RESUMEN
The aim of our study is to evaluate the relationship between diet and cancer development. It has been estimated that 30-40% of all kinds of cancer can be prevented with a healthy lifestyle and dietary measures. A low use of fibres, the intake of red meat and an imbalance of Omega-3 and Omega-6 fats may contribute to increase the risk of cancer. On the other hand, the assumption of lots of fruit and vegetables may lower the risk of cancer. Protective elements in a cancer-preventive diet include selenium, folic acid, vitamin B12, vitamin D, chlorophyll and antioxidants such as carotenoids (alpha-carotene, beta-carotene, lycopene, lutein, cryptoxanthin). Ascorbic acid has limited benefits if taken orally, but it effective through intravenous injection. A supplementary use of oral digestive enzymes and probiotics is also an anticancer dietary measure. A diet drawn up according to the proposed guidelines could decrease the incidence of breast, colon-rectal, prostate and bronchogenic cancer.

The aim of this study was to evaluate the diagnostic role and therapeutic effectiveness of videothoracoscopy in chest trauma. Between 1st January 1993 and 30th September 2003, 112 traumatized patients underwent a videothoracoscopy. The origin of trauma was different: 60 road accidents, 42 accidental falls, 7 knife wounds and 3 firearm wounds. Seventy-six patients presented hemothorax, 21 hemopneumothorax, 10 suspected diaphragmatic injury and 5 pericardium effusion. All patients were hemodynamically stable and conscious. In suspected diaphragmatic rupture patients, videothoracoscopy confirmed the presence of 4 lesions with diameter from 7 to 10cm. The etiopathogenetic causes in the other clinical patterns were: 20 lung lacerations, 17 apical adhesion lacerations, 11 diaphragmatic lesions, 16 wall bleedings and 38 vessel lesions. Ninety patients (80.3%) were treated with video assisted thoracic surgery. The remaining procedures were : 17 drainage tube insertions, 4 thoracotomies and 1 laparotomy. Videothoracoscopy made the use of the primary intention drainage tube obsolete in stable traumatized patients with hemothorax or hemopneumothorax. It is a safe technique that allows the diagnostic and surgical management of the lesions.
