Sudden deafness as an initial presentation of varicella: case report and literature review.

Varicella, or chickenpox, is a highly contagious disease transmitted by the varicella zoster virus (VZV). Idiopathic sudden sensorineural hearing loss (ISSNHL) has been defined as a loss of at least 30 dB over at least three frequencies on audiogram within three days and with an uncertain cause. Deafness caused by varicella-zoster virus occasionally occurred in Ramsey hunter syndrome but associated with chickenpox is rare.

Correlation between serum lipid and prognosis of idiopathic sudden sensorineural hearing loss: a prospective cohort study.

Background: To investigate the correlation between blood lipids and the prognosis of idiopathic sudden sensorineural hearing loss (ISSNHL).

Methods: We included 232 patients with ISSNHL at the Second Affiliated Hospital of Shanghai University from June 2015 to March 2017 using a prospective cohort study design. We collected information including age, gender, hypertension, diabetes, mellitus, vertigo, as well as the levels of blood total cholesterol (TC), triglycerides (TG), and low-density lipoproteins (LDL-C).
