The nose is becoming a common route of drug administration, however, little is known about the pH of the human nasal cavity. Local pH may have a direct effect on the rate and extent of absorption of ionizable compounds and hence this study was performed to investigate normal pH values and whether pH could be manipulated by various buffers. Twelve healthy(More)
Between 1991 and 1993, 13 children (25 hearing ears) underwent recordings of the auditory brain stem response (ABR) under a general anaesthetic. The anaesthetic technique was similar for each child. Fourteen of these ears had fluid aspirated after myringotomy with insertion of grommets prior to the auditory brain stem response investigation. On subsequent(More)
In these studies, we examined the effect on mucociliary transport rates (MTR) of various 0.25% (w/v) chitosan solutions applied to human nasal tissue both ex vivo and in vivo. In the first study a range of chitosans with different molecular weights were applied to freshly amputated human nasal turbinates, and their effect on MTR was recorded. The transient(More)
The aim of this study was to assess whether client centred hypnotherapy (CCH) which required three sessions with a trained therapist was superior to a single counselling session in reducing the impact of tinnitus. Patients were randomly allocated to receive either counselling (n = 42) or CCH (n = 44). The outcome measures were: tinnitus loudness match,(More)
The mucociliary transport rate was measured using sequential images of graphite particles moving on 17 isolated human inferior turbinates. These had been removed from 13 patients who had normal saccharin clearance tests on the day of surgery. The initial mean mucociliary transport rate was found to be 4.1 mm/min rising to 5.0 mm/min 2 h after harvesting.(More)
In this study we prospectively analyzed 41 patients, 15 females and 26 males with a mean age of 54, who underwent three sessions of client-centered hypnotherapy for their tinnitus. Of these patients, 28 (68%) showed some benefit for their tinnitus 3 months after completing their hypnosis, and 13 (32%) showed no evidence of improvement for their tinnitus.(More)
