Morphological estimation of changes in cancellous raduis bone for forensic age determination

Visual researches showed that the cancellous bone of the distal radius has significant morphological changes with the increase of years. Revealed structural changes of cancellous bone allows to differentiate the age of an object and to direct a medical expert towards the proposed age group at the identification study. As a result of photocolorimetric research of involution changes of cancellous bone of the distal radius we found statistically significant increase of light transmission with the increase of years which is associated with an increase of osteoporosis. The correlation coefficient ranged from 0,63 to 0,80. On the basis of these data mathematical models that allow to determine the person's age in the forensic identification researches of the distal radius were developed (standard mean square error in determination of the age was from 6,6 to 8,2 years)

Extracorporal modified ascitic fluid reinfusion in treatment of resistant ascites in liver cirrhosis

OBJECTIVE. The aim of the study was to estimate the efficacy of new method of reinfusion of extracorporeal modified ascitic fluid in therapy of diuretic resistance ascites in patients with liver cirrhosis and portal hypertension syndrome. MATERIAL AND METHODS. An analysis of treatment was made in 83 patients, who underwent laparocentesis and ascitic fluid evacuation. The patients were divided into two groups. Laparocentesis and fractional evacuation of ascitic fluid were carried out for the patients of the first group (n=40). This procedure was followed by intravenous infusion of 25 % albumin (10 g of albumin on each 2 litres of removed fluid) in order to make up losses of protein. Laparocentesis and ascitic fluid evacuation with following extracorporal processing and reinfusion were performed for the second group of patients (n=43). RESULTS. There was noted an increase of day diuresis from (620,0 ± 110,0) ml to (2,2 ± 0,4) l compared with the first group from (780 ± 80) ml to (1,2 ± 0,5) l and rise of sodium excretion (132 ± 7) mmol/l compared with the first group - (120 ± 6) mmol/l. An average molecular peptide concentration was decreased in blood plasma to (0,254 ± 0,098) units in the second group and it counted (0,298 ± 0,045) units in the first group. CONCLUSIONS. Reinfusion of extracorporeal modified ascitic fluid was more effective than conventional correction of albumin level and electrolytes disturbances against a background of ascitic fluid evacuation

Three-dimensional (3D) model-based lower limb stump automatic orientation

© 2020 by the authors. Modern prosthetics largely relies upon visual data processing and implementation technologies such as 3D scanning, mathematical modeling, computer-aided design (CAD) tools, and 3D-printing during all stages from design to fabrication. Despite the intensive advancement of these technologies, once the prosthetic socket model is obtained by 3D scanning, its appropriate orientation and positioning remain largely the responsibility of an expert requiring substantial manual effort. In this paper, an automated orientation algorithm based on the adjustment of the 3D-model virtual anatomical axis of the tibia along with the vertical axis of the rectangular coordinates in three-dimensional space is proposed. The suggested algorithm is implemented, tested for performance and experimentally validated by explicit comparisons against an expert assessment
