Risk of fatal postoperative pulmonary embolism in cancer patients

A retrospective study included 100 cancer patients who had died of fatal pulmonary embolism (PE) in the postoperative period. Assessment of the hazard of fatal postoperative PE demonstrated that the risk peaked on day 7 after operation and later on gradually diminished. The first three postoperative weeks featured high risk of fatal PE development as 90% of deaths were registered during its course.     

Current approaches to the treatment of non-gonococcal urethritis in men

The study was made of 50 men suffering from non-gonococcal urethritis caused by mixed pathogenic and opportunistic urogenital infection. Clinical characteristics of urethritis in relation to infection pathogen are shown. The results of clinical and laboratory examinations were considered in choice of antibacterial therapy. Safocid, a combined antibacterial medicine, demonstrated its clinical and microbiological efficacy in the treatment of patients with non-gonococcal urethritis of mixed etiology.     

Effect of herpes simplex virus on spermatogenesis

To investigate the effect of Herpes Simplex virus (HSV) on spermatogenesis, HSV in ejaculate was detected by a rapid cultural method in 268 infertile males and 47 healthy ones. The number of mobile spermatozoa in HSV infected samples was less than in non-infected samples (21 mln/mlversus 40 mln/ml, p = 0.0001). The relative number of morphologically normal gametes was 13% versus 19% (p = 0.002), respectively. The quantitative karyological test discovered that males with HSV-infected ejaculate have more degenerating sex cells while in high virus contamination (more than 10 virus particles in 1 ml) the number of spermatides and spermatocytes of the 1 order at diploten stage is low. Organic testicular culture was used for more detailed study of pathogenetic mechanisms of HSV impact on spermatogenesis. Testicular explants infection was associated with reduction in the number of spermatogones, spermatocytes and spermatides on culturing week 2. The above findings reveal some pathogenetic mechanisms underling fertility disorders in males with HSV infection: a gametotoxic effect of the virus reducing populations of spermatogones, spermatocytes and spermatide; affected mobility and morphological characteristics of spermatozoa. Detection of the mechanisms of HSV action on spermatogenesis opens a perspective of antivirus drug administration in combined treatment of male infertility.     

Using zidena in the treatment of erectile dysfunction associated with stress-induced arterial hypertension in workers of locomotive teams

Thirty train drivers with erectile dysfunction (ED) and arterial hypertension were examined : physical examination, blood count, urinalysis, penile laser Doppler flowmetry (LDF). ED severity was assessed by Loran-Segal questionnaire of male copulative function (MCF) and international index of erectile function (IIEF). Zidena was used in a dose 100 mg 30 min before coitus twice a weak. Examinations have detected mild and moderate ED, spastic disorders of penile microcirculation. MCF significant improvement (p < 0.05), rise of IIEF score were seen after 30 days of zidena treatment. A positive trend was observed after 15 days of treatment. LDF registered a significant (p < 0.05) improvement of microcirculation. Tissue hypoxia and ischemia lowered, blood inflow in the system of microcirculation increased. A passive mechanism of blood flow regulation, vasodilation almost corresponded to physiological standards. Administration of zidena in patients with stress-induced hypertension has improved libido, quality and duration of erection, penile microcirculation due to better tissue perfusion with blood, reduction of ischemia and blood congestion in the venules. Duration of coitus increased.     

Experience in vitaprost treatment of patients with chronic abacterial prostatitis and prostatic adenoma after prostatic arteries embolism

Pain and abnormal spermatogenesis are among symptoms deteriorating quality of life in patients with chronic prostatitis. Rectal suppositories vitaprost have no side effects, relieve pain, correct spermatogenesis. The effect of vitaprost treatment persists for 3 months and longer. Prostatic arteries embolization with vitaprost suppositories as preoperative preparation is a good alternative to surgical treatment in patients with prostatic adenoma.     

Echocardiographical evaluation of mean pulmonary artery pressure in patients with chronic obstructive pulmonary disease

We compared Dopplerographic methods and invasive assessment of mean pulmonary artery pressure (MPAP) in 20 men with chronic obstructive pulmonary disease (COPD). We demonstrated possibility of evaluation of mean pulmonary artery pressure by Doppler methods of calculation using diastolic gradient of pressure of pulmonary regurgitation and ratio of flow acceleration time in right ventricular outflow tract and ejection time. In patients with COPD overestimation of MPAP is possible especially in patients with pronounced elevation of MPAP. Methods of evaluation of MPAP based on measurements of intervals of pulmonary blood flow do not allow to adequately evaluate MPAP in patients with COPD.     

Antianginal efficacy and tolerability of ivabradine in the therapy of patients with stable angina: results of the CONTROL study

Control of heart rate (HR) is an important target during treatment of patients with stable angina. In a number of cases it can be achieved by the use of beta-adrenoblockers. But often a necessity arises to enhance pulse slowing therapy with the use of combinations of drugs exerting negative chronotropic effect. We present here results of the CONTROL study (n=1777), conducted with the aim of studying antianginal efficacy and tolerability of the If-channels blocker ivabradine used in combination with beta-adrenoblockers in patients with stable functional class II-III angina and frequency of attacks > or = 3/week and HR>70 bpm. The use of ivabradine for 12 weeks allowed to achieve greater reduction of frequency of anginal attacks (by 4 per week, 95% confidence interval 3-6) compared with the group of usual care (treatment at physicians discretion). At the end of the study in ivabradine group 43% of patients had no angina at all, HR lowering < or =60 bpm was noted in 46% of patients (in the comparison group14 and 6%, respectively, p < 0.001). Reduction of frequency of attacks of angina correlated with HR lowering, more with pulse rate measured by patients themselves (r = 0.411, p < 0.001), than with values measured at visits to physicians (r = 0.266, p < 0.001). Rate of lethal outcomes as well as rate of nonfatal cardiovascular complications (myocardial infarction, stroke, urgent revascularization) were similar in compared groups. In ivabradine group compared with usual care group there were less hospitalizations (5.0 and 8.6%, respectively, p = 0.021), calls for emergency service (13.3 and 25.4%), and sick leaves (6.6 and 13.1%, p = 0.018). Adverse reactions were noted in 130 patients (8.7%) in ivabradine group and in 29 patients (10.0%) in usual care group p = 0.580).
