Use of new instrumental methods in the evaluation of higher cortical functions in the diagnosis of intellectual insufficiency in children

The informative value of comprehensive psychophysiological examinations of children and adolescents who suffered from varying intellectual performance impairments was defined by using the testing computer systems "Rhythmotest", "Mnemotest", "Binatest" which may qualitatively scan cognitive and psychomotor activities in a child. Examinations are listed. The paper gives the indices showing the most significant differences between ill and healthy examinees, which may be the key points in detecting intellectual defect in a patient.     

Results of treating epithelial dysplasias of the uterine cervix with CO2-laser rays

The problem of the presence of carcinogens in the environment has become of considerable concern to the public, as it has been to the biomedical community for some time. The burden of identifying carcinogenic agents and determining threshold levels, if they exist, falls upon the scientific community. Particular care must be exercised in the design, conduct and analysis of experiments directed toward the identification of carcinogens. The data generated from such tests provides the basis for regulatory decisions by governmental authorities. The advice provided by scientists must be based on sound data. There have been instances, however, and there will be others, in which biological variability and the limits of sensitivity of our tests will give equivocal results. It is the duty of scientists to bring such uncertainties to the attention of the public while working towards the development of more sensitive and precise techniques.

The use of antioxidants together with polysorb enterosorption in the combined treatment of patients with III-IV-stage ovarian cancer

Studied in the course of a multiple-modality treatment of patients with stage III to IV ovarian cancer were effects of retinol and tocopheroli acetas and enterosorption with a silicone sorbent polysorb on the processes of lipid peroxidation and indices for the antioxidant system, for which purpose 75 female subjects were examined. The results obtained showed that retinol and tocopheroli acetas and enterosorption combined in treatment of patients with stage III-IV ovarian cancer made for stabilization of the processes of lipid peroxidation as well as for normalization of blood plasma content of factors of the antioxidant defence.     

Comminuted supracondylar humeral fractures repaired with a modified type I external skeletal fixator construct

Highly comminuted supracondylar humeral fractures were stabilised in six large-breed dogs with a modified type I external fixator using a craniomedial acrylic connecting column and an intramedullary pin which was incorporated into the connecting frame. This construct provided sufficient stability to allow satisfactory bone healing in five of the six dogs, while premature removal of the intramedullary pin and external fixator resulted in subsequent refracture of the humerus in the remaining dog. Limb function at the time of final assessment was considered excellent in two dogs, good in three dogs and poor in one dog. The craniomedial acrylic connecting column simplified application of this modified type I(a) configuration to the humerus by reducing the number of clamps required; the acrylic column also facilitated contouring of the craniomedial connecting column to the brachium and was readily extended proximally to engage the intramedullary pin. In addition, the acrylic connecting column allowed placement of intramedullary pins of varying diameter.
