Cardiac metastasis from endometrial cancer is a very rare finding. The article presents a case of death, demonstrating the aggressive clinical course of endometrial serous carcinoma. In this clinical example the disease was accompanied by generalized metastasizing through a lymphogenous route to unexpected distant organs (peribronchial lymph nodes, pleura, pericardium).

n the case of a space-occupying lesion (SOL) of the ovary, it is up to the gynecologist to diagnose a possible malignancy and then decide upon further treatment strategy. The aim of the study was to perform a comparative analysis of the existing methods for detecting the tumor markers: CA-125 – cancer antigen 125 and HE4 – human epididymis protein 4. We also compared the prognostic indices (Risk Malignancy Index – RMI and Risk of Ovarian Malignancy Algorithm – ROMA) currently used to make differential diagnoses of benign and malignant ovarian neoplasms at the preoperative stage. Materials and methods. We conducted a prospective study in 100 patients from 18 to 79 years old scheduled for surgery for an ovarian SOL. The serum levels of the CA-125 and HE4 tumor markers, pelvic sonography, the RMI and ROMA scores, as well as post-surgery histopathology results were evaluated. Results. The sensitivities of the CA-125, HE4, RMI and ROMA indices were 85.7%, 42.9%, 85.7% and 71.4%, respectively; the values of specificity were 83.6%, 97.8%, 96.7%, 97.8%, respectively. Conclusion. The most informative parameter for the differential diagnosis of benign and malignant ovarian neoplasms at the preoperative stage was the RMI, and the least informative – the HE4 tumor marker. The HE4 determination was highly informative, however, in the differential diagnosis of ovarian malignant neoplasms with endometrioid cysts in patients with elevated CA-125 levels. Notably, patients with widespread external genital endometriosis showed false-positive results of the CA-125, HE4, RMI and ROMA tests. In a patient with clear-cell ovarian carcinoma, the sensitivity and specificity of the CA-125, HE4, RMI, and ROMA tests were confirmed to be low.

The test groups of animals showed different reaction on the presence of electric power line (EPL) glades, which cross light and dark conifer formations. The microarthropods react on the changes of hydrotermic soil conditions in a higher degree. The direct influence of electromagnetic field on the population density of soil invertebrates has place in both forest formations, but with opposite consequences. The same is demonstrated by herpetobium elements: the clear dominance of «meadow» species in fir formations and the absence of this in pine parts. Small mammals on the LEP glades increase their abundance and species diversity. They also demonstrate that their distribution is dominated by food and protection conditions. But at the same time, the distribution of constant rodent winter refuges demonstrate the negative effects of EPL existence. The analysis of bird populations on the basis of optimal life conditions demonstrated a highest negative effect of electromagnetic field of EPL. Independently of the creation of good protection, food and nesting conditions for birds, which usually occupy open biotopes and bush with herb thickets, they avoid the EPL glades. The first results showed the dual effect of EPL glades on animal populations. It is necessary to take into account the forming of intrazonal locations and real electromagnetic effects. The significant conclusions are found for birds, because they receive more irradiation. Also some biological peculiarities are important: the migratory species have a possibility to react immediately, according to the season, on the changing of biotopes. As for other animal groups, it is necessary to prolong the study of seasonal changes. For the invertebrates it must be performed the instrumental analysis of the differences of hydrotermic conditions of EPL glades and native biotopes.
