Aetiology, Diagnosis, and Treatment of Paraesthesiae in the Hands

Abstract

CATARACT SURGERY BRouTLS 1633 to occur when using alpha-chymotrypsin but that this increase may be due to the slight increase in mechanical intervention. There seemed to be a slightly higher percentage of cases showing increased opacities in the vitreous in this series than in our previous cases. We feel that the difference was not great enough for us to draw a definite conclusion. There was no increase in the amount of the opacities in any case during the follow-up period.In our series the vitreous face was carefully inspected ovei a period of a year. The appearances were compared with earlier cases of our own and with the descriptions and statistics of previous authors relating to uncomplicated intracapsular extractions without the enzyme.We believe that there is no greater tendency either to bulging forward of the vitreous face or to the appearance of rents and tears in the anterior hyaloid membrane when alpha-chymotrypsin is used.There was no tendency towards deterioration in the vitreous face during the 12 months of the study.Our thanks are due to the nursing and clerical staff of the Croydon Eye Unit for their assistance, and in particular to Mrs. S. Tant, medical secretary.

Occupational factors and carpal tunnel syndrome

“…Contrary to most clinical and field study reports [Tamer, 1959;Kendall, 1960;Phalen, 1972;Swajian, 1981;Mathur, 1981;Cannon et al, 19811, there was no difference in prevalence of CTS between females and males. This may be due to employee selection into different types of jobs on the basis of gender (females in high repetitive jobs and males in high force jobs).…”

Median sensory distal amplitude and latency: Comparisons between nonexposed managerial/professional employees and industrial workers

“…If the findings represent effects caused by local compression, then the lack of a difference in median motor amplitude between the populations is consistent with the greater resistance of motor (compared to sensory) fibers to the effects of acute local compression and ischemia [Lundborg et al, 19821. Reports from case series of patients with CTS support a similar finding with chronic compression: thenar muscle weakness and wasting (i.e., signs of severe median motor nerve dysfunction) were almost always preceded by hypesthesia or paresthesia which had been present for many months to years [Kendall, 1960;Phalen, 19661. Although longer latencies could have been associated with the cooler skin temperatures in the industrial population, temperature was controlled for when performing covariance analyses. Furthermore, amplitudes are negatively associated with temperature [Denys, 19801 and, thus, would have been smaller among the control population if temperature were the critical differentiating factor.…”

The association of Raynaud’s syndrome with carpal tunnel syndrome: a meta-analysis

“…Again, the estimated prevalence increased when the year of commencement increased, too. One possible reason for these findings could be the fact that Kendal [26] published early with a low prevalence and a large study population. On the other hand, Pal et al [5] published late and determined a high prevalence and a large study population, too.…”
