摘要:

Technetium‐99m (99mTc) (v) dimercaptosuccinic acid (DMSA) is a new tumour‐imaging agent which has been used to image head and neck squamous carcinoma. This study used an established rabbit tumour model to compare palpation versus planar scintigraphy in the detection of superficially transplanted cancers. Palpation detected 83% of tumours measuring less than 2 cm compared with 58% for scintigraphy. Overall, the sensitivity for palpation was 88% (77% specificity) compared with 50% (63% specificity) for scintigra

摘要:

So far, the published guidelines for patient selection for the Audiant implanted bone conduction device have been derived from clinical trial rather than experimental study. Theoretical considerations suggest that the guidelines should be frequency specific; the need for this was investigated in a laboratory study. Two independent measures of the maximum output of the Audiant device using both the body‐worn and ear‐level amplifiers have been performed on two subjects. These lead to maximum output figures for the device ranging from 15 dB HL at 250 Hz to 60 dB HL at 6000 Hz for the body‐worn amplifier, and from 6 dB HL at 250 Hz to 42 dB HL at 6000 Hz for the ear‐level amplifier. These results suggest that the ear‐level amplifier is suitable only for candidates with essentially normal bone conduction thresholds at frequencies of 1000 Hz

摘要:

Prosthesis‐assisted tracheoesophageal speech has advanced speech rehabilitation appreciably. However, the surgical technique and the use of a prosthesis may give rise to complications. In a retrospective study on 132 consecutive patients rehabilitated with a Groningen button voice prosthesis, the complications were assessed, the average follow‐up being 21 months. Surgical complications were not observed. Prosthesis‐related complications, which were encountered in 28%, were all of a minor nature and mainly consisted of granulation formation and hypertrophic scarring; these appeared to be easily treatable. The complications found were few and insignificant in comparison with reports in the literature. This may be attributed to the uncomplicated surgical procedure for the insertion of the Groningen button. Moreover, the prosthesis is self‐retaining and requires hardly any care from the patient. Permanent removal of the prosthesis usually requires surgical closure, which is a simple procedure performed under local anae

摘要:

The current policy of British Otolaryngologists with regard to the preoperative cessation of the oral contraceptive pill is reported. This is based on a confidential questionnaire sent to all members of the British Association of Otolaryngologists. The overall response rate was 66%, 91% of which were from practising otolaryngologists and forms the basis of this report, the remaining 9% being from respondents not engaged in active surgery. Although there is evidence to show an increased risk of developing thromboembolic complications after major abdominal, gynaecological and hip surgery in those patients taking the oestrogen‐containing contraceptive pill, the risk following minor and intermediate surgery (which forms the bulk of the otolaryngologist's workload) is not known. Not surprisingly therefore the results of the survey show a varied policy across the country with 36.5% of respondents choosing to continue the pill and 25% always stopping the pill preoperatively. The remainder elect to stop the pill only in certain circumstance

摘要:

We describe 50 patients with anaplastic carcinoma presenting with a mass in the neck. The diagnosis of anaplastic carcinoma was confirmed by immunocytochemistry to exclude very poorly differentiated squamous carcinomas, amelanotic melanoma, and non‐Hodgkin's lymphoma. The primary site was established immediately in 26 patients (25 in the head and neck; 1 in the lung); a further 4 had radiological evidence of a primary tumour in the lung. The primary site was established later in 1 patient, in the ethmoid sinuses. In 20 patients the primary site was never established. The commonest primary site was the nasopharynx.The basic treatment policy was radiotherapy, although 20% of patients with a known primary tumour, and 50% of those without, were untreated. The 2‐year survival was about 30% in both groups, and did not differ significantly. Prognostic factors for survival were age, performance status, and T status of the primary tumour. Sex, node status, node level, and laterality of nodes, were

摘要:

Thirty‐four sets of consecutively used double gloves (68 pairs) used by otolaryngologists and their assistants in operations known to have a high risk of glove punctures were studied. The perforation rates for the outer and inner layers were 35.3 and 8.8% respectively, indicating that a second set of gloves substantially improves the likelihood of maintaining an intact barrier between medical staff and patien

摘要:

Patients with a peripheral facial palsy due to an underlyingIxodes‐borneborreliosis often have cerebrospinal fluid findings indicating meningeal involvement. The aim of the present study was to identify signs of CNS involvement by means of brain‐stem evoked response audiometry (BSER) in patients with a facial palsy due to borreliosis, as well as in patients with a facial palsy of unknown aetiology, Bell's palsy. Abnormalities in BSER were found to be significantly more common among the borrelial patients. Furthermore, a reversal of these abnormalities following treatment with benzyl‐penicillin was found in the majority of patients with borreliosis. The results of the present study emphasize the importance of diagnosing and treating an underlying borreliosis in patients with a peripheral facial

摘要:

From 1982 to 1987, 20 patients with disabling attacks of vertigo and severe hearing loss due to unilateral Meniere's disease were treated with local intratympanic gentamycin. In 18 patients control of vertiginous attacks was achieved. Hearing deteriorated in 8 patients. In spite of complete control of attacks a disabling ablation type of unsteadiness and dizziness affected 7 patients. Two patients required additional treatment after 5–8 months remission. Intratympanic gentamycin seems to be a less useful method of treating severe unilateral Meniere's disease than previously stated. It is, however, a possible alternative to surgical labyrinthectomy with a fair chance of residual hearing preservatio

摘要:

Preoperative estimation of haemoglobin in children undergoing tonsillectomy is routinely practised in most centres. To assess the value of this investigation the haemoglobin of 250 consecutive children undergoing tonsillectomy was estimated. Two children were clinically found anaemic preoperatively, and this was confirmed on blood testing. Since the prevalence of anaemia is low, it is proposed that the practice of routine preoperative estimation of haemoglobin is unnecessary, traumatic and expensive, and therefore requires reconsideration.
