[Fibrinogen determination by the Clauss method. Reagents and analyzers].

The Clauss method was recommended by the WHO to measure plasma fibrinogen levels. The purpose of this study was to assess the application of test systems made by the RENAM Research-and-Production Association (Moscow) on different types of clinical laboratory analyzers to measure fibrinogen by the Clauss method. The calibration line is shown to be of major value in obtaining correct results on each coagulometer. The findings suggest the accuracy and reproducibility of the determination of fibrinogen concentrations by the Clauss when the REHAM test systems are used to measure fibrinogen concentrations on various analyzers if accurate calibration lines are obtained.

[Surgical treatment of severe postburn flexion contractures of the hand]. / Khirurgicheskoe lechenie tiazhelykh sgibatel'nykh posleozhogovykh kontraktur kisti.

The authors discuss the surgical tactics in multiple burn contractures of the palmar surface of the hand from experience in the treatment of 45 patients. The operation is conducted in one stage, with the manipulations performed in a definite order, which makes it much easier. The operation consists in correction of adduction of the thumb and the region of flexion contractures of the metacarpophalangeal articulations, palmar syndactyly, flexion contractures of the fingers, and contractions of the palm. Plastics with trapeziform grafts in combination of the palm. Plastics with trapeziform grafts in combination with free skin grafting makes it possible to correct all contractures in one stage and restore the function of the hand.

[Protracted atypical course of enterovirus infection]. / Zatiazhnoe atipichnoe techenie zabolevanii énterovirusnoi étiologii.

Two cases are presented of replication of enteroviruses over a long period of time, that caused a protracted atypical clinical course of infection. No typical clinical markers of infection can be seen in the wake of enterovirus replication; the replication itself can be of a protracted recurrent character. Replication of enteroviruses is capable of inducing a protracted recurrent subfebrile condition in adults that has no clinical signs of immunodeficiency state. Parallel activation of replication of a number of viruses, according to our data, is a widespread phenomenon, which fact is to be taken account of in planning examination and treatment strategies. Laboratory tests are needed for the activation of diseases of enteroviral etiology to be ascertained.
