Nasal irrigation with various solutions for adults with allergic rhinitis: A protocol for systematic review and meta-analysis of randomized controlled trials.

Background: Nasal douching or irrigation has been recommended for adjunctive therapy of sinonasal diseases including allergic rhinitis (AR) for many years. Previous study reported large-volume high-pressure device as an effective standard application, but the solutions was remains controversy. This study systematically review the clinical efficacy of nasal irrigation with various solutions for adults with AR from medical literature.

Seroprevalence of IgA anti Epstein-Barr virus is high among family members of nasopharyngeal cancer patients and individuals presenting with chronic complaints in head and neck area.

Epstein-Barr (EBV) infection and presence of a nasopharyngeal cancer (NPC) case in the family increases the risk of developing NPC. Aberrant anti-EBV immunoglobulin A (IgA) antibodies (EBV-IgA) may be present in the sera of non-cancer individuals and predict NPC. Limited studies report the presence of EBV-IgA antibodies within non-cancer individuals in Indonesia where the disease is prevalent.

Epigenetic markers for early detection of nasopharyngeal carcinoma in a high risk population.

Background: Undifferentiated nasopharyngeal carcinoma (NPC) is strongly related to Epstein-Barr virus (EBV) infection, allowing aberrant antibodies against EBV and viral DNA load as screening tools in high risk populations. Methylation analysis in the promoter of tumor suppressor genes (TSGs) may serve as a complementary marker for identifying early cases. This study determined methylation status of multiple TSGs and evaluated whether it may improve early detection.
