May have acute onset and may have a history of repeated episodes. 4. Recurrent painful swellings – indicative of chronic recurrent sialadenitis, may have similar signs and symptoms to an acute episode. 5. Pus exudation from salivary gland openings – indicative of bacterial infection, may occur on manipulation of the affected gland or spontaneously. Other common diagnostic factors to consider
1. Episodic swelling during meal times – may present as an acute salivary gland swelling without visible salivary flow from ductal openings. While palpation of affected glad may reveal an indurated salivary gland and presence of a sialolith. 2. Use of xerostomic medications – these medications will result in a decreased salivary flow rate which can predispose to infections of glands. Examples of medications that may contribute to this include antihistamines, antidepressant, and anticholinergic agents. 3. Recent surgical intervention under general anaesthetic – this could predispose to sialadenitis due to direct effects of anaesthetic agents used and volume depletion from surgery. 4. Dry eyes and mouth – dryness affecting the eyes and oral cavity are key symptoms of Sjogren’s syndrome and may be seen in combination with a connective tissue disease such as rheumatoid arthritis, scleroderma, or dermatomyositis. 5. Oral candidiasis – may be present in cases of Sjogren’s syndrome or in associate with a connective tissue disorder. Key factors to also consider which are less common
1. Mandibular trismus – restricted mouth opening to its full extent (of approximately 40mm) may be present with large swellings typically due to acute bacterial infection of affected gland. 2.
Treatment
Up until the advent of modern therapies, favus was widespread worldwide; prior to Schönleins recognition of it as a fungal disease, it was frequently confused with Hansens disease, better known as leprosy, and affected Europeans were sometimes committed to leprosaria. Today, due to this species high susceptibility to the antifungal drug griseofulvin, it has been eliminated from most parts of the world except rural central Asia and scattered rural areas of Africa. It is mainly a disease connected to demographic poverty and isolation, but is so readily treatable that it is among the diseases most likely to be eliminated by modern medicine. References
