Zika in pregnancy causes deafness in infants in 6% of cases

Zika in pregnancy causes deafness in infants in 6% of cases

According to the researchers, lesions may occur in both the cochlea (in the inner ear) and in the brain, causing hearing loss. However, several other viral infections during pregnancy can cause hearing loss, including rubella and cytomegalovirus, or CMV.

Even though it is a small sample made only with babies with microcephaly, the finding serves as a warning to scientists. The Zika virus can now be considered a risk factor for hearing loss and children exposed during pregnancy, but with normal hearing, should be checked regularly to prevent progressive hearing loss.

Across the country, confirmed 1,749 cases of microcephaly and other nervous system disorders, suggestive of congenital infection. Of the total confirmed cases, 272 had laboratory confirmation for the Zika virus.

Use of antibiotics for sinusitis is recommended only in cases caused by bacteria

There is a current trend from national and international guidelines to replace the classic term sinusitis with rhinosinusitis because of the difficulty of establishing precise limits for the inflammatory processes that affect the mucosa of the nose and paranasal sinuses. The sinuses or paranasal sinuses are aerated cavities located in the anterior region of the skull that communicate with the nasal cavity through ventilation and drainage ostia (orifices).
