1. 1. Time-related Aspects of Otoprotection : Experimental Studies in Rat

   Författare :Adnan Lidian; Matti Anniko; Petri Olivius; Uppsala universitet; []
   Nyckelord :sensorineural hearing loss; Edaravone; brain-derived neurotrophic factor; auditory brainstem response; Sprague-Dawley rat; distortion product otoacoustic emission; Pseudomonas aeruginosa exotoxin A.; Oto-Rhino-Laryngology; Oto-rhino-laryngologi;

   Sammanfattning : Intratympanic injection of various otoprotectants through the round window membrane (RWM) might become available in the near future as an alternative to the currently available medical and surgical methods used to treat several inner ear diseases. The most common outcome of such diseases is sensorineural hearing loss (SNHL). LÄS MER

3. 2. Effects of iron supplementation on iron status, health and neurological development in marginally low birth weight infants

   Sammanfattning : Background Due to small iron stores and rapid growth during the first months of life, infants with low birth weight (LBW) are at risk of iron deficiency (ID). ID in infancy is associated with irreversible impaired neurodevelopment. LÄS MER

4. 3. The Round Window Membrane - Gateway to the Cochlea : A Morphological and Electrophysiological study

   Författare :Leif Nordang; Sten Hellström; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; round window membrane; pseudomonas exotoxin; auditory brainstem response; hearing loss; endolymphatic sac; inner ear immunology; glutamate; nitric oxide inhibitor; glucocorticoid.; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

   Sammanfattning : Topical treatment of several inner ear diseases through the round window membrane (RWM) might be feasible in the near future. Bacteria toxins, ototoxic drugs and noise trauma seem to harm the inner ear by a common pathway which involves, excessive outflow of the afferent neurotransmitter glutamate and formation of nitric oxide (NO), which can severely damage cells/nerve endings and lead to cell death.

5. 4. Topical anesthesia of the tympanic membrane : an experimental animal study

   Författare :Sten-Hermann Schmidt; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Topical anesthesia; middle ear; tympanic membrane; cochlea; collagen fibres; lidocaine; 96 % phenol; Bonain s liquid; auditory brainstem response; ototoxicity; cytocochleogram; scanning electron microscopy; rat; guinea pig;

   Sammanfattning : Myringotomy plays an important role in otological therapy. The procedure requires an efficient anesthesia, which can be obtained without general anesthesia. However, the use of local anesthetics on the tympanic membrane (TM) has been abandoned in many places, as general anesthesia has been readily available. LÄS MER

7. 5. Drug-based therapies for auditory trauma

   Författare :Anette Fransson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Deafness is one of the most common health conditions in the developed countries, and worldwide, an estimated 70 million people are deaf. For people with severe to profound hearing loss, a cochlear implant is the only treatment today. The most common forms of severe hearing loss and deafness are related to morphological changes in the cochlea. LÄS MER
