Disparities and relative risk ratio of preterm birth in six Central and Eastern European centers.

AIM: To identify characteristic risk factors of preterm birth in Central and Eastern Europe and explore the differences from other developed countries. METHOD: Data on 33,794 term and 3867 preterm births (<37 wks.) were extracted in a retrospective study between January 1, 2007 and December 31, 2009. The study took place in 6 centers in 5 countries: Czech Republic, Hungary (two centers), Romania, Slovakia, and Ukraine. Data on historical risk factors, pregnancy complications, and special testing were gathered. Preterm birth frequencies and relevant risk factors were analyzed using Statistical Analysis System (SAS) software. RESULTS: All the factors selected for study (history of smoking, diabetes, chronic hypertension, current diabetes, preeclampsia, progesterone use, current smoking, body mass index, iron use and anemia during pregnancy), except the history of diabetes were predictive of preterm birth across all participating European centers. Preterm birth was at least 2.4 times more likely with smoking (history or current), three times more likely with preeclampsia, 2.9 times more likely with hypertension after adjusting for other covariates. It had inverse relationship with the significant predictor body mass index, with adjusted risk ratio of 0.8 to 1.0 in three sites. Iron use and anemia, though significant predictors of preterm birth, indicated mixed patterns for relative risk ratio. CONCLUSION: Smoking, preeclampsia, hypertension and body mass index seem to be the foremost risk factors of preterm birth. Implications of these factors could be beneficial for design and implementation of interventions and improve the birth outcome.

Prevalence and impact of restless legs syndrome in pregnancy.

BACKGROUND: Restless legs syndrome (RLS) is a frequent neurological disorder which predominantly affects women. Pregnancy is one of the most common conditions leading to secondary RLS. Severe symptoms of RLS may lead to complications of pregnancy and/or labor. The aim of this study was to determine the prevalence and characteristics of RLS in pregnant women. METHODS: Women in the third trimester of gravidity filled out a simple questionnaire based on the official diagnostic criteria for RLS. Positive responders were interviewed in order to further characterize their symptoms. Afterwards information on changes in frequency and/or intensity of the symptoms after delivery was obtained by a telephone follow-up. All data were statistically analysed. RESULTS: A total of 300 questionnaires were completed. All 94 RLS-positives met the four diagnostic criteria (31.33%). There was no difference in age, body mass index, or the number of previous pregnancies between RLS-positives and RLS-negatives, but weight gain during pregnancy was significantly higher in RLS-positives. More than 30% of positives had clinically significant symptoms, and 50% reported sleep disturbances. Almost 75% of the cases of RLS were secondary, i.e., symptoms occurred only during pregnancy (with a peak in the third trimester). More complications of pregnancy or labor occurred in women with RLS, but this was only marginally significant. CONCLUSIONS: Our study confirmed the relatively high prevalence of RLS in pregnant women compared with the general population. Although almost three-fourths of the symptoms were only transient throughout pregnancy, the impact of the severe symptoms and sleep deprivation on the course of pregnancy and delivery was not negligible. Early detection and adequate treatment of severe RLS are necessary to prevent maternal discomfort and possible health risks. The questionnaire method is a simple, reliable diagnostic tool.

Emergency Uterine Artery Embolization Used for Managing Profuse Intra-Abdominal Bleeding and Uterine Rupture in a Patient with Advanced Cervical Cancer.

Advanced cervical cancer can lead to life-threatening vaginal bleeding. Emergency uterine artery embolization (UAE) has been successfully used in such cases to achieve hemostasis. Our case demonstrates the unusual emergency use of this procedure to cease heavy hemorrhage, which led to hematometra, uterine rupture and hemoperitoneum in a patient with a large tumor in the cervical region. Vaginal bleeding was minimal in this case. The emergency UAE controlled the bleeding, and the patient was scheduled for laparotomy soon after the procedure, where a supracervical hysterectomy with bilateral salpingo-oophorectomy and the removal of blood and blood clots was performed. Since the tumor primarily involved the parametria, a sample was taken for histopathology examination with the following result: squamocellular HPV-associated cervical carcinoma. The postoperative management of the patient consisted of combined chemotherapy and radiotherapy, with no complications related to the UAE. Four months after the procedure the patient is reasonably well. Urgent surgery was not the optimal decision because of the alteration of the pelvic anatomy by the tumor, and thus the UAE enabled us to manage this life-threatening condition quickly, allowing us to best prepare the patient for further therapeutic modalities.

Effect of Ornithine Transcarbamylase (OTC) Deficiency on Pregnancy and Puerperium.

Ornithine transcarbamylase (OTC) deficiency is the most common inherited metabolic disorder in urea cycles with an incidence of 1:14,000 live births. Pregnancy, childbirth and the postpartum period are considered challenging for women with this hereditary metabolic disorder, with a risk of hyperammonemia, especially in the first week after delivery. In our article, we discuss severe hepatic failure, a pregnancy complication in an OTC deficient patient that has not previously been published. Firstly, our aim is to highlight the need for a strict adherence to the recommendation of the gradual increase of protein intake during pregnancy and the importance of multidisciplinary monitoring of pregnant patients with OTC deficiency. Secondly, we refer to critical postpartum hyperammonemia in patients with this hereditary metabolic disorder.

Prenatal Diagnosis of Torcular Dural Sinus Malformation: A Case Study.

Torcular dural sinus malformations (tDSMs) are rare congenital defects representing a complex of vascular anomalies that have been grouped in one single unit. Although the current literature suggests a generally favourable prognosis for prenatally diagnosed tDSMs, there are still only limited data and published papers on the subject. Factors resulting in an adverse outcome of the fetuses and children have to be taken into consideration to determine precisely the nature of the consultation and management. A 33-year-old primipara at 21 weeks, 5 days of gestation was referred to our clinic with the suspicion of a central nervous system (CNS) malformation of the fetus, and the diagnosis of tDSM with thrombus was made. No factors contributing to an adverse outcome such as arterialization of the lesion, ventriculomegaly or neuroparenchymal damage were present. The pregnant woman was scheduled for regular sonographic and magnetic resonance imaging (MRI) controls. In the third trimester the lesion decreased in size, which is a key imaging marker for a favourable prognosis. The child was born in term, and the latest neurological examination at the age of six weeks is without pathological findings. This case study demonstrates a prenatally diagnosed tDSM with a favourable outcome with a regression in the size of the lesion during the prenatal period.

Restless legs syndrome in pregnancy is connected with iron deficiency.

OBJECTIVE: Almost one-third of pregnant women develop symptoms of restless legs syndrome (RLS), which could have a negative impact on quality of life and the course of pregnancy and/or labor. The aim of our study was to determine possible risk factors for developing RLS in pregnant women. METHODS: A total of 300 random women in the third trimester of gravidity filled out a simple questionnaire based on the official diagnostic criteria for RLS. Respondents positive for RLS were interviewed to further characterize their symptoms. The parameters of iron metabolism were examined based on blood samples. All data were statistically analyzed. RESULTS: We detected significantly lower hemoglobin levels with signs of hypochromic anemia typical of iron deficiency in RLS-positive respondents, although oral iron supplementation was significantly higher in this group. The overall severity of symptoms correlated inversely with hemoglobin level. CONCLUSION: According to our results, it appears that serum iron level disturbances play a crucial role in the pathophysiology of secondary RLS in pregnant women.
