Obstetric gel shortens second stage of labor and prevents perineal trauma in nulliparous women: a randomized controlled trial on labor facilitation

OBJECTIVE: To determine whether the obstetric gel shortens the second stage of labor and exerts a protective effect on the perineum. METHOD: A total of 251 nulliparous women with singleton low-risk pregnancies in vertex position at term were recruited. A total of 228 eligible women were randomly assigned to Group A, without obstetric gel use, or to Group B, obstetric gel use, i.e., intermittent application into the birth canal during vaginal examinations, starting at the early first stage of labor (prior to 4 cm dilation) and ending with delivery. RESULTS: A total of 183 cases were analyzed. For vaginal deliveries without interventions, such as C-section, vaginal operative procedure or Kristeller maneuver, obstetric gel use significantly shortened the second stage of labor by 26 min (30%) (P=0.026), and significantly reduced perineal tears (P=0.024). First stage of labor and total labor duration were also shortened, but not significantly. Results did not show a significant change in secondary outcome parameters, such as intervention rates or maternal and newborn outcomes. No side effects were observed with obstetric gel use. CONCLUSION: Systematic vaginal application of obstetric gel showed a significant reduction in the second stage of labor and a significant increase in perineal integrity. Future studies should further investigate the effect on intervention rates and maternal and neonatal outcome parameters.     

Hypercalcemia in Pregnancy Due to CYP24A1 Mutations: Case Report and Review of the Literature

Pathogenic mutations of CYP24A1 lead to an impaired catabolism of vitamin D metabolites and should be considered in the differential diagnosis of hypercalcemia with low parathyroid hormone concentrations. Diagnosis is based on a reduced 24,25-dihydroxyvitamin D to 25-hydroxyvitamin D ratio and confirmed by genetic analyses. Pregnancy is associated with an upregulation of the active vitamin D hormone calcitriol and may thus particularly trigger hypercalcemia in affected patients. We present a case report and a narrative review of pregnant women with CYP24A1 mutations (13 women with 29 pregnancies) outlining the laboratory and clinical characteristics during pregnancy and postpartum and the applied treatment approaches. In general, pregnancy triggered hypercalcemia in the affected women and obstetric complications were frequently reported. Conclusions on drugs to treat hypercalcemia during pregnancy are extremely limited and do not show clear evidence of efficacy. Strictly avoiding vitamin D supplementation seems to be effective in preventing or reducing the degree of hypercalcemia. Our case of a 24-year-old woman who presented with hypercalcemia in the 24th gestational week delivered a healthy baby and hypercalcemia resolved while breastfeeding. Pathogenic mutations of CYP24A1 mutations are rare but should be considered in the context of vitamin D supplementation during pregnancy.     

A Complex Negotiation: Women's Experiences of Naming and Not Naming Premenstrual Distress in Couple Relationships

ABSTRACT

Recent research has demonstrated the importance of family relationships in women's experience of premenstrual changes, their construction of these changes as “PMS.” However, the discursive process by which women take up the subject position of “PMS” sufferer through the explicit naming of “PMS” to an intimate partner has received little research attention. Drawing on 60 individual interviews with Australian women, conducted between 2004 and 2006, we examined accounts of naming “PMS” in intimate relationships, women's explanations for naming or not naming, their experiences of their partner naming them as premenstrual. The analysis process identified an overarching theme of naming “PMS,” which was made up of three themes: naming to explain; “PMS” becoming the only explanation for distress; “PMS” as not a legitimate explanation for distress. The findings suggest that clinicians need to be aware of women's complex, often ambivalent, experiences of naming “PMS” within their relationships, when working with women, couples, seeking treatment or support for premenstrual distress.     

Psychological defence and nuclear war

Society is influenced by the unconcious aspects of the minds of the member individuals. This paper describes a psychoanalytic approach to some aspects of the social processes that give rise to the attitudes in Western society towards nuclear war and the nuclear threat. It is concluded that there are profound hidden factors that work against changing the current views on war and nuclear war, and that some peace groups are inadvertently recruited into maintaining the status quo.     

Ideological commitment,experience of conflict and adjustment in Northern Irish adolescents

The main delayed effect of ionizing radiation in the individual is the induction of cancer. However, for low doses (less than 100 mSv effective dose equivalent), there is no direct evidence of radiation‐induced cancer, with the possible exception of childhood cancer following prenatal exposure to X‐rays. The risk at low doses has to be estimated from the observed risk at high doses; there are considerable uncertainties in this extrapolation. Direct study of those exposed to low doses does not produce any more precise information, although it does impose boundary conditions on the risk. Currently the most important problem in environmental radiation exposure is the increased incidence of childhood leukaemia observed around some nuclear installations; the explanation for this remains unclear.
