When you go to a doctor complaining of a sore throat he might say that you have strep throat or that you have tonsillitis.

Tonsillitis

Tonsillitis is inflammation of tonsils. Tonsils are lumps on either side of the throat which are collections of lymphoid tissues. Anatomy of the tonsils is simple. It has an outer fibrous capsule which surrounds a collection of lymphoid follicles. There are four types of tonsils in humans. They are adenoids (pharyngeal tonsils), tubal tonsils, palatine tonsils, and lingual tonsils. Adenoids are located on the roof of the throat and are incompletely encapsulated. It does not have crypts. Tubal tonsils are also located on the roof of the throat. Palatine tonsils are located on either side of the throat. They are incompletely encapsulated and contain long, branching crypts on them. Lingual tonsils are located behind the tongue. They are also incompletely encapsulated, and the crypts on the surface do not branch. The lining of the tonsils differs from site to site. Underneath the capsule, there are numerous lymphoid follicles that contain T and B lymphocytes arranged in a distinct pattern. Lymph vessels draining the area around the mouth travel to tonsils. Therefore, an infection in this area will inflame the tonsils. Tonsils are supplied by nearby arteries. Inflammation of tonsils is a very common condition. It may be viral or bacterial. The patient shows symptoms of sore throat, painful swallowing, fever and ill health.

Tonsillitis can get complicated with peri tonsillar abscess formation and tonsillolith formation. Bacterial tonsillitis can have secondary complication involving the kidneys, heart, joints, skin, and central nervous system. Examination of the throat is almost always enough to make a diagnosis. While empirically antibiotics can be prescribed, it is always better getting a throat swab for culture and antibiotic sensitivity testing. Ancillary investigations like full blood count, ESR and CRP, ASOT, Anti DNAse B titer may be done as needed. Non-Steroidal anti-inflammatory drugs, acetaminophen, and antibiotics make up the treatment regimen. Follow up is necessary and chronic, recurrent or severe tonsillitis may need tonsillectomy.

Antibiotics should be prescribed and continued for the full duration. Partial treatment increases the chance of recurrences and post streptococcal complications.
