[Incidence of peptic ulcers accompanied by gastrointestinal bleeding after surgery for critical lower limb ischemia].

Objective: To study the incidence of peptic ulcers accompanied by gastrointestinal bleeding after surgery for critical lower limb ischemia and their relationship with the factors predisposing to mucous membrane damage.

Material And Methods: The study involved 94 patients with critical lower limb ischemia who were eligible for open bypass surgery. All patients underwent preoperative gastro- and duodenoscopy.

[Contemporary data on efficacy of anticoagulant therapy in recanalization of deep veins].

The article is a literature review containing a detailed description of anticoagulant therapy variants, their efficacy in recanalization of deep veins, as well as patients' compliance to treatment. Russian specialists have demonstrated that the processes of active re-organization of thrombotic masses, in some cases leading to complete clearing of the vessel's lumen from a thrombus, may be observed at terms from 3 to 6 months, with a failure to occur within the above period reportedly followed by formation of irreversible cicatricial-sclerotic alterations in the veins. That is why adequate anticoagulant therapy should be initiated promptly in order to prevent the development of irreversible alterations and a decompensated form of chronic venous insufficiency.

[The first episode of spontaneous pneumothorax (errors, hazards, complications)].

Aim: To analyze the errors and complications of surgical care in patients with the first episode of spontaneous pneumothorax at different hospitals.

Material And Methods: From 2005 to 2015 three hundreds and seventeen patients with the first episode of spontaneous pneumothorax have been treated at the thoracic department of Volgograd State Medical University. Patients were divided into 2 groups: 79 of them underwent thoracotomy while in 238 cases minimally invasive technologies were applied.

Spontaneous and mitogen-induced cytokine production in lymphoproliferative diseases.

The levels of spontaneous and mitogen-induced production of pro- and anti-inflammatory cytokines were studied in patients with chronic lymphoid leukemia, non-Hodgkin's lymphocytic lymphomas, and multiple myeloma during the course of chemotherapy. Cytokine concentrations varied within a great range and did not conform to the normal distribution law. The levels of granulocyte and granulocyte-macrophage CSF were high during the debut, progress, and remission of the lymphoproliferative diseases.
