[Metallic stents for acute colonic obstruction].

The traditional treatment of acute colonic obstruction, usually caused by malignant tumor, is a 2-stage surgical procedure. The first operation is emergent and includes primary tumor resection and end colostomy followed by scheduled colostomy closure. These operations are associated with high mortality and morbidity. Recently, insertion of self-expanding metallic stents for temporary colonic decompression has been was introduced. With this new technique colostomy can be avoided in the acute phase. In advanced colonic cancer stent-insertion is the only palliative treatment. It is done in the radiology department under fluoroscopic guidance. We present 2 cases of malignant colonic obstruction treated successfully by stent insertion.

Effect of turbine dental drill noise on dentists' hearing.

The effect of high-speed dental turbines on dentists' hearing was investigated. The two types of dental turbines used most commonly in the Tel Aviv area and their average time of daily use were established by means of questionnaires. The noise pressure level of these turbines at a distance of 30.0 cm was measured. Twenty subjects were exposed to the turbine noise for a period equal to the average time of the drill's daily use. The noise pressure levels of the turbines were found to be nonhazardous by the accepted damage-risk criteria. The temporary threshold shifts of the subjects exposed were nil or insignificant. It was concluded that the risk of damage to the dentist's hearing due to dental turbine noise in the normal course of a working day is slight.
