Analysis of Long Non-Coding RNA (lncRNA) UCA1, MALAT1, TC0101441, and H19 Expression in Endometriosis.

Endometriosis is a disease of complex etiology. Hormonal, immunological, and environmental factors are involved in its formation. In recent years, special attention has been paid to genetic mechanisms that can have a significant impact on the increased incidence of endometriosis. The study aimed to analyze the expression of four long non-coding RNA (lncRNA) genes, UCA1, MALAT1, TC0101441, and H19, in the context of the risk of developing endometriosis. The material for genetic testing for the expression of lncRNA genes were tissue slices embedded in paraffin blocks from patients with endometriosis (n = 100) and the control group (n = 100). Gene expression was determined by the RT-PCR technique. The expression of the H19 gene in endometriosis patients was statistically significantly lower than in the control group. A statistically significant association was found between H19 gene expression in relation to The Revised American Society for Reproductive Medicine classification of endometriosis (rASRM) in the group of patients with endometriosis. Research suggests that H19 expression plays an important role in the pathogenesis of endometriosis.

Postnatal inversion of the uterus - management in specific cases.

Inversion of the uterus is defined as the turning inside out of the fundus into the uterine cavity. According to the literature, uterine inversion occurs in 1/20,000 or even 1/1,584 deliveries. Mortality rates following acute uterine inversion were reported by some authors to have been as high as 80%. Therefore, it is very important to make an early diagnosis. The shorter the time between the moment of uterine inversion and its repositioning, the better the results of conservative treatment, and bigger chance of avoiding surgical management. The article presents two cases of patients hospitalised in 2010 - 2011 in the Gynaecologic and Obstetrics Department of the Regional Polyclinic Hospital in Kalisz, Central Poland, diagnosed with acute uterine inversion in accordance with the applicable classification. Surgical management was applied in one of the patients. The other patient was managed in a conservative manner. Both women were discharged from the hospital in a good general condition.
