Bone-anchored hearing aids provide significant benefits over other types of hearing aid, both audiologically and in terms of quality of life. Careful selection of candidates and meticulous follow up are required in order to minimize complications.
Although the application of a topical local anaesthetic before fibreoptic nasendoscopy is routine practice in many otolaryngological outpatients, the actual benefit to the patient of this procedure remains in doubt. Eighty-two patients were recruited in this double-blind randomized control trial which compared the patients' experiences of fibreoptic nasendoscopy with nasal preparations of Xylocaine (lidocaine), normal saline, and no spray to the nose and throat. A visual analogue scoring system was used to determine scores for the overall unpleasantness of procedure, receiving a spray, and taste of the spray, and pain. This study has shown significantly worse overall experience (P = 0.001) and pain (P = 0.048) scores for Xylocaine spray versus no spray. It is concluded that the routine use of topical local anaesthetics within the nose before routine fibreoptic nasendoscopy is not only of no value, but actually makes the experience worse for the patient.
Malignant otitis externa is a necrotising infection of the external ear canal which may spread to include the mastoid and petrous parts of the temporal bone, leading to skull base osteomyelitis. It is almost exclusively caused by infection with Pseudomonas aeruginosa, and usually occurs in elderly non-insulin-dependent diabetic patients. However isolated cases have been reported in a small number of non-diabetic patients, particularly in children who are immunocompromised due to malignancy, malnutrition and severe anaemia. In 1984 a case of malignant otitis externa was reported in a child with an acquired immunodeficiency syndrome (AIDS)-like illness, prior to identification of the human immunodeficiency virus (HIV). Since that time further sporadic cases of this invasive infection have been reported in HIV and AIDS. We present two further cases and also a review of the current literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
