    Background. The prevalence of premature ovarian failure (POF) of 1 % has important psychosocial consequences and impact on general health. Besides known etiology (genetic, chromosomal, infections, iatrogenic) autoimmunity can be the pathologic mechanism for POF. Material and methods. Eleven women with POF, with excluded other reasons for the disease except autoimmunity were included in this study. The control group consisted of 13 healthy normo-ovulatory women. In both groups targeted family and personal history was taken and determinations of: FSH, LH, TSH, prolactin, antimüllerian hormone (AMH), inhibin B, thyroid antibodies TG and TPO. At the cellular level periferal blood T-lymphocytes were analyzed by flow cytometry, on humoral level ovarian antibodies were detected with indirect immunofluorescence on human ovary sections. Quick ACTH test was performed in study group only. Results. In 9 patients POF was associated with another autoimmune disease. Six patients of the study group (55 %) presented very elevated thyroid autoantibodies TG and TPO, in the control group the levels of both autoantibodies were within normal range. Hormonal analyses in the study group exhibited the values of hypergonadotropic hypogonadism and consequently low levels of inhibin B and AMH. Lymphocyte subset in study group namely CD4+, CD19+ and CD8+ was significantly higher, while natural killer cells and regulatory T cells were significantly lower then in the control. group. In 4 patients (36 %) antiovarian autoantibodies were detected. Results of the quick ACTH test in the study group were normal. Conslusions. POF is frequently associated with autoimmune disorders. The presence of antithyroid and antiovarian antibodies together with abnormalities of the cellular immunity can potentionally represent an autoimmune mechanism of POF. The question of immunomodulatory therapy in selected patients with POF is open

    Background. Radical hysterectomy is performed on woman with cervical cancer or endometrial cancer that has spread to the cervix. Aims. To find whether our modified radical hysterectomy represents nerve sparing. Methods. In 28 patients, modified radical hysterectomy was applied (study group) and the width of the parametria and vaginal cuff were measured. Using a point-counting technique, nerve areal density was determined in cross sections of resected parametria at 0.5 cm (A), 1 cm (B), and 1.5 cm (C) from the cervix. The results were compared with 26 control patients who underwent classic radical hysterectomy. In the study group urodynamic measurements were performed after operation, and correlations with histologic data were calculated. The survival rates and adjuvant treatment were compared between the groups. Results. Adjuvant treatment was given to 53.57 % in the study and 65.38 % of patients in the control group (P > 0.3). The survival rate after 3 years was 92.85 % in the study and 84.61 % in the control group after more than 5 years. The width of the resected parametria was smaller in the study (mean: right 15.50 mm, left 15.71 mm) compared with the control group (mean: right 22.69 mm; P < 0.013; left 22.96 mm; P < 0.011). The nerve areal density in the lateral part of the right parametrium (C right 6.2 %) was lower in the study than in the control group (C right 9.7 %; P < 0.01). There were several correlations between parametrial width, nerve areal density and urodynamic parameters. Conclusions. Modified radical hysterectomy is less radical, and apparently also nerve sparing. It does not influence survival rates and does not impair the urinary tract function
