Exploring the Potential of Stem Cells: A Systematic Review on Cellular Therapy for Sensorineural Hearing Loss.

Sensorineural hearing loss affects a significant portion of the global population, with its prevalence projected to rise sharply in the coming years. Most cases involve the degeneration of hair cells and spiral ganglion neurons within the inner ear, and current therapeutic options for hearing rehabilitation offer limited efficacy with variable outcomes among patients. This systematic review evaluates the existing evidence on stem cell therapy as an intervention for hearing loss, focusing on its impact on hearing restoration, quality of life, and safety.

Cerebrospinal fluid leak postnasopharyngeal swab for SARS-CoV-2 testing: A case report.

Background: Due to the SARS-CoV-2 virus pandemic and its rapid spread worldwide, an early and effective detection strategy was the nasopharyngeal reverse transcription polymerase swab tests, a procedure still performed today. A relatively safe procedure when done correctly, however, one of the rare complications reported in the literature includes a cerebrospinal fluid (CSF) leak.

Case Description: A 69-year-old female patient presented to the emergency department with clear fluid rhinorrhea, clinically diagnosed with a CSF fistula after a SARS-CoV-2 nasopharyngeal swab.
