SORE THROAT:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
In a sore throat with typical exudates very suggestive of streptococcal pharyngitis, a throat culture may be all one needs before starting definitive antibiotic therapy. In the more difficult cases, screening for streptococcal antigens (streptozyme test and ASO titer) might be indicated. An ASO titer is particularly important when one suspects rheumatic fever. If the patient's streptococcal sore throat persists, a Monospot test and a culture for gonorrhea should be done. Although there are hardly any false-negative Monospot tests, there are 10% false positives, and that should be kept in mind. A blood smear for atypical lymphocytes may be helpful, as well as a heterophile antibody titer in those cases.

MOUTH PIGMENTATION:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
Routine laboratory workup includes a CBC, sedimentation rate, urinalysis, chemistry panel, and a VDRL test. If arsenic poisoning is suspected, hair analysis for arsenic should be done. If Addison's disease is suspected, a 24-hr urine collection for 17-hydroxysteroids and 17-ketosteroids should be done. The rapid ACTH test is a suitable alternative but usually more expensive. If Peutz-Jeghers syndrome or acanthosis nigricans is suspected, a GI series with a small bowel follow-through and a barium enema may be necessary. Endoscopy procedures may also be useful in certain cases.

Mouth lesions:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Begin your evaluation with a thorough history. Ask the patient when the lesions appeared and whether he has noticed pain, odor, or drainage. Also ask about associated complaints, particularly skin lesions. Obtain a complete drug history, including drug allergies and antibiotic use, and a complete medical history. Note especially malignancy, sexually transmitted disease, I.V. drug use, recent infection, or trauma. Ask about his dental history, including oral hygiene habits, the frequency of dental examinations, and the date of his most recent dental visit.
Next, perform a complete oral examination, noting lesion sites and character. Examine the patient’s lips for color and texture. Inspect and palpate the buccal mucosa and tongue for color, texture, and contour; note especially painless ulcers on the sides or base of the tongue. Hold the tongue with a piece of gauze, lift it, and examine its underside and the floor of the mouth. Depress the tongue with a tongue blade, and examine the oropharynx. Inspect the teeth and gums, noting missing, broken, or discolored teeth; dental caries; excessive debris; and bleeding, inflamed, swollen, or discolored gums.
Palpate the neck for adenopathy, especially in patients who smoke tobacco or use alcohol excessively.

Throat pain:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Ask the patient when he first noticed the pain, and have him describe it. Has he had throat pain before? Is it accompanied by fever, ear pain, or dysphagia? Review the patient’s medical history for throat problems, allergies, and systemic disorders.
Next, carefully examine the pharynx, noting redness, exudate, or swelling. Examine the oropharynx, using a warmed metal spatula or tongue blade, and the nasopharynx, using a warmed laryngeal mirror or a fiber-optic nasopharyngoscope. Laryngoscopic examination of the hypopharynx may be required. (If necessary, spray the soft palate and pharyngeal wall with a local anesthetic to prevent gagging.) Observe the tonsils for redness, swelling, or exudate. Obtain an exudate specimen for culture. Then examine the nose, using a nasal speculum. Also, check the patient’s ears, especially if he reports ear pain. Finally, palpate the neck and oropharynx for nodules or lymph node enlargement.

Sore Throat:
Diagnostic Approach
(Field Guide to Bedside Diagnosis)
The most important consideration is whether the patient has a group A strep infection because prompt treatment prevents rheumatic fever. The findings of fever, tender anterior cervical adenopathy, and tonsillar exudate can be combined to make the diagnosis more or less likely. Rapid antigen tests have a sensitivity of 80% to 90% and specificity of 95% to 100%, so give a reasonably accurate diagnosis. Because of limitations in sensitivity however, patients with a high suspicion on clinical grounds should have a backup culture taken.
Prior probability in an adult population with sore throat is 5% to 10%, and in a pediatric population 20% to 25%. A prominent sore throat out of proportion to the degree of pharyngeal inflammation should raise the possibility of acute epiglottitis and acutely impending airway compromise. Persistent unilateral tonsillar enlargement in a young adult without sore throat should raise the suspicion of lymphoma.

Sore Throat:
Diagnostic Approach
(The Diagnostic Approach to Symptoms and Signs in Pediatrics)
Historyand physical exam provide important clues for proper diagnosis ofsore throat.Most common clinical dilemma in childwith pharyngitis is whether pathogen is virus or group A Streptococcus.Tests to detect streptococcal antigen may be diagnostic, but ifresults of such tests are negative, throat culture should be performed.Because many cases of pharyngitis aredue to viruses, antibiotic use should be guided by antigen detectiontests or culture. Presence of conjunctivitis, cough, rhinitis, andhoarseness suggests viral etiology. Infectious mononucleosis isalso a consideration, especially in older children and adolescents.Neck radiography, flexible laryngoscopy,and CT are useful with suspected foreign body or retropharyngeal/lateralpharyngeal abscess.
