A makeshift blue light filter for endoscopic identification of traumatic cerebrospinal fluid leak using fluorescein

Objective@#To describe a makeshift blue light filter for endoscopic visualization of a traumatic cerebrospinal fluid leak repair using intrathecal fluorescein and its application in one patient.@*Methods@# Study Design:Surgical Instrumentation Setting:Tertiary Government Training Hospital Patient:One @*Results@#Intra-operative endoscopic identification of fistulae sites was achieved using intrathecal injection of fluorescein that fluoresced using our makeshift blue light filter in a 43-year-old man who presented with a 3-month history of rhinorrhea due to skull base fractures along with multiple facial and upper extremity fractures he sustained after a fall from a standing height of 6 feet. He underwent transnasal endoscopic repair of cerebrospinal fluid fistulae in the planum sphenoidale, clivus and sellar floor. Post-operatively, there was complete resolution of rhinorrhea with no complications noted. @*Conclusion@#Our makeshift blue light filter made from readily available materials may be useful for endoscopic identification of CSF leaks using fluorescein in a low- to middle-income country setting like ours.

Smell training in prolonged COVID-19 post-infectious olfactory dysfunction: A case report

Objective@#To report the case of a woman who underwent smell training for post-infectious olfactory dysfunction presumably from COVID-19. @*Methods@#Design: Case Report. Setting: Tertiary Private Training Hospital. Patient: One. @*Result@#A 41-year-old woman who developed olfactory dysfunction attributed to COVID-19 underwent smell training. At baseline, her responses were mostly “no smell,” and those reported as “can smell a bit” were rated as distorted. After three months, she could now smell items that she previously could not smell, but these smells were still distorted. At the time of this writing, she was on her 4th month of smell training. @*Conclusion@#Although we cannot rule out spontaneous resolution of anosmia in our patient, we would like to think that smell training contributed to her recovery of smell.
