . Pappas et al, Pediatr Infect Dis J 2008
Complications Acute exacerbations of asthma Secondary bacterial infections 2% of colds are complicated Rhinosinusitis Otitis media .. Most common Pneumonia
1- How can I tell that this is a Cold not a Flu? Colds Flu 1- No or low grade fever High fever 2- No or mild systemic manifestations Systemic manifestations
2- Features Suggestive Allergic rhinitis Prolonged sneezing . Redness, swelling and itching of the eyes Itchy and runny nose Itchy throat , Itchy skin Dennie's lines Allergic shiners . (bluish-brownish discoloration around the eyes ) Dennie's lines
Allergic crease Allergic shiners.
Treatment of cold Symptomatic : Analgesics Antihistamines Decongestants Antitussives
Antibiotics Delayed antibiotics for complications of colds
70% of GP and 50% of Pediatricians prescribe antimicrobial agents if mucopurulent nasal secretions seen in first days of cold. Indeed, purulent sputum production is a normal part of viral infection Color and opacity do not reliably distinguish viral from bacterial illness. Nyquist et al, JAMA. 1998;279:875-877
Clinical Diagnosis History Examination Pharyngeal exudates Enlarged and tender cervical node. Tonsillopharyngeal erythema Red uvula Palatal petechiae 3- Lab . Rapid diagnostic tests , if negative Throat culture. Leung et al , Expert Rev Mol Diagn. 2006 Sep;6(5):761-6 Canada
Scarlet Fever
Scarlet fever Desquamation Toward the end of the first week of illness, the rash begins to fade and is followed by a desquamation over the trunk, which progresses to the hands and feet.
Patient Characteristic Points History of fever or temperature >38ºC +1 Absence of Cough +1 Tender Anterior Cervical Adenopathy +1 Tonsillar Swelling or exudates +1 Age <15 years +1 Age >45 years -1 Score % Likelihood of GAS -1 or 0 2-3 1 4-6 2 10-12 3 27-28 4 or 5 38-63 Score Suggested Management -1 or 0 No antibiotics or culture required 1 No antibiotics or culture required 2 Culture all; treat patients with positive results 3 Culture all; treat patients with positive results 4 or 5 Treat with antibiotics without culture Clinical decision rule for streptococcal pharyngitis
Clin Infect Dis 2012 ; 55:1279 To optimise the use of antibiotics, in 2012 the Infectious Diseases Society of America (IDSA) recommended the use of pharyngeal swabs to take samples for bacterial cultures or rapid diagnostic tests because the clinical features alone do not reliably discriminate between GAS and viral pharyngitis Recommendation:
Leung et al , Expert Rev Mol Diagn. 2006 Sep;6(5):761-6 Canada.
What about antistreptolysin O titer? Streptococcal antibodies ( antistreptolysin O) levels do not peak until 4-5 weeks after the onset of pharyngitis . Therefore, testing for these antibodies has no role in the diagnosis of acute pharyngitis
The throat is red and tonsils covered with a whitish material. Enlarged lymph nodes HSM Fatigue. EBV and streptococcal tonsillitis appear quite similar. A throat culture and blood studies may be necessary to make an accurate diagnosis. Infectious Mononucleosis
This patient with infectious mononucleosis had been placed on ampicillin which resulted in a macular- papular skin rash Cervical lymphadenopathy
Streptococcal Pharyngitis Infectious Mononucleosis Cervical adenopathy No splenomegaly or Hepatomegaly Fatigue is less prominent Lab. Rapid diagnostic tests Throat culture CBC Generalised lymphadenopathy HSM Fatigue Lab. Blood smear CBC Monospot test Serology Petechiae are present on the posterior hard palate
Scarlet fever DD Typical scarlet fever is not generally difficult to diagnose, but it may be confused with: Roseola Kawasaki syndrome Drug eruptions Toxigenic S aureus infections .
Roseola Appears first on chest and abdomen Rose-colored May spread to arms, legs, neck, and face Lasts for a few hours to a few days and does not itch Scarlet fever
Kawasaki syndrome (a) Red, cracked lips and conjunctival inflammation. (b) Peeling of the fingers, which developed on the 15 th day of the illness.
Drug eruptions (dermatitis medicamentosa ) erythematous , morbilliform or maculopapular ), urticaria , fixed drug eruptions, and erythema multiforme are the most common. urticarial reaction from Augmentin
Toxic Shock Syndrome Dx : 5/6 Critera : Fever, rash, hypotension, 3 or more organs involved
Vesicles with ulceration in gingivostomatitis . 3 year old boy with primary herpetic infection
Kissing" Tonsils Difficulty breathing, including loud snoring, gasping, and even sleep apnea resulting in fatigue due to enlarged tonsils and/or adenoids
49 PARAPHARYNGIAL ABCESS
Penicillin remains the drug of choice Single-dose IM of benzathine penicillin is effective Alternative choices : Cephalexin ,Erythromycin ,clarithromycin or azithromycin For recurrent cases Clindamycin or Amoxicillin- clavulanic acid for 10 days Bisno et al, Infectious Diseases,Society of America. Clin Infect Dis 2002;35:113-25.

Fever, earache are present in (90%) of AOM cases. Present in 72% children without AOM. So, clinical history alone is poorly predictive of the presence of AOM. Niemela et al Pediatr Infect Dis J. 1994;13 :765 –768
Modality Comments Acetaminophen, ibuprofen For mild to moderate pain, mainstay of pain management for AOM Benzocaine ( Auralgan , Americaine Otic ) Additional but brief benefit over acetaminophen in patients >5 y Naturopathic agents ( Otikon Otic Solution) Comparable with ametocaine / phenazone drops ( Anaesthetic ) in patients >6 y Narcotic analgesia with codeine or analogs For moderate or severe pain; requires prescription; risk of respiratory depression Tympanostomy / myringotomy Requires skill and entails potential risk PEDIATRICS Volume 131, Number 3, March 2013

Criteria for Initial Antibacterial-Agent Treatment in Children With AOM Severe AOM ( bilateralor unilateral) in children 6 months and older with severe signs or symptoms ( ie , moderate or severe otalgia or otalgia for at least 48 hours or temperature 39°C or higher). Non severe bilateral AOM in young children : 6 months - 23 months of age PEDIATRICS Volume 131, Number 3, March 2013
Criteria for Initial Antibacterial-Agent Treatment or Observation in Children With AOM Non severe unilateral AOM in young children : The clinician should either prescribe antibiotic therapy or offer observation with close follow-up for unilateral AOM in children 6 months to 23 months of age without severe signs or symptoms begin antibiotic therapy if the child worsens or fails to improve within 48 to 72 hours of onset of symptoms. Nonsevere AOM in older children : children 24 months or older without severe signs or symptoms ( ie , mild otalgia for less than 48 hours and temperature less than 39°C PEDIATRICS Volume 131, Number 3, March 2013
Initial Antibacterial Treatment Initial Antibacterial-Treatment or Observation in Children Severe AOM Non severe bilateral AOM in young children Non severe unilateral AOM in young children (6-24mo) Nonsevere AOM in older children( more than 24mo) Criteria for Initial Antibacterial-Agent Treatment or Observation in Children With AOM PEDIATRICS Volume 131, Number 3, March 2013
