<body><sec id="Sec1"><title>Introduction</title>
<p>Upper Respiratory tract infections are seen with great frequency in both children and adults and have remarkable economic impact, related to the frequent prescription by physicians of antibiotics, even when the causative agents of infection are not bacteria. About one-fourth of children with sore throat have bacterial pharyngitis and about half of the families with index case have a secondary case [<xref ref-type="bibr" rid="CR1">1</xref>
]. Identification and adequate antibiotic treatment of group A streptococcal sore throat is important for primary prevention of acute rheumatic fever, as it carries approximately 3% risk of development of acute rheumatic fever.</p>
</sec>
<sec id="Sec2"><title>Definition</title>
<p>Soreness is generally described by the patient as pain in the throat without the effort of swallowing and also a painful swallow [<xref ref-type="bibr" rid="CR2">2</xref>
]. <bold><italic>Sore throat</italic>
</bold>
is primary symptom of pharyngitis. The terms “sore throat” and “pharyngitis or pharyngotonsillitis” are often used interchangeably. <bold><italic>Pharyngitis</italic>
</bold>
refers to objective evidence of inflammation of the pharynx, such as exudates, ulceration, or definite erythema. Redness of the throat may occur as part of the general redness of all mucous membranes in a patient with fever. A diagnosis of pharyngitis is justified only when the pharynx is redder than the rest of the oral mucosa.</p>
</sec>
<sec id="Sec3"><title>Etiology</title>
<p>Most sore throats are caused by viruses. Less often, sore throats are due to bacterial infections.</p>

<sec id="Sec7"><title>Approach to the Patient</title>
<p>Majority of the times, history and clinical examination gives clue to etiology (Table <xref rid="Tab1" ref-type="table">1</xref>
). The major challenge is to diagnose GABHS infection, because the signs and symptoms of GABHS pharyngitis overlap with other infections and untreated GABHS can cause serious complications. No single element of the history or physical examination reliably confirms or excludes GABHS pharyngitis.

<p>Several scoring systems have been developed to predict which patients will have GABHS. Use of these does improve quality of care but none of these systems, however, is totally reliable in identifying children who need treatment [<xref ref-type="bibr" rid="CR4">4</xref>
]. A clinical scoring system has been designed in India but it has to be validated for local use. This scoring system uses variables such as age, season, fever, erythema of pharynx, size of tonsil, pharyngeal exudates; lymphadenopathy and pain in throat, and scores are assigned according to throat culture positivity in association with the same. Cut off value of 15 predicts GAS infection with 91% sensitivity and 98% specificity [<xref ref-type="bibr" rid="CR3">3</xref>
].</p>
<p>The evaluation of patient should include the following:</p>

<list list-type="bullet"><list-item><p><italic>Exudates</italic>

</p>
</list-item>
<list-item><p><italic>Membrane</italic>
: Exudates of bacterial pharyngitis may organize as gray-white layer of materials that can be peeled from the pharynx.
<list list-type="bullet"><list-item><p>○ A membrane is seen with infectious mononucleosis, diphtheria and sometimes streptococcal infection. <italic>Arcanobacterium hemolyticum</italic>
and tularemia are rare causes of membranous pharyngitis.</p>
</list-item>
<list-item><p>○ Gray to black adherent membrane, with extension beyond the faucial area (esp. soft palate and uvula), dysphagia, and relative lack of fever suggest a diagnosis of diphtheria.</p>
</list-item>
<list-item><p>○ Oral thrush seen in neonates and infants which can have pseudomembrane (curd like plaques), removal of which may cause mild punctuate bleeding.</p>

</list-item>
<list-item><p><italic>Painful vesicular lesions on pharynx and tonsils</italic>
are characteristic of herpangina. Herpes simplex produces painful vesicles confined to anterior mouth which may sometimes extend to anterior tonsillar pillars.</p>
</list-item>
<list-item><p><italic>Lymphadenopathy</italic>
: Look for anterior (tonsillar) and posterior cervical lymph nodes. Tender anterior lymphadenopathy favors bacterial sore throat. Tender posterior cervical and/or generalized lymphadenopathy favours Ebstein Barr (EB) virus infection.</p>
</list-item>
<list-item><p>Examine for neck swelling, conjunctivitis, auscultatory abnormalities and hepatosplenomegaly.</p>
</list-item>
<list-item><p>Vital signs, including blood pressure, should be recorded. Poor quality of the heart sounds raises the possibility of diphtheritic myocarditis. Absence of a heart murmur or dependent edema should be noted for their relevance to rheumatic fever and glomerulonephritis.</p>
</list-item>
</list>
Common signs and symptoms of streptococcal pharyngitis include sore throat, temperature ≥38.3°C, tonsillar or pharyngeal exudates and cervical lymphadenopathy. Cough, coryza and diarrhea are more common with viral pharyngitis.

<p>A major concern in emergency room for a child with sore throat is not to miss diagnosis of diphtheria and GABHS pharyngitis.
<list list-type="bullet"><list-item><p>Obtain <italic>throat swab</italic>
for bacterial smear and culture including Albert stains for diphtheria. A provisional diagnosis of diphtheria is suggested if typical drum stick organisms are seen in the smear. However, a definitive diagnosis requires growth of <italic>C. diphtherium</italic>
in culture as diphtheroids are commensals in throat.</p>

for GABHS [<xref ref-type="bibr" rid="CR5">5</xref>

]: It is based on nitrous acid extraction of group A carbohydrate antigen from organisms obtained by throat swab. It is highly specific (>95%), and provides immediate results, but has variable sensitivity. Throat culture confirmation of a negative RADT is recommended to increase sensitivity. Confirmation of positive test is not recommended because of very high specificity.</p>

<sec id="Sec9"><title>Throat Swab Sampling Technique</title>
<p>Samples should be obtained by vigorous swabbing of both tonsillar surfaces or fossae and the posterior pharynx [<xref ref-type="bibr" rid="CR6">6</xref>
, <xref ref-type="bibr" rid="CR7">7</xref>
]. Correctly sampled and plated, throat swab culture has 90–95% sensitivity. Swabbing the soft palate and uvula should be avoided, because it dilutes the inoculums.</p>

<sec id="Sec10"><title>Management</title>
<p>GABHS pharyngitis is self-limiting illness. Antibiotic treatment provides acute symptom relief, prevent suppurative (otitis media, sinusitis, quinsy) and non suppurative complications, and reduce communicability. Antibiotics reduce incidence of rheumatic fever by more than two third [<xref ref-type="bibr" rid="CR8">8</xref>
]. Clinical decision guideline for sore throat is given in Fig. <xref rid="Fig1" ref-type="fig">1</xref>
.

<graphic xlink:href="12098_2011_467_Fig1_HTML" id="MO1"></graphic>
</fig>
</p>
<p>Clinical features, epidemiological criteria and expert clinician judgment with or without supportive investigation usually indicate need for antibiotics. Currently used score for decision making in pharyngitis has been adapted by adding age to four components of original Centor score (absence of cough, swollen and tender anterior cervical nodes, temperature >38°C and tonsillar exudates or swelling) [<xref ref-type="bibr" rid="CR9">9</xref>
]. Each component is given 1 point; age of 3–14 years carries 1 point while that of 14–44 years, zero. Patients with a score of zero or 1 do not require testing or antibiotic therapy. Patients with score of 2 or 3 should be tested and prescribed antibiotics if found positive while patients with score of 4 or higher, are at high risk of streptococcal pharyngitis and should be given empiric treatment [<xref ref-type="bibr" rid="CR10">10</xref>
].</p>
<sec id="Sec11"><title>Antibiotics</title>
<p>Based on cost, narrow spectrum of activity, safety, and effectiveness, penicillin is the drug of choice [<xref ref-type="bibr" rid="CR10">10</xref>
, <xref ref-type="bibr" rid="CR11">11</xref>
]. Shorter duration of treatment increases risk of bacteriological recurrence [<xref ref-type="bibr" rid="CR12">12</xref>
] Inappropriate use of macrolides for treatment of GABHS pharyngitis has been the main cause of resistant strains in western countries [<xref ref-type="bibr" rid="CR13">13</xref>
]. The various alternatives to penicillin and the dosage of antibiotics are given in Table <xref rid="Tab3" ref-type="table">3</xref>
