The middle ears of 29 male Sprague-Dawley rats were injected with viable pneumococci, type 3 or 6A, and changes were monitored by otomicroscopy and analysis of bacterial samples from middle ear effusions, blood, and the nasopharynx. Depending on the type of pneumococci and its concentration, three responses were noted: otitis media with purulent effusion,(More)
Rat middle ear was exposed to challenge with viable pneumococci, type 3 and 6A, and the course of changes in the middle ear was observed by otomicroscopy and analysis of bacterial samples from blood, nasopharynx and middle ear effusions. Microscopical examination of changes in the middle ear mucosa during and after the acute infection was also made.(More)
In an animal external otitis model, inflammatory reactions were evoked by mechanical stimulation of the rat ear canal skin. The rats were in four groups: group A treated with a group III steroid, betamethasone dipropionate; group B treated with hydrocortisone combined with oxytetracycline; group C treated with hydrocortisone with oxytetracycline and(More)
The present study was undertaken to compare the clinical benefits of prescribing ear drops containing 0.05% solution of betamethasone dipropionate (BD), and ear drops containing hydrocortisone with oxytetracycline hydrochloride and polymyxin B (HCPB), for topical treatment of external otitis. Fifty-one patients were enrolled in this open randomized,(More)
Mean peak velocity and accuracy of vertical saccades were measured in 15 patients with disorders in the brain stem and in 12 normal subjects. (1) In the normal group up-directed saccades were faster than down-directed and the velocity of the saccade was not dependent on the age of the subject. Up-saccades were faster whether electro-oculography or(More)
CONCLUSIONS Irrespective of the microbial agent, group III steroid solution cured external otitis efficiently in a rat model. The addition of antibiotic components to steroid solutions for the treatment of external otitis is of questionable validity. OBJECTIVE External otitis, caused by infection with either Pseudomonas aeruginosa or Candida albicans, was(More)
External otitis was produced in 12 Sprague-Dawley rats by mechanical stimulation through a plastic micropipette inserted into the right external auditory canal (EAC). The EAC was later evaluated regarding the color of the skin, swelling and the presence of fluid. Within 1 day all rats developed an external otitis that was characterized by a red, swollen ear(More)
In this retrospective study of parotid tumours, 57 patients with pleomorphic adenomas were treated with superficial parotidectomy and 33 patients with limited excision. The follow-up period has been 4-14 years. When the operation was superficial parotidectomy, recurrences occurred in 8.7 per cent compared to 6 per cent in cases of limited excision.(More)
Hypertrophy of the inferior turbinates is a common cause of nasal obstruction. Many cases respond to medical treatment with topical steroids or antihistamines. In some patients, however, this therapy is not sufficient and through the years many surgical procedures have been used to reduce the size of the inferior turbinates, but without any satisfactory(More)
3 To Mari, for her support and love " If you repair or rebuild something, it will rarely be perfect, but it will be better than before! " My wife, Mari 4 Fig: Visual mind map Remember; Full thickness skin with adnexa and with cartilage beneath, in 2/3 of the EAC. The skin is thin and with a bony support, in the most medial part of the EAC. Channels of(More)
