Parotitis is an inflammation of one or both parotid glands, the major salivary glands located on either side of the face, in humans. The parotid gland is the salivary gland most commonly affected by inflammation. Etymology
From Greek παρωτῖτις (νόσος), parōtĩtis (nósos) : (disease of the) parotid gland < παρωτίς (stem παρωτιδ-) : (gland) behind the ear < παρά - pará : behind, and οὖς - ous (stem ὠτ-, ōt-) : ear. Causes
Dehydration
Dehydration:
This is a common, non-infectious cause of parotitis. It may occur in elderly or after surgery. Infectious parotitis
Acute bacterial parotitis:
is most often caused by a bacterial infection of Staphylococcus aureus but may be caused by any commensal bacteria. Parotitis presents as swelling at the angle of the jaw. Bacterial parotitis presents as a unilateral swelling, where the gland is swollen and tender and usually produces pus at the Stensens duct. This pus is usually sampled and the bacteria within are identified. Common causative bacteria are Staphylococcus aureus, Streptococcus pyogenes and E coli. It is associated with poor oral hygiene; oral infections and decreased saliva production. Symptoms include fever, dehydration, chills, fast heartbeat and breathing if the infection is causing sepsis. Medications such as antihistamines and diuretics can be predisposing factors. Treatment is usually antibiotics.Parotitis as extrapulmonary tuberculosis:
The mycobacterium that cause tuberculosis can also cause parotid infection. Parotid swelling can be an uncommon symptom of extrapulmonary tuberculosis (TB outside of the lungs). The usual symptoms are a cough, fever, weight loss, shortness of breath, chest pain, tiredness and chills.
