OHSU researchers discover toxicity risks for widely used chemicals

Research at Oregon Health & Science University (OHSU) has revealed that certain chemical ingredients of gasoline, jet fuel and other solvents may pose a greater health hazard than first thought. Scientists at the OHSU Center for Research on Occupational and Environmental Toxicology (CROET) have shown that a benzene derivative damages the nervous system. In fact, the substance is much more active than non-benzene analogs already known to cause peripheral nerve damage (loss of limb sensation and muscl

Ball to occlude the aorta during cardiopulmonary resuscitation

Jesus Manuel Labandeira in his doctoral thesis, read in the University of Navarre, tested this technique in pigs due to the similarity to the human cardiovascular system.

According to the results obtained by doctor Labandeira, the use of a occlusion ball in the aorta duplicates the blood pressure that goes to heart and brain during cardiopulmonary resuscitation.

Improving the results of CPR

Cardiopulmonary resuscitation (CPR) constitutes one of the most emble

Tamoxifen for prevention of breast cancer – encouraging results but risks still unclear

Early findings from a randomised trial investigating the effectiveness of tamoxifen to prevent breast cancer are reported in this week’s issue of THE LANCET. Although tamoxifen reduced breast cancer incidence by a third compared with women given placebo, the authors of the study caution that it is still too early to fully assess the risk to benefit ratio of tamoxifen as a preventative strategy for breast cancer.

Tamoxifen is well known in its effect to decrease recurrence of (and death from

Effect of diet on cancer risk

A review in this week’s issue of THE LANCET assesses the research which has investigated possible links between diet and cancer. A familiar conclusion is reached-cancer risk can be reduced by eating a balanced diet (including the regular consumption of fresh fruit and vegetables), combined with regular exercise and a restriction on alcohol intake.

Diet-related factors are thought to be second only to tobacco in accounting for cancer-accounting for about 30% of cancers in developed countries

Major breakthrough in treating autism

Results of a new programme for treating young children with autism have shown that even the most disabled made outstanding progress. Ninety-four percent of those completing the programme so far are now able to attend a mainstream school.

The South West Autism Project (SWAP), directed by Professor Alec Webster of Bristol University and funded by Bristol City Council, was started in September 2000, following a marked rise in the number of children in Bristol being diagnosed with autism. Data f

Study finds outbreak of Cipro web sites followed anthrax outbreak

Web sites selling the prescription-only medication ciprofloxacin (also known by its brand name Cipro®) sprang up quickly following an anthrax outbreak in October 2001, according to a new study by researchers from the Case Western Reserve University (CWRU) School of Medicine. The study, published today in the American Journal of Medicine, also found that these Web sites provided poor quality information, had inadequate consumer safeguards, and charged high prices.
