摘要:

As polyunsaturated fatty acids have better antibacterial properties than saturated fatty acids, the cerumen of seven patients with recurrent otitis externa and seven unaffected subjects was analysed to determine their ratio. There was no significant difference in either the overall ratio of unsaturated/saturated fatty acids or in the amounts of the individual fatty acids from the cerumen of either group.

摘要:

This study was designed to investigate whether patients with a conductive hearing impairment derive more benefit from the provision of a hearing aid than comparable individuals with a sensorineural hearing impairment. A secondary aim was to assess the relative hearing disability of those with each type of impairment. Twenty‐eight patients with a bilateral, symmetrical conductive impairment were selected. They were matched for age, sex and speech frequency average to individuals with a bilateral, symmetrical sensorineural hearing impairment. Each patient performed free‐field audio and audio‐visual tests in noise, both with and without a hearing aid, during which the non‐test ear was acoustically occluded. When unaided, individuals with a conductive impairment were more disabled than those with a sensorineural impairment. On the other hand, those with a conductive impairment derived more benefit from an aid than those with a sensorineureal imp

摘要:

A personal series of 765 previously untreated patients with laryngeal carcinoma seen between 1962 and 1988 was analysed for the importance of prognostic factors. There were numerous significant correlations between tumour prognostic factors, particularly with neck node status. Palpable cervical nodes increased in frequency with increasing T status, and palpable lymph nodes were commoner in less well differentiated tumours, and in supra and sub‐glottic tumours. These correlations were very highly significant. Increasing T stage was associated with increasing N stage. T stage was also associated with site, glottic tumours being far more likely to be T1than supra or sub‐glottic tumours. T stage was not related to histological grade. Histological grade correlated with site, glottic tumours being well differentiated much more often. When survival was analysed by univariate methods there were highly significant differences with increasing T stage and N stage, between the various histological grades and the various sites. However, when survival was analysed by multifactorial methods taking interactions into account, only N status was a significant prognostic factor. When patients with palpable nodes submitted to surgery were analysed, it transpired that clinical staging and node level were relatively unimportant compared with pathological findings: both the number of nodes invaded and the presence of tumour outside lymph nodes (extracapsular rupture) were highly signific
