[Surgery without boundaries].

Surgery at the turn of the century and at the millennium is characterised by an extremely rapid development. There are no boundaries anymore among the different branches of medicine, in different anatomical regions of the human body, between the living human and the artificial tissues, between the reality and the virtual reality. Nanotechnology and robotics offer new possibilities for minimally invasive procedures.

[Role of the monocye-lymphocye system and of endogenous mediators in the severity of acute pancreatitis and in development of its septic complications].

The activity of monocyte/lymphocyte system and the splanchnic circulation was investigated in acute pancreatitis. The splanchnic blood flow was characterised indirectly by gastric intramucosal pH changes, which strongly correlated with APACHE-II score, and predicted the bad prognosis. The high CD14/HLA-DR and CD14/CD16 coexpression, the low TNF-alpha production proved to be unfavourable prognostic factor in the early phase of the disease.

Anaesthesiological indications and contraindications of minimally invasive surgery.

Spreading of laparoscopic techniques caused changes in anaesthesiological contraindications. In the first period laparoscopy was contraindicated in ischemic heart disease (IHD). Early mobilisation and short postoperative period are positive goals, IHD was taken out of contraindications.

[One year's experience of a mammography unit (author's transl)].

3035 examinations were performed at the newly-opened Mammography Unit of the Department of Radiology, Semmelweis University, Budapest in 1976 and 1977. Most of the examined persons presented themselves voluntarily and had some kind of complaints. 153 cases of breast cancer were detected and operated.
