ABSTRACT
Ultrasound examination and laser autofluorescent spectroscopy were used intraoperatively for evaluation of gastric cancer dissemination. These methods were efficient in differentiation of cancer and benign tumors, estimation of cancer dissemination, revealing of metastases in the liver and lymph nodes. The use of these methods made it possible to increase sensitivity and specificity of estimation of cancer infiltration to 100% and of revealing lymph nodes metastases to 90% and 76%, respectively.

A study of the injury fatality rate in an adult population was done in the Moscow region. Investigators determined that side by side with the severity of injury, the direct causes of death were erroneous diagnosis, ungrounded delay of surgical interventions, and lack of and insufficient use of necessary medical care. They also showed that the attention of administrative and public health agencies to the material/technical equipment of prehospital and hospital medical service, and to the training of medical personnel, was insufficient and that activity on accident prevention was inadequate. Determination of causes will help to create concrete measures to decrease injury fatality.
