Past obstetric history and risk of ovarian cancer

81%
Introduction: Early age at menarche and late age at last menstrual period, as well as other reproductive factors, may be the cause of development of some types of cancer concerning the female reproductive organs. It has been estimated that late menopause may be responsible for the occurrence of even 16% of cases of ovarian cancer in the population. The incidence of ovarian cancer is also higher among nulliparous women, and among those who rarely become pregnant. Objective: The objective of the study was analysis of the effect of reproductive factors on the risk of ovarian cancer. Methodology: The study covered healthy women, without the diagnosis of focal lesions in the ovaries, and women with the diagnosis of ovarian cancer. The study was conducted during the period from September 2007 – November 2011, and covered a total number of 1,346 women. Odds ratio was calculated for individual risk factors. Statistical analysis was performed by means of the statistical packages STATISTICA v8, GrafPad Instat v 3.00, Analyse-it v. 2.2, and Cytel Studio StatXact-8. Statistical hypothesis were verified on the level of significance p ≤ 0.05. Results: Among females who began menstruating by the age of 11, the risk of ovarian cancer was 1.6 higher than among those in whom the first period occurred at the age of over 13. Similarly, among women who menstruated at the age of over 55 the risk of development of ovarian cancer was 1.4 times higher. The age at which a woman delivered her first live baby is also of importance. In the group of women who gave birth at the age of over 35, the risk was elevated and remained on the level of OR=1.7; 95%CI 0.66-4.5, compared to those who bore the first baby under the age of 25. If the pregnancy was terminated with miscarriage, the risk of contracting ovarian cancer decreases, and was on the level of OR=0.8; 95%CI 0.53-1.28, compared to the women who have never been pregnant. Among patients who did not breastfeed their babies, ovarian cancer risk was 1.7 times higher, compared to those breastfeeding. Conclusion: Reproductive factors exert a significant effect of the risk of development of ovarian cancer.
Introduction. Pregnancy, parturition and childcare, which are important moments in a woman’s life, are connected with many emotional states of a future mother, a pregnant woman and a lying-in woman. The perinatal period is the time when the risk of psychological disorders in a pregnant woman may increase by even several times. Objective. The objective of the study was recognition of the main emotional and psychological changes in pregnant women, those in labour and lying-in, according to the factors occurring during the peripartum period. Material and method. The study was conducted in the form of a survey and covered a group of 108 mothers who were hospitalized in gynaecological-obstetric and obstetric wards in the Karol Marcinkowski Gynaecological-Obstetric University Hospital in Poznań. Results. There are a number of factors which may exert a negative effect on the emotions of women in pregnancy, parturition, and during lying-in. The study showed that there is a close relationship between the occurrence of these factors and emotional states of the mothers after giving birth. Conclusion. Special attention should be given to women in whom already during pregnancy factors arise which may have a negative impact on their mental state. Emotions during pregnancy, parturition and lying-in are often quite extreme, and achieve a high intensity, as well being very variable within a short period of time.
Introduction: Many risk factors may be monitored, and individual decisions concerning life style exert an effect on most factors associated with the development of cancer. It is estimated that the majority of malignant cancers, as much as 70%, are the result of the harmful effect of factors related with diet, life style, or those present in the surrounding environment. Objective: The objective of the study was analysis of selected factors related with life style and their effect on the risk of development of breast and ovarian cancer. Methodology: The study covered healthy women, without the diagnosis of focal lesions in the breast and ovaries, and women with the diagnosis of breast or ovarian cancer. The study was conducted during the period September 2007 – November 2011, and covered a total of 1,484 women aged 18-80. Odds ratio was calculated for individual risk factors. Statistical analysis was performed by means of the statistical packages STATISTICA v8, GrafPad Instat v 3.00, Analyse-it v. 2.2, and Cytel Studio StatXact-8. Statistical hypothesis were verified on the level of significance p ≤ 0.05. Results: Health-promoting life style related with physical activity and other health promoting behaviours, such as mode of nutrition, reduction or elimination of alcohol consumption and discontinuation of smoking considerably decrease the risk of development of malignant breast and ovarian cancer. The number and variety of factors which affect the risk of occurrence of cancerous diseases indicate that there is a need for monitoring of the hazard. Conclusion: It is necessary to carry out preventive actions which would cover the health education of women, concerning life style-related risk factors and methods of their modification.
Objectives: Premature rupture of the membranes (PROM) in pregnancy refers to rupture of membranes of the amniotic sac and chorion. The aim of the study was to review the literature and analyze the course of pregnancy (primipara) complicated by the premature rupture of the membranes, and consequent loss of amniotic fluid after 19 weeks of gestation. Study design: A 27-year old primiparous patient was admitted to the Gynaecology and Obstetrics University Hospital in Poznań on 9 December 2010, due to suspected premature rupture of the membranes. On presentation, foetal development was at 19 weeks gestation. Standard clinical investigations included ultrasonography, amniotic fluid index measurements and laboratory blood tests. Results: Ultrasonography confirmed the size of the foetus to be normal for the gestational age. However, no amniotic fluid pockets were visible and the amniotic fluid index was 0 cm. The patient was hospitalized on multiple occasions and as a result a decision was made to end the pregnancy prematurely by means of a caesarean section at 32 weeks of gestation. Longer-term observation of the newborn indicated that one year following delivery, the development of the baby was normal, and thus far no neurological injuries or complications have been observed. Conclusion: The pregnancy was ultimately successfully completed with the delivery of a healthy newborn at 32 weeks of gestation. A regime involving rigorous bed rest and antibiotic administration can positively extend the duration of pregnancies complicated by premature rupture of the membranes.
