Nasal resistances were measured before, during and after the application of pressure either regionally or by lateral recumbency. In some experiments an attempt was made to block the response by local anesthetic injection, splinting the nasal vestibules, or topical decongestants. In others an electric blanket was employed as a stimulus instead of pressure. It was concluded that the nasal resistance changes during lateral recumbency are due to pressure receptors in the pelvic and pectoral girdles, and thorax. These adapt slowly. They are probably situated in the intercostal spaces, parietal pleura, or sterno-costal joints. Their centripetal fibers probably travel in the intercostal nerves, and their efferents in the cervical sympathetic outflow to the nasal erectile tissue. Lateral recumbency of 12 minutes' duration induces changes in nasal resistance which persist after the pressure asymmetry has been terminated. This may be due to temporal summation.</p>","PeriodicalId":76657,"journal":{"name":"The Journal of otolaryngology.

Frequency-specific BERA in infants. 婴儿的频率特异性贝拉。

{"title":"Frequency-specific BERA in infants.","authors":"M L Hyde","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Click BERA has several limitations, both physical and physiological, for early audiological assessment. It cannot quantify the audiometric contour, detect high or low frequency hearing loss, or reveal residual low frequency hearing. Several methods of cochlear place-specific BERA are reviewed briefly. BERA using tonepip stimuli in band-reject masking noise is described in more detail for both nil-risk and at-risk infants. Technical and normative problems are outlined. Most babies give clear ABRs to 40 dBnHL tonepips, but threshold distributions are broader at 500 Hz than for higher frequency tonepips or clicks. Thresholds improve over the first four months, especially at 500 Hz. Cases of click/tonepip threshold differences are presented. Place-specific testing may be a useful component of early assessment. Further research is needed to determine its limitations and relevance to early management.</p>","PeriodicalId":76657,"journal":{"name":"The Journal of otolaryngology.

The particular approach taken was to select occupational groups within each industry, who had the same noise exposure for a continuous period, and on whom standard hearing tests were undertaken at regular intervals. Two methods of evaluating the audiometric data were used. The first was a cross-sectional design, in which one audiogram was analyzed for each employee. The second focused on the rate of hearing loss over time within individuals. The results confirmed previous reports that the effect of continuous noise exposure was maximal in the region of 2-6 kHz. Significant differences in hearing loss were noted across job types. Over a 10 year period the rate of loss within exposed individuals was on the average 1.5 dB per year for 4 kHz, as compared with 0.5 dB for control subjects who held office jobs. The absolute difference between hearing thresholds measured at the beginning and end of this period ranged widely from a slight improvement in hearing to losses often as great as 55 dB. In general the greatest loss occurred at 4 kHz. The number of frequencies at which there was a risk of exceeding a 25 dB fence increased with the number of years of exposure.</p>","PeriodicalId":76657,"journal":{"name":"The Journal of otolaryngology.
