[Predicting the probable passage of common bile duct calculi in patients with mechanical jaundice].

The authors propose a mathematical method of predictingthe passage of common bile duct calculi. An original mathematical formula derived by a computer allows a 98% accuracy of the prognosis. The estimations were based on the principal parameters influencingthe choledochal calculi movement defined with the help of the regression analysis. Such prediction simplifies the choice of therapeutic policy in mechanical jaundice due to choledocholithiasis.

[Predicting the duration of functioning of iliac artery prostheses].

A formula has been computer-derived to predict the duration of the operation of lavsan vascular prostheses, implanted in the iliac artery. The relative mean-square prognostic error is 2.8%. The formula outlines more specific indications for the implantation of iliac arterial prostheses.

[Predicting early postoperative thrombosis of vascular prostheses in aorto-femoral position].

Twenty nine factors influencing the function of vascular prostheses were studied in 100 patients. Five parameters were found by computation allowing the formula for prognosis of early thrombotic complications to be built in patients after reconstructive operations of aorto-femoral prostheses. These parameters are: resistance of the distal vascular bed to blood flow, length and diameter of the profound femoral artery, length and diameter of the vascular prosthesis. The accuracy of prognosis was 92%.

[Expert criteria of the degree of severity of the chemical trauma in acute poisonings by organophosphate insecticides].

The article deals with quantitative assessment of severity of chemical trauma (according to life-threatening characteristics) in case of acute peroral poisoning with OPI (carbophos and chlorophos). Standard diagrams were plotted which help to assess the life threatening values of the given compounds depending on the initial blood poison level or recorded decrease in enzyme cholinesterase activity. Basic opportunity to assess severity of body lesions in case of poisoning with OPI according to character of specific clinical signs was evidenced.
