During the course of a year, there are many healthcare workers nationwide who sustain sharps injuries whilst carrying out their duties. Staff who work in the Accident and Emergency (A & E) units are no different from anyone else in this respect. The emotional cost of such an accident cannot be calculated, whereas the financial costs can. This article aims to show how the cost of an injury to a member of staff can be calculated, thus allowing a manager to assess the financial implications of sharps injuries to their department. In the absence of access to an Occupational Health (OH) department, most A & E units have to respond to sharps injuries to healthcare workers in the hospital. This task must be attended to by the medical staff as well as the nursing staff of the A & E unit. Within the following text the appropriate responses and methods to ensure uniformity of response are discussed. The tables and the calculation figures shown are taken directly from the information held in the St James's University Hospital Trust's OH department. All calculations are based on the middle band of the salary scale for each discipline. Accurate costings for each member of staff injured cannot be shown in this article, but the general principle is laid down and can be easily followed for any situation.  相似文献

Rats, Man . . .     
Comments on the article by Richter entitled "Rats, Man, and the Welfare State" (see record 1960-02810-001). The commenter notes that in his article Richter did not indicate how hereditary and environmental factors were controlled. In comparing the hereditary survival characteristics of wild versus domesticated rats, it would be essential that the environmental influences on the survival characteristics of the wild rats should be ruled out. Another factor to be considered is that the wild state may offer a diet and other environmental influences, which in the life of a single individual would produce organic changes, accounting for some of the differences between wild and domestic rats. It would seem that the most effective way to determine the hereditary differences between wild and domestic rats would be to create a wild group, composed solely of the offspring of wild rats.

The concept of blood-brain barrier (bbb) arose in the beginning of the 20th century after report that the dyes injected intravenously did not appear in the brain. The idea and definition of bbb has been changed many times since then. We present current opinion concerning bbb, its histology, embryology, ultrastructure and function on the ground of a review of the recent literature.  相似文献
