16. Treatment Viral: supportive measures (e.g. warm compresses, oral NSAIDs) Viral: supportive measures (e.g. warm compresses, oral NSAIDs) Bacterial: oral Cephalosporin such as Keflex Bacterial: oral Cephalosporin such as Keflex Inflammatory: treat underlying disease Inflammatory: treat underlying disease Consider biopsy if refractory to treatment of underlying disease Consider biopsy if refractory to treatment of underlying disease

17. Research Retrospective case series Retrospective case series 8 patients with IgG-4 related disease of salivary and lacrimal glands 8 patients with IgG-4 related disease of salivary and lacrimal glands Performed EBV FISH analysis on biopsied tissues Performed EBV FISH analysis on biopsied tissues Found a positive correlation Found a positive correlation between IgG-4 concentrations between IgG-4 concentrations and EBV load and EBV load EBV viral load may have EBV viral load may have prognostic value in these pts prognostic value in these pts
