Summary Objective: The aim of this study was to observe the variability of the level of copper, zinc and manganese in saliva amongst women with hypoestrogenia, treated and untreated with hormone replacement therapy (HRT). Methods: The study was conducted on a group of 60 women treated and untreated with HRT. Half of the patients were after natural menopause and other half was after surgical removal of ovaries. Research on micronutrients in non-stimulated saliva and blood serum was carried out in 2005. Tests on saliva were repeated in 2010. Investigation of bone mineral density (BMD) of femoral bone was performed in year 2010. Results: Statistical analysis of concentration of copper and zinc revealed a linear correlation between the levels of these microelements in blood serum and saliva. The study revealed that HRT has a beneficial effect on BMD and the concentration of copper and manganese in saliva and blood serum of patients after the menopause. Patients treated with HRT showed higher BMD values than groups not treated with hormones. Conclusions: Saliva appears to be a promising diagnostic material which can be used to analyze the content of trace elements, but further research should be carried out on a broader research group.

Summary Aim: One therapeutic approach to rheumatoid arthritis and other inflammatory arthropathies besides surgical removal of inflamed synovium is radiation synovectomy using beta-emitting radionuclides to destroy the affected synovial tissue. Up to now the major problem associated with the use of labeled particles or colloids has been considerable leakage of radionuclides from the injected joint coupled with high radiation doses to liver and other non target organs. In this study we compared 188Re labeled hydroxyapatite particles and 188Re rhenium sulfur colloid for their potential use in radiation synovectomy. Methods: To this end we varied the labeling conditions (concentrations, pH-value, heating procedure) and analyzed the labeling yield, radiochemical purity, and in vitro stability of the resulting radiopharmaceutical. Results: After optimizing labeling conditions we achieved a labeling yield of more than 80% for 188Re hydroxyapatite and more than 90% for the rhenium sulfur colloid. Both of the radiopharmaceuticals can be prepared under aseptic conditions using an autoclav for heating without loss of activity. In vitro stability studies using various challenge solutions (water, normal saline, diluted synovial fluid) showed that 188Re labeled hydroxyapatite particles lost about 80% of their activity within 5 d in synovial fluid. Rhenium sulfur colloid on the other hand proved to be very stable with a remaining activity of more than 93% after 5 d in diluted synovial fluid. Conclusion: These in vitro results suggest that 188Re labeled rhenium sulfur colloid expects to be more suitable for therapeutic use in radiation synovectomy than the labeled hydroxyapatite particles.

Background: Sticker sarcoma, also called venereal sarcoma or venereal lymphosarcomatosis, is a tumor of the external genital organs in females and males. In male animals the penis and foreskin (prepuce) are affected, in the female, it happens in vagina (vagina) and labia (vulva). The diagnosis of sticker sarcoma is based on the chronic discharge, the typical locations and the characteristic appearance of the tumor. Methods: We have relied on the treatment method on the complete surgical removal of all cancer cells that we can access. Results: After surgery, we notice recurrent tumors about six months after surgical treatment, indicating the need for other treatments in addition to surgery. Conclusion: Although spontaneous regressions of sticker sarcoma are documented (with permanent immunity), chemotherapy is the treatment of choice today. Irradiation should also be effective. If the tumor is only removed surgically, there is a high rate of recurrence, and this is what happened with the case that we treated, as the tumor reappeared after less than six months.

Liver metastases of gastric cancer determine the poor prognosis. Until now The expediency of their surgical removal has been controversial. However, according to a number of studies, the removal of potentially operable isolated liver metastases allows a significant increase of overall and relapse-free survival in some cases. The review is dedicated to the analysis of prognostic factors that allow selecting patients for surgical removal of liver metastases of gastric cancer. The main criteria are: effective perioperative chemotherapy; stage under T4, N0, absence of lymphovascular invasion, absence of peritoneal dissemination, number less than 3, size up to 4 cm, localization of metastases in one lobe, low level of cancer markers CA 19-9 and CEA.

Cavernous hemangiomas are benign tumours of mesodermal origin. Even though various localizations of hemangioma have been described in the literature, its occurrence in the greater omentum is very rare. Only symptomatic hemangiomas are indicated for surgical treatment. There are case reports presenting resection or surgical removal of the greater omentum with hemangioma because of mechanical syndrome, consumption coagulopathy, bleeding, infection or suspicion of a malignancy. This article presents a case report of a patient operated on for a suspicion of carcinomatosis of the greater omentum. Histological examination found hemangiomatosis in the resected greater omentum.
