Hand-arm vibration syndrome and its prevalence in the present status of private forestry enterprises in Japan

Summary Currently there are no limitations on age of employment on private forestries in Japan. Hence, it was hypothesized that in these kind of enterprises, elderly chain saw operators, or those with long-term exposure, might be at higher risk of developing hand-arm vibration syndrome (HAVS). We consequently investigated the prevalence of HAVS in 447 chain saw workers on private forestries in Gifu Prefecture, Japan, with particular reference to age and exposure period. Of this population, 43 (9.6%) had signs and symptoms of vibration-induced white finger (VWF), and among these workers the severity of finger blanching was significantly correlated (P < 0.01) with the exposure period. Classification of all subjects by exposure period showed that workers with 30 years' exposure had higher prevalences of VWF (20.9%) and numbness of the hands (25.4%) compared to other groups. Significant differences (P < 0.01) were found between the functional capacities of workers with VWF and those of control subjects. We concluded that (a) the elderly chain saw operators and those with longer exposure should be moved to other jobs with a lower or no risk of exposure to vibration, and (b) the results of screening tests, even without cold water immersion (which we did not employ, in order to protect workers' hands), could be helpful for the identification of workers with VWF.     

小切口白内障手术中后囊膜破裂一期人工晶体植入术临床疗效分析

Peritonsillar abscess – critical analysis of abscess tonsillectomy

The risk of secondary haemorrhage following abscess tonsillectomy is reported in the literature with differing rates. A retro‐ and prospective analysis of complication rates following abscess tonsillectomy was conducted in 142 patients (54 females, 88 males; mean age: 35 years). In 22% of patients, a secondary haemorrhage occurred. In half of these (11% of total), the haemorrhage had to be treated surgically. Secondary haemorrhage occurred most commonly on the 6th and 8th postoperative days. Reports in the literature are not in unison about the risk of secondary haemorrhage following abscess tonsillectomy and therefore allow no final judgement about an objective risk of this complication. This report strengthens the results of the ‘Comparative Audit Service’ analysis from 1997, which did show a high risk of secondary haemorrhage following tonsillectomy, as well as following abscess tonsillectomy.
