CASE STUDY: ACUTE EXUDATIVE TONSILLITIS

CASE STUDY: ACUTE EXUDATIVE TONSILLITIS

This is a case of a 17-year old male who presented with an acute onset of sore throat, painful swallowing, hoarseness, bilateral ear pain, headache, body malaise, and fever. The physical findings of enlarged hyperemic tonsils with yellowish exudate along with presenting symptoms is suggestive of bacterial etiology. An initial diagnosis of Acute Exudative Tonsillitis was made with differential diagnoses of Acute Mononucleosis, Peritonsillar Abscess and Gonococcal Pharyngitis. Diagnotic tests to confirm initial diagnosis and to rule out the differential diagnoses include Rapid Antigen Detection Test, throat culture for Group A Beta Hemolytic Streptococcus and Neisseria Gonorrhea, Monospot test. Once diagnosis is confirmed and GABHS is established as the causative agent, empiric antibiotic treatment should be started immediately. Penicillin V is the first line of antibiotic but Amoxicillin is most often prescribed. Antibiotic treatment should be completed for 10 days. This ensures relative protection from complications such as rheumatic fever. In patients with Penicillin or Amoxicillin allergy, Macrolide is an alternative choice with the advantage of shorter antibiotic treatment, typically 3 – 5 days, which translates to better patient compliance and a greater chance of completion of the full course of antibiotic therapy. Supportive measures include bed rest, oral hydration, analgesics and steroids. Patient should be educated about personal hygiene with emphasis on hand washing, avoid touching mouth, nose, or eyes, keeping distance from infected individuals and safe sex practice.

ASSESSMENT:

PRIMARY DIAGNOSIS: Acute Exudative Tonsillitis

The patient is this case study presented with an acute onset of sore throat, fever, odynophagia (painful swallowing), hoarseness, and otalgia (ear pain) coupled with the physical findings of erythematous and edematous enlargement of the tonsils bilaterally and presence of anterior cervical lymphadenitis which strongly suggest a diagnosis of Acute Tonsillitis. The presence of yellowish exudates is highly suggestive of bacteria as the etiologic agent of the disease thus descriptive of an exudative type of tonsillitis. The patient’s

course of illness patterns that of the classic presentation of Acute Tonsillitis. This is further strengthened by a positive history of exposure to an individual who presented with the same symptoms.

PATHOPHYSIOLOGY:

Tonsillitis is defined as inflammation of the tonsils. Tonsils are part of the lymphoid system of the body and has a significant role in fighting infections. They appear as pink fleshy structures on each side of the pharynx and are equal in size. Tonsils typically have pits called crypts running through its mucosa which are colonized by different types of microorganisms. Microscopically, tonsils also have lymph nodules which are made up of immune cells particularly B cells, T cells, and macrophages. Tonsils are part of the Waldeyer’s ring which consists of the palatine, lingual, and tubal tonsils together with the adenoids. Until the age of 6, tonsils are expected to be hyperplastic after that they start to regress in size and shrink by 12 years of age. When a patient has tonsillitis, the palatine tonsils are mainly involved. Palatine tonsils are highly vascularized which is why bleeding is one of the most common post operative complication following tonsillectomy.

Tonsillar invasion by either viral or bacteria result to infection. Insults caused by microorganism leads inflammatory responses. The mode of transmission is droplet infection by either close or direct contact (coughing, sneezing, kissing, touching contaminated object). Common viruses causing tonsillitis include Ebstein Barr virus, Adenovirus, Rhinovirus, Coronavirus, Influenza and Parainfluenza viruses while the main bacterial etiologic agent involved is Group A Beta-hemolytic Streptococcus (GABHS), however Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenza have also been identified as

possible causes. Viral etiology is more common than bacterial. It is therefore crucial for the health care provider to identify the difference in order to provide appropriate medical management. The signs and symptoms of Acute Exudative Tonsillitis such as sorethroat, fever, pain, tonsillar erythema and edema, lymphadenitis are due to the release of inflammatory cytokines by the pathogen invasion. Inflammatory cytokines cause increased vascular permeability and leakage of protein and fluid into the surrounding tissues resulting to tonsillar edema. In addition, cellular injury and hemolysis causing erythema, release of pyrogens resulting to fever, and increase in lymph drainage into regional lymph nodes leading to cervical lymphadenitis, simultaneously occur. The findings of yellowish exudates can be explained by the cytokine mediated leucocyte activation, infiltration, and opsonization of the pathogen at the tonsillar site resulting to accumulation of cellular debris and byproducts of the inflammatory response (Marchak, 2008). The presence of otalgia (ear pain) in a patient with Acute Tonsillitis but with no evidence of ear infection is often considered a referred pain due to the involvement of the Jacobson’s nerve, a derivative of the glossopharyngeal nerve (CN IX). Cranial nerve IX provides sensory innervation to the oropharynx, middle ear, eustachian tube, posterior third of the tongue, the carotid body and sinus. According to a study conducted by Z. Abd-Alkader Taboo and M. Buraa on the etiology of otalgia, referred otalgia may be experienced when there is presence of inflammatory lesions of the palatine tonsils, nasopharynx, soft palate or the posterior third of the tongue due to the involvement of the sensory arm of the glossopharyngeal nerve (Taboo and Buraa, 2013).
