Investigation of Staphylococcus lugdunensis and Selected Coagulase Negative Staphylococci Isolated from Blood Culture bottles and Determination of their Sensitivities to Antibiotics.

Objectives: Coagulase-negative staphylococci (CNS) are commensal skin microbiota but may also cause septicemia, endocarditis, and systemic infections. , is a member of CNS, but their antibiotic susceptibility test should be evaluated as not as CNS. We aimed to investigate and selected CNS strains by simple biochemical method and determination of their susceptibilities to antibiotics.

Materials And Methods: A prospective randomized trial was conducted, which included 210 patients with H. pylori - associated gastric/duodenal ulcer without complications.

[Diagnosis of incompetent communicating veins in contrast medium-sensitive patients].

A new functional method of phlebotonometry was used by the authors in 36 contrast--sensitive patient with postthrombophlebitic syndrome and varicosis for the purpose of diagnosing incompetent calf communicants. The determination of venous pressure in the superficial veins in these patients should be carried out between tourniquets three times at rest and against the backgrounds of the Valdman's test with the patient in a horizontal position by means of Valdman apparatus with elongated capillary tubes.

[Complications in surgical treatment of varicose veins of the lower limbs and their prevention].

To prevent hemorrhage and hematomas in the bed of subcutaneously removed large saphenous vein after Babcock the authors somewhat modified tactically the order of manipulations during the operative procedure. This method was employed while operating 42 patients with primary and secondary venous varices. It was feasible to prevent hemorrhage and hematomas along the vascular bed in every case.
