Condition 1: Throat Pain
Pathophysiology
Throat pain, pharyngitis or sore throat is generally caused by bacterial or viral infection.
The bacteria, which is the prime reason for pharyngitis is Streptococcus pyogenes. This
bacterium has A-antigen that makes the bacteria Group A beta hemolytic streptococci. Further,
the hyaluronic acid capsule of the bacteria is also responsible for the infection. Furthermore, the
exotoxin released by the bacteria destroys the immune system of pharynx and proliferates the
infection (Renner, Mueller & Shephard, 2012).
Clinical presentation
The clinical presentation of sore throat is due to the proliferation of the bacteria within
the human body. Further, it leads to symptoms such as nausea, vomiting, lower abdomen pain
body and head ache. Clinical check-up of the adult patient determines the presence of fever,
tonsil erythema or swollen tonsillitis, swollen uvula, patchy exudates and rashes on the neck after
manifestation of the bacterium (Buttaro et al., 2012).
Diagnosis
Diagnosis of pharyngitis is done based on three aspects, physical exam, throat culture and
blood tests. Throat culture is done by collecting the swab sample of the exudates from throat.
Further, using rapid strep test kit or proper lab techniques, throat culture reports are generated. In
physical assessment, the physician checks the throat and diagnoses patches and swelling. Further
checkup involves identification of swollen lymph nodes. Blood test is performed to determine
the presence of mononucleosis in blood culture of patient (Fine, Nizet & Mandl, 2012).
